Description

Technical Field

[0001] This invention relates to the field of sandblasting cleaning technology, and in particular to a fully automatic cleaning system. Background Technology

[0002] After auxiliary product processing, the workpiece surface may have coating. To improve the quality of subsequent processes, sandblasting is typically used to clean the workpiece surface. This technology uses compressed air as a power source to propel abrasive particles at high speed onto the workpiece surface. Through impact and cutting action, the surface deposits are removed, resulting in a clean surface.

[0003] Common sandblasting equipment primarily relies on conveyor lines. Workpieces are loaded onto the conveyor line by robotic arms or manually and flow through the sandblasting area. To improve surface cleaning quality, sandblasting devices often have multiple nozzles arranged at different angles to spray the workpiece surface from multiple directions. Because the reaction forces generated by each nozzle are difficult to completely cancel each other out in space, the workpiece is highly susceptible to uneven combined impact forces during cleaning, causing it to sway, deflect, or even tip over on the conveyor line. This is especially problematic for smaller workpieces or those with a high center of gravity, where stability is extremely poor. This not only leads to uneven sandblasting coverage and affects the consistency of surface treatment, but in severe cases, it can even cause the workpiece to detach from the conveyor line, resulting in jamming or collision damage.

[0004] To avoid the aforementioned problems, existing technologies typically add guide baffles on both sides of the conveyor line width to restrict the lateral displacement of the workpiece. However, such structures can only constrain the lateral degree of freedom of the workpiece and cannot effectively limit its longitudinal movement, which still affects the cleaning quality of the workpiece.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automatic cleaning system that enables workpieces to flow more smoothly on the cleaning conveyor line, thereby improving cleaning quality.

[0007] The objective of this invention is achieved through the following technical solution: a fully automatic cleaning system, comprising: Cleaning equipment includes a cleaning conveyor line arranged along the X-axis for transporting workpieces and a cleaning device located on the conveying path of the cleaning conveyor line, wherein the cleaning conveyor line is provided with a first baffle on both sides in the Y-axis direction. A feeding device is connected to the input end of the cleaning conveyor line to feed the workpiece to be cleaned onto the cleaning conveyor line; The unloading equipment is connected to the output end of the cleaning conveyor line to receive the cleaned workpieces; Above the cleaning conveyor line and corresponding to the cleaning area of ​​the cleaning device, a pressing mechanism is provided. The pressing mechanism includes a first mounting frame, a pressing lifting module, and a pressure roller. The first mounting frame has a mounting shaft that is axially parallel to the Y-axis. At least one mounting shaft is arranged side by side along the X-axis. The pressure rollers are fitted onto the mounting shafts one by one and are axially limited to the mounting shafts. The inner diameter of the pressure rollers is larger than the outer diameter of the mounting shafts to form a radial floating gap. The pressure lifting module is connected to the first mounting frame and is adapted to drive the first mounting frame to descend along the Z-axis so that the pressure rollers press against the top of the workpiece.

[0008] Furthermore, the radial floating gap between the pressure roller and the mounting shaft allows the pressure roller to bear the weight of the mounting shaft when not in operation, and to press against the top of the workpiece by its own weight under the drive of the pressure lifting module.

[0009] Furthermore, the first mounting bracket includes: The main body of the mounting frame is connected to the pressure lifting module via a transmission. The support includes a mounting plate and a mounting shaft. The mounting plate is fixed to the bottom of the mounting frame body and two plates are arranged opposite each other along the Y-axis. The mounting shaft is connected to one of the mounting plates. The pressure roller is axially limited between the two mounting plates, and the bottom of its rim protrudes from the bottom of the mounting plate. The supports are arranged side by side along the X-axis, and each support includes at least one mounting shaft arranged side by side along the X-axis.

[0010] Furthermore, the first baffles on both sides have hollowed-out areas in the cleaning area of ​​the cleaning conveyor line. When the workpiece flows through the hollowed-out areas, the side of the workpiece in the Y-axis direction can be exposed for spraying treatment by the cleaning device.

[0011] Furthermore, the cleaning equipment includes: The outer casing, the cleaning conveyor line, the cleaning device, the first baffle and the pressing mechanism are all housed within the outer casing; A collection hopper, housed within the outer casing and located below the cleaning conveyor line, is used to collect the cleaning medium sprayed from the cleaning device. A circulation system is connected to the cleaning device and the collection hopper respectively. The circulation system is adapted to deliver the cleaning medium to the cleaning device and to recover and filter the cleaning medium in the collection hopper. The cleaning device includes two spraying mechanisms located on both sides of the cleaning conveyor line in the Y-axis direction. Each spraying mechanism includes at least one upper spray head assembly and one lower spray head assembly. The upper spray head assembly is arranged inclined downwards, and the lower spray head assembly is arranged inclined upwards. The two spraying mechanisms work together to clean the workpiece on both sides and the top side in the Y-axis direction.

[0012] Furthermore, the two sets of spraying mechanisms are staggered in the X-axis direction.

[0013] Furthermore, the feeding device includes: The first tray dispensing device stores several first trays containing workpieces to be cleaned and is able to dispense the first trays one by one. A material tray transfer device is used to receive the first material tray issued by the first tray issuing device and to sequentially transfer the first material tray to the first position and the second position. A transfer device is used to transfer the workpiece in the first tray at the first position to the input end of the cleaning conveyor line; A first receiving device is used to recycle the empty first tray in the second position.

[0014] Furthermore, the material tray transfer device includes a first material tray transfer line and a first transfer platform arranged along the Y-axis direction. The first material tray transfer line is connected to the first tray issuing device to drive the first material tray to the first position. The first transfer platform is located below the first material tray transfer line. The material transfer device includes a first workpiece conveyor line and a first side push mechanism. The first workpiece conveyor line is arranged along the X-axis direction, with its input end located on one side of the first material tray transfer line in the X-axis direction, and its output end connected to the input end of the cleaning conveyor line. The first material tray has at least one storage compartment along the Y-axis direction, and each storage compartment has several workpieces placed side by side along the X-axis direction. When the first material tray is moved to the first position, the first transfer platform is adapted to lift the first material tray, the first side push mechanism is adapted to push the entire row of workpieces from the first material tray into the first workpiece conveyor line along the X-axis direction, and the first transfer platform is adapted to transfer the empty first material tray to the second position and place it in the first receiving device.

[0015] Furthermore, the feeding device includes: The second tray issuing device stores several empty second trays and can issue the second trays one by one to the third position; A material collection device is used to receive and transport the workpieces flowing out of the clean conveyor line. The material collection device is adapted to divide and collect the continuously flowing workpieces according to a preset number to form several groups of workpiece units. A conveying device is used to move each workpiece unit to the second tray at the third position; The second receiving device is used to receive the second tray after it is fully loaded with workpieces and transport it to the fourth position.

[0016] Furthermore, the material collection device includes a second workpiece conveyor line, an interception mechanism, and a third workpiece conveyor line. Both the second and third workpiece conveyor lines are arranged along the X-axis direction. The input end of the second workpiece conveyor line is connected to the output end of the cleaning conveyor line, and the input end of the third workpiece conveyor line is connected to the output end of the second workpiece conveyor line. The interception mechanism is located at the output end of the second workpiece conveyor line and is adapted to intercept or allow the workpiece to flow out of the second workpiece conveyor line, so that the third workpiece conveyor line receives a workpiece unit. The conveying device includes a second side-pushing mechanism, a transfer platform, and a conveying mechanism. The transfer platform is located on one side of the third workpiece conveying line in the Y-axis direction. The second side-pushing mechanism is adapted to push the workpiece unit to the transfer platform along the Y-axis direction. The conveying mechanism is adapted to grab the workpiece unit and convey it to the second tray at the third position.

[0017] Compared with the prior art, the present invention has the following beneficial effects: By setting a pressure-retaining mechanism above the cleaning conveyor line, the present invention can limit the workpiece in the Z-axis direction, effectively preventing the workpiece from moving longitudinally under the impact of the jet reaction force, thus improving the cleaning quality. Moreover, the pressure-retaining mechanism is a liftable structure, which can adapt to workpieces of different heights. The pressure-retaining mechanism includes a mounting shaft and a pressure roller sleeved outside the mounting shaft. The inner diameter of the pressure roller is larger than the outer diameter of the mounting shaft to form a radial floating gap, so that the pressure roller can adapt to the height tolerance of different workpieces by its own weight, ensuring that the holding force is moderate and uniform. In addition, the entire pressure-retaining mechanism has a simple structure, does not require a complex power source, and can achieve efficient pressure by its own weight, significantly improving the stability and maintenance convenience of the system. Furthermore, cleaning media does not easily accumulate at the pressure roller, ensuring that the pressure-retaining mechanism can operate reliably for a long time. Attached Figure Description

It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0043] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0044] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] Please see Figures 1 to 3 , Figure 5 and Figure 6As shown, a fully automatic cleaning system corresponding to a preferred embodiment of the present invention includes: a cleaning device 100, comprising a cleaning conveyor line 110 arranged along the X-axis for transporting workpieces 400, and a cleaning device 120 located on the conveying path of the cleaning conveyor line 110; the cleaning conveyor line 110 is provided with first baffles 130 on both sides in the Y-axis direction; a loading device 200 connected to the input end of the cleaning conveyor line 110 to load the workpieces 400 to be cleaned onto the cleaning conveyor line 110; and a unloading device 300 connected to the output end of the cleaning conveyor line 110 to receive the cleaned workpieces 400; wherein, above the cleaning conveyor line 110 and corresponding to the cleaning device 120... The cleaning area is equipped with a pressing mechanism 140, which includes a first mounting frame 141, a pressing lifting module 142, and a pressure roller 143. The first mounting frame 141 is fixed with a mounting shaft 1414 axially parallel to the Y-axis. At least one mounting shaft 1414 is arranged side by side along the X-axis. The pressure roller 143 is sleeved on the outside of the mounting shaft 1414 and axially limited to the mounting shaft 1414. Its inner diameter is larger than the outer diameter of the mounting shaft 1414 to form a radial floating gap. The pressing lifting module 142 is connected to the first mounting frame 141 and is adapted to drive the first mounting frame 141 to descend along the Z-axis so that the pressure roller 143 presses against the top of the workpiece 400.

[0046] This invention provides a pressure-retaining mechanism 140 above the cleaning conveyor line 110. The pressure-retaining mechanism 140 can limit the workpiece 400 in the Z-axis direction, effectively preventing longitudinal movement of the workpiece 400 under the impact of the jet reaction force, thus improving cleaning quality. Furthermore, the pressure-retaining mechanism 140 is a liftable structure, adaptable to workpieces 400 of different heights. The pressure-retaining mechanism 140 includes a mounting shaft 1414 and a pressure roller 143 sleeved outside the mounting shaft 1414. The inner diameter of the pressure roller 143 is larger than the outer diameter of the mounting shaft 1414, forming a radial floating gap. This allows the pressure roller 143 to adapt to the height tolerances of different workpieces 400 by its own weight, ensuring moderate and uniform holding force. In addition, the entire pressure-retaining mechanism 140 has a simple structure, requires no complex power source, and achieves efficient pressure using its own weight, significantly improving system stability and maintenance convenience. Moreover, cleaning media does not easily accumulate at the pressure roller 143, ensuring the pressure-retaining mechanism 140 can operate reliably for a long time.

[0047] Furthermore, the pressure roller 143 has a circular structure, and the radial floating gap between the pressure roller 143 and the mounting shaft 1414 allows the pressure roller 143 to be supported by the mounting shaft 1414 in the non-working state, and to press against the top of the workpiece 400 by its own weight under the drive of the pressure lifting module 142.

[0048] Specifically, the first mounting frame 141 includes a mounting frame body 1411 and a support 1412. The pressure lifting module 142 is an electric cylinder structure arranged along the Z-axis direction. The mounting frame body 1411 is connected to the pressure lifting module 142 for transmission, so that it can rise or fall along the Z-axis direction under the drive of the pressure lifting module 142. The support 1412 includes a mounting plate 1413 and a mounting shaft 1414. The mounting plate 1413 is fixed to the bottom of the mounting frame body 1411, and two plates are arranged opposite each other along the Y-axis direction. The mounting shaft 1414 is connected to one of the mounting plates 1413. The pressure roller 143 is axially limited between the two mounting plates 1413, and the bottom of its rim protrudes from the bottom of the mounting plate 1413 under its own weight to press against the workpiece 400.

[0049] Preferably, the cleaning area of ​​the cleaning device 120 extends along the X-axis direction to thoroughly clean the workpiece 400. Accordingly, in this embodiment, the mounting frame body 1411 extends along the X-axis direction to both sides of the cleaning area, and multiple supports 1412 are arranged side by side along the X-axis direction. Each support 1412 includes at least one mounting shaft 1414 arranged side by side along the X-axis direction, ensuring that the pressing area of ​​the pressing mechanism 140 can be adapted to the cleaning area. Preferably, a certain gap is left between the multiple pressure rollers 143 arranged side by side to prevent the pressure rollers 143 from obstructing each other when they float radially.

[0050] Furthermore, the cleaning conveyor line 110 has a chain-type transport structure, which makes it easier for the cleaning medium sprayed onto the cleaning conveyor line 110 to fall off the cleaning conveyor line 110. The cleaning conveyor line 110 is a known structure, and will not be described in detail here.

[0051] Reference Figure 3 and Figure 4 As shown, the cleaning equipment 100 includes a first width adjustment component 150, which is located below the cleaning conveyor line 110. A first baffle 130 is connected to the first width adjustment component 150. The first width adjustment component 150 can drive the first baffles 130 on both sides to move towards or away from each other to adjust the distance between the first baffles 130 and adapt to workpieces 400 of different sizes.

[0052] The first width adjustment assembly 150 includes a second mounting bracket 151 and a width adjustment module 152. The second mounting bracket 151 is movable along the Y-axis direction. There are two second mounting brackets 151, each connected to a different first baffle 130. The width adjustment module 152 is specifically an electric screw structure, whose output end is connected to the second mounting bracket 151 to drive the two first baffles 130 to move towards or away from each other along the Y-axis direction. The electric screw structure driving the first baffles 130 is a known structure, and will not be described further here.

[0053] Furthermore, the first baffles 130 on both sides have perforated areas 131 in the cleaning area of ​​the cleaning conveyor line 110, and the perforated areas 131 are formed through the Y-axis direction. When the workpiece 400 flows through the perforated area 131, the side of the workpiece 400 in the Y-axis direction can be exposed for spraying treatment by the cleaning device 120. Preferably, in the X-axis direction, the size of the perforated area 131 is smaller than the size of the workpiece 400 to prevent the workpiece 400 from falling out of the cleaning conveyor line 110 through the perforated area 131. Multiple perforated areas 131 can be arranged at intervals along the X-axis direction to improve the cleaning effect.

[0054] Furthermore, the cleaning device 120 includes two spraying mechanisms 121, which are respectively arranged on both sides of the cleaning conveyor line 110 in the Y-axis direction. The two spraying mechanisms 121 can cooperate to clean the workpiece 400 on both sides and the top side in the Y-axis direction. Each spraying mechanism 121 includes at least one upper nozzle assembly 122 and one lower nozzle assembly 123. The upper nozzle assembly 122 is arranged inclined downwards, and the lower nozzle assembly 123 is arranged inclined upwards. The two clean the workpiece 400 from different angles, which can effectively improve the cleaning quality.

[0055] Preferably, the two spraying mechanisms 121 are staggered in the X-axis direction to prevent the cleaning media sprayed by the two from interfering with each other. Correspondingly, the hollow areas 131 of the first baffles 130 on both sides are also staggered in the X-axis direction. In this embodiment, multiple sets of upper nozzle assembly 122 and lower nozzle assembly 123 can be arranged side by side along the X-axis direction to increase the cleaning area, so that the same workpiece 400 can be cleaned multiple times during its movement along the X-axis direction, ensuring that its surface is completely cleaned.

[0056] Both the upper nozzle assembly 122 and the lower nozzle assembly 123 include an adjusting bracket 124 and a nozzle 125 connected to the adjusting bracket 124. The adjusting bracket 124 can adjust the position and angle of the nozzle 125 at multiple positions to achieve optimal spraying. In this embodiment, since the first mounting bracket 141 is located above the cleaning conveyor line 110, the adjusting bracket 124 of the upper nozzle assembly 122 can be directly mounted on the first mounting bracket 141, thereby simplifying the installation structure of the upper nozzle assembly 122. Since the first width adjustment assembly 150 is located below the cleaning conveyor line 110, the adjusting bracket 124 of the lower nozzle assembly 123 can be directly mounted on the second mounting bracket 151, thereby simplifying the installation structure of the lower nozzle assembly 123.

[0057] In addition, refer to Figure 2As shown, the cleaning device 100 also includes a housing 160, a collection hopper 170, and a circulation system 180. The cleaning conveyor line 110, cleaning device 120, first baffle 130, pressing mechanism 140, first width adjustment assembly 150, and collection hopper 170 are all housed within the housing 160. The collection hopper 170 is positioned below the cleaning conveyor line 110 to collect the cleaning medium sprayed by the spraying mechanism 121. The circulation system 180 is connected to both the spraying mechanism 121 and the collection hopper 170 to transport the cleaning medium to the spraying mechanism 121 and to recover and filter the cleaning medium in the collection hopper 170. The recycling of the cleaning medium by the circulation system 180 is a well-known structure in the art, and its structure will not be described in detail here.

[0058] Furthermore, referring to Figure 7 As shown, the feeding equipment 200 includes a first dispensing device 210, a tray transfer device 220, a transfer device 230, and a first receiving device 240. The first dispensing device 210 stores a plurality of first trays 250 containing workpieces 400 to be cleaned, and can dispense the first trays 250 one by one. The tray transfer device 220 receives the first trays 250 dispensed by the first dispensing device 210 and sequentially transfers the first trays 250 to a first position and a second position. The transfer device 230 transfers the workpieces 400 in the first tray 250 at the first position to the input end of the cleaning conveyor line 110, and when the first tray 250 is empty, the tray transfer device 220 transfers the first tray 250 to the second position. The first receiving device 240 collects the empty first trays 250 at the second position.

[0059] Furthermore, referring to Figure 8 As shown, the first feeding device 210 includes a first material frame 211, a material frame lifting module 212, and a material tray feeding line 213. The material frame lifting module 212 is connected to the first material frame 211 in a transmission manner. The material frame lifting module 212 is a linear module arranged along the Z-axis direction, which can drive the first material frame 211 to rise and fall along the Z-axis direction.

[0060] The first material frame 211 has open sides on both sides in the Y-axis direction. Multiple sets of support assemblies 214 are spaced apart in the inner cavity of the first material frame 211 along the Z-axis direction. Each support assembly 214 includes two first support members 2141, which are at the same horizontal height and connected to both sides of the inner cavity of the first material frame 211 in the X-axis direction. A plurality of first material trays 250 can be loaded into the first material frame 211 from one of the open sides along the Y-axis direction and correspondingly supported on each support assembly 214. Preferably, in this embodiment, each support assembly 214 can support multiple first material trays 250, and the multiple first material trays 250 are arranged side-by-side along the Y-axis direction.

[0061] The material tray loading line 213 is a conventional belt conveyor line, arranged along the Y-axis. The material tray loading line 213 passes through the first material frame 211, which can rise to its initial position, placing the material tray loading line 213 below the bottom support assembly 214. This facilitates the loading of the first material tray 250 into the first material frame 211 by operators or robots. The two first support members 2141 of the support assembly 214 are located outside the material tray loading line 213 to prevent it from obstructing the lifting and lowering of the first material frame 211. When the first material frame 211 is fully loaded with the first material tray 250, the material frame lifting module 212 can drive the first material frame 211 to descend, so that the bottom first material tray 250 is placed on the material tray loading line 213. The material tray loading line 213 drives the first material tray 250 to move out of the first material frame 211 from the other open side of the first material frame 211 along the Y-axis direction and convey it to the material tray transfer device 220. Then the first material frame 211 can continue to descend, so as to continue to place the first material tray 250 on the material tray loading line 213.

[0062] Furthermore, referring to Figures 9 to 11 As shown, the tray transfer device 220 includes a first tray transfer line 221 and a first transfer platform 222. The first tray transfer line 221 is arranged along the Y-axis direction, and its input end is connected to the output end of the tray loading line 213 to receive the first tray 250 flowing out of the tray loading line 213 and transport it to a first position. The first transfer platform 222 is located below the first tray transfer line 221. When the first tray 250 is moved to the first position, the first transfer platform 222 is adapted to lift the first tray 250, and the transfer device 230 moves the workpiece 400 away from the first tray 250. After the first tray 250 is empty, the first transfer platform 222 is adapted to transfer the empty first tray 250 to a second position and place it in the first receiving device 240.

[0063] The material transfer device 230 includes a first workpiece conveyor line 231 and a first side-pushing mechanism 232. The first workpiece conveyor line 231 is arranged along the X-axis direction, with its input end located on one side of the first tray transfer line 221 in the X-axis direction, and its output end extending into the housing 160 to connect with the input end of the cleaning conveyor line 110. The first tray 250 has at least one storage compartment 251 along the Y-axis direction, and each storage compartment 251 has several workpieces 400 placed side by side along the X-axis direction. The storage compartment 251 is open on the side of the X-axis direction closest to the first workpiece conveyor line 231. When the first tray 250 is moved to the first position, the first transfer platform 222 is adapted to lift the first tray 250, so that the open side of one of the storage compartments 251 is connected to the input end of the first workpiece conveyor line 231. The first side-pushing mechanism 232 is adapted to push the entire row of workpieces 400 from the first tray 250 into the first workpiece conveyor line 231 along the X-axis direction, and then the first workpiece conveyor line 231 conveys the row of workpieces 400 to the cleaning conveyor line 110. When the first tray 250 is provided with multiple storage compartments 251, whenever a workpiece 400 in a storage compartment 251 is pushed away, the first transfer platform 222 can drive the first tray 250 to move along the Y-axis direction, so that another storage compartment 251 containing workpieces 400 is connected to the first workpiece conveyor line 231. After the first tray 250 is completely empty, the first transfer platform 222 is adapted to transfer the empty first tray 250 to the second position and place it in the first receiving device 240.

[0064] By adopting the above structure, the workpiece 400 can be efficiently and continuously transported to the cleaning conveyor line 110, thereby improving the feeding efficiency.

[0065] Furthermore, the first material tray transfer line 221 is a conventional belt conveyor line, which is provided with a first blocking member 2211 at the first position. When the first material tray 250 transfers to the first position, the first blocking member 2211 can block the first material tray 250 and keep it in the first position.

[0066] The first transfer platform 222 includes a first platform body 223, a first transfer module 224, and a platform lifting module 225. The first transfer module 224 is a linear module arranged along the Y-axis direction, and its output end is provided with a base 2241. The platform lifting module 225 is disposed on the base 2241 and is a linear cylinder arranged along the Z-axis direction. The first platform body 223 is connected to the platform lifting module 225 in a transmission manner. The first platform body 223 is adapted to descend along the Z-axis direction under the drive of the platform lifting module 225 so as not to obstruct the flow of the first material tray 250 on the first material tray transfer line 221, or to rise along the Z-axis direction to support the first material tray 250.

[0067] The first unit 223 includes a base plate 2231 and two support bars 2232 connected to the base plate 2231. The support bars 2232 are located on opposite sides of the base plate 2231 along the X-axis. The support bars 2232 extend beyond the base plate 2231 along the conveying direction of the first material tray conveyor line 221. The portion of the support bar 2232 outside the base plate 2231 supports the first material tray 250. A second blocking member 2233 is provided at the extended end of the support bar 2232. When the first unit 223 rises to carry the first material tray 250, the second blocking member 2233 can block the first material tray 250 in the conveying direction of the first material tray conveyor line 221.

[0068] Furthermore, the first workpiece conveyor line 231 is a conventional belt conveyor line, which has second baffles 233 on both sides in the Y-axis direction. The workpiece 400 flowing on the first workpiece conveyor line 231 is limited between the second baffles 233 on both sides to ensure that it flows into the cleaning conveyor line 110 in a preset posture.

[0069] The material transfer device 230 includes a second width adjustment component 234 that is pulsatorically connected to the second baffle 233. The second width adjustment component 234 can drive the second baffles 233 on both sides to move towards or away from each other along the Y-axis to adjust the distance between them and adapt to workpieces 400 of different sizes. The structure of the second width adjustment component 234 is similar to that of the first width adjustment component 150, and will not be described in detail here.

[0070] The first side-pushing mechanism 232 is located above the first material tray conveyor line 221, and includes a first side-pushing component 2321, a first side-pushing module 2322, and a first lifting drive component 2323. The first side-pushing module 2322 is a linear module arranged along the X-axis direction, and the first lifting drive component 2323 is a linear cylinder arranged along the Z-axis direction, which is drivenly connected to the first side-pushing module 2322. The first side-pushing component 2321 is drivenly connected to the first lifting drive component 2323. When the first material tray 250 flows to the first position, the first side-pushing component 2321 can descend under the drive of the first lifting drive component 2323 to correspond to the storage compartment 251. Then, the first side-pushing module 2322 drives the first side-pushing component 2321 to move along the X-axis direction to push the workpiece 400 in the storage compartment 251 into the first workpiece conveyor line 231.

[0071] Furthermore, referring to Figure 7 and Figure 10As shown, the first receiving device 240 includes a second tray conveyor line 241 and a first lifting platform 242. The second tray conveyor line 241 is located below the first tray conveyor line 221 and is a belt conveyor line arranged along the Y-axis. The first lifting platform 242 is an electric or pneumatic platform, which is correspondingly located at the second position. When the first platform 223 moves the first tray 250 to the second position, the first lifting platform 242 can rise through the clearance area between the two support bars 2232 and support the first tray 250 on the first platform 223. After the first platform 223 moves away from the second position, the first lifting platform 242 can lower the first tray 250 to place the first tray 250 on the second tray conveyor line 241, and then the second tray conveyor line 241 unloads the first tray 250.

[0072] In addition, refer to Figures 12 to 14 As shown, the first receiving device 240 also includes a receiving mechanism 243 connected to the output end of the second material tray transfer line 241. The receiving mechanism 243 is used to receive and stack the first material tray 250 output by the second material tray transfer line 241.

[0073] The closing mechanism 243 includes a frame 244, a roller line 245, a second lifting platform 246, and a closing cart 247. A storage cavity 2441 is formed inside the frame 244, and the roller line 245 is installed near the top of the storage cavity 2441. The roller line 245 is an inclined line with a high end and a low end in the Y-axis direction. The high end of the roller line 245 connects to the output end of the second tray transfer line 241. The first tray 250 flowing from the second tray transfer line 241 into the roller line 245 can move towards the low end of the roller line 245 under gravity. A third blocking member 2457 is provided at the low end of the roller line 245 to block the first tray 250 on the roller line 245.

[0074] The roller line 245 includes a base plate 2451, a first roller assembly 2452, a feeding drive 2453, and a second roller assembly 2454. The base plate 2451 is fixed to the inner wall of the storage cavity 2441. Two sets of first roller assemblies 2452 are mounted on the base plate 2451 and arranged opposite each other along the X-axis. The two sets of first roller assemblies 2452 cooperate to receive the first tray 250 flowing out from the second tray transfer line 241. Two sets of second roller assemblies 2454 are also arranged opposite each other along the X-axis and are connected to the lower end of the first roller assembly 2452. Both the first roller assembly 2452 and the second roller assembly 2454 include a roller plate 2455 and rollers 2456 rotatably spaced on the roller plate 2455. The height of each roller 2456 gradually decreases in the direction from one end of the roller line 245 near the second tray transfer line 241 to the other end. The third blocking member 2457 is connected to the substrate 2451. The first tray 250 flowing out from the first roller assembly 2452 can flow into the second roller assembly 2454 and is eventually blocked by the third blocking member 2457.

[0075] A feeding drive 2453 is disposed on the substrate 2451 and is a linear cylinder arranged along the X-axis. The feeding drive 2453 corresponds one-to-one with the second roller assembly 2454, and the output end of the feeding drive 2453 is connected to the roller plate 2455 of the second roller assembly 2454. The two second roller assemblies 2454 can move away from each other along the X-axis under the drive of the feeding drive 2453, so that the first tray 250 disengages from the second roller assembly 2454, or move closer together to support the first tray 250. Preferably, the substrate 2451 has a third baffle 2458 on the outer side of the first roller assembly 2452 and the second roller assembly 2454 to limit the first tray 250 in the X-axis direction.

[0076] The substrate 2451 has a hollow structure in the area between the two sets of second roller assemblies 2454. The second lifting platform 246 is located in the lower area between the two sets of second roller assemblies 2454. It can receive the first tray 250 that disengages from the second roller assemblies 2454 and gradually descend so that the first tray 250 gradually stacks on the second lifting platform 246. The second lifting platform 246 is an electric lifting platform to ensure its lifting accuracy.

[0077] The storage cavity 2441 is an openable and closable structure. When the storage cavity 2441 is opened, the closing carriage 247 can be pushed into the storage cavity 2441. The closing carriage 247 has a closing frame 2471. The bottom of the closing frame 2471 has a support structure. The top of the closing frame 2471 is open, and its side facing the second lifting platform 246 is also open. After the receiving cart 247 is pushed to the preset position of the storage cavity 2441, the second lifting platform 246 enters the receiving frame 2471 through the side of the receiving frame 2471. The top of the receiving frame 2471 is correspondingly located below the hollow structure. As the second lifting platform 246 descends, the first material trays 250 stacked on it can gradually move from the top of the receiving frame 2471 into the receiving frame 2471 until the second lifting platform 246 descends to the support structure of the receiving frame 2471. At this time, the receiving cart 247 is fully loaded and can be moved out of the storage cavity 2441 to facilitate the transfer of the first material trays 250.

[0078] Preferably, a hinge 248, such as a hinge, is provided between the substrate 2451 on the side away from the second tray transfer line 241 in the Y-axis direction and the storage cavity 2441, so that the substrate 2451 can rotate around the X-axis. The roller line 245 also includes a first adjustment drive 249, which is a linear cylinder. Its output end is hinged to the substrate 2451, and its main body is hinged to the inner wall of the storage cavity 2441. The first adjustment drive 249 can push the substrate 2451 to rotate so as to adjust the inclination of the roller line 245. When the first tray 250 needs to be transferred, the output end of the first adjusting drive 249 extends to increase the inclination of the roller line 245, so as to better receive and transfer the first tray 250. When the first tray 250 needs to be lowered to the second lifting platform 246, the output end of the first adjusting drive 249 retracts to reduce the inclination of the roller line 245, so that the first tray 250 can be placed more stably on the second lifting platform 246.

[0079] Furthermore, referring to Figure 15 and Figure 16 As shown, the unloading equipment 300 includes a second dispensing device 310, a collecting device 320, a conveying device 330, and a second receiving device 340. The first dispensing device 310 stores a plurality of empty second trays 350 and is capable of dispensing the second trays 350 one by one to a third position. The collecting device 320 is used to receive and convey the workpieces 400 flowing out of the clean conveyor line 110. The collecting device 320 is adapted to divide and collect the continuously flowing workpieces 400 according to a preset quantity to form a plurality of workpiece units. The conveying device 330 is used to convey the workpiece units to the second trays 350 at the third position. The second receiving device 340 is used to receive the second trays 350 after they are fully loaded with workpieces 400 and convey them to a fourth position for removal by operators or robots.

[0080] Furthermore, referring to Figures 16 to 18 As shown, the second pallet dispensing device 310 includes a second material frame 311, a lowering mechanism 312, a second transfer platform 313, and a fixing mechanism 314. The top and bottom of the second material frame 311 are open structures, allowing empty second material trays 350 to be stacked into the second material frame 311 from the top. The second material tray 350 has a frame structure with a flange 351 around its top perimeter. Two sets of lowering mechanisms 312 are located on either side of the second material frame 311 along the Y-axis. The lowering mechanisms 312 support the flange 351 of the bottommost second material tray 350 to support the entire stack of second material trays 350. The lowering mechanism 312 includes a second support member 3121, a first lowering drive member 3122, and a second lowering drive member 3123. The first lowering drive 3122 is a linear cylinder arranged along the Z-axis direction. The second lowering drive 3123 is connected to the first lowering drive 3122 in a transmission manner. The second lowering drive 3123 is a linear cylinder arranged along the Y-axis direction and is connected to the second support 3121 in a transmission manner. The second support 3121 can move along the Z-axis and Y-axis directions under the drive of the first lowering drive 3122 and the second lowering drive 3123.

[0081] The second transfer platform 313 is located below the second material frame 311 and is arranged along the X-axis. The second transfer platform 313 includes a second platform 3131 and a second transfer module 3132 that is drivenly connected to the second platform 3131. The second transfer module 3132 is a linear module arranged along the X-axis and can drive the second platform 3131 to move directly below the second material frame 311 or to a third position.

[0082] When the second platform 3131 is directly below the second material frame 311, the lowering mechanism 312 can lower the bottom second material tray 350 onto the second platform 3131. Specifically, the first lowering drive member 3122 can drive the second support member 3121 to descend so that the entire stack of second material trays 350 is supported on the second platform 3131. Then, the second lowering drive member 3123 drives the second support member 3121 to move away from the bottom second material tray 350, and moves down to the flange 351 of the second material tray 350 above the bottom second material tray 350 under the driving cooperation of the first lowering drive member 3122, so as to lift and support the other second material trays 350 except for the bottom second material tray 350, so that the bottom second material tray 350 is separated and placed on the second platform 3131.

[0083] The second unit 3131, driven by the second transfer module 3132, moves the lowermost second tray 350 to the third position. The fixing mechanism 314 is located at the third position. When the second tray 350 is moved to the third position, the fixing mechanism 314 clamps the second tray 350, thus completing the tray unloading. There are two sets of fixing mechanisms 314, arranged opposite each other along the Y-axis. A space is formed between the two sets of fixing mechanisms 314 to accommodate the second tray 350. When the second tray 350 is placed in this space, the two sets of fixing mechanisms 314 cooperate to clamp the second tray 350. The fixing mechanism 314 is specifically a cylinder-driven clamping structure, which is a known structure and will not be described further here.

[0084] Furthermore, referring to Figure 15 , Figures 19 to 21 As shown, the material collection device 320 includes a second workpiece conveyor line 321, an interception mechanism 322, and a third workpiece conveyor line 323. Both the second and third workpiece conveyor lines 321 and 323 are belt conveyors arranged along the X-axis. The input end of the second workpiece conveyor line 321 extends into the housing 160 to connect with the output end of the cleaning conveyor line 110. The input end of the third workpiece conveyor line 323 connects with the output end of the second workpiece conveyor line 321. The interception mechanism 322 is located at the output end of the second workpiece conveyor line 321 and is adapted to intercept or allow workpieces 400 to flow out of the second workpiece conveyor line 321, so that after the third workpiece conveyor line 323 receives a preset number of workpieces 400 to form a workpiece unit, it intercepts the workpieces 400 at the second workpiece conveyor line 321.

[0085] The conveying device 330 includes a second side-pushing mechanism 331, a transfer table 332, and a conveying mechanism 333. The transfer table 332 is located on one side of the third workpiece conveyor line 323 in the Y-axis direction. The second side-pushing mechanism 331 is adapted to push the workpiece unit to the transfer table 332 along the Y-axis direction. The conveying mechanism 333 is adapted to grab the workpiece unit and convey it to the second tray 350 in the third position.

[0086] Specifically, the cleaned workpieces 400 sequentially flow through the cleaning conveyor line 110 and the second workpiece conveyor line 321 into the third workpiece conveyor line 323. When the third workpiece conveyor line 323 receives a preset number of workpieces 400 (i.e., one workpiece unit), the intercepting mechanism 322 intercepts the workpieces 400 on the second workpiece conveyor line 321 to prevent them from continuing to flow into the third workpiece conveyor line 323. Then, the second side-pushing mechanism 331 pushes the workpieces 400 on the third workpiece conveyor line 323 into the transfer table 332. The conveying speed of the second workpiece conveyor line 321 can be set to a slower speed, while the conveying speed of the third workpiece conveyor line 323 can be set to a faster speed to prevent congestion caused by prolonged interception of the workpieces 400 on the second workpiece conveyor line 321. Furthermore, the second workpiece conveyor line 321 can also be composed of multiple independently operating lines connected together. By adjusting the flow speed between each line, blockage of the workpieces 400 on the second workpiece conveyor line 321 after interception can be prevented.

[0087] Furthermore, the second workpiece conveyor line 321 is provided with fourth baffles 324 on both sides of the Y-axis to block the workpieces 400. The fourth baffles 324 are adjustable in the Y-axis direction, and the two fourth baffles 324 can be adjusted towards or away from each other along the Y-axis to accommodate workpieces 400 of different sizes. This will not be described in detail here. The third workpiece conveyor line 323 has no obstructions on both sides of the Y-axis direction, and its bearing surface is flush with the platform of the transfer table 332, so that the second side-pushing mechanism 331 can push the workpieces 400 from the third workpiece conveyor line 323 to the transfer table 332.

[0088] The interception mechanism 322 includes a first support 3221, a first clamping drive 3222, and a first clamping member 3223. The first clamping drive 3222 is disposed on the first support 3221 and is a gripper cylinder with two output ends capable of moving towards or away from each other along the Y-axis. There are two first clamping members 3223, which are respectively connected to different output ends of the first clamping drive 3222. The first clamping members 3223 are located on both sides of the second workpiece conveyor line 321 in the Y-axis direction. When the workpiece 400 flows to the output end of the second workpiece conveyor line 321, the two first clamping members 3223 can cooperate to clamp the workpiece 400 on both sides of the Y-axis direction to block the workpiece 400.

[0089] Preferably, the interception mechanism 322 further includes a second adjustment drive member 3224 disposed on the first bracket 3221, which is an electric cylinder or a pneumatic cylinder arranged along the X-axis direction, and the first clamping drive member 3222 is pultrusively connected to the second adjustment drive member 3224. The second adjustment drive member 3224 can adjust the position of the first clamping member 3223 in the X-axis direction so that the first clamping member 3223 is in the optimal clamping position.

[0090] In addition, the material collection device 320 includes an air blowing mechanism 325 located on the conveying path of the second workpiece conveying line 321. The air blowing mechanism 325 can blow air onto the surface of the workpiece 400 to remove sand and dust from the surface of the workpiece 400 and improve the subsequent cleanliness.

[0091] Further, the second side-pushing mechanism 331 includes a second support 3311, a second side-pushing module 3312, a second lifting drive 3313, a second clamping drive 3314, and a second side-pushing member 3315. The second support 3311 is located at the output end of the third workpiece conveyor line 323. The second side-pushing module 3312 is mounted on the second support 3311 and is a linear module arranged along the Y-axis. The second lifting drive 3313 is a linear cylinder arranged along the Z-axis and is drive-connected to the second side-pushing module 3312. The second clamping drive 3314 is a gripper cylinder and is drive-connected to the second lifting drive 3313. The second clamping drive 3314 has two output ends capable of moving towards or away from each other along the Y-axis. There are two second side-pushing members 3315, each connected to a different output end of the second clamping drive 3314. The second side pusher 3315 is a long strip-shaped structure with its length direction parallel to the X-axis direction, and a space for accommodating the workpiece unit is formed between the two second side pushers 3315.

[0092] Initially, the two second side pushers 3315 descend to the third workpiece conveyor line 323 under the drive of the second lifting drive 3313. The workpieces 400 on the second workpiece conveyor line 321 can move one by one into the space between the two second side pushers 3315 along the X-axis direction. When a preset number of workpieces 400 enter the clamping area of ​​the second side pushers 3315, the second side pushers 3315 move towards each other under the drive of the second clamping drive 3314 to clamp the workpieces 400. Then, the second side pushers 3315 move the workpieces 400 to the transfer table 332 under the drive of the second side pusher module 3312. Finally, the second side pushers 3315 release the workpieces 400 and rise to return to the third workpiece conveyor line 323, and then descend to continue receiving workpieces 400.

[0093] Preferably, the second support 3311 is provided with a first alignment component 334, which includes an alignment drive 3341 and an alignment component 3342. The alignment drive 3341 is a linear cylinder arranged along the X-axis direction, and the alignment component 3342 is drively connected to the alignment drive 3341. The alignment component 3342 corresponds to the open side of the clamping area away from the second workpiece conveyor line 321, and is adapted to extend into the clamping area under the drive of the alignment drive 3341 to push the workpiece unit so that the workpieces 400 of the workpiece unit are close together.

[0094] Preferably, the transfer table 332 is provided with a second alignment component 335, the structure of which is similar to that of the first alignment component 334, and it is also arranged along the X-axis direction. When the second side pusher 3315 pushes the workpiece unit to the transfer table 332, the second alignment component 335 corresponds to the open side of the clamping area near the second workpiece conveyor line 321, so as to push the workpiece unit along the X-axis direction, so that each workpiece 400 is close together, which facilitates the subsequent handling by the handling mechanism 333.

[0095] Furthermore, the transfer platform 332 and the fixed mechanism 314 are located on the same straight line parallel to the Y-axis to simplify the transport path of the transport mechanism 333. (Refer to...) Figure 22 As shown, the conveying mechanism 333 includes a conveying module 3331, a third clamping drive 3332, and second clamping members 3333. The conveying module 3331 consists of two linear modules, one arranged along the Y-axis and the other along the Z-axis. The third clamping drive 3332 is connected to the conveying module 3331 to move along the Y-axis and Z-axis. The third clamping drive 3332 is a gripper cylinder with two output ends that can move in opposite directions or in opposite directions along the Y-axis. There are two second clamping members 3333, which are respectively connected to different output ends of the third clamping drive 3332. The two second clamping members 3333 can cooperate to clamp a workpiece unit under the drive of the third clamping drive 3332, and move it to the second tray 350 at the third position under the drive of the conveying module 3331.

[0096] Furthermore, referring to Figure 16 and Figure 23 As shown, the second receiving device 340 includes a tray unloading line 341, a third lifting platform 342, and a fourth lifting platform 343. The tray unloading line 341 is a roller conveyor arranged along the X-axis direction, located below the second transfer platform 313. The input end of the tray unloading line 341 is located directly below the third position. The third lifting platform 342 is located at the input end of the tray unloading line 341 and can rise to receive the second tray 350 released by the fixing mechanism 314, and lower it onto the tray unloading line 341. The fourth lifting platform 343 is located at the output end of the tray unloading line 341 and can lift the second tray 350 flowing to the output end of the tray unloading line 341 and rise to the fourth position for removal by operators or robots. The third lifting platform 342 and the fourth lifting platform 343 are both conventional lifting machine structures, which will not be described in detail here.

[0097] The fully automatic cleaning system of the present invention operates as follows: The first tray-dispensing device 210 lowers the first tray 250 containing the workpieces 400 to be cleaned; the first tray transfer line 221 receives the first tray 250 and transfers it to a first position; the first transfer platform 222 lifts the first tray 250, connecting one of its storage compartments 251 with the input end of the first workpiece conveyor line 231; the first side-pushing mechanism 232 pushes the entire row of workpieces 400 in the storage compartment 251 into the first workpiece conveyor line 231; then, the first transfer platform 222 slightly moves the first tray 250, connecting the other storage compartment 251 with the input end of the first workpiece conveyor line 231, so that the first side-pushing mechanism 232 performs another side-pushing operation until the first tray 250 is empty, at which point the first transfer platform 222 transfers the first tray 250 to a second position; the first lifting... The lowering platform 242 rises to support the first tray 250 at the second position, the first transfer platform 222 moves away from the second position, and the first lifting platform 242 descends to place the first tray 250 on the second tray transfer line 241. The second tray transfer line 241 drives the first tray 250 to the roller line 245, where the first tray 250 flows from the high end to the low end of the roller line 245 under gravity. Then, the second lifting platform 246 rises to the low end of the roller line 245, and the roller line 245 releases the first tray 250 at the low end, allowing the first tray 250 to be supported by the second lifting platform 246. Whenever the second lifting platform 246 receives a first tray 250, it descends by the height of one first tray 250, allowing the first trays 250 to gradually stack on the second lifting platform 246 and be placed into the receiving cart 247 under the descent of the second lifting platform 246.

[0098] When the workpiece 400 is pushed into the first workpiece conveyor line 231, the first workpiece conveyor line 231 carries the workpiece 400 into the cleaning conveyor line 110, and the cleaning conveyor line 110 carries the workpiece 400 through the cleaning device 120 for sandblasting cleaning; during this process, the pressing mechanism 140 is in a pressing state that matches the height of the workpiece 400, so that the workpiece 400 entering the cleaning area is limited in the Z-axis direction, thereby improving the cleaning quality.

[0099] After the workpiece 400 is cleaned, it flows from the output end of the cleaning conveyor line 110 into the second workpiece conveyor line 321. The workpieces 400 on the second workpiece conveyor line 321 pass through the blowing mechanism 325 and the intercepting mechanism 322 in sequence before flowing into the third workpiece conveyor line 323. When the third workpiece conveyor line 323 receives a preset number of workpieces 400, the intercepting mechanism 322 intercepts the workpieces 400 on the second workpiece conveyor line 321. At the same time, the second side-pushing mechanism 331 clamps the workpieces 400 on the third workpiece conveyor line 323 and pushes them to the transfer table. 332, the conveying mechanism 333 moves the workpiece 400 on the transfer table 332 to the second tray 350 at the third position, repeating the above action until the second tray 350 is full; the third lifting platform 342 lowers the full second tray 350 to the tray unloading line 341, the tray unloading line 341 moves the second tray 350 to the output end, the fourth lifting platform 343 lifts the second tray 350 to the fourth position for the operator or robot to remove, at the same time, the second tray dispensing device 310 continues to dispense the empty second tray 350 to the third position.
