Description

Technical Field

[0001] The invention relates to the technical field of automatic cutting and splicing equipment, and in particular to a method for energy-saving splicing of strip-shaped products using intelligent splicing equipment. Background Art

[0002] In the field of electronics industry, in the process of continuous roll-type surface electroplating treatment production line in strip products, first of all, the surface treatment materials should be continuously introduced into the surface treatment production line through the unwinding machine. With the rapid development of the electronics industry, many continuous metal electronic products are constantly developing towards miniaturization and micro-miniaturization, and the processing speed requirements of the continuous surface treatment production line are getting higher and higher. However, in the actual surface treatment production, the tail end of the previous roll of the strip product and the head end of the next roll are connected. The connection operation is divided into two processes: cutting and splicing. Cutting is divided into manual cutting and mechanical cutting, and splicing is also divided into manual splicing and mechanical splicing.

[0003] Manual cutting refers to manually cutting the tail end of the previous roll and the head end of the next roll according to the process requirements. Manual cutting can easily result in poor cutting accuracy, affecting subsequent splicing and further affecting the quality of splicing. Manual splicing includes manual rivets, wire binding and tape bonding. Not only are the operations complicated and time-consuming, but the joints are also not firm. In addition, the above-mentioned splicing methods will make the product joints too thick, causing the strip products to scrape against equipment during transportation, causing the product to deform and resulting in downtime. Therefore, splicing methods such as manual rivets, wire binding and tape bonding require grinding of the joints, reducing production efficiency.

[0004] Existing connection equipment can only use positioning pins to fix products for connection. When changing products, the fixture must be replaced, resulting in too long downtime for line change, which affects the efficiency of the production unit. If the line change time is too long, the connection will not be worth the cost. In addition, existing welding uses contact welding such as ultrasonic or resistance welding. The welding head is easily adhered to the product and the product needs to be peeled off. The same contact welding also requires grinding of the product connection. Summary of the invention

During the operation, only one layer of the material tray device 1-2 is moved to the working position for docking, and the material tray devices 1-2 on other layers are used for material preparation. After the unwinding of the unwinding tray 1-6 on the working position is completed, the material tray devices 1-2 on other layers are moved up or down to the working position to continue the docking, which makes material replacement convenient and improves production efficiency.

[0087] The operation of the discharge module 1 specifically includes the following steps:

[0088] Step (1), start the tray changing cylinder 1-18 to make the tray platform 1-5 pop out;

[0094] Step (7), when the head material and the tail material need to be butt-welded and stack-welded, start the stack-welding machine cylinder 1-7 of the material discharge unit located at the working position, and the piston rod of the stack-welding machine cylinder 1-7 drives the fixed plate 1-23 to move, so as to drive the clamping jaw mounting plate 1-8 to move forward and backward, and then adjust the position of the material preparation clamping jaw 1-10 in the front and rear directions, thereby adjusting the position of the head material; when the head material and the tail material need to be butt-welded, the head material clamped on the material preparation clamping jaw 1-10 is moved to the same plane as the tail material of the next workstation; when the head material and the tail material need to be stack-welded, the head material clamped on the material preparation clamping jaw 1-10 is moved to the back or front of the tail material, so that the two ends of the head material and the tail material partially overlap;

[0095] Step (8), turning on the paper collection torque motor 1-13, the paper pressing belt tray 1-14 starts to reel in the release paper, thereby driving the unwinding tray 1-6 to unwind the tape until the terminal tape on the unwinding unit at the working position is unwound;

[0096] Step (9), start the upper and lower servo motors 1-20, so that the plurality of unloading units move up and down synchronously along the slide rails 1-21, move the unloading units located at other layers to the working position, and repeat steps (7) to (8) to perform the docking action;

[0097] Step (10), after step (9), the unloading unit of the empty layer is replaced, and the operator starts the tray changing cylinder 1-18 of the empty layer to make the tray platform 1-5 of the layer pop out, and removes the empty unloading tray 1-6 and the paper pressing belt tray 1-14 filled with release paper;

[0098] Step (11), repeating steps (2) to (4) on the unloading unit of the empty layer to complete the material replacement work.

[0099] The function of unloading module 1 is:

[0100] (1) A plurality of unloading units are arranged on the servo control device 1-1 so as to be movable up and down, so as to switch the material trays, and then the material tray platform 1-5 is slidably connected with the connecting mechanism 1-4, so that the material tray platform 1-5 can be easily pulled out when the material tray is changed, which makes the operation more convenient and facilitates human-machine interaction;

[0101] (2) The clamping jaw assembly is controlled to move forward and backward by the stack welding machine cylinder 1-7, and has dual function switching between butt welding and stack welding to meet the connection requirements of different material strips.

[0102] like Fig.17 The waste clamping module 3 shown includes a rotary grabbing mechanism and a lifting mechanism, the lifting mechanism is arranged on the welding mobile platform 7, and the rotary grabbing mechanism is installed on the top rod of the lifting mechanism;

The waste grabbing assembly is arranged on the output shaft of the rotary feeding cylinder 3-2. The output shaft of the rotary feeding cylinder 3-2 is arranged along the Z direction. The lifting mechanism has a lifting end that moves along the Z direction. The lifting end includes a pressing plate 3-3. The pressing plate 3-3 is arranged above the product 6 and can be operably pressed against the product 6. The rotary feeding cylinder 3-2 is arranged on the lifting end.

[0104] The welding mobile platform 7 drives the lifting mechanism to move along the X direction, so that only one set of waste clamping modules is used to realize the waste grabbing of the head and tail of the product 6 during the cutting and welding process; when the lifting end moves along the Z direction, it drives the rotating material taking cylinder 3-2 to move along the Z direction, and the waste grabbing assembly is driven by the rotating material taking cylinder 3-2 to clamp the head or tail of the material belt, and at the same time, the pressure plate 3-3 can be pressed on the top of the product 6 to play a material pressing role and achieve a limiting effect, and the two effects of grabbing and pressing are achieved through one action.

[0107] The rotary material taking cylinder 3-2 uses the Airtac cylinder ACKL25x180, which can control the scrap grabbing assembly to rotate to the top of the scrap placement and to the place where the scrap is clamped. The scrap clamping cylinder 3-6 uses the Airtac cylinder HFY10_DMSG-2, which is used to control the opening and closing of the scrap clamp 3-7.

[0108] The lifting mechanism also includes a lifting linear guide rail 3-1 and a stepper motor 3-8 that drives the lifting linear guide rail 3-1 to work. The lifting end is a lifting plate 3-9 that lifts up and down along the lifting linear guide rail 3-1. The stepper motor 3-8 is used to control the lifting plate 3-9 to move along the Z direction. The stepper motor 3-8 can accurately move the lifting plate 3-9 to the target position according to the input pulse signal, thereby ensuring that the pressing plate 3-3 can accurately press on the material belt and ensure that the waste clamp 3-7 accurately moves to the grabbing position. The pressing plate 3-3 is set on the other side of the lifting plate 3-9. The pressing plate 3-3 is extended in a protruding direction away from the lifting plate 3-9 and can be operably pressed against the product 6. The rotary material-collecting cylinder 3-2 is set on the lifting plate 3-9.

[0109] The stepper motor 3-8 uses the model of the Skylark micro slide SH20-L5-S50, which controls the lifting end through the input pulse signal. When the pulse signal is OFF, the lifting end moves to the top of the fixed component. When the pulse signal is ON1, the lifting end moves to the top of the product 6 and rests on the product 6 for pressing. When the pulse signal is ON2, the lifting end moves to slightly above the product 6 to play a limiting role.

[0110] As the lifting plate 3-9 descends, the pressing plate 3-3 and the rotary material-collecting cylinder 3-2 are simultaneously driven downward, and the waste clamp 3-7 connected to the other end of the rotary material-collecting cylinder 3-2 also descends accordingly. The pressing plate 3-3 can be used to press the material, achieving both the material grabbing and material pressing effects through one action.

[0111] The functions of the waste clamping module 3 are as follows:

[0112] (1) The lifting mechanism is driven to move along the X direction by the welding mobile platform 7, so that only one set of waste clamping modules can be used to capture the waste of the product 6 head and tail materials during the cutting and welding process;

[0113] (2) When the lifting end moves along the Z direction, it drives the rotary material picking cylinder 3-2 to move along the Z direction, and the rotary material picking cylinder 3-2 rotates to drive the waste material grabbing assembly to clamp the head or tail of the material belt. At the same time, the pressure plate 3-3 can be pressed on the top of the product 6 to play a role in pressing the material and achieve a limiting effect. The two effects of grabbing and pressing the material are achieved through one action.

If the product is butt welded together, the camera assembly detects whether the weld is completed; if it is stack welding, the tail material of the previous product is driven to the left by the welding mobile platform 7, and the stack welding machine cylinder 1-7 pushes the head material forward first. After the tail material is in place, the stack welding machine cylinder 1-7 retracts, so that the head material and the tail material overlap to form a weld, the light source 2-5 descends, and the welding clamp 2-7 and the light blocking cylinder 2-9 rise at the same time, the welding clamp 2-7 clamps the weld, and the gap is cut from the welding clamp 2-7 to stack the two materials into one. The camera assembly detects whether the weld is completed.
