Description

Technical Field

[0001] The invention relates to the field of photovoltaic component production equipment, and in particular to a high-speed photovoltaic component splitting mechanism. Background Art

[0002] As an important component of solar power generation, the manufacturing technology of photovoltaic modules has not changed significantly for a long time. In particular, the string welding machines used to produce conventional string welding modules have always had defects such as low equipment production capacity and poor process stability. In particular, the recent emergence of half-cell and multi-busbar technologies has not only reduced the production capacity of photovoltaic module production equipment, but also put forward higher requirements on the process stability of the equipment. These defects have been hindering the large-scale promotion and application of photovoltaic modules.

[0003] In recent years, a shingled component technology has emerged on the market, which divides the entire large cell into several small cells, and then connects the positive and negative electrodes of the small cells into strings through conductive materials. However, this technology still has the following major problems when splitting the cells. After splitting the large cell into several small pieces, the production capacity of the equipment needs to be increased several times, and during the splitting process, the small cells will also have defects such as hidden cracks and edge collapse. This greatly affects the efficiency and quality of the split. Summary of the invention

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , the embodiment of the present invention includes:

[0025] A high-speed photovoltaic module splitting mechanism is used to split a large cell into several small cells and adjust the spacing to a desired spacing, simplifying the mechanism and improving the reliability and splitting efficiency of the device. When the cell is split into small cells, edge small cells and middle small cells are formed. The splitting mechanism can be arranged in one or more groups to achieve splitting of one cell or multiple cells at the same time.

[0026] The cell splitting mechanism includes a frame body 201 , a rotating plate 202 , a rotating mechanism, a moving mechanism, a cam guide plate 203 , a vacuum adsorption hole 204 , and a waste collection box 205 .

[0027] One rotating plate corresponds to a small battery cell. A vacuum adsorption hole is provided on the rotating plate. A vacuum valve 206 and a vacuum pressure switch 207 are connected to the vacuum adsorption hole. A vacuum diversion plate 208 for fixing the diversion air pipe is provided on the frame body. When the battery cell feeding mechanism transports the large battery cell to the splitting mechanism, the vacuum adsorption hole adsorbs and fixes the large battery plate on the rotating plate, which is convenient for subsequent splitting and movement.

[0028] The rotating plate can also be affixed with a wear-resistant Teflon film. When the film is worn to a certain extent, it can be torn off and replaced with a new one to minimize the probability of cracks, edge collapse, degranulation and other splinter defects.

[0029] The rotating mechanism is used to drive the rotating plate to rotate, so that the rotating plate bends the large battery cell until the small battery cell is split out. The rotating mechanism can be set on one side of the rotating plate or on both sides of the rotating plate, which can apply force to the rotating plate more evenly and improve the splitting efficiency and quality.

[0030] The rotating mechanism includes a rotating cam plate 209, a rotating rod 210, and an eccentric adjustment ring 211. The rotating cam plate is arranged on the cam guide plate. The rotating cam plate is provided with a rotating curve guide groove 212. One rotating curve guide groove corresponds to one rotating rod. The upper end of the rotating rod is fixedly connected to the rotating plate, and the lower end of the rotating rod is connected to an eccentric adjustment ring and a cam follower. One end of the cam follower moves back and forth in the rotating curve guide groove, and the other end is movably arranged in the eccentric adjustment ring. During the movement, the eccentric adjustment ring can fine-tune the position angle of the cam follower to drive the rotating rod to move more smoothly and prevent the cam follower and the rotating rod from getting stuck.

[0031] The rotating curve guide groove contains at least two rotation intervals for changing the state of the rotating plate. When there are two rotation intervals, the rotating cam plate moves upward so that the cam follower encounters and enters the first rotation interval on the rotating curve guide groove, and the eccentric adjustment ring and the cam follower cooperate to drive the rotating plate to rotate through the rotating rod, thereby splitting the large battery cell into multiple small battery cells. When the rotating cam plate continues to move upward so that the cam follower encounters and enters the second rotation interval on the rotating curve guide groove, the eccentric adjustment ring and the cam follower cooperate to drive the rotating plate to rotate in the opposite direction through the rotating rod, thereby adjusting the rotating plate to a horizontal state.

[0032] The moving mechanism is used to drive the rotating plate to move forward and backward on the frame body, so as to adjust the distance between each rotating plate. The moving mechanism can be arranged on both sides of the rotating plate, and can synchronously drive the rotating plate to move horizontally.

[0033] The moving mechanism includes a moving cam plate 213, a moving rod 214, a cam follower 215, a guide wheel 216, a guide rail 217, and a connecting frame 218. The guide rail is arranged on the frame body, and the moving rod drives the connecting frame to move back and forth along the guide rail. The moving cam plate is arranged on the cam guide plate, and a moving curve guide groove 219 is arranged on the moving cam plate. One moving curve guide groove corresponds to one moving rod. The upper end of the moving rod is movably connected to the rotating plate through the cam follower, and the lower end of the moving rod is connected to a guide wheel that moves back and forth in the moving curve guide groove.

[0034] The moving curve guide groove contains at least two moving intervals for changing the position of the rotating plate. When there are two moving intervals, the moving cam plate moves upward to make the guide wheel encounter and enter the first moving interval on the moving curve guide groove, and the moving rod drives the rotating plate to move in a translational manner through the cam follower, so that the two adjacent rotating plates are separated to facilitate the splitting. When the moving cam plate continues to move upward to make the guide wheel encounter and enter the second moving interval on the moving curve guide groove, the moving rod adjusts the spacing between the rotating plates.

[0035] Each rotating plate is connected with a moving rod and a rotating rod. A rotating plate in the middle may not be connected with the moving rod and the rotating rod. In this case, the middle rotating plate may be arranged on the frame body through a fixing rod.

[0036] When processing battery cells with an odd structure, a corresponding odd number of rotating plates are required to form a group for splitting, and the rotating rod and the moving rod may not be connected to the rotating plate in the middle position, for example: when a 5-piece structure is adopted, the third rotating plate is the middle rotating plate; when processing battery cells with an even structure, a corresponding even number of rotating plates are required to form a group for splitting, and the rotating rod and the moving rod may not be connected to any one of the two rotating plates in the middle position, for example: when a 6-piece structure is adopted, any one of the third or fourth rotating plates can be used as the middle rotating plate.

[0037] The user may need to adjust the shape and direction of the rotating curved guide groove and the moving curved guide groove according to the structural dimensions of the product and the production capacity, processing accuracy, processing quality and other information of the equipment, and the rotating curved guide groove and the moving curved guide groove need to cooperate with each other.

[0038] If the shapes of the rotating / moving curved guide grooves are the same: a. the direction and height (i.e. the distance between the guide groove and the bottom surface of the cam plate) are also the same, then the rotating / moving cam plate can simultaneously drive all rotating plates to rotate / move in the same direction when it moves upward; b. when the directions are the same but the heights are different, the rotating / moving cam plate can sequentially drive the corresponding rotating / moving plates to rotate / move in the same direction in order from high to low; c. when the directions are different but the heights are the same, then the rotating / moving cam plate can simultaneously drive all rotating plates to rotate / move in the same or different directions when it moves upward, wherein a fixed middle rotating plate can be used as an intermediate axis, and the rotating / moving curved guide grooves on both sides of the intermediate axis are set in opposite directions.

[0039] If the shapes of the rotation / movement curve guide grooves are the same but the directions and heights are different or the shapes of the rotation / movement curve guide grooves are different, the rotation / movement activation order is determined according to the order in which the rotating rod or the moving rod encounters and enters the intervals, and then the rotation / translation operation of each rotating plate is controlled according to the corresponding curve guide groove shape and direction.

[0040] The waste collection box is movably arranged in the frame body and is located below the guide rail, and can collect debris and waste that may be generated during the splitting process.

[0041] The height of the rotating rod in the split device is guaranteed by the processing accuracy; the flatness of the multiple rotating plates can be precisely adjusted by the eccentric adjustment ring, and the lever structure of the rotating plate can greatly reduce the error caused by the cam groove processing, and the adjustment method is fast and convenient.

[0042] The split lifting drive device drives the cam guide plate to move up and down on the frame body, so that the cam guide plate can simultaneously drive the rotating cam plate and the movable cam plate to move up and down. The split lifting drive device can adopt a servo electric cylinder 220. The servo motor drives the electric cylinder to adjust the lifting speed of the electric cylinder according to the cam contour curve, and drives the cam curve. When encountering a turning point on the curve, the speed of the electric cylinder decreases, achieving a softer movement than the cylinder, causing less damage to the battery cell, and reducing splinter defects such as hidden cracks.

[0043] The cam guide plate, rotating cam plate and movable cam plate can be arranged on the outside of the frame body. When changing the specifications of the battery cells to be processed, fast and low-cost switching can be performed to meet the production needs of battery cells of different sizes. For example, when switching from battery cells with specifications of 1 / 5, 156.25 to battery cells with specifications of 1 / 5, 157.25, it is only necessary to replace the cam plate corresponding to the size of 156.25 with the cam plate corresponding to 157.25. In this way, the device can be converted to produce battery cells of size 157.25 to meet the production needs of battery cells of various specifications on the current market. Specific embodiment 1

[0045] The large battery cell that needs to be processed by the battery cell splitting mechanism contains 6 small battery cells. The moving rods are arranged on both sides of the rotating plate, the rotating rods are arranged on one side of the rotating plate, and the third rotating plate is the intermediate axis. The bottom of the connecting frame moves back and forth on the 3 guide rails, and the two sides of the connecting frame are connected to the moving rods.

[0046] The shapes and directions of the rotating curved guide grooves on the rotating cam plate are different, and the shapes and directions of the moving curved guide grooves on the moving cam plate are also different. The first section of the curved guide grooves on both sides of the shaft is close to the intermediate shaft, and the second section is far away from the intermediate shaft.

[0047] When the feeding mechanism places multiple battery cells on the splitting mechanism, the adsorption holes adsorb the battery cells onto the rotating plate; the servo electric cylinder drives the cam plate to move upward through the cam guide plate; the middle rotating plate remains stationary, and the outer rotating rod first encounters and enters the first rotating section of the rotating curve guide groove (at this time, the middle rotating rod and all moving rods have not entered the section), so that the outer rotating plates rotate in sequence to split; the cam plate continues to move upward, and the rotating rod continues to drive the rotating plate to rotate in sequence from the outside to the inside, and at the same time, the moving rod also enters the first moving section on the moving curve guide groove in sequence from the outside to the inside, driving the rotating plates that are rotating or have been rotated to translate one by one and move away from the middle axis, completing the splitting and separation of all small battery cells; the cam plate continues to move upward, and the rotating rod and the second rotating section are used to adjust the split rotating plates to a horizontal state at the same time, and the rotating plates are adjusted to the required spacing through the moving rod and the second moving section, without the need for subsequent mechanisms to perform spacing operations, thereby reducing the number of actions and improving production capacity.

[0048] The beneficial effect of the high-speed photovoltaic module splitting mechanism of the present invention is that a more precise splitting operation is achieved by using a rotating mechanism and a moving mechanism, which can effectively improve the production capacity and reduce the probability of producing defective products.

[0049] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
