Description

Technical Field

[0001] The invention relates to the technical field of automatic product dispensing, and in particular to an automatic dispensing device for disposable sample adding needles. Background Art

[0002] Disposable sample needles are commonly used accessories in clinical testing medical equipment. They have a relatively slender structure and are usually made of plastic materials through injection molding. Currently, most of the disposable sample needles sold on the market are bagged and in a disordered state. Before use, the instrument operator needs to first load the bulk disposable sample needles into the needle box, and then put the needle box into the testing equipment for clinical experiments. This not only wastes time, but also easily causes secondary pollution.

[0003] In view of the above situation, some devices for repackaging bulk disposable sample needles have appeared on the market, replacing the manual repackaging process and avoiding secondary contamination caused by human factors. However, it is still inevitable to waste a lot of time on repackaging disposable sample needles. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a disposable sample adding needle automatic packaging device for directly packaging the disposable sample adding needle when the injection molding is completed and the mold is ejected, thereby avoiding the time waste of packaging before subsequent use.

[0005] The objective of the present invention is achieved through the following technical scheme: a disposable automatic dispensing device for sample adding needles, comprising a flipping mechanical arm, a needle drop plate is arranged below the flipping mechanical arm, a plurality of needle drop openings corresponding to the acupoints of the mold are arranged on the needle drop plate, a hose is connected below the needle drop opening, the other end of the hose is connected to a minute needle plate, the minute needle plate is provided with the same number of minute needle positions as the needle drop openings, a needle box platform is arranged below the minute needle plate, a needle box rack is arranged on the needle box rack, a needle box is placed on the needle box rack.

[0006] In the above-mentioned automatic dispensing device for disposable sample needles, the flipping robot arm takes over the disposable sample needle from the injection molding machine robot when the disposable sample needle is ejected from the mold, and flips it so that the tip of the disposable sample needle faces downward, passes through the needle drop port and the hose to the minute needle position on the minute needle plate, and then falls into the needle box corresponding to the minute needle position below the minute needle position through the minute needle position. The dispensing time is equivalent to the injection molding cycle of the disposable sample needle, and no additional time is required for dispensing, thereby avoiding the waste of time for dispensing before subsequent use.

[0007] As an improvement to the present invention, the needle plate can be translated so that the disposable sample adding needle can fall into any position of the needle box.

[0008] As another improvement to the present invention, the minute needle plate includes a base, a cylinder is installed on the base, the front end of the cylinder is connected to the cylinder connecting seat, and a pull plate is installed on the cylinder connecting seat. The minute needle position includes a guide tube and a stop rod, and a notch is opened on the guide tube. One end of the stop rod is clamped on the notch of the guide tube to limit the disposable sample adding needle. The middle part of the stop rod is fixed to the base by a positioning pin, and the other end of the stop rod is fixed to the pull plate. The movement of the cylinder drives the movement of the cylinder connecting seat and the pull plate, and the pull plate drives the stop rod to rotate around the positioning pin to realize the control of the disposable sample adding needle packaging process.

[0009] As an improvement to the minute hand plate of the present invention, a torsion spring is installed between the baffle rod and the base, one end of the torsion spring is fixed to the base, and the other end is fixed to the baffle rod.

[0010] As another improvement to the minute hand plate of the present invention, a guide pin is installed on the base, a guide groove is opened on the pull plate, and the guide groove is clamped on the guide pin to guide the movement of the pull plate.

[0011] Combined with the structural characteristics of the present invention, compared with the prior art, the present invention provides an automatic dispensing device for disposable sample adding needles, which has the following beneficial effects: the present invention realizes direct dispensing after the disposable sample adding needles are injection molded, and the dispensing time is equivalent to the injection molding cycle of the disposable sample adding needles, so no extra time is needed for dispensing, thereby avoiding the waste of time for dispensing before subsequent use.

DETAILED DESCRIPTION

[0017] To explain the technical features and achieved purposes and effects of the present invention in detail, further description is given below in conjunction with the accompanying drawings:

[0018] like Figures 1 to 4 As shown, the present invention provides an automatic dispensing device for disposable sample adding needles, comprising a flipping robot arm 1, a needle drop plate 2 is provided below the flipping robot arm 1, a plurality of needle drop openings 3 corresponding to the acupuncture points of the mold are provided on the needle drop plate 2, a hose 4 is connected below the needle drop opening 3, the other end of the hose 4 is connected to a minute needle plate 5, the minute needle plate 5 is provided with minute needle positions 19 having the same number as the needle drop opening 3, a needle box platform 9 is provided below the minute needle plate 5, a needle box rack 8 is provided on the needle box platform 9, a needle box 7 is placed on the needle box rack 8.

[0019] Preferably, the needle plate 5 can be translated so that the disposable sample adding needle 6 can fall into any position of the needle box 7 .

[0020] Preferably, the minute hand plate 5 includes a base 20 and a minute hand position 19, a cylinder 10 is installed on the base 20, the front end of the cylinder 10 is connected to the cylinder connecting seat 11, a pull plate 18 is installed on the cylinder connecting seat 11, the minute hand position 19 includes a guide tube 12 and a stop rod 16, a notch is opened on the guide tube 12, one end of the stop rod 16 is stuck in the notch of the guide tube 12, the middle part of the stop rod 16 is fixed to the base 20 by a positioning pin 17, and the other end of the stop rod 16 is fixed to the pull plate 18.

[0021] Preferably, a torsion spring 15 is installed between the blocking rod 16 and the base 20 , and one end of the torsion spring 15 is fixed to the base 20 , and the other end is fixed to the blocking rod 16 .

[0022] Preferably, a guide pin 14 is installed on the base 20 , and a guide groove 21 is opened on the pull plate 18 , and the guide groove 21 is clamped on the guide pin 14 .

[0023] The present invention provides a disposable sample adding needle automatic dispensing device, and its specific implementation steps are as follows:

[0024] After the injection molding of the disposable sample adding needle 6 is completed, the injection molding machine robot 22 takes the disposable sample adding needle 6 out of the mold. According to the common sense of injection molding, the disposable sample adding needle 6 is in a state of being demoulded from the mold with the tip facing outward. Therefore, the injection molding machine robot 22 takes out the disposable sample adding needle 6 with the tip facing inward. The flipping robot arm 1 sucks the disposable sample adding needle 6 with the tip facing outward and flips it so that the disposable sample adding needle 6 faces the needle drop port 3 on the needle drop plate 2. At this time, the flipping robot arm 1 releases the disposable sample adding needle 6, and the disposable sample adding needle 6 falls into the hose 4 through the needle drop port 3, and falls into the minute needle position 19 on the minute needle plate 5 through the hose 4, and falls into the needle box 7 located below it through the minute needle position 19. Since the number of the needle drop port 3 and the minute needle position 19 is consistent with the mold acupuncture points, the disposable sample adding needle 6 formed each time can be packaged at one time. The time from demoulding to packaging to the needle box of the disposable sample adding needle 6 is short, which can basically be consistent with the injection molding cycle of the mold.

[0025] The minute needle plate 5 can be translated so that the minute needle position 19 located thereon can be aligned with any position of the needle box 7, and the disposable sample adding needle 6 can be dropped therein until the needle box 7 is filled.

[0026] When the disposable sample adding needle 6 needs to be packaged, the cylinder 10 contracts, the cylinder connecting seat 11 pulls back the pull plate 18, the pull plate 18 drives the blocking rod 16 to rotate around the positioning pin 17, the torsion spring 15 is compressed, and the blocking rod 16 leaves the notch on the guide tube 12, so that the disposable sample adding needle 6 can fall freely.

[0027] When it is necessary to limit the disposable sample adding needle 6 that falls into the minute needle plate 5, the cylinder 10 does not work, the tension acting on the cylinder connecting seat 11 and the pull plate 18 disappears, the torsion spring 15 is reset, and provides a reverse elastic force to make the blocking rod 16 rotate in the opposite direction around the positioning pin 17. The pull plate 18 also moves in the opposite direction under the action of the elastic force of the torsion spring 15, and the other end of the blocking rod 16 is stuck in the notch on the guide tube 12, forming a limit for the disposable sample adding needle 6.

[0028] The guide groove 21 formed on the pull plate 18 is clamped on the guide pin 14 on the base 20, so that the movement of the pull plate 18 is more accurate and stable, thereby ensuring the consistency of the positions of the minute hands.

[0029] The automatic dispensing device for disposable sample needles provided by the present invention can control the dispensing cycle of the disposable sample needles 6 according to the molding cycle of the mold. When the needle needs to be connected, the cylinder 10 does not work, the disposable sample needle 6 falls into the minute needle position 19 and is restricted by the blocking rod 16 and stuck on the minute needle position 19. When the disposable sample needle 6 needs to be loaded into the needle box 7, the cylinder 10 contracts, the blocking rod 16 leaves the notch on the guide tube 12, the restriction on the disposable sample needle 6 is cancelled, and the disposable sample needle 6 falls into the corresponding position in the needle box 7.
