This manual flipping method often requires four operators to work at the same time, and the flipping rate will be seriously affected by the size of the product. In addition, manual flipping by personnel is prone to safety accidents caused by factors such as physical exhaustion. Utility Model Content

[0006] Furthermore, the flip mechanism further comprises an abutment component, which is mounted on the flip frame and can be extended relative to the display screen and then abut the display screen. The abutment component abuts the display screen to prevent the display screen from shifting during the flipping process.

[0007] Furthermore, two of the clamping components and the abutting components are provided, and the two abutting components cooperate with the two clamping components to fix the display screen from four sides of the display screen. The two abutting components and the two clamping components cooperate to fix the display screen from four directions, ensuring the stability of the display screen during clamping and flipping.

[0008] Furthermore, the flip mechanism further comprises a first lifting assembly and a lifting frame, wherein the first lifting assembly is mounted on the main frame, and a power end is connected to the lifting frame, and the flip power assembly is mounted on the lifting frame. The lifting frame is driven up and down by the first lifting assembly, and the flip power assembly connects the lifting frame and the flip frame, thereby realizing the lifting and flipping of the flip frame.

[0009] Furthermore, the flip frame and the lifting frame are arranged at intervals in the vertical direction, and the length of the lifting frame is greater than the length of the flip frame, and the width of the lifting frame is greater than the width of the flip frame.

After the clamping assembly clamps the display screen in place, the flipping mechanism rises to a flippable position, and the flipping power assembly drives the flipping frame to flip 180° relative to the main frame.

DETAILED DESCRIPTION

[0024] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0025] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0027] In the field of display production technology, it is often necessary to flip the display screen 180° for operation, mainly based on the needs of production process and quality control. For example, flipping the display screen 180° can better check the quality of the screen, such as whether there are problems such as color difference, bad pixels, bright lines, etc.; these problems may be ignored in normal state, but are more easily discovered in the flipped state; or flipping the display screen can test the performance of the screen in extreme conditions, such as whether there will be problems such as reduced brightness and color distortion in the inverted state, which is necessary to ensure that the screen can work normally under different conditions of use; and flipping the display screen can better check the assembly effect of the screen, such as whether there are problems such as missing installation and wrong installation. At the same time, flipping the screen can also check the fit between the screen and the bracket to ensure that the screen is firmly fixed. However, in the current display screen flipping process, full manual flipping or semi-automatic flipping is generally adopted. Full manual flipping is to arrange four operators under the four corners of the display screen, and the four operators manually lift the display screen and flip it 180°; semi-automatic flipping is that four operators lift the display screen to the semi-automatic flipping machine for adsorption, and then use the semi-automatic flipping machine to flip the display screen. These two methods undoubtedly have manual operation links, which makes it very difficult to flip large-size display screens of 70 inches and above, which not only affects the overall work efficiency, but also easily causes safety accidents.

[0028] Therefore, this embodiment provides a device capable of realizing full-automatic flipping of a display screen, such as Figure 1-Figure 5 As shown, it includes: a main frame 1, a flipping mechanism 2 and a conveying mechanism 3; the flipping mechanism 2 is slidably installed on the main frame 1 and can be lifted and lowered relative to the main frame 1, the flipping mechanism 2 includes a flipping power component 201, a flip frame 202 and a clamping component 203, the clamping component 203 is slidably installed on the flip frame 202, the clamping component 203 is used to clamp the display screen, the power output end of the flipping power component 201 is connected to the flip frame 202, and is used to drive the flip frame 202 and the display screen to flip 180°; the conveying mechanism 3 is arranged on the main frame 1, the conveying mechanism 3 includes a conveyor belt 301, a first positioning plate 302 and a second positioning plate, the first positioning plate 302 and the second positioning plate are both arranged on the conveyor belt 301, the first positioning plate 302 is used to cooperate with the display screen before flipping for positioning and fixing, and the second positioning plate is used to cooperate with the display screen after flipping for positioning and fixing.

[0029] Based on the above scheme, at least two positioning plates are provided, namely, a first positioning plate 302 and a second positioning plate. This is because the display screen has a relative front and back, and the front and back structures are different, and corresponding positioning plates are required for lossless assembly, that is, the first positioning plate 302 is assembled with the front of the display screen, and the second positioning plate is assembled with the back of the display screen. The front and back of the display screen described here are relative. In simple terms, two different positioning plates are required to adapt to the assembly of the two surfaces of the display screen. In the specific workflow, the display screen is assembled onto the first positioning plate 302 and transported to the bottom of the flip mechanism 2 along with the conveyor belt 301. The display screen needs to be within the range of the flip frame 202. The flip mechanism 2 is lowered as a whole to a position where the clamping assembly 203 can clamp the display screen. The clamping assembly 203 moves relative to the direction of the display screen and completes the clamping action of the display screen. The flip mechanism 2 rises to a position where it can flip. The flip position described here means that the flip frame 202 will not touch the conveying mechanism 3 when flipping. The flip power assembly 201 drives the flip frame 202 to flip around the axis. After flipping 180°, the flip frame 20 2 and the display screen are flipped horizontally, and the side of the display screen that was originally facing downward becomes facing upward. After the display screen is flipped, the second positioning plate moves to the bottom of the display screen along with the conveyor belt 301, and the flipping mechanism 2 descends to the position where the display screen and the second positioning plate are assembled. The clamping assembly 203 releases the display screen and resets it. The display screen is accurately assembled on the second positioning plate and is transported to the next operation process along the conveyor belt 301, realizing the fully automatic flipping of the display screen. No manual operation is required throughout the process. In addition, the first positioning plate 302 and the second positioning plate are used to assemble the display screen in different states respectively, which can be seamlessly connected to the production line to improve production efficiency.

[0030] In addition, both the first positioning plate 302 and the second positioning plate can be transferred to the conveyor belt 301 or removed from the conveyor belt 301. The specific actions are as follows: when the display screen is detached from the first positioning plate 302, the conveyor belt 301 is reversed, and the first positioning plate 302 is conveyed to the module section. At the same time, the module section conveys the second positioning plate to the conveyor belt 301 and moves it to the bottom of the flipped display screen. The module section mentioned here refers to the previous operation process of the display screen before performing the flipping action.

[0031] As an optional specific implementation scheme, the first positioning plate 302 and the second positioning plate can be alternately arranged on the conveyor belt 301. After the display screen is detached from the first positioning plate 302, the rear second positioning plate replaces the position of the first positioning plate 302 to complete the operation of assembling the flipped display screen.

[0032] It is worth mentioning that a first photoelectric sensor is provided on the conveyor belt 301, and a second photoelectric sensor is provided on the clamping assembly 203. After the first photoelectric sensor on the conveyor belt 301 detects that the first positioning plate 302 or the second positioning plate is in place, the flipping mechanism 2 descends to clamp the display screen or place the display screen. When the second photoelectric sensor on the clamping assembly 203 detects that the clamping assembly 203 moves to a position where it can clamp the display screen, the clamping assembly 203 clamps the display screen.

[0033] Furthermore, the flip mechanism 2 also includes a contact component 204, which is installed on the flip frame 202 and can be extended relative to the direction of the display screen and then contact the display screen. After the clamping component 203 stably clamps the display screen, the contact component 204 can be extended in the direction of the display screen, and then the contact component 204 can contact the display screen. The clamping component 203 and the contact component 204 can cooperate to prevent the display screen from shifting during the flipping process. In addition, in this solution, the structure of the contact component 204 and the display screen is made of elastic material to avoid damage to the display screen due to contact.

[0034] Furthermore, two clamping components 203 and two abutting components 204 are provided, and the two abutting components 204 cooperate with the two clamping components 203 to fix the display screen from four sides of the display screen. The two clamping components 203 are respectively located on the left and right sides of the display screen to clamp the display screen, and the two abutting components 204 are located on the front and back sides of the display screen to abut the sides of the display screen. The two abutting components 204 and the two clamping components 203 cooperate to fix the display screen from four directions, ensuring the stability of the display screen during clamping and flipping.

[0035] Optionally, the flip mechanism 2 further includes a first lifting assembly 205 and a lifting frame 206, wherein the first lifting assembly 205 is mounted on the main frame 1, and the power end is connected to the lifting frame 206, and the flip power assembly 201 is mounted on the lifting frame 206. In this solution, the first lifting assembly 205 is fixed on the main frame 1, and the lifting frame 206 is connected to the flip frame 202 through the flip power assembly 201. The first lifting assembly 205 drives the lifting frame 206 to move up and down, and utilizes the connection relationship between the flip power assembly 201 and the flip frame 202 to drive the flip frame 202 to move up and down. In addition, since the flip power assembly 201 is fixed on the lifting frame 206, the flip frame 202 can also be flipped by the flip power assembly 201 on the basis of the lifting of the flip frame 202, thereby realizing the horizontal flipping of the display screen.

[0036] It should be noted that the flip frame 202 and the lifting frame 206 are arranged at intervals in the vertical direction, and the length of the lifting frame 206 is greater than the length of the flip frame 202, and the width of the lifting frame 206 is greater than the width of the flip frame 202. In simple terms, the area surrounded by the lifting frame 206 is larger than the area of ​​the flip frame 202, that is, the flip frame 202 is within the vertical projection area of ​​the lifting frame 206. The purpose of this design is to provide a flipping space for the flip frame 202, so that the flip frame 202 will not touch the lifting frame 206 when flipping, and the lifting frame 206 can also drive the flip frame 202 to rise and fall.

[0037] Preferably, the flipping power assembly 201 includes a flipping motor 2011 and a transmission fitting 2012, the flipping motor 2011 is installed on the lifting frame 206, and the power end is connected to the flipping frame 202, the transmission fitting 2012 connects the flipping frame 202 and the lifting frame 206, and is arranged on two opposite sides of the flipping frame 202 with the flipping motor 2011, and the flipping motor 2011 can drive the flipping frame 202 to flip relative to the lifting frame 206 with the cooperation of the transmission fitting 2012. The flip motor 2011 is arranged on the left side of the flip frame 202, and the transmission matching piece 2012 is relatively arranged on the right side of the flip frame 202. Here, relatively means that the flip motor 2011 and the transmission matching piece 2012 are arranged along the same straight line, and the straight line is parallel to the side surface of the flip frame 202 in the length direction. The reason for setting the transmission matching piece 2012 is that the flipping power of the flip frame 202 is provided by the flip motor 2011, which belongs to unilateral power output. In this way, the flip frame 202 is prone to instability during the flipping process. Therefore, the transmission matching piece 2012 is arranged on the other side of the flip frame 202. 012, the transmission fitting 2012 is equivalent to the transmission structure between the flip frame 202 and the lifting frame 206. When the flip motor 2011 drives the flip frame 202 to flip, the flip frame 202 and the lifting frame 206 are connected and rotated through the transmission fitting 2012, so that the flip frame 202 can be smoothly flipped around the axis between the flip motor 2011 and the transmission fitting 2012, and the flip motor 2011 and the transmission fitting 2012 are arranged on the opposite sides of the flip frame 202, so that the flip frame 202 will be subjected to more balanced force when flipping, reducing the probability of position deviation.

[0038] At the same time, a conductive slip ring 207 for wires to pass through is provided on one side of the flip frame 202. The entire flip mechanism 2 needs to be connected by wires including the clamping motor 2031, the flip motor 2011, the second photoelectric sensor, etc. If these wires are arranged randomly, the wires will inevitably be entangled with each other when the flip frame 202 is flipped. Therefore, a conductive slip ring 207 is specially provided to solve the wire entanglement problem that occurs during the flipping process of the flip frame 202. The specific working principle is that the conductive slip ring 207 adopts a precise rotating shaft design to ensure that the conductive slip ring 207 remains stable during the rotation process, thereby reducing the entanglement of the wires caused by the unstable rotating shaft. In addition, flat or spring-type wires are preferably used, which can automatically unfold with the rotation of the conductive slip ring 207 to avoid entanglement.

[0039] In some embodiments, the first lifting assembly 205 includes a lifting motor 2051, a transmission shaft 2052 and two screw rods 2053, the two screw rods 2053 are respectively connected to the two sides of the lifting frame 206, the power end of the lifting motor 2051 is connected to the transmission shaft 2052, and the transmission shaft 2052 is respectively engaged with the two screw rods 2053 for transmission. In this scheme, the lifting motor 2051 is arranged on one side of the main frame 1, and the transmission shaft 2052 is arranged along the length direction of the main frame 1 and connected to the two screw rods 2053, the two screw rods 2053 are respectively located on both sides of the main frame 1, one of which is on the same side as the lifting motor 2051. When in action, the lifting motor 2051 starts to drive the transmission shaft 2052 to rotate, and the transmission shaft 2052 drives the two screw rods 2053 to rotate synchronously, and the lifting frame 206 is lifted and lowered under the rotation of the two screw rods 2053.

[0040] In addition, the clamping assembly 203 includes a clamping motor 2031, a movable plate 2032, a cylinder 2033 and a clamping plate 2034. The clamping motor 2031 is installed on the flip frame 202, the movable plate 2032 is slidably installed on the flip frame 202 and is connected to the power end of the clamping motor 2031, the cylinder 2033 is installed on the movable plate 2032, the clamping plate 2034 is connected to the cylinder 2033, the movable plate 2032 can move relative to the flip frame 202 under the drive of the clamping motor 2031, and the clamping plate 2034 can clamp toward each other or release away from each other under the drive of the cylinder 2033. The specific operation process of the clamping assembly 203 is as follows: the clamping motor 2031 drives the moving plate 2032 to move toward the display screen. After the plate 2032 moves into position, the cylinder 2033 on the moving plate 2032 controls the clamping plate 2034 to move relative to the display screen, thereby causing the clamping plate 2034 to clamp the display screen from the upper and lower sides to complete the clamping of the display screen. Here, two clamping plates 2034 are provided, which are relatively arranged on the upper and lower sides of the display screen. It should be noted that the material of the side of the clamping plate 2034 in contact with the display screen is an elastic material to avoid damage to the display screen during the clamping process.

[0041] Optionally, the conveying mechanism 3 further includes a second lifting component 303 and a conveying frame, the conveyor belt 301 is arranged on the conveying frame, the second lifting component 303 is installed at the bottom of the main frame 1, and the power end is connected to the conveying frame, and the conveying frame is slidably connected to the main frame 1. The second lifting component 303 is used to drive the conveying frame to move up and down, so that the conveyor belt 301 located on the conveying frame can move up and down. The reason why the conveyor belt 301 is set to move up and down here is to improve the flipping efficiency. While the flipping mechanism 2 clamps the display screen to move upward, the conveyor frame and the conveyor belt 301 can be controlled to move downward through the second lifting component 303, so that the distance between the flip frame 202 and the conveyor belt 301 is maximized in the shortest time. The maximization here only refers to the distance that the flip frame 202 can flip, thereby improving the flipping efficiency.

[0042] In addition, since the movement of the conveying frame is achieved through the unilateral lifting power provided by the second lifting component 303, in order to ensure that the lifting level of the conveying frame remains consistent, fixed pulleys are installed at the four end corners of the main frame 1, and the unilateral power of the second lifting component 303 is transmitted to the surroundings through a chain connection to ensure that the conveying frame and the conveyor belt 301 can be lifted and lowered smoothly.

[0043] In summary, the device can adapt to the fixation of display screens of different sizes by moving the clamping component 203 and extending the abutment component 204, and is compatible with display screen products ranging from 65 inches to 86 inches, and can achieve fully automatic flipping of the display screen; and the clamping action and flipping action corresponding to different models of display screens can be set in the controller of the device, so that the display screen model that needs to be flipped can be directly selected without setting the operating parameters separately, which is fast and simple; in addition, the device can adjust the flipping rhythm according to specific production needs to improve the flipping efficiency, thereby improving the overall work efficiency.
