Description

Technical Field

[0001] This utility model relates to the field of metallurgical casting technology, and in particular to an interference-resistant lifting platform linkage detection mechanism. Background Technology

[0002] In China's non-ferrous metallurgical casting industry, linear chain casting lines are widely used. Water cooling is used midway through the process to transport metal ingots to the final industrial palletizing robot gripping position. Because conventional chain drive mechanisms are employed, the gripping mechanism must have the structural characteristics to vertically lift the metal ingots. Furthermore, the operational conditions of the industrial robot depend on external detection equipment feeding back status signals to mainstream PLC logic controllers such as Siemens for calculation. Therefore, the stable operation of the industrial robot and related equipment depends on the accuracy of the signal feedback from the data acquisition points. Simply put, the data acquisition points need to be as stable as possible and have a certain degree of anti-interference capability for the production line to operate normally. Scientific, stable, and effective signal acquisition is one of the most crucial aspects of automated production lines. However, geographical differences and varying temperatures significantly limit the accuracy of information collected by various sensors. This results in automation devices suitable for southern regions being severely limited in northern regions. Incorrect signal transmission can also lead to unnecessary accidents during production and maintenance, threatening the safety of employees and equipment. In conclusion, it is an inevitable trend to make revolutionary design innovations in the mechanical and electrical aspects of this production process. Utility Model Content

[0003] The purpose of this invention is to provide an interference-resistant lifting platform linkage detection mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An interference-resistant lifting platform linkage detection mechanism, comprising: Linkage support frame, used to fix and support the entire mechanism; The connecting rod assembly is mounted on the connecting rod support frame and achieves mechanical operation through up-and-down movement. The ingot-supporting cylinder is connected to the original base by bolts and is used to vertically lift metal ingot blocks; The slider assembly is connected to the upper end face of the bearing cylinder and cooperates with the connecting rod assembly. The connecting rod lever, driven by the slider pair, is used for displacement. An electromagnetic induction sensor is used to collect the position change signal of the connecting rod lever and feed the signal back to the PLC controller.

[0005] The linkage assembly is a multi-link structure with no sensors inside, and the sensors are located far from the reciprocating mechanical components.

[0006] The slider pair includes a pair of sliders. The movement of the metal ingot block drives the connecting rod to move, thereby triggering a change in the state of the electromagnetic induction sensor.

[0007] The status signal of the electromagnetic induction sensor includes on and off states. After being processed by the PLC controller, a control signal is output to drive the ingot-bearing cylinder to rise or fall.

[0008] The connecting rod support frame is fixed to the crossbeam of the water-cooled conveying mechanism by welding, without the need for additional machining.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This invention employs a multi-link structure, ensuring that no sensors or other components inside the ingot-bearing mechanism are affected by environmental interference during use. With the sensors no longer constrained by the mechanism's position, the potential impact of water vapor icing in northern regions is completely eliminated. Furthermore, the range of sensor selection is no longer limited by structure, space, or environment. Moreover, the sensors themselves are located away from reciprocating mechanical components, minimizing the risk of potential impacts from objects. This effectively improves the accuracy, lifespan, and efficiency of the sensors, while reducing maintenance costs. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, this utility model provides an interference-resistant lifting platform linkage detection mechanism, comprising: a linkage support frame 1 for fixing and supporting the entire mechanism; a linkage assembly 2, mounted on the linkage support frame 1, which realizes mechanical operation through up and down movement; a metal ingot support cylinder 3, which is bolted to the original base and used to vertically lift the metal ingot; a slider assembly 4, connected to the upper end face of the metal ingot support cylinder 3 and cooperating with the linkage assembly 2; a linkage lever 5, driven by the slider assembly 4, for displacement movement; and an electromagnetic induction sensor 6, which collects the position change signal of the linkage lever 5 and feeds the signal back to the PLC controller.

[0023] The connecting rod assembly 2 is a multi-link structure with no internal sensors. Sensor 6 is located away from reciprocating mechanical components, avoiding environmental interference and physical damage, thus reducing maintenance costs and failure rates. The slider pair 4 includes a pair of sliders. The movement of the metal ingot drives the connecting rod lever 5 to shift, thereby triggering a state change in the electromagnetic induction sensor 6. The state signal of the electromagnetic induction sensor 6 includes "on" (1) and "off" (0). After processing by the PLC controller, a control signal is output to drive the ingot-bearing cylinder 3 to rise or fall. The connecting rod support frame 1 is fixed to the crossbeam of the water-cooled conveying mechanism by welding, requiring no additional machining.

[0024] This invention is applicable to automated production lines for metallurgical casting, and can resist interference from low temperature, vibration and moisture, ensuring the stability and reliability of signal acquisition.

[0025] like Figure 5-9 As shown, the mechanism is in the absence of an ingot (any metal ingot). Figure 5 If we describe the (on / off) state of the sensor as (1 / 0), then at this time, electromagnetic induction sensors a, b, and c are in the state of 1, 1, and 0, respectively. The feedback is then sent to the PLC for calculation, and the calculation result is: the ingot cylinder is in the initial state, does not output any signal, and has no action.

[0026] When one ingot is in position, the single slider is pressed down, and the electromagnetic induction sensors a, b, and c change state from 1, 0, 0 to 0, 1, 0. Regardless of the state, the feedback to the PLC for transportation output is always: no action. When two ingots are in position, the mechanism... Figure 6 , Figure 7 When both sliders are pressed down simultaneously, the electromagnetic induction sensors a, b, and c are in the state of 0, 0, 0. At this time, the feedback is sent to the PLC for calculation, and the calculation result is: a rising signal is sent to the ingot-bearing cylinder, and the ingot-bearing cylinder rises.

[0027] When an institution has risen to a certain level, it is in a certain position. Figure 8 In this state, electromagnetic induction sensors a, b, and c are in states 1, 0, and 1, respectively. The feedback is then sent to the PLC for calculation. The calculation result is: the cylinder rises to the position, and a signal to grab the ingot is sent to the palletizing robot. After the grabbing action is completed, the robot sends a grabbing completion signal to the PLC for calculation. The calculation result is: the ingot grabbing is completed, and a cylinder return signal is sent to the solenoid valve. The ingot-bearing cylinder descends, and then the operation cycles through these three main states in sequence.
