Description

Technical Field

[0001] The utility model relates to the technical field of coil material feeding, in particular to a coil material continuous feeding machine. Background Art

[0002] The pole of a new energy battery refers to the positive and negative poles in the battery, which are used to store and release electrical energy. The pole is one of the most important components of a battery, directly affecting the performance, cycle life and safety of the battery. In the process of preparing the pole, copper strips are needed in the copper-aluminum composite material used for the pole, and the copper strips are generally prepared in rolls. Therefore, in the copper strip processing, a feeder is needed to transport the rolled copper strips forward.

[0003] The current feeding machine used for conveying copper strip rolls needs to replace a new copper strip roll after each roll is conveyed, and during the replacement process, the current feeding machine generally needs to pause the entire equipment, and then start the equipment again after the copper strip roll is placed in. Moreover, each roll of copper strip roll has a large overall weight, and it takes a long time to stop the machine for replacement, which wastes time and leads to low efficiency in the feeding and conveying process of the copper strip roll. Utility Model Content

[0004] The utility model aims to solve the problem of low efficiency of copper strip coils in the prior art during feeding and conveying, and proposes a coil continuous feeding machine which can realize continuous production without stopping the machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A continuous coil feeder, comprising a machine base, wherein one vertical side surface of the machine base is provided with:

[0007] At least two copper strip rolls, including a first copper strip roll and a second copper strip roll, the two copper strip rolls are installed at the bottom of one end of the machine base; one of the two copper strip rolls is a copper strip roll being fed, and the other is a copper strip roll waiting for feeding;

[0008] A U-shaped frame, the U-shaped frame is fixedly installed at the upper end of the middle of the machine base, and a copper strip detection member for detecting the position of the copper strip head of the copper strip coil waiting for feeding is arranged on the U-shaped frame;

[0009] Two guide rollers, which are staggered up and down and located between the U-shaped frame and the copper strip roll, and the copper strips of the two copper strip rolls are respectively conveyed on the two guide rollers;

[0010] A waiting alternating component, wherein the waiting alternating component is arranged between the guide roller and the U-shaped frame;

[0011] The welding mechanism comprises a welding table and a welding assembly. The welding table is located on the side of the U-shaped frame facing away from the copper strip roll. Two welding clamps for clamping the copper strips at both ends of the top surface of the welding table are arranged above the welding table. A moving docking assembly for clamping and moving the copper strips is arranged between the welding table and the waiting alternating assembly. A discharging roller is arranged on the side of the welding table facing away from the U-shaped frame. The welding assembly is located directly above the welding table and welds and fixes the two closely butted copper strips on the welding table.

[0012] A lifting and buffering assembly includes a pressure rod and a motor that drives the pressure rod to lift and lower. The mounting seat of the pressure rod is connected to the chain of the motor, and the mounting seat can move vertically up and down on the slide rail as the motor rotates forward or reversely. In addition, the mounting seat of the pressure rod is also connected to a counterweight through a wire that passes around a pulley. The function of the counterweight is to offset the gravity of the pressure rod and the mounting seat and reduce the load on the motor. When a counterweight is provided, the requirements for the motor are reduced because it only needs to overcome the resistance between the mounting seat and the slide rail. When the pressure rod descends, it pulls down the copper strip between the discharge roller and the second guide roller for pre-storage. When the tail of the copper strip at the welding mechanism is clamped, the pressure rod rises to restore the normal feeding of the copper strip. Specifically, the lifting and buffering assembly is located on the side of the discharge roller that faces away from the welding table.

The copper strip head and the copper strip tail which are respectively pressed by the first pressing member and the second pressing member on the welding table are welded together by the welding assembly. During the welding process, the copper strip cached by the lifting and lowering cache assembly starts to continue to supply the copper strip material during the process of the pressure rod rising. After the welding is completed, the two pressing members release the copper strip, and the production line resumes normal feeding. At this time, the motor drives the pressure rod to descend and pre-store the copper strip material again for the next welding. At the same time, the used copper strip roll on the support frame is replaced with a new copper strip roll as a new copper strip roll waiting for feeding, and the previous copper strip roll waiting for feeding automatically becomes a copper strip roll being fed.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0043] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0044] Reference Figure 1-Figure 4 A continuous coil feeding machine includes a machine base 1, and one vertical side of the machine base 1 is equipped with: two copper strip coils 2, a U-shaped frame 3, two guide rollers 11, a waiting alternating component 6, a welding table 7, a lifting buffer component 13 and a welding component 4.

[0045] The two copper strip rolls 2 include a first copper strip roll 21 and a second copper strip roll 22. Figure 1It can be seen that at this time, the first copper strip roll 21 is used as the copper strip roll being fed for production feeding, and the second copper strip roll 22 is used as the copper strip roll waiting for feeding. The two copper strip rolls 2 are installed at the bottom of one end of the machine base 1, that is, the copper strip rolls 2 are placed on the support frame on the machine base 1 for the copper strip rolls 2 to be installed, so as to fix the position of the copper strip rolls 2, and at the same time, each copper strip roll 2 is driven by a motor to rotate and discharge. The U-shaped frame 3 is fixedly installed at the upper end of the middle part of the machine base 1. The U-shaped frame 3 is provided with a copper strip detection part 5 for detecting the position of the copper strip head on the second copper strip roll 22. The copper strip detection part 5 has two, the first copper strip detection part 51 and the second copper strip detection part 52. Since the roles of the two copper strip rolls 2 will change at different times, the working status of the two copper strip detection parts 5 will change with the role of the copper strip roll waiting for feeding in the two copper strip rolls 2. Only when the connection is required, the copper strip detection part 5 corresponding to the copper strip roll waiting for feeding will work. The two end legs of the U-shaped frame 3 are vertically fixed on the side of the machine base 1, and the copper strip detection component 5 is installed in the vertical middle of the U-shaped frame 3 corresponding to the position of the waiting alternating component 6. The two guide rollers 11 are staggered up and down and are located between the U-shaped frame 3 and the copper strip roll 2. The two guide rollers 11 convey the copper strips of the two copper strip rolls 2 respectively to avoid interference with the overall equipment during the copper strip conveying. The waiting alternating component 6 is arranged between the guide roller 11 and the U-shaped frame 3, and the waiting alternating component 6 is used to press the copper strip head of the copper strip roll waiting for feeding. The welding table 7 is located on the side of the U-shaped frame 3 facing away from the copper strip coil 2. Two welding clamps 8 are arranged above the welding table 7 to clamp the copper strips at both ends of the top surface of the welding table 7. The two copper strips to be welded are clamped to avoid quality problems such as welding deviation caused by shaking and jittering during welding. A mobile docking component 9 is arranged between the welding table 7 and the waiting alternating component 6 to clamp and move the copper strip. The mobile docking component 9 clamps the copper strip head of the copper strip coil waiting for feeding pressed on the waiting alternating component 6 and then transports it to the welding table 7. A discharging roller 12 is arranged on the side of the welding table 7 facing away from the U-shaped frame 3 for backward transportation at the beginning or after docking. Figure 4 and Figure 5The lifting and buffering assembly 13 includes a pressure rod 136 and a motor 134. The mounting seat 135 of the pressure rod 136 is connected to the chain of the motor. With the forward or reverse rotation of the motor 134, the mounting seat 135 can move vertically up and down on the slide rail 137. In addition, the mounting seat 135 of the pressure rod 136 is also connected to the counterweight 131 through the line 133 bypassing the pulley 132. When the pressure rod 136 descends, it pulls down the copper strip between the discharge roller 12 and the second guide roller 14 for pre-storage. When the tail of the copper strip at the welding mechanism is clamped, the pressure rod 136 rises to restore the normal feeding of the copper strip. The lifting and buffering assembly 13 is located on the side of the discharge roller 12 facing away from the welding table 7. The second guide roller 14 is provided on the side of the lifting and buffering assembly 13 facing away from the welding table 7. The second guide roller 14 is horizontal with the discharge roller 12, and the lifting and buffering assembly 13 conveys the copper strip sent out by the discharge roller 12 to the second guide roller 14 and pre-stores a part of the copper strip. It can be seen that the lifting buffer assembly 13 mainly increases the distance between the contact position between the pressure rod 136 and the copper strip and the discharge roller 12 and the second guide roller 14 by moving the pressure rod 136 downward. Figure 1 In the middle, the lifting buffer assembly 13, the discharging roller 12, and the second guide roller 14 form a triangular structure during pre-storage, and the straight-line distance between the three becomes larger than when they are horizontal. Therefore, the length of the pre-storage can be calculated, and then according to the conveying speed, the time when the pre-storage material is used up can be obtained, which is the maximum time for the two copper strips 2 to be docked. The welding assembly 4 is located directly above the welding table 7, and welds and fixes the two copper strips that are closely docked on the welding table 7;

[0046] The copper strips on the two copper strip rolls 2 pass through two guide rollers 11 respectively. The copper strips on the first copper strip roll 21 pass through the temporarily non-working waiting alternating component 6 and the welding table 7, and then pass through the discharging roller 12 to the pressure rod 136 of the lifting cache component 13 for pre-storage and discharge. The copper strip head on the second copper strip roll 22 is manually loaded to the waiting alternating component 6 before the first copper strip roll 21 is used up. The second pressure piece 63 presses the copper strip head on the U-shaped support plate 61, and then is clamped by the moving docking component 9 at the position of the waiting alternating component 6 and sent into the welding table 7 to dock with the copper strip tail of the first copper strip roll 21 and welded into one through the welding component 4. At the same time, during the welding process, the pressure rod 1369 of the lifting cache component 13 rises to release the pre-stored copper strip material. After the welding is completed and the first clamping piece 81 and the second clamping piece 82 release the copper strip, the pressure rod 136 drops again to pre-store the copper strip material for the next welding. In the utility model, two first guide rollers 10 supporting the copper strip of the first copper strip roll 21 are installed above the first copper strip roll 21 , and the two first guide rollers 10 are horizontally arranged and located above the guide roller member 11 .

[0047] Working process:

[0048] First, the first copper strip roll 21 is fed normally, and the copper strip material is pre-stored at the lifting buffer assembly 13. The second copper strip roll 22 is used as the copper strip roll waiting for feeding. The copper strip head is manually fed to the waiting alternating assembly 6, and then clamped by the mobile docking assembly 9. An extra section of the copper strip head should be left for the mobile docking assembly 9 behind to be clamped and pulled to the welding table 7. The extra section is detected by the copper strip detection component 5. The copper strip detection component 5 shrinks after detecting the copper strip head, which will not affect the feeding of the copper strip. When the first copper strip roll 21 is almost used up, it is detected by a sensor (such as an infrared detector) before it is used up. Once the tail of the copper strip is detected, the copper strip tail of the first copper strip roll 21 is clamped by the welding clamping component 8 at the welding position so that the copper strip tail is just at the welding position (for the detection scheme of the copper strip tail, an infrared detector can be set on the welding assembly. When it is detected that there is no copper strip under the welding assembly, the copper strip tail is When the copper strip is about to reach the second clamping piece 82, the tail of the copper strip is immediately clamped by the second clamping piece 82). At the same time, the mobile docking component 9 pulls the copper strip head of the second copper strip roll 22 to the connection point, and the copper strip head of the second copper strip roll 22 is sent to the welding position and is clamped by the first clamping piece 81. At this time, the welding component 4 detects the copper strip head of the second copper strip roll 22 and welds the head and tail of the two rolls of copper strip. During the welding process, the pressure rod 136 of the lifting and buffering component 13 slowly rises under the drive of the motor 134, and the pre-stored copper strip can be supplied to the production line for continued production. In this process, the copper strip tail is clamped during welding and cannot be fed normally. The motor 134 of the lifting and buffering component 13 drives the pressure rod 136 to move upward, and the pre-stored copper strip is continuously transported forward to continue feeding. After the welding is completed, the motor 134 drives the pressure rod 136 to continue to move downward for the second round of pre-storage for use in the next connection.

[0049] The guide roller member 11 includes a first guide roller 111 and a second guide roller 112 from top to bottom. The copper strip on the first copper strip roll 21 passes through the first guide roller 111 after passing through the two first guide rollers 10, and the second copper strip roll 22 directly passes through the second guide roller 112. This avoids the problem of the copper strips on the two copper strip rolls 2 affecting each other during transportation.

[0050] Reference Figure 5 and Figure 7 The waiting alternating component 6 includes a U-shaped support plate 61 vertically fixed on the machine base 1 and a first pressing piece 62 and a second pressing piece 63 located on the upper and lower sides of the U-shaped support plate 61. The first pressing piece 62 and the second pressing piece 63 can be pushed by a cylinder to press the copper strip. The first pressing piece 62 and the second pressing piece 63 only work when connection is required. When working, when the first pressing piece 62 or the second pressing piece 63 presses the copper strip, the end of the copper strip passes through the U-shaped support plate 61 to the position of the copper strip detection piece 5. The copper strip detection piece 5 includes a first detection piece 51 and a second detection piece 52 arranged at the upper and lower sides, such as Figure 7As shown, the first detection member 51 is located between the U-shaped support plate 61 and the first pressing member 62. The first copper strip roll 21 is feeding normally, and the first detection member 51 does not need to work. Only when the copper strip tail of the first copper strip roll 21 is detected, the second pressing member 63 presses the copper strip, and the second detection member 52 detects the copper strip head position of the second copper strip roll 22. Figure 7-Figure 8 The first detection member 51 and the second detection member 52 both include a material blocking cylinder 511 fixed on the U-shaped frame 3, an L-shaped baffle 512 installed at the end of the material blocking cylinder 511, and a detection sensor 513 installed between the upper and lower ends of the L-shaped baffle 512. The L-shaped baffle 512 is horizontally pushed to the front of the copper strip by the material blocking cylinder 511 and the end position of the copper strip is detected by the detection sensor 513. The L-shaped baffle 512 can prevent the copper strip from extending too long and block the copper strip at the L-shaped baffle 512. At the same time, the detection sensor 513 is an optical fiber sensor. When the copper strip enters between the transmitting end and the receiving end of the optical fiber sensor, the copper strip is detected at this time, and the controller of the loader drives the corresponding cylinder of the first pressing member 62 or the second pressing member 63 to work to press the copper strip.

[0051] Reference Figure 5-Figure 6 and Figure 9-10The welding table 7 includes a welding platform plate 71 vertically fixed to the side of the machine base 1 and a welding platform cover plate 72 located in the middle of the top surface of the welding platform plate 71. The welding platform cover plate 72 is U-shaped, and a through groove for the copper strip to pass through is formed between the welding platform cover plate 72 and the welding platform plate 71. In order to ensure accuracy, the welding platform cover plate 72 at the inlet of the through groove is set with a certain curvature to facilitate the copper strip to enter the through groove. The top surface of the welding platform cover plate 72 is provided with a through hole corresponding to the vertical direction of the welding component 4. The welding component 4 can detect whether the copper strips of the two copper strip rolls 2 are connected through the through hole, and determine whether to drive the laser welder for welding. The top surface of the welding platform plate 71 is located directly below the through hole and is embedded with a welding platform support plate 73. The material of the welding platform support plate 73 is selected according to the welding needs. When the laser welder is shot at the welding platform support plate 73 during welding, it can be guaranteed not to be damaged, thereby improving the strength of the entire welding table 7 during welding. The top surface of the platform plate 71 is located on both sides of the welding table support plate 73 and is provided with negative pressure suction holes 74 for adsorbing the copper strip, so that the roll head entry hole at the welding position can be observed. The negative pressure adsorption is to facilitate the copper strip to be adsorbed and better placed on the welding platform when it is sent over, so as to facilitate subsequent stacking and accurately send the copper strip into the through groove to complete welding. The welding clamping member 8 includes a first clamping member 81 and a second clamping member 82 from left to right. The first clamping member 81 and the second clamping member 82 are respectively located on both sides of the welding table cover plate 72. The first clamping member 81 is used to clamp the copper strip of the copper strip roll waiting for feeding on the welding table 7 sent by the mobile docking assembly 9, and the second clamping member 82 is used to clamp the copper strip tail of the copper strip roll being fed. At the same time, a sensor for detecting whether the copper strip exists is set in the welding table cover plate 72. When it is detected that the copper strip does not exist, the second clamping member 82 presses the tail end of the copper strip downward so that the tail end of the copper strip is just located at the welding position.

[0052] Reference Figure 5-Figure 10 The mobile docking assembly 9 includes two upper and lower X-axis conveying guide rails 91, an X-axis slider connecting plate 92 installed between the two X-axis conveying guide rails 91, a Y-axis conveying guide rail 93 installed on the X-axis slider connecting plate 92, a Y-axis slider connecting plate 94 installed on the Y-axis conveying guide rail 93 and a chuck 95 fixed on the Y-axis slider connecting plate 94. The chuck 95 can adjust its position up and down to clamp the copper strip head of the second copper strip roll 22. The X-axis conveying guide rails 91 and the Y-axis conveying guide rails 93 are used to adjust the movement of the chuck 95 in the up, down, left and right directions, so that when the chuck 95 clamps the copper strip, the chuck 95 moves up and down following the initial position of the copper strip. When the chuck 95 is conveyed to the welding table 7, the chuck 95 moves up and down with the copper strip head to deliver the copper strip into the welding table cover 72.

[0053] Reference Figure 2-Figure 3 as well as Figure 11-Figure 14The first guide roller 111, the second guide roller 112 and the discharge roller 12 are of the same size and structure. The first guide roller 111, the second guide roller 112 and the discharge roller 12 all include a bare rod and an adjustment rod adapted to the width of the copper belt. The same end of the multiple adjustment rods passes through the machine base 1 and is connected to a synchronous belt 15 to achieve synchronous rotation of the multiple adjustment rods. A tensioning drive 16 for adjusting and driving the synchronous belt 15 to rotate is installed on the side of the machine base 1, and the tensioning drive 16 can move up and down.

[0054] The adjusting rod comprises a guide fixed roller 1111, a transmission shaft 1112 coaxially arranged with the guide fixed roller 1111, a sprocket 1113 installed at the end of the transmission shaft 1112, a threaded rod 1117 coaxially fixed with the transmission shaft 1112 and located inside the guide fixed roller 1111, a rotating tube 1116 rotatably installed on the outer side of the end of the guide fixed roller 1111, and two movable stops 1115. The transmission shaft 1112 and the threaded rod 1117 are both rotatably connected with the guide fixed roller 1111. The threaded rod 1117 is a double-headed screw with opposite threads at both ends. The two movable stops 1115 are symmetrically arranged at both ends of the double-headed screw. One end of the two movable stops 1115 is adapted to the thread of the double-headed screw, and the other end is slidably arranged on the outer side of the rotating tube 1116. The movable stop 1115 is composed of concentric rings and stop rings. The inner ring of the core ring is threadedly connected to the double-headed screw, and the outer ring of the concentric ring is slidably sleeved on the guide fixed roller 1111. The inner ring and the outer ring are fixed by a protrusion, and the surface of the guide fixed roller 1111 is symmetrically provided with grooves for the protrusions to pass through on both sides of the rotating tube 1116 to ensure the stability of the horizontal sliding of the concentric ring. At the same time, the outer ring of the concentric ring and the baffle ring are fixed by a connecting rod to push the baffle ring to slide on the rotating tube 1116. The baffle ring can block the copper belt and limit the copper belt to slide between the two baffle rings for transportation to avoid deviation during transportation. The distance between the two baffle rings is adjusted by rotating the threaded rod 1117 to adapt to copper belts of different widths and ensure that the copper belt is always in the middle of the rotating tube 1116. The rotating tube 1116 can rotate on the guide fixed roller 1111 to better transport the copper belt forward during transportation.

[0055] At the same time, in order to reposition the copper belt roll 2 on the machine base 1 and place the copper belt, the adjusting rod also includes a connecting block sleeved on the outside of the transmission shaft 1112 and a lifting cylinder 1114 for driving the connecting block to rise and fall. The extension and retraction of the lifting cylinder 1114 can drive the transmission shaft 1112 and the guide fixed roller 1111 to rise and fall, so as to facilitate the placement of the copper belt on the guide roller 11. When the lifting cylinder 1114 is lifted and lowered, in order to ensure that the synchronous belt 15 can still drive the three transmission sprockets 1113 to rotate, the tensioning drive component is also lifted and lowered to ensure that the synchronous belt 15 is always tensioned. At the same time, the motor on the tensioning drive component can also drive multiple transmission shafts 1112 to rotate under the action of the synchronous belt 15. The first guide roller 10 and the second guide roller 14 each include a light rod at the lower end and a moving rod at the upper end, wherein the moving rod is composed of a guide roller 101 and a support shaft 102 which are coaxially connected, a sleeve block is sleeved on the outer side of the support shaft 102, and a support cylinder 103 for driving the guide roller 101 to rise and fall is connected to the sleeve block, the support cylinder 103 and the lifting cylinder 1114 are both fixed in the machine base 1, and the lifting of the support cylinder 103 can drive the guide roller 101 and the support shaft 102 to rise and fall, thereby adjusting the gap between the first guide roller 10 and the second guide roller 14 placed in the copper strip.

[0056] Working principle: When in use, the copper strip on the first copper strip roll 21 first passes through the first guide roller 10, the first guide roller 111, the waiting alternating component 6, the welding table 7, the discharging roller frame, the lifting and caching component 13 and the second guide roller 14, so as to realize the conveying and loading of the copper strip on the first copper strip roll 21, and when passing through the lifting and caching component 13, the lifting and caching component 13 drives the copper strip at this position to move downward, and a part of the copper strip material is pre-stored;

[0057] When it is detected that the first copper tape roll 21 is about to be used up, the copper tape tail of the first copper tape roll 21 passes through the second clamping piece 82 on the welding table 7, and the copper tape at the tail end of the first copper tape roll 21 is clamped and fixed by the second clamping piece 82. At the same time, the pressure rod 136 of the lifting cache assembly 13 moves upward to start releasing the pre-stored copper tape material to enable continuous feeding, and the mobile docking assembly 9 is started at the same time. First, under the adjustment of the Y-axis conveying guide rail 93, the clamping head 95 is horizontally aligned with the copper tape head of the second copper tape roll 22 located at the waiting alternating assembly 6. Then, under the adjustment of the X-axis conveying guide rail 91, the clamping head 95 first moves toward the copper tape head of the second copper tape roll 22 and clamps the copper tape head. After clamping, it starts to move toward the welding mechanism. At this time, during the movement, the Y-axis conveying guide rail 93 is adjusted again to make the clamped copper tape head Located on the top surface of the welding platform plate 71, the clamped copper strip head is finally transported into the welding platform cover plate 72 until the copper strip head at the end of the second copper strip roll 22 is in contact and aligned with the copper strip tail of the first copper strip roll 21, and then the first clamping member 81 presses the copper strip of the second copper strip roll 22 downward, moves the docking assembly 9 to start resetting, and starts the laser welder of the welding assembly 4 to weld the heads and tails of the two copper strips. After welding is completed, the first clamping member 81 and the second clamping member 82 are released upward at the same time. At this time, the copper strip of the second copper strip roll 22 begins to be transported and fed, and it also changes into a new feeding copper strip roll. After the start, the pressure rod 136 of the lifting cache assembly 13 drives the copper strip to move downward again, and continues to pre-store a part of the copper strip material for the next connection; and the used copper strip roll can be replaced manually.

[0058] Before loading, under the initial placement of the copper strip, the copper strip of the first copper strip roll 21 passes through the first guide roller 111 and the discharging roller 12, and the copper strip of the second copper strip roll 22 passes through the second guide roller 112 and rests on the waiting alternating component 6. At this time, the motor of the tensioning drive 16 is started, and the motor drives the synchronous belt 15 to work, and drives the three transmission shafts 1112 to rotate under the action of the sprocket 1113, and finally drives the threaded rod 1117 to rotate. When the threaded rod 1117 rotates, the two moving stops 1115 on each threaded rod 1117 begin to move close to and away from each other at the same time, until the two moving stops 1115 are close to and in contact with the two ends of the copper strip respectively, so that the copper strip is transported forward between the two moving stops 1115 to ensure stability during transportation and docking.

[0059] When a new copper strip coil is placed on the machine base 1:

[0060] If it is installed at the first copper strip roll 21, the supporting cylinder 103 of the first guide roller 111 and the lifting cylinder 1114 of the first guide roller 10 are started to shrink at the same time, so that the gap between the first guide roller 10 and the first guide roller 111 for the copper strip to pass through becomes larger, so that the copper strip can be put in easily. After the copper strip is put in, it returns to the initial position and starts to place the copper strip on the top surface of the U-shaped support plate 61. At this time, the blocking cylinder 511 of the first detection member 51 extends, and the copper strip is blocked by the L-shaped baffle 512. When the detection sensor 513 detects the copper strip, the first pressing member 62 moves downward to press the copper strip until the copper strip is clamped by the clamp 95.

[0061] If it is installed at the second copper strip roll 22, start the supporting cylinder 103 of the second guide roller 112, enlarge the gap on the second guide roller 112 for the copper strip to pass through, put the copper strip in and restore the initial position, and start to move the copper strip to the bottom surface of the U-shaped support plate 61. At this time, the blocking cylinder 511 of the second detection member 52 extends, and the copper strip is blocked by the L-shaped baffle 512. When the detection sensor 513 detects the copper strip, the second pressing member 63 moves upward to press the copper strip until the copper strip is clamped by the chuck 95.
