[0029] Embodiment

[0030] During the production process of the drive motor system of new energy vehicles, it is necessary to perform the operation of selecting gaskets for the shafting of the gearbox group. In order to ensure that the selected gaskets are not omitted or misinstalled into the gearbox group, the previous method was to conduct manual inspection or photo inspection before assembling the gearbox to ensure that the gaskets are not omitted or misinstalled. However, manual inspection has risks such as missed inspection or misjudgment in an environment where the operator is fatigued or physically uncomfortable. Photo inspection has risks due to the close color of the gasket and the housing, or due to disadvantages such as the inspection procedure and low equipment recognition accuracy.

[0031] In the solution of this application, a method of using a detection component to measure the thickness of the gasket is adopted. Its advantage is that it can avoid the weaknesses of manual inspection and photo inspection, ensure that the gaskets are not omitted or misinstalled, and thus avoid the risks of broken teeth of the bearing, cracked housing, and broken bearing leading to power loss of the vehicle in the motor system.

[0032] As Figures 1 - 4 shown, in a first aspect, the embodiment of this application provides a mechanism for detecting the thickness of the gasket 102, including: a gearbox group housing 100, which is configured with an assembly cavity 101, and the assembly cavity 101 is configured to be used for assembling the gasket 102; a detection component, including a driving structure and a detection piece, the detection piece is connected to the driving structure for detecting the gasket 102, and the driving structure is used to drive the detection piece to approach or move away from the gasket 102 in the up and down direction.

[0033] Exemplarily, the detection scheme of the mechanism for detecting the thickness of the gasket 102 for the gasket 102 is not limited to the drive motor system of new energy vehicles, and it is also applicable to any gearbox group assembly line operation that requires gasket selection process, such as the reducer of new energy vehicles, the transmission of fuel vehicles (MT / AMT / AT / DCT / CVT, etc.).

[0034] It should be noted that the driving method of the driving structure can be driven by a driving motor or by a robot, and no specific limitation is made here, as long as it can make the detecting member approach or move away from the upper surface of the gasket 102 in the vertical direction.

[0035] In the above implementation process, before the gearbox housing 100 is assembled, the driving structure drives the detecting member to move to the gasket 102 and makes the detecting member contact the upper surface of the gasket 102 to obtain the actual thickness of the gasket 102. If the thickness of the gasket 102 is zero or far exceeds the thickness range of the gasket 102 calculated and set by the equipment program, it is defaulted that the gasket 102 is not installed or misinstalled. On the contrary, if the gasket 102 is not installed or misinstalled, the weaknesses of manual inspection and photographic inspection can be avoided, the occurrence of defective products can be effectively reduced, and the durability and reliability of the product can be improved.

[0036] In some embodiments, the detecting member includes a probe group 400, and at least one probe group 400 is configured. The detecting member can be set as the probe group 400, which has high detection accuracy, can realize the detection of at least one gasket 102, effectively reduce the risk of the gasket 102 not being installed or misinstalled in the product, can improve the gasket selection efficiency by 100%, and improve the qualified rate.

[0037] Exemplarily, the principle of the probe group 400 is to know the height of the assembly cavity 101 and the thickness range of the gasket 102 required initially by the system, and then measure the height from the surface of the gasket 102 to the upper end of the assembly cavity 101 by the probe group 400 of the present application, indirectly calculate the thickness of the gasket 102, and compare it with the thickness range of the gasket 102 required initially by the system, so as to determine whether there is misinstallation or non-installation.

[0038] In some embodiments, when a plurality of probe groups 400 are configured, the plurality of probe groups 400 are distributed at intervals along the periphery of the driving structure. It can be used to detect gaskets 102 of different specifications, improve the detection efficiency, can avoid the weaknesses of manual inspection and photographic inspection, effectively reduce the occurrence of defective products, and improve the durability and reliability of the product.

[0039] Exemplarily, the probe group 400 includes a plurality of high-precision probes (for example, three high-precision probes), and the high-precision probe includes a laser displacement sensor. Of course, the high-precision probe can also be a contact displacement sensor or other forms of sensors, etc.

[0040] It can be understood that when the probe group 400 contacts the upper surface of the gasket plate for measurement, during the measurement process, the driving structure and the gasket 102 are both in a static state and there is no relative movement between the two.

[0041] In some embodiments, the detection accuracy of the probe group 400 is not less than 1 um. With high detection accuracy, it can detect at least one gasket 102, effectively reducing the risk of missing or misplacing the gasket 102 of the product, improving the gasket selection efficiency by 100%, and increasing the qualification rate.

[0042] In some embodiments, the driving structure includes a driving member 200 and a supporting member 300. The driving member 200 is connected to the supporting member 300, and the side of the supporting member 300 facing away from the driving member 200 is connected to the detecting member.

[0043] Exemplarily, the driving member 200 includes but is not limited to a robotic arm. The driving member 200 is used to connect to a robot. The supporting member 300 includes but is not limited to a supporting block, and the detecting member is connected to the supporting block; in other embodiments, the driving member 200 can also be a driving motor. The supporting member 300 is connected to the driving motor, and the supporting member 300 can be installed on a slide rail. For example, the supporting member 300 is provided with a first gear, and the slide rail is provided with a second gear. The first gear meshes with the second gear. By driving the driving member 200, the supporting member 300 can be moved relative to the slide rail, and finally the detecting member can be moved closer to or farther away from the gasket 102.

[0044] In the above implementation process, the driving member 200 drives the detecting member to move through the supporting member 300, which can realize the automatic detection of the gasket 102, avoid the weaknesses of manual inspection and photographic inspection, effectively reduce the occurrence of defective products, and improve the durability and reliability of the product.

[0045] In some embodiments, the supporting member 300 is connected to the driving member 200 by one of screwing, riveting, and bonding. The connection method is simple and convenient, which is beneficial to the replacement of the detecting member, realizes the detection of gaskets 102 of different models, and improves the applicability of the product.

[0046] In some embodiments, the detecting member is connected to the supporting member 300 by one of screwing, riveting, and bonding.
