Description

Technical Field

[0001] This invention relates to the field of automated feeding equipment technology, and more particularly to a first sponge feeding device inside a roller brush. Background Technology

[0002] Robotic vacuum cleaners and handheld vacuum cleaners are commonly used floor cleaning devices. A common accessory in these devices is a roller brush for sweeping up debris and hair. The roller brush typically consists of a cylindrical tube with raised ribs or brush blades on its outer surface. (See reference...) Figures 1 to 3 The cylinder is typically made of soft rubber, and a drive shaft runs through it. The drive shaft has a raised rib and a stop in the middle, and an inner support rib in the middle of the cylinder. One end of the drive shaft is a one-piece molded limiting piece, and the other end has a separate, insertable limiting cap. Hollow cylindrical first and second sponges are fitted onto the drive shaft. The overall assembly process of the roller brush is as follows: the first sponge is fitted from the end of the drive shaft where the limiting cap is inserted; the first sponge passes through the stop of the drive shaft to the end near the limiting piece; then the drive shaft is inserted into the cylinder, passing through the inner support rib in the middle of the cylinder. Figure 3 (As shown), the second sponge is then fitted onto the end of the drive shaft near the limiting shaft cover, and finally the limiting shaft cover is installed to complete the assembly of the roller brush. However, in the above assembly process, the installation of the first sponge is currently done manually, resulting in low assembly efficiency. Furthermore, the first sponge passes through the stop in the middle of the drive shaft, which could damage the first sponge. Damage to the first sponge would lead to uneven support force on the cylinder, resulting in product quality issues.

[0003] Therefore, technical personnel in related fields need to develop the assembly of the first sponge of the roller brush to improve assembly efficiency, while ensuring that the sponge body is not damaged when the first sponge passes through the stop in the middle of the drive shaft. Summary of the Invention

[0004] In view of this, the present invention proposes a first sponge feeding device inside a roller brush, which realizes automatic assembly of the first sponge onto the drive shaft, improves assembly efficiency, and also solves the problem that the first sponge is easily damaged by the middle stop part when assembled onto the drive shaft.

[0005] The technical solution disclosed in this invention, a first sponge feeding device inside a roller brush, includes:

[0006] A feeding vibratory plate is used for vibrating and conveying hollow cylindrical sponges. The feeding vibratory plate is arranged at a high position and is connected to an output channel.

[0007] The rotating feeding mechanism is located at a low position. The lower end of the output channel is connected to the rotating feeding mechanism. The hollow cylindrical sponge is output from the feeding vibratory plate and falls onto the rotating feeding mechanism by gravity.

[0008] The first conveying mechanism is used to convey the drive shaft component of the roller brush. The drive shaft component is conveyed vertically and linearly to the side of the rotating feeding mechanism.

[0009] The second conveying mechanism is used to convey the sleeve.

[0010] A sleeve loading robot is located at one end of the second conveying mechanism and is used to load the sleeve onto the upper half of the transmission shaft component.

[0011] The sponge feeding robot picks up hollow cylindrical sponges from the rotating feeding mechanism, and puts the hollow cylindrical sponges onto the drive shaft component with a sleeve. The hollow cylindrical sponges pass through the sleeve and enter the lower half of the drive shaft.

[0012] The sleeve return robot is located at the other end of the second conveying mechanism. It is used to take out the sleeves on the drive shaft component equipped with hollow cylindrical sponges and place them back on the second conveying mechanism. The sleeves are circulated between the sleeve loading robot and the sleeve return robot of the second conveying mechanism.

[0013] Furthermore, the output channel includes two parallel channel grooves for conveying two hollow cylindrical sponges to the rotating feeding mechanism at one time. The output channel curves downward from horizontal to form a feeding slide. After being output by the feeding vibratory plate, the hollow cylindrical sponges slide down naturally to the rotating feeding mechanism under gravity.

[0014] The rotating feeding mechanism further includes a first drive motor and a disc. The output shaft of the first drive motor drives the disc to rotate circumferentially around the center of the disc. On the disc, two sets of first and second material cylinders are provided on each side symmetrically around the center for the hollow cylindrical sponge to fall into. The bottom of the first and second material cylinder sets is provided with a bottom plate. The bottom plate is provided with a first through hole. The diameter of the first through hole is smaller than the outer diameter of the hollow cylindrical sponge. An ejection mechanism is provided on the side of the first drive motor for ejecting the hollow cylindrical sponge from the first or second material cylinder set.

[0015] Furthermore, the ejection mechanism includes a first pushing cylinder that pushes vertically upwards and a smooth rod connected to the cylinder rod of the first pushing cylinder. The smooth rod is equipped with a bearing, so that the smooth rod passes through the first through hole of the bottom plate through the first pushing cylinder, pushing the hollow cylindrical sponge upwards.

[0016] The sponge feeding robot further includes a first column, a first base plate horizontally disposed at the upper end of the first column, a first slide rail disposed on the first base plate, a first slider disposed on the first slide rail, a second base plate vertically disposed on the first slider, a second slide rail disposed on the second base plate, a second slider disposed on the second slide rail, a first connecting bracket vertically disposed on the second slider, two hollow cylinders vertically disposed at the bottom of the first connecting bracket, a first Y-axis pushing cylinder disposed at the right end of the first base plate, and a first Z-axis pushing cylinder disposed at the upper end of the second base plate. A second through hole is provided on the first connecting bracket corresponding to the position of the hollow cylinder. The diameter of the second through hole is larger than the outer diameter of the sleeve and smaller than the outer diameter of the hollow cylindrical sponge.

[0017] When the rotating material feeding mechanism detects that there is a hollow cylindrical sponge in the first or second material cylinder group, the first or second material cylinder group is driven by the drive motor to rotate to the lower end of the hollow cylinder. The hollow cylindrical sponge is pushed out by the ejection mechanism. The outer diameter of the hollow cylindrical sponge in its natural state is slightly larger than the opening diameter of the hollow cylinder. The hollow cylindrical sponge deforms and enters the hollow cylinder without falling out.

[0018] Furthermore, a second connecting bracket is vertically provided on the side of the first connecting bracket. The second connecting bracket is provided with two elastic shafts, which are respectively on the same axis as the two hollow cylinders and are used to elastically press against the top of the sleeve.

[0019] Furthermore, a first through-beam photoelectric sensor is provided below the disc of the rotating feeding mechanism to detect whether there is a hollow cylindrical sponge in the first or second material cylinder group that has rotated to the lower end of the output channel.

[0020] Furthermore, the sleeve loading robot includes a second column, a third base plate horizontally disposed on the upper end of the second column, a third slide rail disposed on the third base plate, a third slider disposed on the third slide rail, a fourth base plate vertically disposed on the third slider, a fourth slide rail disposed on the fourth base plate, a fourth slider disposed on the third slide rail, a third connecting bracket vertically disposed on the fourth slider, two finger cylinders disposed at the bottom of the third connecting bracket, grippers disposed on the finger cylinders, a second Y-axis pushing cylinder disposed on the left side of the third base plate, and a second Z-axis pushing cylinder disposed on the upper end of the fourth base plate. The sleeve return robot has the same structure as the sleeve loading robot, and the sleeve return robot and the sleeve loading robot are arranged in mirror symmetry.

[0021] Furthermore, the second conveying mechanism includes support feet arranged on the same side of the sleeve loading robot and the sleeve return robot, a mounting bracket horizontally arranged on the upper end of the support feet, a first synchronous pulley and a second synchronous pulley respectively arranged at both ends of the mounting bracket, a synchronous belt arranged on the first synchronous pulley and the second synchronous pulley, a second drive motor arranged on the first synchronous pulley or the second synchronous pulley, and a plurality of protrusions for positioning and sleeve fitting of the sleeve are arranged at intervals on the synchronous belt, and a running groove of the synchronous belt is provided on the upper side of the mounting bracket.

[0022] Furthermore, a positioning cylinder mechanism is respectively set on the outer side of both ends of the mounting bracket. The positioning cylinder mechanism includes a fixed bracket, a second push cylinder set on the fixed bracket, and a push plate connected to the push rod of the second push cylinder. The front side of the push plate is provided with two C-shaped openings. The push plate is pushed by the second push cylinder, and the C-shaped openings of the push plate are inserted into the sleeve sleeved on the protrusion to stabilize the sleeve and prevent it from shaking.

[0023] The first sponge feeding device inside the roller brush designed by the present invention has at least the following beneficial effects:

[0024] 1. The hollow cylindrical sponge is fed by a feeding vibratory plate that vibrates for a certain distance, and then falls into the rotating feeding mechanism by gravity through a curved feeding chute, making the material output more energy-efficient.

[0025] 2. Before the hollow cylindrical sponge (first sponge) is fitted onto the drive shaft of the roller brush, a sleeve is first fitted onto the upper part of the drive shaft. The sleeve covers the ribs on the drive shaft. The smooth surface of the sleeve facilitates the hollow cylindrical sponge to pass smoothly into the lower part of the drive shaft, thus completing the feeding of the first sponge. This avoids the problem of damage to the inner wall of the hollow cylindrical sponge caused by the traditional manual feeding method, which involves passing through the ribs and stop parts.

[0026] 3. The sponge feeding robot is designed with a transmission structure that allows the Z-axis to move up and down and the Y-axis to move back and forth. It also features a hollow cylinder to house the hollow cylindrical sponge. The inner diameter of the hollow cylinder is slightly smaller than the outer diameter of the hollow cylindrical sponge, allowing the sponge to deform to fit snugly inside the cylinder without falling off. The deformation requirements for the hollow cylindrical sponge are not high, and a certain degree of deformation will not have any impact.

[0027] 4. This device, consisting of a feeding vibratory feeder, a rotating feeding mechanism, a first conveying mechanism, a second conveying mechanism, a sleeve feeding robot, a sponge feeding robot, and a sleeve return robot, forms a complete integrated first sponge feeding device within the roller brush. This achieves automated sponge feeding, improving feeding efficiency, reducing manual output costs, and ensuring product quality. Furthermore, the entire device has few easily damaged parts, stable operation, high feeding accuracy, simple and smooth operation, and low noise. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] Please refer to Figures 1 to 3This is a schematic diagram of the roller brush product structure for which the device designed in this invention is intended. This roller brush product is mainly used in robotic vacuum cleaners or handheld electric sweeping and mopping machines. The inner center of the plastic cylinder of the roller brush product has supporting ribs, and the drive shaft, fitted inside the plastic cylinder, has protruding ribs and a stop portion in its center. One end of the drive shaft is an integrally formed limiting piece, and the other end has a separate, insertable limiting shaft cap. Hollow cylindrical first and second sponges are fitted onto the drive shaft to uniformly fill the interior of the plastic cylinder, providing elastic internal support and enabling rapid rebound after deformation upon contact with the ground during use. Assembling the first sponge of this roller brush product is a challenge; therefore, this invention discloses the following implementation scheme to achieve automated assembly of the first sponge.

[0049] Please refer to Figures 4 to 13 This is a specific embodiment of a first sponge feeding device inside a roller brush provided by this technical solution.

[0050] The device includes a feeding vibratory plate 1, an output channel 2, a rotating feeding mechanism 3, a first conveying mechanism 4, a second conveying mechanism 5, a sleeve loading robot 6, a sponge loading robot 7, and a sleeve return robot 8. The feeding vibratory plate 1 is used for vibrating and conveying hollow cylindrical sponges 100. The feeding vibratory plate 1 is positioned at a high point and connected to the output channel 2. The rotating feeding mechanism 3 is positioned at a low point, with the lower end of the output channel 2 connected to the rotating feeding mechanism 3. After being output from the feeding vibratory plate 1, the hollow cylindrical sponges 100 fall onto the rotating feeding mechanism 3 by gravity. The first conveying mechanism 4 is used to convey the drive shaft component of the roller brush, which is vertically and linearly conveyed to the side of the rotating feeding mechanism 3. The second conveying mechanism 5 is used to convey the sleeve. The sleeve loading robot 6 is located at one end of the second conveying mechanism 5 and is used to place the sleeve onto the upper part of the drive shaft component. The robotic arm 7 obtains the hollow cylindrical sponge 100 from the rotating feeding mechanism 3 and places the hollow cylindrical sponge 100 onto the transmission shaft component with the sleeve. The hollow cylindrical sponge 100 passes through the sleeve and enters the lower half of the transmission shaft. The sleeve return robotic arm 8 is located on the other end of the second conveying mechanism 5 and is used to remove the sleeve from the transmission shaft component equipped with the hollow cylindrical sponge 100 and place it back on the second conveying mechanism 5. The sleeve is circulated between the sleeve feeding robotic arm 6 and the sleeve return robotic arm 8 of the second conveying mechanism 5.

[0051] The sleeve is a hollow cylindrical plastic tube with an open bottom and a closed top. As a preferred design, the outer diameter of the upper end of the sleeve gradually transitions from small to large from the lower end. This design is beneficial for the installation of the hollow cylindrical sponge 100, which passes through the sleeve and enters the predetermined position after the material is loaded.

[0052] Reference Figure 5Preferably, the output channel 2 includes two parallel channel grooves for conveying two hollow cylindrical sponges 100 to the rotating feeding mechanism 3 at one time. The output channel 2 curves downward from horizontal to form a feeding slide. After the hollow cylindrical sponges 100 are output by the feeding vibrating plate 1, they slide down naturally to the rotating feeding mechanism 3 under gravity.

[0053] Reference Figure 6 Preferably, the rotating feeding mechanism 3 includes a first drive motor 31 and a disk 32. The output shaft of the first drive motor 31 drives the disk 32 to rotate circumferentially around the center of the disk 32. On the disk 32, two first material cylinder groups 321 and second material cylinder groups 322 are provided on each side symmetrically around the center for the hollow cylindrical sponge 100 to fall into. The bottom of the first material cylinder group 321 and the second material cylinder group 322 is provided with a bottom plate 37. The bottom plate 37 is provided with a first through hole 371. The diameter of the first through hole 371 is smaller than the outer diameter of the hollow cylindrical sponge 100. The first drive motor 31 is provided with an ejection mechanism for ejecting the hollow cylindrical sponge 100 from the first material cylinder group 321 or the second material cylinder group 322.

[0054] Preferably, the ejection mechanism includes a first pushing cylinder 33 that pushes vertically upward and a smooth rod 34 connected to the cylinder rod of the first pushing cylinder 33. The smooth rod 34 is provided with a bearing 35, so that the smooth rod 34 passes through the first through hole 371 of the bottom plate 37 through the first pushing cylinder 33, and pushes the hollow cylindrical sponge 100 upward.

[0055] Reference Figures 7 to 9 Preferably, the sponge feeding robot 7 includes a first column 71, a first base plate 72 horizontally disposed on the upper end of the first column 71, a first slide rail 73 disposed on the first base plate 72, a first slider 74 disposed on the first slide rail 73, a second base plate 75 vertically disposed on the first slider 74, a second slide rail 76 disposed on the second base plate 75, a second slider 77 disposed on the second slide rail 76, a first connecting bracket 78 vertically disposed on the second slider 77, two hollow cylinders 79 vertically disposed at the bottom of the first connecting bracket 78, a first Y-axis pushing cylinder 701 disposed on the right side of the first base plate 72, and a first Z-axis pushing cylinder 702 disposed on the upper end of the second base plate 75. A second through hole 781 is provided on the first connecting bracket 78 corresponding to the position of the hollow cylinder 79. The diameter of the second through hole 781 is larger than the outer diameter of the sleeve and smaller than the outer diameter of the hollow cylindrical sponge 100.

[0056] The hollow cylindrical sponge 100 is pushed out and propelled onto the sponge loading robot 7 by the first material cylinder group 321 or the second material cylinder group 322 on the rotating feeding mechanism 3. The biggest advantage of this scheme is that the first material cylinder group 321 or the second material cylinder group 322 is coaxially connected with the hollow cylinder 79 of the sponge loading robot 7. The inner diameter of the hollow cylinder 79 is slightly smaller than the outer diameter of the hollow cylindrical sponge 100 in its natural state. In this way, the hollow cylindrical sponge 100 is pushed upward from the bottom by the smooth rod 34, and the hollow cylindrical sponge 100 deforms to a certain extent and enters the hollow cylinder 79. The elasticity generated by the hollow cylindrical sponge 100 itself ensures that the hollow cylindrical sponge 100 will not fall out after entering the hollow cylinder 79.

[0057] Reference Figure 14 Preferably, the lower opening of the hollow cylinder 79 is designed as an outwardly flared inner wall, which is more conducive to the entry of the hollow cylindrical sponge 100. At the same time, multiple ribs are provided on the inner wall of the hollow cylinder 79 along the axial direction. The ribs and the outwardly flared inner wall are smoothly transitioned. The ribs make it easier for the hollow cylindrical sponge 100 to enter the hollow cylinder 79 and prevent it from falling out.

[0058] When the rotating feeding mechanism 3 detects that there is a hollow cylindrical sponge 100 in the first material cylinder group 321 or the second material cylinder group 322, the first material cylinder group 321 or the second material cylinder group 322 is driven by the drive motor to rotate to the lower end of the hollow cylinder 79, and the hollow cylindrical sponge 100 is pushed out by the ejection mechanism. The outer diameter of the hollow cylindrical sponge 100 in its natural state is slightly larger than the opening diameter of the hollow cylinder 79. The hollow cylindrical sponge 100 deforms and enters the hollow cylinder 79 without falling out.

[0059] Preferably, a second connecting bracket 791 is vertically provided on the side of the first connecting bracket 78. The second connecting bracket 791 has two elastic shafts 793, which are coaxial with the two hollow cylinders 79, and are used to elastically press against the top of the sleeve. The elastic shafts 793 can be smooth shafts with springs sleeved on them. The upper end of the shaft passes through a connecting seat 792 on the second connecting bracket 791. The connecting seat 792 can be a linear bearing 35, and a limiting snap ring is provided at the upper end of the shaft.

[0060] Reference Figure 6 Preferably, a first photoelectric sensor 36 is provided below the disc 32 of the rotating feeding mechanism 3 to detect whether there is a hollow cylindrical sponge 100 in the first material cylinder group 321 or the second material cylinder group 322 that has rotated to the lower end of the output material channel 2.

[0061] Reference Figure 10Preferably, the sleeve loading robot 6 includes a second column 61, a third base plate 62 horizontally disposed on the upper end of the second column 61, a third slide rail 63 disposed on the third base plate 62, a third slider 64 disposed on the third slide rail 63, a fourth base plate 65 vertically disposed on the third slider 64, a fourth slide rail 66 disposed on the fourth base plate 65, a fourth slider 67 disposed on the third slide rail 63, a third connecting bracket 68 vertically disposed on the fourth slider 67, two finger cylinders 69 disposed at the bottom of the third connecting bracket 68, grippers disposed on the finger cylinders 69, a second Y-axis push cylinder 601 disposed on the left side of the third base plate 62, and a second Z-axis push cylinder 602 disposed on the upper end of the fourth base plate 65. The sleeve return robot 8 has the same structure as the sleeve loading robot 6, and the sleeve return robot 8 and the sleeve loading robot 6 are arranged in a mirror symmetrical manner. Figure 12 (As shown).

[0062] Reference Figure 11 Preferably, the second conveying mechanism 5 includes support feet 51 respectively arranged on the same side of the sleeve loading robot 6 and the sleeve return robot 8, a mounting bracket 52 horizontally arranged on the upper end of the support feet 51, a first synchronous pulley 53 and a second synchronous pulley 54 respectively arranged at both ends of the mounting bracket 52, a synchronous belt 55 arranged on the first synchronous pulley 53 and the second synchronous pulley 54, a second drive motor 56 arranged on the first synchronous pulley 53 or the second synchronous pulley 54, a plurality of protrusions 551 for positioning and sleeved sleeve are arranged at intervals on the synchronous belt 55, and a running groove of the synchronous belt 55 is provided on the upper side of the mounting bracket 52.

[0063] Preferably, a positioning cylinder mechanism is provided on the outer side of each end of the mounting bracket 52. The positioning cylinder mechanism includes a fixed bracket 57, a second push cylinder 58 provided on the fixed bracket 57, and a push plate 59 connected to the push rod of the second push cylinder 58. The front side of the push plate 59 is provided with two C-shaped openings 591. The push plate 59 is pushed by the second push cylinder 58, and the C-shaped openings 591 of the push plate 59 are inserted into the sleeve sleeved on the protrusion 551 to stabilize the sleeve and prevent it from shaking.

[0064] Reference Figure 13 As the first transmission mechanism 4, this mechanism is a linear transmission drive shaft mechanism. It can be selected to adopt a transmission mechanism that combines a chain and a slide rail. This structure is a common technical means in the relevant technical field. A fixture for fixing the transmission shaft is set on the slide rail. The fixture is driven by a chain, and the chain is driven by a transmission gear set on the output shaft of the drive motor.

[0065] Reference Figures 4 to 15The overall working process of the first sponge feeding device in the roller brush of this scheme is as follows: First, the hollow cylindrical sponge 100 material is poured into the feeding vibrating plate 1. The hollow cylindrical sponge 100 is output by the vibration of the feeding vibrating plate 1. The hollow cylindrical sponge 100 falls into the first material cylinder group 321 or the second material cylinder group 322 of the rotating feeding mechanism 3 through the output material channel 2. The first photoelectric sensor 36 detects the presence of hollow cylindrical sponge 100, that is, the first drive motor 31 drives the disc 32 to rotate. The first material cylinder group 321 or the second material cylinder group 322 containing the hollow cylindrical sponge 100 rotates to the position where the opening faces the lower end of the hollow cylinder 79 of the sponge feeding robot 7. The lifting mechanism is started to push the hollow cylindrical sponge 100 into the hollow cylinder 79.

[0066] At the same time, the transmission shaft driven by the first conveying mechanism 4 reaches the side of the sleeve loading robot 6, and the sleeve loading robot 6 places the sleeve onto the transmission shaft. Figure 13 As shown), the first conveying mechanism 4 drives the transmission shaft with the sleeve sleeve to move forward to the side of the sponge feeding robot 7. At this time, the sponge feeding robot 7 moves the hollow cylinder 79 above the transmission shaft by pushing the cylinder 701 on the first Y-axis, and then moves the hollow cylinder 79 downward to be sleeved on the transmission shaft by pushing the cylinder 702 on the first Z-axis. The hollow cylindrical sponge 100 passes through the sleeve on the upper part of the transmission shaft and enters the lower half of the transmission shaft. Due to the deformation of the hollow cylindrical sponge 100 after entering the lower half of the transmission shaft, the hollow cylindrical sponge 100 is restricted to the lower half of the transmission shaft by the stop part on the transmission shaft. When the cylinder 702 on the first Z-axis lifts the hollow cylinder 79, it will not bring the hollow cylindrical sponge 100 out, thus completing the first sponge feeding in the roller brush.

[0067] When the drive shaft with the hollow cylindrical sponge 100 is mounted continues to move forward to the side of the sleeve return manipulator 8, the sleeve return manipulator 8 picks up the sleeve on the drive shaft and places it back onto the protrusion 551 of the synchronous belt 55 of the second conveying mechanism 5.
