[0002] An electric vehicle refers to a vehicle powered by an on-vehicle power source and driven by an electric motor, meeting the requirements of road traffic and safety regulations. The types of electric vehicles can be divided into pure electric vehicles, hybrid electric vehicles, and fuel cell vehicles. A battery cooler is a key component for regulating the temperature of a battery pack in a liquid-cooled electric vehicle. Enhancing its heat exchange effect can reduce the required compressor speed or refrigerant displacement, thereby reducing power consumption and improving the cruising range and driving performance.

[0003] In the existing battery cooling structure, due to the structural influence, its base and joint are connected by interference fit. During the driving process of the vehicle, vibrations will occur, and continuous vibrations may cause the pipe joint to become loose, resulting in leakage and affecting normal cooling.

[0004] During the assembly process of the battery pack water joint, a spring needs to be placed between the joint and the base. In actual production, the spring is easily omitted, resulting in a low yield rate. And it is also difficult to visually detect defective products after the spring is omitted, and professional detection is required to find defective products. This increases the detection difficulty and cost.

Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0020] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0021] Embodiment 1 As Figure 1As shown in the figure, an automatic assembling machine for water connectors of a battery pack includes a machine body 1, on which a conveying device is installed. In this embodiment, an annular conveying disk 2 is adopted. A first driving motor 21 is installed below the annular conveying disk 2, and the first driving motor 21 is used to drive the annular conveying disk 2 to rotate. A workpiece seat 22 for placing the connection base is arranged on the annular conveying disk 2. Along the rotation direction of the annular turntable, a base loading station, an inspection station, a connector loading station, a pressing station and a unloading station are arranged in sequence.

[0022] As Figure 1-2 shown, at the base loading station, the base can be placed on the workpiece seat 22 manually and then the spring can be placed in the spring installation hole of the base. Or the base with a spring placed thereon can be conveyed to the base loading station by other equipment.

[0023] As Figure 2 shown, a photoelectric sensor 31 and a workpiece code scanner 32 are arranged at the inspection station. The photoelectric sensor 31 is used to detect whether a spring is installed on the base, and the workpiece code scanner 32 is used to scan the code on the base. When it is detected that a spring is installed, the annular conveying disk 2 sends the base to the connector loading station. When it is detected that no spring is installed, the annular conveying disk 2 sends the base to the unloading device, and the base is removed to the waste bin by the unloading device.

[0024] As Figure 3 shown, a material distribution device 41, an oil brushing device 42 and a moving device 43 are arranged at the connector loading station.

[0025] As Figure 4 shown, the material distribution device 41 is installed on the machine body 1. The material distribution device 41 is connected to an external connector loading mechanism, and the connector loading mechanism continuously provides connectors with the same orientation for the automatic assembling machine of battery connectors. The material distribution device includes a material distribution mounting frame 411, on which a material distribution slide rail assembly 412 and a first pneumatic push rod 413 are installed. A connector seat 414 is installed on the material distribution slide rail assembly 412. Two connector placement positions are arranged on the connector seat. The telescopic part of the first pneumatic push rod 413 is connected to the connector seat 414. After the external connector loading mechanism conveys a connector to one of the connector placement positions, the first pneumatic push rod 413 pushes the connector seat 414 to move. After the external connector loading mechanism conveys a connector to the other connector placement position, connector detectors 415 are respectively installed at the first position and the second position on the material distribution mounting frame 411.

[0026] As Figure 5As shown, the oiling device 42 is installed on the machine body 1 between the material distributing device 41 and the annular conveying disc 2. The oiling device 42 includes an oiling mounting frame 421, on which an oiling sponge 422 is provided. An oil inlet channel and an oil overflow channel are provided on the oiling mounting frame. The oil inlet channel is communicated with the oiling sponge and is communicated with the oil tank through an oil inlet pump. The oil overflow channel is used for discharging the overflowed oil.

[0027] As Figure 6-7 shown, the moving device 43 is installed on the machine body 1. The moving device 43 includes a mounting frame 431 which is located above the oiling device 42. A first slide rail assembly 432 is installed on the mounting frame 431. The first slide rail assembly 432 is arranged between the material distributing device 41 and the annular conveying disc 2 and is located above the oiling device 42. A second slide rail assembly 433 is installed on the first slide rail assembly 432. The second slide rail assembly 433 is perpendicular to the first slide rail assembly 432 and is connected to the first slide rail assembly 432 through a slider. A second driving motor 434 is installed on the mounting frame 431. The second driving 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 slide rail assembly 435 is respectively connected to a second pneumatic push rod 436. The second pneumatic push rod 436 is used to push the third slide rail assembly 435 to move on the second slide rail assembly 433. The third slide rail assembly 435 is perpendicular to the plane where the first slide rail assembly 432 and the second slide rail assembly 433 are located. A joint clamp 437 and a third pneumatic push rod 438 are installed on each third slide rail assembly 435. The third pneumatic push rod 438 is used to drive the joint clamp 437 to move on the third slide rail assembly 435. A rotating device 439 is installed between one of the joint clamps 437 and the third slide rail assembly 435.

[0028] When joint feeding is required, the second driving motor 434 drives the second slide rail assembly 433 to move on the first slide rail assembly 432 towards the material distributing device 41 until it is above the material distributing device 41. At this time, the joint clamp 437 at the first position on the moving device 43 clamps the joint at the first position. After the joint detector 415 at the first position detects that the joint has been clamped away, the first pneumatic push rod 413 extends to push another joint to the second position. At this time, another joint clamp 437 clamps the second joint and rotates the joint 180° through the rotating device thereon so that both joints face outwards.

[0029] Then, the second drive motor 434 drives the second slide rail assembly 433 to move above the oiling device. The third pneumatic push rod 438 pushes the joint gripper 437 downward, enabling the joint to be in full contact with the oiling sponge 422 and lubricating the joint. After the oiling is completed, the third pneumatic push rod 438 pulls the joint gripper 437 upward to its original position. Then, the second drive motor 434 drives the second slide rail assembly 433 to move above the workpiece seat 22. Next, the second pneumatic push rod 436 pushes the third slide rail assembly 435 to move so that the joint is aligned with the mounting hole of the base. Then, the third pneumatic push rod 438 pushes the joint gripper 437 downward to place the joint into the mounting hole. After that, the joint gripper releases the joint, and the joint gripper 437 resets.

[0030] After the joint is placed into the mounting hole, the annular conveyor disk 2 conveys the base plate and the joint to the pressing station.

[0031] As Figure 8-9 shown, a manipulator and a pressing device are installed at the pressing station. The manipulator is not shown in the figure.

[0033] A base placing rack 513 is installed on the workbench 512. Positioning push rods 514 are respectively installed on both sides of the base placing rack. In this application, the positioning push rods 514 adopt pneumatic push rods. The positioning push rods are used to keep the position of the joint stable when the joint is pressed. The presser 52 includes a pressing bracket 521. A lifting device is installed on the pressing bracket 521. In this embodiment, the lifting device is an electric push rod 522 driven by a servo motor. A pressing plate 523 is installed on the lifting device. A pressing head 524 is installed on the pressing plate 523. The shape of the contact surface between the pressing head 524 and the joint can be completely fitted with the joint, making the joint more evenly stressed when being pressed. A guiding rod 525 is installed on the pressing bracket 521. The guiding rod 525 is connected to the pressing plate 523 and is used to ensure the stable movement direction of the pressing plate during the downward pressing process. The conveying slide rail assembly 51 is used to convey the base plate and the joint to below the pressing head 524 and align them, and can also move another joint to below the pressing head 524 after one joint is pressed. In this embodiment, the third drive motor 511 drives the workbench 512 to slide on the conveying slide rail assembly 51.

[0034] After the base and the joint are pressed, the third drive motor 511 and the manipulator cooperate to move the pressed base and joint to the annular conveyor disk 2, and the annular conveyor disk 2 conveys them to the discharging station.

[0035] As Figure 10 shown, a blanking device 6 is installed at the blanking station. The blanking device includes a blanking mounting frame 61. A first blanking slide rail assembly 62 and a fourth pneumatic push rod 63 are installed on the blanking mounting frame 61.

The assembly method of an automatic assembly machine for battery pack water connectors according to claim 9, characterized in that, Among them, step S3 includes the following steps: S3.1 If the spring is detected to be qualified, the conveying device transports the base to the connector loading station. S3.2 The second driving motor drives the second slide rail assembly to move towards the feeding device on the first slide rail assembly and move above the feeding device. S3.3 The connector gripper near the first position on the moving device grabs the connector at the first position. After the connector detector at the first position detects that the connector has been grabbed, the first pneumatic push rod extends to push another connector to the second position, and then the other connector gripper grabs the second connector and rotates the connector 180° through the rotating device thereon. S3.4 The second driving motor drives the second slide rail assembly to move above the oiling device, and the third pneumatic push rod pushes the connector gripper downward to make the connector fully contact the oiling sponge and apply lubricating oil to the connector. S3.5 After oiling is completed, the third pneumatic push rod pulls the connector gripper downward to the original position. S3.6 The second driving motor drives the second slide rail assembly to move above the workpiece seat 22, and then the second pneumatic push rod pushes the third slide rail assembly to move to align the connector with the mounting hole of the base. Then the third pneumatic push rod pushes the connector gripper downward to place the connector in the mounting hole. Then the connector gripper releases the connector and the connector gripper resets.
