[0002] The pre-assembly of the electronic control unit ECU production includes the PCBA PIN insertion process. At present, the verticality of the PIN cannot be detected after the PCBA PIN insertion station is offline. If the verticality deviates during the PIN insertion process, the PIN will not extend during the subsequent end cover press-fitting process, resulting in product scrapping. If a batch of PINs do not extend, it will cause errors in the assembly process and the production line will stop.

[0017] The utility model is now further described with reference to the accompanying drawings.

[0018] See also Figure 1 , Figure 2 and Figure 3 The utility model is a tool for detecting the verticality of PIN connection of an ECU, comprising a bottom plate, a vertical plate, a limit block, a lifting bracket, an upper tooling, a lower tooling, and a centering tooling. A lower tooling 10 and a centering tooling 8 are installed on the bottom plate 11, a PCBA 13 is installed on the top of the lower tooling 10, a limit block 4 is installed on the front surface of the vertical plate 6, the middle part of the lifting bracket passes through the mounting hole of the limit block 4, an upper tooling 5 is installed on the bottom of the lifting bracket, a centering hole 51 and a limit groove 52 are provided on the surface of the upper tooling 5, the position of the centering hole 51 corresponds to the position of the centering tooling 8, and the position of the limit groove 52 corresponds to the design position of the PIN pin 15 of the PCBA 13.

[0019] The lifting bracket includes an upper connecting plate 2, a lower connecting plate 14, and a guide shaft 3. The middle part of the guide shaft 3 passes through the mounting hole of the limit block 4. The upper connecting plate 2 and the lower connecting plate 14 are respectively installed at the upper and lower ends of the guide shaft 3. The bottom of the lower connecting plate 14 is installed with an upper tooling 5.

[0020] The centering tool 8 is provided to detect the verticality of the upper tool 5 and the guide shaft 3, so that the upper tool 5 remains parallel to the lower tool 9, thereby ensuring that the limit groove 52 is located directly above the designed position of the PIN needle 15 of the PCBA 13, thereby ensuring the accuracy of the test result.

[0021] The limit block 4 ensures the stability and linearity of the guide shaft 3 during movement.

[0022] A handle 1 is provided on the front side of the upper connecting plate 2 for easy use.

[0023] The shape of the upper fixture 5 and the size of the limit groove 52 match the ECU model corresponding to the PCBA 13. The top structure of the lower fixture 10 matches the ECU model corresponding to the PCBA 13. The shape structure of the upper fixture 5 and the limit groove 52 can be designed and adjusted according to the structure and verticality requirements of the PCBA 13 of different models of ECUs.

[0024] The surface of the lower tooling 10 is provided with a positioning pin 9, which matches the positioning hole on the surface of the PCBA 13 to limit the installation position of the PCBA 13. The lower tooling 10 can be adjusted according to different PCBA models to design a lower tooling 10 suitable for different models of ECUs.

[0027] When the utility model is working, the PCBA 13 is fixed on the lower tooling 10, and the placement position of the PCBA 13 is constrained by the positioning pin 9, and the handle 1 is pushed to move the guide shaft 3 in the limit block 4, thereby driving the upper tooling 5 to move downward. The centering hole 51 on the upper tooling 5 passes through the centering tooling 8, and all the plugged PIN pins 15 on the PCBA 13 completely pass through the limit slots 52 on the upper tooling 5, then the verticality of the PIN pin plugging is judged to be qualified; if some of the PIN pins 15 do not pass through the limit slots 52 on the upper tooling 5, or some of the PIN pins 15 interfere with the upper tooling 5, then the verticality of the PIN pin plugging is judged to be unqualified.

[0028] The utility model can quickly and accurately detect the verticality of PIN pin insertion, identify unqualified products, reduce the impact on subsequent processes, reduce production waste, and save costs such as materials and labor; by adjusting the shape of the upper tooling, the limit groove and the position of the lower tooling, the verticality detection of the PIN pins of the PCBA corresponding to different models of ECU can be met, and the versatility is high. The utility model has the advantages of simple structure, low cost, strong practicality, convenient operation, and high detection efficiency, and can be applied to the verticality screening of PIN pins of large quantities of PCBA.
