SUMMARY

[0006] The rotating U-punching mechanism is used to bend and punch U on the workpiece one conveyed by the conveying mechanism.

[0007] The feeding mechanism comprises a second displacement mechanism and a second clamping mechanism at the moving end thereof, and the second displacement mechanism drives the second clamping mechanism to clamp the required workpiece two onto the bent workpiece one conveyed by the conveying mechanism.

[0008] After the feeding mechanism completes the predetermined action, the first clamping mechanism clamps the workpiece one, the third displacement mechanism moves the opening and closing mechanism to the predetermined position of the workpiece one, and the opening and closing mechanism drives the push block to push part of the workpiece one to complete the predetermined combination with the workpiece two.

[0010] Specifically, the wire on the terminal box is clamped by the first clamping mechanism, the terminal box and the wire are moved to the working range of the rotating U-shaped mechanism by moving the first clamping mechanism by the displacement mechanism, the wire is bent into a U shape by the rotating U-shaped mechanism, then the terminal box and the wire after being bent into a U shape are moved to the feeding mechanism, the buckle is placed on the part of the wire that has been bent into a U shape by the feeding mechanism, then the wire is clamped into the buckle on both sides of the U-shaped part by the wire supporting mechanism, and the workpiece one is combined with the workpiece two.

[0011] Further, the rotating U-shaped mechanism comprises a first displacement mechanism, a driving mechanism, a push plate, and a fixing mechanism. The driving mechanism is arranged at the moving end of the first displacement mechanism, and the push plate is arranged at the output end of the driving mechanism. The fixing mechanism is arranged on one side of the first displacement mechanism. The fixing mechanism comprises a fourth displacement mechanism and a pressing plate at the moving end of the fourth displacement mechanism. The fourth displacement mechanism drives the pressing plate to press the workpiece one carried by the carrying mechanism. The relative position between the push plate and the workpiece one is adjusted by the first displacement mechanism.

DETAILED DESCRIPTION

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] like Figures 1-9 As shown, the junction box clamping machine in this example includes a base 1 and various functional mechanisms, such as a preset mechanism 3, a conveying mechanism 2, a rotary U-shaped mechanism 4, a feeding mechanism 5, and a unloading mechanism 6. The preset mechanism 3, the conveying mechanism 2, the rotary U-shaped mechanism 4, the feeding mechanism 5, and the unloading mechanism 6 are installed on the base 1. The preset mechanism 3, the rotary U-shaped mechanism 4, the feeding mechanism 5, and the unloading mechanism 6 are arranged sequentially along the feeding path of the conveying mechanism 2.

[0044] The base 1 includes a frame-type main body and brackets installed on the top surface that interface with the corresponding functional mechanisms, supporting the corresponding functional mechanisms. Circuit boards and other mechanisms connected to each functional mechanism are installed inside the cavity of the base 1. A display panel control mechanism can also be added, which interfaces with the aforementioned functional mechanisms. The actions of each functional mechanism can be controlled by the program built into the display panel control mechanism.

[0045] like Figure 1 , Figure 2 , Figure 3 As shown, the pre-positioning mechanism 3 is installed near the head end of the transport mechanism 2. The pre-positioning mechanism 3 includes a telescopic lifting mechanism 31 and a material seat 32 at its moving end. The telescopic lifting mechanism 31 lifts the material seat 32 longitudinally. The top surface of the material seat 32 is formed with a material groove 33 for placing one end of the workpiece. In this example, the workpiece is a junction box 11, and the material groove 33 can hold the box body of the junction box 11. The transport mechanism 2 transports the workpiece 1 from the pre-positioning mechanism 3 to the working range of the rotary U-shaped mechanism 4, the feeding mechanism 5, and the unloading mechanism 6.

[0046] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in this example, the rotary U-shaped mechanism 4 includes a first shifting mechanism, a drive mechanism 44, a push plate 43, and a fixing mechanism 45. The drive mechanism 44 is installed longitudinally at the moving end of the first shifting mechanism, and the output end of the drive mechanism 44 faces downward. The drive mechanism is like a drive motor, and the push plate 43 is installed at the output end of the drive motor. The first shifting mechanism adjusts the relative position of the push plate 43 and the workpiece. When the push plate is in a predetermined position, the drive mechanism 44 rotates the push plate 43, and the push plate bends the workpiece simultaneously, such as bending the wire connected to the junction box into a U-shape.

[0047] For the first displacement mechanism, if the first displacement mechanism comprises a linear reciprocating displacement mechanism 41 and a telescopic lifting mechanism 42 at the moving end of the linear reciprocating displacement mechanism 41, the linear reciprocating displacement mechanism 41 is of a screw displacement type, and the telescopic lifting mechanism 42 is of a lifting cylinder, the linear reciprocating displacement mechanism 41 is horizontally arranged on the corresponding support in the base 1, and the moving end of the telescopic lifting mechanism 42 is fixed with a driving mechanism 44 in the longitudinal direction. The first displacement mechanism adjusts the longitudinal height and horizontal position of the push plate, and other displacement mechanisms can also be selected as long as the horizontal and longitudinal positions can be adjusted.

[0048] A fixing mechanism 45 is arranged at the base 1 on the side of the first displacement mechanism, and the fixing mechanism 45 comprises a fourth displacement mechanism 451 and a horizontally arranged pressing plate 452 at the moving end of the fourth displacement mechanism 451. The fourth displacement mechanism 451 drives the pressing plate 452 to press the workpiece carried by the carrying mechanism 2. The fourth displacement mechanism 451 has a longitudinal lifting function, i.e., the position of the pressing plate 452 is adjusted in the longitudinal direction, and the lifting cylinder is commonly used. The lifting cylinder is fixed on the corresponding support in the base. When the box body of the junction box carried by the carrying mechanism 2 is below the pressing plate 452 (i.e., within the working range of the rotating U-bending mechanism), the fourth displacement mechanism 451 lowers the pressing plate 452 to press and fix the box body, so that the subsequent U-bending operation is conveniently and stably performed. Of course, other displacement mechanisms, such as two-way and three-way displacement mechanisms, can also be used as the fourth displacement mechanism.

[0049] For the push plate, the push plate 43 comprises a connecting plate 431 and a protruding column 432. The connecting plate 431 is of a flat plate type, the connecting plate 431 is horizontally arranged, and the output end of the driving mechanism 44 is fixed at one end of the connecting plate 431. The protruding column 432 is arranged at the bottom surface of the other end of the connecting plate 431 in the longitudinal direction, and the protruding column 432 is arranged non-concentrically with the rotating center of the driving mechanism 44. As shown in Figure 1 、 Figure 2 、 Figure 4 When the carrying mechanism 2 moves the junction box to the rotating U-bending mechanism 4, the box body of the junction box 11 is within the working range of the fixing mechanism 45, and the pressing plate presses and fixes the box body. At the same time, the wire in the junction box is within the working range of the push plate, the horizontal position of the push plate 43 is adjusted by the linear reciprocating displacement mechanism 41, the longitudinal position of the push plate 43 is adjusted by the telescopic lifting mechanism 42, the protruding column 432 in the push plate 43 is arranged at one side of the wire, the driving mechanism 44 drives the horizontal rotation of the connecting plate 431, the protruding column 432 is synchronously moved and pushes the wire to be bent into a U shape. Preferably, a groove is formed on the peripheral wall of the protruding column 432, the groove abuts against the wire, and the stability during the bending process is improved. In addition, after the wire is bent into a U shape, the push plate 43 can be reset by the linear reciprocating displacement mechanism 41, and the end of the bent wire is in a straight line under the pushing of the protruding column, which facilitates the subsequent clamping of the carrying mechanism.

[0050] As shown in Figure 1 ,Figure 2 、 Figure 7 As shown in FIG. 5, the feeding mechanism 5 in this example includes a second displacement mechanism and a second clamping mechanism 53 at the moving end of the second displacement mechanism, and the second clamping mechanism 53 clamps the required workpiece two on the bent workpiece one conveyed by the conveying mechanism under the driving of the second displacement mechanism.

[0051] The second displacement mechanism includes a linear reciprocating displacement mechanism two 51 and a telescopic lifting mechanism two 52 at the moving end of the linear reciprocating displacement mechanism two 51, and the moving end of the telescopic lifting mechanism two 52 is longitudinally arranged with the second clamping mechanism 53. The linear reciprocating displacement mechanism two 51 is commonly a screw displacement type and is horizontally arranged on the corresponding support in the base. The second clamping mechanism is commonly a jaw cylinder, which clamps the workpiece two, which is commonly a buckle 12 as shown in FIG. 6, which is an overall elliptical ring body and has an inlet formed at the bottom surface for the wire to enter, and the two ends of the cavity of the buckle 12 form a buckle opening for clamping the wire. Figure 7

[0052] In use, when the conveying mechanism 2 conveys the U-shaped junction box to the working range of the feeding mechanism 5, the second clamping mechanism 53 is moved above the U-shaped wire part by the linear reciprocating displacement mechanism two 51, the position of the second clamping mechanism 53 is adjusted by the telescopic lifting mechanism two 52, the second clamping mechanism 53 releases the buckle 12, and the buckle falls on the U-shaped wire part. The part of the wire enters the cavity from the inlet at the bottom surface of the buckle. In this state, the wire is not completely combined with the buckle, that is, the wire in the cavity is not clamped by the buckle opening.

[0053] As shown in FIG. 7, the vibration feeding mechanism 7 is arranged at one side of the second displacement mechanism, that is, at the tail end of the linear reciprocating displacement mechanism two 51. The vibration feeding mechanism 7 is commonly a vibration feeding disc, which can be directly purchased from the market. The vibration feeding mechanism 7 is used to convey the workpiece two. Figure 1 、 Figure 2 、 Figure 6

[0054] The discharge port of the vibration feeding mechanism 7 is provided with a distribution mechanism 10, which includes a telescopic mechanism one 101 and a material seat one 102 at the moving end of the telescopic mechanism one 101. The material seat one 102 is moved horizontally and reciprocally by the telescopic mechanism one 101. In the normal state, the material seat one 102 is at the discharge port, and the end surface of the material seat one 102 towards the discharge port is formed with a material groove one 103 for arranging the workpiece two. The material groove one 103 includes a groove cavity for arranging the buckle and a notch formed at the groove wall. The notch extends along the end surface of the material seat one to the opposite surface, so that the jaw extends into the groove cavity for clamping. For the telescopic mechanism one, it is commonly a telescopic cylinder, which is arranged on the corresponding support in the base.

[0055] ​​In use, when the buckles at the discharge port of the vibration feeding mechanism are in a side-by-side state, the first buckle is conveyed to the first trough, then the first seat is moved by the first telescopic mechanism, so that the first trough is within the working range of the second clamping mechanism, the second clamping mechanism is adjusted by the second linear reciprocating displacement mechanism cooperating with the second telescopic lifting mechanism, and then the buckle is conveyed to the U-shaped wire, the first seat is reset to the discharge port, and the next buckle enters the first trough, thereby facilitating stable feeding.

[0056] As shown in Figure 1 , Figure 2 , Figure 10 , in this example, the unloading mechanism 6 includes a fifth displacement mechanism and a third clamping mechanism 63, and the third clamping mechanism 63 is installed at the moving end of the fifth displacement mechanism. The fifth displacement mechanism includes a third linear reciprocating displacement mechanism 61 and a fourth telescopic lifting mechanism 62. The third linear reciprocating displacement mechanism 61 is commonly a screw displacement type and is horizontally arranged in the corresponding support in the base 1. The fourth telescopic lifting mechanism 62 is installed at the moving end of the third linear reciprocating displacement mechanism 61 in the longitudinal direction. The third clamping mechanism 63 is installed at the moving end of the fourth telescopic lifting mechanism 62. The fourth telescopic lifting mechanism is commonly a lifting cylinder, and the third clamping mechanism is commonly a cylinder clamp jaw.

[0057] When the carrier mechanism conveys the combined workpiece 1 and workpiece 2 to the working range of the unloading mechanism 6, the position of the third clamping mechanism 63 is adjusted by the third linear reciprocating displacement mechanism 61 cooperating with the fourth telescopic lifting mechanism 62, such as to the position where the third clamping mechanism can clamp the wire. The third clamping mechanism clamps a single portion of the wire, or the third clamping mechanism clamps the U-shaped portion of the wire by expanding the support outside the separated clamping jaws, and then it is conveyed to the next work station or storage tank. The third linear reciprocating displacement mechanism extends in the feeding direction of the carrier mechanism.

[0058] For the carrier mechanism, as shown in Figure 1 , Figure 2 , Figure 8 , Figure 9 , in this example, the carrier mechanism 2 includes a first displacement mechanism 21, a first clamping mechanism 22, and a wire supporting mechanism. The first displacement mechanism is a screw displacement type, and other types of displacement mechanisms can also be used, such as a belt sliding table module.

[0059] The moving end of the first displacement mechanism 21 is fixedly installed with a mounting seat 24. The mounting seat 24 extends in the displacement direction of the first displacement mechanism 21, and the first clamping mechanism 22 is installed on the mounting seat 24 in the conveying direction of the first displacement mechanism 21. The first clamping mechanism is commonly a cylinder clamp jaw type.

[0060] In this example, the base 1 is provided with a preset mechanism 3, a rotary U-shaped mechanism 4, a feeding mechanism 5, an unloading mechanism 6, etc., i.e., there are four work stations. The first clamping mechanism 22 is installed at the front end, the tail end and the middle position of the mounting seat 24 to convey the material in a reciprocating manner.

[0061] In order to conveniently hold the wire in the junction box at the preset mechanism, the telescopic mechanism 23 is installed at the front end of the mounting seat 24 to horizontally reciprocate, such as telescoping along the feeding direction of the displacement mechanism 1, and the first clamping mechanism 22 is installed at the moving end of the telescopic mechanism 2, so as to conveniently adjust the position of the clamping jaw of the first clamping mechanism, thereby better holding the wire.

[0062] In order to conveniently form the U-shaped structure, two first clamping mechanisms 22 are oppositely installed at the middle position of the mounting seat 24, so as to respectively hold the wires on both sides of the cavity.

[0063] At the tail end of the mounting seat 24, the wire supporting mechanism is oppositely arranged with the first clamping mechanism 22, and after moving to a predetermined position, the wire supporting mechanism is actuated to respectively push the wires on both sides of the U-shaped cavity into the clamping opening of the buckle 12 to be fixed, thereby completing the combination of the wire in the junction box and the buckle, and facilitating the subsequent blanking of the blanking mechanism. As for the wire supporting mechanism, such as the third displacement mechanism 25 and the opening and closing mechanism 26 at the moving end thereof, the third displacement mechanism 25 is such as a telescopic lifting type, commonly such as a lifting cylinder, and the third displacement mechanism 25 is fixed on the mounting seat 24 in the longitudinal direction to lift the opening and closing mechanism 26 in the longitudinal direction, and of course, two-way or three-way displacement mechanisms can also be selected to meet the adjustment of the longitudinal position. The opening and closing mechanism 26 is commonly a clamping cylinder, and the push block 27 is fixed at the moving end of the cylinder. The push block has various structures, and only has a longitudinal part, which can push the corresponding wire part into the clamping opening of the buckle when moving to the side. Preferably, the push block 27 has a structure as shown in the figure, which is symmetrical with two push blocks, and the upper part of the combined push block is in a cross shape, the upper part of a single push block is in an L shape, the transverse end of the push block 27 can move upward to adjust the position of the wire, and the longitudinal end of the push block can push the corresponding wire part into the clamping opening of the buckle, thereby improving the stability of operation. Figure 8

[0064] Specifically, during use, the first clamping mechanism 22 at the front end is moved between the preset mechanism 3 and the rotary U-shaped mechanism 4 through the reciprocating movement of the displacement mechanism 1, so as to clamp the wire in the junction box at the preset mechanism, and then transported to the working range of the rotary U-shaped mechanism, so that the rotary U-shaped mechanism can perform U-bending on the wire in the junction box.

[0065] The first clamping mechanism 22 at the middle is moved between the rotary U-shaped mechanism 4 and the feeding mechanism 5, so that the two first clamping mechanisms can clamp the wire in the junction box which has been U-bent, and then moved from the rotary U-shaped mechanism to the working range of the feeding mechanism, so that the feeding mechanism can place the buckle on the U-bent part of the wire.

[0066] ​The first clamping mechanism 22 at the end is moved between the feeding mechanism 5 and the discharging mechanism 6, so that the first clamping mechanism moves the junction box with the buckle to the working range of the discharging mechanism from the feeding mechanism, then the opening and closing mechanism is moved up on the third displacement mechanism in the wire supporting mechanism, the push block is in the U-shaped cavity of the wire, the opening and closing mechanism is separated, and the two push blocks are moved to the side to push the corresponding wire part into the buckle to complete the combination. Then the fifth displacement mechanism in the discharging mechanism adjusts the position of the third clamping mechanism, so that the third clamping mechanism clamps the wire of the junction box, and then the fifth displacement mechanism moves the third clamping mechanism to the required position.

[0067] In addition, in order to improve the operation stability, the sliding seat one 8 and the sliding seat two 9 can be added, as shown in Figure 1 、 Figure 2 The sliding seat one 8 and the sliding seat two 9 are fixed side by side on the base 1, the sliding seat one 8 and the sliding seat two 9 extend along the feeding path of the conveying mechanism 2, and the moving path of the first clamping mechanism 22 is between the sliding seat one 8 and the sliding seat two 9. According to the requirement, the height of the sliding seat one and the sliding seat two is adjusted to be flat with the clamping jaw end, or slightly higher or lower than the clamping jaw end. When the wire of the junction box is clamped and moved by the conveying mechanism, the box body of the junction box is supported by the sliding seat two, and the box body moves along the sliding seat two. When moving to the lower side of the pressing plate, the pressing plate is lowered to fix the box body, and the wire of the junction box is supported by the sliding seat one and moves along the sliding seat one.

[0068] Of course, according to the requirement, the preset mechanism, the vibration feeding mechanism and the discharging mechanism can be removed, and manual replacement and the like can be used.

[0069] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution belonging to the idea of the present application is within the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
