Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaner assembly, and specifically to a high-efficiency assembly device and method for vacuum cleaners. Background Technique

[0002] Vacuum cleaners can be divided into upright, horizontal, and portable types according to their structures. They mainly consist of three parts: dust raising, dust suction, and dust filtering. When the internal motor of a vacuum cleaner works, it drives the blades to rotate at high speed, generating a negative air pressure inside the sealed housing to suck dust debris; during the production process of vacuum cleaners, most are assembled manually.

[0003] In the prior art, Chinese Utility Model with publication number CN212265641U discloses a vacuum cleaner housing assembly device. By providing a clamping part and using the relative clamping of a locking plate and a positioning plate, the vacuum cleaner housing and the body can be clamped and positioned for subsequent assembly.

[0004] However, currently, for the vacuum cleaner body conveyed on the conveyor belt, when only horizontally clamping it, the friction generated between the conveyor belt and the bottom of the vacuum cleaner body easily causes the vacuum cleaner body to tip over, resulting in difficulties in subsequent assembly work and affecting the assembly efficiency. For this reason, the present invention proposes a high-efficiency assembly device and method for vacuum cleaners to solve the above problems. Summary of the Invention

The rotating rod is rotatably mounted in the inner cavity of the rotating groove and adapted thereto. A side surface of the mounting plate is provided with an oblique groove with a triangular cross section. The oblique groove is located at the lower side of the rotating groove and is connected thereto.

[0012] An avoidance groove that passes through the mounting plate is opened in the middle of the rotating groove, a special-shaped worm gear is fixedly installed in the middle of the rotating rod, and the special-shaped worm gear is located in the inner cavity of the avoidance groove.

[0015] Preferably, both ends of the outer side wall of the adjusting cylinder are fixedly sleeved with limit rings, and a rotating groove for installing the adjusting cylinder is opened through the surface of the vertical plate, and the two limit rings are respectively located on the two side surfaces of the vertical plate and keep in contact with the vertical plate, and a plurality of connecting columns distributed in a ring array are fixedly installed between one end face of the adjusting cylinder and the mounting plate.

[0018] A vacuum cleaner assembly method, using the above-mentioned vacuum cleaner efficient assembly equipment, specifically includes the following steps:

[0019] Step 1: When the conveyor belt on the workbench surface transports the vacuum cleaner body to between the two clamping plates, the drive motor starts to work and drives the drive worm to rotate through the belt.

The rotating frame itself is retractable and has a built-in thrust spring. The middle and end portions of the rotating frame are respectively rotatably connected to the mounting plate and the clamping plate. When the vacuum cleaner body is transported between the two clamping plates, the rotating frame rotates and drives the two clamping plates to approach each other until the vacuum cleaner body is clamped. After the rotating frame rotates to a horizontal position, the thrust generated by the internal thrust spring on the clamping plate can stably clamp the vacuum cleaner body. During the rotation of the rotating frame, the clamping plate can also move upward and drive the vacuum cleaner body to move upward until it is separated from the conveyor belt, thereby avoiding itself from tipping over and ensuring that subsequent assembly work is carried out normally.

DETAILED DESCRIPTION

[0035] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 10 , the present invention provides a technical solution:

[0037] Example 1, a high-efficiency assembly device for a vacuum cleaner, comprising: a workbench 1.

[0038] Specifically, on both sides of the upper surface of the workbench 1, vertical plates 2 are fixedly installed. In the middle of the upper surface of the workbench 1, a conveyor belt is provided. The two vertical plates 2 are respectively located on both sides of the conveying direction of the conveyor belt. In the middle of the vertical plate 2, an adjusting cylinder 3 is rotatably installed. On one side surface of the two adjusting cylinders 3 close to each other, a mounting plate 4 is fixedly installed. When the adjusting cylinder 3 rotates, it can drive the mounting plate 4 to rotate synchronously, and thus the angle of the mounting plate 4 can be adjusted. On one side of the two mounting plates 4 close to each other, clamping plates 5 are provided. The clamping plates 5 are arranged in an arc structure, and rubber strips 51 are provided on the inner wall. A vacuum cleaner body 6 is clamped between the two clamping plates 5. As shown in Figure 1 and Figure 3 , the vacuum cleaner body 6 itself is in a cylindrical structure. The clamping plates 5 are arranged in a circular arc shape consistent with the surface radian thereof. When the two clamping plates 5 approach each other, they can respectively clamp and position the vacuum cleaner body 6 from both sides thereof. And the rubber strips 51 on the inner wall of the clamping plates 5 can improve the protection effect on the vacuum cleaner body 6, avoid damage to the vacuum cleaner body 6, and at the same time increase the friction force at the contact position between the two, avoiding the vacuum cleaner body 6 from separating from between the two clamping plates 5.

[0039] Secondly, between the mounting plate 4 and the clamping plate 5, two rotating frames 7 are arranged in an up-and-down distribution. The rotating frames 7 are arranged in a "C" shape. The middle of the rotating frame 7 is rotatably connected to the mounting plate 4. Both ends of the rotating frame 7 are arranged in a telescopic structure and a thrust spring 74 is内置. The end of the rotating frame 7 is rotatably connected to the clamping plate 5. Combining with Figure 4 and Figure 2 , a parallelogram structure is formed among the mounting plate 4, the clamping plate 5 and the two rotating frames 7. And because the rotating frame 7 can rotate, the distance between the mounting plate 4 and the clamping plate 5 is adjustable. That is to say, when the two rotating frames 7 rotate synchronously and in the same direction, the position where the clamping plate 5 is located can be changed, and the clamping plate 5 can always be parallel to the mounting plate 4. Moreover, when the rotating frame 7 rotates to drive the clamping plate 5 to move, the moving track of the clamping plate 5 is a circular arc. The clamping plate 5 can not only approach the vacuum cleaner body 6 to clamp the vacuum cleaner body 6, but also lift the vacuum cleaner body 6 through the friction force, separating the vacuum cleaner body 6 from the conveyor belt below it, thereby avoiding the vacuum cleaner body 6 from tipping due to the friction force between the bottom of the vacuum cleaner body 6 and the conveyor belt.

[0040] Further, an auxiliary support rod 8 is provided on one side of the clamping plate 5. One end of the auxiliary support rod 8 abuts against the inner side of the handle of the vacuum cleaner body 6 from bottom to top. The auxiliary support rod 8 is located outside a rotating frame 7 and rotates synchronously with the rotating frame 7. As Figure 3 shown, the surface of the vacuum cleaner body 6 also has a handle. The overall center of gravity of the vacuum cleaner body 6 is located between the vacuum cleaner body 6 itself and the handle. When the vacuum cleaner body 6 is lifted, one end of the auxiliary support rod 8 abuts against the inner side of the handle to achieve a supporting effect on the handle, which can prevent the vacuum cleaner body 6 from tilting due to the offset of the center of gravity.

[0041] To supplement the description of the structure of the rotating frame 7, the rotating frame 7 of the present application includes a rotating rod 71 in the middle. Both ends of the rotating rod 71 are fixedly connected with receiving cylinders 72 perpendicular to it, thus forming a "C" - shaped structure. One end of the inner cavity of the receiving cylinder 72 is movably inserted with a movable rod 73. The movable rod 73 can only be telescoped along the length direction of the receiving cylinder 72 and will not be separated from the receiving cylinder 72. One end of the movable rod 73 is fixedly connected with a kit 75. The outer wall of the clamping plate 5 is provided with a rotating shaft 76. The two kits 75 are respectively rotatably sleeved outside both ends of the rotating shaft 76. That is to say, one end of the movable rod 73 is rotatably connected to the clamping plate 5. When the whole rotating frame 7 rotates, the clamping plate 5 only moves in position, and the clamping plate 5 itself still remains in a vertical state without tilting.

[0042] To limit the rotation angle of the rotating frame 7, the thrust spring 74 of the present application is located in the inner cavity of the receiving cylinder 72 and abuts against the other end of the movable rod 73. The thrust spring 74 is always in a compressed state to ensure that the movable rod 73 is always in an extended state. The other end of the movable rod 73 is fixedly provided with a limiting block 731 that slides in the inner cavity of the receiving cylinder 72. The setting of the limiting block 731 is used to prevent the movable rod 73 from detaching from the inner cavity of the receiving cylinder 72. A rotating groove 41 is opened inside the mounting plate 4. The rotating rod 71 is rotatably installed in the inner cavity of the rotating groove 41 and is adapted to it. The inner diameter of the rotating groove 41 is smaller than the thickness of the mounting plate 4. The rotating rod 71 can only rotate along its own axis direction inside the mounting plate 4. A beveled groove 43 with a triangular cross - section is opened on one side surface of the mounting plate 4. The beveled groove 43 is located below the rotating groove 41 and is communicated with it. The setting of the beveled groove 43 is used to limit the overall rotation angle of the rotating frame 7. Specifically: when the rotating frame 7 rotates downward around the rotating rod 71, the maximum stroke is until the receiving cylinder 72 contacts the bottom of the beveled groove 43; when the rotating frame 7 rotates upward around the rotating rod 71, the maximum stroke is until the receiving cylinder 72 is in a horizontal state.

[0043] In order to drive the rotating frame 7 to rotate, the present application also has an avoidance groove 42 that penetrates the mounting plate 4 in the middle of the rotating groove 41, and a special-shaped worm gear 77 is fixedly installed in the middle of the rotating rod 71, and the special-shaped worm gear 77 is located in the inner cavity of the avoidance groove 42. The special-shaped worm gear 77 can only rotate in the inner cavity of the avoidance groove 42, and the special-shaped worm gear 77 rotates synchronously with the rotating rod 71. The special-shaped worm gear 77 is arranged in a fan shape. When the rotating frame 7 rotates downward as a whole and drives the clamping plate 5 close to the mounting plate 4, the special-shaped worm gear 77 7 and the clamping plate 5 are respectively located on both sides of the mounting plate 4, so as to avoid collision between the two. The other side of the mounting plate 4 is rotatably mounted with a driving worm 46 through the worm rack 44, and the driving worm 46 is engaged with the special-shaped worm gear 77. When the driving worm 46 rotates, it can drive the special-shaped worm gear 77 to rotate, thereby driving the rotating frame 7 to rotate as a whole. Since the rotatable angular stroke of the rotating frame 7 as a whole is less than ninety degrees, the special-shaped worm gear 77 and the driving worm 46 will not be separated from each other.

[0044] In order to install the auxiliary support rod 8, the present application also has a shaft rod 45 fixedly installed on the side of the mounting plate 4, and the shaft rod 45 movably passes through the other end of the auxiliary support rod 8. The shaft rod 45 is colinear with a rotating rod 71, and the auxiliary support rod 8 can rotate around the shaft rod 45. One end of the rotating shaft 76 extends outward to form an extension section 761, and the extension section 761 movably passes through the middle part of the auxiliary support rod 8. The extension section 761 is set to limit one end of the auxiliary support rod 8 to ensure that the rotation direction and angle of the auxiliary support rod 8 are consistent with the rotating frame 7. Therefore, while the clamping plate 5 clamps and positions the vacuum cleaner body 6, the auxiliary support rod 8 can support the handle of the vacuum cleaner body 6, thereby preventing the vacuum cleaner body 6 from tilting due to the shift of the center of gravity.

[0045] In order to drive the driving worm 46 to rotate, the present application also has a motor base 33 and a reinforcing cross plate 34 fixedly arranged in the inner cavity of the adjusting cylinder 3, and a driving motor 48 is fixedly installed on the surface of the motor base 33. The output end of the driving motor 48 and the middle part of the driving worm 46 are fixedly installed with pulleys 47. The two pulleys 47 are driven by a belt. When the driving motor 48 is working, it can drive the driving worm 46 to rotate, and the meshing transmission between the driving worm 46 and the special-shaped worm gear 77 is unidirectional. Therefore, when the driving motor 48 stops working, the rotating frame 7 as a whole can maintain a stable position and will not rotate easily. The output end of the driving motor 48 moves through the middle part of the reinforcing cross plate 34 and is rotatably connected to it. The setting of the reinforcing cross plate 34 is used to position the output end of the driving motor 48 to ensure that the belt conveyor between the two pulleys 47 is in a taut state.

[0046] To connect the adjusting cylinder 3 to the vertical plate 2, the present application further has limiting retaining rings 31 fixedly sleeved at both ends of the outer side wall of the adjusting cylinder 3. A rotating groove 21 for installing the adjusting cylinder 3 is penetrated and opened on the surface of the vertical plate 2. The two limiting retaining rings 31 are respectively located on both sides of the vertical plate 2 and are kept in contact with the vertical plate 2. The adjusting cylinder 3 itself can only rotate and will not be separated from the vertical plate 2. A plurality of connecting columns 32 distributed in an annular array are fixedly installed between one end face of the adjusting cylinder 3 and the mounting plate 4. By rotating the adjusting cylinder 3, the staff can adjust the angle of the mounting plate 4 to ensure that the clamping plate 5 can be more perfectly fitted with the vacuum cleaner body 6.

[0047] To drive the rotation of the adjusting cylinder 3, the present application further has a backing plate 35 and a clamping plate 36 fixedly installed on the other end face of the adjusting cylinder 3. An adjusting handle 37 is penetrated through the inner cavity of the clamping plate 36, and one end of the adjusting handle 37 is fixedly connected to the backing plate 35 by a bolt. The clamping plate 36 is arranged in a "U" - shaped structure for positioning the middle part of the adjusting handle 37 to prevent the adjusting handle 37 from rotating around one of its ends. That is to say, by pulling the adjusting handle 37, the staff can drive the adjusting cylinder 3 to rotate. The other end of the adjusting handle 37 is connected to an adjusting slider 23 by a bolt, and the adjusting slider 23 is slidably installed on the surface of the vertical plate 2.

[0048] To position the rotation of the adjusting cylinder 3, the present application further has an adjusting chute 22 and a scale 24 opened on the surface of the vertical plate 2. The adjusting slider 23 is slidably installed in the inner cavity of the adjusting chute 22. As Figure 9 shown, both the adjusting chute 22 and the scale 24 are arranged in an arc shape and are concentric with the rotating groove 21. A small hole is opened at the end of the adjusting handle 37 for corresponding to the scale 24, which can be used by the staff to observe the inclination angle of the adjusting handle 37. A threaded jack 231 is opened in the middle of the surface of the adjusting slider 23. Friction lines 232 are arranged on both sides of the surface of the adjusting slider 23. The thickness of the adjusting slider 23 is less than the depth of the adjusting chute 22. After loosening the bolt between the adjusting handle 37 and the adjusting slider 23, the adjusting handle 37 can drive the adjusting cylinder 3 to rotate. After tightening the bolt between the adjusting handle 37 and the adjusting slider 23, the friction lines 232 on the surface of the adjusting slider 23 can increase the friction force with the inner wall of the adjusting chute 22, thereby realizing the positioning of the adjusting handle 37 and further positioning the adjusting cylinder 3 to prevent the adjusting cylinder 3 from rotating easily.

[0049] The present invention also discloses a vacuum cleaner assembly method, which uses the above - mentioned high - efficiency vacuum cleaner assembly equipment and specifically includes the following steps:

[0050] Step 1. When the conveyor belt on the surface of the workbench 1 transports the vacuum cleaner body 6 to between the two clamping plates 5, the drive motor 48 works and drives the drive worm 46 to rotate through the belt. The drive worm 46 drives the rotating rod 71 and the storage tube 72 to rotate through the meshing transmission with the special-shaped worm gear 77, thereby driving the clamping plates 5 to move. At this time, the two clamping plates 5 approach each other and clamp the vacuum cleaner body 6.

[0051] Step 2. After the clamping plate 5 is in contact with the surface of the vacuum cleaner body 6, the rotating frame 7 continues to rotate, and the thrust spring 74 is compressed until the rotating frame 7 rotates to a horizontal position. The thrust spring 74 is compressed to the maximum, and the clamping plate 5 generates the maximum clamping force on the vacuum cleaner body 6. Since the moving trajectory of the clamping plate 5 is arc-shaped, the clamping plate 5 can also drive the vacuum cleaner body 6 to move upward a certain distance after clamping the vacuum cleaner body 6. Finally, the vacuum cleaner body 6 is clamped by the clamping plates 5 on both sides and remains suspended under the action of friction, separated from the conveyor belt.

[0052] Step 3: Start the manipulator above the vacuum cleaner body 6 to buckle the shell onto the outer side of the upper end of the vacuum cleaner body 6, and then use the power equipment to rotate and tighten the screws, bolts and other fasteners on the shell.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
