AI Technical Summary
During the peeling process of copper clad laminates, the film and substrate are easily damaged, mainly because the small peeling angle requires a large force, resulting in the film and substrate being subjected to great stress and thus damaged.
A copper clad laminate peeling mechanism was designed. By setting first, second and third peeling rollers, the peeling angle between the film and the substrate is controlled to be 170 degrees-180 degrees. The film and the substrate are guided to the winding structure by guide roller group. Chain drive or synchronous belt drive is used to ensure that the rollers rotate synchronously and reduce uneven friction.
It improves the peeling efficiency between the film and the substrate, reduces the risk of damage, and makes the peeling process smoother and the synchronous movement of the film and the substrate more stable.

Abstract
Description
Technical Field
[0001] This utility model relates to copper clad laminate stripping equipment, and particularly to a copper clad laminate stripping mechanism. Background Technology
[0002] Copper clad laminate (CCL) peeling equipment is used to peel CCLs apart into film and substrate. The unpeeled CCL is in rolls, while the peeled film and substrate also need to be rolled separately. A typical CCL peeling mechanism includes: an unwinding structure for unwinding the CCL, a set of guide rollers, a first winding structure for winding the film, and a second winding structure for winding the substrate. The CCL is peeled apart on one of the guide rollers, separating into film and substrate. The film and substrate are then guided by the guide rollers and connected to the first and second winding structures, respectively.
[0003] Existing copper clad laminate peeling mechanisms still have problems: the strength of both the film and the substrate is relatively low, and they are easily damaged during the film peeling process, especially at the point where the film and substrate are separated.
[0004] The applicant discovered that the reason why the membrane and substrate are easily damaged during the membrane peeling process is that the peeling angle of the membrane and substrate is relatively small, which requires a large force to peel them apart. The membrane and substrate are easily damaged when subjected to large forces. Utility Model Content

[0038] Please see Figure 1 A copper clad laminate stripping mechanism includes: an unwinding structure 1, an equipment frame 2, a first winding structure 3, and a second winding structure 4.
[0039] The unwinding structure 1 is used to unwind the copper-clad laminate 9. More specifically, the unwinding structure 1 can be set with reference to existing unwinding structures.
[0040] Please see Figure 1 and Figure 3 The equipment frame 2 is rotatably connected to a first guide roller group, a peeling roller group 6, a second guide roller group, and a third guide roller group. More specifically, the equipment frame 2 has two horizontally opposite vertical side plates 2a, and the two ends of any one of the rollers in the first guide roller group, the peeling roller group 6, the second guide roller group, and the third guide roller group are rotatably connected to the two vertical side plates 2a through bearing seats.
[0041] The first guide roller group consists of several first guide roller bodies 5.
[0042] The stripping roller assembly 6 includes: a first stripping roller 61 for the copper-clad laminate 9 to pass through, a second stripping roller 62 for the film 91 to pass through, and a third stripping roller 63 for the substrate 92 to pass through.
[0043] The first guide roller group guides the copper-clad laminate 9 unwound from the unwinding structure 1 into the stripping roller group 6. The stripping roller group 6 is used to separate the substrate 92 and the film 91 of the copper-clad laminate 9. The second guide roller group guides the stripped film 91. The third guide roller group guides the stripped substrate 92.
[0044] The relative positions of the first peeling roller 61, the second peeling roller 62, and the third peeling roller 63 are designed, and the copper-clad laminate 9, the peeled substrate 92, and the peeled film 91 are designed to pass through the first peeling roller 61, the second peeling roller 62, and the third peeling roller 63 respectively, so that the peeling angle between the substrate 92 and the film 91 is 170 degrees to 180 degrees. That is, the angle between the film 91 between the second peeling roller 62 and the second guide roller group, and the angle between the substrate 92 between the third peeling roller 63 and the third guide roller group is 170 degrees to 180 degrees.
[0045] Please see Figure 3 In some embodiments, the peeling roller 62 contacts the outer side of the substrate 92 away from the film 91, the second peeling roller 62 contacts the outer side of the film 91 away from the substrate 92, and the third peeling roller 63 contacts the inner side of the substrate 92 close to the film 91. That is, the distance between the second peeling roller 62 and the third peeling roller 63 is relatively large, the copper clad laminate 9 enters the bottom of the second peeling roller 62, and the peeling position where the film 91 and the substrate 92 begin to peel is at the bottom of the second peeling roller 62.
[0046] Furthermore, the top of the first stripping roller 61, the bottom of the second stripping roller 62, and the bottom of the third stripping roller 63 are horizontally aligned.
[0047] Both the membrane 91 and the substrate 92 are relatively thin. The section of substrate 92 corresponding to the top of the first peeling roller 61, the bottom of the second peeling roller 62, and the bottom of the third peeling roller 63 is horizontal, which is more conducive to the membrane 91 being peeled off from the substrate 92.
[0048] Please see Figure 4 In some embodiments, the first peeling roller 61 contacts the outer side of the substrate 92 away from the film 91, the second peeling roller 62 contacts the outer side of the film 91 away from the substrate 92, and the third peeling roller 63 contacts the outer side of the substrate 92 away from the film 91. That is, the distance between the second peeling roller 62 and the third peeling roller 63 is relatively small. Combined with the thickness of the copper clad laminate 9, the copper clad laminate 9 enters between the second peeling roller 62 and the third peeling roller 63, and the peeling position where the film 91 and the substrate 92 begin to peel off is between the second peeling roller 62 and the third peeling roller 63.
[0049] Please see Figure 2 Both the first winding structure 3 and the second winding structure 4 are mounted on the equipment frame 2. The second guide roller group guides the peeled film 91, which is connected to the first winding roller body 31 of the first winding structure 3, and the third guide roller group guides the peeled substrate 92, which is connected to the second winding roller body 41 of the second winding structure 4.
[0050] The first winding structure 3 and the second winding structure 4 have the same structure and can be set with reference to the existing unwinding structure 1. More specifically, one can be selected from the existing center winding type and contact winding type winding methods.
[0051] For the center-rewind type, the first winding roller 31 of the first winding structure 3 and the second winding roller 41 of the second winding structure 4 are both directly driven by a motor. Correspondingly, the motor is equipped with a magnetic powder clutch to adjust the speed and torque according to the amount of material wound by the first winding roller 31 / second winding roller 41, and the unwinding structure 1 is equipped with a magnetic powder brake.
[0052] For contact winding type, the equipment frame 2 is rotatably connected to a first contact roller 2b for contact with the first take-up roller 31 and a second contact roller 2c for contact with the second take-up roller 41. The equipment frame 2 is also equipped with a motor, which drives the first contact roller 2b and the second contact roller 2c to rotate synchronously. More specifically, the first contact roller 2b and the second contact roller 2c can be driven by a synchronous belt, with the motor directly driving either the first contact roller 2b or the second contact roller 2c to rotate. That is, the first take-up roller 31 and the second take-up roller 41 rotate through friction transmission. As material is wound onto the first take-up roller 31 / second take-up roller 41, it contacts the first contact roller 2b / second contact roller 2c, and the roll diameter increases accordingly, while the winding linear speed remains constant. Correspondingly, the unwinding structure 1 is equipped with a magnetic powder brake.
[0053] In some embodiments, the first winding structure 3 and the second winding structure 4 are preferably contact winding types.
[0054] The contact winding method ensures that the linear speed of the film 91 and the substrate 92 is constant, which is more suitable for the scenario where the film 91 and the substrate 92 move synchronously at the peeling position of the copper clad laminate 9, and is more conducive to the peeling of the film 91 and the substrate 92.
[0055] More specifically, for the first winding structure 3 and the second winding structure 4 using contact winding, taking the first winding structure 3 as an example, it can include: a swing arm 32 and a cylinder 33; the swing arm 32 consists of a connecting shaft 321 rotatably connected to the equipment frame 2 and two arm bodies 322 fixed to the connecting shaft 321, and the first winding roller body 31 is detachably connected to the two arm bodies 322; there can be two cylinders 33, with the cylinder bodies respectively hinged to the two vertical side plates 2a of the equipment frame 2, and the piston rods respectively hinged to the two arm bodies 322; the cylinder 33 can be a pre-retractable single-acting cylinder 33, which uses gravity and the action of the spring inside the cylinder to keep the first winding roller body 31 in contact with the first contact roller body 2b. After the first winding roller body 31 winds up a suitable amount of film 91, the piston rod extends to separate the first winding roller body 31 and the first contact roller body 2b.
[0056] Please see Figure 3 and Figure 4 In some embodiments, the second guide roller group is a single second guide roller body 7; the third guide roller group is two third guide roller bodies 8.
[0057] Whether it is the embodiment in which "the peeling roller contacts the outer side of the substrate 92 away from the film 91, the second peeling roller 62 contacts the outer side of the film 91 away from the substrate 92, and the third peeling roller 63 contacts the inner side of the substrate 92 near the film 91", or the embodiment in which "the peeling roller contacts the outer side of the substrate 92 away from the film 91, the second peeling roller 62 contacts the outer side of the film 91 away from the substrate 92, and the third peeling roller 63 contacts the outer side of the substrate 92 away from the film 91", the envelope angle of the film 91 on the second peeling roller 62 is relatively large, while the envelope angle of the substrate 92 on the third peeling roller 63 is relatively small.
[0058] Therefore, the second guide roller group consists of one second guide roller 7, such that the envelope angle of the film 91 on the second guide roller 7 is approximately equal to the envelope angle of the substrate 92 on the third peeling roller 63; the third guide roller group consists of two third guide rollers 8, such that the sum of the envelope angles of the substrate 92 on the two third guide rollers 8 is approximately equal to the envelope angle of the film 91 on the second peeling roller 62. This ensures that the frictional forces experienced by the film 91 and the substrate 92 from peeling to winding are approximately the same, which better suits the scenario where the copper-clad laminate 9 moves synchronously with the film 91 and the substrate 92 at the peeling position, and is more conducive to the peeling of the film 91 and the substrate 92.
[0059] In addition, for the first winding structure 3 and the second winding structure 4 which adopt contact winding, although the contact position of the first winding roller 31 at the first contact roller 2b and the contact position of the second winding roller 41 at the second contact roller 2c will change during the winding process, the change range is very small, and the envelope angle of the film 91 at the first contact roller 2b can be kept approximately equal to the envelope angle of the substrate 92 at the second contact roller 2c.
[0060] Please see Figure 5 and Figure 6 In some embodiments, a chain drive pair is provided between the first peeling roller 61, the second peeling roller 62, and the third peeling roller 63. More specifically, a sprocket 101 is fixed to one end of each of the first peeling roller 61, the second peeling roller 62, and the third peeling roller 63, and two sprockets 101 are rotatably connected to the vertical side plate 2a of the equipment frame 2, with a chain 102 tensioned on these five sprockets 101.
[0061] In the embodiment where "the first peeling roller 61 contacts the outer side of the substrate 92 away from the film 91, the second peeling roller 62 contacts the outer side of the film 91 away from the substrate 92, and the third peeling roller 63 contacts the inner side of the substrate 92 close to the film 91", the second peeling roller 62 and the third peeling roller 63 rotate in the same direction, and the corresponding two sprockets 101 are inside the chain 102. The first peeling roller 61 rotates in the opposite direction, and the corresponding sprocket 101 is outside the chain 102.
[0062] In the embodiment where "the peeling roller 62 contacts the outer side of the substrate 92 away from the film 91, the second peeling roller 62 contacts the outer side of the film 91 away from the substrate 92, and the third peeling roller 63 contacts the outer side of the substrate 92 away from the film 91", the first peeling roller 61 and the third peeling roller 63 rotate in the same direction, and the corresponding two sprockets 101 are inside the chain 102. The second peeling roller 62 rotates in the opposite direction, and the corresponding sprocket 101 is outside the chain 102.
[0063] By using a chain drive pair to keep the rotational speeds of the first stripping roller 61, the second stripping roller 62, and the third stripping roller 63 the same, it is more in line with the scenario where the copper clad laminate 9 moves synchronously between the film 91 and the substrate 92 at the stripping position, which is more conducive to the stripping of the film 91 and the substrate 92.
