Description

TECHNICAL FIELD

[0001] The present application relates to the rivet machine equipment technical field, especially to a rivet system. BACKGROUND

[0002] The rivet machine needs to place a gasket on the lower die before riveting the workpiece. Currently, the production operator is responsible for placing the gasket on the lower die. The rivet system includes multiple processes, which are complex and need to be handled by multiple operators, resulting in waste of manpower, increased cost, and low efficiency of manual operation. The production speed is unstable. Before riveting the rivet machine, the operator needs to assemble the workpiece and then put it into the rivet machine for riveting. This process is complicated and may cause injury if the operator is not focused, and the operation safety is low. SUMMARY

[0003] The present application aims to at least solve one of the technical problems in the prior art. To this end, the present application provides a rivet system, which can be automatically operated, saving manpower, improving safety and operation efficiency.

[0004] The rivet system according to the embodiment of the present application comprises a fixing table, a rotating table, a gasket feeding machine, a gasket detection machine, a workpiece assembly feeding machine, a riveting machine, and an ejection machine. The fixing table has multiple stations, including a gasket feeding station, a gasket detection station, a workpiece feeding station, and a riveting station. The rotating table is rotatably arranged on the fixing table, and the multiple stations are distributed in a central symmetry around the rotating axis of the rotating table. The rotating table is provided with at least one positioning die, and the rotating table drives the positioning die to reach the multiple stations in turn when rotating. The gasket feeding machine is used to feed gaskets to the positioning die at the gasket feeding station. The gasket detection machine is used to detect whether there is a gasket on the positioning die at the gasket detection station. The workpiece assembly feeding machine is used to assemble at least two workpieces into a workpiece group and feed the assembled workpiece group to the positioning die at the workpiece feeding station. The riveting machine is arranged on the fixing table and is used to rivet the workpiece group and the gasket on the positioning die at the riveting station. The ejection machine is used to separate the riveted workpiece group from the positioning die at the riveting station and move it out of the rotating table.

[0005] According to an embodiment of the present invention, the riveting system, by sequentially arranging a gasket feeding machine, a gasket inspection machine, a workpiece assembly feeding machine, a riveting machine, and a discharge machine on the outer periphery of the turntable, can operate according to the riveting system's procedures. By setting the operation mode of the gasket feeding machine, gasket inspection machine, workpiece assembly feeding machine, riveting machine, and discharge machine to automatic operation, it can automatically place gaskets and detect their presence, and can also automatically assemble workpieces and rivet the assembled workpieces to the gaskets. The entire process requires no manual operation, saving manpower, avoiding work-related injuries caused by manual operation, and improving safety. The efficiency of automatic operation is higher than that of manual operation, and the accuracy and stability of automatic operation are also higher, thus improving product quality.

[0006] In some embodiments, the gasket feeding machine includes: a first base frame, a gasket vibratory feeder, and a movable feeding component. The first base frame is mounted on the fixed platform. The discharge end of the gasket vibratory feeder is disposed adjacent to the first base frame. The movable feeding component is movably mounted on the first base frame and is equipped with a suction nozzle. The movable feeding component can move the suction nozzle to the discharge end of the gasket vibratory feeder to pick up the gasket, and can also move the suction nozzle above the positioning mold to release the gasket. In this way, the gasket vibrated from the gasket vibratory feeder can be automatically picked up and moved above the positioning mold to place the gasket on the positioning mold, realizing the automatic gasket feeding function of the gasket feeding machine without manual operation, saving manpower.

[0007] Specifically, the gasket feeding machine further includes: a first guide rail mounted on the first base frame, a first slider mating on the first guide rail, and a first cylinder connected to the first slider. The moving material-picking component is connected to the first slider. By providing the first guide rail and the first slider, and by connecting the first cylinder between the first slider and the moving material-picking component, the position of the moving material-picking component can be adjusted, ensuring the accuracy of its movement direction and thus ensuring that the moving material-picking component can smoothly pick up and place gaskets.

[0008] Furthermore, the gasket inspection machine is mounted on the fixed platform, and includes a laser displacement sensor for irradiating the positioning mold. The laser displacement sensor has high detection accuracy and can detect without contact with the object being tested. Positioning the laser displacement sensor at the top of the gasket inspection machine and directing it towards the positioning mold ensures that the laser displacement sensor can fully detect the entire range of the positioning mold, resulting in higher accuracy of the detected data and improved detection precision.

[0009] In some embodiments, the at least two workpieces include a first workpiece and a second workpiece. The workpiece assembly and unloading machine includes: an assembly table, a workpiece vibratory feeder, a magazine, an assembly motion assembly, and a transfer robot. The assembly table is provided with a first placement position, a second placement position, and an assembly position. The discharge end of the workpiece vibratory feeder is connected to the first placement position to place the first workpiece onto the first placement position. The magazine is disposed on the assembly table, and the discharge end of the magazine faces the second placement position to place the second workpiece onto the second placement position. The assembly motion assembly is disposed on the assembly table and is used to transfer the first workpiece from the first placement position and the second workpiece from the second placement position to the assembly position, so that the first workpiece and the second workpiece form the workpiece group at the assembly position. The transfer robot is disposed on the fixed table, and the actuator of the transfer robot is movable between the assembly position and the workpiece unloading position to transfer the workpiece group from the assembly position to the positioning mold at the workpiece unloading position. Laser displacement sensors offer high detection accuracy and can detect objects without contact. By placing the laser displacement sensor at the top of the gasket testing machine and directing it towards the positioning mold, it is ensured that the laser displacement sensor can fully detect the range of the positioning mold, resulting in higher accuracy and improved detection precision.

[0010] Specifically, the assembly platform includes a high assembly platform and a low assembly platform. The high assembly platform is higher than the low assembly platform. The first placement position is located on the high assembly platform, the magazine is vertically disposed on the low assembly platform, and the second placement position is located at the bottom of the magazine. The assembly motion assembly includes a slide table and a lifting platform. The slide table is movably disposed on the low assembly platform and can move to the second placement position to receive the second workpiece. The lifting platform is vertically disposed on the low assembly platform and receives the second workpiece on the slide table to deliver it to the high assembly platform. This structure and principle are simple, reducing operational complexity and making operation easier. It can transfer the second workpiece placed on the low assembly platform to the high assembly platform, placing the second workpiece in the assembly position to ensure that it can be assembled into a workpiece group.

[0011] Furthermore, the magazine includes: a magazine box, a base, a baffle, and a second cylinder. A trajectory is formed inside the magazine box, and the trajectory is vertically arranged, allowing multiple second workpieces to be vertically stacked within the trajectory. The base is connected to the bottom of the magazine box, and the base has a discharge port with a shape consistent with the second workpiece, located at the bottom of the trajectory. The baffle is slidably disposed on the base, intermittently blocking the discharge port, and the second workpiece is discharged when the baffle leaves the discharge port. The second cylinder is connected to the baffle to drive the baffle to move. This structure is simple and easy to operate. The base and the second cylinder can be used to dispense the second workpieces. The second cylinder pushes the baffle away from the dispensing port to open the dispensing port, thus dispensing the second workpiece. When dispensing is no longer needed, the second cylinder returns to its original position, causing the baffle to block the dispensing port again, thus stopping the dispensing.

[0012] In some embodiments, the assembly platform further includes a support frame disposed on the assembly low platform, the magazine is mounted on the top of the support frame, and the assembly motion assembly further includes: a second guide rail and a second slider, the second guide rail being disposed on the assembly low platform and located within the support frame; the second slider cooperating with the second guide rail; in addition, the support frame is provided with a slide groove, the slide table is connected to the second slider via a sliding plate, the sliding plate being slidably engaged with the slide groove, and the slide table being able to slide along the slide groove to below the magazine, this arrangement can save space and ensure that the slide table slides along the slide groove to below the magazine to receive the second workpiece.

[0013] Specifically, the assembly motion assembly further includes a third cylinder connected between the second slider and the slide table. The third cylinder is used to drive the slide table to rise and fall, and when the slide table is below the magazine, the slide table rises to move closer to the discharge end of the magazine. This arrangement can improve the accuracy of the slide table receiving and ensure that the slide table can accurately receive the second workpiece.

[0014] Furthermore, the assembly motion assembly also includes multiple pusher cylinders, wherein some of the pusher cylinders are used to push the first workpiece from the first placement position to the assembly position, and other pusher cylinders are used to push the second workpiece from the lifting platform to the assembly position. The multiple pusher cylinders allow for adjustment of the positions of the first and second workpieces, enabling accurate transfer of both workpieces to the placement position and providing guidance and positioning for the first and second workpieces. This improves the convenience and accuracy of assembling the first and second workpieces.

[0044] The following is for reference. Figures 1-10A rivet system 100 according to an embodiment of the present invention is described.

[0045] like Figures 1-5 As shown, the riveting system 100 according to an embodiment of the present invention includes: a fixed table 10, a turntable 20, a gasket feeding machine 30, a gasket inspection machine 40, a workpiece assembly feeding machine 50, a riveting machine 60, and a discharge machine 70.

[0046] The fixed platform 10 has multiple workstations, including a gasket feeding station, a gasket inspection station, a workpiece feeding station, and a riveting station. A turntable 20 is rotatably mounted on the fixed platform 10. The multiple workstations are centrally symmetrically distributed around the rotation axis of the turntable 20. The turntable 20 has at least one positioning mold 21, which, when rotated, sequentially moves to the multiple workstations. A gasket feeding machine 30 is used to feed gaskets onto the positioning mold 21 located at the gasket feeding station. A gasket inspection machine... 40 is used to detect whether there is a gasket on the positioning mold 21 located at the gasket detection position; the workpiece assembly and feeding machine 50 is used to assemble at least two workpieces into a workpiece group and to feed the assembled workpiece group onto the positioning mold 21 located at the workpiece feeding position; the riveting machine 60 is set on the fixed table 10 and is used to rivet the workpiece group located on the positioning mold 21 at the riveting position to the gasket; the unloading machine 70 is used to remove the riveted workpiece group located at the riveting position from the positioning mold 21 and move it out of the turntable 20.

[0047] The turntable 20 is set on the fixed platform 10 and rotates 360 degrees on the fixed platform 10. Multiple workstations set on the fixed platform 10 are arranged in a ring and are symmetrically distributed around the rotation axis of the turntable 20. The multiple workstations are spaced apart from each other, and the angle between each workstation is the same.

[0048] Specifically, the outer periphery of the turntable 20 is provided with a gasket feeding machine 30, a gasket inspection machine 40, a workpiece assembly feeding machine 50, a riveting machine 60, and a discharge machine 70. The gasket feeding machine 30, the gasket inspection machine 40, the workpiece assembly feeding machine 50, the riveting machine 60, and the discharge machine 70 are all set on the fixed table 10. The gasket feeding machine 30, the gasket inspection machine 40, the workpiece assembly feeding machine 50, the riveting machine 60, and the discharge machine 70 are respectively set at the gasket feeding position, the gasket inspection position, the workpiece feeding position, and the riveting position on the fixed table 10. The fixed table 10 has two workpiece feeding positions symmetrical about the rotation axis of the turntable 20. The two workpiece assembly feeding machines 50 are respectively set at the two workpiece feeding positions. A reserved station is also set between the two workpiece feeding positions. The discharge machine 70 is located between the gasket feeding machine 30 and the riveting machine 60. The gasket feeding machine 30 and the riveting machine 60 are respectively set on both sides of the discharge machine 70. The outer periphery of the turntable 20 consists of the gasket feeding machine 30, the gasket inspection machine 40, the workpiece assembly feeding machine 50, the workpiece assembly feeding machine 50, the riveting machine 60 and the discharge machine 70.

[0049] It should be noted that at least one positioning mold 21 is provided on the turntable 20. When the turntable 20 rotates, it drives the positioning mold 21 to the workstation. When the turntable 20 drives the positioning mold 21 to the gasket feeding position, the gasket feeding machine 30 places the gasket on the positioning mold 21 corresponding to the gasket feeding position. As the turntable 20 continues to rotate, the positioning mold 21 corresponding to the gasket feeding position rotates to the gasket detection position. The gasket detection machine 40 can detect whether there is a gasket on the positioning mold 21 corresponding to the gasket detection position. As the turntable 20 continues to rotate, the positioning mold 21 corresponding to the gasket detection position rotates... Upon reaching the workpiece feeding position, the workpiece assembly feeding machine 50 assembles the workpiece and places the assembled workpiece onto the positioning mold 21 corresponding to the workpiece feeding position. The turntable 20 continues to rotate, and the positioning mold 21 corresponding to the workpiece feeding position rotates to the riveting position. The riveting machine 60 rivets the workpiece and the shim together on the positioning mold 21 corresponding to the riveting position. The turntable 20 continues to rotate, and the positioning mold 21 corresponding to the riveting position rotates to the discharge machine 70. The discharge machine 70 removes the riveted workpiece and shim from the positioning mold 21 below and moves the riveted workpiece and shim out of the turntable 20.

[0050] In addition, in the riveting system 100, the operation of the gasket feeding machine 30, the gasket inspection machine 40, the workpiece assembly feeding machine 50, the riveting machine 60, and the discharge machine 70 are all automatic. When the turntable 20 has two or more positioning molds 21, the gasket feeding machine 30, the gasket inspection machine 40, the workpiece assembly feeding machine 50, the riveting machine 60, and the discharge machine 70 work throughout the rotation of the turntable 20. The gasket feeding machine 30, the gasket inspection machine 40, the workpiece assembly feeding machine 50, the riveting machine 60, and the discharge machine 70 perform the same operation on each positioning mold 21 on the turntable 20, and perform the same operation on the positioning mold 21 that has rotated to that position as on the previous positioning mold 21.

[0051] For example, taking a turntable 20 with two positioning molds 21 as an example, when one positioning mold 21 on the turntable 20 rotates to the gasket feeding position, the gasket feeding machine 30 automatically picks up the gasket and places it on this positioning mold 21. When this positioning mold 21 rotates to the gasket detection position, the next positioning mold 21 rotates to the gasket feeding position, and the gasket detection machine 40 automatically detects this positioning mold 21 to confirm whether the gasket has been successfully placed on it. The gasket feeding machine 30 continues to pick up gaskets and place them on the next positioning mold 21. When this positioning mold 21 rotates to the workpiece feeding position, the next positioning mold 21 rotates to the gasket detection position. The workpiece assembly feeding machine 50 automatically assembles the workpiece and places it on this positioning mold 21. At the same time, the gasket detection machine 40 automatically detects whether a gasket is placed on the next positioning mold 21. When this positioning mold 21 rotates to the riveting position, the next positioning mold 21 rotates... When the workpiece is moved to the workpiece placement position, the riveting machine 60 rivets the workpiece and the shim on the positioning mold 21. At the same time, the workpiece assembly and unloading machine 50 automatically assembles the workpiece and places the assembled workpiece onto the next positioning mold 21 after this positioning mold 21. When this positioning mold 21 rotates to the unloading machine 70, the next positioning mold 21 rotates to the riveting position. The unloading machine 70 removes the riveted workpiece and shim from the positioning mold 21 and moves it out of the turntable 20. The assembly machine 60 rivets the workpiece and the shim on the next positioning mold 21 of this positioning mold 21; after the turntable 20 completes one revolution, this positioning mold 21 rotates back to the shim feeding position, and the next positioning mold 21 of this positioning mold 21 rotates to the discharge machine 70. The shim feeding machine 30 automatically picks up the shim and places it on this positioning mold 21. At the same time, the discharge machine 70 causes the riveted workpiece and shim on the next positioning mold 21 of this positioning mold 21 to separate from the positioning mold 21 and move it out of the turntable 20.

[0052] According to an embodiment of the present invention, the riveting system 100, by sequentially arranging a gasket feeding machine 30, a gasket detection machine 40, a workpiece assembly feeding machine 50, a riveting machine 60, and a discharge machine 70 on the outer periphery of the turntable 20, can operate according to the process of the riveting system 100. By setting the operation mode of the gasket feeding machine 30, the gasket detection machine 40, the workpiece assembly feeding machine 50, the riveting machine 60, and the discharge machine 70 to automatic operation, it can automatically place gaskets and detect the presence or absence of gaskets, and can also automatically assemble workpieces and rivet the assembled workpieces with the gaskets. The entire process does not require manual operation, saving manpower, avoiding the problem of work-related injuries caused by manual operation, improving safety, and the efficiency of automatic operation is higher than that of manual operation. Moreover, the accuracy and stability of automatic operation are higher, thus improving product quality.

[0053] like Figure 2 and Figure 10As shown, in some embodiments, the gasket feeding machine 30 includes: a first base frame 31, a gasket vibrating plate, and a movable material picking member 32. The first base frame 31 is mounted on the fixed platform 10. The discharge end of the gasket vibrating plate is located adjacent to the first base frame 31. The movable material picking member 32 is movably mounted on the first base frame 31. The movable material picking member 32 is provided with a suction nozzle. The movable material picking member 32 can drive the suction nozzle to move to the discharge end of the gasket vibrating plate to pick up the gasket. The movable material picking member 32 can also drive the suction nozzle to move above the positioning mold 21 to release the gasket.

[0054] Specifically, the first base frame 31 is set on the outer periphery of the turntable 20, and its bottom end is fixed on the fixed platform 10. The height of the first base frame 31 is higher than the height of the turntable 20. The movable material picking component 32 is set on the upper end of the first base frame 31 and can move on the upper end of the first base frame 31. The movable material picking component 32 can move towards the turntable 20 or away from the turntable 20. The movable material picking component 32 is equipped with a suction nozzle. The movement of the movable material picking component 32 on the first base frame 31 can drive the suction nozzle to move synchronously. The pad vibrating plate is set on the outer periphery of the turntable 20, and the discharge end of the pad vibrating plate is set near the first base frame 31.

[0055] It should be noted that the gasket is vibrated out from the discharge end of the gasket vibratory feeder. The gasket is located at the discharge port of the gasket vibratory feeder. The moving material picker 32 moves away from the turntable 20, driving the suction nozzle to move above the discharge end of the gasket vibratory feeder. The suction nozzle picks up the gasket located at the discharge port of the gasket vibratory feeder. The moving material picker 32 then moves towards the turntable 20 until the suction nozzle moves above the positioning mold 21. At this time, the suction nozzle releases the gasket and places it on the positioning mold 21. In this way, the gasket vibrated out of the gasket vibratory feeder can be automatically picked up and moved above the positioning mold 21 and placed on the positioning mold 21, realizing the automatic gasket picking and placing function of the gasket feeding machine 30 without manual operation, saving manpower.

[0056] like Figure 2 and Figure 10 As shown, specifically, the gasket feeding machine 30 also includes: a first guide rail 33 provided on the first base frame 31, a first slider 34 cooperating on the first guide rail 33, a first cylinder connected to the first slider 34, and a moving material picking component 32 connected to the first slider 34.

[0057] Specifically, the first base frame 31 is vertically mounted on the fixed platform 10, and the first guide rail 33 is horizontally mounted on the upper end of the first base frame 31. The first guide rail 33 is perpendicular to the first base frame 31, and one end of the first guide rail 33 faces the turntable 20. The end of the first guide rail 33 near the turntable 20 is located above the turntable 20. The first slider 34 cooperates with the first guide rail 33 and moves along the first guide rail 33. The first slider 34 can move towards or away from the turntable 20. One side of the first slider 34 is fitted inside the first guide rail 33, and the other side of the first slider 34 is connected to a first cylinder. The moving material picker 32 is connected to the first cylinder. The first cylinder is connected between the first slider 34 and the moving material picker 32. The first cylinder can drive the moving material picker 32 to move vertically.

[0058] It should be noted that when the first slider 34 moves away from the turntable 20, it drives the moving material picker 32 to move away from the turntable 20. When the moving material picker 32 moves above the discharge end of the pad vibrating plate, the first slider 34 stops moving. The first cylinder drives the moving material picker 32 to move towards the pad vibrating plate, and the moving material picker 32 picks up the pad. When the first slider 34 moves towards the turntable 20, it drives the moving material picker 32 to move towards the turntable 20. When the moving material picker 32 moves above the positioning mold 21, the first slider 34 stops moving. The first cylinder drives the moving material picker 32 to move towards the positioning mold 21, and the moving material picker 32 releases the pad and places the pad on the positioning mold 21. A first guide rail 33 and a first slider 34 are provided, and a first cylinder is provided. The first cylinder is connected between the first slider 34 and the moving material picker 32, which can adjust the position of the moving material picker 32 and ensure the accuracy of the moving direction of the moving material picker 32, thereby ensuring that the moving material picker 32 can smoothly pick up and put in the pad.

[0059] like Figure 2 and Figure 5 As shown, the gasket inspection machine 40 is further mounted on the fixed stage 10, and the gasket inspection machine 40 includes a laser displacement sensor for irradiating the positioning mold 21.

[0060] It should be noted that the gasket inspection machine 40 is located on the outer periphery of the turntable 20, with its bottom fixed to the fixed platform 10. The height of the gasket inspection machine 40 is higher than that of the turntable 20, and its upper end is located above the positioning mold 21. A laser displacement sensor is installed at the upper end of the gasket inspection machine 40, facing the positioning mold 21. The laser displacement sensor can detect whether a gasket is placed on the positioning mold 21. Various types of laser displacement sensors are available, including laser distance sensors and infrared sensors, etc. No specific limitation is made here; the appropriate sensor can be selected based on actual needs. The laser displacement sensor has high detection accuracy and can detect without contact with the object being measured. Positioning the laser displacement sensor at the upper end of the gasket inspection machine 40 and facing the positioning mold 21 ensures that the laser displacement sensor can fully detect the area of ​​the positioning mold 21, resulting in higher data accuracy and improved detection precision.

[0061] like Figure 3 As shown, in some embodiments, at least two workpieces include a first workpiece and a second workpiece. The workpiece assembly and unloading machine 50 includes: an assembly table 51, a workpiece vibratory feeder 52, a magazine 53, an assembly motion assembly 54, and a transfer robot 55. The assembly table 51 is provided with a first placement position, a second placement position, and an assembly position. The discharge end of the workpiece vibratory feeder 52 is connected to the first placement position to place the first workpiece into the first placement position. The magazine 53 is provided on the assembly table 51, and the discharge end of the magazine 53 is set towards the second placement position to place the second workpiece into the second placement position. The assembly motion assembly 54 is provided on the assembly table 51 and is used to transfer the first workpiece from the first placement position and the second workpiece from the second placement position to the assembly position, so that the first workpiece and the second workpiece form a workpiece group at the assembly position. The transfer robot 55 is provided on the fixed table 10, and the execution end of the transfer robot 55 is movable between the assembly position and the workpiece unloading position to transfer the workpiece group from the assembly position to the positioning mold 21 at the workpiece unloading position.

[0062] Specifically, the workpiece vibratory feeder 52 is positioned on one side of the assembly table 51, which is stepped. The workpiece vibratory feeder 52 is positioned near the higher side of the assembly table 51. The first workpiece is vibrated out from the discharge end of the workpiece vibratory feeder 52, which is connected to the first placement position. The first workpiece is placed at the first placement position. The magazine 53 is positioned above the second placement position, and the second workpiece is located inside the magazine 53. The discharge end of the magazine 53 is located at the bottom of the magazine 53. The second workpiece moves downward within the magazine 53, with the discharge end of the magazine 53 facing the second placement position. The second workpiece is placed from the magazine 53 to the second placement position. The workpiece vibratory feeder 52 places the first workpiece at the first placement position, the assembly motion assembly 54 moves the first workpiece to the assembly position, the magazine 53 places the second workpiece at the second placement position, the assembly motion assembly 54 moves the second workpiece to the assembly position, and the assembly motion assembly 54 assembles the first and second workpieces at the assembly position, forming a workpiece assembly.

[0063] It should be noted that the transfer robot 55 is mounted on the fixed platform 10, with the frame of the transfer robot 55 vertically fixed to the platform 10. The arm of the transfer robot 55 is perpendicular to the frame, with one end of the arm facing the positioning mold 21. The actuator of the transfer robot 55 is connected to the arm, allowing it to move along the arm and towards both the assembly position and the positioning mold 21. The actuator moves towards the assembly position to remove the workpiece assembly, and then moves towards the positioning mold 21 to place the workpiece assembly onto it. This configuration ensures that the movement trajectories of the first and second workpieces do not interfere with each other. The first and second workpieces are transferred to the assembly position, assembled into a workpiece assembly, and then the actuator of the transfer robot 55 places the workpiece assembly onto the positioning mold 21, reducing operational difficulty and improving efficiency.

[0064] like Figure 3 As shown, specifically, the assembly platform 51 includes an assembly high platform 511 and an assembly low platform 512. The assembly high platform 511 is higher than the assembly low platform 512. The first placement position is located on the assembly high platform 511, the magazine 53 is vertically arranged on the assembly low platform 512, and the second placement position is located at the bottom of the magazine 53. The assembly motion assembly 54 includes a slide 541 and a lifting platform 542. The slide 541 is movably arranged on the assembly low platform 512 and can be moved to the second placement position to receive the second workpiece. The lifting platform 542 is vertically arranged on the assembly low platform 512 and receives the second workpiece on the slide 541 to be sent to the assembly high platform 511.

[0065] It should be noted that the higher layer of the assembly platform 51 is the assembly high platform 511, and the lower layer is the assembly low platform 512. The discharge end of the workpiece vibratory feeder 52 is connected to the assembly high platform 511, which is connected to the first placement position located on the assembly high platform 511. The magazine 53 is disposed on the assembly low platform 512, and the position on the assembly low platform 512 corresponding to the magazine 53 is the second placement position. The second workpiece in the magazine 53 moves toward the second placement position. The assembly motion assembly 54 is disposed on the assembly platform 51, and the slide 541 of the assembly motion assembly 54 is disposed on the assembly low platform 512. It is movably disposed at the bottom of the magazine 53. When the second workpiece moves from top to bottom in the magazine 53, the slide 541 moves to the second placement position to receive the second workpiece fed by the discharge end of the magazine 53.

[0066] The lifting platform 542 is also mounted on the lower assembly platform 512. The lifting platform 542 is vertically oriented and extends upwards, its height being flush with the assembly position. The lifting platform 542 receives the second workpiece from the slide table 541. A photoelectric sensor is also installed on the lifting platform 542. When the photoelectric sensor detects the second workpiece, the portion of the lifting platform 542 receiving the second workpiece rises to its top, thus transferring the second workpiece to the higher assembly platform 511. This structure and principle are simple, reducing operational complexity and making operation easier. It allows the second workpiece, placed on the slide table 541 on the lower assembly platform 512, to be transferred to the higher assembly platform 511, ensuring the second workpiece is positioned in the assembly position and can be assembled into a workpiece group.

[0067] like Figure 6 and Figure 9 As shown, the magazine 53 further includes: a magazine box 531, a base 532, a baffle 533, and a second cylinder. A ballistic trajectory is formed inside the magazine box 531, and the ballistic trajectory is vertically arranged. Multiple second workpieces can be vertically stacked in the ballistic trajectory. The base 532 is connected to the bottom of the magazine box 531, and the base 532 is provided with a discharge port that is consistent with the shape of the second workpiece. The discharge port is located at the bottom of the ballistic trajectory. The baffle 533 is slidably arranged on the base 532. The baffle 533 intermittently blocks the discharge port, and the second workpiece is discharged when the baffle 533 leaves the discharge port. The second cylinder is connected to the baffle 533 to drive the baffle 533 to move.

[0068] Specifically, the cartridge box 531 cooperates with the base 532. The cartridge box 531 is located above the base 532. The trajectory inside the cartridge box 531 is made to follow the shape of the second workpiece. After the second workpiece is placed into the trajectory, the trajectory automatically guides the second workpiece to be aligned, so that multiple second workpieces are stacked vertically. Multiple second workpieces can slide from top to bottom along the trajectory to the discharge port of the base 532. A baffle 533 is provided on the base 532, and a second cylinder is provided outside the base 532. For example, the baffle 533 is connected to the second cylinder. The baffle 533 is located at the discharge port and can slide on the base 532 with the direction of setting the baffle 533 forward and the direction of setting the second cylinder backward. When the second cylinder moves forward, it drives the baffle 533 to move forward, and the baffle 533 moves away from the discharge port. At this time, the discharge port opens, and the second workpiece that has slid down the trajectory to the discharge port is discharged from the discharge port. When the second cylinder retracts, it drives the baffle 533 back to the initial position and back to the discharge port. The discharge port is blocked, and the second workpiece that has slid down the trajectory to the discharge port cannot fall from the discharge port.

[0069] In another embodiment, a spring can also be installed on the base 532, connected to a baffle 533. The baffle 533 blocks the front of the second cylinder. When the second cylinder moves forward, it drives the baffle 533 to move forward, moving the baffle 533 away from the discharge port. At this time, the discharge port opens, and the second workpiece that has slid down the trajectory to the discharge port is discharged from the discharge port. When the second cylinder retracts, it separates from the baffle 533. The baffle 533 returns to its initial position under the action of the spring, returning to the discharge port again. The discharge port is blocked, and the second workpiece that has slid down the trajectory to the discharge port cannot fall from the discharge port. This structure is simple and easy to operate. The second workpiece can be dispensed by the base 532 and the second cylinder. The second cylinder pushes the baffle 533 away from the dispensing port to open the dispensing port, thereby dispensing the second workpiece. When dispensing is not needed, the second cylinder returns to its original position, causing the baffle 533 to block the dispensing port again, thus stopping the dispensing.

[0070] like Figures 6-8 As shown, in some embodiments, the assembly platform 51 further includes a support frame 5121 disposed on the assembly low platform 512, and the magazine 53 is mounted on the top of the support frame 5121. The assembly motion assembly 54 further includes: a second guide rail 543 and a second slider 544. The second guide rail 543 is disposed on the assembly low platform 512 and located inside the support frame 5121; the second slider 544 is fitted on the second guide rail 543; in addition, the support frame 5121 is provided with a slide groove 51211, and the slide 541 is connected to the second slider 544 through the slide plate 5411. The slide plate 5411 is slidably fitted at the slide groove 51211, and the slide 541 can slide along the slide groove 51211 to below the magazine 53.

[0071] Specifically, a support frame 5121 is mounted on an assembly platform 512, with its top positioned at a distance from the top surface of the platform. A magazine 53 is mounted above the support frame 5121, with its bottom contacting the top of the support frame 5121. A second guide rail 543 is mounted on the assembly platform 512 and located below the centerline of the support frame 5121 along its length. The length of the second guide rail 543 is at least the same as the length of the support frame 5121. A groove 51211 is provided at the center line of the degree direction. The slide plate 5411 is fitted in the groove 51211 and can slide along the groove 51211. The second slider 544 is fitted above the second guide rail 543. The slide plate 5411 is located above the second slider 544. The second slider 544, the slide table 541 and the slide plate 5411 are connected and slide synchronously. This arrangement can save space and ensure that the slide table 541 slides along the groove 51211 to the bottom of the magazine 53 to receive the second workpiece.

[0072] Specifically, the assembly motion assembly 54 also includes a third cylinder connected between the second slider 544 and the slide table 541. The third cylinder is used to drive the slide table 541 to rise and fall, and when the slide table 541 is below the magazine 53, the slide table 541 rises to move closer to the discharge end of the magazine 53. The third cylinder is located on the side of the slide table 541 and is connected to the slide table 541. The third cylinder can drive the slide table 541 to move up or down. When it drives the slide table 541 to rise, the slide table 541 is in a rising state. When it drives the slide table 541 to fall to the initial position, the slide table 541 is in a reset state. When the magazine 53 puts in the second workpiece, the slide table 541 rises, and its position is closer to the discharge end of the magazine 53. This setting can improve the accuracy of the slide table 541 in receiving the workpiece and ensure that the slide table 541 can accurately receive the second workpiece.

[0073] like Figure 1 and Figure 5 As shown, the assembly motion assembly 54 further includes a plurality of pusher cylinders, wherein some of the pusher cylinders are used to push the first workpiece at the first placement position to the assembly position, and other pusher cylinders are used to push the second workpiece on the lifting platform 542 to the assembly position.

[0074] Specifically, the assembly motion assembly 54 consists of multiple pusher cylinders, including a pusher cylinder for pushing the workpiece and a pusher cylinder for guiding the workpiece. The workpiece vibrating plate 52 places the first workpiece into the first placement position. The first workpiece is pushed to the placement position by two pusher cylinders arranged perpendicularly in two directions. The first workpiece is pushed by a pusher cylinder whose direction is parallel to that of the transfer robot 55. This pusher cylinder is located near the turntable 20 and pushes the first workpiece away from the turntable 20 until it pushes the first workpiece close to another pusher cylinder. The other pusher cylinder is perpendicular to the direction of the transfer robot 55 and pushes the first workpiece toward the placement position until it is pushed to the placement position. After the first workpiece moves to the placement position, the pusher cylinder for guiding the workpiece guides the position of the first workpiece.

[0075] Furthermore, the second workpiece is raised and transferred to the same height as the first workpiece via the lifting platform 542. It is then pushed towards the placement position by a pusher cylinder until it is in place. Similarly, it is guided by a guide cylinder to assemble with the first workpiece into a workpiece assembly. The multiple pusher cylinders allow for adjustment of the positions of the first and second workpieces, ensuring accurate transfer to the placement position and enabling guidance and positioning of both. This improves the convenience and accuracy of assembling the first and second workpieces.
