Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold preparation, in particular to an automatic welding device for glass mold processing. BACKGROUND

[0002] In the field of glass mold processing, welding process is a key link to ensure the quality and performance of the mold. The traditional glass mold welding method mainly relies on manual welding operation on the operation table. Due to the differences in skill level, working state and other factors of welders, the quality of molds welded by different workers is uneven, and even the same worker may cause welding quality fluctuations due to fatigue, mood and other factors when welding at different times. For example, when welding some complex-shaped glass molds, it is difficult for manual welding to ensure the uniformity and consistency of the weld, and defects such as virtual welding and missed welding are likely to occur, affecting the service life of the mold and the forming quality of glass products.

[0003] Secondly, the welding work of the glass mold is usually complicated, and the worker needs to carefully weld each part of the mold. The manual welding speed is relatively slow, which is difficult to meet the needs of large-scale production. In some cases with large order quantity, the low efficiency of manual welding will lead to the extension of production cycle, increase the production cost and reduce the competitiveness in the market.

[0004] With the development of glass molds towards large-scale and complex, the requirements for welding precision and automation degree are becoming higher and higher. The traditional manual welding method has been difficult to meet these new needs. For example, some high-precision glass molds require welding precision to reach microns, which is beyond the reach of manual welding.

[0005] In order to solve the above problems, some automatic welding equipment is used in the market. However, when the existing automatic welding equipment is used for glass mold processing, some equipment has complex structure and high cost, which makes it difficult for small and medium-sized enterprises to bear; some equipment has poor universality and can only be used for welding of specific types or sizes of glass molds, which cannot meet the diversified production needs; some equipment is not accurate enough in positioning and fixing the mold during welding, resulting in unstable welding quality.

DETAILED DESCRIPTION

[0022] In order to better explain the present application, so as to be understood, the following specific embodiments are described in detail in combination with the accompanying drawings.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. As long as the effects of the present application can be achieved, various changes can be made to the embodiments.

[0024] The components in the present application are sequentially connected by the person skilled in the art, and the specific connection and operation sequence should be referred to the working principle below. The detailed connection means is the known technology in the art, and the working principle and process are mainly introduced below.

[0025] As shown in Figure 1 , the present application provides an automatic welding device for glass mold processing, which comprises a machine table 1, a conveying mechanism 2, a lifting device 3 and a welding device 4. The conveying mechanism 2 is arranged on the machine table 1, and the lifting device 3 and the welding device 4 are arranged on the two sides of the conveying mechanism 2 along the conveying direction of the conveying mechanism 2.

[0026] In the present embodiment, as shown in Figure 2 , the conveying mechanism 2 comprises a conveying belt 21 arranged along the length direction of the machine table 1, and a plurality of placement tables 22 for placing the processed molds are arranged on the conveying belt 21 at intervals. Spaces are left between the adjacent two placement tables 22 to form vacant sections 23.

[0027] In the implementation, the mold to be welded is placed on the placement table 22 and conveyed by the conveying belt 21 to the finished product station. During the conveying process, it is stopped at the lifting device 3 and the welding device 4, and the mold to be welded is lifted by the lifting device 3 to separate from the placement table 22. The conveying belt 21 continues to advance one station, so that the lifting device 3 holds the mold to be welded suspended at the vacant section 23 and placed on the welding device 4 for welding. After welding is completed, the lifting device 3 holds the welded mold again, the conveying belt 21 continues to advance one station, the lifting device 3 lowers to place the welded mold on the next placement table 22, and the lifting device 3 and the welding device 4 are reset. The conveying belt 21 continues to advance and repeats the above working process to form a pipeline type automatic welding operation.

[0028] In the present embodiment, as shown in Figure 3 , the lifting device 3 comprises a first advancing mechanism 33, a lifting mechanism 32 and a lifting frame 31. The lifting mechanism 32 is arranged at the moving end of the first advancing mechanism 33 and can be close to or away from the conveying mechanism 2 by the first advancing mechanism 33. The lifting frame 31 is arranged on the lifting mechanism 32 and moves up and down along the vertical direction of the lifting mechanism 32.

[0029] For example, during implementation, the first propulsion mechanism 33 pushes the lifting mechanism 32 and the lifting frame 31 to the conveyor belt 21, so that the lifting frame 31 is located below the mold to be welded. At this time, the lifting mechanism 32 performs lifting and subsequent lowering operations, so that the lifting frame 31 lifts the mold to be welded away from the placement platform 22 and places the welded mold on the next placement platform 22.

[0030] In this embodiment, as Figure 5 As shown, the first propulsion mechanism 33 includes two first base plates 332, two first guide rails 333, a second propulsion frame 334, and a second propulsion hydraulic cylinder 331. The two first base plates 332 are fixed opposite to each other on the machine base 1. The two first guide rails 333 are respectively mounted on each first base plate 332. The second propulsion frame 334 is "gate" shaped, with its two long ends fixed to the moving ends of the two first guide rails 333. The output end of the second propulsion hydraulic cylinder 331 is fixed at the short end of the second propulsion frame 334. When the second propulsion hydraulic cylinder 331 propels forward and backward, it pushes the lifting frame 31 to insert into or detach from the mold after welding.

[0031] In this embodiment, as Figure 3 As shown, the lifting mechanism 32 includes a guide frame 321 and a first propulsion hydraulic cylinder 322. (As...) Figure 4 As shown, four guide frames 321 are preferably arranged in pairs, on either side of the first propulsion hydraulic cylinder 322, to ensure the stability of the lifting frame 31 when the first propulsion hydraulic cylinder 322 moves up and down. Specifically, the guide frame 321 includes two opposing frame plates 3211, with a clamping cavity 3213 formed between the two frame plates 3211, and the tail rod 313 is inserted into the clamping cavity 3213; the output end of the first propulsion hydraulic cylinder 322 is fixed on the tail rod 313.

[0032] Furthermore, the inner walls of both support plates 3211 are longitudinally provided with guide grooves 3212, and the side wall of the tail rod 313 is provided with a slider 314, which is slidably connected in the guide grooves 3212.

[0033] For example, when the first propulsion hydraulic cylinder 322 propels and retracts, it drives the guide frame 321 to move up and down in the clamping cavity 3213, and the slider 314 slides in the guide groove 3212 to guide the tail rod 313.

[0034] like Figure 6The lifting frame 31 in the embodiment includes a fixedly connected insertion frame and tail rod 313, and a guide frame 321 and a first pushing hydraulic cylinder 322 are connected to the tail rod 313. The insertion frame includes a first pushing frame 311, and lifting frames 312 are arranged at both ends of the first pushing frame 311. When the lifting frame 31 lifts the mold, the lifting frames 312 are in contact with the portions of the placing table 22 protruding on both sides of the bottom of the mold.

[0035] In the embodiment, as shown in Figure 7 The welding device 4 includes a second pushing mechanism 46, a rotating mechanism 44, a column 41, a pressing mechanism 42 and a sliding welding mechanism 43. The moving end of the second pushing mechanism 46 is provided with a table plate 45, the rotating mechanism 44 is arranged on the table plate 45, and the mold to be welded is arranged on the rotating mechanism 44. The column 41 is fixed to the table plate 45 and located on one side of the rotating mechanism 44, and a cross beam is fixed to one side of the top of the column 41.

[0036] As shown in Figure 8 The pressing mechanism 42 is arranged on the cross beam and suspended above the rotating mechanism 44. The pressing mechanism 42 includes a pressing hydraulic cylinder 421, and the output end of the pressing hydraulic cylinder 421 penetrates through the cross beam and is rotatably connected with a pressing plate 422. In the implementation, the pressing hydraulic cylinder 421 drives the pressing plate 422 to descend and abut on the mold, so that the mold is pressed and fixed on the rotating mechanism 44.

[0037] Further, when the mold is welded on the rotating mechanism 44, the pressing plate 422 can rotate with the rotation of the rotating mechanism 44, so as to adapt to the movement of the mold.

[0038] As shown in Figure 8 The sliding welding mechanism 43 is arranged on the column 41. The sliding welding mechanism 43 includes a first electric linear guide rail 431 and a second electric linear guide rail 432. The first electric linear guide rail 431 is fixed vertically on the inner wall of the column 41, and the second electric linear guide rail 432 is fixed transversely on the moving end of the first electric linear guide rail 431. The moving end of the second electric linear guide rail 432 is provided with a welding gun 433. The welding gun 433 is driven to move transversely and longitudinally by the first electric linear guide rail 431 and the second electric linear guide rail 432, and the automatic welding of multiple points of the mold to be welded is realized by cooperating with the rotation of the mold by the rotating mechanism 44.

[0039] As shown in Figure 7As shown, the second propulsion mechanism 46 includes a second base plate 461, a second guide rail 462, and a third propulsion hydraulic cylinder 463. The second base plate 461 is fixed on the machine table 1, the second guide rail 462 is fixed on the second base plate 461, the plate 45 is fixed on the moving end of the second guide rail 462, and the output end of the third propulsion hydraulic cylinder 463 is fixed on the plate 45. When the third propulsion hydraulic cylinder 463 is pushed back and retracted, the plate 45 and the components thereon are moved forward and backward on the second guide rail 462 to drive the rotating mechanism 44 to approach or move away from the conveyor belt 21.

[0040] In this embodiment, as shown in Figure 9 and Figure 10 As shown, the rotating mechanism 44 includes a positioning body 446, a rotating table 447, a driving shaft 442, and a driven shaft 443. The positioning body 446 is fixed on the plate 45, the inner side of the positioning body 446 is provided with a pedestal 444, and the inside of the pedestal 444 is hollow. The driving shaft 442 and the driven shaft 443 are rotationally connected by a belt 441. The driving shaft 442 is rotationally connected to the plate 45 and is connected to a motor 445. The motor 445 is fixed on a fixed object, such as a motor seat, which is fixed on the plate 45. The driven shaft 443 is arranged on the pedestal 444, the rotating table 447 is arranged on the driven shaft 443, and is located above the pedestal 444. When the driven shaft 443 is rotated, the rotating table 447 is rotated on the pedestal 444.

[0041] The device realizes automatic feeding, positioning, welding, and discharging of the glass mold through a pipeline type automatic operation process combined with the cooperation of the lifting device 3 and the welding device 4. The specific working principle is as follows: After the mold to be welded is placed on the placing table 22 of the conveying mechanism 2, the placing table is moved along the length direction of the machine table 1 by the conveyor belt 21, and the mold is conveyed to the welding station and then paused. The space section 23 between the adjacent placing tables 22 on the conveyor belt 21 is reserved for the operation of the lifting device 3 and the welding device 4 to ensure that the mold does not interfere with the conveyor belt during transfer; The lifting device 3 approaches the mold: the second propulsion hydraulic cylinder 331 of the first propulsion mechanism 33 pushes the second propulsion frame 334 to slide along the first guide rail 333, drives the lifting mechanism 32 and the lifting frame 31 to move transversely, and makes the lifting frame 312 of the lifting frame accurately inserted into the lower side of the mold to be welded; The mold is lifted off the conveying mechanism 2: the first propulsion hydraulic cylinder 322 of the lifting mechanism 32 is elongated, drives the lifting frame 31 to vertically rise along the guide groove 3212 of the guide frame 321 through the tail rod 313, and lifts the mold away from the placing table 22; The conveyor belt 21 gives way: the conveyor belt 21 moves forward by one station, so that the mold held by the lifting frame 31 is suspended above the space section 23, thereby providing space for the mold to be transferred to the welding device 4; Mold placement to welding device 4: the second propulsion mechanism 46 of the welding device 4 starts, the third propulsion hydraulic cylinder 463 pushes the table plate 45 to move along the second guide rail 462 to the conveying mechanism 2, so that the rotating mechanism 44 of the rotating table 447 is close to the mold; the lifting frame 31 is lowered, and the mold is placed on the rotating table 447; Mold pressing: the lower pressing hydraulic cylinder 421 of the pressing mechanism 42 is elongated, the pressing plate 422 is pushed down and pressed to fix the mold on the rotating table 447, and the pressing plate 422 can rotate synchronously with the rotating table 447 to avoid interference with welding; Welding device 4 reset: the third propulsion hydraulic cylinder 463 of the second propulsion mechanism 46 is retracted, the table plate 45 and the rotating mechanism 44 are driven away from the conveying mechanism 2, and it is ensured that the welding process does not interfere with the conveying belt 21; Mold rotation: the motor 445 of the rotating mechanism 44 is started, the driving shaft 442 and the driven shaft 443 are driven to rotate through the belt 441, the rotating table 447 and the mold are synchronously rotated, and the welding position switching of the mold at different angles is realized; Multi-dimensional movement of welding gun 433: the first electric linear guide rail 431 of the sliding welding mechanism 43 controls the vertical lifting longitudinal movement of the welding gun 433 along the column 41, and the second electric linear guide rail 432 controls the transverse movement of the welding gun 433; both cooperate with the rotation of the mold to realize accurate welding of each point of the mold and ensure that the welding seam is uniform and consistent; after welding, the lower pressing hydraulic cylinder 421 of the pressing mechanism 42 is retracted, and the pressing plate 422 is lifted to separate from the mold; Mold transfer back to conveying mechanism 2: the second propulsion mechanism 46 again drives the table plate 45 to approach the conveying mechanism 2, and the lifting frame 31 is lifted to hold the welded mold; the pressing mechanism 42 is loosened, and the lifting frame 31 lifts the mold away from the rotating table 447; Mold placement back to conveying belt 21: the conveying belt 21 moves forward by one station, the lifting frame 31 is lowered, and the mold is placed on the next placement table 22; the lifting device 3 and the welding device 4 are reset, and the next mold to be welded is entered into the station, and the above process is repeated.

[0042] Through the above steps, the device realizes the full-automatic assembly line operation of "conveying, transferring, fixing, welding and resetting" of the glass mold, greatly improves the welding precision and efficiency, and adapts to the processing needs of molds of different types and sizes.
