Description

Technical Field

[0001] This utility model relates to the field of sample addition technology, specifically to a multi-channel solid sampler. Background Technology

[0002] The sample dispenser is used for high-precision automatic dispensing of solid powder raw materials. It dispenses powder through the interaction between a drive component and a powder container. For dispensing multiple solid powders, multiple powder containers are typically required, making the ease of container loading and unloading by the drive component crucial. Current technology incorporates a powder container storage rack within the dispenser, with a feeding mechanism controlling the movement of the dispensing mechanism between the dispensing station and the rack, allowing the drive component to load and unload powder containers. However, after dispensing one type of solid powder, existing dispensers require manual disassembly and replacement of the powder container, a cumbersome process that reduces efficiency. Furthermore, due to the structural limitations of the powder container storage rack, current dispensers necessitate the use of a multi-axis robotic arm to store and remove powder containers, complicating the dispenser's overall structure. Utility Model Content

[0003] This invention provides a multi-channel solid sampler.

[0004] Specifically, this utility model is achieved through the following technical solution:

[0005] This utility model provides a multi-channel solid sampler, comprising:

[0006] The sample dispensing mechanism is equipped with a drive component and a powder tank, and the drive component and the powder tank are detachably connected;

[0007] The powder bucket storage rack is equipped with multiple powder bucket storage slots, with each slot corresponding to one powder bucket.

[0008] A container storage rack is provided with at least one container storage space;

[0009] The feeding mechanism is located on the top of the sample dispenser and is connected to the sample dispensing mechanism, thereby enabling the sample dispensing mechanism to move freely between the powder bucket storage position and the container storage position.

[0010] In some embodiments, the feeding mechanism can drive the sample feeding mechanism to feed along a first direction, a second direction, and a third direction that are mutually orthogonal.

[0011] In some embodiments, the powder bucket storage rack includes a frame with a plurality of notches corresponding one-to-one with powder bucket storage positions. The frame has grooves formed on both sides of the notches, and the grooves have openings at the open ends of the notches, so that the edge of the powder bucket can be inserted into the groove through the opening, thereby storing the powder bucket in the notch.

[0012] In some embodiments, the powder bucket storage rack further includes a clamping assembly, which is provided with a locking block and an elastic element. The locking block is disposed within the groove and located at the opening. The elastic element is elastically connected to the locking block to be adapted to open the opening by overcoming the elastic force of the locking block, and to block the opening by releasing the elastic force.

[0013] In some embodiments, the card block is provided with a blocking portion near the opening and a supporting portion away from the opening. When the card block blocks the opening by releasing elastic force, the edge is clamped between the supporting portion and the top wall of the groove.

[0014] In some embodiments, the clamping assembly is provided with a bracket and a guide post, the bracket being connected to the frame below the notch via the guide post, and the surface of the bracket being provided with a rubber pad.

[0015] In some embodiments, the guide post extends into the groove to guide the locking block to move between positions where the opening is open and where the opening is closed.

[0016] In some embodiments, the locking block is sloped toward the opening direction to allow the edge to overcome elastic force and open the opening by squeezing the slope during the process of the powder bucket being pushed into the trough; and / or, the locking block is sloped away from the opening direction to allow the edge to overcome elastic force and open the opening by squeezing the slope during the process of the powder bucket being pulled out of the trough.

[0017] In some embodiments, the sample dispenser further includes a powder receiving mechanism, which is provided with a movable tray adapted to move away from the powder outlet of the powder container when the powder container is performing a sample dispensing operation, and to move below the powder outlet of the powder container when the powder container is performing a non-sample dispensing operation.

[0018] In some embodiments, the sample dispenser further includes an antistatic module, a drying module, and a weighing module, wherein the weighing module is disposed on a container storage rack.

[0019] According to this utility model, by setting the drive component and the powder bucket to be connected by magnetic attraction, the loading and unloading process between the drive component and the powder bucket is quick. With the powder bucket storage rack with multiple powder bucket storage positions, the feeding mechanism is used to send the sample dispensing mechanism to the corresponding powder bucket storage position, and the unloading and storage of the powder bucket can be completed in one go. The loading of new powder buckets can also be completed quickly, which greatly improves the operating efficiency of the sample dispensing process for various powder raw materials and simplifies the structure of the sample dispensing instrument.

[0032] This disclosure will now be discussed with reference to several embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement this disclosure, and are not intended to imply any limitation on the scope of this disclosure.

Other explicit and implicit definitions may also be included below.

[0034] Specific numerical values ​​or ranges may be referred to in the following description. It should be understood that these values ​​and ranges are merely exemplary and may be helpful in putting the ideas of this disclosure into practice. However, the description of these examples is not intended to limit the scope of this disclosure in any way. These values ​​or ranges may be set differently depending on the specific application scenario and requirements.

[0035] As mentioned above, existing sample dispensers are cumbersome to operate and have low efficiency when handling various solid powders, and the use of multi-axis robotic arms leads to structural complexity. The multi-channel solid sample dispenser proposed in this invention at least partially solves the above problems. Figure 1 As shown, the multi-channel solid sampler of this utility model embodiment generally includes a sample dispensing mechanism 10, a powder bucket storage rack 20, a container storage rack 30, a feeding mechanism, an anti-static module, a drying module, a weighing module, and several powder buckets 12. Several powder buckets 12 are placed on the powder bucket storage rack 20. Each powder bucket 12 contains different types of solid powder. The feeding mechanism drives the sample dispensing mechanism 10 to move freely along the first direction x, the second direction y, and the third direction z, thereby controlling the sample dispensing mechanism 10 to dispense samples to the containers on the container storage rack 30 below, and controlling the sample dispensing mechanism 10 to move to the powder bucket storage rack 20 to pick up or replace powder buckets 12 of different types of solid powder.

[0036] In one embodiment, the sample dispensing mechanism 10 consists of a drive assembly 11 and a powder bucket 12. The drive assembly 11 and the powder bucket 12 are connected by magnetic attraction to achieve quick and detachable connection, thereby cooperating with the powder bucket storage rack to realize the quick loading and unloading of the powder bucket.

[0037] In one embodiment, the container storage rack has multiple container storage positions, facilitating the feeding mechanism to align the powder bucket with containers in different storage positions for sample addition. In another embodiment, a weighing module is installed on the container storage rack to accurately detect the sample addition amount.

[0038] The powder bucket storage rack 20 includes a frame 21 and a clamping assembly. The frame 21 is used to support the clamping assembly and the powder bucket 12. The clamping assembly works with the frame 21 to clamp the powder bucket 12 in the placement position of the frame 21.

[0039] In one embodiment, such as Figure 1 and 3 As shown, the frame 21 has 5 notches. In another embodiment, the number of notches on the frame 21 can be one or other numbers. Each notch corresponds to storing one powder bucket 12. That is to say, the number of powder buckets 12 that can be stored at the same time will vary.

[0040] In one embodiment, the notch is formed in a "U" shape, that is, one end of the notch is an open opening 23 and the other end is closed. In another embodiment, both ends of the notch can be open openings 23. In this case, the powder bucket 12 can be inserted or removed from either end of the opening 23, making the operation more convenient.

[0041] In one embodiment, a pair of opposing grooves 22 are formed on both sides of the notch, and the pair of grooves 22 open in opposite directions. Each groove 22 is defined by a top wall and a bottom wall. The edge 121 of the powder bucket 12 can be supported by the bottom wall or clamped by the locking block 24 and the top wall. In another embodiment, the groove 22 may only have a top wall and no bottom wall. In this case, the edge 121 of the powder bucket 12 can only be clamped by the locking block 24 and the top wall.

[0042] In one embodiment, the top of the powder container 12 has a protruding edge 121 extending outwards from the periphery. The edge 121 can be as follows: Figure 3 The pair of partially thinned structures located on both sides of the top of the powder bucket 12, as shown, cooperate with the groove 22 to ensure that the powder bucket 12 can only be positioned within the notch in a defined direction. In another embodiment, the edge 121 can also be a uniform thickness flange structure on the top of the powder bucket 12 (this embodiment is not shown in the figure), with the outer periphery of the uniform thickness flange embedded in the groove 22.

[0043] To ensure that the powder bucket 12 can be placed in a fixed position on the storage rack, thereby improving the alignment efficiency when the drive assembly 11 is connected to the powder bucket 12, this utility model is provided with a clamping assembly, which consists of a clamping block 24 and an elastic element 25. Under the elastic force of the elastic element 25, the clamping block 24 can block the opening 23 of the notch, thereby positioning the powder bucket 12 in a fixed position within the notch.

[0044] In one embodiment, such as Figure 2-4 As shown, the locking block 24 consists of a blocking portion 241 near the opening 23 and a supporting portion 242 away from the opening 23. The blocking portion 241 is higher than the supporting portion 242 in the third direction z, and the supporting portion 242 is strip-shaped along the first direction x, thereby supporting the edge portion 121 on the top surface of the supporting portion 242, or clamping the edge portion 121 by the top surface of the supporting portion 242 and the bottom surface of the top wall of the groove portion 22. In another embodiment, the locking block 24 may only include the blocking portion 241 without the supporting portion 242. In this case, the edge portion 121 is directly supported by the top surface of the bottom wall of the groove portion 22 after passing the blocking portion 241.

[0045] In one embodiment, the elastic element 25 is a coil spring or disc spring and is disposed between the bottom of the locking block 24 and the bottom wall of the groove 22, or disposed within a recess in the bottom wall of the groove 22. When the elastic element 25 is compressed, the locking block 24 releases a portion of the opening 23 area to allow the edge 121 to pass through. In another embodiment, the elastic element 25 is a leaf spring, which is connected to both the locking block 24 and the groove 22. When the leaf spring is elastically bent, the locking block 24 releases a portion of the opening 23 area to allow the edge 121 to pass through.

[0046] In one embodiment, the locking block 24 has a slope 243 formed in any one or both directions toward the opening 23 and away from the opening 23. When the edge 121 contacts the slope 243 along the first direction x, the oblique component force causes the locking block 24 to compress the elastic member 25 and release part of the opening 23. When the edge 121 is placed in the notch or completely removed from the notch, the locking block 24 automatically closes the groove 22 at the opening 23 under the action of the elastic restoring force.

[0047] In one embodiment, the frame 21 has a stop 2814 at the opening 23 of the groove. The stop 2814 extends in the z-direction. When the powder bucket 12 is not inserted into the notch, the stop 24 is pressed against the top wall of the groove 22 by the elastic member 25. The gap between the stop 24 and the bottom wall of the groove 22 is relatively large, and the edge 121 is easily accidentally inserted into this gap. By setting the stop 2814, this gap can be blocked, avoiding accidental insertion.

[0048] In one embodiment, the clamping assembly is further provided with a bracket 26 and a guide post 27. The bracket 26 is connected to the frame 21 below the notch by the guide post 27. A rubber pad 261 is provided on the upper surface of the bracket 26. The position of the rubber pad 261 corresponds to the notch, so that when the powder bucket 12 is supported in the notch, the powder outlet at the bottom of the powder bucket 12 can be pressed on the rubber pad 261, thereby sealing the powder outlet.

[0049] In one embodiment, the card block 24 and the bracket 26 are connected as a whole by the guide post 27. The guide post 27 passes through the frame 21 and can guide the card block 24 and the bracket to move as a whole along the third direction z. The distance between the supporting part 242 of the card block 24 and the bracket 26 is set to a fixed value, thereby ensuring that the powder outlet of the powder bucket 12 can be accurately sealed by the rubber pad 261.

[0050] In one embodiment, the top of the sample feeding mechanism 10 is connected to the feeding mechanism via a movable frame, thereby being driven to move along mutually orthogonal first directions x and second directions y. Exemplary driving methods may include chain drive, belt drive, rack and pinion drive, screw and nut drive, etc.

[0051] In one embodiment, the sample dispenser is further provided with a drying module and an antistatic module. For example, the drying module is selected from an electronic dryer, and the antistatic module is selected from an ionization antistatic device.

[0052] In one embodiment, such as Figure 5 As shown, the sample dispenser is also equipped with a powder receiving mechanism. For example, the powder receiving mechanism consists of a swing motor 42, a swing rod 43, and a tray 41. The output shaft of the swing motor 42 drives the swing rod 43 to rotate, thereby aligning the tray 41 with the bottom of the powder outlet. In another example, the powder receiving mechanism drives the tray 41 to move linearly, thus aligning the tray 41 with the bottom of the powder outlet. In specific operation, after the sample dispensing operation is completed, the linear cylinder 44 drives the sample dispensing mechanism 10 to rise along the third direction z, and then controls the tray 41 to move to the alignment position below the powder outlet, thereby preventing solid powder leaking from the powder outlet from falling into the container below.

[0053] According to the multi-channel solid sampler of this utility model embodiment, after the addition of a solid powder raw material is completed, the feeding mechanism drives the sample adding mechanism to move to the powder barrel storage rack. After the powder barrel is inserted into the opening 23, the sample adding mechanism can be lifted to easily separate the driving component from the powder barrel. Then, it is moved to another powder barrel storage position and the sample adding mechanism is pressed down so that the sample adding mechanism can be quickly assembled with the powder barrel by magnetic attraction. After the sample adding mechanism is removed from the opening 23, the next sample adding action can be performed. The whole process can quickly realize the addition of multiple types of solid powder raw materials, and the so-called "multi-channel" rapid sample adding.
