Technical Field

[0001] The utility model relates to the technical field of pressure needle positioning, in particular to a pressure needle positioning device. Background Art

[0002] Pin pressing typically involves accurately installing, inserting, or connecting a slender, needle-like object to a specific location using a certain amount of pressure during a specific production or processing process. This practice is common in electronics manufacturing, mechanical assembly, and other fields. However, in large-scale production, it's crucial to ensure that the pin placement is highly consistent across every product. Using a positioning device ensures that each pin pressing operation is performed in the same location, thereby improving product quality and stability.

[0003] In the existing technology, some pin press positioning devices often need to perform pin pressing operations to achieve functions such as electrical connection. At present, the traditional pin press tooling mainly relies on the two mounting holes of the connector for mounting and locking to achieve positioning. This positioning method can meet the pin pressing needs of connectors with such mounting holes to a certain extent. However, with the continuous development of technology, the latest EMM products have changed. The new EMM product no longer has these two mounting holes, which makes it impossible for the existing pin press tooling to directly and effectively position it, which will affect the performance and reliability of the product and increase the scrap rate during production. Therefore, in response to the above shortcomings, a pin press positioning device is proposed. Utility Model Content

[0024] The top of the support plate 1 is fixedly connected to the support base 4 through a precise welding process. The support base 4 is a sturdy structure, and the internal front side of the top thereof is threadedly connected to two fixing components for locking. The external threads of the two fixing components are connected to the baffle 7, and the top of the support base 4 is in close contact with the bottom end of the baffle 7 to ensure that it will not loosen during operation. The fixing assembly includes bolts 5, and the outsides of the two bolts 5 are respectively connected to the inside of the left and right sides of the support base 4 through precise threaded fit. The top of the bolt 5 is fixedly connected to a connecting ball 6, and the surface of the connecting ball 6 is finely polished to facilitate the operator's rotation operation. The outsides of the two bolts 5 are respectively threadedly connected to the inside of the left and right sides of the baffle 7, and the baffle 7 can be firmly fixed by rotating the bolts 5;

[0025] The top of the support plate 1 is fixedly connected to a positioning shaft 8, which is a straight and high-precision cylindrical structure, and its outer bottom end is fixedly connected to the inside of one side of the support seat 4 by a firm welding method. The outer bottom end of the positioning shaft 8 is slidably connected to a tooling support column 9, which is a structure with a specific shape and size, and can provide stable support for the positioning tooling 10. The two positioning shafts 8 are externally slidably connected to a positioning tooling 10. The positioning tooling 10 has been carefully designed and processed, and has a structure that matches the positioning shaft 8 and can slide smoothly on the positioning shaft 8. The top of the positioning tooling 10 is internally slidably connected to an EMM connector 11. The EMM connector 11 is a precision electronic component that needs to be accurately positioned by the positioning tooling 10;

[0026] The top rear side of the support base 4 is fixedly connected with a buffer rod 12, which is used to provide a buffering effect during the needle pressing process, so that the movement of the device during the needle pressing is more stable. The top of the buffer rod 12 is fixedly connected with a loading plate 13, which is connected to the loading plate 13 by a stop cap. The loading plate 13 is a flat plate-like structure that can carry the pressure head 14 to move stably during the movement. The bottom end of the loading plate 13 is fixedly connected with a pressure head 14, which is a structure with a specific shape and size that can accurately press the EMM connector 11. The bottom end of the pressure head 14 contacts the top of the EMM connector 11 to ensure that pressure can be accurately applied during the needle pressing process. The top rear side of the support plate 1 is fixedly connected with a support rod 15, which is a cylindrical structure that can provide a stable guide for the movement of the loading plate 13. The rear interior of the loading plate 13 is slidably connected to the outside of the two support rods 15 to ensure that the loading plate 13 does not deviate during movement.

[0027] Reference Figure 1 、 Figure 2 and Figure 4, a receiving hole 16 is provided inside the left and right sides of the positioning tool 10. The receiving hole 16 is a space with a specific shape and size, which can accommodate components such as the sliding rod 17, the strong spring 18 and the limit plate 19. A sliding rod 17 is slidably connected to the inner wall of one side of the inner part of the positioning tool 10. The sliding rod 17 is a straight cylindrical structure with a certain strength, which can slide smoothly inside the positioning tool 10. The outer sleeve of the sliding rod 17 is provided with a strong spring 18. The strong spring 18 is a spring with a high elastic coefficient, which can provide a stable elastic force for the sliding rod 17 during operation. One end of the sliding rod 17 is fixedly connected to the limit plate 19. The limit plate 19 is a structure with a specific shape and size, which can slide smoothly inside the receiving hole 16. The outer part of the limit plate 19 is slidably connected to the inside of the receiving hole 16 to ensure that no offset occurs during operation. One end of the strong spring 18 is fixedly connected to one side of the inner portion of the accommodating hole 16, and the other end is fixedly connected to one side of the limiting plate 19, providing a stable elastic force for the limiting plate 19. One side of the limiting plate 19 is fixedly connected to an arc-shaped force block 20, which is a structure with a specific shape and size, and can be in close contact with the outside of the positioning shaft 8 and be squeezed by the positioning shaft 8. One side of the arc-shaped force block 20 is in contact with the outside of the positioning shaft 8, ensuring that the force can be accurately transmitted during operation. The other end of the sliding rod 17 is fixedly connected to an extrusion plate 21, which is a structure with a specific shape and size, and can be driven by the sliding rod 17 to squeeze and position the EMM connector 11. One side of the extrusion plate 21 is in contact with one side of the EMM connector 11, ensuring that the EMM connector 11 can be accurately positioned during operation.

[0028] Working principle: First, install the device on the hand press, and then the support plate 1 serves as the basis of the entire device. The multiple support legs 2 at its bottom end stably support the support plate 1 through the gasket 3. The support seat 4 at the top of the support plate 1 provides support for subsequent components. When it is necessary to position the EMM connector 11, put the tooling support column 9 on the bottom end of the outside of the positioning shaft 8, and then put the positioning tooling 10 on the outside of the two positioning shafts 8, and then position it. In this process, due to the extrusion of the positioning shaft 8, the arc-shaped force block 20 inside the positioning tooling 10 is squeezed, and the arc-shaped force block 20 drives the sliding rod 17 to move, and the strong spring 18 outside the sliding rod 17 is compressed. At the same time, the limit plate 19 at one end of the sliding rod 17 slides in the accommodating hole 16. As the sliding rod 17 moves, the extrusion plate 21 at the other end moves toward the inside of the EMM connector 11, completing the installation of the EMM connector 11 and the positioning tooling 10.

[0029] Then, the EMM connector 11 is placed inside the top of the positioning fixture 10. The bolt 5 connected to the front side of the top of the support base 4 and the connecting ball 6 at the top of the bolt 5 cooperate with the baffle 7 to limit and fix the positioning fixture 10. At this time, the top of the support base 4 contacts the bottom of the baffle 7.

[0030] Finally, when the EMM connector 11 needs to be pressed, the buffer rod 12 on the rear side of the top of the support plate 1 provides stable support, and the press head 14 on the bottom of the carrier plate 13 presses the EMM connector 11. The rear inner part of the carrier plate 13 slides outside the support rod 15 to ensure the stability of the carrier plate 13.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
