Technical Field

[0001] This utility model patent relates to the field of LCD screen inspection technology, and mainly to a device that can change the human eye's line of sight for inspection. Background Technology

[0002] LCD screens are increasingly used in the electronics industry today, with a wide range of applications, including digital products, automotive parts, and machine tools. The illumination inspection process is essential in LCD screen production, but the volume of this process is enormous during mass production. Typically, the LCD screen is fixed on a bracket, and the human eye inspects the screen's luminous surface in four directions (up, down, left, and right). However, it's difficult to change the screen's angle, forcing the user to repeatedly rotate their neck, which can cause neck muscle strain over time. To address this, we propose a device that allows for changing the user's line of sight during inspection. Utility Model Content

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0024] For an example, please refer to... Figure 1-4 A device for changing the line of sight for human eye inspection includes a frame 10 and a support device 20. The support device 20 includes a fixed cylinder 21 slidably connected to one side of the top of the frame 10, a rotating ball 22 rotatably connected to the top of the fixed cylinder 21, a base plate 23 connected to the top of the rotating ball 22, and a support plate 24 connected to the top of the base plate 23. The top of the support plate 24 is connected to a product body 30, and a plurality of limiting blocks 25 are connected to the top of the support plate 24. The limiting blocks 25 are located outside the product body 30, and a terminal 31 is connected to one side of the product body 30.

[0025] The fixed cylinder 21 has a threaded hole on one side of its top. The fixed cylinder 21 is connected to the adjustment assembly 70. The adjustment assembly 70 includes a threaded rod 71 connected to the threaded hole and a pressing block 72 rotatably connected to one side of the threaded rod 71. The pressing block 72 cooperates with the rotating ball 22.

[0026] The base plate 23 is connected to the top two sides of the needle mold 40, and the needle mold 40 is connected to the terminal 31.

[0027] It should be noted that, in this embodiment, the operator rotates the base plate 23 to rotate the rotating ball 22, thereby adjusting the position of the product body 30. The rotation of the threaded rod 71 causes the threaded rod 71 and the extrusion block 72 to move. Since the extrusion block 72 is in contact with the rotating ball 22, the extrusion block 72 is prevented from rotating with the threaded rod 71. By controlling the extrusion force of the extrusion block 72, the ease of rotation of the rotating ball 22 is controlled. The limiting block 25 is set according to the shape of the product body 30, thereby limiting the position of the product body 30.

[0028] For an example, please refer to... Figure 1 The bottom side of the frame 10 is connected to the signal test box 100, one side of the signal test box 100 is connected to the controller 80 via a wire, and one side of the signal test box 100 is connected to the needle mold 40 via a ribbon cable.

[0029] It should be noted that, in this embodiment, the signal test box 100 is used for program input, and the controller 80 is provided with multiple control buttons. The control buttons represent different instructions, causing the product body 30 to display different images. The operator sends instructions to the signal test box 100 through the controller 80, and the signal test box 100 sends signals to the needle mold 40 through a ribbon cable. The needle mold 40 causes the product body 30 to display images through the terminal 31.

[0030] For an example, please refer to... Figure 1 The top two sides of the base plate 23 are connected to circuit start switches 60, and the two sides of the base plate 23 are rotatably connected to magnetic rotary anti-fool switches 50, which cooperate with the circuit start switches 60.

[0031] It should be noted that, in the embodiment, the circuit start switch 60 facilitates the control of the circuit start and stop. When the magnetic rotary anti-fool switch 50 is rotated to contact the circuit start switch 60, the circuit start switch 60 is turned on, and at the same time, it can control the cover plate of the needle mold 40 to be fixed, preventing the needle mold 40 from being disconnected from the terminal 31. When the magnetic rotary anti-fool switch 50 is rotated to the end away from the circuit start switch 60, the circuit start switch 60 is turned off, and at the same time, the cover plate of the needle mold 40 can be opened.

[0032] For an example, please refer to... Figure 3-4 A C-shaped slider 211 is fixed to the bottom of the fixed cylinder 21;

[0033] The frame 10 has an annular groove 12 on one side of its top, and the groove of the annular groove 12 is slidably connected to the C-shaped slider 211.

[0034] It should be noted that, in the embodiment, the C-shaped slider 211 cooperates with the annular groove 12 to improve the stability of the fixed cylinder 21 and facilitate the sliding of the fixed cylinder 21 along the groove of the annular groove 12.

[0035] For an example, please refer to... Figure 1-2 The frame 10 has support rods fixed on both sides of the top, and magnets 11 are fixed on the top of the support rods.

[0036] Iron blocks 231 are fixed on both sides of the bottom of the base plate 23, and the iron blocks 231 cooperate with the magnet 11.

[0037] It should be noted that, in the embodiment, the iron block 231 cooperates with the magnet 11 to facilitate fixing the base plate 23 and prevent the base plate 23 from shaking when the device is moved.

[0038] For an example, please refer to... Figure 2 and Figure 4 The top side of the C-shaped slider 211 is connected by a bolt 90, and the side of the bolt 90 is rotatably connected to a friction plate 91, which is engaged with the groove of the annular groove 12.

[0039] It should be noted that, in the embodiment, the rotation of the bolt 90 causes the bolt 90 and the friction plate 91 to move, thereby adjusting the force of the friction plate 91 pressing against the annular groove 12. The friction plate 91 maintains a constant angle due to gravity, and the pressing of the friction plate 91 against the annular groove 12 facilitates control over the ease of sliding the C-shaped slider 211.

[0040] For an example, please refer to... Figure 3 The support plate 24 has multiple product loading and unloading holes 241 on one side.

[0041] It should be noted that, in this embodiment, the product placement hole 241 facilitates the placement and picking up of products by staff, avoiding contact between manual hands and the support plate 24.

[0042] The specific operation method of this utility model is as follows:

[0043] The aforementioned device for changing the line of sight for human eye inspection moves the threaded rod 71 and the extrusion block 72 by rotating the threaded rod 71, thereby controlling the extrusion force of the extrusion block 72 and allowing the operator to adjust the difficulty of rotating the rotating ball 22 according to their own preferences.

[0044] Then, the two product bodies 30 are placed on the support plate 24, and the terminal 31 is connected to the needle mold 40. Then, the magnetic rotary foolproof switch 50 is rotated until it contacts the circuit start switch 60. At this time, the circuit start switch 60 is turned on and can control the cover plate of the needle mold 40 to be fixed. The operator sends a command to the signal test box 100 through the controller 80. The signal test box 100 sends a signal to the needle mold 40 through the ribbon cable. The needle mold 40 displays the screen on the product body 30 through the terminal 31. Then, the operator rotates the base plate 23 to rotate the rotating ball 22, thereby adjusting the position of the product body 30.

[0045] The embodiments described above merely illustrate the implementation methods of this application. However, those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
