Description

Technical Field

[0001] The utility model relates to the technical field of FPC board processing, in particular to a double-row double-sided high-efficiency feeding and film tearing device. Background Art

[0002] FPC board (flexible printed circuit board) is a printed circuit made of flexible insulating substrate. With its unique flexibility and high reliability, it has become an indispensable electrical connection solution in modern electronic devices. It has excellent electrical properties and can be bent and wound freely, meeting the requirements of electronic products for miniaturization and mobility. FPC boards are widely used in mobile devices, automotive electronics, medical equipment and other fields to achieve lightweight and highly integrated designs. Its manufacturing process includes multiple strictly controlled steps to ensure product quality and reliability.

[0003] At present, in the production process of FPC boards, in order to protect the surface circuit and copper foil from damage or pollution, a protective film, also called cover film or encapsulation, will be covered, which mainly plays the role of solder resistance and protection. When the FPC board is completed and ready for the next assembly or use, this protective film needs to be torn off to expose the copper foil and circuit pattern, so that the FPC board can be effectively electrically connected with other electronic components or devices.

[0004] The existing FPC board tearing efficiency on the market is low. The main reason for the low efficiency is that it only adopts a single-row tearing structure, and the loading operation is cumbersome and inconvenient, which greatly limits the efficiency of FPC board production. Utility Model Content

[0005] The utility model aims to provide a double-row double-sided efficient feeding and film tearing device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A double-row, double-sided, high-efficiency loading and film tearing equipment, comprising a box body, a plurality of supporting bases are arranged under the box body, a plurality of universal wheels are fixedly connected to the bottom of the box body, and a control panel is fixedly connected to the outside of the box body; the characteristics are: a plurality of fans are fixedly connected to the bottom of the rear side of the box body, a blower is fixedly connected inside the box body, a conveying roller is arranged above the blower, a plurality of waste film conveying belts are arranged in the box body, a collecting box is arranged below the waste film conveying belts, a first linear motor, a second linear motor and a third linear motor are respectively fixedly connected in the box body, a loading component for loading is arranged on one side of the box body, and a first film tearing component and a second film tearing component for tearing film are respectively arranged inside the box body.

[0008] When it is necessary to tear the film of the FPC board, the FPC boards with the film are stacked together and placed on the feeding component, and then the feeding component is operated by controlling the control panel to transfer the FPC board to the first film tearing component, and then the first film tearing component is operated to tear off the film on the surface of the FPC board, and then the second film tearing component is operated to tear off the film adhered to the other side of the FPC board. At this time, the second film tearing component will place the FPC board with the film torn off on the conveying roller, and at this time, the motor on one side of the conveying roller is controlled by the control panel to drive the conveying roller to rotate, so that the FPC board is collected. In this way, the film on both sides of two FPC boards can be torn off at the same time, thereby improving the efficiency of FPC board production.

[0009] A further improvement of the technical solution of the utility model is that: the loading component includes a first loading component and a second loading component, the first loading component includes a box body, a plurality of supporting bases and universal wheels are fixedly connected to the bottom of the box body, a plurality of electric push rods are fixedly connected to the inside of the box body, and the output ends of the electric push rods are fixedly connected to a placement plate; the second loading component includes a mobile linear motor, the mobile linear motor is fixedly connected to the box body, the output end of the mobile linear motor is connected to a servo module, and the output end of the servo module is connected to the mobile component.

[0010] The above technical solution is adopted. In this solution, when the film needs to be torn off, the FPC board is placed on the placement plate, and then the electric push rod is controlled by the control panel to work, so that the electric push rod is used in conjunction with the moving component to transfer the FPC board to the suction plate. The moving component includes a base plate, which is fixedly connected to the output end of the servo module. A plurality of adsorption rods are arranged on the base plate, and an electromagnetic valve is arranged on the back of the base plate. One end of the electromagnetic valve is connected to the adsorption rod, and the other end of the electromagnetic valve is connected to an external air pump. When one end of the adsorption rod contacts the FPC board, the air pump starts to work, and the air in the adsorption rod is evacuated to a negative pressure state through the electromagnetic valve. The FPC board will adhere firmly to the adsorption rod, and then the FPC board will be shifted by moving the linear motor.

[0011] A further improvement of the technical solution of the utility model is that the first film tearing component includes an adsorption component, which is connected to the output end of the first linear motor, and a film tearing device is arranged above the adsorption component, which is connected to the output end of the second linear motor.

[0012] The above technical solution is adopted. In this solution, when the feeding component sends the FPC board to the suction plate, the adsorption component will firmly adsorb the FPC board. At this time, the first linear motor works, and the film tearing device (the patent cited by the patent announcement number "CN218430390U") located above the adsorption component will peel off the film above the FPC board, and the torn film will fall onto the waste film conveying belt. At this time, the movement of the belt will drive the film to move until it falls into the collection box. The linear motor can directly convert electrical energy into mechanical energy of linear motion, which not only reduces energy loss and failure points, but also has the characteristics of high speed and high precision, thereby improving the efficiency of film tearing.

[0013] A further improvement of the technical solution of the utility model is that the second film tearing component includes an adsorption component, the adsorption component is connected to the output end of the third linear motor, a film tearing device is arranged below the adsorption component, and the film tearing device is connected to the other output end of the first linear motor.

[0014] The above-mentioned technical scheme is adopted. In this scheme, when one layer of the film on the FPC board is peeled off, the adsorption component in the first film-tearing component has no suction. At this time, the second film-tearing component will firmly adsorb the side of the FPC board without the film through the adsorption component, and then move the third linear motor through the film-tearing device to tear the film on the other side of the FPC board. At this time, the films on both sides of the FPC board are completely torn off. At this time, the second film-tearing component will drop the FPC board onto the conveying roller, thereby achieving the purpose of double-sided film tearing.

[0015] A further improvement of the technical solution of the utility model is that the adsorption component comprises a suction plate, a suction hole is provided on the suction plate, a vacuum generator is fixedly connected to one end of the suction plate, and the suction hole is communicated with the vacuum generator.

[0016] The above technical solution is adopted. In this solution, when the suction plate contacts the FPC board, the control panel controls the vacuum generator to start working to extract the air in the suction hole, and the FPC board is firmly sucked by negative pressure.

[0017] A further improvement of the technical solution of the utility model is that the box body and the cabinet body are connected by bolts.

[0018] By adopting the above technical solution, the position of the loading component can be changed as needed by arranging the box body and the box body to be connected by bolts, thereby expanding the applicability of the device.

[0019] A further improvement of the technical solution of the utility model is that a plurality of nozzles are installed on one side of the waste film conveying belt, and the nozzles are connected to the blower through an air flow regulator.

[0020] The above-mentioned technical solution is adopted, in which a nozzle is arranged on one side of the waste film conveyor belt to spray gas to the waste film conveyor belt, so that the torn film cannot adhere to the waste film conveyor belt, thereby preventing the torn film from interfering with the normal operation of the waste film conveyor belt.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a double-row double-sided efficient loading and film-tearing device. When the film of the FPC board needs to be torn, the FPC boards with the film are stacked together and placed on the loading component. Then, the loading component is operated by controlling the control panel to transfer the FPC board to the first film-tearing component. Then, the first film-tearing component is operated to tear off the film on the surface of the FPC board. Then, the second film-tearing component is operated to tear off the film adhered to the other side of the FPC board. At this time, the second film-tearing component will place the torn FPC board on the conveying roller. At this time, the motor on one side of the conveying roller is controlled by the control panel, so that the motor drives the conveying roller to rotate, so that the FPC board is collected. In this way, the film on both sides of two FPC boards can be torn off at the same time, thereby improving the efficiency of FPC board production.

[0038] In this embodiment, when it is necessary to tear the film of the FPC board, the FPC boards with the film are stacked together and placed on the loading component, and then the loading component is operated by controlling the control panel 2 to transfer the FPC board to the first film tearing component, and then the first film tearing component is operated to tear off the film on the surface of the FPC board, and then the second film tearing component is operated to tear off the film adhered to the other side of the FPC board. At this time, the second film tearing component will place the FPC board with the film torn off on the conveying roller 5, and at this time, the motor on one side of the conveying roller 5 is controlled by the control panel 2, so that the motor drives the conveying roller 5 to rotate, so that the FPC board is collected.

The FPC board will adhere firmly to the adsorption rod 25, and then the FPC board is displaced by moving the linear motor 14.

The film tearing device 17 (the patent cited is "CN218430390U") located above the adsorption component will peel off the film above the FPC board, and the torn film will fall onto the waste film conveying belt 6. At this time, the movement of the belt will drive the film to move until it falls into the collection box 7.

[0049] like Figure 3 As shown, preferably, a plurality of nozzles 22 are installed on one side of the waste film conveyor belt 6 , and the nozzles 22 are connected to the blower 4 via an air flow regulator 23 .

[0050] By arranging a nozzle 22 on one side of the waste film conveyor belt 6, gas can be sprayed to the waste film conveyor belt 6, so that the torn film cannot adhere to the waste film conveyor belt 6, thereby preventing the torn film from interfering with the normal operation of the waste film conveyor belt 6.

[0051] The following is a detailed description of the working principle of the double-row, double-sided, high-efficiency feeding and film tearing equipment.

[0052] like Figure 1-8As shown, when it is necessary to tear the film of the FPC board, the FPC boards with the film are stacked together and placed on the loading component, and then the loading component is operated by controlling the control panel 2 to transfer the FPC board to the first film-tearing component, and then the first film-tearing component is operated to tear off the film on the surface of the FPC board, and then the second film-tearing component is operated to tear off the film adhered to the other side of the FPC board. At this time, the second film-tearing component will place the FPC board with the film torn off on the conveying roller 5, and at this time, the motor on one side of the conveying roller 5 is controlled by the control panel 2, so that the motor drives the conveying roller 5 to rotate, so that the FPC board is collected. In this way, the film on both sides of the two FPC boards can be torn off at the same time, thereby improving the efficiency of FPC board production. When the film needs to be torn off, the FPC board is placed on the placement plate 13, and then the control panel 2 is used to control the electric push rod 12 to work, so that the electric push rod 12 is used in conjunction with the moving component to transfer the FPC board to the suction plate 18. The moving component includes a base plate 26, and the base plate 26 is fixedly connected to the output end of the servo module 16. A plurality of adsorption rods 25 are arranged on the base plate 26, and a solenoid valve 24 is arranged on the back of the base plate 26. One end of the solenoid valve 24 is connected to the adsorption rod 25, and the other end of the solenoid valve 24 is connected to an external air pump. When one end of the adsorption rod 25 contacts the FPC board, the air pump starts to work, and the air in the adsorption rod 25 is evacuated to a negative pressure state through the solenoid valve 24. The FPC board will adhere firmly to the adsorption rod 25, and then the FPC board is displaced by moving the linear motor 14. When the feeding component sends the FPC board to the suction plate 18, the adsorption component firmly adsorbs the FPC board, and the first linear motor 8 works. The film tearing device 17 (the patent cited by the patent announcement number "CN218430390U") located above the adsorption component will peel off the film above the FPC board, and the torn film will fall onto the waste film conveying belt 6. At this time, the movement of the belt will drive the film to move until it falls into the collection box 7. The linear motor can directly convert electrical energy into mechanical energy of linear motion, which not only reduces energy loss and failure points, but also has the characteristics of high speed and high precision, thereby improving the efficiency of film tearing. When one layer of the film on the FPC board is peeled off, the adsorption component in the first film-tearing component has no suction force. At this time, the second film-tearing component will firmly adsorb the side of the FPC board without the film through the adsorption component, and then the third linear motor 10 will work and move through the film-tearing device 17 to tear the film on the other side of the FPC board. At this time, the films on both sides of the FPC board are completely torn off. At this time, the second film-tearing component will drop the FPC board on the conveying roller 5, thereby achieving the purpose of double-sided film tearing. When the suction plate 18 contacts the FPC board, the control panel 2 controls the vacuum generator 20 to start working to extract the air in the suction hole 19, and use the negative pressure to firmly suck the FPC board. By setting the box body 11 and the box body 1 to be connected by bolts 21, the position of the loading component can be changed as needed, so that the applicability of the device is expanded.By arranging a nozzle 22 on one side of the waste film conveyor belt 6, gas can be sprayed to the waste film conveyor belt 6, so that the torn film cannot adhere to the waste film conveyor belt 6, thereby preventing the torn film from interfering with the normal operation of the waste film conveyor belt 6.

[0053] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
