Description

Technical Field

[0001] This utility model belongs to the field of circuit board testing technology, and in particular relates to a control motherboard testing fixture. Background Technology

[0002] A control motherboard is a type of circuit board that is mainly used for mounting and controlling other electronic components. Before leaving the factory, control motherboards need to undergo performance testing. Only control motherboards that pass the test can be sold normally. In order to ensure the speed and smoothness of the testing process, the testing of control motherboards relies on ICT test fixtures. The ICT test fixtures use probes to contact the PCB test points to detect parameters such as circuit continuity, voltage, and current, and verify the correctness of component installation and electrical connection.

[0003] Chinese patent application CN220455470U discloses a motherboard testing fixture, including a housing. A first positioning component is fixedly installed on the outer upper part of the housing. A base is movably connected to the upper part of the housing via the first positioning component. A fixing frame is fixedly installed on the rear upper part of the housing. A support sleeve is installed on the front of the fixing frame, and a pressure rod is slidably connected inside the support sleeve. This utility model, using the above structure, allows for motherboard testing by pulling the lever upwards, which moves the pressure plate simultaneously via the connecting frame and the pressure rod. The motherboard is then placed on the base, and the lever is pressed downwards. The support sleeve stabilizes the position of the pressure rod, and the second positioning component stabilizes the position of the pressure plate, causing the pins to contact the motherboard. Circuit connectors are then inserted into the motherboard's terminals, allowing for testing. This makes motherboard positioning more convenient and faster, effectively improving testing efficiency.

[0004] The aforementioned motherboard testing fixture has springs on its upper sidewalls, connecting the fixture to a base. Positioning rods are slidably inserted into the four corners of the base, and grooves on the upper sidewalls of the base are used for placing and supporting the motherboard. However, when the motherboard is placed in these grooves, it becomes embedded, making it difficult to remove after testing. Furthermore, while the base supports the motherboard, the placement and removal of the motherboard requires manual operation, and only one motherboard can be tested at a time. After testing, the motherboard must be manually removed and replaced, consuming significant test preparation time. Therefore, we provide a controllable motherboard testing fixture to solve these problems. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1-3 This utility model is a control motherboard testing fixture, including a machine base 1 and a conveying assembly 3. The conveying assembly 3 includes a conveyor belt 301 set on the machine base 1. A drive rod 302b is set at the end of the conveyor belt 301. The end of the drive rod 302b is also connected to the output shaft of the motor 302. That is, the transmission effect can be achieved through the drive rod 302b. Then, when the motor 302 is working, it can drive the conveyor belt 301 to move.

[0030] Specifically, the upper side wall of the machine base 1 is provided with a transverse material feeding groove 101, the front and rear side walls of the material feeding groove 101 are provided with side grooves 102, and the upper side wall at the end of the side groove 102 is provided with a top groove 103. The material feeding groove 101, the side groove 102 and the top groove 103 are all connected. The bottom side wall of the machine base 1 is also equipped with a support base 2, that is, the machine base 1 is placed on the ground through the support base 2.

[0031] Furthermore, one end of the conveyor belt 301 is set inside the side trough 102 and is separated from the inner wall of the side trough 102. The other end of the conveyor belt 301 extends into the material feeding trough 101. The conveyor belt 301 is set in two sections, which are respectively set on the side troughs 102 on the front and rear sides of the material feeding trough 101, thereby achieving the effect of reducing costs.

[0032] The motor 302 is installed in the top groove 103, and a frame 302a is also fixedly installed on the outer wall of the motor 302. That is, the motor 302 is fixedly installed in the top groove 103 through the frame 302a, and the output shaft of the motor 302 is connected to the drive rod 302b through a coupling, thereby achieving the transmission effect.

[0033] The operation process of this embodiment is as follows: Start the motor 302. When the motor 302 is working, the drive rod 302b on its output shaft will rotate accordingly. When the drive rod 302b rotates, the conveyor belt 301 connected to it can move. Then, the carrier 401 is placed into the belt groove 301a of the conveyor belt 301. At this time, the carrier 401 can be transported to the location of the detection component 5. After the control motherboard on the carrier 401 is detected by the detection component 5, the motor 302 works again, carrying the control motherboard that has completed the detection out of the location of the detection component 5. The control motherboard on the next carrier 401 is detected in the same way. At the same time, the carrier 401 and its control motherboard can be taken out of the conveyor belt 301. Then, the carrier 401 is placed with a new control motherboard to be detected and flows back to the input end of the conveyor belt 301. This process is repeated to achieve the effect of cyclic detection.

[0034] Example 2

[0035] Please see Figure 4 Based on embodiment 1, a support component 4 is also provided. The support component 4 includes a carrier 401 placed on the conveyor belt 301. The carrier 401 is connected to the limiting post 301b on the conveyor belt 301 through the limiting hole 401d thereon, thereby achieving the effect of positioning the carrier 401 and preventing the carrier 401 from shifting when the conveyor belt 301 moves. The carrier 401 is also provided with a positioning element 402. The positioning effect of the control board is achieved by moving the positioning element 402. The structure is simple and easy to operate.

[0036] Specifically, multiple grooves 301a are equally spaced on the conveyor belt 301, and a limit post 301b is fixedly installed at the corner of the groove 301a. Limit holes 401d are opened at the four corners of the carrier 401, and the limit holes 401d are inserted into the limit posts 301b, thereby realizing the assembly between the carrier 401 and the conveyor belt 301.

[0037] The upper side wall of the carrier 401 is also provided with a plate groove 401a for controlling the placement of the main board, and semi-circular grooves 401b are also provided on the front and rear side walls of the plate groove 401a. A shaft hole 401c is provided on the bottom side wall of the semi-circular groove 401b, and the positioning member 402 is set in the semi-circular groove 401b.

[0038] Furthermore, the positioning component 402 includes a rod 402a fixed in the shaft hole 401c. From bottom to top, a baffle 402c, a spring 402d, and a rod sleeve 402b are sequentially sleeved in the rod 402a. When the baffle 402c is subjected to a lateral force, it can be pushed into the semi-circular groove 401b for storage. A soft pad 402e that contacts the control main board is also adhered to the bottom side wall of the baffle 402c.

[0039] The operation process of this embodiment is as follows: When assembling the control motherboard onto the carrier 401, first press down on the baffle 402c in the positioning member 402 and push it outwards to move the baffle 402c away from the slot 401a. At this time, the control motherboard can be placed into the slot 401a. After the control motherboard is fully inside the slot 401a, push the baffle 402c in the opposite direction to make it re-enter the slot 401a. At this time, the baffle 402c is located above the control motherboard, and is supported by the soft pad 4 on its bottom side wall. 02e contacts the control motherboard to prevent damage to the control motherboard. During this process, the spring 402d is always in an extended state to ensure that the baffle 402c is always pushed downward. This completes the assembly between the control motherboard and the carrier 401. After the assembly is completed, the carrier 401 is placed into the groove 301a of the conveyor belt 301. The limiting holes 401d on the four corners of the carrier 401 are inserted into the limiting posts 301b in the groove 301a, thereby ensuring that the carrier 401 does not move during the conveying process.

[0040] Example 3

[0041] Please see Figure 5 Based on Embodiments 1 and 2, a detection component 5 is also provided. The detection component 5 includes a mounting frame 501 mounted on the machine base 1. An electric push rod 503 is suspended at the center of the mounting frame 501. A probe plate 504 is also installed at the end of the electric push rod 503. The electric push rod 503 is used to push the probe plate 504 to move up and down, and the probe plate 504 is used to connect to the control main board on the carrier 401 and to detect it.

[0042] Specifically, a mounting groove 104 is provided at the center of the machine base 1, and connecting plates 502 are fixedly installed at both ends of the mounting frame 501. The mounting frame 501 is fixedly connected to the mounting groove 104 through the connecting plates 502, and a frame groove 501a is provided at the center of the mounting frame 501.

[0043] Furthermore, a lifting frame 503a is fixedly installed on the outer wall of the electric push rod 503, and the electric push rod 503 is connected to the frame groove 501a through the lifting frame 503a. The telescopic end of the electric push rod 503 is set vertically downward.

[0044] A proximity sensor 501b is embedded in the side of the electric push rod 503 and on the bottom side wall of the mounting bracket 501. The proximity sensor 501b is used to detect whether there is a carrier 401 on the conveyor belt 301 below.

[0045] The operation process of this embodiment is as follows: When the proximity sensor 501b detects an object approaching signal, it is determined that the carrier 401 carrying the control motherboard has moved to directly below the detection component 5. At this time, the motor 302 stops working, the conveyor belt 301 stops conveying, and then the electric push rod 503 in the detection component 5 moves down with the probe plate 504 and connects with the control motherboard to realize the test of the control motherboard. After the test is completed, the electric push rod 503 retracts and moves up with the probe plate 504.
