Description

Technical Field

[0001] This invention relates to the field of bicycle parts processing technology, and in particular to a method and apparatus for processing quick-release hubs. Background Technology

[0002] The quick-release hub is a core component in bicycle hub assembly, mainly composed of the quick-release hub body and the quick-release hub protective cover. It is widely used in the rapid disassembly and assembly of bicycle wheelsets. It is characterized by its compact structure, high assembly precision requirements, and large mass production demand. Its assembly quality directly affects the stability and service life of the wheelset during disassembly and assembly.

[0003] In the existing technology, the conventional quick-release head processing method for hubs relies on rotary processing equipment to complete the cyclic operation. Two sets of vibrating feeding mechanisms realize the automatic sorting and conveying of the quick-release head protective cover and quick-release head body respectively. Defective workpieces are identified by weight detection at the workstation. In conjunction with the multi-station rotary table, continuous processes such as parts feeding, mechanical pressing and positioning, workpiece pressing and assembly, and finished product unloading are completed in sequence. The mechanical limit structure corrects the placement posture of the parts, thereby completing the standardized batch processing operation of hub quick-release heads.

[0004] Regarding the aforementioned technologies, in the traditional hub quick-release head processing, relying solely on station weight detection cannot distinguish whether the weight abnormality is due to assembly failure of the part itself or a false weight abnormality caused by the part's tilted, suspended, or offset posture. This easily leads to qualified workpieces being mistakenly judged as scrapped due to posture deviation, ultimately resulting in material waste and a high rate of defective finished products. Summary of the Invention

[0005] In order to improve the pass rate of quick-release hub products, this invention provides a method and apparatus for processing quick-release hubs.

[0006] In a first aspect, the present invention provides a method for processing quick-release hubs, employing the following technical solution: A method for manufacturing a quick-release hub, comprising: S1: In response to the quick-release head protective cover loading signal, perform the protective cover loading operation, obtain the rotation angle, determine the first effective station number based on the rotation angle, and obtain the first station position corresponding to the first effective station number in real time. S2: Determine the current pressing and positioning component number based on the first workstation position, and control the pressing and positioning component corresponding to the current pressing and positioning component number to perform the pressing operation; S3: After the pressing operation is performed, the protective cover placement signal is obtained. If the protective cover placement signal exists, the position of the work station to be processed is determined in real time. When the position of the work station to be processed falls into the preset quick-release head loading position, the quick-release head loading operation is performed. S4: After the quick-release head loading operation is performed, the weight of the second processing station is collected; S5: When the weight of the second processing station falls within the preset effective positioning weight range of the quick-release head, determine the number of the second effective station and obtain the position of the second station corresponding to the number of the second effective station in real time. S6: When the second workstation position falls into the preset position of the second clamping component, control the second clamping component to perform the clamping operation and obtain the clamping success signal; S7: If a successful clamping signal exists, determine the final valid workstation number and the position of the final valid workstation corresponding to the final valid workstation number. S8: When the final effective workstation position falls into the preset unloading position, control the unloading pickup component to perform the unloading operation; S50: When the weight of the second processing station does not fall within the effective positioning weight range of the quick-release head, obtain the preset quick-release head limit block pushing parameters; S51: Perform quick-release head limit operation according to the quick-release head limit block push parameters; S52: After performing the quick-release head limit operation, perform the quick-release head pressing operation and obtain the corrected weight of the second processing station; S53: When the weight of the second processing station does not fall within the effective positioning weight range of the quick-release head, determine the quick-release head discard station number to perform the quick-release head push-away operation. S54: When the weight of the second processing station falls within the effective positioning weight range of the quick-release head, determine the second effective station number and the position of the second effective station corresponding to the second effective station number, and execute steps S6 to S8.

[0007] By adopting the above technical solution, at each process node of quick-release head processing, the weight of the workstation is collected multiple times for qualification judgment. This can promptly identify the misalignment of the parts, prevent defective parts from flowing into the next processing step, and perform limit correction for abnormal quick-release head placement. It is not necessary to directly judge the quick-release head as waste and reject it. It can also correct the weight detection abnormality caused by the placement posture deviation, reduce material waste, and ensure that only qualified quick-release heads can enter the subsequent pressing process. This effectively reduces the defect rate of the final product and improves the overall processing quality and qualification rate of hub quick-release heads.

[0008] Optionally, a method for outputting a protective cover placement signal is also included, the method comprising: S30: Get the pressing weight at the current workstation; S31: If the pressing weight of the current workstation falls within the preset effective pressing weight range, output a protective cover placement signal; S32: If the pressing weight of the current station does not fall within the effective pressing weight range, perform a station rotation operation to make the first station position fall into the preset protective cover pressing position, and perform a pressing operation. S33: After performing the clamping operation, obtain the current clamping weight at the workstation; S34: If the current pressing weight falls within the effective pressing weight range, output a protective cover placement signal.

[0009] By adopting the above technical solution, the protective cover that fails to be positioned after initial pressing can be tightened and corrected a second time. There is no need to directly judge the part as scrap and discard it. It can correct the abnormal positioning caused by the initial placement posture deviation, reduce unnecessary material waste, reduce processing costs, and at the same time ensure that only the protective cover that is positioned correctly enters the subsequent process, thus maintaining the stability of processing quality.

[0010] Optionally, it also includes a method for picking up the discarded quick-release head protective cover if the current pressing weight does not fall within the effective pressing weight range. This method includes: S340: If the current pressing weight does not fall within the effective pressing weight range, determine the abandoned station number; S341: Real-time acquisition of the location of the abandoned quick-release head protective cover station corresponding to the abandoned station number based on the abandoned station number; S342: When the waste quick-release head protective cover station position falls into the preset waste disposal position, find the preset waste quick-release head protective cover picking parameters, and control the waste picking component to perform the waste quick-release head protective cover picking operation according to the waste quick-release head protective cover picking parameters.

[0011] By adopting the above technical solution, protective covers that are still unqualified after secondary clamping and correction can be promptly removed. This avoids unqualified protective covers from occupying processing resources at the processing station and prevents unqualified workpieces from flowing into subsequent quick-release head feeding and assembly processes, thus ensuring the smooth flow of processing stations and maintaining processing efficiency.

[0012] Optionally, methods for performing the quick-release head push-away operation include: S530: Obtain the contact pressure corresponding to the discarded quick-release head limit block; S531: If the contact pressure falls within the preset effective contact pressure range, output a rotation stop signal, search for the preset waste head pushing parameters, and control the waste pushing component to perform the waste head pushing operation according to the waste head pushing parameters. S532: After the discarded head removal and pushing operation is performed, determine the valid quick-release head protective cover station number, and obtain the valid quick-release head protective cover station position corresponding to the valid quick-release head protective cover station number in real time. S533: When the effective quick-release head protective cover station position falls into the preset protective cover loading position, output a loading stop signal and output the effective quick-release head protective cover station position as the first station position to execute steps S2 to S7.

[0013] By adopting the above technical solution, quick-release heads that are still unqualified after positioning and correction are promptly pushed away and removed. At the same time, the workstations with only qualified protective covers remaining are sent back to the protective cover feeding stage for replenishment. There is no need to discard the still intact protective covers directly, which further reduces the waste of raw materials and controls the processing cost while ensuring processing quality.

[0014] Optionally, the method for determining the current pressing and positioning component number based on the first workstation position and controlling the pressing and positioning component corresponding to the current pressing and positioning component number to perform the pressing operation includes: S20: If the first workstation position falls into the preset first pressing position, obtain the effective weight corresponding to the first effective workstation number; S21: When the effective weight does not fall within the preset reliable effective weight range, output a material disengagement signal; S22: In response to the material feeding disconnection signal, the first valid station number is output as the empty station number, and the first valid station number is re-determined based on the rotation angle. S23: Real-time acquisition of the rotation angle of the empty space corresponding to the empty space number. When the rotation angle of the empty space reaches the preset circumferential rotation angle threshold, the protective cover loading operation is executed.

[0015] By adopting the above technical solution, empty workstations where protective covers have not been successfully loaded can be identified in advance, and unnecessary subsequent processing steps can be skipped directly, avoiding empty workstations from occupying processing resources to perform invalid processes, thereby improving the overall operating efficiency of the processing equipment.

[0016] Optionally, it also includes a method for performing a scrap pickup operation when no compaction success signal is present, the method comprising: S70: When there is no clamping success signal, determine the clamping failure station number and the clamping failure station location corresponding to the clamping failure station number; S71: When the damaged workstation position falls into the preset waste picking position, the waste picking operation is executed.

[0017] By adopting the above technical solution, unqualified finished products that have not been properly pressed and assembled can be removed in a timely manner, preventing defective products from flowing into the subsequent unloading process and mixing with qualified finished products. This further ensures the final product qualification rate and reduces the cost of subsequent manual sorting and screening.

[0018] Secondly, the present invention provides a quick-release head processing device for hubs, which adopts the following technical solution: A quick-release hub processing device, applied to the quick-release hub processing method described above, includes a first vibratory feeding device, a processing rotating assembly fixedly connected to the first vibratory feeding device, a second vibratory feeding device fixedly connected to the processing rotating assembly, a quick-release hub limiting assembly fixedly connected to the processing rotating assembly, a pressing and positioning assembly fixedly connected to the processing rotating assembly, a clamping assembly fixedly connected to the processing rotating assembly, a waste pushing assembly fixedly connected to the processing rotating assembly, a waste picking assembly fixedly connected to the processing rotating assembly, and a discharge picking assembly fixedly connected to the processing rotating assembly. The machining rotation assembly includes a machining rotation body, a machining rotation disc disposed inside the machining rotation body and rotatably connected to the machining rotation body, a machining rotation shaft fixedly connected to the machining rotation disc, a machining disc drive motor fixedly connected to the machining rotation shaft and used to drive the machining rotation shaft to rotate, a support disc fixedly connected to the machining rotation body, a quick-release head protective cover limiting block fixedly connected to the machining rotation body, a waste quick-release head limiting block fixedly connected to the machining rotation body, a support base fixedly connected to the machining rotation body, a quick-release head waste collection container fixedly connected to the support base, a hub quick-release head waste collection container fixedly connected to the support base, and a feeding container fixedly connected to the support base.

[0019] By adopting the above technical solution, multi-station cyclic flow is realized by relying on the processing rotating components. Combined with a complete set of mechanisms for dual-path vibration feeding, limit correction, pressing and clamping, waste material removal and finished product unloading, it fully adapts to the entire process of the aforementioned processing method. It provides a hardware carrier for multi-node weight detection, posture correction and defect removal, and realizes continuous processing of hub quick-release heads.

[0020] Optionally, the quick-release head limiting assembly includes a quick-release head limiting body fixedly connected to the support base, a quick-release head limiting block slidably connected to the quick-release head limiting body, and a limiting block driving mechanism fixedly connected to the limiting body and driving the quick-release head limiting block to slide. The pressing and positioning assembly includes a pressing body fixedly connected to the support base and a pressing drive mechanism fixedly connected to the pressing body.

[0021] By adopting the above technical solution, the limit block driving mechanism drives the quick-release head limit block to extend and slide, thereby realizing the height limit and posture correction of the quick-release head; at the same time, the pressing driving mechanism can stably output the preset light pressure to complete the sealing and pressing of the protective cover and auxiliary weight detection, ensuring the accuracy of the part placement detection.

[0022] Optionally, the waste pushing assembly includes a pushing base fixedly connected to the support disc, a pushing rod slidably connected to the pushing base, and a waste pushing block fixedly connected to the pushing rod; The waste picking assembly includes a picking base fixedly connected to the processing rotating body, a first picking rotating shaft rotatably connected to the picking base, a picking bracket fixedly connected to the first picking rotating shaft, a second picking rotating shaft slidably connected to the picking bracket, and a picking robotic arm rotatably connected to the second picking rotating shaft. The unloading and picking assembly includes an unloading base fixedly connected to the processing rotating body, a first unloading rotating shaft rotatably connected to the unloading base, an unloading bracket fixedly connected to the first unloading rotating shaft, a second unloading rotating shaft slidably connected to the unloading bracket, and an unloading robotic arm rotatably connected to the second unloading rotating shaft. The clamping assembly includes a clamping body fixedly connected to the support base and a clamping drive mechanism fixedly connected to the clamping body.

[0023] By adopting the above technical solutions, the push-off waste cleaning, robotic arm picking and rejecting, and automatic finished product unloading structures are integrated respectively. With the clamping drive mechanism to provide stable clamping force, abnormal parts can be pushed away, damaged workpieces can be picked up, defective finished products can be rejected, and qualified finished products can be automatically unloaded. The structure has a clear division of labor and coordinated actions, which can be adapted to the classification and processing of different types of defective products. The overall equipment operates stably and has a high degree of automation.

[0024] In summary, the present invention has at least one of the following beneficial technical effects: 1. Weight detection and judgment logic is set up in multiple processes such as protective cover loading, pressing and positioning, quick-release head assembly, and pressing and molding. Based on the pressure sensor, the weight of the station is collected in real time. Based on this, abnormal conditions such as parts being suspended or tilted, not in place, or missing are identified, effectively intercepting the flow of defective parts and significantly improving the overall processing qualification rate of hub quick-release heads. 2. By combining the rotation angle of the multi-station turntable to achieve precise positioning of the workstation, the linkage of multiple mechanisms such as pressing, clamping, limiting, waste pushing, robotic arm picking and finished product unloading is coordinated to realize automated linkage operation, avoid ineffective processing at empty workstations, and effectively improve the overall processing efficiency of the equipment; 3. For abnormal placement of different parts such as protective covers and quick-release heads, secondary clamping and correction and limit correction processes are set up respectively. Repairable workpieces with posture deviations are corrected and reused to avoid the single rejection method, reduce raw material waste and reduce production and processing costs.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] This invention discloses a processing device for quick-release heads for flower hubs. (Refer to...) Figure 1 and Figure 2A quick-release head processing device for a hub includes a first vibratory feeding device 1, a processing rotation component 2, a second vibratory feeding device 3, a pressing and positioning component, a quick-release head limiting component 5, a clamping component, a waste pushing component 7, a waste picking component 8, and a material unloading and picking component 9.

[0029] Reference Figure 2 The hub quick-release head processing area is formed by the processing rotation component 2, pressing and positioning component, quick-release head limiting component 5, clamping component, waste pushing component 7, waste picking component 8, and unloading picking component 9.

[0030] Reference Figure 2 The machining rotating assembly 2 includes a machining rotating body 21, a machining rotating disk 22, a machining rotating shaft 23, a machining disk drive motor, a support disk 24, a quick-release head protective cover limiting block 212, a support base 25, a quick-release head waste collection container 26, a hub quick-release head waste collection container 27, a waste quick-release head limiting block 213, and a discharge container 28. The inner sidewall of the machining rotating body 21 is fixedly connected to the circumferential outer surface of the support disk 24. The support disk 24 has a first rotating hole. One end of the machining rotating shaft 23 passes through the rotating hole and is fixedly connected to the drive shaft of the machining disk drive motor, which is fixedly installed inside the machining rotating body 21. The machining rotating disk 22 has a second rotating hole that mates with the machining rotating shaft 23, and the machining rotating shaft 23 passes through the second rotating hole and is fixedly connected to the machining rotating disk 22. The machining disk drive motor drives the machining rotating shaft 23 to rotate, thereby driving the machining rotating disk 22 to rotate. The outer wall of the machining rotating body 21 is fixedly connected to the support base 25.

[0031] Reference Figure 2 The first vibrating feeding device 1 includes a first vibrating mechanism 11 and a first transmission mechanism 12. The first vibrating mechanism 11 is a vibrating plate, used to automatically sort and orient the randomly stacked quick-release protective covers through high-frequency directional vibration, ensuring all protective covers are conveyed upwards along a spiral track with their openings facing upwards. The first transmission mechanism 12 is a linear feeder, one end of which smoothly connects to the outlet of the vibrating plate. Through slight linear vibration, it conveys the sorted upright protective covers to the processing station. The other end of the linear feeder is fixedly connected to the processing rotating body 21.

[0032] Reference Figure 2The second vibratory feeding device 3 includes a second vibration mechanism 31 and a second transmission mechanism 32. The second vibration mechanism 31 and the second transmission mechanism 32 have the same function as the first vibration mechanism 11 and the first transmission mechanism 12 mentioned above, the difference being that the second vibratory feeding device 3 performs the feeding operation of the quick-release head. One end of the second transmission mechanism 32 is fixedly connected to the second vibration mechanism 31, and the other end is fixedly connected to the processing rotating body 21. Both the first and second vibratory feeding devices are common devices in the art.

[0033] Reference Figure 2 The machining rotating disk 22 and the inner wall of the machining rotating machine body 21 form a machining annular groove. Eight machining limiting grooves are arranged circumferentially at one end of the machining rotating disk 22. Specifically, the machining limiting grooves are divided into quick-release head protective cover limiting grooves and quick-release head limiting grooves. When the quick-release head protective cover first falls into the quick-release head protective cover limiting groove, and then the quick-release head loading operation is performed, causing the quick-release head to fall above the quick-release head protective cover located in the quick-release head protective cover limiting groove, and be limited by the quick-release head limiting groove. A pressure sensor is installed at the bottom of the quick-release head protective cover limiting groove to detect the weight of the part in the machining limiting groove, to confirm whether the part has fallen normally into the machining limiting groove.

[0034] Reference Figure 3 In this embodiment, eight processing limit slots are assigned corresponding numbers, arranged counterclockwise as follows: Processing Limit Slot 1 221, Processing Limit Slot 222, Processing Limit Slot 3 223, Processing Limit Slot 4 224, Processing Limit Slot 5 225, Processing Limit Slot 6 226, Processing Limit Slot 7 227, and Processing Limit Slot 8 228. A corresponding angular mapping relationship is established between the processing rotation shaft 23 and Processing Limit Slot 1 221. When the processing rotation shaft 23 rotates to 0 degrees, Processing Limit Slot 1 221 is located at the loading position of the quick-release head protective cover, that is, the end adjacent to the first transmission mechanism 12 and away from the first vibrating loading device 1. When the processing rotation shaft 23 rotates to 0 degrees, the corresponding positions of the processing limit slot numbers are as follows: Figure 3 As shown.

[0035] Reference Figure 2 and Figure 3The pressing and positioning assembly includes a pressing body and a pressing drive mechanism. One end of the pressing body is fixedly connected to the support base 25, and the other end is fixedly connected to the pressing drive mechanism. There are two pressing and positioning assemblies: a first pressing and positioning assembly 41 and a second pressing and positioning assembly 42, respectively positioned at positions where the first processing limit groove 221 corresponds to the processing rotation shaft 23 rotating counterclockwise to 45 degrees and 180 degrees. The clamping assembly includes a clamping body and a clamping drive mechanism. One end of the clamping body is fixedly connected to the support base 25, and the other end is fixedly connected to the clamping drive mechanism. There are two clamping assemblies: a first clamping assembly 61 and a second clamping assembly 62, respectively positioned at positions where the processing rotation shaft 23 rotates counterclockwise to 90 degrees and 225 degrees, corresponding to the support base 25 areas of the first processing limit groove 221. The quick-release head protective cover limiting block 212 is fixedly connected to the machining rotating body 21. Specifically, it is located in the area of ​​the machining rotating body 21 corresponding to the first machining limiting groove 221 when the machining rotating shaft 23 rotates counterclockwise to a 50° angle. It is used to collide with the quick-release head protective cover that falls into the machining limiting groove in an abnormal posture, so that it can adjust its posture under the groove structure of the machining limiting groove.

[0036] In addition, the feeding end of the first transmission mechanism 12 is located in the area of ​​the processing rotating body 21 corresponding to the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 0°, and is used to feed the quick-release head protective cover; the second transmission mechanism 32 is located in the area of ​​the processing rotating body 21 corresponding to the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 135°, and is used to feed the quick-release head.

[0037] Reference Figure 2 The quick-release head limiting assembly 5 includes a quick-release head limiting body 51, a quick-release head limiting block 52, and a limiting block drive mechanism. One end of the quick-release head limiting body 51 is fixedly connected to the support base 25. The quick-release head limiting body 51 has a motor placement slot, and the limiting block drive mechanism is placed in the motor placement slot. The end of the quick-release head limiting body 51 near the motor placement slot also has a limiting block sliding groove. One end of the quick-release head limiting block 52 is fixedly connected to the drive shaft of the limiting block drive mechanism. Under the limiting fit of the limiting block sliding groove and the drive of the limiting block drive mechanism, the quick-release head limiting block 52 slides along the length direction of the limiting block sliding groove. Among them, the outer circumferential wall of the machining rotating body 21 near the quick-release head limiting block 52 has a quick-release head correction hole 211 for the quick-release head limiting block 52 to pass through. The quick-release head limiting block 52 passes through the quick-release head correction hole 211 to limit the horizontal placement height of the quick-release head that has not fallen into the machining limiting groove normally, so that the quick-release head collides with the quick-release head limiting block 52 and falls into the machining limiting groove in the correct posture through the groove structure of the machining limiting groove.

[0038] Reference Figure 2 and Figure 3The waste pushing assembly 7 includes a pushing base 71, a pushing rod 72, and a waste pushing block 73. The pushing base 71 is fixedly connected to the end of the support disc 24 away from the processing rotating disc 22. A pushing groove is provided on one side of the pushing base 71 for the pushing rod 72 to slide, and a pushing cylinder is installed at the bottom of the pushing groove. The piston rod of the pushing cylinder is fixedly connected to one end of the pushing rod 72, and the end of the pushing rod 72 away from the pushing base 71 is fixedly connected to the waste pushing block 73. A pushing hole is provided on the inner side wall of the processing rotating body 21 for the waste pushing block 73 to pass through. The waste quick-release head limiting block 213 is fixedly connected to the processing rotating body 21, specifically located in the area of ​​the processing rotating body 21 corresponding to the first processing limiting groove 221 when the processing rotating shaft 23 rotates counterclockwise to an angle of 225 degrees, and is used to limit the continued movement of the quick-release head. The quick-release head waste collection container 26 is fixedly connected to one end of the support base 25 and is correspondingly set with the waste pushing component 7. When there is a quick-release head that cannot be processed further, the processing rotation shaft 23 rotates counterclockwise to an angle of 225 degrees. The waste quick-release head limiting block 213 will restrict the movement of the quick-release head and, together with the waste pushing component 7, push the quick-release head, causing the quick-release head to pass through the pushing hole and fall into the quick-release head waste collection container 26.

[0039] Reference Figure 2 and Figure 3 The waste picking assembly 8 includes a picking base, a first picking rotating shaft, a picking bracket, a second picking rotating shaft, and a picking robotic arm. The picking base is specifically installed in the area of ​​the processing rotating body 21 corresponding to the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to a 270° angle. One end of the picking base is fixedly connected to the processing rotating body 21, and the other end is rotatably connected to the first picking rotating shaft. The picking bracket is fixedly connected to the end of the first picking rotating shaft away from the picking base. A picking sliding groove is provided on one side of the picking bracket for the second picking rotating shaft to slide, and the second picking rotating shaft is inserted into the picking sliding groove and slidably connected to the picking base. The picking robotic arm is rotatably connected to the second picking rotating shaft and is used to pick up the quick-release head protective cover and quick-release head that have failed to be processed within the processing limit groove. One end of the hub quick-release head waste collection container 27 is fixedly connected to the support base 25 and is correspondingly set with the waste picking component 8 so that the waste picking component 8 can grab non-finished hub quick-release heads and drop them into the hub quick-release head waste collection container 27.

[0040] Reference Figure 4The unloading and picking assembly 9 includes an unloading base 91, a first unloading rotating shaft 92, an unloading bracket 93, a second unloading rotating shaft 94, and an unloading robotic arm 95. One end of the unloading base 91 is fixedly connected to the processing rotating body 21, specifically installed in the area of ​​the processing rotating body 21 corresponding to the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to an angle of 315°. The end of the unloading base 91 away from the processing rotating body 21 is rotatably connected to the first unloading rotating shaft 92. The end of the first unloading rotating shaft 92 away from the unloading base 91 is fixedly connected to the unloading bracket 93. A unloading sliding groove 931 is provided on one side of the unloading bracket 93 for the second unloading rotating shaft 94 to slide. The second unloading rotating shaft 94 is embedded in the unloading sliding groove 931 and slides along the length direction of the unloading sliding groove 931. The unloading robotic arm 95 is rotatably connected to the second unloading rotating shaft 94, and is used to grab the finished hub quick-release head that has been processed in the processing limit groove. One end of the unloading container 28 is fixedly connected to the support base 25 and is correspondingly set with the unloading pickup component 9 so that the unloading pickup component 9 can grab the finished hub quick-release head and drop it into the unloading container 28.

[0041] When the first processing limiting groove 221 rotates counterclockwise to a 45-degree angle via the processing rotating shaft 23, it indicates that the first processing limiting groove 221 has performed the loading operation of the quick-release head protective cover. It is then necessary to control the first pressing positioning component 41 to press the quick-release head protective cover within the groove and obtain data from the pressure sensor at the bottom of the groove to determine if the quick-release head protective cover has fallen normally into the processing limiting groove. When it is determined that the quick-release head protective cover has fallen normally into the processing limiting groove, the processing rotating shaft 23 is controlled to rotate counterclockwise to a 90-degree angle, and the first pressing component 61 is controlled to perform a pressing operation, obtaining data from the pressure sensor at the bottom of the groove to determine if the quick-release head protective cover is in the correct position. When it is determined that the quick-release head protective cover is in the correct position, the processing rotating shaft 23 is controlled to rotate counterclockwise to a 135-degree angle to perform the loading operation of the quick-release head. After the quick-release head is loaded, the machining rotating shaft 23 is controlled to rotate counterclockwise to 180 degrees, and the second pressing and positioning component 42 is controlled to press to determine whether the quick-release head has fallen into the machining limit groove. Because the quick-release head is closer to the pressing mechanism than the quick-release head protective cover, the pressing mechanism of the second pressing and positioning component 42 only acts on the quick-release head compared to the first pressing and positioning component 41. When there is no quick-release head in the machining limit groove, the pressing mechanism will not press the quick-release head protective cover. At this time, the data from the pressure sensor can be used to determine whether the quick-release head has fallen into place normally. The control machining rotating shaft 23 rotates counterclockwise to a position of 225 degrees. Before the control of the second clamping component 62 to perform the clamping operation, it will judge whether the quick release head is in the correct position. If the quick release head is not in the machining limit groove, the control of the waste pushing component 7 will push the quick release head away. When the quick release head is in the correct position, the control of the second clamping component 62 will perform the clamping operation to press the quick release head and the quick release head protective cover together to form a finished hub quick release head. At the same time, the pressure sensor can also obtain the total weight after pressing to judge whether the pressing meets the requirements. After pressing is completed, the control machining rotating shaft 23 rotates counterclockwise to a 270-degree angle position. If the pressing does not meet the requirements, the waste picking component 8 is triggered to grab the non-finished hub quick-release head and drop it into the hub quick-release head waste collection container 27. If the pressing meets the requirements, the waste picking component 8 does not perform the operation of grabbing the non-finished hub quick-release head and dropping it into the hub quick-release head waste collection container 27. The workpiece continues to rotate with the machining rotating disk 22 to a 315-degree angle position, triggering the unloading picking component 9. The unloading picking component 9 picks up the finished qualified hub quick-release head and drops it into the unloading container 28, completing the entire processing process.

[0042] Based on the same inventive concept, this invention provides a method for processing quick-release heads for hubs.

[0043] Reference Figure 5 A method for manufacturing quick-release heads for hubs, comprising: Step S1: In response to the quick-release head protective cover loading signal, perform the protective cover loading operation, obtain the rotation angle, determine the first effective station number based on the rotation angle, and obtain the first station position corresponding to the first effective station number in real time.

[0044] The quick-release head protective cover loading signal refers to the trigger signal issued by the control system to start the quick-release head protective cover loading process. Specifically, this signal is triggered when the weight in the processing limit groove located under the first transmission mechanism 12 is 0 and the processing rotation shaft 23 reaches the preset default rotation angle. The default rotation angle refers to the 0-degree angle corresponding to the first processing limit groove 221. At this time, the station is located at the discharge end of the first transmission mechanism 12 and can receive the quick-release head protective cover sent out by the first vibratory plate.

[0045] The protective cover loading operation refers to the control system controlling the first vibrating loading device 1 to transport the sorted and oriented quick-release head protective cover to the corresponding processing limit groove, thus completing the loading of the quick-release head protective cover. At the same time, the pressure sensor uploads the weight data in the groove in real time to confirm that the quick-release head protective cover has been unloaded.

[0046] The first valid workstation number refers to the preset assigned number corresponding to the machining limit groove of the currently receiving part. The first workstation position refers to the actual angular position of the machining rotation shaft 23 after the corresponding machining limit groove has rotated.

[0047] The rotation angle refers to the real-time angle value when the machining rotating shaft 23 drives the machining rotating disk 22 to rotate. It corresponds one-to-one with the position of the eight machining limit slots (e.g., 0° of the rotating shaft corresponds to station number one, and 45° corresponds to station number two), and is used to locate the specific position of the current station.

[0048] Step S2: Determine the current pressing and positioning component number based on the first workstation position, and control the pressing and positioning component corresponding to the current pressing and positioning component number to perform the pressing operation.

[0049] The current press positioning component number refers to the press positioning component number assigned to the two press positioning components that performs the press operation at the first workstation position. The press positioning component number corresponds one-to-one with the rotation angle and workstation position of the machining rotating shaft 23 (press positioning component 41 corresponds to the machining rotating shaft 23 rotating counterclockwise to a 45° position, and press positioning component 42 corresponds to the machining rotating shaft 23 rotating counterclockwise to a 180° position), and is used to match the corresponding press positioning component based on the first workstation position (the real-time angle position of the machining limit groove).

[0050] The pressing operation refers to the control system controlling the corresponding numbered pressing and positioning component to perform a light-pressure positioning action. Specifically, the pressing drive mechanism drives the pressing head to vertically press the quick-release head protective cover in the machining limit groove corresponding to the first effective work station number with a preset light pressure. The light pressure is the amount that will not cause deformation to the quick-release head protective cover, but is only used to press the protective cover to fit the bottom of the machining limit groove, so that the pressure sensor can accurately obtain the weight of the part in the groove.

[0051] Step S3: After the pressing operation is performed, the protective cover placement signal is obtained. If the protective cover placement signal exists, the position of the processing station is determined in real time. When the position of the processing station falls into the preset quick-release head loading position, the quick-release head loading operation is performed.

[0052] The protective cover placement signal is a confirmation signal issued by a pressure sensor installed in the machining limit groove after detecting that the weight in the groove has fallen into the effective pressing weight range. When the protective cover placement signal exists, it means that the protective cover has accurately fallen into the machining limit groove, and the subsequent pressing operation of the first pressing component 61 is not required. Only the subsequent pressing operation of the second pressing component 62 on the quick-release head protective cover and quick-release head is needed. The pressing operation refers to the operation in which the second pressing component 62 applies a set pressing force to press the two tightly together and fix them into the finished hub quick-release head. This operation is for the case where there is no protective cover placement signal, and controls the first pressing component 61 to perform a pressing operation on the quick-release head protective cover to further check whether the quick-release head protective cover is in place normally. Since the quick-release head protective cover limit block 212 will correct the quick-release head protective cover that is not in the correct position after the pressing operation, it will cause the quick-release head protective cover that is not in the correct position to fall into the processing limit groove normally. Therefore, it is necessary to perform a pressing operation through the first pressing component 61 to reproduce the effect of the pressing operation performed by the first pressing positioning component 41.

[0053] The position of the workstation to be processed refers to the real-time spatial position of the processing limiting groove (the groove corresponding to the first effective workstation) that carries the quick-release head protective cover after the pressing operation is performed, as the processing rotating shaft 23 rotates. This position is determined by the correspondence between the real-time rotation angle of the processing rotating shaft 23 and the workstation number, and is used to determine whether the workstation has been transferred to the preset position for feeding the quick-release head.

[0054] The quick-release head loading position refers to the specific angular position used to load the quick-release head body, corresponding to the position of the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 135° (i.e., the docking position between the second transmission mechanism 32 and the processing rotating disk 22).

[0055] The quick-release head feeding operation refers to the operation in which the control system controls the second vibrating feeding device 3 to transport the sorted and oriented quick-release head body to the corresponding processing limit groove. Specifically, the second vibration mechanism 31 (vibrating plate) automatically sorts and orients the messy quick-release heads, and then the second transmission mechanism 32 (linear feeder) smoothly transports the quick-release heads to the processing limit groove at the quick-release head feeding position (falling above the already positioned quick-release head protective cover).

[0056] Step S4: After the quick-release head loading operation is performed, the weight of the second processing station is collected.

[0057] The weight of the second processing station refers to the total weight value collected by the pressure sensor placed in the processing limit groove, which is generated by the combined action of the quick-release head protective cover and the quick-release head in the processing limit groove. It is used to determine whether the quick-release head has been properly positioned.

[0058] Step S5: When the weight of the second processing station falls within the preset effective positioning weight range of the quick-release head, determine the number of the second effective station and obtain the position of the second station corresponding to the number of the second effective station in real time.

[0059] The effective weight range for quick-release heads refers to the standard weight range that the system pre-calibrates and stores. It is the overall weight threshold range of the quick-release head protective cover and the qualified hub quick-release head superimposed. It is used to determine whether the quick-release head is properly assembled and positioned by using data from the bottom pressure sensor.

[0060] The second valid workstation number refers to the number corresponding to the machining limiting groove that carries both the quick-release head protective cover and the hub quick-release head after the quick-release head feeding operation is completed. It is the valid workstation identifier that the machining limiting groove corresponding to this number is matched for the subsequent transfer to the pressing process.

[0061] The second workstation position refers to the position of the processing limit groove corresponding to the second effective workstation number after it has been continuously rotated with the processing rotation shaft 23. It is used to match the installation position of the corresponding second clamping component 62 to perform the clamping operation.

[0062] When the weight at the second processing station falls within the effective positioning weight range of the quick-release head, it indicates that the hub quick-release head has been completely and stably placed into the processing limit groove and positioned above the quick-release head protective cover, without any tilting, thus meeting the processing conditions for subsequent pressing and clamping.

[0063] Step S6: When the second workstation position falls into the preset position of the second clamping component, control the second clamping component 62 to perform the clamping operation and obtain the clamping success signal.

[0064] The position of the second clamping component refers to the pre-set fixed processing angle position, which corresponds to the support seat 25 area of ​​the first processing limit groove 221 when the processing rotation shaft 23 rotates counterclockwise to 225°. This area is the fixed installation and clamping operation area of ​​the second clamping component 62.

[0065] A successful pressing signal is emitted when the pressure sensor detects that the total weight after pressing falls within the preset acceptable weight range for the finished product. This indicates that the quick-release head and its protective cover have been successfully pressed together, meeting the dimensions and assembly requirements of the finished product. If no successful pressing signal is received, it means that the pressing assembly does not meet the requirements, and the workpiece is considered a non-finished product and requires subsequent scrap disposal. The acceptable weight range for the finished product refers to the preset calibrated threshold range of the overall weight of the acceptable finished product hub quick-release head. It is determined by the standard total weight after pressing the quick-release head protective cover and the acceptable quick-release head together, and is used to determine whether the pressing assembly is acceptable based on the weight data after pressing.

[0066] When the second work station position falls into the position of the second clamping component, it means that the work station carrying the quick-release head protective cover and quick-release head has been transferred to the clamping processing area and can perform the clamping operation. At this time, the drive mechanism of the second clamping component 62 drives the clamping head to move downward, and uses the preset clamping force to press the quick-release head and quick-release head protective cover together, so that the two are fixed into a complete finished hub quick-release head.

[0067] Step S7: If a successful clamping signal is present, determine the final valid workstation number and the position of the final valid workstation corresponding to the final valid workstation number.

[0068] The final valid workstation number refers to the workstation number corresponding to the processing limit groove where the weight in the groove falls within the qualified weight range of the finished product after the pressing operation of the No. 2 pressing component 62.

[0069] The final effective workstation position refers to the real-time position of the machining limit groove corresponding to the final effective workstation number, formed by the rotation of the machining rotating disk 22.

[0070] Step S8: When the final effective workstation position falls into the preset unloading position, control the unloading pickup component 9 to perform the unloading operation.

[0071] The unloading operation refers to the unloading robotic arm 95 of the unloading pickup component 9 grabbing the finished qualified finished product hub quick-release head, taking the finished product out of the processing limit groove, then rotating it above the unloading container 28, releasing the gripping and dropping the qualified finished product hub quick-release head into the unloading container 28, completing the unloading and collection of a single finished product. At the same time, after the unloading is completed, the unloading robotic arm 95 resets and waits for the next unloading trigger command.

[0072] When the final effective workstation position falls into the unloading position, it indicates that the processing limit slot carrying the qualified finished hub quick-release head has been transferred to the unloading operation area. At this time, the unloading pickup component 9 is controlled to perform the unloading operation. Thus, the complete processing flow of a single qualified hub quick-release head is completed. The processing rotation shaft 23 continuously drives each processing limit slot to rotate counterclockwise, and the above processing steps are executed in a cycle, thereby realizing the automated continuous processing and production of hub quick-release heads.

[0073] Reference Figure 6 Step S50: When the weight of the second processing station does not fall within the effective positioning weight range of the quick-release head, obtain the preset quick-release head limit block pushing parameters.

[0074] The quick-release head limit block push parameter refers to the push distance of the quick-release head limit block 52, which is pre-stored by the system and set for the quick-release head attitude adjustment.

[0075] When the weight of the second processing station does not fall within the effective positioning weight range of the quick-release head, it indicates that the quick-release head has not completely fallen into the processing limit groove, and there are abnormal positioning problems such as tilting or misalignment. At this time, it is necessary to trigger the subsequent quick-release head pushing operation.

[0076] Step S51: Perform quick-release head limit operation according to the quick-release head limit block push parameters.

[0077] The quick-release head limiting operation refers to the quick-release head limiting block 52 being inserted into the quick-release head straightening hole 211 to limit the height of the quick-release head body that is not fully in place, and to allow the tilted quick-release head to fall into the center position of the machining limiting groove under the limiting action of the quick-release head limiting block 52.

[0078] Step S52: After performing the quick-release head limit operation, perform the quick-release head pressing operation and obtain the corrected weight of the second processing station.

[0079] The corrected weight for the second processing station refers to the actual total weight borne by the bottom of the current processing limit groove, which is re-collected by the pressure sensor after the quick-release head limit block 52 completes its posture correction operation and the second pressing positioning component 42 performs the pressing operation. This weight is used to determine whether the quick-release head body has been properly positioned after posture correction. Since the quick-release head is present on the quick-release head protective cover in the processing limit groove at this time, the downward pressing distance of the second pressing positioning component 42 is shorter than the downward pressing distance of the first pressing positioning component 41.

[0080] Step S53: When the weight of the second processing station does not fall within the effective positioning weight range of the quick-release head, determine the quick-release head discard station number to perform the quick-release head push-away operation.

[0081] When the weight of the second processing station does not fall within the effective positioning weight range of the quick-release head, it means that even after posture correction and pressing operations, the quick-release head body still cannot fall into the processing limit groove in the correct posture. At this time, performing the pressing operation will cause the quick-release head protective cover, which should be normal, to be damaged. Therefore, the quick-release head cannot meet the subsequent pressing and assembly requirements. This station needs to be marked as the head removal waste station. Subsequently, the quick-release head push-away operation is performed to push the quick-release head to the quick-release head waste collection container 26.

[0082] The quick-release head push-away operation refers to the operation of pushing out quick-release heads that cannot be properly positioned from the processing limit groove to the corresponding waste collection container by using the waste push-away component 7.

[0083] Step S54: When the weight of the second processing station falls within the effective positioning weight range of the quick-release head, determine the second effective station number and the position of the second effective station corresponding to the second effective station number, and then execute steps S6 to S8.

[0084] When the weight of the second processing station falls within the effective positioning weight range of the quick-release head, it indicates that after posture correction and secondary pressing, the quick-release head body has been adjusted to the correct posture and fallen into the processing limit groove, and subsequent clamping and assembly operations can be carried out normally.

[0085] This also includes a method for outputting a protective cover placement signal, the method comprising: Step S30: Obtain the pressing weight at the current workstation.

[0086] The current station pressing weight refers to the actual total weight borne by the bottom of the current processing limit groove, collected by the pressure sensor after the pressing and positioning component completes the pressing operation.

[0087] Step S31: If the pressing weight of the current workstation falls within the preset effective pressing weight range, output a protective cover placement signal.

[0088] The effective pressing weight range refers to the threshold range that includes only the weight of a single quick-release head protective cover. It is used to determine whether the quick-release head protective cover has accurately and completely fallen into the processing limit groove based on the actual weight currently collected, and whether there are any abnormal situations such as skewness or jamming.

[0089] If the pressing weight at the current workstation falls within the effective pressing weight range, it means that the quick-release head protective cover has fallen into the processing limit groove in the correct posture and there is no problem of skewness or jamming. Therefore, the protective cover placement signal is output.

[0090] Step S32: If the pressing weight of the current station does not fall within the effective pressing weight range, perform a station rotation operation to make the first station position fall into the preset protective cover pressing position, and perform a pressing operation.

[0091] The station rotation operation refers to the operation in which the machining rotating shaft 23 drives the machining limit groove that carries the quick-release head protective cover that has not been properly positioned to rotate counterclockwise, so that the station is transferred to the pressing operation area corresponding to the first pressing component 61.

[0092] The protective cover pressing position refers to the preset installation operation area of ​​the first pressing component 61, which corresponds to the position of the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 90°. It is specifically used for secondary pressing and correction of quick-release head protective covers that have not been properly positioned.

[0093] If the pressing weight at the current workstation does not fall within the effective pressing weight range, it means that the quick-release head protective cover has not fallen into the processing limit groove in the correct posture. The workstation needs to be transferred to the working area of ​​the first clamping component 61 to perform a secondary clamping and correction operation.

[0094] Step S33: After performing the clamping operation, obtain the current clamping weight at the workstation.

[0095] The current station clamping weight refers to the actual total weight borne by the bottom of the current processing limit groove collected by the pressure sensor after the first clamping component 61 completes the secondary clamping and correction operation. It is used to determine whether the quick-release head protective cover has returned to the normal position after the secondary clamping and correction.

[0096] Step S34: If the current pressing weight falls within the effective pressing weight range, output a protective cover placement signal.

[0097] If the current pressing weight falls within the effective pressing weight range, it means that after the second pressing correction of the first pressing component 61, the quick-release head protective cover has been adjusted to the correct posture and can output a protective cover placement signal.

[0098] This also includes a method for picking up the discarded quick-release head protective cover if the current pressing weight does not fall within the effective pressing weight range. This method includes: Step S340: If the current pressing weight does not fall within the effective pressing weight range, determine the abandoned station number.

[0099] The abandoned workstation number refers to the workstation number corresponding to the processing limit groove that supports the quick-release head protective cover that has not been properly positioned. It is used to locate the workstation position where waste needs to be cleaned up.

[0100] If the current pressing weight does not fall within the effective pressing weight range, it indicates that after the initial pressing and positioning operation, the quick-release head protective cover will not be damaged due to the small pressing force. Although the quick-release head protective cover that has not been properly positioned is corrected and limited by the quick-release head protective cover limit block, it still cannot be properly positioned. The pressing force of the first pressing component 61 is greater, and it continuously applies pressure to the skewed, stuck, or abnormally positioned quick-release head protective cover, which is very likely to cause such abnormally positioned quick-release head protective cover to be squeezed, deformed, cracked and damaged. Therefore, the quick-release head protective cover has lost the conditions for subsequent assembly and processing.

[0101] Step S341: Obtain the location of the abandoned quick-release head protective cover station corresponding to the abandoned station number in real time based on the abandoned station number.

[0102] The position of the discarded quick-release head protective cover station refers to the real-time position of the machining limit groove marked with the discarded station number as it rotates synchronously with the machining rotating disk 22.

[0103] Step S342: When the waste quick-release head protective cover station position falls into the preset waste disposal position, find the preset waste quick-release head protective cover picking parameters, and control the waste picking component 8 to perform the waste quick-release head protective cover picking operation according to the waste quick-release head protective cover picking parameters.

[0104] The waste disposal location refers to the fixed working area specifically used to remove unqualified protective covers and unqualified finished hubs. It corresponds to the position of the No. 1 processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 270°, which is the fixed installation working area of ​​the waste picking component 8.

[0105] The discarded quick-release head cover picking parameters refer to the set of parameters such as the robotic arm motion path, gripping force, and unloading position that are pre-stored by the system for picking up discarded quick-release head covers. These parameters are used to guide the waste picking component 8 to complete the picking and unloading operation of discarded parts.

[0106] The discarded quick-release head cover picking operation refers to the operation in which the waste picking component 8 picks up the discarded quick-release head cover with abnormal posture in the corresponding processing limit groove according to the discarded quick-release head cover picking parameters, removes it from the processing limit groove, transfers it to a special waste collection container for disposal, and then the waste picking component 8 is reset.

[0107] When the station position for discarded quick-release head protective covers falls into the waste disposal position, it means that the station bearing the damaged and unprocessable discarded quick-release head protective covers has rotated into the working range of the waste picking component 8, and the discarded quick-release head protective cover picking operation can be performed.

[0108] The methods for performing the quick-release head push-away operation include: Step S530: Obtain the abutment pressure corresponding to the discarded quick-release head limit block 213.

[0109] The contact pressure refers to the contact force value collected in real time by a pressure sensor fixedly installed on one side of the discarded quick-release head limit block 213 when the discarded quick-release head limit block 213 comes into contact with and is squeezed against the outer wall of a defective quick-release head that is abnormally oriented or misaligned. When the quick-release head falls normally into the machining limit groove, it will not come into contact with the discarded quick-release head limit block 213.

[0110] Step S531: If the contact pressure falls within the preset effective contact pressure range, output a rotation stop signal, search for the preset waste head pushing parameters, and control the waste pushing component 7 to perform the waste head pushing operation according to the waste head pushing parameters.

[0111] The effective contact pressure range refers to the pressure threshold range pre-calibrated by the system, which is used to determine whether the discarded quick-release head limit block 213 has reliably contacted the abnormal quick-release head, and to prevent the workpiece from shifting or failing to push away during the process.

[0112] When the contact pressure falls within the effective contact pressure range, it indicates that the discard quick-release head limit block 213 has come into contact with the unqualified quick-release head, and the unqualified quick-release head has reached the position where the discard push-away component can perform the discard push-away operation. The discard push-away component is located in the area of ​​the support disc 24 corresponding to the first processing limit groove 221 when the processing rotation shaft 23 rotates counterclockwise to 225°.

[0113] The discarded head push-away parameters refer to the extension and retraction stroke of the push-away rod 72, which is pre-recorded and stored in the system.

[0114] Step S532: After the discarded head removal and pushing operation is performed, determine the valid quick-release head protective cover station number, and obtain the valid quick-release head protective cover station position corresponding to the valid quick-release head protective cover station number in real time.

[0115] The valid quick-release head protective cover station number refers to the station number corresponding to the processing limit groove where the correct quick-release head protective cover has been placed, but the quick-release head could not be placed properly and has been pushed away from the waste disposal area. Only the correct quick-release head protective cover is retained in this processing limit groove, and the loading of the quick-release head protective cover can be skipped when it reaches the protective cover loading position later.

[0116] The effective quick-release head protective cover station position refers to the real-time position of the effective machining limit groove of the qualified quick-release head protective cover during the rotation of the machining rotating disk 22.

[0117] Step S533: When the effective quick-release head protective cover station position falls into the preset protective cover loading position, output a loading stop signal and output the effective quick-release head protective cover station position as the first station position to execute steps S2 to S7.

[0118] The protective cover loading position refers to the position corresponding to the No. 1 processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 0°. It is a dedicated station for the first transmission mechanism 12 to dock with the processing rotating disk 22, and is used to put the quick-release head protective cover into the empty processing limit groove.

[0119] The feeding stop signal is a control command issued by the control system to temporarily cut off or suspend the continuous feeding action of the first vibrating feeding device 1.

[0120] When the effective quick-release head protective cover position falls into the protective cover loading position, it means that the processing limit groove has rotated to the protective cover loading position, and only the intact and qualified quick-release head protective cover is left in the groove, so there is no need to put in a new protective cover.

[0121] The method for determining the current pressing and positioning component number based on the first workstation position and controlling the pressing and positioning component corresponding to the current pressing and positioning component number to perform the pressing operation includes: Step S20: If the first workstation position falls into the preset first pressing position, obtain the effective weight corresponding to the first effective workstation number.

[0122] The first pressing position refers to the preset fixed working angle area, which corresponds to the position of the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 45°. It is the exclusive pressing working area of ​​the first pressing positioning component 41.

[0123] Effective weight refers to the total weight carried in real time in the processing limit groove corresponding to the first effective work station number, which is collected in real time by the pressure sensor at the bottom of the groove.

[0124] Step S21: When the effective weight does not fall within the preset reliable effective weight range, output a material disengagement signal.

[0125] The reliable effective weight range refers to the weight range used to determine whether the processing limit groove is carrying any object. If the processing limit groove is not carrying any object, the effective weight will be less than the lower limit of the reliable effective weight range, and at this time, a material release signal will be output.

[0126] The material release signal refers to the signal that the quick-release head protective cover did not fall accurately into the processing limit groove when the first transmission mechanism 12 puts the quick-release head protective cover into the processing rotating disk 22.

[0127] When the effective weight does not fall within the reliable effective weight range, it indicates that the quick-release head protective cover was not successfully supported in the processing limit groove. During the feeding process, the quick-release head protective cover fell off and deviated, failing to fall into the processing limit groove.

[0128] Step S22: In response to the material release signal, output the first valid station number as the empty station number, and re-determine the first valid station number based on the rotation angle.

[0129] The empty position number refers to the position number corresponding to the machining limit groove on the machining rotating disk 22 that is not carrying any workpiece and is in an empty state. It is used to mark the empty positions that need to be replenished with materials, so as to facilitate the subsequent replenishment and placement of quick-release head protective covers.

[0130] Step S23: Obtain the rotation angle of the empty space corresponding to the empty space number in real time. When the rotation angle of the empty space reaches the preset circumferential rotation angle threshold, perform the protective cover loading operation.

[0131] The empty space rotation angle refers to the cumulative angle value that the machining limit groove marked with the empty space number has rotated counterclockwise from the initial position after leaving the protective cover loading position, as the machining rotating disk 22 rotates.

[0132] The circumferential rotation angle threshold refers to the preset angle threshold, specifically the total angle value that the processing limit groove marked with the empty position number needs to rotate one full counterclockwise with the processing rotating disk 22 to return to the material loading position of the protective cover.

[0133] When the rotation angle of the empty position reaches the threshold of the circumferential rotation angle, it means that the processing limit groove marked with the empty position number has rotated one revolution with the processing rotating disk 22 and returned to the protective cover loading position. The protective cover loading operation can be performed to replenish the quick-release head protective cover.

[0134] This also includes a method for performing a waste pickup operation when no successful compaction signal is present, the method comprising: Step S70: When there is no successful clamping signal, determine the clamping failure station number and the clamping failure station location corresponding to the clamping failure station number.

[0135] The "compression damage station number" refers to the station number marked when the pressure sensor detects that the total weight after compression does not fall within the acceptable weight range of the finished product.

[0136] The position of the clamping damage station refers to the real-time position of the machining limit groove marked with the clamping damage station number as it rotates synchronously with the machining rotating disk 22.

[0137] When there is no successful clamping signal, it means that the second clamping component 62 has performed the clamping operation. At this time, the quick-release head and quick-release head protective cover that failed to clamp have been damaged by clamping and need to be discarded as waste.

[0138] Step S71: When the damaged workstation position falls into the preset waste picking position, perform the waste picking operation.

[0139] The scrap pickup location refers to a fixed working area specifically for collecting failed-fitting finished hubs. It corresponds to the position of the first processing limit groove 221 when the processing rotating shaft 23 rotates counterclockwise to 270°, and is the fixed installation area for the scrap pickup component 8. The scrap pickup operation refers to the scrap pickup component 8 grabbing the failed-fitting finished hub from the processing limit groove according to preset scrap grabbing parameters, removing it, and transferring it to the scrap collection container for disposal. Afterward, the scrap pickup component 8 returns to its initial working position, awaiting the next scrap grabbing task. When the damaged pressing station falls into the scrap pickup location, it indicates that the failed-fitting finished hub has rotated into the working range of the scrap pickup component 8, and the scrap pickup operation can be performed directly. The scrap grabbing parameters refer to the robotic arm's motion path and grabbing force preset by the system for grabbing failed-fitting finished hubs.
