Description

Technical Field

[0001] The present invention relates to the technical field of product clamping, and in particular to a constant-force spring telescopic feeding and taking mechanism. Background Art

[0002] In modern industrial production, automated feeding and retrieving mechanisms are widely used in various production lines to improve production efficiency, reduce manual labor, and ensure product quality. Demand for automated feeding and retrieving systems is particularly increasing in industries such as electronics, automotive, and food packaging. However, existing feeding and retrieving mechanisms still face some practical challenges, particularly when handling multi-layer stacked circular ring-shaped products. Ensuring smooth and stable material retrieval poses a technical challenge. Traditional feeding and retrieving mechanisms typically utilize fixed guard bars or rigid structures inserted into the center of the circular ring to prevent it from falling out. However, this design can easily obstruct the product during retrieval. Especially in multi-layer stacking, the fixed guard bar can hinder lateral movement of the product, resulting in unsmooth retrieval and even damage. Using an upward retrieval method, the suction between the circular rings can lift up a second circular ring, necessitating height adjustment of the guard bar during retrieval. Currently, the predominantly servo-driven approach in the market is costly and inconvenient to maintain. Summary of the Invention

[0003] The purpose of the present invention is to provide a constant force spring telescopic feeding and taking mechanism to solve the technical problems raised in the background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A constant-force spring telescopic feeding and picking mechanism comprises a manipulator and a supporting material rack, the manipulator being provided with a clamping claw for clamping annular products, the supporting material rack being used to carry the annular products and being provided with a telescopic guard rod and a constant-force spring portion, the telescopic guard rod being located on the side of the supporting material rack and vertically slidingly engaged with the supporting material rack, the top of the telescopic guard rod extending to the center of the supporting material rack to prevent the annular products from falling off the supporting material rack; the constant-force spring portion being provided on the supporting material rack and one end of the constant-force spring portion being connected to the bottom of the telescopic guard rod, the constant-force spring portion supporting the telescopic guard rod in an elastically pushing manner; the manipulator being further provided with a pressing piece and the pressing piece being used to press the telescopic guard rod downward.

[0006] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:

[0007] In an optional solution: the pressing member includes a pressing cylinder and a pressing wheel, the pressing cylinder is fixed on the manipulator and the telescopic end of the pressing cylinder faces downward, and the pressing wheel is arranged at the telescopic end of the pressing cylinder and rotates with it.

[0008] In an optional solution, the constant force spring portion is made of high-elasticity alloy steel material.

[0009] By adopting the above technical solution, the present invention has the following beneficial effects:

[0010] The present invention uses a telescopic mechanism without an additional electric drive, resulting in low cost, simple structure, and easy maintenance. The constant-force spring allows for controllable manipulator load, making the function more reliable and stable. The manipulator does not require additional movement each time it takes a product, allowing it to stably remove all products while maintaining a substantially constant load. The present invention employs a purely mechanical, constant-force spring telescopic feeding and retrieving mechanism. The manipulator can directly utilize the telescopic rod to retrieve a single product, eliminating the need for a conventional servo lift mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0013] Notes on the accompanying drawings: robot 100, clamping claw 200, material supporting rack 300, telescopic guard rod 400, constant force spring part 500, annular product 600, pressing cylinder 700, pressing wheel 800. DETAILED DESCRIPTION

[0014] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0015] The left, right, up, and down positions of the components shown in the accompanying drawings are merely one arrangement, and the specific positions are set according to specific needs.

[0016] In one embodiment, Figure 1As shown, a constant force spring telescopic feeding and picking mechanism includes a manipulator 100 and a supporting material rack 300, wherein the manipulator 100 is provided with a clamping claw 200 for clamping an annular product 600, and the supporting material rack 300 is used to carry the annular product 600 and is provided with a telescopic guard rod 400 and a constant force spring part 500 on the supporting material rack 300, and the telescopic guard rod 400 is located on the side of the supporting material rack 300 and vertically slides with it, and the telescopic guard rod 400 is provided with a constant force spring part 500. The top of the telescopic guard rod 400 extends to the center of the supporting material rack 300 to prevent the annular product 600 from falling off the supporting material rack 300; the constant force spring part 500 is provided on the supporting material rack 300 and one end of the constant force spring part 500 is connected to the bottom of the telescopic guard rod 400, and the constant force spring part 500 supports the telescopic guard rod 400 in an elastic pushing manner; the manipulator 100 is also provided with a downward pressing piece and the downward pressing piece is used to press the telescopic guard rod 400 downward.

[0017] In the embodiment of the present invention, when taking materials, the manipulator 100 moves to the top of the supporting rack 300, and the two clamping parts of the clamping jaw 200 are respectively located on both sides of the topmost circular product 600, and the downward pressing cylinder 700 corresponds to the telescopic guard bar 400; the downward pressing part presses down the telescopic guard bar 400 and contracts it, and the top of the telescopic guard bar 400 is flush with the upper surface of the circular product 600 of the next layer; the clamping jaw 200 clamps the circular product 600 of the top layer and the manipulator moves laterally. Since the top of the telescopic guard bar 400 is flush with the upper surface of the circular product 600 of the next layer, the top of the telescopic guard bar 400 will not block the lateral movement of the circular product 600 of the top layer, and the telescopic resistance of the telescopic guard bar 400 mainly comes from the constant force spring part 500, the elastic force is not large and is basically constant, so the manipulator can take out the products with little resistance, and can take out all the products.

[0018] In one embodiment, Figure 1 As shown, the pressing member includes a pressing cylinder member 700 and a pressing wheel 800. The pressing cylinder member 700 is fixed on the manipulator 100 and the telescopic end of the pressing cylinder member 700 faces downward. The pressing wheel 800 is arranged at the telescopic end of the pressing cylinder member 700 and rotates with it. In the embodiment of the present invention, the pressing cylinder member 700 drives the pressing wheel 800 to rise and fall through its own telescopic movement. The pressing wheel 800 moves downward and pushes the telescopic guard bar 400 downward so that its top is flush with the upper surface of the second-layer annular product 600. When the manipulator clamps the product horizontally and moves it away, the friction between the pressing wheel 800 and the top of the telescopic guard bar 400 effectively reduces the damping effect of the pressing wheel 800.

[0019] In one embodiment, Figure 1 As shown, the constant force spring portion 500 is made of high elastic alloy steel material to ensure good elasticity and durability.
