Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a device for dispensing adhesive for electrode tabs. Background Technology

[0002] Tabs are a raw material used in lithium-ion polymer batteries. For example, they are used in everyday items such as mobile phone batteries, Bluetooth batteries, and laptop batteries. Batteries have positive and negative terminals, and tabs are the metal conductors that connect the positive and negative terminals from the battery cell. The tab adhesive is the insulating part on the tab; its function is to prevent short circuits between the metal strip and the aluminum-plastic film during battery encapsulation, and to prevent leakage by heat-sealing and bonding it to the aluminum-plastic film during encapsulation.

[0003] Applying adhesive to the tabs is a process that follows welding the tabs to the battery cell. Before applying the adhesive, the adhesive needs to be transported to the application station. Currently, in the power battery manufacturing industry, the adhesive is transported to the application station via a material guide chute. Because the adhesive material is relatively soft and thin, it is prone to deformation. During production, the adhesive often rubs against the pressure plate, sometimes causing even greater deformation and resulting in the adhesive getting stuck in the material guide chute. This can lead to significant adverse consequences such as machine downtime, severely impacting production efficiency. Utility Model Content

[0004] One objective of this invention is to overcome the shortcomings of existing technologies and provide a glue feeding device for tab adhesive. To solve the above-mentioned technical problems, this invention adopts the following technical solution: A device for dispensing tab adhesive, comprising: Horizontal support; A vertical support is connected vertically to one end of a horizontal support, and an output channel is provided on the vertical support. The guide fork is slidably mounted on a horizontal support. The guide fork has two guide fork teeth arranged vertically and vertically. Each guide fork tooth has a guide groove that runs through both ends of the guide fork. The guide groove is used to pass through the tab rubber. The discharge end of the guide fork can output the tab rubber to the next station through the output channel. The clamping assembly is connected to the feed end of the guide fork carriage and is used to clamp the tab rubber onto the guide fork carriage. The first pressing assembly is mounted on a vertical support. The first pressing assembly includes a first driving member and two first pressing blocks. The two first pressing blocks are located between two guide fork teeth. The first driving member is used to drive the two first pressing blocks away from each other so that parts of the two first pressing blocks can respectively extend into the two guide grooves, or drive the two first pressing blocks closer to each other so that the two first pressing blocks respectively exit the two guide grooves. Two second pressing assemblies are mounted on a vertical support and located on the upper and lower sides of the guide fork respectively. Each second pressing assembly includes a second driving member and a second pressing block. The second pressing block is arranged vertically and vertically corresponding to the first pressing block. The second driving member is used to drive the second pressing block to move closer to or away from the corresponding first pressing block in order to clamp or release the tab rubber.

[0005] In one embodiment, a first protrusion is provided on the surface of the first pressing block and the second pressing block facing each other. The width of the first protrusion matches the guide groove so that it can extend into the guide groove.

[0006] In one embodiment, a second protrusion is provided on the surface of the second pressing block opposite to the first pressing block, and the width of the second protrusion matches the guide groove so that it can extend into the guide groove.

[0007] In one embodiment, the first driving member is a parallel pneumatic gripper, and two first pressure blocks are respectively fixed on the two grippers of the parallel pneumatic gripper.

[0008] In one embodiment, the second drive element is a linear cylinder or an electric actuator.

[0009] In one embodiment, the adhesive feeding device for the tabs further includes a mounting bracket and a power component. The mounting bracket is slidably connected to a horizontal support, and the power component is drivenly connected to the mounting bracket and is used to drive the mounting bracket to reciprocate relative to the horizontal support. The feed end of the guide fork is fixedly installed on the mounting bracket, and the rubber clamping assembly is fixedly installed on the mounting bracket.

[0010] In one embodiment, a linear slide rail is provided on the horizontal support, and a sliding seat is connected to the bottom of the mounting bracket, with the sliding seat slidably connected to the linear slide rail. The power components include a lead screw and a motor. The lead screw is threadedly connected to the slide block, and the motor is connected to one end of the lead screw and is used to drive the lead screw to rotate so that the slide block can move along the length of the linear guide rail.

[0011] In one embodiment, there are two linear slide rails, which are respectively disposed on both sides of the lead screw, and the two sides of the sliding seat are slidably connected to the two linear slide rails respectively.

[0012] In one embodiment, the adhesive feeding device for the tabs further includes a clamping roller assembly, which is disposed on a sliding seat and located behind the feed end of the guide fork. The clamping roller assembly includes two clamping rollers arranged in pairs, the distance between the two clamping rollers being adjustable, and the two clamping rollers being used to clamp the tabs.

[0013] In one embodiment, the adhesive clamping assembly includes two third driving members and two third pressing blocks. The two third pressing blocks are respectively arranged corresponding to two guide grooves. The two third driving members are used to drive the two third pressing blocks to move up and down, so that the third pressing blocks can extend into the guide grooves and press the tab adhesive onto the guide fork.

[0014] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this invention, the reciprocating motion of the guide fork conveyor can transport the tab rubber to the next workstation and achieve segmented output of the tab rubber. The clamping assembly can clamp the tab rubber onto the guide fork, allowing it to be transported forward along with the guide fork. The first pressing assembly and two second pressing assemblies can hold the tab rubber in place when it reaches its destination, keeping it fixed in its current position. Then, the clamping assembly can release the tab rubber, allowing the guide fork to move backward and reset, clamping the next segment of tab rubber again, and then transporting the tab rubber forward.

[0015] Furthermore, during the forward conveying of the tab rubber by the guide fork, the two first pressing blocks of the first pressing assembly can be positioned close to each other, with neither first pressing block extending into the guide trough. This ensures the tab rubber in the guide trough is smoothly output forward, avoiding the risk of material blockage caused by friction between the first pressing blocks and the tab rubber. Additionally, the second pressing block of the second pressing assembly can be positioned away from its corresponding first pressing block to avoid friction with the tab rubber and subsequent material blockage, thus ensuring the smooth forward output of the tab rubber in the guide trough.

[0016] Therefore, the glue feeding device of this utility model can not only realize the segmented and continuous output of the tab glue to the next station, but also ensure that the tab glue in the guide trough can be output smoothly, reducing the risk of material blockage during the output process of the tab glue and effectively improving the production efficiency of the tab glue.

If the description of the positions of these elements changes, these directional indications also change accordingly.

[0023] 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 one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Please see Figure 1 and Figure 2 As shown, the adhesive feeding device for tabs according to an embodiment of the present invention (hereinafter referred to as the adhesive feeding device) includes a horizontal support 10, a vertical support 20, a guide fork 30, an adhesive clamping assembly 40, a first pressing assembly 50, and two second pressing assemblies 60. The vertical support 20 is vertically connected to one end of the horizontal support 10, and an output channel 21 is provided on the vertical support 20.

[0025] The guide fork 30 is slidably mounted on the horizontal support 10. The guide fork 30 has two guide fork teeth 31 arranged vertically at intervals. Each guide fork tooth 31 has a guide groove 32 extending through both ends of the guide fork 30, used for inserting the tab rubber. The discharge end of the guide fork 30 can output the tab rubber to the next workstation via the output channel 21. A clamping assembly 40 is connected to the feed end of the guide fork 30, used to clamp the tab rubber onto the guide fork 30.

[0026] refer to Figure 3 As shown, the first pressing assembly 50 is mounted on the vertical support 20. The first pressing assembly 50 includes a first driving member 51 and two first pressing blocks 52. The two first pressing blocks 52 are located between the two guide forks 31. The first driving member 51 is used to drive the two first pressing blocks 52 away from each other so that parts of the two first pressing blocks 52 can respectively extend into the two guide grooves 32, or drive the two first pressing blocks 52 closer to each other so that the two first pressing blocks 52 respectively exit the two guide grooves 32.

[0027] Two second pressing assemblies 60 are mounted on the vertical support 20 and located on the upper and lower sides of the guide fork 30, respectively. Each second pressing assembly 60 includes a second driving member 61 and a second pressing block 62. The second pressing block 62 is arranged vertically and vertically corresponding to the first pressing block 52. The second driving member 61 is used to drive the second pressing block 62 to move closer to or away from the corresponding first pressing block 52, so as to clamp or release the tab rubber.

[0028] The adhesive feeding device of this invention can convey the tab adhesive to the next workstation through the reciprocating motion of the guide fork 30, and achieve segmented output of the tab adhesive. The adhesive clamping assembly 40 can clamp the tab adhesive onto the guide fork 30, allowing the tab adhesive to be conveyed forward along with the guide fork 30. The first pressing assembly 50 and two second pressing assemblies 60 can clamp the tab adhesive when it reaches its position, keeping it fixed in that position. Then, the clamping assembly 40 can release the tab adhesive, allowing the guide fork 30 to move backward and reset, clamping the next segment of tab adhesive again through the clamping assembly 40, and then conveying the tab adhesive forward.

[0029] Furthermore, during the forward conveying of the tab adhesive by the guide fork 30, the two first pressure blocks 52 of the first pressure assembly 50 can be positioned close to each other, without each first pressure block 52 extending into the guide groove 32. This ensures that the tab adhesive in the guide groove 32 is smoothly output forward, avoiding the risk of material blockage caused by friction between the first pressure blocks 52 and the tab adhesive. Additionally, the second pressure block 62 of the second pressure assembly 60 can be positioned away from the corresponding first pressure block 52 to prevent friction between the second pressure block 62 and the tab adhesive, thus ensuring that the tab adhesive in the guide groove 32 can be smoothly output forward.

[0030] Therefore, the glue feeding device of this utility model embodiment can not only realize the segmented and continuous output of the tab glue to the next station, but also ensure that the tab glue in the guide trough 32 can be output smoothly, reducing the risk of material blockage during the output process of the tab glue and effectively improving the production efficiency of the tab glue.

[0031] The specific embodiments of the glue feeding device of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] For ease of understanding and description, in this utility model, the conveying direction of the tab adhesive is defined as the horizontal front-to-back direction, the vertical direction perpendicular to the front-to-back direction is the up-down direction, and the horizontal direction perpendicular to the front-to-back direction is the left-to-right direction.

[0033] like Figure 1 As shown, the horizontal support 10 extends in the front-to-back direction. The vertical support 20 is vertically connected to the front end of the horizontal support 10 and extends in the up-down direction. The vertical support 20 is provided with an output channel 21, which connects to the next workstation. It is worth noting that the next workstation can be an adhesive application station, used for attaching the tab adhesive to the battery tabs; this will not be described in detail here. In other words, the main purpose of the adhesive feeding device of this invention is to output the tab adhesive to the adhesive application station for the adhesive application process.

[0034] like Figure 1 As shown, the guide fork 30 is slidably mounted on the horizontal support 10. Therefore, the guide fork 30 can move back and forth in the horizontal direction to achieve the purpose of outputting the tab adhesive in segments through the output channel 21 to the next station.

[0035] For example, the guide fork 30 has two guide fork teeth 31 arranged vertically at intervals. Each guide fork tooth 31 has a guide groove 32 that extends through both ends of the guide fork 30. The guide groove 32 is used to pass through the tab adhesive. By setting two guide grooves 32 arranged vertically at intervals, two tab adhesives can be fed simultaneously, so that the two tab adhesives can be output to both sides of the battery tabs at the same time for bonding, thereby simplifying the process and improving production efficiency.

[0036] The guide fork 30 has an inlet and an outlet, respectively. For example, in this embodiment, the inlet is at the rear and the outlet is at the front. Each guide groove 32 passes through and connects to both ends of the guide fork 30, so that the tab rubber can enter the guide groove 32 from the inlet of the guide fork 30 and be output from the outlet of the guide fork 30.

[0037] like Figure 1As shown, the guide fork 30 can move along the front-back direction on the horizontal support 10 in the following manner: The glue feeding device also includes a mounting bracket 70 and a power component 80. The mounting bracket 70 is slidably connected to the horizontal support 10. The power component 80 is drivenly connected to the mounting bracket 70 and is used to drive the mounting bracket 70 to reciprocate relative to the horizontal support 10.

[0038] The feed end of the guide fork 30 is fixedly mounted on the mounting support 70. Thus, when the power component 80 drives the mounting support 70 to move back and forth along the horizontal bracket 10, the guide fork 30 can move back and forth together with the mounting support 70.

[0039] like Figure 1 As shown, the discharge end of the guide fork 30 passes through the output channel 21. When the power unit 80 drives the mounting bracket 70 to move forward and causes the guide fork 30 to move forward into position, the discharge end of the guide fork 30 extends along the output channel 21 to the rear of the vertical support, so that the tab rubber can be output to the next station.

[0040] See Figure 1 In one embodiment, a linear slide rail 11 is provided on the horizontal support 10, and a sliding seat 71 is connected to the bottom of the mounting support 70. The sliding seat 71 is slidably connected to the linear slide rail 11. The linear slide rail 11 extends in the front-back direction.

[0041] The power component 80 includes a lead screw 81 and a motor 82. The lead screw 81 is threadedly connected to the sliding seat 71. The motor 82 is connected to one end of the lead screw 81 and is used to drive the lead screw 81 to rotate, so that the sliding seat 71 can move along the length direction of the linear slide rail 11.

[0042] In this embodiment, when the motor 82 drives the lead screw 81 to rotate, the lead screw 81 can drive the sliding seat 71 to move along the length direction of the linear slide rail 11, thereby enabling the sliding seat 71 and the mounting support 70 to reciprocate in the front-back direction on the horizontal support 10. This, in turn, allows the guide fork 30 to reciprocate in the front-back direction, achieving segmented output of the tab rubber. By using the method of driving the lead screw 81 to rotate with the motor 82, combined with the guiding effect of the linear slide rail 11, the accuracy and stability of the front-back reciprocating movement of the guide fork 30 can be improved, thus contributing to improving the output accuracy and stability of the tab rubber.

[0043] Optionally, such as Figure 1As shown, there can be two linear slide rails 11, which are respectively disposed on both sides of the lead screw 81. The two sides of the sliding seat 71 are slidably connected to the two linear slide rails 11 respectively. By setting the two linear slide rails 11 on both sides of the lead screw 81 and making the two sides of the sliding seat 71 slidably connected to the two linear slide rails 11 respectively, the stability of the movement of the sliding seat 71 can be improved, the stability of the movement of the guide fork 30 can be improved, and thus the output stability of the electrode rubber can be improved.

[0044] See Figure 1 As shown, the clamping assembly 40 is connected to the feed end of the guide fork 30. Specifically, the clamping assembly 40 can be fixedly mounted on the mounting bracket 70. When the tab adhesive passes through the guide groove 32, the clamping assembly 40 can clamp the tab adhesive into the corresponding guide groove 32 on the guide fork 30. Thus, when the guide fork 30 moves forward, the tab adhesive can be conveyed forward with the guide fork 30.

[0045] For example, the clamping assembly 40 may include two third driving members 41 and two third pressing blocks 42, with the two third pressing blocks 42 respectively arranged corresponding to the two guide grooves 32. The two third driving members 41 are used to drive the two third pressing blocks 42 to move up and down, so that the third pressing blocks 42 can extend into the guide grooves 32 and press the tab adhesive onto the guide fork 30. The third driving members 41 may be electric push rods or linear cylinders.

[0046] In this embodiment, when the tab adhesive is inserted into the guide groove 32, the upper third pressure block 42 moves downward under the drive of the corresponding third drive member 41 to clamp the tab adhesive onto the guide fork 30. The lower third pressure block 42 moves upward under the drive of the corresponding third drive member 41 to clamp the tab adhesive onto the guide fork 30. Thus, when the guide fork 30 moves forward, the two tab adhesives can be conveyed forward with the guide fork 30. It can be understood that after the guide fork 30 conveys the tab adhesive into place, the guide fork 30 stops moving forward. The two third pressure blocks 42 can release the two tab adhesives respectively, so that the front part of the tab adhesive can be kept in the current position. Then, the guide fork 30 and the adhesive clamping assembly 40 can synchronously reset backward to clamp and convey the next part of the tab adhesive.

[0047] See Figure 2 and Figure 3 The first pressing assembly 50 is mounted on the vertical support 20. The first pressing assembly 50 includes a first driving member 51 and two first pressing blocks 52, which are located between two guide forks 31. The first driving member 51 can drive the two first pressing blocks 52 away from each other so that parts of the two first pressing blocks 52 can respectively extend into the two guide grooves 32, so that each first pressing block 52 can cooperate with the corresponding second pressing block 62 to press and fix the tab adhesive.

[0048] Alternatively, the first driving member 51 can drive the two first pressing blocks 52 to move closer to each other so that the two first pressing blocks 52 exit the two guide grooves 32 respectively, so that each first pressing block 52 can cooperate with the corresponding second pressing block 62 to loosen the tab adhesive.

[0049] Optionally, the first driving component 51 is a parallel pneumatic gripper, and the two first pressure blocks 52 are respectively fixed on the two grippers of the parallel pneumatic gripper. It can be understood that the structure and principle of the parallel pneumatic gripper can refer to the parallel pneumatic grippers in related technologies, as long as it can achieve the purpose of making the two first pressure blocks 52 move away from or closer to each other.

[0050] Alternatively, in other embodiments, the first driving member 51 may also be other forms of clamping driving member, such as a linkage driving mechanism. The goal is simply to achieve the purpose of moving the two first pressing blocks 52 away from or towards each other.

[0051] like Figure 3 As shown, in one embodiment, a first protrusion 53 is provided on the opposing surfaces of the first pressing block 52 and the second pressing block 62. The width of the first protrusion 53 matches the guide groove 32 so that it can extend into the guide groove 32. The first protrusion 53 may be a strip-shaped protrusion or a protruding post, which is used to abut against the corresponding second pressing block 62 to achieve the purpose of pressing and fixing the tab adhesive.

[0052] See Figure 1 and Figure 3 As shown, two second pressing assemblies 60 are mounted on the vertical support 20 and located on the upper and lower sides of the guide fork 30, respectively. Each second pressing assembly 60 includes a second driving member 61 and a second pressing block 62, which are arranged vertically corresponding to the first pressing block 52. The second driving member 61 drives the second pressing block 62 to move closer to or away from the corresponding first pressing block 52, thereby clamping or releasing the electrode tabs. Optionally, the second driving member 61 is a linear cylinder or an electric push rod.

[0053] like Figure 3 As shown, in one embodiment, the second pressing block 62 has a second protrusion 63 on its surface opposite to the first pressing block 52. The width of the second protrusion 63 matches the guide groove 32 so that it can extend into the guide groove 32. The second protrusion 63 can be a strip-shaped protrusion or a protruding post, which is used to abut against the corresponding first pressing block 52 to achieve the purpose of pressing and fixing the tab adhesive.

[0054] In this invention, after the guide fork 30 delivers the tab adhesive to its designated position, the guide fork 30 stops moving forward. At this time, the first drive member 51 can drive the two first pressure blocks 52 to move away from each other, so that the two first protrusions 53 can respectively extend into the two guide grooves 32. Simultaneously, the second drive member 61 located on the upper side of the guide fork 30 can drive the second pressure block 62 to move downward to abut against the upper first pressure block 52 to clamp the tab adhesive. The second drive member 61 located on the lower side of the guide fork 30 can drive the second pressure block 62 to move upward to abut against the lower first pressure block 52 to clamp the tab adhesive. Thus, the first pressure assembly 50 and the two second pressure assemblies 60 can clamp and fix the two tab adhesives, keeping them in their current position for easy processing in the next step. Then, the clamping assembly 40 is released, and the power member 80 can drive the mounting bracket 70 to move backward, achieving synchronous rearward reset of the guide fork 30 and the clamping assembly 40. Then, the clamping assembly 40 can clamp the next section of adhesive strip onto the guide fork 30, which can then convey the next section of adhesive strip forward again. By repeating this process, segmented continuous output of the tab adhesive can be achieved.

[0055] Furthermore, each time the guide fork 30 moves forward to deliver adhesive, the first drive unit 51 can drive the two first pressure blocks 52 to remain in a close-to-each-other position, so that the two first protrusions 53 respectively exit the two guide grooves 32, avoiding the risk of material blockage caused by the first protrusions 53 rubbing against the tab adhesive. And the second drive unit 61 can drive the second pressure block 62 away from the corresponding first pressure block 52, avoiding the risk of material blockage caused by the second protrusions 63 rubbing against the tab adhesive, thereby ensuring that the tab adhesive in the guide groove 32 is smoothly output forward, improving the smoothness and continuity of tab adhesive delivery.

[0056] See Figure 1 In one embodiment, the adhesive feeding device for the tabs further includes a clamping roller assembly 90, which is disposed on the sliding seat 71 and located behind the feed end of the guide fork 30. The clamping roller assembly 90 includes two clamping rollers 91 arranged in pairs, the distance between the two clamping rollers 91 being adjustable, and the two clamping rollers 91 being used to clamp the tabs. For example, the two clamping rollers 91 can be respectively fixed on the two jaws of a parallel pneumatic gripper, so that the distance can be adjusted under the drive of the parallel pneumatic gripper, thereby enabling the two clamping rollers 91 to clamp or release the tabs as needed.

[0057] In this embodiment, by setting up a clamping roller assembly 90, when the two tab rubbers pass between the two clamping rollers 91 and are respectively placed in the two guide grooves 32, the clamping roller assembly 90 can clamp and fix the two tab rubbers, ensuring that the relative positions of the two tab rubbers and the guide fork 30 are fixed. Furthermore, by placing the clamping roller assembly 90 on the sliding seat 71, it can be ensured that the clamping roller assembly 90 and the guide fork 30 can move synchronously back and forth in the front-to-back direction, thereby ensuring that the two tab rubbers can be synchronously conveyed forward with the guide fork 30, improving the synchronous output accuracy of the two tab rubbers.

[0058] In this invention, the glue feeding device first passes two tabs of glue between two clamping rollers 91 and into two guide grooves 32, where the two clamping rollers 91 hold the two tabs of glue in place. Then, the clamping assembly 40 clamps the two tabs of glue firmly into the two guide grooves 32 of the guide fork 30. Simultaneously, the two first pressing blocks 52 of the first pressing assembly 50 are positioned close to each other to avoid obstructing the tabs of glue in the guide grooves 32; the second pressing block 62 of the second pressing assembly 60 is positioned away from the corresponding first pressing block 52 to also avoid obstructing the tabs of glue in the guide grooves 32.

[0059] Then, the power unit 80 drives the sliding seat 71 to move forward, enabling the guide fork 30 to synchronously output the two tab rubbers to the next workstation. Once the guide fork 30 has moved to its designated position, it stops moving forward. At this point, the first drive unit 51 drives the two first pressure blocks 52 to move away from each other, allowing the two first protrusions 53 to extend into the two guide grooves 32 respectively. Simultaneously, the second drive unit 61 drives the second pressure block 62 to move closer to the corresponding first pressure block 52, so that the first pressure block 52 and the second pressure block 62 cooperate to clamp and fix the tab rubbers in the two guide grooves 32 respectively.

[0060] Subsequently, the clamping assembly 40 and the clamping roller group 90 release the tab rubber, and the power component 80 drives the sliding seat 71 to move backward, causing the guide fork 30 and the clamping roller group 90 to move backward and reset synchronously to clamp and fix the next section of tab rubber. Repeating the above process can achieve continuous and synchronous output of the two tab rubbers.

[0061] The electrode adhesive feeding device of this embodiment utilizes the reciprocating motion of the guide fork to convey the electrode adhesive to the next workstation and achieve segmented output of the electrode adhesive. The clamping assembly clamps the electrode adhesive onto the guide fork, allowing it to be conveyed forward along with the guide fork. A first pressing assembly and two second pressing assemblies clamp the electrode adhesive when it reaches its designated position, keeping it fixed in that position. Then, the clamping assembly releases the electrode adhesive, allowing the guide fork to move backward and reset, clamping the next segment of electrode adhesive again, and then conveying the electrode adhesive forward.

[0062] Furthermore, during the forward conveying of the tab rubber by the guide fork, the two first pressing blocks of the first pressing assembly can be positioned close to each other, with neither first pressing block extending into the guide trough. This ensures the tab rubber in the guide trough is smoothly output forward, avoiding the risk of material blockage caused by friction between the first pressing blocks and the tab rubber. Additionally, the second pressing block of the second pressing assembly can be positioned away from its corresponding first pressing block to avoid friction with the tab rubber and subsequent material blockage, thus ensuring the smooth forward output of the tab rubber in the guide trough.

[0063] Therefore, the glue feeding device of this utility model embodiment can not only realize the segmented and continuous output of the tab glue to the next station, but also ensure that the tab glue in the guide trough can be output smoothly, reducing the risk of material blockage during the output process of the tab glue and effectively improving the production efficiency of the tab glue.

[0064] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0065] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
