When the buffer block is squeezed and moved downward again, the sliding point slides in the second slide groove.

At this time, the locking stud is threadedly fixedly connected to the accommodating seat, and the barrier rod is fixed in the current extended state.

[0027] The following is combined with Figure 1-6 This application is described in further detail.

[0028] Example: See also Figure 1-3A semi-automatic circuit board detection device comprises a detection base 1. A start button 2 is installed on the side wall of the detection base 1, and a receiving seat 3 is fixedly mounted above the detection base 1. A receiving groove 4 is provided on the top surface of the receiving seat 3, and the receiving groove 4 is used to place a circuit board 32. An interface 5 to be inspected is fixedly welded on the top surface of the circuit board 32, and the interface 5 to be inspected is electrically connected to the circuit board 32. A buffer rod 6 is installed in the receiving seat 3 for lifting and lowering. The number of the buffer rods 6 is four, and the four buffer rods 6 are distributed in the receiving seat 3 in a rectangular array, and the four buffer rods 6 all pass through the receiving seat 3. A buffer mechanism is installed on the detection base 1, and the buffer mechanism is used to cooperate and drive the buffer rod 6 to lift and lower. A stand 7 is also fixedly connected to one side of the top surface of the detection base 1, and an extrusion plate 8 is installed on one side of the stand 7 for lifting and lowering, and an extrusion needle 9 is fixedly connected to the bottom surface of the extrusion plate 8. The stand 7 is also installed with a driving member 10, and the driving member 10 is used to drive the extrusion plate 8 to lift and lower for extrusion. A detection module 11 is also fixedly installed on one side of the stand 7, a detection plug 12 is installed on the extrusion plate 8, the detection module 11 is electrically connected to the detection plug 12, the detection module 11 is electrically connected to the detection base 1, and the detection plug 12 is electrically plugged into the interface 5 to be tested.

[0029] When the circuit board 32 needs to be tested, firstly, the power supply is connected to the test base 1 to energize the test module 11. Then the circuit board 32 is pre-placed in the receiving groove 4, and then the extrusion plate 8 is driven downward by the driving member 10 to squeeze the circuit board 32 through the extrusion needle 9. The circuit board 32 then squeezes the buffer rod 6 downward. At this time, the buffer mechanism takes effect and buffers the squeezing force of the circuit board 32. While the squeezing needle 9 squeezes the circuit board 32 downward, the test plug 12 is electrically plugged into the interface to be tested 5. When the start button 2 is pressed again, the test module 11 tests the circuit board 32 and displays the test result on the test module 11. Finally, the circuit board 32 is taken out from the receiving groove 4 to complete the test of the circuit board 32.

[0030] For details, see Figure 3 and Figure 4 The buffer mechanism includes a buffer block 13 and a first spring 14. A buffer seat 15 is fixedly connected to the top surface of the detection base 1 at a position corresponding to the buffer rod 6. The number of buffer blocks 13 is the same as the number of buffer seats 15, and the buffer blocks 13 are slidably installed in the buffer seats 15. The bottom end of the buffer rod 6 passes through the buffer seat 15 and is fixedly connected to the top surface of the buffer block 13. The number of the first springs 14 is also the same as the number of the buffer seats 15. The first springs 14 are installed in the buffer seat 15, and one end of the first spring 14 is fixedly connected to the bottom surface of the buffer block 13, and the other end of the first spring 14 is fixedly connected to the inner bottom wall of the buffer seat 15.

[0031] See also Figure 4In order to facilitate positioning the buffer block 13 at the lower extrusion position or the upper extension position, the buffer seat 15 is equipped with a positioning assembly, which includes a positioning rod 16, which is installed on one side of the buffer seat 15, and the bottom end of the positioning rod 16 is hinged to the side wall of the buffer seat 15. The top of the positioning rod 16 is fixedly connected with a sliding point 17, and the outer side wall of the buffer block 13 is provided with a first sliding groove 18 and a second sliding groove 19, and the first sliding groove 18 and the second sliding groove 19 are connected at both ends, and one of the connecting ends of the first sliding groove 18 and the second sliding groove 19 is set as an upper positioning point 20, and the other connecting end of the first sliding groove 18 and the second sliding groove 19 is set as a lower positioning point 21. The sliding point 17 is slidably connected with the first sliding groove 18, the second sliding groove 19, the upper positioning point 20 and the lower positioning point 21 respectively.

[0032] When the circuit board 32 is pre-placed on the receiving seat 3, the buffer rod 6 supports the circuit board 32, and at this time, the sliding point 17 is placed in the lower positioning point 21. When the circuit board 32 is pressed downward, the circuit board 32 presses the buffer rod 6 downward, and the buffer rod 6 drives the buffer block 13 to move downward, and the buffer block 13 then presses the first spring 14 downward. The downward squeezing force of the circuit board 32 is buffered by the elastic force of the first spring 14. It should be noted that in the process of the buffer block 13 moving downward, the sliding point 17 slides from the lower positioning point 21 to the first slide groove 18, and when the squeezing of the circuit board 32 is released, the sliding point 17 slides from the first slide groove 18 to the upper positioning point 20. At this time, the circuit board 32 is accommodated in the receiving groove 4, and under the limiting action of the positioning rod 16, the circuit board 32 is positioned in the receiving groove 4, which effectively avoids the circuit board 32 from moving upward due to the reset of the first spring 14 during the detection process.

[0033] In addition, when the circuit board 32 needs to be quickly taken out of the receiving groove 4, the circuit board 32 is pressed downward again, and when the buffer block 13 moves downward again, the sliding point 17 slides from the upper positioning point 20 to the second sliding groove 19, and when the squeezing of the circuit board 32 is released, the sliding point 17 returns to the lower positioning point 21 from the second sliding groove 19. At this time, the buffer rod 6 returns to rise, thereby ejecting the circuit board 32 from the receiving groove 4, improving the convenience of taking out the circuit board 32.

[0034] It is worth noting that see Figure 4 The first slide groove 18 and the second slide groove 19 are respectively V-shaped. When the buffer rod 6 is reciprocated, the sliding point 17 is restricted to move in the direction of the first slide groove 18, the upper positioning point 20, the second slide groove 19, and the lower positioning point 21 in sequence.

[0035] See also Figure 3 and Figure 5In order to facilitate the separation of the detection plug 12 and the interface 5 to be detected after the circuit board 32 is detected, the inner wall of the accommodating seat 3 is symmetrically provided with transverse grooves 22, which are connected to the accommodating groove 4. A stopper 23 is slidably installed in the transverse groove 22.

[0036] In order to facilitate the movement of the baffle rod 23, the extrusion plate 8 is installed with an elastic member, which is a second spring 24. The second spring 24 is sleeved on the side wall of the baffle rod 23. One end of the second spring 24 is fixedly connected to the groove wall of the transverse groove 22, and the other end of the second spring 24 is fixedly connected to the side wall of the baffle rod 23.

[0037] When the blocking rod 23 is driven to move toward the circuit board 32, the blocking rod 23 presses the second spring 24, and the blocking rod 23 is blocked above the circuit board 32. When the blocking rod 23 is released, the second spring 24 releases its elastic force and drives the blocking rod 23 to return to its original position, and the blocking rod 23 is retracted into the transverse groove 22.

[0038] It is worth mentioning that see Figure 5 In order to fix the blocking rod 23 in the extended state, one end of the blocking rod 23 away from the circuit board 32 is rotatably connected to a locking stud 25, and the locking stud 25 is threadedly connected to the side wall of the accommodating seat 3.

[0039] When it is necessary to release the connection between the detection plug 12 and the interface to be detected 5, the blocking rod 23 is pushed toward the circuit board 32 through the locking stud 25, and then the locking stud 25 is screwed and tightened. At this time, the blocking rod 23 is fixed at the current extended position and restricts the upper part of the circuit board 32. When the extrusion plate 8 continues to rise, the detection plug 12 and the interface to be detected 5 are separated from each other due to the restriction of the blocking rod 23. After the detection plug 12 and the interface to be detected 5 are separated from each other, the locking stud 25 is released again. At this time, the blocking rod 23 releases the restriction on the circuit board 32, and the buffer rod 6 lifts the circuit board 32, which is convenient for taking the circuit board 32 out of the accommodating groove 4.

[0040] See also Figure 6 Due to different circuit boards 32, the positions of the interfaces 5 to be tested are different. To improve the application range of the detection device, the extrusion plate 8 includes an inner plate 26 and an outer plate 27, and the inner plate 26 is installed in the outer plate 27. The top surfaces of the inner plate 26 and the outer plate 27 are fixedly connected with a connecting frame 31, and the driving end of the driving member 10 is fixedly connected to the top surface of the connecting frame 31. The inner plate 26 and the outer plate 27 enclose an annular hole 28, and the detection plug 12 is slidably installed in the annular hole 28.

[0041] See also Figure 6In order to facilitate fixing the detection plug 12 at any position in the annular hole 28, the extrusion plate 8 is installed with a fixing assembly, which includes a bolt 30. The side wall fixing ring of the detection plug 12 is provided with a fixing ear 29. The bolt 30 passes through the fixing ear 29 and is pressed against the top surface of the extrusion plate 8.

[0042] When the position of the detection plug 12 needs to be adjusted, the bolt 30 is loosened, and then the detection plug 12 is driven to slide along the annular hole 28 to the desired position, and when the position of the detection plug 12 is confirmed, the bolt 30 is threadedly tightened, and at this time, the bolt 30 is pressed against the top surface of the extrusion plate 8, and the detection plug 12 is fixed at the current position. Among them, the wire between the detection module 11 and the detection plug 12 has enough length for the position adjustment of the detection plug 12.

[0043] It should be noted that, in this embodiment, the driving member 10 is a quick clamp in this field, and the detection module 11 is a circuit detection board in this field. If the circuit of the detected circuit board 32 is conductive, the detection module 11 displays the word "normal"; if the circuit of the detected circuit board 32 is broken, the detection module 11 displays the word "abnormal".

[0044] Working principle of a semi-automatic circuit board detection device: When the circuit board 32 needs to be tested, firstly, the power supply is connected to the testing base 1 to power on the testing module 11. Then the circuit board 32 is pre-placed in the receiving groove 4, and then the driving member 10 drives the squeezing plate 8 to squeeze downward, and the squeezing plate 8 squeezes the circuit board 32 through the squeezing needle 9, and the circuit board 32 then squeezes the buffer rod 6 downward, and the buffer rod 6 drives the buffer block 13 to move downward, and the buffer block 13 then squeezes the first spring 14 downward. The downward squeezing force of the circuit board 32 is buffered by the elastic force of the first spring 14, so that the testing plug 12 is stably and electrically plugged into the interface to be tested 5. Then, the start button 2 is pressed, and the testing module 11 detects the circuit board 32 at this time, and the test result is displayed on the testing module 11.

[0045] It should be noted that during the downward movement of the buffer block 13, the sliding point 17 slides from the lower positioning point 21 to the first sliding groove 18, and when the squeezing of the circuit board 32 is released, the sliding point 17 slides from the first sliding groove 18 to the upper positioning point 20. At this time, the circuit board 32 is accommodated in the accommodating groove 4, and under the limiting action of the positioning rod 16, the circuit board 32 is positioned in the accommodating groove 4, effectively avoiding the circuit board 32 from moving upward due to the resetting of the first spring 14 during the detection process.

[0046] When the circuit board 32 needs to be taken out, the blocking rod 23 is first pushed toward the circuit board 32 by the locking stud 25, and then the locking stud 25 is screwed and tightened. At this time, the blocking rod 23 is fixed at the current extended position and restricts the upper part of the circuit board 32. When the extrusion plate 8 continues to rise, the detection plug 12 and the interface to be tested 5 are separated from each other due to the restriction of the blocking rod 23. After the detection plug 12 and the interface to be tested 5 are separated from each other, the locking stud 25 is released again. At this time, the blocking rod 23 releases the restriction on the circuit board 32, and the buffer rod 6 lifts the circuit board 32, so that the circuit board 32 can be taken out from the receiving groove 4.

[0047] In summary, the buffer mechanism buffers the squeezing force of the circuit board 32, prompting the detection plug 12 to be plugged into the interface 5 to be detected, which is beneficial to minimize the damage of the circuit board 32 caused by the squeezing needle 9. After the detection is completed, the circuit board 32 is ejected out of the accommodating groove 4 by the buffer mechanism, which improves the convenience of taking out the circuit board 32, and is beneficial to improving the quality and efficiency of the detection.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
