Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a PTC cleaning equipment for new energy vehicle production. Background Art

[0002] The PTC heater is an important temperature control component in new energy vehicles. It uses a PTC thermistor as a heating element and has an automatic temperature limit function, so it will not cause safety hazards such as overheating and fire due to excessive temperature. Even in the case of poor heat dissipation conditions, it can self-protect and avoid damage. Therefore, it is commonly used as a heating element in new energy vehicles. After the PTC heater of a new energy vehicle is completed with production welding and processing, it needs to be cleaned to remove residual welding oil, additives, metal processing powder, etc. on the surface. In the prior art, ultrasonic cleaning is often used for cleaning, but the ultrasonic wave has a directionality when propagating in the cleaning liquid, which is prone to generating blind spots, resulting in insufficient cleaning effect. Setting multiple groups of ultrasonic oscillators for cleaning will not only increase costs, but also make it difficult to coordinate and unify the frequencies between different ultrasonic oscillators. As the oscillators age, the frequencies will also deviate. When ultrasonic waves with different frequencies propagate in the cleaning liquid, interference phenomena will occur, reducing the working efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a PTC cleaning equipment for new energy vehicle production to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A PTC cleaning equipment for new energy vehicle production, including an equipment machine table, a cleaning chamber for accommodating a cleaning liquid, and an ultrasonic oscillator for inserting into the cleaning liquid for ultrasonic oscillation. A movement control unit is arranged on the equipment machine table; during the cleaning process of the PTC heater placed in the cleaning chamber, the ultrasonic oscillator is controlled by the movement control unit to insert into the cleaning chamber, contact with the cleaning liquid in the cleaning chamber, and make the ultrasonic oscillator reciprocate to change its position. An elevating orifice plate capable of performing elevating activities is arranged in the cleaning chamber, and the PTC heater placed in the cleaning chamber is controlled to elevate through the elevating activities of the elevating orifice plate.

[0005] A base bushing is provided at the bottom of the cleaning chamber. A sealing optical axis is fixedly arranged at the lower part of the elevating orifice plate, and the sealing optical axis passes through the base bushing in an inserted manner. The elevating orifice plate is driven to elevate by the elevation of the sealing optical axis.

[0006] A main sealing rubber ring is installed in the base bushing, and the base bushing is in sealed contact with the sealing optical axis through the main sealing rubber ring; A detection ring cavity is formed inside the base bushing. The detection ring cavity is arranged around the sealing optical axis. A dynamic rubber ring is arranged below the detection ring cavity. The dynamic rubber ring can expand and contract. When the sealing optical axis is stationary relative to the base bushing, the dynamic rubber ring contracts, so that the dynamic rubber ring is in sealed contact with the sealing optical axis. When the sealing optical axis is moving relative to the base bushing, the dynamic rubber ring expands, so that the dynamic rubber ring is not in contact with the sealing optical axis; A water flow sensor is arranged in the detection ring cavity. When water accumulates in the detection ring cavity, it is detected by the water flow sensor.

[0007] A shrapnel ring groove is formed in the base bushing. Expansion shrapnels are arranged in the shrapnel ring groove. The expansion shrapnels are evenly distributed in a circumferential array. The ends of the expansion shrapnels are inserted into the dynamic rubber ring to apply elastic force to the dynamic rubber ring, so that the dynamic rubber ring has a tendency of elastic expansion.

[0008] The upper part of the dynamic rubber ring is connected with a static sealing corrugated eaves. The other side of the static sealing corrugated eaves is fixedly and sealingly attached to the inner wall surface of the detection ring cavity. The sealing between the detection ring cavity and the dynamic rubber ring is realized through the static sealing corrugated eaves.

[0009] A contraction pressure ring is sleeved outside the dynamic rubber ring. A pressure ring pneumatic control pipe is communicated with the contraction pressure ring. The air pressure in the contraction pressure ring is controlled through the pressure ring pneumatic control pipe, so that the contraction pressure ring expands or contracts. When the contraction pressure ring expands, pressure is applied to the dynamic rubber ring to make the dynamic rubber ring contract.

[0010] A flow equalizing ring bin is formed in the base bushing. An annular air gap is arranged between the upper parts of the sealing optical axis and the flow equalizing ring bin. By jetting air through the annular air gap, the metal slag adhered to the surface of the sealing optical axis can be removed during the process of the sealing optical axis moving downward relative to the base bushing.

[0011] A center pressure plate is fixedly arranged on the lifting orifice plate. The sealing optical axis is fixedly installed with the lifting orifice plate through the center pressure plate. An upper contact rubber ring is embedded on the upper surface of the base bushing. When the center pressure plate moves down to the position, it can be in sealed contact with the upper contact rubber ring, thereby closing the annular air gap.

[0012] A closed pressure eaves, an intermediate cavity section and a pipeline cavity are formed in the base bushing. The closed pressure eaves, the intermediate cavity section and the pipeline cavity are communicated with each other. An extension pipeline is inserted into the pipeline cavity. A closed pressure plate is arranged in the intermediate cavity section. The closed pressure plate is fixedly installed with the extension pipeline.

[0013] The closed pressure plate is penetrated with vent holes. When the closed pressure plate is in extrusion contact with the closed pressure eaves, the closed pressure eaves will block and close the vent holes. A pressure plate spring is arranged on the side of the closed pressure plate away from the closed pressure eaves, so that the closed pressure plate has an elastic tendency to move towards the closed pressure eaves.

[0014] The extension pipe is provided with a side groove on the pipe wall, and an air flow channel is externally connected to the uniform flow ring chamber; an interconnected air supply pipe is arranged below the cleaning chamber, and an opening and closing air valve and a two-position three-way valve are connected to the interconnected air supply pipe, and the interconnected air supply pipe is connected to the air flow channel through the opening and closing air valve.

[0015] The interconnected air supply pipe is connected to the pressure ring air control pipe through the two-position three-way valve, and the two-position three-way valve can control the connection between the pressure ring air control pipe and the interconnected air supply pipe or the connection between the pressure ring air control pipe and the outside atmosphere.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The PTC cleaning equipment of the present invention can perform ultrasonic cleaning on the automotive PTC heater, and the ultrasonic vibrator is controlled by the set mobile control unit to continuously change its position in the cleaning chamber, which can reduce the blind area in the cleaning process and improve the cleaning effect.

[0017] Through the cooperation of structures such as the detection ring cavity, dynamic rubber ring and shrinkage pressure ring set in the present invention, while monitoring the sealing performance between the main sealing rubber ring and the sealing optical axis, during the up and down movement of the sealing optical axis, the dynamic rubber ring can automatically expand, so that the inner side of the dynamic rubber ring is separated from the outer surface of the sealing optical axis, thereby avoiding the wear of the dynamic rubber ring during the up and down movement of the sealing optical axis, making the dynamic rubber ring have a stable sealing effect at the bottom of the detection ring cavity, and improving the stability of the accumulation of liquid in the detection ring cavity when the main sealing rubber ring leaks.

[0018] Through the cooperation of structures such as the central pressure plate, annular air gap, closed pressure plate and extension pipe set in the present invention, after the lifting orifice plate moves down in place, the annular air gap can be closed. At this time, when ultrasonic cleaning the PTC heater, pressure gas is input into the uniform flow ring chamber, and the pressure gas will push open the closed pressure plate, so that the extension pipe extends out and exhausts gas. Bubbles are generated by the gas ejected from the extension pipe, stirring the cleaning liquid in the cleaning chamber to facilitate the dispersion of the sewage; and when the lifting orifice plate jacks up and takes out the PTC heater and the lifting orifice plate moves down and resets, the annular air gap will open. At this time, pressure gas is input into the uniform flow ring chamber, and the gas will be ejected from the annular air gap to the outer surface of the sealing optical axis to remove the metal slag that may adhere to the outer surface of the sealing optical axis, reducing the probability of the metal slag entering between the main sealing rubber ring and the sealing optical axis, and improving the sealing stability of the main sealing rubber ring.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a PTC cleaning device for new energy vehicle production, including an equipment machine platform 1, a cleaning bin 2 for containing cleaning liquid, and an ultrasonic oscillator 4 for inserting into the cleaning liquid for ultrasonic oscillation. A mobile control unit 3 is provided on the equipment machine platform 1, as Figure 1As shown in the figure, the movement control unit 3 includes track drive structures in the X-axis, Y-axis, and Z-axis directions; during the cleaning process of the PTC heater placed in the cleaning bin 2, the ultrasonic oscillator 4 is controlled by the movement control unit 3 to insert into the cleaning bin 2, contact the cleaning liquid in the cleaning bin 2, and cause the ultrasonic oscillator 4 to reciprocate and move to change its position; a lifting orifice plate 5 capable of lifting activities is arranged in the cleaning bin 2, and through holes are formed on the surface of the lifting orifice plate 5 for liquid to flow through. Through the lifting activities of the lifting orifice plate 5, the lifting control of the PTC heater placed in the cleaning bin 2 is carried out.

[0028] A base bushing 6 is provided at the bottom of the cleaning bin 2. A sealed optical axis 7 is fixedly arranged at the lower part of the lifting orifice plate 5. The sealed optical axis 7 passes through the base bushing 6 in an inserted manner, and the lifting of the sealed optical axis 7 drives the lifting orifice plate 5 to lift and move.

[0029] A main seal rubber ring 8 is installed in the base bushing 6. The base bushing 6 is in sealed contact with the sealed optical axis 7 through the main seal rubber ring 8; a detection ring cavity 9 is formed inside the base bushing 6. The detection ring cavity 9 is arranged around the sealed optical axis 7. A dynamic rubber ring 10 is arranged below the detection ring cavity 9. The dynamic rubber ring 10 is made of a softer rubber material, which can ensure the deformation effect. The dynamic rubber ring 10 does not need to be wear-resistant, and the softer rubber material can improve the static seal effect. The dynamic rubber ring 10 can carry out expansion and contraction activities. When the sealed optical axis 7 is in a static state relative to the base bushing 6, the dynamic rubber ring 10 contracts, so that the dynamic rubber ring 10 is in sealed contact with the sealed optical axis 7. When the sealed optical axis 7 is in a moving state relative to the base bushing 6, the dynamic rubber ring 10 expands, so that the dynamic rubber ring 10 is not in contact with the sealed optical axis 7; a water flow sensor 11 is arranged in the detection ring cavity 9. When water accumulates in the detection ring cavity 9, it is detected by the water flow sensor 11.

[0030] A shrapnel ring groove 601 is formed in the base bushing 6. An expansion shrapnel 602 is arranged in the shrapnel ring groove 601. The expansion shrapnel 602 is evenly distributed in a circumferential array. The end of the expansion shrapnel 602 is inserted into the dynamic rubber ring 10 to apply an elastic force to the dynamic rubber ring 10, so that the dynamic rubber ring 10 has a tendency of elastic expansion. A static seal corrugated eaves 603 is connected and arranged at the upper part of the dynamic rubber ring 10. The other side of the static seal corrugated eaves 603 is fixedly and sealingly attached to the inner wall surface of the detection ring cavity 9. The seal between the detection ring cavity 9 and the dynamic rubber ring 10 is realized through the static seal corrugated eaves 603. As Figure 4 shown in the figure, the static seal corrugated eaves 603 is statically sealed through relatively stationary pasting, so that when the dynamic rubber ring 10 expands and contracts, the detection ring cavity 9 and the dynamic rubber ring 10 are always stably closed.

[0031] A shrinkage pressure ring 604 is sleeved outside the dynamic rubber ring 10. A pressure ring pneumatic control pipe 605 is communicated with the shrinkage pressure ring 604. The air pressure in the shrinkage pressure ring 604 is controlled through the pressure ring pneumatic control pipe 605, so that the shrinkage pressure ring 604 expands or contracts. When the shrinkage pressure ring 604 expands, pressure is applied to the dynamic rubber ring 10 to make the dynamic rubber ring 10 contract.

[0032] A flow equalizing ring chamber 606 is formed in the base shaft sleeve 6. An annular air gap 607 is provided between the upper part of the sealed optical shaft 7 and the flow equalizing ring chamber 606. By jetting air through the annular air gap 607, the metal slag adhered to the surface of the sealed optical shaft 7 can be removed during the downward movement of the sealed optical shaft 7 relative to the base shaft sleeve 6, and the gas jetted from the annular air gap 607 can flow axially along the outer surface of the sealed optical shaft 7.

[0033] A central pressure disc 608 is fixedly arranged on the lifting orifice plate 5. The sealed optical shaft 7 is fixedly installed with the lifting orifice plate 5 through the central pressure disc 608. An upper contact rubber ring 609 is embedded on the upper surface of the base shaft sleeve 6. When the central pressure disc 608 moves down to the position, it can be in sealed contact with the upper contact rubber ring 609, so as to close the annular air gap 607.

[0034] A closed pressure eaves 610, an intermediate cavity section 611 and a pipeline cavity 612 are formed in the base shaft sleeve 6. The closed pressure eaves 610, the intermediate cavity section 611 and the pipeline cavity 612 are communicated with each other. An extension pipeline 613 is inserted into the pipeline cavity 612. A closed pressure disc 614 is arranged in the intermediate cavity section 611. The closed pressure disc 614 is fixedly installed with the extension pipeline 613. An air vent hole 615 is formed through the closed pressure disc 614. When the closed pressure disc 614 is in extrusion contact with the closed pressure eaves 610, the closed pressure eaves 610 blocks and closes the air vent hole 615. A pressure disc spring 616 is arranged on the side of the closed pressure disc 614 away from the closed pressure eaves 610. Through the pressure disc spring 616, the closed pressure disc 614 has an elastic tendency to move towards the closed pressure eaves 610.

[0035] A pipe wall side groove 617 is formed on the extension pipeline 613. An air flow channel 618 is communicated with the outside of the flow equalizing ring chamber 606; An interconnected air supply pipe 619 is arranged below the cleaning chamber 2. During operation, the interconnected air supply pipe 619 is communicated with a compressed air pump. An opening and closing air valve 620 and a two-position three-way valve 621 are communicated with the interconnected air supply pipe 619. The interconnected air supply pipe 619 is communicated with the air flow channel 618 through the opening and closing air valve 620.

[0036] The interconnected air supply pipe 619 is communicated with the pressure ring pneumatic control pipe 605 through the two-position three-way valve 621. Through the two-position three-way valve 621, it can be controlled that the pressure ring pneumatic control pipe 605 is communicated with the interconnected air supply pipe 619 or the pressure ring pneumatic control pipe 605 is communicated with the outside atmosphere.

[0037] Such as Figure 5As shown in the figure, a cleaning liquid connecting pipe 201 is connected to the bottom of the cleaning bin 2. The cleaning bin 2 is connected to the cleaning liquid pump in the equipment machine table 1 through the cleaning liquid connecting pipe 201, so as to realize the control of adding and discharging the cleaning liquid in the cleaning bin 2.

[0038] As Figure 5 shown in the figure, a synchronous cross bar 701 is fixedly arranged at the lower end position of the sealed optical axis 7. The multi-group sealed optical axes 7 are uniformly lifted and lowered through the synchronous cross bar 701, and the synchronous cross bar 701 is driven to lift and lower by a lead screw and a motor.

[0039] When the PTC cleaning equipment of the present invention is in use, the PTC heater is clamped and transported into the cleaning bin 2 by a robotic arm. The ultrasonic oscillator 4 is controlled by the movement control unit 3 to insert into the cleaning bin 2, so that the ultrasonic oscillator 4 contacts the cleaning liquid in the cleaning bin 2. While the ultrasonic oscillator 4 generates ultrasonic vibration, the movement control unit 3 controls the ultrasonic oscillator 4 to move back and forth to change the position and reduce the blind area in the cleaning process, thereby improving the cleaning effect.

[0040] After the cleaning is completed, the lifting orifice plate 5 moves upward to eject the PTC heater from the cleaning bin 2, and then it is clamped and transported to the next processing process by a robotic arm.

[0041] As Figure 4 shown in the figure, the lifting and lowering movement of the lifting orifice plate 5 is driven by the sealed optical axis 7. The sealed optical axis 7 and the base bushing 6 are sealed to prevent the cleaning liquid from leaking between the two.

[0042] When the base bushing 6 and the sealed optical axis 7 move relative to each other, the two-way three-way valve 621 controls the pressure ring air control pipe 605 to communicate with the outside atmosphere. At this time, the shrinkage pressure ring 604 deflates, and under the elastic force of the expansion elastic piece 602, the dynamic rubber ring 10 expands, and the dynamic rubber ring 10 does not contact the sealed optical axis 7, so as to avoid the problem of subsequent poor sealing caused by the wear of the dynamic rubber ring 10.

[0043] After the base bushing 6 and the sealed optical axis 7 are relatively stationary, the two-way three-way valve 621 controls the pressure ring air control pipe 605 to communicate with the interconnected air supply pipe 619. The compressed gas in the interconnected air supply pipe 619 enters the shrinkage pressure ring 604 through the pressure ring air control pipe 605, so that the shrinkage pressure ring 604 expands and squeezes the dynamic rubber ring 10, so that the dynamic rubber ring 10 contracts against the elastic force of the expansion elastic piece 602. At this time, the dynamic rubber ring 10 is in sealed contact with the sealed optical axis 7, and as Figure 4 shown in the figure, due to the setting of the static sealing corrugated eaves 603, the lower part of the detection ring cavity 9 is completely closed. In the relatively stationary state of the base bushing 6 and the sealed optical axis 7, once the main sealing rubber ring 8 leaks, the liquid will accumulate in the detection ring cavity 9 until it is detected by the water flow sensor 11.

[0044] When the PTC heater is ultrasonically cleaned, the lifting orifice plate 5 is in the state of being lowered in place. At this time, the central pressure plate 608 is in sealing contact with the upper contact rubber ring 609, so that the annular air gap 607 cannot discharge air upward. At this time, the air opening and closing valve 620 is opened. When compressed gas is input into the uniform flow ring chamber 606 through the air flow channel 618, the gas can only push open the closing pressure plate 614, so that the pressure plate spring 616 is compressed and the extension pipe 613 extends out. The gas is ejected through the vent hole 615 and the pipe wall side groove 617 through the extension pipe 613 to generate bubbles, stirring the cleaning liquid in the cleaning chamber 2 to facilitate the uniform dispersion of the waste liquid. Through the extension activity of the extension pipe 613, the radial dispersion degree of the bubbles is increased.

[0045] After the lifting orifice plate 5 rises to eject the PTC heater and the manipulator clamps and transports away the PTC heater, the lifting orifice plate 5 will descend and reset. During the descent of the lifting orifice plate 5, the sealing optical axis 7 will move downward relative to the base bushing 6. At this time, metal slag may adhere to the surface of the sealing optical axis 7. After being brought into the main sealing rubber ring 8 by the sealing optical axis 7, the sealing performance between the two may be seriously affected.

[0046] At this time, since the annular air gap 607 is in an open state, when compressed gas is input into the uniform flow ring chamber 606, the compressed gas first jets out through the annular air gap 607 to pre-blow the metal slag on the surface of the sealing optical axis 7, reducing the probability of the metal slag being brought between the main sealing rubber ring 8 and the sealing optical axis 7.
