[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] The following is combined with Figures 1-2 The present invention describes an automatic testing device for media content, comprising an environmental chamber 100, a weighing and processing device 200, and a sample handling device 300. The environmental chamber 100 is provided with an openable or closable chamber 110 for containing and processing samples. The weighing and processing device 200 is located on one side of the environmental chamber 100 and is used for weighing samples and processing data. The sample handling device 300 is configured to transfer samples between the environmental chamber 100 and the weighing and processing device 200, and includes a gripping unit 320 for picking up and placing samples.

[0041] The gripping unit 320 is configured to move toward or away from the location of at least one of the environmental chamber 100 and the weighing processing device 200, and the gripping unit 320 can extend into or move away from the chamber 110.

[0042] The automatic medium content testing equipment provided by this utility model consists of an environmental chamber 100, a weighing and processing device 200, and a sample taking and placing device 300. The sample taking and placing device 300 transfers the sample between the environmental chamber 100 and the weighing and processing device 200. The gripping unit 320 can perform the releasing or gripping preparation action of the sample or the workpiece carrying the sample. The movement of the gripping unit 320 realizes the back-and-forth gripping of the sample between the chamber 110 and the weighing and processing device 200, thereby reducing the cycle time of the entire gripping and placing process, realizing automated operation, which can greatly improve the testing efficiency and free the testing personnel from tedious solid content testing. By replacing manual operation with the above equipment, the time that the testing personnel are in contact with the coating can be reduced, protecting the health of the testing personnel. The structure is clear and easy to maintain, improving the accuracy of the test.

[0043] It should be noted that the environmental chamber 100 can control temperature and humidity, with the temperature controllable from 0℃ to 200℃ and the humidity controllable from 10% to 90%; temperature and humidity can be adjusted through the control system. Understandably, depending on the sample medium, the testing temperature for water-based coatings is 105℃, and they should be placed in the oven immediately after the first weighing; the testing temperature for solvent-based and reactive coatings is 120℃, and they need to be placed in a standard environment of (23±2)℃ and (50±10)% for 24 hours after the first weighing before being placed in the environmental chamber 100 for testing.

[0044] It should also be noted that in some examples of this utility model, the device is not limited to testing coating samples. Depending on the sample medium, the moisture content, volatile content, etc. of powder samples can also be detected.

[0045] Specifically, refer to Figure 2 In some examples, the environmental enclosure 100 includes a enclosure 120 and a door 130. The enclosure 120 has an opening. The door 130 is movably connected to the opening of the enclosure 120 and cooperates with the interior of the enclosure 120 to form a chamber 110. The enclosure 120 is provided with a drive unit, the output of which is connected to the door 130 to drive the door 130 to move to open or close the opening of the enclosure 120.

[0046] Through an advanced and precise control system, efficient interaction between the drive unit and the sampling device 300 is achieved. Specifically, when the gripping unit 320 of the sampling device 300 performs the task of placing or removing samples from the chamber 110, the entire process exhibits a high degree of intelligence and coordination. At this time, the control system precisely controls the drive unit to start operating according to preset programs and instructions. After receiving the control signal, the drive unit responds quickly, and its output power causes the related mechanical structures connected to it to produce corresponding actions, thereby driving the door 130 to open smoothly and accurately.

[0047] Specifically, in some examples, the door 130 is movably connected to the housing 120, and the drive unit can be an electric push rod, a telescopic cylinder, etc., to drive the door 130 to move relative to the housing 120; of course, in other examples, the door 130 can also be rotatably connected to the housing 120, which is not limited here.

[0048] When the gripping unit 320 of the sampling device 300 needs to extend into the chamber 110, the control system can control the movement of the drive unit to open the door 130, and then the gripping unit 320 can place or remove the sample into or from the chamber 110.

[0049] Understandably, referring to Figure 1 and Figure 2 In some examples of this utility model, the sampling device 300 further includes a transfer body 310, a first driving mechanism 330, and a second driving mechanism 340. The transfer body 310 is configured to move toward or away from at least one of the environmental chamber 100 and the weighing processing device 200. A gripping unit 320 is movably disposed on the transfer body 310. The output end of the first driving mechanism 330 is fixedly connected to the transfer body 310 to drive the transfer body 310 to move. The second driving mechanism 340 is disposed on the transfer body 310, and its output end is fixedly connected to the gripping unit 320 to drive the gripping unit 320 to move. Specifically, in this embodiment, the transfer body 310 can reciprocate in the left-right direction driven by the first driving mechanism 330, while the gripping unit 320 can reciprocate in the front-back direction driven by the second driving mechanism 340.

[0050] With the above configuration, since the transfer body 310 and the gripping unit 320 are driven by different drive mechanisms, parallel operation or rapid switching actions can be achieved. For example, while the transfer body 310 moves to the target position, the gripping unit 320 can perform the workpiece release or clamping preparation action, thereby reducing the cycle time of the entire gripping and placement process and improving production efficiency. The mobility of the transfer body 310 allows the entire sampling device 300 to cover a larger working area, realizing the back-and-forth gripping of workpieces between the chamber 110 and the weighing and processing device 200, increasing the applicability and flexibility of the device. Furthermore, through the first drive mechanism 330 and the second drive mechanism 340, operational errors are reduced, the accuracy and reliability of operation are improved, and an automated process is achieved.

[0051] In some examples, both the environmental chamber 100 and the weighing processing device 200 are positioned away from the starting position of the transfer body 310. In such cases, the transfer body 310 is configured to move toward or away from either the environmental chamber 100 or the weighing processing device 200. Conversely, in other examples, one of the environmental chamber 100 and the weighing processing device 200 is positioned away from the starting position of the transfer body 310, while the other is positioned close to it. Therefore, when the transfer body 310 is configured to move toward or away from the environmental chamber 100, it also moves toward or away from the weighing processing device 200. For example, if the transfer body 310 moves toward the environmental chamber 100, it moves away from the weighing processing device 200.

[0052] Understandably, referring to Figure 2 In some examples of this utility model, the box 120 is provided with a plurality of shelves 121, which are arranged at intervals along the height direction of the box 120.

[0053] Multiple shelves 121 cleverly divide the space within the enclosure 120 into multiple layers along the vertical direction, successfully achieving layered storage and greatly improving space utilization efficiency. This allows for the maximum storage of various samples within the limited volume of the enclosure 120. Furthermore, depending on the specific needs, different samples can be placed systematically on their corresponding shelves 121. In this way, when a specific sample needs to be located or retrieved, testing personnel can quickly and accurately locate the shelf 121 containing the target sample, significantly reducing the time required for retrieval and making the entire process convenient and efficient.

[0054] In the embodiments of this utility model, the number of shelves 121 is three. Of course, the number of shelves 121 is not limited here, and can also be one, two, four, etc.

[0055] Reference Figure 2 In some examples, each shelf 121 is provided with multiple positioning slots 1211 at intervals. The multiple positioning slots 1211 are used to accommodate and position the sample, thereby improving the stability of the sample when it is placed.

[0056] In a specific example, shelf 121 is divided into multiple columns and multiple layers, which can be numbered, such as column A, column B, column C, layer 1, layer 2, layer 3, etc. The final sample placement position can be, for example, column A, layer 1, abbreviated as A1.

[0057] Understandably, referring to Figure 1 and Figure 2In some examples, the transfer body 310 also includes a movable base 311 and a third drive mechanism 312. The movable base 311 is fixedly connected to the output end of the first drive mechanism 330. The third drive mechanism 312 is mounted on the movable base 311. The gripping unit 320 and the second drive mechanism 340 are both mounted on the output end of the third drive mechanism 312. The third drive mechanism 312 is used to drive the gripping unit 320 and the second drive mechanism 340 to move up and down along the height direction of the environmental box 100.

[0058] Through the above-described configuration, the third drive mechanism 312 can precisely control the movement trajectory and position of the gripping unit 320 according to a preset program or instruction. This ensures that when placing a sample at the corresponding shelf 121 position, the sample can be accurately placed on the predetermined shelf 121 layer and position, avoiding incorrect sample placement or collision with other items. Similarly, when gripping a sample, the target sample can be accurately located, improving operational accuracy, achieving automated operation, reducing reliance on manual operation, and thus reducing operational errors caused by human factors (such as fatigue, negligence, etc.). In addition, the automated operation of the third drive mechanism 312 can also prevent testing personnel from directly contacting the sample, thereby reducing the risk of injury to testing personnel.

[0059] Reference Figure 1 and Figure 2 In some examples of this utility model, the environmental chamber 100 and the weighing and processing device 200 are located on opposite sides of the sampling device 300, that is, the environmental chamber 100 is located on the front side of the sampling device 300, and the weighing and processing device 200 is located on the rear side of the sampling device 300.

[0060] The above-described layout on both sides helps to create a relatively stable operating environment. When the sample handling device 300 transfers samples in the middle, it will not be subject to excessive interference from other directions, which is conducive to precise control of the grasping and transfer actions, thereby improving the accuracy of weighing. In addition, it can also avoid mutual interference between the environmental chamber 100 and the weighing and processing device 200 to a certain extent, and the functional zoning of the environmental chamber 100 and the weighing and processing device 200 is more clearly defined, which facilitates independent maintenance, repair and calibration of each.

[0061] Of course, in other examples, the environmental chamber 100 and the weighing processing device 200 are arranged on the same side, which is not limited here.

[0062] Understandably, referring to Figure 1 and Figure 2In some examples, the transfer body 310 also includes a fourth drive mechanism 313, which is located between the movable seat 311 and the third drive mechanism 312. The third drive mechanism 312 is mounted on the output end of the fourth drive mechanism 313, and the fourth drive mechanism 313 is used to drive the third drive mechanism 312 to rotate circumferentially.

[0063] With the above settings, the fourth drive mechanism 313 can drive the third drive mechanism 312 to rotate flexibly. The rotation angle is not limited. It can achieve 360-degree omnidirectional rotation, or rotate at specific angles such as 50 degrees or 200 degrees.

[0064] When the third drive mechanism 312 rotates, it synchronously drives the gripping unit 320 and the second drive mechanism 340 to rotate as well. This design brings several significant benefits: it not only enables the clamping components to accurately adapt to the different set positions of the environmental chamber 100 and the weighing and processing device 200, easily handling various complex installation layouts and operational requirements, but also allows the device to adapt effortlessly to different postures or positions of the environmental chamber 100 and the weighing and processing device 200 due to factors such as site and process in different working scenarios, greatly improving environmental adaptability. The good coordination of the rotation of each component reduces problems such as shaking and collision caused by positional deviation, making the operation more stable and accurate, and improving the overall reliability of the sampling and placement device 300.

[0065] Understandably, referring to Figure 2 In some examples of this utility model, the sampling device 300 includes a first track 350, which is movably connected to the transfer body 310; wherein the arrangement direction of the first track 350 is consistent with the length direction of the environmental box 100.

[0066] Specifically, refer to Figure 2 This can be understood as follows: the first track 350 includes two guide rails spaced apart, and the bottom of the transfer body 310 is provided with two sliding seats, which correspond one-to-one with the two guide rails and are slidably connected; the guide rails are parallel to the length direction of the environmental box 100, so that the first drive mechanism 330 can drive the transfer body 310 to move to a position close to the environmental box 100 and the weighing processing device 200, further improving the stability of the transfer body 310 when it moves.

[0067] Of course, in some other examples, the first track 350 described above may also intersect with the length direction of the environmental chamber 100.

[0068] Reference Figure 1 and Figure 2In some examples of this utility model, the transfer body 310 is provided with a second track 360, and the gripping unit 320 is movably connected to the second track 360; wherein, the arrangement direction of the second track 360 is consistent with the width direction of the environmental box 100.

[0069] Specifically, refer to Figure 2 This can be understood as follows: the second track 360 is perpendicular to the length direction of the environmental box 100, so that the second drive mechanism 340 can drive the gripping unit 320 to perform telescopic translational movements toward the position of the environmental box 100 or the weighing processing device 200, thereby further improving the stability of the transfer body 310 when it moves.

[0070] Of course, in some other examples, the second track 360 described above may also be tilted relative to the length direction of the environmental chamber 100.

[0071] Understandably, referring to Figure 1 and Figure 2 In some examples of this utility model, the gripping unit 320 includes two parallel grippers 321 and a driving member 322. The driving member 322 drives the two grippers 321 to move towards or away from each other, thereby achieving the gripping of an object. The driving member 322 can be a motor, a cylinder, or a hydraulic cylinder, etc. Of course, in another example, the gripping unit 320 may also include multiple independently controllable fingers. Each finger can move flexibly and can achieve complex gripping actions, such as pinching, wrapping, etc., which are not limited here.

[0072] Reference Figure 2 In some examples, the second track 360 includes a base and two guide channels spaced apart on the base. A mounting plate 370 and two guide posts 380 are provided between the gripping unit 320 and the second track 360. The two guide posts 380 correspond one-to-one with the two guide channels and are slidably inserted and engaged. One end of the mounting plate 370 is fixedly connected to the drive member 322 of the gripping unit 320, and the other end is connected to the two guide posts 380. The second drive mechanism 340 is mounted on the base, and the output end of the second drive mechanism 340 passes through the base and is connected to the mounting plate 370.

[0073] With the above configuration, the second drive mechanism 340 drives the mounting plate 370 to slide the guide column 380, thereby driving the gripping unit 320 to extend and retract. This not only results in a simple and clear structure but also high stability.

[0074] It should be noted that, referring to Figure 2In some examples of this utility model, the first drive mechanism 330, the second drive mechanism 340 and the third drive mechanism 312 can all be electric push rods, telescopic cylinders, etc., and are not limited here; in addition, the fourth drive mechanism 313 can be a motor drive mechanism or a pneumatic motor mechanism, etc., and are not limited here.

[0075] It should also be noted that in some examples of this utility model, the weighing processing device 200 includes a balance and a data processing chip disposed within the balance, thereby enabling the weighing, data storage, calculation, and retrieval of samples.

[0076] Taking polyurethane samples as an example, the testing process of this utility model is as follows:

[0077] Step 1: Zero the weighing device 200, manually place the aluminum foil dish on the weighing device 200, and obtain the mass M0; pour about 10g of polyurethane sample into the aluminum foil dish and weigh it to obtain M1; take the aluminum foil dish away from the gripping unit 320 of the sampling device 300 and place it in the chamber 110A1 of the environmental chamber 100.

[0078] Step 2: The environmental chamber 100 automatically processes the sample, first maintaining it at 23℃ and 50% humidity for 24 hours, then raising the temperature to 120℃ and maintaining it for 3 hours; then cooling it down to 23℃ and maintaining it at 10% humidity for 2 hours. The sampling device 300 uses its gripping unit 320 to remove the sample from point A1 onto the weighing device 200, and weighs it to obtain M2. After weighing, the data is automatically saved, and the sample is automatically returned to point A1 via the gripping unit 320 of the sampling device 300.

[0079] The solid content is calculated as follows: Solid content = (M2-M0) / (M1-M0)*100%.

[0080] Understandably, one device can perform multiple sets of similar solid content tests simultaneously. After the tests are completed according to the above steps, the testing personnel can go to the weighing and processing device 200 to review the test data, record it, and process the tested samples.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
