[0025] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention. Example

[0026] like Figure 1-9 As shown, this embodiment provides an automatic assembly device for small-sized glyphs on valve bodies, which includes a device body 100, an assembly platform 110, and a feeding mechanism 120, an assembly mechanism 140 and a motion mechanism 160 provided at the assembly platform 110. The feeding mechanism 120 includes a vibratory plate 121, a linear vibrator 122, and a positioning unit. The vibratory plate 121 and the linear vibrator 122 are used together to realize the automatic sorting of the material 210 and to realize the movement of the material 210 to the assembly mechanism 140. A positioning mechanism 130 is provided on one side of the feeding mechanism 120. The positioning mechanism 130 is used to realize the positioning of the material 210 at the assembly mechanism 140. The assembly mechanism 140 includes a first support 141, a first rodless cylinder 142 is provided at the first support 141, a second rodless cylinder 143 is provided at the slider of the first rodless cylinder 142, and a first cylinder 145 is mounted on the cylinder body of the second rodless cylinder 143 via a mounting plate 144. The first cylinder 145 is perpendicular to the assembly platform 110 and its piston end is directly facing the assembly platform 110. An electromagnet is provided at the end of the cylinder rod of the first cylinder 145, and a guide fixture 170 is magnetically engaged with the electromagnet. The guide fixture 170 moves up and down via a lifting mechanism. The upper end of the guide fixture 170 is used to fit the material 210, and the lower end of the guide fixture 170 is used to fit the valve body 220. A pushing fixture 146 is provided at the slider of the second rodless cylinder 143, and the pushing fixture 146 is used to push the material 210 to the valve body 220. The motion mechanism 160 includes a linear module 161. A pneumatic gripper 162 is provided at the slider of the linear module 161. The pneumatic gripper 162 is used to grip the valve body 220. The valve body 220 moves to the assembly station under the action of the linear module 161.

[0027] In actual use, workers place the wear-resistant rings into the vibratory feeder 121. The disordered wear-resistant rings are automatically sorted by the vibratory feeder 121 and move along the track inside the vibratory feeder 121 to the linear vibrator 122. The sorted wear-resistant rings then move to the positioning mechanism 130 by the linear vibrator 122. After the positioning mechanism 130 positions the wear-resistant rings, the guide fixture 170 uses a lifting mechanism to place the wear-resistant rings on the upper end of the guide fixture 170. At this time, the first cylinder 145 drives the electromagnet to attract the guide fixture 170 and disengage the guide fixture 170 from the lifting mechanism. The electromagnet drives the guide fixture 170 to move to the assembly station under the action of the first rodless cylinder 142, waiting for assembly. The valve body 220 with the assembled O-ring is installed on the pneumatic gripper 162 by manual or automatic means. Then the valve body 220 moves to the assembly station under the action of the linear module 161 and waits for assembly. During the assembly operation, the first cylinder 145 drives the electromagnet to place the lower end of the guide fixture 170 onto the valve body 220. The valve body 220 and the wear ring can maintain axial alignment under the action of the guide fixture 170. Subsequently, the second rodless cylinder 143 drives the pusher fixture 146, which pushes the wear ring at the guide fixture 170 to the valve body 220, thus completing the assembly of the wear ring and the valve body 220. In summary, compared with the prior art, this embodiment has a higher degree of automation, which can greatly improve the installation efficiency of the product, free up manpower, and at the same time, improve the product installation yield and avoid damage to the wear ring during manual assembly.

[0028] Specifically, the positioning mechanism 130 includes a base 131 installed on the assembly platform 110, a positioning platform 132 on the upper surface of the base 131, a positioning cylinder 133 on one side of the positioning platform 132, and a guide groove 135 on the positioning platform 132. The material 210 moves to the guide groove 135 under the action of the linear vibrator 122. The cylinder rod of the positioning cylinder 133 is provided with a V-shaped plate 134 that moves in the guide groove 135. A positioning area is formed on the other side of the positioning platform 132. Two support blocks 136 that move in opposite directions or back to back are provided in the positioning area. The two support blocks 136 together form a support groove for supporting the material 210. The lifting mechanism includes a second cylinder 180 installed on the base 131. The second cylinder 180 is used to push the guide fixture 170 to the support groove.

[0029] With the above structure, when the material 210 moves to the positioning mechanism 130 via the vibrating plate 121 and the linear vibrator 122, it can move into the guide groove 135, thereby causing the positioning cylinder 133 to push the V-shaped plate 134 to push the material 210 to the support groove. Subsequently, the lifting mechanism pushes the guide fixture 170 upward so that the material 210 can be fitted onto the upper end of the guide fixture 170, waiting for the assembly mechanism 140 to act. During this process, the material 210 can be positioned well.

[0030] Specifically, positioning plates 137 are provided on both sides of the positioning area along the length of the positioning platform 132. A linear bearing is provided at the positioning plate 137, and a guide rod 138 is coaxially provided at the linear bearing. A support block 136 is provided at the end of the guide rod 138, and a compression spring 139 is provided between the support block 136 and the positioning plate 137 and sleeved on the outer wall of the guide rod 138.

[0031] With the above structure, the two support blocks 136 can maintain opposite movement under the action of the compression spring 139.

[0032] Specifically, the assembly platform 110 is also provided with a shaping mechanism 150 on one side of the assembly mechanism 140. The shaping mechanism 150 includes a second support 151 and a third cylinder 152 is provided at the second support 151. The third cylinder 152 is perpendicular to the assembly platform 110. The cylinder rod of the third cylinder 152 is provided with a shaping fixture 153. The shaping fixture 153 is sleeve-shaped and is used to shape the material 210 at the valve body 220.

[0033] With the above structure, during the shaping process, the third cylinder 152 drives the shaping fixture 153 to be fitted onto the valve body 220, so that the end edge of the shaping fixture 153 presses the material 210 onto the outer wall of the valve body 220 in a better manner, avoiding partial twisting of the material 210, so as to ensure the yield rate of the product after assembly.

[0034] Specifically, the upper end of the guide fixture 170 is shaped like a frustum.

[0035] With the above structure, it is easier for the pusher 146 to push the material 210 to the valve body 220.

[0036] Specifically, the first support 141 is perpendicular to the assembly platform 110, and one end of the first rodless cylinder 142 is installed at the end of the first support 141 and the first rodless cylinder 142 is perpendicular to the first support 141.

[0037] Specifically, the second rodless cylinder 143 is perpendicular to the first rodless cylinder 142 and the second rodless cylinder 143 is parallel to the first support 141.

[0038] A method for using an automatic assembly device for small-sized Glyd rings on a valve body, comprising the following steps: S1. Install the valve body 220 with O-rings onto the pneumatic gripper 162, and drive the linear module 161 to move the valve body 220 to the assembly station for assembly. S2. Material 210 moves to positioning mechanism 130 under the action of vibrating plate 121 and linear vibrator 122. First cylinder 145 drives electromagnet to attract guide fixture 170 and disengage guide fixture 170 from lifting mechanism. Electromagnet drives guide fixture 170 to move to assembly station under the action of first rodless cylinder 142, waiting for assembly. S3. The first cylinder 145 drives the electromagnet to place the lower end of the guide fixture 170 onto the valve body 220. The valve body 220 and the wear ring can maintain axial alignment under the action of the guide fixture 170. Subsequently, the second rodless cylinder 143 drives the pusher fixture 146, which pushes the wear ring at the guide fixture 170 to the valve body 220, completing the assembly of the wear ring and the valve body 220.

[0039] In summary, the above are merely preferred embodiments of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention shall fall within the scope of the present invention.
