Description

Technical Field

[0001] This invention relates to the field of television frame manufacturing technology, specifically to an automatic stamping device for television frames. Background Technology

[0002] The automatic stamping equipment for TV frames is a highly efficient and precise automated device used for the production and processing of TV frames. This equipment typically consists of a frame, molds, a punch press, a feeding conveyor, an unloading conveyor, as well as auxiliary robotic arms and a material transfer module. The material transfer module is used to transfer the TV frame to achieve multiple stamping operations. The material transfer module is equipped with multiple vacuum suction cups for adsorbing the TV frame.

[0003] CN116551406B discloses a processing equipment for photovoltaic frames. However, in the existing automatic stamping equipment for TV frames, the material of the TV frame is subjected to external force and undergoes plastic deformation during the stamping process. This deformation may lead to stress concentration and uneven distribution. Specifically, bending and stretching processes during stamping will generate internal stress in the material, thus affecting the stamping quality. At the same time, burrs and folds in the punched holes after stamping will also affect the stamping quality. Furthermore, during transfer, the vacuum suction cup may not adhere tightly, causing it to fall off during the transfer process, which will also affect the stamping quality. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing an automatic TV bezel stamping device. In existing automatic TV bezel stamping devices, the material of the TV bezel undergoes plastic deformation under external force during the stamping process. This deformation can lead to stress concentration and uneven distribution. Specifically, bending and stretching processes during stamping generate internal stress in the material, affecting the stamping quality. Furthermore, burrs and flaking after stamping also affect the quality. Additionally, during transfer, the vacuum suction cup may not hold the bezel firmly, causing it to fall during transfer, further impacting the stamping quality.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An automatic stamping device for TV bezels includes multiple stamping modules and material transfer modules. Each material transfer module includes a moving plate. Two symmetrically arranged mounting plates are fixedly connected to the side wall of the moving plate, and multiple pneumatic suction heads are fixedly connected to the bottom of the mounting plates. A first lifting plate is connected to the bottom of each mounting plate through a first reset mechanism. Multiple arrayed through holes are opened on the top of the first lifting plate. The movement of the first lifting plate is driven by a pushing mechanism. The pneumatic suction heads are inserted into the through holes. Multiple arrayed moving rods are inserted into the top of the first lifting plate. The moving rods are connected to the top of the first lifting plate through a second reset mechanism. Ball bearings are provided at the bottom of the moving rods. The rotation of the moving rods is driven by a driving mechanism. Multiple mounting grooves are opened on the side wall of the moving rods. A grinding block is connected to each mounting groove through a telescopic mechanism. The grinding block includes an inclined surface. A detection mechanism for detecting the movement of the moving rods is provided above the first lifting plate.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the first reset mechanism includes two symmetrically arranged first sleeves fixedly connected to the top of the first lifting plate, and a first sleeve rod is inserted into each first sleeve. The upper end of the first sleeve rod is fixed to the bottom of the mounting plate, and a first spring is sleeved on the side wall of each first sleeve.

[0008] The beneficial effect of adopting the above-mentioned further solution is that it guides and resets the movement of the first lifting plate.

[0009] Furthermore, the pushing mechanism includes an L-shaped plate fixedly connected to the side wall of the mounting plate, and a motor is fixedly connected to the side wall of the L-shaped plate. A cam is fixedly connected to the output end of the motor, and the cam slides on the top of the first lifting plate.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when the motor is started, the rotation of the motor drives the rotation of the cam. When the tip of the cam abuts against the top of the first lifting plate, it can push the first lifting plate to move downward.

[0011] Furthermore, the second reset mechanism includes a fixed column fixedly connected to the upper end of the moving rod, and a second spring is sleeved on the side wall of the moving rod. A rotating ring is fixedly connected to the lower end of the second spring, and the rotating ring is rotatably connected to the top of the first lifting plate. The upper end of the second spring is fixed to the bottom of the fixed column.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it guides and resets the movement of the moving rod.

[0013] Furthermore, the driving mechanism includes a spiral groove formed on the side wall of the fixed column, and the bottom of the mounting plate is connected to a plurality of arrayed push pins through the mounting mechanism, the push pins being inserted into the spiral groove.

[0014] The beneficial effect of adopting the above-mentioned further solution is that when the first lifting plate moves downward, the push pin can slide in the spiral groove, thereby pushing the fixed column to rotate, which in turn drives the moving rod and the grinding block to rotate.

[0015] Furthermore, the mounting mechanism includes multiple arrayed fixing plates fixedly connected to the bottom of the mounting plate, and multiple arrayed mounting blocks fixedly connected to the bottom of each fixing plate, with push pins fixed to the side walls of the mounting blocks.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it enables the installation and fixation of the push pin.

[0017] Furthermore, the telescopic mechanism includes two symmetrically arranged second sleeves fixedly connected to the side walls of each grinding block, and a second sleeve rod is inserted into each second sleeve. The other end of the second sleeve rod is fixed to the side wall of the mounting groove, and a third spring is sleeved on the side wall of each second sleeve.

[0018] The beneficial effect of adopting the above-mentioned further solution is that when the inclined surface abuts against the top of the punch, it can push the grinding block to slide into the mounting groove. At the same time, the third spring is compressed, so that the grinding block can move into the punch and abut against the hole wall.

[0019] Furthermore, the detection mechanism includes a second lifting plate, which is connected to the side wall of the fixed plate via a guide mechanism. The side wall of the second lifting plate is fixedly connected with a plurality of arrayed blocks, which abut against the top of the fixed column. The movement of the second lifting plate is detected by a detection component.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, after the vibration is completed, the motor is started, so that the tip of the cam rotates to a vertically upward state. At this time, the first lifting plate can move upward and reset under the action of the first spring. At the same time, it drives multiple moving rods to move downward. Then, when the pneumatic suction head comes into contact with the top of the TV frame, it can adsorb it. After adsorption is completed, the TV frame is lifted a little distance, and the motor is started again, so that the tip of the cam comes into contact with the top of the first lifting plate, thereby pushing the first lifting plate to move downward and driving the moving rods to move downward. When the ball comes into contact with the top of the TV frame, it can push the moving rods and the fixed column to move upward. At the same time, the second spring is compressed, and the second lifting plate is driven to move upward through the stop block. If the pneumatic suction head is loose during adsorption, the TV frame can be pushed away from the pneumatic suction head under the pushing action of the moving rod. At this time, the moving rod can move downward and reset under the action of the second spring. At this time, under the action of gravity, the second lifting plate can move downward and be detected by the detection component.

[0021] Furthermore, the guiding mechanism includes two symmetrically arranged T-shaped guide rods fixedly connected to the top of the second lifting plate. The side walls of the T-shaped guide rods are fitted with connecting plates, and the connecting plates are fixed to the side walls of the fixed plate.

[0022] The beneficial effect of adopting the above-mentioned further solution is that it guides and limits the movement of the second lifting plate.

[0023] Furthermore, the detection component includes a sensing block fixedly connected to the top of the second lifting plate, and a proximity switch fixedly connected to the bottom of the connecting plate.

[0024] The beneficial effect of adopting the above-mentioned further solution is that when the moving rod and the fixed column move upward, the second lifting plate moves upward through the stop block. The proximity switch detects the sensing block. If the pneumatic suction head is loose during adsorption, the second lifting plate and the sensing block can move downward. When the proximity switch cannot detect the sensing block, an alarm operation is performed.

[0025] The beneficial effects of this invention are:

[0026] 1) By setting up a first reset mechanism and a pushing mechanism, after each stamping is completed, the material transfer module drives the moving plate and the mounting plate to move, and moves the first lifting plate to the top of the TV frame. Then, the motor is started, and the rotation of the motor drives the rotation of the cam. When the tip of the cam abuts against the top of the first lifting plate, it can push the first lifting plate to move downward. At the same time, the first spring is compressed. When the tip of the cam passes the top of the first lifting plate, the first lifting plate can move downward to reset under the action of the first spring. This process is repeated, so that the first lifting plate can move up and down repeatedly. When the first lifting plate moves downward, it can drive multiple moving rods to move downward through the second reset mechanism. When the ball abuts against the top of the TV frame, the second spring can be stretched. When the first lifting plate moves upward, it can drive multiple moving rods to move upward to reset through the second reset mechanism. This process is repeated, so that the ball can reciprocate to knock and vibrate the stamped TV frame, which helps to remove internal stress and ensure the quality of stamping.

[0027] 2) By setting up a drive mechanism, when the first lifting plate moves downward, the second reset mechanism drives multiple moving rods to move downward. When the moving rods are aligned with the punch hole, they can be inserted into the punch hole. When the inclined surface abuts against the top of the punch hole, it can push the grinding block to slide into the mounting groove. At the same time, the third spring is compressed, allowing the grinding block to move into the punch hole and abut against the hole wall. Meanwhile, when the first lifting plate moves downward, the push pin can slide in the spiral groove, thereby pushing the fixed column to rotate, which in turn drives the moving rods and the grinding block to rotate. This allows for automatic grinding of the inner wall of the punch hole, making it more convenient and faster to use, and ensuring the quality of stamping.

[0028] 3) By setting up a detection mechanism, after vibration is complete, the motor is started, causing the tip of the cam to rotate to a vertically upward position. At this time, the first lifting plate can move upward and reset under the action of the first spring, simultaneously driving multiple moving rods to move downward. Then, when the pneumatic suction head comes into contact with the top of the TV frame, it can adsorb it. After adsorption is complete, the TV frame is lifted a little distance, and the motor is started again, causing the tip of the cam to come into contact with the top of the first lifting plate, thereby pushing the first lifting plate downward and driving the moving rods downward. When the ball comes into contact with the top of the TV frame, it can push the moving rods and the fixed column upward. At the same time, the second spring is compressed, and... The stop block drives the second lifting plate upward. The proximity switch detects the sensing block. If the pneumatic suction head becomes loose during adsorption, the moving rod pushes the TV frame away from the pneumatic suction head. The moving rod then moves downward to reset under the action of the second spring. At this point, under the action of gravity, the second lifting plate and the sensing block can move downward. If the proximity switch cannot detect the sensing block, an alarm is triggered. Since the TV frame is raised to a low height, it will not be damaged. This allows for automatic detection of the reliability of the adsorption after the pneumatic suction head has adsorbed the TV frame, preventing it from falling off during transfer and ensuring the quality of the stamping process.

[0039] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0040] The automatic stamping equipment for TV frames is a highly efficient and precise automated device used for the production and processing of TV frames. This equipment typically consists of a frame, molds, a punch press, a feeding conveyor, an unloading conveyor, as well as auxiliary robotic arms and a material transfer module. The material transfer module is used to transfer the TV frame to achieve multiple stamping operations. The material transfer module is equipped with multiple vacuum suction cups for adsorbing the TV frame.

[0041] After conducting in-depth investigation and research on the automatic stamping process of TV bezels, the inventors discovered that in existing automatic TV bezel stamping equipment, the material of the TV bezel undergoes plastic deformation under external force during the stamping process. This deformation may lead to stress concentration and uneven distribution. Specifically, bending and stretching processes during stamping can generate internal stress in the material, thus affecting the stamping quality. At the same time, burrs and folds in the punched holes after stamping also affect the stamping quality. Furthermore, during transfer, the vacuum suction cup may not adhere tightly, causing the bezel to fall off during transfer, which also affects the stamping quality. To address these issues, the inventors proposed an automatic TV bezel stamping device.

[0042] The present invention provides the following preferred embodiments.

[0043] like Figures 1-8As shown, an automatic stamping device for television bezels includes multiple stamping modules 101 and material transfer modules 102. Each material transfer module 102 includes a moving plate 103. Two symmetrically arranged mounting plates 104 are fixedly connected to the side wall of the moving plate 103, and multiple pneumatic suction heads 105 are fixedly connected to the bottom of the mounting plate 104. The bottom of each mounting plate 104 is connected to a first lifting plate 11 through a first reset mechanism. The top of the first lifting plate 11 has multiple arrayed through holes 16. The movement of the first lifting plate 11 is driven by a pushing mechanism. The pneumatic suction heads 105 are inserted into the through holes 16. The top of the first lifting plate 11 has multiple arrayed moving rods 12 inserted into it. The moving rods 12 are connected to the first lifting plate through a second reset mechanism. The top of the moving rod 11 is connected, and the bottom of the moving rod 12 is provided with a ball bearing 13. The rotation of the moving rod 12 is driven by a drive mechanism. The side wall of the moving rod 12 is provided with multiple mounting slots 14. Each mounting slot 14 is connected to a grinding block 15 through a telescopic mechanism. The grinding block 15 includes an inclined surface 1501. A detection mechanism for detecting the movement of the moving rod 12 is provided above the first lifting plate 11. It can reciprocate to tap and vibrate the stamped TV frame. At the same time, it can automatically grind the inner wall of the punched hole, making it more convenient and faster to use. In addition, it can automatically detect the reliability of the adsorption after the pneumatic suction head 105 adsorbs the TV frame, so as to avoid the TV frame falling off during the transfer process, thereby ensuring the quality of stamping.

[0044] In this embodiment, as Figure 5 As shown, the first reset mechanism includes two symmetrically arranged first sleeves 601 fixedly connected to the top of the first lifting plate 11, and a first sleeve rod 602 is inserted into each first sleeve 601. The upper end of the first sleeve rod 602 is fixed to the bottom of the mounting plate 104, and a first spring 603 is sleeved on the side wall of each first sleeve 601, which plays a guiding and reset role for the movement of the first lifting plate 11.

[0045] In this embodiment, as Figure 5 As shown, the pushing mechanism includes an L-shaped plate 701 fixedly connected to the side wall of the mounting plate 104, and a motor 702 fixedly connected to the side wall of the L-shaped plate 701. A cam 703 is fixedly connected to the output end of the motor 702, and the cam 703 slides on the top of the first lifting plate 11. When the motor 702 is started, the rotation of the motor 702 drives the rotation of the cam 703. When the tip of the cam 703 abuts against the top of the first lifting plate 11, it can push the first lifting plate 11 to move downward.

[0046] In this embodiment, as Figure 6 and Figure 7As shown, the second reset mechanism includes a fixed column 201 fixedly connected to the upper end of the moving rod 12, and a second spring 202 is sleeved on the side wall of the moving rod 12. A rotating ring 203 is fixedly connected to the lower end of the second spring 202, and the rotating ring 203 is rotatably connected to the top of the first lifting plate 11. The upper end of the second spring 202 is fixed to the bottom of the fixed column 201, which plays a guiding and reset role in the movement of the moving rod 12.

[0047] In this embodiment, as Figure 6 and Figure 7 As shown, the driving mechanism includes a spiral groove 301 formed on the side wall of the fixed column 201, and the bottom of the mounting plate 104 is connected to a plurality of arrayed push pins 302 through the mounting mechanism. The push pins 302 are inserted into the spiral groove 301. When the first lifting plate 11 moves downward, the push pins 302 can slide in the spiral groove 301, thereby pushing the fixed column 201 to rotate, which in turn drives the moving rod 12 and the grinding block 15 to rotate.

[0048] In this embodiment, as Figure 5 and Figure 7 As shown, the installation mechanism includes multiple arrayed fixing plates 401 fixedly connected to the bottom of the mounting plate 104. Multiple arrayed mounting blocks 402 are fixedly connected to the bottom of each fixing plate 401, and the push pin 302 is fixed to the side wall of the mounting block 402 to achieve the installation and fixation of the push pin 302.

[0049] In this embodiment, as Figure 8 As shown, the telescopic mechanism includes two symmetrically arranged second sleeves 501 fixedly connected to the side walls of each grinding block 15, and a second sleeve rod 502 is inserted into each second sleeve 501. The other end of the second sleeve rod 502 is fixed to the side wall of the mounting groove 14, and a third spring 503 is sleeved on the side wall of each second sleeve 501. When the inclined surface 1501 abuts against the top of the punch hole, it can push the grinding block 15 to slide into the mounting groove 14. At the same time, the third spring 503 is compressed, so that the grinding block 15 can move into the punch hole and abut against the hole wall.

[0050] In this embodiment, as Figure 7As shown, the detection mechanism includes a second lifting plate 802, which is connected to the side wall of the fixed plate 401 via a guide mechanism. Multiple arrayed blocks 801 are fixedly connected to the side wall of the second lifting plate 802, with the blocks 801 abutting against the top of the fixed column 201. The movement of the second lifting plate 802 is detected by a detection component. After vibration is complete, the motor 702 is started, causing the tip of the cam 703 to rotate to a vertically upward position. At this time, the first lifting plate 11 can move upward and reset under the action of the first spring 603, simultaneously driving multiple moving rods 12 to move downward. Then, when the pneumatic suction head 105 abuts against the top of the TV frame, it can adsorb the airflow. After adsorption is complete, the TV frame is lifted a short distance, and the motor 702 is started again. The mechanism 702 causes the tip of the cam 703 to abut against the top of the first lifting plate 11, thereby pushing the first lifting plate 11 downward and driving the moving rod 12 downward. When the ball 13 abuts against the top of the TV frame, it can push the moving rod 12 and the fixed column 201 upward. At the same time, the second spring 202 is compressed, and the second lifting plate 802 is driven upward by the stop block 801. If the pneumatic suction head 105 is loose during suction, the TV frame can be pushed away from the pneumatic suction head 105 by the pushing action of the moving rod 12. At this time, the moving rod 12 can move downward and reset under the action of the second spring 202. At this time, the second lifting plate 802 can move downward under the action of gravity and be detected by the detection component.

[0051] In this embodiment, as Figure 7 As shown, the guiding mechanism includes two symmetrically arranged T-shaped guide rods 902 fixedly connected to the top of the second lifting plate 802. The side wall of the T-shaped guide rod 902 is fitted with a connecting plate 901, and the connecting plate 901 is fixed to the side wall of the fixing plate 401, which plays a guiding and limiting role in the movement of the second lifting plate 802.

[0052] In this embodiment, as Figure 7 As shown, the detection component includes a sensing block 1001 fixedly connected to the top of the second lifting plate 802, and a proximity switch 1002 fixedly connected to the bottom of the connecting plate 901. The proximity switch 1002 is electrically connected to an external alarm. When the moving rod 12 and the fixed column 201 move upward, the second lifting plate 802 moves upward through the stop block 801. The proximity switch 1002 detects the sensing block 1001. If the pneumatic suction head 105 becomes loose during adsorption, the second lifting plate 802 and the sensing block 1001 can move downward. When the proximity switch 1002 cannot detect the sensing block 1001, an alarm operation is triggered.

[0053] The specific steps for using this invention are as follows:

[0054] In use, firstly, after each stamping is completed, the material transfer module 102 moves the moving plate 103 and the mounting plate 104, moving the first lifting plate 11 to the top of the TV frame. Then, the motor 702 is started, and its rotation drives the cam 703 to rotate. When the tip of the cam 703 abuts against the top of the first lifting plate 11, it pushes the first lifting plate 11 downwards. Simultaneously, the first spring 603 is compressed. When the tip of the cam 703 passes the top of the first lifting plate 11, the first lifting plate 11 is able to move downwards along the spring 603. Under the action of 3, the first lifting plate 11 moves downward to reset. This process is repeated to allow the first lifting plate 11 to move up and down. When the first lifting plate 11 moves downward, it can drive multiple moving rods 12 to move downward through the second reset mechanism. When the ball bearing 13 abuts against the top of the TV frame, the second spring 202 can be stretched. When the first lifting plate 11 moves upward, it can drive multiple moving rods 12 to move upward to reset through the second reset mechanism. This process is repeated to allow the ball bearing 13 to repeatedly strike and vibrate the stamped TV frame, which helps to remove internal stress and ensures the quality of stamping.

[0055] When the first lifting plate 11 moves downward, the second reset mechanism drives multiple moving rods 12 to move downward. When the moving rods 12 are aligned with the punch hole, they can be inserted into the punch hole. When the inclined surface 1501 abuts against the top of the punch hole, it can push the grinding block 15 to slide into the mounting groove 14. At the same time, the third spring 503 is compressed, so that the grinding block 15 can move into the punch hole and abut against the hole wall. Meanwhile, when the first lifting plate 11 moves downward, the push pin 302 can slide in the spiral groove 301, thereby pushing the fixed column 201 to rotate, which in turn drives the moving rods 12 and the grinding block 15 to rotate. This allows for automatic grinding of the inner wall of the punch hole, making it more convenient and faster to use, and ensuring the quality of stamping.

[0056] After vibration is complete, start motor 702, so that the tip of cam 703 rotates to a vertically upward position. At this time, the first lifting plate 11 can move upward and reset under the action of the first spring 603. At the same time, it drives multiple moving rods 12 to move downward. Then, when the pneumatic suction head 105 comes into contact with the top of the TV frame, it can adsorb it. After adsorption is completed, lift the TV frame a little distance, start motor 702 again, so that the tip of cam 703 comes into contact with the top of the first lifting plate 11, thereby pushing the first lifting plate 11 to move downward and driving the moving rods 12 to move downward. When the ball 13 comes into contact with the top of the TV frame, it can push the moving rods 12 and the fixed column 201 to move upward. At the same time, the second spring 202 is compressed, and the second lifting plate 802 is driven to move upward through the stop block 801. The proximity switch 1002 detects the sensing block 1001.

[0057] If the pneumatic suction head 105 becomes loose during adsorption, the moving rod 12 can push the TV frame away from the pneumatic suction head 105. At this time, the moving rod 12 can move downward to reset under the action of the second spring 202. At this time, under the action of gravity, the second lifting plate 802 and the sensing block 1001 can move downward. When the proximity switch 1002 cannot detect the sensing block 1001, an alarm operation is performed. At this time, since the TV frame is raised to a low height, it will not cause damage to the TV frame. Thus, the reliability of the adsorption of the pneumatic suction head 105 can be automatically detected after adsorption, avoiding the TV frame from falling off during the transfer process, thereby ensuring the quality of stamping.

[0058] In summary, the beneficial effects of this invention are specifically reflected in its ability to repeatedly tap and vibrate the stamped TV frame, while simultaneously performing automatic polishing of the inner wall of the punched holes, making it more convenient and faster to use. Furthermore, it can automatically detect the reliability of the adsorption after the pneumatic suction head 105 adsorbs the TV frame, preventing the TV frame from falling off during the transfer process, thereby ensuring the quality of stamping.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
