Description

Technical Field

[0001] This utility model relates to the field of SMT reflow soldering technology, specifically to an RF head auxiliary mounting carrier. Background Technology

[0002] With the rapid development of semiconductor 5G communication and radio frequency technology, when the design and structure of the THT hole cannot meet the requirements during the assembly of the radio frequency head, the fixing pads of the radio frequency head need to be designed on the GBP and GTP layers of the PCB board (i.e., the top and bottom layers of the PCB board).

[0003] Currently, most RF head components are supplied in tubular or plastic tray packages, requiring manual alignment and precise insertion before reflow soldering. However, when the RF head design is an interference fit with the PCB board thickness and the PCB thickness is within tolerance, manual insertion becomes extremely difficult. This not only results in low insertion efficiency and difficulty in ensuring insertion accuracy, but also easily leads to operator fatigue.

[0004] Therefore, there is an urgent need for an auxiliary installation tool that can improve the efficiency and accuracy of RF head insertion and reduce the difficulty of manual operation. Utility Model Content

[0005] In order to overcome the problems of low efficiency, poor accuracy and difficulty of manual operation in the existing technology of radio frequency head insertion, this utility model provides a radio frequency head auxiliary installation carrier to achieve accurate and efficient insertion of radio frequency heads and reduce the intensity of manual labor.

The RF head positioning base plate is provided with a first RF head placement groove for placing and positioning the RF head on the side close to the PCB positioning groove.

[0017] The RF head positioning flip cover has one side hinged to the same side of the RF head positioning base plate. A second RF head placement slot is provided on the side of the RF head positioning flip cover near the PCB positioning slot. The second RF head placement slot cooperates with the first RF head placement slot to position the RF head.

[0018] The linear slide rail connects the RF head positioning base plate to the carrier base plate and can move closer to or further away from the PCB positioning slot under the action of the RF head clamping assembly.

[0019] As a preferred embodiment of this utility model, one side of the RF head positioning base plate is hinged to the same side of the RF head positioning flip cover via a second hinge.

[0020] As a preferred embodiment of this utility model, the radio frequency head clamping assembly includes:

[0021] A hinge base is fixed to the base plate of the carrier. The hinge base has a hinge part at one end away from the PCB positioning groove, and a guide sleeve at the other end of the hinge base.

[0022] The clamping wrench is L-shaped, and the short end of the clamping wrench is hinged to the hinge part;

[0023] A guide post is slidably inserted through the guide sleeve, and one end of the guide post near the PCB positioning groove is connected to the RF head placement and positioning assembly.

[0024] A hinge, one end of which is hinged to the end of the guide post away from the PCB positioning groove, and the other end of which is hinged to the short end of the clamping wrench.

[0040] Please see Figure 1This utility model provides an auxiliary installation carrier for an RF head, including a carrier base plate 1, an RF head placement and positioning component 2, and an RF head clamping component 3. A PCB positioning groove 11 for placing and positioning a PCB board is provided on one side of the top of the carrier base plate 1. The RF head placement and positioning component 2 is installed in the middle of the top of the carrier base plate 1 and can be close to or away from the PCB positioning groove 11. An RF head placement groove for placing and positioning an RF head is provided on the side of the RF head placement and positioning component 2 close to the PCB positioning groove 11. The RF head clamping component 3 is located on the top side of the carrier base plate 1 away from the PCB positioning groove 11. The pressure end of the RF head clamping component 3 is connected to the RF head placement and positioning component 2 to move the RF head placement and positioning component 2 closer to or away from the PCB positioning groove 11.

[0041] In use, first place the PCB board into the PCB positioning slot 11 of the carrier base plate 1, then place the RF head into the RF head placement slot of the RF head placement and positioning component 2, and finally press the RF head on the RF head placement and positioning component 2 against the PCB board of the PCB positioning slot 11 by the RF head pressing component 3, so that the RF head can be accurately inserted into the corresponding mounting position on the PCB board to complete the installation.

[0042] It should be noted that the carrier can be equipped with PCB positioning slot 11 and RF head placement slot according to different PCB board sizes and RF head specifications to meet the assembly and soldering requirements of products with different PCB board sizes and RF head specifications.

[0043] In this embodiment, a mechanical structure is used to achieve precise alignment and stable pressing of the RF head and the PCB board, replacing manual alignment and insertion. This avoids the difficulty of insertion when there is an interference fit or when the PCB board thickness exceeds tolerance, significantly improving insertion efficiency. The positioning structure ensures the accuracy of the side insertion center, meeting the dimensional requirements of the product housing assembly and reducing rework due to insufficient accuracy. There is no need for manual forced insertion of the RF head; the insertion is driven by the mechanical force of the pressing component, avoiding the strain on operators caused by repeated force and reducing labor intensity. The carrier is lightweight and flexible, and the process of picking up and placing the PCB board and the RF head is simple, with a low operating threshold.

[0044] Please see Figure 2 In one embodiment, the RF head auxiliary mounting carrier further includes a PCB board protective cover 4, which is positioned above the PCB positioning slot 11 and hinged to the carrier base plate 1 on one side. When closed, the PCB board protective cover 4 can press the PCB board inserted into the PCB positioning slot 11 from above, preventing the PCB board from warping, shifting, or shaking due to forces (such as the reaction force of the RF head insertion) during insertion, thus further ensuring insertion accuracy. Simultaneously, the closed PCB board protective cover 4 provides physical protection, isolating the PCB board from potential external impacts during insertion and preventing scratches or damage to components and circuits on the PCB board surface.

[0045] Please see Figure 2 In one embodiment, the hinged side of the PCB board protective flip cover 4 is hinged to the carrier base plate 1 via a first hinge 5. The first hinge 5 provides a stable rotation axis, ensuring that the PCB board protective flip cover 4 does not tilt or jam when opening and closing, facilitating operators to quickly complete the process of placing the PCB board, closing the flip cover, inserting, opening the flip cover, and removing the PCB board, thus improving operational efficiency. At the same time, the first hinge 5 can limit the opening angle of the PCB board protective flip cover 4 (e.g., setting the maximum opening angle to 90° or 180°), avoiding collisions caused by excessive flipping of the PCB board protective flip cover 4.

[0046] Please see Figure 1 In one embodiment, the four corners of the bottom of the PCB positioning slot 11 are provided with positioning posts 111 that cooperate with the PCB board. When the PCB board is placed into the PCB positioning slot 11, the positioning posts 111 at the four corners will be inserted into the corresponding positioning holes of the PCB board to realize the rapid placement and fixation of the PCB board, ensuring that the PCB board does not shift during the insertion process, and providing an accurate reference for the alignment of the RF head.

[0047] Please see Figures 1 to 3In one embodiment, the RF head placement and positioning assembly 2 includes an RF head positioning base plate 21, an RF head positioning flip cover 22, and a linear slide rail 23. The side of the RF head positioning base plate 21 away from the PCB positioning groove 11 is connected to the pressure end of the RF head pressing assembly 3, and one side of the RF head positioning flip cover 22 is hinged to the same side of the RF head positioning base plate 21. The RF head positioning base plate 21 is slidably connected to the carrier base plate 1 through the linear slide rail 23, and can move closer to or further away from the PCB positioning groove 11 under the drive of the RF head pressing assembly 3, ensuring that the movement path of the assembly under the drive of the RF head pressing assembly 3 is strictly along a straight line, avoiding misalignment between the RF head and the PCB board mounting position due to skewed movement trajectory. The RF head positioning base plate 21 has a first RF head placement slot 211 on the side near the PCB positioning slot 11 for placing and positioning the RF head. The RF head positioning flip cover 22 has a second RF head placement slot 221 on the side near the PCB positioning slot 11. The second RF head placement slot 221 and the first RF head placement slot 211 cooperate to form an upper and lower wrap-around positioning. Through the cooperation of the two, the upper and lower surfaces of the RF head placement part can be limited simultaneously, which can effectively limit the posture deviation of the RF head before insertion (such as tilting, rotation, up and down movement, etc.), and ensure that its pin direction and insertion angle are completely matched with the PCB board mounting position. This avoids insertion offset caused by inaccurate positioning of the RF head itself from the source, and further ensures the side insertion center accuracy. Since the RF head positioning flip cover 22 can be opened / closed, the operator can easily put the RF head into the first RF head placement slot when the RF head positioning flip cover 22 is open, and complete the final fixation through the second RF head placement slot 221 after closing. Meanwhile, the closed RF head positioning flip cover 22 applies additional pressure to the RF head, which can counteract the reaction force on the RF head during insertion (such as the resistance of the interference fit of the PCB board), preventing it from coming out of the placement slot or shifting when it is pressed in, and ensuring the continuity of the insertion action.

[0048] Please see Figure 2 In one embodiment, one side of the RF head positioning base plate 21 is hinged to the same side of the RF head positioning flip cover 22 via a second hinge 24. The second hinge 24 provides a fixed rotation axis for the RF head positioning flip cover 22, ensuring that the RF head positioning flip cover 22 will not shift left or right or get stuck during opening / closing, so that the second RF head placement slot 221 can be accurately aligned with the first RF head placement slot 211, avoiding misalignment of the double positioning slots due to the tilt of the RF head positioning flip cover 22. At the same time, the second hinge 24 can limit the opening and closing angle of the RF head positioning flip cover 22 (e.g., setting the maximum opening and closing angle to 90° or 180°), avoiding collisions caused by excessive flipping of the RF head positioning flip cover 22.

[0049] Please see Figure 1 , Figure 2In one embodiment, the RF head clamping assembly 3 includes a hinge base 31, a clamping wrench 32, a guide post 33, and a hinge member 34. The hinge base 31 is fixed to the carrier base plate 1. The hinge base 31 has a hinge portion 311 at one end away from the PCB positioning groove 11, and a guide sleeve 312 at the other end. The clamping wrench 32 is L-shaped, and the short end of the clamping wrench 32 is hinged to the hinge portion 311. The guide post 33 slides through the guide sleeve 312, and the end of the guide post 33 near the PCB positioning groove 11 is connected to the RF head placement and positioning assembly 2. One end of the hinge member 34 is hinged to the end of the guide post 33 away from the PCB positioning groove 11, and the other end of the hinge member 34 is hinged to the short end of the clamping wrench 32. The structure consists of a hinge base 31, a clamping wrench 32, a guide post 33, and a hinge member 34. The operator only needs to operate the L-shaped clamping wrench 32 to easily move the RF head placement positioning component 2 closer to or further away from the PCB positioning slot 11 through the linkage of the hinge member 34 and the guide post 33, thus completing the insertion of the RF head. This mechanical linkage structure amplifies and transforms the operator's relatively small force, reducing the labor intensity of operation and improving the convenience of operation.

[0050] Please see Figure 4 In one embodiment, anti-slip support seats 6 are provided at each of the four bottom corners of the vehicle base plate 1. The anti-slip support seats 6 separate the vehicle base plate 1 from the workbench surface, preventing scratches and wear on the bottom of the vehicle base plate 1 and the workbench surface due to direct friction (such as when moving the vehicle). The anti-slip support seats 6 can enhance the friction between the vehicle and the workbench surface, preventing the vehicle from shifting or sliding under stress.

[0051] Preferably, the anti-slip support base 6 is made of rubber. Rubber (especially industrial abrasion-resistant rubber) has good wear resistance and can withstand long-term friction without easily being damaged. When the rubber anti-slip support base 6 comes into contact with the workbench surface, it can reduce friction noise generated when the carrier moves or is subjected to force, thus improving the acoustic experience of the production environment.

[0052] Please see Figure 1 , Figure 5 In one embodiment, the PCB positioning slot 11 has a pick-and-place slot 12 on at least one side. The pick-and-place slot 12 facilitates the worker to remove the PCB board from the PCB positioning slot 11 of the carrier base plate 1, simplifies the PCB board removal process, and shortens the single-piece operation time.

[0053] Please see Figure 1 , Figure 4 , Figure 5In one embodiment, the bottom of the PCB positioning slot 11 is provided with a first hollow clearance area 13, and the carrier base plate 1 is provided with a second hollow clearance area 14 to avoid and restrict the movement direction of the RF head placement positioning component 2. The second hollow clearance area 14 is connected to the first hollow clearance area 13. Since there may be protruding components (such as capacitors, connectors) and solder joints on the bottom of the PCB board, the first hollow clearance area 13 can reserve space to prevent these protruding structures from directly contacting the bottom of the positioning slot. If there is no clearance area, when the PCB board is placed into the PCB positioning slot 11, the board may warp or the components may be damaged due to the bottom protrusions being squeezed, or the positioning accuracy may be affected because it cannot fully fit the bottom of the slot. After the RF head is inserted into the PCB board, its tail or the extension of the pin will pass through the bottom of the PCB board. The first hollow clearance area 13 can provide a space to accommodate these extensions. The edge of the second hollow clearance area 14 can cooperate with the bottom structure of the RF head placement and positioning component 2, further assisting in guidance on the basis of the linear slide rail 23, ensuring the alignment accuracy of the RF head and the PCB board mounting position.
