For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0031] Reference Figures 1 to 8 In an embodiment of the present invention, a soldering machine with a fine-tuning structure comprises: a control console 1, an electric soldering iron 2 is electrically arranged at one end of the control console 1, a connecting block 3 is fixedly arranged on the electric soldering iron 2, a tin feeding tube 4 for guiding the tin wire is fixedly connected to one end of the connecting block 3, the tin feeding tube 4 is a J-shaped pen-shaped hollow tube, a clamping device 5 for clamping one end of the tin wire is slidably arranged on the tin feeding tube 4, so that the tin wire moves in the tin feeding tube 4 following the clamping device 5, a limiting device 7 for limiting the position of the clamping device 5 is arranged on the tin feeding tube 4, two groups of limiting devices 7 are arranged, symmetrically distributed on both sides of the tin feeding tube 4, a locking device 8 for releasing the restriction of the limiting device 7 on the clamping device 5 is arranged in the tin feeding tube 4, an elastic rope 6 for driving the clamping device 5 to reset is arranged on the clamping device 5, one end of the elastic rope 6 passes through the locking device 8 and is connected to the tin feeding tube 4 The top of the tube 4 is fixedly connected, and five groups of elastic ropes 6 are arranged, which are evenly distributed between the clamping device 5 and the top of the tin feeding tube 4. A tin wire rack 13 is fixedly arranged on the console 1. A wire winding rack 12 for winding the connecting wires between the console 1 and the electric soldering iron 2 is fixedly arranged on the console 1. A motor 9 is fixedly connected to one side of the top of the connecting block 3. Two groups of motors 9 are arranged, which are symmetrically distributed at the top of the connecting block 3. The output end of the motor 9 passes through the connecting block 3 and is fixedly connected with a screw rod 10. The screw rod 10 is rotatably connected with a fixed plate at the side end of the tin feeding tube 4. Two groups of fixed plates are arranged, which are symmetrically distributed on both sides of the tin feeding tube 4. A push block 14 is meshed and connected to the screw rod 10. The push block 14 is arranged between the connecting block 3 and the fixed plate at the side end of the tin feeding tube 4. The outer side of the push block 14 is rotatably connected with an outer column 11, and the outer column 11 is a hexagonal column.

[0032] For this explanation, in the technical solution, the control console 1 and the electric soldering iron 2 are prior art. The control console 1 sets the required welding temperature and solder supply speed through the control panel thereon. When welding starts, the heating unit in the control console 1 allows electricity to pass through the heating element, the resistor generates heat, and the heat is conducted to the electric soldering iron 2, so that it is heated to the set temperature. At the same time, the motor 9 is started to move the tin wire toward the electric soldering iron 2, so that the tin wire contacts the electric soldering iron 2 and melts, forming a firm metal connection at the welding point.

[0033] The limiting device 7 includes a limiting rack 71 that is slidably plugged with the side end of the tin delivery tube 4. The limiting rack 71 is composed of a group of straight plates and multiple groups of convex teeth. The multiple groups of convex teeth are evenly distributed on one side of the straight plate and are slidably plugged with the tin delivery tube 4. The top side of the convex teeth on the limiting rack 71 is an inclined surface. One end of the limiting rack 71 is fixedly connected to a spring 72. One end of the spring 72 is fixedly connected to the side end of the tin delivery tube 4. Two groups of springs 72 are provided and are symmetrically distributed on one side of the straight plate.

[0034] By sliding the clamping device 5 downward, the clamping device 5 drives the tin wire to move in the tin feeding tube 4. During the movement, the clamping device 5 abuts against the inclined surface of the limit rack 71 and pushes the limit rack 71 to move outward. After passing through the convex teeth on the limit rack 71, the spring 1 72 drives the limit rack 71 to reset, so that the limit rack 71 is reinserted into the tin feeding tube 4. At this time, the clamping device 5 is released, and under the action of the elastic rope 6, it moves upward until the clamping device 5 abuts against the teeth on the limit rack 71, so that the clamping device 5 is limited to the current position.

[0035] Reference Figures 5 and 6The clamping device 5 includes a moving ring 51 which is slidably connected to the inside of the tin feeding tube 4, and the outer side of the moving ring 51 abuts against the inner wall of the tin feeding tube 4. A clamping piece 52 is slidably arranged in the moving ring 51. Two groups of clamping pieces 52 are arranged, which are symmetrically distributed inside the moving ring 51. A spring 2 53 is fixedly arranged at one end of the clamping piece 52. One end of the spring 2 53 is fixedly connected to the inner wall of the moving ring 51. Four groups of spring 2 53 are arranged, which are symmetrically distributed on the inner wall of the moving ring 51. Each group of clamping pieces 52 is fixedly connected to two groups of spring 2 53. One end of the moving ring 51 is fixedly connected to a moving handle 54. The moving handle 54 consists of a group of straight rods and a group of circular rings. One end of the straight rod of the moving handle 54 is fixedly connected to the moving ring 51, and the other end passes through the tin feeding tube 4 and is fixedly connected to the circular ring on the outer side of the tin feeding tube 4. Two groups of moving handles 54 are arranged, which are symmetrically distributed on both sides of the moving ring 51. Avoidance holes 55 are opened through each group of moving handles 54 to avoid The hole 55 is hexagonal, and the avoidance hole 55 is adapted to the outer column 11. When the tin wire needs to be quantitatively discharged, the outer column 11 is rotated to make the outer column 11 misaligned with the avoidance hole 55, and then the motor 9 is started to drive the screw rod 10 to rotate, so that the push block 14 moves downward on the screw rod 10. During the downward movement of the push block 14, the outer column 11 connected to the outer side of the push block 14 is misaligned with the avoidance hole 55 and cannot pass through the avoidance hole 55, thereby pushing the moving handle 54 to move downward , driving the clamping device 5, so that the tin wire clamped by the clamping device 5 moves downward and is pushed out from the discharge port of the tin feeding tube 4. When soldering non-standard parts, rotate the outer column 11 on the outer side of the push block 14 to align the outer column 11 with the avoidance hole 55, and then manually pull down the clamping device 5 by moving the handle 54, so that the moving handle 54 drives the clamping device 5 to move up and down smoothly. During the movement, the tin wire clamped by the clamping device 5 moves downward and is pushed out from the discharge port of the tin feeding tube 4.

[0036] The above solution allows the user to switch between automatic and manual modes through manual operation by the cooperation of the outer column 11 and the avoidance hole 55, thereby simplifying the entire operation process, reducing the complexity of the operation, and improving the convenience of use.

[0037] Reference Figure 7The clamping member 52 includes a clamping block 521 fixedly connected to one end of the spring 53, a clamping hole 522 is opened at one end of the clamping block 521, and the clamping hole 522 is adapted to the tin wire. A connecting plate 523 is slidably inserted at the side end of the clamping block 521. The connecting plate 523 is provided with two groups, which are symmetrically distributed on both sides of the clamping block 521. The connecting plate 523 is slidably connected to the inner wall of the movable ring 51. A connecting rod 524 is slidably inserted at the top of the clamping block 521, and the connecting rod 524 penetrates the clamping block 521. The top of the connecting rod 524 is fixedly connected to The upper push plate 525 and the lower end of the connecting rod 524 are fixedly connected to the lower push plate 526. The lower end of the upper push plate 525 is fixedly connected to the separation rod 527. The separation rod 527 is semicircular. The lower end of the separation rod 527 is fixedly connected to the lower push plate 526. The lower end of the clamping block 521 is provided with a separation plug plate 528. The separation plug plate 528 is fixedly connected to the separation rod 527. The top of the separation plug plate 528 is an inclined surface. When the clamping device 5 moves downward in the tin feeding tube 4, until the lower push plate 526 abuts against the locking device 8, the locking device 8 is pushed to move. When it reaches the limit position, the lower push plate 526 is subjected to the reaction force and moves upward, and pushes the connecting rod 524, so that the upper push plate 525 moves upward synchronously. During the movement, the inclined surface of the upper end of the separation plug plate 528 is inserted between the two groups of clamping blocks 521, so that the two groups of clamping members 52 move in the opposite direction until the separation plug plate 528 is completely inserted between the two groups of clamping blocks 521. At this time, due to the thrust of the spring 2 53, the separation plug plate 528 is clamped between the two groups of clamping blocks 521, and the clamping member 52 releases the clamping of the tin wire. Under the action of the elastic rope 6, the clamping device 5 moves upward until the upper push plate 525 abuts against the locking device 8 and pushes the locking device 8 to move to the extreme position. The upper push plate 525 is subjected to the reaction force and moves downward, and pushes the connecting rod 524, so that the lower push plate 526 and the separation plug plate 528 move downward synchronously, so that the separation plug plate 528 is pushed out from between the two groups of clamping blocks 521. As the separation plug plate 528 is pushed out, the two groups of clamping blocks 521 move toward each other under the action of spring 2 53, and re-clamp the tin wire.

[0038] The above scheme is adopted: the clamping member 52 can respond quickly during the clamping and releasing process. When the tin wire needs to be clamped, the force of the spring enables the clamping block 521 to firmly clamp the tin wire. When the tin wire is released, the inclined separation plug plate 528 can effectively push the clamping member 52 to open outward, which is convenient and quick.

[0039] Reference Figure 8The locking device 8 is supported by a locking plate 74, and the locking plate 84 is supported by a locking cam 76. The locking plate 84 is provided with four groups, which are evenly distributed between the lower baffle plate 83 and the upper baffle plate 81. When the lower baffle plate 83 abuts against the limit block 73, one end of the limit block 73 abuts against the limit rack 71. The top of the limit block 73 abuts against the locking device 8 to support the locking device 8. The locking device 8 includes a lower baffle plate 83 abutting against the upper end of the limit block 73. The top of the lower baffle plate 83 is fixedly connected to a connecting rod 82. One end of the connecting rod 82 passes through the moving ring 51 and is fixedly connected to the upper baffle plate 81. The moving ring 51 is slidably connected to the connecting rod 82. The connecting rod 82 is provided with four groups, which are evenly distributed between the lower baffle plate 83 and the upper baffle plate 81. The upper baffle plate 81 is U-shaped. When the lower baffle plate 83 abuts against the limit block 73, the bottom end of the upper baffle plate 81 abuts against the top of a group of convex teeth at the upper end of the limit rack 71. When the lower push plate 526 moves downward and pushes the lower baffle plate 83 to move downward, the lower baffle plate 83 pushes the limit block 73 to move outward, and when the lower baffle plate 83 moves downward, the upper baffle plate 81 is driven downward by the connecting rod 82, so that the upper baffle plate 81 pushes the uppermost group of convex teeth of the limit rack 71 to move outward, so that the convex teeth on the limit rack 71 push out the tin feeding tube 4 and maintain the current state. At this time, the clamping device 5 is no longer restricted by the limit rack 71, and moves upward under the action of the elastic rope 6 and returns to the top end of the tin feeding tube 4. When the tin feeding tube 4 returns to the top end, the upper push plate 525 moves upward, pushing the upper baffle plate 81 to move upward, and at the same time drives the lower baffle plate 83 to move upward. At this time, the limit rack 71 is reinserted into the tin feeding tube 4 under the action of the spring 1 72, and at the same time, the limit rack 71 pushes the limit block 73 to insert into the tin feeding tube 4, so that the limit block 73 continues to support the locking device 8.

[0040] The above scheme is adopted: the movement of the clamping device 5 is limited by the limit rack 71 which is slidably plugged into the side end of the tin feeding tube 4, so that the convex teeth on the limit rack 71 can accurately control the supply amount of tin wire according to the amplitude of each movement, thereby achieving precise fine-tuning to meet different welding requirements.

[0041] The working principle of the present invention is as follows: when in use, the tin wire roll is first placed on the tin wire rack 13, and then the clamping device 5 is manually slid down to the bottom end of the tin feeding tube 4 until the lower push plate 526 abuts against the lower baffle 83 and pushes the lower baffle 83 to move to the limit position. At this time, the lower push plate 526 is subjected to the reaction force, moves upward, and pushes the connecting rod 524, so that the upper push plate 525 moves upward synchronously. During the movement, the inclined surface at the upper end of the separation plug plate 528 is inserted between the two groups of clamping blocks 521, so that the two groups of clamping members 52 move in the opposite direction until the separation plug plate 528 is completely inserted between the two groups of clamping blocks 521. At this time, due to the thrust of the spring 2 53, the separation plug plate 528 is clamped between the two groups of clamping blocks 521, so that The two groups of clamping blocks 521 are in an open state, and then this state is manually saved, and one end of the tin wire on the tin wire coil is passed through the connecting block 3, the tin feeding tube 4 and the two groups of clamping blocks 521 in the open state in the tin feeding tube 4 in turn, and passes through the discharge port of the tin feeding tube 4, and then the clamping device 5 is loosened, and the clamping device 5 is moved upward under the action of the elastic rope 6 until the upper push plate 525 abuts against the upper baffle 81. When the upper baffle 81 is pushed to the extreme position, the upper push plate 525 is subjected to a reaction force, moves downward, and pushes the connecting rod 524, so that the lower push plate 526 and the separation plug plate 528 move downward synchronously, so that the separation plug plate 528 is pushed out from between the two groups of clamping blocks 521. The two groups of clamping blocks 521 move toward each other under the force of spring 2 53 to clamp the tin wire. When the tin wire needs to be discharged quantitatively, the outer column 11 is rotated to make the outer column 11 misaligned with the avoidance hole 55, and then the motor 9 is started to drive the screw rod 10 to rotate, so that the push block 14 moves downward on the screw rod 10. During the downward movement of the push block 14, the outer column 11 rotatably connected to the outer side of the push block 14 is misaligned with the avoidance hole 55 and cannot pass through the avoidance hole 55, thereby pushing the moving handle 54 to move downward, driving the clamping device 5, so that the tin wire clamped by the clamping device 5 moves downward and is pushed out from the discharge port of the tin feeding tube 4. When soldering non-standard parts, the outer column 11 on the outer side of the push block 14 is rotated to make the outer column 11 and the avoidance hole 55 is aligned, and then the clamping device 5 is manually pulled down by the moving handle 54, so that the moving handle 54 drives the clamping device 5 to move up and down smoothly. During the movement, the clamping device 5 abuts against the inclined surface of the limit rack 71 and pushes the limit rack 71 to move outward. After passing through the convex teeth on the limit rack 71, the spring 1 72 drives the limit rack 71 to reset, so that the limit rack 71 is reinserted into the tin feeding tube 4. At this time, the clamping device 5 is released and moves upward under the action of the elastic rope 6 until the clamping device 5 abuts against the teeth on the limit rack 71, so that the clamping device 5 is limited to the current position. The manual discharge amount can be judged by the spacing between the two sets of convex teeth on the limit rack 71, thereby fine-tuning the manual discharge amount;The position of the convex teeth on the limit rack 71 can accurately control the movement of the clamping device 5, so that the quantitative supply of the tin wire can be achieved during manual operation, so that the user can make fine adjustments according to the actual welding needs to ensure that the supply of the tin wire during welding is moderate, effectively improving the welding quality and consistency. Through the cooperation of the outer column 11 and the avoidance hole 55, the user can easily switch between manual and automatic modes. The user can choose a more suitable operation mode according to the requirements of the welding task, reducing the complexity of the operation, improving the overall convenience of use, and adapting to different welding scenes. Through the cooperation of components such as the spring 2 53 and the separation plug plate 528, a rapid response in the clamping and releasing process is achieved. When the tin wire needs to be clamped, the clamping block 521 firmly clamps the tin wire, and when releasing, the inclined separation plug plate 528 can effectively open the clamping member 52, achieving fast and convenient operation, improving work efficiency, and helping users to perform welding operations more smoothly. ;

[0042] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
