[0002] The photoelectric switch reflection sheet is a special reflection sheet, usually with high reflection performance, used to reflect light signals. Its function is to enhance the detection and control capabilities of the photoelectric switch system. By reflecting light, the effective triggering and signal transmission of the switch are realized. The photoelectric switch reflection sheet is widely used in fields such as automated production lines, industrial equipment, security systems, and elevators.

[0003] In the prior art, it is necessary to evenly apply glue on the surface of the reflection sheet. Since the glue will change in performance due to temperature changes after being stored for a long time, the adhesion degree of the glue is affected, reducing the use effect of the automatic glue pasting of the photoelectric switch reflection sheet.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1 - 4 shown, the present invention provides an automatic glue pasting device for an optoelectronic switch reflection sheet, including a heating mechanism 1, and a limiting mechanism 2 is in contact with one side of the outer wall of the heating mechanism 1;

[0026] The heating mechanism 1 includes a heating chamber 101. A cover plate 102 is placed on the top of the heating chamber 101. A controller 103 is fixedly installed on the top of the cover plate 102. A forward and reverse motor 104 is fixedly installed on the bottom of the inner wall of the heating chamber 101. A lead screw 105 is fixedly installed on the bottom of the inner wall of the heating chamber 101. A moving plate 106 is threadedly connected to the outer surface of the lead screw 105. Two heaters 107 are fixedly installed on the top of the moving plate 106. A glue filling barrel 108 is fixedly installed on the top of the cover plate 102. A temperature sensor 109 is fixedly installed on one side of the outer wall of the glue filling barrel 108. One side of the outer wall of the controller 103 is electrically connected to the outer surface of the temperature sensor 109. A round hole 110 is opened on the top of the cover plate 102. A limiting plate 111 is fixedly installed on the bottom of the inner wall of the heating chamber 101. The outer surface of the lead screw 105 is movably inserted into the inside of the limiting plate 111. Two strip-shaped grooves 112 are opened on the inner surface of the inner wall of the heating chamber 101. Strip-shaped sliders 113 are movably embedded in the inner surfaces of the two strip-shaped grooves 112. One side of the outer walls of the two strip-shaped sliders 113 is fixedly connected to the outer surface of the moving plate 106. A glue outlet pipe 114 is fixedly penetrated through one side of the outer wall of the glue filling barrel 108. The input end of the glue outlet pipe 114 is communicated with the inside of the glue filling barrel 108. An electromagnetic valve 115 is fixedly installed on the outer surface of the glue outlet pipe 114.

[0027] The effect achieved by the entire Example 1 is as follows. First, due to the action of the temperature sensor 109, when it is detected that the temperature of the glue is not suitable, the forward and reverse motor 104 is started through the controller 103. Since one end of the lead screw 105 rotates inside the limiting plate 111, and the strip-shaped sliders 113 installed on both sides of the moving plate 106 are movably embedded inside the two strip-shaped grooves 112, the moving plate 106 can move back and forth stably on the lead screw 105, causing the two heaters 107 to move back and forth, and uniformly heating multiple areas at the bottom of the glue filling barrel 108 through the round hole 110. When the temperature of the internal glue returns to the normal value, the electromagnetic valve 115 is opened through the controller 103, so that the glue therein flows along the glue outlet pipe 114 to stick the glue to the reflector. After a certain period of time, the electromagnetic valve 115 is closed through the controller 103, thereby ensuring uniform glue sticking on the reflector and having the effect of automatic glue sticking, improving the use effect of the automatic glue sticking device for the reflector of the photoelectric switch.

[0028] Example 2, as Figures 2 - 4 shown, the limiting mechanism 2 includes a reciprocating conveying device 201. Two L-shaped plates 202 are fixedly installed on the top of the reciprocating conveying device 201. Electric push rods 203 are fixedly installed on the top of the inner walls of the two L-shaped plates 202. Limiting strips 204 are fixedly installed at the output ends of the two electric push rods 203. One side of the outer wall of the heating chamber 101 is in contact with the opposite side of the outer wall of the reciprocating conveying device 201.

[0029] The effect achieved by the entire Embodiment 2 is that when the reflector is placed on the reciprocating conveyor device 201, where the reciprocating conveyor device 201 is a conveyor belt device that can move back and forth in one direction without a full 360° flip. Then, two electric push rods 203 are activated to drive two limit bars 204 to move downward and limit the reflector on the reciprocating conveyor device 201. Then, uniform gluing is performed to ensure that the glue is accurately sprayed on the designated area of the reflector, further improving the usage effect of the automatic gluing device for the photoelectric switch reflector.

[0030] Working principle: First, place the reflector to be glued on the reciprocating conveyor device 201. Activate two electric push rods 203 so that two limit bars 204 limit the reflector on the reciprocating conveyor device 201. Then, monitor the temperature of the glue through the temperature sensor 109. When the temperature is not within the set range, start the forward and reverse motor 104 through the controller 103 to drive the moving plate 106 to move back and forth on the lead screw 105, causing the two heaters 107 to evenly heat the bottom of the glue filling barrel 108 until the glue returns to the normal temperature. Then, open the solenoid valve 115 through the controller 103 to evenly apply the glue along the glue outlet pipe 114 onto the reflector. After a certain period of time, close the solenoid valve 115 through the controller 103 to ensure that the glue is accurately sprayed on the designated area of the reflector. The entire process has the function of automatic gluing and ensures that the viscosity of the glue used each time is qualified, thereby improving the usage effect of the automatic gluing device for the photoelectric switch reflector.

[0031] The above are only the preferred embodiments of the present invention and do not limit the present invention in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
