Through the cooperation of the electric slider 32 and the second electric push rod 34, the solder head 4 can be accurately moved to the position where the electronic component body 5 needs to be soldered.

[0034] Further, the fixing mechanism 2 further comprises a support frame 21 arranged in the cabinet 1, one end of the support frame 21 is fixedly connected with a mounting box 22, one end of the mounting box 22 is fixedly installed with a motor 23, a first screw rod 213 is rotatably installed in the mounting box 22, first screw sleeves 214 are threadedly connected at both ends of the first screw rod 213, the first screw sleeves 214 are slidably connected with the inner wall of the mounting box 22, one end of the first screw sleeve 214 is fixedly connected with the output end of the motor 23, and the upper clamping plate 26 is fixedly connected to the lower surface of the first screw sleeve 214.

[0035] In the present application, the support frame 21 plays a supporting and fixing role for the entire fixing mechanism 2, the first screw sleeves 214 at both ends are driven by the motor 23 to synchronously approach or move away along the mounting box 22, thereby driving the upper clamping plate 26 to synchronously move, so as to realize clamping or loosening of the electronic component body 5. This setting can quickly and accurately fix electronic components of different specifications, and has a wide range of applications.

[0036] Further, the lower clamping plate 27 is hingedly connected to the lower end of the upper clamping plate 26, the upper end of the lower clamping plate 27 is coaxially fixedly connected with a gear 28, one side of the gear 28 is meshingly connected with a rack 29, the rack 29 is slidably connected to a limiting plate 210, and the limiting plate 210 is fixedly connected to one side of the upper clamping plate 26.

[0037] The present application is designed for electronic components with non-planar ends, the upper clamping plate 26 clamps the upper part of the electronic component body 5, and the lower clamping plate 27 clamps the lower part of the electronic component body 5 by rotating, compared with the traditional single clamping plate clamping, the upper clamping plate 26 and the lower clamping plate 27 are clamped at the same time, which can significantly improve the stability of the electronic component body 5 with high side surface during the welding process, thereby improving the welding quality.

[0038] Further, the mounting box 22 is fixedly installed with a first electric push rod 24 on one side, the output end of the first electric push rod 24 is fixedly connected with a lifting plate 25, the lifting plate 25 is movably inserted into a through hole 261, the inner part of both ends of the lifting plate 25 is slidably connected with a limiting sliding block 212, the lower surface of the limiting sliding block 212 is fixedly connected with a lifting rod 211, and the lifting rod 211 slidably penetrates through the upper end of the limiting plate 210 and is fixedly connected with the rack 29 at the bottom.

[0039] Specifically, the upper clamping plate 26 moves synchronously with the first screw sleeve 214 until the upper part of the both sides of the component body 5, and then the first electric push rod 24 is started to drive the lifting plate 25 to move downward, the lifting rod 211 drives the rack 29 to move downward synchronously, and the gear 28 rotates correspondingly, so that the lower clamping plate 27 abuts against the lower part of the both sides of the component body 5, thereby realizing stable clamping of the component body 5. In this process, the lifting plate 25 is in sliding fit with the inner wall of the through hole 261, and the lifting plate 25 plays a limiting role when the upper clamping plate 26 moves left and right, so as to avoid the displacement of the middle and lower parts of the upper clamping plate 26.

[0040] Embodiment 2

[0041] Referring to Figures 1-7 The lifting rod 211 comprises an upper rod body 2111, a spring and a lower rod body 2112. The upper end of the upper rod body 2111 is fixedly connected to the lower surface of the limiting sliding block 212. The lower end of the lower rod body 2112 is fixedly connected to the rack 29. An upper thread groove 2113 is formed on the outer surface of the upper rod body 2111. A lower thread groove 2114 is formed on the outer surface of the lower rod body 2112. The rotation directions of the upper thread groove 2113 and the lower thread groove 2114 are opposite. The spring comprises a fixedly connected upper part 2115 and a lower part 2116. The rotation directions of the upper part 2115 and the lower part 2116 are opposite. The upper part 2115 is connected to the upper thread groove 2113. The lower end of the lower part 2116 is connected to the lower thread groove 2114.

[0042] A second screw sleeve 6 is fixedly connected between the upper part 2115 and the lower part 2116 of the spring. A plug rod 7 is inserted into the second screw sleeve 6. One end of the plug rod 7 is provided with an external thread 8. A plurality of vertically arranged insertion holes 9 are formed on the rack 29. The plug rod 7 can be inserted into one of the insertion holes 9, and the external thread 8 can be threadedly connected with the second screw sleeve 6. A screw groove is formed in the lower end of the lower clamping plate 27. A screw column is rotatably connected in the screw groove. The screw column is an elastic rubber screw column. Through this arrangement, the screw column can be screwed into or out of the screw groove, so that the length of the lower clamping plate 27 can be increased according to the actual situation. Since the screw column is an elastic rubber screw column, it can be attached and pressed against the side of the component body 5.

[0043] The working principle of this embodiment is as follows:

[0044] Elastic clamping and limiting working principle: When fixing electronic components with the automatic soldering machine, the upper clamping plate 26 first clamps the upper part of the two sides of the component body 5 under the drive of the motor 23, and then the first electric push rod 24 drives the lifting plate 25 to move downward. The lifting rod 211 is composed of an upper rod body 2111, a spring, and a lower rod body 2112. During the downward movement of the lifting plate 25, the lower clamping plate 27 first contacts the side of the component body 5. At this time, the lifting plate 25 can still continue to descend. Due to the presence of the spring, the spring is compressed, and the lower clamping plate 27 continues to rotate until the lifting plate 25 presses onto the upper surface of the component body 5, thereby achieving common limiting of the upper surface and the side of the component. Moreover, due to the different elastic compression degrees of the springs in the two lifting rods 211, the lower clamping plates 27 on both sides can rotate at different inclinations to adapt to the sides of components of different shapes.

[0045] Spring adjustment working principle: The spring is composed of an upper part 2115 and a lower part 2116 with opposite rotation directions, which are respectively connected to the upper threaded groove 2113 of the upper rod body 2111 and the lower threaded groove 2114 of the lower rod body 2112. By rotating the spring, the part of the spring extending into the upper threaded groove 2113 and the lower threaded groove 2114 can be increased or decreased, thereby changing the initial length of the entire lifting rod 211. When the part of the spring extending into the threaded groove increases, the initial length of the lifting rod 211 becomes shorter, which can adjust the initial height of the rack 29 to adapt to the clamping needs of objects with different inclinations. At the same time, by rotating the spring, the compression degree of the spring can also be adjusted to adjust the elastic pre-tightening force on the lower clamping plate 27.

[0046] Plug rod and plug hole cooperation working principle: The second screw sleeve 6 fixedly connected between the upper part 2115 and the lower part 2116 of the spring is inserted with a plug rod 7, one end of the plug rod 7 is provided with an external thread 8, and the rack 29 is provided with a plurality of vertically arranged plug holes 9. When the spring needs to be adjusted, the plug rod 7 can be pulled out of the plug hole 9, and the spring can be rotated by turning the plug rod 7, which is convenient to operate. When the plug rod 7 is inserted into one of the plug holes 9 and is screwed with the second screw sleeve 6 through the external thread 8, the spring is limited to prevent it from changing its position due to vibration and other reasons during long-term use, ensuring the accuracy of clamping. Moreover, when the plug rod 7 and the plug hole 9 are connected, only the upper part 2115 of the spring can be elastically stretched, and the lower part 2116 of the spring cannot be elastically stretched, which can further adjust the elastic pre-tightening force on the lower clamping plate 27 to adapt to electronic components of different specifications and materials. Further, the upper part 2115 of the spring is provided with an elastic force sensor, which is signal connected with the first electric push rod 24. When the elastic force of the upper part 2115 of the spring reaches a threshold value, the first electric push rod 24 can be controlled to be turned off. Through this setting, the lower clamping plate 27 can be prevented from damaging the component body 5.

[0047] The working principle of the lower clamping plate length adjustment is that a screw groove is formed at the lower end of the lower clamping plate 27, and the elastic rubber stud connected in rotation can be screwed into or out of the screw groove according to actual needs. When facing electronic components of larger size, the stud can be screwed out to increase the length of the lower clamping plate 27, so that it can better fit and compress the side of the component body 5; when facing smaller size components, the stud can be screwed in to avoid the influence of the too long stud on the operation.

[0048] Through the above settings, the following beneficial effects are achieved:

[0049] Improve clamping stability and adaptability: through the cooperation of the spring and the lifting rod 211, the upper surface and the side of the electronic component are jointly limited, which significantly improves the stability of the component during welding compared to the traditional single clamping method, reducing the problem of poor welding caused by unstable clamping. At the same time, the two lifting rods 211 can be elastically compressed to different degrees, so that the lower clamping plate 27 can rotate to different inclinations, which can adapt to electronic components of various shapes (such as positive ladder type, inverted ladder type, arc shape, positive trapezoidal shape, inverted trapezoidal shape, etc.), greatly expanding the application range of the automatic soldering machine.

[0050] Enhance the convenience and accuracy of adjustment: the cooperation of the spring and the threaded groove allows the operator to conveniently adjust the initial length and elastic pre-tightening force of the lifting rod 211 without the need for complex disassembly and replacement of parts, improving the equipment debugging efficiency. The cooperation of the plug rod 7 and the plug hole 9 facilitates spring adjustment while effectively preventing spring position changes, ensuring the accuracy of clamping during long-term use, reducing welding quality fluctuations caused by clamping errors, and improving product consistency and pass rate.

[0051] Improve the versatility and flexibility of the equipment: the design of the elastic rubber stud on the lower clamping plate 27 allows the length of the lower clamping plate to be flexibly adjusted to adapt to the clamping needs of electronic components of different sizes, further enhancing the versatility of the automatic soldering machine. The stud made of elastic rubber material can provide sufficient clamping force when compressing the component, and can also avoid damaging the surface of the component, protecting the integrity of the component, and is suitable for electronic components of various materials, improving the flexibility and practicality of the equipment in different production scenarios.

[0052] The working principle of the present application is:

[0053] In operation, the first screw rod 213 is driven to rotate by the starting motor 23, the first screw sleeve 214 at both ends and the upper clamping plate 26 are synchronously close until the upper clamping plate 26 clamps the upper part of the electronic component body 5, then the lifting plate 25, the lifting rod 211 and the rack 29 are driven to move downward by the starting first electric push rod 24, the rack 29 drives the gear 28 and the lower clamping plate 27 to rotate, the lower clamping plate 27 clamps the lower part of the electronic component body 5, the upper clamping plate 26 and the lower clamping plate 27 realize stable clamping of the electronic component body 5, avoiding displacement in the welding process, then the mounting frame 33 and the soldering head 4 are driven to move horizontally by the electric sliding block 32, the position of the soldering head 4 is adjusted, and the soldering head 4 is moved to the welding position, after reaching the position, the soldering head 4 is driven to move downward by the second electric push rod 34 to perform soldering operation, through the cooperation of the fixing mechanism 2 and the adjusting mechanism 3, the automatic soldering work of the electronic component can be efficiently and accurately completed.

[0054] In summary: the automatic soldering machine for electronic component production can accurately move the soldering head 4 to the position where the electronic component body 5 needs to be welded through the cooperation of the electric sliding block 32 and the second electric push rod 34, realizes automatic welding, and clamps the upper part and the lower part of the electronic component body 5 through the upper clamping plate 26 and the lower clamping plate 27 respectively, compared with the traditional single clamping plate clamping, this setting can significantly improve the stability of the electronic component body 5 with a non-planar side surface in the welding process, and further improve the welding quality.
