Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of machine tools, in particular to a machine tool cleaning device and a stamping production system. BACKGROUND

[0002] Stamping is one of the important basic processing methods, which uses a punch to quickly form a metal sheet. Currently, continuous stamping of multiple punch devices is a fast production technology for relatively complex metal sheet parts. However, during continuous stamping, stamping oil needs to be frequently supplied to the punch to maintain the stability of continuous work. In addition, when stamping a metal sheet with a thickness exceeding 4 mm, part of the residual chips will adhere to the die, thereby affecting the subsequent processing quality, so the punch and the stamping die must be cleaned regularly. If the stamping die is complex, the cleaning and oiling actions are also very complex, and it is very difficult to implement.

[0003] Currently, the punch is not provided with a position-fixed air blowing device and an oil spraying device, which can realize the cleaning function. However, due to the fixed position of the device, the cleaning range is limited, and the chip adhesion problem cannot be solved. In addition, if the device is to be modified, each punch needs to be modified, which is costly, and a cleaning program needs to be developed for each device, which is time-consuming and laborious, and cannot be standardized. In addition, the air blowing device and the oil spraying device provided on the punch have poor universality and cannot be applied to complex dies. CONTENT OF THE UTILITY MODEL

[0019] In order to make the person skilled in the art better understand the technical solutions of the present disclosure, and fully understand and implement the implementation process of the present disclosure how to apply technical means to solve technical problems and achieve corresponding technical effects, the technical solutions in the embodiments of the present disclosure will be described clearly and completely in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all embodiments. The embodiments of the present disclosure and various features in the embodiments can be combined with each other without conflict, and the technical solutions formed thereby are within the protection scope of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by the person skilled in the art without creative labor shall be within the protection scope of the present disclosure.

[0020] It is to be understood that the terms "first", "second", and the like, used in the description and the claims of the present disclosure as well as the foregoing drawings, are used to distinguish between similar objects and are not necessarily used to describe a particular sequential or chronological order. It is to be understood that the use of the terms so construed can be interchanged, where appropriate, to describe the embodiments of the present disclosure described herein in other than the particular order described. Also, the terms "comprising", "having", "including", and "containing" are to be construed open-ended terms (i.e., meaning "including, but not limited to") unless otherwise noted to exclude such other items. All structural and functional changes that do not depart from the spirit of the present disclosure are intended to be embraced by the appended claims.

[0021] It is to be understood that the steps illustrated in the flow charts of the drawings can be performed in a computer system such as a set of computer executable instructions and, although the steps are illustrated in a particular order, in some cases, the steps can be performed in a different order than illustrated or described herein.

[0022] The embodiment provides a machine tool cleaning device, which can be used for cleaning, oil spraying and other operations of the machine tool, especially the punch press, to supplement the stamping oil of the punch press to improve the stability of continuous work, and clean the stamping die to remove the cutting on the surface and reduce the influence on the subsequent process, thereby improving the surface quality of the product. The machine tool cleaning device can sequentially operate on multiple punch presses, thereby meeting the needs of continuous stamping.

[0023] As shown in Figures 1 to 4 The machine tool cleaning device provided by the embodiment includes a vehicle body 1, a mechanical hand mechanism 2, an oil spraying assembly 3 and a cleaning assembly.

[0024] The vehicle body 1 can walk on the ground or on a track according to a preset track, for example, between punch presses. The vehicle body 1 is provided with a barrier detector 11, an alarm 12 and an emergency stop switch 13. The barrier detector 11 is used to detect obstacles around during walking, for example, to slow down or stop when an obstacle is detected in front of the walking direction. The alarm 12 is used to alert the state during walking or working. The emergency stop switch 13 is used for the operator to press in an emergency, and the vehicle stops immediately after pressing.

[0025] The mechanical hand mechanism 2 is arranged on the top of the vehicle body 1, and has at least three degrees of freedom. The oil spraying assembly 3 is arranged at the end of the arm of the mechanical hand mechanism 2, and is used to spray oil to the target part of the machine tool. The cleaning assembly is arranged at the end of the arm of the mechanical hand mechanism, and is used to clean the target part of the machine tool.

[0026] This embodiment uses a punch press as an example for illustration: During operation, the carriage 1 travels along a preset trajectory. After reaching its destination, it sprays stamping oil onto the punch press via the oil spraying assembly 3 to ensure normal operation. The cleaning assembly cleans the punch press or the molds on it, removing residual chips from their surfaces. The carriage 1 can travel between the punch presses, performing appropriate processing on each press to meet the needs of the stamping process.

[0027] In addition, during operation, the device uses obstacle detectors to detect obstacles and slows down or stops when an obstacle is detected. During startup, shutdown, or operation, alarms can emit audible and visual signals to indicate the device's status. Furthermore, in emergencies, operators can press the emergency stop switch on the vehicle to immediately halt operation, ensuring production safety and personal safety.

[0028] The technical solution provided in this embodiment includes an obstacle detector, an alarm, and an emergency stop switch installed on the vehicle body; the vehicle body can travel on the ground or a track according to a preset trajectory; a robotic arm mechanism is installed on the top of the vehicle body; the robotic arm mechanism has at least three degrees of freedom of movement; an oil spraying component is installed at the end of the robotic arm mechanism's arm for spraying oil onto the target parts of the machine tool; a cleaning component is installed at the end of the robotic arm mechanism's arm for cleaning the target parts of the machine tool, realizing operations such as oil spraying and cleaning of each machine tool, with a large cleaning range, meeting the needs of continuous stamping production, and without requiring modification of all machine tools, thus reducing production costs.

[0029] Based on the above technical solution, the robotic arm mechanism 2 is specifically a six-axis robotic arm, which has high flexibility and work efficiency. A mounting base 21 is provided at the end of the robotic arm mechanism's arm, and the oil spraying assembly 3 and the cleaning assembly are mounted on the mounting base 21.

[0030] Specifically, the mounting base 21 is provided with an oil injection connection interface 31 for installing the spray gun in the oil injection assembly 3. The spray gun is connected to the corresponding oil supply line. There are at least two oil injection connection interfaces 31, which can install at least two spray guns, thereby expanding the stamping oil injection range and improving efficiency. Figure 2 Only the oil spray connection interface 31 on the mounting base 21 is shown; the spray gun is not installed. The spray gun can be implemented using existing technologies in the field. The oil spray connection interface 31 can be set according to the structure of the spray gun and can be used to fix the spray gun by clamping, screwing, snapping, or other methods.

[0031] One embodiment is as follows: the cleaning assembly includes a brush cleaning mechanism 41, which includes a brush cleaning support 411 and a brush disc 412. The brush cleaning support 411 is mounted on the mounting base 21, and the brush disc 412 is mounted on the end of the brush cleaning support 411.

[0032] Furthermore, a brush driver 413 is used to drive the brush cleaning support 411 to translate or swing, thereby adjusting the position of the brush disc 412, expanding the cleaning range, and meeting the needs of chip removal. The brush driver 413 can achieve the above functions through a hydraulic cylinder, pneumatic cylinder, or other means, in conjunction with a linkage mechanism. The robotic arm mechanism 2 drives the brush cleaning mechanism 41 to move, and works with the brush driver 413 to make fine adjustments to its position, which can both expand the cleaning range and improve the cleaning precision, thereby improving the cleaning effect.

[0033] In addition, when cleaning is required, the brush driver 413 drives the brush disc 412 to extend; after cleaning is completed, the brush driver 413 drives the brush disc 412 to retract and stick to the surface of the mounting base 21 to avoid collision with surrounding objects during vehicle movement.

[0034] Another implementation includes a vacuum adsorption mechanism 42, comprising a vacuum adsorption support and a vacuum adsorption head. The vacuum adsorption support is mounted on the mounting base 21, and the vacuum adsorption head is located at the end of the vacuum adsorption support and connected to the vacuum pumping mechanism. The robotic arm mechanism 2 moves the vacuum adsorption mechanism 42 to the target position, causing the vacuum adsorption head to adhere tightly to the surface of the object containing chips. Then, the vacuum pumping mechanism is activated, using negative vacuum pressure to suck away the chips from the object surface, achieving a cleaning effect.

[0035] In this embodiment, the vacuum adsorption mechanism 42 is disposed in the middle of the mounting base 21. There are four oil spraying components; specifically, four oil spraying connection ports 31 are arranged around the vacuum adsorption mechanism 42 for mounting spray guns. The brush cleaning mechanism 41 is disposed on one side of the mounting base 21, and the brush disc 412 extends from one side of the mounting base 21.

[0036] For the vehicle body 1, this embodiment provides an implementation method: the vehicle body 1 includes a vehicle body frame, panels, and a running gear. The vehicle body frame is composed of several longitudinal beams and transverse beams connected together, and the panels surround the top and sides of the vehicle body frame. Specifically, the panel located at the top of the vehicle body frame is the top panel 14, and the panels located on the sides of the vehicle body frame are side panels 15. Specifically, the panel located at the front of the vehicle body frame is the front side panel, the panel located at the rear of the vehicle body frame is the rear side panel, the panel located on the left side of the vehicle body frame is the left side panel, and the panel located on the right side of the vehicle body frame is the right side panel.

[0037] The traveling mechanism is located at the bottom of the vehicle frame, forming a four-point support. The traveling mechanism can be wheels, embedded in the side panels, which can reduce the platform height of the vehicle and improve the stress distribution. Lifting holes or hooks are provided on both sides of the vehicle for easy lifting. The vehicle body strength is designed to be 1.25 times the rated load to ensure that the vehicle body does not deform under certain impacts. The traveling mechanism can be implemented using existing methods in the field that allow it to travel along tracks.

[0038] The aforementioned robotic arm mechanism 2 can be mounted on the top panel 14. Furthermore, for ease of assembly and disassembly, a mounting plate 22 can be installed on the top panel 14, and the mounting plate 22 is fixed to the top panel 14 with bolts. The robotic arm mechanism 2 is fixed to the mounting plate 22 with bolts. The mounting plate 22 can be pre-connected to the robotic arm mechanism 2 as a whole, and then installed as a whole on the top panel 14. During maintenance, only the connection between the mounting plate 22 and the top panel 14 needs to be disassembled.

[0039] The aforementioned obstacle detectors 11 are mounted on the front and rear side panels of the vehicle body. The vehicle body 1 can move forward or backward, and the obstacle detectors 11 mounted on the front and rear side panels detect obstacles during forward and backward movement, respectively. The obstacle detectors 11 can be laser detection devices, and for example, can perform the following functions: 1. Proactive safety protection: Prevents collisions and ensures the safety of personnel and equipment. This is the core function of the obstacle detector 11. When the vehicle travels on the track, a rail-guided vehicle (RGV) solution can be used. The RGV's operating track typically intersects with personnel passageways and other equipment, or needs to navigate through densely packed material rack areas. The obstacle detector 11 monitors the presence of obstacles in real time within a designated "safety protection zone" and triggers a tiered protection mechanism: Level 1 warning (deceleration): When an obstacle enters the "warning zone" (e.g., within 1.5-3m of the RGV), the obstacle detector 11 sends a signal to the RGV control system, and the vehicle automatically decelerates to allow time for subsequent reactions. Level 2 Emergency Stop (Braking): When an obstacle enters the "emergency stop zone" (e.g., within 0.5-1m of the RGV), the obstacle detector 11 immediately outputs an emergency stop signal, the RGV cuts off power and brakes urgently to avoid a collision.

[0040] 2. Path offset correction: Assists navigation and ensures precise operation of the RGV along the track. Some RGVs (such as magnetic track navigation and visual navigation types) rely on preset tracks, but may experience slight path deviations due to ground vibrations, wheel wear, uneven loads, etc. If not corrected in time, this can lead to parking errors or derailment. The obstacle detector 11 can assist in correction in the following two ways: Track edge monitoring: Obstacle detectors 11 are installed on both sides of the RGV, with the laser beam parallel to the track direction, to measure the distance between the RGV and the track edge (or fixed reference objects on both sides, such as shelf columns) in real time; if the distance deviation exceeds the threshold (such as ±5mm), the obstacle detectors 11 feed back a signal to the control system to adjust the wheel steering and correct the running trajectory. Positioning point calibration: Laser reflectors are set at key nodes on the track (such as stops and turns). The obstacle detector 11 calculates the precise distance between the RGV and the positioning point by receiving the "time difference" or "phase difference" of the reflected laser (the error can be as low as ±1mm), calibrates its own position, and ensures docking accuracy (such as when docking with a conveyor belt, the material transfer deviation is ≤2mm).

[0041] The alarm 12 can be installed on the top panel 14 of the vehicle body. The alarm 12 may include an indicator light, which can be a single color or switch between different colors. Alternatively, the alarm 12 can also emit an audio signal to achieve alarm through a combination of sound and light.

[0042] The core value of RGV audible and visual alarms lies in "actively transmitting information and reducing the risks caused by information asymmetry".

[0043] 1. Operational status early warning: Promptly alert personnel to take precautions. Before the RGV performs critical actions such as starting, moving, turning, and parking, an audible and visual alarm can use a "preset signal mode" to warn people in the vicinity of the vehicle that "action is about to take place," preventing people from accidentally entering dangerous areas due to not being aware of the equipment's movement. Start-up / acceleration warning: When the RGV starts from a stationary state or switches from low speed to high speed (e.g., speed ≥ 0.3m / s), it triggers a "slow flashing warning light (e.g., yellow, 1 time / second) + intermittent alarm sound (e.g., "beep-beep-", 2 seconds / time)" to remind nearby personnel that "the equipment is about to move, please do not approach the track"; Turning / Changing Track Warning: In scenarios where multiple tracks intersect or lateral movement is required (such as when an RGV switches from the main track to a branch track), trigger "alternating flashing warning lights (yellow-red switching, 0.5 times / second) + rapid alarm sound (such as 'beep beep beep-', 1 second / 3 times)" to remind equipment or personnel on the intersecting tracks to "pay attention and avoid collisions"; Stop warning: When the RGV approaches the workstation (such as docking with a conveyor belt or shelf), it triggers a "constantly lit warning light (such as green) + a low-volume prompt sound (such as 'beep-' once)" to inform the operator that "the equipment is about to stop and you can prepare for material handover" while avoiding accidental activation by personnel due to sudden stopping.

[0044] 2. Risk Event Warning: The linkage protection system transmits danger signals. When the RGV's active protection (such as laser obstacle avoidance) or passive protection (such as contact buffers) detects a risk, the audible and visual alarms act as "secondary signal amplifiers," amplifying the hazard warning and helping personnel quickly locate the problem. Obstacle warning: When the laser obstacle avoidance sensor detects foreign objects or personnel in the track (such as entering the warning zone), it triggers "fast flashing warning light (red, 0.2 times / second) + continuous alarm sound (such as 'beep-' long sound)", and at the same time, the RGV decelerates, which not only reminds personnel near the obstacle to "evacuate immediately", but also informs staff at a distance that "the track needs to be checked for foreign objects". Collision warning: After a collision occurs and an emergency stop is triggered, the audible and visual alarm will continuously output "strobe warning light (red-blue alternation, 0.1 times / second) + high decibel alarm sound (if above 100dB, continuous long sound)" until the staff manually resets it, to prevent other personnel from accidentally touching the faulty equipment, and at the same time to clearly identify the "accident location" so that maintenance personnel can arrive quickly; Equipment fault warning: When the RGV experiences its own fault (such as motor abnormality, low battery power, track deviation), it will trigger "constant flashing warning light (red, 1 time / second) + intermittent long beep (such as 'beep-beep-', 3 seconds / time)", which is different from the collision warning and indicates "not an external risk, equipment maintenance is required", to avoid personnel misjudging "there is an obstacle" and blindly clearing it.

[0045] The emergency stop switch 13 is located on the top panel 14 of the vehicle body, and the emergency stop switch 13 has the following functions: 1. Immediate containment of sudden dangers: saving personal and equipment safety. When a dangerous situation arises where the automatic protection system is not covered or its response is not timely, the emergency stop switch can be manually triggered to achieve "second-level braking" and prevent the accident from escalating: Personnel safety rescue: If a person is accidentally caught in the RGV (e.g., a limb is close to a moving part), accidentally enters the track and is not detected by the obstacle detector (e.g., a blind spot), or the RGV moves toward the trapped person, nearby personnel can immediately press the emergency stop switch to force the RGV to stop, thus buying time for rescue (the normal emergency stop response time is ≤0.5 seconds, much faster than the delay of the manual call dispatch system). Equipment failure prevention: When the RGV operates abnormally (such as uncontrolled acceleration, wheel derailment, load drop) and the automatic fault protection is not triggered, the operator can press the emergency stop button to cut off the power source and prevent the RGV from colliding with surrounding equipment (such as shelves, robotic arms) or causing secondary damage to itself (such as motor overload burnout). Foreign object risk elimination: If a large foreign object (such as a fallen heavy part) appears on the track and the laser obstacle avoidance fails to identify it due to the limited detection angle, on-site personnel can press the emergency stop in advance to avoid the RGV running over the foreign object, causing track deformation or jamming.

[0046] 2. Proactive intervention for safety assurance: Supporting manual operation scenarios In scenarios requiring manual intervention in RGV operations (such as maintenance and material adjustment), the emergency stop switch is the core locking device to prevent accidental start-up. Equipment repair / maintenance: When maintenance personnel enter the RGV work area (such as to check the drive motor or replace the buffer), they must first press the emergency stop switch of the RGV body and lock it. At this time, even if the dispatching system sends a start command by mistake, the RGV will not be able to run, thus avoiding injury to maintenance personnel from moving parts. Material abnormality handling: If the material being transported by the RGV tilts or scatters (such as pallet displacement), the operator must press the emergency stop button to stop the RGV before sorting the material to prevent it from falling and injuring personnel or equipment. Temporary path adjustment: In multi-track switching scenarios, if the track switching mechanism jams, manual adjustment is required. Pressing the emergency stop button at this time can ensure that the RGV stops stably and avoid collisions caused by sudden movement of the RGV during the adjustment process.

[0047] 3. Final reinforcement of security redundancy: mitigating vulnerabilities in automatic protection. Although the RGV is equipped with automatic protection such as laser obstacle avoidance and buffers, "protection failure" may still occur in extreme cases. The emergency stop switch fills the risk gap through "manual redundancy": In case of automatic system failure: if the obstacle detector lens is completely blocked by oil (no warning), the buffer spring is broken (no braking after collision), or the control system program is disordered (refusing to execute the stop command), the emergency stop switch can directly bypass the control system and forcibly cut off the power circuit (such as motor power supply, hydraulic drive source) to ensure that the RGV stops. In extreme environmental interference scenarios: In scenarios with strong electromagnetic interference (such as welding equipment in workshops) or extreme low temperatures (≤-20℃), the automatic protection system may experience signal interruption or response delay. The emergency stop switch, due to its purely mechanical or low-sensitivity circuit design, can stably trigger braking and is not affected by the environment.

[0048] Furthermore, the bottom of the side panel of the vehicle body 1 is provided with a buffer structure 16 that has elastic deformation capability, such as... Figure 4 As shown, Figure 4 Two buffer structures 16 are provided, or existing technologies in the art can be used. The buffer structure 16 has the following functions: When an obstacle in front of the RGV touches the buffer structure 16, the RGV immediately stops operating. Once the obstacle is removed, the RGV is manually restarted. The core value of the buffer structure 16 lies in its "passive response yet precise protection," and its function can be divided into three main dimensions: 1. Physical buffer: Absorbs collision energy and reduces equipment damage. If a collision occurs during RGV operation (such as an undetected fixed obstacle or other equipment accidentally entering the track), the buffer structure 16 absorbs the impact force through its own structural deformation (such as spring compression or hydraulic damping), preventing the RGV body and load from being directly subjected to force. Protecting critical RGV components: The buffer structure 16 can transform the impact force of a collision from a "rigid impact" (directly transmitted to the frame, wheels, and drive motor) into a "flexible buffer," reducing the risk of frame deformation, wheel derailment, and motor damage; Protecting the load and surrounding equipment: If the RGV is transporting precision parts (such as electronic components and optical components) or heavy materials (such as engine blocks), the buffer structure 16 can reduce load displacement and damage caused by collisions, while avoiding impact damage to equipment such as side racks and conveyor belts.

[0049] Example: When a mobile phone motherboard was being transported by an RGV in a 3C factory, the laser sensor was temporarily blocked by dust and collided with the end block of the track. The buffer structure 16 reduced the impact force from 500N to 80N through the compression of a spring with a stroke of 15mm. The motherboard was not damaged, and the RGV frame only had minor scratches.

[0050] 2. Secondary safety trigger: The linkage control system cuts off power. Each buffer structure 16 integrates a limit switch or pressure sensor. When the buffer structure 16 is impacted and compressed to the set stroke (e.g., 5-20mm), it will simultaneously output an electrical signal to the RGV control system, triggering "dual protection": Emergency braking: The control system immediately cuts off the power to the drive motor to prevent the RGV from continuing forward and causing the collision to escalate; Fault alarm: The workshop dispatch system will issue an audible and visual alarm to prompt staff to investigate the cause of the collision (such as clearing obstacles or repairing sensors) to prevent the accident from happening again.

[0051] 3. Personal protection: Reduce the risk of injury to personnel from collisions. If personnel accidentally enter the RGV operating area and are not detected by active protection systems (such as laser or infrared), the buffer structure 16 can reduce the probability of injury through "flexible contact": The surface of the buffer structure 16 is usually made of soft materials such as polyurethane and rubber to prevent metal from directly colliding with the human body; Its buffer stroke (typically 5-30mm) can prolong the collision contact time and reduce the instantaneous impact force according to the momentum theorem (such as reducing the collision force at a speed of 1m / s from 1200N to below 200N, which is far below the human body's tolerance limit), thereby reducing injuries such as fractures and contusions.

[0052] like Figure 5As shown, the traveling mechanism is located at the bottom of the vehicle frame, allowing it to travel along the track and be powered by the track. Track 51 consists of two light rails installed in a pit, with the top edge of the track flush with the ground. After the track is laid, it is fixed with fasteners 52, and then a second layer of concrete is poured to secure it. Copper busbars are welded to the track during installation to ensure stable voltage when the track is powered. During track installation, the track and related accessories undergo secondary insulation treatment to ensure insulation resistance to ground when the track is powered (two coats of insulating varnish and two coats of asphalt varnish are applied to the track). A power transformer 53 is installed beside the track to convert the input 380V power to 36V for supplying the track. The vehicle's power receiving structure can also adopt existing technical solutions in this field.

[0053] A car body drive mechanism is employed to propel the car body along the track in both directions. This drive mechanism can be implemented using electric motors, hydraulic systems, or other methods, and can operate via automatic wire winding and unwinding. Figure 6 The cable chain shown propels the vehicle.

[0054] The above solution employs a composite robot structure integrating an RGV (Rail-Guided Vehicle) and a 6-axis robot, equipped with a cleaning system and an oiling system. During stamping interruptions, the mold surface is cleaned using brushes on brush plate 412 and negative pressure suction, while lubricating oil is sprayed onto the mold via an oil spraying assembly. The composite cleaning robot has a working range of approximately 15m, an RGV movement accuracy of 10mm, and a robotic arm load of approximately 10kg.

[0055] Compared with traditional solutions, the cleaning device provided in this embodiment can perform complex actions using a robotic arm mechanism, which greatly improves the cleaning effect; moreover, one cleaning device can meet the cleaning needs of multiple machine tools, has a high utilization rate, can improve efficiency, and has a low cost.

[0056] Based on the above technical solutions, this embodiment also provides a stamping production system, including: a plurality of punch presses, a track arranged between the punch presses, and a machine tool cleaning device provided in any of the above-mentioned components, the machine tool cleaning device traveling along the track. The machine tool cleaning device provided in this embodiment can travel along the track and perform cleaning operations such as oil spraying and sweeping on the target machine tool, and has the same technical effect as the cleaning device described above.

[0057] In the embodiments provided in this disclosure, it should be understood that the disclosed apparatus and methods can also be implemented in other ways. The apparatus embodiments described above are merely illustrative; for example, the flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of apparatus, methods, and computer program products according to various embodiments of this disclosure.
