DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0032] Reference Figures 1 to 3 As shown, some embodiments of the present disclosure provide a clamping mechanism, including a support plate 1, a driving assembly and at least two groups of clamping jaws. The support plate 1 is a plate-like structure, which can be made of plastic or metal. The clamping jaws can be two or more groups, and the clamping jaws are all arranged on the support plate 1, and each group of clamping jaws is used to clamp different workpieces. The driving assembly is arranged on the support plate 1, and the driving assembly is respectively connected to the multiple groups of clamping jaws to drive each group of clamping jaws to clamp different workpieces.

[0033] The clamping mechanism provided by the present invention comprises a support plate 1, a driving assembly and at least two groups of clamping jaws, wherein the multiple groups are uniformly arranged on the support plate 1, and the multiple groups of clamping jaws clamp different workpieces under the drive of the driving assembly, thereby improving the functional and structural integration of the multiple groups of clamping jaws, so that during use, different clamping jaws can be directly driven by the driving assembly, and the clamping functions of the multiple groups can be realized respectively and sequentially, without the need to switch between the two types of clamping jaws through an additional quick-change interface and then continue to use them, thereby saving the time that the clamping mechanism occupies the loading station and improving the production efficiency of the clamping mechanism.

[0034] It should be noted that, in the description of the present disclosure, the clamping mechanism is stationary on the ground, and up and down are the up and down directions of the clamping mechanism, which can also be called the height direction, and left and right are the horizontal directions of the clamping mechanism, which can also be called the width direction. The support plate 1 of the clamping mechanism has an upper side and a lower side relatively arranged along the height direction, which can also be called the upper surface and the lower surface, or the top surface and the bottom surface. The support plate 1 can be rectangular or square, and the support plate 1 has two ends relatively arranged along the width direction (also called the left and right direction), and the support plate 1 also has two ends relatively arranged along the length direction (also called the front and back direction). The directional words disclosed in the present disclosure are only for the convenience of description, and are not used to limit the specific direction of the clamping mechanism disclosed in the present disclosure.

[0035] In some embodiments, the clamp includes at least a first clamp 2 and a second clamp 3, and the first clamp 2 is arranged on the support plate 1 for clamping the first workpiece. The second clamp 3 is arranged on the support plate 1 for clamping the second workpiece. The driving assembly is respectively connected to the first clamp 2 and the second clamp 3 for driving the first clamp 2 to clamp the first workpiece, and driving the second clamp 3 to clamp the second workpiece. The first clamp 2 and the second clamp 3 are arranged on the same side of the support plate 1, that is, the first clamp 2 and the second clamp 3 are both arranged at the bottom surface (lower side) of the support plate 1, or one of the first clamp 2 and the second clamp 3 is arranged at the end position of the support plate 1.

[0036] It should be noted that, in the above-mentioned two settings of the first clamping jaw 2 and the second clamping jaw 3, during actual use, the first clamping jaw 2 can be set at both ends of the support plate 1 in the left-right direction, or set in the circumference of the support plate 1, and the second clamping jaw 3 can be set on the lower side of the support plate 1, and can be relatively set at a position close to the middle of the support plate 1, that is, the first clamping jaw 2 and the second clamping jaw 3 are staggered to prevent the two groups of clamping jaws from affecting each other's normal clamping function.

[0037] In some embodiments, reference Figure 1 and Figure 2 As shown, the number of the first clamping jaws 2 is at least two and they are respectively located at two opposite ends of the support plate 1 in the left and right directions. The number of the first clamping jaws 2 can be 2, or 4, 6, etc. The driving assembly includes a first driving member 41, and the first driving member 41 is two and is respectively located at two ends of the support plate 1 corresponding to the first clamping jaw 2. The first driving member 41 at each end is used to drive all the first clamping jaws 2 at the corresponding end to clamp the first workpiece. The driving mode of the first driving member 41 can be hydraulic drive, pneumatic drive, electrical drive and mechanical drive, etc., and the first driving member 41 can adopt a cylinder. Each first driving member 41 is driven and connected to the first clamping jaw 2 at the corresponding end to clamp the first workpiece. Controlling the first clamping jaw 2 by the cylinder is conducive to improving the degree of automation of the use of the clamping mechanism and adjusting the clamping force of the first clamping jaw 2, thereby improving the clamping effect.

[0038] Furthermore, the clamping mechanism also includes two first clamping portions 51, which are respectively located at the two ends of the support plate 1 corresponding to the first clamping jaw 2, and the first clamping portion 51 is located on the bottom surface (lower side) of the support plate 1, corresponding to the first workpiece to be clamped. The first clamping portion 51 can be a rod-shaped structure, and the first clamping portion 51 has a resting plane extending away from the support plate 1 to rest on the first workpiece. The first workpiece is a tray, and can also be other plate-like structures. The first clamping jaw 2 is an L-shaped structure. Specifically, the clamping end of the first clamping jaw 2 is L-shaped, which is adapted to the edge of the first workpiece. The first clamping jaw 2 can only clamp one workpiece during a clamping process. When the clamping mechanism moves to the position of the first workpiece, and the first clamping portion 51 abuts against the top surface (upper side) of the first workpiece, the first driving member 41 drives the first clamping jaw 2 to move to the bottom of the first workpiece, and the L-shaped clamping end of the first clamping jaw 2 buckles the bottom surface (lower side) of the first workpiece, and the first clamping portion 51 abuts against the top surface (upper side) of the first workpiece to stably clamp the first workpiece for subsequent movement and loading. The cooperation between the first clamping jaw 2 and the first clamping portion 51 is conducive to ensuring the clamping force on the first workpiece, avoiding the different speeds of the first driving member 41 causing the first clamping jaws 2 to be unable to clamp the first workpiece at the same time, causing the first workpiece to be unevenly stressed and shifted, thereby ensuring the uniformity of the clamping force of the first clamping jaw 2 and the stability of the clamping, and avoiding the first workpiece from slipping out.

[0039] Specifically, the clamping mechanism includes two push rods 61 and two connecting rods 62. The two push rods 61 are respectively located at the two ends of the support plate 1 corresponding to the first clamping jaw 2, and the two connecting rods 62 are respectively located at the two ends of the support plate 1 corresponding to the first clamping jaw 2. In addition, one end of the push rod 61 is connected to the output end of the first driving member 41, and the other end is connected to the corresponding connecting rod 62. At least two first clamping jaws 2 are arranged on each connecting rod 62. For example, one first clamping jaw 2 can be respectively arranged at both ends of each connecting rod 62, and three first clamping jaws 2 can also be arranged on the connecting rod 62. In the specific clamping process, one end of the push rod 61 is hinged to the output end of the first driving member 41, and the other end is fixed to the connecting rod 62. The two ends of the support plate 1 are provided with a protruding seat 63, and the two ends of the connecting rod 62 are rotatably connected to the protruding seat 63 fixed to the support plate 1. In addition, the end of the first clamping jaw 2 away from the clamping end is fixed to the connecting rod 62. The first driving member 41 is a linear motor, and the output end of the first driving member 41 is arranged upward, so that the first driving member 41 is inclined, and the output end of the first driving member 41 pushes the push rod 61 in the direction away from the first driving member 41, and the lower end position of the push rod 61 remains unchanged, and the upper end changes position with the push of the output end, so that at this time, the connecting rod 62 only rotates in situ relative to the extension seat 62, and no displacement occurs. During the rotation of the connecting rod 62, the first clamping jaw 2 rotates downward accordingly, and the first clamping jaws 2 at both ends are relatively close to clamp the first workpiece, and relatively away from each other to put down the first workpiece. That is to say, under the driving action, the first clamping jaws 2 at both ends can swing in the direction of approaching each other relative to the direction of the support plate 1 to cooperate with the first clamping parts 51 at both ends to clamp the first workpiece, and the first clamping jaws 2 at both ends can swing in the direction of away from each other relative to the direction of the support plate 1 to put down the first workpiece.

[0040] In some embodiments, reference Figure 2 As shown, the number of the second clamping jaws 3 is at least two, and they are respectively located at two opposite ends of the support plate 1 in the front-to-back direction. The number of the second clamping jaws 3 can be 2, or 4, 6, etc. A clamping jaw base 31 is arranged between the second clamping jaw 3 and the support plate 1. The driving assembly includes at least two second driving members 42, which are located on the upper side of the support plate 1 away from the second clamping jaw 3, that is, the second driving member 42 is located on the upper surface (top surface) of the support plate 1, and the number and setting position of the second driving members 42 correspond to the second clamping jaw 3 one by one. The driving mode of the second driving member 42 can be hydraulic drive, pneumatic drive, electrical drive and mechanical drive, etc. The second driving member 42 is a linear driving member, and a cylinder can be used. The output end of each second driving member 42 is connected to the corresponding second clamping jaw 3 to drive the corresponding second clamping jaw 3 to extend in the direction away from the support plate 1, that is, the output end of the cylinder passes through the clamping jaw base 31 to drive the second clamping jaw 3 to extend downward to clamp the second workpiece. Controlling the second clamping jaw 3 by means of the air cylinder is beneficial to improving the degree of automation in the use of the clamping jaw mechanism and adjusting the clamping force of the second clamping jaw 3, thereby improving the clamping effect.

[0041] Further, the clamping mechanism further includes a guide portion 7, which is arranged in a one-to-one correspondence with the second clamping jaw 3. Specifically, the guide portion 7 can be a cylindrical structure, and the number and arrangement position of the guide portion 7 correspond to the second clamping jaw 3. The second clamping jaw 3 extends downward under the driving action of the second driving member 42, and the second clamping jaw 3 cooperates with the guide portion 7 along the extension direction during the extension process to ensure that the extension direction of the second clamping jaw 3 does not deviate, that is, to ensure that the second clamping jaw 3 extends in a straight line.

[0042] Furthermore, the clamping mechanism further includes two second clamping portions 52, which are respectively located at two ends of the support plate 1 corresponding to the second clamping jaw 3, and the second clamping portion 52 is located on the lower side (bottom surface) of the support plate 1, corresponding to the second workpiece to be clamped. The second clamping portion 52 can be a rod-shaped structure, and the second clamping portion 52 has a contact plane extending away from the support plate 1 to contact the second workpiece.

[0043] It should be noted that in actual application, different jaws correspond to different workpiece sizes, so there is a corresponding positional relationship between each set of different jaws. In some embodiments, the first workpiece is a pallet, and the second workpiece is another plate-like structure. In this case, the first jaw 2 and the second jaw 3 not only need to be staggered, but the second jaw 3 is also located on the inner side of the first jaw 2, so that the two sets of jaws can each clamp workpieces of corresponding sizes. In addition, each clamping process can only clamp one workpiece. In order to distinguish the clamping process of the clamping mechanism for different workpieces and facilitate the rapid clamping of the workpiece, the height of the first clamping portion 51 is higher than that of the second clamping portion 52. In addition, the first clamping portion 51 is located near the side edge of the support plate 1, and the second clamping portion 52 is located at a position of the support plate 1 away from the side edge relative to the first clamping portion 51, that is, the first clamping portion 51 is located outside the second clamping portion 52. Therefore, even if the first clamping portion 51 is higher than the second clamping portion 52, it will not cause the first clamping portion 51 to interfere with the second workpiece, making the second clamping portion 52 unable to abut against the second workpiece.

[0044] The second clamping jaw 3 is a hook-shaped structure. Specifically, the clamping end of the second clamping jaw 3 is hook-shaped, and the second clamping jaw 3 can rotate left and right to adapt to the edge of the second workpiece. The second clamping jaw 3 can only clamp one workpiece in one clamping process. When the clamping mechanism moves to the position of the second workpiece and the second clamping portion 52 abuts against the top surface (upper side) of the second workpiece, the second driving member 42 extends toward the lower side of the support plate 1, and the second driving member 42 can drive the second clamping jaw 3 to extend downward during the extension process. At this time, the clamping end of the second clamping jaw 3 rotates to the outside, that is, the clamping end of the second clamping jaw 3 will not interfere with the side of the second workpiece, so that the second clamping jaw 3 can be smoothly extended and moved to the bottom of the second workpiece. After the second clamping jaw 3 moves to the target position, the second clamping jaw 3 can be rotated so that the hook-shaped clamping end of the second clamping jaw 3 buckles the bottom surface (lower side) of the second workpiece. At this time, the second clamping portion 52 abuts against the top surface (upper side) of the second workpiece, so that under the joint pressure of the second clamping portion 52 and the hook-shaped clamping end of the second clamping jaw 3, the second workpiece can be stably clamped for subsequent movement and loading. After the second workpiece is transferred to the target position, when the second workpiece needs to be released, the second driving member 42 retracts toward the upper side close to the support plate 1, and the clamping end of the second clamping jaw 3 rotates to the outside so that the clamping end does not interfere with the side of the second workpiece. The second driving member 42 can drive the second clamping jaw 3 to reset during the retraction process, and the hook-shaped clamping end of the second clamping jaw 3 can be disengaged from the clamping of the second workpiece, and the clamping jaw mechanism moves upward, and the second clamping portion 52 is disengaged from the pressure on the second workpiece, thereby achieving the release of the second workpiece. The cooperation between the second clamping jaw 3 and the second clamping portion 52 is conducive to ensuring the clamping force on the second workpiece, avoiding the different speeds of the first driving member 41 causing the second clamping jaws 3 to be unable to clamp the second workpiece at the same time, causing the first workpiece to be unevenly stressed and shifted, thereby ensuring the uniformity of the clamping force of the second clamping jaw 3 and the stability of the clamping, and avoiding the second workpiece from slipping out.

[0045] It should be noted that the coordinated clamping of the two jaws and the two clamping parts in the above embodiment is only an exemplary setting method. In actual application, the clamping part may not be provided, and the first jaw 2 may be directly provided as a U-shaped structure to clamp the end of the first workpiece through the U-shaped first jaw 2; or, the second jaw 3 may be directly provided as a claw-shaped structure to grasp the end of the second workpiece through the claw-shaped second jaw 3, thereby realizing the clamping of different workpieces.

[0046] The driving members and the clamps in the above embodiments are all mechanically connected and driven, and there is no need to frequently switch between different types of clamps, so that the overall structure of the clamp mechanism is simple and reliable, and the failure rate during use is low. This can avoid the situation where when it is necessary to switch between different types of clamps and the output is high, the clamp mechanism fails due to excessive switching frequency, thereby affecting production efficiency.

[0047] In some embodiments, the clamping mechanism further includes a plurality of support portions 8, which are arranged on a side of the support plate 1 close to the second clamping jaw 3, that is, the support portion 8 is arranged on the lower side (bottom surface) of the support plate 1, and the number can be 2 or 4. The height of the support portion 8 can be flexibly set according to the support requirements of different types of second workpieces, as long as stable support for the second workpiece can be achieved, so that the clamping and loading process of the second workpiece is more stable. In actual application, a support component for supporting the first workpiece can also be provided.

[0048] In some embodiments, reference Figure 3 As shown, the clamping mechanism also includes a positioning portion, which is located on a side of the support plate 1 close to the second clamping jaw 3, that is, the positioning portion is located on the lower side of the support plate 1. Specifically, the positioning portion includes a first positioning pin 91 and a second positioning pin 92. The second workpiece is provided with a positioning hole that is plugged in and matched with the first positioning pin 91 and the second positioning pin 92. The first positioning pin 91 is circular, and the positioning hole that is plugged in and matched with it is a circular hole. The second positioning pin 92 is rhombus-shaped, and the positioning hole that is plugged in and matched with it is a rhombus-shaped hole. When the clamping mechanism moves to the position of the second workpiece, the first positioning pin 91 and the second positioning pin 92 are first plugged into the corresponding positioning holes on the second workpiece to preliminarily position the second workpiece to prevent it from shifting during the subsequent clamping process, and then the second driving member 42 drives the second clamping jaw 3 to clamp the second workpiece. In actual application, the positioning part may further include a third positioning pin, which is square. Correspondingly, a square positioning hole that is plugged into and cooperates with the third positioning pin may be provided on the first workpiece to pre-position the first workpiece to prevent it from shifting during the subsequent clamping process.

[0049] In some embodiments, reference Figure 1 and Figure 2 As shown, the clamp mechanism also includes a detection unit 10, which is arranged on the support plate 1, and the detection unit 10 is used to detect the positions of the first workpiece and the second workpiece. The detection unit 10 can be a sensor, for example, a camera can be used to accurately identify the positions of the first workpiece and the second workpiece by photographing the working environment, and after determining the specific position information of the workpiece, the clamp mechanism is moved to the workpiece grasping point, that is, the position of the workpiece, and the workpiece is pre-positioned by the positioning unit, and then the corresponding workpiece is clamped by the corresponding clamp for subsequent loading.

[0050] Other embodiments of the present disclosure also provide an automatic loading and unloading system, including a driving unit and a clamping mechanism as in any of the above embodiments, and a connecting portion 11 driven and connected to the driving unit is provided on the support plate 1. The automatic loading and unloading system may also be referred to as an automatic loading and unloading robot or a handling robot, and the driving unit may be the sixth axis of the manipulator in the automatic loading and unloading system, and the connecting portion may be composed of a flange or other structure, and the sixth axis is driven and connected to the connecting portion 11 to drive the clamping mechanism as a whole to move and load materials. The automatic loading and unloading system adopts a clamping mechanism, so that different clamps can be driven directly by a driving assembly during use, so that the clamping functions of the first clamping jaw 2 and the second clamping jaw 3 can be realized respectively in sequence, without having to switch between the two clamping jaws through an additional quick-change interface and then continue to use them, which saves the time that the clamping mechanism occupies the loading station and improves the production efficiency of the automatic loading and unloading system.
