Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery cell gluing, and particularly to a gluing device. BACKGROUND

[0002] In the manufacture of square battery cells, double-sided adhesive tape is usually pasted on the side walls of the battery cells to achieve stable connection between adjacent battery cells. However, the existing gluing device only has the ability to move in the horizontal and vertical directions, and cannot directly perform gluing operation on the side walls of the battery cells in the vertical posture. Therefore, in actual production, the battery cells originally in the vertical state have to be first flipped to the horizontal state, and then the gluing operation is performed. The gluing process is as follows: the gluing head adsorbs the double-sided adhesive tape through vertical movement, then moves horizontally to above the battery cell placed in the horizontal state, and again adsorbs the adhesive tape to the upper surface of the battery cell (which is the side wall in the original vertical state of the battery cell) through downward movement. After the gluing is completed, the battery cell needs to be flipped back to the vertical state again to meet the arrangement requirements of the subsequent process. This process not only increases the steps of processing the battery cell, reduces the overall production efficiency, but also increases the complexity and manufacturing cost of the equipment.

[0033] like Figures 1 to 5 As shown, in this embodiment, a gluing device is used to glue a battery cell 800, and the battery cell 800 has a gluing surface 810 perpendicular to a horizontal plane. The gluing device includes:

[0034] The adhesive supply assembly 100 includes a horizontally arranged adhesive supply table 110 for placing adhesive tape;

[0035] The adhesive tape assembly includes an adsorption head 200 for adsorbing the adhesive tape;

[0036] The driving mechanism includes a mounting plate 300, a connecting assembly 400 and a first driving member 500, wherein the mounting plate 300 is provided with a track groove 310, the track groove 310 includes a first track segment 311, a second track segment 312 and a third track segment 313 connected in sequence, one end of the connecting assembly 400 is movably inserted into the track groove 310, and the other end is connected to the adsorption head 200, and the output end of the first driving member 500 is rotatably passed through the mounting plate 300 and connected to the connecting assembly 400, for The connecting component 400 is driven to move along the track groove 310; when the connecting component 400 moves along the first track segment 311, it can drive the adsorption head 200 to move along the Z-axis direction to adsorb the tape; when the connecting component 400 moves along the second track segment 312, it can drive the adsorption head 200 to rotate and align with the glue-applying surface 810 or the glue-supplying table 110; when the connecting component 400 moves along the third track segment 313, it can drive the adsorption head 200 to move along the X-axis direction to apply glue to the glue-applying surface 810. This design uses the mechanical guidance structure of the three-stage continuous track groove 310, and only requires one drive component to control the adsorption head 200 to complete the complete process of glue removal, steering, and gluing. On the one hand, it eliminates the operation step of flipping the battery cell 800 in the traditional process, reduces the two posture adjustment processes, and significantly improves the gluing efficiency; on the other hand, it makes the overall structure of the device more concise, reducing manufacturing and maintenance costs.

[0037] like Figures 1 to 4As shown, in this embodiment, the gluing device is mainly used to perform side wall gluing operations on the battery cell 800 in a vertical position. The gluing device includes a glue supply component 100, a gluing component, and a driving mechanism. The glue supply component 100 is used to provide the tape material to be adsorbed; the driving mechanism is located on one side of the glue supply component 100 and serves as the core power source for the entire gluing operation; the glue supply component is located above the glue supply component 100 and is connected to the driving mechanism. It can move along a set trajectory under the drive of the driving mechanism, and complete the composite actions of longitudinal glue removal, rotational alignment, and lateral gluing in sequence, and finally accurately adhere the tape to the side wall of the battery cell 800 in a vertical state.

[0038] Specifically, in this embodiment, a horizontally arranged glue supply table 110 is provided on the glue supply assembly 100 for carrying and positioning the adhesive tape. The glue supply assembly 100 is of existing design, and its specific structure and working principle are not described in detail here.

[0039] Preferably, in this embodiment, a drive module is further provided below the glue supply assembly 100 to enhance the position adjustment capability of the glue supply assembly 100. The drive module comprises a first drive module and a second drive module arranged in a cross-stacked arrangement. The first drive module can drive the glue supply assembly 100 to move along the X-axis, and the second drive module can drive the glue supply assembly 100 and the first drive module to move synchronously along the Y-axis. This design ensures that the glue supply table 110 can be precisely positioned below the adsorption head 200. At the same time, the user can dynamically adjust the position of the glue supply table 110 according to actual production needs, significantly improving the flexibility and adaptability of the glue application device.

[0040] In this embodiment, the adhesive tape assembly includes an adsorption head 200 and an air supply structure (not shown). The adsorption head 200 is used to absorb the tape and, driven by a drive mechanism, can perform complex actions such as longitudinal adhesive removal, rotational alignment, and transverse adhesive application. The air supply structure is connected to the adsorption head 200 and is used to provide positive or negative pressure gas to the adsorption head 200 to achieve the adsorption and release operations of the tape.

[0041] In this embodiment, the air supply structure includes an air source module, a reversing valve and a connecting pipeline. By controlling the working state of the reversing valve, it can be switched to a negative pressure state to adsorb the tape before gluing, and switched to a positive pressure state or an air-off state after the gluing is completed, so that the tape can be smoothly detached from the adsorption head 200 and attached to the side wall of the battery cell 800.

[0042] In this embodiment, the suction head 200 includes a connecting plate 210 and a suction plate 220. One side of the connecting plate 210 is connected to the connecting rod 410, and the other side is connected to the suction plate 220 via an elastic member 230. This allows the suction plate 220 to float up and down relative to the connecting plate 210 within a certain range. This design not only facilitates flexible contact with the surface of the battery cell 800 during the adhesive application process, but also facilitates the third sensor 470 to accurately determine the adhesive suction or application position.

[0043] Specifically, the adsorption plate 220 is provided with a third sensing portion 240 that movably passes through the connecting plate 210, and the connecting rod 410 is provided with a third sensing member 470 electrically connected to the first driving member 500. The third sensing member 470 is used to detect position changes of the third sensing portion 240. When the adsorption plate 220 contacts the adhesive tape during the adhesive removal process, or abuts the adhesive surface 810 of the battery cell 800 through the adhesive tape during the adhesive application process, the elastic member 230 is compressed and deformed, driving the third sensing portion 240 toward the connecting plate 210 and into the sensing area of ​​the third sensing member 470, thereby triggering signal feedback. This allows the first driving member 500 to switch its rotation direction based on the signal, for example, from forward to reverse, or from reverse to forward, thereby achieving precise control of the motion path of the adsorption head 200.

[0044] In this embodiment, the connecting plate 210 and the adsorption plate 220 are both rectangular structures. A rectangular through hole matching the third sensing part 240 is opened on the connecting plate 210 to ensure that the third sensing part 240 can move smoothly in the through hole to avoid affecting the position detection accuracy due to jamming.

[0045] Preferably, in this embodiment, the connecting plate 210 and the connecting rod 410 are arranged perpendicular to each other and are detachably connected by fasteners. This design not only facilitates the overall assembly and disassembly maintenance of the adsorption head 200 assembly, but also ensures that the connection part has good structural stability and spatial positioning accuracy.

[0046] In this embodiment, a plurality of suction holes are provided on the bottom horizontal surface of the adsorption plate 220, and each suction hole is connected to the air supply structure through an internal channel to ensure uniform distribution of the adsorption force on the tape, thereby improving the stability and reliability of the gluing process.

[0047] Preferably, in this embodiment, the elastic member 230 is a connecting column with a built-in spring, one end of which is fixedly connected to the adsorption plate 220 and the other end is detachably connected to the connecting plate 210. This design not only enables the adsorption plate 220 to provide a flexible buffer during the adhesive application process, but also facilitates the replacement and maintenance of the elastic member 230, thereby improving the maintainability and service life of the device.

[0048] In this embodiment, the drive mechanism includes a support frame 600, a mounting plate 300, a connecting assembly 400, a first driving member 500, and a second driving member 700. The support frame 600 serves as the main load-bearing component of the entire drive mechanism, and is used to support and position other components. The mounting plate 300 is disposed on top of the support frame 600, and is used to carry the connecting assembly 400 and control its motion trajectory. The first driving member 500 is used to drive the connecting assembly 400 to move along a preset trajectory to achieve a multi-degree-of-freedom compound motion of the adsorption head 200. The second driving member 700 is used to drive the mounting plate 300 to adjust its height in the longitudinal direction (i.e., the Z-axis direction) to adapt to the adhesive height requirements of the battery cell 800 or the adhesive supply assembly 100 under different working conditions.

[0049] In this embodiment, the support frame 600 is vertically arranged on one side of the glue supply assembly 100, one end of which is detachably fixed to the workbench by a fastener, and the other end extends away from the workbench to provide sufficient space layout for the glue laminating operation.

[0050] In this embodiment, the mounting plate 300 is movably disposed on the top of the support frame 600 and can be raised and lowered along the length direction of the support frame 600 under the action of the second driving member 700, thereby achieving flexible adjustment of the adhesive height.

[0051] In this embodiment, a track groove 310 is provided on the mounting plate 300, and the track groove 310 includes a first track segment 311, a second track segment 312, and a third track segment 313 that are connected in sequence. Among them, the first track segment 311 is used to guide the connection component 400 to move along the Z-axis direction to realize the glue-taking action of the adsorption head 200; the second track segment 312 is used to guide the connection component 400 to drive the adsorption head 200 to rotate, so that the adsorption head 200 is aligned with the glue-applying surface 810 of the battery cell 800 to complete the posture adjustment; the third track segment 313 is used to guide the connection component 400 to move along the X-axis direction to realize the glue-applying action of the adsorption head 200. This design enables the adsorption head 200 to complete the composite actions of longitudinal glue-applying, rotational alignment, and lateral glue-applying in sequence under the action of a single driving member, which not only simplifies the overall structure of the driving mechanism, but also improves the degree of automation and execution efficiency of the glue-applying process.

[0052] In this embodiment, the first and third track segments 311, 313 are straight lines with a 90° angle between them. The second track segment 312 is circular, with its ends connected to the first and third track segments 311, 313, respectively, to achieve a smooth transition in the motion path. This design not only ensures the accuracy of the angle control of the suction head 200 during rotation, but also effectively improves the continuity and smoothness of its movement during the adhesive removal, steering, and adhesive application stages.

[0053] In this embodiment, a rotating seat 320 is rotatably provided on the mounting plate 300, and a slide groove 321 is provided on the side of the rotating seat 320 facing away from the mounting plate 300, which is used to achieve a sliding connection with the connecting rod 410. When the movable shaft 420 on the connecting rod 410 moves within the second track section 312, the rotating seat 320 rotates around its own axis and drives the connecting rod 410 to rotate synchronously, thereby achieving posture adjustment of the adsorption head 200. This design does not require the additional configuration of an independent rotation drive component, and can achieve the automatic rotation function of the adsorption head 200 through track guidance and mechanical linkage. It is not only compact in structure and simple to control, but also effectively reduces the complexity and manufacturing cost of the device.

[0054] Furthermore, the sliding fit between the connecting rod 410 and the slide slot 321 ensures that the connecting rod 410 can move in the Z-axis direction along the first track segment 311 or in the X-axis direction along the third track segment 313. This design not only improves the precision and stability of the motion guidance, but also provides reliable mechanical support for the posture adjustment of the suction head 200 during different motion phases, thereby further improving the repeatability of the adhesive application and the overall reliability of the operation.

[0055] In this embodiment, the connecting line between the rotation center of the rotating seat 320 and the rotation center of the movable plate 510 is located between the first track segment 311 and the third track segment 313, and the connecting line is equal to the angle formed between the first track segment 311 and the third track segment 313. Preferably, the angle is 45°. That is, the connecting line between the rotation center of the rotating seat 320 and the movable plate 510 is exactly located on the bisector of the right angle formed by the first track segment 311 and the third track segment 313. This design ensures that the path of the rotation action of the adsorption head 200 is symmetrical and the force is uniform during the conversion process from longitudinal movement to lateral movement, thereby improving the smoothness of the rotation process and the accuracy of angle control. At the same time, it is also beneficial to reduce the stress concentration phenomenon in the mechanical transmission and improve the operating stability and service life of the structure.

[0056] In this embodiment, the rotation center of the rotating base 320 is located at the intersection of the extension lines of the first track segment 311 and the third track segment 313. The straight-line distance between the rotation center of the rotating base 320 and the rotation center of the movable plate 510 is equal to the length of the first track segment 311 and the third track segment 313. This design not only ensures smooth rotation of the adsorption head 200, but also effectively shortens the load-bearing arm length of the connecting rod 410 and the movable plate 510, thereby reducing the structural space occupied and improving the compactness and stability of the overall layout.

[0057] In this embodiment, a first sensing member 330 and a second sensing member 340 electrically connected to the first driving member 500 are respectively provided on the mounting plate 300. The first sensing member 330 is used to detect position changes of the first sensing portion 430, and the second sensing member 340 is used to detect position changes of the second sensing portion 440. When the first sensing portion 430 enters the sensing area of ​​the first sensing member 330, the first sensing member 330 sends a feedback signal to the first driving member 500, triggering the control logic to restrict the first driving member 500 from continuing to operate, thereby preventing the connecting rod 410 from overtraveling within the first track segment 311. Similarly, when the second sensing portion 440 enters the sensing area of ​​the second sensing member 340, the second sensing member 340 also sends an electrical signal to the first driving member 500 to restrict it from continuing to operate, thereby preventing the connecting rod 410 from overtraveling within the third track segment 313.

[0058] Preferably, in this embodiment, the first sensing member 330 is detachably provided on the adjacent side of the end of the first track segment 311, and a first sensing slot is provided at its end for the first sensing portion 430 to freely enter and exit, so as to limit the travel of the connecting rod 410 in the Z-axis direction; the second sensing member 340 is detachably provided on the adjacent side of the end of the third track segment 313, and a second sensing slot is provided at its end for the second sensing portion 440 to enter and exit, so as to limit the travel of the connecting rod 410 in the X-axis direction.

[0059] Preferably, in this embodiment, the first and second sensing elements 330, 340 are each configured in two groups and arranged side by side along the extension direction of their respective track segments. One group of first and second sensing elements 330, 340 is used to trigger the first driving element 500 to return to zero when the suction head 200 reaches the target position; the other group is used to trigger the limit protection at the extreme position to prevent mechanical overload or equipment damage caused by program abnormalities or sensor failure.

[0060] Preferably, in this embodiment, both the first sensing element 330 and the second sensing element 340 are position sensors, specifically including but not limited to photoelectric switches. The use of high-precision position sensors such as photoelectric switches not only enables accurate detection of the motion state of the connecting rod 410, but also effectively improves the automation control level and operational reliability of the adhesive application device.

[0061] In this embodiment, the mounting plate 300 is further provided with a first limiting member 350 and a second limiting member 360, which are used to cooperate with the first limiting portion 450 and the second limiting portion 460 on the connecting rod 410 to achieve mechanical limiting protection for the movement stroke of the connecting rod 410.

[0062] Preferably, in this embodiment, the first limiter 350 is removably disposed adjacent to the end of the first track segment 311. When abutting the first limiter 450, it can restrict the connecting rod 410 from continuing to move in the original direction along the first track segment 311, thereby physically limiting the connecting rod 410 in the Z-axis direction. The second limiter 360 is also removably disposed adjacent to the end of the third track segment 313. When abutting the second limiter 460, it can restrict the connecting rod 410 from continuing to move in the original direction along the third track segment 313, thereby physically limiting the connecting rod 410 in the X-axis direction. This design ensures structural reliability while providing an additional safety mechanism. Even if the first and second sensors 330 and 340 fail or their signals are abnormal, mechanical limiting can still prevent the connecting rod 410 from exceeding the safe travel range, effectively avoiding equipment damage or operational abnormalities caused by control system failure, further improving the stability and safety of the adhesive laminating device.

[0063] In this embodiment, the connecting assembly 400 includes a connecting rod 410 and a movable shaft 420. One end of the connecting rod 410 is vertically connected to the connecting plate 210 of the adsorption head 200, and the other end extends in a direction away from the adsorption head 200; the movable shaft 420 is vertically arranged on the extended end of the connecting rod 410, and is movably inserted into the movable groove 511 and the track groove 310 in sequence to form a guide fit; when the first driving member 500 is working, the movable plate 510 can be used to drive the movable shaft 420 to drive the connecting rod 410 to move along the movable groove 511 and the track groove 310, thereby realizing the composite action control of the adsorption head 200 in the Z-axis direction, the rotation alignment, and the X-axis direction.

[0064] In this embodiment, the connecting rod 410 includes a guide rail structure 411 and a fixed base 412, which are vertically arranged and detachably connected. The guide rail structure 411 forms a sliding fit with the slide groove 321 on the rotating base 320, which is used to guide the movement of the connecting rod 410 along the track groove 310. The fixed base 412 has an inverted T-shaped structure and is detachably connected to the connecting plate 210 of the adsorption head 200 via fasteners, facilitating assembly and replacement.

[0065] In this embodiment, the connecting rod 410 further includes a fixing block 413, which is detachably mounted on the side of the guide rail structure 411 facing away from the mounting plate 300 and located at the end of the guide rail structure 411 away from the fixing base 412. The fixing block 413 is used to mount the first sensing portion 430, the second sensing portion 440, and the first and second limiting portions 450, 460, serving as key components for detecting the travel of the drive mechanism and for mechanical limiting.

[0066] In this embodiment, a first sensing portion 430 and a second sensing portion 440 are detachably mounted on either side of the fixed block 413 of the connecting rod 410. These first and second sensing portions 430, 440 are symmetrically arranged, perpendicularly connected to the fixed block 413, and extend in opposite directions to mate with the corresponding first and second sensing members 330, 340. When the connecting rod 410 moves along the first track segment 311 to a first predetermined position (i.e., the extreme position of the first track segment 311), the first sensing portion 430 enters the sensing area of ​​the first sensing member 330, triggering an electrical signal feedback to control the first driving member 500 to stop or switch its movement direction. When the connecting rod 410 moves along the third track segment 313 to a second predetermined position (i.e., the extreme position of the third track segment 313), the second sensing portion 440 enters the sensing area of ​​the second sensing member 340, similarly triggering a signal feedback to implement position-limiting control of the driving action. This design enables precise detection and control of the travel of the connecting rod 410, ensuring the reliability and safety of the adhesive laminating device during automatic operation.

[0067] In this embodiment, a first stopper 450 and a second stopper 460 are detachably provided on either side of the fixed block 413 of the connecting rod 410. Both the first stopper 450 and the second stopper 460 are strip-shaped, block-like structures, arranged symmetrically. They are perpendicularly connected to the fixed block 413 and extend in opposite directions to mate with the first stopper 350 and the second stopper 360. This design, through cooperation with the first and second stoppers 360, provides a physical limit protection function when the drive mechanism reaches its limit position, preventing damage to the equipment caused by overtravel of the connecting rod 410.

[0068] In this embodiment, the first driving member 500 is detachably disposed on the mounting plate 300 and connected to the connecting assembly 400, and is used to drive the connecting assembly 400 to sequentially complete composite actions such as longitudinal glue removal, rotational alignment, and transverse glue application along the track groove 310.

[0069] In the embodiment, the output end of the first driving member 500 is rotatably penetrated through the mounting plate 300 from the back surface of the mounting plate 300, and the movable plate 510 is detachably arranged on the output end. The movable plate 510 is in a strip-shaped structure, and the movable groove 511 extending along the length direction of the movable plate 510 is arranged on the movable plate 510. When the first driving member 500 works, the output end drives the movable plate 510 to rotate synchronously, the movable groove 511 on the movable plate 510 is in sliding fit with the movable shaft 420 on the connecting rod 410, and the movable shaft 420 is driven to move along the guiding path of the movable groove 511 and the track groove 310, so that the connecting rod 410 sequentially completes the longitudinal glue taking, the rotation alignment and the transverse glue pasting and other composite actions according to the predetermined track. The linkage structure between the movable plate 510 and the movable groove 511 realizes the accurate control of the single driving source on the multi-degree-of-freedom glue pasting action, simplifies the overall structure of the driving mechanism, and improves the action coordination and control accuracy in the glue pasting process.

[0070] In the embodiment, one side of the second driving member 700 is detachably fixed to the support frame 600 through the fastener, and the other side is connected with the mounting plate 300 to drive the mounting plate 300 to move up and down along the length direction of the support frame 600. The design improves the adaptability of the glue pasting device to different specifications (different heights) of the battery cell 800, and enhances the flexibility and universality of the device in actual application.

[0071] As shown in Figure 5 The glue pasting device provided in the embodiment can be used in cooperation with a battery cell fixing device. The battery cell fixing device is provided with a chuck for clamping the battery cell 800, and the battery cell 800 is clamped on the chuck in a vertical posture. The battery cell 800 has a glue pasting surface 810 perpendicular to the horizontal plane, so that the suction head 200 can perform the transverse glue pasting operation. The glue supply table 110 is located on the adjacent side below the chuck of the battery cell 800, and is arranged perpendicularly to the glue pasting surface 810 of the battery cell 800, so that the suction head 200 can rotate or move along the set track between the glue supply table 110 and the glue pasting surface 810 to complete the complete work flow from glue taking to glue pasting. The structural layout not only facilitates efficient glue pasting operation on the battery cell 800 in a vertical state, but also effectively improves the space utilization and action continuity in the glue pasting process, and provides a good structural basis for automatic glue pasting operation of the whole machine.

[0072] In the embodiment, the working principle of the glue pasting device is as follows:

[0073] When the glue pasting process is started, the first driving member 500 starts to work, the output end of the first driving member 500 drives the movable plate 510 to rotate, the movable groove 511 on the movable plate 510 is in sliding fit with the movable shaft 420 in the connecting assembly 400, and the connecting assembly 400 is driven to move along the track groove 310 on the mounting plate 300.

[0074] The suction head 200 first moves along the first track segment 311 of the track groove 310 with the connecting assembly 400 in the Z-axis direction. After contacting the adhesive supply surface 110, the air supply structure provides negative pressure gas to the suction head 200, sucking the tape to the surface through the multiple suction holes provided at the bottom of the suction plate 220, completing the adhesive removal operation. During this process, the suction plate 220 can float up and down relative to the connecting plate 210 due to the cushioning effect of the elastic member 230. When the suction plate 220 contacts the tape surface, the third sensing unit 240 moves with the suction plate 220 and enters the sensing area of ​​the third sensing element 470, triggering a signal feedback to confirm that the adhesive suction operation is in place and controlling the first driving member 500 to switch its movement direction.

[0075] Subsequently, the first driving member 500 reverses, driving the connecting assembly 400 along the first track segment 311 into the second track segment 312. During the movement, the connecting rod 410 drives the rotating seat 320 to rotate synchronously, causing the adsorption head 200 to rotate 90° around the rotation center of the rotating seat 320 and remain aligned with the adhesive surface 810 of the battery cell 800.

[0076] Next, the connecting assembly 400 continues to move along the third track segment 313 in the track groove 310 in the X-axis direction, and the adsorption head 200 transports the adsorbed tape horizontally to the vicinity of the adhesive surface 810 of the battery cell 800. At this time, the air supply structure switches to a positive pressure state or an air-off state, allowing the tape to detach from the adsorption head 200 and adhere to the surface of the battery cell 800, completing the adhesive application operation. During this process, when the adsorption plate 220 contacts the surface of the battery cell 800, the third sensing portion 240 moves with the adsorption plate 220 and enters the sensing area of ​​the third sensing member 470, triggering signal feedback to confirm that the adhesive application action is in place and controlling the first driving member 500 to switch its movement direction. This allows the next round of adhesive application to begin.

[0077] During the entire operation process, the first sensing part 430 and the second sensing part 440 provided on both sides of the fixing block 413 of the connecting rod 410 respectively enter the sensing area of ​​the first sensing member 330 and the second sensing member 340 at the extreme position, triggering the limit signal to prevent the connecting rod 410 from over-travel movement; at the same time, the first limiting part 450 and the second limiting part 460 respectively abut against the first limiting member 350 and the second limiting member 360 to realize mechanical limit protection and ensure the safety and stability of the equipment operation.
