Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna component welding and processing technology, and in particular to a height-adjustable PCB vibrator clamp. Background Technology
[0002] In the process of welding antenna components, the clamping of PCB vibrators is one of the key steps. However, the Z-axis height of traditional clamps is mostly fixed, and the distance between the upper and lower cover plates cannot be adjusted once it is formed. This means that a single clamp can only accommodate PCB vibrators of one thickness and feed plates of a specific height.
[0003] This fixed-height design has brought about many problems: on the one hand, manufacturers need to customize multiple sets of fixtures for products of different specifications, which not only increases the manufacturing cost of the fixtures, but also requires additional investment in storage space and management costs; on the other hand, in the production mode of multiple varieties and small batches, frequent changes of fixtures will lead to increased production line downtime, which will seriously affect production efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a fixture that can flexibly adjust the Z-axis height and adapt to PCB oscillators and feed plates of different specifications, thereby reducing production costs and improving production efficiency.
[0005] To achieve the purpose of this utility model, the following technical solution is adopted:
[0006] A height-adjustable PCB oscillator clamp is used to clamp and fix an oscillator assembly to be soldered. The clamp includes an upper cover plate, a lower cover plate, support columns, and height adjustment screws. The upper and lower cover plates are used to clamp the oscillator assembly from above and below. The support column is a hollow columnar structure with an internal thread on its hollow inner wall that matches the height adjustment screw. Several support columns are fixedly installed on the lower cover plate, and a height adjustment screw is installed on the top of each support column through the internal thread. The upper cover plate is provided with several snap-fit parts that match the height adjustment screws. The upper cover plate is snapped and fixed to the screw head of the height adjustment screw through the snap-fit parts, thereby achieving the clamping of the oscillator assembly.
[0007] A further improvement is that a threaded hole is provided on the side wall of the support column, and a grommet screw is screwed into the threaded hole. The grommet screw is used to position and lock the height adjustment screw.
[0008] A further improvement is that the support column is a hexagonal prism.
[0009] A further improvement is that a limiting groove is formed on the surface of the lower cover plate. The limiting groove is used to place the oscillator assembly and limit the power distribution base plate of the oscillator assembly in the front, back, left, and right directions.
[0010] A further improvement is that a second cutout is provided on the limiting groove corresponding to the lower welding position of the oscillator assembly, which penetrates the lower cover plate. The second cutout is used to expose the lower welding position of the oscillator assembly.
[0011] A further improvement is that the lower cover plate is provided with a fixing hole that penetrates the lower cover plate, and the outer diameter of the support column is larger than the diameter of the fixing hole. The fixing hole is used to cooperate with bolts to fix the support column to the lower cover plate.
[0012] A further improvement is that the upper cover plate is provided with a first cutout through the upper cover plate corresponding to the upper welding position of the oscillator assembly, the first cutout being used to expose the upper welding position of the oscillator assembly.
[0013] A further improvement is that the locking part includes a first clearance hole and a first sliding groove penetrating the upper cover plate. The first clearance hole and the first sliding groove are connected. The first clearance hole is used for the height adjustment screw to pass through, and the first sliding groove is used for the height adjustment screw to slide to the locking position. A protruding limiting step is provided on the inner wall of the first sliding groove. The top surface of the limiting step is used to abut against the bottom surface of the screw head of the height adjustment screw to achieve locking.
[0014] A further improvement is that the diameter of the first clearance hole is larger than the outer diameter of the screw head.
[0015] A further improvement is that the number of the first cutout and the number of the second cutout are both two.
[0016] The beneficial effects of this utility model are as follows:
[0017] This utility model provides a height-adjustable PCB oscillator clamp. Through the design of a height-adjusting screw, a hollow support column, and a top cover plate locking structure, the clamp's Z-axis height can be flexibly adjusted to accommodate PCB oscillators and feed plates of different heights. Combined with the lower cover plate's limiting groove, it allows for precise positioning of the oscillator assembly in the front, back, left, and right directions. The hollowed-out sections of the upper and lower cover plates expose the soldering positions, facilitating soldering operations. A mortise screw is used to lock the height-adjusting screw, preventing height deviation caused by vibration and enhancing clamping stability. The sliding upper cover plate enables quick clamping and release, improving operational convenience and production efficiency, significantly increasing productivity. Attached Figure Description

[0032] Please refer to the attached document. Figure 1 -Appendix Figure 8 This utility model embodiment proposes a height-adjustable PCB oscillator clamp 100 for clamping and fixing the oscillator assembly 1050 to be soldered.
[0033] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the oscillator assembly 1050 includes a radiating plate 1051, an upper feed plate 1052, a lower feed plate 1053, and a power divider base plate 1054. The upper feed plate 1052 and the lower feed plate 1053 are provided with solder pads and are mounted in the power divider base plate 1054. A single power divider base plate 1054 is assembled with two sets of radiating plates 1051, upper feed plates 1052, and lower feed plates 1053 to form a one-support-two-oscillator assembly 1050, forming 32 solder points on both the front and back sides.
[0034] The detailed structure and operating principle of the PCB oscillator fixture 100 in this embodiment are explained below:
[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3As shown, the PCB oscillator clamp 100 includes an upper cover plate 1010, a lower cover plate 1020, support columns 1030, and height adjusting screws 1040. The upper cover plate 1010 and the lower cover plate 1020 are used to clamp the oscillator assembly 1050 from above and below. The support column 1030 is a hollow columnar structure, and its hollow inner wall is provided with internal threads adapted to the height adjusting screws 1040. Several support columns 1030 are fixedly installed on the lower cover plate 1020. Each support column 1030 has a height adjusting screw 1040 installed on its top through internal threads. The upper cover plate 1010 is provided with several snap-fit parts adapted to the height adjusting screws 1040. The upper cover plate 1010 is snap-fitted and fixed to the screw head of the height adjusting screw 1040 through the snap-fit parts, thereby realizing the clamping of the oscillator assembly 1050.
[0036] Specifically, in this embodiment, the support column 1030 is a hexagonal prism. There are six support columns 1030, evenly distributed around the perimeter of the lower cover plate 1020. Correspondingly, there are also six snap-fit parts, each corresponding to one of the support columns 1030. Of course, those skilled in the art can adjust the number of support columns 1030 and snap-fit parts according to actual needs.
[0037] It is understood that the height adjustment screw 1040 is screwed into the internal threaded hole of the support column 1030. By rotating the height adjustment screw 1040, its extension length can be controlled, thereby changing the height of the screw head to adapt to the oscillator assembly 1050 of different heights. After adjusting the height of the height adjustment screw 1040 on each support column 1030, the upper cover plate 1010 can be used to press the oscillator assembly 1050 to be welded at the set height, and the oscillator assembly 1050 is clamped by the snap-fit part engaging with the screw head of the height adjustment screw 1040.
[0038] In a preferred embodiment, the support column 1030 has a threaded hole extending through the side wall, and a grommet screw 1060 is screwed into the threaded hole. The grommet screw 1060 is used to position and lock the height adjustment screw 1040.
[0039] Understandably, after setting the required distance between the upper cover plate 1010 and the lower cover plate 1020 by rotating the height adjustment screw 1040, the caliper screw 1060 is tightened so that its end presses against the outer wall of the height adjustment screw 1040. The caliper screw 1060 serves a locking and positioning function, preventing the height adjustment screw 1040 from loosening or shifting due to vibration or external force, thereby ensuring that the gap between the upper feed plate 1052, the lower feed plate 1053, the power divider base plate 1054, and the radiating plate 1051 is controlled within 1mm.
[0040] In a preferred embodiment, a limiting groove 1022 is formed on the surface of the lower cover plate 1020. The limiting groove 1022 is used to place the oscillator assembly 1050 and limit the power divider base plate 1054 of the oscillator assembly 1050 in the front, back, left and right directions, which can effectively prevent the power divider base plate 1054 from shifting position on the lower cover plate 1020.
[0041] Understandably, the power divider base plate 1054 of the oscillator assembly 1050 is placed into the limiting groove 1022 of the lower cover plate 1020. The limiting groove 1022 provides front, rear, left, and right direction limiting constraints on the power divider base plate 1054 through its inner wall. Combined with the pressing action of the upper cover plate 1010, a complete six-way spatial positioning is formed, ensuring that the oscillator assembly 1050 does not shift or misalign during the welding process.
[0042] In this embodiment, the limiting groove 1022 is provided with a second hollowed-out position 1023 that penetrates the lower cover plate 1020, corresponding to the lower welding position of the oscillator assembly 1050. The second hollowed-out position 1023 is used to expose the lower welding position of the oscillator assembly 1050. There are two second hollowed-out positions 1023.
[0043] Understandably, when the power divider base plate 1054 of the oscillator assembly 1050 is placed into the limiting groove 1022, the power divider base plate 1054 is precisely positioned by the limiting groove 1022. Simultaneously, the lower welding position of the oscillator assembly 1050 is aligned with the second cutout position 1023 on the lower cover plate 1020, exposing the lower welding position of the oscillator assembly 1050 for easy welding. Furthermore, the number of the second cutout positions 1023 can be set according to the actual situation of the lower welding position.
[0044] In this embodiment, the lower cover plate 1020 is provided with a fixing hole 1021 that penetrates the lower cover plate 1020. The outer diameter of the support column 1030 is larger than the diameter of the fixing hole 1021. The fixing hole 1021 is used to cooperate with bolts to fix the support column 1030 to the lower cover plate 1020.
[0045] Understandably, the support column 1030 is placed in the preset position of the lower cover plate 1020, with its internal threaded hole aligned with the fixing hole 1021 on the lower cover plate 1020. Then, a bolt is inserted from the bottom of the lower cover plate 1020 and tightened to complete the installation and fixing of the support column 1030.
[0046] In this embodiment, the upper cover plate 1010 is provided with a first hollow position 1013 that penetrates through the upper cover plate 1010, corresponding to the upper welding position of the oscillator assembly 1050. The first hollow position 1013 is used to expose the upper welding position of the oscillator assembly 1050. There are two first hollow positions 1013.
[0047] It is understandable that by providing a first perforation 1013 through the thickness of the upper cover plate 1010, after the oscillator assembly 1050 is clamped by the upper cover plate 1010 and the lower cover plate 1020, its upper welding position is located directly below the first perforation 1013, thus exposing the upper welding position of the oscillator assembly 1050 for easy welding. Similarly, the number of the first perforation 1013 can be set according to the actual situation of the upper welding position.
[0048] In a preferred embodiment, the locking part includes a first clearance hole 1011 and a first sliding groove 1014 penetrating the upper cover plate 1010. The first clearance hole 1011 and the first sliding groove 1014 are connected. The first clearance hole 1011 is used for the height adjustment screw 1040 to pass through. The first sliding groove 1014 is used for the height adjustment screw 1040 to slide to the locking position. A protruding limiting step 1012 is provided on the inner wall of the first sliding groove 1014. The top surface of the limiting step 1012 is used to abut against the bottom surface of the screw head of the height adjustment screw 1040 to achieve locking. The diameter of the first clearance hole 1011 is larger than the outer diameter of the screw head.
[0049] As a preferred embodiment, since the upper cover plate 1010 and the lower cover plate 1020 need to work at high temperatures for a long time, both the upper cover plate 1010 and the lower cover plate 1020 are made of high-temperature resistant synthetic stone material, which can reduce deformation in high-temperature environments, ensure clamping accuracy, and help improve welding quality.
[0050] The working principle of this utility model is as follows: After adjusting the height of the appropriate height adjustment screw 1040 in advance and locking it with the grommets 1060, the power divider base plate 1054 is placed into the limiting groove 1022 of the lower cover plate 1020. Then, the lower feed plate 1053, the upper feed plate 1052, and the radiating plate 1051 are assembled in sequence. Then, the upper cover plate 1010 is inserted from above, allowing the height adjustment screw 1040 to pass through the first clearance hole 1011. Then, the upper cover plate 1010 is slid, and at this time, the height adjustment screw 1040 slides along the first sliding groove 1014. The screw head of the height adjustment screw 1040 slides into the area of the limiting step 1012. The top surface of the limiting step 1012 abuts against the bottom surface of the screw head, forming a stable snap-fit and completing the clamping action. After clamping, the PCB oscillator fixture 100 can be placed into the conveyor line for welding work. If disassembly is required, slide the upper cover plate 1010 in the opposite direction until the screw head disengages from the limiting step 1012, thus releasing the snap-fit state.
[0051] This utility model provides a height-adjustable PCB oscillator clamp 100. Through a height-adjusting screw 1040, a hollow support column 1030, and a snap-fit structure with an upper cover plate 1010, the clamp's Z-axis height can be flexibly adjusted to accommodate PCB oscillators and feed plates of different heights. Combined with the limiting groove 1022 of the lower cover plate 1020, the oscillator assembly 1050 can be precisely positioned in the front, back, left, and right directions. The hollowed-out positions of the upper cover plate 1010 and lower cover plate 1020 expose the soldering positions, facilitating soldering operations. A mortise screw 1060 is used to lock the height-adjusting screw 1040, preventing height deviation caused by vibration and enhancing clamping stability. Quick clamping and releasing are achieved by sliding the upper cover plate 1010, improving operational convenience and production efficiency, significantly increasing productivity.
[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements are all protected by this utility model.
