Description
Technical Field
[0001] This application belongs to the field of disassembly tool technology, and specifically relates to a disassembly mechanism. Background Technology
[0002] In the assembly process of electronic products, such as mobile phones, the spring contacts soldered inside the phone case may be damaged during assembly, rendering the phone case unusable. Removing the damaged spring contacts and installing new ones would allow the phone case to be reused. However, existing disassembly tools are insufficient for removing the spring contacts soldered to the phone case. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a disassembly mechanism that can disassemble workpieces attached to a product.
[0004] An embodiment of this application provides a disassembly mechanism, including a support rod and a moving rod. The support rod is used to press against a product. The moving rod includes an abutment portion, a connecting portion, and an operating portion connected in sequence. The connecting portion is rotatably connected to the support rod via a rotating shaft. The abutment portion and the operating portion are located on opposite sides of the rotating shaft. The extending direction of the operating portion is parallel to the extending direction of the abutment portion. The extending direction of the connecting portion forms an angle α with the extending direction of the operating portion, where 90° < α < 180°. The abutment portion is used to abut against a workpiece connected to the product.
[0005] When the above-described disassembly mechanism is applied to a product, the operating part applies downward force to the support rod, causing it to press more tightly against the product. The connecting part is rotatably connected to the support rod via a pivot, and the extension direction of the operating part is parallel to the extension direction of the abutment part. The operating part and the abutment part are located on the upper and lower sides of the support rod, respectively. Thus, when the operating part applies downward force to the support rod, the abutment part applies upward force to the workpiece to remove it from the product. When the above-described disassembly mechanism is applied to a mobile phone case and a spring clip (i.e., the product is a mobile phone case and the workpiece is a spring clip), pressing down the operating part causes the support rod to press against the opening of the mobile phone case, and the abutment part applies upward force to the spring clip until the spring clip connected to the mobile phone case is removed, allowing the mobile phone case to be reused.
[0006] In some embodiments, the disassembly mechanism further includes an elastic element that connects the support rod and the connecting portion, respectively.
[0007] In some embodiments, the connecting part and / or support rod are provided with a mounting structure, and the elastic element is fixedly connected to the mounting structure.
[0008] In some embodiments, the connecting portion has a mounting groove, and the support rod includes a first rod portion and a second rod portion connected to each other, the second rod portion passing through the mounting groove, and the dimension of the second rod portion along the first direction being smaller than that of the first rod portion.
[0009] In some embodiments, the extension direction of the first rod is parallel to the extension direction of the second rod, and the extension direction of the first rod is perpendicular to the first direction.
[0010] In some embodiments, the mounting groove is provided with a first stop surface and a second stop surface. When the support rod abuts against the first stop surface, the disassembly mechanism is in a first position, and when the support rod abuts against the second stop surface, the disassembly mechanism is in a second position. The elastic deformation of the elastic element is greater when the disassembly mechanism is in the first position than when the disassembly mechanism is in the second position.
[0011] In some embodiments, the second rod portion is provided with a protrusion located on the side of the mounting groove facing the abutment portion, and the protrusion is used to abut against the second stop surface when the disassembly mechanism is in the second position.
[0012] In some embodiments, the abutting portion includes two protrusions spaced apart along a first direction, the two protrusions being used to abut against the workpiece.
[0013] In some embodiments, the support rod is provided with pads for pressing against the product.
[0014] In some embodiments, the pad is connected to a connecting block, the connecting block including an extension post and a snap-fit post connected together, the extension post being fixedly connected to the pad and passing through the support rod, and the snap-fit post being larger in size than the extension post and snapping into the support rod.

[0022] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation
[0023] 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.
[0024] 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.
[0025] In the description of the embodiments of this application, the technical terms "first", "second", etc. are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.
[0026] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately parallel. The two components described as "parallel" do not have to be absolute straight lines or planes, but can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".
[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.
[0028] During mobile phone assembly, the spring contacts welded inside the phone case may be damaged, rendering the phone case unusable. Removing the damaged spring contacts and installing new ones would allow the phone case to be reused. However, existing disassembly tools are insufficient for removing the spring contacts welded to the phone case.
[0029] An embodiment of this application provides a disassembly mechanism, including a support rod and a moving rod. The support rod is used to press against a product. The moving rod includes an abutment portion, a connecting portion, and an operating portion connected in sequence. The connecting portion is rotatably connected to the support rod via a rotating shaft. The abutment portion and the operating portion are located on opposite sides of the rotating shaft. The extending direction of the operating portion is parallel to the extending direction of the abutment portion. The extending direction of the connecting portion forms an angle α with the extending direction of the operating portion, where 90° < α < 180°. The abutment portion is used to abut against a workpiece connected to the product.
[0030] When the above-described disassembly mechanism is applied to a product, the operating part applies downward force to the support rod, causing it to press more tightly against the product. The connecting part is rotatably connected to the support rod via a pivot, and the extension direction of the operating part is parallel to the extension direction of the abutment part. The operating part and the abutment part are located on the upper and lower sides of the support rod, respectively. Thus, when the operating part applies downward force to the support rod, the abutment part applies upward force to the workpiece to remove it from the product. When the above-described disassembly mechanism is applied to a mobile phone case and a spring clip (i.e., the product is a mobile phone case and the workpiece is a spring clip), pressing down the operating part causes the support rod to press against the opening of the mobile phone case, and the abutment part applies upward force to the spring clip until the spring clip connected to the mobile phone case is removed, allowing the mobile phone case to be reused.
[0031] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0032] Please see Figure 1 This application provides a disassembly mechanism 100 in its embodiments. Please refer to... Figure 4 The disassembly mechanism 100 is used to disassemble the workpiece 300 connected to the product 200.
[0033] Please see Figure 5 Product 200 includes a base plate 210 and a side plate 220 connected together. The side plate 220 forms an opening 2001 on the side away from the base plate 210, and the inner wall of the side plate 220 is a side wall 2201. Workpiece 300 includes a welded part 310 and an extension part 320 connected together. The welded part 310 is welded to the side wall 2201 of product 200, and the extension part 320 is perpendicular to the welded part 310 and extends away from the welded side wall 2201.
[0034] In some embodiments, product 200 is a mobile phone case. Workpiece 300 is a spring clip.
[0035] Please see Figure 1 and Figure 2In some embodiments, the disassembly mechanism 100 includes a support rod 10 and a moving rod 20. The support rod 10 is used to press against the opening 2001 of the product 200. The moving rod 20 is rotatably connected to the support rod 10 and is used to pry off the workpiece 300 attached to the product 200.
[0036] The moving rod 20 includes an abutment portion 21, a connecting portion 22, and an operating portion 23 connected in sequence. The connecting portion 22 is rotatably connected to the support rod 10 via a rotating shaft 30, so that the moving rod 20 and the support rod 10 are rotatably connected via the rotating shaft 30. The abutment portion 21 and the operating portion 23 are located on the upper and lower sides of the support rod 10, respectively, and also on the left and right sides of the rotating shaft 30. The extending direction of the operating portion 23 is parallel to the extending direction of the abutment portion 21, and the abutment portion 21 and the operating portion 23 have the same degree of inclination. The extending direction of the connecting portion 22 and the extending direction of the operating portion 23 form an angle α, where 90° < α < 180°. The abutment portion 21 abuts against the side of the workpiece 300 facing away from the opening 2001. The operating portion 23 applies force to the support rod 10 towards the opening 2001.
[0037] In use, the product 200 is placed horizontally on the operating table, and the support rod 10 is placed horizontally at the opening 2001 of the product 200. Without external force acting on the operating part 23, the operating part 23, the abutment part 21, and the support rod 10 are all horizontally positioned, while the connecting part 22 is inclined. At this time, the abutment part 21 and the operating part 23 can be respectively located on the upper and lower sides of the support rod 10. When a downward force is applied to the operating part 23, the support rod 10 presses more tightly against the opening 2001 of the side plate 220 of the product 200, and the abutment part 21 applies an upward force to the workpiece 300. The greater the force applied to the operating part 23 towards the support rod 10, the tighter the connection between the support rod 10 and the product 200, and the greater the force applied by the abutment part 21 to the workpiece 300, until the workpiece 300 connected to the product 200 is detached.
[0038] In some embodiments, the included angle α is 130°, which is applicable to the workpiece 300 in this application. When the support rod 10 is placed horizontally on the product 200, the larger the included angle α, the closer the distance between the abutment part 21 and the workpiece 300, and the thinner workpiece 300 can be disassembled. When the included angle α is smaller, the farther the distance between the abutment part 21 and the workpiece 300, and the thicker workpiece 300 can be disassembled.
[0039] In some embodiments, both the connecting part 22 and the support rod 10 are provided with a connecting hole 225 through which the support rod 10 passes, and the rotating shaft 30 passes through the connecting hole 225, so that the support rod 10 and the moving rod 20 can be rotatably connected through the rotating shaft 30.
[0040] In the illustrated embodiment, one end of the rotating shaft 30 is larger than the connecting hole 225, and a retaining ring 31 is provided at one end of the rotating shaft 30 to prevent the rotating shaft 30 from falling out of the connecting part 22, so that the connection between the connecting part 22 and the support rod 10 is more stable.
[0041] In some embodiments, the pivot 30 is connected to the end of the support rod 10 facing the abutment portion 21, that is, the pivot 30 is positioned closer to the abutment portion 21. According to the lever principle, the pivot 30 is the fulcrum between the moving rod 20 and the support rod 10. When the power arm is longer, only a smaller force is needed to move a heavier object. That is, when the operating part 23 is farther away from the pivot 30, the force required to pry off the workpiece 300 is smaller, thereby saving the force required to pry off the workpiece 300.
[0042] In some embodiments, the support rod 10 includes a first rod portion 11 and a second rod portion 12 connected to each other. The extending direction of the first rod portion 11 is parallel to the extending direction of the second rod portion 12, making the support rod 10 elongated. Thus, when the support rod 10 is placed horizontally on the product 200, both ends of the bottom surface of the support rod 10 overlap the side plate 220 of the product 200. At this time, the moving rod 20 uses the support rod 10 as a fulcrum, and the support rod 10 uses the product 200 as a fulcrum, so the disassembly mechanism 100 uses the product 200 as a support point to pry off the workpiece 300 connected to the product 200, which is highly convenient to operate. The extending direction of the first rod portion 11 is perpendicular to the first direction X.
[0043] Please see Figure 1 and Figure 2 In some embodiments, the abutment portion 21 includes two protrusions 211 spaced apart along a first direction X. The two protrusions 211 are used to abut against the two extensions 320 of the workpiece 300 (see figure). Figure 5 The two protrusions 211 can adapt to the extension 320 of the workpiece 300, so that the shape of the abutment 21 adapts to the shape of the workpiece 300, so that the abutment 21 can apply force to the workpiece 300 toward the opening 2001.
[0044] Please see Figures 1 to 3 In some embodiments, the disassembly mechanism 100 further includes an elastic element 40. The elastic element 40 is located on the side of the rotating shaft 30 facing the operating part 23, and is connected to both the support rod 10 and the connecting part 22, allowing the abutment part 21 to elastically move towards the support rod 10. When the operating part 23 moves towards the support rod 10, the elastic element 40 elastically compresses. The elastic element 40 rebounds, causing the operating part 23 to move away from the support rod 10, thus elastically returning the operating part 23 and the abutment part 21 to their original positions.
[0045] In some embodiments, the elastic element 40 is a spring.
[0046] In some embodiments, the connecting portion 22 and / or the support rod 10 are provided with a mounting structure 2241. The elastic element 40 is fixedly connected to the mounting structure 2241.
[0047] Please see Figure 3 In the illustrated embodiment, the mounting structure 2241 is a mounting hole. Both the connecting part 22 and the support rod 10 are provided with mounting holes. Both ends of the elastic member 40 are located in the mounting holes to protect and guide the direction of elastic deformation of the elastic member 40, so that the connection between the elastic member 40 and the connecting part 22 and the support rod 10 is more stable and less likely to be damaged or shaken during elastic deformation.
[0048] In some embodiments, the mounting structure 2241 may be a protruding post. The elastic element 40 is fixedly sleeved on the protruding post, so that the protruding post can guide the direction of elastic deformation of the elastic element 40.
[0049] In some embodiments, a stop 224 is fixedly provided at one end of the operating part 23 of the connecting part 22, and a mounting structure 2241 is provided on the stop 224. The side of the stop 224 facing the operating part 23 and the side of the stop 224 facing the support rod 10 form an L-shape. When the elastic member 40 is elastically compressed to its shortest length, the stop 224 abuts against the support rod 10, thereby limiting the distance that the operating part 23 can move toward the support rod 10, so as to prevent the elastic member 40 from being damaged due to excessive movement of the operating part 23 toward the support rod 10.
[0050] Please see Figure 2 In some embodiments, the connecting portion 22 has a mounting groove 221, through which the second rod portion 12 passes. Along the first direction X, i.e., the width direction of the connecting portion 22: the size of the second rod portion 12 is smaller than that of the first rod portion 11, so that the second rod portion 12 passes through the mounting groove 221. The first rod portion 11 and the second rod portion 12 are located on the left and right sides of the mounting groove 221, respectively. The mounting groove 221 is located at the center of the connecting portion 22 along the first direction X, making the connection between the support rod 10 and the connecting portion 22 more stable. The rotated support rod 10 and moving rod 20 are less likely to wobble in the first direction X. The abutment portion 21 applies a more uniform thrust, preventing different thrusts on the two extension portions 320.
[0051] Please see Figure 2 In some embodiments, the first rod portion 11 has an inclined surface 111 facing the second rod portion 12. When the operating portion 23 is in an unloaded state, the inclined surface 111 serves to abut against the connecting portion 22 to limit the connecting portion 22 from driving the operating portion 23 to rotate toward the support rod 10 when unloaded.
[0052] Please see Figure 2 and Figure 3In some embodiments, the mounting groove 221 is provided with a first stop surface 222 and a second stop surface 223. When the support rod 10 abuts against the first stop surface 222, the disassembly mechanism 100 is in a first position. At this time, the abutment part 21 cannot continue to move toward the support rod 10, thereby controlling the closest distance between the abutment part 21 and the support rod 10 and preventing the abutment part 21 from hitting the support rod 10 without applying force to the workpiece 300, which would cause damage to the disassembly mechanism 100.
[0053] When the support rod 10 abuts against the second stop surface 223, the disassembly mechanism 100 is in the second position. At this time, the operating part 23 can no longer move away from the support rod 10, thereby controlling the farthest distance between the operating part 23 and the support rod 10, preventing the operating part 23 from moving excessively away from the support rod 10, thereby limiting the limit of the elastic member 40's elastic return.
[0054] The elastic deformation of the elastic element 40 is greater when the disassembly mechanism 100 is in the first position than when it is in the second position. When the disassembly mechanism 100 is in the first position, the elastic element 40 is elastically compressed and is in its shortest state. When the disassembly mechanism 100 is in the second position, the elastic element 40 elastically returns to its original length.
[0055] In some embodiments, the second rod portion 12 is provided with a protrusion 13, which can pass through the mounting groove 221 together with the second rod portion 12, that is, the protrusion 13 is located on the side of the mounting groove 221 facing the abutment portion 21. The protrusion 13 is used to abut against the second stop surface 223 when the disassembly mechanism 100 is in the second position.
[0056] Please see Figure 3 In some embodiments, two pads 14 are connected to the support rod 10. One pad 14 is connected to the first rod portion 11, and the other pad 14 is connected to the second rod portion 12. The two pads 14 are used to press against the side plate 220 of the product 200 when the support rod 10 is placed on the product 200, thereby preventing the support rod 10 from damaging the product 200. The pads 14 are made of flexible material to protect the product 200.
[0057] In some embodiments, the pad 14 is fixedly connected to a connecting block 15. The connecting block 15 includes an extension post 151 and a snap-fit post 152 connected to each other. The extension post 151 is fixedly connected to the side of the pad 14 facing the support rod 10. The extension post 151 passes through the support rod 10. The snap-fit post 152 is larger than the extension post 151. After the extension post 151 passes through the support rod 10, the snap-fit post 152 snaps into the support rod 10, thereby snapping the connecting block 15 into the support rod 10.
[0058] In some embodiments, the support rod 10 has a through hole and a receiving groove, the extension post 151 passes through the through hole, and the snap-fit post 152 is located in the receiving groove. The connecting block 15 is made of flexible material, allowing the snap-fit post 152 to pass through the through hole and snap into the receiving groove under external force, thus connecting the connecting block 15 and the pad 14 to the support rod 10. When the pad 14 is pulled downwards, the pad 14 and the connecting block 15 can be disassembled to replace the new pad 14.
[0059] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of disclosure of this application.
