As shown in fig. 1 to 3, the automatic sampling swab dispensing device according to the embodiment of the present invention includes a housing 100, a conveying table 200, and a storage box 300, wherein the housing 100 is a three-dimensional rectangular structure or other structures, a cavity 110 is disposed therein, a feeding port 120 is disposed on a top surface of the housing 100, a dispensing slot 130 and a control panel 400 are disposed on a front side surface of the housing 100, the control panel 400 is electrically connected to a controller (not shown in the drawings) disposed inside the housing 100, the controller includes but is not limited to a single chip microcomputer, an FPGA, or a PLC, and four supporting legs 140 are disposed on a bottom surface of the housing 100.

As shown in fig. 2 to 4, the magazine 300 and the transport table 200 are both disposed inside the housing 100, and the magazine 300 is used for storing sampling swabs and has a structure that is wide at the top and narrow at the bottom. The top of the storage case 300 is a feeding hole 320, and the bottom of the storage case 300 is a discharging hole 310, wherein the feeding hole 320 extends to the top surface of the housing 100 and forms a feeding port 120 of the housing 100, a user can feed a certain number of sampling swabs into the storage case 300 through the feeding port 120, and the size of the discharging hole 310 is slightly larger than that of the sampling swabs, so that the discharging hole 310 can only pass one sampling swab at a time.

In addition, the conveying table 200 includes a supporting frame 210 and a conveying belt 220, the supporting frame 210 is fixedly connected to the casing 100, the conveying belt 220 is a conventional conveying belt, and includes a driving belt 221, a driving shaft 222, a driven shaft 223 and a motor 224, the operation of the motor 224 is controlled by the controller, the driving shaft 222 and the driven shaft 223 are both rotatably connected to the supporting frame 210, the driving belt 221 may be a belt, the driving shaft 222 and the driven shaft 223 are spaced from each other in front and back and are in transmission connection through the driving belt 221, and the motor 224 may be directly connected to the driving shaft 222 or in transmission connection with the driving shaft 222 through a transmission mechanism 225. In order to optimize the spatial position, the present invention preferably connects the motor 224 and the driving shaft 222 in a transmission manner through the transmission mechanism 225, the transmission mechanism 225 may be selected as a synchronous belt transmission mechanism 225, and at this time, the motor 224 may be located below the conveying belt 220. When the motor 224 operates, the motor 224 can drive the driving shaft 222 to rotate, and the driven shaft 223 is in a passive rotation state, so that the motor 224 can drive the transmission belt 221 to rotate, thereby conveying materials.

The conveying belt 220 has a conveying direction from back to front, and for convenience of description, the back end of the conveying belt 220 may be defined as a starting end 201, and the front end of the conveying belt 220 may be defined as a terminating end 202. The discharge hole 310 of the storage case 300 is located above the starting end 201, so that the sampling swabs located in the storage case 300 can fall to the starting end 201 of the conveying belt 220 under the action of gravity. The dispensing slot 130 of the housing 100 interfaces with the terminus end 202 of the conveyor belt 220 such that a sampling swab dropped onto the conveyor belt 220 can be conveyed into the dispensing slot 130, the dispensing slot 130 having an arcuate slot bottom that can temporarily stack a number of sampling swabs to prevent the sampling swabs from falling out of the housing 100.

To detect the dispensed number of sampling swabs, the transporter table 200 is equipped with a counting sensor 230 at the destination end 202 of the transporter belt 220, the counting sensor 230 is electrically connected to the controller, and the counting sensor 230 is optionally a photoelectric sensor for recording the number of sampling swabs passing through the destination end 202. When the user sets and executes the dispensing amount of the sampling swabs on the control panel 400, the controller immediately sends an operation instruction to the motor 224, once the conveyor belt 220 is in the working state, the sampling swabs in the magazine 300 continuously drop from the discharge port 310 to the starting end 201 of the conveyor belt 220, the conveyor belt 220 can convey the sampling swabs from the starting end 201 to the destination end 202 in the working state, in the process, the counting sensor 230 records the amount of the sampling swabs passing through the destination end 202, when the amount recorded by the counting sensor 230 is equal to the dispensing amount set by the user, the controller stops the operation of the motor 224, and the sampling swabs at the destination end 202 can drop into the dispensing slot 130 under the effect of inertia, so that the quantitative dispensing of the sampling swabs is realized.

Further, the quantitative distribution of the sampling swabs is still not satisfied only by the above-mentioned structure, because it is difficult for the counting sensor 230 to accurately detect the actual number of sampling swabs when the sampling swabs are stacked. In order to solve the technical problem, the conveying platform 200 is provided with a limiting frame 500 above the conveying belt 220, the limiting frame 500 includes two base plates 510 and a plurality of limiting rods 520, the two base plates 510 are respectively connected to the left and right ends of the supporting frame 210, all the limiting rods 520 are connected between the two base plates 510, and all the limiting rods 520 are sequentially arranged along the conveying direction of the conveying belt 220, the distance from each limiting rod 520 to the conveying belt 220 is greater than the height of one sampling swab but less than the height of two sampling swabs, and the distance is preferably 1.3 sampling swabs, so that a single-layer conveying space 501 is defined between the limiting frame 500 and the conveying belt 220 to prevent the sampling swabs from being stacked during conveying, and the counting sensor 230 at the terminal end 202 can accurately detect the distribution number of the sampling swabs, thereby realizing quantitative distribution of the sampling swabs.

In other embodiments, the limiting rod 520 can be rotatably connected between the two base plates 510, and the limiting rod 520 can freely rotate in the form of a roller, so as to facilitate the transportation of the sampling swab.

It should be further noted that, because the conveying belt 220 has a certain conveying speed, and the size of the discharge port 310 of the storage box 300 is slightly larger than that of the sampling swabs, the sampling swabs in the storage box 300 generally drop onto the conveying belt 220 intermittently, even though the sampling swabs are stacked occasionally, the sampling swabs can be separated under the limiting action of the limiting frame 500, and the separated sampling swabs are arranged at intervals, so that the sampling swabs cannot be conveyed in a row.

As shown in fig. 3, in some embodiments of the present invention, in order to calculate the fuzzy number of the sampling swabs in the storage box 300, a load cell (not shown in the drawings) may be built in each of the supporting legs 140, the load cell is used for detecting the whole weight of the sampling swab automatic dispensing device, and the load cell is electrically connected to the controller. Since the net weight of the automatic sampling swab dispenser is fixed and the average weight of each sampling swab is known, when a user stores a certain number of sampling swabs in the magazine 300, the total weight of the automatic sampling swab dispenser changes with the storage amount of the sampling swabs, and the controller calculates the number of sampling swabs in the magazine 300 from the difference in weight and displays the calculated value on the control panel 400 for the user to refer to.

As shown in fig. 4, in some embodiments of the present invention, the storage case 300 is installed with an inductive sensor 330 at a designated height, the inductive sensor 330 is electrically connected to the controller, and the inductive sensor 330 can be selected as a photoelectric sensor. The inductive sensor 330 is used for detecting the storage height of the sampling swabs in the magazine 300, and when the storage height of the sampling swabs is lower than a specified height, the controller sends out a reminding signal which is transmitted outwards in a sound-light mode and/or a radio mode so as to remind a user of replenishing the quantity of the sampling swabs in the magazine 300.

In some embodiments of the present invention, the automatic sampling swab dispenser is powered by a battery 600 for outdoor use. In other embodiments, the automatic sampling swab dispenser may be powered by the battery 600, while retaining a power cord to handle different operating environments.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
