[0024] The working principle is: first, manually stack batches of copper foil substrates vertically on the placement platform, and send the cart into the chamber. At this time, the sensor component installed inside the frame is located above the placement platform. As the internal material is transferred, the height of the material placed on the placement platform changes. The sensor component senses the change in material height and synchronously drives the lifting part. The lifting part drives the placement platform to rise according to the change in material height, thereby reducing the descending stroke of the subsequent material transfer component when grabbing the material. At the same time, when adding materials, you only need to pull out the cart assembly, and the cart assembly can drive the placement platform to be pulled out together, which improves the convenience of adding materials, avoids the trouble of manually placing copper foil substrates one by one, improves loading efficiency, and thus increases production capacity.

[0025] The utility model can stack materials in batches and place them on a placement platform, and set the placement platform on a trolley assembly that can be easily pushed and pulled, thereby improving the convenience of taking and placing materials. In conjunction with the sensor assembly and the jacking assembly inside the frame, the device can quickly and conveniently lift materials to meet the grasping requirements of the subsequent grasping mechanism, making it convenient for the device to quickly load materials.

[0027] The working principle is: when it is necessary to add materials into the device, first pull the cart assembly 2 out from the inside of the chamber. At this time, the cart assembly 2 is pulled out along the opening direction of the chamber under the drive of the self-locking universal wheel 204. At this time, the cart assembly 2 drives the placement platform to be pulled out, so that the materials can be conveniently placed on the placement platform.

[0028] The utility model can arrange a trolley assembly 2 that can be pushed and moved on the ground by an external force, and place materials on a placement platform, thereby realizing convenient material loading through the push-pull trolley assembly 2.

At this time, the driving rod of the lifting cylinder rises and lifts up the placement platform, so that the subsequent grasping mechanism can grasp the material stably, avoiding manual loading and using the automated lifting component 101 to lift the material, thereby improving the loading efficiency.

[0034] The utility model can reduce the weight of the cart assembly 2 and simplify the structure of the cart assembly 2 by setting a lifting member that is placed separately from the cart assembly 2, without affecting the lifting of materials by the device, so as to facilitate subsequent loading of materials in the cart assembly 2.
