Description

Technical Field

[0001] The utility model relates to the technical field of aerogel preparation, in particular to a gel frame cutting device. Background Art

[0002] Aerogel thermal insulation pads are widely used in new energy vehicle battery systems due to their heat insulation, fireproofing, insulation, and buffering functions. Existing aerogel thermal insulation pads usually use a plastic frame and a film to encapsulate the aerogel. Specifically, the encapsulation process is as follows: the aerogel is first pressed into the plastic frame, and then the plastic film is covered on the aerogel and the plastic frame. The plastic film covers the entire aerogel and part of the plastic frame (in contact with the aerogel). The plastic film is then hot-pressed to bond the film to the aerogel and the plastic frame. The outer portion of the plastic frame (not covered by the film) is then cut to obtain a thermal insulation pad of a preset shape.

[0003] Traditional plastic frame cutting devices consist of a lower mold structure and an upper mold structure. The upper mold structure includes a die cutter and a pre-pressed foam positioned inside the die cutter. When the plastic frame needs to be cut, the upper mold structure descends, the pre-pressed foam pressing against the non-cutting portion of the plastic frame while the die cutter cuts the portion to be cut. Because there is typically a gap between the die cutter and the pre-pressed foam, and the waste material being cut is relatively small (a small circle around the outer edge of the plastic frame), the waste material easily sticks to the die cutter and becomes trapped in the gap between the die cutter and the pre-pressed foam, making it difficult to remove.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0033] The rubber frame cutting device of this embodiment can be used to cut the rubber frame of the aerogel thermal insulation pad, so that the outermost circle of the rubber frame is cut off, so that the shape and size of the aerogel thermal insulation pad meet the design requirements.

[0034] like Figures 1 to 5As shown, the rubber frame cutting device of this embodiment mainly includes: an upper mold mechanism 2, a first drive mechanism 1, a lower mold mechanism 3 and a discharge mechanism 4. Among them, the first drive mechanism 1 can be a single-axis drive module, which is used to drive the upper mold mechanism 2 to move up and down along the Z direction; the upper mold mechanism 2 includes an upper pressure plate 21 for pressing the product to be cut (in this embodiment, it refers to the thermal insulation pad of the outer ring of the rubber frame that has not been cut). The lower mold mechanism 3 is arranged below the upper mold mechanism 2, and the lower mold mechanism 3 mainly includes a support seat 31, a cutter 32, a first stripper plate 33 and a second stripper plate 34. The cutter 32 is fixedly mounted on the support seat 31. The cutter 32 is ring-shaped. The ring-shaped cutter 32 has a relative inner side and outer side. The first stripper plate 33 is elastically connected to the support plate and is located on the inner side of the cutter 32 (ring), and the second stripper plate 34 is elastically connected to the support plate and is located on the outer side of the cutter 32 (ring). When the device is in a non-cutting state, the upper surfaces of the first stripper plate 33 and the second stripper plate 34 are higher than the upper end of the cutter 32. When the product to be cut is placed on the lower mold mechanism 3 and has not yet been subjected to downward pressure, the product to be cut contacts the upper surfaces of the first stripper plate 33 and the second stripper plate 34 but does not contact the upper end surface of the cutter 32. The discharge mechanism 4 is arranged beside the upper mold mechanism 2 and the lower mold mechanism 3, and is used to reach into the lower mold mechanism 3 after cutting is completed to grab the cut product 10 (in this embodiment, the thermal insulation pad whose outer ring of the rubber frame has been cut) and the waste material 20 (in this embodiment, the cut outer ring of the rubber frame) and discharge both from the lower mold mechanism 3.

[0035] By adopting the above scheme, when it is necessary to cut the product to be cut, the product to be cut is first placed on the lower mold mechanism 3, and the product to be cut contacts the upper surface of the first stripping plate 33 and the second stripping plate 34. The first driving mechanism 1 drives the upper mold mechanism 2 to move downward, and the upper pressure plate 21 of the upper mold mechanism 2 contacts the product to be cut and presses it downward. The first stripping plate 33 and the second stripping plate 34 are also pressed downward to the preset position until the outer ring of the rubber frame of the product to be cut is cut off by the cutter 32. The first driving mechanism 1 drives the upper mold mechanism 2 to move upward, and the first stripping plate 33 pushes the cut product 10 upward during the resetting process, and the second stripping plate 34 pushes the waste material 20 upward during the resetting process. The discharging mechanism 4 removes the cut product 10 and the waste material 20 that are pushed up at the same time from the lower mold mechanism 3.

[0036] During the above-mentioned cutting and discharging process, since the first stripping plate 33 and the second stripping plate 34 are elastically connected to the support plate through elastic connectors, the impact force of the upper mold mechanism 2 on the product to be cut when it is pressed down can be buffered. Therefore, the first stripping plate 33 and the second stripping plate 34 can be made of steel plates instead of the traditional pre-pressed foam design, which can avoid the problem that the gap with the cutter 32 becomes larger due to deformation of the pre-pressed foam during the stripping process, thereby causing the waste 20 to be drawn into the gap, reducing the difficulty of discharging the waste 20 and improving production efficiency and yield.

[0037] like Figures 4 to 6 As shown, the device of this embodiment also includes a base 36 and a movable plate 35. Among them, the support base 31 of the lower mold mechanism 3 is fixedly mounted on the base 36, the movable plate 35 is elastically connected to the base 36 through an elastic connector, and the second stripper plate 34 is fixedly connected to the movable plate 35. Furthermore, the cutter 32 and the support base 31 can be integrally formed by machining a steel block, and the cutter 32 divides the upper surface of the support base 31 into two inner and outer areas. The inner area is used to elastically connect with the first stripper plate 33, and the outer area is used to abut against the second stripper plate 34 when the second stripper plate 34 moves downward to limit and support it. By installing the second stripper plate 34 on the movable plate 35 and then elastically connecting it to the base 36 through the movable plate 35, the installation of the second stripper plate 34 can be facilitated and its installation strength can be improved.

[0038] like Figure 4 As shown, the movable plate 35 of this embodiment is provided with an X positioning mechanism for positioning the product to be cut along the X direction. Specifically, the X positioning mechanism includes a first positioning plate 51, a first power source 52, and a second positioning plate 53. Among them, the first positioning plate 51 is fixed on the movable plate 35 and serves as a positioning reference. The first positioning plate 51 is located on one side of the product to be cut along the X direction; the first power source 52 is installed on the movable plate 35 and is located on the other side of the product to be cut along the X direction, and the second positioning plate 53 is connected to the output shaft of the first power source 52. When the product to be cut is placed on the first stripper plate 33 and the second stripper plate 34, the first power source 52 drives the second positioning plate 53 to move along the X direction, so that the product to be cut can be accurately positioned in the X direction.

[0039] Continue to refer to Figure 4 As shown, the movable plate 35 of this embodiment is also provided with a Y-direction positioning mechanism for positioning the product to be cut along the Y direction. The Y-direction positioning mechanism includes a second power source 54 and a third power source 55, each of which is connected to the movable plate 35 and distributed along the Y direction on either side of the product to be cut. A third positioning plate 56 is connected to the output shaft of the second power source 54, and a fourth positioning plate 57 is connected to the output shaft of the third power source 55. The third positioning plate 56 and the fourth positioning plate 57 work together to position the product to be cut along the Y direction, accurately positioning it on the first stripper plate 33 and the second stripper plate 34.

[0040] like Figure 7As shown, the discharge mechanism 4 of this embodiment includes a second drive mechanism (not shown), a third drive mechanism 41, and a pick-up plate 42. The third drive mechanism 41 is connected to the output shaft of the second drive mechanism, and the pick-up plate 42 is connected to the output shaft of the third drive mechanism 41. Specifically, the second drive mechanism can be a single-axis drive module for driving the third drive mechanism 41 in the X or Y direction, and the third drive mechanism 41 can be a single-axis drive module for driving the pick-up plate 42 in the Z direction. The pick-up plate 42 is connected to a suction unit connected to a negative pressure system for sucking in the cut products 10 and waste 20. When the cut products 10 and waste 20 need to be discharged, the second drive mechanism drives the third drive mechanism 41 and the pick-up plate 42 in the X or Y direction (in this embodiment, in the X direction) to move above the lower mold mechanism 3. Subsequently, the third drive module drives the pick-up plate 42 to descend until the suction unit can suck in the cut products 10 and waste 20.

[0041] like Figure 7 As shown, the suction unit of this embodiment includes a mounting plate 43 and a plurality of suction cups connected to the mounting plate 43 (not shown, connected to the side of the mounting plate 43 facing the product), wherein the mounting plate 43 is used to be connected to the material removal plate 42, and the plurality of suction cups are respectively connected to the negative pressure system to suck the cut products 10. A fourth power source 44 can also be connected to the mounting plate 43 of the suction unit, and two fourth power sources 44 are respectively connected to the two ends of the mounting plate 43 along the Y direction. A clamping jaw 45 is connected to the output shaft of each fourth power source 44. When the output shafts of the two fourth power sources 44 are retracted, the two clamping jaws 45 can move toward each other, thereby clamping the waste material 20 on the cut product 10 along the Y direction. The above solution can ensure that the waste material 20 can be discharged together with the cut product 10, and prevent the waste material 20 from falling during the discharge process.

[0042] Further, if Figure 7 As shown, the discharge mechanism 4 of this embodiment also includes a fixed plate 46, a fifth power source (not shown, located below the fixed plate 46), and a third stripper plate 47. The fixed plate 46 is connected to the top of the feed plate 42, the fifth power source is mounted on the feed plate 42, and the third stripper plate 47 is connected to the output shaft of the fifth power source. The third stripper plate 47 is also connected to the fixed plate 46 via a guide to improve the stability of the movement. When the fifth power source drives the third stripper plate 47 downward, the third stripper plate 47 can push the waste material 20 to help the waste material 20 smoothly separate from the cut product 10.

[0043] In this embodiment, the first power source 52 , the second power source 54 , the third power source 55 , the fourth power source 44 and the fifth power source may be pneumatic cylinders or electric cylinders, etc.

[0044] The working process of the device of this embodiment is as follows: the product to be cut is placed on the lower mold mechanism 3. At this time, the product to be cut is in contact with the first stripper plate 33 and the second stripper plate 34 but has not yet contacted the cutter 32. The first power source 52, the second power source 54 and the third power source 55 respectively drive the corresponding positioning plates to position the product to be cut; the first drive mechanism 1 drives the upper mold mechanism 2 to descend to press the product to be cut, the first stripper plate 33 and the second stripper plate 34 downward to a preset position. After the cutting is completed, the first drive mechanism 1 drives the upper mold mechanism 2 to move upward, and the first stripper plate 33 and the second stripper plate 34 are released due to the pressure they are subjected to. During the resetting process, the corresponding cut products 10 and waste materials 20 are respectively lifted up; the second drive mechanism and the third drive mechanism 41 respectively drive the suction unit to move to suck the cut products 10 and the waste materials 20. At the same time, the fourth power source 44 drives the clamping jaw 45 to move to press the waste materials 20 onto the cut products 10; after the suction unit moves the material to the preset position, the fourth power source 44 drives the clamping jaw 45 to move to release the waste materials 20, and the fifth power source drives the third stripping plate 47 to move to push the waste materials 20 away from the cut products 10. Subsequently, the discharging mechanism 4 moves the cut products 10 to the next workstation.

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.
