[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] The components of the wiper 1 to be assembled in the present invention include a deflector 11, an interface shell 12, an elastic steel sheet 13, a right end cover 14, a rubber strip 15 and a left end cover 16. The wiper 1 is assembled from the above parts.

[0040] The interface shell 12 is a shell structure with an opening on the top surface. The interface shell 12 includes a main body 121 and a clamp 122 arranged at both ends of the main body 121 and connected to the main body 121. The end faces of the clamp 122 are both provided with openings. The inner cavity shape of the clamp 122 is the same as the shape of the lower half of the guide plate 11. The main body 121 is provided with ribs for axial limiting. The guide plate 11 is pressed into the interface shell 12 from top to bottom, so that the middle and lower half of the guide plate 11 in the thickness direction is inserted into the interface shell 12, and the interface shell 12 is installed in the middle position of the guide plate 11 in the length direction; a receiving cavity 111 is provided in the middle of the guide plate 11 in the thickness direction, and openings are provided at both ends of the receiving cavity 111. The elastic steel sheet 13 can be opened from one of the openings of the receiving cavity 111. The right end cover 14 is provided with a first clamping cavity 142, and the first clamping cavity 142 can be clamped on the right end of the guide plate 11 to prevent the elastic steel sheet 13 from falling from the right end opening of the accommodating cavity 111. The upper part of the guide plate 11 is provided with a clamping cavity 112, and the clamping cavity 112 is provided with openings at both ends. The rubber strip 15 is clamped into one of the openings of the clamping cavity 112. The top of the clamping cavity 112 is provided with an opening, and most of the rubber strip 15 can be exposed through the opening. Finally, the left end cover 16 can be clamped on the left end of the guide plate 11 (the left end cover 16 is provided with a second clamping cavity 162, and the second clamping cavity 162 is clamped on the left end of the guide plate 11) to prevent the elastic steel sheet 13 from falling from the left end opening of the accommodating cavity 111. A first plug-in cavity 141 and a second plug-in cavity 161 are respectively provided on the top of the right end cover 14 and the left end cover 16. An opening is provided at one end of the first plug-in cavity 141 and the second plug-in cavity 161. Both ends of the rubber strip 15 extend out of the two ends of the guide plate 11 respectively, and the extended parts enter from the openings of the first plug-in cavity 141 and the second plug-in cavity 161 respectively, so that both ends of the rubber strip 15 are simultaneously clamped by the left end cover 16 and the right end cover 14.

[0041] The left end cover 16 is simultaneously clamped with the left end of the guide plate 11 and the left end of the rubber strip 15 , and the right end cover 14 is simultaneously clamped with the right end of the guide plate 11 and the right end of the rubber strip 15 , thereby improving the overall connection stability of the wiper 1 .

[0042] The present invention provides an automated step-by-step assembly system for automobile wipers, comprising a workbench 2 and a first assembly system 3, a second assembly system 4, a third assembly system 5, a fourth assembly system 6 and a step-by-step transfer device 7 which are sequentially arranged along the X-axis direction (specifically along the length direction of the workbench 2 in the present invention).

[0043] The guide plate 11 and the interface shell 12 are loaded on two sides of the first assembly system 3 respectively, and the guide plate 11 and the interface shell 12 are assembled together at the assembly station to form a first assembly body 50, and the first assembly body 50 is transferred to the assembly station of the second assembly system 4, and the elastic steel sheet 13 and the right end cover 14 are also loaded on two sides of the second assembly system 4 respectively, and the loaded elastic steel sheet 13 and the right end cover 14 are jointly added to the first assembly body 50 to form a second assembly body 60, and the second assembly body 60 is transferred to the assembly station of the third assembly system 5, and the rubber strip 15 is loaded on one side of the third assembly system 5, and the rubber strip 15 is added to the second assembly body 60 to form a third assembly body 70, and the third assembly body 70 is transferred to the assembly station of the fourth assembly system 6, and the left end cover 16 is loaded on one side of the fourth assembly system 6, and the left end cover 16 is added to the third assembly body 70 to form a product.

[0044] In order to ensure that the horizontal space occupied by the whole machine is not too large and save space, the device for transferring the assembly body adopts a stepping transfer device 7. The stepping transfer device 7 includes a horizontal fixed rod 71, and a first clamping claw 72, a second clamping claw 73, a third clamping claw 74 and a fourth clamping claw 75 are arranged at intervals below the fixed rod 71. The fixed rod 71 is connected to the slider of the longitudinal electric slide rail 76, and the longitudinal electric slide rail 76 is fixed to the slider of the transverse electric slide rail 77, so that the fixed rod 71 can move along the two dimensions of the X axis and the Z axis.

[0045] The stepping conveyor 7 can be raised and lowered by the longitudinal electric slide rail 76 and horizontally displaced by the transverse electric slide rail 77. When the assembly is not displaced, the stepping conveyor 7 is at a higher position, so that each clamping jaw is separated from each assembly system by a larger distance. When the assembly needs to be displaced, the stepping conveyor 7 is lowered and then moved horizontally. This saves space compared to installing a conveyor on each of two adjacent assembly system brackets.

[0046] The distance between two adjacent clamps is S1, and the distance between two adjacent assembly system assembly stations is S2, S1=S2. In the initial state, the positions of the first clamp 72, the second clamp 73, the third clamp 74 and the fourth clamp 75 correspond to the assembly stations of the first assembly system 3, the second assembly system 4, the third assembly system 5 and the fourth assembly system 6, respectively. Each clamp can clamp the corresponding assembly. The stepping transfer device 7 steps a stroke equal to S1 each time, and moves the clamped different assembly to the assembly station of the next assembly system step by step, so that all assemblies can be transferred to different assembly processes in turn for assembly and blanking.

[0047] The first assembly system 3 includes a first vibration plate 31, a loading device 32, a transport and pressing device 33 and a first assembly station 34. The first vibration plate 31 and the loading device 32 are respectively arranged on two sides of the workbench 2. The first vibration plate 31 loads the interface shell 12 onto the first assembly station 34. The loading device 32 loads the guide plate 11 to the initial position of the transport and pressing device 33. The transport and pressing device 33 can move the guide plate 11 to the interface shell 12 on the first assembly station 34, and press the guide plate 11 down to the interface shell 12. The first vibration plate is a prior art product, and only the screening track inside it is customized according to the shape of the interface shell 12. The loading device 32 includes a chain belt and an endless belt. At least two parallel chain belts are arranged on the outer surface of the endless belt. The chain belt is composed of chain links. A card slot is arranged on the upper surface of each chain link, so that a guide plate 11 is simultaneously carded on two chain links corresponding to each other on the two chain belts.

[0048] The transport and pressing device 33 comprises a horizontal cylinder 331, a lifting cylinder 332, an automatic clamp 333 and a pressing block 334. The body of the lifting cylinder 332 is fixed on the telescopic rod of the horizontal cylinder 331, the automatic clamp 333 is fixed on the telescopic rod of the lifting cylinder 332, and the pressing block 334 is fixed on the body of the automatic clamp 333.

The automatic clamp 333 is used to clamp the guide plate 11, and the pressing block 334 is used to press the guide plate 11 down into the card slot of the interface shell 12.

[0049] The second assembly system 4 includes a vertical warehouse in place 41, a first transfer device 42, a shaping device 43, a second transfer device 44, a second assembly station 45, a second vibration plate 46, a third transfer device 47 and a right end cover feeding table 48, all of which are arranged on the workbench 2. The vertical warehouse in place 41 is used to place a plurality of elastic steel sheets 13. The second assembly station 45 is clamped with a first assembly body 50. The first transfer device 42 can transfer the elastic steel sheets 13 on the vertical warehouse in place 41 to the shaping device 4 one by one at a time. 3, the shaping device 43 shapes the elastic steel sheet 13 bent in a natural state into a straight state and maintains it, the second transfer device 44 can push the elastic steel sheet 13 on the shaping device 43 into the guide plate 11 on the first assembly 50, and the second vibration plate 46 feeds the right end cover 14 to the right end cover feeding table 48, and the third transfer device 47 pushes the right end cover 14 on the right end cover feeding table 48 one by one and sleeves it on the right end of the guide plate 11, finally forming the second assembly 60.

[0050] The third assembly system 5 includes a loading tray 51, an intermittent shifting device 52, a pumping mechanical claw 53 and a third assembly station 54. The third assembly station 54 is clamped with a second assembly body 60. A plurality of rubber strips 15 are placed side by side in the loading tray 51. The loading tray 51 is fixed on the intermittent shifting device 52. The intermittent shifting device 52 drives the loading tray 51 to shift in steps. The moving direction of the intermittent shifting device 52 is perpendicular to the length direction of the rubber strips 15 in the loading tray 51. The pumping mechanical claw 53 transfers the corresponding rubber strips 15 in the loading tray 51 to the second assembly body 60, and is clamped on the second assembly body 60 at the same time to form a third assembly body 70.

[0051] The fourth assembly system 6 includes a third vibration plate 61, a left end cover feeding table 62, a fourth transfer device 63 and a fourth assembly station 64. The third vibration plate 61 loads the left end cover 16 onto the left end cover feeding table 62. The fourth assembly station 64 is clamped with a third assembly body 70. The fourth transfer device 63 pushes the left end cover 16 on the left end cover feeding table 62 one by one and sleeves it on the left end of the guide plate 11 of the third assembly body 70 to form a final product.

[0052] The present invention also includes a detection device 8. The workbench 2 is provided with a blanking opening 21, and an inclined blanking plate 9 is provided under the workbench 2. The inclined blanking plate 9 covers the entire blanking opening 21. The detection device 8 includes a camera 81, an illuminator 82, a fixed bracket 83 and a sliding device 84. The sliding device 84 is arranged side by side with the fourth assembly station 64, and the length extension directions of the two are parallel. The bottom of the fixed bracket 83 is fixed on the actuator of the sliding device 84, and the top of the fixed bracket 83 is fixed with the illuminator 82 and the camera 81. The function of the detection device 8 is to detect the rubber strip 15 of the assembled product and detect whether there are convex defects on the rubber strip 15. During the detection, the fourth assembly station 64 continues to clamp the assembled product, and the actuator of the sliding device 84 drives the fixed bracket 83 to move, that is, drives the camera 81 and the illuminator 82 to move, and moves along the length direction of the product to shoot and detect the rubber strip 15. If it is detected that the rubber strip 15 does not meet the quality requirements, the rubber strip 15 will be moved to the blanking opening 21, and the products that do not meet the quality requirements will fall out from the blanking opening 21, and the unqualified products will slide out along the inclined blanking plate 9, and finally the products that do not meet the quality requirements will be screened out.

[0053] In order to timely sort and collect the assembled products and prevent the products from being scratched by stacking together, the present invention also includes a packing mechanism 10, which includes a box body positioning machine 101, a partition stacking machine 102 and a packing and shifting gripper 103. The box body positioning machine 101 positions the box body 30, and the partition stacking machine 102 stacks a plurality of partitions 40. The packing and shifting gripper 103 can clamp the assembled products and transfer them to the box body 30, so as to preliminarily pack and collect the products.

[0054] The packing shifting gripper 103 can also clamp the partition 40 on the partition stacker 102 to the upper surface of the product in the box body 30, so that there is a partition 40 between the two adjacent layers of products. The function of the partition 40 is also to prevent the upper layer product from touching the lower layer product during packing and causing scratches to the product.

[0055] The present invention also includes a flip structure 20, which is arranged between the fourth assembly system 6 and the box positioning machine 101. The stepping transfer device 7 can transfer the products assembled on the fourth assembly system 6 to the flip structure 20. The flip structure 20 clamps the product and flips the product 90 degrees so that the product lies on its side. Lying on its side is more conducive to the product being stably placed in the box 30. If the curved surface or concave surface is placed relative to the box 30, the product will fall down, which is not conducive to orderly placement. The box shifting gripper 103 is used to clamp and transfer the flipped product from the flip structure 20 to the box 30 for boxing.

[0056] The packing shifting gripper 103 includes a vacuum negative pressure suction cup head 103a, a packing clamping claw head 103b, a rotary cylinder 103c and a fixed plate 103d. The fixed plate 103d is fixed on the rotating shaft of the rotary cylinder 103c. One end of the fixed plate 103d fixes the vacuum negative pressure suction cup head 103a, and the other end fixes the packing clamping claw head 103b. When the product needs to be packed, the end of the fixed plate 103d that fixes the packing clamping claw head 103b is driven by the rotary cylinder 103c to rotate to a vertical downward state, and the packing clamping claw head 103b clamps and transfers the product flipped on the flip structure 20 to the box body 30. When a layer of products is loaded in the box 30, the fixed plate 103d rotates 180° again, and the end of the fixed plate 103d fixing the vacuum negative pressure suction cup head 103a faces downward, and the vacuum negative pressure suction cup head 103a absorbs a partition 40 and places it above the products in the box 30. Then the fixed plate 103d rotates 180° again, and the packing claw head 103b is driven downward again to continue the product packing work. The vacuum negative pressure suction cup head 103a and the packing claw head 103b always work downward alternately in a cycle.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
