Description

Technical Field

[0001] This invention relates to the field of display screen processing technology, and in particular to an integrated punching and tapping machine for automotive display screen back panels. Background Technology

[0002] In the automotive manufacturing industry, the production of automotive display screen back panels is a crucial step. Display screen back panels typically require processing steps such as punching and tapping to ensure they can be accurately installed inside the car and function properly. Punching is done using a punch press or punching machine, where the workpiece is placed in a mold, and then the punch applies impact force to the sheet metal, causing the workpiece to form a hole under the action of the punch and mold. Tapping is done by using a tapping tool (such as a tap) to create internal threads in the holes formed by punching or drilling. Combining these two processes can reduce the number of workpiece clamping operations and improve production efficiency.

[0003] However, existing production equipment has significant shortcomings in this step. Since the stamped automotive display screen back panels are mostly transferred to the punching and tapping machine via a transfer rack, workers usually need to pull the back panels out of the transfer rack one by one and then manually place them on the processing machine. This process is not only time-consuming and labor-intensive, but also inefficient due to the low speed of manual material handling, which severely limits the speed of the entire processing. This not only increases the labor intensity of workers, but also reduces the overall efficiency of the production line.

[0004] Therefore, an integrated punching and tapping machine for automotive display screen back panels is proposed to solve the above problems. Summary of the Invention

[0010] In the above technical solution, a pair of horizontal electric telescopic cylinders are fixedly connected to the side wall of the sliding frame.

[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0032] In practical use, it was found that the existing production equipment has obvious shortcomings in this step. Since the stamped automotive display screen back panels are mostly transferred to the punching and tapping machine via a transfer rack, workers usually need to pull the back panels out of the transfer rack one by one and then manually place them on the processing machine. This process is not only time-consuming and labor-intensive, but also the efficiency of manual material handling is low despite the fast speed of stamping and tapping. As a result, the speed of the entire processing process is severely limited. This not only increases the labor intensity of workers, but also reduces the overall efficiency of the production line. To solve the above problems, the following structure was invented.

[0033] like Figures 1-11The illustrated automotive display screen back panel punching and tapping integrated machine includes a frame 1, and a punching mechanism 2 and a tapping mechanism 3 mounted on the frame 1. A loading rack 4 is provided next to the frame 1, and a transfer cart 5 is provided inside the loading rack 4. A pair of slot plates 6 for limiting the position of the back panel are fixedly connected to the top of the transfer cart 5. A connecting frame 7 is fixedly connected between the top of the loading rack 4 and the top of the frame 1, and the connecting frame 7 is provided with a loading mechanism 8 for clamping the back panel and then moving it laterally through the punching mechanism 2 and the tapping mechanism 3. The punching mechanism 2 mainly consists of a punch, a mold and a power system, and the loading mechanism 8 mainly consists of a clamp and a lateral movement mechanism. It can clamp the side of the back panel and drive the back panel to move laterally on the frame 1, so that it can be processed one by one through the punching mechanism 2 and the tapping mechanism 3.

[0034] During operation, the feeding mechanism 8 clamps the back plate and moves it below the punching mechanism 2. Then, driven by the power system, the punch moves rapidly downwards, punching the material on the back plate into the required hole shape. The punching process is usually completed in an instant. Relying on the high-speed impact force of the punch, the material undergoes plastic deformation and is punched out of the hole. The key to the punching mechanism 2 is to accurately control the position and force of the punch to ensure that the size and shape of the hole meet the design requirements. Then, the feeding mechanism 8 continues to move the back plate, moving it below the tapping mechanism 3. The core components of the tapping mechanism 3 are the tap and the spindle. The tap is a threaded tool used to process internal threads in the hole. The spindle is responsible for driving the tap to rotate and providing appropriate feed force. During the tapping process, the tap rotates under the drive of the spindle and gradually enters the pre-punched hole, forming threads by cutting the material. The tapping mechanism 3 needs to accurately control the tap's speed and feed rate to ensure the quality and consistency of the threads. Finally, the processed back plate is removed from the frame 1 by the conveyor of the feeding mechanism 8.

[0035] A sliding frame 9 is fixedly connected to the top of the feeding rack 4. A vertical frame 10 is provided inside the sliding frame 9. A slider 11 is slidably connected to the inside of the vertical frame 10. A U-shaped frame 12 is fixedly connected to the side wall of the slider 11. A flipping frame 13 is rotatably connected to the inside of the U-shaped frame 12. Several pairs of insert plates 14 are fixedly connected at equal intervals to the top of the flipping frame 13. A telescopic groove 15 is opened on the side of each pair of insert plates 14 that are close to each other. A clamping plate 16 is slidably connected to the inside of the telescopic groove 15. The flipping frame 13 is provided with a clamping mechanism for driving multiple clamping plates 16 to clamp the back plate. It is also provided with a moving mechanism for driving the flipping frame 13 to flip and move upward.

[0036] A pair of return springs 17 are fixedly connected between each clamping plate 16. A limit block 18 is fixedly connected to each clamping plate 16 on the side closest to each other. By setting the limit block 18, the limit block 18 can be moved above the back plate and cannot move, thereby ensuring the accuracy of the clamping position of the subsequent feeding mechanism 8. The bottom ends of the insert plates 14 on the side closest to each other are inclined, so that when the position of the back plate deviates, the back plate can be squeezed between the two insert plates 14 by the inclined surface of the bottom end of the insert plate 14, ensuring the normal operation of the subsequent work.

[0037] The clamping mechanism includes an upper electric telescopic cylinder 19, which is provided in pairs. The upper electric telescopic cylinders 19 are fixedly connected to the top of the flip frame 13. The top of the flip frame 13 is provided with a top groove 20. The bottom of the top groove 20 is provided with a sliding groove relative to the position above the clamping plate 16. The top of the clamping plate 16 is fixedly connected to the pressing block 21 through the sliding groove. Each pair of pressing blocks 21 is inclined on the side away from each other. The top plate 22 is longitudinally slidably connected to the inner side of the top groove 20. The output end of the upper electric telescopic cylinder 19 is fixedly connected to the bottom of the top plate 22 through the bottom of the top groove 20. U-shaped pressing blocks 23 are provided on both sides of the bottom of the top plate 22 relative to the position above each pair of pressing blocks 21. The U-shaped pressing blocks 23 are inclined on the side close to each other. The inclined surface of the U-shaped pressing block 23 is in contact with the inclined surface of the pressing block 21. A release mechanism for releasing the back plate clamping one by one is also provided.

[0038] The moving mechanism includes a rotary motor 24, which is fixedly connected to the side wall of the U-shaped frame 12. The output end of the rotary motor 24 passes through the inside of the U-shaped frame 12 and is fixedly connected to the rotating end of the flip frame 13. A moving motor 25 is fixedly connected to the top of the vertical frame 10. A lead screw 26 is rotatably connected to the inside of the vertical frame 10. The lead screw 26 is threaded through and connected to the inner side wall of the slider 11. The output end of the moving motor 25 passes through the top of the inner end of the vertical frame 10 and is fixedly connected to the top of the lead screw 26.

[0039] The release mechanism includes a lower electric telescopic cylinder 28, a U-shaped connecting plate 29 fixedly connected to the inner side of the top groove 20, the lower electric telescopic cylinder 28 fixedly connected to the side wall of the U-shaped connecting plate 29, the output end of the lower electric telescopic cylinder 28 passing through the inner side of the U-shaped connecting plate 29 and fixedly connected to a connecting rod 30, both ends of the connecting rod 30 are fixedly connected to triangular blocks 31 with inclined surfaces on both sides, the top of the top plate 22 is provided with a moving groove 32 at the position above the U-shaped extrusion block 23, the top of the U-shaped extrusion block 23 is fixedly connected to an L-shaped plate 33, and the L-shaped plates 33 are all laterally slidably connected to the inner side of the moving groove 32, the top of the L-shaped plates 33 is fixedly connected to a round rod 34, the bottom of the top plate 22 is fixedly connected to both sides of a side plate 35, and an upper spring 36 is fixedly connected between the side wall of the U-shaped extrusion block 23 and the side wall of the side plate 35.

[0040] During the punching and tapping process of the automotive display screen back panel, the transfer cart 5 is first pushed into the loading rack 4. Then, the moving motor 25 is started to drive the lead screw 26 to rotate, which in turn drives the threaded slider 11 to move downward. At the same time, the U-shaped frame 12 and the flip frame 13 move downward, and the insert plate 14 moves downward, so that multiple insert plates 14 are inserted between multiple back panels on the transfer cart 5. Then, the moving motor 25 is stopped (at this time, the limit block 18 moves to the position of contact with the top of the back panel). Then, the upper electric telescopic cylinder 19 is started to drive the top plate 22 to move downward, which in turn drives multiple U-shaped extrusion blocks 23 to move downward. Then, the inclined surface of the U-shaped extrusion block 23 pushes the inclined surface of the extrusion block 21, so that each pair of extrusion blocks 21 slides to the side closer to each other. At the same time, the clamping plate 16 slides in the telescopic groove 15 and compresses the return spring 17, thereby driving the clamping plate 16 to move towards the middle to achieve clamping of the back panel (at this time, the limit block 18 is combined together and is located above the back panel).

[0041] Then, the moving motor 25 can be reversed, and the lead screw 26 can be reversed, thereby driving the slider 11 to move upward. At the same time, the U-shaped frame 12, the flipping frame 13 and the insert plate 14 are moved upward, and the clamped back plate is also moved upward. After the bottom of the back plate moves above the loading rack 4, the moving motor 25 can be stopped, and the rotating motor 24 can be started to drive the flipping frame 13 to rotate inside the U-shaped frame 12. At the same time, the insert plate 14, the clamping plate 16 and the clamped back plate are flipped, so that the back plate is flipped upward 90 degrees and is in a horizontal state. Then, the horizontal movement mechanism of the loading mechanism 8 can be controlled to insert the clamp into the bottom back plate, and the clamp of the loading mechanism 8 can be controlled to clamp the bottom back plate.

[0042] Then, the electric telescopic cylinder 28 is started to drive the connecting rod 30 and the triangular block 31 to move. At this time, the inclined surface of the triangular block 31 will squeeze the round rod 34 next to the bottom back plate to move (since the round rod 34 and the L-shaped plate 33 can only move laterally in the moving groove 32, the round rod 34 and the L-shaped plate 33 will slide in the moving groove 32 under the squeezing of the inclined surface of the triangular block 31). At the same time, it drives the U-shaped extrusion block 23 to move and compress the upper spring 36, so that the U-shaped extrusion block 23 moves out from the side of the extrusion block 21, releasing the squeezing of the extrusion block 21. Then, under the elastic force of the return spring 17, the clamping plate 16 is pushed to reset, and the clamping of the bottom back plate is automatically released. At this time, the transverse movement mechanism of the feeding mechanism 8 can be started to pull the back plate away and pull it to the bottom of the punching mechanism 2 for punching. During this process, the moving motor 25 can be started to drive the flipping frame 13 and the back plate to move downward, moving the back plate to the feeding position of the feeding mechanism 8.

[0043] Subsequently, after the back plate is punched and tapped, and the clamp of the feeding mechanism 8 holds the corresponding back plate, the lower electric telescopic cylinder 28 can be controlled to continue running. Repeat the above operation, and so on, to process multiple back plates. (It should be noted that after all the back plates are processed, when the lower electric telescopic cylinder 28 is reset, the other inclined surface of the triangular block 31 will squeeze the round rod 34, causing the round rod 34 and the L-shaped plate 33 to move, so as to avoid affecting the reset of the triangular block 31).

[0044] In summary, through the design of the above structure, multiple back plates placed on the transfer cart 5 can be automatically extracted, then the extracted back plates can be rotated 90 degrees and placed horizontally. Subsequently, the clamping of the back plates can be released one by one by the release mechanism, and then the back plates can be sent one by one to the punching mechanism 2 and the tapping mechanism 3 for processing by the feeding mechanism 8. This realizes the automatic material picking function of the back plates on the transfer cart 5, and can simultaneously extract and rotate multiple back plates, reducing the running stroke of the device and improving the processing efficiency of the device.

[0045] Based on the above embodiments, it was found during use that if the position of the vertical frame 10 is fixed, it is possible to pick up the back panel at the same position on the transfer vehicle 5, which is rather limited. In order to solve the above problems, the above structure has been further improved.

[0046] A pair of horizontally moving electric telescopic cylinders 27 are fixedly connected to the side wall of the sliding frame 9. The output end of the horizontally moving electric telescopic cylinder 27 passes through the inside of the sliding frame 9 and is fixedly connected to the side wall of the vertical frame 10. The vertical frame 10 is horizontally slidably connected to the inside of the sliding frame 9.

[0047] The inner ends of the loading rack 4 are fixedly connected with positioning blocks 40 for limiting the position of the two sides of the transfer vehicle 5. Magnets 41 are fixedly connected between the rear of the positioning blocks 40, and the area of ​​the rear of the transfer vehicle 5 in contact with the magnets 41 is made of iron.

[0048] When the transfer cart 5 is pushed into the loading rack 4, the positioning block 40 can restrict the position of the transfer cart 5 on both sides. Then, when the transfer cart 5 is fully pushed into the loading rack 4, the magnet 41 will attract the transfer cart 5, thereby restricting the position of the transfer cart 5 through the attraction force, ensuring that the transfer cart 5 does not move at will during the back panel extraction process, which would affect the stability of the loading process.

[0049] After the first back panel is processed by the flipping frame 13, the horizontal electric telescopic cylinder 27 can be started to drive the vertical frame 10 to slide within the sliding frame 9, thereby changing the material picking position of the flipping frame 13. When it reaches the other row of back panels, the horizontal electric telescopic cylinder 27 can be stopped. The above operation is repeated to pick up the back panels on the transfer car 5. It should be noted that when the back panel is flipped to a horizontal state, the horizontal electric telescopic cylinder 27 needs to be controlled to push the vertical frame 10 back to its original position to ensure that the feeding mechanism 8 can pick up the material normally. This process is repeated until all the back panels on the transfer car 5 are picked up. Then the transfer car 5 can be pulled out forcefully and the transfer car 5 full of back panels can be pushed in.

[0050] In summary, the above-mentioned structure design enables automatic material retrieval from back panels at different positions on the transfer vehicle 5. Furthermore, the positioning block 40 and magnet 41 restrict the position of the transfer vehicle 5 after it is pushed into the loading rack 4, ensuring stability during subsequent material retrieval.

[0051] Based on the above embodiments, it was found during use that although the above structure can realize the automatic material picking of the back plate on the transfer vehicle 5, when the feeding mechanism 8 takes out the back plate on the flipping frame 13, it is still necessary to operate the lowering of the flipping frame 13, which is quite troublesome. In order to solve the above problems, the above structure has been further improved.

[0052] Touch sensors 37 are fixedly connected to the inner side of the moving slot 32, and the touch sensors 37 are electrically connected to the controller through wires, and the touch sensors 37 are electrically connected to the moving motor 25 through the controller.

[0053] During the operation of the release mechanism, when the L-shaped plate 33 is driven to slide in the moving groove 32 by the lower electric telescopic cylinder 28, the L-shaped plate 33 will touch the touch sensor 37. The touch sensor 37 will then transmit a signal to the controller. The controller will delay the start of the moving motor 25, drive the U-shaped frame 12 and the back plate to move down, and automatically adjust the loading position of the back plate. (It should be noted that the delay time of the moving motor 25 is the time when the loading mechanism 8 pulls out the back plate, so as to avoid obstruction and affect the normal operation of the equipment. At the same time, the start time of the moving motor 25 controlled by the controller is fixed, which can drive the back plate to move at an equal distance and quickly move the back plate to the loading position of the loading mechanism 8.)

[0054] Several fixed sensors 38 are fixedly connected at equal intervals at the top of the sliding frame 9. A moving sensor 39 is fixedly connected to the outer wall of the moving motor 25. Both the fixed sensors 38 and the moving sensors 39 are electrically connected to the controller. The fixed sensors 38 and the moving sensors 39 are also electrically connected to the transverse electric telescopic cylinder 27 through the controller.

[0055] When the transverse electric telescopic cylinder 27 starts adjusting the material picking position of the back plate, it will drive the vertical frame 10 and the moving motor 25 to move together, and drive the moving sensor 39 to move. When the moving sensor 39 moves to the side of the second fixed sensor 38, it will receive a signal and then transmit it to the controller. The controller will control the transverse electric telescopic cylinder 27 to stop running. (It should be noted that the starting movement distance of the transverse electric telescopic cylinder 27 on each transfer car 5 increases gradually. Therefore, during the second run, the second fixed sensor 38 does not feed back a signal to the controller through the level setting. When the moving sensor 39 moves to the side of the third fixed sensor 38, it transmits a signal. When the transfer car 5 is changed, the vertical frame 10 is reset and the program of the fixed sensor 38 is reset.)

[0056] The fixed sensor 38 and the moving sensor 39 employ photoelectric proximity switches. These sensors operate based on the photoelectric effect, detecting the position of an object by emitting and receiving light. A photoelectric proximity switch consists of a transmitter, a receiver, and a control circuit. The transmitter emits a beam of light; when the light is reflected or blocked by an object, the receiver detects the change in light. The control circuit determines the object's position based on the signal change from the receiver and outputs a corresponding electrical signal. In this device, the fixed sensor 38 is installed at a fixed position on the device to detect the position of the moving sensor 39. When the moving sensor 39 moves near the fixed sensor 38, the fixed sensor 38 detects its presence and sends a signal. This signal is transmitted to the controller, which controls the lateral electric telescopic cylinder 27 to stop or continue operating according to a preset program. This type of sensor has advantages such as fast response speed, high accuracy, and non-contact detection, making it suitable for position detection in automated production lines.

[0057] In summary, through the design of the above structure, after each backplate is released from clamping, the moving motor 25 can be automatically controlled to start and drive the flipping frame 13 and the backplate to move down, enabling automated operation and further improving the convenience of the device. Furthermore, by setting the fixed sensor 38 and the moving sensor 39, when the backplates in other positions on the transfer vehicle 5 are picked up, the horizontal electric telescopic cylinder 27 can be started to precisely move the vertical frame 10 to the designated position.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0059] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
