Technical Field

[0001] This invention relates to the field of U-shaped liquid cooling tube manufacturing technology, specifically to a U-shaped liquid cooling tube assembly equipment and method. Background Technology

[0002] The key component of an electric vehicle is the power battery. Because the battery generates heat during charging and discharging, it needs to be cooled. Current technology generally uses liquid cooling pipes to dissipate heat from the battery. However, existing technologies have limitations such as… Figure 1 The U-shaped liquid cooling tube shown includes a U-shaped flat tube, an L-shaped flat tube, a connecting manifold, an outlet manifold, and an inlet manifold. The bends of the U-shaped and L-shaped flat tubes are on the same side and connected via the connecting manifold. The end of the U-shaped flat tube furthest from the connecting manifold is connected to the outlet manifold, and the end of the L-shaped flat tube furthest from the connecting manifold is connected to the inlet manifold. The U-shaped liquid cooling tube is generally assembled using the following method: the manifolds on both sides of the product are fixed, and the flat tube moves up and down with the equipment to assemble with the manifolds.

[0003] However, the above assembly scheme has the following drawbacks: 1. Complex structure: The existing assembly equipment has a complex structure and high manufacturing cost, which is not conducive to its widespread application; 2. High defect rate: It has high requirements for the bending angle of the U-tube and the dimensional accuracy of the fit between the U-tube and each manifold, resulting in low industrialization capability; 3. Low assembly efficiency: Due to the complex structure of the existing assembly equipment, it is hydraulically started, has many operating actions, and the equipment runs slowly with a low production cycle. Summary of the Invention

[0004] This invention provides a low-cost, easy-to-assemble and operate U-shaped liquid cooling tube assembly device and method.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0033] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions: (Refer to...) Figure 1 , Figure 2 A U-shaped liquid cooling tube assembly device includes a traveling system assembly 10, an assembly equipment assembly 20, a vertical assembly system assembly 30, and a control system assembly 60. The assembly equipment assembly is mounted on the traveling system assembly and is used to fix the U-shaped liquid cooling tube. Two vertical assembly systems are provided, symmetrically distributed along the ends of the assembly equipment assembly. One side of each assembly equipment assembly has a track running assembly 40 for driving the lateral movement of that vertical assembly system assembly, and the other side of the assembly equipment assembly has a lateral assembly assembly 50 that moves relative to that vertical assembly system assembly. The control system assembly controls the vertical and lateral assembly assemblies to perform assembly actions. In use, the U-shaped flat tube 01, L-shaped flat tube 02, and connecting... The U-shaped liquid cooling pipe, consisting of manifold 03, outlet manifold 04, and inlet manifold 05, is placed on the assembly equipment assembly for fixing the components. The vertical assembly system assembly on one side of the assembly equipment assembly is positioned above the manifold on that side under the movement of the track running assembly. Then, under the action of the vertical assembly system assemblies on both sides, the manifold is assembled with the U-shaped flat pipe and the L-shaped flat pipe. Afterward, the horizontal assembly assembly is used to press the manifold together to achieve the assembly of the manifold with the L-shaped flat pipe. This completes the assembly of the U-shaped liquid cooling pipe. This invention uses the method of fixing the U-shaped flat pipe and the L-shaped flat pipe and driving the manifold closer to the flat pipe to achieve the assembly of the U-shaped liquid cooling pipe. The entire equipment has a simple structure, simple assembly process, low requirements for assembly accuracy, and has the advantages of high assembly efficiency and low defect rate.

[0035] Reference Figure 3As a preferred technical solution in this embodiment, the gantry system assembly 10 includes a gantry frame 110, a frame platform 120, and universal control wheels 130. The frame platform 120 is located on the upper part of the gantry frame, and the universal control wheels 130 are located on the bottom of the gantry frame. The gantry frame and the frame platform form the main frame structure of the gantry system assembly, which is used to install and set up the assembly equipment assembly, the vertical assembly system assembly, the track running assembly, the horizontal assembly assembly, and the control system assembly.

[0036] Reference Figure 4 As a preferred technical solution in this embodiment, the assembly equipment assembly 20 includes a base plate 210, fixed push rods 220, and pressure plate 230. The base plate 210 is set on the frame table 120. In this embodiment, there are four fixed push rods 220, which are set in pairs on the top of both ends of the base plate. The fixed push rods can move horizontally. The pressure plate 230 can be driven by the fixed push rods to fix the U-shaped flat tube. In use, the U-shaped flat tube and the L-shaped flat tube are placed on the top of the base plate. The fixed push rods can move horizontally. When the fixed push rods move to abut against the pressure plate, they can fix the bent parts of the U-shaped flat tube and the L-shaped flat tube and correct the bending angle of the flat tube to prevent poor assembly caused by abnormal flat tube angle. In addition, when the fixed push rods move to release the pressure plate, the pressure plate can be removed and the liquid cooling tube product can be taken out.

[0037] Furthermore, the base plate 210 is provided with a contouring limiting groove 211 for placing U-shaped and L-shaped flat tubes. The base plate 210 is also fixed with a clamp 240. The fixing push rod 220 is located at the free moving end of the clamp. In use, the contouring limiting groove matches the outer dimensions of the flat tube and can be used to fix the flat tube. When it is necessary to fix the bent part of the flat tube, the clamp can be driven to drive the fixing push rod to move, thereby pushing the pressure plate to fix the flat tube.

[0038] It should be noted that the fixed push rod can be changed from manual to pneumatic control, which can improve the degree of automation in fixing the flat tube.

[0039] Reference Figure 5 As a preferred technical solution in this embodiment, the vertical assembly system assembly 30 is configured in two groups, and each group of the vertical assembly system assembly includes two cylinder seats 310, a vertical cylinder 320 and a vertical pressure rod 330. The two cylinder seats 310 are symmetrically arranged along the end of the frame platform 120. The vertical cylinder 320 is vertically arranged on the side wall of the cylinder seat. The vertical pressure rod 330 is arranged at the output end of the vertical cylinder in the same group. In use, after the connecting manifold and the outlet manifold are placed on top of the U-shaped flat pipe and the L-shaped flat pipe, the vertical cylinder is activated, driving the vertical pressure rod to move. The vertical pressure rod then drives the connecting manifold and the outlet manifold to press together with the flat pipe, thereby realizing the assembly of the flat pipe and the manifold.

[0040] It should be noted that in this embodiment, the vertical assembly system assembly on one side is fixed, while the vertical assembly system assembly on the other side is movable. In this way, when in use, one end of the U-shaped flat tube and the L-shaped flat tube only needs to be placed below the fixed end of the vertical assembly system assembly, and the position can be adjusted by moving the vertical assembly system assembly on the other side.

[0041] Reference Figure 6 As a preferred technical solution in this embodiment, in order to achieve stable movement of the vertical assembly system assembly on the other side, the track running assembly 40 includes a guide rail 410, a guide block 420 and a movable cylinder 430. The guide rail 410 is fixedly mounted on the base plate 210, the guide block 420 is slidably mounted on the guide rail, and the movable cylinder 430 is mounted on the base plate, with the output end of the movable cylinder connected to the guide block. The movable cylinder is used to drive the guide block to move along the guide rail.

[0042] In addition, in order to limit the displacement limit of the guide block, a limiting baffle 440 is provided on the base plate. The presence of the limiting baffle can limit the movement stroke of the guide block.

[0043] It should be noted that the vertical assembly system assembly 30 on one side of the assembly equipment assembly 20, i.e. the movable vertical assembly system assembly, is set on the guide block 420, while the vertical assembly system assembly on the other side of the assembly equipment assembly, i.e. the immovable vertical assembly system assembly, is set on the base plate 210.

[0044] Reference Figure 7 As a preferred technical solution in this embodiment, the transverse assembly 50 includes a transverse cylinder 510 and a transverse pressure rod 520. The transverse cylinder 510 is mounted on the base plate 210, and the transverse pressure rod 520 is mounted on the output end of the transverse cylinder and works in conjunction with the pressure plate 230. The transverse pressure rod is used to press the water inlet manifold and the L-shaped flat pipe together, that is, to fix the water inlet manifold. In use, the transverse cylinder is used to drive the straight section end of the water inlet manifold and the L-shaped flat pipe to press together, so as to assemble the two.

[0045] Reference Figure 8 As a preferred technical solution in this embodiment, the control system assembly 60 includes an air pipe 610 connected to the vertical cylinder 320, the movable cylinder 430 and the horizontal cylinder 510, and a pneumatic switch 620 for controlling the air supply and deactivation of each cylinder. The air pipe is used to connect to each cylinder, and the pneumatic switch is used to control the air supply and deactivation of each cylinder.

[0046] The present invention also provides a method for assembling a U-shaped liquid cooling tube according to the aforementioned U-shaped liquid cooling tube assembly equipment, comprising the following steps:

[0047] S10: Place the U-shaped flat tube and the L-shaped flat tube in the contour limiting groove of the base plate, align the bent part of the L-shaped flat tube with the bent part of one end of the U-shaped flat tube, and use the fixed push rod to push the pressure plate to fix the bent parts of the U-shaped flat tube and the L-shaped flat tube.

[0048] Specifically, the present invention adopts a scheme of fixing the flat tube and moving the manifold to press and assemble the flat tube. Therefore, in use, the U-shaped flat tube and the L-shaped flat tube need to be placed in the contour limiting groove of the base plate to fix them and make the bent part of the L-shaped flat tube aligned with the bent part of one end of the U-shaped flat tube. Then, the pressure plate is pushed by the fixed push rod to fix the bent parts of the U-shaped flat tube and the L-shaped flat tube.

[0049] S20: Place the connecting manifold at the top of the bend at one end of the U-shaped flat pipe and the top of the bend at the L-shaped flat pipe, and place the outlet manifold at the top of the bend at the other end of the U-shaped flat pipe.

[0050] Specifically, after the U-shaped flat pipe and L-shaped flat pipe are fixed, the connecting manifold is placed at one end of the U-shaped flat pipe to facilitate the assembly and pressing of the connecting manifold with the U-shaped flat pipe and L-shaped flat pipe. The outlet manifold is placed at the top of the other end of the U-shaped flat pipe to facilitate the assembly and pressing of the outlet manifold with the U-shaped flat pipe.

[0051] S30: The vertical assembly system assemblies on both sides are positioned above the connecting manifold and the outlet manifold. Then, the vertical cylinder drives the vertical pressure rod to press the connecting manifold and the outlet manifold downwards for assembly with the U-shaped flat pipe and the L-shaped flat pipe.

[0052] Specifically, the movable vertical assembly system is moved to the top of the connecting manifold and the outlet manifold. Then, the vertical cylinders on both sides are activated, driving the vertical pressure rod to move in the direction of the connecting manifold and the outlet manifold, so as to realize the pressing assembly of the connecting manifold and the outlet manifold with the U-shaped flat pipe and the L-shaped flat pipe.

[0053] S40: Place the inlet manifold at the horizontal end of the L-shaped flat pipe, and use the transverse cylinder to drive the transverse pressure rod to move. The transverse pressure rod then drives the inlet manifold to assemble with the L-shaped flat pipe.

[0054] Specifically, the inlet manifold is placed at the horizontal end of the L-shaped flat pipe. The action of the transverse cylinder drives the action of the transverse pressure rod, which in turn drives the assembly and pressing of the inlet manifold and the L-shaped flat pipe.
