Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, specifically to a circuit board programming and testing structure. Background Technology

[0002] Circuit boards are an important structure in modern electronic devices, and almost all electronic devices rely on them. Their applications cover many fields. The programming of circuit boards is a key part of the circuit board manufacturing process. Ensuring the quality of the programmed data is of paramount importance. In order to ensure the integrity and consistency of the programmed data, it is necessary to test the circuit board programming process.

[0003] Existing technologies have made many improvements to this. For example, Chinese patent CN216957460U discloses a programming clamping fixture and a testing device. The programming clamping fixture includes a base, a programming head, a support base, and a pressure cover. The programming head is movably disposed on the base in the vertical direction. The support base is movably disposed on the base in the horizontal plane. A circuit board is provided on the support base, and a mounting position is formed on the circuit board for mounting the chip to be programmed. The pressure cover is placed on the circuit board to fix the circuit board on the support base. Two limiting parts spaced apart on the pressure cover are formed to restrict the movement of the chip to be programmed in the horizontal direction. This device can improve the reliability of circuit board clamping and fixing to a certain extent.

[0004] However, it still has the following shortcomings in actual use:

[0005] 1. Its pressure cap only restricts the left and right movement of the chip through two limiting parts, and does not have an effective top-down clamping mechanism for the circuit board itself, so the fixation reliability of the circuit board is limited.

[0006] 2. The circuit board, pressure cover and support base are fixed by bolts. When disassembling, the bolts need to be loosened. Replacing the chip or maintaining the circuit board is very cumbersome, time-consuming and labor-intensive.

[0007] Based on this, the present invention designs a circuit board programming and detection structure to solve the above problems. Utility Model Content

[0042] The quick-release assembly includes positioning balls 228, positioning posts 229, and a locking assembly. There are two sets of positioning balls 228. One set of positioning balls 228 is located at the front right end of the substrate 210, and the other set of positioning balls 228 is located at the rear left end of the substrate 210. The two sets of positioning balls 228 are fixedly connected to the substrate 210. Two sets of positioning posts 229 are fixedly connected to the upper end of the base frame 1.

The locking structure is connected to the substrate 210 and the base frame 1.

[0043] The locking structure includes a knob 230, a rotating rod 231, a limiting rod 232, a fixing rod 233, and a quick-release upper fixing block 236. The quick-release upper fixing block 236 is fixedly connected to the base plate 210. The rotating rod 231, located at the center of the quick-release upper fixing block 236, is rotatably connected to the quick-release upper fixing block 236. Two sets of limiting rods 232, symmetrically distributed about the rotating rod 231, are fixedly connected above the rotating rod 231. Two sets of limiting rods 232 are provided on the quick-release upper fixing block 236 for accommodating... The right-angle limiting groove 235 of the limiting rod 232 is a quarter circle, that is, the limiting rod 232 can only rotate 90 degrees in the right-angle limiting groove 235. Two sets of fixed rods 233 are fixedly connected below the rotating rod 231, which are symmetrically distributed about the rotating rod 231. A quick-release lower fixing block 239 is fixedly connected to the upper end of the base frame 1. The quick-release lower fixing block 239 has a fixing groove 234 for accommodating the fixing rod 233. The fixing groove 234 is a rectangular groove.

[0044] The visual recognition component includes a laser emitter 237 and a light sensor 238. The laser emitter 237 and the light sensor 238 are symmetrically distributed front and back. The laser emitter 237 and the light sensor 238 are located at the front and back ends of the substrate 210, respectively. The lower ends of the laser emitter 237 and the light sensor 238 are fixedly connected to the substrate 210. Both the laser emitter 237 and the light sensor 238 have three sets.

[0045] When the fixed stage 212 moves to the leftmost end, the laser emitter 237 and the light sensor 238 are located in the middle of the fixed stage 212. If the programming circuit board 3 is not placed on the fixed stage 212, the light emitted by the laser emitter 237 can be detected by the light sensor 238.

[0046] like Figure 4 As shown, when the fixed stage 212 moves to the rightmost end, the laser emitter 237 and the light sensor 238 at the left end are located to the left of the positioning claw 214 at the left end. At this time, the light emitted by the laser emitter 237 at the left end can be detected by the light sensor 238, while the light emitted by the laser emitters 237 at the middle and right ends cannot be detected by the light sensor 238.

[0047] In this invention, a robotic arm transfers the programming circuit board 3 onto a fixed stage 212. Four sets of positioning claws 214 position the four corners of the programming circuit board 3, and four sets of support columns 215 support the programming circuit board 3 from below. At this time, the light emitted by the three laser emitters 237 is blocked, and the light sensor 238 cannot detect the light emitted by the laser emitters 237. The slide cylinder 211 on the substrate 210 is activated, and the slide cylinder 211 pushes the fixed stage 212 to the right until the detector 217 enters the programming circuit board 3 and closes the substrate 210. The detector 217 on the detection stage 216 then begins to detect the programming circuit board 3. The circuit board 3 is tested. The hydraulic buffer 213 plays a limiting and buffering role during movement, which will not damage the probes of the circuit board 3 and the detector 217. At this time, the laser emitter 237 and the light sensor 238 at the left end are located to the left of the positioning claw 214 at the left end. At this time, the light emitted by the laser emitter 237 at the left end can be detected by the light sensor 238, while the light emitted by the laser emitter 237 at the middle and right ends cannot be detected by the light sensor 238. If the results of the laser emitter 237 and the light sensor 238 are deviated when they are in the corresponding positions, the technicians can check accordingly.

[0048] When the fixed stage 212 moves from left to right, the rightward movement of the fixed stage 212 causes the limiting plate 218 to move to the right, thereby causing the limiting groove 219 to move the oblique moving column 222. Under the limiting action of the limiting hole 221 on the limiting frame 220, the oblique moving column 222 can only move downward with the vertical moving column 223. The downward movement of the vertical moving column 223 causes the pressure block 224 to move downward. The downward movement of the pressure block 224 causes the pressure plate 225 and the pressure column 226 to move downward. When the fixed stage 212 moves to the rightmost end, the pressure plate 225 just presses down and fixes the programming circuit board 3.

[0049] After the detector 217 completes the detection, the slide cylinder 211 resets, which drives the fixed stage 212 to reset. The reset of the fixed stage 212 drives the limit plate 218 to reset. The reset of the limit plate 218 drives the oblique moving column 222 and the vertical moving column 223 to move upward and reset, thereby causing the pressure block 224, the pressure plate 225 and the pressure column 226 to reset. At this time, the pressure plate 225 no longer presses down to fix the programming circuit board 3. When the fixed stage 212 moves to the leftmost end, the robotic arm removes the detected programming circuit board 3. The base frame 1 has multiple sets of circuit board programming and detection mechanisms 2. The robotic arm can move different programming circuit boards 3 to different circuit board programming and detection mechanisms 2 for sequential detection, which improves the detection efficiency.

[0050] Spring 227 plays a protective role. When the circuit board 3 has a slight height deviation, the pressure plate 225 will compress the spring 227 when pressing down on the circuit board 3, thereby causing the pressure column 226 to move upward, keeping the pressure plate 225 pressing the circuit board 3 while also playing a buffering role.

[0051] When it is necessary to replace or repair the base frame 1, rotate the knob 230 to align the fixing rod 233 with the fixing groove 234. At this time, the substrate 210 can be taken out. When replacing, align the positioning post 229 on the base frame 1 with the positioning groove on the positioning ball 228. At this time, the fixing rod 233 is aligned with the fixing groove 234 on the quick-release lower fixing block 239. After placing the substrate 210, rotate the knob 230 to make the fixing rod 233 perpendicular to the fixing groove 234, and the substrate 210 is locked to the base frame 1.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
