DETAILED DESCRIPTION

[0019] The technical solution and technical effects of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0020] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature can include the first and second features directly contacting, and can also include the first and second features not directly contacting but contacting through another feature between them. Moreover, the first feature "above", "above" and "above" the second feature include the first feature directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0021] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must be provided with a specific direction, constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present utility model. It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish the first feature from the second feature, and do not necessarily require or imply any such actual relationship or order between these features.

[0022] like Figure 1-Figure 3As shown, the utility model provides a battery string conveying mechanism, which includes: a frame 10 and a conveyor belt 20 installed on the frame 10, the conveyor belt 20 includes a vertical conveying section 21 and a horizontal conveying section 22, the conveyor belt 20 is conveyed from the vertical conveying section 21 to the horizontal conveying section 22, and an adsorption support platform 30 is provided at the front end of the horizontal conveying section 22, and the adsorption support platform 30 is connected to the frame 10; along a rotation direction perpendicular to the conveyor belt 20, a plurality of adsorption holes 31 and a plurality of mounting grooves are linearly provided on the top of the adsorption support platform 30, and a roller 32 is rotatably provided in each mounting groove, and the top end of the roller 32 is higher than the top surface of the adsorption support platform 30, and the rotation direction of the roller 32 is the same as the rotation direction of the conveyor belt 20.

[0023] In the utility model, a plurality of adsorption plates are laid on the frame 10, and the adsorption plates are in contact with the vertical conveying section 21 and the horizontal conveying section 22. A negative pressure chamber is provided inside each adsorption plate. The surface of the adsorption plate in contact with the vertical conveying section 21 and the horizontal conveying section 22 is provided with strip holes, and the strip holes are connected with the adsorption chamber. There are through holes on the conveyor belt 20. When the conveyor belt 20 rotates, the strip holes on the adsorption plate are connected with the through holes on the conveyor belt 20, so that the vertical conveying section 21 and the horizontal conveying section 22 generate adsorption force. The battery string conveying mechanism is used to lay and convey the battery strings. The vertical conveying section 21 can absorb the hot melt adhesive film required on the back of the battery string and convey it to the horizontal conveying section 22. When laying the battery cells on the battery string conveying mechanism, the front half of the battery cell is located on the horizontal conveying section 22, and the rear half is supported by the adsorption support platform 30. The adsorption force generated by the adsorption hole 31 can keep the rear half of the battery cell stable. The roller 32 supports the rear half of the battery cell so that there is a gap between the rear half of the battery cell and the top surface of the adsorption support platform 30. When the horizontal conveying section 22 conveys forward, the rear half of the battery cell moves forward, and the roller 32 rotates accordingly. The battery cell will not scratch the top surface of the adsorption support platform 30 and will not be damaged.

[0024] In an optional embodiment of the present invention, a plurality of adsorption holes 31 and a plurality of rollers 32 are arranged in a staggered manner so that the force on the rear half of the battery cell is relatively uniform, thereby ensuring that the battery cell can move smoothly when the conveyor belt 20 rotates.

[0025] In an optional embodiment of the utility model, a plurality of welding tape guide grooves 33 are provided on the adsorption support platform 30, and the adsorption hole 31 or the roller 32 is provided between any two adjacent welding tape guide grooves 33. The welding tape guide groove 33 runs through two opposite surfaces of the adsorption support platform 30, and the welding tape guide groove 33 corresponds to the position of the grid line on the battery cell. When the welding tape is laid on the battery string conveying mechanism, the front half of the welding tape is located on the horizontal conveying section 22. When the horizontal conveying section 22 is conveyed forward, the rear half of the welding tape moves forward and passes through the welding tape guide groove 33. The welding tape guide groove 33 plays a guiding role to prevent the welding tape from being offset when moving.

[0026] In an optional embodiment of the present invention, an air cavity is provided inside the adsorption support platform 30, and an exhaust hole connected to the air cavity is provided at the bottom of the adsorption support platform 30. All adsorption holes 31 are connected to the air cavity. When the gas in the air cavity is extracted from the exhaust hole, the adsorption holes 31 will generate adsorption force.

[0027] In an optional embodiment of the utility model, the battery string conveying mechanism also includes a driving wheel 11, a first driven wheel 12, a second driven wheel 13 and a third driven wheel 14 arranged on the frame 10, and the conveyor belt 20 is sequentially mounted on the driving wheel 11, the first driven wheel 12, the second driven wheel 13 and the third driven wheel 14, the portion of the conveyor belt 20 located between the first driven wheel 12 and the second driven wheel 13 is a vertical conveying section 21, and the portion of the conveyor belt 20 located between the second driven wheel 13 and the third driven wheel 14 is a horizontal conveying section 22, the first driven wheel 12 is located below the second driven wheel 13, and the third driven wheel 14 is adjacent to and arranged above the driving wheel 11, the wheel diameter of the driving wheel 11 is larger than the wheel diameter of the third driven wheel 14, and the driving wheel 11 is connected to the motor installed on the frame 10, and when the driving wheel 11 rotates, it drives the first driven wheel 12, the second driven wheel 13, the third driven wheel 14 and the conveyor belt 20 to rotate. After the hot melt adhesive film, welding ribbon and battery cells are laid and heated according to the battery string structure to form a battery string, they are transferred to the next station, and the horizontal conveying section 22 is docked with the conveying device at the next station. Since the hot melt adhesive film will adhere to the battery cells and the conveyor belt 20 at the same time after being heated, a third driven wheel 14 with a smaller diameter is arranged above the driving wheel 11, which can increase the peeling angle between the hot melt adhesive film and the conveyor belt 20, so that the end of the battery string can be easily separated from the conveyor belt when passing through the third driven wheel 14 without being caught in the gap between the battery string conveying mechanism and the conveyor device at the next station, thereby avoiding damage to the battery string and shutdown failure.

[0028] In an optional embodiment of the present invention, the surface of the adsorption support platform 30 close to the second driven wheel 13 is an inwardly concave curved surface, which can reduce the distance between the adsorption support platform 30 and the conveyor belt 20 and improve the stability of the battery cell when it moves with the conveyor belt 20.

[0029] In an optional embodiment of the utility model, a tensioning wheel 15 is provided next to the driving wheel 11, so that the area of ​​the driving wheel 11 wrapped by the conveyor belt 20 exceeds half of the curved surface area of ​​the driving wheel 11, thereby increasing the static friction between the conveyor belt 20 and the driving wheel 11.

[0030] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
