Description
Technical Field
[0001] This invention relates to the field of chemical filling technology, and in particular to a clean automatic filling gun and gun holder for barrel-type wet electronic chemicals. Background Technology
[0002] Most wet electronic chemicals in China are corrosive, highly oxidizing, or flammable and explosive. At the same time, the filling of wet electronic chemicals requires a high level of cleanliness (generally using closed clean filling, Class 100 or Class 1000 dust-free levels). Therefore, in China, drummed wet electronic chemicals are generally filled in a closed, automatic, and clean manner, with independent clean automatic filling stations set up to meet the requirements of environmental protection, operational safety (no leakage), and personnel health.
[0003] During the automated filling process of existing drummed wet electronic chemicals, corrosive exhaust gases are often generated. Most existing automated filling stations are equipped with exhaust systems at the top to extract and treat these gases. However, the exhaust vents of these systems are usually quite far from the filling guns within the station. Therefore, when filling the drums with wet electronic chemicals using the filling guns, the corrosive exhaust gases initially escape before being drawn in by the exhaust system. This can negatively impact the system's effectiveness in extracting the gases, potentially leaving some untreated corrosive gases and compromising the safety of the wet electronic chemical filling process. Summary of the Invention
[0004] In order to improve the suction effect of corrosive exhaust gas generated during the filling process of wet electronic chemicals, thereby improving the safety of the filling process, this application provides a clean automatic filling gun and gun holder for barrel-type wet electronic chemicals.
[0005] This application provides a clean automatic filling gun and gun holder for barrelled wet electronic chemicals, adopting the following technical solution:
[0006] An automatic filling gun and gun holder for clean wet electronic chemicals in drums includes a filling gun and a gun holder for locking and fixing the filling gun. A telescopic movable arm is provided on the side wall of the gun holder. A drive mechanism for moving the movable arm as a whole is provided on the gun holder. A female retaining seat is provided at the end of the movable arm away from the gun holder. The filling gun is locked and fixed to the female retaining seat. A gas baffle for preventing the escape of corrosive exhaust gas is provided on the female retaining seat. The movable arm is hollow inside and communicates with the gas baffle. A communication structure for connecting the movable arm to an external exhaust system is provided on the gun holder.
[0007] By adopting the above technical solution, during the filling process of wet electronic chemicals, the baffle is connected to the external exhaust system via a moving arm and a connecting structure. This facilitates the creation of negative pressure at the baffle by the exhaust system, thereby helping to remove corrosive exhaust gases generated during the filling process. This improves the suction effect of corrosive exhaust gases during the filling of wet electronic chemicals, thus enhancing the safety of the filling process. The moving arm and drive mechanism facilitate the movement of the filling gun in both horizontal and vertical directions, thereby helping to adjust the filling position of the filling gun and improving the convenience of filling multiple filling containers with wet electronic chemicals. The female locking seat facilitates the locking and fixing of the filling gun to the gun holder, thus improving the stability of the filling gun during the filling process of wet electronic chemicals.
[0008] In one specific implementation scheme, the movable arm includes a fixed outer arm, a movable inner arm, and a telescopic cylinder. A hollow mounting seat is movably disposed on the side wall of the gun base. One end of the fixed outer arm is fixedly connected to the mounting seat. The movable inner arm is movably engaged with and connected to the fixed outer arm. A female mounting seat is fixedly connected to the end of the movable inner arm away from the fixed outer arm. Mounting plates are fixedly disposed on the inner walls of both the fixed outer arm and the movable inner arm. One end of the telescopic cylinder is fixedly connected to the mounting plate inside the fixed outer arm, and the other end of the telescopic cylinder is fixedly connected to the mounting plate inside the movable inner arm. A sealing structure is provided at the end of the fixed outer arm away from the mounting seat to seal the gap between the fixed outer arm and the movable inner arm.
[0009] By employing the above technical solution, the telescopic cylinder drives the movable inner arm to slide within the fixed outer arm, thereby facilitating the adjustment of the horizontal position of the mother card holder, and consequently, the horizontal position of the filling gun. This improves the accuracy of the filling gun's positioning when filling wet electronic chemicals into different filling containers. The sealing structure enhances the sealing effect between the fixed outer arm and the movable inner arm, preventing leakage of corrosive exhaust gases as they pass through these two arms, further improving the safety of the wet electronic chemical filling process.
[0010] In one specific implementation, the sealing structure includes a fixed sleeve, a connector, and a sealing ring. The fixed sleeve is fixedly disposed on the inner wall of the fixed outer arm and its opening faces away from the mounting base. One end of the movable inner arm is slidably disposed inside the fixed sleeve. The connector is fixedly disposed at the end of the movable inner arm located inside the fixed sleeve. The sealing ring is fixedly connected to the connector and is used to seal the gap inside the fixed sleeve.
[0011] By adopting the above technical solution, the use of fixed sleeves and sealing rings helps to seal the gap between the fixed outer arm and the movable inner arm, thereby improving the sealing effect between the fixed outer arm and the movable inner arm, minimizing the leakage of corrosive exhaust gas as it passes through the movable inner arm and the fixed outer arm, and further improving the safety of the wet electronic chemical filling process.
[0012] In one specific implementation, a plurality of abutment rings are fixedly provided on the movable inner arm, and the plurality of abutment rings are spaced apart on the movable inner arm and slide against the inner wall of the fixed sleeve. The fixed outer arm is provided with abutment bolts for abutting the movable inner arm.
[0013] By adopting the above technical solution, several abutment rings help improve the stability of the sliding inner arm within the fixed outer arm. The clamping bolts help to clamp the inner arm, thereby improving the relative positional stability between the inner and outer arms, and consequently, improving the stability of the filling gun's filling position.
[0014] In one specific implementation, the drive mechanism includes a translation component and a lifting component. The translation component is disposed at the bottom of the gun base and is used to drive the gun base to move horizontally. The lifting component is disposed on the side wall of the gun base and is used to drive the mounting base to move vertically.
[0015] By adopting the above technical solution, the translation component helps to move the filling gun horizontally, and the lifting component helps to move the filling gun vertically. Thus, the combined action of the translation component and the lifting component helps to adjust the filling position of the filling gun, which helps to improve the convenience of filling wet electronic chemicals into multiple filling barrels.
[0016] In one specific implementation, the translation assembly includes a fixed base, a motor, a threaded rod, a support base, and a guide rod. The fixed base is fixedly mounted on the ground, the motor is fixedly mounted on the fixed base, the threaded rod is rotatably mounted within the fixed base and fixedly connected to the output end of the motor, the guide rod is fixedly mounted within the fixed base and parallel to the threaded rod, the support base is threadedly connected to the threaded rod and slidably connected to the guide rod, and the gun mount is fixedly mounted on the support base.
[0017] By adopting the above technical solution, the screw rod is rotated by the electric motor. Under the guidance and limiting action of the guide rod, the fixed seat can move horizontally along the length of the screw rod. This helps to move the gun holder and the filling gun in the horizontal direction, which helps to adjust the filling position of the filling gun in the horizontal direction and improves the accuracy of the filling position of the filling gun.
[0018] In one specific implementation, the lifting assembly includes a drive motor, a transmission gear, a rack, and a guide rail. The drive motor is fixedly mounted on the side wall of the gun base. The transmission gear is fixedly connected to the output end of the drive motor. The guide rail is vertically fixedly mounted on the side wall of the gun base away from the drive motor. The mounting base is slidably engaged with the guide rail. The rack is fixedly mounted on the mounting base and meshes with the transmission gear.
[0019] By adopting the above technical solution, the drive motor drives the transmission gear to rotate. Under the meshing action of the rack and the transmission gear, the mounting base can be vertically raised and lowered along the length of the guide rail. This helps to move the filling gun in the vertical direction, adjust the filling position of the filling gun in the vertical direction, and improve the accuracy of the filling position of the filling gun.
[0020] In one specific implementation, the filling gun is provided with a pneumatic switch valve for controlling the opening and closing of the filling gun, and a snap-fit base plate is fixedly provided at the bottom of the pneumatic switch valve, and the snap-fit base plate is snap-fitted onto the female retainer.
[0021] By adopting the above technical solution, the pneumatic switching valve has advantages such as simple structure, convenient maintenance, high reliability, and fast response speed. Using a pneumatic switching valve helps improve the control effect of opening and closing the filling gun. The snap-fit base plate helps to fix the filling gun to the female mounting base, thereby improving the stability of the relative position between the filling gun and the mounting base.
[0022] In one specific implementation scheme, a fixing ring is fixedly sleeved around the circumference of the filling gun. An air chamber and several air holes are provided inside the fixing ring. The top ends of the air holes are all connected to the air chamber. The filling gun is provided with several communication ports for communicating with the bottom ends of the air holes. A quick-connect connector is provided on the fixing ring. The quick-connect connector is connected to the air chamber and is used to connect to an external air source.
[0023] By adopting the above technical solution, after the filling gun is filled, the external high-pressure air source is connected by the quick-connect connector. The external high-pressure gas is blown into the filling gun through the air chamber and several air holes, which helps to purge the liquid remaining inside the filling gun, helps to prevent the liquid remaining inside the filling gun from dripping during the movement of the filling gun, and helps to improve the safety of the filling gun.
[0024] In one specific implementation, a snap-fit block is provided at the bottom of the female card holder, and a circular hole is provided on the snap-fit block for the filling gun to pass through. A pressure relief hole is provided through the snap-fit block, and the diameter of the pressure relief hole gradually decreases in the direction away from the female card holder. A pressure relief pipe is snapped and fixed at the end of the pressure relief hole near the female card holder, and the end of the pressure relief pipe away from the snap-fit block is located inside the air baffle. A connecting spring is fixedly connected to the end of the pressure relief pipe located inside the pressure relief hole, and a sealing ball for sealing the pressure relief hole is fixedly connected to the end of the connecting spring away from the pressure relief pipe.
[0025] By adopting the above technical solution, during the filling process of wet electronic chemicals, the snap-fit block seals the opening of the filling container, which helps prevent corrosive gases inside the container from escaping outwards. As the internal pressure of the filling container gradually increases, the corrosive gases inside the container exert an upward thrust on the sealing ball in the pressure relief hole, causing the connecting spring to contract and thus releasing the sealing ball's blocking effect on the pressure relief hole. This allows the corrosive gases inside the container to be discharged into the gas baffle through the pressure relief hole and pressure relief pipe, further improving the suction effect of corrosive exhaust gases generated during the filling process of wet electronic chemicals and further enhancing the safety of the filling process.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. This application, through the design of a baffle, a hollow movable arm, and a connecting structure, utilizes the operation of the exhaust system to create negative pressure at the baffle during the filling of wet electronic chemicals. This helps to remove corrosive exhaust gases generated during the filling process, thereby improving the suction effect of corrosive exhaust gases generated during the filling of wet electronic chemicals and enhancing the safety of the filling process.
[0028] 2. This application, through the setting of a sealing structure, helps to improve the sealing effect between the fixed outer arm and the movable inner arm, thereby helping to prevent the leakage of corrosive exhaust gas during the process of passing through the movable inner arm and the fixed outer arm, and further improving the safety of the wet electronic chemical filling process.
[0029] 3. This application utilizes a snap-fit block, a pressure relief pipe, a connecting spring, and a sealing ball. The snap-fit block helps to lock and seal the opening of the filling container, and the sealing ball helps to seal the pressure relief hole, thereby preventing corrosive gases inside the filling container from escaping from the opening. The pressure relief pipe allows corrosive gases inside the container to be directly discharged into the gas baffle, further improving the suction effect of corrosive exhaust gases generated during the filling of wet electronic chemicals and further enhancing the safety of the filling process.

[0037] Reference Figure 1 and Figure 2 The drive mechanism also includes a lifting assembly 12, which includes a drive motor 121, a transmission gear 122, a rack 123, and two guide rails 124. The drive motor 121 is fixedly mounted on the side wall of the gun base 2. The transmission gear 122 is fixedly connected to the output end of the drive motor 121. The two guide rails 124 are vertically fixedly mounted on the side wall of the gun base 2 away from the drive motor 121. A hollow mounting base 26 is slidably engaged on the two guide rails 124. A connecting structure 6 is fixedly connected to the bottom of the mounting base 26, and the connecting structure 6 is connected to an external ventilation system. A placement opening is provided through the gun base 2. The rack 123 is fixedly mounted on the side wall of the mounting base 26 facing the drive motor 121 and located inside the placement opening. The rack 123 meshes with the transmission gear 122.
[0038] Reference Figure 2 and Figure 3 A movable arm 3 is provided on the side wall of the mounting base 26. The movable arm 3 includes a fixed outer arm 31, a movable inner arm 32, and a telescopic cylinder 33. One end of the fixed outer arm 31 is fixedly connected to the mounting base 26. The movable inner arm 32 is slidably engaged with and connected to the fixed outer arm 31. A female retainer 4 is fixedly installed at the end of the movable inner arm 32 away from the fixed outer arm 31. A pneumatic switch valve 13 is fixedly provided on the filling gun 1. A retaining base plate 14 is fixedly connected to the bottom of the switch valve.

Mounting plates 7 are fixedly connected to the inner wall of the fixed outer arm 31 near the gun base 2 and the inner wall of the movable inner arm away from the gun base 2. The two ends of the telescopic cylinder 33 are fixedly connected to the two mounting plates 7 respectively.
[0039] Reference Figure 3A sealing structure 8 is provided on both the fixed outer arm 31 and the movable inner arm 32. The sealing structure 8 includes a fixed sleeve 81, a connector 82 and a sealing ring 83. The fixed sleeve 81 is fixedly installed on the circumferential inner wall of the fixed outer arm 31 and its opening is set in a direction away from the mounting base 26. One end of the movable inner arm 32 is slidably engaged in the fixed sleeve 81. The connector 82 is fixedly installed on the end of the movable inner arm 32 located in the fixed sleeve 81. The sealing ring 83 is fixedly connected to the connector 82.
[0040] Reference Figure 3 Several abutment rings 9 are fixedly installed at intervals on both the outer and inner circumferential sides of the movable inner arm 32, and each abutment ring 9 slides against the inner wall of the fixed sleeve 81. A tightening bolt 10 is threaded through the fixed outer arm 31.
[0041] Reference Figure 1 Before filling wet electronic chemicals, the motor 112 runs, driving the threaded rod 113 to rotate. At the same time, under the guiding and limiting action of the guide rod 115, the fixed seat 111 moves horizontally along the length of the threaded rod 113, which helps to move the gun holder 2 and the filling gun 1 in the horizontal direction, and helps to adjust the filling position of the filling gun 1 in the horizontal direction, thereby improving the accuracy of the filling position of the filling gun 1.
[0042] Reference Figure 2 and Figure 3 When the telescopic cylinder 33 operates, it causes the movable inner arm to slide within the fixed outer arm 31, thereby helping to adjust the horizontal position of the female bracket 4, and consequently the horizontal position of the filling gun 1, further improving the accuracy of the filling position. During the operation of the telescopic cylinder 33, the abutment ring 9 helps to improve the stability of the sliding of the movable inner arm 32 within the fixed outer arm 31. After the telescopic cylinder 33 has completed its operation, the operator manually tightens the abutment bolt 10, which abuts the movable inner arm 32, thereby improving the stability of the relative position between the movable inner arm 32 and the fixed outer arm 31, and enhancing the stability of the filling gun 1 during the filling process.
[0043] Reference Figure 2 The drive motor 121 operates, driving the transmission gear 122 to rotate. Under the meshing action of the rack 123 and the transmission gear 122, the mounting base 26 moves vertically up and down along the length of the guide rail 124, which helps to move the filling gun 1 in the vertical direction, helps to adjust the filling position of the filling gun 1 in the vertical direction, and further improves the accuracy of the filling position of the filling gun 1.
[0044] Reference Figure 2 and Figure 3A locking block 20 is fixedly connected to the bottom of the female card holder 4. A circular hole 21 is opened through the locking block 20, and the bottom of the filling gun 1 is opened through the circular hole 21. A pressure relief hole 22 is opened through the locking block 20 in the vertical direction. The diameter of the pressure relief hole 22 gradually decreases in the direction away from the female card holder 4. A pressure relief pipe 23 is fixedly locked at the top opening of the pressure relief hole 22. The end of the pressure relief pipe 23 away from the locking block 20 is located inside the air baffle 5. A connecting spring 24 is fixedly connected to the end of the pressure relief pipe 23 located inside the pressure relief hole 22. A sealing ball 25 is fixedly connected to the end of the connecting spring 24 away from the pressure relief pipe 23.
[0045] Reference Figure 2 and Figure 3 When the filling of wet electronic chemicals begins, the snap-fit block 20 snaps and seals the opening of the filling barrel. At the same time, the sealing ball 25, supported by the connecting spring 24, seals the pressure relief hole 22, which helps to prevent corrosive gases inside the filling barrel from escaping from the opening of the filling barrel.
[0046] Reference Figure 2 and Figure 3 As the pressure inside the filling barrel gradually increases, the corrosive gas inside the filling barrel will exert an upward thrust on the sealing ball 25 in the pressure relief hole 22, thereby causing the connecting spring 24 to contract under force, thus releasing the sealing effect of the sealing ball 25 on the pressure relief hole 22. This allows the corrosive gas inside the filling barrel to be discharged into the gas baffle 5 through the pressure relief hole 22 and the pressure relief pipe 23. At the same time, the operation of the exhaust system creates a negative pressure at the gas baffle 5, which helps to draw in the corrosive exhaust gas discharged from the pressure relief pipe 23. The corrosive exhaust gas passes through the gas baffle 5, the movable inner arm 32, the fixed outer arm 31, the mounting base 26, and the connecting structure 6 in sequence before entering the exhaust system. This improves the suction effect of the corrosive exhaust gas generated during the filling of wet electronic chemicals, thereby improving the safety of the filling process of wet electronic chemicals.
[0047] Reference Figure 3 The fixed sleeve 81 and sealing ring 83 help to seal the gap between the fixed outer arm 31 and the movable inner arm 32, thereby improving the sealing effect between the fixed outer arm 31 and the movable inner arm 32, minimizing the leakage of corrosive exhaust gas as it passes through the movable inner arm 32 and the fixed outer arm 31, and further improving the safety of the wet electronic chemical filling process.
[0048] Reference Figure 3 and Figure 4A fixing collar 15 is fixedly sleeved around the periphery of the filling gun 1. The fixing collar 15 has an air chamber 16 and several air holes 17, the tops of which are connected to the air chamber 16. Several connecting ports 18 are provided on the barrel of the filling gun 1, each connecting port 18 being connected to one air hole 17. A quick-connect connector 19 is fixedly installed on the fixing collar 15, and the quick-connect connector 19 is connected to the air chamber 16.
[0049] Reference Figure 3 and Figure 4 After the filling gun 1 is filled, the external high-pressure air source is connected by the quick-connect connector 19. The external high-pressure gas is blown into the filling gun 1 through the air chamber 16 and several air holes 17, which helps to purge the liquid remaining inside the filling gun 1, helps to prevent the liquid remaining inside the filling gun 1 from dripping during the movement of the filling gun 1, and helps to improve the safety of the filling gun 1.
[0050] The implementation principle of this application embodiment is as follows: Before filling wet electronic chemicals, the motor 112 operates, driving the threaded rod 113 to rotate. Simultaneously, under the guiding and limiting action of the guide rod 115, the fixed seat 111 moves horizontally along the length direction of the threaded rod 113, thereby helping to move the gun holder 2 and the filling gun 1 in the horizontal direction, and facilitating the adjustment of the filling position of the filling gun 1 in the horizontal direction. The telescopic cylinder 33 operates, driving the movable inner arm to slide within the fixed outer arm 31, thereby helping to adjust the horizontal position of the female card holder 4, and further facilitating the adjustment of the filling position of the filling gun 1 in the horizontal direction. The drive motor 121 operates, driving the transmission gear 122 to rotate. Under the meshing action of the rack 123 and the transmission gear 122, the mounting seat 26 rises and falls vertically along the length direction of the guide rail 124, thereby helping to move the filling gun 1 in the vertical direction, and facilitating the adjustment of the filling position of the filling gun 1 in the vertical direction.
[0051] When the filling of wet electronic chemicals begins, the snap-fit block 20 snaps and seals the opening of the filling barrel. At the same time, the sealing ball 25, supported by the connecting spring 24, seals the pressure relief hole 22, which helps to prevent corrosive gases inside the filling barrel from escaping from the opening of the filling barrel.
[0052] As the internal pressure of the filling barrel gradually increases, the corrosive gas inside the filling barrel exerts an upward thrust on the sealing ball 25 in the pressure relief hole 22, causing the connecting spring 24 to contract under force. This releases the sealing effect of the sealing ball 25 on the pressure relief hole 22, allowing the corrosive gas inside the filling barrel to be discharged into the baffle 5 through the pressure relief hole 22 and the pressure relief pipe 23. At the same time, the operation of the exhaust system creates a negative pressure at the baffle 5, which helps to draw in the corrosive exhaust gas discharged from the pressure relief pipe 23. The corrosive exhaust gas then passes through the baffle 5, the movable inner arm 32, the fixed outer arm 31, the mounting base 26, and the connecting structure 6 before entering the exhaust system. This improves the suction effect of the corrosive exhaust gas generated during the filling of wet electronic chemicals, thereby improving the safety of the filling process.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
