Description

Technical Field

[0001] The present technical solution relates to the technical field of submersible pump assembly equipment, and in particular to an O-ring feeding device and a feeding method. Background Art

[0002] A submersible pump is a type of pumping equipment specifically used to extract and transport water deep into groundwater. It usually cleverly integrates the motor and the pump body.

[0003] Existing submersible pumps have a very wide range of applications and are often used in many fields such as farmland irrigation and drainage, water circulation in industrial and mining enterprises, urban water supply and drainage systems, and sewage treatment. Before starting the submersible pump, a key step is to ensure that the suction pipe and the inside of the pump body are completely filled with liquid, and the end must also be tightly sealed by the end cover. In order to further enhance the sealing effect, an O-ring is often installed on the end cover for sealing.

[0004] In order to improve the installation efficiency, the current O-ring installation method is usually mechanical automatic installation. The O-ring itself has certain elasticity and flexibility. Due to its special material, it is easy to have position deviation during the automatic feeding process, and it is difficult to accurately align with the installation position. The feeding positioning effect is poor, resulting in low installation efficiency. Summary of the invention

[0005] In order to improve the problem that the O-ring has poor positioning effect during loading due to its elasticity and flexibility, resulting in low installation efficiency, the technical solution provides an O-ring loading device and a loading method.

[0006] The purpose of this technical solution is achieved in this way:

[0007] An O-ring feeding device is used to put the O-ring on the outside of the adapted oil tank cover, comprising a frame and an O-ring feeding device, which is arranged on the frame and is used to store and transport the O-ring;

[0008] An O-ring transfer device is arranged on the frame, and a clamp mechanism for clamping the O-ring is arranged at the lower part of the O-ring transfer device, which is used to clamp the O-ring from the O-ring feeding device to the support ring positioning device;

[0009] A support ring positioning device, which is arranged beside the support ring positioning device and is used to stretch and position the O-ring clamped by the clamp mechanism;

[0010] The expansion ring installation device is arranged beside the support ring positioning device. The expansion ring installation device includes an expansion ring assembly, a mounting assembly and a driving assembly. The driving assembly drives the expansion ring assembly to expand the O-ring on the support ring positioning device, so that the mounting assembly installs the O-ring on the oil tank cover.

[0011] Through the above technical solution, when the O-ring feeding device and the feeding method are used normally, the O-ring feeding device is prepared with O-ring materials, which drives the O-rings to be transported one by one to the preset positions on the frame, and the O-ring transfer device drives the clamp mechanism at its lower part to accurately clamp an O-ring located on the frame and transfer it to the support ring positioning device. The support ring positioning device then stretches and expands the O-ring, and then releases the O-ring. Since the O-ring itself has a certain elastic force, it naturally rebounds to a more central position, thereby determining the positioning of the O-ring before installation and improving the subsequent support ring accuracy.

[0012] The expansion ring installation device drives the expansion ring assembly arranged at the bottom thereof to approach the O-ring on the support ring positioning device through the driving assembly, and expands the O-ring. The O-ring has a certain elastic force. The driving assembly moves the expansion ring installation device close to the oil tank cover, and the installation assembly sets the O-ring to the outside of the matching oil pipe cover, thereby completing the installation of the O-ring, improving the positioning effect of the O-ring during installation, and improving the installation efficiency.

[0013] Preferably, the support ring positioning device comprises a mounting frame 1 and a support ring assembly arranged on the mounting frame 1;

[0014] The upper end of the mounting frame 1 is provided with a material tray portion, the material tray portion is provided with a plurality of movable grooves along the circumferential direction, and the support ring assembly is arranged at the lower part of the material tray portion;

[0015] The support ring assembly includes a support ring driving member, a rotating shaft, and a support ring member sliding under the movable groove, the rotating shaft is provided with threaded segments with opposite spiral directions at both ends, the support ring member is provided with two, the support ring members are respectively threadedly connected to the corresponding threaded segments, the support ring member has a support ring column, and the upper ends of the two support ring columns pass through the corresponding movable grooves;

[0016] The support ring driving member drives the two support ring members to move closer to or farther from each other through the rotating shaft, thereby realizing the positioning of the O-ring on the material tray part.

[0017] Through the above technical solution, after an O-ring is placed flat on the upper end surface of the tray portion of the mounting frame, the two support ring members both pass upward through the movable groove of the tray portion to be located on the inner side of the O-ring ring, and the support ring driving member drives the rotating shaft to rotate. Based on the two support ring members respectively cooperating with the threaded segments with opposite spiral directions at both ends of the rotating shaft, the two support ring members slide synchronously in opposite directions, and the two support ring members located on the opposite sides form balanced expansion force points at both ends of the O-ring, which expands the O-ring to make its shape more stable and uniform, and the center of the O-ring is closer to the midpoint between the two support ring members, ensuring the smoothness and efficiency of the O-ring expansion process.

[0018] Preferably, the expansion ring installation device further comprises a second installation frame, a sliding platform is slidably provided on the second installation frame, a mounting seat is slidably provided on the sliding platform, and the sliding direction of the sliding platform is perpendicular to the sliding direction of the mounting seat.

[0019] The mounting seat is provided with the expansion ring assembly and the mounting assembly, the driving assembly includes a sliding driving component 1 and a sliding driving component 2, the sliding driving component 1 drives the sliding platform to move between a first position and a second position, and the sliding driving component 2 drives the mounting seat to rise and fall.

[0020] Through the above technical solution, the sliding drive component 1 drives the sliding table to slide, so as to drive the position adjustment of the expansion ring assembly and the installation assembly in the horizontal direction, and realizes the repeated switching movement of the position between the support ring positioning device and the oil tank cover. When the expansion ring assembly is located at the support ring positioning device, the sliding drive component 2 drives it downward to approach the O-ring to obtain the O-ring. When the expansion ring assembly is located at the oil tank cover, the sliding drive component 2 drives it downward to approach the oil tank cover, and the installation assembly installs the O-ring on the oil tank cover, which has better operating flexibility and improves installation efficiency.

[0021] Preferably, the expansion ring assembly comprises an expansion ring base, which is rotatably arranged at the lower part of the mounting seat, and a rotation driving member is provided on the mounting seat for driving the expansion ring base to rotate;

[0022] A movable block is slidably arranged at the lower part of the expansion ring base, and the movable block includes a plurality of movable blocks, the positions of the movable blocks correspond to the distribution of the movable grooves one by one, and the lower end of the movable block protrudes with a movable column;

[0023] The expansion ring driving member drives all the movable blocks to slide synchronously through the transmission structure, so that the movable column expands the O-ring outward

[0024] Through the above technical solution, the rotating driving member drives the expansion ring base to rotate and adjust around the axial direction, ensuring that the position of the movable column in each movable block can pass through the position of the movable groove one by one, and the expansion ring driving member drives all the movable blocks to slide outward. The sliding direction of each movable block radiates outward from the axis of the expansion ring base, so that the O-ring is evenly stretched from the inside by the movable column, the shape becomes more stable, and the tension is more uniform. The O-ring fastening ring is sleeved on the outside of all the movable columns, thereby realizing the O-ring acquisition and improving the installation accuracy and efficiency of the O-ring.

[0025] Preferably, the mounting assembly includes a stripping drive and a stripping plate arranged at the output end of the stripping drive, the stripping plate is slidably connected to the expansion ring base, and the expansion ring base is provided with a guide column penetrating the stripping plate to guide the sliding;

[0026] The stripping plate is provided with a plurality of stripping pieces, and the stripping pieces are movably arranged on the movable block in a one-to-one correspondence. An elastic piece is sleeved on the stripping piece, and the elastic force of the elastic piece makes the stripping piece have a tendency to press against the stripping plate;

[0027] The stripping drive member drives the stripping plate to slide, so as to push all the stripping members to move synchronously, so that the lower end of the stripping member separates the O-ring from the movable column.

[0028] Through the above technical scheme, when the expansion ring base approaches the oil tank cover to a specified height, the O-ring is surrounded in the fitting position, and the stripping drive drives the stripping plate to slide. The stripping plate overcomes the elastic force of the elastic part and compresses the elastic part. Based on the fact that the stripping part and the movable block are connected in a sliding fitting manner, the stripping part is pushed to move downward relative to the movable block until it is misaligned with the movable column. At this time, the lower end of the stripping part can push the O-ring against the movable column to separate the O-ring from the movable column, thereby realizing the ring sleeve on the outside of the oil tank cover.

[0029] Preferably, the transmission structure comprises a gear 1, a gear 2 and a spiral chassis rotatably arranged on the expansion ring base, the gear 1 is arranged at the output end of the expansion ring driving member, the gear 2 is meshed with the gear 1, and the gear 2 is coaxially arranged with the spiral chassis;

[0030] The spiral chassis is provided with a plurality of guide grooves, the positions of which correspond one to one with the movable block. The upper end of the movable block is provided with a guide portion, which is located in the guide groove. The extension direction of the guide groove guides the movement of the guide portion to achieve the sliding of the movable block.

[0031] Through the above technical solution, the expansion ring driving member drives gear one to rotate from the output end, and based on the meshing of gear one and gear two, gear two is driven to rotate, and the rotation of gear two drives the spiral chassis to rotate. Due to the different rotation directions of the spiral chassis, the guide groove on the spiral chassis guides the guide part in opposite directions, thereby realizing the gathering or expansion of the synchronous sliding of the movable block and improving the accuracy of the operation.

[0032] Preferably, the frame is provided with a material preparation bin and an edge detection device, the material preparation bin is connected to the discharge end of the O-ring feeding device, the edge detection device is mounted above the material preparation bin, and the detection end of the edge detection device faces the material preparation bin to identify the edge contour of the O-ring;

[0033] The O-ring transfer device comprises a transfer drive, a first crank arm disposed at the output end of the transfer drive, and a second crank arm rotatably disposed at the other end of the first crank arm;

[0034] The clamp mechanism is disposed at the end of the second crank arm, and the second crank arm drives the clamp mechanism to rise and fall through a screw structure.

[0035] Through the above technical solution, the material preparation bin is placed on the frame and has a box-shaped structure. The material preparation bin can accommodate the O-rings conveyed by the O-ring feeding device, limit the random scattering of the O-rings, and provide convenience for subsequent detection and clamping operations; the edge detection device has the function of contour detection, and its detection end is facing the O-ring on the frame. Based on the O-ring being a linear annular ring, it can identify and capture the overall contour information of the O-ring, so as to facilitate the clamping mechanism to clamp the edge of the O-ring, thereby improving the accuracy and efficiency of O-ring clamping and feeding.

[0036] The transfer drive drives the first crank arm to rotate through the output end. Since the other end of the first crank arm is hinged to the second crank arm, the second crank arm can also be relatively rotated and adjusted to form a structure with two-section crank arm swinging, which has a wider working coverage range and is more flexible in use. The second crank arm can drive the clamp mechanism to move above the preparation bin, or to above the tray part, to respectively perform the operations of obtaining the O-ring and placing it. Among them, when the clamp mechanism reaches the predetermined position, the clamping drive drives the clamp mechanism at its lower end to approach the O-ring, and the clamp mechanism clamps the edge of the O-ring. At this time, the transfer drive drives the first crank arm and the second crank arm to operate, and transfer the O-ring to the tray part to complete the transfer and installation tasks of the O-ring. During the whole process, the transfer drive, the first crank arm, the second crank arm and the clamp mechanism work together to achieve precise clamping and transfer of the O-ring, further ensuring the accuracy and efficiency of the installation.

[0037] Preferably, the O-ring feeding device comprises a feeding mechanism and a shifting mechanism, and the shifting mechanism drives the feeding mechanism to move;

[0038] The shift mechanism includes a sliding cylinder 1, a slide table sliding on the frame, a sliding cylinder 2, and a slide frame sliding on the slide table. The sliding cylinder 1 and the sliding cylinder 2 correspond to each other and drive the slide table and the slide frame to move respectively. The sliding direction of the slide table is perpendicular to the sliding direction of the slide frame.

[0039] The feeding mechanism comprises an O-ring material rack arranged on the slide, a storage rod arranged transversely on the O-ring material rack, and a material replenishing structure, wherein a plurality of O-rings are hung on the storage rod;

[0040] The feeding structure includes a feeding drive and a feeding plate slidably connected to the O-ring material rack. The feeding drive drives the feeding plate to slide along the length direction of the O-ring material rack to push the O-ring at the front end to separate from the storage rod.

[0041] Through the above technical scheme, the O-ring feeding device is installed on the frame, and a number of O-rings are neatly hung on the storage rod in the feeding mechanism for storage. The sliding cylinder 1 drives the slide to slide, driving the slide to move in the horizontal direction, and the sliding cylinder 2 drives the slide to slide, driving the feeding mechanism to move in the horizontal direction perpendicular to the sliding direction of the slide, thereby realizing the position adjustment of the feeding mechanism between the two axes, improving the positioning accuracy, and improving the flexibility of the feeding mechanism to move in the two-dimensional plane.

[0042] When the front end of the storage rod is located above the preparation bin, the feeding drive drives the feeding plate to slide along the length direction of the O-ring rack. This action causes the feeding plate to push the O-rings arranged on the storage rod forward, ensuring that the O-rings move forward step by step in a predetermined order and fall into the preparation bin below (the preparation bin is located on the rack and adjacent to the rack), thereby achieving continuous replenishment and feeding of O-rings, automated operation, and improved production efficiency.

[0043] Preferably, the O-ring material rack is further provided with a material limiting structure, which includes a material limiting driving member and a material limiting plate sliding on the O-ring material rack, and the material limiting plate is arranged in alignment with the end of the material storage rod through the opening of the O-ring material rack;

[0044] The material limiting driving member drives the material limiting plate to move, so as to change the size of the clearance distance between the material limiting plate and the material storage rod.

[0045] Through the above technical scheme, the material limiting driving member in the material limiting structure drives the material limiting plate to slide on the O-ring material rack, adjusts the interval between the material limiting plate and the end of the storage rod, and realizes effective control of the O-ring supply through precise regulation. When there is a gap, the O-ring can pass through to ensure that an appropriate number of O-rings are pushed to the working area each time. When there is no gap, the O-ring is restricted from leaving the storage rod, thereby realizing precise and orderly management of O-ring replenishment and material limiting.

[0046] Preferably, a feeding method is applied to the above-mentioned O-ring feeding device, comprising the following steps:

[0047] S1, the initial loading stage, the storage rod prepares the O-ring, the storage rod moves toward the preparation bin, the feeding plate pushes the O-ring into the preparation bin, and the loading of the O-ring is completed;

[0049] S3, the support ring stage, the support ring column of the support ring member slides in the movable groove, the two support ring columns move away from each other, the O-ring is stretched, the two support ring columns retreat, and the O-ring maintains a relatively centered position;

[0050] S4, the ring expansion stage, after the ring expansion base moves to the top of the mounting frame 1, it approaches the tray part, so that a plurality of movable columns are embedded in the corresponding movable grooves, and a plurality of movable columns slide in the movable grooves, and when all the movable columns move outward synchronously, the O-ring on the tray part is opened;

[0051] S5, during the installation phase, the expansion ring base moves to the top of the oil tank cover and moves the O-ring close to the outside of the oil tank cover. The stripping plate moves downward relative to the movable column. After the lower end surface of the stripping piece 20 coincides with the lower end surface of the movable column, the O-ring on the outside of the movable column is pushed out. The O-ring is tightly fitted on the outside of the oil pipe cover, and the installation phase is completed.

[0069] See also Figure 2 and Figure 3 The O-ring feeding device 2 includes a feeding mechanism 21 and a shifting mechanism 22. The shifting mechanism 22 drives the feeding mechanism 21 to move its position. In this embodiment, two groups of feeding mechanisms 21 are provided; the shifting mechanism 22 includes a sliding cylinder 1 221, a slide 222, a sliding cylinder 223 and a slide 224.

The sliding cylinder 1 221 is fixed on the frame 1 and the output shaft drives the slide 222 to slide.

[0070] There are two slides 224 distributed at intervals along the sliding direction of the slide 222. Both slides 224 are slidably installed on the slide 222 through a slide rail structure, and their sliding directions are perpendicular to the sliding direction of the slide 222 along the horizontal direction; two sliding cylinders 223 are installed on the slide 222 corresponding to the two slides 224, driving the corresponding slides 224 to slide, driving the feeding mechanism 21 on the slide 224 to slide along the second direction, and cooperating with the sliding cylinder 1 221 to drive the feeding mechanism 21 to slide along the first direction, thereby realizing the position change of the feeding mechanism 21 on the horizontal plane along the XY axis.

[0071] The feeding mechanism 21 includes an O-ring material rack 211, a storage rod 212 and a feeding structure 213. The O-ring material rack 211 is arranged at the upper end of the corresponding slide 224, and has two rod bodies extending horizontally forward.

The material limiting plate 152 is set on the output shaft of the material limiting driving member 151 and slides relative to the O-ring material rack 211, and its sliding direction is parallel to the sliding direction of the feeding plate 2132. The material limiting driving member 151 drives the material limiting plate 152 to slide. When the material limiting plate 152 abuts against the end of the material storage rod 212, the O-ring is limited from leaving the material storage rod 212. When the material limiting plate 152 leaves the material storage rod 212, a gap is left between the material limiting plate 152 and the end of the material storage rod 212 for the O-ring to pass through.

[0073] See also Figure 4 A material preparation bin 17 is provided on the frame 1, which is in the shape of a box. The top of the material preparation bin 17 is open and has no closed part. It is received below the discharge end of the O-ring feeding device 2 and can accommodate the O-rings pushed by the feeding plate 2132. A border detection device 11 is also provided on the frame 1, which is mounted above the material preparation bin 17.

The second curved arm 33 is located above the first curved arm 32, and a clamp mechanism 13 is provided at the other end away from the hinge. The second curved arm 33 has a built-in drive for driving the clamp mechanism 13, which drives the clamp mechanism 13 to rise and fall, and the clamp mechanism 13 is preferably an electric clamp. The transfer drive 31 drives the first curved arm 32 and the second curved arm 33 to move in coordination, thereby driving the clamp mechanism 13 to move to a specified position to open and close.

[0075] See also Figure 5The support ring positioning device 4 is arranged beside the O-ring transfer device 3, and includes a mounting frame 41 and a support ring assembly 42. The mounting frame 41 includes three layers, and pillars are provided at four corners between adjacent layers. The upper end of the mounting frame 41 has a tray portion 6, and its upper end surface is used for placing the O-ring clamped by the clamp mechanism 13. The tray portion 6 is penetrated by a plurality of movable grooves 7. The plurality of movable grooves 7 are distributed around the axis of the tray portion 6 along the circumferential direction at intervals, and the length direction of each movable groove 7 radiates outward with the same axis.

[0076] The support ring assembly 42 is arranged at the lower part of the material tray part 6, and includes a rotating shaft 423, a support ring driving member 421 and a support ring member 422.

The support ring member 422 has a support ring column 10, which is fixed to the upper end surface of the corresponding support ring member 422. The two support ring columns 10 pass through the two movable grooves 7 on the opposite sides one by one and then protrude from the material tray part 6. The support ring driving member 421 drives the rotating shaft 423 to rotate, so that the two support ring members 422 slide synchronously, driving the support ring columns 10 to slide closer or farther along the corresponding movable grooves 7. The support ring columns 10 on both sides slide away from each other to position the stretched O-ring.

The sliding driving member 1 531 drives the sliding platform 18 to move between a first position and a second position. When in the first position, the mounting seat 19 is located above the support ring positioning device 4. When in the second position, it is located above the oil tank cover. The sliding driving member 2 532 drives the mounting seat 19 to move up and down.

[0078] See also Figure 7 and Fig. 9 The expansion ring assembly 51 is installed on the mounting seat 19, and includes an expansion ring base 511, a movable block 512 and an expansion ring driving member 513. The expansion ring base 511 is rotatably connected to the bottom of the mounting seat 19 and is disc-shaped. A rotating driving member 8 is provided on the mounting seat 19, and its driving end is connected to the expansion ring base 511 to drive the expansion ring base 511 to rotate axially.

[0079] A plurality of movable blocks 512 are slidably arranged at the lower part of the expansion ring base 511 through a slide rail structure. In this embodiment, six movable blocks 512 are provided. The six movable blocks 512 are distributed at intervals around the axial direction of the expansion ring base 511. The position of each movable block 512 corresponds one by one to the position distribution of the movable groove 7. A movable column 14 protrudes from the lower end of each movable block 512, and the cross-sectional size of the movable column 14 matches the groove width of the movable groove 7.

[0080] The expansion ring driving member 513 drives the movable block 512 to slide. The specific driving method is to set a transmission structure 24 in the expansion ring base 511, such as Figure 8 As shown, it includes gear 1 241, gear 242 and spiral chassis 243. Gear 1 241 is arranged on the output shaft of the expansion ring driving member 513 and is coaxial. Gear 242 is meshed with gear 1 241. Gear 242 is coaxial with spiral chassis 243. Spiral chassis 243 is located below gear 242. The expansion ring driving member 513 drives to rotate, and the spiral chassis 243 is driven to rotate by gear 1 241 and gear 2 242. The spiral chassis 243 is provided with a plurality of guide grooves 25. The positions of the guide grooves 25 correspond to the movable blocks 512 one by one. Each movable block 512 has a guide portion 26 at the upper end, which is located in the corresponding guide groove 25. The guide portion 26 is guided by the arc-shaped extension direction of the guide groove 25 to move in a preset direction, thereby driving all movable blocks 512 to slide synchronously, so that the movable column 14 expands the O-ring outward.

[0081] See also Figure 7 and Fig.10 The mounting assembly 52 includes a stripping drive member 521 and a stripping plate 522. The stripping plate 522 is located below the expansion ring base 511. The expansion ring base 511 is provided with a plurality of guide posts 9 that pass through the stripping plate 522 to guide the sliding movement. The stripping plate 522 is arranged on the output shaft of the push drive member. A plurality of stripping members 20 are arranged below the stripping plate 522. The positions of the stripping members 20 correspond to the movable blocks 512 one by one. Each stripping member 20 is slidably sleeved on the corresponding movable block 512. Each stripping member 20 is sleeved with an elastic member 23. One of the elastic members 23 One end abuts against the movable block 512, and the other end makes the elastic force push the stripping member 20 to have a tendency to press against the lower end surface of the stripping plate 522. When the stripping driving member 521 drives the stripping plate 522, the stripping plate 522 slides downward along the guide column 9, and the stripping plate 522 overcomes the elastic force of each elastic member 23 to compress the elastic member 23, so as to push all the stripping members 20 to move downward synchronously. When the stripping member 20 passes the movable block 512, its lower end pushes the O-ring. When the lower end surface of the stripping member 20 is lower than the movable block 512 in the horizontal direction, the O-ring is detached from the movable column 14.

[0082] The specific working process of this program is as follows:

[0083] The present technical solution prepares a plurality of O-rings on the O-ring feeding device 2, which drives the O-rings to be transported one by one to the preset positions on the frame 1, and the O-ring transporting device 3 drives the clamping mechanism 13 at its lower portion to accurately clamp an O-ring located on the frame 1, and transports it to the support ring positioning device 4, and the support ring positioning device 4 then stretches and expands the O-ring, and then releases the O-ring. Since the O-ring itself has a certain elastic force, it naturally rebounds to a more central position to determine the positioning of the O-ring before installation, and the expansion ring installation device 5 drives the expansion ring assembly 51 at its lower portion to approach the O-ring on the support ring positioning device 4 to expand the O-ring. The O-ring has a certain elastic force, and the sliding drive part 2 532 drives the expansion ring installation device 5 to slide toward the oil tank cover, and the expansion ring installation device 5 puts the O-ring on the outside of the matching oil pipe cover, thereby completing the installation of the O-ring, improving the positioning effect of the O-ring during installation, and improving the installation efficiency.

[0084] A feeding method, applied to the above-mentioned O-ring feeding device, comprises the following steps:

[0085] S1, in the initial loading stage, the O-rings are stored on the material storage rod 212, and the sliding cylinder 1 221 drives the slide 222 to move horizontally along the first direction, and the sliding cylinder 223 drives the slide 224 to move along the second direction perpendicular to the first direction, and the left and right positions and the front and back positions of the loading mechanism 21 are adjusted until the front end of the material storage rod 212 is directly above the position of the material preparation bin 17, and the material limiting driving member 151 drives the material limiting plate 152 to move, and the material limiting plate 152 slides forward along the material storage rod 212, leaving a gap between the material limiting plate 152 and the material storage rod 212, and the material replenishing driving member 2131 drives the material replenishing plate 2132 to slide along the O-ring material rack 211, and the material replenishing plate 2132 applies a forward thrust to all the O-rings on the material storage rod 212 until the front end O-ring passes through the gap and falls into the material preparation bin 17, and the O-ring output rate is limited by controlling the gap size;

[0086] S3, material transfer stage, the edge detection device 11 performs detection and identification work, and performs contour scanning on the O-ring in the preparation bin 17. The scanning process can accurately capture the position information of the edge of the O-ring, and transmit the information to the O-ring transfer device 3. The transfer drive 31 drives the first curved arm 32 and the second curved arm 33 to rotate in coordination until the clamp mechanism 13 is directly above the position of the O-ring. The clamp mechanism 13 clamps the O-ring downward and then leaves the preparation bin 17 upward. The clamp mechanism 13 carries the O-ring to move above the material tray 6 and releases the O-ring, completing the clamping action of the O-ring.

[0087] S3, ring support stage, the ring support driving member 421 drives the two ring support members 422 to move away from each other, the ring support columns 10 on both sides slide in the movable groove 7, the O-ring is stretched, the two ring support columns 10 retreat, and the O-ring maintains a relatively centered position due to elasticity, thereby completing the accurate positioning of the O-ring on the tray portion 6;

[0088] S4, expansion ring stage, the sliding drive member 1 531 drives the sliding platform 18 to slide, so that the expansion ring base 511 is located directly above the material tray portion 6, and the sliding drive member 2 532 drives the expansion ring assembly 51 to approach the material tray portion 6, and the movable columns 14 can all pass through the movable grooves 7 that are arranged in a one-to-one correspondence. The expansion ring drive member 513 drives all the movable blocks 512 to expand outward synchronously through the transmission structure 24, and the O-ring located on the material tray portion 6 is opened;

[0089] S5, during the installation phase, the sliding drive component 531 drives the sliding platform 521 to make the expansion ring base 511 located just above the oil tank cover, and slides and moves the O-ring close to the outside of the oil tank cover. The stripping drive component 521 drives the stripping plate 522 downward along the guide column 9, overcomes the elastic force of the elastic component 23 and pushes the stripping component 20. After the lower end surface of the stripping plate 522 coincides with the lower end surface of the movable column 14, the O-ring located on the outside of the movable column 14 is pushed out, and the O-ring is tightly fitted on the outside of the oil pipe cover. The installation phase is completed.
