It has a wide range of applications. A miniature air pump typically includes a motor, an eccentric structure, an air bladder, and a housing assembly.

[0057] A miniature air pump is a small, gaseous gas delivery device used for various purposes such as gas sampling, gas circulation, vacuum adsorption, vacuum pressure holding, evacuation, and air inflation. It has a wide range of applications. A miniature air pump typically includes a motor, an eccentric structure, an air bladder, and a housing assembly. When the motor is in operation, the eccentric structure pulls the end of the air bladder up and down, thus stretching or compressing the air bladder to complete the intake and exhaust processes. The assembly process of the air pump is relatively complicated, involving the assembly of multiple components. The assembly process requires manual assistance, resulting in insufficient automation and low assembly efficiency.

[0058] This invention proposes an air pump assembly device.

[0059] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the air pump assembly equipment includes:

[0060] Conveying mechanism 100;

[0061] Tower assembly mechanism 200, tower assembly mechanism 200 is used to assemble tower component 210;

[0062] Umbrella assembly mechanism 300, which is used to assemble umbrella assembly 310;

[0063] Motor assembly mechanism 400, used for assembling motor assemblies; and

[0064] The complete machine assembly mechanism 500 assembles the tower-shaped component 210, the umbrella-shaped component 310 and the motor component to generate an air pump;

[0065] The conveying mechanism 100 extends along the tower assembly mechanism 200, the umbrella assembly mechanism 300, the motor assembly mechanism 400, and the complete machine assembly mechanism 500 to transport the assembled tower component 210, umbrella component 310, and motor component to the complete machine assembly mechanism 500 respectively.

[0066] In the technical solution of the present invention, the air pump includes a tower-shaped component 210, an umbrella-shaped component 310 and a motor component arranged sequentially. Since the conveying mechanism 100 extends along the tower-shaped assembly mechanism 200, the umbrella-shaped assembly mechanism 300 and the motor assembly mechanism 400, each component after assembly can be transported by the conveying mechanism 100. The conveying mechanism 100 transports the assembled tower-shaped component 210, the umbrella-shaped component 310 and the motor component to the complete machine assembly mechanism 500, and assembles them into an air pump at the complete machine assembly mechanism 500. The assembled air pump is transported by the conveying mechanism 100 and transferred away from the complete machine assembly mechanism 500 to complete the assembly of the air pump. The entire process does not require manual intervention, and the automation level of the equipment processing is high, which also improves the assembly efficiency of the air pump.

[0067] In a specific embodiment, two tower-shaped assembly mechanisms 200, two umbrella-shaped assembly mechanisms 300, and two motor assembly mechanisms 400 can be provided for simultaneous processing to improve processing efficiency. The two tower-shaped assembly mechanisms 200 can be located on opposite sides of the conveying mechanism 100. After the tower-shaped component 210 is processed, it is placed on the conveying mechanism 100, and the conveying mechanism 100 continues to move towards the complete machine assembly mechanism 500. The two umbrella-shaped assembly mechanisms 300 are located on one side of the conveying mechanism 100, and the two motor assembly mechanisms 400 are located on the other side of the conveying mechanism 100. The umbrella-shaped assembly mechanism 300 and the motor assembly mechanism 400 are arranged opposite each other on both sides of the conveying mechanism 100. The motor assembly and umbrella-shaped assembly 310 and other components generated by the assembly are placed on the conveying mechanism 100. The conveying mechanism 100 transports them together to the complete machine assembly mechanism 500. The complete machine assembly mechanism 500 assembles the three components, umbrella-shaped assembly 310, tower-shaped assembly 210 and motor assembly, into an air pump. The other two umbrella-shaped assemblies 310 can be arranged on both sides of the conveying mechanism 100, and the two motor assemblies can also be arranged on both sides of the conveying mechanism 100.

[0068] In addition, the assembly mechanism 500 includes a first assembly structure 510, a second assembly structure 520, and a final assembly assembly. The first assembly structure 510 and the second assembly structure 520 are sequentially arranged on one side of the conveying mechanism 100. The first assembly structure 510 is used to assemble the tower-shaped assembly 210 and the umbrella-shaped assembly 310, and to install the tower-shaped assembly 210 on top of the umbrella-shaped assembly 310. The second assembly structure 520 is used to install the tower-shaped assembly 210 on top of the motor assembly. Screws are provided at the second assembly structure 520 to screw the umbrella-shaped assembly 310, the tower-shaped assembly 210, and the motor assembly together.

[0069] In the embodiments of the present invention, please refer to Figure 4 The tower-shaped component 210 includes an airbag 211, a fixed base 212, and a connecting rod 213. The tower-shaped assembly mechanism 200 includes a first frame 220, a first turntable 230, an airbag feeding device 240 for providing the airbag 211, a fixed base feeding device 250 for providing the fixed base 212 and fitting the fixed base 212 onto the airbag 211, a connecting rod feeding device 260 for providing the connecting rod 213 and mounting the connecting rod 213 onto the airbag 211, and a first... The unloading device 270, and the airbag loading device 240, the fixed seat loading device 250, the connecting rod loading device 260 and the first unloading device 270 are arranged sequentially and at intervals along the circumference of the first turntable 230. The first turntable 230 is provided with a processing station. The first turntable 230 is rotatably mounted on the first frame 220, so that the processing station passes through the airbag loading device 240, the fixed seat loading device 250, the connecting rod loading device 260 and the first unloading device 270 in sequence.

[0070] Specifically, please refer to Figure 3On the first frame 220, a first turntable 230 is mounted on the first frame 220 via a motor. The processing station rotates with the turntable, causing it to pass sequentially through an airbag loading device 240, a fixed base loading device 250, a connecting rod loading device 260, and a first unloading device 270. The airbag loading device 240 includes a vibrating loading bin containing several airbags 211 and a negative pressure adsorption component. The negative pressure adsorption component is driven by a motor and cylinder to move in multiple directions, causing it to adsorb an airbag 211 at the vibrating loading bin and place it at the processing station. Because the airbag 211 is made of a relatively soft material, transferring it to the processing station via the negative pressure adsorption component can prevent deformation of the airbag 211. As the first turntable 230 rotates, the processing station moves with the first turntable 230. The rotation of the turntable causes the processing station to rotate to the corresponding fixed seat loading device 250. The fixed seat loading device 250 includes a vibrating loading tank containing several fixed seats 212 and a first mechanical gripper. The first mechanical gripper is driven by multiple drive structures to move along a first direction, a second direction, and a third direction, with each of the three directions being perpendicular to the others. After the first mechanical gripper picks up the fixed seat 212, it places the fixed seat 212 on the processing station, so that the fixed seat 212 is fitted around the outer periphery of the airbag 211. Since the air vent of the airbag 211 is a pointed tip, and the fixed seat 212 has multiple insertion holes in the middle, when the fixed seat 212 is placed on the airbag 211, the pointed tip passes through the insertion holes and protrudes from the insertion holes. At this time, the processing station rotates with the turntable. The device moves to the corresponding connecting rod feeding device 260. The connecting rod feeding device 260 includes a vibrating feeding hopper containing several connecting rods 213 and a second mechanical gripper. The second mechanical gripper moves in multiple directions via multiple driving components. Each direction is different and perpendicular to the others. A motor drives the second mechanical gripper to rotate, adjusting the direction and angle of the connecting rods 213 for easy assembly. The second mechanical gripper removes the connecting rods 213 from the vibrating feeding hopper and places them on the processing station. Multiple insertion holes are provided circumferentially on the connecting rods 213, and a shaft is positioned at the center of these holes, i.e., the axis of the connecting rod 213. Multiple tips are inserted into each insertion hole and protrude beyond it, i.e., the tips of the airbags 211... The tower-shaped component 210 is assembled by passing through the fixed base 212 and connecting rod 213. The tower-shaped component 210 moves to the corresponding first unloading device 270 at the processing station as the first turntable 230 rotates. The first unloading device 270 includes a third mechanical gripper and a drive structure. The drive structure drives the third mechanical gripper to grasp the assembled tower-shaped component 210 and move it horizontally and vertically, thus moving the tower-shaped component 210. A rotating component is set at the first frame 220. The rotating component grasps the tower-shaped component 210 held by the third mechanical gripper and rotates it 180° up and down to adjust the orientation of the tower-shaped component 210 so that the airbag 211 rotates upwards and the connecting rod 213 rotates downwards, facilitating subsequent assembly of the tower-shaped component 210 with other components.Specifically, the connecting rod 213 has its shaft side facing downwards for easy assembly with the subsequent motor assembly, and the airbag 211 has its side away from the tip facing upwards for easy assembly with the umbrella-shaped assembly 310. The third robotic gripper moves the rotated tower-shaped assembly 210 to the buffer platform, facilitating the transfer of the tower-shaped assembly 210 from the buffer platform to the conveying mechanism 100 by the fourth robotic gripper.

[0071] In addition, multiple processing stations are arranged circumferentially on the first turntable 230, and the angle between each processing station is the same as the angle between the adjacent devices mentioned above, which facilitates the simultaneous assembly of the tower-shaped component 210 at each processing station and improves the processing efficiency of the tower-shaped component 210.

[0072] In an embodiment of the present invention, the tower-shaped assembly mechanism 200 further includes a stretching device 280 and a shearing device 290, which are located between the connecting rod feeding device 260 and the first unloading device 270.

[0073] Specifically, refer to Figure 3 The processing station moves to the corresponding stretching device 280 as the first turntable 230 rotates. The stretching device 280 includes a first pressure plate and multiple first grippers. The first pressure plate has multiple through holes, and each tip is inserted into a corresponding through hole with its tip pointing upwards. That is, the first pressure plate is used to press the connecting rod 213 downwards. Each first gripper grips a tip above the first pressure plate and pulls the tip upwards by suction, so that the connecting rod 213 is limited to the tip, which improves the stability of the assembly of the airbag 211, the fixing seat 212 and the connecting rod 213. In addition, when the processing station rotates to the corresponding shearing device 290, the shearing device 290 includes scissors and a drive structure. The drive structure drives the scissors to cut the part of the connecting rod 213 with its tip protruding, so as to facilitate subsequent assembly.

[0074] In an embodiment of the present invention, the umbrella-shaped assembly 310 includes a partition, an umbrella valve, and a valve cover; the umbrella-shaped assembly mechanism 300 includes a second frame 320, a second turntable 330, a partition loading device 340 for providing the partition, an umbrella valve loading device 350 for providing the umbrella valve and assembling the umbrella valve on the partition, a valve cover loading device 360 ​​for providing the valve cover and assembling the valve cover with the partition, and a second unloading device 370. The partition loading device 340, the umbrella valve loading device 350, the valve cover loading device 360, and the second unloading device 370 are arranged sequentially and spaced apart along the circumference of the second turntable 330. The second turntable 330 is provided with an assembly station, and the second turntable 330 is rotatably mounted on the second frame 320, such that the assembly station passes sequentially through the partition loading device 340, the umbrella valve loading device 350, the valve cover loading device 360, and the second unloading device 370.

[0075] Specifically, please refer to Figure 6The umbrella-shaped component 310 includes a valve cover and a partition arranged sequentially. The umbrella valve is inserted into the partition. The side of the partition away from the valve cover is used for assembly with the airbag 211 of the tower-shaped component 210. Specifically, a second turntable 330 is rotatably arranged on the second frame 320, with the same structure as the first frame 220 and the first turntable 230, which will not be described in detail here. An assembly station is set on the second turntable 330, so that the assembly station passes sequentially through the partition loading device 340, the umbrella valve loading device 350, and the valve cover loading device 360 ​​as the second turntable 330 rotates. The partition loading device 340 includes a first vibrating plate holding several partitions and a first robotic arm. The first vibrating plate is located on the second frame 320. The first robotic arm grabs a partition and places it on the assembly station. The assembly station rotates with the second turntable 330 to the corresponding umbrella valve loading device 350. 0. Since each umbrella valve has multiple valve holes spaced apart circumferentially to allow the umbrella valve to be inserted into the valve holes, the umbrella valve feeding device 350 includes a storage plate and a first adsorption structure. The storage plate is located on the second frame 320, and multiple umbrella valves are placed on the storage plate. The first adsorption structure adsorbs the umbrella valves and moves towards the second turntable 330. The first adsorption structure places the umbrella valves into each valve hole. The assembly station rotates to the corresponding valve cover feeding device 360. The valve cover feeding device 360 ​​includes a second vibrating plate and a second adsorption structure. The second vibrating plate contains several valve covers. The second adsorption structure adsorbs the valve covers and places them on the assembly station. The needle tip of the valve cover passes downward through the assembly station and the second turntable 330. After the umbrella component 310 is assembled, it is transferred to the conveying mechanism 100 by the second unloading device 370.

[0076] In this embodiment, the second unloading device 370 is similar in structure to the first unloading device 270, including a third robotic arm, a buffer platform, and a rotating gripper. The third robotic arm is controlled by two cylinders to move in the horizontal and vertical directions. After the third robotic arm picks up the umbrella-shaped component 310, it places it on the rotating gripper. The rotating gripper is driven to rotate by a rotary cylinder, which drives the rotating gripper to rotate 180°, so that the umbrella-shaped component 310 consists of a valve cover and a partition from top to bottom. The valve cover has a needle tip facing upward, and the partition has the side away from the valve cover facing downward, which facilitates subsequent assembly with the tower-shaped component 210. After being rotated, the umbrella-shaped component 310 is picked up and placed on the buffer platform by the third robotic arm. The buffer platform is a rotary cylinder. According to the subsequent installation angle of the umbrella-shaped component 310, the buffer platform adjusts the angle of the umbrella-shaped component 310 in the horizontal direction. After the adjustment is completed, the fourth robotic arm transfers the umbrella-shaped component 310 to the conveying mechanism 100.

[0077] The umbrella-shaped assembly mechanism 300 also includes an assembly device, which is set between the valve cover feeding device 360 ​​and the second unloading device 370. The assembly device includes a second robot arm, which moves horizontally and vertically through two cylinders. When the assembly station moves to the corresponding assembly device, the second robot arm grabs the partition and places it on the valve cover, so that the threaded hole of the valve cover corresponds to the threaded hole of the partition. At this time, the needle tip of the valve cover is facing down. Before unloading, it is rotated 180° by a rotating cylinder.

[0078] Additionally, a material-picking device is provided at the bottom of the valve cover feeding device 360 ​​corresponding to the position of the second turntable 330. The material-picking device includes a picking component, a slide rail, and a collection bin. The picking component is installed on the second frame 320 and uses a cylinder gripper to pick up the needle cap on the valve cover. The needle cap is fastened to the needle tip. When the cylinder gripper is released, the needle cap falls onto the slide rail, which is connected to the collection bin. The collection bin collects the needle caps on the valve cover for subsequent reuse.

[0079] It should also be noted that multiple assembly stations are set on the second turntable 330, and these multiple assembly stations are spaced apart along the circumference of the second turntable 330, so that different assembly stations can perform different assembly processes for different devices, thereby improving the assembly efficiency of the umbrella-shaped component 310.

[0080] In an embodiment of the present invention, the umbrella valve includes an umbrella cap and an umbrella handle, and the partition is provided with a socket through which the umbrella handle passes;

[0081] The umbrella assembly mechanism 300 also includes a tensioning device 380 and a cutting device 390. The tensioning device 380 and the cutting device 390 are located between the umbrella valve feeding device 350 and the valve cover feeding device 360. The tensioning device 380 is used to pull the umbrella handle so that the umbrella cap is engaged at the insertion hole. The cutting device 390 is used to cut the part of the umbrella handle that protrudes from the insertion hole.

[0082] Specifically, please refer to Figure 6After the first adsorption structure places the umbrella valve into the insertion hole of the partition, the umbrella handle protrudes downward from the insertion hole. A tensioning device 280 is set below the second turntable 330. The tensioning device 280 pulls the umbrella handle downward, so that the umbrella cap is locked into the insertion hole, thereby making the umbrella valve and the partition more closely assembled. Then, by rotating the second turntable 330, the assembly station is aligned with the cutting device 390. The cutting device 390 cuts off the umbrella handle protruding from the partition, improving the stability of the connection between the umbrella valve and the partition. The tensioning device 280 includes a second pressure plate located above the second turntable 330 and a second gripper located below the second turntable 330. The second pressure plate presses the partition on the second turntable 330, and the second gripper moves downward below the second turntable 330 driven by a cylinder to pull the umbrella handle. The cutting device 390 has a similar structure to the shearing device 290. It also consists of several scissors driven by a cylinder to cut off the part of the umbrella handle protruding from the insertion hole, which facilitates a more stable assembly of the umbrella valve and the partition.

[0083] In an embodiment of the present invention, the motor assembly includes a motor, a base housing, and an eccentric body;

[0084] The motor assembly mechanism 400 includes a third frame 410, a third turntable 420, a motor feeding device 430 for providing the motor, a bottom shell feeding device 440 for providing the bottom shell and mounting the bottom shell on the motor, an eccentric feeding device 450 for providing the eccentric body and mounting the eccentric body on the bottom shell, and a third unloading device 460. The motor feeding device 430, the bottom shell feeding device 440, the eccentric feeding device 450, and the third unloading device 460 are arranged sequentially and spaced apart along the circumference of the third turntable 420. The third turntable 420 is provided with an assembly station, and the third turntable 420 is rotatably mounted on the third frame 410, so that the assembly station passes through the motor feeding device 430, the bottom shell feeding device 440, the eccentric feeding device 450, and the third unloading device 460 in sequence.

[0085] Specifically, please refer to Figure 7The third turntable 420 is mounted on the third frame 410 via a motor. The assembly station on the third turntable 420 passes sequentially through the motor feeding device 430, the bottom shell feeding device 440, and the eccentric feeding device 450. Multiple buffer plates are mounted on the third frame 410, each holding multiple motors. The motor feeding device 430 sequentially transports the motors from the buffer plates to the assembly station, and then moves them with the rotation of the third turntable 420 to the bottom shell feeding device 440. The bottom shell feeding device 440 delivers the bottom shell to the assembly station and places it on the motor... As the third turntable 420 rotates, the assembly station rotates to the eccentric feeding device 450, which is used to place the eccentric body on the bottom shell. In addition, a steel ball feeding device 470 is also provided to place steel balls on the eccentric body. A liquid sealing device 480 is provided to liquid seal the steel balls and the eccentric body to improve the sealing effect and prevent the steel balls from rusting after long-term use. Then, the motor assembly is transferred to the conveying mechanism 100 by the third unloading device 460. The third unloading device 460 can adopt the same structure as the first unloading device 270 and the second unloading device 370.

[0086] The bottom shell feeding device 440 includes a first feeder and a first clamp. The first feeder contains several bottom shells. The first clamp moves horizontally and vertically through a first driving device. The first driving device drives the first clamp to move so that the first clamp can grip the bottom shell on the first feeder and place it at the assembly station. The first driving device can be a cylinder, hydraulic cylinder, or electric telescopic rod to move the first clamp. The eccentric feeding device 450 includes a second feeder and a second clamp. The second clamp moves horizontally and vertically through a second driving device. The second driving device drives the second clamp to grip the eccentric body in the second feeder and move it toward the third turntable 420 to place the eccentric body on the bottom shell.

[0087] Furthermore, the steel ball feeding device 470 includes a container for storing steel balls and a pusher. When the assembly station rotates to the corresponding steel ball feeding device 470, the steel balls in the container fall into the slide. The pusher picks up a steel ball on the slide and moves downward through a structure such as a cylinder to place the steel ball in the mounting hole of the eccentric body, which facilitates the reduction of friction during the operation of the subsequent motor assembly. The liquid sealing device 480 includes an oiler. The oiler moves downward through a structure such as a cylinder and injects oil at the steel ball.

[0088] Once the motor assembly is manufactured, it is transported to the final assembly unit 500. Please refer to [reference needed]. Figure 8 , Figure 9 and Figure 10The first assembly structure 510 includes a base 511. A suction component 512 and a positioning component are installed below the base 511. The suction component 512 is used to suction the umbrella-shaped component 310, and the positioning component is used to position the tower-shaped component 210. The tower-shaped component 210 and the umbrella-shaped component 310 are assembled through the cooperation of the suction component 512 and the positioning component. On the conveying mechanism 100, the partition of the umbrella-shaped component 310 faces downwards, and one end of the needle tip faces upwards. In the tower-shaped component 210, the end of the airbag 211 facing away from the connecting rod 213 faces upwards, while the connecting rod 213 faces downwards. The end of the airbag 211 facing away from the connecting rod 213 is provided with a protrusion, which includes multiple circumferentially... The partition plate has fins 2111 spaced apart, and a limiting hole is provided at the axial center of the partition plate. The peripheral wall of the limiting hole has multiple limiting grooves that are adapted to the fins 2111. The suction assembly 512 uses a pneumatic suction device to suction the umbrella-shaped assembly 310. The positioning assembly includes a rotary cylinder 513, a guide plate 514, a sliding column 515, and a spring plate 516. The rotary cylinder 513 drives the guide plate 514 to rotate. The guide plate 514 has multiple arc-shaped grooves 5141 spaced apart along its circumference. The two ends of the arc-shaped grooves 5141 are close to and far from the axis of the guide plate 514, respectively, and are staggered in the radial direction. The number of arc-shaped grooves 5141 corresponds to the fins 2111 and the... The limiting grooves are arranged such that a sliding column 515 is slidably installed in each arc-shaped groove 5141. The sliding column 515 is connected to a spring piece 516 through a bracket. That is, when the rotary cylinder 513 drives the guide disk 514 to rotate, the rotation of the arc-shaped groove 5141 causes the sliding column 515 to slide within the arc-shaped groove 5141, so that the sliding column 515 moves radially along the guide disk 514, and then drives the spring piece 516 to move radially. The axis of the guide disk 514 corresponds to the pneumatic adsorption device, that is, the umbrella-shaped component 310 is located directly below the axis of the guide disk 514. During specific assembly, the suction component 512 first adsorbs the umbrella-shaped component 310, and then the suction component 516 is drawn into the air. The material assembly 512 and the positioning assembly are moved to the top of the tower assembly 210 via a screw module or cylinder. The spring piece 516 moves radially inward and drives the tower assembly 210 to move directly below the umbrella assembly 310. The end of the spring piece 516 facing the axis abuts against the fin 2111, causing the fin 2111 to retract inward and the protrusion to insert into the limiting hole and cooperate with the limiting groove. At this time, with the reverse rotation of the guide plate 514, the sliding column 515 moves radially outward, the spring piece 516 releases the fin 2111, the fin 2111 expands outward and is limited by the limiting groove, and then the tower assembly 210 and the umbrella assembly 310 are assembled.

[0089] Also, please refer to Figure 11The second assembly structure 520 includes a robotic arm 521. The output end of the robotic arm 521 grips the assembled umbrella-shaped component 310 and tower-shaped component 210 and places them on the motor assembly. It should be noted that one end of the connecting rod 213 of the tower-shaped component 210 is facing downwards, and the shaft is inserted into the eccentric body of the motor assembly. The shaft engages with the steel ball in the eccentric body. Thus, the structure of the air pump from top to bottom consists of the umbrella-shaped component 310, the tower-shaped component 210, and the motor assembly, and the three are connected by screws.

[0090] In an embodiment of the present invention, the air pump assembly equipment further includes a tray 150 for placing the assembled components, and the conveying mechanism 100 includes:

[0091] Frame 110;

[0092] The first conveyor line 120 is provided on the frame 110 for conveying the pallet 150 and the components placed on the pallet 150;

[0093] The second conveyor line 130 is located on the frame 110 and below the first conveyor line 120. The transport direction of the second conveyor line 130 is opposite to that of the first conveyor line 120, and it is used to transport the pallet 150.

[0094] The first conveyor line 120 and the second conveyor line 130 both extend along the tower-type assembly mechanism 200, the umbrella-type assembly mechanism 300, the motor assembly mechanism 400, and the complete machine assembly mechanism 500.

[0095] Specifically, please refer to Figure 12 The conveying mechanism 100 includes a first conveyor line 120 and a second conveyor line 130, which are arranged sequentially from top to bottom on the frame 110. The first conveyor line 120 and the second conveyor line 130 extend in the same direction but transport in opposite directions. A tray 150 is provided on the first conveyor line 120 to carry the tower-shaped assembly 210, the umbrella-shaped assembly 310, and the motor assembly, and to transport the tray 150 to the assembly mechanism 500. After the air pump is assembled, it continues to move on the tray 150. The air pump is removed at the end of the first conveyor line 120, while the empty pallet 150 is placed at the beginning of the second conveyor line 130 for recycling. The empty pallet 150 is transported towards the end of the second conveyor line 130 as the second conveyor line 130 operates. The beginning of the first conveyor line 120 is above the end of the second conveyor line 130. When the empty pallet 150 is transported to the end of the second conveyor line 130, it is moved to the beginning of the first conveyor line 120, and the components are moved again.

[0096] In an embodiment of the present invention, a transfer component 140 is provided at each end of the frame 110. One of the two transfer components 140 is used to transfer the pallet 150 on the first conveyor line 120 to the second conveyor line 130, and the other of the two transfer components 140 is used to transfer the pallet 150 on the second conveyor line 130 to the first conveyor line 120.

[0097] Specifically, please refer to Figure 13 The transfer assembly 140 is located at both ends of the frame 110 and is used to move the pallet 150 between the first conveyor line 120 and the second conveyor line 130. Specifically, the transfer assembly 140 includes a lifting drive 141 and a support 142. The lifting drive 141 can use a cylinder, hydraulic cylinder, electric telescopic rod or screw module to drive the support 142 to move. The lifting drive 141 is set vertically, thereby driving the support 142 to move vertically, which facilitates the transfer between the first conveyor line 120 and the second conveyor line 130.

[0098] In another embodiment, the support member 142 adopts a transmission structure, which includes two parallel conveyor belts 143. The extension direction of the conveyor belts 143 is the same as the extension direction of the first conveyor line 120. Rollers are provided at both ends of the two conveyor belts 143, and a rotating shaft is provided between the two rollers at one end of the two conveyor belts 143. The rotating shaft is connected to a motor via a belt. The motor drives the rotating shaft to rotate, which in turn drives the two conveyor belts 143 to rotate. It should be noted that the transmission structure is driven by the lifting drive member 141. When the transmission structure moves to the same height as the first conveyor line 120, the conveying direction of the conveyor belts 143 is the same as the direction of the first conveyor line 120. When the transmission structure moves to the same height as the second conveyor line 130, the conveying direction of the conveyor belts 143 is the same as the direction of the second conveyor line 130. Taking the transfer component 140 at the tail end of the first conveyor line 120 as an example... The first conveyor line 120 transports pallet 150 to its tail end. As the first conveyor line 120 rotates, pallet 150 approaches the transmission structure. When the edge of pallet 150 contacts conveyor belt 143, the empty pallet 150 is transferred from the first conveyor line 120 to conveyor belt 143 as conveyor belt 143 rotates. That is, the two sides of the bottom of pallet 150 contact the two conveyor belts 143. At this time, the lifting drive 141 drives the transmission structure to descend. When conveyor belt 143 is at the same height as the second conveyor line 130, the conveying direction of conveyor belt 143 is adjusted to be the same as the operating direction of the second conveyor line 130 so that the empty pallet 150 can be transferred to the second conveyor line 130. It can be understood that the first end of the first conveyor line 120, which is also the tail end of the second conveyor line 130, is set up as described above to facilitate the transfer of pallet 150. Moreover, the entire handling process does not require human intervention, realizing the recycling of pallet 150.

[0099] In an embodiment of the present invention, the air pump assembly equipment further includes a testing mechanism 600, which includes:

[0100] Fourth rack 610;

[0101] The fourth turntable 620 is rotatably mounted on the fourth frame 610, and a support plate 630 is provided on the fourth turntable 620;

[0102] The gripping component 640 is located on the fourth frame 610. The gripping component 640 transfers the air pump on the conveying mechanism 100 to the support plate 630 so that the pins of the motor assembly face down and pass through the support plate 630.

[0103] The measuring device 650 is located on the fourth frame 610 and is used to connect the pins.

[0104] Specifically, please refer to Figure 14 The fourth turntable 620 is mounted on the fourth frame 610 via a motor. Multiple support plates 630 are spaced apart on the fourth turntable 620. The gripping component 640 places the air pump on the support plate 630. The support plate 630 has multiple through holes, and the air pump is placed at the corresponding through hole with the motor assembly pins facing down and passing through the through hole. The umbrella-shaped component 310 is above the support plate 630. The electrical testing device 650 is set on the fourth frame 610. After the support plate 630 carries the air pump, it rotates with the fourth turntable 620 to the corresponding electrical testing device 650. The electrical testing device 650 includes a support plate located below the fourth turntable 620. Multiple electrical connectors are provided above the support plate, and a cylinder or similar structure is installed below the support plate to drive the support plate to rise and fall. When the support plate rises, the electrical connectors contact the pins below the motor assembly to perform a conductivity test on the air pump and detect whether the motor assembly can operate normally.

[0105] In an embodiment of the present invention, the testing mechanism 600 further includes a ventilation device 660, which includes a plug and an airtightness meter, and the plug and the airtightness meter are respectively connected to an air pump.

[0106] Specifically, a first mounting base and a second mounting base are provided on the fourth frame 610. The first mounting base is positioned corresponding to the measuring device 650 and is moved radially along the fourth turntable 620 by a cylinder. An air tightness tester is installed on the first mounting base, and the air tightness tester is connected to the air inlet of the air pump. Since the air outlet is not blocked, the air tightness tester can monitor the internal air pressure of the air pump to perform air tightness testing on the air pump. A blocking component is provided on the second mounting base. By moving the second mounting base radially along the fourth turntable 620, the blocking component blocks the air inlet of the air tightness tester. The air tightness tester is located above the second mounting base and is used to connect to the air outlet of the air pump to test the air tightness of the air pump. In addition, a positioning gripper is provided on the support plate 630 below the second mounting base. The positioning gripper is driven to rise and fall by a cylinder and other structures. The positioning gripper is used to grip the motor assembly to fix the air pump during air tightness testing, thereby improving measurement efficiency and yield.
