Technical Field

[0001] This invention belongs to the field of sealing ring assembly technology, and relates to a multi-station fully automatic sealing ring fitting device. Background Technology

[0002] Sealing rings, used to improve the airtightness and waterproof performance of products, are widely used in various industries. Currently, the assembly of sealing rings is mostly done manually. However, manual assembly of sealing rings is inefficient.

[0003] When multiple sealing rings need to be assembled on a workpiece or when the workpiece is small, the assembly difficulty increases significantly when workers wear cleanroom gloves, making the operation extremely inconvenient and seriously affecting production efficiency.

[0004] Therefore, designing a fully automatic sealing ring fitting device has become an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-station fully automatic sealing ring fitting device for the automatic sorting, loading, assembly, and unloading of workpieces and sealing rings, thereby improving production efficiency through a fully automated process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-station fully automatic sealing ring fitting device includes: The transport mechanism is used to carry workpieces and transport them sequentially through different workstations. A workpiece loading mechanism is used to sort workpieces and pick them up to a transport mechanism. A sealing ring fitting mechanism is used to sort sealing rings and fit them onto the workpieces of the transport mechanism. A workpiece unloading mechanism is used to grab the workpiece after the sealing ring is fitted on the transport mechanism and automatically unload it. The workpiece loading mechanism, the sealing ring fitting mechanism, and the workpiece unloading mechanism correspond to the loading station, the assembly station, and the unloading station, respectively.

[0008] Furthermore, the self-clamping device includes: a fixing block, a self-tightening slider, a connecting rod, and an unlocking push rod; The fixing block is fixed to the top of the equal-dividing plate. The top of the fixing block is provided with a sliding groove. The self-tightening slider is slidably installed in the sliding groove. A self-tightening spring is provided between the self-tightening slider and the side wall of the sliding groove. The self-tightening spring is used to apply a preload to the self-tightening slider. A lever extends from the side wall of the self-tightening slider, and the lever extends beyond the fixed block; The unlocking push rod is slidably mounted on the bottom end of the equal-division plate, and a return spring is provided on the outer sleeve of the unlocking push rod; The side of the fixed block is provided with a hinged connecting rod, and the two ends of the connecting rod abut against the lever and the unlocking push rod, respectively. The self-tightening spring and the reset spring have opposite preset elastic force directions. After the unlocking push rod is compressed by external force, it drives the self-tightening slider to compress the self-tightening spring through the connecting rod.

[0009] Furthermore, the unlocking device is an unlocking cylinder, and the unlocking cylinder corresponds to the position of the unlocking push rod.

[0010] Furthermore, the workpiece feeding mechanism includes: A workpiece feeding tray, used for sorting workpieces and selecting workpiece orientation; The workpiece direct vibration channel is connected to the outlet of the workpiece feeding tray and is used to feed the workpieces in sequence and with limited positioning. The workpiece distribution seat is located at the outlet of the workpiece direct vibration channel. The top of the workpiece distribution seat is provided with a workpiece distribution groove that can only accommodate one workpiece. The workpiece distribution seat is driven by a workpiece distribution cylinder to perform horizontal displacement for distributing the workpiece. The top of the workpiece distribution seat is provided with a workpiece distribution sensor, which faces the distribution groove. A workpiece loading gripper, which is driven by a loading cylinder to grip the workpiece; The workpiece loading motion platform is used to drive the loading chuck to perform planar displacement and lifting movements; The workpiece passes sequentially through the workpiece feeding tray and the workpiece direct vibration channel to the material distribution groove of the workpiece distribution seat. The loading claw grabs the workpiece under the drive of the loading motion platform and the loading cylinder and transfers it to the transportation mechanism to complete the loading.

[0011] Furthermore, the sealing ring fitting mechanism includes a sealing ring feeding mechanism for sorting sealing rings, a sealing ring dispensing mechanism for dispensing materials, a sealing ring picking mechanism for transferring and fitting sealing rings, and a sealing ring motion platform for driving the displacement of the sealing ring picking mechanism. The sealing ring picking mechanism includes a sealing ring picking claw, a sealing ring picking claw cylinder, a sealing ring ejection slider, and a sealing ring ejection cylinder. The sealing ring picking claw cylinder drives the sealing ring picking claw to expand, and the sealing ring picking claw grips the sealing ring through its inner circle. The sealing ring ejection cylinder drives the sealing ring ejection slider to reciprocate along the ejection claw, and the sealing ring ejection slider interferes with the sealing ring to disengage it from the sealing ring picking claw.

[0012] Furthermore, the sealing ring dispensing mechanism includes: a dispensing chute, a dispensing push rod, a sealing ring dispensing cylinder, a sealing ring limiting part, and a sealing ring dispensing sensor; The side of the material distribution chute is provided with a through hole for the sealing ring to pass through, and the through hole is connected to the sealing ring feeding mechanism; The material distribution push rod is located in the material distribution groove, and the sealing ring material distribution cylinder is used to drive the material distribution push rod to reciprocate within the material distribution groove; The material distribution chute is provided with a sealing ring limiting part at one end opposite to the material distribution push rod. The sealing ring limiting part is used for positioning the sealing ring.

[0013] Furthermore, the sealing ring limiting part includes limiting sliders. The three limiting sliders and the material distribution push rod cooperate to limit the planar degree of freedom of the sealing ring. The limiting sliders are driven by a power chuck disk.

[0014] Furthermore, the number of sealing ring fitting mechanisms is two or more, and different sealing ring fitting mechanisms perform sealing ring assembly processes at different positions on the workpiece.

[0015] Furthermore, the workpiece unloading mechanism includes an unloading motion platform, unloading jaws, and a workpiece collecting slide; The unloading claw is driven by the unloading cylinder to grip the workpiece after the sealing ring is fitted; The unloading motion platform is used to drive the unloading chuck to move horizontally and vertically. The workpiece collection slide is used to transfer workpieces to an external collection point; The unloading claw, driven by the unloading cylinder and the unloading motion platform, is used to grab the workpiece with the sealing ring on it on the transport mechanism and transfer it to the collection slide.

It automatically sorts and distributes workpieces and sealing rings, with multiple workstations and a high degree of automation, which helps to improve production efficiency; 2. By fixing the workpiece with a self-clamping device, the workpiece fixing effect is improved without obstructing the sealing ring application process, ensuring the sealing ring application accuracy and process repeatability, and reducing the cost of subsequent equipment downtime and debugging. 3.

[0024] Reference Appendix Figure 1-2 As shown, a multi-station fully automatic sealing ring fitting device includes: The transport mechanism 100 is used to carry the workpieces and transport them sequentially through different workstations. The workpiece loading mechanism 200 is used to sort workpieces and grab them to the transport mechanism 100. A sealing ring fitting mechanism 300 is used to sort sealing rings and fit them onto the workpieces of the transport mechanism 100. The workpiece unloading mechanism 400 is used to grab the workpiece with the sealing ring on the transport mechanism 100 and unload it automatically. The workpiece loading mechanism 200, the sealing ring fitting mechanism 300, and the workpiece unloading mechanism 400 correspond to the loading station, the assembly station, and the unloading station, respectively.

[0025] The transport mechanism 100 moves intermittently and its trajectory is a closed loop. That is, the transport mechanism 100 passes under the workpiece loading mechanism 200, the sealing ring fitting mechanism 300 and the workpiece unloading mechanism 400 in sequence, corresponding to the loading, assembly and unloading of the workpiece, and cycles through them.

[0026] In terms of control, the transfer of workpieces between different workstations needs to be coordinated. Therefore, in order to simplify control, the actions of loading, assembling and unloading are adapted to the indirect movement of the transport mechanism 100.

[0027] The transportation unit 100 can be a circulating assembly line or a divided tray.

[0028] Initially, the transport mechanism 100 is located in the loading area corresponding to the workpiece loading mechanism 200. The workpiece loading mechanism 200 transfers the workpiece to the transport mechanism 100. The transport mechanism 100 carries the workpiece to the assembly area corresponding to the sealing ring fitting mechanism 300. The sealing ring fitting mechanism 300 grabs the sealing ring and fits it onto the designated position of the workpiece to complete the assembly. Finally, the transport mechanism 100 carries the workpiece with the sealing ring fitted to the unloading area corresponding to the workpiece unloading mechanism 400. The workpiece unloading mechanism 400 removes the workpiece from the transport mechanism 100 to complete the unloading. The transport mechanism 100 then returns to the loading area corresponding to the workpiece loading mechanism 200 to prepare for loading. Repeating the above steps constitutes the fully automated process of loading, assembly, and unloading of the device.

[0029] Reference Appendix Figure 3-4 As shown in this embodiment, the transport mechanism 100 is a dividing plate, on which multiple self-clamping devices 110 are provided. These self-clamping devices 110 are used to fix the workpiece. Unlocking devices are provided at the loading and unloading stations to loosen the self-clamping devices 110. The workpiece loading mechanism 200, the sealing ring fitting mechanism 300, and the workpiece unloading mechanism 400 are fixed around the dividing plate. The number of self-clamping devices 110 on the dividing plate corresponds to the number of stations, meaning that each station can operate with each rotation of the dividing plate, thus improving production efficiency and reducing standby time and intervals. A single rotation of the workpiece fixed by the self-clamping devices 110 on the dividing plate completes the process cycle.

[0030] The interval between the rotation of the equalizing disc is determined by the working time of different workstations. In other words, the rotation of the equalizing disc completes the signal control for the start time of the feeding, assembly and unloading processes.

[0031] In this embodiment, the self-clamping device 110 includes: a fixing block 111, a self-tightening slider 112, a connecting rod 115, and an unlocking push rod 116; The fixing block 111 is fixed to the top of the equal division plate. The top of the fixing block 111 is provided with a sliding groove. The self-tightening slider 112 is slidably installed in the sliding groove. A self-tightening spring 113 is provided between the self-tightening slider 112 and the side wall of the sliding groove. The self-tightening spring 113 is used to apply a preload to the self-tightening slider 112. A lever 114 extends from the side wall of the self-tightening slider 112, and the lever 114 extends to the outside of the fixing block 111; The unlocking push rod 116 is slidably mounted on the bottom end of the equal-division plate, and a return spring is provided on the outer sleeve of the unlocking push rod 116; The side of the fixed block 111 is provided with a connecting rod 115, and the two ends of the connecting rod 115 abut against the lever 114 and the unlocking push rod 116 respectively. The self-tightening spring 113 and the reset spring have opposite preset elastic force directions. After the unlocking push rod 116 is compressed by external force, it drives the self-tightening slider 112 to compress the self-tightening spring 113 through the connecting rod 115.

[0032] During loading, the unlocking device presses the unlocking push rod 116. After being compressed by external force, the unlocking push rod 116 drives the self-tightening slider 112 to compress the self-tightening spring 113 through the connecting rod 115. That is, the workpiece loading mechanism 200 puts the gripped workpiece into the slide groove. Then the unlocking device resets, and the unlocking push rod 116 and the self-tightening slider 112 reset under the elastic force of the reset spring and the self-tightening spring 113, respectively. The self-tightening slider 112 presses the workpiece under the preload of the self-tightening spring 113, so as to achieve the effect of clamping and fixing the workpiece.

[0033] During the unloading process, the workpiece unloading mechanism 400 grabs the workpiece, and then activates the unlocking device to squeeze the unlocking push rod 116. After the unlocking push rod 116 is compressed by external force, it drives the self-tightening slider 112 to compress the self-tightening spring 113 through the connecting rod 115, and the workpiece can then be taken out by the workpiece unloading mechanism 400.

[0034] In this embodiment, the head of the self-tightening slider 112 is V-shaped. Compared to a flat head, the V-shaped head has a guiding function. Combined with the preload of the self-tightening spring 113, it achieves the effect of positioning the workpiece and restricting its degrees of freedom. This method of fixing the workpiece greatly ensures the accuracy of the workpiece's transfer and positioning, providing a high-precision foundation for the subsequent sealing ring fitting mechanism 300 to align the sealing ring with the workpiece, especially in scenarios where the workpiece volume and the sealing ring hole diameter are small.

[0035] Reference Appendix Figure 12-13 As shown in this embodiment, the unlocking device is an unlocking cylinder 120, which corresponds to the unlocking push rod 116. The extension and retraction of the cylinder continuously applies pressure to the unlocking push rod 116. When the cylinder is activated, its extension portion presses against the unlocking push rod 116, causing the self-clamping device 110 to relax. When the cylinder resets, the self-clamping device 110 is in a self-tightened state due to the elastic force of the return spring and the self-tightening spring 113.

[0036] Reference Appendix Figure 5 As shown, in this embodiment, the workpiece loading mechanism 200 includes: A workpiece feeding tray, used for sorting workpieces and selecting workpiece orientation; The workpiece direct vibration channel 210 is connected to the outlet of the workpiece feeding tray. The workpiece direct vibration channel 210 is used to feed the workpieces in sequence and with limited positioning. The workpiece distribution seat 220 is located at the outlet of the workpiece direct vibration channel 210. The top of the workpiece distribution seat 220 is provided with a workpiece distribution groove that can only accommodate one workpiece. The workpiece distribution seat 220 is driven by a workpiece distribution cylinder to perform horizontal displacement for distributing workpieces. The top of the workpiece distribution seat 220 is provided with a workpiece distribution sensor, which faces the distribution groove. The workpiece loading gripper 230 is driven by a loading cylinder to grip the workpiece. The workpiece loading motion platform 240 is used to drive the loading chuck to perform planar displacement and lifting motion. The workpiece passes sequentially through the workpiece feeding tray and the workpiece direct vibration channel 210 to the material distribution groove of the workpiece distribution seat 220. The loading claw grabs the workpiece under the drive of the loading motion platform and the loading cylinder and transfers it to the transport mechanism 100 to complete the loading.

[0037] The workpiece feeding tray works in conjunction with the workpiece direct vibration channel 210 to perform directional screening and sorting of multiple workpieces, thereby enabling the one-to-one feeding of workpieces.

[0038] To facilitate the gripping of workpieces by the chuck 230 and to prevent jamming between workpieces, the workpiece distributor 220 distributes the workpieces one by one.

[0039] The workpiece passes sequentially through the workpiece feeding tray and the workpiece direct vibration channel 210 to reach the workpiece distribution groove of the workpiece distribution seat 220. The distribution sensor is triggered, and the workpiece distribution cylinder drives the workpiece distribution seat 220 to shift and misalign with the direct vibration channel to complete the distribution.

[0040] Driven by the workpiece loading motion platform 240, the workpiece loading jaw 230 moves to above the workpiece distribution groove. The loading cylinder drives the workpiece loading jaw 230 to grab the workpiece. Then, the workpiece loading motion platform 240 drives the workpiece loading jaw 230 to carry the workpiece to above the self-clamping device 110 of the equalizing plate. After the unlocking device of the loading station is activated to make the self-clamping device 110 loose, the workpiece loading motion platform 240 drives the workpiece loading jaw 230 to insert the workpiece into the slide groove of the self-clamping device 110. Then, the unlocking device is reset, the workpiece is clamped by the self-tightening slider 112, and finally the workpiece loading jaw 230 is released to execute the next cycle.

[0041] The error when the workpiece loading motion platform 240 drives the workpiece loading jaws 230 to place the workpiece will be eliminated by the squeezing and guiding action of the self-tightening slider 112 of the V-shaped head, ensuring the accuracy requirements of subsequent processes.

[0042] In this implementation example, the workpiece loading motion platform 240 can be an XYZ three-axis motion platform or an XZ two-axis motion platform.

[0043] Reference Appendix Figure 6-8 As shown, in this embodiment, the sealing ring fitting mechanism 300 includes a sealing ring feeding mechanism 310 for sorting sealing rings, a sealing ring dispensing mechanism 320 for dispensing materials, a sealing ring picking mechanism 330 for transferring and fitting sealing rings, and a sealing ring motion platform 340 for driving the sealing ring picking mechanism 330 to move. In fact, the sealing ring picking mechanism 330 includes a sealing ring picking claw 331, a sealing ring picking claw cylinder 332, a sealing ring ejection slider 333, and a sealing ring ejection cylinder 334. The sealing ring picking claw cylinder 332 is used to drive the sealing ring picking claw 331 to expand. The sealing ring picking claw 331 is used to grip the sealing ring through its inner circle. The sealing ring ejection cylinder 334 is used to drive the sealing ring ejection slider 333 to reciprocate along the ejection claw. The sealing ring ejection slider 333 is used to interfere with the sealing ring to disengage the sealing ring from the sealing ring picking claw 331. The sealing ring is opened from the inner ring by the sealing ring picking claw 331. Under the elasticity of the sealing ring, the sealing ring is fixed on the sealing ring picking claw 331. There is a cavity between the multiple sealing ring picking claws 331 to accommodate the workpiece. The sealing ring moving platform 340 drives the sealing ring picking claws 331 to carry the sealing ring to the periphery of the workpiece. The workpiece is located in the cavity between the multiple sealing ring picking claws 331. When it reaches the designated position, the sealing ring is pushed by the sealing ring unloading slider 333, so that the sealing ring is detached from the sealing ring picking claw 331 and put on the workpiece. This achieves the effect of automatically grabbing and putting on the sealing ring, eliminating the dependence on manual labor and improving production efficiency.

[0044] In this embodiment, the cross-section of the sealing ring picking claw 331 is arc-shaped, and multiple sealing ring picking claws 331 are arranged in a circular pattern, with cavities between them for accommodating the workpiece. The circularly arranged arc-shaped sealing ring picking claws 331 can evenly spread and fix the sealing ring, preventing it from flying off due to uneven force when gripping it.

[0045] In this embodiment, the sealing ring picking mechanism 330 is mounted above the sealing ring dispensing mechanism 320 via the sealing ring moving platform 340; The sealing ring motion platform 340 includes a horizontal linear module and a vertical lifting module. The horizontal linear module drives the sealing ring picking mechanism 330 to move horizontally, and the vertical lifting module drives the sealing ring picking mechanism 330 to perform lifting and reciprocating motion. The horizontal linear module drives the sealing ring picking claw 331 to move back and forth between the workpiece and the sealing ring dispensing mechanism 320. In addition to driving the sealing ring picking claw 331 to move up and down to pick up the material, the vertical lifting module also controls the installation position of the sealing ring relative to the workpiece. Different installation positions correspond to different installation heights, that is, different heights of the sealing ring picking claw 331 relative to the workpiece. According to the preset data, the vertical lifting module drives the sealing ring picking claw 331 to carry the sealing ring to the designated position, that is, the lower edge of the sealing ring picking claw 331 is flush with the upper edge of the sealing ring mounting groove on the workpiece. Under the push of the sealing ring unloading slider 333, the sealing ring disengages from the sealing ring picking claw 331 and is fitted into the sealing ring mounting groove on the workpiece.

[0046] In this embodiment, the sealing ring feeding mechanism 310 includes a vibratory feeder and a direct vibration channel. The two ends of the direct vibration channel are connected to the vibratory feeder and the sealing ring sorting mechanism 320, respectively. The vibratory feeder sorts the sealing rings, and the direct vibration channel feeds the sealing rings sequentially.

[0047] Reference Appendix Figure 9-11 As shown in this embodiment, the components include a material distribution chute, a material distribution push rod 321, a sealing ring material distribution cylinder 322, a sealing ring limiting part, and a sealing ring material distribution sensor. The side of the material distribution chute is provided with a through hole 323 for the sealing ring to pass through, and the through hole 323 is connected to the sealing ring feeding mechanism 310. The material distribution push rod 321 is located in the material distribution groove, and the sealing ring material distribution cylinder 322 is used to drive the material distribution push rod 321 to reciprocate in the material distribution groove. The end of the material distribution chute opposite to the material distribution push rod 321 is provided with a sealing ring limiting part, which is used for positioning the sealing ring; The sealing ring distribution sensor faces the sealing ring limiting part and is used to monitor whether there is a sealing ring at the sealing ring limiting part. The sealing ring of the direct vibration channel enters the distribution chute through the through hole 323. The sealing ring distribution cylinder 322 drives the distribution push rod 321 to extend and push the sealing ring to the sealing ring limiting part. At the same time, the rod of the distribution push rod 321 blocks the through hole 323. After the distribution push rod 321 resets, the next sealing ring enters the distribution chute through the through hole 323. This process is repeated to complete the distribution action.

[0048] In this embodiment, the head of the material dispensing push rod 321 is V-shaped. The V-shape helps in positioning the sealing ring, ensuring the gripping accuracy of the sealing ring picking mechanism 330. Furthermore, when the material dispensing push rod 321 extends, if the sealing ring has not yet fully passed through the through hole 323 into the material dispensing groove, the V-shaped slope provides guidance, prompting the sealing ring to quickly enter the groove. Compared to a flat-headed material dispensing push rod 321, this greatly reduces the risk of the sealing ring getting stuck.

[0049] In this embodiment, the sealing ring limiting part includes limiting sliders 324. Three limiting sliders 324 and a material distribution push rod 321 cooperate to restrict the planar degrees of freedom of the sealing ring. The limiting sliders 324 are driven by a power jaw disc 325. To ensure that the sealing ring picking claw 331 of the sealing ring picking mechanism 330 can smoothly pick up the sealing ring, the positioning accuracy of the sealing ring is extremely important. Therefore, three limiting sliders 324 and a material distribution push rod 321 are needed to cooperate to restrict the degrees of freedom of the sealing ring in four directions: front, back, left, and right. Simultaneously, to ensure that the sealing ring picking claw 331 can open smoothly and pick up the sealing ring, the three limiting sliders 324 need to be moved away by the power jaw disc when the sealing ring picking claw 331 is working.

[0050] The operation sequence is as follows: the sealing ring is driven to the sealing ring limiting part by the material distribution push rod 321. The sealing ring is positioned by the three limiting sliders 324. Under the drive of the sealing ring movement platform 340, the sealing ring picking claw 331 moves downward and is located on the inner ring of the sealing ring, completing the gripping and positioning. Then, the limiting sliders 324 are opened away from the sealing ring by the power claw disc to avoid interfering with the movement of the sealing ring picking claw 331. Finally, the sealing ring picking claw 331 is opened by the sealing ring picking claw cylinder 332 to complete the gripping of the sealing ring.

[0051] In this embodiment, the limiting slider 324 has a semi-circular groove on the side opposite to the material distributing push rod 321. The semi-circular groove facilitates the positioning of the sealing ring and helps improve positioning accuracy.

[0052] Reference Appendix Figure 13 As shown in this embodiment, the number of sealing ring fitting mechanisms 300 is two or more, and different sealing ring fitting mechanisms 300 perform sealing ring assembly processes at different positions on the workpiece. In the sealing ring fitting mechanism 300, when performing the sealing ring fitting assembly step, the assembly position of the sealing ring corresponds to the movement distance of the vertical lifting module.

[0053] When a workpiece requires the assembly of multiple sealing rings 500, the assembly height of different sealing rings is different. That is, when debugging different sealing ring mounting mechanisms 300, in addition to the change in the horizontal coordinate of the sealing ring picking claw 331, the stroke of the vertical lifting module when mounting the sealing ring needs to be set in advance. This corresponds to the different heights of the sealing ring picking claw 331 relative to the workpiece. According to the pre-set data, the vertical lifting module drives the sealing ring picking claw 331 to carry the sealing ring to the designated position, and the lower edge of the sealing ring picking claw 331 is flush with the upper edge of the sealing ring mounting groove on the workpiece. Under the push of the sealing ring ejection slider 333, the sealing ring 500 is disengaged from the sealing ring picking claw 331 and mounted in the sealing ring mounting groove on the workpiece.

[0054] Different sealing ring fitting mechanisms 300 are used to fit sealing rings of different heights, with the process sequence from bottom to top. This greatly improves production efficiency and reduces the cost of later debugging.

[0055] Reference Appendix Figure 12 As shown, in this embodiment, the workpiece unloading mechanism 400 includes an unloading motion platform 410, an unloading claw 420, and a workpiece collecting slide 430; The unloading claw 420 is driven by the unloading cylinder to grip the workpiece after the sealing ring is fitted; The unloading motion platform 410 is used to drive the unloading claw 420 to move horizontally and lift vertically. The workpiece collection slide 430 is used to transfer workpieces to an external collection point; The unloading claw 420, driven by the unloading cylinder and the unloading motion platform 410, is used to grab the workpiece with the sealing ring on the transport mechanism 100 and transfer it to the collection slide.

[0056] During unloading, the equalizing disc rotates, transferring the workpiece with the sealing ring to below the workpiece unloading mechanism 400. Driven by the unloading cylinder and the unloading motion platform 410, the unloading claw 420 grabs the workpiece. Then, the unlocking device is activated to relax the self-clamping device 110. After the unloading motion platform 410 drives the unloading claw 420 to remove the workpiece, the unlocking device is reset. The unloading motion platform 410 drives the workpiece to above the workpiece collecting slide 430, and the unloading claw 420 releases the workpiece, allowing it to fall into the collecting slide to complete the unloading and collection.
