Description

Technical Field

[0001] The present invention relates to the technical field of lamp production, and in particular to a lamp bead assembly device and a use method thereof. Background Art

[0002] Lamp beads, also known as light-emitting diodes, or LEDs in English, are semiconductor devices that can convert electrical energy into visible light. They are commonly used light-emitting devices. Light-emitting diodes can efficiently convert electrical energy into light energy and have a wide range of uses in modern society. With the development of technology, SMD light-emitting diodes such as 2835 lamp beads have emerged. These diodes have the advantages of smaller size, longer life, lower energy consumption, and timely response, and have been widely used in lamps, lighting, and other fields. When assembling lamp beads, manual welding is mostly used. The traditional solder wire and electric soldering iron are relatively large for lamp beads measured in millimeters. Therefore, solder paste and hot air blowers are used when welding rectangular lamp beads.

[0003] During the operation, solder paste is applied to the electrodes at the installation points of the lamp beads with a syringe, and then the lamp beads are clamped with tweezers and placed at the points, and heated with a hot air gun to complete the welding. Although the solder paste has the characteristic of automatically finding points after heating, the wind force will affect the accurate installation of the lamp beads during the heating process with the hot air gun. In addition, the lamp beads are small in size and difficult to clamp manually, so the welding process is cumbersome and difficult.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1-9 , the embodiments of the present invention provide a lamp bead assembly device, including: a processing table 1, a substrate 2, a feeding pipe 3, a first driving assembly 4, a second driving assembly 5, two clamping assemblies 6, a transmission assembly 7, an air blowing pipe 8 and a material transporting plate 9.

[0039] Among them, as Figure 1 shown, the processing table 1 is mainly used for installation and support. Specifically, a moving groove 12 is opened along the length direction of the processing table 1, the top of the moving groove 12 is communicated with the outside, and one side of the processing table 1 is fixedly connected with an extension plate 13, and the extension plate 13 also mainly plays a role in installation and support. A support frame 11 is arranged on the extension plate 13, and the support frame 11 includes: a fixed seat 111 and two support plates 112. The fixed seat 111 is fixedly connected to the extension plate 13, the two support plates 112 are parallel to each other, and one ends of the two support plates 112 are fixedly connected to the fixed seat 111, and the other ends of the two support plates 112 extend to the side away from the extension plate 13.

[0040] As Figure 1 , Figure 2 and Fig. 9As shown in the figure, the blanking pipe 3 is located between two support plates 112. The blanking pipe 3 is mainly used for the directional transportation of lamp beads. The blanking pipe 3 is vertically arranged. An inlet 31 is provided at the top of the blanking pipe 3, and an outlet 32 is provided at the bottom of the blanking pipe 3. The cross-sectional dimension of the blanking pipe 3 in the length direction is the same as the cross-sectional dimension of the lamp bead in the length direction. It should be noted that the lamp bead in this application has a cuboid structure, and the cross-sectional dimension of the blanking pipe 3 in the length direction is the same as the cross-sectional dimension of the lamp bead in the length direction. That is to say, the lamp bead can only enter the inside of the blanking pipe 3 from the inlet 31 along the length direction, and then fall onto the lamp bead installation point 21 from the outlet 32. This can orient and limit the installation of the lamp bead, thereby facilitating the installation of the lamp bead and improving the accuracy of lamp bead installation.

[0041] The first driving assembly 4 is arranged on the support frame 11 and is connected to the blanking pipe 3 to drive the blanking pipe 3 to move in the vertical direction. Specifically, the first driving assembly 4 includes a U-shaped frame 41 with an opening facing the support frame 11. The bottom parts of the two side walls of the U-shaped frame 41 are respectively connected to the two support plates 112. A cylinder 42 is fixedly connected to the top wall of the support frame 11, and the telescopic end of the cylinder 42 is fixedly connected to the outer wall of the blanking pipe 3. During use, before installing the lamp bead, first start the cylinder 42 to move the outlet 32 on the blanking pipe 3 downward to a position where it fits the corresponding lamp bead installation point 21, and then put the lamp bead into the blanking pipe 3 from the inlet 31. After the lamp bead enters the blanking pipe 3, it will fall from the outlet 32 to the position of the lamp bead installation point 21. Since the outlet 32 fits the lamp bead installation point 21, the lamp bead will not completely separate from the blanking pipe 3. At this time, start the cylinder 42, and the cylinder 42 drives the blanking pipe 3 to move upward, and the lamp bead will gradually separate from the blanking pipe 3, and thus will fall onto the lamp bead installation point 21 with solder paste.

[0042] As Fig. 9 shown, as an optional embodiment, the structure of the outlet 32 is an arc structure, and the length of the side wall of the outlet 32 away from the center of the circle is less than the length of the side wall of the outlet 32 close to the center of the circle. It should be noted that the center of the circle is the center of the circle corresponding to the arc-shaped outlet 32. That is to say, the lamp bead is in an inclined state after being transported out of the outlet 32. Since the lamp bead contacts the solder paste with the plane where the length and width are located, this can reduce the contact area between the plane where the width and thickness of the lamp bead are located and the solder paste, thereby reducing the subsequent adjustment of the position of the lamp bead. Moreover, the length of the side wall of the outlet 32 away from the center of the circle is less than the length of the side wall of the outlet 32 close to the center of the circle. In this way, during the falling process of the lamp bead, one end of the lamp bead will first contact the solder paste. During the upward movement of the blanking pipe 3, the other end of the lamp bead will contact the solder paste under the action of gravity because it is close to the side wall of the outlet 32 away from the center of the circle, and thus the contact surface between the lamp bead and the solder paste can be accurately adjusted, and the installation is more accurate.

[0043] like Figure 1 As shown, the substrate 2 is mainly used to install lamp beads, and two rows of lamp bead installation points 21 are provided on the substrate 2. Electrodes are provided on the lamp bead installation points 21 for electrical connection with the lamp beads. The substrate 2 is movably arranged on the processing table 1. Specifically, the substrate 2 can be moved along the length direction of the processing table 1, and the substrate 2 can be rotated, so as to facilitate the adjustment of the position of the lamp bead installation points 21 on the substrate 2, thereby facilitating the installation of the lamp beads.

[0044] like Figure 1 and Figure 4 As shown, the second driving assembly 5 is arranged on the processing table 1, and is used to drive the substrate 2 to move and rotate, so as to make the position of the lamp bead installation point 21 on the substrate 2 correspond to the position of the discharge port 32 of the feeding tube 3. Specifically, the second driving assembly 5 includes: a first motor 51, a second motor 52, a nut seat 53 and a screw rod 54, the screw rod 54 is rotatably connected in the moving groove 12, and the axial direction of the screw rod 54 is the same as the length direction of the limiting groove 551, one end of the screw rod 54 passes through the processing table 1 and is fixedly connected to the first motor 51, the screw rod 54 is threadedly connected with the nut seat 53, the second motor 52 is fixedly connected to the nut seat 53, the output shaft of the second motor 52 is in the vertical direction, and the output shaft of the motor is fixedly connected with a limiting plate 55 for supporting the substrate 2. When in use, the substrate 2 is placed on the limit plate 55, and the first motor 51 is started. The first motor 51 will drive the screw rod 54 to rotate, and the rotation of the screw rod 54 will drive the nut seat 53 to move along the axis direction of the screw rod 54. The movement of the nut seat 53 will drive the second motor 52 to move. Since the output end of the second motor 52 is fixedly connected to the limit plate 55, the movement of the nut seat 53 will drive the substrate 2 to move in the moving groove 12 through the second motor 52 and the limit plate 55, and then the position of the lamp bead installation point 21 along the length direction of the moving groove 12 can be adjusted, so that the lamp bead installation points 21 can be installed at multiple lamp bead installation points 21. When a row of lamp bead installation points 21 is installed, the second motor 52 is started, and the second motor 52 drives the limit plate 55 to rotate. The rotation of the limit plate 55 drives the substrate 2 to rotate, so that the lamp bead installation points 21 of another row can be rotated to the side that cooperates with the discharge tube 3, and then the first motor 51 is started to drive the lamp bead installation points 21 on the other row to cooperate with the discharge tube 3 in sequence.

[0045] like Figure 1 and Figure 2As shown, as an optional embodiment, a limiting groove 551 is provided on the limiting plate 55, the depth of the limiting groove 551 is less than the thickness of the substrate 2, and the substrate 2 is placed in the limiting groove 551. The limiting groove 551 mainly plays a limiting role, and placing the substrate 2 in the limiting groove 551 can make the movement and rotation of the substrate 2 more stable. The depth of the limiting groove 551 is less than the thickness of the substrate 2, so that it is easy to take the substrate 2 out of the limiting groove 551.

[0046] like Figure 1 , Figure 5 and Figure 8 As shown, in addition, two clamping assemblies 6 are connected to the support frame 11, and the two clamping assemblies 6 are arranged opposite to each other and are respectively located on both sides of the feed tube 3, so as to limit the position of the lamp beads located at the lamp bead installation point 21 when the feed tube 3 moves upward, and limit and release the lamp beads located at the lamp bead installation point 21 when the feed tube 3 moves downward. Specifically, the clamping assembly 6 includes a fixing plate 61, the fixing plate 61 is connected to the support plate 112, and a guide rod 62 is fixedly connected to the fixing plate 61, and there is an angle between the guide rod 62 and the horizontal plane, and the end of the guide rod 62 away from the fixing plate 61 is slidably connected to a clamping rod 63 for selectively clamping the lamp beads. In other words, the clamping rod 63 can slide on the guide rod 62. When the clamping rods 63 on both sides slide obliquely downward along the corresponding guide rods 62, the two clamping rods 63 will press and limit the lamp beads located at the lamp bead installation point 21, so as to facilitate the subsequent hot blowing of the solder paste to keep the lamp beads stable. When the clamping rods 63 on both sides slide obliquely upward along the corresponding guide rods 62, the two clamping rods 63 will release the limit of the lamp beads located at the lamp bead installation points 21, so as to facilitate the subsequent adjustment of the position of the substrate 2. It should be noted that during the sliding process of the clamping rods 63, the guide rods 62 will not penetrate the clamping rods 63.

[0047] like Figure 4-Figure 8 As shown, in addition, one end of the transmission assembly 7 is connected to the feeding tube 3, and the other end is connected to the clamping assembly 6, so as to transmit the movement of the feeding tube 3 to the two clamping assemblies 6. Specifically, the transmission assembly 7 includes: a first rack plate 71, a second rack plate 72, a first transmission shaft 73, a second transmission shaft 74, a third transmission shaft 75, a fourth transmission shaft 76, a first gear 77 and a second gear 78. Among them, both ends of the first transmission shaft 73, the second transmission shaft 74, the third transmission shaft 75 and the fourth transmission shaft 76 are respectively rotatably connected to the two support plates 112, and the axes of the first transmission shaft 73, the second transmission shaft 74, the third transmission shaft 75 and the fourth transmission shaft 76 are parallel to each other. The first transmission shaft 73 and the second transmission shaft 74 are both located on one side of the feeding tube 3, specifically the side close to the extension plate 13, and the third transmission shaft 75 and the fourth transmission shaft 76 are both located on the other side of the feeding tube 3, specifically the side away from the extension plate 13.

[0048] The first gear 77 is fixedly connected to the first transmission shaft 73, and the first rack plate 71 is fixedly connected to the discharge pipe 3, and the first rack plate 71 is adapted to the first gear 77, and a first pulley assembly 79 is transmission-connected between the first transmission shaft 73 and the second transmission shaft 74, and the first pulley assembly 79 is prior art, and a first connecting rod 701 is fixedly connected to the second transmission shaft 74, and a free end of the first connecting rod 701 is rotationally connected to a second connecting rod 702, and a free end of the second connecting rod 702 is rotationally connected to a corresponding clamping rod 63. In this way, when the lower feeding tube 3 drives the first rack plate 71 to rise, the lamp beads will be separated from the lower feeding tube 3 and completely fall onto the solder paste, the first rack plate 71 will drive the first gear 77 to rotate, the rotation of the first gear 77 will drive the first transmission shaft 73 to rotate, the rotation of the first transmission shaft 73 will drive the second transmission shaft 74 to rotate through the first pulley assembly 79, the rotation of the second transmission shaft 74 will drive the first connecting rod 701 to rotate, the rotation of the first connecting rod 701 will drive the second connecting rod 702 to rotate, and the rotation of the second connecting rod 702 will drive the corresponding clamping rod 63 to move obliquely downward on the guide rod 62 to achieve the pressing of the lamp beads. Conversely, when the lower feeding tube 3 drives the first rack plate 71 to descend, the second connecting rod 702 will drive the corresponding clamping rod 63 to move obliquely upward on the guide rod 62 to release the pressing of the lamp beads.

[0049] The second gear 78 is fixedly connected to the third transmission shaft 75, and the second rack plate 72 is fixedly connected to the discharge tube 3, and the second rack plate 72 is adapted to the second gear 78, and a second pulley assembly 703 is transmission-connected between the third transmission shaft 75 and the fourth transmission shaft 76, and the second pulley assembly is prior art, and a third connecting rod 704 is fixedly connected to the fourth transmission shaft 76, and the free end of the third connecting rod 704 is rotationally connected to the fourth connecting rod 705, and the free end of the fourth connecting rod 705 is rotationally connected to the corresponding clamping rod 63. In this way, when the lower feeding tube 3 drives the second rack plate 72 to rise, the lamp beads will be separated from the lower feeding tube 3 and completely fall onto the solder paste, and the second rack plate 72 will drive the second gear 78 to rotate, and the rotation of the second gear 78 will drive the third transmission shaft 75 to rotate, and the rotation of the third transmission shaft 75 will drive the fourth transmission shaft 76 to rotate through the second pulley assembly 703, and the rotation of the fourth transmission shaft 76 will drive the third connecting rod 704 to rotate, and the rotation of the third connecting rod 704 will drive the fourth connecting rod 705 to rotate, and the rotation of the fourth connecting rod 705 will drive the corresponding clamping rod 63 to move obliquely downward on the guide rod 62 to achieve the pressing of the lamp beads. Conversely, when the lower feeding tube 3 drives the second rack plate 72 to descend, the fourth connecting rod 705 will drive the corresponding clamping rod 63 to move obliquely upward on the guide rod 62 to release the pressing of the lamp beads. In this way, by pressing the lamp bead on two opposite sides of the lamp bead through the two clamping rods 63, the position of the lamp bead can be kept stable when the solder paste is hot-blown.

[0050] like Figure 7 As shown, further, one end of the air blowing pipe 8 is connected to the support frame 11, and the other end of the air blowing pipe 8 corresponds to the position at the lamp bead mounting point 21 to heat the solder paste coated at the lamp bead mounting point 21. Specifically, the air blowing pipe 8 includes a main pipe 81 and a air supply pipe 82. The main pipe 81 is communicated with the air supply pipe 82, and the main pipe 81 is fixedly connected to the support plate 112. The main pipe 81 is in the vertical direction, and the air supply pipe 82 is in a U-shaped structure. The air supply pipe 82 is provided with two air outlets, and the two air outlets are located on both sides of the blanking pipe 3. It should be noted that in order to avoid interference between the air outlets and the two clamping rods 63, the two air outlets and the two clamping rods 63 are staggeredly distributed, and the two air outlets are oppositely arranged. When in use, hot air is introduced into the main pipe 81. After the hot air enters the main pipe 81, it will flow into the air supply pipe 82, and then flow out from the two side air outlets to heat the solder paste on the lamp bead mounting point 21, so that the lamp beads can be firmly mounted on the substrate 2.

[0051] As Figure 1-Figure 3 shown, in addition, the material transporting plate 9 is horizontally arranged. The material transporting plate 9 is provided with a transportation channel 91 having the same width as the width of the lamp bead. A plurality of lamp beads are located in the transportation channel 91. The transportation channel 91 is flush with the feeding port 31 at the lowest position. One side of the material transporting plate 9 is fixedly connected with a connecting frame 92, and the connecting frame 92 is fixedly connected to the support frame 11. The material transporting plate 9 is horizontally arranged, so that a plurality of lamp beads can be placed on the material transporting plate 9 in advance, which is convenient for subsequently transporting the lamp beads to the corresponding lamp bead mounting points 21 through the blanking pipe 3.
