[0002] Electronic components usually need to be tested before leaving the factory, such as the mainboards of mobile phones, tablets and computers.

[0049] In the test device of the first aspect of the application, it is applied to detect the circuit board, and the test device comprises Figures 1-2 , Figure 1 Figure 2 is a schematic view of the card joint of the first aspect of the application moving the second detection member to the first connecting member, Figure 2 Figure 2 is a schematic view of the card joint of the first aspect of the application moving the second detection member to the first connecting member, The test device of the first aspect of the application comprises a moving front end 200, a first detection member 300, a second detection member 400, a switching assembly 500 and a driving assembly. The moving front end 200 is provided with a first connecting member 210. The first detection member 300 is slidably connected to the moving front end 200 in a first direction to approach or move away from the circuit board. The side of the first detection member 300 protrudes and is provided with a second connecting member 310. The first connecting member 210 and the second connecting member 310 are spaced apart in the first direction. The second detection member 400 is slidably connected to the moving front end 200 in the first direction to approach or move away from the circuit board. The second detection member 400 is located on the side of the first detection member 300 and faces the second connecting member 310. The switching assembly 500 comprises a card joint 510 and a first driving member 520. The first driving member 520 is connected to the card joint 510 and is used to drive the card joint 510 to move the second detection member 400 in the first direction, so that the second detection member 400 is separated from the first detection member 300 and connected to the first connecting member 210, and the detection end of the first detection member 300 protrudes relative to the detection end of the second detection member 400, or the second detection member 400 is separated from the first connecting member 210 and connected to the second connecting member 310, and the detection end of the second detection member 400 protrudes relative to the detection end of the first detection member 300. The driving assembly is installed on the moving front end 200. The driving assembly comprises a second driving member 600. The second driving member 600 is connected to the first detection member 300 and is used to drive the first detection member 300 separated from the second detection member 400 to move in the first direction, or drive the first detection member 300 and the second detection member 400 connected to each other to move synchronously in the first direction.

[0050] Specifically, when the first detection member 300 needs to be used for detection, the clamping member 510 is clamped to the second detection member 400, the first driving member 520 drives the clamping member 510 to move in the first direction, so as to separate the first detection member 300 and the second detection member 400 connected with each other, and make the second detection member 400 move towards the first connecting member 210 and finally connect to the first connecting member 210, so that the second driving member 600 drives the first detection member 300 to move in the first direction alone, and realizes the detection work of the first detection member 300; when the second detection member 400 needs to be used for detection, the clamping member 510 is clamped to the second detection member 400, the first driving member 520 drives the clamping member 510 to move in the first direction, so as to make the second detection member 400 connected to the first connecting member 210 to be moved to connect the second connecting member 310 on the first detection member 300, then the clamping member 510 and the second detection member 400 are separated, and then the second driving member 600 drives the first detection member 300 to move in the first direction, and the first detection member 300 drives the second detection member 400 to move synchronously, because the detection end of the second detection member 400 is protruded than the detection end of the first detection member 300, therefore, when the two move synchronously, the detection end on the second detection member 400 can contact the circuit board first, so as to realize the detection work of the second detection member 400. In summary, when the first detection member 300 is used for detection, the second detection member 400 is moved to connect with the first connecting member 210; when the second detection member 400 is used for detection, the second detection member 400 and the first detection member 300 are connected, so that the first detection member 300 drives the second detection member 400 to move synchronously.

[0051] It should be noted that the weight increase of the driving member installed on the movement front end 200 will affect the limit test speed of the movement front end 200, reduce the test efficiency of the first detection member 300 and the second detection member 400, and further reduce the working efficiency of the test device and increase the energy consumption. During the detection process of the test device, the rack 100 needs to control the movement of the movement front end 200, so that the first detection member 300 and the second detection member 400 detect different Mark points on the circuit board. In the traditional technology, because two driving members are arranged on the movement front end 200 to drive the first detection member 300 and the second detection member 400 respectively, the movement front end 200 is relatively heavy, which greatly affects the flexibility of the movement front end 200.

[0052] In the embodiment of the present application, since the first detection member 300 and the second detection member 400 on the motion front end 200 are both implemented by one second driving member 600 to realize the detection work of both, the number of driving members installed on the motion front end 200 is reduced, the weight of the motion front end 200 is greatly reduced, the movement of the motion front end 200 on the rack 100 is more flexible, and therefore, in the process of controlling the movement of the motion front end 200 by the rack 100, the movement speed of the motion front end 200 is improved, so that the first detection member 300 and the second detection member 400 can reach the corresponding Mark points faster to perform the test, thereby improving the test speed and test efficiency of the test device.

[0053] In some embodiments, the second detection member 400 is magnetically attracted to the first connecting member 210 or the second connecting member 310, and the magnetic attraction can meet the temporary fixation between the second detection member 400 and the first connecting member 210, or the temporary fixation between the second detection member 400 and the second connecting member 310, so as to realize the position regulation of the second detection member 400 by the switching assembly 500.

[0054] Specifically, in some embodiments, a magnet is connected to the first connecting member 210, the second connecting member 310, or connected to the side of the second detection member 400 facing the first detection member 300 and connected to the side of the second detection member 400 facing the second connecting member 310, so that the second detection member 400 is attached to the first connecting member 210 or the second connecting member 310. Since the second detection member 400 is attached to the first connecting member 210 or the second connecting member 310, the contact area between the second detection member 400 and the first connecting member 210, and the second detection member 400 and the second connecting member 310 is increased, and therefore, the adsorption force between the second detection member 400 and the first connecting member 210, and the second connecting member 310 is improved.

[0055] In some embodiments, referring to Figure 2 The switching assembly 500 includes a third driving member 530 connected to the clamping member 510, and the third driving member 530 drives the clamping member 510 in a second direction to move away from or close to the second detection member 400, so as to make the clamping member 510 clamp the second detection member 400 or separate the clamping member 510 from the second detection member 400.

[0056] When the clamping member 510 needs to clamp the second detection member 400, the third driving member 530 drives the clamping member 510 to move close to the detection member, so that the clamping member 510 clamps the second detection member 400; when the clamping member 510 needs to be separated from the second detection member 400, the third driving member 530 drives the clamping member 510 clamped on the second detection member 400 to move away from the second detection member 400 in the second direction, so that the clamping member 510 and the second detection member 400 are separated, and thus the control of the clamping or separation of the clamping member 510 and the second detection member 400 can be realized by arranging the third driving member 530.

[0057] In some embodiments, one side of the clamping member 510 facing the second detection member 400 is provided with a groove 511, and the groove 511 has two opposite side walls in the sliding direction of the second detection member 400; one side of the second detection member 400 facing the clamping member 510 is provided with a protruding portion 410, and the protruding portion 410 can be accommodated in the groove 511; or, one side of the second detection member 400 facing the clamping member 510 is provided with a groove 511, and the groove 511 has two opposite side walls in the sliding direction of the second detection member 400; one side of the clamping member 510 facing the second detection member 400 is provided with a protruding portion 410, and the protruding portion 410 can be accommodated in the groove 511. Among them, Figure 1 For example, one side of the clamping member 510 facing the second detection member 400 is provided with a groove 511, and one side of the second detection member 400 facing the clamping member 510 is provided with a protruding portion 410.

[0058] Since the groove 511 has two opposite side walls in the first direction, when the protruding portion 410 is accommodated in the groove 511, the two opposite side walls of the groove 511 will limit the movement of the protruding portion 410 in the first direction, and when the first driving member 520 drives the clamping member 510 to move in the first direction, the abutting action of the two opposite side walls of the groove 511 on the protruding portion 410 makes the clamping member 510 and the second detection member 400 can move synchronously in the first direction, thereby realizing the position regulation of the second detection member 400 in the first direction by the switching assembly 500.

[0059] In some embodiments, referring to Figure 1 Or 2, the test device comprises a rack 100, the bottom end of the switching assembly 500 is installed on one side of the rack 100, and the top end of the movement front end 200 is installed on the other side of the rack 100.

[0060] It can be understood that the motion front end 200 and the switching assembly 500 are arranged on the opposite sides of the rack 100 respectively, so as to avoid the problem that the weight of the switching assembly 500 is superimposed on the motion front end 200, which causes the motion front end 200 to be relatively heavy during the detection work, so as to maintain the overall weight of the motion front end 200 (including the first detection piece 300, the second detection piece 400 and the second driving piece 600 connected to the motion front end 200).

[0061] In order to reduce the space occupied by the motion front end 200, the first detection piece 300, the second detection piece 400 and the second driving piece 600 in the first direction, in some embodiments, with reference to Figure 1 、 Figure 2 , along the arrangement direction of the first detection piece 300 and the second detection piece 400, the driving assembly is located on the side of the first detection piece 300 away from the second detection piece 400. It can be understood that, since the motion front end 200 needs to control the first detection piece 300 and the second detection piece 400 to move in the first direction, the above arrangement can improve the movement space of the first detection piece 300 and the second detection piece 400 in the first direction.

[0062] In order to realize the guidance of the second detection piece 400 along the first direction, in some embodiments, with reference to Figure 1 and Figure 3 , Figure 3 is a schematic view of the slide rail of the first aspect embodiment of the present application, the motion front end 200 includes a slide rail 220, the slide rail 220 is arranged along the first direction, the second detection piece 400 is slidably connected to the slide rail 220 along the first direction, and the slide rail 220 is used to guide the movement of the second detection piece 400 along the first direction.

[0063] The slide rail 220 is arranged on the motion front end 200 along the first direction, and the second detection piece 400 is slidably connected to the slide rail 220, so that when the switching assembly 500 drives the second detection piece 400 to move along the first direction, the slide rail 220 can guide the second detection piece 400 in the first direction.

[0064] It can be understood that, in order to realize the guidance of the first detection piece 300 along the first direction, those skilled in the art can also realize it by making corresponding settings to the prior art, and the specific implementation can refer to the above-mentioned guidance mode of the second detection piece 400, but is not limited to the above-mentioned guidance mode of the second detection piece 400, which will not be described in detail here.

[0065] For the test device of the second aspect embodiment of the present application, with reference to Figure 4 and Figure 5 , Figure 4 is a schematic view of the second detection piece in the working state of the second aspect embodiment of the present application, Figure 5The first detection member of the second aspect of the present application is in a working state. The test device comprises a moving front end 200, a first detection member 300, a second detection member 400, a clamping assembly 501, and a driving assembly. The moving front end 200 is provided with a first connecting member 210. The first detection member 300 is slidably connected to the moving front end 200 in a first direction to approach or move away from the circuit board. The side of the first detection member 300 protrudes and is provided with a second connecting member 310. The second detection member 400 is slidably connected to the moving front end 200 in the first direction to approach or move away from the circuit board. The second detection member 400 is located on the side of the first detection member 300 and faces the second connecting member 310. The second detection member 400 is magnetically attracted to the first connecting member 210 and the second connecting member 310. The magnetic attraction force between the second detection member 400 and the first connecting member 210 is smaller than the magnetic attraction force between the second detection member 400 and the second connecting member 310. The detection end of the second detection member 400 protrudes relative to the detection end of the first detection member 300. The clamping assembly 501 comprises a clamping member 510 and a third driving member 530. The third driving member 530 is connected to the clamping member 510 and is used to drive the clamping member 510 to move away from or approach the second detection member 400, so that the clamping member 510 clamps or moves away from the second detection member 400. The driving assembly is installed on the moving front end 200. The driving assembly comprises a second driving member 600. The second driving member 600 is connected to the first detection member 300 and can drive the first detection member to move in the first direction alone by overcoming the magnetic attraction force between the second detection member 400 and the second connecting member 310, or drive the second detection member 400 separated from the clamping member 510 to move synchronously with the first detection member 300 by overcoming the magnetic attraction force between the second detection member 400 and the first connecting member 210. The detection end of the second detection member 400 protrudes relative to the detection end of the first detection member 300. When the clamping member 510 clamps the second detection member 400, the second driving member 600 drives the first detection member 300 to move in the first direction, and the second detection member 400 and the first detection member 300 are separated. When the clamping member 510 is separated from the second detection member 400, the second driving member 600 drives the first detection member 300 to move, and the second detection member 400 moves synchronously with the first detection member 300.

[0066] Since the first detection member 300 and the second detection member 400 on the motion front end 200 are both implemented by one second driving member 600 to realize the detection work of the two, compared with the prior art in which two driving members are arranged on the motion front end 200 to separately drive the first detection member 300 and the second detection member 400, the number of driving members installed on the motion front end 200 is reduced, the weight of the motion front end 200 is greatly reduced, the movement of the motion front end 200 on the rack 100 is more flexible, and thus the movement speed of the motion front end 200 is improved in the process of controlling the movement of the motion front end 200 by the rack 100, so that the first detection member 300 and the second detection member 400 can reach the corresponding Mark points to perform the test faster, thereby improving the test speed and test efficiency of the test device.

[0067] Specifically, the embodiment of the present application provides another implementation manner of "realizing the detection work of the first detection member 300 and the second detection member 400 by one second driving member 600". When the first detection member 300 needs to be used for detection, referring to Figure 5 , the third driving member 530 drives the clamping member 510 to move towards the second detection member 400 and makes the clamping member 510 clamped on the second detection member 400, at this time, the second driving member 600 drives the first detection member 300 to move, and since the second detection member 400 is clamped by the clamping member 510, the first detection member 300 and the second detection member 400 are separated, the first detection member 300 moves alone along the first direction, and the detection on the circuit board is realized; when the second detection member 400 needs to be used for detection, referring to FIG. 4, the third driving member 530 drives the clamping member 510 clamped on the second detection member 400 to move away from the second detection member 400, so that the clamping member 510 and the second detection member 400 are separated, at this time, the second driving member 600 drives the first detection member 300 to move, since the magnetic attraction force between the second detection member 400 and the first connecting member 210 is smaller than the magnetic attraction force between the second detection member 400 and the second connecting member 310, the first detection member 300 can drive the second detection member 400 to move along the first direction synchronously through magnetic attraction, and since the detection end of the second detection member 400 is protruded than the detection end of the first detection member 300, when the first detection member 300 and the second detection member 400 move towards the circuit board, the second detection member 400 can contact the circuit board first to realize the detection work of the second detection member 400.

[0068] According to the test device of the third aspect embodiment of the present application, referring to Figure 1The test device includes at least one test device as described above, and a conveying device (not shown) mounted on the frame 100 and connected with the moving head 200, and the conveying device is capable of driving the moving head 200 to move in a horizontal plane in the second direction.

[0069] The conveying device can be a multi-axis module or a robot. By mounting the moving head 200 on the conveying device, the test device can test different test objects or different positions of the test object, and the conveying device can drive different moving heads 200 to move, so that multiple test devices can test different Mark points of the test object or the same Mark point, so that the test device can be compatible with different types of test requirements and improve the test efficiency of the test device.

[0070] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
