Description

Technical field:

[0001] The utility model belongs to the technical field of battery cell production, and particularly relates to a battery cell screen printing detection table. Background technology:

[0002] During the production process of cells in solar cells, electrodes need to be formed on the cells. The formation of electrodes is generally completed through a screen printing process.

[0003] After screen printing, the battery cells need to be photographed to check whether the electrodes are complete. If there are defects in the electrodes, they can be discovered in time and the defective products can be selected. Since the camera is set on the product conveyor line, when the product runs to the camera, due to inertia, the product will move a distance from running to stopping on the conveyor line, which often causes the position of the product when it stops to deviate from the position directly below the camera, and it will be impossible to take a full picture of the product, affecting the camera inspection effect. In addition, under natural light conditions, the photos taken by the camera cannot clearly display the battery cells and the electrode structures on the battery cells, which affects the inspection effect.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The negative pressure airway in the test bench can be used to absorb and fix the battery cells, preventing the battery cells from being unable to face the camera due to inertia.

[0020] like Figure 1-3 As shown, a battery cell screen printing inspection table includes a base 1, a table top 2, a cover plate 3, a negative pressure airway 4, and a baffle 5; the base 1 is symmetrically provided with slide grooves 10, the slide grooves 10 cooperate with the conveyor line, and the base 1 moves on the conveyor line through the slide grooves 10; the slide grooves 10 divide the top of the base 1 into a middle part 11 and a side part 12, and the side parts 12 are symmetrically arranged on both sides of the middle part 11, and the base 1 is located below the camera device; the top of the base 1 is provided with a table top 2, and the table top 2 includes a middle table top 20 and a side table top 21, the middle table top 20 is arranged on the middle part 11, and the side table top 21 is arranged on the side part 12, and the middle table top 20 and the side table top 21 are covered with corresponding cover plates 3; baffles 5 are provided on the base 1 at both ends of the middle table top 20 and the side table top 21, and the height of the baffle 5 is flush with the cover plate 3, and is used to protect the edges of the table top 2 and the cover plate 3 at both ends.

[0021] A negative pressure airway 4 is arranged in the base 1, the table top 2 and the cover plate 3, and the negative pressure airway 4 includes a main airway 40, a middle bronchus 41, a side bronchus 42 and an air hole 43. The base 1 is provided with a main airway 40, and the main airway 40 is connected to an external negative pressure generator. The middle table top 20 and the side table top 21 are provided with corresponding middle bronchus 41 and side bronchus 42 as needed. The middle bronchus 41 and the side bronchus 42 are respectively connected to the corresponding main airway 40. The cover plate 3 is provided with air holes 43, and the air holes 43 are evenly distributed along the corresponding middle bronchus 41 and the side bronchus 42; an adsorption force is formed on the surface of the cover plate 3 of the side portion 12 by the external negative pressure generator-main airway 40-side bronchus 42-air hole 43, and an adsorption force is formed on the surface of the cover plate 3 of the middle portion 11 by the external negative pressure generator-main airway 40-middle bronchus 41-air hole 43.

[0022] A light source is arranged below the base 1, and the table top 2 and the cover plate 3 are made of acrylic plates.

[0023] According to the position of the photographing device, the position of the inspection platform is moved on the conveyor line so that the inspection platform faces the photographing device. The conveyor line starts to convey the battery cell. A grating detection mechanism is set on the conveyor line in front of the inspection platform. When the battery cell runs to the inspection platform, the conveyor line stops and the external negative pressure generator is started. The negative pressure airway 4 forms an adsorption force on the surface of the cover plate 3 to adsorb the battery cell on the surface of the cover plate 3 and fix it to prevent the battery cell from being unable to face the photographing device due to inertia, thereby ensuring the positioning position of the battery cell.
