Description

Technical Field

[0001] This invention relates to the field of photovoltaic module production equipment technology, specifically a photovoltaic module connecting strip switching punching device. Background Technology

[0002] Before lamination, the welding strips and connecting strips of photovoltaic cell strings need to be welded together to form a complete cell circuit. However, the connecting strips have different end structures from different module manufacturers. The mainstream end structures are right-angled ends and rounded ends. Since the connecting strips are rolled up and do not have different end structures, they are strip-shaped. Therefore, different end structures require the connecting strip sorting equipment to cut the connecting strips into different shapes.

[0003] However, current connector production equipment can only cut connectors into preset shapes. When the equipment needs to switch to producing different connectors, the entire machine needs to be shut down for maintenance, the original punching equipment needs to be removed, and a punching equipment of the required shape needs to be installed. Then, it needs to be debugged and tested for several days. This greatly reduces the production cycle and increases production costs. Summary of the Invention

[0004] To address the problems in the prior art, the present invention aims to provide a photovoltaic module connector strip switching and punching device. When photovoltaic module production requires switching of the end structure, no additional disassembly and adjustment work is required, thereby improving the compatibility of connector strip production and finishing equipment and increasing production efficiency.

[0005] A photovoltaic module connecting strip switching punching device includes a lateral moving device, a front-back moving device, and a punching unit. The punching unit is installed at the movable end of the lateral moving device, and the fixed end of the lateral moving device is installed at the movable end of the front-back moving device. The punching unit includes at least two different punching heads.

[0006] Two different punching heads can be used to perform punching operations with two different end structures. When it is necessary to switch the end structure, the transverse moving device is driven to move the punching unit so that the other punching head can work, thus realizing the punching of the new end structure. There is no need to disassemble and adjust the machine, which speeds up production efficiency.

[0007] Meanwhile, by driving the forward and backward moving device, the punching unit can punch the corresponding end structure at different positions of the connecting strip, which enhances the compatibility of the overall structure and improves production efficiency.

[0008] Specifically, the blanking unit includes a blanking power unit, a blanking seat, and at least two different blanking heads disposed in the blanking seat. The movable end of the blanking power unit is fixedly connected to the blanking head, and the blanking power unit drives the blanking head to move within the blanking seat.

[0009] Furthermore, the blanking seat has a through hole relative to the blanking head.

[0010] Preferably, the bottom of the punching seat is provided with a connecting strip through groove, and a through hole vertically passes through the connecting strip through groove.

[0011] By setting the connecting strip through the groove, the horizontal position of the connecting strip is limited within the groove before punching, thus ensuring the punching effect.

[0012] Preferably, an elastic element is provided between the punching seat and the punching power device.

[0013] Furthermore, the elastic element includes a guide post and a rectangular spring. The guide post is connected to the punching power device and passes through the punching seat. The rectangular spring is sleeved on the guide post and abuts against the punching power device and the punching seat.

[0014] By incorporating the elastic element, the connecting strip can be pressed against the blanking seat before blanking. After blanking, the blanking head moves away from the connecting strip first, and then the blanking seat continues to press against the connecting strip under the elastic force. Only when the blanking power device continues to rise will the connecting strip be released, thus improving the stability of the blanking process and further ensuring complete blanking and accurate material cutting.

[0015] Specifically, the punching head includes a round-edge punching head and a straight-edge punching head. The punching seat has an I-shaped hole relative to the round-edge punching head, and the punching seat has a rectangular hole relative to the straight-edge punching head.

[0016] The H-shaped hole effectively completes the punching of the connecting strip, with both ends being round. One punching creates two round ends, and similarly, a rectangular hole creates two right-angled ends in one punching.

[0017] Furthermore, the rectangular holes and the I-shaped holes are arranged along the moving direction of the transverse moving device.

[0018] In summary, two different punching heads can be used to perform punching operations with two different end structures. When it is necessary to switch the end structure, the driving transverse moving device moves the punching unit, allowing the other punching head to work, thus achieving the punching of the new end structure without disassembling and adjusting the machine, thereby accelerating production efficiency. The connecting strip through-slot design ensures the horizontal position of the connecting strip is limited within the slot before punching, guaranteeing the punching effect. The elastic element allows the punching seat to press the connecting strip firmly before punching. After punching, the punching head first moves away from the connecting strip, and then the punching seat continues to press the connecting strip firmly under the elastic force. Only when the punching power device continues to rise does the connecting strip release, improving the stability of the punching process and further ensuring complete punching and accurate material removal. The I-shaped hole effectively completes the punching of the connecting strip, resulting in two round ends in one punching operation. Similarly, a rectangular hole punching operation creates two right-angled ends in one punching operation. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Before lamination, the welding strips and connecting strips of photovoltaic cell strings need to be welded together to form a complete cell circuit. However, the connecting strips have different end structures from different module manufacturers. The mainstream end structures are right-angled ends and rounded ends. Since the connecting strips are rolled up and do not have different end structures, they are strip-shaped. Therefore, different end structures require the connecting strip sorting equipment to cut the connecting strips into different shapes.

[0023] However, current connector production equipment can only cut connectors into preset shapes. When the equipment needs to switch to producing different connectors, the entire machine needs to be shut down for maintenance, the original punching equipment needs to be removed, and a punching equipment of the required shape needs to be installed. Then, it needs to be debugged and tested for several days. This greatly reduces the production cycle and increases production costs.

[0024] like Figures 1 to 7 As shown, a photovoltaic module connector strip switching punching device includes a lateral moving device H, a front-rear moving device Q, and a punching unit 1. The punching unit 1 is installed at the movable end of the lateral moving device H, and the fixed end of the lateral moving device H is installed at the movable end of the front-rear moving device Q. The punching unit 1 includes at least two different punching heads 2. Two different end structures can be punched using the two different punching heads 2. When a change in end structure is required, the lateral moving device H is driven to move the punching unit 1, causing the other punching head 2 to work, thus achieving the punching of the new end structure without disassembling and adjusting the machine, thereby accelerating production efficiency. Simultaneously, by driving the front-rear moving device Q, the punching unit 1 can punch corresponding end structures at different positions on the connector strip, enhancing the overall structural compatibility and improving production efficiency.

[0025] In this embodiment, both the lateral movement device H and the forward and backward movement device Q are driven by a combination of cylinders and slide rails.

[0026] like Figure 3 As shown, the blanking unit 1 includes a blanking power unit 3, a blanking seat 4, and at least two different blanking heads 2 disposed in the blanking seat 4. The movable end of the blanking power unit is fixedly connected to the blanking head 2, and the blanking power unit drives the blanking head 2 to move within the blanking seat 4.

[0027] To facilitate the punching action of the punching head 2, a through hole is provided in the punching seat 4 at the position opposite to the punching head 2 in this embodiment.

[0028] To ensure the connecting strip passes precisely through the punching position, a connecting strip passage groove 5 is provided at the bottom of the punching seat 4, with a through hole vertically penetrating through the connecting strip passage groove 5. The connecting strip passage groove 5 ensures that the horizontal position of the connecting strip is limited within it before punching, guaranteeing the punching effect.

[0029] like Figure 6 As shown, an elastic element 6 is provided between the blanking seat 4 and the blanking power device 3. The elastic element 6 includes a guide post 61 and a rectangular spring 62. The guide post 61 is connected to the blanking power device 3 and passes through the blanking seat 4. The rectangular spring 62 is sleeved on the guide post 61 and abuts against the blanking power device 3 and the blanking seat 4.

[0030] With the elastic element 6, the connecting strip can be pressed by the punching seat 4 before punching. After punching, the punching head 2 leaves the connecting strip first, and then the punching seat 4 still presses the connecting strip under the elastic action. The connecting strip is released only when the punching power device 3 continues to rise, which improves the stability of the punching process and further ensures that the punching is complete and the material is accurately cut.

[0031] The punching head 2 includes a rounded-edge punching head 21 and a straight-edge punching head 22. The punching seat 4 has an I-shaped hole 7 opposite to the rounded-edge punching head 21 and a rectangular hole 8 opposite to the straight-edge punching head 22. Through the I-shaped hole 7, the punching of the connecting strip is completed so that both ends are rounded, forming two rounded ends in one punching operation. Similarly, the rectangular hole 8 forms two right-angled ends in one punching operation. The rectangular hole 8 and the I-shaped hole 7 are arranged along the moving direction of the transverse moving device H.
