DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0020] Embodiments of the present invention: Figure 1-Figure 4 As shown, an automatic glue cleaning device for a glue gun nozzle comprises a glue coating tower 1 and a glue coating gun 2. The lower end of the glue coating tower 1 is fixedly mounted on the ground, and the top of the glue coating tower 1 is fixedly connected with a horizontally arranged glue gun mounting arm 3. The glue coating gun 2 is fixedly mounted at the end of the glue gun mounting arm 3. A lifting mechanism is arranged on the glue coating tower 1, and a glue cleaning frame 4 is mounted on the lifting mechanism, and a glue nozzle cleaning device is fixedly mounted on the glue cleaning frame 4.

[0021] The lifting mechanism is used to control the height of the glue cleaning rack 4. When the glue nozzle on the glue gun 2 needs to be cleaned, the lifting mechanism drives the glue cleaning rack 4 to rise, so that the glue nozzle cleaning device at the end of the glue cleaning rack 4 is connected to the glue nozzle on the glue gun 2, and the glue nozzle is cleaned by the glue nozzle cleaning device. After cleaning, the lifting device drives the glue cleaning rack 4 to move down, so that the glue nozzle cleaning device is separated from the glue nozzle of the glue gun 2, so that the glue gun 2 can work normally.

[0022] In a specific embodiment, the lifting mechanism includes a slide rail 5, a slider 6 and a lifting cylinder 7. The cross-sectional shape of the glue coating tower 1 is a rectangle. One end of the glue gun mounting arm 3 is fixedly connected to the side wall of one side of the glue coating tower 1 by bolts. There are two slide rails 5. The two slide rails 5 and the glue gun mounting arm 3 are fixed on the same side wall of the glue coating tower 1. A slider 6 is slidably installed on each of the two slide rails 5. The two sliders 6 are fixedly connected to the end of the glue cleaning frame 4.

[0023] The two slide rails 5 are arranged parallel and opposite to each other, and the upper ends of the two slide rails 5 extend to the connection position between the glue gun mounting arm 3 and the glue coating tower 1. In this embodiment, position switches (not shown in the figure) are installed at the upper and lower ends of the two slide rails 5, and the glue cleaning rack 4 is a rectangular frame structure, and a PLC programmable controller (not shown in the figure) is arranged inside the glue cleaning rack 4.

[0024] The slide block 6 can only slide along the slide rail 5 and can not be separated from the slide rail 5. The effect of the slide block 6 is to enable the glue cleaning frame 4 to move smoothly on the slide rail 5.

[0025] Furthermore, a mounting seat 8 is fixedly provided on the side wall at the lower end of the glue coating tower 1, and the lifting cylinder 7 is arranged vertically. The lower end of the lifting cylinder 7 is rotatably connected to the mounting seat 8 through a rotating shaft, and the telescopic end of the lifting cylinder 7 is connected to the glue cleaning rack 4. The glue cleaning rack 4 is provided with a second mounting seat 19 for connecting to the telescopic end of the lifting cylinder 7.

[0026] The working state of the lifting cylinder 7 is controlled by the PLC programmable controller. The PLC programmable controller controls the lifting cylinder 7 to extend, and the lifting cylinder 7 pushes the glue cleaning rack 4 to move upward along the slide rail 5. The PLC programmable controller controls the lifting cylinder 7 to contract, and the glue cleaning rack 4 moves downward along the slide rail 5.

[0027] Furthermore, the glue nozzle cleaning device includes a glue cleaning box 9, a waste glue barrel 10 and a purge air separator 11. The glue cleaning box 9 is fixed at the end of the glue cleaning frame 4, the waste glue barrel 10 is fixed in the glue cleaning box 9, the top of the waste glue barrel 10 has a glue inlet, and the purge air separator 11 is fixed on the glue inlet.

[0028] A door 20 is provided on one side of the cleaning box 9, and a handle 21 is provided on the door 20. The door 20 can be opened by the handle 21, so that the waste glue barrel 10 in the cleaning box 9 can be taken out conveniently, so as to pour out the glue liquid in the waste glue barrel 10. In this embodiment, the bottom of the waste glue barrel 10 is fixed to the bottom of the cleaning box 9 by bolts, so that the waste glue barrel 10 is convenient to disassemble and fix.

[0029] The purge air separator block 11 is a toroidal structure, with two opposite air inlet holes on its outer wall, which are connected to the air inlet pipe 12 . The interior of the purge air separator block 11 is a hollow structure, with a plurality of jet holes 13 formed on its top surface.

[0030] The purge gas distributor block 11 is used to blow out high-pressure gas, and the glue stains on the glue nozzle of the glue coating gun 2 are blown off by the high-pressure gas, and the glue stains fall into the waste glue barrel 10 for collection.

[0031] Furthermore, a glue nozzle passage hole is provided on the top plate of the glue cleaning box 9, and the glue nozzle passage hole is opposite to the glue inlet and the two are coaxial. A clamping cylinder 14 is fixedly provided on the top of the top plate of the glue cleaning box 9, and a baffle 16 is fixedly provided on the two clamping jaws 15 of the clamping cylinder 14 respectively. Semicircular grooves 17 are formed on the two baffles 16. When the two baffles 16 are combined, the two semicircular grooves 17 form a circular hole.

[0032] The clamping jaw cylinder 14 is a commercially available component and can be purchased directly. The clamping jaw cylinder 14 is electrically connected to the PLC programmable controller, and the working state is controlled by the PLC programmable controller. When the two clamping jaws 15 on the clamping jaw cylinder 14 are opened, the two baffles 16 are separated. At this time, the glue nozzle on the glue gun 2 can be smoothly inserted into the glue cleaning box 9, and then the clamping jaws 15 are closed, the two baffles 16 are merged, and the glue nozzle is clamped by two semicircular grooves 17, so that the glue will not splash during glue cleaning.

[0033] An air pump 18 is provided inside the cleaning frame 4, and the air pump 18 is used to supply air to the lifting cylinder 7 and the air inlet pipe 12. The air pump 18 is connected to the PLC programmable controller. When the gas stored in the air pump 18 is insufficient, the PLC programmable controller controls the air pump 18 to work and prepare high-pressure gas and store it.

[0034] The working principle of the present invention is as follows: when it is necessary to clean the glue nozzle on the glue coating gun 2, the PLC programmable controller controls the elevating cylinder 7 to extend, and the telescopic end of the elevating cylinder 7 pushes the glue cleaning frame 4 upward. When the glue cleaning frame 4 rises to a preset position along the slide rail 5, it contacts the position switch at the upper end of the slide rail 5. The position switch sends a signal to the PLC programmable controller, and the PLC programmable controller controls the elevating cylinder 7 to stop extending. At this time, the glue nozzle on the glue coating gun 2 passes through the glue nozzle through the hole on the top plate of the glue cleaning box 9 and is aligned with the center of the purge gas distributor block 11. The PLC programmable controller controls the clamping claw cylinder 14 to work, and the two clamping claws 15 on the clamping claw cylinder 14 are closed. At the same time, the two baffles 16 merge, and the two semicircular grooves 17 clamp the upper end of the glue nozzle. The PLC programmable controller controls the air pump 18 to supply air to the air inlet pipe 12, and the high-pressure gas is ejected through the jet hole 13 on the purge gas distributor block 11, purging the glue nozzle 360° to blow off the residual glue on the glue nozzle, and the residual glue falls into the waste glue barrel 10 below by gravity. After the preset purge time, the purge stops. The PLC programmable controller controls the clamping jaw cylinder 14 to open the two clamping jaws 15, and the two baffles 16 are separated from the glue nozzle. Then the PLC programmable controller controls the lifting cylinder 7 to retract. When the glue cleaning rack 4 moves down along the slide rail 5 to the preset position, it contacts the position switch at the lower end of the slide rail 5. The position switch sends a signal to the PLC programmable controller, and the PLC programmable controller controls the lifting cylinder 7 to stop retracting, completing a working cycle and waiting for the next glue cleaning.

[0035] It should be noted that the upper limit position and the lower limit position of the cleaning frame 4 can also be controlled by controlling the extension and contraction of the lifting cylinder 7 through a PLC programmable controller. When this solution is adopted, the position switches at both ends of the slide rail 5 can be eliminated.

[0036] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
