[0075] The double tin pump soldering mechanism of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0076] Reference Figures 1 to 6 As shown, the dual-tin pump soldering mechanism provided according to an embodiment of the present invention includes a base 10 , two sliding seats 20 , two lifting frames 30 , two solder pumps 40 and two first drive assemblies 50 .

[0077] The two sliding seats 20 are spaced apart on the base 10 and can slide along the length direction of the base 10;

[0078] The two lifting frames 30 are disposed above the two sliding seats 20 and are opposite to each other, and can move along the length direction of the base 10 with the sliding seats 20 .

[0079] The two solder pumps 40 are disposed opposite to each other above the two lifting frames 30 and can be raised and lowered along with the lifting frames 30 .

[0080] The two first driving components 50 are respectively disposed at both ends of the sliding base 20 , and the output ends thereof are connected to the sliding base 20 , so as to drive the sliding base 20 to slide along the length direction of the base 10 .

[0081] Based on the above, by equipping two relatively arranged solder pumps 40, it can be equipped with different nozzles or the same nozzle, so that it can perform soldering operations simultaneously or independently, which significantly improves work efficiency. In addition, the design of the sliding seat 20 and the lifting frame 30 enables the solder pump 40 to flexibly adjust its position in the horizontal and vertical directions to adapt to the welding requirements of different sizes and shapes, thereby increasing the flexibility and adaptability of operation. The dual-tin pump soldering mechanism, with its high efficiency, flexibility, precise control, automation potential, stability and durability, and easy maintenance and upgrading, brings significant beneficial effects to soldering operations.

[0082] Preferably, in an embodiment of the present invention, the two lifting frames 30 each include a lower frame body 301 , an upper frame body 302 and a second driving assembly 303 .

[0083] The lower end of the lower frame 301 is connected to the sliding seat 20 , and a first installation space 3011 is formed inside the lower frame 301 .

[0084] The upper frame 302 is disposed above the upper frame 302 , the solder pump 40 is disposed in the middle of the upper frame 302 , and a second installation space 3021 is formed inside the upper frame 302 .

[0085] The second driving assembly 303 is connected between the upper frame 302 and the lower frame 301 to drive the upper frame 302 to move up and down.

[0086] The middle portions of the upper frame 302 and the lower frame 301 are both hollowed out, and the lower end of the solder pump 40 extends into the upper frame 302 and the lower frame 301 .

[0087] Thus, by designing the lifting frame 30 to include a lower frame 301, an upper frame 302, and a second drive assembly 303, and by creating a hollowed-out center portion between the upper frame 302 and the lower frame 301, this design not only optimizes the overall structure but also significantly reduces the weight of the lifting frame 30. The reduced weight makes the lifting frame 30 more flexible during movement, reduces energy consumption, and also improves the device's responsiveness and stability. The provision of the second drive assembly 303 allows for smoother and more precise lifting and lowering of the upper frame 302. This precise lifting control helps ensure the stable position of the solder pump 40 during the soldering process, thereby improving soldering quality and consistency.

[0088] Since the lower end of the solder pump 40 extends into the upper frame 302 and the lower frame 301, this design makes full use of the space inside the lifting frame 30, making the entire soldering mechanism more compact in the vertical direction, which is conducive to installing more equipment in a limited working area or performing other layout optimizations.

[0089] Preferably, in an embodiment of the present utility model, the second driving assembly 303 includes a plurality of first nut sleeves 3031 , a plurality of second nut sleeves 3032 , a plurality of first screw rods 3033 and a first driving motor 3034 .

[0090] The plurality of first nut sleeves 3031 are all passed through the lower frame 301 and arranged in a rectangular array.

[0091] The plurality of second nut sleeves 3032 are all disposed on the upper frame 302 and are arranged one by one opposite to the plurality of first nut sleeves 3031 .

[0092] The upper ends of multiple first screw rods 3033 are oppositely arranged in the second nut sleeve 3032 and extend into the second installation space 3021. The lower ends of multiple first screw rods 3033 are oppositely arranged in the first nut sleeve 3031 and extend into the first installation space 3011.

[0093] The first driving motor 3034 is disposed on a side of the lower frame 301 and is used to drive the plurality of first screw rods 3033 to rotate simultaneously.

[0094] In this way, by adopting a combination of multiple first nut sleeves 3031, second nut sleeves 3032 and first screw rods 3033, a stable lifting mechanism is formed. When the first drive motor 3034 drives the multiple first screw rods 3033 to rotate simultaneously, the upper frame 302 can move up and down smoothly along the screw rods, ensuring the stability and accuracy of the solder pump 40 during the lifting process. Multiple first nut sleeves 3031 and second nut sleeves 3032 are arranged in a rectangular array. This layout helps to disperse the force during the lifting process and avoid structural damage caused by excessive force at a single point. At the same time, it also enhances the overall structural strength of the lifting frame 30 and improves the durability and reliability of the equipment.

[0095] At the same time, because the multiple first screw rods 3033 are driven simultaneously by the first drive motor 3034, the various parts of the upper frame 302 can be raised and lowered synchronously, avoiding tilting or shaking caused by asynchronous movement. This synchronous lifting mechanism helps ensure precise position control of the solder pump 40 during the lifting process, improving the accuracy and consistency of welding.

[0096] Preferably, in an embodiment of the present invention, a first transmission wheel 3035 is provided at the lower end of each first screw rod 3033 , and a plurality of first transmission wheels 3035 are provided in the first installation space 3011 .

[0097] A first driving wheel 3036 is provided at the output end of the first driving motor 3034 . The first driving wheel 3036 and the plurality of first transmission wheels 3035 are connected via a first transmission belt 3038 , so that the first driving motor 3034 drives the plurality of first screw rods 3033 to rotate synchronously.

[0098] In this way, the power of the first drive motor 3034 is transmitted to the multiple first transmission wheels 3035 through the first transmission belt 3038, which in turn drives the multiple first screw rods 3033 to rotate synchronously, ensuring the stability and synchronization of the upper frame 302 during the lifting process. This synchronous lifting mechanism is crucial for maintaining the precise position of the solder pump 40 during the welding process, and helps to improve the welding quality and consistency. Compared with other complex synchronous drive mechanisms, this method of connecting the first driving wheel 3036 and the multiple first transmission wheels 3035 through the first transmission belt 3038 is simpler and more compact. It reduces the number and complexity of transmission components, reduces manufacturing costs and maintenance difficulties. Of course, in order to increase the service life, the belt drive of the first transmission belt can be replaced with a chain drive, that is, teeth are provided on both the first transmission wheel 3035 and the first driving wheel 3036.

[0099] Preferably, in one embodiment of the present invention, it further includes two tensioning wheels 3037, the two tensioning wheels 3037 are arranged in the first installation space 3011 and close to the first driving wheel 3036, the two tensioning wheels 3037 are spaced between the two adjacent first transmission wheels 3035, and the two adjacent first transmission wheels 3035 are close to the first driving wheel 3036, and the surfaces of the two tensioning wheels 3037 are both in contact with the outer surface of the first transmission belt to tighten the transmission.

[0100] Thus, the function of tensioning pulley 3037 is to maintain appropriate tension in the transmission belt, preventing it from excessively loosening or vibrating during operation. By ensuring close contact between the transmission belt and each transmission pulley, tensioning pulley 3037 significantly improves the stability of the transmission system, thereby ensuring the precision and reliability of the synchronous rotation of the first screw rod 3033. Appropriate tension can reduce wear and fatigue of the transmission belt during operation, preventing slippage and excessive wear caused by looseness. Therefore, the presence of tensioning pulley 3037 helps extend the service life of the transmission belt, reducing replacement frequency and maintenance costs.

[0101] Preferably, in an embodiment of the present invention, a slide rail 101 is provided on the upper surface of the base 10 , and the slide rail 101 extends along the length direction of the base 10 , and both of the sliding seats 20 are slidably provided on the slide rail 101 .

[0102] In this way, the sliding seat 20 can slide freely on the slide rail 101, which means that the position of the sliding seat 20 can be easily adjusted according to specific work needs or scenarios. This flexibility and adjustability enable the present invention to adapt to a wider range of application scenarios, improving the versatility and practicality of the device. The matching design between the slide rail 101 and the sliding seat 20 ensures smoothness and accuracy during the sliding process. The sliding of the sliding seat 20 on the slide rail 101 is controllable, and the slide rail 101 provides stable support for the sliding seat 20, thereby ensuring the stability of the entire transmission system during operation.

[0103] Preferably, in an embodiment of the present invention, the two first drive assemblies 50 include a second screw rod 501 , a second drive motor 502 and a third nut sleeve 503 .

[0104] The base 10 is provided with two through slots 102 , which are spaced apart along the length direction of the base 10 and pass through the upper surface of the base 10 . The second screw rod 501 is rotatably mounted in the through slots 102 , and its end extends to the end surface of the base 10 .

[0105] The second driving motor 502 is connected to an end of the second screw rod 501 to drive the second screw rod 501 to rotate.

[0106] The third nut sleeve 503 is connected to the bottom surface of the sliding seat, and the second screw rod 501 is inserted into the third nut sleeve 503 .

[0107] In this way, the second drive motor 502 drives the second screw rod 501 for precise rotation, and the screw rod and nut sleeve cooperate to achieve precise linear movement of the sliding seat on the base 10. This transmission method has high positioning accuracy and repeatability, suitable for scenarios requiring precise position control. By providing a through slot 102 in the base 10 to accommodate the second screw rod 501, the entire drive mechanism is compact and does not occupy excessive space, which is beneficial for the overall layout and integration of the device.

[0108] Preferably, in one embodiment of the present invention, a second transmission wheel 504 is provided at the end of the second screw rod 501, the output end of the second drive motor 502 is connected to a second driving wheel 505, and the second driving wheel 505 and the second transmission wheel 504 are connected by a second transmission belt 507.

[0109] Thus, by introducing the combination of the second transmission wheel 504, the second driving wheel 505 and the second transmission belt 507, the design in this embodiment not only improves the operational stability and reliability of the equipment, but also enhances the flexibility and maintainability of the system, further improving the overall performance.

[0110] Preferably, in an embodiment of the present invention, a speed reducer 506 is provided between the output end of each second drive motor 502 and the second driving wheel 505 to reduce the output speed of the output end of the second drive motor 502 .

[0111] In this way, the speed reducer 506 reduces the rotation speed, making the rotation of the second screw rod 501 smoother and more precise. This helps to reduce the vibration and impact caused by high-speed rotation, thereby improving the overall accuracy and stability of the transmission system. While reducing the rotation speed, the speed reducer 506 generally increases the output torque. This means that under the same motor power, the speed reducer 506 can drive heavier loads or achieve greater thrust, thereby enhancing the load capacity and working efficiency of the equipment.

[0112] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0113] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
