[0001] This invention relates to the field of switch manufacturing technology, and more specifically, to a bonding device for an electrical switch. Background Technology

[0002] Electronic membrane switches are a new type of control system for electronic products that have become popular internationally in recent years. They combine decorative and functional features, integrating switch buttons, panel function text, and transparent windows, and have many advantages.

[0003] During the production of electronic membrane switches, circular spring contacts need to be attached to the sensor and fixed with adhesive. During the attachment process, because the spring contacts are flat, when the attachment device takes the spring contacts out of the storage box and moves them to the position corresponding to the sensor, the spring contacts may tilt, causing the center point of the spring contacts to deviate from the center point of the sensor, resulting in poor contact when the switch is in use. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a bonding device for an electric switch.

[0010] Furthermore, a slider is fixedly installed on the upper end of the moving rod, and the moving rod is slidably connected to the slide groove through the slider. A first bellows is fixedly installed on one end of the slider, and a first vent groove is opened inside the slider. One end of the first vent groove is connected to the inside of the piston groove, and the other end of the first vent groove is connected to the inside of the first bellows.

[0011] Furthermore, a compression spring is fitted around the outside of the first bellows, with one end of the compression spring fixedly connected to the slider and the other end of the compression spring fixedly connected to the inner wall of the groove.

[0012] Furthermore, two guide blocks are slidably installed inside the arc-shaped groove. The guide blocks are fixedly connected to the crossbar, and the crossbar is slidably connected to the arc-shaped groove through the guide blocks. A second corrugated pipe is installed inside the arc-shaped groove. A second ventilation groove is opened inside the guide blocks. One end of the second ventilation groove is connected to the inside of the first corrugated pipe, and the other end of the second ventilation groove is connected to the inside of the second corrugated pipe.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 7An adhesive device for an electric switch includes an adsorption cylinder 2 mounted on a robotic arm 1. The adsorption cylinder 2 has a through groove 201 inside, and a fan 202 is fixedly mounted on the upper side of the adsorption cylinder 2. The air intake of the fan 202 is connected to the inside of the through groove 201. The outer wall of the adsorption cylinder 2 has two arc-shaped grooves 203, and each arc-shaped groove 203 is equipped with two correction components 3 for correcting the position of the film. The correction assembly 3 includes a crossbar 301, a groove 302 is provided at the lower end of the crossbar 301, a moving rod 303 is slidably installed on the lower side of the groove 302, a piston groove 304 is provided inside the moving rod 303, and a correction rod 305 is slidably installed inside the piston groove 304. The lower end of the correction rod 305 extends through the inner wall of the piston groove 304 to the lower side of the moving rod 303. A first shrinkage groove 306 is provided at one end of the lower side of the correction rod 305. A support plate 307 is slidably installed inside the first shrinkage groove 306. A first return spring 308 is fixedly installed at one end of the support plate 307 inside the first shrinkage groove 306. The other end of the first return spring 308 is fixedly connected to the inner wall of the first shrinkage groove 306. Two guide blocks 204 are slidably installed inside the arc-shaped groove 203. The guide blocks 204 are fixedly connected to the crossbar 301. The crossbar 301 is slidably connected to the arc-shaped groove 203 through the guide blocks 204. A second corrugated pipe 205 is installed inside the arc-shaped groove 203. A second ventilation groove 206 is opened inside the guide blocks 204. One end of the second ventilation groove 206 is connected to the inside of the first corrugated pipe 313, and the other end of the second ventilation groove 206 is connected to the inside of the second corrugated pipe 205. A second return spring 207 is sleeved on the outside of the second corrugated pipe 205. One end of the second return spring 207 is fixedly connected to the guide blocks 204, and the other end of the second return spring 207 is fixedly connected to the inner wall of the arc-shaped groove 203. An air suction groove 208 is opened on the inner wall of the adsorption cylinder 2. One end of the air suction groove 208 is connected to the inside of the through groove 201, and the other end of the air suction groove 208 is connected to the inside of the second corrugated pipe 205.

[0021] By adopting the above technical solution, during use, the robotic arm 1 controls the movement of the adsorption cylinder 2, and then the fan 202 is started to draw in air. At this time, when the adsorption cylinder 2 is aligned with the spring sheet, the spring sheet can be adsorbed under the action of negative pressure, so that the spring sheet is located on the lower side of the through groove 201. After the spring sheet is adsorbed to the lower side of the adsorption cylinder 2, the spring sheet can seal the lower side of the through groove 201. Then, after the pressure in the through groove 201 decreases, the air inside the second corrugated pipe 205 can be drawn out through the air suction groove 208, so that the second corrugated pipe 205 will contract. After the second corrugated pipe 205 contracts, it can drive the fixed connection with it. When the guide block 204 moves, it can drive the crossbar 301 to move, so that the crossbar 301 can slide outside the adsorption cylinder 2 along the direction of the arc groove 203. When the crossbar 301 moves, it can drive the moving rod 303 to move along the direction of the arc groove 203. After moving, the moving rod 303 can slide outside the spring piece, thereby squeezing the outer wall of the spring piece. At this time, multiple moving rods 303 can move at the same time and push different positions of the outer wall of the spring piece, so that the spring piece moves on the lower side of the adsorption cylinder 2, thereby aligning the center of the spring piece with the center position of the through groove 201.

[0022] The lower end of the support plate 307 is provided with a pressure groove 309. The upper end of the inner wall of the pressure groove 309 is inclined. The lower end of the correction rod 305 is slidably installed with a top rod 310. The upper end of the top rod 310 is in pressure contact with the inclined part of the inner wall of the pressure groove 309. A compression spring 311 is provided inside the piston groove 304. The lower end of the compression spring 311 is fixedly connected to the upper end of the correction rod 305, and the upper end of the compression spring 311 is fixedly connected to the upper end of the inner wall of the piston groove 304. A slider 312 is fixedly installed on the upper end of the moving rod 303. The moving rod 303 is slidably connected to the slide groove 302 through the slider 312. A first bellows 313 is fixedly installed on one end of the slider 312. A first vent groove 314 is opened inside the slider 312. One end of the first vent groove 314 is connected to the inside of the piston groove 304, and the other end of the first vent groove 314 is connected to the inside of the first bellows 313. A compression spring 315 is sleeved on the outside of the first bellows 313. One end of the compression spring 315 is fixedly connected to the slider 312, and the other end of the compression spring 315 is fixedly connected to the inner wall of the slide groove 302.

[0023] By adopting the above technical solution, when the second bellows 205 contracts, the air in the first bellows 313 can enter the interior of the second bellows 205 through the second vent groove 206 and be drawn out by the fan 202 through the suction groove 208. At this time, the first bellows 313 will contract. After the first bellows 313 contracts, it can drive the slider 312 fixedly connected to it to move. When the slider 312 moves, it can only drive the moving rod 303 to move along the direction of the slide groove 302 due to the restriction of the slide groove 302. The contraction of the first bellows 313 can squeeze the compression spring 315, causing the compression spring 315 to contract. When the second bellows 205 contracts, it can squeeze the second return spring 207, causing the second return spring 207 to contract. When the first bellows 313 contracts, air in the piston groove 304 can enter the interior of the first bellows 313 through the first vent groove 314. Therefore, under the action of negative pressure, the correcting rod 305 can rise along the direction of the piston groove 304. After the correcting rod 305 rises, it can compress the compression spring 311, causing the compression spring 311 to deform. When the moving rod 303 moves along the direction of the slide groove 302, it can drive the correcting rod 305 to move, thereby causing the correcting rod 305 to move laterally and correct the airflow. After the rod 305 moves to the point where its outer wall is in contact with the outer wall of the spring, it will be blocked by the spring and will no longer move. This allows the outer wall of the correction rod 305 to be in contact with the outer wall of the spring. At the same time, since the multiple first bellows 313 are all connected to the inside of the air intake groove 208, the contraction amplitude of the multiple first bellows 313 is the same, so that the movement amplitude of the multiple moving rods 303 and the correction rod 305 is also the same. This allows the spring to be pushed to different positions at the same time, pushing the center position of the spring to be aligned with the center position of the through groove 201. When the correction rod 305 rises, it can drive the support plate 307 to rise. After the support plate 307 rises, it can squeeze the lower end of the spring sheet, so that the spring sheet remains horizontal, making it easy to align the spring sheet with the workpiece to be bonded, and avoiding the spring sheet from tilting and affecting the accuracy of bonding.

[0024] A second shrinkage groove 316 is provided at one end of the lower side of the correction rod 305. A squeezing rod 317 is slidably installed inside the second shrinkage groove 316. Both the second shrinkage groove 316 and the squeezing rod 317 are inclined. The second shrinkage groove 316 is located above the first shrinkage groove 306. A connecting groove 318 is provided at the lower side of the correction rod 305. One end of the connecting groove 318 is connected to the inside of the first shrinkage groove 306, and the other end of the connecting groove 318 is connected to the inside of the second shrinkage groove 316.

[0025] By adopting the above technical solution, when it is necessary to attach the spring sheet to a designated workpiece, the control robot arm 1 drives the suction cylinder 2 to descend. After the suction cylinder 2 descends, it can drive the crossbar 301 and the moving rod 303 and the correction rod 305 on the lower side of the crossbar 301 to descend through the guide block 204. After the correction rod 305 descends, it can drive the top rod 310 on its lower side to descend. After the top rod 310 descends, it can squeeze the inclined part of the inner wall of the pressure groove 309. At this time, under the action of the decomposed force of the extrusion force, the pallet 307 can move, thereby moving into the first shrinkage groove 306. When the pallet 307 moves into the first shrinkage groove 306, it can squeeze the first return spring 308, causing the first return spring 308 to contract. Furthermore, when the pallet 307 contracts into the first shrinkage groove 306, it can squeeze the first shrinkage spring 308. The air inside the groove 306 allows the air in the first shrinkage groove 306 to enter the second shrinkage groove 316 through the connecting groove 318. When the air enters the second shrinkage groove 316, it increases the pressure inside the second shrinkage groove 316, thereby pushing the extrusion rod 317 to move under the action of air pressure. After moving, the extrusion rod 317 can extend out of the second shrinkage groove 316. The extended extrusion rod 317 can squeeze the upper end of the spring sheet, thereby making the spring sheet fit with the workpiece to be bonded. This prevents the spring sheet from shifting position due to the flow characteristics of the accumulated adhesive when it is released. The pressed spring sheet can squeeze the adhesive, causing the adhesive to flow to both sides, reducing the gap between the spring sheet and the workpiece to be bonded, and reducing the error caused by the flow characteristics of the adhesive.

[0026] Usage: Control the robotic arm 1 to move the adsorption cylinder 2 and use the fan 202 to adsorb the spring sheet. Then, the position of the spring sheet is corrected by the correction component 3 so that the center of the spring sheet is aligned with the center of the through groove 201. Then, move the spring sheet to the workpiece to be bonded. Before bonding, apply adhesive for connection and fixation to the workpiece to be bonded. Then place the spring sheet on the workpiece to be bonded and press the spring sheet to reduce the gap between the spring sheet and the workpiece and reduce the error value. During the bonding process, the push rod 310 can squeeze the support plate 307 after contacting the workpiece to be bonded, so that the support plate 307 is separated from the lower end of the spring sheet, making it easier for the spring sheet to contact the workpiece to be bonded. After bonding is completed, turn off the fan 202. At this time, under the action of the first return spring 308, the second return spring 207, the compression spring 311, and the compression spring 315, each component can move to the initial position, which facilitates the use of the lower side.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
