For example, the rotary cylinder 23 can make the roller brush blank 91 rotate 90 degrees each time with the axis of the roller brush blank 91 as the axis.

[0060] In this embodiment, the V-shaped patch conveying mechanism 3 includes a front slide assembly 32 and a rear slide assembly 33 that are symmetrically arranged front and back. Both the front slide assembly 32 and the rear slide assembly 33 can move along the X-axis direction. The V-shaped receiving groove 31 is located in the front slide assembly 32 and the rear slide assembly 33, that is, the front slide assembly 32 and the rear slide assembly 33 each contain a V-shaped receiving groove 31, and the two V-shaped receiving grooves 31 are symmetrically arranged front and back. Along the X-axis direction, the roller brush clamping mechanism 2 is located between the front slide assembly 32 and the rear slide assembly 33. Figures 6 to 9 shown.

A front long strip lower notch is provided at the lower end of the front upper opening and closing plate 324, and a front long strip upper notch is provided at the upper end of the front lower opening and closing plate 325. When the front upper opening and closing plate 324 contacts the front lower opening and closing plate 325, the front long strip lower notch and the front long strip upper notch are combined into a V-shaped accommodating groove 31 on the front side.

The L-shaped rear slide plate advancing and retreating cylinder 338 moves the L-shaped rear slide plate 331 forward and backward along the X-axis direction. The L-shaped rear slide plate advancing and retreating cylinder 338 and the L-shaped front slide plate advancing and retreating cylinder 328 act synchronously, so that the L-shaped front slide plate 321 and the L-shaped rear slide plate 331 are moved closer to or away from each other.

[0076] Step 3, through the transverse driving mechanism (including the rodless cylinder), the V-shaped patch conveying mechanism 3 is moved 350 mm to the left as a whole, that is, the V-shaped patch conveying mechanism 3 is moved from the standby position to the working position. At this time, the V-shaped roller brush patch 92 in the front V-shaped receiving groove 31 is just located at the front side of the patch installation area on the front side of the roller brush blank 91, and the V-shaped roller brush patch 92 in the rear V-shaped receiving groove 31 is just located at the rear side of the patch installation area on the rear side of the roller brush blank 91.

[0077] Step 4, the L-shaped front slide plate 321 moves backward 10 mm, and the L-shaped rear slide plate 331 moves forward 10 mm, that is, the V-shaped roller brush patch 92 in the front V-shaped receiving groove 31 and the V-shaped roller brush patch 92 in the rear V-shaped receiving groove 31 both approach the roller brush blank 91, until the inner surfaces of the two V-shaped roller brush patches 92 are in partial contact with the outer surface of the roller brush blank 91.

[0078] Step 5. The front and rear two local pressing components 41 move toward each other by 20 mm simultaneously along the X-axis direction. The ejector pins 44 of the two local pressing components 41 press and connect the local V-shaped roller brush patch 92 with the roller brush blank 91, thereby achieving preliminary fixation of the V-shaped roller brush patch 92 and the roller brush blank 91.

[0079] Step 6, the front upper opening and closing plate 324 and the rear upper opening and closing plate 334 are both moved upward by 5 mm, and the front lower opening and closing plate 325 and the rear lower opening and closing plate 335 are both moved downward by 5 mm; the V-shaped roller brush patch 92 is separated from the V-shaped receiving groove 31.

[0080] Step 7: The L-shaped front slide plate 321 moves forward by 10 mm, and the L-shaped rear slide plate 331 moves backward by 10 mm, thereby separating from the roller brush blank 91.

[0081] Step 8: The V-shaped patch conveying mechanism 3 is moved rightward as a whole by 350 mm through the transverse driving mechanism, that is, the V-shaped patch conveying mechanism 3 returns from the working position to the standby position.

[0082] Step 9, the front and rear two ring pressing components 51 move toward each other along the X-axis direction at the same time, and the annular pressing block 54 matches and presses the V-shaped roller brush patch 92 in the patch installation area of ​​the roller brush blank 91, and maintains it for 20 seconds. The time can be set, and the inner surface of the V-shaped roller brush patch 92 is completely bonded to the roller brush blank 91.

[0083] Step 10, the front and rear two local pressing components 41 move 20 mm away from each other along the X-axis direction at the same time, and the front and rear two ring pressing components 51 move away from each other along the X-axis direction at the same time, thereby completing the fixing of the two V-shaped roller brush patches 92 on the outer surface of the roller brush blank 91.

[0084] Repeat steps 1 to 10 in sequence, and the other two V-shaped roller brush patches 92 can be fixedly mounted on the outer surface of the roller brush blank 91. The side unfolding structure of the installed vacuum cleaner roller brush is shown in FIG. Fig. 20 The roller brush of the vacuum cleaner is a cylindrical structure. Fig. 20 It is a schematic diagram cut and unfolded along a generatrix of the roller brush of the vacuum cleaner.

[0085] Among them, the V-shaped roller brush patch 92 and the roller brush blank 91 must be precisely aligned when they are fitted, and the edge of the V-shaped roller brush patch 92 and the edge of the corresponding area on the roller brush blank 91 should be guaranteed to be within the allowable error of plus or minus 0.2 mm. In order to accurately align the V-shaped roller brush patch 92 and the roller brush blank 91 during the fitting process, the V-shaped roller brush patch 92 is pre-placed in the V-shaped receiving groove 31. In order to prevent displacement during the fitting process, the V-shaped roller brush patch 92 is fixed to the roller brush blank 91 by the needle tip of the ejector pin 44 of the local pressing component 41, and the ring pressing component 51 causes it to move during the pressing process. In order to ensure that the patch is completely fitted and tight, the annular pressing block 54 is produced by 3D printing using reverse engineering technology, so that the V-shaped roller brush patch 92 can be completely fitted to the roller brush blank 91.
