Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a clamping mechanism and an automatic feeding device. Background Art

[0002] During the chip packaging process, the package surface is sputtered to protect the product. Typically, one side of the chip connects to external circuitry and cannot be covered with sputtered metal. Therefore, the chip is attached to the tape on the square ring and subjected to a pressure-maintaining process to ensure a tight fit between the chip and the tape, preventing air bubbles from forming between them.

[0003] In the related art, the square ring has a large hole in the middle, and the ring plate of the square ring is small in width and thin in thickness. Workers need to remove the square ring from the material frame and place it into the pressure-holding equipment, resulting in low production efficiency and high labor costs. Although suction cup manipulators and other loading and unloading structures are used in the chip production process, if a suction cup manipulator is used to shift and transport the square ring, the small width of the ring edge of the square ring makes it difficult to provide sufficient fulcrums for the suction cups. Insufficient adsorption force can easily cause the square ring to fall or become misplaced. In addition, the suction cups need to exert a large force to suck up the entire square ring before shifting it, making it difficult to ensure the positional accuracy of the square ring during the shifting process.

[0078] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0079] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0080] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0081] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0082] like Figures 1 to 3 As shown, the Z direction shown in the figure is a schematic diagram of the first direction, the X direction shown in the figure is a schematic diagram of the second direction, and the Y direction shown in the figure is a schematic diagram of the third direction. The embodiment of the first aspect of the present utility model provides a clamping mechanism for clamping a to-be-clamped part 5. Specifically, the clamping mechanism includes a lifting module 1, a transfer module 2, and a clamping module 3. The lifting module 1 includes a lifting platform 11 and a lifting drive member 12 that are connected to each other in a transmission manner. The lifting drive member 12 is configured to drive the lifting platform 11 to lift and lower in a first direction. A plurality of to-be-clamped parts 5 can be placed at intervals in the first direction. The lifting module 1 is configured to drive the clamping module 3 to clamp different to-be-clamped parts 5.

[0083] The transfer module 2 includes a transfer drive 21 and a transfer bracket 22 that are transmission-connected to each other. The transfer bracket 22 can be slidably set on the lifting platform 11. The transfer drive 21 is configured to drive the transfer bracket 22 to move in the second direction. The first direction intersects with the second direction, that is, the first direction and the second direction are different directions with an angle. For example, the first direction can be a vertical direction, and the second direction can be a horizontal direction. The first direction and the second direction are perpendicular to each other. Of course, the first direction can also be preset with a vertical offset angle between the vertical direction, and the second direction can also be preset with a horizontal offset angle between the horizontal direction. The first direction and the second direction can also be in a non-vertical state.

[0084] The clamping module 3 is arranged on the transfer bracket 22. The clamping module 3 includes a positioning member 31 and a plurality of clamping members 32. The positioning member 31 and the plurality of clamping members 32 can be arranged on the transfer bracket 22 and move together with the transfer bracket 22. The plurality of clamping members 32 are arranged on both sides of the positioning member 31. The positioning member 31 is configured to be abutted and positioned by the part to be clamped 5. The clamping member 32 is configured to clamp the part to be clamped 5. The positioning member 31 is configured to locate the clamping position of the clamping member 32 on the part to be clamped 5. The plurality of clamping members 32 are arranged at intervals on both sides of the positioning member 31 and are configured to form a plurality of clamping points. For example, the plurality of clamping members 32 and the positioning member 31 can be arranged at intervals along a third direction, and the third direction intersects with the first direction and the second direction in pairs. Optionally, the third direction is perpendicular to the first direction and the second direction in pairs.

[0085] With this arrangement, when it is necessary to clamp an object 5 at a certain position, the lifting drive 12 drives the lifting platform 11 to move up and down in the first direction, thereby driving the transfer module 2 and the clamping module 3 to move up and down together, so as to adjust the clamping member 32 to align with the object 5 in the first direction. The transfer drive 21 drives the transfer bracket 22 to move closer to the placement position of the object 5 until the edge of the object 5 abuts the positioning member 31 to initially position the object 5, ensuring the accuracy of the clamping position of the object 5 by the clamping member 32.

[0086] The clamping member 32 is configured to clamp and secure the object 5 to be clamped. The mobile drive member drives the mobile bracket to move in the second direction away from the placement position of the object 5 to be clamped, thereby removing the object 5 from the placement position. The lifting drive member 12 is also configured to adjust the clamping module 3 and the object 5 to be clamped as a whole to various conveying heights by driving the lifting platform 11 to rise and fall in the first direction. This facilitates the re-export of the object 5 to be clamped to different locations, avoiding manual pick-and-place operations, reducing labor intensity, improving production efficiency, and reducing manual errors. Multiple objects 5 to be clamped are loaded sequentially, avoiding the mixing of work orders.

[0087] The positioning member 31 is configured to position the clamping member 32 relative to the clamped member 5, so that the clamping member 32 can accurately clamp and transport the clamped member 5, reducing transport errors. Multiple clamping members 32 are spaced apart on both sides of the positioning member 31 and are configured to form multiple clamping points. Multiple clamping members 32 are configured to be dispersed at the edge of the clamped member 5, suitable for clamping materials such as square rings. The clamping module 3 applies force to the clamped member 5 evenly and stably, reducing the relative displacement between the clamping module 3 and the clamped member 5. This solves the problems in the related art of requiring manual pick-up and placement, which is labor-intensive and has low production efficiency, as well as the difficulty of the loading and unloading structure in adapting to the displacement and transport of square rings, resulting in low precision in the displacement position of square rings.

[0088] In this embodiment, the object 5 to be clamped can be, but is not limited to, an annular sheet structure such as a square ring, or a non-annular sheet structure. For example, the non-annular sheet structure can be a circular sheet or a square sheet. The overall outer contour of the object 5 to be clamped can be, but is not limited to, a polygonal shape such as a square or rectangle, or a circle, and is configured to be clamped by the clamping module 3. The object 5 to be clamped can serve as a carrier. One side of the object 5 to be clamped is affixed with an adhesive layer such as tape for attaching products such as chips and performing a sputtering process.

[0089] like Figures 1 to 3 As shown, in some embodiments, the piece to be clamped 5 is an annular sheet structure, and the clamping mechanism further includes a conveying module 4, which includes at least two conveyor belt structures 41 and a conveying drive member 42. The conveyor belt structure 41 is arranged on the lifting platform 11, and the at least two conveyor belt structures 41 are respectively arranged on both sides of the clamping module 3. The conveying drive member 42 is transmission-connected with the conveyor belt structure 41, and the conveying drive member 42 is configured to drive the conveyor belt structure 41 to perform a conveying movement along the second direction. The piece to be clamped 5 clamped by the clamping member 32 is configured to be conveyed on the conveyor belt structure 41. The position of the conveyor belt structure 41 in the first direction is configured to be flush with the position of the clamping member 32. When the clamping member 32 takes out the annular sheet structure, the conveyor belt structure 41 is configured to support both sides of the bottom of the annular sheet structure, so that the annular sheet structure is configured to be taken out smoothly and reduce deformation.

[0090] Taking the square ring as an example, the clamping module 3 is configured to be positioned and clamped on one side plate of the square ring, and the two adjacent side plates of the side plate on the square ring are configured to be laid flat on the corresponding conveyor belt structure 41 to facilitate smooth transportation of the square ring.

[0091] Optionally, a single conveyor drive member 42 may be provided, and multiple conveyor belt structures 41 may all be transmission-connected to the same conveyor drive member 42, with the same conveyor drive member 42 providing driving force, thereby improving the synchronization of the conveying motions of the multiple conveyor belt structures 41. Alternatively, multiple conveyor drives 42 may be provided, each of which is transmission-connected to the conveyor belt structure 41 in a one-to-one correspondence. The conveyor drive member 42 and the conveyor belt structure 41 are arranged on the same side of the clamping module 3, thereby effectively avoiding the position of the clamping module 3, shortening the length of the conveyor belt structure 41, and making the conveying more stable.

[0092] In this embodiment, a conveying bracket can be fixedly installed on the lifting platform 11, and the conveyor belt structure 41 is connected to the conveying bracket. The conveying bracket is configured to support the conveyor belt structure 41 from the lifting platform 11 to a position close to the clamping member 32, so as to facilitate the flattening of the part 5 to be clamped on the conveyor belt structure 41. The conveying bracket supports the conveyor belt structure 41 on both sides of the clamping module 3 and is configured to avoid the clamping module 3 to reduce the position interference between the clamping module 3 and the conveyor belt structure 41.

[0093] like Figures 1 to 3 As shown, in some embodiments, a protrusion 51 is provided on the annular sheet structure, and the protrusion 51 is provided to protrude outward from the side edge of the annular sheet structure along its own conveying direction. The protrusion 51 is configured to be clamped by the clamping member 32, that is, the annular sheet structure is configured to increase the clamping area between itself and the clamping member 32 by providing the protrusion 51, reduce the relative movement or separation with the clamping member 32, so that the clamping member 32 clamps the annular sheet structure more stably, thereby improving the accuracy of the clamping and conveying position.

[0094] The clamping member 32 includes a support frame 321, two clamping jaws 322, and a clamping cylinder 323. The support frame 321 is fixedly mounted on the transfer bracket 22. The support frame 321 is supported by the transfer bracket 22 and is stable in position. Each clamping jaw 322 has a connected clamping plate 3221 and a connecting arm 3222. The connecting arm 3222 is slidably connected to the support frame 321. The clamping plates 3221 of the two clamping jaws 322 are configured to clamp on both sides of the protrusion 51. The clamping plates 3221 are flat plate structures, so that the two clamping jaws 322 are configured to clamp and fix the annular sheet structure over a large area. The connecting arm 3222 is slidably connected to the support frame 321, which facilitates the reciprocating motion of the connecting arm 3222 in a first direction along its own sliding path, thereby improving the clamping accuracy of the clamping plate 3221 on the annular sheet structure.

[0095] The clamping cylinder 323 is set on the support frame 321, and the two clamping jaws 322 are both connected to the clamping cylinder 323 in a transmission manner. The clamping cylinder 323 is configured to drive the two clamping jaws 322 to move closer to or away from each other in a first direction, that is, the clamping cylinder 323 can have two force-applying ends, each force-applying end drives a clamping jaw 322 to move, and the clamping cylinder 323 can drive the clamping jaws 322 to move closer to or away from each other by pressurizing or depressurizing the clamping cylinder 323. The clamping cylinder 323 is used to drive the clamping jaws 322 to move, which has high precision, stable gripping force, and is flexible and convenient to use.

[0096] In other embodiments, the clamping wall of the clamping plate 3221 that contacts the object 5 to be clamped may be provided with anti-slip grooves to increase the friction between the object 5 to be clamped and the clamping plate 3221, facilitating displacement and disengagement. The clamping wall of the clamping plate 3221 may also be provided with a buffer layer. The buffer layer may be made of, but is not limited to, an elastic material such as rubber or silicone to facilitate flexible engagement between the clamping plate 3221 and the object 5 to be clamped.

[0097] like Figures 2 to 4 As shown, in some embodiments, the positioning member 31 includes a positioning block 312 and a positioning adjustment cylinder 311. The positioning adjustment cylinder 311 is fixedly set on the transfer bracket 22. The positioning block 312 is set on the positioning adjustment cylinder 311 and is transmission-connected to the positioning adjustment cylinder 311. The positioning adjustment cylinder 311 is configured to drive the positioning block 312 to move in the second direction, thereby adjusting the relative position of the positioning block 312 and the clamping member 32 in the second direction to adjust the clamping position of the clamping member 32 on the member 5 to be clamped.

[0098] like Figures 2 to 4 As shown, in some other embodiments, a plurality of limiting protrusions 313 are provided on the positioning block 312, and the plurality of limiting protrusions 313 are arranged at intervals on the surface of the positioning block 312, and the limiting protrusions 313 are configured to abut against the part to be clamped 5, that is, the layout path of the limiting protrusions 313 is the same as the edge contour of the part to be clamped 5. The purpose of providing the plurality of limiting protrusions 313 on the positioning block 312 is to form multi-point limits on the edge of the part to be clamped 5 to increase the overall positioning range, while reducing the contact area between the positioning block 312 and the part to be clamped 5, so that the positioning block 312 and the clamping part are more fitted.

[0099] In this embodiment, the limiting protrusion 313 may be, but is not limited to, cylindrical, square, or hemispherical, and is configured to reduce the contact area between the positioning block 312 and the object 5 to be clamped.

[0100] like Figures 4 to 6As shown, in some embodiments, the lifting drive member 12 includes a support 121, a lead screw 122, a lifting motor 123, and a lifting slider 124. The lifting platform 11 is slidably mounted on the support 121. The support 121 is configured to provide slidable support for the lifting platform 11, thereby improving the stability of the installation. The lead screw 122 is rotatably mounted on the support 121 and extends along a first direction. The lifting motor 123 is in driving connection with the lead screw 122, and the lifting motor 123 can drive the lead screw 122 to rotate. The lifting slider 124 is arranged on the screw 122, and the lifting slider 124 is fixedly connected to the lifting platform 11. The rotation of the screw 122 can drive the lifting slider 124 and the lifting platform 11 to move in the first direction. With this arrangement, the lifting motor 123 is started to drive the screw 122 to rotate forward or reverse, which can drive the lifting slider 124 to rise or fall in the first direction.

When the working cache mechanism 7 fails, for example, the material is exhausted or damaged, the lifting module 1 is configured to adjust the clamping module 3 to the backup cache mechanism 9 for material clamping, so as to ensure continuous conveying of the to-be-clamped parts 5 and reduce downtime.

[0119] In this embodiment, one or more backup cache mechanisms 9 may be provided, and the plurality of backup cache mechanisms 9 are configured to be spaced apart from the working cache mechanism 7 in the first direction.
