Description

Technical Field

[0001] The present invention relates to the field of cutting equipment, and more specifically, to a cutting equipment for producing the metal backplane of a television set. Background Art

[0002] After the metal backplane of a television set is stamped and formed, the excess edge material of the backplane needs to be cut off. A cutting equipment is required during cutting. For example, a Chinese patent document with publication number CN107962612A and title "A Cutting Device for the Edge Material of a Television Backplane" discloses a cutting device dedicated to the television backplane. This device uses four first servo motors to drive four lead screws respectively, thereby driving four second servo motors to move back and forth respectively, so that the cutting knives thereon cut the edge materials on the four sides of the television backplane respectively. However, in this structure, four first servo motors are required to drive four lead screws respectively, with many power components, a relatively complex structure, and a high cost. In addition, during processing, the television backplane is placed on a placement plate, and there is no pressing mechanism provided. It can only rely on the side surfaces of the boxes around the placement plate for positioning. In this way, it is difficult to fix the television backplane well, and it is easy to shift during cutting, resulting in uneven cutting. At the same time, it can only process television backplanes of the same specification, with poor adaptability. Summary of the Invention

[0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a cutting equipment with fewer power components, applicable to different specifications of television backplanes, and capable of fixing the television backplane well during processing.

The pushing assembly acts on one side of the lever member close to the hinge. The first positioning plate and the second positioning plate are respectively disposed on the top ends of the first telescopic member and the second telescopic member.

[0009] Further, the pushing assembly includes an upper cross bar, a lower cross bar, two connecting columns, and a plurality of top columns. The two connecting columns are respectively located on both sides of the workbench and are vertically movably disposed on the workbench. The two ends of the upper cross bar are respectively fixedly connected to the upper ends of the two connecting columns. The two ends of the lower cross bar are respectively fixedly connected to the lower ends of the two connecting columns. The middle part of the lower cross bar acts on the lever member. A plurality of top columns are disposed on the upper cross bar, and when the upper cross bar is in the highest position, the top ends of the top columns exceed the operation board.

[0010] Further, a gantry-type bracket is provided on the workbench. The operation table is disposed in the middle of the top surface of the bracket.

[0026] Refer to Figures 1 to 4A cutting device for producing the metal backplane of a TV set, comprising an operating board 10 for placing the metal backplane and four cutting machines 20, further comprising:

[0027] A positioning mechanism, which is telescopically movable near the operating board 10 and is used to adjust the positioning position to position metal backplanes of different specifications, so that the metal backplane is placed on the operating board 10 in a correct posture;

[0028] A pressing mechanism, which is used to press the top surface of the metal backplane placed on the operating board 10, and when pressing, it pushes the positioning mechanism to retract away from the operating board 10 so that it does not affect the cutting operation;

[0029] A first driving mechanism, which is used to fixedly connect two of the cutting machines 20 and can drive the two cutting machines 20 to reciprocate simultaneously to cut two opposite sides of the metal backplane;

[0030] A second driving mechanism, which is used to fixedly connect the other two cutting machines 20 and can drive the two cutting machines 20 to reciprocate simultaneously to cut the other two opposite sides of the metal backplane.

[0031] In an embodiment, as Figures 1 to 3 , the cutting device further comprises a workbench 1, as a loading platform, and the operating board 10, the positioning mechanism, the pressing mechanism, the first driving mechanism and the second driving mechanism are all arranged on the workbench 1.

[0032] In an embodiment, as Figures 1 to 4 , a gantry-type support 11 is arranged on the workbench 1, the operating table is arranged in the middle of the top surface of the support 11, and gantry-type top frames 12 striding across the first driving mechanism are arranged on both sides of the workbench 1.

[0033] In an embodiment, as Figure 1 and Figure 4, the first driving mechanism includes two first guide rails 21, a first slide plate 22, a first screw 23 and a first motor 24. The two first guide rails 21 are arranged in parallel on the workbench 1 and are respectively located on both sides of the bracket 11. The first slide plate 22 is located below the bracket 11 and its two ends are respectively slidably connected to the two first guide rails 21. The first screw 23 is arranged in parallel with the first guide rail 21 and is threadedly connected to the first slide plate 22. The first motor 24 is arranged on one side of the workbench 1 and its output end is fixedly connected to the first screw 23. The two cutting machines 20 can respectively move towards the bracket 11 and are lockably arranged at both ends of the first slide plate 22. T-shaped grooves and T-shaped blocks are provided at both ends of the first slide plate 22. At the same time, screws are used to pass through the mounting plate of the first motor 24 and are threadedly connected to the T-shaped blocks in the T-shaped grooves. When loosened, the cutting machine 20 can move along the T-shaped groove, and after tightening the screws, the cutting machine 20 can be fixed. Since the position of the first screw 23 is low and it is easily soiled by the hardware powder cut off, an existing corrugated expansion pipe (not shown in the figure) can be sleeved on the first screw 23 to better isolate the hardware powder.

[0034] In one embodiment, as Figure 1 and Figure 4 , the second driving mechanism includes two second guide rails 31, a second slide plate 32, a second screw 33 and a second motor 34. The two second guide rails 31 are arranged in parallel on the top frame 12 and are perpendicular to the first guide rail 21. The two ends of the second slide plate 32 are respectively slidably connected to the two second guide rails 31. The second screw 33 is arranged in parallel with the second guide rail 31 and is threadedly connected to the second slide plate 32. The second motor 34 is arranged on the workbench 1 and its output end is fixedly connected to the second screw 33. The other two cutting machines 20 can respectively move towards being parallel to the bracket 11 and are lockably arranged at both ends of the second slide plate 32. Preferably, the second driving mechanism further includes two hanging brackets 35. The two hanging brackets 35 can respectively move towards being parallel to the bracket 11 and are lockably arranged at both ends of the second slide plate 32. The other two cutting machines 20 are respectively fixedly connected to the two hanging brackets 35, which is convenient for the other two cutting machines 20 to be at the same height as the two cutting machines 20 on the first slide plate 22.

[0035] In the above embodiments, the second screw rod 33 is located between two second guide rails 31 and close to one of the second guide rails 31. Such a setting can create space in the middle, facilitating the picking and placing of the hardware backplane. Since the second screw rod 33 is arranged close to one of the second guide rails 31, the force when driving the second slide plate 32 to move is relatively unbalanced. Therefore, an adjusting member 36 is provided to increase the friction between the second slide plate 32 and the second guide rail 31 on the side of the second screw rod 33. Specifically, the adjusting member 36 is threadedly connected to one end of the second slide plate 32 close to the second screw rod 33, and the end of the adjusting member 36 passes through the second slide plate 32 and abuts against the second guide rail 31. When the adjusting member 36 is tightened, the friction increases, and when it is loosened, the friction decreases, which is set according to actual needs.

[0036] In one embodiment, as Figure 1 and Figure 4 , the pressing mechanism includes a pressing rod 41, a pressing plate 42 and a driving member 43. The pressing rod 41 is hinged to the workbench 1, and the driving member 43 is fixedly connected to the bottom surface of the workbench 1 and is used to push one end of the pressing rod 41 to rotate up and down. The pressing plate 42 is universally connected to the other end of the pressing rod 41 and can rotate downward with this end to fit onto the working plate 10. When the driving member 43 pushes one end of the pressing rod 41 to rotate upward, the other end drives the pressing plate 42 to rotate downward until the TV hardware backplane is pressed tightly. At this time, it will push the positioning mechanism to retract away from the working plate 10. The driving member 43 preferably adopts a cylinder. The output end of the cylinder is fixedly connected with a concave plate 44. The concave plate 44 is provided with a strip-shaped groove, and one end of the pressing rod 41 is connected with the strip-shaped groove through a pin shaft. The universal connection between the pressing plate 42 and the other end of the pressing rod 41 can adapt to hardware backplanes of different thicknesses and can automatically adjust the pressing of the hardware backplane.

[0037] In one embodiment, referring to Figures 1 to 4 , the positioning mechanism includes a first positioning plate 51, a second positioning plate 52, a telescopic assembly, a pushing assembly and a lever member 55. The telescopic assembly is movably inserted through the workbench 1 up and down. The first positioning plate 51 and the second positioning plate 52 are both arranged at the top of the telescopic assembly and can respectively adjust their positions relative to the workbench 1 for respectively abutting against two adjacent edges of the hardware backplane. The pushing assembly is movably inserted through the workbench 1 up and down, and when it moves to the highest position, its top end exceeds the working plate 10. The lever member 55 is arranged below the workbench 1 and is driven by the pushing assembly to drive the telescopic assembly to move by a greater amplitude than the pushing assembly. Through the amplification effect of the lever member 55, when the pushing assembly moves downward by a small amplitude, it can push the telescopic assembly to move downward by a large amplitude, so that the telescopic assembly and the first positioning plate 51 and the second positioning plate 52 thereon move away from the working plate 10, that is, below the first slide plate 22 and will not hinder the back-and-forth movement of the first slide plate 22.

[0038] In one embodiment, referring to Figures 1 to 4, the telescopic assembly includes a first telescopic member 531, a second telescopic member 532, a connecting plate 533, a guide post 534 and an elastic member 535. The first telescopic member 531 and the second telescopic member 532 are respectively arranged on the workbench 1 in a vertically movable manner. The guide post 534 is vertically and fixedly connected to the bottom surface of the workbench 1. The connecting plate 533 is movably connected to the guide post 534 in a vertically movable manner. The two ends of the connecting plate 533 are respectively fixedly connected to the bottom ends of the first telescopic member 531 and the second telescopic member 532. The elastic member 535 abuts against the bottom surface of the connecting plate 533. One end of the lever member 55 is hinged to the bottom surface of the workbench 1 and the other end abuts against the top surface of the connecting plate 533. The pushing assembly acts on one side of the lever member 55 close to the hinge. The first positioning plate 51 and the second positioning plate 52 are respectively arranged at the top ends of the first telescopic member 531 and the second telescopic member 532.

[0039] In one embodiment, referring to Figures 1 to 4 , the pushing assembly includes an upper cross bar 541, a lower cross bar 542, two connecting columns 543 and a plurality of ejector pins 544. The two connecting columns 543 are respectively located on both sides of the workbench 1 and are arranged on the workbench 1 in a vertically movable manner. The two ends of the upper cross bar 541 are respectively fixedly connected to the upper ends of the two connecting columns 543. The two ends of the lower cross bar 542 are respectively fixedly connected to the lower ends of the two connecting columns 543. The middle part of the lower cross bar 542 acts on the lever member 55. A plurality of ejector pins 544 are arranged on the upper cross bar 541. When the upper cross bar 541 is in the highest position, the top ends of the ejector pins 544 exceed the working plate 10. The number of ejector pins 544 is not less than three. Preferably, four are adopted as shown in the drawings. And two upper cross bars 541 are adopted and are respectively arranged on both sides of the bracket 11. Two ejector pins 544 are arranged on each upper cross bar 541. The top ends of the ejector pins 544 can pass through and exceed the working plate 10. A metal back plate is placed on the workbench 1 and is supported by the top ends of the ejector pins 544 and does not contact the working plate 10 temporarily. Under the pressing of the pressing plate 42 of the pressing mechanism, it will push the ejector pins 544 to move downward and retract until the metal back plate fits with the working plate 10.

[0040] The above-mentioned hanging bracket 35 and the second sliding plate 32, the first positioning plate 51 and the first telescopic member 531, the second positioning plate 52 and the second telescopic member 532 are all connected by T-shaped grooves, T-shaped blocks and screws, just like the connection method between the cutting machine 20 and the first sliding plate 22.

[0041] The above embodiments are only explanations of the present invention, and they are not limitations of the present invention. Those skilled in the art can make modifications to the present embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
