Description

Technical Field

[0001] This utility model relates to the field of finished product pulling technology, and more specifically, to a flexible circuit board processing pulling mechanism. Background Technology

[0002] Flexible circuit boards, also known as flexographic circuit boards or flexible printed circuit boards, are favored for their excellent properties such as light weight, thinness, and free bending and folding. They are printed circuits with high reliability and excellent flexibility, made from polyester film or polyimide as the substrate. By embedding circuit designs into a flexible, thin plastic sheet, a large number of precision components can be packed into narrow and limited spaces, thus forming a flexible circuit. This type of circuit can be bent and folded at will, is lightweight, small in size, has good heat dissipation, and is easy to install, breaking through the limitations of traditional interconnection technology. During the processing and manufacturing of flexible circuit boards, a pulling mechanism is required to pull the finished product after the substrate has been processed.

[0003] Most existing material pulling mechanisms use drive rollers as the rotation source. With the cooperation of pressure rollers and drive rollers, they pull one end of the finished product processed from the substrate, which is convenient for conveying and winding. However, in actual production, the distance between pressure rollers and drive rollers is mostly fixed, making it inconvenient to adjust the distance for installation or replacement of substrates. Although there are adjustment mechanisms that adjust the distance between pressure rollers and drive rollers by pushing with bolts, the extrusion intensity cannot be precisely controlled, which can easily lead to damage to the finished product and affect the material pulling effect.

[0010] Preferably, the output end of the first electric push rod passes through the middle of the slot, and the nut is located on the side of the second support plate away from the first electric push rod and the first support plate.

[0011] Preferably, two auxiliary plates are fixedly connected to the middle of the through hole, and the middle of the two auxiliary plates is on the same horizontal plane as the middle of the rotating roller and the extrusion roller.

[0026] As attached Figure 1-6The flexible circuit board processing material pulling mechanism shown includes a mounting base plate 1. A fixed upright plate 2 and two first support plates 3 are fixedly connected to the top of the mounting base plate 1. A through hole 4 is opened in the middle of the fixed upright plate 2. A rotating roller 7 and a pressing roller 8 are arranged between the two first support plates 3. Through the cooperation of the rotating roller 7 and the pressing roller 8, the processed flexible circuit board product can be pulled. The rotating roller 7 and the pressing roller 8 are supported by the first support plates 3. The through hole 4 facilitates the conveying. A support base 5 is fixedly connected to one side of one of the first support plates 3. A motor 6 is fixedly connected to one side of the support base 5.

[0027] The two sides of the extrusion roller 8 are symmetrically provided with second support plates 9. The two first support plates 3 are symmetrically fixedly connected to the opposite sides of the first electric push rod 10. The output end of the first electric push rod 10 is fitted with a nut 11. A slot 12 is opened at one end of the second support plate 9 corresponding to the nut 11. By starting the first electric push rod 10, the second support plate 9 is controlled to drive the extrusion roller 8 to move. The distance between the rotating roller 7 and the extrusion roller 8 can be adjusted, thereby adjusting the extrusion intensity on the finished flexible circuit board, which is convenient for material pulling. The movement distance of the second support plate 9 can be precisely controlled by the controller, which can also precisely control the movement distance of the extrusion roller 8, which is convenient for precise adjustment of the extrusion intensity. At the same time, the cooperation of the nut 11 and the slot 12 makes it easy to connect the second support plate 9 and the first electric push rod 10, which is convenient for assembly, disassembly and cleaning, and improves the use effect.

[0028] A baffle 14 is provided on the side of the fixed upright plate 2 away from the first support plate 3. The bottom ends of the baffle 14 are symmetrically provided with second electric push rods 15. A sensor 17 is fixedly connected to the side of the mounting base plate 1 at the position corresponding to the baffle 14. The second electric push rod 15 is activated to control the baffle 14 to move up and down, so that the baffle 14 corresponds to the through hole 4, which is convenient for sealing the through hole 4. The quality of the finished product passing through the middle of the through hole 4 can be detected by the sensor 17.

[0029] As attached Figure 1 , 2 As shown in Figures 4, 5, and 6, the first support plate 3 is located on the side of the fixed upright plate 2 away from the baffle 14. The output end of the motor 6 is fixedly connected to the rotating shaft of the rotating roller 7. The first support plate 3 supports and limits the rotating roller 7 and the extrusion roller 8. The rotating roller 7 is controlled to rotate by starting the motor 6, which is convenient for driving.

[0030] As attached Figure 1-6As shown, the extrusion roller 8 is rotatably connected to the second support plate 9 via a rotating shaft. The cross-sectional shape of the second support plate 9 is set to "L" shape. One end of the second support plate 9 is located on the top of the first support plate 3. By moving the second support plate 9 up and down, the extrusion roller 8 can be moved up and down, thereby adjusting the distance between the rotating roller 7 and the extrusion roller 8 for easy adjustment and use.

[0031] As attached Figure 2 , 3 As shown, the output end of the first electric push rod 10 passes through the middle of the slot 12. The nut 11 is located on the side of the second support plate 9 away from the first electric push rod 10 and the first support plate 3. The second support plate 9 is fixedly connected to the output end of the first electric push rod 10 by the nut 11. Starting the first electric push rod 10 can control the second support plate 9 to move horizontally, which is convenient for driving adjustment.

[0032] As attached Figure 2 , 6 As shown, two auxiliary plates 13 are fixedly connected to the middle of the through hole 4. The middle of the two auxiliary plates 13 is on the same horizontal plane as the middle of the rotating roller 7 and the extrusion roller 8. The auxiliary plates 13 guide and limit the conveyed finished products, thereby improving the conveying effect.

[0033] As attached Figure 1 , 2 As shown in Figures 4, 5, and 6, sliders 18 are fixedly connected to both ends of the baffle 14 near the fixed upright plate 2. Slide bars 19 are fixedly connected to one side of the fixed upright plate 2 at the position corresponding to the sliders 18. The sliders 18 and slide bars 19 are slidably connected. Through the cooperation of the sliders 18 and slide bars 19, the stability of the movement of the baffle 14 is improved.

[0034] As attached Figure 5 , 6 As shown, the second electric push rod 15 is fixed to one side of the mounting base plate 1, and the baffle 14 is fixedly connected to the side of the fixed upright plate 2 with a sealing gasket 16. Activating the second electric push rod 15 controls the movement of the baffle 14, which facilitates the sealing gasket 16 to seal the through hole 4, thereby improving the performance.

[0035] It is worth noting that a resistance detector is provided on one side of the first electric push rod 10 to detect the resistance of the first electric push rod 10 in controlling the movement of the second support plate 9. The resistance value detected can be used to determine the extrusion strength of the extrusion roller 8 and the rotating roller 7 on the raw material.

[0036] The working principle of this utility model is as follows: When in use, the mounting base plate 1 is fixed in the preset position, and the first electric push rod 10 is activated to control the second support plate 9 to drive the extrusion roller 8 to move away from the rotating roller 7, so that one end of the finished flexible circuit board can pass through the middle of the rotating roller 7 and the extrusion roller 8, and be transported to the other end through the middle of the through hole 4.

[0037] Then, the first electric push rod 10 is started to control the extrusion roller 8 to extrude the finished flexible circuit board. Then, the motor 6 is started to control the rotating roller 7 to rotate, thereby pulling the finished flexible circuit board and facilitating material feeding.

[0038] Rotating the nut 11 facilitates the separation of the second support plate 9 from the output end of the first electric push rod 10, making it convenient to disassemble, replace, or clean the extrusion roller 8, and to detect the conveyed finished product through the sensor 17;

[0039] By activating the second electric push rod 15, the baffle 14 is moved up and down, which facilitates the sealing of the gap between the two auxiliary plates 13 through the sealing gasket 16, thereby improving the performance.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
