Description

Technical Field

[0001] The present application relates to the field of dispensing equipment, and in particular to a rapid replacement structure for a glue cylinder of a spraying glue equipment. Background Art

[0002] Since most industrial glues are toxic to the human body, and dispensing is a process with high precision requirements, which requires operators to be in close contact for a long time. To ensure the safety of operators and improve processing efficiency, more and more enterprises begin to use dispensing equipment to replace manual labor.

[0003] There are various types of dispensing equipment. Among them, for dispensing equipment with extremely high precision requirements, the impact needle type dispensing method is also adopted for production and processing. Impact needle type dispensing is a commonly used dispensing method, which uses an impact structure and can quickly and accurately complete the dispensing work. At the same time, it can perform dispensing processing on some extremely small electronic components.

[0004] However, the installation position of the conventional glue cylinder on the equipment is relatively narrow, so it is difficult to fit the glue cylinder onto the equipment, resulting in inconvenient installation and disassembly of the glue cylinder, so it needs to be improved. Summary of the Utility Model

[0005] In order to improve the problem of inconvenient installation and disassembly of the glue cylinder, the present application provides a rapid replacement structure for a glue cylinder of a spraying glue equipment.

[0006] The rapid replacement structure for a glue cylinder of a spraying glue equipment provided by the present application adopts the following technical solutions:

[0007] A rapid replacement structure for a glue cylinder of a spraying glue equipment includes an installation shell, a glue cylinder and a cylinder. The glue cylinder is inserted into the installation shell. An outlet for the glue is opened at one end of the glue cylinder. The cylinder is arranged on the installation shell, and a pressing block is fixed at the output end of the cylinder. The pressing block abuts against the end of the glue cylinder away from the outlet for the glue, and is used for fixing the glue cylinder on the installation shell.

[0008] By adopting the above technical solutions, during installation, place the glue cylinder filled with glue into the installation shell, and then start the cylinder to drive the pressing block to abut against the glue cylinder, so as to squeeze and fix the glue cylinder in the installation shell, realizing the installation of the glue cylinder. During use, align the outlet for the glue of the glue cylinder with the workpiece to be processed, and the glue in the glue cylinder flows out from the outlet for the glue and drips onto the workpiece to be processed, realizing the dispensing work.

[0009] When the glue in the glue cylinder is used up and the glue cylinder needs to be replaced, start the cylinder to drive the pressing block to move away from the glue cylinder, that is, to separate the pressing block from the glue cylinder, which is convenient for taking out the glue cylinder from the installation shell. Then place a new glue cylinder to complete the rapid replacement of the glue cylinder, which is convenient for improving production efficiency.

[0010] Optionally, a firing pin is inserted into the rubber cylinder. One end of the firing pin can abut against the inner wall of the rubber cylinder and block the glue outlet. The other end of the firing pin is provided with a adapter. One end of the adapter is inserted into the rubber cylinder, and the other end is inserted into the pressing block. The firing pin can move on the adapter in a direction close to or away from the glue outlet.

[0011] By adopting the above technical solution, in the initial state, one end of the firing pin abuts against the inner wall of the rubber cylinder, thereby blocking the glue outlet and preventing the glue in the rubber cylinder from leaking. When dispensing glue is required, the firing pin is driven to move away from the rubber cylinder, that is, one end of the firing pin is separated from the inner wall of the rubber cylinder, so that the glue flows between the firing pin and the glue outlet. Then, the firing pin is driven to reset, that is, the firing pin moves towards the glue outlet, so as to extrude the glue between the firing pin and the glue outlet through the glue outlet and complete rapid glue dispensing.

[0012] Optionally, a magnet is connected to the pressing block through a pushing spring. The pushing spring is used to drive the magnet to attract the end of the firing pin away from the glue outlet. An electromagnet is arranged in the pressing block. When the electromagnet is energized, it is used to drive the magnet to move away from the rubber cylinder and attract the electromagnet.

[0013] By adopting the above technical solution, in the initial state, the magnet moves away from the electromagnet under the action of the pushing spring and attracts the end of the firing pin. When glue dispensing is required, the electromagnet is energized, so that the electromagnet generates magnetism and attracts the magnet towards the electromagnet. During this process, the pushing spring is compressed until the magnet attracts the electromagnet. When the magnet moves, it will adsorb the firing pin and move towards the electromagnet together, so that the firing pin moves away from the glue outlet. Then, the electromagnet is powered off, the pushing spring returns to its original shape, and the magnet is pushed away from the electromagnet, so that the magnet is separated from the electromagnet. At the same time, the firing pin is pushed back to its original position, and the firing pin extrudes the glue from the glue outlet.

[0014] Optionally, a moving groove is formed in the side wall of the mounting shell. A moving rod is inserted into the moving groove. The moving rod is located between the rubber cylinder and the mounting shell, and the moving rod can abut against the side wall of the rubber cylinder. The moving rod can move in the moving groove to push the rubber cylinder out of the mounting shell.

[0015] By adopting the above technical solution, after the rubber cylinder is installed in the mounting shell, the moving rod is located between the rubber cylinder and the mounting shell. When the rubber cylinder needs to be disassembled, the moving rod is moved in the moving groove until the moving rod abuts against the side wall of the rubber cylinder. The moving rod continues to move, thereby pushing the rubber cylinder out of the mounting shell, which is convenient for taking out the rubber cylinder in the narrow space of the mounting shell, so that the rubber cylinder can be replaced in a short time.

[0016] Optionally, a positioning block is sleeved on the moving rod. The positioning block is threadedly connected to the moving rod and can abut against the outer side wall of the mounting shell.

[0017] By adopting the above technical solution, after the rubber cylinder is installed in the mounting shell, the moving rod is located between the rubber cylinder and the mounting shell. At this time, the positioning block is adjusted towards the mounting shell until the positioning block abuts against the outer side wall of the mounting shell. The positioning block presses tightly against the mounting shell, so that the moving rod cannot move on the mounting shell, increasing the stability of the moving rod placed on the mounting shell. During the glue dispensing process, the moving rod will not move randomly and collide with the rubber cylinder.

[0018] Optionally, a limiting plate is hinged on the mounting shell. The limiting plate can rotate towards or away from the rubber cylinder. A fixing component is provided on the mounting shell. The limiting plate can be connected to the fixing component for abutting against the side wall of the rubber cylinder.

[0019] By adopting the above technical solution, after the rubber cylinder is inserted into the mounting shell, the limiting plate is rotated towards the rubber cylinder until the limiting plate rotates to the other side of the mounting shell and is connected to the fixing component. At this time, the limiting plate abuts against the side wall of the rubber cylinder, thereby restricting the rubber cylinder in the mounting shell and increasing the stability of the rubber cylinder installed on the mounting shell.

[0020] Optionally, the fixing component includes a fixing block and a limiting block. The fixing block is fixed on the mounting shell. A limiting hole is formed on the side of the fixing block close to the limiting plate. The limiting block is inserted into the limiting hole. The limiting block is connected to the inner wall of the limiting hole through a limiting spring. The limiting spring is used to push the limiting block out of the limiting hole. A mounting hole is formed on the side wall of the limiting plate for the limiting block to be inserted into.

[0021] By adopting the above technical solution, when the end of the limiting plate away from the hinge point between the limiting plate and the mounting shell rotates to the fixing block, the limiting block is pressed into the limiting hole, and the limiting spring deforms, making the side wall of the fixing block protrude, so that the end of the limiting plate can cross over the limiting hole until the mounting hole on the limiting plate aligns with the limiting hole. At this time, the limiting spring restores its deformation, pushes the limiting block out of the limiting hole, and inserts it into the mounting hole. The side wall of the limiting block abuts against the inner wall of the mounting hole, thus playing a limiting role and preventing the limiting plate from moving away from the rubber cylinder, that is, the limiting plate maintains the state of abutting against the rubber cylinder.

[0022] Optionally, a guiding surface is provided on the side of the limiting block away from the mounting shell. The end of the guiding surface away from the limiting spring is inclined towards the mounting shell.

[0023] By adopting the above technical solution, when the end of the limiting plate moves to the fixed block, the limiting block extends out of the limiting hole under the action of the limiting spring, and the end wall of the limiting plate will abut against the guiding surface, and at the same time apply a thrust force moving towards the installation shell to the guiding surface. The inclined setting of the guiding surface plays a guiding role, so that the end of the limiting plate slides relative to the guiding surface, driving the guiding block to squeeze the limiting spring and gradually retract into the limiting hole. When the limiting plate moves to align the installation hole with the limiting block, the limiting block loses its restriction, and the limiting spring resumes its deformation, so that the limiting block extends out of the limiting hole and is inserted into the installation hole, realizing the installation and fixation of the limiting plate and the installation shell.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1. During installation, place the glue cylinder filled with glue in the installation shell, then start the cylinder to drive the pressing block to abut against the glue cylinder, thereby squeezing and fixing the glue cylinder in the installation shell to achieve the installation of the glue cylinder. When in use, align the glue outlet of the glue cylinder with the workpiece to be processed, and the glue in the glue cylinder flows out from the glue outlet and drips onto the workpiece to be processed to achieve the glue dispensing work;

[0026] 2. After the glue cylinder is installed in the installation shell, the moving rod is located between the glue cylinder and the installation shell. When it is necessary to disassemble the glue cylinder, move the moving rod in the moving groove until the moving rod abuts against the side wall of the glue cylinder, and continue to move the moving rod, thereby pushing the glue cylinder out of the installation shell, which is convenient for taking out the glue cylinder in the narrow space of the installation shell, so that the replacement of the glue cylinder can be completed in a short time.

Detailed implementation manners

[0033] The following further elaborates on this application Figures 1-5 in conjunction with the attached drawings.

[0034] An embodiment of this application discloses a quick replacement structure for the glue cylinder 20 of a glue spraying device. Refer to Figure 1 and Figure 2 . The quick replacement structure for the glue cylinder 20 of the glue spraying device includes a mounting shell 10, a glue cylinder 20, and a cylinder 30. The glue cylinder 20 is filled with glue. The glue cylinder 20 is inserted into the mounting shell 10. One end of the glue cylinder 20 in the length direction extends out of the mounting shell 10 and is provided with a glue outlet 21. A connector 60 is installed at the other end of the glue cylinder 20 in the length direction. A sealing ring is sleeved on the connector 60, and the sealing ring abuts against the inner wall of the glue cylinder 20, so that the connector 60 seals the glue cylinder 20.

[0035] Refer to Figure 1 and Figure 2 . The cylinder 30 is installed in the mounting shell 10 through bolts. A pressing block 40 is fixed to the output end of the cylinder 30. The cylinder 30 can drive the pressing block 40 to move along the length direction of the glue cylinder 20 towards or away from the connector 60. One end of the connector 60 away from the glue cylinder 20 can be inserted into the pressing block 40, and a sealing ring is also sleeved, so that the connector 60 can be fixedly installed on the pressing block 40.

[0036] When the glue cylinder 20 is placed in the mounting shell 10 and the cylinder 30 drives the pressing block 40 to press against the connector 60, the glue cylinder 20 is squeezed and fixed in the mounting shell 10, realizing the installation of the glue cylinder 20.

[0037] Refer to Figure 2 and Figure 3 . An ejector pin 50 is inserted into the glue cylinder 20. The ejector pin 50 is arranged along the length direction of the glue cylinder 20. One end of the ejector pin 50 can abut against the inner wall of the glue cylinder 20 and block the glue outlet 21, while the other end of the ejector pin 50 passes through the connector 60 and can move along the length direction of the glue cylinder 20 on the connector 60. A magnet 70 is connected in the pressing block 40 through a pushing spring 71. The pushing spring 71 is used to drive the magnet 70 to attract the end of the ejector pin 50 away from the glue outlet 21. An electromagnet 80 is arranged in the pressing block 40, and the electromagnet 80 is located on the side of the magnet 70 away from the ejector pin 50.

[0038] In the initial state, one end of the firing pin 50 abuts against the inner wall of the glue cylinder 20, thereby blocking the glue outlet 21 and preventing the glue in the glue cylinder 20 from leaking out. The magnet 70 is attracted by the pushing spring 71 and moves away from the electromagnet 80 and attracts to the end of the firing pin 50.

[0039] When dispensing glue is required, the electromagnet 80 is powered on, causing the electromagnet 80 to generate magnetism and attract the magnet 70 towards the electromagnet 80. During this process, the pushing spring 71 is compressed until the magnet 70 attracts to the electromagnet 80. When the magnet 70 moves, it will adsorb the firing pin 50 and move towards the electromagnet 80 together, so that the firing pin 50 moves away from the glue outlet 21, that is, one end of the firing pin 50 separates from the inner wall of the glue cylinder 20, allowing the glue to flow between the firing pin 50 and the glue outlet 21.

[0040] Subsequently, the electromagnet 80 is powered off, the pushing spring 71 restores its deformation, and pushes the magnet 70 away from the electromagnet 80, causing the magnet 70 to separate from the electromagnet 80. At the same time, the firing pin 50 is pushed back to its original position, that is, the firing pin 50 moves towards the glue outlet 21, thereby squeezing the glue between the firing pin 50 and the glue outlet 21 out of the glue cylinder 20 through the glue outlet 21 to complete rapid glue dispensing.

[0041] Refer to Figure 1 and Figure 4 When the glue in the glue cylinder 20 is used up and the glue cylinder 20 needs to be replaced, for the convenience of disassembling the glue cylinder 20, moving grooves 11 are correspondingly opened on the opposite side walls of the installation shell 10. A moving rod 90 is inserted through the moving grooves 11. The moving rod 90 is located between the glue cylinder 20 and the installation shell 10. The moving rod 90 can move in the moving grooves 11 and abut against the side wall of the glue cylinder 20 to push the glue cylinder 20 out of the installation shell 10. A positioning block 91 is sleeved on the part of the moving rod 90 extending out of the installation shell 10. The positioning block 91 is threadedly connected to the moving rod 90, and the positioning block 91 can abut against the outer side wall of the installation shell 10.

[0042] After the glue cylinder 20 is installed in the installation shell 10, the moving rod 90 is located between the glue cylinder 20 and the installation shell 10. At this time, the positioning block 91 is adjusted towards the installation shell 10 until the positioning block 91 abuts against the outer side wall of the installation shell 10. The positioning block 91 is tightly pressed against the installation shell 10, thereby preventing the moving rod 90 from moving on the installation shell 10, increasing the stability of the moving rod 90 on the installation shell 10, and ensuring that the moving rod 90 will not move randomly and collide with the glue cylinder 20 during the glue dispensing process.

[0043] Refer to Figure 1 and Figure 4When the rubber cartridge 20 needs to be removed, the positioning block 91 is adjusted in a direction away from the mounting shell 10 so that the positioning block 91 is separated from the mounting shell 10, and then the moving rod 90 is driven to move in the moving groove 11 until the moving rod 90 abuts against the side wall of the rubber cartridge 20, and the moving rod 90 continues to move, thereby pushing the rubber cartridge 20 out of the mounting shell 10, making it easy to take out the rubber cartridge 20 in the narrow space of the mounting shell 10, so that the replacement of the rubber cartridge 20 can be completed in a shorter time.

[0044] At the same time, since the moving rod 90 abuts against the middle of the rubber cylinder 20, the end of the rubber cylinder 20 can also be directly pressed, so that the rubber cylinder 20 is flipped with the moving rod 90 as a fulcrum, that is, the other end of the rubber cylinder 20 is tilted away from the mounting shell 10, making it easier to remove the rubber cylinder 20 from the mounting shell 10.

[0045] Reference Figure 4 and Figure 5 In order to increase the stability of the rubber cartridge 20 installed in the mounting shell 10, a limit plate 120 is hingedly connected to one side of the mounting shell 10 through a rotating shaft, and the limit plate 120 can rotate in the direction close to or away from the rubber cartridge 20. A fixing assembly 130 is provided on the other side of the mounting shell 10. The fixing assembly 130 includes a fixing block 131 and a limit block 132. The fixing block 131 is fixed to the mounting shell 10. A limit hole 1311 is provided on the side of the fixing block 131 close to the limit plate 120. The limit block 132 is inserted into the limit hole 1311. A limit spring 1321 is provided in the limit hole 1311. One end of the limit spring 1321 is fixed to the inner wall of the limit hole 1311, and the other end is fixed to the limit block 132. The limit spring 1321 is used to push the limit block 132 out of the limit hole 1311. A power limit block 132 is provided on the side wall of the limit plate 120 and is inserted into the mounting hole 121.

[0046] Reference Figure 4 and Figure 5, for the convenience of inserting the limit block 132 into the installation hole 121, a guiding surface 1322 is cut on the side of the limit block 132 away from the installation shell 10. One end of the guiding surface 1322 away from the limit spring 1321 is inclined towards the direction close to the installation shell 10. After the rubber cylinder 20 is placed in the installation shell 10, the limit plate 120 is rotated towards the direction close to the installation shell 10. When the end of the limit plate 120 away from the rotating shaft rotates to the fixed block 131, the limit block 132 extends out of the limit hole 1311 under the action of the limit spring 1321. The end wall of the limit plate 120 will abut against the guiding surface 1322, and at the same time exert a thrust force on the guiding surface 1322 to move towards the installation shell 10. The inclined setting of the guiding surface 1322 plays a guiding role, so that the end of the limit plate 120 slides relative to the guiding surface 1322, driving the guiding block to squeeze the limit spring 1321 and gradually retract into the limit hole 1311. When the limit plate 120 moves to align the installation hole 121 with the limit block 132, the limit block 132 is no longer restricted, and the limit spring 1321 resumes deformation, so that the limit block 132 extends out of the limit hole 1311 and is inserted into the installation hole 121, realizing the installation and fixation of the limit plate 120 and the installation shell 10.

[0047] Referring to Figure 4 and Figure 5 , and then when the rubber cylinder 20 needs to be disassembled, that is, the limit plate 120 needs to be opened first. A pull rod 1323 is fixed at the end of the limit block 132 inserted into the limit hole 1311. The end of the pull rod 1323 away from the limit block 132 extends out of the fixed block 131. By pulling the pull rod 1323, the limit block 132 can be received in the limit hole 1311, so that the limit plate 120 can move freely without restriction.

[0048] The implementation principle of the quick replacement structure of the rubber cylinder 20 of a glue spraying device according to an embodiment of the present application is as follows: during installation, the rubber cylinder 20 filled with glue is placed in the installation shell 10, and then the air cylinder 30 is started to drive the pressing block 40 to abut against the rubber cylinder 20, so as to squeeze and fix the rubber cylinder 20 in the installation shell 10, realizing the installation of the rubber cylinder 20. During use, the glue outlet 21 of the rubber cylinder 20 is aligned with the workpiece to be processed, and the glue in the rubber cylinder 20 flows out from the glue outlet 21 and drips on the workpiece to be processed, realizing the dispensing work;

[0049] When the glue in the rubber cylinder 20 is used up and the rubber cylinder 20 needs to be replaced, the air cylinder 30 is started to drive the pressing block 40 to move away from the rubber cylinder 20, that is, to separate the pressing block 40 from the rubber cylinder 20, so as to facilitate taking out the rubber cylinder 20 from the installation shell 10. Then a new rubber cylinder 20 is placed to complete the quick replacement of the rubber cylinder 20, which is convenient for improving production efficiency.

[0050] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
