Description

Technical Field

[0001] This invention relates to the field of processing and manufacturing technology, and specifically to an automatic adhesive removal device and method for FDS. Background Technology

[0002] FDS (Flow Drill Screw) is a cold forming process that uses high-speed rotation to heat-deform sheet metal before tapping and riveting. It is typically used in conjunction with structural adhesive. First, the lower-level parts are fixed in a fixture, adhesive is applied, and then the upper-level parts are clamped onto the fixture. After the fixture is locked, FDS is performed.

[0003] Under non-constant temperature conditions or when applying adhesive manually, the amount of adhesive applied cannot be accurately controlled. Even when using robotic adhesive application, a slight overflow is generally required to ensure joint strength. After the clamps are tightened, structural adhesive may seep into the pre-riveting position. At this point, the FDS equipment applies pressure again, increasing the amount of overflow. During FDS, the gun head rotates at high speed, causing structural adhesive to adhere to the gun head, tool holder, grippers, and pressure plate. When too much structural adhesive adheres to these devices, the rivets cannot lock tightly with the gun head, and the grippers cannot fully open. Consequently, during FDS operation, the rivets cannot be perpendicular to the plane of the upper plate being riveted, resulting in a misalignment of the riveting position. If the upper plate has pre-drilled holes (if the upper plate is made of high-strength steel), the rivets may shift out of the pre-drilled holes and be directly riveted to the high-strength steel plate, leading to failure to rivet, thus affecting the quality of FDS and significantly reducing the lifespan of the equipment.

[0004] Currently, most adhesive removal is done manually by wiping the FDS equipment, which is inefficient and affects processing efficiency. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this invention is to provide an automatic FDS adhesive removal device and method to solve the problem of low adhesive removal efficiency and reduced processing efficiency in existing FDS wiping equipment.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: On the one hand, this application provides an automatic adhesive removal device for FDS, comprising: A cover is provided to cover the gripper, and the bottom of the cover is provided with a through hole for the blade assembly to extend out. Two adhesive removal components are disposed in and connected to the aforementioned housing, respectively located on both sides of the blade bar. The adhesive removal components include a first magnetic adhesive removal element, and the two aforementioned first magnetic adhesive removal elements are used to clamp the blade bar on both sides when removing adhesive from the outer wall of the blade bar.

[0007] In some optional embodiments, each of the above-mentioned adhesive removal components further includes two second magnetic adhesive removal elements, which are used to clamp the grippers on both sides when removing adhesive from the grippers.

[0008] In some optional embodiments, the adhesive removal assembly further includes an annular member connected to the inner wall of the cover, the annular member being sleeved on the outside of the gripper, two of the second magnetic adhesive removal components being connected inside the annular member by a second spring and located on opposite sides of the gripper respectively; the first magnetic adhesive removal component being connected to the side of the annular member near the blade bar by a first spring.

[0009] In some alternative embodiments, the adhesive removal assembly is slidably connected to the housing via a sliding rod and can move along the length of the gripper.

[0010] In some optional embodiments, a blade adhesive removal assembly is also included, which is used to rub against the surface of the blade when the blade retracts to a predetermined position within the housing. The blade adhesive removal assembly includes: A cleaning component, used for rubbing the surface of the aforementioned cutter head; A connecting rod, one end of which is connected to the aforementioned cleaning component; A driving component, which is connected to the other end of the connecting rod, drives the connecting rod to rotate, thereby moving the cleaning component to the blade head.

[0011] On the other hand, this application also provides an automatic FDS adhesive removal method, implemented using the aforementioned automatic FDS adhesive removal device, comprising the following steps: Detect the amount of adhesive on the FDS equipment; When there is too much adhesive on the FDS equipment, the two first magnetic adhesive removal components are energized, so that the two first magnetic adhesive removal components are clamped on both sides of the cutter bar. When the aforementioned cutter bar moves relative to the aforementioned first magnetic adhesive removal component, adhesive is removed from the outer wall of the aforementioned cutter bar.

[0012] In some optional embodiments, it also includes: When there is too much adhesive on the FDS device, the second magnetic adhesive removal component is energized, so that the two second magnetic adhesive removal components are clamped on both sides of the gripper. When the second magnetic adhesive remover and the first magnetic adhesive remover move relative to the gripper, the adhesive is removed from the gripper.

[0013] In some optional embodiments, it also includes: When there is too much adhesive on the FDS device, the connecting rod rotates, causing the cleaning component to move to the blade head and rub against the blade head surface.

[0014] In some optional embodiments, the above-mentioned detection of adhesive amount on the FDS device includes: The riveting time of the FDS device is detected when the riveting time t ≥ When the amount of adhesive on the FDS equipment is too high, it is determined that there is too much adhesive, where t is the riveting time. The theoretical riveting time is given by s, where s is the safety factor.

[0015] In some optional embodiments, detecting the amount of adhesive on the FDS device further includes identifying the amount of excess adhesive on the board through visual sensing, and determining that there is too much adhesive on the FDS device when there is too much adhesive on the board.

[0016] Compared with the prior art, the advantages of the present invention are as follows: by setting the adhesive removal component inside the housing, and using the first magnetic adhesive removal component to clamp the two sides of the cutter bar to remove the adhesive, for example by the relative movement of the cutter bar and the first magnetic adhesive removal component to make the first magnetic adhesive removal component rub against the surface of the cutter bar, thereby removing the adhesive on the surface of the cutter bar, so as to ensure the quality of FDS and extend the service life of the equipment, while not interfering with FDS operation.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Before FDS operation, the lower layer panel is first fixed in the fixture, glue is applied, and then the upper layer panel is clamped onto the fixture. After the fixture is locked, FDS is performed. Therefore, after the fixture is clamped, some structural adhesive will seep into the pre-riveted position. When the cover 2 presses the panel down, the amount of adhesive overflow will increase. As a result, during FDS operation, the structural adhesive will stick to the cutter head, cutter bar, grippers, and cover.

[0023] Therefore, on the one hand, such as Figure 1 and Figure 3 As shown, this application provides an FDS automatic adhesive removal device, including a housing 2 and an adhesive removal component 1 disposed within the housing 2. Adhesive is removed from the surface of the blade 41 by the relative movement of the adhesive removal component 1 relative to the blade 41 within the housing 2.

[0024] Specifically, the cover 2 is used to cover the gripper 3, and the bottom of the cover 2 is provided with a through hole for the blade assembly 4 to extend out; two adhesive removal assemblies 1, which are provided inside the cover 2 and connected to it, are respectively located on both sides of the blade shank 41. The adhesive removal assembly 1 includes a first magnetic adhesive removal component 11, and the two first magnetic adhesive removal components 11 are used to clamp the blade shank 41 on both sides when removing adhesive from the outer wall of the blade shank 41.

[0025] Understandable, such as Figure 2As shown, the cutter head assembly 4 includes a cutter bar 41 and a cutter head 42 connected to the lower end of the cutter bar 41. The cutter bar 41 can drive the cutter head 42 to move up and down inside the cover 2 and extend out of the cover 2 through the through hole at the bottom of the cover 2. The two grippers 3 can open or close on both sides of the cutter bar 41. In the initial position, this is state a in the diagram, with the two grippers 3 close to both sides of the cutter bar 41 in a closed state. During the FDS operation, the cover 2 and the cutter head assembly 4 move together downwards towards the plate until the bottom of the cover 2 abuts against the plate, and the through hole aligns with the riveting point, which is state b in the diagram. Then, the grippers 3 open to both sides, which is state c in the diagram. The cutter bar 41 moves downwards until the cutter head 42 extends out of the cover 2 from the through hole and rotates, causing the cutter head 42 to rotate the rivet to rivet the plate, which is state d in the diagram. After riveting, the cutter bar 41 drives the cutter head 42 to retract into the cover 2, which is state e in the diagram. The two grippers 3 close towards the cutter bar 41, which is state f in the diagram. Finally, the entire device moves upwards and no longer presses against the plate, returning to the initial state g.

[0026] Therefore, when removing adhesive from the cutter bar 41, it should be done when the cutter bar 41 has completed the FDS operation and retracted into the cover 2, and the two grippers 3 are in the open state, that is, when removing adhesive in state e, so as to avoid interfering with the FDS operation.

[0027] Optionally, when the gripper 3 opens and the cutter bar 41 begins to retract within the cover 2, the two first magnetic adhesive removal components 11 are clamped and adsorbed onto the cutter bar 41. Since the first magnetic adhesive removal components 11 are connected inside the cover 2, and the cutter bar 41 moves within the cover 2, the cutter bar 41 has a relative displacement with respect to the first magnetic adhesive removal components 11, thereby allowing the first magnetic adhesive removal components 11 to rub against the surface of the cutter bar 41 and remove the adhesive from the cutter bar 41.

[0028] In this example, to control the first magnetic adhesive removal component 11 to adhere to the blade 41 and remove adhesive from it when the blade 41 begins to retract within the housing 2, the first magnetic adhesive removal component 11 is configured to include a first electromagnetic plate 112 and a first felt plate 113, with the first felt plate 113 located on the side closest to the blade 41. When the blade 41 begins to retract within the housing 2, the two first electromagnetic plates 112 are energized, causing them to attract each other and clamp onto both sides of the blade 41. At this time, as the blade 41 retracts within the housing 2, the first felt plate 113 rubs against the surface of the blade 41, removing the adhesive from it.

[0029] In some optional embodiments, each of the above-mentioned adhesive removal components 1 further includes two second magnetic adhesive removal elements 12, which are used to clamp the gripper 3 on both sides when removing adhesive from the gripper 3.

[0030] Since the function of the gripper 3 is to hold the screw located at the cutter head 42 to complete the riveting, it may also have adhesive residue. In this example, the adhesive removal assembly 1 also includes two second magnetic adhesive removal components 12 to remove adhesive from the gripper 3. When the two second magnetic adhesive removal components 12 are held and attracted to the gripper 3 and move relative to the gripper 3, the adhesive residue on the gripper 3 is removed by rubbing against the surface of the gripper 3.

[0031] In this example, the second magnetic adhesive removal component 12 includes a second electromagnetic plate 123 and a second felt plate 122, with the second felt plate 122 located on the side closest to the gripper 3. When the gripper 3 begins to close, the second electromagnetic plate 123 is energized, causing the two second felt plates 122 to be held and attracted to both sides of the gripper 3 by the second electromagnetic plate 123. Optionally, during the closing process of the gripper 3, the relative position of the second magnetic adhesive removal component 12 with respect to the cover 2 remains unchanged, and the second magnetic adhesive removal component 12 rubs against the surface of the gripper 3 to remove the adhesive.

[0032] In some alternative embodiments, such as Figure 3 As shown, the adhesive removal assembly 1 further includes an annular component 13 connected to the inner wall of the cover 2. The annular component 13 is used to be sleeved on the outside of the gripper 3. The two second magnetic adhesive removal components 12 are connected inside the annular component 13 by the second spring 121 and are located on opposite sides of the gripper 3 respectively. The first magnetic adhesive removal component 11 is connected to the side of the annular component 13 near the blade 41 by the first spring 111.

[0033] It is understandable that when it is necessary to remove adhesive from the tool holder 41, the first magnetic adhesive removal component 11 is energized, causing the two first magnetic adhesive removal components 11 to clamp and adhere to both sides of the tool holder 41, at which time the first spring 111 is stretched; after the adhesive removal is completed, the first magnetic adhesive removal component 11 is no longer energized, the two first magnetic adhesive removal components 11 no longer attract each other, the first spring 111 returns to its initial state, and the two first magnetic adhesive removal components 11 no longer clamp the tool holder 41. Similarly, when it is necessary to remove adhesive from the gripper 3, the second magnetic adhesive removal component 12 is energized, causing the two second magnetic adhesive removal components 12 to clamp and adhere to both sides of the gripper 3, at which time the second spring 121 is stretched; after the adhesive removal is completed, the second magnetic adhesive removal component 12 is no longer energized, the two second magnetic adhesive removal components 12 no longer attract each other, the second spring 121 returns to its initial state, and the two second magnetic adhesive removal components 12 no longer clamp the gripper 3.

[0034] Optionally, the first magnetic adhesive removal component 11 and the second magnetic adhesive removal component 12 can be magnetic components. When adhesive needs to be removed from the tool bar 41, the tool bar 41 can be energized to make it magnetic, causing the two first magnetic adhesive removal components 11 to be attracted to the tool bar 41. When adhesive needs to be removed from the gripper 3, the gripper 3 can be energized to make it magnetic, causing the two second magnetic adhesive removal components 12 to be attracted to the gripper 3. However, in the embodiments of this application, the gripper and the tool bar should be made of electromagnetic materials, such as an iron core with an externally wound conductive winding matching its power.

[0035] Preferably, the first felt sheet 113 can be configured to adapt to the outer wall shape of the blade 41, and the second felt sheet 122 can be configured to adapt to the outer wall shape of the gripper 3, so as to improve the adhesive removal effect.

[0036] In other embodiments, a connector with a certain elastic deformation capability can be used to connect the first magnetic adhesive removal component 11 and the second magnetic adhesive removal component 12 to the ring component 13, so as to ensure that they can approach each other when adhesive removal is required and move away from each other after adhesive removal is completed, so as not to affect the FDS operation.

[0037] In some optional embodiments, the adhesive removal component 1 is slidably connected to the cover 2 via the sliding rod 6 and can move along the length direction of the gripper 3.

[0038] In the above embodiment, the adhesive removal of the gripper 3 is achieved by the relative displacement between the gripper 3 and the second magnetic adhesive removal component 12 caused by the opening and closing of the gripper 3 within the cover 2. However, the adhesive removal range is small and the removal effect is poor. Therefore, in order to better remove adhesive from the gripper 3, in this embodiment, the adhesive removal assembly 1 is slidably connected to the cover 2 via the sliding rod 6. When adhesive removal of the gripper 3 is required, the two second magnetic adhesive removal components 12 are attracted and clamped on both sides of the gripper 3. At this time, the sliding rod 6 drives the entire adhesive removal assembly 1 to move along the length direction of the gripper 3, so that the two second magnetic adhesive removal components 12 move and rub on the gripper 3 to remove adhesive.

[0039] Optionally, the inner wall of the cover 2 is provided with a slide rail along the length of the gripper 3, and the sliding rod 6 is driven by a drive component to move along the slide rail.

[0040] In some optional embodiments, the above-mentioned FDS automatic adhesive removal device further includes a blade adhesive removal assembly 5, which is used to rub the surface of the blade 42 when the blade 42 retracts to a set position inside the cover 2.

[0041] Specifically, the aforementioned blade head adhesive removal assembly 5 includes a cleaning component 51, a connecting rod 52, and a driving component. The cleaning component 51 is used to rub against the surface of the aforementioned blade head 42. One end of the connecting rod 52 is connected to the cleaning component 51. The driving component is connected to the other end of the connecting rod 52 to drive the connecting rod 52 to rotate, thereby moving the cleaning component 51 to the aforementioned blade head 42.

[0042] In this example, the cleaning element 51 is a rotatable felt head. When the cleaning element 51 moves to the cutter head 42, the cleaning element 51 rotates relative to the cutter head 42 to remove the adhesive from the cutter head 42.

[0043] It should be noted that the adhesive removal assembly 5 is not limited to being installed inside the housing 2. It only needs to move the cleaning component 51 to the location of the cutter head 42 when the cutter head 42 retracts to the set position inside the housing, thus generating friction with the cutter head 42. Of course, in this example, the adhesive removal assembly 5 moves to below the cutter head 42 to remove adhesive. Therefore, after adhesive removal is complete, or when it is no longer necessary, the adhesive removal assembly 5 should be moved away from the cutter head assembly 4 to avoid affecting the FDS operation.

[0044] On the other hand, this application also provides an automatic FDS adhesive removal method, implemented using the aforementioned automatic FDS adhesive removal device, comprising the following steps: S1: Detect the amount of adhesive on the FDS device.

[0045] In some optional embodiments, when the board has pre-drilled holes for riveting, excess adhesive will spread across the pre-drilled hole locations. Therefore, the amount of excess adhesive on the board can be identified using a visual sensing device. When there is excessive excess adhesive on the board, it is determined that there is too much adhesive on the FDS device.

[0046] In some optional embodiments, when there are no pre-drilled holes on the board, the vision sensing device cannot identify the amount of adhesive overflow on the board. In this case, the riveting time of the FDS device is detected, and when the riveting time t≥ When the amount of adhesive on the FDS equipment is too high, it is determined that there is too much adhesive, where t is the riveting time. The theoretical riveting time is given by s, where s is the safety factor.

[0047] Preferably, the value of s is in the range of 1.1 to 1.5. When the plates are connected by aluminum-aluminum joints, the lower limit of 1.1 is taken, and when the plates are connected by steel joints, the upper limit of 1.5 is taken.

[0048] In other embodiments, the adhesive can be removed from the grippers and the tool holder when they move within the housing and the grippers open and close within the housing, without relying on the riveting time. This can be done after each FDS operation and before the start of the next FDS operation.

[0049] S2: When there is too much adhesive on the FDS device, the two first magnetic adhesive removal components 11 are energized, so that the two first magnetic adhesive removal components 11 are clamped on both sides of the cutter bar 41.

[0050] In this example, to control the first magnetic adhesive removal component 11 to adhere to the blade 41 and remove adhesive from it when the blade 41 begins to retract within the housing 2, the first magnetic adhesive removal component 11 is configured to include a first electromagnetic plate 112 and a first felt plate 113, with the first felt plate 113 located on the side closest to the blade 41. When the blade 41 begins to retract within the housing 2, the two first electromagnetic plates 112 are energized, causing them to attract each other and clamp onto both sides of the blade 41.

[0051] S3: When the above-mentioned cutter bar 41 moves relative to the above-mentioned first magnetic adhesive removal component 11, the adhesive is removed from the outer wall of the above-mentioned cutter bar 41.

[0052] When the cutter bar 41 retracts inside the cover 2, the first felt sheet 113 rubs against the surface of the cutter bar 41 to remove the adhesive on the cutter bar 41.

[0053] In some optional embodiments, the above-described adhesive removal method further includes: S4: When there is too much adhesive on the FDS device, the second magnetic adhesive removal component 12 is energized, so that the two second magnetic adhesive removal components 12 are clamped on both sides of the gripper 3.

[0054] Since the function of the gripper 3 is to hold the screw located at the cutter head 42 to complete the riveting, it may also be covered with adhesive. In this example, the adhesive removal component 1 in the above-mentioned adhesive removal device also includes two second magnetic adhesive removal components 12 to remove adhesive from the gripper 3.

[0055] Specifically, the second magnetic adhesive removal component 12 includes a second electromagnetic plate 123 and a second felt plate 122, with the second felt plate 122 located on the side closest to the gripper 3. When the gripper 3 begins to close, the second electromagnetic plate 123 is energized, causing the two second felt plates 122 to be held and attracted to both sides of the gripper 3 by the second electromagnetic plate 123.

[0056] S5: When the second magnetic adhesive remover 12 and the first magnetic adhesive remover 11 move relative to the gripper 3, the adhesive is removed from the gripper 3.

[0057] During the closing process of the gripper 3, the relative position of the second magnetic adhesive removal component 12 with respect to the cover 2 remains unchanged. The second magnetic adhesive removal component 12 is rubbed against the surface of the gripper 3 by the closing of the gripper 3 to remove the adhesive.

[0058] In some optional embodiments, the adhesive removal assembly 1 further includes an annular member 13 connected to the inner wall of the cover 2. The annular member 13 is used to be sleeved on the outside of the gripper 3. The two second magnetic adhesive removal components 12 are connected inside the annular member 13 by a second spring 121 and are located on opposite sides of the gripper 3 respectively. The first magnetic adhesive removal component 11 is connected to the side of the annular member 13 near the blade shank 41 by a first spring 111.

[0059] It is understandable that when it is necessary to remove adhesive from the tool holder 41, the first magnetic adhesive removal component 11 is energized, causing the two first magnetic adhesive removal components 11 to clamp and adhere to both sides of the tool holder 41, at which time the first spring 111 is stretched; after the adhesive removal is completed, the first magnetic adhesive removal component 11 is no longer energized, the two first magnetic adhesive removal components 11 no longer attract each other, the first spring 111 returns to its initial state, and the two first magnetic adhesive removal components 11 no longer clamp the tool holder 41. Similarly, when it is necessary to remove adhesive from the gripper 3, the second magnetic adhesive removal component 12 is energized, causing the two second magnetic adhesive removal components 12 to clamp and adhere to both sides of the gripper 3, at which time the second spring 121 is stretched; after the adhesive removal is completed, the second magnetic adhesive removal component 12 is no longer energized, the two second magnetic adhesive removal components 12 no longer attract each other, the second spring 121 returns to its initial state, and the two second magnetic adhesive removal components 12 no longer clamp the gripper 3.

[0060] In some optional embodiments, the adhesive removal component 1 is slidably connected to the cover 2 via the sliding rod 6 and can move along the length direction of the gripper 3.

[0061] In the above embodiment, the adhesive removal of the gripper 3 is achieved by the relative displacement between the gripper 3 and the second magnetic adhesive removal component 12 caused by the opening and closing of the gripper 3 within the cover 2. However, the adhesive removal range is small and the removal effect is poor. Therefore, in order to better remove adhesive from the gripper 3, in this embodiment, the adhesive removal assembly 1 is slidably connected to the cover 2 via the sliding rod 6. When adhesive removal of the gripper 3 is required, the two second magnetic adhesive removal components 12 are attracted and clamped on both sides of the gripper 3. At this time, the sliding rod 6 drives the entire adhesive removal assembly 1 to move along the length direction of the gripper 3, so that the two second magnetic adhesive removal components 12 move and rub on the gripper 3 to remove adhesive.

[0062] In some optional embodiments, the above-described adhesive removal method further includes: S6: When there is too much adhesive on the FDS device, the connecting rod 52 rotates to move the cleaning component 51 to the blade head 42 and rubs against the surface of the blade head 42.

[0063] It is understood that the aforementioned FDS automatic adhesive removal device also includes a blade adhesive removal assembly 5, which is used to rub the surface of the blade 42 when the blade 42 retracts to a set position inside the cover 2.

[0064] Specifically, the aforementioned blade head adhesive removal assembly 5 includes a cleaning component 51, a connecting rod 52, and a driving component. The cleaning component 51 is used to rub against the surface of the aforementioned blade head 42. One end of the connecting rod 52 is connected to the cleaning component 51. The driving component is connected to the other end of the connecting rod 52 to drive the connecting rod 52 to rotate, thereby moving the cleaning component 51 to the aforementioned blade head 42.

[0065] In this example, the cleaning element 51 is a rotatable felt head. When the cleaning element 51 moves to the cutter head 42, the cleaning element 51 rotates relative to the cutter head 42 to remove the adhesive from the cutter head 42.

[0066] It should be noted that the adhesive removal assembly 5 is not limited to being installed inside the housing 2. It only needs to move the cleaning component 51 to the location of the cutter head 42 when the cutter head 42 retracts to the set position inside the housing, thus generating friction with the cutter head 42. Of course, in this example, the adhesive removal assembly 5 moves to below the cutter head 42 to remove adhesive. Therefore, after adhesive removal is complete, or when it is no longer necessary, the adhesive removal assembly 5 should be moved away from the cutter head assembly 4 to avoid affecting the FDS operation.

[0067] Of course, step S6 can be performed simultaneously with step S3. That is, when cleaning the gripper 3, the cutter head 42 can be cleaned and degummed at the same time. This can shorten the degumming time of the FDS device and improve the degumming efficiency.

[0068] After a certain number of adhesive removal cycles, the felt sheet should be replaced promptly to ensure the adhesive removal effect.

[0069] This invention discloses an automatic adhesive removal device and method for FDS (Flush Mounted Dish). An adhesive removal assembly is installed within a housing. A first magnetic adhesive removal element clamps both sides of a cutter bar. The relative movement of the cutter bar and the first magnetic adhesive removal element causes the element to rub against the cutter bar surface, thereby removing adhesive from the gripper surface. The first magnetic adhesive removal element comprises a first electromagnetic plate and a first felt plate. The timing and duration of adhesive removal by the felt plate on the cutter bar are controlled by energizing and de-energizing the device, thus avoiding interference with FDS operations. Two second magnetic adhesive removal elements are used on the grippers to remove adhesive, preventing interference with gripper opening and closing. The adhesive removal assembly is slidably connected within the housing via a sliding rod, allowing for better adhesive removal from the grippers and a wider removal range. Furthermore, the inclusion of a cutter head adhesive removal assembly also removes adhesive from the cutter head, improving riveting accuracy and reducing defect rates.
