Description

Technical Field

[0001] The invention relates to the technical field of assembly devices, and in particular to a wiring buckle machine for a junction box. Background Art

[0002] The junction box generally includes the box body and the wires at its ends. In the subsequent assembly process, some companies need to U-bend the wires, that is, bend them into a U shape and shape them. This part of the process is currently basically performed manually, with a low degree of automation and low efficiency, and needs to be improved. Summary of the invention

[0003] To solve at least one of the above technical defects, the present invention provides the following technical solutions:

[0004] This application document discloses a junction box wire buckling machine, including a carrying mechanism, a rotating U-punching mechanism, and a feeding mechanism, wherein the rotating U-punching mechanism and the feeding mechanism are arranged at intervals along the feeding path of the carrying mechanism;

[0005] The transport mechanism includes a displacement mechanism 1, a first clamping mechanism, and a wire supporting mechanism. The first clamping mechanism and the wire supporting mechanism are arranged at the moving end of the displacement mechanism 1. The wire supporting mechanism includes a third shifting mechanism and an opening and closing mechanism at its moving end. A push block is arranged at the moving end of the opening and closing mechanism. After the first clamping mechanism clamps the workpiece 1, the displacement mechanism 1 moves the first clamping mechanism so that the clamped workpiece 1 is moved into the working range of the rotating U-punching mechanism and the feeding mechanism.

[0006] The rotating U-forming mechanism is used to bend and U-form the workpiece transported by the transport mechanism;

[0007] The feeding mechanism includes a second shifting mechanism and a second clamping mechanism at its moving end, and driven by the second shifting mechanism, the required workpiece 2 clamped by the second clamping mechanism is moved onto the bent workpiece 1 transported by the transport mechanism;

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

[0009] In this scheme, the composition and coordination relationship of each functional mechanism are designed. When in use, the wires on the junction box (workpiece one) can be U-shaped and shaped by the buckle (workpiece two), which is convenient for subsequent operations, improves the degree of automation and efficiency.

[0010] Specifically, the wire on the junction box is clamped by the first clamping mechanism, and the first clamping mechanism is moved by the displacement mechanism 1 to move the junction box and the wire into the working range of the rotating U-tying mechanism, and the rotating U-tying mechanism is used to U-tyre the wire. Then, the U-tyring junction box and the U-tyring wire are moved to the feeding mechanism, and the feeding mechanism is used to place the buckle on the bent U-tyring part of the wire, and then the wire supporting mechanism is used to respectively clip the two sides of the U-tyring part of the wire into the buckle opening, thereby completing the combination of workpiece one and workpiece two.

[0011] Furthermore, the rotary U-forming mechanism includes a first shifting mechanism, a driving mechanism, a push plate, and a fixing mechanism. The driving mechanism is arranged at the moving end of the first shifting mechanism and the push plate is arranged at the output end of the driving mechanism. A fixing mechanism is arranged on one side of the first shifting mechanism. The fixing mechanism includes a fourth shifting mechanism and a pressure plate at its moving end. The fourth shifting mechanism drives the pressure plate to press the workpiece 1 transferred by the transport mechanism. The first shifting mechanism is used to adjust the relative position of the push plate and the workpiece 1. When the push plate is in a predetermined position, the driving mechanism rotates the push plate, and the push plate is used to bend the workpiece 1 synchronously.

[0012] In this scheme, the wiring box part of workpiece one is pressed and fixed by a fixing mechanism, and the position of the push plate is adjusted by the first shifting mechanism. For example, when it is moved to a predetermined position of the wire (such as the middle position of the wire), the driving mechanism rotates the push plate so that the push plate pushes the wire to bend into a U shape. The driving mechanism stops outputting, and the first shifting mechanism can continue to move the push plate as needed. Under the push of the push plate, the end of the wire is straightened, which is convenient for clamping by the transport mechanism later.

[0013] Furthermore, the push plate includes a connecting plate and a boss. The boss is located at the bottom surface of the connecting plate and is non-concentric with the rotation center of the driving mechanism. The structure of the push plate is designed to facilitate docking with the driving mechanism and to facilitate pushing the wire to bend.

[0014] Furthermore, the first shifting mechanism includes a linear reciprocating shifting mechanism and a telescopic lifting mechanism at its moving end. A driving mechanism is longitudinally arranged at the moving end of the telescopic lifting mechanism and the output end of the driving mechanism faces downward. Reasonable design of the composition of the first shifting mechanism helps to simplify the structure and reduce costs.

[0015] Furthermore, the fourth shifting mechanism is a linear lifting type, and the fourth shifting mechanism lifts and lowers the pressure plate linearly in the longitudinal direction, has mature technology, and is easy to purchase.

[0016] Furthermore, the second shifting mechanism includes a linear reciprocating shifting mechanism 2 and a telescopic lifting mechanism 2 at its moving end. A second clamping mechanism is longitudinally arranged at the moving end of the telescopic lifting mechanism 2. Reasonable design of the composition of the second shifting mechanism helps to simplify the structure, reduce costs, and facilitate assembly. When in use, the linear reciprocating shifting mechanism 2 is used to move the horizontal position of the telescopic lifting mechanism 2, and the telescopic lifting mechanism 2 is used to adjust the longitudinal position of the second clamping mechanism.

[0017] Furthermore, it also includes a vibrating feeding mechanism, which is used to convey the second workpiece. A dividing mechanism is arranged at the discharge port of the vibrating feeding mechanism, and the dividing mechanism includes a telescopic mechanism and a material seat at its moving end. The telescopic mechanism moves the material seat horizontally back and forth. Under normal conditions, the material seat is at the discharge port and a material trough for accommodating the second workpiece is arranged at the position of the material seat facing the discharge port. The telescopic mechanism moves the material seat so that the material trough is within the working range of the second clamping mechanism. The vibrating feeding mechanism is added to facilitate the loading of the buckles, and the dividing mechanism separates the side-by-side buckles to facilitate subsequent clamping and feeding.

[0018] Furthermore, it also includes a presetting mechanism and a material unloading mechanism, wherein the presetting mechanism includes a telescopic lifting mechanism 3 and a material holder 2 at its moving end, and a material trough 2 for placing an end of a workpiece is arranged on the top surface of the material holder 2;

[0019] The unloading mechanism comprises a fifth shifting mechanism and a third clamping mechanism, and the third clamping mechanism is arranged at the moving end of the fifth shifting mechanism;

[0020] The presetting mechanism and the unloading mechanism are arranged along the feeding path of the transport mechanism, and the transport mechanism delivers the workpiece 1 at the presetting mechanism to the working range of the rotating U-punching mechanism, and the third clamping mechanism in the unloading mechanism clamps the combined workpiece 1 or workpiece 2.

[0021] When in use, the junction box is manually placed in the second material slot in the preset mechanism, and then the wire at the end of the junction box is clamped by the carrying mechanism for feeding.

[0022] Furthermore, a mounting seat is provided at the movable end of the displacement mechanism 1, and first clamping mechanisms are arranged on the mounting seat at intervals along the conveying direction of the displacement mechanism 1, and two groups of first clamping mechanisms are relatively arranged at the middle position of the mounting seat, and first clamping mechanisms are respectively arranged at the head end and the tail end of the mounting seat, and the first clamping mechanism at the head end is horizontally reciprocated by the telescopic mechanism 2 arranged on the mounting seat, and a third shifting mechanism is arranged on one side of the first clamping mechanism at the tail end, and the third shifting mechanism is a longitudinal lifting and closing mechanism; the displacement mechanism 1 reciprocates to make the first clamping mechanism at the head end move between the preset mechanism and the rotating U-making mechanism, the first clamping mechanism in the middle moves between the rotating U-making mechanism and the feeding mechanism, and the first clamping mechanism at the end moves between the feeding mechanism and the unloading mechanism, and the workpiece 1 is combined with the workpiece 2 by the wire supporting mechanism at the unloading mechanism.

[0023] Furthermore, the fifth shifting mechanism includes a linear reciprocating shifting mechanism three and a telescopic lifting mechanism four at its moving end, and a third clamping mechanism is arranged at the moving end of the telescopic lifting mechanism four.

[0024] Furthermore, it also includes a base, on which a carrying mechanism, a presetting mechanism, a rotating U-forming mechanism, a feeding mechanism, and a unloading mechanism are arranged. The presetting mechanism, the rotating U-forming mechanism, the feeding mechanism, and the unloading mechanism are arranged in sequence along the feeding path of the carrying mechanism. The base is added to centrally place various functional mechanisms to facilitate transportation and factory placement.

[0025] Furthermore, it also includes slide one and slide two, which are fixed side by side on the base, and slide one and slide two extend along the feeding path of the carrier mechanism, and the moving path of the first clamping mechanism is between slide one and slide two. During the feeding process of the carrier mechanism, slide one and slide two support workpiece one, and two slides are added to support workpiece one to improve the smoothness of operation.

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

[0042] Example 1

[0043] like Figure 1-Figure 9 As shown, in this example, the terminal box wire buckling machine includes a base 1 and various functional mechanisms, such as a preset mechanism 3, a carrying mechanism 2, a rotary U-punching mechanism 4, a feeding mechanism 5, and a unloading mechanism 6. The preset mechanism 3, the carrying mechanism 2, the rotary U-punching mechanism 4, the feeding mechanism 5, and the unloading mechanism 6 are installed on the base 1, and the preset mechanism 3, the rotary U-punching mechanism 4, the feeding mechanism 5, and the unloading mechanism 6 are arranged in sequence along the feeding path of the carrying mechanism 2.

[0044] The base 1 is a box frame type body and a bracket installed on the top surface that is connected to the corresponding functional mechanism, and the bracket supports the corresponding functional mechanism. A circuit board and other mechanisms connected to each functional mechanism are installed in the cavity of the base 1, and a display panel control mechanism can be added to connect the display panel control mechanism with the above-mentioned functional mechanisms, and the action execution 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 presetting mechanism 3 is installed near the head end of the carrier mechanism 2. The presetting mechanism 3 includes a telescopic lifting mechanism 31 and a material seat 2 32 at its moving end. The telescopic lifting mechanism 31 lifts the material seat 2 32 in the longitudinal direction. The top surface of the material seat 2 32 is formed with a material trough 2 33 for accommodating one end of a workpiece. In this example, the workpiece 1 is a junction box 11, and the material trough 2 33 can accommodate the box body of the junction box 11. The carrier mechanism 2 transports the workpiece 1 in the presetting mechanism 3 to the working range of the rotary U-making 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-making mechanism 4 includes a first shifting mechanism, a driving mechanism 44, a push plate 43, and a fixing mechanism 45. The driving mechanism 44 is installed longitudinally at the moving end of the first shifting mechanism, and the output end of the driving mechanism 44 faces downward. The driving mechanism is such as a driving motor, and the push plate 43 is installed at the output end of the driving motor. The relative position of the push plate 43 and the workpiece 1 is adjusted by the first shifting mechanism. When the push plate is in a predetermined position, the driving mechanism 44 rotates the push plate 43, and the workpiece 1 is simultaneously bent by the push plate, such as bending the wire connected to the box body in the junction box into a U shape.

[0047] For the first shifting mechanism, if the first shifting mechanism includes a linear reciprocating shifting mechanism 41 and a telescopic lifting mechanism 42 at its moving end, the linear reciprocating shifting mechanism 41 is a lead screw shifting type, the telescopic lifting mechanism 42 is a lifting cylinder, the linear reciprocating shifting mechanism 41 is horizontally arranged on a corresponding bracket in the base 1, and the moving end of the telescopic lifting mechanism 42 is longitudinally fixed with a driving mechanism 44. The longitudinal height and horizontal position of the push plate are adjusted by the first shifting mechanism, and of course other shifting mechanisms can also be selected to meet the adjustment of the horizontal and longitudinal positions.

[0048] A fixing mechanism 45 is installed at the base 1 on one side of the first shifting mechanism. The fixing mechanism 45 includes a fourth shifting mechanism 451 and a horizontally placed pressing plate 452 at its moving end. The fourth shifting mechanism 451 drives the pressing plate 452 to press the workpiece 1 transferred by the transporting mechanism 2. The fourth shifting mechanism 451 only needs to have a longitudinal lifting function, such as adjusting the position of the pressing plate 452 in a longitudinal linear manner. Common ones include a lifting cylinder, which is fixed on a corresponding bracket in the base. When the junction box body transported by the transporting mechanism 2 is below the pressing plate 452 (i.e., within the working range of the rotating U-forming mechanism), the fourth shifting mechanism 451 moves the pressing plate 452 downward to press the fixed box body, so as to facilitate and stabilize the subsequent bending and U-forming operations. Of course, other shifting mechanisms can also be used as the fourth shifting mechanism, such as two-way and three-way shifting mechanisms.

[0049] For the push plate, the push plate 43 includes a connecting plate 431 and a convex column 432. The connecting plate 431 is a flat plate, and is arranged horizontally. One end of the connecting plate 431 is fixed to the output end of the driving mechanism 44. The convex column 432 is arranged longitudinally on the bottom surface of the other end of the connecting plate 431. The convex column 432 is arranged non-concentrically with the rotation center of the driving mechanism 44. Figure 1 , Figure 2 , Figure 4 As shown, when the carrier mechanism 2 moves the junction box to the rotating U-shaped mechanism 4, the box body of the junction box 11 is in the working range of the fixing mechanism 45, and the box body is pressed and fixed by the pressing plate. At the same time, the wire in the junction box is in the working range of the push plate, and the horizontal position of the push plate 43 is adjusted by the linear reciprocating displacement mechanism 1 41, and the longitudinal position of the push plate 43 is adjusted by the telescopic lifting mechanism 1 42, so that the convex column 432 in the push plate 43 is on one side of the wire, and the driving mechanism 44 drives the connecting plate 431 to rotate horizontally, and the convex column 432 moves synchronously and pushes the wire to bend into a U shape. It is preferred to form a groove at the peripheral wall of the convex column 432, so that the groove abuts against the wire to improve stability during the bending process. In addition, after the wire is bent into a U shape, the push plate 43 can be reset by the linear reciprocating displacement mechanism 1 41, and the end of the bent wire is straight under the push of the convex column, which is convenient for the clamping of the subsequent carrier mechanism.

[0050] like Figure 1 , Figure 2 , Figure 7 As shown, in this example, the feeding mechanism 5 includes a second shifting mechanism and a second clamping mechanism 53 at its moving end. Driven by the second shifting mechanism, the required workpiece 2 clamped by the second clamping mechanism 53 is moved onto the bent workpiece 1 transported by the transport mechanism.

[0051] The second shifting mechanism includes a linear reciprocating shifting mechanism 51 and a telescopic lifting mechanism 52 at the moving end thereof. The moving end of the telescopic lifting mechanism 52 is longitudinally provided with a second clamping mechanism 53. The linear reciprocating shifting mechanism 51 is a common screw shifting type and is horizontally provided on a corresponding bracket in the base. The second clamping mechanism is a common clamping claw cylinder. The second clamping mechanism clamps the workpiece 2. The workpiece 2 is Figure 7 The buckle 12 shown is shaped like an elliptical ring as a whole and has an entrance formed on the bottom surface for the wire to enter. Both ends of the buckle 12 cavity form snap-fitting openings for engaging with the wire.

[0052] When in use, when the transport mechanism 2 transports the U-shaped junction box to the working range of the feeding mechanism 5, the second clamping mechanism 53 is moved to above the U-shaped wire part by the linear reciprocating displacement mechanism 2 51, and the position of the second clamping mechanism 53 is adjusted by the telescopic lifting mechanism 2 52. The second clamping mechanism 53 releases the buckle 12, so that the buckle falls on the U-shaped wire part, and this part of the wire enters the cavity from the entrance on 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 engaged with the buckle.

[0053] like Figure 1 , Figure 2 , Figure 6 As shown, in this example, the vibration loading mechanism 7 is located on one side of the second shifting mechanism, that is, the vibration loading mechanism 7 is arranged at the tail end of the linear reciprocating shifting mechanism 2 51. The vibration loading mechanism 7 is such as a common vibration loading plate, which can be purchased directly from the market. The vibration loading mechanism 7 is used to convey the workpiece 2.

[0054] The discharging mechanism 10 is installed at the discharging port of the vibrating feeding mechanism 7. The discharging mechanism 10 includes a telescopic mechanism 101 and a material holder 102 at its moving end. The material holder 102 is horizontally reciprocated by the telescopic mechanism 101. Under normal conditions, the material holder 102 is at the discharging port and a material trough 103 for placing the workpiece 2 is formed at the side of the end of the material holder 102 facing the discharging port. The material trough 103 includes a groove cavity for placing a buckle and a notch formed at the groove wall. The notch extends along one end face of the material holder to the other side face, and the notch is used for the clamping claw to extend into the groove cavity for clamping. For the telescopic mechanism 1, such as a common telescopic cylinder, the telescopic cylinder is installed on the corresponding bracket in the base.

[0055] When in use, if the buckles at the discharge port of the vibrating feeding mechanism are in a side-by-side state, the first buckle is transported to the material trough, and then the material seat one is moved by the telescopic mechanism one, so that the material trough is within the working range of the second clamping mechanism, the linear reciprocating displacement mechanism two cooperates with the telescopic lifting mechanism two to adjust the clamping of the second clamping mechanism, and then it is transported to the U-shaped wire, the material seat one is reset to the discharge port, and the next buckle enters the material trough, which is convenient and stable for loading.

[0056] like Figure 1 , Figure 2 , Fig.10 As shown, in this example, the unloading mechanism 6 includes a fifth shifting mechanism and a third clamping mechanism 63, and the third clamping mechanism 63 is installed at the moving end of the fifth shifting mechanism. The fifth shifting mechanism includes a linear reciprocating shifting mechanism 3 61 and a telescopic lifting mechanism 4 62, and the linear reciprocating shifting mechanism 3 61 is a common screw shifting type and is horizontally arranged on the corresponding bracket in the base 1, and the telescopic lifting mechanism 4 62 is installed at the moving end thereof in the longitudinal direction, and the third clamping mechanism 63 is installed at the moving end of the telescopic lifting mechanism 4 62. The telescopic lifting mechanism 4 is a common lifting cylinder, and the third clamping mechanism is a common cylinder clamp.

[0057] When the carrier conveys the combined workpiece 1 and workpiece 2 to the working range of the unloading mechanism 6, the linear reciprocating displacement mechanism 3 61 and the telescopic lifting mechanism 4 62 cooperate to adjust the position of the third clamping mechanism 63, such as to the position where the third clamping mechanism can clamp the wire, and the third clamping mechanism clamps a single part of the wire, or the third clamping mechanism separates the clamping jaws to clamp the U-shaped part of the wire in an outwardly expanded support manner, and then conveys it to the next station or storage box. The linear reciprocating displacement mechanism 3 extends along the feeding direction of the carrier.

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

[0059] A mounting seat 24 is fixed at the moving end of the displacement mechanism 21, and the mounting seat 24 extends along the displacement direction of the displacement mechanism 21. A first clamping mechanism 22 is installed on the mounting seat 24 at intervals along the conveying direction of the displacement mechanism 21. The first clamping mechanism is a common cylinder clamp type.

[0060] In this example, the base 1 is equipped with a preset mechanism 3, a rotating U-forming mechanism 4, a feeding mechanism 5, a material unloading mechanism 6, etc., that is, there are four workstations, and the first clamping mechanism 22 is respectively installed at the head end, the tail end and the middle position of the mounting seat 24 to reciprocately transport the material.

[0061] In order to facilitate clamping of the wires in the junction box at the preset mechanism, a telescopic mechanism 23 is installed at the head end of the mounting seat 24 for horizontal reciprocating displacement. For example, the telescopic mechanism 23 is telescoped along the feeding direction of the displacement mechanism 1 21, and a first clamping mechanism 22 is installed at the moving end of the telescopic mechanism 23 to facilitate adjustment of the position of the first clamping mechanism claws, thereby better clamping the wires.

[0062] The wires of the junction box are bent into a U shape at the rotating U-bending mechanism 4. To facilitate this configuration, two first clamping mechanisms 22 are relatively installed at the middle position of the mounting seat 24 to clamp the wires on both sides of the cavity respectively.

[0063] At the rear end of the mounting seat 24, the wire supporting mechanism is arranged opposite to the first clamping mechanism 22. After moving to the predetermined position, the wires on both sides of the U-shaped cavity are pushed into the snap-on sockets of the buckle 12 to be fixed by the action of the wire supporting mechanism, thereby completing the combination of the wires and the buckle in the junction box, and facilitating the subsequent unloading of the unloading mechanism. For the wire supporting mechanism, if the wire supporting mechanism includes a third shifting mechanism 25 and an opening and closing mechanism 26 at its moving end, the third shifting mechanism 25 is a telescopic lifting type, such as a lifting cylinder. The third shifting mechanism 25 is fixed to the mounting seat 24 along the longitudinal direction to lift and lower the opening and closing mechanism 26 in the longitudinal direction. Of course, two-way or three-way shifting mechanisms can also be selected to meet the adjustment of the longitudinal position. The opening and closing mechanism 26 is a common clamping cylinder, and a push block 27 is fixed at the moving end of the cylinder. The push block has a variety of configurations, and it only needs to have a longitudinal part. When moving to the side, it can push the corresponding wire part into the snap-on socket of the buckle. The preferred configuration of the push block 27 is as follows Figure 8 As shown, the two push blocks are symmetrical, and the upper part is cross-shaped after being combined. The upper part of a single push block is L-shaped. The horizontal end of the push block 27 can move the wire upward to adjust the position, and the vertical end of the push block can push the corresponding wire part into the buckle of the buckle to improve the stability of operation.

[0064] Specifically, when in use, the displacement mechanism 21 reciprocates to move the first clamping mechanism 22 at the head end between the preset mechanism 3 and the rotary U-tying mechanism 4, clamping the wire of the junction box at the preset mechanism, and then transporting it to the working range of the rotary U-tying mechanism, and the rotary U-tying mechanism is used to perform U-tying on the wire of the junction box;

[0065] The first clamping mechanism 22 in the middle is moved between the rotating U-bending mechanism 4 and the feeding mechanism 5, and the two first clamping mechanisms clamp the wires of the junction box that have been U-bent, and move from the rotating U-bending mechanism to the working range of the feeding mechanism, and the feeding mechanism places 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 unloading mechanism 6, and the first clamping mechanism is used to move the junction box with the buckle installed from the feeding mechanism to the working range of the unloading mechanism. Then, the third shifting mechanism in the wire support mechanism is used to move the opening and closing mechanism upward, so that the push block is in the U-shaped cavity of the wire. The opening and closing mechanism separates the push blocks, that is, the two push blocks move to the side and synchronously push the corresponding wire part into the buckle of the buckle to complete the combination. Then, the fifth shifting mechanism in the unloading mechanism is used to adjust the position of the third clamping mechanism, and the third clamping mechanism is used to clamp the wire at the junction box, and then the fifth shifting mechanism is used to move the third clamping mechanism to the desired position.

[0067] In addition, in order to improve the running stability, a slide 1 8 and a slide 2 9 can be added, such as Figure 1 , Figure 2 As shown, slide one 8 and slide two 9 are fixed on the base 1 side by side, slide one 8 and slide two 9 extend along the feeding path of the carrying mechanism 2 and the moving path of the first clamping mechanism 22 is between slide one 8 and slide two 9. The heights of slide one and slide two are adjusted according to needs, such as being flush with the clamping claw end of the first clamping mechanism, or slightly higher or slightly lower than the clamping claw end. When in use, if the wires of the junction box are clamped and moved by the carrying mechanism, the box body of the junction box is supported by slide two, and the box body moves along slide two. When it moves to the bottom of the pressure plate, the pressure plate at the fixing mechanism moves down to fix the box body, and the wires of the junction box are supported by slide one and move along slide one.

[0068] Of course, the preset mechanism, vibration feeding mechanism and unloading mechanism can be removed according to needs and replaced manually.

[0069] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
