Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a turning device of a television backboard according to an embodiment of the utility model. The embodiment of the utility model provides a turnover device of a television backboard, which comprises a conveying line 21, a first driving part 22, a first adsorption part 23, a second driving part 24 and a second adsorption part 25.

The conveying line 21 is used for conveying the television backboard 100, so that the television backboard 100 is prevented from being contacted with the television backboard 100 in the process of manually conveying the television backboard 100, and further, the television backboard 100 is prevented from being stained in the process of conveying.

The first driving member 22 is provided to the conveying line 21. The first adsorption member 23 is used for adsorbing the back surface of the television back plate 100 conveyed by the conveying line 21. The first adsorption component 23 is in transmission connection with the first driving component 22, so that the first adsorption component 23 can be driven by the first driving component 22 to lift the television backboard 100.

The second driving member 24 is provided to the conveying line 21. The second adsorption component 25 is used for adsorbing the back surface of the television backboard 100 conveyed by the conveying line 21, and the second adsorption component 25 is in transmission connection with the second driving component 24, so that the second adsorption component 25 can be driven by the second driving component 24 to lift the television backboard 100.

Wherein the highest point of the first adsorption member 23 moved by the first driving member 22 is located at the first height, or the highest point of the stroke of the first adsorption member 23 is located at the first height. The highest point of the second adsorbing member 25 moved by the second driving member 24 is located at the second height, or the highest point of the stroke of the second adsorbing member 25 is located at the second height. At this time, the first height is greater than the second height.

Therefore, when the first adsorption member 23 and the second adsorption member 25 are both located at the highest point of the respective strokes, a height difference can be formed between the first adsorption member 23 and the second adsorption member 25, and the television back plate 100 lifted by the first adsorption member 23 and the second adsorption member 25 is fixed in an inclined manner with the back surface facing downward.

It can be further understood that, taking the back of the television backboard 100 as an example, the back is conveyed in a vertically downward posture, if the automatic rotating arm is used to drive the television backboard 100 to rotate, when the rotating angle of the rotating arm is wrong, the turning angle of the television backboard 100 may exceed 90 °, so that the television backboard 100 presents a posture with the inner surface facing downward, and the optical film in the television backboard 100 is caused to drop. In contrast, in the embodiment of the present utility model, the first adsorption member 23 and the second adsorption member 25 are matched, which are higher and lower, so that the turnover angle of the television back plate 100 can be effectively limited to be less than 90 degrees, and the optical film in the television back plate 100 is prevented from falling off.

With continued reference to fig. 2, fig. 2 is a schematic structural diagram of the flipping device shown in fig. 1 at another view angle. In some embodiments, the tilt angle of the television back plate 100 may be greater than or equal to 40 degrees and less than or equal to 65 degrees when the first adsorption member 23 is moved to the first height and the second adsorption member 25 is moved to the second height. Therefore, the television backboard 100 or the optical film therein can be prevented from sliding down due to the overlarge inclination angle of the television backboard 100; and it is possible to avoid too small an inclination angle of the television back plate 100, which may cause an operator or an automation device to be inconvenient to screw from the back of the television back plate 100 to fix the television center.

Illustratively, the first and second adsorbent members 23, 25 move in the same direction. The first adsorbing member 23 and the second adsorbing member 25 have a distance L, and the first height and the second height have a height difference H. Where α=arctan (H/L), α is greater than or equal to 40 degrees and less than or equal to 65 degrees, so that the inclination angle of the television back plate 100 may be greater than or equal to 40 degrees and less than or equal to 65 degrees.

For example, α may be 40 degrees, 43 degrees, 44.5 degrees, 45 degrees, 47 degrees, 49 degrees, 50 degrees, 51 degrees, 53 degrees, 54 degrees, 55.3 degrees, 56.1 degrees, 58 degrees, 59.7 degrees, 60.8 degrees, 61.5 degrees, 63 degrees, 64.7 degrees, 65 degrees, which the embodiments of the present utility model are not limited to.

Of course, in some other embodiments, α may be greater than or equal to 45 degrees and less than or equal to 60 degrees, which is not limited by the present embodiment. Alternatively, α is less than 40 degrees or greater than 65 degrees, which is not limited in this regard by the embodiments of the present utility model.

In some other embodiments, the number of first driving members 22 and first adsorbing members 23 is at least two, and each first driving member 22 is in driving connection with at least one first adsorbing member 23. Therefore, the first driving component 22 and the first adsorption component 23 which are connected through multiple groups of transmission can jointly adsorb the television backboard 100 from multiple positions of the television backboard 100, so that the turnover device 200 is more stable when lifting the television backboard 100, and the risk of falling of the television backboard 100 is avoided.

Wherein, each first driving part 22 is in transmission connection with at least one first adsorption part 23, and each first driving part 22 can be in transmission connection with one first adsorption part 23; such as the number of first driving parts 22 being two, the number of first adsorbing parts 23 being also two, the two first driving parts 22 and the two first adsorbing parts 23 being in one-to-one correspondence.

Optionally, each first driving part 22 is in driving connection with at least one first adsorption part 23, and it is also possible that each first driving part 22 is in driving connection with at least two first adsorption parts 23. For example, the number of the first driving parts 22 is two, the number of the first adsorption parts 23 is four, and each first driving part 22 is respectively in transmission connection with two first adsorption parts 23, so that each first driving part 22 can drive two first adsorption parts 23 to move, which is not limited in the embodiment of the present utility model.

Of course, in some other embodiments, the number of the first driving parts 22 and the first adsorbing parts 23 may be one, which is not limited by the embodiment of the present utility model.

In some embodiments, the number of second driving members 24 and second adsorbing members 25 is at least two, and each second driving member 24 is in driving connection with at least one second adsorbing member 25. Therefore, the second driving component 24 and the second adsorption component 25 which are connected through multiple groups of transmission can jointly adsorb the television backboard 100 from multiple positions of the television backboard 100, so that the turnover device 200 is more stable when lifting the television backboard 100, and the risk of dropping the television backboard 100 is avoided.

Wherein, each second driving part 24 is in transmission connection with at least one second adsorption part 25, and each second driving part 24 can be in transmission connection with one second adsorption part 25; such as two second driving parts 24, and two second adsorbing parts 25, the two second driving parts 24 and the two second adsorbing parts 25 are in one-to-one correspondence.

Optionally, each second driving member 24 is in driving connection with at least one second adsorbing member 25, and it is also possible that each second driving member 24 is in driving connection with at least two second adsorbing members 25. For example, the number of the second driving parts 24 is two, the number of the second adsorption parts 25 is four, and each second driving part 24 is in transmission connection with two second adsorption parts 25, so that each second driving part 24 can drive two second adsorption parts 25 to move, which is not limited in the embodiment of the present utility model.

Of course, in some other embodiments, the number of the second driving parts 24 and the second adsorbing parts 25 may be one, which is not limited by the embodiment of the present utility model.

When the number of the first adsorbing members 23 and the second adsorbing members 25 is at least two, all the first driving members 22 are arranged in the conveying direction of the conveying line 21, all the second driving members 24 are arranged in the conveying direction of the conveying line 21, the first driving members 22 are located at one side of the second driving members 24 in the first direction, and the first direction is perpendicular to the conveying direction of the conveying line 21.

For example, the conveying direction of the conveying line 21 may be a left-right direction, or the conveying line 21 conveys the television back panel 100 from left to right, so that all the first adsorption members 23 are arranged in a row along the left-right direction, and all the second adsorption members 25 are also arranged in a row along the left-right direction. In this case, the first adsorption member 23 may be disposed on the front side and the second adsorption member 25 may be disposed on the rear side, or the first adsorption member 23 may be disposed on the rear side and the second adsorption member 25 may be disposed on the front and rear sides.

In some embodiments, the conveyor line 21 comprises a roller conveyor line with an avoidance gap 211 formed between adjacent rollers of the roller conveyor line.

The first driving component 22 and the first adsorption component 23 are both located at the lower side of the conveying plane of the conveying line 21, and the first adsorption component 23 is opposite to the avoidance gap 211, so that the first adsorption component 23 can pass through the avoidance gap 211 under the driving of the first driving component 22, thereby lifting the television backboard 100.

The second driving part 24 and the second adsorption part 25 are both positioned at the lower side of the conveying plane of the conveying line 21, and the second adsorption part 25 is arranged opposite to the avoidance gap 211, so that the first adsorption part 23 can pass through the avoidance gap 211 under the driving of the first driving part 22, thereby lifting the television backboard 100.

With continued reference to fig. 3, fig. 3 is a schematic structural diagram of the turning device shown in fig. 1 after the conveyor line is removed. In some embodiments, the turning device 200 further includes a positioning assembly 26, where the positioning assembly 26 is mounted on the conveying line 21, and the positioning assembly 26 is used for positioning the television backboard 100 conveyed by the conveying line 21. And the positioning assembly 26 can accurately position the television backboard 100 on the conveying line 21, so that the first adsorption component 23 and the second adsorption component 25 can adsorb the television backboard 100 from the ideal adsorption position of the television backboard 100, and the first adsorption component 23 and the second adsorption component 25 can accurately and firmly adsorb the television backboard 100.

For example, the positioning assembly 26 may include a third drive member 261 and a stop 262. A third driving part 261 such as a cylinder, an electric push rod, a hydraulic cylinder, an oil cylinder, or a linear die set is provided to the conveyance line 21. The third driving part 261 is located at the lower side of the conveying plane of the conveying line 21. The blocking element 262 is in driving connection with the third drive part 261. The blocking member 262 is located at the lower side of the conveying plane of the conveying line 21, and the blocking member 262 is opposite to the escape gap 211, so that the blocking member 262 can pass through the escape gap 211 by being driven by the third driving part 261, thereby positioning the television back plate 100 conveyed by the conveying line 21.

For example, when the television back plate 100 needs to be positioned, the third driving member 261 can drive the blocking member 262 to extend to the upper side of the conveying plane, so as to limit the television back plate 100 on the conveying line 21 to move continuously, and further position the television back plate 100 on the conveying line 21. After the television back plate 100 has been locked to the television center, the third drive member 261 can drive the stop 262 to retract to the underside of the conveying plane so that the television back plate 100 on the conveyor line 21 can continue to move.

In some embodiments, the turning device 200 further includes a carrier 27, where the carrier 27 is supported on the conveying line 21, so that the conveying line 21 can convey the carrier 27. The carrier 27 is used for carrying the television backboard 100, so that the support of the television backboard 100 by the carrier 27 can enable the conveying line 21 to convey the television backboard 100 more accurately and stably. The carrier 27 may be provided with a first through hole 271 and a second through hole 272 to enable the first adsorption member 23 to pass through the first through hole 271 to lift the television back plate 100 carried by the carrier 27, and to enable the second adsorption member 25 to pass through the second through hole 272 to lift the television back plate 100 carried by the carrier 27.

Then, a workflow of an embodiment of the present utility model may be as follows:

in the first step, the first driving part 22, the first adsorbing part 23, the second driving part 24 and the second adsorbing part 25 are all positioned at the lower side of the conveying plane of the conveying line 21, and the third driving part 261 drives the blocking member 262 to extend to the upper side of the conveying plane of the conveying line 21.

In a second step, the conveyor line 21 conveys the carriers 27 carrying the television back plate 100 until the carriers 27 are blocked by the blocking member 262.

Third, the first driving part 22 drives the first adsorption part 23 to sequentially pass through the avoidance gap 211 and the first through hole 271, and then adsorbs the back surface of the television backboard 100, and supports the television backboard 100; meanwhile, the second driving part 24 drives the second adsorption part 25 to sequentially pass through the avoidance gap 211 and the second through hole 272 and then adsorb the back plate of the television back plate 100, and hold up the televisions respectively; until the first adsorption member 23 is moved to the first height, the second adsorption member 25 is moved to the second height.

Fourth, the operator screws the television center from the back of the television back plate 100.

Fifth, the first driving part 22 and the first adsorption part 23 are reset, and the second driving part 24 and the second adsorption part 25 are reset, so that the television backboard 100 locked with the television middle frame is supported on the carrier 27 again.

Sixth, the third driving part 261 and the blocking part 262 are reset, so that the conveyor line 21 can continue to convey away the carrier 27 and the television backboard 100 supported by the carrier 27.

Of course, in some embodiments, the flipping device 200 may further include a first sensor (not shown in the figures) for detecting the position information of the carrier 27. Furthermore, the first sensor can avoid that the first adsorption member 23 cannot pass through the first through hole 271 and/or the second adsorption member 25 cannot pass through the second through hole 272 when the position of the carrier 27 is wrong, and the carrier 27 is overturned.

In some embodiments, the first suction member 23 may include a first suction nozzle. The second suction member 25 may include a second suction nozzle. Furthermore, the first suction nozzle and the second suction nozzle can perform suction fixation on the television backboard 100 through a vacuum suction manner.

In some embodiments, the first drive member 22 may include a first cylinder. A piston rod of the first air cylinder is rotationally connected with the first suction nozzle. Thus, in the process of turning over the television backboard 100, the first suction nozzle can be adaptively rotated to more stably and reliably suck the television backboard 100.

For example, the turning device 200 may further include a first rotary connection assembly 28, where the first rotary connection assembly 28 includes a first rotary member and a second rotary member that are rotatably connected, the first rotary member is fixedly connected to a piston rod of the first cylinder, and the second rotary member is fixedly connected to the first suction nozzle.

In some embodiments, the first cylinder may be detachably connected. Further, the first cylinder having a different stroke may be replaced to adjust the inclination angle of the tv backplate 100.

Of course, in some other embodiments, the first driving component 22 may be an electric push rod, a hydraulic cylinder, an oil cylinder, a linear module, and the like, which is not limited by the embodiment of the present utility model.

In some embodiments, the second driving part 24 comprises a second air cylinder, the piston rod of which is in rotational connection with the second suction nozzle. Thus, during the process of turning over the television back plate 100, the second suction nozzle can be adaptively rotated to more stably and reliably suck the television back plate 100.

For example, the turning device 200 may further include a second rotating connection assembly 29, where the second rotating connection assembly 29 includes a third rotating member and a fourth rotating member that are rotatably connected, the third rotating member is fixedly connected to a piston rod of the second cylinder, and the fourth rotating member is fixedly connected to the second suction nozzle.

In some embodiments, the second cylinder may be detachably connected. Further, the second cylinder having a different stroke may be replaced to adjust the inclination angle of the tv backplate 100.
