It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Example 1
An interval-adjustable LED digital display screen testing power-on device, as shown in fig. 1, includes a mounting plate 1, a supporting frame 2 fixedly disposed on the mounting plate 1, a first probe seat 3 fixedly disposed on the supporting frame 2, a second probe seat 4 capable of moving on the supporting frame 2 to approach or depart from the first probe seat 3, and an adjusting mechanism 5 fixed on the supporting frame 2 for driving the second probe seat 4 to move on the supporting frame 2;
the adjusting mechanism 5 comprises a compression spring 51 fixedly arranged on the supporting frame 2 for pushing the second probe seat 4 to move close to the first probe seat 3 and a limiting piece 52 for limiting the second probe seat 4 to move close to the first probe seat 3.
Wherein the limiting member 52 comprises a differential head fixedly arranged on the supporting frame 2 for pushing the second probe seat 4 to move away from the first probe seat 3; and a spacer placed inside the second probe holder 4 and the first probe holder 3 for restricting the second probe holder 4 from moving close to the first probe holder 3.
When in use, the differential head or the spacing plate can be selected as the limiting piece 52 to limit the second probe seat 4 to move close to the first probe seat 3 according to requirements; when the differential head is selected as the limiting piece 52, the ejector rod of the differential head is adjusted to be shortest (namely, the ejector rod of the differential head is not contacted with the second probe seat 4), and at the moment, the second probe seat 4 is close to the first probe seat 3 under the tension action of the compression spring 51; when the micro probe is matched with a product, the ejector rod of the micro head is adjusted to extend out, so that the ejector rod of the micro head is contacted with the movable support 73, the second probe seat 4 is pushed to overcome the tension of the compression spring 51 and be far away from the first probe seat 3, when the distance between the second probe seat 4 and the first probe seat 3 is adjusted to the probe arrangement interval of the display screen to be detected, the ejector rod of the micro head is kept to abut against the second probe seat 4, and then the power-on device is controlled to be contacted with the power-on pin of the display screen to be detected to carry out power-on work.
When a spacer is used as the limiting member 52, in the non-test state, the second probe holder 4 has a tendency to move toward the first probe holder 3 under the tension of the compression spring 51; when the distance between the probe bases is adjusted, the second probe base 4 is manually pulled to enable the second probe base 4 to overcome the tension of the compression spring 51 to move away from the first probe base 3, the distance between the second probe base 4 and the first probe base 3 is adjusted, after the distance is adjusted to the distance between the power connection pins of the display screen, the second probe base 4 is fixed through the spacing blocks with corresponding lengths, and then the power supply device is controlled to be in contact with the power connection pins of the display screen to be detected to perform power supply work.
It should be noted that, the length of the spacer is selected according to the required adjusted distance, and is placed between the first probe holder 3 and the second probe holder 4, and under the tension of the compression spring 51 and the action of the first probe holder 3, the spacer is in close contact with the first probe holder 3 and the second probe holder 4, so as to fix the second probe 4.
Compared with the prior art, the power-on device can adjust the distance between the two probe seats according to the distance between the power connection pin rows of the display screen to be tested, so that the power-on device is suitable for testing of various models of display screens, and is simple in structure and convenient to adjust.
In this embodiment, the supporting frame 2 is provided with a guiding mechanism 7 for supporting the second probe seat 4 to move on the supporting frame 2; the guide mechanism 7 comprises guide rails 71 symmetrically arranged on the support frame 2, sliders 72 sliding on the guide rails 71, and a movable support 73 fixedly connected with the sliders 72, and the second probe holder 4 is fixedly arranged on the movable support 73. During adjustment, the sliding block 72 translates on the guide rail 71 to drive the movable support 73 to move close to or away from the first probe base 3, so as to drive the second probe base 4 to move close to or away from the first probe base 3, thereby realizing adjustment of the probe spacing.
Example 2
Unlike the embodiment 1, as shown in fig. 2, the limiting member 52 is a differential head fixedly disposed on the supporting frame 2 for pushing the second probe holder 4 to move away from the first probe holder 3.
Example 3
Unlike embodiments 1 and 2, as shown in fig. 3, a spacer block disposed inside the second probe holder 4 and the first probe holder 3 for restricting the second probe holder 4 from moving close to the first probe holder 3.
Example 4
Unlike embodiments 1, 2 and 3, in the existing production configuration, the direction of the probe inserting and extracting end is usually downward, and the downward direction usually causes inconvenience in inserting and extracting the probe by manual operation due to space, structure and other problems, and to solve this problem, as shown in fig. 4 to 10, a rotating assembly 6 for rotatably mounting the supporting frame 2 on the mounting plate 1 is arranged between the mounting plate 1 and the supporting frame 2. The power-up device further comprises an angle positioning mechanism 8 for fixing the support frame 2 with the mounting plate 1.

The supporting member 81 is a linear elbow clip.
When the linear elbow clamp is used, the linear elbow clamp is operated, the ejector rod of the linear elbow clamp is in contact with the first contact rod 82, at the moment, the support frame 2 has a downward moving trend along with the positioning pressing rod 812, meanwhile, the second contact rod 84 has an upward moving trend along with the support frame 2, and when the second contact rod 84 is in contact with the stop block 83, the support frame 2 is positioned under the combined action of the linear elbow clamp, the first contact rod 82, the second contact rod 84 and the stop block 83;
when the probe needs to be changed, during the use, the straight line elbow is pressed from both sides to the operation for the ejector pin that the straight line elbow pressed from both sides breaks away from first feeler lever 82, thereby release support frame 2, make support frame 2 can rotate on mounting panel 1, at this moment, can manually rotate support frame 2, make support frame 2 slope, when adjusting support frame 2 rotation to the position that is suitable for the plug probe, change the probe, thereby make things convenient for the probe to change.
It should be noted that the probes of the first probe holder 3 and the second probe holder 4 can be removed from the probe holders for replacement.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
