Description

Technical Field

[0001] The present invention relates to the field of automation technology, and in particular to an automatic loading and unloading device and a single-side loading and unloading method. Background Art

[0002] Plasma cleaning machine is an advanced cleaning equipment that uses plasma technology to clean the surface of materials and can effectively remove organic and inorganic pollutants. This equipment is widely used in many fields such as semiconductor manufacturing, automobile manufacturing, medical and health care, optoelectronic products, plastic products, etc. The working principle of the plasma cleaning machine is to generate plasma in a vacuum chamber and use the high-energy active particles in the plasma to react physically or chemically with the surface of the material to achieve the cleaning effect. This cleaning method can not only remove tiny pollutants on the surface of objects, such as dust, oil, oxides, etc., but also improve the activity of the material surface and improve the bonding strength of subsequent processes.

[0045] The present invention proposes an automatic loading and unloading device, which aims to set a buffer zone between the conveyor belt and the cleaning machine so that a part of the sheets to be cleaned can be placed in advance without affecting the operation of the conveyor belt, thereby improving the production efficiency of the equipment. Figures 1 to 9 A schematic structural diagram of an embodiment of the automatic loading and unloading device provided by the present invention.

[0046] Please refer to Figures 1 to 9 The present invention proposes an automatic loading and unloading device 1000, including a base 1, a loading component 2 and an unloading component 3. The base 1 is provided with a material box 11 and a conveyor belt 12. The material box 11 is used to hold material sheets. The conveyor belt 12 is used to transport the material sheets in the material box 11 to the cleaning device. A placement rack 4 is provided at one end of the conveyor belt 12 away from the material box 11. The loading component 2 includes a first track 21, a first beam 22 and a material pushing mechanism 23. The first track 21 is provided on the base 1 and is provided along the extension direction of the conveyor belt 12. The first beam 22 is slidably provided on the first beam 22. A track 21, a first beam 22 is provided with a first driving mechanism 24 facing the base 1, a loading mechanism 23 is provided at the driving end of the first driving mechanism 24, and can be close to or away from the base 1, and the unloading component 3 includes a second track 31, a second beam 32 and a pushing and unloading mechanism 33. The second track 31 is provided on the base 1 and is arranged parallel to the first track 21. The second beam 32 is slidably provided on the second track 31. The second beam 32 is provided with a second driving mechanism 34 facing the base 1, and the pushing and unloading mechanism 33 is provided at the driving end of the second driving mechanism 34.

[0047] The technical solution of the present invention proposes an automatic loading and unloading device 1000 and a single-sided loading and unloading method using the automatic loading and unloading device 1000, wherein the automatic loading and unloading device 1000 includes a base 1, a material box 11 and a conveyor belt 12 arranged on the base 1, a loading component 2 and an unloading component 3, the material box 11 is used to hold material sheets, the conveyor belt 12 is used to transport the material sheets in the material box 11 to a cleaning device, and a placement rack 4 is provided at one end of the conveyor belt 12 away from the material box 11. The automated loading and unloading device 1000 has a loading state and a unloading state. In the loading state, the first driving mechanism 24 drives the loading mechanism 23 to descend, and the first beam 22 moves toward one end of the conveyor belt 12 to drive the loading mechanism 23 to push the material to be cleaned from the material box 11 to the conveyor belt 12, and then the conveyor belt 12 transports the material to the placement rack 4. The material to be cleaned is temporarily stored on the placement rack 4. After the cleaning of the material in the cleaning device is completed, the unloading mechanism 33 is controlled to push the material on the placement rack 4 into the cleaning device for cleaning. During this process, the conveyor belt 12 will continue to run without affecting the production efficiency of the equipment; in the unloading state, the second driving mechanism 34 drives the unloading mechanism 33 to descend, and the second beam 32 moves toward one end of the material box 11 to drive the unloading mechanism 33 to push the cleaned material from the placement rack 4 to the material box 11 via the conveyor belt 12 to complete the unloading.

[0048] The automatic loading and unloading device 1000 proposed in this case is mainly suitable for plasma cleaning machines, and of course it is not limited to use in other equipment that requires automatic loading and unloading of materials. The plasma cleaning machine greatly improves the cleaning efficiency of the sheets by loading the sheets to be cleaned and unloading the sheets that have been cleaned through the automatic loading and unloading device 1000. It should be noted that the plasma cleaning machine equipped with the automatic loading and unloading device 1000 can adjust its cleaning rate according to actual production needs, and provide deep cleaning and surface cleaning modes similar to washing machines. The time in each mode is different. The advantage of this design is that it provides flexibility and efficiency. By adjusting the plasma power, processing time and gas flow, the cleaning process can be optimized to adapt to different materials and pollutants, thereby improving production efficiency, reducing resource waste, and protecting materials from damage caused by excessive cleaning. This flexibility ensures that the equipment can adapt to various cleaning tasks, improve product quality, and provide rapid response to changes in the production process. The automatic loading and unloading device 1000 can also match the placement rack 4 of the corresponding storage space according to the cleaning efficiency of the plasma cleaning machine. If the cleaning machine has a high speed, the preparation station 1b needs to cache fewer pieces, and the distance of the placement rack 4 can be shortened accordingly; when the cleaning machine is in deep cleaning mode and runs slowly, the preparation station 1b can leave a longer area and appropriately extend the placement rack 4 to improve its caching capacity. The pieces will first be transported from the conveyor belt 12 to the placement rack 4, wait for synchronization on the placement rack 4, and then be pushed to the cleaning device by the pushing structure. In this way, there is no need for the conveyor belt 12 to maintain a high degree of consistency with the cleaning device, allowing the two to run at different speeds. Each link can independently optimize the running speed, improve overall production efficiency, and reduce downtime caused by mismatching between equipment.

[0049] In order to prevent the pushing mechanism from damaging the sheet when pushing the sheet, or from causing the sheet to fly out due to excessive thrust, or from causing the sheet to fail to be pushed out due to insufficient thrust, the automatic loading and unloading device 1000 further includes a pressure detection component, which includes a loading pressure sensor 25 provided on the first beam 22 and a unloading pressure sensor 35 provided on the second beam 32. For details, please refer to Figure 7 and Figure 8, a first motor 212 is provided on the first track 21, and the driving end of the first motor 212 can be connected to a transmission device such as a screw rod or a pulley to drive the first beam 22 to move along the first track 21; accordingly, in order to drive the second beam 32 to move, a second motor 311 is provided on the second track 31, and the driving end of the second motor 311 is externally connected to a transmission device. The loading pressure sensor 25 is electrically connected to the first motor 212, and the moving speed of the first beam 22 can be adjusted by controlling the motor speed, thereby adjusting the thrust of the loading mechanism 23; the unloading pressure sensor 35 is electrically connected to the second motor 311, and the thrust of the unloading mechanism 33 can be adjusted by controlling the speed of the second motor 311. The pressure detection component integrated in the automatic loading and unloading device 1000 includes pressure sensors for loading and unloading, which can monitor in real time the thrust of the push rod 232 of the material sheet during the loading process and the thrust of the dual-purpose push head 331 of the material sheet during the unloading process, thereby ensuring that the thrust is kept within the optimal range. This intelligent design helps prevent the blanks from being damaged during loading and unloading, and ensures that the thrust is not too small to affect efficiency. By precisely controlling the thrust, the stability and safety of the device are enhanced, while also reducing the possibility of human operating errors. This system can also adapt to blanks of different sizes and weights, providing flexible loading and unloading solutions, improving the level of automation and overall loading and unloading efficiency.

[0050] In actual production practice, the cyclic loading device loads a total of four material boxes 11 each time. In order to further improve the pushing rate, the pushing loading mechanism 23 includes a mounting plate 231 and a plurality of pushing rods 232 arranged on the mounting plate 231. For details, please refer to Figures 5 to 7 In this embodiment, there are four push rods 232, which are evenly spaced along the extension direction of the mounting plate 231. During the loading process, the four push rods 232 are respectively inserted into the four material boxes 11 to push the four sheets in the four receiving slots from the material boxes 11 to the conveyor belt 12. Accordingly, there are four conveyor belts 12, which are arranged to carry the sheets to be cleaned from the material boxes 11 corresponding to the four material boxes 11. Since the contact area between the end of the push rod 232 and the sheet is small, in order to prevent the thinner sheet from warping and deforming during the transportation process, so that the pushing position of the push rod 232 deviates and causes damage to the sheet, a contoured surface 233 is formed at the pushing end of each push rod 232. For details, please refer to Figure 6 The contoured surface 233 is designed according to the side wall of the sheet and is an inwardly concave V-shaped structural surface, so that it can match the shape of the sheet to position the sheet and prevent the sheet from being damaged under the thrust. Furthermore, a buffer layer can be provided at the contact end of the push rod 232, and the buffer contact end can be made of a flexible material such as silicone, rubber, etc., so that the flexible material is in direct contact with the sheet, thereby avoiding scratches and damage to the surface of the sheet.

[0051] When the push rod 232 contacts the material sheet, since the material sheet is in a stationary state and the push rod 232 is in a moving state, the push rod 232 will transfer the impulse to the material sheet to generate an impact force on the material sheet. The impact force generated by the movement of the push rod 232 is instantaneous, resulting in stress concentration on the surface and inside of the material sheet, which may exceed the yield strength of the material and cause deformation or rupture. In order to alleviate this problem, a guide rail 235 is provided on the side of the mounting plate 231 facing the base 1, and the push rod 232 is slidably arranged on the guide rail 235. Furthermore, the push rod 232 is provided with a first abutment block 238 facing the mounting plate 231, and the mounting plate 231 is provided with a second abutment block 236 facing the push rod 232. An elastic member 237 is provided between the first abutment block 238 and the second abutment block 236. For details, please refer to Figure 7 The deformation direction of the elastic member 237 is along the extension direction of the push rod. A section of the second abutment block 236 facing the first abutment block 238 is provided with a fixed column (not marked in the figure). The elastic member 237 is preferably a spring, and the spring is sleeved on the fixed column to achieve fixation. When one end of the push rod 232 contacts the sheet, the push rod 232 itself will retreat on the guide rail 235 due to the reaction force, and the spring is further compressed to be buffered. This design effectively absorbs the impact force, reduces damage to the sheet, and improves production efficiency and safety. Such a buffer mechanism not only protects the material from deformation and scratches, but also reduces wear on the equipment, extends the service life of the equipment, and improves the stability of the overall operation.

[0052] In order to improve the moving accuracy of the pushing and feeding mechanism 23 relative to the first crossbeam 22, the first crossbeam 22 is provided with two sleeves 221. For details, please refer to Figure 6 Correspondingly, the feeding mechanism 23 is provided with two guide rods 234, each guide rod 234 is movably arranged in a sleeve 221, and the two sleeves 221 are arranged on both sides of the first driving mechanism 24. The first driving mechanism 24 is preferably a cylinder, and it can also be a driving member such as a hydraulic cylinder. This is not limited in the present case. The driving end of the cylinder is connected to the mounting plate 231 of the feeding mechanism 23. When the feeding mechanism 23 is driven to rise and fall, the guide rod 234 will be limited in the sleeve 221, thereby ensuring that the feeding mechanism 23 will not deviate during the movement. The working efficiency and reliability of the entire mechanism are improved through precise guiding and limiting, and it is also convenient for maintenance and adjustment.

[0053] The automatic loading and unloading device 1000 proposed in this solution can load the sheets to be cleaned and unload the sheets after cleaning. The specific loading and unloading positions can be referred to in Figure 3First, the material box 11 is moved to the loading and unloading station 1a by the circulating loading device. The material box 11 contains the material to be cleaned. The material pushing mechanism 23 pushes the material to the conveyor belt 12. The conveyor belt 12 transports it to the preparation station 1b, and then the material pushing mechanism 33 pushes it to the cleaning device of the cleaning station 1c. After cleaning, the material pushing mechanism 33 can also run in reverse to push the cleaned material into the material box 11, that is, the loading and unloading station 1a to complete the unloading. In view of this, the material pushing mechanism 33 is provided with a plurality of dual-purpose push heads 331. For details, please refer to Figure 8 The dual-purpose pusher head 331 is L-shaped as a whole, and both ends of its lower part are pushing ends. One end is used to push the sheet to be cleaned into the cleaning station 1c, and the other end is used to push the cleaned sheet to the loading and unloading station 1a, so that the structure can achieve multi-functions.

[0054] In order to limit the movement of the first beam 22 and the second beam 32, the first track 21 and the second track 31 are both provided with a limit component 211. The limit component 211 cooperates and identifies with the matching parts on the first beam 22 and the second beam 32 to limit the movement of the first beam 22 and the second beam 32 so as not to overtravel. A mechanical limit component 211 can also be used to limit the first beam 22 and the second beam 32, but this case does not impose any restrictions on this.

[0055] The present invention further proposes a one-side loading and unloading method, which uses the above-mentioned automatic loading and unloading device 1000 to load and unload the sheet, and the one-side loading and unloading method includes the following steps: S1: obtaining a plurality of sheets, and loading the sheets into a material box 11; S2: obtaining a loading and unloading station 1a, and moving the material box 11 containing the sheets to the loading and unloading station 1a; S3: controlling the pushing mechanism 23 to push the sheets from the material box 11 to the conveyor belt 12;

[0056] S4: Get the preparation station 1b at one end of the conveyor belt 12, control the conveyor belt 12 to move and drive the sheet into the preparation station 1b; S5: Control the material pushing mechanism 33 to run forward to push the sheet from the preparation station 1b to the cleaning device; S6: Control the material pushing mechanism 33 to run reversely to push the cleaned sheet from the cleaning device to the conveyor belt 12; S7: Control the conveyor belt 12 to move and drive the sheet into the loading and unloading station 1a. Through this one-sided loading and unloading method, one-sided loading and unloading can be achieved while ensuring the production efficiency of the equipment, that is, the sheet to be cleaned enters from the left side, and the cleaned sheet also leaves from the left side. Compared with the traditional "left-in and right-out" production method, the production area required for the equipment is reduced, and the degree of integration of the equipment is also improved. The specific structure of the automatic loading and unloading device 1000 refers to the above embodiment. Since the one-sided loading and unloading method adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0057] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
