Description

Technical Field

[0001] The present invention relates to the technical field of chassis manufacturing, and in particular to an automated production line for chassis manufacturing. Background Art

[0002] The chassis is the carrier of most computer components. The main structure of the chassis is mainly made of chassis plates made of steel or aluminum-magnesium alloy, which are processed through stamping and bending processes;

[0003] When bending the chassis sheet required for the existing chassis processing, it is necessary to place it on a carrier so that the limiting protrusions on the carrier pass through the holes processed on the chassis sheet to position the chassis sheet, and then use a stamping device to bend the chassis sheet. This method requires operators to place the chassis sheets one by one. During this process, the operators are also required to align the holes on the chassis sheet with the limiting protrusions on the carrier and penetrate them, making the placement of the chassis sheet cumbersome. After the processing is completed, the operator needs to remove it and then place a new chassis sheet to be processed;

[0004] In addition, the conveyor line in the existing processing procedure needs to stop working when processing the chassis plate to provide time for the chassis plate processing, resulting in a low degree of automation in the chassis plate processing procedure and poor continuity of the processing procedure, resulting in an overall low processing efficiency of the chassis plate, which in turn affects the manufacturing efficiency of the chassis. Therefore, an automated production line for chassis manufacturing is proposed to solve the above problems. Summary of the invention

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, see Figures 1 to 7 , an automated production line for chassis manufacturing, comprising a conveyor belt 1 for conveying chassis plates (the conveyor belt 1 slowly and continuously conveys the conveyor chassis plates toward the direction of a U-shaped frame 7), a plurality of deviation correction adjustment mechanisms are evenly distributed on the surface of the conveyor belt 1, a driving rack plate 5 is arranged on one side of the conveyor belt 1, a U-shaped frame 7 is arranged above the conveyor belt 1 near the conveying end, a deflection magnet block 24 is arranged on one side of the conveyor belt 1 near the conveying end, fixed guide rails 11 fixed to the ground are arranged on both sides of the conveyor belt 1, and the bottom ends of both sides of the U-shaped frame 7 are slidably connected to the fixed guide rails 11 through bottom sliders 10;

[0034] It should be noted that: the correction and adjustment mechanism is used as a conveying carrier for the chassis plate. During the conveying process, the correction and adjustment mechanism can automatically adjust the angle of the chassis plate, so that the positioning column 16 automatically passes through the hole on the chassis plate, thereby realizing the automatic positioning function of the chassis plate. At the same time, during the continuous conveying process of the chassis plate, the lifting cylinder 8 on the U-shaped frame 7 cooperates with the center pressure block 801 to realize the bending function of the chassis plate, without the need for intermittent conveying of the conveyor belt 1, thereby improving the continuity of the bending processing of the chassis plate and further improving the processing efficiency of the chassis plate.

[0035] The correction adjustment mechanism includes a carrier box 2, a lifting plate 13 is slidably arranged on the inner side of the carrier box 2, the top of the lifting plate 13 is fixedly connected to a positioning column 16 adapted to the hole on the chassis plate, the bottom end of the lifting plate 13 is fixedly connected to a relatively arranged linkage toothed plate 18, the bottom end of the lifting plate 13 is connected to the inner bottom end of the carrier box 2 through a lifting spring 17, the two side walls of the carrier box 2 are provided with sliding openings 201 which are staggered up and down, the inner side of the sliding opening 201 is slidably arranged with a toggle plate 4, the top of the carrier box 2 is rotatably provided with a correction gear disk 12, and the top of the correction gear disk 12 is fixedly connected to a placement disk 3.

[0036] It should be noted that when the docking through hole 1201 on the deviation-correcting gear plate 12 is offset from the through hole 203 , the positioning column 16 , under the elastic force of the lifting spring 17 , passes through the through hole 203 and contacts the bottom end of the deviation-correcting gear plate 12 .

[0037] It should be noted that: when the correcting gear plate 12 drives the placement plate 3 to rotate (when the correcting gear plate 12 is in contact and meshing with the driving rack plate 5), until the docking through hole 1201 is aligned with the through hole 203, the lifting plate 13 moves up under the elastic force of the lifting spring 17, thereby driving the positioning column 16, the bending cylinder 15 and the bending plate 6 at its top to move up, so that the positioning column 16 passes through the docking through hole 1201 and the positioning hole 302, and is plugged into the hole on the chassis plate, thereby realizing the automatic positioning function of the chassis plate, without the need for manual alignment by the operator, and significantly improving the placement and positioning efficiency of the chassis plate.

[0038] The interior of the carrier box 2 is provided with a linkage assembly for controlling the telescopic movement of the toggle plates 4 on both sides. Further, the linkage assembly includes a linkage gear column 20 rotatably arranged on the inner wall of the carrier box 2 and a driven toothed plate 19 fixedly connected to one end of the toggle plate 4. The toothed plate surfaces of the driven toothed plates 19 on both sides are arranged facing each other and meshing with the linkage gear column 20. The inner bottom end of the carrier box 2 is provided with a helical gear assembly for limiting the unidirectional rotation of the linkage gear column 20.

[0039] The helical gear assembly includes a fixed shell 26 fixedly connected to the inner bottom end of the carrier box 2, and a limiting helical gear 25 meshing with the linkage gear column 20 is slidably provided on the inner side of the fixed shell 26, and a limiting spring is fixedly connected between the bottom end of the limiting helical gear 25 and the inner bottom end of the fixed shell 26.

[0040] It should be noted that: when the lifting plate 13 moves upward, it will drive the linkage tooth plate 18 set at its bottom end to move upward, and the upward movement of the linkage tooth plate 18 will drive the linkage gear column 20 meshing with it to rotate, and the rotation of the linkage gear column 20 drives the driven tooth plate 19 meshing with it to move, and the driven tooth plate 19 drives the toggle plate 4 fixed at one end to move, so that the toggle plate 4 is extended, ensuring that the deviation correction adjustment mechanism can use the toggle plate 4 to drive the U-shaped frame 7 to move synchronously during the movement of the conveyor belt 1 (in this process, the bottom sliders 10 at the bottom ends of both sides of the U-shaped frame 7 will stretch the reset spring 14), ensuring that the chassis plate can be bent during continuous transportation.

[0041] It is worth noting that: an inclined arc surface is provided on one side of the top of the limiting bevel tooth 25. When the lifting plate 13 moves upward, the linkage gear column 20 rotates clockwise, and the teeth on its surface squeeze the arc surface of the limiting bevel tooth 25, so that the limiting bevel tooth 25 moves downward, ensuring that the linkage gear column 20 can rotate smoothly.

[0042] When the output end of the bending cylinder 15 drives the bending plate 6 to move upward to bend the chassis plate, the bending cylinder 15 will have a downward pushing force on the lifting plate 13. At this time, the lifting plate 13 drives the linkage gear plate 18 to move downward, thereby making the linkage gear column 20 tend to rotate counterclockwise. When the linkage gear column 20 rotates counterclockwise, the teeth on its surface will be stuck by the limiting bevel teeth 25, so that it cannot rotate, thereby ensuring that the lifting plate 13 will not move downward, so that the bending cylinder 15 can drive the bending plate 6 to realize the bending function of the chassis plate.

[0043] Furthermore, a through hole 203 aligned with the positioning column 16 is formed at the top of the carrier box 2 , and a bending cylinder 15 arranged opposite to it is installed at the top of the lifting plate 13 , and the output end of the bending cylinder 15 is fixedly connected to the bending plate 6 .

[0044] Furthermore, a strip opening 202 aligned with the bending plate 6 is provided at the top of the carrier box 2. The setting of the strip opening 202 allows the bending plate 6 to pass through the top of the carrier box 2, thereby facilitating the bending plate 6 to pass through the bending opening 301, thereby realizing the bending function of the chassis plate. A docking through hole 1201 aligned with the through hole 203 is provided inside the correction gear plate 12. The setting of the docking through hole 1201 allows the positioning column 16 to pass through the docking through hole 1201 and the positioning hole 302, thereby realizing the function of automatically interlacing with the holes on the chassis plate.

[0045] Furthermore, a positioning hole 302 aligned with the docking through hole 1201 is opened inside the placement tray 3, a bending opening 301 aligned with the strip opening 202 is opened inside the placement tray 3, and a pressure sensor is installed at the center of the inner bottom end of the placement tray 3.

[0046] It is worth noting that a controller is installed inside the carrier box 2 , and the controller establishes an information transmission connection with the bending cylinder 15 , the pressure sensor, the opposing photoelectric sensor 9 and the lifting cylinder 8 .

[0047] It should be noted that: due to the setting of the pressure sensor, when the central pressure block 801 presses down the chassis plate, the pressure sensor receives pressure and feeds back to the controller. The controller controls the bending cylinder 15 to work, so that the output end of the bending cylinder 15 extends and drives the bending plate 6 to move upward, so that the bending plate 6 passes through the bending opening 301, thereby realizing the bending function of the chassis plate.

[0048] Furthermore, a lifting cylinder 8 is installed on the top of the U-shaped frame 7 , and the output shaft of the lifting cylinder 8 is fixedly connected to a central pressure block 801 . The inner wall of the U-shaped frame 7 is provided with a corresponding photoelectric sensor 9 .

[0049] It should be noted that: when the carrier box 2 moves to the bottom of the U-shaped frame 7, at this time, the toggle block contacts the U-shaped frame 7, and the placement plate 3 blocks the signal transmission between the opposing photoelectric sensor 9. The opposing photoelectric sensor 9 feeds back to the controller, and the controller controls the lifting cylinder 8 to work. The lifting cylinder 8 drives the central pressure block 801 connected to its output end to complete a lifting action. The downward movement of the central pressure block 801 will press down the chassis plate to ensure the stability of the chassis plate during the bending process. After the chassis plate completes the bending operation, the lifting cylinder 8 controls the central pressure block 801 to reset. After the central pressure block 801 is reset, the central pressure block 801 no longer presses down the chassis plate. At this time, the pressure sensor on the inside of the placement plate 3 no longer receives pressure. At this time, the pressure sensor feeds back to the controller, and the controller controls the bending cylinder 15 to drive the bending plate 6 to reset.

[0050] Furthermore, the side wall of the driving rack plate 5 is provided with evenly arranged telescopic grooves, in which telescopic teeth 502 are slidably arranged, and the telescopic teeth 502 are fixedly connected to the inner wall of the telescopic groove through a resistance spring 501. Furthermore, one end of the telescopic tooth 502 is provided with an arc-shaped inclined surface.

[0051] It should be noted that: when the positioning column 16 has completed the alignment and insertion operation with the hole on the chassis plate, the correcting gear plate 12 no longer rotates under the limiting action of the positioning column 16. If at this time, the correcting gear plate 12 is still engaged with the driving rack plate 5, the teeth on the correcting gear plate 12 will squeeze the arc-shaped inclined surface of the telescopic teeth 502 on the driving rack plate 5, thereby squeezing the telescopic teeth 502 to the inside of the telescopic groove, ensuring that the correcting gear plate 12 can continue to move horizontally along the driving rack plate 5.

[0052] Furthermore, an electromagnet 21 is installed between the fixed guide rails 11 , and an L-shaped rod is fixedly connected to one end of the fixed guide rail 11 .

[0053] It should be noted that the magnetic attraction force generated by the electromagnet 21 on the magnetic attraction lifting plate 13 is much greater than the elastic force generated by the lifting spring 17. When the carrier box 2 moves above the electromagnet 21, the electromagnet 21 will first magnetically attract the limiting helical teeth 25, so that the limiting helical teeth 25 are separated from the teeth on the surface of the linkage gear column 20, and the limiting of the linkage gear column 20 is released, so that the linkage gear column 20 can rotate counterclockwise, and then the lifting plate 13 moves downward under the action of the magnetic attraction force of the electromagnet 21, and drives the positioning column 16 arranged thereon to move downward, so that the positioning column 16 is separated from the hole on the chassis plate, and at the same time, the positioning column 16 is separated from the docking through hole 1201 on the deviation correction gear plate 12, and at this time the deviation correction gear plate 12 can drive the placement plate 3 to rotate automatically;

[0054] Furthermore, a buffer magnet block 22 is installed on the inner wall of the fixed guide rail 11 , a sponge column 23 is fixedly connected to one side wall of the buffer magnet block 22 , and a return spring 14 is fixedly connected between the buffer magnet block 22 and the bottom slider 10 .

[0055] It should be noted that when the lifting plate 13 moves down and resets, it will drive the linkage toothed plate 18 set at its bottom end to move down, and the linkage toothed plate 18 drives the linkage gear column 20 meshing with it to rotate, and the linkage gear column 20 drives the driven toothed plate 19 meshing with it to move, and the driven toothed plate 19 drives the toggle plate 4 to reset and separate from the U-shaped frame 7. At this time, after the U-shaped frame 7 has no thrust from the toggle plate 4, it resets under the pulling force of the reset spring 14. During the reset process, the bottom sliders 10 at the bottom ends of both sides of the U-shaped frame 7 will first hit the sponge column 23 to play a preliminary buffering role. During the rebound process, the magnetic attraction between the buffer magnet block 22 and the bottom slider 10 can play a resistance role in the rebound, and then play a further buffering role, so that the U-shaped frame 7 can quickly stop, which is convenient for the bending process of the next chassis plate.

[0056] When the present invention is used, a worker is required to place the chassis plate to be bent on the placement tray 3, and the chassis plate is slowly conveyed on the placement tray 3 along the conveyor belt 1;

[0057] During the conveying process, when the deflection-correcting gear plate 12 at the bottom of the placement plate 3 begins to contact and mesh with the driving rack plate 5, the deflection-correcting gear plate 12 rolls along the driving rack plate 5 and drives the placement plate 3 to rotate, and the placement plate 3 drives the chassis plate inside it to rotate. During the rotation process, when the docking through hole 1201 on the deflection-correcting gear plate 12 is aligned with the through hole 203 at the top of the carrier box 2, under the elastic force of the jacking spring 17, the lifting plate 13 moves up, and then drives the positioning column 16, the bending cylinder 15 and the bending plate 6 at the top thereof to move up, so that the positioning column 16 passes through the docking through hole 1201 and the positioning hole 302 in turn, and is plugged into the hole on the chassis plate, thereby realizing the automatic positioning function of the chassis plate, without the need for manual alignment by the operator, and significantly improving the placement and positioning efficiency of the chassis plate;

[0058] During the upward movement of the lifting plate 13, the lifting plate 13 drives the linkage toothed plate 18 at its bottom to move upward, and the linkage gear column 20 meshed with the linkage toothed plate 18 rotates clockwise (refer to Figure 3 ), the linkage gear column 20 drives the driven gear plate 19 meshing therewith to move, and the driven gear plate 19 drives the toggle plate 4 to move, so that the toggle plate 4 is extended, so that the toggle plate 4 can push the U-shaped frame 7 to move synchronously;

[0059] When the positioning column 16 has completed the alignment and insertion operation with the hole on the chassis plate, the correcting gear plate 12 no longer rotates under the limiting action of the positioning column 16. If at this time, the correcting gear plate 12 is still engaged with the driving rack plate 5, the teeth on the correcting gear plate 12 will squeeze the arc-shaped inclined surface of the telescopic teeth 502 on the driving rack plate 5, thereby squeezing the telescopic teeth 502 to the inside of the telescopic groove, so that it is out of engagement with the correcting gear plate 12, ensuring that the correcting gear plate 12 can continue to move horizontally along the driving rack plate 5;

[0060] Under the continuous conveying action of the conveyor belt 1, the carrier box 2 drives the toggle plate 4 to move continuously. When the toggle plate 4 contacts the U-shaped frame 7, the toggle plate 4 will drive the U-shaped frame 7 to move synchronously. In this process, the bottom sliders 10 at the bottom ends of both sides of the U-shaped frame 7 will stretch the reset springs 14;

[0061] When the carrier box 2 moves to the bottom of the U-shaped frame 7, the placement plate 3 will block the signal transmission between the opposing photoelectric sensors 9, and the opposing photoelectric sensors 9 will give feedback to the controller. The controller controls the lifting cylinder 8 to work, and the lifting cylinder 8 drives the central pressure block 801 at its output end to move downward. The central pressure block 801 moves downward and presses down the chassis plate. At this time, the pressure sensor on the inner side of the placement plate 3 senses the pressure and gives feedback to the controller. The controller controls the bending cylinder 15 to work, and the bending cylinder 15 drives the bending plate 6 at its output end to move upward. The bending plate 6 passes through the bending opening 301 on the placement plate 3 to bend the chassis plate.

[0062] After the bending function of the chassis plate is completed, the lifting cylinder 8 drives the central pressing block 801 to reset. After the central pressing block 801 is reset, the central pressing block 801 no longer presses down the chassis plate. At this time, the pressure sensor on the inner side of the placement plate 3 no longer receives pressure. At this time, the pressure sensor feeds back to the controller, and the controller controls the bending cylinder 15 to drive the bending plate 6 to reset.

[0063] When the carrier box 2 moves to above the electromagnet 21, the electromagnet 21 will magnetically attract the lifting plate 13, causing the lifting plate 13 to move downward, and drive the positioning column 16 set thereon to move downward, so that the positioning column 16 is separated from the hole on the chassis plate, and at the same time, the positioning column 16 is separated from the docking through hole 1201 on the deviation correction gear plate 12, and at this time, the deviation correction gear plate 12 can drive the placement plate 3 to rotate automatically;

[0064] When the lifting plate 13 moves down and resets, it will drive the linkage toothed plate 18 set at its bottom end to move down, and the linkage toothed plate 18 drives the linkage gear column 20 meshing with it to rotate, and the linkage gear column 20 drives the driven toothed plate 19 meshing with it to move, and the driven toothed plate 19 drives the toggle plate 4 to reset and separate from the U-shaped frame 7. At this time, after the U-shaped frame 7 has no thrust from the toggle plate 4, it resets under the pulling force of the reset spring 14. During the reset process, the bottom sliders 10 at the bottom ends of both sides of the U-shaped frame 7 will first hit the sponge column 23 to play a preliminary buffering role. During the rebound process, the magnetic attraction between the buffer magnet block 22 and the bottom slider 10 can play a resistance role in the rebound, and then play a further buffering role, so that the U-shaped frame 7 can quickly stop, which is convenient for bending the next chassis plate.

[0065] When the carrier box 2 moves to above the electromagnet 21, the placement plate 3 moves to the deflection magnet block 24. When the positioning column 16 is separated from the hole on the chassis plate, the deflection magnet block 24 will magnetically attract the placement plate 3, so that the placement plate 3 drives the correcting gear plate 12 to rotate a certain angle, so that the docking through-hole 1201 on the correcting gear plate 12 is staggered with the through-hole 203 at the top of the carrier box 2, to avoid the positioning column 16 being plugged into the hole on the chassis plate again under the action of the lifting spring 17 when the carrier box 2 and the electromagnet 21 are staggered. When the carrier box 2 carries the placement plate 3 to move to the bottom of the conveyor belt 1, the bent chassis plate automatically falls off the placement plate 3 under the action of gravity.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
