The pressing plate 303 is installed on the second lifting plate 302 through the telescopic cylinder 425. The telescopic cylinder 425 can be locked on the first lifting plate 202 by an electric locking part (not shown in the figure) to prevent the turning plate 203 from rotating in a non-turning state.

Specifically:

[0039] The second power mechanism includes a rotating block 307 rotatably installed on one side of the first working station 101 through a rotating shaft 310 and an L-shaped block 305 hinged to the second lifting plate 302. A guide rod 306 is slidably arranged in the middle guide hole of the rotating block 307. One end of the guide rod 306 is hinged to the L-shaped block 305. A telescopic spring 308 sleeved outside the guide rod 306 is arranged between the L-shaped block 305 and the rotating block 307.

A transmission rod 210 is horizontally rotatably installed at the bottom end of the workbench 1.

The other end of the transmission rod 210 is connected to the rotating shaft 310 of the rotating block 307 through a pulley set 211.

[0041] To prevent the diaphragm from adhering to dust during the processing, an external air cylinder 403 is provided on the L-shaped block 305, and an internal air cylinder 404 capable of sliding along the inner side of the external air cylinder 403 is provided on the rotating block 307. A plug plate 405 is arranged inside the internal air cylinder 404. The plug plate 405 is fixedly connected to the external air cylinder 403 through a connecting rod 406 penetrating the inner wall of the internal air cylinder 404. A first air chamber 407 is formed between the outer end outer wall of the internal air cylinder 404 and the inner wall of the external air cylinder 403, and a second air chamber 408 is formed between the internal air cylinder 404 and the plug plate 405. The first air chamber 407 is connected to a first air inlet pipe 421 and a first air outlet pipe 423.

[0043] Among them, the adsorption mechanism 4 includes a plurality of suction cups 401 installed below the turning plate 203 and the pressing plate 303. The suction cups 401 are driven to suck air through an air extraction mechanism (not shown in the figure). When the air extraction mechanism works, it can evacuate the suction cups 401 to adsorb the diaphragm. Specifically:

[0044] A plurality of guiding and limiting grooves 415 are arranged in a circular array around the centers of the turning plate 203 and the pressing plate 303. A threaded rod 420 is rotatably arranged parallel to the guiding and limiting grooves 415. A sliding mounting block 402 whose position is limited to slide along the guiding and limiting grooves 415 is sleeved on the threaded rod 420 through a nut sleeve (not shown in the figure). The suction cups 401 are installed at the lower ends of the guiding and limiting grooves 415. The inner ends of a plurality of the threaded rods 420 are all provided with first wedge-shaped gears 417. Second wedge-shaped gears 418 that are meshed with the corresponding first wedge-shaped gears 417 on the corresponding plate are arranged at the centers of the turning plate 203 and the pressing plate 303. One threaded rod 420 installed on the turning plate 203 and the pressing plate 303 is respectively driven to rotate by a second motor 419.

[0045] The working principle of the device of the present invention:

[0046] First, adjust the position of the suction cups 401 according to the size of the diaphragm to be turned. Specifically:

[0047] Start the second motor 419. The second motor 419 drives a threaded rod 420 connected to its rotating shaft to rotate. The first wedge gear 417 installed inside the threaded rod 420 drives the second wedge gear 418 meshing with it to rotate. The second wedge gear 418 drives the remaining threaded rods 420 where the other first wedge gears 417 meshing with it are located to rotate. The sliding mounting block 402 sleeved on the threaded rod 420 by a nut sleeve moves towards the centers of the corresponding pressure plate 303 and the flipping plate 203 under the guiding action of the guiding and limiting groove 415, so that the suction cup 401 installed on the sliding mounting block 402 can adapt to the size of the diaphragm, enabling the device to be applicable to the flipping processing of diaphragms of different sizes.

[0048] In the initial state, the flipping plate 203 is located on the surface of the diaphragm loaded at the first station 101, and the suction cup 401 adsorbs the diaphragm on the lower surface of the flipping plate 203. At this time, the pressure plate 303 is located on the upper surface of the second station 102, and the suction of the diaphragm below the pressure plate 303 is released by the suction cup 401.

[0049] Next, start the first motor 204. The first motor 204 drives the lead screw 205 to rotate. The first lifting plate 202 sleeved by the lead screw nut set rises vertically along the lifting bracket 201, and the diaphragm adsorbed on the flipping plate 203 installed on the first lifting plate 202 is driven to rise.

[0050] When the driving gear 206 connected to the end of the flipping plate 203 meshes with the rack 207 during the rising process, the driving gear 206 will be driven by the rack 207 to rotate, and during the rotation, the flipping plate 203 is driven to rotate 180°, and the diaphragm adsorbed on the flipping plate 203 will also flip 180°.

[0051] During the above process, the pressure plate 303 has gone through two steps of rising vertically on the surface of the second station 102 and translating from above the second station 102 to above the first station 101. Specifically:

[0052] Step 1: In the initial state, the guide rod 306 is in a horizontal state, and the telescopic spring 308 between the rotating block 307 and the L-shaped block 305 is in a compressed state. Under the pressure of the telescopic spring 308, the sliding bracket 301 limited by the second lifting plate 302 connected to the L-shaped block 305 is abutted against the side wall of the vertical limiting plate 309, so that the second lifting plate 302 can only move along the vertical direction.

[0053] As the lead screw 205 rotates, the third wedge gear 208 sleeved on the lower end of the lead screw 205 drives the rotation of the transmission rod 210 where the fourth wedge gear 209 meshed with it is located, and drives the rotation of the rotating block 307 connected to the rotating shaft 310 through the pulley set 211. The guide rod 306 sleeved on the rotating block 307 rotates, and the second lifting plate 302 connected to the L-shaped block 305 connected to the outer end of the guide rod 306 rises vertically along the sliding bracket 301.

[0054] During this process, the distance between the L-shaped block 305 and the rotating block 307 increases, and the outer air cylinder 403 moves outward relative to the inner air cylinder 404. When the outer air cylinder 403 moves outward, the volume of the first air chamber 407 increases, and a negative pressure is formed inside it, causing the first suction assembly 409 to adsorb the dust on the surface of the first station 101. The dust formed on the front side of the diaphragm during the previous processing of the first station 101 can be adsorbed away, and it will not contaminate the diaphragm subsequently loaded onto the first station 101. The dust enters the first air chamber 407 along the first air inlet pipe 421; at the same time, the volume of the second air chamber 408 decreases, and the gas in the second air chamber 408 is squeezed, and the gas and the dust inside it are discharged through the second air outlet pipe 424.

[0055] Step 2: As the turning plate 203 above the first station 101 further rises and turns, during the rotation of the guide rod 306, the second lifting plate 302 will be limited by the top end of the horizontal guide rail 304, and the second lifting plate 302 will move along with the sliding bracket 301 from the second station 102 towards the first station 101.

[0056] During this process, the distance between the L-shaped block 305 and the rotating block 307 decreases, the telescopic spring 308 is compressed, and the outer air cylinder 403 moves inward relative to the inner air cylinder 404. When the outer air cylinder 403 moves inward, the volume of the first air chamber 407 decreases, and the gas inside it is squeezed. The gas and the dust in the first air chamber 407 are discharged along the first air outlet pipe 423; at the same time, the volume of the second air chamber 408 increases, and a negative pressure is formed in the second air chamber 408, causing the second suction assembly 410 on one side of the pressing plate 303 to adsorb the dust on the back of the diaphragm that flips with the turning plate 203 during the movement. The dust enters the second air chamber 408 along the second air inlet pipe 422.

[0057] When the pressing plate 303 moves above the second station 102, the suction cup 401 below the pressing plate 303 adsorbs the diaphragm that has flipped to the back with the turning plate 203. And drive the first motor 204 to rotate in the reverse direction, and the empty turning plate 203 resets to the surface of the first station 101, while the pressing plate 303 that adsorbs the flipped diaphragm will reset to the surface of the second station 102 and release the clamping of the diaphragm, and the processing of the back of the diaphragm is completed at the second station 102. And cycle the above steps.

[0058] Through the cooperation among the workbench 1, the lifting and flipping mechanism 2, the lifting and moving mechanism 3 and the adsorption mechanism 4, and through the cooperation between the flipping plate 203 and the pressing plate 303, on the one hand, the flipping processing of the diaphragm between the first station 101 and the second station 102 can be realized, improving the continuity of the double-sided processing of the diaphragm; on the other hand, during the operation of the device, the cleaning of the first station 101 of the feeding part and the back of the flipped diaphragm can also be realized, improving the flipping processing efficiency of the diaphragm.

[0059] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
