Description

Technical Field

[0001] This invention belongs to the technical field of household appliance manufacturing equipment, specifically relating to an intelligent production line for the production of electric stoves and gas stoves. Background Technology

[0002] Existing electric and gas stove production lines generally use a free-flow conveying method, where the material movement speed on the production line is uncontrolled, and the production cycle cannot be adjusted according to actual capacity requirements, making it difficult to improve production efficiency.

[0003] In the product aging test stage, existing production lines usually rely on manual inspection and judgment of electric stove products one by one. Operators need to manually read the test data and compare it with the standard value, which is not only inefficient, but also prone to human error and missed detection, affecting the stability of product quality.

[0004] In addition, the semi-automatic screw machines, auxiliary tools and fixtures in the existing production lines are usually set up in a decentralized manner outside the line, which occupies a lot of production space, and the equipment layout is messy, which is not conducive to the unified management of the production site.

[0005] In terms of the air supply system, the air pipe joints of the existing production line are mostly arranged in series or with a shared air source. The air pressure between each workstation affects each other. When a joint fails or needs maintenance, production often needs to be stopped for repair, and it is difficult to ensure the air pressure balance of the entire production line.

[0006] In terms of water usage, the cooling water required during aging tests is usually for single use, resulting in serious waste of water resources, and excessively high circulating water temperatures can easily lead to equipment malfunctions. Summary of the Invention

Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the invention.

[0035] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0036] Example 1: Combining Figures 1 to 6 The following technical solution is illustrated in this embodiment: it includes a conveying system 1, an aging test system 3, a dual-end air intake constant pressure supply system 5, a closed-loop water circulation system 6, and an auxiliary equipment integration system 7. The conveying system 1 is equipped with a dual-mode cycle control device 2, which is used to adjust the material conveying speed. The aging test system 3 is used for automatic determination of aging tests.

[0037] The dual-mode cycle control device 2 described in this embodiment includes a free cycle control module and a forced cycle control module, which are switched by a free / forced cycle conversion switch 21.

The forced cycle control module includes a programmable logic controller 22, a forced cycle control path solenoid valve 24, a stopper 25, an air source 26, a magnetic tooling plate 27, and a signal line 28.

The programmable logic controller 22 outputs control signals according to the preset cycle program. After receiving the signal, the forced cycle control solenoid valve 24 drives the stopper 25 to perform blocking or releasing actions, thereby realizing the forced control of the production cycle.

[0038] In this embodiment, the aging test system 3 includes an aging rack 31 and an automatic judgment device. The automatic judgment device includes a current transformer 32, a data processing unit 33, an upper / lower limit setting module 34, a peak detection module 35, and a comparison judgment module 36. The current transformer 32 is installed on the aging rack 31 and is used to collect the working current data of the electric stove product 38 in real time during the aging process. The data processing unit 33 reads the current data collected by the current transformer 32 and compares it with the upper / lower limit setting module 34 and the peak detection module 35 preset upper limit, lower limit, or peak value. When the detected value exceeds the preset range, the comparison judgment module 36 automatically judges the product as unqualified, thereby realizing the automatic judgment function of aging test and realizing qualified / unqualified output 37.

The main frame 47 of the production line is equipped with an auxiliary connecting line 46 to realize the electrical connection with the main control system, so that the equipment layout is more organized and easier to manage.

[0040] The dual-inlet constant pressure gas supply system 5 described in this embodiment includes a main gas pipe 51, a liquefied petroleum gas (LPG) inlet 52, a natural gas inlet 53, gas pipe branch interfaces 54, an independent control valve 55, a gas distribution room 56, and a gas consumption station 57. The main gas pipe 51 runs longitudinally through the production line. The LPG inlet 52 and the natural gas inlet 53 are respectively located at both ends of the main gas pipe 51, forming a dual-inlet structure to ensure the gas pressure balance of the entire production line. The main gas pipe 51 is provided with several gas pipe branch interfaces 54, and each gas pipe branch interface 54 is equipped with an independent control valve 55 to independently control the opening and closing of the branch interface, so that the gas supply of each station does not interfere with each other, which facilitates subsequent maintenance and repair. The LPG inlet 52 and the natural gas inlet 53 are connected to the gas distribution room 56 to supply gas to the gas consumption station 57.

[0041] The closed-loop water circulation system 6 described in this embodiment includes a water pump 62, a water level and flow detector 63, an insulated water tank 64, a cooler 71, and a circulating return water pipeline 73. The inlet of one water pump 62 is connected to a storage tank, and the outlet of the other water pump 62 is connected to the inlet of the insulated water tank 64 via the circulating return water pipeline 73, for injecting circulating water into the insulated water tank 64. The water level and flow detector 63 is installed at the inlet of the insulated water tank 64 to monitor the water flow status in real time and ensure the insulated water tank... The water tank 64 is always in a state of flowing water to prevent the insulated water tank 64 from dry burning due to lack of water; the cooler 71 is set between the outlet of the insulated water tank 64 and the storage tank. The water flowing out of the insulated water tank 64 is cooled by the cooler 71 and then flows into the storage tank for temporary storage. Then it is pumped back to the insulated water tank 64 by the pump 62, forming a closed-loop circulating water circuit to avoid the circulating water temperature from being too high and to realize the recycling of water resources. Temperature transmitter 65, control valve 66 and filter 67 are installed on the circulating return water pipeline 73 respectively.

[0042] In this embodiment, the inlet of the insulated water tank 64 is connected to the return water pipe 61 of the aging rack water tank to facilitate the return of water from the aging rack water tank. A water replenishment control valve 72 is installed on the return water pipe 61 of the aging rack water tank to control the return water pipe. The outlet of the insulated water tank 64 is connected to another water pump 62 through the water supply pipe 70 of the aging rack water tank. A control valve 66, a filter 67, a precision pressure gauge 68, and a pressure stabilizing water tank 69 are respectively installed on the water supply pipe 70 of the aging rack water tank.

[0043] This embodiment uses dual-mode control of free rhythm and forced rhythm, which can flexibly select the conveying method according to product type and order requirements. The free rhythm mode is suitable for multi-variety small-batch production, while the forced rhythm mode is suitable for large-batch standardized production, which effectively improves the overall capacity and adaptability of the production line.

[0044] This embodiment, by configuring a current transformer and a data processing unit on the aging rack, realizes real-time monitoring and automatic judgment of the product's operating current during the aging test. It can set upper limit, lower limit or detection peak value for multi-dimensional judgment, which significantly improves detection accuracy and efficiency and reduces the rate of human error.

[0045] This embodiment integrates external auxiliary equipment such as semi-automatic screw machines into the production line through a double-layer assembly line structure and a hanging basket device, making the equipment layout more compact and neat, reducing the area occupied in the production site, and facilitating centralized management and daily maintenance of the equipment.

[0046] This embodiment solves the problem of uneven air pressure at each station in the traditional series air circuit by using a dual-inlet main air pipe structure and an independent control valve group. Each air pipe joint is independently controlled and is not affected by other joints. When a station needs maintenance, there is no need to stop the line, which improves production continuity and maintenance convenience.

[0047] This embodiment achieves the recycling of water used in aging tests through a closed-loop water circulation system consisting of a water pump, a water flow detector, a cooler, and a storage tank. The water flow detector can monitor the water inlet status of the water tank in real time, effectively preventing dry burning failure. The cooler can reduce the temperature of the circulating water, extend the service life of the equipment, and significantly reduce water consumption.

[0048] Example 2: The dual-mode beat control method in this example is as follows:

[0049] In actual production, when it is necessary to produce multiple models of electric stove products in small batches, the operator will switch the material gas valve to free rhythm mode and manually adjust the gas valve opening according to the product process requirements to control the material movement speed on the production line, so as to adapt to the assembly time requirements of different products.

[0050] When carrying out large-scale standardized production, the operator adjusts the material air valve switch to the forced cycle mode. The programmable logic controller (PLC) outputs control signals to the solenoid valve according to the preset cycle time program. The solenoid valve drives the stopper to perform a blocking and releasing action once at set intervals, so that the material flows on the production line at a fixed cycle, thereby maximizing the production capacity.

[0051] Example 3: The automatic aging test determination method in this example is as follows:

[0052] When an electric cooker product is placed on an aging rack for an aging test, a current transformer collects the operating current signal of the product in real time, and transmits the collected current data to a data processing unit. The data processing unit compares the received current data with a preset parameter range: when the upper limit-lower limit judgment is adopted, if the current value is between the preset upper limit value and lower limit value, the product is judged to be qualified; if the current value exceeds this range, the product is judged to be unqualified. When the peak value judgment is adopted, the data processing unit records the current peak value during the aging process, and compares it with a preset peak value standard to realize automatic judgment.

[0053] Fourth Embodiment: In this embodiment, the water circulation operation mode is as follows:

[0054] Before the aging test starts, a water pump pumps the cooling water in the storage tank to the water tank of the aging rack, a water flow detector monitors the water flow state at the water inlet of the water tank in real time, and the aging test starts after confirming that the water flow is normal. During the aging process, the temperature of the water in the water tank rises after absorbing heat from the product, the hot water flows into a chiller for cooling treatment, the cooled cold water flows back to the storage tank for temporary storage, and is then pumped back to the water tank by the water pump to form a continuous circulating water path. When the water flow detector detects no water flow at the water inlet, it immediately sends out an alarm signal and stops heating to prevent the water tank from dry burning.

[0055] For those skilled in the art, it is apparent that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments are to be regarded in all respects as illustrative and not restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, so that all variations that come within the meaning and range of equivalency of the claims are intended to be embraced therein.

The narrative manner of the specification is merely for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
