In the structure, the piston rods of the two push rods can move independently, and the clamping and the loosening of the corresponding steel sheets can be independently realized. Because the lead screw 412 is a positive lead screw and a negative lead screw, the third slide block 406 and the fourth slide block 411 move synchronously, and the speeds of the two blocks are the same, but the directions of the two blocks are opposite.
While the structure is specifically explained in the embodiment, the embodiment also provides a method for disassembling the boneless wiper based on the structure, which mainly comprises the following steps:
s1, inserting a central shaft buckle 505 of a wiper main body 500 into a positioning rod 304, and enabling the lower surface of the central shaft buckle 505 to be attached to the upper surface of a boss 302;

s4, the second sliding block 204 moves upwards firstly, the main shaft of the positioning motor 206 rotates, and the second sliding block 204 moves downwards again, so that the upper cutter 210 is positioned at the left side of the rubber strip 502, and the state is shown in FIG. 12;
then, the first sliding block 202 moves rightwards to drive the upper cutting knife 210 to move rightwards synchronously, so that the upper cutting knife 210 cuts off the upper part of the rubber strip 502 (namely, the part of the rubber strip 502 above the steel sheet), and the state is shown in fig. 13;
s5, the second electric push rod 410 drives the third clamping block 409 to retreat, but the left part of the steel sheet is still positioned in the clamping grooves of the third clamping block 409 and the fourth clamping block 408; then the third slider 406 and the fourth slider 411 move towards each other simultaneously and stop when approaching the central shaft buckle 505; the first clamp splice 404 is then moved forward to apply pressure to the right portion of the sheet;
the second sliding block 204 moves upward first, the first sliding block 202 moves leftward, the main shaft of the positioning motor 206 rotates, and the second sliding block 204 moves downward again, so that the middle buckle pushing block 211 is attached to the upper surface of the right part of the steel sheet, and the middle buckle pushing block 211 is located between the right middle buckle 506 and the first clamping block 404, which is shown in fig. 14;

s7, separating the central shaft buckle 505 from the hollow inserting shaft 509.
The state after completion of step S6 and step S7 is as shown in fig. 17.
The front windshield of the automobile is arc-shaped, the windscreen wiper is arc-shaped under the common condition for ensuring the jointing of the windscreen wiper and the front windshield, and the radian is greater than that of the front windshield, so that the windscreen wiper can be reliably jointed on the front windshield after being assembled. However, since the wiper is curved rather than linear in the free state, the steps S2, S3, S4 and S5 in the disassembling method provided by the present invention all make the electric push rod move for many times. The windscreen wiper in-service life who disassembles because of needs surpasss 1 year more, and the tip buckle all is difficult to directly disassemble with middle buckle, so this scheme has more innovation to the characteristics that tip buckle and middle buckle are difficult to disassemble to disassembling the method part, specifically:
in step S2, before the right end buckle is separated, the first electric push rod 405 clamps the right portions of the upper steel sheet 504 and the lower steel sheet 507 (i.e. applies a pressing force to the right portions of the two steel sheets), so that the tension of the right end buckle 508 by the right steel sheet can be greatly reduced, and the right end buckle 508 can be conveniently disassembled. The same applies to the principle of disassembling the left end buckle 501 in step S3.
After the two end snaps have been disassembled, the end snaps are unable to interfere with the movement of the middle snap. Before the middle buckle 506 on the right side and the middle buckle 503 on the left side are disassembled, the steel sheet close to the middle buckle 506 on the right side and the middle buckle 503 on the left side is also stressed, so that the tension of the steel sheet on the middle buckle can be greatly reduced, and the middle buckle 506 on the right side and the middle buckle 503 on the left side can be conveniently detached from the windscreen wiper through the middle buckle pushing block 211.
It should be noted that, because the wiper is in an arc-shaped free state rather than a linear free state, the invention also additionally states that the steel sheet is required to be ensured to be always positioned in the clamping groove when the clamping block moves back and forth in the disassembling method (if the retreating amplitude of the clamping block is too large, the steel sheet is separated from the clamping groove to be in an arc-shaped free state, and the subsequent purpose cannot be achieved).
After the structure and the method are adopted, the two end buckles and the two middle buckles of the wiper can be disassembled, and the adhesive tape I can be cut into two. After the rubber strip is divided into two parts, the interference of the upper part of the rubber strip is avoided when the steel sheet is manually disassembled, and the steel sheet disassembling machine is very convenient. And because the end part buckle and the middle buckle are mechanically disassembled, the disassembly process is very efficient, the risk that parts are possibly damaged in the manual disassembly process is avoided, and the yield is effectively improved.
The method for separating the hollow inserting shaft from the central shaft buckle is the prior art, and the scheme is not described herein again.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and features disclosed herein.
