[0045] In order to make the above features and advantages of the present invention more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.
[0046] As Figures 1-12 shown, this embodiment provides a new type of LED bracket, including an LED bracket plate 1 and two groups of LED lamp socket groups 2.

The upper shell 2121 is in a frame shape. The conductive plate 211 is located between the upper shell 2121 and the lower shell 2122. Four pins 2111 are respectively formed on both sides of the conductive plate 211, and the four pins 2111 are symmetrically distributed on both sides of the conductive plate 211. Two relief holes are respectively formed on two side walls of the lower shell 2122. The lower shell 2122 is formed with a receiving notch 21221, and the number of the receiving notches 21221 is 4.

The pins 2111 extend out from the relief holes, and the surfaces of the pins 2111 are attached to the outer side wall of the lower shell 2122 and are located in the receiving notch 21221. The conductive plate 211 of the lamp housing seat 21 is fixedly arranged between the upper shell 2121 and the lower shell 2122, and the pins 2111 extend out from the lower shell 2122 and are then clamped in the receiving notch 21221, which can make the connection between the conductive plate 211 and the upper shell 2121 and the lower shell 2122 more firm, and the stability of the lamp housing seat 21 is higher.
[0048] This embodiment also provides a production process for a new type of LED bracket, including the following steps:
[0049] (S1) Stamping a copper strip to form a plurality of conductive plates 211 and pins 2111;
[0050] (S2) Electroplating the copper strip;
[0051] (S3) Injecting plastic into the conductive plate 211 to form the lamp housing seat 21;
[0052] (S4) Punching and bending the pins 2111, and cutting the copper sheet to form an LED bracket;
[0053] (S5) Packing the LED bracket.
[0054] In step ( S1 ), a punching device 3 is used for punching. The punching device 3 includes a first unwinding roller 31 , a punching machine 32 and a first winding mechanism 33 .
[0055] The first unwinding roller 31 is located at the input end side of the punching machine 32, and the first winding mechanism 33 is located at the output end side of the punching machine 32. Specifically, the punching machine 32 is located in an isolation box, and the isolation box forms a first copper strip inlet and a first copper strip outlet.
[0056] The first winding mechanism 33 includes a carrying frame, a first winding rotating roller 331, a first diaphragm driven roller 332, a first tensioning column 333 and a second tensioning column 334. The copper strip passes through the first tensioning column 333 and is wound onto the first winding rotating roller 331. The first diaphragm driven roller 332 has a diaphragm roll. Specifically, the diaphragm roll is sulfur-free paper. The diaphragm roll passes around the second tensioning column 334 and is in contact with the copper strip and is wound onto the first winding rotating roller 331. The first winding rotating roller 331 is connected to the carrying frame and is driven by a motor to rotate. 31 is wound up, the first diaphragm driven roller 332 is rotatably connected to the supporting frame and is located on the upper left of the first winding rotating roller 331, and a plurality of first connecting holes and second connecting holes arranged vertically at intervals are formed on the supporting frame. The first tensioning column 333 is detachably rotatably connected to the first connecting hole, and the adjustment of the tensioning force is achieved by connecting the first tensioning column 333 to different first connecting holes. The second tensioning column 334 is detachably rotatably connected to the second connecting hole, and the adjustment of the tensioning force is achieved by connecting the second tensioning column 334 to different second connecting holes.
[0057] The step (S2) adopts the electroplating technology in the prior art.
[0058] In step ( S3 ), an injection molding device 4 is used for injection molding. The injection molding device 4 includes a second unwinding roller 41 , a first traction roller 42 , a first pushing component 43 , an injection mold 44 , a telescopic clamping mechanism 45 and a second winding rotating roller 46 .
[0059] The injection mold 44 includes a front mold 441, a middle mold 442 and a rear mold 443. On the side of the front mold 441 facing the middle mold 442, a first sliding groove and 4 first guiding holes 4411 are formed. A moving suction seat 4412 is formed in the first sliding groove, and the moving suction seat 4412 is slidably connected to the first sliding groove. Specifically, a plurality of suction holes are formed on the moving suction seat 4412. The front mold 441 is formed with a mating post 4413, and a deformation sleeve 44131 is sleeved and fixed on the surface of the mating post 4413. Limiting grooves 4414 are formed on two side walls of the front mold 441. First guiding plates 4421 are connected to both sides of the middle mold 442. One end of the first guiding plate 4421 is fixedly connected to the middle mold 442, and the other end of the first guiding plate 4421 extends into the limiting groove 4414 and is slidably connected. On the side of the middle mold 442 facing the rear mold 443, an insertion groove is formed. The middle mold 442 is formed with 4 second guiding holes 4422, and the middle mold 442 is formed with 4 mating holes 4423. The mating holes 4423 are adapted to the deformation sleeve 44131, and the diameter of the deformation sleeve 44131 is larger than that of the mating holes 4423. On the side of the rear mold 443 facing the middle mold 442, two protruding injection areas are formed. The two injection areas are arranged at intervals left and right and can enter or move away from the insertion groove. On the side of the rear mold 443 facing the middle mold 442, 4 guiding columns 4431 are formed. The 4 guiding columns 4431 respectively pass through the 4 second guiding holes 4422. A positioning ring 44311 is connected to the end of the guiding column 4431 passing through the second guiding hole 4422. The diameter of the first guiding hole 4411 is larger than or equal to the diameter of the positioning ring 44311. The 4 guiding columns 4431 are respectively adapted to the first guiding holes 4411. During stamping, the mating post 4413 and the deformation sleeve 44131 extend into the mating holes 4423, and the deformation sleeve 44131 deforms, generating a large frictional force between the deformation sleeve 44131 and the mating holes 4423. When the mold is opened and the first pushing component 43 pulls the front mold 441 back, due to the large frictional force between the deformation sleeve 44131 and the mating holes 4423, the middle mold 442 will move along with the front mold 441 until the middle mold 442 abuts against the positioning ring 44311 on the guiding column 4431. Then, the front mold 441 is separated from the middle mold 442 under the pulling of the first pushing component 43. Specifically, a spring 4432 is sleeved on the guiding column 4431, and the spring 4432 is located between the middle mold 442 and the rear mold 443. When the middle mold 442 and the rear mold 443 are opened, the spring 4432 can generate a pushing force on the middle mold 442, making the mold opening faster.
[0060] The first pushing component 43 is used to push the front mold 441 to seal with the middle mold 442 and the rear mold 443. Specifically, the first pushing component 43 is an oil cylinder, and the output end of the first pushing component 43 is fixedly connected to the front mold 441.
[0061] The copper strip sequentially passes through between the second unwinding roller 41, the first traction roller 42, the front die 441 and the middle die 442, and the second winding rotating roller 46. Specifically, the second unwinding roller 41 is a driven roller, the first traction roller 42 is also a driven roller, and the second winding rotating roller 46 is a driving roller. The copper strip is wound around the second unwinding roller 41, pulled out from the second unwinding roller, placed on the upper surface of the first traction roller 42, then passes through between the front die 441 and the middle die 442, and finally winds around the second winding rotating roller 46.
[0062] The telescopic clamping mechanism 45 is used to clamp the waste on the surface of the rear die 443. Specifically, the telescopic clamping mechanism 45 includes a first cylinder 451, a second cylinder 452 and an opposing clamping assembly 453.
[0063] The second cylinder 452 is connected to the output end of the first cylinder 451, and the opposing clamping assembly 453 is connected to the output end of the second cylinder 452.
[0064] The opposing clamping assembly 453 includes a third cylinder 4531, two extension plates 4532, a first connecting rod 4533, a second connecting rod 4534, a third connecting rod 4535 and a fourth connecting rod 4536. The third cylinder 4531 includes a cylinder body and an output rod. The two extension plates 4532 are connected to both sides of the lower surface of the cylinder body. The orientations of the two extension plates 4532 are perpendicular to the clamping direction. One end of the first connecting rod 4533 is rotatably connected to the output rod, and the other end of the first connecting rod 4533 is rotatably connected to one end of the third connecting rod 4535. One end of the second connecting rod 4534 is rotatably connected to the output rod, and the other end of the second connecting rod 4534 is rotatably connected to one end of the fourth connecting rod 4536. The third connecting rod 4535 and the fourth connecting rod 4536 are hinged by a first rotating shaft. The first rotating shaft is fixedly arranged between the two extension plates 4532. Clamping bodies 4537 are formed on the surfaces of the third connecting rod 4535 and the fourth connecting rod 4536 facing the lower die. The clamping action is realized through the cooperation of the third cylinder 4531 and the connecting rods. Specifically, a second sliding groove 45321 is formed on the facing surfaces of the two extension plates 4532. The second sliding groove 45321 is horizontally arranged. The first connecting rod 4533 and the third connecting rod are rotatably connected by a second rotating shaft. First rotating wheels 4538 are formed at both ends of the second rotating shaft. The first rotating wheels 4538 are located in the second sliding groove 45321 and are slidably connected.

The second rotating wheels 4539 are located in the second sliding groove 45321 and are slidably connected. The cooperation of the first rotating wheels 4538 and the second sliding groove 45321 and the cooperation of the second rotating wheels 4539 and the second sliding groove 45321 make the opposing clamping action of the clamping bodies 4537 more stable and powerful.
[0065] Among them, in step (S4), a press of the prior art is used to bend the copper strip pins 2111, and a slitter of the prior art is used to slit the copper strip into individual LED brackets.
[0066] The specific operation steps are as follows: First, the copper strip is pulled out from the first unwinding roller 31, stamped by the stamping machine 32, and then passes through the first tensioning post 333. The diaphragm is pulled out from the first diaphragm driven roller 332, passes through the second tensioning post 334, and is attached above the copper strip passing through the first tensioning post 333. Finally, the diaphragm and the copper strip are wound together by the first winding rotating roller 331; then the stamped copper strip is electroplated; then, the copper strip is pulled out from the second unwinding roller 41, passes through the first traction roller 42, and when passing through the front mold 441 and the rear mold 443, the moving adsorption seat 4412 on the front mold 441 extends to adsorb and position the copper strip and then retracts. The first pushing assembly 43 closes the front mold 441, the middle mold 442, and the rear mold 443. The liquid material is injected into the middle mold 442 from the rear mold 443. After shaping, the front mold 441, the middle mold 442, and the rear mold 443 are opened. The moving adsorption seat 4412 releases the copper strip, and the second winding rotating roller 46 rotates to pull the copper strip downward. The telescopic clamping mechanism extends between the middle mold 442 and the lower mold and clamps out the waste between the lower molds. Then the above actions are repeated until an entire roll of copper strip is injection molded; then the injection-molded copper strip is bent into pins 2111 by the stamping machine 32 and slit by the slitter. At this time, the LED bracket is already formed. Finally, the LED bracket is manually packaged.
