[0029] See also Figure 1 and Figure 2 The present invention shows a board and card detector, including a detector body 10, the detector body 10 is provided with a detection slot 11 for inserting a board and card 100, the board and card detector also includes a clamping and limiting mechanism 20, the clamping and limiting mechanism 20 includes an electric push rod 21, two connecting arms 22 and two limiting components 23, the two limiting components 23 are respectively arranged on the outer side wall of the detector body 10 and located on both sides of the length direction of the detection slot 11, each of the limiting components 23 includes a supporting block 231, a driving rod 232 and a limiting block 233, the electric push rod 21 is installed on the outer side wall of the detector body 10 and is located above the detection slot 11, the two connecting arms 22 are symmetrically arranged on both sides of the electric push rod 21, the first end of the connecting arm 22 is hinged to the electric push rod 21, and the second end of the connecting arm 22 is connected to the first end of the driving rod 232.

[0030] The support block 231 is fixedly connected to the outer wall of the detector body 10, and a sliding hole is provided on the support block 231. The driving rod 232 is passed through the sliding hole. The second end of the driving rod 232 is connected to the limit block 233. The electric push rod 21 is used to drive the connecting arm 22 to move so that the connecting arm 22 drives the driving rod 232 to move along the sliding hole, so that the limit block 233 clamps the board 100 or releases the board 100, so as to assist in fixing the board 10, improve the detection stability of the board 100, and improve the detection accuracy of the board 100.

[0031] In some embodiments, the outer wall of the detector body 10 is located on both sides of the length direction of the detection slot 11 and is respectively provided with an elastic component 30 at the lower position of the detection slot 11. The elastic component 30 includes a spring 31 and a baffle 32. The first axial end of the spring 31 is connected to the outer wall of the detector body 10, and the second axial end of the spring 31 is connected to the baffle 32. The baffle 32 is used to abut the bottom surface of the board and card 100. After the board and card 100 is detected, the clamping limit mechanism 20 releases the board and card 100. At this time, the baffle 32 will move outward under the action of the spring 31 to assist in pushing out the board and card 100, so that the board and card 100 is convenient for the staff to grasp and take out the detection slot 11. Of course, the elastic component 30 may not be provided.

[0032] Combination Figure 1 and Figure 3 In some embodiments, a pre-fixing component 40 is provided on the outer wall of the detector body 10 at the lower position of the detection slot 11 .

[0033] The pre-fixing assembly 40 includes a fixing rod 41, a fixing block 42 and a suction cup 43. The first axial end of the fixing rod 41 is connected to the outer side wall of the detector body 10, and the second axial end of the fixing rod 41 is connected to the fixing block 42 through the suction cup 43. The fixing block 42 can be arranged relative to the detection slot 11, so that when the board 100 is placed in the detection slot 11, the fixing block 42 can be limited by the outer side of the board 100 to prevent the board 100 from accidentally leaving the detection slot 11, thereby playing a role of pre-fixing and protection. Of course, when the size of the board 100 to be detected is moderate, the pre-fixing assembly 40 can be omitted, and no specific limitation is made here.

[0034] like Figure 3 As shown, in some embodiments, the suction cup 43 is provided with an air outlet, the fixing rod 41 is provided with a cavity 411, a slider 412 is provided in the cavity 411, the slider 412 is connected to a pull rope 413, one end of the pull rope 413 passes through the cavity 411, and the end of the pull rope 413 located outside the cavity 411 is provided with a hook 414, and the fixing rod 41 is provided with a hanging ring 415 for the hook 414 to be hung.

[0035] When in use, after inserting the board 100 into the detection slot 11, before the clamping and limiting mechanism 20 clamps and fixes the board 100, the fixing block 42 and the suction cup 43 can be fully fitted, and the suction cup 43 can generate a certain adsorption force on the fixing block 42 to pre-fix the board 100. At the same time, the hook 414 can be pulled so that the pull rope 413 drives the slider 412 to slide on the side wall of the cavity 411, and the gas between the fixing block 42 and the suction cup 43 can be adsorbed into the cavity 411 to increase the suction force of the suction cup 43, and then the hook 414 is hooked on the hanging ring 415. The slider 412 can increase the suction force of the suction cup 43, and reduce the suction cup 43 from easily falling off the side wall of the fixing block 42 when used for a long time.

[0036] like Figure 3 As shown, in some embodiments, the end of the hook 414 is provided with a fixing ball 416, and the side wall of the hanging ring 415 is provided with at least a pair of elastic sheets 417 for limiting the fixing ball 416. Preferably, the side wall of the hanging ring 415 is symmetrically fixed with a pair of elastic sheets 417. When in use, by hooking the hook 414 on the side wall of the hanging ring 415, the hook 414 can push the elastic sheet 417 open. When the fixing ball 416 passes through the elastic sheet 417, it can automatically reset under the elastic action of the elastic sheet 417, so that the elastic sheet 417 is against the side wall of the fixing ball 416. In this process, the elastic sheet 417 is against the fixing ball 416, which can play a role in preventing the hook 414 from falling off after hooking the hanging ring 415, improve the fixing effect of the hook 414 on the side wall of the hanging ring 415, and reduce the hook 414 from slipping off the side wall of the hanging ring 415 under the action of external force. Of course, in some embodiments, the fixing ball 416 and the elastic sheet 417 may not be provided, and this is not limited here.

[0037] like Figure 3As shown, in some embodiments, the inner cavity of the suction cup 43 is provided with a spring rod 431, one end of the spring rod 431 is connected to the end of the fixing rod 41, and the other end of the spring rod 431 is connected to a pair of elastic bands 432, which are symmetrically arranged on both sides of the spring rod 431 and have the same structure. One end of the elastic band 432 is connected to the inner side wall of the suction cup 43, and a first cleaning brush 433 is provided on the elastic band 432. When in use, when the fixed block 42 approaches the side wall of the suction cup 43, the fixed block 42 will first squeeze the spring rod 431. When the spring rod 431 shrinks into the suction cup 43, it will drive the elastic bands 432 on both sides to move into the suction cup 43. At this time, the first cleaning brush 433 will contact the side wall of the suction cup 43, and the first cleaning brush 433 will be used to clean the side wall of the suction cup 43. In this process, the dust and impurities attached to the side wall of the suction cup 43 are swept away by the first cleaning brush 433, which can increase the full fit between the suction cup 43 and the fixed block 42, improve the adsorption effect of the suction cup 43, and reduce some dust and impurities blocking between the suction cup 43 and the fixed block 42, thereby affecting the adsorption effect of the suction cup 43. Of course, in some embodiments, this structure may not be set, and its structure can be selected and set according to actual needs, which is not specifically limited here. In addition, in some embodiments, the fixed block 42 can also be connected by vacuum adsorption, and only preferred embodiments are given here, and are not specifically limited.

[0038] like Figure 4 As shown, in some embodiments, the upper and lower side walls of the detection slot 11 are further provided with an elastic mounting frame 50, and the elastic mounting frame 50 includes a plurality of elastic plates 51 connected to each other, and a plurality of second cleaning brushes 52 connected to the elastic plates 51. The elastic plates 51 may include a silicone plate or a rubber plate or other elastic plates.

[0039] When in use, when the board 100 is inserted into the detection slot 11, the board 100 will contact and squeeze the elastic plate 51, and the elastic plate 51 will not damage the board 100. At this time, the elasticity of the elastic plate 51 will exert a certain reaction force on the board 100, and the elastic plate 51 will slide toward the middle of the elastic plates 51 on both sides. When the board 100 slides into the detection slot 11, the second cleaning brush 52 can contact the side wall of the board 100, and the second cleaning brush 52 can be used to clean the side wall of the board 100. The wall is cleaned. In this process, the elastic plate 51 can play a limiting role when inserting the board 100 into the detection slot 11, improving the convenience of insertion. At the same time, the second cleaning brush 52 can clean the dust and impurities attached to the side wall of the board 100, reducing the dust and impurities from easily entering the detector body 10. After that, the elastic mounting frame 50 can be sucked away by a vacuum absorber. Of course, the impurities in the elastic mounting frame 50 are usually trace and will not affect the instrument. Of course, in some embodiments, the elastic mounting frame 50 may not be provided, and the staff can clean the outer side of the board 100 before the detection process.

[0040] In some embodiments, the elastic mounting frame 50 further includes an elastic rod 53 , the elastic rod 53 is connected to the elastic plate 51 , and rubber balls 54 are respectively disposed at both ends of the elastic rod 53 in the length direction.

[0041] like Figure 4 As shown, during use, when the board 100 is inserted into the detection slot 11, the board 100 will scratch the rubber ball 54. Under the action of the friction force generated by the contact between the two, the board 100 will drive the rubber ball 54 to move, causing the elastic rod 53 to produce a certain deformation. When the board 100 is pulled out of the detection slot 11 and the board 100 is separated from the rubber ball 54, the elasticity of the elastic rod 53 will drive the rubber ball 54 to swing, thereby generating a certain vibration effect. The vibration effect can be used to vibrate off the dust and impurities attached to the side wall of the second cleaning brush 52. In this process, the vibration effect generated by the swinging of the rubber ball 54 can play a role in cleaning the dust and impurities attached to the side wall of the second cleaning brush 52, thereby improving the subsequent cleaning effect of the second cleaning brush 52 and reducing the second cleaning brush 52 from being inconvenient to clean the dust and impurities attached to its side wall due to long-term use, thereby affecting the use effect of the second cleaning brush 52. Of course, in some embodiments, the elastic rod 53 and the rubber ball 54 may not be provided, and the staff may clean the outer side of the board 100 before the inspection process.

[0042] like Figure 4As shown, in some embodiments, the outer side wall of the detector body 10 is located at the upper and lower sides of the detection slot 11 and is provided with a slide rail 60, the slide slot of the slide rail 60 is slidably connected with a guide block 61, an elastic pad 62 is provided between the guide block 61 and the slide slot of the slide rail 60, and the guide block 61 is connected to the elastic mounting bracket 50 through a connecting plate 63. The connecting plate 63 can be roughly L-shaped.

[0043] Combination Figure 1 and Figure 5 As shown, in some embodiments, the board card detector further includes a carrier plate 70, the lower end of which is connected to the outer side wall of the detector body 10, and the upper end of which is fixed to the outer side wall of the detector body 10 by magnetic attraction. For example, the outer side wall of the detector body 10 may be provided with a first magnet 12, the lower end of the carrier plate 70 may be connected to the outer side wall of the detector body 10 by rotation through a rotating shaft seat, etc., and the upper end of the carrier plate 70 is provided with a second magnet 71 to be magnetically fixed to the first magnet 12. When it is necessary to temporarily store the board card 100, the carrier plate 70 may be opened and the board card 100 may be placed on the carrier plate 70. Of course, a storage frame or a storage basket may also be provided on the detector body 10, which is not specifically limited here.

[0044] In some embodiments, the board tester may further include a computer / industrial computer 80 connected to the tester body 10 .
