Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting tools, in particular to a shearing jig. BACKGROUND

[0002] SMT (Surface Mounted Technology) is the most popular technology and process in the electronic industry. In the production process, the material belt needs to be sent into the automatic chip mounter for chip mounting. Since the length of each material belt is limited, when the old material belt is about to be used up, the new material belt is generally butt jointed with the old material belt by using the jointing belt to ensure the continuous work of the automatic chip mounter. Before the butt joint of the new material belt and the old material belt, the old material belt needs to be sheared to make the old material belt flush at the shearing position, so as to better butt joint with the new material belt and improve the precision of chip mounting.

[0003] However, scissors and similar tools are still used for shearing at present. When shearing material belts of different widths, such tools are not convenient for controlling the shearing precision of the material belt. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a shearing jig, which is beneficial to improve the shearing precision of material belts of different widths.

[0005] The embodiment of the present application provides a shearing jig for shearing a material belt. The shearing jig comprises a support, a shearing assembly and a bearing assembly. The shearing assembly comprises a tool holder and a first blade. The tool holder is rotationally connected with the support, and the first blade is arranged on the tool holder and rotates with the tool holder. The blade edge of the first blade protrudes from the tool holder towards the support. The bearing assembly comprises a bearing member. The bearing member is slidably arranged on the support along the direction of approaching or moving away from the tool holder. The bearing member is configured to bear the material belt.

[0006] When shearing material belts of different widths, the bearing member is slid a suitable distance along the direction of moving away from the tool holder to bear the material belts of different widths, and then the bearing member is slid along the direction of approaching the tool holder to a position where the first blade can shear the material belt, and then the tool holder is rotated to make the first blade shear the material belt. Therefore, by using the shearing jig, the shearing precision of material belts of different widths can be improved.

[0007] In some embodiments, the shearing jig comprises a limiting assembly connected with the support and the tool holder. The limiting assembly is configured to limit the rotation range of the tool holder relative to the support.

[0008] In the shearing jig of the above embodiment, the rotation range of the tool holder relative to the support is limited by the limiting assembly, which is beneficial to keep the blade edge of the first blade facing the support, thereby improving the safety when the bearing member is slid along the direction of approaching the tool holder to the shearing position of the first blade.

[0009] In some embodiments, the limiting component includes a limiting member and a limiting hole. One of the support member and the tool holder is provided with a limiting member, and the other of the support member and the tool holder is provided with a limiting hole. The limiting member moves in the limiting hole along the rotation direction of the tool holder.

[0010] In the shearing fixture of the above embodiment, the movement of the limiting member is restricted by the size of the limiting hole. By setting limiting holes of different sizes, it is convenient to adjust the rotation range of the tool holder relative to the support member.

[0011] In some embodiments, the shearing assembly includes a second blade disposed on the support. The cutting edge of the second blade is opposite to the cutting edge of the first blade.

[0012] In the shearing fixture of the above embodiment, the material strip is sheared by the cooperation of the first blade and the second blade, which makes the shearing process smoother and further improves the shearing accuracy of the material strip.

[0013] In some embodiments, the shearing fixture includes a sliding assembly, which includes a fixing member and a sliding member. The fixing member is disposed on the support member, and the sliding member is disposed on the load-bearing member. The sliding member and the fixing member are slidably connected.

[0014] In the shearing fixture of the above embodiments, the sliding engagement between the sliding member and the fixed member facilitates the convenient sliding of the bearing member relative to the support member.

[0015] In some embodiments, the support member has a second receiving portion, which includes a bottom wall, a first side wall, and a second side wall. The first and second side walls are connected to the bottom wall and are disposed opposite to each other. A fixing member is disposed on the bottom wall, and a sliding member slides between the first and second side walls. Along the sliding direction of the sliding member, the projection of the sliding member overlaps with the projections of the first and second side walls.

[0016] In the shearing fixture of the above embodiment, when the sliding member slides between the first sidewall and the second sidewall, it is beneficial to limit the sliding range of the sliding member by the first sidewall and the second sidewall, which helps to reduce the possibility of the sliding member separating from the fixed member, thereby helping to reduce the possibility of the load-bearing member separating from the support member.

[0017] In some embodiments, the carrier assembly includes at least two first positioning members, which are spaced apart from each other on the carrier assembly, and the line connecting the at least two first positioning members is perpendicular to the rotation plane of the cutter holder. The at least two first positioning members are configured to position the material strip.

[0018] In the shearing fixture of the above embodiment, the presence of at least two first positioning members helps to stably support the strip on the support member. When the shearing assembly shears the strip, it helps to reduce the possibility of strip deviation, thereby further improving the shearing accuracy of the strip.

[0019] In some embodiments, the carrier includes a first carrier portion and a second carrier portion spaced apart, and both the first carrier portion and the second carrier portion are provided with a first positioning element. Along the sliding direction of the carrier, a first blade is located between the first carrier portion and the second carrier portion.

[0020] In the shearing fixture of the above embodiment, by bearing the strip on the first bearing part and the second bearing part, and positioning the strip by the first positioning member provided on the first bearing part and the second bearing part, when shearing the strip, support can be formed on both sides of the shearing position of the strip. Compared with forming support only on one side of the shearing position of the strip, it is beneficial for the strip to remain stable during the shearing process, thereby making the cut of the strip more even.

[0021] In some embodiments, the carrier component includes at least four second positioning elements and at least two third positioning elements, which are spaced apart from each other on the carrier component. The line connecting the at least four second positioning elements is parallel to the line connecting the at least two third positioning elements. The at least four second positioning elements are configured to position two strips, and the at least two third positioning elements are configured to position the strips together.

[0022] In the shearing fixture of the above embodiment, when docking two strips, the connecting strip is first positioned by at least two third positioning members, and then the two strips are positioned by at least two second positioning members respectively. The two strips are placed on the connecting strip, and the docking of the two strips can be completed by applying pressure to the connecting strip and the two strips. This is beneficial for operators to complete the cutting and docking operations of the strips by using the shearing fixture, thereby improving the cutting efficiency of the strips.

[0023] In some embodiments, the shearing fixture includes a pressing member rotatably connected to the carrier in a direction close to or away from the second and third positioning members.

[0024] In the shearing fixture of the above embodiment, pressure can be easily applied to the connecting strip and the two strips by rotating the pressing member, thereby improving the convenience of connecting the two strips. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component.

[0032] Unless otherwise stated, the term "multiple" as used herein refers to two or more.

[0033] The terms “first”, “second”, etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implying the quantity, specific order, or primary and secondary relationship of the indicated technical features.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] This application discloses a shearing fixture for shearing strip material. The shearing fixture includes a support, a shearing assembly, and a carrier assembly. The shearing assembly includes a blade holder and a first blade. The blade holder is rotatably connected to the support, and the first blade is disposed on the blade holder and rotates with the blade holder. The cutting edge of the first blade protrudes from the blade holder towards the support. The carrier assembly includes a carrier member slidably disposed on the support in a direction approaching or away from the blade holder. The carrier member is configured to carry the strip material.

[0036] When cutting strips of different widths, the support member slides a suitable distance away from the cutter holder to support the strips of varying widths. Then, the support member slides closer to the cutter holder until it reaches a position where the first blade can cut. The cutter holder is then rotated to allow the first blade to cut the strip. This cutting fixture helps improve the cutting accuracy of strips of different widths.

[0037] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Please refer to the following: Figure 1 and Figure 3 The shearing fixture 10 includes a support member 11, a shearing assembly 12, and a load-bearing assembly 13. The shearing assembly 12 and the load-bearing assembly 13 are disposed on the support member 11.

[0039] The shearing assembly 12 includes a blade holder 121 and a first blade 122. The blade holder 121 is rotatably connected to the support member 11, and the first blade 122 is disposed on the blade holder 121 and rotates with the blade holder 121. The cutting edge of the first blade 122 protrudes from the blade holder 121 toward the support member 11.

[0040] The carrier assembly 13 includes a carrier 131, which is slidably disposed on the support 11 in a direction toward or away from the cutter holder 121. The carrier 131 is configured to carry the material strip 20.

[0041] When cutting strips 20 of different widths, the support member 131 is slid a suitable distance away from the cutter holder 121 to support the strips 20 of different widths. Then, the support member 131 is slid closer to the cutter holder 121 to a position where the first blade 122 can cut. Subsequently, the cutter holder 121 is rotated so that the first blade 122 cuts the strip 20. Thus, the cutting fixture 10 helps to improve the cutting accuracy of strips 20 of different widths.

[0042] In some embodiments, the tool holder 121 and the support member 11 are rotatably connected via a rotating shaft 101.

[0043] In some embodiments, the shearing assembly 12 includes a second blade 123 disposed on the support member 11. The cutting edge of the second blade 123 is opposite to the cutting edge of the first blade 122. By cooperating with the first blade 122 and the second blade 123 to shear the strip 20, the shearing process is smoother and the shearing accuracy of the strip 20 is further improved.

[0044] In some embodiments, the cutting edge of the second blade 123 does not protrude beyond the support member 11.

[0045] In some embodiments, the cutter holder 121 is provided with a handle 124, the extension direction of which is parallel to the rotation plane of the cutter holder 121. The handle 124 allows for convenient application of force to the cutter holder 121 to cut the strip 20.

[0046] In some embodiments, the support 11 includes a first receiving portion 111, and a second blade 123 is disposed in the first receiving portion 111. The first receiving portion 111 is recessed in the opposite direction of the third direction Z.

[0047] like Figure 2 As shown, the rotation plane of the tool holder 121 is perpendicular to the first direction X, the sliding direction of the support member 131 is parallel to the second direction Y, and the third direction Z is perpendicular to the first direction X and the second direction Y. In some embodiments, the support member 131 slides reciprocally along the second direction Y and the opposite direction of the second direction Y.

[0048] In some embodiments, the shearing fixture 10 includes a sliding assembly 14, which includes a fixing member 141 and a sliding member 142. The fixing member 141 is disposed on the support member 11, and the sliding member 142 is disposed on the carrier member 131. The sliding member 142 is slidably connected to the fixing member 141. The sliding engagement between the sliding member 142 and the fixing member 141 facilitates the convenient sliding of the carrier member 131 relative to the support member 11.

[0049] In some embodiments, please refer to Figure 3 The fixing member 141 is provided with a groove 1411 extending along the first direction X, and the sliding member 142 is provided with a slide rail 1421 extending along the first direction X. The slide rail 1421 is slidably disposed in the groove 1411. By providing the groove 1411 and the slide rail 1412, the stability of the sliding connection between the sliding member 142 and the fixing member 141 is improved, thereby improving the stability of the sliding of the bearing member 131 relative to the support member 11.

[0050] In some other embodiments, the positions of the slide groove 1411 and the slide rail 1421 can be interchanged, that is, the fixing member 141 is provided with the slide rail 1421, and the sliding member 142 is provided with the slide groove 1411.

[0051] In some embodiments, the support member 11 is provided with a second receiving portion 112. The second receiving portion 112 is recessed in the opposite direction of the third direction Z, and the sliding component 14 is disposed in the second receiving portion 112.

[0052] In some embodiments, the second receiving portion 112 includes a bottom wall 1121, a first side wall 1122, and a second side wall 1123. The first side wall 1122 and the second side wall 1123 are connected to the bottom wall 1121 and are disposed opposite to each other. A fixing member 141 is disposed on the bottom wall 1121, and a sliding member 142 slides between the first side wall 1122 and the second side wall 1123.

[0053] In some embodiments, along the sliding direction of the slider 142, the projection of the slider 142 overlaps with the projections of the first sidewall 1122 and the second sidewall 1123. When the slider 142 slides between the first sidewall 1122 and the second sidewall 1123, it is advantageous to limit the sliding range of the slider 142 by the first sidewall 1122 and the second sidewall 1123, which helps to reduce the possibility of the slider 142 disengaging from the fixing member 141, thereby helping to reduce the possibility of the bearing member 131 disengaging from the support member 11.

[0054] In some embodiments, the shearing fixture 10 includes a limiting component 15 connecting the support member 11 and the blade holder 121. The limiting component 15 is configured to limit the range of rotation of the blade holder 121 relative to the support member 11. Limiting the range of rotation of the blade holder 121 relative to the support member 11 by the limiting component 15 helps to keep the cutting edge of the first blade 122 facing the support member 11, thereby improving the safety when the carrier member 131 slides towards the shearing position of the first blade 122 in a direction close to the blade holder 121.

[0055] In some embodiments, the limiting component 15 includes a limiting member 151 and a limiting hole 152. One of the support member 11 and the tool holder 121 is provided with the limiting member 151, and the other of the support member 11 and the tool holder 121 is provided with the limiting hole 152. The limiting member 151 moves within the limiting hole 152 along the rotation direction of the tool holder 121. The movement of the limiting member 151 is limited by the size of the limiting hole 152. By providing limiting holes 152 of different sizes, it is convenient to adjust the rotation range of the tool holder 121 relative to the support member 11.

[0056] In some embodiments, the support member 11 is provided with a limiting member 151, and the tool holder 121 is provided with a limiting hole 152. In other embodiments, the tool holder 121 is provided with a limiting member 151, and the support member 11 is provided with a limiting hole 152.

[0057] In some embodiments, the support assembly 13 includes at least two first positioning members 132, which are spaced apart from each other on the support assembly 131. The line connecting the at least two first positioning members 132 is perpendicular to the rotation plane of the cutter holder 121. The at least two first positioning members 132 are configured to position the strip 20. The presence of at least two first positioning members 132 helps to stably support the strip 20 on the support assembly 131. When the shearing assembly 12 shears the strip 20, it helps to reduce the possibility of the strip 20 shifting, thereby further improving the shearing accuracy of the strip 20.

[0058] In some embodiments, the number of first positioning members 132 may be 2, 3, 4, 5 or more.

[0059] In some embodiments, the strip 20 has a plurality of first positioning holes 201, which correspond to the first positioning member 132. The first positioning holes 201 cooperate with the first positioning member 132 to position the strip 20. It should be understood that the size of the first positioning holes 201 is the same for strips 20 of different widths, so the first positioning member 132 can adapt to and position strips 20 of different widths.

[0060] In some embodiments, the carrier 131 includes a first carrier portion 1311 and a second carrier portion 1312, which are spaced apart.

[0061] Both the first support portion 1311 and the second support portion 1312 are provided with a first positioning member 132. Along the sliding direction of the support member 131, the first blade 122 is located between the first support portion 1311 and the second support portion 1312.

[0062] By placing the strip 20 on the first support portion 1311 and the second support portion 1312, and positioning the strip 20 by the first positioning member 132 provided on the first support portion 1311 and the second support portion 1312, when the strip 20 is cut, support can be formed on both sides of the cutting position of the strip 20. Compared with support only being formed on one side of the cutting position of the strip 20, it is beneficial for the strip 20 to remain stable during the cutting process, thereby making the cut of the strip 20 more even.

[0063] It is understandable that when the shearing assembly 12 includes the second blade 123, the second blade 123 is also located between the first support portion 1311 and the second support portion 1312 along the sliding direction of the support member 131.

[0064] In some embodiments, the carrier component 13 includes at least four second positioning elements 133 and at least two third positioning elements 134, which are respectively spaced apart from the carrier component 131. The line connecting the at least four second positioning elements 133 is parallel to the line connecting the at least two third positioning elements 134. The at least four second positioning elements 133 are configured to position two material strips 20, and the at least two third positioning elements 134 are configured to position the connecting strips 30.

[0065] When connecting two strips 20, the connecting strip 30 is first positioned by at least two third positioning elements 134, and then the two strips 20 are positioned by at least two second positioning elements 133 respectively. The two strips 20 are placed on the connecting strip 30. By applying pressure to the connecting strip 30 and the two strips 20, the connection of the two strips 20 can be completed. This is beneficial for the operator to complete the cutting and connection operations of the strips 20 by using the cutting fixture 10, thereby improving the cutting efficiency of the strips 20.

[0066] In some embodiments, the number of second positioning members 133 may be 4, 5, 6, 7 or more. In some embodiments, the number of third positioning members 134 may be 2, 3, 4, 5 or more.

[0067] In some embodiments, the two strips 20 are an old strip 20 and a new strip 20, respectively. The old strip 20 refers to the strip 20 that is about to be used up, and the new strip 20 refers to the unused strip 20. In some embodiments, before the old strip 20 and the new strip 20 are connected, the old strip 20 is first cut by the cutting fixture 10.

[0068] In some embodiments, the connecting strap 30 has a plurality of second positioning holes 301, which correspond to the third positioning member 134. The second positioning holes 301 and the third positioning member 134 cooperate to position the connecting strap 30.

[0069] In some embodiments, the shearing fixture 10 includes a pressing member 16, which is rotatably connected to the carrier 131 in a direction close to or away from the second positioning member 133 and the third positioning member 134. By rotating the pressing member 16, pressure can be easily applied to the connecting strip 30 and the two strips 20, thereby improving the ease of connecting the two strips 20.

[0070] In some embodiments, the pressing member 16 has a first receiving portion 161 and a second receiving portion 162. The first receiving portion 161 is configured to receive a second positioning member 133, and the second receiving portion 162 is configured to receive a third positioning member 134. When pressure is applied to the connecting strip 30 and the two material strips 20 by the pressing member 16, the first receiving portion 161 can receive the second positioning member 133, and the second receiving portion 162 can receive the third positioning member 134. This facilitates the pressing member 16 pressing more evenly onto the connecting strip 30 and the two material strips 20, thereby improving the effect of the connecting strip 30 engaging with the two material strips 20.

[0071] In some embodiments, the first receiving portion 161 and the second receiving portion 162 are formed as openings or notches on the press-fit member 16.

[0072] The process of using the shearing fixture 10 of this application to shear and butt the strip 20 is as follows:

[0073] The carrier 131 is slid a suitable distance away from the cutter holder 121 to carry strips 20 of different widths. The first positioning hole 201 of the strip 20 is engaged with the first positioning member 132 to position the strip 20 on the carrier 131. The carrier 131 is slid towards the cutter holder 121 to the position where the first blade 122 can cut. Then the cutter holder 121 is rotated so that the first blade 122 cuts the strip 20.

[0074] The connecting strip 30 is positioned by cooperating with the third positioning member 134 through the second positioning hole 301 of the connecting strip 30. The cut strip 20 is removed from the first positioning member 132 and positioned by cooperating with the second positioning member 133 through the first positioning hole 201 of the strip 20. Then, the new strip 20 is also positioned by different second positioning members 133. At this time, the ends of the cut strip 20 and the new strip 20 are connected and placed on the connecting strip 30. The pressing member 16 is rotated to apply pressure to the connecting strip 30 and the two strips 20, thus completing the docking of the two strips 20.

[0075] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the substantive scope of this application fall within the scope of this application.
