Description

Technical Field

[0001] This utility model relates to the field of light string production equipment, and in particular to a soldering machine for light string production. Background Technology

[0002] Traditional LED light strings use soldering machines to solder the bulbs and wires. However, in traditional LED soldering equipment, the bulbs are fed by a vibratory feeder.

[0003] There is a new type of LED light, such as Figure 9 As shown, the device includes a bulb body 91 and two lamp legs 92, with the lamp legs 92 featuring multi-segment bends. When using this device to manufacture LED strings, if the soldering machine uses a vibratory feeder, multiple bulbs can be squeezed together, causing the lamp legs 92 to easily deform or even bend due to this pressure, making soldering impossible. Therefore, a new type of soldering machine needs to be developed to meet the feeding and conveying requirements of new LED lights, enabling automated production of LED strings. Utility Model Content

[0026] 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.

[0027] Reference Figures 1-3 This embodiment of a soldering machine for producing light strings includes a machine body 1, a wire cutting mechanism 11, a first turntable 12, and a second turntable 13. When the wire cutting mechanism 11 is working, it cuts the wire bundle into segments, and then sends the cut wire segments to the processing station of the first turntable 12. The machine body 1 is also equipped with a first wire separation mechanism 14, a plastic shell feeding mechanism 15, a second wire separation mechanism 16, and a terminal riveting mechanism 8.

[0028] Reference Figures 1-3As the wires rotate with the first turntable 12, the first wire separation mechanism 14 first separates the two wires in the same processing station on the first turntable 12. Next, the plastic shell feeding mechanism 15 places the plastic shell onto the two wires in the same processing station. Then, the second wire separation mechanism 16 separates the two wires in the same processing station. Finally, the terminal crimping mechanism 8 crimps the copper terminals onto the wires, preparing for subsequent soldering.

[0029] Reference Figures 1-3 The machine body 1 is also equipped with a second turntable 13, which has multiple clamping parts distributed circumferentially for holding light bulbs. The machine body 1 is equipped with six vibratory feeders 17 for vibrating and transmitting light bulbs, a conveyor belt 19, and a first clamping mechanism 18 for holding light bulbs on the vibratory feeders 17. The conveyor belt 19 is located between the multiple feeding vibratory feeders 17 and is provided with multiple clamping parts for holding light bulbs.

[0030] Reference Figures 1-3 The machine body 1 is equipped with six clamping and detection mechanisms 4. The six clamping and detection mechanisms 4 are located between the conveyor belt 19 and the six first clamping mechanisms 18. The clamping and detection mechanisms 4 are used to clamp the bulb base on the first clamping mechanism 18 and clamp the bulb onto the clamping part of the conveyor belt 19, and to detect the positive and negative poles of the bulb when clamping it.

[0031] Reference Figures 4-6 The clamping and testing mechanism 4 includes a first mounting frame 41 mounted on the body 1, a rotating shaft 42 rotatably connected to the first mounting frame 41, a mounting base 43 mounted on the rotating shaft 42, two first sliding rods 44 slidably mounted on the mounting base 43 in the horizontal direction, two clamps 45 respectively mounted on the two first sliding rods 44, two electrode plates 46 respectively mounted on the two clamps 45, an insulating block 47 mounted on the mounting base 43 and located between the two clamps 45, a first drive assembly 48 for controlling the rotation of the rotating shaft 42, and a second drive assembly 49 for controlling the sliding of the two first sliding rods 44.

[0032] Reference Figures 4-6 The first drive assembly 48 includes a connecting block 481 connected at one end to a rotating shaft 42, a pull rod 482 hinged to the end of the connecting block 481 away from the rotating shaft 42, and a first drive unit for driving the pull rod 482 to move up and down. When the pull rod 482 moves up and down, it drives the rotating shaft 42 to rotate. In this application, the first drive unit is a cylinder, and the output shaft of the first drive unit is hinged to the pull rod 482. The first drive unit is not shown in the figure.

[0033] Reference Figures 4-6The mounting base 43 is provided with a separation plug 431. The separation plug 431 is located on the side of the insulating block 47 near the first clamping mechanism 18 and is in contact with the insulating block 47. As the mounting base 43 rotates, the separation plug 431 will insert the two lamp pins of the light bulb and guide the two lamp pins into both sides of the insulating block 47.

[0034] Reference Figures 4-6 The second drive assembly 49 includes a drive block 491 rotatably mounted on the mounting base 43, mating grooves 492 formed on the two first slide rods 44, an L-shaped rotating rod 493 hinged to the first mounting bracket 41, a push plate 494 located on one end of the L-shaped rotating rod 493, a roller 495 rolling on one of the first slide rods 44 and in contact with the push plate 494, a second drive unit for driving the L-shaped rotating rod 493 to rotate, and return springs 496 located at both ends on two clamps 45. In this application, the second drive unit is a cylinder, and the output shaft of the second drive unit is hinged to the end of the L-shaped rotating rod 493 away from the push plate 494. The second drive unit is not shown in the figure.

[0035] Reference Figures 4-6 The mounting base 43 includes a detachably connected body 432 and a cover plate 433. The mounting base 43 has two sliding grooves 434 and a mounting groove 435. The mounting groove 435 is located between and communicates with the two sliding grooves 434. Two first sliding rods 44 are slidably disposed within the two sliding grooves 434. The main body of the drive block 491 is rotatably disposed within the mounting groove 435, with its upper and lower ends extending into two mating grooves 492 respectively. When the machine is not started, the push plate 494 presses against the roller 495, causing the two clamps 45 to be in an open state. At this time, the return spring 496 is stretched by force.

[0036] Reference Figures 1-6 The working process of the clamping and testing mechanism 4 is as follows: When the machine is not started, the push plate 494 presses against the roller 495 under the action of the second drive unit, so that the two clamps 45 are in the open state and the return spring 496 is in the stretched state.

[0037] When it is necessary to clamp the light bulb on the first clamping mechanism 18, the first drive unit drives the pull rod 482 to move down, which drives the rotating shaft 42 to rotate forward through the connecting block 481, so that the mounting base 43 turns towards the first clamping mechanism 18. During this process, the separating insert 431 is first inserted between the two lamp legs of the light bulb, guiding the lamp legs into both sides of the insulating block 47; at the same time, the roller 495 always maintains contact with the push plate 494, and the clamp 45 remains open.

[0038] After the rotating shaft 42 stops rotating, the two clamps 45 move to the sides of the lamp base. Then, the second drive unit drives the L-shaped rotating rod 493 to rotate, causing the push plate 494 to move away from the roller 495. Under the restoring force of the return spring 496, the two first sliding rods 44 slide, causing the two clamps 45 to close, pressing the two electrode plates 46 tightly against the lamp base (the lamp base is located between the electrode plates 46 and the insulating block 47). At this time, the circuit is connected, and the positive and negative poles of the bulb can be detected.

[0039] After the inspection is completed, the first drive unit drives the rotating shaft 42 to reverse (rotate), sending the clamped bulb to the open clamping part on the conveyor belt 19 via the chuck 45. The clamping part on the conveyor belt 19 then holds the bulb. Next, the second drive unit drives the L-shaped rotating rod 493 to reset, and the push plate 494 moves towards the insulating block 47, pushing the roller 495 and the first slide rod 44, forcing the two chucks 45 to open against the force of the return spring 496, thereby releasing the bulb. The conveyor belt 19 then transports the bulb away, completing the bulb clamping and inspection process.

[0040] Reference Figures 1-3 The machine body 1 is also equipped with a second clamping mechanism 20 for clamping the light bulb on the conveyor belt 19 and placing the light bulb into the clamping part on the second turntable 13, a lamp foot direction conversion mechanism 21, a lamp foot shaping and separation mechanism 22, a lamp foot length detection mechanism 23, a light bulb clamping and flipping mechanism 24, a lamp foot outward V-shape shaping mechanism 25, and a lamp foot cutting mechanism 26.

[0041] Reference Figures 1-3 The bulb is transferred to the second turntable 13, where it rotates. During this process, the bulb pin orientation conversion mechanism 21 first rotates the bulb on the second turntable 13 so that the bulb pins are horizontal. Next, the bulb pin shaping and separating mechanism 22 separates the two bulb pins. Then, the bulb pin length detection mechanism 23 detects the length of the bulb pins. Next, the bulb clamping and flipping mechanism 24, based on the detection results of the bulb's positive and negative terminals by the clamping detection mechanism 4, clamps any defective bulbs and rotates them 180 degrees to ensure the positive and negative terminals are in the correct positions. Next, the bulb pin outward V-shape shaping mechanism 25 shapes the bulb pins so that they are outward V-shaped. Finally, the bulb pin cutting mechanism 26 cuts the shaped bulb pins to ensure the length meets welding requirements.

[0042] Reference Figures 1-3 , Figure 7 , Figure 8The machine body 1 is also equipped with a flux feeding mechanism 5. It is located between the first turntable 12 and the second turntable 13, and is used to adhere flux to the lamp base and the copper feet of the wires. The flux feeding mechanism 5 includes a container 51 for storing flux, a second mounting bracket 52, a second sliding rod 53 slidably mounted on the second mounting bracket 52 in a vertical direction, two scoops 54 mounted on the second sliding rod 53, and a third drive unit for driving the second sliding rod 53 to slide. When the two scoops 54 move downwards, they enter the container 51; when they move upwards, they scoop up flux and collide with the wires and lamp bases respectively during the upward movement, causing the flux to adhere to the wires and lamp bases. The third drive unit is a cylinder, and its output shaft is connected to the second sliding rod 53. The third drive unit is not shown in the figure.

[0043] Reference Figure 7 , Figure 8 The second slide bar 53 is provided with a first mounting block 55, the first mounting block 55 is provided with a first adjustment component 6 and a second adjustment component 7, the first adjustment component 6 is used to adjust the position of one of the scoops 54, and the second adjustment component 7 is used to adjust the position of the other scoop 54.

[0044] Reference Figure 7 , Figure 8 The first adjustment component 6 includes a second mounting block 61 disposed on the first mounting block 55, a third mounting block 62 disposed on the second mounting block 61, a first threaded hole 63 formed on the second mounting block 61, and an adjustment groove 64 formed on the third mounting block 62. A scoop 54 is disposed on the fourth mounting block. The fourth mounting block is fixed to the third mounting block 62 by bolts passing through the adjustment groove 64 and screwing into the first threaded hole 63. The adjustment groove 64 allows adjustment of the position of the fourth mounting block on the third mounting block 62, thereby adjusting the position of the scoop 54 so that flux can adhere to the lamp base when the scoop 54 moves up and down.

[0045] Reference Figure 7 , Figure 8 The second adjustment assembly 7 includes a mounting post 71 on the first mounting block 55, a fifth mounting block 72 on the mounting post 71, an adjustment cylinder 73 on the fifth mounting block 72, and a sixth mounting block 74 on the output shaft of the adjustment cylinder 73. Another scoop 54 is mounted on the sixth mounting block 74. The height of the scoop 54 can be adjusted by extending or retracting the output shaft of the adjustment cylinder 73.

[0046] Reference Figures 1-3 The machine body 1 is also equipped with a welding mechanism 27, a wire separation and shaping mechanism 28, a welding inspection mechanism 29, an isolation column installation mechanism 30, a sleeve installation mechanism 31, a heating mechanism 32, a plastic shell clamping and pushing mechanism 33, and a wire take-up mechanism 34.

[0047] Reference Figures 1-3 After flux is applied to the wires and lamp base, as the first turntable 12 and the second turntable 13 rotate, the wires and the light bulb move to the bottom of the welding mechanism 27, where they connect and are welded together. Once the light bulb and wire are welded, the clamping part on the second turntable 13 releases its grip on the light bulb, allowing it to rotate along with the wire.

[0048] Reference Figures 1-3 After the bulb and wires are soldered, the wire separation and shaping mechanism 28 separates the two wires soldered to the bulb. Next, the welding inspection mechanism 29 performs a pressure test on the solder joints of the wires and bulb. Then, the isolating post installation machine installs the isolating post between the two lamp bases. Next, the sleeve installation mechanism 31 places the sleeve onto the bulb. Then, the heating mechanism 32 heats the sleeve, causing it to shrink and tightly wrap around the bulb and isolating post. Next, the plastic shell clamping and pushing mechanism 33 holds the plastic shells on the two wires and pushes them onto the bulb, so that the plastic shells wrap around the connection between the bulb and the wires. Finally, the wire take-up mechanism 34 collects the processed light string.

[0049] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
