Description

Technical Field

[0001] The utility model relates to the technical field of capacitor processing, in particular to an automatic tinning wire welding machine for capacitors. Background Art

[0002] During the processing of capacitors, the leads need to be welded to the two ends of the core. In order to improve the welding quality between the leads and the core, prevent oxidation, increase the welding speed and protect the leads, one end of the leads needs to be dipped in tin before welding to the core. However, when the existing wire welding machines are dipped in tin, the length of the leads extending into the tin box is easily too long or too short, resulting in more or less tin on one end of the leads. Too much tinning will cause a waste of tin liquid, and too little tinning will affect the welding quality, thereby reducing the product quality. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The core of a capacitor is usually composed of a dielectric and electrodes, while the lead is the wire used to connect the capacitor to a circuit board or other components. During the welding process, solder or other welding materials are usually used to weld the lead to the capacitor core. This ensures a good electrical connection between the lead and the capacitor core, while also ensuring the performance and stability of the capacitor.

[0024] Embodiment 1:

[0025] Based on the technical defects of uneven lead tinning in the existing technology, please refer to Figure 1-Figure 5 The utility model provides an automatic tinning wire welding machine for capacitors, which makes the distance from one end of the lead wire to the tin box 6 constant, and can take an equal amount of tin liquid, which avoids the waste of tin liquid and ensures the welding quality of the lead wire and the core body. A mounting platform 2 is fixed on the frame 1, and a side plate 3 is fixed on the mounting platform 2. A tinning mechanism 4 for making the tinning amount of one end of the lead wire uniform is provided on the side plate 3. A feeding tray 7 is also rotatably connected to the front of the mounting platform 2, and a welding mechanism 8 for synchronously welding the two ends of the core body is provided above the feeding tray 7. The welding mechanism 8 is fixed on the mounting platform 2; after the lead wire is placed on the tinning mechanism 4, the tinning mechanism 4 is moved and the lead wire is moved to the position of the tin box 6, and then the lead wire is moved back to the original position after the tinning is completed. At this time, the feeding tray 7 drives the core body to move to the middle position of the lead wire, and the lead wire and the core body are welded by the welding mechanism 8.

[0026] To facilitate the control lead to move to the position of the tin box 6, please refer to Figure 2The tinning mechanism 4 includes a motor 41 installed on the back of the side plate 3, a rocker arm 42 is fixedly provided on the output shaft of the motor 41, a movable hole is opened at the top of the rocker arm 42, a fixed block 43 is slidably arranged in the movable hole, the fixed block 43 is fixedly connected to the back of a slider 44, the slider 44 is slidably arranged in a sliding hole 1 opened on the side plate 3, a movable plate 45 is movably connected to the slider 44, a clamping assembly 47 for clamping the positive and negative leads is provided at the bottom of the movable plate 45, the motor 41 is used to drive the rocker arm 42 to rotate, the rocker arm 42 drives the slider 44 to move horizontally through the fixed block 43, and the slider 44 can drive the lead on the clamping assembly 47 to move through the movable plate 45.

[0027] In order to facilitate the upward reset of the lead after tinning, a spring 46 elastically connected to the slider 44 is installed on the inner side of the movable plate 45. When the pressure wheel 48 is squeezed downward by the pressure guide block 5, the movable plate 45 moves downward. At this time, the spring 46 is in a compressed state. When the pressure wheel 48 is separated from the pressure guide block 5, the movable plate 45 can be reset upward under the elastic force of the spring 46.

[0028] To facilitate the fixing of the leads, please refer to Figure 3 The clamping assembly 47 includes a cylinder 1 471 installed on the inner side of the movable plate 45, a connecting block 472 is fixedly provided on the telescopic shaft of the cylinder 1 471, the connecting block 472 is hinged to the back of two sliders 474 through a connecting rod 473, the two sliders 474 are respectively slidably arranged in two sliding holes 2 opened at the bottom of the movable plate 45, and the front of the two sliders 474 is fixedly provided with an "L"-shaped clamping claw 475, and the opposite side walls of the two clamping claws 475 are fixedly provided with a rubber block 476. The cylinder 1 471 is operated and drives the connecting block 472 to move, the connecting block 472 drives the slider 474 to move through the connecting rod 473, and the slider 474 drives the clamping claw 475 to move, so that the clamping claw 475 can clamp the two leads, and under the action of the rubber block 476, the clamping claw 475 can prevent the lead from being clamped.

[0029] In order to facilitate one end of the lead to be inserted into the tin box 6 for tinning, a pressure wheel 48 is fixedly provided on the top of the movable plate 45, and a pressure guide block 5 used in conjunction with the pressure wheel 48 is fixedly provided on the side wall of the side plate 3. When the pressure wheel 48 contacts the pressure guide block 5, since one end of the pressure guide block 5 is an inclined surface, the pressure wheel 48 will be squeezed and move downward, and the movable plate 45 will drive the lead to move downward, so that the lead is inserted into the tin box 6 for tinning, and the distance the lead is extended into the inside of the tin box 6 is the height to which the pressure guide block 5 squeezes the pressure wheel 48. Due to the inconvenient size of the pressure guide block 5, the height to which the lead is lowered is constant, so that the same amount of tin liquid can be dipped.

[0030] In order to facilitate tinning, a tin box 6 is provided on the side wall of the side plate 3. The tin box 6 is located directly below the pressure guide block 5. Tin liquid can be filled in the tin box 6 to facilitate the lead wire to be dipped.

The two groups of cylinders 82 are operated synchronously, so that the welding heads 84 can weld the leads at both ends of the core body at the same time.

[0033] Through the above embodiment, it can be known that: the lead is placed between the two clamping jaws 475, the cylinder 1 471 is operated to drive the connecting block 472 to move, the connecting block 472 drives the slider 2 474 to move through the connecting rod 473, and the slider 2 474 drives the clamping jaw 475 to move, so that the clamping jaw 475 can clamp the two lead wires. After the lead wires are fixed, the motor 41 drives the swing rod 42 to rotate, the swing rod 42 drives the slider 1 44 to move horizontally through the fixed block 43, and the slider 1 44 drives the lead wire on the clamping assembly 47 to move through the movable plate 45. When the pressure wheel 48 After contacting the pressure-conducting block 5, since one end of the pressure-conducting block 5 is an inclined surface, the pressure wheel 48 will be squeezed and move downward, and the movable plate 45 drives the lead to move downward, so that the lead is extended into the tin box 6 for tinning. After the tinning is completed, when the slider 44 drives the movable plate 45 to reset, the movable plate 45 moves up and resets under the elastic force of the spring 46. When the lead is reset after tinning, the feeding tray 7 drives the core body to move to the middle position of the lead, and the two groups of cylinders 82 are used to operate synchronously, so that the welding head 84 can weld the leads at both ends of the core body at the same time.
