[0020] Figure 1 This is a schematic diagram of the structure of the mobile detection and positioning base plate device of the present invention, with the detection plate located at the detection position. Figure 2 This is a schematic diagram of the structure of a mobile detection and positioning substrate device of the present invention, with the detection plate located at the material picking position; Figure 3 This is a schematic diagram of the structure of a mobile detection and positioning base plate device of the present invention in a maintenance state; Figure 4 This is a schematic diagram of the positioning mechanism of a mobile detection and positioning substrate device according to the present invention; Figure 5 This is a schematic diagram of the structure of the maintenance cylinder of the mobile detection and positioning base plate device of this utility model in the extended state, as shown. Figure 1-5 As shown, a preferred embodiment of a mobile detection and positioning substrate device is illustrated, comprising: a base 3, on which a detection plate 2, a detection mechanism 6, and a driving mechanism 5 are mounted; the detection plate 2 is used to place the substrate and has a detection position and a picking position, and the substrate has a positioning mechanism 4 for positioning the perimeter of the substrate; the detection mechanism 6 is disposed at the detection position for detecting the placement posture of the substrate; the driving mechanism 5 is connected to the detection plate 2 for driving the detection plate 2 to move along a first direction, so that the detection plate 2 moves to the detection position or the picking position.

[0021] In this application, the external substrate feeding mechanism places the substrate on the detection plate 2 at the detection position, the positioning mechanism 4 positions the substrate around its perimeter, and the detection mechanism 6 detects the placement posture of the substrate. After the detection is completed, if it is qualified, the driving mechanism 5 drives the detection plate 2 to move along the first direction to the picking position, and the external gripping mechanism picks up the substrate and installs it at the module assembly station. By integrating the detection, positioning and moving functions of the substrate into one device, the number of independent workstations is reduced, work efficiency is improved, space is saved and production capacity is increased.

[0022] Furthermore, as a preferred embodiment, the first direction is the length direction of the base 3.

[0023] Furthermore, in a preferred embodiment, the detection plate 2 includes a base plate 21 and a pad 22 connected to the top of the base plate 21 for placing the substrate; the positioning mechanism 4 includes two positioning plates 41, two positioning blocks 43, and two driving members. The two positioning plates 41 are respectively located on two adjacent sides of the pad 22 for limiting engagement with two adjacent sides of the substrate. The two positioning blocks are respectively disposed opposite to the two positioning plates 41. The two driving members are respectively connected to the two positioning blocks 43 for driving the two positioning blocks 43 to move toward the two positioning plates 41 to limit engagement with the other two adjacent sides of the substrate. Specifically, the substrate is placed on the pad 22. The two positioning plates 41 first limit the two adjacent sides of the substrate. Then, the two driving members drive the two positioning blocks 43 to move toward the two positioning plates 41 to limit the other two adjacent sides of the substrate, thereby achieving positioning of the substrate in the horizontal plane for subsequent detection operations.

[0024] In this application, the positioning plate 41 and the positioning block 43 work together to accurately position the substrate in the horizontal plane, ensuring the consistency of the substrate gripping position and improving the accuracy of substrate installation.

[0025] Furthermore, in a preferred embodiment, the driving component is a positioning cylinder 42 mounted on the base plate 21. During the positioning process, the positioning cylinder 42 acts as the driving component, its movable end pushing the positioning block 43 towards the positioning plate 41 to complete the limiting positioning of the corresponding edge of the substrate. After positioning, the positioning cylinder 42 can maintain its current state or be reset as needed to facilitate subsequent movement and gripping of the substrate. The positioning cylinder 42 has a simple structure, stable power output, and can reliably drive the positioning block 43 to move, thereby achieving the positioning of the substrate. It is also relatively low in cost and easy to maintain and replace.

[0026] Furthermore, as a preferred embodiment, the pad 22 is made of plastic. The plastic pad 22 can prevent scratches on the substrate during substrate positioning, protect the surface quality of the substrate, and improve the product yield.

[0027] Furthermore, in a preferred embodiment, a detection hole 23 is provided through the bottom of the detection plate 2; the orientation is that of the front and back sides of the substrate, and the substrate is an arc-shaped plate; the detection mechanism 6 includes a distance sensor 61. When the detection plate 2 moves to the detection position, the distance sensor 61 is located directly below the detection hole 23 and facing the detection hole 23. When the detection plate 2 moves to the detection position, the distance sensor 61 is located directly below the detection hole 23. Since the substrate is an arc-shaped plate, if the front and back sides are correctly placed, the distance between the lower surface of the substrate and the sensor measured by the distance sensor 61 is the standard value; if the front and back sides are reversed, the measured distance does not conform to the standard value, and the distance sensor 61 will send a signal feedback to indicate an error.

[0028] Furthermore, in a preferred embodiment, the detection mechanism 6 also includes a bracket 62, which is mounted on the base 3. The distance sensor 61 is a laser distance sensor 61, which is also mounted on the bracket 62. When the detection plate 2 moves to the detection position, the laser distance sensor 61 mounted on the bracket 62 measures the distance to the lower surface of the substrate through the detection hole 23. The bracket 62 provides a stable mounting position for the laser distance sensor 61, ensuring the accuracy of the measurement.

[0029] Furthermore, in a preferred embodiment, the drive mechanism 5 includes a linear slide 52, which is connected to the detection plate 2 for driving the detection plate 2 to move along a first direction. After receiving a control signal, the linear slide 52 drives the detection plate 2 to move along the first direction, realizing the switching of the detection plate 2 between the detection position and the material picking position. The linear slide 52 moves smoothly and has high positioning accuracy, which can accurately control the moving distance and position of the detection plate 2, ensuring the stability and reliability of the device operation.

[0030] Furthermore, in a preferred embodiment, the drive mechanism 5 also includes a lifting cylinder 51, which is mounted on the slide of the linear slide 52. The output end of the lifting cylinder 51 is connected to the bottom of the detection plate 2, and is used to drive the detection plate 2 to rise and fall. When it is necessary to adjust the height of the detection plate 2, the lifting cylinder 51 receives a control signal, and its output end extends and retracts to drive the detection plate 2 to rise and fall. For example, when placing or gripping a substrate, the height of the detection plate 2 can be adjusted by the lifting cylinder 51 to adapt to different operational requirements, increasing the vertical freedom of movement of the detection plate 2, enabling the device to better adapt to the operational requirements of substrates of different specifications, and improving the versatility and flexibility of the device.

[0031] Furthermore, as a preferred embodiment, the device also includes a frame 1, which is arranged along a first direction. The base 3 is slidably mounted on the frame 1 along the first direction. A maintenance cylinder 7 is mounted on the frame 1 and is kinetically connected to the base 3 to drive the base 3 to slide along the first direction. The maintenance cylinder 7 allows the base 3 to be easily extended when maintenance is required, providing sufficient operating space for maintenance personnel, improving the maintainability of the device, and reducing maintenance time and costs.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
