Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a step adjustment device 1, which is suitable for adjusting the splicing step difference between multiple display light panels 2 spliced ​​in sequence, and can automatically adjust the splicing step difference between adjacent display light panels 2, effectively improving the installation and debugging efficiency and the consistency of work quality.

[0026] The step difference adjustment device 1 includes a step difference measurement mechanism 10, a control circuit 20 and an adjustment actuator 30 which are electrically connected in sequence. The step difference measurement mechanism 10 is configured to measure the splicing step difference between adjacent display light panels 2, and output the measurement result to the control circuit 20 in the form of an electrical signal. The control circuit 20 is configured to output a control electrical signal to the adjustment actuator 30 according to the measurement result to control the adjustment actuator 30 to perform an adjustment operation. The adjustment actuator 30 adjusts the position of the adjacent display light panels 2 according to the control electrical signal to change the splicing step difference between the adjacent display light panels 2, so that the splicing step difference between the adjacent display light panels 2 is adjusted to within an allowable range or even eliminated.

[0027] Compared with the related art, the step adjustment device 1 provided in the embodiment of the present application directly measures the splicing step difference through the step measurement mechanism 10, and then controls the adjustment actuator 30 to perform the adjustment operation according to the measurement result, so as to change the relative position and splicing step difference between adjacent display light panels 2, so that the splicing step difference between adjacent display light panels 2 is adjusted to within the allowable range or even eliminated; the above-mentioned measurement and adjustment process is implemented based on an automated structure, without the need for manual operation, and can eliminate the consistency differences caused by manual operation errors, with higher installation and debugging efficiency and operation quality consistency.

[0028] The structure of the step difference measurement mechanism 10 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the step difference measurement mechanism 10 may include a depth camera 11 or a ranging sensor. The depth camera 11 can capture an image of the display light board 2, and measure the distance between the display light board 2 and the depth camera 11 based on the captured image, and then subtract the distance between two adjacent display light boards 2 and the depth camera 11 to obtain the splicing step difference between adjacent display light boards 2. The ranging sensor can measure the distance between it and the display light board 2, and then subtract the distance between two adjacent display light boards 2 and the ranging sensor to obtain the splicing step difference between adjacent display light boards 2; the type of ranging sensor can be determined according to actual needs, and can be, for example, an infrared ranging sensor, an ultrasonic ranging sensor, a laser ranging sensor, etc., and the embodiments of the present application do not limit this.

[0029] The circuit structure of the control circuit 20 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the control circuit 20 may include a comparator, which is configured to compare the size of the measurement result and the step difference threshold. When the measurement result is greater than the step difference threshold, it indicates that the splicing step difference between adjacent display light panels 2 is large and needs to be reduced. At this time, the control circuit 20 can send a control electrical signal to the adjustment actuator 30 to control the adjustment actuator 30 to perform the adjustment action; and when the measurement result does not exceed the step difference threshold, it indicates that the splicing step difference between adjacent display light panels 2 is as expected and no adjustment is required. At this time, the control circuit 20 does not send a control electrical signal to the adjustment actuator 30, and does not adjust the position between adjacent display light panels 2.

[0030] The structure of the adjustment actuator 30 can be determined according to actual needs, so as to match the position of the adjustment display light board 2, and the embodiments of the present application do not limit this. In some embodiments, multiple display light boards 2 can be installed on the back panel 3 by fixing screws 4 respectively, and the back panel 3 can be provided with a threaded hole 301 that is threadedly connected to the fixing screw 4, and the fixing screw 4 is fixedly connected to the display light board 2 after passing through the threaded hole 301. Here, the adjustment actuator 30 may include an electric screwdriver 31, which is configured to drive the fixing screw 4 to advance and retreat in a spiral at the threaded hole 301, and the display light board 2 connected thereto is driven by the fixing screw 4 to advance and retreat synchronously, so that the display light board 2 approaches or moves away from the back panel 3, so as to change the distance between the display light board 2 and the back panel 3, and then change the splicing step difference between adjacent display light boards 2.

[0031] In some examples, the adjustment actuator 30 may include a plurality of electric screwdriver groups 31. The plurality of electric screwdriver groups 31 are equal in number to the plurality of display light panels 2 and are arranged one-to-one, so that each display light panel 2 is provided with an electric screwdriver group 31; wherein each electric screwdriver group 31 includes at least one electric screwdriver 31. In this way, when it is necessary to adjust the position of a certain display light panel 2, the electric screwdriver group 31 corresponding to the display light panel 2 can be controlled to perform the adjustment operation accordingly to achieve the respective corresponding adjustment purposes.

[0032] For example, the display light board 2 can be mounted on the back plate 3 by means of a plurality of fixing screws 4; accordingly, the electric screwdriver 31 group can include a plurality of electric screwdrivers 31, and the plurality of fixing screws 4 and the plurality of electric screwdrivers 31 are equal in number and arranged one-to-one. In this way, an electric screwdriver 31 is arranged corresponding to each fixing screw 4, and the electric screwdriver 31 can be controlled to directly drive the corresponding fixing screw 4 to advance and retreat in a spiral, thereby achieving the purpose of one-to-one drive control and adjustment.

[0033] In some examples, the adjustment actuator 30 may include a transverse feed module 40. The electric screwdriver 31 is disposed on the transverse feed module 40, and the transverse feed module 40 is configured to drive the electric screwdriver 31 to move so that the electric screwdriver 31 switches positions between different display light panels 2. In this way, the transverse feed module 40 can be used to quickly move the electric screwdriver 31 to the display light panel 2 to be adjusted, and then perform an adjustment operation on the display light panel 2, thereby increasing the feed operation range of the electric screwdriver 31. The type of the transverse feed module 40 can be determined according to actual needs, and can adopt one type or a combination of multiple types of structures such as a screw rod-guide rail slider structure, a linear motor-guide rail slider structure, an electric push rod-guide rail slider structure, and a telescopic cylinder-guide rail slider structure, and the present application embodiment does not limit this.

[0034] Exemplarily, the transverse feed module 40 can be extended along the splicing direction of the multiple display light panels 2 to drive the electric screwdriver 31 to reciprocate along the splicing direction of the multiple display light panels 2. For example, when the multiple display light panels 2 are spliced ​​in sequence along one direction, the transverse feed module 40 can be extended along the splicing direction; for another example, when the multiple display light panels 2 are spliced ​​in sequence along two directions, the transverse feed module 40 can be respectively extended along the two splicing directions.

[0035] The structure of the electric screwdriver 31 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some examples, the electric screwdriver 31 may include a screwdriver head and a driving element that drives the screwdriver head to rotate. The type of the driving element can be determined according to actual needs, and can be, for example, a rotary motor, a hydraulic rotary motor, etc., and the embodiment of the present application does not limit this.

[0036] In some embodiments, the step adjustment device 1 may further include a support base, which is configured to support a plurality of sequentially spliced ​​display light panels 2. By providing the support base, the plurality of sequentially spliced ​​display light panels 2 can be kept at the adjustment station so as to automatically measure and adjust the plurality of display light panels 2.

[0037] The above is a detailed introduction to the step adjustment device provided in the embodiment of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, based on the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
