[0002] Injection is a commonly used medical technique. In medical cosmetology, in order to ensure that the injected drug is better and more evenly absorbed, multi-needle needles are usually used, such as a nine-needle injection needle.

[0003] The existing nine-needle injection needle needs to go through the steps of selecting needle tubes, transporting needle tubes, installing needle tubes, fixing needle tubes, etc. Each step is achieved through a different structure. After completing each process, it needs to be transferred to another structure to complete the next process. The degree of automation is low, and the needle tube is easily offset during the transfer process, affecting the assembly accuracy of the needle tube

[0004] Moreover, it is difficult to control the angle of the injection needle blade after the needle is installed, so that the angles of each blade of the injection needle are facing different directions. When in use, due to the different angles of the incision blades, the force angles of each needle tube on the user are different, which makes some needle tubes easy to insert into the human body, while some needle tubes are difficult to insert into the human body, which increases the pain of the human body and is not conducive to use.

The seventh power member 620 is used to drive the glue dispenser 610 to approach or move away from the pinhole 511 .

[0070] The needle moving mechanism 100, the steering mechanism 200, the positioning mechanism 300, and the needle retracting mechanism 500 are arranged in sequence from top to bottom.

[0071] The basic embodiment of the second aspect of the present invention provides a method for using a medical injection needle automatic needle loading system, comprising the following steps:

[0072] The adsorbing member 110 adsorbs the needle tube, and adsorbs the needle tube to the first needle groove 111, so that the first needle groove 111 is arranged in the up-down direction;

[0073] The second power member 320 drives the cutting block 310 to approach the lower part of the needle tube, so that the guide surface 311 of the cutting block 310 is directly below the needle tube;

[0074] The adsorbent 110 reduces the suction force, and the needle tube falls in the vertical direction due to gravity, and the lower end of the needle tube abuts the guide surface 311, and at least part of the structure of the needle tube is located on the adsorbent 110;

[0075] The first power member 210 drives the first adjustment plate 220 and the second adjustment plate 230 to move closer to or farther from each other, so that the outer wall of the first adjustment rod 221 and the outer wall of the second adjustment rod 231 can abut against the needle tube, thereby causing the needle tube to rotate around its own axis, so that the first adjustment rod 221 abuts against the needle tube and continues to move, causing the needle tube to rotate around its own axis until the blade surface of the needle tube matches the guide surface 311 of the cutting block 310;

[0076] The first power member 210 drives the first adjustment plate 220 away from the needle tube, and the adsorption member 110 increases the suction force to fix the needle tube on the adsorption member 110, and the first adjustment plate 220 and the cutting block 310 are reset;

[0077] The fourth power member 520 drives the needle seat 510 to approach the needle tube from bottom to top, so that the needle tube is inserted into the needle hole 511;

[0078] The adsorption member 110 stops working, and the fourth power member 520 drives the needle seat 510 away from the adsorption member 110 from top to bottom;

[0079] The sixth power member 144 drives the adsorption member 110 away from the needle seat 510 , and the seventh power member 620 drives the glue dispenser 610 to move downward, injecting glue into the connection between the needle tube and the needle seat 510 to fix the needle tube on the needle seat 510 .

[0080] According to the basic embodiment of the first aspect of the present invention, an automatic needle loading system for medical injection needles is provided. The adsorption member 110 of the needle transport mechanism 100 is used to arrange the needle tube in the up-down direction. The needle tube can be driven by gravity to fall vertically. When the needle tube falls, the lower end of the needle tube abuts against the cutting block 310. Only when the blade surface of the needle tube matches the guide surface 311 of the cutting block 310, the needle tube is at the lowest end and cannot rotate relative to itself. When the blade surface of the needle tube does not match the guide angle of the cutting block 310, the needle tube is in a relatively upper position. At the same time, the needle tube can rotate relative to its own axis. When the first power member 210 of the steering mechanism 200 drives the first adjustment plate 220 to approach the needle tube, the first adjustment rod 221 can abut against the needle tube. Due to the friction between the first adjustment rod 221 and the needle tube, the needle tube can rotate relative to itself. When the needle tube rotates to a certain angle, the needle tube continues to fall, and the direction of the blade surface of the needle tube changes. The blade surface of the needle tube is changed, and finally the angle of the guide angle of the cutting block 310 is matched, so that the blade surface of each needle tube can face the same direction; the adsorption member 110 adsorbs the needle tube on the first needle groove 111, and when the suction force of the adsorption member 110 is reduced, the needle tube can slide along the first needle groove 111; a plurality of needle tubes are arranged at the same time, so that a plurality of first adjustment rods 221 can drive a plurality of needle tubes to rotate at the same time, thereby improving work efficiency; the fourth power member 520 drives the needle seat 510 to move in the up and down and front and back directions, so that the needle seat 510 can enter the device in the front and back directions, and then the needle tube is inserted into the needle seat 510 in the up and down directions; the seventh power member 620 drives the glue dispenser 610 to approach the needle hole 511, and injects glue into the connection between the needle tube and the needle hole 511, so that the needle tube is fixed on the needle seat 510; through the automatic needle installation system, the needle tube can be automatically installed on the needle seat 510 and the blade surface of the needle tube can face the same direction.

[0081] It can be understood that the first power member 210 is a lead screw or a telescopic cylinder, and the second power member 320 is a lead screw or a telescopic cylinder.

[0082] In some embodiments, the steering mechanism 200 further includes a second positioning plate 230, and the second positioning plate 230 is provided with a second positioning rod 231. The first power member 210 is used to drive the first positioning plate 220 and the second positioning plate 230 to move closer to or farther from each other, so that the outer wall of the first positioning rod 221 and the outer wall of the second positioning rod 231 can abut against the needle tube, thereby causing the needle tube to rotate around its own axis. The first positioning plate 220 and the second positioning plate 230 are close to each other, and the first positioning plate 220 and the second positioning plate 230 are respectively located on both sides of the needle tube, so that the first positioning plate 220 and the second positioning plate 230 abut against both sides of the needle tube, thereby increasing the friction between the needle tube and the positioning rod in the horizontal direction, so that the needle tube can rotate effectively, and preventing the needle tube from being too smooth or thin to rotate.

[0083] In some embodiments, a chamfer 221a is provided at the top of the first adjustment rod 221. The chamfer 221a provided at the top of the first adjustment rod 221 can reduce the diameter of the top of the first adjustment rod 221, so that when the first adjustment rod 221 passes through the needle tube, the first adjustment rod 221 is not blocked, so that the first adjustment rod 221 can be inserted into the needle tube; the second adjustment rod 231 is the same.

[0084] In some embodiments, the first adjustment rod 221 is a cylindrical structure, and the first adjustment rod 221 and the needle tube are perpendicular to each other. The first adjustment rod 221 and the needle tube are both cylindrical structures, and there is point-to-point contact between the two, which prevents the first adjustment rod 221 and the needle tube from having too much friction in the vertical direction, so that the needle tube cannot fall onto the cutting block 310 in the up and down direction.

[0085] In some embodiments, the first power member 210 is a bidirectional screw, which can simultaneously drive the first adjustment plate 220 and the second adjustment plate 230 to move closer to or away from each other. A bidirectional screw is a left-handed screw, in which one part of the screw thread is left-handed and the other part is right-handed. When the screw rotates in one direction, the two nuts on the thread separate or move closer to each other, and when it rotates in the opposite direction, the two nuts move closer or separate. The bidirectional screw drives the first adjustment plate 220 and the second adjustment plate 230 at the same time, so that the movement speeds of the first adjustment plate 220 and the second adjustment plate 230 are the same and the directions are opposite, and then the movement speeds of the first adjustment rod 221 and the second adjustment rod 231 are also the same, which is conducive to the first adjustment rod 221 and the second adjustment plate 230 driving the needle tube to rotate; the screw has high transmission efficiency and accurate positioning, which is conducive to the needle tube rotating to the corresponding angle.

[0086] In some embodiments, the first adjustment rod 221 is rotatably disposed on the first adjustment plate 220. The first adjustment rod 221 can rotate around its own axis. When the needle tube falls, the first adjustment rod 221 rotates with the needle tube so that the lower end of the needle tube can maintain abutment with the cutting block 310. The second adjustment rod 231 is the same as the first adjustment rod 221.

[0087] In some embodiments, a friction layer is provided on the surface of the first adjustment rod 221 and / or the second adjustment rod 231, and the friction layer is used to abut the needle tube. The friction layer is made of rubber-based friction material, paper-based friction material, resin-based friction material, carbon fiber friction material or semi-metal friction material.

[0088] In some embodiments, a locking mechanism 400 is further included, and the locking mechanism 400 includes:

[0089] Pressing plate 410;

[0090] The third power member 420 is used to drive the pressing plate 410 to approach the adsorption member 110 from the back to the front, so that the needle tube is fixed on the adsorption member 110.

[0091] Under this setting, when the cutting block 310 and the first adjusting rod 221 are away from the needle tube, the needle tube may fall vertically because the gravity is greater than the suction force of the adsorbent 110, and the needle tube may abut against the adsorbent 110 through the pressure plate 410, so that the needle tube is fixed on the adsorbent 110.

[0092] In some embodiments, the pressing plate 410 is provided with a protrusion 411, which is suitable for the first needle groove 111, and the protrusion 411 can abut the needle tube to fix the needle tube on the adsorbent 110. The protrusion 411 can penetrate into the first needle groove 111, so that the protrusion 411 abuts against the needle tube, and the protrusion 411 is in full contact with the needle tube, thereby improving the stability of the needle tube.

[0093] In some embodiments, the protrusion 411 is made of an elastic material such as rubber or silicone. The protrusion 411 squeezes the needle tube, and the protrusion 411 is deformed by the force, so that the needle tube is fixed on the adsorption component 110 .

[0094] In some embodiments, the needle moving mechanism 100 further includes a guide block 120, and the guide block 120 is provided with a guide hole 121, and the guide hole 121 is suitable for the diameter of the needle tube, so that the needle tube is arranged in the up and down direction. The inner diameter of the first needle groove 111 is larger than the diameter of the needle tube, and the needle tube can pass through the guide hole 121 to perform other operations, thereby preventing the needle tube from being offset during the rotation process, which affects the installation of the needle tube.

[0095] In some embodiments, the circular edge formed at the lower end of the guide hole 121 is inscribed in the circular edge formed by the first needle groove 111. It can be understood that, viewed from the front-to-back or left-to-right direction, the lower end of the guide hole 121 and the first needle groove 111 are not in the same plane, but, viewed from the up-down direction, the lower end of the guide hole 121 and the first needle groove 111 are inscribed, so that the needle tube can move along the first needle groove 111 and along the guide hole 121, and the needle tube can maintain a straight line motion in the up-down direction without changing direction, thereby preventing the needle tube from deviating.

[0096] In some embodiments, the upper end of the guide hole 121 is adapted to the diameter of the first needle groove 111, and the lower end of the guide hole 121 is adapted to the diameter of the needle tube, and the guide hole 121 gradually decreases from top to bottom. The inner diameter of the first needle groove 111 is larger than the diameter of the needle tube, and the needle tube can pass through the guide hole 121 to perform other operations, preventing the needle tube from being offset during the rotation process, which affects the installation of the needle tube.

[0097] In some embodiments, a needle retracting mechanism 500 is further included, and the needle retracting mechanism 500 includes a needle seat 510 and a fourth power member 520. The needle seat 510 is provided with a needle hole 511, and the fourth power member 520 is used to drive the needle seat 510 to approach the needle tube so that the needle tube is inserted into the needle seat 510. The fourth power member 520 drives the needle seat 510 to move in the up-down and front-to-back directions, so that the needle seat 510 can enter the device in the front-to-back direction, and then the needle tube is inserted into the needle seat 510 in the up-down direction.

[0098] It is understandable that the fourth power member 520 is a combination of two guide rails, or a combination of two telescopic cylinders.

[0099] In some embodiments, a glue dispensing mechanism 600 is further included, and the glue dispensing mechanism 600 includes a glue dispenser 610 and a seventh power member 620. The glue dispenser 610 is disposed directly above the positioning mechanism 300, and the seventh power member 620 is used to drive the glue dispenser 610 to approach or move away from the needle hole 511. The glue dispenser 610 is driven by the seventh power member 620 to approach the needle hole 511, and glue is injected into the connection between the needle tube and the needle hole 511, so that the needle tube is fixed on the needle seat 510.

[0100] In some embodiments, the glue dispenser 610 is provided with an alignment plate 611, which is arranged in the left and right direction, and is used to drive the needle tubes to move downward so that multiple needle tubes are at the same height. When the seventh power member 620 drives the glue dispenser 610 to press down, it will drive the pressing plate 410 to move downward, driving the needle tubes to move downward at the same time, ensuring that the needle tubes are at the same height.

[0101] In some embodiments, a detection mechanism is further included, and the detection mechanism includes an infrared detector, which is used to detect whether the needle tube is in place. The infrared detector can emit infrared rays. When the needle tube is fully matched with the cutting block 310, the needle tube is at the lowest point. The infrared rays illuminate the position of the lowest point, and whether the needle tube is in place is determined by whether the needle tube is at this position.

[0102] In some embodiments, the adsorbent 110 is provided with a negative pressure hole, which is provided in the first needle slot 111 and connected to a negative pressure fan. The negative pressure hole is fixed in the first needle slot 111 by the negative pressure fan, so that the adsorbent 110 can transfer the needle tube easily.

[0103] In some embodiments, the adsorption member 110 is provided with an electromagnet, and the adsorption effect of the adsorption member 110 is controlled by controlling the on and off of power or adjusting the magnitude of the power.

[0104] In some embodiments, the needle moving mechanism 100 further includes:

[0105] The base 130 is provided with a needle storage slot for storing needle tubes. The base 130 is provided with a plurality of through holes, which are arranged at the lower end of the needle storage slot;

[0106] The picking arm 140 includes a ejector member 141, an adsorption member 110, a fifth power member 143 and a sixth power member 144. The ejector member 141 passes through the through hole. The adsorption member 110 is provided with a plurality of first needle grooves 111. The first needle grooves 111 correspond to the through holes one by one. The adsorption member 110 is rotatably provided on the base 130. The sixth power member 144 drives the adsorption member 110 to rotate around the base 130. The sixth power member 144 is used to drive the adsorption member 110 to rotate to the top of the base 130. The fifth power member 143 drives the ejector member 141 to approach the adsorption member 110 from bottom to top, so that the needle tube on the base 130 approaches the adsorption member 110, and then the needle tube is adsorbed on the first needle groove 111.

[0107] Under this arrangement, a large number of needle tubes are stored through the base 130, and the ejector member 141 moves from bottom to top, so that the ejector member 141 passes through a large number of needle tubes. During the rising process, one of the needle tubes just stays at the upper end of the ejector member 141, and the remaining needle tubes stay in the needle storage groove. The sixth power member 144 drives the adsorption member 110 to rotate to the top of the base 130, and the ejector member 141 moves the needle tube to the adsorption member 110, and the adsorption member 110 adsorbs the needle tube on the first needle groove 111; the adsorption member 110 is driven by the fifth power member 143 to rotate to the front of the base 130, so that the needle tubes are arranged in the up and down direction; the entire process of picking up and collecting the needle tubes does not require manual operation, and can handle multiple needle tubes at the same time, effectively improving production efficiency and ensuring the safety of staff.

[0108] It can be understood that the first needle groove 111 is a concave structure, so that the needle tube can extend into the first needle groove 111, and the first needle groove 111 can be a V-shaped groove, an arc groove or a square groove.

[0109] It can be understood that the first needle groove 111 is arranged on a side of the adsorption component 110 close to the base 130. When the second power component 320 drives the adsorption component 110 to rotate above the base 130, the first needle groove 111 faces downward. When the second power component drives the adsorption component 110 to rotate to the front of the base 130, the first needle groove 111 faces backward.

[0110] In some embodiments, the ejector member 141 includes a plurality of ejector pins, which pass through corresponding through holes. The plurality of ejector pins are arranged in the up-down direction, and the first power member 210 drives the ejector member 141 to move upward, and can simultaneously drive a plurality of ejector pins to move, so that each ejector pin can pick up one of the needle tubes.

[0111] In some embodiments, the upper end of the ejector pin is provided with a third needle groove, and the third needle groove is used to cooperate with the needle tube. The shape of the third needle groove is just suitable for the needle tube. When the ejector pin moves from bottom to top, the upper end of the ejector pin will pass through the needle storage groove where a large number of needle tubes are stored. During this stroke, only one of the needle tubes can be installed on the third needle groove, and the rest of the needle tubes remain in the needle storage groove, ensuring that each ejector pin only picks up one needle tube.

[0112] In some embodiments, the left and right ends of the first needle groove 111 are respectively provided with a first bevel and a second bevel, and the first bevel and the second bevel are used to separate the redundant needle tubes from the ejector pin 141. Only one of the needle tubes can be installed on the third needle groove, and the remaining needle tubes slide down along the first bevel and the second bevel, further ensuring that each ejector pin only picks up one needle tube.
