Description

Technical Field

[0001] This invention relates to the field of waveguide antenna alignment systems, and more particularly to an automatic alignment system for waveguide antennas that can be precisely assembled. Background Technology

[0002] The waveguide antenna connector is indeed a critical component, responsible for efficiently transmitting signals received or transmitted by the antenna to a circuit board or other devices. This connector typically features a precision waveguide structure to ensure efficient and accurate signal transmission. Such connectors may include snap-fit ​​contacts or other forms of connection mechanisms for a reliable electrical connection with the interface on the circuit board. The circuit board interface is a specific area on the circuit board designed to mate with the waveguide antenna connector. This interface typically includes metal contacts, slots, or other connection mechanisms for receiving and transmitting signals from the waveguide antenna connector. The arrangement and shape of these contacts or slots usually match the contacts or plugs on the waveguide antenna connector to ensure a tight and reliable connection. During the connection process, the snap-fit ​​contacts (or other connection mechanisms) on the waveguide antenna connector side and the circuit board interface side must first be aligned. Alignment is a crucial step in ensuring a proper connection, helping to avoid distortion and attenuation in signal transmission. However, existing waveguide antennas generally have low levels of automation in their assembly with circuit boards, lacking efficient automated processes and closed-loop control systems. This results in lengthy assembly processes, extended production cycles, and difficulty in meeting market demands for efficient and rapid production. Summary of the Invention

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic alignment system for precisely assembled waveguide antennas, comprising: a monitoring mechanism, an adjustment mechanism disposed inside the monitoring mechanism, and a gripping mechanism disposed above the monitoring mechanism.

[0005] The adjustment mechanism includes: a base, a rotating component disposed on the base, and a wobbling component disposed on one side of the rotating component; both the rotating component and the wobbling component are used to adjust the angle of the waveguide antenna to align with a specific contact point on the circuit board;

[0006] The gripping mechanism includes: a linear slide rail assembly, a pressing component mounted on the linear slide rail assembly, and a pneumatic suction cup mounted on the pressing component; the pneumatic suction cup is used to adsorb the waveguide antenna, and the linear slide rail assembly is fixedly connected to the monitoring mechanism;

[0007] The monitoring mechanism includes: a base, a mounting bracket on the base, and a monitoring component on one side of the mounting bracket; both the mounting bracket and the monitoring component are located directly below the linear guide rail assembly, and the monitoring component is used to prevent the circuit board from being fixed.

[0008] In a preferred embodiment of the present invention, the rotating assembly includes a first motor, a first drive group, and a rotating group. The first motor is fixedly connected to the base, and both the first drive group and the rotating group are rotatably connected to the base.

[0009] In a preferred embodiment of the present invention, the first drive group includes a first worm gear and a first worm meshing with the first worm gear, both of which are rotatably connected to the base.

[0010] In a preferred embodiment of the present invention, the rotating assembly includes a sleeve shaft and a bent plate fixedly connected to the sleeve shaft. The bent plate is U-shaped. The sleeve is fixedly connected to the first worm gear and rotatably connected to the base.

[0011] In a preferred embodiment of the present invention, the swaying component includes a second motor, a second drive group, and a swaying group, wherein the second motor and the second drive group are fixedly connected.

[0012] In a preferred embodiment of the present invention, the second drive group includes a second worm gear, a second worm, and a wobbling shaft. The second material meshes with the second worm, and the wobbling shaft is fixedly connected to the second worm gear. The wobbling shaft is disposed through a sleeve shaft.

[0013] In a preferred embodiment of the present invention, the swaying assembly includes a plurality of bevel gears and a short shaft fixedly connected to the bevel gears; the bevel gears are arranged in a vertical meshing configuration, the two ends of the short shaft are slidably connected to the bending plate, a connecting shaft is fixedly connected in the middle of the short shaft, the connecting shaft passes through the base, and a placement plate is fixedly connected to the top.

[0014] In a preferred embodiment of the present invention, the monitoring component includes a monitoring frame and an infrared rangefinder disposed around the monitoring frame, the monitoring frame being used to fix the circuit board.

[0016] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0017] (1) This invention provides an automated alignment system for precisely assembled waveguide antennas. Through the coordinated use of a rotating component and a shaking component, the rotating component drives the waveguide antenna on the placement plate to rotate, aligning it angularly with a specific contact point on the circuit board. Then, the shaking component moves the waveguide antenna directly beneath the circuit board, ensuring complete alignment with the specific contact point. Compared to existing technologies that use automated alignment systems for high-precision positioning and assembly of waveguide antennas, this significantly reduces errors caused by human operation, thereby improving the overall assembly accuracy of the product. Simultaneously, the automated process accelerates the assembly process, shortens the production cycle, and improves production efficiency.

[0018] (2) This invention provides an automatic alignment system for waveguide antennas that can be precisely assembled. By using the cooperation between the adjustment mechanism and the monitoring mechanism, the system monitors and adjusts the alignment process of the adjustment mechanism in real time using an infrared rangefinder. This allows the system to measure and feed back position deviation information in real time and accurately during the alignment operation of the adjustment mechanism. Based on this real-time data, the system can intelligently adjust the adjustment mechanism to ensure that the waveguide antenna assembly can quickly and accurately reach the predetermined assembly position. This not only greatly improves the accuracy and efficiency of assembly, but also effectively avoids the cumulative errors that may occur in the traditional assembly process through closed-loop control of real-time monitoring and real-time adjustment, providing a brand-new solution for the precise assembly of waveguide antennas.

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] As shown in the figure, an automatic alignment system for waveguide antennas that can be precisely assembled includes: a monitoring mechanism, an adjustment mechanism disposed inside the monitoring mechanism, and a gripping mechanism disposed above the monitoring mechanism.

[0031] It should be noted that the adjustment mechanism is mainly located on the inner side of the bottom of the monitoring mechanism, while the gripping mechanism is located on the outer side of the top of the monitoring mechanism. The gripping mechanism is used to grip the waveguide antenna and move it onto the adjustment mechanism. Then, the adjustment mechanism adjusts the angle of the waveguide antenna and places the circuit board on the monitoring mechanism to align the waveguide antenna with the circuit board.

[0032] The adjustment mechanism includes: a base, a rotating component disposed on the base, and a wobbling component disposed on one side of the rotating component; both the rotating component and the wobbling component are used to adjust the angle of the waveguide antenna to align with a specific contact point on the circuit board;

[0033] In this invention, the rotating assembly includes a first motor, a first drive group, and a rotating group. The first motor is fixedly connected to the base, and both the first drive group and the rotating group are rotatably connected to the base. The first drive group includes a first worm wheel and a first worm meshing with the first worm wheel, and both the first worm wheel and the first worm are rotatably connected to the base. The rotating group includes a sleeve shaft and a bent plate fixedly connected to the sleeve shaft. The bent plate is U-shaped, and the sleeve is fixedly connected to the first worm wheel and rotatably connected to the base.

[0034] It should be noted that the base is n-shaped, with both ends fixedly connected to the base. The first drive group is located inside the n-shape of the base, and the first worm gear and the first worm are meshed together. Both the first worm gear and the first worm are rotatably connected to the base. The sleeve bearing is hollow, with its two ends fixedly connected to the first worm gear and the bending plate, respectively. The middle position of the sleeve shaft passes through the top horizontal middle position of the base. The first motor is a servo motor, which is fixedly connected to the base. At the same time, the output shaft of the first motor is fixedly connected to the first worm, so that the forward and reverse rotation of the first motor drives the sleeve shaft to rotate forward and reverse through the first worm gear and the first worm, thereby driving the bending plate to rotate forward and reverse in the horizontal direction.

[0035] In this invention, the shaking assembly includes a second motor, a second drive group, and a shaking group. The second motor is fixedly connected to the second drive group. The second drive group includes a second worm gear, a second worm, and a shaking shaft. The second material meshes with the second worm, and the shaking shaft is fixedly connected to the second worm gear. The shaking shaft is disposed through a sleeve shaft. The shaking group includes several bevel gears and a short shaft fixedly connected to the bevel gears. The bevel gears are arranged in a vertical meshing configuration. The two ends of the short shaft are slidably connected to the bending plate. A connecting shaft is fixedly connected in the middle of the short shaft. The connecting shaft passes through the base, and a placement plate is fixedly connected to the top.

[0036] It should be noted that the second drive group is also located inside the n-shaped base. The second worm and the second worm wheel are also meshed and rotatably connected to the base. The second worm wheel is located directly below the first worm wheel, and the second worm is located on the base on the symmetrical side of the first worm. The swaying shaft is fixedly connected to the second worm wheel and passes through the center of the first worm wheel, located in the hollow part inside the sleeve shaft. There are two bevel gears, which are also meshed. The two bevel gears are meshed vertically. The horizontally positioned bevel gear is fixedly connected to the connecting shaft, and the center of the vertically positioned bevel gear is fixedly connected to the short shaft. The two ends of the short shaft are slidably connected to the bending plate, and the middle of the short shaft is fixedly connected to the connecting shaft. The output of the second motor is fixedly connected to the second worm gear. The second motor is a servo motor. The forward and reverse rotation of the second motor drives the forward and reverse rotation of the wobbling shaft through the second worm gear and the second worm wheel. The vertically set bevel gear drives the angle offset of the connecting shaft. As the second motor reciprocates forward and reverse, it drives the angle of the connecting shaft to shift left and right, thereby causing the placement plate to wobble left and right in the vertical direction. The placement plate is long and narrow with a U-shaped cross-section in the middle. The width of its inner recess is just enough to accommodate a waveguide antenna. As the placement plate wobbles left and right, it causes the waveguide antenna to slide down or wobble, so that the waveguide antenna is aligned with the position of the circuit board.

[0037] The gripping mechanism includes: a linear slide rail assembly, a pressing component mounted on the linear slide rail assembly, and a pneumatic suction cup mounted on the pressing component; the pneumatic suction cup is used to adsorb the waveguide antenna, and the linear slide rail assembly is fixedly connected to the monitoring mechanism;

[0038] It should be noted that the linear guide rail assembly includes a support frame, a guide rail, a slider slidably connected to the guide rail, and a slide plate fixedly connected to the slider. The guide rail is fixed to both sides of the support frame, and two synchronous pulleys are also fixedly connected to one side of the support frame. A synchronous motor is fixedly connected to the bottom of one of the synchronous pulleys, and a synchronous belt is set on the synchronous pulley. The synchronous belt is fixedly connected to the slider. As the synchronous motor reciprocates, the slider drives the slide plate to move back and forth. The lower pressure component is fixedly connected to the top of the slide plate, and a pneumatic suction cup is fixedly connected to the bottom of the lower pressure component. The pneumatic suction cup includes a suction cup body, a suction cup pad, a suction cup base, an air pipe, and a pneumatic control valve. The pneumatic suction cup uses the pressure difference to achieve the purpose of adsorbing the waveguide antenna through the force generated by the gas flow. When the air pressure control unit opens the air source to supply air, the gas enters the small hole of the suction cup body from the air pipe. Since the bottom of the suction cup body is sealed, the gas can only flow out through the opening at the top of the suction cup, thus forming a low-pressure area above the suction cup. At the same time, atmospheric pressure acts on the outside of the suction cup, making the air pressure at the bottom of the suction cup relatively high. Therefore, a pressure difference is created above the suction cup, generating a downward suction force between the suction cup and the object. When the suction cup contacts the object, a sealed space is formed between the object's surface and the gas above the suction cup. At this time, the air pressure above the suction cup is lower than the external air pressure, and the suction force generated by the suction cup can firmly adhere the object to the suction cup. When the air pressure control unit shuts off the air supply, the air pressure above the suction cup becomes equal to the external air pressure, the suction force on the suction cup disappears, and the object detaches from the suction cup. This object is a waveguide antenna, and the suction cup base is fixedly connected to the bottom of the pressing component. The waveguide antenna is then moved back and forth via a linear guide rail assembly.

[0039] The monitoring mechanism includes: a base, a mounting bracket on the base, and a monitoring component disposed on one side of the mounting bracket; both the mounting bracket and the monitoring component are positioned directly below the linear guide rail assembly, and the monitoring component is used to prevent the circuit board from being fixed. This invention provides an automatic alignment system for precisely assembled waveguide antennas.

[0040] In a preferred embodiment of the present invention, the monitoring component includes a monitoring frame and an infrared rangefinder disposed around the monitoring frame, the monitoring frame being used to fix the circuit board.

[0041] It should be noted that an infrared rangefinder is a phase-type photoelectric rangefinder that uses infrared light as its light source. It utilizes the constant speed of infrared light in air to calculate the distance to the object by measuring the time difference between the emitted and received signals. The working principle of an infrared rangefinder is primarily based on the principle of non-divergence during infrared propagation. During operation, infrared light is emitted from the rangefinder, reflected back after hitting a waveguide antenna or circuit board, and then received by the rangefinder. The distance can be calculated based on the time it takes for the infrared light to travel from emission to reception and the speed of infrared propagation. Specifically, the rangefinder's main control oscillator generates a modulation signal frequency, which is amplified and applied to a light-emitting diode (LED). The LED is then modulated by current to emit infrared modulated light. The infrared light exits the emitting optical system, strikes a reflector, and after reflection, is received by the receiving optical system and reaches a photodiode. After photoelectric conversion, a high-frequency ranging signal is obtained. Automated infrared rangefinders also incorporate logic instruction circuits for program control.

[0042] In a preferred embodiment of the present invention, the monitoring frame includes a monitoring platform and support rods disposed around the bottom of the monitoring platform. The support rods are specifically hydraulic rods. The monitoring platform is hollow in the middle and has a placement slot that is the same shape and size as the circuit board. A locking plate is slidably connected to the corner of the monitoring platform and the locking plate can move diagonally on the monitoring platform.

[0043] It should be noted that the monitoring frame includes a monitoring platform and support rods. The support rods are provided with four rods, which are fixedly connected to the four corners of the monitoring platform. The bottom of the support rods is fixedly connected to the base. The support rods are hydraulic rods. As the support rods retract, they drive the monitoring platform to move up and down. The monitoring platform has a placement slot, which is the same shape and size as the circuit board. A locking plate is slidably connected at the corner of the top of the monitoring platform. The locking plate can move along the diagonal of the monitoring platform. During operation, the circuit board is placed in the placement slot, and the locking plate is moved to fix the circuit board in the placement slot.

[0044] An automatic alignment method for precisely assembled waveguide antennas includes the following steps:

[0045] Several waveguide antennas are placed on the mounting rack, and a pneumatic suction cup adsorbs the waveguide antennas. A linear slide rail assembly moves the adsorbed waveguide antennas to the hollow part of the testing platform. The waveguide antennas are then placed on the mounting plate through the hollow part, and the circuit board is placed on the testing platform. The rotating assembly is rotated to adjust the angle of the waveguide antennas, and then the shaking assembly is rotated to adjust the position of the waveguide antennas. At the same time, an infrared rangefinder monitors the position of the waveguide antennas and the circuit board in real time until specific contact points on the two are aligned. After the infrared rangefinder detects that the alignment is complete, the testing platform drives the circuit board to press down, assembling the circuit board and the waveguide antennas.

[0046] In this invention, the rotating component and the wobbling component are used to adjust the angle of the waveguide antenna in two dimensions, respectively.

[0047] It should be noted that the alignment system also includes a main control unit, a sensor module, an execution module, and an interaction module. The main control unit, as the core of the system, is responsible for receiving operation commands, processing sensor data, and coordinating the work of each execution module. The infrared rangefinder in the sensor module monitors the distance between the waveguide antenna and the circuit board in real time, ensuring precise alignment of specific contact points. The execution module includes a pneumatic suction cup, a linear guide rail assembly, a rotating assembly, a shaking assembly, and a testing platform. These components are responsible for adsorbing the waveguide antenna, moving the waveguide antenna to the testing platform, adjusting the angle and position of the waveguide antenna, and the final pressing assembly action, respectively. The human-machine interface module provides an interface between the operator and the control system, allowing the operator to easily control the entire assembly process and monitor the system status in real time. Through this meticulous design and control, the system achieves efficient and precise assembly of the waveguide antenna and the circuit board.

[0048] In use, the linear slide rail assembly moves the pressing component and the pneumatic suction cup to directly above the placement rack, where the waveguide antenna is placed. The pressing component then presses down, moving the pneumatic suction cup above the waveguide antenna and into contact with it, adsorbing the antenna. The pressing component then moves upward, moving the waveguide antenna above the monitoring platform via the linear slide rail assembly. The waveguide antenna is placed on the placement plate through the hollow area above the monitoring platform. The rotating assembly then rotates, causing the bending plate to rotate. Simultaneously, the bending plate slides against the short shaft, which in turn rotates the connecting shaft and the placement plate, thus rotating the waveguide antenna on the placement plate. This ensures that the angle between the waveguide antenna and the specific contact point on the circuit board is aligned. During rotation, the adjustment mechanism uses two sets of worm gears for combined adjustment. Only the worm gear drives the worm wheel during rotation, and the rotating assembly also drives the meshing bevel gear, causing an angular shift in the placement plate. During the rotation, the shaking component also rotates to resist this offset, keeping the placement plate horizontal. After the waveguide antenna is aligned with the specific contact point on the circuit board, the shaking component shakes back and forth, causing the waveguide antenna to slide down and align with the specific contact point on the circuit board. The adjustment of the angle and alignment are monitored in real time by an infrared rangefinder to avoid deviation. Then the support rod is pressed down, connecting the waveguide antenna to the specific contact point on the circuit board via a snap-fit ​​connector.

[0049] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
