Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an automatic mold changing mechanism with detection and replacement functions. Background Technology

[0002] A riveting die is a tool used for electromagnetic riveting, allowing the rivet to be upset in a single pass within the die cavity. The die presses the rivet into two or more layers of sheet metal using pressure and speed. Under the pressure of the rivet, the sheet metal undergoes plastic deformation, and the rivet legs gradually open, forming a stable mechanical interlocking structure. This process includes four stages: clamping, punching, expansion, and riveting completion. A riveting mold, on the other hand, uses external force to join parts together to form a single unit. Its main difference from other molds lies in its specific application scenarios and process requirements.

[0003] A search revealed a patent with publication number CN220739384U entitled "A Die Changing Device for a Riveting Machine." The technical problem it addresses is that a single riveting machine can only install one set of automatic feeding tools and upper dies, and can only rivet one type of rivet. When a single riveting machine rivets two or more types of rivets, a different tool needs to be changed. This requires removing the current tool and manually changing the automatic feeding tool and upper and lower dies, resulting in significant waiting time for die changes. Consequently, product waiting time during riveting is long, and processing efficiency is slow. The solution involves controlling the left-right movement of the lateral moving module and the up-down movement of the machine head's driving module, along with the pneumatic opening and clamping of the riveting machine head, to achieve automatic die changing for multiple rivets of different specifications. This allows one machine to rivet multiple types of rivets without tool changes, while maintaining the machine's economic efficiency and minimizing additional costs. It also reduces downtime for product riveting while waiting for die changes, improving processing efficiency. However, the following drawbacks still need to be addressed: damaged rivets cannot be identified or automatically replaced. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic mold changing mechanism with detection and replacement functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic mold changing mechanism with detection and replacement functions includes a stand, a riveting machine body slidably disposed on the outside of the stand, and a riveting mold mounting cavity fixedly disposed at the top of the riveting machine body. A riveting mold changing robot is disposed on the outside of the stand, and a riveting mold picking manipulator and a riveting mold waiting to be assembled manipulator are respectively disposed at the upper and lower ends of the riveting mold changing robot. A riveting mold color recognition sensor is fixedly disposed at the upper end of one end of the riveting machine body. A cross arm is fixedly installed at the top of the stand, and the cross arm is arranged parallel to the riveting machine body. A fixed frame is slidably disposed at one end of the cross arm, and a riveting mold detection camera is rotatably disposed inside the fixed frame.

[0007] Preferably, the support legs are fixedly installed on three sides of the bottom end of the support frame.

[0008] Preferably, the riveting machine body contains an intelligent controller.

[0009] Preferably, the riveting die mounting cavity of the riveting machine is provided with multiple sets of riveting dies, and the outer wall color of each set of riveting dies is different, and the outer wall color of each set of riveting dies is the same as the color of its corresponding die base.

[0010] Preferably, the camera end of the riveting die detection camera is located at one end of the riveting machine body and the opening end of the riveting die mounting cavity of the riveting machine.

[0011] Preferably, both the upright frame and the cross arm are equipped with a moving transmission mechanism, and the two moving transmission mechanisms are respectively fixedly connected to the outer wall of the riveting machine body and the outer wall of the fixed frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model proposes an automatic mold changing mechanism with detection and replacement functions. After receiving the mold that needs to be replaced, the mold changing robot goes to the mold changing mechanism to replace the mold. After the mold taking robot takes the mold, it goes to the mold color recognition sensor to detect whether the color of the mold corresponds to the set color of the point taken by the mold. After confirmation, the mold assembly robot takes the taken mold to the mold detection camera to check whether the taken mold meets the preset value. After the detection is correct, it goes to the riveting. The camera end of the mold detection camera is located at one end of the riveting machine body and the opening end of the riveting mold mounting cavity of the riveting machine, which can help to understand whether the color of the mold is consistent after the mold change.

[0014] 2. The automatic mold changing mechanism with detection and replacement functions proposed in this utility model has different colors for the outer walls of multiple sets of rivet dies. The outer wall color of each set of rivet dies is the same as the color of its corresponding mold base. This allows the rivet dies used in the GRIPP mold changing system to have different colors, and the mold base color corresponding to each rivet die is the same. This allows workers to intuitively see whether the rivet die is in the correct mold placement position, avoiding incorrect use of rivet dies. In addition, a rivet die color recognition sensor is fixedly installed at the upper end of one end of the riveting machine body, and a rivet die detection camera is installed at one end of the cross arm. After each mold removal by the rivet die changing robot, the rivet die color recognition sensor will detect whether the rivet die color corresponds to the mold base, avoiding incorrect mold removal.

[0020] Reference Figure 1-4 An automatic mold changing mechanism with detection and replacement functions includes a stand 4, a riveting machine body 8 slidably arranged on the outside of the stand 4, and a riveting mold mounting cavity 9 fixedly arranged at the top of the riveting machine body 8. A riveting mold changing robot 1 is arranged on the outside of the stand 4, and a riveting mold picking robot 2 and a riveting mold waiting to be assembled robot 3 are respectively arranged at the upper and lower ends of the riveting mold changing robot 1. A riveting mold color recognition sensor 10 is fixedly arranged at the upper end of one end of the riveting machine body 8. A cross arm 6 is fixedly installed at the top of the stand 4, and the cross arm 6 is arranged parallel to the riveting machine body 8. A fixed frame is slidably installed at one end of the cross arm 6, and a riveting mold detection camera 7 is rotatably installed inside the fixed frame.

[0021] In this utility model, support feet 5 are fixedly installed on three sides of the bottom end of the upright frame 4, which effectively enhances the stability of the upright frame 4;

[0022] The riveting machine body 8 contains an intelligent controller;

[0023] The riveting die installation cavity 9 of the riveting press is equipped with multiple sets of riveting dies 11, and the outer wall color of each set of riveting dies 11 is different. The outer wall color of each set of riveting dies 11 is the same as the color of its corresponding die base. This makes the riveting dies 11 used in the GRIPP die changing system have different colors, and the die base corresponding to each riveting die 11 is the same color. This way, the workers can intuitively see whether the riveting die 11 is in the correct die placement position and avoid using the riveting die incorrectly.

[0024] The camera end of the riveting die inspection camera 7 is located at one end of the riveting press body 8 and the opening end of the riveting die mounting cavity 9 of the riveting press, which can help to understand whether the color of the riveting die 11 is consistent after the die change.

[0025] Both the upright frame 4 and the cross arm 6 are equipped with a moving transmission mechanism, and the two moving transmission mechanisms are fixedly connected to the outer wall of the riveting machine body 8 and the outer wall of the fixed frame, respectively.

[0026] Working principle: After receiving the riveting mold 11 to be replaced, the riveting mold replacement robot 1 goes to the mold changing mechanism to replace the riveting mold 11. The riveting mold picking robot 2 picks up the mold and goes to the riveting mold color recognition sensor 10 to check whether the color of the riveting mold 11 corresponds to the color setting of the point picked up by the riveting mold. After confirmation, the riveting mold assembly robot 3 takes the picked-up riveting mold 11 to the riveting mold detection camera 7 to check whether the picked-up riveting mold meets the preset value. After the detection is correct, it goes to riveting. The camera end of the riveting mold detection camera 7 is located at one end of the riveting press body 8 and the opening end of the riveting mold mounting cavity 9 of the riveting press, which can help to understand whether the color of the riveting mold 11 is consistent after the mold replacement.

[0027] Because the outer wall colors of multiple sets of riveting dies 11 are different, and the outer wall color of each set of riveting dies 11 is the same as the color of its corresponding mold base, the riveting dies 11 used in the GRIPP mold changing system have different colors, and the mold base corresponding to each riveting die 11 is the same color. This allows workers to see intuitively whether the riveting die 11 is in the correct mold placement position, avoiding incorrect use of the riveting die. In addition, a riveting die color recognition sensor 10 is fixedly installed at the upper end of one end of the riveting press body 8, and a riveting die detection camera 7 is installed at one end of the cross arm 6. After each mold removal, the riveting die changing robot 1 will be detected by the riveting die color recognition sensor 10 to check whether the color of the riveting die 11 corresponds to the mold base, thus avoiding the wrong riveting die 11 being removed.
