As shown in fig. 1 to 10, the automatic rubber ring assembling apparatus of the present embodiment includes: the automatic feeding device comprises a rack 1, and an assembling platform 2, a clamping mechanism 3, an automatic feeding mechanism 4 and a three-dimensional moving platform 5 which are arranged on the rack 1. The frame 1 is mainly used as a supporting part for mounting related parts, the assembling platform 2 is used for placing and positioning a workpiece 6 to be processed with a claw 61, the clamping mechanism 3 is used for clamping or releasing a rubber ring, the automatic feeding mechanism 4 adopts a rubber ring coiled material 40 mode to feed the rubber ring 401 outwards, and the rubber ring 401 is firstly bonded on a base material 402 of the rubber ring coiled material 40 to realize automatic feeding of the rubber ring 401. The specific structural form of each component is explained as follows.

First, the structural configuration of the assembly platform 2.

The assembly platform 2 comprises a support table 21 and a positioning clamping seat 22 arranged on the support table 21, and a positioning groove 23 is arranged on the positioning clamping seat 22. Specifically, the workpiece 6 to be processed is jammed in the positioning groove 23 to position the workpiece 6 to be processed through the positioning groove 23. The positioning clamping seat 22 supports the workpiece 6 to be processed and positions the mounting position of the workpiece 6 to be processed by means of the positioning groove 23, so that accurate positioning and assembling can be conveniently carried out in the later period. In order to improve the universality and meet the assembly requirements of workpieces 6 to be processed with different specifications and sizes, the width of the positioning groove 23 can be adjusted, the adjusting mode can adopt a detachable positioning piece, the positioning grooves 23 with different widths formed on different positioning pieces can meet the assembly requirements of the corresponding workpieces 6 to be processed, and the positioning pieces can be installed on the positioning clamping seat 22 in a screw mode and the like. Preferably, the upper portion of the positioning clamping seat 22 is provided with a fixed clamping block 221 and a sliding clamping block 222 which are oppositely arranged, the sliding clamping block 222 is slidably arranged on the positioning clamping seat 22, and a positioning groove 23 is formed between the fixed clamping block 221 and the sliding clamping block 222. The sliding manner of the sliding clamping block 222 may be a manner that a guide rail is matched with a sliding groove, for example: the bottom of the sliding clamping block 222 is provided with a dovetail groove, and correspondingly, the positioning clamping seat 22 is provided with a dovetail guide rail, so that the sliding clamping block 222 can slide on the positioning clamping seat 22 by matching the dovetail groove and the dovetail guide rail. In addition, in order to realize the sliding adjustment of the sliding clamping block 222, a threaded hole may be formed on the sliding clamping block 222, and correspondingly, a threaded rod arranged transversely is disposed on the positioning clamping seat 22, and the threaded rod is screwed into the threaded hole, so as to adjust the distance between the sliding clamping block 222 and the corresponding fixed clamping block by rotating the threaded rod. Since the clamping jaws 61 of the workpiece 6 to be processed are pressed by the clamping mechanism 3 from above during assembly, in order to prevent the workpiece 6 to be processed from being bent, deformed and even broken, the assembly platform 2 includes the support rod 24, and the support rod 24 is fixed on the support table 21 and located at one side of the positioning clamping seat 22. In practical use, after the workpiece 6 to be processed is placed on the positioning clamping seat 22, the supporting rod 24 will be located below the corresponding clamping jaw 61 of the workpiece 6 to be processed, so as to provide strong support at the position of the clamping jaw 61 of the workpiece 6 to be processed. Preferably, in order to adjust the height of the supporting rod 24, the bottom of the supporting rod 24 is a threaded rod, and correspondingly, a threaded hole (not shown) is formed in the supporting table 21, so that the height of the top of the supporting rod 24 can be adjusted by rotating the supporting rod.

Second, the structure of the gripping mechanism 3 is arranged.

The clamping mechanism 3 comprises a mounting seat 31, an upright rod 32, a spring assembly 33 and a sliding sleeve 34, the mounting seat 31 is mounted on a moving part of the three-dimensional moving platform 5, the upper end of the upright rod 32 is fixed on the mounting seat 31, a plurality of sets of spring assemblies 33 are distributed on the lower end of the upright rod 32 around the axis of the upright rod, each spring assembly 33 comprises an inner spring 331 and an outer spring 332 which are arranged inside and outside, the upper ends of the inner spring 331 and the outer spring 332 are attached together and fixed on the upright rod 32, a protruding structure 330 protruding towards the outside is formed in the middle of the outer spring 332, a clamping space is formed between the lower ends of the inner spring 331 and the outer spring 332, a first air cylinder 311 is arranged on the mounting seat 31, the sliding sleeve 34 is fixed on a piston rod of the first air cylinder 311. Specifically, the rubber ring 401 is usually made of collodion, has soft texture, and needs to maintain the annular structure when the rubber ring 401 is assembled on the claw 61. Therefore, in order to conveniently and reliably clamp the rubber ring 401, a plurality of elastic sheet assemblies 33 in an inner and outer elastic sheet structure are adopted, the plurality of elastic sheet assemblies 33 are distributed around the lower end part of the upright rod 32, the plurality of inner elastic sheets 331 can be inserted into the inner ring of the rubber ring 401, and the plurality of outer elastic sheets 332 surround the outer part of the rubber ring 401. Since the outer spring 332 is further formed with the protrusion 330, the sliding sleeve 34 is driven by the first cylinder 311 to move downward to press the protrusion 330, so that the lower end of the outer spring 332 is close to the inner spring 331. This causes the rubber ring 401 to be sandwiched in front of the inner spring 331 and the outer spring 332. In the process of clamping the rubber ring 401, the rubber ring 401 still keeps a good annular structure, so that the rubber ring can be better sleeved on the clamping jaw 61. Meanwhile, as the rubber ring 401 is clamped by the multiple groups of inner elastic sheets 331 and outer elastic sheets 332, the clamping mechanism 3 can be ensured to provide enough pulling force for the rubber ring 401, so that the rubber ring 401 can be taken down from the substrate 402 by overcoming the adhesive force of the rubber.

The outer spring plate 332 includes a fixing portion 3321 and a tilted portion 3322, the fixing portion 3321 and the upper end of the inner spring plate 331 are attached to each other and fixed on the vertical rod 32, the tilted portion 3322 is tilted downward and outward, a protrusion 330 is formed on the tilted portion 3322, and a clamping space is formed between the lower end of the inner spring plate and the lower end of the tilted portion 3322. Specifically, the outer elastic sheet 332 is fixed to the vertical rod 32 through the fixing portion 3321 and the inner elastic sheet 331, and the specific fixing manner may be welding or screw connection, which is not described herein. In order to enable the outer resilient tab 332 and the sliding sleeve 34 to be well matched to clamp or loosen the rubber ring 401, the outer resilient tab 332 forms a raised portion 3322 raised outward, and a protrusion 330 is formed on the raised portion 3322. Thus, the raised portion 3322 can better cooperate with the sliding sleeve 34 to actuate the outer resilient tab 332. Preferably, in order to better hold the rubber ring 401, the tilted part 3322 is bent to form an inclined piece 33221 and a flat piece 33222, the inclined piece 33221 is connected with the fixed part 3321 and extends downward and obliquely outward, the lower end part of the inclined piece 33221 is provided with an inward flange, and the flat piece 33222 is connected with the inward flange. Specifically, the inner flanges extend toward the corresponding inner elastic sheets 331, so that the straight pieces 33222 are close to the inner elastic sheets 331. The outer elastic sheet 332 is in a free state without being pressed by the sliding sleeve 34, and the straight piece 33222 is arranged in parallel with the inner elastic sheet 331, so that the rubber ring 401 can be accurately clamped between the inner elastic sheet 331 and the straight piece 33222. In addition, the distance between the outer surfaces of the two inner spring pieces 331 arranged oppositely is smaller than the inner hole size of the rubber ring, and the distance between the inner surfaces of the two outer spring pieces 332 arranged oppositely is larger than the outer circumference size of the rubber ring. Specifically, through the above size design, on one hand, the requirement that in the process of clamping the rubber ring 401, the inner elastic sheet 331 can be accurately inserted into the rubber ring 401 can be met, and on the other hand, after the rubber ring 401 is sleeved on the claw 61 and adhered to the surface of the workpiece 6 to be processed, the sliding sleeve 34 moves upwards to release the outer elastic sheet 332, so that the outer elastic sheet 332 can be effectively released from the rubber ring 401, and the clamping mechanism 3 can be effectively and reliably separated from the rubber ring 401.

Further, the rubber ring 401 used in industry has a circular ring structure or a square ring structure. For the rubber ring 401 with a square ring structure, the cross section of the corresponding claw 61 is also square. This results in that when assembling the rubber ring 401, the posture of the rubber ring 401 needs to be adjusted so that the inner ring surface of the rubber ring 401 can be closely fitted to the surfaces of the claws 61. And because the postures of the claws 61 at different positions on the workpiece 6 to be processed are different, when the rubber ring 401 is assembled to the claws 61, the rubber ring 401 needs to be rotated by a certain angle to meet the assembly requirement. For this purpose, the gripping mechanism 3 further includes a base 35, a stepping motor 36 is disposed on the base 35, the mounting seat 31 is fixed on a motor rotating shaft of the stepping motor 36, and the base 35 is mounted on a moving portion of the three-dimensional moving platform 5. Specifically, during actual use operation, for a workpiece 6 to be processed which needs to be assembled, a moving track of the three-dimensional moving platform 5 driving the clamping mechanism 3 is planned in advance, and meanwhile, when the clamping mechanism 3 moves to the claw 61 which needs to rotate and adjust the rubber ring 401 to meet the assembly requirement, the stepping motor 36 is driven to rotate by a required angle to meet the requirement of accurately assembling the rubber ring 401. Therefore, the rubber ring 401 can be automatically assembled by aiming at the clamping jaws 61 with different postures of the same workpiece 6 to be processed, the adaptability of the rubber ring is effectively improved, and the automatic assembly of different types of workpieces 6 to be processed is realized.

Preferably, the claws 61 on the workpiece 6 to be processed are broken or have insufficient height due to poor processing (for example, in the injection molding process of the workpiece 6 to be processed, the claws 61 are not molded due to insufficient injection molding material at the parts of the claws 61). Therefore, the quality of the assembled finished product is ensured in order to automatically recognize the state of the jaws 61. A second cylinder 37 is further disposed on the base 35, and a distance meter 38 is further disposed on a piston rod of the second cylinder 37. Specifically, after the clamping mechanism 3 clamps the rubber ring 401 and moves above the clamping jaw 61, the distance meter 38 is driven by the second air cylinder 37 to move downwards to the bottom, so that the distance from the upper end of the clamping jaw 61 to the distance meter 38 is measured by the distance meter 38, and if the measured distance meets the requirement, the processing quality of the clamping jaw 61 meets the requirement. In this case, the second cylinder 37 is retracted, and the gripping mechanism 3 is moved down by the three-dimensional moving platform 5 to complete the assembly.

And thirdly, aiming at the structural configuration of the automatic feeding mechanism 4.

Automatic feed mechanism 4 includes installing support 41, backup pad 42, two first pinch rollers 43, rubber ring coiled material 40 and drive module 44, and rubber ring coiled material 40 includes substrate 402 and the rubber ring 401 of bonding on substrate 402, is provided with support shaft 411 on installing support 41, and rubber ring coiled material 40 cover is on support shaft 411, and backup pad 42 is fixed on installing support 41, and first pinch roller 43 is rotatable to be installed on installing support 41 and to lean on the top at backup pad 42, the substrate passes the region of compressing tightly that forms between first pinch roller 43 and the backup pad 42, and drive module 44 is used for the drive the substrate removes. Specifically, in order to meet the requirement of automatically supplying the rubber ring 401, the rubber ring roll 40 is adopted, and the rubber ring 401 is adhered to the substrate 402 in advance through a double-sided adhesive tape and is wound into a roll, wherein the substrate 402 can be made of release paper or a film, so that the rubber ring 401 can be easily taken down from the substrate 402. In actual use, the web of rubber rings 40 is mounted on the support shaft 411 of the mounting bracket 41, and the substrate 402 is connected to the drive module 44 after passing through the nip area. The driving module 44 pulls the substrate 402 forward to move the rubber ring 401 to the upper side of the through hole 421. Thus, the gripping mechanism 3 can be moved down to insert the inner spring 331 into the rubber ring 401, and the rubber ring 401 can be gripped and removed from the substrate 402 by the gripping mechanism 33. In addition, in the process of removing the rubber ring 401 from the substrate 402 by the gripping mechanism 3, since the rubber ring 401 taken out is positioned between the two first pressure rollers 43, the substrate 402 can be pressed by the two first pressure rollers 43. Thus, the first pressure roller 43 can ensure that the substrate 402 does not move when the rubber ring 401 is removed from the substrate 402 against the adhesive force. And in the process that the driving module 44 pulls the substrate 402 to move, because the material of the rubber ring 401 is soft, the rubber ring 401 can be extruded and deformed by the first pressing rollers 43, so that the rubber ring 401 can move between the two first pressing rollers 43 by following the substrate 402 to pass through the first pressing rollers 43. The force of the driving module 44 pulling the substrate 402 is large, and when the substrate 402 is pulled to move, the first pressure roller 43 contacting the substrate 402 rotates. In the equipment debugging process, then need adjust the elasticity of first pressure roller 43, when satisfying substrate 402 on the one hand and removing, first pressure roller 43 also can rotate, and on the other hand satisfies that first pressure roller 43 does not rotate when taking off rubber ring 401 in order to guarantee that substrate 402 is motionless.

Wherein, to the expression entity of drive module 44 can adopt the spool that has the power, the spool passes through motor drive and rotates to the base 402 of setting for the length that the spool can be interrupted rolling rubber ring coiled material 40 output, in order to realize pulling base 402 and remove. Preferably, the driving module 44 includes a horizontal cylinder 441, a vertical cylinder 442 and a gear shaping plate 443, the horizontal cylinder 441 is fixed on the mounting bracket 41 and located at the bottom of the supporting plate 42, the vertical cylinder 442 is fixed on a piston rod of the horizontal cylinder 441, the gear shaping plate 443 is fixed on a piston rod of the vertical cylinder 442, a plurality of vertically arranged gear shaping 444 are disposed on the gear shaping plate 443, a strip-shaped hole 421 correspondingly matched with the gear shaping 444 is further disposed on the supporting plate 42, and the strip-shaped hole is located behind the first pressure roller 43 along the forward direction of the substrate 402. Specifically, when the rubber ring roll 40 is first installed on the installation frame 41, the rubber ring 401 at the head position of the substrate 402 needs to be manually torn off to fit the process hole 403 on the substrate 402 over the raised gear 444, and then the substrate 402 is moved by the extension of the horizontal cylinder 441. The fabrication holes 403 are holes formed in the substrate 402 during the process of forming the rubber ring by punching and cutting after the collodion is bonded to the substrate 402. In addition, the stroke of the horizontal cylinder 441 is fixed by designing the stroke of the horizontal cylinder 441 to the length of the base material 402 per one output of the rubber gasket web 40. The vertical cylinder 442 lifts the toothed plate 443 up to allow the toothed plate 444 to be inserted into the process hole 403 to perform the pulling operation of the substrate 402, and then the vertical cylinder 442 and the horizontal cylinder 441 sequentially contract and return to repeat the above-described extending operation to drive the substrate 402 to be pulled out.

In addition, in the process that the substrate 402 is pulled out by the driving module 44, the automatic feeding mechanism 4 further includes a second pressing roller 45, the second pressing roller 45 is rotatably installed on the installation bracket 41 and abuts against the upper side of the supporting plate 42, and the strip-shaped hole is located behind the second pressing roller 45. Specifically, in the process of pulling the substrate 402 to move forward through the driving module 44, the second pressing roller 45 is close to the strip-shaped hole, and can flatten the substrate 402 at the front part of the strip-shaped hole to prevent the substrate 402 from collapsing to the middle due to the pulling force at the process hole 403. For the specific installation manner of the first pressure roller 43 and the second pressure roller 45, the bearing seat 412 may be configured on the installation bracket 41, and the rotating shafts of the first pressure roller 43 and the second pressure roller 45 are installed on the corresponding bearing seats 412. Meanwhile, the first pressing roller 43 and the second pressing roller 45 are usually wrapped with an elastic layer, and the elastic layer can be made of materials such as silica gel.

Based on the rubber ring automatic assembly equipment in the technical scheme, the specific automatic assembly method comprises the following steps: the automatic feeding mechanism automatically outputs the substrate bonded with the rubber ring, and the three-dimensional moving platform moves the clamping mechanism to the position above the rubber ring; the inner elastic sheet in the clamping mechanism is inserted into the inner ring of the rubber ring, the outer elastic sheet in the clamping mechanism is positioned on the outer side of the rubber ring, and then the sliding sleeve moves downwards to enable the outer elastic sheet to be folded towards the inner elastic sheet so as to enable the rubber ring to be clamped between the inner elastic sheet and the outer elastic sheet; and the three-dimensional moving platform moves the clamping mechanism communicated rubber ring to the upper part of the clamping jaws and moves downwards, the clamping jaws are inserted into the space between the inner elastic sheets, and the rubber ring is sleeved outside the clamping jaws and is adhered to the surface of the workpiece to be processed.

Specifically, after a workpiece to be processed is placed on the assembling platform and is positioned and supported by the positioning clamping seat, the driving module in the automatic feeding mechanism pulls the substrate to move, so that the rubber ring moves between the two first pressing rollers; then, the three-dimensional moving platform drives the clamping mechanism to move above the rubber ring. The clamping mechanism moves downwards to enable the inner elastic sheet to be inserted into the rubber ring; then, the sliding sleeve moves downwards to enable the rubber ring to be clamped between the outer elastic sheet and the inner elastic sheet. The three-dimensional moving platform drives the clamping mechanism to move upwards so that the rubber ring is separated from the substrate and clamped out; at the same time, the rubber ring is moved to the position of the corresponding jaw of the workpiece to be processed. The clamping mechanism moves downwards, so that the clamping jaws are inserted into the area between the inner elastic sheets. The cross-sectional dimension of the clamping jaws is larger than that of the interval formed between the inner elastic sheets. Therefore, the inner elastic sheet can be gradually bent outwards in the process that the clamping jaws are inserted into the gaps between the inner elastic sheets, and at the moment, the sliding sleeve synchronously moves upwards to gradually release the outer elastic sheet; the outer elastic sheet moves outwards under the action of the elasticity of the outer elastic sheet so as to prevent the rubber ring from being excessively extruded; and after the rubber ring is sleeved outside the clamping jaw and adhered to the surface of the workpiece to be processed, the sliding sleeve moves upwards and is far away from the protruding structure, so that the outer elastic sheet resets and is far away from the rubber ring, and then the three-dimensional moving platform drives the clamping mechanism to move upwards. At the moment, the rubber ring is bonded on the surface of the workpiece to be processed, so that the rubber ring cannot move upwards continuously along with the inner elastic sheet, and the assembly operation of the rubber ring is completed. The assembling method can meet the assembling requirement of the rubber ring which is made of flexible materials and has an annular structure, can avoid excessive clamping deformation of the rubber ring during clamping and assembling, and finally achieves the purposes of assembling the rubber ring on a workpiece to be processed well and automatically assembling.

Compared with the prior art, the utility model discloses an advantage is with positive effect: the utility model provides an automatic rubber ring assembling device, which fixes the position of a workpiece through an assembling platform to ensure the accurate positioning of the assembling position of the workpiece and provide the guarantee of the position accuracy for the automatic assembling of the rubber ring; the inner and outer elastic sheets arranged in the clamping mechanism can meet the requirement of clamping the rubber ring, so that the rubber ring can be reliably clamped on one hand, and the assembly requirement of a clamping jaw for sleeving the rubber ring on a workpiece can be met on the other hand; and finally, the clamping mechanism is driven to move by the three-dimensional moving platform to automatically complete the assembly of the rubber ring on the workpiece, so that the automatic assembly is completed, the assembly efficiency is improved, and the labor intensity of workers is reduced.
