Description

Technical Field

[0001] The invention belongs to the field of LED feeding equipment, and in particular relates to a feeding device with a double-track design of a vibration plate. Background Art

[0002] Currently in the LED packaging industry, during LED testing and taping production, after the LED devices are poured onto a vibration plate, they spiral upward along a specific track. Sensors are installed on the track to monitor whether the front and back sides of the material and the direction of the electrodes meet the feeding test. If a single LED device is detected to have a direction that does not meet the requirements, the LED device is pushed back onto the vibration plate by blowing air, and the feeding action is repeated until the LED device meets the direction requirements. Only then is it sent to the feeding track to perform the LED device test.

[0003] LED devices that do not meet the requirements of direction are screened by the sensor and blown back into the vibration plate. The LED devices will be hit and collide with other materials when they fall into the vibration plate. They will be rubbed by the vibration plate again and continue to be fed. This may easily lead to quality risks such as dark cracks and dead lights in the LED devices, reduce the output yield, and affect the quality of the product. Therefore, it is necessary to prevent LED devices from falling directly into the vibration plate.

[0004] The LED devices are pushed back to the vibration plate by blowing air. Whether the LED devices can enter the feed track is determined by a certain probability. The pushed-back LED devices need to re-enter the guide rail. This process affects the feeding speed, and thus affects the test efficiency, reducing the production capacity of the test machine.

[0005] Currently, during the feeding process of LED devices, if the front and back sides or the electrode direction do not meet the requirements, the materials are pushed back into the vibration plate by blowing air and then re-fed. This treatment method is simple but increases the risk of material damage and prolongs the feeding time. Summary of the Invention

[0046] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0047] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Furthermore, terms such as "upper," "lower," "left," and "right" used in this disclosure are intended solely to describe the relative positions of the components of the disclosure as shown in the accompanying drawings.

[0048] Reference Figures 1 to 5 A feeding device with a double-track design of a vibration plate includes a vibration plate device 1, a first track 2, a second track 3, a direct vibration device 7, a front and back classification mechanism 4, an electrode direction adjustment mechanism 5 and a material 8 transfer device 6.

[0049] Among them, reference Figure 1 The first track 2 and the second track 3 are arranged side by side. The outlet ends of the first track 2 and the second track 3 are connected to the material 8 transfer device 6, and the inlet end of the first track 2 is connected to the outlet of the vibration disk device 1. The vibration disk device 1 sequentially transports the material 8 from the vibration disk device 1 to the outlet and enters the first track 2. The material 8 transfer device 6 is used to transfer the material 8 at the outlet ends of the first track 2 and the second track 3 to a designated location, such as an integrating sphere 9, for the next step of testing. The material 8 is an LED device.

[0050] Reference Figure 1The front and back classification mechanism 4 is arranged at one end of the first track 2 close to the vibration plate device 1, and is used to identify the front and back of the material 8 passing through the front and back classification mechanism 4 and transfer the material 8 with the back side facing up to the second track 3. After the material 8 enters the first track 2 from the vibration plate device 1, it passes through the front and back classification mechanism 4, which identifies it. If it is a material 8 with the front side facing up, the front and back classification mechanism 4 does not operate, and the material 8 continues to move toward the exit end of the first track 2. If it is a material with the back side facing up, the front and back classification mechanism 4 transfers the material 8 with the back side facing up to the second track 3. After the material 8 with the back side facing up arrives on the second track 3, it continues to move along the second track 3 toward the exit end of the second track 3.

[0051] Among them, reference Figure 1 The bottom of each of the first and second tracks 2 and 3 is provided with a direct vibration device 7, which is used to generate vibration to drive the material 8 toward the exit end of the track. The first and second tracks 2 and 3 are both hard tracks. After the direct vibration device 7 is connected to the first and second tracks 2 and 3, the first and second tracks 2 and 3 also vibrate together with the direct vibration device 7. Under this vibration, the product will move toward the exit end of the track.

[0052] Among them, reference Figures 2 to 5 The second track 3 is equipped with a flipping structure that flips the passing material 8 twice in the same direction by 90°. Specifically, when the material 8 passes through the flipping structure, it is first flipped 90°, upright, and then flipped another 90°, facing up. Subsequent operations require the material 8 to be facing up. This method ensures that all the material 8 exiting the second track 3 is facing up, eliminating the need for repeated feeding of the material 8. This helps improve feeding speed, testing efficiency, and production capacity. During this process, the material 8 will not fall and collide with other materials 8 or structures, preventing product damage and improving product yield.

[0053] Among them, reference Figure 1 The first and second tracks 2 and 3 are each equipped with an electrode orientation adjustment mechanism 5 before their respective exit ends, for adjusting the electrodes of the passing material 8 to a predetermined orientation. The electrode orientation adjustment mechanism 5 on the second track 3 is located behind the flipping structure. Subsequent use requirements for the material 8 require that, in addition to the material 8 facing up, the electrodes also face a specified direction, such as forward. Therefore, the material 8 facing up, conveyed by the first and second tracks 2 and 3, will have its electrode orientation aligned with the requirements after passing through the electrode orientation adjustment mechanism 5.

[0054] Specifically, refer to Figure 2The turning structure includes a track plane 31, a first turning slope 32, and a second turning slope 33. The first turning slope 32 and the second turning slope 33 are respectively located on either side of the track plane 31. The track plane 31 extends along the conveying direction of the material 8. For example, along the conveying direction, the first turning slope 32 is located on the left side of the material 8, and the second turning slope 33 is located on the right side of the material 8. The bottom of the material 8 falls on the track plane 31 and contacts the first turning slope 32 and the second turning slope 33.

[0055] Along the conveying direction, the second turning slope 33 is located behind the first turning slope 32, and the end of the first turning slope 32 and the front of the second turning slope 33 partially overlap in a vertical projection parallel to the conveying direction. Therefore, when the material 8 is conveyed, it first passes over the first turning slope 32 and then over the second turning slope 33.

[0056] Reference Figures 2 to 5 , the first angle α formed by the cross-sectional profile of the first flip slope 32 perpendicular to the conveying direction and the track plane 31 gradually decreases from a straight angle to an acute angle along the conveying direction; the second angle β formed by the cross-sectional profile of the second flip slope 33 perpendicular to the conveying direction and the track plane 31 gradually increases from a right angle to a straight angle along the conveying direction. Since the material 8 will first pass through the first flip slope 32 and then the second flip slope 33, and the bottom surface of the material 8 contacts the first flip slope 32 and the track plane 31, since the first angle α gradually decreases from a straight angle to an acute angle, it means that the first flip slope 32 gradually rises and becomes steeper, then the side of the material 8 that contacts the first flip slope 32 will also gradually rise, and when the first angle α is a right angle, the material 8 completes the first 90° flip, and the material 8 has reached the second flip slope 33. The material 8 continues to move, and the first angle α becomes At an acute angle, the first turning slope 32 pushes the upper end of the material 8 toward the opposite side, causing the material 8 to continue tilting. At this point, the material 8 leans against the second turning slope 33. As the material 8 continues to be conveyed, the second angle β gradually increases from a right angle to a flat angle, and the second turning slope 33 gradually flattens. The material 8 gradually lies flat against the second turning slope 33. Finally, when the second angle β becomes a flat angle, the material 8 completes a second 90° flip, and the material 8 on the second track 3 changes from facing up to facing up. During this process, the material 8 always rests against the first turning slope 32 or the second turning slope 33, without collision or damage.

[0057] In some embodiments, reference Figures 2 to 5, the overlapping parts of the first flipping slope 32 and the second flipping slope 33 are parallel to each other, and in the overlapping parts, the first angle α and the second angle β of the same cross section are complementary. Therefore, when the first angle α is 90°, the second angle β is also 90°. At this position, the material 8 just completes the first 90° flip. When the first angle α becomes an acute angle, the second angle β becomes a complementary obtuse angle, and the material 8 tilts and continues to flip for the second time.

[0058] In one embodiment, referring to Figure 2 、 Figure 3 and Figure 5 Along the conveying direction, the distance between the first turning slope 32 and the opposite track edge gradually decreases, that is, the first turning slope 32 gradually extends from the outside to the inside. When the material 8 is conveyed, it initially contacts the first turning slope 32 at the end of the bottom surface. The first turning slope 32 extends inward, and the end of the bottom surface of the material 8 is continuously raised. Eventually, the original bottom surface completely contacts the first turning slope 32, and the original side surface becomes the bottom surface, completing the first 90-degree turn. The distance between the second turning slope 33 and the opposite track edge gradually increases. In the overlapping area, the minimum width of the first turning slope 32 and the second turning slope 33 is greater than or equal to the width of the material 8 perpendicular to the conveying direction after being turned 90 degrees from the reverse side. Specifically, the second turning ramp 33 gradually extends from the inside to the outside. As the material 8 is conveyed, it initially contacts the second turning ramp 33 completely from the side. Gradually, the second turning ramp 33 extends outward, and the portion of the material 8 in contact with the second turning ramp becomes the upper end of the material 8, with the height continuously decreasing. Ultimately, the original side of the material 8 completely separates from the second turning ramp 33, and the original side of the material 8 becomes the bottom, completing a second 90-degree flip. During this entire flipping process, the material 8 flips 180 degrees and shifts horizontally by one width of the material 8. If the material 8 is initially on the track centerline 37, it will deviate from the track centerline 37 by one width of the material 8 after flipping is complete.

[0059] In another embodiment, referring to Figure 2 and Figure 4The flipping structure further includes a first guide plate 34, which is disposed opposite the first flipping ramp 32 and located on either side of the centerline 37 of the second track 3. Along the conveying direction, the first guide plate 34 extends from the outer edge of the track toward the centerline 37 of the second track 3. The distal end of the first guide plate 34 is connected to the second flipping ramp 33. The minimum width between the first guide plate 34 and the first flipping ramp 32 is greater than or equal to the width perpendicular to the conveying direction of the material 8 after it has been flipped 90° from the reverse side. During the flipping process, the first guide plate 34 guides the material 8 toward the first flipping ramp 32, preventing the material from deviating from the direction of travel after the first flip is completed. There is no lateral offset. If the material 8 is initially on the track centerline 37, it will remain on the track centerline 37 after the first flip is completed.

[0060] Similarly, refer to Figure 4 The flipping structure further includes a second guide plate 35, which is disposed opposite the second flipping ramp 33 and located on either side of the centerline 37 of the second track 3. Along the conveying direction, the second guide plate 35 extends from the inner edge of the track away from the centerline 37 of the second track 3. The front end of the second guide plate 35 is connected to the first flipping ramp 32. The minimum width between the second guide plate 35 and the second flipping ramp 33 is greater than or equal to the width perpendicular to the conveying direction of the material 8 after it is flipped 90° from the reverse side. During the flipping process, the second guide plate 35 guides the material 8 toward the first flipping ramp 32, ensuring that the material 8 remains in its original orientation after flipping, without lateral deviation. If the material 8 is on the track centerline 37 after the first flip, it will remain on the track centerline 37 after the second flip.

[0061] The following example illustrates the working principle of the flip structure:

[0062] like Figure 3 and Figure 5As shown, along the conveying direction, seven planes perpendicular to the conveying direction are set on one side, namely a, b, c, d, e, f, and g. At section a, the first angle α is a straight angle, and the first flip slope 32 is flush with the track plane 31; at section b, the first angle α is an obtuse angle, and the material 8 flips a small angle; at section c, the first angle α is an obtuse angle and is smaller than the obtuse angle at section b; at section d, the first angle α is a right angle, and the material 8 completes the first 90° flip. At this time, the second flip slope has a second angle β on this section, and the second angle β is also a right angle; at section e, the first angle α is an acute angle, and the second angle β is an obtuse angle, and the material 8 flips a small angle; at section f, there is no first angle α on this section, and the second angle β is an obtuse angle and is larger than the obtuse angle at section e; at section g, the second angle β is a straight angle, and the second flip slope 33 is flush with the track plane 31, and the material 8 completes the second 90° flip, and the front of the material 8 is now facing up.

[0063] Specifically, refer to Figure 1 The front and back side classification mechanism 4 includes a front and back sensor 41 and a push rod mechanism 42, located behind the entrance end of the first track 2. The front and back sensor 41 is used to detect the front and back sides of the passing material 8. The push rod mechanism 42 pushes the material 8 to the second track 3 when the front and back sensor 41 detects the material 8 as facing the back side. The front and back sensor 41 can distinguish the front and back sides of the material 8 based on different characteristics of the front and back sides of the material 8, such as shape, temperature, roughness, conductivity, or color. The push rod mechanism 42 includes a cylinder and a push rod. When the material 8 is detected as facing the back side upward, the cylinder drives the push rod to push the material 8 to the second track 3.

[0064] Specifically, refer to Figure 1 , the electrode direction adjustment mechanism 5 includes an electrode direction detector 51 and a rotation mechanism 52, the electrode direction detector 51 is used to detect whether the electrode direction of the passing material 8 is a predetermined direction, and the rotation mechanism 52 rotates the material 8 to the predetermined direction when the electrode direction detector 51 detects no. For example, if the required electrode direction is that the electrode faces forward, then after detecting the electrode direction, the rotation mechanism 52 rotates the material 8 with the wrong direction to the electrode facing forward. Specifically, the rotation mechanism 52 includes a lifting suction cup and a rotator, and the rotator is connected to the lifting suction cup to drive the lifting suction cup to rotate. The lifting suction cup descends, absorbs the material 8 with the wrong electrode direction and lifts it up, rotates until the electrode direction is correct, and then descends to release the material 8, completing the adjustment of the electrode direction. In one embodiment, the material 8 with the wrong electrode direction needs to be adjusted by 90°.

[0065] Among them, reference Figure 1The material 8 transfer device 6 includes a pickup portion 61 for sucking and transferring the material 8. The pickup portion 61 moves along a predetermined trajectory between the designated exit ends of the first track 2, the second track 2, and a designated release location. The pickup portion 61 can move the material 8 from the exit ends of the first track 2 and the second track 2 along the predetermined trajectory to the release location, which can be a workstation for the next process. Specifically, the pickup portion 61 includes a suction cup, which absorbs and releases the material.

[0067] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
