Abstract
Description
A TV back cover handling and assembly mechanism Technical Field
[0001] This utility model belongs to the field of TV back cover assembly technology, specifically relating to a TV back cover handling and assembly mechanism. Background Technology
[0002] Liquid crystal displays (LCDs) are widely used in people's lives due to their lightweight, low power consumption, and low radiation. As people's requirements for the appearance of LCD devices continue to increase, LCD devices also need to be manufactured to be thinner and thinner. Existing module structures, including a plastic back cover, a TV back panel, and components such as fixing structures, LEDs, reflective sheets, light guide plates, and films, suffer from low success rates when assembling the back cover and back panel due to the curved and uneven surface of the back cover. After material handling, the back cover and back panel do not fit properly, leading to product defects. Furthermore, traditional material handling devices lack curved surface pressing structures; after the TV back cover is handled, it can only be pressed flatly at the TV back panel, while curved surface pressing requires subsequent processes. This method is not only time-consuming and labor-intensive but also affects the efficiency of TV back panel assembly. Summary of the Invention
[0003] The purpose of this invention is to provide a TV back cover handling and assembly mechanism, which aims to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a TV back cover handling and assembly mechanism, comprising: a mounting plate, wherein a connector for connecting to a robotic arm is mounted at the top center of the mounting plate;
[0005] A front pressing mechanism, wherein the front pressing structure is mounted on one side of the mounting plate;
[0006] A curved surface pressing mechanism is installed at the tail end of the mounting plate. Both the front pressing mechanism and the curved surface pressing mechanism are used to press the TV back cover onto the TV.
[0007] The material handling assembly is installed at the bottom of the mounting plate. The material handling assembly includes a vacuum sponge suction cup. Four guide rods are installed at the top of the vacuum sponge suction cup. Guide sleeves are installed at the four corners of the mounting plate. The guide rods are inserted into the guide sleeves.

The two ends of the springs are connected to the mounting plate and the vacuum sponge suction cup, respectively.
[0008] As a preferred technical solution of this utility model, the front pressing mechanism includes a first connecting plate installed on one side of the mounting plate. The surface of the first connecting plate has multiple sets of through first strip-shaped adjustment grooves, with two in each set. The first connecting plate is provided with a first pressing cylinder at the bottom of each set of first strip-shaped adjustment grooves. A pressing head is installed on the telescopic end of the first pressing cylinder. Two first screw holes are symmetrically opened on the fixed end of the first pressing cylinder. Two first fixing bolts are inserted in each set of first strip-shaped adjustment grooves, and the first fixing bolts are threadedly connected to the corresponding first screw holes.
[0009] As a preferred technical solution of this utility model, the curved surface pressing mechanism includes a crossbeam installed at the tail end of the mounting plate. The surface of the crossbeam is provided with two through second strip-shaped adjustment grooves. The bottom of the crossbeam is provided with a plurality of second pressing cylinders.

[0013] In a preferred embodiment of this invention, both the pressing head and the pressing strip are made of rubber.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This assembly mechanism uses a vacuum sponge suction cup. When using the vacuum sponge suction cup to pick up the TV back cover, the vacuum sponge suction cup can effectively accommodate the unevenness of the back cover, thereby improving the success rate of picking up the material. After picking up the material, a robotic arm is used to transport the TV back cover to the TV back panel and press it firmly onto the TV back panel. During this process, the spring can buffer the bonding force to avoid excessive pressing and damage to the back cover and back panel.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please refer to Figures 1-5. The present invention provides the following technical solution: a TV back shell handling and assembly mechanism, including a mounting plate 1, a front pressing mechanism 3, a curved pressing mechanism 4 and a material picking component 5. A connector 2 connected to a robotic arm is installed at the top center of the mounting plate 1.
[0024] The front-side pressing structure is installed on one side of the mounting plate 1;
[0025] The curved surface pressing mechanism 4 is installed at the tail end of the mounting plate 1. Both the front pressing mechanism 3 and the curved surface pressing mechanism 4 are used to press the TV back cover onto the TV.
[0026] In this embodiment, the material picking component 5 is installed at the bottom of the mounting plate 1. The material picking component 5 includes a vacuum sponge suction cup 51. Four guide rods 52 are installed at the top of the vacuum sponge suction cup 51. Guide sleeves 53 are installed at the four corners of the mounting plate 1. The guide rods 52 are inserted into the guide sleeves 53. Limiting blocks 54 are installed at the top of the guide rods 52. Springs 55 are sleeved on the outside of the guide rods 52. The two ends of the springs 55 are connected to the mounting plate 1 and the vacuum sponge suction cup 51, respectively.
[0027] Specifically, the assembly mechanism is connected to the robotic arm using connector 2. The robotic arm moves the assembly mechanism to the TV back cover and uses the vacuum sponge suction cup 51 to pick up the TV back cover. During this process, the vacuum sponge suction cup 51 squeezes the spring 55, thereby generating compression through the spring 55 to buffer the force on the back cover during material picking, thus avoiding damage to the back cover. The vacuum sponge suction cup 51 can effectively accommodate the unevenness of the back cover surface, thereby improving the success rate of material picking. Afterwards, the robotic arm transports the back cover to the back panel and places it on the back panel. During this process, the compression generated by the spring 55 also buffers the force when the back cover and the back panel are attached, avoiding damage to the back cover and the back panel, thereby improving the yield rate.
[0028] In this embodiment, the front pressing mechanism 3 includes a first connecting plate 31 installed on one side of the mounting plate 1. The surface of the first connecting plate 31 has multiple sets of through first strip-shaped adjustment grooves 32, with two grooves in each set. The first connecting plate 31 is provided with a first pressing cylinder 33 at the bottom of each set of first strip-shaped adjustment grooves 32. A pressing head 34 is installed on the telescopic end of the first pressing cylinder 33. Two first screw holes 35 are symmetrically opened on the fixed end of the first pressing cylinder 33. Two first fixing bolts 36 are inserted in each set of first strip-shaped adjustment grooves 32, and the first fixing bolts 36 are threadedly connected to the corresponding first screw holes 35.
[0029] Specifically, the installation position of the first pressing cylinder 33 is adjustable by using the first strip-shaped adjustment groove 32 in conjunction with the first fixing bolt 36. The operator can adjust the installation position of the first pressing cylinder 33 according to the size of the back shell of different specifications, so that the first pressing cylinder 33 can be used for the assembly and pressing of back shells of different specifications and sizes. The first pressing cylinder 33 drives the pressing head 34 to press down, which can complete the pressing assembly between the front of the back shell and the back plate.
[0030] In this embodiment, the curved surface pressing mechanism 4 includes a crossbeam 41 installed at the tail end of the mounting plate 1. The surface of the crossbeam 41 is provided with two through second strip-shaped adjustment grooves 42. The bottom of the crossbeam 41 is provided with a plurality of second pressing cylinders 43. The telescopic end of the second pressing cylinder 43 is provided with a second connecting plate 44. The bottom end of the second connecting plate 44 is provided with a pressing strip 45. The fixed end of the second pressing cylinder 43 is provided with two second screw holes 46. The second screw holes 46 are internally threaded with second fixing bolts 47. The second fixing bolts 47 pass through the second strip-shaped adjustment grooves 42 and are connected to the second screw holes 46.
[0031] Specifically, the installation position of the second pressing cylinder 43 can be adjusted by using the second strip-shaped adjustment groove 42 in conjunction with the second fixing bolt 47. The operator can adjust the installation position of the second pressing cylinder 43 according to the size of the back shell of different specifications, so that the second pressing cylinder 43 can be used for assembly and pressing of the curved surface of the back shell of different specifications and sizes. The second pressing cylinder 43 drives the second connecting plate 44 to descend, so that the pressing strip 45 can press and assemble the curved surface of the back shell with the back plate. In this way, the conveying mechanism can realize the material handling and front pressing of the back shell and the back pressing, effectively improving the assembly efficiency of the TV back shell.
[0032] In this embodiment, a slotted photoelectric switch 6 is mounted on the front of the mounting plate 1, and a sensing plate 7 is mounted on the top of one of the limiting blocks 54. The sensing plate 7 is located directly below the slotted photoelectric switch 6.
[0033] Specifically, when the back shell is being picked up and assembled, the vacuum sponge suction cup 51 will squeeze the spring 55. At this time, the guide rod 52 will rise inside the guide sleeve 53. When the slotted photoelectric switch 6 detects the sensing plate 7, the robotic arm stops pressing down. In this way, the downward pressure of the robotic arm can be limited and protected, thereby improving the yield rate.
[0034] In this embodiment, the head diameter of the first fixing bolt 36 is greater than the width of the first strip-shaped adjustment groove 32, and the head diameter of the second fixing bolt 47 is greater than the width of the second strip-shaped adjustment groove 42.
[0035] Specifically, this method enables the first pressing cylinder 33 and the second pressing cylinder 43 to be fixed to the first connecting plate 31 and the crossbeam 41 respectively when the first fixing bolt 36 and the second fixing bolt 47 are tightened.
[0036] In this embodiment, the number of first pressing cylinders 33 includes, but is not limited to, four, and the number of second pressing cylinders 43 includes, but is not limited to, two.
[0037] In this embodiment, both the pressing head 34 and the pressing strip 45 are made of rubber.
[0038] Specifically, this method ensures that the pressing head 34 and pressing strip 45 do not damage the surface of the TV back cover during the pressing and assembly process, thereby improving the yield rate.
[0039] It is worth noting that in this application, the first pressing cylinder 33, the second pressing cylinder 43, the vacuum sponge suction cup 51, the slotted photoelectric switch 6, and the sensing plate 7 are all connected to an external PLC controller, and the external robotic arm is also connected to the PLC controller. The automated operation of this assembly mechanism is realized through the PLC controller.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
