It should be understood that the embodiments are only for explaining the present invention rather than limiting it. Embodiment

[0026] As Figures 1-9 shown, this embodiment provides an automatic assembly device for small-sized O-rings on a valve body, which includes a device main body 100. The device main body 100 includes an assembly platform 110, and a feeding mechanism 120, an assembly mechanism 140 and a motion mechanism 160 are arranged at the assembly platform 110; The feeding mechanism 120 includes a vibrating bowl 121, a linear vibrator 122 and a positioning unit. The vibrating bowl 121 and the linear vibrator 122 are jointly used to automatically sort the materials 210 and to move the materials 210 to the assembly mechanism 140. A positioning mechanism 130 is provided on one side of the feeding mechanism 120, and the positioning mechanism 130 is used to position the materials 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. A first cylinder 145 is installed at the cylinder body of the second rodless cylinder 143 through a mounting plate 144. The first cylinder 145 is perpendicular to the assembly platform 110 and the piston end faces the assembly platform 110. An electromagnet is provided at the end of the cylinder rod of the first cylinder 145. A guiding tooling 170 is magnetically engaged with the electromagnet. The guiding tooling 170 moves up and down through a lifting mechanism. The upper end of the guiding tooling 170 is used to sleeved with the material 210, and the lower end of the guiding tooling 170 is used to sleeved with the valve body 220; A pushing tooling 146 is provided at the slider of the second rodless cylinder 143, and the pushing tooling 146 is used to push the material 210 to the valve body 220; The moving 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 grab the valve body 220, and the valve body 220 moves to the assembly station under the action of the linear module 161.

[0027] In actual use of this embodiment, the worker puts the wear-resistant rings into the vibrating bowl 121. The disordered wear-resistant rings can be automatically sorted under the action of the vibrating bowl 121 and move along the track inside the vibrating bowl 121 to the linear vibrator 122. Subsequently, the sorted wear-resistant rings move to the positioning mechanism 130 under the action of the linear vibrator 122. After the positioning mechanism 130 positions the wear-resistant rings, the guiding tooling 170 sleeved the wear-resistant rings at the upper end of the guiding tooling 170 through the lifting mechanism. At this time, the first cylinder 145 drives the electromagnet to attract the guiding tooling 170 and makes the guiding tooling 170 disengage from the lifting mechanism. The electromagnet drives the guiding tooling 170 to move to the assembly station under the action of the first rodless cylinder 142 and waits for assembly; The valve body 220 with the O-ring already assembled is installed at the pneumatic gripper 162 manually or automatically. Subsequently, the valve body 220 moves to the assembly station under the action of the linear module 161 and waits for assembly; When performing the assembly operation, the first cylinder 145 drives the electromagnet to sleave the lower end of the guiding tooling 170 on the valve body 220. The valve body 220 and the wear-resistant ring can be kept axially aligned under the action of the guiding tooling 170. Subsequently, the second rodless cylinder 143 drives the feeding tooling 146, so that the feeding tooling 146 pushes the wear-resistant ring at the guiding tooling 170 to the valve body 220, completing the assembly of the wear-resistant ring and the valve body 220. In summary, compared with the prior art, the automation degree of this embodiment is relatively high, which can greatly improve the installation efficiency of products, liberate human resources. At the same time, it can also improve the qualified rate of product installation and avoid the situation that the wear-resistant ring is damaged during manual assembly.

[0028] Specifically, the positioning mechanism 130 includes a base 131 installed on the assembly platform 110. A positioning platform 132 is provided on the upper end surface of the base 131. A positioning cylinder 133 is provided on one side of the positioning platform 132. A guiding groove 135 is provided on the positioning platform 132.

The lifting mechanism includes a second cylinder 180 provided at the base 131, and the second cylinder 180 is used to push the guiding tooling 170 to the support groove.

[0029] Through the above structure, when the material 210 moves from the vibrating disc 121 and the linear vibrator 122 to the positioning mechanism 130, it can move into the guiding groove 135. Then, the positioning cylinder 133 pushes the V-shaped plate 134 to push the material 210 to the support groove. Subsequently, the lifting mechanism pushes the guiding tooling 170 upward, so that the material 210 can be sleaved on the upper end of the guiding tooling 170 and wait for the action of the assembly mechanism 140. During this process, the material 210 can be better positioned.

[0030] Specifically, positioning plates 137 are provided on both sides of the positioning area along the length direction of the positioning platform 132. Linear bearings are provided on the positioning plates 137. Guide rods 138 are coaxially arranged at the linear bearings. The support blocks 136 are arranged at the ends of the guide rods 138. A compression spring 139 sleaving on the outer wall of the guide rod 138 is provided between the support blocks 136 and the positioning plates 137.

[0031] Through the above structure, the two support blocks 136 can move towards each other under the action of the compression spring 139.

A shaping tool 153 is provided on the cylinder rod of the third cylinder 152. The shaping tool 153 is in a sleeve shape and is used to shape the material 210 at the valve body 220.

[0033] With the above structure, when shaping, the third cylinder 152 drives the shaping tool 153 to be sleeved at the valve body 220, so that the end edge of the shaping tool 153 can better press the material 210 against the outer wall of the valve body 220, avoiding the occurrence of partial distortion of the material 210 and ensuring the yield rate of the assembled product.

[0034] Specifically, the upper end of the guiding tool 170 is in a frustum shape.

[0035] With the above structure, it is thus more convenient for the material pushing tool 146 to push the material 210 to the valve body 220.

[0036] Specifically, the first support 141 is perpendicular to the assembly platform 110. 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 usage method of an automatic assembly device for small - size Grease Rings on a valve body is realized by using an automatic assembly device for small - size Grease Rings on a valve body, and it includes the following steps: S1. Install the valve body 220 with an O - ring at the pneumatic gripper 162, and drive the linear module 161 to move the valve body 220 to the assembly station for waiting for assembly; S2. The material 210 moves to the positioning mechanism 130 under the action of the vibrating disk 121 and the linear vibrator 122. The first cylinder 145 drives the electromagnet to attract the guiding tool 170 and makes the guiding tool 170 disengage from the lifting mechanism. The electromagnet drives the guiding tool 170 to move to the assembly station under the action of the first rodless cylinder 142 for waiting for assembly; S3. The first cylinder 145 drives the electromagnet to sleeve the lower end of the guiding tool 170 at the valve body 220. The valve body 220 and the wear - resistant ring can be kept axially aligned under the action of the guiding tool 170. Subsequently, the second rodless cylinder 143 drives the material pushing tool 146, so that the material pushing tool 146 pushes the wear - resistant ring at the guiding tool 170 to the valve body 220 to complete the assembly of the wear - resistant ring and the valve body 220.
