Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and more specifically to an OBC vehicle charger water nozzle assembly system. Background Technology

[0002] An on-board charger is a charger that is fixedly installed on an electric vehicle. It has the ability to provide power to the electric vehicle and is an indispensable component of new energy vehicles. However, on-board chargers generate a lot of heat when they are working. In order to prevent damage to the charger, cooling pipes are usually installed in the on-board charger to cool it. The water nozzles of the cooling pipes are located on the side wall of the on-board charger. Currently, it is usually necessary to manually lubricate the water nozzles, align them with the housing mounting opening, and assemble the water nozzles to the housing by stamping. This manual pressing is not only inefficient, but the assembly quality is also easily affected by the operator's skill level, and there are significant safety hazards in operation.

[0003] Chinese patent CN206795194U discloses a faucet installation device. The device involves mounting a housing onto the faucet installation device, then a gripping component moves from its initial position along the X-direction towards an alignment component, gripping the curved portion of the faucet and returning to its initial position along the X-direction, thus bringing the faucet back to its initial position. The gripping component then moves along the Y-direction to a position opposite the housing, aligning the mounting end of the faucet with the faucet opening of the housing. The gripping component then moves along the X-direction towards the housing, pressing the faucet into the faucet opening of the housing. After the faucet is pressed into the faucet opening, the gripping component returns to its initial position. This installation method is inefficient, requires manual operation, has low automation, and involves cumbersome steps. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an OBC vehicle charger water nozzle assembly system. When the charger slides on the slide rail to the drive component, the drive component drives the charger to rise. Then, the robotic arm grabs the water nozzle and places it in the assembly plate for positioning. The lubrication component lubricates the water nozzle and then assembles it with the housing. Subsequently, the drive component drives the charger to rotate 180° and installs another water nozzle, which greatly improves the assembly efficiency while ensuring the water nozzle assembly quality.

[0005] The technical solution of the present invention is as follows:

[0006] An OBC vehicle charger water nozzle assembly system includes a workbench, a slide rail mounted on the workbench, and a tray slidably mounted on the slide rail. A drive component is mounted on the workbench, and an assembly assembly is mounted on one side of the drive component. The assembly assembly includes an assembly plate for supporting the water nozzle. A rotating component and a guide component driven by the rotating component are mounted on the assembly assembly. A lubrication component is mounted on the guide component. The lubrication component includes a locking sleeve and several cylinders disposed within the locking sleeve for holding lubricant. The drive component drives the charger, placed on the tray, to lift, lower, and rotate. The rotating component drives the guide component to rotate. The lubrication component, after the locking sleeve engages with the water nozzle, applies the lubricant from the cylinders to the water nozzle under the action of the guide component. The assembly assembly drives the water nozzle to assemble with the charger.

[0007] As a preferred embodiment, the assembly assembly further includes a base fixedly mounted on the workbench, a sliding plate slidably mounted on the base, and a screwdriver fixedly mounted on the sliding plate, wherein the assembly plate is fixedly mounted on the sliding plate.

[0008] As a preferred embodiment, the rotating assembly includes a fixed seat fixedly mounted on the base, a sliding seat slidably mounted on the fixed seat, a motor fixedly mounted on the sliding seat, and a first gear fixedly mounted on the motor output shaft.

[0009] As a preferred embodiment, the guide assembly includes a fixed sleeve fixedly mounted on a sliding seat, a rotating sleeve slidably mounted on the fixed sleeve, a second gear fixedly mounted on the rotating sleeve, a groove formed on the rotating sleeve, and a plurality of sliders fixedly mounted on the rotating sleeve, wherein the first gear meshes with the second gear.

[0010] As a preferred embodiment, the lubrication assembly further includes several through slots formed on the locking sleeve, a piston slidably disposed within the cylinder, a piston rod fixedly disposed on the piston, a liquid outlet pipe fixedly disposed on the cylinder, an arc-shaped plate fixedly disposed on the liquid outlet pipe, through holes formed on the arc-shaped plate, and a liquid inlet pipe fixedly disposed on the cylinder. The slider cooperates with the through slots, the arc-shaped plate cooperates with the water nozzle, and the liquid inlet pipe passes through the rotating sleeve and connects to the fixed sleeve.

[0011] As a preferred embodiment, the slide groove consists of an ascending section and a descending section, and the bottom of the piston rod is spherical and fits into the slide groove.

[0012] As a preferred option, a robotic arm is also provided on the worktable.

[0013] As a preferred embodiment, both the inlet pipe and the outlet pipe are equipped with one-way valves.

[0014] As a preferred embodiment, the assembly plate is provided with a rubber layer.

[0015] As a preferred embodiment, the curved plate is made of a flexible material.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention is equipped with an assembly component. After the robotic arm grasps the water nozzle, it places the water nozzle in the assembly plate for positioning, which replaces the manual installation of the water nozzle and improves the assembly quality of the water nozzle. After the water nozzle is lubricated, the sliding plate drives the water nozzle to assemble with the charger, and the water nozzle is fixed by the screw machine, which improves the assembly efficiency of the water nozzle.

[0018] 2. This invention includes a lubrication assembly. By rotating the rotating sleeve, the lubricant inside the cylinder is applied to the water nozzle through the arc-shaped plate. This simplifies the water nozzle lubrication structure and avoids wasting lubricant. As the rotating sleeve continues to rotate, it causes the arc-shaped plate to rotate around the water nozzle, ensuring that the lubricant is evenly applied to the water nozzle and improving the installation effect. Furthermore, after the water nozzle is lubricated, the rotating sleeve reverses and drives the piston rod and piston to rise, which can draw the lubricant in the fixed sleeve into the cylinder to prepare for the next lubrication. This automatic replenishment action improves lubrication efficiency.

[0019] In summary, this invention has the advantages of high assembly quality and fast assembly efficiency, and is suitable for the field of automotive parts manufacturing technology. Attached Figure Description

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figures 1 to 11As shown, an OBC vehicle charger water nozzle assembly system includes a workbench 1, a slide rail 2 mounted on the workbench 1, and a tray 3 slidably mounted on the slide rail 2. A drive component 4 is mounted on the workbench 1, and an assembly assembly 5 is mounted on one side of the drive component 4. The assembly assembly 5 includes an assembly plate 53 for supporting the water nozzle 10. A rotating component 6 and a guide component 7 driven by the rotating component 6 are mounted on the assembly assembly 5. A lubrication component 8 is mounted on the guide component 7, and the lubrication component 8 includes a locking sleeve 81 and a lubrication device disposed within the locking sleeve 81. The device comprises several cylinders 82 for holding lubricant. The drive component 4 is used to drive the charger 9 placed on the tray 3 to lift and rotate. The rotating component 6 is used to drive the guide component 7 to rotate. The lubrication component 8 is used to apply the lubricant in the cylinder 82 to the water nozzle 10 under the action of the guide component 7 after the engaging sleeve 81 engages with the water nozzle 10. The assembly component 5 is used to drive the water nozzle 10 to assemble with the charger 9. After the water nozzle 10 on one side of the charger 9 is installed, the drive component 4 drives the charger 9 to rotate 180° to assemble the other side.

[0037] like Figure 1 and Figure 11 As shown, the assembly assembly 5 also includes a base 51 fixedly mounted on the workbench 1, a sliding plate 52 slidably mounted on the base 51, and a screwdriver 54 fixedly mounted on the sliding plate 52. The assembly plate 52 is fixedly mounted on the sliding plate 52. A drive device is connected to the sliding plate 52 to drive the sliding plate 52 to move. In use, the robot arm 13 grabs the water nozzle 10 and places the water nozzle 10 in the assembly plate 53 for positioning, which replaces the manual installation of the water nozzle 10 and improves the assembly quality of the water nozzle 10. After the water nozzle 10 is lubricated, the sliding plate 52 drives the water nozzle 10 to assemble with the charger 9, and the screwdriver 54 fixes the water nozzle 10, which greatly improves the assembly efficiency and achieves the effect of automated assembly.

[0038] like Figure 3 and Figure 11 As shown, the rotating assembly 6 includes a fixed seat 61 fixedly mounted on the base 51, a sliding seat 62 slidably mounted on the fixed seat 61, a motor 63 fixedly mounted on the sliding seat 62, and a first gear 64 fixedly mounted on the output shaft of the motor 63. A cylinder is connected to the sliding seat 62 to drive the sliding seat 62 to move up and down. When the robot arm 13 places the water nozzle 10 on the assembly plate 53, the cylinder drives the sliding seat 62 to rise, making the engaging sleeve 81 coaxial with the water nozzle 10. The sliding plate 52 drives the water nozzle 10 to move forward and engage with the engaging sleeve 81 for lubrication. After lubrication is completed, the sliding plate 52 drives the water nozzle 10 to move backward and reset, disengaging from the engaging sleeve 81. The cylinder drives the sliding seat 62 to descend and reset, preventing interference with the assembly of the water nozzle 10 and the charger 9.

[0039] like Figure 4 and Figure 10As shown, the guide assembly 7 includes a fixed sleeve 71 fixedly mounted on the sliding seat 62, a rotating sleeve 72 slidably mounted on the fixed sleeve 71, a second gear 73 fixedly mounted on the rotating sleeve 72, a groove 74 formed on the rotating sleeve 72, and a plurality of sliders 75 fixedly mounted on the rotating sleeve 72. The first gear 64 meshes with the second gear 73. A pipe is connected to the fixed sleeve 71, and lubricant enters the fixed sleeve 71 through the pipe, so that the fixed sleeve 71 is always filled with lubricant.

[0040] like Figures 6 to 10 As shown, the lubrication assembly 8 also includes several through slots 83 formed on the engaging sleeve 81, a piston 84 slidably disposed within the cylinder 82, a piston rod 85 fixedly disposed on the piston 84, a liquid outlet pipe 86 fixedly disposed on the cylinder 82, an arc-shaped plate 87 fixedly disposed on the liquid outlet pipe 86, a through hole 88 formed on the arc-shaped plate 87, and a liquid inlet pipe 89 fixedly disposed on the cylinder 82. The slider 75 cooperates with the through slots 83, the arc-shaped plate 87 cooperates with the water nozzle 10, and the liquid inlet pipe 89 passes through the rotating sleeve 72 and connects to the fixed sleeve 71. In use, after the water nozzle 10 is placed in the assembly plate 53, the cylinder drives the sliding seat 62 to rise until the engaging sleeve 81 and the water nozzle 10 are coaxial. Then, the sliding plate 52 drives the water nozzle 10 to approach the engaging sleeve 81 until it engages with it. Subsequently, the motor 63 drives the first gear 64 and the second gear 73 to rotate. The second gear 73 drives the rotating sleeve 72 to rotate, and the rotating sleeve 72 drives the sliding seat 62 to rotate. As the groove 74 rotates, the piston rod 85 moves from the rising section 11 into the falling section 12, causing the piston 84 to descend. This forces the lubricant in the cylinder 82 to be squeezed from the outlet pipe 86 into the arc plate 87 and then extruded through the through hole 88 onto the nozzle 10. Simultaneously, the rotating sleeve 72 drives the sliding groove 74 to rotate, causing the piston rod 85 to pass through the falling section 12. The rotating sleeve 72 then drives the slider 75 to slide from one end of the through groove 83 to the other. As the rotating sleeve 72 continues to rotate, it causes the engaging sleeve 81 and the arc plate 87 to rotate around the nozzle 10, evenly coating the nozzle 10 with lubricant and improving lubrication. After lubrication is complete, the motor 63 drives the first gear 64 and the second gear 73 to reverse direction. The rotating sleeve 72 then drives the sliding groove 74 to reverse direction, causing the piston rod 85 to move from the falling section 12 into the rising section 11, causing the piston 84 to rise. This draws the lubricant in the fixed sleeve 71 into the cylinder 82 through the inlet pipe 89, preparing for the next lubrication cycle.

[0041] like Figure 7 As shown, the slide 74 consists of an ascending section 11 and a descending section 12, and the bottom of the piston rod 85 is spherical and cooperates with the slide 74.

[0042] like Figure 1 As shown, a robotic arm 13 is also installed on the workbench 1 to improve assembly efficiency.

[0043] like Figure 11As shown, both the inlet pipe 89 and the outlet pipe 86 are equipped with one-way valves to ensure that the lubricant in the inlet pipe 89 can only enter and not exit, and the lubricant in the outlet pipe 86 can only exit and not enter.

[0044] like Figure 1 As shown, the assembly plate 53 is provided with a rubber layer. When the robot arm 13 places the water nozzle 10 into the assembly plate 53, it prevents damage to the water nozzle 10 and protects the water nozzle 10.

[0045] Example 2

[0046] like Figure 1 As shown, the components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that the arc plate 87 is made of a flexible material.

[0047] In this embodiment, the curved plate 87 is made of a flexible material, which makes it fit more tightly with the water tap 10 without damaging the water tap 10.

[0048] Work process:

[0049] After the robotic arm 13 grasps the water nozzle 10, it places the water nozzle 10 within the assembly plate 53 for positioning. Then, the cylinder drives the sliding seat 62 to rise until the engaging sleeve 81 is coaxial with the water nozzle 10. The sliding plate 52 moves the water nozzle 10 closer to the engaging sleeve 81 until it engages. Subsequently, the motor 63 drives the first gear 64 and the second gear 73 to rotate. The second gear 73 drives the rotating sleeve 72 to rotate, which in turn drives the sliding groove 74 to rotate. The piston rod 85 moves from the rising section 11 to the descending section 12, causing the piston 84 to descend. This forces the lubricant inside the cylinder 82 to be squeezed from the outlet pipe 86 into the arc-shaped plate 87 and then extruded onto the water nozzle 10 through the through hole 88. Furthermore, in the rotating sleeve 7... 2. The rotating sleeve 72 drives the slide 74 to rotate, causing the piston rod 85 to pass through the descending section 12. At the same time, the rotating sleeve 72 drives the slider 75 to slide from one end of the through groove 83 to the other end. Then, as the rotating sleeve 72 continues to rotate, it drives the locking sleeve 81 and the arc plate 87 to rotate around the water nozzle 10, so that the lubricant is evenly applied to the water nozzle 10 to improve the lubrication effect. After the lubrication is completed, the motor 63 drives the first gear 64 and the second gear 73 to reverse. The rotating sleeve 72 drives the slide 74 to reverse, so that the piston rod 85 enters the ascending section 11 from the descending section 12 and drives the piston 84 to rise. The lubricant in the fixed sleeve 71 is drawn into the cylinder 82 through the liquid inlet pipe 89 to prepare for the next lubrication.
