Description

Technical Field

[0001] This invention belongs to the field of membrane switch processing technology, specifically relating to a flipping device for membrane switch processing. Background Technology

[0002] A membrane switch is an operating system that integrates button functions, indicator elements, and an instrument panel. It consists of four parts: a panel, an upper circuit, an isolation layer, and a lower circuit. During the manufacturing process of a membrane switch, drilling is required on one of its components, the circuit board. This drilling process generates a large amount of waste, but most existing drilling equipment does not have the function of cleaning up the waste on the circuit board.

[0003] For example, Chinese Patent Publication No. CN216015124U discloses a flipping fixture for membrane switch processing, which includes a base, a support leg fixedly connected to the lower end of the base, a housing fixedly connected to the upper end of the base, a drilling device provided on the top of the housing, a box fixedly connected to the upper end of the base, and a motor installed on the box, etc. This device uses two identical clamps designed, each clamp is provided with threaded rods, knobs, springs and other components to form a clamping structure for the circuit board, and uses the rotation of the rotating shaft to drive the clamps to rotate, thereby realizing the flipping of the circuit board, which facilitates double-sided drilling of the circuit board.

[0004] As described in the prior art of the aforementioned patent, although the circuit board can be clamped well, the debris generated during the drilling process tends to adhere to the circuit board and is not easy to fall off. The debris generated may affect the safety of subsequent production. Utility Model Content

[0005] The purpose of this invention is to provide a flipping device for membrane switch processing, which can easily blow off and clean debris adhering to the circuit board during drilling, thereby improving the cleanliness of the circuit board surface.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A flipping device for membrane switch processing includes a housing, clamping assemblies on the left and right sides of the housing, a drilling assembly at the top of the housing, air blowing assemblies on the front and rear sides of the drilling assembly, and a retrieval assembly at the bottom of the housing. The clamping assemblies include a clamping rod slidably connected to the housing, a clamping block mounted on the inner end of the clamping rod, and an outer end connected to a rotating shaft mounted on a connecting rod. The lower end of the connecting rod is connected to a connecting block. The air blowing assemblies include a sliding rod with both ends fixed to the inner wall of the housing, an adjusting block slidably disposed on the housing, and a nozzle mounted on the adjusting block.

[0008] In a preferred embodiment, the bottom of the outer casing is provided with a collection port for sucking away powder and debris.

[0009] In a preferred embodiment, the connecting blocks of the two sets of clamping assemblies are threadedly connected to a lead screw, the middle section of the lead screw is connected to a bearing seat, a driven gear is provided near the middle section of the lead screw, and a driving gear is meshed below the driven gear.

[0010] In a preferred embodiment, the drilling assembly includes a drill bit for drilling a circuit board. The drill bit is mounted on a drilling motor, which is connected to the lower end of a telescopic rod. A slider is mounted on the upper end of the telescopic rod, and the slider is slidably connected to a slide rod. Both ends of the slide rod are fixed to a connecting plate. A second slider is provided on the upper end of the connecting plate, and the second slider is slidably connected within a groove.

[0011] In a preferred embodiment, a telescopic rod three is connected to one side of the adjusting block, and the telescopic direction of the telescopic rod three is parallel to the sliding direction of the adjusting block on the slide rod two.

[0012] In a preferred embodiment, a collection box is connected below the recovery port, a discharge port is provided at the lower end of the collection box, a control valve is provided on the discharge port, a connecting pipe for connecting to a vacuum pump is installed on one side of the collection box, and a filter plate is provided inside the collection box facing the connecting pipe.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model places the circuit board inside the housing for drilling operations. The enclosed space created by the housing effectively prevents the spillage of debris and facilitates the collection of debris. In addition, the high-speed gas ejected by the nozzle in the air blowing assembly blows the debris adhering to the circuit board surface, achieving the purpose of cleaning the circuit board surface, avoiding the impact of debris on subsequent production operations, and improving product quality.

[0015] This utility model uses a recycling component connected to the lower end of the outer casing, and the collection box of the recycling component is connected to a vacuum pump through a connecting pipe. This creates a negative pressure inside the collection box, which allows the debris inside the outer casing to be sucked away, improving the cleaning ability of debris generated during drilling.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Please see the appendix Figure 1 and Figure 3 As shown, this utility model provides a flipping device for membrane switch processing, including a housing 1, clamping assemblies 2 respectively provided on the left and right sides of the housing 1, a drilling assembly 3 provided at the top of the inside of the housing 1, air blowing assemblies 4 respectively provided on the front and rear sides of the drilling assembly 3, and a recovery assembly 5 installed at the bottom of the housing 1; wherein, the clamping assembly 2 includes a clamping rod 21 slidably connected to the housing 1, a clamping block 20 installed on the inner end of the clamping rod 21, and the outer end of the clamping rod 21 connected to a rotating shaft 22, the rotating shaft 22 being installed on a connecting rod 23, and a connecting block 25 being connected to the lower end of the connecting rod 23; the air blowing assembly 4 includes a sliding rod 41 with both ends fixed to the inner wall of the housing 1, an adjusting block 42 slidably provided on the housing 1, and a nozzle 43 installed on the adjusting block 42;

[0028] When drilling a circuit board, the circuit board is placed between two sets of clamping components 2. The clamping rod 21 extends inward, causing the two clamping blocks 20 to come close to each other and clamp the circuit board. After clamping, the drilling component 3 is used to drill the circuit board. During drilling, debris will be generated and will adhere to the surface of the circuit board. In order to clean the debris from the surface of the circuit board, the nozzle 43 in the air blowing component 4 can be used to blow high-speed airflow onto the circuit board to blow away the dust on the surface of the circuit board, thereby achieving the purpose of cleaning the surface of the circuit board.

[0029] It is worth noting that a vacuum pump is connected to the outside of the nozzle 43 of the air blowing assembly 4. A solenoid valve is installed between the vacuum pump and the nozzle 43. The opening and closing of the solenoid valve are controlled by the control mechanism of the equipment. The solenoid valve is opened in a timely manner to blow away and clean the debris on the circuit board. In addition, when drilling the circuit board, in order to facilitate drilling on both sides of the circuit board, after drilling on one side, the clamping rod 21 can be driven by the servo motor 24 to rotate around the rotating shaft 22. The rotation of the clamping rod 21 drives the clamping block 20, thereby flipping the clamped circuit board so that the other side of the circuit board faces the drilling assembly 3 for drilling.

[0030] Please see Figure 1 and Figure 4As shown, the connecting block 25 in the two sets of clamping assemblies 2 is connected to the lead screw 26 by a thread. The middle section of the lead screw 26 is connected to the bearing seat 27. A driven gear 28 is provided near the middle section of the lead screw 26. A driving gear 29 is meshed below the driven gear 28.

[0031] To facilitate clamping or releasing the circuit board, the servo motor 291 drives the drive gear 29 to rotate. The drive gear 29 and the driven gear 28 are connected by tooth meshing, which in turn drives the driven gear 28 to rotate. The rotation of the driven gear 28 drives the lead screw 26 to rotate on the bearing seat 27. The rotation of the lead screw 26 and its threaded engagement with the connecting blocks 25 on both sides can move the connecting blocks 25 along the axis of the lead screw 26. The movement of the connecting blocks 25 drives the rotating shaft 22 connected to the connecting rod 23 to move. The movement of the rotating shaft 22 causes the clamping rod 21 to extend inward or outward. When the clamping rod 21 extends inward, it can move the clamping blocks 20 closer together, thus clamping the circuit board. When the clamping rod 21 extends outward, it can move the two clamping blocks 20 away from each other, thus releasing the circuit board and making it easy to remove the circuit board and replace it with a new one for continued drilling.

[0032] It is worth noting that the clamping rod 21 is slidably connected to the outer casing 1, and the lead screw 26 is only threaded at both ends, with a smooth structure in the middle, which facilitates rotational connection with the bearing seat 27.

[0033] The drilling assembly 3 includes a drill bit 31 for drilling the circuit board. The drill bit 31 is mounted on a drilling motor 32. The drilling motor 32 is connected to the lower end of the telescopic rod 33. A slider 34 is mounted on the upper end of the telescopic rod 33. The slider 34 is slidably connected to a slide rod 35. The two ends of the slide rod 35 are respectively fixed to a connecting plate 37. A slider 38 is provided on the upper end of the connecting plate 37. The slider 38 is slidably connected in a groove 39.

[0034] When drilling holes in a circuit board, the drilling motor 32 drives the drill bit 31 to rotate, and the extension of the telescopic rod 33 causes the drilling motor 32 and the drill bit 31 to fall and contact the circuit board for drilling. During drilling, depending on the drilling needs of different hole positions, the extension and retraction of the telescopic rod 36 can drive the slider 34 to move left and right on the slide rod 35, so that the position of the drill bit 31 can be adjusted left and right. The servo motor 392 drives the lead screw 391 to rotate in the slide groove 39, and the threaded connection between the lead screw 391 and the slider 38 causes the slider 38 to adjust its position back and forth in the slide groove 39. The slider 38 is fixedly connected to the slide rod 35 through the connecting plate 37, which can drive the drill bit 31 to adjust its position back and forth.

[0035] Please see Figure 3 As shown, a telescopic rod 44 is connected to one side of the adjusting block 42. The telescopic direction of the telescopic rod 44 is parallel to the sliding direction of the adjusting block 42 on the sliding rod 41.

[0036] In order to make the gas blown by the nozzle 43 blow to all parts of the circuit board surface, the extension and retraction of the telescopic rod 3 44 can drive the adjusting block 42 to move along the sliding rod 2 41, thereby driving the nozzle 43 on the adjusting block 42 to move left and right, so that the airflow blown from the nozzle 43 can blow to all parts of the circuit board and blow off the debris on the circuit board.

[0037] Please refer to Figure 5 As shown, the bottom of the outer casing 1 is provided with a collection port 11 for sucking away powder and debris. A collection box 51 is connected below the collection port 11. A discharge port 54 is provided at the lower end of the collection box 51. A control valve 55 is provided on the discharge port 54. A connecting pipe 52 for connecting to a vacuum pump is installed on one side of the collection box 51. A filter plate 53 is provided inside the collection box 51 facing the connecting pipe 52.

[0038] To collect debris inside the outer casing 1 and prevent leakage, the collection box 51 can be connected to a vacuum pump via a connecting pipe 52. A valve controlled by the equipment's control mechanism can be installed on the connecting pipe 52 to control the connection between the collection box 51 and the vacuum pump. When it is necessary to collect debris from the outer casing 1, the valve can be opened to create a vacuum in the collection box 51. The collection box 51 is connected to the outer casing 1 via the recovery port 11. The negative pressure generated in the collection box 51 draws the debris from the outer casing 1 into the collection box 51 for collection. When there is too much debris in the collection box 51, the control valve 55 on the discharge port 54 can be opened to discharge the debris from the discharge port 54 for unified processing. A filter plate 53 is installed at the connection between the collection box 51 and the connecting pipe 52 to prevent debris entering the collection box 51 from being sucked away, thus avoiding affecting the normal operation of the peripheral equipment.

[0039] Furthermore, an opening door can be provided at the front end of the outer casing 1, which can be opened to retrieve the circuit board and then closed during drilling operations to prevent debris from spilling out.

[0040] The working principle of this utility model is as follows: When drilling a circuit board, the circuit board is placed between two sets of clamping components 2. The clamping rod 21 extends inward, causing the two clamping blocks 20 to come close to each other and clamp the circuit board. After clamping, the drilling component 3 is used to drill the circuit board. During drilling, debris is generated and adheres to the surface of the circuit board. In order to clean the debris from the surface of the circuit board, the nozzle 43 in the air blowing component 4 can be used to blow high-speed airflow onto the circuit board to blow away the dust on the surface of the circuit board, thereby achieving the purpose of cleaning the surface of the circuit board.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
