In this arrangement, the opening position of the driving slide groove 261 and the mounting positions of the driving sliding block 262 and the positioning plate 32 are determined.

[0025] Example 3: Based on example 2 and this embodiment, the difference is that: Figures 1 to 6 and Figure 10 As shown in the figure, the inner cavity of the moving plate 21 is provided with a moving slide groove 212 on the opposite side walls of the rectangular notch 211, the two moving slide grooves 212 are symmetrical to each other, the inner cavities of the two moving slide grooves 212 are slidably provided with a moving slide block 213, the two moving slide blocks 213 are symmetrical to each other, the opposite side wall of the two moving slide blocks 213 is provided with a plug-in block 215, and the opposite side walls of the plug-in block 215 are provided with an inclined surface 216.

In this configuration, the installation positions of the irregularly shaped slide rails 3 and the placement sliders 31 are determined.

[0028] like Figures 1 to 6 and Figure 8 As shown, a feed plate 15 is further provided between the middle baffle 11 and the rear baffle 112, with one end of the feed plate 15 located on the mounting plate 122. In this configuration, the installation position of the feed plate 15 is determined.

[0029] like Figures 1 to 6 and Figure 8 As shown, furthermore, the front baffle 1, the middle baffle 11, the rear baffle 112, and the bottom of the fixing plate 123 are all provided with multiple equally spaced support legs 117. In this configuration, the installation positions of the support legs 117 are determined.

[0030] The implementation principle of the automated assembly machine for handheld vacuum cleaner heads of the present invention is as follows: First, the operator places the mounting housing and cover of the handheld vacuum cleaner head onto the front transfer roller 115 and the rear transfer roller 116, respectively. After placement, the operation of the transfer rollers is controlled, so the front transfer roller 115 and the rear transfer roller 116 can respectively transport the placed handheld vacuum cleaner head mounting housing and cover. (The handheld vacuum cleaner head mounting housing is placed on the front roller, while the handheld vacuum cleaner head cover is placed on the rear transfer roller 116. The rear transfer roller 116 is initially set horizontally and then tilted upwards, thus ensuring that the handheld vacuum cleaner head cover can first move horizontally and then be lifted.)

[0031] When the handheld vacuum cleaner head cover plate is lifted and moved to a certain distance on the rear transmission roller 116, it can move horizontally. At this time, the handheld vacuum cleaner head cover plate can press the inclined surface opened on the blocking plate 27, so that the blocking plate 27 can rotate under the assistance of the mounting bearing 231 and the rotating rod 232 arranged on the connecting plate 23. When the blocking plate 27 rotates, the handheld vacuum cleaner head cover plate can continue to be transmitted under the assistance of the transmission roller, until it enters the other side of the blocking plate 27. At this time, the blocking plate 27 can reset under the assistance of the torsional spring 233, and the handheld vacuum cleaner head cover plate will be able to move obliquely downward under the assistance of the discharging plate 15; At this time, the staff controls the operation of the hydraulic cylinder 2, and the hydraulic cylinder 2 can push the moving plate 21 to move horizontally. When the moving plate 21 moves horizontally, it will drive the plug-in block 215 to move horizontally. At the same time, when the moving plate 21 moves horizontally, the inclined surface of the fitted wedge-shaped block 25 will lose the pressing force, so that the wedge-shaped block 25 can move horizontally under the assistance of the sliding groove 251, the sliding block 252 and the sliding reset spring 253. When the wedge-shaped block 25 moves horizontally, the other end of the inclined surface of the fixed block 242 fitted thereto will drive the connecting rod 24, the connecting plate 23 and the connecting rod 24 to move obliquely downward under the assistance of the inclined slide rail 22 and the mounting block 221, so that the blocking plate 27 always pushes the handheld vacuum cleaner head cover plate to move obliquely downward; At the same time, the connecting plate 23 moves and drives the placing rod 26 to move horizontally. When the placing rod 26 moves horizontally, it will push the positioning plate 32 to move obliquely downward and then horizontally under the assistance of the special-shaped slide rail 3 and the placing sliding block 31. Until the handheld vacuum cleaner head cover plate moves to the mounting plate 122. At this time, the moving plate 21 is fitted with the handheld vacuum cleaner head cover plate under the assistance of the hydraulic cylinder 2, so as to push the handheld vacuum cleaner head cover plate to move to the direction of the front transmission roller 115 (and the handheld vacuum cleaner head mounting shell is in contact with and blocked by the limiting turnover plate 12 under the assistance of the front transmission roller 115). At this time, the handheld vacuum cleaner head cover plate continues to move to the front transmission roller 115, and moves above the handheld vacuum cleaner head mounting shell (wherein the positioning plate 32 is located at the uppermost of the special-shaped slide rail 3 at this time, so as to ensure that the handheld vacuum cleaner head mounting shell can pass through the positioning plate 32 without being disturbed). The plug-in block 215 arranged in the moving plate 21 will move downward under the assistance of the reset spring 214, the moving sliding groove 212 and the moving sliding block 213, so that the moving plate 21 and the plug-in block 215 can push the handheld vacuum cleaner head cover plate, the handheld vacuum cleaner head mounting shell and the side plate 13 to be fitted (at the same time, the positioning plate 32 moves to one end of the special-shaped slide rail 3, and the positioning block 321 above it limits the handheld vacuum cleaner head mounting shell, so as to ensure that the handheld vacuum cleaner head cover plate and the mounting shell are aligned); When the handheld vacuum cleaner head cover plate and the mounting shell are aligned, the worker can press the handheld vacuum cleaner head cover plate onto the mounting shell through the existing hydraulic cylinder pressing or air pressure method, thereby realizing the assembly of the handheld vacuum cleaner head. When the assembly is completed, the limiting turnover plate 12 is opened at this time, thereby ensuring that the assembled handheld vacuum cleaner head cover plate and the mounting shell can be transported away (wherein the opening mode of the limiting turnover plate is the prior art).
