The translation cylinder drives the lifting support 511 to move horizontally, and then drives the lifting cylinder to move horizontally; the lifting cylinder can drive the material taking head 530 to move vertically, so as to make the material taking head 530 ascend to horizontally move the material taking head 530, or make the material taking head 530 descend to take or place the O-ring 3000.

[0046] In the embodiment, the lifting support 511 is vertically provided with a lifting slide rail 512, and the piston rod of the lifting cylinder is connected with a lifting sliding block 521. The lifting sliding block 521 is provided with a sliding groove, the lifting sliding block 521 is slidably matched with the lifting slide rail 512 through the sliding groove, and the material taking head 530 is arranged below the lifting sliding block 521. In this way, the lifting sliding block 521 and the lifting slide rail 512 are matched to vertically guide the material taking head 530, so that the material taking head 530 is more stable when being driven by the lifting driver 520 to ascend or descend.

[0047] Referring to Figure 3 and Figure 4In the embodiment, two O-ring loading areas 120, two assembly areas 110 and two material taking heads 530 are arranged, each O-ring loading area 120 is adapted to position one O-ring 3000, each assembly area 110 is adapted to position one cover 2000 through one limiting assembly 400, and the two material taking heads 530 are arranged above the two covers 2000 correspondingly.

[0048] The two assembly areas 110 are arranged in sequence along the moving direction of the cover 2000 and parallel to the first support plate 130, and correspondingly, the two O-ring loading areas 120 and the two material taking heads 530 are also arranged along the moving direction of the cover 2000 and parallel to the first support plate 130. When the assembly mechanism 1000 assembles the O-ring 3000 each time, the two material taking heads 530 respectively load the O-ring 3000 into the upper and lower ring grooves 2210 of the two covers 2000, so that the cover 2000 realizes the assembly of the O-ring 3000 in the upper and lower ring grooves 2210 after passing through the two material taking heads 530; thereby realizing the assembly of the double O-rings 3000 of the cover 2000, and the double material taking heads 530 work synchronously to improve the assembly efficiency.

[0049] Specifically, the two material taking heads 530 are defined as a first material taking head 530a and a second material taking head 530b, and the first material taking head 530a and the second material taking head 530b are both connected below the lifting sliding block 521 of the lifting driving part 520. Along the moving direction of the cover 2000, the first material taking head 530a is arranged upstream of the second material taking head 530b, and the vertical distance from the first material taking head 530a to the lower ring groove 2210 of the cover 2000 is the same as the vertical distance from the second material taking head 530b to the upper ring groove 2210 of the cover 2000, so that when the first material taking head 530a assembles the O-ring 3000 in the lower ring groove 2210 of the cover 2000 below it, the second material taking head 530b synchronously assembles the O-ring 3000 in the upper ring groove 2210 of the cover 2000 below it, and the cover 2000 realizes the assembly of the double O-rings 3000 by passing through the first material taking head 530a and the second material taking head 530b in sequence, and in this process, it is not necessary to repeatedly adjust the material taking head 530 to adapt to the installation requirements of the upper O-ring 3000 and the lower O-ring 3000, and through one vertical lifting mechanism, the two material taking heads 530 can be linked to synchronously assemble the O-ring 3000 in the upper and lower ring grooves 2210 of different covers 2000, thereby improving the assembly efficiency.

[0050] In addition, in other embodiments, only one material taking head 530 can be arranged, and the height of the material taking head 530 is controlled to be different by program control when it is lowered twice in front and back, so as to respectively send the O-ring 3000 to the upper ring groove 2210 and the lower ring groove 2210 of the cover 2000.

[0051] Reference Figures 3 to 5In the embodiment, the material taking head 530 comprises pneumatic clamping jaws 531 and material taking petals 532. The pneumatic clamping jaws 531 comprise a driving cylinder body 5311 and a plurality of driving jaws 5312 connected to the driving cylinder body 5311. The driving cylinder body 5311 is a pneumatic cylinder body, and the driving cylinder body 5311 can drive the driving jaws 5312 to move towards or away from each other in the radial direction of the driving cylinder body 5311. The material taking petals 532 are in a circular arc shape and are connected to the driving jaws 5312 one by one, so that when the plurality of driving jaws 5312 move towards each other, the spacing between the plurality of material taking petals 532 gradually decreases, until the plurality of material taking petals 532 abut each other and form a circular shaft suitable for inserting into the O-ring 3000. At this time, the lifting driving part 520 can drive the circular shaft formed by the plurality of material taking petals 532 to insert into the O-ring 3000. When the driving jaws 5312 move away from each other, the spacing between the plurality of material taking petals 532 increases, so that the plurality of material taking petals 532 tension the O-ring 3000, achieving grabbing of the O-ring 3000.

[0052] When grabbing the O-ring 3000, the inner circle of the plurality of material taking petals 532 forms a cylindrical cavity 533 with a diameter greater than the outer diameter of the column body 2200 of the cover 2000, so that the material taking head 530 can be sleeved on the column body 2200 of the cover 2000 when moving downward. At this time, the lower end of the material taking petals 532 is flush with the upper edge of the annular groove 2210 on the column body 2200, and the O-ring 3000 tensioned by the outer periphery of the material taking petals 532 can be driven downward into the annular groove 2210 by the lower pressing part 540, achieving automatic assembly of the O-ring 3000.

[0053] Referring to Figure 3 and Figure 4 In the embodiment, the lower pressing part 540 comprises a lower pressing cylinder 541 and a lower pressing plate 542. The cylinder body of the lower pressing cylinder 541 is connected to the driving end of the lifting driving part 520, and specifically in the embodiment, the cylinder body of the lower pressing cylinder 541 is connected to the lifting slider 521, so that the lower pressing part 540 and the material taking head 530 can move vertically together under the driving of the lifting cylinder. The piston rod of the lower pressing cylinder 541 is connected to the lower pressing plate 542 to drive the lower pressing plate 542 to vertically ascend and descend relative to the material taking head 530.

[0054] The lower pressing plate 542 is provided with a lower pressing cylinder 543 sleeved on the material taking head 530. In the embodiment, two lower pressing cylinders 543 corresponding to the material taking head 530 are provided. When the material taking head 530 is sleeved with the O-shaped ring 3000, the distance from the outer periphery of the material taking petal 532 to the inner wall of the lower pressing cylinder 543 is less than the thickness of the O-shaped ring 3000. Thus, the lower pressing plate 542 can be driven to move by the lower pressing member 540, so that the lower pressing cylinder 543 sleeved on the material taking head 530 moves vertically relative to the material taking head 530, and then the O-shaped ring 3000 on the material taking head 530 is pressed downward, so that the O-shaped ring 3000 is separated from the material taking head 530 and enters the annular groove 2210 on the cover 2000, and the assembly of the O-shaped ring 3000 is realized.

[0055] With reference to Figure 3 and Figure 6 In the embodiment, the limiting assembly 400 is arranged on one side of the first supporting plate 130. The limiting assembly 400 comprises a limiting plate 410 and a limiting cylinder 420. The cylinder body of the limiting cylinder 420 is fixed on the rack 100, and the piston rod of the limiting cylinder 420 is arranged perpendicularly to the first supporting plate 130. The limiting plate 410 is connected to the piston rod of the limiting cylinder 420, and an arc groove 411 engaging with the cover body 2100 of the cover 2000 is arranged on the limiting plate 410. The limiting cylinder 420 can drive the limiting plate 410 to move towards the assembly area 110 on the first supporting plate 130, so that the cover 2000 at the corresponding position is embedded in the arc groove 411 on the limiting plate 410, and then the cover 2000 is not easy to move relative to the assembly area 110, so as to facilitate the assembly of the O-shaped ring 3000.

[0056] With reference to Figure 7 The assembly mechanism 1000 further comprises a control assembly 600. The control assembly 600 comprises a blocking block 610 and a blocking cylinder 620. The blocking block 610 is arranged on the upstream of the assembly area 110 (i.e. the side where the cover 2000 moves in), and the blocking cylinder 620 is adapted to drive the blocking block 610 to move onto the first supporting plate 130, so as to block the cover 2000 in the moving path of the cover 2000. When the cover 2000 exists in the assembly area 110, the cover 2000 stops inputting to avoid affecting the assembly of the O-shaped ring 3000.
