[0001] The application belongs to the technical field of filament forming, and particularly relates to a filament forming system. BACKGROUND

[0002] An electronic vacuum device is a special electronic equipment, which is characterized in that a specific function is realized by utilizing electron flow in a vacuum or high-vacuum environment.

[0006] By using the above filament forming system, the unwinding mechanism releases the filament, the wire feeding mechanism conveys the filament to the wire drawing chuck after receiving the filament, the wire drawing chuck draws out the filament by a distance after clamping the filament, and the bending mechanism bends the drawn-out filament after the heating mechanism heats the filament. In this way, the ductility of the filament can be improved and the yield strength and residual stress can be reduced by heating before bending, so that the filament is conveniently bent by the bending mechanism, and the probability of rebound and the probability of being broken are reduced.

[0007] Further, the heating mechanism is arranged between the unwinding mechanism and the wire feeding mechanism.

[0008] Furthermore, it also includes a straightening mechanism, which is disposed between the unwinding mechanism and the wire feeding mechanism.

The length detector is disposed on the wire feeding mechanism and is used to detect the length of the filaments output by the wire feeding mechanism.

[0010] Furthermore, it also includes a feeding mechanism, which is located downstream of the feeding mechanism and is used to receive the product formed by the cutting mechanism.

[0011] Furthermore, it also includes a testing mechanism, which is located above the feeding mechanism and is used to test the product.

[0012] Furthermore, it also includes a handling mechanism, a finished product silo, and a waste product silo. The handling mechanism can transport qualified products from the unloading mechanism to the finished product silo, and the unloading mechanism can transport unqualified products to the waste product silo.

[0013] Furthermore, it also includes a rotating mechanism, wherein the unwinding mechanism and the wire feeding mechanism are both disposed in the rotating mechanism, and the rotating mechanism can drive the unwinding mechanism and the wire feeding mechanism to rotate around the axis of the filament on the wire feeding mechanism.

[0014] Furthermore, it also includes a pressing mechanism, which is disposed between the wire feeding mechanism and the bending mechanism, and is used to compress the filaments drawn out by the wire drawing chuck.

[0015] Furthermore, it also includes a control mechanism, which is electrically connected to the wire feeding mechanism, the wire drawing mechanism, the bending mechanism, and the heating mechanism.

[0016] In summary, the filament forming system provided in this application has at least one of the following advantages: 1.

[0026] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a filament forming system, including an unwinding mechanism 110, a filament feeding mechanism 120, a filament drawing mechanism, and a bending mechanism 130.

[0027] The unwinding mechanism 110 is used to release the filament 200, and the wire feeding mechanism 120 is located downstream of the unwinding mechanism 110 to receive and transport the filament 200. It should be noted that the unwinding mechanism 110 is a conventional mechanism; the filament 200 is wound around the unwinding mechanism 110, and the filament 200 can be released during the active or passive rotation of the unwinding mechanism 110. Initially, the leading end of the filament 200 is manually pulled to the wire feeding mechanism 120, and subsequently, the leading end of a new filament 200 can connect with the tail end of an older filament 200, achieving continuous feeding of the filament 200.

[0028] The wire drawing mechanism includes a wire drawing chuck, which is movably configured to approach or move away from the wire feeding mechanism 120, and is capable of clamping and releasing the filament 200 output by the wire feeding mechanism 120. A bending mechanism 130 is located downstream of the wire feeding mechanism 120 and is used to bend the filament 200 drawn out by the wire drawing chuck. Thus, after the wire feeding mechanism 120 delivers the filament 200 to the wire drawing chuck, the wire drawing chuck clamps the filament 200 and moves it along a preset direction (…). Figure 1 (In the left-right direction, the same below) the filament 200 is pulled out to a certain distance. Next, the filament 200 is released by the drawing chuck, and the drawn filament 200 is bent by the bending mechanism 130. After bending, the filament 200 extending from the wire feeding mechanism 120 can be cut as required to form the filament 200 product. Finally, the drawing chuck returns to its initial position and receives the filament 200 fed by the wire feeding mechanism 120 again. It should be noted that the bending mechanism 130 is a conventional mechanism and will not be described in detail here.

[0029] Furthermore, the filament forming system also includes a heating mechanism 140. The heating mechanism 140 is located downstream of the unwinding mechanism 110 and is used to heat the filament 200. Thus, for certain metal filaments 200, heating them first increases their ductility, reduces their yield strength and residual stress, facilitates bending by the bending mechanism 130, and reduces the probability of breakage during bending.

[0030] Using the aforementioned filament forming system, the unwinding mechanism 110 releases the filament 200, the feeding mechanism 120 receives the filament 200 and conveys it to the drawing chuck. The drawing chuck clamps the filament 200 and pulls it out a certain distance. The heating mechanism 140 heats the filament 200, and then the bending mechanism 130 bends the drawn filament 200. In this way, heating before bending improves the ductility of the filament 200, reduces its yield strength and residual stress, facilitates bending by the bending mechanism 130, and reduces the probability of springback and breakage.

[0031] In one embodiment, the wire feeding mechanism 120 includes a conveying drive 121 and a conveying chuck 122. The conveying drive 121 is connected to the conveying chuck 122 to drive the conveying chuck 122 to reciprocate in a preset direction, and the conveying chuck 122 can clamp and release the filament 200. Thus, the filament 200 can be conveyed to the drawing chuck via the conveying chuck 122. Optionally, the conveying drive 121 is a motor and is connected to the conveying chuck 122 via a lead screw nut; the conveying chuck 122 can be a pneumatic chuck or a servo chuck. Similarly, the structures of the wire drawing mechanism and the wire feeding mechanism 120 described above can be the same, and will not be elaborated further here.

[0032] It should be noted that after the wire drawing chuck clamps the filament 200, the conveying chuck 122 releases the filament 200 and returns to its initial position under the action of the conveying drive 121. After the wire drawing chuck pulls the filament 200 to a preset length, the conveying chuck 122 clamps the filament 200 again, and the wire drawing chuck releases the filament 200. After the bent filament 200 is cut, the wire drawing chuck returns to its initial position, and then the conveying chuck 122 continues to convey the filament 200 to the wire drawing chuck.

[0033] It should be explained that the initial position of the conveying chuck 122 refers to the position where the conveying chuck 122 clamps and acquires the filament 200, while the initial position of the drawing chuck refers to the position where the drawing chuck clamps and acquires the filament 200. These are two different positions, and the initial position of the drawing chuck is downstream of the initial position of the conveying chuck 122. Furthermore, the cyclical operation of the two chucks ensures that the filament 200 remains clamped, preventing it from falling off, improving the reliability of the system, and enabling the filament forming system to operate continuously.

[0034] In one embodiment, the filament forming system further includes a straightening mechanism 150, which is disposed between the unwinding mechanism 110 and the filament feeding mechanism 120, and is used to straighten the filament 200 released by the unwinding mechanism 110 into a straight state. It should be noted that the filament 200 is wound around the unwinding mechanism 110, so the filament 200 released by the unwinding mechanism 110 is usually in a curled state. Straightening the filament 200 into a straight state by the straightening mechanism 150 facilitates subsequent bending operations.

[0035] Furthermore, the straightening mechanism 150 includes multiple sets of thread rolling assemblies 151. These multiple sets of thread rolling assemblies 151 are arranged at intervals along a preset direction. Each set of thread rolling assemblies 151 includes multiple pressing rollers 152 and multiple guide rollers 153. The multiple pressing rollers 152 and multiple guide rollers 153 are arranged in a one-to-one correspondence, and the multiple guide rollers 153 are arranged at intervals along the preset direction, allowing the filament 200 to pass between the pressing rollers 152 and the guide rollers 153. Thus, the pressing rollers 152 and the guide rollers 153 cooperate to press the filament 200, and after passing through the multiple pressing rollers 152 and multiple guide rollers 153 arranged along the preset direction, the filament 200 is straightened. The multiple sets of thread rolling assemblies 151 further ensure that the curled filament 200 is straightened.

[0036] Furthermore, the straightening mechanism 150 also includes a mounting plate 154. Multiple sets of thread rolling assemblies 151 are spaced apart on the mounting plate 154 along a preset direction, and the pressure roller 152 and the guide roller 153 are rotatably mounted on the mounting plate 154 and located on the same side of the mounting plate 154.

[0037] Furthermore, the straightening mechanism 150 may also include a tension drive 155. The tension drive 155 is disposed on the mounting plate 154 and connected to the pressure roller 152 and / or the guide roller 153 to drive the pressure roller 152 and / or the guide roller 153 to rotate, thereby controlling the tension of the filament 200 being conveyed. Optionally, the tension drive 155 is a motor.

[0038] In some embodiments, the thread rolling assembly 151 may further include a clamping drive. The clamping drive is disposed on the mounting plate 154 and connected to the clamping roller 152 to drive the clamping roller 152 closer to and further away from the guide roller 153, thereby adjusting the distance between the clamping roller 152 and the guide roller 153 according to the size of the filament 200, improving versatility. Additionally, when the clamping drive is connected to the clamping roller 152, the tension drive 155 is connected to the guide roller 153. Optionally, the clamping drive is a pneumatic cylinder or an electric cylinder. Of course, in the foregoing embodiments, to achieve the processing of filaments 200 of different sizes, this can be achieved by replacing the clamping roller 152 and the guide roller 153 in the thread rolling assembly 151, and is not limited thereto.

[0039] In one embodiment, the heating mechanism 140 is positioned between the unwinding mechanism 110 and the wire feeding mechanism 120. This allows the heating mechanism 140 to heat the filament 200 while preventing it from interfering with the operation of the wire feeding mechanism 120 and the wire drawing mechanism. Preferably, the heating method of the heating mechanism 140 is coil heating, where the filament 200 passes between coils, and the coils are energized to heat the filament 200. Furthermore, the coil heating in the heating mechanism 140 is controlled by PID to improve temperature control accuracy. It is certain that in this embodiment, the heating mechanism 140 is positioned downstream of the straightening mechanism 150 to facilitate the passing of the straightened filament 200 through the heating coil. In other embodiments, if the requirements for heating method and temperature control accuracy are lower, the heating mechanism 140 can also heat the coil using a flame. In this case, the heating mechanism 140 can be positioned downstream of the wire feeding mechanism 120 and heat the filament 200 by spraying a flame, without affecting the operation of the wire feeding mechanism 120 and the wire drawing mechanism.

[0040] In one embodiment, the filament forming system further includes a rotating mechanism. The unwinding mechanism 110, straightening mechanism 150, heating mechanism 140, and filament feeding mechanism 120 are all disposed within the rotating mechanism. The rotating mechanism can drive the unwinding mechanism 110, straightening mechanism 150, heating mechanism 140, and filament feeding mechanism 120 to rotate around the axis of the filament 200 on the filament feeding mechanism 120, thereby adjusting the angle of the filament 200 output by the filament feeding mechanism 120, allowing the filament forming system to meet more forming requirements. Specifically, the rotating mechanism includes a rotating drive and a mounting base. The rotating drive is connected to the mounting base, and the unwinding mechanism 110, straightening mechanism 150, heating mechanism 140, and filament feeding mechanism 120 are all disposed on the mounting base to rotate under the drive of the rotating drive. Optionally, the rotating drive is a motor.

[0041] In one embodiment, the filament forming system further includes a cutting mechanism 160 and a length detector. The cutting mechanism 160 is disposed between the wire feeding mechanism 120 and the bending mechanism 130, and is used to cut the filament 200 output from the wire feeding mechanism 120, thereby cutting the bent filament 200 and completing the preparation of the filament 200 product. The length detector is disposed in the wire feeding mechanism 120 and is used to detect the length of the filament 200 output from the wire feeding mechanism 120. It is understood that the position of the cutting mechanism 160 is fixed, and the wire drawing mechanism can draw the filament 200 to a preset length according to the detection structure of the length detector. After the filament 200 is processed, the cutting mechanism 160 cuts the filament 200, completing the preparation of the filament 200 product.

[0042] Optionally, the cutting mechanism 160 may include a cutting drive and a cutter. The cutting drive is connected to the cutter to drive the cutter to reciprocate, and the cutter can cut the filament 200 during the reciprocating movement. Of course, in other embodiments, the cutter may also be a shearing component, such as a structure similar to scissors, and the cutting drive is used to drive the shearing component to perform a shearing action to cut the filament 200. In addition, in this embodiment, the length detector is preferably a grating ruler.

[0043] In one embodiment, the filament forming system further includes a clamping mechanism 170. The clamping mechanism 170 is disposed between the filament feeding mechanism 120 and the bending mechanism 130, and is used to compress the filament 200 drawn from the drawing chuck, thereby compressing the circular filament 200 into a flat shape as needed. Further, the clamping mechanism 170 includes a clamping drive, a pressure head, and a support platform. The clamping drive is connected to the pressure head to drive the pressure head towards and away from the support platform; the filament 200 can pass between the pressure head and the support platform. Optionally, the clamping drive is a cylinder or an electric cylinder. Thus, the clamping drive can drive the pressure head to press the filament 200 onto the support platform, thereby flattening the filament 200. Of course, in other embodiments, the pressure head in the clamping mechanism 170 can also be a structure similar to a chuck. In this case, there is no need to provide a support platform; the clamping drive drives the chuck to perform a clamping action to flatten the filament 200.

[0044] In one embodiment, the filament forming system further includes a feeding mechanism 181. The feeding mechanism 181 is located downstream of the filament feeding mechanism 120 and is used to receive the product formed by the cutting mechanism 160 and feed the product off. In practical applications, the feeding mechanism 181 includes a feeding drive and a conveyor belt. The feeding drive drives the conveyor belt to move, and the conveyor belt transports the product. It should be noted that the conveyor belt and the corresponding drive are conventional configurations and will not be described in detail here.

[0045] In one embodiment, the filament forming system further includes a detection mechanism 190. The detection mechanism 190 is positioned above the feeding mechanism 181 and is used to detect the products, thereby identifying defective products and facilitating subsequent classification of qualified and unqualified products. Optionally, the detection method of the detection mechanism 190 is image recognition detection. Additionally, it should be noted that in the above embodiment, the front end of the new filament 200 is connected to the tail end of the old filament 200; products with this connection point will be identified as unqualified products.

[0046] In one embodiment, the filament forming system further includes a conveying mechanism 182, a finished product hopper 183, and a waste product hopper 184. The conveying mechanism 182 can transport qualified products from the unloading mechanism 181 to the finished product hopper 183, while the unloading mechanism 181 can transport unqualified products to the waste product hopper 184. Figure 2As shown, the handling mechanism 182 is a multi-axis robot, the finished product bin 183 is located on one side of the unloading mechanism 181, and the waste bin 184 is located at the unloading end of the unloading mechanism 181.

[0047] In one embodiment, the filament forming system further includes a control mechanism. This control mechanism is electrically connected to the straightening mechanism 150, heating mechanism 140, filament feeding mechanism 120, filament drawing mechanism, bending mechanism 130, pressing mechanism 170, cutting mechanism 160, length detector, unloading mechanism 181, and conveying mechanism 182 described in the above embodiment, to achieve automatic operation of the filament forming system. In practical applications, the control mechanism includes a host computer, a PLC controller, and a touch screen that are electrically connected to each other. The PLC controller is electrically connected to each of the aforementioned mechanisms.

[0048] To facilitate understanding of the technical solution of this application, this document combines... Figure 1 and Figure 2 The process flow of the filament forming system in the above embodiments is described as follows: Initially, the operator pulls the filament 200 on the unwinding mechanism 110 through the straightening mechanism 150 and the heating mechanism 140 in sequence, and then clamps it in the conveying chuck 122 of the wire feeding mechanism 120. During the pulling process, the straightening mechanism 150 straightens the filament 200 as it passes through, and the heating mechanism 140 also heats the filament 200. Next, the conveying chuck 122 moves the filament 200 toward the drawing chuck until the filament 200 is inserted into the drawing chuck. The drawing chuck clamps the filament 200, and the conveying chuck 122 releases the filament 200 and returns to its initial position. The drawing chuck, in conjunction with the length detector, pulls the filament 200 to a preset length, and then the conveying chuck 122 continues to clamp the filament 200, while the drawing chuck releases the filament 200. Next, the bending mechanism 130 bends the filament 200, while the rotating mechanism and the clamping mechanism 170 rotate and clamp the filament 200 respectively as needed. After processing the filament 200, the cutting mechanism 160 cuts the filament 200, thus completing the product preparation. The product falls onto the unloading mechanism 181 below. When the product on the unloading mechanism 181 passes through the inspection mechanism 190, the inspection mechanism 190 inspects the product. Products that pass the inspection are transported to the finished product silo 183 by the handling mechanism 182, while products that fail the inspection are transported to the scrap silo 184 by the unloading mechanism 181.

[0049] It should be noted that if the filament 200 needs to be bent multiple times, after the drawing chuck pulls the filament 200 to a preset length and releases it, it can be controlled to return to its initial position. The drawing chuck and the conveying chuck 122 cooperate with each other to convey the filament 200 to the bending mechanism 130 in stages. Specifically, the drawing chuck first clamps the filament 200 and moves it a certain distance towards the bending mechanism 130, then the conveying chuck 122 clamps the filament 200, and the drawing chuck releases the filament 200 and returns to its initial position. Repeating this step can achieve the staged conveying of the filament 200 to the bending mechanism 130.

[0050] In summary, the filament forming system provided in this application has at least one of the following advantages: 1. Before bending, the filament 200 can be heated by the heating mechanism 140, which improves the ductility of the filament 200, reduces the yield strength and residual stress of the filament 200, facilitates the bending operation of the filament 200, and reduces the probability of the filament 200 springing back and being broken. 2. A conveying chuck 122 and a wire drawing chuck are set up so that the fine wire 200 is always held by the chuck (conveying chuck 122 or wire drawing chuck) during operation, so as to prevent the fine wire 200 from falling off, improve the reliability of system operation, and realize the continuous operation of fine wire 200 processing; 3. All mechanisms are electrically connected to the control mechanism, enabling automated operation of the filament forming system; 4. By setting a length detector, the feeding length of the filament 200 can be accurately controlled, thereby improving the processing accuracy of the filament 200.
