Description

Technical Field

[0001] This utility model relates to the field of soldering equipment, and more specifically, to an automatic soldering device. Background Technology

[0002] Solder is a low-melting-point metallic solder primarily used for welding electronic components and connecting other metals. It is mainly made of tin-based alloys and possesses excellent electrical conductivity, mechanical strength, and corrosion resistance, making it widely used in the electronics industry, automotive manufacturing, and home appliances. The application of solder typically involves heating the solder material to melt it and then filling the gaps at the joints of the metal parts; a soldering iron is a commonly used tool for this purpose.

[0003] Existing soldering operations are usually done manually with a handheld soldering gun, which has at least the following problems: First, the stability of a handheld soldering gun is poor and it is easily affected by environmental factors, which affects the soldering effect; second, it takes a long time to manually align the soldering tip with the soldering position, resulting in low soldering efficiency, and two people are usually required to complete the soldering of capacitors and resistors. Utility Model Content

[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide an automatic soldering device for improving soldering efficiency.

[0005] This utility model provides an automatic soldering device, including: a worktable, and a first motion mechanism, a second motion mechanism, a soldering tool, and a control component disposed on the worktable;

[0006] The soldering tool is connected to the first motion mechanism via an angle adjustment mechanism, and the first motion mechanism drives the soldering tool to move along the x-axis.

[0007] The first motion mechanism is connected to the second motion mechanism, and the second motion mechanism drives the first motion mechanism to move along the y-axis; the control component is electrically connected to the first motion mechanism, the second motion mechanism, and the soldering tool.

[0008] In this technical solution, the soldering tool is used for soldering operations. An angle adjustment mechanism is used to adjust the rotation angle of the soldering tool, improving its flexibility and adapting to more soldering needs. The soldering tool moves along the x-axis under the drive of the first motion mechanism and along the y-axis under the action of the second motion mechanism. This allows the soldering tool to automatically adjust to the target angle and position under the control of the control components, thereby completing the soldering operation. Compared to manual soldering adjustments, this automatic soldering solution significantly improves soldering efficiency. Furthermore, since manual hand-held soldering can result in shaking or interference from other factors, leading to inaccurate soldering positions, the automatic angle and position adjustment in this solution avoids these problems, improving soldering stability and accuracy. Moreover, since the automatic soldering device in this solution is automatic, it eliminates the training costs associated with manual soldering.

[0009] Furthermore, the workbench is also equipped with fixing components for securing the structure being soldered.

[0010] In this technical solution, a fixing component is used to secure the structure being soldered, preventing displacement of the object during soldering or avoiding instability caused by hand-held shaking, thus ensuring the stability and accuracy of the soldering. Furthermore, without the fixing component, if the object being soldered moves during automatic soldering, repeated manual adjustments are required, which also affects soldering efficiency.

[0011] Furthermore, the fixing component includes a connected resistor fixing member and a capacitor clamp.

[0012] Furthermore, the first motion mechanism includes a first rod frame, a first drive mechanism, a first lead screw, and a first slider; the first lead screw is connected to the first rod frame, the first slider is sleeved on the first lead screw, and the first drive mechanism drives the first lead screw to rotate so as to realize the first slider moving along the x-axis on the first lead screw; the soldering tool is connected to the first slider through an angle adjustment mechanism; the first drive mechanism is electrically connected to the control component.

[0013] Furthermore, the second motion mechanism includes a second rod frame, a second drive mechanism, a second lead screw, and a second slider; the second lead screw is connected to the second rod frame, the second slider is sleeved on the second lead screw, and the second drive mechanism drives the second lead screw to rotate, so as to realize the movement of the second slider along the y-axis on the second lead screw; the first rod frame is connected to the second slider;

[0014] The second drive mechanism is electrically connected to the control component.

[0015] Furthermore, the worktable is also equipped with a reinforcing vertical plate. One end of the bottom of the first rod is connected to the second slider, and the other end is slidably connected to the top of the reinforcing vertical plate. By setting up the reinforcing vertical plate, the first rod is prevented from tilting, thereby improving the accuracy of position control of the soldering tool.

[0016] Furthermore, the angle adjustment mechanism includes an adjustment block, a first bracket, and a second bracket. The adjustment block is rotatably connected to the first motion mechanism via the first bracket, and the adjustment block is rotatably connected to the soldering tool via the second bracket. This simple structure enables angle adjustment of the soldering tool, improving its flexibility.

[0017] Furthermore, the first support includes a first long rod and a first short rod, which are connected to form an "L" shape. The first short rod is rotatably connected to the adjusting block, and the first long rod is fixedly connected to the soldering tool.

[0018] The second support includes a second fixed rod and a second movable rod connected together. The second fixed rod is fixedly connected to the first slider, and the second movable rod is rotatably connected to the adjusting block.

[0019] The second fixed rod is fixedly connected to the first slider, and the second movable rod is rotatably connected to the adjusting block.

[0020] Furthermore, the soldering tool is a soldering gun, which is equipped with a solder feeding device; the control component includes a controller and a switching device, the controller is electrically connected to the first motion mechanism, the second motion mechanism, and the switching device, and the switching device is electrically connected to the solder feeding device to control the start and stop of solder feeding.

[0021] Furthermore, the workbench is also connected to a control panel, allowing the user to operate the control components. This makes soldering operations much more convenient for the user.

[0022] Furthermore, the workbench is also equipped with a cooling device and an exhaust device. The cooling device is used to cool down the soldering tools, and the exhaust device is used for exhaust ventilation.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] (1) Compared with manual adjustment of solder, the automatic soldering of this utility model greatly improves soldering efficiency;

[0025] (2) Since manual soldering with handheld soldering tools may cause shaking or interference from other factors, the soldering position may not be accurate enough. The automatic angle and position adjustment of this utility model can avoid the aforementioned problems and improve the stability and accuracy of soldering.

[0026] (3) Since the automatic soldering device of this utility model is automatic, the training cost of manual soldering can be eliminated.

[0027] (4) The temperature of the soldering tool tip is reduced by setting a cooling device; harmful gases are removed by setting an exhaust device to protect the health of users. Attached Figure Description

This fixing component is positioned on the opposite side of the soldering tool along the x-axis, with the soldering tip of the tool facing the fixing component. By securing the structure to be soldered, the fixing component prevents displacement during the soldering process and avoids instability caused by hand-held shaking, thus ensuring the stability and accuracy of the soldering. Furthermore, without this fixing component, if the object to be soldered moves during automatic soldering, repeated manual adjustments are required, which also affects soldering efficiency.

Specifically, the angle between the base plate 511 and the bevel plate 512 is 50° to 80°, and the clamping portion 522 is inclined, gradually tilting downwards from the direction away from the soldering tool to the direction closer to the soldering tool, with an angle of 20° to 40° with the horizontal plane.

The first rod holder 210 is connected to the second slider 340. The second drive mechanism 320 is electrically connected to the control component. The second slider 340 is matched with the second lead screw 330. For example, both the first drive mechanism 220 and the second drive mechanism 320 are drive motors.

One end of the bottom of the first rod 210 is connected to the second slider 340, and the other end is slidably connected to the top of the reinforcing vertical plate 110. By setting the reinforcing vertical plate 110, the first rod 210 is prevented from tilting, thereby improving the accuracy of position control of the soldering tool.

The controller is electrically connected to the first motion mechanism 200 and the second motion mechanism 300, and the switching device is electrically connected to the solder feeding device to control the start and stop of solder feeding. Specifically, the switching device includes a relay 910 and a driver 920. The solder feeding device includes a synchronous motor. The relay 910 controls the synchronous motor through the driver 920, and the synchronous motor guides the solder wire to the soldering tip. The relay 910 controls the start and stop of solder feeding, thereby controlling the solder feeding time period. Furthermore, the solder gun 400 is also equipped with a switch, an electronic temperature controller, etc. The structure of the solder gun 400 is a common existing structure and will not be described in detail here.

The controller is electrically connected to the switching device, the first drive mechanism 220, and the second drive mechanism 320. Specifically, the control panel 700 is connected to the side of the workbench 100 and has a display on it to show system parameters, making it easier for the user to operate. The control panel 700 is tilted to facilitate viewing the parameters on the display.

[0045] refer to Figure 1 and Figure 4The workbench 100 is also equipped with a cooling device 810 and an exhaust device 820.

Specifically, both the cooling device 810 and the exhaust device 820 are electrically connected to the controller.

The exhaust device 820 is located at the top of the control panel 700, preferably an exhaust fan, to blow harmful gases away from the user and improve safety.

[0046] Example of the automatic soldering device's resistor and capacitor soldering process in this embodiment: The user rotates the solder gun 400 and adjusts it to a suitable angle. The relay 910 is activated via the control panel 700, and deactivates after the solder gun 400 dispenses solder. The first motion mechanism 200 transports the solder gun 400 along the x-axis until the soldering tip is transported to the first straight lead of the capacitor. The relay 910 is activated again, and the solder gun 400 continues to dispense solder before deactivating, soldering one lead of the resistor to the first straight lead of the capacitor.

[0047] The first motion mechanism 200 transports the solder gun 400 along the x-axis, causing it to move back; the second motion mechanism 300 transports the solder gun 400 along the y-axis, the relay 910 is turned on, and after the solder gun 400 dispenses solder, the relay 910 is turned off; the first motion mechanism 200 transports the solder gun 400 along the x-axis, causing it to move forward until the soldering tip is transported to the second straight lead of the capacitor; the relay 910 is turned on, the solder gun 400 continues to dispense solder and then is turned off, soldering the other lead of the resistor to the second straight lead of the capacitor; the first motion mechanism 200 and the second motion mechanism 300 transport the solder gun 400 back to its original position, completing the soldering process.

[0048] Furthermore, in one or more embodiments, the resistance-capacitance soldering process of the automatic soldering device is as follows:

[0049] Relay 910 is activated, and after 1.2 seconds of solder dispensing, it deactivates. The X-axis moves forward by 6.0 microseconds, and the soldering tip is placed on the first 250mm contact pin of the first capacitor for heating. Relay 910 is activated again, and after 10 seconds of solder dispensing, it deactivates. One lead of the resistor is soldered to the first contact pin. The X-axis moves backward by 6.0 microseconds, and the Y-axis moves to the right by 6.5 microseconds. Relay 910 is activated again, and after 1.2 seconds of solder dispensing, it deactivates. The X-axis moves forward by 6.0 microseconds, and the soldering tip is placed on the second 250mm contact pin of the capacitor for heating. Relay 910 is activated again, and after 10 seconds of solder dispensing, it deactivates. The other lead of the resistor is soldered to the second contact pin. The X-axis moves backward by 6.0 microseconds, and the Y-axis moves to the left by 6.5 microseconds. The soldering machine then automatically stops.

[0050] The entire process took 25 seconds and could be completed by one person. Compared to the traditional method which requires two people and takes 40 seconds, this automatic soldering device greatly improves soldering efficiency and saves manpower.
