Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, specifically a glue-removing device. Background Technology

[0002] In the battery manufacturing process, adhesive pins need to be removed using a pin-removing device, for example, before the battery is dried. Traditionally, this device is equipped with a suction cup to pick up the adhesive pins and then pull them out. However, using a vacuum suction cup for pin removal is prone to failure due to weak and unstable suction force, significantly reducing production efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a nail removal device that can reduce the risk of nail removal failure and improve production efficiency in response to the above problems.

[0004] A device for removing adhesive nails, comprising:

[0005] Driver components;

[0006] A transfer mount is installed at the drive end of the drive assembly;

[0007] The pin removal assembly includes a clamping drive, a first clamp, and a second clamp. The clamping drive is mounted on the transfer seat. The first clamp and the second clamp are arranged opposite to each other and are mounted on the drive end of the clamping drive.

[0008] In some embodiments, the drive assembly is used to drive the transfer seat to move so that the transfer seat moves the pin removal assembly closer to or away from the battery.

[0009] In some embodiments, a clamping space for clamping the adhesive nail is formed between the first clamping member and the second clamping member, and the clamping drive member is used to drive the first clamping member and the second clamping member to move closer to or further away from each other.

[0010] In some embodiments, the pin-removing assembly further includes an intermediate clamping block disposed on the transfer seat and located between the first clamping member and the second clamping member.

[0011] In some embodiments, when the first clamping member moves close to the intermediate clamping block, it can squeeze the corresponding portion of the head of the glue nail to fold towards the intermediate clamping block, and when the second clamping block moves close to the intermediate clamping block, it can press the corresponding portion of the head of the glue nail to fold towards the intermediate clamping block.

[0012] In some embodiments, the adhesive nail removal device further includes a motion seat and a buffer elastic element. The motion seat is mounted on the drive end of the drive assembly, the transfer seat is movably connected to the motion seat, and the buffer elastic element abuts against the motion seat and the transfer seat along the moving direction of the transfer seat.

[0013] In some embodiments, the adhesive nail removal device further includes a sensing element, a first sensor, and a second sensor. The sensing element is mounted on the motion seat, and the first sensor and the second sensor are arranged along the path on which the sensing element moves as the motion seat moves.

[0014] In some embodiments, the pin-pulling assembly further includes a positioning element mounted on the transfer seat.

[0015] In some embodiments, two positioning elements are provided, with the first clamping element and the second clamping element both located between the two positioning elements.

[0016] In some embodiments, the positioning element has a positioning surface and at least two positioning protrusions protruding from the positioning surface.

[0017] In actual use, the aforementioned adhesive pin removal device places the battery to be removed below the pin removal assembly, with the adhesive pin to be removed located on the top surface of the battery. First, the drive assembly lowers the transfer seat, causing it to pull the pin removal assembly closer to the adhesive pin on the battery until the head of the pin enters between the first and second clamping members. Then, the clamping drive unit moves the first and second clamping members closer together, causing the two sides of the pin's head to fold upwards under the pressure of the first and second clamping members until they are clamped tightly. Next, the drive assembly raises the transfer seat, causing it to pull the pin removal assembly away from the battery. Because the first and second clamping members clamp the folded head of the pin, the pin can be pulled out of the injection hole as the pin removal assembly moves away from the battery.

[0018] Thus, in this embodiment, as the first and second clamping members approach each other, they respectively compress the two sides of the head of the adhesive nail, causing it to fold upwards and be clamped and fixed by the first and second clamping members. Then, under the driving action of the driving assembly, the first and second clamping members pull the adhesive nail upwards. Compared with the vacuum adsorption method used in the prior art, in this application, the first and second clamping members clamp the head of the adhesive nail in the folded state under the driving action of the clamping drive, which makes the fixation of the head of the adhesive nail more stable, greatly reducing the risk of nail removal failure, and thus helping to improve production efficiency.

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0029] It should be noted that the battery has an electrolyte injection hole on its top, although the injection hole can also be located on other sides of the battery; this is not a limitation. A rubber stud is used to plug this injection hole, thereby preventing electrolyte leakage from the battery and also preventing external dirt from entering the battery through the injection hole. The rubber stud includes an integrally formed head and a plugging part. The head is connected to one end of the plugging part, and the outer diameter of the head is larger than the outer diameter of the plugging part. When the rubber stud plugs the injection hole, the plugging part of the rubber stud is inserted into the injection hole, and the head of the rubber stud is located on the outer surface of the battery. During battery manufacturing, the rubber stud needs to be removed from the injection hole. Existing technology uses a suction cup to remove the rubber stud. However, the vacuum suction force generated by the suction cup is weak and unstable, easily leading to removal failures and significantly reducing production efficiency. To solve the above problems, it is necessary to provide a rubber stud removal device that greatly reduces the risk of removal failures and improves production efficiency.

[0030] Please see Figures 1 to 4This application provides a nail removal device, including a drive assembly 10, a transfer seat 20, and a nail removal assembly 30. The transfer seat 20 is mounted on the drive end of the drive assembly 10, enabling the drive assembly 10 to drive the transfer seat 20 to rise or fall. The nail removal assembly 30 includes a clamping drive member 31, a first clamping member 32, and a second clamping member 33. The clamping drive member 31 is mounted on the transfer seat 20, enabling the clamping drive member 31 to rise or fall together with the transfer seat 20. The first clamping member 32 and the second clamping member 33 are arranged opposite to each other, forming a clamping space B for clamping the nail between the first clamping member 32 and the second clamping member 33. The first clamping member 32 and the second clamping member 33 are mounted on the drive end of the clamping drive member 31, enabling the clamping drive member 31 to drive the first clamping member 32 and the second clamping member 33 to move closer or further apart.

[0031] In actual use, the battery to be removed is placed below the nail removal assembly 30, with the adhesive nail 100 to be removed located on the top surface of the battery. First, the drive assembly 10 drives the transfer seat 20 to descend, causing the transfer seat 20 to move the nail removal assembly 30 closer to the adhesive nail 100 on the battery until the head 102 of the adhesive nail 100 enters between the first clamping member 32 and the second clamping member 33. Then, the clamping drive assembly 31 drives the first clamping member 32 and the second clamping member 33 to move closer to each other, causing the two sides of the head 102 of the adhesive nail 100 to fold upward under the squeezing action of the first clamping member 32 and the second clamping member 33, until they are clamped tightly by the first clamping member 32 and the second clamping member 33. Then, the drive assembly 10 drives the transfer seat 20 to rise, causing the transfer seat 20 to move the nail removal assembly 30 away from the battery. Since the first clamping member 32 and the second clamping member 33 clamp the head 102 of the folded glue nail 100, the glue nail 100 can be pulled out from the injection hole as the nail removal assembly 30 moves away from the battery.

[0032] Thus, in this embodiment, as the first clamping member 32 and the second clamping member 33 approach each other, they respectively compress the two sides of the head 102 of the adhesive nail 100 and fold them upwards, thereby clamping and fixing them by the first clamping member 32 and the second clamping member 33. Then, under the driving action of the driving assembly 10, the first clamping member 32 and the second clamping member 33 pull the adhesive nail 100 upwards. Compared with the vacuum adsorption method used in the prior art, in this application, the first clamping member 32 and the second clamping member 33 clamp the head 102 of the adhesive nail 100 in the folded state under the driving action of the clamping driving member 31, which makes the fixation of the head 102 of the adhesive nail 100 more stable, greatly reducing the risk of nail removal failure, and thus helping to improve production efficiency.

[0033] It should be noted that the drive assembly 10 is not limited to driving the transfer seat 20 to rise or fall. In embodiments where the adhesive pin 100 is located on other sides of the battery, the drive assembly 10 is used to drive the transfer seat 20 to move in other directions, as long as it can move the pin removal assembly 30 closer to or away from the adhesive pin 100 on the battery, and to grip and remove the adhesive pin 100; no limitation is made here. For ease of understanding, this document uses the example of the adhesive pin 100 being located on the top surface of the battery, and the drive assembly 10 being used to drive the transfer seat 20 to rise or fall, for illustration.

[0034] It should also be noted that the drive assembly 10 can be a linear drive module such as a cylinder or electric cylinder, as long as it can drive the nail-pulling assembly 30 to move closer to or away from the battery; this is not limited here. The clamping drive component 31 can be a gripper cylinder, with the first gripper 32 and the second gripper 33 respectively mounted on the two drive ends of the gripper cylinder. Of course, the clamping drive component 31 is not limited to using a gripper cylinder; other drive components can also be used, such as using two linear cylinders to drive the first gripper 32 and the second gripper 33 respectively, as long as it can drive the first gripper 32 and the second gripper 33 to move closer to or away from each other; this is not limited here.

[0035] In the embodiments of this application, the nail removal assembly 30 further includes an intermediate clamping block 34. This intermediate clamping block 34 is disposed on the transfer seat 20 and located between the first clamping member 32 and the second clamping member 33. Thus, when it is necessary to remove the adhesive nail 100 from the battery, the transfer seat 20, driven by the drive assembly 10, lowers the nail removal assembly 30 until the intermediate clamping block 34 abuts against the head 102 of the adhesive nail 100. At this time, the portion of the head 102 of the adhesive nail 100 that abuts against the intermediate clamping block 34 is the first portion 1011, the portion of the head 102 of the adhesive nail 100 located between the intermediate clamping block 34 and the first clamping member 32 is the second portion 1013, and the portion of the head 102 of the adhesive nail 100 located between the intermediate clamping block 34 and the second clamping member 33 is the third portion 1015. Then, the clamping drive 31 drives the first clamping member 32 and the second clamping member 33 to move closer to each other, so that the first clamping member 32 squeezes the second part 1013 of the head 102, causing the second part 1013 of the head 102 to fold upward until it is clamped between the first clamping member 32 and the intermediate clamping block 34; at the same time, the second clamping member 33 squeezes the third part 1015 of the head 102, causing the third part 1015 of the head 102 to fold upward until it is clamped between the second clamping member 33 and the intermediate clamping block 34. Then, under the driving action of the drive assembly 10, the transfer seat 20 drives the nail pulling assembly 30 to rise, so that the first clamping member 32, the intermediate clamping block 34 and the second clamping member 33 together pull the glue nail 100 out of the battery's electrolyte filling hole.

[0036] It should be noted that the intermediate clamping block 34, together with the first clamping member 32 and the second clamping member 33, clamps and fixes the second part 1013 and the third part 1015 of the adhesive nail 100, which greatly increases the clamping area of ​​the head 102 of the adhesive nail 100, making the clamping of the adhesive nail 100 more stable, avoiding loosening during the nail removal process, and further reducing the risk of nail removal failure.

[0037] In a specific embodiment, the nail removal assembly 30 further includes a positioning member 35 mounted on the transfer seat 20. Further, the positioning member 35 has a positioning surface 351 facing the battery and at least two positioning protrusions 352 protruding from the positioning surface 351, thereby using the positioning protrusions 352 to abut against the battery or a clamp for holding the battery. Thus, under the driving action of the drive assembly 10, when the nail removal assembly 30 moves towards the battery until the intermediate clamping block 34 abuts against the head 102 of the adhesive nail 100, the positioning protrusions 352 on the positioning member 35 abut against the battery or the clamp for holding the battery, thereby achieving positioning of the nail removal assembly 30 and ensuring that the first clamping member 32 and the second clamping member 33 can more accurately clamp the head 102 of the adhesive nail 100.

[0038] Furthermore, the first clamping member 32, the intermediate clamping block 34, and the second clamping member 33 are arranged sequentially at intervals along a first preset direction, and the first clamping member 32 and the second clamping member 33 can move closer or further away along the first preset direction under the driving action of the clamping drive member 31. There are two positioning members 35, which are arranged at intervals along a second preset direction perpendicular to the first preset direction. The first clamping member 32, the intermediate clamping block 34, and the second clamping member 33 are all located between the two positioning members 35. Thus, using two positioning members 35 to simultaneously position the nail-pulling assembly 30 improves the positioning effect.

[0039] In embodiments of this application, the adhesive nail removal device further includes a moving seat 40 and a buffer elastic element 50. The moving seat 40 is mounted on the driving end of the driving assembly 10, enabling the driving assembly 10 to drive the moving seat 40 to rise or fall. A transfer seat 20 is movably connected to the moving seat 40, and the buffer elastic element 50 abuts against the moving seat 40 and the transfer seat 20 along the moving direction of the transfer seat 20. Optionally, the transfer seat 20 is movably connected to the moving seat 40 in a vertical direction, and the buffer elastic element 50 abuts against the moving seat 40 and the transfer seat 20 in a vertical direction. The buffer elastic element 50 provides a spring force that causes the transfer seat 20 to have a downward movement tendency. Thus, during the process of the driving assembly 10 driving the moving seat 40 to move downward, the moving seat 40 drives the transfer seat 20 and the nail removal assembly 30 to move downward until the intermediate clamping block 34 abuts against the head 102 of the adhesive nail 100. When the intermediate clamping block 34 abuts against the rubber nail 100, under the action of the pressure, the transfer seat 20 overcomes the elastic force of the buffer elastic element 50 and floats upward. That is, the buffer elastic element 50 plays a buffering role, avoiding hard impact between the intermediate clamping block 34 and the rubber nail 100 on the battery, thereby avoiding damage to the battery.

[0040] It should be noted that the buffer elastic element 50 can be a compression spring. Of course, in other embodiments, the buffer elastic element 50 can also be other specific elastic components, as long as they can play a buffering role, and there is no limitation here.

[0041] Furthermore, a fixing block 41 is fixedly mounted on the motion seat 40, which is located above the transfer seat 20. A buffer elastic member 50 abuts between the fixing block 41 and the top of the transfer seat 20, so that the buffer elastic member 50 can provide an elastic force that causes the transfer seat 20 to have a downward movement tendency.

[0042] Furthermore, a first guide rail 42 is provided on the motion seat 40, and a first slider 21 is provided on the transfer seat 20. The first slider 21 is slidably connected to the first guide rail 42. In this way, the movement of the first slider 21 along the first guide rail 42 guides the movement of the transfer seat 20 relative to the motion seat 40.

[0043] In a specific embodiment, the adhesive nail removal device further includes a mounting base 70, on which a moving seat 40 is movably connected. A drive assembly 10 is mounted on the mounting base 70, and the drive end of the drive assembly 10 is connected to the moving seat 40, thereby enabling the drive assembly 10 to drive the moving seat 40 to rise or fall relative to the mounting base 70.

[0044] Furthermore, a second guide rail is provided on the mounting base 70, and a second slider is provided on the moving base 40, the second slider being slidably connected to the second guide rail. In this way, the movement of the moving base 40 relative to the mounting base 70 is guided by the movement of the second slider along the second guide rail.

[0045] In a specific embodiment, the adhesive nail removal device further includes a sensing element 60, a first sensor 61, and a second sensor 62. The sensing element 60 is mounted on the motion seat 40, allowing it to move along with the motion seat 40. The first sensor 61 and the second sensor 62 are mounted on the mounting base 70 and positioned along the movement path of the sensing element 60 as it moves with the motion seat 40. Thus, by using the first sensor 61 and the second sensor 62 to detect the position of the sensing element 60, the movement of the sensing element 60 between the first sensor 61 and the second sensor 62 is controlled, thereby controlling the movement of the motion seat 40 between its upper and lower limit positions and preventing the motion seat 40 from exceeding a preset travel range.

[0046] In one embodiment, the first sensor 61 is located above the second sensor 62. When the first sensor 61 detects the sensing element 60 (i.e., when the sensing element 60 moves upward to the position of the first sensor 61), it indicates that the moving seat 40 has risen to its upper limit position, at which point the drive assembly 10 stops driving the moving seat 40 to continue rising. When the second sensor 62 detects the sensing element 60 (i.e., when the sensing element 60 moves downward to the position of the second sensor 62), it indicates that the moving seat 40 has descended to its lower limit position, at which point the drive assembly 10 stops driving the moving seat 40 to continue descending. Thus, the movement of the moving seat 40 between its upper and lower limit positions is controlled through the cooperation of the first sensor 61, the second sensor 62, and the sensing element 60, greatly improving the safety of the device.

[0047] It should be noted that the first sensor 61 and the second sensor 62 can be contact sensors or non-contact sensors, as long as they can detect the passing sensing element 60. No limitation is made here.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
