Description

Technical Field

[0001] This application relates to the field of processing technology, and in particular to a lifting device. Background Technology

[0002] In the assembly process of electronic devices, for certain special-shaped, ultra-thin and fragile or easily scratched components (such as micro sensors, flexible circuits, ceramic capacitors, etc.), directly picking and placing them manually or using tweezers is not only inefficient, but also carries the risk of damage due to uneven force control or improper contact. Utility Model Content

[0003] In view of the above situation, this application provides a lifting device to solve the above problems.

[0004] This application provides a lifting device for lifting a workpiece. The lifting device includes a base and a lifting mechanism. The base includes a first surface and a second surface disposed opposite each other along a first direction, with the first surface configured to support the workpiece. The base has a first through hole extending through the first and second surfaces along the first direction. The lifting mechanism includes a base, a linkage block, a ejector pin, and a handle. The base is disposed on one side of the second surface, the linkage block is movably disposed between the base and the second surface along the first direction, and the ejector pin is fixed to the linkage block and configured to pass through the first through hole. The handle includes a rotating shaft and an input force arm and an output force arm disposed on both sides of the rotating shaft. The rotating shaft is rotatably connected to the base, the output force arm abuts against the linkage block, and the input force arm protrudes outward from the base.

[0005] In the aforementioned lifting device, a material-bearing component is mounted on the first surface, and a first through hole is provided on the base, extending through both the first and second surfaces in a first direction. A rotating shaft is rotatably connected to the base, and an input force arm abuts against a linkage block, with the input force arm protruding outward from the base. In use, pressing the portion of the input force arm protruding from the base drives the handle to rotate around the rotating shaft, lifting the input force arm and subsequently pushing the linkage block towards the second surface. This allows the ejector pin to pass through the first through hole, lifting the material on the first surface, facilitating component removal, improving efficiency, and reducing the risk of component damage.

[0006] In some embodiments of this application, the lifting device includes a positioning member extending from a first surface in a first direction away from the base, and the material has a positioning hole. The positioning member is configured to pass through the positioning hole to define the position of the material on the first surface.

[0007] In some embodiments of this application, the lifting device includes a guide rod extending from the base to the pedestal in a first direction. The linkage block is provided with a guide hole extending in the first direction, through which the guide rod passes to improve the stability of the linkage block moving in the first direction.

[0008] In some embodiments of this application, the lifting device includes a spring sleeved on a guide rod, which elastically holds the linkage block against the base in a first direction. When the pressing is finished and the input arm is released, the linkage block sinks under the action of gravity and elastic force, thereby driving the input arm back to the initial position, thus completing the reset for the next operation.

[0009] In some embodiments of this application, the guide rod includes an extension and a limiting portion fixed along a first direction. A connecting portion is connected between the base and the limiting portion. When viewed along the first direction, the size of the limiting portion is larger than the size of the extension. A spring is sleeved on the extension, and both ends of the spring abut against the limiting portion and the linkage block, respectively, to improve the positional stability of the spring.

[0010] In some embodiments of this application, the linkage block includes a first support surface facing the base in a first direction. The first support surface is provided with a first recess, at least a portion of the output lever is located in the first recess, and the output lever abuts against the bottom surface of the first recess facing the base, so as to reduce the risk of poor contact caused by the output lever deviating from the linkage block, and to improve the integration of the lifting mechanism.

[0011] In some embodiments of this application, the base includes a second support surface facing the linkage block along a first direction. The second support surface is provided with a first protrusion, and the first protrusion is provided with a shaft hole. The axis of the shaft hole is perpendicular to the first direction, and the rotating shaft passes through the shaft hole to improve the stability of the handle rotating around the shaft.

[0012] In some embodiments of this application, the output lever arm includes two sub-lever arms spaced apart along the axial direction of the shaft, a first protrusion located between the two sub-lever arms, and the two sub-lever arms respectively abutting against the linkage block, so that the force applied by the output lever arm can be transmitted to the linkage block in a balanced manner.

[0013] In some embodiments of this application, the second support surface is provided with a clearance groove, and the projection of the input lever arm overlaps with the projection of the clearance groove along the first direction. When the input lever arm is pressed, it can fall into the clearance groove, thereby providing a larger stroke space for the lifting action of the output lever arm.

[0014] In some embodiments of this application, the lifting device includes a fixed plate and a bracket, with the base fixed to the fixed plate and the bracket located on one side of the base and fixed between the base and the fixed plate along a first direction, so as to improve the overall structural stability of the lifting device.

Detailed Implementation

[0020] 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.

[0021] 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 there may be components positioned in between. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be components positioned in between. It should be understood that, considering the factors of actual machining tolerances, in the technical solution of this application, when two components are set parallel / perpendicularly, they are set in the same direction, and there may be a certain angle between the two components. The angle between the two components is allowed to have a tolerance of 0-±10%. When a value is considered to be "equal" to another value, it means that the two are equal within a set deviation range, which is within 10%. That is to say, when at least one of the two values ​​fluctuates within the set deviation range, even if their values ​​are not equal, they are still judged to be approximately equal.

[0022] 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. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0024] Please refer to the following: Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a lifting device 100 for lifting a material 90. The lifting device 100 includes a base 10 and a lifting mechanism 20.

[0025] The base 10 includes a first surface 11 and a second surface 12 disposed opposite each other along a first direction Z. The first surface 11 is configured to support a material 90. The base 10 has a first through hole 13 extending through the first surface 11 and the second surface 12 along the first direction Z. Specifically, at least a portion of one surface of the material 90 is in contact with the first surface 11, and the material 90 covers the first through hole 13.

[0026] The lifting mechanism 20 includes a base 21, a linkage block 22, a ejector pin 23, and a handle 24. The base 21 is disposed on one side of the second surface 12, and the linkage block 22 is movably disposed between the base 21 and the second surface 12 along a first direction Z. The ejector pin 23 is fixed to the linkage block 22 and configured to pass through a first through hole 13. The linkage block 22 drives the ejector pin 23 to move along the first direction Z. When the ejector pin 23 protrudes from the first surface 11, it can lift the material 90 carried on the first surface 11.

[0027] The handle 24 includes a rotating shaft 241 and input force arms 242 and output force arms 243 disposed on both sides of the rotating shaft 241. The rotating shaft 241 is rotatably connected to the base 21, so that the handle 24 can rotate around the rotating shaft 241 to form a lever structure. The input force arm 242 abuts against the linkage block 22 and protrudes outward from the base 10. In use, pressing the part of the input force arm 242 protruding from the base 10 drives the handle 24 to rotate around the rotating shaft 241, causing the input force arm 242 to rise, thereby pushing the linkage block 22 to move along the first direction Z toward the second surface 12, so that the ejector pin 23 passes through the first through hole 13, lifting the material 90 on the first surface 11, which facilitates the removal of the part, improves efficiency, and reduces the risk of damage to the material 90.

[0028] Furthermore, when the input lever 242 is released after pressing, the linkage block 22 will sink under the action of gravity, which will then drive the input lever 242 back to the initial position, thereby completing the reset so that the next operation can be performed.

[0029] Please refer to the following: Figure 2 and Figure 4 In some embodiments, there are multiple first through holes 13, and each first through hole 13 corresponds to a ejector pin 23, so that the force applied by the ejector pin 23 can be transmitted to the workpiece 90 in a balanced manner.

[0030] Optionally, the number of first through holes 13 is 2, 3, 4, or any other value greater than or equal to 2.

[0031] Please refer to the following: Figure 2 and Figure 4 In some embodiments, the lifting device 100 includes a positioning member 30 extending from the first surface 11 in a first direction Z toward the base 10. The material 90 is provided with a positioning hole 91, and the positioning member 30 is configured to pass through the positioning hole 91 to define the position of the material 90 on the first surface 11.

[0032] In some embodiments, the positioning element 30 includes a positioning pin.

[0033] It is understood that in some embodiments, the first surface 11 is provided with a positioning recess for holding the protruding part of the material 90 itself, so as to limit the position of the material 90 on the first surface 11.

[0034] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the lifting device 100 includes a guide rod 40 that extends from the base 21 toward the base 10 in a first direction Z. The linkage block 22 is provided with a guide hole 221 extending in the first direction Z. The guide rod 40 passes through the guide hole 221 to improve the stability of the linkage block 22 moving in the first direction Z.

[0035] In some embodiments, there are multiple guide rods 40, and each guide rod 40 corresponds to a guide hole 221 to further improve the stability of the linkage block 22 moving along the first direction Z.

[0036] Optionally, the number of guide rods 40 is 2, 3, 4, or any other value greater than or equal to 2.

[0037] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the lifting device 100 includes a spring 50, which is sleeved on the guide rod 40. The spring 50 elastically holds the linkage block 22 against the base 21 along the first direction Z. When the pressing ends and the input force arm 242 is released, the linkage block 22 will sink under the action of gravity and elastic force, thereby driving the input force arm 242 back to the initial position, thus completing the reset for the next operation.

[0038] Please see Figure 4 In some embodiments, the guide rod 40 includes an extension 41 and a limiting portion 42 fixed along a first direction Z. The extension 41 is connected between the base 21 and the limiting portion 42. Viewed along the first direction Z, the size of the limiting portion 42 is larger than the size of the extension 41. A spring 50 is sleeved on the extension 41, and both ends of the spring 50 abut against the limiting portion 42 and the linkage block 22, respectively, to improve the positional stability of the spring 50.

[0039] In some embodiments, the guide hole 221 has a bushing 222 on its wall, and the end of the spring 50 away from the limiting part 42 abuts against the bushing 222. The bushing 222 is used to reduce the friction and wear of the linkage block 22.

[0040] Please refer to the following: Figure 3 and Figure 4In some embodiments, the linkage block 22 includes a first support surface 223 facing the base 21 along a first direction Z. The first support surface 223 is provided with a first recess 2231, at least a portion of the output lever arm 243 is located in the first recess 2231, and the output lever arm 243 abuts against the bottom surface of the first recess 2231 facing the base 21, so as to reduce the risk of poor contact caused by the output lever arm 243 deviating from the linkage block 22, and to improve the integration of the lifting mechanism 20.

[0041] Please refer to the following: Figure 2 and Figure 4 In some embodiments, the base 21 includes a second support surface 211 facing the linkage block 22 along a first direction Z. The second support surface 211 has a first protrusion 2111, and the first protrusion 2111 has a shaft hole 2112, the axis of which is perpendicular to the first direction Z. The rotating shaft 241 passes through the shaft hole 2112 to improve the stability of the handle 24 rotating about the rotating shaft 241.

[0042] Please refer to the following: Figure 2 and Figure 4 In some embodiments, the output lever arm 243 includes two sub-lever arms 2431 spaced apart along the axial direction of the shaft 241. A first protrusion 2111 is located between the two sub-lever arms 2431, and the two sub-lever arms 2431 respectively abut against the linkage block 22 so that the force applied by the output lever arm 243 can be transmitted to the linkage block 22 in a balanced manner.

[0043] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the second support surface 211 is provided with a relief groove 2113, and the projection of the input arm 242 overlaps with the projection of the relief groove 2113 along the first direction Z. When the input arm 242 is pressed, it can fall into the relief groove 2113, so as to provide a larger stroke space for the lifting action of the output arm 243.

[0044] In some embodiments, the length of the input lever arm 242 is greater than that of the output lever arm 243 along the length direction of the handle 24. According to the lever principle, this is a force-saving lever structure, requiring a smaller input force while having a larger output force, thus achieving efficient force transmission.

[0045] In some embodiments, the length of the input lever arm 242 is less than that of the output lever arm 243 along the length direction of the handle 24. In this case, the handle 24 constitutes a speed-increasing lever mechanism with displacement amplification function. A small displacement at the input end can generate a larger stroke at the output end, enabling rapid lifting.

[0046] Please refer to the following: Figure 2 and Figure 4In some embodiments, the end of the input lever 242 away from the pivot 241 is provided with a first convex surface 2421, which fits the finger and makes it easy for the user to press the input lever 242 comfortably and effortlessly.

[0047] In some embodiments, the end of the output lever arm 243 away from the rotating shaft 241 is provided with a second convex surface 2432, which abuts against the linkage block 22 to form a low-friction contact, reduce operating resistance and improve force transmission efficiency.

[0048] Please refer to the following: Figure 1 and Figure 4 In some embodiments, the lifting device 100 includes a fixed plate 60 and a bracket 70. The base 21 is fixed to the fixed plate 60, and the bracket 70 is located on one side of the base 21 and fixed between the base 10 and the fixed plate 60 along the first direction Z, so as to improve the overall structural stability of the lifting device 100.

[0049] In some embodiments, the base 10 and the support 70 are integrally formed to improve the overall structural stability of the lifting device 100.

[0050] In some embodiments, the fixing plate 60 is provided with fixing holes 61, which are configured to be fixed to an external structure.

[0051] In the aforementioned lifting device 100, a first surface 11 is configured to support a material 90, and a base 10 has a first through hole 13 extending along the first direction Z through the first surface 11 and the second surface 12. A rotating shaft 241 is rotatably connected to a base 21, and an input force arm 242 abuts against a linkage block 22, with the input force arm 242 protruding outward from the base 10. In use, pressing the portion of the input force arm 242 protruding from the base 10 drives the handle 24 to rotate around the rotating shaft 241, lifting the input force arm 242, which in turn pushes the linkage block 22 to move along the first direction Z toward the second surface 12, causing the ejector pin 23 to pass through the first through hole 13 and lift the material 90 on the first surface 11, facilitating material removal, improving efficiency, and reducing the risk of damage to the material 90.

[0052] In addition, those skilled in the art may make other changes within the spirit of this application. Of course, all such changes made in accordance with the spirit of this application should be included within the scope disclosed in this application.
