Description

Technical Field

[0001] The invention belongs to the technical field of probe processing equipment, and in particular relates to a molding machine for a double-headed probe. Background Art

[0002] Microelectronic hardware test probe is a widely used micro connector, which has been widely used in aviation, aerospace, navigation, military industry, medical, microelectronics, optoelectronics and other fields. In the process of preparing microelectronic hardware test probe, the main processing involved is wrapping, closing, dotting, knotting and so on.

[0003] For the mouth-wrapping process, the principle is to place one end of the needle of the probe in the needle tube, and then shrink the two ends of the needle tube and press them tightly against the outside of the needle to form a solidification and complete the fixed assembly of the needle and the needle tube.

[0004] According to the inventor's production experience, since the size of the needle tube and the needle is generally small, it is difficult to form the needle using conventional processing equipment. Therefore, it is urgent to design a processing equipment to complete the probe mouth forming process by machining, thereby improving the processing efficiency and product quality of the probe. Summary of the invention

[0005] The object of the present invention is to provide a double-head probe molding machine to solve the problem that needle tubes and needles are generally small in size and difficult to mold using conventional processing equipment.

DETAILED DESCRIPTION

[0028] The following will describe the implementation methods of the present invention in detail with reference to the embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] like Figure 2 As shown, a double-headed probe molding machine of the present invention is mainly composed of the following components:

[0030] A workbench 9,

[0031] A first stopper 8, which is fixed on an edge of a workbench 9, and a limiting step 25 is designed on the inner side of the first stopper 9;

[0032] A tightening mechanism, which is located on the workbench 9;

[0033] A mold 10; a fixture hole for the fixture to pass through is provided in the mold 10, and the mold 10 is slidably disposed between the limiting step 25 and the top tightening mechanism;

[0034] A fixture is assembled in the mold 10.

[0035] like Figure 1 As shown, the probe is composed of a first needle 4, a needle tube 5 and a second needle 6. For the mouth-wrapping forming process, the principle is to place one end of the first needle 4 and the second needle 6 of the probe in the needle tube 5, and then shrink the two ends of the needle tube 5 and press them tightly on the outside of the first needle 4 and the second needle 6, thereby forming consolidation and completing the fixed assembly of the first needle 4 and the second needle 6 and the needle tube 5.

[0036] The clamp includes a first clamp 1, a second clamp 2 and a third clamp 3; a blind hole matching the first needle 4 is arranged in the first clamp 1, a first through hole matching the needle tube 5 is arranged in the second clamp 2, a second through hole matching the second needle 6 is arranged in the third clamp 4, and one end of the blind hole and both ends of the second through hole are designed as tapered holes 7.

[0037] Specifically, the first needle 4 is first installed in the blind hole in the first fixture 1, and after placing a spring in the needle tube 5, the needle tube 5 is installed in the first through hole in the second fixture 2, and the second needle shaft 6 is installed in the second through hole of the third fixture 3. It should be noted that the first needle 4, needle tube 5 and second needle 6 are respectively tightly installed in the first fixture 1, the second fixture 2 and the third fixture 3, but only by applying force to the first needle 4, needle tube 5 and second needle 6, all three can slide out of the first fixture 1, the second fixture 2 and the third fixture 3 respectively.

[0038] When the various components of the probe are formed, the mold 10 equipped with the first clamp 1, the second clamp 2 and the third clamp 3 is first moved to the tightening mechanism, and then the tightening mechanism is used to tighten the second needle 6. As the tightening mechanism is tightened, one end of the first clamp 1 extends from the clamping hole of the mold 10 and abuts on the limiting step 25. Thereafter, the tightening mechanism continues to tighten and the two ends of the needle tube 5 will respectively extend into the conical holes 7 of the first needle 4 and the second needle 6. In this process, the two ends of the needle tube 5 will shrink toward the outside of the first needle 4 and the second needle 6, and press tightly on the outer walls of the two, completing the molding and fixation between the various components of the probe.

[0039] like Figure 2 As shown, in a double-head probe molding machine of the present invention, a second stopper 22 is provided at the edge of the workbench 8, and the second stopper 22 is located outside the tightening mechanism.

[0040] The second stopper 22 is used to limit the sliding of the mold 10 . When the side of the mold 10 abuts against the inner side of the second stopper 22 , the tightening mechanism can be activated to tighten the second needle 4 .

[0041] like Figure 2 As shown, in a double-head probe molding machine of the present invention, the clamping mechanism includes a pair of support blocks 17, in which a push rod 13 is slidably inserted, and a return spring 11 and a spring stopper 12 are arranged on the push rod 13, and the return spring 11 is located between the spring spring 12 and a support block 17, and the front end of the push rod 13 is connected to a push pin 24, and the rear end of the push rod 13 is transmission-coordinated with a driving mechanism. The driving mechanism includes a pin 14 arranged on a workbench 9, and a driving rod 19 is sleeved on the pin 14, and the driving rod 19 presses the rear end of the push rod 13 when rotating.

[0042] When the driving rod 19 rotates clockwise with the pin 14 as the reference, the driving push rod 13 moves forward, so that the push pin 13 extends into the mold 10 and contacts the second needle 6 to implement the push. When the driving rod 19 rotates counterclockwise with the pin 17 as the reference, the push rod 13 will quickly move backward under the elastic force of the reset spring 11 and reset in time.

[0043] like Figure 3 As shown, in a double-head probe molding machine of the present invention, a guide shaft 27 is provided on the lower side of the driving rod 19 , and a guide groove 26 is provided on the workbench 9 .

[0044] The guide shaft 17 extends into the guide groove 26, and the driving rod 19 rotates within a certain range based on the pin shaft 1 and the guide groove 26.

[0045] like Figure 2 As shown, in a double-head probe forming machine of the present invention, a front limit block 20 and a rear limit block 15 are provided on the side of the workbench 9, and the front limit block 20 and the rear limit block 15 are located on the rotation trajectory of the driving rod, and are used to limit the forward and backward movement range of the driving rod 19, wherein the rear limit block 15 is arranged on the side of the workbench 9 through a third baffle 16.

[0046] like Figure 2 As shown, in a double-head probe molding machine of the present invention, a top block 18 is provided on the side of the driving rod 19 , and the top block 18 is used to contact the rear end of the top rod 13 to smoothly transmit the power of the driving rod 19 .

[0047] like Figure 2 As shown, in a double-head probe molding machine of the present invention, a handrail 21 is provided on the side of the workbench 9. The staff can hold the handrail 21 to ensure that the workbench 9 does not shake during operation.

[0048] like Figure 2 As shown, in a double-head probe molding machine of the present invention, the bottom of the workbench 9 is supported by a plurality of supporting legs 23, which can ensure the working stability.

[0049] The above description shows and describes several preferred embodiments of the invention, but as mentioned above, it should be understood that the invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
