Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] Referring to Figure 2 、 Figure 3 And Figure 4 An embodiment provided by the utility model: a kind of automatic wire binding equipment of photovoltaic junction box, including base 1, the top of base 1 is fixedly connected with motor one 3, the output of motor one 3 is fixedly connected with rotating shaft 4, the top of rotating shaft 4 is fixedly connected with turntable 5, the top of turntable 5 is provided with cylinder 6, the output of cylinder 6 is fixedly connected with sliding block 7, the outer wall of sliding block 7 is hinged with multiple connecting rods 8, the top of turntable 5 is slidably connected with multiple winding frames 9, the top of base 1 is rotatably connected with rotating rod 11, the top of rotating rod 11 is fixedly connected with lead screw one 13, the outer wall of lead screw one 13 is threadedly connected with multiple wire clamping blocks 15, the top of turntable 5 is provided with auxiliary ribbon assembly.

[0026] Specifically, the base 1 provides support for the upper components, the motor 3 drives the rotating winding and cable lifting and laying flat, the cylinder 6 drives the slider 7 and connecting rod 8 to slide, and then the hinge drives the winding frame 9 to retract and expand to provide support for the winding of the cable, and the clamping block 15 clamps the cable in the junction box to keep it stable during the winding and binding process and prevent tangling.

[0027] Reference Figure 2 and Figure 5 The auxiliary cable tie assembly includes a second motor 17, which is fixedly connected to the top of the turntable 5. The output end of the second motor 17 is fixedly connected to a second lead screw 19. The outer wall of the second lead screw 19 is threadedly connected to a lifting plate 20. The top of the turntable 5 is fixedly connected to a support plate 18. The top of the second lead screw 19 is rotatably connected to the inner wall of the support plate 18. The lifting plate 20 is slidably connected to the outer wall of the support plate 18.

[0028] Specifically, after the cable is coiled, the starting motor 17 drives the lead screw 19 to rotate, and the lifting plate 20 moves up and down along the lead screw 19 through the threaded connection, thereby lifting the cable wound on the lower winding frame 9 to the middle section of the winding frame 9, where it is combined with the cable wound on the upper winding frame 9, making it convenient to use the cable tie machine 23 for cable tie installation. The support plate 18 limits the sliding of the lifting plate 20 to prevent rotation during the lifting process.

[0029] Reference Figure 1 and Figure 2 A support frame 2 is fixedly connected to the top of the base 1. A fixing plate 16 is fixedly connected to the outer wall of the support frame 2. Multiple mechanical claws 21 are slidably connected to the outer wall of the support frame 2. Multiple baffles 22 are fixedly connected to the top of the base 1. A cable tie machine 23 is provided on the outer wall of the baffle 22. A discharge plate 24 is fixedly connected to the opposite side of the outer wall of the two baffles 22.

[0030] Specifically, the support frame 2 provides protection and support for the operation of the internal components, the fixing plate 16 fixes the junction box during the winding and bundling process, the mechanical claw 21 grabs the junction box and cable and moves it to the discharge plate 24 for automatic unloading, and the cable tie machine 23 ties and installs the coiled cable. This is existing technology and will not be described in detail.

[0031] Reference Figure 3 and Figure 5 The bottom end of the slider 7 is slidably connected to the top end of the turntable 5, one end of the connecting rod 8 is hinged to the bottom end of the winding frame 9, the top end of the turntable 5 is provided with a slide rail, and multiple limit blocks 10 are fixedly connected to the top end of the turntable 5. The winding frame 9 is slidably connected inside the slide rail and slidably connected to the inner wall of the limit block 10.

[0032] Specifically, the cylinder 6 drives the slider 7 to slide back and forth, and the hinge drives the connecting rod 8, which in turn drives the winding frame 9 to retract and slide towards the center, so that the winding frame 9 is freed from the support of the cable, making it convenient for the mechanical claw 21 to grab the cable and lift it for unloading. The slide rail and the limit block 10 ensure that the winding frame 9 can always keep a straight line when sliding.

[0033] Reference Figure 2 Both the outer walls of the rotating shaft 4 and the rotating rod 11 are fixedly connected to the synchronous pulley 12, and the outer wall of the synchronous pulley 12 is fitted with a synchronous belt.

[0034] Specifically, the synchronous pulley 12 and synchronous belt transmit power, so that the power of motor 3 can simultaneously drive the rotating shaft 4 and the rotating rod 11 to rotate, thereby enabling the winding assembly and the cable laying assembly to operate and stop simultaneously and work together. While winding the cable, the cable is evenly distributed on the winding frame 9, which is convenient for installing cable ties.

[0035] Reference Figure 4 The lead screw 13 is a reciprocating lead screw. The outer wall of the lead screw 13 is symmetrically provided with threads at both ends. The lead screw 13 is rotatably connected to and passes through the inner wall of the support frame 2. The outer wall of the support frame 2 is fixedly connected to a limit rod 14 on the opposite side. The clamping block 15 is slidably connected to the outer wall of the limit rod 14.

[0036] Specifically, the lead screw 13 is symmetrically provided with threads at both ends, both of which are reciprocating threads, so that the two clamping blocks 15 connected to the threads on the outer wall of the lead screw 13 can slide back and forth, and the two sliding directions are always opposite, thereby driving the two cables of the junction box to wind into a coil in opposite directions, and the sliding of the clamping blocks 15 is limited by the limiting rod 14 to prevent rotation during the sliding process.

[0037] Reference Figure 6 The outer wall of the baffle 22 is fixedly connected to the base plate 25, and the bottom end of the turntable 5 is slidably connected to the top end of the base plate 25.

[0038] Specifically, the baffle 22 provides protection for the internal components and supports the base plate 25, which in turn supports the rotation of the turntable 5 and prevents it from tilting during rotation.

[0039] Working principle: When using this photovoltaic junction box automatic cable tying device, first place the junction box on the fixing plate 16 and fix it with the upper and lower side buckles. Wrap the cables at the upper and lower ends on the upper and lower multiple winding frames 9 respectively through the wire clamping blocks 15. Start the motor 3 to drive the rotating shaft 4 and the turntable 5 to rotate. The multiple winding frames 9 installed on the turntable 5 will rotate synchronously with the turntable 5, so that the cable is wrapped around the winding frame 9. At the same time, the rotation of the rotating shaft 4 is transmitted to the rotating rod 11 through the synchronous wheel 12, thereby driving the lead screw 13 to rotate. Since the lead screw 13 is equipped with a two-stage reciprocating thread, the two wire clamping blocks 15 connected to the outer wall thread will slide repeatedly along the lead screw 13 in the vertical direction, driving the cable to move up and down synchronously. This allows the cable to be wrapped into a coil around the winding frame 9 while being laid flat in the vertical direction, preventing the coil width from being too large and facilitating the binding of cable ties later.

[0040] After the cable is wound, start motor 217 to drive screw 219 to rotate, which in turn drives lifting plate 20, which is threaded on the outer wall of screw 219, to rise vertically along the direction of screw 219. This will lift the cable wound on the lower winding frame 9 and make it converge with the upper cable in the middle of the winding frame 9. At this time, start the cable tie machine 23 installed on the support plate 18 to tie both ends of the cable simultaneously.

[0041] After the cable ties are completed, the mechanical claw 21 is activated to clamp the junction box and the cable. Then, the cylinder 6 is activated to drive the slider 7 and the connecting rod 8 to slide. Through the hinge, the two winding frames 9 on both sides slide towards the center, reducing the distance between the winding frames 9. After that, the mechanical claw 21 is activated again to lift and remove the cable, which falls from the discharge plate 24 to complete the cable tying.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
