AI Technical Summary
In the current laser head lens processing, the part picking structure is complex and the airtightness requirement is high, resulting in a high failure rate and easy interference with the air pipe. In addition, the existing part picking and placing robot has high energy consumption and is not clean enough.
The device employs a structure comprising a mounting rod, an outer protective plate, and a suction cup. The suction cup consists of a shaping sleeve and a spring piece. The spring piece has an adsorption block and an electromagnet in the middle. The negative pressure is controlled by energizing and de-energizing the electromagnet to adsorb and release the lens. The air pressure is regulated by an overflow hole, enabling the picking and placing of parts without the need for an external air circuit.
It enables simple lens gripping and release, reduces energy consumption, simplifies the operation process, avoids air path interference, and improves the reliability of the equipment and the cleanliness of operation.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laser head processing technology and relates to a laser head lens pressing and taking structure. Background Technology
[0002] During the processing of laser head lenses, they are generally picked up by a suction cup. Controlling air pressure is a conventional structural principle. This requires high sealing of each airtight component in the airflow path, resulting in a high failure rate. In addition, since laser head lenses are small-sized workpieces, they are usually picked up in groups of several, which makes the pipeline complex and prone to interference with the air pipes during the operation of picking up and placing parts. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a laser head lens pressing and releasing structure. The technical problem this invention aims to solve is how to achieve simple lens gripping and release.
[0004] The purpose of this utility model can be achieved through the following technical solution: A laser head lens pressing and removing structure, characterized in that it includes a mounting rod, an outer protective plate and a suction cup, the suction cup includes a shaping sleeve fixedly connected to the inner wall of the outer protective plate and a spring piece located at the opening of the shaping sleeve, the spring piece closes the opening of the shaping sleeve to form a sealed air cavity, the spring piece has an iron adsorption block in the middle, the shaping sleeve in the sealed air cavity has an electromagnet in the middle, and the shaping sleeve has an overflow hole communicating with the outside.
[0005] Furthermore, the outer sleeve has a locking head, and the inner wall of the outer protective disc has a locking slot that matches the locking head.
[0006] Furthermore, a reset spring is provided between the electromagnet and the adsorption block.
[0007] When the electromagnet is energized, it generates a magnetic force that attracts the adsorption block. This attraction causes the adsorption block and electromagnet to interact when the spring plate is concave. Before concave movement, the spring plate presses against the lens surface. Since the lens is a convex lens, the pressure causes the spring plate to concave. When the lens is pressed vertically, the magnetic force further inclines the spring plate inward, creating a negative pressure between the spring plate and the lens surface, thus adsorbing the lens. An overflow hole is used to vent air, maintaining a normal or slightly higher pressure within the sealed air chamber. When the lens needs to be released, the electromagnet is de-energized, and the restoring force of the spring plate and the return spring weakens the negative pressure between the lens and the spring plate, allowing the lens to detach. Compared to existing methods, this method eliminates the need for an external air circuit, consumes less energy, and produces a cleaner, more efficient robotic arm for picking up and placing parts.

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0012] like Figure 1 and Figure 2 The laser head lens pressing and removing structure shown includes a mounting rod 1, an outer protective plate 2, and a suction cup. The suction cup includes a shaping sleeve 3 fixedly connected to the inner wall of the outer protective plate 2 and a spring piece 4 located at the opening of the shaping sleeve 3. The spring piece 4 closes the opening of the shaping sleeve 3 to form a sealed air chamber 5. An iron adsorption block 6 is located in the middle of the spring piece 4. An electromagnet 7 is located in the middle of the shaping sleeve 3 within the sealed air chamber 5. The shaping sleeve 3 has an overflow hole 8 communicating with the outside. The outer protective plate 2 also has a pressure relief channel corresponding to the overflow hole 8. A battery powered by a rechargeable battery can be installed inside the mounting rod 1, and the electromagnet 7 can be remotely controlled by switching it on and off. A locking head 9 is located outside the shaping sleeve 3, and a locking slot adapted to the locking head 9 is located on the inner wall of the outer protective plate 2. A return spring 10 is provided between the electromagnet 7 and the adsorption block 6.
[0013] When the electromagnet 7 is energized, it generates a magnetic force that attracts the adsorption block 6. This magnetic force then attracts the adsorption block 6 and the electromagnet 7 when the spring 4 is concave. Before concavity, the spring 4 is pressed against the lens surface. Since the lens is a convex lens, the pressure causes the spring 4 to concave. When the lens is pressed vertically, the magnetic force further inclines the spring 4 inward, creating a negative pressure between the spring 4 and the lens surface, thus adsorbing the lens. The overflow hole 8 is used to exhaust air, maintaining a normal or slightly higher pressure within the sealed air chamber 5. When the lens needs to be released, the electromagnet 7 is de-energized. The restoring force of the spring 4 and the restoring force of the return spring 10 weaken the negative pressure between the lens and the spring 4, allowing the lens to detach. Compared to existing methods, this method eliminates the need for an external air path, consumes less energy, and produces a cleaner robotic arm for picking up and placing parts.
[0014] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
