[0032] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1-3 As shown, one embodiment of the present application provides an adhesive application device 1, which includes a base frame 2, an unwinding mechanism 3, an adhesive application mechanism 4, and a drive assembly 5. The unwinding mechanism 3, the adhesive application mechanism 4, and the drive assembly 5 are all mounted on the base frame 2. The unwinding mechanism 3 is used to release the roll of adhesive formed by winding the adhesive to the adhesive application mechanism 4. The adhesive application mechanism 4 is used to adhere the adhesive released by the unwinding mechanism 3 to the surface of the workpiece to be processed. The drive assembly 5 is used to drive the adhesive application mechanism 4 to guide the adhesive released by the unwinding mechanism 3 to be transported along a preset trajectory, and to drive the adhesive application mechanism to collect the film of the adhesive after use.

[0034] It should be understood that the adhesive includes an adhesive body and a film. The film is bonded to the adhesive surface of the adhesive body to prevent the adhesive surface of the adhesive body from sticking to the adhesive applicator 4 during the delivery of the adhesive. During bonding, the adhesive body and the film need to be separated to expose the adhesive surface. In this embodiment, the adhesive is a foam tape, which includes a foam body and release paper bonded to the adhesive surface of the foam body.

[0035] The base frame 2 can be of any shape. In this embodiment, the base frame 2 includes a top plate 21, a bottom plate 23, and two oppositely arranged side plates 22. The two ends of the two side plates 22 are respectively connected to the top plate 21 and the bottom plate 23. The bottom plate 23 is provided with a discharge port 201. The two side plates 22 are connected to the material roll assembly 31. The bottom plate 23 can extend in a direction away from the top plate 21 to form a mounting plate. The mounting plate is used to install the adhesive applicator 4. Since the shape of the base frame 2 can be arbitrarily deformed, for ease of description, the adhesive applicator being installed on the mounting plate will be uniformly described as being installed on the base frame 2 in the following description.

[0036] In some embodiments, please combine Figure 2 and Figure 3The unwinding mechanism 33 includes a roll assembly 31 and a guide roller assembly 32. The roll assembly 31 is used to mount the roll formed by the bonding component, and the guide roller assembly 32 is used to guide the roll of material out from the discharge port 201 of the base frame 2.

[0037] In some embodiments, the roll assembly 31 includes a rotating shaft 311, a first baffle 312, and a second baffle 313. Both ends of the rotating shaft 311 are rotatably mounted on the base frame 2. The first baffle 312 and the second baffle 313 are spaced apart from the rotating shaft 311, and the space between the first baffle 312 and the second baffle 313 is used to accommodate the roll. The first baffle 312 and the second baffle 313 are used to limit the movement of the roll. Both ends of the rotating shaft 311 may be mounted on the base frame 2 via bearing seats, which are fixedly mounted on the base frame 2.

[0038] Furthermore, the coil assembly 31 also includes two support seats 314, which are spaced apart from the rotating shaft 311 and are used to support the inner cylinder of the coil. That is, when the coil is installed in the coil assembly 31, the two support seats 314 are embedded in the inner cylinder of the coil to support it, preventing the coil from tilting relative to the central axis of the rotating shaft 311 due to a large difference between the inner cylinder size and the rotating shaft 311, thus facilitating stable release of the coil. In this embodiment, the support seat 314 is frustum-shaped, and its outer diameter is the same as the inner diameter of the inner cylinder of the coil.

[0039] In some embodiments, the guide roller assembly 32 includes a roller 321 and two guide rollers 322 disposed on the roller 321. The roller 321 is rotatably mounted on the base frame 2, and the two guide rollers 322 are spaced apart on the roller 321. The two guide rollers 322 are used to prevent the released material from moving arbitrarily. In this embodiment, the roller 321 is connected to the base frame 2 via bearings, and the opposite side of the two guide rollers 322 is shaped like a frustum, which helps guide the material to shift towards the middle position of the two guide rollers 322.

[0040] Furthermore, along the material conveying path of the roll, the distance between the two guide rollers 322 on the roller 321 that is closer to the discharge port 201 is smaller. This helps to gradually limit the range of roll offset, allowing the roll to exit along the designated discharge port 201. In this embodiment, along the direction from the top plate 21 toward the bottom plate, the distance between the two guide rollers 322 on the roller 321 that is closer to the bottom plate is smaller, and there are four rollers 321. With the bottom plate as a reference, the guide rollers 322 on the two rollers 321 closest to the bottom plate are triangularly distributed with the discharge port 201, that is, the discharge port 201 is exactly located in the middle of every two guide rollers 322.

[0041] In some embodiments, the unwinding mechanism 3 further includes a plurality of limiting rods 33, which are mounted on the base frame 2 along a direction perpendicular to the central axis of the roller 321. The gap between the roller 321 and the limiting rod 33 is greater than the thickness of the roll material. This helps reduce the risk of the roll material bending and knotting when conveyed toward the discharge port 201, and avoids jamming of the roll material during conveying. In this embodiment, each roller 321 is provided with a limiting rod 33 at adjacent positions to ensure smooth conveying of the roll material. It should be understood that the limiting rod 33 and the roller 321 being at the same horizontal height means that the same reference object, such as a base plate, is selected, and the distance between the central axis of the limiting rod 33 and the central axis of the roller 321 and the base plate is the same.

[0042] In some embodiments, to ensure stable transport of the material roll, the unwinding mechanism 3 further includes a transmission assembly 34 and a magnetic damper 35. The magnetic damper 35 is connected to the transmission assembly 34, which is connected to the rotating shaft 311. Due to the action of the magnetic damper 35, the rotating shaft 311 also exhibits a damping effect, reducing the risk of inertial rotation of the material roll on the rotating shaft 311. In this embodiment, the transmission assembly 34 includes a first transmission wheel 341, a second transmission wheel 342, and a transmission belt 343. The transmission belt 343 is sleeved on the first transmission wheel 341 and the second transmission wheel 342. The first transmission wheel 341 is connected to the output shaft of the magnetic damper 35, and the second transmission wheel 342 is connected to the rotating shaft 311. Under the action of the transmission belt 343, the first transmission wheel 341 and the second transmission wheel 342 rotate synchronously, thereby causing the output shaft of the magnetic damper 35 to rotate or stop synchronously with the rotating shaft 311.

[0043] It should be understood that the structure of the transmission assembly 34 is not limited to the first transmission wheel 341, the second transmission wheel 342, and the transmission belt 343 described above; it can also be other structures, as long as it can achieve synchronous rotation between the rotating shaft 311 and the magnetic damper 35. For example, the transmission assembly 34 can also be composed of a first sprocket, a second sprocket, and a chain.

[0044] In some embodiments, the unwinding mechanism 3 further includes an adjusting component 36, which is mounted on the rotating shaft 311 and located on one side of the first baffle 312. The adjusting component 36 is used to adjust the position of the first baffle 312 on the rotating shaft 311 so that the first baffle 312 presses against the material roll. In this embodiment, the adjusting component 36 includes a spring 361, a sleeve 362, and a locking component 363. The sleeve 362 is sleeved on the rotating shaft 311, the spring 361 is sleeved on the sleeve 362, the first baffle 312 is engaged with the sleeve 362 and abuts against the spring 361, and the locking component 363 is mounted on the sleeve 362. When the locking component 363 is tightened, the sleeve 362 and the rotating shaft 311 are relatively fixed; when the locking component 363 is loosened, the sleeve 362 and the rotating shaft 311 are unlocked, and the sleeve 362 and the rotating shaft 311 can move relative to each other.

[0045] Furthermore, the sleeve component 362 includes a first limiting part 3621, a sleeve body 3622, and a second limiting part 3623. Both the first limiting part 3621 and the second limiting part 3623 extend from the end of the sleeve body 3622 in a direction away from the outer surface of the sleeve body 3622. That is, the end of the sleeve body 3622 extends along a direction away from the central axis of the sleeve body 3622 to form the first limiting part 3621 and the second limiting part 3623. A first stop plate 312 is sleeved on the sleeve body 3622, and a spring 361 is sleeved on the sleeve body 3622 and positioned between the first limiting part 3621 and the first stop plate 312. The first limiting part 3621 has a threaded hole, and a locking member 363 is screwed into the threaded hole. Tightening the locking member 363 locks or releases the sleeve body 3622 and the rotating shaft 311. During installation, the second limiting part 3623 is housed in the inner cylinder of the material roll, and the first baffle 312 abuts against the side end of the material roll. Under the action of the spring 361, the first baffle 312 and the second baffle 313 together clamp the material roll, ensuring that the material roll and the rotating shaft 311 rotate synchronously.

[0046] Through the unwinding mechanism 3 described above, the unwound material (i.e. the adhesive) is output from the outlet 201 to the adhesive application mechanism 4, which then applies the adhesive to the surface of the workpiece.

[0047] In some embodiments, such as Figure 4-5 As shown, the adhesive applicator 44 includes a guiding assembly 41, a collecting assembly 42, a cutting assembly 43, and a pressing assembly 44. Both the guiding assembly 41 and the collecting assembly 42 are connected to the drive assembly 5. The guiding assembly 41 guides the adhesive released by the unwinding mechanism 3 along a preset trajectory; the collecting assembly 42 collects the used adhesive film; the cutting assembly 43 cuts the adhesive; and the pressing assembly 44 presses the adhesive against the surface of the workpiece.

[0048] The guide assembly 41 includes a first guide wheel 411, a second guide wheel 412, and a guide wheel assembly 413. Both the first guide wheel 411 and the second guide wheel 412 are rotatably mounted on the base frame 2. Along the direction of adhesive delivery, the guide wheel assembly 413 is located between the first guide wheel 411 and the second guide wheel 412, and is used to push the adhesive along a preset trajectory. The area on the base frame 2 for mounting the first guide wheel 411 and the second guide wheel 412 is provided with a support shaft fitted with a bearing, allowing the first guide wheel 411 and the second guide wheel 412 to be rotatably mounted on the base frame 2. It should be understood that the aforementioned delivery of the adhesive along a preset trajectory refers to the path initially wound around the adhesive mechanism 4 when the adhesive is wrapped around the adhesive applicator 1.

[0049] In some embodiments, the guide wheel assembly 413 includes a drive wheel 4131, a movable wheel 4132, and a drive member 4133. The drive wheel 4131 is connected to the drive assembly 5, and the movable wheel 4132 is rotatably mounted on the drive member 4133. The drive member 4133 is located on the base frame 2 and can drive the movable wheel 4132 to move closer to or away from the drive wheel 4131 to adjust the gap between the movable wheel 4132 and the drive wheel 4131 for the passage of the adhesive component. In this embodiment, the drive member 4133 is a cylinder. The telescopic end of the cylinder is provided with a support shaft for the rotation of the movable wheel 4132 and a bearing sleeved on the support shaft. The movable wheel 4132 is sleeved on the bearing to enable the movable wheel 4132 to rotate relative to the cylinder. It should be understood that the drive assembly 5 can drive the drive wheel 4131 to rotate. When the extension end of the cylinder extends, the gap between the drive wheel 4131 and the movable wheel 4132 is adjusted to just accommodate the passage of the adhesive component. The adhesive component is then conveyed forward by the rotation of the drive wheel 4131. When the extension end of the cylinder retracts, the gap between the drive wheel 4131 and the movable wheel 4132 is greater than the thickness of the adhesive component, allowing the adhesive component to pass smoothly between the drive wheel 4131 and the movable wheel 4132. At this time, the drive wheel 4131 and the movable wheel 4132 act as limiters, reducing the deviation of the adhesive component during the conveying process.

[0050] In some embodiments, such as Figure 4 As shown, the guide assembly 41 also includes a limiting wheel 414 and a mounting block 415. The mounting block 415 is mounted on the base frame 2, and the limiting wheel 414 is rotatably disposed on the mounting block 415. Along the direction of conveying the adhesive, the limiting wheel 414 is located between the second guide wheel 412 and the guide wheel assembly 413. Under the action of the limiting wheel 414, the adhesive can be further limited, reducing the deviation of the adhesive during the conveying process and affecting the normal operation of the adhesive application equipment 1.

[0051] Furthermore, such as Figure 5As shown, a guide seat 202 is provided on the base, and an arc-shaped groove 203 for guiding the adhesive is provided on the guide seat 202. The opening at one end of the arc-shaped groove 203 faces the limiting wheel 414, and the opening at the other end of the arc-shaped groove 203 faces the pressure wheel 444, so as to ensure that the adhesive can be conveyed toward the pressure wheel 444.

[0052] In some embodiments, the collecting component 42 includes a first rotating wheel 421, a second rotating wheel 422, and a take-up drum 423. Both the first rotating wheel 421 and the second rotating wheel 422 are rotatably mounted on the base frame 2. The take-up drum 423 is connected to the driving component 5. The film of the adhesive is wound onto the take-up drum 423 after passing through the first rotating wheel 421 and the second rotating wheel 422. Under the drive of the driving component 5, the take-up drum 423 rotates, thereby winding and collecting the film of the adhesive. Under the action of the first rotating wheel 421 and the second rotating wheel 422, the film of the adhesive can be wound along a pre-set path. In this embodiment, the take-up drum 423 includes a drum body 4231 and a pressure strip 4232 disposed on the drum body 4231. The drum body 4231 is connected to the driving component 5, and the pressure strip 4232 partially protrudes from the surface of the drum body 4231. Thus, under the action of the pressure strip 4232, it is beneficial to tighten the film wound on the cylinder 4231 and reduce the slippage of the film wound on the cylinder 4231 relative to the cylinder 4231.

[0053] In the above embodiments, any first guide wheel 411, second guide wheel 412, etc. that can rotate relative to the base frame 2 can be installed on the base frame 2 through a support shaft and a bearing sleeved on the support shaft. Of course, it can also be implemented in other ways, which will not be described in detail here.

[0054] In some embodiments, such as Figure 5 As shown, the cutting assembly 43 includes a telescopic member 431, a connecting block 432, a cutting member 433, and a support member 434. Both the telescopic member 431 and the support member 434 are mounted on the base frame 2. The connecting block 432 is connected to the telescopic end of the telescopic member 431. The cutting member 433 is mounted on the connecting block 432. The support member 434 is configured to support the adhesive member when the cutting member 433 presses against it. In this embodiment, the cutting member 433 has a built-in blade for cutting the adhesive member. The telescopic member 431 is a cylinder, and the telescopic end of the cylinder is connected to the connecting block 432. The connecting block 432 is connected to the cutting member 433. When the telescopic end of the cylinder extends, the connecting block 432 drives the cutting member 433 to move towards the support member 434, so that the cutting member 433 can cut the adhesive member. When the cylinder retracts, the adapter block 432 drives the cutting part 433 to move away from the carrier part 434, so as to form a channel between the carrier part 434 and the cutting part 433 for the bonding part to pass through.

[0055] The connection between the adapter block 432 and the cutting piece 433 can be achieved by one of them having a dovetail groove and the other having a structure that matches the shape of the dovetail groove. Of course, the adapter block 432 and the cutting piece 433 can also be connected in other ways, such as by direct screw connection, depending on the specific needs.

[0056] Furthermore, such as Figure 6 As shown, the carrier 434 includes a first carrier portion 4341 and a second carrier portion 4342 located on the same side. Both the first carrier portion 4341 and the second carrier portion 4342 are disposed towards the cutting member 433. Along the direction of the carrier 434 towards the cutting member 433, the first carrier portion 4341 is higher than the second carrier portion 4342. The second carrier portion 4342 is used to support the film of the adhesive. That is, when taking the side of the carrier 434 away from the cutting member 433 as the reference plane, along the direction of the carrier 434 towards the cutting member 433, the distance between the first carrier portion 4341 and the reference plane is greater than the distance between the second carrier portion 4342 and the reference plane. Thus, by utilizing the height difference between the first carrier portion 4341 and the second carrier portion 4342, when the cutting member 433 cuts the adhesive, it can be ensured that the cutting member 433 only cuts to the adhesive body without affecting the film, avoiding the cutting member 433 cutting the film and affecting the collection assembly 42's collection of the film. In this embodiment, the height difference between the first support portion 4341 and the second support portion 4342 is 0.05 mm.

[0057] In some embodiments, such as Figure 7As shown, the adhesive pressing assembly 44 includes a telescopic cylinder 441, a support block 442, a connector 443, and a pressure roller 444. The telescopic cylinder 441 is mounted on the base frame 2. The support block 442 is mounted on the telescopic end of the telescopic cylinder 441. The connector 443 is movably connected to the support block 442, and the pressure roller 444 is mounted on the connector 443. When the telescopic end of the telescopic cylinder 441 is in the first state, the connector 443 drives the pressure roller 444 to move relative to the support block 442 to press against the adhesive on the workpiece. When the telescopic end of the telescopic cylinder 441 is in the second state, the connector 443 and the pressure roller 444 move synchronously with the support block 442. It is understandable that the first and second states mentioned above are two opposite states. For example, the first state is when the telescopic end of the telescopic cylinder 441 is extended, and the second state is when the telescopic end of the telescopic cylinder 441 is retracted. Of course, the first state can also be when the telescopic end of the telescopic cylinder 441 is retracted, and the second state is when the telescopic end of the telescopic cylinder 441 is extended. Specifically, the first and second states can be determined according to the orientation of the telescopic end of the telescopic cylinder 441. In this embodiment, the telescopic end of the telescopic cylinder 441 is positioned away from the pressure roller 444. Therefore, when the telescopic end of the telescopic cylinder 441 is retracted, the connecting member 443 drives the pressure roller 444 to move relative to the support block 442 to press against the adhesive on the workpiece to be processed. When the telescopic end of the telescopic cylinder 441 is extended, the connecting member 443 and the pressure roller 444 move synchronously with the support block 442.

[0058] Understandably, the shape of the support block 442 can be customized to suit different needs; for example, it can be L-shaped or other shapes. The support block 442 is interconnected with the connector 443, and the connector 443 and the support block 442 can move relative to each other. This can be achieved by providing a slider on the support block 442, a guide rail (not shown) on the connector 443 that mates with the slider, and a limit block 4431 on the connector 443 to prevent the connector 443 from detaching from the support block 442 and falling off. When the pressure roller 444 on the connector 443 presses the bonded part against the surface of the workpiece, the pressure can be achieved by the weight of the connector 443 and the pressure roller 444 themselves.

[0059] When the telescopic cylinder 441 extends, the connecting member 443 and the pressure roller 444 move synchronously with the support block 442. When the telescopic cylinder 441 retracts, the pressure roller 444 presses against the adhesive on the surface of the workpiece, and the connecting member 443 moves relative to the support block 442 through the interaction between the slide rail and the slider. In this embodiment, the support block 442 includes a first support portion 4421 and a second support portion 4422 connected to the first support portion 4421. The first support portion 4421 is connected to the telescopic end of the telescopic cylinder 441, and the second support portion 4422 is used to connect to the connecting member 443.

[0060] Furthermore, the pressure bonding assembly 44 also includes a pressure sensor 445, a pressure plate 446, and an elastic element 447. The elastic element 447 is connected to the connector 443, and the pressure sensor 445 is connected to the support block 442. When the pressure roller 444 presses against the adhesive on the workpiece, the connector 443 presses against the elastic element 447, and the pressure plate 446 presses against the pressure sensor 445. When the pressure roller 444 presses against the adhesive on the surface of the workpiece, the connector 443 moves relative to the support block 442 and squeezes the elastic element 447, so that the pressure plate 446 presses against the pressure sensor 445. The reaction force of the elastic element 447 acts on the connector 443, allowing the pressure roller 444 to press the adhesive against the surface of the workpiece. Thus, the pressure sensor 445 can detect the pressure applied by the pressure roller 444 to the workpiece, so as to adjust the distance between the pressure roller 444 and the workpiece as needed. In this embodiment, the support block 442 further includes a third support portion 4423, which is connected to the second support portion 4422. The third support portion 4423 is used to install the pressure sensor 445.

[0061] The elastic element 447 can be a spring, a spring bar with a built-in spring, or any other type, as long as it can be compressed and exert a reaction force on the connector 443. In this embodiment, the elastic element 447 is a spring bar, and the connector 443 is provided with a step for engaging with the boss of the spring bar. When the telescopic end of the telescopic cylinder 441 retracts, the connector 443 moves relative to the support block 442. Under the action of the step, the spring built into the spring bar is compressed by the movement of the connector 443. The spring built into the spring bar pushes the connector 443 in the opposite direction to restore its deformation, so that the pressure roller 444 on the connector 443 can press against the adhesive.

[0062] In some embodiments, a guide structure (not shown) is provided between the telescopic cylinder 441 and the support block 442 to reduce the risk of the support block 442 shifting during the telescopic extension and retraction of the telescopic cylinder 441. Understandably, the guide structure can be a combination of a guide block and a guide groove, or other structures; there is no specific limitation.

[0063] In some embodiments, please combine Figure 1 and Figure 8The drive assembly 5 includes a drive motor 51, a first synchronous pulley 52, a second synchronous pulley 53, and a synchronous belt 54. The drive motor 51 is mounted on the base frame 2. The first synchronous pulley 52 is connected to the guide wheel group 413 of the guide assembly 41, and the second synchronous pulley 53 is connected to the collecting assembly 42. The synchronous belt 54 is sleeved on the first synchronous pulley 52 and the second synchronous pulley 53. The output end of the drive motor 51 is connected to the first synchronous pulley 52. ​​In this embodiment, the first synchronous pulley 52 is coaxially connected to the drive pulley 4131, and the second synchronous pulley 53 is coaxially connected to the take-up drum 423. Thus, when the drive motor 51 drives the first synchronous pulley 52 to rotate, the second synchronous pulley 53 rotates under the action of the synchronous belt 54 to realize the rotation of the take-up drum 423. This is beneficial for the adhesive to be fed under the push of the drive pulley 4131 while the remaining film after use can be wound up.

[0064] In some embodiments, the drive assembly 5 further includes a damping element 55, which is connected to the first synchronous pulley 52 or the second synchronous pulley 53. The damping element 55 provides a damping effect to the first synchronous pulley 52 or the second synchronous pulley 53, reducing the risk of inertial idling during operation and helping to ensure the stability of the bonding material feeding. In this embodiment, the damping element 55 is a magnetic damper 35, which is connected to the second synchronous pulley 53.

[0065] In some embodiments, the drive assembly 5 further includes a tensioning pulley and a mounting shaft for mounting the tensioning pulley. The mounting shaft is mounted on the base frame 2, and the tensioning pulley is mounted on the other end of the mounting shaft. The tensioning pulley can rotate on the mounting shaft and presses against the timing belt, thereby tightening the timing belt and reducing the risk of timing belt slippage.

[0066] In use, the adhesive roll is installed onto the unwinding mechanism 3, which then releases the adhesive to supply the adhesive application structure. The adhesive supplied from the unwinding mechanism 3 must first undergo initial winding, i.e., the adhesive is pre-wound onto the adhesive application mechanism 4. Specifically, as follows... Figure 9 As shown, after the adhesive is wound by the first guide wheel 411, the guide wheel group 413 and the second guide wheel 412, it extends out from the guide seat 202 of the base frame 2 and is placed at the lower end of the pressure roller 444. Along the winding path of the adhesive, the portion of the adhesive that exceeds the guide seat 202 needs to separate the film from the adhesive body. The separated film is wound onto the take-up drum 423 after passing through the first rotating wheel 421 and the second rotating wheel 422.

[0067] After the initial winding of the adhesive is completed, the control module controls the telescopic cylinder 441 to work and be in the first state. The connector 443 drives the pressure roller 444 to move relative to the support block 442, so that the pressure roller 444 presses the adhesive body of the adhesive onto the surface of the workpiece. Then, while the adhesive applicator 1 moves relative to the workpiece, the drive component 5 also works, thereby continuously bonding the adhesive body of the adhesive to the surface of the workpiece. When the adhesive applicator 1 moves to the preset finishing position, the drive component 5 stops working first, and the cutting component 43 starts working. The telescopic component 431 drives the adapter block 432 to move the cutting component 433 closer to the support component 434, thereby cutting the adhesive body of the adhesive. After the adhesive body of the adhesive is broken, the telescopic component 431 drives the adapter block 432 to move the cutting component 433 back. Then, the adhesive applicator 1 moves a preset distance relative to the workpiece to press the adhesive body on the surface of the workpiece. Then, the control module controls the telescopic cylinder 441 to be in the second state, and the pressure roller 444 moves away from the surface of the workpiece. The driving component 4133 drives the movable wheel 4132 closer to the drive wheel 4131 to press against the adhesive component. The driving assembly 5 drives the drive wheel 4131 to rotate, so that the adhesive component continues to be conveyed forward for a preset length until there is an adhesive body to be pressed under the pressure roller 444. Then the driving assembly 5 stops working, and the driving component 4133 drives the movable wheel 4132 away from the drive wheel 4131 to release the adhesive component. After the adhesive application device 1 moves relative to the workpiece to another bonding position, the above process is repeated to complete the processing of the other bonding position.

[0068] The adhesive application device 1 provided in this application includes a base frame 2, a drive assembly 5, an unwinding mechanism 3, and an adhesive application mechanism 4. The drive assembly 5 is mounted on the base frame 2 and is used to drive the guide assembly 41 to guide and transport the adhesive, and to drive the collection assembly 42 to collect the film of the used adhesive. The unwinding mechanism 3 is located on the base frame 2 and is used to release the adhesive. The adhesive application mechanism 4 is located on the base frame 2 and includes a guide assembly 41, a pressing assembly 44, a collection assembly 42, and a cutting assembly 43. The guide assembly 41 and the collection assembly 42 are both connected to the drive assembly 5. The guide assembly 41 is used to guide the adhesive released by the unwinding mechanism 3 along a preset trajectory under the drive of the drive assembly 5. The pressing assembly 44 is used to press the adhesive against the surface of the workpiece to be processed. The collection assembly 42 is used to collect the film of the used adhesive under the drive of the drive assembly 5. The cutting assembly 43 is used to cut the adhesive. The adhesive application device 1 described above can automatically apply adhesive to the surface of the workpiece to be processed, which is beneficial to improving the bonding efficiency.
