Abstract
Description
Technical Field
[0001] The invention belongs to the field of soldering equipment, and in particular relates to a tin feeding and breaking device for a soldering machine. Background Art
[0002] At present, automatic soldering equipment is widely used, and the tin feeding device (also called tin feeder) and the tin breaking device (also called tin breaking device) are two main components of the automatic soldering machine. In the prior art, the main function of the tin feeding device is to realize automatic tin feeding, but it does not have the tin breaking function, and the tin breaking device cannot be used as a traditional tin feeder.
[0003] Tin wire (also called tin wire) is a typical soft soldering material in the field of electronics industry and is widely used in welding technologies such as manual soldering, soldering robot soldering and laser soldering. However, since there is flux in the tin wire, the flux will be heated and oxidized during high-temperature soldering, causing high pressure inside the tin wire, resulting in splashing of the tin wire during high-temperature soldering, affecting the welding quality and endangering the personal safety of the operator. In order to prevent the occurrence of the "tin explosion" phenomenon, the tin wire is split or punched through a tin breaking machine so that the flux overflows from the hole, improving the welding environment. The processed tin wire can be wound into a tin coil for use.
[0004] Patent application CN201520425400.7 discloses an automatic tin feeding mechanism, which is installed on a tin soldering machine through a fixed plate, and includes a tin feeding base, a stepper motor, a tin feeding module and a tin discharging module. A cantilever extends from the side of the tin feeding base, and the tin feeding module is installed on the cantilever. A tin wire tube is installed at the tail end of the cantilever; the stepper motor is installed on the bottom surface of the tin feeding base, and its transmission shaft passes through the tin feeding base to connect a driving wheel, and a passive wheel is provided next to the driving wheel, and a gap is left between the passive wheel and the driving wheel; the tin discharging module is fixed It is fixed on the tin feeding base, wherein the tin feeding module and the tin discharging module are located at both ends, and the driving wheel and the passive wheel are located between the tin feeding module and the tin discharging module; the tin feeding module is provided with a fixed tin passing tube, and the tin discharging module is provided with a floating tin passing tube, and the fixed tin passing tube, the gap between the driving wheel and the passive wheel, and the floating tin passing tube are aligned with each other; the tin feeding module is provided with a spring reset induction switch, which is connected to the fixed tin passing tube; the tin discharging module is provided with a spring reset induction switch, which is connected to the floating tin passing tube; an upper cover serving as a protective cover is provided on the tin feeding base.
[0005] The above utility model solves the problem that although the traditional soldering equipment is automated in the soldering process, the automation level in the tin feeding process is not high enough, and when the tin wire runs out, tin is blocked, etc., manual intervention is still required, and the equipment cannot self-identify and solve the problem. However, it does not have the function of breaking tin.
[0006] For another example, patent application CN201720964910.0 discloses a double-sided tin-breaking machine, including a driving wheel, a tin-guiding tube, a first tin-breaking knife and a second tin-breaking knife. The tin-guiding tube is vertically arranged throughout the entire tin-breaking machine, the first tin-breaking knife and the second tin-breaking knife are respectively arranged on both sides of the tin-guiding tube, the driving wheel and the first tin-breaking knife are arranged on the same side of the tin-guiding tube and are engaged with the driven wheel arranged in the first tin-breaking knife, and the driven wheel arranged in the second tin-breaking knife is engaged with the driven wheel arranged in the first tin-breaking knife. The technical solution of this utility model adopts double-sided tin-breaking, which greatly increases the tin-breaking area. Tin-breaking on both sides can make the tin wire melt more evenly. The tin-guiding tube has a horizontal gap from top to bottom, which can effectively reduce the problem of tin sticking. However, it cannot be used as a traditional tin feeder.

[0054] The movable plate 232 is swung by toggling the tensioning handle 231 of the driven wheel, so that the angle of the tin wire driven wheel 21 is rotated to adjust the size of the tin feeding channel or the tin breaking channel 02. The implementation method is simple. After the adjustment, the adjusting knob 234 is rotated to compress the adjusting spring 235, and the side wall of the movable plate 232 and the bottom end of the adjusting screw 236 are respectively abutted against the outer wall of the driving motor 31 and the side wall of the frame 5 to fix the movable plate 232.
[0055] Among them, the movable plate 232 includes a first mounting portion 2321, a connecting portion 2322 and a second mounting portion 2323; the first mounting portion 2321 and the second mounting portion 2323 are respectively connected in one piece on both sides of the connecting portion 2322; the first mounting portion 2321 is installed on the frame 5 through the movable plate mounting column 233, the driven wheel tensioning handle 231 and the driven wheel fixing column 22 are respectively fixedly installed at the front and rear ends of the connecting portion 2322, and the outer side wall of the second mounting portion 2323 is provided with a mounting groove 2324 and a mounting through hole 2325, and the two are arranged side by side; one end of the adjusting spring 235 is fixedly installed in the mounting groove 2324, and the bottom end of the adjusting screw 236 is fixedly installed in the mounting through hole 2325.
[0056] In this embodiment, the device further includes a tin shortage alarm sensing unit 8, which is fixedly mounted on the frame 5 and located on the side of the first guide wheel 111. The tin shortage alarm sensing unit 8 is electrically connected to the driving mechanism 3. The device realizes the tin shortage alarm function by providing the tin shortage alarm sensing unit 8, so that the device can automatically stop when sensing the lack of tin. The tin shortage alarm sensing unit 8 can be a tin shortage alarm sensor.
[0057] The tin deficiency alarm sensing unit 8 can also be a tin wire micro-touch switch. When the tin wire C passes through the device, the tin wire micro-touch switch is in a closed state. When there is no tin wire C (the tin wire is used up), the tin wire micro-touch switch is in an open state, so that the IO signal is sent to the external computer host (the tin deficiency alarm sensing unit can be electrically connected to the external computer host according to the prior art). The computer host will give corresponding actions and early warning prompts, and the tin wire micro-touch switch will inform the drive mechanism 3 to stop working, thereby shutting down the device.
[0058] The advantages of the present invention are:
[0059] Compared with the prior art, the two-in-one twitch-type automatic tin feeding and tin breaking device implemented by the present invention replaces manual labor with machines to realize automatic tin feeding and automatic tin breaking, and switches the tin feeding and tin breaking functions by changing the installation method of the tin feeding and tin breaking mechanism 4. It can be used as a tin breaking device as well as a tin feeding device.
[0060] The device realizes the tin deficiency alarm function by providing a tin deficiency alarm sensing unit 8, so that the device can automatically shut down when sensing tin deficiency; the device can also be connected to a variety of soldering machines by providing a tin delivery conduit 6 and a tin outlet conduit 7, without the need to load tin wire, while reducing the floor space; the device is also suitable for tin wires of different thicknesses, and can reduce the probability of tin jamming and tin gambling caused by tin wire bending and deformation.
[0061] The above lists the preferred embodiments of the present invention, which are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
