Description

Technical Field

[0001] The utility model relates to the technical field of testing machines, in particular to a circuit board testing mechanism. Background Art

[0002] In electronic devices, circuit boards carry the important tasks of current transmission and signal transmission. By gradually increasing the voltage and observing whether the circuit fails, it can be determined whether the circuit board can operate stably under normal operating voltage to avoid damage or performance degradation caused by excessive voltage. Voltage testing helps to discover potential problems in circuit board design or manufacturing. For example, if there are certain components or unreasonable wiring on the circuit board, it may cause local voltage to be too high or too low, which in turn causes performance problems or safety hazards. Through voltage testing, these problems can be discovered and repaired in time to ensure the reliability and safety of the circuit board. Therefore, voltage testing is also a key link in circuit board quality control. During the production process, due to the influence of process, materials and other factors, there may be certain differences in the performance of the circuit board. Through voltage testing, circuit boards can be screened and classified to ensure that only circuit boards that meet the requirements can enter the next process or be delivered to customers.

[0003] In order to better test the voltage of the circuit board, a corresponding test voltage mechanism is usually used. At present, during the test process, the circuit board is basically placed directly on the surface of the test bench for testing. However, the direct placement method does not fix the circuit board well. The circuit board is easy to slide during the test, which can easily affect the test results. Moreover, during the test process, the user basically lowers his head to test, and long-term work can easily cause physical fatigue. The user cannot change the height and angle of the circuit board by other means to meet his own testing habits, resulting in low work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-5 As shown, the utility model provides a circuit board testing mechanism, which is mainly used to test the voltage of the circuit board. Before the test, the user can adjust the height and angle of the circuit board according to his own usage habits. At the same time, the circuit board to be tested can be quickly placed and fixed by the rotating seats 7 on both sides. Its specific structure mainly includes a testing table 1, all position and direction adjustments, and the position of placing the circuit board are arranged on the surface of the testing table 1. A supporting and fixed frame can also be connected to the bottom of the testing table 1 to increase the height of the testing table 1 for easy operation, and a slider 2 that moves forward and backward is provided on the surface of the testing table 1, and the slider 2 is mainly used to adjust the front and rear position of the circuit board.

[0023] In order to better connect the inspection platform 1 with the slider 2, the surface of the inspection platform 1 is equipped with two first linear guides 15 for guiding the movement of the slider 2. The surface of the inspection platform 1 is also equipped with a first pushing cylinder 16 that is connected and pushes and pulls the slider 2 to move on the first linear guides 15. The two first linear guides 15 are distributed and fixed on both sides in the front and back directions. The slider 2 slides back and forth under the guidance of the first linear guides 15, and the first pushing cylinder 16 connected to the middle part of the rear end of the slider 2 provides power to push and pull the slider 2. The position of the slider 2 moving forward and backward is changed by the extension and contraction degree of the first pushing cylinder 16.

[0024] The surface of the slider 2 is provided with a first column 3 fixed on one side and a second column 4 arranged on the other side and moving toward the first column 3. The first column 3 and the second column 4 are both composed of a base 5 and an insertion rod 6 whose top height can be adjusted after being inserted into the base 5. The first column 3 and the second column 4 are both connected with a rotating seat 7 arranged at one end of the insertion rod 6. The two rotating seats 7 are arranged opposite to each other, and the distance between the second column 4 and the first column 3 is adjustable, which can meet the needs of placing and fixing circuit boards of different lengths. However, the first column 3 and the second column 4 can change their own heights by the position of their own insertion rods 6 in the base 5, that is, the height at which the circuit board is fixed can be changed by this adjustable structure. At the same time, the circuit board is clamped and fixed between the two relative rotating seats 7. After the rotating seat 7 is connected to the insertion rods 6 on both sides, it can realize multiple angles of rotation. The user can adjust the angle at which the circuit board is fixed by rotating the rotating seats 7 on both sides. The flexible adjustment in height and angle can meet the needs of users with different usage habits, and has better flexibility.

[0025] Similarly, in order to better connect the slider 2 with the second column 4, the surface of the slider 2 is equipped with a second linear guide 17 for guiding the movement of the base 5 of the second column 4. The surface of the slider 2 is also equipped with a second pushing cylinder 18 that is connected and pushes and pulls to control the movement of one end of the base 5 of the second column 4 on the first linear guide 15. The second linear guides 17 are distributed on the surface of the slider 2 in the left and right directions. The second column 4 slides left and right under the guidance of the second linear guides 17, and the second pushing cylinder 18 connected to one side of the second column 4 provides the power for pushing and pulling. The distance between the first column 3 and the second column 4 is changed by the extension and contraction degree of the second pushing cylinder 18, thereby adjusting the placement of circuit boards of different lengths.

[0026] The structure of the first column 3 and the second column 4 is mainly composed of a base 5 and an insertion rod 6, and the height of the insertion rod 6 is adjustable. Four raised bosses 19 are provided on the side of the insertion rod 6, and a central groove 20 for inserting the insertion rod 6 and an auxiliary groove 21 for synchronously inserting the boss 19 are provided on the top of the base 5. A plurality of limit grooves 22 for limiting and fixing the boss 19 after rotating the insertion rod 6 are provided on the side of the auxiliary groove 21. When adjusting the height of the insertion rod 6, the first column 3 and the second column 4 need to be adjusted at the same time to ensure that the two ends are horizontally aligned. The insertion rod 6 rises and falls and slides in the central groove 20, and the boss 19 rises and falls and slides in the auxiliary groove 21. When the insertion rod 6 is slid and adjusted to the specified height, the user only needs to rotate the insertion rod 6 to synchronously drive the boss 19 to be fixed in the specified limit groove 22. The boss 19 is fixed in the limit grooves 22 at different heights, and the insertion rod 6 forms a structure of different heights, thereby adjusting the height at which the circuit board is fixed.

[0027] Both insertion rods 6 are inserted with locking screws 23 for adjusting and locking the corresponding rotating seats 7. After the rotating seats 7 on both sides are placed and fixed with the circuit board, the circuit board will be placed and clamped, which will generate a force that makes the rotating seat 7 squeeze one end of the insertion rod 6. The rotating seat 7 can be flipped back and forth, and the circuit board can be adjusted to different angles for easy detection, and finally locked by turning the locking screws 23 from the outside.

[0028] A card slot 8 with an L-shaped cross section and a card block 9 sealed in the card slot 8 are provided on the opposite side of the rotating seat 7. A magnetic block 10 for magnetic fixation is provided at the connection between the card slot 8 and the card block 9. Circuit board placement grooves 11 for placing circuit boards at the same time are provided in the card slots 8 on both sides. After the card block 9 is connected in the card slot 8, the circuit board to be tested placed in the circuit board placement groove 10 is clamped. The position where the card block 9 is connected to the rotating seat 7 is connected by a magnetic block 10 with a strong magnetic effect, which is convenient for assembly and disassembly, and no additional fixing components are required, saving more time when replacing the circuit board.

[0029] Two limit screws 12 are installed in the circuit board placement groove 11, and four adjustment holes 24 for inserting the limit screws 12 are provided in the circuit board placement groove 11. In order to meet the use of circuit boards of different widths, the limit screws 12 can be fixed in different adjustment holes 24 respectively to change the width of the clamping position of the circuit board. After all convenient operating positions and angles are fixed, when replacing the line board, you only need to remove the clamping block 9 to replace the circuit board clamped in the circuit board placement groove 11, and there is no need to readjust the position and angle, which has good flexibility.

[0030] The testing table 1 is also provided with a voltage test meter 13, which is connected to two voltage detection terminals 14 for detecting the voltage of the circuit board. After the circuit board is assembled with components, the user can contact the two voltage test terminals 14 of the voltage test meter 13 with different positions of the circuit board respectively. At this time, the voltage value is directly displayed on the voltage test meter, which is convenient for the user to check.

[0031] Compared with the traditional technology, before detecting the voltage of the circuit board, the user can adjust the position and angle of the circuit board according to his own working habits through the slider 2, two columns and the rotating seat 7, and can quickly replace and position the circuit board by removing the card block 9, so that the circuit board is always fixed in the specified position, thereby improving the efficiency of circuit board testing.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
