Description

Technical Field

[0001] The present invention relates to the technical field of probe welding, and particularly relates to a probe welding device for microwave module production. Background Art

[0002] Microwave modules play a key role in radar systems. They are used to manufacture high-performance radar devices, such as digital array radars, which are widely applied to various platforms such as airborne, shipborne, missile-borne, ground-fixed, and vehicle-mounted platforms. These radar systems are involved in multiple fields such as communication, countermeasure, navigation, and command automation.

[0003] The microwave in a microwave radar module is a radio wave with a very short wavelength. The microwave has a good directivity and its speed is equal to the speed of light. When the microwave encounters a vehicle, it is immediately reflected back and then received by the radar speedometer. In such a to-and-fro process, within just a few hundred-thousandths of a second, the vehicle speed measured will be displayed on the digital tube. Radar or microwave is a kind of electric wave emitted by a transmitter similar to a radio, except that its frequency is much higher. When a person or an object moves within the induction range of the microwave, the inductor will be activated.

[0004] When a microwave radar module is in production and use, it is necessary to weld the probe in the microwave radar to a connecting wire.

[0005] The existing welding devices have the following deficiencies: 1. Since the probe size is small, during the process of welding the connecting wire to the probe, manual operation is rather difficult, and it is impossible to achieve precise positioning of the probe and the connecting wire, which increases the welding difficulty.

[0006] 2. For microwave modules of different sizes, the spacing between several probes on their outer walls is different. The existing welding devices cannot flexibly adjust the clamping spacing of the connecting wire according to the spacing between several probes, which reduces the welding efficiency, and the practicability and flexibility of the device need to be improved.

[0007] 3. When the sizes of the microwave module or the connecting wire change, if the same fixture is used to position the two, it is easy to make the distance between the connecting wire and the probe too large, resulting in virtual welding or welding misalignment, and reducing the welding quality of the two.

[0019] Advantages of the present invention: 1.

There is no need to manually hold the connecting line and the probe for welding, avoiding the welding problem caused by the inaccurate positioning of the two due to the small size of the probe, greatly reducing the welding difficulty, and thus improving the welding effect and welding efficiency.

[0020] 2. By designing a variable pitch mechanism, namely an adjusting plate, a driving assembly, and several sliding plates, the present invention can drive the adjusting plate to slide horizontally through the driving assembly, so as to realize the mutual separation or mutual approach of several sliding plates and the positioning plates thereon, realize the variable pitch of several connecting lines, and thus facilitate the alignment with several probes on microwave modules of different sizes. At the same time, by designing a rotating assembly, the two clamping plates can be driven to approach or separate from each other to meet the clamping requirements for microwave modules of different sizes, and further meet the welding requirements for several probes and several connecting lines of microwave modules of different size specifications, improving the flexibility of the device.

[0021] 3. The present invention designs a second lead screw, a micro-motor, a lifting block, a mounting rod, a sliding strip and a sliding groove of a lapping plate. When the size of the microwave module changes, the height of the probe may change. Through the cooperation of the above structures, the lapping plate can be driven to vertically lift until the probe is driven to rise to a suitable welding distance from the connecting wire, which is convenient for quick welding, avoids virtual soldering or welding misalignment caused by too large a distance between the connecting wire and the probe, and is beneficial to improving the welding quality between the probe and the connecting wire of the microwave module.

[0022] 4. The present invention designs a positioning mechanism, namely a plurality of positioning plates and a plurality of locking components. Each positioning plate is used to place a connecting wire, and each locking component is designed as an elastic locking structure. When loading the connecting wire, only need to horizontally place the connecting wire on the tops of a plurality of wedge-shaped buckles, and then slightly press the outer wall of the connecting wire. The contraction of a plurality of pressing springs drives the contraction of a plurality of sliding rods into the insertion holes, thereby driving the plurality of wedge-shaped buckles to move away from each other, facilitating the insertion of the connecting wire into the V-shaped receiving groove at the top of the positioning plate. Then the worker releases the hand, and under the reset action of the plurality of pressing springs, the plurality of wedge-shaped buckles are reset, and the outer wall of the connecting wire is pressed by the hypotenuse on the wedge-shaped buckle to achieve locking. When the welding is completed, due to the elastic locking structure designed, the connecting wire can be directly pulled out from the V-shaped receiving groove manually, which not only meets the positioning of the connecting wire, but also improves the loading and unloading efficiency of the connecting wire, reduces the overall welding time of the microwave module, and thus is beneficial to improving the welding efficiency.

[0023] 5. The present invention designs a V-shaped receiving groove, which is designed with a structure that is wider at the top and narrower at the bottom, and can accommodate connecting wires with different diameters, so as to meet the positioning requirements of connecting wires with different size specifications, and thus is convenient for welding with the probes on microwave modules with different size specifications, improving the practicability of the device.

[0024] 6. The present invention designs each positioning plate to be bolted to a sliding plate. When the positioning plate is damaged, it can be replaced individually without discarding the entire positioning mechanism, avoiding waste, being beneficial to reducing the welding cost of the microwave module, and thus improving the maintenance efficiency of the device and being beneficial to reducing the maintenance cost of the device.

The plurality of sliding plates 12 are arranged at equal intervals on the top of the installation plate 13; The positioning mechanism is arranged on the pitch-changing mechanism. The positioning mechanism includes a plurality of positioning plates 14 and a plurality of locking components. Each positioning plate 14 is fixedly arranged on the outer wall of a sliding plate 12 through bolts. The plurality of locking components are respectively arranged on the tops of the plurality of positioning plates 14; The clamping mechanism is arranged on the top of the welding table 10. The clamping mechanism includes an electric control component, a rotating component and two clamping plates 15. An installation table is fixedly arranged on the top of the welding table 10. The electric control component is arranged on the installation table. The rotating component is arranged on the electric control component. The two clamping plates 15 are symmetrically arranged on the top of the installation table; The welding mechanism is arranged on the top of the welding table 10. The welding mechanism includes a welding head 16 and a position adjusting component. An L-shaped plate is fixedly arranged on the top of the welding table 10. The position adjusting component is arranged on the top of the L-shaped plate. The welding head 16 is fixedly arranged on the position adjusting component.

[0030] Refer to Figures 1 to 12 As shown, the driving component includes a stepping motor 17, a synchronous belt 18, a first lead screw 19 and two synchronous pulleys 20. The stepping motor 17 is fixedly arranged on the top of the installation plate 13. The two synchronous pulleys 20 are respectively fixedly arranged at one end of the first lead screw 19 and the output end of the stepping motor 17. The first lead screw 19 is rotatably arranged on the outer wall of the installation plate 13 through two limiting plates. A moving block 21 is fixedly arranged on the top of the adjusting plate 11. The first lead screw 19 is threadedly connected with the moving block 21. The synchronous belt 18 is sleeved between the two synchronous pulleys 20. When the size of the microwave module 56 to be processed increases, the pitch of all the probes 54 on the microwave module 56 will also increase synchronously. Therefore, the pitch of the connecting wires 55 welded to all the probes 54 also needs to increase synchronously. At this time, it is necessary to synchronously increase the pitch of the plurality of sliding plates 12 and the plurality of positioning plates 14 to meet the positioning requirements of the plurality of connecting wires 55 with different pitches. Therefore, the stepping motor 17 is started through the controller, so that its output end drives one of the synchronous pulleys 20 to rotate. Since the other synchronous pulley 20 is fixedly connected with the first lead screw 19, the two synchronous pulleys 20 are sleeved through the synchronous belt 18, the moving block 21 is fixedly connected with the adjusting plate 11, the moving block 21 is threadedly connected with the first lead screw 19, and the adjusting plate 11 is slidably connected with the installation plate 13, thereby driving the adjusting plate 11 to horizontally slide towards the end close to the L-shaped plate.

[0031] Refer to Figures 1 to 12As shown in the figure, two guide rails 22 are symmetrically arranged at the top of the mounting plate 13. The adjusting plate 11 is slidably connected to the two guide rails 22. Four guide blocks 23 are arranged at equal intervals between the two guide rails 22. A number of sliding plates 12 are slidably connected to the four guide blocks 23. A traction rod 24 is fixedly provided at the top of each sliding plate 12. An avoidance groove for the sliding of a number of traction rods 24 is provided on the outer wall of the adjusting plate 11. When the adjusting plate 11 slides horizontally towards the end close to the L-shaped plate, since the adjusting plate 11 is slidably connected to the two guide rails 22, four guide blocks 23 are arranged at equal intervals between the two guide rails 22, a number of sliding plates 12 are slidably connected to the four guide blocks 23, each sliding plate 12 is fixedly connected to a traction rod 24, and an avoidance groove for the sliding of a number of traction rods 24 is designed on the outer wall of the adjusting plate 11, and the avoidance groove is inclined. Therefore, when moving towards the end close to the L-shaped plate through a number of avoidance grooves, the resistance force generated on a number of traction rods 24 drives a number of sliding plates 12 and the positioning plate 14 to move away from each other, that is, the distance between every two adjacent positioning plates 14 is increased, meeting the alignment requirements of a number of connection lines 55 and a number of probes 54 on the outer wall of a microwave module 56 with a larger size, facilitating quick welding.

[0032] Refer to Figures 1 to 12 As shown in the figure, the electric control assembly includes a servo motor 25, a driving wheel 26, a driven wheel 27, a rotating shaft 28 and a first belt 29. The servo motor 25 is fixedly arranged at the top of the mounting table. The driving wheel 26 is fixedly arranged on its output end. The rotating shaft 28 is rotatably arranged at the top of the mounting table. The driven wheel 27 is fixedly arranged on the rotating shaft 28. The first belt 29 is sleeved between the driving wheel 26 and the driven wheel 27. This device is equipped with a controller, and all the electrical devices on the device are electrically connected to the controller. After a number of connection lines 55 are horizontally placed into the internal of a number of V-shaped receiving grooves 46 in the positioning, first, manually grasp the microwave module 56 to make it horizontally suspended between the two clamping plates 15, and then start the servo motor 25 through the controller, so that its output end rotates. Since its output end is fixedly connected to the driving wheel 26, the driven wheel 27 is fixedly connected to the rotating shaft 28, the rotating shaft 28 is rotatably connected to the mounting table, and the driving wheel 26 and the driven wheel 27 are sleeved through the first belt 29, the rotating shaft 28 is driven to rotate slowly.

[0033] Refer to Figures 1 to 12As shown in the figure, four slide rails are fixedly arranged on the top of the installation table. A sliding column 30 is slidably arranged on the top of each slide rail. Each clamping plate 15 is fixedly arranged between the tops of every two sliding columns 30. The rotating assembly includes a turntable 31 and two connecting rods 32. The turntable 31 is fixedly arranged on the rotating shaft 28. One end of each connecting rod 32 is hinged between the turntable 31 and a clamping plate 15. When the rotating shaft 28 rotates slowly, since each sliding column 30 is slidably connected to a slide rail, each clamping plate 15 is fixedly connected to the tops of every two sliding columns 30, the rotating shaft 28 is fixedly connected to the turntable 31, and one end of the turntable 31 and each clamping plate 15 are hinged to both ends of a connecting rod 32, the two clamping plates 15 slowly approach each other, clamping both ends of the microwave module 56. By designing the rotating assembly, the two clamping plates 15 can be driven to approach or move away from each other, meeting the clamping requirements for microwave modules 56 of different sizes, and further meeting the soldering requirements for the probes 54 of microwave modules 56 of different size specifications, improving the practicability of the device.

[0034] Refer to Figures 1 to 12 As shown in the figure, two support plates 33 are fixedly arranged on the outer wall of each clamping plate 15. When the two clamping plates 15 clamp both ends of the microwave module 56, the two support plates 33 at the top of each clamping plate 15 support the bottom end of the microwave module 56, further improving the clamping stability of the microwave module 56 and being beneficial to improving the soldering effect with the connecting wire 55. Since the designed height of the support plate 33 is lower than the designed height of the V-shaped receiving groove 46, all the probes 54 of the clamped microwave module 56 are exactly located directly below all the connecting wires 55.

[0035] Refer to Figures 1 to 12As shown, the position adjustment assembly includes an electric slide table 34, a cylinder 35, a first slider 36, an L-shaped block 37, and a second slider 38. The electric slide table 34 is fixedly arranged on the top of the L-shaped plate. The first slider 36 is slidably arranged on the outer wall of the electric slide table 34. The L-shaped block 37 is fixedly arranged on the outer wall of the first slider 36. A slideway 39 is fixedly arranged on the outer wall of the L-shaped block 37.

When all the probes 54 on the microwave module 56 are pushed up to be in close contact with all the connecting wires 55, the first slider 36 is driven to slide horizontally by the electric slide table 34. Since the first slider 36 is fixedly connected to the slideway 39 through the L-shaped block 37, the cylinder 35 is inserted into the L-shaped block 37, its output end is fixedly connected to the mounting block 40, the welding head 16 is fixedly connected to the second slider 38 through the mounting block 40, and the second slider 38 is slidably connected to the slideway 39, the welding head 16 is driven to slide horizontally to directly above the first connecting wire 55 by the first slider 36. Then, the cylinder 35 is started by the controller, and its output end drives the mounting block 40 and the welding head 16 thereon to descend, welding the first connecting wire 55 and the first probe 54 together. Then, the welding head 16 is driven to rise by the cylinder 35, and the welding head 16 is driven to move horizontally to directly above the second connecting wire 55 by the first slider 36 on the electric slide table 34. According to the above welding steps, the welding work of the remaining connecting wires 55 and probes 54 is realized.

[0036] Refer to Figures 1 to 12As shown, each locking assembly includes a wedge-shaped buckle 41, a slide bar 42 and two holding springs 43. Six grooves are symmetrically arranged on the top of the positioning plate 14. A socket is provided at one end of each groove. The slide bar 42 is slidably arranged inside one of the sockets. The wedge-shaped buckle 41 is fixed at the end of the slide bar 42 away from the socket. Each holding spring 43 is fixed between the wedge-shaped buckle 41 and the inner wall of the groove. An angle 44 and a bevel 45 are respectively provided on the outer wall of the wedge-shaped buckle 41. When welding the probe 54 of the microwave module 56 to the connecting wire 55, the connecting wire 55 is first horizontally inserted into the V-shaped receiving groove 46 at the top of the positioning plate 14. During this process, the outer wall of the connecting wire 55 first contacts the top of the wedge-shaped buckle 41. The two retaining springs 43 return to their initial state from a tightened state, causing the slide bar 42 to slide out of the socket and drive the wedge buckle 41 to reset, pressing the outer wall of the connecting wire 55 through the bevel 45 on the wedge buckle 41 to achieve a positioning effect, facilitating the subsequent rapid welding of the connecting wire 55 and the probe 54.

[0037] Reference Figures 1 to 12 As shown, a V-shaped receiving groove 46 is provided on the top of each positioning plate 14. The V-shaped receiving groove 46 is designed to be wide at the top and narrow at the bottom, which can accommodate connecting wires 55 of different diameters and achieve welding with the probe 54, thereby meeting different positioning requirements.

[0038] Reference Figures 1 to 12As shown, a U-shaped plate is fixed on the top of the welding table 10, and a second screw rod 47 is rotatably provided on the outer wall of the U-shaped plate. A micro motor 48 is fixed on the top of the U-shaped plate, and its output end is fixedly connected to the top of the second screw rod 47.

A lap plate 51 is fixed on the top of the mounting rod 50. Two slide bars 52 are fixed at both ends of the mounting rod 50. Two slide grooves 53 are symmetrically provided on the top of the welding table 10. Each slide bar 52 is slidably connected to a slide groove 53. When the connecting line 55 After being aligned with the probe 54 in an up-and-down position, the micromotor 48 is started by the controller, so that its output end rotates. Since the second screw rod 47 is threadedly connected to the lifting block 49, the lifting block 49 is fixedly connected to the mounting rod 50, and the mounting rod 50 is fixedly connected to the lap plate 51. The mounting rod 50 is slidably connected to the two slide grooves 53 through two slide bars 52, thereby driving the lap plate 51 to rise vertically until the probe 54 is driven to rise to maintain a suitable welding distance with the connecting line 55, which facilitates and quickly welds, avoids the connection line 55 and the probe 54 being too far away from each other and causing cold welding or welding dislocation, and is beneficial to improving welding quality.

[0039] The working principle of the present invention is as follows: when welding the probe 54 of the microwave module 56 and the connecting wire 55, the connecting wire 55 is first inserted horizontally into the V-shaped receiving groove 46 at the top of the positioning plate 14. During this process, the outer wall of the connecting wire 55 first contacts the bevel 44 at the top of the wedge-shaped buckle 41. After the wedge-shaped buckle 41 is resisted by the connecting wire 55, the two tightening springs 43 are changed from the initial state to the tight state, and the slide bar 42 is retracted to the inside of the jack, thereby causing the wedge-shaped buckle 41 to retract to the inside of the groove, thereby causing the connecting wire 55 to be inserted into the V-shaped receiving groove 46. Inside, when the connecting wire 55 is in place, the wedge-shaped buckle 41 is no longer resisted by it. At this time, the two retaining springs 43 return to the initial state from the taut state, thereby causing the slide rod 42 to slide out of the socket and drive the wedge-shaped buckle 41 to reset. The outer wall of the connecting wire 55 is pressed by the bevel 45 on the wedge-shaped buckle 41 to have a positioning effect, which facilitates the subsequent rapid welding of the connecting wire 55 and the probe 54. The V-shaped receiving groove 46 has a design structure that is wide at the top and narrow at the bottom, which can accommodate connecting wires 55 of different diameters and achieve welding with the probe 54, thereby meeting different positioning requirements.

[0040] This device is equipped with a controller, and each electrical device on the device is electrically connected to the controller. After several connecting wires 55 are horizontally placed inside several V-shaped receiving grooves 46 on the positioning, first, manually grasp the microwave module 56 and make it horizontally suspended between two clamping plates 15, and then start the servo motor 25 through the controller, so that its output end rotates. Since its output end is fixedly connected to the driving wheel 26, the driven wheel 27 is fixedly connected to the rotating shaft 28, the rotating shaft 28 is rotationally connected to the mounting table, and the driving wheel 26 and the driven wheel 27 are sleeved by the first belt 29, the rotating shaft 28 is driven to rotate slowly. Since each sliding column 30 is slidably connected to a slide rail, each clamping plate 15 is fixedly connected to the top of every two sliding columns 30, the rotating shaft 28 is fixedly connected to the turntable 31, and one end of the turntable 31 and each clamping plate 15 are hinged to both ends of a connecting rod 32, the two clamping plates 15 are driven to slowly approach each other, clamping both ends of the microwave module 56. By designing the rotating assembly, the two clamping plates 15 can be driven to approach or move away from each other, meeting the clamping requirements for microwave modules 56 of different sizes, and further meeting the welding requirements for the probes 54 of microwave modules 56 of different size specifications, improving the practicability of this device.

[0041] When the two clamping plates 15 clamp both ends of the microwave module 56, the two supporting plates 33 on the top of each clamping plate 15 support the bottom end of the microwave module 56, further improving the clamping stability of the microwave module 56, which is beneficial to improving the welding effect with the connecting wire 55. Since the designed height of the supporting plate 33 is lower than the designed height of the V-shaped receiving groove 46, all the probes 54 of the clamped microwave module 56 are exactly located directly below all the connecting wires 55.

[0042] After the connecting wire 55 and the probe 54 are aligned in a vertical and horizontal arrangement, start the micro-motor 48 through the controller, so that its output end rotates. Since the second lead screw 47 is threadedly connected to the lifting block 49, the lifting block 49 is fixedly connected to the mounting rod 50, the mounting rod 50 is fixedly connected to the overlapping plate 51, and the mounting rod 50 is slidably connected to the two chutes 53 through two slide bars 52, the overlapping plate 51 is driven to rise vertically until the probe 54 is driven to rise to a suitable welding distance from the connecting wire 55, facilitating quick welding, avoiding poor welding or welding misalignment caused by too large a distance between the connecting wire 55 and the probe 54, and being beneficial to improving the welding quality.

[0043] When all the probes 54 on the microwave module 56 are pushed upward to be in close contact with all the connecting wires 55, the first slider 36 is driven to slide horizontally by the electric slide 34. Since the first slider 36 is fixedly connected to the slideway 39 through the L-shaped block 37, the cylinder 35 is inserted into the L-shaped block 37, and its output end is fixedly connected to the mounting block 40. The welding head 16 is fixedly connected to the second slider 38 through the mounting block 40, and the second slider 38 is slidably connected to the slideway 39. Thus, the welding head 16 is driven by the first slider 36 to slide horizontally to the directly above the first connecting wire 55. Then, the cylinder 35 is started through the controller, and its output end drives the mounting block 40 and the welding head 16 thereon to descend, welding the first connecting wire 55 and the first probe 54 together. Then, the welding head 16 is driven to rise by the cylinder 35, and the welding head 16 is driven by the first slider 36 on the electric slide 34 to move horizontally to the directly above the second connecting wire 55. According to the above welding steps, the welding work of the remaining connecting wires 55 and probes 54 is realized.

[0044] When the size of the microwave module 56 to be processed increases, the spacing between all the probes 54 on the microwave module 56 will also increase synchronously. Thus, the spacing between the connecting wires 55 welded to all the probes 54 also needs to increase synchronously. At this time, it is necessary to synchronously increase the spacing between several sliding plates 12 and several positioning plates 14 to meet the positioning requirements of several connecting wires 55 with different spacings. Thus, the stepping motor 17 is started through the controller, and its output end drives one of the synchronous wheels 20 to rotate. Since the other synchronous wheel 20 is fixedly connected to the first lead screw 19, the two synchronous wheels 20 are sleeved through the synchronous belt 18, the moving block 21 is fixedly connected to the adjusting plate 11, the moving block 21 is threadedly connected to the first lead screw 19, and the adjusting plate 11 is slidably connected to the mounting plate 13. Thus, the adjusting plate 11 is driven to slide horizontally toward the end close to the L-shaped plate.

[0045] When the adjusting plate 11 slides horizontally toward the end close to the L-shaped plate, since the adjusting plate 11 is slidably connected to the two guide rails 22, there are four guide blocks 23 equidistantly arranged between the two guide rails 22, several sliding plates 12 are slidably connected to the four guide blocks 23, each sliding plate 12 is fixedly connected to a traction rod 24, and avoiding grooves for several traction rods 24 to slide are designed on the outer wall of the adjusting plate 11, and the avoiding grooves are inclined. Further, when the several avoiding grooves move toward the end close to the L-shaped plate, the resistance generated on the several traction rods 24 drives the several sliding plates 12 and the positioning plates 14 to move away from each other, that is, the spacing between every two adjacent positioning plates 14 is increased, meeting the alignment requirements of several connecting wires 55 and several probes 54 on the outer wall of the larger-sized microwave module 56, and facilitating rapid welding.
