Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a battery sleeve rubber roller pressing device. Background Technology

[0002] In the lithium battery manufacturing process, a protective film needs to be applied to the top of the battery to cover it and improve battery safety. However, currently, the protective film is usually heat-fused to the battery cover first, and then the cover with the protective film is sealed onto the battery casing. The protective film extending from the cover is then applied to the surface of the casing by manual shaping. This manual shaping method has low production efficiency, high labor intensity, high staff turnover, and makes it difficult to guarantee the production quality of the protective film application.

A first elastic member is provided between the reinforcing block and the fixed base. The first elastic member always has a tendency to drive the reinforcing block away from the battery so that the pressure roller is pressed against the battery.

[0008] As a preferred embodiment of the battery sleeve adhesive roller pressing device, the roller pressing assembly further includes a limiting block. The limiting block includes a third connecting part and a limiting part arranged at an angle. The third connecting part is connected to the fixed seat. The limiting part and the fixed seat are spaced apart along the second direction to form a limiting groove. The first elastic member always has a tendency to drive the reinforcing block to press against the limiting groove and move away from the groove wall of the fixed seat.

[0010] As a preferred embodiment of the battery sleeve rubber roller pressing device, the battery sleeve rubber roller pressing device further includes a pushing assembly. At least one pushing assembly is respectively provided on both sides of the clamping assembly along the first direction. The pushing assembly includes a support block and a second elastic element.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figures 1 to 4As shown, the battery sleeve adhesive roller pressing device of this utility model includes a mounting base 1, a clamping assembly 2, and a roller pressing assembly 3. The clamping assembly 2 is disposed on the mounting base 1 and is used to clamp the housing 103 of the battery 100. Roller pressing assemblies 3 are respectively disposed on both sides of the clamping assembly 2 along a first direction (the first direction is the Y direction shown in the figure). The roller pressing assembly 3 includes a first driving member 31 and pressure rollers 32. At least two pressure rollers 32 in each roller pressing assembly 3 respectively abut against both sides of the top cover 101 of the battery 100 along a second direction (the second direction is the X direction shown in the figure). The first driving member 31 is disposed on the mounting base 1 and can be driven to connect with all the pressure rollers 32 in the roller pressing assembly 3. The first driving member 31 can drive the pressure rollers 32 to reciprocate in the vertical direction to roll the sleeve adhesive 102 of the top cover 101 along both sides of the second direction onto the housing 103 (the vertical direction is the Z direction shown in the figure). The first direction, the second direction, and the vertical direction are arranged at an angle to each other.

[0031] It is understandable that by setting roller pressing components 3 on both sides of the clamping assembly 2 along the first direction, and having at least two pressing rollers 32 in each roller pressing component 3 respectively abut against both sides of the top cover 101 along the second direction, the first driving member 31 drives the pressing rollers 32 to reciprocate in the vertical direction to press the adhesive 102 exposed on both sides of the top cover 101 along the second direction onto the housing 103. The bonding effect is good and the production efficiency is high. The driving of the first driving member 31 can effectively ensure the coordinated and consistent movement of the pressing rollers 32, ensure the bonding quality of the adhesive 102 and the housing 103, and improve the reliability and stability of the adhesive 102 bonding. By clamping the housing 103 with the clamping assembly 2, the position of the housing 103 is prevented from shifting during the bonding process of the adhesive 102, effectively ensuring the positional stability of the housing 103, thereby ensuring the bonding stability of the adhesive 102 and the housing 103.

[0032] It should be noted that the position of the clamping block 22 clamping the housing 103 should be higher than the highest point of the adhesive 102 after it is rolled and pasted onto the housing 103, so as to avoid the clamping block 22 being clamped onto the adhesive 102 during the clamping process of the housing 103, or the adhesive 102 being pasted onto the clamping block 22 during the rolling process of the adhesive 102.

[0033] In this embodiment, a roller pressing assembly 3 is provided at intervals on both sides of the clamping assembly 2 along the first direction. Each roller pressing assembly 3 includes a first driving member 31 and two pressure rollers 32 spaced apart on the first driving member 31 along the second direction. By ensuring that there is a pressure roller 32 at both ends of the adhesive tape 102 on both sides of the top cover 101 along the second direction to push and press it, the entire adhesive tape 102 can be pasted. Of course, in other embodiments, three, four or more roller pressing assemblies 3 can be provided at intervals along the first direction on the mounting base 1, or each roller pressing assembly 3 can be provided with two sets of pressure rollers spaced apart along the second direction, each set of pressure rollers including two, three or more pressure rollers 32. Specific examples are not listed here.

[0034] Furthermore, such as Figure 2 and Figure 4 As shown, the roller pressing assembly 3 also includes a fixed seat 33, a connecting block 34, and a first elastic member. The first driving member 31 includes two driving ends spaced apart along the second direction. Each driving end is provided with a fixed seat 33, and each fixed seat 33 is rotatably connected to a connecting block 34. The connecting block 34 includes a mounting part 341 and a first connecting part 342 and a second connecting part 343 arranged at an angle on the mounting part 341. The mounting part 341 is rotatably connected to the fixed seat 33. The pressure roller 32 is disposed on the first connecting part 342. A first elastic member is disposed between the second connecting part 343 and the fixed seat 33. The first elastic member always has a tendency to drive the second connecting part 343 away from the battery 100 so that the pressure roller 32 is pressed against the battery 100. The first driving member 31 can drive the two fixed seats 33 to move closer or further away from each other along the second direction so that the pressure roller 32 moves back and forth in the vertical direction.

[0035] For example, the first driving member 31 drives the two fixed seats 33 to move closer to each other in the second direction, so that the top cover 101 reacts and pushes the pressure roller 32, so that the pressure roller 32 overcomes the elastic force of the first elastic member and swings upward around the mounting part 341, thereby rolling the vest adhesive 102 onto the housing 103 in the vertical direction. The first driving member 31 drives the two fixed seats 33 to move away from each other in the second direction, so that the fixed seats 33 drive the connecting block away from the battery 100 in the second direction. The reaction force exerted by the battery 100 on the pressure roller 32 decreases, and the first elastic member drives the second connecting part 343 to move away from the battery 100, so that the first connecting part 342 swings downward around the mounting part 341, thereby rolling the vest adhesive 102 in the vertical direction. The movement of the fixed seats 33 driven by the first driving member 31 in the second direction is converted into the movement of the two pressure rollers 32 in the vertical direction. Each side of the pressure roller 32 requires an independent driving structure. This structure can reduce the number of driving members and is simple and compact. In addition, the first elastic element can also prevent the pressure roller 32 from rigidly contacting the top cover 101 or the housing 103, thereby preventing the extrusion of the vest adhesive 102 and effectively ensuring the product quality of the vest adhesive 102. The first elastic element can be directly adopted as a spring structure.

[0036] Specifically, the roller pressing assembly 3 also includes a reinforcing block 35. A connecting block 34 is rotatably connected to each side of the fixed base 33 along the first direction. The two ends of the pressure roller 32 along its length are respectively connected to the first connecting portions 342 on both sides of the fixed base 33 along the first direction. The reinforcing block 35 connects two second connecting portions 343 located on both sides of the fixed base 33 along the first direction. A first elastic element is provided between the reinforcing block 35 and the fixed base 33. The first elastic element always has a tendency to drive the reinforcing block 35 away from the battery 100, causing the pressure roller 32 to press against the battery 100. By using the first connecting portions 342 of the two connecting blocks 34 to connect the pressure roller 32, and using the reinforcing block 35 to connect the second connecting portions 343 of the two connecting blocks 34, the connection strength between the connecting blocks 34 and the pressure roller 32 is strengthened, ensuring the stability of the roller pressing effect of the pressure roller 32.

[0037] Furthermore, the fixed seat 33 is spaced apart from the battery 100 along the second direction. In the initial state of the rolling assembly 3, the pressure roller 32 just abuts against both sides of the top cover 101 along the second direction. Until the rolling is completed, the pressure roller 32 is still exposed on the side of the fixed seat 33 away from the first elastic member, so as to avoid the fixed seat 33 from colliding with the battery 100. Therefore, the rolling assembly 3 also includes a limiting block 36. The limiting block 36 includes a third connecting part 361 and a limiting part 362 arranged at an angle. The third connecting part 361 is connected to the fixed seat 33. The limiting part 362 and the fixed seat 33 are spaced apart along the second direction to form a limiting groove 363 for limiting the reinforcing block 35. The first elastic member always has the tendency to drive the reinforcing block 35 to press against the groove wall of the limiting groove 363 away from the fixed seat 33. By limiting the reinforcing block 35 with the limiting part 362, the reinforcing block 35 can still maintain its initial position even when the first elastic member is constantly pushing it. This ensures the position of the pressure roller 32 connected by the connecting block 34, so that when the battery 100 is clamped in the clamping assembly 2, the pressure roller 32 can just abut against the side of the top cover 101, improving the initial position accuracy of the pressure roller 32. This ensures that the subsequent pressure roller 32 can start rolling from the initial end of the adhesive 102 exposed on the top cover 101, ensuring the rolling effect of the adhesive 102.

[0038] Preferably, the pressure roller 32 is rotatably connected to the first connecting part 342. The rotational setting of the pressure roller 32 can effectively reduce the friction between the pressure roller 32 and the housing 103, thereby reducing the loss of the vest adhesive 102 during the rolling process and ensuring the product quality of the vest adhesive 102.

[0039] In some embodiments, such as Figure 1 As shown, the battery sleeve rubber roller pressing device also includes a drive mechanism 5. The drive mechanism 5 includes a second drive member 51. The mounting base 1 is disposed at the drive end of the second drive member 51. The second drive member 51 can drive the mounting base 1 to move in the vertical direction so that the clamping component 2 on the mounting base 1 can clamp the battery 100 above, thereby realizing the picking up of the battery 100.

[0040] Furthermore, the drive mechanism 5 also includes a rotary drive member 52, which is disposed at the drive end of the second drive member 51. The mounting base 1 is disposed at the drive end of the rotary drive member 52. The rotation axis of the rotary drive member 52 extends along a first direction, and the rotary drive member 52 can drive the mounting base 1 to rotate. In other words, the mounting base 1 has a mounting surface, and the clamping assembly 2 and the roller pressing assembly 3 are disposed on the mounting surface. In the initial state, the mounting surface of the rotary drive member 52 is facing upward. Under the drive of the second drive member 51, the clamping assembly 2 can clamp the battery 100 above. After the roller pressing assembly 3 completes the roller pressing of the adhesive 102, the rotating drive member 52 rotates the mounting surface downward, and the second drive member 51 drives the mounting base 1 to move downward and release the clamping block 22 to realize the unloading of the battery 100. The structure is simple and the operation is convenient.

[0041] The rotary drive component 52 can be one of a rotary cylinder, a rotary motor module, etc. The third drive component 21 and the first drive component 31 can be one of a linear cylinder, an electric cylinder, etc. In this embodiment, the second drive component 51 is driven by a linear motor module.

[0042] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the battery sleeve rubber roller pressing device also includes a pushing component 4. At least one pushing component 4 is respectively provided on both sides of the clamping component 2 along the first direction. The pushing component 4 includes a support block 41 and a second elastic member. The support block 41 is set on the mounting base 1 through the second elastic member. The battery 100 is placed on the support block 41. The second elastic member always has the tendency to drive the support block 41 to push the top cover 101 against the housing 103. It should be noted that in the initial state of the battery 100, the opening of the housing 103 faces downwards. The top cover 101 is pre-installed at the opening of the housing 103 after being welded to the core inside the housing 103. However, there is still a certain gap between the top cover 101 and the housing 103. Therefore, during the rolling of the sleeve adhesive 102, when the second driving member 51 drives the fixed seat 33 to rise, the second elastic member pushes the support block 41 so that the support block 41 can push the top cover 101 to be fully inserted into the housing 103, eliminating the gap between the top cover 101 and the housing 103. Moreover, the driving of the second elastic member can ensure the driving effect of the support block 41 while also providing a buffer, avoiding rigid contact between the support block 41 and the top cover 101 and causing damage to the top cover 101.

[0043] Furthermore, such as Figure 4As shown, the push assembly 4 also includes a guide shaft 42. A guide hole is provided on the mounting base 1. One end of the guide shaft 42 is connected to the support block 41, and the other end of the guide shaft 42 protrudes from the side of the mounting base 1 away from the support block 41. The guide shaft 42 is slidably connected to the guide hole. The second elastic element includes a spring, which is sleeved on the outer periphery of the guide shaft 42. In this embodiment, the cross-section of the guide shaft 42 is circular. Therefore, at least two guide shafts 42 are provided at the bottom of each support block 41 to prevent the support block 41 from rotating and to ensure the positional stability of the support block 41. The cooperation between the guide shaft 42 and the guide hole effectively improves the smoothness of the support block 41's vertical movement, ensuring the fitting accuracy between the top cover 101 and the housing 103. Furthermore, placing the spring outside the guide shaft 42 can guide the compression or extension of the spring, preventing the spring from bending and deforming in other directions and extending its service life.

[0044] Furthermore, a placement groove 411 is recessed on the support block 41, extending along the first direction and penetrating both sides of the support block 41 along the first direction. One end of the battery 100, with its top cover 101, is inserted into the placement groove 411. The placement groove 411 effectively improves the placement accuracy of the battery 100, thereby ensuring the accuracy of the subsequent rolling assembly 3 in rolling the adhesive 102. Optionally, the opening of the placement groove 411 gradually increases from the bottom to the top, using the inclined groove wall of the placement groove 411 to guide the battery 100, further improving the placement accuracy of the battery 100.

[0045] In other embodiments, the clamping assembly 2 includes a third driving member 21 and two clamping blocks 22. The third driving member 21 is mounted on the mounting base 1 and is pulsatorically connected to the two clamping blocks 22. The third driving member 21 can drive the two clamping blocks 22 to move closer or further apart to clamp or release the housing 103 of the battery 100. The automatic clamping of the housing 103 is achieved by using the first driving member 31 to move the two clamping blocks 22, resulting in a simple structure and convenient operation. Of course, in some embodiments, the clamping assembly 2 can also directly use readily available clamping structures such as grippers. Furthermore, the clamping assembly 2 can also include a buffer pad. A buffer pad is provided on the side of the clamping block 22 facing the housing 103. The buffer pad reduces the rigid contact between the clamping block 22 and the housing 103, thereby reducing wear and tear on both the clamping block 22 and the housing 103 and ensuring the product quality of the battery 100.

[0046] Furthermore, the battery adhesive roller pressing device also includes a sensor 6. At least one of the two clamping blocks 22 is equipped with the sensor 6, which detects whether the clamping block 22 is in close contact with the housing 103. Real-time detection by the sensor 6 is fed back to the controller to control the third drive component 21, ensuring that the clamping block 22 stably clamps the housing 103. This reduces the risk of unstable clamping affecting the adhesive 102's adhesion accuracy, or over-clamping causing damage to the housing 103, thus improving the safety of the housing 103's clamping and ensuring the product quality of the battery 100. For example, the sensor 6 is a photoelectric sensor, which includes a transmitter and a receiver. The transmitter and receiver are respectively disposed on the two clamping blocks 22 to detect the distance between the two clamping blocks 22, thereby confirming and adjusting the tightness of the contact between the clamping block 22 and the housing 103. Of course, the sensor 6 can also be other sensing elements such as a pressure sensor, which will not be elaborated upon here.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
