Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, specifically relating to an adhesive applicator that allows for quick replacement of pre-applied adhesive. Background Technology

[0002] With the increasing popularity and development of electric vehicles, the market demand for lithium-ion batteries is also constantly increasing. To meet this growing market demand, improving the production efficiency of lithium batteries has become a top priority. Currently, lithium battery production is gradually becoming more automated, but due to limitations in equipment technology, some production processes are difficult to complete through automated equipment. Therefore, these production operations still require manual labor. For example, in the battery adhesive application process, when the adhesive tape in the pre-filled assembly runs out, it is necessary to manually replace the empty pre-filled assembly with a fully filled one.

[0003] Existing technologies employ a detachable connection between the adhesive preparation component and the adhesive application component to facilitate the replacement of the adhesive preparation component. For example, positioning holes are provided on both components, and the detachable connection is achieved through the engagement of these holes and pins; alternatively, a clamp is used to achieve a detachable connection. While these detachable connection structures allow for the replacement of the adhesive preparation component, the connection stability is poor, easily leading to displacement or even detachment of the component during the adhesive application process, which is detrimental to the normal and stable execution of the adhesive application operation.

[0012] As a further description of the technical solution of this utility model, the glue preparation unit also includes a glue roll roller for rotating and releasing the glue roll, a conveying roller for conveying the glue roll, and a glue pulling roller for tightening the glue roll.

[0013] Both the film roll and the conveying roll are fixedly connected to the second mounting frame, and the film pulling roll is movably connected to the second mounting frame.

[0014] As a further description of the technical solution of this utility model, the second mounting frame is provided with a sliding rail, a sliding plate is slidably connected on the sliding rail, the sliding plate is connected to the rubber-pulling roller, and the first mounting frame is provided with a rubber-pulling component for limiting the sliding of the sliding plate.

The driving direction of the second driving member is the same as the sliding direction of the slide plate, and the adhesive-pulling pressure block abuts against the slide plate.

[0016] As a further description of the technical solution of this utility model, the second mounting bracket is provided with a lifting handle.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] refer to Figures 1 to 2 The adhesive application mechanism with quick-change pre-filled adhesive provided in this embodiment includes an adhesive application unit 1 and a pre-filled adhesive unit 2 for providing adhesive tape to the adhesive application unit 1. The pre-filled adhesive unit 2 is detachably connected to the adhesive application unit 1. It should be noted that there are at least two sets of pre-filled adhesive units 2, so that fully loaded pre-filled ...

[0036] Specifically, the adhesive application unit 1 includes a first mounting bracket 11, and the adhesive preparation unit 2 includes a second mounting bracket 21. The first mounting bracket 11 and the second mounting bracket 21 are connected by a first fixing component 3 and a second fixing component 4. The first fixing component 3 is used to limit and fix the second mounting bracket 21 in a first direction, and the second fixing component 4 is used to limit and fix the second mounting bracket 21 in a second direction. The first direction and the second direction are opposite.

[0037] In this embodiment, the first direction is vertically downward and the second direction is vertically upward. It can be understood that the first fixing component 3 limits the second mounting bracket 21 in the vertically downward direction, restricting its downward movement. Combined with the second fixing component 4 limiting the second mounting bracket 21 in the vertically upward direction, its upward movement is also restricted. The relative position between the first mounting bracket 11 and the second mounting bracket 21 is better restricted and fixed, thus preventing the glue preparation unit 2 from shifting position during the glue application process. The connection between the glue application unit 1 and the glue preparation unit 2 is firm and stable, which is beneficial for the normal and stable operation of the glue application process.

[0038] In some embodiments, the first fixing component 3 includes a first fixing member 31 disposed on the first mounting bracket 11 and a second fixing member 32 disposed on the second mounting bracket 21, wherein the second fixing member 32 is engaged with the first fixing member 31 along a first direction. In some embodiments, the first fixing member 31 and the second fixing member 32 may be a slot and a block, or a block and a slot, or a hole and a hook, or a hook and a hole, etc.

[0039] In this embodiment, the first fixing member 31 is a slot, and the second fixing member 32 is a block. Specifically, the slot extends from the mounting surface of the first mounting bracket 11 toward the second mounting bracket 21, with the opening of the slot facing upwards. The block protrudes downwards from the lower edge of the second mounting bracket 21, and the block engages or disengages from the slot by moving vertically. During installation, the second mounting bracket 21 is held close to the first mounting bracket 11 and moved along the first direction, causing the lower surface of the block to abut against the bottom wall of the slot, thus engaging the block within the slot. The movement of the second mounting bracket 21 along the first direction is restricted, and the second mounting bracket 21 is initially fixed to the first mounting bracket 11. During disassembly, the second mounting bracket 21 is held and moved along the second direction, causing the block to disengage from the slot, completing the disassembly of the adhesive preparation unit 2. The installation and disassembly process is simple, convenient, and easy to operate, enabling rapid replacement of the adhesive preparation unit 2. This effectively shortens the downtime of the adhesive application mechanism, which helps improve the operational efficiency of battery production and thus meets the production needs of high efficiency and high profitability.

[0040] As a further optimization, the number of slots and blocks is set to two. Both slots are located on the mounting surface of the first mounting bracket 11 and are distributed left-right. Each block engages with one slot. In some embodiments, the two slots can be symmetrically distributed left-right or asymmetrically distributed left-right. In this embodiment, the two slots are asymmetrically distributed left-right. The connection between the first mounting bracket 11 and the second mounting bracket 21 is achieved by the engagement and cooperation of the two blocks with the two slots, which improves the connection stability between the adhesive application unit 1 and the adhesive preparation unit 2, thereby ensuring the normal and stable operation of the adhesive application mechanism and improving the stability of battery production operations.

[0041] In some embodiments, the second fixing component 4 includes a first driving member 41 disposed on the first mounting bracket 11 and a fixing block 42 connected to the driving end of the first driving member 41. The first driving member 41 drives the fixing block 42 to abut against the second mounting bracket 21 in a first direction, thereby restricting the movement of the second mounting bracket 21 in a second direction. As one embodiment, the first driving member 41 is a driving cylinder that can drive the fixing block 42 to extend in the first direction or retract in the second direction. When the fixing block 42 extends in the first direction, it abuts against the second mounting bracket 21, and the movement of the second mounting bracket 21 in the second direction is restricted, thereby achieving secondary limiting and fixing of the second mounting bracket 21; when the fixing block 42 retracts in the second direction, the restriction on the second mounting bracket 21 can be released, thereby facilitating the removal of the glue preparation unit 2.

[0042] With the cooperation of the first fixing component 3 and the second fixing component 4, the glue preparation unit 2 is limited and fixed in both the first and second directions. The connection between the glue application unit 1 and the glue preparation unit 2 is strong. Moreover, the structure of the first fixing component 3 and the second fixing component 4 is simple, and the installation and disassembly process is convenient and efficient, which is conducive to the rapid replacement of the glue preparation unit 2.

[0043] The specific implementation process of this embodiment is as follows: When the film roll of the glue preparation unit 2 is used up, the first driving member 41 can be retracted by the external point control switch. The fixing block 42 moves away from the second mounting frame 21 in the second direction under the drive of the first driving member 41, releasing the second mounting frame 21 from the limit in the second direction. Hold the second mounting frame 21 and move it in the second direction to make the card block disengage from the card slot and remove the empty glue preparation unit 2. Then hold the pre-prepared full glue preparation unit 2 and bring it close to the first mounting frame 11 and move it in the first direction to make the card block engage in the card slot. The first driving member 41 is extended by the external point control switch. The fixing block 42 moves in the first direction and abuts the second mounting frame 21 under the drive of the first driving member 41 to complete the replacement of the glue preparation unit 2.

[0044] The adhesive application mechanism of this embodiment, which allows for quick replacement of the prepared adhesive, ensures that the relative positions of the first and second mounting brackets do not shift through the cooperation of the first and second fixing components. This improves the connection stability between the adhesive application unit and the prepared adhesive unit, and facilitates stable operation of the adhesive application process. The cooperation of the first and second fixing components enables initial fixation of the second mounting bracket, resulting in a simple connection structure that is easy to install and disassemble. The first driving component drives the fixing block to abut against the second mounting bracket, achieving secondary fixation of the second mounting bracket. This further enhances the connection stability between the first and second mounting brackets, and the structure is simple and easy to install.

[0045] Example 2

[0046] As a further optimization of Example 1, refer to Figures 3 to 5 The adhesive preparation unit 2 also includes a roll roller 22 for rotating and releasing the tape roll, a conveyor roller 23 for conveying the tape, and a tensioning roller 24 for tightening the tape. The roll roller 22 and the conveyor roller 23 are both fixedly connected to the second mounting frame 21, while the tensioning roller 24 is movably connected to the second mounting frame 21. By restricting the movement of the tensioning roller 24, the tape can be tightened to keep it taut, facilitating tape cutting and ensuring the quality of tape application.

[0047] In some embodiments, the number of conveyor rollers 23 can be one or more, and the number of adhesive-pulling rollers 24 can also be one or more. In this embodiment, there are three conveyor rollers 23 and one adhesive-pulling roller 24. The tape is fed out from the tape roll roller 22, then passes around two conveyor rollers 23, then around the adhesive-pulling roller 24, and finally passes around one conveyor roller 23 before extending to the adhesive application station.

[0048] In some embodiments, in order to improve the stability of the tape conveying in the glue preparation unit 2, a damper can be installed on the glue roll 22. The damper can slow down and control the glue release speed of the glue roll 22 to maintain the smoothness of the tape conveying, thereby ensuring the normal and stable operation of the adhesive application mechanism and guaranteeing the adhesive application quality.

[0049] The movable connection between the adhesive-applying roller and the second mounting frame can be achieved through various connection structures. As one implementation, the second mounting frame 21 has a vertically oriented sliding rail 25, on which a sliding plate 26 is slidably connected. The sliding plate 26 can move vertically up and down on the sliding rail 25. The sliding plate 26 is connected to the adhesive-applying roller 24. The first mounting frame 11 has an adhesive-applying assembly 12 for limiting the sliding of the sliding plate 26. The adhesive-applying assembly 12 includes a second driving member 121 mounted on the first mounting frame 11 and an adhesive-applying pressure block 122 connected to the driving end of the second driving member 121. The driving direction of the second driving member 121 is the same as the sliding direction of the sliding plate 26, and the adhesive-applying pressure block 122 abuts against the sliding plate 26. In this embodiment, the second driving member 121 is a driving cylinder that can drive the adhesive-applying pressure block 122 to extend or retract.

[0050] It is understood that both ends of the sliding track 25 are equipped with limiting structures. The second driving member 121 drives the adhesive-pulling block 122 to move, causing the adhesive-pulling block 122 to push the slide plate 26 against the limiting structure, thereby restricting the movement of the slide plate 26. This allows the adhesive-pulling roller 24 to restrain the adhesive tape to achieve a taut state. In this embodiment, when the adhesive preparation unit 2 is connected to the adhesive application unit 1, the slide plate 26 is located below the adhesive-pulling block 122. The second driving member 121 drives the adhesive-pulling block 122 to retract downwards, causing the adhesive-pulling block 122 to push the slide plate 26 against the limiting structure of the sliding track 25, thus realizing the adhesive-pulling action. When the adhesive tape of the adhesive preparation unit 2 is used up, a sensor can send a signal to the second driving member 121, causing the second driving member 121 to drive the adhesive-pulling block 122 to extend upwards, thereby releasing the restriction on the slide plate 26, so as to facilitate the replacement of the adhesive preparation unit 2.

[0051] In addition, since the adhesive pulling action of the adhesive pulling assembly 12 can also limit and fix the second mounting bracket 21, the adhesive pulling assembly 12 can further improve the connection stability between the adhesive application unit 1 and the adhesive preparation unit 2.

[0052] Example 3

[0053] As a further optimization of Example 2, refer to Figure 6 In order to reduce the difficulty of operation and improve the efficiency of operation when replacing the glue preparation unit 2, a lifting handle 27 can be set on the second mounting bracket 21 to facilitate hand operation by the operator, which is conducive to improving the production efficiency of the operation.

[0054] To further reduce operational difficulty, a cutout 211 can be provided on the second mounting bracket 21 to reduce its weight, thereby improving ease of operation when replacing the adhesive preparation unit 2 and increasing work efficiency. In some embodiments, the weight of the second mounting bracket 21 can be further reduced by decreasing its thickness, further improving operational convenience.

[0055] The tape application unit 1 also includes a tape pressing assembly 13 for pressing the tape and a tape cutting assembly 14 for cutting the tape. By pressing and fixing the tape with the tape pressing assembly 13, slippage of the tape can be prevented, thereby ensuring the accuracy of the tape cutting operation and guaranteeing the tape application quality.
