[0002] After the solar cell modules are installed, Busbars connect solar cells on solar panels , the solar cell produces Electric energy is centrally transmitted through the junction box To the load or energy storage device in the solar power generation system.

[0003] For solar cell modules Busbar It is usually stored by rolling up, so Busbars and cells Before welding, the busbar needs to go through unwinding, cutting, bending and crimping in sequence. Therefore, in order to ensure that the current can be transmitted smoothly and safely, the ends of the busbar are generally designed to be foldable to facilitate installation and connection, enhance stability, prevent short circuits, and adapt to different wiring requirements.

[0004] However, in order to adapt to different wiring requirements, the folding forms of the busbar ends are not completely consistent. The simplest is a single vertical folding, while the more complex ones need to be folded at a 45-degree angle first and then pressed into a horizontal shape. For this kind of multi-form folding of the busbar ends, different folding devices are generally required, resulting in an increase in production costs. Summary of the invention

The clamping assembly includes a lower pressure block that can be raised and lowered on the rear side of the machine base panel and an upper pressure block that is driven to rise and fall by a cylinder. When cutting the busbar, the upper pressure block cooperates with the lower pressure block to press the busbar.

A slide cylinder and a guide rod cylinder are installed on the machine base panel on the inner side of the busbar. The slide cylinder pushes the guide rod cylinder to move perpendicular to the direction of the busbar, and the pad is fixedly connected to the piston rod of the guide rod cylinder.

[0012] Furthermore, in order to ensure that the busbar is more flat when folded, the side of the pad opposite to the eccentric pressure rod has a slope surface, and the eccentric pressure rod rotates to fold the end of the busbar horizontally onto the slope surface.

A push-pull cylinder is installed at the lower part of the hanger, and a support is fixedly connected to the push-pull cylinder piston rod. The clamping seat is located below the support, and a rocker arm is provided between the clamping seat and the support. The upper end of the rocker arm is hinged to the support, and the lower end of the rocker arm is hinged to the clamping seat. The clamping block is fixed to the lower end of the rocker arm and rotates to cooperate with the clamping seat to clamp the end of the bus bar after the push-pull cylinder piston rod is extended.

DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] like Figure 1The illustrated embodiment is an integrated folding device for the multi-form ends of a busbar of a stitch welding machine, which has a base panel 1, and the base panel 1 can be installed on the frame of a stitch welding machine production line. A folding area is provided on the base panel 1, and the folding area includes first folding mechanisms 2 respectively arranged at both ends of the base panel 1, a second folding mechanism 3 is provided on the base panel 1 located between the first folding mechanisms 2, and folding tables are respectively provided on the base panel 1 corresponding to the first folding mechanism 2 and the second folding mechanism 3; a cutting mechanism 4 is provided on the base panel 1 located at the front end of the folding area, a traction mechanism 5 that can move across the base panel 1 is provided above the folding area, a guide mechanism 6 is provided on the base panel 1 at the front end of the cutting mechanism 4, and a clamping assembly 7 is provided between the guide mechanism 6 and the cutting mechanism 4.

[0028] The above-mentioned first folding mechanism 2 is used to complete the vertical folding of the end of the busbar 9 upwards, and the second folding mechanism 3 is used to complete the lateral horizontal folding of the end of the busbar 9; the cutting mechanism 4 is used to cut the transmitted busbar 9 according to the length specification, and the traction mechanism 5 pulls the busbar 9 cut by the cutting mechanism 4 to the position area of ​​the first folding mechanism 2 or the second folding mechanism 3 for folding and forming.

[0029] like Figure 4 As shown, the cutting mechanism 4 includes a bracket 4-4 fixed on the base panel 1, the bracket 4-4 has a vertical plate, the center of the vertical plate is provided with a rectangular opening for passing the bus bar 9, the bottom of the vertical plate is fixedly connected to a bottom plate fixed to the base panel 1, a pair of linear guides are installed on the front of the vertical plate facing the folding area, an upper cylinder 4-5 is installed on the upper end of the vertical plate of the bracket 4-4, and a lower cylinder 4-6 is installed on the base panel 1 on the rear side of the lower end of the vertical plate, and the upper ends of the pair of linear guides are fixed between An upper connecting plate is connected, and a lower connecting plate is fixedly connected between the lower ends. An upper cutter 4-1 is installed at the bottom middle end of the upper connecting plate, and a lower cutter 4-2 is installed at the upper middle end of the lower connecting plate. The piston rod of the upper cylinder 4-5 is fixedly connected to the upper end of the upper connecting plate, and the piston rod of the lower cylinder 4-6 is fixedly connected to the upper end of the lower connecting plate through a T-shaped plate. Under the action of the upper cylinder 4-5 and the lower cylinder 4-6, the upper cutter 4-1 and the lower cutter 4-2 cooperate to cut off the bus bar 9 when they move close to each other, and the upper cutter 4-1 and the lower cutter 4-2 are reset separately when they move far away from each other.

[0030] A lifting plate 4-3 is provided near the rear side of the lower cutter 4-2, and a lifting cylinder 4-7 for driving the lifting plate 4-3 to move up and down is installed on the base panel 1 located at the center bottom of the bracket 4-4. After the upper cutter 4-1 and the lower cutter 4-2 cooperate to cut the bus bar 9, the lifting plate 4-3 rises to lift the end of the bus bar 9 to a suspended state, so that the traction mechanism 5 can clamp the end of the bus bar 9.

[0031] Since the busbar 9 is relatively thin, if the lifting plate 4-3 is too far away from the end of the busbar 9, the end of the busbar 9 is likely to sag due to the flexibility, thereby affecting the traction mechanism 5 from grasping the busbar 9; if the lifting plate 4-3 is too close to the lower cutter 4-2, it is easy to cause friction between the lower cutter 4-2 in the case of processing and assembly errors. Based on this, it is preferred that the spacing between the lifting plate 4-3 and the lower cutter 4-2 is 3mm.

[0032] See also Figure 5 As shown, the traction mechanism 5 includes a sliding seat 5-3, a hanger 5-4, a clamping seat 5-1 and a clamping block 5-2. A synchronous belt linear module 8 is installed across the machine base panel 1. The sliding seat 5-3 is slidably installed on the synchronous belt linear module 8. When the synchronous belt linear module 8 drives the sliding seat 5-3 to move across the machine base panel 1, the traction mechanism 5 pulls the cut bus bar 9 to the folding area.

[0033] The hanger 5-4 can be lifted and installed on the sliding seat 5-3, and an adapter plate 5-9 is fixedly connected to the end surface of the hanger 5-4. A push-pull cylinder 5-5 is provided at the lower part of the hanger 5-4. A rear end plate 5-10 is fixed to the rear end of the push-pull cylinder 5-5. The rear end plate 5-10 is fixed to the bottom end surface of the adapter plate 5-9. A front end plate 5-11 is fixed to the front end of the push-pull cylinder 5-5. The piston rod of the push-pull cylinder 5-5 passes through the front end plate 5-11 and is fixedly connected to the support 5-6. The clamp seat 5-1 It is fixed on the bottom surface of the front end plate 5-11 and is located below the support 5-6. A rocker arm 5-7 is provided between the clamp seat 5-1 and the support 5-6. The upper end of the rocker arm 5-7 is hinged to the support 5-6, and the lower end of the rocker arm 5-7 is hinged to the clamp seat 5-1. The clamp block 5-2 is fixed at the lower end position of the rocker arm 5-7. After the piston rod of the push-pull cylinder 5-5 is extended, the rocker arm 5-7 is driven to rotate and the clamp block 5-2 is driven to rotate to cooperate with the clamp seat 5-1 to clamp the end of the suspended bus bar 9.

[0034] The front end face of the sliding seat 5-3 and the hanger 5-4 are slidably matched through the sliding rail slider, and the rear end face of the sliding seat 5-3 is installed with an adjusting cylinder 5-8 for driving the hanger 5-4 to rise and fall. In this way, the height of the clamping block 5-2 and the clamping seat 5-1 can be easily adjusted, so that the clamping position formed by the clamping block 5-2 and the clamping seat 5-1 is consistent with the height of the bus bar 9, so as to ensure that the bus bar 9 is smoothly pulled to the folding area.

[0035] Since both ends of the busbar 9 need to be folded vertically, a first folding mechanism 2 is provided at both ends of the folding platform where the busbar 9 to be folded is located. Figure 2As shown, the first folding mechanism 2 has a pressing block 2-1 and a folding roller 2-2, a lifting cylinder 2-3 is installed on the machine base panel 1 located outside the busbar 9, and an axle seat 2-4 is fixedly connected to the piston rod of the lifting cylinder 2-3 through a connecting plate, and the folding roller 2-2 is rotatably installed on the axle seat 2-4, and a first rotary clamping cylinder 2-5 is installed on the machine base panel 1 located inside the busbar 9, and the pressing block 2-1 is fixedly connected to the piston rod of the first rotary clamping cylinder 2-5. During folding, the first rotary clamping cylinder 2-5 drives the pressing block 2-1 to rotate to the top of the busbar 9 and then descends to press against the end surface of the busbar 9, and then when the lifting cylinder 2-3 pushes the axle seat 2-4 to rise, the folding roller 2-2 located below the end of the busbar 9 to be folded rolls and presses against the bottom surface of the end of the busbar 9, and as the axle seat 2-4 rises, the folding roller 2-2 cooperates with the pressing block 2-1 to fold the end of the busbar 9 vertically upward.

[0036] Similarly, a second folding mechanism 3 is provided at both ends of the folding platform where the busbar 9 to be folded is located, so as to complete the horizontal folding of both ends of the busbar 9. Figure 3 As shown, the second folding mechanism 3 includes an eccentric pressure rod 3 - 1 , a pad 3 - 2 and a right-angle pressure block 3 - 3 , wherein the axis of the eccentric pressure rod 3 - 1 forms an angle of 45 degrees with the moving direction of the busbar 9 .

[0037] A rotating cylinder 3-4 and a second rotating clamping cylinder 3-5 are respectively installed on the base panel 1 on the outside of the bus bar 9. The power output end of the rotating cylinder 3-4 is transmission-connected with the eccentric pressure rod 3-1. The eccentric pressure rod 3-1 is eccentric with respect to the rotation center of the rotating cylinder 3-4. The right-angle pressure block 3-3 is fixedly connected to the piston rod of the second rotating clamping cylinder 3-5. A sliding cylinder 3-6 and a guide rod cylinder 3-7 are installed on the base panel 9 located on the inside of the bus bar 9. The sliding cylinder 3-6 pushes the guide rod cylinder 3-7 to move perpendicular to the direction of the bus bar 9. The pad 3-2 is fixedly connected to the piston rod of the guide rod cylinder 3-7.

[0038] When folding, the pad 3-2 moves toward the side of the busbar 9 under the action of the slide cylinder 3-6 and is lifted and lowered on the folding table under the action of the guide rod cylinder 3-7. The pad 3-2 has a sloped surface on the side opposite to the eccentric pressure rod 3-1. The rotary cylinder 3-4 drives the eccentric pressure rod 3-1 to rotate and fold the end of the busbar 9 horizontally on the sloped surface of the pad 3-2 to ensure that the busbar 9 is flatter when folded; then, under the action of the slide cylinder 3-6, the pad 3-2 is moved out from the bottom surface of the folded busbar 9, and the guide rod cylinder 3-7 drives the pad 3-2 to rise and reset. At the same time, the second rotary clamping cylinder 3-5 is actuated to drive the right-angle pressure block 3-3 to rotate above the end of the busbar 9 and press down on the folded busbar 9 to press the folded end of the busbar 9 tightly and flatten it.

[0039] In order to ensure that the bus bar 9 can smoothly enter the cutting mechanism 4, a guide mechanism 6 is also provided on the base panel 1 at the front end of the cutting mechanism 4. Figure 6 As shown, the guide mechanism 6 has a guide frame 6-1 fixed on the base panel 1, and a horizontal guide wheel group 6-2 and a vertical guide wheel group 6-3 are sequentially installed on the guide frame 6-1 along the moving direction of the bus bar 9. The guide wheels of the horizontal guide wheel group 6-2 are in contact with the two side surfaces of the bus bar 9 for guidance, and the guide wheels of the vertical guide wheel group 6-3 are in contact with the upper and lower surfaces of the bus bar 9 for guidance. The bus bar 9 passes through the guide mechanism 6 and enters between the upper cutter 4-1 and the lower cutter 4-2.

[0040] Furthermore, when the busbar 9 is only subjected to the pressure of the upper cutter 4-1 and the lower cutter 4-2 but has not been cut, it is easy to bend and deform, thereby affecting the cutting accuracy and stability of the busbar 9. Therefore, a clamping assembly 7 is installed on the machine base panel 1 on the front side of the discharge end of the vertical guide wheel group 6-3 and the rear side of the lifting plate 4-3. The clamping assembly 7 includes a lower pressing block 7-1 arranged on the T-shaped plate and pushed up and down by the lower cylinder 4-6, and an upper pressing block 7-2 driven to be lifted and down by the cylinder. In this way, when the upper cutter 4-1 and the lower cutter 4-2 cut the busbar 9, the upper pressing block 7-2 and the lower pressing block 7-1 press the busbar 9 to prevent the busbar 9 from bending and deforming and causing cutting length deviation.

[0041] The above-mentioned integrated folding device can be equipped with a separate first folding mechanism 2 or a second folding mechanism 3 according to the process requirements, or different numbers of first folding mechanisms 2 or second folding mechanisms 3 can be arranged in combination. After the cutting mechanism 4 cuts the bus bar 9 according to the length requirement, the traction mechanism 5 clamps the cut ends of the bus bar 9 and pulls them into the folding area. The first folding mechanism 2 completes the upward vertical folding of the two ends of the bus bar 9, or the second folding mechanism 3 completes the horizontal folding of the two ends of the bus bar 9. In this way, the multi-form folding processing of the ends of the bus bar 9 can be completed, thereby reducing the equipment usage and reducing the production cost.

[0042] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
