Description

Technical Field

[0001] This invention relates to the field of cold-rolled strip steel joining technology, and more particularly to an automatic tape applicator. Background Technology

[0002] Argon arc spot welding machines are used for strip welding in the cold rolling finishing production line. Due to the unstable welding current of the welding machine, the welding quality is affected, resulting in insufficient weld strength. For example, when the unit is set to low tension strip threading, cracking problems often occur at the weld.

[0003] Furthermore, due to the use of spot welding, welding slag is easily formed during the welding process and adheres to the steel rolls, causing pitting defects on the strip surface. To prevent batch quality accidents on the production line, operators need to clean the welding slag from the welding machine for each roll, and an extra small tail roll needs to be added at the production line exit to facilitate strip surface quality inspection.

[0004] The aforementioned problems and measures not only increase the labor intensity and safety risks for operators, but also significantly reduce the operating efficiency of the production line and product quality. Summary of the Invention

[0005] This application provides an automatic tape application device, which solves the technical problems in the related art where spot welding of strip steel results in limited weld quality, weld slag formation and pitting defects, and the impact of corresponding processing operations on work efficiency.

[0006] This application provides an automatic tape applicator, including a gantry frame, an XYZ three-axis module, and a tape applicator mechanism. The gantry frame is provided with a strip steel moving channel, which includes an overlap area between the tail of the exit strip steel and the head of the inlet strip steel. The XYZ three-axis module is installed on the gantry frame, and the tape applicator mechanism is installed on the Z-axis linear module of the XYZ three-axis module to apply tape to the tail of the exit strip steel and the head of the inlet strip steel.

[0007] In some possible implementations, the adhesive application mechanism includes a base mounted on the Z-axis linear module of the XYZ three-axis module and a component mounted on the base:

[0008] A roll of film, with the tape reel attached to it;

[0009] Guide assembly for winding and discharging the tape and pressing the tape against the surface of the strip moving through the strip channel, the strip including outlet strip and inlet strip; and

[0010] A cutter is used to cut the tape after it has been applied to the surface of the strip.

[0011] In some possible implementations, the adhesive application mechanism also includes a component mounted on the base:

[0012] A pressure roller, the surface of which is configured to press the tape adhered to the strip.

[0013] Along the direction of strip movement in the strip moving channel, the film roll, guide group, cutter and clamping wheel are arranged in sequence.

[0014] In some possible implementations, the guide assembly includes several guide rollers, guide plates, and pressure rollers. The tape unwound from the tape loop passes around the guide rollers and is conveyed to the guide plates. The pressure rollers are positioned opposite the outlet of the guide plates and are configured to move vertically to press the tape exiting the guide plates onto the surface of the strip.

[0015] In some possible implementations, the pressure roller is configured to be driven by a first cylinder.

[0016] In some possible implementations, the clamping wheel is rotatably mounted on the wheel seat, a vertical rod is mounted on the top of the wheel seat, a cylinder seat is provided on the base, the vertical rod passes through the cylinder seat vertically, a limit plate is mounted on the top of the vertical rod, and a spring is sleeved on the vertical rod, with the spring located between the wheel seat and the cylinder seat.

[0017] In some possible implementations, the cutter is configured to be driven by a second cylinder.

[0018] In some possible implementations, the automatic tape applicator is also equipped with a control center to control the XYZ three-axis module and the cutter.

[0019] In some implementation schemes, the control center also controls the front and rear pressure rollers connected to the automatic tape applicator.

[0020] In some possible implementations, the control center is equipped with a touchscreen.

[0021] The beneficial effects of this application are as follows: This application provides an automatic tape-applying device for connecting two strip steels with tape. Specifically, a strip steel moving channel is set in the gantry frame of the device. The strip steel moving channel is used for the movement of the strip steel. Specifically, when two strip steels are transitioning one after the other, an overlap area is formed between the tail of the exit strip steel and the head of the inlet strip steel. This device sets an XYZ three-axis module on the gantry frame and installs the tape-applying mechanism on the Z-axis linear module of the XYZ three-axis module. The XYZ three-axis module realizes the movement of the tape-applying mechanism in the X, Y, and Z directions, and the tape in the tape-applying mechanism is applied to the strip steel. Specifically, the tape is attached to the tail of the exit strip and the head of the inlet strip to connect them. This device uses automatic tape bonding to connect the ends of thin plates, effectively replacing welding. This overcomes the problems of unstable welding current leading to potential weld joint strength defects, and also overcomes the problems of slag formation and pitting defects caused by spot welding. It effectively improves the product quality of the production line, eliminating the need for additional quality inspection of the tail coil. This device can be used in conjunction with a low-tension tape threading control method to significantly improve the production line's operating efficiency and reduce the labor intensity and operational risks for operators.

Detailed Implementation

[0027] This application provides an automatic tape-applying device, which solves the technical problems in related technologies where spot welding of strip steel results in limited weld quality, weld slag formation and pitting defects, and the impact of corresponding processing operations on work efficiency.

[0028] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0029] An automatic tape applicator includes a gantry frame, an XYZ three-axis module, and a tape applicator mechanism. The gantry frame has a strip movement channel, which includes an overlap area between the tail of the exit strip and the head of the inlet strip. The XYZ three-axis module is mounted on the gantry frame, and the tape applicator mechanism is mounted on the Z-axis linear module of the XYZ three-axis module to apply tape to the tail of the exit strip and the head of the inlet strip.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] Please refer to Figures 1 to 3This embodiment discloses an automatic tape applicator, including a gantry frame 100, an XYZ three-axis module 200, and a tape applicator 300. The gantry frame 100 is provided with a strip movement channel (not shown in the figure), which includes an overlap area between the tail of the exit strip and the head of the inlet strip. The XYZ three-axis module 200 is installed on the gantry frame 100, and the tape applicator 300 is installed on the Z-axis linear module of the XYZ three-axis module 200 to apply tape 3211 to the tail of the exit strip and the head of the inlet strip.

[0032] Specifically, the gantry frame 100 of this device is equipped with a strip steel moving channel for moving the strip steel. Specifically, during the transition between two strip steels, an overlap area is formed between the tail of the exit strip steel and the head of the inlet strip steel. In some feasible implementations, during the overlap, the tail of the exit strip steel is located on the lower layer and the head of the inlet strip steel is located on the upper layer. The corresponding adhesive applicator 300 moves from the inlet to the outlet of the strip steel moving channel to complete the adhesive tape application.

[0033] This device uses an XYZ three-axis module 200 mounted on a gantry frame 100, and an adhesive applicator 300 mounted on the Z-axis linear module of the XYZ three-axis module 200. The XYZ three-axis module 200 can move along the X, Y, and Z axes respectively. The adhesive applicator 300 moves in the X, Y, and Z directions via the XYZ three-axis module 200, applying adhesive tape 3211 to the strip steel. Specifically, by utilizing the overlap area formed by the tail of the exit strip steel and the head of the inlet strip steel, adhesive tape 3211 is applied to both the tail of the exit strip steel and the head of the inlet strip steel, thus connecting the tail of the exit strip steel and the head of the inlet strip steel.

[0034] In summary, this device, which uses automatic tape bonding to connect the ends of thin plates, effectively replaces welding, thus overcoming the problems of unstable welding current leading to potential weld joint strength defects, and the problems of slag formation and pitting defects caused by spot welding. This significantly improves product quality on the production line, eliminating the need for additional quality inspections at the tail coil. Furthermore, this device can be combined with a low-tension tape threading control method to significantly improve production line efficiency and reduce operator workload and risks.

[0035] For some possible implementation schemes, please refer to the following: Figure 3 The adhesive applicator 300 includes a base 310 and an adhesive roll 320, a guide assembly 330, and a cutter 340 mounted on the base 310. The base 310 is mounted on the Z-axis linear module of the XYZ three-axis module 200, allowing the adhesive applicator 300 to move in three directions according to the XYZ three-axis module 200, forming a shape similar to... Figure 1 The bonding and arrangement of the film.

[0036] In the adhesive applicator 300, a tape ring 321 is mounted on the outer surface of the tape roll 320. The tape ring 321 is an integrated tape 3211. The tape ring 321 can be replaced manually. The tape 3211 exiting from the tape ring 321 is wound out through the guide group 330. The tape 3211 is wound around the guide group 330, which unfolds the tape 3211. When tape 3211 needs to be bonded, it can be pressed against the surface of the strip steel moving channel. The strip steel here includes the aforementioned exit strip steel and inlet strip steel, realizing the connection between the inlet strip steel and the exit strip steel. After pasting, the tape 3211 is cut by the cutter 340. Specifically, the tape 3211 is cut after it is pasted on the surface of the strip steel.

[0037] The adhesive applicator 300 described above enables the proper arrangement of the adhesive tape, as well as the effective operation of pasting and cutting the strip steel.

[0038] Understandably, this device involves related controls. In some possible implementations, the automatic tape applicator is also equipped with a control center. The control center controls the connection between the XYZ three-axis module 200 and the cutter 340, which is reflected in controlling the multi-directional spatial movement of the tape applicator 300 and controlling the cutter 340 to cut the tape 3211.

[0039] In some possible implementations, the control center also controls the front and rear pressure rollers of the automatic tape applicator. Specifically, when the outlet strip tail and the inlet strip head are overlapped and the tape 3211 is connected after overlap, the front and rear pressure rollers of this device can be controlled to be in a pressed state, so that the relevant strip tail and strip head are in a stable position, which is beneficial to the operation of the subsequent tape applicator 300.

[0040] In some possible implementations, the control center is equipped with a touch screen, through which the travel of the XYZ three-axis module 200 is controlled when connecting strips of different specifications via touch screen input.

[0041] Please refer to Figure 3 The following further defines the adhesive applicator 300.

[0042] In some possible embodiments, the adhesive applicator 300 further includes a pressure roller 350 mounted on the base 310, the surface of the pressure roller 350 being configured to press the adhesive tape 3211 adhered to the strip steel; wherein, as Figure 3As shown, along the strip movement direction of the strip moving channel, the film roll 320, guide group 330, cutter 340, and pressure roller 350 are arranged sequentially. The function of the pressure roller 350 is to press the film 3211 firmly after it is pasted onto the strip surface, and the roller surface of the pressure roller 350 rolls the film 3211 once to strengthen the adhesion between the film 3211 and the strip.

[0043] In some possible implementations, such as Figure 3 As shown, the adhesive application mechanism 300 also includes an advance wheel 360, which is positioned in front of the guide group 330 along the strip movement direction of the strip movement channel. Specifically, when the adhesive application mechanism 300 moves down to the ready state where the adhesive tape 3211 contacts the strip surface, the advance wheel 360 directly contacts the strip surface. As the adhesive application mechanism 300 moves along the strip from front to back, the advance wheel 360 moves in front of the adhesive tape 3211, pressing down on the strip to ensure that the adhesive tape 3211 adheres smoothly and well to the strip surface.

[0044] In some possible implementations, such as Figure 3 As shown, the guide assembly 330 includes several guide rollers 331, a guide plate 332, and a pressure roller 333. The conveyor belt 3211, unfolded from the conveyor belt loop 321, passes around the guide rollers 331 and is conveyed to the guide plate 332. The pressure roller 333 is positioned opposite the outlet of the guide plate 332 and is configured to move vertically to press the conveyor belt 3211 exiting the guide plate 332 onto the surface of the strip steel. Specifically, the guide rollers 331 pull the conveyor belt 3211 of the conveyor belt loop 321 and guide it onto the guide plate 332; the guide plate 332 can be... Figure 3 The vertical cross section shown is triangular in shape. The tape 3211 is led out at the end of the guide plate 332, which is beneficial to limit the spatial position of the tape 3211. By the vertical movement of the pressure roller 333, the tape 3211 from the guide plate 332 is pressed onto the surface of the strip steel, so as to achieve the purpose of the tape 3211 adhering to the surface of the strip steel.

[0045] In some possible implementations, such as Figure 3As shown, the clamping wheel 350 is rotatably mounted on the wheel seat 351. A vertical rod 352 is mounted on the top of the wheel seat 351. The base 310 is provided with a cylindrical seat 353. The vertical rod 352 passes through the cylindrical seat 353 vertically. A limit plate 3521 is mounted on the top of the vertical rod 352. A spring 354 is sleeved on the vertical rod 352 and is located between the wheel seat 351 and the cylindrical seat 353. Specifically, there is no need to actively control the vertical movement of the clamping wheel 350. When preparing to bond, the adhesive applicator 300 moves downward as a whole, which reduces the distance between the cylindrical seat 353 and the wheel seat 351 and causes the vertical rod 352 to move relative to the cylindrical seat 353. The spring 354 is compressed, which presses the clamping wheel 350 on the wheel seat 351 tightly against the surface of the strip steel, including the adhesive tape 3211 against the surface of the strip steel.

[0046] In some possible implementations, such as Figure 3 As shown, the pressure roller 333 is driven by a first cylinder 3331. The extension and retraction of the first cylinder 3331 causes the base 310 of the adhesive applicator 300 to deflect, thereby changing the height of the pressure roller 333. Adjusting the first cylinder 3331 allows the pressure roller 333 to press the adhesive tape 3211 against the surface of the strip steel. Correspondingly, the first cylinder 3331 is rotatably connected to the base 310, and the portion of the base 310 directly connected to the first cylinder 3331 is rotatably connected to other structures.

[0047] In some possible implementations, the cutter 340 is equipped with a second cylinder 341 for driving, enabling rapid cutting of the tape 3211. For example... Figure 3 As shown, the cutter 340 is inclined and specifically positioned below the pressure roller 333, thus allowing the second cylinder 341 and the cutter 340 to have a reasonable arrangement space.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.
