[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a large-size television assembly and conveying device. The large-size television assembly and conveying device includes a conveying mechanism 100, a lifting and transmission mechanism 200, and a dust removal mechanism 300. The conveying mechanism 100 and the lifting and transmission mechanism 200 can return the soft pads required during the assembly of the large-size television to the starting point, and the dust removal mechanism 300 can clean the floating dust on the surface of the soft pads.

[0030] Specifically, the conveying mechanism 100 includes a fixed frame 101, a roller 102, a conveyor belt 103, a first motor 104, and a vertical plate 105. The roller 102 is rotatably connected to the surface of the fixed frame 101, the conveyor belt 103 is sleeved on the surface of the roller 102, the first motor 104 is fixedly connected to the surface of the fixed frame 101, the shaft of the first motor 104 is fixedly connected to one end of the roller 102, and the vertical plate 105 is fixedly connected to the surface of the fixed frame 101.

[0031] There are several rollers 102, which are rotatably connected to the surfaces of two opposing fixed frames 101 via bearings. The side rollers 102 and the conveyor belt 103 play a conveying role, while the other rollers 102 provide support and a certain conveying function, and can rotate to reduce obstruction. The upper and lower vertical plates 105 are connected by vertical plates 105, which also play a supporting role. There are two first motors 104, which drive the two conveyor belts 103 to convey different materials.

[0032] Specifically, the lifting and transmission mechanism 200 is installed on the surface of the fixed frame 101 and includes a lifting component 201, a transmission component 202 and a guardrail 203. The transmission component 202 is disposed on the surface of the lifting component 201, the lifting component 201 is located on one side of the conveyor belt 103, and the guardrail 203 is sleeved on the surfaces of the transmission component 202 and the lifting component 201.

[0033] The lifting component 201 can lift the conveyor component 202, thereby lifting the soft pad on the conveyor component 202. The soft pad that has moved onto the conveyor component 202 can be transferred to the upper conveyor belt 103 and the lower conveyor belt 103.

[0034] Specifically, the dust removal mechanism 300 is installed on the surface of the vertical plate 105 and includes an impact component 301 and a dust suction component 302. The impact component 301 is disposed on the surface of the roller 102 and the vertical plate 105, and the dust suction component 302 is disposed on the surface of the vertical plate 105.

[0035] Driven by the lower roller 102, the striking element 301 can strike the soft pads on the lower conveyor belt 103 that are being transported from the conveyor 202, causing the floating dust to rise and then be collected by the dust collection element 302.

[0036] Example 2

[0037] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the lifting component 201 includes a lower shell 201a, an upper shell 201b, a cross lifting frame 201c, a first guide hole 201d, and a second guide hole 201e. The first guide hole 201d is formed on the surface of the lower shell 201a, and the second guide hole 201e is formed on the surface of the upper shell 201b. The cross lifting frame 201c is rotatably connected to the surfaces of the lower shell 201a and the upper shell 201b, and the ends of the cross lifting frame 201c are slidably connected in the first guide hole 201d and the second guide hole 201e.

[0039] The first guide hole 201d and the second guide hole 201e allow one end of the cross lifting frame 201c to be unobstructed when it is unfolded and closed, enabling it to rotate and lift normally. The end of the cross lifting frame 201c that is rotatably connected to the lower shell 201a and the upper shell 201b will not change. The end of the cross lifting frame 201c that is slidably connected in the first guide hole 201d and the second guide hole 201e can move within them.

[0040] A cylinder 201f is fixedly connected to the surface of the lower shell 201a, and a connecting block 201g is fixedly connected to the output end of the cylinder 201f. The connecting block 201g is sleeved on the surface of the cross lifting frame 201c.

[0041] The connecting block 201g indirectly connects the cylinder 201f and the cross lifting frame 201c. When the cylinder 201f extends or retracts, it can drive the connecting block 201g to move, thereby acting on the cross lifting frame 201c to close or unfold, and causing the upper shell 201b to move down or up.

[0042] The transmission component 202 includes a fixed plate 202a, a rotating rod 202b, and a synchronous disk 202c. The fixed plate 202a is fixedly connected to the top of the upper shell 201b, the rotating rod 202b is rotatably connected to the surface of the fixed plate 202a, and the synchronous disk 202c is sleeved on the surface of the rotating rod 202b.

[0043] There are several rotating rods 202b, which are rotatably connected to the surface of the fixed plate 202a via bearings. The fixed plate 202a provides position and support for the installation of the rotating rods 202b. The synchronous disc 202c is fixedly connected to the rotating rods 202b. When the rotating rods 202b rotate, they can drive the synchronous discs 202c to rotate. The synchronous discs 202c and synchronous belt 202d on the side play a transmission role, while the other synchronous discs 202c play a supporting and certain transmission roles.

[0044] A timing belt 202d is fitted onto the surface of the timing disc 202c. A second motor 202e is fixedly connected to the top of the upper shell 201b. The shaft of the second motor 202e is fixedly connected to one end of the rotating rod 202b.

[0045] The second motor 202e drives the rotating rod 202b connected to it to rotate, which in turn causes the synchronous disc 202c and synchronous belt 202d on it to rotate.

[0046] The striking component 301 includes a support plate 301a, a vertical rod 301b, a roller 301c, a connecting plate 301d, a roller 301e, and a cam 301f. The support plate 301a is fixedly connected to the surface of the vertical plate 105, the vertical rod 301b is slidably connected to the surface of the support plate 301a, the roller 301c is rotatably connected to the lower end of the vertical rod 301b, the connecting plate 301d is fixedly connected to the upper end of the vertical rod 301b, the roller 301e is rotatably connected to both ends of the connecting plate 301d, and the cam 301f is fixedly connected to the end of the roller 102.

[0047] The support plate 301a is fixedly connected to the two vertical plates 105 on opposite sides at both ends. There are two vertical rods 301b, which pass through the support plate 301a. The roller 301c is rotatably connected to the lower end of the two vertical rods 301b through bearings. During the up and down movement of the roller 301c, it can strike the surface of the soft pad, while increasing the force between the soft pad and the conveyor belt 103 and reducing the probability of slippage during conveying. The upper ends of the two vertical rods 301b are fixedly connected to the surface of the connecting plate 301d. When the connecting plate 301d moves up and down, it can drive the two vertical rods 301b to move up and down. The friction between the cam 301f and the roller 301e is reduced by the roller 301e, so that when the cam 301f rotates, it can drive the roller 301e to move up and down, thereby driving the connecting plate 301d to move up and down.

[0048] A spring 301g is fitted on the upper end of the vertical rod 301b. The two ends of the spring 301g are fixedly connected to the surface of the support plate 301a and the surface of the connecting plate 301d, respectively. The connecting plate 301d is slidably connected to the surface of the vertical plate 105.

[0049] When the connecting plate 301d moves upward, the spring 301g is stretched, and under the action of its elastic tension, the connecting plate 301d has the power to return downward. When the protruding part of the cam 301f is not in contact with the roller 301e, the connecting plate 301d, the vertical rod 301b and the roller 301c move downward under the action of the spring 301g, and the soft pad surface is struck in sequence.

[0050] The vacuum cleaner 302 includes a housing 302a, a filter plate 302b, a fan 302c, a connecting pipe 302d, and a short pipe 302e. The housing 302a is fixedly connected to the surface of the vertical plate 105, the filter plate 302b is inserted into the surface of the housing 302a, the fan 302c is fixedly connected to the surface of the housing 302a, the connecting pipe 302d is connected to the top of the housing 302a, and the short pipe 302e is fixedly connected to the surface of the connecting pipe 302d.

[0051] The air entering the chamber 302a is filtered by the filter plate 302b, and dust is trapped inside the chamber 302a. The number of short pipes 302e is several to increase the air intake range. The dust generated at the impact point is transported into the chamber 302a through the short pipes 302e and the connecting pipe 302d by the rotation of the fan blades 302c.

[0052] The end of the short pipe 302e is connected to the suction hood 302f, which is fixedly connected to the surface of the vertical plate 105. The box body 302a is rotatably connected to the surface of the box door, and the filter screen plate 302b is fixedly connected to the surface of the box body 302a. The mounting plate is movably connected to the surface of the box body 302a.

[0053] The suction range is increased by the suction hood 302f. The door is connected to the box body 302a by a hinge, which makes it easy to open and remove the dust collected inside the box body 302a. The mounting plate is magnetically attached to the surface of the box body 302a, which makes it easy to pull out the filter screen 302b for cleaning.

[0054] A fixing block 204 is fixedly connected to the surface of the guardrail 203, and the fixing block 204 is fixedly connected to the surface of the fixing frame 101.

[0055] The guardrail 203 and the fixing frame 101 are indirectly connected by the fixing block 204, which effectively prevents them from shifting during use.

[0056] In use, after the TV assembly is completed and the TV is moved away, the first motor 104 and the two second motors 202e are reversed. The operation of the first motor 104 causes the upper roller 102 and conveyor belt 103 to rotate, conveying the soft pad required for assembly to the end-point transmission component 202. At the same time, the operation of the second motor 202e causes the rotating rod 202b, the synchronous disc 202c and the synchronous belt 202d to rotate, conveying the soft pad to the end-point synchronous belt 202d. The operation of the other transmission component 202 at the starting point conveys the soft pad on it to the surface of the conveyor belt 103 for use.

[0057] Then, the two second motors 202e and the upper first motor 104 are closed, and the two cylinders 201f are extended, causing the cross lifting frame 201c to close, causing the two upper shells 201b and the transmission component 202 to descend. After the descent is completed, the shaft of the lower first motor 104 and the two second motors 202e are rotated forward. The transmission component 202 at the end point transfers the soft pad to the lower conveyor belt 103, and the soft pad on the lower conveyor belt 103 is transferred to the transmission component 202 at the starting point. During the operation of the lower second motor 202e, the roller 102 and the conveyor belt 103 are rotated, causing the cam 301f to rotate. With the cooperation of the spring 301g, the roller 301e, the connecting plate 301d, the vertical rod 301b and the drum 301c move up and down.

[0058] Simultaneously, the operation of fan 302c is controlled, and the up-and-down movement of roller 301c strikes the soft pad on the conveyor belt 103, causing floating dust to rise. Fan 302c transports dust and gas through suction hood 302f, short pipe 302e, and connecting pipe 302d into housing 302a. Filter plate 302b filters the gas entering housing 302a, trapping dust inside, while the gas is discharged. After the conveying is completed, the first motor 104 and two second motors 202e are shut down, and the cylinder 201f retracts, causing the two transmission components 202 to move upward, and the soft pad on the starting transmission component 202 to move upward, replenishing it in time, and repeating the cycle.

[0059] In summary, the conveying mechanism 100 and the lifting and transmission mechanism 200 can return the soft pads required for the assembly of large-size TVs to the starting point, and the dust removal mechanism 300 can clean the floating dust on the surface of the soft pads. Compared with the existing technology, it is not necessary to manually return the soft pads to the starting point of assembly, which reduces the workload and improves the assembly efficiency, effectively avoids a large amount of dust adhering to the surface of the TV, and reduces the difficulty of dust removal after the TV is assembled.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
