The details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0026] Please see attached Figure 1 , 2As shown in Figure 5, an automatic assembly device for fisheye pin cylinders includes a jig 1 for placing fisheye pin strips, a pulling mechanism 5 for driving the fisheye pin strips to be transmitted on the jig 1, a vibration plate 2, a press-fitting assembly 4, and a feeding assembly 3. The vibration plate 2, the press-fitting assembly 4, and the feeding assembly 3 are all placed on one side of the jig 1. A cylinder 13 is placed in the vibration plate 2. The cylinder 13 is directly vibrated and transported to the feeding assembly 3 by the vibration plate 2. The vibration plate 2 can output one or two cylinders 13 at a time. According to the operability of the equipment, in this embodiment, preferably, the vibration plate 2 can output two cylinders 13 in one direct vibration, and the two cylinders 13 are arranged in parallel. The fixture 1 is provided with a press-fitting hole 6 on one side of the fisheye pin connection end, and the position of the press-fitting hole 6 is the assembly station of the fisheye pin and the cylinder 13. The feeding assembly 3 includes a movable block 31 and a driving mechanism for driving the movable block 31 to move back and forth along the edge of the fixture 1. The movable block 31 is provided with a plurality of grooves 32 for placing the cylinder 13. The number of cylinders 13 output at one time in the vibration disk 2, the number of grooves 32 can be set to 1, 2 or 4. Preferably, the number of grooves 32 in the present embodiment can be 4; specifically, the movable block 31 moves to the output end of the direct vibration of the vibration disk 2 under the action of the driving mechanism and makes the grooves 32 face the output port, firstly aligns the two grooves 32 with the two output ports at the output end of the vibration disk 2 for receiving the two cylinders 13, and then moves the movable block 31 to make the other two grooves 32 align with the two output ports at the output end of the vibration disk 2 again, so that the cylinder 13 just falls into the groove 32 one by one, thereby completing the loading of the cylinder 13 in the groove 32, and then transports the cylinder 13 in the groove 32 to the position of the press-fitting hole 6 through the driving mechanism of the loading component 3 and makes the cylinder 13 correspond to the connecting end of the fisheye pin one by one, and then the press-fitting component 4 faces the position of the press-fitting hole 6 and presses the cylinder 13 on the press-fitting hole 6 onto the connecting end of the fisheye pin, completing the assembly of the fisheye terminal and the cylinder 13.

[0027] In the above embodiment, preferably, the press-fitting component 4 has a faster speed in assembling the fisheye terminal and the cylinder 13. In order to improve the efficiency of the loading component 3, two vibration disks 2 and two movable blocks 31 can be provided. The two vibration disks 2 are respectively placed on both sides of the press-fitting component 4. The two vibration disks 2 and the two movable blocks 31 cooperate in loading the cylinder 13 in turn to improve work efficiency.

[0028] Please participate in the attached Figure 2 -Attached Figure 4As shown, the driving mechanism includes a linear module 34 and an assembly block 33 fixed on a slider of the linear module 34. The linear module 34 is placed below the jig 1 and arranged along the length direction of the jig 1. A mounting groove (not shown in the accompanying drawings) is provided in the assembly block 33. The linear module 34 drives the assembly block 33 and the movable block 31 on the assembly block 33 to move back and forth between the output end of the vibration plate 2 and the press-fitting hole 6. The movable block 31 is movably placed in the installation groove and the two ends of the movable block 31 extend out of the installation groove. The movable block 31 can move up and down in the installation groove, and the top of the movable block 31 cooperates with the press-fitting hole 6.

[0029] As attached Figure 4 As shown, a lifting cylinder 7 is provided below the press-fitting hole 6, and the lifting cylinder 7 is used to push the movable block 31 moved to the bottom of the press-fitting hole 6 upward until the cylinder 13 in the groove 32 corresponds one-to-one with the connection end of the fisheye pin; specifically, when the linear module 1 34 drives the movable block 31 to move to the bottom of the press-fitting hole 6 and stops moving, at this time, the output end of the lifting cylinder 7 moves upward and then abuts against the lower surface of the movable block 31 and drives the movable block 31 to move upward together until the surface of the movable block 31 is flush with the surface of the jig 1 where the fisheye pin is placed, and at the same time, the cylinder 13 in the groove 32 corresponds one-to-one to the connection of the fisheye pin.

[0030] As attached Figure 4 and attached Figure 5 As shown, the press-fitting assembly 4 includes a horizontally arranged propulsion cylinder 41 and a top block 42 connected to the output end of the propulsion cylinder 41, and a plurality of push rods 43 are provided at one end of the top block 42 facing the fixture 1, and the number of the push rods 43 corresponds to the number of the grooves 32 one by one; when the movable block 31 moves to make the cylinder 13 correspond to the fisheye pin one by one, the propulsion cylinder 41 drives the push block 42 and the push rod 43 on the top block 42 to move toward the cylinder 13 until the cylinder 13 is assembled to the connecting end of the fisheye pin, and the assembly of four cylinders 13 is completed at one time. After the assembly is completed, the pulling mechanism 5 pulls the fisheye terminal to move a step distance so that the unassembled fisheye pin is aligned with the press-fitting hole 6. Similarly, the distance between the four fisheye pins is one moving step distance.

[0031] In the above embodiment, preferably, the output end of the vibration disk 2 is provided with an optical fiber sensor 8 for detecting whether the cylinder 13 is discharged smoothly. If it is detected that there is no cylinder 13 at the output end, it means that there may be blockage or lack of material in the direct vibration of the vibration disk 2, and the staff is reminded to check in time. The downstream end of the press-fitting hole 6 is also provided with an optical fiber sensor 9 for detecting whether the cylinder 13 is pressed into place.

[0032] In the above embodiment, preferably, in order to prevent the fisheye pin strip from bending sideways during press-fitting, a pressure rod 10 for pressing the strip during press-fitting is provided above the jig 1. The pressure rod 10 is driven by a driving motor. When the fisheye terminal is aligned with the press-fitting hole 6 by moving a step, the driving motor drives the upper pressure rod 10 to move downward until the bottom end of the pressure rod 10 is pressed against the fisheye terminal strip.

[0033] Please see attached Figure 6 and attached Figure 7 As shown, the pulling mechanism 5 includes a linear module 2 51 placed below the jig 1, and a pulling cylinder 52 and a clamping plate 1 53 fixed on the slider of the linear module 2 51. The pulling cylinder 52 is fixed with a clamping plate 2 54 placed above the jig 1 and the clamping plate 1 53. The clamping plate 1 53 passes through the jig 1 and cooperates with the clamping plate 1 53 to clamp the fisheye pin strip. The downstream end of the pulling mechanism 5 is also provided with a clamping cylinder 55 fixed on the jig 1. The output end of the clamping cylinder 55 is fixed with a pressing block (not shown in the figure) for clamping the fisheye pin strip. ; Specifically, the clamping cylinder 55 drives the second clamp plate 54 to move downward and the clamp plate 1 53 cooperates to clamp the fisheye pin material strip, and then the linear module 2 51 drives the first clamp plate 53, the second clamp plate 54 and the fisheye pin material strip as a whole to move forward a step, and then the clamping cylinder 55 drives the second clamp plate 54 to move upward, and the linear module 2 51 drives the first clamp plate 53 and the second clamp plate 54 to move back to the initial position. During this process, in order to prevent the first clamp plate 53 and the second clamp plate 54 from driving the fisheye pin material strip to retreat together, the clamping cylinder 55 drives the pressure block to move downward to clamp and fix the material strip.

[0034] The output end of the jig 1 is also provided with a cutting die 11, which cuts the fisheye terminal strip after press-fitting into individual loose parts. The cutting die 11 in this embodiment is a common cutting die 11 in the industry and will not be described in detail in this embodiment. A CCD camera 12 for detection is provided between the cutting die 11 and the pulling mechanism 5, which is used to detect whether the fisheye pin has missed press-fitting and whether the press-fitting size is qualified and record abnormal positions.

[0035] In this embodiment, the pulling mechanism 5, the press-fitting assembly 4, the feeding assembly 3 and the cutting die 11 can realize the entire process from automatic assembly and molding of the fisheye pin and the cylinder 13 to completion of cutting and discharge, without manual operation, saving labor costs, and greatly improving production efficiency. In addition, due to the stability of mechanical assembly compared to manual assembly, the consistency of assembly is guaranteed, thereby improving the quality of the fisheye pin.
