Technical Field

[0002] A printed circuit board, also known as a circuit board, is an essential component in electronic devices, playing a dual role of electrical and mechanical connection in electronic devices. Testing is extremely important in the production of printed circuit boards. If there are problems with the products, serious consequences will occur during future use. Detecting problems as early as possible can avoid many unnecessary losses.

[0003] Generally, a corresponding flying probe testing device is used to test the circuit board, which mainly includes two parts: flying probe control and circuit board fixation. The flying probe control is mostly controlled by a manipulator to move. When in use, the circuit board to be tested is first fixedly placed on the test table through a corresponding fixing component, and then the manipulator drives the flying probe to move, so that the flying probe continuously contacts and conducts with each point of the circuit board for testing.

[0004] However, in the existing flying probe testing devices for circuit board detection, one flying probe testing system corresponds to one test table. When one circuit board test is completed, it needs to be removed from the test table, and then the next circuit board is installed for testing. During the process of replacing the circuit board to be tested, there is a gap period in the flying probe testing system and continuous detection cannot be carried out, reducing the overall detection efficiency.

During use, the circuit board to be detected is fixed on the detection table through the fixing component, and the detection table with the circuit board is moved under the manipulator through the moving component. Then, the manipulator is started to drive the flying probe to move for detection. When detecting a circuit board, the detection table that has been detected can be driven by the moving component to move. The detected circuit board is disassembled through the fixing component and a new circuit board is installed and fixed. After the circuit board being detected is completed, the detection table is driven by the moving component to move for replacement, thereby realizing continuous detection, reducing the detection gap period, and improving the detection efficiency.

Detailed implementation manners

[0031] The following further describes the present application in conjunction with the attached Figures 1 - 3 drawings for more details.

[0032] The embodiment of the present application discloses a circuit board component detection device. Referring to Figures 1 to 3 , it includes a base 1 and a manipulator 11 arranged on the base 1. A flying probe 111 for detection is arranged on the manipulator 11. The manipulator 11 is used to drive the flying probe 111 to move. The base 1 is provided with a controller for driving the manipulator 11 to move and the flying probe 111 to perform detection. Two detection tables 2 are movably arranged on the surface of the base 1. The base 1 is provided with a moving component 3 for driving the detection table 2 to move. A detection block 4 is arranged on the detection table 2, and a fixing component 5 for fixing the circuit board is arranged on the detection block 4. The moving component 3 includes a moving motor 31, a moving gear 32 and a moving rack 33. The moving motor 31 is fixedly arranged on the side wall of the base 1. Two moving grooves 12 are arranged on the surface of the base 1 along the length direction. The bottom wall of the moving groove 12 is provided with a gear groove 121. The moving gear 32 is rotatably arranged in the gear groove 121 and is coaxially connected to the rotating shaft of the moving motor 31. The moving rack 33 is fixedly arranged on the bottom walls of the two detection tables 2 and is adapted to be inserted into the moving groove 12 and engaged with the moving gear 32. The circuit board is fixedly arranged on the detection block 4 through the fixing component 5. After one circuit board is detected, the moving motor 31 is started to drive the moving gear 32 to rotate, thereby driving the moving rack 33 to slide and drive the detection table 2 to move, so that the detected circuit board moves away from the manipulator 11. At this time, another detection table 2 moves to the lower part of the manipulator 11 for detection. At this time, the detected circuit board is disassembled and the circuit board to be detected is installed through the fixing component 5. After another circuit board is detected, the moving motor 31 is started to repeat the above operation, so as to make full use of the detection time, reduce the idle time, realize continuous detection and improve the detection efficiency.

[0033] To improve the convenience of installing and disassembling the circuit board, referring to Figure 2 and Figure 3 , the fixing component 5 includes a fixing block 51, a fixing gasket 53 and a fixing bolt 52. Two auxiliary blocks 41 are fixedly arranged on the surface of the detection block 4. Two positioning grooves 42 are arranged on the surface of the detection block 4, and the positioning grooves 42 are arranged between the two auxiliary blocks 41. A positioning block 511 is integrally and fixedly arranged on the fixing block 51, and the positioning block 511 is adaptively inserted into the positioning groove 42.

The fixing bolt 52 penetrates through the fixing block 51 and the positioning block 511, and the fixing bolt 52 is used to install the fixing block 51 on the detection block 4. When installing the circuit board, place the circuit board between the auxiliary blocks 41, limit the circuit board by abutting the auxiliary blocks 41 against the circuit board. Then, adaptively insert the positioning block 511 into the positioning groove 42, and install the fixing block 51 on the detection table 2 through the fixing bolt 52, so that the fixing gasket 53 abuts against the edge part of the circuit board surface where no circuit is provided, thus completing the fixation. When disassembling, disassemble the fixing bolt 52 and remove the fixing block 51 to disassemble the circuit board, improving the convenience of installing and disassembling the circuit board and facilitating use.

[0034] To further improve the convenience of replacing the circuit board, referring to Figure 2 and Figure 3 , two sliding rails 21 are fixedly welded on the surface of the detection table 2. The sliding rails 21 are perpendicular to the moving groove 12, and the cross-section of the sliding rails 21 is T-shaped. A T-shaped sliding groove 44 is penetrated through the side wall of the detection block 4, and the sliding groove 44 penetrates through the bottom wall of the detection block 4. The sliding rails 21 are adaptively inserted into the sliding groove 44. Installation blocks 22 are arranged at both ends of the detection table 2, and the installation blocks 22 can abut against the detection block 4. The detection table 2 is provided with installation bolts 221 for installing the installation blocks 22 on the detection table 2. The detection table 2 is provided with a locking component 6 for locking the detection block 4. When replacing the circuit board, release the lock of the detection block 4 through the locking component 6, and then slide the detection block 4 so that the detection block 4 is further away from the manipulator 11. At this time, replace the circuit board, which can reduce the possibility of interference by the manipulator 11, and further improve the convenience of replacing the circuit board.

[0035] For the stability of locking, referring to Figure 1 and Figure 3, the locking assembly 6 includes a locking rod 61, a locking block 62 and a locking spring 63. A first locking groove 43 is provided on the side wall of the detection block 4 away from the manipulator 11. The locking block 62 is slidably arranged in the first locking groove 43 in a matching manner. A plurality of locking springs 63 are provided. The locking springs 63 are arranged in the first locking groove 43 and connect the inner wall of the first locking groove 43 and the side wall of the locking block 62. Two locking rods 61 are provided. The locking rods 61 are rotatably arranged on the detection table 2 through hinges and can abut against the side wall of the detection block 4. A second locking groove 611 is provided through the side wall of the locking rod 61 close to the detection block 4. The second locking groove 611 penetrates the side wall of the locking rod 61 away from the hinge end. The locking block 62 can be inserted into the second locking groove 611 in a matching manner.

The locking rod 61 is limited by the locking block 62, and the detection block 4 is limited by the locking rod 61 to complete the locking, improving the locking stability.

[0036] The implementation principle of the circuit board assembly detection device in the embodiment of the present application is as follows: When the circuit board on one detection table 2 is completed, start the moving motor 31. The moving motor 31 drives the moving gear 32 to rotate, drives the moving rack 33 to move, and thus drives the detection table 2 to move, so that the circuit board on another detection table 2 reaches below the manipulator 11 to start detection. At this time, push the locking block 62 to compress the locking spring 63 so that the locking block 62 disengages from the second locking groove 611, rotate the locking rod 61 to release the locking of the detection block 4, slide the detection block 4 so that the detection block 4 is further away from the manipulator 11, and then release the fixation of the circuit board through the fixing assembly 5, so as to replace other circuit boards to be detected. Then push the detection block 4 to move until the detection block 4 abuts tightly against the mounting block 22, push the locking block 62 to compress the locking spring 63 and rotate the locking rod 61 to insert into the auxiliary groove 211 and abut tightly against the detection block 4, release the locking block 62, and the locking spring 63 restores to push the locking block 62 to be inserted into the second locking groove 611 to complete the locking, thus completing all operations of circuit board replacement. After the circuit board waiting for detection is completed, start the moving motor 31 and repeat the above operations. By setting two groups of detection tables 2 in the present application, the operation of circuit board replacement is completed while another circuit board is being detected, thereby reducing the idle time and realizing continuous detection, thus improving the detection efficiency.
