Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a calibration mechanism and line calibration equipment. Background Technology

[0002] In the wire and cable industry, an antenna generally refers to a device used for wireless communication, transmitting and receiving electromagnetic waves. It mainly consists of a conductor (such as copper or aluminum wire), an insulation layer, and a sheath, used to transmit electrical energy or signals. There are many types of antennas, including but not limited to communication antennas, broadcast television antennas, and radar antennas, each with its specific application scenarios and performance requirements.

[0003] In related technologies, antenna production typically involves pre-processing steps including, but not limited to, wire feeding, bending correction, length correction, and angle correction. After completing these pre-processing steps, the wire enters the welding process to realize the production line stage. Because the wire substrate is a flexible material, wire bending and unevenness at each wire end can occur. During the welding process, the welding points of the laser equipment cannot automatically align with the wire pads, resulting in the welding position deviating from the pads. Utility Model Content

[0006] The pusher assembly is configured to receive the wire and push the end of the wire flat.

[0007] The transfer component is configured to convey the flattened wire in the pusher component to the wire adjustment component;

[0008] The wire adjustment assembly is configured to limit the wire and rotate the wire to a preset angle.

[0009] In one embodiment of the present invention, the wire pushing assembly includes a limiting member and a wire pushing plate. The limiting member has a limiting cavity, the extending direction of the limiting cavity is arranged in a first straight line direction, and is configured to limit the wire. The wire pushing plate is movable toward or away from the limiting cavity and is configured to flatten the end of the wire.

[0010] In one embodiment of the present invention, the limiting member includes two first limiting segments and at least one second limiting segment. The two first limiting segments are aligned along the first straight line direction. The second limiting segment is located between the two first limiting segments. The length of the second limiting segment along the first straight line direction is greater than the length of the first limiting segment. The pusher plate is disposed on the side of any first limiting segment facing away from the second limiting segment.

[0011] In one embodiment of the present invention, each limiting segment is provided with a limiting groove, and the cross-sectional area of ​​each limiting groove gradually decreases along the direction from the groove opening to the groove bottom; each limiting groove aligned along the first straight line direction forms the limiting cavity.

[0012] In one embodiment of this utility model, each of the limiting grooves is a wedge-shaped groove.

[0013] In one embodiment of the present invention, the wire adjustment assembly has a rotating cavity and a rotating gripper, the rotating gripper being disposed directly opposite the rotating cavity; the rotating cavity extends along a second straight line and is configured to receive the wire from the transfer assembly and limit the wire, the rotating gripper being configured to clamp and rotate the wire in the rotating cavity to a preset angle.

[0014] In one embodiment of the present invention, the wire adjustment assembly is provided with a straightening module, the straightening module includes a plurality of first limiting arms and a plurality of second limiting arms, the plurality of first limiting arms and the plurality of second limiting arms are alternately arranged along a second straight line direction, and the first limiting arms are arranged to move closer to or further away from the second limiting arms.

[0015] Each limiting arm has an arc-shaped notch. When the first limiting arm moves close to the second limiting arm, the multiple arc-shaped notches along the second straight line direction form the rotating cavity.

[0016] In one embodiment of the present invention, the straightening module further includes a first moving plate and a second moving plate, each of the first limiting arms is disposed on the first moving plate, and each of the second moving plates is disposed on the second moving plate, wherein the first moving plate is disposed close to or away from the second moving plate.

[0033] The main purpose of this invention is to provide a calibration mechanism 100, which aims to adjust the position of the antenna before it enters the welding process, so as to ensure the welding effect of the antenna during welding.

[0034] To resolve the above issues, please refer to [link / reference]. Figure 1 The calibration mechanism 100 includes a wire pushing assembly 10, a transfer assembly 20, and a wire adjusting assembly 30, with the transfer assembly 20 located between the wire pushing assembly 10 and the wire adjusting assembly 30.

[0035] The wire pusher assembly 10 is configured to receive the wire and push the end of the wire flat;

[0036] The transfer component 20 is configured to convey the flattened wire in the wire pusher component 10 to the wire adjusting component 30;

[0037] The wire adjustment assembly 30 is configured to limit the wire and rotate the wire to a preset angle.

[0038] In this utility model's technical solution, the calibration mechanism 100 straightens and rotates the wire to a preset angle. The calibration mechanism 100 includes a wire pushing assembly 10, a transfer assembly 20, and a wire adjusting assembly 30. The transfer assembly 20 is located between the wire pushing assembly 10 and the wire adjusting assembly 30. When the wire is placed into the wire pushing assembly 10 by a robotic arm or manually, the wire pushing assembly 10 applies a pushing force to the ends of each wire to make the ends of each wire flush. Subsequently, the transfer assembly 20 transports each wire to the wire adjusting assembly 30. The wire adjusting assembly 30 first... First, straighten each wire to prevent bending of wires made of flexible materials. Then, rotate the wire to the required preset angle. In this way, before entering the next process, each wire remains straight while the angle between the terminal structure at its end and the horizontal plane is at the required angle. Through the calibration mechanism 100, the need for manual intervention during the production process can be reduced, production efficiency can be improved, and the solder joints of each wire can be accurately aligned with the solder pads, thereby achieving a highly automated and reliable soldering process and significantly reducing the risk of soldering defects.

[0039] In one embodiment, the wire pushing assembly 10 includes a hydraulic cylinder, a wire pushing plate 12, a limiting member 11, and a hydraulic control system electrically connected to the hydraulic cylinder. The wire pushing plate 12 is fixedly connected to the piston rod of the hydraulic cylinder. The limiting member 11 is positioned opposite the wire pushing plate 12 and has multiple limiting grooves 11a, each capable of limiting and accommodating one wire. The hydraulic control system drives the extension and retraction of the piston rod of the hydraulic cylinder. The hydraulic cylinder, as the core power component, has its cylinder body fixed to the base of the wire straightening module via sheet metal parts and locking components. The size of the wire pushing plate 12 is adapted to the limiting member 11, and the material of the wire pushing plate 12 is an engineering plastic with moderate hardness. This design ensures sufficient pushing force on the wires without damaging the wire terminals. The guide groove can be U-shaped or V-shaped, allowing the groove wall to guide the wires into the bottom of the guide groove. This ensures that the spacing between multiple wires in a group located in the limiting member 11 is the same or within a reasonable error range, facilitating the transfer component 20 to accurately pick up multiple wires each time. Under the control of the hydraulic control system, the hydraulic cylinder can drive the push plate 12 to move towards the limiting member 11, thereby aligning the ends of each wire in the group of wires in the limiting member 11. This ensures that after each wire enters the wire adjustment component 30, the ends of each wire are in the same position.

[0040] The transfer assembly 20 includes a moving guide rail and a vacuum adsorption module mounted on the moving guide rail. The vacuum adsorption module is connected to the moving guide rail via a fixing plate, locking components, and other structures. Driven by a cylinder, linear motor, and other driving components, the vacuum adsorption module can move towards or away from the limiting component 11 in the vertical direction. The moving guide rail can drive the vacuum adsorption module to move towards or away from the limiting component 11 in the horizontal direction, thereby realizing the transfer of the wire to the wire adjustment assembly 30. The vacuum adsorption module includes a vacuum adsorption unit and multiple air nozzles. Under the action of the vacuum adsorption unit, the air nozzles can generate negative pressure. When each air nozzle contacts a wire, the air nozzle can adsorb and fix the wire through the negative pressure, thereby realizing the transfer of the wire from the wire pushing assembly 10 to the wire adjustment assembly 30. Furthermore, because the wire is flexible, each air nozzle has multiple air holes that generate negative pressure. The multiple air holes are spaced apart, so that each air nozzle can adsorb different positions of the wire, thereby ensuring the wire is transferred. During transport, the wire remains straight to prevent bending under gravity. This ensures that when the wire is placed into the wire adjusting assembly 30, the wire will not be misaligned due to different deformations at both ends caused by the need to straighten it further. In another embodiment, the transfer assembly 20 is a robotic arm structure with multiple joints, including a base joint, upper arm joint, lower arm joint, and end effector joint. Each joint is driven by a servo motor and equipped with a high-precision reducer for precise position control. The end effector of the robotic arm is a wire gripper, which can be a pneumatic or electric gripper. A pneumatic gripper uses compressed air to control its opening and closing, while an electric gripper uses a motor-driven screw mechanism. After the wire pushing assembly 10 flattens the wire end, the control system drives the gripper at the end of the robotic arm to move accurately above the wire, gripping it. The robotic arm then moves the wire to the position of the wire adjusting assembly 30 according to a preset motion path. During the movement, the angle sensor provides real-time feedback on the joint angle information, and the controller adjusts the joint movement based on this information to ensure the smooth movement of the wire. After the robotic arm reaches the position, the gripper releases the wire, and the wire is placed in the appropriate position of the wire adjustment component 30, thereby realizing the wire transfer.

[0041] The wire adjustment assembly 30 includes a straightening module 31 for accommodating the wire and a rotating module 32 for rotating the wire. The transfer assembly 20 places the wire into the straightening module 31 and constrains it. The rotating module 32 clamps the end of the wire and rotates it. In one embodiment, the wire adjustment assembly 30 includes a fixing clamp, a wire rotating device, and an angle measuring device. The fixing clamp is used to clamp the wire and consists of two openable clamping plates. The two clamping plates open and close to accommodate and limit the wire. The inner side of the clamping plates is provided with a rubber pad to increase the friction between the clamp and the wire and prevent the wire from slipping during adjustment. The opening and closing of the clamp is controlled by a handle or a pneumatic component. It can quickly clamp and release wires; the wire rotation device includes a rotating shaft and a rotating motor. The rotating motor is connected to the rotating shaft through a coupling. The gripper is connected to the rotating shaft of the rotating motor. The drive signal of the motor is provided by the controller. The rotating motor can be a stepper motor or a servo motor, which can accurately control the rotation angle, and is not limited here; the angle measuring device is an encoder, which is installed on the rotating shaft. By measuring the rotation angle of the rotating shaft, the angle information is fed back to the controller. When the wire is conveyed to the position of the wire adjustment component 30 through the transfer component 20, the fixing clamp clamps one end of the wire, and the rotating motor starts to work according to the command of the controller, driving the rotating shaft to rotate. When the rotating shaft rotates, the wire rotates accordingly. The encoder measures the angle of the rotating shaft in real time and feeds the angle information back to the controller. The controller determines whether the wire has rotated to the preset angle based on the feedback angle information. It can be understood that vision devices such as industrial cameras first obtain the real-time angle of the wire before correction. Based on the deviation angle between the real-time angle and the preset angle, the controller controls the rotation direction (such as forward or reverse rotation) and rotation angle of the rotating motor through the deviation angle information, so that the wire can accurately enter the preset angle and prepare for the next step of the work.

[0042] In some embodiments, please refer to Figure 2The wire pushing assembly 10 includes a limiting member 11 and a wire pushing plate 12. The limiting member 11 has a limiting cavity 10a, which extends in a first linear direction and is configured to limit the wire. The wire pushing plate 12 is movable toward or away from the limiting cavity 10a and is configured to flatten the end of the wire. Specifically, the limiting member 11 is an elongated component with a limiting cavity 10a inside. The size of the limiting cavity 10a matches the cross-sectional shape and size of the wire, enabling it to stably accommodate the wire. Simultaneously, the extending direction of the limiting cavity 10a is in the first linear direction, allowing the wire to be initially straightened after falling into the groove. The wire pushing plate 12 is a rectangular plate structure whose moving direction is parallel to the extending direction of the limiting cavity 10a. The wire pushing plate 12 is driven by a linear motor. When the wire is placed in the limiting cavity 10a, the control system of the linear motor is activated. The control system sends a drive signal, causing the mover of the linear motor to move along the stator direction. The movement of the mover causes the pusher plate 12 to move toward the limiting cavity 10a. After the pusher plate 12 contacts the end of the wire, it continues to apply a pushing force to flatten the end of the wire. Since the linear motor can precisely control the moving distance and speed, the position of the pusher plate 12 can be quickly and accurately adjusted according to the initial state of the wire and the target flattening degree, so that the end of the wire reaches a flush state. When the set flattening position is reached, the control system stops the linear motor and keeps the pusher plate 12 in that position for subsequent transfer operations.

[0043] Further, please refer to Figure 2The limiting member 11 includes two first limiting segments 111 and at least one second limiting segment 112. The two first limiting segments 111 are aligned along a first straight line direction. The second limiting segment 112 is located between the two first limiting segments 111. The length of the second limiting segment 112 along the first straight line direction is greater than the length of the first limiting segment 111. The push plate 12 is disposed on the side of any first limiting segment 111 facing away from the second limiting segment 112. In one embodiment, the limiting member 11 includes two first limiting segments 111 and one second limiting segment 112. The limiting segment 112 is used to support the middle section of the wire body, and the two first limiting segments 111 support the two ends of the wire body respectively. The limiting member 11 can be made of plastic or metal. This segmented support method for the wire saves material when the limiting member 11 is injection molded. Furthermore, the length of the second limiting segment 112 along the first straight line is greater than the length of the first limiting segment 111, ensuring that the wire body will not "collapse." In another embodiment, the limiting member 11 can be made of plastic or metal. Each first limiting segment 111 is detachably configured, and a second limiting segment 112 is spaced apart from the two first limiting segments 111. Thus, by detaching and assembling the first limiting segments 111, the total length of the limiting cavity 10a composed of the three limiting segments can be adjusted, allowing one limiting member 11 to adapt to wires of different lengths. In another embodiment, the limiting member 11 includes two first limiting segments 111 and two second limiting segments 112, which are arranged sequentially and spaced apart along a straight line. Each second limiting segment... The length of each segment 112 is greater than the length of any second limiting segment 112. Thus, when dealing with a large wire terminal, the wire terminal can be placed in the second limiting segment 112 located at the end. At the same time, the push plate 12 is set at the end near the limiting member where the second limiting segment 112 is located. Thus, the push plate 12 abuts against the wire terminal, and the wire terminal is limited by the second limiting segment 112. Meanwhile, the wire has room to move in the first limiting segment 111, thereby ensuring that the wire will not bend or shift when it is pushed flat.

[0044] For compatibility with wires of different diameters, please refer to [link / reference]. Figure 2Each limiting segment is provided with a limiting groove 11a. The cross-sectional area of ​​each limiting groove 11a gradually decreases from the groove opening to the bottom of the groove. The limiting grooves 11a aligned along the first straight line form a limiting cavity 10a. In one embodiment, the limiting groove 11a is an arc-shaped groove. When a small-diameter wire enters the limiting groove 11a, the wire will move along the groove wall of the limiting groove 11a to the bottom of the groove because the cross-sectional area of ​​the limiting groove 11a gradually decreases from the groove opening to the bottom of the groove, thereby being limited and fixed. For a large-diameter wire, it will contact the side wall near the groove opening when it enters the limiting groove 11a. As the cross-sectional area of ​​the limiting groove 11a gradually decreases, large-diameter wires can be effectively limited in the area near the groove opening, preventing the wires from exceeding the range of the limiting groove 11a and ensuring that the wires are reliably supported and fixed within the limiting member 11. At the same time, the large groove opening facilitates the free end of the transfer component 20 to extend into the groove, avoiding contact between the transfer component 20 and the groove wall, thus preventing problems such as impact and motion interference.

[0045] In another embodiment, please refer to Figure 2 Each limiting groove 11a is a wedge-shaped groove. After the wire is placed in the groove, it can be guided to the bottom of the groove by the groove wall. Simultaneously, the two sides of the bottom of the groove restrict the movement of the wire. Thus, when the pusher plate 12 applies a pushing force to the limiting groove 11a, bending of the wire can be prevented. It is understood that when the transfer assembly 20 grips or absorbs the wire, it needs to ensure that the position of its free end above the wire is aligned with the wire's position. The position of the limiting member 11 remains fixed. Therefore, it is only necessary to ensure that the far end of the transfer assembly 20 is aligned with the bottom area of ​​the limiting groove 11a. Based on this, the cross-sectional area of ​​the wedge-shaped groove gradually decreases from the groove opening to the bottom. Only the positional accuracy of the bottom of each limiting groove 11a on the limiting member 11 is needed to ensure the positional accuracy of the wire and the free end of the transfer assembly 20. This reduces the processing requirements of the limiting groove 11a.

[0046] In one embodiment of this utility model, please refer to Figure 3The wire adjustment assembly 30 has a rotating cavity 30a and a rotating gripper 322, with the rotating gripper 322 positioned directly opposite the rotating cavity 30a. The rotating cavity 30a extends along a second straight line and is configured to receive and limit the wire from the transfer assembly 20. The rotating gripper 322 is configured to clamp and rotate the wire in the rotating cavity 30a to a preset angle. The inner diameter of the rotating cavity 30a is larger than the outer diameter of the wire, ensuring that the wire can rotate within the rotating cavity 30a. The rotating cavity 30a extends along a second straight line; this second straight line refers to a straight line that straightens the wire and parallels the horizontal plane. The extension direction can form any angle with any outer side of the frame of the calibration equipment, and there is no need to limit it here; after the transfer component 20 puts the wire into the rotating cavity 30a, the rotating gripper 322 moves forward a certain distance to clamp the wire and expose the end of the rotating cavity 30a. In this process, since the wire is first flattened by the wire pushing component 10, the fixed forward movement distance of the rotating gripper 322 can be obtained according to the movement path of the transfer component 20 and the positional relationship between the limiting cavity 10a and the rotating cavity 30a. In this way, there is no need to set up a vision camera near the rotating gripper 322 to obtain the position of the wire terminal and to control the forward movement distance of the rotating gripper 322, thus reducing the dependence on the control system and the design difficulty.

[0047] Specifically, the wire adjustment assembly 30 is provided with a straightening module 31, which includes multiple first limiting arms 311 and multiple second limiting arms 312. The multiple first limiting arms 311 and multiple second limiting arms 312 are alternately arranged along a second straight line direction, and the first limiting arms 311 are arranged to move closer to or further away from the second limiting arms 312. Each limiting arm has an arc-shaped notch. When the first limiting arm 311 moves closer to the second limiting arm 312, the multiple arc-shaped notches along the second straight line direction form a rotating cavity 30a. The first limiting arms 311 and the second limiting arms 312 achieve linear movement through a drive component 321 such as a motor or cylinder. Thus, the opening of the rotating cavity 30a is achieved by the first limiting arms 311 and the second limiting arms 312 through translational opening and closing. After the arc-shaped notches approach and enclose to form the rotating cavity 30a, the inner surface of its top... As a stop wall, when the wire rotates in the rotating cavity 30a, because the end of the wire away from the rotating gripper 322 is not constrained, there is a problem of the wire being twisted by torque. When the wire is twisted, there is an up-and-down swing phenomenon, which causes "jumping". The stop wall of the rotating cavity 30a can stop the wire from jumping, thereby improving the stability of the wire when it rotates. At the same time, multiple first limiting arms 311 and multiple second limiting arms 312 are alternately arranged along the second straight line direction. That is, along the second straight line direction, any two adjacent arc-shaped notches are staggered. In this way, by changing the distance between the first limiting arms 311 and multiple second limiting arms 312 when they move towards each other, the inner diameter of the rotating cavity 30a can be changed, thereby achieving the locking of wires of different diameters, thus realizing the straightening function of a straightening module 31 for wires of different diameters.

[0048] In one embodiment, please refer to Figure 3The straightening module 31 also includes a first movable plate 313 and a second movable plate 314. Each first limiting arm 311 is disposed on the first movable plate 313, and each second movable plate 314 is disposed on the second movable plate 314. The first movable plate 313 is positioned close to or away from the second movable plate 314. Specifically, the straightening module 31 is provided with a limiting plate 315, which is supported by a support rod to maintain a certain distance between the limiting plate 315 and the base surface of the alignment module. The limiting plate 315 has multiple spaced-apart... The limiting parts are designed such that any two adjacent limiting parts are hollowed out to form a movable channel, which connects the space between the limiting plate 315 and the base surface. The first movable plate 313 and the second movable plate 314 are both located on the side of the limiting plate 315 facing the base surface. The first limiting arm 311 and the second limiting wall pass through the movable channel and are exposed on the surface of the limiting plate 315. Simultaneously, each limiting part is provided with a wedge-shaped groove, the bottom of which and the bottom of each arc-shaped notch are set at the same height relative to the horizontal plane, allowing for... Under the drive of cylinders, motors, and other driving components, the first moving plate 313 and the second moving plate 314 can move in opposite directions and in opposite directions. When the wire is above the wedge-shaped groove of the limiting part, the two moving plates can be driven to move in opposite directions simultaneously, or the two moving plates can be driven to move in opposite directions in advance, which is not limited here. Then the wire first falls into the wedge-shaped groove of the limiting part. Under the guidance of the groove wall and the action of gravity, the wire can fall to the bottom of the groove. Because the bottom of the wedge-shaped groove and the bottom of each arc-shaped notch are set at the same height, the wire can be covered when the arc-shaped notch is closed, thus straightening the wire. In this process, the linear motion of the first moving plate 313 and the second moving plate 314 is the same as the motion of the first limiting arm 311 and the second limiting arm 312. There is no need to convert the motion form through a motion conversion structure, which simplifies the motion process. At the same time, the motion of multiple limiting arms can be controlled by only controlling the movement of the moving plates, reducing the control process and thus reducing the design difficulty of the control program and circuit system.

[0049] In one embodiment, please refer to Figure 3The wire adjustment assembly 30 also includes a rotation module 32, which includes a drive unit 321, a rotating gripper 322, and a positioning camera. The rotating gripper 322 is connected to the rotation output shaft of the drive unit 321, and the positioning camera is electrically connected to the drive unit 321. The positioning camera is configured to drive the drive unit 321 to rotate the rotating gripper 322 according to the real-time position of the wire. Specifically, after the wire is placed in the rotation cavity 30a, the positioning camera first identifies and positions the initial position of the wire. Based on the deviation between the current position of the wire and the preset target position, the positioning camera calculates the required rotation angle and direction and sends the corresponding control signal to the drive unit 321. After receiving the signal, the drive unit 321 precisely controls the rotation of the rotating gripper 322, causing the gripper to rotate the wire to the preset angle. Throughout the process, the positioning camera continuously monitors the position of the wire, ensuring that the rotating gripper 322 is adjusted according to the predetermined angle and direction until the wire reaches the required precise position. Furthermore, a viewing glass is provided between the positioning camera and the limiting cavity 10a. The viewing glass is fixed to the side of the limiting cavity 10a facing the positioning camera by a support member. The viewing glass allows the positioning camera to see through to the terminal of the wire. The viewing glass can be coated with an optical coating to reduce the reflection and refraction of light, thereby improving the clarity and accuracy of the image.

[0050] This utility model also proposes a wire calibration device, which mainly includes a frame, linear guide rails, a wire feeding mechanism, a tray unloading mechanism, a wire picking mechanism, a calibration mechanism 100, and a pre-processing mechanism. The frame, as the basic component of the entire calibration device, provides a stable mounting platform for the other mechanisms. The wire feeding mechanism is responsible for conveying the tray containing wire material to the working position of the wire picking mechanism. It supports manual feeding, where operators place the stacked trays into the wire feeding mechanism, and also supports automated feeding via robotic arms, achieving an automated feeding process. The material tray unloading mechanism is used to remove the empty material tray or the tray with remaining material from the working area after the wire is picked up, so as to facilitate subsequent processing. The wire picking mechanism transports the material in the tray to the calibration mechanism 100 through vacuum adsorption in the working position, and performs the wire straightening, angle correction and other operations required before welding. Then the wire is transferred to the pre-processing mechanism to lock the wire. The specific structure of the calibration mechanism 100 is as described in the above embodiment. Since the wire calibration equipment proposed in this utility model adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.

[0051] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
