[0053] Based on this, a typical working process of the present invention is as follows:

[0054] S1: As Figure 1 , Figure 2 and Figure 20 As shown, the conveyor belt 32 transports the housing 7 from the external material preparation equipment to the housing loading station 3 along the length of the housing 7 with the cavity end facing down. The industrial camera 316 on the picking robot 31 takes pictures of the housing 7 in the range of the end of the conveyor belt 32. Then, the first housing gripper 317 and the second housing gripper 318 respectively pick up a housing 7. Then, the picking robot 31 moves to the position above the initial position of the rotating mechanism 2, adjusts the housing 7 to the set posture according to the image taken by the industrial camera 316, and then inserts the housing 7 into the positioning block 233 of the housing tooling 23. The above actions are repeated in sequence to realize the automatic loading of the housing 7.

[0055] S2: As Figure 1 and Figure 21 As shown, the rotating mechanism 2 drives the housing 7 to rotate to the lower position of the secondary positioning station 4; the first pressing cylinder 431 drives the "L"-shaped pressing block 432 to press the top plane of the housing 7 to ensure that the housing 7 is correctly fitted onto the positioning block 233.

[0056] S3: As Figures 1-19As shown, the rotating mechanism 2 drives the housing 7, after secondary positioning, to rotate below the spring pressing station 5; the spring feeding mechanism 51 feeds the spring 8 into the guide plate 5229 of the combing mechanism 522 with the irregular torsional structure facing upwards, at which time the lower end of the spring 8 enters the feeding groove 52272 of the feeding block 5227; when the four first detection optical fibers 52211 on the optical fiber mounting block 52210 detect four different springs 8, the first slide cylinder 5222 drives the guide plate 5229. The four springs 8 inside the feeding block 5227 move to the right of the comb plate 5228. The tops of the springs 8 that are close together enter the first guide channel 52281, pass through the comb, and then pass through the second guide channel 52382, which separates the springs 8 at equal intervals. The spacing between the springs 8 is basically the same as the spacing of the spring slots on the housing 7. Then the second slide cylinder 5225 extends downward to drive the feeding block 5227 out of the lower part of the springs 8. At this time, the third slide cylinder 5232 retracts from the initial extended state to drive the pre- The pressing structure 5236 moves to the side of the spring 8, then the first slide cylinder 5222 resets, and then the fourth slide cylinder 5234 extends to drive the pre-pressing structure 5236 to press the spring 8 onto the stop structure 5237. At this time, the isolation teeth 523621 of the pre-pressing structure 5236 extend into the gaps between the fixing teeth 523721 of the fixing tooth plate 52372, realizing the secondary positioning of the spring 8. At this time, the first slide cylinder 5222 has been reset, and then the vertical cylinder 5214 extends to drive the clamping structure 5237. The material positioning mechanism 523 moves vertically downwards as a whole. At this time, the four springs 8 are pressed into the housing 7 simultaneously under the contact action of the arc-shaped pressing groove 52383 of the pressing block 5238. The springs 8 are pressed into place by interference fit until the lower end face of the positioning rod 52310 contacts the upper end face of the positioning post 232. After the springs 8 enter the housing 7, the bottom will contact the pressing detection rod 236 and move downwards. When the adjusting nut 239 at the lower end of the pressing detection rod 236 is detected by the second detection fiber optic 535, the spring pressing is qualified; otherwise, it is unqualified.

[0057] S4: The rotating mechanism 2 drives the housing 7 of another spring to be pressed on its rotating plate to rotate to the bottom of another spring pressing station 5, and performs the same steps as in S3. When the device is running continuously, the two spring pressing stations 5 work simultaneously.

[0058] S5: As Figure 1 , Figures 16-19 and Figure 22As shown, the rotating mechanism 2 moves the product with the pressed spring to below the unloading station 6. At this time, the ejector cylinder 61021 of the ejector component 610 pushes the push rod 235 through the ejector rod 61023, and the top surface of the push rod 235 ejects the product. Then, the fifth slide cylinder 62 moves the third housing gripper 68 to above the product, and the seventh slide cylinder 66 moves the third housing gripper 68 downward along the Z direction to the gripping position. Then, the third housing gripper 68 grips the product, and the seventh slide cylinder 66 moves upward. Reset; then the fifth slide cylinder 62 resets, and according to step S3, if the product is qualified, the third housing gripper 68 opens, and the product slides down the second feed cylinder 693 into the qualified product box of the material box 694; if the product is unqualified, the sixth slide cylinder 64 extends and drives the third housing gripper 68 to move above the first feed cylinder 692, the third housing gripper 68 opens, and the product slides down the first feed cylinder 692 into the unqualified product box of the material box 694; then each cylinder resets, completing the product classification and unloading.

[0059] The above process repeats itself to achieve automatic assembly of reed 8.
