Description

Technical Field

[0001] This invention belongs to the field of battery cell handling technology, specifically a TOPcon battery cell handling support device. Background Technology

[0002] TOPcon solar cells are a high-efficiency solar cell technology based on N-type silicon substrates. Its core lies in achieving excellent passivation through a combination of ultra-thin silicon oxide layers and doped silicon layers. The back passivation contact structure significantly reduces carrier recombination losses. At the same time, it is compatible with existing PERC production line equipment and has industrialization advantages. During the processing of these cells, a handling device is required to support the cells and achieve the desired handling effect.

[0003] For example, the invention disclosed in CN105810619B is a cell rotation transport mechanism with higher handling efficiency, lower cost, more compact structure, and the ability to achieve efficient and accurate switching between two transmission lines. This invention includes a frame, a rotating mechanism mounted on the frame, and a transport mechanism positioned below the rotating mechanism. The transport mechanism includes a rotating beam connected to the rotating mechanism, and suction cup devices are mounted at both ends of the rotating beam via telescopic cylinders.

[0004] In existing technologies, TOPcon battery cells can be adsorbed by setting up suction cups. The soft suction cup structure can effectively avoid damage to the battery cells caused by hard contact. However, the existing structure cannot be flexibly adjusted according to different battery cell sizes. Furthermore, when pressing down, the limited range of deformation of the suction cup structure can easily lead to damage to the battery cells due to excessive pressure.

[0005] Therefore, a TOPcon cell handling support device is proposed to solve the problems mentioned in the background art. Summary of the Invention

The sliding frame is slidably disposed on the outer side of the limiting bracket, and a through hole is opened in the middle of the sliding frame. The adsorption column is movably disposed on the inner side of the through hole.

[0011] Preferably, the sliding frame is rotatably provided with flip-up arc plates on both sides of the end away from the fixed plate, and auxiliary rollers are rotatably provided on both sides of the lower end of the flip-up arc plates. A support platform is installed above the auxiliary rollers and is fixedly connected to the flip-up arc plates. Stop blocks are installed on both sides of the sliding frame and are located on the side of the flip-up arc plates closer to the fixed plate.

[0012] Preferably, the sliding frame is rotatably provided with flip sleeves on both sides near the fixed plate, and a connecting line is installed on one side of the flip sleeve, the connecting line being movably disposed in the middle of the flip arc plate.

[0013] Preferably, a limiting cylinder is installed on the side of the flipping arc plate away from the flipping sleeve, and a supporting spring is provided on the inner side of the limiting cylinder. A movable disc is installed on the end of the connecting line away from the flipping sleeve, and the movable disc is movably disposed on the inner side of the limiting cylinder.

[0014] Preferably, the top of the fixing plate is equipped with six sets of stabilizing plates, and the top of the stabilizing plates is equipped with a set of welding plates. Four sets of support plates are welded and installed on the outside of the welding plates, and auxiliary guide rods are fixedly installed on the top of the support plates. Two sets of limiting grooves are opened on the inner side of the limiting bracket, and the guide slider is slidably arranged on the inner side of the limiting groove.

[0015] Preferably, a telescopic rod is fixedly installed on the top of the welding plate by bolts, and a telescopic push rod is provided at the input end of the telescopic rod. Four sets of limiting plates are welded and installed on the outer side of the telescopic push rod, and the auxiliary guide rod is slidably arranged on the inner side of the limiting plate.

[0016] Preferably, a lateral adjustment block is fixed to the outer side of the upper end of the telescopic push rod by bolts, and a set of adjustment screws is movably arranged on the inner side of the upper end of the lateral adjustment block.

[0017] Preferably, a servo motor is provided at the input end of the adjusting screw, a fixed frame is provided on the outer side of both ends of the adjusting screw, and two sets of stabilizing guide rods are installed on the inner side of the lower end of the fixed frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordination of adjustment components and a fixing plate, facilitates the lateral sliding adjustment of the outer suction structures along the limiting bracket via the central adjustment structure. During adjustment, the distance between the suction cup structure and the central fixing plate can be changed, thereby adjusting the suction size as needed. Simultaneously, a fixed spring, in conjunction with the suction column, slides up and down along the inner side of the adjustment slider to provide auxiliary buffering, preventing excessive pressure that could damage the battery cells. An adjustment screw can move the adjustment sleeve up and down to adjust its position, and the rotating drive frames on the outer sides can push and pull the adjustment slider along the limiting bracket to adjust the position of the bottom suction cup. This allows for changing the suction cup's ability to adsorb different sizes of TOPcon battery structures, achieving flexible adjustment and using the fixed spring to push the suction column back to its original position, while also preventing excessive pressure that could damage the battery cells.

[0019] This invention, through the combination of anti-detachment components and adjustment components, effectively prevents the battery cells from falling off and causing economic losses when the suction cup loses suction force or is damaged. The sliding frame with synchronous sliding adjustment provides an installation position for the outer structure. When the flip plate flips, the support platform is parallel to the battery cell. When the suction cup loses suction force, the support platform provides support for the battery cell. The limiting cylinder restricts the inner support spring, which pushes the movable disc to slide outward along the limiting cylinder. During this sliding process, the connecting line pulls the flip plate clockwise, causing the support platform to automatically reset and move to the bottom of the battery cell during lifting, thus preventing the battery cell from falling off.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 8As shown, the present invention provides a TOPcon battery cell handling support device, including a fixing plate 100, and an adjustment component 001 is provided on the outer side of the fixing plate 100; The adjustment assembly 001 includes an adjustment screw 202, and an adjustment sleeve 203 is slidably disposed on the outer side of the adjustment screw 202. Eight sets of limiting plates 204 are welded and installed on the outer side of the adjustment sleeve 203. A drive frame 200 is rotatably disposed on the inner side of two sets of limiting plates 204. A combination plate 302 is rotatably disposed on the outer side of the drive frame 200 away from the limiting plates 204. An adjustment slider 301 is fixedly installed at the bottom of the combination plate 302. Four sets of limiting brackets 101 are welded and installed on the outer side of the fixed plate 100. The adjustment slider 301 is slidably disposed on the inner side of the limiting brackets 101. An adsorption column 304 is movably disposed on the inner side of the adjustment slider 301. A suction cup 300 is installed at the lower end of the adsorption column 304. A fixing spring 307 is disposed on the outer side of the adsorption column 304.

[0024] An adjusting motor 201 is fixedly installed at the input end of the adjusting screw 202, and the adjusting motor 201 is embedded in the middle of the fixed plate 100.

[0025] Two sets of combination plates 302 are welded and installed on the top of the adjusting slider 301. The drive frame 200 is rotatably set inside the combination plate 302. Guide sliders 303 are installed on the front and back of the adjusting slider 301. A fixing ring 306 is installed on the outer side of the middle part of the adsorption column 304, and the fixing ring 306 is movably set on the top of the adjusting slider 301. A connecting hose 305 is installed on the top of the adsorption column 304.

[0026] The above scheme is adopted as follows: During the rotation of the adjusting screw 202, the threaded structure drives the adjusting screw sleeve 203 to slide up and down for adjustment. The limiting plate 204 can restrict the inner drive frame 200. The drive frame 200 can push the adjusting slider 301 at the end to slide along the inner side of the limiting bracket 101 for adjustment. The guide slider 303 can slide laterally along the inner side of the limiting slide groove 102, which can effectively maintain the stability of the sliding of the adjusting slider 301. The adjusting motor 201 can provide rotational kinetic energy for the adjusting screw 202 to ensure that the adjusting component 001 can operate normally. The suction column 304 can connect the bottom suction cup 300 and the connecting hose 305. The connecting hose 305 can connect to the external suction drive device to ensure that the suction cup 300 can normally adsorb the battery cell. The combination plate 302 can restrict the other end of the drive frame 200 to ensure that the drive frame 200 can normally push and change the position of the adjusting slider 301.

[0027] like Figure 5 and Figure 6As shown, an anti-detachment component 002 is slidably installed on the outer side of the adsorption column 304, and the anti-detachment component 002 includes a sliding frame 401. The sliding frame 401 is slidably disposed on the outer side of the limiting bracket 101. A through hole 402 is opened in the middle of the sliding frame 401, and the adsorption column 304 is movably disposed on the inner side of the through hole 402.

[0028] The sliding frame 401 has a rotating arc plate 404 on both sides of the end away from the fixed plate 100, and auxiliary rollers 405 are rotatably installed on both sides of the lower end of the rotating arc plate 404. A support platform 400 is installed above the auxiliary rollers 405, and the support platform 400 is fixedly connected to the rotating arc plate 404. Stop blocks 403 are installed on both sides of the sliding frame 401, and the stop blocks 403 are located on the side of the rotating arc plate 404 closer to the fixed plate 100.

[0029] The sliding frame 401 has a flip sleeve 501 rotatably mounted on both sides of the end near the fixed plate 100, and a connecting line 502 is installed on one side of the flip sleeve 501. The connecting line 502 is movably mounted in the middle of the flip arc plate 404.

[0030] A limiting cylinder 503 is installed on the side of the flipping arc plate 404 away from the flipping sleeve 501, and a support spring 504 is provided on the inner side of the limiting cylinder 503. A movable disc 500 is installed on the end of the connecting line 502 away from the flipping sleeve 501, and the movable disc 500 is movably disposed on the inner side of the limiting cylinder 503.

[0031] Using the above scheme: the sliding frame 401 is connected to the adsorption column 304. After connection, the anti-detachment component 002 can be adjusted synchronously under the push of the adjusting slider 301. The flipping arc plate 404 can be flipped along the axis connected to the sliding frame 401 at the upper end. The support platform 400 can provide support for the fallen battery panel. The auxiliary roller 405 contacts the worktable when the device is pressed down. The auxiliary roller 405 assists in pushing the flipping arc plate 404 to flip and extend outward. The limiting cylinder 503 can provide an installation position for the inner support spring 504. The support spring 504 can cooperate with the movable plate 500 to push the flipping arc plate 404 to flip clockwise. The connecting line 502 is connected to the flipping sleeve 501 to ensure that the position of the movable plate 500 is fixed. At the same time, it can slide along the inner side of the limiting cylinder 503 to ensure that the flipping arc plate 404 can be reset. The support platform 400 provides support for the battery panel.

[0032] like Figure 1 , Figure 7 and Figure 8As shown, six sets of stabilizing plates 103 are installed on the top of the fixed plate 100, and a set of welding plates 104 are installed on the top of the stabilizing plates 103. Four sets of support plates 105 are welded and installed on the outer side of the welding plates 104, and auxiliary guide rods 106 are fixedly installed on the top of the support plates 105. Two sets of limiting grooves 102 are opened on the inner side of the limiting bracket 101, and the guide slider 303 is slidably arranged on the inner side of the limiting groove 102.

[0033] A telescopic rod 602 is fixedly installed on the top of the welding plate 104 by bolts, and a telescopic push rod 600 is provided at the input end of the telescopic rod 602. Four sets of limiting plates 601 are welded and installed on the outside of the telescopic push rod 600, and the auxiliary guide rod 106 is slidably arranged on the inside of the limiting plate 601.

[0034] A transverse adjustment block 603 is fixed to the outer side of the upper end of the telescopic push rod 600 by bolts, and a set of adjustment screws 703 is movably arranged on the inner side of the upper end of the transverse adjustment block 603.

[0035] The input end of the adjusting screw 703 is equipped with a servo motor 702. The outer sides of both ends of the adjusting screw 703 are equipped with a fixed frame 701, and two sets of stabilizing guide rods 700 are installed on the inner side of the lower end of the fixed frame 701. The stabilizing guide rods 700 are movably arranged on the inner side of the lower end of the horizontal adjusting block 603.

[0036] The above solution utilizes a stabilizing plate 103 to securely connect the fixing plate 100 and the top welding plate 104, maintaining structural stability. A support plate 105 provides support for the top auxiliary guide rod 106. Combined with the upper limiting plate 204, this increases the stability of the lower structure's vertical sliding adjustment. The telescopic push rod 600, connected to an external controller, drives the output telescopic rod 602 and the overall bottom structure to move vertically. The fixing frame 701 connects to an external bracket. A drive servo motor 702 rotates the adjusting screw 703, which, during rotation, uses a threaded structure to drive the lateral adjusting block 603 to slide laterally, thereby changing the position of the overall bottom structure and facilitating the movement of battery cells. The stabilizing guide rod 700 effectively increases the stability of the lateral adjusting block 603's sliding adjustment.

[0037] The working principle and usage process of this invention are as follows: First, the servo motor 702 drives the adjusting screw 703 to rotate, which in turn drives the adjusting horizontal adjusting block 603 to adjust its position. Then, the telescopic push rod 600 drives the welding plate 104 at the bottom to adjust its height. During the adjustment process, each set of auxiliary rollers 405 will first contact the worktable. When the pressure is continuously applied, the auxiliary rollers 405 will roll outward, thereby assisting the flipping arc plate 404 to flip along the upper axis. During the continuous pressure, the suction cup 300 will contact the battery cell and adsorb the battery cell through adsorption force. During the lifting process, the fixing spring 307 will push the suction cup 300 to reset, and at the same time, the auxiliary rollers 405 will separate from the worktable. Under the pushing action of the support spring 504, the moving plate 500 pushes the flipping arc plate 404 to reset and contact the stop block 403, keeping the support platform 400 parallel to the bottom of the battery cell. During adjustment, the adjusting screw 202 is rotated by the adjusting motor 201. The rotation uses the threaded structure to drive the adjusting screw sleeve 203 to slide up and down. During the adjustment process, the four sets of drive frames 200 on the outside will push the adjusting slider 301 to slide along the inner side of the limiting slide groove 102, thereby adjusting the position of the suction cup 300.
