[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0028] The preferred embodiment of the oil seal press-fitting machine and method of the present invention, such as... Figure 1 As shown, see also Figures 2-5 The system includes a processing table 8, an oil seal feeding assembly 1 for feeding oil seals 2, a first transfer robot 80, an inner ring oiling assembly 81, an outer ring oiling assembly 82, a transfer station 83, a defective product recovery station 84, a second transfer robot 85, a vision recognition assembly 86, and a pressing assembly 87. The first transfer robot 80 includes a first swing gripper 800 and a second swing gripper 801 set on the same track (preferably, both the first swing gripper and the second swing gripper are equipped with a front and back detection sensor for detecting the front and back of the oil seal and a flipping cylinder; of course, the flipping can also be performed during the oil seal feeding stage). The outer ring oiling assembly 82, the inner ring oiling assembly 81, and the transfer station 83 are distributed along the movement trajectory of the first swing gripper 800. The defective product recovery station 84, the transfer station 83, and the pressing assembly 87 are distributed along the movement trajectory of the movable end of the second transfer robot 85.

[0029] Oil seal 2 is fed by oil seal feeding assembly 1. After the first swing gripper 800 of the first transfer robot 80 picks up the oil seal, the sensor on the first swing gripper 800 identifies the front and back of the oil seal. If the oil seal is reversed, the first swing gripper 800 is rotated to flip the oil seal. The first swing gripper 800 places the oil seal into the outer ring oiling assembly 82 for outer ring oiling and then returns to the oil seal feeding assembly. The second swing gripper 801 sends the oil seal into the inner ring oiling assembly 81 for inner ring oiling. The second swing gripper 801 places the oil seal with the inner ring oiling completed into the transfer station 83. The vision recognition assembly 86 performs visual recognition of the oil seal oiling. The second transfer robot 85 transfers the good oil seal from the transfer station 83 to the pressing assembly 87 for the oil seal pressing process and transfers the defective oil seal from the transfer station to the defective product recycling station 84.

[0030] By applying the layout method of this application, space can be utilized more reasonably, and the oil seal feeding, outer ring oiling, inner ring oiling, defective product detection and pressing can be integrated into one equipment, which improves processing efficiency and reduces the additional costs caused by separate multi-stage processing.

[0031] It should be noted that the above-mentioned swing grippers (first swing gripper 800 and second swing gripper 801) can perform the front and back identification operation of the oil seal in the oil seal feeding assembly, that is, the front and back identification is performed when the oil seal is put into the oil seal feeding assembly (it can be manual or mechanical identification operation); the first swing gripper 800 and second swing gripper 801 with front and back identification and flipping functions can use existing components, which will not be described in detail here; the pressing assembly 87 can use the existing pressing assembly for pressing oil seals into motor housings, which will not be described in detail here;

[0032] Furthermore, by employing the first swing gripper 800 and the second swing gripper 801, alternating material transfer can be achieved to improve efficiency and reduce waiting time. The alternating material transfer is explained as follows: when the second swing gripper moves the oil seal from the outer ring oiling assembly to the inner ring oiling assembly, the first swing gripper can move the oil seal from the oil seal feeding assembly to the outer ring oiling assembly; when the second swing gripper moves the oil seal from the inner ring oiling assembly to the transfer station, the first swing gripper can move the oil seal from the oil seal feeding assembly to the outer ring oiling assembly, or it can move the oil seal from the outer ring oiling assembly to the inner ring oiling assembly.

[0033] The preferred embodiment of the oil seal feeding assembly of the present invention, such as Figure 2 As shown, it includes a ring-shaped rotating turret 10, a first rotating component 11 that drives the ring-shaped rotating turret 10 to rotate, and a material handling component 12; the ring-shaped rotating turret 10 is provided with a plurality of longitudinally stacked guide columns 100 arranged in a ring; the material handling component 12 includes a material handling fork 120, a lateral moving unit 121 that drives the material handling fork to move laterally, and a lifting unit 122 that drives the lateral moving unit 121 to rise and fall; the lower end of the guide column 100 is provided with a boss 101 that cooperates with the material handling fork, and the outer diameter of the boss 101 is larger than the outer diameter of the guide column 100;

[0034] The novel oil seal feeding structure of this application allows multiple oil seals 2 to be stacked on each guide post 100. During feeding, the transverse unit 121 moves laterally with the picking fork 120, corresponding to the position of the protrusion 101 at the lower end of the guide post 100. Then, the lifting unit 122 drives the transverse unit 121 to rise gradually, and the picking fork 120 removes the oil seals 2 one by one. The oil seals can then be removed by external grippers or other equipment. The structure is simple and can store a large number of oil seals in batches, effectively reducing the labor intensity of workers and improving efficiency.

[0035] It should be noted that the transverse unit 121 can use existing components such as cylinders and linear push rods. Similarly, the lifting unit 122 can also use existing components such as linear push rods and linear motors, in addition to the lead screw assembly structure described below. Simple replacement of existing components based on this principle also falls within the scope of protection of this application.

[0036] Preferably, the oil seal feeding assembly further includes a detection component 13 for detecting whether there is an oil seal 2 on the guide column 100 rotated to the feeding position; the detection component 13 can be set up using the infrared beam method described below, or it can be other existing material sensors.

[0037] When using infrared beam detection, a first infrared beam detection component 130 can be set up to detect the material storage position of the oil seal at the bottom of the guide column 100 and a second infrared beam detection component 131 can be set up to detect the material storage position of the oil seal at the top of the guide column 100. The infrared rays emitted by the first infrared beam detection component 130 and the infrared rays emitted by the second infrared beam detection component 131 are both tangent to the rotation trajectory of the guide column 100. This layout can effectively detect materials without interfering with the normal rotation of the guide column, and disassembly and maintenance are extremely simple.

[0038] Preferably, the annular rotating material tower 10 includes a base plate 102 and a rotating platform 103. The base plate 102 is rotatably connected to the rotating platform 103. The first rotating component 11 includes a rotating motor, which is mounted on the rotating platform 103. The structure is simple and has good stability.

[0039] Preferably, the base plate 102 is disc-shaped, and the multiple guide posts 100 are arranged in a circular pattern.

[0040] Preferably, the movable end of the transverse unit 121 is provided with a longitudinal limiting plate 1210, and the picking fork 120 is provided at the upper end of the limiting plate 1210; the limiting plate 1210 serves two purposes: firstly, to connect and install the picking fork 120, and secondly, to contact and limit the edge of the base plate 102, so as to avoid excessive transverse movement and damage to the guide column 100.

[0041] Preferably, the material handling assembly 12 further includes a mounting bracket 123, on which a lifting unit 122 is provided. The lifting unit 122 includes a slide rail 1220 that is slidably connected to the transverse unit, a lead screw 1221 that drives the transverse unit 121 to rise and fall along the slide rail, and a lead screw motor 1222 that drives the lead screw. As mentioned above, the lifting unit can also adopt other existing forms.

[0042] The preferred embodiment of the oil seal outer ring oiling assembly of the present invention, such as... Figure 3 As shown, it includes a swing platform 3 and an oil box 4. The swing platform 3 is provided with a connecting shaft 30 that is detachably connected to the inner ring of the oil seal 2 and a second rotating component 31 that drives the connecting shaft 30 to rotate horizontally. The oil box 4 is provided with an opening groove 401, and an oiling component 400 is provided in the opening groove 401. The swing platform 3 is provided with a flipping component 32 that drives the second rotating component 31 to flip longitudinally. When the oil seal 2 located on the connecting shaft 30 flips longitudinally with the second rotating component 31, it can extend into the opening groove 401.

[0043] By applying the novel oil seal outer ring oiling structure of this application, the oil seal 2 is fed onto the connecting shaft 30 and connected. Then, the flipping component 32 drives the oil seal 2 to flip at a certain angle (preferably 90 degrees) and enter the opening groove 401 to contact the oiling part 400. The second rotating component 31 drives the connecting shaft 30 to rotate, thereby driving the oil seal 2 to rotate. The oiling work of the entire outer ring can be completed quickly. The overall equipment structure is extremely simple, the cost is low, the oiling effect is good, and the processing efficiency is high.

[0044] Preferably, the connecting shaft 30 is an air-expanding shaft, that is, after the oil seal is placed on the connecting shaft, the oil seal is quickly locked by venting the connecting shaft, so as to achieve the purpose of quick installation and quick removal; of course, it is understood that other existing structures can also be used, such as setting a damping sleeve on the shaft to form a connecting shaft, and damping the oil seal, etc., but the effect will be relatively worse. Simple replacement of existing structures based on the principle of this application also falls within the scope of protection of this application.

[0045] Preferably, the second rotating assembly 31 includes a mounting plate 310, on which a drive motor 311, a driving wheel 312, and a driven wheel 313 are mounted. The driven wheel 313 is rotatably connected to the mounting plate 310, and the driven wheel 313 is connected to the driving wheel 312 via a belt 314. The driving wheel 312 is driven by the drive motor 311, and the connecting shaft 30 is coaxially fixedly mounted in the inner hole of the driven wheel 313. The drive motor 311 drives the driving wheel 313 to rotate, which in turn drives the driven wheel 313 to rotate via the belt 314, thereby driving the connecting shaft 30 to rotate. The structure is simple, the drive reliability is good, and the accuracy is easy to control. More preferably, the drive motor is a stepper motor.

[0046] Preferably, the flipping assembly 32 includes a horizontally arranged rotary drive unit 320. The movable end of the rotary drive unit 320 is provided with a connecting plate 321 that connects to the mounting plate 310. The mounting plate 310 and the connecting plate 321 form an L-shaped area, and the drive motor 311 is located in the L-shaped area. This structural design saves space and can better hide the drive motor. It also helps to ensure that the overall center of gravity of the rotary assembly is relatively centered, which facilitates the flipping drive of the rotary drive unit 320.

[0047] Preferably, the oil seal outer ring oiling assembly further includes an oil inlet tank 42 and a peristaltic pump 43 that directs oil from the oil inlet tank 42 into the oil box; such as Figure 1 As shown in the figure (the oil inlet tank, peristaltic pump, and oil box connecting oil pipes are omitted), the oil is manually injected directly into the oil inlet tank 42, and then the peristaltic pump 43 is turned on to guide the oil into the oil box 4, thus completing the oil injection operation.

[0048] Preferably, the opening groove 401 is located on the top surface of the oil box 4, and the opening groove 401 is connected to one side surface of the oil box 4; this structural design allows for better insertion of the oil seal 2 and ensures good overall integrity. Preferably, the oiling component 400 is an oiling sponge, but it can also be replaced with other existing materials, such as an oiling cloth.

[0049] The oil box of the preferred embodiment of the present invention, such as Figure 4 As shown, see also Figure 3 The oil box 4 includes a first box body 40 and a second box body 41. The first box body 40 is located above the second box body 41. An oiling component 400 is provided inside the first box body 40. An opening groove 401 is provided on the upper surface of the first box body 40 to expose part of the oiling component 400. An oil inlet 402 is provided on the top or side wall of the first box body 40, which is directly opposite to the oiling component 400. An oil receiving port 410 is provided on the second box body 41 to receive the oil falling from the first box body 40.

[0050] The oil box of this application is divided into two boxes: a first box 40 and a second box 41. In use, oil is supplied to the oiling component 400 inside the first box 40 through the oil inlet 402 located at the top. Excess oil in the first box 40 overflows from the opening groove 401 and flows into the second box 41 through the oil inlet 410 for temporary storage. With the above structure, sufficient oil is ensured on the oiling component 400. In this way, the oil seal can be inserted into the opening groove 401 and simply rotated and wiped on the oiling component 400 to complete the outer ring oiling operation, thereby improving the oiling efficiency of the outer ring of the oil seal.

[0051] Preferably, a connection joint 411 can be provided on the second container 41 to connect to an external container via a pipe, so that the oil inside the second container can be transferred through the pipe, which can ensure the long-term continuous operation of the entire oil box.

[0052] Preferably, a preferred embodiment of the oil inlet is as follows: the bottom surface dimension of the first box 40 is smaller than the upper surface dimension of the second box 41, the upper surface of the second box 41 is provided with a receiving groove 412 that accommodates the bottom of the first box 40, and there is a gap between the side surface of the first box 40 and the inner wall of the receiving groove 412, the gap forming the oil inlet 410; with this structural design, the integrity can be guaranteed, the oil inlet can be made smaller while ensuring oil reception, reducing the probability of foreign objects entering, and the overall volume of the oil box can be made smaller;

[0053] Preferably, the first box 40 can also be fixedly connected within the receiving slot 412 to further improve the overall integrity;

[0054] Preferably, the opening groove 401 is connected to the side of the first box 40, and the oil inlet 410 is located directly below the opening groove 401. In this way, the size of the oil inlet can be further reduced, and only a gap needs to be set between the side surface of the first box 40 where the opening groove 401 is provided and the inner wall that accommodates the groove 412.

[0055] Of course, it is understandable that the above-mentioned implementation of the oil inlet is not the only one. Without considering the size of the oil inlet, there can be other settings, such as making the oil inlet large enough to cover the entire first box, or setting oil guide ropes, oil guide pipes, etc. on the first box to guide the overflowing oil into the oil inlet, etc. These are all feasible.

[0056] The preferred embodiment of the oil seal inner ring oiling assembly of the present invention, such as... Figure 4 As shown, it includes a mounting bracket 5, a detection mounting plate 50 is provided on the mounting bracket 5, a hollow grease column 51 is longitudinally inserted through the detection mounting plate 50, and a metering valve 52 for metering grease into the grease column 51 is provided on the mounting bracket 5 below the detection mounting plate 50; an annular step 510 for placing the oil supply seal is provided at the upper end of the grease column 51, and multiple grease outlet holes are evenly provided on the outer surface of the annular step 510.

[0057] By applying the novel oil seal inner ring oiling structure of this application, the metering valve 52 and the grease column 51 are integrated on a mounting bracket 5. In use, the oil seal 2 only needs to be positioned on the annular step 510, and then the metering valve 52 injects grease in a metered manner, and the grease in the grease column 51 is squeezed out from the grease outlet hole in a metered manner, which can ensure the uniformity of oiling while accurately controlling the amount of grease.

[0058] Preferably, mounting side plates 53 are respectively provided on both sides of the detection mounting plate 50, and infrared beam detectors 54 are provided on the mounting side plates 53 to detect whether there is a feeding oil seal 2 on the annular step 510; the structure is simple, and after the infrared beam detectors 54 detects the oil seal, they can send an electrical signal to the metering valve 52, which can be used as a trigger signal for the metering valve 52.

[0059] Preferably, the upper end of the grease column 51 is provided with a guide frustum 511 for guiding the oil seal into the annular step; this facilitates the placement of the oil seal 2.

[0060] Preferably, the mounting bracket 5 includes an L-shaped base 55, and longitudinal connecting plates 56 are evenly arranged on the outer surface of the longitudinal side of the base 55. The upper end of the detection mounting plate 50 is detachably connected to the connecting plate 56, and the metering valve 52 is detachably connected to the side surface of the connecting plate 56 opposite to the base. This facilitates disassembly and maintenance and reduces costs.

[0061] Preferably, the upper end of the metering valve 52 abuts against the lower surface of the detection mounting plate 50, and the inner surface of the base 55 is provided with a reinforcing block 57 connecting its lateral side and its longitudinal side; the overall integrity is good, ensuring the stability of the detection mounting plate 50 while providing a certain degree of protection for the metering valve 52.

[0062] An oil seal press-fitting method, applied to an oil seal press-fitting machine as described above, such as... Figure 6 As shown, it includes the following steps:

[0063] The oil seal is fed by the oil seal feeding assembly. After the first swing gripper of the first transfer robot picks up the oil seal, it uses the sensor on the first swing gripper to identify the front and back of the oil seal. If the oil seal is reversed, the first swing gripper is rotated to flip the oil seal over.

[0064] The first swing gripper places the oil seal into the outer ring oiling assembly for outer ring oiling, and then returns to the oil seal feeding assembly. The second swing gripper sends the oil seal into the inner ring oiling assembly for inner ring oiling. The second swing gripper places the oil seal with the inner ring oiling completed into the transfer station, where the vision recognition assembly performs visual recognition of the oil seal oiling.

[0065] The second transfer robot moves the good oil seals from the transfer station to the pressing assembly for the oil seal pressing process, and moves the defective oil seals from the transfer station to the defective product recycling station.

[0066] A more specific implementation method is:

[0067] 1. Manually replace the rotating material tower. The detection component checks for material. During the oil seal feeding process, the module moves upward, driving the oil seal upward. The sensor detects the material.

[0068] 2. The first swing gripper on the transverse component picks up the material from the tower. The laser displacement sensor above the first swing gripper detects the orientation of the oil seal. If the oil seal is reversed, the flip cylinder drives the oil seal to flip 180° and then transversely places it onto the rotating outer ring oiling component.

[0069] 3. Rotating the outer ring oiling component causes the oil seal to flip 90 degrees to the left, and the oil seal completes the outer ring oiling in the oil box. Then it flips 90 degrees to the right to return to its original position. At this time, the first swinging gripper on the transverse component has returned to the feeding component, and the material is picked up.

[0070] 4. The second swinging jaw on the transverse component picks up the oil seal from the outer ring oiling component, flips it, and transversely places it on the inner ring oiling component (the camera component detects the positive and negative directions of the oil seal). At this time, the first swinging jaw places the oil seal on the outer ring oiling component (the two jaws alternately move the material at one time).

[0071] 5. In the inner ring oiling process, the inner ring of the oil seal is oiled through the oil pump assembly and the metering valve.

[0072] 6. After the inner ring is coated with oil, the second swinging jaw will pick up and flip the oil seal on the inner ring coating assembly. Good products will be placed in the transfer position, and defective oil seals will be collected in the defective collection assembly. At the same time, the first swinging jaw will pick up and flip the oil seal on the outer ring coating assembly and move it horizontally to the inner ring coating assembly (the two jaws will move the material alternately again).

[0073] 7. The front and rear transport components move the oil seal from the transfer position to the vicinity of the pressing station to wait. At this time, the operator has already placed the motor at the pressing station. The front and rear components transport the oil seal to the pressing station, and the pressing station automatically presses it.

[0074] 8. After pressing is completed, defective products are placed into the defective product removal conveyor belt. The conveyor belt's sensors detect the material and move it forward, while good products are placed on the carrier plate.

[0075] By applying the layout method of this application, space can be utilized more rationally, integrating oil seal feeding, outer ring oiling, inner ring oiling, defective product detection and pressing into one piece of equipment, improving processing efficiency while reducing the additional costs caused by separate multi-stage processing.

[0076] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
