[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

In order to avoid unnecessary repetition, various possible combinations of various specific technical features in the present application are not described again.

[0027] In the following description, the terms "first, second, …" are only to distinguish different objects, and do not mean that there is the same or relationship between the objects. It should be understood that the orientation description "upper", "lower", "outer", "inner" is the orientation in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which can be the left and right directions in the normal use state or not.

[0028] It should be noted that the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitation, the element defined by the sentence "includes one" does not exclude the presence of another identical element in the process, method, article or device including the element.

[0030] The embodiments of the present application provide a perforating device for perforating structures such as polymer films, paper and any other suitable structures.

[0031] As an example, the perforating device is used to perforate the body shielding film of a vehicle. Specifically, after the body is color sprayed, it needs to be dried in an oven, and after drying, it needs to be cooled. Since the body shielding film wraps the body, the cooling speed is reduced, which reduces the production rhythm. Therefore, the body shielding film needs to be perforated in some areas (such as the window area) to accelerate heat dissipation. In the related art, the above perforation is mainly completed manually, which is low in efficiency. The perforating device of the embodiments of the present application is expected to realize high-efficiency automatic perforation.

[0032] Reference Figures 1-4 The opening device of the embodiment of the present application comprises a cutter 1, a guide assembly 2 and a first power member 3.

[0033] The cutter 1 comprises two cutter arms 11 extending along a first direction, the cutter arms 11 have a cutting edge part 11a on one side along a second direction, the cutting edge part 11a extends along the first direction, the cutting edge parts 11a of the two cutter arms 11 are arranged away from each other, and the first direction intersects the second direction.

[0034] As an example, the first direction is perpendicular to the second direction.

[0035] As an example, the cutter arm 11 is in a sheet structure, and the thickness direction of the cutter 1 is a third direction, and here, the third direction is perpendicular to both the first direction and the second direction.

[0036] The cutting edge part 11a specifically refers to a sharp side of the cutter arm 11 for cutting, and as an example, the cutter arm 11 has a cutting back part 11b on the other side along the second direction. In the embodiment, the two cutting edge parts 11a are arranged away from each other along the second direction, that is, the two cutting edge parts 11a are respectively located on the opposite two side outer surfaces of the cutter 1 along the second direction.

[0037] At least one cutter arm 11 of the cutter 1 is movably connected with the guide assembly 2, and the first power member 3 is used to drive the cutter arm 11 to move along the guide assembly 2 so as to make the cutting edge parts 11a of the two cutter arms 11 approach or move away from each other along the second direction.

[0038] The specific structural form of the guide assembly 2 is not limited, as long as the cutter arm 11 can move along the guide assembly 2 to realize that the cutting edge parts 11a of the two cutter arms 11 approach or move away from each other along the second direction. The movable connection between the cutter arm 11 and the guide assembly 2 can be sliding connection, or any other suitable form of connection. As an example, the guide assembly 2 has a sliding groove, and the cutter arm 11 is in sliding fit with the sliding groove. There can be only one cutter arm 11 movably connected with the guide assembly 2, or both of the two cutter arms 11 can be movably connected with the guide assembly 2.

[0039] The specific structural form of the first power member 3 is not limited, and as an example, the first power member 3 can comprise a motor 61, an electric cylinder, a pneumatic cylinder, an oil cylinder or any other structure capable of outputting power, and the above structure can be in transmission connection with the cutter arm 11 to realize the movement of the cutter arm 11 along the guide assembly 2. The specific implementation mode of the transmission connection can be determined according to the specific mode of the movable connection between the cutter arm 11 and the guide assembly 2, and no limitation is made thereto.

[0040] It can be understood that when the blade portions 11a of the two cutter arms 11 move away from each other along the second direction under the driving of the first power member 3, the blade portions 11a will cut open the target structure (for example, a vehicle body covering film) along the second direction, thereby realizing automatic hole opening of the target structure and improving hole opening efficiency. After the hole opening is completed, the blade portions 11a of the two cutter arms 11 can move close to each other along the second direction under the driving of the power member, in preparation for the next hole opening.

[0041] In some embodiments, referring to Figure 1 and Figure 2 , the cutter arm 11 has a cutter tip portion 11c at one end along the first direction and a connecting portion 11d at the other end, the blade portion 11a is connected to the cutter tip portion 11c, and the connecting portion 11d is connected to the guide assembly 2.

[0042] It can be understood that since the blade portions 11a of the two cutter arms 11 are arranged away from each other along the second direction, and the blade portions 11a extend to the cutter tip portions 11c, the cutter tip portions 11c of the two cutter arms 11 are also arranged away from each other along the second direction. This arrangement makes it easier for the cutter tip portions 11c to pierce the target structure, thereby improving hole opening efficiency and success rate.

[0043] In this embodiment, the connecting portion 11d is used to connect to the guide assembly 2, and the specific structure of the connecting portion 11d can be determined according to the connection mode to be achieved, which is not limited.

[0044] In some embodiments, referring to Figure 1 and Figure 2 , the guide assembly 2 has two first sliding grooves 21 distributed along the second direction, the two cutter arms 11 are respectively in sliding fit with the two first sliding grooves 21, the first sliding groove 21 has a starting end 21a and a terminal end 21b, the starting end 21a and the terminal end 21b are distributed along the first direction, and the distance between the starting ends 21a of the two first sliding grooves 21 along the second direction is smaller than the distance between the terminal ends 21b of the two first sliding grooves 21 along the second direction. The connecting portion 11d is in sliding fit with the first sliding groove 21, and the connecting portion 11d is located on the side close to the starting end 21a, and the cutter tip portion 11c is located on the side close to the terminal end 21b.

[0045] Here, the starting end 21a and the terminal end 21b respectively refer to the two ends of the first sliding groove 21 in the extension direction, and the specific extension mode of the two first sliding grooves 21 is not limited.

[0046] As an example, referring to Figure 1 and Figure 2, the extension directions of at least part of the groove sections of the two first sliding grooves 21 intersect, so that the starting ends 21a and the terminal ends 21b are distributed along the first direction, and the interval between the starting ends 21a of the two first sliding grooves 21 along the second direction is smaller than the interval between the terminal ends 21b of the two first sliding grooves 21 along the second direction. More specifically, along the direction from the starting end 21a to the terminal end 21b, the first sliding groove 21 comprises a first linear section 21c, an inclined section 21d and a second linear section 21e, the first linear section 21c and the second linear section 21e extend along the first direction, and the extension directions of the inclined sections 21d of the two first sliding grooves 21 intersect.

[0047] As another example, along the direction from the starting end 21a to the terminal end 21b, the first sliding groove 21 can comprise a first section and a second section, the first section extends along the first direction, and the second section extends along the second direction, that is, the first sliding groove 21 can be substantially in the shape of a broken line, so that the starting ends 21a and the terminal ends 21b are distributed along the first direction, and the interval between the starting ends 21a of the two first sliding grooves 21 along the second direction is smaller than the interval between the terminal ends 21b of the two first sliding grooves 21 along the second direction.

[0048] It can be understood that the interval between the terminal ends 21b of the two first sliding grooves 21 along the second direction determines the maximum opening of the cutter arms 11 (the maximum distance between the blade parts 11a of the two cutter arms 11 along the second direction), in the embodiment, the interval between the terminal ends 21b of the two first sliding grooves 21 along the second direction can be determined according to the actual use requirement (the range actually required to be punched), and the present application is not limited in this regard.

[0049] The interval between the starting ends 21a of the two first sliding grooves 21 along the second direction can be determined according to the size of the cutter arms 11 along the second direction, for example, when the two cutter arms 11 are located at the starting ends 21a, the back parts 11b of the two cutter arms 11 abut each other along the second direction.

[0050] The connecting part 11d is in sliding fit with the first sliding groove 21, when the connecting part 11d is located at the starting end 21a (i.e., located at the position shown by the dashed line in FIG. 6), the tip part 11c is located at the side close to the terminal end 21b, that is, the tip part 11c faces the terminal end 21b. Figure 2

[0051] The specific structure of the connecting part 11d is not limited, for example, the connecting part 11d is in the shape of a column, and at least part of the structure of the connecting part 11d is located in the first sliding groove 21, so that the connecting part 11d is in sliding fit with the first sliding groove 21.

[0052] ​In the embodiment, the tool 1 slides along the starting end 21a to the terminal end 21b, the tip part 11c will move in the first direction to pierce the target structure to form a breach, at the same time, the two blade parts 11a will move away from each other in the second direction, so as to expand the breach in the second direction to form a hole, and such movement mode helps to further improve the success rate of hole forming and improve the hole forming efficiency.

[0053] Of course, in some other embodiments, only one sliding groove can be provided, one tool arm 11 is in sliding cooperation with the sliding groove, and the other tool arm 11 is fixedly connected with the guide assembly 2.

[0054] In some other embodiments, all the groove sections of the first sliding groove 21 of the guide assembly 2 can extend in the second direction, that is, the first sliding groove 21 can only guide the movement of the tool arm 11 in the second direction, and in such embodiments, the tip part 11c can pierce the target structure by driving the guide assembly 2 and the tool 1 to move in the first direction as a whole by other power mechanisms.

[0055] In some embodiments, as mentioned above, the extension directions of at least a part of the groove sections of the two first sliding grooves 21 intersect.

[0056] Compared with the substantially zigzag-shaped first sliding groove 21 mentioned above, in such embodiments, the tip part 11c can move in the first direction while the two blade parts 11a move away from each other in the second direction, which improves the action efficiency of the tool 1 and further improves the hole forming efficiency. In addition, in such embodiments, the first power member 3 can only apply a force in the first direction to the tool 1, without applying a force in the second direction, so as to help simplify the structure of the first power member 3 and reduce the control difficulty.

[0057] In some embodiments, referring to Figure 3 , the tool arm 11 forms a hinged hole between the tip part 11c and the connecting part 11d, the hinged hole penetrates the tool arm 11 in the third direction, and the two tool arms 11 are stacked in the third direction. The tool 1 comprises a hinged shaft 12, the hinged shaft 12 is arranged in the hinged hole to hinge the two tool arms 11, and the first power member 3 comprises a linear module connected to the hinged shaft 12 and used to drive the hinged shaft 12 to move in the first direction.

[0058] The specific structure of the hinged shaft 12 is not limited, which can be arranged in the form of a scissors structure known to those skilled in the art, and will not be described here.

[0059] The first power member 3 comprises a linear module, such as a pneumatic cylinder, an oil cylinder, an electric cylinder, etc., which is not limited, and the output end of the linear module is connected to the hinged shaft 12, so as to push the hinged shaft 12 to move linearly in the first direction.

[0060] In the embodiment, the two cutter arms 11 of the cutter 1 are hingedly formed into a cross structure, so that the movements of the two cutter arms 11 of the cutter 1 will be synchronized and restricted to each other, which helps to improve the movement accuracy and stability of the cutter 1, and further helps to improve the accuracy and quality of the hole opening. Further, such a setting manner makes the first power member 3 only need to push the hinged shaft 12 to move linearly along the first direction through the linear module, without the need to respectively push the two cutter arms 11 to move, nor the need to push the cutter arms 11 to move in multiple directions, so as to be able to simplify the structure of the first power member 3, and further reduce the cost.

[0061] In some other embodiments, the two cutter arms 11 can also be completely independent, that is, the two cutter arms 11 are not connected to each other, and the first power member 3 can respectively drive the two cutter arms 11 to slide along the two first sliding grooves 21.

[0062] In some embodiments, referring to Figure 1 and Figure 2 , the guide assembly 2 includes a first guide plate 22, the first sliding groove 21 is formed in the first guide plate 22, the cutter 1 is arranged on one side of the first guide plate 22 along the third direction, the thickness direction of the first guide plate 22 is the third direction, the third direction is perpendicular to the first direction and the second direction, the starting end 21a and the terminal end 21b are distributed along the first direction, referring to Figure 2 , in the case where the connecting portion 11d is located at the starting end 21a (the position shown by the solid line in Figure 2 ), the cutting tip portion 11c is located within the first guide plate 22 along the first direction, and in the case where the connecting portion 11d is located at the terminal end 21b (the position shown by the dotted line in Figure 2 ), the cutting tip portion 11c exceeds the first guide plate 22 along the first direction.

[0063] As an example, the first sliding groove 21 can penetrate through the first guide plate 22 along the third direction.

[0064] In the embodiment, the first guide plate 22 can support the cutter 1 along the third direction, so as to improve the stability of the position of the cutter 1, and further, in the case where the cutter 1 is located at the starting end 21a, the cutting tip portion 11c is located within the first guide plate 22, so as to improve the use safety of the hole opening device, and reduce the possibility of accidental injury of the cutting tip portion 11c to the operator and other related personnel.

[0065] In some embodiments, referring to Figure 3 , the guide assembly 2 includes a second guide plate 23, the thickness direction of the second guide plate 23 is the third direction, the first guide plate 22 and the second guide plate 23 are respectively located on opposite sides of the cutter 1 along the third direction, the second guide plate 23 has a second sliding groove 24 extending along the first direction, and the hinged shaft 12 is in sliding fit with the second sliding groove 24 along the first direction.

[0066] As an example, the second sliding groove 24 extends through the second guide plate 23 along the third direction, the opening device further comprises a transmission block 7, the hinged shaft 12 is connected to the transmission block 7, the transmission block 7 is slidingly arranged in the second sliding groove 24, so as to realize the sliding fit of the hinged shaft 12 and the second sliding groove 24 along the first direction, and the first power member 3 is connected to the transmission block 7, so as to realize the connection with the hinged shaft 12.

[0067] In the embodiment, the second guide plate 23 is further arranged, the first guide plate 22 and the second guide plate 23 cooperatively form the installation space of the tool 1, so as to further improve the use safety of the opening device, and to provide protection for the tool 1 and improve the service life of the tool 1. Further, the second sliding groove 24 cooperating with the hinged shaft 12 is formed on the second guide plate 23, so that the reliability and smoothness of the movement of the tool 1 can be further improved, and the success rate and efficiency of the opening can be improved.

[0068] In some other embodiments, the guide assembly 2 can not include the second guide plate 23, and the second sliding groove 24 can be formed on the first guide plate 22.

[0069] In some embodiments, referring to Figure 1 and Figure 2 , the opening device comprises a base 4, and the guide assembly 2 is movably connected to the base 4.

[0070] Here, the specific structure of the base 4 is not limited, as long as it can support and fix the guide assembly 2, for example, the base 4 can be a frame structure, a box structure, a table structure, etc.

[0075] The specific structure of the second power member 6 is not limited here, as long as it can drive the guide assembly 2 to rotate about the rotation axis 5 relative to the base 4.
