Description

Technical Field

[0001] This utility model relates to the technical field of membrane keypad mounting, and in particular to a membrane keypad alignment component mounting device. Background Technology

[0002] Membrane keypad alignment and mounting refers to the process of accurately installing membrane keys with graphic or character markings onto designated locations (such as circuit boards, panels, and housings) during the manufacturing of electronic devices, instruments, and household appliances.

[0003] Because membrane buttons have adhesive backing, they need to be supported before installation. After alignment, the membrane button is pressed to partially adhere to the workpiece before the support component is removed. Existing technology, utility model patent CN222309876U discloses a membrane button alignment component installation device, including a worktable, support arms, slide rods, and alignment frames. Support arms are connected to both sides of the worktable, and slide rods are slidably connected to each support arm. Alignment frames are connected to the sides of the slide rods that are close to each other. This utility model uses the downward movement of the connecting frame to drive the contact strip downward. The downward movement of the contact strip compresses the wedge block, allowing the wedge block to control the slide rods to move away from each other as the connecting frame moves downward. This allows the membrane button support component to be automatically removed when the membrane button is pressed and pasted, improving the installation quality and efficiency of the membrane button.

[0004] The membrane button alignment component mounting device in the aforementioned patented technology has the following drawbacks in use: when positioning the workpiece, it can only be positioned by the positioning strip on the worktable. In actual use, the workpiece cannot be fixed. The workpiece cannot be effectively fixed, which will easily cause the workpiece to move when mounting the membrane button, affecting the mounting effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a membrane button alignment component mounting device that can position and fix the workpiece, effectively fix the workpiece, prevent the workpiece from moving when mounting the membrane button, and avoid affecting the mounting effect.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a membrane button alignment component mounting device, comprising a worktable, on the top of which a workpiece is placed, and a positioning clamping mechanism for positioning and fixing the workpiece. The positioning clamping mechanism includes an L-shaped positioning plate and a motor. The L-shaped positioning plate is fixedly connected to the left side of the top of the worktable, and the workpiece abuts against the inner side of the L-shaped positioning plate. The motor is fixedly installed at the right side of the front end of the worktable. A sliding groove is provided at the right side of the top of the worktable, and a bidirectional threaded rod is fixedly connected to the output end of the motor. The bidirectional threaded rod passes through the sliding groove and is rotatably mounted on the worktable. Two sets of L-shaped clamps and two sets of sliders are symmetrically threaded onto the bidirectional threaded rod. The two sets of L-shaped clamps and two sets of sliders are symmetrically slidably mounted in the sliding groove, and the sliders are located inside the L-shaped clamps. An L-shaped support is fixedly provided at the top of each set of sliders, and an electric telescopic rod is fixedly installed on each set of L-shaped supports. A pressure plate is fixedly provided at the output end of each set of electric telescopic rods.

[0008] Preferably, guide blocks are fixedly provided at both ends of the two sets of sliders, and the guide blocks are integrally formed with the sliders. Guide grooves are provided on both sides of the left and right ends of the slide groove. The two sets of sliders are symmetrically slidably installed in the slide groove through the cooperation of the guide blocks and the guide grooves.

[0009] Preferably, a support block is fixedly connected in the middle of the groove, and a bidirectional threaded rod is rotatably mounted on the support block.

[0010] Preferably, both sets of L-shaped clamps have grooves on their inner sides, and anti-slip pads are fixedly connected in the grooves, with the inner ends of the anti-slip pads aligned with the inner ends of the L-shaped clamps.

[0011] Preferably, a buffer pad is fixedly connected to the left end of both sets of pressure plates.

[0012] Preferably, the bidirectional threaded rod is made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the workpiece is placed on the workbench, with the left and rear ends of the workpiece abutting against the inner side of the L-shaped positioning plate for initial positioning. Then, the motor is started, causing the motor to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod drives two sets of L-shaped clamping plates and two sets of sliders to move inward along the slide groove until the L-shaped clamping plates clamp the front and rear ends of the workpiece. At this time, the slider drives the L-shaped support to move to the appropriate positions on both sides of the right end of the workpiece. By activating the electric telescopic rod, the electric telescopic rod pushes the pressure plate towards the workpiece, thereby pressing the pressure plate against the right end of the workpiece. Through the clamping of the front and rear sides of the workpiece by the L-shaped clamping plates and the clamping of the left and right sides of the workpiece by the pressure plate and the L-shaped positioning plate, the workpiece is fixed, thereby enabling the workpiece to be positioned and fixed, effectively fixing the workpiece and preventing it from moving when attaching the film button, thus avoiding affecting the attachment effect.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example 1

[0020] Please see Figures 1-4This utility model discloses a membrane keypad alignment component mounting device, comprising a worktable 1, an L-shaped positioning plate 3, and a motor 4. A workpiece 2 is placed on the top of the worktable 1. The L-shaped positioning plate 3 is fixedly connected to the left side of the top of the worktable 1, with the workpiece 2 resting against the inner side of the L-shaped positioning plate 3. The motor 4 is fixedly installed on the right side of the front end of the worktable 1. A slide groove 5 is provided on the right side of the top of the worktable 1. A bidirectional threaded rod 6 is fixedly connected to the output end of the motor 4. The bidirectional threaded rod 6 passes through the slide groove 5 and is rotatably mounted on the worktable 1. Two sets of L-shaped clamps 7 and two sets of sliders 8 are symmetrically screwed onto the bidirectional threaded rod 6. The two sets of L-shaped clamps 7 and two sets of sliders 8 are symmetrically slidably mounted in the slide groove 5, with the sliders 8 located inside the L-shaped clamps 7. L-shaped supports 9 are fixedly mounted on the top of each set of sliders 8. Electric telescopic rods 10 are fixedly mounted on each set of L-shaped supports 9. Pressure plates 11 are fixedly mounted on the output ends of each set of electric telescopic rods 10. The workpiece 2 is placed on the workbench 1, with its left and rear ends resting against the inner side of the L-shaped positioning plate 3 for initial positioning. Then, the motor 4 is started, causing the double-threaded rod 6 to rotate. The double-threaded rod 6 drives two sets of L-shaped clamping plates 7 and two sets of sliders 8 to move inward along the slide groove 5 until the L-shaped clamping plates 7 clamp the front and rear ends of the workpiece 2. At this time, the sliders 8 drive the L-shaped supports 9 to move to appropriate positions on both sides of the right end of the workpiece 2. By starting the electric telescopic rod 10, the electric telescopic rod 10 pushes the pressure plate 11 toward the workpiece 2, thereby pressing the pressure plate 11 against the right end of the workpiece 2. Through the clamping of the front and rear sides of the workpiece 2 by the L-shaped clamping plates 7 and the clamping of the left and right sides of the workpiece 2 by the pressure plate 11 and the L-shaped positioning plate 3, the workpiece 2 is fixed, thus enabling positioning and fixing of the workpiece. This effectively fixes the workpiece and prevents it from moving when attaching the film button, avoiding affecting the attachment effect. Example 2

[0021] Please see Figures 1-4This utility model discloses a membrane keypad alignment component mounting device, comprising a worktable 1, an L-shaped positioning plate 3, and a motor 4. A workpiece 2 is placed on the top of the worktable 1. The L-shaped positioning plate 3 is fixedly connected to the left side of the top of the worktable 1, with the workpiece 2 resting against the inner side of the L-shaped positioning plate 3. The motor 4 is fixedly installed on the right side of the front end of the worktable 1. A sliding groove 5 is provided on the right side of the top of the worktable 1. A bidirectional threaded rod 6 is fixedly connected to the output end of the motor 4. The bidirectional threaded rod 6 passes through the sliding groove 5 and is rotatably mounted on the worktable 1. The symmetrical screw-fitted sleeve 6 is equipped with two sets of L-shaped clamps 7 and two sets of sliders 8. The two sets of L-shaped clamps 7 are symmetrically slidably installed in the slide groove 5. Guide blocks 12 are fixed at both ends of the two sets of sliders 8. The guide blocks 12 are integrally formed with the sliders 8. Guide grooves 13 are opened on both sides of the left and right ends of the slide groove 5. The two sets of sliders 8 are symmetrically slidably installed in the slide groove 5 through the cooperation of the guide blocks 12 and the guide grooves 13. The sliders 8 are located inside the L-shaped clamps 7. L-shaped supports 9 are fixed at the top of the two sets of sliders 8. Both sets of electric telescopic rods 10 are fixedly installed on the worktable 1, and pressure plates 11 are fixedly installed at the output ends of both sets of electric telescopic rods 10. In use, the workpiece 2 is placed on the worktable 1, so that the left end and rear end of the workpiece 2 abut against the inner side of the L-shaped positioning plate 3 to initially position the workpiece 2. Then, the motor 4 is started, so that the motor 4 drives the bidirectional threaded rod 6 to rotate. The bidirectional threaded rod 6 drives the two sets of L-shaped clamping plates 7 and the two sets of sliders 8 to move inward along the slide groove 5 until the L-shaped clamping plates 7 clamp the front and rear ends of the workpiece 2. At this time, the sliders 8 drive the L-shaped clamping plates 7 to move inward along the slide groove 5. The support 9 is moved to a suitable position on both sides of the right end of the workpiece 2. By activating the electric telescopic rod 10, the electric telescopic rod 10 pushes the pressure plate 11 toward the workpiece 2, thereby pressing the pressure plate 11 against the right end of the workpiece 2. The workpiece 2 is fixed by the clamping of the front and rear sides of the workpiece 2 by the L-shaped clamping plate 7 and the clamping of the left and right sides of the workpiece 2 by the pressure plate 11 and the L-shaped positioning plate 3. This allows the workpiece to be positioned and fixed, effectively fixing the workpiece and preventing it from moving when attaching the film button, thus avoiding affecting the attachment effect.

[0022] Guide blocks 12 are fixedly provided at both ends of the two sets of sliders 8. The guide blocks 12 are integrally formed with the sliders 8. Guide grooves 13 are provided on both sides of the left and right ends of the slide groove 5. The two sets of sliders 8 are symmetrically slidably installed in the slide groove 5 through the cooperation of the guide blocks 12 and the guide grooves 13. When the bidirectional threaded rod 6 drives the sliders 8 to slide in the slide groove 5, the cooperation of the guide blocks 12 and the guide grooves 13 makes the slide groove 5 slide more stably, and at the same time activates the function of supporting the bidirectional threaded rod 6 to prevent the bidirectional threaded rod 6 from bending and sagging.

[0023] A support block 14 is fixedly connected in the middle of the slide groove 5, and the bidirectional threaded rod 6 is rotatably mounted on the support block 14. By setting the support block 14, the middle position of the bidirectional threaded rod 6 can be supported, further preventing the middle part of the bidirectional threaded rod 6 from sagging.

[0024] Both sets of L-shaped clamping plates 7 have grooves on their inner sides, and anti-slip pads 15 are fixedly connected in the grooves. The inner end of the anti-slip pads 15 is aligned with the inner end of the L-shaped clamping plates 7. By setting the anti-slip pads 15, the L-shaped clamping plates 7 can clamp the workpiece 2 more tightly and securely, avoiding slippage.

[0025] Both sets of pressure plates 11 are fixedly connected to the left end of a buffer pad 16. By setting the buffer pad 16, when the electric telescopic rod 10 pushes the pressure plate 11 to clamp the workpiece 2, it plays a buffering role and prevents the left end of the pressure plate 11 from directly contacting the right end of the workpiece 2.

[0026] The bidirectional threaded rod 6 is made of stainless steel; by using stainless steel, the surface of the bidirectional threaded rod 6 is less prone to rust.

[0027] This utility model discloses a membrane keypad alignment component mounting device. In operation, the workpiece 2 is placed on the worktable 1, with its left and rear ends abutting against the inner side of the L-shaped positioning plate 3 for initial positioning. Then, the motor 4 is started, driving the bidirectional threaded rod 6 to rotate. The bidirectional threaded rod 6 drives two sets of L-shaped clamping plates 7 and two sets of sliders 8 to move inward along the slide groove 5 until the L-shaped clamping plates 7 clamp the front and rear ends of the workpiece 2. At this point, the sliders 8 drive the L-shaped supports 9 to move to appropriate positions on both sides of the right end of the workpiece 2. Finally, by activating the electric telescopic rod 10, the electric telescopic rod 10 pushes the pressure plate 11 towards the workpiece 2. The worktable 11 is pressed against the right end of the workpiece 2 by the L-shaped clamping plate 7 clamping the front and rear sides of the workpiece 2, and the clamping plate 11 and L-shaped positioning plate 3 clamping the left and right sides of the workpiece 2, thus fixing the workpiece 2. After the workpiece 2 is fixed, the subsequent membrane button mounting operation is performed. In this utility model, both the worktable 1 and the workpiece 2 are referenced from a membrane button alignment part mounting device with patent publication number CN222309876U, which belongs to the disclosed prior art. The other specific structures and working principles of membrane button mounting have been described in detail in the published patent, so they will not be elaborated here.

[0028] The membrane button alignment component mounting device of this utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve the beneficial effect. The motor 4 and electric telescopic rod 10 of the membrane button alignment component mounting device of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
