Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric switches, in particular to an opposed type micro photoelectric switch. Background Technique

[0002] The opposed type micro photoelectric switch is a sensor that works based on the principle of the photoelectric effect, mainly composed of two parts: a transmitter and a receiver. The transmitter emits light. When these lights are blocked or reflected by the object to be detected, the intensity of the light received by the receiver changes, thereby outputting a corresponding electrical signal to realize the detection of the presence or absence of the object.

[0003] After retrieval, during the installation process of the existing opposed type micro photoelectric switch, there is no alignment, resulting in the receiver and the transmitter being uneven horizontally after installation, which in turn affects the detection accuracy. At the same time, the sizes of the objects to be detected in different scenarios vary, and it is inconvenient when passing between the receiver and the transmitter.

[0004] Therefore, those skilled in the art have provided an opposed type micro photoelectric switch to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the content of the utility model is to solve the disadvantages existing in the prior art, and an opposed type micro photoelectric switch is proposed. This photoelectric switch has high stability, strong detection accuracy, and is applicable to different environments and scenarios, thereby improving the accuracy and applicability of this photoelectric switch.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An opposed type micro photoelectric switch, including a receiver and a transmitter. A balancing mechanism is provided at the lower ends of both the receiver and the transmitter. Both of the balancing mechanisms are slidably arranged on an adjusting mechanism. Connecting lines are fixedly provided at one sides of the lower ends of both the receiver and the transmitter. Switches are provided at the upper ends of both the receiver and the transmitter;

[0008] The balancing mechanism includes a horizontal plate and a positioning block. The number of the horizontal plates and the positioning blocks is two. Both of the horizontal plates are detachably arranged at the lower ends of the receiver and the transmitter. Both of the positioning blocks are fixedly arranged at the lower ends of the receiver and the transmitter. Positioning grooves are opened at one sides of both of the horizontal plates close to the clamping plates. Positioning plates are fixedly provided at one sides of both of the positioning blocks. Screw holes are opened on both of the positioning plates and the horizontal plates. Fixing bolts are threadedly arranged at the upper ends of both of the positioning plates at corresponding screw holes;

[0009] Through the above technical solution, the receiver and the transmitter can be kept horizontal and stable with respect to each other during the installation process by means of a balancing mechanism, thereby ensuring that the emission source can be accurately received by the reception source. By placing the receiver and the transmitter on their respective horizontal plates, the positioning blocks are pushed while being in close contact with the horizontal plates under the action of the clamping plates and the springs, so that the positioning plates extend into the positioning grooves, and the receiver and the transmitter are fixed to their respective horizontal plates by using fixing bolts, thereby improving the detection accuracy of the optoelectronic switch.

[0010] Further, the adjusting mechanism includes a track, a motor, and sliders. The track is fixedly arranged at the lower ends of the receiver and the transmitter. The motor is fixedly arranged on one side of the track. A bidirectional screw is fixedly connected to the output end of the motor and located inside the track. The number of the sliders is two, and both of the two sliders are fixedly arranged at the lower ends of the corresponding horizontal plates. A chute is formed at the upper end of the track, and threaded sleeves are fixedly arranged at the lower ends of both of the two sliders;

[0011] Through the above technical solution, the distance between the receiver and the transmitter can be adjusted by means of the adjusting mechanism, and thus objects of different sizes can be detected. By the rotation of the bidirectional screw under the action of the motor, the threaded sleeves move relatively on the bidirectional screw, and the sliders move in the chute, and thus the receiver and the transmitter can be driven to move relatively, thereby improving the applicability of the optoelectronic switch.

[0012] Further, a emission source is fixedly arranged at the upper end of one side of the transmitter, and a reception source is fixedly arranged at the upper end of one side of the receiver;

[0013] Through the above technical solution, the detection of the presence or absence of an object can be achieved by means of the emission source and the reception source.

[0014] Further, springs are fixedly arranged on one side of both of the two horizontal plates, and clamping plates are fixedly connected to one ends of both of the two springs and located on the horizontal plates;

[0015] Through the above technical solution, the positioning blocks can be pushed and positioned by the clamping plates fixedly connected to one ends of the springs and located on the horizontal plates.

[0016] Further, the two positioning plates are respectively inserted into the corresponding positioning grooves;

[0017] Through the above technical solution, the receiver and the transmitter can be kept horizontally aligned by inserting the positioning plates into the corresponding positioning grooves respectively.

[0018] Further, the two fixing bolts respectively penetrate through the corresponding screw holes and are threadedly connected to the horizontal plates;

[0019] Through the above technical solution, the fixing bolts respectively penetrate through the corresponding screw holes and are threadedly connected to the horizontal plate, ensuring the stable installation of the receiver and the transmitter and preventing the receiver and the transmitter from tilting and loosening on the horizontal plate.

[0020] Further, both of the two sliders slide inside the sliding grooves.

[0021] Through the above technical solution, since the sliders all slide inside the sliding grooves, the receiver and the transmitter can be unobstructed during the relative movement process.

[0022] Further, both of the two threaded sleeves slide on the bidirectional screw.

[0023] Through the above technical solution, since the threaded sleeves all slide on the bidirectional screw, the receiver and the transmitter can have an automatic adjustment function, thereby reducing manual operation and improving the accuracy of the adjusted distance.

[0024] The utility model has the following beneficial effects:

Through the balance mechanism, the receiver and the transmitter can be kept horizontal and stable with respect to each other during the installation process, thereby ensuring that the emission source can be accurately received by the receiving source. By placing the receiver and the transmitter on their respective horizontal plates, when the positioning blocks are close to the horizontal plates and are pushed by the clamping plates and the springs, the positioning plates extend into the positioning grooves, and the fixing bolts are used to fix the receiver and the transmitter on their respective horizontal plates, thus improving the detection accuracy of the photoelectric switch.

[0026] 2. A transmissive type miniature photoelectric switch proposed by the utility model. Through the adjustment mechanism, the distance between the receiver and the transmitter can be adjusted, and thus objects of different sizes can be detected. By the bidirectional screw rotating under the action of the motor, the threaded sleeves move relative to each other on the bidirectional screw, and the sliders move in the sliding grooves, and thus the receiver and the transmitter can be driven to move relative to each other, thereby improving the applicability of the photoelectric switch.

Obviously, the described specific implementation mode is only a part of the specific implementation modes of the present utility model, rather than all of them. Based on the specific implementation modes of the present utility model, all other specific implementation modes obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0036] Refer to Figure 1 、 3 -4, a specific implementation mode provided by the present utility model: A transmissive miniature photoelectric switch includes a receiver 1 and a transmitter 2. Balance mechanisms 3 are provided at the lower ends of both the receiver 1 and the transmitter 2. Both balance mechanisms 3 are slidably arranged on an adjustment mechanism 4.

Detection of the presence or absence of an object can be achieved through the emission source 7 and the receiving source 8;

[0037] The balancing mechanism 3 includes a horizontal plate 31 and positioning blocks 32. The number of the horizontal plate 31 and the positioning blocks 32 is two. The two horizontal plates 31 are detachably arranged at the lower ends of the receiver 1 and the transmitter 2. The two positioning blocks 32 are fixedly arranged at the lower ends of the receiver 1 and the transmitter 2. Positioning grooves 35 are formed on one sides of the two horizontal plates 31 close to the clamping plate 34. Positioning plates 36 are fixedly arranged on one sides of the two positioning blocks 32. Threaded holes 37 are formed on the two positioning plates 36 and the horizontal plate 31. Fixing bolts 38 are threadedly arranged at the upper ends of the two positioning plates 36 at corresponding threaded holes 37. Through the balancing mechanism 3, the receiver 1 and the transmitter 2 can be kept horizontal and stable with each other during the installation process, so as to ensure that the emission source 7 can be accurately received by the receiving source 8. By placing the receiver 1 and the transmitter 2 on their respective horizontal plates 31, when the positioning blocks 32 are close to the horizontal plates 31, they are pushed forward under the action of the clamping plate 34 and the spring 33, so that the positioning plates 36 extend into the positioning grooves 35, and the receiver 1 and the transmitter 2 are fixed on their respective horizontal plates 31 by using the fixing bolts 38, thereby improving the detection accuracy of the photoelectric switch. Springs 33 are fixedly arranged on one sides of the two horizontal plates 31. Clamping plates 34 are fixedly connected to one ends of the two springs 33 and located on the horizontal plates 31. By fixedly connecting the clamping plates 34 to one ends of the springs 33 and located on the horizontal plates 31, the positioning blocks 32 can be pushed and positioned. The two positioning plates 36 are respectively clamped into the corresponding positioning grooves 35. By respectively clamping the two positioning plates 36 into the corresponding positioning grooves 35, the receiver 1 and the transmitter 2 can be kept horizontally consistent. The two fixing bolts 38 respectively penetrate through the corresponding threaded holes 37 and are threadedly connected to the horizontal plate 31. By respectively penetrating through the corresponding threaded holes 37 and being threadedly connected to the horizontal plate 31, the fixing bolts 38 ensure the stable installation of the receiver 1 and the transmitter 2, and avoid the receiver 1 and the transmitter 2 from tilting and loosening on the horizontal plate 31.

[0038] Refer to Figure 1 、 2And 5, the adjusting mechanism 4 includes a rail 41, a motor 43 and a slider 45. The rail 41 is fixedly arranged at the lower ends of the receiver 1 and the transmitter 2.

Threaded sleeves 46 are fixedly arranged at the lower ends of both sliders 45. The distance between the receiver 1 and the transmitter 2 can be adjusted by the adjusting mechanism 4, and then objects of different sizes can be detected. By the bidirectional screw 44 rotating under the action of the motor 43, the threaded sleeves 46 move relatively on the bidirectional screw 44, and the sliders 45 move in the chute 42, and then the receiver 1 and the transmitter 2 can be driven to move relatively, thus improving the applicability of the photoelectric switch. Both sliders 45 slide inside the chute 42. By both sliders 45 sliding inside the chute 42, the receiver 1 and the transmitter 2 can be prevented from being obstructed during the relative movement. Both threaded sleeves 46 slide on the bidirectional screw 44. By both threaded sleeves 46 sliding on the bidirectional screw 44, the receiver 1 and the transmitter 2 can have an automatic adjustment function, thereby reducing manual operation and improving the accuracy of adjusting the distance.

[0039] Working principle: When the opposed type micro photoelectric switch is in use, first place the receiver 1 and the transmitter 2 on their respective horizontal plates 31. While the positioning block 32 is closely attached to the horizontal plate 31, it is pushed forward under the action of the clamping plate 34 and the spring 33, so that the positioning plate 36 extends into the positioning groove 35, and use the fixing bolt 38 to fix the receiver 1 and the transmitter 2 on their respective horizontal plates 31, thereby ensuring that the emission source 7 can be accurately received by the receiving source 8. Subsequently, the motor 43 can be started according to the size of the detected object, so that the bidirectional screw 44 rotates under the action of the motor 43, the threaded sleeves 46 move relatively on the bidirectional screw 44, and the sliders 45 move in the chute 42, and then the receiver 1 and the transmitter 2 can be driven to move relatively, and then the distance between the receiver 1 and the transmitter 2 can be adjusted to realize the detection of objects of different sizes, thus improving the accuracy and applicability of the photoelectric switch.
