Description

Technical Field

[0001] This utility model relates to a marking device for use in the automotive manufacturing industry, and particularly to a marking device for use in automotive parts production lines. Background Technology

[0002] In automobile manufacturing, marking is an important process, which is usually used to mark key data such as identification information, production date, batch number, and manufacturer code on parts.

[0003] In modern automotive parts production lines, the manufacturing of automotive parts requires high-speed mass production, making product quality process control particularly important. Each process requires strict quality control. The manual inspection and marking of workpieces is prone to misjudgment due to human subjectivity. Moreover, due to issues such as cycle time, it is impossible to add a separate marking station. The quality of workpiece production cannot be guaranteed, allowing defective products to flow into the next process, resulting in the entire product being unqualified, causing great waste of resources and increasing production costs.

[0004] Most existing engraving devices use single-head engraving or simple combinations of multiple single heads, resulting in slow engraving speed, low production efficiency, low accuracy and stability, high engraving cost when the engraving workload is large, and difficulty in ensuring the accuracy and consistency of engraving.

[0005] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] refer to Figures 1 to 2 As shown, a marking device for an automotive parts production line includes a mounting base 1, a cylinder 2, a connecting block 3, a base 4, and a sleeve 5. The mounting base 1 is used to fix the device in a designated position. The cylinder 2 is mounted above the mounting base 1. The connecting block 2 is mounted on the movable end of the cylinder 2. The base 4 is mounted on the connecting block 3. The sleeve 5 is mounted on the base 4. The base 4 has a vent hole 6, and the inlet end of the vent hole 6 is used to connect to an air pipe connector for ventilation. A hollow cavity is provided inside the sleeve 5, and a marking needle 10 is provided inside the hollow cavity. A marking port for the tip of the marking needle is provided at the end of the sleeve 5 away from the base 4. The outlet end of the vent hole 6 is connected to the hollow cavity. The cavity is connected to allow the engraving needle 10 to move along the length of the sleeve 5 by applying force to the head of the engraving needle through air. An exhaust hole 8 is provided in the hollow cavity portion of the sleeve 5, and the distance from the exhaust hole 8 to the end of the sleeve 5 away from the base 4 is less than the length of the engraving needle 10. A spring 9 is fitted on the engraving needle 10, with one end of the spring 9 connected to the head of the engraving needle 10 and the other end of the spring 9 fixed to the sleeve 5, forming an engraving structure that allows the engraving needle 10 to continuously extend out of and retract into the sleeve 5 when it moves along the length of the sleeve 5.

[0025] Preferably, it also includes a sealing ring 7 disposed on the inner wall of the hollow cavity of the sleeve 5 for contacting and engaging with the head end of the engraving needle 10, and the sealing ring 7 is close to the side of the base 4. After the engraving needle 10 retracts back into the sleeve 5 under the reset action of the spring 9, the head end of the engraving needle can contact the sealing ring 7 to prevent air from entering the hollow cavity of the sleeve 5 through the vent hole 6.

[0026] Preferably, the sleeve 5 is threaded onto the base 4. The sleeve 5 is an aluminum sleeve. The engraving needle 10 is a double tungsten carbide alloy needle. The head end of the vent hole 6 is configured as an RC1 / 8 threaded hole.

[0027] In this invention, the position of the sleeve 5 can be adjusted by the tightening length of the thread. The vent 8 is used to discharge compressed air when the engraving needle 10 is pressed to the position of the vent 8. Then, when the engraving needle 10 loses pressure, the restoring force of the spring 9 retracts the engraving needle 10 to the top of the sleeve 5. The engraving needle 10 is used for engraving automotive parts on an automotive production line.

[0028] In practical use, the cylinder 2 first transports the base 4, sleeve 5, and engraving needle 10 to the engraving position. Then, compressed air is introduced through the vent 6 on the base 4. The compressed air enters the sleeve 5 through the base 4, pushing the engraving needle 10 forward. At this time, the spring 9 is compressed. When the engraving needle 10 reaches the vicinity of the exhaust hole 8 on the sleeve 5 (but not quite there), the engraving needle 10 extends out of the engraving opening of the sleeve 5. The vent 6 on the base 4 stops supplying compressed air, and the compressed air in the sleeve 5 is discharged through the exhaust hole 8. At this time, under the reset action of the compressed spring 9, the engraving needle 10 retracts to the position of the sealing ring 7. By introducing and stopping the supply of compressed air through the vent 6 on the base 4, the continuous extension and retraction of the engraving needle 10 can be achieved to realize high-frequency engraving.
