[0002] An automotive domain controller is a new type of automotive electronic controller, which can enable a vehicle to have the capabilities of multi-sensor fusion, positioning, path planning, and decision-making control. A shrapnel 2 is usually installed on the shell 1 of the automotive domain controller. The shrapnel 2 includes a shrapnel body 2-1 for fixedly connecting with the shell 1 of the automotive domain controller and a plurality of strip-shaped contact arms 2-2 for electrically contacting with electronic components. The free end of each strip-shaped contact arm 2-2 is provided with an upwardly turned-out bent portion, and the bottom surface of each bent portion is the electrical contact surface 2-21 for electrically contacting with the electronic components (for example, as Figure 1 and 2 shown). Since the main function of the shrapnel 2 on the shell 1 of the automotive electronic controller is to conduct static electricity to protect the electronic devices inside the controller, so as to improve the reliability and stability of the controller. Therefore, when producing the shell of the automotive domain controller, it is necessary to conduct quality inspection on the installation height of the shrapnel on the shell of the automotive domain controller. The automotive industry requires that the allowable error range of the shrapnel installation height is ±0.3 mm to ensure good electrical contact of the shrapnel on the shell of the automotive domain controller.

[0032] Embodiment

[0033] First, please refer to Figure 1 and Figure 2 as shown: A shrapnel 2 is installed on the housing 1 of the automotive domain controller in this embodiment. The shrapnel 2 includes a shrapnel body 2-1 for fixedly connecting with the housing 1 of the automotive domain controller and several (6 are shown in the figure) strip-shaped contact arms 2-2 for making electrical contact with electronic components. The free end of each strip-shaped contact arm 2-2 is provided with an upwardly turned-out bending portion, and the bottom surface of each bending portion is the electrical contact surface 2-21 for making electrical contact with the electronic component. In order to ensure good electrical contact between each electrical contact surface 2-21 and the electronic component at the corresponding position, after installing the shrapnel 2, it is necessary to detect whether the installation height of the shrapnel 2 is within the required error range. The allowable error range of this installation height in the automotive industry is limited to ±0.3mm.

[0034] In order to realize the efficient, accurate and low-cost detection of the installation height of the shrapnel on the housing of the automotive domain controller, a device for detecting the installation height of the shrapnel on the housing of the automotive domain controller provided in this embodiment is as shown in Figure 3 and Figure 4 as shown, which includes a detection platform 3. On the top of the detection platform 3, there are a conductive block mounting seat 4 and several reference plane positioning posts 5. On the top surface of the conductive block mounting seat 4, there are fixedly installed conductive blocks 6 respectively corresponding to the electrical contact surfaces 2-21 of the shrapnel 2 to be detected. All the conductive blocks 6 are respectively electrically connected (i.e., 6 conductive blocks are respectively corresponding and electrically connected to the 6-channel relay input terminals of the PLC controller) to the relay input terminals (not shown in the figure) of the PLC controller with multi-channel relay input through wires 7. And the top surfaces of all the reference plane positioning posts 5 are located on the same horizontal plane. The height difference between the top surface of each conductive block 6 and the top surface of the reference plane positioning post 5 is equal to the standard height difference between the electrical contact surface 2-21 of the shrapnel 2 on the housing 1 of the automotive domain controller to be detected and the reference plane (the reference plane refers to the installation surface of the PCB board of the automotive domain controller to be detected inside the housing of the automotive domain controller to be detected). In addition, at the bottom of the conductive block mounting seat 4, there is a lifting mechanism capable of driving the conductive block 6 to move up and down linearly, and the maximum distance of the linear movement of the conductive block 6 up and down is equal to the maximum allowable error of the installation height of the shrapnel 2 on the housing 1 of the automotive domain controller to be detected (set to 0.58mm in this embodiment, which is slightly stricter than the 0.6mm requirement in the automotive industry).

[0035] The utility model realizes the automatic detection of the installation height of the elastic sheet 2 on the automotive domain controller housing 1 through the following steps: by providing a reference plane positioning post 5 and conductive blocks 6 that are in one-to-one correspondence with the electrical contact surfaces 2-21 on the elastic sheet 2 to be detected, and according to the requirements of industry standards, the height difference between the top surface of the conductive block 6 and the top surface of the reference plane positioning post 5 is limited within an error range of the standard height difference of ±0.3 mm (in this embodiment, it is limited to ±0.29 mm). Then, when each conductive block 6 is located at the upper limit position and the lower limit position respectively, the PLC controller detects whether there is current passing through the relay connected to the conductive block 6 to identify whether the conductive block 6 forms an electrical contact with the electrical contact surface 2-21 on the elastic sheet 2 to be detected. If there is current passing through, it indicates that an electrical contact is formed; if there is no current passing through, it indicates that no electrical contact is formed. Only when an electrical contact can be formed when located at the upper limit position and no electrical contact can be formed when located at the lower limit position, can it be determined that the height of the electrical contact surface 2-21 at this detection position meets the requirements. And only when the heights of all electrical contact surfaces 2-21 meet the requirements, can it be determined that the installation height of the elastic sheet 2 to be detected is qualified. Thus, it can be seen that through the ingenious structural design of the utility model, not only can the installation height of the elastic sheet 2 on the automotive domain controller housing 1 be automatically detected, but also the detection efficiency is high, the detection accuracy and consistency are good, and the cost is low and the degree of automation is high, which can meet the requirements of automated mass production detection and has significant practical value.

[0036] In the utility model, the number and installation positions of the reference plane positioning posts 5 correspond one-to-one with the number and positions of the mounting holes 1-1 for mounting the PCB board on the inner wall of the automotive domain controller housing 1 to be detected. Please refer to Figure 2 As shown, in this embodiment, there are 4 mounting holes 1-1 for mounting the PCB board on the inner wall of the automotive domain controller housing 1 described. Therefore, in this embodiment, the number of the reference plane positioning posts 5 is 4, and the installation positions correspond one-to-one with the 4 mounting holes 1-1. Please refer to Figure 2 and Figure 3 As shown. By providing the reference plane positioning posts 5, it is beneficial to determine the installation positions and standard heights of the conductive blocks 6.

[0037] Please refer to Figure 4As shown, in this embodiment, the lifting mechanism is a jacking cylinder 8. The jacking cylinder 8 is vertically upwardly disposed at the bottom of the conductive block mounting seat 4, and the output end of the jacking cylinder 8 vertically passes through the detection platform 3 and then is connected to the conductive block mounting seat 4. The specific implementation manner of this embodiment is: a connecting block 9 is fixedly provided at the bottom of the conductive block mounting seat 4, and the output end of the jacking cylinder 8 is fixedly connected to the bottom of the connecting block 9. By driving the lifting movement of the connecting block 9 by the jacking cylinder 8, the conductive block mounting seat 4 fixedly connected to the connecting block 9 can be driven to perform a lifting movement, and further the conductive block 6 fixed on the conductive block mounting seat 4 can be driven to perform a lifting movement. It should be noted here that the stroke of the lifting movement of the conductive block 6 is equal to the maximum allowable error of the installation height of the elastic piece 2 on the outer shell 1 of the automotive domain controller to be detected (limited to 0.58 mm in this embodiment).

[0038] Please refer to Figures 4 to 6 As shown, in this embodiment, on the left and right sides of the connecting block 9, limiting seats 10 are respectively fixedly provided. The inner side of the limiting seat 10 is provided with a limiting groove 10-1 with an opening facing the connecting block 9. The left and right ends of the connecting block 9 are respectively located in the corresponding limiting grooves 10-1 and can move up and down linearly in the limiting grooves 10-1 under the drive of the jacking cylinder 8, and the maximum distance of the linear up and down movement of the connecting block 9 in the limiting grooves 10-1 is equal to the maximum allowable error of the installation height of the elastic piece 2 on the outer shell 1 of the automotive domain controller to be detected (0.58 mm in this embodiment. Since this stroke distance is very small, the operating space of the connecting block 9 in the limiting groove 10-1 cannot be clearly shown in the figure).

[0039] In this embodiment, the limiting seat 10 includes a lower limiting seat 10-2 horizontally fixedly provided on the top of the detection platform 3 and an upper limiting seat 10-3 horizontally fixedly provided on the top of the lower limiting seat 10-2. The upper part of the inner side of the lower limiting seat 10-2 is provided with a 90-degree notch, and the bottom of the upper limiting seat 10-3 covers the top of the 90-degree notch to form the limiting groove 10-1.

[0040] Please refer to Figure 3 、 Figure 4 and Figure 6As shown in the figure, in this embodiment, a product pressing mechanism 11 is further provided on the top of the detection platform 3. The product pressing mechanism 11 includes a lifting cylinder 11-1, a clamping head 11-2, and a pressing arm 11-3. One end of the clamping head 11-2 is fixedly connected to the output shaft of the lifting cylinder 11-1, and the other end of the clamping head 11-2 is fixedly connected to the pressing arm 11-3. By driving the pressing arm 11-3 to descend through the lifting cylinder 11-1, the pressing arm 11-3 can be used to press and limit the outer shell 1 of the automotive domain controller being detected. When the detection of the outer shell 1 of the automotive domain controller is completed, the pressing arm 11-3 can be driven to rise through the lifting cylinder 11-1 to separate from the outer shell 1 of the automotive domain controller, thereby avoiding hindering the loading and unloading of the outer shell 1 of the automotive domain controller.

[0041] Please refer to again Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown in the figure, in this embodiment, a plurality of product limit columns 12 are also vertically provided around the top of the detection platform 3 to play a role in guiding and limiting the placement position of the outer shell 1 of the automotive domain controller.

[0042] Please refer to again Figure 3 As shown in the figure, the device in this embodiment further includes an electric control box 13. The detection platform 3 is located on the top of the electric control box 13. A touch screen 13-1 is provided on the electric control box 13, and the signal input end of the touch screen 13-1 is connected to the signal output end of the PLC controller (not shown in the figure). The touch screen 13-1 and the PLC controller can be integrated into one body. For example: an industrial touch all-in-one machine of the model MM-40MT-12MT-700-ES-B from Delta Company can be directly selected, which has 24 X-point input terminals, 16 Y-point relay output terminals, and a 7-inch touch screen.

[0043] In a preferred solution, a qualified indicator light 13-2 is further provided on the electric control box 13. The qualified indicator light 13-2 is electrically connected to the PLC controller (specifically, a Y-point relay output terminal of the PLC controller). Through the qualified indicator light 13-2, the detection result of the PLC controller can be intuitively indicated as qualified.

[0044] As a further preferred solution, a buzzer 13-3 is further provided on the electric control box 13. The buzzer 13-3 is electrically connected to the PLC controller (specifically, a Y-point relay output terminal of the PLC controller). When the detection result of the PLC controller is unqualified, it gives a buzzer alarm prompt.

[0045] As a further preferred solution, a two-handed start button 13-4 is also provided on the electric control box 13. The two-handed start button 13-4 is electrically connected to the PLC controller (specifically, the PLC operation switch). By setting the two-handed start button 13-4, the risk of accidental start caused by collision or other reasons can be avoided.

[0046] In a preferred solution, handles 13-5 are also provided on both sides of the electric control box 13 to facilitate the movement of the overall device.

[0047] The usage method of the device of the present utility model for detecting the installation height of the elastic piece on the housing of the automotive domain controller is as follows:

[0048] Please refer to Figures 6 to 8 as shown: Place the bottom of the housing 1 of the automotive domain controller to be detected downward on the tops of the 4 reference plane positioning posts 5, and make the end faces of the 4 mounting holes 1-1 on the inner wall of the housing 1 of the automotive domain controller for mounting the PCB board fit with the top surfaces of the corresponding reference plane positioning posts 5, and make the 6 electrical contact surfaces 2-21 on the elastic piece 2 of the housing 1 of the automotive domain controller correspond to the 6 conductive blocks 6 one by one. Then, drive the pressing arm 11-3 to descend through the lifting cylinder 11-1, so that the pressing arm 11-3 presses and limits the housing 1 of the automotive domain controller;

[0049] In the initial state, the conductive block 6 is located at the lower limit position (that is, the connecting block 9 at the bottom of the conductive block 6 contacts the bottom wall of the limiting groove 10-1). At this time, if the conductive block 6 does not contact the electrical contact surface 2-21 on the elastic piece 2, then the conductive block 6 and the electrical contact surface 2-21 on the elastic piece 2 cannot form a conducting circuit, and no current signal will be input to the PLC controller through the relay input terminal connected in series with it through the wire 7. Therefore, the PLC controller can identify that the corresponding conductive block 6 does not form an electrical contact with the electrical contact surface 2-21 on the elastic piece 2 to be detected by the absence of a current signal input. On the contrary, if the conductive block 6 contacts the electrical contact surface 2-21 on the elastic piece 2, then the conductive block 6 and the electrical contact surface 2-21 on the elastic piece 2 will form a conducting circuit, and a current signal will also be input to the PLC controller through the relay input terminal connected in series with it through the wire 7. Therefore, the PLC controller can identify that the corresponding conductive block 6 has formed an electrical contact with the electrical contact surface 2-21 on the elastic piece 2 to be detected by the presence of a current signal input; In this way, the PLC controller can detect and obtain the current conduction and non-conduction results of each conductive block 6 when it is located at the lower limit position;

[0050] Then, make the conductive block 6 rise to the upper limit position (that is, the connecting block 9 at the bottom of the conductive block 6 contacts the top wall of the limiting groove 10-1) through the jacking cylinder 8. Then, by the same principle, the PLC controller can detect and obtain the current conduction and non-conduction results of each conductive block 6 when it is located at the upper limit position;

[0051] Only when the conductive block 6 is in the upper limit position can it contact the electrical contact surface 2-21 on the elastic piece 2 to form a conducting circuit, and when the conductive block 6 is in the lower limit position, it cannot contact the electrical contact surface 2-21 on the elastic piece 2 to form a conducting circuit, then it is judged that the electrical contact surface 2-21 corresponding to the conductive block is within the qualified height range; only when the heights of all the electrical contact surfaces 2-21 are within the qualified range can it be determined that the installation height of the elastic piece 2 is qualified, and thus the PLC controller controls the qualified indicator light 13-2 to light up; if when the conductive block 6 is in the upper limit position, it can contact the electrical contact surface 2-21 on the elastic piece 2 to form a conducting circuit, and when it is in the lower limit position, it can also contact the electrical contact surface 2-21 on the elastic piece 2 to form a conducting circuit, then it is judged that the height of the electrical contact surface 2-21 corresponding to the conductive block is too high and unqualified; if when the conductive block 6 is in the upper limit position, it cannot contact the electrical contact surface 2-21 on the elastic piece 2 to form a conducting circuit, and when it is in the lower limit position, it cannot also contact the electrical contact surface 2-21 on the elastic piece 2 to form a conducting circuit, then it is judged that the height of the electrical contact surface 2-21 corresponding to the conductive block is too low and unqualified; the PLC controller outputs the serial number and detection result of the electrical contact surface 2-21 corresponding to each conductive block 6 to the touch screen 13-1 in real time to visually display the height detection result of each electrical contact surface 2-21; as long as the height detection result of one electrical contact surface is unqualified, it is determined that the installation height of the elastic piece 2 is unqualified, and the PLC controller activates the buzzer 13-4 for alarm prompt.

[0052] As can be seen from the above, through the ingenious structural design of the present utility model, not only can the installation height of the elastic piece 2 on the automotive domain controller housing 1 be automatically detected, but also the detection efficiency is high, the detection accuracy and consistency are good, and the cost is low and the degree of automation is high, which can meet the requirements of automated mass production detection, and the practical value is remarkable.

[0053] Finally, it is necessary to point out here that: the above description is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
