Description

Technical Field

[0001] The utility model relates to the technical field of sample processing equipment, in particular to a bottle cap feeding device and sample processing equipment. Background Art

[0002] The sample processing device is a device that automatically processes biological samples, and is widely used in the field of sample detection. The sample processing device includes a bottle cap loading device.

[0003] In a laboratory environment, operators often have to operate various reagent tanks and need to take bottle caps from the bottle cap loading device to open and close the reagent tank lids. For example, a reagent tank containing liquid after sample filtration needs to take the bottle cap from the bottle cap loading device to close the lid for subsequent use; or, after the reagent tank containing the original sample is opened, in order to avoid contamination of the opened bottle cap by the sample after being left for a period of time, a new bottle cap needs to be taken from the bottle cap loading device to close the lid to avoid contamination for subsequent use.

[0004] However, daily bottle cap sorting is a complicated task. When loading bottle caps into reagent tanks, a large number of bottle caps need to be arranged and adjusted in angle to facilitate grabbing the bottle caps and closing the caps. Therefore, it is necessary to avoid the bottle caps from being intertwined with each other (for example, two bottle caps are stacked and stuck in the bottle cap feeding device). This can easily cause confusion in the bottle cap sorting and make it impossible to ensure that the next bottle cap can be in place in time when the bottle caps are taken, resulting in insufficient bottle cap feeding efficiency. At the same time, it is necessary to avoid the use of traditional bottle cap feeding devices and the use of conveyor belts to transport bottle caps, which causes high noise, large space and blocked discharge ports. These problems need to be solved urgently. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a bottle cap feeding device is provided, and the technical solution is as follows.

[0007] The bottle cap feeding device of the present invention, on the one hand, is based on a storage bin for storing bottle caps in a stacked manner, and a picking assembly clamps the bottle caps from below the material rack, which saves space and thus can increase the operating space; on the other hand, since an anti-blocking member is added to the surface of the bottle cap located at the top in the storage bin, the bottle cap can fall smoothly under the pressure of the anti-blocking member, and after the picking assembly clamps and takes away the bottle cap located at the bottom in the storage bin, it ensures that the remaining bottle caps will not be stuck in the middle of the storage bin of the material rack, so that the next bottle cap can be in place in time, which not only simplifies the bottle cap feeding process and improves the bottle cap feeding efficiency, but also reduces the high-decibel noise during the feeding process.

[0008] Exemplarily, the material rack includes a material rack body, a discharge port is arranged at the lower end of the material rack body and is suspended relative to the base, and the material taking component is arranged beside the discharge port.

[0010] Exemplarily, the rack body has a cylindrical portion and an extension portion, the internal cavity of the cylindrical portion forms a storage bin, the extension portion extends from the outer wall surface of the cylindrical portion away from the storage bin, and a portion of the extension portion is connected to the connecting piece.

[0011] Exemplarily, the upper surface of the connecting member gradually inclines toward the base from the rack body to the end away from the storage bin.

[0012] Exemplarily, the base has a main body and a rotating part, the rotating part is rotatably connected to the main body, and the material rack is fixedly connected to the rotating part so as to be rotatable relative to the main body.

[0013] Exemplarily, a blocking member is provided on the main body around the material rack, and the blocking member has an opening.

[0014] Exemplarily, a plurality of observation ports are arranged on the material rack at intervals along the loading direction.

[0015] Exemplarily, the material picking assembly includes a clamping jaw, a first driving member, a second driving member and a third driving member; the first driving member is connected to the clamping jaw to drive the clamping jaw to close and clamp the bottle cap or drive the clamping jaw to open and loosen the bottle cap; the second driving member is connected to the first driving member to drive the clamping jaw to move between a first position and a second position along a first direction through the first driving member; the third driving member is connected to the second driving member to drive the clamping jaw to rotate between a first position and a third position in a plane in the first direction through the second driving member and the first driving member; wherein, when the clamping jaw is in the first position, it is away from the discharge port; when the clamping jaw moves to the second position, it is located directly below the discharge port; when the clamping jaw rotates to the third position, it is farther away from the discharge port than the first position.

DETAILED DESCRIPTION

[0028] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0029] To thoroughly understand the embodiments of the present invention, a detailed structure will be provided in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0030] The embodiment of the present invention provides a bottle cap loading device. The bottle cap loading device of the present invention can be applied to a sample processing device. The bottle cap loading device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1 and Figure 5The bottle cap loading device 10 may include a base 110, a material rack 120, an anti-blocking member 130 and a material taking assembly 140. The material rack 120 may be set on the base 110, and the material rack 120 may have a storage bin 121 for storing bottle caps in a stacked manner. The storage bin 121 may have a loading port 1211 and a discharging port 1212. The anti-blocking member 130 may be pressed against the surface of the bottle cap located at the top in the storage bin 121 from the loading port 1211. The material taking assembly 140 may be located below the material rack 120. The material taking assembly 140 may clamp the bottle cap located at the bottom in the storage bin 121 from the discharging port 1212.

[0032] The bottle cap loading device 10 of the present invention, on the one hand, is based on the fact that the material rack 120 has a storage bin 121 for storing bottle caps in a stacked manner, and the picking component 140 clamps the bottle caps from below the material rack 120, which saves space and thus can increase the operating space; on the other hand, since the anti-blocking member 130 is added to the surface of the top bottle cap in the storage bin 121, the bottle cap can fall smoothly under the pressure of the anti-blocking member 130. After the picking component 140 clamps and takes away the bottle cap at the bottom of the storage bin 121, it ensures that the remaining bottle caps will not be stuck in the middle of the storage bin 121 of the material rack 120, so that the next bottle cap can be in place in time. Not only is the bottle cap loading process simple and the bottle cap loading efficiency improved, but the high-decibel noise of the loading process can also be reduced.

[0033] Furthermore, the weight of the anti-blocking member 130 must be greater than the weight of the bottle cap so that the bottle cap can fall smoothly under the pressure of the anti-blocking member 130. In this way, the anti-blocking member 130 can be a counterweight block, such as an iron block, aluminum block or other metal block, which is not only low in cost but also convenient for production and processing.

[0034] See also Figure 1 and Figure 3 The material rack 120 may include a material rack body 122. The discharge port 1212 may be provided at the lower end of the material rack body 122 and suspended relative to the base 110. The picking assembly 140 may be provided beside the discharge port 1212. The discharge port 1212 is provided at the lower end of the material rack body 122, which can facilitate the picking assembly 140 to clamp the bottle caps and facilitate the next bottle cap to fall to the discharge port 1212 under the action of gravity, thereby improving the bottle cap loading efficiency. It should be noted that the discharge port 1212 corresponds to the side of the picking assembly 140 used to clamp the bottle caps. The height at which the discharge port 1212 is suspended is consistent with the height of a bottle cap, thereby improving the accuracy of the picking assembly 140 in clamping the bottle caps, and avoiding the phenomenon that the discharge port 1212 is suspended too high, resulting in the picking assembly 140 being offset or carried out of the discharge port 1212 when the bottle cap above it falls when clamping the bottom bottle cap.

[0035] See also Figure 1 、 Figure 3 and Figure 4The rack 120 may further include a connector 123. The rack body 122 may be fixed to the base 110 via the connector 123. Compared to directly connecting the rack body 122 to the base 110, the fixed connection between the rack body 122 and the base 110 via the connector 123 occupies less space, thereby saving space and ensuring the stability of the rack body 122. The connector 123 has a certain length in the direction away from the rack body 122, thereby acting as a reinforcing rib, ensuring that the fulcrum at the bottom of the rack body 122 can be longer, lowering the center of gravity of the rack body 122, and thus improving the stability of the rack body 122.

[0036] See also Figure 4 and Figure 5 The rack body 122 may have a cylindrical portion 1221 and an extension portion 1222. The internal cavity of the cylindrical portion 1221 may form a storage bin 121. The extension portion 1222 may extend from the outer wall surface of the cylindrical portion 1221 away from the storage bin 121, and a portion of the extension portion 1222 may be connected to the connector 123. The rigidity and strength of the cylindrical portion 1221 are ensured by the extension portion 1222, the volume of the rack body 122 is reduced, space is saved, and costs are reduced. Specifically, the extension portion 1222 may extend from the outer wall surface of the cylindrical portion 1221 away from the storage bin 121 into a stepped shape with a width gradually reduced from the diameter of the cylindrical portion 1221, so as to further reduce the volume of the rack body 122, thereby saving space.

[0037] Again, refer to Figure 4 and Figure 5 The upper surface 1231 of the connecting member 123 can gradually slope toward the base 110 from the rack body 122 to the end away from the storage bin 121. This prevents operators from being scratched by the connecting member 123 when removing the rack body 122, further reduces the size of the rack 120, and saves space. Specifically, the connecting member 123 can be connected to the middle and lower portion of the extension 1222, ensuring the stability of the rack body 122 while saving space.

[0038] See Figure 1Multiple racks 120 can be provided, and these racks 120 can be spaced apart on the base 110, and the racks 120 can be cylindrical in shape. Compared to a linear arrangement of racks 120, the cylindrical structure is more compact, resulting in more efficient use of space. Specifically, when the bottle cap loading device 10 is in operation, only one rack 120 can be in operation, or multiple racks 120 can be in operation simultaneously. When only one rack 120 is in operation, an operator or a robotic arm can restock the remaining racks 120. When the bottle caps in the active rack 120 are used up, the remaining racks 120 can promptly replace it and continue loading. This ensures continuous loading and improves loading efficiency. When multiple racks 120 are in operation simultaneously, it is suitable for scenarios with high demand for bottle caps, thereby improving loading efficiency.

[0039] Again, refer to Figure 1 and Figure 3 The base 110 may have a main body 111 and a rotating part 112. The rotating part 112 may be rotatably connected to the main body 111. Specifically, the base 110 may rotate the rotating part 112 relative to the main body 111 manually, by a motor, or by an air bearing. The material rack 120 is fixedly connected to the rotating part 112 so as to be rotatable relative to the main body 111. The rotating part 112 drives the material rack 120 to rotate relative to the main body 111, thereby facilitating the material rack 120 to quickly and accurately reach the material picking position corresponding to the material picking assembly 140. In order to correspond to the cylindrical arrangement of multiple groups of material racks 120, the base 110 for setting the material rack 120 may be cylindrical. Compared with the linear base 110, the cylindrical base 110 occupies less space and saves space.

[0040] See also Figure 1 、 Figure 4 and Figure 5 , a blocking member 1111 may be provided on the main body 111 around the material rack 120. The blocking member 1111 may have an opening 1111a. When the material rack 120 rotates to the point where the discharge port 1212 is opposite to the opening 1111a, the material picking assembly 140 may clamp the bottle cap located at the bottom of the storage bin 121 through the opening 1111a. By providing the blocking member 1111, the bottle cap located at the discharge port 1212 is limited to avoid the phenomenon of the bottle cap located at the discharge port 1212 flying out. Specifically, the opening 1111a can only correspond to one group of material racks 120 to facilitate precise correspondence with the material picking assembly 140, and avoid the opening 1111a being too large, resulting in the blocking member 1111 being unable to limit the bottle cap located at the discharge port 1212.

[0041] Again, refer to Figure 1 、 Figure 4 and Figure 5 The material rack 120 may be provided with a plurality of observation ports 124 spaced apart along the loading direction. Through the observation ports 124, the use of the bottle caps in the storage bin 121 can be observed, allowing for timely loading or replacement of other material racks 120. Furthermore, through the observation ports 124, it is possible to observe whether the bottle caps stacked in the storage bin 121 are stuck or intertwined, facilitating timely processing and thereby improving the efficiency of bottle cap loading. Specifically, the observation ports 124 may be provided with a plurality of runway-shaped holes along the loading direction, each hole being provided at a stack of bottle caps, to facilitate observation of the bottle caps in the storage bin 121. The observation ports 124 may also be elongated strips along the loading direction to facilitate processing while preventing the observation ports 124 from affecting the smoothness of the bottle caps falling. Of course, the observation ports 124 may also have other shapes, but they must ensure the strength of the material rack body 122 while preventing the bottle caps from escaping through the observation ports 124.

[0042] See also Figure 1 and Figure 2 The material removal assembly 140 may include a clamping jaw 141, a first driving member 142, a second driving member 143, and a third driving member 144. The first driving member 142 may be connected to the clamping jaw 141 to drive the clamping jaw 141 to close and grasp the bottle cap, or to drive the clamping jaw 141 to open and release the bottle cap. The second driving member 143 may be connected to the first driving member 142 to drive the clamping jaw 141 to move along the first direction X between a first position and a second position via the first driving member 142. The third driving member 144 may be connected to the second driving member 143 to drive the clamping jaw 141 to rotate between a first position and a third position within the plane of the first direction X via the second driving member 143 and the first driving member 142. When the clamping jaw 141 is in the first position, it may be away from the discharge port 1212. When the clamping jaw 141 moves to the second position, it may be directly below the discharge port 1212. When the gripper 141 rotates to the third position, it can be further away from the discharge port 1212 than in the first position. The picking assembly 140 can accurately pick up bottle caps for transport, preventing them from getting stuck when leaving the discharge port 1212. Compared to a conveyor belt, the picking assembly 140 occupies less space, thus saving space.

[0043] Again, refer to Figure 1 and Figure 2The material removal assembly 140 may further include a bottle cap adapter 145. The bottle cap adapter 145 may be disposed adjacent to the third drive member 144. The bottle cap adapter 145 is connected to a fourth drive member 146 and is driven by the fourth drive member 146 to move along the second direction Y between a receiving position and a transfer position. When the clamping jaws 141 rotate to the third position, the bottle cap adapter 145 may move to the receiving position to receive bottle caps released from the clamping jaws 141. The second direction Y may be perpendicular to the plane of the first direction X. By allowing the bottle cap adapter 145 to move along the second direction Y to transport the bottle caps, space in the second direction Y is more efficiently utilized, making it suitable for use in environments with limited space. The receiving position may be where the bottle cap adapter 145 is located below the bottle caps gripped by the clamping jaws 141, and the transfer position may be where the bottle cap adapter 145 transfers the bottle caps to the assembly for opening and closing the lid.

[0044] The first driving member 142 , the second driving member 143 , the third driving member 144 and the fourth driving member 146 may be motors or cylinders.

[0045] Specifically, the first driving member 142 can be slidably connected to the clamping jaw 141 by forming a protrusion 1411 in the direction where the clamping jaw 141 approaches the first driving member 142, and V-shaped protrusions 1411a can be respectively protruded on the two side surfaces along the second direction Y of the protrusion 1411. The end surface of the first driving member 142 close to the clamping jaw 141 can have a groove 1421, and V-shaped grooves 1421a can be respectively recessed on the two side surfaces along the second direction Y of the groove 1421. The V-shaped protrusions 1411a of the clamping jaw 141 are limited in the V-shaped grooves 1421a and slide to slidably connect to the first driving member 142. In this way, the connection method between the first driving member 142 and the clamping jaw 141 is simple and easy to disassemble and assemble for maintenance and replacement. In embodiments not shown in the present invention, the combination of the V-shaped grooves 1421a and the V-shaped protrusions 1411a can also be a combination of a square groove and a square protrusion or a combination of a polygonal groove and a polygonal protrusion, etc. Of course, the connection between the clamping jaw 141 and the first driving member 142 includes but is not limited to the above-mentioned connection methods. For example, they can also be connected through a slide rail or other connection methods.

[0046] The second driving member 143 may include a main body 1431 and a telescopic body 1432 that extends or retracts relative to the main body 1431 in a first direction X. The first driving member 142 may be mounted on the telescopic body 1432. Specifically, the second driving member 143 may be a slide cylinder, the main body 1431 may be a cylinder, and the telescopic body 1432 may be a push rod and a slide. The cylinder uses air pressure as a power source to cause a piston to push the push rod, driving the slide in linear motion. This, in turn, drives the clamping jaw 141 along the first direction X between a first position and a second position via the first driving member 142. This facilitates the retrieval assembly 140 to approach the material rack 120 and retrieve bottle caps.

[0047] The third driving member 144 may include a main body 1441 and a rotating body 1442. The rotating body 1442 is rotatably connected to the main body 1441. The second driving member 143 is connected to the rotating body 1442. The second driving member 143 and the first driving member 142 drive the clamping jaw 141 to rotate between a first position and a third position within a plane corresponding to the first direction X. Specifically, the rotating body 1442 may rotate relative to the main body 1441 via an air bearing. This facilitates the transport of bottle caps by the retrieving assembly 140.

[0048] The fourth driving member 146 can have a driving part 1461 and a telescopic part 1462 that can be telescoped relative to the driving part 1461 along the second direction Y. The bottle cap adapter 145 can be connected to the telescopic part 1462. The bottle cap adapter can be cylindrical with a diameter less than or equal to the diameter of the bottle cap to facilitate receiving the bottle cap and avoid the bottle cap falling when moving between the receiving position and the transfer position.

[0049] Specifically, the feeding process of the bottle cap feeding device 10 is described in conjunction with Figures 1 to 5After bottle caps are loaded into the storage bin 121 from the loading port 1211 by a robot or an operator, an anti-blocking member 130 is installed on the surface of the top bottle cap in the storage bin 121. The rotating portion 112 of the base 110 drives the multiple groups of racks 120 to rotate until the group of racks 120 to be worked on corresponds to the opening 1111a of the blocking member 1111 on the main body 1441 portion 111 of the base 110. The second driving member 143 of the picking assembly 140, located next to the discharge port 1212 of the rack 120, moves the first driving member 142 and the clamping jaw 141 from the first position to the second position. The first driving member 142 drives the clamping jaw 141 from the discharge port 1212 to clamp the bottom bottle cap in the storage bin 121. The second driving member 143 then moves the first driving member 142 and the clamping jaw 141, which is clamping the bottle cap, back to the first position. At this time, since the bottom bottle cap in the storage bin 121 is taken away by the picking assembly 140, the remaining bottle caps in the storage bin 121 fall smoothly due to the pressure of the anti-blocking member 130 until the next bottle cap is located at the discharge port 1212. At the same time, the third driving member 144 causes the second driving member 143 and the first driving member 142 to drive the clamping jaw 141 holding the bottle cap to rotate from the first position to the third position within the plane of the first direction X. The clamping jaws 141 release the bottle caps, causing the bottle caps to fall onto the bottle cap adapter 145 located at the receiving position. The bottle cap adapter 145, driven by the fourth driving member 146, drives the bottle caps to move to the transfer position along the second direction Y. The component for opening and closing the caps removes the bottle caps on the bottle cap adapter 145 to complete one loading. The above operation is repeated until the bottle caps in the storage bin 121 are seen to be used up from the observation port 124 of the material rack 120. The group of material racks 120 filled with bottle caps in the storage bin 121 can be rotated to the corresponding position of the opening 1111a by the rotating part 112 to continue loading. The material racks 120 can also be disassembled in time to replenish bottle caps in the storage bin 121, and then the material racks 120 can be installed to continue loading.

[0050] According to one aspect of the present invention, a sample processing device is provided. The sample processing device may include a frame and the bottle cap loading device 10 described above. The bottle cap loading device 10 may be mounted on the frame. Since the bottle cap loading device 10 described above has the aforementioned beneficial effects, the sample processing device including the bottle cap loading device 10 also has the aforementioned beneficial effects, which will not be further elaborated herein.

[0051] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front", "back", "up", "down", "left", "right", "horizontal", "vertical", "vertical", "horizontal", "top", "bottom", etc. are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0052] For ease of description, area-relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the regional positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that area-relative terms include not only the orientation of the components as described in the figures, but also different orientations in use or operation. For example, if the components in the drawings are inverted as a whole, the situation where the components are "above other components or features" or "above other components or features" will include the situation where the components are "below other components or structures" or "below other components or structures". Thus, the exemplary term "above" may include both the orientations "above" and "below". In addition, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document is intended to include all of these situations.
