[0025] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0026] Please refer to Figures 1 to 3, the detection device 100 includes: a mounting base 10, a carrier 20, a detection mechanism 30, and a pressing mechanism 40. The carrier 20, the pressing mechanism 40, and the limiting component 50 are all arranged on the mounting base 10. The carrier 20 is provided with a carrier groove 201 for carrying the circuit board to be tested. The detection mechanism 30 includes a detection circuit and at least two probes (not shown in the figure). The at least two probes are fixedly arranged at intervals in the carrier groove 201. The detection circuit is connected to the at least two probes. The pressing mechanism 40 is arranged on the mounting base 10. The pressing mechanism 40 abuts against the circuit board to be tested, so that the at least two probes keep abutting against the solder joints of the circuit board to be tested. Among them, the detection circuit is used to detect the solder joints of the circuit board to be tested through the at least two probes.
[0027] Please continue to refer to Figure 3 , the pressing mechanism 40 includes a first driving component 401, a pressing plate 402, and a mounting arm 403. The mounting arm 403 is arranged on the mounting base 10. The first driving component 401 is arranged on the mounting arm 403. The first driving component 401 is connected to the pressing plate 402. The first driving component 401 is used to drive the pressing plate 402 to reciprocate along the mounting arm 403, so as to drive the pressing plate 402 to move towards the carrier 20 to abut against the circuit board to be tested, or drive the pressing plate 402 to move away from the carrier 20 to separate the pressing plate 402 from the circuit board to be tested. For example: when it is necessary to detect the circuit board to be tested, the first driving component 401 starts to work, driving the pressing plate 402 to move away from the carrier 20 to facilitate the staff to place the circuit board to be tested on the carrier, and then driving the pressing plate 402 to move towards the carrier 20. The pressing plate 402 gradually approaches the circuit board to be tested and finally abuts against the circuit board to be tested to ensure a stable connection between the probe and the solder joint of the circuit board to be tested. When the detection is completed, the first driving component 40 drives the pressing plate 402 to move away from the carrier 20, and the pressing plate 402 gradually separates from the circuit board to be tested, facilitating the removal of the circuit board for the next operation.
[0028] Please refer to Figure 4, the first driving assembly 401 includes a first driving cylinder 411 and a cross arm 412. The first driving cylinder 411 is fixed to the other end of the mounting arm 403 away from the mounting base 10. The cross arm 412 is fixed to the first driving cylinder 411. The pressing plate 402 is fixed to the cross arm 412. The first driving cylinder 411 is used to drive the cross arm 412 to move, thereby driving the pressing plate 402 to move. When detection is required, the first driving cylinder 411 drives the cross arm 412 to move. Since the cross arm 412 is fixedly connected to the pressing plate 402, the movement of the cross arm 412 will drive the pressing plate 402 to move synchronously. When the pressing plate 402 moves downward, the pressing plate 402 gradually approaches the circuit board to be tested on the carrier 20. When the pressing plate 402 contacts the circuit board to be tested and applies a certain pressure, the circuit board to be tested will be fixed on the carrier 20, so as to ensure that the circuit board to be tested does not displace or shake during the detection process. After the detection is completed, the first driving cylinder 411 will drive the cross arm 412 and the pressing plate 402 to move upward to release the pressure on the circuit board to be tested.
[0029] In some embodiments, the carrier 20 is slidably disposed on the mounting base 10, and the carrier 20 can reciprocate between a first position and a second position. When the carrier 20 is in the first position, the carrier slot 201 is located below the pressing plate 402. At this time, the pressing plate 402 can move downward to abut against the circuit board to be tested, so that the probe is in close contact with the solder joints on the circuit board. When the carrier 20 is in the second position, the carrier slot 201 deviates from the pressing plate 402 to facilitate the insertion or removal of the circuit board to be tested.
[0030] To prevent the carrier 20 from moving freely when the carrier 20 is in the first position, please refer to Figure 4 and Figure 5 , the detection device 100 further includes a limiting assembly 50. The limiting assembly 50 is used to limit the carrier 20 when the carrier 20 is in the first position.
[0031] In some embodiments, the limiting component 50 includes a limiting block 501 and a limiting cylinder 502. The limiting cylinder 502 is fixed to the mounting base 10. The limiting cylinder 502 is connected to the limiting block 501. A limiting post 511 is provided on the surface of the limiting block 501 facing away from the limiting cylinder 502, and a limiting hole 202 is provided on the side surface of the carrier 20. When the carrier 20 is in the first position, the limiting cylinder 502 can drive the limiting block 501 to move towards the carrier 20, so that when the limiting post 511 is inserted into the limiting hole 202, the carrier 20 is limited. When the carrier 20 needs to be unlocked, the limiting cylinder 502 drives the limiting block 501 to move away from the carrier 20, so that the limiting post 511 is disengaged from the limiting hole 202, and the limitation of the carrier 20 is released.
[0032] Please continue to refer to Figure 4 and Figure 5 , the detection device 100 further includes a position sensor 60 and a controller (not shown in the figure). The position sensor 60 is provided on the mounting base 10, and the position sensor 60 is used to detect whether the carrier 20 is in the first position. The controller is respectively connected to the position sensor 60 and the limiting component 50. The controller is used to control the limiting component 50 to limit the carrier 20 when the position sensor 60 detects that the carrier 20 is in the first position, so as to realize automatic limitation of the carrier 20. Of course, when the lock on the carrier 20 needs to be released, an operation instruction can be sent to the controller, and the controller controls the limiting cylinder 502 to drive the limiting block 501 to move away from the carrier 20, so that the limiting post 511 is disengaged from the limiting hole 202, and the limitation of the carrier 20 is released.
[0033] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 4 , the detection device 100 further includes a mounting cover 80 and a second driving component 90. The mounting cover 80 is fixed to the mounting base 10. The mounting cover 80 and the mounting base 10 together form a receiving cavity 801. The detection mechanism 30 and the pressing mechanism 40 are both located in the receiving cavity 801. The mounting cover 80 is provided with an opening 802, and the opening 802 communicates with the receiving cavity 801. When the carrier 20 is in the first position, the carrier 20 is located in the receiving cavity 801. When the carrier 20 is in the second position, the carrier 20 extends out of the mounting cover 80 from the opening 802. When the carrier 20 extends out of the mounting cover 80 from the opening 802, a circuit board to be tested can be loaded onto the carrier outside the mounting cover 80.
[0034] The second driving component 90 is arranged on the mounting base 10. The second driving component 90 is used to drive the vehicle 20 to move in the direction from the first position to the second position and extend out of the mounting cover 80 through the opening 802. The vehicle 20 will partially or entirely extend out through the opening 802 of the mounting cover 80, so that an operator can operate the vehicle 20 from the outside, such as replacing the circuit board to be tested. In some embodiments, the second driving component 90 is a driving cylinder.
[0035] An embodiment of the present application provides a detection device 100, including a mounting base 10, a vehicle 20, a detection mechanism 30 and a pressing mechanism 40; the vehicle 20 is arranged on the mounting base 10, and the vehicle 20 is provided with a carrier groove 201 for carrying the circuit board to be tested; the detection mechanism 30 includes a detection circuit and at least two probes, the at least two probes are fixedly arranged at intervals in the carrier groove 201, and the detection circuit is connected with the at least two probes; the pressing mechanism 40 is arranged on the mounting base 10, and the pressing mechanism 40 abuts against the circuit board to be tested so that the at least two probes keep connected with the circuit board to be tested; wherein, the detection circuit is used to be connected with the circuit board to be tested through the at least two probes to detect the circuit board to be tested. By placing the circuit board in the carrier groove 201, the pressing mechanism 40 works to abut against the circuit board to be tested to ensure that the probes are in contact with the test points of the circuit board. The detection circuit is connected with the circuit board through the probes to start the test. After the test is completed, the pressing mechanism 40 releases, the circuit board is taken out, and the next round of test is carried out. Multiple solder joints of the circuit board can be detected at one time, improving the efficiency and accuracy of the solder joint detection of the circuit board.
