Description

Technical Field

[0001] The present application belongs to the technical field of photovoltaic cell production, and in particular relates to a conveying and detecting mechanism and a cell sheet gluing device. Background Art

[0002] In order to solve the problem of cracks easily caused by high-temperature welding, a low-temperature welding process has emerged in the industry. It first applies glue to the specified position on the battery cell, then strings the soldering ribbon and the battery cell together, and then heats at a low temperature to achieve positional contact between the battery cell and the soldering ribbon through adhesive bonding to form a battery string. Then, when the components are laminated, the soldering ribbon and the battery cell achieve ohmic contact.

[0003] In order to ensure the welding quality between the battery cells and the welding strips, the battery cells need to be photographed and inspected by the inspection mechanism after the glue is applied. The existing inspection mechanism usually needs to set up a special inspection table. During the inspection, the transportation mechanism first transports the battery cells after the glue is applied to the inspection table. After the photographed inspection, the inspected battery cells are transported to the conveyor line for further transportation and process processing. Obviously, the existing inspection mechanism needs to frequently switch between the inspection table and the conveyor line when photographing and inspecting the battery cells after the glue is applied, which has the disadvantage of low inspection efficiency.

[0073] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0074] In order to solve the problem of cracks easily caused by high-temperature welding, a low-temperature welding process has emerged in the industry. It first applies glue to the specified position on the battery cell, then strings the soldering ribbon and the battery cell together, and then heats at a low temperature to achieve positional contact between the battery cell and the soldering ribbon through adhesive bonding to form a battery string. Then, when the components are laminated, the soldering ribbon and the battery cell achieve ohmic contact.

[0075] In order to ensure the welding quality between the battery cells and the welding strips, the battery cells need to be photographed and inspected by the inspection mechanism after the glue is applied. The existing inspection mechanism usually needs to set up a special inspection table. During the inspection, the transportation mechanism first transports the battery cells after the glue is applied to the inspection table. After the photographed inspection, the inspected battery cells are transported to the conveyor line for further transportation and process processing. Obviously, the existing inspection mechanism needs to frequently switch between the inspection table and the conveyor line when photographing and inspecting the battery cells after the glue is applied, which has the disadvantage of low inspection efficiency.

[0076] Therefore, in the first aspect, the present application proposes a conveying detection mechanism, see Figure 1 As shown, the conveying and inspection mechanism proposed in the embodiment of the present application includes a transfer mechanism 10, a conveying component 20, a detection camera 30, a light source component 40 and a reflective component 50, wherein: the transfer mechanism 10 is located in the front lane of the conveying component 20, and the transfer mechanism 10 transfers the battery cell after glue application to the input end of the conveying component 20; an inspection station is provided at the input end of the conveying component 20; the inspection camera 30 is located above the inspection station, and the inspection camera 30 is configured to perform photo inspection on the battery cell after glue application at the inspection station; the light source component 40 is arranged at the inspection station, and the light source component 40 is configured to provide fill light when the inspection camera 30 takes a photo of the battery cell at the inspection station; the reflective component 50 is arranged at the inspection station, and the reflective component 50 is configured to reflect the light of the light source component 40 to the glue application surface and edge of the battery cell at the inspection station, so that the glue application marks on the surface of the battery cell at the inspection station and the pattern of the edge of the battery cell photographed by the inspection camera 30 are clear.

[0077] It can be seen that the conveying and inspection mechanism provided in the present application sets an inspection station on the conveying component 20, and the inspection camera 30 is set above the inspection station. The inspection camera 30 is used to implement photographic inspection on the battery cell after gluing at the inspection station, thereby realizing online photographic inspection of the battery cell after gluing on the conveying component 20. There is no need to set up a separate inspection table, which improves the inspection efficiency of the battery cell after gluing, occupies less space, and reduces production costs. At the same time, by setting a reflective component 50 at the inspection station, the light of the light source component 40 is reflected to the gluing surface and edge of the battery cell at the inspection station, so that the glue marks on the surface of the battery cell at the inspection station and the pattern of the edge of the battery cell photographed by the inspection camera 30 are clear, which is conducive to distinguishing glue points and improving the inspection accuracy.

[0078] See also Figures 1 to 4 As shown, as an embodiment, the light source assembly 40 includes two bar light sources 41 for providing light to the detection station. The two bar light sources 41 are respectively arranged on both sides of the detection station, and the two bar light sources 41 extend along the conveying direction of the conveying assembly 20.

[0079] It can be seen that by arranging the strip light sources 41 extending along the conveying direction of the conveying assembly 20 on both sides of the detection station, the lighting effect of the light source assembly 40 is ensured.

[0080] As an embodiment, the conveying detection mechanism further includes two light shielding plates 51 ( Figures 2 to 4 Only one shading plate 51 is shown in the figure, and the two shading plates 51 are respectively installed above the two bar-shaped light sources 41 to respectively block the light of the opposite bar-shaped light sources 41.

[0081] It can be seen that by providing two shading plates 51 , it is possible to shield the light from the opposite strip light source 41 , thereby preventing the light generated by the strip light source 41 from shining on the workers in the workshop.

[0082] As another optional embodiment, the light source assembly 40 may also include a top light source, which is disposed above the detection station and emits light downward to illuminate the battery cell located at the detection station. This embodiment does not require the provision of a shading plate 51.

[0083] Two implementations of the light source assembly 40 are shown above. Optionally, the two implementations of the light source assembly 40 can be combined, that is, the light source assembly 40 includes a top light source and two strip light sources 41, which illuminate the battery cells located at the inspection station at the same time.

[0084] As an embodiment, the reflective assembly 50 includes a first reflective base plate 52, the conveying assembly 20 includes a light-transmitting conveyor belt, the first reflective base plate 52 is located below the conveyor belt of the detection station, and the first reflective base plate 52 is used to reflect the light emitted by the light source assembly 40 upward.

[0085] It can be seen that by providing the first reflective bottom plate 52 and the light-transmitting conveyor belt, the light emitted by the light source assembly 40 is reflected upward, which facilitates the identification of the edge of the battery cell and improves the clarity of the photography of the glue marks on the surface of the battery cell.

[0086] See also Figure 1 , Figure 3 and Figure 7 As shown, as an embodiment, the transfer mechanism 10 is a stepping beam structure, and the transfer mechanism 10 includes a stepping driver 11 and two support frames 12. The driving end of the stepping driver 11 is connected to the two support frames 12 to drive the two support frames 12 to step; the reflective assembly 50 also includes a second reflective base plate 53 and a third reflective base plate 54, and the second reflective base plate 53 and the third reflective base plate 54 are respectively installed at intervals on both sides of the first reflective base plate 52, and a first stepping gap 55 is formed between the first reflective base plate 52 and the second reflective base plate 53, and a second stepping gap 56 is formed between the first reflective base plate 52 and the third reflective base plate 54. After stepping, the two support frames 12 of the transfer mechanism 10 are respectively inserted into the first stepping gap 55 and the second stepping gap 56; the second reflective base plate 53 and the third reflective base plate 54 are respectively located directly below the two side edges of the battery cell carried by the conveyor belt at the detection station to reflect the light emitted by the light source assembly 40 upward.

[0087] Specifically, the stepper driver 11 is configured to drive the two support frames 12 to lift and translate. The stepper driver 11 includes a translation module 110 and a lifting module 111. The lifting module 111 is installed at the driving end of the translation module 110, and the two support frames 12 are installed at the driving end of the lifting module 111. The translation module 110 is used to drive the two support frames 12 to translate in the horizontal direction, and the lifting module 111 is used to drive the two support frames 12 to lift and lower in the height direction.

[0088] It can be seen that the transportation of the battery cell is realized through the cooperation of the translation module 110, the lifting module 111 and the two support frames 12. The battery cell is subjected to little force when being taken and placed, which can effectively reduce the risk of battery cell fragments and hidden cracks; by setting the second reflective base plate 53 and the third reflective base plate 54, a step gap for avoiding the two support frames 12 is formed between the first reflective base plate 52 and the second reflective base plate 53 and between the first reflective base plate 52 and the third reflective base plate 54; at the same time, the second reflective base plate 53 and the third reflective base plate 53 are arranged directly below the two side edges of the battery cell, so as to reflect the light emitted by the light source assembly 40 upward, so that the two side edges of the battery cell are further easy to identify.

[0089] See also Figure 1 , Figure 5 and Figure 6As shown, as an embodiment, an adsorption component 57 is provided on the reflective component 50, and adsorption holes are opened on the conveyor belt. The adsorption component 57 is connected to the adsorption holes of the conveyor belt to provide downward adsorption force to the battery cells carried on the conveyor belt.

[0090] Specifically, the adsorption component 57 is arranged on the first reflective base plate 52, and the adsorption component 57 includes a plurality of negative pressure adsorption grooves 570, an air suction channel 571 and an air suction device. The plurality of negative pressure adsorption grooves 570 are opened on the first reflective base plate 52, and the plurality of negative pressure adsorption grooves 570 are arranged in parallel and extend along the length direction of the first reflective base plate 52. The first end of the air suction channel 571 is connected with the plurality of negative pressure adsorption grooves 570, and the second end of the air suction channel 571 is connected with the air suction device; the air suction device extracts air in the air suction channel 571 to generate negative pressure in the air suction channel 571, and adsorbs the battery cells on the conveyor belt toward the conveying surface of the conveyor belt through the plurality of negative pressure adsorption grooves 570 and the adsorption holes on the conveyor belt.

[0091] It can be seen that by providing the adsorption assembly 57, the battery cells carried on the conveyor belt are adsorbed downward, the friction between the battery cells and the conveyor belt is increased, and the battery cells are prevented from slipping when being conveyed at high speed.

[0092] See also Figure 1 , Figure 4 and Figure 8 As shown, as an embodiment, the conveying assembly 20 includes a conveying frame 21, an active roller 22, a driven roller 23, a light-transmitting conveying belt and a first driving member 24, wherein: the conveying frame 21 is along a first horizontal direction ( Figure 1 The driving roller 22 is rotatably mounted on the first end of the conveying frame 21, and the driven roller 23 is rotatably mounted on the second end of the conveying frame 21. The conveying belt is mounted around the driving roller 22 and the driven roller 23. The fixed end of the first driving member 24 is mounted on the conveying frame 21, and the driving end of the first driving member 24 is connected to the driving roller 22. The first driving member 24 is configured to drive the driving roller 22 to rotate, so as to cooperate with the driven roller 23 to drive the conveying belt to rotate.

[0093] Specifically, the conveying assembly 20 also includes a movable member 25 and a third driving member 26. The driven roller 23 is rotatably mounted on the movable member 25. The movable member 25 can be reciprocatingly mounted on the first end of the conveying frame along the first horizontal direction. The fixed end of the third driving member 26 is mounted on the conveying frame 21. The driving end of the third driving member 26 is connected to the movable member 25. The third driving member 26 is configured to drive the movable member 25 to move closer to or away from the active roller 22 along the first horizontal direction; the third driving member 26 drives the movable member 25 to move away from the active roller 22 along the first horizontal direction, so as to drive the driven roller 23 to move away from the active roller 22, thereby tightening the conveyor belts on the active roller 22 and the driven roller 23; the third driving member 26 drives the movable member 25 to move closer to the active roller 22 along the first horizontal direction, so as to drive the driven roller 23 to move closer to the active roller 22, thereby loosening the conveyor belts on the active roller 22 and the driven roller 23; this facilitates the disassembly and assembly of the conveyor belt; and also keeps the conveyor belt at a constant tension. Optionally, the third driving member 26 can be a low-cost, easy-to-maintain cylinder, which can be connected to the air circuit to create a certain air pressure inside the cylinder, thereby driving the driven roller 23 away from the active roller 22 and continuously tightening the conveyor belt.

[0094] It can be seen that through the cooperation of the first driving member 24, the active roller 22, the driven roller 23 and the light-transmitting conveyor belt, the conveyor belt can be driven to rotate, and then the battery cells on the conveyor belt are conveyed, providing a conveying component 20 with a simple structure and smooth conveying.

[0095] As an embodiment, the conveying detection mechanism also includes a buffer mechanism arranged at the starting end of the conveying assembly 20. The buffer mechanism can be installed on the conveying frame 21 or the frame / machine platform. The buffer mechanism includes a lifting drive and a bracket. The bracket is installed on the driving end of the lifting drive. When the lifting drive drives the bracket to rise, the battery cell delivered by the stepping beam can be received; when the lifting drive drives the bracket to lower, the battery cell can be placed on the conveying assembly 20. Such a setting can connect the front and rear production rhythms, so that the stepping beam can withdraw to the front station as soon as possible to continue to transport the battery cells, thereby improving production efficiency.

[0096] As an embodiment, the conveying detection mechanism also includes a PL detection component, which includes a PL light source and a PL camera. The PL detection component is arranged at the rear of the detection camera 30 and is located above the conveying component 20.

[0098] It can be seen that by setting the regularization component 60 on the inspection station, the battery cells after glue application on the inspection station can be regularized before the photographic inspection to ensure that the battery cells after glue application are in the preset photographic position, which is beneficial to improve the inspection accuracy.
