Description

Technical Field

[0001] This utility model belongs to the field of membrane switch processing technology, specifically relating to a membrane switch panel scratch repair and polishing equipment. Background Technology

[0002] Membrane switch panels, also known as tactile buttons, are electronic switches that integrate panel and switch functions. They typically consist of upper and lower circuitry, an insulating layer, and optional panel graphics printing. The substrate is often made of high-performance materials such as polycarbonate film or polyester film, which possess excellent light transmittance, wear resistance, heat resistance, and flame retardancy. During use, scratches inevitably appear on the surface of the membrane switch panel. To improve aesthetics, these scratches are repaired. Polishing is a common process to repair surface scratches. Polishing equipment effectively removes scratches, oxide layers, and other foreign matter from the surface of the membrane switch panel, restoring a smooth and flat surface. This is the basic function of polishing equipment in scratch repair. Polishing not only removes scratches but also makes the surface of the membrane switch panel brighter, enhancing its overall aesthetics and texture.

[0003] Currently, most existing membrane switch panel scratch repair and polishing equipment fixes the switch panel from both sides during the repair process. While this fixing method can ensure stability during the polishing process to a certain extent and allow the polishing work to proceed initially, factors such as vibration of the polishing equipment and uneven distribution of friction can still cause the fixed membrane switch panel to shift, affecting the precision and effect of the polishing. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for repairing scratches on a membrane switch panel. By setting a clamping part that slides synchronously inward or outward driven by a drive unit under the polishing table, the four sides of the switch panel can be fixed during the polishing process, thereby further improving stability.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A polishing and repair device for scratches on a membrane switch panel, comprising a polishing table,

[0007] It also includes a fixing mechanism, which includes a driving part and a clamping part, both of which are located below the polishing table; wherein the clamping part includes four sliders, which are arranged symmetrically in a cross shape on the polishing table, and the sliders are slidably connected to the inner wall of the polishing table for fastening the switch panel from four directions.

[0008] A fixed column and a support plate are provided, wherein the support plate is fixedly connected to the polishing table via the fixed column, and the driving part and the clamping part are disposed inside the support plate, wherein the driving part is slidably disposed on the upper surface of the support plate; for supporting the driving part and the clamping part;

[0009] A bracket and a polishing mechanism are provided, wherein the bracket is fixedly connected to the upper surface of the polishing table and the polishing mechanism is fixedly connected to the lower surface of the bracket, for polishing the switch panel.

[0010] In a preferred embodiment, the driving unit includes two cylinders, which are disposed on both sides of a fixed column. The cylinders are slidably disposed on the upper surface of a support plate. Fixed blocks are fixedly connected to both ends of each cylinder. A fixed shaft is fixedly connected between the two fixed blocks at each end. A triangular block is fixedly connected to the outer wall of the fixed shaft. The upper surface of the triangular block is fixedly connected to a slider. The extension and retraction movement of the cylinder can drive the corresponding slider to slide radially along the polishing table.

[0011] In a preferred embodiment, the clamping part further includes four L-plates, which are rotatably connected to the slider, and a rotating plate is rotatably connected to the other end of the L-plate, which is rotatably connected to the outer wall of the fixed column.

[0012] In a preferred embodiment, the fixed column is provided with an axial limiting structure to keep the axial position of the rotating plate stable during the sliding of the slider.

[0013] In a preferred embodiment, the slider is shaped like an I-beam, and the shape of the slider matches the thickness of the polishing table.

[0014] In a preferred embodiment, the polishing mechanism includes an adjustment section, with two adjustment sections arranged perpendicularly to each other.

[0030] like Figures 1 to 2 As shown, a membrane switch panel scratch repair and polishing device includes a polishing table 1 and a fixing mechanism. The fixing mechanism includes a driving part 2 and a clamping part 3, both of which are located below the polishing table 1. The clamping part 3 includes four sliders 301, which are arranged symmetrically in a cross shape on the polishing table 1. The sliders 301 are slidably connected to the inner wall of the polishing table 1 to fasten the switch panel from four directions.

[0031] The fixed column 4 and the support plate 5 are fixedly connected to the polishing table 1 through the fixed column 4. The driving part 2 and the clamping part 3 are disposed inside the support plate 5, wherein the driving part 2 is slidably disposed on the upper surface of the support plate 5; for supporting the driving part 2 and the clamping part 3.

[0032] The bracket 6 and the polishing mechanism 7 are fixedly connected to the upper surface of the polishing table 1 and the polishing mechanism 7 is fixedly connected to the lower surface of the bracket 6, and are used to polish the switch panel.

[0033] In the above embodiment, when it is necessary to use the device to polish and repair scratches on a membrane switch panel, the panel is first placed on the polishing table 1, and then the cylinder 201 is started. When the cylinder 201 is working, the slider 301 can be driven to slide on the polishing table 1 by the fixed block 202 set on the output end of the cylinder 201. The slider 301 is connected to the rotating plate 303 set in the center of the polishing table 1 through the L plate 302. The rotating plate 303 has a fixed post 4 fixed to the polishing table 1 in the middle. When the slider 301 slides inward or outward, the rotating plate 303 will be driven to rotate around the fixed post 4 through the L plate 302, which can drive the other three sliders 301 to slide inward or outward simultaneously. At the same time, a fixed block 202 is also connected to the tail end of the cylinder 201. The slider 301 slides, and the position of the rotating plate 303 remains unchanged when the slider 301 slides, thereby driving the cylinders 201 set on both sides of the fixed column 4 to retract and slide inward. When all four sliders 301 slide inward under the drive of the drive unit 2, the panel placed on the polishing table 1 can be fixed, thereby achieving the effect of fixing the panel and preventing the panel from shifting during the polishing process. After the panel is fixed, the polishing mechanism 7 above the polishing table 1 is started. The stepper motor 7011 drives the lead screw 7012 to rotate. When the lead screw 7012 rotates, the position of the fixed plate 702 can be adjusted, and the polishing head 703 can be adjusted to the appropriate polishing position. After polishing is completed, the cylinders 201 cause the four sliders 301 to slide outward, and the repaired panel can be removed.

[0034] The polishing table 1 has four grooves corresponding to the positions of the four sliders 301. The two sides of the sliders 301 are locked in the grooves, which can prevent the sliders 301 from falling off when they slide.

[0035] like Figure 3 - Figure 4 As shown, the drive unit 2 includes two cylinders 201, which are disposed on both sides of the fixed column 4. The cylinders 201 are slidably disposed on the upper surface of the support plate 5. Fixed blocks 202 are fixedly connected to both ends of the cylinders 201 respectively. A fixed shaft is fixedly connected between the two fixed blocks 202 at each end. A triangular block 203 is fixedly connected to the outer wall of the fixed shaft. The upper surface of the triangular block 203 is fixedly connected to the slider 301. The extension and retraction movement of the cylinders 201 can drive the corresponding slider 301 to slide radially along the polishing table 1.

[0036] In the above embodiment, when fixing the switch panel, the cylinder 201 is activated to drive the clamping part 3 to work. When the cylinder 201 is pushed, both ends of the two cylinders 201 are provided with fixing blocks 202. The two fixing blocks 202 at the tail end of the two cylinders 201 and the two fixing blocks 202 at the output end are respectively fixed by a fixing shaft. The two cylinders 201 are set to work synchronously. When the two cylinders 201 are working, the front and rear sliders 301 can be driven to slide on the polishing table 1 by the triangular block 203 on the fixing shaft. The setting of two cylinders 201 can also make the power more sufficient.

[0037] like Figure 3 - Figure 4 As shown, the clamping part 3 also includes four L-plates 302. The L-plates 302 are rotatably connected to the slider 301. The other end of the L-plates 302 is rotatably connected to a rotating plate 303. The rotating plate 303 is rotatably connected to the outer wall of the fixed column 4. The fixed column 4 is provided with an axial limiting structure to keep the axial position of the rotating plate 303 stable during the sliding of the slider 301.

[0038] In the above embodiment, when the drive unit 2 drives two of the sliders 301 to slide, the sliders 301 drive the rotating plate 303 to rotate through the corresponding L plate 302. Each L plate 302 and the rotating plate 303 form a four-bar linkage mechanism. By sliding any slider 301, the rotating plate 303 can be driven to rotate around the fixed column 4 and synchronously drive the remaining sliders 301 to make equidistant radial movements. In this way, the four sides of the switch panel placed in the middle can be fixed on the polishing table 1, so that the switch panel will not shift during the polishing process and its stability is improved.

[0039] like Figure 1 and Figure 4 As shown, the slider 301 is shaped like an I-beam, and the shape of the slider 301 matches the thickness of the polishing table 1.

[0040] In the above embodiment, the slider 301 is set in an I-shape so that the slider 301 can be locked on the polishing table 1. The two sides of the slider 301 can cover the upper and lower surfaces of the polishing table 1, so that the slider 301 is more stable when sliding and prevents the slider 301 from deviating in the vertical direction. The slider 301 can slide along the groove on the polishing table 1. The front end of the slider 301 is provided with an L-shaped locking plate, which can be locked on the upper surface of the switch panel to prevent the switch panel from deviating in the vertical direction during polishing.

[0041] like Figure 2 and Figure 5As shown, the polishing mechanism 7 includes an adjustment section 701. Two adjustment sections 701 are arranged perpendicularly to each other. Each adjustment section 701 includes a fixed box. A stepper motor 7011 is fixedly connected to one end of the fixed box. A lead screw 7012 is fixedly connected to the output end of the stepper motor 7011. The lead screw 7012 passes through the side wall of the fixed box and is rotatably connected to it. Two slide rails 7013 are symmetrically arranged on both sides of the lead screw 7012. Another set of adjustment sections 701 is threadedly connected to the outer wall of the lead screw 7012. A fixed plate 702 is provided on the side wall of the vertically arranged adjustment section 701. The fixed plate 702 is threadedly connected to the lead screw 7012. A polishing head 703 is fixedly connected to the lower surface of the fixed plate 702.

[0042] In the above embodiment, after the switch panel is fixed, the adjustment part 701 fixed to the bracket 6 is activated. The horizontal stepper motor 7011 drives the screw 7012 fixed to it to rotate. The screw 7012 can drive the vertical adjustment part 701 to move left and right, thereby driving the polishing head 703 to move left and right. At the same time, the vertical adjustment part 701 is activated to drive the fixing plate 702 to move up and down, thereby adjusting the height of the polishing head 703. The two adjustment parts 701 cooperate to adjust the three-dimensional position of the polishing head 703 to a suitable polishing position. After polishing, the polishing head 703 can be removed from the top of the repaired switch panel for easy access to the switch panel. During the polishing process, the two adjustment parts 701 can also cooperate to adjust the polishing process, making the polishing range more comprehensive.

[0043] The horizontal and vertical fixing boxes are equipped with slide rails 7013 to ensure the stability of the vertical adjustment part 701 and the stability of the movement of the fixing plate 702 and polishing head 703, respectively.

[0044] The working principle of this utility model is as follows: When the device is needed to polish and repair scratches on a membrane switch panel, the panel is first placed on the polishing table 1, and then the cylinder 201 is started. When the cylinder 201 is working, the slider 301 can be driven to slide on the polishing table 1 by the fixed block 202 set on the output end of the cylinder 201. The slider 301 is connected to the rotating plate 303 set in the center of the polishing table 1 through the L plate 302. The rotating plate 303 has a fixed post 4 fixed to the polishing table 1 in the middle. When the slider 301 slides inward or outward, the rotating plate 303 will be driven to rotate around the fixed post 4 through the L plate 302, which can drive the other three sliders 301 to slide inward or outward synchronously. At the same time, the tail end of the cylinder 201 is also connected to the fixed block 202. A slider 301 is used, and the position of the rotating plate 303 remains unchanged when the slider 301 slides, thereby driving the cylinders 201 set on both sides of the fixed column 4 to retract and slide inward. When all four sliders 301 slide inward under the drive of the drive unit 2, the panel placed on the polishing table 1 can be fixed, thereby fixing the panel and preventing the panel from shifting during the polishing process. After the panel is fixed, the polishing mechanism 7 above the polishing table 1 is started. The stepper motor 7011 drives the lead screw 7012 to rotate. When the lead screw 7012 rotates, the position of the fixed plate 702 can be adjusted, and the polishing head 703 can be adjusted to the appropriate polishing position. After polishing is completed, the cylinders 201 cause the four sliders 301 to slide outward, and the repaired panel can be removed.

[0045] 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 principle 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 field.
