DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figure 1-4 As shown, the automatic upper cover installation mechanism of the present invention includes: a lower frame 1; a jig 2, on which a pump body is mounted; a fixed bracket 3, which is mounted on the lower frame 1; an adjustable bracket 4, which is mounted on the fixed bracket 3; a membrane-moving clamping cylinder 5, which is mounted on the adjustable bracket 4. The adjustable bracket 4 is used to adjust the relative position between the membrane-moving clamping cylinder 5 and the jig 2. The membrane-moving clamping cylinder 5 is provided with two clamping jaws, and the clamping jaws of the membrane-moving clamping cylinder 5 are connected to a lever 6. The membrane-moving clamping cylinder 5 drives the lever 6 to move the diaphragm on the pump body; a manipulator 7, which is mounted on the lower frame 1. The manipulator 7 is used to grab the upper cover and install the upper cover on the pump body after the lever 6 has moved the diaphragm. The lever 6 is a thin cylindrical rod.

[0019] In the above structure, a conveyor line 8 is provided on the lower frame 1 , and the conveyor line 8 is used to convey the jig 2 .

[0020] In the above structure, a lifting device 9 is provided on the lower frame 1, and the lifting device 9 is used to lift the fixture 2 on the conveyor line 8 to the assembly station.

[0021] In the above structure, the robot arm 7 is provided with a sensor bracket 10 , and the sensor bracket 10 is provided with a laser sensor 101 . The laser sensor 101 is used to detect the upper cover on the robot arm 7 .

[0022] In the above structure, the manipulator 7 includes a manipulator bracket 71, an X-axis servo module 72, a Z-axis servo module 73, and a cover clamping cylinder 74. The manipulator bracket 71 is fixedly mounted on the lower frame 1, the X-axis servo module 72 is fixedly mounted on the manipulator bracket 71, the Z-axis servo module 73 is connected to the slider of the X-axis servo module 72, and the cover clamping cylinder 74 is connected to the slider of the Z-axis servo module 73. The X-axis servo module 72 and the Z-axis servo module 73 cooperate with each other to drive the cover clamping cylinder 74 to switch between the cover loading position and the cover assembly position. The cover clamping cylinder 74 is connected to two symmetrically arranged cover clamping jaws, and the cover clamping jaws of the cover clamping cylinder 74 are used to load the cover. The sensor bracket 10 is mounted on the cover clamping cylinder 74, and the signal output end of the laser sensor 101 is arranged directly between the cover clamping jaws of the cover clamping cylinder 74. The X-axis servo module 72 and the Z-axis servo module 73 utilize conventional linear modules, a mechanical device for achieving linear motion. They primarily consist of guide rails, sliders, a drive device (such as a motor or cylinder), and necessary lubrication and support structures. Their core function is to convert rotational motion into linear motion, or directly achieve stable and precise linear movement. Structurally, linear modules typically utilize a design that combines guide rails and sliders. Guide rails are typically made of sturdy materials such as aluminum alloy and stainless steel to ensure excellent strength and wear resistance. Sliders slide in conjunction with the guide rails, ensuring smooth and precise motion. Drive devices, such as stepper motors, servo motors, or cylinders, are selected based on specific needs. The design of linear modules emphasizes smoothness, precision, and repeatability, adapting to a variety of working environments. Their emergence has greatly simplified the structural design of mechanical motion systems and improved the reliability and efficiency of automated equipment.

[0023] Reference Figure 5 As shown, the upper cover clamping jaw cylinder 74 is connected to an L-shaped mounting plate 741, which is provided with a positioning sleeve 742. The jig 2 comprises a jig base 21 and a pump body mounting base 22. The pump body mounting base 22 is fixedly mounted on the jig base 21 and is used to place the pump body. The pump body mounting base 22 is provided with a positioning pin 221, and the positioning sleeve 742 is inserted into the positioning pin 221 to achieve positioning during the assembly of the upper cover and pump body.

[0024] In the above structure, the lifting device 9 includes a lifting power source 91 and a push plate 92. The push plate 92 is connected to the output end of the lifting power source 91. The lifting power source 91 drives the push plate 92 to separate the lifting fixture 2 from the conveyor line 8. The lifting power source 91 can be an electric cylinder or a pneumatic cylinder.

[0025] The working principle of the automatic installation mechanism of the upper cover of the present invention is: After the fixture 2 is in place, the power source 91 is lifted up. After the pallet is positioned, the two small round rods on the mechanism are opened to open the soft membranes on the left and right breathable membranes on the motor to the outside. The floating grasping mechanism first takes the upper cover from the pallet, and then installs the upper cover on the motor shaft through the X-axis servo module 72 and the Z-axis servo module 73. The opening mechanism retracts and the floating grasping mechanism returns to the origin.

[0026] By simulating the characteristics of manual assembly, a spreading mechanism is designed to spread the soft films on the left and right breathable membranes outward, creating space for effective and interference-free installation of the top cover. The top cover is then effectively installed on the motor shaft through a floating gripping mechanism. The floating unit can accommodate product size differences and achieve effective automated assembly.

[0027] The upper cover gripper cylinder 74 and the membrane-pushing gripper cylinder 5 utilize gripper cylinders. These gripper cylinders are mechanical components powered by air pressure and are primarily used for fast and precise gripping of items in automated industrial production lines. The gripper cylinder's interior primarily consists of a piston, a slide valve, a guide rod, and gripper jaws. Their operating principle is as follows: when air pressure is applied to one inlet (input port), gas enters the gripper cylinder and pushes the piston in the corresponding direction, thereby opening or closing the gripper jaws. When the air pressure is lost from the inlet port, the other inlet (input port) receives air pressure, causing gas to flow into the gripper cylinder and push the piston back to its initial position.

[0028] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
