Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic junction box processing equipment, and in particular to a photovoltaic junction box cable clip device. Background Art

[0002] The photovoltaic junction box is a crucial component in a solar photovoltaic system, located between the solar cell array and the solar charging controller, providing connectivity and power transmission. It primarily consists of a box, cables, and connectors. The required length of the cables connecting the solar cell array and the solar charging controller often varies. To ensure sufficient cable length, the junction box cable must be long. However, excessively long cables are inconvenient to package and transport. Therefore, during shipping, the junction box cable is typically bent and secured, reducing the overall size and facilitating transport. Furthermore, the long cable makes it more susceptible to loosening or falling off during use due to external factors (such as wind and vibration). Therefore, after the junction box is assembled on the photovoltaic panel, any remaining cable must be quickly and easily reattached. Therefore, manufacturers currently use a snap-fit ​​mechanism with tabs at both ends to bend and secure the junction box cable after the box is completed.

[0003] When using clips to clamp the cables of a photovoltaic junction box, it is necessary to determine the bending position of the cable to be bent. Traditional bending methods are all done manually, which is not only costly, but also difficult to accurately control the bending length when manually bending the clip cables.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0032] like Figures 1 to 7As shown, a photovoltaic junction box cable clamping device includes a shell 7 with a main control device 8, a fixing seat 5 arranged in the shell 7, a first material picking mechanism 2 and a second material picking mechanism 3 arranged in the fixing seat 5, and a folding line module 1 arranged on one side of the fixing seat 5 and with a cable 62; the folding line module 1 includes a mounting block 11, a placement table 6 arranged on the rear side of the mounting block 11, a lifting cylinder 111 and a rotary servo 112 arranged at the bottom end of the mounting block 11, and a distance adjustment module 113 at one end of the lifting cylinder 111; wherein, the mounting block 11 is equipped with a central axis 12 that rotates vertically along the axis, and the side of the mounting block 11 is equipped with a bending axis 13 with an axis vertically and rotating about the same height as the central axis 12; the placement table 6 is provided with a wire box 61 for placing the cable 62 and a shell pressure plate 63 for fixing the wire box 61, and the first material picking mechanism 2 is provided with a tail portion for clamping the cable 62 The tail clamp 14 and the wire drawing claw 20 that clamps one end of the cable 62 are installed, and the cable 62 is tightened above the gap between the center axis 12 and the bending axis 13 through the tail clamp 14 and the wire drawing claw 20; the mounting block 11 and the placement table 6 are both installed on the same side of the distance adjustment module 113, and the distance adjustment module 113 is used to adjust the distance between the mounting block 11 and the placement table 6, thereby adjusting the bending position of the cable 62; when the lifting cylinder 111 drives the mounting block 11 to move upward, the cable 62 enters the gap between the center axis 12 and the bending axis 13. According to the bending position requirements of the product, the user changes the distance between the mounting block 11 and the placement table 6, opens the wire drawing claw 20 and the tail clamp 14, and the mounting block 11 is driven to rotate along the vertical axis of the center axis 12 through the lower rotation servo 112, drives the bending axis 13 to rotate along the center axis 12, and bends the cable 62 backward.

[0033] It needs to be further explained that, Figure 7 As shown, the main control device 8 in this embodiment is the main control screen. After the embodiment is powered on, the user can set the operating mode of the first material picking mechanism 2, the second material picking mechanism 3, the transfer module 51 and the folding line module 1 through the main control device 8.

[0034] It is worth noting that the fixed seat 5 is provided with a transfer module 51, which can simultaneously control the first material picking mechanism 2 and the second material picking mechanism 3 to move in the same direction; the bottom end of the second material picking mechanism 3 is provided with a wire clamping group 31, and the bottom end of the wire clamping group 31 is provided with a wire clamping claw 32 for clamping the bent cable 62, and one end of the wire clamping claw 32 is provided with two wire clamping plates 34 with a clamping groove 33;

[0035] When the bending is completed, the first material picking mechanism 2 opens the tail clamp 14, so that the first material picking mechanism 2 is separated from the cable 62, and then the first material picking mechanism 2 moves horizontally through the transfer module 51, and the fixed seat 5 automatically moves the second material picking mechanism 3 to the top of the bent cable 62, and the wire clamping group 31 drives the wire clamping claw 32 to move, so that the wire clamping claw 32 moves to the two sides of the cable 62 after bending, and the wire clamping plate 34 clamps the cables 62 on both sides after bending and clamps the cable 62 into the groove 33, so that the cable 62 remains in the bent state. Finally, the lifting cylinder 111 drives the mounting block 11 to reset downward, and at the same time, the shell pressure block 63 is lifted by the lifting cylinder 52, so that the cable 62 is clamped in the wire clamping claw 34 and remains in the bent state.

[0036] This photovoltaic junction box cable clip device can be used alone or in conjunction with other modules on the production line. The drawings of this embodiment are for use in the production line. When the device is working, the cable 62 to be clipped is tightened through the tail clamp 14 and the wire-drawing clamp 20, so that the part of the cable to be bent corresponds to the position above the gap between the central axis 12 and the bending axis 13, and then the central axis 12 and the bending axis 13 are driven upward by the lifting cylinder 111, so that the cable 62 is located in the middle of the central axis 12 and the bending axis 13; at this time, the mounting block 11 is driven to rotate along the axis of the central axis 12 together with the central axis 12 and the bending axis 13 through the rotating servo 112, so that the cable 62 is bent. During the bending process, the housing pressure plate 63 and the tail clamp 14 position the junction box body and the cable portion, ensuring accurate bending. The bending shaft 13 adheres to the cable 62 during rotation, allowing the cable 62 to be bent along the central axis 12. This bending process controls the curvature, not only making the bending position more accurate, but also ensuring that the internal wiring and electrical connection metal of the cable are not damaged during bending, ensuring the circuit connection after the bending. The bending operation is completed entirely automatically, requiring no manual operation, greatly saving labor and reducing production costs.

[0037] One end of the wire clamping jaw 32 is further provided with an abutment plate 35, which is arranged between two wire clamping plates 34. The wire clamping plates 34 clamp the cable 62 so that one end of the cable is fixed between the abutment plate 35 and any one of the wire clamping plates 34 to maintain the curvature of the cable 62.

[0038] The fixing seat 5 is also provided with a lifting cylinder 52, and a clamping block 53 is provided at one end of the lifting cylinder 52. The lifting cylinder 52 is used to control the downward movement of the clamping block 53, and the shell pressure plate 63 is provided with a connecting plate 64 for clamping with the clamping block 53; during use, the lifting cylinder 52 controls the clamping block 53 to move downward so that the clamping block 53 clamps the connecting plate 64, and then the lifting cylinder 52 controls the clamping block 53 to reset, so that the clamping block 53 drives the shell pressure plate 63 to leave the wire box 61.

[0039] Working principle: The first material picking mechanism 2 moves horizontally through the transfer module 51 to place the wire box 61 on the placement table 6, and the cable 62 is clamped and tightened by the tail clamp 14 and the wire drawing claw 20. The part of the cable to be bent is correspondingly transferred to the gap above the central axis 12 and the bending axis 13 through the transfer module 51. At the same time, the lifting cylinder 52 presses down to drive the shell pressure plate 63 to press the wire box 61, and the lifting cylinder 111 lifts the central axis 12 and the bending axis 13 so that the cable 62 is just Located between the central axis 12 and the bending axis 13; the tail clamp 14 and the wire drawing clamp 20 are opened, and the first material picking mechanism 2 is reset through the transfer module 51. Since the first material picking mechanism 2 and the second material picking mechanism 3 move synchronously through the transfer module 51, the second material picking mechanism 3 automatically moves to the top of the cable 62; then, the mounting block 11 is driven to rotate along the axis of the central axis 12 together with the central axis 12 and the bending axis 13 through the rotating servo 112, so that the cable 62 is bent. During the bending process, the junction box body and the cable part are positioned by the shell pressure plate 63, so that the bending position is accurate, and the bending shaft 13 is attached to the cable 62 during rotation, so that the cable 62 is bent along the central axis 12; the wire clamping group 31 opens the wire clamping claw 32, and the lifting cylinder 111 drives the central axis 12 and the wire bending shaft 13 to move downward, so that the two sides of the cable 62 after bending are located in the wire clamping claw 32, and the wire clamping plate 34 clamps the two sides of the cable 62 after bending and clamps the cable 62 into the clamping groove 33, so that the cable 62 remains in a bent state.
