Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic product processing, in particular to a flow switching film tearing device. BACKGROUND

[0002] In the production and manufacturing process of electronic products, the protective film of the spare part needs to be torn off to facilitate subsequent other processing. The current film tearing method used in the industry is mainly mechanical hand film tearing, which has high automation degree and high film tearing efficiency.

For some double-layer film structure products, the connection strength between the product and the different protective films is not the same. Using the same pressure for different protective films may cause the product to be pulled away instead of tearing off the protective film due to excessive film tearing resistance, which is unstable and cannot ensure the film tearing quality. SUMMARY

[0004] Based on this, the present application provides a flow switching film tearing device, which has a reasonable structure and is convenient to use. The product is switched between the inner film tearing assembly and the outer film tearing assembly through the flow assembly, which facilitates the tearing of the inner film and the outer film, and greatly improves the film tearing quality.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Please see Figures 1 to 9 This invention provides a transfer and switching film-tearing device, comprising a transfer assembly 10, an inner film tearing assembly 20 mounted at one end of the transfer assembly 10, and an outer film tearing assembly 30 mounted at the other end of the transfer assembly 10. The transfer assembly 10 is used to transport the product 40. Figure 10 As shown, an inner film 41 is attached to the middle of the product 40, and an outer film 42 is attached to the periphery of the product 40; the inner film 41 and the outer film 42 are spaced apart, and the body of the product 40 is exposed between the inner film 41 and the outer film 42. The exposed body of the product 40 is used to be adsorbed onto the transfer assembly 10.

[0037] The transfer assembly 10 includes a fixed base 11, a first feeder 12 slidably connected to one side of the fixed base 11, a second feeder 13 slidably connected to the other side of the fixed base 11, a guide plate 14 connected to the bottom of the fixed base 11, a synchronous belt 15 mounted on the top of the fixed base 11, and a drive motor 16 connected to the synchronous belt 15. The guide plate 14 abuts against the bottom end of the second feeder 13. The first feeder 12 is fixedly connected to one side of the synchronous belt 15, and the second feeder 13 is fixedly connected to the other side of the synchronous belt 15. As the drive motor 16 rotates forward and backward, the first feeder 12 and the second feeder 13 can be controlled to reciprocate along the length of the fixed base 11.

[0038] The top surface of the first suction device 12 is provided with a first suction disc 120, and the top surface of the second suction device 13 is provided with a second suction disc 130. The first suction disc 120 and the second suction disc 130 are used to suck the body of the product 40 exposed between the inner film 41 and the outer film 42, and at this time, the inner film 41 and the outer film 42 are both directed towards the fixed base 11. In this embodiment, when located at opposite ends of the fixed base 11, the suction surface of the first suction disc 120 and the suction surface of the second suction disc 130 are located on the same plane, so as to facilitate the film tearing of the inner film tearing assembly 20 and the outer film tearing assembly 30 respectively. When located at the middle of the fixed base 11, the second suction device 13 can drive the second suction disc 130 to rise, so that the first suction disc 120 and the second suction disc 130 are staggered in height with each other.

[0039] Specifically, as shown in Figure 3 and Figure 4 , the second suction device 13 includes a base 131 slidingly connected to the fixed base 11, a lifting base 132 slidingly connected to the base 131, a pulley 133 installed at the bottom end of the lifting base 132, and a tension spring 134 connecting the base 131 and the lifting base 132. The tension spring 134 is used to drive the lifting base 132 to abut against the base 131, and the base 131 is also used to connect the synchronous belt 15. The pulley 133 abuts against the top of the guide plate 14, and the second suction disc 130 is installed on the top surface of the lifting base 132.

[0040] Specifically, the base 131 and the lifting base 132 are slidingly connected through a guide rail pair, and the movement direction of the lifting base 132 is perpendicular to the length direction of the fixed base 11.

[0041] In this embodiment, the guide plate 14 is substantially arranged in a "convex" shape, and the height of the middle part of the guide plate 14 is greater than the height of the opposite ends of the guide plate 14. The height position of the base 131 is always unchanged, when the second suction device 13 gradually moves to the middle part of the guide plate 14, the lifting base 132 and the second suction disc 130 are lifted up, so that the first suction disc 120 and the second suction disc 130 are staggered in height with each other, which can effectively avoid the interference or collision between the two products 40, greatly improve the flow efficiency of the product 40, and facilitate the film tearing between the inner film tearing assembly 20 and the outer film tearing assembly 30. When the second suction device 13 gradually moves from the middle part of the guide plate 14 to any one end of the guide plate 14, the lifting base 132 and the second suction disc 130 fall down, and under the action of the tension spring 134, the lifting base 132 abuts against the base 131, and the second suction disc 130 is completely reset, so that when at any one end of the guide plate 14, the suction surface of the first suction disc 120 and the suction surface of the second suction disc 130 remain on the same plane, so as to facilitate the film tearing of the inner film tearing assembly 20 and the outer film tearing assembly 30 respectively.

[0042] The inner film tearing assembly 20 comprises an inner film tearing support 21 on one side of the fixed base 11, an inclined sliding table cylinder 22 installed on the inner film tearing support 21, a moving plate 23 connected to the inclined sliding table cylinder 22, a rotating shaft 24 rotatably installed on one end of the moving plate 23, inner film tearing clamps 25 fixedly installed on opposite ends of the rotating shaft 24, and a rotating shaft driving cylinder 26 connected to the middle part of the rotating shaft 24. The cylinder body of the rotating shaft driving cylinder 26 is fixedly installed on the moving plate 23, and the piston rod of the rotating shaft driving cylinder 26 is hingedly connected to the middle part of the rotating shaft 24 to drive the rotating shaft 24 to rotate, thereby driving the inner film tearing clamps 25 to rotate, so that the inner film tearing clamps 25 can be offset in a certain range of horizontal and vertical directions after clamping the inner film 41, so that a certain angle is formed between the inner film 41 and the surface of the product 40, and the inner film 41 is better torn off.

[0043] In this embodiment, the extension and retraction directions of the piston rods of the inclined sliding table cylinder 22 are arranged at an angle with the suction surfaces of the first and second suction cups 120 and 130, respectively.

[0044] When tearing the inner film, the inclined sliding table cylinder 22 drives the moving plate 23 to approach the product 40 at one end of the fixed base 11 until the inner film tearing clamps 25 just clamp the edge of the inner film 41, and then the inclined sliding table cylinder 22 drives the moving plate 23 to move away from the product 40, and at the same time, the piston rod of the rotating shaft driving cylinder 26 is shortened, so that a certain angle is formed between the inner film 41 and the surface of the product 40, and the inner film 41 is torn off as the inner film tearing clamps 25 gradually move away from the product 40.

[0045] The outer film tearing assembly 30 comprises an outer film tearing support 31 on one side of the fixed base 11, horizontal guide rail pairs 32 installed on opposite sides of the top of the outer film tearing support 31, vertical guide rail pairs 33 vertically connected to the horizontal guide rail pairs 32, outer film tearing clamps 34 and guide rollers 35 connected to one side of the vertical guide rail pairs 33, push cylinders 36 connected to the other side of the vertical guide rail pairs 33, and guide plates 37 slidingly connected to the guide rollers 35. The guide plates 37 are fixedly connected to the outer film tearing support 31.

[0046] In this embodiment, as shown in Figure 8 and Figure 9 The horizontal guide rail pairs 32 comprise horizontal guide rails 321 fixedly connected to the fixed base 11 and horizontal sliding blocks 322 matched with the horizontal guide rails 321. The vertical guide rail pairs 33 comprise vertical sliding blocks 331 fixedly connected to one side of the horizontal sliding blocks 322 and vertical guide rails 332 matched with the vertical sliding blocks 331. One side of the vertical sliding blocks 331 away from the horizontal sliding blocks 322 is used to connect the piston rods of the push cylinders 36, and the vertical guide rails 332 are used to bear the outer film tearing clamps 34.

[0047] In the embodiment, the guide plate 37 is provided with a guide groove 370 arranged in an arc shape, the height of the end of the guide groove 370 away from the fixed base 11 is greater than the height of the end of the guide groove 370 close to the fixed base 11; the guide groove 370 is used for accommodating the guide roller 35. When the push cylinder 36 drives the horizontal sliding block 322 to move, under the guidance of the guide groove 370, the vertical guide rail 332 will move in the vertical direction, so that the outer film tearing clamp jaw 34 can move in a certain range of horizontal direction and vertical direction after clamping the outer film 42, so that a certain angle is formed between the outer film 42 and the surface of the product 40, and the outer film 42 is better torn off.

[0048] In the embodiment, the outer film tearing carrier 31 comprises a horizontal sliding table cylinder 311, a vertical sliding table cylinder 312 connected with the horizontal sliding table cylinder 311, and a carrier plate 313 connected with the vertical sliding table cylinder 312; the opposite sides of the carrier plate 313 are respectively used for carrying the horizontal guide rail pair 32.

[0049] When the outer film is torn, the outer film tearing carrier 31 drives the carrier plate 313 to move close to the product 40 at one end of the fixed base 11, until the outer film tearing clamp jaw 34 just clamps the edge of the outer film 42, and then the push cylinder 36 is started to drive the horizontal sliding block 322 to move, under the guidance of the guide groove 370 (such as Figure 8 the direction of the arrow), the vertical guide rail 332 will move in the vertical direction, so that the outer film tearing clamp jaw 34 can move in a certain range of horizontal direction and vertical direction after clamping the outer film 42, so that a certain angle is formed between the outer film 42 and the surface of the product 40, and then the outer film tearing carrier 31 reversely drives the outer film tearing clamp jaw 34 to gradually move away from the product 40 to tear off the outer film 42.

[0050] Further, the flow switching and tearing film device further comprises a first digital pressure switch 51 and a second digital pressure switch 52 installed on one side of the inner film tearing assembly 20; the first digital pressure switch 51 is electrically connected with the inner film tearing clamp jaw 25 one by one, so as to control the tearing force of the inner film tearing clamp jaw 25 on the inner film 41; the second digital pressure switch 52 is electrically connected with the outer film tearing clamp jaw 34 one by one, so as to control the tearing force of the outer film tearing clamp jaw 34 on the outer film 42.

[0051] The flow switching and tearing film device has reasonable structure and is convenient to use, the cooperation of the second suction device 13 and the guide plate 14 makes the first suction disc 120 and the second suction disc 130 staggered in height, which facilitates switching different products 40 between the inner film tearing assembly 20 and the outer film tearing assembly 30, tearing off the inner film 41 and the outer film 42, and greatly improving the tearing film quality.

[0052] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as there is no conflict, any combination of the technical features should be considered within the scope of the present disclosure.
