The detection sensor is located in front of or behind the pair of rollers and is used to output a detection signal when the steel wire of the spring placed on the pair of rollers is detected.

[0005] This utility model has the following advantages and features:

[0006] 1.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] Please see Figures 1 to 6 According to an embodiment of the present invention, a spring orientation device includes a frame 1, a roller mechanism 2, a limiting member 3, a belt conveying mechanism 4, a lifting mechanism 5, a detection sensor 6, and an adjustable sensor bracket 7.

[0016] The roller mechanism 2 is mounted on the top of the frame 1. The roller mechanism 2 includes a pair of bases 21, two pairs of roller supports 22, and a pair of rollers 23 arranged side-by-side. The pair of bases 21 are respectively positioned on the top of the frame 1 at a distance from each other. The two pairs of roller supports 22 respectively support the pair of rollers 23, with each roller 23 rotatably supported at both ends by its corresponding pair of roller supports 22. One roller support 22 of each pair of roller supports 22 is mounted on one of the bases 21, and the other roller support 22 of each pair of roller supports 22 is mounted on the other base 21. Optionally, the pair of bases 21 are connected to the frame 1 by threaded fasteners, and the two pairs of roller supports 22 are respectively connected to the pair of bases 21 by threaded fasteners.

[0017] The limiting member 3 is located on one side of the pair of rollers 23 and is used to abut against one end of the spring 9 placed on the pair of rollers 23. The limiting member 3 is connected to the top of the frame 1.

[0018] The belt conveyor 4 is located below a pair of rollers 23, and its conveying direction is perpendicular to the axial direction of the rollers 23. The belt conveyor 4 includes a pair of belt conveyor assemblies 41, a main shaft 42, a motor 43, and a connector 44. The pair of belt conveyor assemblies 41 are spaced apart from each other. Each belt conveyor assembly 41 includes a wheel frame 410, a driving wheel 411, a driven wheel 412, and a conveyor belt 413. The driving wheel 411 and the driven wheel 412 are rotatably mounted on the wheel frame 410, and the conveyor belt 413 surrounds the driving wheel 411 and the driven wheel 412. The motor 43 is connected to the main shaft 42 to drive its rotation. The main shaft 42 is connected to the driving wheels 411 of the pair of belt conveyor assemblies to drive them to rotate synchronously. Both ends of the connector 44 are connected to the wheel frame 410 of the pair of belt conveyor assemblies. In this embodiment, the connector 44 includes a pair of connecting rods 441, and the two ends of each connecting rod 441 are respectively connected to a pair of wheel frames 410 with transmission components.

[0019] The lifting mechanism 5 supports and lifts the belt conveyor mechanism 4. After lifting, the belt conveyor mechanism 4 contacts a pair of rollers 23 and can drive the rollers 23 to rotate. The lifting mechanism 5 includes a pair of support seats 51, two pairs of support rods 52, a base plate 53, and a cylinder 54. The pair of support seats 51 are spaced apart and opposite each other to support the aforementioned connecting member 44. The top ends of one pair of support rods 52 are connected to one of the support seats 51, and the bottom ends of one pair of support rods 52 are connected to the base plate 53. The top ends of the other pair of support rods 52 are connected to the other support seat 51, and the bottom ends of the other pair of support rods 52 are connected to the base plate 53. The cylinder 54 is connected to the base plate 53 to drive the base plate 53 to rise or fall, thereby driving the belt conveyor mechanism 4 to rise or fall.

[0020] The detection sensor 6 is located in front of or behind the pair of rollers 23 to output a detection signal when it detects the steel wire of the spring 9 placed on the pair of rollers 23. The output detection signal is not limited to being sent to the controller, audio-visual prompting device, etc.

[0021] In this embodiment, the detection sensor 6 is mounted on an adjustable sensor bracket 7, allowing the relative position of the detection sensor 6 and the spring 9 placed on a pair of rollers 23 to be adjustable. The adjustable sensor bracket 7 includes a vertical rod 71, a horizontal rod 72, a first connector 73, and a second connector 74. The vertical rod 71 is fixed to the frame 1. The first connector 73 is vertically height-adjustable and mounted on the vertical rod 71. The horizontal rod 72 passes laterally through the first connector 73. The second connector 74 is movably and rotatably mounted on the horizontal rod 72, and the detection sensor 6 is mounted on the second connector 74. Optionally, the first connector 73 and the second connector 74 are U-shaped clamps that secure the rods with bolts.

[0022] In this embodiment, the detection sensor 6 is a reflective photoelectric switch.

[0023] Furthermore, the spring orientation device in this embodiment includes a controller, and the signal output terminal of the detection sensor 6 is connected to the signal input terminal of the controller. The controller is used to control the operation of the belt conveyor mechanism 4 and the lifting mechanism 5.

[0024] The working process of the spring orientation device in this embodiment is roughly as follows.

[0025] Before spring orientation is determined, cylinder 54 is activated to lift conveyor mechanism 4, bringing the conveyor belt 413 of a pair of conveyor components 41 into contact with a pair of rollers 23. The spring 9 to be tested is placed on the rollers 23 by a robotic arm or manually, with one end of the spring 9 abutting against the limiting member 3. Motor 43 is started, driving the conveyor belt 413 of the pair of conveyor components 41 to move, which in turn drives the rollers 23 and the spring 9 to rotate. When the reflective photoelectric switch outputs a detection signal, it means that the light emitted by the reflective photoelectric switch has reached the designated position of the spring 9 and is reflected by the wire, thus completing the spring orientation determination. Once orientation is successful, motor 43 is turned off, and cylinder 54 lowers conveyor mechanism 4 to its initial position, causing the conveyor belt 413 of the pair of conveyor components 41 to disengage from the rollers 23.

[0026] By adjusting the adjustable sensor bracket 7 in advance, the position of the reflective photoelectric switch relative to the spring 9 can be locked, so that the reflective photoelectric switch can only receive the reflected light and output the detection signal when the spring 9 is rotated to a predetermined angle. Compared with the manual visual inspection method, this detection method greatly improves the accuracy of the orientation result.

[0027] The spring orientation device of this utility model embodiment is applicable to most spring products, including but not limited to helical springs.

However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can extend and deduce it according to actual use without departing from the content of the present invention. Therefore, the content of the above specific embodiments should not limit the scope of protection defined by the present invention.
