Description

Technical Field

[0001] The utility model relates to the field of automatic sleeve rings for automobile screws, in particular to an automatic sleeve ring mechanism for automatic assembly equipment of automobile screw foam washers. Background Art

[0002] In the field of automobile manufacturing, some key connection parts (such as stud screws on roof racks and fixing screws for new energy battery boxes) need to have both structural strength and sealing and shock-absorbing functions. Such automobile screws usually need to be fitted with foam washers on the external threaded section to utilize their elastic compression characteristics to achieve waterproofing, shock absorption and stress buffering requirements. Such washers are currently mainly installed manually due to their soft material and small size to ensure their integrity and assembly position accuracy.

[0003] However, the current manual sleeve operation has significant shortcomings: first, manual operation efficiency is low and the process controllability is insufficient. The foam gasket is prone to tearing due to uneven force during the sleeve operation, resulting in deterioration of sealing performance and increased rework rate. Second, the existing automated equipment is limited by the low strength characteristics of the foam material, and it is difficult to achieve stable grasping and precise positioning, resulting in limited yield improvement. In addition, due to the stickiness of the foam gasket, it is inevitable to touch the glue area during manual sleeve operation, resulting in reduced viscosity, affecting the quality of the entire finished product. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide an automatic washer inserting mechanism for an automatic assembly device for automobile screw foam washers in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic gasket-inserting mechanism of an automated assembly equipment for automobile screw foam washers, comprising a workbench, a plurality of screw positioning seats being provided on the workbench, a plurality of positioning holes for accommodating screws being provided on the screw positioning seats, a foam gasket conveying assembly for conveying foam gaskets and a gasket installation assembly for sleeveing ​​the foam gaskets on the foam gasket conveying assembly onto the outside of the screws of the screw positioning seats being provided on one side of the workbench, the gasket installation assembly comprising a manipulator and a foam transfer jig loaded on the manipulator, the foam transfer jig comprising a foam transfer rack arranged at the working end of the manipulator, a plurality of foam absorption cylinders arranged on the foam transfer rack, a plurality of foam vacuum absorption holes being provided on the surface of the foam absorption cylinder, and a screw ring clearance hole being provided in the center of the foam absorption cylinder.

[0006] By adopting the above technical scheme, the workbench can be a turntable or a conveyor belt or other platforms that can be used for subsequent convenient unloading. The automatic gasket sleeve mechanism can be used for fully automated assembly or semi-automated assembly. For example, manual labor is responsible for the loading of screws and the unloading of finished products. The screw positioning seat of the workbench fixes the screw position through the positioning hole. The foam gasket conveying component conveys the foam gasket to the preset station. The manipulator of the gasket installation component drives the foam transfer fixture to move to the foam gasket. The foam absorption cylinder absorbs the foam gasket through the foam vacuum absorption hole set on the surface. During the absorption process, the screw ring in the center of the foam absorption cylinder is used to make way. The hole provides an avoidance space for the screw head. The robot moves the adsorbed foam gasket to the top of the screw positioning seat and puts the foam gasket on the outside of the screw by vertically pressing down. The screw ring clearance hole ensures that there is no mechanical interference in the ring process. The foam vacuum adsorption hole realizes non-contact grasping of the foam gasket to avoid foam tearing or deformation due to mechanical clamping. The structural design of the screw ring clearance hole ensures the precise alignment of the foam gasket and the screw during the ring process to prevent scratching the screw surface. The coordinated action of the robot and the foam transfer fixture realizes automated installation, improves assembly efficiency and finished product qualification rate, and adapts to the large-scale assembly needs of automotive screws.

[0007] Furthermore, the end of the foam adsorption cylinder is provided with a plug-in portion for inserting into the foam gasket, a step adsorption surface is formed between the plug-in portion and the foam adsorption cylinder, the foam vacuum adsorption hole is arranged around the step adsorption surface, and the screw ring clearance hole is arranged on the plug-in portion.

[0008] By adopting the above technical scheme, a plug-in part is provided at the end of the foam adsorption tube, and the outer diameter of the plug-in part is slightly larger than the inner diameter of the center hole of the foam gasket. After being inserted into the center hole of the foam gasket, the step adsorption surface formed between the plug-in part and the main body of the foam adsorption tube generates a uniform adsorption force on the foam gasket through the surrounding foam vacuum adsorption holes. During the adsorption process, the plug-in part radially limits the foam gasket, and the screw ring clearance hole runs through the center of the plug-in part. When the ring is inserted, the head or outer diameter of the screw is avoided to ensure that there is no mechanical interference when the foam gasket is inserted along the axial direction of the screw, avoiding foam tearing or deformation caused by traditional clamping. The surrounding vacuum adsorption holes provide uniform adsorption force to ensure that the foam gasket is not offset or falling off during the transfer process. The structural design of the screw ring clearance hole ensures that the ring action only acts on the foam gasket, avoiding scratches or damage to the adhesive layer caused by contact with the screw surface, thereby improving the assembly yield and the reliability of the automated process.

[0009] Furthermore, a foam pressing plate is provided at one end of the foam transfer rack.

[0010] By adopting the above technical solution, after the robot transfers the foam gasket to the top of the screw positioning seat, the foam pressing plate is pressed down synchronously with the transfer frame, and uniform pressure is applied to the edge of the foam gasket through physical contact to make it fit with the surface of the screw. The planar structure of the pressing plate ensures uniform pressure distribution, avoids local overpressure or non-fitting, eliminates warping or loosening of the foam gasket due to insufficient elasticity or viscosity, ensures that the circumference of the foam gasket is completely in fit with the screw surface, and enhances sealing performance and assembly reliability. Mechanical compression is used instead of manual pressing to avoid deformation or damage of the foam due to uneven force, thereby improving assembly quality and process consistency.

[0011] Furthermore, the foam pressing plate is provided with a plurality of screw pressing holes corresponding one to one with the positioning holes on the screw positioning seat.

[0012] By adopting the above technical solution, the screw pressing clearance holes set on the foam pressing plate correspond one by one to the positioning holes of the screw positioning seat. When the foam pressing plate is pressed down, the screw pressing clearance holes accurately avoid the screw head or outer diameter on the screw positioning seat, so that the pressing effect of the pressing plate is only applied to the edge area of ​​the foam gasket, avoiding mechanical interference with the screw body. The pressing plate applies uniform pressure to the circumference of the foam gasket, eliminating the risk of sealing failure caused by local non-fitting, and improving the assembly reliability and waterproof / shock absorption performance of the foam gasket and the screw.

[0013] Furthermore, the foam gasket conveying assembly includes a foam conveying rack arranged on the frame, a foam roll conveying disk rotatably arranged on the foam conveying rack for mounting the foam roll, a waste collection reel rotatably arranged on the foam conveying rack for recycling the foam base paper, and a foam conveying motor driving the waste collection reel to rotate and rewind. A stripping paper board and an anti-sticking plate are provided at one end of the foam conveying rack away from the foam roll conveying disk, a stripping channel for the foam base paper to pass through is provided between the anti-sticking plate and the stripping paper board, and the foam conveying motor is used to drive the waste collection reel to rotate and rewind, and then deliver the foam gasket after the foam base paper is peeled off to the anti-sticking plate.

[0014] By adopting the above technical scheme, the foam gasket conveying assembly installs the foam roll with the base paper through the foam roll conveying disk, and the foam conveying motor drives the waste collection reel to rotate and reel the base paper. After the base paper is peeled off through the paper peeling channel between the stripping paper board and the anti-sticking plate, the foam gasket is sent to the anti-sticking plate along with the base paper peeling action. The gap design of the paper peeling channel ensures that there is no displacement deviation during the separation process of the base paper and the foam gasket. The low-viscosity surface of the Teflon anti-sticking plate prevents the foam gasket from accidentally sticking. The continuous winding action of the waste collection reel realizes the continuous peeling of the base paper and the automatic feeding of the foam gasket, avoiding inefficiency or foam damage caused by manual peeling. The surface characteristics of the anti-sticking plate prevent the foam gasket from shifting or sticking, adapting to the rhythm requirements of automated assembly, and improving the overall production efficiency and feeding reliability.

[0015] Furthermore, a foam cover plate is provided above the anti-sticking plate, and a foam paper pressing channel for the foam gasket to pass through is formed between the foam cover plate and the anti-sticking plate.

[0016] By adopting the above technical solution, when the foam gasket after peeling off the backing paper moves to the surface of the anti-sticking plate as the backing paper is rolled up, the foam paper pressing channel limits the lateral displacement of the foam gasket through the gap between the upper and lower plates, while allowing it to pass flat along the preset path. The gap design of the foam paper pressing channel ensures that the foam gasket has a stable posture during the transportation process, avoiding grasping failure due to position offset.

[0017] Furthermore, a foam waste discharge assembly is provided directly opposite the foam gasket conveying assembly, and the foam waste discharge assembly includes a foam waste discharge plate arranged opposite to the anti-sticking plate, and a foam waste discharge transverse movement cylinder driving the foam waste discharge plate to approach or move away from the anti-sticking plate, and the foam waste discharge plate is used to bring the foam waste on the anti-sticking plate away from the foam gasket conveying assembly.

[0018] By adopting the above technical scheme, the foam waste discharge component drives the foam waste discharge plate to move horizontally to the surface of the anti-sticking plate through the foam waste discharge transverse movement cylinder. The foam waste discharge plate and the anti-sticking plate are arranged opposite to each other. When the foam waste remains on the anti-sticking plate after the backing paper is peeled off, the waste discharge plate grabs the foam waste through physical contact or adsorption, and then the transverse movement cylinder drives the waste discharge plate away from the anti-sticking plate to transfer the waste to the preset waste collection area. The moving path of the waste discharge plate is separated from the foam gasket feeding path to avoid interfering with the effective foam gasket delivery. The coordinated action of the foam waste discharge plate and the transverse movement cylinder realizes the automatic removal of waste, avoids feeding interruption or foam gasket contamination caused by waste accumulation, reduces the frequency of manual cleaning, and improves the automation degree and operation efficiency of the production line.

[0019] Furthermore, a foam waste discharge lifting cylinder for driving the foam waste discharge transverse movement cylinder to axially lift and lower is provided at one end of the foam waste discharge transverse movement cylinder, and a plurality of waste vacuum adsorption holes and waste locking needles are provided on the bottom surface of the foam waste discharge plate.

[0020] By adopting the above technical scheme, the foam waste discharge transverse movement cylinder is driven by the foam waste discharge lifting cylinder to realize axial lifting and lowering, and the foam waste discharge plate is controlled to vertically approach or move away from the surface of the anti-sticking plate. When the waste discharge plate descends to the anti-sticking plate, the waste vacuum adsorption holes arranged on its bottom surface adsorb the foam waste through negative pressure, and the waste locking needles simultaneously penetrate into the edge of the foam waste to realize physical fixation. After the adsorption and locking are completed, the waste discharge lifting cylinder lifts the waste discharge plate, and the waste discharge transverse movement cylinder drives the waste discharge plate to move horizontally out of the anti-sticking plate area to transfer the waste to the waste collection position. The dual fixing mechanism of the waste vacuum adsorption hole and the locking needle improves the reliability of waste grabbing and prevents the waste from falling off during the transfer process. The coordinated action of the lifting cylinder and the transverse movement cylinder realizes the precise positioning and directional movement of the waste discharge plate to avoid interference with the effective foam gasket.

[0021] Furthermore, a waste collection tank is provided between the foam waste discharge assembly and the foam gasket conveying assembly.

[0022] By adopting the above technical solution, the waste collection trough realizes the centralized storage and automatic cleaning of waste, avoiding the waste from being scattered into the working area and causing equipment pollution or manual cleaning burden.

[0023] Furthermore, a paper peeling traction assembly is provided between the paper peeling channel and the waste collection drum, and the paper peeling traction assembly includes a traction frame arranged on the foam conveying frame, an active traction roller and a driven traction roller rotatably arranged on the traction frame, a power wheel is provided at the output end of the foam conveying motor after passing through the foam conveying frame, a driving wheel is provided at the active traction roller after passing through the foam conveying frame, and a waste collection wheel is provided at the waste collection drum after passing through the foam conveying frame, a traction synchronous belt is wound between the power wheel and the driving wheel, and a waste collection belt is wound between the driving wheel and the waste collection wheel.

[0024] The above technical scheme is adopted, the paper stripping traction component drives the traction synchronous belt through the power wheel of the foam conveying motor, drives the driving wheel of the active traction roller to rotate, the active traction roller and the driven traction roller clamp the bottom paper and pull it through the paper stripping channel, the active wheel is linked to the waste collection wheel of the waste collection reel through the waste collection belt, so that the waste collection reel rotates synchronously with the active traction roller, and the continuous reeling after the bottom paper is stripped off is realized, the clamping force of the traction roller matches the reeling speed of the waste collection reel, ensures that the tension is constant during the bottom paper stripping process, avoids the bottom paper breakage or the foam gasket displacement, the mechanical linkage of the traction synchronous belt and the waste collection belt realizes the synchronous control of the bottom paper stripping and the waste material reeling, and ensures the coordination of the bottom paper stripping action and the foam gasket feeding, the clamping and traction mechanism of the traction roller ensures that the bottom paper passes through the paper stripping channel smoothly, avoids the displacement or damage of the foam gasket due to the uneven pulling of the bottom paper, and the automatic paper stripping and reeling design reduces manual intervention and improves the feeding efficiency of the foam gasket and the stability of system operation.
