Detailed Description
In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be described in further detail with reference to specific embodiments.
As shown in fig. 1, an adjusting needle holder 100 includes,
a rotating electric machine 30 mounted on the frame 20;
a cam 40 connected to the rotating motor 30, the rotating motor 30 driving the cam 40 to rotate;
a roller 51 is pivoted on a needle seat mounting part 50 which is connected to the frame 20 in a linear motion manner, and a test probe 52 is mounted on the needle seat mounting part 50; the structure for realizing the linear motion connection comprises but is not limited to a slide rail structure, and other structures capable of limiting the linear motion can be interpreted as the linear motion connection;
the first magnet 31 mounted to the frame 20 acts on the second magnet 32 mounted to the hub mounting portion 50; under the interaction of the first magnet 31 and the second magnet 32, the roller 51 is stopped against the cam 40; thereby effecting movement of the cam 40 to reciprocate the test probe 52.
By adopting the technical scheme, the roller 51 is stopped against the cam 40 through the interaction of the first magnet 31 and the second magnet 32, so that the cam 40 rotates and drives the test probe 52 to reciprocate through the roller 51.
As shown in fig. 1, the second magnet 32 is located between the first magnet 31 and the roller 51, and the roller 51 is located between the second magnet 32 and the cam 40; the force between the first magnet 31 and the second magnet 32 is repulsive force, that is, the force between the first magnet 31 and the second magnet 32 is a tendency to move the second magnet 32 away from the first magnet 31, and the roller 51 is stopped against the cam 40 because the roller 51 is located between the second magnet 32 and the cam 40. In the technical scheme, the mutual position relations among the first magnet 31, the second magnet 32, the roller 51 and the cam 40 do not need to be limited to be sequentially arranged along the same straight line, and because the rack 20 is connected with the needle seat mounting part 50 in a linear motion manner, the position adjusting requirement can be met even if the first magnet 31, the second magnet 32, the roller 51 and the cam 40 are not arranged along the same straight line; so long as the force of the first magnet 31 and the second magnet 32 against each other causes the roller 51 and the cam 40 to abut against each other.
Adopt above-mentioned technical scheme: the roller 51 is tightly abutted to the cam 40 through the magnetic force between the first magnet 31 and the second magnet 32, so that when the corresponding position of the cam 40 is abutted to the roller 51, the position of the needle seat mounting part 50 is stable and reliable, and finally the position of the test probe 52 is stable and reliable in motion.
As shown in fig. 1, the first magnet 31, the second magnet 32, the roller 51, and the cam 40 are sequentially disposed, and at this time, in order to stop the roller 51 against the cam 40, the first magnet 31 needs to apply a repulsive force to the second magnet 32.
As shown in fig. 2, the second magnet 32, the first magnet 31, the roller 51, and the cam 40 are sequentially disposed, and in this case, in order to stop the roller 51 against the cam 40, the first magnet 31 needs to apply an attractive force to the second magnet 32.
As shown in fig. 3, the second magnet 32, the first magnet 31, the cam 40, and the roller 51 are sequentially disposed, and at this time, in order to stop the roller 51 against the cam 40, the first magnet 31 needs to apply a repulsive force to the second magnet 32.
As shown in fig. 4, the first magnet 31, the second magnet 32, the cam 40, and the roller 51 are sequentially disposed, and in this case, in order to stop the roller 51 against the cam 40, the first magnet 31 needs to apply an attractive force to the second magnet 32.
As shown in fig. 1, 2, 3 and 4, the linear motion is that the frame 20 is connected with the needle seat mounting part 50 through a linear guide rail 60; i.e., linear movement of the needle mount mounting portion 50 relative to the housing 20 is limited by the linear guide 60.
As shown in fig. 1, 2, 3 and 4, the roller 51 is mounted at the bottom of the needle mount mounting portion 50, and the linear guide 60 is disposed at the top of the needle mount mounting portion 50; the cam 40 acts on the roller 51 at the bottom of the needle seat mounting part 50, and the linear guide rail 60 is positioned at the top of the needle seat mounting part 50, so that the needle seat mounting part 50 is stressed uniformly in the vertical direction, and the movement is more stable and reliable.
As shown in fig. 1, 2, 3 and 4, the first magnet 31, the second magnet 32, the roller 51 and the cam 40 are arranged along a direction coincident with the moving path of the needle holder mounting part 50; the hub mounting portion 50 is urged by the first magnet 31 and the cam 40 to approach the direction of the linear movement of the hub mounting portion 50, thereby increasing the sensitivity of the forced movement of the hub mounting portion 50.
As shown in fig. 1, 2, 3 and 4, a probe station includes the above-described adjustment needle holder 100.
The above is the preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention. It should be recognized that non-inventive variations and modifications to the disclosed embodiments, as understood by those skilled in the art, are intended to be included within the scope of the present invention as claimed and claimed.
