Description

Technical Field

[0001] This application relates to the field of feeding device technology, and in particular to a lamp bead feeding structure. Background Technology

[0002] An LED chip feeder is a device used to transport LED chips to corresponding equipment, and it is usually configured and used in conjunction with a pick-and-place machine. A typical LED chip feeder includes a circular vibrator, a linear vibrator, a robotic arm for handling, and a transport track. During operation, the LED chips are sequentially fed to the robotic arm by the circular and linear vibrators. The robotic arm lifts the chips and moves them to the transport track, which is connected to the subsequent packaging and encapsulation device.

[0003] The LED chips are transported using circular and linear vibration methods. The LED chips move under continuous vibration. However, when there are other processing equipment such as machine tools in the transport environment, the vibration emitted by the processing equipment can easily resonate with the circular and linear vibration, affecting the transport of LED chips and reducing or even stopping the transport efficiency of the feeder. In addition, when changing the LED chip specifications, the end of the LED chip feeder needs to be disassembled to clean the LED chips of the previous specifications, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this application is to provide a lamp bead feeding structure, which aims to improve the problem of lamp bead feeders being susceptible to external vibration in related technologies, and increase the transportation stability and ease of use of lamp bead feeders.

[0005] This application provides a lamp bead feeding structure, including a feeding base, a transport component disposed on the feeding base, and a material channel component disposed on the transport component; the transport component includes a transport seat, a transport roller rotatably connected to the transport seat, a conveyor belt covering the transport roller, and a transport drive member for driving the transport roller; one end of the conveyor belt is provided with an end component, the end component including a lamp bead limiting block slidably connected to the feeding base, an end drive member for driving the lamp bead limiting block, and a cleaning hopper disposed below the lamp bead limiting block, the lamp bead limiting block abutting or disengaging from the conveyor belt.

[0006] Furthermore, the material channel assembly includes a material channel seat detachably connected to the transport seat; the material channel seat includes a material channel body, and a plurality of material channel limiting blocks are fixedly connected to one side of the material channel body; a conveying cavity for accommodating lamp beads is formed between adjacent material channel limiting blocks.

[0007] Furthermore, a plurality of material channel grooves are provided on the side of the material channel body away from the material channel limiting block, and the material channel grooves are provided with observation strip holes that communicate with the conveying material cavity.

[0008] Furthermore, the lamp bead limiting block has several limiting grooves connected to the conveying material cavity, and each of the limiting grooves corresponds to one of the conveying material cavities.

[0009] Furthermore, guide rods are fixedly connected to both ends of the lamp bead limiting block; the feeding base has a fixed seat for cooperating with the guide rods, and the guide rods are slidably connected to the fixed seat.

[0010] Furthermore, the end drive component includes lifting cylinders disposed on both sides of the feeding base, the lifting cylinders being located below the lamp bead limiting block and facing the lamp bead limiting block.

[0011] Furthermore, the cleaning hopper includes an end surround and a feeding tilting part fixedly connected to the end surround; the end surround is arranged around the lower part of the lamp bead limiting block.

[0012] Furthermore, the conveyor belt is a steel belt.

[0013] The beneficial effects of this application are:

[0014] 1. The LED bead feeding structure of this application includes a transport component installed on the feeding base. When the transport component is running, the transport drive unit drives the transport roller to rotate, which in turn drives the conveyor belt to rotate. The LED beads are placed on the conveyor belt, and under the limiting action of the material channel component, the LED beads are transported along the material channel component driven by the conveyor belt. Using the conveyor belt instead of vibration transport can effectively avoid the impact of vibration from other equipment on the feeding structure and ensure the transport stability of the feeding structure. At the same time, by setting an end component, the LED bead limiting block is used to limit the LED beads. When it is necessary to switch the LED bead specifications, the movable LED bead limiting block is disengaged from the conveyor belt, and the LED beads fall from the conveyor belt to the cleaning hopper for collection under the drive of the conveyor belt. There is no need to disassemble the end of the feeding structure for cleaning, which increases the convenience of the feeding structure.

[0015] 2. A lamp bead feeding structure of this application forms a conveying cavity by setting a material channel limiting block below the material channel body, and opening a material channel groove and an observation strip hole above the material channel body; the material channel limiting block limits the lamp beads for transportation; the material channel groove can reduce the weight of the material channel seat to facilitate production and reduce costs, and the transportation status of the lamp beads can be observed and monitored through the observation strip hole, so as to make rapid control according to the transportation status.

[0016] 3. The cleaning hopper is equipped with an end surround and a discharge incline. The end surround surrounds the lamp bead limiting block. When the lamp bead limiting block is raised, the lamp bead falls to the end surround and slides down the discharge incline for easy collection. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0028] Reference Figure 1 as well as Figure 2 This application provides a lamp bead feeding structure, including a feeding base 1, a transport component 2 disposed on the feeding base 1, a material channel component 3 disposed on the transport component 2, and an end component 4 disposed on the feeding base 1. When the lamp bead feeding structure is in operation, the transport component 2 drives the lamp beads to move, the material channel component 3 limits the lamp beads, and the end component 4 limits the lamp beads to facilitate transfer and cleaning.

[0029] Specifically, the feeding base 1 is horizontally positioned and is used to support and install various components. The feeding base 1 has a connecting part that facilitates installation and cooperation with other parts. The transport component 2 includes a transport seat 21, a transport roller rotatably connected to the transport seat 21, a conveyor belt 22 covering the transport roller, and a transport drive component for driving the transport roller.

[0030] In this embodiment, the transport seat 21 is positioned above the feeding base 1 and is horizontally arranged. There are two transport rollers, each rotatably connected to one end of the transport seat 21 along its length. The conveyor belt 22 is a steel belt, extending along the length of the transport seat 21, with its width sides abutting against the transport seat 21. The conveyor drive 23 is a motor, connected to one of the transport rollers via belt drive. Driven by the conveyor drive 23, the transport roller rotates, thereby rotating the conveyor belt 22. It is understood that the conveyor belt 22 can also be a belt.

[0031] The material channel assembly 3 includes a material channel seat 31 that is detachably connected to the transport seat 21. The material channel seat 31 includes a material channel body 311, and the material channel body 311 is provided with a plurality of mounting parts along the circumferential direction. The mounting parts are provided with through holes, and the mounting parts are detachably connected to the transport seat 21 by means of threaded connection, thereby realizing convenient maintenance and replacement of the material channel seat 31.

[0032] Reference Figure 3 , Figure 4 as well as Figure 5To limit the movement of the LED beads, several channel limiting blocks 312 are fixedly connected to the side of the material channel body 311 near the conveyor belt 22. These limiting blocks 312 are parallel to each other and extend along the length of the conveyor belt 22, forming a conveying cavity 3121 between adjacent limiting blocks 312 to accommodate the LED beads. The size of the conveying cavity 3121 is adapted to the size of the LED beads. When an LED bead is placed on the conveyor belt 22, it enters the corresponding conveying cavity 3121 under the influence of the conveyor belt 22 and is transported along the length of the conveying cavity 3121. By setting the channel seat 31 and the transport component 2, the LED beads are transported via the conveyor belt 22 under the limiting effect of the channel seat 31. Using the conveyor belt 22 instead of vibration transport allows the LED bead supply structure to avoid being affected by vibrations from other equipment, thereby increasing the operational stability and adaptability of the LED bead supply structure.

[0033] It is worth mentioning that several channel grooves 313 are provided on the side of the main body of the channel 311 away from the channel limiting block 312. Each channel groove 313 has an observation slot 3131 that communicates with the conveying chamber 3121. The width of the observation slot 3131 is smaller than that of the LED bead, thus preventing the LED bead from falling out of the observation slot 3131. The channel grooves 313 effectively reduce the weight of the main body of the channel 311 and production costs. The observation slots 3131 allow for convenient observation and monitoring of the LED bead in the conveying chamber 3121, facilitating operator control of the LED bead feeding structure based on the monitoring status.

[0034] An end assembly 4 is located at one end of the conveyor belt 22. The end assembly 4 includes a lamp bead limiting block 41 slidably connected to the feeding base 1, an end drive component 42 for driving the lamp bead limiting block 41, and a cleaning hopper 43 located below the lamp bead limiting block 41. The lamp bead limiting block 41 abuts against or disengages from the conveyor belt 22. Specifically, the lamp bead limiting block 41 has several limiting grooves 411 communicating with the conveying chamber 3121, with each limiting groove corresponding to one of the conveying chambers 3121. After the lamp beads move into the limiting grooves 411 driven by the conveyor belt 22, a subsequent transfer robotic arm or transfer nozzle will remove the lamp beads from the limiting grooves 411 and transfer them to the next process structure or device.

[0035] Refer to 1. Figure 2 as well as Figure 6The purpose of making the LED bead limiting block 41 movable is to facilitate the cleaning of the previous LED beads when switching LED bead specifications. In this embodiment, guide rods 412 are fixedly connected to both ends of the LED bead limiting block 41; the feeding base 1 has a fixed seat 11 for cooperating with the guide rods 412, and the guide rods 412 are slidably connected to the fixed seat 11. The end drive member 42 includes lifting cylinders disposed on both sides of the feeding base 1, the lifting cylinders being located below the LED bead limiting block 41 and facing the LED bead limiting block 41. Correspondingly, the cleaning hopper 43 includes an end surrounding portion 431 and a feeding inclined portion 432 fixedly connected to the end surrounding portion 431; the end surrounding portion 431 is disposed around the lower part of the LED bead limiting block 41.

[0036] By setting the end component 4 in this way, when switching the specifications of the transported LED beads, it is only necessary to use the end drive 42 to drive the LED bead limiting block 41 to rise. After the LED bead limiting block 41 is separated from the conveyor belt 22, the previous LED beads will fall from the conveyor belt 22 into the end surround part 431 of the cleaning hopper 43 because there is no LED bead limiting block 41 to limit them. Finally, they will slide down along the feeding inclined part 432 to the bottom of the transport seat 21 and be collected. This makes it possible to switch the specifications of LED beads without disassembling the end component 4, which effectively increases the ease of use of the LED bead feeding structure.
