[0039] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0040] Figures 1 to 3 、 Figure 5 and Figure 6 A schematic structural diagram of a press-fitting tool for a radio frequency connector according to an embodiment of the present application is shown; Figure 4 FIG. 1 shows a schematic structural diagram of a radio frequency connector according to an embodiment of the present application. Figures 1 to 6 As shown, an embodiment of the present application provides a pressing tool for a radio frequency connector, comprising a mounting bracket 1, a force sensor 2, a connecting rod 3, a suction and pressure head 4, and a vacuum generator 5, one end of the force sensor 2 is connected to the mounting bracket 1, the other end of the force sensor 2 is connected to one end of the connecting rod 3, the other end of the connecting rod 3 is connected to the suction and pressure head 4 through an elastic member 6, the vacuum generator 5 is installed on one side of the mounting bracket 1, and the vacuum generator 5 is connected to the suction and pressure head 4 through an air pipe 7.

[0041] Specifically, the pressing tool can be installed at the end of a transplanting mechanism such as a manipulator through a mounting bracket 1. The force sensor 2, the connecting rod 3 and the suction and pressure head 4 are connected in sequence. The suction and pressure head 4 is used to absorb the RF connector (referred to as the connector) 20. The vacuum generator 5 is used to provide suction for the suction and pressure head 4 so that the suction and pressure head 4 adsorbs the RF connector 2, and then the RF connector 2 is transported to the position to be installed for assembly through the pressing tool.

[0042] The transplanting mechanism equipped with a pressing tool can cooperate with the automatic feeder of the RF connector 20 to realize the automatic picking and assembly of the RF connector 20, thereby improving the assembly efficiency of the RF connector 20. The automatic feeder feeds the RF connector 20 to be assembled to the material picking position, and the transplanting mechanism drives the pressing tool to move above the material picking position and aligns it with the RF connector 20 at this position. The transplanting mechanism drives the pressing tool to move down close to the RF connector 20. When the suction head 4 moves down to contact the RF connector 20, the elastic member 6 (such as a compression spring, an elastic sleeve) is compressed, which can form a buffer between the suction head 4 and the RF connector 20, ensuring that the RF connector 20 and the suction head 4 are not in hard contact, which helps to stably and quickly absorb the connector, and avoids damage to the RF connector 20 caused by hard contact between the suction head 4 and the RF connector 20; then, the vacuum generator 5 is opened, so that the suction head 4 can reliably absorb the RF connector 20; the suction head After sucking up the RF connector 20, the transfer mechanism drives the press tool to move above the connector assembly point. The transfer mechanism drives the press tool downward and applies force to the press tool through the pressing mechanism to press the RF connector 20 onto the connector assembly point. When the RF connector 20 is assembled, the force between the RF connector 20 and the connector assembly point is transmitted to the force sensor 2 through the connecting rod 3. The assembly status of the RF connector 20 during the press-fit process is monitored in real time. The downward pressure of the pressing mechanism is adjusted according to the force (the pressing mechanism acts on the mounting bracket 1, and then acts on the suction head 4 through the force sensor 2 and the connecting rod 3). This prevents the connector from being inserted incorrectly or over-pressurized, ensures that the RF connector 20 is securely assembled at the assembly point, and guarantees product quality and avoids damage to the connector. For example, when the force is large, the downward pressure can be reduced to avoid damage to the RF connector 20; when the force is small, the downward pressure can be increased to ensure that the RF connector 20 is securely assembled at the assembly point and avoid loose connector assembly. In addition, in this embodiment, the two ends of the connecting rod 3 are respectively connected to the force sensor 2 and the suction pressure head 4. While the connecting rod 3 is used to transmit the force, the length of the connecting rod 3 can be adjusted as needed, which is conducive to the assembly of materials (RF connector 20) in a narrow space.

[0043] In this embodiment, the RF connector 20 is described by taking the SMP-KK connector as an example. In specific implementation, the RF connector 20 can also be a precision connector such as an SMA (Sub-Miniature A)-KK connector and an N-KK connector. SMP is a new type of ultra-small blind-mate RF connector, which has the characteristics of high frequency of use, fast connection, strong vibration resistance, and allows a certain amount of mismatch in the axial and radial directions. It is particularly suitable for high-density blind plugging between printed circuit boards, chassis, and cabinets, and is widely used in phased array radar, aerospace, and civil communications. The SMA RF coaxial connector has the advantages of small size, wide bandwidth, excellent mechanical and electrical properties, and high reliability. It is widely used in microwave communications, aerospace navigation, weapon systems, and microwave measurement equipment. The N-type series connector is a medium to high power connector with a threaded structure. It has the characteristics of strong shock resistance, high reliability, and excellent mechanical and electrical properties. It is widely used in wireless equipment under vibration and harsh environmental conditions, as well as mobile communication indoor coverage systems and outdoor base stations. The above-mentioned KK refers to the model of the connector in the connector, which is a standard model and will not be repeated here.

[0044] The pressing tool of the RF connector provided in the embodiment of the present application is provided with a mounting bracket 1, a force sensor 2, a connecting rod 3, a suction head 4 and a vacuum generator 5. One end of the force sensor 2 is connected to the mounting bracket 1, and the other end of the force sensor 2 is connected to one end of the connecting rod 3. The other end of the connecting rod 3 is connected to the suction head 4 through an elastic member 6. The vacuum generator 5 is installed on one side of the mounting bracket 1, and the vacuum generator 5 is connected to the suction head 4 through an air pipe 7. The elastic member 6 can be used to buffer the suction head 4 when the suction head 4 absorbs the RF connector 20, so that the RF connector 20 can be absorbed stably and quickly, and the RF connector 2 can be avoided. 0 causes damage; at the same time, connecting the force sensor 2 to the mounting bracket 1, and connecting the force sensor 2, the connecting rod 3, and the suction and pressure head 4 in sequence, can accurately monitor the assembly quality of the RF connector 20 in real time during assembly, avoid false insertion or overpressure of the RF connector 20, and ensure the assembly quality of the RF connector 20; in addition, the above-mentioned pressing tool has a simple and reliable overall structure and can be quickly and conveniently installed at the end of the transplanting mechanism to achieve automated assembly of the RF connector 20, improving connector assembly efficiency while reducing the cost of the pressing tool; the length of the connecting rod 3 can be adjusted according to the connector's pressing needs, which is beneficial for assembling connectors in confined spaces and increases the applicability of the pressing tool. The vacuum generator 5 is set on one side of the mounting bracket 1 and will not affect the operation of the suction and pressure head 4. The structural layout is reasonable and compact.

[0045] In some embodiments, as Figure 2 、 Figure 5 and Figure 6As shown, the suction and pressure head 4 includes a connecting head suction chamber 41 and an installation chamber 42 for installing the air pipe 7. The connecting head suction chamber 41 is arranged at the end (tail) of the suction and pressure head 4. The connecting head suction chamber 41 and the installation chamber 42 are separated by a partition 43. The partition 43 is provided with a first vacuum air inlet 44 connected to the air pipe 7.

[0046] The vacuum generator 5 is provided with a second vacuum air inlet, which is connected to the first vacuum air inlet 44 via the air pipe 7. The vacuum generator 5 utilizes the air pipe 7 to eject compressed air at high speed, forming a jet at the outlet of the air pipe 7 (the first vacuum air inlet 44), generating an entrainment flow. Under the entrainment effect, the air around the outlet of the air pipe 7 is continuously sucked away, reducing the pressure within the connector suction chamber 41 to below atmospheric pressure, forming a certain vacuum level, and thus providing suction to achieve the adsorption and transportation of the RF connector 20. The vacuum generator 5 has a simple structure, small size, light weight, low price, and easy installation. It also quickly creates and releases a vacuum, making it suitable for distributed and intermittent use.

[0047] In this embodiment, the inner cavity of the suction head 4 is divided into a connector suction chamber 41 and an installation chamber 42 along its axial direction by a partition 43, and a first vacuum air inlet 44 for connecting to the air pipe 7 is provided on the partition 43. The compressed air ejected from the air pipe 7 can be effectively utilized to form a certain vacuum in the connector suction chamber 41, thereby sucking the RF connector 20 into the connector suction chamber 41. After the RF connector 20 is transported to a preset press-fit position (connector assembly point) with the press-fitting tool, it is released and press-fitted at the preset press-fitting position, thereby achieving the removal, placement, and installation of the RF connector 20. The RF connector 20 can be sucked conveniently and quickly, and the connector suction chamber 41 can limit the RF connector 20. Compared with flat suction, it can prevent the RF connector 20 from falling off after suction and facilitate the subsequent accurate positioning and placement of the sucked RF connector 20 in the preset press-fitting position to prevent the connector from shifting. The connector suction chamber 41 can also protect the RF connector 20 and prevent damage to the connector.

[0048] In some embodiments, as Figure 6 As shown, a sealing column 45 connected to the RF connector 20 is provided on the partition 43 to reliably absorb the RF connector 20 into the connector absorption cavity 41 .

[0049] In some embodiments, as Figure 6 As shown, a limiting step 46 for limiting the position of the RF connector 20 is provided in the connector suction cavity 41 to prevent the RF connector 20 from shifting after suction, thereby ensuring accurate assembly of subsequent connectors.

[0050] In some embodiments, the diameter of the connector suction cavity 41 matches the diameter of the RF connector 20. That is, the diameter of the RF connector 20 is slightly smaller than the diameter of the connector suction cavity 41. The connector suction cavity 41 can be configured according to the size of the RF connector 20 to meet the requirements of small-pitch assembly or narrow space assembly of the RF connector 20.

[0051] Optional, such as Figure 2 As shown, the depth of the connector suction cavity 41 is greater than 1 / 2 of the length of the RF connector 20 and less than the length of the RF connector 20, so that most of the structure of the RF connector 20 is located in the connector suction cavity 41, ensuring reliable suction of the RF connector 20; the exposed RF connector 20 can facilitate the assembly of the connector at the connector assembly point.

[0052] In some embodiments, as Figure 1 As shown, the mounting bracket 1 includes a top plate 11 and a side plate 12, the top plate 11 is installed on one side of the side plate 12, the force sensor 2 is installed on one side of the plate body of the top plate 11, and the other side of the plate body of the top plate 11 is used to connect with the transplanting mechanism, and the vacuum generator 5 is connected to the side plate 12 through the connecting bracket 51.

[0053] The top plate 11 is connected to the transfer mechanism on its upper side and to the force sensor 2 on its lower side. This allows the transfer mechanism to apply downward pressure to the suction head 4 through the top plate 11 to press it in place, and facilitates monitoring the assembly quality of the RF connector 20 through the force sensor 2. The side plates 12 are used to secure the top plate 11 and protect the force sensor 2, connecting rod 3, and suction head 4 from damage. The vacuum generator 5 is connected to the side plates 12 via a connecting bracket 51, facilitating its securement. The vacuum generator 5 can also quickly deliver compressed gas to the suction head 4 via the air pipe 7.

[0054] In some embodiments, as Figure 1 and Figure 3 As shown, the connecting rod 3 includes an extended pressure rod 31 and a connecting sleeve 32. One end of the extended pressure rod 31 is connected to the force sensor 2 through the adapter block 8, and the other end of the extended pressure rod 31 is connected to one end of the connecting sleeve 32. The other end of the connecting sleeve 32 is connected to the suction head 4 through the elastic member 6.

[0055] The connecting sleeve 32 can be pre-connected with the suction and pressure head 4 through the elastic member 6, and the tail of the suction and pressure head 4 can slide inside the connecting sleeve 32; then, the top of the connecting sleeve 32 is fixed to the bottom of the extended pressure rod 31 to realize the assembly of the force sensor 2, the connecting rod 3 and the suction and pressure head 4, which is convenient for assembly and disassembly.

[0056] In this embodiment, the connecting rod 3 is a split structure (including an extended pressure rod 31 and a connecting sleeve 32), which facilitates the installation of the suction head 4 and the replacement of the extended pressure rod 31, and has a wide range of applications. In other embodiments, the connecting rod 3 can be a hollow, integrated structure, and its specific structure is not specifically limited in this embodiment.

[0057] In some embodiments, as Figure 1 、 Figure 3 and Figure 5 As shown, the suction head 4 further includes a main body 47, a portion of which is located inside the connecting sleeve 32, and another portion is located outside the connecting sleeve 32. A connecting portion 48 is provided on the outer periphery of the main body 47 located outside the connecting sleeve 32. The elastic member 48 is sleeved on the main body 47 and located between the connecting portion 48 and the other end of the connecting sleeve 32. In this embodiment, the main body 47 is provided on the side of the suction head 4 facing the connecting sleeve 32, and the main body 47 is extended into the connecting sleeve 32 to facilitate the connection between the suction head 4 and the connecting sleeve 32. At the same time, a connecting portion 48 is provided on the outer periphery of the main body 47 located outside the connecting sleeve 32. The elastic member 48 is sleeved on the outer periphery of the main body 47 and located between the connecting portion 42 and the other end of the connecting sleeve 32 to ensure the reliable installation of the elastic member 6. The main body 47 can be used to guide the elastic member 6 for extension and contraction, thereby preventing the elastic member 6 from deflecting during extension and contraction.

[0058] Further, such as Figure 3 As shown, in order to ensure the reliability of the installation of the elastic part 6, the elastic part 6 can be extended into the other end of the connecting sleeve 32 and connected to the connecting sleeve 32, and the elastic part 6 can be radially limited to avoid the elastic part 6 being directly connected to the end of the other end of the connecting sleeve 32, resulting in unreliable connection between the two, and further causing the elastic part 6 to telescope and offset, etc.

[0059] In some embodiments, as Figure 1 As shown, the press tool also includes a linear bearing 91 and a linear bearing fixing seat 92. The linear bearing fixing seat 92 is connected to the side plate 12, and the linear bearing 91 is mounted on the linear bearing fixing seat 92. The extended pressure rod 31 passes through the linear bearing 91 and is connected to the linear bearing 91. The extended pressure rod 31 cooperates with the linear bearing 91 to ensure that the force-bearing surface of the force sensor 2 is subjected to vertical force, without lateral force, and accurately monitors the applied force. The linear bearing 91 is fixedly connected to the side plate 12 by the linear bearing fixing seat 92, which ensures that the linear bearing 91 is securely fixed.

[0060] In some embodiments, as Figure 1As shown, the mounting bracket 1 further includes a reinforcing rib 13, which is connected between the top plate 11 and the side plate 12. The top plate 11 and the side plate 12 are connected and then combined and connected by the reinforcing rib 3 to form a stable frame structure, ensuring the stability and reliability of the overall structure of the press tool.

[0061] The present application also provides a press-fitting method for a radio frequency connector, which is performed using the above-mentioned press-fitting tool, wherein the press-fitting tool is installed on a transplanting mechanism, and the press-fitting method includes:

[0062] S101: moving the pressing tool to a material taking position close to the RF connector 20 by the transplanting mechanism;

[0063] S102: After the suction and pressure head 4 moves downward to contact the RF connector 20 and compresses the elastic member 6, the vacuum generator 5 is turned on to suck the RF connector 20 through the suction and pressure head 4;

[0064] S103: Translocating the pressing tool to above the connector assembly point by the transplanting mechanism;

[0065] S104: The pressing tool is driven downward by the transfer mechanism, and a force is applied to the pressing tool by the pressing mechanism to press the RF connector 20 onto the connector assembly point;

[0066] S105 : During the assembly process of the RF connector, the force between the RF connector 20 and the connector assembly point is detected by the force sensor 2 , and the pressing force of the pressing mechanism is adjusted according to the force.

[0067] The pressing tool can be installed at the end of a transplanting mechanism such as a manipulator through a mounting bracket 1. The transplanting mechanism drives the pressing tool to move above the material picking position and aligns it with the RF connector 20 at that position. The transplanting mechanism drives the pressing tool to move down close to the RF connector 20. When the suction head 4 moves down to contact the RF connector 20, the elastic member 6 (such as a compression spring, an elastic sleeve) is compressed, which can form a buffer between the suction head 4 and the RF connector 20, ensuring that the RF connector 20 and the suction head 4 are not in hard contact, which helps to absorb the connector stably and quickly, and avoids damage to the RF connector 20 caused by hard contact between the suction head 4 and the RF connector 20; then, the vacuum generator 5 is opened, so that the suction head 4 can reliably absorb the RF connector 20; after the suction head 4 absorbs the RF connector 20, it is moved The planting mechanism drives the pressing tool to move above the connector assembly point. The moving mechanism drives the pressing tool downward and applies a force to the pressing tool through the pressing mechanism to press the RF connector 20 onto the connector assembly point. When the RF connector 20 is assembled, the force between the RF connector 20 and the connector assembly point is transmitted to the force sensor 2 through the connecting rod 3. The assembly status of the RF connector 20 during the pressing process is monitored in real time. The downward pressure of the pressing mechanism is adjusted according to the force (the pressing mechanism acts on the mounting bracket 1, and then acts on the suction head 4 through the force sensor 2 and the connecting rod 3) to prevent the connector from being inserted or over-pressurized, ensuring that the RF connector 20 is reliably assembled at the assembly point, ensuring product quality, and avoiding damage to the connector. For example, when the force is large, the downward pressure can be reduced to avoid damage to the RF connector 20; when the force is small, the downward pressure can be increased to ensure that the RF connector 20 is reliably assembled at the assembly point, avoiding loose assembly of the connector, etc.

[0068] In some embodiments, in step S102, sucking the RF connector 20 by the suction head 4 includes:

[0069] The RF connector 20 is adsorbed into the connector adsorption cavity 41 on the suction and pressure head 4 .

[0070] A connector suction chamber 41 is provided at the end of the suction and pressure head 4, and the RF connector 20 is adsorbed into the connector suction chamber 41.
