Because the probe's diameter is relatively small, typically less than 0.6mm, traditional machining equipment struggles to form the contact point in a single step for even smaller probes, such as 0.3mm probes. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a probe processing jig.

[0004] In order to achieve the above objectives, the technical solutions adopted by the present invention include:

[0005] A base, wherein a forming hole coaxial with the axis and penetrating therethrough is formed on the base, and at least one set of accommodating grooves communicating with the forming hole is formed on a side of the base;

[0006] A pushing piece having a relative tip portion and an extrusion portion, wherein the pushing piece is arranged in the accommodating groove through an elastic piece, and by means of the elastic force of the elastic piece, the extrusion portion moves toward a stationary position away from the forming hole, so that: the extrusion portion extends out of the side of the base and the tip portion does not enter the forming hole.

[0007] The present application pushes the pushing piece so that the tip of the pushing piece enters the forming hole to contact and squeeze the outer side surface of the probe. The probe is squeezed by the tip of the pushing piece and deformed to form a needle-locking point. After the needle-locking point is formed, the pressure on the pushing piece is released. Under the action of the elastic piece, the tip of the pushing piece withdraws from the forming hole, and the probe with the needle-locking point formed can be taken out, thereby realizing the one-time molding of the needle-locking point of the probe. It has the characteristics of simple structure and convenient operation.

[0008] In the preferred technical solution of the above-mentioned probe processing fixture, it also includes a force applying member arranged outside the base, which can push the pushing member in the static position toward the axis of the base, so that the tip portion enters the forming hole to squeeze the side of the probe.

The force applying member is rotated so that: the extrusion portion located in the static position is squeezed by the arc-shaped groove and moves toward the axis direction of the base, so that the tip portion extends into the forming hole.

[0010] In the preferred technical solution of the above-mentioned probe processing jig, the force applying member is a first pushing cylinder.

[0011] In a preferred technical solution of the above-mentioned probe processing jig, a handle portion is formed on the outer side surface of the force applying member.

[0012] In the preferred technical solution of the above-mentioned probe processing fixture, it also includes a base for placing the base and the force applying member, the base extends in the axial direction to form a bearing portion, and a limiting hole is formed on the bearing portion that is coaxial with the base forming hole.

[0015] In a preferred technical solution of the above-mentioned probe processing jig, the base is fixed to the bearing portion of the base by bolts.

[0016] In the preferred technical solution of the above-mentioned probe processing jig, the extrusion portion of the pushing member is a smooth and continuous curved surface structure.

[0017] The beneficial effect of the present invention is that the handle is controlled to rotate by the second pushing cylinder, so that the force applying part is rotated, and the extrusion part moves from the deepest part of the arc groove to the opening of the arc groove, so that the tip enters the forming hole to squeeze the side surface of the probe, so that the squeezed part of the side surface of the probe forms a corresponding needle point.

[0030] Example 1:

[0031] like Figures 1 to 8As shown, the probe processing fixture of the present invention includes: a base 1, a forming hole 11 coaxial with the axis and passing through the base 1 is formed on the base 1, and at least one group of accommodating grooves 12 connected to the forming hole 11 is formed on the side of the base 1; a pushing member 2, the pushing member 2 has a relative tip portion 21 and an extrusion portion 22, and the pushing member 2 is arranged in the accommodating groove 12 through the elastic member 3. With the help of the elastic force of the elastic member 3, the extrusion portion 22 moves toward the direction away from the forming hole 11 to a static position, so that: the extrusion portion 22 extends out of the side of the base 1 and the tip portion 21 does not enter the forming hole 11.

[0032] See also Figure 5 The accommodating groove 12 is perpendicular to the central axis of the base 1, the forming hole 11 is coaxial with the central axis of the base 1, the forming hole 11 is vertically arranged through the base 1, one end of the accommodating groove 12 is connected to the forming hole 11, and the other end passes through the side of the base 1. The cross section of the accommodating groove 12 is roughly "T"-shaped.

[0033] See also Figure 1 、 Figure 5 、 Figure 6 In the initial state, under the action of the elastic member 3, the extrusion portion 22 extends out of the side of the base 1, and the tip 21 does not extend into the forming hole 11. When it is necessary to make a needle point for the probe, first place the probe into the forming hole 11, then push the pushing member 2 toward the central axis of the base 1, so that the pushing member 2 overcomes the elastic force of the elastic member 3, so that the tip 21 of the pushing member 2 enters the forming hole 11 to contact and squeeze the outer side of the probe. The probe is squeezed by the tip 21 of the pushing member 2 and deformed to form a needle point. After the needle point is formed, the pressure on the pushing member 2 is released, and under the action of the elastic member 3, the tip 21 of the pushing member 2 withdraws from the forming hole 11, and then the probe with the needle point formed can be taken out. It has the characteristics of simple structure, convenient operation, and is practical.

[0034] In one or more embodiments, the elastic member 3 is a spring or elastic steel.

[0035] In one or more embodiments, a force applying member 4 is further included that is arranged on the outside of the base 1. The force applying member 4 can push the pushing member 2 in the static position toward the axial direction of the base 1 so that the tip portion 21 enters the forming hole 11 to squeeze the side of the probe; the force applying member 4 is a circular ring, and the outer circumference of the base 1 is adapted to the inner side surface of the force applying member 4. The inner side surface of the force applying member 4 is formed with an arc-shaped groove 41 that gradually moves away from the axis. The force applying member 4 is rotated so that: the extrusion portion 22 in the static position is squeezed by the arc-shaped groove 41 and moves toward the axial direction of the base 1, so that the tip portion 21 extends into the forming hole 11.

[0036] See also Figure 1 、 Figure 5 、 Figure 6 、 Figure 7When the force applying member 4 is a circular ring, the circular ring is coaxially arranged with the base 1, and an eccentrically arranged arc-shaped groove 41 is formed on the inner side of the circular ring. The deepest part of the arc-shaped groove 41 is relatively far away from the central axis of the base 1, and the opening of the arc-shaped groove 41 is the inner side of the circular ring.

[0037] In the initial state, under the action of the elastic member 3, the extrusion portion 22 of the push member 2 is located at the deepest part of the arc-shaped groove 41. When the needle point of the probe needs to be formed, the probe is first placed in the forming hole 11, and then the ring is rotated to move the extrusion portion 22 of the push member 2 from the deepest part of the arc-shaped groove 41 to the opening of the arc-shaped groove 41, and then the extrusion portion 22 of the push member 2 is squeezed and moves toward the central axis of the base 1, so that the tip 21 enters the forming hole 11 to squeeze the side surface of the probe, so that the squeezed part of the side surface of the probe forms a corresponding needle point. In this way, multiple push members 2 can be controlled to perform synchronous pushing operations, reducing the problem of extrusion deformation of thinner probes.

[0038] In one or more embodiments, a handle portion 42 is formed on the outer side of the force applying member 4. Figure 2 By configuring the handle portion 42, it is possible to facilitate the rotation of the ring-shaped force applying member 4, thereby accelerating the needle point forming efficiency of the probe.

[0039] In one or more embodiments, a base 5 is further included for placing the base 1 and the force applying member 4. The base 5 extends in the axial direction to form a bearing portion 51. A limiting hole 52 is formed on the bearing portion 51, which is coaxial with the forming hole 11 of the base 1. The base 1 is fixed to the bearing portion 51 of the base 5 by bolts.

[0040] See also Figure 4 、 Figure 5 By extending the base 5 in the axial direction to form a bearing portion 51, after the probe is placed into the base 5 through the forming hole 11 and the limiting hole 52, the portion of the probe located in the forming hole 11 is the position where the needle point is formed. Through this setting, the adjustment of the probe position can be reduced, and the efficiency of the probe needle point forming can be further accelerated.

[0041] In one or more embodiments, the base 5 is configured on a workbench 6, which is hinged with a second pushing cylinder 7. The extended shaft end of the second pushing cylinder 7 is hinged to the handle portion 42 of the force applying member 4 to push the force applying member 4 to rotate relative to the base 1.

[0042] See also Figure 8The bottom end of the second pushing cylinder 7 is hinged on the workbench 6, and the extended shaft end of the second pushing cylinder 7 is hinged on the handle portion 42. The second pushing cylinder 7 controls the handle portion 42 to rotate, and then the force applying member 4 in the form of a circular ring can rotate, so that the extrusion portion 22 moves from the deepest part of the arc-shaped groove 41 to the opening of the arc-shaped groove 41, and then the tip portion 21 enters the forming hole 11 to extrude the side surface of the probe, thereby realizing the forming of the needle point on the side surface of the probe.

[0043] In one or more embodiments, a stopper 8 for stopping the rotation position of the handle portion 42 is disposed on the workbench 6 .

[0044] See also Figure 8 The stopper 8 can limit the position of the handle portion 42, thereby preventing the handle portion 42 from rotating excessively and causing the tip portion 21 to extend too much into the forming hole 11, resulting in the probe being excessively squeezed and damaged.

[0045] In one or more embodiments, the extrusion portion 22 of the push member 2 is a smooth and continuous curved surface structure. Figure 3 Through this arrangement, the extrusion portion 22 of the pushing member 2 can be easily moved in the arc-shaped groove 41, thereby improving the smoothness of the movement of the pushing member 2 in the accommodating groove 12.

[0046] Example 2:

[0047] As the second embodiment of the present invention, the components identical or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment, and only the differences between the second embodiment and the first embodiment are described below.

[0048] The difference between Example 2 and Example 1 lies in the different force applying member 4. In Example 2, the force applying member 4 is a first push cylinder. The extended shaft end of the first push cylinder can push the pushing member 2 toward the molded hole 11 of the base 1, so that the tip 21 of the pushing member 2 can squeeze the probe in the molded hole 11, forming a needle-locking point on the probe surface. This embodiment has the characteristics of simple structure and convenient operation.

[0049] Example 3:

[0050] As the second embodiment of the present invention, the components identical or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment, and only the differences between the third embodiment and the first embodiment are described below.

[0051] The difference between Example 3 and Example 1 is that: the base 1 has a square shape, the force applying member 4 is also a square structure, and a square accommodating space is formed on the inner side of the force applying member 4, which can accommodate the base 1; the inner side surface of the square accommodating space forms a first wedge-shaped surface, and the extrusion portion 22 of the push member 2 forms a second wedge-shaped surface, and the first wedge-shaped surface is adapted to the second wedge-shaped surface.

[0052] By controlling the force applying member 4 to move downward, the first wedge surface presses the second wedge surface of the pushing member 2, thereby moving the pushing member 2 toward the forming hole 11 of the base 1 to form the probe card needle point.

[0053] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
