Description

Technical Field

[0001] This utility model relates to the technical field of LED string processing equipment, and in particular to a chip welding auxiliary stabilization mechanism for LED string production machines. Background Technology

[0002] LED string lights are widely used in indoor and outdoor decorative structures due to their rich colors and low energy consumption. An LED string light typically includes a light wire and several LED beads set on the light wire. The light wire contains several wires. The light wire has good overall insulation and good waterproof and moisture-proof effects, which allows the LED string light to be used outdoors. The use of light wires as string lights has been on the rise in recent years.

[0003] Existing LED light strings typically consist of two or more parallel wires, several LEDs mounted at certain intervals along the length of the wires, and encapsulating colloids that encapsulate the LEDs inside. During the production of such LED light strings, the LEDs need to be soldered to the wires. Before soldering the LEDs to the wires, a soldering mechanism needs to apply solder to the solder joints of the wires, and then a soldering mechanism is used to complete the soldering of the LED chips to the wires.

[0004] As disclosed in announcement number CN220407363U, an LED chip welding mechanism for a light string production equipment includes a transmission mechanism for conveying light wires. A welding mechanism is fitted to the side of the transmission mechanism to weld and fix LED chips onto the light wires. The welding mechanism includes a welding component, a welding wire assembly, and a pressure rod assembly. The welding component includes a welding piece, a welding base for mounting the welding piece, and a welding moving mechanism for moving the welding base. The welding wire assembly includes a welding wire holder, welding wire mounted on the welding wire holder, and a welding wire moving mechanism for moving the welding wire holder. The pressure rod assembly includes a chip pressure rod, a pressure rod base, and a pressure rod moving mechanism for moving the pressure rod base. The welding piece is located below the chip pressure rod. This invention features a simple structure, high welding precision, and high compatibility.

[0005] In existing light string production equipment, the LED chip and wire mounting mechanism and the soldering mechanism need to be connected by a transmission mechanism to transmit the light wires. As a result, during the transmission process, problems such as LED chip displacement and falling off are likely to occur, which will affect the production of the entire light string. Utility Model Content

[0006] To address the aforementioned issues, this utility model aims to provide a chip welding auxiliary stabilization mechanism for LED string production machines. By optimizing the welding auxiliary mechanism, the stability of LED chip transmission is improved, ensuring the LED chip welding effect.

[0007] The technical problem solved by this utility model can be achieved by the following technical solution: A chip welding auxiliary stabilizing mechanism for an LED string production machine includes a machine body with a wire clamping mechanism for clamping and transmitting LED wires. A string processing mechanism is arranged around the wire clamping mechanism, comprising several string processing units arranged sequentially around the wire clamping mechanism according to processing steps. The wire clamping mechanism includes several continuously arranged clamping mechanisms and a transmission mechanism for driving the clamping mechanisms in a cyclical manner. The machine also includes a welding auxiliary mechanism with several welding auxiliary clamps disposed on the wire clamping mechanism and transmitted synchronously with it. The welding auxiliary mechanism has a first limiting area, a welding auxiliary area, and a second limiting area. When the welding auxiliary clamp is within the first and second limiting areas, it separates from the LED wire or LED chip. When the welding auxiliary clamp is within the welding auxiliary area, it stabilizes the LED chip on the LED wire.

[0008] The welding auxiliary clamp includes an auxiliary base, a stabilizing clamp arm hinged to the auxiliary base, a linkage arm for moving the stabilizing clamp arm, and a limiting arm for moving the linkage arm. The limiting arm is provided with a limiting end. When the limiting end moves backward in a restricted manner, the limiting arm drives the linkage arm to lift the stabilizing clamp arm, thereby separating the welding auxiliary clamp from the lamp wire. When the limiting end does not make any contact, the stabilizing clamp arm moves downward and may contact the LED chip.

[0009] The welding auxiliary clamp is disposed within the clamping mechanism, which is provided with a plurality of clamping components. Each welding auxiliary clamp is provided with a clamping component on each of its adjacent sides. A single welding auxiliary clamp and two adjacent clamping components are combined to form a clamping unit. Each clamping mechanism is provided with at least one clamping unit.

[0010] The clamping mechanism includes a clamping base, and the clamping member is disposed on the clamping base. The clamping member includes a clamping arm and a reset member. The clamping base is provided with a plurality of first clamping hinge seats and a plurality of second clamping hinge seats. The clamping arm is used to hinge with the corresponding first clamping hinge seat and second clamping hinge seat. The upper end of the reset member is used to abut against the clamping arm, and the lower end of the reset member is used to abut against the clamping base.

[0011] It also includes a welding mechanism located on one side of the welding auxiliary area.

[0012] A first limiting member is provided in the first limiting area, extending along the transmission direction of the wire clamping mechanism, and is used to limit the limiting end in the welding auxiliary clamp; a second limiting member is provided in the second limiting area, extending along the transmission direction of the wire clamping mechanism, and is used to limit the limiting end in the welding auxiliary clamp.

[0013] A first transition frame is provided between the first limiting area and the welding auxiliary area, and a second transition frame is provided between the second limiting area and the welding auxiliary area. The area between the first transition frame and the second transition frame is the welding auxiliary area. When the welding auxiliary clamp is in the welding auxiliary area, the limiting end does not engage in any contact.

[0014] The first transition frame includes a first support and a first guide arm. When the welding auxiliary clamp enters the first guide arm, the limiting end of the welding auxiliary clamp disengages from the first limiting member and moves onto the first guide arm, whereby the limiting end engages with the side wall of the first guide arm. The second transition frame includes a second support and a second guide arm. When the welding auxiliary clamp enters the second guide arm, the limiting end of the welding auxiliary clamp changes from an unlimited contact state to being contacted by the second guide arm, whereby the limiting end engages with the side wall of the second guide arm.

[0015] One end of the first limiting member is installed in conjunction with the first limiting frame, and the other end is installed in conjunction with one end of the first guide arm. One end of the second limiting member is installed in conjunction with the second limiting frame, and the other end is installed in conjunction with one end of the second guide arm.

[0016] Both the first guide arm and the second guide arm have arc-shaped wall structures on their contact sidewalls.

[0017] Compared with the prior art, this utility model has the following advantages: This utility model optimizes the welding auxiliary mechanism and sets up a welding auxiliary area, so that the welding auxiliary clamp can stabilize the LED chip, avoid the LED chip from displacement or falling during transmission, change the instability problem of previous LED chip welding, and facilitate the welding mechanism to perform welding processing, thereby improving the welding effect between the LED chip and the wire.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Combination Figures 1 to 8 As shown, this utility model discloses a chip welding auxiliary stabilizing mechanism for an LED string production machine, including a body 100. A wire clamping mechanism 200 is provided on the body 100. The wire clamping mechanism 200 is used to clamp the lamp wire 110 and realize transmission. A string processing mechanism is arranged around the wire clamping mechanism 200. The string processing mechanism includes several string processing units. The string processing units are arranged sequentially around the wire clamping mechanism according to the processing steps. The string processing units vary depending on the specifications of the LED strings being processed. Based on existing LED string production machines, they typically include a wire feeding unit, a wire cutting unit, a spacing adjustment unit, a tinning unit, a chip mounting unit, a welding unit, a glue dispensing unit, and a curing unit.

[0022] In summary, the wire clamping mechanism 200 includes several continuously arranged clamping mechanisms 210 and a transmission mechanism 220 for driving the clamping mechanisms 210 to move in a cyclic manner. The transmission mechanism 220 can adopt existing transmission structures, such as CN220351011U, and typically includes a slide rail, a transmission wheel, a pulley and a drive mechanism. Preferably, a ring rail structure design is adopted, which can realize the arrangement of double wires.

[0023] In conjunction with the above, this embodiment preferably includes a welding auxiliary mechanism 400, which includes a plurality of welding auxiliary clamps 440. These clamps are mounted on the wire clamping mechanism 200 and are synchronously transmitted with it. The welding auxiliary mechanism 400 is provided with a first limiting area 410, a welding auxiliary area 430, and a second limiting area 420. When a welding auxiliary clamp 440 is within the first limiting area 410 and the second limiting area 420, it separates from the lamp wire 110 or the LED chip 120. When the welding auxiliary clamp 440 is within the welding auxiliary area 430, it is used to stabilize the LED chip 120 on the lamp wire 110. The preferred arrangement of the welding auxiliary mechanism 400 allows it to stabilize the LED chip 120 on the lamp wire 110 when it is within the welding auxiliary area 430. This improves the stability of the transmission and enhances the quality of the LED string processing as the LED chip 120 enters the welding process after the special patch is applied.

[0024] In its specific structure, the welding auxiliary clamp 440 includes an auxiliary base 443, a stabilizing clamping arm 441 hinged to the auxiliary base 443, a linkage arm 442 for moving the stabilizing clamping arm 441, and a limiting arm 444 for moving the linkage arm 442. The limiting arm 444 has a limiting end 445. When the limiting end 445 is restricted and moves backward, the limiting arm 444 drives the linkage arm 442 to lift the stabilizing clamping arm 441, thus separating the welding auxiliary clamp 440 from the lamp wire 110. When the limiting end 445 is not in contact with the lamp wire, the stabilizing clamping arm 441 moves downward and can contact the LED chip 120. One end of the stabilizing clamping arm 441 extends towards the lamp wire 110, allowing the stabilizing clamping arm 441 to move. The end of the clamping arm 441 can press against the upper part of the LED chip 120 to provide stable assistance for the transmission of the LED chip 120. The other end of the clamping arm 441 usually cooperates with the linkage arm 442, and the other end of the linkage arm 442 cooperates with the limiting arm 444. The limiting arm 444 moves accordingly as the limiting end 445 restricts its position, thereby completing the movement of the clamping arm 441 through linkage. When the limiting end 445 is restricted, the clamping arm 441 is usually in a raised state. As the restriction is gradually changed, the lifting height of the clamping arm 441 can be adjusted until there is no limit. Then, the clamping arm 441 is pressed down by gravity to complete the bonding of the LED chip 120 and achieve the voltage stabilization operation.

[0025] In conjunction with the above, the welding auxiliary clamp 440 is disposed within the clamping mechanism 210, which is provided with a plurality of clamping members 211. Each welding auxiliary clamp 440 has one clamping member 211 disposed on each of its adjacent sides. A single welding auxiliary clamp 440 and two adjacent clamping members 211 are combined to form a clamping unit. Each clamping mechanism 210 is provided with at least one clamping unit. In one preferred embodiment, a single clamping mechanism 210 includes two clamping units. The clamping members 211 are used to clamp the lamp wire 110, which facilitates the transmission of the lamp wire 110. Typically, in the pre-processing stripping process, the processing of the lamp wire 110 is performed between two clamping members 211. Therefore, the lamp wire 110 located between two clamping members 211 forms a bonding area for bonding the LED chip 120, which facilitates the pre-processing of the chip mounting. By placing the welding auxiliary clamp 440 between two adjacent clamping members 211, it is easier to press and stabilize the LED chip 120.

[0026] The clamping mechanism 210 includes a clamping base 2113, and a clamping member 211 disposed on the clamping base 2113. The clamping member 211 includes a clamping arm 2111 and a resetting member 2112. The clamping base 2113 is provided with a plurality of first clamping hinge seats 2115 and a plurality of second clamping hinge seats 2114. The clamping arm 2111 is used to hinge with the corresponding first clamping hinge seat 2115 and second clamping hinge seat 2114 for resetting. The upper end of component 2112 is used to abut against the clamping arm 2111, and the lower end of the reset component 2112 is used to abut against the clamping base 2113. The structure of the clamping mechanism 210 is optimized, and the clamping base 2113 is used to form an integral base unit, which facilitates the installation of multiple clamping components 211 on the clamping base 2113. In a preferred embodiment, a single clamping base 2113 is equipped with 4 clamping components 211 and 2 welding auxiliary clamps 440.

[0027] It also includes a welding mechanism 300, which is located on one side of the welding auxiliary area 430. The welding mechanism 300 is a commonly used LED chip welding mechanism, which can refer to the welding mechanism with announcement number CN220407363U; or it can use an existing hot air welding mechanism.

[0028] In the specific mechanism, the welding mechanism 300 is used to solder the LED chip 120 to the lamp wire 110. The welding mechanism 300 includes a hot air welding mechanism, which includes a preheating hot air welding unit 310 and a welding hot air welding unit 320. The hot air welding mechanism is a commonly used hot air welding equipment, which adopts double-port welding. By combining the preheating hot air welding unit 310 and the welding hot air welding unit 320, the stability of soldering is increased, and the welding efficiency is improved, thereby increasing the processing speed of the equipment.

[0029] In conjunction with the above, a first limiting member 411 is provided in the first limiting area 410, extending along the transmission direction of the wire clamping mechanism 200, and is used to limit the limiting end 445 in the welding auxiliary clamp 440; a second limiting member 421 is provided in the second limiting area 420, extending along the transmission direction of the wire clamping mechanism 200, and is used to limit the limiting end 445 in the welding auxiliary clamp 440; wherein, the first limiting member 411 and the second limiting member 421 are preferably made of steel wire, forming a limiting area, so that the limiting end 445 always abuts against the first limiting member 411 or the second limiting member 421, so that the stable clamping arm 441 at the other end is in a raised state, avoiding interference with the processing operations of other processes.

[0030] In the specific structure, one end of the first limiting member 411 is installed in conjunction with the first limiting frame 412, and the other end is installed in conjunction with one end of the first guide arm. One end of the second limiting member 421 is installed in conjunction with the second limiting frame 422, and the other end is installed in conjunction with one end of the second guide arm. This facilitates the installation of the first limiting member 411 and the second limiting member 421, and also facilitates the transition and movement of the welding auxiliary clamp 440.

[0031] In conjunction with the above, a first transition frame 450 is provided between the first limiting area 410 and the welding auxiliary area 430, and a second transition frame 460 is provided between the second limiting area 420 and the welding auxiliary area 430. The welding auxiliary area 430 is located between the first transition frame 450 and the second transition frame 460. When the welding auxiliary clamp 440 is in the welding auxiliary area 430, the limiting end 445 has no limit contact. The first transition frame 450 and the second transition frame 460 are optimized. When the welding auxiliary clamp 440 is transferred to the corresponding area, the first transition frame 450 can be used to... To achieve gradual movement and avoid large swings in the stabilizing clamp 441 in the welding auxiliary clamp 440, which would interfere with the lamp wire 110, as the first transition frame 450 continues to transition, at the end of the first transition frame 450, the stabilizing clamp 441 gradually adheres to the upper part of the LED chip 120, until it enters the welding auxiliary area 440 to achieve stable pressing of the LED chip 120, thus achieving a smooth transition. The second transition frame 460 is used to achieve gradual disengagement, improving the effect of the welding auxiliary clamp 440 in firmly pressing the LED chip 120.

[0032] In the specific structure, the first transition frame 450 includes a first support 452 and a first guide arm 451. When the welding auxiliary clamp 440 enters the first guide arm 451, the limiting end 445 in the welding auxiliary clamp 440 disengages from the first limiting member 411 onto the first guide arm 451, and the limiting end 445 engages with the side wall of the first guide arm 451 for limiting. The second transition frame 460 includes a second support 462 and a second guide arm 461. When the welding auxiliary clamp 440 enters the second guide arm 421, the welding auxiliary clamp 440... The limiting end 445 changes from an unlimited contact state to being contacted by the second guide arm 461, and the limiting end 445 and the side wall of the second guide arm 461 limit the engagement; the contact side walls of the first guide arm 451 and the second guide arm 461 both adopt an arc-shaped wall structure; the structure of the first guide arm 451 and the second guide arm 461 is optimized, and the arc transition is used to facilitate the gradual movement of the limiting end 445 in the welding auxiliary clamp 440, so that the end face of the stabilizing clamp arm 441 can gradually fit onto the LED chip 120 or gradually separate.

[0033] This utility model optimizes the use of a welding auxiliary mechanism and sets up a welding auxiliary area, which enables the welding auxiliary clamp to stabilize the LED chip, avoiding problems such as displacement or falling of the LED chip during transmission, and also facilitates the welding process of the welding mechanism, improving the welding effect between the LED chip and the wire.

[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
