The transformer feeding unit 40 will be described in detail below with reference to fig. 1, 7, and 8.
As described above, the transformer feeding section 40 includes the transformer rotating section 41 for loading and positioning the transformer Tr. In one embodiment of the transformer rotating part 41, the transformer rotating part 41 includes a motor 411, a transformer positioning block 412 for positioning the transformer Tr is keyed on an output shaft of the motor, a magnet is embedded on the transformer positioning block 412 to absorb the transformer Tr, and a rotary clamping cylinder (not shown) may be further provided on the transformer rotating part 41 to clamp and position the transformer Tr together with the rotary clamping cylinder and the transformer positioning block 412. Of course, for a transformer Tr with a part of which there is no reliable adsorption structure, the transformer positioning block 412 may be replaced with a pneumatic clamping jaw, and the pneumatic clamping jaw may be used to clamp the transformer Tr. The motor can select a stepping motor, a servo motor, a speed regulating motor and the like, and preferably, the motor selects the servo motor to accurately memorize the rotating angle of the motor, so that the transformer Tr can be accurately rotated, and insufficient rotation or over-rotation is prevented.
In addition, in order to facilitate loading of the transformer Tr, the transformer delivering part 40 may further include a fifth driving part 42 for driving the transformer rotating part 41 to be transferred from the loading position 401 of the transformer Tr to the working area 402 of the copper foil Co for wrapping the transformer Tr, and the loading of the transformer Tr may be selected to be manually fed or automatically fed, and the fifth driving part 42 may be provided to avoid the problems of difficult debugging, maintenance, and maintenance caused by the fixed installation of a plurality of components at a certain position therein. The fifth driving part 42 may be an actuator known to those skilled in the art, such as a cylinder or a motor-driven slide module.
After the transformer feeding unit 40 acquires the transformer Tr at the loading position 401, the fifth driving unit 42 drives the transformer rotating unit 41 to the operation area 402 where the copper foil Co wraps the transformer Tr, and at the same time, the copper foil feeding unit 20 feeds the copper foil Co to the operation area 402 where the copper foil Co wraps the transformer Tr.
In order to send the copper foil Co of the copper foil sending-out part 20 to a work area where the copper foil Co includes a transformer Tr, the copper foil sending-out part 20 further includes a third driving part 23 that can drive the copper foil clamping part 21 and the copper foil cutting part 22 to move back and forth in the sending-out direction of the copper foil Co, and a driving stroke of the third driving part 23 is set to allow the copper foil Co clamped by the copper foil clamping part 21 to cross the transformer Tr and partially protrude from the transformer Tr to be attached to the transformer Tr; the transformer rotating part 41 has a reversing mechanism (the servo motor can be reversed) so that the copper foil Co partially protruding out of the transformer Tr is attached to the transformer Tr.
Further, the third driving part 23 can drive the copper foil clamping part 21 and the copper foil cutting part 22 to switch between clamping the copper foil Co and cutting the copper foil Co, so the third driving part 23 preferably uses a motor-driven sliding table module to realize that the copper foil sending-out part 20 can start and stop at multiple points, and meanwhile, the motor can control the starting speed and the stopping speed to perform gentle action so as to prevent the copper foil Co from being torn due to the sudden extension problem possibly occurring like a cylinder.
The fifth driving part 42 transfers the transformer rotating part 41 to the lower part of the copper foil Co clamped by the copper foil clamping part 21, and a transformer lifting part 43 is further provided on the fifth driving part 42, the transformer lifting part 43 is lifted by a cylinder or a motor drive, the transformer rotating part 41 is provided on the transformer lifting part 43, and the transformer rotating part 41 is lifted by the transformer lifting part 43 to attach the transformer Tr to the copper foil Co. After the transformer Tr is attached with the copper foil Co, since the copper foil Co spans the transformer Tr and partially protrudes from the transformer Tr, the servo motor of the transformer rotating part 41 may rotate the transformer Tr in a direction opposite to a rotation direction when the copper foil Co wraps the transformer Tr, so that the copper foil Co partially protruding from the transformer Tr is completely attached to the transformer Tr. Thus, the copper foil Co and the transformer Tr can be bonded to each other as large as possible without tension of the copper foil Co, and the copper foil Co is prevented from falling off when the transformer Tr is wrapped with the copper foil Co due to an excessively small bonding area between the copper foil Co and the transformer Tr and an excessively large tension.
Referring to fig. 7 and 8, the detection unit 50 is provided at a position where the presence or absence of the copper foil Co can be detected when the copper foil Co is wrapped around the transformer Tr. The detection unit 50 is mainly configured to monitor the operation state of the copper foil Co wrapping the transformer Tr in real time, and since tension is always provided between the copper foil feeding unit 20 and the transformer Tr when the copper foil Co wrapping the transformer Tr, the feeding position thereof can be determined by the tension, that is, the copper foil Co always matches with the preset feeding direction of the copper foil Co between the copper foil feeding unit 20 and the transformer Tr. In the case where the copper foil Co is broken or the copper foil Co is separated from the transformer Tr, the copper foil Co, which loses tension, is deviated from the predetermined feeding direction, and therefore, by providing the detecting portion 50 to detect the presence or absence of the copper foil Co in the area, the operation state of the copper foil Co when the copper foil Co is wrapped around the transformer Tr can be reliably monitored, and the output information such as alarm information can be fed back to prompt the operator to treat defective products.
In one embodiment of the detecting unit 50, the detecting unit 50 includes a reflective photosensor provided at a position where the presence or absence of the copper foil Co can be detected by irradiating the surface of the copper foil Co, and of course, a non-contact sensor for detecting the presence or absence of the copper foil Co may be selected from an opposite type photosensor and a laser displacement sensor. The reflective photoelectric sensor may be provided on the copper foil feeding portion 20, may be provided on the upper portion of the copper foil Co, or may be provided on the lower portion of the copper foil Co, so long as the surface distance thereof from the copper foil Co is within the detection range of the reflective photoelectric sensor, and one of ordinary skill in the art may select the mounting position by himself as required. Of course, in other embodiments of the detection portion 50, the detection portion 50 may also use, for example, a micro switch, a contact displacement sensor, or the like. When the detecting unit 50 uses a micro switch or a contact displacement sensor, the micro switch or the contact displacement sensor may be provided on the upper surface or the lower surface of the copper foil Co, and may further apply a certain tension to the copper foil Co by using its own elasticity. So as to ensure that the copper foil Co can always be attached to the transformer Tr due to the action of tension when wrapping the transformer Tr.
The detection unit 50 may further include a sensor for detecting whether the transformer Tr is present in the transformer rotating unit 41, and a sensor for detecting the transformer Tr is preferably a noncontact sensor such as a laser displacement sensor, a reflection type photoelectric sensor, a correlation type photoelectric sensor, or the like.
Referring to fig. 7 and 8, in order to further reliably ensure that the transformer Tr can be tightly attached when the copper foil Co is wrapped around the transformer Tr, the apparatus includes a roller pressing portion 60, the roller pressing portion 60 including a roller 61 and a second cylinder 62 driving the roller 61 to abut against a side of the copper foil Co opposite to the transformer Tr, the second cylinder 62 driving the roller 61 to press and attach the copper foil Co to the transformer Tr from a side of the copper foil Co opposite to the transformer Tr when the copper foil Co is wrapped around the transformer Tr. Meanwhile, because of the roller pressing portion 60, the tension of the copper foil Co itself may be slightly reduced to prevent the copper foil Co from being torn due to the excessive tension. Preferably, the copper foil Co fed out by the copper foil feeding section 20 is set to be fed out in a horizontal direction, the transformer rotating section 41 drives the transformer Tr to rotate in a vertical direction around an output shaft of the servo motor, and the roller pressing section 60 presses and adheres the copper foil Co to the transformer Tr from an upper portion of the copper foil Co downward.
Since the circumferential size of the transformer Tr is not uniform, it may be elliptical, square, or even irregular, in order that the roller 61 does not collide with the transformer Tr greatly or get stuck when the transformer Tr rotates, the roller 61 is connected to the first cylinder 322 through the first flexible body 63. The first flexible body 63 may be a coil spring, a hydraulic buffer, a nitrogen spring, a silicone rubber having a large deformation amount, polyurethane, or the like, and when the shape difference of the transformer Tr is excessively large, a coil spring having a long elastic stroke is preferable. After the transformer Tr is lifted and attached to the copper foil Co by the transformer lifting part 43, the first cylinder 322 drives the roller 61 to drop and contact the copper foil Co. Of course, the first cylinder 322 may be used as a flexible body as well, and the output force of the cylinder is adjusted by adjusting the air pressure of the cylinder to realize automatic expansion and contraction of the roller 61 according to the rotation track of the transformer Tr.
Referring to fig. 9 and 10, in order to guide the copper foil Co when the copper foil Co is fed out by the copper foil feeding section 20, the copper foil feeding section further includes a plurality of copper foil auxiliary roller groups 70 provided in the feeding direction of the copper foil Co for assisting the copper foil Co to be fed out, the copper foil auxiliary roller groups 70 include a first copper foil auxiliary roller group 71, and the first copper foil auxiliary roller group 71 includes a first roller 711 and a second roller 712 provided opposite to the first roller 711 so as to sandwich the copper foil Co in a self-adjusting manner. Further, stoppers for positioning the copper foil Co are provided on both sides of the rolling surface of the first roller 711 to limit the deflection of the copper foil Co when it is fed out.
In order to adjust the optimal force when the first roller 711 and the second roller 712 clamp the copper foil Co, the second roller 712 may be provided as an adjustable type, and the adjustment may be performed using a waist-shaped hole known to those skilled in the art. Because the adhesive tape Ta is adhered to the copper foil Co, the thickness of the copper foil Co adhered with the adhesive tape Ta section is inconsistent with the thickness of the copper foil Co not adhered with the adhesive tape Ta, in order to prevent the copper foil Co adhered with the adhesive tape Ta from being broken due to clamping stagnation at the copper foil auxiliary roller set 70, a second flexible body (not shown) is further arranged on the copper foil auxiliary roller set 70, and the second roller 712 is connected to the roller mounting seat 713 through the second flexible body, so that the second roller 712 is self-adjusting according to the thickness of the copper foil Co. Similarly, the second flexible body may be a coil spring, a hydraulic buffer, a nitrogen spring, a silicone rubber having a large deformation amount, polyurethane, or the like, and since the difference between the thickness of the copper foil Co to which the gummed paper Ta segment is attached and the thickness of the copper foil Co to which the gummed paper Ta is not attached is generally 3mm or less, the second flexible body (not shown) may be selected from a silicone rubber or polyurethane having a large deformation amount. Of course, the second roller 712 itself may be made of silica gel or polyurethane.
Further, when the fed copper foil Co is long, the copper foil Co tends to deflect as it is further from the position where the copper foil Co wraps the transformer Tr, and therefore, in order to prevent deflection of the copper foil Co, a copper foil positioning block 714 having vacuum suction holes (not shown) provided in the feeding direction of the copper foil Co may be further included, and the copper foil Co may be sucked through the vacuum suction holes (not shown) of the copper foil positioning block 714 and then held by the copper foil auxiliary roller group 70. Of course, the copper foil positioning block 714 may be provided at another place, for example, after the copper foil Co passes through the auxiliary roller set, the copper foil Co may be held by the copper foil holding portion 21 by suction through a vacuum suction hole (not shown) of the copper foil positioning block 714.
In addition, some rolled copper foil Co has a layer of adhesive glue like double sided adhesive, because the copper foil Co is attached with a layer of protective layer, such as a protective film or protective paper, before use, so as to protect the adhesive glue on the surface of the copper foil Co. Also included is a protective layer recovery mechanism 80 for the protective layer of copper foil Co.

In one embodiment, the separator 81 includes a through slot 811 that allows copper foil Co to pass through. In order to reduce the friction force of the copper foil Co in the through groove 811, meanwhile, in order to facilitate the copper foil Co to pass out of the separating part 81 through the through groove 811 manually, a supporting roller 812 for supporting the copper foil Co is arranged at the lower part of the through groove 811, in order to facilitate the adjustment of the clamping force of the copper foil Co in the through groove 811, the copper foil Co can be automatically separated after being separated manually for the first time, a third flexible body 813 is arranged at the upper part of the through groove 811, the distance between the third flexible body 813 and the supporting roller 812 can be adjusted, and the third flexible body 813 can be a spring, an oil buffer, silica gel, polyurethane or the like. The distance between the third flexible body 813 and the support roller 812 can be adjusted by a screw.
The protective layer recovery unit 82 may be provided directly under the separation unit 81, or may be provided at another place under the separation unit 81, and the discarded protective layer P may be transferred to the protective layer recovery unit 82 by transfer. The protective layer recycling portion 82 may be a sheet metal welded box, a plastic box, a trash can directly placed at the lower part of the device, or the like, and may be selected by one of ordinary skill in the art according to the needs.
As the transfer of the protective layer, the fourth driving unit 83 may be provided between the separating unit 81 and the protective layer collecting unit 82 in the linear direction, or may be provided elsewhere, and the protective layer may be transported to the protective layer collecting unit 82 by driving the fourth driving unit 83 after being sent out from the separating unit 81. Since the third roller 831 and the fourth roller 832 have friction force between the second roller 712, the third roller, and the protective layer when they clamp the protective layer, the first motor 833 can realize the conveyance of the protective layer P when driving the second roller 712 or the third roller to roll. Further, the fourth driving part 83 is further provided with a first adjusting device 834 for adjusting the clamping force of the third roller 831 and the fourth roller 832 to the protective layer.
