Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic component production, and particularly relates to a junction box installation clamping mechanism. [Background technology]

[0002] When assembling the junction box on the photovoltaic module, it is necessary to first use the grasping mechanism to grasp the junction box, and then use the moving module to move the junction box to the top of the U-shaped busbar of the photovoltaic module, so that the two sockets of the junction box are respectively aligned with the two vertical parts of the U-shaped busbar; then move the junction box downward so that the two vertical parts of the U-shaped busbar are respectively inserted into the two sockets; then the two vertical parts are respectively bent to both sides to connect with the junction box.

[0003] The prior art patent publication number CN219445128U discloses a grabbing mechanism and assembly device for a junction box. The box body clamping module for clamping the junction box and the external pull-out module for realizing the bending of the busbar leads are arranged on the mobile module and are located at two different positions. First, the box body clamping module clamps the junction box to the installation position, then releases the junction box and moves to make way, and the external pull-out module moves into the junction box to pull outward and bend the two busbar leads in the junction box. After the box body clamping module clamps the junction box to the installation position, it releases its clamping. The junction box may not be well glued with glue, and there is a risk of displacement; in addition, the box body clamping module moves to make way, and the mobile module drives the external pull-out module to move into the junction box, which has a secondary movement, reducing the assembly efficiency of the junction box.

[0004] Therefore, it is necessary to provide a new junction box installation clamping claw mechanism to solve the above technical problems. [Contents of the utility model]

[0005] The main purpose of the utility model is to provide a junction box installation clamping mechanism, which can greatly improve the installation accuracy and installation quality of the junction box and also improve installation efficiency.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a junction box installation clamping mechanism, which includes a mounting plate, a pressure plate elastically floatingly arranged below the mounting plate and used to press the surface of the junction box, a first cylinder fixed to the upper surface of the mounting plate, a pair of clamping claws driven by the first cylinder to move left and right, a second cylinder fixed to the lower surface of the mounting plate, and a pair of lead wire pushing claws driven by the second cylinder to pass through the pressure plate to move forward and backward.

[0007] Furthermore, the pressing plate is hung on the mounting plate through four hanging rods, and the hanging rods are sleeved with springs for pressing the pressing plate downward.

[0008] Furthermore, the pressing plate is provided with an avoidance notch corresponding to the position of the internal cavity of the junction box.

[0009] Furthermore, the clamping claw extends downward and extends out of the lower surface of the pressing plate.

[0010] Furthermore, the mounting plate is provided with slide rails distributed front and back, and the second cylinder body is slidably arranged on the slide rails through a slider, and is locked and fixed with screws after the position is adjusted.

[0011] Furthermore, the mounting plate is provided with adjusting screws on both sides of the front and rear of the second cylinder, and the front and rear position of the second cylinder is adjusted by the adjusting screws.

[0012] Compared with the prior art, the utility model has the beneficial effects of a junction box installation clamping mechanism: an elastic floating pressure plate is arranged on the clamping mechanism, which always presses and holds the junction box during the junction box assembly process, greatly improving the bonding strength between the junction box and the photovoltaic module; during the lead bending operation, the junction box remains under pressure, and the relative position of the lead bending claw and the junction box claw is exactly consistent with the relative position of the junction box and the lead after assembly, so that there is no need to loosen the clamping of the junction box when the lead is bent, effectively solving the risk of junction box displacement, and the lead bending operation can be performed immediately after the junction box is installed, thereby improving the assembly efficiency of the junction box.

[0018] Embodiment 1:

[0019] Please refer to Figure 1-Figure 2The present embodiment is a terminal box mounting clamp mechanism 100, which includes a mounting plate 1, a pressure plate 2 elastically floatingly arranged below the mounting plate 1 and used for pressing the surface of the terminal box, a first cylinder 3 fixed to the upper surface of the mounting plate 1, a pair of clamps 4 driven by the first cylinder 3 to move left and right, a second cylinder 5 fixed to the lower surface of the mounting plate 1, and a pair of lead claws 6 driven by the second cylinder 5 to pass through the pressure plate 2 to move forward and backward.

[0020] The pressing plate 2 is hung on the mounting plate 1 through four hanging rods 7, and the hanging rods 7 are sleeved with springs 8 for pressing the pressing plate 2 downward. The pressing plate 2 is provided with an escape notch 21, which corresponds to the position of the internal cavity of the junction box. The outer peripheral body range of the pressing plate 2 located at the escape notch 21 can cover the outline of the junction box body, so as to firmly hold the junction box, while exposing the internal cavity of the junction box, so that the lead wire claw 6 can pass through the escape notch 21 and extend into the internal cavity of the junction box to bend the lead wire.

[0021] The clamping jaws 4 extend downwardly out of the lower surface of the pressing plate 2 so that after the pressing plate 2 presses the upper surface of the junction box, the clamping jaws 4 can reliably clamp the junction box.

[0022] In order to improve the accuracy of the lead wire bending by the lead wire pusher 6, the front and rear position of the second cylinder 5 is adjustable on the mounting plate 1. Specifically, the mounting plate 1 is provided with slide rails 9 distributed front and back, and the second cylinder 5 body is slidably set on the slide rails 9 through a slider 10. Adjustment screws 11 are provided on the mounting plate 1 at the front and rear sides of the second cylinder 5. The front and rear position of the second cylinder 5 can be adjusted by the two front and rear adjustment screws 11, thereby realizing the position adjustment of the lead wire pusher 6.

[0023] When a junction box installation clamping mechanism 100 of the present embodiment is working, the pressing plate 2 is first used to press and hold the surface of the junction box, and then the first cylinder 3 drives the clamping claw 4 to clamp the junction box, and then the junction box is moved to the junction box installation position. When assembling the junction box, the pressing plate 2 continues to press the junction box on the photovoltaic module, so that the lower surface of the junction box and the glue on the photovoltaic module are firmly adhered together. At this time, the lead wire claw 6 is located between the two leads, and the second cylinder 5 drives the lead wire claw 6 to open each other and bend the leads outward. During this process, the junction box is always pressed and fixed by the pressing plate 2, which greatly improves the assembly accuracy of the junction box. At the same time, when the leads are bent, the clamping claw mechanism as a whole does not need to be horizontally transferred, thereby improving the assembly efficiency of the junction box.

[0024] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
