Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and specifically relates to a battery tab adhesive application device. Background Technology

[0002] In battery manufacturing, battery tabs are crucial components connecting the internal electrodes to the external circuitry, and their welding and encapsulation quality directly impacts battery safety and lifespan. Ultrasonic welding, with its advantages of high efficiency and no solder contamination, has become the mainstream process for connecting battery tabs to busbars. After ultrasonic welding, the battery tabs must be coated with adhesive to protect the welded areas from mechanical damage, electrolyte corrosion, and to prevent short-circuit risks.

[0003] Current battery tab bonding devices are prone to tearing the tabs during the bonding process, resulting in a high defect rate in battery production. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a battery tab adhesive application device that can effectively avoid tearing of the battery tabs during the adhesive application process, thereby improving the yield rate in the battery production process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A battery tab adhesive applicator includes an actuator, a support mechanism, and adhesive applicator heads. There are two adhesive applicator heads mounted on the support mechanism, and the support mechanism is connected to the actuator.

[0007] The adhesive applicator mechanism includes at least a drive assembly and an adhesive applicator assembly. The drive assembly is fixed to the support mechanism and connected to the adhesive applicator assembly. The adhesive applicator assembly has a plurality of adhesive tape adsorption holes for adsorbing adhesive tape.

[0008] The support mechanism is connected to the actuator. The actuator can drive the adhesive head assembly to move horizontally to the tape placement position and the adhesive application position through the support mechanism to adsorb the tape. The drive assembly can drive the adhesive head assembly to move vertically to stick the adsorbed tape onto the battery.

[0009] When the two adhesive applicator assemblies adsorb the adhesive tape, they are positioned at a high position and a low position, respectively, so that the two ends of the adsorbed adhesive tape form a high end portion and a low end portion. The high end portion is used to adhere to the surface of the battery, and the low end portion is used to adhere to the battery tabs.

[0010] As can be seen from the above technical solutions, the battery tab adhesive device disclosed in this utility model embodiment has a height difference between the battery surface and the tab. Therefore, when the two adhesive head components are positioned at a high position and a low position respectively when adsorbing the adhesive tape, the battery surface and the tab can be adhesively applied at the same time in one go, avoiding the tab tearing during the adhesive application process, thereby improving the yield in the battery production process.

[0021] In view of this, the purpose of this utility model is to provide a battery tab adhesive application device, which can avoid tearing of the battery tabs during the adhesive application process, thereby improving the yield in the battery production process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Please refer to... Figures 1 to 7 .

[0023] Please refer to Figure 1 and Figure 2 The battery tab adhesive applicator disclosed in this embodiment includes an actuator 100, a support mechanism 200, and adhesive applicator head mechanisms 300. Two adhesive applicator head mechanisms 300 are mounted on the support mechanism 200, which is connected to the actuator 100. Each adhesive applicator head mechanism 300 includes at least a drive assembly 301 and an adhesive applicator head assembly 302. The drive assembly 301 is fixed to the support mechanism 200 and connected to the adhesive applicator head assembly 302. The adhesive applicator head assembly 302 has multiple adhesive tape adsorption holes 3022a for adsorbing adhesive tape. The support mechanism 200 is connected to the actuator 100. The actuator 100 can drive the adhesive applicator head assembly 302 to move horizontally to the tape placement position and the adhesive application position via the support mechanism 200 to adsorb the adhesive tape. The drive assembly 301 can drive the adhesive applicator head assembly 302 to move vertically to adhere the adsorbed adhesive tape to the battery.

[0024] The two adhesive applicator assemblies 302 are positioned at a high position and a low position respectively when adsorbing the adhesive tape, so that the two ends of the adsorbed adhesive tape form a high end and a low end. The high end is used to stick to the surface of the battery 500, and the low end is used to stick to the tab of the battery 500.

[0025] When applying adhesive to the battery tabs, the actuator 100 is first activated, which drives the support mechanism 200 to operate. The support mechanism 200 then drives the adhesive application head assembly 302 to the tape placement position to absorb the tape. Since the two adhesive application head assemblies 302 are in high and low positions respectively when absorbing the tape, the two ends of the tape absorbed by the two adhesive application head assemblies 302 form a high end and a low end. Then, the actuator 100 is activated again, and the actuator 100 drives the adhesive application head assembly 302 to the application position through the support mechanism 200. At this time, the drive assembly 301 is activated, and the drive assembly 301 drives the adhesive application head assembly 302 to move downward in the vertical direction, attaching the high end of the tape to the surface of the battery and attaching the low end of the tape to the battery tabs. At this time, the adhesive application is completed.

[0026] The battery tab applicator disclosed in this embodiment of the invention has a height difference between the surface of the battery 500 and the tab. Therefore, when applying the adhesive, the two applicator head assemblies 302 are positioned at a high position and a low position respectively when adsorbing the adhesive tape. This allows the surface of the battery 500 and the tab to be applicated simultaneously in one go, avoiding tearing of the tab during the applicator process and thus improving the yield rate in the battery production process.

[0027] Please refer to Figure 5 and Figure 7 The adhesive applicator assembly 302 disclosed in this embodiment of the present invention includes an adhesive applicator body 3021 and an adhesive applicator adsorption part 3022. The adhesive applicator body 3021 has a vacuum adsorption channel, the adhesive applicator adsorption part 3022 is disposed on the adhesive applicator body 3021 and is connected to the vacuum adsorption channel, and the adhesive tape adsorption hole 3022a is disposed on the adhesive applicator adsorption part 3022.

[0028] Please refer to Figure 6 The vacuum adsorption channel includes an inlet end 3021a and an outlet end 3021b. The inlet end 3021a is connected to a negative pressure fan, and the adhesive applicator adsorption part 3022 is connected to the outlet end 3021b. When the negative pressure fan is turned on, the adhesive tape adsorption holes 3022a on the adhesive applicator adsorption part 3022 can adsorb the adhesive tape onto the adhesive applicator adsorption part 3022 under the action of the negative pressure fan.

[0029] This embodiment of the invention does not limit the specific shape of the two adhesive applicator bodies 3021. The two adhesive applicator bodies 3021 can have the same shape or different shapes, as long as they can achieve the function of applying adhesive.

[0030] For ease of processing and manufacturing, the two adhesive applicator bodies 3021 disclosed in this embodiment of the present invention have the same shape and are both rectangular structures.

[0031] This embodiment of the invention does not limit the specific structure of the two adhesive head adsorption parts 3022. Any structure that meets the usage requirements of this invention is within the protection scope of this invention.

[0032] As one embodiment, the two adhesive head adsorption parts 3022 disclosed in this utility model embodiment have the same structure.

[0033] Specifically, both adhesive applicator adsorption parts 3022 are planar adsorption plates, and the two adsorption plates are respectively set on the bottom end face of the adhesive applicator body 3021. A filler plate is provided between the two adhesive applicator bodies 3021. One side of the filler plate is fixed to one adhesive applicator body 3021, and the other side abuts against the other adhesive applicator body 3021.

[0034] This configuration enables standardized mass production of the adsorption plate. The filler plate between the two adhesive applicator bodies 3021 fills the gap between them. As a result, during the adhesive absorption process, the adhesive tape only has two flat surfaces: the upper and lower ends. This improves the flatness of the adhesive surface and prevents wrinkles caused by the gap between the two adhesive applicator bodies 3021 during adhesive absorption.

[0035] As another embodiment, the adhesive applicator 3022 of the two adhesive applicator mechanisms 300 disclosed in this utility model embodiment has different structures.

[0036] Specifically, one adhesive applicator adsorption part 3022 is a planar adsorption plate, and the other adhesive applicator adsorption part 3022 is an L-shaped adsorption plate. The L-shaped adsorption plate includes a horizontal end and a vertical end. The horizontal end is located on the bottom surface of the adhesive applicator body 3021, and the vertical end is located on the side of the adhesive applicator body 3021 and abuts against the other adhesive applicator body 3021.

[0037] This design allows the gap between the two adhesive applicator bodies 3021 to be filled while the adsorption plate is being installed, thereby improving the flatness of the adhesive surface and preventing wrinkles from forming during adhesive absorption due to the gap between the two adhesive applicator bodies 3021.

[0038] This embodiment of the utility model does not specifically limit whether the planar adsorption plate or the L-shaped adsorption plate is installed on the high-positioned or low-positioned adhesive applicator assembly 302. Those skilled in the art can choose to install it according to actual needs.

[0039] In this embodiment of the present invention, the height difference between the adhesive applicator assembly 302 placed at a high position and the adhesive applicator assembly 302 placed at a low position is 2mm-20mm. For example, it can be any value among 2mm, 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm or 2mm-20mm.

[0040] As a further embodiment, the height difference between the adhesive applicator assembly 302 placed at a high position and the adhesive applicator assembly 302 placed at a low position disclosed in this utility model embodiment is 5mm-15mm. For example, it can be any value among 5mm, 8mm, 10mm, 12mm, 15mm or 5mm-15mm.

[0041] As a further embodiment, in the battery tab adhesive applicator disclosed in this utility model embodiment, the adhesive applicator assembly 302 positioned at a higher position has a greater adsorption force than the adhesive applicator assembly 302 positioned at a lower position. With this configuration, the adhesive applicator assembly 302 positioned at a higher position can simultaneously adhere to the surface of the battery 500 with a greater adsorption force and press firmly against the surface of the battery 500, thereby reducing stress damage to the battery 500 caused by the pressing force of the adhesive applicator assembly 302.

[0042] As a specific embodiment of this utility model, the suction force of the negative pressure fan connected to the high-position adhesive head assembly 302 can be set to be greater than that of the negative pressure fan connected to the low-position adhesive head assembly 302.

[0043] For another specific embodiment of this utility model, please refer to the following: Figure 7 The suction force of the negative pressure fan connected to the two adhesive head assemblies 302 can be set to the same suction force, and the number of tape suction holes 3022a of the adhesive head suction part 3022 of the adhesive head assembly 302 placed at the high position can be set to be more than the number of tape suction holes 3022a of the adhesive head suction part 3022 of the adhesive head assembly 302 placed at the low position.

[0044] For example, in this embodiment of the present invention, the tape adsorption holes 3022a of the tape adsorption part 302 ...

[0045] As a further embodiment, please refer to Figure 3 and Figure 4The adhesive applicator 300 disclosed in this embodiment of the present invention further includes an elastic pressing component 303 and a sliding plate 304. The sliding plate is connected to the driving component 301, and the elastic pressing component 303 is connected to the sliding plate 304. The driving component 301 drives the elastic pressing component 303 to move in the vertical direction through the sliding plate 304.

[0046] The drive component 301 can be a linear motor, a linear cylinder, or other structures, as long as it can achieve linear motion. Those skilled in the art can choose according to actual needs.

[0047] Specifically, the sliding plate 304 is connected to the sliding part of the linear motor. When the linear motor is started, the linear motor drives the sliding plate 304 to move up and down in the vertical direction through the sliding part, thereby driving the elastic pressing component 303 to move up and down in the vertical direction.

[0048] As a further embodiment, please refer to the specific details. Figure 4 The elastic pressing assembly 303 disclosed in this embodiment of the present invention includes a top plate 3031, a support column 3032, a spring 3033 and a pressure plate 3034. The top plate 3031 is fixed on the sliding plate. One end of the support column 3032 is fixedly connected to the top plate 3031, and the other end is slidably engaged with the pressure plate 3034. The spring 3033 is sleeved on the support column 3032.

[0049] The drive assembly 301 drives the adhesive applicator assembly 302 to move vertically. When the adhesive applicator assembly 302 comes into contact with the battery 500, the top plate 3031 and the support column 3032 are buffered by the spring 3033 to avoid stress damage to the battery 500.

[0050] As a further embodiment, the elastic clamping assembly 303 disclosed in this utility model embodiment also includes a limiting post 3032, which is fixed to the pressure plate 3034, and the length of the limiting post 3032 is less than the maximum distance between the top plate 3031 and the pressure plate 3034. With this configuration, when the top plate 3031 abuts against the limiting post 3032, the displacement distance of the pressure plate 3034 can be limited.

[0051] As a further embodiment, the adhesive applicator 300 disclosed in this utility model embodiment also includes a correction component, wherein the correction component 305 includes a slide rail 3051 and a slider 3052, the slide rail 3051 is fixed on the sliding plate 304, the slider 3052 is fixed on the pressure plate 3034, and the slide rail 3051 and the slider 3052 are slidably connected.

[0052] Due to design precision deviations, the pressure plate 3034 may become skewed when moving downwards. The setting of the correction component 305 allows the slider 3052 to drive the pressure plate 3034 to move in a directional manner along the slide rail 3051, thereby ensuring the accuracy of the adhesive application position of the adhesive application head component 302.

[0053] To enhance the overall strength of the adhesive applicator mechanism 300, the adhesive applicator mechanism 300 disclosed in this embodiment of the invention further includes an auxiliary support member 306. The auxiliary support member 306 includes a first support plate 3061 and a second support plate 3062 connected vertically. The first support plate 3061 is connected to the pressure plate 3034, and the second support plate 3062 is connected to the adhesive applicator assembly 302. This arrangement forms an L-shaped structure with the first support plate 3061 and the second support plate 3062 connected together.

[0054] As a further embodiment, the auxiliary support 306 disclosed in this utility model embodiment also includes a reinforcing plate 3063, wherein the reinforcing plate 3063 is disposed at the connection between the first support plate 3061 and the second support plate 3062, thereby further improving the strength of the auxiliary support 306, and thus further improving the strength of the entire adhesive applicator mechanism 300.

[0055] As a further embodiment, please refer to... Figure 1 The battery tab adhesive applicator disclosed in this embodiment of the invention further includes a battery placement mechanism 400, wherein the battery placement mechanism 400 includes a battery placement plate 401 and limiting plates 402, and there are at least two limiting plates 402, which are respectively disposed on both sides of the battery placement plate 401. With this arrangement, the battery 500 to be adhesively applied can be placed on the battery placement plate 401 and positioned by the limiting plates 402 on both sides.
