Description

Technical Field

[0001] This utility model belongs to the field of LCD TV assembly technology, and in particular relates to an optimized material conveying rack for LCD TV assembly lines. Background Technology

[0002] A liquid crystal display television (LCD TV) is a television device that uses liquid crystal display technology to display images. It has become a common audio-visual device in modern homes. Since its inception, LCD TVs have undergone continuous technological innovation and development, gradually evolving from early low resolution and large bezels to today's high resolution, narrow bezels, and ultra-thin designs.

[0003] In the production and assembly process of LCD TVs, different sides of the LCD TV need to be assembled or tested. Existing conveyor racks usually use a linear conveying method, which means that when wire harnesses or components need to be assembled on different sides of the LCD TV, workers need to manually adjust them to the appropriate assembly surface, resulting in slow operation speed and low assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an optimized material conveying rack for LCD TV assembly lines. By combining the specific structures of the rotating component and the limiting component, it solves the problem of low assembly efficiency caused by manual adjustment of component assembly surfaces in the aforementioned background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an optimized material conveying rack for LCD TV assembly lines, including a conveying rack body; two guide rails are symmetrically fixed at the top of the conveying rack body, and a rotating component is slidably arranged between the two guide rails. A rack that cooperates with the rotating component is slidably arranged inside one of the guide rails. The rotating component includes a convex plate, and a lead screw is threadedly connected inside the convex plate. The lead screw is rotatably connected inside the other guide rail. A bearing plate is rotatably arranged at the top of the convex plate, and a gear one and a gear two are rotatably connected at the bottom of the convex plate. The tooth end of gear one meshes with one side of the tooth end of gear two, and the other side of the tooth end of gear two meshes with the rack. Several through grooves are opened inside one of the guide rails, and a limiting component that cooperates with the rack is slidably arranged inside the through grooves.

[0006] The present invention is further configured such that the limiting component includes a connecting rod and two circular rods. One end of the connecting rod is rotatably connected to a rack, and one end of each of the two circular rods is fixedly connected to the rack. A limiting plate is fixedly connected inside the through groove. Both the connecting rod and the circular rods pass through the limiting plate. A limiting ring is fixedly connected to the outer wall of the connecting rod. A circular ring is sleeved on the outer wall of the connecting rod and fixedly connected to the through groove. A fastening ring is slidably arranged inside the circular ring. A stop rod is fixedly connected to one side of the connecting rod and passes through the fastening ring. Limiting grooves are symmetrically opened on both sides of the inner wall of the through groove. Limiting rods that cooperate with the limiting rings are slidably arranged inside the two limiting grooves.

[0007] The present invention is further provided that each of the two guide rails has a groove on one of its adjacent sides that is used to cooperate with the convex plate.

[0008] The present invention is further configured such that a rotating shaft is rotatably connected to the lower surface of the bearing plate, and one end of the rotating shaft passes through the convex plate and is rotatably connected to the middle of the gear.

[0009] The present invention is further configured such that springs are fitted on the outer walls of both circular rods, and the two ends of the springs are respectively fixedly connected to one side of the limiting plate.

[0010] The present invention is further configured such that a return spring is fixedly connected to the inner bottom surface of the two limiting grooves, the other end of the return spring is fixedly connected to the end of the limiting rod, and two grooves are symmetrically opened on the outer wall of the limiting ring to cooperate with the limiting grooves.

[0011] The present invention is further configured such that the inner wall of the circular ring is provided with a thread 1, the outer wall of the stop bar is provided with a thread 3, the outer wall of the fastening ring is provided with a thread 2 that is used to cooperate with the thread 1, and the inner wall of the fastening ring is provided with a thread 4 that is used to cooperate with the thread 3.

[0012] The present invention is further configured such that a plurality of guide rods are fixedly connected to the lower surface of the bearing plate, and an annular groove for use with the guide rods is formed on the upper surface of the convex plate.

[0013] The present invention has the following beneficial effects: 1. The present invention uses the rotating roller on the conveyor frame to contact the square block at the bottom of the convex plate, thereby moving the convex plate and placing the assembly materials of the LCD TV onto the carrier plate for assembly. When the convex plate moves to the vicinity of the rack, the second gear at the bottom of the convex plate contacts and meshes with the rack. The rotation of the second gear drives the first gear and the rotating shaft to rotate. The rotation of the rotating shaft drives the guide rod on the lower surface of the carrier plate to rotate in the annular groove on the surface of the convex plate. At this time, the display screen on the carrier plate rotates to a direction that is convenient for workers to operate, so as to carry out the assembly operation and improve the assembly efficiency.

[0014] 2. When the bearing plate does not need to rotate the components, the rotating stop rod drives the connecting rod and the limiting ring on the outer surface of the connecting rod to rotate together. Then, pulling the stop rod drives the connecting rod, the limiting ring, and the rack to move together. During the movement of the connecting rod, the conical surface on one side of the limiting ring on the outer surface of the connecting rod contacts the inclined surface of the limiting rod in the limiting groove, pushing the limiting rod to move, so that the plane of the limiting rod contacts one side of the plane of the limiting ring to limit the connecting rod. At this time, the rack and gear 2 do not contact each other, the bearing plate does not rotate, and the stop rod is rotated counterclockwise. The connecting rod and the limiting ring rotate. When the groove on the surface of the limiting ring matches the position of the limiting rod, the spring outside the circular rod generates elastic potential energy during the movement of the rack. At this time, the elastic potential energy is released, pushing the rack to extend. The thread two on the outer wall and the thread four on the inner wall of the rotating fastening ring are respectively connected to the thread three on the outer wall of the stop rod and the thread one on the inner wall of the circular ring. At this time, the stop rod is fixed, and the rack cannot retract. Thus, it can mesh with the second gear and drive the second gear to rotate, thereby realizing the retraction and extension of the rack to meet different assembly requirements.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] For a specific implementation example, please refer to Implementation Example 1. Figure 1-10This utility model is an optimized material conveying rack for an LCD TV assembly line, comprising a conveying rack body 1. Specifically, two guide rails 4 are symmetrically fixed to the top of the conveying rack body 1, and a rotating assembly 3 is slidably arranged between the two guide rails 4. A rack 5 is slidably arranged inside one of the guide rails 4 to cooperate with the rotating assembly 3. The rotating assembly 3 includes a convex plate 302, and a lead screw 303 is threadedly connected inside the convex plate 302. The lead screw 303 is rotatably connected inside the other guide rail 4. A groove 201 for cooperating with the convex plate 302 is opened on an adjacent side of both guide rails 4. A bearing plate 301 is rotatably arranged on the top of the convex plate 302. Multiple guide rods 306 are fixedly connected to the lower surface of the convex plate 302. An annular groove 307 for cooperating with the guide rods 306 is opened on the upper surface of the convex plate 302. Gear 1 304 and gear 2 305 are rotatably connected to the bottom of the convex plate 302 respectively. The tooth end of gear 1 304 meshes with one side of the tooth end of gear 2 305, and the other side of the tooth end of gear 2 305 meshes with the rack 5. A rotating shaft 308 is rotatably connected to the lower surface of the bearing plate 301. One end of the rotating shaft 308 passes through the convex plate 302 and is rotatably connected to the middle of gear 1 304. Several through grooves 6 are opened inside the other guide rail 4. A limiting component 2 for cooperating with the rack 5 is slidably arranged inside the through groove 6.

[0031] The operation process of this embodiment is as follows: Start the external motor, which drives the lead screw 309 to rotate. The rotation of the lead screw 309 causes the convex plate 302 to move on the conveyor frame body 1, placing the LCD TV display assembly material on the carrier plate 301 for assembly. When it is necessary to assemble other positions of the display screen, when the convex plate 302 moves to the vicinity of the rack 5, the second gear 305 at the bottom of the convex plate 302 contacts and meshes with the rack 5. The rotation of the second gear 305 causes the first gear 304 to rotate. The rotation of the first gear 304 causes the rotating shaft 308 to rotate. The rotation of the rotating shaft 308 causes the guide rod 306 on the lower surface of the carrier plate 301 to rotate in the annular groove 307 on the surface of the convex plate 302. At this time, the display screen on the carrier plate 301 is rotated to a direction that is convenient for the worker to operate, and the assembly operation is carried out.

[0032] For a specific embodiment two, please refer to Figure 7-10Based on the first specific embodiment, the limiting component 2 includes a connecting rod 204 and two circular rods 205. Specifically, one end of the connecting rod 204 is rotatably connected to the rack 5, and one end of each of the two circular rods 205 is fixedly connected to the rack 5. A limiting plate 210 is fixedly connected inside the through groove 6. Both the connecting rod 204 and the circular rods 205 pass through the limiting plate 210. Springs 209 are sleeved on the outer walls of the two circular rods 205. The two ends of the springs 209 are fixedly connected to one side of the limiting plate 210 and 203, respectively. A limiting ring 206 is fixedly connected to the outer wall of the connecting rod 204. A circular ring 211 is sleeved on the outer wall of the connecting rod 204. The circular ring 211 is fixedly connected to the through groove 6. A fastening ring 212 is slidably arranged inside the circular ring 211. A stop bar 213 is fixedly connected and passes through a fastening ring 212. A limiting groove 217 is symmetrically opened on both sides of the inner wall of the through groove 6. A limiting rod 208, which is used in conjunction with the limiting ring 206, is slidably installed inside the two limiting grooves 217. A return spring is fixedly connected to the inner bottom surface of the two limiting grooves 217, and the other end of the return spring is fixedly connected to the end of the limiting rod 208. Two grooves 207, which are used in conjunction with the limiting grooves 217, are symmetrically opened on the outer wall of the limiting ring 206. A thread 214 is opened on the inner wall of the circular ring 211, a thread 216 is opened on the outer wall of the stop bar 213, a thread 215 is opened on the outer wall of the fastening ring 212 to be used in conjunction with the thread 214, and a thread 218 is opened on the inner wall of the fastening ring 212 to be used in conjunction with the thread 216.

[0033] The operation process of this embodiment is as follows: When it is not necessary for the object on the support plate 301 to rotate, the rotating stop rod 213 is rotated. The stop rod 213 drives the connecting rod 204 and the limiting ring 206 on the outer surface of the connecting rod 204 to rotate together. Pulling the stop rod 213, the stop rod 213 drives the connecting rod 204, the limiting ring 206 and the rack 5 to move together. During the movement of the connecting rod 204, the conical surface on one side of the limiting ring 206 outside the connecting rod 204 contacts the inclined surface of the limiting rod 208 in the limiting groove 217, pushing the limiting rod 208 to move. At this time, the return spring 1 in the limiting groove 217 is compressed. When the conical surface of the limiting ring 206 disengages from the inclined surface of the limiting rod 208, the elastic potential energy of the return spring 1 in the limiting groove 217 is released, pushing the limiting rod 208 to pop out, so that the plane of the limiting rod 208 is aligned with the limiting ring. One side of the plane of 206 contacts the connecting rod 204, limiting the rack 5 and the second gear 305. At this time, the rack 5 does not contact the second gear 305, and the bearing plate 301 does not rotate. The stop rod 213 is rotated counterclockwise, and the stop rod 213 drives the connecting rod 204 and the limiting ring 206 to rotate. When the groove 207 on the surface of the limiting ring 206 matches the position of the limiting rod 208, the spring 209 outside the circular rod 205 generates elastic potential energy during the movement of the rack 5. At this time, the elastic potential energy is released, pushing the rack 5 to extend and rotate the fastening ring 212. The thread 215 on the outer wall of the fastening ring 212 and the thread 4 on the inner wall are respectively connected to the thread 326 on the outer wall of the stop rod 213 and the thread 124 on the inner wall of the circular ring 211. At this time, the stop rod 213 is fixed, the rack 5 cannot retract, and can then mesh with the second gear 305 to drive the second gear 305 to rotate.
