[0033] The specific embodiments shown below are intended to serve as a description of the various configurations of the subject technology and are not intended to represent the only configurations in which the subject technology can be practiced. The specific embodiments include specific details for the purposes of providing a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology can be practiced without

[0034] It can be understood that, in this paper, such as "first" and "second" and other relational terms are intended to distinguish one entity or operation from another entity or operation, and are not intended to imply or indicate any actual relationship or order between the entities or operations.

[0037] A positioning assembly 2 is arranged in the body 1, and the positioning assembly 2 positions the position of the PCB circuit board.

[0038] And a calibration assembly 3 is arranged in the body 1.

[0039] The calibration assembly 3 comprises detection modules 31 for detecting the PCB board, the detection modules 31 are two, the calibration assembly 3 further comprises a driving assembly 32 for driving the relative motion of the two detection modules 31, wherein the two detection modules 31 are respectively located on both sides of the driving assembly 32, and the driving assembly 32 drives the two detection modules 31 to move synchronously in opposite directions.

[0040] The positioning assembly 2 is used for positioning the PCB circuit board, and the specific structure of the positioning assembly 2 is not limited, and can be freely determined according to actual needs. The positioning assembly 2 is only used for positioning the position of the PCB circuit board, therefore, different positioning assemblies 2 should be designed according to different PCB circuit boards.

[0041] Synchronous movement in opposite directions means that the two detection modules 31 move simultaneously, the movement speed of the two detection modules 31 is equal and the movement direction is opposite. Usually, the movement track of the two detection modules 31 is reciprocating movement along the horizontal plane.

[0042] Referring to Figs. 4 to 6 As shown in the figure, in some embodiments, the driving assembly 32 comprises a gear 321, the detection modules 31 are each provided with a rack 322 engaged with the gear 321, and the racks 322 located at the two detection modules 31 are respectively located on both sides of the gear 321.

[0043] It can be understood that since the two racks 322 are engaged with the gear 321 simultaneously, the engagement transmission between the gear 321 and the rack 322 has a precise transmission ratio, therefore, the synchronous movement of the two detection modules 31 in opposite directions can be effectively ensured, and the movement precision of the detection modules 31 is improved.

[0044] In some embodiments, the driving assembly 32 further comprises a motor 323 driving the gear 321, the motor 323 is installed in the body 1, and the gear 321 is installed on the output shaft of the motor 323.

[0045] It can be understood that, in order to further improve the detection precision of the detection module 31, the motor 323 can be a servo motor 323. The motor 323 can be fixed in the body 1 by any means. For example, a mounting cavity for installing the motor 323 can be provided in the body 1, and the motor 323 can be fastened in the mounting cavity by screws or other fasteners.

[0046] In some embodiments, the detection module 31 comprises a plate body 324, the rack 322 is arranged on the lower side of the plate body 324, and a gap 325 accommodating the gear 321 is formed between the plate body 324 and the rack 322, and a part of the gear 321 is located in the gap 325.

[0047] It can be understood that the detection module 31 further comprises a detection element, which is an electronic element. The detection element can be installed on the plate body 324 by any means.

[0048] In some embodiments, the height of the gear 321 is equal to the thickness of the two racks 322 arranged in the detection module 31, and the bottom surface of one of the racks 322 is flush with the top surface of the other rack 322.

[0049] It can be understood that, since the two racks 322 are staggered up and down, that is, the meshing positions of the two racks 322 and the gear 321 are not the same, so that the same position of the gear 321 does not need to be meshed with the two racks 322 at the same time, effectively slowing down the wear of the gear 321, prolonging the service life of the gear 321.

[0050] Referring to Figs. 4 to 6 In some embodiments, the plate body 324 and the rack 322 are of an integral structure. The rack 322 can also be detachably connected and fixed to the plate body 324, for example, the rack 322 can be fixed to the plate body 324 by screws. It can be understood that, since the rack 322 and the plate body 324 are of an integral structure, the detection module 31 has higher movement precision, therefore, preferably, the plate body 324 and the rack 322 are preferably of an integral structure.

[0051] In some embodiments, the body 1 is provided with a containing groove containing the detection module 31, and a guide plate is further arranged in the containing groove to guide the detection module 31. The guide plate is used to guide the detection module 31, so that when the gear 321 drives the detection module 31 to move, the detection module 31 can only reciprocate in the horizontal direction, so as to further improve the movement accuracy of the detection module 31.

[0052] In some embodiments, the body 1 comprises a base 11, a middle plate 12 arranged on the base 11, and a top plate 13 arranged on the base 11 through the middle plate 12, and the motor 323 is arranged on the base 11, and the middle plate 12 is provided with an assembly hole through which the output shaft of the motor 323 passes.

[0053] The middle plate 12 and the top plate 13 can be fixed to the base 11 by screws.

[0054] In some embodiments, the containing groove is arranged on the top plate 13, and the containing groove is arranged on the side of the top plate 13 in contact with the middle plate 12, and the guide plate is an integral structure with the top plate 13.

[0055] In some embodiments, the positioning assembly 2 is arranged on the side of the top plate 13 away from the middle plate 12.

[0056] In some embodiments, the positioning assembly 2 can comprise a plurality of clamps with elastic deformation capability, and the plurality of clamps collectively position the PCB board.

[0057] The technical scheme of the utility model will be further introduced below in combination with specific application examples:

[0058] In the actual calibration process, first, the PCB board is placed on the positioning assembly 2, and the position of the PCB board is positioned by the positioning assembly 2, then the PCB board is powered, and at the same time, the PCB board is connected in communication with the detection system, the motor 323 is started, and the detection module 31 moves diagonally. Because the diagonal detection and correction pulls apart a certain distance, the interference of the two calibration processes will be extremely low, and because two different modules are calibrated at the same time, the speed can be improved. When the first diagonal detection is completed, the two modules move to the middle position for individual calibration of the middle position. After the middle detection is completed, the two modules move to the second diagonal for the last two detections. The original six calibration processes can be completed through four calibration processes, which saves time and avoids the difference problem, and improves the detection accuracy.

[0059] The above introduces the subject technical scheme of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation of the subject technical scheme of the utility model, and some details can be omitted in the specific implementation.

[0060] In addition, in some embodiments of the above utility model, a plurality of embodiments can be combined for implementation, and various combination schemes are not listed one by one due to the length of the article. Those skilled in the art can freely combine the above-mentioned embodiments according to the needs in specific implementation to obtain a better application experience.

[0061] Those skilled in the art can obtain other detailed configurations or drawings when implementing the subject technical solution of the utility model according to the subject technical solution of the utility model and the drawings. Obviously, these details still belong to the scope covered by the subject technical solution of the utility model without departing from the subject technical solution of the utility model.
