[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0022] Reference Figures 1 to 6 As shown, this utility model provides a pump accessory assembly machine.

[0023] The pump parts assembly machine includes a frame 10, a rotating mechanism 100, a pump body conveying trough 200, a dust cover conveying trough 300, a suction pipe assembly mechanism 400, a dust cover pressing mechanism 500, a discharge trough 600, a dust cover baffle 800, a pump body baffle 810, a pump core baffle 820, and a guide plate 900.

[0024] The rotating mechanism 100 is mounted on the frame 10. The rotating mechanism 100 is driven by a rotary motor, which is mounted on the frame 10. The rotating mechanism 100 is connected to the rotary motor, and the rotary motor drives the rotating mechanism 100 to rotate around the vertical axis.

[0025] The pump body conveying trough 200, the dust cover conveying trough 300, the dust cover pressing mechanism 500, and the feeding trough 600 are arranged sequentially along the rotation direction of the rotating mechanism 100.

[0026] The height of the dust cover pressing mechanism 500 is higher than that of the rotating mechanism 100. The suction tube assembly mechanism 400 is located directly below the dust cover pressing mechanism 500 and is lower than that of the rotating mechanism 100. An assembly station 700 is formed between the dust cover pressing mechanism 500 and the suction tube assembly mechanism 400.

[0027] Reference Figure 3 and Figure 6 As shown, a plurality of assembly slots 110 are provided on the outer peripheral surface of the rotating mechanism 100. The plurality of assembly slots 110 are evenly spaced along the circumference of the rotating mechanism 100, and each assembly slot 110 is semi-circular.

[0028] Each assembly slot 110 is divided into a dust cover limiting slot 111, a pump body limiting slot 112, and a pump core limiting slot 113 from top to bottom. The diameter of the pump core limiting slot 113 is smaller than the diameter of the dust cover limiting slot 111, and the diameter of the dust cover limiting slot 111 is smaller than the diameter of the pump body limiting slot 112. Therefore, the top surface of the pump core limiting slot 113 forms a supporting step 114 at the bottom of the pump body limiting slot 112.

[0029] A pump core 1010 is installed at the bottom of the pump body 1000. The diameter of the pump core 1010 is smaller than the diameter of the pump body 1000. The diameter of the dust cover corresponds to the diameter of the dust cover limiting groove 111. The diameter of the pump body 1000 corresponds to the diameter of the pump body limiting groove 112. The diameter of the pump core 1010 corresponds to the diameter of the pump core limiting groove 113. A sleeve is formed above the pump core 1010 in the pump body 1000. When the pump body 1000 is set in the pump body limiting groove 112, the pump core 1010 is set in the pump core limiting groove 113. The bottom of the sleeve abuts against the supporting step 114.

[0030] A circumferentially extending clearance groove 120 is also provided on the outer peripheral surface of the rotating mechanism 100. The clearance groove 120 surrounds the outer periphery of the rotating mechanism 100 and passes through all the assembly grooves 110. The clearance groove 120 is located between the pump body limiting groove 112 and the pump core limiting groove 113.

[0031] The pump body conveying groove 200 is connected to the frame 10. The pump body conveying groove 200 is located on the periphery of the rotating mechanism 100. The height of the pump body conveying groove 200 is the same as the height of the pump body limiting groove 112. When the assembly groove 110 rotates to the pump body conveying groove 200 with the rotating mechanism 100, the pump body conveying groove 200 conveys the pump body 1000 into the pump body limiting groove 112 of the assembly groove 110. The pump core 1010 falls into the pump core limiting groove 113, and the sleeve of the pump body 1000 abuts against the supporting step 114.

[0032] The pump core baffle 820 is connected to the frame 10 and is located on the periphery of the rotating mechanism 100. The pump core baffle 820 is arc-shaped, and its height is the same as that of the pump core limiting groove 113. The pump core baffle 820 extends along the rotation direction of the rotating mechanism 100. One end of the pump core baffle 820 is connected to the pump body conveying groove 200, and the other end extends above the discharge groove 600.

[0033] The diameter of the pump core limiting groove 113 is equal to the distance between the axis of the pump core baffle 820 and the assembly groove 110. Thus, a pump core limiting structure is formed between the pump core baffle 820 and the pump core limiting groove 113. The pump core limiting structure restricts the degree of freedom of the pump core 1010 in the horizontal direction to ensure that the pump body 1000 is smoothly transported from the pump body conveying groove 200 to the unloading groove 600, and to prevent the pump body 1000 from falling during the conveying process.

[0034] The dust cover conveying trough 300 is connected to the frame 10. The dust cover conveying trough 300 is located on the periphery of the rotating mechanism 100. The height of the dust cover conveying trough 300 is the same as the height of the dust cover limiting groove 111. When the assembly groove 110 rotates from the pump body conveying trough 200 to the dust cover conveying trough 300 with the rotating mechanism 100, the dust cover conveying trough 300 conveys the dust cover into the dust cover limiting groove 111 of the assembly groove 110. Since the diameter of the dust cover corresponds to the diameter of the dust cover limiting groove 111, the degree of freedom of the dust cover to translate in the dust cover limiting groove 111 is restricted, so that the dust cover falls on the top of the pump body 1000 in the dust cover limiting groove 111.

[0035] The dust cover baffle 800 is connected to the frame 10. The dust cover baffle 800 is located on the periphery of the rotating mechanism 100. The dust cover baffle 800 is arc-shaped. The height of the dust cover baffle 800 is the same as the height of the dust cover limiting groove 111. The dust cover baffle 800 extends along the rotation direction of the rotating mechanism 100. One end of the dust cover baffle 800 is connected to the dust cover conveying groove 300, and the other end of the dust cover baffle 800 extends to the assembly station 700.

[0036] The diameter of the dust cover limiting groove 111 is equal to the distance between the dust cover baffle 800 and the axis of the assembly groove 110. Thus, a dust cover limiting structure is formed between the dust cover baffle 800 and the dust cover limiting groove 111. The dust cover limiting structure restricts the degree of freedom of the dust cover in the horizontal direction to ensure that the dust cover is smoothly transported from the dust cover conveying groove 300 to the assembly station 700, and to prevent the dust cover from falling off during the transport process.

[0037] Reference Figure 2As shown, the suction tube assembly mechanism 400 is located below the rotating mechanism 100. The suction tube assembly mechanism 400 includes a lifting mechanism, multiple assembly heads 410 and multiple cutting mechanisms, with each of the multiple cutting mechanisms corresponding to the top of the multiple assembly heads 410.

[0038] A lifting mechanism is installed on the frame 10 and is connected to the assembly head 410. The lifting mechanism drives the assembly head 410 to move in the vertical direction, causing the assembly head 410 to move upward toward the assembly station 700 or downward away from the assembly station 700. The assembly head 410 includes a chuck, a cylinder, and a conveying channel. The conveying channel is arranged in a vertical direction and is used to convey the suction tube. The side wall of the conveying channel is provided with a through slot. The chuck is slidably arranged in the slot. The cylinder drives the chuck to move along the slot. The chuck moves along the slot toward the conveying channel to clamp the suction tube. The chuck moves away from the conveying channel along the slot to release the suction tube.

[0039] Each assembly head 410 is equipped with a cutting mechanism at its top. The cutting mechanism includes a cylinder, a slide rail, and a cutter. The slide rail is arranged horizontally, and the cutter is slidably arranged in the slide rail. The cylinder is connected to the cutter and drives the cutter to move along the slide rail. The movement trajectory of the cutter coincides with the upper part of the conveying channel. The cylinder drives the cutter to move upwards in the conveying channel to cut off the suction tube. The cylinder drives the cutter to return to its original position to avoid the upwardly conveyed suction tube.

[0040] The rotating mechanism 100 moves the pump body 1000 of the assembly tank 110 to the assembly station 700, so that the assembly tank 110 is above the assembly head 410. The assembly head 410 drives the chuck to clamp the suction tube, and the lifting mechanism drives the assembly head 410 to move upward, causing the suction tube to move upward, so that the top of the suction tube is inserted into the bottom of the pump core 1010. Then the assembly head 410 drives the chuck to release the suction tube, and the lifting mechanism drives the assembly head 410 to move downward. When the lifting mechanism and the assembly head 410 drive the cutting mechanism to descend to the preset position, the lifting mechanism pauses and starts the cutting mechanism, causing the cylinder to drive the cutter to move towards the suction tube to cut the suction tube. Then the cylinder drives the cutter to return to the original position. Finally, the lifting mechanism continues to drive the assembly head 410 to move downward to the designated position. Therefore, the above process is repeated continuously to ensure that the assembly head 410 can deliver the suction tube upward segment by segment.

[0041] Reference Figure 2As shown, the dust cover pressing mechanism 500 is connected to the frame 10. The dust cover pressing mechanism 500 is located on the top of the rotating mechanism 100. The dust cover pressing mechanism 500 is equipped with multiple linear push rods and multiple pressing heads 510. The multiple linear push rods are positioned directly above the multiple assembly heads 410. The multiple pressing heads 510 are connected to the multiple linear push rods. The linear push rods drive the pressing heads 510 to move in the up and down direction. The linear push rods drive the pressing heads 510 to move downward and extend into the assembly station 700. The linear push rods drive the pressing heads 510 to move upward and away from the assembly station 700.

[0042] Reference Figure 3 and Figure 6 As shown, the pump body baffle 810 is installed on top of the pump core baffle 820. The pump body baffle 810 is located between the pump core baffle 820 and the dust cover baffle 800. The pump body baffle 810 is located on the periphery of the rotating mechanism 100. The pump body baffle 810 is arc-shaped. The height of the pump body baffle 810 is the same as the height of the pump body limiting groove 112. The pump body baffle 810 extends along the rotation direction of the rotating mechanism 100. One end of the pump body baffle 810 extends to the assembly station 700, and the other end of the pump body baffle 810 extends above the discharge chute 600.

[0043] The diameter of the pump body 1000 is equal to the distance between the axis of the pump body baffle 810 and the assembly groove 110. Thus, a pump body limiting structure is formed between the pump body baffle 810 and the pump body limiting groove 112. The pump body limiting structure restricts the degree of freedom of the pump body 1000 in the horizontal direction. During the process of the dust cover pressing mechanism 500 pressing the dust cover against the pump body 1000 and the suction pipe assembly mechanism 400 assembling the suction pipe to the pump core 1010, the pump body limiting structure ensures that the position of the pump body 1000 is fixed. After the assembly is completed, the pump body limiting structure can also ensure that the pump body 1000 is smoothly transported from the assembly station 700 to the discharge trough 600, preventing the pump body 1000 from falling during the transportation process.

[0044] The rotating mechanism 100 moves the pump body 1000 and dust cover of the assembly slot 110 to the assembly station 700, so that the assembly slot 110 is moved below the pressure head 510; the linear push rod drives the pressure head 510 to move downward, so that the pressure head 510 presses the dust cover downward, so that the dust cover is installed on the top of the pump body 1000. Before the suction pipe assembly mechanism 400 assembles the suction pipe to the bottom of the pump core 1010, it is necessary to ensure that the pressure head 510 presses the dust cover and the pump body 1000 downward to avoid the assembly head 410 of the suction pipe assembly mechanism 400 pushing the pump body 1000 upward, causing the suction pipe to be installed in place; after the suction pipe assembly mechanism 400 completes the assembly of the suction pipe, the linear push rod drives the pressure head 510 to move upward to release the dust cover and the pump body 1000, so that the rotating mechanism 100 can move the pump body 1000 in the assembly slot 110 to the lower material trough 600.

[0045] Reference Figure 3 As shown, the feeding trough 600 is connected to the frame 10. The feeding trough 600 is located on the periphery of the rotating mechanism 100 and is located below the rotating mechanism 100.

[0046] The guide plate 900 is connected to the frame 10. The guide plate 900 is located on the periphery of the rotating mechanism 100 and above the discharge trough 600. The guide plate 900 extends into the clearance groove 120 on the outer peripheral surface of the rotating mechanism 100 and extends from the clearance groove 120 to above the discharge trough 600.

[0047] When the rotating mechanism 100 moves the pump body 1000 in the assembly slot 110 to the guide plate 900, the guide plate 900 abuts against the outer wall of the pump body 1000, guiding the pump body 1000 to the top of the discharge slot 600. The guide plate 900 pushes the pump body 1000 out of the assembly slot 110, causing the pump body 1000 to fall into the discharge slot 600.

[0048] The assembled pump body 1000 is transported via the pump body conveying channel 200 to the assembly channel 110 of the rotating mechanism 100. Then, the dust cover conveying channel 300 transports the dust cover to the assembly channel 110 and it falls on top of the pump body 1000. After that, the assembly channel 110 moves to the assembly station 700. The dust cover pressing mechanism 500, located above the assembly station 700, presses the dust cover down to assemble it onto the top of the pump body 1000, thereby fixing the position of the dust cover and the pump body. The suction pipe assembly mechanism 400 inserts the suction pipe upward into the fixed bottom of the pump body 1000. Thus, the dust cover and suction pipe are assembled onto the pump body 1000 at the same position in the assembly station 700. This simplifies the assembly process, optimizes the assembly flow of the manual pump, and helps to improve the assembly efficiency of the manual pump.
