Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic production equipment, in particular to a carrying mechanism and a cell piece film stacking device. BACKGROUND

[0002] In order to avoid the local stress caused by the welding strip to the edge of the cell piece when the cell string assembly is laminated, which leads to the hidden cracking of the cell piece, a film strip can be arranged between the adjacent two cell pieces during the production of the cell string, and the stress of the cell piece caused by the welding strip can be buffered through the film strip.

[0003] In the traditional cell string forming process with a film strip, the cell pieces and the welding strip are first connected into a string, and then the film strip is inserted into the position between the cell pieces of the cell string. Since the cell pieces and the welding strip have been connected, one of the adjacent two cell pieces needs to be lifted to form an insertion gap when the film strip is inserted. The existing cell string forming process with a film strip is not only troublesome to operate, but also easy to cause damage to the cell pieces.

[0004] In order to improve the stringing efficiency and quality, a feasible solution is to first carry and stack the film strip on the carrying table onto the cell piece on the first conveying line (cell piece loading conveying line) through the film strip carrying mechanism to obtain a cell unit. Then, the cell unit is carried from the first conveying line to the second conveying line by the cell carrying mechanism, and the cell unit is conveyed to the subsequent stringing station by the second conveying line. Finally, the cell unit and the welding strip group are laid according to the stringing rule by the cell piece stringing device, and the film strip automatically enters between the adjacent cell pieces during the stringing process.

[0005] The above-mentioned stringing method needs to carry the film strip and the cell unit by the film strip carrying mechanism and the cell carrying mechanism respectively, which increases the complexity and the cost of the equipment. CONTENT OF THE UTILITY MODEL

[0048] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0049] As described in the background section, in order to improve the stringing efficiency and quality of the battery string, a feasible solution is to first transport and stack the film strip on the carrying table to the battery piece on the first conveying line by the film strip transport mechanism to obtain the battery unit. Then the battery unit is transported from the first conveying line to the second conveying line by the battery transport mechanism, and the battery unit is transported to the subsequent stringing station by the second conveying line, and finally the battery unit and the welding strip group are laid according to the stringing rule by the battery piece stringing device, and the film strip automatically enters between the adjacent battery pieces during the stringing process.

[0050] The above-mentioned stringing method needs to transport the film strip and the battery unit by the film strip transport mechanism and the battery transport mechanism respectively, which increases the complexity and equipment cost.

[0051] In order to solve the problem, the present application provides a transport mechanism 10. As shown in Figure 1 The transport mechanism 10 of the present application includes a translation driving part 1, a first transport part 2 and a second transport part 3, wherein:

[0052] The first transport part 2 and the second transport part 3 are connected on the moving part of the translation driving part 1 along the first direction (such as the X direction).

[0053] The translation driving part 1 is configured to simultaneously drive the first transport part 2 and the second transport part 3 to translate along the first direction, so as to drive the second transport part 3 to transport the i-th group of battery units located at the second position to the third position, the i-th group of battery units including the i-th group of battery pieces and the film strip stacked on the edge of the i-th group of battery pieces, and drive the first transport part 2 to transport the film strip located at the first position to the latest conveying i+1-th group of battery pieces located at the second position to obtain the i+1-th group of battery units.

[0054] The transport mechanism 10 provided by the present application is driven by the translation driving part 1 to synchronously drive the first transport part 2 and the second transport part 3. While the second transport part 3 transports the i-th group of battery units located at the second position to the third position, the first transport part 2 can transport the film strip located at the first position to the latest conveying i+1-th group of battery pieces located at the second position, thereby obtaining the i+1-th group of battery units.

[0055] It can be seen that the carrying mechanism 10 can carry the battery cells and stack the film strips, thereby reducing the complexity and cost of the equipment. In particular, the carrying mechanism carries the next batch of film strips located at the first position to the latest batch of battery pieces located at the second position while carrying the current batch of battery cells located at the second position to the third position, thereby obtaining the next batch of battery cells, accelerating the work rhythm, and improving the film stacking efficiency.

[0056] The translation driving part 1 can adopt an existing linear module. The first carrying part 2 and the second carrying part 3 are installed on the same sliding table of the linear module. The translation driving part 1 can also be a motor matched with a belt assembly or a screw nut mechanism, etc. The translation driving part 1 can only drive the first carrying part 2 and the second carrying part 3 to translate in the first direction at the same time.

[0057] Optionally, the first position, the second position and the third position are arranged in sequence along the first direction, and the distance between the first position and the second position and the distance between the second position and the third position are matched with the distance between the first carrying part 2 and the second carrying part 3. Each group of battery cells includes n battery pieces arranged at intervals and n film strips stacked one by one at the edges of the n battery pieces. n can be 1, 2, 3 or other natural numbers.

[0058] By setting the distance between the first position and the second position and the distance between the second position and the third position to be matched with the distance between the first carrying part 2 and the second carrying part 3, the first carrying part 2 can be moved to the first position when the second carrying part 3 is moved to the second position. The first carrying part 2 can be moved to the second position when the second carrying part 3 is moved to the third position.

[0059] In this way, the second carrying part 3 can carry the i-th group of battery cells located at the second position to the third position while the first carrying part 2 can synchronously carry the film strips located at the first position to the latest batch of battery pieces located at the i+1-th group of battery pieces at the second position.

[0060] As shown in Figures 1 to 2 Optionally, the first carrying part 2 includes a first lifting driving module 21, a first mounting frame 22 and n first adsorption assemblies 23. The first lifting driving module 21 is connected to the moving part of the translation driving part 1. The first mounting frame 22 is connected to the moving part of the first lifting driving module 21, and the first lifting driving module 21 is used to drive the first mounting frame 22 to lift. The n first adsorption assemblies 23 are arranged at intervals along the second direction (such as the Y direction) on the first mounting frame 22. Each first adsorption assembly 23 is used to adsorb a film strip. n is greater than or equal to 2, and the second direction is perpendicular to the first direction.

[0061] By setting the first conveying part 2, the first conveying part 2 can convey at least two film strips one by one to at least two battery pieces at the second position each time, so as to obtain at least two battery cells, and improve the film stacking efficiency.

[0062] The first lifting driving module 21 can adopt various linear driving modules capable of driving the first mounting frame 22 to lift, such as a motor matched with a screw nut mechanism, a cylinder, etc.

[0063] As shown in Figure 2 Optionally, the first conveying part 2 further comprises a distance adjusting assembly 24 arranged on the first mounting frame 22, and the distance adjusting assembly 24 is configured to adjust the distance between the n first adsorption assemblies 23.

[0064] By arranging the distance adjusting assembly 24, the distance between the n first adsorption assemblies 23 can be flexibly adjusted, so as to ensure that the n first adsorption assemblies 23 can pick up n film strips from the first position, and the distance between the n film strips can be adjusted according to the requirement, so that the n film strips can be stacked one by one on the edges of the n battery pieces at the second position. That is, the first conveying part 2 can be compatible with n film strips to be picked up with different distances, and compatible with n battery pieces to be stacked with film strips with different distances.

[0065] The distance adjusting assembly 24 can adopt various distance adjusting driving modules with various structures, as long as it can drive the n first adsorption assemblies 23 to slide towards the middle and apart from each other.

[0066] Figure 2 In the embodiment shown, n=3, that is, the first conveying part 2 comprises three first adsorption assemblies 23. Among them, the first adsorption assembly 23 at the middle position is fixedly arranged on the first mounting frame 22, and the two first adsorption assemblies 23 at the two side positions are both slidingly connected to the first mounting frame 22. The distance adjusting assembly 24 is configured to drive the two first adsorption assemblies 23 at the two side positions to slide towards the middle and apart from each other along the second direction synchronously.

[0067] Optionally, the distance adjusting assembly 24 comprises a first linear driving member 241 and a second linear driving member 242, wherein the first linear driving member 241 and the second linear driving member 242 are respectively connected to one of the two first adsorption assemblies 23 at the two side positions. The first linear driving member 241 and the second linear driving member 242 are configured to drive the two first adsorption assemblies 23 at the two side positions to slide towards the middle and apart from each other, so as to adjust the distance between the three first adsorption assemblies 23.

[0068] Particularly, the first linear driving member 241 and the second linear driving member 242 respectively and independently drive one of the two first adsorption assemblies 23 located at the two side positions to slide, so that the adjustment flexibility of the spacing between the three first adsorption assemblies 23 can be further improved. For example, the spacing between the first adsorption assembly 23 located at the first side and the first adsorption assembly 23 located at the middle position is adjusted to be a first spacing, and the spacing between the first adsorption assembly 23 located at the second side and the first adsorption assembly 23 located at the middle position is adjusted to be a second spacing which is not equal to or equal to the first spacing.

[0069] The first linear driving member 241 and the second linear driving member 242 may, for example, be a gas cylinder, an electric cylinder, or a motor combined with a screw nut mechanism, etc.

[0070] As shown in Figures 3 to 4 Optionally, the first adsorption assembly 23 comprises a connecting plate 231, an adsorption strip 232, and a buffer connecting member 233, wherein the connecting plate 231 is connected to the first mounting frame 22. The adsorption strip 232 is connected to the connecting plate 231 in a vertically floating manner through the buffer connecting member 233 and is located below the connecting plate 231. The adsorption strip 232 extends along the first direction and is used for adsorbing the film strip.

[0071] Since the adsorption strip 232 is connected to the connecting plate 231 in a vertically floating manner through the buffer connecting member 233, when the first lifting driving module 21 drives the first mounting frame 22 to descend towards the film strip to be picked up, the adsorption strip 232 is elastically pressed onto the film strip, so that the adsorption strip 232 can be in full contact with the film strip, ensuring that the film strip is completely adsorbed onto the adsorption strip 232. When the first lifting driving module 21 drives the first mounting frame 22 to descend towards the battery piece, the adsorption strip 232 can elastically press the film strip adsorbed thereon onto the battery piece, ensuring that the film strip can be fully attached to the battery piece and avoiding excessive pressure from causing damage to the battery piece.

[0072] The buffer connecting member 233 may, for example, be a spring assembly that can contract in the vertical direction after being pressed.

[0073] Optionally, the adsorption strip 232 is provided with a gas cavity connected to an external air extraction device, and the lower surface of the adsorption strip 232 is densely provided with adsorption holes in communication with the gas cavity. The air extraction device extracts air from the gas cavity to generate negative pressure in the gas cavity, and finally generates adsorption force in the adsorption holes.

[0074] As shown in Figure 1As shown, optionally, the second carrying part 3 comprises a second lifting driving module 31, a second mounting frame 32 and n second adsorption assemblies 33, wherein: the second lifting driving module 31 is connected to the movable part of the translation driving part 1, the second mounting frame 32 is connected to the movable part of the second lifting driving module 31, and the second lifting driving module is used to drive the second mounting frame 32 to lift. The n second adsorption assemblies 33 are arranged on the second mounting frame 32 in a second direction (such as the Y direction) and are spaced apart from each other, and each second adsorption assembly 33 is used to adsorb one battery unit. Wherein, n≥2, and the second direction is perpendicular to the first direction.

[0075] By providing the second carrying part 3, at least two battery units can be carried from the second position to the third position each time, thereby improving the carrying efficiency of the battery units.

[0076] Optionally, the second adsorption assembly 33 is a suction cup assembly. The suction cup assembly can stably adsorb and carry the battery unit, and prevent damage to the battery sheet.

[0077] The application also provides a battery sheet film stacking device. As shown, Figure 5 The battery sheet film stacking device in the embodiment of the application comprises a bearing table 20, a first conveying line 30, a second conveying line 40 and the carrying mechanism 10 in any one of the above embodiments, wherein: the bearing table 20 is located at the first position and is used to bear the film strip. The first conveying line 30 is used to convey the battery sheet to be stacked with film to the second position, and the first conveying line 30 is a heated conveying line and is configured to heat the battery sheet thereon. The second conveying line 40 is provided with a third position and is used to receive the battery unit carried by the carrying mechanism 10 and convey the battery unit to the subsequent process.

[0078] The first conveying line 30 is a heated conveying line, specifically, the first conveying line 30 comprises a conveying belt for conveying the battery sheet, and the lower surface of the conveying belt is attached to a heating plate, and a heating rod is embedded in the heating plate. The heating rod is used to heat the heating plate, and the heating plate transmits heat to the conveying belt and the battery sheet on the conveying belt, thereby achieving heating of the battery sheet. When the film strip is stacked on the edge of the battery sheet, the film strip is pasted on the battery sheet due to the heat generated by the film strip, thereby forming a battery unit.

[0079] The battery sheet film stacking device in the embodiment of the application can automatically stack the film strip on the battery sheet, thereby obtaining the battery unit and conveying the battery unit to the subsequent stringing station. In this way, in the subsequent stringing process, the battery unit and the group of welding strips are laid into a string according to the predetermined stringing rule, so that the film strip segment enters the corresponding inter-sheet position, thereby eliminating the operation of lifting the battery sheet to insert the film in the subsequent stringing process, avoiding the risk of hidden cracks or broken pieces of the battery sheet caused by the film insertion operation, and ensuring the quality of the battery stringing.

[0080] In particular, the carrying mechanism 10 carries the next batch of the film strip on the carrying table 20 to the next batch of the battery piece on the first conveying line 30 at the second position at the same time when it carries the current batch of the battery piece on the first conveying line 30 to the second conveying line 40, so that the next batch of the battery piece is obtained, thereby speeding up the work rhythm and improving the efficiency of the film stacking of the battery piece.
