Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of LED light string processing equipment, in particular to an LED light string production machine. BACKGROUND

[0002] LED light strings are widely used in indoor or outdoor decorative structures due to their rich colors and low energy consumption. The LED light string generally includes a lamp wire and a plurality of lamp beads arranged on the lamp wire. The lamp wire has good insulation and good waterproof and moisture-proof effect, so that the LED light string can be used outdoors. In recent years, the price of lamp wire as LED light string has been rising.

[0003] The existing LED light string is usually composed of two or more parallel arranged wires, a plurality of LEDs attached to the wires at certain intervals along the length direction of the wires, and a packaging gel encapsulating the LEDs. During production, the LEDs need to be welded to the wires. Before welding the LEDs to the wires, a tin point mechanism is needed to point tin at the welding point position of the wires, and then a welding mechanism is used to complete the welding of the LED chip to the wires.

[0004] As disclosed in the publication number CN116902516B, a ring rail type double station LED light string production equipment is disclosed, which includes a ring rail type transmission mechanism for clamping the lamp wire and realizing intermittent transmission. The ring rail type transmission mechanism is arranged around the lamp string processing module. The ring rail type transmission mechanism includes two oppositely arranged transmission straight rails, a transmission curved rail for connecting the two transmission straight rails, and a plurality of wire clamping units moving along the transmission straight rails and the transmission curved rails. The wire clamping units are used to clamp the lamp wire and realize intermittent transmission along the transmission straight rails. The lamp string processing module is divided into two processing module groups, and a single processing module group is arranged on a single transmission straight rail. The present application optimizes the design of the ring rail type transmission mechanism, and utilizes the transmission straight rails on both sides to cooperate with the wire clamping units to realize the transmission of two-way double lamp wires. The multiple lamp string processing mechanisms required for LED light string processing are matched to realize processing of different processes, so that a single machine can complete double station processing.

[0005] In the existing light string production equipment, the tin point mechanism and the welding mechanism of the LED chip and the wire need to realize the transmission of the lamp wire through the transmission mechanism. Therefore, during the transmission process, the LED chip is prone to displacement and falling, which affects the production of the entire light string. In addition, the existing LED light string production equipment is usually only suitable for completing the lamp bead light string after gluing. If a lampshade structure needs to be added to the outside of the lamp bead, it needs to be assembled and processed separately, which makes the production relatively complicated and the manufacturing cost and efficiency relatively low.

[0051] When the lamp wire 100 after stripping is transmitted with the wire clamping mechanism 1500, it is transmitted to the distance adjusting mechanism 500. The distance adjusting mechanism 500 is used to adjust the interval distance of the stripping area on the lamp wire 100.

[0054] When the lamp wire 100 after polishing is transmitted with the wire clamping mechanism 1500, it is transmitted to the tin plating assembly mechanism 800, which is used to realize the tin plating treatment of the corresponding wire 102 in the lamp wire 100. The tin plating assembly mechanism 800 includes a first tin plating unit 810, a second tin plating unit 820 and a third tin plating unit 830, and the first tin plating unit 810 is subsequently arranged with a tin paste heating unit 840.

In a specific embodiment, during the entire lamp string processing process, series connection is required between two adjacent LED lamp strings 101, and corresponding wire breaking treatment is performed. For example, an entire LED lamp string 101 includes 200 LED lamp beads, and each 50 LED lamp beads is a lamp string unit. The single-wire connection between adjacent lamp string units needs to be processed by the wire breaking mechanism 850. In other embodiments, according to different specifications of the LED lamp string 101, the wire breaking mechanism 850 can also be used as a cut signal wire.

When the welding auxiliary clamp 1640 is in the first limiting area 1610 and the second limiting area 1620, the welding auxiliary clamp 1640 is separated from the lamp wire 100. When the welding auxiliary clamp 1640 is in the welding auxiliary area 1630, the welding auxiliary clamp 1640 is used to stabilize the LED chip 103 on the lamp wire 100.

[0061] In combination with the above, the first limiting member 1611 is arranged in the first limiting area 1610 and extends along the transmission direction of the wire clamping mechanism 1500, and is used to limit the limiting end 1645 of the welding auxiliary clamp 1640; the second limiting member 1621 is arranged in the second limiting area 1620 and extends along the transmission direction of the wire clamping mechanism 1500, and is used to limit the limiting end 1645 of the welding auxiliary clamp 1640; wherein the first limiting member 1611 and the second limiting member 1621 are usually preferably steel wires, forming a limiting area, so that the limiting end 1645 always interferes on the first limiting member 1611 or the second limiting member 1621, so that the stable clamp arm 1641 at the other end is in a lifted state, to avoid interference with the processing operation of the remaining procedures.

[0062] In a specific structure, one end of the first limiting member 1611 is matched and installed with the first limiting frame 1612, and the other end is matched and installed with one end of the first wire arm 1651; one end of the second limiting member 1621 is matched and installed with the second limiting frame 1622, and the other end is matched and installed with one end of the second wire arm 1661; which facilitates the installation of the first limiting member 1611 and the second limiting member 1621, and facilitates the transition transmission and movement of the welding auxiliary clamp 1640.

[0063] In combination with the above, the first limiting area 1610 and the welding auxiliary area 1630 are provided with a first transition frame 1650, the second limiting area 1620 and the welding auxiliary area 1630 are provided with a second transition frame 1660, and the welding auxiliary area 1630 is between the first transition frame 1650 and the second transition frame 1660. When the welding auxiliary clamp 1640 is in the welding auxiliary area 1630, the limiting end head 1645 is not limited and interfered. The first transition frame 1650 and the second transition frame 1660 are optimized.
