Description

Technical Field

[0001] The present invention relates to the technical field of chemical packaging, and in particular to packaging equipment for an electronic chemical delivery system. Background Art

[0002] Electronic chemicals refer to high-purity chemical materials used in the field of electronics industry. They are usually used in the manufacture of electronic components such as semiconductors and integrated circuits. They have the characteristics of high purity and stable performance. They are key basic materials in the electronics industry. Reagent electronic chemicals include various strong solvents, strong acid and alkali solutions, and strong oxidants. When transporting and packaging them, materials that can resist the above reagents or solutions, such as fluoroplastics, need to be used; In the process of conveying electronic chemical solutions and injecting them into containers, turbulence is easily generated when the packaged solution quickly passes through narrow channels such as nozzles, causing the solution to mix with air, forming bubbles and eventually entering the container. In addition, under the high-speed injection method of center direct injection, the solution will vertically impact the bottom or liquid surface of the container, which may form a vortex on the liquid surface in the container and draw air into the liquid, which will also cause bubbles to form in the electronic chemical solution after packaging in the container. The bubbles will not only affect the accuracy of the packaging amount of the electronic chemical solution, but may also cause defects such as coating bubbles and uneven curing of electronic chemicals in subsequent processes. At present, static defoaming or mechanical stirring defoaming methods are often used, but the static defoaming method is too inefficient, and the mechanical stirring defoaming method is easy to cause shear stress to the electronic chemical solution, affecting the performance of the electronic chemical.

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The present invention will be further described below in conjunction with the embodiments.

[0018] Example: Refer to Figures 1 to 8 , a packaging device for an electronic chemical delivery system, comprising: an assembly line conveyor 1 and a PVDF delivery pipeline 2, an electric conveyor belt 8 is fixedly installed on the inner side of the assembly line conveyor 1, a lateral protection fence 9 is fixedly connected to the upper end surface of the assembly line conveyor 1, and two opposite outer walls of the assembly line conveyor 1 are slidably provided with a plurality of adaptive side injection components 3; the adaptive side injection component 3 comprises a lifting frame 31 slidably connected to the two opposite outer walls of the assembly line conveyor 1, a delivery pump 32 is fixedly installed on the upper end of the lifting frame 31, the delivery pump 32 adopts a plunger pump, an annular bearing 33 is fixedly connected to the lower end of the delivery pump 32, the outer ring of the annular bearing 33 is fixedly connected to a connecting bracket 34, the outer ring of the annular bearing 33 is rotatably 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 delivery pump 32, a plurality of connecting brackets 34 are fixedly connected to the lower ends of the rotating frames 35, a liquid inlet pipe 36 is fixedly connected to the middle of the rotating frame 35, and the inlet end of the liquid inlet pipe 36 is sealed and rotatably connected to the outlet end of the delivery pump 32; Specifically, the outlet end of the delivery pump 32 is rotatably connected to the inlet end of the liquid inlet pipe 36 through a sealed bearing, so that when the rotating frame 35 and the liquid inlet pipe 36 rotate relative to the delivery pump 32, the delivery pump 32 can be supported to pump the electronic chemical solution into the liquid inlet pipe 36; The outlet end of the liquid inlet pipe 36 is fixedly connected to a three-way diversion cavity 37, and the bottom end of the three-way diversion cavity 37 is fixedly connected to two metal corrugated hoses 38. The outlet ends of the two metal corrugated hoses 38 are fixedly connected to nozzles 39, and the outer walls of the two nozzles 39 are fixedly connected to counterweight blocks 310; Specifically, the metal corrugated hose 38 is made of stainless steel lined with polytetrafluoroethylene plastic. The metal corrugated hose 38 supports expansion and contraction and bending. When the rotating frame 35 rotates to drive the two nozzles 39 to rotate and causes the two nozzles 39 to tilt and swing in opposite directions due to centrifugal force, the metal corrugated hose 38 will shrink and bend to a certain extent to support the tilting and swinging of the nozzles 39 due to the centrifugal force. The counterweight block 310 is fixed to the outer wall of the nozzle 39. When the nozzle 39 rotates and tilts, the counterweight block 310 can increase the overall mass of the nozzle 39, thereby increasing the centrifugal force of the nozzle 39 when performing circular motion, i.e., rotating, thereby accelerating the speed at which the nozzle 39 tilts and swings to the inner wall of the container, thereby improving work efficiency. When the rotating frame 35 does not rotate, the metal corrugated hose 38 can automatically return to a state perpendicular to the ground under the gravity of the counterweight block 310. The inner wall of the nozzle 39 is fixedly connected with a flow focusing component 4, which includes a balance bracket 41 fixedly connected to the inner wall of the nozzle 39, a guide rod 42 fixedly connected to the lower end surface of the balance bracket 41, and a flow focusing ball head 43 fixedly connected to the end of the guide rod 42 outside the nozzle 39, and the flow focusing ball head 43 is made of fluororubber; Specifically, the angle between the spherical surface of the flow-converging ball head 43 and the outlet of the nozzle 39 is 45°. When the electronic chemical solution is sprayed from the nozzle 39, the flow-converging ball head 43 can constrain the sprayed solution so that the sprayed solution can form a concentrated flow, thereby increasing the stability of the sprayed solution, thereby avoiding the phenomenon of bubbles generated by the solution due to the formation of turbulence; A rotary drive component 5 is fixedly connected to the top of the lifting frame 31. The rotary drive component 5 is used to drive the rotating frame 35 to rotate. The rotary drive component 5 includes a rotary motor 51 fixedly installed on the top of the lifting frame 31. A small gear 52 is fixedly connected to the output end of the rotary motor 51. An outer gear ring 53 is fixedly connected to the outer wall of the rotating frame 35. The outer gear ring 53 and the small gear 52 are meshed with each other. The circumferential side walls of the PVDF conveying pipeline 2 are fixedly connected with a plurality of pump pipes 6, and the plurality of pump pipes 6 are respectively connected with the liquid inlet ends of the plurality of conveying pumps 32. The two opposite outer walls of the assembly line conveyor 1 are fixedly connected with the limit slide rails 10, and the lower end of the lifting frame 31 is slidably matched with the limit slide rails 10. A lifting electric cylinder 11 is fixedly installed at the lower position of the outer wall of the assembly line conveyor 1, and a supporting 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 surface of the supporting top plate 12, and a No. 1 displacement sensor 13, a No. 2 displacement sensor 14 and a PLC controller 15 are fixedly installed on the inner side of the lifting frame 31; Specifically, the No. 1 displacement sensor 13 is used to monitor the displacement of the container on the electric conveyor belt 8, and the No. 2 displacement sensor 14 is used to monitor the displacement of the two flow-gathering ball heads 43. The No. 1 displacement sensor 13, the No. 2 displacement sensor 14, the PLC controller 15, the lifting cylinder 11, the electric conveyor belt 8, and the delivery pump 32 are electrically connected to the external power supply. The PLC controller 15 adjusts the rotation speed of the rotating motor 51 according to the displacement signal of the flow-gathering ball head 43 monitored by the No. 2 displacement sensor 14, so that the rotation radius of the nozzle 39 matches the diameter of the container; at the same time, the PLC controller 15 adjusts the height of the lifting frame 31 through the lifting cylinder 11, which is conducive to ensuring that the flow-gathering ball head 43 always contacts the inner wall of the container; The small gear 52 is driven to rotate by the rotating motor 51, and the rotating frame 35 is driven to rotate by the meshing transmission of the small gear 52 and the outer gear ring 53, thereby driving the two nozzles 39 to rotate synchronously, so that the two nozzles 39 are tilted and swung in opposite directions while rotating due to the centrifugal force, so that 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 caliber of the container, and there is no need to replace the nozzle 39 when dispensing electronic chemicals into containers of different calibers, thereby improving the versatility of dispensing and injecting electronic chemical solutions; The delivery pump 32 pumps the electronic chemical solution in the PVDF delivery pipe 2 through the pump pipe 6, and pumps it out to the three-way diversion cavity 37 through the liquid inlet pipe 36. The pumped solution will pass through the metal corrugated hose 38 and the nozzle 39 in turn and finally be sprayed out through the nozzle 39. Since the metal corrugated hose 38 will bend to a certain extent, and the focusing ball head 43 has contacted the inner wall of the container, the nozzle 39 is tilted relative to the container at this time, so that the nozzle 39 can inject the electronic chemical solution obliquely into the inner wall of the container to avoid the electronic chemical solution from being drawn into the air due to vertical impact on the bottom or liquid surface of the container. At the same time, since the nozzle 39 is in a rotating state during injection, the solution can be injected into the container in a spiral rotation, and the bubbles in the solution are thrown to the inner wall of the container by centrifugal force, and the liquid surface disturbance can be reduced at the same time, effectively avoiding the appearance of bubbles when the electronic chemical solution is divided into the container, and no shear stress is caused to the electronic chemical solution, thereby ensuring the performance of the electronic chemical.

[0019] The bottom of the rotating frame 35 is fixedly connected to two air suction components 7, and the air suction component 7 includes a suction cylinder 71 fixedly connected to the bottom of the rotating frame 35, and the side wall of the suction cylinder 71 is provided with an air inlet hole 72 and an exhaust hole 73. The inner wall of the suction cylinder 71 is sealed and slidably connected with a reciprocating piston 74, and the outer wall of the three-way diversion cavity 37 is fixedly connected with a rectangular sleeve 75, and the side wall of the rectangular sleeve 75 is fixedly connected with an air inlet pipe 76, and the air inlet pipe 76 is connected with the suction cylinder 71 through the air inlet hole 72, and the exhaust hole 73 is connected with the suction cylinder 71 through the air inlet hole 72. An exhaust pipe 77 is fixedly connected at 73, an annular corrugated plate 78 is fixedly connected to the inner side of the lifting frame 31, a push rod 79 is fixedly connected to the outer wall of the reciprocating piston 74, the end of the push rod 79 passes through the axial side wall of the suction cylinder 71 and is fixedly connected to an abutting roller 710, the abutting roller 710 is in contact and rolling cooperation with the annular corrugated plate 78, an alloy tension spring 711 is sleeved on the outer peripheral wall of the push rod 79, and the two ends of the alloy tension spring 711 are respectively fixedly connected to the reciprocating piston 74 and the inner wall of the suction cylinder 71; Specifically, the waveform of the annular corrugated plate 78 is a sine wave, the distance between adjacent wave peaks is 1 / 3 of the rotation radius of the rotating frame 35, and the elastic coefficient of the alloy tension spring 711 is 15N / mm, which can fully pull the reciprocating piston 74 to ensure the continuity and stability of the reciprocating sealing sliding of the reciprocating piston 74 in the suction cylinder 71; Specifically, a micro check valve is fixedly installed at the air inlet 72 and the air outlet 73. The micro check valve at the air inlet 72 only allows air to enter the suction cylinder 71 from the air inlet pipe 76, and the micro check valve at the air outlet 73 only allows air to be discharged from the suction cylinder 71 to the outside through the exhaust pipe 77. 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 contact and rolling cooperation with the annular corrugated plate 78. In this process, when the abutting roller 710 rolls in contact with the concave position on the annular corrugated plate 78, the alloy tension spring 711 pulls the reciprocating piston 74 through its own elastic force, so that the pressure in the suction cylinder 71 is reduced, and the suction cylinder 71 draws the air in the container into the interior through the air inlet pipe 76 and the rectangular sleeve 75. When the abutting roller 710 continues to rotate and contacts the convex position on the annular corrugated plate 78, the reciprocating piston 74 is pulled by the alloy tension spring 711. When the contact rolls, the push rod 79 will retract relative to the suction cylinder 71 and push the reciprocating piston 74, so that the pressure in the suction cylinder 71 increases, and the air in the suction cylinder 71 is discharged to the outside through the exhaust pipe 77, so that the reciprocating sealing sliding of the reciprocating piston 74 in the suction cylinder 71 can be completed, and the suction cylinder 71 can realize the linked suction of the air in the container, so as to perform double real-time defoaming of the solution dispensed into the container, effectively improving the defoaming efficiency of the solution, which is beneficial to ensure the purity of the electronic chemical solution and the accuracy of the dispensing amount, and avoiding defects in the electronic chemicals in subsequent processes.

[0020] After the injection is completed, the PLC controller 15 will automatically control the delivery pump 32 to stop, control the rotating motor 51 to slow down, control the lifting cylinder 11 to drive the lifting frame 31 to rise and reset, and control the electric conveyor belt 8 to resume operation so as to carry out the next packaging of the subsequent containers.

[0021] Experimental tests show that by adopting the double defoaming mechanism of the present invention, the bubble content in the solution after packaging is reduced from 5%-8% in the traditional method to below 0.5%, and the defoaming time is shortened to within 3 seconds.

[0022] The working principle of the present invention is as follows: When in use, the electric conveyor belt 8 in the assembly line conveyor 1 is used to transport the container, and the lateral guardrail 9 can protect and limit the container. When the No. 1 displacement sensor 13 detects that the container is directly below the conveying pump 32, the No. 1 displacement sensor 13 will send a signal to the PLC controller 15, so that the PLC controller 15 starts to send a stop signal to the electric conveyor belt 8, and simultaneously sends a start signal to the corresponding two lifting cylinders 11, so that the electric conveyor belt 8 stops transporting the container, and at the same time the two lifting cylinders 11 drive the lifting frame 3 1 moves downward, so that the two nozzles 39 and the two rectangular sleeves 75 descend to the position of the container mouth. At this time, the rotating motor 51 is controlled to start, and the small gear 52 is driven to rotate by the rotating motor 51, and the meshing transmission cooperation between the small gear 52 and the outer gear ring 53 is used to drive the rotating frame 35 to rotate, thereby driving the two nozzles 39 to rotate synchronously, so that the two nozzles 39 rotate and tilt and swing in reverse directions due to the 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; When the second displacement sensor 14 detects that the two converging ball heads 43 are in contact with the inner wall of the container, the second displacement sensor 14 starts to send a signal to the PLC controller 15, and causes 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 pipe 2 through the pump tube 6, and pumps it out to the three-way diversion cavity 37 through the liquid inlet pipe 36. The pumped solution will pass through the metal corrugated hose 38 and the nozzle 39 in turn and finally be sprayed out through the nozzle 39. Since the metal corrugated hose 38 will bend to a certain extent and the converging ball head 43 has contacted the inner wall of the container, the nozzle 39 is tilted relative to the container at this time, so that the nozzle 39 can obliquely inject the electronic chemical solution into the inner wall of the container. At the same time, since the nozzle 39 is in a rotating state during injection, the solution can be injected into the container in a spiral rotation, and the bubbles in the solution are thrown to the inner wall of the container by centrifugal force, and the liquid surface disturbance can be reduced at the same time; 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 cooperate with the contact rolling of the annular corrugated plate 78. During this process, when the abutting roller 710 contacts and rolls with the recessed position on the annular corrugated plate 78, the alloy tension spring 711 will pull the reciprocating piston 74 through its own elastic force, so that the pressure in the suction cylinder 71 is reduced, and the suction cylinder 71 draws the air in the container into the interior through the air inlet pipe 76 and the rectangular sleeve 75. When the abutting roller 710 continues to rotate and contacts and rolls with the protruding 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, so that the pressure in the suction cylinder 71 is increased, and the air in the suction cylinder 71 is discharged to the outside through the exhaust pipe 77, so that the reciprocating sealing sliding of the reciprocating piston 74 in the suction cylinder 71 can be completed, and the linkage suction of the air in the container by the suction cylinder 71 can be realized.
