Description

Technical Field

[0001] This utility model relates to the field of column cap production technology, specifically to an automatic column cap welding device. Background Technology

[0002] The corrugated guardrail post cap is an important component installed on the top of the corrugated guardrail post, playing a crucial role in traffic safety facilities. Firstly, the post cap strengthens the overall strength of the post by increasing its weight and surface area through proper design, dispersing wind pressure and lateral forces, and improving the impact resistance of the guardrail system, making the post less prone to tilting or collapsing under strong winds and other external forces. Secondly, it provides rust and corrosion protection, preventing rain, snow, and dust from entering the post and extending its service life.

[0003] Currently, column cap products on the market are mainly welded manually or robotically. Manual welding requires highly skilled workers, poses significant health risks, and is inefficient and difficult to guarantee in terms of quality. While robotic welding avoids the risks to workers, it is less efficient and requires frequent material handling, resulting in a cluttered work environment. Utility Model Content

Detailed Implementation

[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. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] In existing technologies, manual welding of column caps requires high skill levels from employees, poses significant health risks, and is inefficient with poor quality control. While robotic welding avoids these risks, it is less efficient, requires frequent material handling, and creates a cluttered work environment.

[0030] To address the aforementioned issues, this invention employs a one-to-two conveyor, dividing the cap cups on the conveyor belt into two rows, allowing the feeding mechanism to grasp two cap cups at a time. The rotary mechanism adjusts the work position by rotation, enabling simultaneous feeding, welding, and unloading, significantly improving welding efficiency.

[0031] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] Example 1 of the automatic column cap welding equipment provided by this utility model:

[0034] like Figures 1-5 As shown, the automatic column cap welding equipment includes a conveying mechanism 1, a feeding mechanism 2, a rotating mechanism 3, a welding mechanism 4, and a discharging mechanism 6.

[0035] The conveying mechanism 1 is used to convey cap bowls; in this embodiment, the conveying mechanism 1 is a one-to-two conveyor, which has two material positions to facilitate grabbing two cap bowls at a time. The one-to-two conveyor includes two lifting cylinders, and a material platform is set on the top of the lifting cylinders. Several cap bowls are stacked on the material platform. Each time the feeding mechanism 2 grabs a cap bowl, the lifting cylinder rises one working position.

[0036] The feeding mechanism 2 is used to grab the cap cup from the conveying mechanism 1 and place it on the welding station 320 of the rotary mechanism 3. The feeding mechanism 2 includes a horizontal feeding cylinder, which is connected to a vertical feeding cylinder. Two sets of pneumatic grippers are connected to the bottom of the vertical feeding cylinder. The horizontal feeding cylinder is fixedly mounted on an external mounting frame. Both the horizontal and vertical feeding cylinders are three-axis cylinders. In other embodiments, the pneumatic grippers can also be replaced by an electromagnet adsorption structure or a negative pressure adsorption structure.

[0037] In this embodiment, the rotary mechanism 3 includes a frame 5 and a turntable 310 rotatably mounted on the frame 5. The turntable 310 is driven by a cam divider. Several welding stations 320 are evenly distributed on the turntable 310 in a ring. The welding stations 320 are used to place the cap cup and cap handle to be welded. In this embodiment, there are 12 sets of welding stations 320. The welding station 320 includes a positioning baffle 322 and a support frame 321 set above the positioning baffle 322 to keep the cap handle vertical. The positioning baffle 322 can be arranged in a U-shape, arc shape, or V-shape. Its arrangement or setting can be matched with the cap cup. The support frame 321 has an L-shaped or U-shaped magnet groove. The cap handle is fixed on the support frame 321 by magnetic attraction. The openings of the positioning baffle 322 and the support frame 321 face outwards, which makes it convenient to directly remove the welded cap.

[0038] In this embodiment, the cap handle is manually inserted into the welding station 320. In other embodiments, a cap handle insertion structure can also be designed to achieve fully automatic welding.

[0039] The welding mechanism 4 is set around the turntable 310 and corresponds to the welding station 320. The welding mechanism 4 has at least four sets. The welding mechanism 4 includes a horizontal welding cylinder 410 and a vertical welding cylinder 420 connected to the horizontal welding cylinder 410. The bottom of the vertical welding cylinder 420 is connected to a welding torch 430.

[0040] The unloading mechanism 6 is fixedly mounted on the frame 5 and is used to remove the welded column caps. The unloading mechanism 6 includes a horizontal unloading cylinder 610 and a gripping mechanism 620 connected to the horizontal unloading cylinder 610. In this embodiment, the gripping mechanism 620 includes a bidirectional cylinder and a gripper connected to the bidirectional cylinder. During unloading, the bidirectional cylinder retracts, and the horizontal unloading cylinder 610 drives the bidirectional cylinder to pass between the two column caps. The retraction of the bidirectional cylinder is to provide clearance. When the bidirectional cylinder passes through the column cap, the bidirectional cylinder extends and opens, and then the horizontal unloading cylinder 610 retracts, the gripper clamps the column cap, causing the column cap to separate from the support frame 321 and fall into the finished product frame.

[0041] In other embodiments, the gripping mechanism 620 may also employ a claw structure, an electromagnetic or negative pressure adsorption structure, etc.

[0042] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
