The clamping fixture achieves positioning under the action of the positioning member, ultimately achieving the purpose of clamping and positioning, improving clamping efficiency, and providing high clamping accuracy.

[0040] The following describes some embodiments of this application in detail with reference to the accompanying drawings.

[0041] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The clamping device 100 provided in the embodiments of this application is used to clamp multiple stacked and adhered products 10 in the incoming materials, each product 10 being provided with a positioning hole 11 (see...). Figure 4 Furthermore, an adhesive portion (not shown) is provided between two adjacent products 10. It is understood that in this embodiment, the volume of the adhesive portion between the two products 10 is smaller than the volume of the product 10, and the adhesive portion is easily damaged under the action of external force, causing the two adjacent products 10 to separate.

[0042] In some embodiments, the clamping device 100 includes a material picking mechanism 20, a material dispensing mechanism 30, a clamping mechanism 40, and a positioning mechanism 50.

[0043] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 The material handling mechanism 20 includes a material handling platform 21, a lifting member 22, a clamping member 23, and a material handling member 24. The material handling platform 21 has at least one sliding cavity 211 and a first through hole 212 communicating with the sliding cavity 211. The lifting member 22 is slidably connected to the material handling platform 21 and is configured to move multiple stacked and adhered products 10 toward the material handling platform 21 and partially extend out of the first through hole 212. The clamping member 23 is slidably disposed in the sliding cavity 211 and is configured to extend from the sliding cavity 211 into the first through hole 212 to clamp a portion of the products 10 located within the first through hole 212 by cooperating with the hole wall of the first through hole 212. The material handling member 24 is movable relative to the material handling platform 21 and is configured to disconnect the adhered portion and grasp one of the products 10 located within the first through hole 212, separating it from its adjacent products 10. In this embodiment, the picking component 24 is preferentially used to pick up the topmost product 10 among multiple stacked products 10.

[0044] Please refer to the following: Figure 1 , Figure 6 and Figure 7 The feeding mechanism 30 includes a feeding platform 31 and a support fixture 32. The feeding platform 31 is located on one side of the picking platform 21. The support fixture 32 is detachably connected to the picking platform 21. The support fixture 32 is provided with a plurality of placement holes 321, which are configured to receive the product 10 gripped by the picking component 24.

[0045] Please refer to the following: Figure 1 , Figure 8 and Figure 9The clamping mechanism 40 includes a clamping platform 41 and a clamping fixture 42. The clamping platform 41 is located on the side of the unloading platform 31 away from the unloading platform 21, and is used to support and position the support fixture 32. The clamping fixture 42 includes a body 421 and a plurality of protrusions 422. The body 421 presses against the side of the support fixture 32 away from the clamping platform 41, and the plurality of protrusions 422 are spaced apart and connected to the side of the body 421 facing the support fixture 32. The protrusions 422 are configured to extend into the positioning hole 11 of the product 10 and hold the product 10 so that the product 10 is disengaged from the support fixture 32.

[0046] Please refer to the following: Figure 1 and Figure 10 The positioning mechanism 50 includes a positioning platform 51 and a positioning element 52. The positioning platform 51 is located on the side of the clamping platform 41 away from the unloading platform 31, and is used to support the clamping fixture 42. The end of the body 421 is provided with a second through hole 4211. One end of the positioning element 52 is connected to the positioning platform 51, and the other end passes through the second through hole 4211 to limit the clamping fixture 42 between the positioning element 52 and the positioning platform 51.

[0047] In the aforementioned clamping device 100, the product 10 is connected to the lifting member 22 and extends into the first through hole 212 under the drive of the lifting member 22. The clamping member 23 cooperates with the hole wall of the first through hole 212 to clamp the product 10, reducing the risk of product 10 shifting during the material handling process. After the material handling member 24 picks up multiple products 10 sequentially from the material handling mechanism 20 onto the supporting fixture 32, the products 10 are arranged one by one in the placement hole 321. The protrusion 422 on the clamping fixture 42 extends into the positioning hole 11 of the product 10 located on the supporting fixture 32, so that the product 10 is clamped from the supporting fixture 32 onto the clamping fixture 42. The clamping fixture 42 is positioned under the action of the positioning member 52, ultimately achieving the purpose of clamping and positioning, improving clamping efficiency, and achieving high clamping accuracy.

[0048] In this embodiment, the material handling platform 21 is provided with four first through holes 212, each of which is equipped with a clamping member 23, and the lifting member 22 can simultaneously control the product 10 located in the four first through holes 212 to rise. Optionally, the number of first through holes 212 can be any one of 1, 2, 3, 5, 6, etc., to increase the number of products 10 that the material handling mechanism 20 can clamp at the same time and improve the material handling efficiency.

[0049] Please refer to the following: Figure 2 and Figure 3In some embodiments, the lifting member 22 includes a lead screw 221, a lifting portion 222, and at least one positioning portion 223. The lead screw 221 is rotatably connected to the picking platform 21 along an axis. The lifting portion 222 is connected to the end of the lead screw 221 away from the picking platform 21 and is configured to move toward or away from the picking platform 21 in a first direction Z as the lead screw 221 rotates about its axis. The positioning portion 223 is connected to the side of the lifting portion 222 facing the picking platform 21. The positioning portion 223 is used to extend into the positioning hole 11 of the product 10 to position the end of the product 10 near the lifting portion 222. The positioning portion 223 is used to cooperate with the clamping member 23 to clamp the two ends of multiple stacked products 10, improving the stability of the product 10 in the first direction Z, thereby reducing the risk of the product 10 shifting during the picking process by the picking member 24. With the above settings, when the lead screw 221 rotates relative to the material picking platform 21, it can drive the lifting part 222 to rise or fall. When the lifting part 222 rises, the lifting part 222 drives multiple products 10 to pass through the first through hole 212 in sequence, so that the clamping member 23 located in the first through hole 212 can clamp the product 10, reducing the risk of the product 10 shifting during the material picking process.

[0050] In this embodiment, the material handling mechanism 20 further includes a wrench 25, which is detachably connected to a lead screw 221. The lead screw 221 rotates around its axis via the wrench 25, and the wrench 25 can be rotated by external automated equipment. Optionally, in other embodiments, the lead screw 221 can be connected to a motor to rotate, thereby automating the lifting process of the lifting member 22 lifting the product 10.

[0051] Please continue reading. Figure 2 and Figure 3 In some embodiments, the clamping member 23 includes at least one clamping portion 231, a pushing portion 232, and an elastic portion 233. The clamping portion 231 slides between the sliding cavity 211 and the first through hole 212 along a second direction X. The clamping portion 231 has a clamping surface 2311 and a first wedge surface 2312 disposed opposite to each other in the second direction X. The clamping surface 2311 is configured to clamp the product 10 by cooperating with the wall of the first through hole 212. The pushing portion 232 moves within the sliding cavity 211 along a first direction Z. The pushing portion 232 has at least one second wedge surface 2321 in the second direction X. The second wedge surface 2321 is configured to abut against the first wedge surface 2312 when the pushing portion 232 moves in a direction away from the lifting portion 222, so that the clamping portion 231 moves toward the product 10. The elastic portion 233 elastically abuts against the cavity wall of the clamping portion 231 and the sliding cavity 211. The elastic portion 233 is configured to abut the clamping portion 231 towards the pushing portion 232, with the first direction Z and the second direction X perpendicular to each other. When the pushing portion 232 moves towards the lifting portion 222, the elastic portion 233 pushes the clamping portion 231 to reset, so that the clamping portion 231 can perform the next clamping action.

[0052] In this embodiment, the pushing part 232 is a locking screw. The pushing part 232 can also be moved in the first direction Z by the wrench part 25, which can be rotated by external automated equipment.

[0053] In this embodiment, there are two clamping parts 231, which are spaced apart along the second direction X. The two clamping parts 231 are located on both sides of the pushing part 232, so that the pushing part 232 can simultaneously push the two clamping parts 231 to clamp two stacked products 10. It can be understood that the pushing part 232 has two second wedge surfaces 2321 that are arranged opposite each other in the second direction X, and each second wedge surface 2321 corresponds to a clamping part 231.

[0054] Specifically, when the pushing part 232 moves away from the lifting part 222 under the drive of the wrench part 25, the two second inclined wedge surfaces 2321 on the pushing part 232 simultaneously push the two clamping parts 231 to move in opposite directions along the second direction X, respectively cooperating with the hole wall of the first through hole 212 to clamp the two stacked products 10, thereby increasing the number of products 10 clamped by the clamping part 23.

[0055] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the picking member 24 is provided with a picking end 241, which includes a base plate 2411, a first connecting plate 2412, a second connecting plate 2413, a first stop plate 2414, and a second stop plate 2415. The first stop plate 2414 is connected to the end of the first connecting plate 2412 away from the base plate 2411, and the second stop plate 2415 is connected to the end of the second connecting plate 2413 away from the base plate 2411. The first stop plate 2414 and the second stop plate 2415 are spaced apart. A picking groove 2416 is formed between the base plate 2411, the first connecting plate 2412, the second connecting plate 2413, the first stop plate 2414, and the second stop plate 2415. The picking groove 2416 is used to receive the product 10. The first stop plate 2414 and the second stop plate 2415 are configured to clamp between the product 10 and its adjacent products when the picking member 24 picks up the product 10. When the material picking trough 2416 approaches the product 10, it picks up the top product 10 to achieve the purpose of picking up the material.

[0056] Optionally, the material handling component 24 may employ a mechanical gripper or a suction nozzle to grasp the product 10.

[0057] Please refer to the following: Figure 3 , Figure 4 and Figure 5In some embodiments, the picking end 241 is provided with a first opening 2417 and two second openings 2418 communicating with the picking groove 2416. The first opening 2417 is formed between the first stop plate 2414 and the second stop plate 2415, and is configured to allow the adhesive portion to pass through when the product 10 is located in the picking groove 2416. The two second openings 2418 are formed at both ends of the first opening 2417, and are configured to allow the product 10 to pass through. With the above configuration, when the picking member 24 picks up the product 10, the picking end 241 first approaches the uppermost product 10, and the picking groove 2416 in the picking end 241 remains on the same plane as the uppermost product 10 in the second direction X. The picking member 24 moves along the second direction X, at which time the product 10 can enter the picking groove 2416 through either of the second openings 2418. At the same time, the adhesive part enters the first opening 2417, so that when the picking member 24 moves the product 10 located in the picking groove 2416, the product 10 cannot be separated from the picking groove 2416, and the adhesive part breaks under the pulling force of the picking member 24, so that the product 10 in the picking groove 2416 is separated from the other product 10 it is attached to.

[0058] Please refer to the following: Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments, the support fixture 32 is further provided with a plurality of protrusions 322, which are located on one side of the placement hole 321. The protrusions 322 are configured to extend from the first opening 2417 into the picking groove 2416 when the picking member 24 moves the product 10 to the placement hole 321, so that the protrusions 322 abut against the product 10 and cause the product 10 to fall into the placement hole 321. With the above configuration, the protrusions 322 extend from the first opening 2417 into the picking groove 2416, and at the same time, during the translational movement of the picking member 24, the protrusions 322 continuously abut against the product 10 located in the picking groove 2416 until the product 10 is pushed out of the picking groove 2416 and falls into the placement hole 321, thereby achieving the purpose of the picking member 24 discharging material.

[0059] In this embodiment, each storage hole 321 has a protrusion 322 on both sides, so that the material picker 24 can hold the product 10 through any one of the protrusions 322, thereby improving the material feeding efficiency.

[0060] Please refer to the following: Figure 8 , Figure 9 and Figure 11In some embodiments, the feeding mechanism 30 further includes a first circular positioning pin 33 and a first square positioning pin 34, which are respectively connected to both ends of the feeding platform 31. Correspondingly, the two ends of the support fixture 32 are provided with a first circular hole 323 and a first square hole 324. When the support fixture 32 is placed on the surface of the feeding platform 31, the first circular positioning pin 33 extends into the first circular hole 323 and the first square positioning pin 34 extends into the first square hole 324, reducing the risk of the support fixture 32 moving relative to the feeding platform 31 and thus deviating from its placement position, thereby improving the stability of the support fixture 32 on the feeding platform 31.

[0061] Please refer to the following: Figure 9 , Figure 12 and Figure 13 In some embodiments, the clamping mechanism 40 further includes an inner support member 43. A sliding groove 4212 is provided on the side of the body 421 facing away from the clamping platform 41, and an inner support groove 4221 communicating with the sliding groove 4212 is provided on the side of the protrusion 422 facing away from the clamping platform 41. Each protrusion 422 includes an adjacently arranged fixed portion 4222 and a movable portion 4223. The fixed portion 4222 is fixedly connected to the body 421 and is used to abut against one side wall of the positioning hole 11. The movable portion 4223 is elastically connected to the body 421. The inner support member 43 moves along a first direction Z between the sliding groove 4212 and the inner support groove 4221. The inner support member 43 is configured to slide from the sliding groove 4212 into the inner support groove 4221 to push the movable portion 4223 away from the fixed portion 4222, so that the movable portion 4223 abuts against the other side wall of the positioning hole 11. The inner support 43 pushes the movable part 4223 to cooperate with the fixed part 4222 to abut against the hole wall of the positioning hole 11, so that the protrusion 422 can adapt to products 10 with different positioning hole 11 diameters, thereby improving the versatility of the clamping fixture 42.

[0062] Please continue reading. Figure 9 , Figure 12 and Figure 13 In this embodiment, the clamping mechanism 40 further includes a driving member 44, a screw 45, and a rotating member 46 (see Figure 46). Figure 12The drive member 44 is connected to the clamping platform 41, the screw 45 is located in the inner support groove 4221 and connected to the inner support member 43, one end of the rotating member 46 is connected to the transmission end of the drive member 44, the drive member 44 is used to drive the rotating member 46 to rotate, and the other end passes through the clamping platform 41, the bearing fixture 32 and the body 421 in sequence to extend into the sliding groove 4212 to connect to the inner support member 43. When the rotating member 46 rotates, the inner support member 43 can move along the first direction Z. When the inner support member 43 pushes the movable part 4223 to deform the movable part 4223, the movable part 4223 is reset when the inner support member 43 moves away from the movable part 4223. It can be understood that when the size of the protrusion 422 and the positioning hole 11 are exactly matched, the inner support member 43 does not need to push the movable part 4223 to deform further.

[0063] Please refer to the following: Figure 8 , Figure 9 and Figure 12 In some embodiments, the clamping mechanism 40 further includes a limiting member 47 connected to the side of the body 421 facing the clamping platform 41. The limiting member 47 has a plurality of limiting holes 471, each corresponding to a protrusion 422. The fixed part 4222 and the movable part 4223 pass through the limiting holes 471 to extend into the positioning hole 11 of the product 10. The limiting member 47 restricts the distance of the movable part 4223 away from the fixed part 4222, thereby reducing the risk of deformation of the product 10 when the inner support member 43 pushes the movable part 4223 away from the fixed part 4222 by too much.

[0064] Please refer to the following: Figure 8 and Figure 9 In some embodiments, the clamping mechanism 40 further includes a pressing member 48, which is rotatably connected to the clamping platform 41. The pressing member 48 is configured to abut against the side of the limiting member 47 away from the body 421 when the clamping fixture 42 presses against the carrying fixture 32. This configuration reduces the risk of movement of the clamping fixture 42 in the first direction Z, improving the stability of the clamping fixture 42 during the clamping of the product 10.

[0065] Please continue reading. Figure 8 and Figure 9 In some embodiments, the clamping mechanism 40 further includes a second circular locating pin 49 and a second square locating pin 491, which are respectively connected to both ends of the clamping platform 41. Accordingly, when the support fixture 32 is placed on the surface of the clamping platform 41, the second circular locating pin 49 extends into the first circular hole 323, and the second square locating pin 491 extends into the first square hole 324, reducing the risk of the support fixture 32 moving relative to the clamping platform 41 and thus shifting its placement position, thereby improving the stability of the support fixture 32 on the clamping platform 41.

[0066] Correspondingly, the two ends of the body 421 are provided with a second circular hole 4213 and a second square hole 4214. When the clamping fixture 42 is placed on the surface of the support fixture 32, the second circular positioning pin 49 extends into the second circular hole 4213 and the second square positioning pin 491 extends into the second square hole 4214, reducing the risk of the clamping fixture 42 moving relative to the support fixture 32 and thus shifting its placement position, thereby improving the stability of the clamping fixture 42 on the support fixture 32.

[0067] Please refer to the following: Figure 1 , Figure 10 and Figure 14 In some embodiments, the positioning member 52 includes a driving part 521, a positioning rod 522, and a limiting part 523. The driving part 521 is connected to the positioning platform 51. The positioning rod 522 is connected to the transmission end of the driving part 521. The positioning rod 522 is configured to be telescopically connected to the positioning platform 51 along a first direction Z under the drive of the driving part 521, or the positioning rod 522 is further configured to rotate from a first state 524 relative to the positioning platform 51 to a second state 525 under the drive of the driving part 521. The limiting part 523 is connected to the end of the positioning rod 522 away from the driving part 521. The limiting part 523 in the first state 524 is configured to move through the second through hole 4211 to the side of the clamping fixture 42 away from the positioning platform 51. The limiting part 523 in the first state 524 is further configured to rotate to the second state 525 to abut against the side of the clamping fixture 42 away from the positioning platform 51. Along the first direction Z, the projection of the limiting portion 523 in the second state 525 overlaps with the projection of the main body 421. Through this arrangement, the positioning member 52 improves the stability of the clamping fixture 42 when it is positioned on the positioning platform 51. It is understood that along the first direction Z, the projection of the limiting portion 523 in the first state 524 is located within the projection range of the second through hole 4211.

[0068] Please refer to the following: Figure 10 and Figure 14 In some embodiments, the positioning mechanism 50 further includes a third circular positioning pin 53 and a third square positioning pin 54, which are respectively connected to both ends of the positioning platform 51. When the clamping fixture 42 is placed on the surface of the positioning platform 51, the third circular positioning pin 53 extends into the second circular hole 4213, and the third square positioning pin 54 extends into the second square hole 4214, reducing the risk of the clamping fixture 42 moving relative to the positioning platform 51 and thus deviating from its placement position, thereby improving the stability of the clamping fixture 42 on the positioning platform 51.

[0069] The specific steps for clamping product 10 with clamping device 100 include: I. Material handling mechanism 20 The steps for the material handling mechanism 20 to pick up product 10 include: S1. When the lead screw 221 in the lifting member 22 rotates relative to the material picking platform 21, it drives the lifting part 222 to rise along the first direction Z. When the lifting part 222 rises, it drives multiple products 10 to pass through the first through hole 212.

[0070] S2. The pushing part 232 inside the clamping member 23 rises along the first direction Z so that the second inclined wedge surface 2321 on the pushing part 232 abuts against the first inclined wedge surface 2312 of the clamping part 231, thereby causing the clamping part 231 to move toward the wall of the first through hole 212, and the clamping part 231 cooperates with the wall of the first through hole 212 to clamp the product 10.

[0071] S3. The picking component 24 drives the picking end 241 to approach the uppermost product 10. The product 10 enters the picking groove 2416 through the second opening 2418, while the adhesive part enters the first opening 2417. The picking component 24 moves away from the picking platform 21. The adhesive part breaks under the pulling force of the picking component 24, so that the product 10 in the picking groove 2416 is separated from the other product 10 it is attached to, thus completing the picking process.

[0072] II. Feeding Mechanism 30 The steps of the feeding mechanism 30 in feeding down product 10 include: S1. Install the support fixture 32 onto the unloading platform 31, and position the support fixture 32 on the unloading platform 31 by inserting the first circular positioning pin 33 into the first circular hole 323 and the first square positioning pin 34 into the first square hole 324.

[0073] S2. The protrusion 322 extends into the material picking groove 2416 from the first opening 2417. The material picking component 24 moves horizontally, so that the protrusion 322 continuously holds the product 10 located in the material picking groove 2416 until the product 10 is pushed out of the material picking groove 2416 and falls into the storage hole 321, thus completing the material feeding process.

[0074] III. Clamping Mechanism 40 The clamping mechanism 40 clamps product 10 in the following steps: S1. Move the support fixture 32 from the unloading platform 31 to the clamping platform 41, and position the support fixture 32 on the clamping platform 41 by inserting the second circular positioning pin 49 into the first circular hole 323 and the second square positioning pin 491 into the first square hole 324.

[0075] S2. Place the clamping fixture 42 on top of the supporting fixture 32, while the protrusion 322 extends into the positioning hole 11 of the product 10.

[0076] S3, the driving member 44 drives the rotating member 46 to rotate, so that the rotating member 46 drives the screw 45 located in the sliding groove 4212 and connected to the inner support member 43 to rotate. As a result, the screw 45 drives the inner support member 43 to move in the direction of the clamping platform 41. The inner support member 43 extends from the sliding groove 4212 into the inner support groove 4221 to push the movable part 4223 to deform in the direction away from the fixed part 4222, thereby cooperating with the fixed part 4222 to abut against the two side walls of the positioning hole 11 respectively.

[0077] S4. The pressing part 48 rotates relative to the clamping platform 41, moves to the top of the clamping fixture 42 and abuts against the clamping fixture 42, and reduces the gap between the clamping fixture 42 and the bearing fixture 32, thereby improving the stability of the clamping fixture 42 when clamping the product 10, thus completing the clamping process.

[0078] IV. Positioning Mechanism 50 The steps of positioning mechanism 50 and positioning clamping fixture 42 include: S1. The clamping fixture 42 is moved from the clamping mechanism 40 to the positioning platform 51. The driving unit 521 drives the positioning rod 522 and the limiting part 523 connected to the positioning rod 522 to protrude relative to the positioning platform 51 and can pass through the second through hole 4211 into the side of the clamping fixture 42 away from the positioning platform 51. At this time, the limiting part 523 is in the first state 524. At the same time, the positioning mechanism 50 positions the clamping fixture 42 on the positioning platform 51 by the third circular positioning pin 53 extending into the second circular hole and the third square positioning pin 54 extending into the second square hole.

[0079] S2, the drive unit 521 drives the positioning rod 522 and the limiting part 523 connected to the positioning rod 522 to rotate again, so that the limiting part 523 rotates from the first state 524 to the second state 525 to hold the clamping fixture 42, thus completing the process of positioning the clamping fixture 42, so that the subsequent process can process the product 10 located on the clamping fixture 42.

[0080] The above-mentioned clamping device 100 has a simple structure and low cost. It can perform continuous processing of multiple products 10 in one clamping, with high processing efficiency. At the same time, the entire clamping device 100 can realize fully automatic processing and production, improve clamping efficiency, and achieve stable and reliable clamping of products 10.

[0081] 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 spirit and essence of this application fall within the scope of this application's disclosure.
