Description

Technical Field

[0001] This application relates to the field of material handling equipment technology, and in particular to a cuboid material clamping device. Background Technology

[0002] In automated production processes, material handling mechanisms are typically needed to move materials from one process stage to another for processing. For rectangular and heavy materials (such as battery cell modules), to ensure that the materials do not shift during handling, a first set of clamping components is used to clamp the front and back of the material, and a second set of clamping components is used to clamp the two sides of the material.

[0003] Because the movement direction of the first clamping assembly is perpendicular to that of the second clamping assembly, both assemblies are currently driven by corresponding drive components and transmission components. This results in the existing handling mechanism being relatively heavy, while the load on the handling mechanism is constant, thus limiting the weight of materials that the existing handling mechanism can handle. Utility Model Content

[0004] The purpose of this application is to provide a cuboid material clamping device to solve the problem of the large weight of existing cuboid material clamping devices.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application discloses a cuboid material clamping device, which includes a base, a drive mechanism, a first clamping mechanism, and a second clamping mechanism, wherein:

[0007] The first clamping mechanism includes two first clamping parts arranged in parallel, which can be installed on the base close to or far from each other along the first horizontal direction;

[0008] The second clamping mechanism includes two second clamping parts arranged in parallel. The two second clamping parts can be installed on the base close to or far from each other along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0009] The drive end of the drive mechanism is connected to at least one first clamping part and at least one second clamping part. The drive mechanism is configured to drive the two first clamping parts to move closer to each other in a first horizontal direction while simultaneously driving the two second clamping parts to move closer to each other in a second horizontal direction to clamp the cuboid material.

[0010] The drive mechanism is also configured to drive the two first clamping parts to move away from each other along a first horizontal direction while simultaneously driving the two second clamping parts to move away from each other along a second horizontal direction, so as to release the clamped cuboid material.

[0011] The first and second clamping mechanisms of the cuboid material clamping device proposed in this application share a single drive mechanism. The drive mechanism drives the two first clamping parts and the two second clamping parts to move closer or further apart synchronously to clamp or release the cuboid material. Compared with the existing clamping mechanisms, which are equipped with corresponding drive components and transmission components, the overall structure of the clamping device is simplified and the weight of the clamping device is reduced. In addition, it can be used with a conveying mechanism to convey materials with greater weight.

[0012] Optionally, the drive mechanism includes a drive member, two drive pulleys, a drive belt, at least one transmission assembly, and two first sliding members, wherein:

[0013] Two drive pulleys are spaced apart along a first horizontal direction and rotatably mounted on a base. A drive belt is sleeved on the two drive pulleys. The drive unit is configured to drive the drive belt to reciprocate along the first horizontal direction.

[0014] One of the first sliding members is fixedly connected to the belt body on the first side of the transmission belt, and the other first sliding member is fixedly connected to the belt body on the second side of the transmission belt. The two first clamping parts are fixedly connected to the two first sliding members respectively.

[0015] The transmission assembly is mounted on the transmission belt. The two follower ends of the transmission assembly are fixedly connected to the two second clamping parts respectively. When the transmission assembly moves in the first horizontal direction, it drives the two second clamping parts to move closer or further apart in the second horizontal direction.

[0016] By cooperating with the driving component, two transmission pulleys, and two first sliding components, the two first clamping parts are driven to move closer or further apart in the first horizontal direction; by setting the transmission components, the two second clamping parts are driven to move closer or further apart in the second horizontal direction while the two first clamping parts are driven to move closer or further apart in the first horizontal direction; a driving mechanism with a compact structure, low cost, high transmission efficiency, and high transmission accuracy is provided.

[0017] Optionally, the transmission assembly includes a slide plate and two second sliding members. The slide plate is fixedly connected to the belt body on the first side of the transmission belt. Two track grooves extending along the first horizontal direction are formed on the slide plate. The two track grooves are respectively located on two parts on both sides of the center line of the slide plate along the first horizontal direction. The first end of the two track grooves is equidistant from the center line of the slide plate along the first horizontal direction. The second end of the two track grooves is equidistant from the center line of the slide plate along the first horizontal direction. The distance from the first end of each track groove to the center line of the slide plate along the first horizontal direction is greater than the distance from the second end of the track groove to the center line of the slide plate along the first horizontal direction.

[0018] Each second slider is equipped with a follower wheel located in the corresponding track groove. Each second slider is fixedly connected to a second clamping part. When the follower wheel of one second slider is located at the first end of the corresponding track groove, the follower wheel of the other second slider is located at the first end of the corresponding track groove.

[0019] By creating two track grooves extending along the first horizontal direction on the skateboard and installing a follower wheel located in the corresponding track groove on each second sliding member, the movement of the skateboard along the first horizontal direction is converted into the movement of the two second sliding members moving closer or further apart along the second horizontal direction. At the same time, the transmission method using the follower wheel and track groove provides a transmission component with high transmission accuracy, smooth transmission, high mechanical efficiency and easy maintenance.

[0020] Optionally, the fixed end of the drive component is mounted on the base, and the drive end of the drive component is connected to the slide plate of any transmission component. The drive component is configured to drive the connected slide plate to reciprocate along a first horizontal direction.

[0021] or,

[0022] The drive unit is mounted on the base, and the drive end of the drive unit is connected to one of the transmission pulleys. The drive unit is configured to drive one of the transmission pulleys to rotate.

[0023] or,

[0024] The drive unit is mounted on the base, and the drive end of the drive unit is connected to the transmission belt. The drive unit is configured to drive the transmission belt to reciprocate along a first horizontal direction.

[0025] Three different drive configurations are provided to meet different application scenarios and assembly requirements.

[0026] Optionally, there are two transmission components and two sets of second clamping mechanisms. Each transmission component corresponds to one set of second clamping mechanisms. The driving component is configured to drive the transmission belt to reciprocate along the first horizontal direction so that the four second clamping parts of the two sets of second clamping mechanisms can be synchronously driven to move closer or further apart from each other along the second horizontal direction through the two transmission components.

[0027] By setting up two transmission components and two sets of second clamping mechanisms, the stability and reliability of clamping cuboid materials in the second horizontal direction are improved.

[0028] Optionally, the two second clamping parts of the two sets of second clamping mechanisms located outside the belt body on the first side of the transmission belt are symmetrically arranged along the centerline of the base in the second horizontal direction, and the two second clamping parts of the two sets of second clamping mechanisms located outside the belt body on the second side of the transmission belt are symmetrically arranged along the centerline of the base in the second horizontal direction.

[0029] The two second clamping parts of each set of second clamping mechanisms are staggered in the first horizontal direction and the second horizontal direction, and the two track grooves on the slide of each transmission component are located at opposite corners of the slide.

[0030] By setting up four second clamping parts in the two sets of second clamping mechanisms and setting up two trajectory grooves, the four second clamping parts of the two sets of second clamping mechanisms can move in a staggered manner in the first horizontal direction and the second horizontal direction, and can clamp the cuboid material in a staggered manner. This avoids interference when the four second clamping parts move, and is more suitable for clamping cuboid materials with smaller thickness. It occupies less space and also further improves the stability and reliability of clamping cuboid materials.

[0031] Optionally, the base is provided with a slide rail extending along a first horizontal direction, and two first sliding members and two transmission components are respectively slidably mounted on the slide rail via sliders.

[0032] By setting a slide rail on the base, the two first sliding members and the two transmission components are slidably mounted on the slide rail by sliders, which improves the smoothness of the movement of the first sliding members and transmission components along the first horizontal direction.

[0033] Optionally, the first clamping part includes a first clamping plate and a pushing block, wherein:

[0034] The first clamping plate is slidably installed below the base along the first horizontal direction. The first end of the first clamping plate is fixed on the corresponding first sliding member. The push block is installed at the second end of the first clamping plate and is located on the side of the first clamping plate close to the cuboid material.

[0035] When the two first clamping parts clamp the cuboid material, the pushing blocks of the two first clamping parts abut against both ends of the cuboid material in the first horizontal direction.

[0036] By fixing the first clamping plate to the corresponding first sliding member and installing the push block on the side of the first clamping plate close to the cuboid material, the cuboid material can be clamped at both ends in the first horizontal direction by the two push blocks. Under the premise of ensuring the stability and reliability of clamping, the first clamping part only needs to replace the push block after long-term use, which reduces the cost of use.

[0037] Optionally, the second clamping part includes a mounting base and a second clamping plate, wherein:

[0038] The mounting base is slidably mounted on the base along the second horizontal direction, and the second sliding member is fixedly connected to the corresponding mounting base;

[0039] The first end of the second clamping plate is mounted on the mounting base, and a support block is mounted on the side of the second end of the second clamping plate near the cuboid material. The support block is configured to support the bottom surface of the cuboid material on the side extending in the first horizontal direction.

[0040] When the cuboid material is clamped by the two second clamping parts, the second clamping plates of the two second clamping parts are respectively clamped on the two sides of the cuboid material in the second horizontal direction, and the bottom surfaces of the cuboid material on both sides extending along the first horizontal direction are supported by the support blocks.

[0041] By setting a second clamping plate on the mounting base and a support block on the second clamping plate, the bottom surface of the rectangular material is supported by the support block while the two second clamping parts clamp the two sides of the rectangular material, thus preventing the rectangular material from falling accidentally. This provides a second clamping part that is stable, reliable and safe.

[0042] Optionally, the second clamping part further includes a pressure plate and a second buffer assembly, wherein the first end of the second clamping plate is movably mounted on the mounting base, wherein:

[0043] The pressure plate is fixedly installed on the second clamping plate. The pressure plate is located above the support block, and the distance between the pressure plate and the support block is greater than the height of the cuboid material.

[0044] The second buffer assembly includes a lifting rod and a second elastic element. The first end of the lifting rod is buoyantly mounted on the mounting base via the second elastic element, and the second end of the lifting rod is fixedly connected to the pressure plate.

[0045] Through the cooperation of the pressure plate, the second elastic element and the lifting rod, when the conveying mechanism excessively presses down on the cuboid material, the floating lifting rod can absorb the excess pressure and prevent the cuboid material and the second clamping part from being crushed.

[0058] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] In automated production processes, material handling mechanisms are typically needed to move materials from one process stage to another for processing. For rectangular and heavy materials (such as battery cell modules), to ensure that the materials do not shift during handling, a first set of clamping components is used to clamp the front and back of the material, and a second set of clamping components is used to clamp the two sides of the material.

[0060] Because the movement direction of the first clamping assembly is perpendicular to that of the second clamping assembly, both assemblies are currently driven by corresponding drive components and transmission components. This results in the existing handling mechanism being relatively heavy, while the load on the handling mechanism is constant, thus limiting the weight of materials that the existing handling mechanism can handle.

[0061] Therefore, this application provides a cuboid material clamping device. Please refer to [link / reference]. Figure 1As shown, the cuboid material clamping device provided in this embodiment includes a base 10, a drive mechanism 20, a first clamping mechanism, and a second clamping mechanism. The first clamping mechanism includes two parallel first clamping parts 30, which can be clamped along a first horizontal direction (…). Figure 1 The second clamping mechanism includes two parallel second clamping parts 40, which can be mounted close to or far apart from each other along the second horizontal direction (X direction); Figure 1 The two clamping parts 30 and 40 are mounted on the base 10 in the Y direction, with the first horizontal direction perpendicular to the second horizontal direction. The driving end of the driving mechanism 20 is connected to at least one first clamping part 30 and at least one second clamping part 40. The driving mechanism 20 is configured to drive the two first clamping parts 30 to move closer to each other in the first horizontal direction while driving the two second clamping parts 40 to move closer to each other in the second horizontal direction to clamp the cuboid material 50. The driving mechanism 20 is also configured to drive the two first clamping parts 30 to move away from each other in the first horizontal direction while driving the two second clamping parts 40 to move away from each other in the second horizontal direction to release the clamped cuboid material 50.

[0062] Specifically, in this embodiment, the cuboid material 50 is a cuboid-structured battery cell module.

[0063] The first and second clamping mechanisms of the cuboid material clamping device proposed in this application share a single drive mechanism 20. The drive mechanism 20 drives the two first clamping parts 30 and the two second clamping parts 40 to move closer or further away from each other synchronously, so as to stably clamp or release the cuboid material 50. Compared with the existing two clamping mechanisms, which are equipped with corresponding drive components and transmission components, the overall structure of the clamping device is simplified and the weight of the clamping device is reduced. In addition, it can be used with the handling mechanism to handle materials with large weight.

[0064] Please see 1 and Figure 2As shown, in one embodiment, the drive mechanism 20 includes a drive member 21, two drive pulleys 22, a drive belt 23, at least one transmission assembly 24, and two first sliding members 25. The two drive pulleys 23 are rotatably mounted on the base 10 at intervals along a first horizontal direction. The drive belt 23 is sleeved on the two drive pulleys 22. The drive member 21 is configured to drive the drive belt 23 to reciprocate along the first horizontal direction. One of the first sliding members 25 is fixedly connected to the belt body on the first side of the drive belt 23, and the other first sliding member 25 is fixedly connected to the belt body on the second side of the drive belt 23. Two first clamping parts 30 are fixedly connected to the two first sliding members 25 respectively. The transmission assembly 24 is mounted on the drive belt 23. The two follower ends of the transmission assembly 24 are fixedly connected to the two second clamping parts 40 respectively. When the transmission assembly 24 moves in the first horizontal direction, it drives the two second clamping parts 40 to move closer or further away from each other in the second horizontal direction.

[0065] Through the cooperation of the driving component 21, two transmission pulleys 22 and two first sliding components 25, the two first clamping parts 30 are driven to move closer or further apart in the first horizontal direction; through the arrangement of the transmission assembly 24, the two second clamping parts 40 are driven to move closer or further apart in the second horizontal direction while the two first clamping parts 30 are driven to move closer or further apart in the first horizontal direction; a driving mechanism 20 with compact structure, low cost, high transmission efficiency and high transmission accuracy is provided.

[0066] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the transmission assembly 24 includes a slide plate 240 and two second sliding members 241. The slide plate 240 is fixedly connected to the belt body on the first side of the transmission belt 23. Two track grooves 242 extending along a first horizontal direction are formed on the slide plate 240. The two track grooves 242 are respectively located on two sides of the centerline of the slide plate 240 along the first horizontal direction. The first ends of the two track grooves 242 are equidistant from the centerline of the slide plate 240 along the first horizontal direction, and the second ends of the two track grooves 242 are also equidistant from the centerline of the slide plate 240 along the first horizontal direction. The distance from the first end of the track groove 242 to the center line of the slide plate 240 along the first horizontal direction is greater than the distance from the second end of the track groove 242 to the center line of the slide plate 240 along the first horizontal direction; each second slider 241 is equipped with a follower wheel 243 located in the corresponding track groove 242, and each second slider 241 is fixedly connected to a second clamping part 40. When the follower wheel 243 of one second slider 241 is located at the first end of the corresponding track groove 242, the follower wheel 243 of the other second slider 241 is located at the first end of the corresponding track groove 242.

[0067] By opening two track grooves 242 extending along the first horizontal direction on the slide plate 240 and installing a follower wheel 243 located in the corresponding track groove 242 on each second sliding member 241, the movement of the slide plate 240 along the first horizontal direction is converted into the movement of the two second sliding members 241 moving closer or further apart along the second horizontal direction. At the same time, the transmission method of the follower wheel 243 and the track groove 242 is adopted to provide a transmission component 24 with high transmission accuracy, smooth transmission, high mechanical efficiency and easy maintenance.

[0068] As shown in the figure, in one embodiment, the fixed end of the drive member 21 is mounted on the base 10, and the drive end of the drive member 21 is connected to the slide plate 240 of any transmission component 24. The drive member 21 is configured to drive the connected slide plate 240 to reciprocate along a first horizontal direction.

[0069] Specifically, the drive component 21 is a cylinder.

[0070] A driving method is provided in which a driving component 21 drives a sliding plate 240 to reciprocate along a first horizontal direction, thereby driving a transmission belt 23 to reciprocate along the first horizontal direction.

[0071] In one embodiment, the drive member 21 is mounted on the base 10, and the drive end of the drive member 21 is connected to one of the transmission pulleys 22. The drive member 21 is configured to drive one of the transmission pulleys 22 to rotate.

[0072] A driving method is provided in which the driving component 21 drives the transmission pulley 22 to rotate, thereby driving the transmission belt 23 to reciprocate along a first horizontal direction.

[0073] In one embodiment, the drive member 21 is mounted on the base 10, and the drive end of the drive member 21 is connected to the transmission belt 23. The drive member 21 is configured to drive the transmission belt 23 to reciprocate along a first horizontal direction.

[0074] A driving method is provided in which the driving component 21 directly drives the transmission belt 23 to reciprocate along a first horizontal direction.

[0075] In one implementation, there are two transmission components 24 and two sets of second clamping mechanisms. Each transmission component 24 corresponds to one set of second clamping mechanisms. The driving member 21 is configured to drive the transmission belt 23 to reciprocate along the first horizontal direction, so as to synchronously drive the four second clamping parts 40 of the two sets of second clamping mechanisms to move closer or further away from each other along the second horizontal direction through the two transmission components 24.

[0076] By setting up two transmission components 24 and two sets of second clamping mechanisms, the stability and reliability of clamping the cuboid material 50 in the second horizontal direction are improved.

[0077] In one embodiment, the two second clamping parts 40 of the two sets of second clamping mechanisms located outside the belt body on the first side of the transmission belt 23 are symmetrically arranged along the centerline of the base 10 in the second horizontal direction. The two second clamping parts 40 of the two sets of second clamping mechanisms located outside the belt body on the second side of the transmission belt 23 are symmetrically arranged along the centerline of the base 10 in the second horizontal direction. The two second clamping parts 40 of each set of second clamping mechanisms are staggered in the first horizontal direction and the second horizontal direction. The two track grooves 242 on the slide plate 240 of each transmission assembly 24 are located at opposite corners of the slide plate 240.

[0078] By setting up four second clamping parts 40 in the two sets of second clamping mechanisms and two trajectory grooves 242, the four second clamping parts 40 in the two sets of second clamping mechanisms can move in a staggered manner in the first horizontal direction and the second horizontal direction, and can clamp the cuboid material 50 in a staggered manner. This avoids interference when the four second clamping parts 40 move, and is more suitable for clamping cuboid material 50 with a small thickness. It occupies less space and further improves the stability and reliability of clamping cuboid material 50.

[0079] In one embodiment, a slide rail 51 extending along a first horizontal direction is provided on the base 10, and two first sliding members 25 and two transmission components 24 are respectively slidably mounted on the slide rail 51 by sliders.

[0080] By setting a slide rail 51 on the base 40, the two first sliding members 25 and the two transmission components 24 are respectively slidably mounted on the slide rail 51 by sliders, which improves the smoothness of the movement of the first sliding members 25 and the transmission components 24 along the first horizontal direction.

[0081] Please see Figure 1 and Figure 4 As shown, in one embodiment, the first clamping part 30 includes a first clamping plate 31 and a pushing block 32. The first clamping plate 31 is slidably mounted below the base 10 along a first horizontal direction. The first end of the first clamping plate 31 is fixed on the corresponding first sliding member 25. The pushing block 32 is mounted on the second end of the first clamping plate 31 and is located on the side of the first clamping plate 31 close to the cuboid material 50. When the two first clamping parts 30 clamp the cuboid material 50, the pushing blocks 32 of the two first clamping parts 30 abut against both ends of the cuboid material 50 in the first horizontal direction.

[0082] Specifically, the push block 32 is made of a material with a hardness lower than that of the cuboid material 50, in order to avoid damaging the cuboid material 50.

[0083] By fixing the first clamping plate 31 to the corresponding first sliding member 25 and installing the push block 32 on the side of the first clamping plate 31 close to the cuboid material 50, the two ends of the cuboid material 50 are clamped in the first horizontal direction by the two push blocks 32. Under the premise of ensuring the stability and reliability of clamping, the first clamping part 30 only needs to replace the push block 32 after long-term use, which reduces the cost of use.

[0084] In one embodiment, at least one push block 32 is mounted on the first clamping plate 31 via a first buffer assembly. The first buffer assembly includes at least one guide rod 33 and at least one first elastic element 34. The guide rod 33 is reciprocally mounted on the corresponding first clamping plate 31 in a first horizontal direction. The first end of the guide rod 33 is fixed to the push block 32, and the second end of the guide rod 33 is provided with a limiting head 35 for limiting the movement stroke of the guide rod 33. Each guide rod 33 is fitted with a first elastic element 34. The first end of the first elastic element 34 abuts against the push block 32, and the second end of the first elastic element 34 abuts against the first clamping plate 31.

[0085] Specifically, the first elastic element 34 is a helical spring.

[0086] By setting the first buffer component, the two push blocks 32 are elastically clamped on the cuboid material 50 while ensuring the stability and reliability of the clamping of the two push blocks 32, thus avoiding hard contact between the two push blocks 32 and the cuboid material 50 and causing pinching damage.

[0087] Please see Figure 1 and Figure 6 As shown, in one embodiment, the second clamping part 40 includes a mounting base 41 and a second clamping plate 42. The mounting base 41 is slidably mounted on the base 10 along the second horizontal direction, and the second sliding member 241 is fixedly connected to the corresponding mounting base 41. The first end of the second clamping plate 42 is mounted on the mounting base 41, and a support block 43 is mounted on the side of the second end of the second clamping plate 42 near the cuboid material 50. The support block 43 is configured to support the bottom surface of the cuboid material 50 on the side extending along the first horizontal direction. When the two second clamping parts 40 clamp the cuboid material 50, the second clamping plates 42 of the two second clamping parts 40 are respectively clamped on the two sides of the cuboid material 50 in the second horizontal direction, and the support block 43 supports the bottom surfaces of the two sides of the cuboid material 50 extending along the first horizontal direction.

[0088] Specifically, a first sliding guide pair is provided between the mounting base 41 and the base 10. The first sliding guide pair includes a first linear guide rail 52 and a first slider 53. The first linear guide rail 52 is fixed to the base 10 along the second horizontal direction, and the first slider 53 is fixed to the mounting base 41 and fitted onto the first linear guide rail 52. By providing the first sliding guide pair, the stability of the mounting base 41 moving along the second horizontal direction is improved.

[0089] By setting a second clamping plate 42 on the mounting base 41 and a support block 43 on the second clamping plate 42, it is possible to clamp the two sides of the cuboid material 50 with the two second clamping parts 40 while supporting the bottom surface of the cuboid material 50 with the support block 43, so as to prevent the cuboid material 50 from falling accidentally. This provides a second clamping part 40 with stable and reliable clamping and high safety.

[0090] In one embodiment, the second clamping part 40 further includes a pressure plate 44 and a second buffer assembly. The first end of the second clamping plate 42 is movably mounted on the mounting base 41, and the pressure plate 44 is fixedly mounted on the second clamping plate 42. The pressure plate 44 is located above the support block 43, and the distance between the pressure plate 44 and the support block 43 is greater than the height of the cuboid material 50. The second buffer assembly includes a lifting rod 45 and a second elastic element (not shown in the figure). The first end of the lifting rod 45 is movably mounted on the mounting base 41 through the second elastic element, and the second end of the lifting rod 45 is fixedly connected to the pressure plate 44.

[0091] Specifically, the second elastic element is a coil spring.

[0092] Specifically, a second sliding guide pair is provided between the second clamping plate 42 and the mounting base 41. The second sliding guide pair includes a second linear guide rail 54 and a second slider 55. The second linear guide rail 54 is vertically fixed on the second clamping plate 42, and the second slider 55 is fixed on the mounting base 41 and fitted onto the second linear guide rail 54. By providing the second sliding guide pair, the stability of the second clamping plate 42 floating up and down is improved.

[0093] In practical applications, after the conveying mechanism moves the cuboid material 50 to the discharge position through the second clamping mechanism, in order to ensure that the cuboid material 50 is close to the discharge position, the conveying mechanism will press the cuboid material 50 down slightly. Through the cooperation of the pressure plate 44, the second elastic element and the lifting rod 45, when the conveying mechanism presses down the cuboid material 50 excessively, the floating lifting rod 45 can absorb the excess pressure and prevent the cuboid material 50 and the second clamping part 40 from being crushed.

[0094] Please see Figure 2 , Figure 3 and Figure 5As shown, the general process of the cuboid material clamping device proposed in this application for clamping cuboid material is as follows: the driving member 21 drives one of the sliding plates 240 to move along the first horizontal direction. Since both sliding plates 240 are fixedly connected to the belt body on the first side of the transmission belt 23, the transmission belt 23 will move along the first horizontal direction and drive the other sliding plate 240 to move synchronously along the first horizontal direction. Then, through the cooperation of the follower wheel 243 and the track groove 242, the four second clamping parts 40 of the two sets of second clamping mechanisms will move closer to each other along the second horizontal direction, and the cuboid material 50 will be clamped by the four second clamping parts 40 in the second horizontal direction. Since the two first sliding members 25 are fixed on the first side and the second side of the transmission belt 23 respectively, when the transmission belt 23 moves along the first horizontal direction, it will drive the two first sliding members 25 to move closer to each other along the first horizontal direction, and then drive the two first clamping parts 30 to clamp the two ends of the cuboid material 50 in the first horizontal direction.

[0095] The cuboid material clamping device proposed in this application has the following advantages:

[0096] 1) Under the premise of achieving stable and reliable clamping of cuboid materials, the first clamping mechanism and the second clamping mechanism share a set of drive mechanisms, which simplifies the overall structure of the clamping device, reduces the weight of the clamping device, and thus, in conjunction with the handling mechanism, can handle materials with large weight.

[0097] 2) The overall structure of the drive mechanism is compact, low in cost, high in transmission efficiency, and high in transmission precision.

[0098] 3) By setting up two transmission components and two sets of second clamping mechanisms, the stability and reliability of clamping cuboid materials are improved.

[0099] 4) The second clamping plate, together with the support block, plays a dual role of clamping and supporting, preventing the rectangular material from falling accidentally and improving the stability and safety of clamping.

[0100] 5) Both the first clamping part and the second clamping part are equipped with buffer components to avoid hard contact with the cuboid material and to protect the cuboid material.

[0101] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
