[0001] This utility model relates to the technical field of circuit film conveying equipment, specifically, a circuit film feeding device with the function of removing debris. Background Technology

[0002] The keyboard typically contains a main membrane circuit board, which is quite flexible. During the manufacturing process, an insulating film is usually covered on the membrane circuit board to insulate the circuits. However, before the insulating film is applied, the surface of the membrane circuit board is easily contaminated with debris generated during production. This debris can easily cause insulation failure after the insulating film is applied, thus affecting product quality. Utility Model Content

The vibrating debris removal conveyor includes a roller frame connected to the machine body, an active roller and a passive roller are respectively installed on the roller frame, and multiple elastic conveying strips are wound around the active roller and the passive roller, forming a debris dropping area between two adjacent elastic conveying strips.

[0005] In the aforementioned circuit film feeding device with debris removal function, both the active roller and the passive roller are provided with multiple annular grooves, and the elastic conveying strip is wound around the annular grooves.

[0006] In the aforementioned circuit film feeding device with debris removal function, the elastic conveyor strip is made of silicone.

[0007] In the aforementioned circuit film feeding device with debris removal function, the circuit film stacking section includes a stacking frame installed at one end of the machine body. A transverse groove is provided in the stacking frame. Two sliding plates are movably installed on the transverse groove. A positioning plate is provided on one side of the two sliding plates. A stacking area is formed between the two positioning plates. A suction component is provided above the vibrating debris removal conveyor. The suction component corresponds to the stacking area.

[0008] According to the claim, a circuit film feeding device with debris removal function is characterized in that the slide plate is mounted on the transverse groove by locking bolts.

[0009] In the above-mentioned circuit film feeding device with debris removal function, the suction component includes a support frame installed on both sides of the machine body, a top plate installed on the support frame, and a suction cup fixing seat that can move back and forth and up and down is provided at one end of the top plate near the stacking area. Multiple negative pressure suction cups are detachably installed on the suction cup fixing seat.

[0010] In the above-mentioned circuit film feeding device with debris removal function, guide rods are installed on both sides of the upper end of the top plate, and sliders are sleeved on the guide rods. A lifting cylinder is installed on the side of the slider near the stacking area, and the suction cup fixing seat is connected to the cylinder shaft of the lifting cylinder.

[0011] In the aforementioned circuit film feeding device with debris removal function, a push cylinder mounted on the top plate is provided between the guide rods on both sides, and the cylinder shaft of the push cylinder is connected to the slider.

[0012] In the aforementioned circuit film feeding device with debris removal function, a groove is provided on the suction cup fixing seat, and a suction cup base plate is installed on the groove by bolts, and the negative pressure suction cup is installed on the suction cup base plate.

[0013] The beneficial effects of this invention are as follows: During the operation of multiple elastic conveyor strips between the active roller and the passive roller, each elastic conveyor strip is elastic, causing continuous tension changes between the elastic conveyor strips between the active roller and the passive roller. When the film circuit board is placed on the surface of the multiple elastic conveyor strips for conveying, the film circuit board exhibits a slight bouncing phenomenon on the surface of the multiple elastic conveyor strips, causing vibration during the conveying process of the film circuit board. This causes debris on the surface of the film circuit board to fall off from the debris drop area, preventing the debris from being covered during subsequent lamination and thus reducing the quality of the product.

Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Combination Figures 1 to 3 The circuit film feeding device shown includes a body 1, with a circuit film stacking section at one end of the body 1. A vibrating debris-removing conveyor 3 is provided on one side of the circuit film stacking section, and a conveyor 4 is provided on the side of the vibrating debris-removing conveyor 3 away from the circuit film stacking section. The vibrating debris-removing conveyor 3 includes a roller frame 10 connected to the body 1. A drive roller 11 and a driven roller 12 are respectively mounted on the roller frame 10. Multiple elastic conveying strips 14 are wound around the drive roller 11 and the driven roller 12, and a debris-falling area is formed between two adjacent elastic conveying strips 14. This embodiment During the operation of multiple elastic conveyor strips 14 between the active roller 11 and the passive roller 12, the tension of each elastic conveyor strip 14 constantly changes due to its elasticity. When the thin film circuit board is placed on the surface of the multiple elastic conveyor strips 14 for conveying, the thin film circuit board exhibits a slight bouncing phenomenon on the surface of the multiple elastic conveyor strips 14, causing vibration during the conveying process. This causes debris on the surface of the thin film circuit board to fall off from the debris drop area, preventing the debris from being covered during subsequent lamination and thus reducing the quality of the product.

[0020] In this embodiment, both the active roller 11 and the passive roller 12 are provided with multiple annular grooves 13, and the elastic conveying strip 14 is wound around the annular grooves 13; this can prevent the elastic conveying strip 14 from shifting position during operation.

[0021] It is worth noting that the elastic conveyor strip 14 in this embodiment is made of silicone.

[0022] The circuit film stacking section of this embodiment includes a stacking frame 2 installed at one end of the machine body 1. A transverse groove 5 is provided in the stacking frame 2. Two slide plates 6 are movably installed on the transverse groove 5. A positioning plate 7 is provided on one side of the two slide plates 6. A stacking area is formed between the two positioning plates 7. A suction component 9 is provided above the vibrating debris removal conveyor 3. The suction component 9 corresponds to the stacking area. Multiple thin film circuit boards can be placed in the stacking area so that the suction component 9 can adsorb the thin film circuit boards and place them on the vibrating debris removal conveyor 3 for vibrating conveying.

[0023] The slide plate 6 is mounted on the transverse groove 5 by locking bolts; the position of the slide plate 6 on the transverse groove 5 can be adjusted by loosening or tightening the locking bolts, thereby adjusting the size of the stacking area to better accommodate the positioning and placement of thin film circuit boards of different sizes.

[0024] The suction assembly 9 in this embodiment includes a support frame 8 installed on both sides of the machine body 1. A top plate 15 is installed on the support frame 8.

Multiple negative pressure suction cups 23 are detachably installed on the suction cup fixing seat 20. The film circuit board can be adsorbed and placed onto the vibrating debris conveyor 3 by the multiple negative pressure suction cups 23 that can move back and forth and up and down.

[0025] Specifically, guide rods 16 are installed on both sides of the upper end of the top plate 15. A slider 17 is sleeved on the guide rod 16. A lifting cylinder 19 is installed on the side of the slider 17 near the stacking area. The suction cup fixing seat 20 is connected to the cylinder shaft of the lifting cylinder 19. The lifting cylinder 19 can be driven to move back and forth by the slider 17. At the same time, the lifting cylinder 19 can drive multiple negative pressure suction cups 23 to lift synchronously, so as to transfer the thin film circuit board to the vibrating debris removal conveyor 3 after adsorbing it.

[0026] It is worth noting that a push cylinder 18 is installed on the top plate 15 between the two guide rods 16. The cylinder shaft of the push cylinder 18 is connected to the slider 17. The slider 17 can be moved back and forth by pushing the cylinder 18, and the response is fast.
