Description

Technical Field

[0001] This invention relates to the field of basket processing equipment technology, and in particular to an automated welding device for basket bottom frames and its welding method. Background Technology

[0002] The metal mesh basket of the present invention includes a mesh basket body and a bottom frame welded to the bottom of the mesh basket body. The mesh basket body is first formed by bending and pressing a bottom mesh sheet and side mesh sheets connected around the bottom mesh sheet. At the four corners, a mating area is formed by overlapping two adjacent side mesh sheets. A robust basket body is formed by welding these mating areas. Subsequently, a reinforcing frame is inserted into and welded to the top opening of the basket body, thus completing the mesh basket body. Although this mesh basket body can be used directly, it is prone to damage under prolonged use due to the direct friction between the bottom mesh sheet and the external environment. Therefore, a bottom support frame needs to be welded to the bottom of the mesh basket body to support the mesh basket body and act as a pad for contact with the external environment, making the mesh basket body more durable. The installation and fixation of the bottom frame at the bottom of the mesh basket involves first initially stamping and fixing the bottom frame at the bottom of the mesh basket, and then welding to more firmly fix the bottom frame to the bottom of the mesh basket. However, at present, the processing step of welding the bottom frame to the bottom of the mesh basket is mainly done manually, resulting in poor production continuity and seriously affecting production efficiency.

Each supporting unit 131 includes a positioning seat 1311 and a spot-welding bottom mold 1312. The positioning seat 1311 is disposed on the base plate 132. The positioning seat 1311 has a recessed receiving groove 41 at each of its two ends and a [missing information - likely a specific type of mold] between its two ends. The bottom mold 1312 is welded, and each lifting support frame 133 is correspondingly fitted onto the positioning seat 1311 of the support unit 131. The two end frames of the lifting support frame 133 are correspondingly accommodated in the receiving grooves 41 at both ends of the positioning seat 1311. The two side frames of the lifting support frame 133 extend to the outside of the positioning seat 1311 and the substrate 132. Each basket conveying station 104 has two lifting drive units 42 on its two sides corresponding to the two side frames of the lifting support frame 133. The lifting drive units 42 support the two side frames of the lifting support frame 133 and drive the lifting support frame 133 to rise and fall relative to the bottom mold 1312.

[0029] For further details, please refer to [link / reference]. Figure 2The lifting drive unit 42 includes a first lifting drive cylinder 421 and a support block 422. The first lifting drive cylinder 421 is disposed inside the platform 111, and the telescopic rod of the first lifting drive cylinder 421 extends to the top surface of the platform 111. The support block 422 is disposed on the telescopic rod of the first lifting drive cylinder 421. The extension and retraction of the telescopic rod of the first lifting drive cylinder 421 drives the support block 422 to rise and fall, thereby supporting the frame edge of the lifting support frame 133 and driving the lifting support frame 133 to rise and fall relative to the welding bottom mold 1312. Several positioning holes are provided on the two side frames of the lifting support frame 133. The support block 422 has a positioning pin protruding from its top corresponding to each positioning hole, so that when the support block 422 supports the frame edge of the lifting support frame 133, each positioning pin is inserted into a corresponding positioning hole.

[0030] Furthermore, the lifting drive unit 42 includes a guide assembly 423, which includes a guide seat and two guide rods. The guide seat is disposed on the top surface of the platform 111. The guide seat has a through hole in its middle for the telescopic rod of the first lifting drive cylinder 421 to pass through, and two through holes at its two ends for the two guide rods to pass through. The top end of each guide rod is connected to the bottom of the support block 422, and the bottom end of the guide rod is inserted into the platform 111 so that the telescopic rod of the first lifting drive cylinder 421 can extend and retract, driving the support block 422 to rise and fall. The stability of the lifting and falling of the support block 422 is improved by the cooperation of the guide seat and the two guide rods.

[0031] For further details, please refer to [link / reference]. Figure 4 , Figure 6The welding mechanism 14 includes several spot welding gun units 141 and pressing units 142. The spot welding gun units 141 are arranged in a rectangular array on the top of the platform 112. Each spot welding gun unit 141 includes a second lifting drive cylinder 1411 and a spot welding gun body 1412. The telescopic rod of the second lifting drive cylinder 1411 drives the spot welding gun body 1412 to rise and fall, so that the spot welding gun body 1412 cooperates with the spot welding bottom mold 1312 to spot weld and fix the bottom frame to the mesh. The bottom of the basket body; the pressing unit 142 is arranged between several welding gun units 141, and includes a third lifting drive cylinder 1421 and a pressing block 1422. The extension and retraction of the telescopic rod of the third lifting drive cylinder 1421 drives the pressing block 1422 to rise and fall. Thus, before the welding gun units 141 weld, the extension and retraction of the telescopic rod of the third lifting drive cylinder 1421 drives the pressing block 1422 to fall, and the pressing block 1422 presses and fixes the mesh basket body to the welding bottom mold 1312. Specifically, the distribution of the welding gun units 141 on the top of the platform 112 corresponds to the position of the bottom frame on the bottom of the basket, so that the inner wall of the bottom of the basket abuts against the welding bottom mold 1312, while the second lifting drive cylinder 1411 drives the welding gun body 1412 to fall, so that the gun head of the welding gun body 1412 abuts against the bottom frame, thereby welding the bottom of the basket to the bottom frame.

[0032] Furthermore, participation Figure 2 , Figure 5 The basket input device 20 includes a conveyor platform 21, a conveying mechanism 22, and a transfer mechanism 23. The conveying mechanism 22 is located on top of the conveyor platform 21 and is used to convey the basket to the basket conveying station 104.

The mounting frame 231 is mounted on top of the conveyor platform 21 and has a transfer track 234 extending horizontally from above one end of the conveyor platform 21 adjacent to the basket conveying station 104 to above the basket conveying station 104. The transfer driving mechanism 232 and the transfer gripper 233 are both located on the transfer track 234, and the transfer driving mechanism 232 can drive the transfer gripper 233 to slide along the transfer track 234, allowing the transfer gripper 233 to convey the basket from the conveying mechanism 22 to the basket conveying station 104. In addition, the basket is conveyed in reverse on the conveying mechanism 22, with the bottom of the basket, which is stamped and fixed with a bottom frame, facing upwards.

[0033] Furthermore, the height of the conveying platform 21 is higher than the height of the mounting platform 11, and the lifting drive unit 42 supports the two side frames of the lifting frame 133. After the lifting frame 133 is raised, the lifting frame 133 is flush with the conveying platform 21, so that the material transfer mechanism 23 can transport the basket onto the lifting frame 133. As the lifting frame 133 descends, the basket is placed on the spot welding bottom mold 1312.

[0034] Furthermore, the material transfer gripper 233 includes a material transfer seat 2331 slidably disposed on the material transfer track 234, a material transfer lifting drive cylinder 2332 disposed on the material transfer seat 2331, and a material transfer frame 2333 disposed on the telescopic rod of the material transfer lifting drive cylinder 2332. The telescopic rod of the material transfer lifting drive cylinder 2332 is vertically downward. The material transfer frame 2333 includes a frame rod 431 connected to the telescopic rod of the material transfer lifting drive cylinder 2332 and two clamping plates 432 disposed opposite to each other at both ends of the bottom surface of the frame rod 431, for the telescopic rod of the material transfer lifting drive cylinder 2332 to extend out. The material transfer frame 2333 holds the basket between the two clamping plates 432.

[0035] Furthermore, in this embodiment, the material transfer drive mechanism 232 includes a material transfer screw 2321 and a servo motor 2322. The material transfer screw 2321 is rotatably mounted on the material transfer track 234, and the material transfer seat 2331 is movably mounted on the material transfer screw 2321 as the material transfer screw 2321 rotates. The servo motor 2322 is mounted at one end of the material transfer frame 2333 to drive the material transfer screw 2321 to rotate.

[0036] Furthermore, the material transfer track 234 is provided with a pressing drive cylinder 441 at one end above the basket conveying station 104. The telescopic rod of the pressing drive cylinder 441 is set vertically downward and a pressing block 442 is provided on it. During the process of the basket being fitted onto the welding bottom mold 1312, the telescopic rod of the pressing drive cylinder 441 extends and retracts, and the pressing block 442 presses the basket against the welding bottom mold 1312.

[0037] For further details, please refer to [link / reference]. Figure 4 The basket output platform 30 has a sloping drop slope 31 at one end of its top adjacent to the basket conveying station 104 and a horizontal picking position 32 at the other end of its top. The highest point of the sloping drop slope is flush with the conveying platform 21, so that when the material transfer gripper 233 conveys the basket from the conveying mechanism 22 to the basket conveying station 104, the basket that has been welded and reinforced on the basket conveying station 104 moves to the drop slope 31 under the push of the material transfer gripper 233 and slides down the drop slope 31 to the picking position 32, so that the processed basket can be taken out.

[0038] Understandably, the welding method of the automated basket bottom frame welding device of the present invention is as follows: The conveyor seat 13, driven by the conveyor drive mechanism 12, reciprocates between the first processing area 101 and the second processing area 102; synchronously with the reciprocating movement of the conveyor seat 13, the basket input device 20 corresponding to the basket conveying station 104 of the first processing area 101 conveys the basket to the support unit 131 located at the basket conveying station 104 when the conveyor seat 13 moves to the first processing area 101, and then to the basket conveying station 104 of the second processing area 102. When the conveyor seat 13 moves to the second processing area 102, the corresponding basket input device 20 conveys the basket to the support unit 131 located at the basket conveying station 104. Simultaneously, each basket input device 20 pushes and conveys the basket, which has undergone spot welding reinforcement, towards the corresponding basket output table 30. During the reciprocating movement of the synchronous conveyor seat 13, when the conveyor seat 13 moves to the first processing area 101 or the second processing area 102, the welding mechanism 14 performs spot welding on the basket on the support unit 131 located at the welding station 103. Specifically, when the conveyor seat 13 moves to the first processing area 101 or the second processing area 102, one support unit 131 is located at the basket conveying station 104, and the other support unit 131 is located at the welding station 103. The support unit 131 located at the basket conveying station 104 is loaded into the basket via the corresponding basket input device 20, and the support unit 131 located at the welding station 103 undergoes spot welding via the welding mechanism 14.

[0039] In summary, the automated welding device for basket bottom frames of the present invention, through the cooperation of the reciprocating welding device 10, the basket input device 20, and the basket output platform 30, allows the conveyor seat 13 to reciprocate between the first processing area 101 and the second processing area 102 under the drive of the conveying drive mechanism 12. When the conveyor seat 13 moves to the first processing area 101 or the second processing area 102, one support unit 131 is located at the basket conveying station 104, and another support unit 131 is located at the welding station 103.
