Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to an assembly line for a rotary switch cover assembly. Background Technology

[0002] The rotary switch cover assembly is a core control component of the automotive electronic control system. It relies on manual rotation or toggle operation to switch gears and function modes, and is widely used in various vehicle function adjustment scenarios. This assembly mainly consists of a knob cap 100, a cover 200, a rotor assembly 300, a transmission lever 400, a top pin 500, and a top pin spring 600. The cover 200 has an open-bottomed assembly cavity 201 inside, and a track seat 202 is inserted into the cavity. The rotor assembly 300 is mounted inside the track seat 202. The specific structure of the rotor assembly 300 is disclosed in patent CN118682463A, and it mainly includes a rotor seat 301, an upper spring 302, a contact piece 303, a side spring 304, and a positioning pin 305. The bottom and side walls of the sub-base 301 are provided with slots. A spring 302 and a contact piece 303 are installed in the bottom slot. There is a pair of contact pieces. A side spring 304 and a positioning pin 305 are installed in the side wall slot. The positioning pin 305 abuts against the track seat 202 under the elastic force of the side spring 304. A vertical through mounting hole 3011 is provided in the center of the rotor seat 301. A corresponding insertion hole 203 is provided on the upper end of the top cover 200. The lower end of the transmission lever 400 is provided with an insertion channel 401. The top pin spring 600 and the top pin 500 are sequentially installed in the channel. During assembly, the upper end of the transmission lever passes through the mounting hole of the rotor seat and the insertion hole of the top cover in sequence, and is inserted with the knob cap to form a linkage structure. The transmission lever and the rotor assembly are in synchronous rotational cooperation. When the knob cap is rotated, the transmission lever can be driven to rotate synchronously, thereby driving the rotor assembly to rotate along the inner side of the track seat. The contact piece moves in a circle with the rotor assembly. By switching the contact piece with different conductive points on the circuit board, the gear or function mode adjustment is completed. When the knob cap is turned, the transmission lever can swing relative to the rotor assembly, and drive the top pin to swing to complete the corresponding adjustment action.

[0003] In the existing structure, locating pins 305 are installed on both sides of the rotor base 301. The two locating pins 305 are staggered vertically and abut against the side springs 304 on the corresponding sides. During assembly, due to the different installation heights of the two locating pins 305, the end of the first locating pin 3051, located at the top, presses against the upper end of the inner circumferential wall of the track seat 202, while the end of the second locating pin 3052, located at the bottom, rests on the lower edge of the track seat 202. Furthermore, the inner circumferential wall of the track seat no longer extends downwards. Due to the lateral thrust of the springs on both sides at different heights, the end of the second locating pin tilts downwards and supports the bottom surface of the track seat, causing the rotor assembly to become significantly skewed. After this skew, the mounting hole of the rotor seat and the insertion hole of the top cover become significantly misaligned, making it difficult to insert the transmission lever. This leads to jamming during assembly and a high product rework rate. Moreover, because the transmission lever lacks effective positioning constraints, it will wobble after assembly and cannot maintain a vertical position. This makes it difficult to accurately insert the subsequent top pin spring and top pin in the vertical direction, often resulting in problems such as top pin insertion jamming and incomplete assembly. Overall, the assembly quality is difficult to control, and production efficiency is low. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides an assembly line for a rotary switch cover assembly, which achieves precise positioning of the workpiece, continuous connection of processes, and recycling of pressure blocks, thereby improving assembly yield and production stability.

[0005] The technical solution of this invention: An assembly line for a rotary switch cover assembly, comprising a processing track and a pressing block conveying track, wherein the processing track is sequentially divided into a knob cap loading station area, a cover loading station area, a track seat assembly station area, a pressing block loading station area, a rotor assembly loading station area, a lever assembly station area, a pressing block unloading station area, a top pin spring assembly station area, and a top pin assembly station area. Each station area is correspondingly equipped with a knob cap loading unit, a cover loading unit, a track seat assembly unit, a pressing block loading unit, a rotor assembly loading unit, a lever loading unit, a pressing block unloading unit, a top pin spring loading unit, and a top pin loading unit. The processing track is provided with a plurality of cover carriers, each cover carrier having a workpiece cavity. The workpiece cavity has a knob cap receiving groove for accommodating an inverted knob cap and an upper cover positioning groove for accommodating an inverted upper cover. The upper cover carrier moves along the processing track and sequentially arrives at each workstation area to await operation. The knob cap feeding unit is used to feed the knob cap to the upper cover carrier at the knob cap feeding workstation area of ​​the processing track, so that the knob cap is vertically placed into the knob cap receiving groove in the workpiece cavity in an inverted state for positioning. The upper cover feeding unit is used to feed the upper cover to the upper cover carrier at the upper cover feeding workstation area of ​​the processing track, so that the upper cover is vertically placed into the upper cover positioning groove in the workpiece cavity in an inverted state for positioning, and this upper cover corresponds to the top of the knob cap. The track seat assembly unit is used to feed the track seat to the upper cover carrier at the track seat assembly workstation area of ​​the processing track, so that the track seat is vertically placed into the upper cover positioning groove in the workpiece cavity in an inverted state for positioning, and this upper cover corresponds to the top of the knob cap. The press block is positioned in an inverted state within the assembly cavity of the upper cover. The press block conveying track carries the press block from the upstream return area to the downstream loading area. Each press block has a vertically penetrating hollow cavity through which the rotor assembly passes, and positioning pin clearance grooves are provided on opposite sides of the hollow cavity. The press block loading unit loads the press blocks from the downstream loading area of ​​the press block conveying track onto the upper cover carrier at the press block loading station area of ​​the processing track. This allows the press block to be placed vertically onto the track seat inside the upper cover carried by the upper cover carrier, with the inner circumferential wall of the press block flush with the inner circumferential wall of the track seat, forming a vertically extending limiting surface. The upper end of the press block is also exposed outside the upper cover. The rotor assembly loading unit loads the rotor assembly onto the rotor assembly loading station of the processing track. The upper cover carrier in the processing track loading area feeds the rotor assembly vertically through the hollow cavity of the pressure block on the upper cover carrier in an inverted state and places it inside the track seat. The second positioning pin of the rotor assembly abuts against the limiting surface to prevent the end of the second positioning pin from tilting upward to the bottom surface of the track seat, so that the assembly hole of the rotor seat and the insertion hole of the upper cover are aligned and connected. The transmission lever loading unit is used to feed the transmission lever to the upper cover carrier in the processing track lever assembly station area, so that the transmission lever is inverted and inserted into the assembly hole of the rotor seat and the insertion hole of the upper cover carrier, and then forms an insertion assembly with the knob cap. The pressure block unloading unit is used to remove the pressure block from the upper cover carrier in the processing track pressure block unloading station area and place it in the upstream return area of ​​the pressure block conveying track.The top pin spring feeding unit is used to feed the top pin springs onto the upper cover carrier at the top pin spring assembly station area of ​​the machining track, so that the top pin springs are vertically inserted into the transmission lever insertion channel, which is calibrated to a vertical position; the top pin feeding unit is also used to feed the top pins onto the upper cover carrier at the top pin assembly station area of ​​the machining track, so that the top pins are vertically inserted into the transmission lever insertion channel, which is calibrated to a vertical position, in an inverted state.

Each workstation is equipped with a corresponding feeding or assembly unit. The processing track has several top cover carriers, each with a workpiece cavity containing a knob cap receiving slot and a top cover positioning slot. The top cover carriers move along the track to each workstation. The knob cap feeding unit inverts the knob cap and places it into the knob cap receiving slot of the workpiece cavity of the top cover carrier for positioning. The top cover feeding unit inverts the top cover and places it into the top cover positioning slot of the workpiece cavity of the top cover carrier, with the top cover positioned above the knob cap. The track seat assembly unit inverts the track seat and places it into the top cover assembly cavity for positioning. The pressure block conveying track carries the pressure blocks from the upstream return area to the downstream feeding area. The pressure blocks have a middle... The production line includes a cavity and a positioning pin clearance groove; the pressing block feeding unit places the pressing block on the inner track seat of the upper cover carrier, with the pressing block flush with the inner peripheral wall of the track seat to form a limiting surface; the rotor assembly feeding unit inverts the rotor assembly, passes it through the hollow cavity of the pressing block, and inserts it into the inner side of the track seat, with the second positioning pin abutting and limiting, making the rotor seat assembly hole and the upper cover insertion hole connected; the transmission lever feeding unit inverts the transmission lever, inserts it through the rotor seat assembly hole and the upper cover insertion hole, and then inserts it into the knob cap; the pressing block unloading unit moves the pressing block out of the upper cover and places it in the upstream return area of ​​the pressing block conveying track; the top pin spring feeding unit vertically inserts the top pin spring into the transmission lever insertion channel; the top pin feeding unit inverts the top pin and inserts it into the transmission lever insertion channel; this production line achieves precise positioning of the workpiece posture, continuous connection of processes, and recycling of pressing blocks, improving assembly yield and production stability.

The first storage-type automatic loading and unloading device is equipped with a stackable first material tray. The surface of the first material tray has a plurality of knob cap receiving slots for accommodating knob caps in an inverted state. A single first material tray can be sequentially loaded to the knob cap picking station. The end effector of the first industrial robotic arm is equipped with a knob cap gripper. The knob cap gripper is used to grip the knob caps in the knob cap receiving slots of the first material tray at the knob cap picking station, and the first industrial robotic arm transfers the knob caps gripped by the knob cap gripper to the knob cap receiving slot of the upper cover carrier workpiece cavity.

The surface of the third material tray has several rotor receiving slots for receiving the inverted rotor assembly. A single third material tray can be fed sequentially to the rotor picking station. The execution end of the third industrial robotic arm is equipped with a rotor gripper. The rotor gripper is used to hold the rotor assembly in the rotor receiving slot of the third material tray at the rotor picking station. The rotor assembly held by the rotor gripper is transferred and transported to the inner side of the track seat inside the upper cover.

[0008] By further configuring the above-mentioned automatic loading and unloading equipment and industrial robotic arms, the storage equipment can stack material trays. The material trays are pre-cut with receiving slots that are adapted to the shape of the workpiece, so that the knob cap, top cover, and rotor assembly are placed stably in a specified inverted posture. The end of the industrial robotic arm is equipped with a special gripper. The shape of the gripper is precisely matched with the shape of the workpiece, ensuring that the posture remains unchanged, the force is uniform, and the workpiece is not damaged during gripping. The robotic arm moves precisely along a preset trajectory, and after gripping the workpiece from the material tray, it is smoothly transferred to the workpiece cavity of the upper cover carrier of the corresponding workstation on the processing track, completing the automatic loading and posture calibration of the workpiece.

The drive module can drive a pair of track seat abutment plates to move closer or further apart. The positioning surfaces of the pair of track seat abutment plates abut against the two sides of the outer wall of the track seat to perform position positioning and correction of the track seat placed on the upper cover carrier. The track seat transport mechanism includes a second track seat gripper, a first vertical sliding drive module and a first horizontal sliding drive module. The first horizontal sliding drive module drives the second track seat gripper to move horizontally, and the first vertical sliding drive module drives the second track seat gripper to move vertically up and down. The second track seat gripper, after being adjusted in position, clamps the corrected track seat and transports it into the upper cover assembly cavity on the corresponding upper cover carrier to complete the positioning and assembly.

[0010] With the above-mentioned further configuration, through the coordinated operation of the track seat feeding tray equipment, industrial robotic arm, track seat adjustment mechanism, and conveying mechanism, the feeding tray equipment disperses the disorderly stacked track seats one by one through vibration, ensuring that the workpiece posture is controllable; the end gripper of the industrial robotic arm accurately grasps a single track seat and transfers it to the track seat adjustment mechanism; the adjustment mechanism is equipped with a pair of sliding abutment plates, the inner side of which forms a positioning surface that fits against the outer wall of the track seat.

The second vertical sliding drive module is used to drive the first briquetting gripper to move the briquetting blocks vertically up and down. The second horizontal sliding drive module is used to drive the first briquetting gripper to move the briquetting blocks horizontally, thereby realizing the movement of the briquetting blocks between the downstream loading area of ​​the briquetting conveyor track and the briquetting loading station area of ​​the processing track. The cross-track transfer is achieved by the processing track block unloading station area and the upstream return area of ​​the block conveying track, both of which are located below the block unloading unit. The block unloading unit includes a second block gripper, a third vertical sliding drive module, and a third horizontal sliding drive module. The second block gripper is used to hold the block in the processing track block unloading station area. The third vertical sliding drive module is used to drive the second block gripper to move the block vertically up and down. The third horizontal sliding drive module is used to drive the second block gripper to move the block horizontally, thereby achieving cross-track transfer of the block between the processing track block unloading station area and the upstream return area of ​​the block conveying track.

[0012] With the above-described further configuration, the briquetting loading unit and briquetting unloading unit are respectively equipped with grippers and vertical and horizontal sliding drive modules. The briquetting conveyor track transports briquetting blocks from the upstream return area to the downstream loading area, achieving directional circulation of briquetting blocks. The grippers of the briquetting loading unit grab briquetting blocks from the downstream loading area. The vertical drive module drives the grippers to rise, and the horizontal drive module drives the grippers to move laterally to directly above the briquetting loading station on the processing track. The vertical drive module then drives the grippers to descend, smoothly placing the briquetting block onto the track seat, completing cross-track loading. The grippers of the briquetting unloading unit grab briquetting blocks from the briquetting unloading station on the processing track. Through the reverse actions of vertical rising, horizontal sliding, and vertical falling, the briquetting block is transferred to the upstream return area of ​​the briquetting conveyor track, completing cross-track unloading. This achieves automated cross-track transfer of briquetting blocks between the processing track and the briquetting conveyor track, ensuring consistent loading position and posture, and automatic recycling after unloading, avoiding positional deviations caused by manual handling.

[0035] During operation, the first lever straightening mechanism moves downwards, clamping the swaying transmission lever with a pair of straightening claws and correcting it to a vertical position. The top pin spring feeding tray arranges the top pin springs one by one through vibration, and then conveys them to the top pin spring receiving position via the first direct-vibration feeding rail. After the first sensor confirms that the position is in place, the first top pin spring gripper of the first top pin spring transport mechanism grabs the horizontal top pin spring and moves it to the top pin spring flipping and erecting mechanism. After the second top pin spring gripper clamps the top pin spring, it is rotated 90 degrees by the first flipping adjustment drive module to adjust the top pin spring to an inverted upright position. Then, the third top pin spring gripper of the second top pin spring transport mechanism grabs the upright top pin spring and moves it to the top of the vertically aligned transmission lever insertion channel. The top pin spring is then placed vertically downwards and inserted into the insertion channel. Finally, the spring pressing mechanism presses down on the top pin spring, completely pressing it into the insertion channel of the transmission lever, completing the automatic feeding and assembly of the top pin spring.

[0036] Specifically, the top pin feeding unit 1021 includes a top pin feeding tray device 1102, a top pin adjustment and assembly mechanism 1103, and a second lever straightening mechanism 1104.

The top pin flipping and inverting mechanism 1108... 08 includes a top pin receiving gripper 11081, a second flip adjustment drive module 11082, and a second sensor 11025. The top pin receiving gripper 11081 is connected to the power output end of the second flip adjustment drive module 11082. The top pin receiving gripper 11081 is used to receive and accommodate the horizontally lying top pin output from the top pin discharge position 11023, and the second flip adjustment drive module 11082 drives the top pin receiving gripper 11081 to rotate around the horizontal axis, so that the top pin is flipped and adjusted to an inverted vertical state.

The top pin; the top pin transport mechanism 1109 includes a top pin gripper 11091, an eighth vertical sliding drive module 11092 and a seventh horizontal sliding drive module 11093.

The top pin gripper 11091 is used to grab the top pin in the inverted vertical state after flipping from the top pin flipping and inverting mechanism 1108, and move it to the top of the transmission lever insertion channel that has been corrected to a vertical state, and insert the top pin into the insertion channel.During operation, the second lever straightening mechanism first moves down to clamp the swaying transmission lever, correcting it to maintain a vertical position. The top pin feeding tray equipment uses vibration to arrange and transport the disordered top pins one by one. The horizontally lying top pins are sent to the top pin discharge position at the discharge end via the second vertical vibration feeding rail. When the top pin receiving gripper aligns with the top pin discharge position, it can receive and clamp the horizontally lying top pins output from the top pin discharge position. After the second sensor confirms that the top pin is in place, it drives the top pin receiving gripper to rotate 90 degrees around the horizontal axis through the second flip adjustment drive module, so that the top pin is flipped and adjusted to an inverted vertical position. Subsequently, the top pin transport mechanism's top pin gripper grabs the adjusted inverted vertical top pin, moves it horizontally to the top of the corresponding upper cover carrier, and vertically lowers it to insert the top pin into the insertion channel of the transmission lever. With the help of the pre-installed top pin spring, it completes the elastic snap-fit ​​assembly, realizing the automatic feeding and assembly of the top pins.

The positioning abutment surfaces 10583 of the pair of positioning plates 10581 abut against the two sides of the outer wall of the top cover, respectively, to perform position positioning and correction on the top cover placed on the top cover carrier 1022. During operation, the second backplate sliding drive module drives a pair of positioning backplates to move closer to each other. The positioning abutment surfaces on both sides simultaneously abut against the corresponding corners of the outer wall of the top cover, pushing the top cover to fine-tune its position so that the top cover is adjusted to the predetermined assembly position of the processing station. After the positioning correction is completed, each unit then carries out the corresponding assembly operation to avoid the subsequent assembly accuracy being affected by the position offset of the top cover.

During operation, the contact detection unit uses the first metal proximity switch to detect whether the contact is accurately assembled. If a missing contact is detected, it can be directly sorted and rejected in subsequent processes. The lever oiling unit uses the metering valve to apply lubricating oil to the mating surface of the transmission lever according to a set amount after the transmission lever is assembled. The top pin detection unit uses the second metal proximity switch to detect whether the top pin is successfully inserted into the insertion channel of the transmission lever, confirming the top pin assembly status and preventing defective products with missing parts from flowing into the next process.

[0039] In this embodiment, all of the above-mentioned sliding drive modules adopt conventional designs, such as linear slide module structures, which use servo motors in conjunction with ball screws and linear guides to achieve precise reciprocating movement, or directly use cylinders, electric cylinders, etc. as power sources for drive; the above-mentioned grippers can be pneumatic grippers with adjustable clamping force to firmly hold the workpiece.

[0041] The aforementioned detection cameras, sensors, metering valves, metal proximity switches, etc., are conventionally designed and connected to the host computer via signals. When the detection detects abnormalities in the orientation or position of parts or material shortages, it can send a signal to the host computer to suspend the production line and issue an alarm.

[0042] This assembly line, through the orderly cooperation of each workstation unit, can automatically complete the sequential feeding, positioning and alignment of each component of the rotary switch cover assembly, eliminating the need for manual assembly and significantly improving the assembly efficiency of the rotary switch cover assembly. At the same time, the setting of various testing mechanisms ensures the assembly direction and positional accuracy of the components, thereby improving the assembly yield.
