[0037] Referring to Figure 2 And Figure 3 The O-ring taking mechanism 1000 of the embodiment comprises a rack 100, a taking head 200, a translation driving part 300, a lifting driving part 400 and a pressing part 500.

The upper area 110 is connected to an O-ring feeding mechanism, and the O-ring feeding mechanism transports O-ring 3000 to the upper area 110.

[0039] The translation driving part 300 is arranged on the rack 100 and is used to drive the taking head 200 to move between the upper area 110 and the assembly area 120. The lifting driving part 400 and the taking head 200 are arranged on the driving end of the translation driving part 300, the lifting driving part 400 is connected to the taking head 200 and is used to drive the taking head 200 to vertically lift and lower. The taking head 200 is used to grab O-ring 3000, and the pressing part 500 is used to press O-ring 3000 on the taking head 200 to the workpiece 2000 to be assembled.

[0040] In the O-ring taking mechanism 1000 of this embodiment, when the O-ring 3000 is taken, the translation driving member 300 drives the taking head 200 to move above the feeding area 110, the lifting driving member 400 drives the taking head 200 to descend to the O-ring 3000 so that the taking head 200 grabs the O-ring 3000, then the lifting driving member 400 drives the taking head 200 to ascend, the translation driving member 300 drives the taking head 200 to move to the assembling area 120, the lifting driving member 400 drives the taking head 200 to descend and move above the workpiece 2000 to be assembled, and the pressing member 500 moves downward relative to the taking head 200 to press the O-ring 3000 on the taking head 200 into the annular groove 2100 of the workpiece 2000 to be assembled, thereby achieving the taking of the O-ring 3000 and the assembling of the O-ring 3000 into the annular groove 2100 of the workpiece 2000 to be assembled.

[0041] With reference to Figure 2 and Figure 3 In this embodiment, the translation driving member 300 comprises a translation cylinder, the rack 100 is provided with a support frame 130, the cylinder body of the translation cylinder is fixed to the support frame 130, and the taking head 200 and the lifting driving member 400 are connected to the piston rod of the translation cylinder. When the piston rod of the translation cylinder extends or retracts, it can drive the taking head 200 and the lifting driving member 400 to move horizontally relative to the support frame 130, so that the taking head 200 moves between the feeding area 110 and the assembling area 120. In addition, in other embodiments, the horizontal driving member can also be a linear driving member such as an electric cylinder, a gear and rack, or a motor lead screw mechanism.

[0042] In this embodiment, the lifting driving member 400 comprises a lifting cylinder, the lifting cylinder is vertically arranged, the piston rod of the translation cylinder is connected to a lifting support 310, the cylinder body of the lifting cylinder is fixed to the lifting support 310, and the piston rod of the lifting cylinder is connected to the taking head 200. When the piston rod of the lifting cylinder extends or retracts, it can drive the taking head 200 to vertically ascend or descend, so that the taking head 200 grabs the O-ring 3000 or moves above the workpiece 2000 to be assembled. In addition, in other embodiments, the lifting driving member 400 can also be a linear driving member such as an electric cylinder, a motor lead screw, or a gear and rack.

[0043] The lifting support 310 is provided with a lifting slide rail 311 extending vertically. The piston rod of the lifting cylinder is connected to a lifting sliding block 410, and the taking head 200 is fixedly arranged below the lifting sliding block 410.

[0044] The lifting sliding block 410 is provided with a slot matched with the lifting slide rail 311, so that the lifting sliding block 410 is slidably matched with the lifting slide rail 311. In this way, the lifting cylinder drives the lifting sliding block 410 and the taking head 200 to vertically ascend or descend more stably.

[0045] With reference to Figure 3 andFigure 4 In the embodiment, each of the material taking heads 200 comprises a pneumatic clamping jaw 210 and a plurality of material taking petals 220. The pneumatic clamping jaw 210 comprises a cylinder body 211 and a plurality of driving claws 212. The cylinder body 211 is in a cylindrical shape and is fixedly connected to the lower end of the lifting slide 410. A plurality of radially movable pistons are arranged in the cylinder body 211. Each of the pistons is correspondingly connected to one of the driving claws 212. Each of the driving claws 212 is correspondingly connected to one of the material taking petals 220. Thus, the plurality of material taking petals 220 can be driven by the pneumatic clamping jaw 210 to move towards or away from each other along the radial direction of the cylinder body 211.

[0046] In the embodiment, the lower end of each of the material taking petals 220 is in a circular arc shape. The plurality of material taking petals 220 enclose a circular shaft, so that the contact surface between the O-ring 3000 and the material taking petals 220 is relatively smooth and the O-ring 3000 is not easily worn. In the embodiment, four material taking petals 220 are arranged in a 1 / 4 cylindrical shape. Correspondingly, four driving claws 212 of the pneumatic clamping jaw 210 are arranged. When the pneumatic clamping jaw 210 drives the material taking petals 220 to move away from each other along the radial direction, the diameter of the circular shaft formed by the four material taking petals 220 increases. When the pneumatic clamping jaw 210 drives the material taking petals 220 to move towards each other along the radial direction, the diameter of the circular shaft formed by the four material taking petals 220 decreases. In other embodiments, the number of the material taking petals 220 can also be other suitable values greater than 1.

[0047] In the embodiment, when the material taking head 200 grabs the O-ring 3000, the material taking head 200 moves above the feeding area 110. The pneumatic clamping jaw 210 drives the plurality of material taking petals 220 to move towards each other, so that the diameter of the circular shaft enclosed by the material taking petals 220 decreases to be smaller than the inner diameter of the O-ring 3000. The lifting cylinder drives the material taking head 200 to move downward, so that the circular shaft formed by the plurality of material taking petals 220 is inserted into the O-ring 3000. Then, the pneumatic clamping jaw 210 drives the plurality of material taking petals 220 to move away from each other, so that the diameter of the circular shaft enclosed by the material taking petals 220 increases to expand the O-ring 3000. Thus, the material taking head 200 fixes the O-ring 3000 by tension to drive the O-ring 3000 to move. In the embodiment, when the O-ring 3000 is assembled, the O-ring 3000 is expanded by the material taking petals 220. The lower pressing member 500 presses the O-ring 3000, so that the O-ring 3000 is arranged in the annular groove 2100 of the workpiece 2000 to be assembled. Manual tightening of the expanded O-ring 3000 is not needed. Thus, the O-ring taking mechanism 1000 of the embodiment can automatically expand, feed and assemble the O-ring 3000, so that the labor cost is saved, the labor intensity is reduced, and the assembly efficiency is improved.

[0048] Reference Figure 2 to Figure 4In the embodiment, the material taking petals 220 are arc-shaped plates, so that the material taking petals 220 form a cylindrical avoiding cavity 230 inside the circular shaft. When the material taking head 200 is lowered to the workpiece 2000 to be assembled, the workpiece 2000 to be assembled can be inserted into the avoiding cavity 230 through program control, so that the upper edge of the annular groove 2100 on the workpiece 2000 to be assembled is just below the material taking petals 220, and when the lower pressing piece 500 presses the O-ring 3000 on the material taking petals 220, the O-ring 3000 just enters the annular groove 2100 after leaving the material taking petals 220, thereby ensuring the assembly precision of the O-ring 3000. In other embodiments, the material taking petals 220 can also be solid members, wherein the diameter of the material taking petals 220 is smaller, so that the pneumatic clamping jaw 210 can drive the material taking petals 220 to move away from each other to enable the workpiece to be assembled to be inserted into the gap between the material taking petals 220.

[0049] With reference to Figure 2 and Figure 3 The feeding area 110, the assembly area 120 and the material taking head 200 are each provided with two O-rings 3000, and each O-ring 3000 is adapted to be positioned and placed in the feeding area 110, and each assembly area 120 is adapted to be fixed and placed with a workpiece 2000 to be assembled through a limiting assembly. The limiting assembly can be a pneumatic cylinder clamping piece or a threaded locking piece, as long as it can fix the workpiece 2000 to be assembled in the assembly area 120. The two material taking heads 200 are correspondingly arranged above the two workpieces 2000 to be assembled, and the two material taking heads 200 are connected below the lifting slide 410. The two material taking heads 200 synchronously take the O-rings 3000 in the two feeding areas 110 and move the O-rings 3000 to the workpieces 2000 to be assembled in the two assembly areas 120, so as to improve the feeding and assembly efficiency of the O-rings 3000.

[0050] With reference to Figure 5 , the two material taking heads 200 are defined as a first material taking head 201 and a second material taking head 202, the workpiece 2000 below the first material taking head 201 is defined as a first workpiece 2001 to be assembled, and the workpiece 2000 below the second material taking head 202 is defined as a second workpiece 2002 to be assembled. The annular groove 2100 above the workpiece 2000 to be assembled is defined as a first annular groove 2110, and the annular groove 2100 below is defined as a second annular groove 2120.

[0051] In the embodiment, the vertical distance from the first pick-up head 201 to the second ring groove 2120 of the first workpiece 2001 is the same as the vertical distance from the second pick-up head 202 to the first ring groove 2110 of the second workpiece 2002. Thus, the lifting cylinder can drive the two pick-up heads 200 to move synchronously, so that when the first pick-up head 201 moves downward to the upper edge of the second ring groove 2120 of the first workpiece 2001, the second pick-up head 202 moves downward to the upper edge of the first ring groove 2110 of the second workpiece 2002. When the pressing member 500 presses, the two O-rings 3000 are pressed into the different ring grooves 2100 of the two workpieces 2000, respectively, and the workpieces 2000 can pass the first pick-up head 201 and the second pick-up head 202 in turn, so as to realize the assembly of the O-rings 3000 in the first ring groove 2110 and the second ring groove 2120.

[0052] In other embodiments, the vertical distance from the first pick-up head 201 to the first ring groove 2110 of the first workpiece 2001 can be the same as the vertical distance from the second pick-up head 202 to the second ring groove 2120 of the second workpiece 2002, and when the first pick-up head 201 moves downward to the upper edge of the first ring groove 2110 of the first workpiece 2001, the second pick-up head 202 moves downward to the upper edge of the second ring groove 2120 of the second workpiece 2002.

[0053] In other embodiments, the number of pick-up heads 200 can be one, and the height of the pick-up head 200 is controlled to be different when the pick-up head 200 picks up and places the O-rings 3000 twice in sequence, so as to send the O-rings 3000 to the first ring groove 2110 and the second ring groove 2120 of the workpiece 2000, respectively. In other embodiments, the number of pick-up heads 200 can be three or more, and some of the pick-up heads 200 are used to send the O-rings 3000 to the first ring groove 2110, and some of the pick-up heads 200 are used to send the O-rings 3000 to the second ring groove 2120.

[0054] Referring to Figure 3 , Figure 5 and Figure 6 , the pressing member 500 comprises a pressing cylinder 510 and a pressing plate 520. The cylinder body of the pressing cylinder 510 is connected to the driving end of the lifting driving member 400, and in the embodiment, the cylinder body of the pressing cylinder 510 is fixedly connected to the lifting slide block 410. The pressing plate 520 is arranged below the lifting slide block 410, and the piston rod of the pressing cylinder 510 is connected to the pressing plate 520, so that the pressing plate 520 can be driven to move vertically by the pressing cylinder 510.

[0055] The lower pressing plate 520 is provided with lower pressing cylinders 530, the number of the lower pressing cylinders 530 is same as that of the material taking heads 200, and the lower pressing cylinders 530 are correspondingly sleeved outside the material taking heads 200. The inner diameter of the lower pressing cylinder 530 is greater than the diameter of the circular shaft formed by the material taking petals 220, and when the material taking petals 220 move away from each other to tension the O-shaped ring 3000, the minimum distance between the lower pressing cylinder 530 and the material taking petals 220 is less than the thickness of the O-shaped ring 3000, so that the O-shaped ring 3000 can be pressed into the annular groove 2100 from the material taking petals 220 when the lower pressing cylinder 530 is lowered.

[0056] In the embodiment, the lower pressing plate 520 is specifically provided with two lower pressing cylinders 530, and the two lower pressing cylinders 530 are correspondingly sleeved outside the two material taking heads 200. The vertical distance from one of the lower pressing cylinders 530 outside the first material taking head 201 to the second annular groove 2120 of the first workpiece to be assembled 2001 is same as the vertical distance from one of the lower pressing cylinders 530 outside the second material taking head 202 to the first annular groove 2110 of the second workpiece to be assembled 2002. When the lower pressing cylinder 510 is pressed, the lower pressing cylinder 530 outside the first material taking head 201 can press the O-shaped ring 3000 into the second annular groove 2120 of the first workpiece to be assembled 2001, and the lower pressing cylinder 530 outside the second material taking head 202 can press the O-shaped ring 3000 into the first annular groove 2110 of the second workpiece to be assembled 2002. Thus, the same lower pressing cylinder 510 can drive two lower pressing cylinders 530 to press two O-shaped rings 3000 with different heights into corresponding annular grooves 2100.

[0057] Referring to Figure 6 The lower pressing plate 520 is provided with a guide sleeve 411, and a guide hole 412 penetrating through the upper and lower sides of the lifting slider 410 is formed in the guide sleeve 411.
