[0001] The present invention relates to the technical field of fluid connectors, and particularly to a fluid docking joint, a fluid docking mechanism, and a workpiece processing device. Background Art

[0002] Currently, in the processing production line of large parts, a processing tool driven by a gas source is used to process each part of the parts. Specifically, for large parts, the processing tool needs to change different positions to ensure that the whole part is processed. In order to supply gas to the processing tool driven by the gas source, in the existing production line, gas supply joints are usually arranged at each work station to be processed, and the gas supply joints are quickly docked and matched with the docking joints arranged on the processing tool, so that the gas supply joints can supply gas to the processing tool.

[0003] However, in the automated processing production line of the prior art, when the processing tool changes its docking position between different positions, there are usually large position and angle deviations between the docking joint and the gas supply joint due to poor docking accuracy, resulting in the failure of the docking of the two, making the processing tool unable to operate and having poor reliability. Summary of the Invention

[0004] Based on this, in view of the technical problem that the docking accuracy of the gas supply joint and the docking joint in the prior art is poor, resulting in poor reliability of the processing tool, it is necessary to provide a fluid docking joint, a fluid docking mechanism, and a workpiece processing device with higher docking accuracy and better operation reliability.

[0051] The fluid docking joint, fluid docking mechanism and workpiece processing device according to the embodiments of the present application will be described below with reference to the accompanying drawings. It should be noted that the fluid in the present application can be a liquid or a gas, etc. Here, the case where the fluid is a gas is taken as an example for illustration. For the cases where the fluid is of other types, it is similar and will not be elaborated here.

[0052] Figure 1 is a schematic structural diagram of the fluid docking mechanism provided by the embodiment of the present application, Figure 2 is an exploded structural diagram of the fluid docking mechanism provided by the embodiment of the present application.

[0053] Referring to Figure 1 and Figure 2 , the embodiment of the present application provides a fluid docking mechanism 300, including a fluid docking joint 100 and a fluid supply joint 200. Among them, the fluid supply joint 200 can be communicated with a fluid supply source (not shown), and the fluid supply joint 200 is generally installed and fixed at a preset position in the work station; and the fluid in the fluid docking joint 100 can be communicated with a fluid using tool (not shown), and the fluid docking joint 100 can generally move along with the fluid using tool; thus, when the fluid supply joint 200 is docked and mated with the fluid docking joint 100, the fluid from the fluid supply source can enter the fluid using tool through the fluid supply joint 200 and the fluid docking joint 100.

[0054] It should be noted that, for the convenience of description, the relative movement direction of the fluid docking joint 100 and the fluid supply joint 200 is defined as the docking direction D, and the side of the fluid docking joint 100 facing the fluid supply joint 200 is defined as the insertion side of the fluid docking joint 100.

[0055] The structures of the fluid docking joint 100 and the fluid supply joint 200 will be described separately below.

[0056] Figure 3 It is a schematic structural diagram of the fluid docking joint provided by the embodiment of the present application. Figure 4 It is an exploded structural diagram of the fluid docking joint provided by the embodiment of the present application. Figure 5 It is another exploded structural diagram of the fluid docking joint provided by the embodiment of the present application.

[0057] Referring to Figure 3 、 Figure 4 、 Figure 5 In this embodiment, the fluid docking joint 100 is used to dock and cooperate with the fluid supply joint 200. The fluid docking joint 100 includes a docking plate 10, an outer frame 20 surrounding the periphery of the docking plate 10, and at least one connecting component 30. A docking guiding portion 15 and a fluid docking interface 12 are provided on the docking plate 10. The docking guiding portion 15 is used to guide the docking of the fluid docking joint 100 and the fluid supply joint 200, and the fluid docking interface 12 is used to communicate with the fluid supply interface 2201 of the fluid supply joint 200 when the fluid docking joint 100 and the fluid supply joint 200 are docked.

[0058] The connecting component 30 includes a plurality of elastic connecting members 33. The plurality of elastic connecting members 33 are arranged along the periphery of the docking plate 10. Each elastic connecting member 33 includes a first end 331 and a second end 332 opposite to each other. The first end 331 and the second end 332 of the elastic connecting member 33 are respectively connected to the docking plate 10 and the outer frame 20 to provide an elastic force for elastically stretching the docking plate 10 inside the outer frame 20.

[0059] In the above solution, through the elastic connecting members 33 arranged along the circumferential direction of the docking plate 10, the docking plate 10 is elastically suspended inside the outer frame 20, and an outward elastic force is applied to the docking plate 10 by the elastic connecting members 33, so that the docking plate 10 has six degrees of freedom, allowing the docking guiding portion 15 on the docking plate 10 to float with six degrees of freedom. Even if there are large position and angle deviations between the fluid docking joint 100 and the fluid supply joint 200, the docking guiding portion 15 can flexibly adjust and change its position according to the position of the fluid supply joint 200. Therefore, the docking accuracy is relatively high and the reliability is relatively good.

[0060] It should be noted that in the embodiments of the present application, the straight line passing through the center of the docking plate 10 of the fluid docking joint 100 and extending along the docking direction D is defined as the axis of the docking plate 10, and the direction around the axis of the docking plate 10 is defined as the circumferential direction of the docking plate 10.

[0061] Among them, the docking plate 10 can be integrally formed as a block or a disc, and a structure for connecting the connecting component can be formed at its edge. A fluid passage for fluid flow can be formed inside the docking plate, and both ends of the fluid passage are respectively used to communicate with the fluid usage tooling and the fluid supply joint 200. One end of the fluid passage can form the above-mentioned fluid docking interface 12.

[0062] Specifically, both ends of the fluid passage can be respectively located on the outer surface of the docking plate 10 to facilitate cooperation with other components. Exemplarily, one end of the fluid passage, such as the fluid docking interface 12, is formed on the docking side surface of the docking plate 10, that is, on the surface of the docking plate 10 facing the fluid supply joint 200, and the other end 13 of the fluid passage is formed on the surface adjacent to the docking side surface. A conversion joint 14 can be connected to the other end 13, and the conversion joint 14 can be connected to components such as fluid pipes, and the conversion joint 14 can be connected to the other end 13 of the fluid passage by threaded connection. It can be understood that the positions of both ends of the fluid passage include but are not limited to the above positions and can be set according to actual needs.

[0063] As described above, a docking guiding portion 15 is further provided on the docking plate 10, and the docking guiding portion 15 is used to guide the fluid docking joint 100 to dock with the fluid supply joint 200. Refer to Figure 2 , a guiding portion 230 can be formed on the fluid supply joint 200, and the guiding portion 230 is used to movably cooperate with the docking guiding portion 15 in the fluid docking joint 100. In specific implementation, the docking guiding portion 15 and the guiding portion 230 can be oppositely arranged. The docking guiding portion 15 can be a guiding pin, and the guiding portion 230 is a guiding hole that can be guidingly cooperated with the guiding pin. Or, the guiding portion 230 can be a guiding pin, and the docking guiding portion 15 is a guiding hole that can be guidingly cooperated with the guiding pin. In the embodiments of the present application, the case where the docking guiding portion 15 is a guiding hole and the guiding portion 230 is a guiding pin is taken as an example for description.

[0064] In the embodiments of the present application, continue to refer to Figure 2 , Figure 4 When the outer frame 20 is arranged around the circumferential side of the docking plate 10, it specifically means that the outer frame 20 surrounds the circumferential outer side of the docking plate 10. Since the connecting component 30 is connected between the outer frame 20 and the docking plate 10, it is also considered to have a certain distance between the inner edge of the outer frame 20 and the circumferential outer edge of the docking plate 10. This facilitates the docking plate 10 to be suspended inside the inner edge of the outer frame 20.

[0065] Among them, the connecting component 30 may include a plurality of elastic connecting members 33. The plurality of elastic connecting members 33 are arranged around the circumferential side of the docking plate 10. Each elastic connecting member 33 may include a first end 331 and a second end 332. The first end 331 and the second end 332 of the elastic connecting member 33 are respectively connected to the docking plate 10 and the outer frame 20 to provide an elastic force for elastically stretching the docking plate 10 inside the inner edge of the outer frame 20. The elastic connecting member 33 may be a tension spring or other elastic structures as long as it can generate a radially outward elastic pulling force on the docking plate 10.

[0066] In the embodiment of the present application, continue to refer to Figure 4 , for the connection manner between the elastic connecting member 33 and the docking plate 10, the docking plate 10 may include a docking plate body 101 and a mounting plate 102 connected to the docking plate body 101. Of course, the docking plate body 101 and the mounting plate 102 may be integrally formed or connected together through a connecting member.

[0067] Exemplarily, referring to Figure 5 , the fluid channel and the docking guiding portion 15 may both be located on the docking plate body 101. The mounting plate 102 may include a mounting edge 1023 extending to the outside of the edge of the docking plate body 101. The first end 331 of the elastic connecting member 33 may be connected to the mounting edge 1023. Specifically, the mounting edge 1023 may be an annular area. A plurality of inner mounting portions 1024 may be provided on the mounting edge 1023. The inner mounting portions 1024 may be, for example, mounting holes, and the first end 331 of the elastic connecting member 33 can be connected to the inner mounting portions 1024. Correspondingly, an outer mounting portion 1026 connected to the second end 332 of the elastic connecting member 33 may be provided on the outer frame 20. The outer mounting portion 1026 may also be a mounting hole for connecting the second end 332 of the elastic connecting member 33.

[0068] It can be understood that in order to ensure the balance of the pulling force of each elastic connecting member 33 on the docking plate 10, it can be considered that the inner mounting portions 1024 are evenly arranged around the circumferential direction of the docking plate 10, and the outer mounting portions 1026 are also evenly arranged around the circumferential direction of the docking plate 10.

[0069] Or it can also be that the inner mounting portions 1024 are evenly arranged around the circumferential direction of the docking plate 10, and the outer mounting portions do not need to be evenly arranged around the circumferential direction of the docking plate 10.

[0070] Or it can also be that the inner mounting portions 1024 do not need to be evenly arranged around the circumferential direction of the docking plate 10, while the outer mounting portions 1026 are evenly arranged around the circumferential direction of the docking plate 10.

[0071] In the embodiments of the present application, the number of the connection components 30 can be multiple, and the multiple connection components 30 can be arranged at intervals in the above docking direction D. Figure 3 , Figure 4 Taking the number of the connection components 30 as two, and the two connection components 30 being arranged at intervals in the docking direction D of the docking guiding portion 15 as an example for illustration. It can be understood that by setting two connection components 30, a force balance point is achieved between the elastic connection members 33, so that during the docking process, the position and state of the docking plate 10 can be kept relatively stable.

[0072] Specifically, the two sets of connection components 30 are respectively a first connection component 31 close to the fluid supply joint 200 and a second connection component 32 away from the fluid supply joint 200. Here, the elastic coefficient of each elastic connection member 33 in the first connection component 31 is smaller than the elastic coefficient of each elastic connection member 33 in the second connection component 32. In this way, the inclination degree of each elastic connection member 33 in the first connection component 31 can be greater than the inclination degree of each elastic connection member 33 in the second connection component 32. In this way, when the fluid docking joint 100 is docked and mated with the fluid supply joint 200, a pre-tightening force towards the fluid supply joint 200 can be generated on the fluid supply joint 200 of the docking plate 10, which is beneficial to the tight engagement of the fluid docking joint 100 and the fluid supply joint 200 to prevent fluid leakage.

[0073] In specific applications, the docking force between the connection plate 210 and the docking plate 10 can be changed by changing the inclination degree of the elastic connection members 33 in the first connection component 31 and the elastic connection members 33 in the second connection component 32, changing the diameter dimensions of the first mounting plate 1021 and the second mounting plate 1022, etc., so as to achieve compliant docking under different precision error requirements.

[0074] In the embodiments of the present application, continue to refer to Figure 4 , correspondingly to the number of the connection components 30, the number of the mounting plates 102 is also set to two. The two mounting plates 102 are respectively a first mounting plate 1021 and a second mounting plate 1022 arranged at intervals in the docking direction D. It can be understood that all the various structural features, principles, etc. of the mounting plate 102 described above are applicable to the first mounting plate 1021 and the second mounting plate 1022.

[0075] The outer frame 20 may include a first fixing plate 21 and a second fixing plate 22 spaced apart in the docking direction D. The first ends 331 of the elastic connecting members 33 in the first connecting assembly 31 are connected to the first mounting plate 1021, and the second ends 332 of the elastic connecting members 33 in the first connecting assembly 31 are connected to the first fixing plate 21; the first ends 331 of the elastic connecting members 33 in the second connecting assembly 32 are connected to the second mounting plate 1022, and the second ends 332 of the elastic connecting members 33 in the second connecting assembly 32 are connected to the second fixing plate 22.

[0076] In addition, in order to enable the outer frame 20 to provide a certain degree of protection to the docking plate 10, it can be considered that the distance between the first fixing plate 21 and the second fixing plate 22 in the docking direction D is greater than the distance between the first mounting plate 1021 and the second mounting plate 1022 in the docking direction D.

[0077] Regarding the relative positions of the two mounting plates 102 and the docking plate 10, in some embodiments, referring to Figure 4 、 Figure 5 as shown, the docking plate 10 can be clamped between the first mounting plate 1021 and the second mounting plate 1022; and avoidance windows 1025 are provided on both the first mounting plate 1021 and the second mounting plate 1022, and the positions of the avoidance windows 1025 correspond to the positions of the docking guiding portions 15, so that the docking guiding portions 15 are exposed through the avoidance windows 1025. That is, in the docking direction D, the first mounting plate 1021 and the second mounting plate 1022 do not interfere with the docking action of the docking guiding portions 15.

[0078] Furthermore, in order to protect structures such as the docking plate 10, it can be considered to provide a protection structure outside the docking plate 10 and the outer frame 20. Exemplarily, the fluid docking joint 100 further includes a shield 40 having an accommodation cavity inside. The docking plate 10 and the outer frame 20 are both disposed in the accommodation cavity inside the shield 40. An avoidance hole 41 is also provided at a position on the shield 40 corresponding to the avoidance window 1025, so that the docking guiding portions 15 are exposed through the avoidance hole 41. That is, the shield 40 also does not interfere with the docking action of the docking guiding portions 15.

[0079] The specific structure of the fluid supply joint 200 will be described below.

[0080] Figure 6 is a schematic structural diagram of the fluid supply joint in the fluid docking mechanism provided by the embodiment of the present application, Figure 7 is an exploded structural diagram of the fluid supply joint in the fluid docking mechanism provided by the embodiment of the present application.

[0081] Referring to Figure 6 、 Figure 7, the fluid supply joint 200 includes a connection disk 210, on which a guiding portion 230 and a fluid supply interface 2201 are provided. The guiding portion 230 is used for guiding and mating with the docking guiding portion 15 in the fluid docking joint 100 to guide the docking action between the fluid docking joint 100 and the fluid supply joint 200. The fluid supply interface 2201 is also communicated with a fluid supply source.

[0082] Specifically, a docking channel communicated with the fluid supply source may be provided on the connection disk 210. Among the two ends of the docking channel, one end may form the fluid supply interface 2201. When the guiding portion 230 and the docking guiding portion 15 are mated, the connection disk 210 may hermetically connect the fluid supply interface 2201 and the fluid docking interface in the fluid docking joint 100, so that the fluid channel is communicated with the fluid supply source.

[0083] In specific implementation, the docking channel may include two ends, and the two ends of the docking channel may be respectively located on the outer surface of the connection disk 210 for facilitating mating with other components. Exemplarily, one end of the docking channel is formed on the surface of the connection disk 210 facing the docking disk 10 to form the fluid supply interface 2201 of the fluid supply joint 200. The other end 2202 of the docking channel is formed on other surfaces of the connection disk 210. A conversion joint 2204 may be connected to the other end 2202. The conversion joint 2204 may be connected to components such as a fluid pipeline to be connected to the fluid supply source, and the conversion joint 2204 may be connected to the other end 2202 by threaded connection. It can be understood that the positions of the two ends of the docking channel include but are not limited to the above positions and may be set according to actual needs.

[0084] In addition, as described above, the guiding portion 230 and the docking guiding portion 15 are oppositely arranged. The guiding portion 230 is a guiding pin, and the docking guiding portion 15 is a guiding hole that can be guided and mated with the guiding pin.

[0085] To improve the guiding effect of the guiding pin and the guiding hole, the number of guiding pins may be two. For example, referring to Figure 6 、 Figure 7, the guiding pins may include a first guiding pin 241 and a second guiding pin 242, and the guiding holes include a first guiding hole 161 correspondingly arranged with the first guiding pin 241 and a second guiding hole 162 correspondingly arranged with the second guiding pin 242; the axial length of the first guiding pin 241 is greater than that of the second guiding pin 242. In this way, when the docking plate 10 and the connecting plate 210 approach and cooperate with each other, the first guiding pin 241 first contacts the first guiding hole 161 and performs a rough alignment. After the positioning is roughly completed, the second guiding pin 242 and the second guiding hole 162 perform further positioning, making the positioning process smoother and more flexible. At the same time, by setting the second guiding pin 242, the automatic alignment of the docking plate 10 in the docking direction D can be realized, so that the docking surfaces of the docking plate 10 and the connecting plate 210 are completely fitted.

[0086] In addition, the first guiding pin 241 includes a large-diameter section 2411 connected to the connecting plate 210 and a small-diameter section 2412 facing away from the connecting plate 210, and the diameter of the small-diameter section 2412 gradually decreases along the direction away from the connecting plate 210; the axial length of the second guiding pin 242 is less than the axial length of the large-diameter section 2411. Since the small-diameter section 2412 is arranged in a conical shape, the docking of the first guiding pin 241 and the first guiding hole 161 can be guided. The axial length of the second guiding pin 242 is less than that of the large-diameter section 2411, which can ensure that after the contact between the small-diameter section 2412 and the first guiding hole 161 is completed, the second guiding pin 242 and the second guiding hole 162 are then fitted.

[0087] It can be understood that the diameter difference between the two end faces of the small-diameter section 2412 determines the maximum allowable error of the docking center of the docking plate 10 and the connecting plate 210. By changing the diameter, length and taper of the conical small-diameter section 2412, compliant docking under different docking error requirements can be achieved.

[0088] Continue to refer to Figure 7 , the fluid docking mechanism 300 further includes a driving assembly 310, and the driving assembly 310 includes a cylinder 311, a cylinder bracket 312, and a cylinder shield 313. The cylinder 311 is supported on the cylinder bracket 312, and the cylinder shield 313 covers the outside of the cylinder 311 to achieve effects such as dust prevention.

[0089] Specifically, the cylinder 311 includes a cylinder block 3111, a piston rod 3112, and a cylinder fixing plate 3113. The cylinder block 3111 can be fixedly connected to the cylinder bracket 312 by bolts. One side of the piston rod 3112 is slidably connected to the cylinder block 3111, and the other side of the piston rod 3112 is fixedly connected to the cylinder fixing plate 3113. The cylinder guard 313 is fixedly bolted to the outside of the cylinder fixing plate 3113, and the connecting plate 210 is fixedly connected to the cylinder fixing plate 3113. In this way, when the piston rod 3112 drives the cylinder fixing plate 3113 to move along the docking direction D, the connecting plate 210 can be driven to move relative to the docking plate 10 in the docking direction D.

[0090] Next, refer to Figure 7 to describe the docking process of the fluid docking mechanism 300 of this embodiment.

[0091] When the fluid docking mechanism 300 of this embodiment is docking, the fluid docking joint 100 approaches the fluid supply joint 200. The cylinder 311 acts to drive the cylinder fixing plate 3113 to drive the connecting plate 210 to move along the docking direction D towards the docking plate 10. The small-diameter section 2412 of the first guide pin 241 first contacts the edge of the first guide hole 161 on the docking plate 10. As the connecting plate 210 continues to move towards the docking plate 10, the large-diameter section 2411 of the first guide pin 241 contacts the first guide hole 161. At this time, the second guide pin 242 slides along the inner wall of the second guide hole 162 to achieve complete alignment and fitting of the connecting plate 210 and the docking plate 10. At this time, the fluid docking interface 12 is connected to the fluid supply interface 2201, and the docking is completed.

[0092] During the above docking process, the elastic connectors 33 in the first connection assembly 31 and the elastic connectors 33 in the second connection assembly 32 act together to enable the docking plate 10 to float smoothly in six degrees of freedom, so that the docking surfaces of the docking plate 10 and the connecting plate 210 are completely aligned and fitted, and a pre-compression force is provided to the connecting plate 210, which can ensure the docking airtightness between the fluid supply interface 2201 and the fluid docking interface 12.

[0093] When the mechanism separates, the cylinder 311 acts to drive the cylinder fixing plate 3113 to drive the connecting plate 210 to retreat, that is, to move in a direction away from the docking plate 10. The fluid docking interface 12 is separated from the fluid supply interface 2201, and the first guide pin 241 slides and separates in the first guide hole 161. Further, the second guide pin 242 slides and separates in the second guide hole 162. During the separation process, the first connection assembly 31 and the second connection assembly 32 in the fluid docking joint 100 act together to enable the connecting plate 210 to smoothly return to its original position, realizing compliant separation. In addition, since the docking plate 10 can float in six degrees of freedom, it can achieve compliant docking of the fluid docking joint 100 and the fluid supply joint 200 within a relatively large error range.

[0094] Figure 8 This is a schematic structural diagram of the workpiece processing device provided by the embodiment of the present application.

[0095] Referring to Figure 8 , the embodiment of the present application also provides a workpiece processing device 500, including a clamping mechanism 510 and the above-mentioned fluid docking mechanism 300. The fluid supply joint 200 in the fluid docking mechanism 300 is connected to the clamping mechanism 510.

[0096] Among them, the specific structure, function, working principle, etc. of the fluid docking mechanism 300 have been described in detail above and will not be elaborated here.

[0097] In this embodiment, a clamping mechanism 510 is provided at the processing station of the workpiece 400. The clamping mechanism 510 includes a clamping mechanism main body 520 and legs 530 supported on the lower side of the clamping mechanism main body 520. The workpiece 400 can be clamped on the clamping mechanism main body 520.

[0098] The fluid supply joint 200 can be arranged on the clamping mechanism 510, for example, on the legs 530. The fluid supply joint 200 can communicate with the fluid supply source. The fluid docking joint 100 can be relatively fixed to the tooling (fluid-using tooling) for processing the workpiece 400. For example, both the fluid docking joint 100 and the fluid-using tooling can be arranged on a movable AGV trolley.

[0099] When the fluid-using tooling needs to process Figure 7 the position shown on the right side of the drawing, the AGV trolley can carry the fluid-using tooling and the fluid docking joint 100 to dock with the fluid supply joint 200 shown on the right side, so that the fluid supply source supplies fluid to the fluid-using tooling. When the processing of the right side position of the workpiece 400 is completed and it is necessary to process other positions of the workpiece 400, for example, the middle part of the workpiece 400, the AGV trolley can carry the fluid-using tooling and the fluid docking joint 100 to Figure 7 dock with the fluid supply joint 200 shown in the middle of the drawing, so that the fluid supply source supplies fluid to the fluid-using tooling. Of course, the setting position of the fluid supply joint 200 is not limited to this and can be set according to actual needs.

[0100] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0101] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
