Description

Technical Field

[0001] This utility model belongs to the field of PCB board testing technology, and in particular relates to a board calibration device and PCB board testing equipment. Background Technology

[0002] Before electrical testing of a PCB (Printed Circuit Board), it is generally necessary to photograph the marked points on the PCB to determine their positions, so as to adjust the test position of the PCB. However, because high-precision cameras have a small field of view, if the PCB is placed on the test tray with a large deviation, the marked points may not be in the camera's field of view. In this case, it is necessary to calibrate the PCB on the test tray so that it is centered on the test tray.

[0003] In existing technologies, two opposing calibrators are typically used to calibrate the PCB board by placing it between them. However, PCB boards of different part numbers have different length and width dimensions, and existing PCB board calibrator methods require manual adjustment of the calibrator width every time the PCB board part number is changed, which is cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a PCB board calibration device and PCB board testing equipment, addressing the technical problem of the complex operation of existing PCB board calibration methods.

[0005] To solve the above-mentioned technical problems, on the one hand, this utility model provides a calibration plate device, including a calibration plate support, a first calibration plate driving mechanism, a second calibration plate driving mechanism, a first calibration component, and a second calibration component. The calibration plate support is used to carry materials. The output end of the first calibration plate driving mechanism is connected to the calibration plate support. The first calibration plate driving mechanism is used to drive the calibration plate support to reciprocate between the calibration plate position and the avoidance position.

[0006] The second calibration plate driving mechanism is installed on the calibration plate bracket. The output end of the second calibration plate driving mechanism is connected to the first calibration member and the second calibration member. At the calibration plate position, the second calibration plate driving mechanism can drive the first calibration member and the second calibration member to move closer to or further away from each other in order to calibrate the material carried on the calibration plate bracket.

[0007] According to an embodiment of the present invention, a calibration plate device is provided, wherein a first calibration plate driving mechanism drives a calibration plate support to reciprocate between a calibration plate position and a clearance position.

After calibration is completed, driven by the second calibration plate driving mechanism, the first and second calibration members are moved away from each other. At this time, the calibrated material can be detached from the calibration plate support and transferred to a material conveying device for subsequent testing.

[0059] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0060] like Figures 1 to 4 As shown, the alignment device 10 provided in this embodiment of the present invention includes an alignment support 1, a first alignment drive mechanism 2, a second alignment drive mechanism 3, a first alignment component 4, and a second alignment component 5. The alignment support 1 is used to carry the material 20. The output end of the first alignment drive mechanism 2 is connected to the alignment support 1. The first alignment drive mechanism 2 is used to drive the alignment support 1 to reciprocate between the alignment position and the avoidance position.

[0061] The second calibration plate drive mechanism 3 is installed on the calibration plate support 1. The output end of the second calibration plate drive mechanism 3 is connected to the first calibration member 4 and the second calibration member 5. When the calibration plate support 1 is in the calibration plate position, the second calibration plate drive mechanism 3 can drive the first calibration member 4 and the second calibration member 5 to move closer or further away from each other in order to calibrate the material 20 carried on the calibration plate support 1.

[0062] The calibration device 10 provided in this embodiment of the utility model is equipped with a first calibration drive mechanism 2 to drive the calibration support 1 to reciprocate between the calibration position and the avoidance position. When the calibration support 1 is in the calibration position, the material 20 can be supported on the calibration support 1. Then, driven by the second calibration drive mechanism 3, the first calibration member 4 and the second calibration member 5 are brought closer to each other to calibrate the material 20 supported on the calibration support 1, so that the material 20 is located in the center position of the calibration support 1. After the calibration is completed, driven by the second calibration drive mechanism 3, the first calibration member 4 and the second calibration member 5 are moved away from each other. At this time, the calibrated material 20 can be removed from the calibration support 1 and can be transferred to the material 20 conveying device for subsequent testing. Since the material 20 has been calibrated, the positional deviation of the material 20 transferred to the material 20 conveying device will be small, which facilitates the camera to take pictures of the marked points. After the calibrated material 20 is removed from the calibration plate support 1, the calibration plate support 1 can move to an avoidance position under the drive of the first calibration plate drive mechanism 2, so as to avoid the calibration plate device 10 from interfering with the subsequent material 20 conveying and testing. The calibration method of this calibration plate device 10 can reduce debugging time, is convenient and quick, has high accuracy, and is also compatible with the calibration of materials 20 of various sizes.

[0063] In one embodiment, such as Figures 1 to 4 As shown, the first calibration plate driving mechanism 2 is used to drive the calibration plate support 1 to move along the first direction z, and the second calibration plate driving mechanism 3 is used to drive the first calibration member 4 and the second calibration member 5 to move closer to or further away from each other along the second direction x. The first direction z intersects the second direction x.

[0064] The alignment plate position and the avoidance position are spaced apart along the first direction z. The alignment plate support 1 is driven to move along the first direction z by the first alignment plate driving mechanism 2, so that the alignment plate support 1 reciprocates between the alignment plate position and the avoidance position. The first correction member 4 and the second correction member 5 are arranged opposite each other along the second direction x. The first correction member 4 and the second correction member 5 are driven to move closer or further away from each other along the second direction x by the second alignment plate driving mechanism 3, so as to achieve the correction of the material 20.

[0065] exist Figures 1 to 4 In the embodiment shown, the first direction z intersects with the second direction x. Specifically, the first direction z can be perpendicular to the second direction x, so that the movement direction of the calibration plate bracket 1 intersects with the movement direction of the first calibration member 4 and the second calibration member 5, so that the positions of the first calibration member 4 and the second calibration member 5 can be adjusted in the two-dimensional plane constructed by the first direction z and the second direction x.

[0066] In other embodiments not shown in the figure, the first direction may be parallel to the second direction. In this case, the movement direction of the calibration plate bracket is parallel to the movement direction of the first and second calibration members, so that the positions of the first and second calibration members can be adjusted in a single direction.

[0067] In one embodiment, such as Figure 1 and Figure 4 As shown, the first calibration plate driving mechanism 2 includes a first calibration driving component 21, a calibration lead screw 22, a first calibration frame 23 and a second calibration frame 24. The first calibration driving component 21 is installed on the first calibration frame 23 and is connected to the calibration lead screw 22. The first calibration driving component 21 is used to drive the calibration lead screw 22 to rotate.

[0068] The second calibration frame 24 is threadedly connected to the calibration screw 22, and the second calibration frame 24 can slide relative to the first calibration frame 23 along the first direction z.

[0069] The calibration plate bracket 1 is installed on the second calibration frame 24.

[0070] When the first calibration drive 21 drives the calibration screw 22 to rotate, the second calibration frame 24 is threadedly connected to the calibration screw 22, so that the second calibration frame 24 can slide relative to the first calibration frame 23 in the first direction z, thereby driving the calibration plate bracket 1 installed on the second calibration frame 24 to move in the first direction z, so that the calibration plate bracket 1 reciprocates between the calibration plate position and the avoidance position.

[0071] In one embodiment, such as Figure 1 and Figure 4 As shown, the first correction drive 21 includes a first correction motor, the output shaft of which is connected to the correction lead screw 22 to drive the correction lead screw 22 to rotate and control the position of the correction plate bracket 1 in the first direction z.

[0072] The first calibration motor can be a servo motor. Servo motors can be parametrically adjusted, which can reduce debugging time, make calibration convenient and quick, and achieve higher accuracy.

[0073] In one embodiment, such as Figure 1 As shown, the second calibration frame 24 includes a first calibration connector 241, a second calibration connector 242, and a third calibration connector 243. The first calibration connector 241 is disposed between the second calibration connector 242 and the first calibration frame 23 along the first direction z. The third calibration connector 243 is connected between the first calibration connector 241 and the second calibration connector 242.

[0074] The first calibration connector 241 is threadedly connected to the calibration screw 22, and the calibration plate bracket 1 is installed on the second calibration connector 242.

[0075] The second calibration frame 24 is threadedly connected to the calibration lead screw 22 by connecting the first calibration connector 241 to the calibration lead screw 22. The calibration plate bracket 1 is installed on the second calibration frame 24 by mounting the calibration plate bracket 1 to the second calibration connector 242.

[0076] In one embodiment, such as Figure 1 As shown, the correction screw 22 is positioned between the first correction member 4 and the second correction member 5 along the second direction x, so that the correction screw 22 is located at a relatively central position of the correction plate support 1 along the second direction x, and at a relatively central position when the material 20 is being corrected, so as to drive and support the correction plate support 1 more smoothly.

[0077] In one embodiment, such as Figure 1 and Figure 4 As shown, the first calibration plate driving mechanism 2 also includes a calibration guide rod 25, which is mounted on the first calibration frame 23, and the second calibration frame 24 is slidably connected to the calibration guide rod 25 along the first direction z.

[0078] By setting the correction guide rod 25, the movement of the second correction frame 24 along the first direction z can be guided, and the deflection of the second correction frame 24 when it moves along the first direction z can also be avoided.

[0079] In one embodiment, such as Figure 1 and Figure 4 As shown, the correction screw 22 is positioned between the first correction member 4 and the second correction member 5 along the second direction x.

[0080] Multiple correction guide rods 25 are provided. At least one correction guide rod 25 is provided between the first correction member 4 and the correction screw 22 along the second direction x. At least one correction guide rod 25 is provided between the second correction member 5 and the correction screw 22 along the second direction x.

[0081] When multiple correction guide rods 25 are provided, by setting at least one correction guide rod 25 between the first correction member 4 and the correction screw 22 along the second direction x, and setting at least one correction guide rod 25 between the second correction member 5 and the correction screw 22 along the second direction x, the movement guidance of the second correction frame 24 can be provided from both sides of the correction screw 22 at least along the second direction x, so as to better avoid the deflection of the second correction frame 24 when it moves along the first direction z.

[0082] In an embodiment not shown in the figure, at least two correction guide rods 25 may be respectively disposed on opposite sides of the first correction member 4 along the third direction y to provide motion guidance for the second correction frame 24 and better prevent the second correction frame 24 from deflecting when it moves along the first direction z.

[0083] In one embodiment, such as Figure 1 As shown, the lead screw 22 extends along the first direction z; and / or, the guide rod 25 extends along the first direction z.

[0084] By extending the correction screw 22 along the first direction z, the second correction frame 24 is provided with motion drive along the first direction z. By extending the correction guide rod 25 along the first direction z, the second correction frame 24 is provided with motion guide along the first direction z.

[0085] In one embodiment, such as Figure 4 As shown, the calibration device 10 also includes a calibration plate limiting frame 6, a calibration plate sensing element 7, a first calibration plate sensor 8, and a second calibration plate sensor 9. The calibration plate limiting frame 6 is installed on the first calibration frame 23. The first calibration plate sensor 8 and the second calibration plate sensor 9 are installed at intervals along the first direction z on the calibration plate limiting frame 6. The first calibration plate sensor 8 is provided with a first sensing space, and the second calibration plate sensor 9 is provided with a second sensing space. The calibration plate sensing element 7 is installed on the second calibration frame 24.

[0086] The second calibration frame 24 can drive the calibration plate sensor 7 to move along the first direction z, thereby enabling the calibration plate sensor 7 to approach the first sensing space or the second sensing space.

[0087] At the calibration board position, the calibration board sensor 7 is located within the first sensing space.

[0088] In the avoidance position, the calibration board sensor 7 is located within the second sensing space.

[0089] When the calibration plate sensor 7 is within the first sensing space, the first calibration plate sensor 8 can detect the calibration plate sensor 7. At this time, the first calibration plate drive mechanism 2 stops driving the calibration plate support 1, causing the calibration plate support 1 to remain in the calibration plate position, thus realizing the calibration of the material 20. When the calibration plate sensor 7 is within the second sensing space, the second calibration plate sensor 9 can detect the calibration plate sensor 7. At this time, the first calibration plate drive mechanism 2 stops driving the calibration plate support 1, causing the calibration plate support 1 to remain in the avoidance position, thus preventing the calibration plate device 10 from interfering with subsequent material conveying and testing.

[0090] In one embodiment, the distance along the first direction z between the calibration plate position and the avoidance position is not less than the dimension of the first calibration member 4 along the first direction z, and the distance along the first direction z between the calibration plate position and the avoidance position is not less than the dimension of the second calibration member 5 along the first direction z. For example, the first direction z is set as the height direction, whereby the dimension of the first calibration member 4 along the first direction z is the height of the first calibration member 4, and the dimension of the second calibration member 5 along the first direction z is the height of the second calibration member 5.

[0091] By ensuring that the distance between the calibration plate position and the avoidance position along the first direction z is not less than the dimension of the first calibration member 4 along the first direction z, and not less than the dimension of the second calibration member 5 along the first direction z, the interference of the first calibration member 4 and the second calibration member 5 on the subsequent material 20 conveying and testing is avoided.

[0092] In one embodiment, multiple alignment plate positions can be set at intervals along a first direction z, with each alignment plate position located on the same side of the avoidance position. Correspondingly, multiple first alignment plate sensors 8 can be set, and the multiple first alignment plate sensors 8 are installed at intervals along the first direction z on the alignment plate limiting frame 6. The multiple first alignment plate sensors 8 are arranged one-to-one with the multiple alignment plate positions, and each first alignment plate sensor 8 is provided with a first sensing space. Thus, it can be applied to a material transport device having multiple transport pallets that are transported alternately, and the multiple transport pallets are spaced apart along the first direction z.

[0093] For example, if the material transport device has two transport pallets that are transported alternately, including a first pallet and a second pallet, and the first pallet and the second pallet are spaced apart along the first direction z, then two alignment plate positions can be set at intervals along the first direction z. Correspondingly, two first alignment plate sensors 8 can be set. The two first alignment plate sensors 8 are installed at intervals along the first direction z on the alignment plate limiting frame 6. The two first alignment plate sensors 8 are set one-to-one with the two alignment plate positions, and each first alignment plate sensor 8 is provided with a first sensing space.

[0094] In one embodiment, if multiple calibration plate positions are provided at intervals along the first direction z, the distance between the calibration plate position closest to the avoidance position and the avoidance position along the first direction z must be no less than the size of the first calibration member 4 along the first direction z and no less than the size of the second calibration member 5 along the first direction z, so as to avoid interference between the first calibration member 4 and the second calibration member 5 on the subsequent material 20 conveying and testing.

[0095] In one embodiment, such as Figures 1 to 3 As shown, the second calibration plate driving mechanism 3 includes a second calibration driving component 31, a first calibration synchronous wheel 32, a second calibration synchronous wheel 33, and a calibration synchronous belt 34. The first calibration synchronous wheel 32 and the second calibration synchronous wheel 33 are spaced apart along the second direction x, and the first calibration synchronous wheel 32 and the second calibration synchronous wheel 33 are rotatably connected to the calibration plate bracket 1 respectively. The axis of the first calibration synchronous wheel 32 is parallel to the axis of the second calibration synchronous wheel 33, and the calibration synchronous belt 34 is wound around the first calibration synchronous wheel 32 and the second calibration synchronous wheel 33.

[0096] The second correction drive 31 is mounted on the calibration plate bracket 1. The output end of the second correction drive 31 is connected to the first correction synchronous wheel 32. The second correction drive 31 is used to drive the first correction synchronous wheel 32 to rotate.

[0097] A straight line passing through the center of the first correcting synchronous pulley 32 and the center of the second correcting synchronous pulley 33 is defined as the virtual synchronous line L. The correcting synchronous belt 34 includes a first part 341 located on one side of the virtual synchronous line L along the third direction y and a second part 342 located on the other side of the virtual synchronous line L along the third direction y. The first correcting member 4 is connected to the first part 341, and the second correcting member 5 is connected to the second part 342. The third direction y, the first direction z, and the second direction x are all perpendicular to each other.

[0098] When the second correction drive 31 drives the first correction synchronous pulley 32 to rotate, the correction synchronous belt 34 moves and drives the second correction synchronous pulley 33 to rotate in the opposite direction relative to the first correction synchronous pulley 32. At this time, the movement of the correction synchronous belt 34 can simultaneously drive the first correction component 4 and the second correction component 5 to move in opposite directions along the second direction x, so as to move closer to or further away from each other, thereby achieving the correction of the material 20.

[0099] In one embodiment, such as Figures 1 to 3 As shown, the second correction drive 31 includes a second correction motor, the output shaft of which is connected to the first correction synchronous pulley 32 to drive the first correction synchronous pulley 32 to rotate.

[0100] The second calibration motor can be a servo motor. Servo motors can be parametrically adjusted, which can reduce debugging time, make calibration convenient and quick, and achieve higher accuracy.

[0101] In other embodiments not shown in the figures, the second calibration plate driving mechanism may also include a second calibration drive member and a double-threaded screw. The output end of the second calibration drive member is connected to the double-threaded screw, and the second calibration drive member is used to drive the double-threaded screw to rotate. The two ends of the double-threaded screw are respectively provided with a first thread and a second thread in opposite directions. The first calibration member and the second calibration member are slidably connected to the calibration plate bracket along a second direction, and the first calibration member is threadedly connected to the first thread, and the second calibration member is threadedly connected to the second thread.

[0102] When the second correction drive unit drives the double threaded screw to rotate, since the first thread and the second thread are in opposite directions, the first correction unit and the second correction unit can move in opposite directions along the second direction to move closer to or further away from each other, thereby correcting the material.

[0103] In one embodiment, such as Figures 1 to 3 As shown, the calibration plate device 10 further includes a first calibration connecting block 41, which is slidably connected to the calibration plate support 1 along the second direction x, and is connected to the first part 341. The first calibration member 4 is connected to the first calibration connecting block 41; and / or, the calibration plate device 10 further includes a second calibration connecting block 51, which is slidably connected to the calibration plate support 1 along the second direction x, and is connected to the second part 342. The second calibration member 5 is connected to the second calibration connecting block 51.

[0104] By setting the first calibration connecting block 41, the first calibration component 4 can be indirectly connected to the first part 341 of the calibration timing belt 34. Furthermore, the sliding connection between the first calibration connecting block 41 and the calibration plate bracket 1 makes the movement of the first calibration component 4 smoother and ensures the direction of movement of the first calibration component 4. Similarly, by setting the second calibration connecting block 51, the second calibration component 5 can be indirectly connected to the second part 342 of the calibration timing belt 34. Furthermore, the sliding connection between the second calibration connecting block 51 and the calibration plate bracket 1 makes the movement of the second calibration component 5 smoother and ensures the direction of movement of the second calibration component 5.

[0105] In one embodiment, such as Figures 1 to 3 As shown, a slide rail structure 11 extending along the second direction x can be provided on the calibration plate bracket 1. By sliding the first calibration connecting block 41 and the second calibration connecting block 51 on the slide rail structure 11 respectively, the sliding connection between the first calibration connecting block 41 and the calibration plate bracket 1 and the sliding connection between the second calibration connecting block 51 and the calibration plate bracket 1 can be realized.

[0106] In one embodiment, such as Figure 1As shown, the first correction component 4 is located on the side of the correction plate support 1 facing away from the first correction plate drive mechanism 2, and the second correction component 5 is located on the side of the correction plate support 1 facing away from the first correction plate drive mechanism 2, so that the first correction component 4 and the second correction component 5 are located on the same side of the correction plate support 1, ensuring the correction of the material 20.

[0107] In one embodiment, such as Figure 2 and Figure 3 As shown, the calibration plate support 1 includes a calibration base plate 12, a first calibration side plate 13, and a second calibration side plate 14. The output end of the first calibration plate driving mechanism 2 is connected to the calibration base plate 12, and the second calibration plate driving mechanism 3 is installed on the calibration base plate 12. The first calibration side plate 13 and the second calibration side plate 14 are respectively connected to the side of the calibration base plate 12 facing away from the first calibration plate driving mechanism 2, and the first calibration side plate 13 and the second calibration side plate 14 are spaced apart along a third direction y. The third direction y, the first direction z, and the second direction x are perpendicular to each other to form the calibration plate support 1. Exemplarily, the slide rail structure 11 can be installed on the calibration base plate 12 and is located between the first calibration side plate 13 and the second calibration side plate 14.

[0108] The first correction component 4 is located on the side of the first correction side plate 13 and the second correction side plate 14 facing away from the correction base plate 12, and the second correction component 5 is located on the side of the first correction side plate 13 and the second correction side plate 14 facing away from the correction base plate 12, so that the first correction component 4 and the second correction component 5 are located on the same side of the correction plate support 1, ensuring the correction of the material 20.

[0109] In one embodiment, such as Figures 1 to 4 As shown, the first correction component 4 includes a first correction rod 42, and the second correction component 5 includes a second correction rod 52. The first correction rod 42 and the second correction rod 52 are parallel, and the first correction rod 42 extends along a third direction y. The third direction y, the first direction z, and the second direction x are all perpendicular to each other.

[0110] The material 20 is corrected by making the first correction rod 42 parallel to the second correction rod 52.

[0111] like Figure 5 As shown, this utility model embodiment also provides a PCB board testing device, which includes a machine base 30, a feeding device 40, a material conveying device 50, a testing device 60, a discharging device 70, and the aforementioned board calibration device 10. The feeding device 40, the material conveying device 50, the testing device 60, and the discharging device 70 are sequentially arranged on the machine base 30 along the conveying direction of the material 20. The feeding device 40 is used to provide the material 20, the material conveying device 50 is used to convey the material 20 to the testing device 60, the testing device 60 is used to test the material 20, and the discharging device 70 is used to unload the tested material 20.

[0112] In the alignment plate position, the alignment plate support 1 is close to the material conveying device 50; in the avoidance position, the alignment plate support 1 is far away from the material conveying device 50.

[0113] Material 20 is a PCB board.

[0114] According to the PCB board testing equipment of this utility model embodiment, the board calibration device 10 is equipped with a first calibration drive mechanism 2 to drive the calibration support 1 to reciprocate between the calibration position and the avoidance position. When the calibration support 1 is in the calibration position, the calibration support 1 is close to the material conveying device 50, so that the material 20 provided by the feeding device 40 can be carried on the calibration support 1. Then, driven by the second calibration drive mechanism 3, the first calibration member 4 and the second calibration member 5 are brought closer to each other to calibrate the material 20 carried on the calibration support 1, so that the material 20 is located in the center position of the calibration support 1. After the calibration is completed, driven by the second calibration drive mechanism 3, the first calibration member 4 and the second calibration member 5 are moved away from each other. At this time, the calibrated material 20 can be removed from the calibration support 1 and can be transferred to the material conveying device 50 for subsequent testing by the testing device 60. Since the material 20 has been calibrated, the positional deviation of the material 20 transferred to the material conveying device 50 will be small, which facilitates the camera to take pictures of the marked points. After the calibrated material 20 is removed from the calibration plate support 1, the calibration plate support 1 can move to an avoidance position under the drive of the first calibration plate drive mechanism 2, so that the calibration plate support 1 is away from the material conveying device 50, avoiding interference from the calibration plate device 10 to the subsequent material 20 conveying and testing. The calibration method of this calibration plate device 10 can reduce debugging time, is convenient and quick, has high accuracy, and is also compatible with the calibration of materials 20 of various sizes.

[0115] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
