DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0041] As shown in Figures 1 to 12 , the lighting lamp bead welding equipment is used for welding a lamp bead substrate. The lighting lamp bead welding equipment comprises a main frame 10, two clamping mechanisms 20, a deflection mechanism 30 and a welding mechanism 40. The clamping mechanisms 20 are installed on both sides of the main frame 10, and the main frame 10 comprises a bottom frame 11 and a bracket 12. As shown in Figures 4 to 5 , the deflection mechanism 30 comprises a driving motor 31, a commutator 32 and a bearing disc 33. The driving motor 31 is installed at the lower end of the bottom frame 11, the commutator 32 is installed at the upper end of the bottom frame 11, and the driving motor 31 is in transmission connection with the commutator 32 through a belt pulley. One end of the commutator 32 is connected with the bearing disc 33, and the lamp bead substrate 50 is clamped on the bearing disc 33. The commutator 32 is provided with a rotation shaft 35, one end of the rotation shaft 35 is connected with the driving motor 31 through a belt pulley, the other end of the rotation shaft 35 is fixedly connected with a correcting piece 36, and the correcting piece 36 is installed with a first electromagnetic sensor 37. A set of assembly frames 38 are further installed on the bottom frame 11, the assembly frames 38 are installed with a second electromagnetic sensor 310, and in one state, the first electromagnetic sensor 37 and the second electromagnetic sensor 310 are on the same axial line.

[0042] As shown in Figures 2 to 3As shown, the clamping mechanism 20 is used to limit the axial movement of the lamp bead substrate 50, wherein the clamping mechanism 20 comprises a connecting frame 21, a frame plate 22 and a sliding sleeve 23. The connecting frame 21 is installed on both sides of the base frame 11, and the frame plate 22 is installed on the connecting frame 21. The sliding sleeve 23 is fixedly connected with the frame plate 22, and the sliding sleeve 22 has a sliding shaft 24 fixedly connected with a connecting shaft 25, and the sliding shaft 25 is movably connected with the sliding sleeve 22 and is used to adjust the axial stroke thereof. The support 12 is connected with a sliding frame 26 above, and the sliding frame 26 is connected with a first air cylinder 27, and the output shaft of the first air cylinder 27 is connected with a clamping head 28 which is slidably connected with the connecting shaft 25, wherein the clamping head 28 is located above the lamp bead substrate 50 in a state.

[0043] When welding the lamp bead substrate 50, the connecting shaft 25 and the components installed thereon are first adjusted to be located above the lamp bead substrate 50 through the sliding shaft 24, and then the first air cylinder 27 is controlled to be elongated to press the clamping head 28 above the lamp bead substrate 50. At this time, the lamp bead substrate 50 can still rotate with the carrier disc 33.

[0044] As shown in Figure 8 , Figure 9 , Figure 11 and Figure 12 , the welding mechanism 40 comprises a welding structure 41 and a moving structure 42. The welding structure 40 comprises a connecting block 412, a first connecting piece 413 and a second connecting piece 416. The connecting block 412 is fixedly installed on the output shaft of a second air cylinder 411, and the second air cylinder 411 is installed above the support 12. The first connecting piece 413 is slidably installed with the connecting block 412 through a return spring 414, and a top block 415 is further installed on the first connecting piece 413, and a welding head 418 and a scraper 419 are installed on the second connecting piece 416. The moving structure 42 comprises an arc-shaped shell 422, a limiting piece 423 and a third air cylinder 424. A frame plate frame 421 is fixedly installed on the base frame 11, and the arc-shaped shell 422 is fixedly installed with the frame plate frame 421. The output shaft of the third air cylinder 424 is connected with the limiting piece 423, and the top block 415 is in contact with the limiting piece 423. Among them, the return spring 414 is in a stretched state.

[0045] As shown in Figures 11 to 12 , the limiting piece 423 is composed of a first limiting plate 423'1, a second limiting plate 423'2, a third limiting plate 423'3 and a fourth limiting plate 423'4, and in the initial state, the top block 415 is in contact with the first limiting plate 423'1. A clamping groove is provided on each of the second limiting plate 423'2, the third limiting plate 423'3 and the fourth limiting plate 423'4, and the length of the clamping groove is deepened in turn, that is, the length of the clamping groove on the fourth limiting plate 423'4 > the length of the clamping groove on the third limiting plate 423'3 > the length of the clamping groove on the second limiting plate 423'2.

[0046] AsFigure 9 As shown, the top block 415 includes a vertical part 415'1 and an arc head part 415'2. The vertical part 415'1 is in contact with the first limiting plate 423'1, and is located in the clamping groove of the second, third or fourth limiting plate when the limiting member 423 moves upward. When the limiting member 423 moves downward, the clamping groove of the second, third or fourth limiting plate pushes the arc head part 415'2 on the top block 415 to stretch the return spring 414. The upper end of the arc-shaped shell 422 is provided with a third electromagnetic sensor 425, and the fourth limiting plate 423'4 is provided with a fourth electromagnetic sensor 426. When the third electromagnetic sensor 425 contacts the fourth electromagnetic sensor 426, the third cylinder 424 controls the limiting member 423 to move downward.

[0047] In the initial state, the first electromagnetic sensor 37 is on the same axis line as the second electromagnetic sensor 310 (as shown in FIG. 6A). Figure 5 When the correction member rotates clockwise or counterclockwise by one circle, and the first electromagnetic sensor 37 is again on the same axis line as the second electromagnetic sensor 310, the output shaft of the third cylinder 424 drives the limiting member 423 to move upward by one unit distance (the second limiting plate 423' moves to the position of the first limiting plate 423'1). Under the elastic force of the return spring 414, the top block 415 is pushed into the clamping groove position on the second limiting plate 423'2. By analogy, when the third electromagnetic sensor 425 contacts the fourth electromagnetic sensor 426, the third cylinder 424 drives the limiting member 423 to return to the initial position.

[0048] In this embodiment, after the lamp bead substrate 50 is clamped, the welding head 418 is adjusted to a suitable position above the lamp bead substrate 50 by the second cylinder 411. When the second cylinder 411 adjusts the position, the third cylinder 424 is also adjusted synchronously to ensure that the top block 415 is always in contact with the limiting member 423 during the adjustment process. Figures 6 to 7 As shown, the lamp bead substrate 50 is composed of a PVB plate 51 and a plurality of filament substrates 52, and the filament substrates 52 are located at different layers. When the lamp bead substrate 50 is welded, tin paste is used to weld the filament substrates 52 at the same layer two by two (as shown in FIG. 8A). Figure 7The welding mechanism 40 welds the outermost layer of the filament substrate 52 first, and then welds the inner layer of the filament substrate 52 in sequence. When welding the outermost layer of the filament substrate 52, the welding head 418 welds one group of the filament substrate 52, and then the driving motor 31 drives the carrier disc 33 and the lamp bead substrate 50 mounted thereon to deflect by a certain angle through the commutator 32. Then the welding head 418 welds another group of the filament substrate 52, until the outermost layer of the filament substrate 52 is completely welded. That is, the carrier disc 33 rotates one circle, and since the carrier disc 33 is connected with the commutator 32, the rotation of the carrier disc 33 one circle is equivalent to the rotation of the correction member 36 on the rotating shaft 35 one circle. When the correction member 36 rotates one circle, the first electromagnetic sensor 37 is again coaxial with the second electromagnetic sensor 310. The third cylinder 424 drives the limiting member 423 to move upward by a unit distance. Under the elastic force of the reset spring 414, the top block 415 is pushed into the clamping groove position on the second limiting plate 423'2. At this time, the welding head 418 is located at the second layer, and the above steps are repeated to complete the welding of the filament substrate 52 on the second layer. After the welding of the second layer is completed, the correction member 36 rotates one circle again to control the third cylinder 424 to drive the limiting member 423 to move upward by a unit distance. The top block 415 is pushed into the clamping groove position on the third limiting plate 423'3 to weld the filament substrate 52 on the third layer. In this way, the filament substrate 52 on the lamp bead substrate 50 is completely welded. The number of limiting plates on the limiting member 423 can be adjusted according to the number of layers of the filament substrate 52 to be welded.

[0049] When the third electromagnetic sensor 425 contacts the fourth electromagnetic sensor 426, it means that the welding of the lamp bead substrate 50 is completed, and the top block 415 needs to be pushed back to the initial position. As shown in Figure 13 At this time, the top block 415 is located in the clamping groove of the fourth limiting plate 423'4, and the output shaft of the third cylinder 424 is retracted to drive the limiting member 423 to move downward. When the limiting member 423 moves downward, the end surface a on the third limiting plate 423'3 pushes the arc head 415'2 to move, and the reset spring is stretched until the vertical part 415'1 is located in the clamping groove of the third limiting plate 423'3. Continue to move downward, the end surface b on the second limiting plate 423'2 pushes the arc head 415'2 to move until the vertical part 415'1 is located in the clamping groove of the second limiting plate 423'2, and in this way, the top block 415 returns to the initial position and is attached to the first limiting plate 423'1.

[0050] In this embodiment, further, a plurality of supporting members 34 are mounted below the carrier disc 33, and the supporting member 34 is composed of a fixed rod and a roller, and the supporting member 34 is used to increase the bearing capacity of the carrier disc 33. The correction member 36 is a regular n-polygon, and n is an even number, as shown in Figure 5The correction member 36 is a regular octagon. The first electromagnetic sensor 37 is mounted on one side of the correction member 36. Two metal springs 39 are mounted on two mutually parallel sides of the correction member 36 and are attached to the assembling frame 38. The metal springs 39 are used to correct the deflection angle of the carrier disc 33 and prevent the deflection angle of the carrier disc 33 from being less than a predetermined value.

[0051] When the filament substrate is welded, two points on the filament substrate are welded respectively and then connected. This welding method has firm welding points but poor connection line effect and is prone to failure or short circuit. Therefore, the welding structure is further improved.

[0052] In the embodiment, as shown in Figure 9 The first connecting member 413 is provided with an adjusting member 417 which connects the second connecting member 416 with the first connecting member 413. The adjusting member 417 controls the movement of the second connecting member 416 along the first connecting member 413. Figure 9 As shown in

[0053] As shown in Figure 10 During welding, the tin paste in the shape of an ellipse is placed in the two copper welding openings 57. The welding head 418 heats the tin paste so that the tin paste is completely melted into the copper welding openings 57. At this time, the adjusting member 417 controls the movement of the first connecting member 413 on the first connecting member 413. Meanwhile, the scraper 419 scrapes the melted tin paste to the surface of the second steel substrate 56 so that the tin paste in the two copper welding openings 57 is connected. The second steel substrate 56 has a thickness smaller than that of the first steel substrate 55. After a layer of tin paste is applied to the surface of the second steel substrate 56, the thickness of the second steel substrate 56 is the same as that of the first steel substrate 55, which ensures the overall flatness of the welding process and improves the welding quality.

[0054] The above description is only the preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
