Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic junction box production. Specifically, it discloses a photovoltaic junction box cable shaping machine and a shaping method. Background Art

[0002] After the photovoltaic junction box is assembled, its finished product mainly includes three parts: a box body, cables, and connectors. Figure 1 There is a schematic structure of a photovoltaic junction box shown. When the finished photovoltaic junction box undergoes the next process, it needs to be packaged to prevent the cables from being messy and affecting subsequent production and installation. Currently, there are mainly two packaging methods for the cables on the photovoltaic junction box: 1. Cable winding bundling method: Wind the cables of the photovoltaic junction box into a circle, and then tie them together with ropes or straps. This method is suitable for longer cables on the photovoltaic junction box, but not for shorter cables. 2. Cable bending bundling method: Bend the cables of the photovoltaic junction box into a U shape, and then use a buckle to clamp the two sides of the bent U shape. This method is suitable for shorter cables on the photovoltaic junction box, but not for longer cables.

[0003] Regarding the above-mentioned packaging of the cables on the photovoltaic junction box, there is a manual operation method. Although the subjective initiative of the personnel is strong and they can adjust the corresponding manual operation methods according to different customer requirements or different product requirements, the automation degree is low, the efficiency is low, and it is not conducive to batch automatic production operations.

[0004] Therefore, other technicians have designed automated machines to replace manual labor to complete the cable bending. The machine automatically bends the cables and fixes the cables with a buckle such as the one disclosed in the Chinese patent with the patent number CN209805765U in the prior art. For example, the Chinese patent with the patent number 202421112780.4 in the prior art discloses a wire harness bending and buckling machine, which can realize the automatic bending and buckle installation of cables.

[0005] However, different users have different requirements for the equipment. For example, some only want to bend and buckle the packaging of the photovoltaic junction box with short cables, and only need to be able to convey the photovoltaic junction box with long cables without packaging, meeting the working requirements of photovoltaic junction boxes with different cable lengths; for example, regarding the corresponding situation of the hook part of the buckle with the front and back sides of the upper box body of the photovoltaic junction box, some need them to be in the same direction, and some need them to be in the opposite direction, and whether they are in the same direction will also affect the bending direction, that is, whether to bend the cable from the left side of the cable or from the right side of the cable, and the width between the U-shaped cables after bending also needs to meet certain requirements.

[0006] Although the above-mentioned prior art solution, "a wire harness bending buckle machine", can replace traditional manual operations, its designed solution has a low applicability, complex execution actions, and the execution action process cannot be easily adjusted or changed, unable to meet the usage requirements of different users, unable to perform adapted processes for photovoltaic junction boxes with different cable lengths, and unable to adjust the correspondence between the front and back sides of the upper box body and the front and back sides of the buckle on the photovoltaic junction box, that is, it cannot achieve multi-purpose use with one machine. Summary of the Invention

[0007] The object of the present invention is to provide a photovoltaic junction box cable shaping machine and a shaping method, which have a simple structure, diverse application methods, multi-purpose use with one machine, and strong compatibility.

[0008] The first technical solution is as follows: A photovoltaic junction box cable shaping machine, on the equipment table, there are arranged side by side a first linear reciprocating motion mechanism and a second linear reciprocating motion mechanism. Each of the first linear reciprocating motion mechanism and the second linear reciprocating motion mechanism is equipped with a handling group that can clamp and convey the photovoltaic junction box of the previous process to the next process. The photovoltaic junction box is conveyed in a posture perpendicular to the conveying direction. Among them, along the conveying path of the first linear reciprocating motion mechanism, there are successively arranged: A loading station for receiving the photovoltaic junction box and correcting its conveying posture; An adjustment station, including: a positioning component for positioning the box body of the photovoltaic junction box, a flipping component that can drive the positioning component to rotate so as to achieve a 180° flip of the box body, and a first displacement module that drives the flipping component to move in a direction perpendicular to the conveying path of the first linear reciprocating motion mechanism. The first displacement module can send the photovoltaic junction box from the first linear reciprocating motion mechanism to the second linear reciprocating motion mechanism; A bending and shaping station, including: two pressing components arranged side by side and capable of working independently of each other to position the box body, a bending center column, a rotating power component that can drive the axial rotation of the bending center column, a bending roller connected to the bending center column through an intermediate arm, a second displacement module that drives the rotating power component to move in a direction perpendicular to the conveying path of the first linear reciprocating motion mechanism, and a holding module for maintaining the deformation of the cable of the photovoltaic junction box bent into a U shape. The holding module is arranged on the first linear reciprocating motion mechanism, and the cable of the photovoltaic junction box will be located between the bending center column and the bending roller; An installation station, including: a feeding component that intermittently provides buckles, a picking component that picks up materials from the position of the feeding component, a pressing component that positions the cable bent into a U shape, a third displacement module that places the buckle on the picking component in a downward posture on the cable bent into a U shape, and a spreading module that externally clips the two sides of the cable bent into a U shape into the two ends of the buckle respectively. The spreading module is arranged on the first linear reciprocating motion mechanism; The blanking station is used to receive the shaped photovoltaic junction box and blank it.

[0009] In this solution, multiple functional stations are designed and with the interaction of each station, the purpose of bending and buckling and shaping the cables on the photovoltaic junction box can be achieved, and the orderly packaging work can be completed.

[0010] Furthermore, the adjustment station also has a guiding module for guiding the position of the cables of the photovoltaic junction box. The guiding module includes a guiding jaw cylinder part and two guiding wheels driven by the guiding jaw cylinder part to move closer to or away from each other left and right. The outer peripheral surface of the guiding wheel has a V-shaped groove that can accommodate the cable.

[0011] Specifically, when producing a photovoltaic junction box with a longer cable length, the photovoltaic junction box will be dragged by the first displacement module towards the direction of the second linear reciprocating motion structure. During the dragging process of the photovoltaic junction box, its cable will be constrained by the guiding module, thus avoiding the problem that the cable swings randomly left and right due to too large an action amplitude during the conveying process of the photovoltaic junction box.

[0012] Even further, in the adjustment station: the positioning component includes a positioning jaw cylinder part and two clamping plate bodies driven by the positioning jaw cylinder part to move closer to or away from each other up and down; the flipping component includes a rotating cylinder part connected to the positioning jaw cylinder part. After clamping the box body of the photovoltaic junction box through the positioning component, if there is a requirement to flip the box body, the flipping component can be used to drive the positioning component and the photovoltaic junction box to flip 180° together, and the execution action is simple.

[0013] Furthermore, in the bending and shaping station: the position of the bending roller on the middle arm is adjustable. Designing the position of the bending roller to be adjustable can adjust the distance between the bending roller and the bending center column, so as to adjust the spacing size of the cable bent into a U shape.

[0014] Furthermore, the loading station includes: A loading bracket; A receiving table, which is arranged in the middle of the loading bracket, and there is a slope on one side of it; A box body clamping block, which is arranged on the loading bracket through a lifting cylinder. The bottom end of the box body clamping block is recessed inward in the middle to form a receiving groove that can adapt to the width of the box body, and inclined surfaces that slope outward are formed on both sides of the receiving groove; A pushing body, which is located below the receiving table and is arranged on the loading bracket through a pushing cylinder. A through groove through which the pushing body can pass up and down is opened on the receiving table.

[0015] Specifically, after the box body of the photovoltaic junction box arrives at the material receiving table, the pushing body is pushed upward to contact the box body until the box body is pushed into the receiving groove, and finally the box body is pressed down to the material receiving table by the box body clamping block to complete the automatic centering and positioning of the box body of the photovoltaic junction box, so that the handling group on the first linear reciprocating motion mechanism can perform corresponding operations on the photovoltaic junction box at this position.

[0016] Further, in the installation station: the feeding assembly includes: A feeding bracket, with two protrusions on both sides of its top end which are jointly connected to a limiting top plate, and a convex block is provided in the middle of its top end with a certain distance reserved from the limiting top plate; A placing block, which is arranged against the side of the convex block and has the same height as the convex block. There are spaces on both sides and above the placing block; A lifting fork body, which is arranged on the feeding bracket through a lifting cylinder and is located outside the placing block to lift the buckle on the placing block; The picking component includes: A picking jaw cylinder, which drives two picking jaw blocks that can approach or separate from each other. A branch protrudes in the middle of the bottom end of the picking jaw block; A butting plate body, which is arranged on the picking jaw cylinder. Its extending direction is perpendicular to the clamping direction of the picking jaw cylinder, and the middle part of it is located between the two picking jaw blocks. There is a distance between the plane of the bottom end face of the butting plate body and the plane of the bottom end face of the picking jaw block.

[0017] Specifically, a single buckle automatically flows into the position of the placing block with the hook part facing downwards, and the lifting fork body lifts the buckle upwards to achieve separation, so that the picking component can pick up the buckle.

[0018] Further, in the bending and shaping station: the holding module includes a holding jaw cylinder and two holding arms driven by the holding jaw cylinder that can approach or separate from each other left and right. A limiting groove for accommodating the cable is provided on the inner wall of the holding arm.

[0019] Specifically, the two holding arms approach from both sides to the two sides of the cable bent into a U shape, and the cable automatically snaps into the limiting groove, and the holding module realizes the action of maintaining the shape of the U-shaped cable.

[0020] Further, in the first linear reciprocating motion mechanism: the second handling group and the holding module are respectively arranged on the first linear reciprocating mechanism through stroke fine-tuning cylinders. The stroke fine-tuning cylinder can provide precise motion control and repeat positioning, can quickly adapt to changes in the corresponding station, reduces the downtime, and improves the production efficiency.

[0021] Further, in the installation station: the expanding module includes an expanding cylinder, two support rod parts driven by the expanding cylinder to move away from or close to each other left and right, and a lifting cylinder part for driving the expanding cylinder to move up and down.

[0022] Specifically, the two support rod parts are driven to move outwards respectively to apply a force to the cable, so as to push the cable into the hook part of the buckle, realizing the installation of the buckle.

[0023] The second technical solution is as follows: A method for shaping the cables of a photovoltaic junction box, which is realized by using the above-mentioned photovoltaic junction box cable shaping machine. The method includes the following steps: ① Feeding: The photovoltaic junction box is normally conveyed from the previous station to the feeding station, and its conveying posture is corrected by the feeding station, so that the photovoltaic junction box can be conveyed in a posture perpendicular to the conveying direction; ② Intermediate adjustment: The first linear reciprocating motion mechanism transports the photovoltaic junction box from the feeding station to the adjustment station, and performs the following actions according to the corresponding production requirements: Action 1: If the cable of this photovoltaic junction box is relatively long, it is sent to the position of the second linear reciprocating motion mechanism by the first displacement module, and the second linear reciprocating motion mechanism directly discharges this photovoltaic junction box; Action 2: If the cable of this photovoltaic junction box is relatively short and there is no production requirement for the consistency between the buckle direction and the box body direction, the flipping component does not work, the front side of the box body of the photovoltaic junction box faces upwards, and the first linear reciprocating motion mechanism transports this photovoltaic junction box to the bending and shaping station; Action 3: If the cable of this photovoltaic junction box is relatively short and there is a production requirement for the consistency between the buckle direction and the box body direction, the flipping component flips the box body of this photovoltaic junction box by 180°, so that the back side of the box body faces upwards, and the first linear reciprocating motion mechanism transports this photovoltaic junction box to the bending and shaping station; ③ Bending and shaping: If Action 2 is executed at the adjustment station, the photovoltaic junction box is pressed and fixed by the pressing component on the right, and the bending center column drives the bending roller to rotate from the right side of the cable through the middle arm. During the rotation, the bending roller will force the cable to bend leftward in a U shape; if Action 3 is executed at the adjustment station, the photovoltaic junction box is pressed and fixed by the pressing component on the left, and the bending center column drives the bending roller to rotate from the left side of the cable through the middle arm. During the rotation, the bending roller will force the cable to bend rightward in a U shape; Regardless of the bending direction, the connector at the end of the cable after the U-shaped bending is finally located on the same side of the box body; After the cable is bent, the deformation is maintained by the maintaining module and is conveyed to the installation station under the action of the first linear reciprocating motion mechanism; ④ Buckle installation: The clamping component holds and fixes the U-shaped part of the cable, and the feeding component intermittently provides the buckle. The buckle is always facing upward, and the buckle is placed on the U-shaped cable through the picking component and the third displacement module. The module is kept separate from the cable, and the cable is squeezed into the hook part of the buckle by the opening module; ⑤ Unloading: The open module transports the photovoltaic junction box with the completed snap-on installation to the unloading station under the action of the No. 1 linear reciprocating motion mechanism for unloading.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the present scheme designs multiple functional workstations and relies on the mutual cooperation between the workstations to achieve the purpose of bending and snap-fitting the cables on the photovoltaic junction box, complete the orderly packaging work, and can adapt to the production needs of two types of photovoltaic junction boxes with different cable lengths. It can also perform action instructions such as flipping the photovoltaic junction box, adjusting the bending direction, and adjusting the snap direction according to the corresponding user requirements. The action execution principle is simple, truly realizing one machine with multiple uses, and has a wide range of applications.

[0025] 1. The design of the loading station can realize the accurate loading of the photovoltaic junction box, and can automatically correct the placement of the photovoltaic junction box body, so that the placement of the cables on the photovoltaic junction box in the loading state is perpendicular to the conveying direction.

[0026] 2. The design of the adjustment station is very critical, and different action instructions can be implemented according to different production requirements; Action 1: Pull the photovoltaic junction box with longer cables that does not require bending and snap-on installation from the No. 1 linear reciprocating motion mechanism to the No. 2 linear reciprocating motion mechanism; Action 2: Under the premise of the photovoltaic junction box with shorter cables, the photovoltaic junction box that needs to be turned over will be turned over 180°. The purpose of turning over is to be able to flexibly adjust the snap-on direction to be consistent with the front or back of the box body according to two assembly requirements.

[0027] 3. The design of the bending and shaping station can work in coordination with the adjustment station, that is, if the photovoltaic junction box of the shorter cable does not perform the flipping action at the adjustment station, then the bending and shaping station will perform the normal bending action on the photovoltaic junction box of the shorter cable; on the contrary, if the photovoltaic junction box of the shorter cable performs the flipping action, its placement needs to be adjusted, and the rotation direction of the bending roller on the bending and shaping station will also move in the opposite direction to adjust the bending work direction. Regardless of whether the front or back of the box is facing up, the final bending direction of the cable is the same (that is, the relative position of the connector and the box body remains unchanged).

[0028] 4. The design of the installation station is not affected by the adjustment station and the bending and shaping station. The buckle supplied by the installation station always remains face up, that is, the feeding posture of the buckle is always consistent with the picking and placing posture. There is no need to adjust the placement direction of the buckle. The corresponding situation between the hook part of the buckle and the front and back sides of the box body can be achieved only by the cooperation of the adjustment station and the bending and shaping station.

[0029] 5. The two circulating conveying lines of the first linear reciprocating motion mechanism and the second linear reciprocating motion mechanism work independently, with good flexibility and no errors. The first linear reciprocating motion mechanism is only for transporting the photovoltaic junction boxes with shorter cables, and the second linear reciprocating motion mechanism is only for transporting the photovoltaic junction boxes with longer cables.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] This embodiment proposes a wire and cable shaping machine for photovoltaic junction boxes, aiming at photovoltaic junction boxes. Usually, a photovoltaic junction box 100 has a box body 100a, a wire and cable 100b, and a connector 100c. In the initial state, the three are almost in a straight line. The ultimate goal of this embodiment is to bend the wire and cable in a straight state on the photovoltaic junction box into a U shape and use a buckle 200 to clamp and fix both sides of the U shape, and finally form as Figure 1The schematic diagram of the packaging shown

[0033] Please refer to Figure 2 As shown, on the equipment table 10, a first linear reciprocating motion mechanism 1 and a second linear reciprocating motion mechanism 2 are arranged side by side at intervals. The first linear reciprocating motion mechanism 1 and the second linear reciprocating motion mechanism 2 are both arranged along the length direction of the equipment. And the position of the second linear reciprocating motion mechanism 2 is above the first linear reciprocating motion mechanism 1. The first linear reciprocating motion mechanism 1 and the second linear reciprocating motion mechanism 2 can both achieve left - right reciprocating motion relative to the equipment table. For example, relying on the action of a cylinder or other driving parts, first move from the previous working station to the subsequent working station, and then move in the reverse direction from the subsequent working station back to the previous working station, and repeat such actions. Each of the first linear reciprocating motion mechanism 1 and the second linear reciprocating motion mechanism 2 is equipped with a handling group 11 that can clamp and convey the photovoltaic junction box of the previous process to the next process. The handling groups are arranged in an array. Among them, the first linear reciprocating motion mechanism is mainly used for the photovoltaic junction box with a shorter cable length, while the second linear reciprocating motion mechanism is mainly used for the photovoltaic junction box with a longer cable length. They work independently. The cable of the photovoltaic junction box with a shorter cable length is generally 200mm - 400mm, and the cable of the photovoltaic junction box with a longer cable length generally exceeds 400mm.

[0034] It should be noted that during the conveying process of the photovoltaic junction box 100, it is conveyed in a posture perpendicular to the conveying direction, that is, the cable 100b of the photovoltaic junction box 100 is perpendicular to the conveying direction of the first linear reciprocating motion mechanism 1 (the second linear reciprocating motion mechanism 2). Above the equipment table 10, two product flow plates 8 are arranged along its length direction. One of the product flow plates 8 is between the first linear reciprocating motion mechanism 1 and the second linear reciprocating motion mechanism 2, and the other product flow plate 8 is below the first linear reciprocating motion mechanism 1.

[0035] Among them, a loading station 3, an adjustment station 4, a bending and shaping station 5, an installation station 6, and an unloading station 7 are sequentially arranged along the conveying path of the reciprocating motion mechanism 1 of the first straight line. The design of the loading station 3 is mainly to receive the photovoltaic junction box from the previous process and correct the conveying posture of the photovoltaic junction box (make the cable perpendicular to the conveying direction, that is, the box body is upward and the connector is downward); the design of the adjustment station 4 is to meet different production requirements, such as different production requirements for photovoltaic junction boxes with shorter cable lengths and longer cable lengths, such as the production requirement of whether to turn over the box body of a photovoltaic junction box with a shorter cable length; the design of the bending and shaping station 5 is mainly to bend the cable of the photovoltaic junction box with a shorter cable length into a U shape, which can be bent from left to right or from right to left; the design of the installation station 6 is mainly to use a buckle to clamp the U-shaped bent cable to form a package, and the hook part of the buckle is always downward; the design of the unloading station 7 is mainly to convey the photovoltaic junction box that has been bent and fixed with a buckle to the next process.

[0036] Combined with Figure 3 As shown. The loading station 3 includes: a loading bracket 31 arranged on the equipment table 10 in a vertical posture, a receiving table 32 arranged in the middle of the loading bracket 31 in a horizontal posture, a box body clamping block 33 movably arranged on the upper part of the loading bracket 31, and a pushing body 34 movably arranged on the lower part of the loading bracket 31.

[0037] Specifically, a slope 321 is arranged on one side of the receiving table 32 so that the box body 100a of the photovoltaic junction box 100 can pass through and flow onto the surface of the receiving table 32; the box body clamping block 33 is movably arranged on the upper part of the loading bracket 31 through a lifting cylinder 35. An accommodating groove 331 that is vertically and horizontally communicated is recessed inward at the middle position of the bottom end of the box body clamping block 33. The accommodating groove 331 can accommodate the box body 100a of the photovoltaic junction box 100, and inclined surfaces 332 that incline outward are respectively formed on two side edges of the accommodating groove 331; the pushing body 34 is located below the receiving table 32. The pushing body 34 is movably arranged on the lower part of the loading bracket 31 through a pushing cylinder 36, and a through groove 322 that is vertically and horizontally penetrated is opened on the receiving table 32. The pushing body 34 can freely pass up and down through the through groove 322.

[0038] Execution actions of the loading station 3: After the box body 100a of the photovoltaic junction box 100 arrives at the surface of the receiving table 32 via the ramp 321, first, the lifting cylinder 35 controls the box body clamping block 33 to move downward close to the box body 100a, so that the box body clamping block 33 stops at a position slightly above the box body 100a. Then, the pushing cylinder 36 controls the pushing body 34 to move upward through the through slot 322 until the box body 100a is jacked up, so that part of the box body is pushed into the receiving groove 331 at the bottom end of the box body clamping block 33. Finally, the box body clamping block 33 presses the box body 100a onto the surface of the receiving table 32, which is equivalent to completing the automatic centering work of the box body of the photovoltaic junction box. In this way, it is convenient for the handling group 11 on the first linear reciprocating motion mechanism 1 to perform the corresponding handling work on the photovoltaic junction box at the loading station.

[0039] Combined Figure 4 As shown. The adjustment station 4 includes: a positioning component 41 for positioning the box body 100a of the photovoltaic junction box 100, a flipping component 42 that can drive the positioning component 41 to rotate to achieve a 180° flipping of the box body, and a first displacement module 43 that drives the flipping component 42 to move in a direction perpendicular to the conveying path of the first linear reciprocating motion mechanism 1. The first displacement module 43 can send the photovoltaic junction box from the first linear reciprocating motion mechanism 1 to the second linear reciprocating motion mechanism 2.

[0040] Specifically, the positioning component 41 includes a positioning jaw cylinder part 411 and two clamping plate bodies 412 that can be driven by the positioning jaw cylinder part 411 to approach or move away from each other up and down. In this way, the clamping and positioning effect of the box body 100a of the photovoltaic junction box is achieved through the two clamping plate bodies 412; the flipping component 42 includes a rotary cylinder part 421 connected to the positioning jaw cylinder part 411. In this way, the purpose of 180° up and down flipping of the positioning component 41 is achieved by the rotary cylinder part 421; the first displacement module 43 is a common linear displacement module, which is used to control the flipping component and the positioning component to move back and forth together.

[0041] Execution actions of the adjustment station 4: First of all, conventionally, it is possible to rely on manual judgment to determine the length of the cable of the photovoltaic junction box transported to the adjustment station (the length of the cable can be clearly seen by the naked eye, and of course, a machine vision recognition system can also be used). For a photovoltaic junction box with a longer cable length, the positioning component 41 clamps the box body, but the flipping component 42 does not work. The first displacement module 43 controls the positioning component 41 to drive the photovoltaic junction box to move towards the second linear reciprocating motion mechanism 2. Finally, the handling group 11 on the second linear reciprocating motion mechanism 2 intermittently transfers this photovoltaic junction box (with a longer cable length) to the subsequent blanking process, and there is no need to perform subsequent bending and buckle installation work on this equipment.

[0042] On the contrary, for a PV junction box with a short cable length, the positioning component 41 is used to clamp the box body, and the first displacement module 43 does not work. If the packaging of the PV junction box requires that the hook part 210 of the buckle 200 faces the same direction as the front of the box body 100a, the box body 100a at the positioning component 41 needs to be turned over 180° up and down by the turning component 42 so that the back of the box body 100a faces up. If the packaging work does not require the hook part 210 of the buckle 200 to face the same direction as the front of the box body 100a, the turning component 42 does not work, and the PV junction box is transported to the next working station.

[0043] The design of the adjustment station 4 is very important. It functions as a transfer and switching station, which can not only meet the bending and packaging production requirements of PV junction boxes with short cable lengths, but also naturally meet the intermittent feeding requirements of PV junction boxes with long cable lengths. Moreover, it can also meet the different requirements of users for whether the buckle orientation can match the front of the box body, which greatly saves the cost and time of adjusting and modifying the subsequent station design.

[0044] Furthermore, a guiding module 44 for guiding the position of the cable 100b of the PV junction box 100 is also designed at the adjustment station 4. The guiding module 44 includes a guiding jaw cylinder part 441 and two guiding wheels 442 that can move closer to or away from each other left and right driven by the guiding jaw cylinder part 441. The outer peripheral surface of the guiding wheel 442 has a V-shaped groove that can accommodate the cable. During the production of a PV junction box with a long cable length, the PV junction box will be dragged by the first displacement module towards the direction of the second linear reciprocating motion structure. During the dragging process of the PV junction box, its cable will be constrained by the guiding module and pass between the two guiding wheels, thus avoiding the problem that the cable swings randomly left and right due to excessive movement amplitude during the transportation of the PV junction box.

[0045] Combined Figure 5 As shown in the figure. The bending and shaping station 5 includes: a pressing component 51, a bending center column 52, a rotating power component 53, bending rollers 55, a second displacement module 56, and a holding module 57.

[0046] Two pressing components 51 are designed. These two pressing components 51 are arranged side by side left and right and can work independently of each other. The pressing component 51 is mainly composed of a pressing plate and a pressing cylinder. The pressing cylinder drives the pressing plate to move downward to achieve the effect of pressing and fixing the box body of the photovoltaic junction box. The purpose of designing the pressing component 51 into two left and right ones is to match the adjustment station. If the box body 100a of the photovoltaic junction box is not turned over by 180° at the adjustment station 4, the right pressing component 51 will achieve the pressing and fixing of the box body 100a. On the contrary, if the box body 100a is turned over by 180° at the adjustment station 4, the left pressing component 51 will achieve the pressing and fixing of the box body 100a. Whether to use the left or right pressing component 51 will affect the U-shaped bending direction of the cable next.

[0047] The rotary power component 53 can drive the bending center column 52 to rotate axially with its center as the rotation axis. The rotary power component 53 and the bending center column 52 are both arranged above the equipment table 10; the second displacement module 56 can not only drive the rotary power component 53 to move back and forth, but also drive the rotary power component 53 to move up and down. That is, the second displacement module 56 belongs to a Y-Z two-axis linear displacement module.

[0048] The bending roller 55 is connected to the side of the bending center column 52 by means of a horizontal intermediate arm 54. The bending roller 55 can rotate together with the bending center column 52, that is, the bending roller 55 rotates around the bending center column 52. If the box body 100a of the photovoltaic junction box is not turned over by 180° at the adjustment station 4, the right pressing component 51 will achieve the pressing and fixing of the box body 100a. At this time, the front of the box body 100a is facing up, and the bending center column 52 is located on the left side of the cable 100b. That is, the cable 100b of the photovoltaic junction box will be between the bending center column 52 and the bending roller 55. The bending center column 52 drives the bending roller 55 to rotate from the right side of the cable 100b through the intermediate arm 54. During the rotation, the bending roller 55 will force the cable 100b to bend left in a U shape; on the contrary, if the box body 100a is turned over by 180° at the adjustment station 4, the left pressing component 51 will achieve the pressing and fixing of the box body 100a. At this time, the back of the box body 100a is facing up, and the bending center column 52 is located on the right side of the cable 100b. That is, the cable 100b of the photovoltaic junction box is also between the bending center column 52 and the bending roller 55. The bending center column 52 drives the bending roller 55 to rotate from the left side of the cable 100b through the intermediate arm 54. During the rotation, the bending roller 55 will force the cable 100b to bend right in a U shape.

[0049] Regardless of the bending direction, the connector 100c at the end of the cable 100b after the final U-shaped bending is always on the same side of the box body 100a. For example, it is on the left side of the box body placed with the front side facing up, to ensure the consistency of the packaged product.

[0050] To further meet the needs of different users, the position of the bending roller 55 on the middle arm 54 is adjustable, so that the distance between the bending roller and the bending center column can be flexibly adjusted, thereby changing the distance between the U-shaped loops after the cable is bent into a U shape.

[0051] A possible design solution is as Figure 6 shown. A distance adjustment groove 541 is provided on the middle arm 54 along its length direction, and the top of the bending roller 55 is movably arranged in the distance adjustment groove 541 through a screw 551. A fastening nut 552 that can play a role in fixing the screw is provided at the lower part of the screw 551. The diameter of the upper part of the screw 551 is larger than the width of the distance adjustment groove 541. After adjusting the distance between the bending roller 55 and the bending center column 52, the fastening nut 552 is screwed to fix the screw 551 at the set position.

[0052] The holding module 57 is mainly used to maintain the deformation of the cable 100b bent into a U shape, so that the cable on the photovoltaic junction box can always maintain the U-shaped bending posture during handling. The holding module 57 is arranged on the first linear reciprocating motion mechanism 1 and is arranged in an array with the handling group. The holding module 57 mainly includes a holding jaw cylinder 571 and two holding arms 572 that can approach or move away from each other left and right driven by the holding jaw cylinder 571. A limiting groove 573 for accommodating the cable is provided on the inner wall of the holding arm 572.

[0053] The execution action of the holding module 57: The holding jaw cylinder 571 controls the two holding arms 572 to approach both sides of the cable 100b bent into a U shape from both sides. The cable bent into a U shape has a certain elasticity. When the bending roller 55 is separated from the cable 100b, the two sides of the cable will automatically snap into the limiting grooves 573 on the inner sides of the holding arms 572 under the elastic action. Finally, the holding module 57 realizes the action of maintaining the U-shaped cable form.

[0054] Combined with Figure 7 、 Figure 8 and Figure 9 shown. The installation station 6 includes: a feeding component 61, a picking component 62, a pressing component 63, a third displacement module 64, and a spreading module 65.

[0055] The feeding component 61 is mainly used to intermittently provide the buckles in an orderly manner and can be used in cooperation with a vibrating bowl. Specifically, it includes: a feeding bracket 611, a placing block 614, and a lifting fork body 615; both sides of the top of the vertically installed feeding bracket 611 bulge upward, and a limiting top plate 612 is jointly connected between the two bulges. A convex block 613 is arranged at the middle position between the two bulges, and a certain distance is reserved between the convex block 613 and the limiting top plate 612. This distance should not be less than the thickness of the buckle. The buckles flowing out from the external vibrating bowl can be sent between the limiting top plate 612 and the convex block 613; the placing block 614 is arranged against the front side of the convex block 613 and has the same height as the convex block 613. Spaces are left on both sides and above the placing block 614. The buckles flowing out from the external vibrating bowl are first sent between the limiting top plate 612 and the convex block 613, and then a single buckle lands on the placing block 614 with its top facing upward; the lifting fork body 615 is arranged on the feeding bracket 61 in a vertically movable manner through a lifting cylinder 616. The lifting fork body 615 is located outside the placing block 614, and its function is to lift the buckles 200 on the placing block 614 upward so that the picking component 62 can pick up the buckles.

[0056] The picking component 62 includes: a picking jaw cylinder 621, picking jaw blocks 622, and an abutting plate body 624; there are two picking jaw blocks 622 respectively arranged on the two output ends of the picking jaw cylinder 621. The two picking jaw blocks 622 are driven by the picking jaw cylinder 621 to approach or move away from each other. A branch 623 protrudes downward in the middle of the bottom end of the picking jaw block 622. The branch 623 plays a role in guiding and restricting, so as to pick up the buckles 200 from the feeding component 61; the abutting plate body 624 is arranged on the picking jaw cylinder 621. Its extending direction is perpendicular to the clamping direction of the picking jaw cylinder 621, and the middle part of the abutting plate body 624 is located between the two picking jaw blocks 622. A distance is reserved between the plane of the bottom end face of the abutting plate body 624 and the plane of the bottom end face of the picking jaw block 622. The abutting plate body 624 is used to contact the top end face of the buckle 200. The distance between the plane of the bottom end face of the abutting plate body 624 and the plane of the bottom end face of the picking jaw block 622 is not less than the thickness of the buckle 200. By means of the abutting plate body, buckles of various lengths can be compatible, and the picked buckles are always in the posture with the hook part facing downward.

[0057] The design of the pressing component 63 is mainly to stably press the U-shaped bent end of the bent cable on the equipment table surface for the subsequent buckle installation work. The pressing component is mainly composed of a pressing cylinder and a pressing block, and the structural design is simple.

[0058] The third displacement module 64 is a YZ dual-axis linear displacement module. The function of the third displacement module is to control the material taking component 62 to move back and forth between the material feeding component 61 and the photovoltaic junction box cable in the clamping component 63, and place the clamped buckle 200 on the cable 100b with the hook portion 210 facing downward, and make the two hook portions 210 both on the outside of the cable 100b. At this time, the holding module on the No. 1 linear reciprocating motion mechanism moves the photovoltaic junction box with the cable bent into a U shape to the installation station. After the material taking component places the buckle on the cable, the holding module is separated from the cable. The cable bent into a U shape will expand outward on both sides under the natural elastic stretch until part of it is stuck in the entrance of the hook portion on the buckle. At this time, it is equivalent to completing the pre-positioning action of the buckle and the cable.

[0059] The opening module 65 mainly includes an opening cylinder 651, two support rods 652 driven by the opening cylinder 651 to move away from or close to each other, and a lifting cylinder 653 driving the opening cylinder 651 to move up and down. After the buckle and the cable are pre-positioned, the No. 1 linear reciprocating motion mechanism drives the opening module to move to the U-shaped ring of the cable, and the lifting cylinder lifts the two support rods upward, and drives the two support rods to move outward respectively through the opening cylinder until each contacts an inner edge of the cable, and the opening cylinder continues to work until the support rod completely squeezes the cable into the hook part of the buckle, completing the installation of the buckle, and finally the opening module on the No. 1 linear reciprocating motion mechanism moves the packaged photovoltaic junction box to the unloading station.

[0060] The unloading station 7 is mainly composed of a multi-axis linear module and a pneumatic clamping claw to clamp the packaged photovoltaic junction box and send it to the subsequent process.

[0061] Combination Figure 10 As shown. Two transport groups 11, a holding module 57, and an opening module 65 are arranged in an array from front to back on the No. 1 linear reciprocating motion mechanism 1. The No. 1 linear reciprocating motion mechanism 1 drives these four modules to move left and right synchronously. The first two transport groups 11 correspond to the transport work of the loading station 3 and the adjustment station 4 respectively. The second transport group 11 and the holding module 57 are each arranged on the No. 1 linear reciprocating motion mechanism 1 through a stroke fine-tuning cylinder 12. That is to say, the positions of the second transport group 11 and the holding module 57 on the No. 1 linear reciprocating motion mechanism 1 can be changed slightly left and right.

[0062] And by Figure 10 It can also be seen that the placement of the photovoltaic junction box at the loading station is perpendicular to the conveying path of the No. 1 linear reciprocating motion mechanism.

[0063] The second handling group 11 is designed to be horizontally movable to cooperate with the turning over of the box body 100a. As described above, "If the box body of the photovoltaic junction box is not turned over by 180° at the adjustment station, the box body is held and fixed by the pressing component on the right. Conversely, if the box body is turned over by 180° at the adjustment station, the box body is held and fixed by the pressing component on the left." If the box body 100a is turned over, it is necessary to move the box body 100a under the pressing component 51 on the left. Since the movement stroke of the first linear reciprocating motion mechanism 1 is fixed each time, only the stroke fine-tuning cylinder 12 can be used to appropriately adjust the position of the second handling group 11 so that it can accurately move the turned-over photovoltaic junction box to the pressing component 51 on the left.

[0064] Similarly, the holding module 57 is designed to be horizontally movable to cooperate with the bending direction of the cable 100b and to better dock with the subsequent installation station 6. Different bending directions result in different loop positions of the finally formed U-shaped cable. By appropriately adjusting the position of the holding module 57 through the stroke fine-tuning cylinder 12, the two holding arms 572 of the holding module 57 can always approach the cable from the outside of the cable 100b inward and can accurately transport the shaped photovoltaic junction box to the installation station 6.

[0065] Combined Figure 11 As shown. The design of the handling group 11 on the first linear reciprocating motion mechanism 1 and the second linear reciprocating motion mechanism 2 mainly includes a handling jaw cylinder 111, a first side portion 112 and a second side portion 113 that can be driven by the handling jaw cylinder 111 to close or separate. Semi-grooves 114 are provided in the middle of the first side portion 112 and the second side portion 113 respectively. When the two semi-grooves are closed, they can form a clamping hole for accommodating the cable. Lapping ends 1121 and mating ends 1131 that can be fitted are provided at the head ends of the first side portion 112 and the second side portion 113 respectively to form a locking effect. The handling jaw cylinder 111 drives the first side portion 112 and the second side portion 113 to close, so as to achieve the clamping effect on the cable 100b, and further achieve a stable handling effect.

[0066] This solution designs multiple functional stations and, by virtue of the mutual cooperation between the stations, can achieve the purpose of bending and buckling and shaping the cables on the photovoltaic junction box, complete the orderly packaging work, adapt to the production requirements of photovoltaic junction boxes with different cable lengths through the important intermediate adjustment station, and can also perform action instructions such as box body turning over, bending direction adjustment, and buckling direction adjustment on the photovoltaic junction box according to the corresponding user requirements, truly realizing multi-functional use of one machine, without complex action design, and having a wide range of applications.

[0067] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
