Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a foam bonding mechanism. Background Technology

[0002] When stacking pouch cells, a heat insulation pad needs to be placed between two adjacent cells. The industry typically uses foam as the heat insulation pad, which is then bonded to the cell using adhesive. For example... Figure 10 As shown, foam component a includes foam layer a1 and release paper adhered to both sides of foam layer a1. Typically, the lower release paper a3 is peeled off and adhered to the battery cell, then the upper release paper a2 is peeled off. Figure 10 As shown, one side of the upper tear-off ear a21 is flush with the side edge of the upper release paper a2 in the width direction. The other side of the upper tear-off ear a21 has an upper stress angle a22 at the junction with the end edge of the upper release paper a2 in the length direction. During the process of tearing off the upper release paper a2, the upper stress angle a22 is prone to cracking, causing the upper tear-off ear a21 to tear or even break, affecting the tearing off of the upper release paper a2. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foam bonding mechanism that can prevent the upper release tab from breaking and facilitate the smooth separation of the upper release paper from the foam component.

[0004] The embodiments of this utility model are achieved through the following technical solutions:

[0005] A foam bonding mechanism includes a frame, on which an adhesive application mechanism, an adhesive removal mechanism, and a trimming assembly are sequentially arranged along a first direction. The mechanism also includes a conveyor belt assembly disposed on the frame, which carries a battery cell along the first direction, allowing the battery cell to sequentially pass through the adhesive application mechanism, the adhesive removal mechanism, and the trimming assembly. The adhesive removal mechanism includes a first upright, a hanging plate, an upper pressure block, and a lower pressure block. The hanging plate is adjustablely disposed on the first upright along a second direction. A first actuating cylinder is disposed at the lower end of the first upright, acting on the upper pressure block to move it horizontally. A second actuating cylinder is disposed on the upper pressure block, acting on the lower pressure block to abut against or detach from the upper pressure block vertically. The length direction of the battery cell is parallel to the second direction. The first actuating cylinder drives the upper pressure block to cooperate with the lower pressure block, causing the upper adhesive removal tab to flip towards the side of the upper stress angle. With this configuration, the first actuating cylinder enables the upper and lower pressure blocks to clamp the upper release tab after it is gripped. The upper release tab can then be flipped toward the side of the upper stress angle, thus separating the end of the upper release paper near the upper release tab from the foam layer. The structural strength of the upper release tab and the upper release paper on the side that is flush with each other in the width direction is higher than that on the side of the upper stress angle. In the early stage, separating the upper release paper and the foam layer by flipping it toward the side of the upper stress angle can prevent the upper release tab from being torn, which is conducive to the smooth separation of the upper release paper and the foam layer.

The clamp includes a main support plate slidably mounted on the belt mounting frame, the main support plate being connected to and driven by the conveyor belt to move along a second direction. The main support plate is provided with a length branch plate and a width branch plate.

[0028] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Please refer to Figures 1 to 10A foam bonding mechanism includes a frame 1, on which an adhesive application mechanism 3, an adhesive removal mechanism 4, and a trimming assembly 5 are sequentially arranged along a first direction X. The mechanism also includes a conveyor belt assembly 6 mounted on the frame 1. The conveyor belt assembly 6 carries a battery cell 7 along the first direction X, allowing the battery cell 7 to sequentially pass through the adhesive application mechanism 3, the adhesive removal mechanism 4, and the trimming assembly 5. The adhesive removal mechanism 4 includes a first upright 41, a hanging plate 42, an upper pressure block 43, and a lower pressure block 44. The hanging plate 42 is adjustablely mounted on the first upright 41 along a second direction Y. A first actuating cylinder 431 is provided at the lower end of a support frame 41. The first actuating cylinder 431 acts on the upper pressure block 43 to enable it to move in the horizontal direction. A second actuating cylinder 432 is disposed on the upper pressure block 43. The second actuating cylinder 432 acts on the lower pressure block 44 to enable it to abut or disengage from the upper pressure block 43 in the vertical direction Z. The length direction of the battery cell 7 is parallel to the second direction Y. The first actuating cylinder 431 drives the upper pressure block 43 to cooperate with the lower pressure block 44 so that the upper adhesive tab a21 flips toward the side of the upper stress angle a22. Figure 1 As shown, a transfer platform 2 is provided on the frame 1 for placing foam component a with its lower release paper removed. During use, the adhesive applicator 3 transfers foam component a from the transfer platform 2 to the battery cell 7 for adhesive application. After adhesive application, the battery cell 7, driven by the conveyor belt assembly 6, reaches the adhesive removal mechanism 4 to remove the upper release paper a2. After removal, the battery cell 7 is further transferred by the conveyor belt assembly 6 to the trimming assembly 5 for trimming. It should be noted that when this foam component adhesive mechanism is in use, the lower release paper of the foam component a has already been removed; that is, the removal of the lower release paper is not within the scope of this application.

[0032] Specifically, in use, the upper release tab a21 is positioned between the upper pressure block 43 and the lower pressure block 44. The second actuating cylinder 432 drives the lower pressure block 44 to move towards the upper pressure block 43 to clamp the upper release tab a21. The first actuating cylinder 431 moves horizontally to initially separate the upper release paper a2 from the foam layer a1 in the vicinity of the upper release tab a21. Subsequently, the hanging plate 42 moves along the second direction Y under the action of the linear module to completely separate the upper release paper a2 from the foam layer a1 adhered to the battery cell 7. Preferably, as shown in the figure... Figure 5As shown, one side of the upper tear-off ear a21 is flush with the side edge of the upper release paper a2 in the width direction, and the other side of the upper tear-off ear a21 has an upper stress angle a22 at the junction with the end edge of the upper release paper a2 in the length direction. The upper pressure block 43 cooperates with the lower pressure block 44 to drive the upper tear-off ear a21 to flip toward the side of the upper stress angle a22. The path of the upper pressure block 43 under the action of the first action cylinder 431 is the pre-tear path a23, that is, driving the upper tear-off ear a21 to flip from left to right and from top to bottom along the second direction Y, so as to avoid the upper stress angle a22 being over-stressed and torn. After the upper end of the upper release paper a2 is torn off the foam layer a1, the first action cylinder 431 stops operating. At this time, the hanging plate 42 moves along the second direction Y to completely tear off the upper release paper a2.

[0033] like Figure 2 As shown, the adhesive applicator 3 includes a second stand 31, on which a gripper frame 32 is adjustablely mounted along the second direction Y, and a negative pressure assembly 34 for gripping foam component a is adjustablely mounted along the vertical direction Z on the gripper frame 32. The negative pressure assembly 34 includes a transition plate 341 and a negative pressure suction plate 342. The transition plate 341 is connected to the gripper frame 32 via a first slide cylinder 33, and the negative pressure suction plate 342 is mounted on the transition plate 341 via a guide shaft 343. A buffer spring 344 is sleeved on the guide shaft 343, and the buffer spring 344 is located between the transition plate 341 and the negative pressure suction plate 342. The guide shaft 343 passes through the transition plate 341 and is slidably connected to it.

[0034] Optionally, a limit rod 345 is provided at the top of the guide shaft 343 to prevent the negative pressure suction plate 342 from detaching from the transition plate 341 under the action of gravity.

[0035] In some embodiments, the two guide shafts 343 may share the same limiting rod 345. The buffer spring 344 is used to prevent the negative pressure suction plate 342 from making hard contact with the foam part a, so that the two are fully fitted to ensure negative pressure adsorption and gripping of the foam part a.

[0036] Optionally, the negative pressure suction plate 342 is integrated with several suction cups (not shown in the figure).

[0037] like Figure 1 and Figure 6 As shown, the trimming assembly 5 includes a third upright 51, an adjusting frame 52, a transition plate 53, and a pressure roller 532. The adjusting frame 52 is adjustablely mounted on the third upright 51 along the second direction Y. The transition plate 53 is mounted on the adjusting frame 52, and a roller frame 531 is adjustablely mounted on the transition plate 53 along the vertical direction Z. The pressure roller 532 is rotatably mounted on the roller frame 531. Specifically, as... Figure 6As shown, the roller frame 531 is adjustablely mounted on the adapter plate 53 in the vertical direction Z via the second slide cylinder 533. In use, after the upper release paper a2 is removed, the foam layer a1 is pressed by the pressure roller 532 to ensure that it is completely attached to the battery cell 7, preventing the foam layer a1 from detaching from the battery cell 7 after the upper release paper a2 is removed.

[0038] Furthermore, the trimming assembly 5 also includes a detection module 54 disposed on the adjustment frame 52 for detecting whether the upper release paper a2 has been completely removed. Optionally, the detection module 54 is a CCD camera.

[0039] Based on this, for battery cell 7 where the release paper a2 on the upper side is not completely removed, an NG procedure must be performed. In order to meet the NG functional requirements, such as... Figure 6 and Figure 7 As shown, a lifting cylinder 534 is configured on the adapter plate 53, and a first pneumatic finger 535 is configured on the lifting cylinder 534. The first pneumatic finger 535 is driven by the lifting cylinder 534 to achieve vertical Z-direction movement; the first pneumatic finger 535 is equipped with a gripper 536 for grasping the battery cell 7. Figure 1 As shown, the NG material belt 56 is perpendicular to the conveying direction of the conveyor belt assembly 6. Therefore, in this embodiment, the adapter plate 53 and the adjustment frame 52 are connected by a rotary cylinder 55. When the NG battery cell 7 is needed, the gripper 536 picks up the battery cell 7 from the conveyor belt assembly 6, rotates it 90° and moves it along the second direction Y to transfer it to the NG material belt 56.

[0040] like Figure 1 and Figure 8 As shown, the conveyor belt assembly 6 includes a material belt mounting frame 61 disposed on the frame 1. A conveyor belt 62 is mounted on the material belt mounting frame 61, and a clamp 63 for positioning the battery cell 7 is disposed on the conveyor belt 62. The battery cell 7 clamp 63 includes a main support plate 631 slidably mounted on the material belt mounting frame 61. The main support plate 631 is connected to the conveyor belt 62 and driven by it to move along the second direction Y. The main support plate 631 is provided with a length branch plate 633 and a width branch plate 632. The length branch plate 633 is provided with a length pre-limiting surface 6331, and the width branch plate 632 is provided with a width pre-limiting surface 6321. There are two length branch plates 633 and two width branch plates 632. The two width pre-limiting surfaces 6321 are arranged opposite each other in the first direction X, and the two length pre-limiting surfaces 6331 are arranged opposite each other in the second direction Y, for initial positioning of the battery cell 7. In use, the length branch plate 633 is used to support the battery cell 7 in the vertical direction Z. In this embodiment, the sliding installation structure of the main support plate 631 and the material strip mounting frame 61 is existing technology and will not be described in detail here.

[0041] Furthermore, the conveyor belt assembly 6 also includes two positioning modules 60 disposed on both sides of the conveyor belt 62. The positioning modules 60 are correspondingly disposed with the adhesive applicator 3. The positioning modules 60 include a first positioning member 64 mounted on the frame 1 and a second positioning member 65 mounted on the belt mounting bracket 61. The first positioning member 64 includes a first mounting base 641 disposed on the frame 1. A first positioning cylinder 642 is disposed at the top of the first mounting base 641. A length positioning block 643 is disposed at the end of the piston rod of the first positioning cylinder 642. The first positioning cylinder 642 is used to drive the length positioning block 643 to move along the second direction Y to approach or move away from the main support plate 631, so as to achieve positioning of the battery cell 7 in the second direction Y, that is, the length direction of the battery cell 7; Figure 8 and Figure 9 As shown, the second positioning component 65 includes a second mounting base 651 disposed on the material strip mounting frame 61. A second positioning cylinder 652 is disposed at the top of the second mounting base 651. A second pneumatic finger 653 is disposed at the end of the piston rod of the second positioning cylinder 652. A width positioning block 654 is mounted on the second pneumatic finger 653. The second positioning cylinder 652 is used to drive the second pneumatic finger 653 to move in the vertical direction Z. The second pneumatic finger 653 is used to drive the two width positioning blocks 654 to move closer to each other or further away from each other in the first direction X, so as to position the battery cell 7 in the first direction X, that is, the width direction of the battery cell 7.

[0042] It should be noted that, as Figure 1 As shown, the conveyor belt 62 is equipped with several main support plates 631. When the battery cell 7 on the main support plate 631 moves to the adhesive applicator 3, the first positioning member 64 and the second positioning member 65 can position the battery cell 7 on the main support plate 631 so as to cooperate with the adhesive applicator 3 to achieve the bonding of the foam part a and the battery cell 7.

[0043] In this embodiment, the first upright 41, the second upright 31 and the third upright 51 are all installed on the frame 1.

[0044] In this embodiment, the surface of the transfer table 2 and the roller surface of the pressure roller 532 are both provided with an anti-stick coating, preferably a polytetrafluoroethylene coating.

[0045] like Figure 11 As shown, this embodiment also provides a method for applying adhesive to foam parts, applied to the aforementioned foam part bonding mechanism, including the following steps:

[0046] Step S1: Attach foam component a to battery cell 7;

[0047] Step S2: The upper pressure block 43 cooperates with the lower pressure block 44 to clamp the upper tear ear a21, and the upper pressure block 43 and the lower pressure block 44 move synchronously so that the upper tear ear a21 flips toward the side of the upper stress angle a22 until the upper release paper a2 near the end of the upper tear ear a21 is separated from the foam layer a1.

[0048] Step S3: The upper pressure block 43 and the lower pressure block 44 move synchronously in the second direction Y to tear off the upper release paper a2.

[0049] Through the above steps, the upper release paper a2 and foam component a can be separated efficiently and effectively while maintaining the integrity of the upper release ear a21 structure.

[0050] Furthermore, after step S3, the following steps are also included:

[0051] Step S4: Roll the foam layer a1 along the second direction Y.

[0052] The foam layer a1 is pressed by the pressure roller 532 to ensure that it is completely bonded to the battery cell 7, and to prevent the foam layer a1 from separating from the battery cell 7 after the upper release paper a2 is removed.

[0053] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
