[0043] The present application will be further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0044] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0047] This embodiment provides a clamp, such as Figures 1-8 As shown, the fixture includes a mounting member 10 and a clamping mechanism 20. Specifically, at least two clamping mechanisms 20 are provided, and the at least two clamping mechanisms 20 are spaced apart along the width direction of the mounting member 10. The clamping mechanism 20 includes a first driving member 21 and a clamping assembly 22. The mounting member 10 is connected to the top of the at least two clamping assemblies 22. The first driving member 21 is disposed on the clamping assembly 22 and can drive the at least two clamping assemblies 22 to move along the width direction of the mounting member 10. The clamping assembly 22 also includes a bracket 221, a second driving member 222, and a clamping plate assembly. The mounting member 10 is connected to the top of the bracket 221. The second driving member 222 and the clamping plate assembly are both disposed at the bottom of the bracket 221. The second driving member 222 can drive the clamping plate assembly to clamp the workpiece 100.

[0048] By arranging multiple clamping mechanisms 20 along the width direction of the mounting piece 10, the overall length of the clamp can be reduced, and the multiple clamping mechanisms 20 can be retracted towards the center of the mounting piece 10, which facilitates the placement of the workpiece 100 in the packaging box 200. In addition, the mounting piece 10 and the clamp group are arranged at the top end and the bottom of the support 221, respectively, which further reasonably utilizes the space and reduces the overall space occupation. At the same time, the clamp group can freely clamp the workpiece at the bottom of the support 221, which ensures the convenience of use.

[0049] It is worth noting that in the present embodiment, the workpiece 100 to be clamped is a stand-up bag, which contains a fluid inside. Normally, the stand-up bag can be placed vertically on a horizontal surface. In other embodiments, other types of products can also be clamped using this clamp, and the scope of use of the clamp is not limited in the present embodiment.

[0050] Further, to ensure that the clamp can smoothly clamp the stand-up bag, in the present embodiment, the clamp group is arranged in the vertical direction, and the clamping end of the clamp group has a guide slope. The height of the clamp group in the vertical direction is not less than the height of the workpiece 100. First, since multiple stand-up bags are normally placed vertically on a horizontal surface, arranging the clamp group in the vertical direction can facilitate the adhesion of the clamp group to the stand-up bag. Second, since the clamping end of the clamp group (i.e., the end away from the support 221) has a guide slope, the guide slope can enable the clamp group to smoothly insert into the gap of the multiple stand-up bags, thereby clamping the stand-up bags. Finally, since the height of the clamp group in the vertical direction is not less than the height of the workpiece 100, it can be ensured that the stand-up bag will not sway left and right during clamping, and when placed, the bottom end of the stand-up bag can be in horizontal contact with the bottom surface of the packaging box 200, thereby ensuring that multiple stand-up bags can be arranged vertically and neatly in the packaging box 200.

[0051] To simplify the overall structure of the clamp, as shown in Figure 1 and Figure 2 , the support 221 includes a support plate 2211 and a column 2212. The two ends of the support plate 2211 are provided with columns 2212, and a guide 224 is arranged between the two columns 2212. The second driving member 222 can drive the clamp group to slide along the axial direction of the guide 224. The first driving member 21 is arranged at the bottom end of the support plate 2211, and the second driving member 222 is arranged at the side of the column 2212 close to the support plate 2211.

[0052] As shown in Figure 1 and Figure 2As shown, the support plate 2211 is used to support the mounting member 10, while both ends of the support plate 2211 are used to connect the columns 2212, and the columns 2212 are arranged in the vertical direction, which can ensure that there is enough space between the bottom of the support plate 2211 and the columns 2212 to arrange other structures, so that the first driving member 21 can be arranged at the bottom of the support plate 2211, thereby avoiding occupying the space at the top end of the support plate 2211, and the guide member 224 can be arranged between the two columns 2212, so that the second driving member 222 drives the clamping plate group to slide along the axial direction of the guide member 224, which can ensure that the clamping plate group moves along the preset direction, thereby ensuring good clamping effect; in addition, the second driving member 222 is arranged on the side of the column 2212 close to the support plate 2211, which can further reduce the overall size. It should be pointed out here that the guide member 224 is arranged in parallel and at intervals along the Y-axis direction; such an arrangement can ensure the smoothness of the clamping plate group sliding along the guide member 224. In other embodiments, the number of guide members 224 can be adjusted according to actual needs, and the present embodiment is not limited otherwise.

[0053] In order to further simplify the overall structure, as shown in Figure 1 and Figure 2 The clamping assembly 22 further comprises a lead screw 223 connected between the two columns 2212 and arranged in parallel at the bottom end of the guide member 224, and the rotation of the lead screw 223 can drive the clamping plate group to slide along the axial direction (i.e. the X-axis direction) of the guide member 224 and clamp the workpiece 100; in addition, in order to ensure that the clamping plate group can be driven smoothly, the clamping mechanism 20 further comprises a synchronous assembly 23, which comprises a first synchronous wheel 231 and a second synchronous wheel 232, the first synchronous wheel 231 and the second synchronous wheel 232 are connected by a synchronous belt 233, and the output end of the second driving member 222 is in transmission connection with the first synchronous wheel 231, and the second synchronous wheel 232 is in transmission connection with one end of the lead screw 223, so that the second driving member 222 can drive the lead screw 223 to rotate.

[0054] It should be noted that the two ends of the lead screw 223 are respectively connected to the two columns 2212 through the rotary bearing 28, so that the lead screw 223 can rotate under the drive of the second driving member 222 and the synchronous assembly 23; in addition, as shown in Figure 2 A bearing pressing plate 29 is further arranged outside the rotary bearing 28, so as to ensure that the rotary bearing 28 will not fall off the outside of the column 2212 during use, thereby ensuring good use effect.

[0055] It is worth noting that the second driving member 222 is a rotary servo motor, and since the second driving member 222 is arranged on one side of the column 2212 close to the support plate 2211, the synchronous assembly 23 can be conveniently driven by the second driving member 222 to drive the lead screw 223 to rotate and in turn drive the clamp plate group to clamp the workpiece 100. In addition, it is worth noting that, as shown in Figure 1 , the synchronous assembly 23 is arranged on the side of the column 2212 away from the second driving member 222, which not only facilitates the transmission connection between the second driving member 222 and the first synchronous wheel 231, but also facilitates the connection between the second synchronous wheel 232 and the lead screw 223, thereby improving the convenience of use.

[0056] In addition, as shown in Figure 1 , in order to ensure that the synchronous assembly 23 has good transmission effect, as shown in Figure 1 , the synchronous assembly 23 further comprises a tensioning wheel 234, which is arranged between the first synchronous wheel 231 and the second synchronous wheel 232, and the tensioning wheel 234 is used for tensioning the synchronous belt 233. By arranging the tensioning wheel 234, it can be ensured that the synchronous belt 233 is always in a state of being stretched, thereby ensuring good transmission effect.

[0057] In addition, as shown in Figure 1 , the synchronous assembly 23 further comprises a protective cover 235, which covers the outside of the first synchronous wheel 231, the second synchronous wheel 232, the synchronous belt 233 and the tensioning wheel 234, thereby preventing the external environment from affecting the normal operation of the synchronous assembly 23, and also ensuring the safety of use.

[0058] In order to facilitate clamping the workpiece 100, as shown in Figure 2 , the guide member 224 of the clamping assembly 22 is axially spaced apart to arrange at least two clamp plate groups, each of which comprises a first clamp plate 225 and a second clamp plate 226, and at least two second clamp plates 226 are fixedly arranged on the guide member 224. At least two first clamp plates 225 are in transmission connection with the lead screw 223, and the lead screw 223 is configured to drive at least two first clamp plates 225 to move simultaneously towards the direction close to the second clamp plate 226 in each clamp plate group, so that the clamp plate group can clamp the workpiece 100. Such an arrangement can clamp the workpiece 100 by driving only the first clamp plate 225; in addition, since at least two clamp plate groups are arranged, the number of workpieces 100 clamped at one time can be increased, thereby improving the clamping efficiency.

[0059] It should be noted that, as shown in Figure 1 and Figure 2As shown, in the embodiment, the clamping assembly 22 is provided with two clamping plate groups. In other embodiments, the number of the clamping plate groups can be adjusted according to actual needs, which is not limited in the embodiment. It is further explained that, in the embodiment, the top end of the two first clamping plates 225 is provided with a linear bearing 24, and the first clamping plate 225 is slidably connected with the guide 224 through the linear bearing 24; the two second clamping plates 226 are fixed on the guide 224 through the linear bearing 24. In addition, the first clamping plate 225 is further provided with a screw sleeve 25, and the screw sleeve 25 is fixed on the first clamping plate 225 through a screw sleeve fixing member 26, that is, the first clamping plate 225 is drivingly connected with the screw thread of the lead screw 223 through the screw sleeve 25, so that the rotation of the lead screw 223 drives the first clamping plate 225 to move towards the second clamping plate 226, so as to clamp the workpiece 100.

[0060] It is further explained that, as shown in Figure 2 In the embodiment, the clamping assembly 22 has two clamping plate groups, so the lead screw 223 is a left-right rotating reverse tooth trapezoidal lead screw, that is, the two ends of the lead screw 223 are provided with screw threads with different rotation directions, and the two first clamping plates 225 are drivingly connected with the screw threads with different rotation directions, so that when the second driving member 222 drives the lead screw 223 to rotate in one direction through the synchronous assembly 23, the two first clamping plates 225 can move towards or away from the corresponding second clamping plate 226 at the same time due to the different setting directions of the screw threads, so as to ensure that the second driving member 222 can drive two clamping plate groups to clamp or release the workpiece 100 at the same time.

[0061] It is further explained that, as shown in Figure 1 and Figure 2 As shown, the first clamping plate 225 and the second clamping plate 226 are designed with clamping plate side walls 229 on both sides along the width direction (that is, the Y-axis direction) of the mounting member 10, and the end of the clamping plate side wall 229 away from the bracket 221 is provided with a guide inclined surface. As described above, the guide inclined surface can make the first clamping plate 225 and the second clamping plate 226 quickly inserted into the gap between the adjacent two stand-up bags, so as to facilitate clamping; in addition, since the inside of the stand-up bag is a fluid, when the first clamping plate 225 and the second clamping plate 226 clamp the stand-up bag, the stand-up bag will be extruded along the X-axis direction until it is completely extruded, and then it can be grabbed, and the clamping plate side walls 229 on both sides of the first clamping plate 225 and the second clamping plate 226 can ensure that the stand-up bag does not move along the Y-axis direction when it is extruded along the X-axis direction, so as to ensure good clamping effect.

[0062] As shown in Figure 1 and Figure 2As shown, a positioning piece 227 is arranged between the first clamping plate 225 and the second clamping plate 226 in each clamping plate group, and the positioning piece 227 is used for positioning the distance between the first clamping plate 225 and the second clamping plate 226 in each clamping plate group. The positioning piece 227 is fixed to the top end of the linear bearing 24 of the first clamping plate 225 through a fixing portion 2272, the top end of the linear bearing 24 of the second clamping plate 226 is provided with a sliding portion 2273, a guide groove 2271 is arranged between the fixing portion 2272 and the sliding portion 2273 on the positioning piece 227, and the sliding end of the sliding portion 2273 extends into the guide groove 2271. When the first clamping plate 225 moves towards the second clamping plate 226, the sliding portion 2273 can slide in the guide groove 2271, so as to ensure the clamping effect. After use, the sliding portion 2273 can be directly moved to the end of the guide groove 2271 away from the fixing portion 2272. Since the length of each guide groove 2271 is the same, the distance between the first clamping plate 225 and the second clamping plate 226 in each clamping plate group can be ensured to be the same, and thus a good use effect can be ensured.

[0063] As shown in the figure, Figure 1 The bottom of the mounting piece 10 is designed with a sliding block 11, and the top end of the clamping assembly 22 is designed with a sliding groove 228. The sliding block 11 and the sliding groove 228 are in sliding connection. After each clamping mechanism 20 clamps the workpiece 100, the plurality of clamping mechanisms 20 need to be retracted to the center position of the mounting piece 10, so that the clamping mechanism 20 can clamp the workpiece 100 to extend into the packaging box. Therefore, by making the clamping assembly 22 and the mounting piece 10 in sliding connection, the smoothness in the process can be ensured, thereby improving the boxing efficiency. It should be noted that in the embodiment, the clamp is provided with two clamping mechanisms 20. In other embodiments, the number of clamping mechanisms 20 can be selected according to the opening width of the packaging box 200, and the embodiment is not limited in other ways.

[0064] It should be further explained that in the embodiment, the first driving piece 21 is a gas cylinder, the extending end of the gas cylinder is connected with one end of the connecting plate 27, and the other end of the connecting plate 27 is connected with the mounting piece 10. Since the gas cylinder is arranged at the bottom end of the support 221, when the extending end of the gas cylinder extends or retracts, the clamping assembly 22 can be driven to move along the Y-axis direction, that is, the two clamping assemblies 22 can be moved towards the center of the mounting piece 10 or moved towards the outer periphery of the mounting piece 10, so as to ensure that the workpiece 100 can be smoothly packed.

[0065] As shown in the figure, Figure 1As shown, a connecting piece 30 is arranged at the top end of the mounting piece 10, and the connecting piece 30 facilitates the connection of the clamp to other driving structures, thereby ensuring that the clamp can be used smoothly. It should be noted that in the present embodiment, the connecting piece 30 is a flange plate, which has the advantages of convenient welding and processing, low cost, and the ability to withstand large tensile strength. In other embodiments, other structures such as connecting bolts are arranged, as long as they can ensure that the clamp is stably connected to other structures, and no other limitations are made in the present embodiment.

[0066] The present embodiment also provides a clamping and boxing method based on the clamp described above. The operation steps of the method are described below in combination with Figures 1-8 the description of the clamp.

[0067] S100, the second driving piece 222 drives the first clamping plate 225 of the clamping plate group to move in the axial direction of the guide piece 224, and the first clamping plate 225 and the second clamping plate 226 in the same clamping plate group together complete the clamping of the workpiece 100;

[0068] S200, the first driving piece 21 drives the at least two clamping assemblies 22 to move in the width direction (i.e., the Y-axis direction) of the mounting piece 10, and the at least two clamping assemblies 22 are gathered towards the center of the mounting piece 10, so that the clamping plate group can directly extend into the packaging box 200;

[0069] S300, the clamp is connected to other driving structures through the connecting piece 30, the driving mechanism drives the clamp, and the two clamping assemblies 22 extend into the packaging box 200, and the second driving piece 222 drives the clamping plate group to release the workpiece 100, so that the workpiece 100 can stand upright in the packaging box 200;

[0070] S400, the clamp is driven to make the two clamping plate groups separate from the packaging box 200, and after separation, the first clamping plate 225 and the second clamping plate 226 are reset to the original state, so as to facilitate the next round of clamping and boxing.

[0071] In summary, the clamp provided by the present embodiment has the advantages of simple and compact structure, low cost, and convenient operation, and the application of the method can also improve the boxing efficiency.

[0072] Obviously, the above embodiments of the present application are only examples for clear description of the present application, and are not limitations on the embodiments of the present application. Those skilled in the art can make various obvious changes, readjustments and substitutions without departing from the scope of the present application. It is not necessary or possible to exhaust all embodiments here.
