Description

Technical Field

[0001] The utility model belongs to the technical field of solar cell chips, and in particular relates to a turnover mechanism for a solar cell chip string welding machine. Background Art

[0002] Solar cells need to be clamped and fixed during manufacturing, and need to be turned over for comprehensive processing during processing. In order to ensure the stability of the clamping, the existing fixing method generally uses bolts and other means to firmly clamp them. However, in this case, it is inconvenient to remove the solar cell, and it cannot be turned over and fully processed with high efficiency.

[0003] The existing patent (application number: CN202123095243.2) proposes a flipping device for a solar cell string welding machine, including a shell, a circular opening is provided at the top of one side of the shell, and the shell is rotatably connected to a rotating rod at the circular opening, and one end of the rotating rod inside the shell is fixedly connected to a fixed frame, a cavity is provided inside the fixed frame, and a second opening is provided at the four inner corners of the fixed frame, and the fixed frame is fixedly connected to sleeves at the four second openings, and one end of the four sleeves is provided with a second through hole, and the four sleeves are provided with a fixing rod at the four second through holes. By setting up a fixing frame, the solar cell can be placed inside the fixing frame when processing it, and the solar cell can be clamped and fixed by using the four clamps to approach each other, and when removing the solar cell, it is only necessary to twist the bolts in the opposite direction to make the four clamps move away from each other, so as to make the disassembly and assembly of the solar cell more convenient;

[0004] The pallet holds up and supports the solar cell. When the solar cell needs to be flipped, the staff needs to pull the connecting rod to move the pallet away from the solar cell before flipping the solar cell. If the staff accidentally slips while pulling the connecting rod, causing the connecting rod to fall off their hands, the pallet will instantly rebound due to the elasticity of the pressure spring, which may cause the pallet to hit the solar cell and cause the solar cell to loosen.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0030] In actual use of an existing flipping device for a solar cell string welding machine, the support plate plays a role of lifting and supporting the solar cell. When the solar cell needs to be flipped, the staff needs to pull the connecting rod to make the support plate away from the solar cell before flipping the solar cell. If the staff accidentally slips while pulling the connecting rod and causes the connecting rod to fall off, the support plate will instantly rebound due to the elasticity of the pressure spring, which may cause the support plate to hit the solar cell and cause the solar cell to loosen.

[0031] like Figures 1 to 4 The utility model provides a flipping mechanism for a solar cell string welding machine.

[0032] Specifically, by Figure 1-2A flipping mechanism for a solar cell string welding machine is provided, comprising a workbench 1 and a flipping assembly 2, wherein the flipping assembly 2 is provided in two and is located on the top of the workbench 1, and is used for fixing the solar cell and flipping it at the same time, the flipping assembly 2 comprises a fixed block 201 located on the top of the workbench 1, a servo motor 202 is installed on the inner bottom wall of the fixed block 201, a connecting rod 203 is connected to the driving end of the servo motor 202, an outer wall of the fixed block 201 is rotatably connected to a rotating rod 204, a transmission belt 205 is transmission-connected between one end of the connecting rod 203 extending to the outside of the fixed block 201 and the rotating rod 204, and a clamping block 206 is connected to one end of the rotating rod 204 away from the fixed block 201.

[0033] In the utility model, the solar cell is placed between two clamping blocks 206, and the two clamping blocks 206 are used to clamp and fix the two sides of the solar cell. When the solar cell needs to be flipped, the fixing block 201 supports the connecting rod 203 and the rotating rod 204. The connecting rod 203 is driven to rotate by the servo motor 202. When the connecting rod 203 rotates, the rotating rod 204 is driven to rotate together through the transmission belt 205. When the rotating rod 204 rotates, the clamping block 206 is driven to rotate along with the rotating rod 204. The clamping block 206 drives the solar cell to rotate along the rotating rod 204, and the solar cell is fixed while being flipped, so as to better perform the welding operation and improve the welding quality and efficiency.

[0034] Furthermore, as a specific implementation of the utility model, the utility model provides a flipping mechanism for a solar cell string welding machine.

[0035] Specifically, Figure 1 It is shown that a partition 3 is installed on the top of the workbench 1, a bidirectional screw 4 is threadedly connected between the workbench 1 and the partition 3, a variable current motor 5 is arranged on the top of the workbench 1, a driving end of the variable current motor 5 is connected to one end of the bidirectional screw 4, two fixed blocks 201 are both threadedly connected to the outer wall of the bidirectional screw 4, a sliding rod 6 is connected between the workbench 1 and the partition 3, and the two fixed blocks 201 are both slidably connected to the outer wall of the sliding rod 6.

[0036] In the utility model, the partition 3 supports the bidirectional screw rod 4 and the sliding rod 6. The bidirectional screw rod 4 is driven to rotate by the inverter motor 5. The rotating bidirectional screw rod 4 causes the two flipping components 2 to move relative to each other along the outer wall of the bidirectional screw rod 4. The two clamping blocks 206 move relative to each other to clamp the solar cell in the middle, which is convenient for fixing both sides thereof. The flipping component 2 moves along the outer wall of the bidirectional screw rod 4 and slides along the outer wall of the sliding rod 6. The sliding rod 6 plays a guiding and supporting role, making the flipping component 2 more stable when moving and keeping the flipping component 2 in a parallel state when moving.

[0037] Furthermore, as another specific implementation of the utility model, the utility model provides a flipping mechanism for a solar cell string welding machine.

[0038] Specifically, Figure 1 and 3 It is shown that the inner top wall of the clamping block 206 is connected to two springs 7, the bottom end of the spring 7 is connected to a pressure plate 8, the pressure plate 8 and the spring 7 are both located inside the clamping block 206, and the pressure plate 8 is slidably connected to the inner wall of the clamping block 206.

[0039] In the utility model, when the solar cell is placed between the two clamping blocks 206 for clamping and fixing, the solar cell is located below the pressure plate 8, and the pressure plate 8 is pressed down by the elastic force of the spring 7 so that the pressure plate 8 is against the top of the solar cell, and the solar cell is clamped between the pressure plate 8 and the clamping blocks 206 by the pressure plate 8, so that the solar cell will not easily loosen.

[0040] Furthermore, as another specific implementation of the utility model, the utility model provides a flipping mechanism for a solar cell string welding machine.

[0041] Specifically, Figure 1-2 It is shown that the outer walls of the two connecting rods 203 are connected to the limiting ring 11 . The limiting ring 11 is located on one side of the fixed block 201 . The limiting ring 11 is located below the rotating rod 204 and close to the outer wall of the transmission belt 205 .

[0042] In the present invention, the transmission belt 205 is limited by the limiting ring 11, so that the transmission belt 205 will not easily slip off the outer wall of the connecting rod 203 when it surrounds the outer wall of the connecting rod 203, making the transmission belt 205 more stable and less likely to slip when rotating.

[0043] Furthermore, as another specific implementation of the utility model, the utility model provides a flipping mechanism for a solar cell string welding machine.

[0044] Specifically, Figure 1 It is shown that support blocks are installed on the top of the workbench 1 and the inner bottom wall of the fixed block 201, the inverter motor 5 and the servo motor 202 are both located on the top of the support blocks, and the outer walls of the inverter motor 5 and the servo motor 202 are connected with fixing belts, which are connected to the support blocks.

[0045] In the utility model, the inverter motor 5 and the servo motor 202 are unstable during operation. The support block plays a role of fixing and supporting the inverter motor 5 and the servo motor 202, and the inverter motor 5 and the servo motor 202 are fixed together with the support block by a fixing belt, so that the inverter motor 5 and the servo motor 202 are more stable during operation.

[0046] Furthermore, as another specific implementation of the utility model, the utility model provides a flipping mechanism for a solar cell string welding machine.

[0047] Specifically, Figure 1 and 4 It is shown that two balls 12 are connected to the bottom of the two fixed blocks 201 , and two slide rails 10 adapted to the balls 12 are provided on the top of the workbench 1 . The balls 12 are located inside the slide rails 10 and are slidably connected to the slide rails 10 .

[0048] In the utility model, when the fixed block 201 moves along the top of the workbench 1, the sliding of the ball 12 and the slide rail 10 makes the fixed block 201 move more smoothly, and prevents wear between the fixed block 201 and the workbench 1 due to friction, thereby increasing the service life of the fixed block 201.

[0049] Furthermore, as another specific implementation of the utility model, the utility model provides a flipping mechanism for a solar cell string welding machine.

[0050] Specifically, Figure 1 It is shown that two triangular brackets 9 are installed at the bottom of the workbench 1, and the outer walls of the two triangular brackets 9 are both provided with foot pads. The foot pads are located at the bottom of the triangular brackets 9 and are in direct contact with the ground. The two triangular brackets 9 correspond to the foot pads.

[0051] In the utility model, the triangular bracket 9 supports the workbench 1, making the workbench 1 more stable. The triangular bracket 9 itself has higher stability, making the workbench 1 more secure and supportive. The foot pad is located at the bottom of the triangular bracket 9 to reduce the wear caused by direct contact between the triangular bracket 9 and the ground.

[0052] Working principle:

[0053] The solar cell is placed between the two clamping blocks 206, and the two clamping blocks 206 are used to clamp and fix the two sides of the solar cell. When the solar cell needs to be flipped, the fixing block 201 supports the connecting rod 203 and the rotating rod 204. The connecting rod 203 is driven to rotate by the servo motor 202. When the connecting rod 203 rotates, the rotating rod 204 is driven to rotate together through the transmission belt 205. When the rotating rod 204 rotates, the clamping block 206 is driven to rotate along with the rotating rod 204. The clamping block 206 drives the solar cell to rotate along the rotating rod 204, and the solar cell is fixed and flipped at the same time, so as to better perform the welding operation and improve the welding quality and efficiency.

[0054] The partition 3 supports the bidirectional screw rod 4 and the sliding rod 6. The bidirectional screw rod 4 is driven to rotate by the inverter motor 5. The rotating bidirectional screw rod 4 causes the two flipping components 2 to move relative to each other along the outer wall of the bidirectional screw rod 4. The two clamping blocks 206 move relative to each other to clamp the solar cell in the middle, which is convenient for fixing both sides. The flipping component 2 moves along the outer wall of the bidirectional screw rod 4 and slides along the outer wall of the sliding rod 6. The sliding rod 6 plays a guiding and supporting role, making the flipping component 2 more stable when moving and keeping the flipping component 2 in a parallel state when moving.
