[0040] Optionally, the second X-axis moving assembly includes a first ranging slider at the top of the third rangefinder, a second ranging slider at the top of the fourth rangefinder and a ranging X-axis guide rail, and the first ranging slider and the second ranging slider both slide in cooperation with the ranging X-axis guide rail.

[0042] Optionally, the first X-axis moving assembly further includes an X-axis driving element;

[0043] The second Y-axis moving assembly also includes a Y-axis driving element.

[0044] Working principle of the present invention:

[0045] In this embodiment, the first rangefinder is fixedly mounted on the bottom of the first substrate. In other embodiments, the first rangefinder can be movably arranged on the bottom of the first substrate as needed. Since the first rangefinder is fixed, the second rangefinder, the third rangefinder, and the fourth rangefinder can all be movable, and the distances between the four can be adjusted. Since the second rangefinder is arranged on the bottom of the second substrate, in this embodiment, the second rangefinder is fixed on the bottom of the second substrate, and the second substrate is connected to the second substrate through the first X-axis moving component. Therefore, the second substrate can be close to the first rangefinder or away from the first rangefinder along the X-axis direction. The linear guide rail in the first X-axis moving component is arranged on the first substrate, and the linear slider in the first X-axis moving component is arranged on the second substrate. Therefore, the second substrate can move relative to the first substrate in the X-axis direction, which can change the displacement of the second rangefinder and the third rangefinder relative to the first rangefinder in the X-axis direction.

[0046] Since the third rangefinder is connected to the bottom of the second substrate through the first Y-axis moving assembly, a linear guide rail of the first Y-axis moving assembly is provided on the second substrate, and a linear slider of the first Y-axis moving assembly is provided on the top of the third rangefinder, the third rangefinder can move along the Y-axis direction on the second substrate, and when the second substrate moves in the X-axis direction, both the third rangefinder and the second rangefinder move along the X-axis direction;

[0047] The fourth rangefinder is connected to the bottom of the first substrate through the second Y-axis moving component, a linear guide rail of the second Y-axis moving component is arranged on the first substrate, and a linear slider of the second Y-axis moving component is arranged on the top of the fourth rangefinder, so that the fourth rangefinder can move along the Y-axis direction on the linear guide rail of the first substrate, thereby adjusting the position of the fourth rangefinder relative to the first rangefinder in the Y-axis direction.

[0048] The top of the fourth rangefinder is respectively provided with a linear slider of a second Y-axis moving assembly and a second ranging slider through an installation structure. The second ranging slider can slide along the X-axis direction, and the linear slider of the second Y-axis moving assembly slides along the Y-axis direction, and the two do not interfere with each other. The first ranging slider and the second ranging slider are both located on the ranging X-axis guide rail, so that the third rangefinder maintains high linear accuracy when moving along the X-axis direction, and guides and accurately adjusts the distance between the third rangefinder and the fourth rangefinder.

[0049] The telescopic mechanism can be arranged on the frame or on the first substrate. When it is necessary to protect the corresponding rangefinder or camera mechanism, the corresponding telescopic mechanism can drive the shading plate to cover the output end of the corresponding rangefinder or camera mechanism to protect the corresponding detection end or lens. When it is necessary to use the corresponding rangefinder or camera mechanism, the telescopic mechanism can drive the corresponding shading plate away from the corresponding rangefinder detection end or the lens of the camera mechanism. The laser welding head and the camera mechanism are arranged on the frame to meet the processes of laser welding, positioning, detection, etc. after ranging. The camera mechanism can select a CCD camera unit. The CCD camera unit can align the pole position of the battery cell, adjust the variable distance measuring mechanism of this scheme according to specific requirements, that is, adjust the positions of the first rangefinder, the second rangefinder, the third rangefinder, and the fourth rangefinder, so that the heights of the four poles can be measured at one time, and the height requirements of the adjacent four poles can be detected to be consistent.

[0050] like Figure 2 As shown, the X-axis direction and the Y-axis direction are indicated by the marks. Figure 3 In FIG. 8 , the dotted line portion is the detection direction of the first rangefinder, the second rangefinder, the third rangefinder, and the fourth rangefinder. Figure 4 In the embodiment, the wavy structure on the guide rail is an accordion cover, which is used to keep the corresponding guide rail clean.

[0051] A cross-guide rail structure is used between the first rangefinder, the second rangefinder, the third rangefinder and the fourth rangefinder, that is, the four rangefinders. The distances of the four rangefinders in the X-axis direction and the Y-axis direction are changed simultaneously. In this way, the detection of four battery cells can be completed at the same time, and the number of times the detection axis moves is about half of the original structure, which shortens the non-operating time, effectively improves the detection efficiency of the equipment and reduces the equipment cycle.

[0052] The X-axis driving element and the Y-axis driving distance can both be composed of cylinders. The X-axis driving element can drive the linear slider of the first X-axis moving component to move along the corresponding linear guide toward the X-axis, and the Y-axis driving element can drive the linear slider of the second Y-axis moving component to move along the corresponding linear guide toward the Y-axis.

[0053] In addition, in a specific implementation, the first X-axis moving component, the second X-axis moving component, the first Y-axis moving component, and the second Y-axis moving component can all be linear modules.

[0054] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
