DETAILED DESCRIPTION
[0024] In order to make the purpose, 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.
[0025] The following is combined with Figure 1-7 , the specific implementation methods of the present invention are further described in detail.
[0026] An embodiment of the present invention provides a dosage dispensing device for powder or paste-like substances, referring to Figure 1-5 , wherein the dosage dispensing device is used to be installed on the detection machine 100 to facilitate weighing and dispensing of powder or paste materials; specifically, the dosage dispensing device includes a weighing piece 200, and the weighing piece 200 is separated from the detection machine 100 by a gap, and the gap is used to isolate the vibration of the detection machine 100, and the weighing piece 200 is used to receive the material and weigh it.
[0027] It can be understood that by separating the weighing piece 200 from the detection machine 100 to form a physical isolation, the vibration generated by the detection machine 100 and the vibration of the ground will not directly affect the weighing piece 200, effectively blocking the transmission path of the vibration generated during the operation of the detection machine 100 to the weighing piece 200, avoiding the interference of vibration in the weighing process, and improving the stability of the weighing piece 200 when weighing materials.
[0028] In some embodiments, reference Figure 2 The dosage dispensing device further includes a driving member 410, a moving member 420, a vibrating unit 900, and a clamping device 500. The clamping device 500 is used to clamp the material tube 600. The driving member 410 and the moving member 420 cooperate to drive the clamping device 500 and the material tube 600 to move. The vibrating unit 900 gradually transfers the material in the material tube 600 into the weighing member 200 through vibration.
[0029] For ease of understanding, the vertical direction is defined as the Z direction, the movement direction of the driving member 410 on the inspection machine 100 is defined as the X direction, and the horizontal direction perpendicular to the X direction is defined as the Y direction.
[0030] In some specific embodiments, reference Figures 1 to 3 As shown, the driving member 410 is movably provided on the inspection platform 100 along the X direction, the moving member 420 is movably provided on the driving member 410 along the Z direction, the clamping device 500 is rotatably provided on the moving member 420 , and the vibrating part 900 is provided on the clamping device 500 .
[0031] In operation, the clamping device 500 clamps the material-laden material tube 600. The driving member 410 drives the clamping device 500 and the material tube 600 to move in the X-direction. The moving member 420 drives the clamping device 500 and the material tube 600 to move in the Y-direction. The clamping device 500 rotates the material tube 600, causing it to move from a first preset position to a second preset position. When the material tube 600 reaches the second preset position, the vibrating unit 900 vibrates the material tube 600, gradually transferring the material to the weighing member 200.
[0032] In this embodiment, a first guide rail and a first driver 810 are disposed along the X-direction on the inspection platform 100. A driving member 410 is disposed on the first guide rail. The first driver 810 is connected to the driving member 410 and is configured to drive the driving member 410 to reciprocate along the first guide rail along the X-direction. The driving member 410 is disposed vertically and is provided with a second guide rail. The second guide rail can be disposed on the side wall of the driving member 410 or can be disposed within the driving member 410. The 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 second guide rail along the Z-direction.
[0033] The first driver 810 and the second driver may be pneumatic cylinders or electric cylinders.
[0034] It should be noted that the movement of the driving member 410, the movement of the moving member 420 and the movement of the clamping device 500 can be carried out sequentially or simultaneously, and there is no limitation here, as long as the material tube 600 can be rotated from the first preset position to the second preset position.
[0035] Furthermore, the feed pipe 600 is arranged vertically in the first preset position to facilitate the positioning of the feed pipe 600. The feed pipe 600 rotates from the first preset position toward the weighing member 200 through a first angle X1 to reach the second preset position, wherein 45°<X1<90°. In other words, when the feed pipe 600 is in the second preset position, the opening of the feed pipe 600 is tilted upward relative to the horizontal plane where the bottom of the feed pipe 600 is located, so as to reduce the possibility of the material separating from the feed pipe 600 on its own. It is worth noting that after the feed pipe 600 moves to the second preset position, the opening of the feed pipe 600 is placed above the opening of the weighing member 200, so that the feed pipe 600 can gradually transfer the material into the weighing member 200 during vibration.
[0036] In this embodiment, the movable member 420 is provided with a drive motor 820, the shaft of which is keyed to a third driving wheel 821. A transmission wheel 822 is rotatably provided on the movable member 420, extending through the movable member 420 and having an input and an output. A third driven wheel 823 is also rotatably provided on the movable member 420, which also has an input and an output. The output end of the third driven wheel 823 is connected to the support portion 510. The third driving wheel 821 is connected to the input end of the transmission wheel 822 via a pulley transmission. The output end of the transmission wheel 822 is connected to the input end of the third driven wheel 823 via a pulley transmission. When the drive motor 820 is activated, it drives the clamping device 500 to rotate toward the weighing member 200, thereby rotating the feed pipe 600 from the first preset position to the second preset position. The first angle X1 of rotation of the feed pipe 600 in this embodiment is 65°.
[0037] In some embodiments, reference Figure 2 and Figure 3 The clamping device 500 includes a support portion 510 and a clamping portion 530; wherein the support portion 510 is rotatably provided on the movable member 420. Specifically, the support portion 510 includes a support plate 511 and a connecting plate 512, and the connecting plate 512 is connected to the driven pulley. The connection method can be bonding, clamping, bolt fixing or key connection, etc., which is not limited here, and the main principle is that no relative rotation occurs between the two. The connecting plate 512 is parallel to the end face of the movable member 420, and the support plate 511 is fixedly connected to the connecting plate 512. At the same time, 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.
[0038] In some embodiments, the vibration part 900 is provided on the support part 510. Specifically, the vibration part 900 is provided on the support plate 511. The installation method thereof can be adhesive, clamping, or bolting, etc., which is not limited here, and the main purpose is that the position of the vibration part 900 on the support plate 511 does not shift. The clamping part 530 is provided on the vibration part 900. Specifically, the clamping part 530 is provided at the end of the vibration part 900 away from the support plate 511. The installation method thereof can be adhesive, clamping, or bolting, etc., which is not limited here, and the main purpose is that there is no relative displacement between the clamping part 530 and the vibration part 900.
[0039] In this embodiment, when the clamping device 500 clamps the material tube 600 and rotates to the second preset position, the vibration part 900 is activated, driving the clamping device 500 and the material tube 600 to vibrate, thereby gradually transferring the material in the material tube 600 to the weighing piece 200.
[0040] In some specific embodiments, the vibration part 900 is a linear vibrator.
[0041] In some embodiments, reference Figure 2 and Figure 3 The clamping part 530 includes a driving member 531, a first clamping jaw 532 and a second clamping jaw 533. The driving member 531 is provided on the end surface of the vibrating part 900 away from the support plate 511. More specifically, a mounting plate is provided on the end surface of the vibrating part 900 away from the support plate 511. The mounting plate can be provided by bonding, clamping or bolting, etc., which is not limited here, and the main thing is that there will be no relative movement between the two. The driving member 531 is provided on the mounting plate and is used to drive the first clamping jaw 532 and the second clamping jaw 533 to move. The first clamping jaw 532 and the second clamping jaw 533 are arranged opposite to each other, and both are movably provided on the driving member 531. When the driving member 531 is activated, it can drive the first clamping jaw 532 and the second clamping jaw 533 to move closer to or farther away from each other. When the two are close to each other, they can clamp the material pipe 600; when the two are farther away from each other, they can release the material pipe 600.
[0042] In some specific embodiments, the side wall of the first clamping jaw 532 facing the second clamping jaw 533 and the side wall of the second clamping jaw 533 facing the first clamping jaw 532 both have clamping surfaces for clamping the material tube 600. More specifically, multiple clamping surfaces are provided on each side wall, and the multiple clamping surfaces have different angles. When the first clamping jaw 532 and the second clamping jaw 533 clamp the material tube 600, multiple clamping surfaces on the side wall of the first clamping jaw 532 facing the second clamping jaw 533 contact the side wall of the material tube 600, and multiple clamping surfaces on the side wall of the second clamping jaw 533 facing the first clamping jaw 532 contact the side wall of the material tube 600. This increases the number of clamping points on the material tube 600, thereby enhancing the stability of the clamping.
[0043] In some embodiments, reference Figure 1 、 Figure 2 and Figure 4 A mounting channel 110 is provided at the bottom of the detection machine 100. The mounting channel 110 penetrates the bottom of the detection machine 100 along the thickness direction of the bottom of the detection machine 100 to facilitate the installation of the weighing piece 200. The mounting channel 110 creates a gap between the weighing piece 200 and the detection machine 100. The gap can isolate the vibration generated by the equipment on the detection machine 100 during operation, thereby reducing the impact of the vibration generated by the detection machine 100 on the weighing piece 200, making the weighing result of the weighing piece 200 more accurate.
[0044] In some embodiments, the weighing member 200 includes a weighing scale 210 and a support 300. The weighing scale 210 is mounted on the support 300. The weighing scale 210 has a weighing container for receiving materials. During weighing, the material in the material tube 600 is gradually transferred to the weighing container above the weighing scale 210.
[0045] In this embodiment, the weighing container and the weighing balance 210 are detachably arranged to facilitate pouring out the material in the weighing container after weighing.
[0046] In some embodiments, the bracket 300 is used to support the weighing member 200 so that the height of the weighing member 200 is adapted to the height of the testing machine 100. Specifically, one end of the bracket 300 is disposed on the ground, and the other end is connected to the weighing member 200 to support the weighing member 200. More specifically, the bracket 300 and the weighing member 200 can be detachably connected or fixedly connected, without limitation herein, provided that the weighing member 200 and the bracket 300 do not move relative to each other.
[0047] In some embodiments, reference Figure 5 The bracket 300 includes a first support body 310, a second support body 320, and a buffer mechanism 330. The buffer mechanism 330 is disposed between the first support body 310 and the second support body 320.

The placement opening 720 penetrates 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.
[0061] It is worth noting that when the protective cover 700 is not set, the movement of the driving member 410, the movement of the moving member 420 and the movement of the rotating mechanism can be carried out in sequence or simultaneously; when the protective cover 700 is set, 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, so the moving member 420 needs to move downward along the Z direction first so that the material tube 600 is completely placed in the protective cover 700; when the material tube 600 is completely placed in the protective cover 700, the movement of the driving member 410, the movement of the moving member 420 and the movement of the rotating mechanism can be carried out in sequence or simultaneously.
[0062] The embodiment of the present application further discloses a dosage dispensing method, wherein the dosage dispensing method is applied to the above-mentioned dosage dispensing device, referring to Figure 6 , and combined with Figures 1 to 5 As shown, the dosage dispensing method includes the following steps: S610: Using the clamping device 500 to clamp the material tube 600 filled with material, the material tube 600 is placed in a first preset position.
[0063] In this step, the material in the material tube 600 is filled in advance, and the material tube 600 is vertically arranged at the first preset position so that the opening of the material tube 600 faces upward.
[0064] S620: Control the driving member 410 to move along the X direction; control the moving member 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.
[0065] In this step, when the dosage dispensing device is not provided with a protective cover 700, the movement sequence of the driving member 410, the moving member 420 and the clamping device 500 can be performed sequentially or synchronously, which is not limited here.
[0066] When the dosage dispensing device is provided with a protective cover 700, 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 movable member 420 needs to move downward along the Z direction first so that the material tube 600 is completely placed in the protective cover 700; when the material tube 600 is completely placed in the protective cover 700, the movement of the driving member 410, the movement of the movable member 420 and the movement of the rotating mechanism can be carried out in sequence or simultaneously.
[0067] In addition, the clamping device 500 is controlled to rotate toward the direction where the weighing piece 200 is located, so that the material tube 600 is tilted upward at the second preset position. At this time, the opening of the material tube 600 is located above the opening of the weighing piece 200.
[0068] S630 : Control the vibration part 900 to vibrate, and gradually transfer the material in the material tube 600 to the weighing piece 200 .
[0069] In this step, when the material tube 600 is at the second preset position, the vibration unit 900 starts to vibrate, driving the material tube 600 to vibrate along the X direction, so that the material in the material tube 600 is gradually transferred to the weighing balance 210 .
[0070] In some embodiments, reference Figure 7 As shown, combined with Figures 1 to 5 As shown, in the process of controlling the rotation of the clamping device 500 to rotate the material tube 600 from the first preset position to the second preset position, the following steps are specifically included: 621: Control the clamping device 500 to drive the material tube 600 to rotate toward the weighing piece 200.
[0071] 622: Rotate the material tube 600 from the first preset position to the second preset position through the first angle X1, wherein the material tube 600 is vertically positioned at the first preset position; 45°<X1<90°.
[0072] Specifically, in this step, the material pipe 600 is controlled to rotate from the first preset position to the second angle X2 and then reach the middle position.
[0073] The vibration part 900 is started to break up the material in the material tube 600 .
[0074] The material pipe 600 is controlled to rotate from the middle position to a third angle X3 and then reach a second preset position.
[0075] Among them, 20°<X2<30°; 25°<X3<60°.
[0076] In this embodiment, the vibration part 900 is activated when the material tube 600 is transferred to the middle position to break up the material in the material tube 600 . For example, when the material pipe 600 rotates from the first preset position to the second preset position, it first rotates 25°. At this time, it reaches the middle position. The vibration part 900 starts and drives the material pipe 600 to vibrate with a larger amplitude. For example, the vibration part 900 drives the material pipe 600 to vibrate with an amplitude of 120μm, thereby breaking up the material in the material pipe 600; after the material in the material pipe 600 is broken up, the vibration part 900 stops vibrating, and the clamping device 500 continues to drive the material pipe 600 to rotate 50°. At this time, the material pipe 600 has rotated 75° and reaches the second preset position; at the second preset position, the vibration part 900 vibrates again to gradually transfer the material in the material pipe 600 to the weighing balance 210. At this time, the amplitude of the vibration part 900 is smaller than the amplitude at the middle position. For example, the vibration part 900 vibrates with an amplitude of 70μm to gradually transfer the material in the material pipe 600 to the weighing balance 210.
[0077] It is worth noting that the actual rotation angle of the material tube 600 is not limited here, and is mainly based on the rotation angle required during the actual material transfer process.
[0078] In some embodiments, the dosage dispensing device can adapt to occasions where a small amount of sample is added and occasions where a large amount of sample is added.
[0079] For example, in situations where the sample volume is small and the precision requirement is high, when the material tube 600 reaches the second preset position, the vibration part 900 is first controlled to vibrate at the first amplitude, and each vibration transfers the first dose of material from the material tube 600 to the weighing piece 200.
[0080] The vibrating part 900 is then controlled to vibrate at a second amplitude, and each vibration transfers a second dose of material from the material tube 600 to the weighing member 200; wherein the second amplitude is smaller than the first amplitude, and the second dose is smaller than the first dose.
[0081] Specifically, in applications where the sample volume is small and high precision is required, for example, a sample volume of 20 mg is added. During the initial stage of vibratory sample addition (i.e., during vibration at the first amplitude), the actual weight of the material added to the weighing member 200 is scanned and read. When the weight of the material in the weighing member 200 reaches a first preset weight, the vibrating unit 900 prematurely stops vibrating. For example, if the first preset weight is 15 mg, the vibrating unit 900 stops vibrating when the sample reaches 15 mg. The vibrating unit 900 then rapidly turns on and off vibration at short intervals, for example, every 0.5 seconds, vibrating at the second amplitude, causing a small amount of material in the feed tube 600 to be discharged and fall into the weighing member 200. This rapid on and off vibration of the vibrating unit 900 is repeated, gradually approaching the required weight. When the sample weight reaches and meets the required weight, the sample addition process is completed and the sample addition process stops. If the last sample addition exceeds the sample addition range, the sample addition process stops and an alarm is triggered.
[0082] 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 actual conditions.
[0083] In situations where the amount of material added is large and the precision requirement is high, when the material tube 600 reaches the second preset position, the vibration part 900 is first controlled to vibrate to transfer the first dose of material from the material tube 600 to the weighing member 200; When the weight of the material in the weighing member 200 reaches a second preset weight, the vibration unit 900 is controlled to stop vibrating; Controlling the rotation of the clamping device 500 to reset the material tube 600 from the second preset position to the first preset position, and then rotating from the first preset position to the second preset position; Controlling the vibration unit 900 to vibrate at a first amplitude, transferring a first dose of material from the material tube 600 to the weighing member 200 with each vibration, until the weight of the material in the weighing member 200 reaches a third preset weight; The vibration part 900 is controlled to vibrate at a second amplitude. Each vibration transfers a second dose of material from the material tube 600 to the weighing piece 200 until the weight of the material in the material 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.
[0084] Specifically, in situations where the sample addition amount is large and the precision requirement is high, the sample addition amount is 1000 mg as an example; in the early stage of vibration sample addition, the weight value of the material actually added to the weighing piece 200 is scanned and read while adding the sample, until the weight of the material in the weighing piece 200 reaches the second preset weight, for example, it reaches 950 mg; at this time, the vibration part 900 stops vibrating; the clamping device 500 drives the material pipe 600 to reset to the first preset position, at which time the material in the material pipe 600 falls back to the bottom of the material pipe 600; then the clamping device 500 controls the material pipe 600 to rotate from the first preset position to the second preset position, and the vibration part 900 restarts and vibrates with the first amplitude to transfer the material into the weighing piece 200, and scans and reads the weight value of the material actually added to the weighing piece 200 while adding the sample; when the weight of the material in the weighing piece 200 reaches the third preset weight, the vibration part 900 stops vibrating in advance. For example, if the third preset weight is 945 mg, then when the weight of the material in the weighing member 200 reaches 945 mg, the vibration unit 900 stops vibrating. The vibration unit 900 then rapidly turns on and off vibration at short intervals, for example, every 0.5 seconds, vibrating at the second amplitude, causing a small amount of material in the material tube 600 to be discharged and fall into the weighing member 200. This rapid on and off vibration of the vibration unit 900 is repeated until the added weight gradually approaches the required weight. When the added weight reaches and meets the required weight, the addition process is complete and the addition process stops. If the last added weight exceeds the addition range, the addition process stops and an alarm is issued.
[0085] In the embodiments of the present application, the aforementioned dosage dispensing method is applied to a dosage dispensing device to distribute material, thereby improving the stability of the weighing device and the accuracy of the weighing results. Furthermore, the gradual transfer of material improves the accuracy of material transfer, reduces manual intervention, and improves the convenience and consistency of operation.

However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as set forth in the claims. Furthermore, the invention described herein is susceptible to other embodiments and may be practiced or implemented in a variety of ways.
