Technical Field

[0001] This invention relates to the field of production line technology, and in particular to an assembly production line. Background Technology

[0002] A DCM signal receiver assembly is an integrated signal processing system that integrates DCM functions for a specific field. It typically includes core components such as antennas / sensors, signal capture units, demodulation / decoding modules, and control circuits. It can complete the entire process of signal reception, conversion, processing, and output. In the automotive field, DCM signal receivers are mainly used as data communication module receivers or door control modules.

[0003] The current DCM signal receiver assembly for automobiles is generally assembled by manually removing, placing, and assembling four parts, and then tightening them with tools. The entire assembly process requires manual intervention, which results in wasted working hours, low production efficiency, and low quality assurance.

[0004] Therefore, it is necessary to provide a new assembly line to solve the above-mentioned technical problems. Summary of the Invention

[0023] To achieve the above objectives, please refer to Figure 1This invention proposes an assembly production line 100, comprising a control unit 1, a first shelf 2, a second shelf 3, a third shelf 4, a flipping device 5, a first conveyor line 6, a second conveyor line 7, a first vision unit 8, a first robot 9, a second robot 11, and a third robot 12. The first shelf 2 is used to place side parts 101, the second shelf 3 is used to place the main body part 102, and the third shelf 4 is used to place the part assembly 103 composed of the side parts 101 and the main body part 102. The flipping device 5 is used to flip the side parts 101 to their front side. The first conveyor line 6 is used to transport the side parts 101. The second conveyor line 7 is equipped with a transport fixture 71, which is used to fix the side parts 101 and the main body part 102. 2. The first vision component 8 is used to detect the placement posture of the two side parts 101 in the first shelf 2. The first robot is used to transport the two side parts 101 to the flipping device 5 or the first conveyor line 6. The second robot 11 is used to transport the main body part 102 in the second shelf 3 to the transport fixture 71 and to transport the two side parts 101 on the first conveyor line 6 to the transport fixture 71. The third robot 12 is used to tighten the two side parts 101 to the main body part 102 to form the part assembly 103 and to transport the part assembly 103 to the third shelf 4. The flipping device 5, the first conveyor line 6, the second conveyor line 7, the first vision component 8, the first robot 9, the second robot 11 and the third robot 12 are all signal connected to the control component 1. Specifically, the first vision component 8 detects the placement posture of the two side parts 101 in the first shelf 2, and then the first vision component 8 transmits the detected information to the control component 1. When the two side parts 101 are detected to be in a frontal posture, the control component 1 controls the first robot to transfer the two side parts 101 in the frontal posture to the first conveyor line 6. When the two side parts 101 are detected to be in a reverse posture, the control component 1 controls the first robot to transfer the two side parts 101 in the reverse posture to the flipping device 5. After the flipping device 5 flips the two side parts 101 in the reverse posture to the frontal posture, the control component 1 then controls the first robot to flip them to the frontal posture. The two side parts 101 are then transferred to the first conveyor line 6. The first conveyor line 6 transports the two side parts 101 in the frontal position to one end near the second conveyor line 7. The second robot 11 transfers the main body part 102 on the second shelf 3 to the transport fixture 71 of the second conveyor line 7, and then transfers the two side parts 101 on the first conveyor line 6 to the transport fixture 71 and fixes them to the main body part 102. Then the second conveyor line 7 transports the transport fixture 71 to the working range of the third robot 12. The third robot 12 grabs the bolts and tightens the two side parts 101 and the main body part 102 to form the part assembly 103, and then transfers it to the third shelf 4.The control unit 1 serves as the core, enabling coordinated control of all components. The first vision unit 8 provides posture detection data to guide the first robot in precise sorting. The flipping device 5 addresses the posture adjustment needs of reverse-side parts. The transport fixture 71 ensures the stable fixation of parts on the second conveyor line 7. Each robot completes material transfer and assembly processes through clamping or tightening actions. The shelving system enables the categorized storage of different types of parts. This invention replaces manual labor with fully automated operation, eliminating wasted working hours and potential risks of musculoskeletal injuries, effectively improving production efficiency and product quality assurance. Simultaneously, the coordinated operation of all components ensures the stability and accuracy of the assembly process.

[0024] Please see Figures 9 to 11In one embodiment, the flipping device 5 includes a mounting frame 51, a driving component 52, a first bracket 53, a second bracket 54, and a magnetic component 55. The driving component 52 is mounted on the mounting frame 51, the first bracket 53 is connected to the rotation shaft of the driving component 52, the second bracket 54 is mounted on the mounting frame 51, and the magnetic component 55 is disposed at the bottom of the first bracket 53. The driving component 52 is used to drive the first bracket 53 to rotate above the second bracket 54, and the placement surface of the first bracket 53 faces the placement surface of the second bracket 54. When the first robot places the two reverse-facing parts 101 on the placement surface of the first support 53, the control unit 1 controls the magnetic suction component 55 to attract the two parts 101 placed on the placement surface of the first support 53. Then, the control unit 1 activates the drive component 52, driving the rotation axis of the drive component 52 to rotate. This causes the first support 53 to rotate towards the second support 54. The control unit 1 sets the operation time of the drive component 52 and the magnetic suction component 55 to be the same. The drive component 52 and the magnetic suction component 55 operate simultaneously. After the preset rotation time of the drive component 52, when the first support 53 rotates to above the second support 54, the drive component 52 stops operating. At this time, the placement surface of the first support 53 faces the placement surface of the second support 54. Simultaneously, the magnetic suction component 55 will also operate for the same amount of time, that is, when the top of the first support 53 faces the top of the second support 54, the magnetic suction component 55 will also stop operating. When the magnetic component 55 loses its adsorption capacity, the two parts 101 on the placement surface of the first support 53 will fall to the placement surface of the second support 54 due to gravity. The two parts 101 that were originally in the reverse position on the first support 53 will become the forward position on the second support 54, thus completing the flipping of the two parts 101. A period of silence is set in the control component 1. When the first support 53 is in the set position, after this period of silence, the two parts 101 control the rotation axis of the drive component 52 to rotate in the opposite direction, so that the first support 53 returns to its original position, and then the above steps are repeated. In this embodiment, the control component 1 coordinates the actions of the magnetic component 55 and the drive component 52 to realize the automatic flipping of parts. The magnetic adsorption ensures that the parts are stable and do not slip during the flipping process. The flipping process reduces manual intervention and improves the flipping efficiency. At the same time, the simple structure greatly reduces the production cost and space occupation compared with flipping by a dedicated robot.

[0025] Please see Figures 9 to 11Furthermore, the first support 53 has a first receiving groove 531, and the second support 54 has a second receiving groove 541. Both the first receiving groove 531 and the second receiving groove 541 are used to place the parts 101 on both sides. The first receiving groove 531 at the top of the first support 53 and the second receiving groove 541 at the top of the second support 54 can accurately adapt to the shape and size of the parts, assisting the electromagnetic adsorption mechanism to fix the parts more stably, effectively preventing the parts from shifting or slipping during the flipping process, and improving the reliability of the flipping action. At the same time, the positioning function of the groove ensures the consistency of the part's position before and after flipping, and with the precise angle control driven by the cylinder, it further ensures the accuracy of the flipping posture. In addition, the design of the first receiving groove 531 and the second receiving groove 541 of different specifications can flexibly adapt to parts of various shapes, enhance the compatibility of the tooling with different products, and help improve the flexibility and efficiency of the production line.

[0026] Please see Figures 9 to 11In one embodiment, the flipping device 5 further includes a first position sensor 56 and a second position sensor 57. Both the first position sensor 56 and the second position sensor 57 are mounted on the mounting bracket 51. The first position sensor 56 is used to detect whether there are two side parts 101 on the placement surface of the first bracket 53, and the second position sensor 57 is used to detect whether there are two side parts 101 on the placement surface of the second bracket 54. When the two side parts 101 are placed into the first receiving groove 531 at the top of the first bracket 53, the first position sensor 56 mounted on the mounting bracket 51 detects the presence of the two side parts 101 through the first detection opening 532542 communicating with the first receiving groove 531, and then sends a signal back to the control component 1. After receiving the signal, the control component 1 controls the driving component 52 and the magnetic suction component 55 to run for the same amount of time. At the same time, the magnetic suction component 55 and the driving component 52 are driven to run. The magnetic suction component 55 attracts the two side parts 101, and at the same time, the rotation shaft of the driving component 52 rotates, causing the first bracket 53 to flip toward the second bracket 54 to the designated position. At this time, the driving component... When component 52 and magnetic component 55 stop operating simultaneously, the first support 53 rotates to above the second support 54, the first receiving groove 531 faces the second receiving groove 541, the magnetic component 55 stops operating and loses its adsorption capacity. Thus, the components 101 on both sides in the first receiving groove 531 will fall into the second receiving groove 541 due to gravity, completing the flipping of the components 101. Simultaneously, when the second position sensor 57 detects the presence of a component through the second detection opening connected to the second receiving groove 541, the controller drives the rotating shaft of the drive component 52 to rotate in the opposite direction, causing the first support 53 to return to its original position. Then, the above steps are repeated. The first position sensor 56 and the second position sensor 57 accurately detect the status of the components in the first receiving groove 531 and the second receiving groove 541 through the first detection opening 532 and the second detection opening, respectively, realizing automatic triggering and completion confirmation of the flipping process, forming a closed-loop control, further reducing manual intervention.

[0027] Please see Figures 2 to 4In one embodiment, the first robot includes a first gripping component 91, a first cylinder 92, an electromagnet 93, a second cylinder 94, and a first adsorption component 95. The extension shaft of the first cylinder 92 is connected to the electromagnet 93, and the extension shaft of the second cylinder 94 is connected to the first adsorption component 95. The first gripping component 91 is used to grip the empty box 104 on the first shelf 2, and the first adsorption component 95 is used to adsorb the two side parts 101 in the first shelf 2. When it is necessary to grasp the two side parts 101 in the front orientation of the first shelf 2, the control unit 1 controls the first suction member 95 of the first robot to move above the first shelf 2. Then, the control unit 1 drives the second cylinder 94 to operate, and the extension shaft of the second drive extends, pushing the first suction member 95 towards the first shelf 2, so that the first suction member 95 adsorbs the two side parts 101 in the front orientation of the first shelf 2. Then, the extension shaft of the second drive retracts, and the control unit 1 drives the first robot to move and place the two side parts 101 adsorbed by the first suction member 95 onto the first conveyor line 6. When it is necessary to grasp the two side parts 101 in the reverse orientation of the first shelf 2, the control unit 1 controls the first suction member 95 of the first robot to move above the first shelf 2. Then, the control unit 1 drives the second cylinder 94 to operate, and the extension shaft of the second drive extends, pushing the first suction member 95 towards the first shelf 2, so that the first suction member 95 adsorbs the two side parts 101 in the reverse orientation of the first shelf 2. Then, the extension shaft of the second drive retracts, and ... retracts, and the extension shaft of the second drive retracts, and the extension shaft of the second drive retracts, and the extension shaft of the second drive retracts, and the extension shaft of the second drive retracts, and the extension shaft of the second drive retracts, and the extension shaft of the second drive retracts, and the extension shaft of the second drive retract A robot places the two side parts 101 adsorbed by the first adsorption component 95 onto the flipping device 5. After the flipping device 5 completes its operation, the control unit 1 drives the first robot to place the two side parts 101 adsorbed by the first adsorption component 95 onto the first conveyor line 6. When the first vision component 8 encounters a posture of the two side parts 101 that cannot be recognized, the control unit 1 drives the first cylinder 92 to operate. The extension shaft of the first drive cylinder extends, driving the electromagnet 93 to move towards the first shelf 2, so that the electromagnet 93 contacts the unrecognizable two side parts 101. The electromagnet 93 adsorbs the unrecognizable two side parts 101. Then the extension shaft of the first cylinder 92 retracts, and then the extension shaft of the first cylinder 92 extends again. The control unit 1 controls the electromagnet 93 to stop operating, thus enabling it to have adsorption capacity. This adjusts the placement posture of the two side parts 101 again, so that it meets the recognition conditions and supports the adsorption step of the first adsorption component 95. When there are no parts in the first shelf 2, the first robot uses the first gripping component 91 to grip the empty box 104 to complete the recycling.

[0028] The first cylinder 92 and the electromagnet 93 work together to actively adjust the posture of the parts. The second cylinder 94 and the first adsorption component 95 cooperate to accurately adsorb the parts 101 on both sides. The first gripping component 91 specifically grips and retrieves the empty box 104. Through mechanical drive and functional coordination, these components form an automated mechanism for parts sorting and empty box 104 processing. The beneficial effects of this embodiment are significant: by replacing manual sorting and empty box 104 retrieval with automated operation, the waste of time and potential health risks associated with manual labor are eliminated; the posture adjustment mechanism of the electromagnet 93 improves the success rate and stability of parts picking, effectively increasing production efficiency and operational accuracy.

[0029] Furthermore, the bottom of the flipping device 5 is provided with multiple support feet 58, which are arranged in a rectangular pattern. This rectangular arrangement of support feet 58 provides a stable support base for the flipping device 5. The symmetrical rectangular structure ensures even force distribution, effectively distributing the overall weight of the tooling and the dynamic load during the flipping process, preventing tilting or swaying of the tooling, and ensuring the accuracy of the angle and the stability of the part flipping when driven by the cylinder. Simultaneously, the design of the bottom support feet 58 reduces direct contact between the flipping device 5 and the ground, reducing wear, extending the tooling's service life, and improving the overall structural reliability.

[0030] Furthermore, a threaded hole is formed at the bottom of the flipping device 5. The support foot 58 includes a connecting rod 581 and a support pad 582 installed at one end of the connecting rod 581. The connecting rod 581 has a threaded section 581a, which is threadedly connected to the threaded hole. A locking nut 59 is provided on the threaded section 581a, which is used to abut against the bottom of the flipping device 5. When installing the support foot 58, the threaded section 581a of the connecting rod 581 of the support foot 58 is screwed into the threaded hole at the bottom of the flipping device 5. The screwing depth of the connecting rod 581 is adjusted according to actual needs to adjust the support height. After the height is appropriate, the locking nut 59 on the threaded section 581a is tightened to make it tightly abut against the bottom of the flipping device 5, thus completing the fixed installation of the support foot 58. The threaded connection allows for flexible height adjustment of the support foot 58, facilitating quick leveling of the tilting device 5 and adapting to the level requirements of different ground surfaces or workstations. The locking nut 59 effectively prevents the connecting rod 581 from loosening during the operation of the tilting device 5, ensuring the stability of the support structure. The support pad 582 increases the contact area with the ground, distributing the weight of the tooling and dynamic loads, and reducing ground wear. The overall structure is easy to install, disassemble, and maintain, improving the adaptability and reliability of the tilting device 5.

[0031] Please see Figures 5 to 8In one embodiment, the second robot 11 includes a second vision component, a second adsorption component 112, and a second gripping component 113. Multiple second adsorption components 112 are spaced apart and are used to adsorb the main body parts 102 in the second shelf 3. The second vision component detects the posture of the main body parts 102 in the second shelf 3. The second gripping component 113 grips empty boxes 104 on the second shelf 3. The second vision component detects the posture of the main body parts 102 in the second shelf 3. The second robot 11 uses the multiple spaced-apart second adsorption components 112 to adsorb main body parts 102 with the required posture and transfers them to the transport fixture 71 for fixation. When there are no main body parts 102 in the second shelf 3, the second robot 11 uses the second gripping component 113 to grip the empty box 104 to complete the retrieval. The second vision component provides precise detection data of the posture of the main part 102, providing a positioning basis for the adsorption operation of the second adsorption component 112. Multiple spaced second adsorption components 112 improve the adsorption stability of the main part 102 through optimized contact layout. The second gripping component 113 is designed for the empty box 104 recycling scenario, realizing automated gripping of the empty box 104. All components work together to form an automated process of orderly picking of the main part 102 and recycling of the empty box 104. By replacing manual picking of the main part 102 and recycling of the empty box 104 with automated operation, the waste of time and potential health risks associated with manual labor are eliminated, improving production efficiency and quality assurance. The stable adsorption of multiple adsorption components and the precise detection of the second vision ensure the success rate and accuracy of picking the main part 102, while the automatic recycling mechanism of the empty box 104 improves operational continuity.

[0032] Please see Figure 12In one embodiment, the transport fixture 71 includes a rotary cylinder 711 and a clamping component 712. The rotary cylinder 711 is mounted on the second conveyor line 7. The clamping component includes a mounting plate 712a and two clamping cylinders 712b. Both clamping cylinders 712b are mounted on the mounting plate 712a. The mounting plate 712a is mounted on the rotary shaft of the rotary cylinder 711. The extension shaft of the clamping cylinder 712b is provided with a clamping member 712c. The mounting plate 712a is provided with a support member 712d, which is used to place the main body part 102. The extension shafts of the two clamping cylinders 712b extend in opposite directions to drive the two clamping members 712c to move closer to each other and clamp the two side parts 101 onto the main body part 102. A rotary cylinder 711 is installed on the second conveyor line 7. Its rotating shaft drives the mounting plate 712a and the supporting member 712d above it, as well as the clamping components, to move in tandem. After the main part 102 is positioned on the supporting member 712d, two clamping cylinders 712b extending in opposite directions drive the clamping member 712c to move closer together, clamping and fixing the parts 101 on both sides onto the main part 102. The rotary cylinder 711 can adjust the angle of the mounting plate 712a according to the process requirements to adapt to subsequent operations. The rotary cylinder 711 provides the power for angle adjustment of the tooling, the supporting member 712d achieves precise positioning of the main part 102, and the two clamping cylinders 712b arranged in opposite directions form a stable clamping force through the opposing movement of the clamping member 712c, ensuring a tight connection between the parts 101 on both sides and the main part 102. Through the coordinated cooperation of the mechanical structure, each component realizes the functions of positioning, clamping, and posture adjustment during the assembly process. The transport fixture 71 replaces manual operation with automated positioning, clamping and angle adjustment, eliminating the time wasted on manual fixing of parts, improving the accuracy and stability of parts assembly, ensuring product quality, and adapting to the collaborative needs of automated production lines.

[0033] Please see Figure 12Furthermore, a first limiting plate 712e and two second limiting plates 712f are formed on the support member 712d. The two second limiting plates 712f are arranged opposite each other and are located at both ends of the first limiting plate 712e. The first limiting plate 712e and the two second limiting plates 712f surround to form a groove 712g, which is used to engage with the main body part 102. When the main part 102 is transported to the working area of ​​the fixture component, it first completes the initial snap-fit ​​positioning through the groove 712g formed by the first limiting plate 712e and two second limiting plates 712f on the support member 712d, so that the bottom of the main part 102 is precisely fitted into the groove 712g, ensuring the stability of the initial posture; then, the two clamping cylinders 712b on the mounting plate 712a are activated simultaneously, and the extension shafts extend in opposite directions, driving the end clamping members 712c to move closer to each other, fixing the two side parts 101 onto the main part 102; then, with the cooperation of the second conveyor line 7, the assembled parts are precisely transported to the tightening work area of ​​the third robot 12 or adjusted to a suitable tightening angle; after the tightening process is completed, the extension shafts of the clamping cylinders 712b retract, the clamping members 712c move away from each other, and the part assembly 103 is released from the lateral clamp and taken out from the groove 712g, in conjunction with the subsequent finished product transfer. The 712g groove snap-fit ​​structure can accurately pre-position the main part 102, effectively preventing the main part 102 from shifting or rotating during conveying, angle adjustment and tightening, and greatly improving the positioning accuracy.

[0034] Please see Figure 12Furthermore, the fixture component also includes a third drive cylinder 712h, which is positioned opposite to the support member 712d. The extension shaft of the third drive cylinder 712h is used to abut against the side of the main body part 102 away from the first limiting plate 712e. When the main body part 102 is transported to the working area of ​​the fixture component, it first completes the initial snap-fit ​​positioning through the groove 712g on the support member 712d surrounded by the first limiting plate 712e and two second limiting plates 712f, providing basic posture protection for the main body part 102. Then, the extension shaft of the drive cylinder, which is positioned opposite to the support member 712d, moves forward and precisely abuts against the side of the main body part 102 away from the first limiting plate 712e, forming a stable clamping in the front-back direction. Subsequently, the two clamps on the mounting plate 712a... Cylinder 712b starts synchronously, and the extension shaft extends in the opposite direction, driving clamping member 712c to fix and clamp the two side parts 101 and the main body part 102 from the side. Then, the second conveyor line 7 accurately delivers the clamped parts to the tightening operation area of ​​the third robot 12, and adjusts them to the appropriate angle with the rotation mechanism to complete the tightening process. After the process is completed, the third drive cylinder 712h retracts to release the front and rear clamping, and the clamping cylinder 712b retracts to release the part assembly 103, and the part assembly 103 is removed from the fixed structure for subsequent transfer. The addition of the third drive cylinder 712h fills the gap that the overall part is prone to displacement in the front and rear direction when only the groove 712g and the side clamping are used. It is especially suitable for long strip, thin-walled or heavy overall parts, and effectively prevents the workpiece from axial movement or posture deviation during the conveying, angle adjustment and tightening process.

[0035] Please see Figure 12 Furthermore, the fixture component also includes a positioning sensor 712i, which is mounted on the mounting plate 712a. When the overall part and the two side parts 101 are both placed on the support 712d, the positioning sensor 712i on the mounting plate 712a detects that the preset clamping position has been reached and immediately sends a positioning signal to the system control component 1. After receiving the signal, the control component 1 sequentially activates the drive cylinder to extend its shaft to abut the side of the workpiece away from the first limit plate 712e, and the clamping cylinder 712b drives the clamping component 712c to clamp symmetrically from the side. The addition of the positioning sensor 712i realizes the automated detection and action triggering of workpiece positioning, replacing manual judgment, greatly shortening the waiting time at the workstation, and improving the overall operation efficiency.

[0036] Please see Figure 3 and Figure 14In one embodiment, the third robot 12 includes a third adsorption member 121, a third gripping member 122, and a tightening member 123. The third robot 12 uses the tightening member 123 to tighten bolts through the two side parts 101 to the main body part 102 to form a part assembly 103. The third adsorption member 121 is used to adsorb the part assembly 103. The third robot 12 uses the third gripping member 122 to grip and transport the empty box 104 in the empty box 104 rack to the third shelf 4. The bolts are passed through the two side parts 101 by the tightening component 123 and locked to the main part 102 to form the part assembly 103. The part assembly 103 is then transferred by the third attachment. The empty box 104 in the empty box 104 rack is then picked up by the third clamping component 122 and transported to the third shelf 4. The tightening component 123 achieves a fixed connection between the parts through mechanical tightening action. The third adsorption component 121 stably grips the part assembly 103 with adsorption force. The third clamping component 122 completes the automated transfer of the empty box 104 through the clamping structure. The integrated design of each component is adapted to multiple operation scenarios.

[0037] Furthermore, the tightening component 123 includes a tightening shaft and a sleeve, which are detachably connected. This allows for the selection of different sleeves and corresponding bolts according to different locking requirements, thereby increasing the applicability of the assembly line 100.

[0038] Furthermore, the first gripping component 91, the second gripping component 113, and the third gripping component 122 each include a linear cylinder 105 and a first gripping block 106. The sliding end of the linear cylinder 105 is connected to the second gripping block 105a. The first gripping block 106 and the linear cylinder 105 are both installed on the corresponding robot. The first gripping block 106 and the second gripping block 105a are arranged opposite to each other. The linear cylinder 105 is used to drive the second gripping block 105a to move toward or away from the first gripping block 106. First, the first clamping block 106 is fixedly installed at the designated position on the corresponding robot. Then, the linear cylinder 105 is installed on the corresponding robot, ensuring that its sliding end is opposite to the first clamping block 106. Subsequently, the second clamping block 105a is connected to the sliding end of the linear cylinder 105 to complete the mechanical assembly. The sliding end of the linear cylinder 105 is driven to move the second clamping block 105a closer to the first clamping block 106 to clamp the empty box 104, or to move away from the empty box 104 to release it. This, combined with the robot's movement trajectory, enables sorting, handling, and other operations. The stable drive of the linear cylinder 105 makes the clamping force precise and controllable, adapting to the needs of workpieces of different sizes.

[0039] Furthermore, the first clamping block 106 has a first slot 106a, and the second clamping block 105a has a second slot 105b. The first slot 106a and the second slot 105b are respectively used to engage with the slots on the empty box 104. The robotic arm moves to the position of the empty box 104, aligning the slots on the empty box 104 with the first slot 106a of the first clamping block 106 and the second slot 105b of the second clamping block 105a. The linear cylinder 105 drives the second clamping block 105a to move towards the first clamping block 106, using the two grooves 712g to engage with the workpiece to achieve stable clamping. Subsequently, the robot performs handling, sorting, and other operations according to a preset trajectory. After the operation is completed, the linear cylinder 105 drives the second clamping block 105a to open again, releasing the workpiece and resetting it. The engaging design of the first and second slots 105b greatly improves the stability of workpiece clamping and effectively prevents regular-shaped workpieces from slipping or shifting during handling.

[0040] Please see Figure 6 and Figure 13 In one embodiment, both the second robot 11 and the third robot 12 are equipped with wheels 107. The wheels 107 give the second robot 11 and the third robot 12 flexible mobility, enabling them to quickly adjust their working positions according to changes in production rhythm or process requirements, support program scheduling to carry out multi-station operations, and maximize flexible production. At the same time, the mobility, combined with the robot's multi-functional grippers, further expands the robot's applicability in sorting and packaging automation scenarios, improves the efficiency of gripper sharing and standardization, reduces equipment idle waste, and helps reduce costs and increase efficiency.

[0041] Please see Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 13 and Figure 14 In one embodiment, the first robot, the second robot 11, and the third robot 12 are all equipped with air pressure detectors 108. The three air pressure detectors 108 are used to detect the adsorption air pressure of the first adsorption element 95, the second adsorption element 112, and the third adsorption element 121, respectively. The air pressure detectors 108 on the first robot, the second robot 11, and the third robot 12 detect the adsorption air pressure of the first adsorption element 95, the second adsorption element 112, and the third adsorption element 121 in real time. By accurately monitoring the adsorption air pressure, it is possible to determine in real time whether the adsorption of the adsorption element on the main part 102, the Kanban, the dust cover, or the part assembly 103, etc., is firm, effectively avoiding the problem of target objects falling, operation interruption, or quality damage caused by unstable adsorption; improving the success rate of automated links such as disordered picking, Kanban recycling, dust cover handling, and part assembly 103 transfer, reducing the waste of time caused by adsorption failure; and ensuring the stability and reliability of the entire sorting and packaging process.

[0042] In one embodiment, the bottom of the first shelf 2, the second shelf 3, and the third shelf 4 are all equipped with casters 109. The casters 109 give the shelves flexible movement capabilities, allowing the shelf position or spacing to be adjusted according to production needs. This effectively alleviates the problem of physical component boxes on inclined shelves being squeezed by their own weight on the boxes at the retrieval end, and avoids false collision detection alarms when the robot is recovering empty boxes 104, which could lead to operation failure. This significantly improves the success rate of empty box 104 recovery. At the same time, the flexible movement of the shelves adapts to flexible production needs. After the cycle time changes, the shelf layout can be quickly adjusted to cooperate with the robot operation regulated by the program, enhancing the versatility and adaptability of the production line.

[0043] Furthermore, one end of the second robot 11 is provided with a male switching disk 114, the male switching disk 114 is provided with a magnetic alignment component 114c, a first air passage is formed in the male switching disk 114, a first mounting hole 114a is formed at the end of the male switching disk 114 away from the second robot 11, the first mounting hole 114a is connected to the first air passage, a protrusion 114b is slidably provided in the first mounting hole 114a, the protrusion 114b can extend out of the first mounting hole 114a; the second robot 11 also includes a body, the second vision component, the second adsorption component 112 and the second gripping component 113 are all provided on the body, a female switching disk 115 is provided on the body, the female switching disk 115 includes a magnetic engagement component 115a corresponding to the magnetic alignment component 114c, a second air passage is formed in the female switching disk 115, a second mounting hole 115b is formed at the end of the female switching disk 115 away from the body, the second mounting hole 115b is connected to the second air passage. The magnetic alignment component 114c built into the male switching plate 114 and the magnetic engagement component 115a of the female switching plate 115 are automatically and precisely aligned by magnetic attraction, ensuring that the first mounting hole 114a of the male switching plate 114 and the second mounting hole 115b of the female switching plate 115 are coaxial. The control component 1 sends a signal to the external air supply component, which supplies air to the first air passage of the male switching plate 114, pushing the protrusion 114b in the first mounting hole 114a to extend and engage with the second mounting hole 115b of the female switching plate 115. Simultaneously, negative pressure is created by evacuating the second air path, further reinforcing the engagement between the protrusion 114b and the second mounting hole 115b, thus achieving a stable lock on the male-female switching disc 115. When changing the clamp, the control unit adjusts the air path state of the air supply component, evacuating the first air path to retract the protrusion 114b into the first mounting hole 114a, releasing the engagement. At the same time, the second air path is supplied with air to balance the pressure, and the magnetic attraction between the magnetic alignment component 114c and the magnetic mating component 115a disappears, allowing for quick separation of the male-female switching disc 115 and completion of the clamp replacement. Magnetic alignment ensures docking accuracy, and air path drive enables the extension and retraction of the protrusion 114b. Combined with the intelligent control of the air path state by the control unit, tool-free switching can be completed in seconds, effectively solving the problems of long switching time and poor compatibility in traditional clamps.

[0044] Furthermore, there are multiple first mounting holes 114a, which are circumferentially distributed. The number of second mounting holes 115b is equal to the number of first mounting holes 114a, and they are set one-to-one. Each first mounting hole 114a has a slidably disposed protrusion 114b. The circumferentially distributed multi-point snap-fit ​​structure makes the male and female switching disc 115 connection more evenly stressed, significantly improving the structural stability and torsional resistance of the connection between the fixture and the robotic arm, and adapting to torque requirements in various scenarios such as tightening and handling. Secondly, the circumferential distribution design, in conjunction with the magnetic alignment mechanism, further ensures coaxiality and accuracy during docking, reducing alignment deviation. Thirdly, the pneumatic drive of all protrusions 114b extends or retracts synchronously, achieving stable locking at multiple points while maintaining the high efficiency of tool-free switching in seconds. Finally, this structure supports the cross-scenario universality of multi-functional fixtures, meets the standardization and common design goals, effectively solves the defects of unstable connection and low switching efficiency of traditional fixtures, and helps to significantly reduce the recovery time of production line anomalies.

[0045] Furthermore, the first suction component 95, the second suction component 112, and the third suction component 121 are all vacuum suction cups. Vacuum suction cups can stably adsorb various parts, supporting the robot to complete various tasks. Vacuum suction cups rely on negative pressure to adhere to the workpiece surface, eliminating the need for clamps of specific shapes. They can cover flat / curved surfaces, regular / irregular surfaces, and rigid / flexible workpieces, and are suitable for various materials such as metal, glass, plastic, wood, and paper.
