Detailed implementation manners

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Refer to Figures 1 - 5 , the present invention provides a battery pack water joint and pipe joint assembly device, which is used to automatically assemble the pipe joint into the valve body of the battery pack water joint and perform pre - pressing and fixing, providing a stable basis for the subsequent pressing process.

[0028] The battery pack water joint and pipe joint assembly device includes a discharging mechanism 61, a material distributing mechanism 63, a material transferring mechanism 64 and a pre - pressing mechanism 65.

[0029] The discharging mechanism 61 is used for discharging the pipe joint. It includes a vibrating disk and a conveying track. The pipe joint is sent to the conveying track one by one through the vibrating disk, ensuring that the pipe joints are arranged in an orderly manner and smoothly enter the material distributing mechanism 63; when discharging, the pipe joint is horizontal, and its length direction is parallel to the discharging direction of the discharging mechanism 61, that is, perpendicular to the sliding direction of the material distributing base 631. One end of the pipe body of the pipe joint facing away from the discharging mechanism 61, and the joint is upward.

[0030] The material distributing mechanism 63 is arranged at the discharging end of the discharging mechanism 61 and is used for distributing the pipe joint. The material distributing mechanism 63 includes a material distributing base 631, which can achieve horizontal sliding. Its sliding direction is perpendicular to the discharging direction of the discharging mechanism 61. The material distributing base 631 can move between a first position and a second position. Among them, the first position is used to dock with the discharging mechanism 61, and the material distributing base 631 at the second position is located on the movement path of the material transferring mechanism 64 and is used to dock with the material transferring mechanism 64 to ensure the accurate transfer of the pipe joint.

[0031] A material distribution groove 6310 is provided on the material distribution seat 631. The shape of the material distribution groove 6310 matches that of the pipe joint. One end of the material distribution groove 6310 facing the discharging mechanism 61 is open, and is used for the pipe joint at the discharging end of the discharging mechanism 61 to enter. A clamping jaw groove is provided at one end of the material distribution groove 6310 facing away (far from) the discharging mechanism 61, and is used for the clamping jaw on the material moving mechanism 64 to pass through and realize material clamping. The upper end of the material distribution groove 6310 is open, and is used for taking out the pipe joint upward from the material distribution groove 6310; when in the first position, the material distribution groove 6310 on the material distribution seat 631 can be butted against the discharging end of the discharging mechanism 61, and further enable the pipe joint at the discharging end of the discharging mechanism 61 to enter the material distribution groove 6310.

[0032] There are multiple material distribution grooves 6310, and the number of them is the same as that of the pipe joints on the water connector of the battery pack. And the multiple material distribution grooves 6310 are arranged in sequence along the sliding direction of the material distribution seat 631; in this embodiment, there are two pipe joints on the water connector of the battery pack, so there are also two material distribution grooves 6310.

[0033] In order to improve the material distribution accuracy and efficiency, in this application, the material distribution mechanism 63 further includes a horizontally sliding limit seat 6321 and a sliding seat 6331. The limit seat 6321 and the sliding seat 6331 are on the same sliding path. Specifically, they are on the same slide rail, and their sliding direction is perpendicular to the discharging direction of the discharging mechanism 61. The material distribution seat 631 is installed on the sliding seat 6331. In this embodiment, the material distribution seat 631 is fixed on the top of the sliding seat 6331. The limit seat 6321 can move between the third position and the fourth position, and the sliding seat 6331 can abut against the limit seat 6321 at the third position and the fourth position, so as to respectively butt the two material distribution grooves 6310 against the discharging end of the discharging mechanism 61 and realize the respective feeding of the two material distribution grooves 6310.

[0034] Since the air cylinder has two extreme positions, when it needs to pause at the middle position, the requirement for gas is extremely high. At the same time, gas has compressibility. Therefore, the air cylinder cannot achieve precise positioning and stopping at the middle position, and it can only be realized by a lead screw module. However, the cost of the lead screw module is high and the volume is large, resulting in a need for a large installation space, which will disrupt the reasonable layout of the entire assembly device.

[0035] Therefore, by setting the above-mentioned limit seat 6321, which serves as an abutting end for limiting the sliding seat 6331 (material distribution seat 631). Specifically, the limit seat 6321 has two extreme positions, namely the third position and the fourth position. The third position and the fourth position respectively correspond to the docking of two material distribution grooves 6310 with the discharge end of the discharge mechanism 61. For example, when the limit seat 6321 is in the third position, the first material distribution groove 6310 is docked with the discharge mechanism 61, and when in the fourth position, the second material distribution groove 6310 is docked, ensuring accurate feeding; one end of the sliding seat 6331 serves as an abutting end to contact the limit seat 6321, and its other extreme position is the second position, that is, for docking with the material transfer mechanism 64. At this time, the material distribution groove 6310 is in a waiting state and is located on the movement path of the material transfer mechanism 64. The material transfer mechanism 64 can pick up materials from the material distribution seat 631 and move them into the fixture at the pipe assembly station, and achieve it on the valve body of the battery pack water joint in the fixture.

[0036] The pipe assembly station is a station for assembling pipe joints on the bottom plate of the battery pack water joint, and this station is set on the conveying device.

[0037] The material distribution mechanism 63 further includes a first cylinder 632 and a second cylinder 633. Among them, the output end of the first cylinder 632 is connected to the limit seat 6321 and is used to drive the limit seat 6321 to slide horizontally. The output end of the second cylinder 633 is connected to the sliding seat 6331 and is used to drive the sliding seat 6331 to slide horizontally. In this application, the second cylinder 633 is fixed on the limit seat 6321, which can greatly reduce the stroke of the second cylinder 633, thereby reducing the overall length and volume of the second cylinder 633 and improving the structural compactness.

[0038] At the same time, limit blocks 634 are provided at the extreme positions of the limit seat 6321 and the sliding seat 6331 for limiting and preventing over-travel. Specifically, there are two limit blocks 634. One is set at the third position of the limit seat 6321 for limiting the third position of the limit seat 6321, and one is set at the second position for limiting the second position of the sliding seat 6331.

[0039] The material transfer mechanism 64 is used to grab and move the pipe joint. Specifically, it can move the pipe joint on the material distribution seat 631 at the second position to the valve body of the battery pack water joint in the fixture at the pipe assembly station. During the movement, the pipe joint is flipped 180 degrees so that the joint of the pipe joint changes from facing upward to facing downward and is aligned with the docking end of the valve body.

[0040] In order to improve the assembly efficiency, in this application, the material transfer mechanism 64 can simultaneously grab multiple pipe joints in multiple material distribution grooves 6310 and achieve synchronous material transfer and assembly;

[0041] In this embodiment, the material transfer mechanism 64 includes a horizontal sliding seat 642 capable of realizing horizontal sliding and a lifting sliding seat 643 vertically and slidably arranged on the horizontal sliding seat 642. The sliding direction of the horizontal sliding seat 642 is perpendicular to the sliding direction of the material distribution seat 631. A rotary cylinder 644 corresponding to the material distribution groove 6310 is arranged on the lifting sliding seat 643. In this embodiment, there are two rotary cylinders 644. The rotation axis of the rotary cylinder 644 is parallel to the length direction of the material distribution groove 6310, that is, perpendicular to the moving direction of the material distribution seat 631. A clamping cylinder 645 is arranged at the output end of the rotary cylinder 644. The clamping cylinder 645 is a finger cylinder, which is horizontally arranged and the output end faces the material distribution seat 631. A clamping jaw is arranged at the output end of the clamping cylinder 645 for clamping the pipe fitting joint. Specifically, the clamping jaw includes an inner clamping jaw 6451 and an outer clamping jaw 6452 arranged in parallel. Both the inner clamping jaw 6451 and the outer clamping jaw 6452 are horizontally arranged and perpendicular to the sliding direction of the material distribution seat 631. The inner clamping jaw 6451 can be horizontally inserted into the pipe fitting joint. Specifically, it can be inserted into the pipe body of the pipe fitting joint. A clamping area is formed between the inner clamping jaw 6451 and the outer clamping jaw 6452 for clamping the pipe fitting joint. Specifically, it is used to clamp the pipe body of the pipe fitting joint. When grasping the material, the inner clamping jaw 6451 is inserted into the pipe body, and the outer clamping jaw 6452 is located outside the pipe body. Through the closing action of the clamping jaw, the pipe fitting joint is firmly clamped to ensure stable and non-shaking during the material transfer process. And during the material transfer process, the rotary cylinder 644 rotates 180 degrees to turn the joint of the pipe fitting joint from upward to downward, aligning it with the docking end of the valve body to ensure the assembly accuracy. In this application, the sliding direction of the horizontal sliding seat 642 is perpendicular to the sliding direction of the material distribution seat 631.

[0042] In order to improve the grasping accuracy, in this application, the side wall of the inner clamping jaw 6451 is provided with an inner clamping surface that can fit the inner wall of the pipe fitting joint, and the side wall of the outer clamping jaw 6452 is provided with an outer clamping surface that fits the outer wall of the pipe fitting joint. This can increase the contact area, thereby improving the stability and accuracy of grasping the material, and providing support for the precise assembly of the pipe fitting joint.

[0043] The preloading mechanism 65 is located directly above the fixture at the pipe fitting assembly station and is used to preload the pipe fitting joint onto the valve body to stably connect the pipe fitting joint to the valve body. The preloading mechanism 65 includes a vertically arranged preloading cylinder 651 and a pressing block 652 arranged at the output end of the preloading cylinder 651. A positioning groove corresponding to the pipe fitting joint is arranged on the bottom surface of the pressing block 652, which can allow part of the pipe fitting joint to be inserted, thereby improving the preloading stability of the pipe fitting joint and preventing the pipe fitting joint from shifting or tilting during preloading, ensuring the accuracy of the assembly process.

[0044] The pipe joint assembly device for the water joint of the battery pack of the utility model can realize the automatic grasping, moving, rotating and pre-pressing of the pipe joint, achieve precise assembly, improve production efficiency and assembly quality, be applicable to large-scale production lines, and reduce labor costs; a material separation mechanism is set up, which can realize automatic material separation, greatly improve the discharging efficiency, and avoid the interference between the material moving mechanism and the discharging mechanism, improve the overall structural compactness and reasonable layout; the multi-material separation slots are set up, which can realize the synchronous discharging of multiple pipes, cooperate with the material moving mechanism to grasp synchronously, and can realize the synchronous assembly of multiple pipes, greatly improve the assembly efficiency, shorten the production cycle, effectively control the assembly consistency of the pipes on the water joint of the battery pack, and have good product quality stability; a sliding limit seat is set up, which can provide abutment and multi-stage limit for the sliding seat, and greatly reduce the manufacturing cost on the premise of ensuring the moving accuracy of the sliding seat; the cylinder of the sliding seat is arranged on the limit seat, which can greatly reduce the stroke of the second cylinder, and then reduce the overall length and volume of the second cylinder, reduce the installation space and improve the structural compactness; a pre-pressing mechanism is set up, which can pre-press the pipe joint, ensure its stable connection with the valve body, reduce the assembly error, facilitate the subsequent precise pressing, enable the subsequent pressing process to be carried out without the support of a manipulator, further optimize the assembly process, improve the automation level and reduce the production cost; an insertion type jaw structure is adopted, which has high clamping stability, provides guarantee for precise assembly, ensures the close fit with the pipe joint during the assembly process, and reduces the assembly defects caused by loosening; the pipe joint assembly device for the water joint of the battery pack of the utility model has a compact structure, can realize automatic discharging, grasping, moving, rotating and pre-pressing, has high assembly precision and efficiency, ensures the consistency of product quality, is applicable to high-efficiency production lines, and reduces labor costs.
