Detailed Description
The lithium battery gasket cleaning station comprises an automatic gasket feeding module, a gasket cleaning and air spraying module, a gasket drying module, an automatic gasket discharging module and an empty cartridge clip cleaning module.
In the present invention, the pads to be cleaned are placed in cartridges, each of which can store, for example, 300 pads.
FIG. 1 shows a partial view of an automated shim feeding module of the present invention. The automatic gasket feeding module can comprise a first linear transmission line, a steering unit, a second linear transmission line, a baffle plate unit and a feeding unit.
In the working process, the cartridge clip is manually placed on the first linear transmission line so as to be transmitted forwards. The first linear transmission line is provided with a cartridge clip positive and negative detection sensor (such as a color sensor) which is used for detecting a color label (such as blue) on the side face of the cartridge clip so as to ensure the consistency of the direction of the cartridge clip. If the cartridge clip is put reversely, the system prompts an alarm. The first linear transmission line is also provided with a weight sensor for sensing the change of the load weight on the first linear transmission line, namely the weight change caused by the placement of the cartridge clip. In the invention, when the weight increment detected by the weight sensor does not accord with the preset value, namely the quantity of the gaskets contained in the cartridge clip currently placed on the first linear transmission line does not accord with the preset value (for example, 300 pieces), the motor in the first linear transmission line stops working or reduces the rotating speed, and an alarm device in the first linear transmission line gives an alarm.
The steering unit is connected with the tail end of the first linear transmission line and the start end of the second linear transmission line and used for enabling the movement direction of the clip output by the first linear transmission line to be changed by 90 degrees so as to enter the second linear transmission line which is perpendicular to the first linear transmission line. In the present invention, for the convenience of manual operation, the movement direction of the clip is parallel to the long sides of the gasket on the first linear transmission line, and correspondingly, the movement direction of the clip becomes parallel to the short sides of the gasket on the second linear transmission line.
The steering unit has an inclined portion and a flat portion (not shown for reasons of simplicity). One end of the inclined part is connected
The first linear transmission line has a tail end and the other end connected to the flat portion, and has a relatively small friction coefficient (relative to the linear transmission line). Therefore, when the clip is brought to the tail end of the first linear transmission line, it will enter the inclined portion of the steering unit based on the inertia effect and accelerate down the inclined portion to the flat portion.
The flat portion has a shape substantially conforming to the cartridge holder and is slightly larger than the cartridge holder, and has a relatively small coefficient of friction. In the present invention, the cartridge holder is rectangular in shape, the flat portion accordingly has a substantially rectangular shape, and one short side connects the inclined portions to receive the cartridge holder. A first air pad portion (not shown) is provided at the other short side of the rectangular flat portion. One long side of the rectangular flat portion is connected to the start end of the second linear transmission line, and a second pad portion (not shown) is disposed at the other long side.
The first air cushion portion has a shape similar to a short side section of the cartridge clip, and the second air cushion portion has a shape similar to a long side section of the cartridge clip. The first air cushion portion may include a plurality of first air cells secured to the first base plate, wherein the first air cells constitute an inwardly facing surface of the first air cushion portion. The second cushion portion may include a plurality of second air cells secured to the second base plate, wherein the second air cells form an inwardly facing surface of the second cushion portion. Each first air cell is in gaseous communication with a respective second air cell, and preferably the air passage between each first air cell and the respective second air cell is provided of the same size and length.
According to the invention, when the clip is accelerated into the flat part through the inclined part, the clip can be collided with the first air cushion part immediately, and the movement along the first linear transmission line direction is stopped under the action of the first air cushion part. Meanwhile, under the impact action between the cartridge clip and the first air cushion part, the incompressible air in the first air bag is discharged out of the first air bag under the extrusion of the impact force and enters the second air bag along the air passage, so that the second air bag is inflated. Since the air passages between the first air cells and the second air cells have the same length, the plurality of second air cells in the second air cushion portion are inflated at substantially the same time and bulge inward, thereby generating an inward force on the flat portion by means of the clip of the second air cushion portion to push the clip toward the beginning of the second linear transmission line. As will be appreciated by those skilled in the art based on the foregoing description, the angle of inclination of the inclined portion and the smooth surfaces of the inclined and flat portions will facilitate 90 degree turning of the direction of movement of the stack of trays by means of the movement energy provided by the first linear transport line to the clip. By means of the steering unit of the invention, the 90-degree steering of the moving cartridge clip can be realized with a very simple and durable structure and without additional energy consumption, thereby avoiding the complex structure in the existing mechanical steering mechanism and the possible mechanical damage to the cartridge clip.
The second linear transport line moves the clip in the direction of the short side of the clip and enters the stop unit (not fully shown) at its trailing end. The baffle plate unit is provided with a bottom plate which is approximately rectangular, one long edge of the rectangular bottom plate is connected with the tail end of the second linear transmission line, and a movable baffle plate is arranged at the other long edge of the rectangular bottom plate. When the cartridge clip enters the baffle plate unit, the movable baffle plate moves to a preset position under the driving of the motor, so that the cartridge clip is positioned for subsequent operation. Those skilled in the art will readily appreciate that the predetermined position of the flapper can be set according to the size of the cartridge clip and will not be discussed in detail herein.
In the present invention, the inclined portion is preferably disposed at an angle of 4 to 7 degrees with respect to the bearing surface of the first linear transmission line in consideration of stability and impact force, and further preferably, smooth stoppers may be disposed at both sides of the inclined portion to restrict the movement of the cartridge.
The loading unit comprises a cartridge transferring assembly and a gasket loading assembly, for example, as shown in fig. 2-3. The cartridge clip transfer assembly includes a holding portion and a transfer portion. The clamping portion may comprise a jaw for clamping the cartridge; the shifting part is used for driving the clamping part to move so as to enable the cartridge clip to reach the feeding station.
The gasket feeding assembly comprises a gasket lifting part, a feeding tray sucking part and an empty cartridge clip material returning part. The gasket jacking part comprises a lifting cylinder and a height sensor. When the cartridge clip moves the loading assembly to move the cartridge clip with the gasket to the loading station, the lifting cylinder jacks up the gasket from the cartridge clip, and the gasket is lifted to the preset height under the cooperation of the height sensor.
The feeding sucker part comprises a turntable mechanism and a sucker mechanism. As shown in fig. 3, the turntable mechanism includes a turntable, a gear, a rack, a cylinder, and a buffer. In the work, the cylinder drives the rack and makes rectilinear motion, and the gear drives carousel rotary motion through the meshing with the rack, and the buffer is used for buffering spacing after the carousel rotates to the predetermined position, avoids taking place impact vibration.
In the invention, the turntable is provided with a sucker mechanism every 90 degrees. As shown in fig. 3, when the turntable rotates to the feeding station, the pad at the preset height position (i.e. the uppermost pad) will be attracted to the suction cup mechanism, and when the suction cup mechanism further rotates to the feeding station, the suction cup mechanism releases the attraction to the pad.
The sucking disc mechanism comprises a plurality of sucking discs made of elastic materials, a vacuum cavity, an electromagnetic valve, an air inlet channel, an air exhaust channel, an air source and an auxiliary adsorption piece. As shown in fig. 4, a plurality of suction cups are distributed on the outer surface of the suction cup mechanism, which is in gas connection with the vacuum chamber. The vacuum cavity is respectively connected with an air inlet channel and an air outlet channel through a two-position three-way electromagnetic valve, wherein the air inlet channel is connected with a high-pressure air source, and the air outlet channel is connected with an air extracting pump through a one-way valve. The auxiliary adsorption piece can comprise a micro motor, an eccentric wheel and a transmission rod, one end of the transmission rod is connected with the eccentric wheel, and the other end of the transmission rod is connected with the sucker.
In the working process, when the sucker mechanism rotates to the position above the gasket (namely a feeding station), the control unit controls the electromagnetic valve to enable the vacuum cavity to be communicated with the exhaust channel, negative pressure is formed in the vacuum cavity and near the sucker through air suction operation, and the gasket below the sucker is adsorbed on the sucker under the action of the negative pressure. Because the adsorption phenomenon may exist between the gaskets which are stacked and stored, in the invention, in order to adsorb only a single gasket at a time, when the sucking disc adsorbs the gasket, the micro motor starts to drive the eccentric wheel to rotate, the eccentric wheel drives the transmission rod to vibrate up and down slightly, and the adhesion phenomenon between the adjacent gaskets is avoided through the slight vibration, thereby realizing the effect of adsorbing one gasket.
When the turntable rotates further (for example, rotates 180 degrees) so that the sucker mechanism reaches the discharging station, the control unit controls the electromagnetic valve to enable the vacuum cavity to be communicated with the air inlet channel, and therefore high-pressure air in the high-pressure air source enters the vacuum cavity through the air inlet channel and is sprayed outwards through the sucker. The pad attracted to the surface of the suction cup is thus detached from the suction cup by the jet of air and moves in a predetermined direction. In the present invention, since the air jet not only plays a role of separating the spacer from the suction cup but also plays a role of moving the separated spacer toward the predetermined discharging position, the air jet needs to have a good directional stability, and for this reason, the suction cup of the present invention adopts an inverted cone shape and the size of the opening cannot be excessively large, for example, the opening diameter is preferably between 3 and 4 cm.
When the loading of all the gaskets in one cartridge clip is finished, the lifting cylinder descends and returns to the initial position. And then, the empty cartridge clip returning part clamps the empty cartridge clip into the empty cartridge clip cleaning module to clean the empty cartridge clip.
As shown in fig. 5, the gasket cleaning and air showering module includes a transmission line, a rough cleaning portion, a fine cleaning portion, an air showering portion, and an automatic opening and closing device for the protection cover. As mentioned above, at the emptying station, the mat will be released by the suction cups and placed on the transport line of the mat cleaning and showering module by means of the jet air flow output by the suction cups. In the gasket cleaning and air spraying module, the gasket passes through the rough cleaning part, the fine cleaning part and the air spraying part in sequence under the driving action of the transmission line so as to undergo cleaning operation.
In the invention, the rough washing part comprises rough washing nozzles connected with a high-pressure water source, and the rough washing nozzles are uniformly arranged above and below the transmission line along the transmission line so as to ensure that the upper surface and the lower surface of the gasket are continuously washed in the process of passing through the rough washing part, and most impurity particles on the surface of the gasket are cleaned. The coarse washing spray head preferably adopts a universal spray head so as to conveniently adjust the washing angle. The fine washing part has the same structure and arrangement as the rough washing part, and is different in that the filtered water contained in the connected high-pressure water source has a higher level than the rough washing part, thereby further ensuring the water washing effect on the surface of the gasket.
The air shower part comprises a high-pressure air source, air nozzles and a servo mechanism, wherein a plurality of rows of air nozzles are arranged above and below the air nozzles along the transmission line, the air nozzles blow the upper surface and the lower surface of the gasket simultaneously under the driving of the servo mechanism, and the moisture remained on the surface of the gasket is blown off.
The automatic protective cover opening and closing device comprises a protective cover and a driving air cylinder, and the program control air cylinder drives the protective cover to be automatically opened and closed.
As shown in fig. 6, the tuyere may include a hollow truncated cone-shaped outer shell, a cylindrical inner post, and an air outlet hole. The periphery of the inner column is provided with a plurality of spiral grooves, the spiral grooves are abutted to the inner side wall of the outer shell to form a plurality of spiral air passages, the center of the narrow end face of the outer shell is provided with an axial pore, and the inner side wall of the outer shell is connected with the spiral air passages through a conical cavity on the inner side to form an air outlet. In the invention, the included angle between the spiral groove and the bottom surface of the inner column is 10-15 degrees, the inner taper angle of the inner side cavity is 60-65 degrees, the length of the inner column is 20-26cm, and the diameter of the spiral air passage is 3-6mm, so that a longer flow channel is formed in the tuyere, and the gas has a larger tangential flow velocity, thereby enhancing the speed of the gas output by the tuyere and having a specific flow direction, and compared with the common tuyere, the blowing effect can be effectively improved.
After leaving the gasket cleaning and air showering module, the gasket enters the gasket drying module under the driving of the transmission line. The gasket drying module may include an air heating part and a fan. The air heating part includes an electric heater and a temperature sensor that detects an air temperature to control the electric heater to heat the air to a preset temperature. The fans are arranged above and below the transmission line along the transmission line so as to blow hot air in the air heating part to the front and back surfaces of the gasket to dry the surface of the gasket. The sensor ensures that the fan can be detected when damaged.
In order to avoid secondary pollution of the cartridge clip to the gasket, an empty cartridge clip cleaning module is further arranged in the gasket cleaning station, so that the empty cartridge clip pushed out by the gasket automatic feeding module is cleaned. In the present invention, the empty cartridge cleaning module may include an ultrasonic cleaning assembly and a vacuum drying assembly.
The ultrasonic cleaning assembly comprises a cleaning tank, an ultrasonic generator and an auxiliary cleaning part, wherein the cleaning tank is used for receiving the empty cartridge clip and is filled with cleaning liquid. The ultrasonic generator is used for providing an ultrasonic signal to the cleaning tank and comprises a generator for providing electromagnetic energy and a transducer for converting the electromagnetic energy into mechanical vibration energy. Preferably, a plurality of ultrasonic generators may be provided at the bottom of the cleaning tank.
As shown in fig. 7, the auxiliary washing part may include a water pump (not shown), inner and outer cases, two input nozzles, a center shaft, a driving wheel, a mixing wheel, and first and second passive air inlets. The inner and outer housings are fixed to the center shaft by a seal bearing, and define a first fluid space between the inner and outer housings, and a second fluid space between the inner housing and the center shaft, wherein a first tapered cylindrical portion is formed at a lower portion of the outer housing, and correspondingly a second tapered cylindrical portion is also formed at a lower portion of the inner housing. An outlet of the second fluid space is defined between the tail end of the second conical cylinder part and the gas mixing wheel and is communicated with the first fluid space. An outlet of a first fluid space is defined between the tail end of the first conical cylinder part and the gas mixing wheel and serves as a liquid outlet of the auxiliary cleaning part.
Two input nozzles are provided on the side of the housing and the nozzle outlets are substantially aligned with the vanes of the drive wheel. The first passive air inlet is positioned above the driving wheel and arranged on the upper end surface of the shell. The water pump pumps out the liquid in the cleaning tank and sprays the liquid onto the blades of the driving wheel through the input nozzle, so that the driving wheel, the central shaft and the gas mixing wheel rotate together. The air near the drive wheel is impacted by the liquid at high speed, and simultaneously the liquid and air are thrown by the drive wheel towards the inner wall of the housing, whereby a low pressure zone is formed near the drive wheel, whereby air enters the first fluid space via the first passive inlet and the air is broken up into fine bubbles, premixing with the liquid, under the impact of the liquid and the cutting action of the drive wheel blades.
The liquid mixed with air reaches the vicinity of the air mixing wheel through the space between the first and second tapered cylindrical parts under the action of gravity, the air mixing wheel rotating at high speed throws the liquid of the attachment towards the outlet of the first fluid space, and at the same time, the second fluid space is also formed with a low pressure region, so that air will also enter the second fluid space through the second passive air inlet (which is provided on the side of the inner housing). The air sucked in from the second fluid space is dispersed into fine bubbles under the shearing and dispersing action of the air mixing wheel and is fully mixed with the nearby liquid, so that high-speed liquid rich in bubbles is formed nearby the air mixing wheel, and the liquid is sprayed out from the cleaning auxiliary unit through the outlet of the first fluid space. Those skilled in the art will readily appreciate that, in use, the drive wheel is located above the liquid level of the cleaning tank and the air mixing wheel is located below the liquid level of the cleaning tank.
In the cleaning tank, the empty cartridge clip will be placed near the auxiliary cleaning part, so that the high-pressure (high-speed) water flow output by the auxiliary cleaning part will be able to wash the surface of the cartridge clip to enhance the cleaning capability of the surface thereof; meanwhile, because the high-pressure water flow output by the auxiliary cleaning part is rich in a large number of bubbles, the existence of the bubbles can also enhance the ultrasonic cleaning effect, and the ultrasonic cleaning efficiency is greatly improved. In addition, in the auxiliary cleaning part, the vacuum suction force is generated by the impact of input water flow, so that the energy required by air suction is reduced, and meanwhile, the specific structure can ensure continuous air inlet and ensure the air mixing effect; moreover, as is easily understood by those skilled in the art, due to the existence of the auxiliary cleaning part, the large particles possibly existing in the cleaning tank are crushed by the blades in the auxiliary cleaning part, so that the damage to the surface of the cartridge clip and the damage to the pump caused by the existence of the large particles when the water flow impacts the surface of the cartridge clip can be effectively avoided.
In the empty cartridge clip cleaning module, the empty cartridge clip is transferred to the vacuum drying assembly after being cleaned by ultrasonic waves. The vacuum drying assembly may include a vacuum box, a vacuum unit, and a heating unit. After the empty cartridge clip is placed in the vacuum box, the heating unit heats the inside of the vacuum box (namely, the empty cartridge clip), and meanwhile, the vacuumizing unit vacuumizes the inside of the vacuum box. As will be readily understood by those skilled in the art, in such a vacuum drying module, the drying efficiency can be significantly improved compared to the conventional heating drying method, which is particularly advantageous for the surface drying process of hollow structural members such as empty cartridges. As an example, the heating unit is a resistance wire or any other heating element, and the evacuation unit is realized by means of a vacuum pump.
The automatic gasket blanking module is used for placing the cleaned gasket into the empty cleaned cartridge clip. The automatic gasket blanking module comprises a turntable mechanism and a sucker mechanism. Similar to the automatic gasket feeding module, the turntable mechanism herein may include a turntable, a gear, a rack, a cylinder, and a buffer. When the turntable rotates to the workpiece sucking station, the sucking disc mechanism is operated to suck the gasket away from the transmission line; when the turntable further rotates to the blanking station, the sucking disc mechanism is operated to remove the adsorption of the cushion disc and send the cushion disc into the empty cartridge clip.
The sucking disc mechanism comprises a plurality of sucking discs made of elastic materials, a vacuum cavity, an electromagnetic valve, an air inlet channel, an air exhaust channel, an air source and an auxiliary adsorption piece. The plurality of suction cups are distributed on the outer surface of the suction cup mechanism and are in gas connection with the vacuum cavity. The vacuum cavity is respectively connected with an air inlet channel and an air outlet channel through a two-position three-way electromagnetic valve, wherein the air inlet channel is connected with a high-pressure air source, and the air outlet channel is connected with an air extracting pump through a one-way valve. The auxiliary adsorption piece can comprise a micro motor, an eccentric wheel and a transmission rod, one end of the transmission rod is connected with the eccentric wheel, and the other end of the transmission rod is connected with the sucker.
In the working process, when the sucker mechanism rotates to the position above the gasket, the control unit controls the electromagnetic valve to enable the vacuum cavity to be communicated with the exhaust channel, negative pressure is formed in the vacuum cavity and then near the sucker through air suction operation, and the gasket located below the sucker is adsorbed on the sucker under the action of the negative pressure. When the turntable rotates further (for example, rotates 180 degrees) so that the sucker mechanism reaches the discharging station, the control unit controls the electromagnetic valve to enable the vacuum cavity to be communicated with the air inlet channel, and therefore high-pressure air in the high-pressure air source enters the vacuum cavity through the air inlet channel and is sprayed outwards through the sucker. The pad attracted to the surface of the suction cup is thus detached from the suction cup by the jet of air and moves in a predetermined direction. In the present invention, since the air jet not only plays a role of separating the spacer from the suction cup but also plays a role of moving the separated spacer toward the predetermined discharging position, the air jet needs to have a good directional stability, and for this reason, the suction cup of the present invention adopts an inverted cone shape and the size of the opening cannot be excessively large, for example, the opening diameter is preferably between 3 and 4 cm.
The automatic gasket blanking module further comprises a bar code reading unit which is arranged on the turntable and used for reading the two-dimensional code on the gasket. In the invention, the gasket is provided with the two-dimensional code to record the information such as the gasket cleaning times. When the gasket reaches the scrapping times, the sucking disc mechanism can send the adsorbed gasket into the waste material collecting box on the scrapping station instead of placing the gasket into an empty cartridge clip.
By means of the gasket cleaning station provided by the invention, the gasket can be cleaned in a full-automatic, efficient and energy-saving manner, and the defects in the prior art are overcome.
In the foregoing specification, the principles of the invention have been described with reference to specific exemplary embodiments thereof. It will be apparent to those skilled in the art that various modifications or changes may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
