DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1-2 The utility model provides a technical solution: a circuit board tester, including an operating table 1 and a placement plate 3, a tester 2 is fixedly connected to the surface of the operating table 1, an operation panel 4 is fixedly connected to the surface of the operating table 1, an auxiliary device 5 is provided on the surface of the operating table 1, and an anti-mistouch device 6 is provided on the surface of the operating table 1.
[0033] The specific configuration and functions of the auxiliary device 5 and the anti-mistaken-touch device 6 are described in detail below.
[0034] like Figure 2 - Figure 5As shown, the auxiliary device 5 includes two sliding frames 501, the two sliding frames 501 are fixedly connected to the surface of the operating table 1, the surfaces of the two sliding frames 501 are slidably connected with a moving frame 502, the surface of the moving frame 502 is fixedly connected with two magnets 504, the surfaces of the two sliding frames 501 are fixedly connected with iron sheets 505, the moving frame 502 is fixedly connected to the placement plate 3, the surface of the moving frame 502 is fixedly connected with a baffle 503, both sides of the moving frame 502 are fixedly connected with two connecting plates 506, the two connecting plates 506 are rotatably connected to the sides close to each other with a bidirectional screw rod 507, the surface of the bidirectional screw rod 507 is fixedly connected with a rotating rod 512, the surface of the bidirectional screw rod 507 is threadedly connected with two limiting frames 510, and the two limiting frames 510 are slidably connected to the connecting plates 506, which can assist the circuit board to be quickly placed in position, and the staff does not need to use the naked eye to observe and adjust, which facilitates the alignment work. At the same time, when the test work is performed, the circuit board will not move due to the movement of the operating table 1, which further facilitates the test work. The inner wall of the limit frame 510 is glued with a protective pad 511, and the protective pad 511 is made of sponge. Since the protective pad 511 is made of sponge, it will not be damaged when the circuit board is clamped, which facilitates the limit clamping work. The surface of the two-way screw 507 is fixedly connected with a gear 508, and the surface of the gear 508 is meshed with an internal toothed belt 509. When the two-way screw 507 rotates, it can drive the gear 508 to rotate, and then through the internal toothed belt 509, it can drive the two two-way screws 507 to rotate at the same time. Further, the two limit frames 510 on the surface of the two-way screw 507 can move in a direction close to each other, thereby achieving the clamping work of the circuit board, facilitating the operation and use of the auxiliary device 5, and increasing the convenience of the auxiliary device 5. A plurality of anti-skid grooves 513 are provided on the surface of the rotating rod 512 . The plurality of anti-skid grooves 513 are linearly arrayed on the arc surface of the rotating rod 512 . The anti-skid grooves 513 can increase the friction between the fingers of the staff, thereby facilitating the staff to rotate the rotating rod 512 .
[0035] like Figure 1 and Figure 6 as well as Figure 7As shown, the anti-mis-touch device 6 includes two connecting rods 61, and the surfaces of the two connecting rods 61 are slidably connected with a pressure plate 62. The surfaces of the two connecting rods 61 are sleeved with springs 63, and the two ends of the spring 63 are respectively fixedly connected to the connecting rods 61 and the pressure plates 62. The surface of the tester 2 is fixedly connected with a low-voltage rod 68, and the surface of the pressure plate 62 is rotatably connected with two rotating shafts 65. The surfaces of the two rotating shafts 65 are fixedly connected with cover plates 67. When the circuit board is tested, the buttons on the operation panel 4 can be prevented from being accidentally touched, so that the circuit board can complete the test work well, thereby improving the stability of the test, ensuring the accuracy of the test data, and improving the test effect of the circuit board. The surfaces of the two rotating shafts 65 are sleeved with two torsion springs 66, and the two ends of the two torsion springs 66 are fixedly connected to the cover plate 67 and the pressure plate 62 respectively. When the button needs to be pressed, the staff can rotate the cover plate 67 to complete the pressing of the button. After the pressing is completed, the staff releases the cover plate 67, and the cover plate 67 can be automatically reset by the torsion spring 66, further increasing the anti-mistouch effect of the cover plate 67. The surface of the operation panel 4 is slidably connected with two blocking rings 64. Due to the addition of the blocking rings 64, the cover plate 67 will not press the test button and the stop button when it rotates and moves downward, further facilitating the use of the anti-mistouch device 6.
[0036] Working principle: When conducting circuit board testing, the staff can pull the movable frame 502 outward to disengage the magnet 504 from the adsorption relationship with the iron sheet 505, and then slide the movable frame 502 outward, and further the staff can place the circuit board on the surface of the placement table, and can press and align one end of the circuit board with the surface of the baffle 503, and further the staff can use the rotating rod 512 to rotate the bidirectional screw rod 507, and the anti-skid groove 513 on the surface of the rotating rod 512 can increase the friction between the fingers of the staff, thereby facilitating the staff to rotate the rotating rod 512, and when the bidirectional screw rod 507 rotates, it can drive the gear 508 to rotate, and then through the internal toothed belt 509, it can simultaneously drive the two bidirectional screw rods 507 to rotate, and further the two limit frames 510 on the surface of the bidirectional screw rod 507 can move in a direction close to each other, thereby achieving the circuit board. For the clamping work, there is a protective pad 511 on the side of the limit frame 510 close to the circuit board. Since the protective pad 511 is made of sponge material, no damage will occur when the circuit board is limited and clamped, which facilitates the limit clamping work. At this time, the limit work of the circuit board is completed, and the staff does not need to use the naked eye to observe and align, which facilitates the circuit board detection work. Then the staff slides the movable frame 502 in the direction of the tester 2, which can make the magnet 504 and the iron sheet 505 adsorbed together, and then the movable frame 502 is limited. At this time, the tester 2 can be used to detect the circuit board. By setting the auxiliary device 5, the circuit board can be assisted to be quickly placed in position, and the staff does not need to use the naked eye to observe and adjust, which facilitates the alignment work. At the same time, when performing the test work, the circuit board will not move due to the movement of the operating table 1, which further facilitates the test work.
[0037] When testing the circuit board, the staff will press the operating table 1, which can further drive the low-voltage rod 68 to press against the surface of the pressure plate 62, drive the pressure plate 62 to slide downward, and then drive the cover plate 67 to slide downward, so as to cover the test button and the stop button on the surface of the operation panel 4, so that when the circuit board is tested, there will be no accidental touch. The test button and the stop button are provided with a blocking ring 64. Due to the addition of the blocking ring 64, the cover plate 67 will not press the test button and the stop button when it is rotated and moved downward, which further facilitates the use of the anti-accidental touch device 6. When the button needs to be pressed, the staff can rotate the cover plate 67 to complete the pressing of the button. After completing the pressing, the staff releases the cover plate 67, and the cover plate 67 can be automatically reset by the torsion spring 66, further increasing the anti-mistouch effect of the cover plate 67. When the test is completed, the operator will move upward, and the pressing rod will be separated from the pressure on the pressing plate 62. At this time, the pressing plate 62 can be reset by the spring 63, which will not affect the staff's subsequent operation of the operation panel 4. By setting the anti-mistouch device 6, the buttons on the operation panel 4 can be prevented from being accidentally touched when the circuit board is tested, so that the circuit board can complete the test work well, thereby improving the stability of the test, ensuring the accuracy of the test data, and improving the test effect of the circuit board.
