Description

Technical Field

[0001] The invention belongs to the technical field of etching foil production, and more specifically, relates to a fully automatic foil placing mechanism for chemically etching foil. Background Art

[0002] The existing foil unwinding machine reeling device of the chemical foil and etching foil production line is basically semi-automatic or manual. When a new foil roll is put on the foil unwinding machine, it is necessary to manually change the roll, and when the foil pieces are connected, they are connected manually with aluminum buckles. When the foil unwinding machine of the production line needs to replace the foil after putting a roll of foil, it can only be changed manually, one is low efficiency, and the other is that a roll of foil is too heavy, which is prone to safety hazards; the transportation of the foil roll and the unloading of the drive roller of the foil roll need to be handled manually, which is too inefficient; when multiple production lines in a workshop need to change rolls at the same time, the rolls may not be changed in time, which seriously affects the normal production of the production line.

[0031] In the present invention, the foil winding roller 103 is installed on the foil unwinding machine 101, and the foil unwinding motor 102 is connected to the foil unwinding roller 104 to drive the foil unwinding roller 104 to rotate, so that the foil 112 is loosened from the foil unwinding roller 104 and transferred to the next process. When the foil 112 on the foil unwinding roller 104 is completely unwound, the foil unwinding installation mechanism is started, and the foil unwinding installation mechanism removes the foil unwinding roller 104 that has unwound the foil 112 from the foil unwinding machine 101 and transports it to the foil unwinding conveying platform 4. The foil unwinding conveying platform 4 conveys the foil unwinding roller 104 to the foil roller placing vehicle 6. At this time, the automatic transport vehicle 5 carries the foil winding roller 103 and transfers the foil winding roller 103 to the foil unwinding conveying platform 4.

When the automatic transport vehicle 5 transports the foil roll 104 to one side of the foil roll conveying platform 4, the third position alignment switch 504 and the first position alignment switch 404 are used to realize the positioning action of the automatic transport vehicle 5, so as to ensure that the automatic transport vehicle 5 can accurately park on one side of the foil roll conveying platform 4. After completing the position alignment action, the second conveying motor is started to transfer the foil roll 104 together with the foil roll base 506 to the first conveyor belt 402 of the foil roll conveying platform 4. Through the action of the second limit switch 505 and the third limit switch, the foil roll base 506 is limited to move to the position on the foil roll conveying platform 4, so as to ensure that the foil roll 104 is just transferred to the foil roll machine platform 101 for installing the foil roll 104 directly below, so as to ensure that the up and down moving guide rail 105 can be connected with the foil roll 104

[0036] In one embodiment, a third limit switch corresponding to the second limit switch 505 is provided on the first conveyor belt 402.

During the rolling process, the sixth cylinder 110 starts to drive the extrusion rotating roller 111 to contact the foil release roller 104, just pressing the foil 112, to ensure that the foil 112 can be tightly rolled on the foil release roller 104 when the foil 112 is rolled.

[0041] Working principle:

[0042] 1. The foil placing machine 101 is in normal operation. Figures 1 to 3 As shown;

[0043] 1.1 Under normal operation of the production line, the transmission process of the foil 112 on the foil unloading side is that the foil 112 is unloaded from the foil unloading machine 101, passes through the foil receiving mechanism 2, and then is transferred to the buffer mechanism 3, and then is transferred to the next process, i.e., the electrochemical tank;

[0044] 1.2 Foil unwinding machine 101: The foil unwinding motor 102 rotates, driving the foil unwinding roller 104 to rotate, and the foil 112 is unwinded from the foil unwinding roller 104. At this time, the fifth cylinder 108 moves, driving the eighth transmission roller 109 to press the foil 112 downward, so that the foil 112 can pass between the foil receiving platform pressing mechanism 201 and the foil receiving platform fixed pressing mechanism 202; the foil 112 after passing through enters the buffer mechanism 3 after passing through the fourth transmission roller 306;

[0045] 1.3 Foil splicing mechanism 2: During normal operation, all mechanisms of the automatic foil splicing station are not in operation, and the foil 112 only passes through the foil splicing mechanism 2;

[0046] 1.4 Buffer mechanism 3: Under normal operation, the various mechanisms of the buffer mechanism 3 do not operate, and the buffer moving roller 302 is located at the top of the buffer moving guide rail 301 to ensure that the maximum amount of foil 112 can be cached; the foil 112 is transmitted from the fourth transmission roller 306 to the buffer mechanism 3, and passes through the buffer moving roller 302, the sixth transmission roller 308, and the seventh transmission roller 309 in turn; and finally transmitted to the electrochemical cell.

[0047] 2. The operation process of the lower roller of the foil placing machine 101, such as Figures 4 to 6 As shown;

[0048] 2.1 Operation process of the foil unwinding machine 101 after unwinding: When the foil 112 on the foil unwinding roller 104 is conveyed (whether the aluminum foil roll has been unwound is calculated by counting meters and rotating speed), the fourth cylinder 304 is actuated to drive the second squeezing roller 305 to move upward, and the foil 112 is pressed tightly between the second squeezing roller 305 and the fourth transmission roller 306. The foil 112 cannot be transferred from the foil unwinding side to the buffer mechanism 3, and can only be transferred from the buffer mechanism 3 to the next process; at the same time, the second cylinder 204 is actuated to drive the first squeezing roller 206 to move downward, and the foil 112 is pressed tightly between the first squeezing roller 206 and the fixed squeezing roller 208. The foil placing motor 102 stops running at this time; then the third cylinder 205 is started to drive the cutter 207 to move downward to cut the foil 112; the fifth cylinder 108 stops running and retracts the eighth transmission roller 109; when the foil 112 is cut off, the sixth cylinder 110 is started to drive the extrusion rotating roller 111 to move toward the foil placing roller 104 to press the foil 112 on the foil placing roller 104, and the foil placing motor 102 is reversed at this time to roll the remaining foil 112 on the foil placing roller 104, and the foil 112 is loosened during the rolling process by squeezing the rotating roller 111, and after the rolling is completed, the foil placing motor 102 stops moving;

[0049] 2.2 The process of rolling down the foil roller 104: After the foil motor 102 stops, the sixth cylinder 110 also stops, and the squeezing rotating roller 111 is retracted; at the same time, the second cylinder 204 and the third cylinder 205 stop, and the first squeezing roller 206 and the cutter 207 are retracted; then, the up-down moving motor 106 operates, driving the up-down moving guide rail 105 to move upward until it is connected with the foil roller 104; at this time, the foil roller 104 is disengaged from the foil motor 102, and the foil roller 104 moves downward through the up-down moving guide rail 105 to the first conveyor belt 402 on the foil conveying platform 4. During the downward movement of the foil roller 104, until it contacts the first limit switch 107, the up-down moving motor 106 stops, and the foil roller 104 is placed on the first conveyor belt 402;

[0050] 2.3 The foil roller 104 is transferred to the foil roller placement vehicle 6: When the foil roller 104 is placed on the first conveyor belt 402, the first conveying motor starts to drive the first transmission roller 403 to rotate, thereby driving the first conveyor belt 402 to operate. The foil roller 104 is transferred toward the foil roller placement vehicle 6 under the action of the first conveyor belt 402. After reaching the foil roll moving guide rail 605 (the moving position of the foil roller 104 is calculated by time), the first conveying motor stops, and the foil roll moving motor 606 starts to start. The foil roller 104 moves to the third conveyor belt 602 under the action of the foil roll moving guide rail 605. At the same time, the third conveying motor starts to drive the third transmission roller 603 to rotate, driving the third conveyor belt 602 to operate, and transferring the foil roller 104 to the specified position on the placement vehicle body 601, that is, after contacting one of the third limit switches 407, the foil roll moving motor 606 and the third conveying motor stop to complete the conveying action of the foil roller 104.

[0051] 3. The automatic transport vehicle 5 and the foil unwinding machine 101 are in operation. Figures 7 to 9 As shown;

[0052] 3.1 Alignment process: After receiving the roll-up instruction, the automatic transport vehicle 5 carries the foil roll 103 and arrives at the foil unwinding machine 101, and locates the parking position through the third position alignment switch 504 and the first position alignment switch 404;

[0053] 3.2 Rolling process: After the alignment is completed, the second conveying motor starts, drives the second transmission roller 503 to operate, drives the second conveyor belt 502 to rotate, and transmits the foil roll base 506 placed on the second conveyor belt 502 and the foil roll roller 103 on the foil roll base 506 to the foil unwinding conveying platform 4. At the same time, the first conveying motor starts, drives the first transmission roller 403 to operate, and after the foil roll base 506 is transmitted to the first conveyor belt 402, it continues to move under the action of the first conveyor belt 402 until the second limit switch 505 on the foil roll base 506 contacts the third limit switch 407 on the foil unwinding conveying platform 4, and the first conveying motor stops; then, the up and down moving motor 106 starts, drives the up and down moving guide rail 105 to move upward, and after connecting with the foil roll roller 103, the foil roll roller 103 is transported upward to the foil unwinding machine 101, installed and fixed, and after installation, the foil unwinding motor 102 is buckled with the foil unwinding machine with aluminum foil rolled;

[0054] 3.3 Lowering base process: the second conveying motor of the automatic transport vehicle 5 and the first conveying motor of the foil unloading conveying platform 4 are reversed at the same time (opposite to the running direction of the rolling process); the base slowly runs from the first conveyor belt 402 to the second conveyor belt 502, and when the base leaves the foil unloading conveying platform 4, the first conveying motor stops running; when the foil roll base 506 runs on the second conveyor belt 502, until the second limit switch 505 on the foil roll base 506 contacts the fifth limit switch on the automatic transport vehicle 5, the second conveying motor stops moving, the lowering base ends, and the rectification and rolling process is completed.

[0055] 4. The operation process of the buffer mechanism 3, such as Figure 3 and Fig.12 As shown;

[0056] 4.1 When the foil placing machine 101 operates normally, the fourth cylinder 304 does not operate, and the foil 112 passes between the second squeezing roller 305 and the fourth transmission roller 306, and then passes through the fifth transmission roller 307, the buffer moving roller 302, the sixth transmission roller 308 and the seventh transmission roller 309 in sequence, and then enters the next process; at this time, the buffer moving roller 302 is located at the top of the buffer moving guide rail 301, that is, Figure 2 The leftmost position ensures that the amount of foil 112 cached on the buffer mechanism 3 is the largest at this time;

[0057] 4.2 When the foil placing machine 101 changes rolls: the fourth cylinder 304 operates to drive the second squeezing roller 305 to move upward, pressing the foil 112 between the second squeezing roller 305 and the fourth transmission roller 306, so that the foil 112 cannot be transferred to the buffer mechanism 3. At the same time, the buffer moving motor 303 operates in the reverse direction to drive the buffer moving roller 302 to move rightward, and the foil 112 is transferred to the next process through the buffer mechanism 3. The operating speed of the buffer moving motor 303 must ensure that the speed of the foil 112 is consistent with that of the production line.

[0058] 4.3 After the foil unwinding machine 101 completes the roll change: the fourth cylinder 304 stops operating, the second squeezing roller 305 returns to its original position, the buffer moving motor 303 runs forward at full speed, and after the buffer moving roller 302 moves to the leftmost end of the buffer moving guide rail 301, the buffer moving motor 303 stops running and returns to the normal operating mode.

[0059] 5. The working process of the foil joining mechanism 2 is as follows: Figures 11 to 13 As shown;

[0060] 5.1 Moving process of the suction cup 209: After the foil winding roller 103 completes the winding action, the foil splicing moving motor 211 is started to drive the foil splicing moving guide rail 210 to extend toward the foil unwinding machine 101 until the suction cup 209 contacts the foil 112 on the foil unwinding roller 104 on the foil unwinding machine 101, and the suction cup 209 sucks the foil 112;

[0061] 5.2 The process of the suction cup 209 sucking the foil 112 and moving it: After the suction cup 209 sucks the foil 112, the foil-joining moving motor 211 rotates in the reverse direction, and the foil-joining moving guide rail 210 retracts. When passing through the eighth transmission roller 109, the fifth cylinder 108 is started to slowly drive the eighth transmission roller 109 to move downward, pressing the foil 112, and ensuring that the foil 112 passes between the foil-joining platform pressing mechanism 201 and the foil-joining platform fixed pressing mechanism 202; after the suction cup 209 pulls the foil 112 and passes between the foil-joining platform pressing mechanism 201 and the foil-joining platform fixed pressing mechanism 202, it moves to one side of the foil-joining platform pressing mechanism 201 and the foil-joining platform fixed pressing mechanism 202, until the foil-joining moving guide rail 210 is completely retracted, the foil-joining moving motor 211 stops operating, the suction cup 209 releases the foil 112, and the foil 112 falls onto the foil-joining platform fixed pressing mechanism 202;

[0062] 5.3 Foil 112 docking process: At this time, the two disconnected foils 112 overlap and fall on the fixed crimping mechanism 202 of the foil connecting platform. The first cylinder 203 is started to drive the foil connecting platform pressing mechanism 201 to move downward until it is tightly engaged with the fixed crimping mechanism 202 of the foil connecting platform. The two disconnected foils 112 are tightly pressed together through the tooth-like structure on the surface of the foil connecting platform pressing mechanism 201 and the fixed crimping mechanism 202 of the foil connecting platform. After a certain period of time, the first cylinder 203 stops moving and retracts the foil connecting platform pressing mechanism 201. At this time, the crimping of the foil 112 is completed; then the fourth cylinder 304 stops running, retracts the second squeezing roller 305, and the foil 112 is normally transferred to the buffer mechanism 3.
