Description

Technical Field

[0001] This utility model belongs to the field of workpiece polishing technology, and in particular relates to an automatic deburring and polishing device for magnesium ingots. Background Technology

[0002] After magnesium ingots are produced and formed, burrs, flash, and other processing defects are easily left on the surface. These defects will affect the processing and assembly accuracy of magnesium ingots in subsequent processes. In order to meet the requirements of product identification and quality control, magnesium ingots need to be polished.

[0003] Currently, traditional manual polishing methods are not only inefficient and labor-intensive, but also pose safety and environmental risks due to the flammability and explosiveness of magnesium shavings and the potential for dust dispersion caused by manual operation. Furthermore, manual polishing results in uneven precision, making it difficult to ensure consistent surface quality of magnesium ingots. Therefore, automated mechanical polishing is now the primary method used. For example, an automated silver ingot polishing system disclosed in patent publication number CN110948365B uses a polishing robot to grab the polishing discs in the polishing module and polish the metal ingots within the module, achieving automated polishing.

[0004] However, when polishing, the polishing robot must polish one magnesium ingot before it can polish the next one, and it can only polish one position at a time, resulting in low overall efficiency and making it unsuitable for polishing large quantities of magnesium ingots. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing an automatic deburring and polishing device for magnesium ingots.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic deburring and polishing device for magnesium ingots, comprising a polishing unit, a control cabinet, a feeding plate conveyor, and a discharging plate conveyor, wherein the polishing unit includes:

[0007] The machine casing is located between the discharge end of the feed plate chain and the feed end of the unfeeding plate chain. The machine casing has a channel inside, the feed end of the channel is connected to the discharge end of the feed plate chain, and the discharge end of the channel is connected to the feed end of the unfeeding plate chain.

[0008] Several polishing mechanisms are installed inside the chassis, and the polishing end of the polishing mechanism is located on the inner side of the channel;

[0009] A feeding cylinder is fixedly installed on one side of the feeding end of the channel, and the movable end of the feeding cylinder pushes the magnesium ingot into the interior of the channel. A detection switch for detecting the position of the magnesium ingot is installed on the side wall of the channel located on one side of the feeding cylinder.

[0010] Several pushing mechanisms are installed on the side wall of the machine housing, and the pushing mechanisms push the magnesium ingots through the corresponding polishing mechanisms.

[0011] Preferably, the polishing mechanism includes at least two polishing wheels connected by a drive. The bottom of the housing is detachably connected to a mounting plate, and the polishing wheels are rotatably connected to the mounting plate. The side wall of the channel is provided with a notch that matches the polishing wheel, and one side of the wheel wall of the polishing wheel extends through the notch to the inside of the channel. The mounting plate is equipped with a speed measuring component for monitoring the rotational speed of the polishing wheel. The industrial control cabinet controls the pusher mechanism to work according to the signal fed back by the speed measuring component.

[0012] Preferably, the pushing mechanism includes a pushing cylinder fixedly inserted into the side wall of the chassis, a pushing plate is installed on the movable end of the pushing cylinder, a position switch for detecting the position of magnesium ingots is installed on the side wall of the channel, and the industrial control cabinet controls the operation of the feeding cylinder and the pushing cylinder according to the electrical signal fed back by the position switch.

[0013] Preferably, the speed measuring component includes a mounting cover fixedly installed at the bottom of the mounting plate. An encoder is fixed inside the mounting cover, and the rotating end of the encoder is connected to the wheel axle of the polishing wheel on the same side. The industrial control cabinet controls the corresponding pusher cylinder to work according to the signal fed back by the encoder.

[0014] Preferably, each of the two polishing wheels has a side plate on its opposite side, and both side plates are fixedly connected to the mounting plate. A balancing cylinder is fixedly inserted into the side wall of each of the two side plates. A counter-push plate is fixedly connected to the movable end of the balancing cylinder. The wheel axle of the polishing wheel rotates through the counter-push plate. The industrial control cabinet controls the corresponding balancing cylinder to work according to the signal fed back by the encoder.

[0015] Preferably, a destacking robot and multiple sets of L-shaped positioning blocks are provided on one side of the feeding end of the feeding plate chain. There are two L-shaped positioning blocks in the same set, which are symmetrical to each other. The destacking robot removes the magnesium ingots at the L-shaped positioning blocks and sends them into the feeding end of the feeding plate chain.

[0016] Preferably, a coding machine is provided on one side of the feeding plate chain, and the coding end of the coding machine corresponds to the upper surface of the conveying end of the feeding plate chain. A proximity switch for detecting the position of magnesium ingots is installed on the side wall of the feeding plate chain. The industrial control cabinet controls the coding machine to code the surface of the magnesium ingots according to the electrical signal fed back by the proximity switch.

[0017] Preferably, a wet dust collector is provided on one side of the chassis, and the suction end of the wet dust collector is fixedly connected to a suction pipe, which is connected to the interior of the chassis. The side wall of the channel is provided with multiple suction holes.

[0018] Preferably, the wall of the suction pipe is fixedly connected to several branch suction pipes, and the branch suction pipes correspond to the positions of each polishing mechanism. Solenoid valves are installed inside the branch suction pipes, and the industrial control cabinet controls the operation of the wet dust collector and the corresponding solenoid valves according to the signal fed back by the encoder.

[0019] Compared with existing technologies, the advantages of an automatic deburring and polishing device for magnesium ingots are:

[0020] 1. Through the coordinated operation of the set chassis, channels, several polishing mechanisms, feeding cylinders, several pushing mechanisms, and the feeding plate chain and unloading plate chain, the magnesium ingots are moved and polished along a fixed path through the channel-type polishing structure. This not only allows for simultaneous polishing of multiple sides of the magnesium ingots, but also enables continuous processing of magnesium ingots. It is suitable for large-scale magnesium ingot polishing and has high work efficiency.

[0021] 2. The speed measuring component inside the polishing mechanism can monitor the rotational speed of the polishing wheel. Based on the speed monitoring results, the control cabinet automatically adjusts the operation of the pusher cylinder of the pusher mechanism, thereby dynamically matching the polishing wheel speed with the workpiece pushing rhythm. When the speed measuring component detects that the polishing wheel speed decreases due to increased load, the control cabinet automatically reduces the pushing speed of the pusher cylinder to avoid excessive compression between the workpiece and the polishing wheel, which would cause a sudden increase in resistance and a surge in magnesium chips. When the speed returns to the normal range, the cylinder action rate is increased synchronously to ensure that while guaranteeing polishing accuracy and reducing the risk of magnesium chip explosion, stable production efficiency is maintained, achieving automated closed-loop control of the polishing process.

[0022] 3. Through the cooperation of the set balance cylinder, side plate and reverse thrust plate, the polishing wheel can be automatically applied with reverse thrust based on the rotation speed detected by the speed measuring component. This can avoid excessive wear of the bearing at the polishing wheel shaft caused by the unidirectional pressure between the magnesium ingot and the polishing wheel.

[0023] 4. Through the coordinated operation of the depalletizing robot, L-shaped positioning blocks, inkjet printer, proximity switch, wet scrubber, and suction pipe, the entire process of depalletizing, polishing, and inkjet printing can be automated, further improving work efficiency. The wet scrubber can collect magnesium shavings generated during polishing in real time. At the same time, with the set suction pipe and solenoid valve, the suction force at various locations inside the machine can be automatically adjusted based on the speed detected by the speed measuring component, so that the negative pressure suction of the wet scrubber can be reasonably distributed, improving the collection efficiency of magnesium shavings.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] like Figures 1-7 As shown, an automatic deburring and polishing device for magnesium ingots includes a polishing unit 1, an industrial control cabinet 2, a feeding plate chain 3, and a discharging plate chain 4. The polishing unit 1 includes a chassis 5, which is located between the discharge end of the feeding plate chain 3 and the feed end of the discharging plate chain 4. The chassis 5 has a channel 6 inside, with the feed end of the channel 6 connected to the discharge end of the feeding plate chain 3 and the discharge end of the channel 6 connected to the feed end of the discharging plate chain 4.

[0034] Several polishing mechanisms 7 are installed inside the housing 5, and the polishing end of the polishing mechanism 7 is located inside the channel 6. The polishing mechanism 7 includes at least two polishing wheels 71 connected by transmission. The bottom of the housing 5 is detachably connected to a mounting plate 72, and the polishing wheel 71 is rotatably connected to the mounting plate 72. The side wall of the channel 6 is provided with a notch that matches the polishing wheel 71, and the wheel wall on one side of the polishing wheel 71 extends through the notch to the inside of the channel 6. The mounting plate 72 is equipped with a speed measuring component 10 for monitoring the rotation speed of the polishing wheel 71. The industrial control cabinet 2 controls the pusher mechanism 9 to work according to the signal fed back by the speed measuring component 10.

[0035] The feeding cylinder 8 is fixedly installed on one side of the feeding end of the channel 6, and the movable end of the feeding cylinder 8 pushes the magnesium ingot into the interior of the channel 6. A detection switch for detecting the position of the magnesium ingot is installed on the side wall of the channel 6 on the side of the feeding cylinder 8. The detection switch is a photoelectric switch. Several pushing mechanisms 9 are installed on the side wall of the machine box 5, and the pushing mechanism 9 pushes the magnesium ingot through the corresponding polishing mechanism 7. The pushing mechanism 9 includes a pushing cylinder 91 fixedly inserted into the side wall of the machine box 5. A pushing plate 92 is installed on the movable end of the pushing cylinder 91. A position switch 93 for detecting the position of the magnesium ingot is installed on the side wall of the channel 6. The industrial control cabinet 2 controls the operation of the feeding cylinder 8 and the pushing cylinder 91 according to the electrical signal fed back by the position switch 93. The position switch 93 is a photoelectric switch or a pressure switch.

[0036] The speed measuring component 10 includes a mounting cover 101 fixedly installed at the bottom of the mounting plate 72. An encoder 102 is fixed inside the mounting cover 101, and the rotating end of the encoder 102 is connected to the wheel axle of the polishing wheel 71 on the same side. The industrial control cabinet 2 controls the corresponding push cylinder 91 to work according to the signal fed back by the encoder 102. When the rotating end of the encoder 102 rotates synchronously with the wheel axle of the polishing wheel 71, its internal code disk will rotate synchronously. The light-transmitting patterns on the code disk alternately pass through the light source, causing the receiver to output pulse signals. By calculating the interval time between two pulse signals, the rotation speed of the polishing wheel 71 can be determined.

[0037] Each of the two polishing wheels 71 has a side plate 11 on its opposite side, and both side plates 11 are fixedly connected to the mounting plate 72. A balance cylinder 12 is fixedly inserted into the side wall of each of the two side plates 11. A counter-push plate 13 is fixedly connected to the movable end of the balance cylinder 12. The wheel axle of the polishing wheel 71 rotates through the counter-push plate 13. The industrial control cabinet 2 controls the corresponding balance cylinder 12 to work according to the signal fed back by the encoder 102, which can balance the unidirectional extrusion force generated by the magnesium ingot on the polishing wheel 71 to a certain extent.

[0038] A destacking robot 14 and multiple sets of L-shaped positioning blocks 15 are installed on one side of the feeding end of the feeding plate chain 3. There are two L-shaped positioning blocks 15 in the same set, which are symmetrical to each other. The L-shaped positioning blocks 15 can be adjusted and set on a machine base. The position of the L-shaped positioning blocks 15 can be adjusted according to different specifications of magnesium ingots to ensure accurate positioning and a wide range of adaptability. The destacking robot 14 removes the magnesium ingots at the L-shaped positioning blocks 15 and sends them into the feeding end of the feeding plate chain 3, which can realize destacking and polishing in one step.

[0039] A coding machine 16 is installed on one side of the feeding plate chain 4. The coding end of the coding machine 16 corresponds to the upper surface of the conveying end of the feeding plate chain 4. A proximity switch 21 for detecting the position of magnesium ingots is installed on the side wall of the feeding plate chain 4. The industrial control cabinet 2 controls the coding machine 16 to spray code onto the surface of the magnesium ingot according to the electrical signal fed back by the proximity switch 21, which can realize automatic coding of polished magnesium ingots. The proximity switch 21 is a photoelectric switch.

[0040] A wet scrubber 17 is installed on one side of the casing 5. The suction end of the wet scrubber 17 is fixedly connected to a suction pipe 18, and the suction pipe 18 is connected to the interior of the casing 5. Multiple suction holes are provided on the side wall of the channel 6. The wet scrubber 17 includes components such as a venturi tube, a variable frequency fan, a centrifugal separator, pipelines, an outer frame, and a water tank. The wet scrubber 17 generates negative pressure suction. The airflow is rapidly accelerated at the throat of the venturi tube, and the liquid vaporizes. The relative movement of the airflow and the liquid makes them fully mixed. Dust or pollutants and droplets accumulate. In the centrifugal separator, sludge droplets are separated from the airflow. The purified air is discharged from the central pipe to the fan located on the clean air side. Due to the attraction, the pollutant particles scattered in the airflow come into contact with the surface of the washing droplets. The droplets continuously capture pollutant particles to form sludge droplets, which fall into the circulating water tank below.

[0041] The suction pipe 18 has several branch suction pipes 19 fixedly connected to its wall, and the branch suction pipes 19 correspond to the positions of each polishing mechanism 7. The internal parts of the branch suction pipes 19 are equipped with solenoid valves 20. The industrial control cabinet 2 controls the operation of the wet dust collector 17 and the corresponding solenoid valves 20 according to the signal fed back by the encoder 102. The negative pressure suction can be reasonably adjusted based on the rotation speed of the polishing wheel 71 fed back by the encoder 102.

[0042] The operating principle of this utility model is explained as follows: A forklift transports the magnesium ingot stack to the L-shaped positioning block 15, which positions the stack. The stack is then lowered, and the control cabinet 2 is activated. The control cabinet 2 controls the destacking robot 14 to operate. The destacking robot 14 picks up the magnesium ingots according to a preset program and places them at the feed end of the feeding plate chain 3. The control cabinet 2 controls the feeding plate chain 3 to transport the magnesium ingots to the feed inlet of the channel 6. At this time, the detection switch on one side of the feeding cylinder 8 detects that the magnesium ingot has reached the designated position, and then the detection switch sends a feedback signal to the control cabinet 2. When the ingot is activated, the industrial control cabinet 2 will immediately control the feeding cylinder 8 to operate. The feeding cylinder 8 pushes the magnesium ingot along the channel 6 towards the position of the first pushing cylinder 91. When the magnesium ingot moves to the position of the first pushing cylinder 91, the position switch 93 will detect that the magnesium ingot has reached the designated position. Subsequently, the position switch 93 will send an electrical signal back to the industrial control cabinet 2. The industrial control cabinet 2 will then immediately control the corresponding pushing cylinder 91 to operate. The pushing cylinder 91 pushes the magnesium ingot towards the position of the polishing wheel 71 on the same side through the pushing plate 92, so that the magnesium ingot passes between the two polishing wheels 71. After the industrial control cabinet 2 is started, it will also synchronously control the drive mechanism of the polishing wheel 71. The drive structure (including components such as a motor, belt, and gears) can drive the polishing wheel 71 to rotate in the opposite direction, thereby polishing and grinding the sidewalls of the magnesium ingots and removing burrs. As the first pusher cylinder 91 pushes, the magnesium ingot moves to the position of the next pusher cylinder 91. The position switch 93 feeds back an electrical signal to the industrial control cabinet 2 based on the position of the magnesium ingot. The industrial control cabinet 2 then controls the first pusher cylinder 91 to return and controls the feeding cylinder 8 to continue pushing the next magnesium ingot into the channel 6. At the same time, the industrial control cabinet 2 controls the pusher cylinder 91 at the current position of the magnesium ingot that has been polished for the first time to... The extension mechanism pushes the magnesium ingot to the next polishing mechanism 7, continuing to polish the sidewall of the magnesium ingot until it moves from the discharge end of the machine 5 to the unloading plate chain 4. At this time, the magnesium ingot moves along the unloading plate chain 4. When it passes the position of the proximity switch 21, the proximity switch 21 will send an electrical signal to the industrial control cabinet 2. At this time, the industrial control cabinet 2 controls the inkjet printer 16 to work. The inkjet printer 16 will then perform inkjet printing on the sidewall of the magnesium ingot it passes through (when the inkjet printer 16 is working, the unloading plate chain 4 is paused to ensure the accuracy of the inkjet printing position). The inkjet-printed magnesium ingot is discharged through the unloading plate chain 4.

[0043] When the polishing wheel 71 rotates, its axle drives the rotating end of the encoder 102 to rotate synchronously, allowing the encoder 102 to detect the rotational speed of the polishing wheel 71's axle. Because different magnesium ingots have varying degrees of burrs on their sidewalls, the friction between the polishing wheel 71 and the magnesium ingot differs. When the roughness of the magnesium ingot's sidewall is greater, the friction on the polishing wheel 71 increases synchronously. Under the same driving power, the rotational speed of the polishing wheel 71 decreases. If the pushing cylinder 91 continues to push the magnesium ingot at the original pushing speed, it may cause excessive grinding pressure between the magnesium ingot and the polishing wheel 71, damaging both the magnesium ingot and the polishing wheel 71. Therefore, when the speed of the polishing wheel 71 is detected to have decreased, [the encoder 102 detects this]. The industrial control cabinet 2 will control the pushing speed of the corresponding pusher cylinder 91 to slow down. Conversely, when the roughness of the magnesium ingot sidewall is small, there are fewer burrs to be removed by grinding. At this time, the pushing speed of the magnesium ingot pushed by the pusher cylinder 91 will increase, which can improve the polishing efficiency to a certain extent. At the same time, the industrial control cabinet 2 can also count the polishing speed of the polishing wheel 71 on each magnesium ingot. If the polishing wheel 71 rotates too fast for N consecutive magnesium ingots (the value "N" can be preset by the industrial control cabinet 2 according to the polishing wheel 71 and the specific composition of the magnesium ingot), the industrial control cabinet 2 will issue an early warning to remind the personnel to check the wear of the polishing wheel 71 to avoid excessive wear of the polishing wheel 71 affecting the polishing effect of the magnesium ingot.

[0044] Meanwhile, as the rotation speed of polishing wheel 71 slows down, it indicates that the magnesium ingot is exerting a large reverse force on polishing wheel 71. At this time, the industrial control cabinet 2 controls the corresponding balancing cylinder 12 to work. The balancing cylinder 12 pushes the reverse thrust plate 13 to move closer to polishing wheel 71, thereby applying a reverse balancing thrust to the wheel shaft of polishing wheel 71. Since the magnesium ingot will exert opposite squeezing forces on the two polishing wheels 71 when it passes between them, the balancing cylinder 12 can apply a thrust to the wheel shaft of polishing wheel 71 to balance the squeezing force to a certain extent, avoiding excessive wear of the wheel shaft bearing of polishing wheel 71 caused by unidirectional squeezing force, and helping to maintain the continuous and stable rotation of polishing wheel 71.

[0045] After the industrial control cabinet 2 is started, it also controls the wet dust collector 17 to work. The fan inside the wet dust collector 17 generates negative pressure suction at the ends of each suction pipe 19 through the suction pipe 18, and collects the magnesium shavings generated during polishing through the suction holes on the side wall of the channel 6, thus preventing the magnesium dust generated during polishing from escaping. Secondly, when the speed of the polishing wheel 71 is too slow, it indicates that the roughness of the magnesium ingot side wall is large. At this time, the magnesium dust generated during polishing is large. In this case, the industrial control cabinet 2 will control the valve plate of the solenoid valve 20 at the corresponding position to open more, while controlling the valve plate of the solenoid valve 20 at other positions to close less. This increases the negative pressure suction at the position where the solenoid valve 20 is more open, thus increasing the suction force. The system can generate a strong negative pressure suction at locations with high magnesium dust levels, directly removing the newly generated magnesium dust and reducing its escape. Under the same power, this reduces the possibility of magnesium dust escaping. If the polishing wheels 71 at two or more locations have a slow rotation speed, the industrial control cabinet 2 will increase the fan power of the wet dust collector 17 step by step according to the number of slow-rotating polishing wheels 71 to meet the dust collection requirements. When the polishing wheels 71 all rotate at high speeds, the industrial control cabinet 2 will reduce the fan power of the wet dust collector 17 to save energy and reduce consumption. (The specific power adjustment in the step-by-step control of the fan power of the wet dust collector 17 is preset through the industrial control cabinet 2 based on parameters such as the selected variable frequency fan.)

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
