[0044] Further, the outer wall of the operating table 1 is fixedly connected with a shell 51, and the shell 51 is provided with a slide groove 52. The shell 51 is penetrated by a rotating shaft 511 and is rotatably connected with the rotating shaft 511. The rotating shaft 511 is fixedly connected with the output end of the dual-axis motor 31. The rotating shaft 511 penetrates the impeller 1 56 and the impeller 3 58 and is rotatably connected with the impeller 1 56 and the impeller 3 58. The outer walls of the impeller 1 56 and the impeller 3 58 are provided with a notch, and the sliding sleeve 55 can be engaged with the impeller 1 56 and the impeller 3 58 through the cooperation between the notch and the elastic block 551. The rotating shaft 511 penetrates the sliding sleeve 55 and is slidably connected with the sliding sleeve 55. Both ends of the sliding sleeve 55 are slidably connected with elastic blocks 551, and the elastic block 551 is elastically connected to the inner wall of the sliding sleeve 55 through a spring. The sliding sleeve 55 penetrates the bearing 54 and is fixedly connected to the inner wall of the bearing 54. The outer wall of the bearing 54 is fixedly connected with a push block 53, and the push block 53 is slidably connected with the slide groove 52.

[0045] Furthermore, the shell 51 is penetrated by the tube body 1 571 and the air inlet pipe 581 and is fixedly connected to the tube body 1 571 and the air inlet pipe 581. The end of the tube body 1 571 away from the shell 51 penetrates the cylinder 57 and is fixedly connected to the cylinder 57. The side wall of the cylinder 57 is penetrated by the tube body 2 572 and is fixedly connected to the tube body 2 572. The end of the tube body 2 572 is fixedly connected to the hose 1 573. The end of the hose 1 573 is fixedly connected to the dust cover 574. The bottom end of the cylinder 57 is hinged with a cover 570. The cylinder 5 The outer wall of the bottom end is hinged with a locking block 575, and the inner wall of the cylinder 57 is fixedly connected with a filter 576 for filtering dust. The filter 576 is penetrated by a circular shaft 578 and is rotatably connected with the circular shaft 578. One end of the circular shaft 578 is fixedly connected with a scraper 577, which is driven to rotate by the rotation of the impeller 579 to clean the dust on the filter 576 and prevent the dust from accumulating on the outer wall of the filter 576. The other end of the circular shaft 578 is fixedly connected with the impeller 579.

[0046] Furthermore, one end of the air inlet pipe 581 away from the housing 51 is fixedly connected to a second hose 582, the end of the second hose 582 is fixedly connected to a hot air head 583, and the inner wall of the hot air head 583 is fixedly connected to a heating wire 584;

[0047] In the present invention, when in use, the mainboard is first placed on the outer wall of the placement table 2, and then the dual-axis motor 31 is started. At this time, the shaft body 311 fixedly connected to the output shaft of the dual-axis motor 31 rotates, such as Figure 6 As shown, at this time, the sliding block 312 is limited by the limit block 341. When the shaft body 311 rotates, the inclined surface of the inclined surface block 313 will squeeze the groove on the bidirectional screw rod 32, so that the bidirectional screw rod 32 rotates synchronously with the shaft body 311. At this time, the two groups of moving blocks 33 threadedly connected with the bidirectional screw rod 32 will move toward the center of the placement table 2. When the moving block 33 moves a certain distance, the pressure plate 331 will contact the main board, and the main board will apply a reaction force to the pressure plate 331, so that the pressure plate 331 and the U-shaped rod 332 slide. Figure 4When the U-shaped rod 332 moves, the U-shaped rod 332 will squeeze the round rod 334, causing the sliding rod 333 to move downward. In this process, the hinge rod 238 will apply a force to the long rod 34, causing the long rod 34 to slide on the placement table 2. When the pressure plate 331 coincides with the outer wall of the moving block 33, the limit block 341 just disengages from the sliding block 312, and the limit of the sliding block 312 is released. Therefore, when the inclined block 313 applies a force to the groove, the sliding block 312 will slide on the shaft body 311 under the action of the force, causing the inclined block 313 to disengage from the groove, thereby stopping the rotation of the bidirectional screw rod 32. Through this design, the main board can be protected to prevent it from being damaged by excessive clamping. At the same time, it can also automatically adapt to main boards of different sizes. At the same time, during the movement of the pressure plate 331 When the locking cam 335 is in the unlock state, the locking cam 336 is in the unlock state, and the locking cam 337 is in the unlock state, so that the locking cam 336 is unlocked and the locking cam 337 is unlocked, and the locking cam 337 is in the unlock state, so that the locking cam 336 is in the unlock state, and the locking cam 337 is in the unlock state, so that the locking cam 336 is in the unlock state, and the locking cam 337 is in the unlock state, so that the locking cam 336 is in the unlock state, and the locking cam 337 is in the unlock state, so that the locking cam 336 is in the unlock state, and the locking cam 337 is in the unlock state, so that the locking cam 336 is in the unlock state, and the locking cam 337 is in the unlock state, so that the locking cam 336 is in the unlock state, and the locking cam 337 is in the unlock state,

[0048] like Fig. 9As shown, when the dual-axis motor 31 is started, the rotating shaft 511 fixedly connected to the output end of the dual-axis motor 31 rotates synchronously, and then the pushing block 53 is pulled to the impeller 1 56. At this time, the bearing 54 fixedly connected to the pushing block 53 drives the sliding sleeve 55 to move toward the impeller 1 56 at the same time. In this process, the elastic block 551 will be squeezed by the outer wall of the impeller 1 56, so that the elastic block 551 completely enters the sliding sleeve 55. When the sliding sleeve 55 rotates, the elastic block 551 coincides with the notch on the impeller 1 56. At this time, the elastic block 551 will be elastically springing into the notch under the action of the elastic force of the spring, so that the impeller 1 56 is engaged with the sliding sleeve 55, so that the impeller 1 56 and the rotating shaft 511 rotate synchronously. When the impeller 1 56 rotates, the elastic block 551 and the notch on the impeller 1 56 are overlapped. At this time, the elastic block 551 will be elastically springing into the notch under the action of the elastic force of the spring, so that the impeller 1 56 is engaged with the sliding sleeve 55, so that the impeller 1 56 and the rotating shaft 511 rotate synchronously. When the dust collector 570 is in motion, negative pressure is generated inside the housing 51, so that suction is generated at the dust cover 574, so that the dust on the main board can be cleaned. At the same time, under the action of the suction, the second impeller 579 rotates synchronously. When the second impeller 579 rotates, the circular shaft 578 fixedly connected to the second impeller 579 drives the scraper 577 to rotate on the outer wall of the filter screen 576. Through the rotation of the scraper 577, the scraper 577 can clean the dust on the outer wall of the filter screen 576 to prevent dust from accumulating on the outer wall of the filter screen 576, thereby affecting the cleaning effect of the dust collection device. When the main board is cleaned, the limit of the cover body 570 can be released by rotating the locking block 575, so that the cover body 570 can be opened to clean the dust inside the cylinder 57.

[0049] When the pushing block 53 is pulled to the impeller three 58, the bearing 54 fixedly connected to the pushing block 53 drives the sliding sleeve 55 to move toward the impeller three 58 at the same time. During this process, the elastic block 551 will be squeezed by the outer wall of the impeller three 58, so that the elastic block 551 completely enters the sliding sleeve 55. When the sliding sleeve 55 rotates, the elastic block 551 coincides with the notch on the impeller three 58. At this time, the elastic block 551 will bounce into the notch under the elastic force of the spring, so that the impeller three 58 is engaged with the sliding sleeve 55, so that the impeller three 58 and the rotating shaft 511 rotate synchronously. At this time, the wind force generated by the impeller three 58 will be blown out through the hot air head 583, and at the same time, it will be blown out through the hot air head 583 after being heated by the heating wire 584, which can accurately act on the adhesive components on the mainboard to achieve convenient and efficient separation operation.
