Description

Technical Field

[0001] This invention relates to the field of chemical filling equipment technology, and in particular to an automatic electronic chemical filling cabinet. Background Technology

[0002] Electronic chemicals are essential materials for the semiconductor and precision electronics manufacturing industries. Most types are highly volatile, thus the industry places high demands on safety and precision in their filling operations. Currently, conventional electronic chemical filling cabinet equipment has a relatively simple bottle conveying and positioning structure, making it prone to bottle misalignment and jamming during transport, affecting the smoothness and accuracy of the filling process. Furthermore, the materials release harmful gases during filling, and existing equipment cannot effectively collect these gases, allowing them to easily diffuse outwards, posing safety hazards and failing to meet environmental protection standards for workshops.

[0003] Therefore, those skilled in the art have provided an electronic chemical automatic filling cabinet to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic electronic chemical filling cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic electronic chemical filling cabinet includes a cabinet body. The interior of the cabinet body is divided into a filling area and a gas treatment area by a partition. A conveyor belt is installed at the bottom of the cabinet body, which spans the filling area and the gas treatment area for conveying filling bottles. Inlet and outlet ports are respectively opened on the left and right sides of the cabinet body corresponding to the two ends of the conveyor belt. A guide port for the filling bottles to pass through is opened on the partition. Two filling stations are provided in the filling area behind the conveyor belt, and the top surface of the filling station is flush with the conveying surface of the conveyor belt. A pushing mechanism is installed in the filling area in front of the conveyor belt, which is used to push the filled bottles on the conveyor belt to the filling station. A return mechanism is also installed in the rear of the filling area, which is used to push the filled bottles back to the conveyor belt. Above each of the two filling stations, there is a filling gun and a lifting drive unit that drives the filling gun to move up and down. A gas collection hood is installed within the gas processing area and above the conveyor belt path.

[0006] In the above technical solution, the interior of the cabinet is divided into a filling area and a gas treatment area, achieving functional zoning and separation. Filling operations and waste gas collection operations are carried out separately, effectively preventing the spread of harmful gases. The conveyor belt spans the two areas, forming a through-type conveying channel with the inlet, outlet, and guide inlet, which can be connected to the front and rear production lines to achieve continuous production. The filling area integrates a pushing mechanism, a return mechanism, a filling gun, and a lifting drive unit, which can automatically complete the bottle transfer, lifting, and filling actions. The gas treatment area is equipped with a gas collection hood, which can centrally collect the volatile gases generated during filling. From a structural perspective, it simultaneously meets the three major requirements of automated filling, safety protection, and waste gas treatment.

[0007] Furthermore, side baffles are fixed inside the cabinet and on both the front and rear sides of the conveyor belt; conveyor rollers are rotatably mounted on the left and right ends of the two side baffles via bearing seats, and the conveyor belt is wound around the outside of the two sets of conveyor rollers; a conveyor drive motor is driven to the shaft end of one of the conveyor rollers; the top surface of the side baffle is higher than the conveying surface of the conveyor belt, and clearance notches are opened on the two side baffles corresponding to the working positions of the pushing mechanism and the return mechanism.

[0008] In the above technical solution, side baffles are set on both sides of the conveyor belt, which, together with the conveyor rollers at both ends and the conveyor drive motor, form a complete conveying mechanism. The side baffles can limit the left and right movement of the filling bottles during conveying to prevent the bottles from shifting or tipping over. The clearance openings on the side baffles reserve the operating space for the pushing mechanism and the return mechanism, ensuring that the various mechanical mechanisms do not interfere with each other. The overall structure of the equipment is compact, and the stability of the conveying operation is significantly improved.

[0009] Furthermore, the pushing mechanism includes a support frame fixed to the front side baffle; a pushing cylinder is horizontally fixed at the top center of the support frame, the output end of the pushing cylinder faces the conveyor belt and is fixedly connected to a push plate; a blocking cylinder is installed on both the left and right sides of the pushing cylinder on the support frame, a blocking block is fixed at the output shaft end of the blocking cylinder, and the end of the blocking block facing the conveyor belt is set as a guide slope.

[0010] In the above technical solution, the feeding mechanism adopts a combination of a support frame with a pushing cylinder and a blocking cylinder. The blocking block can pre-limit the filling bottles on the conveyor belt, and the guide slope has a guiding function to prevent the bottles from getting stuck. The pushing cylinder works with the push plate to complete the smooth feeding, which can accurately push the filling bottles to the filling station, ensuring the filling alignment accuracy. No manual intervention is required throughout the process, which improves the automation level of feeding.

[0011] Furthermore, the return mechanism includes a support frame fixed to the rear side of the filling area; a return cylinder is horizontally mounted on the top of the support frame, and a push seat is fixed to the end of the output shaft of the return cylinder; the front left and right sides of the push seat are provided with arc-shaped grooves that are adapted to the outer contour of the filling bottle.

[0012] In the above technical solution, the return mechanism consists of a support frame, a return cylinder, and a return pusher. The front end of the return pusher has an arc-shaped groove that matches the outer contour of the bottle. During the pushing process, it can form a wrapping positioning of the bottle, preventing the bottle from sliding or tilting. It can smoothly push the filled bottle back to the conveyor belt, ensuring the stability of the bottle transfer process.

[0013] Furthermore, limit blocks are fixed on the left, right and rear sides of the top of the filling station, and the end of the limit blocks on both sides facing the conveyor belt is set as a symmetrical outward-expanding guide slope; the filling station is mounted on the base, and a weighing unit is clamped between the base and the filling station; the bottom surface of the push seat is higher than the top surface of the limit block.

[0014] In the above technical solution, three limit blocks are set on the filling station in a U-shape to guide the bottle into the filling position and limit its movement, thereby improving the filling positioning accuracy. The weighing unit is integrated between the base and the filling station, which can directly support the filling bottle and collect weight data in real time. The bottom surface of the push seat is higher than the top surface of the limit block to ensure that the return mechanism will not mechanically interfere with the limit block when it moves.

[0015] Furthermore, a first guide plate is fixed above the support frame; a second guide plate is fixed on top of the rear side baffle in the gas treatment area; the adjacent ends of the first guide plate and the second guide plate are connected to each other, and an arc-shaped guide slope is provided at the connection position.

[0016] In the above technical solution, the first guide plate and the second guide plate are connected to each other, and an arc-shaped guide slope is set at the connection point. This can guide the filling bottles transported across regions, avoid the bottles from bumping or getting stuck at the connection point, further optimize the smoothness of the transport, and extend the service life of the equipment and the bottles.

[0017] Furthermore, mounting plates are vertically fixed on the left and right sides inside the gas treatment area, and mounting plates are evenly arranged with assembly holes along the vertical direction; both ends of the gas collection hood are fixedly connected to the mounting plates on both sides by fasteners; the top of the gas collection hood is connected to a gas guide pipe, which extends upward to the outside of the cabinet and is connected to external waste gas treatment equipment. A fixed base is fixed behind the rear side baffle in the gas processing area. A stop arm is rotatably mounted on the front side of the top of the fixed base, and a telescopic cylinder is rotatably mounted on the rear side of the top of the fixed base. The output end of the telescopic cylinder is hinged to the middle of the stop arm. A passage hole is provided on the side baffle for the stop arm to rotate freely.

[0018] In the above technical solution, the mounting plate has uniformly spaced assembly holes, which can flexibly adjust the installation height of the gas collection hood according to the actual working conditions, and at the same time facilitate the disassembly, inspection and maintenance of the gas collection hood; the gas collection hood, together with the gas guide pipe, transports the collected volatile gases to the external waste gas treatment equipment for harmless treatment; the telescopic cylinder drives the baffle arm to rotate, which can temporarily block the bottle in the transport, extend the gas collection time, and greatly improve the waste gas collection efficiency; the passage holes on the side baffle ensure that the rotation of the baffle arm is not obstructed, and the structure is reasonably designed.

[0019] Furthermore, the front left and right sides of the cabinet are respectively equipped with sealed cabinet doors corresponding to the filling area and the gas processing area, and the sealed cabinet doors are equipped with viewing windows; a fan filter unit is installed on the top of the cabinet.

[0020] In the above technical solution, the sealed cabinet door achieves overall airtightness of the cabinet, while facilitating subsequent opening for equipment debugging; the viewing window on the cabinet door allows real-time observation of the internal filling and conveying status without opening the cabinet door, facilitating equipment inspection; the fan filter unit installed on the top of the cabinet can circulate and purify the air inside the cabinet, meeting the dust-free and clean operating environment requirements for electronic chemical filling.

[0021] Furthermore, the filling cabinet also includes a weighing and metering module, which comprises a weighing acquisition unit, a signal transmission unit, and a filling linkage unit. The weighing acquisition unit is electrically connected to the weighing unit and collects the weight data of the filling bottle and the internal electronic chemicals in real time, and uploads the data to the filling linkage unit via the signal transmission unit. The filling linkage unit has a built-in data parsing subunit and a multi-channel control output subunit, which are used to interface with the opening and closing control circuit of the filling gun and the drive circuit of the lifting drive unit. When the parsed weight data reaches the preset filling threshold, the filling linkage unit issues control commands in sequence, first controlling the filling gun to cut off the liquid dispensing, and then controlling the lifting drive unit to drive the filling gun to complete the lifting and resetting action.

[0022] In the above technical solution, a closed-loop control system of weighing acquisition, signal transmission and linkage control is constructed. The weighing acquisition unit collects weight data in real time and uploads it to the filling linkage unit. After data analysis, the filling volume is accurately determined. When the preset threshold is reached, the command is issued in the sequence of "stop liquid first and then reset". This ensures the accuracy of filling measurement and avoids material waste and pollution caused by residual material dripping from the filling gun, thus realizing the automated and precise control of quantitative filling.

[0023] Furthermore, the filling cabinet also includes a position sensing and automatic control module; the position sensing and automatic control module includes multiple sets of position sensors, a main controller and a drive control loop. The multiple sets of position sensors are respectively arranged at the feed inlet, filling station, guide inlet and discharge outlet to detect the real-time position of the filled bottles; the main controller, based on the sensor signals, coordinates the start and stop of the conveyor belt, pushing mechanism, return mechanism, baffle arm and gas collection hood and matching exhaust equipment to realize the automated continuous filling operation of the whole machine.

[0024] In the above technical solution, multiple sets of position sensors are arranged at key points of the equipment to monitor the position information of the filling bottles in real time and feed it back to the main controller. The main controller coordinates the start and stop of all components such as the conveyor belt, the pushing mechanism, the return mechanism, the baffle arm, and the exhaust equipment according to the position signal, so as to realize the linkage operation of the whole machine in the whole process, completely eliminate manual operation, greatly improve the efficiency of the assembly line operation, and the equipment has a high degree of automation integration.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. This equipment optimizes the bottle conveying and positioning structure, which can effectively avoid bottle shifting and jamming during the transfer process, ensuring smooth conveying, improving filling alignment accuracy, and stabilizing operation quality.

[0026] 2. The equipment is equipped with a complete gas collection and material interception structure, which can fully collect harmful volatile gases generated during filling and effectively prevent the gas from spreading outward, thus eliminating on-site safety hazards and meeting the environmental protection production standards of the workshop.

[0027] 3. The whole machine relies on the linkage between the mechanical structure and the electrical control module to realize the automation of processes such as feeding, filling and transfer, reduce manual operation and effectively improve the overall production efficiency.

[0028] 4. The equipment uses a weighing and metering mode to complete quantitative filling, with precise control of the filling volume. Combined with a sealed cabinet and a fan filter unit, it can create a clean working environment and is suitable for the filling and use requirements of electronic chemicals.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1, see attached document Figure 1-4 : An automated electronic chemical filling cabinet includes a cabinet body 1. A vertical partition 2 is installed inside the cabinet body 1, dividing the interior into two independent functional areas: a filling area and a gas handling area. A conveyor belt 3 is horizontally mounted at the bottom of the cabinet body 1, passing through the partition 2 and spanning both the filling and gas handling areas, serving as the transport carrier for the filled bottles 4. Inlet 5 and outlet 6 are respectively located on the left and right sides of the cabinet body 1, and a guide port 7 is located in the middle of the partition 2. The filled bottles 4 can be transported across areas sequentially via the inlet 5, conveyor belt 3, and guide port 7. The overall structure can be directly connected to upstream and downstream production lines, adapting to continuous operation scenarios.

[0034] Two filling stations 8 are set up behind the conveyor belt 3 in the filling area. The top surface of the filling station 8 is flush with the conveying surface of the conveyor belt 3 to ensure that there is no height difference during the bottle transfer process. Each filling station 8 is equipped with a filling gun 9 and a lifting drive unit 10. The lifting drive unit uses a lifting cylinder as the power component, which can drive the filling gun holder to make a linear reciprocating motion up and down. The filling gun 9 is fixedly installed on the filling gun holder and is connected to the material conveying main pipeline through an external pipeline to realize the conveying and filling operation of electronic chemicals. In the gas treatment area, a gas collection hood 11 is set up above the conveying path of the conveyor belt 3 to collect harmful gases volatilized during the filling process.

[0035] This solution adopts a physical partition layout to isolate the filling operation from the exhaust gas collection operation, reducing the spread of harmful gases from the source. The filling components can automatically complete the lifting and positioning and material filling actions, and work with the gas collection hood to achieve centralized collection of exhaust gas. One set of equipment meets multiple usage requirements such as automated filling, safety protection and exhaust gas treatment, and is suitable for the special filling conditions of electronic chemicals.

[0036] Example 2, see attached document Figure 4 : Inside the cabinet 1, side baffles 12 are symmetrically fixed on the front and rear sides of the conveyor belt 3. The left and right ends of the two side baffles 12 are equipped with conveyor rollers 13 through bearing seats. The conveyor belt 3 is wrapped around the outside of the two sets of conveyor rollers 13 in a ring. The shaft end of one of the conveyor rollers 13 is connected to the conveyor drive motor. The conveyor drive motor provides power to drive the conveyor roller 13 and the conveyor belt 3 to rotate in a cycle.

[0037] The top surface of the side baffle 12 is higher than the conveying surface of the conveyor belt 3, which can limit the left and right movement of the filling bottle 4 during operation, effectively preventing the bottle from shifting or tipping over during the conveying process. The two side baffles 12 also have clearance openings corresponding to the working areas of the pushing mechanism and the return mechanism, reserving space for moving parts such as cylinders and push plates. The entire conveying transmission structure operates stably, the side baffles serve both limiting and protective functions, and the clearance openings optimize the internal space layout of the equipment, ensuring that the operation of each mechanical mechanism does not interfere with each other, reducing the equipment failure rate.

[0038] Example 3, see attached document Figure 3-4 : The material pushing mechanism is mounted on the front side baffle 12, with the support frame 14 as the overall mounting base. A pushing cylinder 15 is horizontally fixed at the top center of the support frame 14. The output end of the pushing cylinder 15 faces the conveyor belt 3, and the end is fixed to the push plate 16. On the left and right sides of the pushing cylinder 15, two sets of blocking cylinders 17 are symmetrically arranged horizontally. A blocking block 18 is fixed at the end of the output shaft of each set of blocking cylinders 17. The end of the blocking block 18 facing the conveyor belt 3 is machined with a guide slope.

[0039] During operation, the conveyor belt 3 drives the filling bottles 4 continuously along the conveyor path. When a filling bottle approaches the working area, the left-side baffle cylinder 17 extends towards the conveyor belt first, using the left-side baffle block 18 to block the bottle from continuing forward. After the first filling bottle enters the working area between the two sets of baffle blocks, it is briefly released to allow the second filling bottle to enter the same area. Once both filling bottles are in place, the right-side baffle cylinder 17 extends outward simultaneously, and the two sets of baffle blocks 18 cooperate to limit the two filling bottles between the two baffle blocks, preventing the bottles from shifting or deviating.

[0040] After the dual-bottle positioning is completed, the pusher cylinder 15 extends forward, and the pusher plate 16 smoothly pushes the two bottles to the corresponding two filling stations 8. The guide slope set on the baffle block 18 can guide the filling bottles, effectively preventing the bottles from contacting the baffle block and preventing jamming and collision during the pushing process. This pushing mechanism can achieve synchronous positioning and feeding of dual bottles, with smooth and continuous operation, precise matching with the dual filling stations, and high pushing alignment accuracy.

[0041] The return mechanism is located at the rear of the filling area and consists of a support frame 19, a return cylinder 20, and a pusher seat 21. The return cylinder 20 is horizontally mounted on the top of the support frame 19, and its output shaft is fixed to the pusher seat 21. The pusher seat 21 has arc-shaped grooves on its front left and right sides, the contour of which matches the outer wall of the filled bottle 4. After filling is completed, the return cylinder 20 pushes the pusher seat 21 forward, and the arc-shaped grooves conform to the bottle body to form a wrapping limit, smoothly pushing the filled bottle back to the conveyor belt 3. During the transfer, the bottle will not slip or tilt. The pushing mechanism and the return mechanism work together to achieve automated bidirectional transfer of the filled bottle 4 between the conveyor belt 3 and the filling station 8.

[0042] Example 4, see attached document Figure 6 : Each filling station 8 has fixed limit blocks 22 on its top left, right, and rear sides. The end of the limit blocks 22 facing the conveyor belt 3 is set as a symmetrically flared guide slope, forming a trumpet-shaped guide structure. When the filling bottle 4 is pushed to the filling station 8 by the pushing mechanism, the bottle can quickly enter between the two limit blocks 22 along the guide slope until it abuts the rear limit block 22. The rear limit block 22 also has a groove that matches the outer contour of the bottle, which facilitates guiding the bottle to the bottom of the filling gun 9, thereby ensuring that the filling gun 9 is accurately aligned with the bottle mouth.

[0043] The filling station 8 is mounted on top of the base 23. A weighing unit 24 is clamped between the base 23 and the filling station 8. The weighing unit 24 can directly bear the total weight of the filling station 8, the filling bottle 4, and the electronic chemicals inside the bottle, and collect weight data in real time to provide data support for quantitative filling. At the same time, the bottom surface of the push seat 21 is set to be higher than the top surface of the limit block 22. When the return mechanism performs the pushing action, the push seat 21 will not collide or jam with the limit block 22. The various structures are closely matched and have high operational reliability.

[0044] Example 5, see attached document Figure 5 : A first guide plate 25 is fixed above the support frame 14, and a second guide plate 26 is fixed on top of the rear side baffle 12 in the gas treatment area. The adjacent ends of the first guide plate 25 and the second guide plate 26 overlap and connect with each other, and an arc-shaped guide slope is machined at the connection point. When the filling bottle 4 is conveyed from the filling area to the gas treatment area, it will pass through the connection point of the two guide plates. The arc-shaped guide slope can buffer the impact force generated by the movement of the bottle, avoid problems such as the bottle bumping, bouncing, and jamming, greatly improve the smoothness of the filling bottle 4 across areas, and at the same time, it can also protect the bottle and equipment parts, and extend the service life of the equipment and container.

[0045] Example 6, see attached document Figure 1-4 : Mounting plates 27 are vertically fixed on both sides of the gas treatment area. Mounting plates 27 have evenly spaced mounting holes along the vertical direction. The gas collection hood 11 is detachably mounted on the mounting plates 27 at both ends using fasteners. Operators can flexibly adjust the installation height of the gas collection hood 11 according to the bottle specifications and material volatile concentration, making disassembly, assembly, and maintenance convenient. The top of the gas collection hood 11 is connected to a gas guide pipe 28, which extends upwards to the outside of the cabinet 1 and connects to external waste gas treatment equipment. This allows the collected volatile gases to be uniformly transported to specialized equipment for harmless treatment.

[0046] The gas treatment area is also equipped with a material blocking assembly. A fixed base 29 is fixed behind the side baffle 12. A baffle arm 30 and a telescopic cylinder 31 are rotatably mounted on the top of the fixed base 29. The output end of the telescopic cylinder 31 is hinged to the middle of the baffle arm 30. A passage hole is provided on the side baffle 12 for the baffle arm 30 to move. When the telescopic cylinder 31 performs the telescopic action, it can drive the baffle arm 30 to swing around the hinge point. When the baffle arm 30 rotates above the conveyor belt 3, it can temporarily block the filling bottle 4 from moving forward, prolonging the time the bottle stays under the gas collection hood 11, effectively improving the waste gas collection efficiency. The passage hole can ensure that the baffle arm 30 swings without obstruction throughout its entire movement.

[0047] Sealed cabinet doors 32 are installed at the front of cabinet 1, corresponding to the filling area and gas handling area. Each sealed cabinet door 32 has a viewing window. When closed, the cabinet 1 forms a sealed space, further preventing the leakage of harmful gases. Operators can directly observe the internal conveying and filling operations through the viewing windows, completing daily inspections without opening the cabinet doors. A fan filter unit 33 is installed at the top of cabinet 1, capable of circulating, filtering, and purifying the air inside the cabinet, meeting the dust-free and clean operating environment requirements for electronic chemical filling.

[0048] This equipment is also equipped with two sets of electrical control modules: a weighing and metering module and a position sensing and automatic control module. The weighing and metering module includes a weighing acquisition unit, a signal transmission unit, and a filling linkage unit. The filling linkage unit has a built-in data analysis subunit and a multi-channel control output subunit. The weighing acquisition unit is electrically connected to the weighing unit 24, and collects weight data in real time. It is then uploaded to the filling linkage unit through the signal transmission unit. The data analysis subunit compares the real-time weight with the system's preset filling threshold. When the set value is reached, the multi-channel control output subunit sends commands to the opening and closing control circuit of the filling gun 9 and the drive circuit of the lifting drive unit 10 in sequence. First, it controls the filling gun 9 to cut off the liquid dispensing, and then it controls the lifting cylinder to drive the filling gun seat and the filling gun 9 to reset. The entire closed-loop control system not only ensures the accuracy of filling and metering, but also avoids the dripping of residual material from the filling gun, reducing material waste and cabinet contamination.

[0049] The position sensing and automatic control module consists of multiple position sensors, a main controller, and a drive control loop. The position sensors are positioned at key locations such as the feed inlet 5, filling station 8, guide inlet 7, and discharge outlet 6 to monitor the position and operating status of the filling bottles 4 in real time and feed the signals back to the main controller. Based on the sensor signals, the main controller coordinates the start and stop of the conveyor belt 3, pushing mechanism, return mechanism, baffle arm 30, and the waste gas collection hood 11, achieving fully automated operation of the entire process from feeding, pushing, filling, transfer, waste gas collection, to discharge. This eliminates the need for manual operation, significantly improving production line efficiency and equipment automation integration.
