[0002] Before transportation, solar cells are typically stacked together, with sulfur-free paper, pearl cotton, and hollow fiberboard laid on top and bottom of the stack. The cells are then placed in packaging bags, then sealed in a box before transport. The sulfur-free paper provides some waterproofing and moisture protection, while the hollow fiberboard and pearl cotton offer excellent cushioning and shock absorption, effectively preventing the cells from being damaged by collisions and impacts during transport.

[0003] However, after the solar cells are transported to the photovoltaic workshop, workers need to manually remove the hollow panels, pearl cotton and sulfur-free paper one by one, which is time-consuming, labor-intensive and inefficient. Summary of the Invention

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] like Figures 1 to 3 As shown, this application provides a rejection device for packaging materials, including a fixed clamp 1, a rejection mechanism 2, and a moving mechanism 3. The fixed clamp 1 is fixed on a rejection base 4, and the fixed clamp 1 has a fixed position. The rejection mechanism 2 is located at one end of the fixed clamp 1, and the rejection mechanism 2 includes a rejection suction claw 21 and a suction claw driving assembly 22. The rejection suction claw 21 is connected to the suction claw driving assembly 22, and the suction claw driving assembly 22 controls the opening and closing of the rejection suction claw 21. The moving mechanism 3 includes a lateral moving assembly 31 and a longitudinal moving assembly 32. The longitudinal moving assembly 32 is connected to the lateral moving assembly 31, and the rejection suction claw 21 is connected to the longitudinal moving assembly 32. The lateral moving assembly 31 drives the rejection suction claw 21 to move closer to or further away from the fixed clamp 1, and the longitudinal moving assembly 32 drives the rejection suction claw 21 to rise and fall relative to the fixed clamp 1.

[0021] When using the packaging material rejection device, the battery cell assembly 5 is first placed in a fixed position. Then, the lateral moving component 31 and the longitudinal moving component 32 drive the rejection suction claw 21 to predetermined positions on both sides of the battery cell assembly 5. Next, the suction claw drive component 22 controls the rejection suction claw 21 to close, and the rejection suction claw 21 picks up the hollow panels on both sides. Then, the longitudinal moving component 32 drives the rejection suction claw 21 to move upward, and the lateral moving component 31 drives the rejection suction claw 21 to move, removing the hollow panels from the sides of the battery cell. The removed hollow panels are then conveyed out via an external conveyor belt. Following the same method of removing hollow panels, the pearl cotton and sulfur-free paper are removed in sequence. The packaging material rejection device of this application can automatically remove waste materials such as hollow panels, pearl cotton, and sulfur-free paper from the sides of the battery cells. Compared with manual operation, it not only improves work efficiency but also saves labor costs.

[0022] To secure the battery cell assembly 5 in the fixed position, the fixing fixture 1 includes a fixture fixing plate 11 and two fixture moving plates 12. The fixture fixing plate 11 can be fixed to the top of the removal base 4 by bolts. The two fixture moving plates 12 are arranged opposite to each other, forming a fixed position between the fixture fixing plate 11 and the two fixture moving plates 12. The two fixture moving plates 12 are movably connected to the fixture fixing plate 11, and the two fixture moving plates 12 can move towards or away from each other. Preferably, the fixture moving plates 12 have an L-shaped structure.

[0023] Since the two clamping moving plates 12 can move towards or away from each other, the gap between the two clamping moving plates 12 can be adjusted. To achieve position adjustment of the clamping moving plates 12, an adjustment groove 121 is provided on the clamping moving plates 12 along their width direction. Along the width direction of the clamping fixing plate 11, a plurality of adjustment holes are provided on the clamping fixing plate 11, and the clamping moving plates 12 are movably connected to the clamping fixing plate 11 through the adjustment groove 121 and the adjustment holes.

[0024] Specifically, a bolt can be installed in the adjustment groove 121. One end of the bolt passes through the corresponding adjustment hole and is fixed by a nut, thereby fixing the fixture moving plate 12 on the fixture fixing plate 11. When it is necessary to adjust the position of the fixture moving plate 12, the bolt can be removed from the adjustment hole, and then the fixture moving plate 12 can be moved. After the fixture moving plate 12 moves to the predetermined position, the bolt can be inserted into the corresponding adjustment hole and tightened to fix it.

[0025] This application allows for the adjustment of the position of the clamping moving plate 12 by setting the clamping moving plate 12 to be movably connected to the clamping fixed plate 11, thereby adjusting the gap between the two clamping moving plates 12. This makes it suitable for use with battery cell assemblies 5 of different thicknesses, and has a wide range of applications.

[0026] Because the sides of the solar cells are covered with hollow sheets, pearl cotton and sulfur-free paper, and the solar cell assembly 5 can only limit the lower part of the solar cell assembly 5 after it is placed in the fixed position, the pearl cotton and sulfur-free paper may collapse downwards due to their softness and thinness after the hollow sheets are removed.

[0027] To avoid the aforementioned situation, the fixing clamp 1 further includes two baffles 13, which are respectively connected to two clamp moving plates 12. The baffles 13 protrude upwards from the clamp moving plates 12. The baffles 13 and the clamp moving plates 12 can be connected by screws. After the battery cell assembly 5 is placed in the fixing position, the two baffles 13 can block the upper part of the battery cell assembly 5 for support, preventing the pearl cotton and sulfur-free paper from collapsing due to their softness and thinness after the hollow board is removed.

[0028] However, since the removal suction claw 21 is needed to remove the hollow board, pearl cotton, and sulfur-free paper, in order not to affect the operation of the removal suction claw 21, the removal suction claw 21 is located on the outer side of one end of the clamp fixing plate 11, and the baffle 13 is located on the other end of the clamp fixing plate 11. The arrangement of the baffle 13 and the removal suction claw 21 can ensure that the baffle 13 supports the hollow board, pearl cotton, and sulfur-free paper, while not affecting the removal suction claw 21's removal of the hollow board, pearl cotton, and sulfur-free paper.

[0029] In one embodiment, such as Figure 3 As shown, in order to remove packaging materials (hollow board, pearl cotton and sulfur-free paper), the rejection suction claw 21 includes rejection gripper 211 and suction cup 212. The suction cup 212 is fixed on the rejection gripper 211, and the rejection gripper 211 is connected to the suction claw drive assembly 22.

[0030] Preferably, the lateral movement component 31 is an existing linear module, and the longitudinal movement component 32 is a cylinder. The longitudinal movement component 32 and the lateral movement component 31 are slidably connected by a slider. A cylinder fixing plate 23 can be connected to the output end of the longitudinal movement component 32 by screws, and the suction claw drive component 22 is fixed to the cylinder fixing plate 23 by screws. The suction claw drive component 22 is an existing finger cylinder, and the removal gripper 211 is connected to the piston rod of the finger cylinder by screws, thereby controlling the opening and closing of the removal gripper 211 by the finger cylinder.

[0031] Each rejection gripper 211 can be equipped with two suction cups 212, which can also be screwed onto the rejection gripper 211. Since both sides of the battery cell are covered with hollow board, pearl cotton, and sulfur-free paper, the rejection gripper 211 and suction cups 212 can remove the hollow board, pearl cotton, and sulfur-free paper from both sides of the battery cell simultaneously, improving work efficiency.

[0032] In one embodiment, such asFigure 3 As shown, the rejection mechanism 2 further includes a vertical baffle 24, which is connected to the rejection gripper 211 and protrudes upwards from the rejection gripper 211. The bottom of the vertical baffle 24 can also be fixed to the rejection gripper 211 by screws or by welding. Preferably, two vertical baffles 24 are fixed on each rejection gripper 211, and the two vertical baffles 24 and two suction cups 212 are staggered on the rejection gripper 211. The top of the vertical baffle 24 has an outwardly inclined slope.

[0033] Since the removal claw 21 is located on the outer side of one end of the clamp fixing plate 11, and the baffle 13 is located on the other end of the clamp fixing plate 11, after the hollow plate is removed, the pearl cotton and sulfur-free paper near the removal claw 21 will still flip outwards towards the outside of the battery cell. Therefore, this application provides a vertical baffle 24 on the removal claw 211. When the removal claw 211 is in the open state and the battery cell assembly 5 is located inside it, the outwardly flipped pearl cotton and sulfur-free paper can be supported by the vertical baffle 24. As the removal claw 211 closes, the pearl cotton and sulfur-free paper can be made to stand upright under the action of the vertical baffle 24, and then they can be picked up by the suction cup 212.

[0034] After the hollow board, pearl cotton, and sulfur-free paper are removed sequentially by the suction cup 212, the battery cell assembly needs to be inspected to determine whether the packaging materials have been completely removed. To achieve this inspection, the packaging material removal device also includes two inspection components 6, which are respectively connected to the two clamping moving plates 12.

[0035] Specifically, such as Figure 2 As shown, the detection component 6 includes a detection fixing plate 61 and a sensor 62. The detection fixing plate 61 is fixed to the clamp moving plate 12 by screws, and the sensor 62 is fixed to the detection fixing plate 61 by screws. Preferably, the sensor 62 can be an existing fiber optic sensor. In one embodiment, the sensor 62 can also be an existing reflective optical sensor. A through hole is provided in the baffle 13, and the light emitted by the sensor 62 passes through the through hole. The light emitted by the sensor 62 can be reflected back after contacting the hollow plate, pearl cotton, sulfur-free paper, and battery cell. The difference in the intensity of the reflected light is used to determine the sensor's position.

[0036] In other embodiments, two detection components 6 can be fixed on the same fixture moving plate 12, and the two detection components 6 can perform detection simultaneously, thereby making the judgment result more accurate.

[0037] In one embodiment, such as Figure 1As shown, in order to limit the battery cell assembly 5 placed in the fixed position, the packaging material rejection device also includes a limiting plate 7, which is movably connected to the clamp moving plate 12 and is located at one end of the fixed clamp 1.

[0038] like Figure 2 As shown, to achieve the movable connection between the limiting plate 7 and the clamping moving plate 12, a movable groove 71 can be provided on the limiting plate 7, and multiple connecting holes can be provided at corresponding positions on the clamping moving plate 12. Bolts are installed in the movable groove 71. When one end of the bolt is placed in the corresponding connecting hole and tightened, the limiting plate 7 and the clamping moving plate 12 can be fixed. When the bolt is removed from the connecting hole, the limiting plate 7 can be moved, thereby adjusting the position of the limiting plate 7.

[0039] Once the battery cell assembly 5 is placed in the fixed position, one end of the battery cell assembly 5 can be limited by the limiting plate 7. Since the limiting plate 7 can move relative to the clamping moving plate 12, the position of the limiting plate 7 can be adjusted according to the battery cell of different sizes, thus making it suitable for use with battery cells of different sizes.

[0040] In one embodiment, such as Figure 1 , Figure 2 As shown, the packaging material rejection device also includes a fixed suction cup mechanism 8, located at the other end of the fixed clamp 1. The fixed suction cup mechanism 8 includes a fixed gripper 81, a fixed suction cup 82, and a gripper drive 83. The fixed gripper 81 is connected to the gripper drive 83, and the gripper drive 83 controls the opening and closing of the fixed gripper 81. The fixed suction cup 82 is fixed to the fixed gripper 81.

[0041] Preferably, the gripper drive 83 is a finger cylinder, the fixed gripper 81 is connected to the output end of the finger cylinder by screws, and there are two fixed suction cups 82, which are respectively fixed to the two fixed grippers 81 by screws. The gripper drive 83 can be fixed to the clamp fixing plate 11 by screws.

[0042] In operation, the packaging material rejection device of this application first places the battery cell assembly 5 in a fixed position using external grippers, and supports the hollow board, pearl cotton, and sulfur-free paper using a baffle 13. Then, the lateral movement component 31 and the longitudinal movement component 32 move the rejection gripper 211 to a predetermined position. Next, the suction gripper drive component 22 drives the rejection gripper 211 to close, and the suction cup 212 picks up the hollow board. After picking up the hollow board, the longitudinal movement component 32 moves the suction cup 212 and the hollow board upwards, bringing the hollow board above the limiting plate 7 (or the clamping moving plate 12). Then, the lateral movement component 31 moves the suction cup 212 and the hollow board laterally away from the battery cell, pulling the hollow board out from the side of the battery cell. The suction cup 212 then stops adsorbing the hollow board, allowing it to fall downwards onto the conveyor belt. The conveyor belt, which can be a belt conveyor, transports the hollow board out. Next, following the same method of picking up hollow boards, pick up pearl cotton and sulfur-free paper in sequence, and then convey them out via a conveyor belt.

[0043] During the process of suctioning the hollow board and moving it laterally, the pearl cotton can be fixed in place using the fixing suction cup 82 to prevent it from moving with the hollow board and affecting subsequent pearl cotton adsorption. Similarly, after suctioning the pearl cotton, the sulfur-free paper can be fixed in place using the fixing suction cup 82 to prevent it from moving with the pearl cotton and affecting subsequent sulfuric acid adsorption.

[0044] Both the suction cup 212 and the fixed suction cup 82 in this application achieve adsorption through the principle of vacuum adsorption.
