Description

Technical Field

[0001] This invention relates to the field of new energy technology, and in particular to an adhesive application device and adhesive application equipment. Background Technology

[0002] In current production processes, especially when applying adhesive to battery packs, one or two layers of adhesive are required. Existing adhesive application equipment can only perform a single application method, meaning it can only apply one or two layers of adhesive. However, battery packs require two layers of adhesive on the long side and one layer on the short side. Therefore, current technology necessitates replacing the adhesive application equipment or performing multiple applications, reducing efficiency. Therefore, a new adhesive application device is needed that can apply one layer of adhesive and simultaneously apply two layers. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an adhesive application device capable of applying one layer of adhesive tape and two layers of adhesive tape.

[0031] Reference Figure 1 and Figure 2 The image shows an adhesive applicator according to a first aspect embodiment of the present invention, for applying adhesive tape 500 to a workpiece 300, including an adhesive applicator assembly 110, a switching mechanism 120 and a driving mechanism 130.

[0032] The adhesive application assembly 110 is equipped with a first adhesive application component 111 and a second adhesive application component 112, which are used to apply adhesive to the workpiece 300. Adhesive paper 500 is placed on the first adhesive application component 111 and the second adhesive application component 112 and then adhered to the workpiece 300. Specifically, the adhesive paper 500 has a first side and a second side, where the first side is a smooth surface and the second side is an adhesive surface, with an adhesive substance applied to the second side for adhesion. On the adhesive application platform 113, the first adhesive application component 111 and the second adhesive application component 112 adsorb the adhesive paper 500, causing the smooth surface of the adhesive paper 500 to adhere to the first adhesive application component 111 and the second adhesive application component 112. By driving the adhesive application assembly 110 to move, the first adhesive application component 111 and the second adhesive application component 112 press the adhesive paper 500 onto the workpiece 300, thereby applying adhesive to the workpiece 300.

[0033] The switching mechanism 120 drives the first adhesive applicator 111 to switch between a clearance state and an adhesive applicator state. In the adhesive applicator state, the first adhesive applicator 111 applies adhesive to the workpiece 300; in the clearance state, the first adhesive applicator 111 stops applying adhesive to the workpiece 300. The second adhesive applicator 112 is fixed in the adhesive applicator state to apply adhesive to the workpiece 300. When two layers of adhesive tape 500 need to be applied, the first adhesive applicator 111 switches to the adhesive applicator state and applies adhesive together with the second adhesive applicator 112. In this case, the adhesive applicator assembly 110 can apply two layers of adhesive tape 500 to the workpiece 300 in one adhesive applicator stroke. When a layer of adhesive tape 500 needs to be applied, the first adhesive applicator 111 switches to a clearance state. In this clearance state, no adhesive is applied to the workpiece 300. That is, during the adhesive application stroke of the adhesive application platform 113, by moving the first adhesive applicator 111 to the clearance state, the first adhesive applicator 111 and the adhesive tape 500 on it will not come into contact with the workpiece 300, thus preventing the adhesive tape 500 from being applied to the workpiece 300. At this time, only the second adhesive applicator 112 performs the adhesive application work to form a layer of adhesive tape 500. The clearance state is... Figure 1 The position of the first adhesive-applying component 111. In the adhesive-applying state, the first adhesive-applying component 111 and the second adhesive-applying component 112 are flush. The first adhesive-applying component 111 is rotated to... Figure 1 The avoidance state in the middle.

[0034] like Figure 7 As shown, the drive mechanism 130 is used to drive the adhesive application assembly 110 to move. The drive mechanism 130 drives the adhesive application assembly 110 to move, thereby completing the entire adhesive application stroke. Specifically, the drive mechanism 130 first drives the adhesive application assembly 110 to move, so that the second adhesive application component 112 and the first adhesive application component 111 in the adhesive application state move below the workpiece 300. When they move below the workpiece 300, the drive mechanism 130 drives the second adhesive application component 112 and the first adhesive application component 111 in the adhesive application state to move vertically towards the workpiece 300, so that the adhesive tape 500 is pasted on the workpiece 300, and the adhesive tape 500 is pressed to make the adhesive tape 500 adhere more tightly. After the adhesive tape 500 is attached to the workpiece 300, the drive mechanism 130 drives the adhesive application assembly 110 to move away from the workpiece 300 along the length of the adhesive tape 500, causing the second adhesive application component 112 and the first adhesive application component 111 (in the adhesive application state) to move away from below the workpiece 300, simultaneously causing the adhesive tape 500 to adhere to the bottom of the workpiece 300. After moving away from below the workpiece 300, the drive mechanism 130 drives the adhesive application assembly 110 to move vertically, causing the adhesive tape 500 to be attached to the side of the workpiece 300. After the side is attached, it moves closer to the workpiece 300 along the length of the adhesive tape 500 above the workpiece 300, causing the adhesive tape 500 to be attached to the top of the workpiece 300. At this point, one adhesive application cycle is completed. During the adhesive application process, when the drive mechanism 130 drives the adhesive application assembly 110 to move, it also drives the adhesive tape 500 to move, causing the adhesive tape 500 to be attached to the workpiece 300 via the first adhesive application component 111 and the second adhesive application component 112.

[0035] It should be noted that when the first adhesive-applying component 111 is in the adhesive-applying state, the adhesive-applying method of the first adhesive-applying component 111 to the workpiece 300 is similar to the adhesive-applying method of the second adhesive-applying component 112 described above.

[0036] Furthermore, rollers can be provided on the first adhesive applicator 111 and the second adhesive applicator 112. The rollers firstly reduce the friction between the adhesive tape 500 and the first and second adhesive applicators 111 and 112, especially when applying adhesive to the sides and top of the workpiece 300, where significant friction can occur. Secondly, the rollers can roll and press the adhesive tape 500, resulting in a tighter bond. Especially with rollers made of flexible materials, rolling pressure can be applied effectively without damaging the adhesive tape 500. Specifically, the second adhesive applicator 112 is horizontal, and the adhesive tape 500 is placed horizontally on and adsorbed by it. When applying the adhesive tape 500 to the bottom surface of the workpiece 300, the front of the adhesive tape 500 is pressed against the bottom surface of the workpiece 300, and the adhesive tape 500 is pressed again when the bottom of the workpiece 300 is removed. After passing the bottom surface of workpiece 300, the rollers continue to press the adhesive tape 500 onto the sides and top surface of workpiece 300. When the rollers are applying the tape to the side, the angle between the moving direction of the adhesive tape 500 and the application direction is 90°, which creates some friction. The rollers greatly reduce this frictional resistance, protecting the adhesive tape 500. Simultaneously, when applying the tape to the top of workpiece 300, the angle between the moving direction of the adhesive tape 500 and the application direction is 180°, requiring even more protection from the rollers. Furthermore, a color mark sensor 180 can be installed on the tape application assembly 110 to detect whether the adhesive tape 500 is properly applied to workpiece 300, preventing missed applications.

[0037] like Figure 2As shown, the adhesive application assembly 110 also includes an adhesive application platform 113, which is connected to the drive mechanism 130. The first adhesive application component 111 and the second adhesive application component 112 are both connected to the adhesive application platform 113. The drive mechanism 130 includes a first linear module 131 and a second linear module 132. The first linear module 131 drives the adhesive application platform 113 to move in a first direction, and the second linear module 132 drives the adhesive application platform 113 to move in a second direction. The first direction is the projection direction of the length of the adhesive tape 500 onto the horizontal plane, and the second direction is the vertical direction. The drive mechanism 130 controls the adhesive application platform 113 to move in both directions, thereby completing the adhesive application work. First, the second linear module 132 is used to lower the second adhesive applicator 112 below the bottom of the workpiece 300. Then, the first linear module 131 is used to extend the second adhesive applicator 112 into the bottom of the workpiece 300. After entering below the bottom, the second linear module 132 drives the second adhesive applicator 112 to press the adhesive tape 500 onto the bottom of the workpiece 300. After the adhesive tape 500 is applied to the bottom of the workpiece 300, the first linear module 131 drives the second adhesive applicator 112 outward, away from the workpiece 300. At this time, the roller rolls on the workpiece 300 to the junction of the bottom and side surfaces. Then, the second linear module 132 drives the adhesive application platform 113 upward, causing the roller to roll to the junction of the side and top surfaces of the workpiece 300. Finally, the first linear module 131 drives the roller to roll on the top of the workpiece 300 to apply the adhesive. One adhesive application cycle is completed after the top of workpiece 300 is coated with adhesive.

[0038] like Figure 2 As shown, the drive mechanism 130 also includes a third linear module 133, which drives the adhesive application platform 113 to move upward in a third direction, which is a direction perpendicular to the first direction on a horizontal plane. When applying adhesive to the workpiece 300, it is usually necessary to apply the adhesive tape 500 to the middle position or a specific position of the workpiece 300. In order to ensure the accuracy of the position of the adhesive tape 500 on the workpiece 300 during adhesive application, the third linear module 133 is used to adjust the relative position of the adhesive tape 500 on the workpiece 300.

[0039] like Figure 6As shown, the adhesive applicator 100 also includes a first retraction mechanism 140, which retracts the adhesive tape 500 after the adhesive application is completed. After the adhesive application is completed, a portion of the adhesive tape 500 extends beyond the first adhesive part 111, i.e., the adhesive tape 500 extends beyond the workpiece 300. This excess portion cannot be stably adhered to the workpiece 300 during the next adhesive application, which affects the quality of the adhesive application and wastes the adhesive tape 500. Therefore, the first retraction mechanism 140 retracts the extended excess adhesive tape 500, which improves the adhesive application quality and avoids the waste of the adhesive tape 500. Specifically, the first retraction mechanism 140 includes a first movable roller 141, a first fixed roller 143, and a first driving member 142. The first movable roller 141 and the first fixed roller guide the conveying path of the adhesive tape 500. The first driving member 142 drives the first movable roller 141 to move, thereby changing the length of the conveying path of the adhesive tape 500 between the first movable roller 141 and the first fixed roller 143. When it is necessary to retract the adhesive tape 500, the first driving member 142 drives the first movable roller 141 to move, causing the conveying path of the adhesive tape 500 to lengthen, thereby causing the adhesive tape 500 on the first adhesive applicator 111 or the second adhesive applicator 112 to retract. The second retraction mechanism is the same as the first retraction mechanism 140, including two second fixed rollers and a second movable roller, and retracts in the same manner.

[0040] like Figure 1 As shown, the switching mechanism 120 is a telescopic cylinder 121, which is mounted on the adhesive application platform 113. The telescopic end of the telescopic cylinder 121 is connected to the first adhesive application component 111, which is rotatably connected to the adhesive application platform 113. The retraction of the telescopic cylinder 121 drives the first adhesive application component 111 to switch to the avoidance state. The rotation of the first adhesive application component 111 on the adhesive application platform 113 is controlled by the extension and retraction of the telescopic cylinder 121. When the telescopic cylinder 121 retracts, the first adhesive application component 111 rotates downward, stopping the adhesive application and avoiding interference with the workpiece 300 when the second adhesive application component 112 is applying adhesive. By using rotation to switch between the avoidance state and the adhesive application state, the influence of the first adhesive application component 111 on the adhesive paper 500 during the position switching is minimized. The axial direction of the rotation axis of the first adhesive application component 111 is the width direction of the adhesive paper 500, i.e., the third direction.

[0041] like Figure 1As shown, the adhesive application platform 113 is also equipped with an adhesive removal mechanism 150. The adhesive removal mechanism 150 is used to pull the adhesive tape 500 out of the film roll 400, and the adhesive tape 500 is wound into the film roll 400. Specifically, the film roll 400 is rotatably mounted on the adhesive application device 100. The adhesive tape 500 is pulled out from the film roll 400 and placed on the adhesive application platform 113 for adhesive application. When pulling out the adhesive tape 500, due to the large resistance, the adhesive tape 500 may slip on the adhesive application platform 113, making it impossible to pull out. By using the adhesive removal mechanism 150 to pull the adhesive tape 500 out of the film roll 400 in advance, and using the adhesive tape 500 pulled out by the adhesive removal mechanism 150 during adhesive application, the resistance of the adhesive tape 500 during adhesive application on the adhesive application platform 113 is greatly reduced. The specific adhesive release mechanism 150 includes a clamping member and a second driving member. The clamping member clamps the adhesive paper 500 and is driven by the second driving member to pull out the adhesive paper. After being pulled out, the adhesive paper 500 is released and reset.

[0042] According to some embodiments of the present invention, both the first adhesive applicator 111 and the second adhesive applicator 112 are provided with a cutter for cutting the adhesive tape 500. Cutting the adhesive tape 500 with the cutter after adhesive application ensures a neat cut surface and facilitates subsequent adhesive application. Specifically, as... Figure 5 As shown, the cutter can employ a sliding blade positioned below the adhesive application platform 113. After adhesive application is completed, the blade extends and cuts the adhesive tape 500 between the workpiece 300 and the adhesive application platform 113. Alternatively, the first adhesive application component 111 may also include a first end face 162 capable of contacting the adhesive tape 500. The first cutter 160 includes a first cutting head 161, which can extend from the first end face 162 and retract from the first end face 162 into the interior of the first adhesive application component 111. It should be noted that... Figure 5 In the middle, the adhesive tape 500 has retracted and is located on the top surface of the first adhesive part 111; please refer to... Figure 5 and Figure 7 During the application of adhesive, a portion of the adhesive tape 500 will cover the first end face 162. Both the top surface of the first adhesive application component 111 and the first end face 162 may be provided with adsorption holes for adsorbing the adhesive tape 500.

[0043] If the cutter provided on the second adhesive applicator 112 is referred to as the second cutter, then the mating relationship between the second adhesive applicator 112 and the second cutter is similar to the mating relationship between the first adhesive applicator 111 and the first cutter. The second adhesive applicator 112 also includes a second end face capable of contacting the adhesive paper. The second cutter includes a second blade that can extend from and retract from the second end face into the interior of the second adhesive applicator 112. When the second blade extends from the second end face, it cuts the adhesive paper 500 at the second end face. Both the top surface and the second end face of the second adhesive applicator 112 may be provided with adsorption holes for adsorbing the adhesive paper 500.

[0044] like Figure 1 As shown, the adhesive application platform 113 is also equipped with a pressing mechanism 170. The pressing mechanism 170 fixes the adhesive paper 500 onto the adhesive application platform 113 when the cutter 160 cuts the adhesive paper 500. During the cutting process, the adhesive paper 500 is pulled outwards under pressure, resulting in more excess adhesive paper and affecting the cutting effect, preventing complete cutting or creating an uneven cut. Specifically, the pressing mechanism 170 includes a pressing head and a third driving component. The third driving component drives the pressing head to move, pressing the adhesive paper 500 onto the first adhesive application component 111 or the second adhesive application component 112, preventing further conveying of the adhesive paper 500 and ensuring successful cutting. Furthermore, the pressing mechanism 170 also fixes the adhesive paper 500 during the de-adhesion process to ensure completion of the de-adhesion.

[0045] Figure 3 The adhesive application apparatus of the present invention is shown. According to a second aspect embodiment of the present invention, the adhesive application apparatus includes a plurality of adhesive application devices 100 as described in any of the above embodiments; a plurality of clamps 210, each clamp corresponding to one of the adhesive application devices 100. The clamps 210 are used to hold the workpiece 300 to be adhesively applied. Each clamp 210 is provided with a rotating mechanism 220 for rotating the clamp 210 to adjust the adhesive application position of the workpiece 300. Using multiple clamps 210 and multiple adhesive application devices 100 for adhesive application greatly increases the adhesive application efficiency on the workpiece 300. Simultaneously, the clamps 210 control the adhesive application position of the adhesive application devices 100 on the workpiece 300 by rotation, thereby achieving comprehensive adhesive application to the workpiece 300.

[0046] Reference Figure 4 According to some embodiments of the present invention, a clamping platform 230 is included, and a plurality of clamps 210 are disposed on the clamping platform 210. A fourth linear module 240 is disposed on the clamping platform 230. The fourth linear module 240 is used to drive the clamping platform 230 to move along a first direction to adjust the distance between the workpiece 300 and the adhesive application platform 113. By adjusting the relative distance between the workpiece 300 and the adhesive application platform 113 through the movement of the fourth linear module 240, it is possible to accommodate workpieces 300 of different sizes for adhesive application, and at the same time, the adhesive application length on the workpiece 300 can be adjusted, that is, the adhesive application length on the workpiece 300 can be reduced by moving the workpiece 300 away from the adhesive application device 100.
