[0002] Radio frequency (RF) connectors are widely used in communications, aerospace, and other fields, and their manufacturing quality directly affects signal transmission performance. Currently, the crimping process for RF connectors is mostly carried out manually or with semi-automated equipment, resulting in low production efficiency and poor consistency. With the development of 5G communication and IoT technologies, the demand for RF connectors has surged, and traditional crimping methods can no longer meet the requirements for efficient and high-precision production.
[0003] In existing technologies, RF connector crimping mainly employs two methods: First, manual crimping tools, where operators manually adjust the crimping height and perform single-cavity crimping. This method is inefficient and relies heavily on operator experience. Second, semi-automatic crimping machines, which achieve single-cavity crimping through simple mechanical structures, but face difficulties in adjusting the crimping height and cannot crimp multiple cavities simultaneously. Both methods suffer from uneven crimping force and inaccurate height adjustment, resulting in low product yield.
[0004] Therefore, how to design an automatic multi-cavity crimping machine for RF connectors that can flexibly adjust the crimping height and ensure the quality of multi-cavity crimping is a technical problem that urgently needs to be solved. Utility Model Content

[0030] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.
[0031] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0032] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0033] See Figure 1 and Figure 2 This application discloses an automatic multi-cavity crimping machine for radio frequency connectors, which includes a support base 10, a drive component 20, a placement stage 30, and a crimping component 40. The support base 10 supports the entire device, the drive component 20 provides power, the placement stage 30 places the lower crimping die (not shown in the figure), and the crimping component 40 can adjust its height and fix the upper crimping die (not shown in the figure) to perform the crimping action, thereby achieving the effect of flexibly adjusting the crimping height and ensuring the quality of multi-cavity crimping.
[0034] The support base 10 includes a base plate 11, side plates 12, and a top plate 13. The base plate 11 and the top plate 13 are arranged opposite to each other, and the side plates 12 are arranged around the base plate 11 and the top plate 13 to form an open accommodating space 14 with side openings. The side plates 12 are vertically fixed to the edges of the base plate 11 and the top plate 13 by welding or bolting.
[0035] The drive assembly 20 is a cylinder assembly, mounted on the top plate 13, with one end, the telescopic end 21 (i.e., the telescopic rod), penetrating the top plate 13 and located in the accommodating space 14. This telescopic movement drives the pressing assembly 40 to perform a pressing action. It should be noted that in this embodiment, the telescopic length of the cylinder assembly is fixed.
[0036] The placement platform 30 is mounted on the base plate 11 and located within the accommodating space 14, and is used to place the lower crimping mold. The placement platform 30 is a square platform, fixed to the base plate 11 by bolts, and its surface is polished to ensure flatness for better placement of the lower crimping mold. It should be noted that the upper and lower crimping molds are a matching set, used in actual use for replacement based on the type of connector.
[0037] The pressing assembly 40 is located in the accommodating space 14 and includes a height adjusting member 41 and a pressing member 42. One end of the height adjusting member 41 is screwed into the telescopic end 21, and the corresponding telescopic end 21 is provided with an accommodating hole for the height adjusting member 41 to be screwed. The other end is connected to the pressing member 42. A pressing upper mold is detachably fixed on the end face of the pressing member 42 away from the height adjusting member 41.
[0038] One end of the height adjustment component 41 is a screw with external threads, and the receiving hole of the telescopic end 21 is provided with a matching internal thread. The height can be adjusted by rotating the screw. Thus, the height adjustment component 41 can be rotated to adjust the height of the pressing component 42 relative to the placement platform 30.
[0039] The pressing part 42 is as follows Figure 2 The medium block structure has the upper pressing die fixed to the lower pressing member 42 by bolts or magnetic attraction. When the lower pressing member 42 is raised, the lower pressing die can be placed and removed more easily. When the lower pressing member 42 is lowered, the lower pressing member 42 is driven by the drive component 20 to push the upper pressing die down to the lower pressing die, thereby completing the multi-cavity crimping of the RF connector.
[0040] Furthermore, this equipment also includes a limiting component 50, located in the accommodating space 14 and disposed on the placement platform 30. The limiting component 50 includes a first limiting member 51, a second limiting member 52, and a third limiting member 53. The first limiting member 51 and the second limiting member 52 are disposed opposite each other on both sides of the placement platform 30, preventing displacement of the lower pressing die in the left-right direction. The third limiting member 53 is located at one end of the first limiting member 51 and the second limiting member 52, forming a second accommodating space 14 with the first limiting member 51 and the second limiting member 52 to accommodate the lower pressing die. This restricts the position of the lower pressing die at that end, preventing it from moving back and forth, thus ensuring the lower pressing die is accurately placed in the designated position and guaranteeing the accuracy and stability of subsequent pressing operations. The external structure of the first limiting member 51, the second limiting member 52, and the third limiting member 53 can be described as follows: Figure 2 As shown, it can precisely limit the position of the lower die during pressing, prevent displacement during the pressing process, and ensure the accuracy of pressing.
[0041] Furthermore, the limiting component 50 also includes a fourth limiting member 54, located on the end face of the pressing member 42 away from the placement table 30, and two of them are arranged opposite each other. A sliding groove 541 is provided between the two fourth limiting members 54. A groove 411 is provided on the end of the height adjusting member 41 away from the telescopic end 21. The height adjusting member 41 slides into the sliding groove 541 through the groove 411 to connect with the pressing member 42. This allows for convenient installation and disassembly of the height adjusting member 41 and the pressing member 42, and facilitates the replacement of the pressing mold to meet the processing requirements of different connector types.
[0042] Among them, the two fourth limiting members 54 can fix the pressing member 42 by screws or welding. The distance and appearance structure between the two fourth limiting members 54 are adapted to the height adjustment member 41, so as to ensure the connection stability of the two and allow a certain amount of sliding, which is convenient for fine adjustment of the position of the pressing member 42.
[0043] Furthermore, the crimping assembly 40 also includes a guide 43, which is vertically disposed on the placement platform 30 and located within the accommodating space 14, for the lower pressing member 42 to pass through, and the lower pressing member 42 is provided with a through hole 421.
[0044] The guide member 43 can be a cylindrical guide post, fixed to the placement platform 30 by a base. The surface of the guide post is smooth, and the material can be hard alloy to ensure wear resistance. The through hole 421 on the pressing member 42 cooperates with the guide post, so that when the pressing member 42 is pressed down, it moves linearly along the guide post, improving the pressing accuracy. In this embodiment, there are two guide members 43, located at both ends of the pressing member 42, and the corresponding pressing member 42 is provided with two through holes 421, which can better ensure the smooth movement of the pressing member 42.
[0045] Furthermore, the device also includes a fastener 60, which is disposed on the base plate 11 for fixing the display of the electrical connection drive assembly 20.
[0046] The fastener 60 can be a bracket with a slot, through which the display is secured. The display can show the real-time operating status and crimping pressure of the drive component 20, facilitating monitoring by the operator.
[0047] Furthermore, the device also includes a safety sensor 70 and an activation element 80. The safety sensor 70 is located on the open end of the base plate 11, and multiple sensors are configured, such as... Figure 1 As shown, in this embodiment, four safety sensing elements 70 and two activation elements 80 are provided, located at the two ends of the base plate 11 respectively.
[0048] The safety sensing component 70 can be an infrared sensor or a laser sensor. When a person or object approaches the dangerous area of the equipment, the sensor can detect it in time and send a signal to stop the equipment operation, ensuring the safety of the operator. The activation component 80 is a push-button switch. Only when both buttons are pressed simultaneously can the drive component 20 be triggered to drive the pressing component 42 to perform a pressing action, preventing the operator from being injured due to misoperation.
[0049] The implementation principle of this embodiment is as follows: This automatic multi-cavity crimping machine for RF connectors provides a stable support structure through the support base 10, the drive component 20 provides the power source, and the placement stage 30 and crimping component 40 realize the crimping operation of the RF connector. The height adjustment component 41 can flexibly adjust the height of the lower crimping component 42 to adapt to different crimping requirements. The limiting component 50 guides the accurate placement of the lower crimping die, the guide component 43 improves the movement accuracy of the lower crimping component 42, the fixing component 60 facilitates the installation of a display for parameter monitoring, and the safety sensing component 70 and the starting component 80 ensure the safety of the operator. Compared with the prior art, it greatly improves production efficiency and crimping quality, reduces the labor intensity of operators, and solves the problems of uneven crimping force and inaccurate height adjustment in traditional crimping methods.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
