Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a rotor assembly equipment 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, with a track seat 202 installed within 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 rotor base 301 has slots on its bottom and side walls. A spring 302 and a contact piece 303 are installed in the bottom slot, and a side spring 304 and a positioning pin 305 are installed in the side wall slot. The positioning pin 305 abuts against the track base 202 under the elastic force of the side spring 304. A vertical through mounting hole 3011 is opened in the center of the rotor base 301, and 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, and the top pin spring 600 and the top pin 500 are sequentially installed inside 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 above presses against the upper end of the inner peripheral wall of the track seat 202, while the end of the second locating pin 3052 located below rests on the lower edge of the track seat 202, and the inner peripheral wall of the track seat no longer extends downward. Under the lateral thrust of different heights formed by the springs on both sides, the end of the second locating pin tilts downward and supports the bottom surface of the track seat, causing the rotor assembly to become significantly skewed. After the rotor assembly is skewed, the mounting hole of the rotor seat and the insertion hole of the top cover are significantly misaligned, making it difficult to insert the transmission lever. The assembly process is prone to jamming, resulting in a high product rework rate. Even if the second locating pin is manually pressed into the inside of the track seat during assembly, it will still tilt back after being released, causing the rotor assembly to return to significant skew, which in turn affects the subsequent assembly of the transmission lever. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art by providing a rotor assembly equipment for a rotary switch cover assembly, which realizes the alignment and assembly of the transmission lever with the rotor assembly, the cover, and the knob cap, and solves the problem of large alignment deviation caused by the lack of anti-warping structure in traditional assembly.

[0005] The technical solution of this utility model is: a rotor assembly equipment for a rotary switch cover assembly, including a processing track and a block conveying track. The processing track is divided into a block loading station area, a rotor assembly loading station area, a lever assembly station area and a block unloading station area along the conveying direction. Each station area is equipped with a block loading unit, a rotor assembly loading unit, a transmission lever assembly unit and a block unloading unit. The processing track is provided with several carriers, each carrier having a workpiece cavity. The workpiece cavity is divided into a knob cap receiving groove for accommodating an inverted knob cap and a top cover positioning groove for accommodating an inverted top cover. The knob cap, top cover, and track seat inside the top cover constitute a top cover pre-assembly assembly. This top cover pre-assembly assembly moves along the processing track with the carrier and arrives at each workstation in sequence to wait for operation. The briquette conveying track is used to carry the briquette and transport it from the upstream return area to the downstream loading area. The briquette has a hollow cavity that is vertically opened for the rotor assembly to pass through, and the hollow cavity is provided with positioning pin clearance grooves on opposite sides. The briquetting feeding unit is used to feed the briquetting blocks on the feeding area downstream of the briquetting conveying track to the carrier in the briquetting feeding station area of ​​the processing track, so that the briquetting blocks are placed vertically downward on the track seat provided inside the upper cover carried by the carrier, and the inner peripheral wall of the briquetting blocks is flush with the inner peripheral wall of the track seat to form a vertically extended limiting surface, and the upper end of the briquetting blocks is also exposed outside the upper cover. The rotor assembly feeding unit is used to feed the rotor assembly to the carrier in the processing track rotor assembly feeding station area, so that the rotor assembly passes vertically through the hollow cavity of the pressure block on the carrier in an inverted state and is placed inside the track seat. The second positioning pin of the rotor assembly abuts against the limiting surface to limit 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 is aligned and connected with the insertion hole of the upper cover. The transmission lever assembly unit is used to feed the transmission lever to the 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 cover on the carrier, and then forms an insertion assembly with the knob cap. The briquetting unloading unit is used to remove the briquetting blocks from the inside of the upper cover of the carrier in the briquetting unloading station area of ​​the processing track and place them in the upstream return area of ​​the briquetting conveying track.

[0006] By adopting the above technical solution, the processing track is divided into multiple workstation areas according to the assembly process and matched with corresponding work units. This allows the pressure blocks, rotor assemblies, and transmission levers to be automatically loaded and assembled sequentially according to the process order. The entire assembly process is smooth and continuous, achieving fully automated operation and effectively improving overall assembly efficiency. The carrier has a workpiece cavity with a knob cap receiving slot and a cover positioning slot, enabling simultaneous positioning of inverted knob caps and covers, ensuring uniform workpiece placement and preventing workpiece offset or skew. This provides a reliable positioning basis for subsequent assembly processes. As the carrier moves along the processing track, it stably drives the workpieces to each workstation, ensuring orderly process connections. The pressure block conveyor track achieves a closed-loop feeding structure, continuously supplying pressure blocks to the assembly stations and preventing equipment downtime due to material supply interruptions. The pressure blocks have a through-hole hollow cavity and a positioning pin avoidance slot, adapting to the rotor assembly insertion requirements without affecting the rotor. The locating pin of the assembly creates an obstruction. After the pressure block is placed on the track seat of the upper cover, the inner circumferential walls of the two are flush and joined to form a continuous limiting surface. This structure can abut and limit the second locating pin of the rotor assembly, preventing the locating pin from tilting upwards. This effectively avoids large-angle skew of the rotor assembly, ensuring that the assembly hole of the rotor seat can be aligned and connected with the insertion hole of the upper cover. This facilitates the smooth insertion of the subsequent transmission lever and solves the problem of misalignment and assembly jamming caused by the tilting of the locating pin in traditional assembly, improving the assembly qualification rate and assembly efficiency. After assembly, the pressure block unloading unit will remove the pressure block from the inside of the assembled upper cover and send it back to the upstream return area of ​​the pressure block conveying track, realizing the recycling and reuse of the pressure block.

[0007] A further feature of this invention is that the downstream loading area of ​​the block conveying track and the block loading station area of ​​the processing track are both located below the block loading unit. The block loading unit includes a first block gripper, a first vertical sliding drive module, and a first horizontal sliding drive module. The first block gripper is used to hold the block in the downstream loading area of ​​the block conveying track. The first vertical sliding drive module is used to drive the first block gripper to move the block vertically up and down. The first horizontal sliding drive module is used to drive the first block gripper to move the block horizontally, thereby realizing the cross-track transfer of the block between the downstream loading area of ​​the block conveying track and the block loading station area of ​​the processing track. The processing track block unloading station area and the upstream return area of ​​the block conveying track are both located below the block unloading unit. The block unloading unit includes a second block gripper, a second vertical sliding drive module, and a second horizontal sliding drive module. The second block gripper is used to hold the block in the processing track block unloading station area. The second vertical sliding drive module is used to drive the second block gripper to move the block vertically up and down. The second horizontal sliding drive module is used to drive the second block gripper to move the block horizontally, so as to realize the cross-track transfer of the block between the processing track block unloading station area and the upstream return area of ​​the block conveying track.

[0008] With the above-mentioned further configuration, the pressing block feeding unit relies on the first pressing block gripper to hold the pressing block, and combined with the vertical sliding drive module and the horizontal sliding drive module, realizes the lifting and lowering and horizontal movement of the pressing block respectively, smoothly completing the cross-rail transfer of the pressing block from the pressing block conveying track to the processing track, and lowering the pressing block onto the track seat of the upper cover, completing the automatic pressing block feeding operation; the pressing block unloading unit relies on the second pressing block gripper to clamp the pressing block on the assembled workpiece, and similarly combined with the corresponding vertical and horizontal sliding drive, smoothly transfers the pressing block from the carrier of the processing track back to the pressing block conveying track, completing the automatic unloading and recycling of the pressing block. The two units work together to realize the automated cyclic transfer of the pressing block without the need for manual intervention in the transfer operation.

[0009] A further feature of this invention is that the rotor assembly feeding unit includes a storage-type automatic loading and unloading device and a first industrial robotic arm. The storage-type automatic loading and unloading device is equipped with stackable material trays. The surface of the material trays has several rotor receiving slots for accommodating rotor assemblies in an inverted state. A single material tray can be sequentially loaded to the rotor picking station. The execution end of the first industrial robotic arm is equipped with rotor grippers. The rotor grippers are used to hold the rotor assemblies in the rotor receiving slots of the material trays at the rotor picking station, and the first industrial robotic arm transfers and transports the rotor assemblies held by the rotor grippers to the inner side of the track seat inside the corresponding upper cover.

[0010] With the above-mentioned further configuration, the warehouse-type automatic loading and unloading equipment can realize the batch stacking and pallet-by-pallet loading of rotor assemblies, greatly extending the interval of manual material replenishment and meeting the needs of long-term continuous operation of the equipment. The rotor receiving slot on the material pallet can stably position and accommodate the inverted rotor assembly, ensuring the uniform placement posture of the rotor assembly and facilitating stable gripping and material picking by the industrial robotic arm. With the flexible handling of the industrial robotic arm, the rotor assembly can be stably and accurately transferred and assembled to the inside of the upper cover, realizing the automated loading operation of the rotor assembly, and ensuring both loading accuracy and loading stability.

[0011] A further feature of this invention: The transmission lever assembly unit includes a lever feeding tray device, a second industrial robotic arm, a lever flipping and erecting mechanism, and a lever conveying mechanism; the lever feeding tray device disperses several transmission levers through vibration; the execution end of the second industrial robotic arm is equipped with a first lever gripper, which is used to grip the transmission levers lying horizontally within the lever feeding tray device and convey them to the lever flipping and erecting mechanism via the second industrial robotic arm; the lever flipping and erecting mechanism includes a second lever gripper and a flipping adjustment drive module, the second lever gripper being connected to the power output end of the flipping adjustment drive module, and the second lever gripper being used to grip the horizontally lying transmission lever and convey it via flipping... The rotary adjustment drive module drives the second lever gripper to rotate upward around the horizontal axis, causing the transmission lever to be flipped and adjusted to an inverted upright state. The lever transport mechanism includes a third lever gripper, a rotary adjustment drive module, a third vertical sliding drive module, and a third horizontal sliding drive module. The third lever gripper is used to hold the inverted upright transmission lever. The rotary adjustment drive module is used to drive the third lever gripper to rotate around the vertical axis, causing the transmission lever to adjust its circumferential angle. The third vertical sliding drive module is used to drive the third lever gripper to move the transmission lever vertically up and down. The third horizontal sliding drive module is used to drive the third lever gripper to move the transmission lever horizontally, transporting the inverted upright transmission lever to the top of the corresponding carrier.

[0012] With the above-mentioned further configuration, the transmission levers are dispersed and organized by the lever feeding tray equipment, and the disordered transmission levers are separated by vibration to facilitate subsequent gripper picking operations; the second industrial robotic arm, in conjunction with the first lever gripper, can stably pick up the transmission levers in a horizontal lying position and transfer them to the lever flipping and uprighting mechanism; the lever flipping and uprighting mechanism holds the workpiece through the second lever gripper, and then the flipping adjustment drive module drives the gripper to rotate, adjusting the horizontal transmission lever to an inverted upright position to meet the required assembly posture; the lever transport mechanism integrates multiple drive modules and the third lever gripper, the rotation adjustment drive module can drive the transmission lever to rotate around the vertical axis to complete the circumferential angle calibration, and the vertical and horizontal sliding drive modules work together to realize the lifting and translation of the workpiece, which can accurately transfer the transmission lever with the posture and angle adjusted to the correct position to the carrier for assembly. The entire mechanism completes the tasks of lever arrangement, material picking, posture flipping, angle correction and transfer in steps. Each action is connected in an orderly manner, which fully ensures the posture and position accuracy of the transmission lever during material feeding and reduces the probability of jamming or misalignment during subsequent assembly.

[0013] A further feature of this invention is that the transmission lever assembly unit also includes a lever detection mechanism, which includes a detection camera and a detection reflection box. The detection reflection box contains an inclined reflector, and has a workpiece observation port at the top and a camera window on the side wall. The detection camera is horizontally positioned, with its lens facing the reflector through the camera window. The detection reflection box is located below the flipped second lever gripper, directly above the workpiece observation port, and projects the image of the transmission lever onto the reflector. The detection camera then captures the image of the transmission lever reflected by the reflector through the camera window.

[0014] By further configuring the above-mentioned settings, an inclined reflector is installed inside the detection reflection box. This, combined with the upper workpiece observation port and the side wall camera window, changes the direction of the light path, allowing the detection camera to be installed horizontally. This eliminates the need to vertically mount the camera directly above the workpiece, avoiding spatial interference between the camera and moving parts such as the upper flipping gripper and transmission lever. Visual inspection of the transmission lever is achieved using reflective imaging, which can clearly capture whether the posture, shape, and position of the transmission lever meet the assembly standards. Workpieces with abnormal postures or misplaced positions can be promptly screened out, preventing unqualified workpieces from entering the assembly station.

[0015] A further feature of this invention is that both the rotor assembly feeding unit and the transmission lever assembly unit include a top cover positioning and correction mechanism. The top cover positioning and correction mechanism includes a pair of top cover abutment plates and a sliding drive module for driving the top cover abutment plates to slide. The top cover abutment plates have positioning abutment surfaces that fit the corners of the outer wall of the top cover. The sliding drive module can drive the pair of top cover abutment plates to move closer or further apart from each other. The positioning abutment surfaces of the pair of top cover abutment plates abut against the two sides of the outer wall of the top cover respectively, so as to perform position positioning and correction of the top cover placed on the carrier.

[0016] With the above-mentioned further configuration, by equipping the upper cover positioning and correction mechanism, the positioning abutment surface of the upper cover abutment plate is adapted to the corner of the outer wall of the upper cover. A pair of upper cover abutment plates move closer or further apart from each other, relying on their positioning abutment surfaces to press against the upper cover from both sides, thereby correcting and clamping the position of the upper cover on the carrier. After correction, the position of the upper cover is fixed and there will be no offset or rotation, effectively preventing problems such as assembly jamming and inaccurate component alignment caused by upper cover position deviation.

[0017] A further feature of this invention is that both the processing track and the pressing block conveying track are linear conveying mechanisms, and the two tracks are arranged side by side. The processing track includes a conveying rail and several trolleys slidably mounted on the conveying rail, and the carrier is mounted on the corresponding trolley.

[0018] With the above-mentioned further configuration, the processing track and the briquetting conveying track are set as parallel linear conveying mechanisms, which have a reasonable spatial layout and facilitate cross-track operation with the matching loading and unloading mechanism. The processing track consists of a conveying rail and a moving trolley. The moving trolley is slidably mounted on the conveying rail, and the carrier is fixedly mounted on the moving trolley. The moving trolley drives the carrier and the workpiece to move smoothly along the track, which can meet the needs of long-term continuous operation of the production line.

Detailed Implementation

[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1-13 As shown, this utility model discloses a rotor assembly device for a rotary switch cover assembly, comprising a processing track 1 and a block conveying track 2. Both the processing track 1 and the block conveying track 2 are linear conveying mechanisms, arranged side by side. The processing track 1 includes a material conveying rail 15 and several trolleys 16 slidably mounted on the material conveying rail 15. The carrier 7 is located on the top surface of the corresponding trolley 16 and can be directly pushed by a cylinder to move the trolley step by step along the material conveying rail. The trolleys 16 drive the carrier 7 to move intermittently along the track, or the belt conveyor mechanism can drive the carrier to move continuously. Of course, the processing track and the block conveying track can also be a ring conveying mechanism. The processing track 1 is divided into a pressing block loading station area, a rotor assembly loading station area, a lever assembly station area and a pressing block unloading station area along the conveying direction. Each station area is equipped with a pressing block loading unit 3, a rotor assembly loading unit 4, a transmission lever assembly unit 5 and a pressing block unloading unit 6. The processing track 1 is provided with several carriers 7, and each carrier 7 has a workpiece cavity 71. The workpiece cavity 71 is divided into a knob cap receiving groove 711 for accommodating a knob cap in an inverted state and a cover positioning groove 712 for accommodating a cover in an inverted state. The two groove areas are designed according to the inverted posture of the workpiece and can limit the knob cap and the cover respectively. The knob cap, the cover and the track seat inside the cover constitute a cover pre-assembly assembly. The cover pre-assembly assembly moves along the processing track 1 with the carrier 7 and arrives at each work station in sequence to wait for operation. The conventional design of the briquette conveying track 2 is like a belt conveyor mechanism, used to carry the briquette 8 and convey the briquette 8 from the upstream return area 21 to the downstream loading area 22. The briquette 8 has a hollow cavity 81 that is vertically opened for the rotor assembly to pass through, and the hollow cavity 81 is provided with positioning pin avoidance grooves 82 on opposite sides. The pressing block feeding unit 3 is used to feed the pressing blocks 8 on the downstream feeding area 22 of the pressing block conveying track 2 to the carrier 7 in the pressing block feeding station area of ​​the processing track 1, so that the pressing blocks 8 are placed vertically on the track seat provided inside the upper cover carried by the carrier 7, and the inner peripheral wall of the pressing block 8 is flush with the inner peripheral wall of the track seat to form a vertically extending limiting surface 80. The upper end of the pressing block 8 is also exposed outside the upper cover. The pressing block has a certain weight and will not be lifted by the second positioning pin. Specifically, the downstream feeding area 22 of the pressing block conveying track 2 and the pressing block feeding station area of ​​the processing track 1 are both located below the pressing block feeding unit 3. The pressing block feeding unit 3 includes a first pressing block gripper 31, a first vertical sliding drive module 32 and a first horizontal sliding drive module 33. The moving module 33 has the first pressing block gripper connected to the power output end of the first vertical sliding drive module and the first vertical sliding drive module connected to the power output end of the first horizontal sliding drive module. The first pressing block gripper 31 is used to hold the pressing block 8 in the downstream loading area 22 of the pressing block conveying track 2. The first vertical sliding drive module 32 is used to drive the first pressing block gripper 31 to move the pressing block 8 vertically. The first horizontal sliding drive module 33 is used to drive the first pressing block gripper 31 to move the pressing block 8 horizontally, so as to realize the cross-track transfer of the pressing block 8 between the downstream loading area 22 of the pressing block conveying track 2 and the pressing block loading station area of ​​the processing track 1, and complete the automatic transfer operation of the pressing block from loading to processing station without manual placement of the pressing block. The rotor assembly loading unit 4 is used to load the rotor assembly onto the carrier 7 in the rotor assembly loading station area of ​​the processing track 1, so that the rotor assembly vertically passes through the hollow cavity 81 of the pressure block 8 on the carrier 7 in an inverted state and is placed inside the track seat. The second positioning pin of the rotor assembly abuts against the limiting surface 80 to prevent the end of the second positioning pin from warping upwards to the bottom surface of the track seat, ensuring that the assembly hole of the rotor seat aligns and communicates with the insertion hole of the upper cover. Specifically, the rotor assembly loading unit 4 includes a storage-type automatic loading and unloading device 41 and a first industrial robotic arm 42. The storage-type automatic loading and unloading device 41 is a conventional design, such as CN222664449U, a vertical storage-type automatic loading and unloading device, employing a stack lifting structure. The stacked material trays 43 have a plurality of rotor receiving slots 431 on their surface for accommodating rotor assemblies in an inverted state. The plurality of rotor receiving slots 431 can be arranged in an array, and the rotor receiving slots 431 individually limit the rotor assembly. A single material tray 43 can be automatically fed to the rotor picking station in sequence. The first industrial robotic arm 42 is equipped with a rotor gripper 421 at its execution end. The first industrial robotic arm is a multi-axis servo robotic arm, which can drive the rotor gripper to pick up a single rotor assembly with accurate posture from the material tray and transfer it to the corresponding position on the carrier cover to complete the assembly into the inner side of the track seat inside the cover. The high-precision positioning of the robotic arm ensures the accurate assembly position of the rotor assembly and avoids assembly failures caused by human alignment deviation. The transmission lever assembly unit 5 is used to feed the transmission levers to the carrier 7 in the lever assembly station area of ​​the processing track 1, so that the transmission levers are inverted and inserted into the assembly holes of the rotor seat and the insertion holes of the cover on the carrier 7, forming an insertion assembly with the knob cap; specifically, the transmission lever assembly unit 5 includes a lever feeding tray device 51, a second industrial robotic arm 52, a lever flipping and erecting mechanism 53, a lever conveying mechanism 54, and a lever detection mechanism 55; the lever feeding tray device 51 is a conventional design with a vibratory plate, which disperses several transmission levers by electromagnetic vibration; the execution end of the second industrial robotic arm 52 is equipped with a first lever gripper 521, which is used to hold the levers lying horizontally inside the lever feeding tray device 51. The transmission lever in its horizontal position is transported to the lever flipping and uprighting mechanism 53 by the second industrial robotic arm 52. The lever flipping and uprighting mechanism 53 includes a second lever gripper 531 and a flipping adjustment drive module 532. The second lever gripper 531 is connected to the power output end of the flipping adjustment drive module 532 and is used to grip the horizontally lying transmission lever. The flipping adjustment drive module is a rotary cylinder that can drive the second lever gripper and the gripped transmission lever to complete a 90-degree upward rotation around the horizontal axis, flipping and adjusting the originally horizontally lying transmission lever to a vertically inverted state. The lever transport mechanism 54 includes a third lever gripper 541, a rotary adjustment drive module 542, and a third vertical sliding drive module 543. The third horizontal sliding drive module 544 includes a third lever gripper 541 for holding an inverted, upright transmission lever; a rotation adjustment drive module 542 for rotating the third lever gripper 541 around a vertical axis to adjust the circumferential angle of the transmission lever; a third vertical sliding drive module 543 for driving the third lever gripper 541 to vertically raise and lower the transmission lever; and a third horizontal sliding drive module 544 for driving the third lever gripper 541 to horizontally slide the transmission lever, transporting the inverted, upright transmission lever above the corresponding carrier 7. The lever detection mechanism 55 includes a detection camera 551 and a detection reflection box 552. The detection reflection box 552 contains an inclined reflector 553. 2. A workpiece observation port 5521 is provided at the upper end, and a camera window 5522 is provided on the side wall. The detection camera 551 is a conventional structure, which is placed horizontally, and the lens is facing the reflector 553 through the camera window 5522. The detection reflection box 552 is located below the flipped second lever gripper 531, and the image of the transmission lever above the workpiece observation port 5521 is projected onto the reflector 553. Then, the detection camera 551 takes a picture of the transmission lever image reflected by the reflector 553 through the camera window 5522. Finally, the detection camera transmits the image signal to the host computer processing system for processing and recognition. The host computer processing system software is designed in a conventional way, and judges whether the circumferential angle of the transmission lever meets the assembly requirements through image analysis.

[0023] The briquetting unloading unit 6 is used to remove the briquetting blocks 8 from the inside of the upper cover of the carrier 7 in the briquetting unloading station area of ​​the processing track 1 and place them in the upstream return material area 21 of the briquetting conveying track 2. Specifically, the block unloading station area of ​​the processing track 1 and the upstream return area 21 of the block conveying track 2 are both located below the block unloading unit 6. The block unloading unit 6 includes a second block gripper 61, a second vertical sliding drive module 62, and a second horizontal sliding drive module 63. The second block gripper 61 is used to hold the block 8 in the block unloading station area of ​​the processing track 1. The second vertical sliding drive module 62 is used to drive the second block gripper 61 to move the block 8 vertically up and down. The second horizontal sliding drive module 63 is used to drive the second block gripper 61 to move the block 8 horizontally, so as to realize the cross-track transfer of the block 8 between the block unloading station area of ​​the processing track 1 and the upstream return area 21 of the block conveying track 2, and complete the unloading and recycling operation after the block assembly is completed. The block can be sent back to the downstream loading area for repeated use through the block conveying track.

[0024] Specifically, both the rotor assembly loading unit 4 and the transmission lever assembly unit 5 include a cover positioning and correction mechanism 9. The cover positioning and correction mechanism 9 includes a pair of cover abutment plates 91 and a plate sliding drive module 92 for driving the cover abutment plates to slide. The cover abutment plates 91 are connected to the power output end of the plate sliding drive module 92. The cover abutment plates 91 have positioning abutment surfaces 911 that are adapted to the corners of the outer wall of the cover. The plate sliding drive module 92 can drive the pair of cover abutment plates 91 to move closer or further away from each other. The positioning abutment surfaces 911 of the pair of cover abutment plates 91 abut against the two sides of the outer wall of the cover respectively to perform position positioning and correction of the cover placed on the carrier 7. Before assembly, the cover can be clamped first to correct and position the cover, which facilitates the subsequent loading and assembly of the rotor assembly and transmission lever.

[0025] 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.

[0026] The specific working principle is as follows: First, place the knob cap and the top cover in the corresponding positions of the workpiece cavity of the carrier in an inverted position. The top cover is equipped with a track seat, thus completing the initial loading of the top cover pre-assembled components. The mobile trolley drives the carrier to move intermittently along the processing track, so that the carrier first arrives at the briquetting and feeding station area. The first briquetting gripper of the briquetting and feeding unit picks up the briquetting block from the downstream feeding area of ​​the briquetting and feeding track. After the first horizontal sliding drive module and the first vertical sliding drive module are activated, the briquetting block is lowered onto the upper cover track seat of the carrier, completing the automatic feeding of the briquetting block. The carrier that has completed the pressing block feeding continues to move to the rotor assembly feeding station area. First, the sliding drive module of the upper cover positioning and correction mechanism in the rotor assembly feeding unit drives a pair of upper cover abutment plates to approach each other. The positioning abutment surfaces on them press against the two sides of the outer wall of the upper cover respectively, completing the correction and positioning of the upper cover position. Then, the first industrial robotic arm of the rotor assembly feeding unit drives the rotor gripper to take out a single positioned inverted rotor assembly from the material tray of the warehouse-type automatic loading and unloading equipment. The rotor assembly is placed vertically through the hollow cavity of the pressing block into the inner side of the track seat, so that the second positioning pin of the rotor assembly is abutted and limited by the limiting surface of the pressing block, ensuring that the assembly hole of the rotor seat and the insertion hole of the upper cover are accurately aligned, completing the automatic assembly of the rotor assembly. The carrier that has completed the rotor assembly continues to move to the lever assembly station area. Here, the upper cover position is re-corrected and positioned by the upper cover positioning and correction mechanism in the transmission lever assembly unit. Then, the feeding and assembly of the transmission lever begins: after the lever feeding tray equipment vibrates and disperses the transmission lever, the second industrial robotic arm drives the first lever gripper to pick up the transmission lever in its lying position and transport it to the lever flipping and uprighting mechanism. After the second lever gripper holds the transmission lever, the flipping and adjustment drive module drives it to complete a 90-degree flip, adjusting the transmission lever to a vertical position. In the inverted state, the detection camera of the lever detection mechanism then captures an image of the transmission lever through a reflector. The upper computer system analyzes and judges whether the posture of the transmission lever is qualified. Subsequently, the third lever gripper of the lever transport mechanism clamps the transmission lever, and the circumferential angle of the transmission lever is adjusted to the assembly requirements by the rotation adjustment drive module. Then, through the action of the third horizontal sliding drive module and the third vertical sliding drive module, the transmission lever is transported to the top of the carrier, and lowered through the assembly hole of the rotor seat and the insertion hole of the top cover to complete the insertion assembly with the knob cap below. After completing the transmission lever assembly, the carrier moves to the block unloading station area. The second block gripper of the block unloading unit holds the block inside the cover. Through the action of the second vertical sliding drive module and the second horizontal sliding drive module, the block is transferred to the upstream return area of ​​the block conveying track. The block is sent back to the downstream loading area along the block conveying track for recycling. The assembled knob switch cover assembly remains on the carrier and can be unloaded from the end of the processing track, completing the entire rotor assembly process.
