Description

Technical Field

[0001] The present invention relates to the technical field of chemical product sub-packaging, and particularly to a sub-packaging device for an electronic chemical product conveying system. Background Art

[0002] Electronic chemical products refer to high-purity chemical materials applied in the field of the electronics industry, usually used in the manufacture of electronic components such as semiconductors and integrated circuits. They have characteristics such as high purity and stable performance, and belong to the key basic materials in the electronics industry. Reagent-type electronic chemical products include various strong solvents, strong acid and strong base solutions, and strong oxidants, etc. When transporting and sub-packaging them, materials that can resist the above reagents or solutions, such as fluoroplastics, etc., are required;

[0003] During the process of transporting an electronic chemical product solution and sub-packaging it into a container, when the sub-packaging solution quickly passes through narrow channels such as nozzles, turbulence is likely to occur, resulting in the mixing of the solution and air, forming bubbles and finally entering the container interior. Moreover, in the case of the high-speed injection method of direct central injection, the solution will vertically impact the bottom or liquid surface of the container, possibly forming a vortex on the liquid surface in the container and drawing air into the liquid, which will also cause bubbles to be generated in the sub-packaged electronic chemical product solution in the container. Bubbles will not only affect the accuracy of the sub-packaging volume of the electronic chemical product solution, but may also cause defects such as coating bubbles and uneven curing in the subsequent process of the electronic chemical product. Currently, static defoaming or mechanical stirring defoaming methods are often used. However, the static defoaming method has too low efficiency, and the mechanical stirring defoaming method is likely to cause shear stress to the electronic chemical product solution, affecting the performance of the electronic chemical product. Summary of the Invention

[0004] Aiming at the above-mentioned drawbacks of the prior art, the present invention provides a sub-packaging device for an electronic chemical product conveying system, which can effectively solve the problems that bubbles are generated when an electronic chemical product solution is sub-packaged into a container in the prior art, affecting the accuracy of the sub-packaging volume of the container and resulting in defects in the subsequent use of the electronic chemical product solution.

[0010] Further, an electric conveyor belt is fixedly installed inside the pipeline transporter, and a lateral guardrail is fixedly connected to the upper end surface of the pipeline transporter.

[0011] Further, the flow-concentrating component includes a balance bracket fixedly connected to the inner wall of the nozzle.

[0012] Further, limit sliding rails are fixedly connected to the two opposite outer walls of the pipeline transporter. The lower end of the lifting frame is slidably matched with the limit sliding rails. A lifting electric cylinder is fixedly installed at a position close to the lower part of the outer wall of the pipeline transporter. A support top plate is fixedly connected to the outer wall of the lifting frame. The output end of the lifting electric cylinder is fixedly connected to the lower end surface of the support top plate.

[0013] Further, a first displacement sensor, a second displacement sensor and a PLC controller are fixedly installed inside the lifting frame. The first displacement sensor is used to monitor the displacement of the container on the electric conveyor belt. The second displacement sensor is used to monitor the displacement of the two flow-concentrating ball heads. The first displacement sensor, the second displacement sensor, the PLC controller, the lifting electric cylinder, the electric conveyor belt, the delivery pump and an external power supply are electrically connected.

[0014] Further, the rotation driving component includes a rotation motor fixedly installed at the top end of the lifting frame.

[0017] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0018] In the present invention, an adaptive side injection assembly is provided. By driving the rotating frame to rotate and driving the two nozzles to rotate synchronously, the two nozzles can swing obliquely backward due to centrifugal force while rotating, so that the two converging ball heads gradually approach and finally contact the inner wall of the container, enabling the solution injection range of the two nozzles to automatically adapt to the caliber of the container. When filling electronic chemicals into containers of different calibers, there is no need to replace the nozzles, improving the versatility of the filling and injection of electronic chemical solutions.

[0019] In the present invention, a metal hose, a nozzle and a converging component are provided. Since the metal corrugated hose will bend to a certain extent, and the nozzle is in an inclined state relative to the container when the converging ball head contacts the inner wall of the container, the electronic chemical solution can be injected obliquely into the inner wall of the container by the nozzle, so as to avoid the electronic chemical solution from being involved in air due to vertical impact on the bottom or liquid surface of the container. At the same time, the nozzle is in a rotating injection state, so that the solution can be injected into the container in a spiral shape. The centrifugal force can throw the bubbles in the solution to the inner wall of the container, and at the same time, the liquid surface disturbance can be reduced, effectively avoiding the generation of bubbles when the electronic chemical solution is filled into the container, and no shear stress will be generated on the electronic chemical solution, ensuring the performance of the electronic chemical.

[0020] An air suction component is provided in the present invention. When the rotating frame rotates, it can also drive the suction cylinder and the abutting roller to rotate synchronously. The contact rolling cooperation between the abutting roller and the annular corrugated plate and the pulling cooperation of the alloy tension spring can make the reciprocating piston slide reciprocatingly in the suction cylinder, so that the suction cylinder can perform linked suction on the air in the container, so as to perform double real-time defoaming on the solution dispensed into the container, effectively improving the defoaming efficiency of the solution, which is beneficial to ensuring the purity of the electronic chemical solution and the accuracy of the dispensing amount, and avoiding defects in the electronic chemicals in subsequent processes.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Embodiment: Refer to Figures 1 to 8 , a sub-packaging device for an electronic chemical conveying system, comprising: a pipeline transporter 1 and a PVDF conveying pipe 2. An electric conveyor belt 8 is fixedly installed inside the pipeline transporter 1. A side guardrail 9 is fixedly connected to the upper end surface of the pipeline transporter 1. A plurality of adaptive side injection assemblies 3 are slidably arranged on the two opposite outer walls of the pipeline transporter 1; the adaptive side injection assembly 3 includes a lifting frame 31 slidably connected to the two opposite outer walls of the pipeline transporter 1. A conveying pump 32 is fixedly installed at the upper end of the lifting frame 31. The conveying pump 32 adopts a plunger pump. The lower end of the conveying pump 32 is fixedly connected with an annular bearing 33. The outer ring of the annular bearing 33 is fixedly connected with a connecting bracket 34. The outer ring of the annular bearing 33 is rotationally matched with the inner ring of the annular bearing 33, and the inner ring of the annular bearing 33 is fixed to the lower end of the conveying pump 32. The lower ends of a plurality of connecting brackets 34 are fixedly connected with a rotating frame 35. A liquid inlet pipe 36 is fixedly connected to the middle of the rotating frame 35. The inlet end of the liquid inlet pipe 36 is hermetically and rotationally communicated with the outlet end of the conveying pump 32;

[0034] Specifically, the outlet end of the transfer pump 32 and the inlet end of the liquid inlet pipe 36 are rotationally connected in a sealed manner through a sealed bearing. Therefore, when the rotating frame 35 and the liquid inlet pipe 36 rotate relative to the transfer pump 32, the transfer pump 32 can be supported to pump the electronic chemical solution into the liquid inlet pipe 36;

[0035] The outlet end of the liquid inlet pipe 36 is fixedly communicated with a three-way shunt cavity 37. The bottom end of the three-way shunt cavity 37 is fixedly communicated with two metal bellows hoses 38. The outlet ends of the two metal bellows hoses 38 are both fixedly communicated with spray nozzles 39. The outer walls of the two spray nozzles 39 are both fixedly connected with counterweight blocks 310;

[0036] Specifically, the metal bellows hose 38 is made of stainless steel lined with polytetrafluoroethylene plastic. The metal bellows hose 38 supports expansion and bending. When the rotating frame 35 rotates to drive the two spray nozzles 39 to rotate and causes the two spray nozzles 39 to swing obliquely away from each other due to centrifugal force, the metal bellows hose 38 will undergo a certain degree of contraction and bending to support the oblique swing of the spray nozzles 39 due to centrifugal force. The counterweight blocks 310 are fixed to the outer walls of the spray nozzles 39. When the spray nozzles 39 rotate and swing obliquely, the counterweight blocks 310 can increase the overall mass of the spray nozzles 39, thereby increasing the centrifugal force of the spray nozzles 39 when they are moving in a circular motion, that is, rotating. Thus, the speed of the spray nozzles 39 swinging obliquely to the inner wall of the container can be increased, improving the working efficiency. When the rotating frame 35 does not rotate, the metal bellows hose 38 can automatically return to a state perpendicular to the ground under the action of the gravity of the counterweight blocks 310;

[0037] A flow concentrating component 4 is fixedly connected to the inner wall of the spray nozzle 39. The flow concentrating component 4 includes a balance bracket 41 fixedly connected to the inner wall of the spray nozzle 39. A guide rod 42 is fixedly connected to the lower end face of the balance bracket 41. The end of the guide rod 42 located outside the spray nozzle 39 is fixedly connected with a flow concentrating ball head 43. The flow concentrating ball head 43 is made of fluororubber;

[0038] Specifically, the included angle between the spherical surface of the flow concentrating ball head 43 and the outlet of the spray nozzle 39 is 45°. When the electronic chemical solution is sprayed out from the spray nozzle 39, the flow concentrating ball head 43 can restrain the sprayed solution, so that the sprayed solution can form a concentrated flow, increasing the stability of the sprayed solution. Thus, the phenomenon that the solution generates bubbles due to the formation of turbulence can be avoided;

[0039] A rotation driving component 5 is fixedly connected to the top end of the lifting frame 31. The rotation driving component 5 is used to drive the rotating frame 35 to perform a rotational motion. The rotation driving component 5 includes a rotation motor 51 fixedly installed at the top end of the lifting frame 31. The output end of the rotation motor 51 is fixedly connected with a small gear 52. An external gear ring 53 is fixedly connected to the outer wall of the rotating frame 35. The external gear ring 53 meshes with the small gear 52;

[0040] A number of pump pipes 6 are fixedly connected to the circumferential side wall of the PVDF conveying pipe 2 in a circumferential direction. The number of pump pipes 6 are respectively communicated with the liquid inlet ends of a number of conveying pumps 32. Limited position slide rails 10 are fixedly connected to the two opposite outer walls of the assembly line transporter 1. The lower end of the lifting frame 31 is slidably matched with the limited position slide rails 10. A lifting electric cylinder 11 is fixedly installed at a position close to the lower part of the outer wall of the assembly line transporter 1. A support top plate 12 is fixedly connected to the outer wall of the lifting frame 31. The output end of the lifting electric cylinder 11 is fixedly connected to the lower end face of the support top plate 12. A first displacement sensor 13, a second displacement sensor 14 and a PLC controller 15 are fixedly installed inside the lifting frame 31;

[0041] Specifically, the first displacement sensor 13 is used to monitor the displacement of the container on the electric conveyor belt 8, and the second displacement sensor 14 is used to monitor the displacement of the two converging ball heads 43. The first displacement sensor 13, the second displacement sensor 14, the PLC controller 15, the lifting electric cylinder 11, the electric conveyor belt 8, and the conveying pump 32 are electrically connected to an external power supply. The PLC controller 15 adjusts the rotation speed of the rotation motor 51 according to the displacement signal of the converging ball head 43 monitored by the second displacement sensor 14, so that the rotation radius of the nozzle 39 matches the container diameter; at the same time, the PLC controller 15 adjusts the height of the lifting frame 31 through the lifting electric cylinder 11, which is beneficial to ensuring that the converging ball head 43 always contacts the inner wall of the container;

[0042] The rotation motor 51 is used to drive the small gear 52 to rotate, and the meshing transmission cooperation of the small gear 52 and the external tooth ring 53 is used to drive the rotation frame 35 to rotate, thereby driving the two nozzles 39 to rotate synchronously, so that the two nozzles 39 swing backward and obliquely while rotating due to centrifugal force, thereby making the two converging ball heads 43 gradually approach and finally contact the inner wall of the container, so that the solution injection range of the two nozzles 39 can automatically adapt to the diameter of the container, and there is no need to replace the nozzle 39 when filling electronic chemicals into containers of different diameters, improving the versatility of the filling and injection of electronic chemical solutions;

[0043] The transfer pump 32 pumps the electronic chemical solution in the PVDF transfer pipeline 2 through the pump pipe 6, and pumps it out through the liquid inlet pipe 36 into the tee shunt cavity 37. The pumped solution will pass through the metal corrugated hose 38 and the spray head 39 in sequence and finally be sprayed out through the spray head 39. Since the metal corrugated hose 38 will produce a certain degree of bending, and at the same time the confluence ball head 43 has contacted the inner wall of the container, the spray head 39 is in an inclined state relative to the container at this time. Thus, the spray head 39 can inject the electronic chemical solution obliquely towards the inner wall of the container to avoid the electronic chemical solution from entraining air due to vertical impact on the bottom or liquid surface of the container. At the same time, since the spray head 39 is in a rotating state during injection, the solution can be injected into the container in a spiral rotation, using the centrifugal force to throw the bubbles in the solution towards the inner wall of the container, and at the same time reducing the liquid surface disturbance, effectively avoiding the appearance of bubbles when the electronic chemical solution is filled into the container, and will not cause shear stress to the electronic chemical solution, ensuring the performance of the electronic chemical product.

[0044] Two air suction components 7 are fixedly connected to the bottom end of the rotating frame 35. The air suction component 7 includes a suction cylinder 71 fixedly connected to the bottom end of the rotating frame 35. Air inlet holes 72 and exhaust holes 73 are formed in the side wall of the suction cylinder 71. A reciprocating piston 74 is hermetically slidably connected to the inner wall of the suction cylinder 71. A rectangular sleeve 75 is fixedly connected to the outer wall of the tee shunt cavity 37. An air inlet pipe 76 is fixedly communicated with the side wall of the rectangular sleeve 75. The air inlet pipe 76 is communicated with the suction cylinder 71 through the air inlet hole 72. An exhaust pipe 77 is fixedly communicated at the exhaust hole 73. An annular corrugated plate 78 is fixedly connected to the inner side of the lifting frame 31. A resisting rod 79 is fixedly connected to the outer wall of the reciprocating piston 74. The end of the resisting rod 79 penetrates through the axial side wall of the suction cylinder 71 and is fixedly connected with a resisting roller 710. The resisting roller 710 is in rolling contact with the annular corrugated plate 78. An alloy tension spring 711 is sleeved on the outer peripheral wall of the resisting rod 79. Both ends of the alloy tension spring 711 are fixedly connected with the reciprocating piston 74 and the inner wall of the suction cylinder 71 respectively;

[0045] Specifically, the waveform of the annular corrugated plate 78 is a sine wave, and the distance between adjacent wave peaks is 1 / 3 of the rotation radius of the rotating frame 35. The elastic coefficient of the alloy tension spring 711 is 15 N / mm, which can fully pull the reciprocating piston 74 to ensure the continuity and stability of the reciprocating and hermetic sliding of the reciprocating piston 74 in the suction cylinder 71;

[0046] Specifically, micro check valves are fixedly installed at both the air inlet hole 72 and the exhaust hole 73. The micro check valve at the air inlet hole 72 only allows air to enter the suction cylinder 71 from the air inlet pipe 76, and the micro check valve at the exhaust hole 73 only allows air to be discharged to the outside through the exhaust pipe 77 from the suction cylinder 71;

[0047] When the rotating frame 35 rotates, it can drive the suction cylinder 71 and the abutting roller 710 to rotate synchronously, so that the abutting roller 710 can be in rolling contact with the annular corrugated plate 78. During this process, when the abutting roller 710 is in rolling contact with the concave position of the annular corrugated plate 78, the alloy tension spring 711 will pull the reciprocating piston 74 through its own elastic force, reducing the pressure inside the suction cylinder 71 and causing the suction cylinder 71 to draw the air in the container into its interior through the intake pipe 76 and the rectangular sleeve 75. When the abutting roller 710 continues to rotate and is in rolling contact with the convex position of the annular corrugated plate 78, the abutting rod 79 will retract relative to the suction cylinder 71 and push the reciprocating piston 74, increasing the pressure inside the suction cylinder 71 and causing the air inside the suction cylinder 71 to be discharged to the outside through the exhaust pipe 77. Thus, the reciprocating piston 74 can perform reciprocating sealed sliding inside the suction cylinder 71, and the suction cylinder 71 can perform linked suction of the air in the container, so as to perform double real-time defoaming on the solution filled in the container, effectively improving the defoaming efficiency of the solution, being beneficial to ensuring the purity of the electronic chemical solution and the accuracy of the filling amount, and avoiding defects in the electronic chemicals in subsequent processes.

[0048] After the liquid injection is completed, the PLC controller 15 will automatically control the delivery pump 32 to stop, control the rotating motor 51 to decelerate, control the lifting electric cylinder 11 to drive the lifting frame 31 to rise and reset, and at the same time control the electric conveyor belt 8 to resume operation, so as to perform the next filling on the subsequent containers.

[0049] Experimental tests show that by adopting the double defoaming mechanism of the present invention, the bubble content in the solution after filling is reduced from 5% - 8% of the traditional method to less than 0.5%, and the defoaming time is shortened to within 3 seconds.

[0050] The working principle of the present invention is as follows:

[0051] In use, the electric conveyor belt 8 in the pipeline conveyor 1 is used to convey the container. The lateral guardrail 9 can protect and limit the container. When the first displacement sensor 13 detects that the container is directly below the delivery pump 32, the first displacement sensor 13 will send a signal to the PLC controller 15, causing the PLC controller 15 to start sending a stop signal to the electric conveyor belt 8 and simultaneously sending a start signal to the corresponding two lifting electric cylinders 11, so that the electric conveyor belt 8 stops conveying the container. At the same time, the two lifting electric cylinders 11 drive the lifting frame 31 to move downward, causing the two nozzles 39 and the two rectangular sleeves 75 to descend to the position of the container opening. At this time, the control rotation motor 51 is started, and the rotation motor 51 is used to drive the small gear 52 to rotate. The meshing transmission between the small gear 52 and the external gear ring 53 is used to drive the rotation frame 35 to rotate, thereby driving the two nozzles 39 to rotate synchronously, causing the two nozzles 39 to swing obliquely backward while rotating due to centrifugal force, so that the two converging ball heads 43 gradually approach and finally contact the inner wall of the container, enabling the solution injection range of the two nozzles 39 to automatically adapt to the diameter of the container;

[0052] When the second displacement sensor 14 detects that the two converging ball heads 43 contact the inner wall of the container, the second displacement sensor 14 starts to send a signal to the PLC controller 15, causing the PLC controller 15 to send a start signal to the corresponding delivery pump 32, so that the delivery pump 32 starts to pump the electronic chemical solution in the PVDF delivery pipeline 2 through the pump pipe 6 and pumps it out through the liquid inlet pipe 36 into the three-way shunt cavity 37. The pumped solution will pass through the metal corrugated hose 38 and the nozzles 39 in sequence and finally be sprayed out through the nozzles 39. Since the metal corrugated hose 38 will bend to a certain extent and the converging ball heads 43 have contacted the inner wall of the container, the nozzles 39 are in an inclined state relative to the container at this time, so that the nozzles 39 can inject the electronic chemical solution obliquely into the inner wall of the container. At the same time, since the nozzles 39 are in a rotating state during injection, the solution can be injected into the container in a spiral rotation, using centrifugal force to throw the bubbles in the solution to the inner wall of the container and reducing the liquid level disturbance at the same time;

[0053] During the rotation of the rotating frame 35, the suction cylinder 71 and the abutting roller 710 can rotate synchronously, so that the abutting roller 710 can be in rolling contact with the annular corrugated plate 78. During this process, when the abutting roller 710 is in rolling contact with the concave position on the annular corrugated plate 78, the alloy tension spring 711 will pull the reciprocating piston 74 through its own elastic force, reducing the pressure inside the suction cylinder 71 and causing the suction cylinder 71 to draw the air in the container into its interior through the intake pipe 76 and the rectangular sleeve 75. When the abutting roller 710 continues to rotate and is in rolling contact with the convex position on the annular corrugated plate 78, the abutting rod 79 will retract relative to the suction cylinder 71 and push the reciprocating piston 74, increasing the pressure inside the suction cylinder 71 and causing the air inside the suction cylinder 71 to be discharged to the outside through the exhaust pipe 77. Thus, the reciprocating piston 74 can complete reciprocating sealed sliding inside the suction cylinder 71, realizing the linkage suction of the air in the container by the suction cylinder 71.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
