[0027] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0028] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference below Figures 1 to 4 The material clamping mechanism of the first aspect of the utility model is described in detail.

[0032] It should be noted that when the clamping mechanism of the present application is working, it is not only necessary to clamp the fixture, but also to clamp the cobalt needle.

[0033] In order to enable the clamping mechanism of the present application to have the functions of clamping the cobalt needle and the clamping fixture at the same time, in some embodiments of the present utility model, reference Figure 1 and Figure 3 The clamping mechanism includes a mounting frame 100, a first clamping assembly 200 and a second clamping assembly 300; the first clamping assembly 200 and the second clamping assembly 300 are both arranged on the mounting frame 100, and the first clamping assembly 200 is used to clamp the cobalt needle, and the second clamping assembly 300 is used to clamp the fixture.

[0034] It is understandable that, since the first clamping assembly 200 and the second clamping assembly 300 are simultaneously provided on the mounting frame 100, when the clamping mechanism of this embodiment needs to clamp the cobalt needle, the first clamping assembly 200 can be used to clamp the cobalt needle, and when the clamping mechanism of this embodiment needs to clamp the fixture, the second clamping assembly 300 can be used to clamp the fixture. The provision of the first clamping assembly 200 and the second clamping assembly 300 enables the clamping mechanism of this embodiment to simultaneously have the functions of clamping the cobalt needle and clamping the fixture. Accordingly, the handling device including the clamping mechanism of this embodiment can simultaneously have the functions of carrying the cobalt needle and carrying the fixture. There is no need to provide a plurality of manipulators for carrying the cobalt needle and the fixture in the handling device, thereby simplifying the overall structure of the handling device.

[0035] It should be noted that, during the operation of the clamping mechanism of the present application, if the clamping mechanism only grabs a single cobalt needle at a time, this will undoubtedly greatly limit the working efficiency of the clamping mechanism of the present application.

[0036] In order to improve the working efficiency of the clamping mechanism of the present application, in a further embodiment of the present utility model, reference is made to Figure 1 The first clamping assembly 200 includes a driving structure 210, a first clamping jaw structure 220 and a second clamping jaw structure 230. The first clamping jaw structure 220 includes a first mounting member 222 and a plurality of first clamping jaws 221. The plurality of first clamping jaws 221 are arranged on the first mounting member 222 at intervals along the first direction. The second clamping jaw structure 230 includes a second mounting member 232 and a plurality of second clamping jaws 231. The second clamping jaws 231 are arranged on the second mounting member 232 at intervals along the first direction. The first clamping jaw 221 and the second clamping jaw 231 are arranged in a one-to-one correspondence, and a cobalt needle clamping area is formed between the corresponding first clamping jaw 221 and the second clamping jaw 231. The driving structure 210 is connected to at least one of the first mounting member 222 and the second mounting member 232, and is used to drive the first mounting member 222 and the second mounting member 232 to move closer to or away from each other.

[0037] It can be understood that since the first clamping assembly 200 includes multiple groups of corresponding first jaws 221 and second jaws 231, when the first clamping assembly 200 clamps a cobalt needle, each group of corresponding first jaws 221 and second jaws 231 can cooperate to complete the clamping of a cobalt needle, so that the first clamping assembly 200 in this embodiment can clamp multiple cobalt needles at a time, thereby improving the working efficiency of the clamping mechanism of this embodiment.

[0038] It should be noted that the circumference of the cobalt needle is a curved surface.

[0039] In order to enable the first clamping jaw 221 and the second clamping jaw 231 to clamp the cobalt needle more stably, in a further embodiment of the present invention, Figure 2 and Figure 4 A first clamping groove 221c and a second clamping groove 231c adapted to the cobalt needle are respectively provided on the adjacent sides of the first clamping jaw 221 and the second clamping jaw 231, and the first clamping groove 221c and the second clamping groove 231c are both extended along the second direction.

[0040] It can be understood that by providing a first clamping groove 221c on the first clamping jaw 221 and a second clamping groove 231c on the second clamping jaw 231, when the first clamping jaw 221 cooperates with the second clamping jaw 231 to clamp the cobalt needle, the circumferential surface of the cobalt needle can be respectively fitted with the groove wall of the first clamping groove 221c and the groove wall of the second clamping groove 231c, thereby increasing the contact area between the cobalt needle and the first clamping jaw 221, and also increasing the contact area between the cobalt needle and the second clamping jaw 231, so that the first clamping jaw 221 can cooperate with the second clamping jaw 231 to clamp the cobalt needle more stably.

[0041] Specifically, the first clamping groove 221c and the second clamping groove 231c are both arc-shaped grooves.

[0042] It can be understood that the circumferential surface of the cobalt needle is arc-shaped. By setting the first clamping groove 221c and the second clamping groove 231c as arc-shaped grooves, when the first clamping groove 221c and the second clamping groove 231c cooperate to clamp the cobalt needle, the groove walls of the first clamping groove 221c and the second clamping groove 231c can fully fit the circumferential surface of the cobalt needle, so as to improve the stability of the first clamping assembly 200 in clamping the cobalt needle.

[0043] It can be understood that when the first clamping groove 221c and the second clamping groove 231c are both arc-shaped grooves, the groove surface of the arc-shaped groove can be composed of a whole arc surface, and the groove surface of the arc-shaped groove can also be composed of multiple arc surfaces.

[0044] Optionally, without considering the stability of the first clamping assembly 200 in clamping the cobalt needle, in other embodiments of the present invention, the groove surfaces of the first clamping groove 221c and the second clamping groove 231c can both be composed of multiple planes, for example, the first clamping groove 221c and the second clamping groove 231c are both V-shaped grooves.

[0045] Optionally, without considering the stability of the first clamping assembly 200 in clamping the cobalt needle, in other embodiments of the present invention, the groove surfaces of the first clamping groove 221c and the second clamping groove 231c can also be composed of a plurality of planes and a plurality of arc surfaces. For example, along the width direction of the first clamping groove 221c, the groove surface of the first clamping groove 221c includes a first arc surface, a first plane, a second plane and a second arc surface in sequence. At this time, the specific structure of the second clamping groove 231c refers to the first clamping groove 221c.

[0046] In a specific embodiment of the present invention, the first direction is a vertical direction, and the second direction is a horizontal direction.

[0047] In a further embodiment of the present invention, in order to enable the first clamping jaw 221 to cooperate with the second clamping jaw 231 to clamp the cobalt needle more firmly, Figure 2 and Figure 4 The first clamping jaw 221 includes a first clamping portion 221b, and the second clamping jaw 231 includes a second clamping portion 231b. The first clamping portion 221b and the second clamping portion 231b are alternately arranged along the second direction. A first clamping groove 221c is formed on the first clamping portion 221b, and a second clamping groove 231c is formed on the second clamping portion 231b.

[0048] It can be understood that since the first clamping portion 221b and the second clamping portion 231b are alternately arranged along the second direction, and a first clamping groove 221c is formed on the first clamping portion 221b, and a second clamping groove 231c is formed on the second clamping portion 231b, and therefore, when the first clamping jaw 221 cooperates with the second clamping jaw 231 to clamp the cobalt needle, the cobalt needle can have more structures in a clamped state in the second direction, thereby reducing the radial deviation of the cobalt needle itself, so that the first clamping jaw 221 and the second clamping jaw 231 can clamp the cobalt needle more stably.

[0049] Specifically, in Figure 2 and Figure 4 In the embodiment, one first clamping portion 221b is provided, and two second clamping portions 231b are provided. When the first clamping assembly 200 clamps the cobalt needle, the first clamping portion 221b is inserted into the area between the two second clamping portions 231b.

[0050] It should be noted that the first clamping portions 221b and the second clamping portions 231b may be alternately arranged along the second direction, and the specific number of the first clamping portions 221b and the specific number of the second clamping portions 231b are not specifically limited herein.

[0051] It should be noted that, since the first clamping jaw structure 220 includes a plurality of first clamping jaws 221 extending along the first direction, and the second clamping jaw structure 230 includes a plurality of second clamping jaws 231 extending along the first direction, the first clamping assembly 200 can clamp a row of cobalt needles arranged along the first direction at a time; however, due to the influence of errors, it is difficult for the individual cobalt needles in a row of cobalt needles to be arranged neatly along the first direction, and the specifications of the individual cobalt needles in a row of cobalt needles also vary; in this case, it is difficult for the first clamping assembly 200 to stably clamp the individual cobalt needles.

[0052] Based on the above problems, in some embodiments of the present invention, reference Figure 2 and Figure 4 The first clamping jaw 221 also includes a first connecting portion 221a, which is connected to the first mounting member 222. The second clamping jaw 231 also includes a second connecting portion 231a, which is connected to the second mounting member 232. At least one of the first connecting portion 221a and the second connecting portion 231a is made of an elastic material that can undergo elastic deformation under the action of an external force. The first clamping portion 221b is connected to one end of the first connecting portion 221a close to the second clamping jaw 231, and the second clamping portion 231b is connected to one end of the second connecting portion 231a close to the first clamping jaw 221.

[0053] For example, when the first clamping assembly 200 clamps a row of cobalt needles arranged along the front-to-back direction, if there is a first cobalt needle in the row of cobalt needles that is offset from other cobalt needles in the left-right direction, at this time, the first clamping jaw 221 and the second clamping jaw 231 clamping the first cobalt needle can be deformed in the left-to-right direction to collectively shift to the left or right to adapt to the shift of the first cobalt needle relative to other cobalt needles in the left or right direction.

[0054] For example, when the first clamping assembly 200 clamps a row of cobalt needles arranged along the front-to-back direction, if there is a second cobalt needle in this row of cobalt needles whose specifications are different from those of other cobalt needles, at this time, the first clamping jaw 221 and the second clamping jaw 231 clamping the second cobalt needle can be deformed in the left-right direction to get closer to or farther away from each other, so as to adapt to the second cobalt needle being smaller or larger in specifications than other cobalt needles.

[0055] Specifically, the first connection portion 221a and the second connection portion 231a are both made of an elastic material that can be elastically deformed under the action of an external force.

[0056] Optionally, without considering the clamping effect of the first clamping assembly 200 on the cobalt needle, the first connecting portion 221a or the second connecting portion 231a is made of an elastic material that can be elastically deformed under the action of an external force.

[0057] It should be noted that, since the first clamping assembly 200 can clamp multiple cobalt needles arranged along the first direction, in order for the first clamping assembly 200 to stably clamp each cobalt needle, the multiple cobalt needles clamped by the first clamping assembly 200 need to be able to be evenly subjected to the clamping force applied by the first clamping assembly 200.

[0058] Based on the above reasons, in some embodiments of the present invention, reference Figure 1 The driving structure 210 includes a plurality of first drivers 211 distributed side by side along a first direction. The first driver 211 includes a first driving end and a second driving end. The first driving end is connected to a first mounting member 222 of the first clamping structure 220, and the second driving end is connected to a second mounting member 232 of the second clamping structure 230. The first driver 211 can drive the first mounting member 222 and the second mounting member 232 to move closer to or away from each other through the first driving end and the second driving end.

[0059] It can be understood that the arrangement of the plurality of first drivers 211 distributed along the first direction enables each cobalt needle clamped by the first clamping assembly 200 to be evenly subjected to the clamping force applied by the first clamping assembly 200 .

[0060] Specifically, in Figure 1 In the embodiment, it is taken as an example that the driving structure 210 includes two first drivers 211 distributed along the first direction.

[0061] In some embodiments of the present invention, in order to enable the second clamping assembly 300 to clamp multiple fixtures at the same time, the second clamping assembly 300 includes a plurality of clamping structures 310 distributed in parallel along the third direction, and each clamping structure 310 can clamp a fixture.

[0062] exist Figure 1 In the embodiment, it is taken as an example that the second clamping assembly 300 includes two clamping structures 310 distributed in parallel along the third direction.

[0063] It should be noted that, in a specific embodiment of the present invention, the third direction is parallel to the first direction, and both are horizontal directions.

[0064] Optionally, in some other embodiments of the present invention, the third direction may also be spaced apart from the first direction by a certain angle.

[0065] In a specific embodiment of the present invention, reference Figure 1The clamping structure 310 includes a second driver 311, a third jaw 312 and a fourth jaw 313. The third jaw 312 and the fourth jaw 313 are distributed along the third direction. The second driver 311 is connected to at least one of the third jaw 312 and the fourth jaw 313, and can drive the third jaw 312 and the fourth jaw 313 to approach each other to clamp the two sides in the width direction of the fixture.

[0066] It is understandable that by arranging the third clamping jaw 312 and the fourth clamping jaw 313 on both sides of the clamping fixture in the width direction, the size of the second clamping assembly 300 in the third direction can be reduced, thereby reducing the size of the clamping mechanism of the present application in the third direction.

[0067] In some embodiments of the present invention, a first mounting surface and a second mounting surface adjacent to each other are formed on the mounting frame 100 , and the first clamping assembly 200 and the second clamping assembly 300 are respectively disposed on the first mounting surface and the second mounting surface.

[0068] It can be understood that by respectively arranging the first clamping assembly 200 and the second clamping assembly 300 on adjacent first mounting surfaces and second mounting surfaces, compared to respectively arranging the first clamping assembly 200 and the second clamping assembly 300 at opposite ends of the mounting frame 100, the overall structure of the clamping mechanism of the present application can be made more compact.

[0069] Optionally, without considering the compactness of the overall structure of the clamping mechanism, the first clamping assembly 200 and the second clamping assembly 300 may also be disposed at opposite ends of the mounting frame 100 .

[0070] In a specific embodiment of the present invention, reference Figure 1 The mounting frame 100 includes a first mounting plate 110 and a second mounting plate 120. One end of the first mounting plate 110 is connected to one end of the second mounting plate 120 to form an angle. The plate surfaces of the first mounting plate 110 and the second mounting plate 120 that are away from the angle area 101 form a first mounting surface and a second mounting surface respectively.

[0071] The transport device provided according to the second aspect of the utility model includes the clamping mechanism provided in the first aspect of the utility model; the transport device also includes a driving component, which is connected to the mounting frame 100 and is used to drive the clamping mechanism to move.

[0072] Specifically, the driving component is a robotic arm.

[0073] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
