Description

Technical Field

[0001] This application relates to the field of dynamic balancing testing technology, and in particular to a dynamic balancing testing weight removal device. Background Technology

[0002] Dynamic balancing testing is a technical process for detecting and correcting the dynamic balance of rotating workpieces (such as motor rotors). Its purpose is to eliminate vibration, noise and equipment damage caused by uneven mass distribution.

[0003] In existing technologies, testing equipment and weight-removal equipment are typically used to test and remove weight from rotating workpieces. During operation, the rotating workpiece is first sent to the testing equipment for dynamic balancing testing, and then the tested rotating workpiece is sent to the weight-removal equipment for weight removal. After weight removal, the rotating workpiece is sent back to the testing equipment for dynamic balancing retest.

[0004] Regarding the aforementioned solutions, the inventors believe that the following drawbacks exist: First, the testing equipment and the deweighting equipment are set up independently, and they need to be transported over a long distance by a belt conveyor, which greatly reduces the efficiency of dynamic balancing testing and deweighting of rotating workpieces; Second, the independently set testing equipment and deweighting equipment greatly increase the operating cost and floor space of the equipment. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this application provides a highly efficient dynamic balancing test weight removal device.

[0006] The dynamic balancing test weight removal device provided in this application adopts the following technical solution:

[0007] A dynamic balancing test weight removal device includes a base, a lifting and rotatable conveying mechanism mounted on the base, and a drive mechanism for driving the conveying mechanism. The conveying mechanism has multiple processing stations arranged around its periphery. Each of the multiple processing stations is equipped with a conveying mechanism, at least one testing mechanism, and at least one weight removal mechanism. The conveying mechanism can pass through the multiple processing stations sequentially during its movement.

[0008] By adopting the above technical solution, the conveying mechanism, at least one testing mechanism, and at least one de-weighing mechanism are respectively arranged on multiple processing stations, so that each mechanism can receive the rotating workpiece and test and de-weigh it during the movement of the handling mechanism, without the need for long-distance transportation, which greatly improves the efficiency of dynamic balance testing and de-weighing. At the same time, the conveying mechanism, at least one testing mechanism, and at least one de-weighing mechanism can be integrated into a whole structure through the handling mechanism, which not only saves the cost of use, but also reduces the footprint of the equipment.

[0009] Preferably, the plurality of processing stations include a loading / unloading station, a preliminary measurement station, a first de-weighting station, a second de-weighting station, and a re-measurement station arranged sequentially around the circumference of the conveying mechanism. The conveying mechanism is located at the loading / unloading station. There are two testing mechanisms, which are respectively located at the preliminary measurement station and the re-measurement station. There are two de-weighting mechanisms, which are respectively located at the first de-weighting station and the second de-weighting station.

[0010] By adopting the above technical solution, the rotating workpiece can quickly reach the loading / unloading station, the initial measurement station, the first de-weighting station, the second de-weighting station, and the re-measurement station during the movement of the conveying mechanism. Then, the loading / unloading process, the two de-weighting processes, and the two testing processes are completed respectively, which effectively improves the efficiency of dynamic balance testing and de-weighting.

[0011] Preferably, the testing mechanism includes a testing component and a driving component. The testing component includes a testing frame, a movable swing frame disposed within the testing frame, a spring disposed between the testing frame and the swing frame, and a sensing module disposed on the side of the swing frame. The direction of movement of the swing frame is perpendicular to the arrangement direction of the testing component and the driving component.

[0012] By adopting the above technical solution, the swing frame can accurately transmit the unbalance of the rotating workpiece to the sensing module during its swing, effectively improving the accuracy of dynamic balancing test.

[0013] Preferably, the swing frame includes two opposing second frames and a support plate connected to the two second frames at both ends. A clamping assembly is provided between the two second frames. The clamping assembly includes two clamping plates that can be opened or closed relative to each other and a first driving member for driving the two clamping plates to move. The movement direction of the two clamping plates is perpendicular to the arrangement direction of the two second frames. When the two clamping plates are closed relative to each other, a first gap is formed between the two clamping plates, and the support plate is movably accommodated in the first gap.

[0014] By adopting the above technical solution, the two clamping plates can clamp the rotating workpiece without affecting the movement of the bearing plate when they are closed relative to each other, thereby further improving the testing accuracy of dynamic balance.

[0015] Preferably, the weight-removing mechanism includes a load-bearing component, a weight-removing component, and a dust-collecting component. The weight-removing component includes a spindle seat movably disposed along a direction close to or away from the load-bearing component, a second driving member for driving the spindle seat to move, a drill bit rotatable about its own axis and disposed within the spindle seat, and a third driving member for driving the drill bit to rotate. The axial direction of the drill bit is the same as the moving direction of the spindle seat. The dust-collecting component includes a dust-collecting pipe movably disposed along the axial direction of the drill bit. The end of the dust-collecting pipe near the spindle seat has a dust-collecting part. The dust-collecting part has a dust-collecting port and a sliding hole on opposite sides. The drill bit is slidably disposed in the sliding hole along its axial direction.

[0016] By adopting the above technical solution, when the drill bit is drilling a rotating workpiece to remove weight, the dust suction port can come into contact with the rotating workpiece and suck out the generated debris, preventing debris from flying and causing damage to the physical and mental health of workers.

[0017] Preferably, the support assembly includes a support base, an adjustment base movably disposed along a direction close to or away from the support base, a fourth driving member for driving the adjustment base to move, and an adjustment block disposed at one end of the adjustment base away from the support base.

[0018] By adopting the above technical solution, when the conveying mechanism places the rotating workpiece on the carrier, the adjusting block can push the rotating workpiece during the movement of the adjusting seat, thereby adjusting the loading position of the rotating workpiece and preventing excessive weight loss error due to the loading deviation of the rotating workpiece.

[0019] Preferably, the weight-removing mechanism further includes a clamping assembly, which includes a clamping seat movably disposed along a direction close to or away from the bearing assembly, a fifth driving member for driving the clamping seat to move, a clamping rod rotatably disposed on the clamping seat, and a sixth driving member for driving the clamping rod to rotate, wherein the rotation direction of the clamping rod is perpendicular to the movement direction of the clamping seat.

[0020] By adopting the above technical solution, the clamping rod can clamp onto the rotating workpiece during its rotation, thereby preventing the rotating workpiece from shifting during the weight removal process and effectively improving the weight removal accuracy.

[0021] Preferably, the weight-removing mechanism further includes a corner assembly, which includes a corner seat, a first gripper module rotatable about its own axis and disposed on the corner seat, and a seventh driving member for driving the first gripper module to rotate. The corner seat has a rotating cavity, and a shaft cylinder is coaxially disposed on the first gripper module. The shaft cylinder is rotatably inserted into the rotating cavity.

[0022] By adopting the above technical solution, the first gripper module can drive the rotating workpiece to rotate during the weight removal process, so as to drill holes at different positions of the rotating workpiece.

[0023] Preferably, the conveying mechanism has a defective station at the end of its conveying direction. The defective station is equipped with a first top-feeding assembly. A collecting assembly is provided above the first top-feeding assembly. The collecting assembly includes a collecting seat, a first conveyor belt module and a guiding module disposed on the collecting seat. Multiple first stops are spaced apart on the first conveyor belt module along its conveying direction. The guiding module includes two guide plates hinged to the front end of the first conveyor belt module and a limiting plate disposed below the guide plates. The extension direction of the rotation axis of the guide plates is perpendicular to the conveying direction of the first conveyor belt module. The multiple first stops can pass between the two guide plates in sequence. The first top-feeding assembly includes a liftable first top-feeding frame and an eighth driving member for driving the first top-feeding frame to lift. The first top-feeding frame is located below the guiding module. A second gap is formed between the two guide plates. The first top-feeding frame is liftably inserted into the second gap.

[0024] By adopting the above technical solution, the first top material rack can collect defective products during its lifting process through the cooperation of the baffle plate and the first stop block, eliminating the need for manual removal of defective products and effectively improving the collection efficiency of defective products.

[0025] Preferably, the conveying mechanism includes a lifting and rotating shaft mounted on the base, a conveying frame coaxially sleeved on the upper end of the shaft, and multiple connecting ends located on the outer periphery of the conveying frame. Each connecting end is provided with a second gripper module, which is slidably arranged in the vertical direction. A buffer is provided between the second gripper module and the upper part of the connecting end.

[0026] By adopting the above technical solution, the second gripper module can compress the buffer component backward to achieve buffering when handling the rotating workpiece, thus preventing damage to the rotating workpiece due to rigid impact.

[0027] In summary, the present invention has at least one of the following beneficial technical effects:

[0028] By arranging the conveying mechanism, at least one testing mechanism, and at least one de-weighing mechanism on multiple processing stations, each mechanism can receive and test rotating workpieces and de-weigh them during the movement of the conveying mechanism, eliminating the need for long-distance transportation and greatly improving the efficiency of dynamic balancing testing and de-weighing. At the same time, the conveying mechanism, at least one testing mechanism, and at least one de-weighing mechanism can be integrated into a single structure through the conveying mechanism, which not only saves on operating costs but also reduces the footprint of the equipment.

[0040] 100. Rotating workpiece. Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0042] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0043] See Figure 1 As shown, a dynamic balancing test weight removal device includes a base 1, a lifting and rotatable conveying mechanism 2 mounted on the base 1, and a drive mechanism 3 for driving the conveying mechanism 2. The base 1 is horizontally positioned, and the rotation axis of the conveying mechanism 2 extends vertically.

[0044] Five processing stations are arranged around the transport mechanism 2. These five processing stations include a loading / unloading station, a preliminary measurement station, a first de-weighting station, a second de-weighting station, and a re-measurement station, arranged sequentially around the circumference of the transport mechanism 2. The loading / unloading station is equipped with a conveying mechanism 4, which is used to transport the rotating workpiece 100. The preliminary measurement station and the re-measurement station are both equipped with testing mechanisms 5, which are used to perform preliminary measurement of the rotating workpiece 100 before de-weighting and re-measurement after de-weighting, respectively. The first de-weighting station and the second de-weighting station are both equipped with de-weighting mechanisms 6, which are used to de-weight the ends and sides of the rotating workpiece 100, respectively. The transport mechanism 2 is used to drive the workpiece sequentially through the loading / unloading station, the preliminary measurement station, the first de-weighting station, the second de-weighting station, and the re-measurement station to complete the testing and de-weighting of the rotating workpiece 100.

[0045] In this way, each mechanism can receive and test the rotating workpiece 100 and remove weight during the movement of the handling mechanism 2, without the need for long-distance transportation, which greatly improves the efficiency of dynamic balance testing and weight removal. At the same time, the conveying mechanism 4, the two testing mechanisms 5 and the two weight removal mechanisms 6 can be integrated into a whole structure through the handling mechanism 2, which not only saves the cost of use, but also reduces the footprint of the equipment.

[0046] In this embodiment, combined with Figure 5 As shown, the conveying mechanism 2 includes a conveying seat 26, a lifting and rotatable shaft 21 mounted on the conveying seat 26, a conveying frame 22 coaxially sleeved on the upper end of the shaft 21, and five connecting ends 23 located on the outer periphery of the conveying frame 22. The shaft 21 extends vertically, and each connecting end 23 is provided with a second gripper module 24. The second gripper module 24 is slidably mounted vertically, and a buffer 25, which is a spring, is provided between the second gripper module 24 and the upper part of the connecting end 23. The driving mechanism 3 includes a cylinder for driving the shaft 21 to lift and lower, and a motor for driving the shaft 21 to rotate. The output end of the cylinder is coaxially connected to the shaft 21, and the output end of the motor is drively connected to the shaft 21.

[0047] During transport, the second gripper module 24 on the five connecting ends 23 can synchronously transport the rotating workpiece 100 on the five processing stations, so that each mechanism on the five processing stations can synchronously receive the rotating workpiece 100 and complete the corresponding processing steps, effectively improving the testing and weight removal efficiency of the rotating workpiece 100; at the same time, the second gripper module 24 can compress the buffer 25 backward to achieve buffering when transporting the rotating workpiece 100, preventing the rotating workpiece 100 from being damaged by rigid impact.

[0048] In this embodiment, combined with Figure 2As shown, the testing mechanism 5 includes a base 54, on which a testing component 51 and a driving component 52 are disposed. The testing component 51 and the driving component 52 are arranged along the direction close to the conveying mechanism 2. The testing component 51 includes a testing frame 511, a movable swing frame 512 disposed within the testing frame 511, a spring piece 513 disposed between the testing frame 511 and the swing frame 512, and a sensing module 514 disposed on the side of the swing frame 512. The direction of movement of the swing frame 512 is perpendicular to the arrangement direction of the testing component 51 and the driving component 52. The drive assembly 52 includes an upright drive plate 521, a rotatable drive wheel 522 mounted on the drive plate 521, a ninth drive member 523 for driving the drive wheel 522 to rotate, three rotatable driven wheels 524 mounted on the drive plate 521, and a drive belt 525 connected to the drive wheel 522 and the three driven wheels 524. The ninth drive member 523 is a motor, the sensing module 514 is a laser sensor, the length direction of the drive plate 521 is the same as the swing direction of the swing frame 512, and the upper part of the drive belt 525 has a drive section extending along the length direction of the drive plate 521.

[0049] During testing, the rotating workpiece 100 is placed on the swing frame 512 along its axial direction, with the end of the rotating workpiece 100 pressing against the drive section. Then, the ninth drive unit 523 drives the drive wheel 522 to rotate, which in turn drives the driven wheel 524 and the drive belt 525 to move. The drive section causes the rotating workpiece 100 pressing against it to rotate. During the rotation of the rotating workpiece 100, the swing frame 512 can support the bottom of the rotating workpiece 100 and swing along with the rotation of the rotating workpiece 100. The sensing module 514 can detect the swing amplitude of the swing frame 512, thereby measuring the imbalance of the rotating workpiece 100 with high testing accuracy.

[0050] In this embodiment, the test frame 511 includes two opposing first frames 5111, which are arranged along the direction close to the drive assembly 52. ​​The sensing module 514 is disposed on the side of one of the first frames 5111 close to the drive assembly 52. ​​The swing frame 512 includes two opposing second frames 5121 and a support plate 5122 connected to the two second frames 5121 at both ends. A support block 5123 is disposed on the support plate 5122, and a first support groove 5124 is formed on the support block 5123. The first support groove 5124 extends along the direction from the test assembly 51 to the drive assembly 52. ​​The rotating workpiece 100 is placed in the first support groove 5124. The two second frames 5121 are movably accommodated in the two first frames 5111. A spring piece 513 is disposed between the two sides of each second frame 5121 and the first frame 5111 to allow the second frame 5121 to swing left and right.

[0051] A clamping assembly 53 is also provided between the two second frames 5121. The clamping assembly 53 includes two clamping plates 531 that can be opened or closed relative to each other, and a first driving member 532 for driving the movement of the two clamping plates 531. The first driving member 532 is a pneumatic finger located below the support plate 5122. The two clamping plates 531 are respectively located on the two driving ends of the pneumatic finger. The movement direction of the two clamping plates 531 is perpendicular to the arrangement direction of the two second frames 5121.

[0052] In this embodiment, the rotating workpiece 100 includes a rotating body and a shell. The shell is coaxially mounted on the rotating body and rotatably connected to it. When the two clamping plates 531 are closed relative to each other, the shell is supported in the first bearing groove 5124, and the upper ends of the two clamping plates 531 press against the shell. The drive assembly 52 drives the rotating body to rotate, forming a first gap 533 between the two clamping plates 531. The bearing plate 5122 is movably accommodated in the first gap 533. In this way, when the two clamping plates 531 are closed relative to each other, they can clamp the shell of the rotating workpiece 100 without affecting the movement of the bearing plate 5122, thereby further improving the testing accuracy of dynamic balance.

[0053] In this embodiment, combined with Figure 3 As shown, the weight-removing mechanism 6 includes a bearing assembly 61, a weight-removing assembly 62, and a dust-collecting assembly 63. The bearing assembly 61 is used to place the rotating workpiece 100. The weight-removing assembly 62 includes a sliding seat 625 movably disposed along the direction close to or away from the bearing assembly 61, a second driving member 622 for driving the sliding seat 625 to move, a spindle seat 621 disposed on the sliding seat 625, a drill bit 623 rotatable about its own axis and disposed in the spindle seat 621, and a third driving member 624 for driving the drill bit 623 to rotate. The axial direction of the drill bit 623 is the same as the direction of movement of the spindle seat 621. Among them, the second driving member 622 is a motor lead screw structure, the third driving member 624 is a motor belt structure, and the drill bit 623 is a tungsten carbide end mill for drilling, with a gear at its rear end that is driven and meshes with the motor belt structure.

[0054] The dust collection assembly 63 includes a slide plate 634 movably mounted on a sliding seat 625 along the axial direction of the drill bit 623, and a dust collection pipe 631 mounted on the slide plate 634. The rear end of the dust collection pipe 631 is connected to an external exhaust fan. The dust collection pipe 631 extends in a direction perpendicular to the axial direction of the drill bit 623. One end of the dust collection pipe 631 near the spindle seat 621 has a dust collection part. The two opposite sides of the dust collection part are respectively provided with a dust collection port 632 and a sliding hole 633. The dust collection port 632 is positioned facing the support assembly 61, and the sliding hole 633 is positioned facing the drill bit 623. The drill bit 623 is slidably inserted into the sliding hole 633 along its axial direction. A second stop 635 is provided on the side of the slide plate 634. A guide rod 636 is provided on the second stop 635. An elastic element 637, which is a spring, is sleeved on the guide rod 636. The slide plate 634 is slidably sleeved on the guide rod 636. The two ends of the spring are connected to the slide plate 634 and the second stop 635 respectively.

[0055] During the weight removal process, the sliding seat 625 drives the spindle seat 621 and the dust collection component 63 to approach the bearing component 61. Then, the dust collection pipe 631 comes into contact with the rotating workpiece 100. The sliding seat 625 continues to move, and the dust collection pipe 631 slides backward and compresses the spring under the squeezing action of the rotating workpiece 100. At this time, the drill bit 623 gradually passes through the dust collection port 632 and comes into contact with the rotating workpiece 100. Then, the drill bit 623 rotates and drills holes in the rotating workpiece 100 to remove weight. At this time, the dust collection port 632 can come into contact with the rotating workpiece 100 and suck out the generated debris, preventing debris from flying and causing damage to the physical and mental health of workers.

[0056] In this embodiment, the supporting assembly 61 includes a supporting base 611, a second supporting groove 615 formed on the supporting base 611, an adjusting base 612 movably disposed along a direction close to or away from the supporting base 611, a fourth driving member 613 for driving the adjusting base 612 to move, and an adjusting block 614 disposed at the end of the adjusting base 612 away from the supporting base 611. The second supporting groove 615 is used to support the rotating workpiece 100. The adjusting base 612 is located at the end of the second supporting groove 615 and its moving direction is the same as the length direction of the second supporting groove 615. The fourth driving member 613 is a cylinder. When the conveying mechanism 2 places the rotating workpiece 100 into the second supporting groove 615, the adjusting block 614 can push the rotating workpiece 100 during the movement of the adjusting base 612, thereby adjusting the axial loading position of the rotating workpiece 100 and preventing excessive weight-reduction errors due to loading deviations of the rotating workpiece 100.

[0057] In this embodiment, the weight-removing mechanism 6 located at the first weight-removing station is used to drill holes to remove weight from the end of the rotating workpiece 100. On the weight-removing mechanism 6, the weight-removing component 62 and the adjusting seat 612 are arranged opposite to each other, and the axial direction of the drill bit 623 is the same as the length direction of the second bearing groove 615. The weight-removing mechanism 6 located at the second weight-removing station is used to remove weight from the side of the rotating workpiece 100. On the weight-removing mechanism 6, the weight-removing component 62 and the adjusting seat 612 are arranged adjacent to each other, and the axial direction of the drill bit 623 is set at an angle to the length direction of the second bearing groove 615. The specific angle can be flexibly set according to the drilling position.

[0058] In this embodiment, the weight-removing mechanism 6 further includes a clamping assembly 64, which is located on one side of the second bearing groove 615 in the width direction. The clamping assembly 64 includes a clamping seat 641 movably disposed along a direction close to or away from the bearing assembly 61, a fifth driving member 642 for driving the clamping seat 641 to move, a clamping rod 643 rotatably disposed on the clamping seat 641, and a sixth driving member 644 for driving the clamping rod 643 to rotate. The rotation direction of the clamping rod 643 is perpendicular to the movement direction of the clamping seat 641. Both the fifth driving member 642 and the sixth driving member 644 are cylinders. The end of the clamping rod 643 close to the bearing assembly 61 is the clamping end, and the end away from the bearing assembly 61 is the driving end. The driving end is hinged to the output end of the sixth driving member 644. The clamping end is used to clamp onto the rotating workpiece 100 to prevent the rotating workpiece 100 from shifting during the weight removal process, effectively improving the weight removal accuracy.

[0059] In this embodiment, the weight-removing mechanism 6 further includes a corner assembly 65, which is located at the end of the second bearing groove 615 away from the conveying mechanism 2 along its length. The corner assembly 65 includes a corner seat 651, a first gripper module 652 rotatable about its own axis and mounted on the corner seat 651, and a seventh drive member 653 for driving the first gripper module 652 to rotate. The axis of the first gripper module 652 coincides with the length direction of the second bearing groove 615. The seventh drive member 653 is a motor, and a gear is provided at the end of the first gripper module 652, with the motor and gear being connected in a transmission.

An air inlet channel communicating with the air inlet of the first gripper module 652 is also provided inside the shaft cylinder 655. The inlet of the air inlet channel is connected to an air inlet pipe through a rotary joint, and the air inlet pipe is connected to an external air source. The first gripper module 652 can clamp the rotating workpiece 100 and drive the rotating workpiece 100 to rotate during the weight removal process, so as to drill holes at different positions of the rotating workpiece 100.

[0061] In this embodiment, combined with Figure 1 As shown, the loading and unloading stations are located in the middle of the conveying direction of the conveying mechanism 4, and the defective station is arranged at the end of the conveying direction of the conveying mechanism 4. The conveying mechanism 4 includes two chain conveyors 43 arranged side by side and operating synchronously. There is a third gap 44 between the two chain conveyors 43.

[0062] The first top-feeding assembly 41 includes a liftable first top-feeding frame 411 and an eighth drive member 412 for driving the first top-feeding frame 411 to rise and fall. The eighth drive member 412 is a cylinder. The first top-feeding frame 411 is used to lift and collect defective products during its lifting and falling process. The second top-feeding assembly 45 includes a liftable second top-feeding frame 451 and a tenth drive member 452 for driving the second top-feeding frame 451 to rise and fall. The tenth drive member 452 is a cylinder. The first top-feeding frame 411 is used to lift the rotating workpiece 100 upward during loading to facilitate the handling by the conveying mechanism 2, or to receive the rotating workpiece 100 during unloading and drive the rotating workpiece 100 downward onto the conveying mechanism 4.

[0063] Combination Figure 4 As shown, a collecting component 42 is disposed above the first top-feeding component 41. The collecting component 42 includes a collecting seat 421, a first conveyor belt module 422 disposed on the collecting seat 421, and a guiding module 423. The first conveyor belt module 422 is a belt conveyor, and the conveying direction of the first conveyor belt module 422 is the same as the conveying direction of the conveying component. The front end of the first conveyor belt module 422 is located directly above the first top-feeding component 41. Multiple first stops 424 are spaced apart on the belt of the first conveyor belt module 422 along its conveying direction. The guiding module 423 includes two blocks hinged to the front end of the first conveyor belt module 422. The guide plate 4231 has a limit plate 4232 below it. The extension direction of the rotation axis of the guide plate 4231 is perpendicular to the conveying direction of the first conveyor belt module 422. The limit plate 4232 can abut against the bottom of the guide plate 4231 to prevent the guide plate 4231 from rotating downward. Multiple first blocks 424 can pass between two guide plates 4231 in sequence, forming a second gap 4233 between the two guide plates 4231. The first top material rack 411 can be lifted and passed through the second gap 4233. The length of the rotating workpiece 100 is greater than the second gap 4233.

[0064] After a defective product is detected at the retesting station, the first top material rack 411 lifts the defective product upwards. During the upward movement, the defective product pushes the two guide plates 4231 to rotate upwards. When the defective product rises to the position where it is detached from the guide plates 4231, the two guide plates 4231 rotate downwards under the action of gravity and come into contact with the limiting plate 4232. At this time, the guide plates 4231 tilt downwards along the direction close to the first conveyor belt module 422. Then, the first top material rack 411 drives the defective product to descend. As the defective product descends, it is supported by the two guide plates 4231. The first top material rack 411 continues to descend and passes through the second gap 4233. The defective product rolls along the length of the guide plates 4231 to the first stop 424. Then, the first stop 424 carries the defective product forward, thereby completing the collection of defective products without the need for manual removal, effectively improving the collection efficiency of defective products.

[0065] A second conveyor module 425 is also provided to the side of the first conveyor module 422. The second conveyor module 425 is also a belt conveyor, which moves parallel to and synchronously with the first conveyor module 422. When defective products are conveyed on the first conveyor module 422, their ends can be supported on the second conveyor module 425 to prevent the defective products from deflecting and falling off during the conveying process.

[0066] The implementation principle of the dynamic balancing test weight removal device in this application embodiment is as follows:

[0067] The conveying mechanism 4 continuously conveys the rotating workpiece 100 forward, and the handling mechanism 2 sequentially transports the rotating workpiece 100 to the initial testing station, the first de-weighting station, the second de-weighting station, and the retesting station. With the cooperation of the two testing mechanisms 5 and the two de-weighting mechanisms 6, the rotating workpiece 100 completes two tests and two de-weightings respectively. Then, the handling mechanism 2 sends the rotating workpiece 100 back to the conveying mechanism 4. If the rotating workpiece 100 is found to be defective, the first ejector assembly 41 lifts the defective product onto the collection assembly 42.

[0068] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
