[0043] Reference Figures 1-3 According to an embodiment of the present invention, a display screen precision alignment and repair platform includes:

[0044] Base 100;

[0045] A positioning mechanism 200 is provided on the base 100. The positioning mechanism 200 includes a first power component 210 and a stage 220. The first power component 210 is used to drive the stage 220 to move along the Z-axis.

[0046] Pressure sensor 300 is mounted on stage 220;

[0047] A crimping mechanism 400 is provided on the base 100. The crimping mechanism 400 includes a second power component 410 and a crimping head 420. The second power component 410 drives the crimping head 420 to move along the Z-axis direction.

[0048] An angle adjustment mechanism 500 is provided on the crimping head 420. The angle adjustment mechanism 500 includes a third power component 510 and a fourth power component 520. The third power component 510 drives the fourth power component 520 and the crimping head 420 to rotate around the X-axis. The fourth power component 520 drives the crimping head 420 to rotate around the Y-axis. The third power component 510 drives the crimping head 420 to rotate around the X-axis.

[0049] The camera mechanism 600 is located on the base 100 and is used to determine the pin position of the crimp connector 420.

[0050] According to an embodiment of the present invention, by such a configuration, at least the following effects can be achieved: the stage 220 is used to place the display screen product; the third power component 510 of the angle adjustment mechanism 500 adjusts the X and Y axial angles of the crimping connector 420 so that the crimping angle of the crimping connector 420 corresponds to the connector of the product; the position of the pins of the crimping connector 420 is determined by the imaging mechanism 600; the position of the crimping connector 420 is determined first and it is judged whether it matches the connector pins before proceeding with subsequent work to prevent crimping errors that could damage the product or the crimping connector 420; the first power component 210 drives the stage 2... The device moves upward, raising the stage 220 to a certain height, causing the product and the crimping connector 420 to come into contact for coarse positioning. Then, the second power unit 410 drives the crimping connector 420 closer to the stage 220 for fine positioning. After successful crimping, the crimping connector 420 is connected to the product. The pressure sensor 300 is used to determine the pressure of the crimping connector 420 during initial and fine positioning to prevent the needle from being crushed. There is a pre-pressing action before crimping. This pressure is converted from an electrical signal to an analog signal by the pressure sensor 300, which can detect the current pressure value and determine whether the pressure value is appropriate.

[0051] Understandably, the crimp connector 420 is a crimping module. The PCB board serves as the substrate, the copper wires serve as the transmission lines, and one end of the wires consists of a crimp head (i.e., pins) composed of many copper pins. These pins act as the transmitters that connect and illuminate the product.

[0052] It is understandable that the X, Y, and Z axes are any axes that do not coincide or are parallel to each other.

[0053] In some embodiments, the positioning mechanism 200 further includes a fifth power component 230, which drives the stage 220 to move along the X and Y axes. The fifth power component 230 is a multi-axis parallel motion mechanism that achieves linear motion along both the X and Y axes through the parallel motion of multiple linear moving axes, resulting in high control precision. After the imaging mechanism 600 determines the position of the pins of the crimp connector 420, the fifth power component 230 adjusts the position of the stage 220 so that the pins of the product can align with the pins of the crimp connector 420.

[0054] Furthermore, the fifth power assembly 230 also includes a Z-axis rotary motion motor, which can drive the stage 220 to rotate along the Z-axis direction, further adjusting the position of the stage 220 to enable better product alignment.

[0055] In some embodiments, the third power assembly 510 includes:

[0056] The first support 511 is driven to move along the Z-axis by the second power component 410.

[0057] A rotating disk 512 is rotatably mounted on a first support 511. The rotating disk 512 is equipped with an adjusting rod. A fourth power assembly 520 and a crimp connector 420 are mounted on the rotating disk 512.

[0058] The first adjusting member 513 is disposed on the first support 511 and can move along the first support 511 in the Z direction. The first adjusting member 513 abuts against the adjusting rod and can drive the rotating disk 512 to rotate.

[0059] In this configuration, the first bracket 511 supports the fourth power mechanism and the crimp connector 420. The second power assembly 410 can drive the first bracket 511 to move along the Z-axis, so that the second power assembly 410 can adjust the position of the crimp connector 420. The rotating disk 512 is rotatably mounted on the first bracket 511. Through the movement of the first adjusting member 513 along the Z-direction, the rotating disk 512 can rotate clockwise or counterclockwise to adjust the angle in the X-direction to adapt to the angle of the product pins.

[0060] Furthermore, the third power assembly 510 also includes an elastic element 514. The elastic element 514 and the first adjusting element 513 are respectively disposed on both sides of the adjusting rod. The elastic element 514 is driven by elastic force to rotate the adjusting rod towards the first adjusting element 513. Through the combination of the elastic element 514 and the first adjusting element 513, the rotating disk 512 can rotate in both directions.

[0061] Furthermore, the first adjusting element 513 is a screw with high thread precision, which can control the adjustment angle of the pressure connector 420 with high precision, adapt to small deviations, and facilitate use.

[0062] In some embodiments, the fourth power assembly 520 includes:

[0063] The second support 521 is driven to rotate around the X-axis by the third power component 510.

[0064] The third bracket 522 is rotatably mounted on the second bracket 521, and the crimp connector 420 is mounted on the third bracket 522;

[0065] The second adjusting component 523 is used to adjust the angle of the third support 522.

[0066] In this configuration, the third bracket 522 can rotate clockwise or counterclockwise by moving the second adjustment member 523 along the Z direction, adjusting the angle in the Y direction to suit the angle of the product pins.

[0067] Furthermore, one end of the second adjusting member 523 is threadedly connected to the second bracket 521, and the other end is movably connected to the third bracket 522. When the second adjusting member 523 moves up and down, it can adjust the angle of the third bracket 522, thereby changing the angle of the pressure joint 420.

[0068] In some embodiments, a rangefinder 700 is also included, which is disposed above the stage 220. The rangefinder 700 is used to check the flatness of the stage 220. Simply put, the laser rangefinder 700 measures point-to-point distances. Here, it is used to calibrate the flatness of the platform, requiring high precision to ensure accurate product placement and facilitate subsequent operations.

[0069] In some embodiments, the stage 220 is made of ceramic. The stage 220 includes a vacuum platform and a ceramic platform. The vacuum stage is an aluminum alloy stage with three negative pressure channels. The ceramic stage is a porous ceramic platform, sintered, which can be used as an adsorption platform and is embedded in the aluminum alloy stage.

[0070] In some embodiments, the stage 220 is provided with multiple air ports for adsorbing products. The air ports are connected to a negative pressure valve, which enables the products to be adsorbed onto the stage 220 and prevents the products from shaking.

[0071] In some embodiments, the first power component 210 is a linear screw module, and the second power component 410 is a linear screw module. High screw transmission precision: The greatest advantage of ball screws lies in their high precision, which greatly improves transmission efficiency and reduces slippage problems. Therefore, their linear motion precision is higher than that of sliding screws, and they perform better in terms of transmission precision stability. High load-bearing capacity: The internal structure of a ball screw incorporates balls or other rolling elements. This structure not only improves force transmission but also absorbs larger impact loads and torques. Therefore, ball screws can withstand greater loads and have a longer service life. Smooth motion: Compared to sliding screws, ball screws have smoother motion and lower friction, resulting in less vibration and shock during operation.

[0072] In some embodiments, the imaging mechanism 600 further includes a seventh power component, which drives the imaging mechanism 600 to move along the Y direction, so that the imaging mechanism 600 aligns with the pressure joint 420 and improves the imaging accuracy.

[0073] The above are merely preferred embodiments of the present invention. The present invention is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention, as long as they achieve the same technical effects, should be included within the scope of protection disclosed in the present invention. Within the scope of protection of the present invention, the technical solutions and / or implementation methods can have various modifications and variations.
