The sliding clamping mechanism is arranged on one side of the working table top 10 and comprises a slide rail 20 and a plurality of clamping assemblies 30 arranged on the slide rail 20, each clamping assembly 30 can slide on the slide rail 20 to adjust the distance between the clamping assemblies, and each clamping assembly 30 is provided with an independent electric control clamping mechanism for clamping one side of a positioned upper material sheet 1 on the upper surface of a lower material sheet 2.

In an alternative embodiment, the clamping assembly 30 is provided with a sliding sleeve 31 penetrating through the sliding rail 20, a locking mechanism 32 is provided on the sliding sleeve 31, and the clamping assembly 30 is locked on the sliding rail 20 by the locking mechanism 32. Preferably, the locking mechanism 32 is a locking screw.

In an alternative embodiment, the electrically controlled clamping mechanism comprises a clamping sheet 37, a lifting mechanism and a control switch 34; the middle of the clamping piece 37 is hinged to the sliding sleeve piece 31, the rear end of the clamping piece 37 is connected with the lifting mechanism, the lifting mechanism jacks up the rear end of the clamping piece 37 to enable the front end of the clamping piece 37 to descend so as to compress the lower material sheet 2 on the upper surface of the upper material sheet 1, and the control switch 34 is connected with the lifting mechanism. The front end depression of the holding piece 37 is similar to the principle of the seesaw movement.

In another alternative embodiment, the electrically controlled clamping mechanism comprises a clamping sheet 37, a lifting mechanism and a control switch 34; the holding piece 37 is fixedly installed on the lifting mechanism, the lifting mechanism is connected with the control switch 34, the lifting mechanism drives the holding piece 37 to descend so as to press the lower material sheet 2 on the upper surface of the upper material sheet 1, and the control switch 34 is connected with the lifting mechanism, as shown in fig. 5-6.

In the above two embodiments, the lifting mechanism is a pneumatic lifting mechanism installed on the sliding sleeve 31, and the pneumatic lifting mechanism is connected to an external air source through the air source port 33. Of course, the lifting mechanism may also adopt other forms, such as a motor or a lead screw pair, which are not described herein.

In an alternative embodiment, an adjusting block 35 is disposed on one side of the sliding sleeve 31 close to the work table 10, and the clamping sheet 37 is slidably mounted on the adjusting block 35 through an adjusting knob 36 to adjust the distance between the clamping sheet 37 and the work table 10.

In an alternative embodiment, the slide rail 20 comprises two slide bars 21, and each slide set 31 is disposed through both of the slide bars 21.

In an optional embodiment, the spreading and positioning device further comprises a transfer device 40, the transfer device 40 is composed of a multi-axis moving mechanism 41 and a multi-section pressing mechanism mounted on the multi-axis moving mechanism 41, the multi-section pressing mechanism comprises a supporting cross plate 42, a plurality of independently controlled telescopic assemblies 43 are arranged on the supporting cross plate 42, and a horizontal pressing plate 44 is mounted at the bottom of each telescopic assembly 43. Fig. 9 is a structural diagram of a multi-section pressing mechanism in an embodiment, wherein 5 telescopic assemblies 43 are arranged on a supporting transverse plate 42, and a horizontal pressing plate 44 is installed at the bottom of each telescopic assembly. The 5 retraction assemblies 43 are controlled independently of each other. The telescopic assembly 43 is a telescopic motor or a cylinder.

After the clamping assembly 30 clamps one side of the positioned upper material sheet 1 on the upper surface of the lower material sheet 2, the first telescopic assembly 43-1 drives the pressing plate 44 to press the upper surface of the flat part of the upper material sheet 1 first, and then the second telescopic assembly 43-2 drives the bottom pressing plate 44 to press the upper surface of the arched part of the upper material sheet 1. The benefit of using segmented compaction is that: since the upper panel is partially arched, the arched state needs to be maintained before sewing, and if the upper panel is directly pressed down all at once, the arched part of the upper panel can be displaced, thereby affecting the quality of the collar after sewing. Based on the background, the invention firstly controls the first telescopic assembly 43-1 to drive the pressing plate 44 to press the upper surface of the flat part of the upper material sheet 1, at the moment, the arching part is not pressed, and both sides of each arching part are pressed, thereby realizing the limiting effect of the arching part; then the second telescopic assembly 43-2 is pressed down to ensure that the arched part can not be displaced and the collar quality is ensured.

In an optional embodiment, the paving material positioning device provided by the invention further comprises: a visual recognition system, which is connected to the transfer device 40. The vision recognition system is used to recognize the position of the crown 1a of the upper material sheet 1 and to control the respective telescopic assemblies 43 to press against the upper material sheet 1 in turn. Due to the fact that the collar arch positions of collars of different specifications are different, the visual recognition system can automatically achieve the effect that the first telescopic assembly is firstly pressed on the upper surface of the flat part of the upper material sheet 1, and then the second telescopic assembly is pressed on the arch part, and automatic segmented pressing is achieved.

The operation process of the invention is as follows:

1) a lower material sheet 2 is placed on a table top 10 and an upper material sheet 2 is placed on the upper surface of the lower material sheet 2, the upper material sheet 2 being provided with a local camber 1a, as shown in fig. 2.

2) The locking mechanism 32 is released to enable each clamping assembly 30 to be slidable on the sliding rod 21, after the clamping assemblies 30 are adjusted to the proper positions, the control switch 34 is pressed, and the lifting mechanism drives the clamping piece 37 to descend to clamp one side of the positioned upper material sheet 1 on the upper surface of the lower material sheet 2. After the repetition, one side of the upper web 1 is held by the plurality of holding members 30 in a state shown in fig. 7.

3) The multi-axis moving mechanism 41 drives the multi-section pressing mechanism to move above the material sheet, as shown in fig. 7; then the first telescopic assembly 43-1 of the multi-section pressing mechanism drives the pressing plate 44 to press the upper surface of the flat part of the upper material sheet 1 first, as shown in fig. 11; the second stretching assembly 43-2 then brings the bottom pressing plate 44 to press against the upper surface of the bulged portion of the upper sheet 1 as shown in fig. 12, whereby the upper sheet is completely pressed against the lower sheet.

4) Finally, the multi-axis moving mechanism 41 drives the multi-section pressing mechanism pressed on the paving material to move and transfers the upper and lower material sheets to the next station by means of sliding friction for sewing.
