The entire adhesive film 9 is composed of a plurality of slender films in the middle and waste films on the front and rear surfaces. The film laminating mechanism 4 is fixed to the bottom end of the support frame 3 so that the bottom of the film laminating mechanism 4 can contact the surface of the jig 2, thereby pressing the material strip and the adhesive film 9 onto the jig 2.

[0030] The support frame 3 is also provided with a film 9 retracting and releasing mechanism 7 and a pressure wheel transmission assembly 6 for pulling the film 9. The waste film at both ends of the slender film is removed by the film 9 retracting and releasing mechanism 7 so that the slender film can be pasted on the steel belt 8. The film pasting mechanism 4 includes a pressing block 41 placed above the jig 2 and a tongue block 42 movably connected to the inside of the pressing block 41. The film 9 passes through the bottom of the pressing block 41 and is connected to the pressure wheel transmission assembly 6. The pressing block 41 moves down with the liftable support frame 3 to press the steel belt 8 and the film 9. The tongue block 42 is used to push out the slender film on the film 9 and press it on the steel belt 8.

[0031] Please refer to the attached Figure 3 -Attached Figure 7 As shown, the machine 1 is also provided with a driving cylinder 10, the telescopic end of the driving cylinder 10 is fixedly connected to the support frame 3, and the driving cylinder 10 drives the support frame 3 and the film-sticking mechanism 4 to move up and down to press the steel strip 8 and the adhesive film 9; the film-sticking mechanism 4 also includes a first lifting cylinder 44 fixed on the pressing block 41 and a through groove 43 opened on the pressing block 41, the tongue block 42 is placed in the through groove 43, and the telescopic end of the first lifting cylinder 44 is fixedly connected to the tongue block 42, and the tongue block 42 is driven by the first lifting cylinder 44 to move back and forth along the vertical direction of the through groove 43, thereby pushing out the slender film on the adhesive film 9 and pressing it on the steel strip 8, and the shape of the bottom of the tongue block 42 is the same as the shape of the slender film, so that the slender film can be completely attached to the steel strip 8.

[0032] In the above embodiment, preferably, the film sticking mechanism 4 also includes a top block 45 placed directly below the pressure block 41 and a second lifting cylinder 46 for driving the top block 45 to move up and down. The steel belt 8 and the adhesive film 9 are clamped by the cooperation of the top block 45 and the pressure block 41, and a guide pin 47 is provided on the top block 45.

[0033] Specifically, the steel belt 8 is driven on the jig 2, and the film 9 passes through the bottom of the pressing block 41 and is driven by the pressing wheel transmission assembly 6, wherein the transmission direction of the film 9 is as shown in the attached Figure 4 As shown, the driving cylinder 10 drives the support frame 3 to move downward, and the support frame 3 then drives the pressure block 41 to move downward. At the same time, the second lifting cylinder 46 under the fixture 2 drives the top block 45 to move upward, and the guide pins 47 on the top block 45 are inserted into the positioning holes on the steel belt 8 to fix the steel belt 8 to prevent the steel belt 8 from shifting. The pressure block 41 cooperates with the top block 45 to press the steel belt 8 and the adhesive film 9 therebetween, thereby making the slender film on the adhesive film 9 stick to the steel belt 8; then, the support frame 3 drives the pressure block 41 and the adhesive film 9 to move upward, but in order to prevent the adhesive film 9 from moving upward with the slender film that has been attached to the steel belt 8 during the upward movement, therefore, during the upward movement of the pressure block 41, the first lifting cylinder 44 drives the tongue block 42 to move downward to abut and press on the slender film and the steel belt 8, thereby increasing the stability of the slender film fitting, and then the second lifting cylinder 46 drives the top block 45 to move downward again.

[0034] In the above embodiments, preferably, as shown in the attached Figure 4As shown, the film 9 retracting and releasing mechanism 7 includes a reel 1 71, a reel 2 72 and a reel 3 73 which are synchronously rotated by a motor. The slender film to be used is placed in the middle of the film 9, and the two sides of the slender film are the front waste film and the rear waste film. The reel 1 71 is used to place the complete film 9, and the reel 2 72 and the reel 3 73 are used to collect the waste film on both sides of the slender film, wherein the reel 2 72 is used to collect the front waste film first, and then the slender film is attached to the steel belt 8 through the film attachment mechanism 4, and the remaining rear waste film is reeled by the reel 3 73.

[0035] In the above embodiment, preferably, in order to fit the direction of the adhesive film 9, the pressing block 41 is a V-shaped pressing block 41, and both sides of the bottom of the V-shaped pressing block 41 adopt an R chamfered structure to prevent the bottom edge of the pressing block 41 from damaging or scratching the adhesive film 9 or the slender film. A pressure regulating valve connected to the first lifting cylinder 44 is provided in the machine 1, and the downward pressure of the top block 45 is controlled by the pressure regulating valve to prevent the steel belt 8 from being deformed.

[0036] As attached Figure 6 As shown, the pressure wheel transmission assembly 6 includes a driving wheel 61 fixedly connected to the output end of the motor and a driven wheel 62 fixed obliquely above the driving wheel 61. After the adhesive film 9 is pasted, a layer of rear waste mold remains. The rear waste mold passes through the driving wheel 61 and the driven wheel 62. The driving wheel 61 and the driven wheel 62 are driven to rotate by the motor, thereby driving the adhesive film 9 or the rear waste mold placed on the driving wheel 61 and the driven wheel 62 for transmission.

[0037] In the above embodiment, preferably, in order to prevent the adhesive film 9 from shifting during the transmission process and causing the slender film on the adhesive film 9 to be skewed, positioning protrusions 63 are provided in the circumferential direction of both ends of the active wheel 61, and positioning holes cooperating with the positioning protrusions 63 are provided on both sides of the adhesive film 9. When the active wheel 61 and the driven wheel 62 drive the adhesive film 9 to transmit, the positioning protrusions 63 are inserted into the positioning holes to prevent shifting. At the same time, an adhesive film optical fiber sensor 11 for edge finding is fixed above the active wheel 61, and the adhesive film optical fiber sensor 11 is aligned with the positioning hole on the adhesive film 9 (not shown in the accompanying drawings). If the optical fiber can pass through the positioning hole, it means that the adhesive film 9 has not shifted. If the optical fiber does not pass through the positioning hole, it means that the adhesive film 9 may shift, and an alarm is triggered in time to remind the staff to make corrections.

[0038] Please refer to the attached Figure 8 -Attached Fig.10The pulling mechanism 5 is placed at the discharge end of the fixture 2.
