Description

Positioning device for battery housing assembly Technical Field

[0001] The present invention belongs to the technical field of battery production tools, and in particular relates to a positioning device for battery shell assembly. Background Art

[0002] Battery casing assembly refers to a relatively late step in the lithium battery production process. The general operation is: install the battery module, battery management system, heat dissipation system and other structures in the casing, then install the connector on the cover, and finally fasten the casing and cover.

[0003] Therefore, the most basic function of the positioning device used for battery shell assembly is to stably support the shell, fully and appropriately clamp the shell, and prevent the shell from shifting or tipping over during the assembly process.

[0004] On the other hand, the relatively advanced and practical positioning device may also include the following functions, such as: relatively convenient and fast shell release function, collection function of garbage such as tape on the surface of the device, and elastic clamping to protect the shell function.

[0005] For example, a Chinese utility model patent with patent publication number CN218101378U and publication date 2022.12.20 discloses a lithium battery PACK assembly positioning mechanism, including a fixed seat, and a movable positioning mechanism is provided at both ends of the interior of the fixed seat. The movable positioning mechanism includes a motor, a screw, a bearing, a slider, an installation groove, a clamping block and a clamping pad. The motor is fixedly installed on both sides of the fixed seat, and the output end of the motor is transmission-connected with a screw. The other end of the screw is fixedly connected to the inside of the bearing, and the bearing is fixedly installed on the inner wall of the installation groove.

[0006] The structural principle and advantages of the positioning mechanism in this utility model patent are as follows: a cleaning mechanism is provided to clean the dust accumulated on the surface of the lithium battery, thereby reducing the impact of subsequent use during assembly of the lithium battery and reducing unnecessary damage.

[0007] However, in actual use, the positioning mechanism still has at least the following shortcomings, which are also the technical problems to be solved by the present invention, namely:

[0008] Its clamping, positioning and dust cleaning functions require a motor, an air pump and an electric telescopic rod to achieve, which is very complicated and costly.

[0009] Therefore, in summary, there is an urgent need for a new positioning device with a relatively simple structure and relatively low production and use costs, so as to be used in the shell assembly step of lithium battery production. Summary of the Invention

[0010] The present invention provides a positioning device for assembling a battery shell, which can be configured by arranging a garbage blocking frame unit, a torsion spring rotating plate unit, a fixed frame unit, and a standby brush unit on a slotted bottom plate unit, so that: 1. after the device is externally connected to a blower, assembly garbage mainly located between two torsion spring rotating plate units can be blown into the slotted bottom plate unit simply, quickly, and at low cost, thereby providing a neat operating environment for assembling the battery shell; 2. the two torsion spring rotating plate units and a fixed frame unit can together fully and appropriately clamp the positioning shell; 3. the standby brush unit can both clean up garbage and pull the torsion spring rotating plate unit, so that the device has a stable standby state.

[0012] A further preferred technical solution is that the slotted bottom plate unit includes a flat plate, and a garbage receiving groove provided on an upper surface of the flat plate and located between the garbage blocking frame unit and the fixed frame unit.

[0013] A further preferred technical solution is that the vertical cross-section of the garbage collection trough is in the shape of an inverted triangle.

[0014] A further preferred technical solution is that the garbage blocking frame unit includes a vertical side plate arranged on the upper surface of the flat plate, and two end plates arranged on the vertical side plate and respectively located at both sides of the garbage receiving trough.

[0015] A further preferred technical solution is that the garbage blocking frame unit further includes a mounting groove provided on the upper surface of the end plate and used for inserting the brush body unit in the waiting position.

[0016] A further preferred technical solution is that the torsion spring rotating plate unit includes a vertical rod arranged on the upper surface of the flat plate, a vertical perforated plate sleeved on the vertical rod and used to clamp the shell, and a torsion spring sleeved on the vertical rod and located in the vertical perforated plate.

DETAILED DESCRIPTION

[0033] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0034] As shown in Figures 1-8, a positioning device for assembling a battery shell comprises a slotted bottom plate unit 1 for receiving and assembling garbage a, a garbage blocking frame unit 2 arranged on the slotted bottom plate unit 1, two torsion spring rotating plate units 3 arranged on the slotted bottom plate unit 1 and used for clamping the shell b, a fixed frame unit 4 arranged on the two torsion spring rotating plate units 3 and used for laterally supporting the shell b and installing the air duct c, and a standby brush body unit 5 respectively arranged at both ends of the garbage blocking frame unit 2 and used for plugging the torsion spring rotating plate unit 3.

[0035] In this embodiment, the long-term idle state of the positioning device is: the standby brush body unit 5 is installed on the garbage blocking frame unit 2, but is separated from the torsion spring rotating plate unit 3, the torsion spring in the torsion spring rotating plate unit 3 is in a relaxed state, and the air duct c is not connected to the fixed frame unit 4.

[0036] In this embodiment, the standby state of the positioning device is: the standby brush body unit 5 is installed on the garbage blocking frame unit 2 and is connected to the torsion spring rotating plate unit 3. The distance between the two torsion spring rotating plate units 3 is pulled to be larger than the size of the shell b, which is convenient for the shell b to be placed in. The air duct c is connected to the fixed frame unit 4 and the external fan.

[0037] In this embodiment, the positioning device is in use as follows: the standby brush unit 5 is installed on the garbage blocking frame unit 2 and is not connected to the torsion spring rotating plate unit 3. The two torsion spring rotating plate units 3 are pressed on the shell b, and the shell b is pressed on the fixed frame unit 4 to ensure the basic clamping and positioning effect. The air duct c is connected to the fixed frame unit 4 and the external fan to blow the assembled garbage a into the slotted bottom plate unit 1 to ensure the cleanliness of the operating environment on the upper surface of the slotted bottom plate unit 1.

[0038] In the above-described operating state, the vast majority of the assembly waste a is located between the two torsion spring rotating plate units 3 and can be collected by the air duct c. However, a small amount may accidentally be located outside the two torsion spring rotating plate units 3. In this case, the loosened standby brush unit 5 can sweep this outside assembly waste a into the slotted bottom plate unit 1, which is very clever and practical.

[0039] The slotted bottom plate unit 1 includes a flat plate 101 and a garbage receiving slot 102 provided on the upper surface of the flat plate 101 and located between the garbage blocking frame unit 2 and the fixed frame unit 4 .

[0040] In this embodiment, the assembly garbage a can be periodically removed from the garbage receiving groove 102 . The accumulated garbage in the garbage receiving groove 102 does not affect the cleanliness of the operating environment on the upper surface of the tablet 101 .

[0041] Among them, assembly waste a includes: tape, wires, protective film, packaging bags, etc.

[0042] The vertical cross-section of the garbage receiving chute 102 is in the shape of an inverted triangle.

[0043] In this embodiment, the garbage receiving chute 102 has at least one inclined bottom surface, which facilitates the upward sweeping of the internal garbage, which is impossible for ordinary garbage chutes in the shape of a rectangular parallelepiped.

[0044] The garbage blocking frame unit 2 includes a vertical side plate 201 provided on the upper surface of the flat plate 101 , and two end plates 202 provided on the vertical side plate 201 and located at both sides of the garbage receiving trough 102 .

[0045] In this embodiment, the long sides of the garbage collection trough 102 are aligned with the vertical side panels 201, and the wide sides are aligned with the end panels 202, ensuring that there is no transition plane between the garbage collection trough 102 and the garbage blocking rack unit 2. As soon as the assembled garbage a is blown onto the garbage blocking rack unit 2 by the wind, it will all fall into the garbage collection trough 102, ensuring efficient garbage collection.

[0046] The shape of the garbage blocking frame unit 2 is "U-shaped" and is used to properly hold the assembled garbage a to prevent it from being blown off to the outside of the flat plate 101.

[0047] The garbage blocking frame unit 2 further includes a mounting groove 203 provided on the upper surface of the end plate 202 and used for inserting the standby brush unit 5 .

[0048] In this embodiment, the brush body unit 5 in the standby state is always inserted into the mounting groove 203 , and an interference fit is formed between the two to prevent the brush body unit 5 in the standby state from falling off.

[0049] The torsion spring rotating plate unit 3 includes a vertical rod 301 arranged on the upper surface of the flat plate 101, a vertical perforated plate 302 sleeved on the vertical rod 301 and used to clamp the shell b, and a torsion spring 303 sleeved on the vertical rod 301 and located in the vertical perforated plate 302.

[0050] In this embodiment, the torsion direction of the torsion spring 303 is to approach the two vertical perforated plates 302 .

[0051] In addition, the vertical perforated plate 302 is rectangular in shape, and has a vertical hole therethrough for mounting the vertical rod 301. The lower surface of the vertical perforated plate 302 is pressed against the flat plate 101 to prevent the gap from leaking the assembly garbage a.

[0052] The torsion spring rotating plate unit 3 further includes a positioning groove 304 provided on the upper surface of the vertical perforated plate 302 and used for inserting the brush body unit 5 in the waiting position.

[0053] In this embodiment, the positioning groove 304 and the brush body unit 5 in the waiting position do not need to be interference-fitted, and it is sufficient to ensure that the latter can pull the vertical perforated plate 302 after being plugged into the former.

[0054] The fixing frame unit 4 includes a horizontal plate 401 arranged on the upper end surfaces of the two vertical rods 301, a vertical plate 402 arranged on the upper surface of the horizontal plate 401 and the flat plate 101, and a pipe hole 403 arranged on the vertical plate 402 and used to insert the air duct c.

[0055] In this embodiment, the height of the horizontal plate 401 is lower than the upper surface height of the shell b, and the vertical plate 402 is located between the two vertical rods 301, that is, facing the garbage collection groove 102, to ensure the efficiency of the blowing and collecting action of the assembled garbage a.

[0056] The fixing frame unit 4 further includes an elastic piece 404 provided on the horizontal plate 401 and used for clamping the housing b. There are two vertical plates 402 , which are respectively provided on both sides of the elastic piece 404 .

[0057] In this embodiment, the elastic sheet 404 is made of ordinary rubber, and the vertical perforated plate 302 is also provided with the ordinary rubber, ensuring that the three clamping positions of the shell b are all "soft" to prevent the shell b from being scratched or crushed.

[0058] In addition, the two air ducts c are located on both sides of the shell b, ensuring that the area where garbage is most likely to fall: between the shell b and the vertical perforated plate 302, can be directly blown, ensuring the directness and efficiency of the garbage collection action.

[0059] It should be noted that the air duct c cannot be opened when the shell b is assembled, because at this time the shell b and the vertical perforated plate 302 are completely against each other, blocking the front of the assembled garbage a, and the assembled garbage a cannot enter the garbage receiving trough 102.

[0060] The correct time to open the air duct c is: for example, after 2-3 assemblies, there is a lot of garbage between the two vertical perforated plates 302, and the vertical perforated plates 302 are first hooked to the standby state.

[0061] At this time, the vertical perforated plate 302 is also a "wind collecting hood" structure, which can ensure a small amount of short-term ventilation operation to blow all the garbage into the garbage collection trough 102, which is very clever.

[0062] The brush body unit 5 in the waiting position includes a lap plate 501 for twisting the torsion spring 303, two insertion columns 502 arranged at both ends of the lap plate 501 and respectively used to connect the end plate 202 and the vertical opening plate 302, and bristles 503 arranged on the lower surface of the lap plate 501 and located between the two insertion columns 502 and used to push the assembled garbage a into the garbage receiving groove 102.

[0063] In this embodiment, the material of the lap plate 501 is existing ordinary elastic rubber, which needs to be bent upward appropriately to allow the insertion column 502 to separate the positioning groove 304, thereby releasing the vertical perforated plate 302 and allowing the vertical perforated plate 302 to clamp the shell b.

[0064] In addition, the general shape of the lap plate 501 can also be "U-shaped", as shown in Figure 8. The advantages of this approach include:

[0065] First, the "U-shaped" structure itself can provide deformation, ensuring that the insertion column 502 is relatively easier to insert and remove from the positioning groove 304;

[0066] Second, the middle part of the "U-shaped" structure is concave, so that the relatively short bristles 503 can touch the flat plate 101. Otherwise, the bristles 503 can only be longer, and the disadvantage is that the longer bristles 503 cannot provide greater cleaning force.

[0067] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the aforementioned embodiments. Various modifications are possible within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. These modifications are non-inventive and are protected by patent law as long as they fall within the scope of the claims of the present invention.
