Description

Instant correction equipment for spring machines

The present invention relates to a correction device, in particular to an instant correction device for a spring machine.

A general spring machine is used to wind wire into a spiral spring. It mainly feeds the wire at high speed in a feeding direction and blocks the wire through two winding tools with mutually perpendicular axis lines. The wire blocked by one of the winding tools will turn and move in a curved path. The turned wire will be blocked by the other winding tool and continue to bend forward, so that the wire is wound into a spiral spring. At this time, another pitch tool moves along the extension direction perpendicular to the feeding direction to apply pressure to the coiled wire along the axial direction, so that the wire can form a spiral continuous coil. After the set number of turns are wound, it is cut off by a cutting tool to produce a spiral spring. Repeating the above steps can quickly and continuously produce a large number of spiral springs. Since the above-mentioned operation process is very fast, as long as there is a slight disturbance or interference factor, it is easy to cause the diameter or pitch of the spring to have a large tolerance problem. Therefore, it is necessary to improve the existing spring machine to ensure the quality of the spring.

Therefore, the object of the present invention is to provide a device that can make real-time corrections based on errors.

Therefore, the instant correction device of the spring machine of the present invention includes a pitch tool for adjusting the pitch of a wire, a plurality of winding tools for adjusting the diameter of the wire, and a controller for controlling the movement of the pitch tool and the winding tools. The instant correction device includes a carrier that can be movably arranged next to the spring machine, a sensing device arranged on the carrier, and an analysis device connected to the sensing device.

The sensing device includes at least one image detector disposed on the carrier and facing the spring machine, and an analysis processor connected to the at least one image detector by signal. The at least one image detector can perform image detection on the pitch or diameter of the wire and continuously obtain multiple detection results. The analysis processor can obtain a corresponding signal point based on each detection result.

The analysis device is connected to the analysis processor signal and has a built-in database for storing multiple correction data. Each correction data includes a signal point and a correction value corresponding to the signal point. The analysis device can obtain a corresponding correction value from the database according to each signal point transmitted by the analysis processor, and transmit the correction value to the controller to drive the pitch tool or at least one of the winding tools to move according to the correction value.

The effect of the present invention is that the at least one image detection machine can monitor the wire being processed in real time and continuously to detect the pitch between every two adjacent coils of the wire, or the length of the diameter of each coil, and the analysis processor can determine the corresponding signal point of each detection result based on the data input in advance. Finally, the analysis device can determine the correction value required for the signal point corresponding to the detection result based on the correction data in the database, and control the controller to drive the pitch tool or the winding tools to move accordingly, so as to achieve the effect of eliminating errors in real time. The present invention adopts a mobile design and can correspond to different types of spring machines and their controllers. In addition to being highly versatile, the controller does not need to perform calculations, thereby reducing the burden of the controller and increasing the correction speed.

Referring to Fig. 1, Fig. 2, and Fig. 3, an embodiment of the instant correction device of the spring machine of the present invention comprises a carrier 1, a sensing device 2 disposed on the carrier 1, an analysis device 3 whose signal is connected to the sensing device 2, and two backlight panels 4 disposed on the carrier 1. The carrier 1 comprises a support plate 11, four pulleys 12 pivotally disposed on the bottom surface of the support plate 11 and in rolling contact with the ground, two setting seats 13 spaced apart from each other and erected on the support plate 11, two mounting seats 14 spaced apart from each other and erected on the support plate 11, and a material receiving seat 15 disposed between the setting seats 13 and the mounting seats 14 in the horizontal direction and erected on the support plate 11. The material receiving seat 15 has a frame 151 disposed on the receiving plate 11, a seat body 152 disposed on the frame 151 to be retractable, a cylinder 153 capable of driving the seat body 152 to move up and down relative to the frame 151, and a guide rail 154 disposed on the seat body 152. The guide rail 154 has a guide section 155 extending downwardly and obliquely, and a receiving section 156 extending upwardly and obliquely toward the guide section 155. In this embodiment, the slope of the guide section 155 is greater than the slope of the receiving section 156. The sensing device 2 includes two image detectors 21 disposed on the mounting seats 13, and an analysis processor 22 connected to the image detector 21 by signal. The analysis device 3 is signal-connected to the analysis processor 22 and has a built-in database 31 storing multiple correction data. Each correction data includes a signal point and a correction value corresponding to the signal point. The backlight panels 4 are detachably mounted on the mounting seats 14.

Referring to FIG. 4, FIG. 5, and FIG. 6, the carrier 1 can move freely on the ground through the pulleys 12, so that the instant correction device can be applied to different types of spring machines 5. The spring machine 5 includes a feeding mechanism 51, a pitch tool 52, two winding tools 53, and a controller 54 for controlling the pitch tool 52 and the winding tools 53. The feeding mechanism 51 can quickly transport the wire A along a feeding direction B. The central axes of the pitch tool 52 and the winding tools 53 are approximately located on the same vertical plane. The wire A output along the feeding direction B is wound into a coil after sequentially touching the winding tools 53. The pitch tool 52 moves along a pitch direction C perpendicular to the feeding direction B to apply pressure to the wire A, thereby causing the wire A to spirally extend along the pitch direction C to form a plurality of continuous and connected coils. The pitch tool 52 includes a motor 521, a screw 522 driven by the motor 521, a connecting arm 523 disposed on the screw 522 and movable along the axial direction of the screw 522, and two pitch cutters 524 disposed on the connecting arm 523 and extending opposite to each other. The motor 521 drives the connecting arm 523 to move by directly transmitting the screw rod 522, so that the pitch knives 524 can move along the pitch direction C accurately and quickly.

Referring again to FIG. 1 , FIG. 4 , and FIG. 5 , the image detectors 21 (not shown in FIG. 4 ) face the spring machine 5 and are aligned with the wire A being wound into a coil during processing. The image detectors 21 can perform image detection on the diameter of the wire A and/or the pitch of the wire A as required, thereby continuously obtaining a plurality of detection results. The continuous results are transmitted to the analysis processor 22, and the analysis processor 22 can find out the signal point corresponding to each detection result according to the pre-set data. Then, the analysis processor 22 transmits the signal points to the analysis device 3, and the analysis device 3 finds the correction value corresponding to each signal point according to the correction data in the database 31, and finally inputs the correction value into the controller 54, so that the controller 54 can drive the pitch tool 52 in real time to adjust the pitch of the wire, and/or drive the winding tools 53 to adjust the diameter of the wire. Of course, the correction value can also be zero. In addition, the receiving section 156 is located between the guide section 155 and the spring machine 5 in the horizontal direction, and can be used to receive the wire A being processed, and the guide section 155 extends downwardly in a direction away from the spring machine 5, and can be used to guide the processed springs to move along the slope for easy collection. The backlight panels 4 can adjust the angle according to the needs to illuminate, so that the image detection machines 21 can obtain a clearer image.

In summary, the present invention uses the analysis processor 22 and the analysis device 3 to quickly calculate the required correction value, so that the controller 54 only needs to control the movement of the pitch tool 52 and the winding tools 53 according to the correction value, which greatly reduces the burden of the controller 54 and can be used for general spring machines 5 without correction functions. In addition, the design of the movable carrier, the lifting and lowering guide rails 154, and the adjustable angle of the image detectors 21 allows the present invention to be moved to different spring machines 5 as needed. It is highly versatile and can indeed achieve the purpose of the present invention.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
