Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of LCD product processing, in particular to a device for correcting pins of LCD products. Background Art
[0002] With the rapid development of electronic technology, liquid crystal displays (LCDs) have gained widespread application in modern electronic devices due to their advantages such as lightness, low power consumption, and portability. The core component of an LCD product is the liquid crystal display (LCD), which is typically surrounded by multiple pins that connect to external circuits for signal transmission and control. The pin design of LCD products is crucial to ensuring proper operation, as it directly affects the quality and stability of the connection between the LCD and the circuit board.
[0003] During the LCD production process, pins undergo a series of precise processes, including snap-in, glue dispensing, UV curing, shearing, and testing. However, due to various factors, such as equipment accuracy, operator skill level, and production environment, the pin spacing of LCD products may be too large or too small. This phenomenon can cause the pins to not match the corresponding sockets on the circuit board, thus affecting the assembly of the LCD product.
[0004] To address this issue, LCD products typically require pin calibration after completing pin-related processes. Traditional calibration methods often rely on manual labor, which is not only inefficient but also difficult to ensure calibration consistency and accuracy. Furthermore, manual calibration can lead to product damage due to improper operation, increasing production costs and quality risks. Therefore, developing an automated, efficient LCD product pin calibration device is crucial for improving production efficiency, reducing costs, and ensuring product quality. Utility Model Content
[0005] In response to the deficiencies in the prior art, the purpose of the present utility model is to provide a pin correction device for an LCD product, comprising a bracket, a placement mechanism fixedly connected to the top end of the bracket, the placement mechanism being used to place the LCD product, and two groups of correction mechanisms fixedly connected to the bracket, the two groups of correction mechanisms being distributed on the front and rear sides below the placement mechanism, each group of correction mechanisms comprising a cylinder mounting plate, a first cylinder, a first clamping plate, a second cylinder and a second clamping plate, the cylinder mounting plate being fixedly connected to the bracket, the first cylinder being fixedly connected to the upper end of the cylinder mounting plate, the telescopic end of the first cylinder being fixedly connected to the first clamping plate, the second cylinder being fixedly connected to the lower end of the cylinder mounting plate, the telescopic end of the second cylinder being fixedly connected to the second clamping plate, and the relative movement of the first clamping plate and the second clamping plate being used to correct the pins of the LCD product.
[0006] Furthermore, the placement mechanism includes a fixing plate and a placing plate. The two fixing plates are fixedly connected to the top of the bracket symmetrically on the left and right sides, and the left and right ends of the placing plate are respectively connected to the left and right fixing plates.
[0007] Furthermore, it also includes an adjustment mechanism, which includes an adjustment plate and an adjustment block. The two adjustment plates are respectively installed on the top of the left and right fixed plates. The two adjustment plates are close to each other at one end and are fixedly connected with two front-to-back symmetrical adjustment blocks. There are strip holes on the top of the adjustment plate and the adjustment block, and the left-right spacing of the two adjustment plates and the front-to-back spacing of the two adjustment blocks are adjusted through the strip holes.
[0008] Furthermore, the adjustment mechanism also includes a spring and an adjustment rod. The two adjustment rods are symmetrically threaded to the front end of the bracket, and the rear ends of the two adjustment rods are against the front end of the cylinder mounting plate on the front side. The two springs are symmetrically distributed on the left and right, and their front and rear ends are respectively clamped with the bracket and the front cylinder mounting plate.
[0009] Furthermore, it also includes a supporting mechanism, which includes a guide rail mounting plate and a guide rail. The two guide rail mounting plates are fixedly connected to the bracket symmetrically on the left and right. The middle of the guide rail mounting plate is located below the fixed plate, and the two guide rail mounting plates are fixedly connected to the guide rail on one side close to each other.
[0010] Furthermore, sliders are fixedly connected to the left and right sides of the second clamping plate, and the bottom ends of the sliders are in contact with the top ends of the guide rails.
[0011] Furthermore, the top end of the guide rail mounting plate contacts the bottom end of the fixing plate.
[0012] Furthermore, a U-shaped groove is opened on the top of the fixing plate, the U-shaped grooves on the two fixing plates are opened opposite to each other, and the adjusting plate is fixedly connected to the U-shaped groove.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. By setting up two sets of front and rear correction mechanisms, the first cylinder drives the first clamping plate to move, and the second cylinder drives the second clamping plate to move. The first clamping plate and the second clamping plate of each set of correction mechanisms move in opposite directions, bending the LCD product pins into a state perpendicular to the LCD product main part (liquid crystal display), thereby achieving high-efficiency and automatic correction of the LCD product pins.
[0015] 2. By setting up an adjustment mechanism, rotating the adjustment rod drives the front cylinder mounting plate to move back and forth, thereby driving the front correction mechanism to move back and forth, and then the distance between the front and rear correction mechanisms can be changed; by changing the left and right installation distance of the two adjustment plates, it can adapt to LCD products of different lengths, and by changing the installation distance of the front and rear adjustment blocks, it can adapt to LCD products of different widths.
[0016] 3. By setting up a supporting mechanism and arranging a slider on the second clamping plate, and allowing the slider to slide on the guide rail on the supporting mechanism, the overturning moment of the second clamping plate on the second cylinder can be reduced, thereby extending the service life of the second cylinder; the contact between the top of the supporting mechanism and the fixed plate can also increase the stability of the fixed plate.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the specific implementation methods of the present invention are clearly and completely described below to further illustrate the present invention. Obviously, the specific implementation methods described are only part of the implementation methods of the present invention, rather than all styles.
[0025] like Figures 1 to 4As shown, the LCD product pin correction device includes a bracket 1, the top of the bracket 1 is fixedly connected to a placement mechanism 2, the placement mechanism 2 includes a fixing plate 21 and a placement plate 22, the two fixing plates 21 are fixedly connected to the top of the bracket 1 symmetrically, and the left and right ends of the placement plate 22 are respectively connected to the left and right fixing plates 21. The placement mechanism 2 is used to place the LCD product 6. The structure of the LCD product 6 is as shown in FIG. Figure 5 As shown, it has pins on both the front and back sides. When placed, the pins face downward, and the middle main body (LCD screen) is placed on the placement plate 22. Two sets of correction mechanisms 3 are also fixedly connected to the bracket 1. The two sets of correction mechanisms 3 are distributed on the front and back sides below the placement mechanism 2. Each set of correction mechanisms 3 includes a cylinder mounting plate 31, a first cylinder 32, a first clamping plate 33, a second cylinder 34, and a second clamping plate 35. The cylinder mounting plate 31 is fixedly connected to the bracket 1. The first cylinder 32 is fixedly connected to the upper end of the cylinder mounting plate 31. The telescopic end of the first cylinder 32 is fixedly connected to the first clamping plate 33. The second cylinder 34 is fixedly connected to the lower end of the cylinder mounting plate 31. The telescopic end of the second cylinder 34 is fixedly connected to the second clamping plate 35. The relative movement of the first clamping plate 33 and the second clamping plate 35 is used to calibrate the pins of the LCD product 6.
[0026] When using this device, first place the LCD product 6 with its pins facing downward on the placement plate 22. Taking the previous set of correction mechanisms 3 as an example, start the first cylinder 32 and the second cylinder 34. The first cylinder 32 drives the first clamping plate 33 to move backward, and the second cylinder 34 drives the second clamping plate 35 to move forward. Regardless of whether the front pins of the LCD product 6 are tilted forward or backward, they can be clamped by the first clamping plate 33 and the second clamping plate 35 to be bent into a state perpendicular to the main part of the LCD product 6 (liquid crystal display screen). The principle of the subsequent set of correction mechanisms 3 is the same and will not be repeated here. In this way, the correction of the pins of the LCD product 6 is completed.
[0027] The bracket 1 further includes an adjustment mechanism 4, which includes an adjustment plate 41, an adjustment block 42, a spring 43, and an adjustment rod 44. A U-shaped groove is formed at the top of the fixed plate 21, with the U-shaped grooves on the two fixed plates 21 facing each other. The adjustment plate 41 is fixedly connected to the U-shaped groove. Two adjustment blocks 42 are fixedly connected to the ends of the two adjustment plates 41, which are close to each other. The adjustment plates 41 and the adjustment blocks 42 have strip holes on the tops, through which the left-right spacing between the two adjustment plates 41 and the front-to-back spacing between the two adjustment blocks 42 can be adjusted. Two adjustment rods 44 are symmetrically connected to the front end of the bracket 1, with the rear ends of the two adjustment rods 44 resting against the front end of the front cylinder mounting plate 31. Two springs 43 are symmetrically distributed, with their front and rear ends respectively engaging the bracket 1 and the front cylinder mounting plate 31.
[0028] When it is necessary to calibrate the pins of LCD products 6 of different sizes, this can be achieved through the adjustment mechanism 4. When it is necessary to reduce the distance between the front and rear sets of correction mechanisms 3, simply rotate the adjustment rod 44 to move the front cylinder mounting plate 31 backward, thereby moving the front correction mechanism 3 backward to reduce the distance. At this time, the spring 43 is in a stretched state. When it is necessary to increase the distance between the front and rear sets of correction mechanisms 3, rotate the adjustment rod 44 in the opposite direction, and the front cylinder mounting plate 31 moves forward under the elastic force of the spring 43, causing the front correction mechanism 3 to move forward to increase the distance. Accordingly, when the distance between the front and rear sets of correction mechanisms 3 changes, the placement mechanism 2 also needs to be changed. Increasing the left-right installation distance of the two adjustment plates 41 can accommodate longer LCD products 6, while decreasing the left-right installation distance of the two adjustment plates 41 can accommodate shorter LCD products 6. Increasing the installation distance of the front and rear adjustment blocks 42 can accommodate wider LCD products 6, while decreasing the installation distance of the front and rear adjustment blocks 42 can accommodate narrower LCD products 6.
[0029] It also includes a supporting mechanism 5, which includes a guide rail mounting plate 51 and a guide rail 52. The two guide rail mounting plates 51 are fixedly connected to the bracket 1 in a symmetrical manner. The middle part of the guide rail mounting plate 51 is located below the fixed plate 21, and the two guide rail mounting plates 51 are fixedly connected to the guide rail 52 on the side close to each other. The second clamping plate 35 is fixedly connected to the side away from each other, and the bottom end of the slider 351 contacts the top end of the guide rail 52. Since the second clamping plate 35 is a curved structure and is heavier than the first clamping plate 33, by adding the slider 351 thereto, when the second cylinder 34 drives the second clamping plate 35 to move back and forth, the slider 351 slides on the guide rail 52, which can reduce the overturning moment generated by the second clamping plate 35 on the second cylinder 34, thereby extending the service life of the second cylinder 34. The top end of the guide rail mounting plate 51 contacts the bottom end of the fixed plate 21, which can increase the stability of the fixed plate 21.
