DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] This embodiment aims to address the problem that the LED display back panel stamping and forming equipment in the prior art cannot continuously and quickly feed materials during the stamping and forming operation, and the equipment needs to be repeatedly turned on and off to put in or take out the stamping raw materials, which greatly reduces the work efficiency and shortens the service life of the equipment.

[0033] like Figure 1-3As shown, a LED display back panel stamping forming device comprises a base 1, a feeding box 2 is fixed on one side of the upper surface of the base 1, a feeding port 22 and a discharging port 21 are respectively fixed on the upper and lower ends of the feeding box 2, and a rotating drum 25 is rotatably connected to the inside of the feeding box 2 at the center position, and a plurality of discharging cavities 24 are equidistantly opened on the outer side of the rotating drum 25, a grinding wheel 23 is rotatably connected to one side of the feeding box 2 at a position corresponding to the rotating drum 25, and the bottom of the stamping raw material is grinded by the grinding wheel 23 to keep it stable and horizontally placed later, thereby improving the yield rate of the subsequent stamping operation, and a feeding assembly 5 is installed between the feeding box 2 and the base 1;

[0034] The feeding assembly 5 includes a ratchet 56 rotatably connected to the front end of the feeding box 2, the rear end of the ratchet 56 penetrates and extends to the inside of the feeding box 2 and is fixed to the rotating drum 25, the front end of the feeding box 2 corresponds to a cam 54 rotatably connected to the position above the ratchet 56, one end of the cam 54 is fixed with a shifting block 57 adapted to the ratchet 56, and the front end of the cam 54 is fixed with a third sprocket 55, the rotation of the cam 54 drives the shifting block 57 to rotate, thereby intermittently shifting the ratchet 56 to rotate, and the ratchet 56 drives the rotating drum 25 to form intermittent motion, the front end of the grinding wheel 23 penetrates and extends to the outside of the feeding box 2, and the end of the grinding wheel 23 is fixedly installed with a fourth sprocket 59, the third sprocket 55 and the fourth sprocket 59 are meshed and driven by a third chain 58, and the front end of the fourth sprocket 59 is fixedly installed with a second motor 51, and the second motor 51 is installed on the outer layer of the feeding box 2;

[0035] The base 1 is internally rotatably connected to two rotating rollers 11, and the outer layers of the two rotating rollers 11 are rotatably connected to a conveying crawler 13. The outer layer of the conveying crawler 13 is equidistantly fixed with a number of limit plates 12. The limit plates 12 are used to maintain the stability of the stamping raw materials during transportation, and at the same time, a pushing effect is formed during the process of the stamping raw materials moving into the support frame 4, ensuring that the stamping raw materials enter the support frame 4 as a whole. The front end of the rotating roller 11 passes through and extends to the outside of the base 1, and a second sprocket 52 is fixedly installed at the front end of the rotating roller 11, and a second sprocket 52 is also fixedly installed at the front end of the ratchet 56, and two adjacent second sprockets 52 are connected by a second chain 53.

[0036] The raw materials for stamping parts are stacked inside the feed port 22, and then the second motor 51 is started to drive the fourth sprocket 59 to rotate. At this time, the fourth sprocket 59 cooperates with the third chain 58 and the third sprocket 55 to drive the cam 54 and the grinding wheel 23 to rotate. The rotation of the cam 54 drives the shift block 57 to rotate, thereby intermittently shifting the ratchet 56 to rotate, and the ratchet 56 drives the rotating drum 25 to form intermittent movement. With the continuous movement of the rotating drum 25, the discharge cavity 24 and the feed port 22 form a docking effect, and the raw materials for stamping parts enter the discharge cavity 24, and with the continuous movement of the rotating drum 25, finally fall to the upper surface of the conveyor crawler 13 through the discharge port 21. At the same time, during the rotation of the raw materials for stamping parts, when it rotates to the position of the grinding wheel 23, the bottom of the raw materials for stamping parts is polished by the grinding wheel 23 to ensure that the raw materials for stamping parts are in a horizontal state during the subsequent stamping process, thereby improving the overall stamping forming effect;

[0037] During the rotation of the ratchet 56, the second sprocket 52 and the second chain 53 drive the two rotating rollers 11 to rotate, and then drive the conveyor belt 13 to move. When the stamping part raw material falls onto the conveyor belt 13, the conveyor belt 13 slowly moves to the position of the support frame 4, and is completely moved into the support frame 4 with the push of the limit plate 12.

[0038] Embodiment 2:

[0039] This embodiment aims to address the problem that in the prior art LED display back panel stamping and forming equipment, it is difficult to form adaptive positioning for the stamped parts during the stamping and forming operation, and the stamped parts raw materials are easily damaged due to excessive clamping force.

[0040] like Figure 4-7 As shown, the embodiment is a stamping and forming device for a back panel of an LED display, and further includes a support frame 4 fixedly mounted on the other side of the upper surface of the base 1, a stamping assembly 3 is mounted inside the support frame 4, and the stamping assembly 3 includes two screw rods 36 symmetrically rotatably connected to the two sides of the inside of the support frame 4, a first sprocket 32 ​​is fixed to the top of the screw rod 36, a first chain 31 is rotatably connected between the two first sprockets 32, a first motor 33 is fixed to the top of one of the first sprockets 32 and extends to the outside of the support frame 4, and the first motor 33 is matched with a reducer to reduce the load pressure of the first motor 33 to meet the operation requirements;

[0041] The outer layers of the two screw rods 36 are commonly sleeved with a lifting plate 34, a punching block 35 is fixed to the bottom of the lifting plate 34, and two receiving grooves 310 are symmetrically opened on both sides of the lifting plate 34. Pressing blocks 37 are arranged at the positions of the receiving grooves 310 on both sides of the lifting plate 34, and the pressing blocks 37 can be completely moved into the receiving grooves 310, so as to match the limit state of the positioning assembly 8. The bottom of the pressing block 37 is equidistantly slidably sleeved with a plurality of first guide rods 39, and the first guide rods 39 can be completely accommodated in the pressing block 37. The outer layer of the first guide rod 39 is sleeved with a first spring 38 fixed in the receiving groove 310.

[0042] A stamping groove 6 is provided on the upper surface of the base 1 at a position corresponding to the support frame 4, and a positioning assembly 8 is installed between the stamping groove 6 and the base 1. The positioning assembly 8 includes four positioning columns 81 fixed to the upper surface of the base 1 at a position below the corresponding accommodating groove 310, and a second guide rod 83 is fixed inside the positioning column 81. A notch is provided on the inner side of the positioning column 81 at a position corresponding to the second guide rod 83. The outer layers of the two second guide rods 83 on the same side are slidably sleeved with a pressure rod 82, and the outer layer of the second guide rod 83 is sleeved with a second spring 84 fixed to the bottom of the pressure rod 82, and the elastic coefficient of the first spring 38 is much larger than the elastic coefficient of the second spring 84.

[0043] When the stamping material enters the support frame 4, the first motor 33 is started to cooperate with the first sprocket 32 ​​and the first chain 31 to drive the two screw rods 36 to rotate, and the rotation of the screw rods 36 drives the lifting plate 34 to descend, and the lowering of the lifting plate 34 drives the stamping block 35 to descend, thereby performing a stamping operation on the stamping material;

[0044] During the descent of the lifting plate 34, the pressure blocks 37 on both sides will first contact the pressure rod 82, and as the lifting plate 34 continues to press down, the pressure rod 82 is pressed down. As the pressure rod 82 descends until it contacts the stamping part raw material, the pressure block 37 is moved toward the inside of the accommodating groove 310 by the rebound force of the pressure rod 82. During the movement, the pressure block 37 is kept under pressure on the pressure rod 82 by the rebound force of the first spring 38, and the pressure rod 82 is simultaneously subjected to the rebound force of the second spring 84, thereby maintaining the positioning and clamping of the stamping part raw material, and at the same time, it will not cause extrusion damage caused by excessive pressure. As the stamping block 35 continues to descend, the stamping groove 6 is cooperated to perform stamping and forming operations on the stamping part raw material, thereby ensuring a good stamping effect and avoiding possible damage to the clamping part.

[0045] Embodiment three:

[0046] This embodiment aims to address the problem that in the prior art, after the stamping and forming operation of the LED display back panel stamping and forming equipment, the stamped parts are difficult to be quickly taken out and collected, and manual labor or other equipment are required to collect the stamped parts.

[0047] like Figure 8As shown, the embodiment is a stamping and forming device for the back panel of an LED display, and a demolding assembly 7 is installed inside the stamping groove 6. The demolding assembly 7 includes a support plate 75 arranged inside the base 1 at a position corresponding to the lower part of the stamping groove 6, and stripping modules 73 penetrating and extending to the outside of the stamping groove 6 are symmetrically fixed on both sides of the support plate 75. The position of the stripping module 73 is provided inside the stamping groove 6, and a slot is provided at the position corresponding to the stripping module 73. The front and rear ends of the support plate 75 are rotatably connected to a pair of connecting rods 74, and the support plate 75 is lifted and lowered by the swing of the connecting rod 74. The bottom of the connecting rod 74 is rotatably connected to a screw sleeve 77, and the interiors of the two screw sleeves 77 at the same end are commonly penetrated by a bidirectional screw rod 76 rotatably connected to the inside of the base 1. The outer layers of the two sides of the bidirectional screw rod 76 are symmetrically sleeved and fixed with second bevel gears 72, and the upper part of the second bevel gear 72 is meshingly connected with a first bevel gear 71, and the top of the first bevel gear 71 is fixed to the bottom of the screw rod 36.

[0048] During stamping, the screw rod 36 rotates and drives the bidirectional screw rod 76 to rotate. The rotation of the bidirectional screw rod 76 drives the two screw sleeves 77 to move in opposite directions. As the two screw sleeves 77 move in opposite directions, the connecting rod 74 is driven to change to a "one" shape, thereby driving the support plate 75 to descend. As the support plate 75 descends, the stripping module 73 is received into the base 1, and then the stamping block 35 cooperates with the stamping groove 6 to perform stamping and forming operations on the stamping part raw material.

[0049] When the stamping is completed, the first motor 33 is started to rotate in the opposite direction. At this time, the screw rod 36 rotates in the opposite direction to drive the stamping block 35 to rise, and at the same time drives the bidirectional screw rod 76 to rotate in the opposite direction, thereby driving the two screw sleeves 77 to move relative to each other, thereby driving the support plate 75 to rise. The lifting of the support plate 75 drives the stripping module 73 to rise, and pushes the formed stamping parts out of the stamping groove 6 to form a quick demoulding effect. With the subsequent continuous feeding, the formed stamping parts are pushed out by the subsequent stamping parts raw materials for easy collection. A collection box is fixed on the other side of the base 1 corresponding to the direction in which the stamping parts raw materials are pushed out, which can be collected manually or through a collection box.

[0050] Working process and principle of the present invention:

[0051] Step 1: stack the stamping parts raw materials inside the feed port 22, then start the second motor 51 to cooperate with the third chain 58 and the third sprocket 55 to drive the cam 54 and the grinding wheel 23 to rotate, the rotation of the cam 54 drives the shift block 57 to rotate, thereby intermittently shifting the ratchet 56 to rotate, and the ratchet 56 drives the rotating drum 25 to form intermittent movement. With the continuous movement of the rotating drum 25, the discharge cavity 24 and the feed port 22 form a docking effect, and the stamping parts raw materials enter the discharge cavity 24, and continue to move with the rotating drum 25, and finally fall to the upper surface of the conveyor crawler 13 through the discharge port 21. At the same time, during the rotation of the stamping parts raw materials, when it rotates to the position of the grinding wheel 23, the grinding wheel 23 is used to grind the bottom of the stamping parts raw materials to ensure that the stamping parts raw materials are in a horizontal state during the subsequent stamping process, thereby improving the overall stamping forming effect;

[0052] During the rotation of the ratchet 56, the second sprocket 52 and the second chain 53 drive the two rotating rollers 11 to rotate, thereby driving the conveyor belt 13 to move. When the stamping material falls onto the conveyor belt 13, the conveyor belt 13 slowly moves to the position of the support frame 4, and is pushed by the limit plate 12 to completely move into the support frame 4.

[0053] Step 2: After the stamping raw material enters the support frame 4, the first motor 33 is started to cooperate with the first sprocket 32 ​​and the first chain 31 to drive the two screw rods 36 to rotate, and the rotation of the screw rods 36 drives the lifting plate 34 to descend, and the lowering of the lifting plate 34 drives the stamping block 35 to descend, thereby performing a stamping operation on the stamping raw material;

[0054] During the descent of the lifting plate 34, the pressure blocks 37 on both sides will first contact the pressure rod 82, and as the lifting plate 34 continues to press down, the pressure rod 82 is pressed down. As the pressure rod 82 descends until it contacts the stamping part raw material, the pressure block 37 is moved toward the inside of the accommodating groove 310 by the rebound force of the pressure rod 82. During the movement, the pressure block 37 is pressed against the pressure rod 82 by the rebound force of the first spring 38, and the pressure rod 82 is pressed against the rebound force of the second spring 84, so as to keep the stamping part raw material in position and clamped, and at the same time, it will not cause extrusion damage caused by excessive pressure. As the stamping block 35 continues to descend, the stamping groove 6 is cooperated to perform stamping and forming operations on the stamping part raw material, ensuring a good stamping effect and avoiding possible damage to the clamping part.

[0055] Step 3: When stamping, the screw rod 36 rotates and drives the bidirectional screw rod 76 to rotate. The rotation of the bidirectional screw rod 76 drives the two screw sleeves 77 to move back to each other. As the two screw sleeves 77 move back to each other, the connecting rod 74 is driven to change to a "one" shape, thereby driving the support plate 75 to descend. As the support plate 75 descends, the stripping module 73 is received into the base 1, and then the stamping block 35 cooperates with the stamping groove 6 to perform stamping and forming operations on the stamping part raw material;

[0056] During stamping, the screw rod 36 rotates and drives the bidirectional screw rod 76 to rotate. The rotation of the bidirectional screw rod 76 drives the two screw sleeves 77 to move in opposite directions. As the two screw sleeves 77 move in opposite directions, the connecting rod 74 is driven to change to a "one" shape, thereby driving the support plate 75 to descend. As the support plate 75 descends, the stripping module 73 is received into the base 1, and then the stamping block 35 cooperates with the stamping groove 6 to perform stamping and forming operations on the stamping part raw material.

[0057] When the stamping is completed, the first motor 33 is started to rotate in the opposite direction. At this time, the screw rod 36 rotates in the opposite direction to drive the stamping block 35 to rise, and at the same time drives the bidirectional screw rod 76 to rotate in the opposite direction, thereby driving the two screw sleeves 77 to move relative to each other, thereby driving the support plate 75 to rise. The lifting of the support plate 75 drives the stripping module 73 to rise, and pushes the formed stamping parts out of the stamping groove 6 to form a quick demoulding effect. With the subsequent continuous feeding, the formed stamping parts are pushed out by the subsequent stamping parts raw materials for easy collection. A collection box is fixed on the other side of the base 1 corresponding to the direction in which the stamping parts raw materials are pushed out, which can be collected manually or through a collection box.

[0058] In summary, the stamping parts raw materials are stored through the feeding box 2, and the feeding component 5 is used to form an orderly and continuous feeding effect for the stamping parts, maintaining stable feeding and avoiding human interference. The stamping component 3 is used to perform stamping and forming operations on the stamping parts raw materials. At the same time, the positioning component 8 is used to form an adaptive positioning effect for stamping parts raw materials of different specifications, maintaining the stability of subsequent stamping, and the demoulding component 7 is used to form a quick demoulding effect for the stamped parts after forming, thereby forming an integrated and continuous stamping and forming process, reducing human interference and reducing possible safety hazards.

[0059] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
