Description

Technical Field

[0001] This invention relates to the field of stamping machine assembly technology, and more specifically, to an assembly station and a final assembly line. Background Technology

[0002] The existing stamping press assembly process suffers from multiple technical bottlenecks: The limited assembly space and small internal working area of ​​the stamping machine make it difficult for operators to hold tools and perform tasks, resulting in high assembly difficulty. The assembly requires high precision. Key components, such as the coaxiality of the reducer and the machine body, and the clearance between the bearing and the reducer output shaft, are difficult to consistently meet the standards with manual assembly. The assembly process is tedious and complex, involving multiple steps such as speed reducer positioning, bolt pre-tightening, bearing heating and installation, and gland sealing. Each step requires multiple adjustments and verifications, and manual operation takes a long time.

[0003] Operating tools in confined spaces may cause safety accidents such as pinching and cutting; fatigued workers may cause assembly deviations, affecting product consistency; operational errors may lead to bolt tightening torque exceeding tolerance, causing equipment vibration or premature failure.

[0004] The aforementioned problems result in low automation in stamping press assembly and limited production efficiency. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] to this end: The first aspect of the present invention provides an assembly station; A second aspect of the invention provides an assembly line.

[0007] In view of this, in a first aspect, the present invention provides an assembly station for assembling a stamping machine, the stamping machine including a machine body, a reducer, bearings and a pressure cap, and the assembly station including a frame, a lifting assembly, a first gantry, a first assembly assembly and a second assembly assembly.

[0008] The first gantry frame is installed on the frame. The first gantry frame includes a first lifting arm and a second lifting arm, which can slide relative to the frame. The first assembly assembly is installed on the first lifting arm. The second assembly assembly is installed on the second lifting arm. When assembling the stamping machine, the lifting assembly is used to drive the reducer to move relative to the machine body, the first assembly assembly is used to drive the bearing to move relative to the machine body, and the second assembly assembly is used to drive the pressure cap to move relative to the machine body.

[0009] The assembly station proposed in this invention achieves precise positioning of the reducer and bolt tightening operation through the coordination of the lifting component and the first gantry frame, replacing manual operation in confined spaces and reducing the risk of pinching and cutting. The first assembly component integrates heating and propulsion functions. It heats the inner ring of the bearing before pushing it between the output shaft of the reducer and the mounting port of the machine body, solving the problems of coaxiality and fit clearance and improving assembly accuracy. The second assembly component uses a magnet to attract the cover and, together with tightening parts and other structures, achieves cover snapping and bolt locking, simplifying the multi-process verification process; The entire process adopts a high degree of automation to replace manual operation, reducing assembly deviations caused by fatigue, ensuring product consistency, improving assembly efficiency, solving the problem of limited production efficiency, and achieving safe, accurate and efficient stamping machine assembly operations.

[0036] The first hoist 210 includes a slide table 212 and a carriage 211, which are slidable relative to the frame 1; a second gantry 220 is mounted on the slide table 212; a quick-change clamp 230 is mounted on the second gantry 220, which is movable relative to the first hoist 210; a first cross slide table 240 is mounted on the carriage 211; a gripper assembly 250 is mounted on the first cross slide table 240; a gripper 260 is stored in the gripper assembly 250; and a first bolt storage rack 270 is mounted on the reducer.

[0037] In this embodiment, the lifting assembly 200 includes a first hoist 210, a second gantry frame 220, a quick-change clamp 230, a first cross slide 240, a gripper frame 250, a gripper 260, and a first bolt storage rack 270.

[0038] The first hoist 210 includes a slide table 212 and a carriage 211. The first hoist 210 is fixedly installed at the work station. The slide table 212 and the carriage 211 can slide relative to the frame 1 along a first direction and a third direction.

[0039] The second gantry 220 is installed on the slide table 212, so that the second gantry 220 can move with the slide table 212.

[0040] The quick-change clamp 230 is installed on the second gantry 220 and can move relative to the first hoist 210.

[0041] The first cross slide 240 is mounted on the slide 211, so that the first cross slide 240 can move with the slide 211. The first cross slide 240 is used to support the geared motor.

[0042] The gripper frame 250 is installed on the first cross slide 240, and the gripper 260 is stored in the gripper frame 250. There are two types of grippers 260, one for long bolts and the other for short bolts, so that the quick-change clamp 230 can be used interchangeably.

[0043] The first bolt storage rack 270 is installed on the reducer to store long bolts and short bolts. The quick-change fixture 230 with the corresponding gripper 260 installed can pick up long bolts or short bolts for the assembly operation of the reducer.

[0044] The first hoist 210 lifts the reducer and aligns it with the mounting port of the machine body. Through the cooperation of the quick-change clamp 230, gripper 260, gripper frame 250 and the first bolt storage rack 270, long bolts can be taken first, at least two long bolts can be passed through the through holes of the reducer and screwed onto the machine body, the reducer can be moved closer to the machine body and initially positioned, short bolts can be taken and connected into the through holes where there are no long bolts at this time, then the long bolts can be removed and put back into the first bolt storage rack 270, and finally the remaining short bolts can be screwed into the through holes where the long bolts have been removed, so as to complete the assembly of the reducer onto the machine body.

[0045] Optionally, please refer to Figure 8 The quick-change fixture 230 includes an upper mating plate, a lower mating plate, and an electrical connector.

[0046] The upper docking plate is installed on the second gantry 220 and has an upper contact. The lower docking plate is installed on the gripper 260 and has a lower contact. The electrical connector is installed on the upper docking plate.

[0047] When the upper and lower mating plates are plugged into each other, the electrical connector is used to connect and lock the upper and lower mating plates, while the upper and lower contacts abut against each other to provide power to the gripper 260.

[0048] Optionally, the electrical connector includes a fourth servo motor and a locking pin. The output shaft of the fourth servo motor is equipped with a locking pin, and a locking groove is provided on the lower connecting plate. The locking pin engages with the locking groove. When the fourth servo motor is working, it can swing the locking pin, thereby completing the engagement or disengagement with the locking groove.

[0049] Optionally, please refer to Figure 9 The gripper 260 includes a support 261, a third servo motor 262, a gear transmission box 263, and a bolt sleeve 264.

[0050] Support 261 is mounted on the lower docking plate, third servo motor 262 is mounted on support 261, gear transmission box 263 is mounted on the lower docking plate, one end of gear transmission box 263 is connected to the output shaft of third servo motor 262, and the other end of gear transmission box 263 is connected to bolt sleeve 264.

[0051] When the third servo motor 262 is working, it can be driven by the gear transmission box 263 to rotate the bolt sleeve 264, thereby rotating the bolt inserted in the bolt sleeve 264 to complete the bolt installation operation. The gear transmission box 263 is set so that the output shaft of the bolt sleeve 264 and the third servo motor 262 are offset, that is, not on the same axis, which is beneficial to insert the bolt into the narrow space near the reducer for installation.

[0052] Optionally, the gripper frame 250 is stepped, which facilitates multi-level storage at different heights to make it easy to pick up and replace the quick-change clamp 230.

[0053] Please see Figure 5 and Figure 6 Optionally, the first hoist 210 includes a third slide rail 213, a fourth slide rail 214, a reduction motor 215, a fourth gear, a fourth rack 216, a fourth motor 218, a transmission shaft 217, an eleventh motor 219, a tenth rack 290, an eleventh gear, a tenth gear, a slide table 212, and a carriage 211.

[0054] The third slide rail 213 is installed at the workstation and is set along the first direction. The fourth slide rail 214 is slidably assembled on the third slide rail 213 and is set along the third direction.

[0055] The geared motor 215 is mounted on the fourth slide rail 214, and the drive shaft 217 is rotatably mounted on the fourth slide rail 214. One end of the drive shaft 217 is connected to the output shaft of the geared motor 215. The fourth gear is connected to the end of the drive shaft 217 away from the geared motor 215. The fourth rack 216 is mounted on the third slide rail 213, and the fourth gear meshes with the fourth rack 216. After being driven by the drive shaft 217, the geared motor 215 rotates the fourth gear. Through the meshing relationship between the fourth gear and the fourth rack 216, the fourth slide rail 214 can reciprocate along the fourth rack 216.

[0056] The tenth rack 290 is mounted on the fourth slide rail 214, the fourth motor 218 is mounted on the slide 211, and the tenth gear is mounted on the output shaft of the fourth motor 218, and the tenth gear meshes with the tenth rack 290; when the fourth motor 218 is working, it can rotate the tenth gear, and through the meshing relationship between the tenth gear and the tenth rack 290, it can move the slide 211 along a third direction.

[0057] The eleventh motor 219 is mounted on the slide table 212, and the eleventh gear is mounted on the output shaft of the eleventh motor 219. The eleventh gear also meshes with the tenth rack 290. When the eleventh motor 219 is working, it can rotate the eleventh gear. Through the meshing relationship between the eleventh gear and the tenth rack 290, it can move the slide table 212 along a third direction.

[0058] This allows the slide table 212 and the carriage 211 to move along the first direction and the third direction, providing a mobile foundation for the first cross slide table 240 to lift the reducer and the second gantry 220 to move the quick-change fixture 230.

[0059] Please see Figure 7 Optionally, the second gantry 220 includes a fifth slide rail 221, a sixth slide rail 222, a fifth motor 223, a sixth motor 224, a seventh motor 225, a fifth gear, a sixth gear, a fifth rack 226, a sixth rack 227, a second screw 228, a second base 229, and a third lifting arm.

[0060] The fifth slide rail 221 is installed on the slide table 212 and mainly serves as a support. The sixth slide rail 222 is slidably assembled on the fifth slide rail 221 and can slide along the first direction on the fifth slide rail 221. There are two second bases 229, which are slidably installed on the sixth slide rail 222 and can slide along the second direction on the sixth slide rail 222. The third lifting arm is slidably assembled on the second base 229 and can slide along the third direction on the second base 229.

[0061] The fifth motor 223 is mounted on the sixth slide rail 222, the fifth gear is mounted on the output shaft of the fifth motor 223, and the fifth rack 226 is mounted on the fifth slide rail 221, with the fifth gear meshing with the fifth rack 226. After the fifth motor 223 rotates the fifth gear, the meshing relationship provides the sixth slide rail 222 with the power to move along the fifth rack 226.

[0062] The sixth motor 224 is mounted on the second base 229, the sixth gear is mounted on the output shaft of the sixth motor 224, and the sixth rack 227 is fixedly mounted on the sixth slide rail 222, and the sixth gear meshes with the sixth rack 227; after the sixth motor 224 rotates the sixth gear, the meshing relationship can provide the second base 229 with the power to move along the sixth rack 227.

[0063] The third lifting arm is slidably mounted on the second base 229, the seventh motor 225 is mounted on the third lifting arm, and the second screw 228 is rotatably mounted on the third lifting arm. One end of the second screw 228 is connected to the output shaft of the seventh motor 225, and the second base 229 is screwed together with the second screw 228. After the seventh motor 225 rotates the second screw 228, it can provide the third lifting arm with the power to lift along the third direction through the screwed relationship between the second screw 228 and the second base 229.

[0064] This allows the quick-change clamp 230 on the third lifting arm to move individually or simultaneously in three directions, meeting the movement requirements for bolt installation.

[0065] In addition, the first cross slide 240 includes two linear slides, which are arranged perpendicularly to each other. Each linear slide includes a guide rail, a lead screw, a second servo motor, and a lead screw slider. The lead screw slider is used to support the reducer and can adjust the displacement along the first direction and the second direction to improve the installation accuracy of the reducer.

[0066] Furthermore, a tray is also fixedly installed on the lead screw slider. The tray is used to increase the contact area with the reducer and improve the stability of lifting the reducer. A positioning pin can also be installed on the upper side of the tray, and the bottom of the reducer is provided with a pin hole that matches the positioning pin, thereby improving the positional accuracy of the reducer placed on the tray.

[0067] Please see Figure 4 In some embodiments of the present invention, optionally, the number of the first hoist 210, quick-change clamp 230, first cross slide 240, gripper frame 250 and first bolt storage rack 270 are the same, and there are one to three.

[0068] For example, when one of each is used, the number of the first hoist 210, quick-change clamp 230, first cross slide 240, gripper frame 250 and first bolt storage rack 270 are one each.

[0069] A first hoist 210 has a slide 212 and a carriage 211. A second gantry 220 on the slide 212 and a first cross slide 240 on the carriage 211 can move along a third direction. A gripper frame 250, in conjunction with a first bolt storage rack 270, can also complete the bolt connection installation operation.

[0070] For example, when two are used respectively, the number of the first hoist 210, quick-change clamp 230, first cross slide 240, gripper frame 250 and first bolt storage rack 270 are two each, and they are arranged symmetrically.

[0071] The two first hoists 210 have two oppositely arranged slides 212 and two oppositely arranged carriages 211. The second gantry 220 fixed between the two slides 212 moves more smoothly. Each of the two carriages 211 is equipped with a first cross slide 240, which lifts the reducer more smoothly. The two gripper frames 250 work in conjunction with the two first bolt storage racks 270 to improve the installation efficiency of bolt connections.

[0072] For example, when three are used respectively, the number of the first hoist 210, quick-change clamp 230, first cross slide 240, gripper frame 250 and first bolt storage rack 270 are three, two of which are symmetrically arranged, and the other is located on the side of the reducer away from the machine body.

[0073] The three first hoists 210 have three oppositely arranged slides 212 and three oppositely arranged carriages 211. The second gantry 220 fixed between the three slides 212 moves more smoothly. Each of the three carriages 211 is equipped with a first cross slide 240, which lifts the reducer more smoothly. The three gripper frames 250 work in conjunction with the three first bolt storage racks 270 to further improve the installation efficiency of bolt connections.

[0079] In this embodiment, the first assembly component 400 includes a first rotating platform 410, a propulsion module 420, and a heating component 430.

[0080] The first rotating platform 410 is installed on the first lifting arm 310, so that the first rotating platform 410 can move with the first lifting arm 310.

[0081] The propulsion module 420 is mounted on the first rotating platform 410, which is used to rotate the propulsion module 420, thereby enabling the propulsion module 420 to be horizontally rotated relative to the first lifting arm 310.

[0082] The heating component 430 is installed at the end of the propulsion module 420. The heating component 430 flips with the propulsion module 420. When the bearing is sleeved on the heating component 430, the heating component 430 is used to heat the bearing and increase the inner diameter through thermal expansion to facilitate installation.

[0083] When in use, the first assembly component 400 moves to the bearing and cover supply position along with the first lifting arm 310. After the bearing is fitted onto the push module 420, it is heated. Then, while rotating, it moves to the assembly position of the machine body mounting port. After alignment, the bearing is pushed between the output shaft of the reducer and the mounting port to complete the bearing assembly.

[0084] Please see Figure 11 Optionally, the first rotating platform 410 includes a support base 412, a first drive motor 411, a first drive gear 413, and a first driven gear 414.

[0086] After the first drive motor 411 rotates the first drive gear 413, it can drive the propulsion module 420 to perform a flipping action through the meshing transmission relationship of the first drive gear 413 and the first driven gear 414, which reduces speed and increases torque.

[0087] Please see Figure 10 Optionally, the heating assembly 430 includes a shell and an electric heating wire.

[0088] The cylindrical shell is installed at the end of the propulsion module 420. The outer diameter of the cylindrical shell is matched with the inner diameter of the bearing to support the bearing. The electric heating wire is installed inside the cylindrical shell and heats up when energized.

[0089] After the heating assembly 430 is fitted onto the bearing, the electric heating wire evenly heats the cylinder shell, thereby heating the inner ring of the bearing and increasing the inner diameter of the bearing.

[0090] Please see Figure 12 In some embodiments of the present invention, the propulsion module 420 may optionally include a housing 421, an eighth motor 422, a seventh gear 423, a guide rail 424, a slide table 425, an eighth rack 426, and a push rod 427.

[0091] The housing 421 is mounted on the first rotating platform 410; the eighth motor 422 is mounted on the first rotating platform 410, and the output shaft of the eighth motor 422 extends into the housing 421; the seventh gear 423 is mounted on the output shaft of the eighth motor 422; the guide rail 424 is mounted on the housing 421; the slide table 425 is slidably mounted on the guide rail 424; the eighth rack 426 is mounted on the slide table 425, and the eighth rack 426 meshes with the seventh gear 423; the push rod 427 is mounted on the slide table 425; a through hole 428 is opened on the side wall of the housing 421 near the heating component 430, and the push rod 427 is inserted into the through hole 428 for assembly.

[0092] In this embodiment, the propulsion module 420 includes a housing 421, an eighth motor 422, a seventh gear 423, a guide rail 424, a slide table 425, an eighth rack 426, and a push rod 427.

[0093] The housing 421 is mounted on the first rotating platform 410, and the housing 421 can rotate horizontally under the drive of the first rotating platform 410.

[0094] The eighth motor 422 is mounted on the first rotating platform 410. The output shaft of the eighth motor 422 extends into the housing 421. The eighth motor 422 rotates horizontally under the drive of the first rotating platform 410. The eighth motor 422 is relatively stationary with respect to the housing 421.

[0095] The seventh gear 423 is mounted on the output shaft of the eighth motor 422, and the seventh gear 423 can rotate in both forward and reverse directions under the drive of the eighth motor 422.

[0096] The guide rail 424 is mounted on the housing 421, and the slide table 425 is slidably mounted on the guide rail 424, and the slide table 425 can reciprocate along the guide rail 424.

[0097] The eighth rack 426 is mounted on the slide table 425 and is located on the upper side of the slide table 425. The eighth rack 426 meshes with the seventh gear 423. The eighth rack 426 can convert the forward and reverse rotation of the seventh gear 423 into linear reciprocating motion, thereby reciprocating to drive the slide table 425 on the guide rail 424.

[0098] The push rod 427 is installed on the slide table 425. The side wall of the housing 421 near the heating component 430 has a through hole 428. The push rod 427 is inserted into the through hole 428. The push rod 427 can move with the slide table 425 and extend out of the housing 421 or retract into the housing 421 along the through hole.

[0099] After the bearing on the heating assembly 430 is heated and moved to the assembly position, the eighth motor 422 rotates the seventh gear 423, and the meshing eighth rack 426 drives the slide table 425 to slide along the guide rail 424, thereby pushing out the push rod 427 in the through hole. The push rod 427 pushes the bearing between the output shaft of the reducer and the mounting port. After the bearing assembly operation is completed, it is reset for use.

[0100] Please see Figure 12 In some embodiments of the present invention, optionally, heating components 430 are installed at both ends of the propulsion module 420, through holes 428 are opened at both ends of the housing 421, and push rods 427 are installed at both ends of the slide table 425.

[0101] In this embodiment, heating components 430 are installed at both ends of the propulsion module 420, through holes 428 are opened at both ends of the housing 421, and push rods 427 are installed at both ends of the slide table 425; the outer diameters of the heating components 430 at both ends are different, which can adapt to the inner diameters of the two bearings.

[0102] The push rods 427 at both ends can push the bearings fitted on the heating components 430 at both ends respectively, thus expanding the range of applications.

[0103] Furthermore, the number of push rods 427 at each end is 4 to 6, and they are distributed around the circumference of the heating assembly 430, which can increase the contact area between the push rods 427 and the bearing, resulting in more uniform bearing force and more stable pushing.

[0104] Please see Figure 13 In some embodiments of the present invention, the second assembly assembly 500 may optionally include a work frame 510, a second cross slide 520, a first translation module 530, a tightening member 540, a magnet 550, and a second bolt storage rack 560.

[0105] The working frame 510 is installed on the second lifting arm 320 and can move relative to the frame 1; the second cross slide 520 is installed on the working frame 510; the first translation module 530 is installed on the second cross slide 520; the tightening component 540 is installed on the first translation module 530 and can move relative to the working frame 510; the magnet 550 is installed on the side of the working frame 510 facing the machine body and is used to attract the pressure cap; the second bolt storage rack 560 is installed on the side of the working frame 510 facing the machine body.

[0106] In this embodiment, the second assembly component 500 includes a work frame 510, a second cross slide 520, a first translation module 530, a tightening component 540, a magnet 550, and a second bolt storage rack 560.

[0107] The working frame 510 is installed on the second lifting arm 320, and the working frame 510 can move relative to the frame 1.

[0108] The second cross slide 520 is installed on the working frame 510, and the second cross slide 520 is located outside the working frame 510.

[0109] The first translation module 530 is installed on the second cross slide 520. The first translation module 530 can move relative to the working frame 510 in a first direction and a third direction.

[0110] The tightening component 540 is installed on the first translation module 530 and can move along the second direction on the first translation module 530; after the second cross slide 520 is used in conjunction with the first translation module 530, the tightening component 540 can move relative to the working frame 510.

[0111] Magnet 550 is installed on the side of the work frame 510 facing the machine body. Magnet 550 is used to attract the cap.

[0112] The second bolt storage rack 560 is installed on the side of the working frame 510 facing the machine body. The second bolt storage rack 560 is used to store the bolts required for installing the pressure cap.

[0113] The work frame 510 moves to the bearing and cover supply position along with the second lifting arm 320. The cover is attracted by the magnet 550 and then moved to the machine body mounting port to fasten the installed bearing inside. The second cross slide 520 cooperates with the first translation module 530 to flexibly move the tightening part 540, clamp the bolt and pass the bolt through the through hole of the cover. After the bolt is screwed onto the machine body, the assembly operation of the cover is completed.

[0114] Furthermore, the number of magnets 550 is 4 to 8, and they are evenly distributed according to the area of ​​the working frame 510 abutting the pressure cap, so as to improve the uniformity and stability of adsorption.

[0115] In addition, the second cross slide 520 includes two linear slides, which are arranged perpendicularly to each other. Each linear slide includes a guide rail, a lead screw, a second servo motor, and a lead screw slider. The lead screw slider is used to move the first translation module 530, so that the first translation module 530 can move along the first direction and the third direction.

[0116] In addition, tightening component 540 includes a tightening gun, a wrench quick-change head, and a tightening wrench.

[0117] The tightening gun is installed on the first translation module 530. The quick-change wrench head is detachably installed on the output end of the tightening gun. The quick-change wrench head is used to quickly connect and disconnect with the tightening wrench, so as to realize the quick replacement of tightening wrenches of different specifications. The tightening wrench is installed on the end of the quick-change wrench head away from the tightening gun. The tightening wrench is used to put the bolt on and transmit the tightening torque, so that the bolt passes through the pressure cover and is screwed onto the machine body.

[0118] Optionally, the quick-change wrench head adopts a snap-fit ​​or plug-in connection structure, making the assembly and disassembly of the tightening wrench and the quick-change wrench head simple and quick.

[0119] The tightening gun includes a first servo motor, a torque sensor, and an encoder.

[0120] The first servo motor provides power to the tightening gun. The torque sensor and angle encoder are both electrically connected to the first servo motor. The torque sensor monitors the torque value during the tightening process, and the angle encoder monitors the rotation angle of the output shaft of the first servo motor. The two work together to achieve precise control of the tightening process, ensuring that each bolt is tightened according to the set torque and angle, thus meeting the assembly requirements for bolt tightening.

[0121] Please see Figure 14 Optionally, the first translation module 530 includes a housing 531, a reduction motor 532, a second drive gear, a second driven gear 533, a double-threaded screw 534, and a nut slider 535.

[0122] The housing 531 is mounted on the lead screw slider of the second cross slide 520, and can move along the first direction and the third direction with the lead screw slider.

[0123] The geared motor 532 is mounted on the housing 531, the second drive gear is mounted on the output shaft of the geared motor 532, and the double-threaded screw 534 is rotatably mounted on the housing 531. The double-threaded screw 534 has two threaded sections with opposite thread directions.

[0124] The second driven gear 533 is mounted on the double-threaded screw 534. The second drive gear meshes with the second driven gear 533, and the diameter of the second driven gear 533 is larger than that of the second drive gear. There are two nut sliders 535, which are screwed onto the two threaded sections respectively, and the nut sliders 535 are slidably assembled on the housing 531. Since the two threaded sections rotate in opposite directions, the two nut sliders 535 can move in opposite directions when the double-threaded screw 534 rotates, that is, move closer to each other or move away from each other.

[0125] After the geared motor 532 rotates the second drive gear, the double threaded screw 534 can be rotated at a reduced speed and increased torque through the meshing transmission of the second drive gear and the second driven gear 533. This causes the two tightening parts 540 on the two nut sliders 535 to move synchronously in opposite directions along the second direction, thereby improving the efficiency of bolt installation.

[0126] Please see Figure 6 In some embodiments of the present invention, the assembly station may optionally include a second hoist 610, a second rotating platform 620, a second translation module 630, and an electromagnetic chuck 640.

[0127] The second rotating platform 620 is installed on the second elevator 610; the second translation module 630 is installed on the second rotating platform 620, and the second translation module 630 can be vertically rotated relative to the second elevator 610; the electromagnetic chuck 640 is installed on the second translation module 630, and the electromagnetic chuck 640 can slide relative to the second rotating platform 620. The electromagnetic chuck 640 is used to adsorb bearings or pressure caps.

[0128] In this embodiment, the assembly station also includes a second hoist 610, a second rotating platform 620, a second translation module 630, and an electromagnetic chuck 640.

[0129] The second rotating platform 620 is installed on the second elevator 610, and the second elevator 610 is capable of moving the second rotating platform 620 along a third direction.

[0130] The second translation module 630 is installed on the second rotating platform 620, and the second translation module 630 can be vertically rotated relative to the second elevator 610.

[0131] The electromagnetic chuck 640 is installed on the second translation module 630. The electromagnetic chuck 640 can slide relative to the second rotating platform 620. The position of the electromagnetic chuck 640 can be adjusted by moving along the second direction. The electromagnetic chuck 640 is used to adsorb bearings or pressure caps.

[0132] After the electromagnetic chuck 640 adsorbs the bearing or pressure cap, it can be lifted by the second elevator 610. The second rotating platform 620 can vertically flip the second translation module 630, the electromagnetic chuck 640 and the adsorbed bearing or pressure cap. At the same time, the second translation module 630 moves and adjusts along the second direction until the bearing or pressure cap is moved to the designated standby position.

[0133] Please see Figure 16 Optionally, the second hoist 610 includes a seventh slide rail 612, a third base 613, a ninth motor 614, an eighth gear, and a ninth rack 611.

[0134] The seventh slide rail 612 is vertically installed on the ground, and the third base 613 is slidably installed on the seventh slide rail 612, so that the third base 613 can move along the third direction. The ninth motor 614 is installed on the third base 613, the eighth gear is installed on the output shaft of the ninth motor 614, and the ninth rack 611 is installed on the seventh slide rail 612, and the eighth gear meshes with the ninth rack 611.

[0135] After the ninth motor 614 rotates the eighth gear, the engagement of the eighth gear with the ninth rack 611 provides the third base 613 with the power to move up and down in the third direction.

[0136] Please see Figure 16Optionally, the second rotating platform 620 includes a second drive motor 641, a third drive gear, and a third driven gear 642.

[0137] The support base is fixedly installed on the slide of the second hoist 610. The second drive motor 641 is fixedly installed on the support base. The third drive gear is fixedly installed on the output shaft of the second drive motor 641. The third drive gear can rotate relative to the support base after being driven by the second drive motor 641. The third driven gear 642 is rotatably installed on the support base. The third driven gear 642 meshes with the third drive gear, and the diameter of the third driven gear 642 is larger than that of the third drive gear.

[0138] After the second drive motor 641 rotates the third drive gear, the speed reduction and torque increase of the third drive gear and the third driven gear 642 can drive the second translation module 630 and the electromagnetic chuck 640 to perform a flipping action.

[0139] Please see Figure 15 In some embodiments of the present invention, the second translation module 630 may optionally include an eighth slide rail 634, a tenth motor 631, a ninth gear, a ninth rack 633, and a fourth base 632.

[0140] The eighth slide rail 634 is installed on the second rotating platform 620 and is arranged along the second direction. The fourth base 632 is slidably installed on the eighth slide rail 634 and can move along the second direction.

[0141] The tenth motor 631 is mounted on the fourth base 632, the ninth gear is mounted on the output shaft of the tenth motor 631, the ninth rack 633 is mounted on the eighth slide rail 634, and the ninth gear meshes with the ninth rack 633. The electromagnetic chuck 640 is mounted on the fourth base 632.

[0142] After the tenth motor 631 rotates the ninth gear, the meshing relationship between the ninth gear and the ninth rack 633 provides the fourth base 632 with the power to move, thereby adjusting the position of the electromagnetic chuck 640 in the second direction.

[0143] In some embodiments of the present invention, an assembly line is provided for assembling a stamping machine. Since the assembly line includes an assembly station as described in any of the above technical solutions, it has all the beneficial effects of the assembly station in any of the above technical solutions, thereby completing the assembly operations of the reducer, bearing and gland on the machine body.

[0144] In one embodiment of the present invention, the assembly process of installing the reducer, bearing, and gland onto the machine body using this assembly station is as follows: The machine body enters this assembly station via the conveyor line.

[0145] The AGV (Automated Guided Vehicle) transports the reducer to below the carriage 211. The first lift 210 lowers the slide 212 and carriage 211, bringing them close to the reducer. The lead screws and sliders in the two first cross slides 240 move closer to each other and extend into the bottom of the reducer. As the first lift 210 is lifted, the reducer can be lifted to the mounting port of the machine body. At the same time, the vision camera 280 monitors the relative position of the reducer and the mounting port of the machine body to ensure precise alignment.

[0146] Two quick-change fixtures 230 on the second gantry 220 pick up long bolts from the first bolt storage rack 270, pass them through the reducer through hole and screw them into the machine body to complete the initial positioning. Then, they switch to short bolts for secondary tightening. After removing the long bolts, they add the remaining short bolts to achieve precise assembly of the reducer.

[0147] The AGV transports the bearing to the area below the second elevator 610. It is then lifted and vertically rotated by the second rotating platform 620, the second translation module 630, and the electromagnetic chuck 640, so that the end of the bearing faces the machine body. After that, the first assembly component 400 moves to the bearing via the first lifting arm 310 of the first gantry 300. A heating component 430 is inserted into the inner ring of the bearing. At this time, the electromagnetic chuck 640 is de-energized and loses its magnetic attraction. The bearing is placed on the heating component 430 and is also heated by the heating component 430.

[0148] As the first assembly component 400 approaches the mounting port of the machine body, the first rotating platform 410 drives the propulsion module 420 to rotate horizontally, ultimately aligning the bearing with the mounting port. Then, through the push of the propulsion module 420, the bearing with an enlarged inner diameter can be installed between the output shaft of the reducer and the mounting port, completing the bearing assembly.

[0149] The second assembly component 500 is moved to the cap receiving point via the second lifting arm 320 of the first gantry 300, that is, the side of the first gantry 300 away from the lifting component 200. The AGV trolley transports the cap to the area below the second elevator 610, and lifts and vertically flips it via the second rotating platform 620, the second translation module 630, and the electromagnetic chuck 640, so that the cap faces away from the machine body and aligns with the magnet 550. At this time, the electromagnetic chuck 640 is de-energized and loses its magnetic attraction, and the cap is attracted to the magnet 550. Then the second rotating platform 620, the second translation module 630, and the electromagnetic chuck 640 are reset downwards.

[0150] After the second assembly component 500 moves the end cover to press against the mounting port, the coordinated movement of the second cross slide 520 and the first translation module 530 causes the tightening component 540 to take the bolt from the second bolt storage rack 560. The bolt passes through the through hole on the cover and is screwed to the body. Then the second assembly component 500 resets, completing the assembly of the cover.

[0151] The entire process utilizes the coordinated operation of core components such as the lifting assembly 200, the first gantry 300, the first assembly assembly 400, and the second assembly assembly 500 to achieve fully automated assembly of the reducer, bearings, and gland, replacing manual operation and improving assembly accuracy and consistency.
