Description

TECHNICAL FIELD

[0002] In the automobile manufacturing industry, the production of automobile display screen back plates is a key link. The display screen back plate usually needs to go through punching and tapping machining processes to ensure that it can be accurately installed in the automobile interior and work normally. Punching is to use a punch or a punching machine to place the workpiece in the die, and then to apply impact force to the plate by a punch, so that the workpiece forms a hole under the action of the punch and the die. Tapping is to use a tapping tool (such as a tap) to process internal threads on the hole of the workpiece on the basis of the hole formed by punching or drilling. Combining the two processes together can reduce the clamping frequency of the workpiece and improve the production efficiency.

[0003] However, the existing production equipment has obvious deficiencies in this link. Since the automobile display screen back plates formed by stamping are usually transferred to the punching and tapping machine by a transfer frame, workers usually need to take out the back plates one by one from the transfer frame and then manually place them on the processing machine. This process is not only time-consuming and labor-intensive, but also the speed of stamping and tapping is very fast, and the efficiency of manual material taking operation is low, so the speed of the whole processing process is severely limited.

DETAILED DESCRIPTION

[0030] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood and to be put into practical use, the present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the present application is not limited to the specific embodiments disclosed below.

[0032] In actual use, it is found that the existing production equipment has obvious deficiencies in this link. Since the stamping formed automobile display screen back plate is usually moved to the punching and tapping machine by the transfer frame, the worker usually needs to take out the back plate one by one from the transfer frame and then manually place it on the processing machine. This process not only wastes time and effort, but also the stamping and tapping speed is very fast, but the efficiency of manual material taking operation is low, so the speed of the whole processing process is seriously limited, which not only increases the labor intensity of the workers, but also reduces the overall efficiency of the production line. In order to solve the above problems, the following structure is invented.

[0033] As Figures 1-11The illustrated automobile display screen backboard punching and tapping integrated machine, including rack 1, and punching mechanism 2 and tapping mechanism 3 arranged on rack 1, the rack 1 is provided with feeding rack 4, the feeding rack 4 is internally provided with transfer car 5, the transfer car 5 top end is fixedly connected with a pair of clamping groove plates 6 for limiting the position of backboard, the feeding rack 4 top end and the rack 1 top end are fixedly connected with connecting frame 7, and the connecting frame 7 is provided with feeding mechanism 8 for clamping the backboard and then transversely moving through the punching mechanism 2 and tapping mechanism 3, the punching mechanism 2 is mainly composed of punch, die and power system, the feeding mechanism 8 is mainly composed of clamp and transverse moving mechanism, which can clamp the side end of the backboard and drive the backboard to transversely move on the rack 1, so as to be processed one by one through the punching mechanism 2 and tapping mechanism 3;

[0034] When working, the feeding mechanism 8 clamps the backboard and moves it below the punching mechanism 2, then the punch is driven by the power system to move downward quickly, and the material on the backboard is punched into the required hole shape, the punching process is usually completed in an instant, relying on the high-speed impact force of the punch to make the material plastically deform and be punched out of the hole, the key of 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 drive the backboard to move, and the backboard is moved below the tapping mechanism 3, the core components of the tapping mechanism 3 are tap and main shaft, the tap is a tool with threads, used to machine internal threads in a hole, and the main shaft is responsible for driving the tap to rotate and providing appropriate feed force, in the tapping process, the tap rotates under the drive of the main shaft and gradually enters the pre-punched hole, forming threads by cutting material, the tapping mechanism 3 needs to accurately control the speed and feed amount of the tap to ensure the quality and consistency of the threads, and finally the processed backboard is removed from the rack 1 under the transmission of the feeding mechanism 8.

[0036] The pair of reset springs 17 are fixedly connected between the clamping plates 16, and the limiting blocks 18 are fixedly connected to the side of the clamping plates 16 close to each other. Through the arrangement of the limiting blocks 18, the limiting blocks 18 cannot move after being moved above the back plate, thereby ensuring the accuracy of the clamping position of the subsequent feeding mechanism 8. The bottom end of the insertion plate 14 close to each other is inclined, which facilitates the extrusion of the back plate by the inclined surface of the bottom end of the insertion plate 14 when the position of the back plate deviates, so that the back plate is extruded between the two insertion plates 14, thereby ensuring the normal operation of the subsequent work.

[0037] The clamping mechanism includes a pair of upper electric telescopic cylinders 19, which are fixedly connected to the top end of the turnover frame 13. The top groove 20 is arranged at the top end of the turnover frame 13, and the sliding groove is arranged at the bottom end of the top groove 20 relative to the position above the clamping plate 16. The extrusion blocks 21 are fixedly connected to the top end of the clamping plate 16 through the sliding groove. The top end of each pair of extrusion blocks 21 is inclined. The top plate 22 is longitudinally and 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 end of the top plate 22 through the bottom end of the top groove 20. The U-shaped extrusion blocks 23 are arranged on both sides of the bottom end of the top plate 22 relative to the position above each pair of extrusion blocks 21. The side close to the U-shaped extrusion blocks 23 is inclined. The inclined surface of the U-shaped extrusion blocks 23 is matched with the inclined surface of the extrusion blocks 21. The release mechanism for releasing the back plate one by one is also arranged.

[0038] The moving mechanism includes a rotary motor 24 fixedly connected to the side wall of the U-shaped frame 12. The output end of the rotary motor 24 is fixedly connected to the rotating end of the turnover frame 13 through the inner side of the U-shaped frame 12. The moving motor 25 is fixedly connected to the top end of the vertical frame 10. The lead screw 26 is rotatably connected to the inner side of the vertical frame 10. The lead screw 26 is threadedly connected to the inner side wall of the sliding block 11. The output end of the moving motor 25 is fixedly connected to the top end of the lead screw 26 through the inner top end of the vertical frame 10.

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

[0040] In the punching and tapping process of the automobile display screen backboard, first, the transfer trolley 5 is pushed into the feeding frame 4, then the moving motor 25 is controlled to start and drive the screw rod 26 to rotate, thereby driving the sliding block 11 connected by threads to move downward, at the same time, driving the U-shaped frame 12 and the turnover frame 13 to move downward, and driving the plug-in plates 14 to move downward, so that the plurality of plug-in plates 14 are inserted between the plurality of backboards on the transfer trolley 5, then the moving motor 25 is controlled to stop running (at this time, the limit block 18 moves to the position of contacting the top end of the backboard), and then the upper electric telescopic cylinder 19 is controlled to start and drive the top plate 22 to move downward, at the same time, driving the plurality of U-shaped extrusion blocks 23 to move downward, thereby pushing the inclined surface of the extrusion block 21 through the inclined surface of the U-shaped extrusion block 23, so that each pair of extrusion blocks 21 slides to the side of approaching, at the same time, driving the clamping plate 16 to slide in the telescopic groove 15 and compressing the return spring 17, so as to drive the clamping plate 16 to move to the middle, thereby achieving clamping of the backboard (at this time, the limit block 18 is combined together and is located above the backboard);

[0041] Then the moving motor 25 is controlled to reverse, the screw rod 26 is controlled to reverse, thereby driving the sliding block 11 to move upward, at the same time, driving the U-shaped frame 12, the turnover frame 13 and the plug-in plates 14 to move upward, and driving the clamped backboard to move upward, then after the bottom end of the backboard moves above the feeding frame 4, the moving motor 25 is controlled to stop running, and the rotating motor 24 is controlled to start and drive the turnover frame 13 to rotate inside the U-shaped frame 12, at the same time, driving the plug-in plates 14, the clamping plate 16 and the clamped backboard to overturn, so that the backboard is overturned by 90 degrees upward and is in a horizontal state, then the horizontal moving mechanism of the feeding mechanism 8 inserts the clamp into the lowermost backboard, and the clamp of the feeding mechanism 8 clamps the lowermost backboard;

[0042] Then the lower electric telescopic cylinder 28 is controlled to start and drive the connecting rod 30 and the triangular block 31 to move, at this time, the inclined surface of the triangular block 31 will extrude the round rod 34 beside the lowermost backboard to move (since the round rod 34 and the L-shaped plate 33 can only move horizontally in the moving groove 32, therefore, under the extrusion of the inclined surface of the triangular block 31, the round rod 34 and the L-shaped plate 33 will slide in the moving groove 32), at the same time, driving the U-shaped extrusion block 23 to move and compressing the upper spring 36, so as to make the U-shaped extrusion block 23 move away from the extrusion block 21, thereby releasing the extrusion of the extrusion block 21, then driving the clamping plate 16 to reset under the elastic force of the return spring 17, thereby automatically releasing the clamping of the lowermost backboard, at this time, the horizontal moving mechanism of the feeding mechanism 8 is controlled to start, thereby pulling away the backboard to below the punching mechanism 2 for punching treatment, in this process, the moving motor 25 is controlled to start and drive the turnover frame 13 and the backboard to move downward, thereby moving the backboard to the feeding position of the feeding mechanism 8;

[0043] Subsequently, when the backboard punching tapping is completed, and the clamp of the feeding mechanism 8 clamps the corresponding backboard, the lower electric telescopic cylinder 28 is controlled to continue to operate, and the above operation is repeated, so that multiple backboards can be processed (it should be noted that when all the backboards are processed, the other inclined surface of the triangular block 31 will extrude the circular rod 34, so that the circular rod 34 and the L-shaped plate 33 move, avoiding affecting the reset of the triangular block 31).

[0044] In summary, through the design of the above structure, multiple backboards placed on the transfer trolley 5 can be automatically extracted, and the extracted backboards are turned over by 90 degrees, and then the clamping of the backboards is released one by one through the releasing mechanism, and then the backboards are sent to the punching mechanism 2 and the tapping mechanism 3 below for processing through the feeding mechanism 8, realizing the automatic material taking function of the backboards on the transfer trolley 5, and multiple backboards can be extracted and turned over at the same time, reducing the running stroke of the device and improving the processing efficiency of the device.

[0045] Based on the above embodiment, it is found that if the position of the vertical frame 10 is fixed, the backboards at the same position on the transfer trolley 5 can be taken, which is more limited. In order to solve the above problem, the above structure is further improved.

[0046] The side wall of the sliding frame 9 is fixedly connected with a pair of horizontal moving electric telescopic cylinders 27, the output end of the horizontal moving electric telescopic cylinder 27 is fixedly connected to the side wall of the vertical frame 10 inside the sliding frame 9, and the vertical frame 10 is slidably connected to the inside of the sliding frame 9;

[0047] The inside of the feeding frame 4 is fixedly connected with a pair of positioning blocks 40 for limiting the position of the transfer trolley 5, a magnet 41 is fixedly connected between the rear of the positioning blocks 40, and the contact area between the rear of the transfer trolley 5 and the magnet 41 is made of iron material;

[0048] When the transfer trolley 5 is pushed into the feeding frame 4, the position of the transfer trolley 5 can be limited by the positioning block 40, and then when the transfer trolley 5 is completely pushed into the feeding frame 4, the magnet 41 will attract the transfer trolley 5, and then the position of the transfer trolley 5 is limited by the attraction force, so as to ensure that the transfer trolley 5 does not move randomly during the extraction of the backboard, affecting the stability during the feeding process;

[0049] Then after the first extraction of the backboard processing of the turnover frame 13, the horizontal moving electric telescopic cylinder 27 can be controlled to start driving the vertical frame 10 to slide in the sliding frame 9, so as to change the material taking position of the turnover frame 13, when reaching the other row of backboard, the horizontal moving electric telescopic cylinder 27 can be controlled to stop running, repeating the above operation, the backboard taking work of the transfer trolley 5, it needs to be explained that when the backboard is reversed to the horizontal state, the horizontal moving electric telescopic cylinder 27 needs to be controlled to push the vertical frame 10 to reset, to ensure that the feeding mechanism 8 can take material normally, so as to repeat until the backboard on the transfer trolley 5 is taken out, then the transfer trolley 5 full of backboard is pushed in.

[0050] In summary, through the design of the above structure, the backboard at different positions on the transfer trolley 5 can be automatically taken, and through the setting of the positioning block 40 and the magnet 41, the position of the transfer trolley 5 after being pushed into the feeding frame 4 can be limited, to ensure the stability in the subsequent taking process.

[0051] On the basis of the above embodiment, it is found that the above structure can realize the automatic taking of the backboard on the transfer trolley 5, but when the feeding mechanism 8 takes out the backboard on the turnover frame 13, the lowering of the turnover frame 13 needs to be operated, which is troublesome, in order to solve the above problem, the above structure is further improved.

[0052] The inside of the moving groove 32 is fixedly connected with a touch sensor 37, and the touch sensor 37 is electrically connected between the controller and the moving motor 25 through the wire, and the touch sensor 37 is electrically connected between the controller and the moving motor 25;

[0053] When the L-shaped plate 33 is driven to slide in the moving groove 32 by the lower electric telescopic cylinder 28 during the operation of the releasing mechanism, the L-shaped plate 33 will touch the touch sensor 37, and then the touch sensor 37 will transmit the signal to the controller, and the controller will control the moving motor 25 to start, drive the U-shaped frame 12 and the backboard to move downward, and automatically adjust the backboard feeding position (it needs to be explained that the delay time of the delay control of the moving motor 25 is the time of pulling out the backboard by the feeding mechanism 8, so as to avoid being hindered and affect the normal operation of the equipment, at the same time, the starting time of the controller controlling the moving motor 25 is fixed, which can drive the backboard to move equidistantly, and quickly move the backboard to the feeding position of the feeding mechanism 8);

[0054] A plurality of fixed sensors 38 are fixedly connected to the top end of the sliding frame 9, and a moving sensor 39 is fixedly connected to the outer wall of the moving motor 25, and the fixed sensor 38 and the moving sensor 39 are electrically connected between the controller, and the fixed sensor 38 and the moving sensor 39 are electrically connected between the controller and the horizontal moving electric telescopic cylinder 27;

[0055] When the horizontal moving electric telescopic cylinder 27 starts to adjust the position of the back plate to take the material, 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, then transmit to the controller, the controller controls the horizontal moving electric telescopic cylinder 27 to stop running (it is necessary to explain that the moving distance of the horizontal moving electric telescopic cylinder 27 on each trolley 5 is increased gradually, so when it runs for the second time, the second fixed sensor 38 is set by degree, and does not feedback the signal to the controller, when the moving sensor 39 moves to the side of the third fixed sensor 38, the signal is transmitted, and when the trolley 5 is replaced, 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 adopt an optical proximity switch, the working principle of which is based on the photoelectric effect, and the position of an object is detected by emitting and receiving light. The optical proximity switch is composed of an emitter, a receiver and a control circuit. When the light is reflected or blocked by an object, the receiver detects the change of the light, and the control circuit judges the position of the object according to the signal change of the receiver and outputs a corresponding electric signal. In the device, the fixed sensor 38 is installed at a fixed position of the device, and is used to detect the position of the moving sensor 39. When the moving sensor 39 moves to the vicinity of the fixed sensor 38, the fixed sensor 38 detects the presence of the moving sensor 39 and sends a signal. The signal is transmitted to the controller, and the controller controls the horizontal moving electric telescopic cylinder 27 to stop or continue running according to the preset program. This sensor has the advantages of fast response speed, high precision and non-contact detection, and is suitable for position detection in an automatic production line.

[0057] In summary, through the design of the above structure, the moving motor 25 can be automatically controlled to start driving the turnover frame 13 and the back plate to move downward after the back plate is released one by one, which can automatically run and further improve the convenience of the device. And through the setting of the fixed sensor 38 and the moving sensor 39, when the horizontal moving electric telescopic cylinder 27 starts to take the back plate on the trolley 5 at other positions, the vertical frame 10 can be accurately moved to the specified position.

[0058] The above shows and describes the basic principles, main features and advantages of the present application.

[0059] Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
