Description

Technical Field

[0001] The present invention relates to the application field of LED lamps, and in particular to a lamp mixing device and a lamp mixing method. Background Art

[0002] LED lamps (light emitting diodes) have the advantages of small size, energy saving, environmental protection, high reliability, and long life. Their application range is becoming more and more extensive, such as LED electronic display screens, traffic signs, conference rooms, car lights, landscape lighting, etc. LED display screens are composed of LED lamps one by one. In order to make LED lamps with different brightness and wavelength parameters evenly distributed to achieve the best display effect, these slightly different LED lamps need to be mixed evenly to reduce the low brightness or high brightness concentration to produce bright spots or dark spots or large-area screen effects. It is necessary to introduce a mixed lamp process to evenly disperse these LED lamps to produce a consistent display effect.

[0003] At present, the commonly used method of mixing lamps is to rely on manual operation or small batch introduction of semi-automatic vibration plate operation, that is, the operator lays down anti-static leather, wears anti-static ring, pours the whole package of LED into the plastic frame or device, and then mixes the LEDs in different plastic frames by throwing and exchanging them multiple times. This manual mixing method is difficult to maintain consistent strength, quantity and frequency of manual throwing. During the mixing process, the outdoor lamp feet are also easy to pierce the hands and deform the lamp feet. The lamp cup is easily scratched and the mixing effect is poor. Mixing lamps on a vibration plate will cause the lamps to be worn black and polluted. It is not easy to mix evenly, and the operation process consumes manpower and is inefficient.

[0023] Embodiments of the present invention Figure 1 and Figure 2As shown in the figure, a mixed lamp device includes a left bracket 1 and a right bracket 2. The left and right brackets can be brackets of the same structure or brackets of different structures. The selection is made according to different needs and different production conditions. In order to facilitate production, the left and right brackets are selected to be brackets of the same structure. At the same time, in order to facilitate the movement of the mixed lamp device, casters 10 are installed at the bottom of the left bracket 1 and the right bracket 2. Different numbers of casters 10 are installed according to the structure of different brackets. The casters 20 are universal wheels to facilitate their movement to meet the use requirements in different positions. Feeding mechanisms 3 are provided on the left bracket 1 and the right bracket 2. The feeding mechanism The structure 3 is provided with a feeding channel 30 with a through hole in an inverted trapezoidal structure from top to bottom. At this time, the feeding mechanism 3 can select a conventional feeding mechanism and set the feeding channel 30 thereon, and the feeding channel 30 is a through hole in an inverted trapezoidal structure, so that the LED lights will pass through the upper and lower ends of the feeding channel 30 in sequence and flow out of the feeding channel 30. The upper end of the feeding channel 30 is the feeding port 300 and the lower end is the discharging port 301. Similarly, for the convenience of production, the feeding mechanisms 3 on the left bracket 1 and the right bracket 2 are also feeding mechanisms of the same structure; a left conveyor belt with a material trough 40 is arranged at intervals between the left bracket 1 and the right bracket 2. 4 and the right conveyor belt 5, which means that the left and right conveyor belts are not in contact with each other, and will not affect each other's movement transmission. The material trough 40 thereon is used to carry LED lights to facilitate their transportation. The left conveyor belt 4 is arranged corresponding to the rear end of the left bracket 1 and the right bracket 2, and the right conveyor belt 5 is arranged corresponding to the front end of the left bracket 1 and the right bracket 2, which is convenient for loading before mixing and also convenient for collecting after mixing. The material troughs 40 of the left conveyor belt 4 are connected end to end in sequence and arranged along the left conveyor belt 4 for one week, and the material troughs 40 of the right conveyor belt 5 are connected end to end in sequence and arranged along the right conveyor belt 5 for one week, that is, the material troughs 40 are distributed all over the conveyor belt, and the conveyor belt It is an annular structure, and the material trough 40 is arranged on the outer wall of the conveyor belt. With the movement of the conveyor belt, part of the material trough 40 is in an upward state, and part of it is in a downward state, which can not only transmit but also make the LED lights dropped from the discharge port 301 of the feeding mechanism 3 fall into the material trough 40. The left end of the left conveyor belt 4 is directly below the discharge port 301 of the feeding mechanism 3 on the left bracket 1, and the right end is above the feeding port 300 of the feeding mechanism 3 on the right bracket 2. The left end of the right conveyor belt 5 is above the feeding port 300 of the feeding mechanism 3 on the left bracket 1, and the right end is directly below the discharge port 301 of the feeding mechanism 3 on the right bracket 2.The left bracket 1 is also provided with a left driving motor 6 for driving the left conveyor belt 4 to move to the right, and the right bracket 6 is also provided with a right driving motor 7 for driving the right conveyor belt 5 to move to the left. In order to facilitate the control of the motor and the synchronous operation of the entire mixing device, the left driving motor 6 and the right driving motor 7 are electrically connected to a controller electrically connected to a power supply at the same time. The controller is connected to the power supply to control the start or shut down of the left and right driving motors, adjust the speed of the motors and thus adjust the transmission speed of the left and right conveyor belts, thereby controlling the mixing speed of the mixer. The left and right drive motors can be controlled to run synchronously through the controller to reduce the number of control steps. In this way, the left drive motor 6 drives the left conveyor belt 4 to move to the left. The left end of the left conveyor belt 4 is directly below the discharge port 301 of the feeding mechanism 3 on the left bracket 1. First, the LED lamps that need to be mixed are placed in the material trough 40 at the left end of the right conveyor belt 5 above the feeding mechanism 3 on the left bracket 1. Then, the right conveyor belt 5 is driven to the left by the right drive motor 7, and the material trough 40 at its left end is tilted downward, and the LED lamps therein are passed through the material trough 40. The feed port 300 of the feed mechanism 3 enters the feed channel 30 and undergoes the first mixing. Then, it freely falls by its own gravity to the left end of the left conveyor belt 4 at the discharge port 301 and undergoes the second mixing. The LED lamps that fall into the upper trough 40 of the left conveyor belt 4 are transported to the upper part of the feed mechanism 3 on the right bracket 2 as the left conveyor belt 4 moves to the right. When the LED lamps pass the right end of the left conveyor belt 4, the trough 40 tilts downward, and the LED lamps therein freely fall by their own gravity through the feed port of the feed mechanism 3 of the right bracket 2. 300 enters the feeding channel 30, undergoing the third mixing, and then freely falls through the discharge port 301 of the feeding channel 30 into the right end of the right conveyor belt 5 directly below it, undergoing the fourth mixing, and then the LED lamp is transported to the upper part of the feeding mechanism 3 on the left bracket 1 as the right conveyor belt 5 moves to the left, forming a cycle, and multiple cycles can be performed according to different needs. Of course, the LED lamps that need to be mixed can also be placed in the material trough 40 at the right end of the left conveyor belt 4 first to perform the corresponding cycle;Each of the feeding mechanisms 3 is provided with an adjusting member 8 for controlling the size of the diameter of its discharge port 301. The diameter of the discharge port 301 can be controlled by the adjusting member 8, thereby controlling the size of the discharge, so that the size of the LED lamps discharged through the discharge port 301 is consistent, keeping the lamps uniform. In this way, when mixing the lamps, pour the unpacked LED lamps into the material trough 40 of a conveyor belt, and the LED lamps will be slowly transported to the top of the corresponding feeding mechanism 3 with the conveyor belt. The material trough 40 tilts downward with the movement of the conveyor belt, and the LED lamp tubes will be scattered freely and fall into the feeding channel 30. By controlling the size of the discharge port 301 of the feeding channel 30, the discharge size can be controlled. The LED is discharged to another conveyor belt, and after mixing the lamps again, it is slowly transmitted to another feeding mechanism 3 through the conveyor belt. The lamp tubes will be scattered freely and fall into the feeding channel 30 for free mixing again. The two conveyor belts form an 8-type circular transmission, and each cycle will experience 4 mixing of lamps. The mixing process depends entirely on the free fall of the lamps themselves. The position is freely exchanged, and the cycle operation has little damage to the lamp tubes, fast efficiency, no manual operation, no harm to the body, and more uniform mixing. ;

[0024] Further improvements, such as Figure 1 and Figure 2 As shown in the figure, the feeding mechanism 3 is a funnel with an inverted trapezoidal structure, and a feeding channel 30 leading to the through hole of the trapezoidal structure is naturally formed inside, which facilitates production. After the LED lamp falls into the feeding channel 30, the internal inclined surface will automatically slide down along the inclined surface to the discharge port 301.

[0025] Further improvements, such as Figure 1 As shown in the figure, the left conveyor belt 4 and the right conveyor belt 5 are both provided with an adjusting support rod 9 for adjusting the height thereof. The adjusting support rod 9 is used to support the conveyor belt on the one hand, and can be used to adjust the height of the conveyor belt on the other hand. When the height is higher, due to the different falling speeds of LED lamps of different weights, the lamps initially gathered together can be easily distinguished and separated, and then mixed again during the fall to obtain evenly mixed lamps. When the height is too low, due to the limited falling distance, the lamps of different weights cannot be well separated, so that the lamps originally gathered together are still gathered together, resulting in unevenness in the final mixed lamps.

[0026] Further improvements, such as Figure 1 and Figure 2As shown in the figure, the feed channel 30 is a non-isosceles inverted trapezoidal structure. Non-isosceles means that one side of the waist of the inverted trapezoid is longer than the other side. The right end of the left conveyor belt 4 and the left end of the right conveyor belt 5 both correspond to the longer waist setting on the feed channel 30, that is, the feeding corresponds to the long side. The distance of the LED lamp from the feed port 300 to the discharge port 301 on this side is longer, so the LED lamps gathered together can be better separated, and then fall into the material trough 40 of the conveyor belt through the discharge port 301, which makes the mixing more uniform and can also prevent the LED lamp from splashing out from the feed port 300 when falling into the feed port 300.

[0027] Further improvements, such as Figure 1 As shown in, the adjusting member 8 includes a limit plate and an adjusting handle connected to the limit plate for adjusting the limit plate. The adjusting handle is arranged on the outer wall of the feeding mechanism for easy operation and adjustment. The limit plate is used to limit the size of the discharge port. It crosses the side wall of the feeding mechanism and slides radially along the side wall of the feeding mechanism by adjusting the adjusting handle on the side wall. The limit plate is arranged on the outer wall of the feeding channel at a position adjacent to the discharge port and passes through the side wall of the feeding channel and can be movably extended into the feeding channel, so that the limit plate can be easily extended into the feeding channel to reduce the diameter of the discharge port, and the diameter of the discharge port can be expanded by pulling out the limit plate. At this time, a through hole can be arranged on the side wall of the feeding mechanism, and then the limit plate is slidably arranged in the through hole, and an manually adjustable adjusting handle is arranged at the tail of the limit plate to achieve this. It can also be achieved by adjusting the mechanical adjustment handle of the limit plate in and out of the feeding channel through some mechanical transmission. Different adjusting members can be selected according to different production needs.

[0028] A lamp mixing method, using the lamp mixing device as described in any of the above items to mix lamps, the steps are as follows:

[0029] S1, pour the LED lamps to be mixed into the trough at the right end of the left conveyor belt or the trough at the left end of the right conveyor belt. Since the left and right conveyor belts form a cyclic transmission process, the selection is based on different production needs and convenience of use;

[0030] S2, start the left drive motor and the right drive motor to drive the left conveyor belt and the right conveyor belt to move, and adjust the conveyor belt movement speed and the number of mixing cycles. One cycle will mix the lights four times. In order to mix more evenly, the number of cycles is adjusted to achieve more mixing;

[0031] S3, the cycle ends, and the LED lights in the left conveyor belt and the right conveyor belt trough are collected, so that a mixed LED light is formed, which is used for display screens or other devices to obtain the best display effect.

[0032] It should be understood that those skilled in the art may make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
