Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0050] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0051] Example 1

[0052] like Figure 1 As shown, an automatic assembly machine for battery pack water connectors includes a body 1, mounted with a conveyor device. In this embodiment, a ring-shaped conveyor disc 2 is used. A first drive motor 21 is mounted below the ring-shaped conveyor disc 2 to drive the ring-shaped conveyor disc 2 to rotate. A workpiece holder 22 is provided on the ring-shaped conveyor disc 2 for placing the base. Along the rotation direction of the ring-shaped turntable, a base loading station, an inspection station, a connector loading station, a pressing station, and a unloading station are sequentially arranged.

[0053] like Figure 1-2 Shown, the base loading station can be manually placed on the workpiece holder 22 and the spring is placed in the spring mounting hole of the base. The base with the spring can also be transported to the base loading station by other equipment.

[0054] like Figure 2 As shown, the inspection station is equipped with a photoelectric sensor 31 and a workpiece code scanner 32. The photoelectric sensor 31 detects whether a spring is installed on the base, and the workpiece code scanner 32 scans the code on the base. If a spring is detected, the annular conveyor 2 transports the base to the joint loading station. If no spring is detected, the annular conveyor 2 transports the base to the unloading device, which removes the base to the scrap storage.

[0055] like Figure 3 As shown, the joint loading station is provided with a material dividing device 41 , an oil brushing device 42 and a moving device 43 .

[0056] like Figure 4As shown, the material dividing device 41 is installed on the machine body 1, and the material dividing device 41 is connected to the external joint feeding mechanism, and the joint feeding mechanism continuously provides joints with consistent orientation for the battery joint automatic assembly machine. The material dividing device includes a material dividing mounting frame 411, on which a material dividing slide assembly 412 and a first pneumatic push rod 413 are installed, and a joint seat 414 is installed on the material dividing slide assembly 412, and two joint placement positions are provided on the joint seat, and the telescopic part of the first pneumatic push rod 413 is connected to the joint seat 414. When the external joint feeding mechanism transports the joint to one of the joint placement positions, the first pneumatic push rod 413 pushes the joint seat 414 to move, and when the external joint feeding mechanism transports the joint to the other joint placement position, joint detectors 415 are installed on the material dividing mounting frame 411 at the first position and the second position respectively.

[0057] like Figure 5 As shown, the oil brushing device 42 is installed on the machine body 1 between the material distribution device 41 and the annular conveyor plate 2. The oil brushing device 42 includes an oil brushing mounting frame 421, on which an oil brushing sponge 422 is provided. The oil brushing mounting frame is provided with an oil inlet channel and an oil overflow channel. The oil inlet channel is connected to the oil brushing sponge and is connected to the oil tank through the oil feed pump. The oil overflow channel is used to discharge overflowed oil.

[0058] like Figure 6-7 As shown, the moving device 43 is installed on the machine body 1. The moving device 43 includes a mounting frame 431, and the mounting frame 431 is located above the oil brushing device 42. A first slide rail assembly 432 is installed on the mounting frame 431, and the first slide rail assembly 432 is erected between the material distributing device 41 and the annular conveyor plate 2 and is located above the oil brushing device 42. A second slide rail assembly 433 is installed on the first slide rail assembly 432, and the second slide rail assembly 433 is perpendicular to the first slide rail assembly 432, and the second slide rail assembly 433 is connected to the first slide rail assembly 432 through a slider. A second drive motor 434 is installed on the mounting frame 431, and the second drive motor 434 is used to drive the second slide rail assembly 433 to move on the first slide rail assembly 432. Two third slide rail assemblies 435 are installed on the second slide rail assembly 433. Each third rail assembly 435 is associated with a second pneumatic push rod 436, which is used to propel the third rail assembly 435 along the second rail assembly 433. The third rail assembly 435 is perpendicular to the plane of the first rail assembly 432 and the second rail assembly 433. Each third rail assembly 435 is equipped with a joint clamp 437 and a third pneumatic push rod 438, which is used to drive the joint clamp 437 along the third rail assembly 435. A rotating device 439 is installed between one of the joint clamps 437 and the third rail assembly 435.

[0059] When a joint needs to be loaded, the second drive motor 434 drives the second slide rail assembly 433 to move along the first slide rail assembly 432 toward the material distributor 41, moving it above the distributor 41. The joint clamping jaw 437 on the movable mechanism 43, near the first position, then grabs the joint at the first position. After the joint detector 415 at the first position detects that the joint has been removed, the first pneumatic push rod 413 extends and pushes another joint to the second position. The other joint clamping jaw 437 then grabs the second joint and, using its rotating mechanism, rotates it 180°, so that both joints face outward.

[0060] Then the second drive motor 434 drives the second slide rail assembly 433 to move above the oil brushing device, and the third pneumatic push rod 438 pushes the joint clamp 437 downward to make the joint fully contact with the oil brushing sponge 422, and brush lubricating oil on the joint. After the oil brushing is completed, the third pneumatic push rod 438 pulls the joint clamp 437 downward to its original position. Then the second drive motor 434 drives the second slide rail assembly 433 to move above the workpiece seat 22. The second pneumatic push rod 436 pushes the third slide rail assembly 435 to move the joint so that the joint is aligned with the mounting hole of the base. The third pneumatic push rod 438 pushes the joint clamp 437 downward to place the joint in the mounting hole, and then the joint clamp releases the joint and the joint clamp 437 is reset.

[0061] After the connector is placed in the mounting hole, the annular conveyor plate 2 conveys the base plate and the connector to the pressing station.

[0062] like Figure 8-9 As shown, a manipulator and a pressing device are installed on the pressing station. The manipulator is not shown in the figure.

The clamp 52 includes a clamping bracket 521, and a lifting device is installed on the clamping bracket 521. The lifting device of this embodiment is an electric push rod 522 driven by a servo motor. A pressing plate 523 is installed on the lifting device, and a pressing head 524 is installed on the pressing plate 523. The shape of the contact point between the pressing head 524 and the joint can completely fit the joint, so that the joint is more evenly stressed when compressed. A guide rod 525 is installed on the clamping bracket 521. The guide rod 525 is connected to the pressing plate 523 and is used to ensure the stability of the movement direction of the pressing plate during the pressing process of the pressing plate. The conveying slide assembly 51 is used to transport the base plate and the joint to the bottom of the pressing head 524 and align the position. It can also move another joint to the bottom of the pressing head 524 after one joint is pressed. In this embodiment, the workbench 512 is driven by the third drive motor 511 to slide on the conveying slide assembly 51.

[0065] When the base and the joint are pressed tightly, the third drive motor 511 cooperates with the manipulator to move the pressed base and the joint to the annular conveyor plate 2 , and the annular conveyor plate 2 conveys them to the unloading station.

[0066] like Figure 10 As shown, a blanking device 6 is installed on the blanking station, and the blanking device includes a blanking mounting frame 61, and a first blanking slide assembly 62 and a fourth pneumatic push rod 63 are installed on the blanking mounting frame 61.

The assembly method of the battery pack water connector automatic assembly machine according to claim 7, characterized in that: Wherein step S3 comprises the following steps: S3.1 If the spring passes the inspection, the base is transported to the joint loading station by the conveyor; S3.2 The second drive motor drives the second slide rail assembly to move on the first slide rail assembly toward the material distribution device, and moves to above the material distribution device; S3.3 The joint gripper on the moving device, which is near the first position, grips the joint at the first position. After the joint detector at the first position detects that the joint has been gripped, the first pneumatic push rod extends to push the other joint to the second position. The other joint gripper then grips the second joint and rotates the joint 180° using the rotation device on the gripper. S3.4 The second drive motor drives the second slide rail assembly to move above the oil brushing device. The third pneumatic push rod pushes the joint clamp downward to ensure full contact between the joint and the oil brushing sponge, and then applies lubricating oil to the joint. S3.5 After the oiling is completed, the third pneumatic push rod pulls the joint jaws down to their original position; S3.6 The second drive motor drives the second slide rail assembly to move above the workpiece base, and then the second pneumatic push rod pushes the third slide rail assembly to move the joint so that the joint is aligned with the mounting hole of the base. The third pneumatic push rod then pushes the joint clamp downward to place the joint in the mounting hole. The joint clamp then releases the joint and resets.
