Description

Technical Field

[0001] The invention relates to the technical field of cold storage ball production, in particular to automatic welding equipment and a method for manufacturing cold storage balls. Background Art

[0002] Cold storage technology is a technology that stores cold energy in advance and releases it when needed to achieve cooling and refrigeration effects. It is widely used in cooling and heat dissipation, refrigeration and temperature control, and other fields, such as cold storage radiators for high-power lasers, cooling systems for large power grids or data centers, and cooling devices for interior buildings, thereby reducing dependence on cooling water or refrigerators, and ensuring cooling effects while saving energy and reducing emissions. Among them, volumetric packaged cold storage equipment has become the development direction of cold storage equipment due to its simple structure, high reliability, and good cooling performance. Among them, the cold storage container containing a large number of densely stacked cold storage balls is the core device of the volumetric packaged cold storage equipment. The quality of the cold storage balls directly affects the cold storage performance of the cold storage device.

[0003] The cold storage ball consists of a hollow spherical shell and a cold storage liquid encapsulated in the spherical shell. The current production of cold storage balls is mainly manual work with a low degree of automation. The main production process is: fixing the hollow spherical shell to the fixture, processing the injection hole, injecting the cold storage liquid, sealing and welding the injection hole, grinding the weld point, and inspecting the quality of the weld point. The production mode based on manual work requires a large number of operators, which is labor-intensive and time-consuming, with low production efficiency, and is difficult to operate, with poor welding quality and a high scrap rate. In addition, the amount of cold storage liquid injected depends on manual experience and cannot be quantified, which easily leads to inconsistent cold storage liquid content. However, a single cold storage device is composed of a large number of cold storage balls densely stacked, and the demand for cold storage balls is relatively large.

[0004] Therefore, it is urgent to propose an automated welding equipment and method for manufacturing cold storage balls to solve the problems of low production efficiency, low yield rate and long working hours. Summary of the invention

[0005] In view of the above facts, in order to solve the problems of low production efficiency, low yield rate and long working hours, the present invention further designs an automatic welding equipment and method for manufacturing cold storage balls.

[0006] To achieve the above object, the present invention adopts the following technical solution:

[0007] Solution 1: An automated welding equipment for manufacturing cold storage balls, including: a frame, a frame table, a positioning clamp, a turntable processing table, and a functional mechanism;

[0008] The frame is equipped with a frame table, a turntable processing table is installed on the frame table, eight functional mechanism installation positions are evenly arranged on the frame table, the eight functional mechanism installation positions include seven functional mechanism installation positions and one spare mechanism installation position, and the positioning clamps are evenly installed on the turntable processing table;

[0009] The functional mechanisms include a feeding mechanism, a punching mechanism, a liquid injection mechanism, a wire inserting mechanism, a welding mechanism, and a grinding mechanism. The feeding mechanism, the punching mechanism, the liquid injection mechanism, the wire inserting mechanism, the welding mechanism, and the grinding mechanism are installed clockwise on seven functional mechanism installation positions.

[0010] Furthermore: the bottom surface of the turntable processing table is connected to the top surface of the reducer, the bottom of the reducer is connected to the servo motor, and a zero-point signal sensor is installed on the side of the reducer.

[0011] Further: the control system includes a control panel, an electric control cabinet and a central control system;

[0012] A control panel is installed on the electric control cabinet, and a central control system is placed in the electric control cabinet. The central control system is used to control the intermittent rotation of the turntable type processing table.

[0013] Solution 2: An automated welding method for manufacturing cold storage balls, the specific steps are:

[0014] Step 1: The loading robot picks up the hollow ball from the vibrating plate and places it in the slot of the positioning clamp currently corresponding to the loading mechanism. The loading step is completed and the turntable processing table rotates 45° clockwise;

[0015] Step 2: The drilling mechanism uses a lifting motor and a high-speed rotating drill bit to drill holes in the hollow ball. After the drilling is completed, the hollow ball with a hole is clamped in the positioning clamp, and the turntable processing table rotates 45° clockwise;

[0016] Step 3: Use the injection mechanism to match the lifting shaft to inject the cold storage liquid into the hollow ball with holes. After the injection is completed, the turntable processing table rotates 45° clockwise;

[0017] Step 4: Insert a small piece of welding wire into the injection hole. After the wire is inserted, the turntable processing table rotates 45° clockwise.

[0018] Step 5: Spot weld the injection hole for inserting the welding wire through the welding mechanism to achieve reliable sealing of the injection hole. After the sealing welding is completed, the turntable processing table rotates 45° clockwise;

[0019] Step 6: Grind the welding point by rotating the grinding tool at high speed to improve the smoothness of the cold storage ball. After grinding, the turntable processing table rotates 45° clockwise;

[0020] Step 7: The unloading mechanism takes out the processed cold storage ball from the slot of the positioning clamp and places it in the recovery storage basket. After unloading, the turntable processing table rotates 45° clockwise, and the current positioning clamp returns to the loading mechanism for the next round of loading and subsequent steps;

[0021] If the positioning clamps on the corresponding workstations of all mechanisms hold small balls that have been processed through all or part of the above steps, the automatic production device for cold storage balls will enter a cycle operation, and the functional mechanisms corresponding to the positioning clamps will operate synchronously within the same time cycle;

[0022] Step 8: After the functional mechanism has finished running, the turntable will rotate 45° clockwise. After it is rotated into place, all functional mechanisms will run synchronously again, and the process will be repeated in this way.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention realizes the automated batch production of the whole process including hollow ball loading, liquid injection hole processing, cold storage liquid injection, injection hole sealing welding, welding point grinding, cold storage ball unloading, etc., thereby improving production efficiency and saving working hours.

[0025] 2. The present invention is fully automatic in control, which effectively improves the product qualification rate and maintains the consistency of product quality. The small balls after liquid injection and welding have no leakage defects, and the quality after liquid injection is maintained within the range of M±0.01g, where M is the initial weight of the small balls. The yield rate is stable at more than 90%, which meets the production needs. BRIEF DESCRIPTION OF THE DRAWINGS
