Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a device for effectively identifying and marking the dense and sparse ends of a spring. Background Technique

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. The dense and sparse ends of a spring have different abilities to absorb impacts. The sparse end can help absorb the initial impact, while the dense end is responsible for providing stronger support and restoring force. Correctly identifying the dense and sparse ends of a spring is crucial for ensuring that the spring can work according to the designed requirements, which has a direct impact on the performance, durability, and safety of the product. Identifying and marking the dense and sparse ends of a spring can ensure that the spring can be assembled in the correct direction, thereby exerting the best performance.

[0003] The existing device with the publication number of CN213792914U discloses a device for effectively identifying and marking the dense and sparse ends of a spring. A vibrating disk and a conveying track are arranged on one side of a rotating platform, and a turntable, a detection component, an upending component, a marking component, and a drying component are arranged on the rotating platform. The utility model can sequentially complete the processes of automatic feeding of the spring, automatic identification of the dense and sparse ends, repositioning for the reverse end, automatic marking on the sparse end, automatic drying, and automatic discharging into a material box. However, when the dense and sparse ends of the spring are arranged incorrectly, it needs to be turned around, and this is set at each fixed position, which is a waste of resources. Summary of the Utility Model

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a device for effectively identifying and marking the dense and sparse ends of a spring, including the main body 1 of the identification and marking device. A support plate 2 is provided on the main body 1 of the identification and marking device. The outer ring of the upper end of the support plate 2 is rotationally clamped with a rotating ring plate 4. An external transmission tooth groove 401 is integrally provided on the outer ring of the rotating ring plate 4. A feeding station 5 is provided at the upper end of the support plate 2. A servo motor 11 is installed at the position below the feeding station 5. A rotating transmission gear 1101 that meshes with the external transmission tooth groove 401 is rotatably installed at the upper end of the servo motor 11. This structure can perform feeding treatment on the spring at the feeding station 5. The servo motor 11 for the rotating ring plate 4 can be hidden at the bottom of the feeding station 5, which is convenient for the rotation and maintenance of the rotating ring plate 4. Support seats 10 are evenly spaced at the upper end of the rotating ring plate 4. An adjusting transmission gear 1001 is rotatably installed in the support seat 10. A spring positioning seat 6 is fixed at the upper end of the adjusting transmission gear 1001. A spring dense and sparse end marking mechanism 3 and a spring dense and sparse end detection mechanism 9 are installed at the upper end of the support plate 2. The spring dense and sparse end marking mechanism 3 and the feeding station 5 are on opposite sides. The spring dense and sparse end detection mechanism 9 is located between the spring dense and sparse end marking mechanism 3 and the feeding station 5. This structure enables the spring to pass through the spring dense and sparse end detection mechanism 9 and the spring dense and sparse end marking mechanism 3 in sequence after feeding, so that the spring can be adjusted after the dense and sparse ends are detected and identified, and then marked. The position on the other side between the spring dense and sparse end marking mechanism 3 and the feeding station 5 can be used for discharging the marked spring. Both the spring dense and sparse end marking mechanism 3 and the spring dense and sparse end detection mechanism 9 are arranged in an L shape. A laser marker 301 is installed at the bottom of the spring dense and sparse end marking mechanism 3. A vision detector 901 and a supplementary light 902 are installed at the bottom of the spring dense and sparse end detection mechanism 9. The laser marker 301 and the vision detector 901 respectively correspond to the spring positioning seat 6. This structure can fix the spring dense and sparse end marking mechanism 3 and the spring dense and sparse end detection mechanism 9 on the support plate 2. A hydraulic drive cylinder 8 is also provided on the side of the support plate 2 at the side position of the spring dense and sparse end detection mechanism 9. A fixing frame 7 is screwed and fixed on the side of the support plate 2. The fixing frame 7 is screwed and fixed to the fixed end of the hydraulic drive cylinder 8. This structure can stably install the hydraulic drive cylinder 8 relative to the support plate 2 under the positioning of the fixing frame 7, so that the hydraulic drive cylinder 8 drives the adjusting drive gear 802 to move. When the adjusting drive gear 802 is engaged with the adjusting transmission gear 1001 after being inserted into the support seat 10, the adjusting drive gear 802 can drive the adjusting transmission gear 1001 to rotate under the drive of the motor. The adjusting transmission gear 1001 rotates the spring positioning seat 6 relative to the support seat 10. By rotating 180 degrees to reverse the position of the spring positioning seat 6, the position of the spring dense and sparse ends is adjusted to conform to the marking position. The movable end of the hydraulic drive cylinder 8 is connected with a U-shaped fixing piece 801. An adjusting drive gear 802 corresponding to the position of the adjusting transmission gear 1001 is rotatably installed in the U-shaped fixing piece 801. The spring positioning seat 6 is arranged above the support seat 10,Moreover, a clamping plate 601 for spring positioning is installed at the upper end of the spring positioning seat 6. This structure can limit the spring on the spring positioning seat 6 through the clamping plate 601, prevent the movement of the clamping plate 601, and keep the spring in an uncompressed state, so as to detect the dense and sparse ends of the spring.

[0018] Working principle: When using the marking device for effectively identifying the dense and sparse ends of the spring, first, the spring is fed from the feeding station 5. The spring is clamped on the spring positioning seat 6 through the clamping plate 601. The clamping plate 601 is adjusted according to the size of the spring positioning seat 6 to keep the spring in an uncompressed state. The servo motor 11 drives the rotating transmission gear 1101 to rotate under the positioning of the support plate 2. The rotating transmission gear 1101 drives the rotating ring plate 4 to rotate through the engagement with the outer transmission tooth groove 401. The support plate 2 is used for the rotational positioning of the rotating ring plate 4, so that the spring positioning seat 6 passes through the spring dense and sparse end detection mechanism 9 and the spring dense and sparse end marking mechanism 3 in turn during the rotation. The spring dense and sparse end detection mechanism 9 detects the dense and sparse ends of the spring through the vision detector 901. The supplementary light 902 is used for lighting processing to assist the detection of the vision detector 901. If the positions of the dense and sparse ends of the spring conform to the marking positions of the spring dense and sparse end marking mechanism 3, the spring positioning seat 6 does not need to rotate. If the positions of the dense and sparse ends of the spring do not conform to the marking positions of the spring dense and sparse end marking mechanism 3, the hydraulic driving cylinder 8 is started. The hydraulic driving cylinder 8 drives the U-shaped fixing member 801 to drive the adjusting driving gear 802 to move under the positioning of the fixing frame 7, so that the adjusting driving gear 802 is engaged with the support seat 10. The adjusting driving gear 802 rotates under the drive of the motor to make the adjusting transmission gear 1001 rotate, so that the spring positioning seat 6 rotates 180 degrees under the support of the support seat 10 to reverse the dense and sparse ends of the spring. After the position of the spring positioning seat 6 is adjusted, the hydraulic driving cylinder 8 drives the adjusting driving gear 802 to return to its original position. Then, the spring dense and sparse end marking mechanism 3 performs dense and sparse end marking processing on the spring through the laser marker 301, realizing the efficient production of the main body 1 of the identification marking device, and thus completing a series of operations.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
