[0002] According to the research and development personnel of the applicant, some of the metal products with complex shapes are currently processed by lost foam casting (such as stainless steel or titanium alloy golf head casting), and the paraffin wax embryos used in the casting process are still mainly manually assembled (assembled). This not only has high labor intensity, but also has low assembly precision and low yield rate. Therefore, new equipment and technology are urgently needed to improve its production efficiency. Because the wax embryos rely on manual assembly, the finished products have certain deformation and dimensional deviations, which makes the position of the cast finished products deviate, and it is difficult to promote automation in subsequent processes. In addition, considering the wide variety of products, the equipment must also take into account versatility and scalability. Existing technology and equipment are not yet up to the task, so it is particularly important to develop automated wax embryo assembly equipment.

[0013] A manufacturing method of a wax model assembly production line system, comprising the above-mentioned wax model assembly production line system, and the manufacturing method comprises the following steps:

[0014] a. The first robot completes the wax mold assembly on the positioning turntable, and the positioning turntable moves to the annular logistics line through the slide rail. The wax mold assembly is manually taken out from the positioning turntable and inspected. If the wax mold assembly meets the manual inspection requirements, it is placed on the annular logistics line. According to customer requirements, a manual inspection link is designed in the process of taking and placing the annular logistics line. This inspection link cannot be completed by the equipment, so it is designed to be manually taken. After manual inspection and confirmation, it is placed on the annular logistics line; in the process of completing the wax mold assembly, the first robot places the first wax embryo of the feeding turntable on the second wax embryo of the positioning turntable through the first fixture to complete the wax mold assembly. The first robot then bakes and reinforces the wax mold assembly through a flame spray gun.

[0015] b. Alcohol and interface agent are placed in the two cavities on the cleaning box respectively. The second robot clamps the wax mold assembly from the circular logistics line and places it in the alcohol cleaning chamber. Then the second robot drives the wax mold assembly to be placed on the rotating disk to complete the alcohol cleaning and drying work. Finally, the second robot places the wax mold assembly on the first station of the static rack. The wax mold assembly needs to be left on the static rack for 8 to 10 minutes. The second robot then clamps the wax mold assembly to the circular logistics line to continue to take materials to complete the alcohol cleaning and drying work, and then places it on the second station of the static rack. Then the second robot clamps the wax mold assembly on the first station of the static rack to continue the next process.

[0016] c. The next process is: after the second robot picks up the wax model assembly from the first station of the static rack, the second robot drives the wax model assembly to be placed in the interface agent soaking chamber, and then the second robot drives the wax model assembly to be placed on the rotating disk to complete the soaking interface agent drying work, and then the second robot puts the wax model assembly back to the circular logistics line;

[0017] d. When the wax mold assembly of step c is moved from one end of the annular logistics line to the other end, the wax mold assembly of step c also completes the static process, and the wax mold assembly is manually taken out at the other end of the annular logistics line for manual slurry brushing. Slurry brushing is to manually pre-apply mud at some corners of the first wax embryo to ensure that there will be no bubbles between the slurry and the first wax embryo when the wax mold assembly is dipped in slurry in the subsequent process;

[0018] Manual slurry brushing is a delicate job that requires inspection while applying. If it is not applied properly, it will seriously affect the quality of the cast product. The customer is concerned about the quality of the robot slurry brushing and requires manual work to be retained here.

[0019] e. After the wax model assembly of step d is completed, the wax model assembly is manually placed on the rotating frame, and the third robot clamps the wax model assembly on the rotating frame through the third clamp to sequentially perform the slurry dipping, slurry return, and sanding processes;

[0020] f. After the wax model assembly in step e is completed, the third robot places the wax model assembly on the unloading vehicle.

[0021] The beneficial effects of the present invention are as follows:

[0022] This equipment can achieve a product position error of less than 0.1mm after wax model assembly. This equipment can be compatible with multiple models of products by adjusting the fixture. The production line can automatically complete the wax model assembly process and produce qualified products.

[0023] The production line of this equipment retains some manual processes, combines manual and intelligent processes, effectively reduces manual labor intensity, and produces qualified products. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] b. Alcohol and interface agent are placed in the two cavities on the cleaning box 25 respectively.

Then the second robot 19 drives the wax mold assembly to be placed on the rotating disk 22 to complete the alcohol cleaning and drying work. Finally, the second robot 19 places the wax mold assembly on the first station of the static rack 32. The wax mold assembly needs to be left to stand on the static rack 32 for 8 to 10 minutes. The second robot 19 clamps the wax mold assembly from the annular logistics line 17 to continue to take materials to complete the alcohol cleaning and drying work, and then places it on the second station of the static rack 32. Then the second robot 19 clamps the wax mold assembly on the first station of the static rack 32 to continue the next process.

[0072] c.
