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

[0007] A vacuum adsorption flipping stage for assembling a membrane switch includes:

[0008] A base, wherein a U-shaped mounting plate is fixedly installed on the top surface of the base;

[0009] An adsorption mechanism is disposed on the top of the base and is used to adsorb and fix the circuit board layer of the membrane switch.

[0010] A clamping mechanism is provided on the left and right sides inside the U-shaped mounting plate. The clamping mechanism is used to clamp and fix the panel layer of the membrane switch.

[0011] A flipping mechanism is provided on the side of the clamping mechanism and is used to flip the clamping mechanism and the panel layer.

[0012] In a preferred embodiment, a first cylinder is fixedly installed on the bottom surface inside the base, and an adsorption mechanism is provided above the first cylinder. The adsorption mechanism includes a vacuum pump, a vacuum tube, a placement stage, a vacuum chamber, and adsorption holes. A vacuum pump is fixedly installed on the top surface of the output end of the first cylinder. The output end of the vacuum pump is fixedly connected to a vacuum tube. The top surface of the vacuum tube is fixedly connected to a placement stage. A vacuum chamber is provided inside the placement stage, and multiple adsorption holes penetrating into the vacuum chamber are provided on the top surface of the placement stage.

[0013] In a preferred embodiment, the clamping mechanism includes a first rotating plate, a second rotating plate, a second cylinder, a clamping plate, and a rubber buffer pad.

A clamping plate is fixedly installed at the output end of the second cylinder. A rubber buffer pad is pasted on the side of the clamping plate away from the second cylinder.

[0014] In a preferred embodiment, the side of the first rotating plate is rotatably connected to the U-shaped mounting plate, and the side of the second rotating plate is rotatably connected to the U-shaped mounting plate via a bearing.

[0015] In a preferred embodiment, the flipping mechanism includes a rotating rod, a connecting plate, a movable plate, a handle, an insert rod, a limiting plate, a return spring, a slot, and a guide rod. The rotating rod is fixedly mounted on the side of the first rotating plate away from the second cylinder. The connecting plate is fixedly mounted on the other side of the rotating rod. The movable plate is mounted on the other side of the connecting plate. The handle is fixedly mounted on the other side of the movable plate. The insert rod, guide rod, and symmetrical return springs are fixedly mounted on the side of the movable plate near the connecting plate. The limiting plate extends through the outer side of the insert rod. The outer side of the U-shaped mounting plate has multiple slots arranged in a circular array to accommodate the insert rod. The insert rod is slidably connected to the U-shaped mounting plate through the slots.

[0016] In a preferred embodiment, the outer side of the U-shaped mounting plate has a through hole for a rotating rod, the rotating rod passes through the through hole and is rotatably connected to the U-shaped mounting plate, the side of the connecting plate is rotatably connected to the U-shaped mounting plate, the limiting plate is fixedly connected to the insert rod, the side of the connecting plate near the U-shaped mounting plate has a transverse groove for a limiting plate, the limiting plate is slidably connected to the connecting plate through the transverse groove, the side of the connecting plate has symmetrical mounting grooves, the end of the return spring away from the movable plate is fixedly connected to the inner wall of the mounting groove, the side of the connecting plate has a guide groove for a guide rod, the guide rod is slidably connected to the connecting plate through the guide groove.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention uses an adsorption mechanism to place the circuit board layer of the membrane switch in the center of the top surface of the placement platform. Running a vacuum pump creates a negative pressure inside the vacuum chamber, which can adsorb and fix the circuit board layer, making it convenient to assemble the circuit board layer.

[0019] This utility model, by setting a clamping mechanism, places the panel layer of the membrane switch between two clamping plates, aligns the panel layer with the circuit board layer, controls the second cylinder to drive the clamping plates to move closer to each other, which can clamp and fix the panel layer. The rubber buffer pad can play a buffering role before the clamping plates clamp the panel layer. Controlling the first cylinder to drive the circuit board layer to move upward can splice and assemble it with the panel layer.

[0020] This utility model, by setting a flipping mechanism, allows the panel layer to be flipped when needed. Pulling the handle outward causes the insertion rod to disengage from the slot, which releases the flipping mechanism from the panel layer. Rotating the handle causes the clamping mechanism and the panel layer to rotate, which can adjust the rotation angle of the panel layer. Releasing the handle allows the insertion rod to re-engage into the slot, which can re-limit the position of the panel layer. The operation is simple and quick, and it has strong applicability.

[0034] Please see the appendix Figure 1 As shown, this utility model provides a vacuum adsorption flipping table for assembling membrane switches, including: a base 100, an adsorption mechanism 400, a clamping mechanism 500, and a flipping mechanism 600.

[0035] In a preferred embodiment, please refer to Figures 1 to 2 A U-shaped mounting plate 200 is fixedly installed on the top surface of the base 100. A first cylinder 300 is fixedly installed on the bottom surface inside the base 100. An adsorption mechanism 400 is installed above the first cylinder 300. The adsorption mechanism 400 consists of a vacuum pump 401, a vacuum tube 402, a placement platform 403, a vacuum chamber 404, and adsorption holes 405. The vacuum pump 401 is fixedly installed on the top surface of the output end of the first cylinder 300. The vacuum pump 401 penetrates the base 100 to the outside of the base 100. The output end of the vacuum pump 401 is fixed and connected to the vacuum tube 402. The top surface of the vacuum tube 402 is fixed and connected to the placement platform 403. The vacuum chamber 404 is provided inside the placement platform 403. The vacuum tube 402 is connected to the vacuum chamber 404. Multiple adsorption holes 405 penetrating into the vacuum chamber 404 are provided on the top surface of the placement platform 403.

[0036] In this embodiment, the circuit board layer of the membrane switch is placed in the center of the top surface of the placement platform 403. The vacuum pump 401 is run to create a negative pressure inside the vacuum chamber 404, which can adsorb and fix the circuit board layer, making it convenient to assemble the circuit board layer.

[0037] In a preferred embodiment, please refer to Figures 1 to 4The U-shaped mounting plate 200 has clamping mechanisms 500 on its left and right sides. The clamping mechanisms 500 are composed of a first rotating plate 501, a second rotating plate 502, a second cylinder 503, a clamping plate 504, and a rubber buffer pad 505. The U-shaped mounting plate 200 has symmetrical first rotating plates 501 and second rotating plates 502 on its left and right sides. The second cylinder 503 is fixedly installed on the side of the first rotating plate 501 and the second rotating plate 502 that are close to each other. The clamping plate 504 is fixedly installed at the output end of the second cylinder 503. The rubber buffer pad 505 is attached to the side of the clamping plate 504 away from the second cylinder 503.

[0038] In this embodiment, the side of the first rotating plate 501 is rotatably connected to the U-shaped mounting plate 200, and the side of the second rotating plate 502 is rotatably connected to the U-shaped mounting plate 200 via a bearing.

[0039] In this embodiment, the panel layer of the membrane switch is placed between two clamping plates 504, and the panel layer is aligned with the circuit board layer. Controlling the second cylinder 503 to drive the clamping plates 504 to move closer to each other can clamp and fix the panel layer. The rubber buffer pad 505 can play a buffering role before the clamping plates 504 clamp the panel layer. Controlling the first cylinder 300 to drive the circuit board layer to move upward can splice and assemble it with the panel layer.

[0040] In a preferred embodiment, please refer to Figures 1 to 4 The clamping mechanism 500 has a flipping mechanism 600 on its side. The flipping mechanism 600 consists of a rotating rod 601, a connecting plate 602, a movable plate 603, a handle 604, an insert rod 605, a limiting plate 606, a return spring 607, a slot 608, and a guide rod 609. The rotating rod 601 is fixedly mounted on the side of the first rotating plate 501 away from the second cylinder 503. The connecting plate 602 is fixedly mounted on the other side of the rotating rod 601. The movable plate 603 is mounted on the other side of the connecting plate 602. The handle 604 is fixedly mounted on the other side of the movable plate 603. A rod 605, a guide rod 609, and symmetrical return springs 607 are fixedly installed on the side of plate 603 near the connecting plate 602. A limit plate 606 is provided through the outside of the rod 605. Multiple slots 608 that are adapted to the rod 605 are arranged in a circular array on the outside of the U-shaped mounting plate 200. The rod 605 is slidably connected to the U-shaped mounting plate 200 through the slots 608. When the rod 605 is engaged in the slot 608, the connecting plate 602 is difficult to move relative to the U-shaped mounting plate 200, thereby preventing the clamping mechanism 500 and the panel layer from continuing to rotate.

[0041] In this embodiment, a through hole for a rotating rod 601 is provided on the outer side of the U-shaped mounting plate 200. The rotating rod 601 passes through the through hole and is rotatably connected to the U-shaped mounting plate 200. The side of the connecting plate 602 is rotatably connected to the U-shaped mounting plate 200. The limiting plate 606 is fixedly connected to the insertion rod 605. A transverse groove for a limiting plate 606 is provided on the side of the connecting plate 602 near the U-shaped mounting plate 200. The limiting plate 606 is slidably connected to the connecting plate 602 through the transverse groove. A symmetrical mounting groove is provided on the side of the connecting plate 602. A return spring 607 is provided inside the mounting groove. The end of the return spring 607 away from the movable plate 603 is fixedly connected to the inner wall of the mounting groove. The return spring 607 pulls the movable plate 603 to make the insertion rod 605 engage inside the slot 608. A guide groove for a guide rod 609 is provided on the side of the connecting plate 602. The guide rod 609 is slidably connected to the connecting plate 602 through the guide groove.

[0042] In this embodiment, when the panel layer needs to be flipped, pulling the handle 604 outward causes the movable plate 603, the insertion rod 605, and the limiting plate 606 to move. The return spring 607 is extended, and the insertion rod 605 moves outward from the slot 608 until the insertion rod 605 disengages from the slot 608, thus releasing the flipping mechanism 600 from limiting the panel layer. Rotating the handle 604 causes the movable plate 603, the insertion rod 605, the limiting plate 606, and the guide rod 609 to rotate, thereby causing the connecting plate 602 to rotate. The rotation of the connecting plate 602 causes the rotating rod 601 to rotate, and the rotation of the rotating rod 601 causes... The clamping mechanism 500 and the panel layer rotate, which can adjust the rotation angle of the panel layer. The outer side of the U-shaped mounting plate 200 is provided with scale lines that correspond one-to-one with the slot 608. When the flipping mechanism 600 completes the angle adjustment of the panel layer, the insertion rod 605 is aligned with the slot 608. The handle 604 is released, which causes the reset spring 607 to pull the movable plate 603 back to its original position, thereby allowing the insertion rod 605 to be re-engaged into the slot 608, and the position of the panel layer is re-limited. The operation is simple and quick, and it has strong applicability. The guide rod 609 never leaves the guide groove during the movement.

[0043] The working principle of this utility model is as follows:

[0044] In use, the circuit board layer of the membrane switch is placed in the center of the top surface of the placement platform 403. The vacuum pump 401 is run to create a negative pressure inside the vacuum chamber 404, which adsorbs and fixes the circuit board layer. The panel layer of the membrane switch is placed between two clamping plates 504, aligning the panel layer with the circuit board layer. The second cylinder 503 is controlled to move the clamping plates 504 closer together, clamping and fixing the panel layer. When the panel layer needs to be flipped, the handle 604 is pulled outwards, moving the movable plate 603, the insertion rod 605, and the limiting plate 606. The return spring 607 is extended, and the insertion rod 605 moves outwards from the slot 608 until it disengages from the slot 608, releasing the limiting effect of the flipping mechanism 600 on the panel layer. Rotating the handle 604 causes the movable plate 603, the insertion rod 605, the limiting plate 606, and the guide rod 609 to rotate, thereby causing the connecting plate 602 to rotate. The rotation of the connecting plate 602 causes the rotating rod 601 to rotate, and the rotation of the rotating rod 601 causes the clamping mechanism 500 and the panel layer to rotate. The rotation angle of the panel layer can be adjusted. When the flipping mechanism 600 completes the angle adjustment of the panel layer, the insertion rod 605 is aligned with the slot 608. Releasing the handle 604 causes the reset spring 607 to pull the movable plate 603 back to its original position, thereby causing the insertion rod 605 to re-engage inside the slot 608, and the position of the panel layer is re-limited. Controlling the first cylinder 300 to drive the circuit board layer to move upward can be spliced ​​and assembled with the panel layer.

[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 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.
