[0002] The back panel of a TV is usually sprayed on the surface to increase its weather resistance. In the continuous spraying process of the TV back panel, hooks are evenly arranged on the running track. The running track enters the spray room from the entrance of the spray room, passes through the spray equipment, and then extends from the exit to the outside of the spray room. First, the TV back panel is manually hung on the hook. Based on the movement of the running track, the hook carries the TV back panel into the spray room and passes through the spray equipment before being removed from the spray room. The TV back panel is manually removed from the hook, which is labor-intensive.

[0031] Combine the following Figures 1 to 4 , describing a television back panel spray loading and unloading device according to an embodiment of the utility model.

[0032] A device for spraying and loading and unloading of a back panel of a television set, comprising a frame 1, a first positioning mechanism 2, a second positioning mechanism 3, a clamping mechanism 4, a lateral displacement mechanism 5, a hanging and unhanging driving mechanism 7 and a lifting mechanism 8;

[0033] The first positioning mechanism 2 is installed on the frame 1, and the first positioning mechanism 2 and the second positioning mechanism 3 are opposite to each other. The first positioning mechanism 2 and the second positioning mechanism 3 are used to position the hook;

[0034] The lifting mechanism is installed on the frame 1, the lifting mechanism 8 is provided with a lifting seat 81, and the detaching and hanging driving mechanisms are all installed on the lifting seat 81; the lateral displacement mechanism 5 is installed on the detaching and hanging driving mechanism 7, the clamping mechanism 4 is installed on the lateral displacement mechanism 5, and the first positioning mechanism 2 is located above the clamping mechanism 4;

[0035] The clamping mechanism 4 is used to clamp the TV back panel, the lateral displacement mechanism 5 is used to drive the clamping mechanism 4 to move closer to or away from the TV back panel, and the hooking and unhooking driving mechanism 7 is used to drive the clamping mechanism 4 to move longitudinally so that the TV back panel is hung on the hook or detached from the hook.

[0036] In the television back panel spray loading and unloading device provided by the utility model, the first positioning mechanism 2 and the second positioning mechanism 3 are used to position the hook on the running track of the spray line, the clamping mechanism 4 can clamp the television back panel, and the television back panel can be detached from the hook or hung on the hook through a small displacement of the detaching and hanging driving mechanism 7, and the lifting mechanism 8 can carry the clamping mechanism 4 to lower the television back panel from the hook to a lower position to facilitate the television back panel to enter the storage trolley or lift the television back panel from a lower position to close to the hook, thereby achieving automatic loading and unloading of the television back panel, saving manual labor intensity and improving production efficiency to a great extent.

[0037] It can be understood that the TV back panel is reserved with a hanging position corresponding to the hook, so that the hanging position of the TV back panel is raised to above the hook, and then the TV back panel is lowered, and the hook can hook the hanging position; when unloading, the TV back panel rises, and the hanging position of the TV back panel is detached from the hook, so that the TV back panel is away from the hook.

[0038] When the device of the utility model is used for loading, the clamping mechanism 4 clamps the TV back panel, and the lifting mechanism 8 carries the clamping mechanism 4 to raise the TV back panel to close to the hook, and at the same time the first positioning mechanism 2 and the second positioning mechanism 3 position the hook; then, the lateral displacement mechanism 5 moves the clamping mechanism 4 toward the hook until the hanging position of the TV back panel is above the hook, and then, the unhooking drive mechanism 7 causes the clamping mechanism 4 to move downward a small amount, so that the hook hooks the hanging position of the TV back panel; thereafter, the clamping mechanism 4 releases the clamping of the TV back panel, and the lateral displacement mechanism 5 drives the clamping mechanism 4 away from the TV back panel, and then, the lifting mechanism 8 causes the clamping mechanism 4 to descend to load the next TV back panel.

[0039] When the device of the utility model is used for unloading, the first positioning mechanism 2 and the second positioning mechanism 3 position the hook, and at the same time the lifting mechanism 8 carries the clamping mechanism 4 to rise close to the TV back plate, and the lateral displacement mechanism 5 makes the clamping mechanism 4 move toward the TV back plate until the clamping mechanism 4 can clamp the TV back plate, and the clamping mechanism 4 clamps the TV back plate, and then, the unhooking drive mechanism 7 makes the clamping mechanism 4 move upward a small amount, so that the hanging position of the TV back plate is separated from the hook and the hanging position of the TV back plate is above the hook, and the lateral displacement mechanism 5 drives the clamping mechanism 4 to move the TV back plate away from the hook, and then, the lifting mechanism 8 makes the clamping mechanism 4 descend to a low position to facilitate the TV back plate to enter the storage trolley, and then, the lifting mechanism 8 makes the clamping mechanism 4 rise to the next TV back plate on the hook close to the running track, and continues to complete the unloading action.

[0040] In one embodiment of the present invention, the first positioning mechanism 2 and the second positioning mechanism 3 both include a positioning cylinder 31 and a positioning clamping plate 4432. The piston rod of the positioning cylinder 31 is connected to the positioning clamping plate 4432. The two positioning clamping plates 4432 are located opposite to each other.

[0041] The first positioning mechanism 2 or the second positioning mechanism 3 is provided with a position sensor, and both the first positioning mechanism 2 and the second positioning mechanism 3 are electrically connected to the position sensor.

[0042] The position sensor is used to sense whether the hook on the spray running track is in place. When the position sensor senses that the hook is in place, the first positioning mechanism 2 and the second positioning mechanism 3 are both electrically connected to the position sensor. The two positioning mechanisms act simultaneously to complete the clamping of the hook, that is, the piston rods of the positioning cylinders 31 of the first positioning mechanism 2 and the second positioning mechanism 3 extend simultaneously, and the two positioning clamps 4432 move toward each other until the hook is clamped. When the hook is positioned, the position of the TV back panel hanging on it is fixed, which is convenient for the clamping mechanism 4 to clamp the TV back panel.

[0043] In one embodiment of the utility model, the clamping mechanism 4 includes a mounting seat 41, a clamping cylinder 42, a push rocker 43 and a clamping plate 44. The clamping cylinder 42 is arranged on the mounting seat 41, the middle part of the push rocker 43 is rotatably connected to the mounting seat 41, and two clamping plates 44 are arranged on both sides of the mounting seat 41 and slideably cooperate with the mounting seat 41.

[0044] The piston rod of the clamping cylinder 42 is hinged to the pushing swing rod 43 , and both ends of the pushing swing rod 43 are hinged to the clamping plate 44 through connecting rods 45 .

[0045] When the piston rod of the clamping cylinder 42 is extended and retracted, based on the transmission of the swing push rod and the connecting rod 45, the two clamping plates 44 can move toward each other, thereby achieving the effect of clamping the back panel of the TV and loosening the back panel of the TV. The sliding cooperation between the clamping plate 44 and the mounting seat 41 enables the two clamping plates 44 to maintain a relatively parallel positional relationship, thereby achieving a stable clamping effect. Preferably, the clamping plate 44 has a long clamping groove, and the edge of the TV back panel is located in the clamping groove when the clamping mechanism 4 is clamped, so that the clamping groove has a larger opening width so that the edge of the TV back panel can smoothly enter the groove. Further preferably, the inner wall of the clamping groove is covered with a soft rubber pad, which can increase the friction between the clamping plate 44 and the edge of the TV back panel on the one hand, and prevent the TV back panel from being deformed due to clamping on the other hand.

[0046] Preferably, the lateral displacement mechanism 5 includes a first motor 51, a driving gear 52 and a rack 53, wherein the driving gear 52 is arranged at the output end of the first motor 51, and the rack 53 is mounted on the mounting seat 41, and the driving gear 52 is meshed with the rack 53. The lateral displacement mechanism 5 drives the mounting seat 41 to move in the horizontal direction by meshing the gear rack 53, has a large driving speed and sufficient displacement accuracy, and takes up little installation space, so that the structure of the device of this embodiment is relatively compact. It can be understood that by controlling the forward and reverse rotation of the first motor 51, the clamping mechanism 4 is moved close to or away from the hook of the spraying operation track.

[0047] Preferably, the hook-and-unhook drive mechanism 7 includes a second motor 71, a screw rod 72 and a movable seat 73. The second motor 71 is drivingly connected to one end of the screw rod 72, and the movable seat 73 is sleeved on the screw rod 72; the screw rod 72 and the rack 53 are perpendicular to each other. The driving mode of the motor screw rod 72 can make the hook-and-unhook drive mechanism 7 have a high driving accuracy, thereby completing the action of the TV back panel being taken off the hook and being hooked by the hook. Preferably, in order to make the device structure of this embodiment compact, the second motor 71 and the screw rod 72 are adjacent to each other at the installation position of the lifting seat 81, and a driven pulley is installed at the end of the screw rod 72, and a driving pulley is provided at the output end of the second motor 71, and the driving pulley and the driven pulley are sleeved with a synchronous belt. Specifically, the side of the second motor 71 is fixedly connected to the lifting seat 81, and the two ends of the screw rod 72 are rotatably connected to the lifting seat 81 respectively.

[0048] Preferably, the first motor 51 is installed on the side of the moving seat 73 away from the screw rod 72, and a guide assembly 6 is respectively provided between the moving seat 73 and the mounting seat 41 and between the moving seat 73 and the lifting seat 81. The setting of the guide assembly 6 makes the movement of the mounting seat 41 and the moving seat 73 more stable.

[0049] In one embodiment of the utility model, the lifting mechanism includes a third motor 82, a driving pulley 83, a driven pulley 84 and a conveyor belt 85. The output end of the third motor 82 is connected to the driving pulley 83, and the conveyor belt 85 is sleeved on the driving pulley 83 and the driven pulley 84. The driving pulley 83 and the driven pulley 84 are respectively arranged at the upper and lower ends of the frame 1, and the lifting seat 81 is fixedly connected to the conveyor belt 85. By driving the lifting seat 81 to rise and fall by belt transmission, a higher operating speed can be achieved, thereby achieving a fast loading and unloading speed, which is conducive to improving the efficiency of the spraying line.
