[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Depend on Figure 1-9 given;

[0031] Reference Figure 1 The brush to be assembled includes a bottom cover body 1, a connecting tube body 2, a brush filament 3 and a column body 4 which are arranged in sequence from bottom to top; wherein the interior of the bottom cover body 1 is connected with an integrated central tube 101, and the interior of the column body 4 forms an open groove 401 and two side grooves 402 which are connected with the open groove 401. During assembly, after the brush filament 3 is placed in the open groove 401, the column body 4 is pressed into the interior of the connecting tube body 2 by pressing, wherein the interior of the central tube 101 is provided with a convex column which is integrated with the bottom cover body 1. After the pressing is completed, the convex column can enter the open groove 401 in the column body 4 to extrude the pressed brush filament 3 to improve the stability of the connection, thereby completing the assembly process.

[0032] Reference Figure 2-3The present invention relates to an automated mechanical structure for brush assembly, comprising a bottom cover conveying mechanism 5, a connecting tube conveying mechanism 6, a column conveying mechanism 7 and a mechanical pressing mechanism 8 which are arranged in sequence from bottom to top, wherein one of the bottom cover holes 501 on the bottom cover conveying mechanism 5, one of the connecting tube holes 601 on the connecting tube conveying mechanism 6 and the column hole 701 at the end of the column conveying mechanism 7 are coaxially arranged to form a waiting assembly station; the mechanical pressing mechanism 8 comprises a first lifting member 801, a mounting frame 802, a second lifting member 803, a pressing plate 804, a connecting frame 805 and an annular frame 806, wherein the first lifting member 801 is fixedly arranged, the mounting frame 802 is fixedly arranged on the first lifting member 801, the second lifting member 803 is fixedly arranged on the mounting frame 802, the pressing plate 804 is fixedly arranged on the second lifting member 803, and the annular frame 806 is fixedly arranged on the mounting frame 802 through the connecting frame 805;

[0033] With such a design, when in use, the bottom cover body 1 is conveyed by the bottom cover conveying mechanism 5, the connecting tube body 2 is conveyed by the connecting tube conveying mechanism 6, and the column body 4 is conveyed by the column conveying mechanism 7. When the bottom cover body 1, the connecting tube body 2 and the column body 4 all enter the assembly station, the brush filament 3 is inserted into the open groove 401 in the column body 4 manually or mechanically, and then the column body 4 is pressed by the mechanical pressing mechanism 8, so that the column body 4 with the brush filament 3 enters the interior of the connecting tube body 2, and the connecting tube body 2 enters the interior of the central tube 101. At this time, under the extrusion of the column body 4, the connecting tube body 2 squeezes the central tube 101, thereby improving the connection strength between the two. The specific process is:

[0034] First, the first lifting member 801 drives the mounting frame 802 to move, and the mounting frame 802 drives the annular frame 806 to move through the connecting frame 805, so that the annular frame 806 moves down and is sleeved on the outside of the column body 4, and then the brush 3 can be inserted into the open groove 401 in the column body 4, and then the second lifting member 803 drives the pressing plate 804 to press down, so that the outer wall of the top of the column body 4 contacts the annular frame 806 after the column body 4 moves down. At this time, under the action of the annular frame 806, the brush 3 is stored in the side groove 402 on the column body 4. In this way, the brush wire 3 can be prevented from excessively contacting the inner wall of the connecting tube body 2 during the falling process, thereby preventing the brush wire 3 from being of different lengths after installation due to friction. Finally, the first lifting member 801 drives the mounting frame 802 to move, so that the pressing plate 804 moves downward and squeezes the column body 4, and finally the column body 4 enters the interior of the connecting tube body 2, and the connecting tube body 2 enters the interior of the central tube 101, completing the installation process. The assembly process of the brush wire 3, the connecting tube body 2 and the bottom cover body 1 can be realized by a one-time pressing, which is relatively convenient.

[0035] Specifically, the outer diameter of the annular frame 806 is larger than the outer diameter of the top end of the column body 4 to be assembled, and the outer diameter of the annular frame 806 is smaller than the outer diameter of the bottom end of the column body 4 to be assembled;

[0036] This design can prevent the annular frame 806 from contacting the inner wall of the connecting pipe body 2, so that the annular frame 806 can be removed from the connecting pipe body 2 after assembly.

[0037] Reference Figure 4-5 In order to further improve the stability of the brush filament 3 during the pressing process, hollow channels that are interconnected are formed inside the connecting frame 805 and inside the annular frame 806. The hollow channel on the connecting frame 805 is fixedly connected to the pump body 10, and the pump body 10 is fixedly connected to the water tank 11 through a conduit. The inside of the annular frame 806 is symmetrically fixedly connected with a telescopic positioning member 12;

[0038] The positioning member 12 includes two telescopic rods 13 and a plate body 14; wherein the telescopic rod 13 includes an outer cylinder 1301, an inner cylinder 1302 and a telescopic spring 1303, wherein the outer cylinder 1301 is fixedly connected with the hollow channel in the annular frame 806, the inner cylinder 1302 is T-shaped and slidably arranged inside the outer cylinder 1301, the telescopic spring 1303 surrounds the inner cylinder 1302, the inner cylinder 1302 is fixedly connected with the hollow groove 1401 in the plate body 14, and a positioning block 1402 is slidably arranged inside the hollow groove 1401;

[0039] With this design, when in use, after the brush filament 3 enters the open groove 401 in the column body 4, and the annular frame 806 is located on the outer wall of the bottom end of the column body 4, the water in the water tank 11 is sequentially passed through the hollow channel in the connecting frame 805 and the hollow channel in the annular frame 806 by the pump body 10 into the interior of the outer cylinder 1301, which will cause the inner cylinder 1302 to extend out of the outer cylinder 1301 and drive the plate body 14 to move outward. Subsequently, under the action of liquid pressure, the positioning block 1402 extends out of the hollow groove 1401 to fix the brush filament 3 from below. In this way, the brush filament 3 is first fixed before the annular frame 806 allows the brush filament 3 to be stored and bent, so as to avoid the phenomenon that the outer brush filament 3 has different lengths due to bending.

[0040] After the assembly is completed, water is pumped in the reverse direction through the pump body 10. Under the action of the pressure difference and the telescopic spring 1303, the positioning block 1402 is received in the hollow groove 1401, and the inner cylinder 1302 is received in the outer cylinder 1301. Then the annular frame 806 can be separated from the column body 4.

[0041] Reference Figure 6The bottom cover conveying mechanism 5 includes a first circular shell 502 fixedly arranged and a first strip shell 503 fixedly arranged on and connected to the first circular shell 502, a first turntable 504 is rotatably arranged inside the first circular shell 502 and a first motor is fixedly arranged for driving the first turntable 504 to rotate, wherein a plurality of bottom cover holes 501 are evenly formed on the first turntable 504; a first conveying belt 505 is arranged inside the first strip shell 503,

[0042] With this design, the bottom cover body 1 is conveyed to the inside of the bottom cover hole 501 by the first conveyor belt 505, and the first turntable 504 is driven to move by the first motor, so that the bottom cover body 1 in the bottom cover hole 501 on the first turntable 504 moves to the assembly station for assembly.

[0043] Reference Figure 7 The connecting pipe conveying mechanism 6 includes a second circular shell 602 fixedly arranged and a second strip shell 603 fixedly arranged on and connected to the second circular shell 602, a second rotating disk 604 is rotatably arranged inside the second circular shell 602 and a second motor is fixedly arranged to drive the second rotating disk 604 to rotate, wherein a plurality of connecting pipe holes 601 are evenly formed on the second rotating disk 604; a second conveying belt 605 is arranged inside the second strip shell 603;

[0044] In this design, the connecting pipe body 2 is conveyed to the inside of the connecting pipe hole 601 by the second conveyor belt 605, and then the second turntable 604 is driven to rotate by the second motor, so that the connecting pipe body 2 in the connecting pipe hole 601 on the second turntable 604 moves to the assembly station for assembly.

[0045] Depend on Figure 7 It is shown that the column conveying mechanism 7 includes a fixedly arranged third strip housing 702, and a third conveying belt 703 is arranged inside the third strip housing 702; a column hole 701 is formed at the end of the third strip housing 702, and a notch is formed on the third strip housing 702 for the brush filaments 3 assembled with the belt to pass through;

[0046] With such a design, the column body 4 can be transported to the assembly station via the third conveyor belt 703 .

[0047] Depend on Fig. 9 It is shown that an adjusting member 15 is arranged on the outer side of the third strip-shaped housing 702, and the adjusting member 15 comprises an adjusting motor 1501 fixedly arranged and an adjusting wheel 1502 fixedly arranged on the output shaft of the adjusting motor 1501; wherein an infrared beam switch 1503 is fixedly arranged inside the notch, and two notches are arranged, and the emitter and the receiver of the infrared beam switch 1503 are respectively located inside the two notches;

[0048] With such a design, when the column body 4 moves to the column hole 701, if the two side grooves 402 on the column body 4 are aligned with the grooves, the emitter and the receiver of the infrared beam switch 1503 can be connected. At this time, the adjusting motor 1501 does not work and does not need to be adjusted. If they are not aligned, the emitter and the receiver of the infrared beam switch 1503 cannot be connected, causing the signal to change, so that the adjusting motor 1501 drives the adjusting wheel 1502 to rotate, and the adjusting wheel 1502 drives the column body 4 to rotate through friction until the emitter and the receiver of the infrared beam switch 1503 can be connected. At this time, the brush filament 3 can be installed.

[0049] Reference Figure 8 A material discharge port is formed on both the first circular shell 502 and the second circular shell 602, and a material discharge member 9 is provided at the edge of the material discharge port on the first circular shell 502; the material discharge member 9 comprises a telescopic cylinder 901 and a baffle 902; wherein the telescopic cylinder 901 is fixedly arranged on the first circular shell 502, and the baffle 902 is fixedly arranged at the output end of the telescopic cylinder 901;

[0050] With this design, after the assembly is completed, the baffle 902 is driven to move by the telescopic cylinder 901, so that the baffle 902 no longer blocks the assembly. At this time, the assembled brush can fall under the action of gravity to complete the unloading operation.
