[0028] The following is combined with Figures 1 to 2 The present invention will be described in detail.

[0029] The present invention mainly belongs to the field of LED manufacturing, and specifically is an automatic forming process for a lamp stem, comprising the following steps:

[0030] S1, unwinding the braid 5 with resistors and conductors arranged thereon from a reel;

[0031] S2. The braid 5 passes through the mold 1 for forming the lamp holder, and the resistor and the wire correspond to the cavity of the mold 1; the resistance of the resistor element is between 0.1 and 100K ohms. The cavity of the mold can be single, but the best way is to use multiple arrangements, so that multiple lamp cores can be formed at a single time.

[0032] S3. The mold is combined to form the lamp holder 6, and the resistor and the wire are injection molded with the lamp holder; the material of the lamp holder is preferably PTE, which can withstand high temperatures up to 150 degrees Celsius, can adapt to the heat of most lamps, and can also provide a soft surface for sealing the lamp housing and waterproofing the wick, thereby improving the waterproof performance when used outdoors and making the product more reliable in waterproof performance.

[0033] S4, the mold is opened, and the molded lamp holder is demoulded from the mold cavity;

[0034] S5, recycling the braided tape with the lamp holder formed thereon;

[0035] S6, looping to form the next group of lamp holders.

[0036] Obviously, the above process has the following technical advantages: it saves assembly steps, and only needs to pass the braid with resistors and wires directly through the mold to form it with the lamp holder at the same time, without the need for separate assembly. The molding speed is fast, and multiple lamp cores can be molded at a time, saving assembly time and helping to increase production capacity. Since there is no need for further assembly, it can reduce production labor, with a high degree of automation and labor cost savings.

[0037] As a further optimization of this process, before step S1, a braiding process is also included, wherein the braiding process includes: first forming a resistor braid and a conductor braid, and then merging the resistor braid and the conductor braid into a composite braid. The resistor braid is mainly formed by directly pasting the leads 42 and 43 at both ends of the resistor on the corresponding braid. Similarly, the conductor braid is formed by directly pasting the conductor on the corresponding braid at a specified spacing. Then, the two braids are compounded so that the resistor and the conductor are stacked together at a predetermined spacing and can be fixed with tape. Usually, the spacing between the resistor and the conductor is between 1 and 30 mm.

[0038] In step S5, the formed lamp stem is still connected to the braid, and the recycling is performed by an automatic winding device. The recycling can be wound by a reel, which is conducive to the subsequent automatic release.

[0039] Of course, on the basis of multiple cavities, in step S2, the cavities of the mold are provided with at least two groups. For example, they are divided into upper and lower groups, each group contains multiple cavities, and correspondingly, the braids are also released in the corresponding upper and lower groups. In this way, the molding efficiency of the lamp stem can be doubled.

[0040] For a preferred embodiment, after step S6, an automatic cutting step is provided, in which the lead wire 42 of the resistor is cut using an automatic cutting tool. The purpose of cutting is to accurately reserve the welding position of the LED light bar 3, so as to facilitate the welding of the LED light bar. After the cutting step, a bending step is provided, in which an upper end of the wire 2 is bent to form a bending portion 21, and the bending portion is made to correspond to the lead wire. After the bending step, a welding step is provided, in which the LED light bar is welded to the bending portion and the lead wire.

[0041] After the LED light strips are welded, a head cutting step is provided, wherein a cutting tool is used to separate the formed lamp stem from the braid. In this way, the stem with the LED light strips can be directly used for the finished lamp assembly.

[0042] Of course, as another preferred embodiment:

[0043] After step S6, a head cutting step is first performed, wherein a cutting tool is used to separate the formed lamp stem from the braid. Then a shearing step is set up, wherein the lead wire of the resistor is cut using a shearing tool. The purpose of shearing is to accurately reserve the welding position of the LED light bar 3, so as to facilitate welding of the LED light bar. After the shearing step, a bending step is set up, wherein the upper end of the wire is bent to form a bending portion, and the bending portion is made to correspond to the lead wire. After the bending step, a welding step is set up, wherein the LED light bar is welded to the bending portion and the lead wire.

[0044] After the LED light strip is welded, the core column with the LED light strip can be directly used for the finished assembly of the lamp.

[0045] As a further optimization of this process, the wire is a metal wire with a diameter of 0.1 to 1.0 mm, and the diameter of the lead wire is 0.1 to 1.0 mm, so that the metal wire can also support the entire lamp core column, so that it has a certain supporting strength. The two ends of the resistor are metal end caps 44, and the leads 42 and 43 are connected to the metal end caps by butt welding. This welding efficiency is high and the welding quality is good.

[0046] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
