Description

Technical Field

[0001] This utility model relates to the field of 3C component processing technology, and in particular to a fully automatic sandblasting machine. Background Technology

[0002] With the rapid development of the 3C industry, components for products such as smartphones, tablets, and smart wearable devices are becoming increasingly miniaturized, precise, and complex. This places increasingly stringent requirements on the surface finish, flatness, and consistency of these components. 3C components are mostly made of materials such as aluminum alloys, stainless steel, glass, and engineering plastics, and often feature complex curved surfaces, tiny holes, and thin-walled structures. Traditional manual polishing is inefficient and prone to causing deformation or scratches, while mechanical grinding is ill-suited for the comprehensive polishing of complex structures. Currently, fully automatic sandblasting machines are mainly used to impact and grind the surface of parts by high-speed jetting of abrasives (such as quartz sand and alumina sand). This can achieve non-contact polishing, which can avoid damage to parts caused by mechanical force and efficiently process complex surface structures. It has gradually become one of the core equipment for polishing 3C parts.

[0003] However, in the aforementioned prior art, the workpiece cannot be rotated and polished, making it difficult to accurately cover all areas to be polished.

The two sets of feeding assemblies are respectively located on one side of the frame 102.

[0037] In this embodiment, the six-axis robot 111 controls the double-sided adsorption clamp 112 to pick up the workpieces from the feeding assembly and place them neatly onto the corresponding rotating parts. The first drive motor 104 is started, causing the first sprocket 103 to rotate, which in turn drives the chain 105 to move the rotating parts toward the inner wall of the sandblasting chamber 101. At the same time, the second drive motor 109 is started, causing the rolling wheel 108 to rotate the horn belt 107. With the cooperation of the first I-ring 110, the horn belt 107 is driven to contact the rotating parts, thereby realizing the rotation of the rotating parts. Then, the sandblasting assembly is used for processing. The counterweight assembly is used to adjust the tension of the chain 105.

[0044] In this embodiment, the sand outlet chamber 118 and the suction-type sandblasting gun 117 are used for grinding the surface of the workpiece. Abrasive particles of 300 to 500 mesh fall into the receiving chamber 122, are then concentrated and conveyed by the double-spiral reverse feeder 123 to the spiral feeder 124, move through the spiral feeder 124 to the spiral elevator 125, and are then transported to the sand outlet chamber 118 via the connecting pipe 126, forming a recycling of the abrasive particles; this is the first sand return method. The automatic feeding tank 129 adds new abrasive particles periodically to ensure sufficient internal abrasive. During this process, the suction-type sandblasting gun 117 utilizes a negative... The abrasive-gas mixture is drawn in by pressure and transported to the four-tube cyclone separator 120 via the dust extraction pipe 119. The abrasive and gas are separated by cyclone separation. The abrasive then enters the screw feeder 124 from the bottom, while the separated gas is treated by the dust collector 121 and discharged. This is the second method of sand return. Using these two methods improves the efficiency of sand return. The heater 128 heats the abrasive to prevent it from becoming damp. The vibrator 127 is used to improve the flowability of the abrasive. Since the abrasive is relatively fine, the four-tube cyclone separator 120 is used here to improve the efficiency of abrasive separation.

The multiple secondary gear shafts 146 are rotatably connected to the T-shaped frame 142 and are located on one side of the T-shaped frame 142. The multiple flexible clamps 147 are connected to the corresponding secondary gear shafts 146 and are located on one side of the secondary gear shafts 146. The rotating toothed belt 144 is sequentially sleeved on the outer side wall of the main gear shaft 145 and the multiple secondary gear shafts 146.

[0051] In this embodiment, the third lateral movement module 139 is used to drive the connecting frame 140 to move laterally, while the vertical movement module 141 is used to adjust the height of the connecting frame 140. With the cooperation of the third lateral movement module 139 and the vertical movement module 141, the flexible clamp 147 moves closer to the workpiece. Then, the controller controls the flexible clamp 147 to clamp the workpiece, and the third drive motor 143 is started to drive the main gear shaft 145 to rotate. Since the rotating toothed belt 144 is sequentially sleeved on the main gear shaft 145 and multiple secondary gear shafts 146, the flexible clamp 147 will clamp the workpiece and flip it. Then, under the linkage of the third lateral movement module 139 and the vertical movement module 141, it is placed back onto the quick-release piece 134.

[0052] Further, the mounting frame 148 is disposed on one side of the frame 102, the Delta robot 149 is connected to the mounting frame 148 and located on the inner top wall of the mounting frame 148, the adjustable clamp 150 is detachably connected to the Delta robot 149 and located at the output end of the Delta robot 149, the loading rack 151 is disposed on the inner side wall of the mounting frame 148, the symmetrical support 152 is fixedly connected to the loading rack 151 and located on the inner side wall of the loading rack 151, a plurality of pulleys 153 are rotatably connected to the symmetrical support 152 and are respectively located on the inner side wall of the symmetrical support 152, the conveyor belt 154 is sleeved on the outer side wall of the plurality of pulleys 153, the first cylinder 155 is disposed between the symmetrical supports 152, and the support frame 156 is connected to the...

The lifting frame 161 is fixedly connected to the third cylinder 160 and located at the output end of the third cylinder 160, and the lifting frame 161 is slidably engaged with the symmetrical support 152.

[0053] In this embodiment, during use, the first cylinder 155 drives the support frame 156 to move upward and contact the material tray on the inner wall of the fixed frame 157. Then, the second cylinder 158 drives the limiting frame 159 to remove the restriction on the material tray, allowing it to move up and down within the fixed frame 157. Afterward, the first cylinder 155 retracts, causing the material tray to contact the conveyor belt 154. The limiting frame 159 resets, allowing the operator to place a new material tray. Simultaneously, the pulley 153 rotates, driving the material tray to move above the lifting frame 161. The third cylinder 160 is then activated, causing it to move the material tray upward, facilitating the Delta robot 149 to grasp it using the adjustable gripper 150. The adjustable gripper 150 can be adjusted for gap using cylinders, improving ease of use.

[0054] The Delta robots 149 are arranged in two sets within the mounting frame 148. They can grip the workpieces at the loading station and collect the completed workpieces at the unloading station.

[0055] Furthermore, the unloading rack 163 is disposed on one side of the frame 102, the slide rail 164 is fixedly connected to the unloading rack 163 and located above the unloading rack 163, the feeding rack 165 is slidably connected to the slide rail 164 and located above the slide rail 164, the fourth lateral movement module 166 is disposed above the unloading rack 163, and the output end of the fourth lateral movement module 166 is fixedly connected to the feeding rack 165.

[0056] In this embodiment, the six-axis robot 111 picks up the empty material tray from the loading station and places it onto the first lateral movement module 137. The first lateral movement module 137 is used to move the material tray to the left to form station C, while the second lateral movement module 138 forms station D on the left. The two sets of material trays are not on the same plane. When station C finishes receiving the material, it will move quickly to the right, while the material tray on station D will move quickly to the left, forming a Z-shaped intersection with station A, which improves the efficiency and quality of unloading. The fourth lateral movement module 166 drives the unloading rack 165 to slide on the slide rail 164, which facilitates the collection of the finished workpieces.

[0057] Furthermore, the first side frame 167 is fixedly connected to the frame 102 and located above the frame 102; the first nozzle 168 is detachably connected to the first side frame 167 and located on the inner top wall of the first side frame 167; the spring column 169 is detachably connected to the frame 102 and located above the frame 102; the three sets of clamping components are respectively connected to the frame 102; and the two sets of detection components are respectively connected to the frame 102.

[0058] In this embodiment, the spring column 169 straightens the workpiece during the movement of the chain 105, while the high-pressure gas ejected from the first nozzle 168 provides downward pressure to the workpiece during the straightening process, preventing it from falling off. The three sets of clamping components are used to adjust the gap between the workpieces. The first set of clamping components is placed at the loading station to clamp the workpiece at the loading station, ensuring the placement accuracy of the workpiece. The second set of clamping components is placed at the flipping station to prevent deviation after flipping. The third set of clamping components is placed at the unloading station to prevent the workpiece from tilting during grinding, facilitating the subsequent clamping by the adjustable fixture 171. The two sets of detection components are used to detect whether the workpiece is placed in reverse. One set of detection components is placed at the loading station to detect the orientation of the placed workpiece; the other set of detection components is placed at the flipping station to detect the flipped workpiece.

[0059] Furthermore, the U-shaped frame 170 is fixedly connected to the frame 102 and located above the frame 102; the symmetrical clamping fixture 171 is connected to the U-shaped frame 170 and located on the inner top wall of the U-shaped frame 170; the receiving bin 172 is fixedly connected to the frame 102 and located on one side of the frame 102; the sensor 173 is fixedly connected to the frame 102 and located above the frame 102; the second side frame 174 is detachably connected to the frame 102 and located above the frame 102; and the second nozzle 175 is detachably connected to the second side frame 174 and located below the second side frame 174.

[0060] In this embodiment, at the loading station: the symmetrical clamping fixture 171 can adjust the gap between the workpieces to ensure placement accuracy; at the flipping station: the symmetrical clamping fixture 171 can clamp the workpieces to prevent deviations after flipping; at the unloading station: to prevent tilting of the workpieces during grinding, facilitating subsequent gripping by the adjustable fixture 171; the sensor 173 is used to detect whether the workpieces are placed backwards. When a problem occurs, the second nozzle 175 will eject high-pressure gas to apply pressure to the bottom of the workpiece, allowing it to detach from the quick-release piece 134 and fall into the receiving bin 172. For easy collection and processing by staff; once the first drive motor 104 and the second drive motor 109 enter a stable operating state, the entire processing system maintains a continuous operation mode without stopping. The six-axis robot 111 initiates coordinated actions based on a preset precise trajectory program: first, the double-sided adsorption gripper 112 mounted at its end smoothly picks up the workpiece to be processed, and accurately transfers the workpiece to the rotating part with a smooth multi-axis linkage posture; at the same time, the symmetrical clamping gripper 171 responds synchronously, using a symmetrical clamping structure to quickly fit the surface of the rotating part, adjust the gap of the workpiece, and finally strictly control the error within the preset allowable range to ensure the accuracy requirements.

[0061] Fully automatic sandblasting machine overall processing flow: When using this device, the first drive motor 104 and the second drive motor 109 start synchronously. At the same time, the second drive motor 109 on the reverse side also starts synchronously. The first sprocket 103 drives the chain 105 and the rotating part to rotate. The second drive motor 109 drives the horn belt 107 to rotate. When feeding: the first cylinder 155 drives the support frame 156 to move upward and contact the material tray on the inner wall of the fixed frame 157. Then, the second cylinder 158 drives the limiting frame 159 to remove the restriction on the material tray, so that it can move up and down within the fixed frame 157. After that, the first cylinder 155 retracts, causing the material tray to contact the conveyor belt 154.Simultaneously, the pulley 153 rotates, driving the material tray to move above the lifting frame 161. The third cylinder 160 is activated, causing it to move the material tray upwards, facilitating gripping by the Delta robot 149 using the adjustable clamp 150. The workpiece is then inserted into the quick-release piece 134. The symmetrical clamping fixture 171 adjusts the gap between the workpiece and the workpiece to ensure placement accuracy. The spring column 169 aligns the workpiece, while the high-pressure gas ejected from the first nozzle 168 provides downward pressure during alignment, preventing it from falling off. The sensor 173 detects the orientation of the placed workpiece, and the second nozzle 175 will activate if a problem occurs. High-pressure gas is ejected to apply pressure to the bottom of the workpiece, allowing it to detach from the quick-release component 134 and fall into the receiving hopper 172. The workpiece is now located inside the sandblasting chamber 101, where it is polished using the suction-type sandblasting gun 117. During this process, the horn belt 107 contacts the outer wall of the second I-ring 133, which rotates under the support of the rolling bearing 131, ensuring uniform contact between the workpiece and the abrasive. When the workstation is flipped, the third lateral movement module 139 and the vertical movement module 141 work together to bring the flexible clamp 147 closer to the workpiece. The controller then controls the flexible clamp 147 to grip the workpiece, initiating the process. The third drive motor 143 is activated, causing the main gear shaft 145 to rotate. Since the rotating toothed belt 144 is sequentially mounted on the main gear shaft 145 and multiple secondary gear shafts 146, the flexible clamp 147 clamps the workpiece and flips it. Then, under the linkage of the third horizontal moving module 139 and the vertical moving module 141, it is placed back onto the quick-release piece 134. The symmetrical clamping clamp 171 then clamps the workpiece to prevent deviation after flipping. The sensor 173 detects this in real time; incorrectly placed workpieces are blown off by the second nozzle 175. As the chain 105 moves, the workpiece re-enters the sandblasting chamber 101, and the workpiece is also moved by the horn belt. With the assistance of 107, the workpiece rotates. During unloading, the symmetrical clamping fixture 171 clamps the workpiece again, facilitating the adjustable fixture 150, controlled by the Delta robot end effector, to pick it up and place it into the empty tray. The empty tray needs to be picked up by the six-axis robot 111 from the loading rack 151, rotated, and shaken to prevent any un-clamped workpieces from remaining on it. The empty tray is then placed at the unloading station. After unloading, the six-axis robot 111 picks up the tray again and places it into the unloading rack 165. The fourth lateral movement module 166 drives the unloading rack 165 to slide on the slide rail 164, facilitating the collection of the finished workpieces, thus completing the entire polishing process.
