[0002] When the PCBA board to be tested is undergoing functional testing, the PCBA board to be tested is usually placed on a fixture, and then the fixture is sent to the test machine. The interface on the fixture is connected to the connector on the test machine to achieve power-on and signal connection, and then the PCBA board to be tested is tested. Each test machine can be equipped with multiple corresponding fixtures according to different PCBA boards to be tested, which can be replaced accordingly when testing different products.

[0003] Usually, the connection between the fixture and the test machine is often made through a wiring harness connector. There are many different modules on the connection port of a test machine, and the fixture needs to be manually connected one by one with the wiring harness, which is inefficient. In addition, the current form of docking between the fixture and the test machine mainly relies on the operator to manually push the fixture into the test machine, and then manually pull the fixture out of the test machine after the test is completed. Due to the poor control of manual strength, the resistance between the fixture and the test machine is too large during the plug-in process, and a lot of effort is required to complete the docking, and the docking accuracy cannot be guaranteed. Long-term operation will affect the life of the PIN pins in the fixture plug-in end carrying the PCBA board. It is necessary to provide a pushing device suitable for the test machine and convenient for docking between the PCBA board and the test machine, so as to facilitate the conduction test between the test machine and the PCBA board, improve the detection efficiency of the PCBA board, and reduce the detection error.

[0045] In order to solve the defects of the prior art, the present invention provides a push docking device for circuit board detection, see Figures 1 to 5 As shown, Figure 1 The overall structural schematic diagram of the push docking device provided by the present invention is shown.

Figure 5 Show Figure 1 Schematic diagram of the matching between the mounting plate of the middle mounting seat and the connector.

[0046] In conjunction with the above drawings, specifically, the docking device provided by the present invention includes:

[0047] Bottom plate 1;

[0048] Connector assembly; and

[0049] Push component;

[0050] The connector assembly comprises:

[0051] A mounting base 2 fixed on the bottom plate 1 and a connector 3 with a plug end exposed on the mounting base 2;

[0052] The push component includes:

[0053] A rotating shaft 4 located on the bottom plate 1 and rotatable around its own axis;

[0054] A push-pull member 5 connected to the rotating shaft 4 is located on the surface of the bottom plate 1; the push-pull member 5 includes a main body 51, and the head end of the main body 51 of the push-pull member 5 includes a card slot 52, and the card slot 52 extends to the outside of the front end of the plug end of the connector 3;

[0055] The push-pull member 5 is configured to slide along a straight line on the surface of the bottom plate 1 through the rotation of the rotating shaft 4;

[0056] The axis direction of the rotating shaft 4 is arranged orthogonally to the sliding direction of the push-pull member 5;

[0057] The plugging direction of the plugging end of the connector 3 is the same as the sliding direction of the push-pull member 5 .

[0058] The present invention can drive two symmetrically arranged push-pull members 5 to make horizontal linear motion on the plate surface of the bottom plate 1 through the semicircular motion of the rotating shaft 4. The fixture connected and fixed to the push-pull member 5 can be easily moved along the sliding direction of the push-pull member 5 through the card slot 52 at the head end of the push-pull member 5, that is, the push-pull member 5 is used to pull or push out the fixture carrying the PCBA board, thereby realizing the conduction test between the PCBA board and the test machine, and there is no need for the operator to manually connect or dock the fixture plug-in end carrying the PCBA board with the test machine connector plug-in end, which facilitates the conduction test between the PCBA board and the test machine, simplifies the operation process, and improves work efficiency; and the device eliminates the wiring harness connector used for connecting between the existing fixture plug-in end and the test machine connector plug-in end, saving production costs. Those skilled in the art can understand that, in one embodiment, before the fixture is connected to the test machine through the docking device provided by the present invention, the electrical connector on the PCBA board itself is first connected to the plug-in connection between the fixture. In this case, the docking device provided by the present invention serves as a connecting device between the fixture and the test machine to achieve conduction between the PCBA board and the test machine.

[0059] In another embodiment, the PCBA board can be first fixed on the jig, and the docking device provided by the present invention utilizes a push-pull member to drive the jig carrying the PCBA board to perform horizontal linear motion on the board surface of the base plate. In this case, the electrical connector on the PCBA board itself can be plugged in corresponding to the plug-in end of the connector assembly connector. The present invention does not limit the configuration and plug-in matching method in the above embodiment.

[0060] In addition, by using the docking device provided by the present invention, the docking and plugging force and plugging stroke between the fixture and the test machine are fully controllable and are not affected by the different forces of the operator manually pushing in or pulling out the fixture. The docking consistency and reliability between the fixture and the test machine can be effectively guaranteed, thereby improving the connection quality between the fixture and the test machine, protecting the docking probe at the connector plug-in end and the probe at the fixture plug-in end, objectively improving the detection efficiency, and reducing the detection error of the PCBA board.

[0061] Combined with Figure 1 , Figure 5 As shown, the connector assembly and the push assembly are both arranged on the upper surface of the base plate 1, wherein the mounting seat 2 is combined and fixed on the upper surface of the base plate 1, and the push-pull member 5 is also located on the upper surface of the base plate 1. The end of the push-pull member 5 away from the rotating shaft is the head end of the push-pull member 5, and the end close to the rotating shaft 4 is the tail end of the push-pull member 5. The opening direction of the card slot 52 is toward the direction away from the upper surface of the base plate 1, so as to facilitate connection with the fixture carrying the PCBA board. More specifically, in one embodiment, the mounting seat 2 includes a cover body 21 with a front opening and a mounting plate 22 located at the opening of the cover body 21. The connector 3 is mounted on the front outer side of the mounting plate 22. Since there are many connectors plugged in between the fixture carrying the PCBA board during the detection process, preferably, connectors of different types, functions and plug-in methods can be configured and pre-assembled on a mounting sub-board 23, and then various types of connectors can be installed on the front outer side of the mounting plate 22 through the mounting sub-board 23, so as to facilitate the selection of different connectors according to actual needs and facilitate the selection and installation of connectors. Different connectors can be fixed side by side on the mounting sub-board 23, and the connectors may include a high current PIN needle module, a low current PIN needle module, a signal PIN needle module, a pneumatic connection module, etc.; high current PIN needles, low current PIN needles, signal PIN needles, and pneumatic joints are installed on the corresponding modules. These connectors can be positioned and connected with the mounting sub-board through positioning pins to achieve rapid replacement to adapt to different types of test functions.

[0062] In one embodiment, the cover 21 and the mounting plate 22 form a cavity, and most of the components of the push assembly can be accommodated in the cavity. Figure 1As shown, the rear end of the push-pull member 5 is located in the cavity, and the head end extends from the cavity and is located outside the front end of the mounting plate 22, so that the card slot 52 at the head end of the push-pull member 5 is connected to the fixture carrying the PCBA board.

[0063] Combined with the structure shown in the figure, in order to ensure the rotation of the rotating shaft 4, the two symmetrically arranged push-pull members 5 can be smoothly driven to perform horizontal linear motion on the board surface of the bottom plate 1. The bottom plate 1 includes a limiter 6 fixedly combined with the board body of the bottom plate 1. A limiter cavity is formed between the limiter 6 and the upper board surface of the board body of the bottom plate 1, and the push-pull member 5 is inserted into the limiter cavity 6. It should be noted that in the embodiment shown in the present invention, the limiter 6 is used to limit the push-pull member 5 to slide along a straight line. In other embodiments, a guide rail structure in which the matching part between the push-pull member and the bottom plate body is a dovetail groove can also be used to limit the push-pull member from being lifted off the bottom plate surface. Regardless of the limit structure, its function is that under the driving force of the rotation of the rotating shaft, the push-pull member can only slide linearly along the limited push direction on the upper board surface of the bottom plate, so as to avoid deviation between the fixture plug-in end carrying the PCBA board and the connector plug-in end during the docking process, resulting in damage to the fixture plug-in end or the connector plug-in end.

[0064] In one embodiment, the pushing assembly includes a rotating block 41 combined and fixed on the rotating shaft 4, and a pulling shaft block 42 located between the rotating block 41 and the push-pull member 5; the two ends of the pulling shaft block 42 are respectively hinged and fixed to the rotating block 41 and the rear end of the push-pull member 5. Specifically, bearing seats 43 are respectively installed at both ends of the rotating shaft 4; the bearing seats 43 are respectively fixed on support blocks 44, and the support blocks 44 are fixed on the bottom plate 1; the two ends of the rotating shaft 4 are tightly fitted with the two bearing seats 43, and the bearing seats 43 play a role of fixing and rotating. It should be noted that the bearing seat and the support block can be an integral component, or they can be arranged as two combined and fixed components to adapt to the height of the rotating shaft on the bottom plate, and there is no limitation on this. The rotating shaft 4 is processed with key grooves at the positions near the two ends, and matching keys are installed in the key grooves. The rotating block 41 is fixedly sleeved on the rotating shaft 4 and fixed by keys to prevent relative rotation between the rotating block 41 and the rotating shaft 4. The rotating block 41 can rotate with the rotating shaft 4. The end of the rotating block 41 is processed with an axle pin hole, and an axle pin is installed in the pin hole of the rotating block 41; and the pulling shaft block 42 is sleeved on the axle pin; both ends of the pulling shaft block 42 have axle pin holes, and the axle pin hole at one end is aligned with the axle pin hole of the rotating block 41, and they are connected by the axle pin, and the axle pin can be clamped with a retaining spring to prevent the rotating block 41 and the pulling shaft block 42 from being separated due to the axle pin falling off, and the axle pin hole at the other end of the pulling shaft block 42 is aligned with the axle pin hole at the tail end of the push-pull member 5, and they are also connected by the axle pin.

[0065] In one embodiment, the push assembly further includes a handle portion 7 connected and fixed to one end of the rotating shaft 4. When the handle portion 7 is pressed down and rotated, the head end of the push-pull member 5 moves in a direction close to the connector 3; when the handle portion 7 is lifted and rotated, the head end of the push-pull member 5 moves in a direction away from the connector 3. Specifically, the handle portion 7 includes a handle body 71 and a rotating ball 72. One end of the handle body 71 is processed into a screw structure, and the other end is processed into a threaded hole. There is a screw on the rotating ball 72, which is fixed in the threaded hole at one end of the handle body 71 through the screw. The other end of the handle body 71 is a screw, and a coupling block 73 can be installed. During operation, the rotating ball 72 on the handle body 71 is held to drive the handle portion 7 to rotate up and down. The coupling block 73 and the rotating shaft 4 are tightly fitted through a cavity, and a tightening screw can be added to lock the coupling block 73 and the rotating shaft 4.

[0066] In this embodiment, when the handle portion 7 is pressed down and rotated, the head end of the push-pull member 5 moves in the direction close to the connector 3; when the handle portion 7 is lifted and rotated, the head end of the push-pull member 5 moves in the direction away from the connector 3. The advantage is that it makes the docking process of the jig plug-in end carrying the PCBA board and the connector 3 more labor-saving, and when the jig plug-in end carrying the PCBA board and the connector 3 are connected, the handle portion 7 is in a pressed-down state, will not interfere with other structures of the test machine, and can also prevent personnel from operating incorrectly.

[0067] Combination Figures 2 to 4 As shown, in this embodiment, the push-pull member 5 also includes a boss portion 53 formed at the rear end position of the main body portion 51 of the push-pull member 5, and the boss portion 53 includes a mating surface corresponding to the rear end face 61 of the limiter 6 facing the rear end of the push-pull member; in this embodiment, a magnet 8 is arranged on the rear end face 61 of the limiter 6, and when the handle portion 7 is lifted and rotated, the head end of the push-pull member 5 moves in a direction away from the connector 3, and when the push-pull member 5 is in the push-out position, the boss portion 53 is close to the limiter 6, and the magnet 8 is arranged on the rear end face 61 of the limiter 6, and the magnet 8 can adsorb and fix the rear end boss portion 53 of the push-pull member 5 on the limiter 6, limit the position of the push-pull member 5 in the push-out position, and prevent the handle portion 7 from automatically falling from the high position. It can be understood that the material of the push-pull member should be a metal material that can be adsorbed and fixed by a magnet.

[0068] In other embodiments, the magnet can also be arranged on the mating surface of the boss portion of the push-pull member. When the handle portion is lifted and rotated, the head end of the push-pull member moves away from the connector. When the push-pull member is in the push-out position, the boss portion is close to the limiter. By using the magnet arranged on the mating surface of the boss portion, the magnet can adsorb and fix the boss portion at the rear end of the push-pull member on the limiter, thereby limiting the position of the push-pull member in the push-out position. As mentioned above, in this case, the material of the limiter should also be a metal material that can be adsorbed and fixed by the magnet.

[0069] Or in another embodiment, the mating surface of the boss and the rear end surface of the limiter respectively include mutually matching magnets with different polarities. By using the mutually matching magnets with different polarities respectively included on the mating surface of the boss and the rear end surface of the limiter, the boss at the rear end of the push-pull member and the limiter can be adsorbed and fixed together.

[0070] See also Figure 1 as well as Figure 2 As shown, in one embodiment, the push-pull member 5 further includes an extension portion 54 located at the head end of the main body portion 51 of the push-pull member 5 and extending in the direction away from the body of the bottom plate 1, and the extension portion 54 is located on the side of the card slot 52 close to the connector assembly; the extension portion 54 includes a portion corresponding to the front end surface of the side of the base 1 where the connector 3 is configured. It can be understood that in the moving direction of the push-pull member 5, the length of the extension portion 54 should meet the maximum stroke of the jig plug end carrying the PCBA board and the connector 3 during the docking process, so as to avoid the jig plug end carrying the PCBA board and the connector 3 plug end being affected by the push-pull member extension and affecting the detection.

[0071] By utilizing the setting of the portion of the extension portion 54 corresponding to the front end surface of the base 1 on one side equipped with the connector 3, the movement of the head end of the push-pull member 5 toward the connector 3 can be limited, thereby preventing the plug-in overload of the jig plug-in end carrying the PCBA board and the connector 3 plug-in end during the docking process, that is, preventing the travel of the head end of the push-pull member 5 toward the connector 3 from exceeding the travel of the jig plug-in end carrying the PCBA board and the connector 3 plug-in end, thereby effectively protecting the docking probe of the connector 3 plug-in end and the probe of the jig plug-in end carrying the PCBA board, thereby preventing the plug-in probes of the two from being damaged or even destroyed.

[0072] In the embodiment provided by the present invention, Figure 5 In the structure shown, the mounting seat 2 includes a guide groove 24 for the push-pull member 5 to pass through. The guide groove 24 is located on the mounting plate 22 of the mounting seat 2. On the one hand, it limits the position between the mounting seat 2 and the push-pull member 5, and on the other hand, it can ensure that the push-pull member 5 can be plugged in the same axial direction relative to the plug-in end of the connector 3 located on the mounting seat 2, and there is no skewed plug-in and docking between the plug-in end docking probe of the connector 3 and the plug-in end probe of the jig carrying the PCBA board.

[0073] When the limiter 6 provided in the embodiment of the present invention is used to limit the push-pull member 5, in order to reduce the resistance of the push-pull member 5 to slide in a straight line on the surface of the bottom plate 1, the friction between the bottom surface of the push-pull member 5 and the upper surface of the bottom plate 1 is reduced, so that the rotation of the shaft 4 drives the push-pull member to slide, and the driving force used to drive the rotation of the shaft is reduced. In a preferred embodiment, combined with Figures 2 to 4As shown, a slide plate 9 is provided between the limit member 6 and the upper surface of the bottom plate 1 , and the surface of the slide plate 9 facing away from the bottom plate 1 includes a smooth surface corresponding to the bottom surface of the push-pull member 5 , and the bottom surface of the push-pull member 5 is located on the smooth surface.

[0074] It should be noted that, since the side walls and the top wall in the inner wall of the limiting cavity are only affected by the friction of the pushing and pulling member sliding in a straight line relative to the corresponding outer walls of the pushing and pulling member body, and are not subjected to additional pressure in the relative direction, preferably, the inner wall of the limiting cavity defined by the limiting member can also be set to a smooth surface relative to the outer wall of the pushing and pulling member body that can reduce the relative sliding friction between the two, or vice versa, the outer wall of the pushing and pulling member body can be set to a smooth surface relative to the inner wall of the limiting cavity defined by the limiting member that can reduce the relative sliding friction between the two. The present invention does not impose further restrictions on this.

[0075] In a specific embodiment of the present invention, Figure 5 As shown, the connector assembly further includes a guide shaft 25 located on the mounting seat 2, and the extension direction of the guide shaft 25 is the same as the plug-in direction of the plug-in end of the connector 3. The advantage is that it is convenient to position the plug-in end of the jig carrying the PCBA board when it is docked with the plug-in end of the connector 3.

[0076] In addition, in the docking device provided by the present invention, the upper surface of the base plate 1 also includes a bearing surface 11 located outside the front end of the connector assembly; the bearing surface 11 includes a slide 12 extending along the plug-in direction of the plug-in end of the connector 3. The slide 12 can be fixed to the upper surface of the base plate 1 by a countersunk screw. The bearing surface 11 is used to carry and place a jig carrying a PCBA board, and two slides 12 are symmetrically arranged to reduce the sliding resistance of the jig on the bearing surface 11. It can be understood that the end of the jig carrying the PCBA board close to the connector assembly includes a connecting portion that is connected to the push-pull member slot.

[0077] The push-and-dock device provided in the present invention further includes an assembly plate 13 located on the bottom plate, and the assembly plate 13 is configured to assemble the push-and-dock device to the testing machine.

[0078] Combination Figure 1 As shown, in the embodiment provided by the present invention, the assembly plate 13 is located at the rear end of the base plate 1. It can be understood that based on the different structures of various test machines, the test machine and the push-to-docking device provided by the present invention have different assembly structures, assembly surfaces and assembly forms. The present invention provides an assembly plate structure included in the push-to-docking device, the position of the assembly plate relative to the base plate, and the connection structure on the test machine that is fixedly docked with the assembly plate, as well as the position of the push-to-docking device provided by the present invention on the test machine. The present invention does not limit this.

[0079] During the actual operation, the test fixture is first placed on the slide 12 of the bearing surface 11 of the base plate 1, and the connecting part of the fixture for cooperating with the slot 52 of the push-pull member 5 is fixed to the slot 52 of the push-pull member 5.
