Description

Technical Field

[0001] This application relates to the technical field of solar cell sorting, and more specifically, to a solar cell unloading device. Background Technology

[0002] When sorting solar cells, a sorting machine is used to determine whether the cells are qualified. The sorting process is divided into a loading and unloading buffer area. For unloading the solar cells, a specialized solar cell unloading device is used. This device includes a conveying section, an unloading section, and a suction section. The conveying section transports the solar cells. The unloading section includes a buffer box carrier device, which holds the buffer boxes containing the solar cells. The suction section includes a suction cup assembly, a lifting drive mechanism that drives the suction cup assembly to move up and down, and a translation device that moves the suction cup assembly back and forth between the unloading section and the conveying section.

[0003] During unloading, the conveyor unit transports the battery cells from the previous process. A lifting drive mechanism drives the suction cup assembly downwards, where it picks up the battery cells. After pickup, the assembly moves upwards, and a translation device moves the suction cup assembly horizontally until it reaches above the buffer box. The lifting drive mechanism then drives the suction cup assembly downwards again, stopping the suction and allowing the cells to be placed into the buffer box. Each buffer box typically holds 200 battery cells. When a buffer box is full, it needs to be moved away, and empty boxes should be replenished promptly. Currently, a robotic arm handles full buffer boxes, while empty boxes are manually placed. If a robotic arm were used for this purpose as well, a mismatch between the replenishment of empty boxes and the placement of battery cells could occur. The suction cup assembly would need to pause for a period while waiting for empty boxes to be placed, severely impacting production efficiency. Utility Model Content

[0025] like Figure 1 and Figure 2As shown, the embodiment relates to a solar cell unloading device, which cooperates with a buffer box and includes: a solar cell transport assembly 10 and a buffer box replenishment assembly 20. The solar cell transport assembly 10 includes a solar cell transfer structure 11 and a solar cell conveying section 12, with the solar cell conveying section 12 located below the solar cell transfer structure 11. The buffer box replenishment assembly 20 includes a translation section 21, a support structure 22, and an empty buffer box conveying section 23. The translation section 21 is located below the support structure 22 and the empty buffer box conveying section 23. The support structure 22 includes a support column 221 and a support plate 222. The support column 221 is disposed on the translation section 21, and the support plate 222 is disposed on the support column 221. The solar cell unloading device has an empty buffer box replenishment state corresponding to the support plate 222 and the empty buffer box conveying section 23, or a solar cell placement state corresponding to the support plate 222 and the solar cell transfer structure 11.

[0026] Applying the technical solution of this embodiment, the cell unloading device and the buffer box 100 cooperate with each other. The cell unloading device includes: a cell transport assembly 10 and a buffer box replenishment assembly 20. The cell transport assembly 10 includes a cell transfer structure 11 and a cell conveying section 12. The cell conveying section 12 is located below the cell transfer structure 11 and is used to transport cells. The cell transfer structure 11 is used to transfer the cells on the cell conveying section 12 to the buffer box 100. The buffer box replenishment assembly 20 includes a translation section 21, a support structure 22, and an empty buffer box conveying section 23. The translation section 21 is located below the support structure 22 and the empty buffer box conveying section 23. The support structure 22 includes a support column 221 and a support plate 222. The support column 221 is disposed on the translation section 21 and can move under the drive of the translation section 21. The support plate 222 is disposed on the support column 221 and is used to place the buffer box 100. The cell feeding device has an empty buffer box replenishment state corresponding to the support plate 222 and the empty buffer box conveying unit 23, in which the empty buffer box is conveyed onto the support plate 222. The cell feeding device also has a cell placement state corresponding to the support plate 222 and the cell transfer structure 11. In this state, the translation unit 21 moves the support plate 222, causing the empty buffer boxes on the support plate 222 to align with the cell transfer structure 11, thus achieving timely replenishment of the empty buffer boxes. Then, the cells are placed into the buffer box 100. The technical solution of this embodiment effectively solves the problem of the buffer box 100 not being replenished in a timely manner in the prior art.

[0027] like Figure 2As shown, in some embodiments, the support structure 22 further includes a reinforcing plate 223, which is disposed on the translation part 21. The support column 221 is a first lifting cylinder, the bottom surface of the cylinder body of the first lifting cylinder is connected to the translation part 21, the side surface of the cylinder body of the first lifting cylinder is connected to the reinforcing plate 223, and the piston rod of the first lifting cylinder is connected to the support plate 222. The first lifting cylinder can drive the support plate 222 to move up and down.

[0028] It should be noted that the support structure 22 also includes a limiting rod, which is set at one end of the support plate 222 away from the empty buffer box conveying part 23. The limiting rod can limit the empty buffer box and prevent it from falling.

[0029] like Figure 2 As shown, in some embodiments, the cache box replenishment assembly 20 further includes a cache box positioning platform 24. The cache box positioning platform 24 has an opening in the middle. When the battery cells are placed, the support structure 22 is located below the cache box positioning platform 24, and the support plate 222 is located inside the opening. The lifting and lowering of the first lifting cylinder realizes the feeding of empty cache boxes and the delivery of full cache boxes (i.e., cache boxes filled with battery cells). The cache box positioning platform 24 can play a positioning role for the movement of the translation part 21 and the lifting and lowering of the support column 221.

[0030] It should be noted that the buffer box positioning platform 24 has a side plate and a bottom plate. An opening is made in the bottom plate, and the side plate is set on the bottom plate. In this embodiment, a mechanical claw is provided on one side of the buffer box positioning platform 24. After the first lifting cylinder descends to the required position, the mechanical claw removes the full buffer box.

[0031] It should also be noted that an ejection cylinder can be installed on the side plate, and a conveyor belt can be installed on the side opposite to the ejection cylinder. The ejection cylinder pushes the full buffer box onto the conveyor belt, and then the first lifting cylinder descends. Driven by the translation part 21, the empty support plate 222 moves to the corresponding position of the empty buffer box conveying part 23, and the empty buffer box is placed on the support plate 222.

[0032] like Figure 1As shown, in some embodiments, the cell transfer structure 11 includes a mounting bracket 111, a first mounting plate 112, a drive motor 113, a drive screw 114, a bearing seat 115, a nut seat 116, and a second mounting plate 117. The first mounting plate 112 is connected to the mounting bracket 111. The drive motor 113 is mounted on the first mounting plate 112. The drive motor 113 is connected to the first end of the drive screw 114. The second end of the drive screw 114 is disposed in the bearing seat 115. The bearing seat 115 is fixed on the first mounting plate 112. The drive motor 113 provides driving force to the drive screw 114 to achieve rotation of the drive screw 114. The nut seat 116 is rotatably disposed on the drive screw 114. The second mounting plate 117 is fixed on the nut seat 116. The nut seat 116 moves along the axial direction of the drive screw 114 as the drive screw 114 rotates. The second mounting plate 117 moves synchronously with the movement of the nut seat 116.

[0033] It should be noted that the cell transfer structure also includes a speed reducer, which is set between the drive motor 113 and the drive screw 114, so that the drive motor 113 and the drive screw 114 are set perpendicularly, reducing the overrun of the drive motor 113.

[0034] In some embodiments, the second mounting plate 117 has a sliding protrusion, and the first mounting plate 112 is provided with a groove. The sliding protrusion is movably disposed in the groove. This arrangement can limit the rotation of the nut seat 116 and the second mounting plate 117.

[0035] like Figure 1 As shown, in some embodiments, the battery cell transfer structure 11 further includes a second lifting cylinder 118 and a transfer suction cup 119. The second lifting cylinder 118 is mounted on the second mounting plate 117. The transfer suction cup 119 is connected to the piston rod of the second lifting cylinder 118, and the second lifting cylinder 118 drives the transfer suction cup 119 to adjust its height. The transfer suction cup 119 is connected to an external negative pressure generator to control the adsorption force of the transfer suction cup 119.

[0036] In some embodiments, the cell transfer structure 11 further includes a limit switch, which is disposed on the first mounting plate 112 and electrically connected to the drive motor 113. When the nut seat 116 moves to contact the limit switch, the drive motor 113 no longer provides driving force, and the movement of the nut seat 116 stops. At this time, the transfer suction cup 119 corresponds to the opening, that is, it corresponds to the empty buffer box on the support plate 222 at the opening, and the cell is placed into the empty buffer box.

[0037] In some embodiments, the support structure 22 further includes a weighing sensor, which is disposed on the support plate 222. As the empty buffer box is gradually filled with battery cells, the change in weight is accurately detected by the weighing sensor.

[0038] The battery cell unloading device also includes a PLC controller. The weighing sensor can transmit signals to the PLC controller. The PLC controller controls the first lifting cylinder to move the support plate 222 and the full buffer box on the support plate 222 downwards. The mechanical claw then transfers the full buffer box.

[0039] The specific working process of this embodiment is as follows: The battery cell conveying unit 12 conveys the battery cells to the area below the transfer suction cup 119. The second lifting cylinder 118 drives the transfer suction cup 119 to move downward, thereby adsorbing the battery cells. The nut seat 116 drives the second mounting plate 117 and the second lifting cylinder 118 and transfer suction cup 119 mounted on the second mounting plate 117 to move synchronously. At this time, the battery cells are in the placement state, the support plate 222 corresponds to the transfer suction cup 119, the transfer suction cup 119 stops adsorbing, and the battery cells are placed into the empty buffer box on the support plate 222. As the empty buffer box gradually fills up, the weighing sensor detects the weight. The change transmits the signal to the PLC controller, which controls the second lifting cylinder 118 to move downward. At this time, the full buffer box is removed from the buffer box positioning platform 24, and the mechanical gripper transfers the full buffer box. Then, the translation part 21 drives the support plate 222 to move, so that the support plate 222 and the empty buffer box conveying part 23 correspond. The new empty buffer box is placed on the support plate 222, and at this time, it is in the empty buffer box replenishment state. Then, the translation part 21 drives the support plate and the empty buffer box on it to be moved below the buffer box positioning platform 24 again, and the first lifting cylinder drives the support plate 222 to move upward, and the empty buffer box is replenished.

[0040] In some embodiments, the translation part 21 is a transverse cylinder, a hydraulic cylinder, or a lead screw structure.

[0041] In some embodiments, the empty buffer box conveying section 23 and the battery cell conveying section 12 are belt conveyors or roller conveyors.
