Description

Technical Field

[0002] In industrial production, workpieces need to be glued, such as some circuit boards, lamp holders and products that need to be bonded. During processing, glue needs to be applied to the products so that the products can flow to the next process location for assembly. In order to ensure that the products can be evenly coated with glue, precision glue spraying equipment is required to ensure the processing effect of the products.

[0003] The current method of spraying glue on products is to place the products on processing equipment, then control the glue spraying equipment to move to just above the products, and then control the glue spraying equipment to spray glue on the products. The glue is transported from the conveying equipment and then sprayed out through the glue spraying equipment to achieve gluing of the products.

[0004] Although the above method can spray glue on the product, during the processing, the glue is sucked out by the glue suction machine and transported to the glue spray head through the pipe. After the product is sprayed with glue, there is still glue inside the pipe.

[0036] In a preferred embodiment, a moving block 4 is slidably installed on the positioning frame 2, and one side of the moving block 4 is fixedly connected to the glue spraying head 313, the top of the glue spraying head 313 is fixedly connected to the cylinder 5, the telescopic end of the cylinder 5 is fixedly connected to the plug-in rod 6, and the inner top of the glue spraying head 313 is fixedly connected to the circular electric heating plate 7, the circular electric heating plate 7 is electrically connected to the temperature detector 8, the temperature detector 8 is electrically connected to the PLC controller 9, and the PLC controller 9 is electrically connected to the circular electric heating plate 7.

At the same time, under the action of the temperature detector 8, the temperature inside the glue spraying head 313 is detected to avoid excessive temperature, which will damage the glue and affect the use.

[0037] In a preferred embodiment, the top of the glue storage cylinder 31 is fixedly connected to the rectangular frame 11, and the winding roller 12 is rotatably installed on the inner side of the rectangular frame 11.

In order to facilitate the pulling back of the cleaning block 33 to drive the cleaning block 33 to move, the through hole 16 is provided on the branch pipe 331. The diameter of the through hole 16 is set to be very small in the device, which can be ignored and does not affect the movement of the cleaning block 33 driven by the gas, thereby meeting the requirements of use.

[0039] In order to quickly spray glue and process products, the device is provided with a pressurizing mechanism 20 inside the glue spray head 313. The pressurizing mechanism 20 includes a pressing plate 201, which is slidably installed inside the glue spray head 313. A slide groove 2021 is provided inside the glue spray head 313. The inner wall of one side of the slide groove 2021 is fixedly connected to the spring 202. The sliding block 203 is arranged inside the slide groove 2021. One side of the sliding block 203 is fixedly connected to one end of the spring 202. The other side of the sliding block 203 is fixedly connected to the pressing plate 201. The bottom of the glue spray head 313 is fixedly connected to the glue outlet pipe 21. The inside of the glue outlet pipe 21 is slidably connected to the plug-in rod 6. The inside of the transparent tube 312 is connected to the glue spray head 313. The interior is connected, and the transparent tube 312 is arranged below the pressing plate 201. The glue spraying head 313 is equipped with an air intake mechanism 22, and the air intake mechanism 22 includes an air intake pipe 221 and a control valve 222. One end of the air intake pipe 221 is fixedly connected to the glue spraying head 313, and the other end of the air intake pipe 221 is fixedly connected to the circular tube 321. The control valve 222 is installed outside the air intake pipe 221. In actual use, gas is transported to the inside of the air intake pipe 221 by the blower 32, and the air pressure inside the glue spraying head 313 is increased, so as to push the pressing plate 201 to move downward, thereby pushing the glue inside the glue spraying head 313 to move downward, and the glue can be quickly pressed out from the inside of the glue spraying head 313 to facilitate the glue spraying processing of the product.

[0040] In order to ensure stable processing of the product, the present device has a processing seat 23 fixedly connected to the upper surface of the base 1, the upper surface of the processing seat 23 is slidably connected to the clamping plate 24, the upper surface of the processing seat 23 is fixedly connected to the electric telescopic rod 25, the telescopic end of the electric telescopic rod 25 is fixedly connected to the clamping plate 24, the inner side of the clamping plate 24 is fixedly connected to the rubber pad, a circular groove 27 is provided on the upper surface of the processing seat 23, the inside of the circular groove 27 is fixedly connected to the pressure sensor 26, the pressure sensor 26 is electrically connected to the PLC controller 9, by fixing the pressure sensor 26 inside the processing seat 23, and by the product squeezing the pressure sensor 26, the electric telescopic rod 25 can be controlled by the PLC controller 9 to work, and the clamping plate 24 can be controlled to clamp the product, so that the product can be stably installed on the processing seat 23, and the product can be stably processed.

[0041] In order to meet the needs of use, this device will store a large amount of glue inside the glue storage tube 31. In order to prevent the glue inside the glue storage tube 31 from solidifying, the inner liner 18 is fixedly connected to the inside of the glue storage tube 31, and the glue inlet end of the glue suction machine 311 is fixedly connected to the glue inlet pipe 17. One end of the glue inlet pipe 17 is arranged inside the inner liner 18. The outer surface of the inner liner 18 is fixedly connected to the annular electric heating plate 10. By storing the glue inside the inner liner 18 and continuously heating the inner liner 18 through the annular electric heating plate 10, and controlling the use of the annular electric heating plate 10 through the PLC controller 9, it is avoided that the heating temperature is too high to affect the use, and the glue is in a state close to liquid state, which is convenient for extraction and use at any time.

[0042] Specifically, the working process or working principle of a device for starting precision glue spraying is as follows: the current way of spraying glue on products is to place the product on the processing equipment, then control the glue spraying equipment to move to just above the product, and then control the glue spraying equipment to spray glue on the product. The glue is transported from the conveying equipment and then sprayed out through the glue spraying equipment to achieve gluing of the product.

[0043] Although the above method can be used to spray glue on the product, during processing, the glue is sucked out by the glue suction machine 311 and transported to the position of the glue spray head 313 through the pipeline. After the glue spraying of the product is completed, there is still glue inside the pipeline. If the glue inside the pipeline is not handled in time, it will solidify after a period of time, causing blockage inside the pipeline, thereby affecting subsequent use. Therefore, this device is designed to solve this problem. The external power supply is connected to store the glue inside the glue storage cylinder 31. When gluing the product, the product is placed on the upper surface of the processing seat 23, and the pressure sensor 26 is squeezed so that the pressure sensor 26 detects the presence of pressure. The electric telescopic rod 25 can be controlled by the PLC controller 9 to push the clamping plate 24 to move. The two clamping plates 24 slide on the processing seat 23 to clamp the product, and the product can be stably placed on the upper surface of the processing seat 23 for processing.

[0044] When starting to dispense glue, first extract the glue inside the glue storage cylinder 31 through the glue suction machine 311, and transport the glue to the inside of the glue spray head 313 through the transparent tube 312. In order to prevent the glue from entering the inside of the circular tube 321 and the branch tube 331, the device will install control valves 222 on the circular tube 321 and the branch tube 331 respectively. After the device transports a certain amount of glue to the inside of the glue spray head 313, it stops transporting glue to the inside of the glue spray head 313, and then the glue spray head 313 can be controlled to move, and the glue spray head 313 can be moved to the top of the product, and then the glue spray head 313 can be controlled to spray glue on the product.

[0045] By opening the cylinder 5 and the blower 32, the control valve 222 on the air inlet pipe 221 is opened, the blower 32 absorbs the outside air, and delivers gas to the branch pipe 331, the transparent pipe 312 and the air inlet pipe 221 respectively, and the cleaning block 33 installed in the branch pipe 331 can be blown into the transparent pipe 312 by the gas. The gas in the transparent pipe 312, part of the gas will blow the glue back into the glue suction machine 311, and the other part will blow the cleaning block 33 to move inside the transparent pipe 312. At this time, the telescopic end of the cylinder 5 retracts, and the plug-in rod 6 is pulled out from the glue outlet pipe 2 1 is moved out, at this time, the glue inside the glue spray head 313 will be sprayed out from the inside of the cylinder glue outlet pipe 21 under the action of its own weight. In order to speed up the glue discharge speed, gas is conveyed to the inside of the glue spray head 313 through the air inlet pipe 221. The air pressure inside the glue spray head 313 increases, which will push the pressing plate 201 to move downward, so as to move the glue to discharge quickly. According to the set glue discharge amount, after the glue discharge amount is reached, the cylinder 5 controls the plug-in rod 6 to extend into the inside of the glue outlet pipe 21 to close the glue outlet pipe 21. At this time, the blower 32 should also be stopped to prevent the air pressure inside the glue spray head 313 from being too high and causing danger.

[0046] After the glue spraying process of a product is completed, the product is removed, and then the product to be processed is placed on the processing seat 23, and then the blower 32 and the cylinder 5 are turned on again, and the gas is delivered to the inside of the glue spraying head 313 through the blower 32, so as to increase the internal pressure, press the pressure plate 201 to move downward, and at the same time, when the plug-in rod 6 is separated from the inside of the glue outlet pipe 21, the glue inside the glue spraying head 313 can be sprayed out from the inside of the glue spraying head 313, and at this time, the gas will also be delivered to the inside of the transparent tube 312 and promote the cleaning The block 33 moves inside the transparent tube 312 and pushes the glue inside the transparent tube 312 to move into the glue spray head 313. Since the glue suction machine 311 no longer transports glue to the glue spray head 313, part of the glue inside the transparent tube 312 automatically flows into the glue spray head 313, and the other part flows back into the glue suction machine 311. The amount of residual glue inside the transparent tube 312 is very small, which is not enough to prevent the movement of the cleaning block 33, so the cleaning block 33 can move inside the transparent tube 312.

[0047] Since the outer surface of the cleaning block 33 is fixedly connected to the cleaning brush 14, the cleaning block 33 will clean the inner wall of the transparent tube 312 while moving inside the transparent tube 312, and the glue will adhere to the cleaning brush 14. As the cleaning block 33 continues to move inside the transparent tube 312, until the cleaning block 33 is moved into the glue spraying head 313, there is no glue inside the glue spraying head 313.

[0048] If the product is to be processed further, the winding roller 12 is driven to rotate by the servo motor 15, and the connecting line 13 is wound to pull back the cleaning block 33 and move it back to the initial position, and then the glue suction machine 311 is controlled to extract the glue inside the glue storage cylinder 31 and transport it to the glue spraying head 313, and then the product is processed according to the above method. At the same time, the cleaning block 33 is controlled to move inside the transparent tube 312 to the glue spraying head 313 until the product does not need to be processed, and then cleaning water is introduced into the glue spraying head 313, and the inner wall of the glue spraying head 313 and the cleaning block 33 are rinsed with the cleaning water. After the cleaning block 33 is rinsed clean, the cleaning block 33 is pulled back to the initial position. In this process, the transparent tube 312 can be cleaned again to keep the inside of the transparent tube 312 unobstructed so that it can be used normally later.

[0049] It should be noted that the glue suction machine 311, the cylinder 5, the blower 32, the circular electric heating plate 7, the temperature detector 8, the PLC controller 9, the annular electric heating plate 10, the servo motor 15, the electric telescopic rod 25 and the pressure sensor 26 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
