[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

The directional terms used are for the purpose of explaining and understanding this utility model, and are not intended to limit this utility model.

[0030] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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 utility model according to the specific circumstances.

[0032] There are multiple injection molding modules. Due to frequent injection molding and the need for cleaning, the position of the injection molding modules may deviate when they are reinstalled after cleaning. After the relative positions of multiple injection molding modules change, the clamping mechanism cannot align with each injection molding module, thus failing to clamp the material accurately.

[0033] The following is a preferred embodiment of a modular gripper structure provided by this utility model that can solve the above-mentioned technical problems.

[0034] A preferred embodiment of this utility model provides a modular gripper structure. Please refer to... Figure 1 , Figure 2 and Figure 3 The modular gripper structure is used to precisely grip materials on multiple injection molding modules. The modular gripper structure includes a support frame 11 and multiple clamping modules 12. The support frame 11 has multiple vertically penetrating mounting slots 111. The multiple clamping modules 12 are used to precisely grip materials on the injection molding modules. Each clamping module 12 is detachably installed in its respective mounting slot 111, and the clamping modules 12 have clearance fits with the transverse and longitudinal sidewalls of the mounting slots 111. Each clamping module 12 has a first positioning structure 123 for positioning with the injection molding modules. The modular gripper structure illustrated in this embodiment has four mounting slots 111 and four clamping modules 12.

[0035] The modular gripper structure of this utility model allows each gripper module 12 to be detachably installed in its respective mounting slot 111. When one gripper module 12 malfunctions, it can be removed and replaced as a whole, facilitating maintenance, reducing maintenance time, and minimizing impact on equipment operation. The gripper modules 12 are clearance-fitted with both the transverse and longitudinal sidewalls of the mounting slot 111. When the modular gripper structure uses the first positioning structure 123 to position and connect the gripper modules 12 and the injection molding module, the position of the gripper modules 12 can be automatically adjusted transversely and longitudinally, ensuring that the position of each gripper module 12 is aligned with the corresponding injection molding module for accurate material clamping.

[0036] Please refer to Figure 2The first positioning structure 123 is configured as a positioning post, which is located at the bottom of the fixture module 12 and is used for positioning with the guide structure of the injection molding module. The guide structure can be a positioning hole. The position of the fixture module 12 can be easily adjusted by the cooperation of the positioning post and the guide structure.

[0037] Please refer to Figure 2 The end of the first positioning structure 123 is tapered, which is used to guide it into the guiding structure of the injection molding module. This structure facilitates the alignment of the relative positions of each fixture module 12 and the injection molding module.

[0038] The injection molding module has multiple guiding structures, and the number of first positioning structures 123 matches the number of guiding structures in the injection molding module, which makes the position of the fixture module 12 more accurate. Each fixture module 12 illustrated in this embodiment has eight first positioning structures 123.

[0039] Please refer to Figure 3 The bottom of the mounting groove 111 is provided with a first limiting piece 1111. The edge of the clamp module 12 is supported on the first limiting piece 1111. The first limiting piece 1111 is a long strip that is horizontally arranged along the groove wall of the mounting groove 111. It can prevent the clamp module 12 from detaching from the mounting groove 111 from below and vertically limit the clamp module 12.

[0040] Please refer to Figure 3 Each mounting slot 111 is provided with two first limiting pieces 1111, which are located on two opposite side walls of the mounting slot 111. The two first limiting pieces 1111 can stably support the clamp module 12. The relatively small number of them can reduce friction and facilitate the automatic adjustment of the position of the clamp module 12.

[0041] Please refer to Figure 4 The clamp module 12 has two protruding second limiting pieces 121 on its two opposite edges. The second limiting pieces 121 abut against the first limiting piece 1111 in the vertical direction, and the second limiting pieces 121 are located above the first limiting piece 1111. When the mounting groove 111 is shallow, the top of the clamp module 12 does not need to protrude from the mounting groove 111, resulting in a compact structure.

[0042] Please refer to Figure 2 and Figure 4 The second limiting piece 121 is located at the top edge of the clamping module 12, and multiple grippers 122 are provided below the clamping module 12. With the above structure, the grippers 122 protrude downwards from the bottom of the support frame 11, making it convenient to grip materials.

[0043] Please refer to Figure 3The support frame 11 is provided with threaded holes 112, which are located on one side of the mounting groove 111 in the horizontal direction. The clamping modular structure also includes bolts (not shown in the figure). The bolt shank is threaded vertically in the threaded hole 112, and the bolt nut protrudes horizontally from the groove wall of the mounting groove 111 and is located above the clamping module 12. Vertically, the bolt nut and the clamping module 12 are clearance-fitted. By limiting the clamping module 12 with the bolt nut, the clamping module 12 can be prevented from detaching from the mounting groove 111 from above. At the same time, the clearance between the nut and the clamping module 12 avoids affecting the movement of the clamping module 12. In this embodiment, each clamping module 12 has four threaded holes 112 around it.

[0044] Please refer to Figure 3 and Figure 4 The clamp module 12 is square with its four corners set at bevels, and the shape of the mounting slot 111 matches that of the clamp module 12. This facilitates the correct placement of the clamp module 12 into the mounting slot 111.

[0045] Please refer to Figure 2 The support frame 11 is provided with a second positioning structure 113, which can be positioned with the support frame that carries the injection molding module, so that the support frame 11 and the support frame that carries the injection molding module are aligned and guided, thereby facilitating the alignment of the fixture module 12.

[0046] Method of using the modular gripper structure of the preferred embodiment of this utility model:

[0047] When installing the clamp module 12, place the clamp module 12 in the mounting slot 111, ensuring that the first limiting piece 1111 abuts against the second limiting piece 121. Screw the bolt into the threaded hole 112, maintaining a clearance fit between the bolt nut and the clamp module 12 in the vertical direction. When installing the clamp module 12 to grip materials, firstly, the second positioning structure 113 guides the support frame 11 and the support frame carrying the injection molding module. Simultaneously, the positioning pin is inserted into the guiding structure of the injection molding module. If the clamp module 12 and the injection molding module cannot be accurately aligned, as the positioning pin penetrates deeper into the guiding structure, the guiding structure will force the positioning pin to move, thereby causing the clamp module 12 to move horizontally, thus aligning the clamp module 12 with the injection molding module for accurate material gripping.

[0048] This is the method of using the modular gripper structure of this preferred embodiment.

[0049] This utility model features a modular gripper structure, where each gripper module can be detachably installed in its respective mounting slot for easy maintenance. The gripper modules are clearance-fitted to both the transverse and longitudinal sidewalls of the mounting slot. When the modular gripper structure uses the first positioning structure to position and connect the gripper modules and the injection molding module, the positions of the gripper modules can be adjusted transversely and longitudinally, ensuring that each gripper module is aligned with its corresponding injection molding module for accurate material clamping.

[0050] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be included within the scope of protection of the present invention.
