Description

Technical Field

[0001] The present application relates to the field of automated testing equipment, and in particular to an automated testing system for chemical liquids used in PBC board processing. Background Art

[0002] In the processing of PBC boards, the quality control of chemical liquids is crucial. In order to ensure product quality, it is usually necessary to conduct regular tests on various chemical liquids such as acid copper chloride solution and alkaline copper chloride solution. This process is not only related to the stable operation of the production process, but also directly affects the product qualification rate and the economic benefits of the enterprise. With the development of industrial automation, improving test efficiency and reducing manual intervention have become the development trend of the industry.

[0003] At present, the commonly used testing methods in the chemical industry mainly include manual sampling and laboratory analysis. Specifically, workers will extract several samples at regular intervals in each process and send these samples to the laboratory one by one for detailed chemical composition analysis. In addition, some companies will also use semi-automatic equipment to assist manual operations, such as using a simple conveyor belt to send samples to a fixed testing point, but the final inspection work is still required manually. Although these methods meet basic testing needs to a certain extent, they seem to be inadequate when facing large-scale production lines.

[0004] However, the above traditional manual testing methods have many shortcomings. First, the workload of manual sampling and testing is large and time-consuming, which easily leads to delayed test results and cannot reflect changes in the production process in a timely manner. Secondly, the errors in manual operation are large, and it is difficult to ensure the consistency and accuracy of each test. Especially when multiple production lines are operated in parallel, the difficulty of manual management is further increased, the work efficiency is low, and human errors are prone to occur. Therefore, there is an urgent need for a more efficient and accurate automated testing system to replace the existing manual operation mode. Summary of the invention

[0005] In order to improve the consistency and accuracy of the test, as well as to improve the test efficiency, the present application provides a chemical liquid automatic test system for PBC board processing.

The design of the feed position, discharge position and temporary storage position allows the tray to be quickly switched between different workstations, reducing waiting time, reasonably dividing the different functional areas of the loading platform, and making full use of the limited space resources of the loading platform, making the entire system more compact and efficient, and conducive to improving the transfer efficiency of trays.

Through the design of the slide and the lifting drive, the height position of each dripper can be accurately controlled, so as to ensure that the best position can be reached every time the reagent is added, reducing the error caused by the different heights of the drippers; the vertical sliding design of the slide allows multiple liquid supply components to flexibly adjust the position of the dripper according to actual needs, adapt to different types of test requirements, and improve the scope of application of the equipment; the automated lifting drive replaces the manual adjustment of the dripper height operation, reduces manual intervention, reduces the difficulty of operation, and improves work efficiency; when the stirring mechanism needs to be cleaned, the dripper can be moved to the appropriate position through the lifting drive, which is convenient for the injection of clean water and the thorough cleaning of the stirring mechanism to avoid cross contamination.

[0015] By adopting the above technical solution, the beaker to be cleaned containing waste liquid is sent from the transfer table to the draining area by the material transfer mechanism and turned upside down in the drain tank, which effectively removes most of the residual liquid and reduces the burden of subsequent cleaning. Subsequently, the transfer mechanism transfers the beaker to the rinsing area and the drying area successively, and thoroughly cleans and quickly dries the inner and outer walls respectively. Each work area is responsible for a specific cleaning step to ensure that each step can be performed efficiently and reliably. Finally, the cleaned beaker is moved to the waiting area for further processing, so that the transfer mechanism can move the beaker in the waiting area to the discharge position of the automatic loading and unloading device. The entire process is highly automated, which greatly reduces the workload of the staff and improves the efficiency of the test and the consistency of the cleaning quality.

[0016] Preferably, the flushing mechanism comprises: A rinsing tank, wherein a first nozzle is arranged on the bottom wall of the rinsing tank, and a beaker to be rinsed is placed upside down in the rinsing tank and covered above the first nozzle, and the spraying range of the first nozzle covers the inner wall of the beaker; A water shield, the water shield is used to cover the outer periphery of the beaker to be rinsed, a second nozzle is arranged inside the water shield, and the spray range of the second nozzle covers the outer wall of the beaker; A first driving member, the first driving member is used to drive the water shield to move up and down; A water supply component is connected to the first nozzle and the second nozzle, and is used to transport cleaning liquid to the first nozzle and the second nozzle.

[0020] Preferably, the transfer mechanism includes a horizontal frame and a plurality of first suction cups laterally distributed on the horizontal frame, and the workbench is provided with a third driving member for driving the horizontal frame to move vertically and laterally; when the transfer mechanism performs the beaker transfer step, under the drive of the third driving member, the plurality of first suction cups on the horizontal frame simultaneously adsorb the beakers in the draining area, the rinsing area and the drying area, and perform synchronous transverse movement under the drive of the third driving member, so as to transfer the beakers in the upper working area to the lower working area.

[0021] By adopting the above technical solution, the horizontal frame and the multiple first suction cups thereon can simultaneously absorb multiple beakers in different working areas (such as the draining area, the rinsing area, and the drying area), and perform synchronous vertical and horizontal movements under the action of the third driving member, thereby quickly and accurately transferring the beakers from one working area to another.

Specifically, the design of the moving seat and the moving drive member enables the entire material transfer mechanism to be freely raised and lowered in the vertical direction, thereby adapting to the needs of different heights. The flip seat and its first flip drive member can realize the rollover action in the horizontal plane, and cooperate with the downward movement of the moving seat to smoothly transfer the beaker to the specified position. The flip rack and its second flip drive member can complete the change of the beaker from the upright state to the inverted state, ensuring that the residual liquid inside the beaker is fully discharged before entering the draining area. The combined use of the grabbing assembly and the fourth drive member allows the manipulator to move flexibly in three-dimensional space, accurately capture the target beaker and transport it to the flip rack. The whole process has a high degree of automation, reduces manual operation, and improves work efficiency. Overall, the cleaning efficiency is improved, the possibility of manual intervention is reduced, and the safety and stability of the system operation are enhanced.

[0040] The following is combined with Figure 1-14 This application is described in further detail.

[0041] The present application embodiment discloses a chemical liquid automatic testing system for PBC board processing, referring to Figure 1 , including an automatic loading and unloading device 1, an automatic testing device 3, a transfer table 5, a first automatic cup transfer device 6, a second automatic cup transfer device 7, an automatic cleaning device 4 and a circulating feeding device 8 (such as Figure 3 as shown).

[0042] Reference Figure 1 and Figure 2 The automatic loading and unloading device 1 is provided with a feeding position 112 and a discharging position 111. The feeding position 112 can be placed with a beaker 9 to be tested. The beaker 9 to be tested refers to a beaker 9 containing a solution to be tested.

[0043] The automatic testing device 3 is used to drip the reaction solvent into the beaker 9 to be tested and perform the testing operation. After the testing operation is completed, the solution in the beaker 9 is treated as waste liquid.

[0044] The transfer table 5 is used to temporarily store beakers 9 to be tested and beakers 9 containing waste liquid. The first automatic cup transfer device 6 is used to transfer the beakers 9 to be tested at the feed position 112 to the transfer table 5. The second automatic cup transfer device 7 is used to transfer the beakers 9 to be tested on the transfer table 5 to the automatic test device 3, and to transfer the beakers 9 containing waste liquid in the automatic test device 3 to the transfer table 5.

[0045] The automatic cleaning device 4 is used to clean the beaker 9 containing waste liquid on the transfer table 5 , and to transfer the cleaned beaker 9 to the discharge position 111 of the automatic loading and unloading device 1 .

[0046] The circulating feeding device 8 is used to feed the beakers 9 at the discharge position 111 and to feed the beakers 9 to be tested into the feed position 112 .

[0047] The entire automated testing system forms a complete cycle process, and the entire process does not require human intervention, which greatly improves the testing efficiency and system reliability, and also reduces the errors and safety hazards caused by human operation. In this embodiment, the first automatic cup transfer device 6 and the second automatic cup transfer device 7 both use multi-joint manipulators to accurately grasp the beaker 9 across obstacles.

[0048] In this embodiment, in order to be able to perform more kinds of test operations, a static table 2 is added. The static table 2 can temporarily place the beaker 9 containing the solution reaction so as to perform static precipitation and other operations. In addition, the static table 2 is also provided with heating equipment and cooling equipment commonly used in chemical experiments so as to heat or cool the solution to be tested or the solution in reaction. The transfer of the beaker 9 between the static table 2 and the automatic test device 3 can be completed by the second automatic cup transfer device 7. In addition, the automatic test device 3 is provided with multiple groups so as to perform multiple groups of simultaneous test operations or a group of test operations performed sequentially.

[0049] In this embodiment, the automatic loading and unloading device 1, the stationary table 2, multiple groups of automatic testing devices 3, and the automatic cleaning device 4 are connected end to end to form a circular production line, wherein the length direction of the automatic loading and unloading device 1 is taken as the longitudinal direction, and the length direction of the automatic cleaning device 4 is taken as the transverse direction. The transfer table 5 is located in the middle of the circular production line, the first automatic cup transfer device 6 is arranged between the automatic loading and unloading device 1 and the transfer table 5, and the second automatic cup transfer device 7 is arranged between the automatic testing device 3 and the transfer table 5, so that the cycle process formed by the automatic testing system is more compact and can be carried out smoothly.

[0050] Reference Figures 2 to 5The automatic loading and unloading device 1 includes a loading platform 11 and a conversion mechanism. The loading platform 11 is longitudinally divided into a discharge position 111, a feed position 112 and a temporary storage position 113 for placing the tray 10, wherein the feed position 112 and the discharge position 111 are both connected to the rear of the loading platform 11 for the circulation feeding device 8 to enter. Specifically, the circulation feeding device 8 places the tray 10 holding the beaker 9 to be tested at the feed position 112, and the automatic cleaning device 4 places the cleaned beaker 9 at the tray 10 at the discharge position 111.

[0051] In this embodiment, the upper ends of the feed position 112 and the discharge position 111 both pass through the surface of the loading platform 11, and the longitudinal length of the tray 10 is greater than the longitudinal length of the feed position 112 and the discharge position 111 to meet the requirement that the tray 10 can be stably placed on the surface of the loading platform 11 at the feed position 112 and the discharge position 111.

[0052] In the present embodiment, the circulating feeding device 8 includes a mobile trolley and a bracket installed on the mobile trolley and capable of being raised and lowered, and the bracket is used to carry a pallet 10. The lifting function of the bracket can be realized by a cylinder system on the mobile trolley. In the present embodiment, the mobile trolley adopts an AGV, which can travel along a prescribed guide path. Two pallets 10 distributed side by side can be placed on the surface of the bracket. In addition, a positioning protrusion is provided on the surface of the bracket, and a positioning hole adapted to the positioning protrusion is provided at the bottom of the pallet 10. When the pallet 10 is placed on the surface of the bracket, the positioning hole and the positioning protrusion are plugged and matched to improve the stability of the pallet 10. In addition, both sides of the pallet 10 protrude from the bracket, so that the pallet 10 can be stably placed on the upper surface of the loading platform 11 on the basis of the circulating feeding device 8 smoothly entering the feeding position 112 or the discharging position 111. Specifically, when the circulating feeding device 8 enters the feeding position 112, the height position of the bearing surface of the bracket is higher than the surface of the loading platform 11. After the circulating feeding device 8 enters the feeding position 112, the circulating feeding device 8 places the tray 10 steadily on the surface of the loading platform 11 by lowering the bracket. When the circulating feeding device 8 enters the discharging position 111, the height position of the bearing surface of the bracket is lower than the surface of the loading platform 11. The circulating feeding device 8 pushes the tray 10 away from the surface of the loading platform 11 by raising the bracket, so as to achieve the purpose of loading and unloading the tray 10. The circulating feeding device 8 goes back and forth between the discharging position 111 and the feeding position 112, and the beaker 9 that has undergone a set of processes such as heating, standing, testing, and cleaning of the automatic testing system is sent to the feeding position 112 again, thereby achieving the purpose of recycling the beaker 9.

[0053] In order to further improve the smoothness and accuracy of the loading and unloading device of the beaker 9 tray 10, guide structures are installed at the feed position 112 and the discharge position 111. Taking the feed position 112 as an example, two limit wheel sets are installed in the feed position 112, and the limit wheel sets extend horizontally to the depth of the feed position 112. The two limit wheel sets are symmetrically distributed on both sides of the travel path of the mobile trolley. When the mobile trolley enters the feed position 112, the two limit wheel sets are respectively abutted against the two sides of the mobile trolley. The mobile trolley has rolling friction with the limit wheel sets during the movement, so that the mobile trolley enters the feed position 112 in a centered position. When the mobile trolley is in place at the feed position 112, the mobile trolley stops moving forward and starts the subsequent tray 10 placement step. The structure of the discharge position 111 is consistent with that of the feed position 112, which will not be repeated here.

[0054] In this embodiment, the conversion mechanism is used to transfer the tray 10 on the loading platform. When the beakers 9 to be tested on the tray 10 at the feed position 112 are used up and the discharge position is in an empty state, the conversion mechanism can directly transfer the empty tray 10 at the feed position 112 to the discharge position 111. When there are still trays at the discharge position 111, the conversion mechanism transfers the empty tray 10 at the feed position 112 to the temporary storage position 113. When the circulating feeding device 8 removes the full and cleaned tray 10 at the discharge position 111, the conversion mechanism transfers the empty tray 10 at the temporary storage position or the feed position 112 to the discharge position 111. The work efficiency is significantly improved. Driven by the conversion mechanism, fast switching between different workstations is achieved, waiting time is reduced, different functional areas of the loading platform 11 are reasonably divided, and the limited space resources of the loading platform 11 are fully utilized, making the entire system more compact and efficient, which is conducive to improving the transfer efficiency of the tray 10 and realizing the automatic circulation management of the beaker 9. Specifically, the conversion mechanism includes a grabbing assembly 12 and a driving assembly 13 for driving the grabbing assembly 12 to move longitudinally and vertically. The grabbing assembly 12 is used to grab the pallet 10 on the surface of the loading platform 11; the discharge position 111, the feed position 112 and the temporary storage position 113 are longitudinally distributed on the loading platform 11. The grabbing assembly 12 includes a mounting frame, a guide rod longitudinally fixed on the mounting frame, and two claw hooks longitudinally slidably connected to the two ends of the guide rod and arranged oppositely. The mounting frame is provided with a longitudinal driving member for driving the two claw hooks to move closer to or away from each other. The longitudinal driving member specifically adopts a longitudinal cylinder. Both sides of the pallet 10 are provided with card slots adapted to the claw hooks. The opening and closing actions of the two claw hooks are controlled by the longitudinal driving member to achieve a firm grip and safe release of the pallet 10.

[0055] In this embodiment, the driving assembly 13 includes a sliding frame installed on the upper surface of the stage 11 and a vertical guide frame longitudinally slidably connected to the sliding frame, the sliding frame is equipped with a longitudinal linear module for driving the vertical guide frame to move longitudinally, the mounting frame of the grabbing assembly 12 is vertically slidably connected to the vertical guide frame, and the vertical guide frame is equipped with a vertical linear module for driving the mounting frame to move vertically. Accurate positioning and flexible movement of the grabbing assembly 12 on the stage 11 are achieved.

[0056] In order to improve the accuracy of the positioning of the tray 10 at the feeding position 112, a longitudinally arranged positioning member 114 is installed on the upper surface of the loading platform 11. The positioning member 114 is located outside the front edge of the feeding position 112. The positioning member 114 is specifically a stop rod. In addition, the lower end of the vertical guide frame is vertically slidably connected with a pushing assembly 15 for horizontally pushing the tray 10 and a vertical driving member 14 for driving the pushing assembly 15 to rise and fall. The vertical driving member 14 is specifically a vertical cylinder. The pushing assembly 15 includes a fixed plate installed at the telescopic end of the vertical cylinder, a transverse driving member installed at the fixed plate, and a pushing plate fixed at the telescopic end of the transverse cylinder. The transverse driving member is a transverse cylinder. When the moving mechanism places the tray 10 on the upper surface of the loading platform 11 and evacuates the feed position 112, the longitudinal linear module drives the vertical guide frame to move above the feed position 112, the vertical drive member 14 drives the pushing assembly 15 to move down to the rear of the tray 10 at the feed position 112, the transverse drive member extends toward the tray 10, the pushing plate pushes the tray 10, and the support plate contacts the positioning member 114 under the pushing action of the pushing plate, so that the tray 10 is accurately positioned at the feed position 112.

[0057] A positioning member 114 is also provided at the discharge position 111. When the tray 10 at the discharge position 111 is filled with beakers 9, the longitudinal linear module drives the vertical guide frame to move above the discharge position 111, and the vertical driving member 14 drives the pushing assembly 15 to move down to the rear of the tray 10 at the discharge position 111. The transverse driving member extends toward the tray 10, and the pushing plate pushes the tray 10. Under the pushing action of the pushing plate, the tray contacts the positioning member 114 to accurately position the tray 10 at the discharge position 111, so that when the transfer mechanism moves the tray 10 out of the discharge position 111, the positioning hole at the bottom of the tray 10 can be completely plugged into the surface of the bracket, which is conducive to the smooth movement of the tray 10 out of the discharge position 111.

[0058] The temporary storage position 113 on the surface of the loading platform 11 is a flat bearing surface for stacking multiple pallets 10. In order to improve the neatness of the stacking of the pallets 10, multiple horizontal electric push rods are installed at the temporary storage position 113 on the surface of the loading platform 11. The bottommost pallet 10 is positioned by the cooperation of the multiple electric push rods to improve the overall stability of the pallet 10.

[0059] Reference Figures 6 to 8In this embodiment, the automated testing device 3 includes a test bench 31, a slide 33, a stirring mechanism, a camera assembly 37, and a plurality of liquid supply assemblies. A working chamber 32 is installed on the surface of the test bench 31, and a test area 35 is arranged in front of the working chamber 32 for performing automated testing operations. The slide 33 is used to place two beakers 9, one of which is the beaker 9 to be tested, and the other is a cleaned beaker 9. The slide 33 is horizontally slidably connected to the surface of the test bench 31. A translation drive 34 is installed on the test bench 31, and the translation drive 34 is used to drive the slide 33 to slide, so as to drive the beaker 9 to enter and exit the test area 35.

[0060] The slide 33 is provided with two grooves for placing the beaker 9. A horizontally arranged slide bar 36 is installed on the surface of the test bench 31, and the slide bar 36 runs through the bottom of the test area 35. The slide 33 is slidably connected to the slide bar 36, and the translation drive 34 is used to drive the slide 33 to slide along the extension direction of the slide bar 36. The slide 33 is connected to the test bench 31 through the slide bar 36 to ensure that the slide 33 moves smoothly and reliably. The translation drive 34 can be an electric push rod, a cylinder or a screw transmission mechanism, and its function is to push the slide 33 to move forward and backward along the linear guide rail, so as to realize the entry of the beaker 9 into and out of the test area 35.

[0061] In the present embodiment, the liquid supply assembly includes a liquid storage tank, a pump body and a dripper 352. Each liquid storage tank stores a specific reaction solvent, and one of the liquid storage tanks is specifically used to store clean water. The liquid storage tank can be made of polyethylene or glass, with good chemical stability and transparency, which is convenient for observing the liquid level. The pump body is responsible for transporting the solution in the liquid storage tank to the dripper 352, and a peristaltic pump or a diaphragm pump can be selected, both of which can accurately control the flow rate and will not pollute the liquid. The dripper 352 extends above the test area 35 and is arranged vertically downward to ensure that the reaction solvent can be accurately dripped into the beaker 9. The dripper 352 is connected to the pump body through a pipeline, and a control valve is provided on the pipeline to control the flow of the solution.

[0062] In this embodiment, the liquid storage tank and the pump body are installed inside the working chamber 32, and the test area 35 of the working chamber 32 is vertically slidably connected with a slide 351 and a lifting drive 353 for driving the slide 351 to move up and down. A plurality of drippers 352 and a stirring mechanism are fixedly installed on the slide 351, and the drippers 352 are connected to the corresponding pump body through a pipeline, and a control valve is provided on the pipeline to adjust the flow rate of the solution. The stirring mechanism includes a stirring paddle 356 and a stirring drive 355. The stirring paddle 356 is rotatably connected to the slide 351 and is vertically arranged, and can stir the solution by rotation. The stirring paddle 356 can be made of stainless steel, which is both corrosion-resistant and not easy to rust. The stirring drive 355 can be a small motor, which is connected to the stirring paddle 356 through a coupling to drive the stirring paddle 356 to rotate at high speed. In order to prevent the stirring paddle 356 from colliding with the wall of the beaker 9, a buffer gasket can be set at the bottom of the stirring paddle 356.

[0063] The inside of the working chamber 32 is separated from the test area 35 by transparent glass so that the camera assembly 37 can take real-time photos of the changes in the solution in the beaker 9. The camera assembly 37 includes a high-definition camera, an image processor and a data transmission module. The high-definition camera is installed inside the working chamber 32 and faces the position of the beaker 9 in the test area 35 through the transparent glass. The camera has automatic focusing and light compensation functions, and can clearly capture important information such as color changes and reaction time even in low-light environments. The image processor is responsible for receiving the image data collected by the camera, preprocessing it, and extracting key features. The data transmission module sends the processed data to the main control system, and the main control system generates corresponding control instructions based on the received data to regulate the working state of the liquid supply component, the stirring mechanism and the translation drive 34. Specifically, the camera assembly 37 can detect the color change of the solution through the image recognition algorithm, and judge the degree of the chemical reaction through the change of the gray value and the color contrast. At the same time, the turbidity of the solution can also be determined by the edge detection algorithm, and the reaction time can be measured by the timer. These data combined can fully reflect the state change of the solution.

[0064] A pH detection rod is vertically fixed at the slide 351, and the pH detection rod is used to detect the pH value of the solution. The pH detection rod is a common electrode sensor. The vertical pH detection rod 354 arranged at the slide 351 can monitor the pH value change of the solution in the beaker 9 in real time, and timely feedback to the control system so as to more accurately control various parameters in the test process. In this way, the pH information of the solution can be quickly and accurately obtained at different stages of the test, which helps to improve the accuracy of the test results.

[0065] It should be emphasized that in order to improve the accuracy of the test, the working parts of the automatic test device 3 need to be cleaned in time to avoid cross contamination. Therefore, in this embodiment, a tray for placing empty cups is also arranged on the loading platform 11 of the automatic loading and unloading device 1. The automatic cleaning device places most of the cleaned beakers 9 on the tray 10 at the discharge position 111, and also places a small number of cleaned beakers 9 on the tray for placing empty cups. The first automatic cup moving device 6 can also be used to move some of the cleaned beakers 9 at the tray to the transfer table for temporary placement. The second automatic cup moving device 7 can also be used to move the cleaned beakers 9 on the transfer table 5 to the automatic test device for cleaning the internal parts of the automatic test device.

[0066] The specific working process of the automated testing device 3 is: The first cup moving device successively places the beaker 9 to be tested and the cleaned beaker 9 onto the slide table 33 of the automatic testing device 3 .

[0067] When conducting an assay, the translation drive member 34 drives the slide 33 to move so as to move the beaker 9 to be tested into the assay area 35, the stirring mechanism extends downward into the beaker 9 to be tested, and the plurality of liquid supply components inject the solution required for the assay into the beaker 9 below for the assay, the stirring mechanism stirs the solution in the beaker 9 to be tested, and the camera group captures the changes of the solution in the beaker 9 in real time; After the test is completed, the translation drive 34 drives the slide 33 to move, and the cleaned beaker 9 is moved into the test area 35. The stirring mechanism extends downward into the beaker 9, and the liquid supply component storing clean water injects the clean water into the beaker 9 below. The stirring mechanism stirs the clean water in the beaker 9 to clean the stirring mechanism. At this time, the clean water in the beaker 9 becomes turbid and is also treated as waste liquid.

[0068] After the test is finished, the second cup moving device moves the beaker 9 containing the waste liquid to the transfer table 5 as the beaker 9 to be cleaned, waiting for the automatic cleaning device 4 to clean it.

[0069] Reference Figures 9 to 12The automatic cleaning device 4 includes a workbench 41, a frame 42, a transfer mechanism 47, a drain trough 43, a flushing mechanism 44, a drying mechanism 45, a waiting position 46 and two material transfer mechanisms 48. Specifically, a frame 42 is installed at the middle position of the outer side of the workbench 41. The workbench 41 is horizontally divided into a number of work areas at equal intervals, and the several work areas are a drain area 411, a flushing area 412, a drying area 413 and a waiting area 414. Among them, the drain trough 43 is installed in the drain area 411, and is used to place the inverted beaker 9 to be cleaned. The flushing mechanism 44 is installed in the flushing area 412, and is used to clean the inner and outer walls of the beaker 9 in the flushing area 412. The drying mechanism 45 is installed in the drying area 413, and is used to dry the inner and outer walls of the beaker 9 in the drying area 413. The waiting position 46 is composed of a plate-like structure and is horizontally installed in the waiting area 414, and is used to temporarily place the cleaned beaker 9.

[0070] In this embodiment, the transfer mechanism 47 is installed on the frame 42, and the moving range of the transfer mechanism 47 covers each work area, so as to transfer the beaker 9 in the previous work area to the next work area, so that the beaker 9 to be cleaned can be drained, rinsed and dried in sequence and then stored in the waiting position 46.

[0071] In this embodiment, two material moving mechanisms 48 are installed on both sides of the frame 42 and are respectively placed outside the draining area 411 and outside the waiting area 414, wherein the material moving mechanism 48 at the draining area 411 is used to move the beaker 9 to be cleaned into the draining area 411 and turn the beaker 9 to be cleaned upside down into the drain trough 43; the material moving mechanism 48 at the waiting area 414 is used to move the cleaned beaker 9 out of the waiting area 414.

[0072] Specifically, the workbench 41 is used as a basic platform, on which four working areas are divided, namely, a draining area 411, a rinsing area 412, a drying area 413 and a waiting area 414, so as to realize the automation of the whole process from pretreatment to final storage of the beaker 9. The frame 42 supports all moving parts to ensure the stable operation of the system.

[0073] In this embodiment, the drain trough 43 is located in the draining area 411, and three groups of limit claws are installed on the bottom wall of the drain trough 43 at equal intervals in the longitudinal direction, so that three beakers 9 distributed longitudinally can be drained at one time. The drain trough 43 is mainly used to receive the liquid poured from the beaker 9. The drain trough 43 is designed to have a sufficient volume to accommodate the waste liquid after multiple cleanings. In addition, a drainage hole is provided at the bottom of the drain trough 43 to facilitate the discharge of waste liquid and keep the working environment clean.

[0074] In this embodiment, the flushing mechanism 44 mainly includes a flushing trough 443, a first nozzle 445, a water shield 442, a second nozzle 444, a first driving member 441 and a water supply assembly. Specifically, the flushing trough 443 is installed at the flushing area 412 and a drainage hole is installed at the bottom. The inner bottom wall of the flushing trough 443 is also fixed with three longitudinally arranged limit claws. The flushing mechanism 44 can flush three beakers 9 at a time. The inner bottom wall of the flushing trough 443 is provided with a first nozzle 445. The beaker 9 to be flushed is placed upside down in the flushing trough 443 and is covered above the first nozzle 445. The spray range of the first nozzle 445 covers the inner wall of the beaker 9. Among them, the water shield 442 is used to cover the outer periphery of the beaker 9 to be rinsed to form a relatively closed rinsing environment. When the beaker 9 moves from the draining area 411 into the rinsing area 412, the first driving member 441 drives the water shield 442 to move downward, so that the water shield 442 fits tightly with the rinsing tank 443 to form a sealed space, which effectively prevents water from splashing out during the rinsing stage. The first driving member 441 is specifically a cylinder installed on the bracket above the workbench 41 and arranged vertically downward, and the piston rod of the cylinder is fixed to the top of the water shield 442. In addition, a second nozzle 444 is installed on the top of the water shield 442, and the second nozzle 444 extends to the inner top wall of the water shield 442 and is arranged vertically downward. The spray range of the second nozzle 444 covers the outer wall of the beaker 9. The sewage generated by cleaning is discharged through the drain hole.

[0075] In this embodiment, the water supply assembly is composed of a water tank, a water pump and a hose commonly used in cleaning equipment, and the hose of the water supply assembly is connected to the first nozzle 445 and the second nozzle 444 to ensure that the cleaning liquid is evenly sprayed and thoroughly removes the dirt on the inner and outer walls of the beaker 9. This design not only improves the cleaning effect, but also reduces water consumption, which is energy-saving and environmentally friendly.

[0076] In this embodiment, the drying mechanism 45 includes a drying groove 453, a first air jet 455, a shielding cover 452, a second air jet 454, a second driving member 451 and an air supply assembly. The drying groove 453 is installed in the drying area 413, and the inner bottom wall of the drying groove 453 is also fixed with three longitudinally arranged limit claws. The drying mechanism 45 can dry three beakers 9 at a time. The inner bottom wall of the drying groove 453 is installed with a first air jet 455 arranged upward. When the beaker 9 is moved from the rinsing area 412 to the drying area 413 after rinsing, the beaker 9 is placed in an inverted state in the drying groove 453 and is covered above the first air jet 455. The spray range of the first air jet 455 covers the inner wall of the beaker 9. The shielding cover 452 is used to cover the outer periphery of the beaker 9 to be dried, and a second air jet 454 is arranged inside, and the spray range of the second air jet 454 covers the outer wall of the beaker 9. Among them, when the beaker 9 is moved from the rinsing area 412 to the drying area 413 under the drive of the moving mechanism, the first driving member 441 drives the water shield 442 to move downward, so that the shielding cover 452 is tightly fitted with the drying tank 453 to form a sealed space. The first driving member 441 is specifically a cylinder installed on the bracket above the workbench 41 and arranged vertically downward, and the piston rod of the cylinder is fixed to the top of the shielding cover 452. The spray range of the second jet port 454 covers the outer wall of the beaker 9. The bottom of the drying area 413 is provided with air holes to allow the internal gas of the shielding cover 452 to be discharged.

[0077] In this embodiment, the air supply component is composed of a blower, a heating box and an air supply pipe commonly used in drying equipment. The air supply pipe of the air supply component is connected to the first jet port 455 and the second jet port 454. The air supply component continuously supplies drying gas to the first jet port 455 and the second jet port 454, thereby ensuring the continuity and stability of the entire drying process.

[0078] In order to improve the stability of the beaker 9 during cleaning, a first push rod 446 is vertically arranged on the inner top wall of the water shield 442. When the water shield 442 is arranged on the outer periphery of the beaker 9, the lower end of the first push rod 446 abuts against the outer bottom wall of the beaker 9. In addition, a second push rod 456 is vertically arranged on the inner top wall of the shielding cover 452. When the shielding cover 452 is arranged on the outer periphery of the beaker 9, the lower end of the second push rod 456 abuts against the outer bottom wall of the beaker 9. The design of the push rod can accurately position and firmly support the beaker 9, preventing it from shaking or shifting during the rinsing and drying process, which is conducive to improving the cleaning effect and reliability.

[0079] In this embodiment, the transfer mechanism 47 includes a horizontal frame 472 and a plurality of first suction cups 473. The workbench 41 is provided with a third driving member 471 for driving the horizontal frame 472 to move vertically and horizontally. The third driving member 471 adopts a conventional rectangular coordinate manipulator, and realizes the purpose of precise movement of the horizontal frame 472 through the cooperation of the vertical linear module and the horizontal linear module. The horizontal frame 472 can move vertically and horizontally through the third driving member 471. In this embodiment, longitudinal rods 474 are respectively provided at both ends and the midpoint of the horizontal frame 472, and each longitudinal rod 474 is installed with three first suction cups 473, and the three first suction cups 473 are distributed longitudinally. When the transfer mechanism 47 performs the beaker 9 transfer step, the third driving member 471 drives the cross frame 472 to move horizontally, so that the suction cups of the three longitudinal rods 474 move to the draining area 411, the rinsing area 412 and the drying area 413 respectively, and each suction cup faces downward to the beaker 9 in the corresponding working area, and then the third driving member 471 drives the cross frame 472 to move downward, and the first suction cups 473 on the three longitudinal rods 474 respectively absorb the beaker 9 in the draining area 411, the rinsing area 412 and the drying area 413, and then the third driving member 471 drives The horizontal frame 472 moves upward to suck up the beaker 9, and then driven by the third driving member 471, the horizontal frame 472 moves toward the waiting area 414, and the beakers 9 in the three vertical rows move horizontally synchronously to transfer the beakers 9 in the draining area 411 to the rinsing area 412, transfer the beakers 9 in the rinsing area 412 to the drying area, and transfer the beakers 9 in the drying area to the waiting area 414, thereby achieving the purpose of synchronously transferring the beakers 9 in multiple working areas, thereby reducing the number of transfer mechanisms 47, reducing manual intervention, and improving efficiency.

[0080] In this embodiment, the waiting position 46 is equipped with three longitudinally distributed limiting claws, which can wait for three beakers 9 at a time so that the material transfer mechanism 48 can accurately grasp and transfer them.

[0081] Reference Fig.13 and Fig.14The material moving mechanism 48 located outside the draining area 411 and the material moving mechanism 48 located outside the waiting area 414 have the same structure. Specifically, the material moving mechanism 48 includes a moving seat 484, a flip seat 485, a flip frame 486, a second suction cup 489, a clamping assembly 482 and a fourth driving member 481. The moving seat 484 is vertically slidably connected to the frame body 42, and the frame body 42 is equipped with a moving driving member for driving the moving seat 484 to move up and down, and the moving driving member adopts a conventional vertical linear module. In addition, the flip seat 485 is hinged to the moving seat 484, and the axis of rotation of the flip seat 485 is vertically arranged. The moving seat 484 is equipped with a first flip driving member 488 for driving the flip seat 485 to flip sideways, and the first flip driving member 488 adopts a conventional motor. The flip frame 486 is rotatably connected to the flip seat 485, the rotation axis of the flip frame 486 is horizontally arranged, and the flip frame 486 is used to place the beaker 9. In this embodiment, the flip frame 486 is provided with three slots for placing the beaker 9. A second suction cup 489 for adsorbing and fixing the beaker 9 is installed at the bottom of the slot of the flip frame 486. In addition, the flip seat 485 is equipped with a second flip driving member 487 for driving the flip frame 486 to flip up and down, and the second flip driving member 487 is a motor.

[0082] The clamping assembly 482 uses a conventional clamping claw. In this embodiment, there are three clamping claws in total and they are distributed laterally. They are used to transfer the beaker 9 containing waste liquid on the transfer table 5 to the slot on the flip frame 486, wherein the frame body 42 is installed with a fourth driving member 481 for driving the clamping assembly 482 to move longitudinally and vertically. The fourth driving member 481 uses a conventional rectangular coordinate manipulator, which is composed of a linear module arranged longitudinally and a linear module arranged vertically.

[0083] When the material transfer mechanism 48 delivers the beaker 9 to be cleaned to the draining area 411, the overturning frame 486 waits for the beaker 9 containing waste liquid to come over in a horizontal state. At this time, the clamping assembly 482, driven by the fourth driving member 481, clamps the beaker 9 containing waste liquid to the overturning frame 486 with the opening facing upward. In this embodiment, a collection tank 415 for collecting the solution is provided outside the draining area 411, and the collection tank 415 is movable. The overturning frame 486 is located above the collection tank 415; the overturning frame 486 is driven by the second overturning driving member 487 to turn down so that the opening of the beaker 9 faces downward, thereby pouring the waste liquid in the beaker 9 into the collection tank 415.

[0084] Then, the turning seat 485 is turned sideways by 90 degrees under the drive of the first turning driving member 488, and the turning frame 486 is horizontally swung to above the drain trough 43 at the draining area 411. At this time, the turning frame 486 is switched from the horizontal direction to the vertical direction, and the beaker 9 on the turning frame 486 is directly facing the limit claw on the drain trough. The moving seat 484 is driven by the moving driving member to move downward to place the beaker 9 upside down in the drain trough 43 and position it through the limit claw.

[0085] When the material transfer mechanism 48 takes the cleaned beaker 9 out of the waiting area 414, the flip frame 486 is flipped down by the second flip driving member 487, and the slot is set downward. Then, the flip seat 485 is flipped 90 degrees by the first flip driving member 488 to swing the flip frame 486 horizontally to above the waiting position 46 in the waiting area 414. At this time, the flip frame 486 is switched from the horizontal direction to the vertical direction, and the slot on the flip frame 486 is directly opposite to the beaker 9 on the waiting position 46. Then, the moving seat 484 is moved downward by the moving driving member to plug and match the slot of the flip frame 486 with the inverted beaker 9, and the second suction cup 489 of the flip frame 486 adsorbs the outer bottom wall of the beaker 9.

[0086] Then the turning frame 486 returns along the original path, thereby taking the cleaned beaker 9 out of the waiting area 414. Finally, the gripping assembly 12, driven by the fourth driving member 481, clamps the cleaned beaker 9 out of the turning frame 486 with the opening facing upward, and transfers it longitudinally to the tray 10 at the discharge position 111 of the automatic loading and unloading device 1. This linkage mechanism ensures the seamless connection of the beaker 9 between various processes, which can improve the automation level of the entire system.

[0087] In this embodiment, the first suction cup 473 and the second suction cup 489 are both electric suction cups, which can realize automatic adsorption and release functions.

[0088] The implementation principle of the automatic testing system for chemical liquids used in PBC board processing is: In this system, each beaker to be tested is labeled with an identifiable label corresponding to the solution contained therein, and there are two beaker circulation routes in the system, one for chemical experiments and the other for equipment cleaning.

[0089] In the beaker circulation route used for chemical experiments, the circulating feeding device 8 carries the beaker to be tested to the sampling system to load the corresponding solution to be tested, and then feeds the beaker 9 to be tested into the feed position 112 of the automatic loading and unloading device 1. The first automatic cup moving device 6 is responsible for transferring the beaker 9 to be tested at the feed position from the feed position 112 to the transfer table 5. It should be noted that an identification device is installed on the loading platform 11 of the automatic loading and unloading device 1 for identifying the label corresponding to the beaker, and the identification device can use the RFID identification principle for accurate identification. Before the first automatic cup moving device 6 moves the beaker 9 to be tested to the transfer table 5, it needs to be moved to the first identification device for identification confirmation, and then the first automatic cup moving device 6 moves it to the corresponding position at the transfer table 5 after confirmation.

[0090] Then, the second automatic cup moving device 7 is responsible for sending the beaker 9 to be tested on the transfer table 5 to the automatic testing device 3 for testing. It should be noted that the loading table 11 of the automatic loading and unloading device 1 is also equipped with an identification device. Before the second automatic cup moving device 7 moves the beaker 9 to be tested to the transfer table 5, the beaker 9 needs to be moved to the identification device on the transfer table for secondary identification confirmation. After confirmation, the second automatic cup moving device 7 moves the beaker 9 to the corresponding automatic testing device 3 for experiment, or moves it to the static table for heating or static.

[0091] After the test is completed, the second automatic cup transfer device 7 returns the beaker 9 containing the waste liquid to the transfer table 5. Next, the automatic cleaning device 4 grabs the beaker 9 containing the waste liquid on the transfer table 5, moves it to the inside of the automatic cleaning device 4 for cleaning, and transfers the cleaned beaker 9 to the discharge position 111 of the automatic loading and unloading device 1.

[0092] After the tray 10 of the discharge position 111 of the automatic loading and unloading device 1 is fully loaded with the cleaned beakers 9, the circulating feeding device 8 delivers the cleaned beakers 9 from the discharge position 111, and performs on-site sampling through an external sampling system, and the beaker 9 containing the solution to be tested is the beaker 9 to be tested. Then, the circulating feeding device 8 continues to deliver the beaker 9 to be tested to the feed position 112 of the automatic loading and unloading device, thereby forming a complete cycle process of the chemical experiment.

[0093] In the beaker circulation route used for equipment cleaning, the automatic cleaning device 4 transfers some of the cleaned beakers to the tray for placing empty cups in the automatic loading and unloading device 1, and then moves them to the transfer table 5 for temporarily storing empty cups through the first automatic cup moving device 6. The second automatic cup moving device 7 moves the empty cups to the automatic testing device 3 for self-cleaning of the stirring mechanism in the automatic testing device 3.

[0094] The entire process does not require human intervention, which greatly improves the test efficiency and system reliability, while also reducing errors and safety hazards caused by human operation.

[0095] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
