Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display module calibration, in particular to a device for quickly calibrating the angle of a PIN leg of a liquid crystal display module. Background Art

[0002] PIN Leg is a connector between a circuit board and a liquid crystal display, mainly used to achieve electrical connection and signal transmission between the two. In the liquid crystal display module, PIN Leg plays a vital role, which effectively connects various electronic components (such as drive circuit, touch screen controller, etc.) with the liquid crystal display;

[0003] When designing and using PIN legs, the size and shape of the PIN legs should match the size of the connected circuit board and LCD display to ensure good electrical and mechanical compatibility. The spacing of the PIN legs should be moderate to ensure good contact during electrical connection, and no interference or damage will occur during mechanical connection. The PIN legs should have good electrical insulation properties and mechanical strength to ensure stability and safety during long-term operation and use.

[0004] At present, in the production process of PIN legs, the angles of PIN legs may be inconsistent due to various reasons. When the angle of the PIN leg is greater than 90°, it is impossible to directly observe and judge whether the angle of the PIN leg is qualified with the naked eye, and it can only be tested with a protractor. However, the measurement operation of the protractor for PIN leg products is cumbersome and inefficient. Therefore, in order to ensure that the angle of the PIN leg is in a qualified state after the production is completed, this device provides a method for quickly verifying the angle of the PIN leg of the liquid crystal display module. Utility Model Content

[0005] The purpose of the utility model is to provide a device for quickly checking the angle of the PIN leg of a liquid crystal display module in view of the deficiencies of the prior art, so as to solve the above-mentioned technical problems.

[0006] The embodiment of the utility model adopts the following technical scheme: it includes a workbench for calibrating the angle of the PIN legs of the liquid crystal display module and a base for supporting the workbench, the workbench is arranged on the base at an inclination of 45 degrees, the workbench is provided with a PIN angle groove for calibrating the PIN legs of the liquid crystal display module, the base is arranged on a horizontal plane, the interior of the PIN angle groove is smooth and has no burrs, and the workbench is installed on the base by screws.

[0007] Furthermore, the workbench includes a verification slide and a verification slider. The verification slide is arranged on the base at an inclination of 45 degrees. Two verification sliders are provided. The two verification sliders are symmetrically arranged on both sides of the verification slide and are adapted to the inclination angle of the verification slide. A slide groove is formed between the two verification sliders. Two PIN angle grooves are provided on the two verification slides. The shape formed by the slide groove and the two PIN angle grooves is exactly adapted to the product that needs to be verified.

[0008] Furthermore, the upper ends of the two PIN angle grooves are both conically hollowed out, and the upper and lower end sizes of the two PIN angle grooves are set according to the upper and lower limits of the sizes converted from the upper and lower limits of the angle allowable tolerance.

[0009] Furthermore, a buffer elastic pad is provided at the upper end of the base and below the workbench, and the buffer elastic pad is adhesively connected to the upper end of the base.

[0010] Furthermore, the base includes a base plate and a support plate, the base plate is arranged on a horizontal plane, the support plate is arranged on the base plate, and the support plate is inclined at 45 degrees.

[0011] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0012] The utility model, when checking the angle of the PIN leg of the liquid crystal display module, only needs the operator to put down the PIN leg of the liquid crystal display module to be checked from the starting position of the PIN angle groove on the workbench. If the angle of the product is qualified, the liquid crystal display module will directly slide out of the PIN angle groove. If it is unqualified, it will be stuck in the PIN angle groove and will not move. It is taken out and placed at the unqualified position, and the PIN leg angle is subsequently corrected, and then it is checked again, so that the effects of easy operation, fast judgment speed and high accuracy are achieved.

[0013] When the operator calibrates the angle of the PIN leg of the required liquid crystal display module, since the two PIN angle grooves themselves are adapted to the size of the required calibration product, it is inconvenient for the operator to place the required calibration product from the starting points of the two PIN angle grooves, which will affect the efficiency of the operator's calibration. By setting the upper ends of the two PIN angle grooves to be conical hollow, the operator can more conveniently place the PIN leg of the required liquid crystal display module from the starting points of the two PIN angle grooves for calibration when calibrating the angle of the PIN leg of the required liquid crystal display module.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by patients with ordinary skills in the field without making creative work are within the scope of protection of the utility model.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the utility model provides a device for quickly checking the angle of the PIN leg of a liquid crystal display module, comprising a workbench 1 for checking the angle of the PIN leg of the liquid crystal display module and a base 2 for supporting the workbench 1, wherein the workbench 1 is arranged on the base 2 at an inclination of 45 degrees, and the workbench 1 is provided with a PIN angle groove 13 for checking the PIN leg of the liquid crystal display module, the base 2 is arranged on a horizontal plane, the interior of the PIN angle groove 13 is smoothly arranged without burrs, and the workbench 1 is installed on the base 2 by screw fixing.

[0026] When the device calibrates the angle of the PIN leg of the liquid crystal display module, the operator only needs to put the PIN leg of the liquid crystal display module to be calibrated down from the starting position of the PIN angle groove 13 on the workbench 1. If the product angle is qualified, the liquid crystal display module will directly slide out of the PIN angle groove 13. If it is unqualified, it will be stuck in the PIN angle groove 13 and will not move. It will be taken out and placed at the unqualified position, and the PIN leg angle will be re-corrected afterwards, and then it will be calibrated again, thereby achieving the effects of easy operation, fast judgment speed and high accuracy.

[0027] In a further preferred embodiment of the utility model, the workbench 1 includes a calibration slide 11 and a calibration slider 12, the calibration slide 11 is arranged on the base 2 at an inclination of 45 degrees, two calibration sliders 12 are provided, the two calibration sliders 12 are symmetrically arranged on both sides of the calibration slide 11 and are adapted to the inclination angle of the calibration slide 11, a slide groove 14 is formed between the two calibration sliders 12, and two PI N angle grooves 13 are provided on the two calibration slides 11, and the shape formed by the slide groove 14 and the two PI N angle grooves 13 is just adapted to the product to be calibrated;

[0028] When the angle of the required PIN leg of the liquid crystal display module is to be checked, the PIN leg of the liquid crystal display module is placed at the starting points of the two PIN angle grooves 13, and then the check can be realized.

[0029] In a further preferred embodiment of the utility model, the upper ends of the two PIN angle grooves 13 are both conical hollow settings, and the upper and lower end sizes of the two PIN angle grooves 13 are set according to the upper and lower limits of the size converted from the upper and lower limits of the angle allowable tolerance;

[0030] Because the two PI N angle grooves are set according to the upper and lower limits of the PI N angle, the upper and lower end dimensions are compatible with the dimensions of the required calibration product;

[0031] When the operator calibrates the angle of the PIN leg of the required liquid crystal display module, since the two PIN angle grooves 13 themselves are adapted to the size of the required calibration product, it is inconvenient for the operator to place the required calibration product from the starting points of the two PIN angle grooves 13, which will affect the efficiency of the operator's calibration. By setting the upper ends of the two PIN angle grooves 13 to be conical and hollow, the operator can more conveniently place the PIN leg of the required liquid crystal display module from the starting points of the two PIN angle grooves 13 for calibration when calibrating the angle of the PIN leg of the required liquid crystal display module.

[0032] In a further preferred embodiment of the utility model, a buffer elastic pad 3 is provided at the upper end of the base 2 and below the workbench 1, and the buffer elastic pad 3 is connected to the upper end of the base 2 by adhesive bonding;

[0033] During the process of the operator verifying the angle of the PIN leg of the required LCD module, since the PIN leg of the LCD module slides out through the two PIN angle grooves 13 and finally slides onto the base 2, in the above process, the PIN leg of the LCD module to be verified is prone to hit its corner due to the buffering force of the sliding, thereby causing product damage. Furthermore, if the PIN leg of the required LCD module passes the verification, when it is damaged during the sliding process, it cannot be discovered in the first time, affecting the subsequent product sales and product quality and reputation. A buffer elastic pad 3 is provided at the upper end of the base 2 and below the workbench 1, so that after the PIN leg of the required LCD module slides after the verification is completed, it will fall onto the buffer elastic pad 3, thereby avoiding the damage of the PIN leg of the LCD module during the verification process.

[0034] In a further preferred embodiment of the present invention, the base 2 includes a base plate 21 and a support plate 22, the base plate 21 is arranged on a horizontal plane, the support plate 22 is arranged on the base plate 21, and the support plate 22 is inclined at 45 degrees.

[0035] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
