A thickness meter detects a thickness of an electrode plate of a secondary battery at three or more points in a width direction of the electrode plate. A calculator calculates three feature amounts of a first deviation between the thickness target value and a thickness measurement value of a point closest to a first compression mechanism among the three or more points, a second deviation between the thickness target value and a thickness measurement value of a point closest to a second compression mechanism among the three or more points, and a secondary component of a thickness profile of the electrode plate from thickness measurement values at the three or more points and the thickness target value, and adaptively changes the setting values of the first compression mechanism, the second compression mechanism, a first bend mechanism, and a second bend mechanism on the basis of the three feature amounts.

A stamp tool assembly is provided that includes a forming cavity for shaping a blank into a formed part. The stamp tool assembly includes adjustable block assembly for modifying the amount of material draw-in from subsequently stamped blanks. A draw-in sensor measures the amount of material from the blanks that is not drawn-into the forming cavity during each stroke. Based on the readings from the draw-in sensor, the adjustable block assembly is expanded or reduced. The adjustable block assembly includes a pair of opposing inclined plates having interlocking teeth such that movement of one plate with respect to the other plate changes a vertical extension of the adjustable block assembly. The adjustable block assembly sets the spacing between two opposing draw-in surfaces, which, in turn, changes the amount of draw-in. Multiple adjustable block assemblies and draw-in sensors may be used in conjunction and controlled via a controlling system.

A heat press includes a base, a handle, a controller, a heater arm, a pressure link, a lower platen, and an upper platen. The handle is pivotally coupled to the base. The controller is integrally formed with the handle. The heater arm is pivotally coupled to the base. The pressure link is pivotally coupled to the handle and the heater arm. The lower platen is connected to base. The upper platen is connected to the heater arm. A surface of the upper platen is separated from a surface of the lower platen in a first position, and the surface of the upper platen is in contact with the surface of the lower platen in a second position.

Systems, devices, and methods are disclosed for a rosin press that allows improved extraction over existing presses. The press includes improved platens for rosin collection with built-in gutter rail collection systems and well-distributed force on the pressed product and multiple hydraulic rams. In addition, computerized systems are provided for controlling and monitoring the system in an automated fashion, as well as safety features to prevent injury and damage to the product, especially during automated pressing.
