[0048] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0049] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0051] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] This embodiment provides an O-ring automatic assembly device, which can realize automatic loading, assembly and unloading of O-rings 200 and aluminum sheets. The whole process does not require manual operation, which saves manpower and improves assembly efficiency. Figure 1 and Figure 2As shown, the O-ring automatic assembly device includes a mounting plate 10, a feeding mechanism 20, an O-ring positioning mechanism 30, an O-ring opening mechanism 40 and a transfer mechanism 50. The feeding mechanism 20 is mounted on the mounting plate 10. The feeding mechanism 20 includes a first feeding member 21 and a second feeding member 22. The first feeding member 21 has a first discharge position 211, and a plurality of O-rings 200 can be intermittently discharged from the first discharge position 211. The second feeding member 22 has a second discharge position 221, and a plurality of aluminum sheets can be intermittently discharged from the second discharge position 221. The O-ring positioning mechanism 30 can transfer the O-ring 200 located at the first discharge position 211 to the assembly position 11 and position the O-ring 200. The O-ring opening mechanism 40 is a transfer mechanism 50. The O-ring stretching mechanism 40 is located below the assembly position 11. The O-ring stretching mechanism 40 includes a lifting drive 41 and a stretching component 42 connected to the output end of the lifting drive 41. The lifting drive 41 can drive the stretching component 42 to reciprocate along the second direction (the Y direction in the figure). The stretching component 42 can pass through the O-ring 200 located at the assembly position 11 and stretch or loosen the O-ring 200. The assembly position 11 and the second discharge position 221 are spaced apart along the first direction (the X direction in the figure, the X direction is perpendicular to the Y direction); the transfer mechanism 50 can transfer the aluminum sheet from the second discharge position 221 to the assembly position 11, and transfer the aluminum sheet with the O-ring 200 assembled on the assembly position 11 to the discharge chute 61.

[0053] The process of assembling the aluminum sheet and the O-ring 200 by the above-mentioned automatic O-ring assembly device is as follows: the O-ring 200 is sequentially fed out through the first feeding piece 21 until it is conveyed to the first discharge position 211; the aluminum sheet is sequentially fed out through the second feeding piece 22 until it is conveyed to the second discharge position 221. The O-ring positioning mechanism 30 transfers the O-ring 200 located at the first discharge position 211 to the assembly position 11 and positions the O-ring 200 to ensure that it is subsequently accurately opened. Then, the lifting drive member 41 drives the opening component 42 to rise. At this time, the opening component 42 is in a retracted state and can be inserted into the O-ring 200. Then, the O-ring 200 is opened. The inner diameter of the opened O-ring 200 is larger than the outer diameter of the aluminum sheet. Then, the transfer mechanism 50 transfers the aluminum sheet from the second discharge position 221 to the assembly position 11. At this time, the aluminum sheet is located inside the expanded O-ring 200. At this time, the lifting drive member 41 descends, and the mounting plate 10 forces the expansion assembly 42 to separate from the O-ring 200. The O-ring 200 is automatically sleeved on the aluminum sheet. Then, the transfer mechanism 50 carries the aluminum sheet with the O-ring 200 installed and puts it into the unloading chute 61, ready for the next assembly. During the whole process, the loading, assembly and unloading of the O-ring 200 and the aluminum sheet are realized. The whole process does not require manual operation, which saves manpower and improves assembly efficiency.

[0054] Alternatively, if Figure 1As shown, the transfer mechanism 50 includes a gantry 51, a transverse moving module 52, a longitudinal driving member 53 and a picking member 54. The gantry 51 is mounted on the mounting plate 10 and extends along the first direction; the transverse moving module 52 is mounted on the gantry 51, and the transverse moving module 52 can output movement along the first direction; the longitudinal driving member 53 is mounted on the output end of the transverse moving module 52, and the longitudinal driving member 53 can output movement along the second direction; the picking member 54 is mounted on the output end of the longitudinal driving member 53, and the picking member 54 can pick up or release the aluminum sheet. Through the above arrangement, the transverse moving module 52 realizes the position change of the picking member 54 in the first direction, and the longitudinal driving member 53 realizes the position change of the picking member 54 in the second direction (i.e., the vertical direction). It should be noted that the transverse moving module 52 and the longitudinal driving member 53 can be any driving element that outputs linear motion, such as a combination of a motor, a lead screw and a nut, a cylinder, etc., which are not limited here.

[0055] Optionally, the picking member 54 can adsorb or release the aluminum sheet. With the above arrangement, on the one hand, the adsorption method will not cause wear to the surface of the aluminum sheet, and on the other hand, the picking position will not occupy the position for assembling the O-ring 200 on the side of the aluminum sheet. It is understandable that the picking member 54 is connected to the vacuum generator, and when picking up the aluminum sheet, placing the aluminum sheet, and before transferring the aluminum sheet to the unloading chute 61, the vacuum generator is in working condition, so that the picking member 54 can adsorb the aluminum sheet; when unloading, the vacuum generator stops working, the picking member 54 is separated from the aluminum sheet, and the unloading is completed. Optionally, as Figure 1 As shown, a discharge barrel 60 is provided at the discharge chute 61 , which can collect a certain number of assembled aluminum sheets and O-rings 200 .

[0056] Optionally, the head of the picking member 54 is arranged in a step shape, so that when the picking member 54 is pressed down to the assembly position 11, the step surface can limit the O-ring 200 to prevent the O-ring 200 from bouncing open when the lifting drive member 41 drives the support assembly 42 to descend.

[0057] Alternatively, if Figure 1 As shown, the feed chute 61, the second discharge position 221 and the assembly position 11 are spaced apart in the first direction. The above arrangement makes it unnecessary for the pick-up member 54 to move in the third direction (Z direction in the figure, which is perpendicular to the X direction and the Y direction respectively), thereby reducing the setting of a driving element and simplifying the structure.

[0058] Alternatively, if Figure 2As shown, the O-ring positioning mechanism 30 includes a pushing assembly 31 and a positioning assembly 32, which are respectively located on opposite sides of the first discharge position 211 in the first direction and are both mounted on the mounting plate 10. The pushing assembly 31 can push the O-ring 200 located at the first discharge position 211 to the assembly position 11, and the positioning assembly 32 can position the O-ring 200 at the assembly position 11. It can be understood that the O-ring screened by the first feeding member 21 also has a slight deviation in the position of the first discharge position 211, and it is pushed to the assembly position 11 for positioning to ensure the accuracy of the position when the opening assembly 42 opens the O-ring 200.

[0059] Alternatively, if Figure 2 As shown, in order to ensure the accuracy of the position of the aluminum sheet at the second discharge position 221, the second discharge position 221 is provided with a U-shaped groove adapted to the shape of the aluminum sheet, and the opening of the U-shaped groove faces the discharge end of the second loading member 22, ensuring that the picking member 54 can accurately pick up the aluminum sheet.

[0060] It should be noted that the first loading member 21 and the second loading member 22 discharge materials by the vibration principle, which is a prior art and will not be described in detail herein.

[0061] Alternatively, if Figure 2 As shown, the pushing assembly 31 includes a pushing drive 311 and a pushing member 312. The pushing drive 311 is installed on the mounting plate 10, and the pushing member 312 is installed at the output end of the pushing drive 311. The pushing drive 311 can drive the pushing member 312 to reciprocate along the first direction so that the O-ring 200 located at the first discharge position 211 reaches the assembly position 11.

[0062] Alternatively, if Figure 2 As shown, the positioning assembly 32 includes a clamping drive 321 and two limit blocks 322. The clamping drive 321 is installed on the mounting plate 10; the two limit blocks 322 are installed at the output end of the clamping drive 321. The clamping drive 321 can drive the two limit blocks 322 to move closer to or away from each other. The two limit blocks 322 are provided with an arc surface 3221 that matches the shape of the O-ring 200 on one side close to the O-ring 200. Through the above arrangement, the clamping drive 321 drives the limit blocks 322 to move closer to each other, thereby accurately positioning the O-ring 200 on the assembly position 11. At the same time, the arrangement of the arc surface 3221 can make the O-ring 200 be positioned more accurately.

[0063] Alternatively, if Figure 3As shown, the O-ring expansion mechanism 40 also includes a first mounting member 43 and a second mounting member 46. The first mounting member 43 is located at the lower side of the mounting plate 10 and is connected to the mounting plate 10 through a guide column 44. The lifting drive member 41 is installed on the first mounting member 43; the second mounting member 46 is located between the mounting plate 10 and the first mounting member 43 and is installed at the output end of the lifting drive member 41. The expansion assembly 42 is installed on the second mounting member 46. A guide sleeve 45 is installed on the second mounting member 46. The guide sleeve 45 and the guide column 44 are slidably matched. Through the above arrangement, it is ensured that the lifting drive member 41 is more stable and does not deviate during the process of driving the expansion assembly 42 to rise or fall.

[0064] Alternatively, if Figure 4 and Figure 5 As shown, the spreading assembly 42 includes a spreading drive 421 and at least three claws 422. The spreading drive 421 is mounted on the second mounting member 46. The at least three claws 422 are all mounted on the output end of the spreading drive 421 and are arranged radially and evenly spaced. The spreading drive 421 can drive the three claws 422 to approach or move away from the center. The mounting plate 10 is provided with an avoidance groove 13 at the assembly position 11 to match the trajectory of the at least three claws 422. Through the above arrangement, when the lifting drive 41 drives the spreading assembly 42 to rise, at least three claws 422 are in a close state, and the three claws 422 can extend into the O-ring 200 at the assembly position 11. Then, the spreading drive 421 drives the three claws 422 to move away from each other to spread the O-ring 200. In this embodiment, four claws 422 are provided. In other embodiments, the number of claws 422 can also be set to three, five or more, which is not limited here. Among them, the structure in which the spreading driving member 421 simultaneously drives the four spreading claws 422 to move closer or farther away is relatively common in the prior art, and its principle and internal structure are not described in detail here.

[0065] Alternatively, if Figure 4 As shown, the claw 422 includes a horizontal portion 4221 and a vertical portion 4222. The horizontal portion 4221 is connected to the output end of the opening driving member 421. The vertical portion 4222 is connected to the horizontal portion 4221. The vertical portion 4222 is provided with a limiting groove 42221. The opened O-ring 200 is limited in the limiting groove 42221. Through the above arrangement, the limiting groove 42221 can prevent the O-ring 200 from bouncing off during the opening process.

[0066] Optionally, both sides of the limiting groove 42221 are smoothly transitioned, so that when the supporting claw 422 descends to the lower side of the mounting plate 10 , the O-ring 200 can be smoothly removed along the vertical portion 4222 .

[0067] In this embodiment, Figure 5As shown, the avoidance groove 13 is cross-shaped and avoids the movement trajectory of the four claws 422. In other embodiments, the number of sub-grooves in the avoidance groove 13 can be adaptively adjusted according to the number of claws 422, which is not limited here. At the same time, the opening of the avoidance groove 13 does not affect the placement of the O-ring 200, preventing the O-ring 200 from falling from the avoidance groove 13.

[0068] Optionally, the O-ring automatic assembly device further includes a plurality of detection devices (not marked), and the first discharge position 211, the second discharge position 221 and the assembly position 11 are each provided with detection devices correspondingly, and the detection devices are used to detect whether there is an O-ring 200 at the corresponding station. Through the above arrangement, the action of the O-ring 200 automatic assembly device is more coherent. Specifically, the detection device can be a photoelectric sensor or a distance sensor, etc., which is not limited here.

[0069] This embodiment also provides a ball valve production line, including the above-mentioned O-ring automatic assembly device. The ball valve production line is provided with the above-mentioned O-ring automatic assembly device, and the O-ring 200 and the aluminum sheet are automatically loaded, assembled and unloaded, making the production line more automated, saving manpower and improving assembly efficiency.

[0070] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
