[0002] In the composition structure of the gas meter, the valve seat is a component with multiple different air passages, used in conjunction with the valve cover to guide the gas into different metering chambers. As a measuring instrument, the structural dimensions of the gas meter components have high industry requirements, such as surface roughness, flatness, etc. During the production process, it needs to be deburred, ground and polished.

[0003] Related technologies can refer to the Chinese patent application with publication number CN118577681A, which discloses a rapid production line for gas meter meter shells, including a meter shell punching machine with a discharge port, a batch glue coating device, including multiple glue coating conveying lines, and a glue coating mechanism corresponding to the glue coating conveying lines; a transfer module is provided between the meter shell punching machine and the batch glue coating device, including a transfer conveying line A, a transfer conveying line B and a feeding mechanism, and a flipping mechanism is provided between the transfer conveying line A and the transfer conveying line B. The transfer conveying line A is used to receive the meter shell sent from the discharge port, and the meter shell enters the transfer conveying line B with the concave surface facing upward after being flipped by the flipping mechanism, and the feeding mechanism delivers the meter shell located on the transfer conveying line B to the glue coating conveying line. With the above scheme, the meter shell quickly enters the glue coating device after stamping, which greatly improves the production efficiency of the meter shell, and the overall layout is compact and reasonable, which is conducive to reducing the space occupied by the site, while optimizing the glue coating device, improving the glue coating quality, and ensuring the good production quality of the meter shell finished product.

[0004] Regarding the above-mentioned related technologies, since the processed valve seats are in batches and are not assembled into gas meters in a timely manner, higher requirements are also placed on the storage and transportation of finished valve seats, and strong vibration, extrusion, collision, tumbling, moisture, heat, packaging damage, dust, etc. should be avoided. Under the basic performance indicators of these products themselves, with the development of intelligence and automation, the requirements for increased production capacity have also put forward higher requirements on the overall production efficiency of the product production line, such as the degree of automation, grinding efficiency per unit time, production line transportation efficiency, stacking efficiency, packaging effect, inspection efficiency of defective products, etc., which comprehensively affect the overall production efficiency of the production line. Therefore, a comprehensive production line is urgently needed to improve the production efficiency of valve seats. Summary of the invention

The grinder is provided with several grinding positions for simultaneously grinding multiple valve seats, and the valve seat pre-installation mechanism has multiple preset positions corresponding to the grinding positions, and the valve seat is placed at the preset position according to the grinding position of the grinder; the cleaning station is arranged downstream of the grinding station, and is used to clean the valve seat after grinding; the stacking station is arranged at the tail end of the main production line, and includes a stacking mechanism for stacking and packing the valve seats after cleaning.

[0007] By adopting the above technical solution, after the injection molding machine has injection-molded the valve seat, the manipulator moves the valve seat to the folding water outlet station to remove the water outlet. After the water outlet is removed, the conveyor belt and the manipulator cooperate to automatically transport the valve seat to the sandblasting machine for sandblasting. During this process, the valve seat is temporarily cached in the buffer area. After the sandblasting is completed, the valve seat is transported to the baking machine for baking. After the baking is completed, the valve seat is transported to the grinding station.

During the grinding process, the valve seats can be placed in advance, which is conducive to improving the grinding efficiency of the valve seats. After the grinding is completed, the valve seats are placed in the cleaning station for cleaning. After the cleaning is completed, the main conveying member moves the valve seats to the stacking station, and stacks them through the stacking mechanism, thereby completing the production and processing of the valve seats. Multiple processing stations process the valve seats one by one, and each processing link cooperates with each other, which is conducive to improving the production efficiency of the valve seats.

[0008] Optionally, the baking station also includes a tray loading mechanism and a baking tray conveyor belt, a plurality of baking trays are placed on the baking tray conveyor belt, the tray loading mechanism is used to stack the valve seats in the baking trays, the baking machine is provided with a baking conveyor line which moves back and forth along the length direction, and a baking tray stacking mechanism is provided at the starting end of the baking machine for stacking baking trays on the baking conveyor line.

[0009] By adopting the above technical solution, after the tray loading mechanism places the valve seats one by one on the baking tray, the baking trays are placed from the baking tray conveyor line to the baking conveyor line for stacking through the baking tray stacking mechanism, thereby facilitating batch baking of the valve seats, which is beneficial to improving the use efficiency of the baking machine.

[0010] Optionally, the baking station also includes a baking tray reflux conveyor line, one end of the baking tray reflux conveyor line is located at the discharging end of the baking machine, and the other end is connected to the baking tray conveyor line. The discharging end of the baking machine is provided with a baking tray unloading mechanism for unloading the baking tray and placing the valve seat on the baking tray into the main production line. The end of the baking tray reflux conveyor line close to the discharging end of the baking machine is provided with a baking tray stacking mechanism 2 for stacking the unstacking baking trays.

[0011] By adopting the above technical scheme, the valve seat after baking is moved out from the discharge end of the baking machine along the baking conveyor line under the drive of the baking tray. At the same time, the stacked baking trays and valve seats are unloaded to the main production line through the baking tray unloading mechanism. At the same time, the empty baking tray is placed on the baking tray return conveyor line through the baking tray stacking mechanism 2, and the baking tray is returned from the discharge end of the barbecue oven to the feed end through the baking tray return conveyor line, and then waits for the next batch of valve seats to be baked, which is conducive to baking convenience.

[0012] Optionally, the grinding station further includes a CCD positioning mechanism for positioning the grinding disc to ensure that the grinding position is aligned with the pre-installation position of the valve seat pre-installation mechanism when the grinding disc is positioned.

[0013] By adopting the above technical solution, before grinding, the placement position of the valve seat is detected by the CCD positioning mechanism, thereby reducing the probability of the valve seat being deflected during the placement process and ensuring that the valve seat is aligned with the grinding position when entering under the grinding disc.

[0014] Optionally, the valve seat pre-installation mechanism includes a plurality of placement disks and a rotating frame, wherein the plurality of placement disks are arranged circumferentially along the rotating frame, and when the rotating frame is in operation, the placement disks are driven to circulate along the main production line, the grinding disk and the cleaning station in sequence, and the rotating frame is provided with a rotating member, and the rotating member is used to drive the placement disks to rotate around its own axis, and a plurality of positioning grooves are opened on the upper end of the placement disk, and positioning members for clamping the valve seat are provided in the positioning grooves, and the positioning grooves and the positioning members cooperate to form a preset position, and the grinding disk is located above the placement disk, and the grinding station also includes a lifting frame for driving the grinding disk to reciprocate vertically, and a plurality of grinding wheels corresponding to the positioning grooves are rotatably connected to the lower end of the grinding disk, and when the placement disk is directly below the grinding disk, the grinding wheel is directly opposite to the corresponding positioning groove.

[0015] By adopting the above technical solution, in the initial state, any placement disk is located near the main production line, and the adjacent placement disk is located directly below the grinding disk. The manipulator moves the valve seat one by one close to the positioning groove of the placement disk of the main production line, and the positioning groove is positioned by the positioning member. In the process of placing the valve seat, the rotating member drives the placement disk to rotate continuously, so that the idle positioning groove is always close to the main production line, thereby improving the convenience of the manipulator. When the placement disk is full of valve seats, the rotating member drives the placement disk to move below the grinding disk. At this time, another idle placement disk moves to the main production line again for loading. After the placement disk moves to below the grinding disk, the lifting frame drives the grinding disk to move downward, so that the grinding disk grinds the valve seat in the positioning groove through the grinding wheel. After the grinding is completed, the rotating frame rotates again to transport the polished valve seat to the cleaning station, thereby facilitating the cleaning of the valve seat. The placement and grinding of the valve seat are carried out simultaneously, which is conducive to improving the grinding efficiency of the valve seat.

[0016] Optionally, the positioning member includes a positioning plate, a clamping plate, a driving rod 1 and a driving rod 2. A movable frame is provided in the positioning groove, and the movable frame is slidably connected to the inner wall of the positioning groove along the axis direction of the placement disk. The driving rod 1 is fixedly connected to the placement disk, and is used to drive the movable frame to move vertically. The positioning plate is fixedly connected to one end of the movable frame away from the axis of the placement disk and is arranged vertically. The clamping plate is located at one end of the movable frame away from the positioning plate and is opposite to the positioning plate. The driving rod 2 is fixedly connected to the movable frame, and is used to drive the clamping plate to approach or move away from the positioning plate.

[0017] By adopting the above technical solution, when the manipulator places the valve seat into the positioning groove and it is between the positioning plate and the clamping plate, under the support of the movable frame, the driving rod 2 drives the clamping plate to approach the valve seat, so that the clamping plate and the positioning plate cooperate to clamp and position the valve seat. The driving rod 1 is used to drive the movable frame to move along the axis direction of the placement disk to adjust the position of the positioning plate and the clamping plate, which is beneficial to improve the convenience of using the positioning plate and the clamping plate.

[0018] Optionally, a swivel is connected to the outer side of the placement disk for circumferential rotation, and the rotating member drives the placement disk to rotate around the axis of the swivel. A rotating column is fixedly connected to the side of the swivel close to the support frame. The rotating column is vertically connected to the rotating frame for rotation. The rotating frame is provided with a rotating motor for driving the rotating column to rotate. The positioning groove passes through the placement disk along the axis of the placement disk. The grinding station is also provided with multiple sets of lifting members. During the valve seat positioning and grinding process, the lifting members support the valve seat.

[0019] By adopting the above technical solution, when the valve seat is placed in the placement plate, the lifting member supports the valve seat so that the positioning plate and the clamping plate are in the middle position of the valve seat. After the grinding of one end of the valve seat is completed, the rotating motor drives the rotating column to rotate. Under the connection of the swivel, the rotating column drives the placement plate to flip. At this time, the moving frame is driven to move by the driving rod 2, so that the other end of the valve seat extends out of the positioning groove, which is conducive to improving the convenience of grinding both sides of the valve seat.

[0020] Optionally, the lifting member includes a fixed frame, a lifting platform, a plurality of supporting rods and a plurality of lifting plates. The fixed frame is located on one side of the rotating frame, the lifting platform is located at the upper end of the fixed frame and moves back and forth vertically, the upper end of the lifting plate is rotatably connected to a support ring, the plurality of supporting rods correspond one-to-one to the positioning grooves, and are all fixed to the upper end of the support ring, the lifting plates correspond one-to-one to the supporting rods, the supporting rods vertically pass through the lifting plates and are connected to the lifting plates, a stop block is fixedly connected to the upper end of the lifting plate, and when the stop block is in the positioning groove, it fits with the inner wall of the positioning groove, and the lifting platform is provided with a locking member for locking the support ring to rotate along its own circumferential direction.

[0021] By adopting the above technical solution, in the initial state, the locking member positions the support ring so that the support rod on the support ring is opposite to the positioning groove. When the valve seat is placed in the placement plate or the valve seat is ground, the lifting platform moves upward under the support of the fixed frame, so that the support rod enters the positioning groove to support the valve seat. At this time, the lifting plate drives the block to enter the positioning groove, and then blocks the positioning groove. At this time, the locking member releases the lock on the support ring, so that when the placement plate rotates, the support ring is driven to rotate through the block, the lifting plate and the support rod.

[0022] Optionally, a retaining ring is connected to the outer side of the placement disk in an axial sliding manner, and the retaining ring is connected to the movable frame. When the movable frame moves, the retaining ring is driven to move, and the inner diameter of the retaining ring is adapted to the grinding disk. When the valve seat is ground, the grinding disk is located in the retaining ring and fits against the inner wall of the retaining ring. An air pipe 1 is fixedly provided at the lower end of the grinding disk. The air pipe 1 is arranged horizontally. The placement disk is provided with an exhaust hole connected to the positioning groove, one end of the exhaust hole is located at the upper end of the placement disk, and the other end is located at the inner wall of the positioning groove. An air pipe 2 corresponding to the exhaust hole is fixedly connected to the lower end of the grinding disk, and an air source component for conveying high-speed airflow to air pipes 1 and 2 is fixed at the upper end of the grinding disk. The retaining ring is hollow, and an air inlet is opened on one side of the retaining ring close to the axis, and an exhaust port is opened on the other side, and a filter is detachably connected to the exhaust port.

[0023] By adopting the above technical solution, when the grinding disc drives the grinding wheel to contact the valve seat, the grinding disc is located in the retaining ring. At this time, the air pipe two is connected with the upper end of the exhaust port. During grinding, the air source component transports airflow to the air pipe one and the air pipe two. The airflow in the air pipe one pushes the grinding waste above the grinding disc to the air inlet of the retaining ring. The airflow in the air pipe two enters the positioning groove along the exhaust hole, thereby facilitating the removal of impurities in the positioning groove. The impurities pass through the air inlet and enter the retaining ring. At this time, the airflow passes through the filter and is discharged from the exhaust port, and the impurities remain in the retaining ring, thereby facilitating the collection and cleaning of the dust generated during the grinding process.

[0024] Optionally, an inspection station is provided between the cleaning station and the stacking station, and the inspection station includes a CCD selection mechanism, a CCD defect recognition mechanism, a plurality of grabbing robots and a return material conveyor line. The return material conveyor line is arranged on one side of the main production line. The CCD selection mechanism is used to position the valve seat on the main production line. The grabbing robot is arranged between the return material conveyor line and the main production line for grabbing and flipping the valve seat. The CCD defect recognition mechanism is arranged along the return material conveyor line for detecting and identifying defects in the valve seat.

[0025] By adopting the above technical solution, the CCD selection mechanism identifies the valve seat on the main production line, which makes it easier to adjust the valve seat through the robot. The valve seat is placed on the return material conveyor line by the grabbing robot, and the valve seat is detected and identified by the CCD defect recognition structure, which makes it easier to remove unqualified valve seats and improve the production quality of the valve seats.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the injection molding machine has injection-molded the valve seat, the manipulator will move the valve seat to the folding water outlet station to remove the water outlet. After the water outlet is removed, the conveyor belt and the manipulator will automatically transport the valve seat to the sandblasting machine for sandblasting. During this process, the valve seat will be temporarily cached in the buffer area. After sandblasting, the valve seat will be transported to the baking machine for baking. After baking, the valve seat will be transported to the grinding station. Multiple valve seats are placed in advance through the valve seat pre-installation mechanism, and then the placed valve seats are transported to the bottom of the grinding disc for grinding at one time. During the grinding process, the valve seats can be placed in advance, which is beneficial to improve the grinding efficiency of the valve seats. After grinding, the valve seats are placed in the cleaning station for cleaning. After cleaning, the main conveyor will move the valve seats to the stacking station, and the stacking mechanism will be used for stacking and stacking, thereby completing the production and processing of the valve seats. Multiple processing stations process the valve seats one by one, and each processing link cooperates with each other, which is beneficial to improve the production efficiency of the valve seats. 2. In the initial state, any placement disk is located close to the main production line. At this time, the adjacent placement disk is located directly below the grinding disk. The manipulator moves the valve seat one by one to the positioning groove of the placement disk of the main production line, and the positioning groove is positioned by the positioning member. In the process of placing the valve seat, the rotating member drives the placement disk to rotate continuously, so that the idle positioning groove is always close to the main production line, thereby improving the convenience of the manipulator's handling. When the placement disk is full of valve seats, the rotating member drives the placement disk to move below the grinding disk. At this time, another idle placement disk moves to the main production line again for loading. After the placement disk moves to the bottom of the grinding disk, the lifting frame drives the grinding disk to move down, so that the grinding disk grinds the valve seat in the positioning groove through the grinding wheel. After grinding, the rotating frame rotates again to transport the polished valve seat to the cleaning station, which is convenient for cleaning the valve seat. The placement and grinding of the valve seat are carried out simultaneously, which is conducive to improving the grinding efficiency of the valve seat. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the spring 577 is fixedly connected to the lifting plate 574, and the other end is fixedly connected to the lifting plate 574. In the natural state, the spring 577 pushes the lifting plate 574 away from the lifting platform 572.

[0049] Reference Figure 2 and Figure 6The upper end of the lifting plate 574 is fixedly connected with a stopper 576. When the stopper 576 enters the positioning groove 514 and fits with the inner wall of the positioning groove 514, the upper end surface of the lifting plate 574 contacts the lower end surface of the placement plate 511, and the lifting platform 572 continues to move. At this time, the lifting plate 574 and the supporting rod 573 produce relative displacement, and the spring 1 577 gradually deforms. The support platform is provided with a locking member for locking the rotation of the support ring 575. The locking member includes a push rod 581, a positioning rod 582, a positioning plate 583 and a spring 2 584. The positioning plate 583 is located between the support ring 575 and the lifting platform 572, and the positioning plate 583 is vertically connected to the lifting platform 572 in a sliding manner.

[0050] Reference Figure 2 and Figure 6 , spring 2 584 is located between the lifting platform 572 and the positioning plate 583, and one end of spring 2 584 is fixedly connected to the lifting platform 572, and the other end is fixedly connected to the positioning plate 583. In the natural state, spring 2 584 pushes the positioning plate 583 away from the lifting platform 572. There are multiple positioning rods 582, and the multiple positioning rods 582 are fixedly connected to the upper end of the positioning plate 583, and are arranged along the circumference of the positioning plate 583. When the positioning plate 583 moves, all the positioning rods 582 are driven to move. The lower end of the support ring 575 is provided with multiple positioning holes 579 corresponding to the positioning rods 582. In the initial state, the positioning rods 582 are inserted into the positioning holes 579 under the action of spring 2 584, thereby limiting the rotation of the support ring 575.

[0051] Reference Figure 2 and Figure 6 The push rod 581 is fixedly connected to the lower end of any lifting plate 574 and is parallel to the supporting rod 573. When the lifting plate 574 moves, the push rod 581 is driven to move. The support ring 575 is provided with an avoidance hole 578 corresponding to the push rod 581. When the lifting plate 574 approaches the lifting platform 572 along the supporting rod 573, the push rod 581 passes through the avoidance hole 578 and contacts the positioning plate 583. At this time, the lifting platform 572 continues to move, so that the push rod 581 pushes the positioning plate 583 away from the supporting ring 575, so that the positioning rod 582 moves out of the corresponding positioning hole 579, and the support ring 575 is unlocked.

[0052] Reference Figure 2 and Figure 5When the valve seat approaches the rotating frame 512 driven by the main production line, the valve seat is placed into the positioning groove 514 one by one by the manipulator. During this process, the supporting rod 573 in the positioning groove 514 initially supports the valve seat. The mobile frame 535 is located away from the lifting platform 572. The valve seat enters the positioning groove 514, and the driving rod 534 drives the clamping plate 532 to approach the valve seat, so that the positioning plate 531 and the clamping plate 532 cooperate to clamp and position the valve seat. After any positioning groove 514 has placed the valve seat, the rotating member 513 drives the placement plate 511 to rotate, so that the positioning groove 514 with the valve seat installed is moved out of the main production line, and the other empty positioning groove 514 is moved to the loading position. Under the action of the supporting rod 573 and the push block, when the placement plate 511 rotates, it drives the support ring 575 to rotate synchronously.

[0053] Reference Figure 2 and Figure 5 After all the valve seats are placed in the positioning grooves 514 on the same placement plate 511, the rotating frame 512 drives the placement plate 511 to move from the main production line to the bottom of the grinding plate 52, and supports the valve seat in the positioning groove 514 through the lifting member 57 at the grinding plate 52. Two retaining rings 59 are connected to the outer side of the placement plate 511 in a sliding manner along the axial direction. The two retaining rings 59 are respectively located on both sides of the rotating ring 55. The retaining rings 59 are connected to the moving frame 535. When the moving frame 535 moves, the retaining rings 59 are driven to move. The retaining rings 59 are hollow, and the retaining rings 59 are provided with an air inlet 591 on one side close to the placement plate 511, and an air outlet connected to the air inlet 591 on the other side, and a filter screen 593 is detachably connected to the air outlet. During the grinding process, the moving frame 535 is close to the upward end face of the placement plate 511, and the upper end of the retaining ring 59 extends to the upper end of the placement plate 511.

[0054] Reference Figure 4 and Figure 5 When the placement plate 511 moves to the bottom of the grinding plate 52, the lifting frame 54 drives the grinding plate 52 to move downward. When the lower end surface of the grinding wheel 521 contacts the upper end surface of the valve seat, the grinding plate 52 is located inside the retaining ring 59 and fits the inner wall of the retaining ring 59. At this time, the air inlet 591 is opposite to the gap between the grinding plate 52 and the placement plate 511. The grinding station 5 is provided with a CCD positioning mechanism, which is used to detect whether the grinding wheel of the grinding plate 52 is opposite to the valve seat in the positioning groove 514, so as to reduce the error rate of the grinding process.

[0055] Reference Figure 4 and Figure 5A lot of dust will be generated during the grinding process of the valve seat. The lower end of the grinding disc 52 is fixedly connected to the air pipe 1 522 and the air pipe 2 523, and the upper end of the grinding disc 52 is installed with an air source component 524 for conveying air to the air pipe 1 522 and the air pipe 2 523. The lower end of the air pipe 1 522 is horizontally arranged along the direction of the axis of the grinding disc 52 pointing to the outer edge. After the airflow is ejected along the air pipe 1 522, it pushes the dust on the upper end surface of the placement disc 511 to move toward the air inlet 591 of the retaining ring 59.

[0056] Reference Figure 4 and Figure 5 The placement plate 511 is provided with an exhaust hole 515 in the vertical direction. One end of the exhaust hole 515 is located on the upper end surface of the placement plate 511 and is directly opposite to the second air pipe 523. The other end of the exhaust hole 515 is connected to the positioning groove 514. During the grinding process, the second air pipe 523 is connected to the exhaust hole 515. The airflow in the second air pipe 523 enters the positioning groove 514 along the exhaust hole 515, thereby driving the dust in the positioning groove 514 to move and move the dust toward the retaining ring 59. The airflow entering the retaining ring 59 is discharged from the exhaust port 592. At this time, the filter net 593 filters the dust, which is conducive to improving the convenience of cleaning the dust.

[0057] Reference Figure 2 and Figure 5 After the grinding of the upper end surface of the valve seat is completed, the grinding disc 52 and the lifting member 57 are manipulated to reset. At this time, if it is necessary to grind the other end of the valve seat, the placement disc 511 is turned over by the rotating motor 56, and the moving frame 535 is driven to move along the axis direction of the placement disc 511 by the driving rod 1 533, and then the valve seat is driven to move by the clamping plate 532 and the positioning plate 531, so that the other end of the valve seat extends out from the positioning groove 514. At this time, the valve seat is supported by the lifting member 57 again, which makes it easier to grind both ends of the valve seat. When grinding different ends of the valve seat, there is no need to re-clamp and reposition the valve seat.

[0058] Reference Figure 1 and Figure 2 The cleaning station 6 is arranged downstream of the grinding station 5. The cleaning station 6 includes a cleaning box and a conveyor belt. The cleaning liquid is placed in the cleaning box. The conveyor belt is arranged along the length direction of the cleaning box. When the valve seat is ground, the rotating member 513 drives the placement plate 511 to approach the cleaning station 6, and the valve seat in the positioning groove 514 is placed on the conveyor belt through the manipulator, so that the conveyor belt drives the valve seat into the cleaning box for cleaning. A drying machine is arranged at the discharge end of the cleaning box, and the valve seat that has been cleaned is transported to the drying machine by the conveyor belt for drying.

[0059] Reference Figure 1The inspection station 8 includes a CCD selection mechanism, a CCD defect recognition mechanism, a plurality of grabbing manipulators and a return material conveyor line. The return material conveyor line is arranged on one side of the main production line. The CCD selection mechanism is used to position the valve seat on the main production line. When the valve seat is skewed, the valve seat is adjusted by the manipulator. The grabbing manipulator is arranged between the return material conveyor line and the main production line, and is used to grab the valve seat from the main production line to the return material conveyor line. The CCD defect recognition mechanism is arranged along the return material conveyor line, and is used to detect and identify the defects of the valve seat. During the inspection process, the valve seat is turned over by the grabbing manipulator, and then the different end faces of the valve seat are inspected, which is conducive to removing unqualified valve seats and improving the production quality of valve seats.

[0060] Reference Figure 1 The stacking station 7 is arranged at the tail end of the main production line, and includes an empty tray conveyor line, a full tray conveyor line and a depalletizing mechanism. A number of trays for placing valve seats are placed on the empty tray conveyor line. The depalletizing mechanism is used to stack the valve seats that have been cleaned into the trays. The full tray conveyor line is arranged at the tail end of the empty tray conveyor line, and is used to transport the pallets that have been stacked to the storage area.

[0061] The working principle of the automated processing production line of a gas meter valve seat in the embodiment of the present application is as follows: after the injection molding machine has injection-molded the valve seat, the valve seat is transported to the folding water outlet station 2 by a manipulator to remove the water outlet. After the water outlet is removed, the main production line automatically transports the valve seat to the sandblasting station 3 for sandblasting. After the sandblasting is completed, the valve seat is transported to the baking station 4 for baking. During the baking process, the valve seat is accommodated and supported by the baking tray, thereby improving the baking efficiency of the valve seat. After the baking is completed, the main production line transports the valve seat to the grinding station 5. The valve seat is supported and pre-placed by the placement plate 511, and the multiple placed valve seats are transported to the bottom of the grinding plate 52 for grinding. During the grinding process, there is an empty placement plate 511 for continuing to place the valve seats. The placement process and the grinding process of the valve seats are carried out simultaneously, which is beneficial to improving the grinding efficiency of the valve seats. After grinding, the valve seats are placed in the cleaning station 6 for cleaning. After cleaning, the main conveying member moves the valve seats to the stacking station 7, and stacks them through the stacking mechanism to complete the production and processing of the valve seats. Each processing link cooperates with each other, which is beneficial to improving the production efficiency of the valve seats.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
