Description

Technical Field

[0001] This invention relates to the field of LED lamp bead bracket processing technology, specifically to a post-processing method for LED lamp bead bracket injection molding. Background Technology

[0002] LED lamp bead brackets are mainly used for the conduction and support of LEDs. Their basic structure consists of an electroluminescent semiconductor material chip, which is cured onto the bracket with silver or white glue, and connected to the circuit board with silver or gold wires. Then, the surrounding area is sealed with epoxy resin to protect the internal core wires. Finally, the outer shell is installed. Therefore, LED lights have good shock resistance and are used in mobile phones, desk lamps, home appliances and other daily appliances as well as in machinery manufacturing.

[0003] Because LED bead holders are small in size, multiple neatly arranged LED bead holders are usually processed at once to form a workpiece. Finally, the individual LED bead holders are separated from the outer contour of the workpiece. During the separation process, the workpiece needs to be manually placed into the processing mold, so the separation efficiency of LED bead holders is low. In addition, since the LED bead holders need to undergo workpiece separation and bending processes, multi-station processing is required. However, during the processing, the LED bead holders are very easy to move under force, resulting in large dimensional errors in the processing of the LED bead holders, ultimately leading to low processing quality of the LED bead holders.

[0020] The present invention has the following beneficial effects: 1. The present invention provides a post-processing method for LED lamp bead bracket injection molding, which improves processing efficiency by transporting and positioning the lamp bead bracket molded part through a positioning unit, and separates the lamp bead bracket from the workpiece through a processing unit, while bending the lamp bead bracket.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] See Figure 1 and Figure 10 A method for post-processing of LED bead holders after injection molding is disclosed. This method utilizes a post-processing device for LED bead holders after injection molding, which includes a positioning unit 1 and a processing unit 2. The specific method for post-processing the injection-molded LED bead holders using this device is as follows:

[0037] S1. Transporting the molded part: First, the lamp bead bracket molded by the positioning unit 1 is transported to the right so that it can move smoothly to the bottom of the processing unit 2.

[0038] S2. Processing: The lamp bead bracket molding part is processed by processing unit 2 to separate the lamp bead bracket from the molding frame;

[0039] S3. Collect the workpiece: Collect the separated lamp bead brackets through processing unit 2;

[0040] S4. Waste collection: The molded frame is squeezed to the right by the lamp bead bracket molded part on the left, and is eventually collected for recycling.

[0041] The positioning unit 1 is fixedly mounted with a processing unit 2.

[0042] See Figure 1 The positioning unit 1 includes a positioning platform 11, on which a belt conveyor 12 is fixedly mounted. Multiple abutment blocks 13 are uniformly fixedly mounted on the outer end face of the belt conveyor 12. Fixed plates 14 are symmetrically fixedly mounted on the upper end of the positioning platform 11. A bidirectional threaded rod 15 is rotatably connected between the fixed plates 14. The bidirectional threaded rod 15 has threaded grooves with opposite directions of rotation on its front and rear sides. A motor 16 is fixedly mounted on the front end of the fixed plate 14 via a motor mount. The output shaft of the motor 16 is fixedly connected to the bidirectional threaded rod 15 via a coupling. Limiting moving parts 17 located between the fixed plates 14 are symmetrically rotatably connected to the bidirectional threaded rod 15. Rubber buffer blocks 18 are fixedly mounted on the opposite end faces of the limiting moving parts 17. Two sliding guide rods 19 that penetrate the limiting moving parts 17 are fixedly mounted on the opposite end faces of the fixed plates 14. A trapezoidal groove is provided on the right side, and a material discharge through hole is provided at the lower end of the trapezoidal groove. A collection rack 20 is engaged at the lower end of the material discharge through hole. First, the injection-molded lamp bead bracket is placed on the belt conveyor 12. The motor 16 drives the bidirectional threaded rod 15 to rotate, thereby driving the limiting moving parts 17 on the front and rear sides to move towards each other, so that the rubber buffer on the limiting moving parts 17 is in close contact with the front and rear ends of the lamp bead bracket, thereby positioning it. The abutment block 13 on the belt conveyor 12 squeezes the left end of the lamp bead bracket, so that it moves smoothly to the right with the belt conveyor 12. The material discharge through hole is compensated by the processing unit 2. The lamp bead bracket moves to the processing unit 2 below the material discharge through hole. The processing unit 2 processes the lamp bead bracket and the processing lamp bead bracket is collected by the collection rack 20.

[0043] See Figure 1 , Figure 2 , Figure 3 and Figure 5The processing unit 2 includes a support plate 21. An L-shaped support plate 21 with a horizontal section directly above the material discharge hole is mounted on the upper end of the positioning platform 11. A processing cylinder 22 is fixedly mounted on the lower end of the horizontal section of the support plate 21. A rectangular plate 23 is fixedly mounted on the lower end of the processing cylinder 22. Multiple processing groups are evenly mounted on the lower end of the rectangular plate 23. Each processing group consists of two right-angled blocks 24 arranged symmetrically with their concave surfaces facing each other. A material discharge blade 25 is fixedly mounted on the opposite side of each right-angled block 24 within each processing group. The front and rear adjacent blanking blades 25 are fixedly connected. Limiting springs 26 are fixedly installed between the right-angled blocks 24 at the lower end of the rectangular plate 23 within each processing group. Circular abutments 27 are fixedly installed at the lower end of the limiting springs 26. Cutting blades 28 are fixedly installed on both sides of the circular abutments 27 at the lower end of the rectangular plate 23. An L-shaped bracket 29 is fixedly installed below the blanking through hole. A forming cylinder 30 is fixedly installed at the upper end of the horizontal section of the L-shaped bracket 29. A tilting frame 3 is fixedly installed at the upper end of the forming cylinder 30. 1. Multiple mating forming parts 32 are evenly fixedly installed on the upper end of the flipping frame 31. The forming cylinder 30 drives the mating forming parts 32 to move upward until the upper end of the mating forming parts 32 is flush with the upper end of the blanking through hole. When the lamp bead bracket forming part moves onto the mating forming part 32 in the blanking through hole, the processing cylinder 22 drives the rectangular plate 23 to move downward. The circular abutment 27, driven by the limit spring 26, first contacts the upper end of the lamp bead bracket to position it. Then the blanking knife 25 forms the lamp bead bracket. Upon contact with the component, the individual LED bead bracket is unloaded. Then, the rectangular plate 23 continues to move downwards, and the right-angled block 24 contacts the individual LED bead bracket. With the cooperation of the right-angled block 24 and the mating forming part 32, the individual LED bead bracket is bent. At the same time, the cutting blade 28 separates the front and rear ends of the individual LED bead bracket from the forming part. After processing, the separated individual LED bead bracket falls onto the mating forming part 32. Finally, as the upper surface of the flipping frame 31 tilts, the LED bead bracket falls downwards into the collecting rack 20.

[0044] See Figure 2 The collection rack 20 includes a rectangular tube 201, with the lower end of the material discharge hole clamped to the rectangular tube 201. An L-shaped bracket 29 is located inside the rectangular tube 201, and a collection box 202 is clamped to the lower end of the rectangular tube 201. A mesh screen plate 203 is fixedly installed inside the lower side of the rectangular tube 201. When the lamp bead bracket falls onto the mesh screen plate 203, the mesh screen plate 203 filters the processed debris attached to the lamp bead bracket, and the collection box 202 collects the debris. The collection box 202 cooperates with the rectangular tube 201 to collect the lamp bead bracket.

[0045] See Figure 3The right-angled block 24 includes a rectangular post 241. In each processing group, a square post 242 is fixedly installed on the opposite end face of the rectangular post 241. The front and rear ends of the square post 242 are fixedly connected to a limiting baffle 243. A plurality of balls 244 are evenly rolled on the end of the limiting baffle 243 away from the square post 242. The left and right ends of the lamp bead bracket are formed by the cooperation of the rectangular post 241 and the square post 242. The front and rear sides of the lamp bead bracket are limited by the limiting baffle 243. The frictional resistance between the limiting baffle 243 and the lamp bead bracket is reduced by the balls 244.

[0046] Continue reading Figure 3 Multiple inclined scraper blades 251 are uniformly fixedly installed on the upper side of the blanking blade 25 and near the end of the circular abutment 27; the inclined scraper blades 251 are used to scrape off the burrs on the cut surface of the lamp bead bracket.

[0047] See Figure 3 , Figure 7 and Figure 8 The circular abutment 27 has a circular groove 271 on its lower end face. A limiting ring 272 is fixedly installed on the lower end face of the circular groove 271. A buffer rubber 273 is fixedly installed on the outer end face of the limiting ring 272. A compression spring 274 is fixedly installed in the middle of the upper inner wall of the circular groove 271. A compression round piece 275 is fixedly installed at the lower end of the compression spring 274. When the rectangular plate 23 moves downward, it extends into the annular groove at the upper end of the lamp bead bracket through the limiting ring 272, thereby adjusting the lamp bead bracket. Positioning and pressing the extrusion round part 275 presses the middle of the upper end face of the lamp bead bracket under the action of the extrusion spring 274, further restricting the degree of freedom of the lamp bead bracket during the cutting process. The buffer rubber 273 prevents the metal coating at the upper end of the lamp bead bracket from being scratched. When the rectangular plate 23 moves upward, the limiting ring 272 separates from the annular groove at the upper end of the lamp bead bracket first. The extrusion round part 275 then separates from the lamp bead bracket under the action of the extrusion spring 274, preventing the lamp bead bracket from being lifted by the limiting ring 272.

[0048] See Figure 5 and Figure 7 The cutting blade 28 includes an arc-shaped separating blade 281. The lower end of the rectangular plate 23 and both the front and rear sides of the circular abutment 27 are fixedly installed with arc-shaped separating blades 281. The opposite end faces of the arc-shaped separating blades 281 on the front and rear sides are rolled with abrasive balls 282. The arc-shaped separating blades 281 separate the lamp bead bracket from the molded part, and the abrasive balls 282 polish the cut on the lamp bead bracket to make its surface smooth.

[0049] See Figure 5The flipping frame 31 includes a fixed circular plate 311 installed at the pushing end of the forming cylinder 30. A second motor 312 is fixedly installed at the front end of the fixed circular plate 311 via a motor base. A bevel gear 313 is fixedly installed at the output shaft of the second motor 312. A rotating cylinder 314 is rotatably connected to the front end of the fixed circular plate 311. Multiple mating forming parts 32 are evenly fixedly installed on the upper surface of the rotating cylinder 314. A semi-annular mating groove 315 is opened at the rear end of the rotating cylinder 314. Conical tooth grooves 316 are evenly opened along the circumference of the semi-annular mating groove 315. The conical tooth grooves 316 and the bevel gear 313 are mated. The second motor 312 drives the bevel gear 313 to rotate, thereby driving the rotating cylinder 314 to rotate 180 degrees, so as to drive the mating forming parts 32 to flip downward, so that the lamp bead bracket can fall downward smoothly.

[0050] See Figure 4 , Figure 6 , Figure 8 and Figure 9 The forming component 32 includes two L-shaped forming components 321 arranged symmetrically on the left and right with their concave surfaces facing away from each other. A blanking forming component 322 is fixedly installed on the opposite side of each L-shaped forming component 321. A blanking forming groove 323 is opened in the middle of the blanking forming component 322. Arc-shaped forming components 324 are fixedly installed at both ends of the two L-shaped forming components 321. The L-shaped forming component 321 cooperates with the right-angle block 24 to shape the lamp bead bracket. The blanking forming groove 323 on the blanking forming component 322 cooperates with the blanking knife 25 to blank the lamp bead bracket. The arc-shaped forming component 324 cooperates with the arc-shaped separating knife 281 to smoothly separate the lamp bead bracket from the forming component.
