During the tinning process, the material grabber 410 is driven by the mobile driving component 420 to move along the tinning track 500, so that the pins of the electronic components first move horizontally in the solder for a distance, and then are lifted up in an arc to leave the solder tank 310. By moving in a straight line in the solder, the residue on the pins, such as paint film, etc., can be left in the solder tank 310 with the tin flow; and by the arc-shaped lifting action, using the centrifugal principle, the excess solder will not be brought up, and the solder is not easy to stick between the pins, avoiding the pin short circuit; the above-mentioned tinning machine structure can improve the tinning quality of electronic components.

[0038] In the embodiment, the tin supply device 300 is a device for providing molten solder, and a heating device can be provided to ensure that the solder in the solder tank 310 is in a liquid state. It can be understood that there are many embodiments of the device for providing molten solder in the art, and the specific implementation can refer to the existing structure.
[0039] In the embodiment, it also includes a flux supply device 600 and a preheating component 700. The flux supply device 600 is provided with a flux tank 610, and the preheating component 700 is provided with a preheating heating device. The moving driving component 420 is configured to drive the material picking hand 410 to move to the flux tank 610 and the preheating heating device.

[0043] When the picker 410 adopts a magnetic structure, it can pick up some electronic components with iron parts, such as network transformers, etc. After the electronic components are tinned, the picker 410 moves to the workpiece unloading position and places the entire row of electronic components at the workpiece unloading position. The pressing member 821 is driven to approach each other by the pressing driver 822, so that the workpiece pressing surface of the pressing member 821 presses the pins on both sides of the electronic component or the body of the electronic component. Then the picker 410 moves upward, and the magnetically attracted electronic components can stay at the workpiece unloading position, completing the unloading of the electronic components.

The clamping member 221 and the pressing member 821 include a transverse plate, and the end surface of the side where the transverse plate is close to each other is used as the clamping plane, and the lower end surface of the transverse plate is used as the workpiece pressing surface, so that the structures of the clamping member 221 and the pressing member 821 can be unified, allowing the two to be the same part, which is convenient for manufacturing and production.
[0046] In the embodiment, the clamping member 221 and the pressing member 821 further include a vertical plate.

Of course, it is conceivable that the clamping driver 222 and the pressing driver 822 are not limited to the use of cylinder fingers, for example, a screw mechanism can also be used, by providing two screw nuts with opposite rotation directions to respectively connect the two clamping members 221 and the two pressing members 821, and when the screw rotates forward and backward, the two clamping members 221 and the two pressing members 821 can be driven to approach and move away from each other; it can be understood that in this field, there are many implementation methods for the drive structure to achieve the approach and movement of two components, and those skilled in the art can configure it according to actual conditions.
[0048] In the embodiment, the pick-up hand 410 is a magnetic structure and can grab a whole row of electronic components, which can be achieved by setting a row of magnets on the pick-up hand 410, or setting a bar magnet. Of course, it is understandable that for some electronic components that cannot be magnetically attracted, the pick-up hand 410 can adopt other embodiments, such as some clamps, vacuum suction cups, etc.

The conveyor belt is tensioned on a synchronous wheel set, and the motor drives the synchronous wheel to rotate, thereby driving the conveyor belt to perform circular motion.
[0052] It is conceivable that in some embodiments, the loading seat 210 and the unloading seat 810 may not need to form a loading conveyor and a unloading conveyor to receive and convey the workpieces. For example, a pushing mechanism may be provided to realize the input and output of the workpieces on the loading seat 210 and the unloading seat 810.
[0053] In the embodiment, the workpiece loading position and the solder tank 310 are arranged front and back, and the material picker 410 is configured to move in the upper space of the workpiece loading position and the solder tank 310.

[0057] In the embodiment, the mobile drive assembly 420 is specifically configured with a lifting drive 424. After the picker 410 moves to the corresponding process device, it descends to approach the corresponding device components to implement the processes of picking up and placing electronic components, applying flux, preheating, tinning, etc. It is conceivable that in some embodiments, the mobile drive assembly 420 may not be provided with a lifting drive 424, but by providing a lifting structure for each process device to approach the workpiece, so that the corresponding process operation can also be implemented.
