Description

Technical Field

[0001] This invention relates to the field of inductor soldering equipment, and more specifically to a jet soldering machine gripping device. Background Technology

[0002] Current inductors require soldering the soldering terminals. This process involves removing the protective film from the terminals, then soldering them, defining the diameter, and reshaping them. Previously, these steps—removing the film, defining the diameter, and reshaping—all required manual operation and a specific mold with through-holes through which the soldering terminals passed and were pulled. This controlled the diameter and reshaping of the terminals. However, this manual operation was dangerous due to the high temperature of the freshly soldered terminals and reduced processing efficiency. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes a jet soldering machine gripping device, which facilitates the automatic removal of the film, soldering, diameter setting, and shaping of the inductor soldering terminals, thereby reducing manual labor and improving production efficiency.

[0004] To achieve the above objectives, the present invention provides a solution: a jet soldering machine gripping device, comprising a soldering platform, a Handa jig, a clamping mechanism, and an inductor gripping mechanism. A solder pot is provided on the soldering platform, and a clamping mechanism is provided above the solder pot. A first lifting component is provided between the clamping mechanism and the soldering platform. The Handa jig clamps the inductor and places it on the clamping mechanism for clamping. An inductor gripping mechanism is provided above the clamping mechanism to move the inductor upward. The Handa jig is divided into two halves, forming a clamping groove for clamping the inductor. A limiting through hole for the soldering terminal pin to pass through is provided at the bottom of the clamping groove. The back sides of multiple inductors are fixed on a connecting piece, and the connecting piece enables the synchronous lifting and lowering of multiple inductors. The inductor gripping mechanism clamps the connecting piece. A second lifting component is provided on the inductor gripping mechanism to enable the lifting and lowering of the connecting piece.

[0005] Preferably, the inductive gripping mechanism includes a gripping arm and a finger gripping cylinder B. The cylinder body of the finger gripping cylinder B is mounted on a second lifting assembly. The lifting and lowering of the finger gripping cylinder B is achieved through the second lifting assembly. The gripper of the finger gripping cylinder B is fixed to the gripping arm, and the connecting piece is clamped by the swinging of the gripping arm.

[0006] Preferably, the clamping mechanism includes a bracket, a fixture positioning component, and a fixture clamping component. The bracket consists of two parallel brackets, each mounted on the same crossbeam. The crossbeam is connected to the first lifting component. Each bracket is equipped with a fixture positioning component for clamping two half-table fixtures. Above the two brackets, multiple fixture clamping components are provided. The fixture clamping components are used to clamp the two half-table fixtures on both sides. The fixture clamping components are also mounted on the crossbeam.

[0007] Preferably, a positioning module is provided between the half-Half ... A finger-gripping cylinder A is installed between the clamping plates; the jig gripping assembly includes gripping cylinders and gripping arms. There are multiple sets of gripping cylinders, and gripping arms are installed on the sliding arms at the bottom of the multiple sets of gripping cylinders. The sides of the hand jig are clamped by two gripping arms. The bottom of the sliding arm rests against the top surface of the hand jig. The distance between the sliding arms is for the lifting and lowering of the connecting plate. A linkage frame is installed above the multiple gripping cylinders, and the cylinder body of each gripping cylinder is installed on the linkage frame. A third lifting assembly is installed between the linkage frame and the crossbeam. The third lifting assembly enables the synchronous lifting and lowering of multiple jig gripping assemblies.

[0008] Preferably, a sealing cover is provided on the welding platform, and a notch is opened on the front of the sealing cover. A sliding door is provided at the notch. An opening cylinder is provided between the door and the sealing cover. The door is raised and lowered by the opening cylinder. The opening cylinder is raised and lowered synchronously with the first lifting assembly. The top of the first lifting assembly is installed on the top of the sealing cover. The piston rod of the first lifting assembly is fixed to the crossbeam by a column. The cylinder body of the third lifting assembly is fixed to the cylinder body of the first lifting assembly.

[0009] Preferably, an inductance switching mechanism is provided on the sealing door to switch the inductance between the welding platform and the inductance gripping mechanism. The inductance switching mechanism includes a gripping component, a swing arm, and a rotating plate. A notch is provided on the sealing door, and the rotating plate is embedded in the notch and rotatably connected to the sealing door. Two swing arms are hinged to the front and flip surfaces of the rotating plate, and a gripping component is installed on the other end of the swing arm. The gripping component grips the hand jig. A telescopic component is provided between the swing arm and the rotating plate, and a linkage is fixed on the piston rod of the telescopic component. The linkage rod is connected to two swing rods on the same side of the rotating plate. The cylinder of the telescopic component is hinged to the rotating plate. The gripping component is a finger cylinder. The gripping arm of the finger cylinder has a clamping groove with opposite openings. The clamping groove clamps the Handa jig.

[0020] like Figure 1-7 As shown, the jet soldering machine gripping device includes a soldering platform 1, a Handa jig, a clamping mechanism 3, and an inductor gripping mechanism 13. A solder pot 15 is installed on the soldering platform 1, and the clamping mechanism 3 is installed above the solder pot 15. A first lifting assembly 16 is installed between the clamping mechanism 3 and the soldering platform 1. The Handa jig clamps the inductor and places it on the clamping mechanism 3 for clamping. The inductor gripping mechanism 13 is installed above the clamping mechanism 3, and the inductor is moved towards the soldering platform 1 by the inductor gripping mechanism 13. The upper movement; the Handa jig is divided into two halves, and the two halves of the Handa jig form a clamping groove 17 for clamping inductors. A limiting through hole 18 for soldering terminal pins to pass through is provided at the bottom of the clamping groove 17. The back of multiple inductors is fixed on the connecting piece 19. Multiple inductors are raised and lowered synchronously through the connecting piece 19. The inductor clamping mechanism clamps the connecting piece 19.

[0021] The inductive gripping mechanism 13 includes a gripping arm 14 and a finger gripping cylinder B. The cylinder body of the finger gripping cylinder B is mounted on the second lifting assembly 20. The lifting and lowering of the finger gripping cylinder B is achieved through the second lifting assembly 20. The air gripper of the finger gripping cylinder B is fixed to the gripping arm 14. The connecting piece 19 is clamped by the swinging of the gripping arm 14.

[0022] The clamping mechanism 3 includes a bracket 4, a fixture positioning component 6, and a fixture clamping component 7. There are two brackets 4, which are parallel to each other. Each bracket 4 is mounted on the same crossbeam 5. The crossbeam 5 is connected to the first lifting component 16. Each bracket 4 is provided with a fixture positioning component 6 for clamping two half-table fixtures. Multiple fixture clamping components are provided above the two brackets 4. The fixture clamping components 7 are used to clamp the two half-table fixtures on both sides. The fixture clamping components 7 are also mounted on the crossbeam 5.

[0023] A positioning module 21 is provided between the halves of the halves of the fixture. The positioning module 21 consists of a positioning pin 22 and a positioning hole 23. The positioning pin 22 and the positioning hole 23 are respectively provided on the mating surfaces of the two halves of the halves of the fixture. The positioning pin 22 extends into the positioning hole 23 for positioning. A tapered through hole is provided at both ends of each half of the halves of the fixture. The fixture positioning component 6 is a clamping piece 28. Long slots for the clamping piece 28 to pass through are opened on both sides of the bracket 4. A placement slot 29 for placing the end of the halves of the fixture is opened on the top of the bracket 4. The clamping piece 28 extends into the placement slot 29 and is fixed with a vertically upward-pointing cylinder. The cylinder is inserted into the through holes at both ends of the halves of the fixture. The two clamping pieces on the same side... A finger-gripping cylinder A is provided between the clamping plates; the jig clamping assembly 7 includes clamping cylinders 8 and clamping arms 9. There are multiple sets of clamping cylinders 8, and clamping arms 9 are installed on the sliding arms 10 at the bottom of the multiple sets of clamping cylinders 8. The sides of the Handa jig are clamped by two clamping arms 9. The bottom of the sliding arms 10 rests on the top surface of the Handa jig. The distance between the sliding arms 10 is for the lifting and lowering of the connecting plate. A linkage frame 11 is provided above the multiple clamping cylinders 8, and the cylinder body of each clamping cylinder 8 is installed on the linkage frame 11. A third lifting assembly 12 is provided between the linkage frame and the crossbeam 5. The multiple jig clamping assemblies 7 are lifted and lowered synchronously by the third lifting assembly 12.

[0024] A sealing cover 24 is placed on the welding platform 1. A notch 25 is opened on the front of the sealing cover 24. A sliding door 26 is provided at the notch 25. An opening cylinder 27 is provided between the door 26 and the sealing cover 24. The door 26 is raised and lowered by the opening cylinder 27. The opening cylinder 27 is raised and lowered synchronously with the first lifting assembly 16. The top of the first lifting assembly 16 is installed on the top of the sealing cover 24. The piston rod of the first lifting assembly 16 is fixed to the crossbeam 5 by a column. The cylinder body of the third lifting assembly 12 is fixed to the cylinder body of the first lifting assembly 16.

[0025] When the solder bath temperature is too high, the aforementioned hand jigs are mainly handled by workers above the solder bath, which poses a significant risk. An inductor switching mechanism 30 is installed on the sealing door 26. This mechanism eliminates the need for manual hand placement above the solder bath, reducing risk. When manual replacement of the hand jig on the inductor clamping mechanism is required, the inductor switching mechanism 30 is not activated; the hand jig can be switched simply by raising and lowering the sealing door. When hand jig switching is needed via the inductor switching mechanism 30, the sealing door is closed, disconnecting the air path of the door-opening cylinder. The sealing door remains closed, and the inductor switching mechanism 30 switches the inductance between the soldering platform and the inductor clamping mechanism. The structure 30 includes a gripping component 31, swing rods 34, and a rotating plate 35. A notch is cut into the sealing door, and the rotating plate 35 is embedded within the notch (the outer wall of the rotating plate 35 fits against the inner wall of the notch). The rotating plate 35 is rotatably connected to the sealing door (rotating shafts are welded to both ends of the rotating plate 35 at the top, and these shafts are mounted on the sealing door via bearings. The top rotating shaft is welded to the output shaft of a stepper motor, thus enabling the rotating plate 35 to rotate 180 degrees). Two swing rods 34 are hinged to both the front and flip surfaces of the rotating plate 35, arranged side-by-side. The gripping component 31 is bolted to the other end of each swing rod 34, and the gripping component 31 grips the hand-held jig. A telescopic assembly 36 is provided on the swing rod 34 and the rotating plate 35. A linkage rod 37 is fixed to the piston rod of the telescopic assembly 36 by welding, and the linkage rod 37 is connected to two swing rods 34 on the same plane of the rotating plate 35 (the two ends of the linkage rod 37 are fixed to the swing rods 34 by bearings). The cylinder of the telescopic assembly 36 is hinged to the rotating plate 35. By lifting the telescopic assembly 36 (the telescopic assembly 36 is a telescopic cylinder), when the swing rod 34 needs to be in a horizontal state, the telescopic assembly 36 retracts, and the swing rod 34 swings downward to a horizontal state. When the swing rod 34 needs to swing vertically upward, the telescopic assembly 36 lifts, and the swing rod 34 swings upward to a vertically upward state. (The last sentence appears to be an incomplete thought or fragment.) 1 refers to the finger cylinder. A clamping groove 32 (the clamping groove 32 is a channel steel) with opposite openings is fixed to the clamping arm of the finger cylinder by bolts. The Handa jig is clamped in the clamping groove 32. A pulley 33 is fixed to the inner wall of the clamping groove 32 by bolts. The side of the Handa jig abuts against the pulley 33, which facilitates the sliding of the Handa jig. Alignment components 38 are installed on the front and back of the rotating plate 35 by bolts. When the swing rod 34 is in contact with the rotating plate 35, alignment components 38 are set on both sides of the Handa jig. The alignment components 38 are limit plates. The side of the limit plate facing the Handa jig is an inward inclined slope. When the swing rod 34 swings up, the limit plate limits the two ends of the Handa jig.During operation, the worker places the Handa jig, which contains the inductor, into the clamping groove 32. A finger cylinder clamps the jig in the groove 32. Then, the swing rod 34 swings upward, causing the Handa jig to slide along the inclined surface of the limiting plate. This limiting plate restricts the two ends of the Handa jig, facilitating its subsequent placement on the inductor gripping mechanism. After the Handa jig is placed, the rotating plate 35 rotates 180° under the action of a stepper motor, rotating the outer Handa jig into the sealing cover. Then, the swing rod 34 swings downward to place the Handa jig onto the inductor gripping mechanism. Simultaneously, the swing rod 34 swings upward. Once the inductor on the gripping mechanism is welded, the swing rod 34 swings downward to remove the Handa jig from the gripping mechanism. At the same time, the rotating plate 35 rotates, moving the welded inductor out of the sealing cover.
