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] After the first and second disc-shaped components are assembled together, oil needs to be injected into the first toothed structure of the first disc-shaped component and the second toothed structure of the second disc-shaped component. The oiling direction is generally from top to bottom, with the oiling mechanism located above the product. After the first disc-shaped component is oiled, a flipping mechanism is needed to flip the product so that the oiling mechanism can then inject oil into the second disc-shaped component. However, this process causes the oil on the first disc-shaped component to flow along the product or drip, affecting the oiling effect and contaminating the production equipment.

[0012] The technical problem solved by this invention is: for products that require oiling on both the top and bottom, how to avoid or reduce oil flow or dripping after oiling is completed on one side and the product is flipped over.

[0013] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a product oil injection and feeding mechanism, including an oil injection mechanism and a feeding mechanism. The oil injection mechanism is located above the feeding mechanism. The oil injection mechanism includes an oil injection head that is driven to rise and fall by an oil injection lifting cylinder. The feeding mechanism includes a tilting mechanism and a feeding plate. The tilting mechanism is located above one end of the feeding plate. The oil injection head and the oil injection lifting cylinder are arranged on a horizontal moving plate. A wind duct is also provided on the horizontal moving plate. The horizontal moving plate is movably fitted on a fixed plate. The horizontal moving plate is connected to a horizontal moving cylinder. A cold air fan is provided on the fixed plate. The cold air fan is located above the wind duct and the oil injection head.

[0014] The flipping mechanism clamps the product, and the oil injection lifting cylinder drives the oil injection head to descend, injecting oil into the first toothed structure of the first disc-shaped component. Afterwards, the oil injection head rises and resets, and the lateral movement cylinder drives the lateral movement plate to move laterally, moving the oil injection head away from directly above the product, while the air duct moves directly above the product and below the air outlet of the cooler. The cooler blows air, cooling the oil on the product through the air duct; at low temperatures, the oil's fluidity decreases. Simultaneously, under air pressure, the oil at each injection point can diffuse to the surrounding area, achieving a comprehensive oiling effect. Then, driven by the lateral movement cylinder, the air duct moves away from directly above the product, and the oil injection head moves directly above the product. The flipping mechanism flips the product, and the oil injection head injects oil into the second toothed structure of the second disc-shaped component. After completion, the oil injection head rises and resets. Then, driven by the lateral movement cylinder, the air duct moves directly above the product, and the cooler cools the oil on the product. Finally, the flipping mechanism moves the product to the unloading plate, which unloads the product.

[0015] This invention uses a cold air blower to cool the oil after the product is filled with oil, which makes the oil filling more uniform and reduces the fluidity of the oil, preventing the oil from flowing along the product or dripping, thus improving the oil filling effect. Moreover, it can prevent the oil from contaminating production equipment, such as the turning mechanism, the feeding plate, and the equipment for subsequent product assembly.

[0028] like Figure 1 An oil injection and feeding mechanism for a product includes an oil injection mechanism 10 and a feeding mechanism 30. The oil injection mechanism is located above the feeding mechanism. The oil injection mechanism includes an oil injection head 12 that is driven to rise and fall by an oil injection lifting cylinder 11. The feeding mechanism includes a tilting mechanism 31 and a feeding plate 32. The tilting mechanism is located above one end of the feeding plate. The oil injection head and the oil injection lifting cylinder are mounted on a transverse plate 13. A duct 14 is also mounted on the transverse plate. The transverse plate is movably fitted onto a fixed plate 15. The transverse plate is connected to a transverse cylinder 16. A cool air blower 17 is mounted on the fixed plate. The cool air blower is located above the duct and the oil injection head.

[0029] The flipping mechanism 31 clamps the product, and the oil injection lifting cylinder 11 drives the oil injection head 12 to descend, injecting oil into the first toothed structure of the first disc-shaped part. Afterwards, the oil injection head 12 rises to its original position, and the lateral movement cylinder 16 drives the lateral movement plate 13 to move laterally, moving the oil injection head 12 away from directly above the product. Meanwhile, the air duct 14 moves directly above the product and below the air outlet 170 of the cooler 17. The cooler 17 blows air, cooling the oil on the product through the air duct 14. At low temperatures, the oil's fluidity decreases. Simultaneously, under air pressure, the oil at each injection point can diffuse to the surrounding area, achieving a comprehensive oiling effect.

[0030] Then, driven by the lateral movement cylinder 16, the air duct 14 moves away from directly above the product while the oil injection head 12 moves to directly above the product. The flipping mechanism 31 flips the product, and the oil injection head 12 injects oil into the second toothed structure of the second disc-shaped part. After completion, the oil injection head 12 rises and resets. Then, driven by the lateral movement cylinder 16, the air duct 14 moves to directly above the product, and the cooler 17 cools the product oil. Then, the flipping mechanism 31 moves the product to the unloading plate 32, and the unloading plate unloads the product.

[0031] like Figure 5The air duct 14 includes an outer shell 141 and an inner shell 142. The outer shell is open at both the top and bottom, forming a through-type structure. The inner shell 142, in addition to being open at both the top and bottom, lacks a side wall, meaning the inner shell 142 is U-shaped overall. A cylinder 143 for the air duct is located at the top of the outer shell, and the piston rod of this cylinder is connected to the top of the inner shell. When air needs to be blown onto the product, the air duct 14 moves directly above the product. Then, the cylinder 143 drives the inner shell 142 to descend, covering the product. Cold air from the cooler 17 is then pumped onto the product through the outer shell 141 and the inner shell 142. This improves the cooling effect on the oil on the product. The U-shaped inner shell 142 avoids the tilting mechanism 31, meaning it can cover the product while avoiding the tilting mechanism 31. After the inner shell 142 rises into the outer shell 141, the entire air duct 14 moves horizontally, moving away from directly above the product.

[0032] like Figure 3 The outer casing 141 has ventilation holes 144 on its side wall. The air outlet 170 of the air cooler 17 points vertically downward, directing cold air towards the product. The presence of ventilation holes 144 does not affect the delivery of cold air to the product. The function of ventilation holes 144 is twofold: first, to prevent the formation of high pressure inside the air duct 14; second, as the cold air rushes towards the product and surrounding equipment, dust on the product or surrounding equipment will rise into the air duct 14 and flow back into the air cooler 17, potentially damaging the air cooler; dust accumulated inside the air duct will be blown towards the product and adhere to the oil. Under the action of airflow, ventilation holes 144 can expel dust from the air duct 14.

[0033] Combination Figure 6 , Figure 7 The flipping mechanism 31 includes a pair of grippers 312 connected to the gripper cylinder 311, a rotary cylinder 313 connected to the gripper cylinder, and a lifting cylinder 314 for the flipping mechanism connected to the rotary cylinder. The lifting cylinder for the flipping mechanism is mounted on the flipping mechanism frame 315. The flipping mechanism frame 315 is mounted on the unloading mechanism frame 34, which is mounted on the worktable. The fixed plate 15 is mounted on a pair of uprights 18, which are mounted on the worktable. The unloading plate 32 is mounted on the unloading mechanism frame 34. After the product is oiled on both sides and cooled, the product held by the grippers 312 descends under the drive of the lifting cylinder 314 for the flipping mechanism, falls onto the unloading plate 32, and is unloaded.

[0034] As an improvement, combined Figure 6 , Figure 8The feeding plate 32 is inclined and has a through hole 320. A buffer head 331 is installed in the through hole and fits onto a buffer seat 332. A telescopic spring 334 is provided between the buffer head and the buffer seat. The buffer seat is connected to a buffer lifting cylinder 335. The buffer head is located below a pair of grippers 312. Because the feeding plate is inclined, the product falling vertically will impact the feeding plate 32 on at least one side. Therefore, the buffer lifting cylinder 335 drives the buffer seat 332 and the buffer head 331 to rise. The product from the pair of grippers 312 first falls onto the buffer head 331. Then, driven by the buffer lifting cylinder 335, the buffer head 331 slowly descends. The buffer seat 332 and the buffer head 331 can pass downward through the through hole 320, and the product slowly falls onto the feeding plate 32. Afterward, the product slides down the feeding plate 32 and is unloaded.

[0035] 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.
