Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0029] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0030] Based on the above objectives, the first aspect of the present invention provides an embodiment of a method for preparing paint coatings. Figure 1 The diagram shown is a schematic representation of an embodiment of the paint / coating preparation method provided by the present invention. For example... Figure 1 As shown, the method for preparing paint coatings according to an embodiment of the present invention includes the following steps:

[0031] 001. Load each type of raw material into its corresponding raw material syringe, and store the raw material syringes in categories;

[0032] In this embodiment, the raw material storage module stores multiple raw material syringes, with each type of raw material loaded into its corresponding syringe. Each raw material syringe is marked with an identification code for easy traceability and identification. The required syringes containing various raw materials are placed at the loading station, and then at the barcode reading station. After the system scans and identifies the barcodes, the raw materials are categorized and placed in specific locations. For example, syringes containing raw materials with the same composition are placed in the same area, or syringes containing raw materials of the same color are placed in the same area. This disclosure does not limit the method of categorization and storage.

[0033] 002. In response to receiving a paint preparation instruction, the target raw material syringe is selected based on the paint preparation instruction, and the raw material in the target raw material syringe is quantitatively injected into the syringe, and the syringe is transported to the mixing area along the X-direction conveyor line.

[0034] In this embodiment, after receiving the paint preparation command from the central control terminal, the required raw materials are placed in the paint mixing station, and an empty syringe is placed on the electronic balance of the paint mixing station. The paint rotary mixing mechanism then injects the required raw materials into the syringe in a quantitative manner.

[0035] 003. Move the stirring mechanism along the Y direction to directly above the syringe within the stirring zone to stir the raw material in the syringe, and then move it away along the Y direction. Move the viscosity testing mechanism along the Y direction to directly above the syringe within the stirring zone to perform viscosity testing; and

[0036] In this embodiment, the syringe containing the prepared ingredients is placed in the mixing station for vacuum mixing, and the paint viscosity is tested after mixing is completed.

[0037] 004. In response to the viscosity test of the raw material in the syringe, the syringe is conveyed to the syringe manufacturing area along the X-direction conveyor line, and a piston rod is installed on the syringe to obtain a paint / coating syringe. The piston rod has an axial through hole for discharging paint / coating when the piston rod and the syringe move axially relative to each other; wherein, the X-direction and the Y-direction are perpendicular to each other.

[0038] In this embodiment, if the viscosity is suitable, the paint preparation is complete. The prepared paint is then conveyed to the piston rod pressing station, and the piston rod is pressed into the syringe.

[0039] In some embodiments of the present invention, the method further includes: in response to the raw material in the syringe failing the viscosity test, continuing to stir or adding raw material.

[0040] In this embodiment, after the stirring mechanism completes the stirring, the viscosity of the paint coating can be detected by a viscosity testing mechanism. For example, the viscosity testing mechanism may include a motor and a viscosity testing component, which may include a rotor and a stirring rod, etc. This disclosure does not limit the type of viscosity testing component. The viscosity of the paint coating can be determined by rotating the viscosity testing component in the paint coating with the motor and detecting the resistance received during rotation. If the viscosity of the paint coating is too high, a thinner can be added to the syringe, and the mixture can be stirred again and the viscosity can be tested again until it passes the viscosity test. The above viscosity test can avoid the paint coating being too viscous, which would make sample preparation difficult when using the paint coating later.

[0041] In some embodiments of the present invention, the method further includes: transferring the paint / coating syringe to the scraping area / spraying area / manual sample preparation output port based on the sample preparation program instructions; and placing the used raw material syringe into the waste syringe box.

[0042] In this embodiment, to ensure the complete preservation of information about the paint / coating syringe, an identification code, such as a QR code or barcode, can be sprayed onto the syringe using a coding mechanism. This allows the information of the paint / coating syringe to be obtained by reading the identification code. In this example, the type of paint is marked on the syringe, and the sample is transferred to the scraping / spraying area or the manual sample preparation output port according to the sample preparation procedure instructions. Used raw material syringes are placed in a waste syringe container, which can hold several used raw material syringes. This facilitates the centralized collection and cleaning of used raw material syringes, allowing for their reuse and reducing material waste.

[0043] In some embodiments of the present invention, classifying and storing several raw material syringes includes: driving a syringe positioning plate to rotate by a rotary motor, causing the raw material syringes placed on the syringe positioning plate to rotate; reading the identification code sprayed on the raw material syringes by a code reader during the rotation of the raw material syringes, and classifying and storing the raw material syringes by a raw material positioning and transfer mechanism.

[0044] In this embodiment, the raw material storage platform can store multiple raw material syringes. In this example, it can store 20 raw material syringes. This disclosure does not limit the capacity of the raw material storage platform. Each raw material syringe can be affixed or sprayed with an identification code, such as a QR code or barcode. The identification code can be used to identify the information of the raw material in the raw material syringe, such as the type, color, viscosity, etc. The multiple raw material syringes placed in the raw material storage platform are respectively placed into the code reading mechanism for code reading. For example, a corresponding quick-change gripper can be selected according to different raw material syringes, or an appropriate quick-change gripper can be selected according to the syringe barrel diameter, etc., so that the raw material syringe can be grasped and placed in front of the code reading mechanism for code reading. After code reading, the information of the raw material in the raw material syringe is determined, so that it can be classified according to the information of the raw material and stored in the raw material positioning and transfer mechanism. In this example, raw material syringes of the same color can be placed in the same row in the raw material positioning and transfer mechanism, or raw material syringes of the same type can be placed in the same row in the raw material positioning and transfer mechanism, etc. This disclosure does not limit the specific method of classification and storage. Since the identification code (e.g., QR code or barcode) sprayed on the syringe of the raw material syringe may not be facing the reader, a rotary motor can be used to drive the syringe positioning plate to rotate. For example, the syringe positioning plate can be driven to rotate by a synchronous belt, thereby driving the raw material syringe to rotate. During the rotation of the raw material syringe, the reader can read the identification code of the raw material syringe when the identification code is facing the reader.

[0045] In some embodiments of the present invention, selecting a target raw material syringe based on a paint / coating preparation instruction and quantitatively injecting the raw material from the target raw material syringe into the syringe includes: rotating the target raw material syringe above the syringe via a turntable of a rotary dispensing mechanism; and injecting the amount of raw material from the target raw material syringe corresponding to the paint / coating preparation instruction into the syringe.

[0046] The rotary dispensing mechanism weighs the raw material injected into the syringe using a weighing sensor and controls the injection speed of the raw material using a raw material syringe pressing mechanism.

[0047] The injection rate of raw materials is determined by the formula. Sure;

[0048] Where V is the pressing speed of the raw material syringe pressing mechanism, m1 and m2 are the weights of raw material injected into the syringe per unit time, with m1 > m2, and M is the dosage corresponding to the paint / coating preparation instruction. T R is the variable speed threshold, R is the syringe radius, ρ is the raw material density, and m is the raw material weight measured by the weighing sensor.

[0049] In this embodiment, when M T When the relationships between M and m1 and m2 are as follows, the present invention can more accurately control the amount of raw material injected into the syringe.

[0050] M T = a*M, where a≤0.3, when M≤100, a=0.2 is preferred, when 100<M, a=0.01 is preferred.

[0051] m1 = b * m2, where 5 ≤ k2 ≤ 20, and b = 10 is preferred.

[0052] In this embodiment, M can be set to 500g. T The values ​​can be set to 5g, m1 can be set to 5g / s, m2 can be set to 0.5g / s, R can be set to 25mm, and ρ can be set to 1.5g / cm. 3 When the difference between the raw material weight measured by the weight sensor and the preset amount is greater than 5 grams, the pressing speed of the syringe pressure plate is 1.7 (mm / s). When the difference between the raw material weight measured by the weight sensor and the preset amount is less than or equal to 5 grams, the pressing speed of the syringe pressure plate is 0.17 (mm / s).

[0053] In this embodiment, M can be set to 50g. T The values ​​can be set to 5g, m1 can be set to 5g / s, m2 can be set to 0.25g / s, R can be set to 25mm, and ρ can be set to 1.5g / cm. 3When the difference between the raw material weight measured by the weight sensor and the preset amount is greater than 5 grams, the pressing speed of the syringe pressure plate is 1.7 (mm / s). When the difference between the raw material weight measured by the weight sensor and the preset amount is less than or equal to 5 grams, the pressing speed of the syringe pressure plate is 0.08 (mm / s).

[0054] In this embodiment, the syringe can be placed on a weighing sensor below the rotating dispensing mechanism. When the raw material in the target raw material syringe is injected into the syringe, the target raw material syringe can be rotated to a position directly above the syringe, and the target raw material syringe is pushed by the raw material syringe pressing mechanism to dispense the amount corresponding to the paint / coating preparation instruction. This amount is positively correlated with the pushing distance of the piston rod of the target raw material syringe. By controlling the pushing distance of the piston rod of the target raw material syringe, the amount of raw material can be precisely controlled to match the amount required by the paint / coating preparation instruction. Furthermore, to control the amount more precisely, the weight sensor constantly weighs the syringe and the raw material contained inside. When the weight of the raw material measured by the weight sensor reaches a certain value (mm), the weight is adjusted accordingly. T Previously, the difference from the preset dosage was M. T Previously, the pressing speed could be increased at a faster rate, thus improving pressing speed and configuration efficiency. When the weight of the raw material measured by the weight sensor reaches MM... T Then, the material is pressed down at a slower speed to more precisely control the output of the raw material. The injection of raw material is stopped when the weight corresponding to the paint / coating preparation instruction is reached, further improving the accuracy of the raw material dosage.

[0055] In this embodiment, when preparing paint coatings, the target raw material syringe can be transferred to the dispensing module for dispensing. A robot quick-change gripper is selected based on the type of the target raw material syringe; the robot quick-change gripper picks up the target raw material syringe and transfers it to the dispensing module. The paint coating preparation instruction may include the type, ratio, preparation method, amount of thinner added, and information such as the test plate specifications and model required for subsequent use after the paint coating preparation process is completed. This disclosure does not limit the specific content included in the paint coating preparation instruction. After determining the target raw material syringe required for preparing the paint coating through the paint coating preparation instruction, an appropriate robot quick-change gripper can be selected based on the type of the target raw material syringe (e.g., according to the syringe barrel diameter) to pick up the target raw material syringe.

[0056] In this embodiment, the required raw material type is determined according to the paint / coating preparation instruction, and the identification code of each raw material syringe is read to determine which of the raw material syringes(s) is the required raw material syringe(s). After determining the target raw material syringe(s), it is placed in the dispensing module. The dispensing module determines the amount of raw material in each target raw material syringe according to the paint / coating preparation instruction, and accurately dispenses the appropriate amount of raw material into the syringe.

[0057] In this embodiment, the rotary dispensing mechanism includes multiple placement positions for raw material syringes on its turntable, used to hold multiple target raw material syringes. According to the paint / coating preparation instructions, various types of target raw material syringes can be placed in the designated positions. The rotary dispensing mechanism then aligns the target raw material syringes at each position with the syringe according to the paint / coating preparation instructions, and dispenses a predetermined amount of raw material from each syringe. The syringe can be placed at a preset position below the rotary dispensing mechanism. When injecting raw material from the target raw material syringe into the syringe, the placement position of the target raw material syringe can be rotated to directly above the syringe, pushing the target raw material syringe to dispense the amount corresponding to the paint / coating preparation instructions. This amount is positively correlated with the pushing distance of the piston rod of the target raw material syringe. By controlling the pushing distance of the piston rod of the target raw material syringe, the amount of raw material can be precisely controlled to match the amount required by the paint / coating preparation instructions. Furthermore, to control the dosage more precisely, the rotary dispensing mechanism may also include a weight sensor. The syringe can be placed on the weight sensor to weigh the syringe and the raw materials inside it at all times. When the weight corresponding to the paint preparation instruction is reached, the injection of raw materials can be stopped, thereby further improving the accuracy of the raw material dosage.

[0058] In some embodiments of the present invention, the weight sensor in the rotary batching mechanism may also be replaced by an electronic scale.

[0059] In some embodiments of the present invention, stirring the raw materials in the syringe and performing a viscosity test includes: sealing the syringe, vacuuming the syringe using a vacuuming mechanism, vacuum stirring the mixture of multiple raw materials in the syringe using a stirring mechanism, wherein the stirring mechanism drives the dispersing disk to rotate via a stirring motor to vacuum stir the mixture of multiple raw materials in the syringe, and detecting the viscosity of the paint coating obtained after stirring using a viscosity testing mechanism.

[0060] In this embodiment, the raw materials in the syringe are stirred by a motor and a stirring component. The stirring component may include a stirring rod, a dispersing disc, etc., and this disclosure does not limit the specific type of the stirring component. Further, after the syringe is sealed by the stirring mechanism, a vacuuming mechanism is used to vacuum the syringe and stir the mixture of various raw materials in the syringe. In this example, the stirring mechanism may be located on a linear module in the Y direction. The lower part of the stirring mechanism may include a sealing ring or other sealing mechanism. The stirring mechanism can move along the linear module in the Y direction to directly above the syringe and move downwards, causing the sealing ring to press against the syringe, thereby sealing the syringe. Then, the syringe is vacuumed by the vacuuming mechanism. After vacuuming, stirring can be performed by the dispersing disc, i.e., vacuum stirring. The vacuum stirring process allows the syringe to be stirred in a vacuum environment, thereby reducing air bubbles introduced during stirring in air. This results in a more uniform and complete paint film thickness when the paint is scraped or sprayed, improving the appearance quality of the paint film.

[0061] In this embodiment, after the stirring mechanism completes its stirring, it can rise and move in the Y direction, moving away from directly above the syringe. Subsequently, the viscosity of the paint / coating can be detected by a viscosity testing mechanism. For example, the viscosity testing mechanism can be positioned on a linear module in the Y direction and moved along the linear module to directly above the syringe, where a viscosity test can be performed. The viscosity testing mechanism may include a motor and a viscosity testing component, which may include a rotor and a stirring rod, etc. This disclosure does not limit the type of viscosity testing component. The viscosity testing mechanism can descend, immersing the viscosity testing component in the liquid surface. The motor can drive the viscosity testing component to rotate in the paint / coating, and the resistance encountered during rotation can be detected to determine the viscosity of the paint / coating. If the viscosity of the paint / coating is too high, a thinner can be added to the syringe, and the mixture can be stirred again, and the viscosity test can be repeated until it passes the viscosity test. This viscosity test avoids excessively high paint / coating viscosity, which could cause difficulties in sample preparation when using the paint / coating later.

[0062] In some embodiments of the present invention, to prevent residual materials on the stirring mechanism and viscosity testing mechanism from contaminating the materials to be stirred subsequently and affecting the quality of the paint, the present invention also includes a cleaning mechanism for cleaning the stirring mechanism and viscosity testing mechanism. The cleaning mechanism is as follows: Figure 5 The cleaning mechanism includes a spin-drying tank 51, a cleaning liquid tank 52, and a clean water tank 53. The spin-drying tank can be empty, the cleaning liquid tank contains cleaning liquid, and the clean water tank contains clean water. The spin-drying tank 51, the cleaning liquid tank 52, and the clean water tank 53 are aligned in the front-to-back direction. Furthermore, the spin-drying tank 51, the cleaning liquid tank 52, and the clean water tank 53 are comprised in two sets, which can be installed side-by-side on the mounting base 57. Furthermore, the cleaning liquid tank 52 and the clean water tank 53 can be made transparent.

[0063] In some embodiments of the present invention, liquid circulation components may be provided on the cleaning fluid tank 52 and the clean water tank 53 for circulating the internal liquids (e.g., cleaning fluid or clean water). Furthermore, the liquid circulation components may be disposed on the outer walls of the cleaning fluid tank 52 and the clean water tank 53 to prevent the stirring mechanism or viscosity testing mechanism from contacting and damaging the liquid circulation components when it enters the cleaning fluid tank 52 and the clean water tank 53.

[0064] In some embodiments of the present invention, the liquid circulation assembly includes an inlet 54, a drain 55, a level switch 56, and a turbidity sensor; the turbidity sensor is used to detect the turbidity of the liquid in the cleaning liquid tank 52 or the clean water tank 53; the drain 55 is used to discharge the liquid in the cleaning liquid tank 52 or the clean water tank 53 when the turbidity meets the turbidity condition; the inlet 54 is used to inject liquid into the cleaning liquid tank 52 or the clean water tank 53; the level switch 56 is used to close the inlet 54 when the liquid level in the cleaning liquid tank 52 or the clean water tank 53 reaches a preset height.

[0065] In one possible implementation, the turbidity sensor in the liquid circulation assembly can be a fiber optic sensor. This sensor detects the turbidity of the liquid in the cleaning fluid tank 52 and the clean water tank 53, and circulates the liquid when the turbidity meets a certain condition (e.g., when the fiber optic sensor detects that the transmittance is below a threshold), i.e., draining the turbid liquid and injecting new liquid. In another example, a turbidity sensor may not be provided, and the liquid in the cleaning fluid tank 11 and the clean water tank 10 may be circulated periodically. This disclosure does not limit this.

[0066] By incorporating a spin-drying tank 51, large pieces of raw material can fall into it, preventing blockages in the circulation pipes of the cleaning fluid tank 52 and the clean water tank 53. When the amount of raw material in the spin-drying tank 51 is large, the tank can be replaced. The cleaning fluid tank 52 enhances the cleaning effect on the raw material, preventing residual material on the stirring mechanism and / or viscosity testing mechanism from contaminating subsequent materials and affecting the quality of the paint. The clean water tank 52 effectively cleans residual raw material and cleaning fluid from the stirring mechanism and / or viscosity testing mechanism, preventing contamination of subsequent materials and affecting the quality of the paint. The liquid circulation assembly enables automatic circulation of the liquid in the cleaning fluid tank 52 and the clean water tank 53, maintaining the cleanliness of the liquid in these tanks.

[0067] In some embodiments of the present invention, installing a piston rod on a syringe to obtain a paint injector includes: pressing the piston rod down through a piston rod pressing mechanism to insert it into the syringe; detecting the presence of paint at the top end of the axial through hole of the piston rod using a fiber optic sensor; stopping the pressing down of the piston rod in response to the presence of paint at the top end of the axial through hole of the piston rod; and spraying an identification code onto the syringe using a coding mechanism to obtain a paint injector marked with the type of paint.

[0068] In some embodiments of the present invention, such as Figure 6 As shown, the syringe manufacturing mechanism includes: a first linear module 66, a first cylinder 64, a positioning plate 62, and a clamping plate 65. The first linear module 66 is a vertical linear module used to carry the piston rod 61 in a vertical direction. The piston rod 61 has an axial through hole. The positioning plate 62 is disposed on the first linear module 66 and is used to place the piston rod 61. The first cylinder 64 is used to drive the clamping plate 65, so that the piston rod 61 is fastened to the positioning plate 62, and the piston rod 61 moves downward along the first linear module 66, allowing the piston rod 61 to enter the syringe. In the example, the positioning plate 62 can move along the first linear module 66 via a second cylinder 67, that is, carry the piston rod 61 along the first linear module 66, allowing the piston rod 61 to move downward into the syringe. Furthermore, in order to more accurately press the piston rod into the syringe, the piston rod is made transparent, and a fiber optic sensor 63 is provided. The sensor 63 is used to detect whether there is paint coating at the top of the axial through hole of the piston rod 61. Furthermore, the fiber optic sensor 63 is mounted on the clamping plate 65.

[0069] In some embodiments of the present invention, after the robot places the piston rod 61 on the positioning plate 62, the first cylinder 64 drives the clamping plate 65 to press the piston rod 61, and the second cylinder 67 drives the positioning plate 62 to move downward, causing the piston rod 61 to move downward and enter the syringe. After the piston rod 61 reaches the liquid surface in the syringe, the paint coating in the syringe will rise through the axial through hole of the piston rod 61, that is, be discharged through the axial through hole. In other words, when the paint coating is discharged through the axial through hole, the piston rod 61 has reached the liquid surface in the syringe. At this time, the air in the syringe has been emptied, and the piston rod 61 can stop descending. The presence of paint coating discharged through the axial through hole can be detected by the fiber optic sensor 63. For example, when the paint coating reaches the top of the axial through hole, the paint coating will block the light of the fiber optic sensor 63, causing the light transmittance to decrease. The fiber optic sensor 63 can determine that the paint coating has reached the top of the axial through hole when it detects the decrease in light transmittance, that is, the piston rod has reached the liquid surface of the paint coating. At this time, the piston rod 61 can stop descending, and the paint coating syringe can be obtained.

[0070] Furthermore, to improve the manufacturing efficiency of the paint syringe and reduce the probability of paint overflowing rapidly from the top of the axial through-hole, the speed at which the piston rod is pressed down can be controlled. For example, before the piston rod enters the syringe, the pressing speed of the piston rod can be faster, that is, the second cylinder 67 can drive the positioning plate 62 downwards more quickly, thereby improving manufacturing efficiency. After the piston rod enters the syringe, the pressing speed of the piston rod can be slower, that is, the second cylinder 67 can drive the positioning plate 62 downwards more slowly, thereby reducing the probability of paint overflowing rapidly from the top of the axial through-hole. In the example, the height of the syringe can be set so that the second cylinder 67 can press down rapidly before driving the positioning plate 62 downwards to the height of the syringe, and the pressing speed can be reduced when it is below the height of the syringe, for example, reduced to 1 / 10 of the previous speed. This disclosure does not limit the specific values ​​of the pressing speed before and after descending to the height of the syringe. In this way, air in the syringe can be expelled, reducing air bubbles in the paint, which is beneficial for accurately controlling the amount of paint used in subsequent use.

[0071] In this embodiment, after the viscosity test is passed, a piston rod can be attached to the syringe. This piston rod can be an axially through-hole piston rod. After being attached to the syringe, it forms a paint / coating syringe, that is, a syringe that holds the prepared paint / coating. When using the paint / coating in subsequent processes, the piston rod can be moved axially within the syringe to dispense the paint / coating. The distance the piston rod moves is proportional to the amount of paint / coating used. Therefore, using a paint / coating syringe allows for precise control of the amount of paint / coating used.

[0072] In this embodiment, to ensure the complete preservation of information about the paint / coating syringe, an identification code, such as a QR code or barcode, can be sprayed onto the syringe using a coding mechanism. This allows the information of the paint / coating syringe to be obtained by reading the identification code during subsequent use. In this example, if a power outage occurs during use, the information about the paint / coating syringe, such as its composition and proportions, can be retrieved by reading the code. In subsequent use, the manufactured paint / coating syringe can be sent to a spraying or scraping mechanism for use, or it can be placed in a paint / coating syringe storage facility, awaiting manual removal for other purposes.

[0073] In some embodiments of the present invention, used raw material syringes are collected using a waste syringe box. After the raw material in the target raw material syringe on the rotating dispensing mechanism is used up, the used raw material syringes can be collected into the waste syringe box. In the example, the waste syringe box can hold 12 used raw material syringes, which facilitates the centralized collection and cleaning of the used raw material syringes, thereby enabling these raw material syringes to be reused and reducing material waste.

[0074] In some embodiments of the present invention, each process in the above-described paint preparation method can be recorded and stored in a database, and this information can be read by reading the identification code of the paint syringe. For example, the type of syringe for selecting the target raw material, the selection time, the time of the batching module for batching, the time of the stirring module for stirring and viscosity testing, the amount of diluent added during the viscosity testing, the time of the piston rod installation in the syringe manufacturing module, and the time of spraying the identification code, etc., this disclosure does not limit the time of each working node.

[0075] The specific implementation of the present invention is further described below with reference to specific embodiments. Specifically, it includes the following steps: loading different raw materials into different syringes and affixing labels to the syringes for easy traceability and identification; placing various syringes containing raw materials into the loading station; placing the syringes containing raw materials into the barcode reading station, where the system scans and identifies the barcodes, classifies and organizes the raw materials, and places them in specific locations; when the central control unit issues a paint preparation command, the robot places the required raw materials into the paint mixing station; the robot places empty syringes onto the electronic balance at the paint mixing station; and the paint rotary mixing mechanism quantitatively injects the required raw materials into the empty syringes. In the process, the robot places the prepared syringe into the mixing station for vacuum mixing; after mixing, the paint viscosity is tested. If the viscosity is suitable, the paint preparation is complete; if the viscosity is not suitable, mixing continues or raw materials are added and mixed again until the viscosity meets the standard. The prepared paint is then conveyed to the piston rod pressing station, and the piston rod is pressed into the syringe. The type of paint is marked on the syringe, and the sample is transferred to the scraping, spraying area or manual sample output port according to the sample preparation program instructions. The robot then places the used or empty syringe into the waste bottle collection port, completing the entire sample preparation process.
