[0002] As we all know, in order to ensure the quality and reliability of chip capacitor products, they need to be performance tested during the production process. Currently, there are automatic testing equipment for chip capacitors. During the operation of the testing equipment, manual labor is required to frequently add materials to the material tray, which takes up human resources and increases workload. Secondly, the hatch needs to be opened during the adding process, and the robot is in a servo state, which will bring safety hazards to the staff. In addition, the automatic testing equipment needs to be interrupted during the adding process, thereby reducing the working efficiency of the automatic testing equipment. Utility Model Content

[0003] The problem to be solved by the utility model is to provide a graded feeding device, which utilizes an internal and external two-stage feeding mechanism. Manual operation only needs to add materials to the hopper outside the equipment door, without frequently opening the equipment door, thereby solving the current problems of large manual operation workload, low equipment operation efficiency, and safety hazards of manually opening the door to add materials.

[0004] The technical solution adopted in this utility model is:

[0005] A graded feeding device, which includes an outer silo and an inner silo, the outer silo including an outer silo reinforcement plate, an outer silo mounting plate fixed above the outer silo reinforcement plate, the outer silo mounting plate connected to the outer silo hopper through four lifting screws, the outer direct vibration silo connected to the direct vibration module, the direct vibration counterweight and the direct vibration module fixed above the direct vibration connecting block, the direct vibration connecting block connected to the outer silo mounting plate through a rubber sleeve; the inner silo including an inner silo mounting plate, a flexible vibration disk main module fixed above the inner silo mounting plate, the inner direct vibration silo connected to the flexible vibration disk main module through the inner silo fixing seat, and the flexible vibration disk connected to the flexible vibration main module.

[0006] The outer silo reinforcement plate and the outer silo mounting plate fix the outer silo outside the automatic testing equipment, and the inner silo mounting plate fixes the inner silo inside the automatic testing equipment. The interior and exterior of the automatic testing equipment are separated by a hatch.

[0007] The height of the external hopper is adjusted by a lifting screw, and the hopper has no contact with the external direct vibration hopper. The discharge speed can be controlled by adjusting the distance between the hopper and the external hopper to adapt to logistics of different sizes.

[0008] The outer direct vibration silo is connected to the direct vibration module, and the material is transported to the inner direct vibration silo in the inner silo under the vibration of the direct vibration module.

[0009] The vibration frequency and amplitude of the direct vibration module are adjustable and can be triggered by an external signal source.

[0010] The flexible vibration main module has an RS232 control interface and an external trigger signal interface. The flexible vibration main module is connected to the computer through the RS232 control interface. The vibration frequency, amplitude and vibration direction parameters are set through the flexible vibration module control software, and the external signal triggers the flexible vibration main module to work.

[0011] The inner straight vibration silo can transport materials to the flexible vibration plate in the flexible vibration plate main module, and the flexible vibration plate can vibrate in any direction under the action of the flexible vibration plate main module.

[0012] The flexible vibration plate is a material visual recognition grabbing area, and the robotic arm grabs the material in the flexible vibration plate.

[0013] The beneficial effects of the utility model are:

[0014] 1) The feeding device provided by the utility model realizes automatic feeding of materials not limited to chip components, solving the problem of increased workload of current manual operation. Manual materials can be added externally at one time without opening the hatch. Automatic feeding is achieved through the cooperation between the inner and outer silos, thereby improving the working efficiency of the test equipment, reducing the workload of the staff, and reducing safety hazards.

[0015] 2) The height between the hopper and the external vibration bin can be adjusted by the lifting screw, which can control the feed amount to a certain extent and can adapt to materials of different sizes.

[0016] 3) The direct vibration connection block is connected to the external silo mounting plate through a shock-absorbing rubber sleeve, which can effectively reduce the impact of the direct vibration module on the equipment during operation.

[0017] 4) The flexible vibration main module can independently control the internal straight vibration silo and the flexible vibration plate. The flexible vibration main module can control the feeding speed of the internal straight vibration silo. The flexible vibration main module can also adjust the vibration frequency, amplitude and vibration direction of the flexible vibration main module to achieve the distribution of materials in any direction on the flexible vibration plate and realize automatic turning of materials.

[0018] 5) The staff fills the hopper with materials at one time, and the materials fall into the external direct vibration silo. The external direct vibration silo can be triggered by an external signal, and the external direct vibration silo transports the materials to the internal direct vibration silo. The internal direct vibration silo vibrates the materials into the flexible vibration plate. The flexible vibration plate can automatically turn the materials over and vibrate in any direction, which is convenient for visual recognition and grasping of materials. The various components cooperate with each other to achieve efficient feeding. BRIEF DESCRIPTION OF THE DRAWINGS
