Description

Technical Field

[0001] This invention relates to processing equipment for automotive seat parts, specifically processing equipment for adjusters. Background Technology

[0002] A car seat adjuster includes a left half and a right half. The left half has a circular first recessed structure with a first toothed structure on its inner wall. The right half has a circular third protrusion with a fifth toothed structure on its outer wall. The fifth toothed structure engages with the first toothed structure. The left half is mounted on the car seat backrest, and the right half is mounted on the car seat body. Manually or electrically adjusting the right half disengages the fifth toothed structure from the first toothed structure, freeing the backrest from being locked to the seat body. The backrest can then rotate relative to the seat body to adjust the tilt angle. Once in the desired position, manually or electrically adjusting the right half resets it, causing the third protrusion to engage with the first recessed structure, and the fifth toothed structure to mesh with the first toothed structure. The backrest can then be locked in place and cannot rotate relative to the seat body.

[0003] When a car is impacted while in motion, the instantaneous impact force causes the seat back to tend to lurch forward or backward. If this instantaneous impact force is large enough, it can cause the first toothed structure to slip relative to the fifth toothed structure, resulting in the seat back actually lurching forward or backward, potentially injuring the driver or passengers. Therefore, the applicant has made improvements to the left half of the seat back.

[0004] The left half includes a first disc-shaped component and a second disc-shaped component. The first disc-shaped component has a first recessed structure on its front side and a circular first protrusion on its back side. The outer wall of the first protrusion has a second toothed structure, and a small circular protrusion is provided on the first protrusion. The first disc-shaped component has a first central hole through which the small circular protrusion passes. The second disc-shaped component has a second recessed structure on its front side and a second protrusion on its back side. The inner wall of the second recessed structure has a third toothed structure, and the outer wall of the second protrusion has a fourth toothed structure. The second disc-shaped component has a second central hole, the diameter of which is larger than the outer diameter of the small circular protrusion.

[0005] The second recessed structure of the second disc-shaped component mates with the first protrusion of the first disc-shaped component. The second toothed structure of the first protrusion and the third toothed structure of the second recessed structure are in a semi-mate state. If the second disc-shaped component is rotated relative to the first disc-shaped component, the movement trajectory of the second disc-shaped component is an irregular ring. The center of the second disc-shaped component does not coincide with the center of the first disc-shaped component and changes with the rotation of the second disc-shaped component. After the second disc-shaped component is assembled with the first disc-shaped component, a pair of crescents and a semicircular ring are assembled between the inner wall of the second central hole and the outer wall of the small circular protrusion. The pair of crescents and the semicircle form a circle around the outer periphery of the small circular protrusion, causing the center of the second disc-shaped component to deviate from the center of the first disc-shaped component. Then, a limiting component is fitted in the first central hole. The limiting component includes a central portion and a radially extending portion. The central portion fits in the first central hole, and the radially extending portion presses on the pair of crescents and the semicircular ring, limiting them between the inner wall of the second central hole and the outer wall of the small circular protrusion.

[0006] The center part of the limiting component has an internal hexagonal hole, and the external hexagonal pin fits into the internal hexagonal hole. The external hexagonal pin is fixedly connected to the back of the car seat.

[0007] The outer edge of the second disc-shaped component is fitted with a welding ring, which is welded to the first disc-shaped component. Due to the restriction of the welding ring on the outer edge of the second disc-shaped component, the second disc-shaped component and the first disc-shaped component cannot undergo axial relative displacement when fitted together. However, the degree of freedom of rotation of the second disc-shaped component relative to the first disc-shaped component is not restricted by the welding ring. Because a pair of crescents and a semi-circular ring fill the space between the second central hole wall and the small circular protrusion, the second disc-shaped component cannot rotate relative to the first disc-shaped component. During normal use of the angle adjuster, the first and second disc-shaped components will not have any relative movement, acting as if they were a single part.

[0008] When a car is impacted while in motion, the instantaneous impact force causes the backrest to tend to lurch forward or backward. If this instantaneous impact force is large enough, before the first toothed structure slips relative to the fifth toothed structure, the first disc-shaped component will rotate relative to the second disc-shaped component. This irregular rotation causes the semi-circular ring to break due to the compression of the pair of crescents and the wall of the second central hole. The second disc-shaped component then rotates relative to the first disc-shaped component. This rotation is also irregular, and due to the restriction of the pair of crescents, the angle of rotation is small. The second toothed structure of the first disc-shaped component partially engages with the third toothed structure of the second disc-shaped component, resulting in a locked state between the first and second disc-shaped components, preventing further forward or backward lurch of the backrest. Therefore, the angle adjuster, especially the left half, has the ability to mitigate or resist impact, thus protecting the driver or passenger.

[0009] When the welding ring is welded to the first disc-shaped part, the pair of crescents and the semicircular ring are not yet assembled between the second central hole wall and the small circular protrusion. Therefore, it is necessary to protect the space between the second central hole wall and the small circular protrusion to prevent welding slag from entering. To this end, the applicant pre-assembles a pair of crescents and a semicircular ring in the space between the second central hole wall and the small circular protrusion. After assembling the limiting component, a ring spring (shaped similarly to the metal ring on Sun Wukong's head) is used to engage with the pair of crescents at both ends, causing the pair of crescents to tend to move away from each other. In this way, the pair of crescents are locked in the space between the second central hole wall and the small circular protrusion, and the semicircular ring is tightened. In subsequent processes, the ring spring, the pair of crescents, the semicircular ring, and the limiting component are removed, and a new pair of crescents, the semicircular ring, the limiting component, and the ring spring are reassembled.

[0010] For subsequent welding to the liner, the second disc-shaped component has three arc-shaped protrusions on its second protrusion. The three arc-shaped protrusions are located on the same circle, with a gap between adjacent arc-shaped protrusions. The liner is connected to the backrest of the car seat. Summary of the Invention

[0011] The technical problem solved by this invention is: how to conveniently assemble a pair of crescents, a semicircular ring, a limiting member, and a ring spring (collectively referred to as anti-slag assembly) into the space between the second central hole wall and the small circular protrusion before the welding ring is welded to the first disc-shaped part; and how to inject oil and unload the product after assembly.

[0012] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an anti-welding slag assembly and welding ring assembly equipment, including an anti-welding slag assembly unit, a feeding unit, and an oil injection unit. The anti-welding slag assembly unit is located at the right end of the main guide rail, and the feeding unit and the oil injection unit are located at the left end of the main guide rail. The anti-welding slag assembly unit includes a movable seat that fits on a first guide rail, a first product fixture that fits on a second guide rail, and a fixedly installed spring assembly. The movable seat and the spring assembly are located on the front and rear sides of the first product fixture. The movable seat is provided with a push block, which can push the product toward the spring assembly. The front end of the push block is provided with a tongue, which can press the ring spring down onto the product. The spring assembly is provided with a limiting member slot and a semi-circular slot, with the semi-circular slot located inside the limiting member slot.

[0013] Before welding the welding ring to the first disc-shaped component, the first and second disc-shaped components, which are assembled together, are positioned on the first product fixture. First, a pair of crescent-shaped parts and a semi-circular ring are manually installed into the space between the second central hole wall and the small circular protrusion. Then, a limiting member is installed in the first central hole of the first disc-shaped component, with its radially extended portion pressing against the pair of crescent-shaped parts and the semi-circular ring, confining them within the space between the second central hole wall and the small circular protrusion. Next, a ring spring is placed on the radially extended portion of the limiting member; however, the two ends of the ring spring opening are not installed into the space between the second central hole wall and the small circular protrusion. Then, the movable seat is manually pushed, displacing it towards the product. The pusher acts on the side wall of the product, and the tongue presses against the ring spring. Continuing to push the movable seat, the pusher pushes the first product fixture and the product on it towards the spring assembly. The limiting member of the spring assembly engages with both sides of the radially extended portion of the limiting member, and the semi-circular opening engages with the two ends of the ring spring opening. Due to the relative displacement between the product and the semi-circular latch, the semi-circular latch causes the two ends of the ring spring to close, accumulating elastic potential energy. Under the pressure of the tongue, the closed ends of the ring spring are engaged in the space between the second central hole wall and the small circular protrusion. When the first product fixture and the product on it retract and reset, the two ends of the ring spring leave the semi-circular latch, releasing their elastic potential energy. The two ends of the ring spring are then engaged between a pair of crescent-shaped protrusions, which hold the semi-circular ring tightly within the space between the second central hole wall and the small circular protrusion. Thus, the pair of crescent-shaped protrusions, the semi-circular ring, the limiting component, and the ring spring are all fixed in place.

[0014] Next, the welding ring is manually assembled onto the product, meaning the welding ring covers the edge of the second disc-shaped component and contacts the edge of the first disc-shaped component. After this work is completed, the product is moved to the oiling unit and the unloading unit. The oiling unit applies oil to the product, and after completion, the unloading unit unloads the product.

[0015] The anti-weld slag assembly unit of the present invention can conveniently assemble the anti-weld slag assembly, especially the annular spring, into the space between the second central hole wall and the small circular protrusion. The main guide rail can facilitate the transfer of the product from the anti-weld slag assembly unit to the unloading unit and the oiling unit, with the oiling and unloading of the product being completed by the oiling unit and the unloading unit, respectively.

[0033] like Figures 2 to 4The anti-slag component and welding ring assembly equipment includes an anti-slag component assembly unit 10. The anti-slag component assembly unit includes a movable seat 11 that is fitted on a first guide rail 112, a first product fixture 12 that is fitted on a second guide rail 121, and a fixedly installed spring assembly 13. The movable seat and the spring assembly are located on the front and rear sides of the first product fixture. The movable seat is provided with a push block 113, which can push the product toward the spring assembly. The front end of the push block is provided with a tongue 114, which can press the ring spring down onto the product. The spring assembly is provided with a limiting member slot 131 and a semi-circular slot 132, with the semi-circular slot located inside the limiting member slot.

[0034] Before welding the welding ring to the first disc-shaped component, the worker positions the assembled first and second disc-shaped components on the first product fixture 12. The worker first assembles a pair of crescent-shaped parts and a semi-circular ring into the space between the second central hole wall and the small circular protrusion. Then, the worker assembles a limiting member into the first central hole of the first disc-shaped component, with the radially extended portion of the limiting member pressing against the pair of crescent-shaped parts and the semi-circular ring, confining them within the space between the second central hole wall and the small circular protrusion. Next, the worker places a ring spring on the radially extended portion of the limiting member; however, the two ends of the ring spring opening are not assembled into the space between the second central hole wall and the small circular protrusion. Then, the worker pushes the movable seat 11, which moves towards the first product fixture 12. The pusher 113 acts on the side wall of the product on the first product fixture 12, and the tongue 114 presses against the ring spring. The worker continues to push the movable seat 11, and the pusher 113 pushes the first product fixture 12 and the product on it towards the spring assembly 13. The limiting member 131 of the spring assembly engages with both sides of the radially extended portion of the limiting member, and the semi-circular locking member 132 engages with the two ends of the opening of the annular spring. Due to the relative displacement between the product and the semi-circular locking member 132, the semi-circular locking member causes the two ends of the opening of the annular spring to close, and the annular spring accumulates elastic potential energy. Under the pressure of the tongue 114, the two ends of the closed annular spring are inserted into the space between the second central hole wall and the small circular protrusion. The first product fixture 12 and the product on it retract and reset, the two ends of the annular spring leave the semi-circular locking member 132, the annular spring releases its elastic potential energy, and the two ends of the annular spring are locked between a pair of crescents, which hold the semi-circular ring tightly within the space between the second central hole wall and the small circular protrusion. In this way, the pair of crescents, the semi-circular ring, the limiting member, and the annular spring are all fixed.

[0035] The second guide rail 121 is mounted on the second guide rail plate 122, and the second guide rail plate is provided with a return spring 123 connected to the first product fixture 12. When the first product fixture 12 moves toward the spring assembly 13, the return spring 123 is stretched, accumulating elastic potential energy. After the push block 113 releases the first product fixture 12 and the product on it, the return spring 123 pulls the first product fixture 12 back to its original position.

[0036] The first guide rail plate 116, the second guide rail plate 122, and the spring assembly 13 are mounted on the same anti-welding slag assembly unit base plate 14.

[0037] like Figure 5 A pressing rod 133 is movably fitted onto the spring assembly 13, and a telescopic spring 134 is provided on the pressing rod. The front end of the pressing rod can abut against the product on the first product fixture 12. In this way, the front side of the product is pressed by the push block 113, and the rear side of the product is pressed by the pressing rod 133, so that the product is in a stable state, which provides favorable conditions for the annular spring to be assembled into the space between the second central hole wall and the small circular protrusion.

[0038] The anti-slag assembly unit 10 is located at the right end of the main guide rail 20. A feeding unit 30 and an oil injection unit 40 are located at the left end of the main guide rail. A second product fixture 21 is mounted on the main guide rail, and a welding ring assembly station 22 is located in the middle of the main guide rail. After the anti-slag assembly is completed, the worker removes the product from the first product fixture 12 and places it on the second product fixture 21. The second product fixture 21 is then moved to the welding ring assembly station 22, where the worker assembles the welding ring onto the product, i.e., the welding ring covers the edge of the second disc-shaped component and contacts the edge of the first disc-shaped component. After this work is completed, the worker moves the second product fixture 21 and the product on it to the oil injection unit 40 and the feeding unit 30. The oil injection unit 40 injects oil into the product, and after completion, the feeding unit 30 feeds the product.

[0039] like Figure 6 The oil injection unit 40 includes an oil injection unit base 41, an oil injection unit guide column 42 disposed on the oil injection unit base, an oil injection lifting module 43 cooperating with the oil injection unit guide column, and an oil injection nozzle 44 disposed on the oil injection lifting module. An oil injection unit cylinder 45 is provided on the oil injection unit base, and the piston rod of the oil injection unit cylinder is connected to the oil injection lifting module.

[0040] The oil injection unit cylinder 45 drives the oil injection lifting module 43 to descend along the oil injection unit guide column 42 to above the product on the second product fixture 21, and the oil injection nozzle 44 injects oil into the corresponding parts of the product. After completion, the oil injection lifting module 43 rises and resets, and the unloading unit 30 unloads the product.

[0041] Combination Figure 2 , Figure 7The unloading unit 30 includes a translation cylinder 31, a translation plate 32 connected to the translation cylinder, a first lifting cylinder 33 disposed on the translation plate, and a gripper cylinder 34 disposed on the first lifting cylinder. The gripper cylinder can transfer the product on the second product fixture 21 to the inclined conveyor plate 35.

[0042] After the oil filling lifting module 43 rises and resets, the translation cylinder 31 drives the translation plate 32 to move above the second product fixture 21. The first lifting cylinder 33 descends, and the gripper cylinder 34 opens, then grips the product. Driven by the translation cylinder 31, the gripper cylinder 34 moves the product above the inclined conveyor plate 35. Then, the first lifting cylinder 33 drives the gripper cylinder 34 to descend, the pair of grippers of the gripper cylinder 34 open, and the product falls above the inclined conveyor plate 35, from which the product is output.

[0043] As an improvement, the inclined conveyor plate 35 has a through hole 350, and a buffer block 36 is provided below the through hole. The buffer block is fitted on the buffer seat 361, which is installed on the piston rod of the second lifting cylinder 362. A buffer spring is provided between the buffer block and the buffer seat.

[0044] The second lifting cylinder 362 drives the buffer seat 361 and buffer block 36 to rise, with the buffer block protruding upward through the through hole 350 and onto the inclined conveyor plate 35. Then, the first lifting cylinder 33 descends, placing the product onto the buffer block 36. After the gripper cylinder 34 releases the product, the second lifting cylinder 362 drives the buffer seat 361 and buffer block 36 to descend and reset, allowing the product to fall smoothly onto the inclined conveyor plate 35. The design of the buffer block 36 effectively avoids any impact that may occur when the product falls onto the inclined conveyor plate 35.

[0045] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
