[0002] Accurate material weighing is a key aspect of ensuring product quality and production efficiency. Especially in high-precision testing and production processes, the accuracy of material weighing directly impacts the performance and quality of the final product. Currently, common material weighing devices are typically installed on testing machines, using weighing components to measure the material. These devices are often designed to connect directly to the testing machine to enable rapid material weighing and transfer.
[0003] In existing technologies, especially during material weighing, the testing equipment inevitably vibrates due to its operating mechanism.

Detailed Implementation
[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, but does not exclude other elements or objects.
[0068] The following is in conjunction with the appendix Figure 1-7 The specific embodiments of the present invention will be further described in detail below.
[0069] Embodiments of the present invention provide a dosage dispensing device for powder or paste substances, referring to... Figure 1-5The dosage dispensing device is installed on the testing machine 100 to weigh and dispense powder or paste materials. Specifically, the dosage dispensing device includes a weighing element 200, which is spaced from the testing machine 100 to isolate the vibration of the testing machine 100. The weighing element 200 is used to receive the material and weigh it.
[0070] Understandably, by separating the weighing component 200 from the testing machine 100 to form a physical isolation, the vibrations generated by the testing machine 100 and the vibrations of the ground will not directly affect the weighing component 200. This effectively blocks the transmission path of the vibrations generated by the testing machine 100 during operation to the weighing component 200, avoids interference with the weighing process due to vibration, and improves the stability of the weighing component 200 when weighing materials.
[0071] In some embodiments, refer to Figure 2 The dosage dispensing device also includes a driving component 410, a moving component 420, a vibrating component 900, and a clamping device 500. The clamping device 500 is used to clamp the material tube 600. The driving component 410 and the moving component 420 cooperate to drive the clamping device 500 and the material tube 600 to move. The vibrating component 900 causes the material in the material tube 600 to be gradually transferred into the weighing component 200 by vibration.
[0072] For ease of understanding, the vertical direction is defined as the Z direction, the direction of movement of the drive component 410 on the testing machine 100 is defined as the X direction, and the direction perpendicular to the X direction in the horizontal direction is defined as the Y direction.
[0073] In some specific embodiments, reference is made to Figures 1 to 3 As shown, the driving member 410 is movable along the X direction and is provided on the testing machine 100, the moving member 420 is movable along the Z direction and is provided on the driving member 410, the clamping device 500 is rotatably provided on the moving member 420, and the vibration part 900 is provided on the clamping device 500.
[0074] In operation, the clamping device 500 clamps the material-loaded tube 600. The driving component 410 moves the clamping device 500 and the material tube 600 along the X direction, and the moving component 420 moves the clamping device 500 and the material tube 600 along the Y direction. The clamping device 500 rotates the material tube 600, moving it from a first preset position to a second preset position. When the material tube 600 reaches the second preset position, the vibrating component 900 vibrates the material tube 600, gradually transferring the material to the weighing component 200.
[0075] In this embodiment, a first guide rail and a first driver 810 are arranged along the X direction on the testing machine 100. A driving member 410 is disposed on the first guide rail, and the first driver 810 is connected to the driving member 410 to drive the driving member 410 to reciprocate along the X direction on the first guide rail. The driving member 410 is vertically arranged, and a second guide rail is disposed on the driving member 410. The second guide rail can be disposed on the side wall of the driving member 410 or inside the driving member 410. A moving member 420 is disposed on the second guide rail, and a second driver is connected to the moving member 420 to drive the moving member 420 to move along the Z direction on the second guide rail.
[0076] The first driver 810 and the second driver can be either a pneumatic cylinder or an electric cylinder.
[0077] It should be noted that the movement of the drive component 410, the movement of the moving component 420, and the movement of the clamping device 500 can be performed sequentially or simultaneously. There is no restriction here, as long as the material tube 600 can be rotated from the first preset position to the second preset position.
[0078] Furthermore, the feed tube 600 is vertically positioned in the first preset position to facilitate its positioning. The feed tube 600 rotates a first angle X1 towards the weighing element 200 from the first preset position to reach the second preset position, where 45° < X1 < 90°. That is, in the second preset position, the opening of the feed tube 600 is tilted upwards relative to the horizontal plane where its bottom is located, to reduce the possibility of material separating spontaneously from the feed tube 600. It is worth noting that after the feed tube 600 moves to the second preset position, its opening is positioned above the opening of the weighing element 200, so that the feed tube 600 gradually transfers the material into the weighing element 200 during vibration.
[0079] In this embodiment, a drive motor 820 is mounted on the moving part 420. A third driving wheel 821 is keyed to the shaft of the drive motor 820. A transmission wheel 822 is rotatably mounted on the moving part 420, passing through the moving part 420, and has an input end and an output end. A third driven wheel 823 is also rotatably mounted on the moving part 420, also having an input end and an output end. The output end of the third driven wheel 823 is connected to the support part 510. The input end of the third driving wheel 821 and the transmission wheel 822 are connected by a belt drive. The output end of the transmission wheel 822 and the input end of the third driven wheel 823 are connected by a belt drive. When the drive motor 820 is started, it can drive the clamping device 500 to rotate towards the weighing part 200, so that the material tube 600 rotates from a first preset position to a second preset position. In this embodiment, the first angle X1 of the rotation of the material tube 600 is 65°.
[0080] In some embodiments, refer to Figure 2 and Figure 3 The clamping device 500 includes a support part 510 and a clamping part 530; wherein, the support part 510 is rotatably disposed on the moving part 420. Specifically, the support part 510 includes a support plate 511 and a connecting plate 512. The connecting plate 512 is connected to the driven pulley, and the connection method can be adhesive, snap-fit, bolt fixing, or key connection, etc., without limitation, as long as there is no relative rotation between the two. The end face of the connecting plate 512 is parallel to that of the moving part 420. The support plate 511 and the connecting plate 512 are fixedly connected, and the support plate 511 and the connecting plate 512 are perpendicular to each other. When the connecting plate 512 rotates, it drives the support plate 511 and the connecting plate 512 to rotate synchronously.
[0081] In some embodiments, the vibrating part 900 is disposed on the support part 510. Specifically, the vibrating part 900 is disposed on the support plate 511, and its disposal method can be adhesive, snap-fit, or bolted, etc., without limitation, as long as the position of the vibrating part 900 on the support plate 511 does not shift. The clamping part 530 is disposed on the vibrating part 900. Specifically, the clamping part 530 is disposed at the end of the vibrating part 900 away from the support plate 511, and its disposal method can be adhesive, snap-fit, or bolted, etc., without limitation, as long as there is no relative displacement between the clamping part 530 and the vibrating part 900.
[0082] In this embodiment, when the clamping device 500 clamps the material tube 600 and rotates it to the second preset position, the vibration unit 900 is activated, causing the clamping device 500 and the material tube 600 to vibrate, thereby gradually transferring the material in the material tube 600 to the weighing component 200.
[0083] In some specific embodiments, the vibrating part 900 is a linear vibrator.
[0084] In some embodiments, refer to Figure 2 and Figure 3 The clamping part 530 includes a driving member 531, a first gripper 532, and a second gripper 533. The driving member 531 is located on the end face of the vibrating part 900 away from the support plate 511. More specifically, a mounting plate is provided on the end face of the vibrating part 900 away from the support plate 511. The mounting plate can be attached by bonding, snap-fitting, or bolting, etc., without limitation, as long as there is no relative movement between the two. The driving member 531, located on the mounting plate, drives the first gripper 532 and the second gripper 533 to move. The first gripper 532 and the second gripper 533 are arranged opposite each other and are both movably mounted on the driving member 531. Activation of the driving member 531 causes the first gripper 532 and the second gripper 533 to move closer or further apart. When they move closer, they can clamp the material tube 600; when they move further apart, they can release the material tube 600.
[0085] In some specific embodiments, the sidewall of the first gripper 532 facing the second gripper 533, and the sidewall of the second gripper 533 facing the first gripper 532, both have clamping surfaces for clamping the material tube 600. More specifically, each sidewall has multiple clamping surfaces with different angles, so that after the first gripper 532 and the second gripper 533 clamp the material tube 600, the sidewall of the first gripper 532 facing the second gripper 533 has multiple clamping surfaces in contact with the sidewall of the material tube 600, and the sidewall of the second gripper 533 facing the first gripper 532 has multiple clamping surfaces in contact with the sidewall of the material tube 600, thereby increasing the number of clamping points with the material tube 600 and enhancing the stability of clamping.
[0086] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 The bottom of the testing machine 100 is provided with an installation channel 110. The installation channel 110 extends through the bottom of the testing machine 100 along the thickness direction of the bottom of the testing machine 100 to facilitate the installation of the weighing component 200. The installation channel 110 creates a gap between the weighing component 200 and the testing machine 100. The gap can isolate the vibration generated by the equipment on the testing machine 100 during operation, thereby reducing the impact of the vibration generated by the testing machine 100 on the weighing component 200 and making the weighing result of the weighing component 200 more accurate.
[0087] In some embodiments, the weighing device 200 includes a weighing balance 210 and a support 300. The weighing balance 210 is mounted on the support 300 and has a weighing container for receiving materials. During weighing, the materials in the feed tube 600 are gradually transferred to the weighing container above the weighing balance 210.
[0088] In this embodiment, the weighing container and the weighing balance 210 are detachable so that the material in the weighing container can be poured out after weighing.
[0089] In some embodiments, the bracket 300 supports the weighing component 200 so that the height of the weighing component 200 is adapted to the height of the testing machine 100. Specifically, one end of the bracket 300 is located on the ground, and the other end is connected to the weighing component 200 to support it. More specifically, the connection between the bracket 300 and the weighing component 200 can be detachable or fixed; there is no limitation, as long as there is no relative movement between the weighing component 200 and the bracket 300.
[0090] In some embodiments, refer to Figure 5The support 300 includes a first support body 310, a second support body 320, and a buffer mechanism 330. The buffer mechanism 330 is located between the first support body 310 and the second support body 320, and its two ends are connected to the first support body 310 and the second support body 320 respectively to provide a buffering effect. Specifically, the bottom end of the first support body 310 is mounted on the supported object, and its top end is connected to the buffer mechanism 330. The bottom end of the second support body 320 is connected to the buffer mechanism 330, and its top end is connected to the weighing component 200.
[0091] In this embodiment, by adopting the above-described connection method, the problem of interference to the weighing balance 210 during weighing caused by vibration of the detection machine 100 and ground vibration is improved, thereby enhancing the stability of the weighing process.
[0092] In some specific embodiments, the first support 310 and the second support 320 are both columnar, which can be cylindrical or square, without limitation, with the main purpose of supporting the symmetrical component 200.
[0093] Continue to refer to Figure 5 As shown, in some embodiments, the buffer mechanism 330 includes a first connector 331, a second connector 332, and a plurality of buffer members 333. Specifically, both the first connector 331 and the second connector 332 are plate-shaped, and the plurality of buffer members 333 are evenly spaced between the first connector 331 and the second connector 332, so that there is a gap between the first connector 331 and the second connector 332, and the buffer members 333 have a certain buffering effect.
[0094] In this embodiment, the top end of the buffer 333 is connected to the bottom end of the first connector 331, and the bottom end of the buffer 333 is connected to the top end of the second connector 332. The top end of the first connector 331 is connected to the bottom end of the second support 320. The bottom end of the second connector 332 is connected to the top end of the first support 310.
[0095] In some specific embodiments, the buffer 333 is made of a flexible material.
[0096] In some more specific embodiments, the buffer 333 can be made of rubber or silicone, etc., to achieve the effect of cushioning and shock absorption.
[0097] In some embodiments, to further reduce the impact of vibration on the support 300, a plurality of buffer devices 340 are provided at the bottom of the support 300, and the buffer devices 340 also have a certain buffering effect. Specifically, the plurality of buffer devices 340 are evenly spaced around the bottom edge of the first support 310 at the bottom of the first support 310.
[0098] In this embodiment, the buffer device 340 is installed on the bottom surface so that there is a gap between the bottom of the first support 310 and the ground, so as to further reduce the influence of the vibration of the detection machine 100 and the ground vibration symmetrical measuring component 200.
[0099] In some specific embodiments, the buffer device 340 includes a mounting part and a buffer pad. The mounting part is fixed to the bottom of the first support 310 by bolts, and the buffer pad is located at the bottom of the mounting part and in contact with the ground. More specifically, the buffer pad can be made of rubber or silicone to reduce the vibration from the ground received by the mounting part and the first support 510, thereby further improving the stability of the weighing component 200 during weighing.
[0100] In some embodiments, refer to Figure 1 The dosage dispensing device also includes a protective cover 700, which is mounted on the testing machine 100 and covers the weighing component 200, the driving component 410, the moving component 420 and the clamping device 500. The protective cover 700 has a windproof effect, which can reduce the possibility of wind blowing away some materials during material transfer. At the same time, the protective cover 700 can also reduce the impact of dust on the weighing component 200.
[0101] In some specific embodiments, the protective cover 700 has a pick-and-place opening 710 on its side wall, through which the weighing component 200 can be removed or placed. The protective cover 700 also has a closing door 730, which can close the pick-and-place opening 710.
[0102] In some more specific embodiments, the opening and closing of the closed door 730 can be manually controlled or electrically controlled, for example, by an electric cylinder; these are existing technologies and will not be elaborated here, the main purpose being to enable the opening and closing of the closed door 730.
[0103] In some more specific embodiments, the top of the protective cover 700 is provided with a placement opening 720, the diameter of which is larger than the diameter of the material tube 600. The placement opening 720 extends through the top of the protective cover 700 and is used to place the material tube 600. The material tube 600 can be clamped by the clamping device 500 through the placement opening 720 for subsequent weighing.
[0104] It is worth noting that when the protective cover 700 is not installed, the movement of the drive component 410, the movement of the moving component 420, and the movement of the rotating mechanism can be performed sequentially or simultaneously. When the protective cover 700 is installed, after the material tube 600 is placed in the placement port 720, part of the material tube 600 is clamped by the clamping device 500, and the other part of the material tube 600 is placed outside the protective cover 700. Therefore, the moving component 420 needs to move downward along the Z direction first so that the material tube 600 is completely placed inside the protective cover 700. After the material tube 600 is completely placed inside the protective cover 700, the movement of the drive component 410, the movement of the moving component 420, and the movement of the rotating mechanism can be performed sequentially or simultaneously.
[0105] Embodiments of this application also disclose a dose distribution method, wherein the dose distribution method is applied to the aforementioned dose distribution device, with reference to... Figure 6 and combined Figures 1 to 5 As shown, the dose distribution method includes the following steps:
[0106] S610: The clamping device 500 is used to clamp the material-filled tube 600, so that the tube 600 is placed in the first preset position.
[0107] In this step, the material inside the feed tube 600 is pre-filled, and the feed tube 600 is set vertically in the first preset position so that the opening of the feed tube 600 faces upward.
[0108] S620: Control the drive component 410 to move along the X direction; control the moving component 420 to move along the Z direction; control the clamping device 500 to rotate, so that the material tube 600 rotates from the first preset position to the second preset position.
[0109] In this step, when the dose dispensing device is not equipped with a protective cover 700, the movement sequence of the drive component 410, the moving component 420 and the clamping device 500 can be performed sequentially or synchronously, and there is no restriction here.
[0110] When the dosage dispensing device is equipped with a protective cover 700, after the tube 600 is placed in the placement port 720, part of the tube 600 is clamped by the clamping device 500, and the other part of the tube 600 is placed outside the protective cover 700. Therefore, the moving part 420 needs to move downward along the Z direction first so that the tube 600 is completely placed inside the protective cover 700. After the tube 600 is completely placed inside the protective cover 700, the movement of the driving part 410, the movement of the moving part 420, and the movement of the rotating mechanism can be carried out sequentially or simultaneously.
[0111] In addition, when the control clamping device 500 rotates in the direction of the weighing component 200, the material tube 600 is tilted upwards in the second preset position, at which time the opening of the material tube 600 is located above the opening of the weighing component 200.
[0112] S630: Controls the vibration of the vibrating part 900 to gradually transfer the material in the material tube 600 to the weighing part 200.
[0113] In this step, when the material tube 600 is in the second preset position, the vibrating part 900 starts to vibrate, driving the material tube 600 to vibrate in the X direction, so that the material in the material tube 600 is gradually transferred to the weighing balance 210.
[0114] In some embodiments, reference Figure 7 As shown, and in combination Figures 1 to 5 As shown, the process of controlling the clamping device 500 to rotate, causing the material tube 600 to rotate from the first preset position to the second preset position, specifically includes the following steps:
[0115] 621: Control the clamping device 500 to drive the material tube 600 to rotate in the direction of the weighing piece 200.
[0116] 622: Rotate the material tube 600 from the first preset position by a first angle X1 to the second preset position. The material tube 600 is vertically positioned in the first preset position; 45° < X1 < 90°.
[0117] Specifically, in this step, the material tube 600 is controlled to rotate from the first preset position to the second angle X2 and then reach the middle position.
[0118] Start the vibrating unit 900 to break up the material in the material pipe 600.
[0119] After the control tube 600 rotates from the middle position to the third angle X3, it reaches the second preset position.
[0120] Among them, 20° < X2 < 30°; 25° < X3 < 60°.
[0121] In this embodiment, the vibration unit 900 is activated when the material tube 600 is moved to the middle position, which disperses the material in the material tube 600. For example, during the process of rotating the feed tube 600 from the first preset position to the second preset position, it first rotates 25°, reaching the middle position. At this point, the vibrating part 900 starts, driving the feed tube 600 to vibrate with a larger amplitude, for example, the vibrating part 900 drives the feed tube 600 to vibrate with an amplitude of 120μm, thereby breaking up the material inside the feed tube 600. After the material inside the feed tube 600 is broken up, the vibrating part 900 stops vibrating, and the clamping device 500 continues to drive the feed tube 600 to rotate 50°. At this point, the feed tube 600 has rotated 75°, reaching the second preset position. At the second preset position, the vibrating part 900 vibrates again, so that the material inside the feed tube 600 is gradually transferred into the weighing balance 210. At this time, the amplitude of the vibrating part 900 is smaller than the amplitude at the middle position, for example, the vibrating part 900 vibrates with an amplitude of 70μm, so that the material inside the feed tube 600 is gradually transferred into the weighing balance 210.
[0122] It is worth noting that the actual rotation angle of the material tube 600 is not limited here, but is based on the rotation angle required in the actual material transfer process.
[0123] In some embodiments, the dosage dispensing device can adapt to both small and large sample dosage applications.
[0124] For example, in situations where the sample volume is small and the accuracy requirement is high, after the material tube 600 reaches the second preset position, the vibration unit 900 is first controlled to vibrate with the first amplitude. Each vibration causes the first dose of material to be transferred from the material tube 600 to the weighing unit 200.
[0125] The vibrating unit 900 is then controlled to vibrate with a second amplitude. Each vibration causes a second dose of material to be transferred from the feed pipe 600 to the weighing unit 200. The second amplitude is smaller than the first amplitude, and the second dose is smaller than the first dose.
[0126] Specifically, in situations where the sample volume is small and high accuracy is required, taking a sample volume of 20mg as an example; during the initial stage of vibration sample addition (i.e., during the vibration at the first amplitude), the actual weight of the material added to the weighing unit 200 is scanned and read while adding the sample; when the weight of the material in the weighing unit 200 reaches the first preset weight, the vibrating unit 900 stops vibrating in advance. For example, if the first preset weight is 15mg, then when the sample reaches 15mg, the vibrating unit 900 stops vibrating. Then, the vibrating unit 900 quickly turns on or off the vibration at short intervals, for example, every 0.5s, that is, vibrating at the second amplitude, so that a small amount of material in the feed tube 600 is discharged and falls into the weighing unit 200; the action of the vibrating unit 900 quickly turning on or off the vibration is repeated, so that the sample weight gradually approaches the required weight; when the sample weight reaches and meets the requirements, the sample addition action is completed and the sample addition stops; if the last sample addition exceeds the sample addition range, the sample addition stops and an alarm is triggered.
[0127] It is worth noting that during the actual transfer process, the first amplitude, the second amplitude, the first preset weight, and the required weight can be set according to the actual situation.
[0128] In situations where the sample volume is large and the accuracy requirement is high, after the material tube 600 reaches the second preset position, the vibration unit 900 is first controlled to vibrate, so that the first dose of material is transferred from the material tube 600 to the weighing unit 200.
[0129] When the weight of the material in the weighing unit 200 is the second preset weight, the vibration unit 900 is controlled to stop vibrating.
[0130] Control the clamping device 500 to rotate, so that the material tube 600 is reset from the second preset position to the first preset position, and then rotated from the first preset position to the second preset position;
[0131] The vibration unit 900 is controlled to vibrate with a first amplitude. Each vibration causes a first dose of material to be transferred from the feed tube 600 to the weighing unit 200 until the weight of the material in the weighing unit 200 is a third preset weight.
[0132] The vibration unit 900 is controlled to vibrate with a second amplitude. Each vibration causes a second dose of material to be transferred from the feed tube 600 to the weighing unit 200, and the weight of the material in the feed tube 600 is the required weight. The second amplitude is smaller than the first amplitude, and the second dose is smaller than the first dose.
[0133] Specifically, in cases where the sample volume is large and high accuracy is required, taking a sample dosage of 1000mg as an example: During the initial stage of vibration sample addition, the weight of the actual material added to the weighing device 200 is scanned and read while adding the sample, until the weight of the material in the weighing device 200 reaches the second preset weight, for example, 950mg; at this time, the vibrating part 900 stops vibrating; the clamping device 500 drives the material tube 600 to return to the first preset position, at which point the material in the material tube 600 falls back to the bottom of the material tube 600; then the clamping device 500 controls the material tube 600 to rotate from the first preset position to the second preset position, the vibrating part 900 restarts, vibrates with the first amplitude, transfers the material into the weighing device 200, and scans and reads the weight of the actual material added to the weighing device 200 while adding the sample; when the weight of the material in the weighing device 200 reaches the third preset weight, the vibrating part 900 stops vibrating in advance. For example, if the third preset weight is 945mg, then when the weight of the material in the weighing unit 200 reaches 945mg, the vibrating unit 900 stops vibrating. Then, the vibrating unit 900 quickly turns on or off once at short intervals, for example, once every 0.5s, that is, vibrating with the second amplitude, so that a small amount of material in the material tube 600 is discharged and falls into the weighing unit 200; the action of the vibrating unit 900 quickly turning on or off the vibration is repeated, so that the sample weight gradually approaches the required weight; when the sample weight reaches and meets the requirements, the sample feeding action is completed and the sample feeding stops; if the last sample feeding exceeds the sample feeding range, the sample feeding stops and an alarm is triggered.
[0134] In the embodiments of this application, by applying the above-described dosage distribution method to a dosage distribution device to distribute materials, the stability of the weighing component is improved, and the accuracy of the weighing results is enhanced. Furthermore, the use of a step-by-step material transfer method improves the accuracy of material transfer, reduces manual intervention, and enhances the convenience and consistency of operation.

However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as set forth in the claims.
