Description

Technical Field

[0001] This utility model relates to the field of laptop computer assembly technology, and in particular to a clamping mechanism and positioning device. Background Technology

[0002] During the manufacturing process of laptops, the keyboard module and screen module need to be pivotally connected. To improve the alignment and assembly accuracy, locking devices are usually used for automatic alignment. For example, Chinese utility model patent CN202123368123.5 discloses an automatic correction locking device for laptop assembly, including a carrier and a fine-tuning mechanism. The screen module is supported on the carrier, and the keyboard module is stacked on top of the screen module. There are two fine-tuning mechanisms, one on each side of the carrier. By pushing the keyboard module in the carrier with the fine-tuning mechanism, the keyboard module moves slightly relative to the screen module to ensure that the gap between the keyboard module and the screen module is within acceptable limits. However, with the above structure, the pushing angle of the fine-tuning mechanism is fixed. If the keyboard module is misaligned, the fine-tuning mechanism cannot reliably contact and push the keyboard module.

[0003] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a clamping mechanism and positioning device that can reliably push the product when it is tilted.

[0005] The purpose of this utility model is achieved through the following technical solution: a clamping mechanism, comprising:

[0006] The drive module has two output terminals that can move towards or away from each other along the X-axis.

[0007] There are two grippers, each connected to a different output terminal of the drive module.

[0008] The gripper includes a support, a clamping member, and an elastic member. The clamping member is disposed on the support and can rotate about a direction parallel to the Z-axis. The clamping member is located on one side in the X-axis direction. The elastic member is connected between the support and the connecting side of the clamping member away from the clamping side. There are several elastic members, which are disposed at both ends of the connecting side in the Y-axis direction.

[0009] Furthermore, the support includes:

[0010] Support body;

[0011] The connecting part extends upward from the top surface of the main body of the support;

[0012] The clamping member is located above the support body, and a rotating shaft is connected between the clamping member and the support body to allow the clamping member to rotate relative to the support body. The connecting side is arranged opposite to the connecting part, and the elastic member is connected between the connecting side and the connecting part.

[0013] Furthermore, the top surface of the support body is recessed inward to form a first connecting hole, the top surface of the clamping member is recessed inward to form a second connecting hole extending to the bottom surface, and the rotating shaft is connected between the first connecting hole and the second connecting hole.

[0014] Furthermore, the rotating shaft includes:

[0015] The rod body passes through the second connecting hole, and its lower end is threadedly connected to the first connecting hole;

[0016] A cap body is connected to the upper end of the rod body, and its outer periphery protrudes relative to the outer periphery of the rod body to limit the clamping member between the top surfaces of the cap body and the support body.

[0017] A bearing is provided between the second connecting hole and the rod body.

[0018] Furthermore, the elastic element is a spring, and its extension direction is parallel to the X-axis direction. The connecting part has a mounting hole recessed on both the side facing the connecting side and the connecting side. The end of the elastic element is embedded in the mounting hole.

[0019] Furthermore, the support includes a limiting portion extending from the top of the connecting portion along the X-axis direction toward the clamping member, a slot being formed between the limiting portion and the top surface of the support body, and the clamping member being adapted to be inserted into the slot along the X-axis direction so as to be limited in the Z-axis direction.

[0020] Furthermore, there are two limiting parts, which are respectively located on both sides of the connecting part in the Y-axis direction, and the first connecting hole is located in the middle position between the two limiting parts;

[0021] The connecting side is recessed inward to form a recessed portion. There are two recessed portions, which are respectively located on both sides of the clamping member in the Y-axis direction, so as to correspond one-to-one with the limiting portion. The recessed portion and the limiting portion are embedded and cooperate.

[0022] Furthermore, the recessed portion extends upward through to the top surface of the clamping member and extends along the Y-axis direction through to the side surface of the clamping member. The two limiting portions have a first side arranged opposite to each other and a second side located at the extension end. The first side is arranged opposite to the inner wall of the recessed portion in the Y-axis direction and has a gap. The second side is arranged opposite to the inner wall of the recessed portion in the X-axis direction and has a gap.

[0023] Furthermore, the clamping member has flexible blocks on both sides in the Y-axis direction, and the flexible blocks protrude relative to the clamping side.

[0024] In addition, this utility model also provides a positioning device, including the aforementioned clamping mechanism.

[0025] Compared with the prior art, the present invention has the following beneficial effects: By adopting the above structure, the two clamping members are suitable for moving towards each other under the drive of the drive module to clamp and center the product. When the clamping members approach and contact the product, they can adaptively rotate according to the actual side of the product to adjust to the angle that is most closely attached to the side of the product, making the pushing and clamping of the clamping members more reliable. After adjustment, the elastic member at one end is compressed and the elastic member at the other end is stretched. When the clamping members move away from the product, the clamping members can quickly and reliably return to the preset position under the action of the elastic members at both ends.

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0032] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] Please see Figures 1 to 3 As shown, the clamping mechanism corresponding to a preferred embodiment of the present invention includes: a drive module 100 having two output ends that can move towards or away from each other along the X-axis; and two grippers 200, which are respectively connected to different output ends of the drive module 100. Each gripper 200 includes a support 210, a clamping member 220, and an elastic member 230. The clamping member 220 is disposed on the support 210 and can rotate about a direction parallel to the Z-axis. One side of the clamping member 220 in the X-axis direction is the clamping side 221. The elastic member 230 is connected between the support 210 and the connecting side 222 of the clamping member 220 away from the clamping side 221. Several elastic members 230 are distributed at both ends of the connecting side 222 in the Y-axis direction.

[0035] By adopting the above structure, the two clamping members 220 are adapted to move towards each other under the drive of the drive module 100 to clamp and center the product. When the clamping member 220 approaches and contacts the product, it can adaptively rotate according to the actual side of the product to adjust to the angle that is most closely attached to the side of the product, making the pushing and clamping of the clamping member 220 more reliable. After adjustment, the elastic member 230 at one end is compressed and the elastic member 230 at the other end is stretched. When the clamping member 220 moves away from the product, it can quickly and reliably return to the preset position under the action of the elastic members 230 at both ends.

[0036] Furthermore, the drive module 100 can employ a lead screw with a double helix structure in conjunction with a motor, or a linear motor with two movers, giving the drive module 100 two output ends. The clamping mechanism includes a base 300 for mounting the drive module 100, and a slide rail assembly 400 is provided between the base 300 and the gripper 200 to improve the stability of the gripper 200 during movement.

[0037] Further, the support 210 includes a support body 211 and a connecting portion 212. The support body 211 is connected to the output end of the drive module 100, and the connecting portion 212 extends upward from the top surface of the support body 211. A clamping member 220 is located above the support body 211, and a rotating shaft 240 is connected between the clamping member 220 and the support body 211 to allow the clamping member 220 to rotate relative to the support body 211. A connecting side 222 is arranged opposite to the connecting portion 212, and an elastic member 230 is connected between the connecting side 222 and the connecting portion 212. Specifically, a first connecting hole 2111 is recessed inward on the top surface of the support body 211, and a second connecting hole 223 extending to the bottom surface is recessed inward on the top surface of the clamping member 220. The rotating shaft 240 is connected between the first connecting hole 2111 and the second connecting hole 223.

[0038] The pivot member 240 includes a rod 241 and a cap 242. The rod 241 passes through the second connecting hole 223 and its lower end is threadedly connected to the first connecting hole 2111. The cap 242 is located at the upper end of the rod 241, and its outer periphery protrudes relative to the outer periphery of the rod 241 to limit the clamping member 220 between the top surface of the cap 242 and the support body 211. A bearing member 250 is provided between the second connecting hole 223 and the rod 241 to improve the smoothness of rotation of the clamping member 220.

[0039] Furthermore, the elastic element 230 is a spring, and its extension and contraction direction is parallel to the X-axis direction. The connecting part 212 has a mounting hole 2121 recessed on the side facing the connecting side 222 and the connecting side 222. The two ends of the elastic element 230 are respectively embedded in different mounting holes 2121, which improves the reliability of the elastic element 230 after installation.

[0040] Furthermore, the support 210 includes a limiting portion 213 extending from the top of the connecting portion 212 along the X-axis direction to the clamping member 220. A slot 214 is formed between the limiting portion 213 and the top surface of the support body 211. The clamping member 220 is adapted to be inserted into the slot 214 along the X-axis direction to achieve its limiting in the Z-axis direction and improve installation reliability.

[0041] There are two limiting portions 213, located on both sides of the connecting portion 212 in the Y-axis direction. The first connecting hole 2111 is located in the middle between the two limiting portions 213. Two recessed portions 224 are formed inwardly on the connecting side 222, located on both sides of the clamping member 220 in the Y-axis direction. The second connecting hole 223 is located in the middle between the two recessed portions 224. The limiting portions 213 and the recessed portions 224 correspond one-to-one, and the recessed portions 224 are fitted into the limiting portions 213.

[0042] The recess 224 extends upward through the top surface of the clamping member 220 and extends along the Y-axis to one side of the clamping member 220, which is the side adjacent to the recess 224. That is, two sides of the recess 224 are open sides, facilitating engagement between the recess 224 and the limiting portion 213. The inner wall of the recess 224 in the Z-axis direction is in contact with the bottom surface of the limiting portion 213. The two limiting portions 213 have a first side 2131 and a second side 2132 located at their extended ends. The first side 2131 is arranged opposite to the inner wall of the recess 224 in the Y-axis direction with a gap between them. The second side 2132 is arranged opposite to the inner wall of the recess 224 in the X-axis direction with a gap between them, thus limiting the maximum rotation angle of the clamping member 220.

[0043] By adopting the above structure, it is easy to quickly align the clamping member 220 and the support 210. The connection between the clamping member 220 and the support 210 is very stable. Furthermore, the recessed portion 224 and the limiting portion 213 of the above structure make it less likely to be damaged when the clamping member 220 is rotated to the limit position.

[0044] Furthermore, the clamping member 220 is provided with flexible blocks 260 on both sides in the Y-axis direction. The flexible blocks 260 can be made of materials such as rubber and silicone. The flexible blocks 260 are used to contact the product to prevent damage to the product during the clamping process.

[0045] In addition, this utility model also provides a positioning device, including the aforementioned clamping mechanism and carrier (not shown in the figure). The carrier carries the product with positioning, and the clamping mechanism can position the product on the carrier to facilitate subsequent locking.

[0046] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
