Description

Technical Field

[0001] The present invention relates to the technical field of instrument function detection, and particularly relates to an intelligent cockpit instrument function detection fixture, a detection device and a detection method. Background Art

[0002] Currently, the 7-inch combined instrument and the full-screen combined instrument in the intelligent cockpit consist of a 7-inch liquid crystal module in the middle and bracket dials on both sides. In the function detection process, after the combined instrument assembly is placed in the detection fixture, the docking connector at the bottom of the detection fixture will lift the combined instrument assembly. During the manufacturing and assembly of parts, due to dimensional tolerances, air pressure, and stress of the assembled parts, etc., the assembly will be unstable during testing. Therefore, after placing the combined instrument assembly, covering the surface assembly device of the detection fixture, i.e., the upper cover structure, is a necessary process consideration. The common function detection of automotive intelligent cockpit displays is divided into two types. One is to test after the circuit board device assembly is burned, and the other is to detect after assembling into an assembly. Assembling into an assembly has relatively high requirements for parts, and detecting after assembling into an assembly is more common.

[0003] In the related art, when detecting after assembling into an assembly, a box-type structure is usually used to accommodate the assembly for detection. The plug-in of the box-type structure is docked with the docking connector of the combined instrument assembly, and the upper fixture presses the assembly tightly through point contacts at more than four points.

[0004] However, in the traditional technical solution for detecting after assembling into an assembly, point contact easily causes the assembly to be unbalanced, resulting in unstable contact and detection. At the same time, in the traditional technical solution, placed in a closed box-type structure, whether the assembly is accurately placed in position and whether the upper fixture is accurately clamped in place are judged manually, and these subtle differences will all lead to unstable subsequent detection.

[0025] The beneficial effects brought by the technical solution provided by the embodiment of the present application at least include:

[0026] 1. In the detection fixture of the present application, a vertically liftable product docking connector is arranged inside the lower box body.

The support plate 23 is arranged on the upper surface of the lower box body, and the lower product fixture is arranged on the upper surface of the support plate 23. A product detection sensor 26 for detecting whether the instrument to be inspected is placed in place is arranged on the top surface of the lower product fixture. When the instrument to be inspected is not placed in place, the product detection sensor 26 will detect that the placement is unqualified. Only when the detection shows that it is placed in place can the subsequent lid closing operation be carried out. Two convex structures are symmetrically arranged on both sides of the support plate 23, and a locking bolt 21 is arranged at the front of the convex structure.

[0041] The upper cover assembly 1 includes an upper cover body and locking hooks 11 arranged on the left and right sides of the upper cover body.

[0049] For the detection fixture of the present application, the damping spring 14 slowly bounces up the upper cover body after the locking pin 21 unlocks the upper cover body, which can improve the efficiency of replacing the instrument to be detected during batch detection, and thus improve the detection efficiency.

[0050] Furthermore, the convex structure is provided with a row of angle adjustment holes 24 arranged at equal intervals, and the bottom end of the damping spring 14 is matched and connected to any one of the angle adjustment holes 24.

[0051] For the detection fixture of the present application, by changing the angle adjustment hole 24 matched with the bottom end of the damping spring 14, the opening angle of the upper cover body can be changed to meet the needs of operators of different heights.

[0052] In one embodiment, the upper cover body is rotatably connected to the convex structures on both sides through a rotating shaft 16 to achieve opening and closing.

[0053] The areas of the upper cover body corresponding to the upper product fixture 13 and the lower product fixture are made of transparent materials for easy observation. Preferably, the transparent material is a transparent acrylic board.

[0054] For the detection fixture of the present application, the areas of the upper cover body corresponding to the upper product fixture 13 and the lower product fixture are made of transparent materials, which is convenient for observing the indicator lights, liquid crystal displays and pointer movement states of the instrument to be detected during detection, and improves the detectability.

[0055] Preferably, an upper cover handle 15 is vertically arranged outward on the upper cover body, a lower box body handle 32 is also arranged on the front end face of the lower box body, and side handles 33 are also arranged on the left and right end faces of the lower box body.

After the instrument to be tested is placed in place and the upper cover body is closed in place, the product docking connector 35 is vertically lifted again to align with the probe 36 of the instrument to be tested, which can effectively avoid interference during the placement stage or the cover closing stage, thereby improving the contact stability in disguise, and then improving the subsequent detection stability.

[0058] In one embodiment, the lower box 3 further includes a counter 31. Each time a meter to be inspected is inspected, the counter 31 counts once.

[0059] The detection fixture of the present application, the lower box body 3 also includes a counter 31, the counter 31 can record the number of instruments to be tested, and can efficiently count when testing the instruments to be tested in batches. At the same time, the counter 31 can ensure the authenticity of the data, monitor the number of times the fixture probe is used, and provide a technical reference for the maintenance and repair of the detection fixture.

[0060] In the second aspect, the present application also discloses an embodiment of an instrument function detection device, the detection device includes a detection cabinet and the above-mentioned detection fixture, and the lower box 3 of the detection fixture also includes a device docking connector 34.

The upper cover assembly 1 also includes a damping spring 14, the top end of the damping spring 14 is fixed to the side end surface of the upper cover body, and the bottom end of the damping spring 14 is connected to the side end surface of the protruding structure; the damping spring 14 is used to slowly pop up the upper cover body after the locking pin 21 unlocks the upper cover body.

[0065] For the detection device of the present application, when the upper cover body is closed, the positioning post 12 is inserted into the mating groove of the convex structure, which can further ensure the closing accuracy of the upper cover body, and thus improve the detection stability laterally. The damping spring 14 slowly bounces up the upper cover body after the locking pin 21 unlocks the upper cover body, which can improve the efficiency of replacing the instrument to be detected during batch detection, and thus improve the detection efficiency.

[0066] In a third aspect, the present application also discloses a detection method based on the above detection fixture, including the following steps:

[0067] Open the upper cover body, place the instrument to be detected on the upper surface of the lower product fixture. After the product detection sensor 26 senses that the instrument to be detected is placed in place, close the cover.
