[0036] In this embodiment, each detection module 3 can be driven individually by the corresponding driving component 2, so that when retesting defective products, it is only necessary to drive the detection module 3 corresponding to the defective product to move so that the probe 32 of the detection module 3 is pressed against the detection point of the defective product. The detection module 3 corresponding to the good product does not need to be driven. In this way, when retesting, the good product will not be pressed multiple times, thereby effectively avoiding the appearance defects of the good product.

[0037] It should be noted that one detection module 3 may have multiple probes 32, and the axes of the probes 32 in one detection module 3 may be parallel to each other. In addition, the structural arrangement of each detection module 3 may be the same, and the axes of the probes 32 of each detection module 3 may also be parallel to each other.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the driving assembly 2 includes a driving unit 21, a driving member 22, a pressing member 23 and a reset member 24; wherein the driving unit 21 is used to drive the driving member 22 to move in the positive direction of the first direction, so that the driving member 22 can squeeze the pressing member 23, and then the pressing member 23 moves in the positive direction of the second direction; when the pressing member 23 moves in the positive direction of the second direction, it can drive the needle mold 31 to move in the positive direction of the second direction, so that the probe 32 electrically contacts the detection point of the circuit board to be tested; when the needle mold 31 moves in the positive direction of the second direction, it can apply force to the reset member 24, so that the reset member 24 produces elastic deformation; the second direction is parallel to the axial direction of the probe 32, and the angle between the second direction and the first direction is greater than 0 degree and less than 180 degrees.

[0043] like Figure 3 As shown, the guide hole 221 may be arranged to be inclined, and along the positive direction of the first direction, the guide hole 221 gradually approaches the needle mold 31, that is, the guide hole 221 gradually inclines downward.

[0044] like Figure 3 As shown, the driving member 22 includes a first driving plate 222, a second driving plate 223 and a connecting plate 224. The first driving plate 222 and the second driving plate 223 are arranged at intervals. The connecting plate 224 connects the first driving plate 222 and the second driving plate 223 respectively. The first driving plate 222 and the second driving plate 223 are both provided with guide holes 221. Two guide posts 232 are also provided, and one guide post 232 is located in one guide hole 221, so that the movement of the pressing rod 231 along the first direction can be more stable.

[0045] In addition, the connection plate 224 is connected to the driving unit 21. The first driving plate 222 and the second driving plate 223 are arranged at intervals along a third direction, wherein the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction.

[0046] In one embodiment, the pressing rod 231 and the guide post 232 can both be cylindrical structures, and the axis of the guide post 232 is perpendicular to the axis of the pressing rod 231. The guide post 232 is arranged at the upper end of the pressing rod 231, and the lower end of the pressing rod 231 contacts the needle mold 31. When the pressing rod 231 moves downward (i.e., moves in the positive direction of the second direction), the needle mold 31 can be pressed, so that the probe 32 can be driven to move downward, so that it contacts the detection point of the circuit board to be tested. When the pressing rod 231 moves upward, no force is applied to the needle mold 31.

[0047] In one embodiment, when the needle mold 31 moves in the positive direction of the second direction, the needle mold 31 gradually approaches the support member 1, that is, the needle mold 31 is located above the support member 1. That is, the needle mold 31 reciprocates along the axial direction of the probe 32, and can approach or move away from the support member 1, and when the needle mold 31 moves close to the support member 1, the probe 32 can electrically contact the detection point of the circuit board to be tested.

And / or, the support member 1 is provided with a second mounting hole, the second end of the reset member 24 is installed in the second mounting hole, the first end of the reset member 24 extends into the second mounting hole and contacts the pin mold 31.

[0050] When a first mounting hole is provided on the needle mold 31, a second mounting hole is provided on the support member 1, the first end of the reset member 24 is located in the first mounting hole, and the second end of the reset member 24 is located in the second mounting hole, the first end of the reset member 24 can contact the bottom surface of the first mounting hole, and the second end of the reset member 24 can contact the bottom surface of the second mounting hole.

[0051] In one embodiment, when the needle mold 31 is located above the support member 1, a avoidance hole is provided on the support member 1, and the probe 32 can pass through the support member 1 from the avoidance hole to electrically contact the detection point of the circuit board to be tested. It should be understood that the avoidance hole penetrates the support member 1 along the second direction, wherein when the number of the probes 32 is multiple, the number of the avoidance holes is also multiple, one probe 32 corresponds to one avoidance hole, and the probe 32 can pass through the support member 1 from the avoidance hole corresponding thereto.

[0052] In addition, when the support member 1 is provided with a second mounting hole, the second mounting hole and the avoidance hole may be coaxially arranged, and the diameter of the second mounting hole is larger than the diameter of the avoidance hole, and the two form a stepped hole.

[0053] like Figure 1As shown, in one embodiment, a receiving groove 11 is provided on the support member 1, the needle mold 31 is installed in the receiving groove 11, and the avoidance hole is provided on the bottom surface of the receiving groove 11.

Both the driving component 2 and the needle mold 31 are located between the top plate 5 and the support plate 12, and the probe 32 can extend out of the side of the support plate 12 away from the top plate 5 so as to conflict with the detection point of the circuit board to be tested. The top plate 5 can be used to connect the corresponding driving module, and the driving module can drive the entire detection module to approach the carrier on which the circuit board to be tested is placed. When the detection module 100 as a whole approaches the carrier for a certain distance, the probe 32 of each detection module 3 has not yet conflicted with the detection point of the circuit board to be tested. Then, the corresponding driving component 2 drives the corresponding detection module 3 to move in the positive direction of the first direction, so that the probe 32 of the detection module 3 conflicts with the detection point of the circuit board to be tested.

[0057] The support member 1 is provided with an assembly hole, and the connection column 4 and the assembly hole are interference fit, and the connection column 4 and the connection hole can be clearance fit. In addition, the limiting member 6 can be a limiting copper sleeve.

[0058] Of course, in other embodiments, in order to prevent the needle mold 31 and the support member 1 from being out of engagement, a connecting hole may be provided on the support member 1, and the connecting hole penetrates the support member 1 along the axial direction of the probe 32; the end of the connecting column 4 away from the stop block is connected to the needle mold 31, and the connecting column 4 is passed through the connecting hole, and when the needle mold 31 moves in a direction away from the support member 1, it can drive the stop block to move, so that the stop block can collide with the support member 1. In this case, the assembly hole is provided on the needle mold 31.

[0059] like Figure 1 As shown, in one embodiment, the detection module 100 also includes a cover plate 7, which is connected to the support plate 12 and covers the opening of the receiving groove 11 formed on the upper surface of the support plate 12, so that the needle mold 31 can be limited in the receiving groove 11.

[0062] In addition, a hollow area is provided on the mounting seat 81, and the hollow area is connected to the avoidance space. After the pressing rod 231 passes through the mounting seat 81 from the hollow area, it passes through the cover plate 7 from the avoidance space.

[0063] The mounting seat 81 includes a first mounting plate 811 and a second mounting plate 812. The first mounting plate 811 is mounted on the surface of the cover plate 7 away from the support plate 12, the second mounting plate 812 is mounted on the surface of the first mounting plate 811 away from the cover plate 7, and the track is mounted on the surface of the second mounting plate 812 away from the first mounting plate 811.

[0065] like Figure 1 As shown, in one embodiment, the detection module 100 further includes a guide rod 10, which is mounted on the support member 1. When the circuit board to be tested is tested, when the support member 1 is close to the carrier, the guide rod 10 can cooperate with the guide hole on the carrier, so that the relative position of the support member 1 and the carrier can be limited in the horizontal direction, thereby enabling the probe to be more accurately aligned with the circuit board to be tested on the carrier. In addition, the guide rod 10 can be installed below the support plate 12.

[0066] An embodiment of the present invention further provides a detection device, which includes the detection module 100 described in any one of the above embodiments.

When working, the probes 32 of each detection module 3 can simultaneously contact the detection points of the corresponding circuit boards to be tested in the material tray, so as to detect all the circuit boards to be tested at the same time.

[0069] In one embodiment, the detection device further includes a driving module, which is connected to the support member 1 and is used to drive the support member 1 to reciprocate along the axial direction of the probe 32. When working, the driving module first drives the support member 1 to move a certain distance in the positive direction of the first direction, and then drives all the probes 32 and 31 blocks to approach the material tray. At this time, the probes 32 of each detection module 3 have not yet collided with the detection point of the circuit board to be tested. Then, the corresponding driving component 2 drives the corresponding detection module 3 to move in the positive direction of the first direction, so that the probe 32 of the detection module 3 conflicts with the detection point of the circuit board to be tested.

[0070] The driving module is connected to the top plate 5 and is located on a side of the top plate 5 away from the supporting plate 12 .
