Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic module assembly equipment, and particularly relates to an auxiliary mechanism for pasting labels on the back of the bus bar of a photovoltaic module.

Background Art

[0002] At present, there is a photovoltaic module which, according to its process requirements, needs to paste a label on the back of the bus bar at the outer edge of the cell in a corner area of the photovoltaic module. Since the label needs to be pasted on the back of the bus bar, when the photovoltaic module comes in, the bus bar is placed on an EVA film together with the cells, and the EVA film is laid on a glass bottom plate. Therefore, when pasting the label, it is necessary to lift the cell module connected to the bus bar upward before pasting the label.

[0003] In the prior art, the patent publication number CN115557043A discloses a photovoltaic module insulating small material placing and labeling integrated device and a process method, and further discloses a cell module lifting unit. This lifting unit directly lifts the cell module upward, and then is configured with a pressing module to press it after the label is pasted. However, when pasting a label on the back of the bus bar, it is easy to lift the underlying EVA film together when lifting the cell module, causing misalignment of the cell modules in other areas; in addition, when pasting a label on the back of the bus bar, there is no reverse support on the upper surface, resulting in insecure label pasting and easy detachment.

[0004] Therefore, it is necessary to provide a new auxiliary mechanism for pasting labels on the back of the bus bar of a photovoltaic module to solve the above technical problems.

Content of the Utility Model

[0005] The main purpose of the utility model is to provide an auxiliary mechanism for pasting labels on the back of the bus bar of a photovoltaic module, which can effectively prevent the EVA film from being lifted and ensure firm pasting of the label on the back of the bus bar.

[0007] Further, the first support plate is arranged on the support cross beam in a position where it can be adjusted left and right.

[0008] Further, it also includes a pair of slide rails arranged perpendicular to the support cross beam. Sliders are arranged at both ends of the support cross beam, and the sliders are slidably arranged on the slide rails and locked and fixed by locking pieces.

[0009] Further, two mounting positions for mounting the second film pressing module are provided on the first support plate, and the two mounting positions are located on the left and right sides of the lifting module.

[0010] Further, the lifting module includes a first air cylinder fixed on the first support plate, a second support plate driven by the first air cylinder to move back and forth, a second air cylinder fixed on the second support plate, a third support plate driven by the second air cylinder to move up and down, and a first adsorption assembly fixed on the third support plate; the first adsorption assembly includes a plurality of suction nozzles arranged in the left-right direction.

[0011] Further, the first film pressing module is arranged at the front end of the third support plate; the first film pressing module includes a third air cylinder fixed on the third support plate, a fourth support plate driven by the third air cylinder to move up and down, and a second adsorption assembly arranged on the fourth support plate; the second adsorption assembly includes a plurality of suction nozzles arranged in the left-right direction.

[0013] Compared with the prior art, the beneficial effects of the auxiliary mechanism for back labeling of the bus bar of a photovoltaic module of the present utility model are as follows: by setting the second film pressing module for pressing the EVA film, the EVA film is pressed before the battery cell module is lifted, effectively preventing the EVA film from being lifted; at the same time, by setting the first film pressing module for pressing the upper surface of the bus bar, the bus bar is adsorbed and fixed after the bus bar is lifted. On the one hand, the position of the bus bar is ensured to be accurate, and on the other hand, a reverse supporting force is provided during the label pasting process, ensuring that the label is firmly pasted and improving the label pasting quality; by setting the adjustment structures in the front-back, left-right directions, it is convenient for the auxiliary mechanism to adjust the position, improving the versatility of the equipment.

Detailed implementation manner

[0019] Embodiment 1:

[0020] Please refer to Figure 1 - Figure 2 , this embodiment is an auxiliary mechanism 100 for attaching labels to the back of the busbar of a photovoltaic module, which includes a support crossbeam 1, a first support plate 2 arranged on the support crossbeam 1, a lifting module 3 fixed on the first support plate 2 and used to lift the battery cell, a first film pressing module 4 for pressing the upper surface of the busbar at the edge of the battery cell, and a second film pressing module 5 for pressing the thin film below the battery cell.

[0021] In order to improve the versatility of the auxiliary mechanism and facilitate the position adjustment of each module, the first support plate 2 is arranged on the support crossbeam 1 with adjustable left and right positions. In addition, this embodiment also includes a pair of slide rails 6 arranged perpendicular to the support crossbeam 1. Sliders 7 are arranged at both ends of the support crossbeam 1. The sliders 7 are slidably arranged on the slide rails 6 and are locked and fixed by locking pieces 8, realizing the adjustable position of the support crossbeam 1 in the front and back directions.

[0022] For photovoltaic modules, according to different customer requirements, some need to attach labels to the back of the busbar on the outer edge of the battery cells in the front area on one side of the photovoltaic module, while some need to attach labels to the back of the busbar on the outer edge of the battery cells in the rear area on one side of the photovoltaic module. In order to adapt to these two situations, two installation positions 21 for installing the second film pressing module 5 are arranged on the first support plate 2. The two installation positions 21 are located on the left and right sides of the lifting module 3, so that the second film pressing module 5 can press and fix the EVA film at the outer edge of the photovoltaic module.

[0023] The lifting module 3 includes a first cylinder 31 fixed on the first support plate 2, a second support plate 32 driven by the first cylinder 31 to move back and forth, a second cylinder 33 fixed on the second support plate 32, a third support plate 34 driven by the second cylinder 33 to move up and down, and a first adsorption component 35 fixed on the third support plate 34. The first adsorption component 35 includes a plurality of suction nozzles arranged in the left - right direction.

[0024] The first film pressing module 4 is arranged at the front end of the third support plate 34, and the second support plate 32 is driven to move forward and backward by the first cylinder 31, driving the first film pressing module 4 to move forward and backward together, so that the first film pressing module 4 can switch between the working position and the avoidance position, and avoid the space above the edge bus bar at the avoidance position, so as to facilitate the visual positioning camera to obtain the position information of the bus bar and improve the labeling accuracy.

[0025] The first laminating module 4 includes a third cylinder 41 fixed on the third support plate 34, a fourth support plate 42 driven by the third cylinder 41 to move up and down, and a second adsorption assembly 43 arranged on the fourth support plate 42. The second adsorption assembly 43 includes a plurality of suction nozzles arranged in a left-right direction. The first laminating module 4 is used to provide a downward supporting force to the upper surface of the busbar when the label is pasted on the back of the busbar, so as to ensure that the label can be reliably and effectively attached to the back of the busbar.

[0026] The second film pressing module 5 includes a fourth cylinder 51 fixed on the first support plate 2, a fifth support plate 52 driven by the fourth cylinder 51 to move up and down, and a third adsorption assembly 53 arranged on the fifth support plate 52. The third adsorption assembly 53 includes a plurality of suction nozzles arranged in a front-to-back direction. The second film pressing module 5 is used to press the EVA film under the battery cell before the lifting module 3 lifts the battery cell, so as to prevent the EVA film from being lifted when the battery cell is lifted, causing the battery cell module in other areas to move out of position or the EVA film to be partially wrinkled.

[0027] When installing the auxiliary mechanism of this embodiment, first determine the position where the label is pasted, and then determine whether the second film pressing module 5 is set on the left or right side of the lifting module 3, and at the same time, determine whether the position of the first support plate 2 is close to the left or right side of the supporting beam 1; after determining the positions of the second film pressing module 5 and the first support plate 2, adjust the front and rear directions of the supporting beam 1 to ensure that the first film pressing module 4 can accurately align with the bus bar; when labeling, first the second film pressing module 5 is lowered to press the EVA film, and then the lifting module 3 is lowered to absorb the battery cell module, and then it is lifted up; the first film pressing module 4 is actuated to absorb and press the upper surface of the bus bar lifted up together with the battery cell module, and then labeling is performed. After the label is pasted, the first film pressing module 4 is released, the lifting module 3 puts down the battery cell module, and the second film pressing module 5 is lifted up to complete a cycle of action.

[0028] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
