Description

Technical Field

[0001] The utility model belongs to the field of ultrasonic cleaning equipment, in particular to a full-automatic annular ultrasonic cleaning equipment. Background Art

[0002] Ultrasonic cleaning equipment is a machine that uses the ultrasonic principle for cleaning. It generates high-frequency oscillation signals through an ultrasonic generator, which are converted into high-frequency mechanical oscillations through a transducer (vibrator) and propagated into the liquid. Ultrasonic waves radiate forward in the liquid in a sparse and dense manner and generate tens of thousands of tiny bubbles. These bubbles are formed and grow in the negative pressure area during the propagation process, and quickly close in the positive pressure area, forming the so-called "cavitation effect." When the bubbles close, an instantaneous high pressure of thousands of atmospheres can be formed. The continuously generated high pressure is like countless small "explosions", constantly impacting the surface of the object, causing the dirt on the surface of the object and in the gaps to quickly fall off, thereby achieving the purpose of cleaning.

[0003] When cleaning products with frame-shaped structures (such as the frame of a mobile phone), existing ultrasonic cleaning equipment needs to string the frame-shaped products on a specific carrier, but it is difficult for existing ultrasonic cleaning equipment to achieve automated clamping of such products, resulting in low cleaning efficiency; and, in order to process in batches, multiple products are generally stacked and placed in a basket for cleaning, but this will cause cleaning dead corners of the products, affecting the cleaning effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] When cleaning products with frame-shaped structures (such as the frame of a mobile phone), existing ultrasonic cleaning equipment needs to string the frame-shaped products on a specific carrier, but it is difficult for existing ultrasonic cleaning equipment to achieve automated clamping of such products, resulting in low cleaning efficiency; and, in order to process in batches, multiple products are generally stacked and placed in a basket for cleaning, but this will result in dead corners in the cleaning of the products, affecting the cleaning effect.

[0032] In order to solve the above problems, the present embodiment provides a fully automatic annular ultrasonic cleaning device, which can realize automatic clamping of products and has high cleaning efficiency; and can ensure the cleaning effect while cleaning products in batches.

[0033] For the convenience of description, the following product to be cleaned is only an example of a mobile phone middle frame. It should be noted that the fully automatic annular ultrasonic cleaning device of this embodiment can clean various products, especially frame-shaped products that are inconvenient to clamp with some traditional cleaning equipment.

[0034] Reference Figure 1 and Figure 2 , shows a fully automatic annular ultrasonic cleaning device provided by this embodiment, which includes a clamping device, an annular reflux conveying system and a cleaning tank; wherein the clamping device is used to automatically clamp the mobile phone middle frame 200 to be cleaned; the annular reflux conveying system includes a conveying power mechanism 2, an annular track 3 and an annular chain 4, and the conveying power mechanism 2 can drive the annular chain 4 to perform an annular reflux movement; a plurality of clamping devices are slidably installed on the annular track 3 at intervals, and are respectively fixedly connected to the annular chain 4; please refer to Figure 5 and Figure 6 The cleaning tank 1 is used to store cleaning agents and provide an operating space for product cleaning. The cleaning tank 1 is located below the clamping device, and an ultrasonic generating device 11 is provided in the cleaning tank 1.

[0035] When the conveying power mechanism 2 is working, it drives the ring chain 4 to do a ring reflux motion, and the ring chain 4 drives the clamping device to slide along the ring track 3. When the mobile phone middle frame 200 clamped on the clamping device passes through the cleaning tank 1, the ultrasonic generating device 11 in the cleaning tank 1 works to perform ultrasonic cleaning on the product.

[0036] Since the clamping device can realize automatic clamping of the product without manual clamping, the cleaning efficiency is high; and, by adopting a ring-shaped reflux conveying system, the products on multiple clamping devices can be conveyed to the cleaning tank 1 in turn for cleaning. Compared with the prior art of stacking multiple products in a basket for cleaning, this embodiment not only realizes assembly line batch cleaning, but also avoids the existence of cleaning dead corners of the product, thereby ensuring the cleaning effect.

[0037] Specifically, the conveying power mechanism 2 includes a conveying rotary motor 21, a driving sprocket 22 and a driven sprocket 23. The driving sprocket 21 is connected to the rotating shaft of the conveying rotary motor 21. The driving sprocket 22 and the driven sprocket 23 are respectively located at two ends of the annular reflux conveying system, and the annular chain 4 is wound around the driving sprocket 22 and the driven sprocket 23. Among them, the annular chain 4 is located in the inner circle of the annular track 3, and the cleaning tank 1 is located on the outer side of the annular track 3. When the conveying rotary motor 21 is working, the driving sprocket 22 rotates, thereby driving the annular chain 4 to perform an annular reflux motion. Since the clamping device is fixedly connected to the ring chain 4, the conveying power mechanism 2 can drive the clamping device to perform a ring-shaped reflux motion. The ring-shaped reflux conveying system is provided with loading and unloading stations at the front and rear ends. When the clamping device moves to the corresponding station, the clamping device automatically clamps or releases the mobile phone middle frame 200 under the control of the PLC controller or the host computer, so as to provide a loading and unloading robot or a worker for loading or unloading operations.

[0038] Further, refer to Figure 3 and Figure 4 The fully automatic annular ultrasonic cleaning equipment of this embodiment also includes a jig steering mechanism 5, and the clamping device specifically includes a jig 61 for clamping the product, a jig loosening assembly 62 for slidingly installing the jig 61 on the annular track 3, and a jig steering matching assembly.

[0039] Among them, the fixture 61 includes a clamping jaw opening and closing mechanism and at least one group of clamping jaws, a group of clamping jaws has two clamping jaws arranged opposite to each other, and when the clamping jaw opening and closing mechanism is working, it can drive the two clamping jaws in the same group of clamping jaws to move toward each other to clamp or loosen the mobile phone middle frame 200.

[0040] The fixture loosening assembly 62 includes two sets of rollers that are spaced apart and arranged opposite to each other. The two sets of rollers are respectively embedded in grooves on the inner and outer sides of the annular track 3 .

[0041] The jig steering mechanism 5 includes a jig rotating motor 51, a jig rotating motor mounting seat 52 and a steering connection block 53. The jig rotating motor 51 is fixed on the jig rotating motor mounting seat 52, the steering connection block 53 is coaxially connected to the rotating shaft of the jig rotating motor 51, and the end surface of the steering connection block 53 close to the jig 61 is provided with an open groove. The jig steering matching assembly includes a transmission pin 631, a bearing 632 and a bearing seat 633, the bearing 632 is embedded in the bearing seat 633, one end of the transmission pin 631 is used to be embedded in the open groove of the steering connection block 53, and is connected to the steering connection block 53 in a transmission manner, and the other end passes through the bearing 632 and is fixedly connected to the jig 61. When the transmission pin 631 moves along with the endless chain 4 to the position where its horizontal projection overlaps with the horizontal projection of the steering connection block 53, the transmission pin 631 is just located in the open groove. At this time, the endless chain 4 stops moving, and the fixture rotation motor 51 works to drive the steering connection block 53 to rotate. The steering connection block 53 further drives the transmission pin 631 to rotate. Since the transmission pin 631 is fixedly connected to the fixture 61, the fixture 61 and the product thereon can achieve 360° steering under the action of the fixture steering mechanism 5, thereby achieving all-round cleaning without dead angles.

[0042] In some embodiments, in order to monitor the state of the jig 61 in real time so as to perform corresponding operations, the jig steering coordination assembly also includes a jig horizontal sensor 634 and a jig horizontal sensing sheet 635 for detecting whether the plate surface of the jig 61 is parallel to the horizontal plane, and a jig angle sensor 636 and a jig angle sensing sheet 637 for detecting the angle between the plate surface of the jig and the horizontal plane.

[0043] In this embodiment, the jig steering mating assembly includes a plurality of jig angle sensing plates 637, which are fixed on the side of the bearing seat 633 facing the jig 61, and the central angle formed by two adjacent jig angle sensing plates 637 and the rotating shaft of the jig rotating motor 51 is 90 degrees.

[0044] When the jig horizontal sensor piece 635 rotates to a position relative to the jig horizontal sensor 634, the jig horizontal sensor 634 sends a signal to the upper computer to inform the upper computer that the jig 61 is parallel to the horizontal plane. When the jig angle sensor piece 637 rotates to a position relative to the jig angle sensor 636, the jig angle sensor 636 sends a signal to the upper computer to inform the upper computer of the angle at which the jig 61 is currently tilted relative to the horizontal plane.

[0045] Reference Figure 5 , shows the state when the front side (the side with the product clamped) of the fixture 61 is facing upward. In this state, the mobile phone middle frame 200 can be transported normally, and the mobile phone middle frame 200 is located above the cleaning agent. Figure 6, shows the state when the front side of the fixture 61 is facing downward. In this state, the product can be conveyed normally and the product is in the cleaning agent. At this time, the ultrasonic generator 11 in the cleaning tank 1 can be turned on to perform the ultra-clear wave cleaning operation. In this embodiment, the ultrasonic generator 11 is an ultrasonic vibration plate, which is installed in the middle position of the bottom of the cleaning tank 1. In order to achieve a better cleaning effect for the mobile phone middle frame 200, the same ultrasonic generator 11 in the same cleaning tank 1 can generate different ultrasonic frequencies, so that the mobile phone middle frame 200 can be cleaned by multi-frequency ultrasonic cleaning, thereby obtaining a better cleaning effect.

[0046] Reference Figure 7 , shows the process of cleaning the mobile phone middle frame 200 by the fully automatic annular ultrasonic cleaning equipment of this embodiment, and the specific process is as follows:

[0047] When the jig 61 is in the initial state, its front side faces upward, and the mobile phone middle frame 200 is loaded onto the jig 61. The jig 61 automatically clamps the mobile phone middle frame 200, and the conveying power mechanism 2 conveys the jig 61 together with the mobile phone middle frame 200 to the top of the cleaning tank 1. The jig steering mechanism 5 turns the jig 61 together with the mobile phone middle frame 200 180 degrees, and the jig 61 faces downward. The mobile phone middle frame 200 is located below the jig 61 and immersed in the cleaning agent. The ultrasonic generating device 11 in the cleaning tank works to perform ultrasonic cleaning on the product. After the product cleaning result is obtained, the conveying power mechanism 2 turns the jig together with the mobile phone middle frame 200 180 degrees again. At this time, the mobile phone middle frame 200 is located above the jig 61. The conveying power mechanism 2 conveys the jig 61 together with the mobile phone middle frame 200 to the unloading station. A photoelectric sensor can be set at the loading position to realize signal connection with upstream and downstream equipment, thereby realizing the automation of the entire production line.

[0048] In some other embodiments, the fully automatic annular ultrasonic cleaning equipment also includes a high-pressure spray system, which is used to spray a water vapor mixture to rinse the mobile phone middle frame 200. The water vapor mixture explodes after impacting the product, which can better clean the mobile phone middle frame 200. Furthermore, the mobile phone middle frame 200 can achieve 360° steering under the action of the fixture steering mechanism 5, realizing all-round spraying without dead angles, thereby achieving a better spraying effect.

[0049] In some other embodiments, the fully automatic annular ultrasonic cleaning equipment also includes an air drying system, which is used to blow air to the product to air dry the mobile phone middle frame 200 after cleaning. Furthermore, the mobile phone middle frame 200 can achieve 360° steering under the action of the jig steering mechanism 5, realizing all-round air drying without dead ends, thereby achieving better air drying effect.

[0050] In some other embodiments, in order to obtain better cleaning effects, pH meters, conductivity meters, etc. are used to monitor the concentrations of detergents, pure water, etc. in real time. Once the concentration is lower than the set concentration, the system will automatically add detergent to avoid the product being uncleanly cleaned.

[0051] In some other embodiments, in order to obtain better cleaning effect, the temperature of lotion, pure water, etc. is monitored in real time. Once it is lower than the set temperature, the system will automatically start heating. Once it is higher than the set temperature, the system will automatically start cooling to avoid causing the product to be not cleaned thoroughly.

[0052] In some other embodiments, the concentration and temperature of the cleaning agent, the frequency of the ultrasound, the angle and pressure of the spraying, the angle and pressure of the air drying, and the product conveying speed and other parameters can be adjusted according to the target cleanliness of the product.

[0053] In summary, this embodiment develops a special fixture 61 according to the characteristics of the mobile phone middle frame 200, realizes the automatic clamping of the mobile phone middle frame 200, and has high cleaning efficiency. The mobile phone middle frame 200 can be switched at any angle of 360° on the fixture 61, and according to the switching of the angle, all-round and multi-angle online ultrasonic cleaning can be achieved, so that the cleaning effect can be guaranteed while cleaning products in batches.

[0054] In addition, different ultrasonic frequencies can be used according to the specific characteristics of the mobile phone middle frame 200, and the spray pressure and wind pressure can be controlled according to the angle. Thus, the mobile phone middle frame 200 can be comprehensively controlled in terms of moving speed, rotation angle of the fixture 61, ultrasonic frequency, spray pressure, air pressure, etc., and the cleaning effect of the mobile phone middle frame 200 under dynamic movement is optimized, avoiding the problem of incomplete cleaning by using a single cleaning mode.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
