Description

Technical Field

[0001] The invention relates to the technical field of copper foil adhesive backing machines, in particular to a multi-stage fully automatic copper foil adhesive backing machine. Background Art

[0002] Copper foil is mainly used as a shielding layer in transformers to reduce electromagnetic interference and static electricity. Copper foil adhesive is a conductive tape pasted on copper foil to eliminate electromagnetic interference (EMI), isolate electromagnetic waves from harming the human body, and avoid unnecessary voltage or current affecting the function. The copper foil adhesive machine is a device specially used for processing copper foil of electronic transformers. It can complete a series of processes such as adhesive backing, cutting, and sticking peripheral tape on copper foil.

[0003] At present, there are many single-stage copper foil adhesive machines on the market, and most of the equipment is semi-automatic. Most of the loading, material handling, material turning, and material transfer need to be done manually.

[0061] The preferred specific embodiments for implementing the present invention are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0062] See also Figure 1 and Figure 2The present invention provides a multi-stage fully automatic copper foil adhesive machine, which is composed of a chassis 11 and a tape supply unit 1 installed inside the chassis 11, a copper foil feeding unit 2, a tape A pasting unit 3, a tape A cutting and folding unit 4, a tape B folding unit 5, a flip unit 6, a conveying unit 7, a tape C folding unit 8 and a copper foil unloading unit 9. Unlike the existing copper foil adhesive machine which can only paste one high-temperature tape on the copper foil, the present invention can paste the high-temperature tape A, the high-temperature tape B and the high-temperature tape C on the copper foil in turn during one processing. The processing process is as follows: Fig.19 As shown, multi-section automatic back gluing is achieved.

[0063] The tape supply unit 1 of the present invention is used to provide a long strip of high temperature tape A for the copper foil, specifically as follows Figure 3 As shown, the tape supply unit 1 includes a tape reel a101 wound with a high-temperature tape A, and a roller a103 capable of moving up and down and a plurality of rotatable guide wheels a102 are provided on one side of the tape reel a101. After the high-temperature tape A is pulled out from the tape reel a101, it passes through the plurality of guide wheels a102 and the roller a103 in sequence, thereby realizing the supply of the high-temperature tape A;

[0064] At the same time, the copper foil needs to be loaded. Figure 4-6 As shown, the copper foil feeding unit 2 provided by the present invention includes a clip 201, both sides of the clip 201 are limited by a clip positioning cylinder 205, a plurality of lifting plates 202 that can move up and down are installed on the clip 201, two limiting columns 203 are arranged at both ends of each lifting plate 202, the bottom ends of the limiting columns 203 are fixed to the top of the clip 201, and a lifting seat 204 for pushing the lifting plate 202 to move up and down is arranged at the bottom of the clip 201. The copper foil to be processed is located at the top of each lifting plate 202 and is limited by the limiting columns 203 at both ends. During the feeding process, the lifting seat driving mechanism 206 drives the lifting seat 204 to move to the bottom of each lifting plate 202, and then the lifting seat 204 pushes the lifting plate 202 to drive the copper foil located above it to move upward, so as to realize the supply of the copper foil to be processed.

[0065] Further, the lifted copper foil is moved to the high temperature tape A by the tape A pasting unit 3, as shown in the following example: Figure 7 and 8 As shown, the tape A pasting unit 3 includes a copper foil unloading platform 301 located on one side of the tape supply unit 1. A traction clamp a302 for clamping the high-temperature tape A is provided on the side of the copper foil unloading platform 301 away from the tape supply unit 1. The traction clamp a302 is driven by the rear clamp a driving mechanism 306 to move left and right. The traction clamp a302 is used to clamp one end of the high-temperature tape A, and then the clamp a driving mechanism 306 drives the traction clamp a302 to pull the high-temperature tape A to the right, so that the high-temperature tape A can be as shown in FIG. Figure 7 and 8As shown, it is located above the copper foil discharge platform 301;

[0066] Then, the suction cup a driving mechanism 305 located on the top of the copper foil discharge platform 301 is used to drive the vacuum suction cup a304 below it to move forward and then downward to absorb the copper foil to be processed on the lifting tray 202, and then move up and backward in sequence to move the copper foil to the top of the copper foil discharge platform 301, and then the suction cup a driving mechanism 305 continues to drive the vacuum suction cup a304 to move downward to place the copper foil on the high-temperature tape A.

[0067] After each copper foil is loaded, the traction clamp a302 will pull the high temperature tape A to drive the copper foil to move to the right. Figure 8 At this time, the tape cutter a303 located at the rear side of the copper foil unloading platform 301 cuts off the high-temperature tape A. The high-temperature tape A is as shown in FIG. Fig.19 As shown, it is pasted on the bottom of the copper foil.

[0068] Next, the high temperature tape A needs to be attached to the copper foil. The tape A cutting and folding unit 4 of the present invention first cuts off the excess high temperature tape A at both ends of each copper foil and then folds the remaining high temperature tape A upward by 180 degrees to attach it to the copper foil. Fig.19 As shown, specifically Figure 8-11 As shown, the tape A cutting and folding unit 4 includes a folding machine base a402 located on one side of the copper foil discharge platform 301, and a trimming knife 401 for cutting off excess high-temperature tape A at both ends of the copper foil is provided on the top of the folding machine base a402, and two symmetrically distributed long folding push plates 403 are installed above the folding machine base a402, and the two long folding push plates 403 are driven by a folding cylinder 405 located at the bottom thereof to move forward and backward. When working, the trimming knife 401 is first driven downward by the up and down driving mechanism 404 to cut off excess high-temperature tape A at both ends of the copper foil, and then the two long folding push plates 403 are driven to move toward the middle by the folding cylinder 405, and the long folding push plates 403 push the high-temperature tape A on both sides of the copper foil to fold upward 180°, so that the high-temperature tape A is pasted on the top of the copper foil, thereby completing the pasting of the first section of high-temperature tape.

[0069] To facilitate the pasting of the second section of high-temperature tape, the tape A cutting and folding unit 4 of the present invention also includes a tripod 407 located on the front side of the folding machine base a402, and three groups of vacuum suction cups b406 are installed on the rear side of the tripod 407. The suction cup driving mechanism 408 installed inside the installation box 409 drives the tripod 407 to drive the vacuum suction cups b406 to move left, so that the group of vacuum suction cups b406 located on the far left can absorb the copper foil with high-temperature tape A bonded on the top of the copper foil discharge platform 301, and then drive the vacuum suction cups b406 to move to the top of the folding machine base a402 to place the copper foil with high-temperature tape A bonded in the tape B folding unit 5 for pasting of high-temperature tape B.

[0070] Specific as Fig.12 As shown, the tape B folding unit 5 includes a folding base b501 located on one side of the folding base a402. The middle group of vacuum suction cups b406 among the three moving groups of vacuum suction cups b406 absorbs the copper foil on the top of the folding base a402 and moves it to the top of the folding base b501. Prior to this, one end of the high-temperature tape B wound in the tape reel b507 on the rear side of the folding base b501 passes through the rotating roller b509 and the guide wheel b508 in turn, and then is pulled by the traction clamp located on one side of the guide wheel b508. b505 is clamped, and the traction clamp b505 is driven by the clamp driving mechanism 5010 below to pull the high-temperature tape B to move to the left. The specification of the high-temperature tape B required at this stage is 8×15mm, that is, the length of the high-temperature tape B pulled by the traction clamp b505 is consistent with the above specifications, so the tape cutter b506 can cut it. The specific control means can be realized by the PLC control program. This technology belongs to the mature technical solution in the prior art, so it will not be further described in this application;

[0071] Then, the glue sticking head driving mechanism 504 on the top of the folding machine base b501 drives the glue sticking head a503 to move the cut high-temperature adhesive tape B to the top of the folding machine base b501. Then, a group of vacuum suction cups b406 located in the middle absorb the copper foil on the top of the folding machine base a402 and move it above the high-temperature adhesive tape B. At this time, the high-temperature adhesive tape B is attached to the middle of the copper foil. Fig.19 As shown;

[0072] Finally, two front-to-back folding short push plates 502 located on one side of the top of the folding machine base b501 push the high-temperature tape B toward the middle, so that the high-temperature tape B is folded down 180° and can be attached to the copper foil, thus completing the pasting of the second section of the high-temperature tape.

[0073] It is worth mentioning that the folding machine base a402 and the folding machine base b501 of the present invention are both connected with a support platform that can move up and down. When the copper foil moves to the folding machine base a402 and the folding machine base b501, it contacts the support platform. There is also a lifting cylinder at the bottom of the support platform that can push it to move up and down. When the high-temperature tape A and the high-temperature tape B are folded 180°, the copper foil is driven by the support platform to move between the two long folding push plates 403 and the two short folding push plates 502, so that the two long folding push plates 403 and the two short folding push plates 502 can first fold the high-temperature tape A and the high-temperature tape B upward by 90°, and then the support platform drives the copper foil to move to the bottom of the two long folding push plates 403 and the two short folding push plates 502. At this time, the two long folding push plates 403 and the two short folding push plates 502 continue to move toward the middle, so that the high-temperature tape A and the high-temperature tape B can continue to be folded 90° to be pasted on the copper foil. That is to say, in the present invention, the two folded long push plates 403 push the high-temperature adhesive tape A to fold upward 180°, and the two folded short push plates 502 push the high-temperature adhesive tape B to fold upward 180°, which are implemented in two stages.

[0074] Then the third section of high-temperature tape is pasted. The flip unit 6 in the present invention drives the copper foil pasted with high-temperature tape A and high-temperature tape B to rotate 90° horizontally and 180° vertically in sequence, and then moves the copper foil to the conveying unit 7. The conveying unit 7 conveys the high-temperature tape C toward the tape C folding unit 8. The tape C folding unit 8 first pastes the high-temperature tape C on the top of the lower section of the copper foil and then folds it downward to stick the high-temperature tape C on the copper foil.

[0075] Specific as Fig.15 As shown, the flip unit 6 includes two suction plates 601 distributed up and down, the suction plates 601 are used to clamp the copper foil pasted with the high-temperature tape A and the high-temperature tape B, two groups of angle rotating cylinders 603 are arranged between the two suction plates 601, and upper and lower material receiving cylinders 602 for driving the suction plates 601 to move up and down are arranged between the suction plates 601 and the angle rotating cylinders 603. Among the three groups of moving angle rotating cylinders 603, the group of angle rotating cylinders 603 located on the far right can absorb the copper foil on the top of the folding machine base b501 and move it to the top of the suction plate 601 located above, and then the angle rotating cylinder 603 and the up and down flipping cylinder 604 drive the suction plate 601 to drive the copper foil to rotate 90° in the horizontal plane and 180° in the vertical plane, so that the long sides of the upper and lower suction plates 601 are perpendicular to each other;

[0076] Furthermore, the conveying unit 7 includes a conveying tank belt 701, which is located below the suction plate 601. A plurality of copper foil jigs 702 are provided on the top of the conveying tank belt 701 to rotate with the conveying tank belt 701. Fig.16 and 17As shown, the tape C folding unit 8 includes a tape reel c801 located at the rear side of the conveyor tank belt 701, and a high-temperature tape C is wound on the tape reel c801. A plurality of rotatable rollers c804 are provided below the tape reel c801, and a traction clamp c802 for pulling the high-temperature tape C is provided on one side of the lowest roller c804, and a tape cutter c803 for cutting the high-temperature tape C is provided on the rear side of the traction clamp c802, and a gluing head b805 for gluing the cut high-temperature tape C to the lower section of the copper foil on the copper foil fixture 702 is provided on the top of the conveyor tank belt 701, wherein the driving structures of the traction clamp c802 and the gluing head b805 are respectively the same as the driving structures of the traction clamp b505 and the gluing head a503, and are not further described here;

[0077] In the present invention, the long side of the copper foil fixture 702 is in the same direction as the long side of the suction plate 601 located below, so that the suction plate 601 can move downward under the drive of the upper and lower material receiving cylinders 602 to move the copper foil pasted with the high temperature tape A and the high temperature tape B to the copper foil fixture 702 located at the position of the loading station 703. The copper foil fixture 702 will drive the copper foil to move to the right under the conveyance of the conveyor tank belt 701;

[0078] Before the copper foil moves to the position of the pushing cylinder 806, one end of the high-temperature tape C wrapped around the outer end of the tape reel c801 is clamped by the traction clamp c802 and the high-temperature tape C is pulled to the left by the traction clamp c802. The pulled high-temperature tape C is passed through multiple rollers c804 in turn. The specification of the high-temperature tape C required in this stage is 8×12.5mm, that is, when the length of the high-temperature tape C pulled out by the traction clamp c802 is 12.5mm, the tape cutter c803 located on the rear side of the traction clamp c802 can be controlled to cut it (the specific control means used can be implemented through the PLC control program, which is a mature technical solution in the prior art, so it will not be further described in this application), and then the cut high-temperature tape C is pasted to the lower section of the copper foil by the glue head b805 located on the top of the conveyor tank belt 701. The position of the high-temperature tape C on the copper foil is as shown in Fig.19 As shown;

[0079] Next, the copper foil with the high-temperature tape C attached will follow the copper foil fixture 702 and pass through the pushing cylinder 806, the folding cylinder 807 and the clamping cylinder 808 in sequence. During the movement, the pushing cylinder 806 will first push the high-temperature tape attached to the lower section of the copper foil to bend downward 90°, and then the folding cylinder 807 will push the bent high-temperature tape C to be attached to the copper foil. Finally, the clamping cylinder 808 will clamp the copper foil and the high-temperature tape C to make them tightly bonded.

[0080] It is worth noting that if Fig.17As shown, the end face of the moving end of the pushing cylinder 806 of the present invention is flat so as to push the high-temperature tape C to bend it 90°, and the moving end of the folding cylinder 807 is a flat plate, and the top of the moving end is located under the copper foil and can push the bent high-temperature tape C to adhere to the copper foil.

[0081] Finally, if Fig.18 As shown, the copper foil unloading unit 9 is used to move the finished copper foil with high temperature tape A, high temperature tape B and high temperature tape C to the material box 10 to realize automatic unloading. The specific structure of the copper foil unloading unit 9 includes a vacuum suction cup c901 located above the right end of the conveyor tank belt 701, and a material box 10 for holding the copper foil is provided below the right side of the vacuum suction cup c901. The vacuum suction cup c901 is driven by the suction cup c driving mechanism 902 at the top. When in use, the suction cup c driving mechanism 902 drives the vacuum suction cup c901 to absorb the copper foil on the copper foil fixture 702 located at the unloading station 704, and then automatically moves it to the inside of the material box 10, without manual participation, thereby improving the efficiency of copper foil back glue processing.

[0082] In the present invention, the loading of copper foil, the loading of high-temperature tape A, the loading of high-temperature tape B and the loading of high-temperature tape C can all be completed automatically. Compared with the prior art which adopts manual loading, material handling, material turning and material transfer, the present invention can avoid manual errors and improve the production capacity and accuracy of copper foil backing adhesive processing.

[0083] Based on the above content and the accompanying drawings, those skilled in the art can understand and implement the present invention. In addition, any non-creative modifications made to the present invention by those skilled in the art without creative work still fall within the protection scope of the present invention.
