Fig. 1 shows a schematic diagram of a liquid crystal panel tool according to an embodiment of the utility model, and fig. 2 shows a top view of the liquid crystal panel tool. The liquid crystal screen tool generally comprises a bottom plate 1 with a supporting surface 11; a back plate 2 arranged above the supporting surface 11 in a sliding way, and a pushing device 3. Wherein the support surface 11 of the base plate 1 is a substantially horizontally extending plane having an abutment edge 12 extending in a first direction, which abutment edge 12 is arranged to be convex towards a direction perpendicular to the plane of the support surface 11, shown as being convex upwards in fig. 1. The abutment flange 12 may have a variety of forms, including but not limited to: one side edge of the bottom plate 1 is bent upwards to form an abutting edge 12, or a long strip-shaped structure is fixedly arranged on the supporting surface 11 of the bottom plate 1 to be used as the abutting edge 12. The position of the abutment edge 12 is not limited to one side of the base plate 1, and may be located at any position on the support surface 11 of the base plate 1. The back plate 2 is slidably arranged in a second direction with respect to the base plate 1, wherein the second direction intersects the first direction. Preferably, the second direction may be perpendicular to the first direction. The pushing device 3 is connected with the back plate 2 and can push the back plate 2 to move back and forth along the second direction.
In an embodiment of the present invention, the lcd panel assembly may have a plurality of back panels 2 located on the same side of the abutting edge 12, the plurality of back panels 2 being parallel to each other and spaced apart from each other in the first direction, i.e. the plurality of back panels 2 being parallel to each other and spaced apart from each other in the direction extending along the abutting edge 12. Preferably, a plurality of back plates 2 are arranged obliquely to the support surface 11 on the same side of the abutment edge 12. The acute angle formed between the back plate 2 and the support surface 11 may be referred to as a tilt angle. When the tool is used, the liquid crystal screen needs to be placed on the supporting surface 11 between the abutting edge 12 and the back plate 2, so that the bottom edge of the liquid crystal screen contacting the supporting surface 11 or a plurality of points on the bottom edge abut against one side of the abutting edge 12, and meanwhile, one surface of the liquid crystal screen facing the back plate 2 is abutted against the back plates 2. The side of the back plate 2 facing the abutment edge 12 for the liquid crystal screen is referred to as the contact side. Each back plate 2 will correspond to a separate pushing device 3 to independently adjust the distance of the back plate 2 relative to the abutting edge 12, i.e. the distance of the back plate 2 relative to the abutting edge 12 in the extending direction perpendicular to the abutting edge 12, so as to adapt to liquid crystal screens of different specifications.
In the embodiment of the present invention, the number of the rear plates 2 is preferably three to support two side portions and a middle portion of the liquid crystal panel, respectively. The back plate 2 may be arranged in a long strip shape, for example, the contact surface of the strip-shaped back plate 2 facing the abutting edge 12 is arranged to have a width of 10-15mm along the first direction, so as to increase the contact area of the back plate 2 and the liquid crystal screen and reduce the pressure exerted by the liquid crystal screen on the back plate 2. Preferably, the surfaces of the abutment edge 12 and the back plate 2 facing each other may be laid with a flexible structural layer to avoid damage to the liquid crystal panel during placement. As further shown in fig. 2, the contact surfaces of the first back plate 21 and the third back plate 23 on both sides can be respectively configured to have arc surfaces opposite to each other, and the second back plate 22 between the two is configured to be a plane, so that the contact surfaces of the first back plate 21, the second back plate 22 and the third back plate 23 generally define a complete arc surface to conform to the arc surface of the curved screen. Because, the contact surface of first backplate 21, second backplate 22 and third backplate 23 all is provided with flexible structure, and the slight elastic deformation of this flexible structure also can ensure that first backplate 21, second backplate 22 and third backplate 23 can be applicable to the curved surface screen of multiple different models. Alternatively, the operator may set different numbers and different structures of the back plates 2 and the corresponding pushing devices 3 according to the actual working conditions.
In the embodiment shown in fig. 1, the pushing device 3 has the form of a screw pair, comprising a screw 32 and a nut 33 cooperating with each other. Specifically, the screw 32 is provided to extend in the second direction, and is rotatable about the axis of the screw 32 with respect to the base plate 1; the nut 33 is provided to be screwed with the lead screw 32. Therefore, as the screw rod 32 rotates around the shaft, the nut 33 in threaded connection with the screw rod is translated along the axial direction of the screw rod 32, and further the nut 33 drives the back plate 2 to move along the second direction relative to the abutting edge 12 along with the rotation of the screw rod 32 around the shaft. The rotation of the screw 32 may be manually driven by an operator or may be driven by a driving mechanism such as the motor 31. In the case of using the motor 31, the main body of the motor 31 can be fixed to the bottom plate 1, and the output end of the motor 31 can be coaxially and fixedly connected to the screw rod 32, so that when the motor 31 is started, the output end drives the screw rod 32 to coaxially rotate clockwise/counterclockwise, and simultaneously drives the back plate 2 to advance/retreat in the second direction.
Preferably, the pushing device 3 may further include a connecting arm 34 connecting the back plate 2 to the nut 33. In this embodiment, the connecting arm 34 defines a rotation locus of the backboard 2 relative to the connecting point by its arc-shaped structure, and adjusts the inclination angle of the backboard 2 relative to the supporting surface 11 by adjusting its length. Specifically, the connecting arm 34 may include a first arcuate link connected to the nut, a second arcuate link connected to the back plate, and a locking mechanism. The first arc-shaped connecting rod is marked with scales along the arc-shaped edge so as to display the inclination angle of the back plate 2; the second arc-shaped connecting rod is sleeved on the first arc-shaped connecting rod and can slide relative to the first arc-shaped connecting rod; a locking mechanism is provided to releasably lock the position of the second arcuate link relative to the first arcuate link. In an embodiment of the utility model, the locking mechanism may comprise a locking screw extending through one side of the second curved link and abutting against the same side of the first curved link to lock/unlock the relative positions of the first and second curved links by screwing/unscrewing the locking screw. Preferably, the side of the first curved link that contacts the locking screw may have an uneven surface, such as a scalloped protrusion, to increase friction between the side and the locking screw.
Further preferably, the lcd panel tool further comprises a distance sensor 4 and a controller 5 communicatively connected to the distance sensor 4, wherein the distance sensor 4 is disposed on the contact surface of the back plate 2 facing the abutting edge 12 to sense the distance between the contact surface and the lcd panel. In the scenario where the operator manually drives the back plate 2 to move in the second direction, the controller 5 may issue an alarm for the attention of its operator when the measurement result of the distance sensor 4 reaches a predetermined threshold. Fig. 3 shows a block diagram of an automated control principle of the pushing device 3 of the lcd panel tool according to the present invention. In the case where the back panel 2 is driven to move in the second direction by the driving mechanism, the controller 5 may be communicatively connected to the driving mechanism and controls the start and stop of the driving mechanism based on the measurement result from the distance sensor 4 to achieve automatic adjustment of the position of the back panel 2.
In another embodiment of the present invention, the lcd panel assembly further includes a leg 6 for supporting the bottom panel 1. The number of the supporting legs 6 includes but is not limited to 4, and the height of the supporting legs along the direction perpendicular to the supporting surface 11 is adjustable, so that operators with different heights can conveniently use the liquid crystal screen tool.
The liquid crystal screen tool provided by the utility model can follow the following steps in the using process:
in the first step, the controller 5 controls the back plates 2 of the plurality of pushing devices 3 to move to a position far away from the abutting edge 12 along the second direction.
And step two, vertically placing the liquid crystal screen on the supporting surface 11 of the bottom plate 1, and continuously maintaining the liquid crystal screen. The operator can manually carry the liquid crystal panel onto the support surface 11 and hold the liquid crystal panel, for example, in a hand-held manner; or by an automated transfer mechanism, such as a robot, to automatically transfer the liquid crystal panel onto the support surface 11 and hold the liquid crystal panel, for example, in a sandwiched manner. If the liquid crystal screen is a plane liquid crystal screen, one surface of the liquid crystal screen is attached to the inner side surface of the abutting edge 12; if the liquid crystal screen is a curved surface liquid crystal screen, the concave surface of the liquid crystal screen faces the abutting edge 12, and the vertical edges on the two sides of the liquid crystal screen are attached to the inner side surface of the abutting edge 12.
And step three, the controller 5 controls the back plates 2 of the plurality of pushing devices 3 to move along the second direction to gradually approach the liquid crystal display screen, and simultaneously the distance sensors 4 respectively detect the distance between the back plate 2 and the liquid crystal display screen corresponding to the distance sensors and transmit the detection result to the controller 5.
Step four, the controller 5 controls the back plates 2 of the plurality of pushing devices to stop moving in response to the detection result reaching a predetermined threshold.
And fifthly, releasing the liquid crystal screen, and enabling the contact surfaces of the back plates 2 to be attached to the other surface of the liquid crystal screen to form effective support.
Through the steps, the placement stability of the liquid crystal screen can be ensured. In the embodiment of the present invention, the predetermined threshold value may be set to 0-20mm, and the inclination angle of each backboard 2 with respect to the supporting surface 11 may be adjusted depending on the height at which the distance sensor 4 is set and the magnitude of the predetermined threshold value. It will be appreciated that although the plurality of backplates 2 are each controlled in displacement by a respective controller 5 and pusher 3, each has an equal predetermined threshold to ensure that each backplate 2 is able to effectively support the liquid crystal panel. When the liquid crystal screen tool is used for supporting a planar liquid crystal screen, one surface (when the preset threshold value is 0) of the liquid crystal screen or the bottom edge (when the preset threshold value is not 0) of the contact supporting surface 11 abuts against the inner side surface of the abutting edge 12, and the opposite other surface is attached to the contact surfaces of the back plates 2; when the liquid crystal screen tool is used for supporting a curved liquid crystal screen, vertical edges on two sides of a concave surface of the liquid crystal screen (when the preset threshold value is 0) or two points (when the preset threshold value is not 0) on the bottom edge of the contact supporting surface 11, which are positioned on the edges on two sides of the liquid crystal screen, are abutted to the inner side surface of the abutting edge 12, and the opposite other surface is attached to the contact surfaces of the plurality of back plates 2.
In summary, the lcd panel fixture according to the present invention can adjust the positions and the tilt angles of the plurality of back panels 2 according to the shape and the specification of the lcd panel, so that the lcd panel fixture can stably support lcd panels with different shapes, sizes and specifications in a fitting manner. In addition, the arrangement of the distance sensor 4 and the controller 5 enables the supporting process of the liquid crystal screen tool to be automatically controlled, and more stable and accurate supporting is achieved.
