[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, a front-end detection device for a stretching mold comprises two rollers 3, the outer surfaces of the two rollers 3 are commonly wound and connected with a conveyor belt 2, the left and right ends of the conveyor belt 2 are fixedly connected with a fixing ring 5, the lower parts of the outer surfaces of the two fixing rings 5 ​​are slidably connected with a support rod 6, the left and right ends of the two rollers 3 are rotatably connected with a support plate 4, the left end of one of the rollers 3 is fixedly connected with a motor 1, the motor 1 passes through the support plate 4 on the same side through a coupling at the output end and extends to the left end of the roller 3 on the same side and is rotatably connected to the support plate 4, a U-shaped frame 7 is provided on the rear side of the upper end of the conveyor belt 2, the middle part of the lower end of the U-shaped frame 7 is fixedly connected with an infrared sensor, and a feeding assembly 8 and a feeding assembly 9 are sequentially provided on the rear side of the outer surface of the conveyor belt 2.

[0027] In the specific implementation process of this scheme, first, the undetected material plate 91 is placed inside the feeding component 9, the feeding component 9 is started to supplement the material plate 91 that the feeding component 8 is about to transport, and then the feeding component 8 is started to supplement the material plate 91 at the upper rear end of the conveyor belt 2. During this process, the starting motor 1 uses two rollers 3 to drive the conveyor belt 2 to rotate. When the material plate 91 passes through the lower part of the lower end of the U-shaped frame 7, the infrared sensor at the lower end of the U-shaped frame 7 is used to measure the size of the material plate 91. If it exceeds the error range, the two flashing lights 51 on the same side will immediately flash red to remind the staff to remove it. When the material plate 91 is located at the front of the upper end of the conveyor belt 2, it will immediately fall on the machine of the next process and prepare for the next processing operation.

[0028] Specifically, in order to filter out unqualified material blocks 91, refer to Figure 2 , a plurality of equally spaced baffles 21 are fixedly connected to the outer surface of the conveyor belt 2;

[0029] For further information, see Figure 2, the ends of the two fixing rings 5 ​​close to each other are fixedly connected with flashing lights 51 penetrating the fixing rings 5 ​​on the same side, and the flashing lights 51 are placed between two adjacent baffles 21;

[0030] The above-mentioned mid-infrared sensor is used to measure the size of the material plate 91, mainly using the infrared sensor to measure the distance from the surface of the material plate 91 to the sensor, and converting these distance data into size information;

[0031] Infrared material size detection is mainly based on the physical properties of infrared rays, that is, objects emit infrared rays when they are exposed to thermal radiation. Infrared sensors measure the distance from the surface of the object to the sensor by receiving these infrared rays and converting them into electrical signals. Since the temperature difference between different objects or different parts of the same object will cause different infrared intensities, the size information of the object can be determined by detecting and analyzing these infrared signals.

[0032] The working process is to first emit infrared beams, which will be projected onto the surface of the material to be measured. When the infrared beams encounter the surface of the material, part of the infrared rays will be reflected back. The infrared sensor will receive these reflected infrared rays. By analyzing the received infrared signals, the device can calculate the time difference or phase difference from the emission to the reflection of the infrared rays. Based on this information, the device can calculate the distance from the surface of the material to the sensor. By measuring the distance of multiple points on the surface of the material, the shape and size of the material can be constructed.

[0033] It should be noted that although infrared detection of material size has the advantages of non-contact and rapid measurement, its accuracy may be affected by many factors, such as ambient temperature, air humidity, light, etc. Therefore, when measuring, the stability of the measurement environment should be maintained as much as possible to avoid these factors from interfering with the measurement results;

[0034] In addition, for different materials and measurement requirements, it may be necessary to select different types of infrared measurement equipment or adjust the measurement parameters. Therefore, in practical applications, it is necessary to select and adjust according to the specific situation.

[0035] It can be seen that first, the motor 1 is started to drive the roller 3 on the same side to rotate, and the conveyor belt 2 can be used to drive the roller 3 on the other side to rotate, so that the conveyor belt 2 wrapped around its surface also starts to rotate, and the material plate 91 placed on the rear side of the upper end of the conveyor belt 2 can be driven to transport it to the front side. When the material plate 91 passes through the infrared sensor at the lower end of the U-shaped frame 7, the specific size of the material plate 91 is measured by the infrared sensor. If the error is within the range, the device does not respond. If the error exceeds the specified range, the flashing lights 51 on the left and right sides of the material plate 91 will immediately receive the information from the infrared sensor and start flashing red lights to remind the staff to remove it. In addition, in the process of transporting the material plate 91, the baffle 21 is used to separate the material plate 91 to facilitate the search for the material plate 91 that does not meet the standards.

[0036] Specifically, in order to further improve the efficiency of detection, see Figure 3 , Figure 4 and Figure 5 The feeding assembly 8 includes a fixed column 82, a plurality of L-shaped rods 81 are fixedly connected to the outer surface of the fixed column 82 in a circular array, the lower ends of the plurality of L-shaped rods 81 are fixedly connected to suction cups, the lower end of the fixed column 82 is fixedly connected to two mutually meshing gears 83, the lower end of the gear 83 located at the front is rotatably connected to a telescopic frame 84, and the lower end of the gear 83 located at the rear is fixedly connected to a motor 2 85;

[0037] For further information, see Figure 4 , the motor 2 85 passes through the telescopic frame 84 through the coupling at the output end and extends to the lower end of the gear 83 on the same side and is rotatably connected to the telescopic frame 84 , and the motor 2 85 is fixedly connected to the telescopic frame 84 through the connecting seat;

[0038] For further information, see Figure 3 and Figure 5 The feeding component 9 includes a receiving platform 94, a driving component 95 is provided at the rear of the upper end of the receiving platform 94, a limiting rod 93 is fixedly connected to the right front of the driving component 95, a material plate 91 is provided at the middle side of the front of the upper end of the receiving platform 94, the inside of the driving component 95 and the upper part of the outer surface of the conveyor belt 2, and a limiting block 92 is provided at the rear side of the front end of the material plate 91 located at the front of the upper end of the receiving platform 94, and the limiting block 92 and the limiting rod 93 are fixedly connected to the receiving platform 94;

[0039] For further information, see Figure 5 The driving assembly 95 includes a containing frame 951, a push rod 952 is slidably connected to the middle side of the upper rear end of the receiving platform 94, and an electric telescopic rod 953 is fixedly connected to the rear end of the push rod 952;

[0040] For further information, see Figure 5 , the limiting rod 93 is fixedly connected to the holding rack 951, a plurality of material plates 91 are placed inside the holding rack 951, and the holding rack 951 is fixedly connected to the receiving platform 94;

[0041] The horizontal height of the push rod 952 is equal to the thickness of a material plate 91, so that after the push rod 952 pushes the lowermost material plate 91 to the front, it can support several material plates 91 located at the upper part, so that the push rod 952 can be smoothly reset.

[0042] The specific shape, size and structure of the above-mentioned holding rack 951 only need to be able to stack a number of material panels 91 so that the lowest material panel 91 can slide smoothly.

[0043] It can be seen that first, the electric telescopic rod 953 is started to push the push rod 952 to slide on the upper end of the receiving platform 94, so as to push the material plate 91 at the lower side to the front position of the upper end of the receiving platform 94. In the process of pushing away from the containing rack 951, the limit rod 93 and the limit block 92 are used to limit the pushed material plate 91 to prevent its displacement from affecting the loading of the loading assembly 8. After the material plate 91 at the front is in the middle of the front of the upper end of the receiving platform 94, the electric telescopic rod 953 drives the push rod 95 2 reset, at this time, the lower parts of several material plates 91 inside the holding rack 951 are not supported, and under the action of their own gravity, the material plate 91 at the bottom will be close to the receiving platform 94 again, which is convenient for the next reset of the electric telescopic rod 953. After the loading assembly 8 transports the material plate 91 on the front side, the electric telescopic rod 953 pushes the push rod 952 again to push the material plate 91 at the bottom at this time, so as to supplement the material plate 91 at the position where the loading assembly 8 needs to transport, and the operation is cyclical;

[0044] After the motor 2 85 is started, the gear 83 on the same side is driven to rotate. Under the action of the other gear 83, the fixed column 82 is driven to rotate, which can drive the L-shaped rod 81 to rotate. When the L-shaped rod 81 is placed on the upper end of the material plate 91 at the front of the upper end of the receiving platform 94, the telescopic frame 84 is used to drive a number of L-shaped rods 81 to descend, so that the suction cup is in close contact with the material plate 91, and the material plate 91 is adsorbed by the suction cup, and then the several L-shaped rods 81 are driven to move upward to reset, and then rotated and transported to the upper rear side of the outer surface of the conveyor belt 2. When the L-shaped rod 81 descends, the suction cup located at the upper end of the conveyor belt 2 releases the adsorption of the suction cup, and the material plate 91 is placed on the upper end of the conveyor belt 2 and placed between the two baffles 21. In this way, the material plate 91 at the front of the upper end of the receiving platform 94 is repeatedly transported to the upper rear side of the outer surface of the conveyor belt 2, completing autonomous loading and accelerating the efficiency of detection.

[0045] The suction cups mentioned above are all made of soft rubber or silicone, and have many dense small holes on the surface. When the suction cup is in close contact with the surface of the material plate 91, a sealed space is formed between these small holes and the surface of the object. Through some means (such as manual squeezing or mechanical device), the air in the space behind the suction cup is discharged, so that the air pressure inside the suction cup is lower than the external atmospheric pressure.

[0046] According to the principle of air pressure balance, the higher external atmospheric pressure will press the object tightly against the suction cup, thus generating a larger adsorption force. This adsorption force is enough to resist the object's own weight and firmly fix the object on the suction cup.

[0047] The above-mentioned middle telescopic frame 84 is composed of an electric telescopic rod and two support plates. The lower support plate is fixedly connected to the motor 2 85, and the upper support plate is rotationally connected to the two gears 83. The support plate located at the lower part is connected to the electric telescopic rod. Starting the electric telescopic rod can drive the other components on the upper part of the two support plates to move up and down.

[0048] It should be noted that the specific installation method, circuit connection method and control method of the motor 1, electric telescopic rod 953, L-shaped rod 81 and motor 2 85 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0049] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
