In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] See also Figure 1 , the positioning mechanism 10 provided in the embodiment of the present application is now described. The positioning mechanism 10 provided in the embodiment of the present application includes a carrier 101, a first reference member 102, a first push member 103, a second reference member 104 and a second push member 105, and defines a first direction and a second direction, the first direction is recorded as X, and the second direction is recorded as Y, the first direction and the second direction are parallel to the table surface of the carrier 101, and have an angle; the first reference member 102 is arranged on the carrier 101, specifically taking one end of the first reference member 102 close to the carrier 101 in the first direction as an example; the first push member 103 is arranged on the carrier 101, specifically taking the other end of the first push member 103 close to the carrier 101 in the first direction as an example, the first push member 103 is opposite to the first reference member 102 along the first direction, and can be moved along the first direction to push the workpiece carried by the carrier 101, so that the workpiece is pressed against the carrier 101 along the first direction. The second reference member 104 is arranged on the platform 101, and specifically, one end of the second reference member 104 in the second direction close to the platform 101 is arranged as an example; the second pushing member 105 is arranged on the platform 101, and specifically, the other end of the second pushing member 105 in the second direction close to the platform 101 is arranged as an example, the second pushing member 105 is opposite to the second reference member 104 along the second direction, and can be moved along the second direction to push the workpiece carried by the platform 101, so that the workpiece is pressed against the second reference member 104 along the second direction; the first reference member 102 and the first pushing member 103 are respectively provided with a rotatable first guide wheel 106, and the first reference member 102 and the first pushing member 103 respectively press the workpiece with the corresponding first guide wheel 106, and the first guide wheel 106 can roll along the corresponding edge of the workpiece that is pressed.

[0037] The positioning mechanism 10 provided in the embodiment of the present application is used to position the display screen as an example. Of course, the positioning mechanism 10 in the embodiment of the present application can also be used to position other products without limitation. The carrier 101 is used to carry the display screen. The embodiment of the present application takes the first direction and the second direction as perpendicular, and the table surface of the carrier 101 as an example of a horizontal plane. The length and width of the display screen are placed on the table surface of the carrier 101 roughly along the first direction and the second direction, that is, the length and width of the display screen can have a certain angle relative to the first direction and the second direction, respectively, to allow a certain tolerance for the placement direction of the display screen, thereby helping to save related precision control costs and time.

[0038] The first pushing member 103 is controlled to move along the first direction and contact one end of the display screen close to the first pushing member 103 along the first direction, and then the display screen is pushed to move along the first direction on the table surface of the carrier 101 until one end of the display screen away from the first pushing member 103 along the first direction hits the first reference member 102, and the first pushing member 103 is stopped. Under the clamping effect of the first pushing member 103 and the first reference member 102 in cooperation with each other along the first direction, the display screen can also be straightened along the first direction and the second direction to correct the deflection angle when placed.

[0039] Similarly, the second pushing member 105 is controlled to move in the second direction and contact the end of the display screen that is close to the second pushing member 105 in the second direction, and then the display screen is pushed to move in the second direction on the table surface of the carrier 101 until the end of the display screen that is away from the second pushing member 105 in the second direction hits the second reference member 104, and the second pushing member 105 is stopped. Under the clamping effect of the second pushing member 105 and the second reference member 104 in the second direction, the display screen can also be adjusted in the first direction and the second direction to correct the deflection during placement, wherein the first pushing member 103 and the second pushing member 105 can operate successively or simultaneously.

[0040] Among them, the first guide wheel 106 respectively arranged on the first reference member 102 and the first pushing member 103 can help reduce the resistance during the alignment of the display screen. It can be understood that during the alignment of the display screen, the first guide wheel 106 can roll along the edge of the display screen that is supported. Compared with the relative sliding friction generated by the extrusion effect, the first guide wheel 106 can effectively protect the edge of the display screen from wear and tear, and the alignment resistance is smaller. At the same time, when the aligned display screen is pushed by the second pushing member 105 along the second direction, the first guide wheel 106 rolls along the second direction with the edges on both sides of the display screen in the first direction, has a guiding effect, and helps the second pushing member 105 to push the positioning.

[0041] Furthermore, the first reference member 102 and the second reference member 104 are respectively used as positioning references and are set according to actual positioning. When the long and wide ends of the display screen are respectively abutted against the first reference member 102 and the second reference member 104, the target position can be determined. The first pushing member 103 arranged relative to the first reference member 102 along the first direction and the second pushing member 105 arranged relative to the second reference member 104 along the second direction are used to push the display screen and make the long and wide ends of the display screen abut against the first reference member 102 and the second reference member 104 respectively. At the same time, the problem of low correction and positioning accuracy of the display screen is solved. In addition, the positioning mechanism 10 of the embodiment of the present application has a simple and efficient structure and operation, which also helps to save costs.

[0042] Among them, the first reference member 102, the first pushing member 103, the second reference member 104 and the second pushing member 105 can be connected to the carrier 101, or can be separately arranged, depending on the actual implementation scenario. During the positioning process, the first reference member 102 and the second reference member 104 are fixed relative to the carrier 101 to be used as a positioning reference, and the first pushing member 103 and the second pushing member 105 move relative to the carrier 101 to provide a driving force for the display screen.

[0043] It should be noted that the structure of the first reference member 102 is set along the second direction as an example, while the structure of the second reference member 104 is set along the first direction as an example, that is, when the display screen is against the first reference member 102, the corresponding end of the display screen is fitted with the first reference member 102 along the second direction. Similarly, when the display screen is against the second reference member 104, the corresponding end of the display screen is fitted with the second reference member 104 along the first direction, thereby achieving the effect of straightening the display screen.

[0044] See also Figure 2 and Figure 3 When the first reference member 102 and the first pushing member 103 cooperate to position the two ends of the display screen in the first direction, the two ends of the display screen in the first direction respectively abut against the rims of the first guide wheel 106 provided on the first reference member 102 and the first pushing member 103. It can be understood that the rotation axis direction of the first guide wheel 106 is perpendicular to the table surface of the carrier 101. Of course, it can also have a certain angle so that the first guide wheel 106 can meet the above functions.

[0045] Of course, the number of first guide wheels 106 set on the first reference member 102 and the first pushing member 103 can be determined according to needs. In the embodiment of the present application, it is taken as an example that multiple first guide wheels 106 are respectively set on the first reference member 102 and the first pushing member 103, and the guide wheels on the first reference member 102 and the first pushing member 103 are respectively spaced along the second direction to help the display screen to be aligned after positioning.

[0046] Among them, the first guide wheel 106 of the embodiment of the present application takes a wheel-shaped structure as an example, of course, it can also be other structures that can be used for rolling conduction, such as balls, or it can be a combination of multiple guide wheels and transmission belts to achieve the setting of guiding the display screen along the second direction, etc. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the scope of protection of this application.

[0047] See also Figure 2 and Figure 4Similarly, the second reference member 104 and the second push member 105 are respectively provided with a rotatable second guide wheel 107, and the second reference member 104 and the second push member 105 respectively use the corresponding second guide wheels 107 to push against the workpiece, and the second guide wheel 107 can roll along the corresponding edge of the workpiece that is pushed against.

[0048] The second guide wheel 107 is configured and works in the same manner as the first guide wheel 106, and will not be described in detail herein. The first guide wheel 106 and the second guide wheel 107 may be configured at the same time, or only one of them may be configured. In the embodiment of the present application, the first reference member 102 and the first push member 103 are respectively configured with the first guide wheel 106, and the second reference member 104 and the second push member 105 are respectively configured with the second guide wheel 107 as an example.

[0049] See also Figure 2 and Figure 3 Furthermore, the first push piece 103 in the above embodiment may also be provided with a pressure sensor 108. The first guide wheel 106 arranged on the first push piece 103 can be elastically extended and retracted along the first direction. The pressure sensor 108 is inductively connected to the first guide wheel 106 to sense the force of the first guide wheel 106 acting on the workpiece along the first direction.

[0050] The pressure sensor 108 is used to sense the interaction force between the first guide wheel 106 and the display screen along the first direction to protect the display screen from being crushed. It is generally set that when the force sensed by the pressure sensor 108 reaches a preset value, the first push member 103 stops moving; and the first guide wheel 106 is elastically arranged along the first direction, which can play a buffering role with the force applied to the display screen along the first direction to prevent hard contact from damaging the display screen.

[0051] Therefore, when the first pushing member 103 pushes the display screen along the first direction to a state of just contacting the first reference member 102, the force value sensed by the pressure sensor 108 has not yet reached the preset value, which is determined according to needs and is generally smaller than the maximum force value allowed by the display screen. The first pushing member 103 continues to move, the first guide wheel 106 is gradually elastically compressed, and the display screen is gradually straightened until the force value sensed by the pressure sensor 108 reaches the preset value, at which time the first pushing member 103 stops moving, and the positioning of the display screen along the first direction is completed.

[0052] Among them, regarding the elastic setting of the first guide wheel 106, the first guide wheel 106 and the first pushing member 103 can be directly elastically connected along the first direction using an elastic member, or an intermediate member can be used for indirect elastic connection. In the embodiment of the present application, the first guide wheel 106 is set on the mounting block 114, and the mounting block 114 is elastically connected to the first pushing member 103 along the first direction as an example. This is more convenient for structural setting. At the same time, the pressure sensor 108 is set on the first pushing member 103 and can be sensed by the mounting block 114. When the first guide wheel 106 interacts with the display screen to make the mounting block 114 move along the first direction and sensed by the pressure sensor 108, the first pushing member 103 stops moving.

[0053] Of course, since the force is mutual, the pressure sensor 108 can be arranged on the first reference member 102 in cooperation with the first guide wheel 106 that can be elastically extended along the first direction, and the effect is the same, which will not be elaborated.

[0054] Similarly, a pressure sensor 108 may be provided on the second pushing member 105 or the second reference member 104 in combination with a second guide wheel 107 that can be elastically retracted along the second direction. The specific configuration is the same as above and will not be described in detail.

[0055] See also Figure 1 Furthermore, the table surface of the carrier 101 is concavely provided with a first avoidance groove 1011 along the first direction, and the first guide wheel 106 provided on the first push member 103 can move along the first direction in the first avoidance groove 1011. In the embodiment of the present application, a display screen is placed on the table surface of the carrier 101 as an example. Therefore, the first guide wheel 106 moves along the first direction in the first avoidance groove 1011 to act on the display screen, which can avoid interference with the carrier 101 and can fully and stably act on the display screen, which helps to improve the implementation of the pushing action and improve the positioning efficiency.

[0056] Similarly, the table surface of the carrier 101 may also be recessed with a second avoidance groove 1012 along the second direction, and the second guide wheel 107 disposed on the second push member 105 may move in the second avoidance groove 1012 along the second direction. The specific effect is the same as above and will not be repeated.

[0057] See also Figure 1 It can be understood that the surface of the carrier 101 can also be provided with adsorption holes 1013 that can be used for vacuum adsorption of the display screen. When the first direction and the second direction of the display screen are positioned, the adsorption holes 1013 of the carrier 101 are adsorbed on the display screen to fix the display screen on the surface of the carrier 101, so as to increase the stability of the display screen and facilitate subsequent repair operations.

[0058] It should be noted that the positioning mechanism 10 in the embodiment of the present application can be used for positioning display screens of various sizes. It is not difficult to know from the above-mentioned settings that any display screen whose size is smaller than the table size of the carrier 101 can be applicable to the positioning mechanism 10 in the embodiment of the present application. Therefore, the adsorption holes 1013 arranged on the carrier 101 in the embodiment of the present application take multiple groups with different adsorption ranges as an example. Each group of adsorption holes 1013 can be adsorbed on a display screen of one size. Of course, the settings of different groups of adsorption holes 1013 can have an overlapping relationship. For example, a group of adsorption holes 1013 with a smaller adsorption range can be a component of a group of adsorption holes 1013 with a larger adsorption range.

[0059] See also Figure 1 and Figure 5 Furthermore, the positioning mechanism 10 in any of the above embodiments may also include a lighting component 109 , which may be movably disposed on one side of the carrier 101 and may be electrically connected to a workpiece carried by the carrier 101 .

[0060] The lighting assembly 109 is used to connect the display screen positioned on the carrier 101 to power the display screen to assist in display repair of the display screen. The lighting assembly 109 can be moved to connect the display screen to power when needed. When the display screen does not need to be connected to power, it can be moved to one side of the carrier 101 to wait to avoid affecting other operations of the carrier 101. Of course, the specific movement and setting of the lighting assembly 109 and the side of the carrier 101 on which it is specifically set are determined according to needs, without limitation, and can meet the functional requirements.

[0061] See also Figure 5 In the above embodiment, the lighting component 109 is arranged on the side of the corresponding second reference member 104 of the carrier 101, and the lighting component 109 includes a carrier 1091 and a lighting member 1092. The carrier 1091 is movably arranged along the first direction, and the lighting member 1092 is arranged on the carrier 1091 and is movable along the second direction.

[0062] The embodiment of the present application takes the lighting component 109 being arranged on the corresponding second reference member 104 side of the carrier 101 as an example. Of course, the lighting component 109 can also be arranged on the corresponding first reference member 102 side of the carrier 101. Compared with the first push member 103 and the second push member 105, the positions of the first reference member 102 and the second reference member 104 are relatively stable. Therefore, the movable lighting component 109 can reduce the influence of mobile interference. At the same time, the first reference member 102 and the second reference member 104 are used as positioning references. After the display screen is positioned and matched with the first reference member 102 and the second reference member 104, the position of the display screen can be accurately fixed, so that power can be connected. Therefore, the lighting component 109 is arranged on the corresponding first reference member 102 side or the corresponding second reference member 104 side of the carrier 101, which is also helpful for power connection. Of course, the power connection part of the display screen is also placed close to the lighting component 109 side.

[0063] Among them, the carrier 1091 serves as a supporting structure for the lighting component 1092, and the carrier 1091 is movably arranged along the first direction relative to the carrier 101, so as to adjust the position of the lighting component 1092 along the first direction for power connection according to different display screen sizes, that is, different power connection locations of the display screens.

[0064] The lighting component 1092 is a component that is electrically connected to the display screen. The lighting component 1092 is movably arranged on the carrier 1091 along the second direction, and can move closer to or away from the carrier 101 along the second direction. When the display screen needs to be electrically connected, the lighting component 1092 is controlled to move closer to the carrier 101 until it is electrically connected to the display screen; when the display screen does not need to be electrically connected, the lighting component 1092 is controlled to move away from the carrier 101, so as to avoid affecting other work in the area of ​​the carrier 101.

[0065] Further, a third direction is defined, denoted as Z, and the third direction is perpendicular to the table surface of the carrier 101. The lighting element 1092 in the above embodiment can also be movably arranged along the third direction. That is, in the embodiment of the present application, the first direction, the second direction and the third direction are respectively perpendicular to each other, and it can be understood that the lighting element 1092 can be adjusted along the first direction, the second direction and the third direction respectively, so as to realize that the lighting element 1092 can be used for accurate power connection of display screens of different sizes.

[0066] The second reference member 104 in the above embodiment is fixedly arranged relative to the carrier 1091 along the first direction, and is movably arranged relative to the carrier 1091 along the second direction. Considering that in actual use, the power connection parts of display screens of different sizes are different, that is, for display screens of different sizes, the carrier 1091 needs to be adjusted accordingly along the first direction, and the second reference member 104 is fixedly arranged relative to the carrier 1091 along the first direction, which can effectively avoid interference between the carrier 1091 and the lighting member 1092 and the second reference member 104 during the adjustment process along the first direction, and also facilitate synchronous control of movement. At the same time, the second reference member 104 is movably arranged relative to the carrier 1091 along the second direction, which can be used as a positioning reference in the second direction to press against the display screen. It can be understood that when the second reference member 104 is needed to position the display screen, the second reference member 104 is controlled to move close to the carrier 101 to the reference position along the second direction; when the second reference member 104 is not needed to position the display screen, the second reference member 104 is controlled to move away from the carrier 101 along the second direction.

[0067] See also Figures 1 to 6Specifically, the positioning mechanism 10 in the above embodiment may also include a base 110, and the carrier 101, the first reference member 102, the first pushing member 103, the second reference member 104, the second pushing member 105 and the carrier 1091 of the lighting component 109 are respectively arranged on the base 110; the base 110 serves as a supporting structure for each component to help improve the structural coordination stability between the components.

[0068] The positioning mechanism 10 may further include a first driving member 111, which is disposed on the base 110 and is drivingly connected to the first pushing member 103, and can drive the first pushing member 103 to move along the first direction; the positioning mechanism 10 may further include a second driving member 112, which is disposed on the base 110 and is drivingly connected to the second pushing member 105, and can drive the second pushing member 105 to move along the second direction; the positioning mechanism 10 may further include a third driving member 113 disposed on the base 110, which is drivingly connected to the second reference member 104 and the carrier 1091 of the lighting component 109, and can drive the second reference member 104 and the carrier 1091 of the lighting component 109 to move synchronously along the first direction.

[0069] In the embodiment of the present application, the movement of the first push member 103 along the first direction, the movement of the second push member 105 along the second direction, and the synchronous movement of the second reference member 104 and the lighting assembly 109 along the first direction are respectively controlled by driving members, so as to automatically coordinate and operate, thereby improving the working efficiency of the positioning mechanism 10. The first driving member 111, the second driving member 112, and the third driving member 113 can be any driving member that meets the corresponding needs without limitation.

[0070] The second reference member 104 may include a reference portion 1041 and a first driving portion 1042, wherein the reference portion 1041 and the first driving portion 1042 are driven and connected along the second direction, and the first driving portion 1042 is driven and connected to the third driving member 113 along the first direction, and the third driving member 113 may drive the first driving portion 1042 and the reference portion 1041 to move synchronously along the first direction.

[0071] The third driving member 113 can drive the second reference member 104 to move as a whole along the first direction. Specifically, taking the example that the third driving member 113 is directly or indirectly driven and connected to the first driving part 1042, the first driving part 1042 and the reference part 1041 are relatively fixedly connected along the first direction. In this way, the third driving member 113 drives the first driving part 1042 to move along the first direction, and the first driving part 1042 and the reference part 1041 move synchronously to adjust the position of the second reference member 104 along the first direction, so that the second reference member 104 can be used for positioning display screens of different sizes.

[0072] It should be noted that the third driving member 113 and the second reference member 104 can be set in multiple groups, taking two groups as an example, and are arranged at intervals along the first direction. When used for positioning a larger-sized display screen, the two groups of driving members are controlled to increase the moving distance between the corresponding two groups of second reference members 104 along the first direction; similarly, when used for positioning a smaller-sized display screen, the two groups of driving members are controlled to reduce the moving distance between the corresponding two groups of second reference members 104 along the first direction.

[0073] The lighting component 109 may also include a second driving unit 1093 and a third driving unit 1094. The third driving member 113 is connected to the second driving unit 1093 for driving along the first direction. The second driving unit 1093 drives the third driving unit 1094 and the lighting component 1092 to move synchronously along the second direction. The third driving unit 1094 drives the lighting component 1092 to move along the third direction. The third driving member 113 drives the second driving unit 1093 to move in the first direction, and drives the third driving unit 1094 and the lighting component 1092 to move synchronously along the first direction.

[0074] The third driving member 113 can also drive the lighting component 109 to move along the first direction as a whole. Specifically, taking the third driving member 113 being directly or indirectly driven and connected to the second driving part 1093 as an example, the lighting component 1092 and the third driving part 1094 are relatively fixedly connected relative to the second driving part 1093 along the first direction. In this way, the third driving member 113 drives the second driving part 1093 to move along the first direction, and the third driving part 1094 and the lighting component 1092 move synchronously. Similarly, the second driving part 1093 is directly or indirectly driven and connected to the third driving part 1094, and the lighting component 1092 and the third driving part 1094 are relatively fixedly connected along the second direction. The second driving part 1093 drives the third driving part 1094 to move along the second direction, and the lighting component 1092 moves synchronously. Therefore, the lighting component 1092 can be driven and controlled in the first direction, the second direction and the third direction respectively, so as to achieve precise power connection for display screens of different sizes.

[0075] Of course, the display screen generally has two power connection points, so taking two groups of lighting components 109 as an example, each group of lighting components 109 is driven by a third driving component 113. When used for a larger display screen, the two third driving components 113 are controlled to increase the distance between the two lighting components 109, and respectively correspond to the two power connection points of the display screen along the first direction, and then the second driving part 1093 and the third driving part 1094 are controlled to make the lighting component 1092 correspondingly electrically connected to the corresponding power connection parts; similarly, when used for a smaller display screen, the two third driving components 113 are controlled to reduce the distance between the two lighting components 109, and respectively correspond to the two power connection points of the display screen along the first direction, and then the second driving part 1093 and the third driving part 1094 are controlled to make the lighting component 1092 correspondingly electrically connected to the corresponding power connection parts.

[0076] Considering the actual lighting and positioning use, the positioning process only requires the second reference member 104 to be able to move along the second direction until it can touch the edge of the display screen, and the implementation conditions are simple. Therefore, each group of lighting components 109 and a group of second reference members 104 are relatively fixed along the first direction and driven and connected to a third driving member 113, which can not only optimize the structural space, but also make the driving control more efficient.

[0077] See also Figure 6 It should also be noted that in actual lighting and positioning use, a display screen of one size is often used in batches. Therefore, the target positions of the lighting component 109 and the second reference member 104 moving along the first direction are relatively fixed. Therefore, the embodiment of the present application may also be provided with a sensing component 115 for feedback of the driving of the third driving member 113 along the first direction. For example, the sensing member 1151 of the sensing component 115 is relatively fixedly connected to the lighting component 109 along the first direction, and the sensing member 1152 of the sensing component 115 is disposed on the base 110. When the sensing member 1151 moves to cooperate with the sensing member 1152 in induction, the corresponding third driving member 113 stops driving. At this time, the lighting component 1092 of the lighting component 109 is opposite to the corresponding power connection part of the display screen along the second direction. Such a configuration can help improve the efficiency of automated operation.

[0078] Of course, the number and location of the sensor components 1152 are determined according to actual needs without any specific restrictions. Similarly, the movement control of the first push member 103 and the second push member 105 may also be assisted by the sensor component 115. The application settings of the sensor component 115 are conventional settings in this field and will not be elaborated on.

[0079] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
