Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic production, and more specifically, relates to an integrated photovoltaic module manufacturing machine. Background Art

[0002] In the production of photovoltaic silicon cells, several relatively small unit cells are first arranged into cell strings, and then several cell strings are arranged in columns to form rectangular sheets, thereby producing larger solar panels.

[0003] Existing photovoltaic layout welding equipment is usually of reciprocating type. First, all the battery strings to be welded are layouted and then sent to the next process for unified welding. For some small-scale enterprises, the number of their welding production lines is small, and they cannot immediately complete the layout of the battery string group, resulting in a mismatch between the layout and welding process rhythms. The battery string group layout by the layout equipment must wait for the previous group of battery string groups to be welded before welding can be carried out. It is impossible to layout and weld one string at a time. At the same time, the welding of the entire layout of battery strings requires the welding of the entire bus bar, which not only has low production efficiency, but also causes a waste of production resources. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an all-in-one typesetting machine for photovoltaic module manufacturing, which can match the rhythm of typesetting and welding processes and reduce the idle state of typesetting equipment, which can not only improve the production efficiency of typesetting, but also reduce the waste of production resources.

[0048] Specific embodiment 1: Please refer to Figure 1-Figure 17 A busbar integrated machine for manufacturing photovoltaic modules includes a layout assembly, a welding assembly and a busbar handling and forming assembly arranged in sequence. A single battery string is composed of a plurality of battery cells arranged in an array.

[0049] The typesetting assembly includes a conveying assembly 1, an extraction assembly 2 and a transfer assembly 3. The conveying assembly 1 is fixedly arranged on one side of the frame to receive the longitudinally arranged battery strings. The terminal of the conveying assembly 1 is located at the lower side of the extraction assembly 2. The extraction assembly 2 is slidably arranged between the conveying assembly 1 and the transfer assembly 3 to clamp and transfer the battery string. The transfer assembly 3 has a receiving station for receiving the battery string. The battery strings are all placed on the corresponding receiving stations. The transfer assembly 3 is connected to the stepping motor of the peripheral device to move the receiving space to the receiving position by stepping.

[0050] The conveying assembly 1 includes a conveying belt 11 and a conveying motor 12. The conveying belt 11 is fixedly arranged on a frame. The output end of the conveying motor 12 is connected to the conveying belt 11, and the battery string 4 is arranged on the upper side of the conveying belt 11. The conveying belt 11 is used to convey the battery string 4.

[0051] The extraction component 2 includes a suction cup cross bar 21 and an extraction rod 23. The lower end of the extraction rod 23 is connected to the upper side of the suction cup cross bar 21, and the extraction rod 23 is connected to the output end of the external driving mechanism so that the extraction rod 23 can move and rotate. A plurality of suction cups 22 are fixedly arranged on the lower side of the suction cup cross bar 21. The suction cup 22 is controlled by an external air pump to suck and release the battery string 4. The suction cup cross bar 21 includes at least an extraction state and a release state. The suction cup cross bar 21 is located on the upper side of the conveying component 1 and is parallel to the conveying component 1; when the suction cup cross bar 21 is in the release state, the suction cup cross bar 21 is located on the upper side of the receiving station and is parallel to the receiving station.

[0052] It should be noted that, in this embodiment, the external driving mechanism includes a rotating motor and a truss to drive the extraction rod 23 to move and rotate. This is an existing conventional technical means, and its specific connection method and working principle will not be repeated here.

[0053] The transfer assembly 3 comprises a plurality of spaced material plates 31, a translation motor 32 and a transfer plate 33. The material plates 31 are arranged longitudinally and parallel to each other. The upper side of the material plate 31 is a receiving station.

[0054] The material plates 31 are all fixedly arranged on the upper side of the transfer plate 33. The translation motor 32 is fixedly arranged on the frame, and the output end of the translation motor 32 is connected to the transfer plate 33 to drive the material plates 31 to move in a stepping manner. The material plates 31 receive the battery strings one by one in sequence. The transfer assembly 3 is symmetrically arranged on the frame. The material plates 31 on the left and right sides are aligned so that the battery strings on the left and right sides are located on the same straight line, and the material plates 31 on the left and right sides move forward at the same time.

[0055] In this embodiment, the number of the material plates 31 is 6, and the number of the battery strings 4 located on the transfer assembly 1 in one welding is 6. The translation motor 32 is a stepper motor. The material plates 31 located on the left and right sides are aligned.

[0056] When all the battery strings carried by the material plates 31 are processed, the outermost material plates 31 are returned to the exit of the conveying assembly 1. The length of the material plate 31 is shorter than the length of the battery string 4; the two ends of the battery string 4 extend to the outside of the material plate 31 respectively; a string of battery strings 4 is arranged on the material plate 31; the length of the conveyor belt 11 is greater than the length of the battery string 4. The length of the conveyor belt 11 is greater than the length of the battery string. The conveyor belt 11 and the material plate 31 are perpendicular to each other. In this embodiment, the suction cup 22 sucks the battery string and then rotates 90° so that the battery string is parallel to the material plate 31, and the battery string is placed horizontally on the material plate 31.

[0057] The conveying assembly 1, the extracting assembly 2 and the transferring assembly 3 form a group of working units. The platform includes two groups of working units that are symmetrically arranged on the left and right, and the specific structures and working principles of the two groups of working units are the same, so as to increase the number of battery strings 4 during a single typesetting, so as to improve the typesetting efficiency.

[0058] The typesetting component also includes a correction camera; the correction camera is arranged on the upper side of the extraction component 2; the correction camera is electrically connected to the external correction system; the correction system is connected to the extraction component 2 to drive the extraction component 2 to adjust. The correction camera is used to detect the placement state of the battery string on the extraction component 2. If the current state of the battery string does not match the preset state, the correction system drives the extraction component 2 to adjust the battery string to the preset state.

[0059] By setting up a conveying component, an extraction component and a transfer component, each battery string is extracted and placed on a stepping transfer plate. The stepping stroke of the battery string is greatly shortened relative to the reciprocating stroke of the robot, which can reduce the moving stroke of the battery string transportation, reduce the spacing position error during battery string layout, and improve the accuracy of battery string layout.

[0060] The welding assembly includes a welding head assembly 4 and an ejector assembly 5. The welding head assembly 4 is located at the lower side of the battery string, and the abutting surface between the welding head assembly 4 and the battery string is a rigid plane; the ejector assembly 5 is located at the upper side of the battery string and corresponds to the welding head assembly 4.

[0061] The welding head assembly 4 is arranged at the lower side of the transfer plate 33, and the ejector assembly 5 is arranged at the upper side of the transfer plate 33. The welding head assembly 4 includes a welding head, and the ejector assembly 5 includes an ejector. The welding head assembly 4 is arranged on the movable guide rail 44, and the welding head assembly 4 is slidably connected to the movable guide rail 44. The ejector assembly 5 is connected to the output end of the external drive motor so that the welding head and the ejector move up and down correspondingly.

[0062] The welding heads include a left welding head 41, a middle welding head 42 and a right welding head 43. The ejector pins include a left ejector pin 51, a middle ejector pin 52 and a right ejector pin 53. During welding, the left welding head 41 and the left ejector pin 51 are located at the left edge of the battery string on the left, the middle welding head 42 and the middle ejector pin 52 are located in the middle of the left and right battery strings, and the right welding head 43 and the right ejector pin 53 are located at the right edge of the battery string on the right.

[0063] The middle welding head 42 and the right welding head 43 are initially located at the same side; or the middle welding head 42 and the left welding head 41 are initially located at the same side, so as to facilitate the placement of the busbar. When welding, the middle welding head 42 moves to the middle of the left and right battery strings.

[0064] The welded battery strings include at least two groups of battery strings with the same number on the left and right; the busbar welded on the side of each group of battery strings 4 is connected to at least two adjacent battery strings in the group; the busbar welded between the two groups is connected to at least two corresponding groups of three battery strings.

[0065] like Fig.10 As shown, in this embodiment, the battery strings on the left and right sides are welded once for every two strings, for a total of 3 times; the middle part of the two groups of battery strings is welded once for every three strings, for a total of 2 times. Under the premise of ensuring a certain strength, the busbar material required for welding is reduced. When all the battery strings on the material plate 31 are processed, the material plate 31 located on the outermost side is returned to the initial position.

[0066] This is different from the prior art where the welding head is located on the upper side and the ejector pin is located on the lower side. Since the ejector pin is relatively soft in texture and the welding head is a rigid component, it is harder than the ejector pin. It is more stable to place the bus bar on the welding head for welding. At the same time, the ejector pin is located on the upper side for easy movement, and is not prone to interference with other equipment, thus making full use of the equipment space.

[0067] The welding assembly also includes a busbar forming and handling assembly, which includes a handling assembly 6 , a loading assembly 7 , a cutting assembly 8 and a clamping assembly 9 .

[0068] The feeding assembly 7 includes a feeding tray 71 and guide wheels 72.

A plurality of transport frames 64 are slidably connected to the second translation guide rail 62. A plurality of transport frames 64 are connected by a telescopic rod 66 to change the spacing between the transport frames 64. An air nozzle 65 is fixedly arranged on the lower side of the transport frame 64. The air nozzle 65 is connected to the output end of an external air pump. The transport assembly 6 transports the busbar to the corresponding welding assembly.

[0070] The cutting assembly 8 includes a cutting seat 81, a cutter 82, a cutting plate 83, a pressing cylinder 85 and a support seat 86.

Several groups of limit pins 84 are fixedly arranged on the upper side of the cutting plate 83. Each group of limit pins 84 is symmetrically arranged with a gap in the middle. The busbar passes through the gap of each group of limit pins 84. The pressing cylinder 85 is fixedly arranged in front of the discharge port of the feeding assembly 7. The support seat 86 is correspondingly arranged on the lower side of the pressing cylinder 85. A pressure head is fixedly arranged at the lower end of the pressing cylinder 85. The busbar is located on the lower side of the pressure head so as to be selectively pressed.

The clamping seat 91 is slidably connected to the clamping guide rail. The clamping jaw 92 is fixedly arranged on the clamping seat 91, and the clamping jaw 92 is located on the upper side of the cutting plate 83 for clamping the busbar. The pressing plate 93 is fixedly arranged on one side of the cutting plate 83, and the lower end of the pressing plate is connected to the angle cylinder. In the clamping state, the pressing plate 93 is arranged toward the cutting plate 83 to clamp the busbar. In the relaxed state, the pressing plate 93 is arranged away from the cutting plate 83 to release the busbar.

[0072] In this embodiment, two sets of busbar forming and handling assemblies are provided, and two sets of cutting assemblies 8 are provided on the left and right. The cutting plates 83 of the two sets of cutting assemblies 8 are of different lengths, and the busbars cut by each set are of different lengths.

[0073] In this embodiment, the cut busbars are transferred from the transport assembly 6 to the corresponding welding head assembly 4 .

[0074] Working principle:

[0075] The conveyor belt 11 of the conveying component 1 receives the battery strings 4 arranged longitudinally, and the terminal of the conveyor belt 11 is located at the lower side of the extraction component 2. The extraction component 2 is slidably arranged between the conveying component 1 and the transfer component 3 to clamp and transfer the battery strings 4 to the receiving station of the transfer component 3. The transfer component 3 is connected to the stepping motor of the peripheral device to move the receiving position to the receiving position by stepping. The transfer component 3 includes a plurality of spaced material plates 31, which are arranged longitudinally and parallel to each other. The upper side of the material plates 31 is the receiving station. The material plates 31 move in steps to receive the battery strings 4. The battery strings 4 located at the conveying component 1 are arranged longitudinally, and the battery strings 4 located at the receiving station are arranged transversely. The suction cup cross bar 21 of the extraction component 2 absorbs the battery strings 4, and the extraction rod 23 transfers the suction cup cross bar 21 to the receiving station and releases the battery strings 4, wherein the correction camera adjusts the battery strings 4 with position offset.

[0076] Starting from the first plate 31 of the transfer assembly 8, the battery strings are placed on the plate 31 one by one, the plates 31 on the left and right sides are aligned and moved forward at the same time for welding, the bus bars are placed on the welding heads, and the left welding head 41 and the right welding head 43 on the left and right sides respectively weld every two battery strings on the left and right sides, for a total of 3 times; at the same time, the middle welding head 42 moves toward the middle and welds every three strings in the middle part of the two groups of battery strings, for a total of 2 times; the welding head and the ejector pin move up and down in correspondence to perform welding; after welding is completed, the welded battery panel is taken out, and the transfer assembly 1 returns to its initial position.

[0077] The busbar is wound on the supply tray 71, and the busbar is transported to the cutting assembly 8 by the guide wheel 72; when the busbar is cut, the busbar is clamped between the pressure head and the support seat 86, the busbar passes between the limit pins 84 of the cutting plate 83, and the cutter 82 moves to cut the busbar; when the busbar is pulled, the clamping seat 91 moves to the free end of the busbar, and the free end of the busbar is clamped by the clamping claw 92, and the clamping seat 91 moves to the farthest end to pull and pull the busbar. The cut busbar is transferred through the conveying assembly 6, and each time a section of the busbar is cut, a section of the busbar is conveyed, which can reduce the cutting and forming stroke of the busbar. The busbar can be conveyed immediately after the cutting is completed, and there is no need to wait for the busbar to be completely cut before conveying. With the step-by-step moving battery string, the time taken to wait for the busbar to be cut is reduced, thereby improving the production efficiency of the processing flow.
