Description

Technical Field

[0001] This invention relates to the field of valve stem seal processing technology, and in particular to an automatic spring loading machine. Background Technology

[0002] Valve stem seals are a crucial component of the engine valve assembly. They prevent engine oil from entering the exhaust pipe, thus avoiding oil loss, preventing leakage of the gasoline-air mixture and exhaust gases, and preventing engine oil from entering the combustion chamber. Because valve stem seals come into contact with gasoline and engine oil at high temperatures during operation, they require materials with excellent heat and oil resistance, typically fluororubber.

[0003] Existing valve stem seal structures, such as Figure 1 As shown, it includes a rubber sleeve, an outer skeleton sleeve, and a spring connected coaxially. The rubber sleeve is made of fluororubber, the outer skeleton sleeve is an outer frame that is vulcanized together with the rubber sleeve, and the spring is an annular spring energy storage ring. The end of the rubber sleeve away from the outer skeleton sleeve is provided with a mounting groove for inserting the spring to achieve a seal on the engine valve guide rod.

[0004] Due to the properties of rubber, the rubber sleeve and outer sheath form a structure similar to... during the vulcanization process. Figure 1 (A) shows that the end of the rubber sleeve away from the outer shell is usually integrally formed with a convex column-shaped excess material structure. Therefore, when making valve oil seals, the convex column-shaped excess material at the end of the rubber sleeve is usually cut off manually before the spring is installed. This not only increases the burden on workers and labor costs, but also has a high error rate, makes it easy for unqualified products to be mixed in, and has low production efficiency.

[0005] Therefore, it is necessary to provide an automatic spring loading machine. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects in the prior art and provide an automatic spring loading machine that reduces the burden on workers, lowers labor costs, ensures product qualification rate, and improves production efficiency.

[0007] To achieve the above-mentioned technical effects, the technical solution of the present invention is: an automatic spring loading machine, comprising:

[0008] A processing table, wherein the processing table is horizontally arranged and a positioning seat is provided on its top surface;

[0009] The processing assembly includes a feeding assembly, a cutting assembly, a spring loading assembly, and an unloading assembly distributed circumferentially along the processing table;

[0010] A rotating assembly drives the processing table to rotate intermittently and periodically, causing the positioning seat to rotate sequentially to the corresponding positions of each processing assembly, so as to sequentially perform the cyclical operation of fitting the workpiece into the top of the positioning seat, cutting off the excess material of the workpiece, inserting a spring into the outer edge of the workpiece, and removing the workpiece from the positioning seat.

[0011] Preferably, in order to improve processing efficiency, multiple positioning seats are provided, and each one corresponds to a processing component.

[0012] Preferably, in order to ensure that after the processing table rotates, each positioning seat rotates to the corresponding processing position of each processing component, so that multiple processing components can simultaneously perform corresponding processing operations on their respective positioning seats and the workpieces on the positioning seats, thereby improving processing efficiency, the positioning seats are evenly distributed along the circumference of the processing table.

[0013] Preferably, in order to facilitate the cutting of excess material on the rubber sleeve of the workpiece, the positioning seat rotates around its own axis on the processing table. A driving component is provided on one side of the processing table. After the positioning seat rotates to the position corresponding to the cutting component, the driving component drives the positioning seat to rotate around its own axis.

[0014] Preferably, in order to enable the driving component to drive the positioning seat and the workpiece on the positioning seat to rotate after the positioning seat rotates to the position corresponding to the cutting component, so as to facilitate the cutting of the workpiece residue, the driving component includes a driving wheel for abutting against the outer edge of the positioning seat and a driving motor for driving the driving wheel to rotate around its own axis.

[0015] Preferably, in order to cut the workpiece scrap, the cutting assembly includes a cutter and a propulsion unit for driving the cutter to move.

[0016] Preferably, in order to facilitate the collection of scrap material cut from the workpiece and avoid the accumulation of scrap material on the processing table, which would affect the processing environment, the cutting assembly further includes a scrap bin and a blower pipe located above the processing table and facing the scrap bin. The corresponding position of the cutting assembly is located between the blower pipe and the scrap bin, and the blower pipe is used to input air to blow the scrap material cut from the workpiece by the cutting assembly into the scrap bin.

[0017] Preferably, in order to prevent the workpiece from shifting or sliding up and down during the cutting of scrap material, the positioning seat is provided with a negative pressure through hole extending along its own height direction, and a negative pressure cover for extracting air is provided directly below the corresponding position of the cutting component, so that the workpiece is firmly adsorbed on the positioning seat when the positioning seat rotates to the corresponding position of the cutting component.

[0018] Preferably, in order to enhance the negative pressure suction effect, the negative pressure cover is connected to a distance reduction component, which is used to reduce the distance between the negative pressure cover and the corresponding position of the cutting component.

[0019] Preferably, in order to facilitate the placement of the workpiece to be cut and spring-loaded onto the positioning seat, the feeding assembly includes a feeding groove, a feeding moving mechanism, and a feeding clamp. The feeding groove is upwardly oriented, with a groove width consistent with the outer diameter of the valve oil seal and a groove depth less than the height of the valve oil seal. The feeding moving mechanism drives the feeding clamp to move, thereby clamping the workpieces in the feeding groove one by one and placing them onto the top of the positioning seat.

[0020] Preferably, in order to ensure the cutting effect of the leftover material and to prevent the workpiece from falling off the positioning seat during the rotation of the processing table, the processing component further includes a clamping component disposed between the feeding component and the cutting component. The clamping component includes a pressure plate and a clamping lifting unit that drives the pressure plate to move up and down to press the workpiece onto the positioning seat.

[0021] Preferably, in order to install the spring onto the workpiece, the spring mounting assembly includes a spring mounting rod, a spring mounting moving assembly, a pressing assembly, and a spring supply groove. The spring mounting rod is vertically arranged, with the outer diameter of its bottom end between the inner and outer diameters of the spring. An annular groove for engaging the spring is provided immediately adjacent to its bottom end. The spring mounting moving assembly drives the spring mounting rod to move so that the spring is engaged in the annular groove above the spring supply groove and then moves to a position directly above the positioning seat. The pressing assembly then presses the spring engaged in the annular groove down to the circumferential outer edge of the workpiece.

[0022] Preferably, in order to facilitate pressing down the spring that is locked in the annular groove until it is pressed into the mounting groove of the workpiece rubber sleeve, the pressing assembly includes a pressure sleeve that is slidably sleeved outside the spring rod and a telescopic unit that drives the pressure sleeve to move.

[0023] Preferably, in order to detect whether the positioning seat has rotated smoothly to the position corresponding to the spring mounting assembly and whether a spring has been installed on the workpiece, the processing assembly further includes a detection assembly. The detection assembly is used to detect whether the positioning seat has rotated to the position corresponding to the spring mounting assembly and whether a spring has been installed on the positioning seat that has turned to the position corresponding to the material picking assembly.

[0024] Preferably, in order to achieve the detection function, the detection position includes two distance sensors, and the two distance sensors are respectively oriented toward the spring mounting position on the workpiece surface corresponding to their respective test positions.

[0025] Preferably, in order to classify the processed products according to the test results, reduce the workload of workers, and avoid the mixing of defective products with qualified products, the unloading component is a sorting component for screening and collecting workpieces according to whether they are qualified. The sorting component includes a finished product box, a waste product box, a sorting moving component, and a sorting clamp. The sorting moving component drives the sorting clamp to move so as to clamp the workpieces on the positioning seat, put qualified workpieces with springs into the finished product box, and put workpieces without springs into the waste product box.

[0026] In summary, compared with the prior art, the automatic spring-loading machine of the present invention drives the worktable to rotate through a rotating component, so that the positioning seat rotates sequentially to the corresponding positions of the feeding component, cutting component, spring-loading component and unloading component in a cyclical operation. This facilitates the cutting of excess material and the installation of springs after the workpiece is installed on the positioning seat, and then the workpiece with springs is removed, realizing the automatic processing of valve oil seals. This reduces the workload of workers, lowers labor costs and significantly improves production efficiency. Attached Figure Description

Detailed Implementation

[0050] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0051] like Figures 1-6 As shown in (C), the automatic spring loading machine of the present invention is mainly used to cut the excess material at the end of the rubber sleeve 1110 in the vulcanized workpiece 1100, and then to load the spring 1130 into the mounting groove 1111 of the rubber sleeve 1110. The specific structure includes:

[0052] The processing table 1000 is horizontally set and has a positioning seat 2000 on its top surface;

[0053] The processing assembly includes a feeding assembly 3000, a cutting assembly 4000, a spring loading assembly 5000, and an unloading assembly 6000 distributed circumferentially along the processing table 1000.

[0054] The rotating component 7000 drives the processing table 1000 to rotate intermittently and periodically, causing the positioning seat 2000 to rotate sequentially to the corresponding positions of each processing component, so as to perform the cyclical operation of fitting the workpiece 1100 onto the top of the positioning seat 2000, cutting off the excess material of the workpiece 1100, installing the spring 1130 on the circumferential outer edge of the workpiece 1100, and removing the workpiece 1100 from the positioning seat 2000.

[0055] Specifically, such as Figure 2-Figure 2 As shown in (B), the automatic spring loading machine of the present invention includes a base 1400, and a horizontal processing table 1000 is arranged directly above the base 1400. The processing table 1000 is disc-shaped and coaxial with the base 1400.

[0056] The processing table 1000 is provided with positioning seats 2000 arranged in an equally spaced ring array. The top of the positioning seats 2000 is located above the processing table 1000 and is used to fit the workpiece 1100, so as to facilitate the processing of the workpiece 1100.

[0057] The processing components include a feeding component 3000, a clamping component 8000, a cutting component 4000, a spring mounting component 5000, a detection component 9000, and an unloading component 6000 distributed circumferentially along the processing table 1000. The feeding component 3000, the clamping component 8000, the cutting component 4000, the spring mounting component 5000, the detection component 9000, and the unloading component 6000 correspond one-to-one with the six positioning seats 2000 on the processing table 1000.

[0058] A rotating assembly 7000 is provided between the base 1400 and the processing table 1000. The rotating assembly 7000 drives the processing table 1000 to rotate intermittently and periodically around its own axis, so that each positioning seat 2000 can pass through the positions corresponding to the clamping assembly 8000, the cutting assembly 4000, the spring mounting assembly 5000, the detection assembly 9000 and the unloading assembly 6000 in sequence, and rotate in a fixed direction in a cyclical manner as described above.

[0059] In this embodiment, the rotating component 7000 drives the processing table 1000 to rotate 60° each time. This allows the positioning seat 2000 to rotate from the position corresponding to one processing step to the position corresponding to the next processing step after one rotation. For example, it can rotate from the position corresponding to the initial feeding component 3000 to the position corresponding to the clamping component 8000, while the adjacent position initially corresponding to the clamping component 8000 rotates to the position corresponding to the cutting component 4000. Similarly, it rotates from the position initially corresponding to the unloading component 6000 to the position corresponding to the feeding component 3000. The rotating component 7000 controls the processing table 1000 to rotate six times, completing one full rotation. This allows the workpiece 1100 on the positioning seat 2000 to complete the entire processing operation. This allows different processing components to perform different processing operations simultaneously, reducing the workload of workers, lowering labor costs, and improving processing efficiency.

[0060] Specifically, among the six processing components mentioned above, the feeding component 3000 is used to clamp the workpiece 1100 to be processed and then place the workpiece 1100 on the top of its corresponding positioning seat 2000 for convenient installation; the clamping component 8000 is used to press the assembled workpiece 1100 downwards onto the positioning seat 2000 to prevent the workpiece 1100 from shifting or sliding up and down during processing and as it rotates with the processing table 1000, thus affecting the processing quality. This helps to ensure the processing quality of the valve oil seal products and improve the product qualification rate; the cutting component 4000 is used to remove the excess material from the end of the workpiece 1100 on the positioning seat 2000; and the spring mounting component 5000 is used to install the spring 1130 into the mounting groove 1111 of the rubber sleeve 1110 of the workpiece 1100, completing the main assembly operation of the valve oil seal components and forming the product. The detection component 9000 has two main functions: first, to determine whether one of the six positioning seats 2000 has rotated to the position corresponding to the spring mounting component 5000, so that after the positioning seat 2000 rotates to the target position, the spring mounting component 5000 can perform the corresponding spring mounting operation on the workpiece 1100 on the positioning seat 2000; second, to determine whether the spring 1130 has been successfully installed into the mounting groove 1111 of the rubber sleeve 1110 of the workpiece 1100, that is, to determine whether the parts have been successfully assembled and whether the product is qualified. The unloading component 6000 is a sorting component. Based on the detection structure of the detection component 9000, it determines whether the product workpiece 1100 is qualified. Based on the product detection results, the product workpiece 1100 is removed from the positioning seat 2000 and sorted and classified to distinguish between qualified products and defective products.

[0061] Therefore, by adopting the above-mentioned structural method, the automated loading, pressing, cutting, spring mounting, inspection, and sorting operations replace manual processing, which not only reduces the burden on workers and lowers labor costs, but also significantly improves the processing efficiency of valve oil seals. Furthermore, by screening through inspection, defective products are distinguished from qualified products, thereby preventing unqualified products from being mixed into the final products and ensuring the qualification rate of the final products.

[0062] To drive the machining table 1000 to rotate in a fixed direction, periodically, and intermittently, the specific structure of the rotating assembly 7000 is as follows: Figure 3 (A) and such Figure 3As shown in (B), the rotary motor 7010 is fixed on the base 1400. The output end of the rotary motor 7010 is coaxially connected to the drive wheel 7020. The drive wheel 7020 is connected to the driven wheel 7040 via a synchronous belt 7030. The machining table 1000 is coaxially connected to the bottom of the machining table 1000. The shaft 1020 is coaxially connected to the driven wheel 7040. The base 1400 is also provided with a second bearing 1470. The outer ring of the second bearing 1470 is fixedly connected to the base 1400, and the inner ring is fixedly connected to the shaft 1020 to support the machining table 1000 to rotate around its own axis.

[0063] After the rotary motor 7010 is started, it drives the drive wheel 7020 to rotate. The drive wheel 7020 acts on the driven wheel 7040 through the synchronous belt 7030, causing the driven wheel 7040 to rotate. In turn, it can drive the machining table 1000 to rotate around its own axis through the rotating shaft 1020, changing the position of each positioning seat 2000, so as to facilitate the corresponding processing of the workpiece 1100 on the positioning seat 2000.

[0064] The top surface of the base 1400 is also fixed with six supports distributed along its circumference. The six supports are the first support 1410, the second support 1420, the third support 1430, the fourth support 1440, the fifth support 1450 and the sixth support 1460, which are connected to the six processing components to support the feeding component 3000, the clamping component 8000, the cutting component 4000, the spring mounting component 5000, the detection component 9000 and the unloading component 6000.

[0065] The feeding assembly 3000 is used to place the workpiece 1100 onto the positioning seat 2000 on the processing table 1000, where the workpiece 1100 is not yet in place. This facilitates subsequent operations such as cutting excess material, installing springs, inspection, and sorting of the workpiece 1100. The specific structure of the feeding assembly 3000 is as follows: Figure 3-Figure 3 As shown in (D), the feeding assembly 3000 includes a feeding groove 3010, a feeding moving mechanism 3020, and a feeding clamp 3030. The feeding groove 3010 is set upward, the groove width is consistent with the outer diameter of the valve oil seal, and the groove depth is less than the height of the valve oil seal. The feeding moving mechanism 3020 drives the feeding clamp 3030 to move, so as to clamp the workpieces 1100 in the feeding groove 3010 one by one and put them on the top of the positioning seat 2000.

[0066] More specifically, the feeding trough 3010 is fixedly connected to the base 1400 via the first bracket 1410. The feeding trough 3010 includes an inclined section 3011 and a horizontal section 3012 connected sequentially along its length. The horizontal section 3012 is adjacent to the input end of the feeding trough 3010 and is horizontally arranged. The inclined section 3011 is adjacent to the output end of the feeding trough 3010 and is inclined. The end of the inclined section 3011 adjacent to the horizontal section 3012 is lower than the other end of the inclined section 3011. An upward positioning baffle 3013 is provided at the end of the horizontal section 3012 away from the inclined section 3011. A notch is provided at the end of the horizontal section 3012 adjacent to the positioning baffle 3013, so that the groove depth at the end of the horizontal section 3012 is less than that at other positions of the feeding trough 3010. The positioning baffle 3013 is located between the axis of the processing table 1000 and the horizontal section 3012.

[0067] The end of the inclined section 3011 furthest from the horizontal section 3012, which is also the input end of the feeding trough 3010, allows for manual addition of the workpiece 1100 to be processed into the feeding trough 3010. It can also be used to connect to the output end of a vibratory feeder. Various types of vibratory feeders can be selected, such as those produced or sold by Suzhou Hengwangyou Automation Equipment Co., Ltd. and Kunshan Yiheda Intelligent Technology Co., Ltd., all of which can automatically feed the workpiece 1100 to the feeding trough 3010, thereby reducing the workload of workers and lowering labor costs. The feeding clamp 3030 preferably uses a pneumatic clamp, and multiple types can be selected, such as the MHZ2 and MHZL2 series Andatong pneumatic finger cylinders.

[0068] After the workpiece 1100 is fed into the feeding trough 3010, due to the design of the inclined section 3011, the workpiece 1100 in the feeding trough 3010 will automatically slide down, pushing the workpiece 1100 in front, so that the first workpiece 1100 abuts against the positioning baffle 3013. Due to the notch design on the horizontal section 3012 of the positioning baffle 3013, its groove depth is reduced, which makes it convenient for the two clamping arms of the feeding clamp 3030 to move to both sides of the notch in the feeding trough 3010 to clamp the workpiece 1100 at the notch, that is, abutting against the positioning baffle 3013. After the feeding clamp 3030 clamps the workpiece 1100 corresponding to the notch and drives the workpiece 1100 to leave the feeding trough 3010, the workpieces 1100 in other positions in the feeding trough 3010 move forward, so that the workpieces 1100 at the end abut against the positioning baffle 3013.

[0069] The feeding movement mechanism 3020 includes a first feeding cylinder 3021 and a second feeding cylinder 3022. The axial direction of the first feeding cylinder 3021 is parallel to the horizontal section 3012, and the axial direction of the second feeding cylinder 3022 is parallel to the vertical direction. The feeding trough 3010 is fixedly connected to a first feeding frame 3023 via a first connecting frame 3028. The first feeding frame 3023 has an integrally formed first feeding guide rail 3024 extending parallel to the horizontal section 3012. The cylinder barrel of the first feeding cylinder 3021 is fixed to the first feeding frame 3022. On 23, the piston rod is fixedly connected to the second feeding frame 3025, the second feeding frame 3025 is slidably engaged with the first feeding guide rail 3024, the second feeding frame 3025 is provided with a second feeding guide rail 3026 extending in the vertical direction, the cylinder of the second feeding cylinder 3022 is fixedly fixed on the second feeding frame 3025, the piston rod is fixedly connected to the third feeding frame 3027, the third feeding frame 3027 is slidably engaged with the second feeding guide rail 3026, and is fixedly connected to the feeding clamp 3030 through the second connecting frame 3029.

[0070] In the above structure, the feeding trough 3010 and the first feeding frame 3023 are kept relatively fixed by the first connecting frame 3028. The first feeding cylinder 3021 is started, and its piston rod drives the second feeding frame 3025, the second feeding cylinder 3022 and the feeding clamp 3030 to move horizontally. The second feeding cylinder 3022 is started, and its piston rod drives the third feeding frame 3027 and the feeding clamp 3030 to move up and down.

[0071] When the feeding assembly 3000 is running, the first feeding cylinder 3021 first adjusts the horizontal position of the feeding clamp 3030, moving it directly above the output end of the feeding trough 3010. Then, the second feeding cylinder 3022 drives the feeding clamp 3030 downward, clamping the workpiece 1100 at the end of the feeding trough 3010. Afterward, the second feeding cylinder 3022 drives the feeding clamp 3030 upward, and then the first feeding cylinder 3021 drives the second feeding cylinder 3022 and the feeding clamp 3030 forward to the positioning seat 2000. Directly above, the second feeding cylinder 3022 drives the feeding clamp 3030 to move downward, so that the clamped workpiece 1100 is placed on the top of the positioning seat 2000. After the feeding clamp 3030 releases the workpiece 1100, the second feeding cylinder 3022 drives the feeding clamp 3030 to move upward. The first feeding cylinder 3021 adjusts the horizontal position of the feeding clamp 3030, so that the feeding clamp 3030 moves directly above the output end of the feeding groove 3010. In this way, the workpieces 1100 in the feeding groove 3010 are transported one by one to the positioning seats 2000 on the processing table 1000.

[0072] After the feeding assembly 3000 loads the workpiece 1100 onto the positioning seat 2000, the rotating assembly 7000 drives the processing table 1000 to rotate 60°, so that the positioning seat 2000, which just loaded the workpiece 1100, rotates to the position corresponding to the clamping assembly 8000. Specifically, the clamping assembly 8000 includes a pressure plate 8010 and a clamping lifting unit 8020 that drives the pressure plate 8010 to move up and down to clamp the workpiece 1100 onto the positioning seat 2000. The clamping lifting unit 8020 is a clamping cylinder, which is set vertically downward. The cylinder barrel of the clamping cylinder is fixedly connected to the second bracket 1420, and the piston rod is downward and fixedly connected to the top surface of the pressure plate 8010.

[0073] With the above structure, when the processing table 1000 rotates the positioning seat 2000, which holds the workpiece 1100, to directly below the pressure plate 8010, the clamping lifting unit 8020 activates, causing the pressure plate 8010 to move downwards and then upwards back to its original position. The pressure plate 8010 presses the workpiece 1100 firmly onto the positioning seat 2000, strengthening the connection between the two and preventing the workpiece 1100 from swaying or shifting during the rotation of the positioning seat 2000 with the processing table 1000 and during subsequent processing. Therefore, by pressing the workpiece 1100 firmly onto the positioning seat 2000 using the clamping assembly 8000, the relative position of the workpiece 1100 and the positioning seat 2000 remains fixed, which helps ensure the processing quality of the workpiece 1100 and improves the product qualification rate.

[0074] After the workpiece 1100 is clamped, the workpiece 1100 can be cut to remove the excess material on the rubber sleeve 1110 of the workpiece 1100. A further improvement is that the positioning seat 2000 rotates around its own axis on the processing table 1000. A drive assembly 4050 is provided on one side of the processing table 1000. After the positioning seat 2000 rotates to the position corresponding to the cutting assembly 4000, the drive assembly 4050 drives the positioning seat 2000 to rotate around its own axis.

[0075] With the above structure, when removing the excess material from workpiece 1100, it is only necessary to keep the cutting position of the cutting component 4000 unchanged. The driving component 4050 drives the positioning seat 2000 to rotate around its own axis, thereby driving the workpiece 1100 on the rear positioning seat 2000 to rotate. After the workpiece 1100 and the cutting component 4000 maintain relative rotation, the excess material of workpiece 1100 can be cut by the cutting component 4000.

[0076] To facilitate the rotation of the positioning seat 2000 around its own axis, six connecting holes 1001 are arranged in a ring array on the processing table 1000, corresponding one-to-one with the six positioning seats 2000. A first bearing 1010 is installed in the connecting hole 1001, and the positioning seat 2000 passes through the first bearing 1010. The outer ring of the first bearing 1010 is fixedly connected to the circumferential inner wall of the connecting hole 1001, and the inner ring of the first bearing 1010 is fixedly connected to the positioning seat 2000. In this way, the positioning seat 2000 can rotate around its own axis under the support of the first bearing 1010.

[0077] The drive assembly 4050 includes a drive wheel 4052 for abutting against the circumferential outer edge of the positioning seat 2000 and a drive motor 4051 for driving the drive wheel 4052 to rotate about its own axis.

[0078] Specifically, the drive motor 4051 is fixed above the base 1400, and its output end is fixedly connected to the drive wheel 4052 along the same axis. To ensure a good transmission connection between the drive wheel 4052 and the positioning seat 2000, the portion of the positioning seat 2000 located below the processing table 1000 is provided with an annular groove 2002 coaxial with itself. Figure 3 As shown in (A), an elastic sleeve 2010 is fixed to the circumferential inner wall of the annular groove 2002. The elastic sleeve 2010 is preferably made of an elastic material, such as rubber, silicone or latex. When the processing table 1000 drives the positioning seat 2000 to rotate to the position corresponding to the cutting component 4000, the outer circumferential edge of the elastic sleeve 2010 at the bottom of the positioning seat 2000 abuts against the wheel surface of the drive wheel 4052. In this state, the drive motor 4051 drives the drive wheel 4052 to rotate. The drive wheel 4052 acts on the elastic sleeve 2010 through friction, so that the elastic sleeve 2010 and the positioning seat 2000 can rotate around their own axis, thereby driving the workpiece 1100 on the positioning seat 2000 to rotate, so that the cutting component 4000 can cut the excess material of the rubber sleeve 1110 on the workpiece 1100.

[0079] To achieve the cutting of excess material on workpiece 1100, the cutting assembly 4000 of this invention includes a cutter 4010 and a propulsion unit 4020 for driving the cutter 4010 to move. During cutting, the propulsion unit 4020 controls the movement of the cutter 4010, so that after the blade of the cutter 4010 moves to the excess material on the rubber sleeve 1100, the position of the cutter 4010 remains fixed. At the same time, the driving assembly 4050 drives the positioning seat 2000 and the workpiece 1100 to rotate, so that the excess material on the rubber sleeve 1110 can be smoothly cut off. Then, the propulsion unit 4020 drives the cutter 4010 to retract, so that the workpiece 1100 with the excess material cut off on the positioning seat 2000 can be spring-loaded.

[0080] Specifically, such as Figure 4-Figure 4As shown in (C), the cutting assembly 4000 includes a cutting frame 4091, which is fixedly connected to the base 1400 via a third bracket 1430. A directional motor 4090 is fixedly mounted on the cutting frame 4091. The output shaft of the directional motor 4090 passes through the cutting frame 4091 and is fixedly connected to a directional disc 4092 at its end. A directional groove is provided on the side of the directional disc 4092 away from the directional motor 4090. A directional plate 4093 is fixedly connected in the groove. A propulsion unit 4020 is located on the side of the directional plate 4093 away from the directional motor 4090.

[0081] With the above structure, the position of the directional motor 4090 is fixed by the cutting frame 4091. When the directional motor 4090 rotates, it can drive the directional disc 4092 and the directional plate 4093 to rotate, thereby changing the position of the cutting blade 4010 relative to the horizontal plane, thus adjusting the cutting position of the workpiece 1100 on the positioning seat 2000, improving the cutting quality, and thus improving the product quality.

[0082] The propulsion unit 4020 includes a cutting propulsion cylinder 4021. The cylinder barrel of the cutting propulsion cylinder 4021 is fixed on the directional plate 4093. One end of the piston rod is fixedly connected to the connecting rod 4022. The other end of the connecting rod 4022 is sleeved on the first propulsion screw 4025. The length direction of the connecting rod 4022 is perpendicular to the axis of the cutting propulsion cylinder 4021. The axis of the cutting propulsion cylinder 4021 is parallel to the axis of the first propulsion screw 4025. The first propulsion screw 4025 is threaded with cutting nuts 4023 located on both sides of the connecting rod 4022. The connecting rod 4022 is sandwiched between the two cutting nuts 4023. The first propulsion screw 4025 is coaxially fixedly connected to the first propulsion slide rod 4024. The directional plate 4093 is fixedly fixed with the first propulsion slide sleeve 4026. The first propulsion slide rod 4024 and the first propulsion slide sleeve 4026 are slidably engaged and fixedly connected to the cutter 4010.

[0083] With the above structure, the piston rod of the cutting and pushing cylinder 4021 moves telescopically, causing the connecting rod 4022 to drive the first pushing screw 4025 and the first pushing slide 4024 to move smoothly along the length of the first pushing slide sleeve 4026, thereby driving the cutter 4010 to move and adjust its position. Since the end of the connecting rod 4022 is sleeved on the first pushing screw 4025, the connecting rod 4022 is clamped by two cutting nuts 4023 threaded to the first pushing screw 4025. This allows for easy adjustment of the axial position of the connecting rod 4022 relative to the first pushing screw 4025 by adjusting the axial position of the two cutting nuts 4023 on the first pushing screw 4025, thereby fine-tuning the moving position of the cutter 4010. This adjusts the cutting depth of the cutter 4010 on the workpiece 1100 on the positioning seat 2000, preventing the cutting depth from being too small or too large, which would prevent the entire piece of material from being cut.

[0084] To facilitate the detection of whether the piston rod of the cutting propulsion cylinder 4021 has driven the cutter 4010 to move to the target position to cut the workpiece 1100+, a positioning detection unit is also provided on the directional plate 4093. The positioning detection unit is coaxial with the cutting propulsion cylinder 4021 and adjacent to its piston rod. Specifically, the positioning detection unit includes a second propulsion sleeve 4081 fixed on the directional plate 4093. A second propulsion slide rod 4080 is slidably connected to the second propulsion sleeve 4081. Both ends of the second propulsion slide rod 4080 are fixed with propulsion protrusions 4084. A propulsion base plate 4085 is fixed to the end of the second propulsion sleeve 4081 away from the cutting propulsion cylinder 4021. The propulsion base plate 4085 and the second propulsion slide rod 4080 are connected by a propulsion compression spring 4082. A positioning sensor 4083 is provided at the end of the propulsion base plate 4085 adjacent to the second propulsion slide rod 4083. The positioning sensor 4083 is a displacement sensor.

[0085] With the above structure, when the piston rod of the cutting propulsion cylinder 4021 moves forward, it contacts the propulsion protrusion 4084 at one end of the second propulsion slide rod 4080, pushing the second propulsion slide rod 4080 to contact the second propulsion sleeve 4081, compressing the propulsion spring 4082. The position of the second propulsion slide rod 4080 is detected by the position sensor 4083, thus facilitating the determination of whether the cutting propulsion cylinder 4021 has reached the target position. After cutting is completed, during the process of the piston rod of the cutting propulsion cylinder 4021 retracting to its original position, the propulsion spring 4082 acts on the propulsion protrusion 4084, causing the second propulsion slide rod 4080 to move towards the cutting propulsion cylinder 4021 to return to its initial position, maintaining a certain distance from the piston rod of the cutting propulsion cylinder 4021. Figure 4 As shown in (B).

[0086] After the scrap material is cut, rubber scrap remains on the surface of the processing table 1000, affecting the cleanliness of the environment around the processing table 1000. To address this, the cutting assembly 4000 also includes a waste bin 4030 and a blow pipe 4040 located above the processing table 1000 and facing the waste bin 4030. The corresponding position of the cutting assembly 4000 is located between the blow pipe 4040 and the waste bin 4030, and the blow pipe 4040 is used to input air to blow the scrap material cut by the cutting assembly 4000 from the workpiece 1100 into the waste bin 4030.

[0087] like Figure 4 and Figure 4 As shown in (A), a waste bin 4030 with an open top is also provided on the base 1400. The waste bin 4030 is located on the side and below the processing table 1000. A waste guide groove 4031 is provided between the waste bin 4030 and the processing table 1000. The opening of the waste guide groove 4031 is upward and inclined downward. The bottom of the higher end of the waste guide groove 4031 is flush with the processing table 1000 and sealed. The lower end extends downward into the upper part of the waste bin 4030. Two blowing pipes 4040 are provided, facing the waste bin 4030. The blowing pipes 4040 are located between the planes of the two inner side walls of the waste guide groove 4031.

[0088] A negative pressure pump 4060 is fixed on the cutting frame 4091. The output end of the negative pressure pump 4060 is connected to a negative pressure pipe 4061. The negative pressure pipe 4061 is fixedly connected to the cutting frame 4091. The end of the negative pressure pipe 4061 away from the negative pressure pump 4060 is connected to a negative pressure housing 4062 with a bottom opening. The bottom of the negative pressure housing 4062 is fixedly covered by a negative pressure housing cover 4063. The negative pressure housing 4062 and the negative pressure housing cover 4063 enclose a negative pressure cavity, which is connected between the blowing pipe 4040 and the negative pressure pipe 4061.

[0089] While the workpiece 1100 is cutting the excess material, the negative pressure pump 4060 is started, and gas is delivered to the negative pressure chamber formed by the negative pressure housing 4062 and the negative pressure housing cover 4063 through the negative pressure pipe 4061. At the same time, the gas is ejected through the blowing pipe 4040, which blows the excess material cut by the cutter 4010 from the rubber sleeve 1110 to the outside of the processing table 1000. The excess material enters the inclined downward waste guide groove 4031. Under the guidance of the waste guide groove 4031, the cut excess material, i.e., the waste, falls into the waste bin 4030, thereby realizing the automatic collection of the cut waste and avoiding the accumulation of the waste on the processing table 1000 or being thrown out with the rotation of the processing table 1000, which would affect the surrounding processing environment.

[0090] During the cutting process, the cutter 4010 contacts the workpiece 1100, and the workpiece 1100 rotates with the positioning seat 2000. The workpiece 1100 is prone to shifting and shaking, affecting the cutting quality. Therefore, the positioning seat 2000 is provided with a negative pressure through hole 2001 extending along its own height direction. A negative pressure cover for extracting air is provided directly below the corresponding position of the cutting component 4000, so that when the positioning seat 2000 rotates to the corresponding position of the cutting component 4000, the workpiece 1100 is firmly adsorbed on the positioning seat 2000. The negative pressure cover is connected to a distance reduction component, which is used to reduce the distance between the negative pressure cover and the corresponding position of the cutting component 4000. The negative pressure cover is used to connect a negative pressure device.

[0091] Specifically, the pitch reduction assembly is a pitch reduction cylinder, whose cylinder barrel is fixed above the base 1400, the piston rod extends vertically, and an upward-facing negative pressure cover is fixedly connected to its top end. The negative pressure cover is located directly below the machining table 1000. Figure 4 As shown in (A).

[0092] When the positioning seat 2000 rotates with the processing table 1000 to the position corresponding to the cutting component 4000, the negative pressure cover faces the negative pressure through hole 2001 on the positioning seat 2000. The distance reduction cylinder is activated to reduce the distance between it and the positioning seat 2000. Then the negative pressure device is activated to extract the air pressure in the negative pressure cover, so that the air in the negative pressure through hole 2001 is drawn out, and a negative pressure is formed in the negative pressure through hole 2001, which firmly adsorbs the workpiece 1100 onto the positioning seat 2000, preventing the workpiece 1100 from shaking or shifting up and down during the cutting process, thereby affecting the processing quality.

[0093] The negative pressure device can preferably be a negative pressure pump 4060. After the negative pressure pump 4060 is started, it draws the air in the negative pressure through hole 2001 and the air between the positioning seat 2000 and the negative pressure cover. The air is then transported to the negative pressure housing 4062 through the negative pressure pipe 4061 and sprayed out from the blowing pipe 4040. On the one hand, this can ensure a stable connection between the positioning seat 2000 and the workpiece 1100 during the cutting process and ensure the cutting quality. On the other hand, the drawn air can blow the cut waste into the waste box 4030, which is beneficial to the cleanliness of the processing table 1000 and the surrounding environment.

[0094] After the excess material of workpiece 1100 is cut off, the top surface of workpiece 1100 is flat. Spring 1130 needs to be installed in the mounting groove 1111 on the outer edge of the rubber sleeve 1110 of workpiece 1100. At this time, the rotating component 7000 drives the processing table 1000 to rotate 60°, so that the workpiece 1100 on the positioning seat 2000 after the excess material is cut off rotates to the position corresponding to the spring mounting component 5000, so as to facilitate the spring mounting operation on workpiece 1100.

[0095] A further improvement is that the spring mounting assembly 5000 includes a spring mounting rod 5010, a spring mounting moving assembly 5020, a pressing assembly 5030, and a spring supply groove 5040. The spring mounting rod 5010 is vertically arranged, and the outer diameter of its bottom end is between the inner and outer diameters of the spring 1130. An annular groove 5011 for engaging the spring 1130 is provided at its bottom end. The spring mounting moving assembly 5020 drives the spring mounting rod 5010 to move so that the spring 1130 is engaged in the annular groove 5011 above the spring supply groove 5040, and then moves to be directly above the positioning seat 2000. The pressing assembly 5030 then presses the spring 1130 engaged in the annular groove 5011 down to the circumferential outer edge of the workpiece 1100. The pressing assembly 5030 includes a pressure sleeve 5031 slidably sleeved outside the spring mounting rod 5010 and a telescopic unit 5032 for driving the pressure sleeve 5031 to move.

[0096] Specifically, such as Figure 5-Figure 5 As shown in (C), the opening of the spring supply groove 5040 faces upward, and the spring supply groove 5040 is inclined downward. Its lower end is the output end, and it is provided with a spring mounting positioning plate 5041 fixedly connected to its two side walls. The higher end is the input end. The groove width of the spring supply groove 5040 is the same as the thickness of the spring 1130, and the groove depth is less than or equal to the outer diameter of the spring 1130. In this way, it is convenient to neatly arrange the springs 1130 to be loaded into the workpiece 1100 in the spring supply groove 5040. The springs 1130 can be added manually at the input end of the spring supply groove 5040. Of course, in order to save manpower, it can also be used to connect a vibratory feeder. The manufacturers of vibratory feeders are as mentioned above. Since it is a mature existing technology, it will not be described in detail here.

[0097] Because the spring supply groove 5040 is inclined downward, the annular spring 1130 located in the spring supply groove 5040 rolls downward until the end spring 1130 contacts the spring mounting positioning plate 5041. When installing the spring 1130, the end spring 1130 is picked up by the spring mounting rod 5010 and then the spring 1130 is installed on the workpiece 1100. Meanwhile, the other springs 1130 roll downward along the inclined spring supply groove 5040 until the end spring 1130 abuts against the spring mounting positioning plate 5041.

[0098] The spring mounting rod 5010 extends vertically, with its bottom outer diameter smaller than the inner diameter of the spring 1130. Near its bottom, it has an annular groove 5011 coaxial with the groove. Thus, when the spring mounting rod 5010 is adjusted to the same height as the center of the spring 1130 at the output end of the annular groove 5011, and the annular opening of the spring 1130 faces the spring mounting rod 5010 (i.e., the axis of the spring 1130 passes through the bottom center of the spring mounting rod 5010), moving the spring mounting rod 5010 along the axis of the spring 1130 allows the spring to be mounted... The bottom end of the rod 5010 can enter the inside of the spring 1130. As the spring mounting rod 5010 continues to move, after the spring 1130 is taken out, the spring 1130 is stuck in the annular groove 5011 at the bottom end of the spring mounting rod 5010, thus completing the operation of taking out the springs 1130 one by one from the output end of the spring supply groove 5040. Then, the spring mounting rod 5010 is moved to the position seat 2000 directly above by the spring mounting moving assembly 5020, so that the spring 1130 can be pressed down onto the mounting groove 1111 of the workpiece 1100 by the pressing assembly 5030.

[0099] In this invention, the spring rod 5010 is hollow, and a strip-shaped through hole 5012 extending parallel to its own axial direction is provided on the spring rod 5010; the pressing assembly 5030 includes a pressure sleeve 5031, a telescopic unit 5032, a spring bolt 5033, a spring nut 5034, a telescopic compression spring 5035, a spring sliding rod 5036, and a spring protrusion 5037, wherein the pressure sleeve 5031 is slidably sleeved on the outside of the spring rod 5010, the spring sliding rod 5036 is slidably disposed on the inside of the spring rod 5010, and the spring bolt 5033 passes through the inside of the strip-shaped through hole 5012. The screw end of 5033 is threaded with a spring nut 5034. The spring mounting bolt 5033 and the spring mounting nut 5034 are fixedly connected to the spring mounting slide rod 5036 and the pressure sleeve 5031 through the threaded connection. The top of the spring mounting slide rod 5036 is located above the spring mounting rod 5010 and is fixedly connected to the spring mounting protrusion plate 5037. A telescopic unit 5032 is provided directly above the spring mounting protrusion plate 5037. The telescopic unit 5032 is a telescopic cylinder. A telescopic compression spring 5035 is sleeved on the spring mounting rod 5010. The top of the telescopic compression spring 5035 is connected to the spring mounting protrusion plate 5037 and the bottom is connected to the spring mounting rod 5010.

[0100] When the spring rod 5010, which is equipped with spring 1130 at the annular slot 5011, moves to directly above the positioning seat 2000, as Figure 5As shown in (A), at this time, the bottom end of the spring mounting rod 5010 is coaxial with the workpiece 1100 and has a clearance fit. At this time, the telescopic cylinder is activated, driving its piston rod to move downward, acting on the spring mounting slide rod 5036, causing the spring mounting slide rod 5036 to move downward inside the spring mounting rod 5010, compressing the telescopic compression spring 5035. At the same time, the spring mounting bolt 5033 drives the pressure sleeve 5031 to move downward, pressing down on the spring 1130 at the annular groove 5011, so that... Spring 1130 moves downward until it is pressed into the mounting groove 1111 of rubber sleeve 1110 of workpiece 1100, thus completing the installation of spring 1130. Then, telescopic cylinder drives piston rod to move upward. Under the action of telescopic compression spring 5035, spring mounting slide rod 5036 and pressure sleeve 5031 are pushed until pressure sleeve 5031 moves above annular groove 5011, so that spring mounting rod 5010 can pick up spring 1130 again from the output end of spring supply groove 5040.

[0101] The spring-loading moving assembly 5020 includes a first spring-loading cylinder 5021 and a second spring-loading cylinder 5022. The first spring-loading cylinder 5021 is arranged horizontally, and the second spring-loading cylinder 5022 is arranged vertically. The cylinder barrel of the first spring-loading cylinder 5021 is fixedly connected to the fourth bracket 1440 through a first spring-loading frame 5023. The piston rod is fixedly connected to a second spring-loading frame 5024. A first spring-loading slide rail 5025 is provided on the first spring-loading frame 5023 along the axis parallel to the first spring-loading cylinder 5021. The second spring-loading frame 5024 slides in cooperation with the first spring-loading slide rail 5025. The cylinder barrel of the second spring-loading cylinder 5022 and the cylinder barrel of the telescopic cylinder are fixed below the second spring-loading frame 5024. The piston rod of the second spring-loading cylinder 5022 is fixedly connected to a third spring-loading frame 5026. The third spring-loading frame 5026 is fixedly connected to the spring-loading rod 5010.

[0102] With the above structure, the first spring mounting bracket 5023 conveniently fixes the cylinder position of the first spring mounting cylinder 5021. The first spring mounting cylinder 5021 drives the second spring mounting cylinder 5022, the telescopic unit 5032, and the spring mounting rod 5010 to move horizontally. The first spring mounting slide rail 5025 guides the smooth movement of the second spring mounting bracket 5024. The second spring mounting cylinder 5022 drives the spring mounting rod 5010 to move vertically, adjusting the bottom position of the spring mounting rod 5010 for convenient... When the spring rod 5010 is on the side of the spring supply groove 5040 away from the processing table 1000, the spring rod 5010 can pick up the spring 1130 at the output end of the spring supply groove 5040. When the spring rod 5010 moves to the coaxial center line with the positioning seat 2000, the distance between the bottom end of the spring rod 5010 and the workpiece 1100 can be controlled so that after the pressure sleeve 5031 moves down, the spring 1130 in the annular groove 5011 can be pressed down into the mounting groove 1111 of the rubber sleeve 1110.

[0103] A further improvement is that the processing assembly also includes a detection assembly 9000, which is used to detect whether the positioning seat 2000 has rotated to the position corresponding to the spring mounting assembly 5000 and whether the spring 1130 has been installed on the positioning seat 2000 at the position corresponding to the turning and picking assembly. Specifically, the detection position includes two distance sensors 9010, which are respectively oriented toward the spring 1130 mounting position on the surface of the workpiece 1100 corresponding to their respective test positions.

[0104] like Figure 6 and Figure 6 As shown in (A), the detection component 9000 includes two distance sensors 9010. Both distance sensors 9010 are fixedly connected to the fifth bracket 1450. One distance sensor 9010 faces the position corresponding to the spring mounting component 5000, and the other distance sensor 9010 faces the middle position between the position corresponding to the spring mounting component 5000 and the position corresponding to the unloading component 6000. The height of the distance sensor 9010 is the same as the height position of the workpiece 1100 mounting groove 1111 on the positioning seat 2000.

[0105] With the above design, the distance sensor 9010, which is positioned relative to the spring assembly 5000, can easily determine whether the positioning seat 2000 and the workpiece 1100 have rotated to the target position. Since the relative positions of the six positioning seats 2000 on the processing table 1000 are fixed, it can also be used to determine whether the other five positioning seats 2000 have reached the corresponding working position, which facilitates the feeding assembly 3000, the clamping assembly 8000, the cutting assembly 4000, the detection assembly 9000, and the unloading assembly 6000 to perform corresponding processing operations. The other distance sensor 9010 can detect whether the spring 1130 has been successfully installed in the mounting groove 1111 of the rubber sleeve 1110 of the workpiece 1100, thereby determining whether the product is qualified.

[0106] After the workpiece 1100 is inspected to determine if it is qualified, the rotating component 7000 drives the processing table 1000 to continue rotating by 60°, so that the workpiece 1100 rotates to the position corresponding to the unloading component 6000, so that the unloading component 6000 can perform the corresponding inspection according to whether the product is qualified.

[0107] A further improvement is that the unloading assembly 6000 is a sorting assembly for screening and collecting workpieces 1100 based on whether they are qualified. The sorting assembly includes a finished product box 6010, a waste product box 6020, a sorting moving assembly 6030, and a sorting clamp 6040. The sorting moving assembly 6030 drives the sorting clamp 6040 to move so that after clamping the workpieces 1100 on the positioning seat 2000, qualified workpieces 1100 with springs 1130 installed are put into the finished product box 6010, and workpieces 1100 without springs 1130 installed are put into the waste product box 6020.

[0108] Specifically, both the finished product box 6010 and the scrap box 6020 have open tops and are located on the lower side of the processing table 1000. A finished product channel 6011 is provided between the finished product box 6010 and the processing table 1000. The finished product channel 6011 is inclined downwards, with its higher end adjacent to the outer circumferential edge of the processing table 1000 and its lower end located directly above the finished product box 6010. A scrap channel 6021 is provided between the scrap box 6020 and the processing table 1000. The scrap channel 6021 is inclined downwards, with its higher end adjacent to the outer circumferential edge of the processing table 1000 and its lower end located directly above the scrap box 6020. The higher ends of the finished product channel 6011 and the scrap channel 6021 are distributed in a horizontal direction, which is the first horizontal direction. The horizontal direction perpendicular to the first horizontal direction is the second horizontal direction.

[0109] The sorting clamp 6040 preferably adopts a pneumatic clamp of the same type as the feeding clamp 3030 in the feeding assembly 3000. The sorting moving assembly 6030 preferably adopts a three-axis moving device, which can drive the sorting clamp 6040 to move along the vertical direction, the first horizontal direction, and the second horizontal direction.

[0110] When the processing table 1000 drives the positioning seat 2000 to rotate to the position corresponding to the unloading assembly 6000, the sorting moving assembly 6030 drives the sorting clamp 6040 to move directly above the positioning seat 2000 and the workpiece 1100. Then, the sorting clamp 6040 is moved downward to facilitate the sorting clamp 6040 clamping the workpiece 1100. After clamping the workpiece 1100, the sorting clamp 6040 is moved upward. Then, the sorting moving assembly 6030 controls the sorting clamp 6040 to move along the first horizontal direction according to the detection result of the workpiece 1100. Specifically, if the workpiece 1100... If the workpiece 1100 is qualified, the sorting clamp 6040 is moved above the higher end of the finished product channel 6011, and the sorting clamp 6040 releases the workpiece 1100, allowing the qualified workpiece 1100 to move down the finished product channel 6011 into the finished product box 6010. If the workpiece 1100 is unqualified, the sorting clamp 6040 is moved above the higher end of the scrap channel 6021, and the sorting clamp 6040 releases the workpiece 1100, allowing the unqualified workpiece 1100, which is not accurately fitted with the spring 1130, to move down the scrap channel 6021 into the scrap box 6020. This operation completes the product sorting process, separating qualified products from defective products and preventing defective products from being mixed into the final product shipment, thus ensuring the final product qualification rate.

[0111] The specific structure of the sorting moving component 6030 is as follows: Figure 6 (B) and Figure 6As shown in (C), the system includes a sorting frame 6050, a first sorting cylinder 6031, a second sorting cylinder 6032, and a third sorting cylinder 6033. The sorting frame 6050 is fixedly connected to a fifth support 1450. The cylinder barrel of the first sorting cylinder 6031 is fixed to the sorting frame 6050, and the piston rod is fixedly connected to a first sorting frame 6035. The first sorting frame 6035 is provided with a first sorting slide rail 6036 extending along a first horizontal direction and a second sorting cylinder 6032 arranged along the first horizontal direction. The cylinder barrel of the second sorting cylinder 6032 is fixedly connected to the first sorting frame 6035, and the piston rod is fixedly connected to a second sorting frame 6037. The second sorting frame 6037 is connected to the first sorting frame 6035. The sorting slide rail 6036 is slidably engaged. The second sorting frame 6037 is provided with a second sorting slide rail 6038 extending in the vertical direction and a third sorting cylinder 6033 extending axially in the vertical direction. The cylinder barrel of the third sorting cylinder 6033 is fixedly connected to the second sorting frame 6037, and the piston rod is fixedly connected to the third sorting frame 6039. The third sorting frame 6039 is slidably engaged with the second sorting slide rail 6038 and is fixedly connected to the sorting clamp 6040 through the sorting connecting frame 6060. The first sorting frame 6035 is fixedly connected with a sorting guide rod 6034 extending in the second horizontal direction. The sorting guide rod 6034 seals through the sorting fixing frame 6050 and is slidably engaged with the sorting fixing frame 6050.

[0112] With the above structure, the sixth bracket 1460 is used to fix and support the sorting frame 6050. The first sorting cylinder 6031 drives the first sorting frame 6035 to move along the second horizontal direction, which in turn drives the sorting clamp 6040 to move along the second horizontal direction. The sorting guide rod 6034 ensures the smooth movement of the first sorting frame 6035, so that the sorting clamp 6040 moves to directly above the positioning seat 2000, or directly above the higher end of the finished product channel 6011 and the higher end of the waste channel 6021. The second sorting cylinder 6032 can drive the second The sorting frame 6037 moves along the first horizontal direction so that the position of the sorting clamp 6040 is adjusted to be directly above the higher end of the finished product channel 6011 or the higher end of the waste channel 6021. The first sorting slide rail 6036 ensures the smooth movement of the second sorting frame 6037 and the sorting clamp 6040. The third sorting cylinder 6033 drives the third sorting frame 6039 to move smoothly along the vertical direction under the guidance of the second sorting slide rail 6038, thereby driving the sorting clamp 6040 to move up and down, so as to conveniently clamp the workpiece 1100 on the positioning seat 2000. Thus, the sorting moving component 6030 formed by the above-mentioned three-axis moving device can easily clamp the workpiece 1100 on the positioning seat 2000, and according to the detection result of the workpiece 1100, the qualified product workpiece 1100 is put down into the finished product channel 6011, and the unqualified product workpiece 1100 is put down into the scrap channel 6021, so that the qualified products are finally piled up in the finished product box 6010 and the scrap is piled up in the scrap box 6020, thereby completing the separation and collection of qualified products and defective products.

[0113] After workpiece 1100 is removed from positioning seat 2000, positioning seat 2000 rotates again with processing table 1000. Processing table 1000 rotates 60°, allowing positioning seat 2000 to move to the position corresponding to feeding assembly 3000. This facilitates feeding assembly 3000 loading workpiece 1100, which is to be cut or spring-loaded, onto positioning seat 2000 for subsequent processing. This achieves cyclic processing, significantly improving production efficiency, effectively distinguishing between qualified and defective products, reducing worker workload, and lowering labor costs.

[0114] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
