Description

Technical Field

[0001] This invention belongs to the field of puncture positioning needle manufacturing technology, specifically relating to a fully automatic dispensing equipment and method for puncture positioning needles. Background Technology

[0002] Cancer incidence and mortality rates are increasing year by year. Early detection and intervention of tumors or pre-lesional nodules can effectively reduce cancer mortality. When removing nodules and tumors, small nodules are often difficult to detect. Therefore, puncture localization is needed for precise early localization of the nodules to facilitate surgical removal.

[0003] The puncture positioning needle mainly consists of a needle shaft, a needle hub, and positioning components, with the needle shaft and needle hub fixed together using UV adhesive. Currently, in the production process of puncture positioning needles, the adhesive bonding between the needle shaft and needle hub is done manually. This involves manually applying UV adhesive to the connection point using a syringe, then manually curing the adhesive with a UV light pen, thus connecting the needle shaft and needle hub. This manufacturing and assembly method, primarily relying on manual handheld equipment and with adhesive application and UV curing performed in separate steps, suffers from low efficiency, significant human error, and a low yield rate. Summary of the Invention

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1 to 8 As shown, this embodiment discloses a fully automatic dispensing device for puncture positioning needles, including a main unit 1, a platform 2, a column 3, a hydraulic feeder 4, a crossbeam 6, a UV light lamp 12, a connector 5, an adjustable angle mechanism 9, a dispensing head 10, and a glue storage tube 8.

[0046] The top surface of the main unit 1 has a platform 16, and the front of the platform has a control panel 15. The control panel 15 has operation buttons and a display screen, which are used to receive control commands and display operating parameters, respectively.

[0047] The stage 2 is set on the platform 16 and its top surface is provided with a slot 2.1; the slot 2.1 is distributed in a rectangular array, preferably in a 6×6 array, so as to realize the dispensing operation of 36 puncture positioning needles.

[0048] The main unit 1 has horizontal first tracks 14 on both sides, and two columns 3 are slidably mounted on the corresponding first tracks 14, allowing them to move back and forth. A hydraulic feeder 4 is mounted on one of the columns 3 and is used to store adhesive for dispensing.

[0049] Both columns 3 have vertical second tracks 11 on their inner sides, and the two ends of the crossbeam 6 are slidably mounted on the corresponding second tracks 11, allowing it to move up and down. A UV light lamp 12 is located at the bottom of the crossbeam 6, which can cure the puncture positioning needle on the platform 2 below.

[0050] A third track 7 is provided on the front side of the crossbeam 6. The connector 5 is slidably mounted on the third track 7, allowing it to move left and right. The connector 5 is connected to the hydraulic feeder 4 via a connecting pipe. The connector 5 is equipped with a dispensing pump and valve, both of which are inserted into the dispensing channel.

[0051] An adjustable angle mechanism 9 is mounted on the connector 5. Its function is to adjust the fixed angle of the dispensing head 10 to meet the dispensing requirements. The dispensing head 10 is mounted on the adjustable angle mechanism 9.

[0052] The glue storage tube 8 is located on top of the glue dispensing head 10 and is connected to the connector 5 through a connecting tube, thereby establishing a complete glue delivery channel.

[0053] The column 3, crossbeam 6, and connector 5 are each driven by a drive device to move along their respective directions. The "sliding installation" in this invention refers to achieving relative movement between two components through a sliding fit between a slider and a straight track. Both the slider and the track are existing technologies and will not be described in detail.

[0054] To further improve dispensing efficiency and the throughput of a single dispensing task, the connector 5, adjustable angle mechanism 9, dispensing head 10, and glue reservoir 8 are all provided in pairs, and each is matched with the other. This doubles the throughput and efficiency.

[0055] In this example, as Figure 3 As shown, the adjustable mechanism 9 includes a first connecting plate 9.1, a second connecting plate 9.2, and a hinge 20. The first connecting plate 9.1 is connected to one end of the hinge 20, and the dispensing head 10 is disposed on the first connecting plate 9.1; the second connecting plate 9.2 is connected to the other end of the hinge 20 and is disposed on the connector 5; the hinge of the hinge 20 is a tight-fit hinge. The tight-fit setting of the hinge 20 can maintain the setting angle of the dispensing head 10 by using the fastening force formed by its own fit, and when the angle needs to be adjusted, the angle of the dispensing head can be adjusted by manually bending the two connecting plates.

[0056] The movement control of column 3, crossbeam 6, and connector 5 is implemented as follows: The drive device includes gear 18, rack 17, and servo motor. Gear 18 is mounted on the spindle of the servo motor, rack 17 is mounted on the main unit 1, column 3, and crossbeam 6, and servo motor 13 is mounted on column 3, crossbeam 6, and connector 5. Rack 17 is parallel to its corresponding track and meshes with the corresponding gear 18. Driven by servo motor 13, and with the cooperation of gear 18 and rack 17, the movement of column 1, crossbeam 6, and connector 5 is achieved.

[0057] Since the stage can accommodate multiple needle holders 21, in order to quickly place and align the needle holders 21 to facilitate the dispensing operation, such as... Figure 5-8 As shown, the stage 2 has six through slots 2.15 extending to two opposite sides, each slot 2.15 corresponding to a row of slots 2.1. Each through slot 2.15 contains a first pull rod 2.5, a second pull rod 2.9, and a gear 2.4. The inner side of the first pull rod 2.5 has six first clamping parts 2.6 and first racks 2.7 at both ends. Similarly, the inner side of the second pull rod 2.9 has six second clamping parts 2.8 and second racks 2.10 at both ends. The first racks 2.7 and the second racks 2.10 on the same side are engaged with the gears 2.4 on that side. This engagement allows the first pull rods 2.5 and 2.9 to move synchronously in opposite directions, thereby changing the distance between the first clamping parts 2.6 and the second clamping parts 2.8. When the needle holder 21 needs to be inserted, the first pull rod 2.9 and the second pull rod 2.9 are driven inward, causing the first clamping part 2.6 and the second clamping part 2.8 to move synchronously in the opposite direction and leave the slot 2.1. At this time, the needle holder 21 can be normally inserted into the slot 2.1. After the needle holder 21 is in place, the first pull rod 2.9 and the second pull rod 2.9 are driven in the opposite direction. At this time, the first clamping part 2.6 and the second clamping part 2.8 move synchronously in the opposite direction and enter the slot 2.1 to clamp the needle holder 21. Through calculation, the midpoint of the line connecting the centers of the first clamping part 2.6 and the second clamping part 2.8 can be made to coincide with the center of the slot 2.1, thus achieving rapid centering.

[0058] To facilitate direct two-handed operation, one end of the first pull rod 2.5 is connected via a first connecting rod 2.2, and the other end of the second pull rod 2.9 is connected via a second connecting rod 2.3. During centering, the connecting rods enable synchronous movement of all pull rods on the same connecting rod.

[0059] To automatically clamp the needle holder 21, a first abutment portion 2.12 is provided on the outer side of a portion of the first pull rod 2.5, and a second abutment portion 2.11 is provided on the outer side of a portion of the second pull rod 2.9; a spring 2.13 is provided between the first abutment portion 2.12 and the corresponding second abutment portion 2.11. Under the action of the spring 2.13, the first pull rod 2.5 and the second pull rod 2.9 tend to move outward, thereby keeping the first clamping portion 2.6 and the second clamping portion 2.8 in a clamped state. Before inserting the needle holder 21, the first connecting rod 2.2 and the second connecting rod 2.3 need to be manually pressed, thereby moving the first clamping portion 2.6 and the second clamping portion 2.8 to both sides to ensure that the needle holder 21 is inserted into the slot 2.1.

[0060] Since there are a large number of needle holders 21, an automatic sorting method is used in this example to quickly fill the slots 2.1 in batches. The bottom of the slot 2.1 extends to the bottom surface of the stage 2, and two support protrusions 2.14 are provided at the bottom of the slot. The support protrusions 2.14 serve two purposes: one is to provide support so that the bottom of the needle holder 21 is supported on the support protrusions 2.14; the other is to achieve sorting. If the needle holder 21 is placed upside down in the slot 2.1, shaking the stage 2 will cause the needle holder 21 to fall out of the slot 2.1, thus achieving sorting. Using this principle, when loading the needle holders 21, the needle holders 21 can be scattered on the stage 2. Then, the stage 2 is shaken horizontally. If the needle holders 21 fall into the slots 2.1 with their bottoms facing down, they will remain in the slots 2.1. If they fall into the slots 2.1 with their bottoms facing up, they will fall out of the slots 2.1. This process continues until all slots 2.1 are filled with needle holders 21 before proceeding with subsequent operations. This achieves the goal of batch loading the stage 2 without the need for mechanical equipment, entirely through manual operation, which is simple and efficient.

[0061] The needle bar can be centered and fixed using the centering principle. This is achieved by using another component with the same structure as the stage. After the needle bar is placed into each slot, the movement of the pull rod aligns and fixes the needle bar in place. The stage and the component for centering and fixing the needle bar can be positioned using a positioning structure, thus aligning the needle holder 21 with the needle bar. Then, the aligned needle bar and the aligned needle holder 21 are aligned and assembled.

[0062] This invention also provides a fully automated dispensing method for a puncture positioning needle, which is performed by the aforementioned fully automated dispensing equipment and includes the following steps:

[0063] Step 1: Securely fasten the puncture needle hubs one by one into the slots 2.1 of the stage 2, and insert the needle bar into the mounting hole at the upper end of the needle hub.

[0064] Step 2: Set the dispensing angle of the dispensing head 10 to 30 degrees using the adjustable angle mechanism 9. Set the single dispensing volume and dispensing path of the dispensing head 10 using the control panel 15. The single dispensing volume is 0.01-0.05 mL.

[0065] Step 3: Start the dispensing equipment via control panel 15, so that the dispensing head 10 moves along the preset dispensing path to complete the dispensing of the puncture needle.

[0066] Step 4: Turn on the UV light lamp 12 and irradiate the puncture needle after dispensing. The UV light lamp 12 should be used for 30 seconds to cure the UV adhesive.

[0067] It should be noted that the motion control of the relevant electric components in this invention necessarily involves the input and processing of control commands, that is, the use of control buttons and controllers to achieve the above operations. However, the principle and control method are existing technologies. This invention only involves improvements to the structure and does not improve the control scheme or principle, so it will not be elaborated upon.
