Description

Technical Field

[0001] This invention belongs to the field of quartz machining technology, and particularly relates to an automatic turnover system and method for parts in the quartz machining industry. Background Technology

[0002] The quartz processing industry is mainly divided into two parts: machining and fire processing. Quartz machining is similar to metal processing, mainly using production equipment to perform fine processing on the shape of parts. However, due to the characteristics of quartz material, the parts to be processed cannot be piled up in large quantities next to the production equipment as in the metal processing industry. They need to undergo a series of operations such as dewaxing and bonding in the dewaxing chamber before they can be machined. Currently, after processing, the parts are mainly moved by manual pushing of small carts.

[0003] The current manual parts turnover process in the quartz machining industry is as follows: 1. After the production equipment finishes processing, the worker removes the parts and places them on a trolley; 2. The worker sends the parts to the dewaxing chamber for dewaxing; 3. Based on the next part to be processed by the production equipment, the worker selects the corresponding part from the waxed finished products and moves it onto the trolley; 4. The worker pushes the trolley to the production equipment and moves the parts onto the processing platform; 5. After performing operations such as tool setting and zero point finding, the corresponding program is selected to start processing. During the manual parts turnover process, the frequency of manual transfer is high, and the inability to promptly turn over the parts after the equipment finishes the previous one leads to equipment idleness and low overall equipment utilization rate; the overall level of automation is low, the labor intensity is high, the time required for workers to handle parts is long, and the overall work efficiency is low. With the continuous development of the quartz machining industry, more and more manufacturers are involved in the quartz machining industry. Under the increasingly fierce industry competition, the overall utilization rate and automation level of equipment are particularly important. At present, the parts turnover method that is completely handled by manual labor has become the main obstacle to improving the overall utilization rate of equipment. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing an automated parts turnover system and method for the quartz machining industry. This system reduces equipment downtime, enables uninterrupted production, eliminates the need for manual intervention in the entire turnover process, frees up manpower, and improves employee work efficiency.

[0005] In view of this, the present invention provides an automated turnover method for parts in the quartz machining industry, comprising the following steps: S1: The production management system automatically outputs a list of subsequent parts processing sequences; S2: In the waxing and dewaxing room, employees perform waxing operations on the parts to be processed according to the list in order. After waxing, the finished waxed products and their storage locations are scanned and bound. S3: The production management system automatically monitors the processing status of production equipment. Based on the current processing progress of the parts, it issues the next part handling task to the turnover cart within a preset time before the processing is completed. The turnover cart scheduling system automatically determines the task endpoint based on the required part information and the storage information of the parts on the automatic turnover loading and unloading components. S4: The turnover vehicle moves from the rest area to the empty turnover rack turnover area, lifts the empty turnover rack, and then lowers the turnover rack after taking the empty turnover rack to the designated destination. S5: The production management system determines that the turnover cart has reached the designated position, and the automatic turnover loading and unloading component loads the stored parts to be processed onto the turnover rack. S6: The turnover cart, carrying the turnover rack and the parts to be processed, arrives at the corresponding production equipment, puts down the turnover rack, and leaves. S7: After the current part is processed, the production equipment staff removes the finished product and places it on the empty layer of the turnover rack. The workpiece to be processed is removed from the turnover rack and clamped onto the production equipment. The production management system automatically imports the processing program of the workpiece to be processed and starts processing. S8: When the production management system detects that the part has started processing, it automatically issues a transfer task to send the finished product into the dewaxing chamber for dewaxing. The transfer vehicle scheduling system determines the current idle storage position of the automatic transfer loading and unloading component as the destination of the transfer task. S9: The turnover cart goes to the front of the corresponding production equipment to lift the turnover rack, and takes the turnover rack and parts to the endpoint position determined in S8. After arriving at the idle storage position of the automatic turnover loading and unloading component, the automatic turnover loading and unloading component unloads the parts from the turnover rack and puts the parts into the storage position to wait for dewaxing. S10: The turnover cart re-lifts the turnover rack, carries the turnover rack to the empty turnover rack turnover area, and leaves after putting down the empty turnover rack; S11: When the storage space of the automatic turnover loading and unloading component is full, the production management system will issue a reminder. Employees will enter the dewaxing chamber to remove the finished products stored on the automatic turnover loading and unloading component and perform dewaxing. The overall parts turnover process is then completed.

[0006] In this technical solution, the MMS production management system calls in advance based on processing time and information on subsequent parts to be processed. The turnover cart automatically transports the parts, ensuring that the parts to be processed are already waiting in front of the production equipment before the parts are finished, reducing equipment downtime and achieving uninterrupted production. At the same time, the MMS production management system automatically imports the processing program of the next part to be processed, reducing the risk of errors in part selection and corresponding program selection. It also reduces the time spent by employees in handling and during the handling process, ensuring that employees are always ready in front of the processing machine, greatly improving employee work efficiency. The entire turnover process does not require manual intervention, freeing up manpower and improving employee work efficiency.

[0007] Furthermore, an automated parts turnover system for the quartz machining industry, applicable to the aforementioned automated parts turnover method for the quartz machining industry, includes: A turnover rack, which is used to hold work parts; An automatic turnover loading and unloading assembly is used to temporarily store parts to be processed and parts after processing, and to load the parts to be processed onto the turnover rack, and to receive the parts after processing unloaded from the turnover rack. A turnover cart, used to transport turnover racks between automatic turnover loading and unloading components and production equipment for moving parts; A production management system is used to control the movement of turnover carts and the automatic import of parts processing programs within the equipment.

[0008] In this technical solution, the MMS production management system calls in advance based on processing time and information on subsequent parts to be processed. The turnover cart automatically transports the parts, ensuring that the parts to be processed are already waiting in front of the production equipment before the parts are finished, reducing equipment downtime and achieving uninterrupted production. At the same time, the MMS production management system automatically imports the processing program of the next part to be processed, reducing the risk of errors in part selection and corresponding program selection. It also reduces the time spent by employees in handling and during the handling process, ensuring that employees are always ready in front of the processing machine, greatly improving employee work efficiency. The entire turnover process does not require manual intervention, freeing up manpower and improving employee work efficiency.

[0009] Furthermore, the turnover rack includes: The storage layer comprises two layers, upper and lower, with support bars provided on each layer, and the storage layer is inclined. An elevated floor, located at the bottom, is used for access by turnover vehicles.

[0010] In this technical solution, the turnover rack adopts a double-layer stepped design, which not only ensures the placement and turnover needs of parts (one layer for parts to be processed and the other for finished products), but also makes it easier to pick up and put down parts on the lower layer. Simultaneously, it reduces the rack's footprint along its length. The inclined design ensures that the center of gravity of the parts is shifted backward during transport by the turnover cart, preventing parts from falling off the rack during sudden braking. The support bars are made of bakelite, primarily used to prevent gaps in the placement of parts, facilitating employee access. They are also heat-resistant and oil-resistant. A sealing strip is attached underneath, and the sealing strip is firmly pressed against the oil receiving tray by screws. This solves the problem of cutting fluid failure that can occur with adhesive-fixed support bars, and also avoids oil leakage caused by drilling holes in the oil receiving tray when using screw fixation.

[0011] Furthermore, the turnover rack also includes an oil receiving tray, with support bars set on the surface of the oil receiving tray. The oil receiving tray is set on the shelf and tilted at the same angle as the shelf. An oil outlet is provided at the lower part of the tilt of the oil receiving tray, and an oil collection pot is provided at the lower end of the oil outlet.

[0012] In this technical solution, the oil receiving tray is tilted so that the front end of the oil receiving tray is higher, which can ensure that the parts are placed on the shelf after machining, and the residual cutting fluid drips onto the oil receiving tray and flows to the lower rear end on its own, and then flows into the oil receiving can.

[0013] Furthermore, casters are installed at the four corners of the bottom of the turnover rack, a file box is installed on the side of the turnover rack, and rack weights are installed on the turnover rack.

[0014] Furthermore, the turnover rack is also equipped with auxiliary fixing brackets, which include: The base is magnetically attached to the rear side of the oil receiving tray. A connecting frame, one end of which is connected to the machine base, and the other end is connected to a V-shaped block, with Velcro attached to the plastic block.

[0015] In this technical solution, the connecting frame includes a universal joint structure, and the V-block can assist in fixing the parts to prevent them from tipping over during transportation.

[0016] Furthermore, the automatic turnover loading and unloading assembly includes a frame, on which are mounted: A transfer storage module, which is used to temporarily store parts to be processed and parts after processing; The loading and unloading module is used to load the parts to be processed from the transfer storage module to the turnover rack and unload the processed parts from the turnover rack to the transfer storage module.

[0017] In this technical solution, by setting up a transfer and storage module, the parts to be processed after waxing and the parts to be dewaxed after processing can be temporarily stored on the automatic turnover loading and unloading assembly. This allows operators to work only at the transfer and storage module without having to run around the workshop. The workflow is simple and easy to manage. Furthermore, the loading and unloading module works in conjunction with the turnover rack to realize automatic loading and unloading of parts and improve production efficiency.

[0018] Furthermore, the transfer storage module includes two temporary storage racks arranged vertically, each with multiple temporary storage areas, and a loading / unloading module is provided on one side of the temporary storage rack on the frame.

[0019] Furthermore, adjacent temporary storage areas are separated by slide rails, and each temporary storage area has a slide rail on each side. The support member is connected to the slide rails on both sides. The support member includes a horizontal plate and fork plates perpendicular to both ends of the horizontal plate. The two fork plates are used to support the placement tray, which is used to hold the parts. The distance between the two fork plates is greater than the length of the support bar on the turnover rack and less than the width of the placement tray.

[0020] Furthermore, the loading and unloading module includes a loading and unloading cylinder, and the output end of the loading and unloading cylinder is equipped with an electromagnet, which can attract the support component when energized.

[0021] In this technical solution, the transfer storage module and the turnover rack are at the same height and are also designed as a double-layer structure, with the upper and lower layers having identical structures. After the turnover rack moves to the temporary storage area corresponding to the transfer storage module driven by the turnover trolley, the piston rod of the loading / unloading cylinder extends. When the inductive sensor fixed at the front end of the piston rod detects that it is close to the support component, the electromagnet is energized, attracting the support component and realizing the pushing and pulling action of the support component. Specifically, the loading / unloading cylinder pushes out the support component containing the placement tray. The support component reaches the top of the turnover rack's shelf, with the two forks located outside the two support bars on the turnover rack. Then, the turnover trolley lifts the turnover rack so that the upper surface of the two support bars supports the placement tray, thus separating the placement tray from the forks of the support component. Then, the piston rod of the loading / unloading cylinder retracts, taking the support component back to its original position. The specific unloading operation is as follows: after the loading and unloading cylinder pushes out the support component containing the placement tray, the support component reaches the upper layer of the turnover rack. The two forks are located outside the two support bars on the turnover rack. Then, the turnover cart lowers the turnover rack so that the upper surface of the two forks supports the placement tray. The placement tray separates from the two support bars on the turnover rack. Then, the piston rod of the loading and unloading cylinder retracts and moves the support component and the placement tray machine parts to the temporary storage area.

[0022] Furthermore, the horizontal plate is L-shaped and includes two perpendicular vertical plates, one of which is used to magnetically attract the electromagnet, and the other vertical plate is used to fixally connect to the fork plate.

[0023] Furthermore, a vertical plate is vertically connected to the ends of the two fork plates that are far apart from each other, and the vertical plate is slidably connected to the slide rail.

[0024] Furthermore, each temporary storage rack has a mounting bracket on one side, and each mounting bracket is fixedly equipped with: A linear track, on which a slider is slidably mounted, and a loading / unloading cylinder is fixedly mounted on a fixed plate. The fixed plate and the slider are fixedly connected so that the loading / unloading cylinder is slidably connected to the linear track. The sliding direction of the loading / unloading cylinder is perpendicular to the extension / retraction direction of the cylinder piston. A drive motor, which is fixedly installed; The synchronous belt is driven by a drive motor to rotate, and the synchronous belt is connected to a fixed plate to move the fixed plate.

[0025] In this technical solution, the drive motor drives the synchronous belt to rotate, enabling the fixed plate and loading / unloading cylinders to move to any position, thus realizing the pushing and pulling of parts in any temporary storage area.

[0026] Furthermore, the automatic turnover loading and unloading assembly also includes an adjustment component, which is used to adjust the distance between the upper and lower temporary storage racks.

[0027] In this technical solution, under normal circumstances, parts of average height do not require adjustment of the distance between the upper and lower temporary storage racks. However, when processing excessively tall parts, the distance between the upper and lower temporary storage racks becomes too great to prevent unloading. Therefore, it is necessary to increase the distance between the upper and lower temporary storage racks to broaden the applicability of the automatic turnover loading and unloading assembly. This also requires the selection of turnover racks of the appropriate specifications. When the processed parts become of normal specifications, the racks are readjusted to prevent the center of gravity of the automatic turnover loading and unloading assembly from becoming too high, thus maintaining stability.

[0028] Furthermore, the adjustment component includes: An adjustment motor is fixedly mounted on the frame. An adjusting screw is connected to the output end of an adjusting motor. The temporary storage rack and the mounting rack are both slidably mounted on the frame, and the temporary storage rack and the mounting rack of each layer are fixedly connected. The adjusting screw is rotatably mounted on the frame and threadedly connected to the temporary storage rack below.

[0029] In this technical solution, when it is necessary to adjust the distance between the upper and lower temporary storage racks, the adjustment motor is started to rotate the adjustment screw, so that the lower temporary storage rack and the mounting rack move along the length direction of the adjustment screw. After the adjustment is completed, the adjustment motor stops.

[0030] Furthermore, the operating method of the automated turnover loading and unloading component includes the following steps: S1: Place the parts to be processed after waxing into the temporary storage area of ​​the transfer storage module; S2: The turnover rack moves down to the temporary storage area corresponding to the transfer storage module, driven by the turnover cart; S3: After the upper loading / unloading cylinder pushes out the support component containing the placement tray, the support component reaches the upper layer of the turnover rack. The two forks are located outside the two support bars on the turnover rack. Then, the turnover trolley lifts the turnover rack so that the upper surface of the two support bars supports the placement tray, thus separating the placement tray from the forks of the support component. Then, the piston rod of the loading / unloading cylinder retracts, taking the support component back to its original position, thus completing the loading. At the same time, after the lower loading / unloading cylinder pushes out the support component containing the placement tray, the support component reaches the upper layer of the turnover rack. The two forks are located outside the two support bars on the turnover rack. Then, the turnover trolley lowers the turnover rack so that the upper surface of the two forks supports the placement tray, separating the placement tray from the two support bars on the turnover rack. Then, the piston rod of the loading / unloading cylinder retracts, taking the support component and the placement tray machine parts to the temporary storage area, thus completing the unloading.

[0031] The beneficial effects of this invention are: 1. The MMS production management system automatically calls for processing time and subsequent parts to be processed based on processing time and subsequent parts information. The turnover cart automatically transports the parts, ensuring that the parts to be processed are already waiting in front of the production equipment before the parts are completed. This reduces equipment downtime and enables uninterrupted production. At the same time, the MMS production management system automatically imports the processing program of the next part to be processed, reducing the risk of errors in part selection and corresponding program selection. It also reduces the time spent by employees in handling and during the handling process, ensuring that employees are always ready in front of the processing machine, greatly improving employee work efficiency. The entire turnover process does not require manual intervention, freeing up manpower and improving employee work efficiency.

[0032] 2. The turnover rack adopts a double-layer tiered design, which ensures the placement and turnover needs of parts. One layer is used to place parts to be processed, and the other layer is used to place finished products. It also makes it easier to pick up and put down parts on the lower layer, while reducing the footprint of the rack in the length direction. The inclined design ensures that the center of gravity of the parts is at the rear during the turnover cart's transport, preventing parts from moving forward and falling off the rack during sudden braking. The support bars are made of bakelite, mainly to prevent gaps in the placement of parts and facilitate employee access. They can withstand certain high temperatures and are oil-resistant. A sealing strip is attached to the bottom of the support bars and is firmly pressed into the oil receiving tray by screws. This solves the problem of cutting fluid failure that can easily occur with adhesive-fixed support bars, and also solves the problem of oil leakage caused by drilling holes in the oil receiving tray when fixing with screws.

[0033] 3. The tilt of the oil tray makes the front end of the oil tray higher, which ensures that the parts are placed on the shelf after machining. The residual cutting fluid dripping into the oil tray can flow to the lower rear end and then into the oil can.

[0034] 4. The connecting frame includes a universal joint structure, and the V-block can assist in fixing the parts to prevent them from tipping over during transportation.

[0035] 5. The automatic turnover loading and unloading component, by setting up a transfer and storage module, can temporarily store parts that are to be processed after waxing and parts that are to be dewaxed after processing on the automatic turnover loading and unloading component. This allows operators to work only at the transfer and storage module without having to run around the workshop. The workflow is simple and easy to manage. In addition, the loading and unloading module works with the turnover rack to realize the automatic loading and unloading of parts and improve production efficiency.

[0036] 6. Under normal circumstances, parts of average height do not require adjustment of the distance between the upper and lower temporary storage racks. However, when processing excessively tall parts, the distance between the two racks may prevent unloading, necessitating an increase in the distance to broaden the applicability of the automatic turnover loading and unloading assembly. Therefore, it is also necessary to select turnover racks of the appropriate specifications. When processing parts of normal size, the racks should be adjusted back to their original position to prevent the center of gravity of the automatic turnover loading and unloading assembly from becoming too high and maintain stability.

[0044] Example 1: An automated turnover method for parts 31 in the quartz machining industry includes the following steps: S1: The production management system automatically outputs a list of processing sequences for subsequent parts 31; S2: In the waxing and dewaxing room, employees perform waxing operations on the parts to be processed 31 according to the list order. After waxing, the finished waxed products and their storage locations are scanned and bound. S3: The production management system automatically monitors the processing status of production equipment 4. Based on the current processing progress of part 31, it issues the next part 31 handling task to turnover cart 3 within a preset time before processing is completed. The scheduling system of turnover cart 3 automatically determines the task endpoint based on the required part 31 information and the storage information of part 31 on the automatic turnover loading and unloading component 2. S4: The turnover vehicle 3 moves from the rest area to the empty turnover rack 1, lifts the empty turnover rack 1 in the turnover area, and then lowers the turnover rack 1 after taking the empty turnover rack 1 to the designated destination. S5: The production management system determines that the turnover cart 3 has reached the designated position, and the automatic turnover loading and unloading component 2 loads the stored parts to be processed 31 onto the turnover rack 1. S6: The turnover cart 3, carrying the turnover rack 1 and the parts to be processed 31, arrives at the corresponding production equipment 4, puts down the turnover rack 1, and leaves. S7: After the current part 31 is processed, the production equipment 4 employee takes the finished product and places it on the empty layer of the turnover rack 1. The product to be processed is taken off the turnover rack 1 and clamped onto the production equipment 4. The production management system automatically imports the processing program of the part 31 to be processed and starts processing. S8: The production management system detects that part 31 has started processing and automatically issues a transfer task to the turnover car 3 to send the processed product into the dewaxing chamber for dewaxing. The turnover car 3 scheduling system determines the current idle storage position of the automatic turnover loading and unloading component 2 as the endpoint of the transfer task. S9: The turnover cart 3 goes to the front of the corresponding production equipment 4 to lift the turnover rack 1, and takes the turnover rack 1 and part 31 to the endpoint position determined in S8. After arriving at the idle storage position of the automatic turnover loading and unloading component 2, the automatic turnover loading and unloading component unloads the part 31 on the turnover rack 1 and puts the part 31 into the storage position to wait for dewaxing. S10: The turnover cart 3 re-lifts the turnover rack 1, carries the turnover rack 1 to the turnover area of ​​the empty turnover rack 1, and leaves after putting down the empty turnover rack 1. S11: When the storage space of the automatic turnover loading and unloading component 2 is full, the production management system will remind the employees to enter the dewaxing chamber and take out the finished products stored in the automatic turnover loading and unloading component 2 for dewaxing. The overall parts 31 turnover process is completed.

[0045] The MMS production management system calls in advance based on processing time and information on subsequent parts 31 to be processed, and the turnover cart 3 automatically transports them, ensuring that the parts to be processed are already waiting in front of the production equipment 4 before the parts 31 are completed, reducing equipment idle time and achieving uninterrupted production. At the same time, the MMS production management system automatically imports the processing program of the next part 31 to be processed, reducing the risk of errors in the selection of part 31 and corresponding program, and also reducing the time spent by employees in handling and during the handling process, ensuring that employees are always ready in front of the processing machine, greatly improving employee work efficiency. The entire turnover process does not require manual intervention, freeing up manpower and improving employee work efficiency.

[0046] Example 2: like Figure 1-4 As shown, an automatic turnover system for parts 31 in the quartz machining industry, applicable to the automatic turnover method for parts 31 in the quartz machining industry, includes: Turnover rack 1, the turnover rack 1 is used to hold the working parts 31; Automatic turnover loading and unloading assembly 2 is used to temporarily store the parts to be processed 31 and the processed parts 31, and to load the parts to be processed 31 onto the turnover rack 1, and to receive the processed parts 31 unloaded from the turnover rack 1. The turnover cart 3 is used to transport the turnover rack 1 between the automatic turnover loading and unloading assembly 2 and the production equipment 4 to move the parts 31; The production management system is used to control the movement of the turnover cart 3 and the automatic import of the processing program of the parts 31 in the equipment.

[0047] Example 3: like Figure 2-3 As shown, the turnover rack 1 includes: The storage layer 5 includes upper and lower layers, and each storage layer 5 is provided with a support bar 6. The storage layer 5 is inclined. The elevated floor 7, located at the bottom, is used for the passage of the turnover vehicle 3.

[0048] The turnover rack 1 adopts a double-layer stepped design, which not only ensures the placement and turnover needs of parts 31 (one layer for placing parts 31 to be processed, and the other for placing finished products), but also makes it easier to pick up and put down parts 31 on the lower layer. It also reduces the rack's footprint in the length direction. The inclined design ensures that the center of gravity of parts 31 is shifted backward during transport by the turnover cart 3, preventing parts 31 from falling out of the turnover rack 1 during sudden braking of the turnover cart 3. The support bar 6 is made of bakelite, mainly used to prevent gaps in the placement of parts 31, facilitating employee access. It can withstand certain high temperatures and is oil-resistant. A sealing strip is attached to its bottom, and the sealing strip is firmly pressed against the oil receiving tray 8 by screws. This solves the problem of cutting fluid failure when the support bar 6 is fixed by adhesive, and also solves the oil leakage problem caused by drilling holes in the oil receiving tray 8 when fixing with screws.

[0049] The turnover rack 1 also includes an oil receiving tray 8, with support bars 6 disposed on the surface of the oil receiving tray 8. The oil receiving tray 8 is disposed on the shelf 5 at the same angle of inclination as the shelf 5. An oil outlet hole 9 is provided at the lower end of the inclination of the oil receiving tray 8, and an oil collection container 10 is provided at the lower end of the oil outlet hole 9. The inclination of the oil receiving tray 8 makes the front end of the oil receiving tray 8 higher, which can ensure that the part 31 is placed on the shelf 5 after processing. The residual cutting fluid dripping onto the oil receiving tray 8 can flow to the lower rear end on its own and then into the oil collection container 10.

[0050] The turnover rack 1 is equipped with casters 11 at the four corners of the bottom, a file box 12 is provided on the side of the turnover rack 1, and a rack bar 13 is provided on the turnover rack 1.

[0051] The turnover rack 1 is also equipped with an auxiliary fixing frame 14, which includes: The base 15 is magnetically attached to the rear side of the oil receiving tray 8; The connecting frame 16 is connected to the base 15 at one end and to a V-shaped block 17 at the other end. The plastic block is provided with Velcro.

[0052] The connecting frame 16 includes a universal joint structure 18 and a V-block 17v that can assist in fixing the part 31 and prevent the part 31 from tipping over during transportation.

[0053] Example 4: like Figure 4-7 As shown, the automatic turnover loading and unloading assembly 2 includes a frame 19, on which are arranged: A transfer storage module is used to temporarily store the part 31 to be processed and the processed part 31; The loading and unloading module is used to load the parts 31 to be processed from the transfer storage module to the turnover rack 1 and unload the processed parts 31 from the turnover rack 1 to the transfer storage module.

[0054] By setting up a transfer and storage module, the parts 31 to be processed after waxing and the parts 31 to be dewaxed after processing can be temporarily stored on the automatic turnover loading and unloading assembly 2. This allows operators to work only at the transfer and storage module without having to run around the workshop. The workflow is simple and easy to manage. In addition, the loading and unloading module works with the turnover rack 1 to realize the automatic loading and unloading of parts 31 and improve production efficiency.

[0055] The transfer and storage module includes two temporary storage racks 20 arranged vertically, each temporary storage rack 20 having multiple temporary storage areas 21, and a loading and unloading module located on one side of the temporary storage rack 20 on the frame 19.

[0056] Two adjacent temporary storage areas 21 are separated by slide rails 22. Each temporary storage area 21 has a slide rail 22 on both sides. The support member 23 is connected to the slide rails 22 on both sides. The support member 23 includes a horizontal plate 24 and fork plates 25 perpendicular to both ends of the horizontal plate 24. The two fork plates 25 are used to support the placement tray 26, which is used to hold the parts 31. The distance between the two fork plates 25 is greater than the length of the support bar 6 on the turnover rack 1 and less than the width of the placement tray 26.

[0057] The loading and unloading module includes a loading and unloading cylinder 27, and an electromagnet 28 is provided at the output end of the loading and unloading cylinder 27. When the electromagnet 28 is energized, it can attract the support member 23. The transfer storage module is at the same height as the turnover rack 1 and is also set as a double-layer structure. The upper and lower layers are identical. After the turnover rack 1 moves to the temporary storage area 21 corresponding to the transfer storage module driven by the turnover cart 3, the piston rod of the loading and unloading cylinder 27 extends. When the inductive sensor fixed at the front end of the piston rod detects that it is close to the support member 23, the electromagnet 28 is energized, attracting the support member 23, realizing the pushing and pulling action of the support member 23. The specific loading operation is as follows: After the loading / unloading cylinder 27 pushes out the support member 23 containing the placement tray 26, the support member 23 reaches above the shelf 5 of the turnover rack 1. The two forks 25 are located outside the two support bars 6 on the turnover rack 1. Then the turnover cart 3 lifts the turnover rack 1 so that the upper surface of the two support bars 6 supports the placement tray 26. Then the placement tray 26 separates from the forks 25 of the support member 23. Then the piston rod of the loading / unloading cylinder 27 retracts and resets the support member 23. The specific unloading operation is as follows: After the loading and unloading cylinder 27 pushes out the support member 23 containing the placement tray 26, the support member 23 reaches above the shelf 5 of the turnover rack 1. The two forks 25 are located outside the two support bars 6 on the turnover rack 1. Then the turnover cart 3 lowers the turnover rack 1 so that the upper surface of the two forks 25 supports the placement tray 26. The placement tray 26 separates from the two support bars 6 on the turnover rack 1. Then the piston rod of the loading and unloading cylinder 27 retracts and moves the support member 23, the placement tray 26 and the machine parts 31 to the temporary storage area 21.

[0058] The horizontal plate 24 is L-shaped and includes two perpendicular vertical plates 29. One vertical plate 29 is used to magnetically attract the electromagnet 28, and the other vertical plate 29 is used to fixally connect to the fork plate 25. A vertical plate 30 is perpendicularly connected to one end of the two fork plates 25 that is far apart from each other. The vertical plate 30 is slidably connected to the slide rail 22.

[0059] Example 5: like Figure 7 As shown, each temporary storage rack 20 has a mounting bracket 32 ​​on one side, and each mounting bracket 32 ​​is fixedly equipped with: A linear track 33 is provided, on which a slider 34 is slidably arranged. The loading and unloading cylinder 27 is fixedly arranged on a fixed plate 35. The fixed plate 35 and the slider 34 are fixedly connected so that the loading and unloading cylinder 27 is slidably connected to the linear track 33. The sliding direction of the loading and unloading cylinder 27 is perpendicular to the extension and retraction direction of the cylinder piston. A drive motor 36 is fixedly installed. The synchronous belt 37 is driven by the drive motor 36 to rotate. The synchronous belt 37 is connected to the fixed plate 35 and can move the fixed plate 35.

[0060] The drive motor 36 drives the synchronous belt 37 to rotate, enabling the fixed plate 35 and the loading / unloading cylinder 27 to move to any position, thus realizing the pushing and pulling of parts 31 in any temporary storage area 21.

[0061] Example 6: like Figure 7-8 As shown, the automatic turnover loading and unloading assembly 2 also includes an adjustment component, which is used to adjust the distance between the upper and lower temporary storage racks 20. Under normal circumstances, parts 31 of average height do not require adjustment of the distance between the upper and lower temporary storage racks 20. However, when processing excessively tall parts 31, the distance between the upper and lower temporary storage racks 20 may prevent unloading, thus requiring an increase in the distance to broaden the applicability of the automatic turnover loading and unloading assembly 2. Therefore, a turnover rack 1 of the appropriate specifications must be selected accordingly. When the processed part 31 becomes of normal specifications, the distance is readjusted to prevent the center of gravity of the automatic turnover loading and unloading assembly 2 from becoming too high and maintain stability.

[0062] The adjustment component includes: An adjusting motor 38 is fixedly mounted on the frame 19. Adjusting screw 39 is connected to the output end of adjusting motor 38. Temporary storage rack 20 and mounting rack 32 are slidably mounted on frame 19 and fixedly connected to each layer of temporary storage rack 20 and mounting rack 32. Adjusting screw 39 is rotatably mounted on frame 19 and threadedly connected to the temporary storage rack 20 below.

[0063] When it is necessary to adjust the distance between the upper and lower temporary storage racks 20, start the adjustment motor 38 to rotate the adjustment screw 39, so that the lower temporary storage rack 20 and the mounting rack 32 move along the length of the adjustment screw 39. After the adjustment is in place, the adjustment motor 38 stops.

[0064] The working method of the automatic turnover loading and unloading component 2 includes the following steps: S1: Place the parts 31 to be processed after waxing into the temporary storage area 21 of the transfer storage module; S2: The turnover rack 1 moves down to the temporary storage area 21 corresponding to the transfer storage module, driven by the turnover cart 3; S3: After the upper loading / unloading cylinder 27 pushes out the support member 23 containing the placement tray 26, the support member 23 reaches above the shelf 5 of the turnover rack 1. The two forks 25 are located outside the two support bars 6 on the turnover rack 1. Then, the turnover cart 3 lifts the turnover rack 1 so that the upper surface of the two support bars 6 supports the placement tray 26, thus separating the placement tray 26 from the forks 25 of the support member 23. Then, the piston rod of the loading / unloading cylinder 27 retracts, taking the support member 23 back to its original position, thus completing the loading. At the same time, the lower loading / unloading cylinder... After cylinder 27 pushes out the support 23 containing the placement tray 26, the support 23 reaches above the shelf 5 of the turnover rack 1. The two forks 25 are located outside the two support bars 6 on the turnover rack 1. Then, the turnover cart 3 lowers the turnover rack 1 so that the upper surface of the two forks 25 supports the placement tray 26. The placement tray 26 separates from the two support bars 6 on the turnover rack 1. Then, the piston rod of the loading and unloading cylinder 27 retracts, moving the support 23 and the placement tray 26 and the machine parts 31 to the temporary storage area 21, thus completing the unloading.
