DETAILED DESCRIPTION

[0016] 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 the embodiments. 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.

[0017] The present invention provides a needle lifting and winding machine, which realizes the automatic bending, winding and plate loading operations of the needle lifting, and its structure is as follows: Figures 1 to 3As shown, it includes a cabinet 1, a first turntable 2 and a second turntable 3 installed on the cabinet, an upper needle assembly 4 arranged around the first turntable, a pre-bending assembly 5, a secondary bending assembly 6 and a cutting assembly 7, and a pushing assembly 8 for pushing the needle body from the first turntable to the second turntable is also provided at the cutting assembly. A plurality of winding assemblies 9 are evenly spaced on the surface of the second turntable, and a driving assembly 10 for driving the winding assembly to rotate and circle 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 plate loading and unloading of the needle after winding.

[0018] The first turntable and the second turntable are used to realize the processing switching between various workstations. The rotation of the turntable is controlled by the driving motor at the bottom and the gear structure. In order to realize the installation of some processing components during processing, a mounting plate is set above the turntable. The mounting plate does not rotate with the rotation of the turntable. Its function is to install some processing components, such as the cutting component and the pushing component. They are installed on the mounting plate of the first turntable, and the driving component is installed on the mounting plate of the second turntable.

[0019] A plurality of carriers 12 for loading needles are arranged at equal intervals on the surface of the first turntable. The surface of the carrier has a V-shaped groove 121 for limiting the position of the needle after placement to prevent the needle from shifting during rotation. At the same time, a platform structure 122 extends from the outer end surface of the carrier to cooperate with the pressure block to press the needle from above when bending.

[0020] The first rotating disk mainly realizes the loading and bending of the needle body, and pushes the bent needle body to the winding assembly on the second rotating disk for winding processing, and then loads the plate and unloads the material. The loading of the needle body is realized by the upper needle assembly, and its structure is as follows: Figure 4 As shown, it 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 through a belt. The upper needle motor drives the upper needle wheel to rotate. The surface of the upper needle wheel is provided with a plurality of arc grooves 45 for accommodating needle bodies. The upper needle plate is tilted on the mounting frame, and its lower end is in contact with the upper needle wheel. The needle bodies are stacked on the upper needle plate and roll downward into the arc groove of the upper needle wheel. In order to increase the rolling speed of the needle bodies in the upper needle plate, an electromagnet 46 is arranged below the upper needle plate. The upper needle plate is vibrated by the adsorption of the electromagnet, thereby accelerating the rolling speed of the needle bodies. In addition, in order to prevent too many needle bodies from being stuck in the arc groove, a needle stopper plate 47 is also provided at the unloading position of the upper needle plate, and a needle picking block 48 is also provided at the upper needle wheel. A certain gap is left between the bottom of the needle stopper plate and the lower needle plate to ensure that only one needle rolls out of the gap at a time, and the needle picking block is in contact with the surface of the upper needle wheel to ensure that only one needle enters the arc groove at a time.

[0021] The bending of one end of the needle body is performed by a pre-bending component for preliminary bending, and then the bending is finalized by a secondary bending component. The pre-bending component structure is as follows: Figure 5As shown, it includes a second mounting frame 51, a downward pressure cylinder 52, a pressure needle block 53, a bending block 54, a pre-pressing block 55 and a pre-pressing cylinder 56. The downward pressure cylinder is fixed on the top of the second mounting frame, and the telescopic end of the downward pressure cylinder is fixed with a connecting seat 57. The pressure needle block is slidably assembled on the connecting seat, and the bending block is fixedly assembled on the connecting seat. The pre-pressing cylinder is fixed on the support platform on the side of the second mounting frame, and the pre-pressing block is connected to the telescopic end of the pre-pressing cylinder, and the pre-pressing block is directly opposite to the load on the first turntable. During pre-bending, the downward pressure cylinder moves downward, and the needle pressure block first contacts the carrier and presses the needle body on the platform structure of the carrier. As the downward 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, and bends the downward bent needle body forward to form a similar vertical bending structure. In the pre-bending assembly, a needle pressure block is used to press the needle body, which effectively avoids rebound of the needle body during bending and ensures the size of the bending.

[0022] The secondary bending assembly realizes the secondary bending of the needle body after pre-bending. Its structure is similar to that of the pre-bending assembly. Figure 6 As shown, it includes a third mounting frame 61, a second pressing cylinder 62 fixed above the third mounting frame, a second needle pressing block 63 fixed on the telescopic end of the second pressing cylinder, a second bending cylinder 64 fixed on the side platform of the third mounting frame, and a second bending block 65 installed at the front end of the second bending cylinder. The second needle pressing block presses the needle body from above to avoid arching or displacement during bending, and the second bending block realizes 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 to the winding assembly on the second turntable by the pushing assembly to wind the other end of the needle body. At the same time, the excess length of the needle body needs to be cut off by the cutting assembly to avoid the tail leakage. The structure of the pushing assembly is shown in the attached Figure 2 , including a push cylinder 81 and a push rod 82. The push rod is aimed at the carrier, and the push cylinder is used to push the entire body in the carrier forward so that the bent end enters the coil assembly. The structure of the cutting assembly is shown in the attached Figure 2 , including a cutting cylinder 71, a cutter 72 fixed on the telescopic end of the cutting cylinder, the cutting cylinder is fixed to the mounting plate above the first turntable through a fourth mounting bracket 73, the cutter is located directly above the carrier, and the needle body is cut by descending through the cutting cylinder controller. The excess needle body after cutting is located on the carrier and rotates to the next station for unloading through the waste assembly 13.

[0024] The waste assembly includes a pneumatic clamp 131, a transverse movement module 132 and a waste hopper 133. The pneumatic clamp cooperates with the transverse movement module to be fixed on the mounting plate above the first turntable. The waste hopper is provided below the first turntable. The pneumatic clamp is used to clamp the excess needle bodies on the carrier and send them to the waste hopper. The setting of this assembly is to ensure that there are no needle bodies on the carrier that enters the upper needle assembly again.

[0025] After the bending, the whole enters the coil assembly and starts the coiling operation. The coil assembly is multiple and is arranged at equal intervals on the surface of the second turntable to achieve continuous processing. Its structure is as follows Figure 7-8 As shown, it includes a fixed bracket 91, a rotating shaft 92, a positioning block 93 and a winding shaft 94. The fixed bracket is assembled on the second turntable, and the rotating shaft is inserted into the fixed bracket with a matching bearing. The upper end of the rotating shaft passes through the fixed bracket and is equipped with a docking female head 95. The lower end of the rotating shaft synchronously passes through the fixed bracket and is connected to the winding shaft through a coupling. The positioning block is assembled on the bottom surface of the fixed bracket, and the end of the winding shaft is inserted into the positioning block. An introduction groove 96 connected to the winding shaft is opened on the side of the positioning block, and a notch 97 is also provided on the end surface of the winding shaft. When the notch of the winding shaft is opposite to the introduction groove, the bent end of the needle body can enter the notch from the introduction groove. By driving the winding shaft to rotate, the other end of the needle body can be wound on the outer wall of the winding shaft. In order to ensure that the needle body enters the introduction groove smoothly, a guide block 98 with a flared opening is provided at the entrance of the introduction groove on the side of the positioning hole to guide the needle body entering the flared opening of the guide block inward.

[0026] The winding shaft is driven to rotate by the rotating shaft, and the rotating shaft is connected to the driving component through the docking female head at the upper end to achieve linkage. The driving component structure is as follows Figure 3 As shown, it includes a mounting column 101, a downward cylinder 102 fixed on the mounting column, a slider connected to the end of the downward cylinder cooperates with the 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 sub-head 104 is installed on the rotating shaft of the winding motor. When the winding assembly rotates to the bottom of the winding motor, the downward cylinder drives the winding motor to descend, so that the docking sub-head cooperates with the docking female head, so that the winding motor can drive the rotating shaft to rotate, and then drive the winding shaft to rotate to achieve winding processing.

[0027] The needle body after winding is directly loaded on the plate through the loading and unloading mechanism. The structure of the loading and unloading mechanism is as follows: Fig. 9 As shown, it includes a storage mechanism 14, a loading mechanism 15, and a conveying and unloading mechanism 16, wherein the storage mechanism is located on the side of the loading mechanism, and is used to store empty needle plates, and push the needle plates one by one onto the loading mechanism from below, and the needle plates are sent to the bottom of the winding assembly through the loading mechanism to insert the needle bodies one by one, and then the needle plates with the inserted needle bodies are pushed into the conveying and unloading mechanism for unloading.

[0028] The needle plate storage mechanism structure is as follows Fig.10 As shown, it has a mounting base 141, a storage hopper 142 fixed on one side of the mounting base, and a pushing cylinder 143 fixed on the other side of the mounting base. The storage hopper is composed of two U-shaped groove plates arranged opposite to each other, and a plurality of needle plates are stacked in the storage hopper. A transverse slot 144 is provided below the storage hopper. A pushing plate is installed at the telescopic end of the pushing cylinder. The pushing cylinder drives the pushing plate to extend so that the end of the pushing plate is inserted into the slot, and the bottom needle plate is pushed out of the storage hopper into the needle plate loading mechanism.

[0029] The needle plate feeding mechanism structure is as follows Fig.11 As shown, there are a feeding linear module 151, a lifting module 152, and a needle plate seat 153. The needle plate seat is installed on the slider of the feeding linear module through the lifting module, and can synchronously realize forward and backward movement and up and down lifting. The needle plate seat can switch between the front and back positions under the control of the feeding linear module. The extended position is located directly below the coil assembly to realize the unloading of the needle body (that is, the needle body is inserted into the needle plate), and the retracted position is located between the conveying unloading mechanism and the storage hopper, so that the needle plate pushed out by the pushing plate just enters the needle plate seat, and at the same time, the needle plate that has been loaded on the needle plate seat is pushed to the conveying unloading mechanism for unloading. The conveying unloading 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 the present invention adopts two sets of turntables to carry out processing of different processes, wherein the first turntable realizes the front-end processing of loading and bending on all sides, while the second turntable realizes the winding processing, and a detachable docking male and female connector is used to realize the connection and separation of the motor and the rotating shaft of the winding assembly. This method can realize one-to-many continuous processing, and loading and unloading do not affect each other, which greatly improves the processing efficiency; for the winding processing, the winding shaft is matched with a specific notch to realize loading and processing, and the simplified structure not only ensures the processing efficiency, but also ensures the winding accuracy, and there will be no problem of inconsistent size. The whole equipment can automatically realize the bending and winding processing of the needle body, and at the same time realize automatic loading and unloading, eliminating a series of manual interventions and improving efficiency and overall quality.
