[0038] It should be noted that the terms "include", "have" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] It should be noted that, in the embodiments of the present application, at least two includes two and more than two, and a plurality includes two and more than two.
[0040] In the related art, the replacement of welding tools requires first manually removing the original welding tools on the welding station, and then manually replacing them with the required welding tools.
[0041] An embodiment of the present application provides a welding device, including a welding device 1 and a conveying device 2, the conveying device 2 includes a conveying frame 22, a power assembly 21 and a carrier 23 for carrying welding tools, the conveying frame 22 has a work station 2a to be replaced and at least two buffer stations 2b, the carrier 23 is movably arranged on the conveying frame 22, the power assembly 21 drives the carrier 23 to move between the work station 2a to be replaced and the buffer station 2b, and the welding tools can be transported between the welding device 1 and the carrier 23 located at the work station 2a to be replaced.
[0042] The carrier 23 is movably arranged on the conveyor frame 22, and the power assembly 21 drives the carrier 23 to move between the work station 2a to be replaced and the buffer station 2b. In this way, under the drive of the power assembly 21, the carrier 23 can carry the welding tool to move between the work station 2a to be replaced and the buffer station 2b, that is, under the drive of the power assembly 21, the welding tool can move between the work station 2a to be replaced and the buffer station 2b. The conveyor frame 22 has a work station 2a to be replaced and at least two buffer stations 2b. In this way, the welding tool can move between any buffer station 2b and the work station 2a to be replaced. A plurality of buffer stations 2b are provided, which can simultaneously carry the welding tool unloaded from the welding device 1 and the welding tool to be replaced to the welding device 1.
[0043] The welding tool can be transported between the welding device 1 and the carrier 23 located at the workstation 2a to be replaced. The transport method is not specifically limited. For example, it can be roller transport or belt transport, etc. In this way, the welding tool can be transported between the welding device 1 and the workstation 2a to be replaced. The welding tool can move between any buffer workstation 2b and the workstation 2a to be replaced. The welding tool can be transported between the welding device 1 and the workstation 2a to be replaced. That is to say, the welding tool can be transported from the welding device 1 to any buffer workstation 2a to be replaced, and then to any buffer workstation 2b. The welding tool can also be transported from any buffer workstation 2b to the welding device 1 via the workstation 2a to be replaced.
[0044] As an example, suppose that there is welding tool A on the welding device 1, and welding tool A needs to be replaced with welding tool B. When welding tool A on the welding device 1 needs to be replaced, there may be no welding tool on one cache station 2b, and there may be welding tool B to be replaced on another cache station 2b. The welding tool A on the welding device 1 is transported to the cache station 2b without welding tool via the station 2a to be replaced, and then the welding tool B on the other cache station is transported to the welding device 1 via the station 2a to be replaced, so that the welding tool A and the welding tool B can be replaced.
[0045] It can be understood that the above is only an exemplary description of the replacement of the welding tooling, and does not limit the specific structure of the welding tooling. The welding tooling can be a structural part in the prior art.
[0046] The welding equipment provided in the embodiment of the present application drives the carrier 23 to move between the work station 2a to be replaced and at least two cache stations 2b through the power assembly 21, so that the welding tools removed from the welding device 1 and the welding tools to be replaced can be conveniently transported between the work station 2a to be replaced and the cache station 2b, thereby reducing manual handling and improving the convenience of tool replacement.
[0047] In some embodiments, each cache station 2 b corresponds to a vehicle 23 , and the power assembly 21 includes a power unit 211 and a transmission 212 . The transmission 212 selectively establishes or cuts off a power transmission path between the power unit 211 and any vehicle 23 .
[0048] Each buffer station 2b corresponds to a carrier 23, that is, at least two buffer stations 2b correspond to at least two carriers 23, and each carrier 23 may or may not have a welding tool. For example, at least one carrier 23 of a buffer station 2b is empty, and an empty carrier 23 means that the carrier 23 has no welding tool. Each carrier 23 can move independently.
[0049] Still taking the replacement of welding tool A and welding tool B as an example, the empty carrier 23 is first moved from the cache station 2b to the replacement station 2a and carries the welding tool A from the welding device 1, and then returns to the original cache station 2b via the replacement station 2a; another carrier 23 carrying the welding tool B moves from the cache station 2b where it is located to the replacement station 2a and transports the welding tool B to the welding device 1, thereby realizing the replacement of welding tool A and welding tool B.
[0050] The transmission 212 selectively establishes or cuts off the power transmission path between the power device 211 and any one of the vehicles 23. That is, the transmission 212 can establish a power transmission path between the power device 211 and any one of the vehicles 23, and at this time the power device 211 can drive the vehicle 23 with the established power transmission path to move; the transmission 212 can also cut off the power transmission path between the power device 211 and any one of the vehicles 23, and at this time the power device 211 cannot drive the vehicle 23 with the established power transmission path to move.
[0051] Each buffer station 2b corresponds to a carrier 23, and the transmission device 212 selectively establishes or cuts off the power transmission path between the power device 211 and any carrier 23. In this way, any carrier 23 can be selectively driven by a power device 211 to move between the buffer station 2b and the station to be replaced 2a, which facilitates the flexible transportation of multiple welding tools between the buffer station 2b and the station to be replaced 2a, reduces the number of power devices 211, and saves costs.
[0052] As an example, it is assumed that there is welding tool A on the welding device 1, and welding tool A on the welding device 1 needs to be replaced with welding tool B. At this time, any one of the carriers 23 may be without a welding tool, and another carrier 23 may be equipped with a welding tool B. The transmission 212 can establish a power transmission path between the power device 211 and any one of the carriers 23 without a welding tool. The power device 211 drives the carrier 23 without a welding tool to be transported to the workstation 2a to be replaced, and is used to carry the welding tool A transported from the welding device 1 to the workstation 2a to be replaced. After the power device 211 drives the carrier 23 carrying the welding tool A to the cache workstation 2b, the transmission 212 can release the power transmission path between the transmission 212 and the carrier 23 carrying the welding tool A, and then establish a power transmission path between the transmission 212 and the carrier 23 carrying the welding tool B. The power device 211 drives the carrier 23 carrying the welding tool B to be transported to the workstation 2a to be replaced, and the welding tool B can be transported from the workstation 2a to be replaced to the welding device 1, and the replacement is completed.
[0053] In some embodiments, the transmission 212 includes a transmission cylinder 2121 disposed on the power device 211, and the vehicle 23 is formed with a socket 23a; the piston rod of the transmission cylinder 2121 is inserted into the socket 23a of any one of the vehicles 23 to establish a power transmission path; the piston rod of the transmission cylinder 2121 is disengaged from the socket 23a of any one of the vehicles 23 to cut off the power transmission path.
[0054] The transmission device 212 includes a transmission cylinder 2121 disposed on the power device 211, and the carrier 23 is formed with a socket 23a, so that the power device 211 can be connected or disconnected with the carrier 23. Taking any one of the carriers 23 as an example, the piston rod of the transmission cylinder 2121 is inserted into the socket 23a of any one of the carriers 23, and the power device 211 can form a detachable connection with the carrier 23 to establish a power transmission path between the power device 211 and the carrier 23, and the power device 211 can drive the carrier 23 to move; the piston rod of the transmission cylinder 2121 is disengaged from the socket 23a of any one of the carriers 23, and the power device 211 can be disconnected from the carrier 23 to cut off the power transmission path between the power device 211 and the carrier 23, and the power device 211 cannot drive the carrier 23 to move.
[0055] In this way, by inserting or removing the piston rod of the transmission cylinder 2121 from the socket 23 a of any carrier 23 , it is convenient to selectively establish or cut off the power transmission path between the power device 211 and the carriers 23 at different positions on the conveyor frame 22 .
[0056] The position, number and specific shape of the socket 23a are not specifically limited and can be adjusted according to actual conditions.
[0057] Each transmission cylinder 2121 may correspond to a socket 23a on a single carrier 23. Exemplarily, the number of transmission cylinders 2121 is two, and a single carrier 23 may have two sockets 23a.
[0058] In some embodiments, at least two carriers 23 are arranged at intervals along the first direction, and the power device 211 is located between two adjacent carriers 23 .
[0059] As an example, see Figure 1 The first direction is the moving direction of the carrier 23, and the first direction includes two opposite directions, that is, at least two carriers 23 can move back and forth along the two opposite directions of the first direction.
[0060] At least two carriers 23 are arranged at intervals along the first direction, and the power device 211 is located between two adjacent carriers 23. In this way, the power device 211 can conveniently transmit power to the two adjacent carriers 23 to drive the two carriers 23 adjacent to the power device 211 to move along the first direction.
[0061] Exemplarily, two transmission cylinders 2121 may be arranged on the power device 211 at intervals along the second direction, and two spaced-apart sockets 23 a are arranged at one end of the single carrier 23 close to the power device 211 along the first direction.
[0062] In some embodiments, the power device 211 is movably disposed on the conveyor frame 22, that is, the power device 211 is movable on the conveyor frame 22. In this way, the power device 211 can move to the position where the carrier 23 is located, so as to drive the carrier 23 to move between the waiting station 2a and the buffer station 2b.
[0063] In some embodiments, the conveying device 2 includes a reversing member 221 disposed on the conveying frame 22, the power device 211 includes a base 2111 and a rotating member 2114, the rotating member 2114 is rotatably connected to the base 2111, the transmission 212 is disposed on the base 2111, the rotating member 2114 is meshed with the reversing member 221, and the rotating member 2114 rotates to drive the base 2111 to perform linear reciprocating motion.
[0064] The reversing member 221 is arranged on the conveying frame 22, and the rotating member 2114 is meshed with the reversing member 221. In this way, torque can be transmitted between the rotating member 2114 and the reversing member 221, and the rotation process of the rotating member 2114 itself can be converted into a linear movement process on the conveying frame 22, that is, the power device 211 can move on the conveying frame 22 through the rotating member 2114.
[0065] The transmission device 212 is disposed on the base 2111 , and the rotating member 2114 is rotatably connected to the base 2111 . The rotating member 2114 rotates to drive the base 2111 to perform linear reciprocating motion. Thus, the rotating member 2114 can drive the transmission device 212 to perform linear reciprocating motion.
[0066] The rotating member 2114 and the reversing member 221 are meshed, and the meshing manner is not limited, for example, including but not limited to helical gear meshing or worm gear meshing.
[0067] For some examples, see Figure 2 and Figure 3 The rotating member 2114 includes a gear set 2115 , the gear set 2115 includes at least one gear, and the reversing member 221 includes a rack 2211 , and the rack 2211 is meshed with a gear in the gear set 2115 .
[0068] The meshing of the gear and the rack 2211 refers to the process in which the gear teeth and the tooth grooves of the rack 2211 mesh with each other and push each other alternately, and the rack 2211 can convert the rotational motion of the gear into linear motion. The gear meshes with the rack 2211, so that the gear rotates on the rack 2211, and the rotating member 2114 can drive the base 2111 to perform linear reciprocating motion on the conveying frame 22.
[0069] The number of teeth and shape of the gear are not specifically limited, and the number of teeth and / or shape of the gear can be changed according to actual conditions.
[0070] In some embodiments, the power device 211 includes a power source 2113 and a rotating shaft 2112, the power source 2113 is disposed on the base 2111, the rotating shaft 2112 is rotatably connected to the base 2111, the rotating member 2114 is connected to the rotating shaft 2112, and the power source 2113 is connected to the rotating shaft 2112 to drive the rotating member 2114 to rotate.
[0071] The power source 2113 is disposed on the base 2111, and the rotating shaft 2112 is rotatably connected to the base 2111, that is, the power source 2113 can drive the rotating shaft 2112 to rotate. The rotating member 2114 is connected to the rotating shaft 2112, that is, the rotation of the rotating shaft 2112 can drive the rotating member 2114 to rotate. In this way, the power source 2113 drives the rotating member 2114 to rotate by driving the rotating shaft 2112 to rotate, that is, the power source 2113 drives the rotating member 2114 to rotate.
[0072] The specific type of power source 2113 is not limited. As an example, please refer to Figure 2 , the power source adopts electric motor.
[0073] In some embodiments, the carrier 23 forms a limiting member 231 , and the conveying device 2 includes a limiter 222 disposed on the conveying frame 22 . The limiter 222 has a limiting state connected to the limiting member 231 and a releasing state separated from the limiting member 231 .
[0074] The limiting state means that when the limiter 222 is connected to the limiting member 231, the carrier 23 can be limited on the conveying frame 22. In this way, the stability of the carrier 23 when parked on the conveying frame 22 can be improved. For example, when the power assembly 21 does not drive the carrier 23 to move, the limiter 222 can be in the limiting state, and the carrier 23 can be limited on the conveying frame 22.
[0075] The release state means that when the stopper 222 is separated from the stopper 231, the carrier 23 can be released from the conveyor frame 22, so that the carrier 23 can move on the conveyor frame 22. For example, when the power assembly 21 drives the carrier 23 to move, the stopper 222 is in the release state and does not hinder the carrier 23 from moving on the conveyor frame 22.
[0076] As an example, see Figure 1 and Figure 2 The limiter 222 is located on the cache station 2b, and the limiter 231 is located at one end of the carrier 23 close to the limiter 222. When the carrier 23 reaches the cache station 2b, the limiter 222 can be connected to the limiter 231 to achieve that the carrier 23 is limited on the cache station 2b.
[0077] In some embodiments, one of the limiting member 231 and the limiter 222 is a limiting cylinder, and the other of the limiting member 231 and the limiter 222 is a limiting hole. In the limiting state, the piston rod of the limiting cylinder is inserted into the limiting hole; in the released state, the piston rod of the limiting cylinder is released from the limiting hole. In this way, the limiting and releasing of the carrier 23 on the conveying rack 22 can be achieved through the cooperation of the limiting cylinder and the limiting hole.
[0078] In the limited state, the piston rod of the limit cylinder is inserted into the limit hole, and the limit member 231 is connected to the limiter 222, so that the carrier 23 is limited on the conveying frame 22 and the movement of the carrier 23 on the conveying frame 22 is limited. In the released state, the piston rod of the limit cylinder is inserted into the limit hole, and the limit member 231 is separated from the limiter 222, and the carrier 23 is released from the conveying frame 22, and the movement of the carrier 23 on the conveying frame 22 is not limited.
[0079] The position, number and specific shape of the limiting holes are not specifically limited, as long as they can be connected and separated with the limiting cylinder.
[0080] As an example, see Figure 1 and Figure 2 The limiting member 231 is a limiting hole, and the limiting device 222 is a limiting cylinder. In this way, the deadweight of the carrier 23 can be reduced.
[0081] In some embodiments, at least two cache stations 2b are spaced apart along a first direction, the station 2a to be replaced is located between the two cache stations 2b, and the welding device 1 is located on one side of the station 2a to be replaced along a second direction, wherein the first direction, the second direction and the up and down directions are perpendicular to each other.
[0082] At least two buffer stations 2b are arranged at intervals along the first direction, and the station to be replaced 2a is located between the two buffer stations 2b. In this way, on the one hand, the buffer station 2b and the station to be replaced 2a are on the same straight line, which facilitates the rapid movement of the carrier 23 between the station to be replaced 2a and the buffer station 2b; on the other hand, the carrier 23 can move between the station to be replaced 2a and the two buffer stations 2b along the first direction, that is, the carrier 23 can move to the station to be replaced 2a or the buffer station 2b in both directions along the first direction, which facilitates flexible movement.
[0083] The welding device 1 is located on one side of the workstation 2a to be replaced along the second direction, and the first direction, the second direction and the up-down direction are perpendicular to each other. In this way, the path between the welding device 1 and the workstation 2a to be replaced is simple, which facilitates the transportation of welding tools between the carrier 23 of the workstation 2a to be replaced and the welding device 1.
[0084] Exemplarily, the welding device 1 is located at one side of the workstation 2a to be replaced along the second direction, and the carrier 23 may be provided with a roller group, which may include a plurality of rollers arranged at intervals along the second direction, and the rotation axis of the rollers extends along the first direction. The welding device 1 may be provided with a roller group, which may include a plurality of rollers arranged at intervals along the second direction, and the rotation axis of the rollers extends along the first direction.
