Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dry ice cleaning machine, in particular to a dry ice cleaning machine and a using method thereof. BACKGROUND

[0002] The dry ice cleaning technology uses solid carbon dioxide (dry ice) to impact the surface of an object under the acceleration of high-pressure airflow, and removes dirt through the triple effects of temperature difference peeling (low-temperature embrittlement of pollutants at-78.5℃), sublimation expansion (micro-explosion force generated by dry ice gasification), and kinetic energy impact, which has the advantages of no chemical residues, non-contact, and environmental protection. This technology has been gradually applied to the electronic manufacturing industry, such as cleaning of precision components such as PCBA circuit boards and flexible OLED panel wire areas, which can effectively remove flux residues, tin beads, and dust pollutants, and avoid scratches, corrosion, and VOC emission problems caused by traditional brushes or chemical solvents.

[0003] In related technologies, the dry ice cleaning method includes manual dry ice cleaning and dry ice cleaning device cleaning. Manual dry ice cleaning refers to that a worker holds a dry ice spray gun to clean a workpiece, and dry ice cleaning device cleaning refers to that a dry ice cleaning device is used to clean a workpiece. The existing dry ice cleaning device mainly includes a rack, a conveying mechanism, and a dry ice cleaning mechanism. During cleaning, the conveying mechanism conveys the workpiece to be cleaned to the dry ice cleaning mechanism, the dry ice cleaning mechanism cleans the workpiece to be cleaned, and after cleaning, the conveying mechanism conveys the workpiece to be discharged.

[0004] However, manual dry ice cleaning is not only low in efficiency, but also difficult to ensure the consistency of cleaning quality. When using a dry ice cleaning device, it is difficult to achieve accurate positioning and stable fixation of the workpiece because the dry ice cleaning device mainly relies on the conveying mechanism to position and fix the workpiece, which results in poor cleaning effect and low cleaning quality.

[0047] The present embodiment provides a dry ice cleaning machine, which refers to Figures 1-13 , comprising a machine body 100, an upper conveying line 10 and a lower conveying line 20 arranged on the machine body 100, a carrier 30 arranged on the upper conveying line 10 for carrying a workpiece 40, a positioning and lifting mechanism 50 arranged on the upper conveying line 10, a dry ice cleaning mechanism 60 located above the positioning and lifting mechanism 50, and a transfer carrier mechanism 70 arranged between the upper conveying line 10 and the lower conveying line 20.

[0048] In the present embodiment, the upper feeding port 101 and the lower feeding port 102 are located on the same side of the machine body 100, and in other embodiments, the upper feeding port 101 and the lower feeding port 102 can be arranged on different sides or other positions of the machine body 100 according to actual conditions, which is not limited here.

[0049] The feeding conveying line 10 is used to convey the carrier 30 carrying the workpiece 40 to the positioning and lifting mechanism 50, and the discharging conveying line 20 is used to output the workpiece 40 after cleaning. The feeding conveying line 10 and the discharging conveying line 20 are arranged in parallel, and the starting end of the feeding conveying line 10 and the ending end of the discharging conveying line 20 are located at the feeding port 101 and the discharging port 102 respectively. The ending end of the feeding conveying line 10 and the starting end of the discharging conveying line 20 are both located in the cavity.

[0050] It should be noted that in the embodiment, the workpiece 40 is a carrier plate, and in other embodiments, the workpiece 40 can also be other articles. The workpiece 40 is fixedly arranged on the carrier 30, and the carrier 30 and the workpiece 40 are synchronously moved without separation during the processes of feeding, positioning, cleaning, transferring and discharging.

[0051] The positioning and lifting mechanism 50 is used to position and fix the carrier 30, the dry ice cleaning mechanism 60 is used to clean the workpiece 40 positioned and fixed by the positioning and lifting mechanism 50, and the transfer mechanism 70 is used to synchronously transfer the carrier 30 and the workpiece 40 at the ending end of the feeding conveying line 10 to the discharging conveying line 20, so as to realize the transfer and normal discharging of the product.

[0052] During cleaning, the carrier 30 carrying the workpiece 40 is first placed on the feeding conveying line 10, and the carrier 30 is conveyed to the positioning and lifting mechanism 50 by the feeding conveying line 10. The positioning and lifting mechanism 50 positions and fixes the carrier 30, and then the dry ice cleaning mechanism 60 cleans the workpiece 40 on the carrier 30. After cleaning is completed, the positioning and lifting mechanism 50 returns to the initial state, so that the carrier 30 returns to the feeding conveying line 10. When the carrier 30 is conveyed to the ending end of the feeding conveying line 10, the transfer mechanism 70 transfers the carrier 30 at the ending end of the feeding conveying line 10 to the discharging conveying line 20. Finally, the discharging conveying line 20 outputs the carrier 30 for discharging, so as to complete the processes of feeding, positioning, cleaning, transferring and discharging of the workpiece 40, and realize the automatic cleaning of the workpiece 40.

[0053] In addition, in order to improve the cleaning effect and prevent the dry ice from splashing during cleaning, the cavity of the machine body 100 is provided with a cleaning cover 103, and the positioning and lifting mechanism 50, the dry ice cleaning mechanism 60, the ending end of the feeding conveying line 10, the starting end of the discharging conveying line 20 and the transfer mechanism 70 are all accommodated in the cleaning cover 103.

[0054] In some preferred embodiments, the machine body 100 is further provided with a waste cavity 104, and the waste cavity 104 is provided with a blower 105. The blower 105 is located below the cleaning cover 103, and the bottom side of the cavity corresponding to the cleaning cover 103 is communicated with the waste cavity 104, so as to suck the residues and residual glue falling during cleaning into a preset position by the blower 105.

[0055] Further, the positioning and jacking mechanism 50 comprises a first positioning frame 51 fixed on the machine body 100, a positioning plate 52 installed on the first positioning frame 51, a jacking plate 53 arranged on the first positioning frame 51 and below the positioning plate 52, and a jacking cylinder 54 for driving the jacking plate 53, wherein the positioning plate 52 is above the feeding conveying line 10, a gap is formed between the positioning plate 52 and the feeding conveying line 10 for the carrier 30 carrying the workpiece 40 to pass through, the positioning plate 52 is provided with a through hole 521 matched with the workpiece 40, and the jacking cylinder 54 is used to drive the jacking plate 53 to vertically lift relative to the positioning frame, so that the jacking plate 53 can jack up the carrier 30 in the gap, so that the workpiece 40 on the carrier 30 passes through the through hole 521 of the positioning plate 52 and at least partially protrudes from the upper surface of the positioning plate 52.

[0056] It can be understood that when the feeding conveying line 10 delivers the carrier 30 carrying the workpiece 40 into the gap between the jacking plate 53 and the feeding conveying line 10, the jacking plate 53 is driven to rise by the jacking cylinder 54, and when the carrier 30 is jacked up by the jacking plate 53, the workpiece 40 passes through the through hole 521 and at least partially protrudes from the top surface of the positioning plate 52, so as to realize accurate positioning of the workpiece 40. Not only the accuracy of positioning is improved, but also the shaking or mispositioning of the workpiece 40 during cleaning is effectively avoided, so as to ensure the consistency and stability of the cleaning effect.

[0057] It should be noted that the feeding conveying line 10 and the discharging conveying line 20 have the same structure, both of which comprise two symmetrical and parallel conveying belts with a certain spacing therebetween, the width of the carrier 30 is greater than the spacing between the two conveying belts, so that the two conveying belts can convey the carrier 30, and the width of the jacking plate 53 is less than the spacing, so that the jacking plate 53 can pass through the gap upward and jack up the carrier 30.

[0058] Further, the positioning and jacking mechanism 50 further comprises a second positioning frame 55 fixed on the machine body 100, an infeed sensor 56 arranged on the second positioning frame 55, and a cleaning blocking assembly 57 arranged on the second positioning frame 55, the second positioning frame 55 is located on the side of the first positioning frame 51 facing the transfer mechanism 70, the infeed sensor 56 is used to sense whether the carrier 30 enters the gap between the feeding conveying line 10 and the positioning plate 52, and the cleaning blocking assembly 57 is used to block the carrier 30 entering the gap, so that the jacking plate 53 can smoothly jack up the carrier 30.

[0059] It can be understood that when the carrier 30 is conveyed by the feeding conveying line 10 to a position close to the positioning plate 52, the feeding sensor 56 can sensitively sense the presence of the carrier 30 and then send a signal. At this time, the cleaning blocking assembly 57 quickly responds to the carrier 30 and performs moderate blocking to ensure that the carrier 30 does not continue to move forward or deviate during the lifting process of the lifting plate 53, thereby enhancing the stability of the lifting process and further improving the positioning accuracy of the workpiece 40, laying a solid foundation for the subsequent dry ice cleaning step.

[0060] Further, the cleaning blocking assembly 57 includes a mounting plate 571 fixedly arranged on the second positioning plate 52, a blocking bracket 572 arranged on the mounting plate 571, a blocking rod 573 hingedly connected to the blocking bracket 572, a blocking wheel 574 arranged on the blocking rod 573, and a cleaning blocking cylinder 575 for driving the blocking rod 573 to rotate relative to the blocking bracket 572 to enable the blocking wheel 574 to block the carrier 30.

[0061] When the feeding sensor 56 senses that the carrier 30 is positioned in the gap between the positioning plate 52 and the feeding conveying line 10, the cleaning blocking cylinder 575 acts and drives the blocking rod 573 to rotate relative to the blocking bracket 572, thereby driving the blocking rod 573 to rotate and enabling the blocking wheel 574 on the blocking rod 573 to block the carrier 30.

[0062] It should be noted that when the blocking wheel 574 abuts against the outside of the carrier 30 and blocks the carrier 30, at this time the feeding conveying line 10 will stop running, and at the same time the lifting plate 53 starts to lift the carrier 30 to a predetermined height.

[0063] In some preferred embodiments, the feeding conveying line 10 and the discharging conveying line 20 are further provided with a feeding blocking assembly 11 and a discharging blocking assembly 21. The feeding blocking assembly 11 and the discharging blocking assembly 21 are located outside the cleaning cover 103, and the feeding blocking assembly 11 and the discharging blocking assembly 21 have the same structure as the cleaning blocking assembly 57. The feeding blocking assembly 11 is used to block the carrier 30 on the feeding conveying line 10, and the discharging blocking assembly 21 is used to block the carrier 30 on the discharging conveying line 20. When the feeding conveying line 10 conveys the carrier 30 to the positioning and lifting mechanism 50 inside the cleaning cover 103, the feeding blocking assembly 11 blocks the carrier 30 outside the cleaning cover 103 to prevent the situation that two or more carriers 30 enter the cleaning cover 103 at the same time. When the discharging conveying line 20 conveys the carrier 30 out of the cleaning cover 103, the discharging blocking assembly 21 blocks the carrier 30 to prevent the situation that multiple carriers 30 are conveyed to the discharging port 102 at the same time, causing the discharging port 102 to be blocked.

[0064] In addition, the lower part of the feeding conveying line 10 is also provided with an FRID detector 12, which is located between the feeding opening 101 and the feeding blocking assembly 11, and the detection end of the FRID detector 12 is upwardly arranged, and the FRID detector 12 is used for detecting and identifying the carrier 30, so as to ensure that each carrier 30 is strictly authenticated before entering the cleaning process.

[0065] Further, the dry ice cleaning mechanism 60 includes a dry ice cleaning support 61 fixed on the rack, a dry ice cleaning spray gun 62 arranged on the dry ice cleaning support 61, and a three-axis moving module 63 for driving the dry ice cleaning spray gun 62 to move.

[0066] The dry ice cleaning spray gun 62 is used for spraying high-speed and uniform dry ice particles to the surface of the workpiece 40, and the three-axis moving module 63 is responsible for controlling the accurate movement of the dry ice cleaning spray gun 62 in three-dimensional space, so as to realize the overall cleaning of the surface of the complex workpiece 40. In addition, the dry ice cleaning mechanism 60 is also equipped with an intelligent control system, which can automatically adjust the spraying speed and spraying amount of the dry ice according to the material, size and cleaning requirement of the workpiece 40, so as to achieve the best cleaning effect. Since the dry ice cleaning spray gun 62 and the three-axis moving module 63 are conventional technical means in the field and are not the improvement points of the present application, they will not be described in detail in the present application.

[0067] Further, the transfer mechanism 70 includes a first lifting seat 71 arranged at the end of the feeding conveying line 10 for lifting the carrier 30 relative to the feeding conveying line 10, a second lifting seat 72 arranged at the beginning of the discharging conveying line 20 for receiving the carrier 30, a transfer assembly 73 arranged between the feeding conveying line 10 and the discharging conveying line 20 and used for transferring the carrier 30 on the first lifting seat 71 to the second lifting seat 72, and a first lifting cylinder 74 and a second lifting cylinder 75 respectively used for driving the first lifting seat 71 and the second lifting seat 72 to vertically lift.

[0068] When the carrier 30 is conveyed to the end of the feeding conveying line 10, the first lifting cylinder 74 drives the first lifting seat 71 to lift the carrier 30, and then the transfer assembly 73 starts to smoothly transfer the carrier 30 from the first lifting seat 71 to the second lifting seat 72. Then, the second lifting cylinder 75 drives the second lifting seat 72 to descend, and places the carrier 30 on the discharging conveying line 20, completing the whole transfer process. Not only the cleaning efficiency is improved, but also the stability and safety of the carrier 30 in the transfer process are ensured.

[0069] Further, the transfer assembly 73 comprises a transfer track 731 arranged at the end of the feeding conveying line 10 and the start of the discharging conveying line 20, a push plate 732 arranged above the transfer track 731, and a transfer cylinder 733 for driving the push plate 732 to move back and forth between the feeding conveying line 10 and the discharging conveying line 20, so as to push the carrier 30 on the first lifting seat 71 to the second lifting seat 72 through the transfer track 731.

[0070] When the first lifting seat 71 lifts the carrier 30, the push plate 732 moves above the first lifting seat 71 and gently pushes the carrier 30 onto the transfer track 731. Then, the push plate 732 continues to move along the transfer track 731 and stably pushes the carrier 30 onto the second lifting seat 72. The whole transfer process is stable and fast, which ensures the stability and safety of the carrier 30 during the transfer process. Meanwhile, the design of the transfer track 731 makes the transfer path more direct and efficient, further improving the cleaning efficiency. Compared with the traditional mechanical hand transfer mode, the transfer mechanism 70 of the present application has a compact structure and occupies a small space, which is suitable for various production environments and reduces the production cost.

[0071] Further, the dry ice cleaning machine provided by the present application further comprises a control mechanism 80, and the feeding conveying line 10, the discharging conveying line 20, the positioning and lifting mechanism 50, the dry ice cleaning mechanism 60, and the transfer mechanism 70 are electrically connected with the control mechanism 80, so as to control the cooperative work of the above-mentioned mechanisms through the control mechanism 80, and realize the automatic cleaning of the workpiece 40.

[0072] The present application also provides a use method of the dry ice cleaning machine, which is based on the dry ice cleaning machine as described above, and comprises the following steps:

[0073] Step 101, placing the carrier 30 carrying the workpiece 40 on the feeding conveying line 10 through the feeding opening 101, to complete the feeding of the workpiece 40;

[0074] Step 102, conveying the carrier 30 and the workpiece 40 to the positioning and lifting mechanism 50 through the feeding conveying line 10, positioning and lifting the carrier 30 by the positioning and lifting mechanism 50, so that the workpiece 40 on the carrier 30 passes through the through hole 521 of the positioning plate 52 and at least partially protrudes from the upper surface of the positioning plate 52;

[0075] Step 103, cleaning the workpiece 40 by the dry ice cleaning mechanism 60, and after the cleaning is completed, lowering the carrier 30 by the positioning and lifting mechanism 50, so that the carrier 30 returns to the feeding conveying line 10;

[0076] Step 104, the loading conveying line 10 conveys the carrier 30 to the end of the loading conveying line 10, the transfer mechanism 70 transfers the carrier 30 to the unloading conveying line 20, and the unloading conveying line 20 conveys the carrier 30 to the unloading port 102, thereby completing the unloading of the workpiece 40.

[0077] Further, between step 101 and step 102, there is also:

[0078] Step 1011, the loading blocking assembly 11 blocks the carrier 30 on the loading conveying line 10, the control mechanism 80 synchronously controls the loading conveying line 10 to stop running, and the RFID detector 12 scans the RFID information on the carrier 30 and transmits the RFID information to the control mechanism 80 to confirm the identity information and cleaning requirements of the carrier 30.

[0079] Step 1012, after the RFID information scanning and processing are completed, the control mechanism 80 controls the loading blocking assembly 11 to move away, the loading conveying line 10 continues to run and conveys the carrier 30 and the workpiece 40 to the positioning and lifting mechanism 50 in the cleaning cover 103 for subsequent operation.

[0080] In this embodiment, when the RFID detector 12 scans the RFID information on the carrier 30, the control mechanism 80 will first decode and verify the RFID information. If the RFID information matches the information in the preset database successfully, the control mechanism 80 will automatically adjust the parameter settings of the dry ice cleaning mechanism 60, such as cleaning time and dry ice spraying amount, according to the identity information and cleaning requirements of the carrier 30, to ensure the best cleaning effect and efficiency. If the RFID information is incorrect or missing, the control mechanism 80 will immediately issue an alarm and suspend the entire cleaning process, waiting for manual intervention and correction. Such design not only improves the automation degree of the cleaning process, but also greatly enhances the safety and accuracy of the operation.

[0081] Working principle: When the loading conveying line 10 receives the carrier 30 carrying the workpiece 40, it will automatically convey the carrier 30 and the workpiece 40 to the positioning and lifting mechanism 50. The positioning and lifting mechanism 50 precisely positions and fixes the carrier 30, and at the same time, the carrier 30 is lifted to ensure that the workpiece 40 can pass through the through hole 521 of the positioning plate 52 and at least partially protrude from the upper surface of the positioning plate 52. Then the dry ice cleaning mechanism 60 starts to clean the workpiece 40 efficiently and accurately. After cleaning, the positioning and lifting mechanism 50 returns to the initial position, and the carrier 30 is lowered to return to the loading conveying line 10. Then the loading conveying line 10 conveys the carrier 30 to the end, and the transfer mechanism 70 intervenes to smoothly transfer the carrier 30 to the unloading conveying line 20. Finally, the unloading conveying line 20 conveys the carrier 30 and the cleaned workpiece 40 to the unloading port 102, completing the entire cleaning process. This process fully embodies the characteristics of automation and intelligence, greatly improving the cleaning efficiency and quality.

Other modifications or equivalent replacements made by those skilled in the art to the technical solutions of the present application should be covered within the scope of the claims of the present application, as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
