Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp processing devices, in particular to a thresher. Background Art

[0002] In order to ensure the mechanical strength and light transmittance of LEDs during use, the LED chips need to be packaged. Existing LED packages generally include a base, pins, a heat sink, a chip, a phosphor layer, a filler and a plastic lens. If a single chip is packaged, the efficiency is low and the packaging quality is unstable.

[0003] In the process of LED packaging, it is necessary to detach the LED lamp beads from the LED bracket and then package them. The existing threshing device, as described in the utility model with publication number CN206953164U and name of a LED stripping machine blanking device, includes a knife die fixing seat and a knife die. The knife die fixing seat is divided into an upper die seat and a lower die seat, and a vertical flat key and a key groove are used between the upper die seat and the lower die seat.

[0004] In actual use of the above device, because the tooth edges on the upper hob and the lower hob used for stripping are vertically distributed, the operator is often required to adjust the position of the LED bracket multiple times during the processing until it is aligned with the gap between the tooth edges on the upper hob and the lower hob to effectively process and detach the LED bracket. This not only has low processing efficiency, but also easily damages the LED lamp beads due to manual thrust. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a thresher for solving the technical problems in the background art that the existing thresher has low processing efficiency and is prone to damage to LED lamp beads.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example:

[0022] Reference Figure 1 to Figure 3 The device is a thresher, comprising an upper mounting frame 1 and a lower mounting frame 2, wherein the upper mounting frame 1 is detachably mounted on the top of the lower mounting frame 2 in a floating manner, mounting holes 10 are provided on both sides of the upper mounting frame 1, mounting slots 11 corresponding to the two mounting holes 10 are provided on the lower mounting frame 2, a pin rod 12 with a top cap is provided in each of the mounting holes 10, each of the pin rods 12 slides through the mounting hole 10 and slides into the corresponding mounting slot 11, each of the pin rods 12 is detachably connected to the mounting slot 11, and a buffer spring 13 is provided between the top cap of each of the pin rods 12 and the mounting hole 10. Fixing holes 14 penetrating the mounting slot 11 are provided on both sides of the lower mounting frame 2, each of the fixing holes 14 is provided with a connecting bolt 15, each of the connecting bolts 15 is threaded through the pin rod 12 extending into the mounting slot 11 and extends outwards, and a plurality of connecting nuts 16 for fixing the connecting bolts 15 are provided on the side wall of the lower mounting frame 2. This arrangement can effectively compress the upper mounting frame 1 toward the lower mounting frame 2 by the elasticity of the buffer spring 13, and can always maintain a downward pressure while keeping the upper mounting frame 1 for vertical adjustment and sliding. The plurality of pin rods 12 can be further fixed in the mounting groove 11 by the provided connecting bolts 15 and connecting nuts 16 to prevent the upper mounting frame 1 from being separated from the lower mounting frame 2 during processing.

[0023] like Figure 2 and Figure 3 As shown, the upper roller cutter 3 and the lower roller cutter 4, the upper roller cutter 3 is rotatably mounted between the upper mounting frame 1, and the lower roller cutter 4 is rotatably mounted between the lower mounting frame 2. The outer wall of the upper roller cutter 3 is evenly and obliquely provided with a plurality of first ridges 5, and a first groove 6 is formed between each of the first ridges 5. The outer wall of the lower roller cutter 4 is evenly and obliquely provided with a plurality of second ridges 7, and a second groove 8 is formed between each of the second ridges 7. A plurality of the first ridges 5 extend into a plurality of the second grooves 8 in a one-to-one correspondence, and a plurality of the second ridges 7 extend into a plurality of the first grooves 6 in a one-to-one correspondence. Because the first ridge 5 and the second ridge 7 are both obliquely arranged, and the first groove 6 and the second groove 8 are respectively arranged between them, the squeezed lamp beads can enter the first groove 6 or the second groove 8 to be detached. The first groove 6 and the second groove 8 are arranged, and the force of the first ridge 5 and the second ridge 7 squeezing the LED lamp beads can just be the lamp beads entering the first groove 6 and the second groove 8.

[0024] like Figure 2 As shown, it includes a driving assembly, which is located between the upper roller cutter 3 and the lower roller cutter 4 and is used to drive the upper roller cutter 3 and the lower roller cutter 4 to rotate relative to each other. The driving assembly includes an upper connecting rod 17, a lower connecting rod 18 and two connecting gears 19. The upper connecting rod 17 is coaxial with the upper roller cutter 3 and is fixedly connected to one end of the upper roller cutter 3. The lower connecting rod 18 is coaxial with the lower roller cutter 4 and is fixedly connected to one end of the lower roller cutter 4. The two connecting gears 19 are fixedly mounted on the upper connecting rod 17 and the lower connecting rod 18 respectively, and the two connecting gears 19 are meshed with each other. This arrangement can effectively drive the upper connecting rod 17 or the lower connecting rod 18 to rotate through an external power source such as a motor. When the upper connecting rod 17 or the lower connecting rod 18 rotates, it will further drive the two connecting gears 19 to mesh and rotate, and drive the upper roller cutter 3 and the lower roller cutter 4 to rotate relative to each other.

[0025] like Figure 1 As shown, it includes a feeding assembly, which is located between the upper mounting frames 1 and is used to transport the LED brackets between the upper roller cutter 3 and the lower roller cutter 4. The feeding assembly includes two rotating shafts 20 and a conveyor belt 21. The two rotating shafts 20 are parallel to the upper roller cutter 3 and are rotatably installed between the upper mounting frames 1. The conveyor belt 21 is sleeved between the two rotating shafts 20, and the conveyor belt 21 is also provided with a plurality of protrusions 22. The collecting bin 9 is located between the lower mounting frames 2 and below the lower roller cutter 4. The collecting bin 9 is used to collect the separated LED lamp beads. Cleaning brushes 23 are respectively provided on the upper mounting frame 1 and the lower mounting frame 2. A bracket guide plate 24 is provided on the lower mounting frame 2 and on the side of the lower roller cutter 4 away from the feeding assembly. The bracket guide plate 24 is used to facilitate the discharge of the separated LED brackets, and can also be collected by arranging a collection box at the end of the bracket guide plate 24.

[0026] Working principle:

[0027] When in use, firstly, the upper roller cutter 3 and the lower roller cutter 4 are driven by the driving assembly to rotate relative to each other, and the LED bracket is placed on the conveyor belt 21. Then, the two rotating shafts 20 are driven to rotate and the conveyor belt 21 and the LED bracket on the conveyor belt 21 are driven to move. When the LED bracket is close to the upper roller cutter 3 and the lower roller cutter 4, the LED bracket can be easily entered between the upper roller cutter 3 and the lower roller cutter 4 through the abutment between the protrusion 22 on the conveyor belt 21 and the LED bracket. Because the first convex ridge 5 and the second convex ridge 7 on the upper roller cutter 3 and the lower roller cutter 4 are both obliquely arranged, there is no need to deliberately limit the entry position of the LED bracket to detach the lamp beads on the LED bracket. The detached LED lamp beads will enter the collection bin 9 with the rotation of the upper roller cutter 3 and the lower roller cutter 4 and the scraping of the cleaning brush 23, and the processed LED bracket will be discharged along the bracket guide plate 24.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
