[0029] The adhesive application device and battery cell processing equipment provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0030] In existing technologies, when applying adhesive to battery cells using an adhesive applicator, a suction cup is typically used to adhere the adhesive tape. After the adhesive tape is adhered to the suction cup, it is fixed on the suction cup, making it impossible to adjust the relative position of the adhesive tape and the battery cell. Furthermore, because the adhesive tape cannot be accurately adhered to the preset position on the suction cup during the adsorption process, errors occur in the relative position of the adhesive tape and the battery cell. This results in incomplete adhesive application and failure to meet the application requirements.

[0031] Optionally, such as Figure 1 As shown in the figure, this application embodiment proposes an adhesive applicator for applying adhesive tape to battery cells, comprising: a driving component 1, an adhesive applicator 2, and a mounting base assembly 3; the driving component 1 is connected to the mounting base assembly 3, the mounting base assembly 3 is fixedly connected to the adhesive applicator 2, and the adhesive applicator 2 has an adhesive surface on the side opposite to the mounting base assembly 3, the adhesive surface being used to fix the adhesive tape; the driving component 1 is used to drive the mounting base assembly 3 to rotate, thereby driving the adhesive applicator 2 to rotate, so as to adjust the position of the adhesive tape.

[0032] In the embodiments of this application, the driving component 1 is connected to the mounting base assembly 3, and the mounting base assembly 3 is fixedly connected to the adhesive application assembly 2. The adhesive application assembly 2 has an adhesive surface on the side opposite to the mounting base assembly 3, which is used to fix the adhesive paper. In this way, the driving component 1 can drive the mounting base assembly 3 to rotate, thereby causing the adhesive application assembly 2 to rotate, so as to adjust the relative position of the adhesive paper and the battery cell, thereby meeting the requirements for adhesive application to the battery cell.

[0033] It should be noted that the adhesive application device of this application can be used in fields such as adhesive application of battery cell tabs, adhesive application of battery cell appearance, and adhesive application of various hardware products. The embodiments of this application are not limited here.

[0034] In some embodiments, such as Figure 1 As shown, the drive component 1 can be configured as a direct drive motor, which includes a cylindrical housing and a turntable. The mounting base assembly 3 is mounted on the turntable. A stator unit is embedded in the housing, and a rotor unit is embedded in the turntable. In this way, the stator unit in the housing can drive the rotor unit to rotate, thereby driving the mounting base assembly 3 to rotate. Of course, the drive component 1 can also be configured as a cylinder, motor, or other drive components.

[0035] Furthermore, direct drive motors offer advantages such as low speed and high torque, high-precision positioning, high response speed, simple structure, reduced mechanical losses, and low noise. Therefore, using a direct drive motor to adjust the relative position of the adhesive tape and the battery cell facilitates high-precision adjustment.

[0036] Optionally, such as Figure 1 and Figure 2 As shown, the mounting bracket assembly 3 includes a first mounting member 31 and a second mounting member 32; the first mounting member 31 is fixedly connected to the adhesive application assembly 2, and the second mounting member 32 is fixedly connected to the drive member 1. The first mounting member 31 and the second mounting member 32 are telescopically connected along the rotation axis direction of the drive member 1.

[0037] In the field of battery cell tab bonding, existing bonding devices directly apply the adhesive paper to the battery cell tab after picking it up. After the adhesive paper contacts the tab, it is necessary to continue pushing the adhesive paper to ensure a tight bond between the adhesive paper and the tab. However, the bonding method of existing devices can cause the tab to bend, crack, or even break off the tab, resulting in damage to the battery cell.

[0038] It should be noted that the rotation direction of the drive component 1 is the first direction Z, the second direction Y is perpendicular to the first direction Z, and the third direction X is perpendicular to the first direction Z and the second direction Y respectively.

[0039] In this embodiment, the first mounting member 31 is fixedly connected to the adhesive application assembly 2, and the second mounting member 32 is connected to the driving member 1. The first mounting member 31 and the second mounting member 32 are telescopically connected along the rotation axis of the driving member 1. Thus, when the adhesive tape contacts the tab, as the adhesive application assembly 2 continues to move, the tab exerts a reaction force on the adhesive application assembly 2, causing the adhesive application assembly 2 to retract relative to the second mounting member 32 under the action of the reaction force. This avoids hard contact between the adhesive application assembly 2 and the tab, preventing damage to the tab or even the tab being pried off the battery.

[0040] Optionally, such as Figure 1 and Figure 3 As shown, the mounting base assembly 3 also includes an elastic element 33; along the rotation axis direction of the drive member 1, the first mounting member 31 and the second mounting member 32 are slidably connected, and the elastic element 33 is disposed between the first mounting member 31 and the second mounting member 32, and the elastic element 33 is used to provide cushioning for the first mounting member 31.

[0041] In this embodiment, the first mounting member 31 and the second mounting member 32 are slidably connected along the rotation axis of the drive member 1, and the elastic member 33 is disposed between the first mounting member 31 and the second mounting member 32. Thus, when the adhesive assembly 2 contacts the battery cell, the elastic member 33 is compressed, thereby providing a buffer for the first mounting member 31 and protecting the battery cell. Furthermore, by providing the elastic member 33, the problem of excessive force on the drive member 1 in the first direction Z, which could cause damage to the drive member 1, can be avoided.

[0042] In some embodiments, such as Figure 3 and Figure 4 As shown, the first mounting member 31 has a first mounting hole, and the second mounting member 32 has a second mounting hole. An elastic member 33 is disposed in both the first and second mounting holes, with one end connected to the first mounting member 31 and the other end connected to the second mounting member 32. This allows the elastic member 33 to deform along the axial direction of the first and second mounting holes, ensuring relative movement between the first and second mounting members 31 and 32 along the axial direction of the first mounting hole and preventing deviation.

[0043] In some embodiments, the elastic element 33 can be configured as a compression spring, and multiple compression springs can be configured; specifically, multiple compression springs are spaced apart on the first mounting member 31. This ensures that the first mounting member 31 is subjected to uniform force, thereby providing uniform force to the adhesive application assembly 2 after it contacts the battery cell. Furthermore, elastic elements such as elastic rubber can also be used to provide cushioning for the first mounting member 31, and this embodiment of the application does not limit this application.

[0044] Optionally, such as Figure 4As shown, it also includes a slider 34; the slider 34 is mounted on the second mounting member 32, and the first mounting member 31 is connected to the slider 34. The first mounting member 31 can slide relative to the second mounting member 32 through the slider 34.

[0045] In this embodiment, by mounting the slider 34 on the second mounting member 32 and connecting the first mounting member 31 to the slider 34, the first mounting member 31 can slide relative to the second mounting member 32 via the slider 34. This allows the first mounting member 31 and the second mounting member 32 to slide along the sliding direction of the sliding structure when they move relative to each other, preventing the first mounting member 31 from wobbling or becoming misaligned during sliding.

[0046] In some embodiments, such as Figure 4 As shown, the slide rail mechanism can be configured as a cross roller guide rail; the slide rail mechanism includes a first guide rail 341, a second guide rail 342, rollers, and a roller retainer 343; the first guide rail 341 is disposed on a first mounting member 31, and the second guide rail 342 is disposed on a second mounting member 32. A mounting groove is formed between the first guide rail 341 and the second guide rail 342, and the roller retainer 343 is disposed in the mounting groove, filled with rollers. The first guide rail 341 can slide relative to the rollers. This allows the first mounting member 31 to achieve high-precision displacement. Alternatively, the slide rail mechanism can also be a combination of a slider and a slide rail; this embodiment of the application does not impose any limitations on this.

[0047] In some embodiments, such as Figure 1 As shown, the slide rail mechanism can be set into two sets, with the two sets of slide rail mechanisms arranged parallel to each other along the first direction Z, so as to ensure high synchronization on both sides of the first mounting member 31, and at the same time, to ensure smooth operation of the first mounting member 31, thereby improving the movement accuracy and efficiency of the first mounting member 31.

[0048] Optionally, such as Figure 1 and Figure 4 As shown, the first mounting member 31 has a sliding space 4 on the side away from the adhesive assembly 2, and the second mounting member 32 is at least partially located in the sliding space 4 at the end away from the drive member 1, and is telescopically connected to the first mounting member 31.

[0049] In this embodiment, a sliding space 4 is provided on the side of the first mounting member 31 away from the adhesive application assembly 2, and at least part of the end of the second mounting member 32 away from the driving member 1 is disposed within the sliding space 4 and is retractably connected to the first mounting member 31. This allows the end of the second mounting member 32 away from the driving member 1 to be disposed within the sliding space 4, thereby reducing the size of the adhesive application device along the first direction Z and minimizing the space occupied.

[0050] In some embodiments, the first mounting member 31 includes a first mounting portion and two second mounting portions; the first mounting portion is fixedly connected to the adhesive assembly 2, the two second mounting portions are disposed on opposite sides of the first mounting portion along the second direction Y, a sliding space 4 is formed between the two second mounting portions and the first mounting portion, and the second mounting member 32 is disposed within the sliding space 4.

[0051] In some embodiments, the second mounting member 32 includes a third mounting portion and two fourth mounting portions; the third mounting portion is fixedly connected to the driving member 1, and the two fourth mounting portions are disposed on opposite sides of the third mounting portion along the second direction Y, with the two fourth mounting portions corresponding one-to-one with the two second mounting portions; the slide rail mechanism is disposed between the second mounting portion and the fourth mounting portion.

[0052] Optionally, such as Figure 2 As shown, the first mounting component 31 is provided with a limiting block 6, and the second mounting component 32 is provided with a limiting groove 7. The limiting block 6 extends at least partially into the limiting groove 7 and slides within the limiting groove 7. The limiting block 6 cooperates with the limiting groove 7 to limit the movement of the first mounting component 31 relative to the second mounting component 32.

[0053] In this embodiment, a limiting block 6 is provided in the first mounting member 31, and a limiting groove 7 is provided in the second mounting member 32. The limiting block 6 extends at least partially into the limiting groove 7 and slides within the limiting groove 7. The limiting block 6 cooperates with the limiting groove 7 to limit the movement of the first mounting member 31 relative to the second mounting member 32. This avoids excessive displacement of the first mounting member 31 relative to the second mounting member 32, thereby limiting the compression length of the elastic member 33 and improving its service life.

[0054] Specifically, such as Figure 2 As shown, without the cooperation of the limiting block 6 and the limiting groove 7, the first mounting member 31 will slide excessively along the first direction Z toward the side away from the second mounting member 32, causing the elastic member 33 to dislodge from the first mounting hole and resulting in the failure of the adhesive applicator. Furthermore, without the cooperation of the limiting block 6 and the limiting groove 7, after the adhesive applicator 2 contacts the battery cell, the first mounting member 31 can also slide along the first direction Z toward the side closer to the second mounting member 32. This will cause the elastic member 33 to be over-compressed, thereby reducing the service life of the elastic member 33.

[0055] Optionally, such as Figure 3 As shown, the adhesive application assembly 2 includes an adsorption plate 21; the adsorption plate 21 is fixedly connected to the first mounting component 31, and the side of the adsorption plate 21 facing away from the first mounting component 31 is provided with a plurality of adsorption holes, which are respectively adapted to connect to an external negative pressure mechanism.

[0056] In this embodiment, the adsorption plate 21 is fixedly connected to the first mounting member 31. The adsorption plate 21 has a plurality of adsorption holes, which are adapted to connect to an external negative pressure mechanism. In this way, the negative pressure mechanism provides negative pressure to the adsorption holes, so as to adsorb the adhesive paper through the adsorption holes and make the adhesive paper fixed and not easy to fall off.

[0057] Optionally, such as Figure 3 As shown, the adhesive application assembly 2 also includes a sealing element 22; the sealing element 22 is disposed between the adsorption plate 21 and the first mounting element 31, and is used to seal the gap between the adsorption plate 21 and the first mounting element 31.

[0058] In this embodiment, the sealing member 22 is disposed between the adsorption plate 21 and the first mounting member 31. This allows the sealing member 22 to seal the gap between the adsorption plate 21 and the first mounting member 31, thereby ensuring the airtightness of the negative pressure chamber 23.

[0059] Optionally, such as Figure 3 As shown, the adsorption plate 21 and the first mounting member 31 enclose a negative pressure cavity 23, which is connected to a plurality of adsorption holes; the negative pressure cavity 23 is adapted to be connected to an external negative pressure mechanism to provide negative pressure to the plurality of adsorption holes.

[0060] In this embodiment, a negative pressure cavity 23 is formed by enclosing the adsorption plate 21 and the first mounting member 31. The negative pressure cavity 23 is connected to a plurality of adsorption holes. The negative pressure cavity 23 is connected to an external negative pressure mechanism to provide negative pressure to the plurality of adsorption holes. In this way, the negative pressure of the adsorption holes can be balanced by using the negative pressure cavity 23, thereby making the adsorption force of the plurality of adsorption holes more uniform and stable.

[0061] Optionally, such as Figure 3 As shown, it also includes a connecting pipe 8; one end of the connecting pipe 8 is connected to the negative pressure chamber 23, and the other end of the connecting pipe 8 is used to connect to an external negative pressure mechanism.

[0062] In this embodiment, one end of the connecting pipe 8 is connected to the negative pressure chamber 23, and the other end of the connecting pipe 8 is connected to the external negative pressure mechanism. This facilitates the connection between the negative pressure chamber 23 and the external negative pressure mechanism via the connecting pipe 8, allowing the external negative pressure mechanism to provide negative pressure to the negative pressure chamber 23 through the connecting pipe 8.

[0063] Optionally, this application provides a battery cell processing device, including a battery cell fixing device and an adhesive applicator as described in the above embodiments; the battery cell fixing device and the adhesive applicator are arranged opposite to each other, the battery cell fixing device is used to fix the battery cell, and the adhesive applicator is used to apply adhesive tape to the battery cell.

[0064] In the embodiments of this application, by connecting the driving component 1 to the mounting base assembly 3, and fixing the mounting base assembly 3 to the adhesive application component 2, the adhesive application component 2 has an adhesive surface on the side opposite to the mounting base assembly 3, which is used to fix the adhesive tape. In this way, the driving component 1 can drive the mounting base assembly 3 to rotate, thereby driving the adhesive application component 2 to rotate, thereby improving the adhesion accuracy of the adhesive tape on the battery cell and thus improving the quality of the battery cell product.

[0065] In some embodiments, the cell processing equipment further includes a CCD camera and a controller. The CCD camera and the drive unit 1 are electrically connected to the controller. After the CCD camera takes a picture of the adhesive tape, it transmits the data to the controller. The controller controls the direct drive motor to rotate according to the data from the CCD camera, thereby adjusting the relative position of the adhesive tape and the cell.

[0066] In some embodiments, such as Figure 1 As shown, the adhesive applicator also includes a fixed base 5, and a drive component is mounted on the fixed base 5. The battery cell processing equipment also includes a moving mechanism, with the fixed base 5 mounted on the moving mechanism. The moving mechanism includes a horizontal moving component and a lifting component. The horizontal moving component can move the adhesive applicator along the second direction Y and the third direction X. The lifting component can move the adhesive applicator along the first direction Z to move it closer to or further away from the battery cell.
