[0021] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 、 2, 3, 4, 5, 6 show a specific embodiment of the automatic conveying and processing machine for puncture needles of the present invention. This embodiment includes a robot 0, a loading mechanism 1, a grinding mechanism 2, a laser marking mechanism 3, a visual inspection mechanism 4, a length detection mechanism 5, and a blanking mechanism 6. The loading mechanism 1, the grinding mechanism 2, the laser marking mechanism 3, the visual inspection mechanism 4, the length detection mechanism 5, and the blanking mechanism 6 are arranged around the robot 0, and the robot 0 is used to take and place the puncture needles; the loading mechanism 1 is provided with a placement seat 11 for placing the puncture needles and a loading and pushing mechanism 12 for pushing the placement seat 11. The loading and pushing mechanism 12 pushes the placement seat 11 loaded with puncture needles to the output end for the robot 0 to take the material, and pushes the empty placement seat 11 to the input end for the robot 0 to take the material. Puncture needle loading; the blanking mechanism 6 includes a finished product blanking seat 61 and a waste blanking channel 62. The finished puncture needle is placed on the finished product blanking seat 61 by the robot 0, and the waste puncture needle is placed on the waste blanking channel 62 by the robot 0; the grinding mechanism 2 includes a first clamping mold 21, a translation component 22, a rotating component 23, a coarse grinding wheel group 24 and a fine grinding wheel group 25. The puncture needle is placed on the first clamping mold 21 by the robot 0 for clamping. The first clamping mold 21 is translated by the translation component 22 and successively approaches the coarse grinding wheel group 24 and the fine grinding wheel group 25 to perform coarse grinding and fine grinding of the puncture needle needle head. The rotating component 23 is connected to the first clamping mold 2 1 is used to drive the puncture needle to rotate and adjust the contact position between the needle head and the coarse grinding wheel group 24 and the fine grinding wheel group 25; the length detection mechanism 5 includes a first placement mold 51 and a resistance sensor 52. The puncture needle that has been polished at the polishing mechanism 2 is placed on the first placement mold 51 by the robot 0. The puncture needle is pressed against the resistance sensor 52. The resistance value is used to judge whether the puncture needle meets the qualified length. The qualified puncture needle is further transported by the robot 0 to the laser marking mechanism 3, and the unqualified puncture needle is transported by the robot 0 to the waste discharge channel 62; the laser marking mechanism 3 includes a second clamping mold 31 and a laser marker 32. The length detection mechanism The qualified puncture needles at structure 5 are vertically placed by the robot 0 on the second clamping mold 31, and the laser marker 32 laser marks the puncture needles on the side of the second clamping mold 31; the visual inspection mechanism 4 includes a third clamping mold 41 and a visual inspection camera 42. The puncture needles that have completed laser marking at the laser marking mechanism 3 are vertically placed on the third clamping mold 41 by the robot 0, and the visual inspection camera 42 detects whether the laser marking on the puncture needles is qualified on the side of the third clamping mold 41. The qualified puncture needles are transported by the robot 0 to the finished product discharge seat 61, and the unqualified puncture needles are transported by the robot 0 to the waste discharge channel 62.

[0023] When the present invention is in use, the puncture needle has completed the processing and forming of the needle body and the upper end handle in the previous sequence. The puncture needle is placed on the placement seat 11 of the feeding mechanism 1 by the previous conveying mechanism or manipulator and other structures, and is pushed to the output end by the feeding pushing mechanism 12.

[0024] The robot 0 in the present invention clamps a puncture needle from the output end and places it on the first clamping mold 21 of the grinding mechanism 2. The translation component 22 drives the first clamping mold 21 with the needle head of the puncture needle to first reach the coarse grinding wheel group 24 to rough grind the needle head. The rotating component 23 periodically rotates the puncture needle so that the needle head can be effectively polished throughout a circle. After the grinding at the coarse grinding wheel group 24 is completed, the translation component 22 drives the first clamping mold 21 with the needle head of the puncture needle to the fine grinding wheel group 25, and cooperates with the periodic work of the rotating component 23 to complete the grinding and removal of burrs on the puncture needle. After that, the first clamping mold 21 is reset, and the robot 0 clamps the puncture needle and transports it to the length detection mechanism 5.

[0025] The puncture needle is placed on the first placement mold 51, and then the first placement mold 51 is moved toward the resistance sensor 52 by a rated distance, so that the puncture needle presses against the resistance sensor 52. The resistance value detected by the resistance sensor 52 corresponds to the strength of the puncture needle's resistance, so that the resistance value is used to judge whether the puncture needle is of the standard length. If it is too long or too short, there will be a corresponding numerical deviation of the resistance value, so that it can be judged that the puncture needle length may be deviated due to the previous processing, or the puncture needle after being polished at the polishing mechanism 2 does not meet the length standard. After the first placement mold 51 is reset, if the puncture needle is detected to be qualified, the robot 0 clamps the puncture needle and conveys it to the laser marking mechanism 3; if the puncture needle is detected to be unqualified, the robot 0 clamps the puncture needle and conveys it to the waste discharge channel 62 for output.

[0026] The second clamping mold 31 of the laser marking mechanism 3 provides vertical positioning for the puncture needle. A laser marker 32 on the side marks the needle. This laser marker 32 can be implemented using existing, mature equipment. Marking is accomplished by moving the laser marker 32 up and down. After marking, the robot 0 grasps the puncture needle and transports it to the visual inspection mechanism 4.

[0027] The third clamping mold 41 of the visual inspection mechanism 4 is used for vertical positioning of the puncture needle, and the visual inspection camera 42 on the side is used to detect the marking on the needle body. The visual inspection camera 42 here can be implemented by mature equipment in the existing technology, and the displacement of the visual inspection camera 42 is used to detect whether the marking on the needle body is accurate; qualified puncture needles are transported by the robot 0 to the finished product discharge seat 61 for output, and unqualified puncture needles are transported by the robot 0 to the waste discharge channel 62 for output.

[0028] At this point, the processing and inspection of the entire processing line are completed. During this process, when the puncture needle is processed at the polishing mechanism 2 or the laser marking mechanism 3, the processing time will be longer. The robot 0 can transport the puncture needle to other workstations during this period.

[0029] As an improved specific implementation method, the polishing mechanism 2 and the laser marking mechanism 3 are each provided with two groups, each forming two processing stations.

[0030] like Figure 1 As shown, by setting up two processing stations, the polishing mechanism 2 and the laser marking mechanism 3, two groups of puncture needles can be processed at the same time. During the processing of the puncture needles at the two groups of polishing mechanisms 2 and the laser marking mechanisms 3, the robot 0 can pick up and transport the puncture needles back and forth and to different stations by relying on the time difference, thereby improving the processing efficiency.

[0031] As an improved specific implementation method, the manipulator 0 is provided with two groups of grippers 01, and the two groups of grippers 01 are rotatably arranged on the manipulator 0, and the orientation of the two groups of grippers 01 is vertically arranged, so that when the puncture needle clamped by one group of grippers 01 is in a vertical clamping state, the puncture needle clamped by the other group of grippers 01 is in a horizontal clamping state.

[0032] like Figure 1 、 6 As shown, by setting up two sets of grippers 01, the efficiency of puncture needle transportation is further improved. For example, when the puncture needle at one workstation is processed and one gripper 01 of the robot 0 happens to carry the puncture needle to be placed, the empty gripper 01 can take away the original puncture needle and the other gripper 01 can place the next puncture needle. Alternatively, when puncture needles need to be transported at different workstations, the grippers 01 at the two workstations can take them and transport them accordingly, thereby improving the overall transportation efficiency.

[0033] As an improved specific embodiment, the first clamping mold 21 and the rotating assembly 23 are both arranged on a mounting base 26, and the mounting base 26 is arranged on the translation assembly 22. The rotating assembly 23 includes a first rotating motor 231 and a transmission belt 232. The transmission belt 232 connects the first rotating motor 231 and the first clamping mold 21 for transmission. A feeding clamp group 27 is also provided on the mounting base 26 corresponding to the first clamping mold 21. The feeding clamp group 27 includes a feeding cylinder 271, a clamping cylinder 272 and a feeding clamp 273. The puncture needle is sent to the feeding clamp 273 by the robot 0 and is started by the clamping cylinder 272 to clamp the puncture needle. The feeding cylinder 271 drives the clamping cylinder 272 and the feeding clamp 273 to move relative to the first clamping mold 21, and the puncture needle is sent to the first clamping mold 21 for clamping. After polishing is completed, the puncture needle is reset by the feeding clamp group 27 for the robot 0 to take away.

[0034] like Figure 1 、 2As shown, the robot 0 clamps the puncture needle to the front of the feeding clamp group 27, and then the clamping cylinder 272 drives the feeding claw 273 to close and clamp the handle of the puncture needle. Then the robot 0 leaves, and the feeding cylinder 271 drives the puncture needle to move forward to the first clamping mold 21 to complete the clamping, and then the feeding clamp group 27 is reset; after the puncture needle is polished, the feeding clamp group 27 re-clamps and resets the puncture needle at the first clamping mold 21, so that the robot 0 can take it away. Relying on the setting of the mounting seat 26, the first clamping mold 21, the rotating assembly 23, and the feeding clamp group 27 are set together, and the relative positions are kept consistent, which is convenient for the adjustment, transfer and rotation of the puncture needle; the rotating assembly 23 is specifically set as a first rotating motor 231 and a transmission belt 232, a pulley is set at the motor shaft of the first rotating motor 231, and a pulley is set at the first clamping mold 21. The transmission belt 232 is wound around the two, and can rotate stably, thereby adjusting the angle of the puncture needle and realizing the grinding of the needle tip.

[0035] As an improved specific embodiment, the translation assembly 22 includes front and rear rails 221, a front and rear displacement motor 222, left and right rails 223 and a left and right displacement motor 224. The mounting seat 26 can be slidably set on the left and right rails 223 and driven by the left and right displacement motor 224 to move left and right. The left and right rails 223 can be slidably set on the front and rear rails 221 and driven by the front and rear displacement motor 222 to move forward and backward.

[0036] like Figure 1 、 2 As shown, the arrangement of the front and rear rails 221 and the left and right rails 223 enables flexible horizontal displacement of the first clamping mold 21 along the X and Y axes, thereby moving the puncture needle on the first clamping mold 21 to the corresponding rough grinding wheel assembly 24 and fine grinding wheel assembly 25. The front and rear displacement motor 222 and the left and right displacement motor 224 can be accurately started and stopped under the control of the control module, thereby ensuring that the puncture needle on the first clamping mold 21 is moved to the two accurate grinding positions and reset, facilitating the completion of grinding and the alignment with the pick-and-place position of the robot arm 0.

[0037] As an improved specific embodiment, the second clamping mold 31 and the third clamping mold 41 both include a second rotary cylinder 313, a pneumatic three-jaw chuck 311 located below, and left and right clamping jaws 312 located above. The pneumatic three-jaw chuck 311 is used to clamp the lower part of the puncture needle, and the pneumatic three-jaw chuck 311 is set on the second rotary cylinder 313 for rotation adjustment, and the left and right clamping jaws 312 are used to clamp the upper part of the puncture needle.

[0038] As shown in Figures 1, 3, and 4, the puncture needle is held upright in both the laser marking mechanism 3 and the visual inspection mechanism 4, with the needle tip facing downward and the handle positioned above. The pneumatic three-jaw chuck 311 securely holds the lower portion of the needle, while the left and right clamps 312 securely hold the upper portion. During laser marking, the needle body must be rotated to ensure marking around the needle body. A second rotary cylinder 313 drives the puncture needle on the pneumatic three-jaw chuck 311 to complete the required rotation. During rotation, the left and right clamps 312 separate, releasing their grip on the upper portion of the needle and ensuring optimal rotational adjustment. Similarly, during visual inspection, the second rotary cylinder 313 drives the puncture needle on the pneumatic three-jaw chuck 311 to complete the required rotation, allowing for visual inspection of the needle body's periphery. During rotation, the left and right clamps 312 separate, ensuring optimal rotational adjustment. The upper and lower clamping states maintain the stable realization of laser marking and visual inspection, and can be rotated to meet the needs of marking and inspection for one circle.

[0039] As an improved specific embodiment, the first placement mold 51 includes a base 511 and a pushing cylinder 510. The base 511 can be slidably arranged between the resistance sensor 52 and the pushing cylinder 510. A vertical plate 512 is arranged on the base 511 and a through groove 513 for the puncture needle to pass through is arranged on the vertical plate 512. The puncture needle is placed on the base 511 and the needle body passes through the through groove 513 toward the resistance sensor 52. The pushing cylinder 510 has a push plate 5101, which contacts the puncture needle to push the puncture needle and the base 511 toward the resistance sensor 52.

[0040] like Figure 1 、 4 As shown, the puncture needle is placed horizontally, and its handle is placed on the base 511. The needle body passes through the through slot 513 of the vertical plate 512 toward the resistance sensor 52, and the handle is against the vertical plate 512. The push plate 5101 on the pushing cylinder 510 is stably pressed against the handle to push the puncture needle together with the base 511 toward the resistance sensor 52 for a rated distance, so that the puncture needle contacts the resistance sensor 52 to generate a resistance value to determine whether the length is qualified; overall, the stable placement and stable pushing of the puncture needle are guaranteed, so that the detection result is accurate.

[0041] As an improved specific embodiment, the loading mechanism 1 also includes sliding grooves 13 arranged in parallel on the left and right, and the head and tail ends of the two sliding grooves 13 are passed through on the left and right for the placement seats 11 to be transported in a circular manner thereon, and the placement seats 11 are arranged in rows on the two sliding grooves 13; the first sliding groove 13 is provided with a loading pushing mechanism 12 at the input end to push the placement seat 11 carrying the puncture needle to the output end, and the second sliding groove 13 is provided with a transfer pushing mechanism 14 on the side of the input end to push the empty placement seat 11 toward the first sliding groove 13; the second sliding groove 13 is provided with a loading pushing mechanism 12 at the output end to push the empty placement seat 11 toward the input end, and the first sliding groove 13 is provided with a transfer pushing mechanism 14 at the output end to push the empty placement seat 11 toward the second sliding groove 13.

[0042] like Figure 1 、 5 As shown, the right side is the first sliding groove 13 for input, and the left side is the second sliding groove 13 for output. The placement seat 11 carrying the puncture needle is pushed toward the output end by the right sliding groove 13. The loading and pushing mechanism 12 is a pushing cylinder, which is provided with a push plate to push the placement seat 11 toward the output end. The manipulator 0 clamps the puncture needle at the output end and takes away the empty placement seat 11. The transfer pushing mechanism 14 on the right side is pushed to the second sliding groove 13 on the left. The loading and pushing mechanism 12 of the second sliding groove 13 pushes the placement seat 11 back, so that the placement seat 11 is transported in a circular cycle in the two sliding grooves 13. A space for the placement seat 11 to be pushed is reserved in the overall annular sliding groove 13, and the overall transportation is orderly.

[0043] As an improved specific embodiment, the finished product unloading seat 61 includes a carrier frame 611 and a unloading pushing mechanism 612. A slot 613 for hanging the puncture needle is set on the carrier frame 611 along the conveying direction. The unloading pushing mechanism 612 is set at the input end of the carrier frame 611 to push the puncture needle to the output end.

[0044] like Figure 1 、 5 As shown, the processed puncture needle is clamped by the robot 0 to the input end of the carrier 611, the needle body is placed in the slot 613, the handle is placed on the carrier 611, and the needle body is suspended in the slot 613. The unloading pushing mechanism 612 is a pushing cylinder, which is provided with a pushing plate to push the puncture needle to the output end, and the subsequent conveying robot can take the material from the output end to complete the collection.

[0045] As an improved embodiment, the waste discharge channel 62 is configured as an inclined slide.

[0046] like Figure 1 、 5As shown, since the scrapped puncture needles need to be collected again to determine whether they can be recycled and reused, they do not need to be strictly sorted as a whole. The waste discharge channel 62 can be specifically set as an inclined slide to complete the rapid discharge of the puncture needles. A collection box can be set at the bottom of the waste discharge channel 62 to complete the collection of the puncture needles, thereby improving the transportation efficiency and well controlling the component cost.
