[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0043] Combined with appendix Figure 1-7 This embodiment of a water pump assembly device includes a workbench 1 with an assembly station, where a workpiece is vertically fixed and a bearing cover is located at the upper end of the assembly station; a rotating lifting mechanism 2 is located at the lower end of the assembly station; a pressing and rotating mechanism 3 is located at the upper end of the assembly station; and a circumferential positioning mechanism 4, a shim pressing mechanism 5, and a screw locking mechanism 6 are provided around the assembly station on the workbench 1.

[0044] The working principle of this water pump assembly equipment is as follows: The barrel equipped with the bearing cover is placed on the rotary lifting mechanism 2. The rotary lifting mechanism 2 lifts the barrel and the bearing cover. Then, the circumferential positioning mechanism 4 confirms its circumferential position so that the hole on the barrel is aligned with the shim pressing mechanism 5. After the shim is pressed into the hole by the shim pressing mechanism 5, the barrel rotates a certain angle so that the hole with the shim is aligned with the screw locking mechanism. The screw is then screwed into the hole to lock the barrel and the bearing cover. The rotary lifting mechanism 2 and the pressing and rotating mechanism 3 work together to press the barrel and the bearing cover together, ensuring the stability during assembly.

[0045] This water pump assembly equipment can automatically connect and fix the barrel and bearing cover, and ensure the stability during assembly, thereby improving the assembly effect. The water pump assembly is highly efficient and requires less manual labor.

[0046] As an optional embodiment of the present invention, the rotary lifting mechanism 2 includes a base 21 located at the lower end of the assembly station and a lifting servo motor 22 for controlling the rotation and lifting of the base. The lifting servo motor 22 is mounted on the workbench 1, and the output shaft of the lifting servo motor 22 is vertically upward. The base 21 is connected to the output end of the lifting servo motor 22.

[0047] As an optional embodiment of the present invention, the pressing and rotating mechanism 3 includes an upper pressing block 31 disposed at the upper end of the assembly station and a fourth driving member 32 for controlling the rotation of the upper pressing block 31. The fourth driving member 32 is a motor. The upper pressing block 31 abuts against the bearing cover at the upper end of the barrel and rotates synchronously with the base 21.

[0048] As an optional embodiment of the present invention, the gasket pressing mechanism 5 includes a gasket positioning plate 51 with a gasket positioning structure; a gasket feeding pipe 52 connected to the gasket positioning plate 51 for providing a gasket to the gasket positioning plate 51, wherein one gasket is provided each time; a gasket push rod 52 spaced apart from the gasket positioning plate 51 along a first direction radially to the assembly station, wherein the front end size of the gasket push rod 52 is adapted to the inner diameter of the gasket; and a first driving member 53 for controlling the gasket push rod 52 to move back and forth along the first direction. When the gasket push rod 52 moves along the first direction toward the assembly station, the gasket push rod 52 pushes a single gasket on the gasket positioning plate 51 into a hole on the barrel, and then the gasket push rod 52 retracts and leaves the gasket in the hole of the barrel.

[0049] As an optional embodiment of the present invention, the first driving component 53 is a servo electric cylinder, and the output shaft of the servo electric cylinder is arranged along the first direction.

[0050] As an optional embodiment of the present invention, the gasket positioning structure includes a gasket positioning groove 51a, a gasket push rod inlet, and a gasket feed port 51b disposed within the gasket positioning plate 51. Both the gasket push rod inlet and the gasket feed port 51b are connected to the gasket positioning groove 51a. The diameter of the gasket push rod inlet is larger than the gasket's diameter but smaller than its outer diameter. The diameter of the gasket positioning groove 51a is equal to the outer diameter of the gasket. The gasket feed port 51b is located at the upper end of the gasket positioning groove 51a and connected to the gasket feed pipe 52. The gasket positioning plate 51 includes a first gasket positioning plate 511 and a second gasket positioning plate 512 spaced apart along a second direction. The first direction and the second direction are perpendicular. Both the gasket positioning groove 51a and the gasket push rod inlet are located within the gasket positioning plate 51a. Between the first gasket positioning plate 511 and the second gasket positioning plate 512, the gasket pressing mechanism 5 further includes a first control structure for controlling the opening and closing of the first gasket positioning plate 511 and the second gasket positioning plate 512 in the second direction; when the first gasket positioning plate 511 and the second gasket positioning plate 512 separate, the gasket positioning groove 51a is fully opened, and the separation time of the first gasket positioning plate 511 and the second gasket positioning plate 512 is when the gasket push rod 52 extends into the gasket through the gasket push rod inlet. At this time, the first gasket positioning plate 511 and the second gasket positioning plate 512 separate so that the gasket push rod 52 continues to move forward to push the gasket to the assembly station, avoiding collision between the gasket and the gasket positioning plate 51.

[0051] As an optional embodiment of the present invention, the outlet of the gasket feed pipe 52 is located directly above the gasket feed port 51b and is not directly connected to the gasket positioning plate 51. The gasket feed pipe 52 does not move when the first gasket positioning plate 511 and the second gasket positioning plate 512 are separated.

[0052] As an optional embodiment of the present invention, the first control structure includes a first sliding plate 54 connected to the first gasket positioning plate 511; a second sliding plate 55 connected to the second gasket positioning plate 512; a first sliding groove 54a disposed on the first sliding plate 54 and extending along the first direction; a second sliding groove 55a disposed on the second sliding plate 55 and extending along the first direction; and a sliding rod 56 disposed in the first sliding groove 54a and the second sliding groove 55a respectively and connected to the gasket push rod 52; the first sliding plate 54 and the second sliding plate 55 are slidably connected to the worktable 1 along the second direction via a sliding rail, and the distance between the first sliding groove 54a and the second sliding groove 55a in the second direction is closer to the gasket. The smaller the positioning plate 51, the closer the distance between the first sliding groove 54a and the second sliding groove 55a in the second direction is to the larger the first driving member 53. When the sliding rod 56 moves towards the gasket positioning plate 51 along with the gasket push rod 52, the sliding rod 56 will push the first sliding plate 54 and the second sliding plate 55 to both sides, thereby controlling the opening and closing action of the first gasket positioning plate 511 and the second gasket positioning plate 512. It can also ensure that when the gasket push rod 52 contacts the gasket, the first gasket positioning plate 511 and the second gasket positioning plate 512 are just in the initial stage of separation, which can prevent the gasket from falling off the gasket positioning plate 51 and prevent the gasket from colliding with the gasket positioning plate 51.

[0053] As an optional embodiment of the present invention, the screw locking mechanism 6 includes a screw gun head 61 with a screw positioning structure; a screw feed tube 62 connected to the screw gun head 61, through which screws enter the screw gun head 61 for use, with one screw entering the screw gun head 61 at a time; a screw push rod 63 arranged in a third direction along the radial direction of the assembly station; a screwdriver head 64 disposed in the screw gun head 61 and connected to the screw push rod 63; and a second driving member 65 for controlling the screw push rod 63 to move back and forth and rotate synchronously along the third direction; the screwdriver head 64 rotates to push the screw out of the screw gun head 61 and tighten it into the hole of the barrel to achieve a locking connection between the barrel and the bearing cover.

[0054] As an optional embodiment of the present invention, the screw positioning structure includes a screw driving channel 61a, a screw ejection port 61b, and a screw feeding port 61c disposed within the screw gun head 61. The screw driving channel 61a extends along the third direction. The screw ejection port 61b and the screw feeding port 61c are both connected to the screw driving channel 61a. The screw ejection port 61b is disposed at one end of the screw driving channel 61a away from the screw push rod 63. The screw feeding port 61c is disposed at the upper end of the screw driving channel 61a and connected to the screw feeding tube 62. The screwdriver head 64 is disposed within the screw driving channel 61a and can move back and forth along the screw driving channel 61a. The screwdriver head 64 can rotate and eject the screw from the screw ejection port 61b.

[0055] As an optional embodiment of the present invention, the second driving member 65 may be a combination structure of a cylinder and a motor to control the screw push rod 63 to move back and forth and rotate synchronously along the third direction. The motor is used to control the rotation of the screw push rod 63, and the cylinder is used to control the motor and the screw push rod 63 to move back and forth synchronously along the third direction.

[0056] As an optional embodiment of the present invention, it further includes an upper protective sleeve 7 disposed at the upper end of the assembly station and a third driving member 8 for controlling the upper protective sleeve 7 to move back and forth along the axial direction of the assembly station. The upper protective sleeve 7 is sleeved outside the upper pressure block 31 and can move relative to it. The upper protective sleeve 7 can move downward to sleeve the upper end of the machine barrel, so that when there is a gasket in the hole of the machine barrel, rotating the machine barrel causes the gasket to fall out of the hole. When the machine barrel is not rotating, the upper protective sleeve 7 moves upward to disengage from the machine barrel.

[0057] As an optional embodiment of the present invention, the third driving component 8 is a cylinder.

[0058] As an optional embodiment of the present invention, the circumferential positioning mechanism 4 includes a distance measuring module and a vision positioning module. The distance measuring module is used to measure the distance between the bearing cover and the workpiece, and the vision positioning module is used to acquire images of the holes on the workpiece. There is a notch on the outer circumference of the bearing cover (the bearing cover of the water pump barrel is provided with this notch). The position of the notch can be detected by measuring the distance between the bearing cover and the distance measuring module, thereby adjusting the circumferential position of the barrel and the bearing cover. Then, the vision positioning module takes an image of the hole on the outer circumferential wall of the barrel to determine whether the barrel positioning is accurate. If it is inaccurate, it is repositioned. If the position is accurate, it should be consistent with the hole position on the standard image (the standard image is a picture taken when the barrel position is accurate).

[0059] As an optional embodiment of the present invention, it further includes a feeding track 9 disposed on the worktable 1. The feeding track 9 is provided with a loading position 9a, a processing position 9b, and a unloading position 9c. The rotary lifting mechanism 2 is disposed at the processing position 9b. The processing position 9b is provided with a mounting hole that matches the base 21. The base 21 can rise upward from the mounting hole. The feeding track 9 is provided with a first gripper 10 that moves back and forth between the loading position 9a, the processing position 9b, and the unloading position 9c. In order to prevent the workpiece placed manually at the loading position 9a from colliding with the unloading workpiece, the feeding track 9 is also provided with a buffer position 9d. The feeding track 9 is also provided with a second gripper 11 that moves back and forth between the loading position 9a and the buffer position 9d. The operator only needs to place the workpiece to be processed at the buffer position 9d. After unloading is completed, the second gripper 11 automatically moves the workpiece at the buffer position 9d to the loading position 9a.

[0060] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
