The syringe tube positioning member is provided below the first guiding hole, and the syringe tube positioning member is used to collect the syringe tubes.

[0009] Further, the thimble member includes a plurality of thimble feet, and the thimble feet pass through the corresponding through holes.

[0010] Further, a third needle groove is provided at the upper end of the thimble pin, and the third needle groove is used for cooperating with the needle tube.

[0011] Further, a first inclined surface and a second inclined surface are respectively provided at the left and right ends of the third needle groove, and the first inclined surface and the second inclined surface are used for separating the redundant needle tube from the thimble part.

[0012] Further, in the needle storage groove on the base, a guide block protruding upward is provided between two adjacent through holes.

[0013] Further, the suction attachment is provided with a negative pressure fan, and the negative pressure fan is used for sucking or releasing the needle tube.

[0016] A clamping member disposed on the base for clamping the needle tube positioning member;

[0017] A fourth power member disposed on the base for driving the clamping member to move in the front-rear direction.

[0018] Further, the inner diameter of the first guiding hole is larger than the inner diameter of the needle tube mounting hole.

[0019] A technical solution of the second aspect of the present invention is an automatic needle tube distribution method applied to an automatic needle tube distribution device, including the following steps:

[0020] Prepare materials, place the needle tube into the needle storage groove of the base, and install the needle tube positioning member on the base;

[0021] Pick up the needle tube. The second power member drives the suction attachment to rotate above the base. The first power member drives the thimble part to move from bottom to top.

[0049] Referring to Figures 1 - 11 , a basic embodiment of the first aspect of the present invention provides a syringe automatic dispensing device, including:

[0050] A base 100 is provided with a needle storage groove 110 for storing syringes. The base 100 is provided with a number of through holes, and the through holes are arranged at the lower end of the needle storage groove 110;

[0051] A picking mechanism 200 includes a thimble member 210, a suction member 220, a first power member 230 and a second power member 240. The thimble member 210 passes through the through hole. The suction member 220 is provided with a number of first needle grooves 221, and the first needle grooves 221 correspond to the through holes one by one. The suction member 220 is rotatably arranged on the base 100. The second power member 240 drives the suction member 220 to rotate around the base 100. The second power member 240 is used to drive the suction member 220 to rotate above the base 100. The first power member 230 drives the thimble member 210 to approach the suction member 220 from bottom to top, so that the syringes on the base 100 approach the suction member 220, and then the syringes are adsorbed on the first needle grooves 221;

[0052] The collection mechanism 300 includes a third power member 310, a first guiding member 320, and a syringe positioning member 330. The first guiding member 320 is provided with a second needle groove 321. The second power member 240 drives the suction member 220 to rotate in front of the base 100. The third power member 310 drives the first guiding member 320 to approach the suction member 220. After the first needle groove 221 and the second needle groove 321 are engaged, a first guiding hole is formed. The syringe positioning member 330 is disposed below the first guiding hole, and the syringe positioning member 330 is used to collect syringes.

[0053] An automatic syringe dispensing device according to a basic embodiment of the first aspect of the present invention stores a large number of syringes through the base 100. The ejector member 210 moves upward from bottom to top, so that the ejector member 210 passes through a large number of syringes. During the upward movement, one of the syringes just remains at the upper end of the ejector member 210, and the remaining syringes remain in the syringe storage groove 110. The second power member 240 drives the suction member 220 to rotate above the base 100. The ejector member 210 moves the syringe onto the suction member 220, and the suction member 220 adsorbs the syringe on the first needle groove 221. The second power member 240 drives the suction member 220 to rotate in front of the base 100. The third power member 310 drives the first guiding member 320 to approach the suction member 220. The first guiding member 320 and the suction member 220 are in contact with each other, so that a first guiding hole is formed after the first needle groove 221 and the second needle groove 321 are engaged. At this time, the syringe is in the first guiding hole. The suction member 220 stops adsorbing the syringe, and the syringe slides along the first guiding hole due to gravity, so that the syringe just falls on the corresponding position of the syringe positioning member 330. The entire process of picking up and collecting syringes does not require manual operation, and can process multiple syringes at the same time, effectively improving production efficiency and ensuring the safety of staff.

[0054] It can be understood that the first power member 230 can be a telescopic cylinder or a telescopic motor, the second power member 240 can be a rotary motor, and the third power member 310 can be a telescopic cylinder or a telescopic motor.

[0055] It can be understood that the syringe positioning member 330 is provided with syringe mounting holes, and the syringe mounting holes correspond to the first guiding holes one by one, so that the syringes fall into the corresponding syringe mounting holes. After the dispensing is completed, there is one syringe in each syringe mounting hole.

[0056] It can be understood that the first needle groove 221 is a concave structure, so that the syringe can extend into the first needle groove 221. The first needle groove 221 can be a V-shaped groove, an arc-shaped groove, or a square groove.

[0057] It can be understood that the first needle groove 221 is provided on the side of the adsorbing member 220 close to the base 100. When the second power member 240 drives the adsorbing member 220 to rotate above the base 100, the first needle groove 221 faces downward. When the second power member drives the adsorbing member 220 to rotate in front of the base 100, the first needle groove 221 faces backward.

[0058] It can be understood that the syringe is stored in the needle storage groove 110 in the front-back direction. When the thimble member 210 drives the thimble tube close to the adsorbing member 220 and the adsorbing member 220 adsorbs the syringe, the syringe is placed in the front-back direction. When the second power member 240 drives the adsorbing member 220 to rotate in front of the base 100, the syringe is placed in the up-down direction. Therefore, after the adsorbing member 220 stops working, the syringe can move along the direction of the first guiding hole.

[0059] Refer to Figures 1 - 11 , a basic embodiment of the second aspect of the present invention provides a method for automatically distributing syringes, which is applied to a syringe automatic distribution device, and includes the following steps:

[0060] Prepare materials, place the syringe into the needle storage groove 110 of the base 100, and install the syringe positioning member 330 on the base 100;

[0061] Pick up the syringe. The second power member 240 drives the adsorbing member 220 to rotate above the base 100. The first power member 230 drives the thimble member 210 to move upward from bottom to top. The upper end of the thimble member 210 drives the syringe to move upward together, so that the syringe approaches the adsorbing member 220. The syringe abuts against the first needle groove 221. The adsorbing member 220 starts to work, and the adsorbing member 220 adsorbs the syringe in the first needle groove 221;

[0062] Collect the syringe. The second power member 240 drives the adsorbing member 220 to rotate in front of the base 100. The third power member 310 drives the first guiding member 320 to move from back to front, so that the first guiding member 320 abuts against the adsorbing member 220. The first needle groove 221 and the second needle groove 321 cooperate to form a first guiding hole. The adsorbing member 220 stops working. The syringe is separated from the first syringe. The syringe slides along the first guiding hole of the first power member 230 to the syringe positioning member 330.

[0063] The syringe automatic distribution method according to the basic embodiment of the second aspect of the present invention stores a large number of syringes through the base 100. The thimble member 210 moves upward from bottom to top, so that the thimble member 210 passes through a large number of syringes. During the upward movement, one of the syringes just remains at the upper end of the thimble member 210, and the rest of the syringes remain in the needle storage groove 110. The second power member 240 drives the suction member 220 to rotate above the base 100. The thimble member 210 moves the syringe onto the suction member 220, and the suction member 220 adsorbs the syringe on the first needle groove 221; the second power member 240 drives the suction member 220 to rotate in front of the base 100, and the third power member 310 drives the first guide member 320 to approach the suction member 220. The first guide member 320 and the suction member 220 are in contact, so that the first needle groove 221 and the second needle groove 321 cooperate to form a first guide hole. At this time, the syringe is in the first guide hole, and the suction member 220 adsorbs the syringe, and the syringe slides along the first guide hole, so that the syringe just falls on the syringe positioning member 330; the whole process of picking up and collecting the syringe does not require manual operation, and can process multiple syringes at the same time, effectively improving production efficiency; during the process of picking up and collecting the syringe, there is no need for human hands to directly contact the syringe, ensuring the safety of the staff.

[0064] In some embodiments, the thimble member 210 includes a plurality of thimble feet 211, and the thimble feet 211 pass through the corresponding through holes. The plurality of thimble feet 211 are arranged in the vertical direction. The first power member 230 drives the thimble member 210 to move upward, and can drive a plurality of thimble feet 211 to move at the same time, so that each thimble foot 211 can pick up one of the syringes.

[0065] In some embodiments, a third needle groove 2111 is provided at the upper end of the thimble foot 211, and the third needle groove 2111 is used to cooperate with the syringe. The outer shape of the third needle groove 2111 just matches the syringe. During the upward stroke of the thimble foot 211, the upper end of the thimble foot 211 will pass through the needle storage groove 110 storing a large number of syringes. During this stroke, only one of the syringes can be installed on the third needle groove 2111, and the rest of the syringes remain in the needle storage groove 110, ensuring that each thimble foot 211 picks up only one syringe.

[0066] In some embodiments, a first inclined surface 2112 and a second inclined surface 2113 are respectively provided at the left and right ends of the first needle groove 221, and the first inclined surface 2112 and the second inclined surface 2113 are used to separate the redundant syringes from the thimble member 210. Only one of the syringes can be installed on the third needle groove 2111, and the rest of the syringes slide down along the first inclined surface 2112 and the second inclined surface 2113, further ensuring that each thimble foot 211 picks up only one syringe.

[0067] In some embodiments, in the needle storage groove 110 on the base 100, a guiding block 111 protruding upward is provided between two adjacent through holes. After the needle tube is placed in the needle storage groove 110, the needle tube slides along the edge of the guiding block 111, enabling the needle tube to slide into the through hole. Moreover, when the needle tube slides along the guiding block 111 to both sides, it can ensure that the needle tube is placed in the front-back direction, which is beneficial for the ejector member 210 to pick up the needle tube.

[0068] In some embodiments, the adsorbing member 220 is provided with a negative pressure fan, and the negative pressure fan is used to adsorb or release the needle tube. Each first needle groove 221 is provided with an air suction port, and the air suction port is communicated with the negative pressure fan. After the negative pressure fan is turned on, a negative pressure is formed at the air suction port, enabling the needle tube to be adsorbed on the first needle groove 221. After the negative pressure fan is turned off, the adsorbing member 220 releases the needle tube. The needle tube can be quickly transferred through the negative pressure fan.

[0069] In some embodiments, the adsorbing member 220 is provided with an electromagnet, and the electromagnet is used to make the adsorbing member 220 magnetic. An electromagnet is a device that generates electromagnetic force when energized. When the electromagnet is energized, the adsorbing member 220 has magnetic force, enabling the adsorbing member 220 to adsorb the needle tube; when the electromagnet is de-energized, the adsorbing member 220 is demagnetized, and the needle tube can be separated from the adsorbing member 220.

[0070] It can be understood that the adsorbing member 220 is made of soft iron or silicon steel, and soft iron and silicon steel demagnetize relatively quickly, which is beneficial to improving work efficiency.

[0071] In some embodiments, one of the ejector member 210 and the base 100 is provided with a first guiding rod 212, and the other is provided with a first guiding hole that cooperates with the first guiding rod 212. The ejector member 210 moves along the first guiding rod 212, enabling the ejector member 210 to move in a specified direction, ensuring that the needle tube can be transported into the first needle groove 221.

[0072] In some embodiments, it further includes a second guiding member 340. The second guiding member 340 is provided with a fourth needle groove 341. The second guiding member 340 is disposed in front of the base 100. The third power member 310 drives the first guiding member 320 to approach the second guiding member 340, so that the second needle groove 321 and the fourth needle groove 341 cooperate to form a second guiding hole, and the second guiding hole is disposed in the extending direction of the first guiding hole. The second guiding member 340 is a fixed structure. When the second power member 240 drives the adsorbing member 220 to rotate to the front of the base 100, the first needle groove 221 on the adsorbing member 220 and the fourth needle groove 341 on the second guiding member 340 just face the same direction. The third power member 310 drives the first guiding member 320 to approach the adsorbing member 220. The first needle groove 221 and the second needle groove 321 form a first guiding hole, and the second needle groove 321 and the fourth needle groove 341 form a second guiding hole. The needle tube can slide along the first guiding hole and the second guiding hole and fall directly onto the needle tube positioning member 330, improving the accuracy of needle tube picking.

[0073] In some embodiments, it further includes a dispensing mechanism 400, and the dispensing mechanism 400 includes:

[0074] A clamping member 410 is disposed on the base 100, and the clamping member 410 is used for clamping the syringe positioning member 330;

[0075] A fourth power member 420 is disposed on the base 100, and the fourth power member 420 is used for driving the clamping member 410 to move in the front - rear direction.

[0076] In this setting, the syringe positioning member 330 is detachably installed on the clamping member 410. The fourth power member 420 drives the clamping member 410, so that the syringe positioning member 330 moves in the front - rear direction. Using the fourth power member 420 to drive the clamping member 410 to move can effectively control the moving distance of the syringe positioning member 330, so that the syringe mounting hole of the syringe positioning member 330 can be aligned with the guiding hole.

[0077] It can be understood that a locking bolt is provided on the clamping member 410. After the syringe positioning member 330 is installed on the clamping member 410, the syringe positioning member 330 is fixed by the locking bolt.

[0078] It can be understood that a first clamping jaw and a second clamping jaw are respectively arranged at the left and right ends of the clamping member 410, and the first clamping jaw and the second clamping jaw are respectively used for clamping the left and right ends of the syringe positioning member 330.

[0079] It can be understood that the fourth power member 420 can be a telescopic motor or a telescopic cylinder.

[0080] In some embodiments, the syringe positioning member 330 is provided with a plurality of syringe mounting holes, and the syringe mounting holes are arranged in the extending direction of the first guiding hole.

[0081] In some embodiments, the syringe mounting holes are arranged in an array in the front - rear and left - right directions. The positions of the syringe mounting holes refer to the positions of the nine - needle injection needles, and a plurality of needle hole arrays are arranged in the left - right direction.

[0082] In some embodiments, the inner diameter of the first guiding hole is larger than the inner diameter of the syringe mounting hole. So that the syringe can accurately enter the syringe mounting hole without being blocked.

[0083] In some embodiments, one of the base 100 and the first guiding member 320 is provided with a second guiding rod 321, and the other is provided with a second guiding hole that cooperates with the second guiding rod 321. So that the first guiding member 320 can move in a specified direction, ensuring that the first guiding member 320 stably fits with the adsorbing member 220, and the first needle slot 221 and the second needle slot 321 can be accurately installed.
