Description

TECHNICAL FIELD

[0001] The utility model relates to optical lens processing technical field, in particular to a lens packaging device. BACKGROUND

[0002] In modern optical industry, optical lenses are widely used in many fields such as photographic and video equipment, medical optical instruments, glasses and various types of precision optical detection devices. With the increasing demand for optical lenses in various industries and the increasingly stringent quality requirements, the production process of optical lenses is continuously innovated and optimized. Among them, lens packaging is a very key link in the production process, and its importance is increasingly prominent.

[0003] In the traditional lens packaging operation process, a bagging machine is often used to perform the lens packaging task. In the general operation process, the bagging machine first loads the lens into the packaging bag, and then transports it to a specific position, and the sealing mechanism completes the sealing process of the open end. For example, in the case of a common horizontal bagging machine, when the packaging bag moves to the end along the horizontal conveying track, the sealing device above or below will use heat sealing, ultrasonic sealing and other methods to seal. However, this traditional method is inefficient and time-consuming in the conveying link, and during the movement of the packaging bag to the end, there is a risk of dust entering the bag and contaminating the lens, affecting the optical performance and cleanliness of the lens.

[0004] Therefore, we propose a lens packaging device. UTILITY MODEL CONTENT

[0011] In a further technical solution, the support is fixedly connected with a temperature sensor at a side away from the baffle, and the sensing end of the temperature sensor extends to the inside of the hot pressing plate through the hot pressing plate.

[0012] The beneficial effects of the present application are as follows:

[0023] The embodiment of the utility model is further explained below in combination with the drawings. Embodiment

[0024] As Figures 1-6 Indicated, a lens packaging device, including conveying belt and the support frame at conveying belt one side, the surface of conveying belt is equidistant and is provided with packing bag, the surface of support frame is fixedly connected with hydraulic machine 1, the telescopic end bottom of hydraulic machine 1 is fixedly connected with fixed plate 2, the surface of fixed plate 2 is fixedly connected with air pipe limiting plate 3, and pneumatic chuck 4 is arranged on air pipe limiting plate 3, and air pipe limiting plate 3 is detachably connected with support strip 5 at the end in the advancing direction of conveying belt, and the end of support strip 5 is fixedly connected with symmetrical support 6, and the bottom surface of support 6 is fixedly connected with hot pressing plate 7, and hot pressing plate 7 is hollow, and the inner wall bottom surface of hot pressing plate 7 is provided with equidistant recess 8, and the inner wall of each recess 8 is fixedly connected with heating wire 9, and one side of support 6 is provided with limiting mechanism for pressing down packing bag opening, and the side surface of support 6 away from baffle 10 is fixedly connected with temperature sensor 17, and the sensing end of temperature sensor 17 extends to the inside of hot pressing plate 7 through hot pressing plate 7.

[0025] In another embodiment, as Figures 1-4 Indicated, limiting mechanism includes the baffle 10 fixed on the surface of support strip 5, and the baffle 10 is opposite to support 6, and the bottom surface of baffle 10 is open, and the bottom opening of baffle 10 is inserted with pressing block 11, and the bottom surface of pressing block 11 is flush with the bottom surface of hot pressing plate 7, and the top surface of pressing block 11 is fixedly connected with spring 12 between the inner wall of baffle 10.

[0026] The structure can make limiting mechanism and hot pressing plate 7 synchronous and keep synchronous pressing on the surface of packing bag, but when separating, pressing block 11 can keep pressing on the surface of packing bag opening, to avoid the influence of heat preheating on lens.

[0027] In another embodiment, as Figure 2 And Figure 3As shown, the support strip 5 is fixedly connected with the plug plate 14 at one end close to the trachea limiting plate 3, the side wall of the trachea limiting plate 3 is provided with the socket 13, and the top surface of the trachea limiting plate 3 and the top surface of the plug plate 14 are provided with the threaded hole 15, and the inner wall of the threaded hole 15 is threadedly connected with the bolt 16 inserted from the top of the trachea limiting plate 3.

[0028] By setting the support strip 5 and the trachea limiting plate 3 to be threadedly connected, the installation and disassembly can be facilitated, the storage after use can be facilitated, and the staff can be prevented from being scalded by residual heat when not in use.

[0029] In another embodiment, the bottom end side wall of the hot pressing plate 7 is made of ceramic fiber material, the bottom surface of the hot pressing plate 7 is made of aluminum alloy material, and the thickness of the bottom surface of the hot pressing plate 7 is 5-10 mm.

[0030] By limiting the material of the bottom of the hot pressing plate 7, the bottom surface of the hot pressing plate 7 can quickly conduct heat during use, and the ceramic fiber material can prevent the bottom heat from flowing out too quickly, thereby ensuring the practicality of the device.

[0031] In operation, the staff places a plurality of packaging bags at equal intervals on the surface of the conveyor belt, starts the conveyor belt to run slowly, and starts the hydraulic machine 1, the heating wire 9, the temperature sensor 17 and other equipment to ensure that they are in normal working condition. The telescopic end of the hydraulic machine 1 is started to drive the fixed plate 2, the trachea limiting plate 3 and the pneumatic suction cup 4 to move downward. In the moving process, the pneumatic suction cup 4 opens the opening of the packaging bag by using negative pressure. Then, the material conveying part of the bagging machine puts the optical glass into the packaging bag. Then, the telescopic end of the hydraulic machine 1 rises. At this time, the conveyor belt conveys the packaging bag with the optical glass to the front by one station. The telescopic end of the hydraulic machine 1 descends again to repeat the above operation. At the same time, the packaging bag with the optical glass moves to the position directly below the hot pressing plate 7. The telescopic end of the hydraulic machine 1 drives the trachea limiting plate 3 to move downward, thereby synchronously moving the support strip 5, the symmetrical support 6 and the hot pressing plate 7 downward. Before the hot pressing plate 7 contacts the opening of the packaging bag, the pressing block 11 in the limiting mechanism contacts the packaging bag under the action of the spring 12. As the hot pressing plate 7 continues to move downward, the pressing block 11 compresses the spring 12 until the bottom surface of the hot pressing plate 7 and the bottom surface of the pressing block 11 jointly press the opening of the packaging bag, thereby separating the lens from the hot pressing plate 7. The heating wire 9 is powered on to heat the hot pressing plate 7. The bottom surface of the hot pressing plate 7 made of aluminum alloy material quickly conducts heat to heat and seal the opening of the packaging bag. The temperature sensor 17 monitors the temperature inside the hot pressing plate 7 in real time to control the power of the heating wire 9. Then, the telescopic end of the hydraulic machine 1 rises, and the hot pressing plate 7 and the limiting mechanism move upward. The spring 12 rebounds, and the pressing block 11 continues to press the surface of the sealing portion of the packaging bag for a period of time to ensure that the sealing portion is cooled and shaped.

[0032] The above embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
