Description

Technical Field

[0001] The utility model relates to the field of display technology, in particular to a steering structure and a light board transmission device. Background Art

[0002] During the production process of MLED (Micro LED & Mini LED) direct display screens, light boards carrying Micro LED or Mini LED often need to be transmitted and even changed in different directions for transmission. For example, the light boards were previously transmitted uniformly to the right, but due to space limitations and other factors, after reaching a certain position, the batch of light boards needs to adjust their direction for transmission forward or left.

[0003] Currently, a rotary cylinder is usually used to drive a bunch of mechanisms and products to rotate together to achieve the change of transmission direction. However, because the mechanism parts are heavy, the rotary cylinder is often under high load movement, the life and stability of the rotary cylinder are reduced, which leads to low production efficiency and reduced production quality. Utility Model Content

[0004] The utility model aims to provide a steering structure and a light board transmission device, so as to realize the direction change of the light board quickly and conveniently.

[0005] The utility model is achieved in this way:

[0008] Furthermore, the movable block includes a first surface and a second surface whose height is lower than that of the first surface, the first surface and the second surface are connected via an inclined surface, and the inclined angle of the inclined surface relative to the horizontal plane is 15°-25°.

[0012] Furthermore, the steering structure is arranged in the steering channel, and the width of the lifting platform is smaller than the width of the steering channel.

[0013] By setting the width of the lifting platform to be smaller than the width of the steering channel, the steering structure can be placed in the steering channel, and the steering of the light panel can be achieved by lifting and lowering the lifting platform.

[0015] By setting a stop block and a laser sensor at the edge of the lifting channel, when the light board enters the lifting channel and contacts the stop block, the laser sensor can sense the light board and transmit signals in time to control the descent of the lifting platform to achieve steering operation.

[0016] In a second aspect, the present invention further provides a light board transmission device, the light board transmission device at least comprising a main channel, a turning channel, a turning structure and a controller, the controller is used to control the operation of the main channel, the turning channel and the turning structure; the main channel is used to transmit the light board; the turning channel is arranged at the end of the main channel, and the turning structure is arranged in the turning channel, the turning structure is used to receive the light board transmitted from the main channel, and transfer the light board to the turning channel, so that the light board continues to be transmitted on the turning channel in different directions; The steering structure includes: a lifting mechanism, the lifting mechanism includes a lifting channel and a lifting platform, the lifting channel is fixed to one side of the lifting platform and is connected to the main channel to receive the lamp board transmitted from the main channel; a ball bearing is also provided on the side of the lifting platform away from the lifting channel; an adjusting mechanism, the adjusting mechanism includes a cylinder and a movable block with a height difference on the surface, the top rod of the cylinder is fixedly connected to the movable block; the ball bearing contacts with the surfaces of the movable block with different height differences to make the lamp board turn and flow into the steering channel.

DETAILED DESCRIPTION

[0031] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0032] Please refer to Figure 1 , is a schematic diagram of the structure of a light board transmission device 100 provided by an embodiment of the utility model, and is synchronously referred to Figure 2 , is an exploded structural diagram of a light board transmission device 100 provided by the utility model. The light board transmission device 100 includes a main channel 110, a turning channel 120, a turning structure 130 and a controller (not shown in the figure), and the controller is used to control the operation of the main channel 110, the turning channel 120 and the turning structure 130.

[0033] The light panel transmission device 100 further includes a support platform 140 , and the main flow channel 110 and the turning flow channel 120 are both disposed on the support platform 140 .

[0034] The main channel 110 is used to transmit the light board 111, which is equivalent to a transmission belt provided on the main channel 110. The light board 111 can be placed on the main channel 110 and move in a predetermined direction after being transmitted by the belt. The main channel 110 is fixed on the support platform 140 through the first support frame 112.

[0035] The diverting channel 120 is disposed at the end of the main channel 110, and the diverting structure 130 is disposed in the diverting channel 120. The diverting structure 130 is used to receive the lamp board 111 transmitted from the main channel 110 and transfer the lamp board 111 to the diverting channel 120, so that the lamp board 111 changes the transmission direction and continues to be transmitted along the diverting channel 120. The diverting channel 120 is fixed on the supporting platform 140 through the second supporting frame 121.

[0036] It is easy to understand that the main channel 110 and the turning channel 120 transport the same batch of light boards 111, so the width of the main channel 110 is the same as the width of the turning channel 120, and both are slightly smaller than the width of the light board 111, so as to facilitate the support of the light board 111 and facilitate stable transmission of the light board 111.

[0037] For further information, please refer to Figure 3 , is a structural schematic diagram of a steering structure 130 provided in an embodiment of the utility model. The steering structure 130 includes a lifting mechanism 131 and an adjusting mechanism 132 . The steering structure 130 is also disposed on a supporting platform 140 .

[0038] The lifting mechanism 131 includes a lifting channel 1311 and a lifting platform 1312. The lifting channel 1311 is fixed to one side of the lifting platform 1312 and is used to communicate with the main channel 110, so as to receive the lamp board 111 transmitted from the main channel 110. A ball bearing 1313 is also provided on the side of the lifting platform 1312 away from the lifting channel 1311. The ball bearing 1313 is used to contact the adjustment mechanism 132. A plurality of guide shafts 1314 are also provided around the ball bearing 1313 on the side of the lifting platform 1312 away from the lifting channel 1311. Each guide shaft 1314 is movably connected to a linear bearing 141 on the support platform 140.

[0039] The adjustment mechanism 132 includes a cylinder 1321 and a movable block 1322 with a height difference on the surface. The top rod of the cylinder 1321 is fixedly connected to the movable block 1322. The movable block 1322 is pulled to move by the extension and contraction control of the top rod of the cylinder 1321, so that the ball bearing 1313 can be in contact with the surfaces of the movable block 1322 with different height differences, so as to achieve the height change control of the lifting platform 1312, and then achieve the direction change of the lamp board 111 into the steering channel 120. Furthermore, in order to facilitate the cylinder 1321 to better pull the movable block 1322 with less resistance, the adjustment mechanism 132 also includes a linear guide rail 1323 and a slider 1324. The slider 1324 is slidably disposed on the linear guide rail 1323, the movable block 1322 is disposed on the slider 1324, and the cylinder 1321 is disposed adjacent to the linear guide rail 1323. Since the movable block 1322 is disposed on the slider 1324, the cylinder 1321 can better pull the movable block 1322 to move. It is easy to understand that the movable block 1322 and the slider 1324 can be disposed integrally or separately.

[0040] Further, see Figure 4 , is a schematic diagram of the working state of a light board transmission device 100 provided by an embodiment of the utility model. As can be seen from the figure, the movable block 1322 includes a first surface and a second surface whose height is lower than the first surface, and the first surface and the second surface are connected by an inclined surface, and in order to facilitate dragging the movable block 1322 with less resistance, the inclined angle θ of the inclined surface compared to the horizontal plane is preferably 15°-25°.

[0041] When the lamp board 111 is transmitted from the main channel 110 to the lifting channel 1311, the height of the lifting channel 1311 is higher than the height of the turning channel 120. At the same time, the ball bearing 1313 contacts the first surface of the movable block 1322. At this time, the ball bearing 1313 will only apply a downward pressure F to the movable block 1322. Therefore, no matter how heavy the mechanical components on the lifting platform 1312 are, or the air pressure fluctuations in the cylinder 1321, it will not cause the movable block 1322 to move. Therefore, when the power of the cylinder 1321 does not change, it can ensure that the lifting platform 1312 is maintained at a constant height.

[0042] Further, see Figure 5, is another working state schematic diagram of a light board transmission device 100 provided by an embodiment of the utility model. When the light board 111 completely enters the lifting channel 1311, the top rod of the cylinder 1321 begins to retract, and the ball bearing 1313 moves until it contacts the second surface of the movable block 1322. At this time, the movement of the ball bearing 1313 drives the lifting platform 1312, the lifting channel 1311 and the light board 111 to move downward together. When the height of the lifting channel 1311 is lower than the height of the turning channel 120, the light board 111 enters the turning channel 120, thereby realizing fast and stable turning of the light board 111.

[0043] Please refer to it synchronously Figure 6-Figure 8 , to schematically introduce the overall working process of the light board transmission device 100:

[0044] Figure 6 A schematic diagram of a lamp board 111 provided by an embodiment of the utility model being transmitted on a main channel 110 is shown. The lamp board 111 is driven by power to be transmitted on the main channel 110 .

[0045] Figure 7 A schematic diagram of the operation of a lamp board 111 on a lifting channel 1311 provided by an embodiment of the utility model is shown. A stop block 1315 and a laser sensor 1316 are also provided on one side of the lifting channel 1311. The stop block 1315 and the laser sensor 1316 are both provided at the edge of the lifting channel 1311. When the lamp board 111 enters the lifting channel 1311 and contacts the stop block 1315, the laser sensor 1316 senses the lamp board 111 and transmits a signal to the controller, and then the controller controls the belt of the lifting channel 1311 to stop rotating, that is, to stop further transmission, and at the same time controls the top rod of the cylinder 1321 to retract so that the ball bearing 1313 moves until it contacts the second surface of the movable block 1322, thereby driving the lifting platform 1312, the lifting channel 1311 and the lamp board 111 to move downward together. Then, as Figure 8 As shown, it is a schematic diagram of the lamp board 111 provided by an embodiment of the utility model on the turning channel 120. When the lifting platform 1312, the lifting channel 1311 and the lamp board 111 move downward together, since the width of the lifting platform 1312 is smaller than the width of the turning channel 120, when the lifting channel 1311 is lower than the turning channel 120, the bottom surface of the lamp board 111 contacts the turning channel 120, and the lamp board 111 smoothly enters the turning channel 120, realizing the change of transmission direction.

[0046] In summary, the utility model provides a steering structure and a light board transmission device, which includes a main channel, a steering channel, a steering structure and a controller. The controller is used to control the transmission of the light board in the main channel and the steering channel, and synchronously controls the movement of the steering structure to realize the transmission and steering of the light board; the steering structure includes a lifting mechanism and an adjusting mechanism. The lifting mechanism includes a lifting channel and a lifting platform. The lifting channel is used to communicate with the main channel to receive the light board, and a ball bearing is provided on the side of the lifting platform away from the lifting channel; the adjusting mechanism includes a cylinder and a movable block with a height difference on the surface. The top rod of the cylinder is fixedly connected to the movable block, and the ball bearing contacts with the surfaces of the movable block with different height differences, so that the light board can flow from the lifting channel into the steering channel to realize the change of transmission direction.
