Description

Technical Field

[0001] The invention relates to the technical field of oil seal production, and in particular to an automatic assembly production line for oil seals. Background Art

[0002] Assembled oil seal is a special type of oil seal, the main feature of which is that its frame and lip materials can be freely combined. This design makes assembled oil seals suitable for more special working environments and application requirements. For example, in certain working environments with high temperature, high pressure or corrosive media, high temperature resistant, high pressure resistant or corrosion resistant frame and lip materials can be selected to ensure the sealing performance and durability of the oil seal.

[0003] When processing the assembled oil seal, the formed lip part needs to be bonded to the frame. When bonding, a layer of adhesive is usually applied on the contact surface of the two, and then the two are connected;

[0004] However, in actual application, due to the high precision required for assembled oil seals, it is necessary to ensure the accuracy of the bonding between the lip and the frame. In the prior art, the lip and the frame are usually docked first, and then the detection equipment is used to detect whether the two are accurately docked. If there is a docking deviation, adjustment equipment or manual adjustment is used, which is more cumbersome. In addition, the position adjustment of the two after bonding will also reduce the bonding effect of the adhesive. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1 As shown, the present invention is an automatic assembly production line for oil seals, comprising a loading part 1, an assembly module and a unloading part 3 arranged in sequence;

[0038] The loading part 1 is used to transport the skeleton body 5 and the lip body 501 to be assembled toward the assembly module;

[0039] The assembly module is used to assemble the delivered skeleton body 5 and the lip body 501;

[0040] The unloading part 3 is used to output the assembled oil seal to the next process; in this embodiment, the loading part 1 includes a loading conveyor belt and a loading robot 101, and the unloading part 3 includes a unloading conveyor belt and a unloading robot 301; specifically, in this embodiment, the skeleton body 5 and the lip body 501 to be assembled are first arranged on the loading conveyor belt and conveyed in the direction of the assembly module. When conveyed to the loading end, the skeleton body 5 or the lip body 501 is transferred to the assembly module for assembly by the loading robot 101. After the assembly is completed, the oil seal is transferred to the unloading end on the unloading conveyor belt by the unloading robot 301, and finally output to the next processing process through the unloading conveyor belt. This embodiment does not require manual loading, assembly and unloading, and has a higher degree of automation.

[0041] See also Figure 5 It should be noted that, since both the skeleton body 5 and the lip body 501 are annular structures, the grabbing end of the loading robot 101 of this embodiment is fixedly provided with a ring body 102, and a number of adsorption ends 103 for adsorbing the skeleton body 5 and the lip body 501 are fixedly provided in a circumferential array on the ring body 102, and the adsorption ends 103 are connected to the negative pressure generator; specifically, since the lip body 501 is usually made of flexible or elastic material, this embodiment adopts negative pressure adsorption to grasp the skeleton body 5 and the lip body 501, which has higher stability.

[0042] See also Figure 2-Figure 3 The assembly module includes a positioning platform 2, on which a turntable 201 is rotatably arranged, and on which a positioning mechanism for positioning the skeleton body 5 and the lip body 501 is arranged. The assembly module also includes a glue coating structure and a docking mechanism. The glue coating structure is used to apply adhesive to the contact surface of the skeleton body 5 and the lip body 501, and the docking mechanism is used to drive the skeleton body 5 and the lip body 501 to bond;

[0043] It can be explained that, in this embodiment, the skeleton body 5 and the lip body 501 to be assembled are first positioned in sequence by a positioning mechanism. After the positioning is completed, the adhesive is coated on the contact surface of the skeleton body 5 and the lip body 501 by a glue coating structure. After the coating is completed, the skeleton body 5 and the lip body 501 are driven close to each other and bonded by a docking mechanism. In this embodiment, a positioning mechanism is set to pre-position the skeleton body 5 and the lip body 501 before bonding, so that the two can always maintain a coaxial state when docking, thereby achieving the effect of precise docking and avoiding the occurrence of offset or misalignment.

[0044] Example 2

[0045] Based on Example 1, please refer to Figure 2-Figure 4The positioning module includes several groups of positioning seats 609 arranged in a circumferential array on the turntable 201, and each group of positioning seats 609 is connected to a driving part that drives it to move closer to or away from the axial direction of the turntable 201; specifically, three groups of positioning seats 609 are arranged in this embodiment; it can be explained that before assembling the skeleton body 5 and the lip body 501, the skeleton body 5 and the lip body 501 are firstly sleeved on the outside of the three groups of positioning seats 609, and then the three groups of positioning seats 609 are driven by the driving part to move synchronously in the direction away from the axis, so that the positioning seats 609 are abutted against the inner edges of the skeleton body 5 and the lip body 501, thereby achieving the effect of positioning the skeleton body 5 and the lip body 501.

[0046] In this embodiment, the driving part includes a positioning plate 603 fixedly arranged on the turntable 201, and a plurality of positioning plates 604 are fixedly arranged in a circumferential array on the outer edge of the positioning plate 603, and a guide groove 605 is provided on the positioning plate 604, and a pin shaft 608 fixed to the positioning seat 609 is slidably arranged in the guide groove 605, wherein a turntable 402 is also rotatably arranged on the turntable 201, and a plurality of arc grooves 407 are provided in a circumferential array on the turntable 402, and the arc groove 407 extends from the near center end to the far center end, and the bottom end of the pin shaft 608 is slidably embedded in the arc groove 407, and a first gear ring 403 is fixedly arranged on the outer edge of the turntable 402, and the turntable A first motor 4 is fixedly arranged on one side of the bottom of 201, and a first gear 401 meshing with a first gear ring 403 is fixedly arranged on the output end of the first motor 4; it can be explained that in this embodiment, the first motor 4 drives the first gear 401 to rotate, and the first gear 401 drives the turntable 402 to rotate by meshing with the first gear ring 403. Based on the setting of the arc groove 407, the pin shaft 608 can move linearly along the guide groove 605. Since the three groups of arc grooves 407 have the same structure and are arranged circumferentially, the pin shafts 608 can move synchronously, and the positioning seat 609 can be driven to move synchronously during the movement of the pin shaft 608.

[0047] As a further solution of this embodiment, please refer to Figure 2-Figure 4 , a positioning rod 606 is fixedly arranged on one end of the positioning plate 604 away from the positioning disk 603, and the end of each group of positioning rods 606 is fixed to the positioning ring 607; specifically, in this embodiment, the skeleton body 5 is first transferred to the positioning ring 607 through the loading robot 101 to support the skeleton body 5.

[0048] See also Figure 4 as well as Figure 6-Figure 8The docking mechanism includes a lifting cylinder 7 fixedly arranged on the positioning plate 603, the driving end of the lifting cylinder 7 is fixed to the lifting plate 701, and the outer edge surface of the lifting plate 701 is fixedly arranged with three groups of bearing rods 702 in a circumferential array, and the other end of the bearing rod 702 is slidably connected to the wedge frame 704, and an inclined surface 707 is arranged on the side of the bottom of each wedge frame 704 away from the axis, wherein a telescopic spring 703 is arranged on the bearing rod 702; specifically, one end of the telescopic spring 703 is fixed to the wedge frame 704, and the other end is fixed to the lifting plate 701;

[0049] It can be explained that, in the initial state, the distance between the end of each wedge frame 704 and the axis is greater than the inner diameter of the skeleton body 5 and the lip body 501 but smaller than the outer diameter of the skeleton body 5 and the lip body 501. Therefore, the loading robot 101 first places the skeleton body 5 on the wedge frame 704 for support, and then drives the lifting plate 701 to descend through the lifting cylinder 7. Figure 7-Figure 8 When the lifting plate 701 is lowered to a certain height, the inclined surface 707 first contacts with the ring body of the positioning ring 607. As the lifting plate 701 continues to descend, each wedge frame 704 can synchronously move along the bearing rod 702 toward the axis to compress the telescopic spring 703. When the wedge frame 704 is retracted to its end contacting with the inner wall of the positioning ring 607, the skeleton body 5 is transferred to the positioning ring 607. Then, the lifting cylinder 7 drives the lifting plate 701 to reset to the initial position, and then the lip body 501 to be bonded is placed on the wedge frame 704 by the loading robot 101, and then the three groups of positioning seats 60 are driven by the driving unit. 9 synchronously moves in a direction away from the axis so that the positioning seat 609 abuts against the inner edge surface of the skeleton body 5 and the lip body 501, thereby realizing the positioning of the skeleton body 5 and the lip body 501, so that the skeleton body 5 and the lip body 501 are coaxial. After the positioning is completed, the driving unit drives the three groups of positioning seats 609 to move synchronously in a direction close to the axis so that the positioning seat 609 is separated from the skeleton body 5 and the lip body 501. After the adhesive is coated on the surface of the skeleton body 5, the lip body 501 is placed on the skeleton body 5. In this embodiment, the placement process of the lip body 501 is the same as the placement process and principle of the skeleton body 5.

[0050] It should also be noted that when the loading robot 101 places the skeleton body 5 and the lip body 501, even if the two are not in a coaxial state when placed, this embodiment can also synchronously coaxially position the skeleton body 5 and the lip body 501 by setting a positioning seat 609 to improve the subsequent docking accuracy.

[0051] Furthermore, each wedge-shaped frame 704 is provided with a rotatable guide wheel 706 at one end away from the axis. Specifically, by providing the guide wheel 706 at the end of the wedge-shaped frame 704, the friction between the wedge-shaped frame 704 and the skeleton body 5 and the lip body 501 can be reduced during the rising process. On the one hand, the skeleton body 5 and the lip body 501 can be protected, and on the other hand, the skeleton body 5 and the lip body 501 can be prevented from being lifted up when the wedge-shaped frame 704 rises.

[0052] It should also be noted that the oil seal in this embodiment is not limited to being assembled into one set of lip bodies 501, but two or three sets may also be provided, and there is no limitation on the number.

[0053] In addition, guide rods 705 are fixedly arranged on each positioning plate 604 , and the lifting plate 701 is slidably connected to the guide rods 705 to improve the stability of the movement of the lifting plate 701 .

[0054] In this embodiment, after the oil seal is assembled, the unloading robot 301 adsorbs and fixes the oil seal, and drives the adsorbed oil seal to be transferred to the unloading conveyor belt.

[0055] See also Figure 2-Figure 4 The glue coating structure includes a lifting mechanism 404 fixedly arranged on one side of the positioning platform 2, a lifting plate 405 is fixedly arranged on the lifting end of the lifting mechanism 404, a horizontal cylinder 406 is fixedly arranged on the lifting plate 405, a driving end of the horizontal cylinder 406 is fixed to the pump body 6, the bottom end of the pump body 6 is connected to the glue discharge terminal 602, and the pump body 6 is connected to the outer glue storage box through the glue delivery pipe 601; it can be explained that when coating the glue, the pump body 6 is started, and the pump body 6 extracts the adhesive in the outer glue storage box through the glue delivery pipe 601 and transports it to the glue discharge terminal 602, and finally discharges it to the surface of the skeleton body 5 or the lip body 501 through the glue discharge terminal 602.

[0056] Correspondingly, this embodiment can adjust the position of the glue removal end 602 by setting up a lifting mechanism 404 and a horizontal cylinder 406. For example, when the skeleton body 5 is placed, the horizontal cylinder 406 can drive the glue removal end 602 to move in a direction away from the axis of the turntable 201 to avoid motion interference. At the same time, when the skeleton body 5 and the lip body 501 are docked, their positions also need to be adjusted.

[0057] The lifting mechanism 404 in this embodiment may adopt a screw and nut transmission mechanism or a synchronous belt transmission mechanism, which is not limited in this embodiment.

[0058] See also Figure 2-Figure 3A second gear ring 202 is fixedly arranged on the outer edge surface of the turntable 201, a second motor 204 is fixedly arranged on one side of the positioning platform 2, and a second gear 203 meshing with the second gear ring 202 is fixedly arranged on the output end of the second motor 204; specifically, when gluing the skeleton body 5 and the lip body 501, the second motor 204 is started synchronously, and the second motor 204 can drive the turntable 201 to rotate through the second gear 203, so as to realize circumferential gluing treatment of the skeleton body 5 and the lip body 501.

[0059] An assembly method for an oil seal automatic assembly production line comprises the following steps:

[0060] See also Figure 1-Figure 4 , arranging the skeleton body 5 and the lip body 501 to be assembled on the feeding conveyor belt and conveying them in the direction of the assembly module;

[0061] The loading robot 101 first places the skeleton body 5 on the wedge frame 704 for support, and then drives the lifting plate 701 to descend through the lifting cylinder 7;

[0062] See also Figure 4 as well as Figure 6-Figure 8 After the lifting plate 701 is lowered to a certain height, the inclined surface 707 first contacts the ring body of the positioning ring 607. As the lifting plate 701 continues to descend, each wedge frame 704 can synchronously move toward the axis along the bearing rod 702. When the wedge frame 704 is retracted until its end contacts the inner wall of the positioning ring 607, the skeleton body 5 is transferred to the positioning ring 607.

[0063] The lifting cylinder 7 drives the lifting plate 701 to return to the initial position, and the loading robot 101 places the lip body 501 to be bonded on the wedge frame 704;

[0064] The driving unit drives the three groups of positioning seats 609 to move synchronously in a direction away from the axis, so that the positioning seats 609 abut against the inner edges of the skeleton body 5 and the lip body 501, thereby achieving the positioning of the skeleton body 5 and the lip body 501;

[0065] The driving unit drives the three groups of positioning seats 609 to move synchronously toward the direction close to the axis, so that the positioning seats 609 are separated from the skeleton body 5 and the lip body 501. After the surface of the skeleton body 5 is coated with adhesive, the lip body 501 is placed on the skeleton body 5;

[0066] After the oil seal is assembled, the unloading robot 301 adsorbs and fixes the oil seal, and drives the adsorbed oil seal to be transferred to the unloading conveyor belt.
