Description

Technical Field

[0001] This invention relates to the field of switch manufacturing equipment technology, specifically to an automated system for seat adjustment switches in new energy vehicles. Assembly equipment. Background Technology

[0002] Currently, the seat adjustment switches in new energy vehicles are all located on the side of the seat, covering both manual and automatic adjustment modes. They typically offer three adjustment methods: fore-aft, up-down, and backrest adjustment, in order to achieve better driving comfort.

[0003] Existing assembly equipment for new energy vehicle seat adjustment switches has several drawbacks after long-term use: 1. When assembling the built-in slider and circuit board after the outer shell is positioned, the current technology uses a vibratory feeder to place the built-in slider into the corresponding groove position inside the shell, relying on resistance. However, the high-frequency vibration of the equipment can cause the placed built-in slider to slide, leading to deviations in the subsequent assembly of the circuit board with the three-way dial. If the deviation is small, it can be self-aligned according to the transition edge of the component. However, if the deviation is large, the reset effect of the dial after assembly will be affected. 2. The end of the circuit board has multiple sets of metal contacts connected to the vehicle control system. The existing seat adjustment switch pre-assembles the circuit board with metal contacts directly into the shell and then performs protective assembly of the metal contacts. However, this method not only adds an extra processing step, but also often damages the contacts on both sides during the reassembly of the metal contacts, requiring rework and correction after quality inspection. Summary of the Invention

[0004] The purpose of this invention is to provide an automated assembly equipment for seat adjustment switches in new energy vehicles, so as to solve the above-mentioned defects caused by the prior art.

[0005] An automated assembly equipment for a seat adjustment switch in a new energy vehicle includes a frame, a conveyor belt, a positioning mechanism, and an assembly mechanism. A steering limit rod is adjustablely installed on the frame. The conveyor belt is installed on the frame. The positioning mechanism is installed on the frame and is used to pre-position the housing and built-in sliding plate of the seat adjustment switch. The assembly mechanism is also installed on the frame and is used to tilt and insert the circuit board of the seat adjustment switch and to automatically assemble the sealing cover.

[0006] Preferably, the positioning mechanism includes a positioning seat and a negative pressure cover. The positioning seat is mounted on the frame and has a limiting groove. The negative pressure cover is mounted on the frame and communicates with the limiting groove.

[0007] Preferably, the assembly mechanism includes a drive motor, a steering mounting bracket, and a rack. The drive motor is mounted on the frame, and a rocker arm is mounted on the output end of the drive motor. A guide ring is slidably disposed at the end of the rocker arm, and the guide ring is also slidably disposed on the side end of the frame. The rack is vertically mounted on the side end of the guide ring. Two symmetrically arranged sliding columns are fixedly connected to the lower end of the guide ring. The steering mounting bracket is slidably disposed on the sliding columns without being restricted. A spring is sleeved on the sliding columns between the guide ring and the steering mounting bracket. Top support rods are slidably disposed on both sides of the steering mounting bracket. One end of the top support rod abuts against the sliding column, and the other end of the top support rod is connected to the steering mounting bracket by a tension spring. An assembly pressure plate is mounted on the lower end of the steering mounting bracket. A flipping pressing part is hinged to the negative pressure cover. A gear that meshes with a gear is coaxially mounted on the hinge side end of the flipping pressing part.

[0008] Preferably, the lower end of the housing of the seat adjustment switch is provided with a limiting post that cooperates with the limiting groove.

[0009] Preferably, the lower end surface of the assembly plate has a horizontal and inclined structure, and an avoidance opening is provided on the inclined surface.

[0010] Preferably, the clearance opening cooperates with the sliding column in the vertical direction, and an arc-shaped limiting groove is also provided on the inclined surface, which cooperates with the steering limiting rod.

[0011] Preferably, when the guide ring is at its highest position, the sealing cover plate on the flip-press part is clamped and pressed into the housing of the seat adjustment switch.

[0012] Preferably, when the guide ring is in its highest and lowest position, the upper end face of the flip-pressing part mates with the conveyor belt in the horizontal direction.

[0013] The advantages of this invention are: By setting a positioning mechanism and an assembly mechanism on the frame, the negative pressure of the negative pressure cover positions the housing on the positioning seat. After the sliding groove inside the housing is attracted and positioned for front and back, up and down, and backrest built-in sliding pieces, the output end of the drive motor drives the guide ring downward through the end of the rocker arm. When the inclined surface structure of the lower end of the assembly plate contacts the steering limit rod, it causes the assembly plate to rotate at a fixed angle. After the bottom surface of the circuit board contacts the stepped positioning ridge inside the housing, as the guide ring continues to move downward, the steering mounting bracket will return from the inclined state to the horizontal state. Under the continuous support of the spring, the non-metallic contact end of the circuit board is assembled with the built-in sliding pieces, the circuit board with metal contacts, and the housing under the action of the inclined and chamfered transition treatment of the housing. This reduces the assembly deviation between the circuit board and the three-way built-in sliding pieces and avoids affecting the reset effect of the dial after assembly.

[0014] As the rocker continues to rotate, it drives the guide ring to reset and move upward. Then, through the rack and gear, it drives the flipping pressing part with the sealing cover to flip in the opposite direction until the guide ring is raised to the highest position. At this point, the flipping pressing part drives the sealing cover to complete the final assembly with the housing with the pre-installed built-in slider and circuit board. No subsequent protective assembly process is required, which ensures the assembly and processing quality of the seat adjustment switch. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, an automated assembly equipment for a seat adjustment switch for a new energy vehicle includes a frame 1, a conveyor belt 2, a positioning mechanism 3, and an assembly mechanism 4. A steering limit rod 5 is adjustablely installed on the frame 1. The conveyor belt 2 is installed on the frame 1. The positioning mechanism 3 is installed on the frame 1 and is used to pre-position the housing 6 of the seat adjustment switch and the built-in sliding plate 7. The assembly mechanism 4 is also installed on the frame 1 and is used to tilt and insert the circuit board 8 of the seat adjustment switch and to automatically assemble the sealing cover plate 9.

[0023] In this embodiment, the positioning mechanism 3 includes a positioning seat 31 and a negative pressure cover 32. The positioning seat 31 is mounted on the frame 1 and has a limiting groove 33. The negative pressure cover 32 is mounted on the frame 1 and is connected to the limiting groove 33.

[0024] In this embodiment, the assembly mechanism 4 includes a drive motor 401, a steering mounting bracket 402, and a rack 403. The drive motor 401 is mounted on the frame 1, and a rocker arm 404 is mounted on the output end of the drive motor 401. A guide ring 405 is slidably disposed at the end of the rocker arm 404, and the guide ring 405 is also slidably disposed on the side end of the frame 1. The rack 403 is vertically mounted on the side end of the guide ring 405, and two symmetrically arranged sliding columns 406 are fixedly connected to the lower end of the guide ring 405. The steering mounting bracket 402 is slidably disposed on the rack 403 without being limited. On the column 406, a spring 407 is sleeved between the guide ring 405 and the steering mounting bracket 402. Top support rods 408 are slidably arranged on both sides of the steering mounting bracket 402. One end of the top support rod 408 abuts against the column 406, and the other end of the top support rod 408 is connected to the steering mounting bracket 402 by a tension spring 409. An assembly pressure plate 410 is installed at the lower end of the steering mounting bracket 402. A flipping pressing part 411 is hinged on the negative pressure cover 32. A gear 412 that meshes with the gear 412 is coaxially installed on the hinge side of the flipping pressing part 411.

[0025] It should be noted that the drive motor 401 is a servo motor, which can control the initial height position of the steering mounting bracket 402.

[0026] In this embodiment, the lower end of the housing 6 of the seat adjustment switch is provided with a limiting post that cooperates with the limiting groove 33.

[0027] In this embodiment, the lower end face of the assembly pressure plate 410 has a horizontal and inclined structure, and an avoidance opening 413 is provided on the inclined surface.

[0028] In this embodiment, the clearance opening 413 cooperates with the sliding column 406 in the vertical direction, and an arc-shaped limiting groove 414 is also provided on the inclined surface. The limiting groove 414 cooperates with the steering limiting rod 5.

[0029] In this embodiment, when the guide ring 405 is at its highest position, the sealing cover 9 on the flip-press part 411 is clamped and pressed into the housing 6 of the seat adjustment switch.

[0030] It is worth mentioning that the end of the housing 6 away from the metal contact assembly port of the circuit board 8 is treated with a chamfered transition, which allows the circuit board 8 to complete the transition from a tilted state to a horizontal state during the assembly process.

[0031] Furthermore, when the guide ring 405 is in its highest and lowest position, the upper end face of the flip-press part 411 engages with the conveyor belt 2 in the horizontal direction.

[0032] Working process and principle: In the use of this invention, firstly, according to the corresponding model of the seat adjustment switch, adjust and fix the installation position of the steering limit rod 5 on the frame 1. Then, the operator places the housing 6, which has a limit post at the lower end, on the limit groove 33. Under the negative pressure adsorption of the negative pressure cover 32, the housing 6 is positioned on the positioning seat 31, and then slides into the housing 6. The corresponding front, back, top, bottom, and backrest built-in sliding plates 7 are placed in the slot, and they are also positioned in the corresponding positions inside the housing 6 under negative pressure suction to prevent the equipment from vibrating and causing it to slide.

[0033] Then, under negative pressure, the circuit board 8 is placed on the upper limit of the assembly plate 410, and the drive motor 401 is started so that its output end drives the rocker arm 404 to rotate. During the sliding process of the end of the rocker arm 404 in the guide ring 405, it will drive the lower end of the sliding column 406 to move down. Under the elastic support of the spring 407, the steering mounting bracket 402 and the assembly plate 410 will move down synchronously. When the inclined surface structure of the lower end of the assembly plate 410 contacts the steering limit rod 5, it will cause the assembly plate 410 to tilt and flip until the steering limit rod 5 enters the limit groove 414 and stops flipping.

[0034] At this time, the assembly plate 410 drives the circuit board 8 to rotate synchronously at a fixed angle. After the bottom surface of the circuit board 8 contacts the stepped positioning rib inside the housing 6, as the guide ring 405 continues to descend, the steering mounting bracket 402 will return from the tilted state to the horizontal state. Under the continuous support of the spring 407, the non-metallic contact end of the circuit board 8 completes the direct one-time assembly of the built-in slider 7, the circuit board 8 with metal contacts, and the housing 6 under the action of the inclined chamfered transition treatment of the housing 6. This process will also drive the flipping pressing part 411 to rotate clockwise to the right side under the action of the rack 403 and the gear 412 meshing with it.

[0035] Then, the conveyor belt 2 is started, which drives the sealing cover plate 9 on it to be placed on the flipping pressing part 411 under negative pressure. As the rocker arm 404 continues to rotate, it drives the guide ring 405 to reset and move upward. Then, the rack 403 and gear 412 drive the flipping pressing part 411 with the sealing cover plate 9 to flip in the opposite direction until the guide ring 405 is raised to the highest position. Then, the flipping pressing part 411 drives the sealing cover plate 9 to complete the final assembly with the housing 6 with the built-in sliding plate 7 and circuit board 8 pre-installed.

[0036] Based on the above, the present invention sets a positioning mechanism 3 and an assembly mechanism 4 on the frame 1. The negative pressure of the negative pressure cover 32 causes the housing 6 to be positioned on the positioning seat 31. After the sliding groove inside the housing 6 is attracted and positioned front and back, up and down, and backrest built-in sliding piece 7, the output end of the drive motor 401 drives the guide ring 405 to move downward through the end of the rocker arm 404. When the inclined surface structure of the lower end face of the assembly pressure plate 410 contacts the steering limit rod 5, the assembly pressure plate 410 is rotated at a fixed angle. After the bottom surface of the circuit board 8 contacts the stepped positioning ridge inside the housing 6, as the guide ring 405 continues to move downward, the steering mounting bracket 402 will return from the inclined state to the horizontal state. Under the continuous support of the spring 407, the non-metallic contact end of the circuit board 8 is assembled with the built-in sliding piece 7, the circuit board 8 with metal contact piece and the housing 6 under the action of the inclined chamfered transition treatment of the housing 6. This reduces the assembly deviation between the circuit board 8 and the three-way built-in sliding piece 7 and avoids affecting the reset effect of the dial after assembly.

[0037] As the rocker arm 404 continues to rotate, it drives the guide ring 405 to reset and move upward. Then, the rack 403 and gear 412 drive the flipping pressing part 411, which has the sealing cover plate 9, to flip in the opposite direction until the guide ring 405 is raised to the highest position. The flipping pressing part 411 drives the sealing cover plate 9 to complete the final assembly with the housing 6, which has the built-in slider 7 and circuit board 8 pre-installed. No subsequent protective assembly process is required, which ensures the assembly and processing quality of the seat adjustment switch.

[0038] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or equivalent to the scope of this invention are included in this invention.
