[0028] The present application will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present application can be more easily understood and mastered.

[0029] Reference Figure 1 and Figure 2 This embodiment of a string light production fastening machine includes a machine body 1, on which a wire cutting mechanism 11 for cutting wires is provided. A first turntable 12 is also rotatably mounted on the machine body 1, and the wires cut by the wire cutting mechanism 11 fall onto the first turntable 12. The machine body 1 is also provided with a wire shaping mechanism 13 and a wire stripping mechanism 14. After the wires are cut and fall onto the first turntable 12, the shaping mechanism shapes the wires on the first turntable 12, and after shaping, the wire stripping mechanism 14 strips the shaped wires to expose the copper wires inside.

[0030] Reference Figure 1 and Figure 2 The machine body 1 is also equipped with a second turntable 16 that rotates, and a clamp for fixing the light bulb is arranged circumferentially above it. The machine body 1 is also equipped with a light bulb transmission mechanism 15 for transmitting light bulbs. The machine body 1 is also equipped with a clamping mechanism 17 and a light bulb detection and transmission mechanism 2. The light bulb transmission mechanism 15 is composed of multiple conveyor belts and multiple vibrating plates.

[0031] Reference Figures 1-3 The bulb detection and transmission mechanism 2 includes a detection head 21, a flipping mechanism 22, a first slide rod 23, and a second power unit. The detection head 21 is mounted on the output shaft of the flipping mechanism 22, which is mounted on the first slide rod 23. The first slide rod 23 is slidably mounted on the machine body 1. When the first slide rod 23 slides, it drives the detection head 21 to push qualified bulbs into the clamps of the second turntable 16. The second power unit is used to drive the slide rod to slide. In this application, the second power unit is a cylinder. The first slide rod 23 is connected to the output shaft of the second power unit, which is not shown in the figure.

[0032] Reference Figures 1-3 The clamping mechanism 17 is used to clamp the bulb on the bulb transfer mechanism 15 onto the detection station of the detection head 21. After the bulb is placed on the detection station of the detection head 21, the detection head 21 performs power-on and positive / negative polarity detection on the bulb. After the bulb is detected, the output shaft of the flipping mechanism 22 rotates to drive the detection head 21 and the bulb to rotate, so that the bulb faces the clamp on the second turntable 16. Then, the output shaft of the second power unit extends to drive the slide rod to slide, so that the detection head 21 pushes the bulb into the clamp of the second turntable 16, completing the bulb pushing.

[0033] Reference Figure 1 , Figure 2 , Figures 4-6 The body 1 is also equipped with a clamping mechanism 7, which is used to clamp the bulb base. The clamping mechanism 7 includes a second mounting bracket 71, two clamping blocks 72 hinged to the second mounting bracket 71, and a fifth power unit 73. A second channel 74 is formed between the two ends of the two clamping blocks 72 near the two ends of the second turntable 16 for the bulb base to pass through. When the bulb rotates with the second turntable 16, the bulb base will move into the second channel 74.

[0034] Reference Figures 4-6 The fifth power unit 73 is used to drive the two clamping blocks 72 to rotate, so that the two clamping blocks 72 clamp the lamp base of the bulb that enters the second channel 74. The fifth power unit 73 includes a rotating shaft 731 rotatably connected to the second mounting bracket 71, a top block 732 fixed to the rotating shaft 731, and a fifth power member that drives the rotating shaft 731 to reciprocate.

[0035] Reference Figure 6 The top block 732 is located between the two clamping blocks 72, and is also located on the side facing away from the second turntable 16 at the hinge point between the two clamping blocks 72 and the second mounting bracket 71. When the top block 732 rotates clockwise, it collides with the two clamping blocks 72 to drive the two ends near the second turntable 16 to move closer to each other. In this application, the fifth power component is a motor, and the output shaft of the fifth power component is connected to the rotating shaft 731. The fifth power component is not shown in the figure.

[0036] Reference Figure 1 and Figure 2 The main body 1 is also equipped with a terminal riveting mechanism 84. After the bulb's base is flattened, the terminal riveting mechanism 84 rivets the copper electrical terminals to the bulb's base. Flattening the bulb's base increases the contact area between the electrical terminals and the bulb base, thereby improving the riveting strength.

[0037] Reference Figure 1 , Figure 2 , Figures 7-8 The machine body 1 is also equipped with a riveting plate 85. The riveting plate 85 is located between the first turntable 12 and the second turntable 16. A second riveting plate 86 is also slidably connected to the machine body 1 in the vertical direction, and the second riveting plate 86 is located directly above the first riveting plate 85. The area where the rotation path of the wire on the first turntable 12 and the rotation path of the light bulb on the second turntable 16 overlaps is located between the first riveting plate 85 and the second riveting plate 86. When the light bulb and the wire move between the first riveting plate 85 and the second riveting plate 86, the electrical terminal contacts the exposed copper wire on the wire.

[0038] Reference Figure 1 , Figure 2 , Figures 7-10 The body 1 is also provided with a first drive mechanism 3 for driving the riveting plate 2 86 to slide. The first drive mechanism 3 drives the riveting plate 2 86 to slide down, so that the riveting plate 2 86 presses the copper wire and the electrical terminal on the wire together onto the riveting plate 1 85.

[0039] Reference Figures 7-10 The first drive mechanism 3 includes a first mounting bracket 31 mounted on the body 1.

A riveting plate 86 is fixed to the bottom end of the first slider 32.

[0040] Reference Figures 7-10 The first drive mechanism 3 further includes a drive block 33 disposed within the first mounting bracket 31 and connected to the first slider 32, an eccentric shaft 34 rotatably disposed on the first mounting bracket 31 and connected to the drive block 33, and a first drive unit for driving the eccentric shaft 34 to rotate. When the eccentric shaft 34 rotates, it drives the drive block 33 to reciprocate up and down. When the drive block 33 reciprocates up and down, it drives the first slider 32 and the riveting plate 86 to slide up and down, thereby controlling the movement of the riveting plate 86.

[0041] The first drive unit of this application includes a first sprocket mounted on an eccentric shaft 34, a motor mounted on a body 1, a second sprocket mounted on the output shaft of the motor, and a chain for connecting the first sprocket and the second sprocket. When the motor rotates, it drives the eccentric shaft 34 to rotate. The structure of the first drive unit of this application is not shown in the attached drawings.

[0042] Reference Figure 7 , Figure 8 and Figure 11 A first limiting plate 41 and a second limiting plate 42 are slidably mounted on the body 1 along the vertical direction. The first limiting plate 41 and the second limiting plate 42 are located on the side of the first riveting plate 85 near the first turntable 12, with the first limiting plate 41 located below the second limiting plate 42. A first channel 43 is formed between the first limiting plate 41 and the second limiting plate 42, through which the power supply line passes. The power line will pass through the first channel 43 as it rotates with the first turntable 12.

[0043] Reference Figure 7 , Figure 8 and Figure 11 The machine body 1 is also equipped with a third drive mechanism 5, which is used to drive the sliding of the limiting plate 41. The third drive mechanism 5 includes a second slide rod 51 that is slidably disposed on the machine body 1 in the vertical direction, a mounting rod 52 disposed on the second slide rod 51, and a third power unit that drives the second slide rod 51 to slide. The limiting plate 41 is mounted on the mounting rod 52. The third drive unit is a cylinder, and the second slide rod 51 is connected to the output shaft of the third drive unit. The third drive unit is not shown in the figure.

[0044] Reference Figure 7 , Figure 8 and Figure 11 The machine body 1 is also equipped with a fourth drive mechanism 6, which is used to drive the sliding of the second limiting plate 42. The fourth drive mechanism 6 includes a third slide rod 61 that is slidably disposed on the machine body 1 in the vertical direction, a second mounting rod 62 disposed on the third slide rod 61, and a fourth power unit that drives the third slide rod 61 to slide. The second limiting plate 42 is mounted on the second mounting rod 62. The fourth drive unit is a cylinder, and the third slide rod 61 is connected to the output shaft of the fourth drive unit. The fourth drive unit is not shown in the figure.

[0045] Reference Figure 7 , Figure 8 and Figure 11 The first limiting plate 41 has a limiting groove 44 for accommodating the wire, and the second limiting plate 42 has a second limiting block 45, which is inserted into the limiting groove 44. When the first limiting plate 41 and the second limiting plate 42 move closer to each other, the second limiting block 45 pushes the wire in and finally presses it into the limiting groove 44. Before the light bulb and the wire are riveted, the first limiting plate 41 and the second limiting plate 42 are used to clamp and fix the wire to prevent it from moving during riveting.

[0046] Reference Figure 1 and Figure 2 The main body 1 is also equipped with a riveting detection device 88 for pressing and detecting the riveting joint between the light bulb and the wire. After the wire and the light bulb are riveted together, the light bulb will rotate with the wire to a position below the riveting detection device 88. The pressing plate of the riveting detection device 88 will move down to press the riveting joint between the light bulb and the wire. If the riveting joint between the wire and the light bulb is secure, the pressing plate will move down and abut against the joint, and the downward movement of the pressing plate will be within a predetermined range. If the riveting joint between the wire and the light bulb is not secure, the downward movement of the pressing plate will break the joint, and the downward movement of the pressing plate will increase, exceeding the preset value. The secureness of the riveting joint between the wire and the light bulb is determined by identifying the downward movement distance of the pressing plate.

[0047] Reference Figure 1 and Figure 2 The machine body 1 is equipped with a spacer mounting mechanism 89, a lampshade mounting mechanism 90, a shrink film fitting mechanism 91, a heating mechanism 92, and a wire take-up mechanism 93. After the wire and bulb are inspected at the riveting point, the wire first rotates into the spacer mounting mechanism 89, which installs the spacer between the two bulb bases. Then, the wire and bulb rotate into the lampshade mounting mechanism 90, which fits the lampshade onto the bulb. Next, the wire and bulb rotate into the shrink film fitting mechanism 91, which fits the shrink film onto the outside of the lampshade. Then, the wire and bulb rotate into the heating mechanism 92, which heats the shrink film, causing it to shrink and wrap around the lampshade. Finally, the wire and bulb rotate into the wire take-up mechanism 93, which removes the wire from the first turntable 12.

[0048] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods.
