[0022] A marking method for an anesthetic needle, characterized by comprising the following steps:

[0023] S1: Prepare the needles, place the anesthetic needles to be marked in the needle storage bucket in the same direction;

[0024] S2: Needle arrangement: the anesthetic needles are sequentially released from the needle storage bucket of the needle storage mechanism and arranged in the needle slots on the needle transport board. The number of needles arranged on the needle transport board is 90 to 100 at a time. When the anesthetic needles are arranged into the needle transport board, the second leveling plate in the needle storage bucket performs a reciprocating leveling action to correct the position of the anesthetic needles on the needle transport board to ensure that the center of gravity of the anesthetic needles is located in the needle transport board;

[0025] S3: needle transport, the needle transport mechanism transports the anesthetic needles arranged on the needle transport plate from the needle storage bucket to the needle pushing mechanism;

[0026] S4: Pushing the needle. After the needle pushing mechanism presses the anesthetic needle arranged on the needle transporting plate, the needle pushing mechanism pushes one end of the anesthetic needle flat;

[0027] S5: Clamping and transferring. After the leveling is completed, the transport mechanism moves to one end of the anesthetic needle and clamps the anesthetic needle. After clamping the anesthetic needle, the transport mechanism retreats to move the anesthetic needle between the upper and lower needle rubbing plates.

[0028] S6: needle rubbing preparation, the lower needle rubbing plate rises and contacts the anesthetic needle clamped by the transfer mechanism, and then the upper needle rubbing plate descends and contacts the anesthetic needle. The anesthetic needle is fixed on the needle rubbing mechanism through the clamping of the lower needle rubbing plate and the upper needle rubbing plate, and the transfer mechanism is separated from the anesthetic needle;

[0029] S7: Needle rubbing: the lower needle rubbing plate is driven by the horizontal driving unit to move back and forth horizontally to rub the anesthesia needle between the upper and lower needle rubbing plates to roll back and forth for 1.5 to 2 circles;

[0030] S8: Marking. While the anesthetic needle is being rubbed by the upper and lower needle rubbing plates, the marking device works synchronously, the upper and lower needle rubbing plates are energized, and the surface of the anesthetic needle located between the upper and lower needle rubbing plates that needs to be marked is electro-corroded and turns black to produce a mark. During marking, the voltage difference between the upper and lower needle rubbing plates is 10~20V, the current intensity is 10~15A, and the marking time is 40~60S.

[0031] Working principle: first place the anesthetic needles to be marked in the needle storage mechanism. When marking is required, the needle storage mechanism evenly discharges the anesthetic needles, and then the needle transport mechanism transports them to the needle push mechanism. The needle push mechanism presses the anesthetic needles on the needle transport plate and pushes one end of the anesthetic needle flat. Then the transport mechanism sends the anesthetic needles to the needle rubbing and marking mechanism. The needle rubbing and marking mechanism rubs and marks the anesthetic needles. After marking is completed, the transport mechanism takes out the anesthetic needles and sends them to the lower hopper at the rear.

[0032] Beneficial effects: 1. Through the present invention, the fully automatic processing of needle arrangement, alignment, needle rubbing and marking in the process of anesthetic needle marking is realized, which significantly improves the marking efficiency of anesthetic needles. 2. In the process of needle arrangement, a rotating roller is set on the needle transport plate so that only one layer of anesthetic needles can be laid on the needle transport plate, so as to avoid the overlapping and mutual squeezing and deformation of the anesthetic needles during the subsequent pressure process of the anesthetic needles. In addition, the first leveling plate can be used to perform preliminary leveling on the anesthetic needles placed in the needle storage bucket, and the second leveling plate can be used to further level the needle tubes when they are placed in the needle transport plate, so that the needle transport plate is supported in the middle position of the anesthetic needles, so as to avoid the center of gravity of the anesthetic needles on the needle transport plate deviating from the needle transport plate and falling from the needle transport plate during transportation. 3. The needle pushing mechanism is set to re-align the anesthetic needles before marking, ensuring that each subsequent anesthetic needle can be marked at the correct position.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that in this solution, the number of anesthetic needles marked each time is set to 100.

[0050] like Figure 1~2 The anesthesia needle marking machine shown in the figure includes a needle storage mechanism 1000, a needle transport mechanism 2000, a needle pushing mechanism 3000, a transfer mechanism 4000 and a needle rubbing and marking mechanism 5000 arranged in sequence according to the marking process of the anesthesia needle. The needle storage mechanism is used to store the anesthesia needles to be marked, and evenly lay the anesthesia needles on the needle transport plate. When the laying of the anesthesia needles is completed, the needle transport mechanism transfers the anesthesia needles on the needle transport plate from the needle storage mechanism to the needle pushing mechanism. The needle pushing mechanism applies a thrust to one end of the anesthesia needle on the needle transport plate. The anesthesia needle is pushed flat after being stressed. After being pushed flat, the anesthesia needle is clamped by the transfer mechanism and sent to the needle rubbing and marking mechanism for needle rubbing and marking. After the marking of the anesthesia needle is completed, the transfer mechanism clamps the anesthesia needle from the needle rubbing and marking mechanism and sends it to the lower hopper 6000 of the procedure.

[0051] Specifically, Figure 3 , Figure 4 As shown, the needle storage mechanism 1000 includes a V-shaped needle storage bucket 1010, and a discharge port 1011 is provided at the lower part of the needle storage bucket for the anesthetic needle to fall horizontally. A needle blocking plate 1020 is arranged below the discharge port, and one end of the needle blocking plate is connected to a first telescopic cylinder 1030 installed on the needle storage bucket. By driving the first telescopic cylinder to extend and retract, the needle blocking plate is tilted and raised. That is, when the first telescopic cylinder is extended, the needle blocking plate extends forward and descends synchronously, and a gap appears between the needle blocking plate and the needle storage bucket for the anesthetic needle to roll out. The anesthetic needle in the needle storage bucket rolls out of the discharge port under the action of gravity and falls on the needle transport plate 1040 located below the discharge port. When the first telescopic cylinder retracts, the baffle rises, the discharge port is blocked by the needle blocking plate, and the gap between the needle blocking plate and the needle storage bucket disappears, so that the anesthetic needle cannot fall. It should be noted that the needle transport plate has a plurality of needle grooves 1041 on its surface facing the needle storage bucket. When the anesthetic needle falls, the needle transport plate moves forward slowly, and the anesthetic needle falls into the needle grooves in sequence. The needle grooves effectively restrain the anesthetic needle from rolling on the needle transport plate, preventing the anesthetic needle from rolling off the needle transport plate during transportation. At the same time, a first calibration plate 1050 is also provided in the needle storage bucket. The edge of the first calibration plate is slidably fitted against the inner wall of the needle storage bucket, and the first calibration plate is transmission-connected to a guide column 1060 slidably inserted in the side wall of the needle storage bucket to achieve sliding along the axial direction of the anesthetic needle in the needle storage bucket. In order to facilitate the adjustment of the position of the first calibration plate in the needle storage bucket to accommodate anesthetic needles of different lengths, an adjusting screw 1070 is also screwed into the side wall of the needle storage bucket. The adjusting screw extends along the axial direction of the anesthetic needle in the needle storage bucket and the end is rotatably connected to the first calibration plate. Preferably, a second telescopic cylinder 1080 is also provided on the side of the needle storage hopper, and a second leveling plate 1090 parallel to the first leveling plate is provided at the end of the second telescopic cylinder. When the needles are arranged, the second telescopic cylinder reciprocates to drive the second leveling plate to push and level one end of the anesthetic needle at the bottom of the needle storage hopper. It should be noted that in order to prevent multiple anesthetic needles from being stacked on the needle transport plate at the same time and being brought out by the needle transport plate during the needle arrangement process, a roller 1100 is provided above the needle transport plate, and the roller is connected to a first motor 1110 provided on the side for transmission. There is a gap between the roller and the surface of the needle transport plate, and the gap can only be used for the anesthetic needles that fall into the needle groove. During the needle arrangement process, the roller rotates under the drive of the first motor and brings the excess anesthetic needles on the needle transport plate back to the needle storage hopper. It should be noted that in order to facilitate the needle block plate to avoid the needle transport plate during the lifting process, the cross-section of the needle transport plate is U-shaped, and the needle block plate is arranged in the U-shaped groove of the needle transport plate. In addition, the needle blocking plate can also be arranged on both sides of the needle transport plate to achieve avoidance between the needle blocking plate and the needle transport plate.

[0052] like Figure 5As shown, the needle moving mechanism 2000 includes a first frame 2010 that plays a supporting and guiding role. Two transmission wheels 2020 are rotatably arranged at the two ends of the first frame, and a conveyor belt 2030 is wound around the transmission wheel. It should be noted that in order to improve the stability of the transmission, the transmission wheel is a gear and the conveyor belt is an adapted gear conveyor belt. A connecting block 2040 fixedly connected to the conveyor belt is arranged on the conveyor belt, and the connecting block is connected to the needle moving plate 1040. At the same time, one of the two transmission wheels is used as a driving wheel to drive and connect a second motor 2050, and a proximity switch 2060 that can sense the approaching connection block is arranged at both ends of the first frame, and the proximity switch is connected to the electrical signal of the second motor. After receiving the signal sent by the proximity switch, the second motor reverses and rotates to drive the needle moving plate to reciprocate between the needle storage mechanism and the needle pushing mechanism. In order to improve the stability of the needle moving plate during operation, at least one first slide rail 2070 is also arranged on the first frame, and the connecting block is slidably arranged on the first slide rail. It should also be noted that, for production safety, a protective cover 2080 is also provided on the first frame to irradiate the transmission wheel and the conveyor belt.

[0053] like Figure 6 As shown, after the anesthetic needle is transported to the needle pushing mechanism 3000 via the needle transport plate, the third telescopic cylinder 3020 longitudinally mounted on the second frame 3010 drives the pressing plate 3030 to move toward the needle transport plate and finally presses on the anesthetic needle on the needle transport plate. At the same time, a fourth telescopic cylinder 3040 is also horizontally mounted on the second frame, and a third leveling plate 3050 is mounted on the end of the fourth telescopic cylinder. The third leveling plate moves toward one end of the anesthetic needle on the needle transport plate under the drive of the fourth telescopic cylinder and finally abuts against the end of the anesthetic needle to push the uneven end of the anesthetic needle flat.

[0054] When the anesthetic needle is flattened again, the transport mechanism removes the anesthetic needle from the needle transport plate and sends it to the needle rubbing and marking mechanism. Figure 7As shown, the transport mechanism 4000 includes a third frame 4010, on which a fifth telescopic cylinder 4020 is arranged, and a mounting plate 4030 is installed at the front end of the fifth telescopic cylinder, on which at least one finger telescopic cylinder 4040 is arranged, and a group of clamping plates 4050 is installed on the finger telescopic cylinder. When the anesthetic needle is transported to the right place, the fifth telescopic cylinder extends, the clamping plate group extends forward to the right place, the finger telescopic cylinder drives the clamping plate group to close, and the fifth telescopic cylinder retracts immediately, and the anesthetic needle enters the needle rubbing and marking mechanism. As a preferred method, in order to facilitate the collection of the anesthetic needle after the anesthetic needle marking is completed, a second slide rail 4060 is further arranged below the third frame 4010, and the third frame is slidably arranged on the second slide rail, and a sixth telescopic cylinder 4070 that can drive the third frame to slide on the slide rail is connected to the third frame in a transmission manner. After the anesthetic needle marking is completed, the transport mechanism clamps the anesthetic needle again and transports the anesthetic needle to the rear lower hopper 6000 and then releases it, so that the anesthetic needle falls into the lower hopper.

[0055] like Figure 8As shown, the needle rubbing and marking mechanism 5000 specifically includes a lower needle rubbing device 5010 that can rub the entered anesthetic needle, an upper needle rubbing device 5020, and a marking device 5030 that performs surface electrocorrosion marking on the rubbing anesthetic needle. Specifically, the lower needle rubbing device includes a third slide rail 5011, which is perpendicular to the space of the anesthetic needle entering the upper needle rubbing device and the lower needle rubbing device. A needle rubbing platform 5012 is slidably arranged on the third slide rail, and the needle rubbing platform is transmission-connected to a horizontal driving unit 5013 that can drive it to slide on the third slide rail. At the same time, a lower needle rubbing plate 5014 is also horizontally arranged above the needle rubbing platform, and the lower needle rubbing plate is transmission-connected to a longitudinal driving unit 5015 arranged longitudinally, so that the lower needle rubbing plate has a lifting function. It should be noted that in order to ensure the stability of the lower needle rubbing plate, four guide pillars that are slidably inserted in the needle rubbing platform are connected to the four corners of the lower needle rubbing plate to constrain the lower needle rubbing plate. In this embodiment, both the horizontal driving part and the longitudinal driving part can be driven by a servo motor driving a screw or a telescopic cylinder. The upper needle rubbing device 5020 includes a fourth frame 5021, on which a seventh telescopic cylinder 5022 arranged longitudinally is installed, and the seventh telescopic cylinder is connected to an upper needle rubbing plate 5023 parallel to the lower needle rubbing plate. The marking device adopts an electro-corrosion form, and the marking device is electrically connected to the upper needle rubbing plate and the lower needle rubbing plate. When the upper needle rubbing plate and the lower needle rubbing plate rub the anesthetic needle, the marking device performs electro-corrosion marking on the surface of the anesthetic needle. Specifically, the working method of the needle rubbing marking mechanism is that after the transfer mechanism sends the anesthetic needle between the upper and lower needle rubbing devices, the longitudinal drive unit drives the lower needle rubbing plate to rise until it contacts the anesthetic needle, and then the seventh telescopic cylinder extends and drives the upper needle rubbing plate to contact the anesthetic needle. When the upper and lower needle rubbing plates are moved into place, the horizontal drive unit is activated to drive the lower needle rubbing plate to move horizontally. During the movement of the lower needle rubbing plate, the anesthetic needle is rubbed due to the friction force. During the rubbing process, the marking device is energized to perform an electro-corrosion marking operation on the surface of the anesthetic needle.

[0056] The present invention also discloses an anesthetic needle marking method implemented by an anesthetic needle marking machine. The following takes marking 100 anesthetic needles at one time as an example to provide a detailed description of the marking method.

[0057] A marking method for an anesthetic needle, comprising:

[0058] S1: Prepare the needles, place the anesthetic needles to be marked in the needle storage bucket in the same direction;

[0059] S2: Needle arrangement: the anesthetic needles are sequentially released from the needle storage bucket of the needle storage mechanism and arranged in the needle slots on the needle transport board. The number of needles arranged on the needle transport board is 90 to 100 at a time. During the arrangement of the anesthetic needles into the needle transport board, the second calibration plate performs a reciprocating pushing and leveling action to correct the position of the anesthetic needles on the needle transport board to ensure that the center of gravity of the anesthetic needles is located in the needle transport board;

[0060] S3: needle transport, the needle transport mechanism transports the anesthetic needles arranged on the needle transport plate from the needle storage bucket to the needle pushing mechanism;

[0061] S4: Pushing the needle. After the needle pushing mechanism presses the anesthetic needle arranged on the needle transporting plate, the needle pushing mechanism pushes one end of the anesthetic needle flat;

[0062] S5: Clamping and transferring. After the leveling is completed, the transport mechanism moves to one end of the anesthetic needle and clamps the anesthetic needle. After clamping the anesthetic needle, the transport mechanism retreats to move the anesthetic needle between the upper and lower needle rubbing plates.

[0063] S6: needle rubbing preparation, the lower needle rubbing plate rises and contacts the anesthetic needle clamped by the transfer mechanism, and then the upper needle rubbing plate descends and contacts the anesthetic needle. The anesthetic needle is fixed on the needle rubbing mechanism through the clamping of the lower needle rubbing plate and the upper needle rubbing mechanism, and the transfer mechanism is separated from the anesthetic needle;

[0064] S7: Needle rubbing. The lower needle rubbing plate moves back and forth horizontally under the drive of the horizontal driving part to rub the anesthetic needle located between the upper and lower needle rubbing plates to roll back and forth. It should be noted that during the marking process, the number of rolling circles of the anesthetic needle must be greater than 1 circle to prevent incomplete electro-etching of the surface of the anesthetic needle from affecting the marking quality. Preferably, the number of rolling circles of the anesthetic needle is between 1.5 and 2 circles.

[0065] S8: Marking. While the anesthetic needle is being rubbed by the upper and lower needle rubbing plates, the marking device works synchronously, the upper and lower needle rubbing plates are energized, and the surface of the anesthetic needle located between the upper and lower needle rubbing plates that needs to be marked is electro-corroded and turns black to produce a mark. During marking, the voltage difference between the upper and lower needle rubbing plates is 10~20V, the current intensity is 10~15A, and the marking time is 40~60S.

After the leveling is completed, the transport mechanism moves to one end of the anesthetic needle and clamps the anesthetic needle. After clamping the anesthetic needle, the transport mechanism retreats to move the anesthetic needle between the upper and lower needle rubbing plates. S6: needle rubbing preparation, the lower needle rubbing plate rises and contacts the anesthetic needle clamped by the transfer mechanism, and then the upper needle rubbing plate descends and contacts the anesthetic needle. The anesthetic needle is fixed on the needle rubbing mechanism through the clamping of the lower needle rubbing plate and the upper needle rubbing plate, and the transfer mechanism is separated from the anesthetic needle; S7: Needle rubbing: the lower needle rubbing plate is driven by the horizontal driving unit to move back and forth horizontally, so as to rub the anesthesia needle between the upper and lower needle rubbing plates to roll back and forth for 1.5 to 2 circles; S8: Marking. While the anesthetic needle is being rubbed by the upper and lower needle rubbing plates, the marking device works synchronously, the upper and lower needle rubbing plates are energized, and the surface of the anesthetic needle located between the upper and lower needle rubbing plates that needs to be marked is electro-corroded and turns black to produce a mark. During marking, the voltage difference between the upper and lower needle rubbing plates is 10~20V, the current intensity is 10~15A, and the marking time is 40~60S.
