Description

Technical Field

[0001] This utility model relates to the field of photoelectric sensor accessories technology, specifically a metal sheet metal groove-type photoelectric baffle. Background Technology

[0002] In industrial automation, slotted photoelectric sensors are widely used for object presence detection, position positioning, and product counting. Their working principle involves placing an infrared emitter and receiver on either side of a U-shaped structure. When an object passes through the U-shaped slot, blocking the light path, the sensor outputs a signal. To accommodate objects of different sizes or for precise positioning, a "photoelectric baffle" is typically installed on the moving workpiece or robotic arm. This baffle extends into the U-shaped slot of the photoelectric sensor, triggering the signal by blocking the light path.

[0003] Existing technology analysis (combined with real-world examples): Currently, most of the metal sheet metal slotted photoelectric baffles commonly found on the market have simple structures and are usually integrally formed sheet metal parts.

[0004] In practical applications, this existing technology has the following significant drawbacks: Low adjustment accuracy and difficult installation and debugging: On high-speed, high-precision automated production lines, the relative position of the photoelectric sensor and the baffle is extremely critical. Existing integrated baffles can only be coarsely adjusted during installation by loosening screws and manually tapping or moving the baffle, making it difficult to achieve micron-level precise alignment. The debugging process is time-consuming and labor-intensive, and requires a high level of operator experience. For example, on electronic component pick-and-place machines, a deviation of even a fraction of a millimeter in baffle position can lead to nozzle failure to pick up components or positioning errors.

[0005] Poor vibration resistance and insufficient stability: Many devices (such as stamping presses and CNC machine tools) generate significant vibrations during operation. The rigidity of the integrated, cantilevered baffle structure is relatively weak, making it prone to resonance or slight displacement under vibration. This can lead to false or missed triggering of photoelectric sensor signals, affecting the stability and reliability of the entire system.

[0006] Therefore, we have made improvements to the aforementioned existing technologies based on actual usage. Utility Model Content

Example 1:

[0026] Please see Figure 1-3 This utility model provides a technical solution: a metal sheet metal groove-type photoelectric baffle, including a mounting base 1 and a baffle body 6; A guide groove 3 is horizontally provided at the top center of the mounting base 1. The guide groove 3 is used to guide and restrict the movement trajectory of the sliding component. A sliding baffle seat 4 is movably connected to the top of the guide groove 3, and a slider 5 matching the guide groove 3 is provided at the bottom of the sliding baffle seat 4. The slider 5 can ensure that the sliding baffle seat 4 is smooth and accurate during the sliding process. A baffle body 6 is provided on the top of the sliding baffle seat 4. The baffle body 6 is used to realize the function of blocking photoelectric signals. A locking bolt 7 is vertically provided through the front and rear ends of the top right side of the sliding baffle seat 4, and the bottom of the locking bolt 7 is fitted and connected to the front and rear ends of the top of the guide groove 3. The sliding baffle seat 4 can be quickly fixed and released by tightening the locking bolt 7. A connecting groove 8 is horizontally arranged at the bottom of the inner cavity of the guide groove 3, and a slot 9 matching the connecting groove 8 is horizontally arranged at the top center of the mounting base 1. These two grooves together form the motion path of the internal transmission mechanism. An external threaded rod 10 is horizontally arranged at the center of the inner cavity of the mounting base 1, and an internal threaded hole 11 matching the external threaded rod 10 is arranged at the center of the left side of the mounting base 1. A rotating handle 12 is connected to the left side of the external threaded rod 10 through the internal threaded hole 11. By rotating the rotating handle 12, the external threaded rod 10 can be driven to move axially. Connecting blocks 14 are arranged at the center of the left and right sides of the bottom of the slider 5, and the bottom of the connecting blocks 14 extends through the connecting groove 8 and the slot 9 into the inner cavity of the mounting base 1. An internal threaded hole 15 matching the external threaded rod 10 is horizontally arranged on the connecting blocks 14, thereby realizing threaded transmission and allowing the sliding baffle seat 4 to be adjusted in position along the direction of the guide groove 3.

[0027] Preferably, the top four sides of the mounting base 1 are provided with vertically penetrating mounting holes 2, which facilitates the secure installation of the mounting base 1 on the equipment or frame. The surfaces of the mounting base 1 and the sliding baffle seat 4 are provided with reinforcing ribs to significantly improve the mechanical strength and deformation resistance of the overall structure.

[0028] Preferably, a bearing 13 is provided at the center of the right side of the inner cavity of the mounting base 1, and the outer ring of the bearing 13 is fixedly connected to the center of the right side of the inner cavity of the mounting base 1.

The length of the guide groove 3 from left to right is the same as the length of the mounting base 1 from left to right, so that the lengths are consistent, making the appearance neat and the functions coordinated. Example 2:

[0031] Reference Figure 1-3This embodiment differs from the first embodiment in that: the width of the connecting groove 8 and the slot 9 are the same, and buffer rubber pads are provided on both the left and right sides of the inner cavity of the connecting groove 8 and the slot 9. These buffer rubber pads can effectively absorb the impact and vibration during the movement, reduce noise and improve the service life of the components; the front and rear end faces of the connecting block 14 are closely connected to the front and rear end faces of the inner cavity of the connecting groove 8 and the slot 9, reducing shaking and swaying, and making the movement more precise. A three-millimeter gap is provided between the bottom of the connecting block 14 and the bottom of the inner cavity of the mounting base 1.
