Examples

As shown in fig. 1 and 2, the present embodiment provides an automatic bone assembling machine 100 for a wiper blade. The fastener is mainly used for assembling the fastener and the middle bone.

The automatic assembly machine 100 for the middle bones of the windshield wiper comprises a body. The body includes a transport mechanism 110, a hold down mechanism 150, and three pick-up grippers. The conveying mechanism 110 is used for conveying a workpiece (mainly a middle bone and a buckle in the embodiment) to a designated position. The compressing mechanism 150 is a device commonly used in the art and can completely assemble the buckle and the middle bone together. The picking and clamping mechanism picks the workpiece to a specified position.

Specifically, the conveying mechanism 110 is provided with a first station 111, a second station 112, a third station 113, and a fourth station 114 in this order. The three pickup clamping mechanisms correspond to the first station 111, the second station 112, and the fourth station 114, respectively. In the present embodiment, for convenience of description, the three pickup gripping mechanisms are the first pickup gripping mechanism 121, the second pickup gripping mechanism 122, and the third pickup gripping mechanism 123, respectively. That is, the first pick-up gripping mechanism 121 corresponds to the first station 111. The second pick-up gripper mechanism 122 corresponds to the second station 112. The third pick-up gripper mechanism 123 corresponds to the fourth station 114. The pressing mechanism 150 corresponds to the third station 113. It should be noted that "corresponding" here is understood to mean that, for example, the first picking jig 121 is disposed above the first station 111.

In this embodiment, the conveying mechanism 110 is not limited and may be a structure of a conveyor belt. At this time, the first station 111, the second station 112, the third station 113 and the fourth station 114 are sequentially arranged along the moving direction of the conveyor belt, generally along the length direction of the conveyor belt. Further, in a preferred mode of the present embodiment. The transport mechanism 110 includes a rotary disk 115 and a drive motor that drives the rotary disk 115 to rotate. The first station 111, the second station 112, the third station 113, and the fourth station 114 are sequentially disposed around the rotating disk 115. At this time, the workpiece can be transferred to the designated position only by rotating the rotary disk 115.

It should be noted that, in this embodiment, the workpiece is always located at one station. The first station 111, the second station 112, the third station 113, and the fourth station 114 simply express different positions on the transfer mechanism 110 in order to describe the positions of the three pick-up gripping mechanisms and the pressing mechanism 150.

Preferably, the first station 111, the second station 112, the third station 113, and the fourth station 114 are uniformly provided around the circumference of the rotary disk 115. That is, the first picking gripper 121, the second picking gripper 122, the pressing mechanism 140, and the third picking gripper 123 are uniformly provided around the circumference of the rotating disk 115. It can be understood that the angle between two adjacent stations is 90 °, and the rotating disc 115 only needs to rotate 90 ° to reach the next station position.

Further, the first station 111, the second station 112, the third station 113 and the fourth station 114 are all close to the edge of the rotating disc 115, so that other mechanisms can work conveniently, and the working efficiency is improved.

In this embodiment, the pick-up gripping mechanism includes a robot 143 and a moving assembly 140 connected to each other, and the moving assembly 140 moves the robot 143.

Further, the moving assembly 140 includes a first moving member 141 disposed in a vertical direction, and the first moving member 141 is connected to the robot 143. That is, the first mover 141 can move the robot 143 up and down.

Further, the moving assembly 140 includes a second moving member 142 disposed in the transverse direction, and the second moving member 142 is connected to the first moving member 141. That is, the second moving member 142 can drive the first moving member 141 and the robot 143 to move back and forth.

In the present embodiment, the specific structures of the first moving member 141 and the second moving member 142 are not limited, and all the structures commonly used in the prior art are adopted. The following modes can be realized: first, the first moving member 141 and the second moving member 142 are both lead screws. The first moving member 141 is a first lead screw, a first nut of the first lead screw is connected to the manipulator 143, and a second nut of the second lead screw is connected to the first lead screw. Second, the first moving member 141 and the second moving member 142 are both in a timing belt structure. Third, the first moving member 141 and the second moving member 142 are both of a cylinder structure.

In light of the above, the first moving member 141 and the second moving member 142 can drive the robot 143 to move up and down and back and forth, so that the workpiece can be picked up conveniently.

Further, in a preferred embodiment, the body further includes a position sensor for detecting the position of the workpiece, and the position sensor is disposed on the conveying mechanism 110. The position sensor detects whether the workpiece is located at a specified position.

The embodiment further provides an automatic assembly method for a middle rib of a windshield wiper, which adopts the automatic assembly machine 100 for assembly, and comprises the following steps:

s1: the clip is clamped to the first station 111 with a first pick-up clamp mechanism 121;

s2: after the buckle is conveyed to the second station 112 by the conveying mechanism 110, the middle bone is placed on the buckle by the second picking and clamping mechanism 122;

s3: after the conveying mechanism 110 conveys the buckle and the middle bone to the third station 113, the buckle and the middle bone are completely assembled together by the pressing mechanism 150;

s4: after the transfer mechanism 110 transfers the fully assembled clasp and middle bone to the fourth station 114, it is gripped by the third pick-and-hold mechanism 123.

Further, in an embodiment of the present invention, the position sensor is used to detect whether the buckle or the middle bone is at the designated station. The following will specifically explain the structure of the rotating disk 115: the gripping of the clasp is completed at the first station 111, i.e. the clasp is gripped from a designated position onto the first station 111 of the rotating disc 115. When the position sensor detects that the buckle is placed correctly, the rotating disc 115 rotates by 90 degrees, and the accurate position of the process is completed by the motor and the position sensor together. The rotating disc 115 rotates the work station for placing the buckle to the second work station 112, and the position sensor detects the buckle without error, and then clamps the middle bone and places the middle bone above the buckle, and then rotates to the third work station 113. Since only a part of the middle bone and the buckle at the second station 112 are assembled together and are not completely assembled, the rotating disc 115 rotates by 90 degrees to the third station 113, and the middle bone and the buckle are pressed to be completely matched after the position sensor detects that the workpiece is placed correctly. Finally, the fourth station 114 is reached, and the assembled middle bone clamps with the buckles are clamped to a specific position. It should be noted that, in the operation process, if it is detected that the workpiece is not placed at the station or the placed workpiece is wrong, the station will not operate until the station corresponding to the detected correct workpiece will not operate.

It should be noted that the working principle of the automatic wiper center assembly machine 100 in this embodiment refers to the above automatic wiper center assembly method, and details are not described here.

In summary, the automatic assembly machine 100 for the middle rib of the windshield wiper and the automatic assembly method for the middle rib of the windshield wiper provided by the embodiment are all automatic without manual work in the whole operation, so that the working efficiency is greatly improved, and the assembly quality of workpieces can be ensured.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
