Technical Field

[0001] The present invention relates to the technical field of computer accessory processing, and particularly to an automatic feeding device for processing a heat dissipation fan cover plate. Background Art

[0002] In the production line of computer heat dissipation fans, in order to improve the heat dissipation effect and wear resistance of the heat dissipation fan cover plate, the cover plate structure usually needs to be processed multiple times. During the processing, in order to avoid damage to the cover plate due to pressure during transportation, multiple cover plates are usually supported by a tray, and the cover plates are transported to different processes through the tray.

[0003] In the prior art, when processing the cover plate, the cover plate is generally transported by manually carrying the tray. During the processing, operations such as feeding, discharging, and stacking of finished products of the cover plate require multiple workers to continuously carry the tray, resulting in low processing efficiency of the cover plate and easy damage to the cover plate due to human operation errors, and large-scale continuous processing of the heat dissipation fan cover plate cannot be carried out. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an automatic feeding device for processing a heat dissipation fan cover plate that is convenient for large-scale continuous processing of the cover plate.

[0005] An automatic feeding device for processing a heat dissipation fan cover plate includes a workbench and a tray for storing the cover plates. A feeding area, a to-be-processed area, a processed area, and a stacking area are sequentially arranged on the workbench. A conveying mechanism for gradually conveying the tray from the feeding area to the stacking area is provided on the top of the workbench; A feeding rack for storing to-be-processed cover plates is arranged in the feeding area. A discharging frame through which the tray can pass downward is provided at the top of the feeding rack. A first supporting component for supporting the tray is provided at the top of the discharging frame. A discharging mechanism for supporting the lifting of the tray is provided below the discharging frame. After the discharging mechanism abuts against the bottom of the tray, it supports the tray to drop onto the conveying mechanism; Side supporting mechanisms for vertically jacking up the tray and separating it from contact with the conveying mechanism are provided in both the to-be-processed area and the processed area; A stacking rack for storing processed cover plates is arranged in the stacking area. A feeding frame through which the tray can pass upward is provided at the top of the stacking rack. A second supporting component for supporting the tray is provided at the top of the feeding frame. A jacking mechanism for vertically jacking the tray to the top of the feeding frame is provided on the top of the workbench. The second supporting component abuts against the tray that has been jacked up to the top of the feeding frame.

[0006] By adopting the above technical solution, with the mutual cooperation of the conveying mechanism, the first supporting component, the feeding mechanism, the side supporting mechanism, the lifting mechanism and the third driving member, automatic feeding, conveying, stacking after processing and other processes of the cover plate can be realized, which is convenient for continuous mass processing of the heat dissipation fan cover plate to improve the production efficiency of the cover plate.

[0007] The present invention is further configured as: the conveying mechanism includes a sliding table, a conveying frame and a driving device for driving the conveying frame to slide horizontally along the sliding table. The sliding table is fixedly installed on the top of the workbench. Three conveying stations are provided on the top of the conveying frame. The conveying frame is slidably matched with the sliding table to gradually convey the tray from the loading area to the stacking area.

[0008] By adopting the above technical solution, when the driving device drives the driving conveying frame to slide along the sliding table, the positions of the three conveying stations can be switched to facilitate the gradual conveyance of the tray from the loading area to the stacking area.

[0009] The present invention is further configured as: a limiting plate for limiting the tray is fixedly connected to the conveying frame, and a through hole is formed at the end of the conveying frame for the feeding mechanism or the lifting mechanism to pass through and abut against the tray.

[0010] By adopting the above technical solution, the setting of the limiting plate prevents the tray from shifting due to inertia after the conveying frame stops, ensuring the stability of the tray during the conveying process. The setting of the through hole facilitates the feeding mechanism or the lifting mechanism to drive the tray to lift.

[0011] The present invention is further configured as: multiple groups of grooves are provided at the edge of the tray. The first supporting component includes a supporting block and a control member for driving the supporting block to move horizontally. The control member is installed on the top of the feeding frame. The control member drives the supporting block to abut against the groove to support the tray.

[0012] By adopting the above technical solution, when the feeding mechanism drives the tray to lift, the lowermost tray can be quickly separated by the cooperation of the groove and the supporting block, and the remaining trays after separation are supported to facilitate the subsequent placement of the remaining trays on the conveying frame.

[0013] The present invention is further configured as: the feeding mechanism includes a supporting block and a first driving member for driving the supporting block to lift. The first driving member is installed on the top of the workbench. After the first driving member drives the supporting block to pass through the through hole and abut against the bottom of the tray, the supporting block supports the tray to move downward from the top of the feeding frame to the conveying frame.

[0014] By adopting the above technical solution, the support block and the driving member cooperate to drive the pallet to be raised and lowered, and with the cooperation of the support component one, the pallet containing the cover to be processed is placed on the conveyor rack, thereby completing the automatic loading process to facilitate the processing of the cover.

[0015] The present invention is further configured as follows: the side support mechanism includes a side bracket and a driving member 2 for driving the side bracket to rise and fall, the two side brackets are symmetrically distributed on both sides of the conveying frame, the driving member 2 drives the side bracket to contact the edge of the pallet and then lifts the pallet vertically, and after the conveying frame moves, the side bracket supports the pallet to switch to an adjacent conveying station on the conveying frame.

[0016] By adopting the above technical solution, the pallet in the area to be processed or the area processed can be lifted upwards by cooperating with the second driving member and the side bracket, so as to facilitate switching the position of the pallet on the conveyor frame.

[0017] The present invention is further configured as follows: the second support component includes a mounting seat, a trapezoidal block and a rebound member for controlling the rebound of the trapezoidal block; the mounting seat is installed on the top of the feed frame; the bottom end of the trapezoidal block is rotatably installed on the inner side of the mounting seat; the bottom of the trapezoidal block is provided with an inclined surface extending toward the inner side of the feed frame and inclined upward; the two ends of the rebound member are respectively fixedly connected to the mounting seat and the trapezoidal block.

[0018] By adopting the above technical solution, the mounting seat, the trapezoidal block and the rebound member cooperate with each other, so that the pallet can be automatically supported after it moves to the top of the discharge frame, thereby improving the stacking efficiency of the pallet.

[0019] The present invention is further configured as follows: the jacking mechanism includes a jacking block and a driving member three for driving the jacking block to rise and fall; the driving member three is installed on the top of the workbench; after the driving member three drives the jacking block to pass through the through hole and contacts the bottom of the tray, the jacking block supports the tray to move upward from the top of the conveying rack to the top of the feed frame.

[0020] By adopting the above technical solution, the pallets in the stacking area can be lifted upward through the cooperation between the lifting block and the driving component three, and with the cooperation of the support component two, the pallet stacking work is completed to facilitate the batch transfer of the processed cover plates.

[0021] The present invention is further configured as follows: corner brackets are provided at the four corners of the discharge frame and the feed frame to prevent the pallet from tipping over; a rotatable movable frame is provided at the top of the corner bracket and on the side away from the conveying mechanism; the sliding connection of the movable frame has a plug-in part that is plugged in and cooperates with the discharge frame and the feed frame to limit the rotation of the movable frame.

[0022] By adopting the above technical solution, under the limitation of the plug-in parts, the corner brackets and the movable brackets are limited at the four corners of the tray to prevent the tray from tipping over. When the movable bracket rotates to the horizontal position, it is convenient to carry the tray.

[0023] The present invention is further configured as follows: Photoelectric sensors for monitoring the in-place state of the tray are provided inside the loading area, the area to be processed, the processed area, and the stacking area.

[0024] By adopting the above technical solution, the photoelectric sensors can be used to detect whether the transfer stations on the transfer rack are in the corresponding areas, which is convenient for accurately transferring the tray. The pressure sensors can monitor the number of cover plates in the tray, so as to facilitate the transfer mechanism to transfer the tray to different processing areas.

Detailed implementation manners

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Refer to Figures 1 - 8 , an automatic loading device for processing a heat dissipation fan cover plate disclosed by the present invention, includes a workbench 1 and a tray 2 for storing the cover plates. The workbench 1 is sequentially provided with a loading area 11, an area to be processed 12, a processed area 13 and a stacking area 14. The loading area 11 is used for storing a plurality of trays 2 loaded with cover plates to be processed. The manipulator picks up the cover plates on the tray 2 in the area to be processed 12 for processing. After the cover plates are processed, the manipulator places the cover plates on the tray 2 in the processed area 13. The stacking area 14 is used for stacking a plurality of trays 2 loaded with processed cover plates. The top of the workbench 1 is provided with a conveying mechanism 3 for gradually conveying the tray 2 from the loading area 11 to the stacking area 14. The conveying mechanism 3 can adopt a cyclic conveyor belt structure or a reciprocating moving bracket structure to facilitate automatic loading and stacking of the tray 2 during the processing; A loading rack 4 for storing the cover plates to be processed is provided in the loading area 11. A feeding frame 41 is provided on the top of the feeding rack 4 for the tray 2 to pass downward. A supporting assembly 42 is provided on the top of the feeding frame 41 to support the tray 2 to prevent multiple trays 2 from falling from the inside of the feeding frame 41. A feeding mechanism 5 is provided below the feeding frame 41 to support the tray 2 in ascending and descending. After the feeding mechanism 5 contacts the bottom of the tray 2, the tray 2 is supported and falls onto the conveying mechanism 3. A side support mechanism 6 is provided in both the processing area 12 and the processed area 13. The side support mechanism 6 contacts the edge of the tray 2 and lifts the tray 2 vertically, so that the tray 2 is separated from the conveying mechanism 3, so as to switch the position of the tray 2 on the conveying mechanism 3 after the conveying mechanism 3 moves. The stacking area 14 is provided with a stacking rack 7 for storing processed cover plates, and the top of the stacking rack 7 is provided with a feed frame 71 for the pallet 2 to pass upward, and the top of the feed frame 71 is provided with a support component 2 72 for supporting the pallet 2, and the top of the workbench 1 is provided with a lifting mechanism 8 for vertically lifting the pallet 2 to the top of the feed frame 71. The support component 2 72 collides with the pallet 2 lifted to the top of the feed frame 71, and the lifting mechanism 8 collides with the bottom of the pallet 2 and lifts the pallet 2 to the top of the feed frame 71.

[0037] During the specific implementation process, the loading area 11 stores the pallet 2 with the cover plate to be processed through the loading rack 4, and an empty pallet 2 is placed on the top of the conveying mechanism 3 in the processed area 13. When the cover plate to be processed is loaded, first, the empty pallet 2 in the processing area 12 is lifted up by the side support mechanism 6, and then the leftmost end of the conveying mechanism 3 is controlled to move to the loading area 11, and the discharge mechanism 5 is controlled to contact and support the bottom of the lowermost pallet 2. Then, the support component 42 is controlled to complete a telescopic movement. When the support component 42 contracts inward, the support component 42 is separated from the pallet 2, so that the discharge mechanism 5 drives the pallet 2 downward through the discharge frame 41 and is placed on the lowermost pallet. When the tray 2 passes through the discharge frame 41, the support assembly 42 extends outward and supports and fixes the remaining pallets 2, and the discharge mechanism 5 can bring the lowest pallet 2 to the leftmost end of the conveying mechanism 3. At the same time, the side support mechanism 6 puts the pallet 2 lifted up in the processing area 12 back on the top of the conveying mechanism 3. After that, the conveying mechanism 3 is controlled to transport the pallet 2 to one side of the stacking area 14, and brings the pallet 2 with the cover to be processed to the processing area 12, and brings the empty pallet 2 to the processed area 13. The robot picks up the cover on the pallet 2 in the processing area 12 for processing, and after the cover processing is completed, the processed cover is placed in the pallet 2 in the processing area 12.

[0038] When the trays 2 at the processed area 13 are filled with cover plates, the trays 2 at the area to be processed 12 are in an empty state. The conveying mechanism 3 conveys towards one side of the stacking area 14, and can carry the trays 2 filled with processed cover plates in the processed area 13 to the stacking area 14, and carry the trays 2 in an empty state at the area to be processed 12 to the processed area 13. Then, the trays 2 in the stacking area 14 are lifted upward by the lifting mechanism 8. During the lifting process, the trays 2 contact the second support assembly 72, which can cause the second support assembly 72 to elastically contract. When the trays 2 move above the feeding frame 71, the second support assembly 72 resets under the elastic action to support the trays 2, thus facilitating continuous stacking of the trays 2.

[0039] Refer to Figure 1 , a plurality of placement grooves 21 for placing the heat dissipation fan cover plates are provided on the top of the tray 2. The depth of the placement grooves 21 is greater than the thickness of the cover plate. When a plurality of trays 2 are stacked, it can prevent the upper trays 2 from squeezing the cover plates to avoid damage to the cover plates. In addition, the placement grooves 21 on the tray 2 are evenly distributed in a rectangular array, so as to facilitate the manipulator to pick up the cover plates in the tray 2 for processing according to the set program, or put the processed cover plates into the empty tray 2, improving the efficiency and accuracy of the manipulator picking up the cover plates.

[0040] Refer to Figure 2 and Figure 3 , the conveying mechanism 3 includes a sliding table 31, a conveying frame 32 and a driving device 33 for driving the conveying frame 32 to slide horizontally along the sliding table 31. The sliding table 31 is fixedly installed on the top of the workbench 1, and the conveying frame 32 is slidably matched with the sliding table 31 to gradually convey the tray 2 from the loading area 11 to the stacking area 14.

[0041] The driving device 33 can use an electric push rod to push the conveying frame 32 to slide horizontally along the sliding table 31, or use a servo motor and a ball screw to cooperate to drive the conveying frame 32 to move. Since the electric push rod, the servo motor and the ball screw are all prior arts and will not be elaborated here, it only needs to satisfy driving the conveying frame 32 to slide horizontally along the sliding table 31. In the specific implementation process, in order to improve the conveying accuracy of the conveying frame 32, the driving device 33 uses a ball screw rotatably installed on the sliding table 31 and a servo motor for driving the ball screw to rotate. The ball screw is threadedly connected with the conveying frame 32 inside the sliding table 31. The servo motor is installed on the top of the workbench 1, and the servo motor is coaxially driven with the ball screw to drive the ball screw to rotate, so that the ball screw drives the conveying frame 32 to move precisely along the sliding table 31, ensuring the stable transmission of the tray 2 to each working area and improving the overall processing efficiency and accuracy.

[0042] Refer to Figure 1 and Figure 3, there are three transfer stations 34 on the top of the transfer rack 32. In this embodiment, from left to right, they are the first station 341, the second station 342, and the third station 343. When the transfer rack 32 moves to the leftmost end of the sliding table 31, the three transfer stations 34 are successively located in the loading area 11, the area to be processed 12, and the processed area 13. When the transfer rack 32 moves to the rightmost end of the sliding table 31, the three transfer stations 34 are successively located in the area to be processed 12, the processed area 13, and the stacking area 14, so as to realize the orderly flow of the pallet 2 among the working areas, ensure the coherence and efficiency of the processing flow, reduce manual intervention at the same time, and improve the automation level.

[0043] Photoelectric sensors 15 for monitoring the in-place state of the pallet 2 are provided on the inner sides of the loading area 11, the area to be processed 12, the processed area 13, and the stacking area 14. Since the photoelectric sensors 15 are prior art, they will not be elaborated here. The adopted photoelectric sensors 15 can monitor the positions of the transfer stations 34 and the pallet 2. There are four photoelectric sensors 15, corresponding to the loading area 11, the area to be processed 12, the processed area 13, and the stacking area 14 respectively, and can be used to detect whether the transfer stations 34 on the transfer rack 32 are in the corresponding areas, and whether there is a pallet 2 stored in the transfer stations 34 in the corresponding areas. A controller for receiving and processing the induction signals sent by the photoelectric sensors 15 is provided in the driving device 33. The controller can control the driving device 33 to drive the transfer rack 32 to slide horizontally according to the induction signals, so as to ensure that each transfer station 34 and the pallet 2 can be accurately aligned after the transfer rack 32 moves.

[0044] A pressure sensor 37 for monitoring the number of cover plates in the pallet 2 is installed at the bottom of each transfer station 34. Since the pressure sensor 37 is prior art, it will not be elaborated here. The adopted pressure sensor 37 can monitor the weight on the pallet 2. Since the pallet 2 stores the cover plates according to a unified standard, whenever the manipulator picks up or places a cover plate, the monitoring data of the pressure sensor 37 will change according to the number of cover plates and send an induction signal to the controller in the driving device 33. The controller can control the driving device 33 to drive the transfer rack 32 to slide horizontally according to the induction signal. By using the pressure sensor 37 to monitor the number of cover plates on the pallet 2 in the area to be processed 12 and the processed area 13, it is convenient for the transfer mechanism 3 to transfer the pallet 2 to different processing areas.

[0045] In the further implementation process, limit plates 35 are fixed on the top of the transfer rack 32 and on both sides of the transfer stations 34 by bolts. The limit plates 35 are located on both sides of the pallet 2. When the transfer rack 32 slides along the sliding table 31 to transfer the pallet 2, the limit plates 35 can limit the lateral movement of the pallet 2, prevent the pallet 2 from shifting due to inertia after the transfer rack 32 stops, ensure the stability of the pallet 2 during the transfer process, and accurately position the pallet 2, facilitating the manipulator to accurately pick up or place the cover plates.

[0046] Referring to Figure 3 , a through hole 36 is provided at the end of the transfer rack 32 for the feeding mechanism 5 or the lifting mechanism 8 to pass through. The arrangement of the through hole 36 enables the output end of the feeding mechanism 5 or the lifting mechanism 8 to pass through the transfer rack 32 and contact the tray 2, so as to facilitate controlling the lifting of the tray 2 in the loading area 11 or the stacking area 14, thereby improving the loading and unloading efficiency of the tray 2.

[0047] Referring to Figure 1 and Figure 4 , there are multiple groups of the first support components 42, which are evenly installed on the top of the feeding frame 41. The first support components 42 include support blocks 421 and control components 422 for driving the support blocks 421 to move laterally. The control components 422 are installed on the top of the feeding frame 41, and the support blocks 421 are threadedly connected to the ends of the output shafts of the control components 422. In the specific implementation process, the control components 422 can adopt electric push rods, cylinders or solenoid valve structures. Electric push rods, cylinders or solenoid valves are all prior arts and will not be elaborated here. It is only necessary to make the control components 422 satisfy driving the support blocks 421 to approach or move away from the tray 2. When the control components 422 drive the support blocks 421 to approach the tray 2, they can support at the bottom of the tray 2, stack multiple groups of trays 2 on the top of the feeding frame 41. When the control components 422 drive the support blocks 421 to move away from the tray 2, the first support components 42 can control the lifting of the tray 2 to facilitate placing the cover plate to be processed on the transfer rack 32.

[0048] In the further implementation process, in order to facilitate the support of the tray 2 by the support blocks 421, a groove 22 matching the support blocks 421 is provided at the top edge of the tray 2. The top of the support blocks 421 is designed to be inclined. When the first support components 42 control the downward movement of the tray 2, the reset support blocks 421 can quickly insert into the grooves 22 on the lowermost tray 2 and support and fix the remaining trays 2, thereby ensuring the stability of the stacked trays 2, avoiding the risk of slipping, and improving the safety of the overall operation.

[0049] Referring to Figure 4 , there are multiple groups of the feeding mechanisms 5, which are evenly arranged inside the loading area 11 and can uniformly contact the bottom of the tray 2 to improve the stability of the tray 2. The feeding mechanism 5 includes support blocks 51 and a first driving component 52 for driving the support blocks 51 to lift. The first driving component 52 is installed on the top of the workbench. The first driving component 52 can adopt an electric push rod, a cylinder or a hydraulic cylinder. Since electric push rods, cylinders and hydraulic cylinders are all prior arts and will not be elaborated here, it is only necessary to make the first driving component 52 drive the support blocks 51 to lift through the output shaft.

[0050] When the tray 2 stored on the material discharging frame 41 needs to be placed on the conveying rack 32, the driving member 1 52 drives the supporting block 51 to pass through the through hole 36 and contact the bottom of the tray 2, and pushes the tray 2 upward to separate the tray 2 from the supporting block 421. Then, the control member 422 drives the supporting block 421 to perform a reciprocating motion. When the supporting block 421 is away from the tray 2, the driving member 1 52 drives the supporting block 51 to move downward continuously, and drives the tray 2 to move downward continuously. When the tray 2 moves downward, the reset The support block 421 can be inserted into the groove 22 of the lowest tray 2, and the lowest tray 2 is separated from the remaining trays 2 while supporting and fixing the remaining trays 2. Then, the driving member 52 drives the support block 51 to move downward continuously, and the tray 2 with the cover to be processed is placed on the work station 341 on the top of the conveying rack 32. After that, the driving member 52 drives the support block 51 downward away from the through hole 36 to facilitate the conveying rack 32 to bring the tray 2 on the work station 341 to the area to be processed 12.

[0051] Reference Figure 1 and Figure 2 The two sets of side support mechanisms 6 are respectively arranged in the to-be-processed area 12 and the processed area 13, and the side support mechanism 6 includes symmetrically distributed side brackets 61 and a second driving member 62 for driving the side brackets 61 to rise and fall. The second driving member 62 can adopt an electric push rod, a cylinder or a hydraulic cylinder. Since the electric push rod, the cylinder and the hydraulic cylinder are all existing technologies, they are not described here. It is only necessary to satisfy that the second driving member 62 drives the side bracket 61 to rise and fall through the output shaft. The two side brackets 61 are symmetrically distributed on both sides of the conveying rack 32. After the second driving member 62 drives the side bracket 61 to contact the edge of the pallet 2, the pallet 2 can be vertically lifted, so that the pallet 2 can be switched to an adjacent conveying station 34 after the conveying rack 32 moves.

[0052] When the workstation 1 341 of the conveyor rack 32 is located in the area to be processed 12, the driving member 2 62 and the side bracket 61 cooperate with each other to lift the tray 2 in the area to be processed 12 and the processed area 13, so that the tray 2 is separated from the conveyor rack 32. After that, the conveyor rack 32 is controlled to move to one side of the loading area 11, so that the workstation 1 341 of the conveyor rack 32 moves to the loading area 11. Then, the driving member 2 62 and the side bracket 61 drive the tray 2 to move downward, and the tray 2 in the area to be processed 12 is placed on the conveyor rack 3. 2, and place the pallet 2 in the processed area 13 on the workstation 2 342 of the conveyor rack 32, and then control the conveyor rack 32 to move to one side of the stacking area 14, so that the pallet 2 on the workstation 2 342 can be brought from the to-be-processed area 12 to the processed area 13, and the pallet 2 on the workstation 343 can be brought from the processed area 13 to the stacking area 14, thereby realizing continuous switching of the position of the pallet 2 and efficient circulation of the pallet 2, ensuring seamless connection of the production process and improving overall operating efficiency.

[0053] ReferenceFigure 2 , Figure 5 and Figure 6 , the second supporting component 72 has multiple groups and is evenly installed on the top of the feeding frame 71. The second supporting component 72 includes a mounting seat 721, a trapezoidal block 722, and a resilient member 723 for controlling the rebound of the trapezoidal block 722. The mounting seat 721 is fixed to the top of the feeding frame 71 by bolts. The bottom end of the trapezoidal block 722 is rotatably installed inside the mounting seat 721. The bottom of the trapezoidal block 722 is provided with an inclined surface that extends towards the inside of the feeding frame 71 and slopes upwards. The resilient member 723 is installed on the inner wall of the mounting seat 721, and both ends of the resilient member 723 are fixedly connected to the mounting seat 721 and the trapezoidal block 722 respectively.

[0054] In the specific implementation process, the resilient member 723 can be a metal spring, a composite spring, or an air spring. When the resilient member 723 is in the natural rebound state, the bottom of the trapezoidal block 722 abuts against the top of the feeding frame 71, making the top of the trapezoidal block 722 in a horizontal state to support and fix the pallet 2 on the feeding frame 71. Through the mutual cooperation of the mounting seat 721, the trapezoidal block 722, and the resilient member 723, the pallet 2 is automatically supported, and the structure is simple, which can effectively reduce the production cost.

[0055] When the lifting mechanism 8 jacks up the pallet 2 upwards, it can squeeze the inclined surface at the bottom of the trapezoidal block 722, causing the trapezoidal block 722 to gradually rotate to the outside of the feeding frame 71 on the mounting seat 721, so as to facilitate the pallet 2 to gradually move above the discharging frame 41. During the rotation of the trapezoidal block 722, the resilient member 723 will be gradually compressed. After the lifting mechanism 8 jacks up the pallet 2 above the discharging frame 41, under the elastic action of the resilient member 723, the trapezoidal block 722 will be reset to facilitate the trapezoidal block 722 to support the stacked pallets 2.

[0056] Referring to Figure 5 , the lifting mechanism 8 has multiple groups and is evenly distributed in the stacking area 14. During lifting, it can be in uniform contact with the bottom of the pallet 2 to improve the stability of the pallet 2. The lifting mechanism 8 includes a lifting block 81 and a third driving member 82 for driving the lifting block 81 to lift. The third driving member 82 can be an electric push rod, a cylinder, or a hydraulic cylinder. Since the electric push rod, the cylinder, and the hydraulic cylinder are all prior arts, no further description will be given here. It only needs to satisfy that the third driving member 82 drives the lifting block 81 to lift. The third driving member 82 is installed on the top of the workbench. The third driving member 82 drives the lifting block 81 to pass through the through hole 36 and abut against the bottom of the pallet 2 to lift the pallet 2 from the rightmost conveying station 34 to the top of the feeding frame 71 and stack the pallets 2.

[0057] When the driving member III 82 drives the lifting block 81 to move up and down, the lifting block 81 can pass through the through hole 36 on the conveying frame 32 and smoothly lift the pallet 2 on the third station 343 upward. During the lifting process, the pallet 2 pushes the trapezoidal block 722 to rotate. When the pallet 2 is lifted above the feeding frame 71, the trapezoidal block 722 quickly rebounds and resets under the action of the elastic member 723. Then, the driving member III 82 drives the lifting block 81 to gradually move downward and drives the pallet 2 to smoothly descend. When the bottom of the pallet 2 contacts the trapezoidal block 722, the trapezoidal block 722 supports the bottom of the pallet 2 and separates the pallet 2 from the lifting block 81, thus completing the stacking process of one pallet 2 and ensuring the stacking accuracy and stability of the pallet 2.

[0058] Referring to Figure 1 、 Figure 7 and Figure 8 Figure, at the four corners of the blanking frame 41 and the feeding frame 71, angle brackets 9 for preventing the pallet 2 from tipping over are welded and fixed. On the top of the angle bracket 9 and on the side away from the conveying mechanism 3, there is a rotatable movable frame 91, and a plug-in member 92 for restricting the rotation of the movable frame 91 is slidably connected to the movable frame 91.

[0059] In the specific implementation process, the movable frame 91 is rotatably connected to the angle bracket 9 through a rotating shaft. A sliding groove 93 is formed on the movable frame 91, and through the sliding groove 93, the plug-in member 92 slides along the outer wall of the movable frame 91. The plug-in member 92 adopts an angle plate structure with a plug block 94 at the bottom. Slots 95 adapted to the plug block 94 are formed on both the blanking frame 41 and the feeding frame 71. The plug block 94 at the bottom of the plug-in member 92 can be inserted into and cooperate with the slots 95 at the corresponding positions on the blanking frame 41 and the feeding frame 71 to restrict and fix the movable frame 91.

[0060] When the movable frame 91 is in the vertical state, the plug block 94 at the bottom of the plug-in member 92 is inserted into and cooperates with the corresponding slots 95 on the blanking frame 41 and the feeding frame 71, which can restrict and fix the movable frame 91, enable the movable frame 91 and the angle bracket 9 to cooperate with each other, and limit the four corners of the pallet 2 to prevent the pallet 2 from tipping over. When the plug block 94 is separated from the slot 95, the movable frame 91 can be rotated on the angle bracket 9, so as to adjust the movable frame 91 to the horizontal state for facilitating the handling of the pallet 2 above the blanking frame 41 or the feeding frame 71.

First, operate the driving device 33 to drive the transfer rack 32 to move towards one side of the loading area 11, so that the first station 341 of the transfer rack 32 moves below the loading frame 41. Then, control the operation of the first driving member 52 to drive the support block 51 to lift and lower, so that the support block 51 passes through the through hole 36 and abuts against the bottom of the tray 2 on the loading frame 41. Next, make the control member 422 drive the supporting block 421 away from the tray 2, make the first driving member 52 drive the support block 51 to move downward, and drive the tray 2 to gradually move downward. During the movement, make the control member 422 drive the supporting block 421 to reset and insert it into the groove 22, so that the supporting block 421 separates the lowermost tray 2 and supports and fixes the remaining trays 2. Finally, the first driving member 52 and the support block 51 cooperate with each other to gradually drive the tray 2 loaded with the cover plate to be processed onto the first station 341 of the transfer rack 32.

[0062] S2: Transfer of the cover plate to be processed. First, place a tray 2 in an empty tray state on the second station 342 of the transfer rack 32.

[0063] S3: Processing of the cover plate. First, make the manipulator pick up the cover plate in the tray 2 located in the processing area 12, put the cover plate into the machining center for processing, and then the manipulator puts the processed cover plate into the tray 2 in the processed area 13 until the tray 2 in the processed area 13 is full of processed cover plates. At this time, the tray 2 in the processing area 12 is in an empty tray state.

[0064] S4: Position switching of the tray 2. When the tray 2 in the processed area 13 is full of cover plates, operate the second driving member 62 in the processing area 12 and the processed area 13 to drive the side bracket 61 to move upward, so that the side bracket 61 lifts the tray 2 on the transfer rack 32. Then, drive the transfer rack 32 to move towards the loading area 11 through the driving device 33, so that the third station 343 of the transfer rack 32 moves into the processed area 13. Next, make the second driving member 62 drive the side bracket 61 to move downward, put the empty tray 2 in the processing area 12 onto the second station 342 of the transfer rack 32, and put the tray 2 full of processed cover plates in the processed area 13 onto the third station 343 of the transfer rack 32. Finally, place the tray 2 loaded with the cover plate to be processed onto the first station 341 of the transfer rack 32 according to the steps of S1.

[0065] S5: Stacking of the processed cover plates. First, according to the steps of S2, operate the driving device 33 to drive the conveying rack 32 to move towards the stacking area 14, and drive the pallet 2 on the third station 343 to the lower part of the feeding frame 71; then, operate the third driving member 82 to drive the lifting block 81 to move upward, so that the lifting block 81 continuously lifts the pallet 2 upward, and the pallet 2 presses the trapezoidal block 722; when the pallet 2 moves above the feeding frame 71, make the elastic member 723 push the trapezoidal block 722 to rebound and reset; then drive the third driving member 82 to drive the lifting block 81 to move downward, place the pallet 2 on the trapezoidal block 722, so that the trapezoidal block 722 stably supports the pallet 2, and separate the pallet 2 from the lifting block 81, thereby stacking the pallet 2 loaded with the processed cover plates.
