Description

Technical Field

[0001] The utility model relates to a curved surface fitting jig, in particular to a curved surface fitting jig used in the field of detectors. Background Art

[0002] The curved surface fitting jig is an online inspection and testing jig. It is a standard test equipment that tests the principle, performance and electrical connection of online curved surface components to check for manufacturing defects and component failures. However, when observing the side view of light with the naked eye, the constantly changing light will affect the health of the side viewer's eyes, making it inconvenient to perform inspection operations.

[0003] The specification of Chinese patent CN212872828U discloses a semi-automatic lighting test fixture, including a lighting box, a pressing handle and a clamping plate slidably connected by a slide groove. The utility model covers the lighting test bottom plate with a layer of brown shading plate, which can not only see the light emitted by multiple lamp posts, but also block the glare of LED lights, thus solving the problem of fatigue of naked eye judgment.

[0004] The specification of Chinese patent CN203101766U discloses a liquid crystal panel lighting device, comprising: a shading plate, a probe base and a probe inserted on the probe base, and a reflector is provided on the shading plate. The utility model provides a liquid crystal panel lighting device, which enables the probe to be accurately aligned with the liquid crystal panel test point and improves the efficiency of liquid crystal panel lighting.

[0005] However, during the operation of the existing light bar to be inspected, the main body length is too long, and part of its area will roll under the equipment, resulting in an unclear inspection angle of the light bar to be inspected. In addition, the light bar to be inspected remains in a bent state, which will affect its integrity and is not conducive to ensuring the inspection efficiency of the light bar to be inspected. Therefore, it is necessary to design a curved surface fitting fixture that is easy to adjust the inspection base surface to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned existing technologies, the technical problem to be solved by the utility model is that the length of the existing light strip to be inspected is too long during operation, and part of its area will roll down under the equipment, resulting in an unclear detection angle of the light strip to be inspected, and the light strip to be inspected remains in a bent state, which will affect its integrity.

[0007] To solve the above problems, the utility model provides a curved surface fitting jig, including a back plate, a first bottom plate fixedly connected to the front side of the lower end of the back plate, a corrugated stretch tube fixedly connected to the front end of the first bottom plate, a second bottom plate fixedly connected to vertical poles on the left and right sides of the lower ends of the second bottom plate and the first bottom plate, a suction cup outer ring fixedly connected to the lower end of the vertical pole, a roller fixedly connected to the lower end of the vertical pole, springs fixedly connected to the left and right sides of the two vertical poles located at the lower end of the second bottom plate, a side pressure vertical plate fixedly connected to the lower end of the spring, and a pointed insertion rod fixedly connected to one end of the side pressure vertical plate close to the outer ring of the suction cup.

[0008] In the above-mentioned high-precision jig workpiece detector, this solution can match the length of the light bar to be tested with the length of the corrugated stretch tube according to the actual length of the light bar to be tested, so as to avoid the light bar to be tested from being too long and falling under the equipment during operation, resulting in unclear detection angle of the light bar to be tested, and the risk of the light bar to be tested remaining in a bent state during the detection process, affecting its integrity.

[0009] As a further improvement of the present application, the front end of the back plate is fixedly connected to a downward pressing connecting rod, and the lower end of the downward pressing connecting rod is fixedly connected to a downward pressing cross plate.

[0010] As a further improvement of the present application, a plurality of probes are installed at the lower end of the downward pressing horizontal plate, and the roller is located on the inner side of the outer ring of the suction cup.

[0011] As a further improvement of the present application, the pointed insertion rod cooperates with the outer ring of the suction cup, and a semi-arc circle is fixedly connected to the middle part of the front end of the second bottom plate.

[0012] As another improvement of the present application, a light bar to be detected is placed on the upper end of the corrugated stretch tube, and the light bar to be detected is located directly below the downward pressing horizontal plate.

[0013] As another improved supplement of the present application, first rotating shaft columns are fixedly connected to the middle parts of the ends of the first bottom plate and the second bottom plate close to each other, and the outer ends of the two first rotating shaft columns are symmetrically rotatably connected to the display rack rods.

[0014] As another improved supplement of the present application, two corresponding display rack rods are rotatably connected, and the display rack rods are located directly below the corrugated tensile tube.

[0015] In summary, this solution can adjust the length of the corrugated stretching tube of the second bottom plate mechanism according to the actual length of the light bar to be detected, so that the length of the corrugated stretching tube matches the light bar to be detected, thereby avoiding the light bar to be detected being too long and falling under the equipment during operation, resulting in unclear detection angle of the light bar to be detected, and the light bar to be detected being bent during the detection process, thereby affecting the risk of its integrity. At the same time, before stretching the second bottom plate, the two side pressure vertical plates on the front side can be pinched by hand to compress the spring, so that the pointed insertion rod is directly inserted into the outer ring of the suction cup, so that the outer ring of the suction cup is quickly separated from the desktop, and the second bottom plate follows the roller to quickly stretch and move on the desktop, thereby avoiding the need to move the entire equipment during the stretching process of the second bottom plate, thereby affecting the risk of equipment use efficiency.

[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0028] Figure 3 , 6 -7 shows that the front end of the back plate 1 is fixedly connected with a downward pressing connecting rod 2, the lower end of the downward pressing connecting rod 2 is fixedly connected with a downward pressing horizontal plate 3, a plurality of probes 4 are installed at the lower end of the downward pressing horizontal plate 3, the roller 16 is located on the inner side of the suction cup outer ring 11, the pointed insertion rod 15 cooperates with the suction cup outer ring 11, the middle part of the front end of the second bottom plate 9 is fixedly connected with a semi-arc circle 12, the upper end of the corrugated stretching tube 8 is placed with a light bar 17 to be detected, and the light bar 17 to be detected is located directly below the downward pressing horizontal plate 3.

[0029] Figure 1-3 It is shown that the present solution places the light bar 17 to be detected above the second bottom plate 9 and the first bottom plate 5, and the downward pressing connecting rod 2 drives the downward pressing cross plate 3 to bring the probe 4 into contact with the light bar 17 to be detected for light source detection. During the operation of the light bar 17 to be detected, the length of the corrugated stretching tube 8 of the second bottom plate 9 mechanism can be stretched and adjusted according to the actual length of the light bar 17 to match the length of the corrugated stretching tube 8 with the light bar 17 to be detected, so as to avoid the light bar 17 to be detected being too long and falling under the equipment during operation, resulting in unclear detection viewing angle of the light bar 17 to be detected, and the light bar 17 to be detected being kept in a bent state during the detection process, thereby affecting its integrity.
