Description

Technical Field

[0001] The invention relates to the technical field of LED chip processing, in particular to an automatic chip arrangement machine for LED chips. Background Art

[0002] With the rapid development of LED technology and the gradual improvement of LED light efficiency, the application of LED will become more and more extensive. With the increasing severity of the global energy shortage problem, people are paying more and more attention to the development prospects of LED in the lighting market. LED will be a potential light source to replace incandescent lamps, tungsten lamps and fluorescent lamps. The core of LED lamps is LED chips, which refers to PN junctions. Its main function is to convert electrical energy into light energy. The main material of the chip is single crystal silicon. The semiconductor wafer consists of two parts. One part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, which is mainly electrons. But when these two semiconductors are connected, a PN junction is formed between them. When the current acts on the wafer through the wire, the electrons will be pushed to the P area, where the electrons and holes recombine, and then they will emit energy in the form of photons. This is the principle of LED luminescence. When the LED chip is processed, due to its small size, the arrangement method is mostly done manually, resulting in low efficiency and low automation. For this reason, we proposed an automatic arrangement machine for LED chips. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an automatic LED chip arrangement machine that can automatically arrange chips, while preventing LED chips from bridging each other and causing poor material feeding, and can also prevent material jamming and damage to LED chips. The arrangement efficiency is higher and the problems in the background technology can be effectively solved.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic LED chip arrangement machine, comprising a mounting frame and a material distribution tray;

[0005] Mounting frame: The upper surface of the mounting frame is symmetrically provided with linear motors, and the mover seats of the two linear motors are respectively fixedly connected to the protrusions provided on the front and rear sides of the material distribution box. The upper opening of the material distribution box is provided with a feed hopper, and the lower opening of the material distribution box is provided with a discharge pipe. The input end of the linear motor is electrically connected to the output end of the external controller;

[0006] Material dividing disk: It is rotatably connected to the inside of the material dividing box, and a first motor is installed at the center of the front side of the material dividing box through a flange. The front and rear ends of the output shaft of the first motor are respectively rotatably connected to the through holes set in the middle of the front side of the material dividing box, and the middle part of the output shaft of the first motor is fixedly connected to the middle part of the material dividing disk. The input end of the first motor is electrically connected to the output end of the external controller, which can automatically arrange the chips, and at the same time prevent the LED chips from bridging each other and causing poor material feeding, and can also prevent material jamming and damage to the LED chips, so that the chip arrangement efficiency is higher.

[0007] Furthermore, the outer arc surface of the material distribution plate is evenly provided with material grooves, and the inside of the material grooves is symmetrically provided with first springs. The outer ends of the two first springs located inside the same material groove are fixedly connected to the bottom plate, and the inner wall of the upper opening of the material distribution box is symmetrically provided with inclined surfaces, which protects the LED chips.

[0008] Furthermore, rollers are connected to the inner center of the upper hopper in a symmetrically rotatable manner. The front ends of the two rollers extend to the front end of the upper hopper and a first pulley is provided at the end. The two first pulleys are connected by a belt transmission. The rear end of the roller on the right side is fixedly connected to the output shaft of the second motor provided in the middle of the rear side surface of the upper hopper. The input end of the second motor is electrically connected to the output end of the external controller to prevent material jamming.

[0009] Furthermore, a paddle is rotatably connected to the inner left end of the upper hopper, and a second spring is symmetrically arranged on the right end of the lower surface of the paddle, and the lower ends of the two second springs are fixedly connected to the inner wall on the left side of the upper hopper to prevent the LED chips inside the upper hopper from bridging each other.

[0010] Furthermore, the front end of the rotating shaft on the left side of the paddle plate extends to the outside of the upper hopper and is provided with a gear at the end. The front side of the upper hopper is rotatably connected to a mounting shaft, and the rear end of the mounting shaft is provided with a single-tooth gear that cooperates with the gear to provide driving force for the vibration of the paddle plate.

[0011] Furthermore, the mounting shaft and the front end of the roller on the left are both provided with a second pulley, and the two second pulleys are connected by a connecting belt transmission to facilitate the transmission of driving force.

[0012] Furthermore, it also includes a laser sensor, which is arranged in a mounting groove inside the discharge pipe. The output end of the laser sensor is electrically connected to the input end of an external controller to facilitate automatic film arrangement.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the LED chip automatic and efficient chip arrangement machine has the following advantages:

[0014] 1. The external controller controls the second motor to rotate, and drives the roller on the right to rotate. At the same time, the first pulley and the belt drive the roller on the left and the roller on the right to rotate counterclockwise. At the same time, the connecting belt and the second pulley drive the mounting shaft to rotate and the single-tooth gear to rotate counterclockwise. When the single-tooth gear rotates to mesh with the gear, it drives the paddle to rotate clockwise around the rotating shaft at the left end, so that the right end of the paddle presses the second spring downward. When the single-tooth gear is separated from the gear, the second spring bounces the right end of the paddle upward to prevent the LED chips from bridging each other. When there are two LED chips stuck at the lower end of the upper hopper, the two rollers rotate counterclockwise at the same time to displace the two stuck LED chips up and down to ensure normal unloading.

[0015] 2. The external controller controls the first motor at the front end of the dividing box to drive the dividing disk to rotate. When the material trough on the outer arc surface of the dividing disk corresponds to the lower end of the upper hopper, the LED chip falls into the inside of the trough and contacts the bottom plate, so that the outside of the LED chip is higher than the outer arc surface of the dividing disk to prevent two LED chips from falling into the inside of the trough at the same time, causing damage to the LED chip. The dividing disk continues to rotate, so that the outside of the LED chip inside the trough contacts the inclined surface at the upper end of the dividing box, thereby pressing the LED chip downward, and the first spring is compressed. The dividing disk continues to rotate until the LED chip corresponds to the discharge pipe. At this time, under the elastic force of the first spring, the LED chip quickly pops out through the discharge pipe to the external collection plate. At the same time, when the LED chip pops out, the reflection line of the laser sensor is blocked, and the laser sensor sends a signal to the external controller. The external controller controls the linear motor to drive the dividing box to move a certain distance to the left, and continues to pop out the next LED chip, which is convenient for automatic arrangement of LED chips.

The outer ends of the two first springs 72 located in the same material groove 71 are fixedly connected to the bottom plate 73. The inner wall of the upper end opening of the material distribution box 3 is symmetrically provided with inclined surfaces. The external controller controls the front of the material distribution box 3. The first motor 6 at the end drives the dividing plate 7 to rotate, and when the material trough 71 on the outer arc surface of the dividing plate 7 corresponds to the lower end of the upper hopper 4, the LED chip falls into the interior of the material trough 71 and contacts with the bottom plate 73, so that the outer side of the LED chip is higher than the outer arc surface of the dividing plate 7, preventing two LED chips from falling into the interior of the material trough 71 at the same time.

When the single-tooth gear 13 rotates to mesh with the gear 11, the paddle 9 is driven to rotate clockwise around the rotating shaft at the left end, so that the right end of the paddle 9 presses the second spring 10 downward. When the single-tooth gear 13 is separated from the gear 11, the second spring 10 bounces the right end of the paddle 9 upward to prevent the LED chips from bridging each other.

At the same time, the external controller controls the second motor 16 to work, driving the roller 8 on the right side to rotate, and at the same time, the roller 8 on the left side and the roller 8 on the right side are driven to rotate counterclockwise through the first pulley 81 and the belt. At the same time, the connecting belt 15 and the second pulley 14 drive the mounting shaft 12 to rotate and make the single-tooth gear 13 rotate counterclockwise.
