Description

Technical Field

[0001] The utility model relates to the field of battery pack processing equipment, in particular to an automatic core-pulling riveting equipment for a new energy battery pack housing. Background Art

[0002] At present, in the domestic automotive industry, due to factors such as the processing and cost of new energy vehicle battery housing products, there is a large amount of manual riveting of battery pack housings using manual tooling fixtures. Since the processing of tooling and clamping parts is mainly carried out by workers holding pneumatic riveting guns for riveting; there is a current desktop workstation using a truss to carry a hand-held pneumatic riveting gun for pneumatic riveting. However, because manual riveting requires high skills for workers (maintaining perpendicularity and maintaining pre-pressure), and there is a high risk of defective products when manually holding a pneumatic riveting gun for manual riveting, and the quality consistency of part riveting is poor. At the same time, the industrial-grade truss plane pneumatic riveting workstation has limitations in riveting multi-faceted parts, the consistency of riveting effects is insufficient, and the riveting of large battery pack parts cannot meet production requirements in terms of energy consumption, resources, time, etc. Therefore, the existing manual assembly riveting has defects such as missed riveting and uneven riveting tension. Summary of the Utility Model

[0003] In view of the above problems, the purpose of the utility model is to provide an automatic core-pulling riveting equipment for a new energy battery pack housing with consistent part riveting and improved riveting efficiency.

[0004] To achieve the above purpose, an automatic core-pulling riveting equipment for a new energy battery pack housing provided by the utility model includes a moving slide, a tooling fixture arranged on the moving slide, a first robot and a second robot respectively arranged on both sides of the moving slide, a part-gripping device arranged at the end of the first robot, and a pneumatic riveting gun arranged at the end of the second robot.

[0005] In some embodiments, both the first robot and the second robot are six-axis robots.

[0006] The beneficial effect of the utility model is to have the effects of consistent part riveting and improved riveting efficiency. Since the automatic core-pulling riveting is used to replace the manual core-pulling riveting after improvement, the time of the core-pulling riveting process is reduced, and the core-pulling riveting nails are uniformly placed in the automatic core-pulling riveting equipment for riveting. The time of manual core-pulling riveting is reduced, and the consistency of the riveting state of the connecting parts after core-pulling riveting is ensured, thereby ensuring the riveting quality of the product. For example, an automatic equipment controlled by a PLC, consisting of 2 six-axis robots, 1 automatic riveting gun, 1 automatic rivet feeder, and several components, can realize automatic feeding of the robot, automatic clamping of the workpiece, and automatic riveting of the equipment to the parts. Thus, a device that ensures the core-pulling riveting quality of the parts is achieved. The effects of consistent part riveting and improved riveting efficiency are realized. Brief Description of the Drawings

[0008] The present utility model will be further described in detail below with reference to the drawings.

[0009] As Figure 1 shown, an automatic core-pulling riveting device for a new energy battery pack housing includes a moving slide table 1, a tooling fixture 2 provided on the moving slide table 1, a first robot 3 and a second robot 4 respectively provided on both sides of the moving slide table 1, a component gripper 5 provided at the end of the first robot 3, and a pneumatic rivet gun provided at the end of the second robot 4. In some embodiments, both the first robot 3 and the second robot 4 are six-axis robots.

[0010] Working Principle

[0011] 1) After the welding process of the previous process is completed;

[0012] 2) The second robot 4 with the rivet gun resets;

[0013] 3) After program determination, the moving platform moves part A to the riveting process station;

[0014] 4) The first robot 3 for loading parts places part B on the tooling fixture 2;

[0015] 5) The tooling fixture 2 clamps the parts, and two workpiece sensors output signals to the control cabinet;

[0016] 6) The second robot 4 with the rivet gun aligns with the part station and aligns with the first riveting position;

[0017] 7) Perform the riveting program to rivet the parts;

[0018] 8) After the pneumatic rivet gun is executed, a signal indicating that the rivet is broken is fed back;

[0019] 9) The rivet feeder performs the rivet feeding program for the rivet gun;

[0020] 10) The second robot 4 moves to the next riveting point;

[0021] 11) After all the riveting points have completed the riveting program operation, the second robot 4 realigns and returns to zero, and at the same time removes the broken rivet waste rod;

[0022] 12) The tooling fixture 2 is opened:

[0023] 13) The handling robot grabs and transports the riveted parts to the next process;

[0024] 14) The welding fixture clamps the part, and the robot gripper releases the part.

[0025] 15) The second robot 4 with a riveting gun resets the count and enters the next cycle.
