Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to an elastic clamping mechanism. Background Technology

[0002] When electronic products are processed or inspected, they need to be positioned. However, if the product is transported to the positioning fixture by a robot arm and the descent distance is slightly too far, it may cause the bottom of the product to be bumped and damaged, which may also lead to damage to the internal components.

[0003] Existing technologies also disclose some clamping fixtures for products, such as the one with authorization announcement number CN203843716U, entitled "An Automatically Centering Workpiece Fixture," which includes a pair of clamping arms that can be clamped and released relative to each other under the action of a power device. The opposing surfaces of the two clamping arms respectively form V-shaped clamping surfaces, and at least one V-shaped clamping surface is provided with an elastic clamping pad; a rack is fixed to the rear end of each of the two clamping arms, the two racks are parallel and a gear meshes between them; at least one clamping arm is provided with a power device that enables the two clamping arms to clamp and release relative to each other. Obviously, this fixture cannot protect the bottom of the product, so the bottom of the product is still easily damaged, and this solution is not suitable for clamping products with a slightly larger volume.

[0004] Therefore, the technical problem to be solved by this application is: how to prevent the bottom of the product from deforming when the product is fed into the fixture. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an elastic clamping mechanism. The mounting plate is elastically installed through an elastic support member, so that the clamping component can move elastically. When the product is placed downward onto the clamping component, if the downward distance of the product is slightly large, the deformation of the elastic support member can provide space for the product to move downward, thereby avoiding deformation caused by bumps or squeezing of the bottom of the product.

Detailed Implementation

[0030] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0031] like Figures 1 to 6 As shown, this embodiment proposes an elastic clamping mechanism, including:

[0032] An elastic support assembly includes a fixed plate 11, a lifting plate 12, an elastic support member 13, a mounting plate 14, and a pusher member 15. The lifting plate 12 is slidably mounted in the guide hole of the fixed plate 11 in the vertical direction via a guide rod 16. The pusher member 15 is fixed on the fixed plate 11 and has an output end that moves in the vertical direction. The output end of the pusher member 15 is used to drive the lifting plate 12 to move in the vertical direction. The mounting plate 14 is mounted on the lifting plate 12 via the elastic support member 13.

[0033] A clamping assembly 17 is mounted on the mounting plate 14 and is used to clamp the product 18.

[0034] In this design, the clamping component 17 is mounted on the mounting plate 14, and the mounting plate 14 is elastically mounted by the elastic support 13, so that the clamping component 17 can move elastically. When the product 18 is dropped onto the clamping component 17, if the product 18 is dropped a little further, the elastic support 13 will deform, providing space for the product 18 to move downward, thereby avoiding deformation caused by bumps or squeezing at the bottom of the product 18.

[0035] As one embodiment of this example, the upper surface of the mounting plate 14 is used to mount the product 18, and the two ends of the mounting plate 14 are provided with clearance channels 20.

[0036] The clamping assembly 17 has two clamping plates 19, which are respectively disposed in the clearance channels 20 at both ends of the mounting plate 14, and the clamping plates 19 are used to clamp the product 18.

[0037] In this solution, the product 18 is clamped by two clamping plates 19 moving close to each other, and the product 18 can be released when the two clamping plates 19 move away from each other.

[0038] As one embodiment of this invention, the clamping assembly 17 includes:

[0039] A clamping member 21 is mounted on the lower surface of the mounting plate 14, and the clamping member 21 has two clamping fingers 22;

[0040] A slide rail assembly, the slide rail assembly including a guide rail 23 and a slider 24, the guide rail 23 being fixed to the lower surface of the mounting plate 14, and two sliders 24 being mounted on the guide rail 23;

[0041] Each slider 24 has a movable plate 25, and each movable plate 25 has a clamping plate 19 fixed on it. Each movable plate 25 is also connected to a clamping finger 22.

[0042] The clip 22 is inserted into a slot or mounting groove on the movable plate 25. Alternatively, the clip 22 can be fixedly connected to the movable plate 25.

[0043] The clamping component 21 in this solution uses a clamping cylinder, which is existing technology, and has two clamping fingers 22 that can move closer to or further apart from each other. Alternatively, the clamping component 21 can also use other clamping solutions in the prior art, or it can be a robotic arm.

[0044] In this solution, a slide rail assembly is used to install the moving plate 25, which enables the moving plate 25 to move more smoothly. The clamping fingers 22 control the two moving plates 25 to move closer or further apart, so that the clamping plates 19 on the two moving plates 25 can clamp or release the product 18.

[0045] As one embodiment of this example, each of the clamping plates 19 is provided with a clamping block 26 at its top end, and the clamping block 26 is used to clamp the top end of the product 18.

[0046] Furthermore, the top of the clamping block 26 is provided with a limiting protrusion 27, which is used to clamp onto the top of the product 18.

[0047] The technical advantage of this solution is that it can be used to clamp the top of product 18, thereby improving the stability of clamping product 18.

[0048] In one embodiment of this invention, the number of clamping components 17 is multiple, and the number of mounting plates 14 is the same as the number of clamping components 17. This is used to simultaneously clamp multiple products 18. Alternatively, the number of clamping components 17 may be two.

[0049] In one embodiment of this invention, the elastic support 13 includes a sliding rod 28 and a spring 29. The sliding rod 28 is slidably mounted on the lifting plate 12 in a vertical direction. The top of the sliding rod 28 is fixed with the mounting plate 14. The spring 29 is sleeved on the sliding rod 28 and is located between the mounting plate 14 and the lifting plate 12.

[0050] In one embodiment of this invention, the pushing member 15 is a telescopic member. Further, the pushing member 15 is a cylinder or a hydraulic cylinder.

[0051] In addition, the fixing plate 11 in this solution can be installed on a mobile platform, on the upper surface of the cabinet, or on a processing platform. The applicable scenarios for the fixing plate 11 in this solution can be selected according to the specific application scenario.

[0052] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
