Description

Technical Field

[0001] The utility model relates to the technical field of casting process equipment, in particular to a device for marking the outside of a sand mold and a sand box used in a casting molding production line. Background Art

[0002] The cast number is unique and serves as the identity ID of the casting. It plays an important role in the collection and statistics of production information of products in the casting process, and in product quality tracking and tracing. At the same time, with the application and popularization of production information management software in the foundry industry, cast number information has become an indispensable information element in the production information management system.

[0003] The method of engraving casting numbers or QR codes on castings cannot identify product information from the first casting process, but the casting number is produced in the molding process. The currently commonly used method is to put the sand core into the sand mold, and obtain the casting number on the surface of the casting after pouring. In this way, the casting numbers need to be manually sorted and the information needs to be manually transcribed during molding. The casting numbers on the sand mold in the box are manually identified and recorded during the subsequent box assembling. The casting number information must be pasted on the outside of the box for collecting casting information during pouring. The process is cumbersome and prone to wrong numbers. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a marking device for a casting molding production line, which is used for online sand mold casting number engraving on the molding production line, and simultaneously generates a QR code logo consistent with the casting number information, which is used for subsequent process production information collection, thereby realizing sand mold casting number manufacturing and casting process production data collection.

[0005] The technical method adopted by the utility model to solve the technical problem is as follows: the marking device of the casting molding production line is composed of a sand mold casting number laser marking device inside the production line box and a QR code printing and labeling device outside the sand box, specifically including: a three-axis truss manipulator 1, a laser marking machine 2, a printing and labeling all-in-one machine 3, and a control cabinet 4. The three-axis truss manipulator 1 is composed of an X-axis travel module 11, a Y-axis travel module 12, and a Z-axis travel module 13; the laser marking machine 2 includes a laser control box 21, a laser marking head 22, a laser rangefinder 23, and a dust suction pipe 24.

[0006] The laser marking machine 2 is fixed on the Z-axis travel module 13 of the three-axis truss manipulator 1. The laser rangefinder 23 is placed next to the laser marking head 22. It is used to accurately measure the surface height of the sand mold and correct the height error caused by the wear of the sand box during actual production (that is, the deviation between the actual height of the sand mold and the initial digital model entered into the molding line information system caused by factors such as sand box wear). The suction port of the dust suction duct 24 is facing the position of the casting number 9 on the sand mold 8, which is consistent with the marking action of the laser marking head 22. It is used to absorb the smoke and dust generated during marking and the sand particles dispersed after high-temperature ablation.

[0007] The printer-labeler 3 is located to the side of the production line's roller conveyor 6, within the marking range of the smallest sand box used on the production line, facing the QR code label 5. The printer-labeler 3 generates a QR code that matches the cast number 9 engraved by the laser marker 2, prints a paper label, and affixes it to the outside of the sand box.

[0008] After the molding operation is completed, the sand box is taken off the line and enters the box closing process. During the box closing operation, the operator uses a handheld scanner to scan the QR code outside the sand box to complete the collection and upload of the completion information of the box closing process; the sand box after closing enters the pouring process. The operator uses a handheld scanner to scan the QR code outside the sand box to complete the collection and upload of the completion information of the pouring process.

[0009] The beneficial effects of the utility model are as follows: compared with the existing technology of marking on castings or making casting numbers on sand molds, the casting number font size of the sand mold laser marking is highly flexible, adaptable to the production of multiple varieties of products, with high marking efficiency. The cast casting number is clear and smooth. Combined with the QR code box scanning and recognition, it realizes the effective and fast collection of casting production information from molding to box assembly, pouring and other processes, reduces manual operations, and provides technical support for the digitalization and informationization upgrade of the casting production process.

[0018] like Figure 1 As shown, the marking device of the casting molding production line of the present invention includes: a three-axis truss manipulator 1, a laser marking machine 2, a printing and labeling integrated machine 3, and a control cabinet 4. The three-axis truss manipulator 1 is composed of an X-axis travel module 11, a Y-axis travel module 12, and a Z-axis travel module 13. The laser marking machine 2 includes a laser control box 21, a laser marking head 22, a laser rangefinder 23, and a dust suction pipe 24. It is fixed on the Z-axis travel module 13 of the three-axis truss manipulator 1. The dust suction port of the dust suction pipe 24 faces the position of the casting number 9 on the sand mold 8. The printing and labeling integrated machine 3 is arranged on the side of the forward direction of the production line roller 6, located within the marking range of the minimum specification sand box sand mold used on the production line, and facing the QR code label 5.

[0019] The sand mold marking device of the present invention is arranged before the last working station (i.e. the sand mold off-line station) of the molding line.

[0020] After the molding line completes the molding, hardening, demolding, coating, and drying of a box of sand, the box 7 moves to the preceding station of the marking equipment. The product model information from the production information management system is transmitted to the control cabinet 4. The laser marker 2 requests loading, and the sand box 7 moves forward to the marking station, stopping once in position. The three-axis truss robot 1 determines the X, Y, and Z axis travels based on the sand model information from the production information management system, moving the laser marker 2 into position. The laser rangefinder 23 accurately measures the sand mold surface height, correcting for height errors caused by actual production wear and tear, ensuring the engraving depth. The laser marking head 22 precisely moves into position, and the control cabinet 4 automatically sorts and generates the casting number 9, which can also be manually entered. The laser control box 21 initiates the marking process, and the dust collection duct 24 simultaneously activates to remove the smoke generated during marking and the sand particles dispersed after high-temperature ablation. The printer-labeler 3 simultaneously generates the QR code information and prints a paper label, which is affixed to the outside of the sand box 7. After the action is completed, the laser marking head 22 returns to its original position, sends a completion signal to the production line, uploads the marking information at the same time, and the sand box 7 is released.

[0021] The flask 7 is unloaded and a manually operated overhead crane is used to lift the flask to the assembly and pouring area. The assembly and pouring processes are carried out in the same area and there is no fixed order.

[0022] After each sand mold box is assembled, a person uses a handheld scanner to scan the QR code on the outside of the sand box, and the assembly completion information is uploaded to the production information management system.

[0023] After each casting operation is completed, a person uses a handheld scanner to scan the QR code on the outside of the sand box, and the casting completion information is uploaded to the production information management system.

[0024] The sand is shaken out of the box and the castings with casting numbers are transferred.
