Description

Technical Field

[0001] This utility model relates to the field of thermos cup production equipment, and in particular to an airtightness testing device for thermos cup production. Background Technology

[0002] As a daily necessity widely used in homes, offices, and outdoors, insulated cups have become an essential tool for consumers due to their excellent heat preservation performance. The core function of an insulated cup lies in the sealing of its inner and outer layers and vacuum insulation technology. However, to ensure that an insulated cup has ideal heat preservation effect and long-term reliability, airtightness is a crucial factor. In the production process of insulated cups, ensuring that the airtightness of each product meets the standards is one of the key links in production quality control. Insulated cups with unqualified airtightness may have a significant decrease in their heat preservation effect or even leakage, thereby affecting the user experience and market competitiveness of the product. Therefore, airtightness testing has become an important part of the insulated cup production process.

[0003] Traditionally, the production of insulated cups mostly involves workers manually placing each cup into a water tank and visually inspecting for bubbles. This method relies heavily on the operator's experience, is susceptible to human error, and carries the risk of missed or misjudged inspections. Furthermore, manual inspection is inefficient and cannot meet the needs of large-scale production. As a result, testing equipment has emerged. However, existing testing equipment requires the replacement of numerous parts to adapt to different sizes of insulated cups, which is relatively cumbersome and reduces work efficiency to some extent.

[0004] Therefore, in order to solve the problems existing in the above-mentioned technologies, an airtightness testing device for the production of thermos cups is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an airtightness testing device for thermos cup production. Through a shifting mechanism, an electric slider drives an electric telescopic rod to move within an electric slide rail. The telescopic rod is then lowered, positioning the upper end of the thermos cup's outer wall at the center of two clamping rings. A bidirectional hydraulic rod then retracts, securing the thermos cup firmly within the clamping rings before it is inserted into the container for airtightness testing. This effectively reduces manual labor, accommodates thermos cups of different sizes, and enables automated operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An airtightness testing device for thermos cup production includes a base plate. A plurality of fixing mechanisms are provided at the front end of the upper surface of the base plate. Each fixing mechanism includes a plurality of mounting grooves opened on the upper surface of the base plate. Each mounting groove is provided with a sliding rod. A damping spring is sleeved on one end of each sliding rod. A movable block is slidably attached to the other end of each sliding rod. A clamping strip is fixedly connected to the upper surface of each movable block.

[0008] The upper end of the fixing mechanism has a displacement mechanism, which includes an electric slide rail. An electric slider is slidably connected inside the electric slide rail. An electric telescopic rod is fixedly connected to the lower surface of the electric slider. A bidirectional hydraulic rod is fixedly connected to the output end of the electric telescopic rod. A movable frame is fixedly connected to the output end of each bidirectional hydraulic rod. Multiple mounting rods slide on the frame of each movable frame. A compression spring is sleeved on one side of each mounting rod. A clamping ring is fixedly connected to the ends of each mounting rod that are close to each other. A sealing mechanism is provided at the upper end of the base plate. Multiple mounting frames and a visual recognition camera are provided at the lower end of the sealing mechanism. Multiple tanks are provided at the upper part of the middle of the upper surface of the base plate.

[0009] Through the above technical solution, the design of this airtightness testing equipment combines stability, flexibility, automation, and high efficiency, which not only improves production efficiency but also ensures the accuracy and reliability of product quality testing.

[0010] Furthermore, multiple placement pads are fixedly connected to the front end of the upper surface of the base plate, and the mounting grooves are respectively set at the edge of the placement pads;

[0011] The above technical solution effectively reduces friction between the bottom of the thermos and the base plate by using a placement pad, thus avoiding scratches on the bottom of the thermos.

[0012] Furthermore, each of the four corners of the upper surface of the base plate is fixedly connected to a column, and each of the electric slide rails is fixedly connected to the outer wall of the column near the middle of the base plate. The sealing mechanism includes a support frame fixedly connected to the upper surface of the column.

[0013] The above technical solution allows for easier installation of other components via the installed columns, and effectively improves the overall stability of the equipment frame.

[0014] Furthermore, multiple cylinders are fixedly connected to the middle of the upper surface of the support frame, a miniature air pump is fixedly connected to the output end of the cylinder, a conical block is fixedly connected to the lower surface of the miniature air pump, an air vent is provided inside the conical block, and the output end of the miniature air pump communicates with the air vent.

[0015] The above technical solution allows for more precise airtightness testing of thermos cups through a sealed mechanism, ensuring the accuracy of the airtightness test.

[0016] Furthermore, a pad is fixedly connected to the middle of the upper surface of the base plate, and the lower surface of the tank is threadedly connected to the upper surface of the pad. The tank is made of PC fully transparent endurance board material.

[0017] The above technical solution allows for better rotation of the appropriate container size according to the thermos cup size, and the simple connection and fixing structure makes it easier to install and disassemble the container.

[0018] Furthermore, a rubber sealing ring is fixedly connected to the upper end of the inner wall of the tank;

[0019] The above technical solution effectively keeps the thermos cup vertical and prevents it from tipping over by using the rubber sealing ring inside the container.

[0020] Furthermore, multiple tri-color lights are fixedly connected to the front outer wall of the support frame;

[0021] The above technical solution provides visual feedback through the three-color lights, enabling operators to understand the equipment's working status and test results in a timely manner.

[0022] Furthermore, the outer walls on both sides of the mounting frame are fixedly connected to the inner walls on both sides of the support frame, and the upper surface of the visual recognition camera is hinged to the lower surface of the mounting frame.

[0023] The above technical solution, by configuring a visual recognition camera, enables real-time monitoring and automated data analysis of the inspection process, improving production efficiency and inspection accuracy. The automated inspection process reduces manual intervention, increases production line efficiency, and reduces human error.

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

[0025] 1. This utility model proposes an airtightness testing device for the production of thermos cups. Through a fixed mechanism, the thermos cup is manually placed on the upper end of the placement pad. When placed, the outer wall of the thermos cup presses against the clamping strip, which then moves the clamping strip against the movable block on the slide rod. The clamping strip is then lightly fixed by the force of the damping spring, preventing the thermos cup from tipping over before proceeding to the next process. Therefore, the fixed mechanism allows the device to adapt to thermos cups of different specifications, effectively reducing the number of parts to be replaced.

[0026] 2. This utility model proposes an airtightness testing device for thermos cup production. Through a set displacement mechanism, an electric slider drives an electric telescopic rod to move inside an electric slide rail. Then, the electric telescopic rod is lowered so that the upper end of the outer wall of the thermos cup is located in the middle of the two clamping rings. Then, the bidirectional hydraulic rod is retracted, so that the clamping rings firmly clamp the thermos cup and send it into the interior of the container for airtightness testing. This effectively reduces manual labor and can adapt to thermos cups of different specifications, effectively realizing automated operation. Attached Figure Description

[0055] Working principle: During use, by twisting the canister 9, the canister 9 is separated from the pad 2. The canister 9 is replaced with one that matches the specifications of the thermos cup, and an appropriate amount of purified water is poured into the canister 9. Then, the operator manually places the thermos cup on the upper end of the placement pad 604. When placed, the outer wall of the thermos cup presses against the clamping strip 605, causing the clamping strip 605 to abut against the movable block 606 and move along the rod of the slide rod 603. Then, the elastic force of the damping spring 602 causes the clamping strip 605 to lightly fix the thermos cup, preventing it from tipping over before proceeding to the next process. Then, the electric slide rail 701 is activated, causing the electric slider 702 to move the electric telescopic rod 703 inside the electric slide rail 701. Then, the electric telescopic rod 703 is lowered, so that the upper end of the outer wall of the thermos cup is located in the middle of the two clamping rings 707. Then, the bidirectional hydraulic rod 704 is retracted, allowing the clamping rings 707 to pass through. The thermos cup is securely clamped by the spring force of the compression spring 708. Then, the electric slider 702 moves, and the electric telescopic rod 703 and the bidirectional hydraulic rod 704 work in sequence to place the thermos cup into the interior of the container 9. Then, the cylinder 802 drives the conical block 804 to descend, so that the outer wall of the conical block 804 fits tightly against the mouth of the thermos cup. Then, the micro air pump 803 is activated to draw in external air and inject it into the interior of the thermos cup through the ventilation channel 805. Then, multiple wide-angle vision recognition cameras 11 in the prior art are used to identify whether there are air bubbles inside the container 9, thereby performing an airtightness test. When an air bubble is detected in a container 9, the tri-color light 5 of the corresponding container 9 is energized to alarm.
