Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass detection, in particular to a glass detection fixture. Background Art
[0002] In the production process of float glass, from raw material processing to batch melting in a high-temperature melting furnace, to forming in a tin bath, and finally annealing to the cold end to obtain glass products, the loss of control in each link may cause defects in the glass products. The main defects include: Bubbles: bubbles of different sizes will be generated inside, most of which are in the range of 0.1-1.0 in volume. These small bubbles cannot be seen from the outside normally; Stones: All kinds of solid inclusions in the glass are collectively referred to as stones regardless of their source, including unmelted batches and batch stones formed by insoluble substances that enter the melt with the batches; refractory stones formed by unmelted residues of refractory materials; crystallized stones precipitated from the glass itself; dripping stones slightly exposed on the glass surface caused by dripping liquid from the top of the cooling part or the top of the tin bath, etc.; Scratches: During the glass slicing process and boxing process, if it encounters objects with higher hardness or rubs against broken glass slag, it will cause scratches on the glass surface.
[0003] At present, it is generally inspected by naked eyes, but the inspection jigs in the prior art, such as 202223560549.5-A light guide plate inspection device, need to stick the glass to the reflective paper during inspection, and foreign objects underneath will cause defects. In addition, black glass, bakelite, etc. are used at the bottom, which requires very high flatness of the bottom of the jig. Utility Model Content
[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a glass detection fixture to achieve the purposes of simple structure, convenient detection operation and high detection efficiency.
[0005] The utility model protects a glass detection jig, comprising a frame, a support plate, a light bar and a plurality of pads; the light bar is attached to the side of the frame; the support plate is horizontally laid on the frame; the pads are arranged above the side of the frame, so that when the glass is placed on the frame for detection, the angle between the glass and the support plate is α, 0<α≤45°.
[0006] Preferably, 0<α≤30°.
[0007] Different from the prior art which places the glass to be tested directly on reflective paper and uses light for testing, the core design point of the utility model lies in the design of the pad, which makes the glass present a certain angle during testing. For the testers, visual inspection at a certain angle is more in line with ergonomics, and the inspection is more convenient, which improves the work efficiency of the testers. The glass to be tested does not need to contact the bottom, which avoids impurities on the bottom affecting the detection effect, and even increases the product defect rate due to contact with impurities. On the other hand, the glass to be tested is presented at a certain angle, which is more convenient to pick up and place, avoiding pressing on fingers during the picking and placing process, and is also convenient to find the force fulcrum, making it more convenient to lift.
[0008] Furthermore, the pad is L-shaped, with the bottom being welded or fixed to the frame body with screws, and the top serving as a supporting point in contact with the glass.
[0009] The pad is configured in an L-shape, the contact area between the bottom and the frame is increased, and welding or screw fixing is more stable.
[0010] Furthermore, the support plate is paved with reflective paper, which is laid on the support plate, and the light bar is illuminated, and the reflective paper is used to reflect the light onto the glass, which facilitates the inspection of the glass and avoids eye discomfort caused by direct light.
[0011] Preferably, there are three pads, and the distance between the pads is determined according to the width of the glass to be tested, and the pads are preferably arranged at both ends and the middle of the glass to be tested and are evenly distributed.
[0012] Furthermore, angle steels are welded to the inner sides of both ends of the frame, the upper ends of the angle steels are horizontal, the side edges of the angle steels are welded to the inner sides of the frame, and both ends of the support plate are horizontally mounted on the angle steels.
[0013] The angle steel is mainly used to install the support plate, which plays a major role in connection and load-bearing. At this time, one end of the glass to be tested is placed on the mounting plate, and the mounting plate is placed on the angle steel.
[0014] Furthermore, the frame body includes a support leg, a first bracket, a second bracket, a third bracket and a fourth bracket, the first bracket and the third bracket are fixed at the top end of the support leg; the first bracket is parallel to the third bracket; the second bracket and the fourth bracket are parallel to each other and fixed on the inner side of the support leg; a group of the angle steels are respectively welded to the inner walls of the first bracket and the third bracket.
[0015] Furthermore, one end of the second bracket and the fourth bracket is respectively arranged below the first bracket and perpendicular to the first bracket, and the other end is respectively arranged below the third bracket and perpendicular to the third bracket; the cushion block is fixed on the third bracket.
[0016] The glass inspection fixture of the utility model has a simple structure, and adopts legs and multiple groups of brackets to fix a square table structure. The legs play a role of load-bearing support. The first bracket, the second bracket, the third bracket and the fourth bracket are connected up and down with the tails closed, which can save space and has higher overall stability.
[0017] Furthermore, the frame body also includes a plurality of angle connection blocks connected to the frame body. The angle connection blocks are mainly used for fixing a plurality of brackets, and the two sides of the angle connection blocks are respectively attached to two connected brackets. For example, if the first bracket and the second bracket are connected vertically up and down, one side of the angle connection block is attached to the first bracket, and the bottom is attached to the second bracket; and so on, the overall structure is more stable.
[0018] Furthermore, the light bar is installed on the inner side of the first bracket and is located above the support plate.
[0019] Compared with the prior art, the beneficial effects of the utility model are:
[0020] The glass inspection fixture of the utility model can greatly improve the speed of inspecting glass defects and minimize the error rate. The inspection fixture of the utility model has a simple overall structure and occupies a small area, which greatly improves work efficiency and improves product quality.
[0021] The glass inspection fixture of the utility model allows the glass to present a certain angle during inspection. For inspectors, visual inspection at a certain angle is more in line with ergonomics, and there is no need to bend over 90 degrees to check, making inspection more convenient and improving the work efficiency of inspectors. The glass to be tested does not need to contact the bottom, avoiding impurities on the bottom that affect the inspection effect, and even increasing the product defect rate due to contact with impurities. On the other hand, the glass to be tested presents a certain angle, which is more convenient to pick up and put, avoiding pressing fingers during the picking and putting process, and is also convenient to find the force fulcrum, making it more convenient to lift.
