Technical Field
[0001] This utility model relates to the technical field of applying adhesive film to the V-shaped surface of a part, and in particular to a film-applying device for applying adhesive film to the V-shaped surface of a part. Background Technology
[0002] The structure of the parts produced in a certain workshop is as follows: Figures 1-3 As shown, it includes a base 1, two support plates 2 are fixed on the bottom surface of the base 1, a horizontal surface 3 and an inclined surface 4 that is connected to the horizontal surface 3 are opened on the top surface of the base 1, the inclined surface 4 and the horizontal surface 3 form a V-shaped surface, and a boss 5 is fixed on the top surface of the V-shaped surface.
[0003] The process requires that an adhesive film 6 be pasted on the top surface of the V-shaped surface of the part, such as... Figure 3 The diagram shows the structure of a part with adhesive film 6 pasted on it. The method by which the worker pastes adhesive film 6 onto the V-shaped surface of the part is as follows: S1. The worker takes out a part and places the support plate 2 of the part on the table surface. S2, The worker takes out a... Figures 4-5 The composite membrane shown includes a cover film 7 and an adhesive film 6. The low-tack side of the adhesive film 6 is adhered to the bottom surface of the cover film 7, and the high-tack side of the adhesive film 6 is exposed to the outside. A through groove A8 is formed in the middle of the adhesive film 6, and a through groove B9 connected to the through groove A8 is formed in the middle of the cover film 7. Three through holes 10 are formed inside the cover film 7 and distributed on the outer edge of the through groove B9. S3. The worker places the through groove A8 of the adhesive film 6 of the composite film onto the outside of the boss 5 of the part, such as... Figure 6 As shown, the high-tack surface of the adhesive film 6 is then brought into contact with the V-shaped surface of the part; then the worker presses down on the top surface of the cover film 7 of the composite film by hand, so that the high-tack surface of the adhesive film 6 is tightly bonded to the V-shaped surface of the part. S4. The worker tears off the cover film 7 of the composite film to separate the cover film 7 from the low-tack side of the adhesive film 6, thus finally achieving the adhesion of an adhesive film 6 to the V-shaped surface of the first part, as shown. Figure 7 As shown; S5. Workers repeat steps S1 to S4 multiple times to apply an adhesive film to the V-shaped surface of multiple parts.
[0004] However, although the method used in the workshop can adhere an adhesive film 6 to the V-shaped surface of the part, the following technical defects still exist in actual operation: I. In step S3, the worker needs to apply pressure to the cover film 7 of the composite film by hand so that the highly viscous side of the adhesive film 6 is tightly bonded to the V-shaped surface of the part. However, the pressure applied manually is uneven, which causes air bubbles to exist between the adhesive film 6 and the V-shaped surface of the part after the film is applied, thereby reducing the quality of the adhesive film being bonded to the V-shaped surface of the part.
[0005] II. In step S4, workers also need to manually tear the cover film 7 of the composite film off the adhesive film 6 and throw the torn cover film 7 into the waste bin; the entire operation is done manually by workers, which undoubtedly increases the workload of workers.
[0006] Therefore, there is an urgent need for a film-applying device that can greatly reduce the workload of workers and improve the quality of applying adhesive film to the V-shaped surface of parts. Utility Model Content
[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a film-applying device for applying adhesive film to the V-shaped surface of parts, which greatly reduces the labor intensity of workers and improves the quality of applying adhesive film to the V-shaped surface of parts.

A pressure block is fixed on the bottom surface of the connecting plate. A contoured surface that matches the V-shaped surface of the part is formed on the bottom surface of the pressure block. A receiving groove is formed on the bottom surface of the contoured surface. Notches are formed at the four corners of the pressure block. Suction heads are fixed on the bottom surface of the four notches. Four L-shaped air channels are formed inside the pressure block. The end ports of the four L-shaped air channels are respectively connected to the four suction heads. A vacuum pump is connected to the first port of each of the four L-shaped air channels via a hose.
[0009] Support legs, which are fixed to the ground, are installed on the bottom surface of the platform at its four corners.
[0010] A waste basket is placed below the platform, directly below the material chute.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 8-12 As shown, a film-applying device for attaching adhesive film to the V-shaped surface of a part includes a platform 11 and a pressure-applying and film-tearing assembly disposed on the platform 11 for applying pressure to the cover film 7 of the composite film and tearing the cover film 7 off the adhesive film 6. A sliding groove 12 penetrating its front end face is formed on the top surface of the platform 11. A material drop groove 13 penetrating the bottom surface of the platform 11 is formed at the bottom of the sliding groove 12. A pull-out plate 14 is slidably installed in the material drop groove 13. A pad 15 is fixed on the top surface of the pull-out plate 14. A positioning groove 16 for positioning the part is formed on the top surface of the pad 15. Three positioning posts 17 distributed on the outer edge of the positioning groove 16 are fixed on the top surface of the pad 15. The diameter of the positioning post 17 is equal to the diameter of the through hole 10 of the cover film 7 of the composite film. The horizontal width of the positioning groove 16 of the pad 15 is equal to the distance between the two support plates 2 of the part.
[0017] The pressurizing and film-tearing assembly includes a vertical plate 18 fixed on the platform 11 and located behind the slide 12. A pressurizing cylinder 19 is fixed on the front end of the vertical plate 18. A connecting plate is fixed on the working end of the piston rod of the pressurizing cylinder 19. A pressure block 20 is fixed on the bottom surface of the connecting plate. A contoured surface 21 that matches the V-shaped surface of the part is formed on the bottom surface of the pressure block 20. A receiving groove 22 is formed on the bottom surface of the contoured surface 21. Notches are formed at the four corners of the pressure block 20. Suction heads 23 are fixed on the bottom surface of the four notches. Four L-shaped air passages 24 are formed inside the pressure block 20. The end ports of the four L-shaped air passages 24 are respectively connected to the four suction heads 23. A vacuum pump is connected to the first port of each of the four L-shaped air passages 24 via a hose.
[0018] Support legs, which are fixed to the ground, are fixed on the bottom surface of the platform 11 at its four corners. A waste basket 25 is placed below the platform 11, directly below the material chute 13. A handle 26 is fixed on the front end face of the pull-out plate 14. The worker can pull the pull-out plate 14 forward by pulling the handle 26; the worker can push the pull-out plate 14 backward by pushing the handle 26 backward.
[0019] The working process of this utility model is as follows: S1, the worker takes out a... Figures 1-3 The part shown is positioned by placing its two support plates 2 into the positioning grooves 16 of the pad 15. Since the horizontal width of the positioning grooves 16 of the pad 15 is equal to the distance between the two support plates 2 of the part, the part is positioned accordingly. Figure 13 As shown, at this time, the base 1 of the part is supported on the top surface of the pad 15, and the boss 5 of the part faces upward. Positioning of S2 and film 6: The worker takes out a piece like... Figures 4-5 The composite film shown is positioned by fitting the through groove A8 of the adhesive film 6 onto the outside of the boss 5 of the part, and by fitting the three through holes 10 of the cover film 7 onto the outside of the three positioning posts 17, thereby achieving the positioning of the cover film 7 and, consequently, the positioning of the adhesive film 6. Figure 14 As shown, at this time, the highly viscous surface of the adhesive film 6 just covers the V-shaped surface of the part; S3. The worker pushes the pull-out plate 14 backward by hand. The pull-out plate 14 drives the pad 15 to move backward. The pad 15 drives the parts and composite film to move backward synchronously. When the pull-out plate 14 is blocked by the rear end face of the slide groove 12, the cover film 7 of the composite film is just in the pressure position of the pressure block 20. Figure 15 As shown; S4. The piston rod of the pressurizing cylinder 19 extends downward, causing the connecting plate and the pressure block 20 to move downward synchronously. The pressure block 20 moves towards the cover film 7. When the piston rod of the pressurizing cylinder 19 is fully extended, the pressure block 20 presses against the top surface of the cover film 7. Figure 16 As shown, the contoured surface 21 of the pressure block 20 matches the V-shaped surface of the part, so that the high-adhesion surface of the adhesive film 6 is tightly bonded to the V-shaped surface of the part, while the bottom surface of the suction head 23 is in contact with the top surface of the cover film 7. As seen in steps S3-S4, the worker only needs to control the piston rod of the pressurizing cylinder 19 to extend downwards, allowing the contoured surface 21 of the pressure block 20 to mate with the V-shaped surface of the part, thereby tightly adhering the high-adhesion surface of the composite film 6 to the V-shaped surface of the part. Therefore, compared to manual application, this film-applying device allows the adhesive film 6 to be adhered more evenly to the V-shaped surface of the part, effectively preventing air bubbles from forming between the adhesive film 6 and the V-shaped surface of the part, thus greatly improving the quality of adhesive film adhesion to the V-shaped surface of the part.
[0020] S5. Control the vacuum pump to start. The vacuum pump evacuates the L-shaped air passage 24 and the suction head 23. Under negative pressure, the cover film 7 is adsorbed and fixed on the suction head 23. S6. The piston rod of the pressurizing cylinder 19 retracts upward, causing the connecting plate and pressure block 20 to move upward synchronously. The pressure block 20 then moves the suction head 23 upward, which in turn moves the cover film 7 upward, gradually separating the cover film 7 from the adhesive film 6. When the piston rod of the pressurizing cylinder 19 is fully retracted, the cover film 7 is thus peeled off the adhesive film 6. Figure 17 As shown, this ultimately resulted in the application of an adhesive film 6 to the V-shaped surface of the first part; S7. The worker pulls the pull-out plate 14 forward by hand. The pull-out plate 14 moves the pad 15 forward, and the pad 15 moves the part with the adhesive film 6 attached to it forward synchronously. Then the worker removes the part with the adhesive film 6 attached to it from the pad 15 in the following direction. Figure 17 As indicated by the middle arrow; S8. Disposal of the torn-off cover film 7: The worker controls the piston rod of the pressurizing cylinder 19 to extend downwards. The piston rod drives the pressure block 20 to move downwards, and the pressure block 20 drives the cover film 7 to move downwards. The cover film 7 moves towards the material drop chute 13 of the platform 11. When the piston rod of the pressurizing cylinder 19 is fully extended, the vacuum pump is turned off. The suction head 23 no longer adheres to the cover film 7, and the cover film 7 falls off the suction head 23. The fallen cover film 7 passes through the material drop chute 13 and falls into the waste basket 25. S9. Workers repeat steps S1 to S8 multiple times to apply an adhesive film 6 to the V-shaped surface of multiple parts.
[0021] In step S6, the cover film 7 is automatically torn off from the adhesive film 6. In step S8, the torn cover film 7 is automatically thrown into the waste bin 25. This eliminates the need for workers to manually tear the cover film 7 or throw it into the waste bin 25, thus greatly reducing the workload of workers.
