[0032] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model; however, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used 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 different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Example 1

[0035] like Figure 1As shown, an automatic assembly machine for battery pack water connectors includes a machine body 1, on which a transport device is installed. In this embodiment, an annular conveyor plate 2 is used. A first drive motor 21 is installed below the annular conveyor plate 2, which drives the annular conveyor plate 2 to rotate. A workpiece seat 22 for placing a base 101 is provided on the annular conveyor plate 2. Along the rotation direction of the annular turntable, a base loading station, an inspection station, a connector loading station, a clamping station, and a unloading station are arranged in sequence.

[0036] like Figure 1-2 As shown, at the base loading station, the base 101 can be placed on the workpiece seat 22 manually, and then the spring can be placed in the spring mounting hole of the base 101. Alternatively, other equipment can transport the base 101 with the spring placed to the base loading station.

[0037] like Figure 2 As shown, the inspection station is equipped with a vision detector 31 and a workpiece code scanner 32. The vision detector 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 a spring is detected, the annular conveyor 2 sends the base to the joint loading station. When no spring is detected, the annular conveyor 2 sends the base to the unloading device, which then removes the base to the scrap storage.

[0038] The joint feeding station is equipped with a material distribution device 41, an oiling device 42, and a moving device 43.

[0039] like Figure 3 As shown, a material dispensing device 41 is mounted on the machine body 1. The material dispensing device 41 is connected to an external plug feeding mechanism, which continuously provides plugs with consistent orientation to the automatic battery connector assembly machine. The material dispensing device includes a material dispensing mounting frame 411, on which a material dispensing slide rail assembly 412 and a first pneumatic push rod 413 are mounted. A connector seat 414 is mounted on the material dispensing slide rail assembly 412, and the connector seat has two plug placement positions. The telescopic part of the first pneumatic push rod 413 is connected to the connector seat 414. When the external plug feeding mechanism delivers the plug 102 to one of the plug placement positions, the first pneumatic push rod 413 pushes the connector seat 414 to move until the external plug feeding mechanism delivers the plug 102 to the other plug placement position. Plug detectors 415 are respectively mounted on the mounting frame 411 at the first and second positions.

[0040] like Figure 4As 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 connected to the oil tank through an oil pump. The oil overflow channel is used to discharge overflowing oil.

[0041] like Figure 5-6 As shown, the moving device 43 is mounted 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 mounted on the mounting frame 431, positioned between the material dispensing device 41 and the annular conveyor plate 2, and located above the oiling device 42. A second slide rail assembly 433 is mounted on the first slide rail assembly 432, perpendicular to it, and connected to it via a slider. A second drive motor 434 is mounted on the mounting frame 431, driving the second slide rail assembly 433 to move on the first slide rail assembly 432. Two third slide rail assemblies 435 are mounted on the second slide rail assembly 433. Each third slide rail assembly 435 is connected to a second pneumatic push rod 436, which pushes 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 containing the first slide rail assembly 432 and the second slide rail assembly 433. Each third slide rail assembly 435 is equipped with a connector gripper 437 and a third pneumatic push rod 438, which drives the connector gripper 437 to move on the third slide rail assembly 435. A rotating device 439 is installed between one of the connector grippers 437 and the third slide rail assembly 435.

[0042] When connector feeding is required, the second drive motor 434 drives the second slide rail assembly 433 to move along the first slide rail assembly 432 towards the dispensing device 41, until it moves above the dispensing device 41. At this time, the connector gripper 437 on the moving device 43, near the first position, clamps the connector at the first position. After the plug detector 415 at the first position detects that the plug has been clamped, the first pneumatic push rod 413 extends and pushes the other plug to the second position. At this time, the other connector gripper 437 clamps the second connector and rotates the connector 180° via the rotating device on it, so that both plugs face outwards.

[0043] 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 connector jaws 437 downwards, ensuring full contact between the plug and the oiling sponge 422, and applying lubricant to the plug. After oiling, the third pneumatic push rod 438 pulls the connector jaws 437 back to their original position. Next, the second drive motor 434 drives the second slide rail assembly 433 to move above the workpiece seat 22. Then, the second pneumatic push rod 436 pushes the third slide rail assembly 435 to move, aligning the plug with the mounting hole of the base 101. Finally, the third pneumatic push rod 438 pushes the connector jaws 437 downwards, placing the plug in the mounting hole. The connector jaws then release the connector, and the connector jaws 437 return to their original position.

[0044] After the plug is placed in the mounting hole, the annular conveyor 2 transports the base plate and the plug to the clamping station.

[0045] like Figure 7-8 As shown, a robotic arm and a clamping device are installed on the clamping station. The robotic arm is not shown in the figure. The robotic arm only needs to be able to move the base plate and plug on the annular conveyor plate 2 to the clamping device. The robotic arm can use the technical means in the prior art, which will not be described in detail in this application.

[0046] The clamping device includes a conveyor slide rail assembly 51 and a clamping device 52, with a worktable 512 mounted on the conveyor slide rail assembly 51. In this embodiment, the worktable 512 is driven to slide on the conveyor slide rail assembly 51 by a third drive motor 511.

[0047] A base placement frame 513 is mounted on the workbench 512. Positioning push rods 514 are mounted on both sides of the base placement frame; in this application, the positioning push rods 514 are pneumatic push rods. The positioning push rods are used to maintain the stability of the plug position when the plug is pressed. The clamping device 52 includes a clamping bracket 521, on which a lifting device is mounted. In this embodiment, the lifting device is an electric push rod 522 driven by a servo motor. A pressure plate 523 is mounted on the lifting device, and a clamping head 524 is mounted on the pressure plate 523. The shape of the contact point between the clamping head 524 and the plug can completely fit the plug 102, making the force on the plug 102 more even when it is clamped. A guide rod 525 is mounted on the clamping bracket 521, and the guide rod 525 is connected to the pressure plate 523 to ensure the stability of the pressure plate's movement direction during the pressing process. The conveyor slide rail assembly 51 is used to transport the base plate and plug to the area below the clamping head 524 and align them. It can also move another plug to the area below the clamping head 524 after one plug has been clamped. In this embodiment, the worktable 512 is driven by the third drive motor 511 to slide on the conveyor slide rail assembly 51.

[0048] After the base 101 and plug 102 are pressed together, the third drive motor 511 and the robot arm work together to move the pressed base 101 and plug 102 onto the annular conveyor plate 2, and the annular conveyor plate 2 transports them to the unloading station.

[0049] like Figure 9 As shown, a feeding device 6 is installed on the feeding station. The feeding device includes a feeding mounting frame 61, on which a first feeding slide rail assembly 62 and a fourth pneumatic push rod 63 are mounted. A second feeding slide rail assembly 64 is mounted on the first feeding slide rail assembly 62. The fourth pneumatic push rod 63 is connected to the second feeding slide rail assembly 64 to push the second feeding slide rail assembly 64 to move on the first feeding slide rail assembly 62. A third pneumatic push rod 63 is mounted on the second feeding slide rail assembly 64. The third feeding slide rail assembly 65 and the fifth pneumatic push rod 66 are connected to the third feeding slide rail assembly 65. The fifth pneumatic push rod 66 is used to drive the third feeding slide rail assembly 65 to move on the second feeding slide rail assembly 64. The third feeding slide rail assembly 65 is equipped with a feeding gripper 68 and a sixth pneumatic push rod 67. The sixth pneumatic push rod 67 is connected to the feeding gripper 68. The sixth pneumatic push rod 67 is used to drive the feeding gripper 68 to move on the third feeding slide rail assembly 65.

[0050] An assembly method for an automatic battery pack water connector assembly machine includes the following steps:

[0051] S1 Place the spring-loaded base onto the transport device at the base loading station;

[0052] The S2 transport device transports the base and spring to the inspection station, inspects whether the spring is qualified or whether there are any missing springs, and scans and records the base code.

[0053] S3 If the spring test is qualified, the transport device will transport the base to the joint loading station. The moving device will grab the joints assigned to the first and second positions by the material distribution device. After adjusting the direction of the joints, it will be moved to the oiling device to complete the oiling. Then the oiled joints will be moved and placed on the base.

[0054] S4 transports the base with the plug to the clamping station via a transport device, and then the clamping device on the clamping station clamps the plug to the base plate;

[0055] S5 transports the compacted base plate to the unloading station by the transport device, and the unloading device at the unloading station completes the unloading to obtain the battery pack water connector.

[0056] S6 If step S2 detects that the spring installation is not up to standard or that a spring is missing, the base plate will be transported to the unloading station by the transport device and unloaded into the scrap warehouse by the unloading device.

[0057] Step S3 includes the following steps:

[0058] S3.1 If the spring passes the inspection, the base shall be transported to the joint loading station by the transport device;

[0059] 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 it above the material distribution device;

[0060] S3.3 The connector jaws on the moving device near the first position clamp the connector at the first position. After the plug detector at the first position detects that the plug has been clamped, the first pneumatic push rod extends to push another plug to the second position. Then, another connector jaws clamp the second connector and rotate the connector 180° through the rotating device on it.

[0061] S3.4 The second drive motor drives the second slide rail assembly to move above the oil brushing device, and the third pneumatic push rod pushes the connector jaws downward so that the plug can fully contact the oil brushing sponge and apply lubricating oil to the plug;

[0062] After the S3.5 is painted, the third pneumatic push rod will pull the connector jaws down to their original position;

[0063] S3.6 The second drive 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 so that the plug is aligned with the mounting hole of the base. Then the third pneumatic push rod pushes the connector jaws downward to place the plug in the mounting hole. After that, the connector jaws release the connector and reset the connector jaws.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
