DETAILED DESCRIPTION

[0021] The following specific embodiments illustrate the embodiments of the present application, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosed content. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] In combination with reference to Figures 1-4 The present application provides a kind of integrated circuit board line resistance test fixture, including test table 1, test table 1 is fixedly connected with support 2.

[0023] In the embodiment: the side surface of support 2 is fixedly connected with servo motor 3, and the output end of servo motor 3 passes through support 2 and is fixedly connected with circuit board test angle seat 4.

[0024] Circuit board test angle seat 4 preferably adopts hexagonal seat shape, when the top of circuit board test angle seat 4 is in horizontal state, then the inclined surface of one side of the top of circuit board test angle seat 4 can conveniently support integrated circuit board pre-feeding, and servo motor 3 can drive circuit board test angle seat 4 to intermittently rotate with sixty degrees as a period.

[0025] In the embodiment: the outer surface of circuit board test angle seat 4 is fixedly connected with rubber pad 5, and the number of rubber pad 5 is multiple.

[0026] The number of rubber pad 5 can be set along with the number of angles of circuit board test angle seat 4, and rubber pad 5 can provide flexible support for integrated circuit board, which can avoid the problem of damage caused by pressure during integrated circuit board resistance test.

[0027] Rubber positioning column 6 fitted with integrated circuit board mounting hole plug-in is detachably connected on rubber pad 5, and one end of rubber positioning column 6 is provided in the form of a sharp end.

[0028] The setting of sharp end of rubber positioning column 6 can facilitate the entry of integrated circuit board mounting hole, and two pairs of rubber positioning columns 6 need to be provided on each rubber pad 5. Since rubber positioning column 6 is made of rubber material, and the size of rubber positioning column 6 is relatively smaller than the size of mounting hole, so that integrated circuit board inserted on rubber positioning column 6 through mounting hole can realize the effect of elastic plug-in, i.e. the elastic tensioning plug-in effect of rubber positioning column 6 to mounting hole, which can reduce the freedom of integrated circuit board positioning.

[0029] In this embodiment: the outer surface of the rubber pad 5 is threaded with two pairs of threaded heads 11, and the outer surface of the rubber pad 5 is provided with several threaded grooves for threaded connection of the threaded heads 11. The rubber positioning post 6 is fixedly connected to the outside of the threaded head 11.

[0030] The threaded head 11 can support and fix the position of the rubber positioning post 6. Since the threaded head 11 can be flexibly assembled on the threaded groove, when testing a batch of integrated circuit boards with different mounting hole spacing than the previous batch, the position of the rubber positioning post 6 can be adjusted to use the mounting hole position.

[0031] In this embodiment: an electric push rod 7 is fixedly connected to the top of the bracket 2, a test board 8 is provided on the electric push rod 7, and test pins 9 for testing the resistance of the integrated circuit board are provided at the bottom of the test board 8.

[0032] Once the integrated circuit board is positioned on one of the rubber pads 5 by the rubber positioning post 6, the servo motor 3 can drive the circuit board test corner bracket 4 to a specified angle so that the integrated circuit board is located below the test board 8. In this way, the electric push rod 7 can drive the test pins 9 on the test board 8 to press down on the test points of the integrated circuit board. During this process, the user can put the integrated circuit board to be tested on another rubber pad 5 on the same side of the aforementioned rubber pad 5.

[0033] It is worth noting that the settings of test board 8 and test pin 9 are matched with the resistance test of integrated circuit board. When the rubber positioning post 6 is adjusted, test board 8 and test pin 9 also need to be replaced.

[0034] In this embodiment: a resistance tester 12 is provided on the test bench 1, and the resistance tester 12 is electrically connected to the test pin 9 through the corresponding test leads.

[0035] After the test pin 9 contacts the test point on the integrated circuit board, the resistance tester 12 can test the resistance value of the integrated circuit board and display the data through the test pin 9. Since the resistance tester 12 is a general standard part or a component known to those skilled in the art, its structure and principle are known to the technical personnel through technical manuals or conventional experimental methods, so the resistance tester 12 will not be described in detail here.

[0036] In this embodiment: the output end of the electric push rod 7 passes through the bracket 2 and is fixedly connected to the lifting plate 13. The top of the lifting plate 13 is fixedly connected to the spring telescopic rod 14. The test plate 8 is fixedly connected to one end of the spring telescopic rod 14. The test plate 8 is located above the circuit board test corner seat 4.

[0037] The spring telescopic rod 14 consists of a telescopic rod and a spring sleeved on the outside of the telescopic rod. When the electric push rod 7 pushes the test board 8 down through the lifting plate 13, the rubber pad 5 can provide the first stage of buffer protection for the integrated circuit board test, and the spring telescopic rod 14 can further provide buffer protection for the integrated circuit board test by contracting and deforming, thus improving the safety of the integrated circuit board test.

[0038] In this embodiment: the electric push rod 7 is also provided with a top feeding assembly 10. The top feeding assembly 10 is used to control the feeding of the integrated circuit board inserted on the rubber positioning post 6. The side of the circuit board test corner seat 4 is provided with an inner groove. The top feeding assembly 10 includes a lifting frame 101. One end of the lifting frame 101 is fixedly connected to the lifting plate 13. The other end of the lifting frame 101 extends into the inner groove and is fixedly connected to a top post 102. The circuit board test corner seat 4 and the rubber pad 5 are both provided with top grooves for the top post 102 to pass through. The top post 102 is movably connected to the integrated circuit board inserted on the rubber positioning post 6.

[0039] In this application, the total number of top slots is twice the number of rubber pads 5. The end of the top post 102 that contacts the integrated circuit board can be a rubber head. When the test pin 9 descends to perform resistance testing on the integrated circuit board located on the rubber pad 5 directly above, the lifting plate 13 can drive the top post 102 through the top slots opened on the circuit board test corner 4 and the rubber pad 5 via the lifting frame 101. Whenever the tested integrated circuit board is transferred to the bottom via the circuit board test corner 4, the integrated circuit board that is elastically inserted on the rubber pad 5 directly below can be pushed out downward by the top post 102 to achieve the effect of automatic unloading of the integrated circuit board. The unloading position of the integrated circuit board can be achieved by placing a collecting device on the test table 1 to receive the integrated circuit board.

[0040] It is worth noting that, in order to facilitate the control of the operation of the servo motor 3 and the electric push rod 7, a push button switch for independently controlling the servo motor 3 and the electric push rod 7 can be installed on the bracket 2. The push button switch can be connected to the servo motor 3 or the electric push rod 7 using conventional wiring methods, and the power supply is also common knowledge in this field.
