Description

Technical Field

[0001] This invention relates to the field of automation, specifically to a needle lifting and winding machine. Background Technology

[0002] A lifting needle is an intradermal needle that is fixed intradermally or subcutaneously for an extended period to achieve the effects of acupuncture. There are two existing types of lifting needles: thumbtack-shaped and grain-shaped. The thumbtack-shaped lifting needle has a looped handle, a needle body approximately 0.3 cm long, and the needle body is perpendicular to the handle. The grain-shaped lifting needle has a grain-shaped handle, a needle body approximately 1 cm long, and the needle body is in a straight line with the handle.

[0003] The current processing of lifting needles is all done manually, especially for thumbtack-type lifting needle handles, which are made by manually winding the needle body around a fixture. This manual processing method is not only inefficient, but also results in inconsistent winding sizes and difficulty in quality control. Summary of the Invention

[0004] The purpose of this invention is to provide a needle-lifting and winding machine that enables automatic bending and winding during needle lifting processing, effectively improving efficiency while ensuring processing quality.

[0006] Preferably, the needle feeding assembly includes a mounting frame, a needle feeding wheel, a needle feeding plate, and a needle feeding motor fixed on the mounting frame. The needle feeding motor is connected to the needle feeding wheel via a belt to drive the needle feeding wheel to rotate. The surface of the needle feeding wheel is provided with multiple arc-shaped grooves for accommodating needles. The needle feeding plate is installed at an angle, and the lower end of the needle feeding plate is attached to the needle feeding wheel, so that the needles stacked in the needle feeding plate enter the arc-shaped grooves one by one.

The end of the winding shaft is inserted into the positioning block. An inlet groove communicating with the winding shaft is opened on the side of the positioning block, and a slot is opened on the end face of the winding shaft. When the slot of the winding shaft is opposite to the inlet groove, one end of the needle enters the slot from the inlet groove, and as the winding shaft rotates, the other end of the needle winds around the outer wall of the winding shaft.

Detailed Implementation

[0016] The technical solutions of 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.

[0017] This invention provides a needle-lifting and winding machine that automatically bends, winds, and loads needles onto a plate. Its structure is as follows: Figures 1-3As shown, the device includes a cabinet 1, a first turntable 2 and a second turntable 3 mounted on the cabinet, a needle assembly 4, a pre-bending assembly 5, a secondary bending assembly 6 and a cutting assembly 7 arranged around the first turntable, and a pusher assembly 8 that pushes the needle body from the first turntable into the second turntable at the cutting assembly. Multiple winding assemblies 9 are evenly spaced on the surface of the second turntable, and a drive assembly 10 that drives the winding assemblies to rotate and wind is also provided on the second turntable. A plate loading and unloading mechanism 11 is also fixed on the cabinet on the side of the second turntable to realize the loading and unloading of the needle after winding.

[0018] The first and second turntables are used to switch between processing stations. The rotation of the turntables is controlled by a drive motor at the bottom in conjunction with a gear structure. During processing, a mounting plate is set on top of the turntable to accommodate some processing components. This mounting plate does not rotate with the turntable. Its function is to install some processing components, such as cutting components and pushing components, which are mounted on the mounting plate of the first turntable. The drive components are mounted on the mounting plate of the second turntable.

[0019] The first turntable has multiple carriers 12 for loading needles at equal intervals on its surface. The carrier has a V-groove 121 on its surface to limit the needles after they are placed, so as to prevent the needles from shifting during rotation. At the same time, a platform structure 122 extends from the outer end face of the carrier, which can work with the pressure block to press the needles down from above when bending.

[0020] The first turntable primarily handles needle feeding and bending, then pushes the bent needles onto a winding assembly on the second turntable for winding processing, before unloading. The needle feeding is achieved through a needle feeding assembly, the structure of which is as follows: Figure 4 As shown, the device includes a mounting frame 41, an upper needle wheel 42, an upper needle plate 43, and an upper needle motor 44. The upper needle wheel is fixed on the mounting frame and connected to the upper needle motor via a belt. The upper needle motor drives the upper needle wheel to rotate. The surface of the upper needle wheel is provided with multiple arc-shaped grooves 45 for accommodating needles. The upper needle plate is inclined on the mounting frame, with its lower end attached to the upper needle wheel. The needles are stacked on the upper needle plate and roll downwards into the arc-shaped grooves of the upper needle wheel. To increase the rolling speed of the needles in the upper needle plate, an electromagnet 46 is provided below the upper needle plate. The electromagnet's attraction causes the upper needle plate to vibrate, thereby accelerating the rolling speed of the needles. In addition, to prevent too many needles from getting stuck in the arc-shaped grooves, a needle-blocking plate 47 is provided at the feeding point of the upper needle plate. At the same time, a needle-removing block 48 is provided at the upper needle wheel. A certain gap is left between the lower part of the needle-blocking plate and the lower needle plate to ensure that only one needle rolls out of the gap at a time. The needle-removing block is attached to the surface of the upper needle wheel to ensure that only one needle enters the arc-shaped groove at a time.

[0021] The bending of one end of the needle body is initially achieved through a pre-bending assembly, followed by a secondary bending assembly for final shaping. The structure of the pre-bending assembly is as follows: Figure 5As shown, the system includes a second mounting bracket 51, a pressing cylinder 52, a pressing pin block 53, a bending block 54, a pre-pressing block 55, and a pre-pressing cylinder 56. The pressing cylinder is fixed to the top of the second mounting bracket, and a connecting seat 57 is fixed to the telescopic end of the pressing cylinder. The pressing pin block is slidably mounted on the connecting seat, and the bending block is fixedly mounted on the connecting seat. The pre-pressing cylinder is fixed to a support platform on the side of the second mounting bracket. The pre-pressing block is connected to the telescopic end of the pre-pressing cylinder, and the pre-pressing block is directly opposite the load on the first turntable. During pre-bending, the pressure cylinder moves downward, and the pressure pin block first contacts the carrier and presses down on the needle body on the platform structure of the carrier. As the pressure cylinder continues to move downward, the bending block contacts the needle body extending out of the carrier and bends it downward. Then, the pre-pressure cylinder drives the pre-pressure block to move forward, bending the downward-bent needle body forward to form a similar vertical bending structure. In the pre-bending assembly, the pressure pin block is used to press the needle body, which effectively avoids the needle body rebounding during bending and ensures the bending dimensions.

[0022] The secondary bending assembly achieves secondary bending and shaping of the needle body after pre-bending. Its structure is similar to that of the pre-bending assembly, as detailed below. Figure 6 As shown, it includes a third mounting bracket 61, a second pressing cylinder 62 fixed above the third mounting bracket, a second pressing pin block 63 fixed to the telescopic end of the second pressing cylinder, a second bending cylinder 64 fixed to the side platform of the third mounting bracket, and a second bending block 65 installed at the front end of the second bending cylinder. The second pressing pin block presses the needle body from above to prevent arching or displacement during bending, while the second bending block performs secondary bending and shaping from the side to ensure that the overall bending angle meets the requirements.

[0023] After one end of the needle body is bent, it needs to be pushed by the pusher assembly into the winding assembly on the second turntable to wind the other end of the needle body. At the same time, the excess length of the needle body needs to be removed by the cutting assembly to avoid the tail being exposed. The structure of the pusher assembly is shown in the appendix. Figure 2 It includes a pusher cylinder 81 and a pusher rod 82. The pusher rod is directed towards the carrier, and the pusher cylinder pushes the entire assembly inside the carrier forward, so that the bent end enters the winding assembly. The structure of the cutting assembly is shown in the attached diagram. Figure 2 It includes a cutting cylinder 71 and a cutter 72 fixed to the telescopic end of the cutting cylinder. The cutting cylinder is fixed to the mounting plate above the first turntable by the fourth mounting bracket 73. The cutter is located directly above the carrier. The cutting needle body is lowered by the cutting cylinder controller. The cut excess needle body is located on the carrier and rotated to the next station for unloading by the waste assembly 13.

[0024] The waste assembly includes a pneumatic clamp 131, a transverse module 132, and a waste hopper 133. The pneumatic clamp is fixed on the mounting plate above the first turntable in conjunction with the transverse module. The waste hopper is located below the first turntable. The pneumatic clamp picks up excess needles from the carrier and sends them into the waste hopper. This assembly is designed to ensure that there are no needles on the carrier when it re-enters the needle loading assembly.

[0025] After bending, the entire assembly enters the winding assembly to begin the winding operation. Multiple winding assemblies are evenly spaced on the surface of the second turntable to achieve continuous processing. Their structure is as follows: Figures 7-8 As shown, the device includes a fixed bracket 91, a rotating shaft 92, a positioning block 93, and a winding shaft 94. The fixed bracket is mounted on the second turntable. The rotating shaft, in conjunction with a bearing, is inserted into the fixed bracket. The upper end of the rotating shaft passes through the fixed bracket and is fitted with a mating head 95. The lower end of the rotating shaft passes through the fixed bracket and is connected to the winding shaft via a coupling. The positioning block is mounted on the bottom surface of the fixed bracket. The end of the winding shaft is inserted into the positioning block. The side of the positioning block has an inlet groove 96 that connects to the winding shaft. The end face of the winding shaft also has a groove 97. When the groove of the winding shaft is opposite to the inlet groove, the bent end of the needle can enter the groove from the inlet groove. By driving the winding shaft to rotate, the other end of the needle can be wound around the outer wall of the winding shaft. To ensure that the needle enters the inlet groove smoothly, a guide block 98 with a flared opening is provided at the entrance of the inlet groove on the side of the positioning hole to guide the needle into the flared opening of the guide block.

[0026] The winding shaft is driven to rotate by a rotating shaft, which is connected to the drive assembly via a female connector at its upper end to achieve linkage. The drive assembly has the following structure: Figure 3 As shown, the assembly includes a mounting column 101, a downward cylinder 102 fixed on the mounting column, and a slider connected to the end of the downward cylinder that cooperates with a slide rail on the side wall of the mounting column to achieve up-and-down sliding. A winding motor 103 is fixed on the slider, and a docking head 104 is assembled on the rotating shaft of the winding motor. When the winding assembly rotates to below the winding motor, the downward cylinder drives the winding motor to descend, so that the docking head cooperates with the docking female head. This enables the winding motor to drive the rotating shaft to rotate, thereby driving the winding shaft to rotate and achieving winding processing.

[0027] The coiled needle is directly loaded onto a plate via a loading and unloading mechanism, the structure of which is as follows: Figure 9 As shown, it includes a storage mechanism 14, a loading mechanism 15, and a conveying and unloading mechanism 16. The storage mechanism is located on the side of the loading mechanism and is used to store empty needle plates. The needle plates are pushed into the loading mechanism one by one from below. The loading mechanism sends the needle plates to the bottom of the winding assembly to realize the insertion of the needles one by one. Then the needle plates with the needles inserted are pushed into the conveying and unloading mechanism for unloading.

[0028] The structure of the needle plate storage mechanism is as follows: Figure 10 As shown, the device has a mounting base 141, a storage hopper 142 fixed to one side of the mounting base, and a pusher cylinder 143 fixed to the other side of the mounting base. The storage hopper is formed by two U-shaped groove plates arranged opposite each other, and multiple needle plates are stacked inside the storage hopper. The storage hopper has a transverse through slot 144 at the bottom. The telescopic end of the pusher cylinder is equipped with a pusher plate. The pusher cylinder drives the pusher plate to extend, so that the end of the pusher plate inserts into the slot, pushing the bottom needle plate out of the storage hopper and into the needle plate feeding mechanism.

[0029] The structure of the needle plate feeding mechanism is as follows: Figure 11 As shown, it has a feeding linear module 151, a lifting module 152, and a needle plate holder 153. The needle plate holder is mounted on the slider of the feeding linear module through the lifting module, and can synchronously move back and forth and lift up and down. Under the control of the feeding linear module, the needle plate holder can switch between two positions. When extended, it is located directly below the winding assembly to realize the feeding of the needle body (i.e., the needle body is inserted into the needle plate). When retracted, it is located between the conveying feeding mechanism and the storage hopper, so that the needle plate pushed out by the pusher plate enters the needle plate holder. At the same time, the needle plate already loaded on the needle plate holder is pushed to the conveying feeding mechanism for feeding. The conveying feeding mechanism includes a conveyor belt 161 and a drive motor 162 for controlling the movement of the conveyor belt.

[0030] The needle-lifting and winding machine of this invention uses two sets of turntables for different processing steps. The first turntable performs the pre-processing of feeding and bending around its perimeter, while the second turntable performs the winding process. A detachable mating head is used to connect and disconnect the motor and the winding assembly shaft. This method enables one-to-many continuous processing, with feeding and unloading not affecting each other, greatly improving processing efficiency. For the winding process, the winding shaft is used with a specific slot to achieve feeding and processing simultaneously. The simplified structure not only ensures processing efficiency but also ensures winding accuracy, preventing inconsistencies in size. The entire device can automatically perform needle bending and winding processing, as well as automatic loading and unloading, eliminating a series of manual interventions and improving efficiency and overall quality.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
