[0002] Photoelectric sensors are sensors that convert light signals into electrical signals using the principle of the photoelectric effect. These sensors are widely used in industrial automation, security systems, consumer electronics and other fields. Photoelectric sensors are generally composed of a light-emitting part and a receiving part. They detect objects or determine their positions by detecting the intensity, changes or a certain wavelength of light. Traditional photoelectric sensors are fixed on a bracket, and the sensor for the light-emitting part and the sensor for the receiving part need to be set relative to each other in order for the two photoelectric sensors to work properly.

[0030] like Figure 5-7 This example can facilitate the determination of whether an object passes between the two sensor bodies 102.

[0031] Since the photoelectric sensor includes a sphere 101, a sensor body 102 is bonded to the sphere 101, two sliders 206 are welded to the gantry 201, and ball grooves 205 are provided on the opposite surfaces of the two sliders 206. The sphere 101 is rotatably connected between the two ball grooves 205, and the sphere 101 is restricted between the two sliders 206 by the two ball grooves 205 on the two sliders 206, so that the sphere 101 can be arbitrarily rotated between the two sliders 206 to adjust the emission direction of the sensor body 102. Two groups of sensor bodies 102 are provided to facilitate the relative adjustment of the two groups of sensor bodies 102. One of the two sensor bodies 102 is responsible for emission and the other is responsible for reception. Therefore, when the two sensor bodies 102 are blocked by an object, the other sensor body 102 cannot receive the emitted light, which facilitates the judgment of whether there is an object passing between the two sensor bodies 102.

[0032] like Figure 6-7 As shown, this example can achieve the effect that the position of the ball 101 can be fixed when it rotates to any position.

[0033] Since a bracket 202 is welded to the middle part of the gantry 201, a pressure column 203 is vertically slidably connected to the bracket 202, and an arc block 204 is welded to the lower end of the pressure column 203. The arc block 204 is pressed on the upper side of the ball 101, and a compression spring is sleeved on the pressure column 203. The compression spring is located between the bracket 202 and the arc block 204. The compression spring applies downward pressure to the arc block 204 and the pressure column 203, so that the arc block 204 is pressed on the upper side of the ball 101, so that the position of the ball 101 can be fixed when it rotates to any position.

[0034] like Figure 6-9 As shown, this example can achieve the effect of adjusting the height of the sphere 101.

[0035] Since the outer sides of the two sliders 206 are provided with sliding grooves 207 and the vertical plate 303 is provided with a notch 302, the two sliders 206 are respectively slidably connected to the two sides of the notch 302 through the notches 302 thereon. The two sliders 206 can slide vertically at the notches 302 to adjust the height of the ball 101 and the sensor body 102, so that the two sensor bodies 102 are easier to align.

[0036] like Figure 6-7 As shown, this example can achieve the effect that the heights of the two sliders 206 can be fixed when they slide to any positions at the slot 302 .

[0037] Since a bracket 210 is welded to the front side of the gantry 201, a pressure column 209 is slidably connected to the bracket 210, a plane block 208 is welded to the end of the pressure column 209, the plane block 208 is pressed on the front side of the vertical plate 303, and a compression spring is sleeved on the pressure column 209. The compression spring is located between the plane block 208 and the bracket 210. The compression spring gives elastic force to the plane block 208 and the pressure column 209, so that the plane block 208 can always be pressed on the front side of the vertical plate 303, thereby making the height of the two sliders 206 when sliding to any position at the slot 302 can be fixed.

[0038] like Figure 8-9 As shown, this example can achieve the effect of adjusting the front and rear positions of the vertical plate 303, the two sliders 206, the ball 101 and the sensor body 102.

[0039] Since a slide 305 is welded to the lower end of the vertical plate 303, a track 309 is provided on the bottom film 301, the slide 305 is slidably connected to the track 309, a pressure strip 306 is pressed on the upper side of the slide 305, and guide posts 307 are welded to the front and rear ends of the pressure strip 306, and the two guide posts 307 are respectively vertically slidably connected to the front and rear ends of the bottom film 301, and the lower ends of the two guide posts 307 are welded to round pieces 308, and a compression spring is sleeved on the guide posts 307, and the compression spring is located between the bottom film 301 and the round piece 308. The slide 305 can move forward and backward on the track 309, thereby adjusting the front and rear positions of the vertical plate 303, the two sliders 206, the ball 101 and the sensor body 102, so that the two sensor bodies 102 are easier to align. The compression springs on the two guide posts 307 always exert downward force on the two discs 308, so that the two guide posts 307 and the pressure strip 306 always tend to move downward, so that the pressure strip 306 always presses on the slide 305, thereby allowing the slide 305 to be fixed when it moves to any position on the track 309.

[0040] like Figure 8-9 As shown, this example can achieve the effect of fixing the bottom film 301 at the required position.

[0041] Since two connecting strips 304 are fixed on the bottom film 301, and round holes are provided on the two connecting strips 304, screws can be inserted into the round holes, so that the two connecting strips 304 are fixed at the required positions, and the bottom film 301 is fixed at the required position. At this time, the sensor body 102 located on the bottom film 301 can adjust the position in multiple directions, so that the two sensor bodies 102 can be easily aligned.

[0042] like Figure 8-11 As shown, this example can achieve the effect of conveniently adjusting the distance between the two spheres 101 and the two sensor bodies 102 .

[0043] Since two films 301 are provided, cross bars 310 are welded on the opposite surfaces of the two films 301, and the two cross bars 310 are respectively slidably connected to the two ends of the hollow rod 405, and the two ends of the hollow rod 405 are threadedly connected with fastening screws 1 404, and the two fastening screws 1 404 are respectively pressed on the two cross bars 310. In order to set the two films 301 relative to each other as much as possible, the cross bars 310 on the two films 301 are respectively inserted into the two ends of the hollow rod 405, so that the two films 301 can be set relative to each other, and the balls 101 and the sensor bodies 102 on the upper sides of the two films 301 can be easily set relative to each other. The two cross bars 310 can slide left and right along the hollow rod 405, thereby adjusting the spacing between the two films 301, and then facilitating the adjustment of the spacing between the two balls 101 and the two sensor bodies 102. The cross bars 310 can be fixed on the hollow rod 405 by rotating the fastening screws 1 404.

[0044] like Figure 10-11 As shown, this example can achieve the effect of enabling the two sensor bodies 102 to meet more usage scenarios when in use.

[0045] Since cylinders 406 are welded to the left and right ends of the upper side of the hollow rod 405, each cylinder 406 is plugged with a vertical shaft 402, and plane mirrors 401 are fixed to the upper ends of the two vertical shafts 402, and a gear 403 is fixed to the lower ends of the vertical shafts 402, and a ring groove 407 is provided on the gear 403, the vertical shaft 402 can be inserted into the cylinder 406, and then the vertical shaft 402 is rotated and connected to the hollow rod 405, then the angles of the two plane mirrors 401 can be adjusted, and then the light emitted by the two sensor bodies 102 can be reflected, and the light emitted by the two sensor bodies 102 can be reflected to the required position, and then received by a sensor arranged outside, so that the two sensor bodies 102 can meet more usage conditions when in use.

[0046] like Figure 10-11 As shown, this example can achieve the effect of precisely adjusting the slow rotation of the plane mirror 401.

[0047] Since two sliding sleeves 501 are slidably connected to the empty rod 405, each sliding sleeve 501 is threadedly connected with a fastening screw 3 506, and the fastening screw 3 506 is pressed on the empty rod 405. The upper part of the sliding sleeve 501 is rotatably connected with a short shaft 502 through a bearing seat. A gear 2 504 is welded on the upper end of the short shaft 502. The gear 2 504 can be inserted into the corresponding annular groove 407. A rotating head 505 is fixed on the upper side of the gear 2 504. A fastening screw 2 503 is threadedly connected to the sliding sleeve 501. The fastening screw 2 503 is pressed on the corresponding short shaft 502. The two sliding sleeves 501 can slide left and right on the empty rod 405. The sliding sleeve 501 can be fixed on the rotating head 505 by rotating the fastening screw 3 506, thereby adjusting the two gears. The left and right positions of the gears 2 504 make the two gears 2 504 mesh with the two gears 1 403 respectively, and then the rotary head 505 can be rotated to drive the gear 2 504 to rotate through the short shaft 502, and then the larger gear 1 403 can be driven to rotate through the smaller gear 2 504, so that it is easier to precisely adjust the rotation of the gear 1 403, the vertical shaft 402 and the plane mirror 401, and then precisely adjust the slow rotation of the plane mirror 401. The teeth of the gear 1 403 are set in the annular groove 407. When the gear 2 504 is inserted into the annular groove 407 on the gear 1 403, the gear 1 403 can be prevented from moving upward, and then the vertical shaft 402 and the plane mirror 401 can be prevented from moving upward, and then the vertical shaft 402 can be prevented from detaching from the cylinder 406. The gear 2 504 can be fixed by rotating the fastening screw 2 503 to press on the short shaft 502, and then the gear 1 403, the vertical shaft 402 and the plane mirror 401 can be fixed.

[0049] S1: Insert the sensor body 102 onto the ball 101;

[0050] S2: Processing ball grooves 205 corresponding to the ball 101 on the two sliders 206, and installing the ball 101 between the two ball grooves 205;
