However, the glass is fragile, resulting in easy breakage of the lamp tube when clamping the LED lamp during the processing, and the traditional LED lamp processing device on the machine production line cannot fix multiple groups of LED lamps at the same time to assist in the processing of LED lamps, and the positioning and operation accuracy during the processing of LED lamps are insufficient, and the working efficiency of single-group clamping is also limited. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary fixture for LED lamp production to solve the problems raised in the above background art.

[0005] The technical solution of the present invention is: an auxiliary fixture for LED lamp production, including an industrial robot. A clamping structure is installed on one side of the industrial robot. An LED lamp structure is arranged at the middle position of the clamping structure. The LED lamp structure includes metal pins and a plastic lamp head, and the clamping structure clamps multiple groups of LED lamp structures. Among them, the clamping structure includes a double-headed telescopic push rod and a hinge assembly. The double-headed telescopic push rod drives the hinge assembly to move to clamp multiple groups of plastic lamp heads.

[0006] Furthermore, a protective lamp tube is installed at the top end of the plastic lamp holder. The protective lamp tube is U-shaped and there are two groups of it. The interior of the plastic lamp holder is hollow, and the bottom end of the plastic lamp holder penetrates through an LED chip. A metal wire is penetrated through one end of the LED chip close to the plastic lamp holder. A magnetic ring is fixed at the edge of the bottom end of the plastic lamp holder.

[0007] Furthermore, on one side of the bottom end of the LED chip, there are two groups of metal pins inlaid. The two groups of metal pins are in an outward-expanding shape.

[0008] Furthermore, the clamping structure further includes a U-shaped bracket, and one side of the U-shaped bracket is fixed to the industrial robot. A double-headed telescopic push rod is installed at the middle position of the U-shaped bracket.

[0009] Furthermore, the hinged assembly includes a first clamp and a second clamp. One end of the double-headed telescopic push rod is installed with a first hinge member. The double-headed telescopic push rod is hingedly connected to one end of the first clamp through the first hinge member. The end of the double-headed telescopic push rod far from the first clamp is hingedly connected to the second clamp.

[0010] Furthermore, a support back plate is installed on the side of the U-shaped bracket far from the industrial robot, and a limit groove is installed at the bottom end of the end of the support back plate far from the industrial robot.

[0011] Furthermore, a second hinge member is installed on the side of the support back plate close to the first clamp. The middle position of the first clamp is hingedly connected to the second hinge member. A fixed side plate is installed on the side of the support back plate close to the second clamp. The second clamp is in an L-shaped shape. The bent part of the second clamp is hingedly connected to the fixed side plate.

[0012] Furthermore, a triangular clamping plate is hingedly connected to the end of the second clamp close to the LED lamp structure. The triangular clamping plate is in a triangular shape. One side of the triangular clamping plate is hingedly connected to a first clamping plate. The side of the triangular clamping plate far from the first clamping plate is hingedly connected to a second clamping plate. Both the second clamping plate and the first clamping plate are in a triangular shape.

[0013] Furthermore, a limit slide rail is installed at the bottom end inside the limit groove, and a magnetic slider is installed at the top end of the limit slide rail. A magnetic support groove is installed at the top end of the magnetic slider, and the magnetic support groove is snap-fitted with the bottom end of the LED chip.

[0014] The present invention hereby provides an auxiliary fixture for LED lamp production through improvement. Compared with the prior art, it has the following improvements and advantages: First, the clamping structure can fix multiple groups of LED lamp structures simultaneously. The position where the clamping structure clamps is the plastic lamp head, which is made of plastic and has elasticity, avoiding the protective lamp tube from being broken due to the force applied by the first clamp and the second clamp. The clamping structure cooperates with the start of the double-headed telescopic push rod and the transmission component, so that the first clamps and the second clamps on both sides apply force towards the LED lamp structure at the middle position at the same time, thus holding multiple groups of LED lamp structures, being able to fix multiple groups of LED lamps simultaneously, and thus assisting in the processing of LED lamps. Compared with the traditional single-group clamping method, this structure has higher working efficiency, can fix multiple groups of lamps at the same time, and can process multiple groups of lamps at the same time. In other processing methods such as the bending of lamp pins, this device can assist in fixing the lamps, improving the positioning and operation accuracy of the lamps during processing. In addition, the functions of the triangular clamping plate, the second clamping plate, and the first clamping plate are such that through the characteristics of being movable and flipable, the second clamp can cooperate with the size of the plastic lamp head during clamping, and the plastic lamp heads can be automatically aligned as the flipping angle of the second clamp gradually increases.

[0015] Second, the magnetic ring and the magnetic support groove attract each other through magnetism. During use, the overall LED lamp structure moves during the clamping process. At this time, because the magnetic ring and the magnetic support groove are fixed by magnetic attraction, the special-shaped outer shapes of the magnetic ring and the magnetic support groove cooperate with each other for magnetic attraction, which can fix the position of the top lamp tube, thus avoiding the cylindrical lamp tube from rotating and shifting its position during clamping. Moreover, the magnetic support groove and the magnetic slider at the bottom will be driven by the LED lamp structure to slide on the limit slide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will combine the attached Figures 1 to 8 The present invention will be described in detail. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0019] The present invention provides an auxiliary fixture for LED lamp production by improvement, which includes an industrial robot 1. A clamping structure 3 is installed on one side of the industrial robot 1. An LED lamp structure 2 is arranged at the middle position of the clamping structure 3. The LED lamp structure 2 includes a metal pin 205 and a plastic lamp holder 202, and the clamping structure 3 clamps multiple groups of LED lamp structures 2. A protective lamp tube 201 is installed at the top end of the plastic lamp holder 202. The protective lamp tube 201 is U-shaped and there are two groups. The inside of the plastic lamp holder 202 is hollow, and an LED chip 204 penetrates through the bottom end of the plastic lamp holder 202. A metal wire 203 penetrates through one end of the LED chip 204 close to the plastic lamp holder 202. A magnetic ring 206 is fixed at the edge of the bottom end of the plastic lamp holder 202. One side of the bottom end of the LED chip 204 is inlaid with a metal pin 205, and there are two groups of metal pins 205. The two groups of metal pins 205 are in an outwardly expanding shape. Among them, the clamping structure 3 includes a double-headed telescopic push rod 302 and a hinge assembly. The double-headed telescopic push rod 302 drives the hinge assembly to move to clamp multiple groups of plastic lamp holders 202; through the clamping structure 3, multiple groups of LED lamp structures 2 can be fixed simultaneously. The clamping structure 3 further includes a U-shaped bracket 301, and one side of the U-shaped bracket 301 is fixed to the industrial robot 1. A double-headed telescopic push rod 302 is installed at the middle position of the U-shaped bracket 301. The articulated assembly includes a first clamping clip 304 and a second clamping clip 307. One end of the double-headed telescopic push rod 302 is equipped with a first articulated member 303. The double-headed telescopic push rod 302 is articulated and connected to one end of the first clamping clip 304 through the first articulated member 303. The end of the double-headed telescopic push rod 302 far from the first clamping clip 304 is articulated and connected to the second clamping clip 307. By starting the double-headed telescopic push rod 302 and cooperating with the transmission assembly, the clamping structure 3 enables the first clamping clips 304 and the second clamping clips 307 on both sides to apply force simultaneously towards the direction of the LED lamp structure 2 at the middle position, thereby clamping multiple groups of LED lamp structures 2, being able to fix multiple groups of LED lamps simultaneously, thus assisting in the processing of LED lamps. Compared with the traditional single-group clamping method, this structure has higher working efficiency, can fix multiple groups of lamps simultaneously, and can process multiple groups of lamps simultaneously. In other processing methods such as the bending of lamp pins, this device can assist in fixing the lamps, improving the positioning and operation accuracy of the lamps during processing; Moreover, the position clamped by the clamping structure 3 is the plastic lamp head 202. The plastic lamp head 202 is made of plastic and has elasticity, avoiding the cracking of the protective lamp tube 201 caused by the force applied by the first clamping clip 304 and the second clamping clip 307; On the side of the U-shaped bracket 301 far from the industrial robot 1, a support back plate 306 is installed, and a limit groove 312 is installed at the bottom end of the end of the support back plate 306 far from the industrial robot 1; On the side of the support back plate 306 close to the first clamping clip 304, a second articulated member 305 is installed. The middle position of the first clamping clip 304 is articulated and connected to the second articulated member 305. On the side of the support back plate 306 close to the second clamping clip 307, a fixed side plate 308 is installed. The second clamping clip 307 has an L-shaped outer shape, and the bent part of the second clamping clip 307 is articulated and connected to the fixed side plate 308; The specific working principle of the clamping structure 3 is through the linkage of multiple parts. When the double-headed telescopic push rod 302 is started, both ends expand and contract simultaneously. When the output ends of the double-headed telescopic push rod 302 extend simultaneously, they drive the first clamping clips 304 and the second clamping clips 307 on both sides to flip. The first clamping clip 304 is articulated to the support back plate 306 through the second articulated member 305, and the second clamping clip 307 is connected to the support back plate 306 through the articulated point of the fixed side plate 308. After the double-headed telescopic push rod 302 is started, the first clamping clip 304 and the second clamping clip 307 respectively flip around the articulated points of the second articulated member 305 and the fixed side plate 308 to clamp the LED lamp structure 2 at the middle position of the support back plate 306, thereby fixing multiple groups of LED lamp structures 2. Additionally, when the second clamping clip 307 flips around the articulated point of the fixed side plate 308, the triangular clamping plate 309, the first clamping plate 310, and the second clamping plate 311 approach the LED lamp structure 2, and the wide ends of the first clamping plate 310 and the second clamping plate 311 can automatically arrange multiple groups of LED lamp structures 2 side by side, facilitating subsequent operations on the LED lamp structure 2; One end of the second clamping clip 307 close to the LED lamp structure 2 is hingedly connected with a triangular clamping plate 309, and the triangular clamping plate 309 has a triangular outer shape. One side of the triangular clamping plate 309 is hingedly connected with a first clamping plate 310, and the side of the triangular clamping plate 309 away from the first clamping plate 310 is hingedly connected with a second clamping plate 311. Both the second clamping plate 311 and the first clamping plate 310 have a triangular outer shape. The functions of the triangular clamping plate 309, the second clamping plate 311 and the first clamping plate 310 are, through the characteristics of being movable and flippable, to enable the second clamping clip 307 to cooperate with the size of the plastic lamp head 202 during clamping, and to automatically align the plastic lamp head 202 as the flipping angle of the second clamping clip 307 gradually increases; A limit slide rail 313 is installed at the bottom end inside the limit groove 312, and a magnetic slider 314 is installed at the top end of the limit slide rail 313. A magnetic force support groove 315 is installed at the top end of the magnetic slider 314, and the magnetic force support groove 315 is snap-fitted with the bottom end of the LED chip 204; The magnetic force ring 206 and the magnetic force support groove 315 attract each other by magnetic force. When the LED lamp structure 2 as a whole moves during the clamping process, since the magnetic force ring 206 and the magnetic force support groove 315 are fixed by magnetic attraction, and the special-shaped outer shapes of the magnetic force ring 206 and the magnetic force support groove 315 cooperate with each other for magnetic attraction, the position of the top lamp tube can be fixed, thereby preventing the cylindrical lamp tube from rotating and shifting its position during the clamping process. Moreover, the magnetic force support groove 315 and the magnetic slider 314 at the bottom end will slide on the limit slide rail 313 driven by the LED lamp structure 2.

[0020] Working principle: First, start the double-headed telescopic push rod 302, and it extends and retracts at both ends simultaneously. When the output ends of the double-headed telescopic push rod 302 extend out simultaneously, they drive the first clamping clip 304 and the second clamping clip 307 on both sides to flip. The first clamping clip 304 is hingedly connected to the support back plate 306 through the second hinge 305, and the second clamping clip 307 is connected to the support back plate 306 through the fixed side plate 308. The hinge points enable the first clamping clip 304 and the second clamping clip 307 to flip around the hinge points of the second hinge 305 and the fixed side plate 308 respectively towards the LED lamp structure 2 located in the middle of the support back plate 306 for clamping after the double-headed telescopic push rod 302 is started, thereby fixing multiple groups of LED lamp structures 2. Additionally, when the second clamping clip 307 flips around the hinge point of the fixed side plate 308, the triangular clamping plate 309, the first clamping plate 310 and the second clamping plate 311 approach the LED lamp structure 2, and the wide-edge ends of the first clamping plate 310 and the second clamping plate 311 can automatically arrange multiple groups of LED lamp structures 2 side by side, facilitating subsequent operations on the LED lamp structure 2.

[0021] Then, through the magnetic attraction between the magnetic ring 206 and the magnetic bracket 315, during use, the entire LED lamp structure 2 moves its position during the clamping process. At this time, because the magnetic ring 206 and the magnetic bracket 315 are fixed by magnetic attraction, and the special-shaped outer shapes of the magnetic ring 206 and the magnetic bracket 315 cooperate with each other for magnetic attraction, the position of the top lamp tube can be fixed, thus preventing the cylindrical lamp tube from rotating and shifting its position during the clamping process. Moreover, the magnetic bracket 315 and the magnetic slider 314 at the bottom will slide on the limit slide rail 313 along with the LED lamp structure 2.

[0022] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
