The working process of the automatic assembly system for automobile control valve seals and screws in the embodiment is as follows: First, as shown in Figure 6, place the control valve 8 to be assembled at the positioning pin of the product positioning base 108, and pass through the first position After the sensor senses that the product is in place, it transmits the signal to the control module, which controls the stop cylinder 101, the base support lifting cylinder 103 and the clamping cylinder 110 to automatically lock the product; after the control button is activated, the seal conveyor guide 4 The vibration plate 402 and the feeding track 403 start working to transport the sealing gasket. When the first sealing gasket enters the gasket guide block 404, the third position sensor on the gasket guide block 404 senses that the first gasket is in place and sends the signal Passed to the control module, the seal lifting cylinder 405 is controlled to lift the seal, and the seal adsorption cylinder is controlled to drive the seal suction head 407 downward to absorb the first seal on the seal guide block 404. The sealing pad suction head 407 is a vacuum suction head. When the fourth position sensor located in the pipeline of the sealing pad suction head 407 senses that the sealing pad is adsorbed in place, the signal is transmitted to the control module, and the control module controls the rotation cylinder 413 to work. The rotating bracket 408 rotates to the position of the product positioning base 108, and its sealing pad suction head 407 is facing the sealing gasket assembly groove on the control valve 8 to be assembled. The sealing pad suction head 407 is controlled to deflate, and the sealing pad is placed on the control valve 8 to be assembled. The sealing gasket is installed in the groove; after the sealing gasket is assembled in place, the telescopic rotating cylinder 107 drives the product positioning base 108 to extend to the screw installation position directly below the screw suction locking mechanism 5.

There is an optical fiber sensor on the telescopic rotary cylinder 107, which can automatically detect that the telescopic rotary cylinder 107 is telescopically in place. When the product positioning base 108 moves in place, the screw feeding tray 301 and the screw guide rail 302 of the screw conveying guide device 3 can be controlled to transport the screws. Screw 11, the screw moves to the right from the automatic screw feeding tray 301 according to a specific state. The automatic screw feeding controller accepts the opening signal from the programmable controller and the mold suppression module. After the screw moves to the right and reaches the screw direct vibration mechanism, it continues to be fed in sequence. The screw blanking reversing mechanism 309 is reached. After reaching the position, the optical fiber sensor sends a signal to the programmable controller and the mold suppression module. The screw blanking reversing mechanism receives the sorting signals of the programmable controller and the mold suppressing module. The screw enters the screw blanking reversing mechanism 309. The screw-connecting magnetic isolation device in the material reversing mechanism 309 is then controlled by the programmable controller and the mold suppression module according to the program logic to push the screws to the screw-connecting magnetic isolation sleeve 306 by the telescopic cylinder 308, and then driven by the feeding cylinder 307. Screw to the screw installation position directly below the screw suction locking mechanism 5.

The control module controls the second lifting cylinder 511 to work and drive the screw suction sleeve 502 and screw suction head 503 to move down to suck the screw material receiving space. The magnetic sleeve 306 installs the screw, and after sucking the screw, the feeding cylinder 307 drives the screw receiving magnetic isolation sleeve 306 to return; the fifth position sensor on the second lifting cylinder 511 senses that the screw is sucked in place and the cylinder returns, and then the signal is transmitted To the control module, the control module controls the operation of the first lifting cylinder 508. The first lifting cylinder 508 drives the two support plates to move linearly downward along the support axis, and places the screws sucked by the screw suction head 503 on the product positioning base 108. In the screw assembly groove of the control valve 8 to be assembled, the rotating motor 501 drives the rotating rod and the screw suction head 503 to rotate at the same time, fixing and tightening the screws, and then controls the various components of the screw suction locking mechanism 5 to return to their positions, completing the drive of the control valve to be assembled. 8 Front gasket and screw assembly work.

After the sealing gasket and screws on one side are assembled, the product positioning base 108 is controlled by the telescopic rotating cylinder 107 to drive the control valve 8 to be assembled to flip 180°. After the flip is in place, the sealing gasket mounting hole on the product positioning base 108 is used to drive the control valve 8 to be assembled. The assembly of the sealing gasket and screws on the back of valve 8 is the same as the front assembly. After completing the assembly of the double-sided seals and screws of a control valve 8 to be assembled, each component in the entire device is controlled to automatically return to the initial state.

The conveying control process of the sealing pad in the present invention is as follows: the sealing pad moves forward from the sealing pad automatic feeding tray according to a specific state, the sealing pad automatic feeding controller accepts the opening signal from the programmable controller and the mold suppression module, and the sealing pad moves forward After arriving at the sealing pad direct vibration mechanism, it continues to be delivered to the sealing pad positioning device in sequence. After it is in place, the optical fiber sensor sends a signal to the programmable controller and the mold suppression module. The vacuum sealing pad mechanism receives the signals from the programmable controller and the mold suppression module. After absorbing the signal, the sealing gasket enters the suction device, and then the programmable controller and the mold suppression module control the rotating cylinder according to the program logic, driving the sealing gasket to the positioning base directly above the product, and the programmable controller and the mold suppression module control the vacuum according to the program logic. Take the sealing mechanism to quickly release the sealing gasket, and the sealing gasket enters the control valve to be assembled on the product positioning base.
