Description

Technical Field

[0001] The present invention relates to the technical field of 3C product assembly, and in particular to a method for applying a protective film. Background Art

[0002] The Type-C data cable includes a Type-C connector and a housing mounted outside the connector. Existing Type-C data cable production equipment typically clamps the housing and Type-C connector during the production process before installing them. To prevent scratches on the Type-C connector during the clamping process, a protective film is applied to the clamping area of ​​the Type-C connector. Existing protective films are typically secured to the Type-C connector simply by wrapping them around it. The wrapping process requires clamping and flipping the Type-C connector, which can also scratch the outer surface of the Type-C connector. Furthermore, the protective film cannot be attached to the clamping area, limiting the area available for attachment. This can cause subsequent processing to scratch the unprotected portion of the Type-C connector, potentially rendering the Type-C connector useless.

[0003] For this reason, continue to study a kind of applying method of protective film, to solve the above-mentioned problem. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0054] like Figures 1 to 6 As shown, this embodiment provides a method for applying a protective film, which is applied to a film applying device. The film applying device includes a frame 100, a third movable assembly 230, an adsorption head 300, and a toggle assembly 400. The frame 100 has a first assembly position 122; the third movable assembly 230 is disposed on the frame 100; the adsorption head 300 is disposed at the output end of the third movable assembly 230. The adsorption head 300 has a groove 310, and the toggle end of the toggle assembly 400 can move left or right. The toggle end of the toggle assembly 400 moves left or right in the X direction.

[0055] The method for applying the protective film includes the following steps:

[0056] The workpiece 1000 is transferred to the first assembly station 122 .

[0057] A sheet-like protective film 2000 is pasted to the upper side wall of the workpiece 1000. The protective film 2000 is divided into a left part, a middle part and a right part. The middle part is located directly above the workpiece 1000, the left part is located on the upper left of the workpiece 1000, and the right part is located on the upper right of the workpiece 1000.

[0058] The adsorption head 300 is driven by the third moving component 230 to flow between the first assembly position 122 and the wrapping position. The adsorption hole 320 of the adsorption head 300 transfers the workpiece 1000 and the protective film 2000 to the wrapping position. The adsorption head 300 can move in the vertical direction. In the process of the groove 310 approaching the workpiece 1000 downward, the groove wall of the groove 310 bends the left and right parts of the protective film 2000 downward to form a left side part 2100 and a right side part 2200 respectively. The part of the left side part 2100 close to the middle of the protective film 2000 is attached to the left side wall of the workpiece 1000, and the part of the right side part 2200 close to the middle of the protective film 2000 is attached to the right side wall of the workpiece 1000.

[0059] The toggle end of the toggle assembly 400 is driven to move leftward to bend the lower portion of the right side portion 2200 and attach it to the lower side wall 1100 of the workpiece 1000 ; the toggle end of the toggle assembly 400 is driven to move rightward to bend the lower portion of the left side portion 2100 and attach it to the lower side wall 1100 of the workpiece 1000 .

[0060] The method for applying the protective film is to use a sheet-like protective film 2000, first stick the protective film 2000 on the upper side wall of the workpiece 1000, and then adsorb the workpiece 1000 through the adsorption head 300 provided with a groove 310. During the downward adsorption process, the groove wall of the groove 310 bends the left and right parts of the protective film 2000 downward to form a left side part 2100 and a right side part 2200 respectively. The part of the left side part 2100 close to the middle is stuck to the left side wall of the workpiece 1000, and the part of the right side part 2200 close to the middle is stuck to the right side wall of the workpiece 1000; in the wrapping position, the toggle end of the toggle component 400 moves to the left to stick the right side part 2200 to the lower side of the workpiece 1000 Wall 1100, the toggle end of the toggle assembly 400 moves to the right to stick the left side portion 2100 to the lower side wall 1100 of the workpiece 1000. At this point, the wrapping of the four sides of the workpiece 1000 has been completed, and due to the wrapping process, there is no need to turn the workpiece 1000 over, and when the workpiece 1000 is transferred, the middle part of the protective film 2000 is adsorbed, and the position of the workpiece 1000 where the protective film 2000 is not attached will not be clamped, thereby avoiding scratches on the outer surface of the workpiece 1000, and the protective film 2000 can more comprehensively wrap the outer surface of the workpiece 1000, so that the workpiece 1000 can be more comprehensively protected, thereby improving the safety of subsequent processing.

[0061] It should be noted that the protective film 2000 is bonded to the workpiece 1000 . Therefore, by adsorbing the middle portion of the protective film 2000 , the workpiece 1000 can be transferred simultaneously with the transfer of the protective film 2000 .

[0062] Regarding the structure of the shifting assembly 400, in some embodiments, a shifting claw structure may be provided. Specifically, in a first embodiment of this embodiment, the shifting assembly 400 includes a right shifting claw 421. As the right shifting claw 421 moves leftward, the right side portion 2200 abuts against the lower sidewall 1100 of the workpiece 1000. As the right shifting claw 421 moves rightward, the left side portion 2100 abuts against the lower sidewall 1100 of the workpiece 1000. It should be noted that before shifting the left side portion 2100 or the right side portion 2200, the position of the right shifting claw 421 relative to the left side portion 2100 and the position of the right shifting claw 421 relative to the right side portion 2200 must be adjusted. Specifically, when shifting the right side portion 2200, the right shifting claw 421 must be adjusted to the right of the right side portion 2200; when shifting the left side portion 2100, the right shifting claw 421 must be adjusted to the left of the left side portion 2100.

[0063] In the second embodiment of the present invention, the shifting assembly 400 includes a left shifting claw 411, which moves rightward to abut the left side portion 2100 against the lower side wall 1100 of the workpiece 1000. Similarly, the left shifting claw 411 can also complete the abutment of the right side portion 2200.

[0064] In a third embodiment of the present invention, the shifting assembly 400 includes a right shifter dog 421 and a left shifter dog 411. When the right shifter dog 421 moves leftward, the right side portion 2200 abuts against the lower side wall 1100 of the workpiece 1000. When the left shifter dog 411 moves rightward, the left side portion 2100 abuts against the lower side wall 1100 of the workpiece 1000. The right shifter dog 421 is located to the left of the left shifter dog 411. In actual use, the right shifter dog 421 can be used first, adjusted to the right side of the right side portion 2200, then moved leftward to abut the right side portion 2200 against the lower side wall 1100 of the workpiece 1000. The left shifter dog 411 can then be adjusted to the left side of the left side portion 2100, and finally moved rightward to abut the left side portion 2100 against the lower side wall 1100 of the workpiece 1000. Alternatively, the left shifter dog 411 can be used first.

[0065] In some embodiments, the right pusher dog 421 in its initial position is positioned below the workpiece 1000 and at a predetermined distance from the workpiece 1000. Before moving leftward, the right pusher dog 421 first moves upward to a position in contact with the workpiece 1000. Specifically, the predetermined distance can be set based on the length of the right side portion 2200, and the predetermined distance can be greater than the length of the right side portion 2200 below the lower sidewall 1100. This arrangement provides clearance for the suction head 300 to move the workpiece 1000 and the right side portion 2200.

[0066] In its initial position, the left pusher dog 411 is positioned below the workpiece 1000 and at a predetermined distance from the workpiece 1000. Before moving rightward, the left pusher dog 411 first moves upward to a position in contact with the workpiece 1000. Specifically, the predetermined distance can be set based on the length of the left side portion 2100, and the predetermined distance can be greater than the length of the left side portion 2100 below the lower sidewall 1100. This arrangement provides clearance for the suction head 300 to move the workpiece 1000 and the left side portion 2100.

[0067] In some embodiments, to improve the application effect and avoid wrinkles in the protective film 2000 during the application process, the protective film 2000 can be bent as a whole before application. Specifically, during the application process, the right finger 421 first moves the right side portion 2200 away from one end of the lower side wall 1100 of the workpiece 1000, causing the right side portion 2200 to tilt leftward from top to bottom, and then abuts against the lower side wall 1100 of the workpiece 1000 and moves leftward to attach the right side portion 2200 to the lower side wall 1100 of the workpiece 1000. During the application process, the left finger 411 first moves the left side portion 2100 away from one end of the lower side wall 1100 of the workpiece 1000, causing the left side portion 2100 to tilt rightward from top to bottom, and then abuts against the lower side wall 1100 of the workpiece 1000 and moves rightward to attach the left side portion 2100 to the lower side wall 1100 of the workpiece 1000.

[0068] Furthermore, the right pusher dog 421 is resilient, and during the shifting process, the shifting end of the right pusher dog 421 tilts rightward from bottom to top. Specifically, before the right pusher dog 421 moves leftward, the upper end of the right pusher dog 421 vertically extends beyond the lower sidewall 1100 and is positioned above the lower sidewall 1100. This arrangement ensures that the right side portion 2200 is firmly pressed by the right pusher dog 421 during the bending process, tightly adhering to the corner between the right sidewall and the lower sidewall 1100 of the workpiece 1000, thereby preventing bubbles from forming at the corner and also preventing bubbles from forming on the lower sidewall 1100.

[0069] The left pusher dog 411 is resilient, and during the shifting process, the shifting end of the left pusher dog 411 tilts leftward from bottom to top. Specifically, before the left pusher dog 411 moves leftward, the upper end of the left pusher dog 411 vertically extends beyond the lower sidewall 1100 and is positioned above the lower sidewall 1100. This arrangement ensures that the left side portion 2100 is firmly pressed by the left pusher dog 411 during the bending process, tightly adhering to the corner between the left sidewall and the lower sidewall 1100 of the workpiece 1000, preventing bubbles from forming at the corner and also preventing bubbles from forming on the lower sidewall 1100.

[0070] In some embodiments, the toggle assembly 400 includes a left lifting drive member 413, a right lifting drive member 423, a transverse member 420 and a transverse drive member 430, wherein the transverse member 420 is arranged on the frame 100 for sliding along the X direction, the transverse drive member 430 is arranged on the frame 100 and is in transmission connection with the transverse member 420, and the transverse drive member 430 is used to drive the transverse member 420 to slide, the left lifting drive member 413 and the right lifting drive member 423 are both arranged on the transverse member 420, and the left shift claw 411 is arranged on the left lifting drive member The right shifter 421 is located at the output end of the right lifting member 423. The left lifting member 413 is used to drive the left shifter 411 to move along the Z direction between a left shifting position and a left avoidance position. The right lifting member 423 is used to drive the right shifter 421 to move along the Z direction between a right shifting position and a right avoidance position. The left shifter 411 in the left shifting position is higher than the right shifter 421 in the right avoidance position, and the right shifter 421 in the right shifting position is higher than the left shifter 411 in the left avoidance position. The transverse member 420 simultaneously drives the left and right shifters 411 and 421 to move left and right. When the left side portion 2100 is to be shifted, the left shifter 411 rises to the left shifting position, and the right shifter 421 descends to the right avoidance position. When the right side portion 2200 is to be shifted, the left shifter 411 descends to the left avoidance position, and the right shifter 421 rises to the right shifting position.

[0071] An adsorption mounting part 2301 is installed at the output end of the third moving component 230 , and the adsorption head 300 is installed on the adsorption mounting part 2301 .

[0072] The output end of the left lifting drive member 413 is provided with a left toggle platform 412, and the left shifter claw 411 is provided on the left toggle platform 412. The output end of the right lifting drive member 423 is provided with a right toggle platform 422, and the right shifter claw 421 is provided on the right toggle platform 422.

[0073] During the feeding process of the workpiece 1000, it needs to be transferred, and the position of the workpiece 1000 will change during the transfer process. To this end, in some embodiments, the first moving assembly 210 transfers the workpiece 1000 from the loading assembly 710 to the positioning assembly 740 for positioning the workpiece 1000 in the X and Y directions. The linear module then transfers the workpiece 1000 to the carrier located at the loading position 121 of the transmission assembly 500. The transmission assembly 500 transfers the carrier to the first assembly position 122 via the linear module. This arrangement improves the positioning accuracy of the workpiece 1000 when it is moved to the first assembly position 122.

[0074] The transport assembly 500 includes an upward track 510 and a downward track 520. The transfer of a carrier from the loading position 121 to the unloading position 125 is completed on the upward track 510. After a workpiece 1000 is removed from the carrier, the empty carrier returns via the downward track 520 and can be transferred again to the loading position 121 on the upward track 510. This arrangement allows for the recycling of carriers, reduces the number of carriers required, and lowers operating costs.

[0075] Specifically, the transmission component 500 includes a first track changing component 530 and a second track changing component 540, wherein the first track changing component 530 is used to move the carrier on the down track 520 to the up track 510, and the second track changing component 540 is used to move the carrier on the up track 510 to the down track 520.

[0076] Specifically, regarding the structure of the first track-changing assembly 530, in some embodiments, the first track-changing assembly 530 includes a first track-changing base, a first lateral pushing assembly and a first longitudinal pushing assembly, the first track-changing base is provided with a first initial position and a first change position, the down track 520 can transfer the carrier to the first initial position, the first lateral pushing assembly is provided on the first track-changing base, and is used to push the carrier located at the first initial position to the first change position, and the first longitudinal pushing assembly is provided on the frame 100, and is used to push the carrier located at the first change position to the up track 510. It should be noted that when the carrier moves to the down track 520 close to the first track-changing assembly 530, it is automatically transferred to the first initial position by the down track 520, and the first initial position and the first change position are spaced apart along the Y direction. With the help of the above-mentioned structure, the carrier enters the up track 510 from the down track 520 in the same posture after changing the two positions.

[0080] The loading assembly 710 supplies trays containing workpieces 1000 one by one to the feeding station. The first moving assembly 210 transfers the workpieces 1000 from the feeding station to the positioning assembly 740. When the last tray of the loading assembly 710 moves to the feeding station, the first moving assembly 210 alternately moves some of the workpieces 1000 in that tray to the temporary storage assembly 750 and the positioning assembly 740. This arrangement helps ensure the continuity of the material replacement process. Specifically, when the positioning assembly 740 is empty, the workpiece 1000 on the last tray is placed on the positioning assembly 740. During the positioning process of the positioning assembly 740, the workpiece 1000 on the last tray is placed on the temporary storage assembly 750. Since the speed at which the first moving component 210 transfers the workpiece 1000 is faster than the positioning speed of the positioning component 740, most of the workpieces 1000 in the last tray are transferred to the temporary storage component 750. On this basis, the number of workstations of the temporary storage component 750 for placing the workpiece 1000 can be the same as the number of workstations of the tray.

[0081] The protective film 2000 is moved to the first detection component 810 by the second moving component 220 to detect whether the protective film 2000 is wrinkled. If it fails, the protective film 2000 is moved to the waste barrel. If it passes, the relative position of the protective film 2000 and the second moving component 220 is detected. If it fails, when it moves to the first assembly position 122, the position compensation of the second moving component 220 is performed to ensure that the relative position of the protective film 2000 and the workpiece 1000 is within the error range. The above-mentioned setting improves the pass rate of the protective film 2000 attached to the workpiece 1000, thereby improving the success rate of film attachment; unqualified protective films 2000 are discarded at the source, thereby avoiding waste in subsequent processes and saving efficiency. In this embodiment, the second moving component 220 is a robot, and the output end of the robot can reasonably adjust the position according to the detection information, so that the docking accuracy of the protective film 2000 and the workpiece 1000 meets the requirements.

[0082] After the protective film 2000 is applied at the first assembly station 122, the workpiece 1000 is transferred to the first transfer station 123 via the transport assembly 500.

This arrangement allows the force of the transfer head 600 on the protective film 2000 to be provided by the transfer elastic member 610, thereby preventing the protective film 2000 from being damaged due to excessive force. The mounting end of the transfer head 600 is a T-shaped structure, and the fixing member is fixed to the transfer base 2201. The fixing member is provided with an inverted T-shaped groove, and the mounting end of the transfer head 600 is slidably arranged in the inverted T-shaped groove.

[0085] After the film is pasted, the workpiece 1000 is transferred from the first transfer position 123 to the second transfer position 124 by the transmission component 500, and the workpiece 1000 is moved to the second detection component 820 by the fourth moving component 240 for film testing.

The workpiece 1000 with unqualified film pasting is moved to the waste component 770, and the workpiece 1000 with qualified film pasting is transferred to the receiving component 730.

[0086] During the above process, the workpiece 1000 is first inspected by the second inspection assembly 820 at the protective film 2000 on the lower sidewall 1100. After flipping 180°, the workpiece 1000 is again inspected by the second inspection assembly 820 at the protective film 2000 on the upper sidewall. In this embodiment, the film laminating device includes a flip assembly 760, which is disposed on the frame 100 and is used to flip the workpiece 1000 located at the unloading position 125 180°, placing the workpiece 1000 in the flip position.
