[0020] Beneficial Effects

[0021] The present invention provides a testing device for aging testing of electronic products. Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The test device for aging test of electronic products can automatically pick up the rectifier transmitted to the bottom of the drive cylinder mechanism through the mutual cooperation between the linear module, the drive cylinder mechanism, the on-off power test cover mechanism, the servo motor and the driving gear, and drive the rectifier to rotate in the clockwise direction. During the process of passing through the on-off power test cover mechanism, multiple rectifiers can be automatically subjected to continuous on-off power aging tests to simulate the actual working environment of the rectifier so as to test the stability of the rectifier conduction current.

[0023] (2) The test device for aging test of electronic products, through the mutual cooperation between the bearing tube, the lower protrusion, the convex ring and the clamping assembly, can automatically control the working state of the clamping assembly under the action of the lower protrusion and the convex ring during the rotation of the bearing tube. By changing the position of the ring on the outside of the clamping plate and the connecting block, the plurality of clamping plates can be quickly brought close to each other, so that the clamping assembly can automatically clamp the rectifier directly below between the plurality of clamping plates during the rotation, and rotate along the clockwise direction with the clamping assembly. The clamping operation is simple and convenient, and manual intervention is reduced. The plurality of clamping assemblies cooperate with each other to continuously clamp the rectifier delivered to the bottom of the driving tube mechanism, thereby realizing continuous testing operation. This continuous clamping and rotation process makes the entire testing process more efficient and automated, thereby improving testing efficiency.

[0024] (3) The test device for aging test of electronic products cooperates with each other through the arc cover, the current stability alarm, the on-off power test frame assembly and the first contact block. Since the front contact block, the rear contact block and the adjacent current stability alarm are electrically connected through wires, when the rectifier rotates, the two energized ends on the rectifier will contact the front contact block and the rear contact block respectively. Through the current stability alarm, it can be intuitively detected whether the current transmitted by the rectifier is stable, and the performance of the rectifier can be tested. Under the setting of multiple groups of front contacts and rear contacts, the rectifier can contact the corresponding front contacts and rear contacts in turn during the revolution, realizing multiple on-off power aging tests. At the same time, the multiple working circuits are individually controlled, which improves the test accuracy.

[0025] (4) The test device for aging test of electronic products, through the mutual cooperation between the first gear, the second gear, the third gear, the third bevel gear and the arc groove, can rotate the adjustment disk to make the second gear and the third gear rotate in the opposite direction, thereby driving the first test component, the second test component, the third test component, the fourth test component, the fifth test component and the sixth test component to move closer to or away from the first contact block at the same time, changing the spacing between adjacent test components and between the first contact block and the adjacent test components, so that the spacing between two adjacent front contact blocks in multiple test components and the spacing between the first contact block and the adjacent front contact blocks always remain the same, and the spacing between adjacent test components can be flexibly and conveniently adjusted, which can meet the aging test needs of powering on and off at different intervals, and has a wider applicability.

Through the mutual cooperation between the first gear 7521, the second gear 762, the third gear 765, the third bevel gear 7610 and the arc groove 73, the adjusting disk 767 is turned to make the second gear 762 and the third gear 765 reverse. Rotate, and then drive the first test component 752, the second test component 753, the third test component 754, the fourth test component 755, the fifth test component 756 and the sixth test component 757 to move closer to or away from the first contact block 77 at the same time, change the distance between adjacent test components and between the first contact block 77 and the adjacent test components, so that the distance between two adjacent front contact blocks 7524 in multiple test components and the distance between the first contact block 77 and the adjacent front contact blocks 7524 always remain the same, and flexibly and conveniently adjust the distance between adjacent test components to meet the aging test requirements of powering on and off at different intervals.

[0054] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0055] When in use, the rectifiers 10 to be tested are placed on the top of each placement seat 4 in turn. Since the linear module 2 belongs to the existing technology well known to those skilled in the art, the linear module 2 drives multiple linear slide blocks 3 to move intermittently in the left and right directions, and one of the rectifiers 10 is transported to the bottom of the drive cylinder mechanism 6. The linear module 2 is suspended once, and finally multiple rectifiers 10 to be tested are transported to the bottom of the drive cylinder mechanism 6 in turn. During the process, the servo motor 8 works to drive the active gear 9 to rotate, and the gear ring 63, the bearing cylinder 62 and a plurality of clamping components 67 rotate in the clockwise direction. As the bearing cylinder 62 rotates, the clamping component 67 can automatically control the clamping component under the action of the lower protrusion 65 and the protruding ring 66. In the working state of 67, when the vertical shaft 671 rotates at the bottom of the middle shaft 64, the clamping plate 675 automatically moves downward under the push of the lower protrusion 65. When the clamping plate 675 is pushed to the bottom, a plurality of clamping plates 675 are located outside the rectifier 10 directly below. Then the clamping assembly 67 continues to rotate in the clockwise direction. During the process, the connecting shaft 679 slides along the left inclined surface of the convex ring 66, and the vertical shaft 671 slides along the left inclined surface of the lower protrusion 65. The vertical shaft 671 gradually does not contact the lower protrusion 65, and the connecting shaft 679 gradually does not contact the convex ring 66. Since the bottom of the lower protrusion 65 is lower than the bottom of the convex ring 66, under the elastic action of the first spring 672 and the third spring 6710, the clamping plate 675 and the collar 678 move up at the same time, and the clamping assembly 67 is clamped. The upward movement speed of plate 675 is greater than the upward movement speed of collar 678. During the process, collar 678 slides along the plurality of clamping plates 675, overcoming the elastic force of second spring 677, so that the plurality of clamping plates 675 quickly move closer to each other, and automatically clamp the rectifier 10 directly below between the plurality of clamping plates 675, and rotates along with the clamping assembly 67 in the clockwise direction, and then the connecting shaft 679 contacts the convex ring 66 again, and the convex ring 66 pushes the connecting shaft 679 and the collar 678 toward the end away from the central axis 64, so that the collar 678 continues to slide along the outer wall of the clamping plate 675, and clamps the rectifier 10 between the plurality of clamping plates 675. The plurality of clamping assemblies 67 cooperate with each other to continuously clamp the rectifier 10 delivered to the bottom of the driving cylinder mechanism 6, and perform continuous testing operations. After the rectifier 10 transmitted to the bottom of the driving cylinder mechanism 6 is clamped up, the rectifier 10 is driven to rotate in the clockwise direction and passes through the inside of the power-on and power-off test cover mechanism 7. During the process, the rectifier 10 is automatically subjected to multiple power-on and power-off aging tests to test the stability of the conduction current of the rectifier 10. During the process of passing through the inside of the power-on and power-off test cover mechanism 7, since the front contact block 7524, the rear contact block 7526 and the adjacent current stability alarm 72 are electrically connected through wires, when the two energized ends on the rectifier 10 are in contact with the front contact block 7524 and the rear contact block 7526 respectively, the circuit is turned on with the external power supply, and the current stability alarm 72 is used to intuitively detect whether the current transmitted by the rectifier 10 is stable. If the rectifier 10 operates well,The current transmitted when the energized end contacts the contact block remains stable and fluctuates within a preset range. If there is a problem with the rectifier 10, the current transmitted when the energized end contacts the contact block will produce abnormal fluctuations or changes. At this time, the current stability alarm 72 will send out a warning signal. The performance of the rectifier 10 after multiple power on and off tests is tested. Under the setting of multiple groups of front contact blocks 7524 and rear contact blocks 7526, the rectifier 10 is in contact with the corresponding front contact blocks 7524 and rear contact blocks 7526 in turn during the revolution, completing multiple power on and off aging tests. When it is necessary to perform power on and off tests on the rectifier 10 at different intervals, it is only necessary to adjust the spacing between adjacent test components. During the process, the adjustment disk 767 is rotated to make the first The second gear 762 and the third gear 765 rotate in opposite directions, thereby driving the first test assembly 752, the second test assembly 753, the third test assembly 754, the fourth test assembly 755, the fifth test assembly 756 and the sixth test assembly 757 to move closer to or farther from the first contact block 77 at the same time, changing the spacing between adjacent test assemblies and between the first contact block 77 and the adjacent test assemblies, so that the spacing between two adjacent front contact blocks 7524 in the multiple test assemblies and the spacing between the first contact block 77 and the adjacent front contact block 7524 are always kept the same. By adjusting the spacing between adjacent test assemblies, the aging test requirements of turning on and off the rectifier 10 at different intervals can be achieved.
