Description

Technical Field

[0001] The utility model belongs to the field of plate detection, and specifically relates to a luminous plate detection fixture. Background Art

[0002] In modern manufacturing, luminous panels are widely used in architectural decoration, lighting equipment, display manufacturing, solar energy products and other fields due to their unique optical properties. With the improvement of industry standards and consumers' increasingly stringent requirements for product quality, accurate detection of luminous panels has become an indispensable part of the production process. Traditional luminous panel detection methods often rely on manual visual inspection or simple tool assistance. This method is not only time-consuming and labor-intensive, but the detection results are greatly affected by subjective factors, making it difficult to ensure the consistency and accuracy of the detection.

[0003] For example, the utility model patent with publication number CN220207032U discloses a fixing fixture for detecting light leakage of a light-transmitting plate, including a fixing component, wherein the fixing component includes a mounting frame, two limit protrusions, two support plates, an adjusting knob, a screw, two guide columns, a light-transmitting plate, a pressure plate, two limit grooves, a pull plate, two slide grooves, two pressure grooves and a sinking groove; the sinking groove is opened on the upper part of the inner wall of the mounting frame to fix the light-transmitting plate for detection, but it is not suitable for use in the automatic detection and lighting machine introduced in the industry. The automatic lighting detection effect of the automatic detection and lighting machine is significantly better than manual detection, but due to the large number of small-pitch lamp beads, it is still impossible to achieve rapid positioning, the efficiency is low and it is easy to find the wrong position.

[0007] Preferably, sliding grooves are provided in parallel on two opposite inner side walls of the U-shaped frame, and the guide tooling strip is slidably inserted into the sliding grooves.

[0008] Preferably, the cross section of the guide tooling strip is L-shaped, and the plate to be tested is installed on the short side of the L-shaped guide tooling.

[0009] Preferably, a flexible support pad is provided on the contact surface between the guide tooling strip and the plate to be tested.

[0010] Preferably, the guide tooling strip is provided with a raised limiting structure at an edge corresponding to the upper surface of the plate to be tested.

[0011] Preferably, at least one vacuum suction cup is provided on the flexible support pad.

[0012] Preferably, self-lubricating guide plates are installed on the sides of the guide tooling strip that contact the U-shaped frame.

[0014] Preferably, a guiding slope is provided at the opening of the sliding groove.

[0015] Preferably, outer edges of the U-shaped frame are all provided with chamfers.

[0016] After adopting the above technical solution, the luminous plate detection fixture provided by the utility model has the following beneficial effects compared with the prior art.

[0017] (1) The method of installing the plate to be tested on the U-shaped frame by means of the guide tooling strip simplifies the operation process and improves the installation efficiency. The marking point design on the upper surface of the U-shaped frame facilitates the rapid and accurate positioning of the detection area and enhances the detection accuracy. The setting of the positioning column can quickly install the U-shaped frame on the detection equipment and effectively fix the position of the fixture on the detection equipment, ensuring the stability during the detection process and reducing the measurement error caused by vibration.

[0018] (2) By opening a sliding groove on the inner wall of the U-shaped frame and slidingly inserting the guide tooling strip, the plate to be tested can be quickly positioned and adjusted, which improves the flexibility and efficiency of plate loading. At the same time, the parallelism of the plate is ensured, and the consistency and accuracy of the test results are improved.

DETAILED DESCRIPTION

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a luminous plate inspection fixture, including a U-shaped frame 1 with a single-side opening, in which a plate 2 to be tested is installed, and the plate 2 to be tested is installed to the U-shaped frame 1 through a guide tooling strip 3, and marking points are provided on the upper surface of the U-shaped frame 1, and a positioning column 4 is installed on the lower surface of the U-shaped frame 1 away from the opening side.

[0026] The method of installing the plate 2 to be tested to the U-shaped frame 1 through the guide tooling strip 3 simplifies the operation process and improves the installation efficiency. The marking point design on the upper surface of the U-shaped frame 1 facilitates the rapid and accurate positioning of the detection area and enhances the detection accuracy. The setting of the positioning column 4 can quickly install the U-shaped frame 1 to the detection equipment and effectively fix the position of the fixture on the detection equipment, thereby ensuring the stability during the detection process and reducing the measurement error caused by vibration.

[0027] The U-shaped frame 1 has two parallel sliding grooves on the two opposite inner side walls, and the guide tooling strip 3 is slidably inserted into the sliding grooves. The plate 2 to be tested is installed on the guide tooling strip 3 and then inserted into the sliding groove to achieve installation. By opening the sliding groove on the inner side wall of the U-shaped frame 1 and slidingly inserting the guide tooling strip 3, the plate 2 to be tested is quickly positioned and adjusted, which improves the flexibility and efficiency of plate loading, while ensuring the parallelism of the plate, and improving the consistency and accuracy of the test results.

[0028] Furthermore, the transversely connected sides of the U-shaped frame 1 may be provided with a telescopic structure (not shown in the figure) to adjust the distance between the two side sides of the U-shaped frame 1 to achieve detection of panels of different sizes.

[0029] Preferably, the cross section of the guide tooling strip 3 is L-shaped, and the plate to be tested 2 is installed on the short side of the guide tooling L. The guide tooling strip 3 adopts an L-shaped cross-section design, and the short side contact design reduces the obstruction of the plate surface and does not block the upper surface of the plate, which is beneficial to light propagation and improves the accuracy of light detection.

[0030] A flexible support pad is provided on the contact surface between the guide tooling strip 3 and the plate to be tested 2. The flexible support pad is provided on the contact surface between the guide tooling strip 3 and the plate to be tested 2, which can adapt to plates of different thicknesses and shapes, reduce pressure damage to the plate surface, and provide uniform support force, ensuring that the plate surface is flat during testing, thereby improving the reliability of the test data.

[0031] Furthermore, the edge of the guide tooling strip 3 corresponding to the upper surface of the plate 2 to be tested is provided with a raised limiting structure (not shown in the figure). The limiting structure can be a small protrusion or the like provided on the side of the guide tooling strip 3 corresponding to the plate 2 to be tested to achieve the limiting effect. The raised limiting structure on the edge of the guide tooling strip 3 effectively prevents the plate 2 to be tested from slipping during the detection process, ensures accurate positioning of the plate, and enhances the stability and safety of the detection.

[0032] Alternatively, at least one vacuum suction cup is provided on the flexible support pad, and multiple vacuum suction cups may be provided along the guide tooling strip 3. The vacuum suction cups provided on the flexible support pad can firmly adsorb the plate 2 to be tested, and can keep the plate stable and not fall off even when the jig needs to be turned over or moved, thereby further improving the convenience and efficiency of detection.

[0033] Self-lubricating guide plates are installed on the sides of the guide tooling strip 3 that contact the U-shaped frame 1. The self-lubricating guide plates are installed on the contact surfaces of the guide tooling strip 3 and the U-shaped frame 1, which reduces friction resistance, makes the guide tooling strip 3 slide more smoothly, prolongs its service life, and also reduces operating noise and improves the working environment.

[0034] Preferably, the first positioning permanent magnet is installed at one end of the guide tooling strip 3 inserted into the U-shaped frame 1, and the second positioning permanent magnet or magnetic conductive plate is provided at the end of the sliding slot of the U-shaped frame 1 corresponding to the positioning permanent magnet. Through the magnetic attraction between the first positioning permanent magnet and the second positioning permanent magnet or magnetic conductive plate, the precise positioning and locking of the guide tooling strip 3 is achieved, and then the plate 2 to be tested is locked, which is not only simple and quick to operate, but also ensures the stability of the position during the detection process.

[0035] Preferably, a guiding bevel is provided at the opening of the sliding groove. The guiding bevel design at the opening of the sliding groove makes the insertion of the guide tooling strip 3 easier and smoother, reduces the resistance and wear during insertion, improves work efficiency, and protects the sliding groove and the guide tooling strip 3 from damage.

[0036] Preferably, the outer edges of the U-shaped frame 1 are all chamfered. The chamfered outer edges of the U-shaped frame 1 not only beautify the appearance of the fixture, but more importantly, eliminate the harm that the sharp edges may cause to the operator, improve the safety of use, and also avoid unnecessary scratches and damage to other equipment or materials during transportation and storage, and can also insert the detection equipment more smoothly.

[0037] During operation, the plate 2 to be tested is installed on the flexible support pad of the guide tooling strip 3, the plate 2 to be tested is clamped by the limiting structure, and then the guide tooling strip 3 is inserted into the sliding groove along the guide inclined surface. In this process, the chamfer of the outer edge of the U-shaped frame 1 can assist in achieving the insertion effect. At the same time, the self-lubricating guide plate (not shown in the figure) on the guide tooling strip 3 assists in lubrication, and the plate 2 to be tested installed with the guide tooling strip 3 can be smoothly inserted into the U-shaped frame 1, and then the first positioning permanent magnet on the guide tooling strip 3 cooperates with the second positioning permanent magnet or the magnetic conductive plate fixed on the U-shaped frame 1 to achieve magnetic positioning, and the installation process can be realized. Then, the installed overall structure is inserted into the detection equipment, and the detection can be started when the positioning column 4 is inserted into place.
