[0041] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] The following combination Figure 1-Figure 5 , the clamping jaws provided by the utility model embodiment are described in detail through specific embodiments and application scenarios.

[0043] like Figure 1 、 Figure 2 and Figure 4 As shown, the embodiment of the present utility model provides a clamping jaw 1, comprising: a driving assembly 11, a mounting seat 14 and a clamping assembly 12;

[0044] The driving assembly 11 and the clamping assembly 12 are respectively arranged on the mounting seat 14; the clamping assembly 12 includes a first clamping member 121, a second clamping member 122, a third clamping member 123 and a fourth clamping member 124;

[0045] The second clamping member 122, the third clamping member 123, and the fourth clamping member 124 are rotatably mounted on the mounting base 14 and are all configured to be in transmission connection with the driving assembly 11; the driving assembly 11 is used to drive the second clamping member 122, the third clamping member 123, and the fourth clamping member 124 to switch between an open state and a closed state;

[0046] Among them, a clamping interval for clamping a single row of target packages 10 is formed between the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124; the first clamping member 121 and the third clamping member 123 are arranged opposite to each other along the width direction of the mounting seat 14 to clamp the opposite sides of the single row of target packages 10 along the width direction; the second clamping member 122 and the fourth clamping member 124 are arranged opposite to each other along the length direction of the mounting seat 14 to clamp the opposite sides of the single row of target packages 10 along the length direction.

[0047] It is understandable that the target package 10 can be a Truensu package with a dream cover, and multiple Truensu packages are arranged in sequence along the length direction of the mounting seat 14, and the dream covers of each Truensu package are set to the same direction, thereby forming a Figure 4 A single row of target packages 10 is shown.

[0048] like Figure 1 and Figure 2As shown, at least part of the driving assembly 11 is arranged on the upper side of the mounting seat 14 along the thickness direction, and the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 are arranged on the lower side of the mounting seat 14 along the thickness direction. The first clamping member 121 can be configured to extend along the length direction of the mounting seat 14 and be fixedly arranged at the front side along the width direction of the mounting seat 14, so as to abut against the front side of the single-row target package 10 along the width direction; the second clamping member 122 can be configured to extend along the width direction of the mounting seat 14 and be rotatably arranged at the left side along the length direction of the mounting seat 14, so as to abut against the left side of the single-row target package 10 along the length direction; the third clamping member 123 can be configured to extend along the length direction of the mounting seat 14 and be rotatably arranged at the front side along the width direction of the mounting seat 14. The rear side in the width direction is used to abut against the rear side of the single-row target package 10 along the width direction; the fourth clamping member 124 can be configured to extend along the width direction of the mounting seat 14, and can be rotatably set on the right side along the length direction of the mounting seat 14, so as to abut against the right side of the single-row target package 10 along the length direction. This design can form a clamping interval for clamping the single-row target package 10 based on the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124, and can reliably clamp the single-row target package 10.

[0049] In actual application, the driving component 11 includes a driving part and a transmission part. The driving part can control the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 to move synchronously relative to the first clamping member 121 through the transmission part. For example, the driving component 11 can drive the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 to rotate toward the side close to the target package 10. At this time, each clamping member is close to the first clamping member 121 and is in a retracted state; accordingly, the driving component 11 can also drive the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 to rotate toward the side away from the target package 10. At this time, each clamping member is away from the first clamping member 121 and is in an open state.

[0050] Of course, the driving assembly 11 can also include two sets of driving parts, one set of driving parts is used to drive the second clamping member 122 and the fourth clamping member 124 to move synchronously, and the other set of driving parts drives the third clamping member 123 to move alone, as long as the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 can be driven to switch between the open state and the retracted state.

[0051] When the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 are in the open state, the clamping interval formed by the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 is relatively large, for example, the clamping interval is larger than the three-dimensional space corresponding to the single-row target package 10. At this time, the clamping assembly 12 cannot clamp the single-row target package 10; when the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 are in the retracted state, the clamping interval formed by the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 is adapted to the three-dimensional space corresponding to the single-row target package 10. At this time, the clamping assembly 12 can clamp the single-row target package 10.

[0052] The clamping jaw 1 shown in the present invention is provided with a driving assembly 11 and a clamping assembly 12 based on a mounting seat 14. The first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 of the clamping assembly 12 form a clamping interval for clamping a single row of target packages 10. When the driving assembly 11 drives the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 to be in a retracted state, the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 are in a retracted state. The second clamping member 122, the third clamping member 123 and the fourth clamping member 124 cooperate with each other to clamp the peripheral wall of the single-row target package 10 in four directions, thereby preventing the target package 10 from falling during the clamping process. When the driving component 11 drives the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 to be in the open state, the single-row target package 10 is released so that the single-row target package 10 can be loaded into the box under the action of its own gravity.

[0053] As can be seen from the above, the clamping jaw 1 shown in the present invention has a simple structure and can reliably clamp milk bags placed in a single row, which helps to improve the packing efficiency of the milk bags.

[0054] In some embodiments, as Figure 1 、 Figure 3 and Figure 4 As shown, the driving assembly 11 includes a first telescopic driving member 111, an adapter seat 112, a first connecting rod 113, a second connecting rod 114 and a third connecting rod 115;

[0055] The first telescopic driving member 111 is provided on the mounting base 14 and is connected to the adapter 112 to drive the adapter 112 to reciprocate along the thickness direction of the mounting base 14;

[0056] One end of the first connecting rod 113 is rotatably connected to the adapter seat 112, and the other end is rotatably connected to the second clamping member 122; one end of the second connecting rod 114 is rotatably connected to the adapter seat 112, and the other end is rotatably connected to the third clamping member 123; one end of the third connecting rod 115 is rotatably connected to the adapter seat 112, and the other end is rotatably connected to the fourth clamping member 124.

[0057] It is understandable that the first telescopic driving member 111 can be a cylinder or an electric push rod, and the telescopic end of the first telescopic driving member 111 is connected to the adapter 112, and the adapter 112 is provided on the side of the mounting base 14 facing the target package 10.

[0058] The first telescopic driving member 111 can drive the adapter 112 to reciprocate between a first position close to the mounting seat 14 and a second position away from the mounting seat 14; in the process of the adapter 112 moving from the second position to the first position, the adapter 112 drives the second clamping member 122 to rotate toward the side close to the target package 10 through the first connecting rod 113, drives the third clamping member 123 to rotate toward the side close to the target package 10 through the second connecting rod 114, and drives the fourth clamping member 124 to rotate toward the side close to the target package 10 through the third connecting rod 115, so as to clamp a single row of target packages 10 based on the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124.

[0059] Accordingly, in the process of the adapter 112 moving from the first position to the second position, the adapter 112 drives the second clamping member 122 to rotate toward the side away from the target package 10 through the first connecting rod 113, drives the third clamping member 123 to rotate toward the side away from the target package 10 through the second connecting rod 114, and drives the fourth clamping member 124 to rotate toward the side away from the target package 10 through the third connecting rod 115, so as to release the single row of target packages 10.

[0060] In some embodiments, as Figure 1 and Figure 2 As shown, the clamping jaw 1 further includes: a guide assembly 13 , which is provided between the mounting seat 14 and the adapter seat 112 and is used to guide the adapter seat 112 to move along the thickness direction of the mounting seat 14 .

[0061] It is understandable that the guide assembly 13 is used to ensure the stability of the adapter 112 moving relative to the mounting seat 14 along the thickness direction. The guide assembly 13 may include multiple guide units, each of which is used to guide the adapter 112 to move along the thickness direction of the mounting seat 14.

[0062] In some examples, the guide assembly 13 includes a guide block and a guide groove. The guide groove is provided on the mounting seat 14 and is configured to extend along the thickness direction of the mounting seat 14. The guide block is provided on the adapter seat 112 and is slidably provided in the guide groove along the thickness direction.

[0063] Some examples, such as Figure 2 and Figure 4 As shown, the guide assembly 13 includes a guide rod 131 and a guide sleeve 132; the guide sleeve 132 is arranged on the mounting seat 14; the guide rod 131 extends along the thickness direction of the mounting seat 14, one end of the guide rod 131 is connected to the adapter seat 112, and the other end is passed through the guide sleeve 132.

[0064] Specifically, the guide sleeve 132 is arranged on the upper side of the mounting seat 14 along the thickness direction, the adapter seat 112 and the clamping assembly 12 are both arranged on the lower side of the mounting seat 14 along the thickness direction, the lower end of the guide rod 131 is connected to the adapter seat 112, the middle part of the guide rod 131 is passed through the mounting seat 14, and the upper end of the guide rod 131 is passed through the guide sleeve 132.

[0065] Furthermore, an adapter frame is provided on the upper side of the mounting seat 14, and the adapter frame is configured to be connected to a transfer mechanism. For example, the transfer mechanism can be a multi-degree-of-freedom robot arm such as a three-axis robot arm, a six-axis robot arm, etc. After the upper end of the guide rod 131 extends out of the guide sleeve 132, it can also be configured to be passed through the guide hole on the adapter frame.

[0066] In some embodiments, as Figure 1 and Figure 2 As shown, at least one of the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 includes a linkage arm 1241 and a first clamping plate 1242; specifically, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 can be configured with a similar structure including a linkage arm 1241 and a first clamping plate 1242, as shown in FIG. Figure 3 As shown, taking the fourth clamping member 124 as an example, the driving component 11 is rotatably connected to the linkage arm 1241 of the fourth clamping member 124; the first end of the linkage arm 1241 is rotatably connected to the mounting seat 14, and the second end of the linkage arm 1241 is connected to the first clamping plate 1242 of the fourth clamping member 124, and the first clamping plate 1242 is used to clamp the target package 10.

[0067] It can be understood that when clamping the target package 10, the driving component 11 drives the linkage arm 1241 to rotate relative to the mounting seat 14 toward the side close to the target package 10, and the linkage arm 1241 drives the first clamping plate 1242 to swing toward the side close to the target package 10 until the first clamping plate 1242 abuts against the side of the target package 10, so that the first clamping member 121, the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 cooperate with each other to clamp a single row of target packages 10.

[0068] When the target package 10 is packed, the driving component 11 drives the linkage arm 1241 to rotate relative to the mounting seat 14 toward the side away from the target package 10, and the linkage arm 1241 drives the first clamping plate 1242 to swing toward the side away from the target package 10 until the first clamping plate 1242 is separated from the side of the target package 10. Then, the single row of target packages 10 will automatically fall into the box under the action of their own gravity.

[0069] Among them, the length of the first clamping plate 1242 of the third clamping member 123 extending along the length direction is the first length, and the length of the first clamping member 121 extending along the length direction is correspondingly set to the first length; the lengths of the first clamping plates 1242 of the second clamping member 122 and the fourth clamping member 124 extending along the width direction are the same, and are both the second length, and the first length is greater than the second length.

[0070] In some embodiments, as Figure 1 and Figure 5 As shown, the linkage arm 1241 includes a first arm section 12411 and a second arm section 12412; the second arm section 12412 is bent relative to the first arm section 12411 and is located on the side of the first arm section 12411 away from the target package 10;

[0071] One end of the first arm section 12411 away from the second arm section 12412 is rotatably connected to the mounting seat 14 , and one end of the second arm section 12412 away from the first arm section 12411 is connected to the first clamping plate 1242 .

[0072] Specifically, since the driving component 11 is rotatably connected to the linkage arm 1241, by bending the linkage arm 1241, it is convenient to drive the first clamping plate 1242 to flip at a large angle through the linkage arm 1241, which not only ensures the sensitivity of the driving component 11, but also improves the clamping ability of the clamping component 12.

[0073] like Figure 5As shown, the angle formed by the second boom section 12412 relative to the first boom section 12411 is β, and the value range of β can be 90º to 150º, for example, β can be specifically 90º, 100º, 120º, 135º, 140º or 150º.

[0074] In some embodiments, as Figure 3 As shown, a first flexible anti-slip layer 1243 is provided on a side of the first clamping plate 1242 facing the target package 10 . The first flexible anti-slip layer 1243 is configured to contact the surface of the target package 10 .

[0075] It is understandable that when the target package 10 is clamped, the first flexible anti-slip layer 1243 maintains flexible contact with the surface of the target package 10, which can prevent the first clamping plate 1242 from rigidly contacting the target package 10 and causing clamping damage to the target package 10, and when the first flexible anti-slip layer 1243 contacts the surface of the target package 10, it can ensure the contact friction between the contact surfaces of the two, thereby preventing the target package 10 from falling during the clamping process.

[0076] Optionally, the first flexible anti-slip layer 1243 can be an anti-slip rubber pad, for example, the anti-slip rubber pad has a pad body, the first side of the pad body is bonded to the first clamping plate 1242, and the second side of the pad body is configured to contact the side of the target package 10; wherein, the second side of the pad body is provided with uneven anti-slip stripes, and the pad body enhances the contact friction between the pad body and the target package 10 based on the anti-slip stripes.

[0077] In some embodiments, as Figure 3 and Figure 5 As shown, the first clamping plate 1242 includes a clamping body 12421 and a folding edge 12422; the second end of the linkage arm 1241 is connected to the clamping body 12421; the folding edge 12422 is bent relative to the clamping body 12421 and is located on the side of the clamping body 12421 away from the target package 10;

[0078] Wherein, on the side of the first clamping plate 1242 facing the target bag 10 , a smooth transition surface is formed at the connection between the clamping body 12421 and the folding edge 12422 .

[0079] It is understandable that since the first clamping plate 1242 is clamped on the side of the target package 10 in a flipped manner, by providing a folding edge 12422 on the lower side of the first clamping plate 1242, during the process of clamping the target package 10, the lower edge of the first clamping plate 1242 will not directly contact the side of the target package 10, but the folding edge 12422 will maintain surface contact with the side of the target package 10. This design not only ensures the effective contact area of ​​the first clamping plate 1242 on the target package 10, but also prevents clamping damage to the target package 10 during the clamping process.

[0080] like Figure 5 As shown, the angle formed by the second boom section 12412 relative to the first boom section 12411 is α, and the value range of α can be 145º to 175º, for example, α can be specifically 145º, 150º, 155º, 160º, 165º, 170º or 175º.

[0081] In some embodiments, as Figure 1 and Figure 2 As shown, the clamping jaw 1 further includes: a second telescopic driving member 15 , which is disposed on the mounting seat 14 and connected to the first clamping member 121 to drive the first clamping member 121 to move along the width direction of the mounting seat 14 .

[0082] It can be understood that before clamping the single-row target package 10, not only is the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 driven to flip toward the side away from the target package 10 by the driving component 11, but the first clamping member 121 is also driven by the second telescopic driving member 15 to move along the width direction toward the side away from the target package 10, so that the clamping members corresponding to the clamping component 12 are dispersed. At this time, the clamping interval corresponding to the clamping component 12 reaches a sufficiently large coverage range.

[0083] When clamping a single row of target packages 10, not only is the driving component 11 used to drive the second clamping member 122, the third clamping member 123 and the fourth clamping member 124 to flip toward the side close to the target package 10, but the second telescopic driving member 15 is also used to drive the first clamping member 121 to move along the width direction toward the side close to and away from the target package 10, so that the clamping members corresponding to the clamping component 12 are retracted. At this time, the clamping interval corresponding to the clamping component 12 is adapted to the three-dimensional space corresponding to the single row of target packages 10, which facilitates the clamping component 12 to complete the clamping of the single row of target packages 10.

[0084] The second telescopic drive member 15 can be a cylinder or an electric push rod known in the art. The second telescopic drive member 15 is arranged on the side of the first clamping member 121 facing the third clamping member 123. The second telescopic drive member 15 is configured to extend along the width direction.

[0085] In some embodiments, as Figure 3 As shown, the first clamping member 121 includes a second clamping plate 1211 and a second flexible anti-slip layer 1212; the second clamping plate 1211 is arranged parallel to the plane in which the length direction and thickness direction of the mounting seat 14 are located, and the second flexible anti-slip layer 1212 is arranged on the side of the second clamping plate 1211 facing the target package 10, and the second flexible anti-slip layer 1212 is configured to contact the surface of the target package 10.

[0086] It is understandable that since the first clamping member 121 contacts or separates from the side of the target package 10 along the width direction, the second clamping plate 1211 is designed to be plate-shaped, which can ensure the effective contact area between the second clamping plate 1211 and the side of the target package 10, thereby ensuring the reliability of clamping the target package 10.

[0087] The second flexible anti-slip layer 1212 can adopt a structure similar to the first flexible anti-slip layer 1243. For example, the second flexible anti-slip layer 1212 adopts an anti-slip rubber pad. During the clamping process of the target package 10, this design not only prevents clamping damage to the target package 10, but also ensures the contact friction between the first clamping member 121 and the target package 10, preventing the target package 10 from falling during the clamping process.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
