Description

Technical Field

[0001] This application relates to the field of antenna and radio frequency technology, and in particular to a microwave radio frequency antenna fixture. Background Technology

[0002] Microwave radio frequency antennas are devices used for transmitting and receiving electromagnetic waves in microwave and radio frequency bands, and are widely used in fields such as communications, radar, and navigation.

[0003] Microwave radio frequency antenna boards are generally made of fiberglass board. In related technologies, operators manually apply glue to the antenna board for bonding or bonding, and then transport the cured antenna board to the subsequent production process. Due to the high coefficient of thermal expansion of fiberglass board, stress deformation is easily generated during the manufacturing process, resulting in serious deformation of the antenna board, which directly affects its electrical performance and signal transmission efficiency.

[0004] The above-mentioned method of manually applying glue to the antenna board results in poor consistency of manual operation, is time-consuming and labor-intensive, and makes it difficult to correct the deformation of the antenna board during the production process, leading to low production efficiency. Summary of the Invention

[0005] To address the problems of inconsistent manual application of adhesive to antenna boards, time-consuming and labor-intensive processes, and difficulty in correcting deformations during production, leading to low production efficiency, this application provides a microwave radio frequency antenna fixture. The fixture employs the following technical solution: it includes a base plate mounted on a dispensing machine, a support plate on the base plate, a positioning unit on the support plate to limit the position of the antenna board, a cover plate mounted on the support plate, and dispensing holes corresponding to the antenna board on the cover plate. The antenna board is pressed against the cover plate and the support plate, and the dispensing end of the dispensing machine passes through the dispensing holes to apply adhesive to the antenna board.

[0006] In one specific implementation, the limiting unit includes a limiting groove formed on the support plate and matching the antenna plate, the antenna plate is mounted in the limiting groove, a limiting pressure plate is provided on the wall of the dispensing hole, and the antenna plate abuts against the limiting pressure plate and the bottom of the limiting groove.

[0007] In one specific implementation scheme, the support plate is provided with a plurality of retrieval holes, and the plurality of retrieval holes are respectively connected to the limiting groove.

[0008] In one specific implementation scheme, the base plate is provided with a plurality of limiting blocks, and the plurality of limiting blocks form a limiting space that matches the bearing plate. The bearing plate is mounted on the base plate and located within the limiting space.

[0009] In one specific implementation scheme, the base plate is provided with a plurality of mounting holes, and mounting bolts are respectively passed through the plurality of limiting blocks, with one end of the plurality of mounting bolts facing the base plate being threaded into the plurality of mounting holes.

[0010] In one specific implementation, the bottom of the limiting groove is provided with a plurality of heat-conducting groups, each of the plurality of heat-conducting groups including a plurality of first heat-conducting holes formed on the bottom of the limiting groove, and the plurality of first heat-conducting holes are arranged in an array.

[0011] In one specific implementation, a second heat-conducting hole is provided between adjacent heat-conducting groups at the bottom of the limiting groove.

[0012] In one specific implementation, the surface of the support plate facing the base plate is provided with a stacking block that matches the limiting groove; when several support plates are stacked, the stacking block of the upper support plate is inserted into the limiting groove of the lower support plate.

[0013] In one specific implementation scheme, the limiting groove has several clearance grooves on its groove wall.

[0014] In one specific implementation, the support plate has several slots, and handles are inserted into the slots.

[0015] In summary, this application has the following beneficial technical effects: the position of the antenna plate is limited by the limiting unit, reducing the possibility of antenna plate position displacement during subsequent glue injection and curing. The antenna plate is pressed tightly between the cover plate and the carrier plate, and the cover plate is used to suppress the deformation of the antenna plate. The glue dispensing machine is started to perform glue dispensing operation on the antenna plate. Since the cover plate applies pressure to the antenna plate during the glue dispensing operation, it is easy to improve the consistency of glue dispensing height. Automated glue dispensing replaces manual bonding, reducing the error of manual operation. The glue dispensing and correction of antenna plate deformation are integrated into one, saving time and labor while improving the production efficiency of antenna plates.

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses a microwave radio frequency antenna fixture.

[0021] Reference Figure 1 and Figure 2 The microwave RF antenna fixture includes a base plate 1 mounted on a dispensing machine. In this embodiment, the base plate 1 is sized to match the worktable of the dispensing machine, and the base plate 1 is mounted on the worktable. A support plate 2 is mounted on the base plate 1, and a limiting unit for limiting the position of the antenna plate 16 is mounted on the support plate 2. A cover plate 3 is mounted on the support plate 2, and the support plate 2 is located between the base plate 1 and the cover plate 3. A dispensing hole 4 corresponding to the antenna plate 16 is opened on the cover plate 3. The antenna plate 16 is pressed against the cover plate 3 and the support plate 2, and the dispensing end of the dispensing machine passes through the dispensing hole 4 to dispense glue onto the antenna plate 16.

[0022] Therefore, by limiting the position of the antenna plate 16 through the limiting unit, the possibility of the antenna plate 16 shifting position during subsequent glue injection and curing is reduced. The antenna plate 16 is pressed tightly between the cover plate 3 and the carrier plate 2. The cover plate 3 is used to suppress the deformation of the antenna plate 16. The glue dispensing machine is started to perform glue dispensing operation on the antenna plate 16. Since the cover plate 3 applies pressure to the antenna plate 16 during the glue dispensing operation, it is easy to improve the consistency of the glue dispensing height. The use of automated glue dispensing to replace manual bonding reduces the error of manual operation. The glue dispensing and correction of the deformation of the antenna plate 16 are integrated into one, which saves time and effort and improves the production efficiency of the antenna plate 16.

[0023] Reference Figure 1 and Figure 2 The limiting unit includes a limiting groove 5 formed on the support plate 2 and matching the size of the antenna plate 16. In this embodiment, four limiting grooves 5 are used as an example, and the four limiting grooves 5 are evenly distributed on the support plate 2. The four antenna plates 16 are respectively mounted in the four limiting grooves 5. The limiting grooves 5 limit the position of the antenna plates 16, reducing the possibility of the antenna plates 16 shifting position during dispensing or curing, and improving the stability of the antenna plates 16. Limiting pressure plates 6 are fixedly connected to the hole wall of the dispensing hole 4. In this embodiment, four limiting pressure plates 6 are fixedly connected to the hole wall of each dispensing hole 4. The antenna plate 16 is pressed against the limiting pressure plate 6 and the bottom of the limiting groove 5. Under the action of its own weight, the limiting pressure plate 6 on the cover plate 3 applies pressure to the antenna plate 16 during the dispensing process, reducing the possibility of deformation of the antenna plate 16, facilitating the consistency of dispensing height, reducing the risk of uneven glue amount, glue leakage and impact, and improving the quality of the antenna plate 16.

[0024] Reference Figure 1 and Figure 2Four limiting blocks 8 are installed on the base plate 1. The four limiting blocks 8 form a limiting space that matches the size of the support plate 2. The support plate 2 is mounted on the base plate 1 and located within the limiting space. That is, the outer peripheral wall of the support plate 2 is in contact with the four limiting blocks 8 respectively. The four limiting blocks 8 limit the position of the support plate 2, reduce the possibility of positional displacement of the support plate 2, and improve the stability of the support plate 2 mounted on the base plate 1. Several mounting holes 9 are opened on the base plate 1, and mounting bolts are respectively inserted through the limiting blocks 8. The ends of the mounting bolts facing the base plate 1 are threaded into the mounting holes 9. The operator can remove the limiting blocks 8 from the base plate 1 by bolting, realizing the detachable connection of the limiting blocks 8. At the same time, the operator can also use the mounting holes 9 to bolt the base plate 1 to the worktable of the dispensing machine.

[0025] Reference Figure 1 and Figure 2 The bottom of the limiting groove 5 is provided with a plurality of heat-conducting groups 11, each of which includes a plurality of first heat-conducting holes 10 formed in the bottom of the limiting groove 5. The plurality of first heat-conducting holes 10 are arranged in an array. In this embodiment, each limiting groove 5 is provided with four groups of heat-conducting groups 11, and each heat-conducting group 11 includes four arrayed first heat-conducting holes 10. A second heat-conducting hole 12 formed in the bottom of the limiting groove 5 is provided between adjacent heat-conducting groups 11. In this embodiment, the first heat-conducting holes 10 are square, and the second heat-conducting holes 12 are rectangular. When the carrier plate 2 and the antenna plate 16 need to be loaded into the curing oven, the first heat-conducting holes 10 and the second heat-conducting holes 12 promote the uniform transfer of heat to the antenna plate 16 and the adhesive, thereby improving the efficiency of adhesive fixation on the antenna plate 16.

[0026] Reference Figure 1 and Figure 2 The carrier plate 2 has several retrieval holes 7, which communicate with the limiting grooves 5 to facilitate the operator's retrieval of the antenna plate 16. The limiting grooves 5 have several clearance grooves 14 on their walls. In this embodiment, each limiting groove 5 has four clearance grooves 14 located at its four corners. These clearance grooves 14 avoid the sharp edges of the rectangular antenna plate 16, reducing the possibility of interference between the limiting groove 5 and the antenna plate 16. The carrier plate 2 has several slots 15, each containing a handle. In this embodiment, there are two slots 15, and the handles are interference-fitted into both slots 15. When the carrier plate 2 needs to be retrieved, the operator inserts the handle into the slot 15 for easy and convenient retrieval.

[0027] Reference Figure 1 and Figure 2A stacking block 13, matching the size of the limiting groove 5, is fixedly connected to the surface of the support plate 2 facing the base plate 1. When several support plates 2 are stacked, the stacking block 13 of the upper support plate 2 is inserted into the limiting groove 5 of the lower support plate 2, thereby facilitating the stable stacking of multiple support plates 2 in the vertical direction. In this embodiment, five support plates 2 are usually stacked into a group. During stacking, a counterweight can be placed on the top support plate 2 to provide pressing force to the antenna plate 16 according to the actual situation on site. The pressing of the antenna plate 16 by the stacking block 13 further reduces the possibility of deformation of the antenna plate 16.

[0028] The implementation principle of this application embodiment is as follows: four sets of antenna plates 16 to be glued are placed in the limiting grooves 5 of the carrier plate 2. The carrier plate 2 is mounted on the base plate 1, so that the carrier plate 2 is located between the four limiting blocks 8 and in contact with the four limiting blocks 8 respectively. The base plate 1 is fixed on the fixed platform of the glue dispensing machine. Then, the cover plate 3 is mounted on the carrier plate 2, so that the four glue dispensing holes 4 on the cover plate 3 correspond to the four sets of antenna plates 16 respectively. The antenna plates 16 are pressed between the limiting pressure plate 6 and the carrier plate 2. The cover plate 3 is used to suppress the deformation of the antenna plates 16. The glue dispensing machine is started to perform glue dispensing operation on the antenna plates 16. Since the cover plate 3 applies pressure to the antenna plates 16 during the glue dispensing operation, it is easy to improve the consistency of the glue dispensing height. Automated glue dispensing replaces manual bonding, reducing the error of manual operation. The glue dispensing and correction of the deformation of the antenna plates 16 are integrated into one, saving time and effort while improving the production efficiency of the antenna plates 16.

[0029] After the adhesive is applied, the operator removes the cover plate 3 and takes out five carrier plates 2 with antenna plates 16. The stacking block 13 of the upper carrier plate 2 is inserted into the limiting groove 5 of the lower carrier plate 2, so that the five carrier plates 2 are stacked into a batch through the stacking block 13. A counterweight is placed on the uppermost carrier plate 2 to provide pressing force. Finally, the entire batch is moved into the curing oven. The first heat conduction hole 10 and the second heat conduction hole 12 promote the uniform transfer of heat to the antenna plate 16 and the adhesive, reducing the possibility of secondary deformation caused by local overheating of the antenna plate 16. After the antenna plate 16 is cured, the operator inserts the handle into the slot 15 on the side of the carrier plate 2 and takes the carrier plate 2 with the antenna plate 16 out of the curing oven for subsequent processes.

[0030] The microwave RF antenna fixture serves as the carrier for the entire process of antenna board 16 from dispensing to curing, reducing intermediate steps and integrating deformation control, efficient dispensing, and batch curing. Its modular design is compatible with standard dispensing machine platforms, requiring no equipment modification. During the dispensing stage, the mechanical pressure of the cover plate 3 and the limiting pressure plate 6 corrects the deformation of the fiberglass antenna board 16 in real time, ensuring a dispensing flatness of ≤0.1mm. When the carrier plates 2 are stacked, the weight of the carrier plates 2 and the counterweights provide continuous and uniform pressure (≥5kPa) while achieving batch curing, eliminating gaps in the adhesive layer of the antenna board 16. Furthermore, the carrier plate 2 can simultaneously limit four sets of antenna boards 16, improving single-dispensing efficiency. The design of the first heat-conducting hole 10 and the second heat-conducting hole 12 reduces curing time, improves heat transfer efficiency, and achieves a curing temperature uniformity of ±2℃, enhancing the bonding strength of the adhesive layer of the antenna board 16. The slots 15 on the sidewalls of the carrier plate 2 support quick insertion and removal of handles, reducing the difficulty of handling the carrier plate 2.
