Description

Technical Field

[0001] This invention belongs to the technical field of slot waveguide antennas and their manufacturing equipment, and particularly relates to a slot antenna, welding fixture and assembly device. Background Technology

[0002] Existing tubular slot antennas, whether single-channel (single-tube structure) or dual-channel (dual-tube structure), all use a complete tube as the base material, and then form slots by milling the side wall of the tube. For example, the patent application number 201510051410.3 discloses a slot dual-waveguide antenna. After the slots are processed, the inner wall of the tube corresponding to the edge of the slot will have a lot of burrs or flash. Because this type of slot antenna is made of a complete tube, it is very difficult to clean the burrs and flash inside. It often requires multiple sandblasting processes, or even manual scraping, resulting in low production efficiency. Moreover, the internal quality of the slot antenna is not easy to guarantee. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a slotted antenna, a welding fixture, and an assembly device. The slotted antenna adopts a structure combining a substrate and a slotted plate. Before assembly, the slotting process and removal of burrs and flash are completed, which not only effectively ensures the quality of the inner wall of the slotted antenna but also makes the cleaning of burrs and flash more convenient.

[0004] In order to achieve the objective of this invention, the following solution is proposed:

[0005] A slot antenna includes: a substrate and a slotted plate. The slotted plate has a back plate and at least a pair of parallel side plates. The edges of the side plates of the slotted plate are sealed to the top surface of the substrate. The back plate and side plates of the slotted plate and the substrate form a signal channel for the slot antenna. Slots are provided on the back plate or the outer side plate of the slotted plate. The slots are arranged in an array along the extension direction of the signal channel.

[0006] Furthermore, the top surface of the substrate is provided with strip grooves corresponding to the side plate edges of the groove plate. The side plate edges of the groove plate are connected to the strip grooves by brazing. The two ends of the strip grooves do not penetrate the ends of the substrate.

[0007] Furthermore, the channel plate has a pair of side plates with a U-shaped cross-section, and the cracks are opened on the back plate or one of the side plates of the channel plate.

[0008] Furthermore, the channel plate has three side plates, with each signal channel corresponding to a crack being opened on the back plate of the channel plate, or each signal channel corresponding to a crack being opened on the outer side plate of the channel plate, or the crack of one signal channel being opened on the back plate of the channel plate and the crack of the other signal channel being opened on the outer side plate of the channel plate.

[0009] A welding fixture includes a lower clamping plate, an upper clamping plate, and a pressure plate for clamping the aforementioned slotted antenna.

[0010] The lower snap plate includes a horizontal plate and vertical plates perpendicular to both ends of the top surface of the horizontal plate. The vertical plates are all opened in U-shaped grooves perpendicular to the horizontal plate, and the extension direction of the U-shaped grooves is consistent with the length direction of the horizontal plate. The upper snap plate includes a top plate and connecting rods perpendicular to both ends of the bottom surface of the top plate. The connecting rods are connected to the U-shaped grooves by a snap-fit ​​structure. The two ends of the pressure plate are slidably connected to the connecting rods on both sides, and the pressure plate is parallel to the upper snap plate. A compression spring is provided between the pressure plate and the upper snap plate.

[0011] Furthermore, a screw is vertically provided on the top surface of the pressure plate. When assembling the slot antenna, the upper section of the screw passes upward through the top plate.

[0012] Furthermore, multiple inner retaining strips are arranged on both sides of the U-shaped groove in a direction perpendicular to the horizontal plate, and outer retaining strips that cooperate with the inner retaining strips are arranged on both sides of the connecting rod. Both the inner and outer retaining strips are parallel to the length direction of the horizontal plate.

[0013] An assembly apparatus is provided for assembling the aforementioned welding fixture to clamp a slotted antenna. The assembly apparatus includes: a main track for transporting the assembled slotted antenna; a lower track, parallel to the main track and positioned below it, for arranging and transporting lower mounting plates, with a lifting device located below the end of the lower track for lifting the lower mounting plates within the lower track upwards to a predetermined position; and an upper track, parallel to the main track and positioned above it, for arranging and transporting upper mounting plates, with a pressing device located at the end of the upper track directly above the lifting device for moving the upper mounting plates within the upper track downwards to a predetermined position; both the lifting device and the pressing device are located outside the end of the main track.

[0014] Furthermore, it also includes a transfer mechanism, which has a turntable with at least two sets of guide rods arranged in a circular array on one side of the turntable. Each set of guide rods has at least one rod body, the front end of which is perpendicular to the turntable. The turntable is set to rotate around an axis that is parallel to the conveying direction of the main track. When assembling the welding fixture, one set of guide rods is aligned with the signal channel of the slot antenna in the main track. As the slot antenna is output from the end of the main track, the rod body passes into the signal channel to achieve seamless docking.

[0015] Furthermore, a discharge pipe is provided at the lower end of the upper track. Baffles are hinged to the connecting rods on both sides of the bottom of the discharge pipe, corresponding to the two sides of the upper buckle plate. The baffles are automatically closed by springs. When the upper buckle plate at the end of the upper track is located inside the discharge pipe and the connecting rod is supported on the closed baffle, the top plate of the upper buckle plate is flush with the pressure plate on the adjacent upper buckle plate.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. In this application, the slot antenna is set as two independent structures: a substrate and a slot plate. The slot plate can be formed by processing before assembling the substrate and the slot plate. Furthermore, the burrs and flash are removed before assembly, which can effectively ensure the quality of the inner wall of the slot plate and make the cleaning of burrs and flash more convenient.

[0018] 2. The assembly and welding fixture can assemble and clamp the slotted antenna, ensuring the positional accuracy of the substrate and slotted plate during brazing, and can continuously apply pressure during the brazing process to keep the slotted plate tightly attached to the substrate.

[0019] 3. The assembly device can automatically assemble the upper and lower buckle plates onto the slot antenna and achieve automatic transfer, which can effectively improve the assembly efficiency of the welding fixture and accurately control the depth of the connecting rod inserted into the U-shaped groove to control the pre-pressure applied by the pressure plate to the slot plate.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0034] Example 1

[0035] like Figure 1 , Figure 4 As shown, a slot antenna includes a substrate 11 and a slotted plate 12. The slotted plate 12 has a back plate and at least a pair of parallel side plates. The edges of the side plates of the slotted plate 12 are sealed to the top surface of the substrate 11. The back plate and side plates of the slotted plate 12, together with the substrate 11, form a signal channel 13 for the slot antenna. Slots 121 are formed on the back plate or the outer side plate of the slotted plate 12, and the slots 121 are arrayed along the extension direction of the signal channel 13. This design sets the slot antenna as two independent structures: the substrate 11 and the slotted plate 12. The slots 121 on the slotted plate 12 can be formed before assembling the substrate 11 and the slotted plate 12, and the burrs and flash are removed before assembly, which effectively ensures the quality of the inner wall of the slotted plate 12, and the cleaning of burrs and flash is more convenient.

[0036] Preferably, the top surface of the substrate 11 is welded to the edge of the side plate of the grooved plate 12. Specifically, for example... Figure 1As shown, the top surface of the substrate 11 is provided with strip grooves 111 corresponding to the side edges of the groove plate 12. The side edges of the groove plate 12 are connected to the strip grooves 111 by brazing. Both sides of the side plate of the groove plate 12 have a chamfered structure to accommodate the solder. During assembly, the long strip of solder is first embedded in the strip groove 111, and then the side edges of the groove plate 12 are clamped in the strip groove 111. Then, the solder is melted by heating, so that the groove plate 12 and the substrate 11 are welded together to form a sealed connection structure.

[0037] Further preferred, such as Figure 1 As shown, the two ends of the strip groove 111 do not penetrate the end of the substrate 11 to prevent the molten solder from flowing out of the two ends of the strip groove 111 quickly.

[0038] Example 2

[0039] like Figure 4 As shown, a slot antenna includes: a substrate 11 and a slotted plate 12. The slotted plate 12 has a pair of side plates with a U-shaped cross-section, thereby forming a single-channel slot antenna with a signal channel 13. The slot 121 is formed on the back plate or one of the side plates of the slotted plate 12.

[0040] Preferably, the top surface of the substrate 11 is provided with strip grooves 111 corresponding to the side edges of the groove plate 12. The side edges of the groove plate 12 are connected to the strip grooves 111 by brazing, and the two ends of the strip grooves 111 do not penetrate the ends of the substrate 11.

[0041] Example 3

[0042] like Figures 1 to 3 As shown, a slot antenna includes a substrate 11 and a slotted plate 12, the slotted plate 12 having three side plates, thereby forming a dual-channel slot antenna with two signal channels 13.

[0043] As a first preferred embodiment, such as Figure 1 As shown, each signal channel 13 corresponding to the crack 121 is opened on the back plate of the slotted plate 12.

[0044] As a second preferred embodiment, such as Figure 2 As shown, each signal channel 13 corresponding to the crack 121 is opened on the outer side plate of the slotted plate 12.

[0045] As a third preferred embodiment, such as Figure 3 As shown, one of the signal channels 13 has a crack 121 on the back plate of the channel plate 12, and the other signal channel 13 has a crack 121 on the outer side plate of the channel plate 12.

[0046] Example 4

[0047] like Figure 5 , Figure 6 As shown, a welding fixture includes a lower clamping plate 21, an upper clamping plate 22 and a pressure plate 23, used to clamp the slotted antennas disclosed in Embodiments 1 to 3.

[0048] Specifically, such as Figure 5 As shown, the lower buckle plate 21 includes a horizontal plate 211 and vertical plates 212 that are perpendicular to both ends of the top surface of the horizontal plate 211. The vertical plates 212 are all opened in U-shaped grooves 213 that are perpendicular to the horizontal plate 211. The extension direction of the U-shaped grooves 213 is consistent with the length direction of the horizontal plate 211.

[0049] Specifically, such as Figure 5 As shown, the upper buckle plate 22 includes a top plate 221 and connecting rods 222 vertically disposed at both ends of the bottom surface of the top plate 221. The connecting rods 222 are connected to the U-shaped groove 213 by a snap-fit ​​structure.

[0050] Specifically, such as Figure 5 As shown, the two ends of the pressure plate 23 are slidably connected to the connecting rods 222 on both sides, and the pressure plate 23 is parallel to the upper buckle plate 22. A compression spring 24 is provided between the pressure plate 23 and the upper buckle plate 22.

[0051] During assembly, such as Figure 6 As shown, the substrate 11 is placed on the top surface of the horizontal plate 211 and positioned between the vertical plates 212. The slotted plate 12 is assembled onto the top surface of the substrate 11, and the upper buckle plate 22 is assembled so that the connecting rods 222 on both sides are respectively inserted into the U-shaped grooves 213 on both sides. The upper buckle plate 22 is pressed down onto the lower buckle plate 21, so that the pressure plate 23 presses down on the top surface of the slotted plate 12. The elastic force of the compression spring 24 is used to press the slotted plate 12 tightly onto the substrate 11. By adjusting the depth of the connecting rods 222 inserted into the U-shaped grooves 213, the elastic force of the compression spring 24 is controlled, thereby controlling the pressing force on the slotted plate 12. The pressure of the compression spring 24 is not only used for... The more important function of the clamping slotted plate 12 is to continue to provide pressure to move the slotted plate 12 toward the substrate 11 after the solder melts during welding. Because the pre-embedded solder has a solid structure, it will make the side edge of the slotted plate 12 and the bottom surface of the strip groove 111 spaced apart. After the solder melts, the pressure of the compression spring 24 will make the side edge of the slotted plate 12 fit tightly with the bottom surface of the strip groove 111 to ensure the outer contour size of the slotted antenna after assembly. At least two sets of assembly welding fixtures are used for a set of slotted antennas. After the substrate 11 and the slotted plate 12 are clamped by the assembly welding fixtures, they can be brazed together.

[0052] Preferred, such as Figure 5 As shown, a screw 231 is vertically provided on the top surface of the pressure plate 23, as... Figure 6As shown, when assembling the slot antenna, the upper section of the screw 231 passes upward through the top plate 221. After the assembly is completed, a nut 25 can be screwed into the upper section of the screw 231 to pull the screw 231 up, so that the pressure plate 23 can loosen the slot antenna, thereby making it easy to quickly remove the assembled slot antenna.

[0053] Preferred, such as Figure 5 , Figure 6 As shown, the inner walls of both sides of the U-shaped groove 213 are arrayed with multiple inner clamping strips 214 along a direction perpendicular to the horizontal plate 211. The outer walls of both sides of the connecting rod 222 are arrayed with outer clamping strips 223 that cooperate with the inner clamping strips 214. Both the inner clamping strips 214 and the outer clamping strips 223 are parallel to the length direction of the horizontal plate 211. When assembling and clamping the slotted antenna, this structure prevents the upper buckle plate 22 and the lower buckle plate 21 from moving relative to each other along the length direction of the horizontal plate 211 because the slotted antenna is located between the connecting rods 222 on both sides and the vertical plates 212 on both sides. This maintains the stability of the connection between the upper buckle plate 22 and the lower buckle plate 21, avoiding... The snap-fit ​​connection between the upper snap plate 22 and the lower snap plate 21 is released. However, after the slotted antenna is removed, the upper snap plate 22 and the lower snap plate 21 can be moved relative to each other along the length of the horizontal plate 211, thereby quickly releasing the snap-fit ​​connection between the upper snap plate 22 and the lower snap plate 21. Both the inner snap strip 214 and the outer snap strip 223 are serrated. The inclined surface of the serration of the inner snap strip 214 faces the upper middle part of the U-shaped groove 213, and the inclined surface of the serration of the outer snap strip 223 faces the lower sides of the connecting rod 222, thereby facilitating the smooth insertion of the connecting rod 222 into the U-shaped groove 213 to achieve the snap-fit ​​connection.

[0054] Example 5

[0055] An assembly apparatus is provided for assembling the welding fixture disclosed in Embodiment 4 to clamp the slotted antennas disclosed in Embodiments 1 to 3. The assembly apparatus includes a main rail 3, a lower rail 4, and an upper rail 5.

[0056] Specifically, main track 3 is used to transport the assembled slotted antenna.

[0057] Specifically, such as Figures 6 to 10 As shown, the lower rail 4 is arranged parallel to the main rail 3 below, and is used to arrange and transport the lower buckle plate 21. A lifting device 41 is provided at the lower end of the lower rail 4, which is used to lift the lower buckle plate 21 in the lower rail 4 to a predetermined position.

[0058] Specifically, such as Figures 6 to 10 As shown, the upper rail 5 is arranged parallel above the main rail 3 and is used to arrange and transport the upper buckle plate 22. At the end of the upper rail 5, directly above the lifting device 41, there is a pressing device 51, which is used to move the upper buckle plate 22 in the upper rail 5 downward to a predetermined position.

[0059] Specifically, such as Figure 8 , Figure 9 As shown, the lifting device 41 and the pressing device 51 are both located outside the end of the main track 3.

[0060] like Figure 9 , Figure 10 As shown, during assembly, when the slot antenna at the end of the main track 3 moves out of the predetermined position at the end of the main track 3, the lifting device 41 and the pressing device 51 are activated simultaneously. The lifting device 41 lifts the lower buckle plate 21 in the lower track 4 upward to the predetermined position, so that the horizontal plate 211 supports the bottom surface of the column base plate 11. The pressing device 51 moves the upper buckle plate 22 in the upper track 5 downward to the predetermined position, so that the connecting rod 222 is inserted into the U-shaped groove 213. The pressing depth of the pressing device 51 is adjusted to control the depth of the connecting rod 222 inserted into the U-shaped groove 213, thereby applying a predetermined pressure to the groove plate 12 through the compression spring 24, so that the groove plate 12 is tightly attached to the base plate 11 during brazing. When the slot antenna continues to output a predetermined distance, the lifting device 41 and the pressing device 51 are activated simultaneously. The lifting device 41 and the pressing device 51 reassemble another set of lower buckle plates 21 and upper buckle plates 22 onto the slit antenna. The position of the lower buckle plates 21 and upper buckle plates 22 assembled on the slit antenna for the first time can be determined by the proximity switch 31 set at the end of the main track 3. The timing of the second assembly can be determined by the delay set by the host computer. That is, after the proximity switch 31 detects the slit antenna, the second set of lower buckle plates 21 and upper buckle plates 22 will be assembled again. The pressing device 51 and the lifting device 41 are cylinders or linear motors. The lower track 4 and the upper track 5 can be moved by the telescopic cylinder set at the entrance end to push the lower buckle plates 21 or upper buckle plates 22, or by the spring set at the entrance end to automatically push the lower buckle plates 21 or upper buckle plates 22.

[0061] Preferred, such as Figures 6 to 10As shown, the assembly device also includes a transfer mechanism 6, which includes a turntable 61. One side of the turntable 61 is arranged in a circumferential array with at least two sets of guide rods. Each set of guide rods has at least one rod body 62. When the slot antenna has one signal channel 13, one rod body 62 is provided. When there are two signal channels 13, two rod bodies 62 can be provided to improve the stability during transfer. The front section of the rod 62 is perpendicular to the turntable 61, which rotates around an axis parallel to the conveying direction of the main track 3. When assembling the welding fixture, one set of guide rods aligns with the signal channel 13 of the slot antenna in the main track 3. As the slot antenna is output from the end of the main track 3, the rod 62 passes into the signal channel 13 to achieve seamless connection, thus securing and fixing the slot antenna and preventing it from falling off. After the hunting antenna completes the assembly of the welding fixture and is completely separated from the main track 3, the slot antenna can be moved away from the end of the main track 3 by rotating the turntable 61. At the same time, the other set of guide rods aligns with the main track 3. Then, the slot antenna holding the welding fixture can be taken out along the end of the rod 62. The transfer mechanism 6 can be set to quickly transfer the slot antenna, which helps to improve assembly efficiency. The turntable 61 is driven by a motor. In order to avoid the screw 231 protruding above the top plate 221, the push plate of the pressing device 51 can be set as an inverted concave structure.

[0062] Further preferred, such as Figure 11 As shown, a discharge pipe 52 is provided below the end of the upper track 5. Baffles 53 are hinged to the connecting rods 222 on both sides of the bottom of the discharge pipe 52, corresponding to the two sides of the upper buckle plate 22. The baffles 53 are automatically closed by springs. When the pressing device 51 pushes the upper buckle plate 22 downward, the baffles 53 are pushed downward through the connecting rods 222 so that the upper buckle plate 22 is disengaged from the upper track 5. When the upper buckle plate 22 at the end of the upper track 5 is located in the discharge pipe 52 and the connecting rods 222 are supported on the closed baffles 53, the top plate 221 of the upper buckle plate 22 is flush with the pressure plate 23 on the adjacent upper buckle plate 22. In this way, the pressure plate 23 on the adjacent upper buckle plate 22 is prevented from jamming the upper buckle plate 22 during the downward movement.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to be the only or limiting of the invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from its scope are all within the protection scope of the present invention.
