Description

Technical Field

[0001] This utility model relates to the technical field of solar cell handling devices, specifically to a photovoltaic solar cell handling device that facilitates stacking. Background Technology

[0002] The solar cell is the most crucial component of a photovoltaic (PV) module, and its structure directly affects the module's conversion efficiency. N-type TOPCon PV cells are a high-efficiency solar cell technology based on the selective carrier principle and tunneling oxide layer passivation contacts. An ultra-thin silicon oxide layer is fabricated on the back of the cell, followed by the deposition of a thin doped silicon layer. These two layers together form a passivation contact structure, effectively reducing the probability of surface recombination and emitter-metal contact recombination, increasing the open-circuit voltage of the solar cell, and thus improving its conversion efficiency.

[0003] A search revealed an invention patent with publication number CN119092453B, which discloses a photovoltaic cell adsorption and handling device. This invention solves the problem of photovoltaic cells being easily damaged during handling due to the lack of a buffer and guiding structure. The device, through the arrangement of the handling mechanism, after the photovoltaic cell is adsorbed and fixed, moves the connecting plate upwards, pressing against the bottom surface of the baffle and causing the baffle to rotate. This allows two sets of movable plates to move closer together, using a buffer roller to limit and fix the photovoltaic cell. Magnetic plates A and B repel each other, strengthening the fixation. Simultaneously, when the photovoltaic cell abuts against the abutment plate, a pressure sensor contacts the pressure plate, stopping the connecting plate from moving upwards. When placing the photovoltaic cell subsequently, it slides downwards along the buffer roller, providing a buffering and guiding effect, thus achieving the purpose of buffering and guiding protection during the placement of the adsorbed photovoltaic cell.

[0004] Although the aforementioned patent achieves the purpose of buffering and guiding photovoltaic cells by having them slide down along the soft roller, thus protecting them during placement, existing cells require handling and stacking after production to reduce storage space. The device in the aforementioned patent can only use suction cups to pick up and move the cells, requiring them to be stacked one by one, which reduces the efficiency of cell stacking.

[0005] Therefore, it is necessary to propose a photovoltaic cell handling device that facilitates stacking to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a photovoltaic cell handling device that facilitates stacking. Through the cooperation between the internal parts of the stacking mechanism, the cells can be stacked between the base plate and the fixed plate. It also facilitates the pusher plate to move the stacked cells to a suitable storage location. This solves the problem in the prior art where the device can only use suction cups to pick up and move the cells, which requires stacking the cells one by one and thus reduces the stacking efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic cell handling device for easy stacking, comprising a device body, a conveyor belt placed on the right side of the device body, a moving mechanism installed on the left side of the device body and slidably connected to the bottom end of the device body, and a stacking mechanism installed and fixed at the bottom end of the moving mechanism and located on the left side of the conveyor belt.

[0008] The moving mechanism includes a slide block, which is slidably connected to the bottom end of the device body. A connecting gear is rotatably connected to the bottom end of the slide block, and a rack is installed and fixed at the top end of the device body and located at one end of the outer wall of the connecting gear.

[0009] The stacking mechanism includes a fixed plate, which is mechanically fixed to the bottom end of a connecting gear. Fixed rods are mechanically fixed around the bottom end of the fixed plate. A movable rod is slidably fitted onto the outer wall of the fixed rod. A telescopic spring is mechanically connected between the movable rod and the fixed rod and is fitted onto the outer wall of the fixed rod. A base plate is mechanically connected to the bottom end of the movable rod. An electric telescopic rod is fixed to the side of the base plate away from the conveyor belt via a bracket. A push plate is mechanically fixed to the output end of the telescopic spring and is located between the fixed plate and the base plate.

[0010] Preferably, the moving mechanism further includes a servo motor, which is fixed to the left side of the device body by bolts. The output end of the servo motor is mechanically connected to a threaded rod through a coupling and is rotatably connected to the inside of the device body. The slide block slides with the outer wall of the threaded rod through a threaded connection.

[0011] Preferably, the bottom end of the main body of the device is provided with a sliding groove that matches the slide block, the rack and the connecting gear mesh with each other through the tooth groove, and the connecting gear is rotatably connected to the bottom end of the slide block through a bearing.

[0012] Preferably, the surface of the conveyor belt is provided with a correction roller, and the horizontal height of the conveyor belt is consistent with the horizontal height of the base plate, and a protective plate is installed between the plurality of movable rods.

[0013] Preferably, the movable rod has an internal telescopic space that matches the telescopic spring, and a limit ring is installed at the bottom end of the fixed rod.

[0014] Preferably, the servo motor and the electric telescopic rod are connected to an external power source via cables, and there is a pushing space between the fixed plate and the base plate that matches the push plate, and the surfaces of the push plate and the base plate are made of sponge material.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The conveyor belt is equipped with a correction roller, and the horizontal height of the conveyor belt is consistent with the horizontal height of the base plate. This facilitates the stable transport of the battery cells to the inside of the base plate. After the battery cells are transported to the surface of the base plate, the weight of the base plate changes, which causes the movable rod to compress the telescopic spring and move. This causes the movable rod to slide downward on the outer wall of the fixed rod, and makes the top of the battery cells on the base plate consistent with the horizontal height of the conveyor belt. This facilitates the subsequent stacking of the battery cells on the base plate, thus completing the stacking operation of the battery cells between the base plate and the fixed plate.

[0017] 2. By starting the servo motor, the servo motor drives the threaded rod to rotate, which in turn moves the slide away from the left side of the conveyor belt. At the same time, after the slide moves a certain distance, it drives the connecting gear and the rack to mesh with each other through the tooth grooves. This causes the connecting gear to rotate at the bottom of the slide, which in turn causes the fixed plate and the base plate to rotate 90 degrees to align with the storage position. Finally, the electric telescopic rod pushes the push plate to move, which in turn pushes the stacked battery cells out from between the base plate and the fixed plate. Attached Figure Description

A rack 205 is installed and fixed at the top end of the device body 1 and is located at one end of the outer wall of the connecting gear 204.

[0028] The stacking mechanism 3 includes a fixed plate 301, which is mechanically fixed to the bottom end of the connecting gear 204. Fixed rods 302 are mechanically fixed around the bottom end of the fixed plate 301. A movable rod 303 is slidably sleeved on the outer wall of the fixed rod 302. A telescopic spring 305 is mechanically connected between the movable rod 303 and the fixed rod 302 and is sleeved on the outer wall of the fixed rod 302. A base plate 304 is mechanically connected to the bottom end of the movable rod 303.

A push plate 307 is mechanically fixed to the output end of the telescopic spring 305 and is located between the fixed plate 301 and the base plate 304.

[0029] By cooperating with each other among the internal parts of the moving mechanism 2, the slide 203 can be moved, causing the base plate 304 to move closer to one side of the conveyor belt 101. The fixed plate 301 can be rotated 90 degrees by connecting gear 204 and rack 205. By cooperating with each other among the internal parts of the stacking mechanism 3, the battery cells can be stacked between the base plate 304 and the fixed plate 301, and the pusher plate 307 can push the stacked battery cells to a suitable storage position.

[0030] Refer to the instruction manual appendix Figure 1-4The moving mechanism 2 also includes a servo motor 201, which is fixed to the left side of the main body 1 by bolts. The output end of the servo motor 201 is mechanically connected to a threaded rod 202 through a coupling and is rotatably connected to the inside of the main body 1. The slide 203 slides with the outer wall of the threaded rod 202 through a threaded sleeve. Through the mutual cooperation between the internal parts of the moving mechanism 2, the slide 203 can be driven to move horizontally.

[0031] Refer to the instruction manual appendix Figure 1-4 The bottom end of the main body 1 of the device is provided with a sliding groove that matches the slide 203. The rack 205 and the connecting gear 204 mesh with each other through the tooth groove. The connecting gear 204 is rotatably connected to the bottom end of the slide 203 through a bearing. The sliding groove provided at the bottom end of the main body 1 of the device is provided with a sliding groove that matches the slide 203. The rack 205 and the connecting gear 204 mesh with each other through the tooth groove, which facilitates the movement of the slide 203 to drive the connecting gear 204 and the rack 205 to contact each other, so that the connecting gear 204 can rotate through the meshing of the rack 205.

[0032] Refer to the instruction manual appendix Figure 1-4 The surface of the conveyor belt 101 is provided with a correction roller, and the horizontal height of the conveyor belt 101 is consistent with the horizontal height of the base plate 304. A protective plate is installed between multiple movable rods 303. The correction roller on the surface of the conveyor belt 101 and the horizontal height of the conveyor belt 101 are consistent with the horizontal height of the base plate 304, which facilitates the stable transport of the battery cells to the interior of the base plate 304 by the conveyor belt 101.

[0033] Refer to the instruction manual appendix Figure 1-4 The movable rod 303 has an internal telescopic space that matches the telescopic spring 305, and a limit ring is installed at the bottom end of the fixed rod 302. The movable rod 303 has an internal telescopic space that matches the telescopic spring 305, and the fixed rod 302 has a limit ring at the bottom end, which facilitates the sliding of the movable rod 303 on the outer wall of the fixed rod 302.

[0034] Refer to the instruction manual appendix Figure 1-4 The servo motor 201 and the electric telescopic rod 306 are both connected to an external power source via cables. A pushing space matching the push plate 307 is left between the fixed plate 301 and the base plate 304. The surfaces of the push plate 307 and the base plate 304 are made of sponge material, which facilitates the push plate 307 to push the stacked battery cells out of the base plate 304.

[0035] The working principle of this practical application is as follows:

[0036] Refer to the instruction manual appendix Figure 1-4The conveyor belt 101 has a correction roller on its surface, and the horizontal height of the conveyor belt 101 is consistent with the horizontal height of the base plate 304. This makes it easy for the conveyor belt 101 to stably transport the battery cells into the base plate 304. After the battery cells are transported to the surface of the base plate 304, the weight of the base plate 304 changes, which causes the movable rod 303 to compress the telescopic spring 305 and move. This causes the movable rod 303 to slide downward on the outer wall of the fixed rod 302, and makes the top of the battery cells on the base plate 304 consistent with the horizontal height of the conveyor belt 101. This makes it easier for the battery cells to be stacked on the base plate 304 and the fixed plate 301 to complete the stacking operation of the battery cells.

[0037] Refer to the instruction manual appendix Figure 1-4 By starting the servo motor 201, the servo motor 201 drives the threaded rod 202 to rotate, causing the threaded rod 202 to move the slide 203 away from the left side of the conveyor belt 101 through the thread. At the same time, after the slide 203 moves a certain distance, it drives the connecting gear 204 and the rack 205 to mesh with each other through the tooth groove, thereby causing the connecting gear 204 to rotate at the bottom of the slide 203. The rotation of the connecting gear 204 causes the fixing plate 301 and the base plate 304 to rotate 90 degrees to align with the storage position. Finally, the electric telescopic rod 306 pushes the push plate 307 to move, and the movement of the push plate 307 can push the stacked battery cells out from between the base plate 304 and the fixing plate 301.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
