[0049] The present application provides an assembling device for a dust collector bottom cover of a dust collector.

[0050] Please refer to Figures 1 to 6In an embodiment of the present application, the dust collector bottom cover assembling device is used for assembling the bottom cover 25 of the dust collector, the bottom cover 25 comprises a cover body 251 and a sealing ring 252, the cover body 251 is provided with a through hole 2511 and a first boss 2512 arranged around the outer periphery of the through hole 2511, and the sealing ring 252 is used for sleeving the outer peripheral wall of the first boss 2512, the sealing ring 252 comprises an arc segment 2521 and a straight line segment 2522, the outer peripheral surface of the first boss 2512 comprises a straight surface segment 25121 and an arc surface segment 25122, the outer periphery of the cover body 251 is provided with an elastic buckle 2514, and the dust collector bottom cover assembling device comprises a base 10, a first rotating disc 11a, a cover body feeding module 14, a sealing ring feeding module 15 and a plurality of bearing tables 12, the base 10 is provided with a first feeding station 101 and a second feeding station 102 located downstream of the first feeding station 101; the first rotating disc 11a is rotatably arranged on the base 10 and can rotate between the first feeding station 101 and the second feeding station 102; the upper surface of the bearing table 12 is provided with a plurality of first positioning columns 121 and two second positioning columns 122, the two second positioning columns 122 are arranged at intervals along the edge of the bearing table 12 and are formed with a positioning gap 123 for clamping the elastic buckle 2514, and a plurality of first positioning columns 121 are arranged at intervals along the circumferential direction of the bearing table 12 and are used for abutting against the hole wall surface of the through hole 2511 and / or the outer peripheral wall of the cover body 251; the plurality of bearing tables 12 comprise a first bearing table 12a arranged on the first rotating disc 11a; the cover body feeding module 14 is arranged on the base 10 and is used for placing the cover body 251 on the first bearing table 12a located at the first feeding station 101; and the sealing ring feeding module 15 is arranged on the base 10 and is used for placing the sealing ring 252 on the cover body 251 of the first bearing table 12a located at the second feeding station 102, and the straight line segment 2522 is arranged on the side away from the second positioning column 122 of the central axis of the bearing table 12, so that the straight line segment 2522 can be aligned with the straight surface segment 25121.

[0051] The sealing performance of the dust collector bottom cover 25 directly affects the suction efficiency and dust prevention effect of the whole machine during the operation of the dust collector. The bottom cover 25 of the application comprises a cover body 251 and a sealing ring 252 sleeved thereon. Among them, the cover body 251 is provided with a through hole 2511 for connecting the internal airflow channel of the dust collector. A first boss 2512 is formed on the outer periphery of the through hole 2511 for bearing the sealing ring 252. The outer peripheral surface of the first boss 2512 comprises a straight surface section 25121 and an arc surface section 25122 matched with the shape of the sealing ring 252, for providing accurate positioning support surface. The sealing ring 252 comprises an arc section 2521 and a straight line section 2522 connecting both ends of the arc section, and the sealing ring 252 is in the shape of D. The sealing ring 252 needs to be accurately sleeved on the outer peripheral wall of the first boss 2512, so that the arc section of the sealing ring 252 corresponds to abut against the arc surface section 25122 of the first boss 2512, and the straight line section 2522 corresponds to abut against the straight surface section 25121 of the first boss 2512, to ensure that it can form uniform and reliable sealing with the inner wall of the dust collecting box in subsequent use. In addition, the outer periphery of the cover body 251 is also provided with an elastic buckle 2514 for quick locking and dismounting when installed to the dust collector. However, due to the irregular geometric shape of the sealing ring 252, it is difficult to ensure the accuracy of its direction and position during assembly by manual or ordinary automatic equipment, which may cause the straight line section 2522 to fail to align with the straight surface section 25121 on the cover body 251, thereby causing poor sealing, assembly out of position and other problems.

[0052] Therefore, the application provides an assembly equipment for the dust collector bottom cover of a dust collector. The assembly equipment comprises a base 10, a first rotating disc 11a rotatably arranged on the base 10, a cover body feeding module 14, a sealing ring feeding module 15 and a plurality of carrying tables 12. The base 10 is provided with a first feeding station 101 and a second feeding station 102 downstream thereof, and the first rotating disc 11a can rotate each carrying table 12 from the first feeding station 101 to the second feeding station 102 under the drive of the driving mechanism, realizing the orderly flow between processes. The first rotating disc 11a is provided with at least one first carrying table 12a for receiving and positioning the cover body 251 and the sealing ring 252 between the two stations.

[0053] Specifically, the upper surface of each bearing table 12 is provided with a plurality of first positioning columns 121 and two second positioning columns 122. The plurality of first positioning columns 121 are arranged along the circumference of the bearing table 12, and their positions and distributions are adapted to the through holes 2511 on the cover body 251 and / or the outer circumferential wall of the cover body 251. When the cover body 251 is placed on the bearing table 12, the first positioning columns 121 can realize accurate positioning and limiting of the cover body 251 in the horizontal direction by abutting the hole wall surface of the through holes 2511 and / or the outer circumferential wall of the cover body 251, thereby preventing the cover body 251 from deviating in subsequent operations. The two second positioning columns 122 are symmetrically or asymmetrically arranged along the edge of the bearing table 12, and a positioning gap 123 with a certain width is formed between the two second positioning columns 122. The positioning gap 123 is used to accommodate and clasp the elastic buckle 2514 on the outer circumference of the cover body 251, preventing the cover body 251 from rotating circumferentially while allowing the cover body 251 to be placed on the first bearing table 12a in a specific posture. When the cover body 251 moves from the first feeding station 101 to the second feeding station 102 with the first bearing table 12a rotating on the first turntable 11a, the straight line segment 2522 of the sealing ring 252 can be aligned with the straight surface segment 25121 of the cover body 251, and the arc line segment 2521 of the sealing ring 252 can be aligned with the arc surface segment 25122 of the cover body 251, thereby realizing the positioning and assembly of the sealing ring 252 and the cover body 251, and improving the problem of difficult alignment of the sealing ring 252, and the out-of-position caused by deviation and distortion.

[0054] It can be understood that in the first feeding station 101, the cap body feeding module 14 places the cap body 251 to be assembled on the first carrier 12a located in the first feeding station 101. At this time, the plurality of first positioning columns 121 are inserted into the through hole 2511 and abut the hole wall surface of the through hole 2511; or abut the outer peripheral wall of the cap body 251; or part of the first positioning columns 121 abut the hole wall surface of the through hole 2511, and part of the first positioning columns 121 abut the outer peripheral wall of the cap body 251. At the same time, the elastic buckle 2514 is embedded in the positioning gap 123 between the two second positioning columns 122, realizing the all-around accurate positioning and fixing of the cap body 251. Subsequently, the first turntable 11a rotates to move the first carrier 12a on which the cap body 251 has been placed to the second feeding station 102. In the second feeding station 102, the sealing ring feeding module 15 is started to accurately place the pre-arranged sealing ring 252 on the outer periphery of the first boss 2512 on the positioned cap body 251. In the process of placing the sealing ring 252, the sealing ring 252 is controlled to have the straight line segment 2522 away from the second positioning column 122 on the side of the central axis of the carrier 12. Since the overall layout of the carrier 12 has a directional reference datum, this design ensures that the straight line segment 2522 of the sealing ring 252 can be naturally aligned with the straight surface segment 25121 on the first boss 2512 of the cap body 251, thereby realizing the double guidance of shape matching and spatial positioning, and effectively avoiding assembly failure caused by direction error or rotation deviation.

[0055] For example, in an embodiment, after the cap body 251 is placed on the first carrier 12a located in the first feeding station 101, the extension line of the connecting line of the elastic buckle 2514 and the center of the cap body 251 passes through the center of the first turntable 11a, and the extension line is perpendicular to the straight surface segment 25121 of the first boss 2512. Subsequently, the first turntable 11a rotates to move the first carrier 12a on which the cap body 251 has been placed to the second feeding station 102. At this time, the extension line of the line segment of the sealing ring 252 grabbed by the sealing ring feeding module 15 passing through the center of the arc segment thereof and being perpendicular to the straight line segment 2522 thereof passes through the center of the first turntable 11a, and the straight line segment 2522 of the sealing ring 252 is located on the side of the central axis of the carrier 12 away from the second positioning column 122, so that the straight line segment 2522 of the sealing ring 252 can be aligned with the straight surface segment 25121 of the first boss 2512, and the arc segment 2521 can be aligned with the arc surface segment 25122 of the first boss 2512, to realize the shape matching and accurate abutment of the sealing ring 252 and the cap body 251.

[0056] The technical scheme of the present application realizes multi-point and multi-degree-of-freedom accurate positioning of the cover body 251 by arranging a plurality of first positioning columns 121 on the bearing table 12, greatly improving the stability of the assembly reference; by arranging two second positioning columns 122 on the bearing table 12, the elastic buckle 2514 can be clamped in the positioning gap 123 formed thereby, limiting the circumferential rotation of the cover body 251 while allowing the cover body 251 to be placed on the first bearing table 12a in a specific attitude. The relative positional relationship between the central axis of the bearing table 12 and the second positioning column 122 is used as a directional guide to guide the assembly of the sealing ring 252 in the correct attitude, so that the straight line segment 2522 is placed on the side of the central axis of the bearing table 12 away from the second positioning column 122, so that the straight line segment 2522 of the sealing ring 252 can be aligned with the straight surface segment 25121 of the first boss 2512, and the arc segment 2521 can be aligned with the arc surface segment 25122 of the first boss 2512, thereby realizing the positioning and assembly of the sealing ring 252 and the cover body 251, and improving the difficult alignment of the sealing ring 252, and the problem of misassembly caused by deviation and distortion. In addition, the entire assembly process is driven by the first turntable 11a to realize the flow of the work station, combined with the cover body feeding module 14 and the sealing ring feeding module 15, to realize continuous, efficient and automatic assembly of the cover body 251 and the sealing ring 252, greatly improving the production efficiency and product consistency.

[0057] In an embodiment, please refer to Figure 3 、 Figure 7 and Figure 8 The cover body feeding module 14 includes a rack 141, a tray 142, a positioning detection camera 143, a moving assembly 144, and a first jaw 145 provided on the moving assembly 144. The tray 142 is used to store the cover body 251 and can move along the length direction of the rack 141. The moving assembly 144 is provided on the rack 141 and can move along the width direction and the Z-axis direction of the rack 141 relative to the rack 141. The lens of the positioning detection camera 143 faces the first feeding station 101 and can capture the second positioning column 122 located on the first feeding station 101. The first jaw 145 is used to grab the cover body 251 in the tray 142 and can rotate circumferentially.

[0058] The rack 141 is sequentially provided with a full material position, a material taking position and an empty material position in the length direction thereof. The tray 142 is movably installed on the rack 141 and can be stepwise moved along the length direction of the rack 141. The movement of the tray 142 is controlled by a driving mechanism (such as a servo motor cooperating with a lead screw or a synchronous belt). The tray 142 at the full material position can send the cap body 251 stored therein to the material taking position for being grabbed by the first gripper 145. After the cap body 251 in the tray 142 is grabbed, the tray 142 is moved to the empty material position, so as to facilitate a worker to take away the tray 142 and then put it into use after being refilled with materials. The moving assembly 144 is installed above the rack 141 and has the capability of moving along the width direction of the rack 141 and the Z-axis direction (vertical direction), which is usually realized by a multi-axis linear module or a mechanical arm structure. The moving assembly 144 can drive the first gripper 145 to be accurately positioned in space, so as to realize grabbing the cap body 251 from the tray 142 and accurately placing the cap body 251 on the first loading platform 12a of the first loading station 101.

[0059] The first gripper 145 serves as an execution end and has the functions of grabbing and releasing the cap body 251 and can be circumferentially rotated (i.e., rotated around the Z-axis). In actual assembly, the initial placement posture of the cap body 251 in the tray 142 can be inconsistent with the assembly direction on the first loading platform 12a. Through the circumferential rotation adjustment of the first gripper 145, the posture of the cap body 251 can be adjusted during the carrying process, so as to ensure that the direction of the elastic buckle 2514, the through hole 2511 and the first boss 2512 is completely matched with the positioning structure on the loading platform 12, especially the position of the elastic buckle 2514 needs to be adjusted, so that the elastic buckle 2514 can be clamped in the positioning gap 123. The lens of the positioning detection camera 143 faces the first loading station 101 and can clearly capture the two second positioning columns 122 and the placement area on the first loading platform 12a of the first loading station 101. After the first gripper 145 places the cap body 251 on the first loading platform 12a, the positioning detection camera 143 can collect and analyze images of the actual assembly position, so as to judge whether the cap body 251 is accurately positioned, especially to verify whether the elastic buckle 2514 has been correctly embedded in the positioning gap 123 and whether the through hole 2511 is aligned with the first positioning column 121. If a deviation is detected, the system can feed back a signal to the control system, so as to trigger the moving assembly 144 and the first gripper 145 to perform fine adjustment or alarm prompting, realize closed-loop control, and improve the reliability and yield of assembly.

[0060] In an embodiment, please refer to Figure 2 and Figure 8The cover body loading module 14 further comprises a reverse material detection probe 146 arranged on the moving assembly 144, and the cover body 251 is further provided with a hinged portion 2515, which is arranged on opposite sides of the central axis of the cover body 251 together with the elastic buckle 2514, and the hinged portion 2515 is arranged outside the straight surface section 25121 of the outer peripheral surface of the first boss 2512, and the hinged portion 2515 and the first boss 2512 are both arranged on the outer end surface of the cover body 251, and the reverse material detection probe 146 is arranged on the region between the two hinged portions 2515 of the outer end surface.

[0061] The outer end surface (the end surface away from the interior space of the dust collector) of the cover body 251 is provided with the first boss 2512 and the hinged portion 2515. The first boss 2512 is arranged around the through hole 2511 and used for mounting the sealing ring 252, and the hinged portion 2515 is used for movably connecting with the flip cover to enable the flip cover to open or close the through hole 2511. The hinged portion 2515 and the outer peripheral elastic buckle 2514 are arranged on opposite sides of the central axis of the cover body 251, and the hinged portion 2515 is arranged outside the straight surface section 25121 of the outer peripheral surface of the first boss 2512. The reverse material detection probe 146 is arranged on the moving assembly 144 and close to the first gripper 145. The reverse material detection probe 146 can be a mechanical or sensor contact probe and has the functions of stretching and sensing, which is used for preventing the cover body 251 from being reversely assembled and avoiding the sealing ring 252 from being unable to be mounted. When the first gripper 145 grabs the cover body 251, the end of the first gripper 145 abuts against the upper surface of the first boss 2512 (the first gripper 145 clamps the second boss 2513 on the first boss 2512). The end of the first gripper 145 and the end of the reverse material detection probe 146 have a height difference, the reverse material detection probe 146 protrudes from the first gripper 145 and abuts against the region between the two hinged portions 2515 of the outer end surface. At this time, the cover body 251 is in a “normal material” state. In this way, it can be determined whether the cover body 251 in the tray 142 is placed reversely.

[0062] It can be understood that the hinged portion 2515 and the first boss 2512 are both arranged on the outer end surface, when the cover body 251 is placed in the correct direction (i.e., the outer end surface faces upward), the region between the two hinged portions 2515 of the outer end surface of the cover body 251 will be contacted by the reverse material detection probe 146, a signal of reaching the position is triggered, and the control system judges that the cover body 251 is in a “normal material” state and allows the process to continue. Conversely, if the cover body 251 is reversely placed in the tray 142 (i.e., the outer end surface faces downward), the inner end surface will be contacted by the reverse material detection probe 146, and a specific resistance or displacement signal will be sensed during the contact. At this time, the signal fed back by the reverse material detection probe 146 will not be consistent with the standard value, the control system identifies that the cover body 251 is in a “reverse material” state, and immediately triggers an alarm or an automatic correction mechanism, for example, instructing the first gripper 145 to re-grab and adjust the direction or rejecting the defective part to prevent the error assembly from entering the subsequent process.

[0063] In an embodiment, the cap body feeding module 14 further comprises a material detection optical fiber 147 arranged on the moving assembly 144, and when the first clamping jaw 145 grabs the cap body 251, the material detection optical fiber 147 is used to detect whether the tray 142 is an empty tray 142, so that the first clamping jaw 145 can accurately and quickly take the material, and feedback the system to timely remove the empty tray 142.

[0064] In an embodiment, referring to Figures 9 to 11 , the sealing ring feeding module 15 comprises a sealing ring clamp 151, which can move along the Y-axis direction and the Z-axis direction relative to the base 10. The sealing ring clamp 151 comprises two second clamping jaws 1511 arranged at intervals, and the second clamping jaws 1511 are used to grab the connection between the arc segment 2521 and the straight segment 2522 of the sealing ring 252. The bearing table 12 is provided with a avoiding notch 124 corresponding to the straight segment 2522, and when the second clamping jaw 1511 places the sealing ring 252 on the first bearing table 12a, the second clamping jaw 1511 is located in the avoiding notch 124.

[0065] The sealing ring feeding module 15 comprises a sealing ring clamp 151, which has the movement ability along the Y-axis direction and the Z-axis direction of the base 10, and can be driven by an independent linear drive mechanism or integrated in a multi-axis robot system, so as to ensure that it can be accurately positioned to the second feeding station 102 and complete the picking and placing action of the sealing ring 252. The sealing ring clamp 151 comprises two second clamping jaws 1511 arranged at intervals, and the two second clamping jaws 1511 are used to grab the connection transition area between the arc segment 2521 and the straight segment 2522 of the sealing ring 252. The connection is usually a key point of geometric shape change, and the structure is relatively stable and the stress is uniform, which avoids the deformation, slip or torsion caused by clamping in the pure arc segment 2521 or the pure straight segment 2522. By accurately controlling the opening and closing force and clamping position of the two second clamping jaws 1511, the sealing ring clamp 151 can effectively control the spatial posture of the sealing ring 252 without damaging the sealing ring 252, especially to ensure that the straight segment 2522 of the sealing ring 252 maintains the predetermined direction during the handling process.

[0066] The bearing table 12 is provided with an avoiding gap 124 corresponding to the position of the straight segment 2522 of the sealing ring 252. The avoiding gap 124 is located at the edge region of the bearing table 12, and its position matches the final assembly posture of the sealing ring 252 in the second feeding station 102, and is consistent with the side away from the second positioning column 122. When the sealing ring clamp 151 accurately places the sealing ring 252 on the first bearing table 12a, the two second clamping jaws 1511 will simultaneously enter the avoiding gap 124 at the moment of completing the placement action. The avoiding gap 124 provides an avoiding space for the second clamping jaw 1511, avoiding the interference between the second clamping jaw 1511 and the first bearing table 12a, improving the safety and reliability of the operation; the process of the second clamping jaw 1511 entering the avoiding gap 124 itself also plays a role in auxiliary guiding and precise positioning, and when the posture of the sealing ring 252 is completely correct (i.e., the straight segment 2522 is aligned with the straight surface segment 25121, and the overall direction is correct), the second clamping jaw 1511 can smoothly enter the avoiding gap 124, thereby forming a mechanical self-correcting mechanism, further ensuring the assembly precision; the design of the avoiding gap 124 enables the second clamping jaw 1511 to release the sealing ring 252 in a state closer to the final assembly position, reducing the risk of free fall or deviation after release, and improving the stability of assembly.

[0067] In other embodiments, the second clamping jaw 1511 can also grasp the arc segment 2521 or the straight segment 2522.

[0068] In an embodiment, referring to Figure 9 , Figure 12 and Figure 13 , the assembly equipment of the dust collector bottom cover of the dust collector further includes a sealing ring warehouse 16 extending along the Z-axis direction, the sealing ring warehouse 16 includes an arc-shaped side plate 161 and a flat straight plate 162 connected to the edge of the two sides of the arc-shaped side plate 161, and a plurality of sealing rings 252 are sleeved on the outer periphery of the sealing ring warehouse 16; the sealing ring feeding module 15 further includes a material distribution assembly 152 and a material conveying assembly 153, and the base 10 further has a receiving position 110 and a feeding position 111, the material conveying assembly 153 is capable of moving relative to the base 10 between the receiving position 110 and the feeding position 111, the material distribution assembly 152 includes a material distribution fork 1521 capable of being inserted between the straight segments 2522 of the adjacent two sealing rings 252 on the sealing ring warehouse 16, so that the sealing ring 252 located below is detached from the sealing ring warehouse 16 and falls on the material conveying assembly 153 at the receiving position 110, and the sealing ring clamp 151 is capable of moving between the feeding position 111 and the second feeding station 102, and clamping the sealing ring 252 at the feeding position 111.

[0069] The seal ring hopper 16 is used as a storage and directional arrangement device for the seal ring 252, and is arranged along the Z-axis direction. The main structure of the seal ring hopper 16 includes an arc-shaped side plate 161 and two flat straight plates 162 connected to the edges of the arc-shaped side plate 161. The cross-sectional profile of the seal ring hopper 16 matches the outer profile of the seal ring 252. The arc-shaped side plate 161 corresponds to the arc segment 2521 of the seal ring 252, and the flat straight plate 162 corresponds to the straight segment 2522 of the seal ring 252. A plurality of seal rings 252 are sequentially arranged around the outer periphery of the seal ring hopper 16. In the sleeved state, the straight segment 2522 of each seal ring 252 naturally fits the area of the flat straight plate 162, and the arc segment 2521 fits the area of the arc-shaped side plate 161, effectively preventing the seal ring 252 from rotating or mispositioning in the seal ring hopper 16, achieving directional stacking and anti-rotation positioning of the seal ring 252 in the seal ring hopper 16, and avoiding the problem of direction disorder caused by chaotic stacking of the seal ring 252.

[0070] The material conveying assembly 153 can move relative to the base 10 between the receiving position 110 and the feeding position 111, for example, by sliding rails, belt conveying, or mechanical arms, etc. to realize horizontal translation. The function of the material conveying assembly 153 is to receive the single seal ring 252 separated from the seal ring hopper 16 and transfer it to the feeding position 111 for pickup by the seal ring clamp 151.

[0071] The material distribution assembly 152 includes a material distribution fork 1521, which can be precisely inserted into the gap between the straight segments 2522 of the adjacent two seal rings 252 at the bottom of the seal ring hopper 16 under the control of a driving mechanism such as a pneumatic cylinder or an electric push rod. Since the straight segments 2522 of the seal ring 252 are located in the area of the flat straight plate 162, the gap is clear and easy to position. After the material distribution fork 1521 is inserted, it can support the seal ring 252 above and release the seal ring 252 below. At this time, the bottom seal ring 252 will slide along the outer periphery of the seal ring hopper 16 under the action of gravity due to the loss of upper stacking pressure and lateral constraint, accurately falling out and falling on the material conveying assembly 153 at the receiving position 110. After the material conveying assembly 153 receives the single seal ring 252, it will be smoothly transported to the feeding position 111.

[0072] The sealing ring clamp 151 is activated, and its two second clamping jaws 1511 move to the feeding position 111 to precisely grab the connection between the arc segment 2521 and the straight segment 2522 of the sealing ring 252. Since the sealing rings 252 have been arranged in a directional manner in the hopper, and the feeding and conveying processes maintain a stable posture, the direction of the sealing ring 252 is always consistent when it is grabbed by the sealing ring clamp 151, providing a reliable guarantee for the subsequent precise assembly at the second feeding station 102. After completing the grabbing, the sealing ring clamp 151 moves along the Y-axis and Z-axis directions to transfer the sealing ring 252 from the feeding position 111 to the second feeding station 102 and accurately place it on the positioned cover body 251 in the predetermined posture (with the straight segment 2522 facing away from the second positioning column 122). The second clamping jaw 1511 will enter the avoidance notch 124 on the bearing table 12 during the placement process to ensure no interference and high-precision assembly.

[0073] In other embodiments, the sealing ring hopper 16 can also be flat, and multiple sealing rings 252 are laid flat on the flat plate for direct grabbing by the second clamping jaw 1511.

[0074] In an embodiment, referring to Figures 12 to 14 The assembly equipment for the dust collector bottom cover of the dust collector further includes a hopper disc 17 and a rotating assembly 18. The hopper disc 17 is provided with multiple sealing ring hoppers 16 spaced apart along its circumference. The rotating assembly 18 is drivingly connected to the sealing ring hoppers 16 to enable the sealing ring hoppers 16 to rotate along the circumference of the hopper disc 17. The conveying assembly 153 is arranged below the hopper disc 17. The hopper disc 17 is provided with a material passing opening 171 corresponding to the material receiving position 110 of the conveying assembly 153.

[0075] The hopper disc 17 has a disc-shaped structure and can be horizontally arranged on the base 10. Multiple sealing ring hoppers 16 are uniformly and spaced apart along the circumference of the hopper disc 17. Each sealing ring hopper 16 has a directional profile structure composed of an arc-shaped side plate 161 and a planar straight plate 162, which is used to set and orderly arrange multiple sealing rings 252. By arranging multiple sealing ring hoppers 16 on the hopper disc 17, the material carrying capacity and production continuity of the equipment are enhanced.

[0076] The rotating assembly 18 is drivingly connected to the hopper disc 17 and can be composed of a servo motor, gears, belts, or a direct driving mechanism, which can accurately control the intermittent rotation of the hopper disc 17 around its central axis (i.e., the circumferential center of the hopper disc 17). After each rotation, the hopper disc 17 accurately aligns the next sealing ring hopper 16 directly above the material receiving position 110, ensuring that the feeding and receiving actions of the feeding assembly 152 and the conveying assembly 153 are always completed at the same fixed station, simplifying the control logic of subsequent mechanical movements.

[0077] The material conveying assembly 153 is arranged below the magazine tray 17, and the magazine tray 17 is provided with a material passing opening 171 at the corresponding material receiving position 110. The material passing opening 171 is an opening structure penetrating through the magazine tray 17, and has a size sufficient to allow the material separating fork 1521 to be inserted and the sealing ring 252 to smoothly fall. When one of the sealing ring magazines 16 is driven to rotate to the position of the material passing opening 171 by the rotating assembly 18, the material separating fork 1521 can be inserted between the linear segments 2522 of the adjacent two sealing rings 252 in the sealing ring magazine 16 to perform the material separating action. The bottommost sealing ring 252 after being separated falls through the material passing opening 171 under the action of gravity and accurately falls onto the material conveying assembly 153 below.

[0078] The material conveying assembly 153 does not need to move with different positions of the sealing ring magazine 16 and always receives the sealing ring 252 at the material receiving position 110; and the magazine tray 17 rotates to sequentially send each sealing ring magazine 16 above the material passing opening 171 to complete the material supply switching. This not only reduces the movement stroke and control complexity of the material conveying assembly 153, but also improves the stability and beat consistency of the system operation.

[0079] In addition, this structure supports manual or automatic material changing operation. When the sealing rings 252 in one of the sealing ring magazines 16 are exhausted, the control system can instruct the rotating assembly 18 to automatically switch to the next sealing ring magazine 16 containing the sealing rings 252 to continue the material supply, thereby realizing non-stop material replenishment and greatly improving the equipment utilization rate. At the same time, the empty sealing ring magazine 16 can be sent to a position convenient for operation for manual replenishment or reloaded by an automatic feeding mechanism, facilitating maintenance and management.

[0080] In other embodiments, a plurality of sealing ring magazines 16 are placed on a magazine conveying line and sequentially move to the material supply position 111 along the conveying direction of the magazine conveying line.

[0081] In an embodiment, please refer to Figure 3 、 Figure 4 and Figure 15 , the base 10 further has a first pressing station 103 downstream of the second feeding station 102, and a bearing 19 is arranged between the first carrier 12a and the first turntable 11a, so that the first carrier 12a can rotate relative to the first turntable 11a. The assembly equipment of the dust collector bottom cover of the dust collector further comprises a first pressing module 13a, and the first pressing module 13a comprises a first pressing block 131 arranged above the first pressing station 103. One side wall of the first pressing block 131 facing the center of the first turntable 11a is an arc surface recessed away from the center of the first turntable 11a. The first pressing block 131 can move relative to the first turntable 11a along the axial direction of the first turntable 11a to abut against the upper end surface of the sealing ring 252 and drive the sealing ring 252 to be sleeved on the outer peripheral surface of the first boss 2512 along the axial direction of the sealing ring 252.

[0082] The first pressing station 103 is arranged downstream of the second feeding station 102 and is provided with a first pressing module 13a for axially pressing the preliminarily placed sealing ring 252 to realize final reliable assembly, so as to ensure that the sealing ring 252 can be completely and uniformly sleeved on the outer periphery of the first boss 2512 of the cover body 251, and avoid sealing failure caused by incomplete assembly, local lifting or uneven stress.

[0083] Specifically, the base 10 is provided with the first pressing station 103 which is located downstream of the second feeding station 102 and sequentially receives the carrier table 12 on which the sealing ring 252 has been placed, with the rotation of the first turntable 11a. The first pressing module 13a includes a first pressing block 131 arranged above the first pressing station 103. The first pressing block 131 can be driven by a pneumatic cylinder, an electric push rod or a hydraulic device and can move up and down along the axial direction (i.e. the Z-axis direction) of the first turntable 11a, so as to accurately abut against the upper end surface of the sealing ring 252 and apply a downward pressing force to drive the sealing ring 252 to gradually sleeve into the outer peripheral surface of the first boss 2512 along the axial direction until the sealing ring 252 is completely in place. The bearing 19 is arranged between the first carrier table 12a and the first turntable 11a, so that the first carrier table 12a can rotate around its central axis, and thus the position of the first pressing block 131 in the horizontal direction can remain unchanged, and the sealing ring 252 can be pressed all around.

[0084] It is worth mentioning that the side wall of the first pressing block 131 facing the center of the first turntable 11a is an arc surface recessed away from the center. The arc surface structure matches the profile of the outer periphery of the sealing ring 252 and is particularly suitable for pressing the arc segment 2521 of the sealing ring 252. The sealing ring 252 naturally conforms to the profile of the arc segment 25122 of the first boss 2512 during the pressing process, thereby improving the assembly compliance. For the straight segment 2522 of the sealing ring 252, the end portion of the first pressing block 131 extending in the arc direction can be used for pressing.

[0085] In other embodiments, the first pressing block 131 can also have a D shape, and its profile is adapted to the first boss 2512. The inner profile of the first pressing block 131 has a small gap with the outer peripheral surface of the first boss 2512, so that the first pressing block 131 can be sleeved on the outer periphery of the first boss 2512 and can press the sealing ring 252 downward to drive the sealing ring 252 to sleeve on the outer peripheral surface of the first boss 2512 along the axial direction.

[0087] The bottom cover 25 further comprises a seal buckle 253 capable of elastic deformation, and the cover body 251 is further provided with a second boss 2513 arranged on the first boss 2512 and surrounding the outer edge of the through hole 2511, and the seal buckle 253 is arranged on the second boss 2513 and at least partially located in the through hole 2511; the assembly device of the bottom cover of the dust collector of the dust collector further comprises a second turntable 11b arranged on the base 10, a seal buckle feeding module 21 and a transfer conveying module 20, the base 10 further comprises a third feeding station 105 and a fourth feeding station 107 located downstream of the third feeding station 105, and a first discharging station 104 located downstream of the second feeding station 102; the second turntable 11b is rotatable relative to the base 10 and can rotate between the third feeding station 105 and the fourth feeding station 107, and the plurality of carrying tables 12 comprises a second carrying table 12b arranged on the second turntable 11b, the transfer conveying module 20 is used for transferring the bottom cover 25 located at the first discharging station 104 to the third feeding station 105, and the seal buckle feeding module 21 is used for placing the seal buckle 253 on the cover body 251 of the second carrying table 12b located at the fourth feeding station 107.

[0088] The second rotating disc 11b, the sealing buckle feeding module 21 and the transfer conveying module 20 are additionally arranged on the base 10 and cooperated with the original assembly process. The third feeding station 105 and the fourth feeding station 107 downstream of the third feeding station 105 and the first discharging station 104 are arranged on the base 10. The first discharging station 104 is located after the first pressing station 103 and is the terminal station of the first rotating disc 11a process, used for receiving the bottom cover 25 semi-finished product after the sealing ring 252 is pressed. The second rotating disc 11b is independently arranged on the base 10, can rotate around the central axis thereof and rotate between the third feeding station 105 and the fourth feeding station 107. The second carrier table 12b installed on the second rotating disc 11b is included in the plurality of carrier tables 12 and has the same structure as the first carrier table 12a, is provided with the first positioning column 121 for positioning the cover body 251 and the second positioning column 122 and the positioning gap 123 for clamping the elastic buckle 2514, and ensures that the cover body 251 can also be accurately positioned in the second rotating disc 11b process.

[0089] The transfer conveying module 20 is used for picking up the bottom cover 25 (i.e. the semi-finished product containing the cover body 251 and the sealing ring 252) after the sealing ring 252 is assembled and pressed from the first discharging station 104 and accurately transferring the bottom cover 25 to the second carrier table 12b of the third feeding station 105. The transfer conveying module 20 can adopt a linear cylinder, a mechanical arm and the like in cooperation with a clamping jaw or a suction cup and the like structure to realize smooth and lossless workpiece transfer and ensure the continuity of the assembly process. When the second carrier table 12b with the bottom cover 25 semi-finished product is rotated from the third feeding station 105 to the fourth feeding station 107 by the second rotating disc 11b, the sealing buckle feeding module 21 is started. The sealing buckle feeding module 21 can accurately pick up the pre-arranged sealing buckle 253 and place the sealing buckle 253 on the second boss 2513 of the cover body 251 on the second carrier table 12b of the fourth feeding station 107, so that the sealing buckle 253 is correctly positioned and oriented and at least partially falls into the area of the through hole 2511, thereby preparing for the subsequent sealing cooperation with the flip cover.

[0090] The first rotating disc 11a system completes the feeding, positioning and pressing of the cover body 251 and the sealing ring 252, then transfers the bottom cover 25 semi-finished product to the second rotating disc 11b system through the transfer conveying module 20, and the second rotating disc 11b system completes the accurate assembly of the sealing buckle 253. The structure of the double rotating discs combined with the transfer conveying module 20 not only ensures the independent controllability of each assembly process, but also realizes the seamless connection of the overall process, avoids the efficiency reduction caused by process conflict or space interference. In addition, the assembly equipment also supports parallel operation, that is, when the first rotating disc 11a is performing a new round of cover body 251 and sealing ring 252 assembly, the second rotating disc 11b can simultaneously perform sealing buckle 253 assembly and discharging, which significantly improves the overall beat and capacity of the assembly equipment.

[0091] In other embodiments, the sealing buckle feeding module 21 can also complete feeding in the first rotary disc 11a system, so that the assembly device only needs to be provided with one discharging station and does not need to be provided with the transfer conveying module 20.

[0092] In an embodiment, referring to Figure 2 , Figure 4 and Figure 16 , the base 10 further has a dispensing station 106 between the third feeding station 105 and the fourth feeding station 107, and a bearing 19 is arranged between the second carrier 12b and the second rotary disc 11b, so that the second carrier 12b can rotate relative to the second rotary disc 11b; the assembly device of the dust collector bottom cover of the dust collector further comprises a dispensing module 22 arranged on the base 10, the dispensing module 22 comprises a dispensing valve 221 and a dispensing detection camera 222, the dispensing valve 221 can move along the Z-axis direction to dispense glue on the upper end surface of the second boss 2513 located on the dispensing station 106, and the dispensing detection camera 222 is arranged above the dispensing station 106.

[0093] The base 10 is provided with the dispensing station 106 between the third feeding station 105 (bottom cover 25 semi-finished product feeding) and the fourth feeding station 107 (sealing buckle 253 assembly). The dispensing station 106 is used for pretreating the cover body 251 positioned on the second carrier 12b, that is, applying an appropriate amount of glue on the upper end surface of the second boss 2513 to provide a bonding basis for subsequent installation of the sealing buckle 253. Since the sealing buckle 253 needs to bear elastic deformation and external pressure for a long time, the connection strength between the sealing buckle 253 and the cover body 251 can be significantly enhanced by dispensing fixation, so as to prevent displacement or failure and thus ensure the persistence of the sealing performance.

[0094] The bearing 19 is arranged between the second carrier 12b and the second rotary disc 11b, so that the second carrier 12b can freely rotate relative to the second rotary disc 11b around the central axis thereof to achieve comprehensive, stable and uniform dispensing effect. The relative position of the dispensing valve 221 in the horizontal plane remains unchanged, and the dispensing valve 221 moves up and down along the Z-axis direction to start glue application. The second carrier 12b rotates through the bearing 19, so that different regions on the circumferential surface of the second boss 2513 are aligned with the dispensing valve 221. In this way, the dispensing valve 221 moves without the second boss 2513, so as to avoid positioning deviation of the glue valve caused by the movement of the dispensing valve 221, thereby avoiding problems such as glue line deviation, uneven thickness or missing points, and improving the consistency of dispensing quality. The dispensing valve 221 is a precise fluid control device, which can be driven by a pneumatic, piezoelectric or screw type, and can accurately control the glue amount, glue discharge speed and trajectory. The dispensing valve 221 is installed on a linear module that can move along the Z-axis direction, and can be accurately lowered to a preset height at the dispensing station 106 to perform annular or point dispensing on the upper end surface of the second boss 2513, so as to ensure that the glue is uniformly distributed in the mounting area of the sealing buckle 253.

[0095] After dispensing is completed, the dispensing detection camera 222 is started. The dispensing detection camera 222 is arranged above the dispensing station 106, with the lens vertically downward, and can clearly capture the image of the dispensing area. Through image processing algorithms, the system can automatically judge whether the glue exists, the position is accurate, the glue amount is sufficient, there is no broken glue or overflow, and other defects. If the detection is unqualified, the system can issue an alarm or an instruction to transfer the module 20 to remove the workpiece, prevent defective products from flowing into the subsequent assembly link, and realize the quality closed-loop control of the whole process.

[0096] The sealing buckle 253 includes a first sealing section 2531, a second sealing section 2532, and a connecting section 2533 connecting the first sealing section 2531 and the second sealing section 2532. The diameter of the first sealing section 2531 is smaller than that of the second sealing section 2532. The first sealing section 2531 extends into the through hole 2511 and abuts the hole wall surface of the through hole 2511. The second sealing section 2532 protrudes from the second boss 2513. The connecting section 2533 has an abutting surface abutting the upper surface of the second boss 2513. That is, the abutting surface of the connecting section 2533 is bonded to the upper surface of the second boss 2513 by the glue dispensed by the dispensing valve 221. Further, the second sealing section 2532 and the connecting section 2533 jointly enclose a ring-shaped groove. The inner side wall of the groove abuts the hole wall surface of the through hole 2511. The outer side wall of the groove abuts the outer peripheral surface of the second boss 2513. The abutting surface of the connecting section 2533 serves as the groove bottom and is bonded to the upper surface of the second boss 2513.

[0097] In other embodiments, the second carrier 12b can be fixed relative to the second turntable 11b, and the dispensing valve 221 can move along the circumference of the second boss 2513 to dispense glue.

[0098] In an embodiment, referring to Figures 2 to 4 、 Figure 17 The assembly equipment of the dust collector bottom cover of the dust collector further includes a reverse material removal module 23. The reverse material removal module 23 includes a sealing buckle conveying assembly 231, a reverse material detection assembly 232, a reverse material pushing block 233, and a reverse material conveying assembly 234. The sealing buckle conveying assembly 231 includes a wire body 2311 and a conveying belt 2312 arranged on the wire body 2311. The sealing buckle 253 is placed on the conveying belt 2312 along the conveying direction of the conveying belt 2312. The reverse material detection assembly 232 and the reverse material pushing block 233 are arranged on one side of the wire body 2311 through a mounting bracket 235. The reverse material conveying assembly 234 is arranged on the other side of the wire body 2311 corresponding to the reverse material pushing block 233. When the reverse material detection assembly 232 detects that the sealing buckle 253 is a reverse material, the reverse material pushing block 233 can move the reverse material into the reverse material conveying assembly 234.

[0099] The assembly equipment for the dust collector bottom cover of the vacuum cleaner also includes a reverse material rejection module 23. The reverse material rejection module 23 is used to automatically detect the orientation of the sealing buckle 253 during the feeding process and separate defective products to ensure that the sealing buckle 253 is in the correct orientation before assembly. This prevents problems such as poor adhesion, sealing failure or assembly jamming caused by the sealing buckle 253 being placed in the wrong direction (such as the front and back sides being reversed or the inside and outside orientation being incorrect), thereby ensuring the reliability of subsequent assembly and product quality.

[0100] The backfill rejection module 23 mainly includes a sealing buckle conveying assembly 231, a backfill detection assembly 232, a backfill pusher 233, a backfill conveying assembly 234, and a mounting bracket 235 for support and positioning. The sealing buckle conveying assembly 231 includes a line body 2311 and a conveyor belt 2312 mounted thereon. The conveyor belt 2312 runs continuously or intermittently along the conveying direction, sequentially conveying the sealing buckles 253 to be assembled to the picking position of the sealing buckle loading module 21. When the sealing buckles 253 are placed on the conveyor belt 2312, they are already arranged in a preset posture (i.e., the second sealing section 2532 of the sealing buckle 253 is located above the first sealing section 2531, which is considered positive material) along the conveying direction.

[0101] On one side of the sealing buckle conveying assembly 231, a reverse material detection assembly 232 is fixedly mounted via a mounting bracket 235. The reverse material detection assembly 232 can employ a vision inspection system (such as an industrial camera with a light source), a contact sensor, or a laser sensor to scan passing sealing buckles 253 in real time. For example, a laser sensor can simultaneously emit two parallel laser beams in the vertical direction. Since the diameter of the second sealing section 2532 is larger than the diameter of the first sealing section 2531, if the upper laser beam is blocked while the lower laser beam passes smoothly, the sealing buckle 253 is considered positive. Conversely, if the upper laser beam passes smoothly while the lower laser beam is blocked, the sealing buckle 253 is considered reverse material. Furthermore, the reverse material detection assembly 232 can also determine the correct orientation of each sealing buckle 253 through image comparison or feature recognition algorithms. Once reverse material with an incorrect orientation is detected, the system immediately sends a signal to trigger a rejection action.

[0102] Installed on the same side as the backflow detection component 232 is a backflow pusher 233. The backflow pusher 233 can be driven by a cylinder, electric slide, or electromagnetic device. Upon receiving a detection signal, it can move quickly and accurately laterally (perpendicular to the conveying direction of the conveyor belt 2312), pushing the backflow-prone sealing buckle 253 off the conveyor belt 2312. On the other side of the sealing buckle conveying component 231, corresponding to the pushing path of the backflow pusher 233, is a backflow conveying component 234. When the backflow pusher 233 moves, the incorrectly oriented sealing buckle 253 is pushed off the conveyor belt 2312 and falls onto the backflow conveying component 234. It is then conveyed back to the sealing buckle hopper via the backflow conveying component 234, facilitating subsequent manual re-inspection, rework, or scrapping, preventing it from entering the normal process.

[0103] The reverse material rejection module 23 is typically located at the front or middle of the feeding path of the sealing buckle 253, for example, after the sealing buckle 253 separates from the sealing buckle hopper and before entering the sealing buckle feeding module 21. Through the real-time monitoring and automatic rejection function of the reverse material rejection module 23, the reverse sealing buckle 253 can be effectively prevented from entering the assembly stage due to human error in feeding or abnormal automatic arrangement, significantly reducing the assembly failure rate and product rework rate caused by incorrect orientation.

[0104] In other embodiments, the conveyor belt 2312 has two parallel extending channels, a first channel and a second channel. The sealing buckle 253 is conveyed from the first channel. A positive material buffer is provided on the outer side of the end of the first channel, and positive materials are conveyed to the positive material buffer via the first channel for the sealing buckle feeding module 21 to grab and feed. A reverse material conveying assembly 234 is provided on the outer side of the end of the second channel. A reverse material pusher 233 is located on the side of the first channel away from the second channel. When the reverse material detection assembly 232 detects that the current sealing buckle 253 is reverse material, the reverse material pusher 233 pushes the reverse material into the second channel, and the reverse material falls from the end of the second channel into the reverse material conveying assembly 234. There is no obstruction between the first channel and the second channel, at least on the movement path of the reverse material pusher 233, to allow the reverse material to change lanes.

[0105] In one implementation, please refer to Figure 2 , Figure 4 and Figure 18 The base 10 also has a second pressing station 108 and a product inspection station 109 located downstream of the fourth loading station 107. The assembly equipment for the dust collector bottom cover of the vacuum cleaner also includes a second pressing module 13b and a product inspection camera 24. The second pressing module 13b includes a second pressing block 132 and a downward pressing drive component 133 that drives the second pressing block 132. The second pressing block 132 is located above the second pressing station 108. When the second platform 12b moves to the pressing station, the downward pressing drive component 133 drives the second pressing block 132 to press down and tighten the sealing buckle 253. The product inspection camera 24 is located on the base 10 corresponding to the product inspection station 109. When the second platform 12b moves to the product inspection station 109, the product inspection camera 24 takes pictures and inspects the bottom cover 25.

[0106] Along the rotation direction of the second turntable 11b, the base 10 is sequentially equipped with a fourth loading station 107, a second pressing station 108 downstream of it, and a product inspection station 109 further downstream. A second pressing module 13b is provided at the second pressing station 108. The second pressing module 13b includes a second pressing block 132 and a downward pressing drive component 133 (such as a cylinder, electric push rod, or servo cylinder) that drives its movement. The second pressing block 132 is located above the second pressing station 108, and its lower surface shape matches the contour of the upper surface of the sealing buckle 253, or its lower surface is a flat surface, enabling full contact pressing. When the downward pressing drive component 133 is activated, the second pressing block 132 moves downward along the Z-axis, smoothly pressing against the upper end face of the sealing buckle 253, applying a preset pressure, causing the first sealing section 2531 of the sealing buckle 253 to extend into the through hole 2511, and the connecting section 2533 to completely adhere to the surface of the second boss 2513 that has been glued. This pressing process helps the adhesive spread evenly, eliminates air bubbles, and enhances the bonding strength of the bonding interface, ensuring that the sealing buckle 253 will not fall off or shift due to vibration, temperature changes, or repeated opening and closing during subsequent use.

[0107] After the pressing process is completed, the second platform 12b continues to rotate with the second turntable 11b to the product inspection station 109. The product inspection station 109 is equipped with a product inspection camera 24, which is mounted on the base 10 with its lens facing the bottom cover 25 on the platform 12. It can perform all-round image acquisition and analysis on the bottom cover 25 (including the cover body 251, sealing ring 252, and sealing buckle 253) that has been fully assembled at this station.

[0108] The product inspection camera 24 can inspect the following: whether the sealing ring 252 is fully fitted into the first boss 2512 without twisting or flipping; whether the sealing buckle 253 is correctly installed on the second boss 2513 and centered; whether there is insufficient glue, overflow, or breakage in the glue dispensing area; whether the sealing buckle 253 is pressed in place, whether the height meets the standard, and whether it is tilted; and whether the bottom cover 25 has any obvious appearance defects (such as damage, foreign objects, misassembly, etc.). The system automatically determines whether the product is qualified through a preset image recognition algorithm and uploads the results to the control system. The unloading module sorts the products according to the inspection results and sends them to the conveyor line. If the inspection is qualified, the bottom cover 25 can continue to flow to the second unloading station, where it can be taken out by the unloading robot or conveyor line and enter the packaging or the next process. If the inspection is unqualified, the system can trigger an alarm and separate the defective products through a rejection mechanism (such as a pusher cylinder) to prevent them from flowing into subsequent processes.

[0109] Furthermore, the product needs to be flipped using a flipping module before being unloaded; the product needs to be photographed to confirm its placement position before being placed on the conveyor belt.

[0110] Please see Figure 3 The assembly process of the bottom cover 25 of the dust collector bottom cover assembly equipment of the present invention is as follows:

[0111] The first loading station 101 loads the cover body 251: the first turntable 11a rotates the first platform 12a to the first loading station 101. The cover body loading module 14 is activated, and its first gripper 145 picks up a cover body 251 from the tray 142. During the movement, it rotates circumferentially according to the feedback from the positioning detection camera 143 to adjust its posture. Then, the first gripper 145 precisely places the cover body 251 on the first platform 12a. At this time, multiple first positioning pins 121 are inserted into the through holes 2511 of the cover body 251 or abut against the outer peripheral wall of the cover body 251. At the same time, the elastic buckles 2514 on the outer periphery of the cover body 251 are embedded in the positioning gap 123 between the two second positioning pins 122 to achieve precise positioning.

[0112] The second loading station 102 loads the sealing ring 252: the first turntable 11a rotates the first carrier 12a, which has already positioned the cover body 251, to the second loading station 102. The sealing ring loading module 15 is activated, and the sealing ring clamp 151 picks up a sealing ring 252 from the feeding position 111 (the connection between its straight segment 2522 and the arc segment 2521 is held by the second gripper 1511), and moves it above the second loading station 102. The sealing ring clamp 151 accurately places the sealing ring 252 on the outer periphery of the first boss 2512 of the cover body 251, and ensures that the straight segment 2522 of the sealing ring 252 faces the side away from the second positioning post 122 on the central axis of the carrier 12, thereby automatically aligning it with the straight segment 25121 on the first boss 2512.

[0113] The first pressing station 103 presses the sealing ring 252: The first turntable 11a continues to rotate, sending the cover body 251 equipped with the sealing ring 252 to the first pressing station 103. The first pressing block 131 of the first pressing module 13a moves downward along the axial direction, abutting against the upper end face of the sealing ring 252, and applying pressure.

[0114] The first unloading station 104 unloads semi-finished products: the bottom cover 25 semi-finished product with the sealing ring 252 pressed into place enters the first unloading station 104 along with the first turntable 11a, waiting for transfer.

[0115] Transfer to the second turntable 11b: The transfer conveyor module 20 starts, picks up the semi-finished bottom cover 25 with the sealing ring 252 assembled from the first unloading station 104, and accurately transfers it to the third loading station 105 of the second turntable 11b, placing it on the second platform 12b. The second platform 12b also achieves stable positioning of the cover body 251 through the positioning gap 123 between the first positioning post 121 and the second positioning post 122.

[0116] Pre-applying adhesive at dispensing station 106: The second turntable 11b rotates the semi-finished bottom cover 25 to dispensing station 106. The dispensing valve 221 of the dispensing module 22 descends along the Z-axis to perform circular or fixed-point dispensing on the upper surface of the second protrusion 2513 on the cover body 251. After dispensing is completed, the dispensing inspection camera 222 performs dispensing inspection to ensure the dispensing effect.

[0117] The fourth loading station 107 loads the sealing buckle 253: the second turntable 11b delivers the pre-applied adhesive-coated bottom cover 25 semi-finished product to the fourth loading station 107. The sealing buckle loading module 21 precisely places the correctly oriented sealing buckle 253, after being screened by the reverse material rejection module 23, onto the second boss 2513, ensuring that at least part of it is located within the through hole 2511, ready for pressing.

[0118] The second pressing station 108 presses the sealing buckle 253: the second turntable 11b continues to rotate to the second pressing station 108. The downward pressing drive 133 of the second pressing module 13b drives the second pressing block 132 to move downward, pressing the sealing buckle 253 onto the surface of the glued second boss 2513. Under pressure, the adhesive fully adheres and cures to form a base, ensuring that the sealing buckle 253 is firmly installed, providing a guarantee for establishing a sealed connection with the dust collector's flip cover.

[0119] Product inspection is conducted at product inspection station 109: The assembled bottom cover 25 enters product inspection station 109. Product inspection camera 24 takes pictures of the bottom cover 25 from all angles, and the system automatically detects key indicators such as the assembly status of the sealing ring 252, the position of the sealing buckle 253, the quality of glue application, and the overall appearance. Products that pass inspection enter the unloading process; unqualified products are automatically rejected to ensure the consistency of product quality leaving the factory.

[0120] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
