[0002] In the field of motor manufacturing and assembly, the press-fitting of end cap oil seals is a critical process that affects the long-term reliability and performance of motors. The oil seal (usually a skeleton seal ring or a rubber seal ring) is responsible for sealing the gap between the motor shaft and the end cap, preventing internal lubricating oil (grease) leakage, and blocking external contaminants such as dust and moisture from entering. The quality of its press-fitting directly determines the motor's sealing effect, service life, and failure rate.

[0003] In existing technologies, the oil seal pressing process typically relies on manual operation, including placing, positioning, aligning, and pressing the oil seal against the motor end cover.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention achieves fully mechanized operation from end cover and oil seal feeding, positioning, angle adjustment, pressing to finished product unloading through a moving limiting component, an end cover transfer positioning component, an oil seal transfer positioning component, and a finished product unloading component. This significantly reduces manual intervention, improves the pressing efficiency of motor end cover oil seals, and also reduces the product error rate.

[0016] 2. This invention uses a longitudinal ball screw linear module to drive the moving seat, combined with a baffle and a slotted photoelectric switch, to ensure the accurate movement and stopping position of the end cap and oil seal between each workstation. The oil seal moving mechanism uses lateral and vertical cylinders to ensure precise alignment between the oil seal and the pressure head.

[0017] 3.

This solves the assembly problem caused by the asymmetrical structure of the end cap and improves the equipment's adaptability to complex workpieces.

[0018] 3. This invention integrates an oiling mechanism into the oil seal feeding process, using a centrifugal pump to evenly spray lubricating oil onto the oil seal surface, automating the lubrication process and ensuring the oil seal receives adequate lubrication before pressing. The design of the strainer and oil collection cover allows for the collection of excess lubricating oil, ensuring both the pressing process requirements and preventing environmental pollution.

[0019] 4. Before pressing, the present invention uses a third cylinder to drive the positioning frame to limit the end cap protrusion. After pressing, when the press head is lifted, the positioning frame can prevent the end cap from being lifted by the oil seal friction, ensuring that the workpiece is reliably kept in the end cap positioning bowl after pressing, thus improving the stability and reliability of the equipment operation.

[0020] 5. This invention achieves workpiece in-situ detection, position control, and process interlocking by setting up photoelectric sensors (through-beam type, slot type, etc.) at multiple locations, avoiding misoperation or workpiece omission. The application of pressure and torque sensors can monitor pressing force and rotational torque in real time, ensuring that process parameters are controlled and improving operational safety and process reliability.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1-13 The present invention provides a motor end cap oil seal pressing equipment, including a worktable 1, a moving limiting component 2 for transporting the oil seal and end cap to the coaxial center on the top surface of the worktable 1, an end cap transfer positioning component 3 for transferring the position of the end cap on the top surface of the worktable 1, an oil seal transfer positioning component 4 for transferring the position of the oil seal on the top surface of the worktable 1, and a finished product discharge component 5 for conveying the pressed and formed finished product on the top surface of the worktable 1. The movable limiting assembly 2 includes a fixed frame 201 fixedly connected to the top surface of the workbench 1. A longitudinal ball screw linear module 202 is fixedly connected to the top surface of the workbench 1 by bolts. The longitudinal ball screw linear module 202 is located between the fixed frames 201. A movable seat 203 is fixedly connected to the top surface of the movable table of the longitudinal ball screw linear module 202 by bolts. An end cap positioning bowl 204 is fixedly connected to the positioning side of the movable seat 203 by bolts. The end cap is located inside the end cap positioning bowl 204. An oil seal moving mechanism 210 is provided on the side of the top surface of the movable seat 203 away from the end cap positioning bowl 204. A mounting frame 205 is fixedly connected to the top surface of the fixed frame 201 by bolts. A hydraulic cylinder 206 is mounted on the top surface of the mounting frame 205. A pressure head 207 is fixedly connected to the piston rod of the hydraulic cylinder 206.

[0037] The oil seal moving mechanism 210 includes a transverse cylinder that is fixedly connected to the top surface of the moving seat 203 by bolts. The piston rod of the transverse cylinder is fixedly connected to a vertical cylinder. The piston rod of the vertical cylinder is fixedly connected to a pressure sensor 211. The force-bearing end of the pressure sensor 211 is fixedly connected to an oil seal lifting block 212. The oil seal is located inside the oil seal lifting block 212.

[0038] The bottom surface of the fixed frame 201 is fixedly connected with several baffles 208 along the axis by bolts. The position of each baffle 208 corresponds to the end cover placement position, the oil seal placement position, the end cover and oil seal pressing position, and the finished product removal position. The bottom surface of the movable seat 203 is located on one side of the baffle 208 and is equipped with a slotted photoelectric switch 209 by bolts. The baffle 208 and the slotted photoelectric switch 209 cooperate with each other.

[0039] When the oil seal of the motor end cover needs to be press-fitted, the oil seal is first placed inside the top of the oil seal lifting block 212 by the oil seal transfer positioning component 4. The oil seal lifting block 212 limits the oil seal. Then, the motor inside the longitudinal ball screw linear module 202 is started. The motor of the longitudinal ball screw linear module 202 will drive the moving table to move through the screw. When the moving table moves, it will drive the moving seat 203 to move until the end cover positioning bowl 204 moves to the appropriate position. At this time, the baffle 208 and the slotted photoelectric switch 20 The 9 cylinders work together to stop the longitudinal ball screw linear module 202. At this time, the transverse cylinder of the oil seal moving mechanism 210 is activated. The transverse cylinder pushes the vertical cylinder to move towards the pressure head 207 until the oil seal and the pressure head 207 are on the same vertical axis. Then the vertical cylinder is activated. The vertical cylinder lifts the oil seal through the oil seal lifting block 212, so that the oil seal is fitted onto the surface of the pressure head 207, thereby achieving the positioning of the oil seal. Then the piston rods of the vertical cylinder and the transverse cylinder are retracted in sequence to avoid obstructing the operation of other components.

[0040] While positioning the oil seal, the end cap is placed inside the end cap positioning bowl 204. Then, the longitudinal ball screw linear module 202 is restarted. The longitudinal ball screw linear module 202 will move towards the mounting bracket 205. During this movement, the components inside the end cap transfer positioning assembly 3 will adjust the angle of the end cap until the end cap positioning bowl 204 moves to a position coaxial and perpendicular to the pressure head 207. At this point, the slotted photoelectric switch 209 and the baffle 208 will cooperate to stop the longitudinal ball screw linear module 202 from running. Then, it is restarted. The piston rod of the hydraulic cylinder 206 pushes the pressure head 207 toward the end cover. Because the end cover has a protrusion, a protruding contour groove is provided on the bottom surface of the pressure head 207 to avoid interference caused by the protrusion. When the pressure head 207 is inserted into the end cover, the oil seal will also be inserted into the end cover, thereby realizing the pressing of the end cover and the oil seal. After pressing, the finished product will move again toward the finished product picking position by the movement of the moving seat 203. Then, through the cooperation of the baffle 208 and the slotted photoelectric switch 209, the finished product will stop at the finished product picking position, and then the finished product will be transferred by the finished product discharge assembly 5.

[0041] It should be noted that in this application, the slotted photoelectric switch 209 is model EE-SX671. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0042] In this invention, the end cap transfer and positioning assembly 3 includes an end cap transmission line 301 fixedly connected to the top surface of the workbench 1 by bolts. The end cap is placed on the top surface of the end cap transmission line 301. An end cap transfer mechanism 302 is fixedly connected to the top surface of the workbench 1 by bolts. The end cap transfer mechanism 302 is located on one side of the end cap transmission line 301. The clamping cylinder of the end cap transfer mechanism 302, the end cap positioning bowl 204, and the end cap of the end cap transmission line 301 are all on the same axis. The end cap transfer mechanism 302 includes a bracket fixedly connected to the top surface of the workbench 1 by bolts. A vertical cylinder slide is fixedly connected to the side of the bracket by bolts. A finger cylinder is fixedly connected to the piston rod of the vertical cylinder slide.

[0043] The end cap transfer positioning assembly 3 also includes an end cap angle adjustment mechanism. The end cap angle adjustment mechanism includes a positioning bracket 303 fixedly connected by bolts. A first cylinder 304 is fixedly connected to one side of the positioning bracket 303. A first motor 305 is slidably connected to the side of the positioning bracket 303 away from the first cylinder 304 via a guide rail. A torque sensor 307 is fixedly connected to the output shaft of the first motor 305 via a coupling. Two force plates 306 are fixedly connected to the bottom end of the torque sensor 307 by bolts. The two force plates 306 are staggered. Two second cylinders 308 are symmetrically fixedly connected to the surface of the positioning bracket 303 by bolts. A limit plate 309 is fixedly connected to the piston rod of each second cylinder 308. The two limit plates 309 are staggered.

[0044] The top surface of the fixed frame 201 is symmetrically fixedly connected with two third cylinders 310 by bolts. The two third cylinders 310 are located on both sides of the movable seat 203, and the piston rods of the two third cylinders 310 correspond to each other. The piston rod of each third cylinder 310 is fixedly connected with a positioning frame 311. The two positioning frames 311 are on the same axis as the pressure head 207.

[0045] When the end cap needs to be placed, first place the end cap on the top surface of the end cap transmission line 301, then start the motor of the end cap transmission line 301. The belt of the end cap transmission line 301 will drive the end cap to move until the end cap moves to the other end of the end cap transmission line 301. Because a through-beam photoelectric sensor is installed at the other end of the end cap transmission line 301, when the end cap moves between the through-beam photoelectric sensor, it blocks the light from the through-beam photoelectric sensor. At this time, the end cap transmission line 301 will stop running. At this time, the end cap and the finger cylinder of the end cap transfer mechanism 302 are on the same vertical axis. Then, start the finger cylinder of the end cap transfer mechanism 302 to open the gripper of the finger cylinder, and then start... The vertical cylinder slide of the end cap transfer mechanism 302 pushes the finger cylinder towards the end cap until the end cap is between the two grippers of the finger cylinder. Then, the finger cylinder clamps the end cap and the vertical cylinder slide lifts the end cap. When the end cap is lifted, the light from the through-beam photoelectric sensor is no longer blocked. The end cap transmission line 301 will run again to transfer the new end cap to the area below the finger cylinder. Then, the moving seat 203 moves the end cap positioning bowl 204 to the area below the finger cylinder holding the end cap. Finally, the vertical cylinder slide and the finger cylinder work together to place the end cap inside the end cap positioning bowl 204, thus realizing the transfer and placement of the end cap.

[0046] After the end cap is placed, the end cap positioning bowl 204 is moved towards the mounting bracket 205 via the movable seat 203 until it is directly below the first motor 305. At this point, the movable seat 203 stops moving due to the cooperation of the baffle 208 and the slotted photoelectric switch 209. The end cap positioning bowl 204 and the output shaft of the first motor 305 are now aligned vertically. Then, the two second cylinders 308 are activated. The piston rods of the two second cylinders 308 drive the two limiting plates 309 towards the end cap positioning bowl 204 until they are in contact with the end cap. At this point, the edge protrusions of the end cap are located on either side of the two limiting plates 309. Because the two limiting plates 309 are not located on the axis of the end cap, when the first cylinder 304 is activated, the piston rod of the first cylinder 304... The first motor 305 will move downwards until the two force plates 306 are in contact with the end cap. Then, the first motor 305 will be started, and the first motor 305 will drive the two force plates 306 to rotate through the torque sensor 307. Since the two force plates 306 are not located on the axis of the end cap, when the two force plates 306 rotate around the output shaft of the first motor 305, the force plates 306 will be in contact with the two protrusions of the end cap until the two protrusions are in contact with the two limiting plates 309 respectively. At this time, due to the contact, the torque sensor 307 will stop the first motor 305 from rotating due to the force, thus realizing the adjustment of the end cap position. Then, the first cylinder 304 will drive the force plates 306 to move upwards, and then the two limiting plates 309 will be retracted, thus completing the adjustment of the end cap angle.

[0047] After the end cap angle is adjusted, the moving seat 203 moves the end cap positioning bowl 204 toward the mounting bracket 205 again until the end cap positioning bowl 204 and the pressure head 207 are on the same vertical axis. At this time, due to the cooperation of the baffle 208 and the slotted photoelectric switch 209, the moving seat 203 will stop moving. Then, the two third cylinders 310 are activated, and the two positioning frames 311 move toward the end cap protrusion until the two positioning frames 311 limit the end cap protrusion. Then, the hydraulic cylinder 206 presses the oil seal into the end cap. When the pressure head 207 is pulled up, the two positioning frames 311 limit the end cap to prevent the end cap from being moved by friction.

[0048] In this invention, the oil seal transfer and positioning assembly 4 includes an oil seal feeder 401 fixedly connected to the top surface of the workbench 1, and an oil seal transfer mechanism 407 fixedly connected to the top surface of the workbench 1 by bolts. The finger cylinder of the oil seal transfer mechanism 407 and the oil seal placement position are on the same vertical axis.

[0049] The oil seal transfer mechanism 407 includes a bracket fixedly connected to the top surface of the worktable 1 by bolts, and a horizontal ball screw linear module is mounted on the surface of the bracket. A vertical ball screw linear module is fixedly connected to the moving table surface of the horizontal ball screw linear module by bolts, and a finger cylinder is fixedly connected to the moving table surface of the vertical ball screw linear module by bolts.

[0050] The oil seal transfer and positioning assembly 4 also includes an oil seal oiling mechanism; the oil seal oiling mechanism includes a mesh 402 fixedly connected to the outlet of the oil seal feeder 401, a protective shell is provided above the outlet of the oil seal feeder 401, and the protective shell is fixedly connected to the housing of the oil seal feeder 401 by bolts, and an oil inlet pipe 403 is provided inside the protective shell, one end of the oil inlet pipe 403 penetrates the protective shell and is connected to the centrifugal pump 404, an oil collection cover 405 is provided below the outlet of the oil seal feeder 401, the oil collection cover 405 is located below the mesh 402, an oil outlet pipe 406 is fixedly connected to the bottom end of the oil collection cover 405, and the end of the oil outlet pipe 406 away from the oil collection cover 405 is connected to an external oil storage tank.

[0051] When the oil seal feeder 401 transports the oil seal to the outlet position, the oil seal will block the light of the through-beam photoelectric switch, thus stopping the oil seal from moving. First, the horizontal ball screw linear module is activated to make the finger cylinder and the oil seal the same vertical axis. Then, the vertical ball screw linear module is activated to make the two grippers of the finger cylinder located at the axis of the oil seal. Then, the two grippers of the finger cylinder are activated to open the two grippers to limit the oil seal. Then, the oil seal is placed inside the oil seal lifting block 212 through the horizontal ball screw linear module and the vertical ball screw linear module, thus realizing the transfer and positioning of the oil seal.

[0052] When the oil seal moves from the inside of the oil seal feeder 401 toward the discharge port, it passes through the strainer 402. The centrifugal pump 404 draws external lubricating oil and sprays it onto the surface of the oil seal through the oil inlet pipe 403. The lubricating oil flows into the inside of the first motor 305 through the strainer 402, and is introduced into the inside of the oil outlet pipe 406 through the oil collection cover 405. It then enters the inside of the external oil storage tank through the oil outlet pipe 406, thus realizing the oiling of the oil seal and the recovery of the lubricating oil.

[0053] It should be noted that the through-beam photoelectric switch in this application is model E3Z-T61NO. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0054] It should be noted that in this application, the ball screw linear module model is SGX. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0055] In this invention, the finished product discharge assembly 5 includes a finished product transfer mechanism 501 that is fixedly connected to the top surface of the workbench 1 by bolts. The finger cylinder of the finished product transfer mechanism 501 is on the same vertical line as the finished product picking position. The top surface of the workbench 1 is fixedly connected to a finished product conveying line 502 by bolts. The finished product conveying line 502 is located on one side of the fixed frame 201. The finished product transfer mechanism 501 includes a bracket and a horizontal cylinder slide that is fixedly connected to the side of the bracket by bolts. The piston rod of the horizontal cylinder slide is fixedly connected to a vertical cylinder slide. The piston rod of the vertical cylinder slide is fixedly connected to a finger cylinder by bolts.

[0056] After the oil seal and end cap are pressed together, the moving seat 203 is activated again to position the finished product in the finished product picking position. Then, the transverse cylinder slide in the finished product conveyor line 502 is activated. The transverse cylinder slide will align the finger cylinder with the finished product on the same vertical axis. Then, the finger cylinder is activated to open its two grippers. Subsequently, the vertical cylinder slide is activated so that the grippers of the finger cylinder are positioned on both sides of the finished product. The finished product is gripped by the finger cylinder. Then, the finished product is transferred to the surface of the finished product conveyor line 502 by the vertical and transverse cylinder slides. Finally, the finished product is conveyed away by the finished product conveyor line 502, thus realizing the transfer of the finished product.

[0057] It should be noted that the model of the conveyor line in this application is TF-SSD. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0060] It should be noted that in this application, the hydraulic cylinder is an actuator in the hydraulic system, which realizes the telescopic function by cooperating with the hydraulic system, and realizes the precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with magnetic switches, proximity switches or photoelectric switches. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0061] It should be noted that in this application, the cylinder is a power actuator that converts the pressure energy of compressed air into mechanical energy. By controlling the gas in and out, it drives the piston to perform linear reciprocating motion. It can be used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the extension and retraction displacement of the cylinder piston rod. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0062] The present invention is used in the following steps: S1: First, place the oil seal inside the oil seal feeder 401. Start the oil seal feeder 401, and the oil seal will move towards the discharge port of the oil seal feeder 401. As the oil seal moves from inside the oil seal feeder 401 towards the discharge port, it will pass through the strainer 402. The centrifugal pump 404 will draw external lubricating oil and spray it onto the surface of the oil seal through the oil inlet pipe 403. The lubricating oil will flow into the first motor 305 through the strainer 402, and be guided into the oil outlet pipe 406 through the oil collection cover 405. Finally, it will enter the external oil storage tank through the oil outlet pipe 406, thus realizing the oiling of the oil seal and the recovery of the lubricating oil. With the continuous operation of 401, after the oil seal feeder 401 transports the oil seal to the discharge port, the oil seal will block the light of the through-beam photoelectric switch, thus stopping the oil seal from moving. First, the horizontal ball screw linear module is activated to make the finger cylinder and the oil seal the same vertical axis. Then, the vertical ball screw linear module is activated to make the two grippers of the finger cylinder located at the axis of the oil seal. Then, the two grippers of the finger cylinder are activated to open the two grippers to limit the oil seal. Then, the oil seal is placed inside the oil seal support block 212 through the horizontal ball screw linear module and the vertical ball screw linear module, thus realizing the transfer and positioning of the oil seal. S2: The oil seal is limited by the oil seal lifting block 212, and then the motor inside the longitudinal ball screw linear module 202 is started. The motor of the longitudinal ball screw linear module 202 will drive the moving table to move through the screw, and the moving table will drive the moving seat 203 to move until the end cover positioning bowl 204 moves to the appropriate position. At this time, the baffle 208 and the slotted photoelectric switch 209 will cooperate with each other to stop the longitudinal ball screw linear module 202 from running. At this time, the horizontal cylinder of the oil seal moving mechanism 210 is started. The horizontal cylinder pushes the vertical cylinder to move towards the pressure head 207 until the oil seal and the pressure head 207 are on the same vertical axis. Then the vertical cylinder is started. The vertical cylinder will lift the oil seal through the oil seal lifting block 212 so that the oil seal is sleeved on the surface of the pressure head 207, thereby realizing the positioning of the oil seal. Then the piston rods of the vertical cylinder and the horizontal cylinder are retracted in sequence to avoid obstructing the operation of other components. S3: As the oil seal is discharged through the oil seal feeder 401, the end cap is placed on the top surface of the end cap conveyor 301. Then, the motor of the end cap conveyor 301 is started, and the belt of the end cap conveyor 301 will drive the end cap to move until the end cap moves to the other end of the end cap conveyor 301. Because a through-beam photoelectric sensor is installed at the other end of the end cap conveyor 301, when the end cap moves between the through-beam photoelectric sensor, it blocks the light from the through-beam photoelectric sensor. At this time, the end cap conveyor 301 will stop running. At this time, the end cap and the finger cylinder of the end cap transfer mechanism 302 are on the same vertical axis. Then, the finger cylinder of the end cap transfer mechanism 302 is started, causing the gripper of the finger cylinder to open, and then the end cap is started. The vertical cylinder slide of the cap transfer mechanism 302 pushes the finger cylinder toward the end cap until the end cap is between the two grippers of the finger cylinder. Then, the finger cylinder clamps the end cap and the vertical cylinder slide lifts the end cap. When the end cap is lifted, the light of the through-beam photoelectric sensor is no longer blocked. The end cap transmission line 301 will run again to transfer the new end cap to the bottom of the finger cylinder. Because the oil seal is on the surface of the pressure head 207, the moving seat 203 will move the end cap positioning bowl 204 to the bottom of the finger cylinder holding the end cap. Then, the end cap is placed inside the end cap positioning bowl 204 through the cooperation of the vertical cylinder slide and the finger cylinder, thus realizing the transfer and placement of the end cap. S4: After the end cap is placed, the end cap positioning bowl 204 is moved towards the mounting bracket 205 via the movable seat 203 until it is directly below the first motor 305. At this point, the movable seat 203 stops moving due to the cooperation of the baffle 208 and the slotted photoelectric switch 209. At this time, the end cap positioning bowl 204 and the output shaft of the first motor 305 are on the same vertical line. Then, the two second cylinders 308 are started. The piston rods of the two second cylinders 308 will drive the two limiting plates 309 to move towards the end cap positioning bowl 204 until the two limiting plates 309 are in contact with the end cap. At this time, the edge protrusions of the end cap will be located on both sides of the two limiting plates 309. Since the two limiting plates 309 are not located on the axis of the end cap, when the first cylinder 304 is started, the piston of the first cylinder 304... The lever drives the first motor 305 to move downwards until the two force plates 306 are in contact with the end cap. Then the first motor 305 is started, and the first motor 305 drives the two force plates 306 to rotate through the torque sensor 307. Since the two force plates 306 are not located on the axis of the end cap, when the two force plates 306 rotate around the output shaft of the first motor 305, the force plates 306 will be in contact with the two protrusions of the end cap until the two protrusions are in contact with the two limiting plates 309 respectively. At this time, due to the contact, the torque sensor 307 will stop the first motor 305 from rotating due to the force, thus realizing the adjustment of the end cap position. Then the first cylinder 304 drives the force plates 306 to move upwards, and then the two limiting plates 309 are retracted, thus completing the adjustment of the end cap angle. S5: After the end cap angle adjustment is completed, the moving base 203 again moves the end cap positioning bowl 204 towards the mounting bracket 205 until the end cap positioning bowl 204 and the pressure head 207 are on the same vertical axis. At this time, due to the cooperation of the baffle 208 and the slotted photoelectric switch 209, the moving base 203 will stop moving. Then, the two third cylinders 310 are activated, and the two positioning frames 311 will move towards the end cap protrusion until the two positioning frames 311 are aligned with the end cap protrusion. The limit switch is activated, and then the hydraulic cylinder 206 is started. The piston rod of the hydraulic cylinder 206 will push the pressure head 207 towards the end cover. Because there is a protrusion in the inner cavity of the end cover, a protruding contour groove is opened on the bottom surface of the pressure head 207 to avoid interference caused by the protrusion. When the pressure head 207 is inserted into the end cover, the oil seal will be inserted into the end cover, thereby realizing the pressing of the end cover and the oil seal. When the pressure head 207 is pulled up, the two positioning frames 311 limit the end cover to prevent the end cover from being driven by friction. S6: After the oil seal and end cap are pressed together, start the moving seat 203 again to position the finished product in the finished product picking position. Then start the transverse cylinder slide in the finished product conveyor line 502. The transverse cylinder slide will make the finger cylinder and the finished product the same vertical axis. Then start the finger cylinder to open the two grippers of the finger cylinder. Then start the vertical cylinder slide so that the grippers of the finger cylinder are on both sides of the finished product. The finished product is clamped by the finger cylinder. Then the finished product is transferred to the surface of the finished product conveyor line 502 by the vertical cylinder slide and the transverse cylinder slide. Then the finished product is transported away by the finished product conveyor line 502, thus realizing the transfer of the finished product.
