[0002] As a vital tool for information dissemination in modern society, displays can present various information such as images, text, and videos in an intuitive and vivid way. Whether in home entertainment, commercial advertising, education and training, or industrial control, displays play an indispensable role. To ensure the optimal performance of displays, testing is necessary at each stage of the production process.

[0003] Currently, during display screen testing, the rotation angle of the display screen is adjusted manually on the testing platform to ensure that the spatial position of the display screen meets the testing requirements. However, manual adjustment not only increases the risk of damage and wear to the display screen, but also takes a long time to rotate the display screen, resulting in low testing efficiency. Utility Model Content

[0004] In view of this, the present invention provides a workstation switching mechanism and a display screen testing device to solve the problems of low testing efficiency caused by manual operation, which not only increases the risk of damage to the display screen from bumps and scratches, but also requires a long time to rotate the display screen.

The second connecting part is slidably connected to the second slide rail, and the angle between the movement direction of the second connecting part and the extension direction of the second slide rail is an acute angle.

[0009] The sliding member has a rotational state in which it moves in a first direction under the action of an external force to drive the rotating member to rotate.

[0010] Optionally, the above-mentioned workstation switching mechanism further includes a rotary drive component, which is connected to the sliding component and can drive the sliding component to move in a first direction.

[0011] Optionally, the above-mentioned workstation switching mechanism further includes a slide rod, wherein the rotating component has a through hole, the through hole is sleeved on the outer periphery of the slide rod, and the through hole is slidably connected to the slide rod, and the two ends of the slide rod extending out of the through hole are respectively fixedly connected to the rotating component drive component and the sliding component.

[0012] Optionally, in the above-mentioned workstation switching mechanism, the rotating component is further provided with a third slide rail. The third slide rail and the second slide rail are both grooves, and the third slide rail and the second slide rail are connected. The extension direction of the third slide rail is parallel to the extension direction of the first slide rail.

[0013] The second connecting part is a protrusion, and the second connecting part is slidably connected to the second slide rail or the third slide rail;

[0014] In the rotated state, the second connecting part moves from the second slide rail to the third slide rail;

[0015] The sliding member has the ability to move in a second direction opposite to the first direction under the action of an external force, thereby limiting the stationary state of the rotating member.

[0016] Optionally, in the above-mentioned workstation switching mechanism, the second slide rail is connected to the third slide rail to form a chute unit, and multiple chute units are provided, with the multiple chute units connected end to end in sequence;

[0020] Optionally, the above-mentioned workstation switching mechanism further includes a support platform, which is fixedly connected to the rotating component.

[0021] Optionally, in the above-mentioned workstation switching mechanism, the length of the third slide is equal to half the length of the second slide.

[0022] This utility model also includes a display screen testing device, which includes the aforementioned workstation switching mechanism.

[0023] The technical solution provided by this utility model has the following advantages:

[0024] 1. The workstation switching mechanism provided by this utility model includes a base, a rotating component, and a sliding component. The base is provided with a first slide rail. The rotating component is used to support the display screen to be tested. The rotating component is rotatably connected to the base and is provided with a second slide rail. The sliding component has a first connecting part and a second connecting part. The first connecting part is slidably connected to the first slide rail, and the movement direction of the first connecting part is parallel to the extension direction of the first slide rail. The second connecting part is slidably connected to the second slide rail, and the angle between the movement direction of the second connecting part and the extension direction of the second slide rail is an acute angle. The sliding component has a rotational state in which it moves towards a first direction under the action of an external force to drive the rotating component to rotate. By pushing the sliding component, the sliding component moves towards the first direction, thereby driving the first connecting part and the second connecting part to move towards the first direction. Since the angle between the movement direction of the second connecting part and the extension direction of the second slide rail is an acute angle, and the rotating component is rotatably connected to the base, the second connecting part forces the rotating component to rotate while the second connecting part moves towards the first direction, so that the second connecting part continues to move towards the first direction. This workstation switching mechanism eliminates the need for manual contact with the display screen, thus avoiding the risk of damage from bumps and scratches. Furthermore, it eliminates the need for manual rotation of the display screen; simply pushing the sliding component allows for rotation, reducing the time required to rotate the screen and thereby improving testing efficiency.

[0040] Example 1

[0041] The workstation switching mechanism provided in this embodiment includes a base 100, a rotating component 200, and a sliding component 300. The base 100 is provided with a first slide rail 101. The rotating component 200 is used to support the display screen to be tested. The rotating component 200 is rotatably connected to the base 100, and the rotating component 200 is provided with a second slide rail 201. The sliding component 300 has a first connecting part 301 and a second connecting part 302. The first connecting part 301 is slidably connected to the first slide rail 101, and the movement direction of the first connecting part 301 is parallel to the extension direction of the first slide rail 101. The second connecting part 302 is slidably connected to the second slide rail 201, and the angle between the movement direction of the second connecting part 302 and the extension direction of the second slide rail 201 is an acute angle. The sliding component 300 has a rotational state in which it moves toward a first direction under the action of an external force to drive the rotating component 200 to rotate.

[0042] Specifically, the base 100 primarily provides support for the entire structure and installation space for other components. The base 100 can be made of aluminum alloy or other materials. Its specific shape is not limited; it can be cylindrical, cuboid, or other common shapes, such as... Figure 2 As shown, the base 100 is assembled from a rounded rectangular plate and a rectangular column. The lower surface of the rectangular column is fixedly connected to the upper surface of the rounded rectangular plate. The fixing method can be welding, bolting, integral injection molding, or other common fixing methods. The base 100 is provided with a first slide rail 101, which is the sliding path of the first connecting part 301. The first slide rail 101 can be a slide rail or a groove, such as... Figure 2 As shown, a first slide rail 101 is provided on the side of the rectangular column. The first slide rail 101 is a straight groove that communicates with the receiving groove. The extending direction of the first slide rail 101 is parallel to the rotation axis of the rotating component 200. A receiving groove is provided on the upper surface of the rectangular column. The receiving groove provides installation space for the rotating component 200. The rotating component 200 is inserted into the receiving groove, and the outer wall of the rotating component 200 is slidably connected to the inner wall of the receiving groove, thereby allowing the rotating component 200 to rotate relative to the receiving groove. The shape of the receiving groove is adapted to the shape of the rotating component 200. The shape of the rotating component 200 is not specifically limited, such as... Figure 3As shown, the rotating component 200 can be cylindrical, meaning the receiving groove is a circular recess. The base 100 also has a limiting component to prevent the rotating component 200 from detaching from the receiving groove. This limiting component can be an annular baffle. After the rotating component 200 is inserted into the receiving cavity, its upper surface is flush with the upper surface of the rectangular column. The outer ring of the annular baffle is fixedly connected to the upper surface of the rectangular column, and the inner ring of the annular baffle is located above the receiving groove. The inner ring of the arc-shaped baffle is also fixedly connected to the upper surface of the rotating component 200. Due to the limiting effect of the annular baffle, the rotating component 200 is prevented from detaching from the receiving groove. Alternatively, an annular groove can be formed on the inner wall of the receiving groove, and a protrusion can be provided on the rotating component 200. After the rotating component 200 is inserted into the receiving groove, the protrusion simultaneously inserts into the annular groove. The rotating component 200 rotates, causing the protrusion to slide along the annular groove. This method also prevents the rotating component 200 from detaching from the receiving groove. The rotating component 200 has a second slide rail 201 on its side. The second slide rail 201 is the sliding path of the second connecting part 302. The second slide rail 201 can be a slide rail or a slide groove, such as... Figure 3 As shown, a second slide rail 201 is formed on the outer surface of the rotating component 200. The second slide rail 201 is an arc-shaped groove, and the angle between the second slide rail 201 and the rotation axis of the rotating component 200 is an acute angle. The sliding component 300 has a first connecting part 301 and a second connecting part 302. Both the first connecting part 301 and the second connecting part 302 are sliders. The first connecting part 301 is mounted on the first slide rail 101 and is slidably connected to the first slide rail 101, such as... Figure 1 As shown, the first connecting part 301 is inserted into the linear slide groove and slidably connected to the inner wall of the linear slide groove; the second connecting part 302 is installed on the second slide rail 201 and slidably connected to the second slide rail 201, as shown. Figure 2 As shown, the end of the second connecting part 302 is inserted into the arc-shaped groove and slidably connected to the inner wall of the arc-shaped groove. The first connecting part 301 and the second connecting part 302 are both part of the sliding member 300. When the sliding member 300 moves toward the first direction, the first connecting part 301 and the second connecting part 302 also move toward the first direction at the same time. Since the movement direction of the first connecting part 301 is parallel to the extension direction of the straight groove, the first connecting part 301 slides along the extension direction of the second slide 201. Since the angle between the movement direction of the second connecting part 302 and the extension direction of the second slide 201 is an acute angle, the second connecting part 302 will push the second slide 201 to make the second slide 201 rotate, thereby changing the position of the second connecting part 302 on the second slide 201.

[0043] The workstation switching mechanism provided in this embodiment pushes the sliding member 300 to move in a first direction, thereby causing the first connecting part 301 and the second connecting part 302 to move in the first direction. Since the angle between the movement direction of the second connecting part 302 and the extension direction of the second slide rail 201 is an acute angle, and the rotating member 200 is rotatably connected to the base 100, the second connecting part 302 forces the rotating member 200 to rotate while moving in the first direction, so that the second connecting part 302 continues to move in the first direction. This workstation switching mechanism eliminates the need for manual contact with the display screen, thus avoiding the risk of damage from bumps and scratches. Furthermore, it eliminates the need for manual rotation of the display screen; simply pushing the sliding member 300 is sufficient to rotate the display screen, reducing the time required for rotation and improving testing efficiency.

[0044] like Figure 2 and Figure 3 As shown, the workstation switching mechanism provided in this embodiment also includes a rotary drive 401, which is connected to the sliding member 300. The rotary drive 401 is used to drive the sliding member 300 to move in a first direction, which is the extension direction of the rotation axis of the rotary member 200, i.e., the attached... Figure 2 In the vertical direction, the rotary drive 401 can be a button, a robotic arm, or other linear motion equipment, such as a hydraulic cylinder or a linear motor.

[0045] Furthermore, the workstation switching mechanism provided in this embodiment also includes a slide rod 402. The rotating component 200 has a through hole at its center. The shape of the through hole is not limited. In this embodiment, a circular through hole is used. The first slide rail 101 communicates with the through hole. The through hole is sleeved on the outer periphery of the slide rod 402. The slide rod 402 is slidably connected to the through hole, that is, the slide rod 402 can move along the axial direction of the through hole. Both ends of the slide rod 402 extend out of the through hole. The upper end of the slide rod 402 is connected to the rotating drive component 401. A blind hole adapted to the slide rod 402 is opened at the bottom of the receiving groove. The lower end of the slide rod 402 is inserted into the blind hole and slidably connected to the inner wall of the blind hole. The sliding component 300 is assembled from a first connecting part 301, a second connecting part 302, and a third connecting part. The first connecting part 301, the second connecting part 302, and the third connecting part are all rods. The two ends of the first connecting part 301 are respectively connected to the second connecting part 302 and the third connecting part, and the second connecting part 302 and the third connecting part are perpendicular to the first connecting part 301. The first connecting part 301 is inserted into the first slide rail 101, the end of the second connecting part 302 is inserted into the second slide rail 201, and the third connecting part extends into the through hole and is fixedly connected to the outer peripheral side wall of the slide rod 402. By setting the sliding component 300, the slide rod 402, and the rotating component 200 in the receiving groove, the compactness of the equipment is improved, and the aesthetics of the equipment are also improved.

[0046] Furthermore, in the workstation switching mechanism provided in this embodiment, the rotating component 200 is also provided with a third slide rail 202. The third slide rail 202 is also a groove, and the third groove is a straight groove. The third slide rail 202 is connected to the second slide rail 201, and the extension direction of the third slide rail 202 is parallel to the extension direction of the first slide rail 101. The rotation drive component 401 drives the sliding component 300 toward the first direction, so that the second connecting part 302 is slidably connected to the second slide rail 201 until the second connecting part 302 slides from the second slide rail 201 into the third slide rail 202. When the sliding component 300 moves toward the second direction, it drives the first connecting part 301 and the second connecting part 302 to move toward the second direction. At the same time, the second connecting part 302 slides along the third slide rail 202. Since the extension direction of the third slide rail 202 is parallel to the extension direction of the first slide rail 101, the rotating component 200 remains stationary and does not rotate. At this time, a series of display screen tests can be performed, such as... Figure 3 As shown, the second direction is opposite to the first direction, and the second direction is vertically upward.

[0047] Furthermore, in the workstation switching mechanism provided in this embodiment, the second slide rail 201 and the third slide rail 202 are connected to form a slide rail unit. Multiple slide rail units are provided, and the multiple slide rail units are sequentially connected end-to-end, such as... Figure 3 As shown, multiple slide rail units surround the rotation axis of the rotating component 200, and both ends of any one of the second slide rails 201 are connected to two adjacent third slide rails 202 respectively. When the sliding component 300 moves along the second direction, the second connecting part 302 moves from the third slide rail 202 to the next adjacent second slide rail 201. Each slide rail unit corresponds to a rotating station (the angle of the display screen carried on the rotating component 200). By setting multiple slide rails, different display screen stations can be switched, thereby satisfying the testing of the display screen by multiple testing devices.

[0048] Furthermore, the workstation switching mechanism provided in this embodiment also includes a reset drive 500. The reset drive and the rotary drive 401 can be the same or exist separately. The reset drive 500 can also be a hydraulic cylinder, a linear single machine or other linear motion equipment. The reset drive 500 is connected to the sliding member 300, and the reset drive 500 can drive the sliding member 300 to move in the second direction.

[0049] Furthermore, in the workstation switching mechanism provided in this embodiment, the reset drive 500 is an elastic element, such as... Figure 3As shown, the reset drive 500 is a spring. The bottom of the spring is fixedly connected to the bottom of the blind hole, and the top of the spring is fixedly connected to the bottom of the slide rod 402. The spring is located inside the blind hole. When the slide rod 402 moves in the first direction, it compresses the spring to generate a bias force. When the second connecting part 302 enters any of the third slide rails 202, the bias force drives the slide rod 402 to move in the second direction, that is, drives the sliding member 300 to move upward, so that the second connecting part 302 enters the next adjacent second slide rail 201 from the third slide rail 202 to perform the next cycle.

[0050] Furthermore, the workstation switching mechanism provided in this embodiment also includes a support platform 600. The lower surface of the support platform 600 is fixedly connected to the upper surface of the support component. The upper surface of the support platform 600 is used to support the display screen. Multiple display screens can also be set to realize the testing of individual display screens and improve the testing efficiency of the display screens.

[0051] In the workstation switching mechanism provided in this embodiment, the third slide 202 is equal to half the length of the second slide 201, that is, the angle between the third slide 202 and the second slide 201 connected to it is 60°. By rotating the drive component 401, the rotating component 200 can be rotated 60°.

[0052] When switching display screen positions, pressing the rotary drive 401 causes the slide bar 402 to move in the first direction (downward). The slide bar 402 then moves the sliding member 300 in the first direction, simultaneously moving the first connecting part 301 and the second connecting part 302 in the first direction. Since the second connecting part 302 is slidably connected to the second slide rail 201, and the angle between the extension direction of the second slide rail 201 and the movement direction of the second connecting part 302 is acute, the second connecting part 302 pushes the second slide, causing the rotary member 200 to rotate until the second connecting part 302 slides into the third slide rail 202 connected to the second slide rail 201. At this point, the rotary member 200 rotates 60°. The reset drive 500 generates a biasing force. Then, the rotary drive 401 is released, and the slide bar 402 moves in the second direction under the action of the biasing force, so as to drive the first connecting part 301 and the second connecting part 302 to move in the second direction. Since the third slide 202 is parallel to the moving direction of the second connecting part 302, the rotary member 200 is stationary until the second connecting part 302 enters the next second slide 201 connected to the third slide 202, so as to wait for the next press of the rotary drive 401.

[0053] Example 2

[0054] The display screen testing device provided in this embodiment includes the station switching mechanism of embodiment 1. The display screen can be rotated by pressing the rotation drive 401, eliminating the need for manual rotation of the display screen and improving testing efficiency.

[0055] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
