Description

Technical Field

[0001] The utility model belongs to the technical field of backplane processing, and particularly relates to a metal fixing plate for fixing a display backplane. Background Art

[0002] The backplane is one of the important parts that make up the main body of a display. It is a metal plate that is responsible for firmly fixing various components in the display. The backplane is the thickest part of the display and can provide strong support. Usually, a thin iron sheet is used. However, due to its thin thickness and the fact that the workpiece is usually fixed by pushing and pulling on both sides, the workpiece is prone to deformation during fixation. Now, a device that can effectively prevent deformation of iron workpieces during fixation is proposed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a metal fixing plate for fixing a display backplane, which solves the above problems.

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: A metal fixing plate for fixing a display backplane includes a frame, and also includes: a positioning component for fixing the backplane; the positioning component includes a clamping cylinder A, a frame, and a clamping cylinder. The two clamping cylinders are symmetrically and rotatably connected to both sides of the frame. The two clamping cylinders A are respectively rotatably connected to the frame. A pressing rod A is fixedly connected to the frame, and the other end of the pressing rod A is hinged to the frame.

[0005] Advantageous Effects

[0006] The utility model provides a metal fixing plate for fixing a display backplane, which has the following advantageous effects compared with the prior art:

[0007] Related technicians place the backplane to be processed on the clamping cylinder and start the motor, so that the motor drives the screw rod fixedly connected to its output shaft to rotate synchronously, so that the sliding cylinder threadedly connected to the screw rod starts to perform a linear reciprocating motion along its connection with the frame, so that the pull rod hinged on the sliding cylinder starts to move synchronously, so that the pull rod pulls the pressure rod A hinged to it, causing the pressure rod A to perform a circular motion with its hinge point with the frame as the fulcrum, so that the pressure rod A drives the frame fixedly connected to it to start moving synchronously, so that the clamping cylinder A rotatably connected to it starts to contact the backplane, and the backplane is clamped and fixed under the mutual cooperation of the clamping cylinder and the clamping cylinder A. At the same time, when die pressing is performed, the backplane deforms, causing its two ends to move towards each other, so that the backplane can pull the clamping cylinder and the clamping cylinder A to rotate to adjust its clamping position, so as to prevent the template from being damaged due to the inability to adjust the fixed point when the backplane is fixed for die pressing; at the same time, when the screw rod rotates, the sprocket fixedly connected to it starts to rotate, causing the two sprocket As to start rotating synchronously under the cooperation of the chain meshed with them, so that the shaft fixedly connected to the axis of the sprocket A starts to rotate, causing the shaft to drive the bevel gear A fixedly connected to it to rotate synchronously, so that the bevel gear A drives the bevel gear B meshed with it to start rotating, so that the axle fixedly connected to the axis of the bevel gear B rotates synchronously, so that the push rod rotatably connected to the eccentric part of the eccentric wheel starts to perform a circular motion, so that the two push plates start to perform a linear motion towards each other, and the two push plates cooperate with each other to center the backplane.

[0017] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific clamping cylinder 203 and clamping cylinder A 201 recorded in the above embodiment. For example, damping rubber rings are provided on the clamping cylinder 203 and clamping cylinder A 201. The purpose of this setting is to facilitate increasing the friction generated when the backplane contacts the clamping cylinder 203 and clamping cylinder A 201 in this way.

[0019] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific pressing rod A 204 and pull rod 205 recorded in the above embodiment. For example, the pressing rod A 204 and pull rod 205 should be made of materials processed integrally, and further hardening and clamping treatment should be performed at both ends. The purpose of this setting is to facilitate preventing them from breaking under force in this way.

[0020] Specifically, the sliding cylinder 206 is threadedly connected to a lead screw 207. One end of the lead screw 207 is rotatably connected to the frame 101, the other end of the lead screw 207 is fixedly connected to the output shaft of a motor 309, and the motor 309 is fixedly connected to the frame 101.

[0021] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific lead screw 207 recorded in the above embodiment. For example, the lead screw 207 should be a reciprocating lead screw. The purpose of this setting is that when the slider threadedly connected to it moves to one end, its same-direction rotation can be mechanically controlled, so as to quickly change the movement direction of the slider.

[0022] Specifically, a sprocket 208 is fixedly connected to any one of the lead screws 207. A chain 209 is meshed with the sprocket 208, and two sides of the chain 209 are respectively meshed with sprockets A 301.

[0023] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific sprocket 208 described in the above embodiment. For example, the diameter of the sprocket 208 should be larger than the diameter of the sprocket A 301. The purpose of this setting is to facilitate adjusting the transmission ratio in this way.

[0024] Specifically, shafts 302 are respectively fixedly connected to the centers of the two sprockets A 301, and the shafts 302 are rotatably connected to the frame 101.

[0025] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific shaft 302 described in the above embodiment. For example, a bearing ring is provided at the connection between the shaft 302 and the frame 101. The purpose of this setting is to facilitate reducing the friction at the connection in this way.

[0026] Specifically, bevel gears A 303 are fixedly connected to the two shafts 302. The bevel gears A 303 are meshed with bevel gears B 304. A wheel shaft 305 is fixedly connected to the center of the bevel gear B 304, and the wheel shaft 305 is rotatably connected to the frame 101.

[0027] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific frame 101 described in the above embodiment. For example, universal wheels are provided at the bottom of the frame 101. The purpose of this setting is to facilitate controlling the movement of the device in this way, thereby adjusting its position.

[0028] Specifically, eccentric wheels 306 are respectively fixedly connected to the tops of the two wheel shafts 305. A push rod 307 is rotatably connected to the eccentric part of the eccentric wheel 306. The other end of the push rod 307 is hinged to a push plate 308, and the push plate 308 is slidably connected to the frame 101.

[0029] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific push plate 308 described in the above embodiment. For example, damping rubber strips should be provided at the connection between the push plate 308 and the frame 101. The purpose of this setting is to facilitate increasing the damping at the connection in this way, so as to make it slide smoothly.

[0030] In the embodiment of the present utility model, relevant technicians place the backplane to be processed on the clamping cylinder 203 and start the motor 309, so that the motor 309 drives the lead screw 207 fixedly connected to its output shaft to rotate synchronously, so that the sliding cylinder 206 threadedly connected to the lead screw 207 starts to perform a linear reciprocating motion along its connection with the frame 101, so that the pull rod 205 hinged on the sliding cylinder 206 starts to move synchronously, so that the pull rod 205 pulls the pressure rod A 204 hinged to it, so that the pressure rod A 204 performs a circular motion with its hinge point with the frame 101 as the fulcrum, so that the pressure rod A 204 drives the frame 202 fixedly connected to it to start to move synchronously, so that the clamping cylinder A 201 rotatably connected thereto starts to contact the backplane. Under the mutual cooperation of the clamping cylinder 203 and the clamping cylinder A 201, the backplane is clamped and fixed. At the same time, when die pressing is performed, the backplane deforms, causing its two ends to move towards each other, so that the backplane can pull the clamping cylinder 203 and the clamping cylinder A 201 to rotate to adjust its clamping position, so as to prevent the template from being damaged due to the inability to adjust the fixed point when fixing the backplane for die pressing; at the same time, when the lead screw 207 rotates, the sprocket 208 fixedly connected thereto starts to rotate, so that the two sprockets A 301 start to rotate synchronously under the cooperation of the chain 209 meshed with them, so that the shaft 302 fixedly connected to the axis of the sprocket A 301 starts to rotate, so that the shaft 302 drives the bevel gear A 303 fixedly connected to it to rotate synchronously, so that the bevel gear A 303 drives the bevel gear B 304 meshed with it to start to rotate, so that the axle 305 fixedly connected to the axis of the bevel gear B 304 rotates synchronously, so that the push rod 307 rotatably connected to the eccentric part of the eccentric wheel 306 starts to perform a circular motion, so that the two push plates 308 start to perform a linear motion towards each other, and the two push plates 308 cooperate with each other to center and align the backplane.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0032] The so-called fixed connection in this application means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0033] (1) Detachable connection: Fix components together using screws, splines, wedge pins, etc. This connection method can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, and wedge pins), and they must be tightened appropriately.

[0034] (2) Non-detachable connection: Mainly refers to welding, riveting, and mortise fitting, etc. Since forging, sawing, or oxygen cutting is required to disassemble during maintenance or replacement, the spare parts generally cannot be used a second time. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0035] The sliding connection referred to in this application means that a component can slide along a linear trajectory, and the hinged connection referred to in this application means that a component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and the hinged connection referred to in this application can also be damped, so that the component has the ability to maintain at the desired position.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
