[0038] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0039] like Figure 1As shown, the cutting machine of this embodiment mainly includes: a frame 1, a first cutting mechanism 2, a first detection mechanism 3, a stripping mechanism 4, a removal mechanism 5 and a Teflon conveyor belt 6. Among them, the frame 1 is used as the main frame of the cutting machine for installing and supporting the above-mentioned mechanisms; the Teflon conveyor belt 6 is used to transmit materials between the first cutting mechanism 2, the first detection mechanism 3, the stripping mechanism 4 and the removal mechanism 5. Of course, the cutting machine of this embodiment also includes an electric control system for electrically connecting with the first cutting mechanism 2, the first detection mechanism 3, the stripping mechanism 4, the removal mechanism 5 and the Teflon conveyor belt 6.

[0040] Specifically, if Figure 2 As shown, the first cutting mechanism 2 includes a first lower template 21, a first cutter 22 and a three-axis driving module 23. The first lower template 21 and the three-axis driving module 23 are connected to the frame 1, the first cutter 22 is connected to the three-axis driving module 23 and is located above the first lower template 21, and the first cutter 22 is used to cut the glue running on the first lower template 21 into blank strips and waste. More specifically, the three-axis driving module 23 includes a Z-axis driving assembly 231, an X-axis driving assembly 233 and a Y-axis driving assembly 232, and the Z-axis driving assembly 231, the X-axis driving assembly 233 and the Y-axis driving assembly 232 are respectively used to drive the first cutter 22 to move along the Z-axis, the X-axis (parallel to the conveying direction of the Teflon conveyor belt 6) and the Y-axis (perpendicular to the conveying direction of the Teflon conveyor belt 6). The blank strip in this embodiment refers to a plurality of product blanks that have not yet been cut into single blanks and a plurality of blanks are still connected in a strip shape. The first detection mechanism 3 is arranged at the discharge end of the first cutting mechanism 2, and is used to detect the blade position of the blank belt and / or waste material cut by the first cutting mechanism 2. When the first detection mechanism 3 detects that the blade position is deviated, the information is fed back to the electronic control system, and the electronic control system controls the X-axis drive component 233 and / or the Y-axis drive component 232 to drive the first cutter 22 to move along the X-axis and / or the Y-axis, so as to correct the position of the first cutter 22 and compensate for the blade position. The stripping mechanism 4 is arranged at the discharge end of the first detection mechanism 3, and is used to strip the blank belt and waste material from the Teflon conveyor belt 6, so that the blank belt and waste material are pre-separated from the Teflon conveyor belt 6. The pre-separation described in this embodiment means that the blank belt and waste material are temporarily separated from the Teflon conveyor belt 6 and then return to the Teflon conveyor belt 6. This step is to reduce the bonding force between the blank belt and waste material and the Teflon conveyor belt 6, so as to facilitate the removal mechanism 5 in the subsequent process to separate the waste material from the Teflon conveyor belt 6. The removal mechanism 5 is disposed on the frame 1 and is used to grab the waste material stripped by the stripping mechanism 4 from the Teflon conveyor belt 6 and place the waste material in a waste material storage box.

[0041] With the above structure, the cutting machine of this embodiment has the following advantages:

[0042] 1. The cutting machine of this embodiment detects the position of the blade on the previous material (blank and scrap) discharged from the first cutting mechanism 2 through the first detection mechanism 3. The first detection mechanism 3 transmits the blade position information to the electronic control system. The electronic control system controls the X-axis drive component 233 and / or the Y-axis drive component 232 of the three-axis drive module 23 according to the received information to drive the first cutter 22 to move along the X-direction and / or the Y-direction, so as to correct the position of the first cutter 22, and then cut the next product from the newly fed material onto the first lower template 21, thereby greatly improving the accuracy of cutting materials.

[0043] 2. Since the glue is relatively soft, in order to avoid deformation of the glue due to lack of support during the cutting process, thereby affecting the cutting accuracy, the first lower template 21 is not provided with a hollow waste discharge port, so that the first lower template 21 can fully support the glue during the cutting process, and then a removal mechanism 5 is provided at the discharge end of the first cutting mechanism 2 to remove the waste, and the stripping mechanism 4 provided between the removal mechanism 5 and the first cutting mechanism 2 can reduce the adhesion between the waste and the Teflon conveyor belt 6, so as to facilitate the removal mechanism 5 to grab the waste.

[0044] Combination Figure 1 and Figure 2 As shown, the first detection mechanism 3 of this embodiment includes a first bracket 31 and a first industrial camera 32. The first bracket 31 is installed on the frame 1, and the first industrial camera 32 is connected to the first bracket 31, and is used to detect the blade position of the blank strip or waste material discharged from the first cutting mechanism 2, and transmit the position information to the electronic control system.

[0045] Combination Figure 3 and Figure 4As shown, the stripping mechanism 4 of this embodiment includes a second bracket 41, a first support plate 42, a second support plate 43 and a rotating shaft 44. Among them, the second bracket 41 is connected to the frame 1 to install the first support plate 42, the second support plate 43 and the rotating shaft 44; the first support plate 42 and the second support plate 43 are installed on the second bracket 41 at intervals, and the first support plate 42 is located on the side of the second support plate 43 close to the first detection mechanism 3; the rotating shaft 44 is rotatably connected to the second bracket 41 and is located below the first support plate 42 and the second support plate 43. Along the direction from the feeding end to the discharging end of the stripping mechanism 4, the Teflon conveyor belt 6 is connected to the first support plate 42, the rotating shaft 44 and the second support plate 43 in sequence. Specifically, the Teflon conveyor belt 6 passes over the first support plate 42, then goes around to the bottom of the rotating shaft 44, and then passes over the second support plate 43. Preferably, the rotating shaft 44 is located directly below the gap between the first supporting plate 42 and the second supporting plate 43, and the gap between the first supporting plate 42 and the second supporting plate 43 is smaller than the diameter of the rotating shaft 44. Furthermore, the gap between the first supporting plate 42 and the second supporting wall is between 2 and 5 mm, which can ensure the smooth movement of the Teflon conveyor belt 6 while preventing the blank belt and waste from deforming downward due to lack of support for a long time and a long distance.

[0046] By adopting the above scheme, when the blank belt and waste material run to the gap between the first support plate 42 and the second support plate 43 along with the Teflon conveyor belt 6, the Teflon conveyor belt 6 is temporarily separated from the blank belt and waste material when it goes downward to the bottom of the rotating shaft 44, so that the bonding force between the blank belt and waste material discharged from the first cutting mechanism 2 and the Teflon conveyor belt 6 can be reduced. When the blank belt and waste material run to the second support plate 43 along with the Teflon conveyor belt 6, the removal mechanism 5 can easily grab the waste material from the Teflon conveyor belt 6.

[0047] like Figure 5 As shown, one end of the first support plate 42 facing the second support plate 43 and one end of the second support plate 43 facing the first support plate 42 are provided with rounded corners, which can prevent the Teflon conveyor belt 6 from being easily worn.

[0048] Combination Figures 4 to 6As shown, a plurality of first through holes 431 are provided on the second support plate 43 of the present embodiment. A bottom plate 45 is also connected to the bottom of the second support plate 43, and a groove 451 is provided on the side of the bottom plate 45 facing the second support plate 43, and the groove 451 is connected to the plurality of first through holes 431, that is, the opening size of the groove 451 can cover the distribution area of ​​the plurality of first through holes 431. A second through hole 452 connected to the groove 451 is provided on the bottom plate 45, and the second through hole 452 is used to connect to the negative pressure system. With the above scheme, when the removal mechanism 5 is to grab the waste on the Teflon conveyor belt 6, the negative pressure system evacuates the groove 451, so that a negative pressure is formed in the groove 451, so as to suck the Teflon conveyor belt 6 and prevent the Teflon conveyor belt 6 from moving upward with the removal mechanism 5.

[0049] Furthermore, the stripping mechanism 4 of this embodiment may also include two cylinders 46, which are distributed on both sides of the second support plate 43 perpendicular to the transmission direction of the Teflon conveyor belt 6. The two cylinders 46 are respectively connected to the second bracket 41, and a pressing plate 47 is also connected to the output shaft of each cylinder 46. The pressing plate 47 is used to press the Teflon conveyor belt 6 when the removal mechanism 5 grabs the waste material, so as to prevent the Teflon conveyor belt 6 from moving along the Z-axis direction.

[0050] like Figure 7 As shown, the removal mechanism 5 of this embodiment includes a third bracket 51, a multi-axis driving module 52 and a suction module 53. The third bracket 51 is connected to the frame 1, and the multi-axis driving module 52 is connected to the third bracket 51. The multi-axis driving module 52 is used to drive the suction module 53 connected thereto to move along the Z axis and the Y axis (perpendicular to the conveying direction of the Teflon conveyor belt 6). The suction module 53 includes a suction cup connected to the negative pressure system, and the waste is grasped by the suction cup.

[0051] Combination Figure 8 and Fig. 9 As shown, the cutting machine of this embodiment further includes a second cutting mechanism, which is arranged at the discharge end of the removal mechanism 5 and is used to cut and separate the multiple blanks on the blank belt. The second cutting mechanism includes a fourth bracket 71, a single-axis driving module arranged on the fourth bracket 71, a second cutter 73 connected to the single-axis driving module, and a second lower template 74 connected to the fourth bracket 71, and the second lower template 74 is located below the second cutter 73 and below the Teflon conveyor belt 6.

[0052] Key References Fig. 9The single-axis drive module of this embodiment includes a motor (not shown), a screw rod 721, a nut seat 722, a first connecting block 723, a second connecting block 724, a limit block 725, a guide rod (located in the first connecting block 723 and the limit block 725, not shown in the figure) and a spring 726. Among them, the screw rod 721 is rotatably connected to the fourth bracket 71 through a bearing, and one end of the screw rod 721 is connected to the motor; the nut seat 722 is connected to the screw rod 721, and is used to install the first connecting block 723 and can drive the first connecting block 723 to move; the guide rod is passed through the first connecting block 723, the lower end of the guide rod is connected to the second connecting block 724, and the upper end of the guide rod is connected to the limit block 725, and the guide rail can move up and down relative to the first connecting block 723; the spring 726 is sleeved on the guide rod and is located between the first connecting block 723 and the second connecting block 724, so as to realize the elastic connection between the second connecting block 724 and the first connecting block 723; the second cutter 73 is rotatably connected to the second connecting block 724. By adopting the above scheme, during installation, the Z-axis position of the second cutter 73 is determined so that the second cutter 73 contacts the second lower template 74, and then the first connecting block 723 is fixed on the nut seat 722. When the blank strip needs to be cut, the motor drives the screw rod 721 to rotate to drive the nut seat 722 to move. The second cutter 73 in contact with the second lower mold seat rotates under the action of friction to cut the blank strip. Since the second cutter 73 is in rolling contact with the first lower template 21 (and the Teflon conveyor belt 6 thereon), the Teflon conveyor belt 6 will not be cut.

[0053] Furthermore, the blade thickness of the second cutter 73 is between 1.0 and 1.1 mm. In other words, the thickness of the disc-shaped second cutter 73 is between 1.0 and 1.1 mm. This thickness can ensure that the second cutter 73 reduces the risk of cutting the Teflon conveyor belt 6 while meeting the requirements of cutting the blank.

[0054] Combination Figure 1 and Figure 8 As shown, the cutting machine of this embodiment further includes a second industrial camera disposed on the fourth bracket 71, and the second industrial camera is used to detect whether there is any waste material on the blank belt discharged from the self-removing mechanism 5. In other words, the second industrial camera is used to detect whether the waste material is removed in the previous process.

[0055] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
