[0001] The invention relates to the technical field of television frame production, in particular to an automatic punching device for a television frame. Background Art

[0002] The automatic punching equipment for TV frames is an efficient and precise automated equipment used for the production and processing of TV frames. The equipment is usually composed of a frame, a mold, a punching machine, a loading conveyor, a unloading conveyor, an auxiliary manipulator 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] Publication No. CN116551406B discloses a photovoltaic frame processing equipment. However, when the existing automatic TV frame stamping equipment is in use, during the stamping process, the material of the TV frame will be affected by external force and undergo plastic deformation. This deformation may lead to stress concentration and uneven distribution. Specifically, bending, stretching and other processes in the stamping process will cause stress inside the material, thereby affecting the quality of stamping. At the same time, the punching holes after stamping have burrs and flanging, which will also affect the quality of stamping. In addition, during the transfer, the vacuum suction cup may not be tightly adsorbed, causing it to fall off during the transfer process, which will also affect the quality of stamping. Summary of the invention

[0004] The present invention aims at the technical problems existing in the prior art and provides an automatic punching device for a television frame to solve the problem that when the existing automatic punching device for a television frame is in use, during the punching process, the material of the television frame will be subjected to the action of external force and undergo plastic deformation, and this deformation may lead to stress concentration and uneven distribution. Specifically, bending, stretching and other processes in the stamping process will cause stress to be generated inside the material, thereby affecting the quality of the stamping. At the same time, the punched holes after stamping have burrs and flanging, which will also affect the quality of the stamping. In addition, during the transfer, the vacuum suction cup may not be adsorbed tightly during adsorption, causing it to fall off during the transfer process, which will also affect the quality of the stamping.

[0006] Based on the above technical solution, the present invention can also be 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 each first sleeve has a first rod inserted therein, the upper end of the first rod is fixed to the bottom of the mounting plate, and the side wall of each first sleeve is sleeved with a first spring.

[0008] The beneficial effect of adopting the above further solution is that it plays a guiding and resetting role in the movement of the first lifting plate.

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

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

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

[0012] The beneficial effect of adopting the above further solution is that it plays a guiding and resetting role in the movement of the moving rod.

[0013] Furthermore, the driving mechanism includes a spiral groove opened on the side wall of the fixing column, and the bottom of the mounting plate is connected to a plurality of push pins arranged in an array through the mounting mechanism, and the push pins are inserted in the spiral groove.

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

[0015] Furthermore, the mounting mechanism includes a plurality of array-arranged fixing plates fixedly connected to the bottom of the mounting plate, a plurality of array-arranged mounting blocks are fixedly connected to the bottom of each fixing plate, and a push pin is fixed to a side wall of the mounting block.

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

[0019] Furthermore, the detection mechanism includes a second lifting plate, and the second lifting plate is connected to the side wall of the fixed plate through a guide mechanism, the side wall of the second lifting plate is fixedly connected with a plurality of array-arranged blocks, the blocks are abutted against the top of the fixed column, and the movement of the second lifting plate is detected by the detection component.

[0020] The beneficial effect of adopting the above further scheme 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, and at the same time, drive multiple moving rods to move downward. Then, when the pneumatic suction head is against the top of the TV frame, it can be adsorbed. After the adsorption is completed, the TV frame is lifted a little distance, and the motor is started again so that the tip of the cam is against the top of the first lifting plate, thereby pushing the first lifting plate to move downward and driving the moving rod to move downward. When the ball is against the top of the TV frame, the moving rod and the fixed column can be pushed upward. At the same time, the second spring is compressed, and the second lifting plate is driven to move upward through the block. If the pneumatic suction head is loose during adsorption, at this time, under the pushing action of the moving rod, the TV frame can be pushed to separate from the pneumatic suction head. 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 guide 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 sleeved 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 further solution is that it plays a guiding and limiting role in the movement of the second lifting plate.

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

[0024] The beneficial effect of adopting the above further scheme is that when the movable rod and the fixed column move upward, the second lifting plate is driven to move upward through the block, and the sensing block is detected by the proximity switch. If the pneumatic suction head becomes 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 the present invention are:

[0026] 1) By setting a first reset mechanism and a first pushing mechanism, after each stamping is completed, the moving plate and the mounting plate are driven to move through the material shifting module, and the first lifting plate is moved 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, the first lifting plate can be pushed to move downward. At the same time, the first spring is compressed. When the tip of the cam passes over the top of the first lifting plate, the first lifting plate can move downward and reset under the action of the first spring. This reciprocating process can make the first lifting plate reciprocate and lift. When the first lifting plate moves downward, the second reset mechanism can be used to drive multiple moving rods to move downward. When the ball is against the top of the TV frame, the second spring can be stretched. When the first lifting plate moves upward, the second reset mechanism drives multiple moving rods to move upward and reset. This reciprocating process can make the ball reciprocate and knock and vibrate the TV frame after stamping, which is convenient for removing internal stress and ensuring the quality of stamping.

[0027] 2) By setting a driving mechanism, when the first lifting plate moves downward, the multiple moving rods are driven to move downward through the second reset mechanism. When the moving rod is aligned with the punching hole, it can be inserted into the punching hole. When the inclined surface abuts against the top of the punching hole, the grinding block can be pushed to slide into the installation groove. At the same time, the third spring is compressed, so that the grinding block can move into the punching hole and abut against the hole wall. At the same time, when the first lifting plate moves downward, the pushing pin can slide in the spiral groove, thereby pushing the fixed column to rotate, and then driving the moving rod and the grinding block to rotate, so that the inner wall of the punching hole can be automatically polished, which is more convenient and quick to use and ensures the quality of stamping.

[0028] 3) By setting up a detection mechanism, after the vibration is completed, the motor is started to make the tip of the cam rotate to a vertically upward state. At this time, the first lifting plate can move upward and reset under the action of the first spring, and at the same time, drive multiple moving rods to move downward. Then, when the pneumatic suction head is against the top of the TV frame, it can be adsorbed. After the adsorption is completed, the TV frame is lifted a little distance, and the motor is started again to make the tip of the cam against the top of the first lifting plate, thereby pushing the first lifting plate to move downward and driving the moving rod to move downward. When the ball is against the top of the TV frame, it can push the moving rod and the fixed column to move upward. At the same time, the second spring is compressed, and The second lifting plate is driven upward by the block, and the sensing block is detected by the proximity switch. If the pneumatic suction head is loose during adsorption, the TV frame can be pushed out of 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 and the sensing block can move downward. When the proximity switch cannot detect the sensing block, an alarm operation is performed. At this time, since the height of the TV frame is lifted is relatively low, the TV frame will not be damaged. Therefore, after the pneumatic suction head is adsorbed, the reliability of its adsorption can be automatically detected to avoid the TV frame falling off during the transfer process, thereby ensuring the quality of stamping.

DETAILED DESCRIPTION

[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] The automatic punching equipment for TV frames is an efficient and precise automated equipment used for the production and processing of TV frames. The equipment is usually composed of a frame, a mold, a punching machine, a loading conveyor, a unloading conveyor, an auxiliary manipulator 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 in-depth investigation and research on the automatic stamping process of TV frames, the inventor found that when the existing automatic stamping equipment for TV frames is in use, during the stamping process, the material of the TV frame will be affected by external force and undergo plastic deformation. This deformation may lead to stress concentration and uneven distribution. Specifically, bending, stretching and other processes in the stamping process will cause stress inside the material, thereby affecting the quality of stamping. At the same time, the punching holes after stamping have burrs and flanging, which will also affect the quality of stamping. Moreover, during the transfer, the vacuum suction cup may not be tightly adsorbed, causing it to fall off during the transfer process, which will also affect the quality of stamping. In response to this, the inventor proposed an automatic stamping equipment for TV frames to solve the above problems.

The top of the moving rod 11 is connected, and a ball 13 is arranged at the bottom of the moving rod 12. The rotation of the moving rod 12 is driven by a driving mechanism, and a plurality of mounting grooves 14 are opened on the side wall of the moving rod 12. A grinding block 15 is connected to each mounting groove 14 through a telescopic mechanism, and the grinding block 15 includes an inclined surface 1501. A detection mechanism for detecting the movement of the moving rod 12 is arranged above the first lifting plate 11, which can reciprocately knock and vibrate the punched TV frame, and at the same time, can automatically grind the inner wall of the punched hole, which is more convenient and quick to use. Moreover, after the pneumatic suction head 105 is adsorbed, the reliability of its adsorption can be automatically detected to avoid the TV frame falling off during the transfer process, thereby ensuring the quality of stamping.

[0046] In this embodiment, 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 the side wall of the moving rod 12 is sleeved with a second spring 202, the lower end of the second spring 202 is fixedly connected with a rotating ring 203, and the rotating ring 203 is rotatably connected to the top of the first lifting plate 11, and the upper end of the second spring 202 is fixed to the bottom of the fixed column 201, which guides and resets the movement of the moving rod 12.

[0047] In this embodiment, Figure 6 and Figure 7 As shown, the driving mechanism includes a spiral groove 301 opened on the side wall of the fixed column 201, and the bottom of the mounting plate 104 is connected to a plurality of push pins 302 arranged in an array through the mounting mechanism. The push pins 302 are inserted in 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, and then driving the moving rod 12 and the grinding block 15 to rotate.

[0048] In this embodiment, Figure 5 and Figure 7 As shown, the mounting mechanism includes a plurality of array-arranged fixing plates 401 fixedly connected to the bottom of the mounting plate 104, a plurality of array-arranged 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 installation and fixation of the push pin 302.

[0049] In this embodiment, 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 in 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 the side wall of each second sleeve 501 is sleeved with a third spring 503. When the inclined surface 1501 abuts against the top of the punching hole, the grinding block 15 can be pushed 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 punching hole and make the grinding block 15 abut against the hole wall.

[0050] In this embodiment, Figure 7As shown, the detection mechanism includes a second lifting plate 802, and the second lifting plate 802 is connected to the side wall of the fixed plate 401 through a guiding mechanism, and the side wall of the second lifting plate 802 is fixedly connected with a plurality of block blocks 801 arranged in an array, and the block blocks 801 are against the top of the fixed column 201, and the movement of the second lifting plate 802 is detected by the detection component. After the vibration is completed, the motor 702 is started to rotate the tip of the cam 703 to a vertically upward state. At this time, the first lifting plate 11 can move upward and reset under the action of the first spring 603, and at the same time, drive the plurality of moving rods 12 to move downward, and then, when the pneumatic suction head 105 is against the top of the TV frame, it can be adsorbed. After the adsorption is completed, the TV frame is lifted a little distance, and the electric motor is started again. The machine 702 makes the tip of the cam 703 abut against the top of the first lifting plate 11, thereby pushing the first lifting plate 11 to move downward and driving the moving rod 12 to move downward. When the ball 13 abuts against the top of the TV frame, the moving rod 12 and the fixed column 201 can be pushed upward. At the same time, the second spring 202 is compressed and the second lifting plate 802 is driven to move upward through the stopper 801. If the pneumatic suction head 105 is loose during adsorption, at this time, under the pushing action of the moving rod 12, the TV frame can be pushed to separate from the pneumatic suction head 105. At this time, the moving rod 12 can move downward and reset under the action of the second spring 202. At this time, under the action of gravity, the second lifting plate 802 can move downward and be detected by the detection component.

[0051] In this embodiment, Figure 7 As shown, the guide mechanism includes two symmetrically arranged T-shaped guide rods 902 fixedly connected to the top of the second lifting plate 802, and the side walls of the T-shaped guide rods 902 are sleeved with connecting plates 901, and the connecting plates 901 are fixed to the side walls of the fixed plate 401, which guide and limit the movement of the second lifting plate 802.

[0052] In this embodiment, 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 is fixedly connected to the bottom of the connecting plate 901. The proximity switch 1002 is electrically connected to the external alarm. When the moving rod 12 and the fixed column 201 move upward, the second lifting plate 802 is driven to move upward through the block 801, and the sensing block 1001 is detected by the proximity switch 1002. If the pneumatic suction head 105 is 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 performed.

[0053] The specific method of use of the present invention is as follows:

[0054] When in use, first, after each stamping is completed, the material moving module 102 drives the moving plate 103 and the mounting plate 104 to move, and moves the first lifting plate 11 to the top of the TV frame, then starts the motor 702, and 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, the first lifting plate 11 can be pushed to move downward. At the same time, the first spring 603 is compressed. When the tip of the cam 703 passes over the top of the first lifting plate 11, the first lifting plate 11 can be 3, and the first lifting plate 11 can be lifted and lowered reciprocatingly. When the first lifting plate 11 moves downward, the plurality of moving rods 12 can be driven downward by the second resetting mechanism. When the ball 13 abuts against the top of the TV frame, the second spring 202 can be stretched. When the first lifting plate 11 moves upward, the plurality of moving rods 12 can be driven upward by the second resetting mechanism to be reset. In this way, the ball 13 can reciprocately knock and vibrate the punched TV frame, so as to remove the internal stress and ensure the quality of the punching.

[0055] When the first lifting plate 11 moves downward, the plurality of moving rods 12 are driven to move downward by the second reset mechanism. When the moving rod 12 is aligned with the punching hole, it can be inserted into the punching hole. When the inclined surface 1501 abuts against the top of the punching hole, the grinding block 15 can be pushed 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 punching hole and abut against the hole wall. At the same time, when the first lifting plate 11 moves downward, the pushing pin 302 can slide in the spiral groove 301, thereby pushing the fixed column 201 to rotate, thereby driving the moving rod 12 and the grinding block 15 to rotate, and the inner wall of the punching hole can be automatically polished, which is more convenient and quick to use and ensures the quality of stamping.

[0056] After the vibration is completed, the motor 702 is started, so that the tip of the cam 703 rotates to a vertically upward state. At this time, the first lifting plate 11 can move upward and reset under the action of the first spring 603, and at the same time, drive the multiple moving rods 12 to move downward. Then, when the pneumatic suction head 105 is against the top of the TV frame, it can be adsorbed. After the adsorption is completed, the TV frame is lifted a little distance, and the motor 702 is started again, so that the tip of the cam 703 is against the top of the first lifting plate 11, so that the first lifting plate 11 can be pushed to move downward, and the moving rod 12 can be driven to move downward. When the ball 13 is against the top of the TV frame, the moving rod 12 and the fixed column 201 can be pushed 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 stopper 801, and the sensor block 1001 is detected by the proximity switch 1002;

[0057] If the pneumatic suction head 105 is loose during adsorption, at this time, under the pushing action of the moving rod 12, the TV frame can be pushed away from the pneumatic suction head 105. At this time, the moving rod 12 can move downward and 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 height of the TV frame is lifted is relatively low, the TV frame will not be damaged. Therefore, after the pneumatic suction head 105 is adsorbed, the reliability of its adsorption can be automatically detected to avoid the TV frame falling off during the transfer process, thereby ensuring the quality of stamping.

[0058] In summary: The beneficial effects of the present invention are specifically embodied in that the punched TV frame can be reciprocatedly knocked and vibrated, and at the same time, the inner wall of the punched hole can be automatically polished, which is more convenient and quick to use. Moreover, after the pneumatic suction head 105 is adsorbed, the reliability of its adsorption can be automatically detected to avoid the TV frame 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
