Description

Technical Field

[0001] This invention relates to the field of automated feeding technology, and in particular to a feeding and unloading device with buffered feeding capability. Background Technology

[0002] In the electronics industry, component feeding is the process of transporting a large number of tiny and precision electronic components to automated production lines for subsequent mounting, insertion, or testing operations. It is an essential support system for achieving automated, efficient, high-precision, and high-quality production.

[0003] In the existing workpiece feeding process, pallets containing workpieces are manually placed onto a conveyor, which then transports the workpieces to a robot. The robot then picks up the workpieces and places them into an inspection device for testing. After inspection, the conveyor sends out an empty pallet, which is then replaced with a pallet containing workpieces for the next feeding cycle. However, this process only allows one pallet to be placed at a time, requiring frequent feeding by workers, resulting in high labor intensity. Furthermore, the robot and inspection equipment are not running during the feeding process, causing waiting time and impacting work efficiency. Summary of the Invention

The second cylinder 1319 has a push block 1320 connected to its movable end. Indicator lights 1321 are evenly spaced from top to bottom on the upper right side of the bellows cover 10. The number of indicator lights 1321 is the same as that of the storage rack 131, and the indicator lights 1321 and the storage rack 131 correspond one-to-one. The multi-stage cylinder 1310, the loading conveyor 1312, the first electric guide rail 1313, the first cylinder 1314, the second photoelectric sensor 1316, the unloading conveyor 1317, the second electric guide rail 1318, the second cylinder 1319, and the indicator lights 1321 are all electrically connected to the controller 12.

[0037] refer to Figure 11 and Figure 12It also includes a discharge mechanism, which includes a discharge conveyor 142, a third photoelectric sensor 143, and a baffle 144. The discharge conveyor 142 is bolted to the left rear side of the bellows cover 10. The third photoelectric sensor 143 is bolted to the top left front side and right rear side of the discharge conveyor 142. The discharge conveyor 142 and the third photoelectric sensor 143 are electrically connected to the controller 12. The baffle 144 is bolted to the top right rear side of the discharge conveyor 142.

[0038] refer to Figure 1 and Figure 13 It also includes a protective mechanism, which includes a grating sensor 151 and a cover plate 152. The grating sensor 151 is bolted to both the front and rear sides of the right side of the bellows cover 10. The safety grating emitted by the grating sensor 151 can cover the feed port on the right side of the bellows cover 10. The grating sensor 151 is electrically connected to the controller 12. The right side of the bellows cover 10 is provided with a cover plate 152.

[0039] Workers place a tray containing workpieces into the storage rack 131 through the feed inlet on the right side of the accordion cover 10. Support wheels 132 support the trays. Each tray contains multiple workpieces, which are evenly spaced and neatly arranged. The first photoelectric sensor 133 on the right first detects the tray containing workpieces and sends a signal to the controller 12. Upon receiving the signal, the controller 12 controls the extension of the movable end of the telescopic cylinder 134 on the left, causing the stop block 135 on the left to move forward. The stop block 135 on the left blocks the tray containing workpieces, preventing it from moving too far to the left. Subsequently, the first photoelectric sensor 133 on the left will detect the tray containing workpieces again. Sensor 133 sends a signal to controller 12. After receiving the signal, controller 12 controls the movable end of the right-side telescopic cylinder 134 to extend, causing the right-side stop block 135 to move forward. The two stop blocks 135 can block the pallet containing the workpiece, preventing it from slipping out of the storage rack 131. Initially, the movable end of the multi-stage cylinder 1310 is extended, and the feeding conveyor 11 and the first-layer storage rack 131 (the number of layers in the storage rack 131 increases from bottom to top) are flush with the loading conveyor 1312. Controlling the movable end of the first cylinder 1314 to extend causes the pull block 1315 to move downward. The pull block 1315 hooks the pallet containing the workpiece in the first-layer storage rack 131, and then controls the first electric guide rail 131. 3. The first cylinder 1314 moves to the left, which in turn moves the pull block 1315 to the left. The pull block 1315 pulls the pallet containing the workpiece onto the loading conveyor 1312. Then, the movable end of the first cylinder 1314 is shortened, causing the pull block 1315 to move upward, so that the pull block 1315 no longer hooks onto the pallet containing the workpiece. The loading conveyor 1312 is then controlled to convey the pallet containing the workpiece to the left, transporting it onto the feeding conveyor 11. The second photoelectric sensor 1316 on the right first detects the pallet containing the workpiece and sends a signal to the controller 12. After receiving the signal, the controller 12 controls the feeding conveyor 11 to operate, and the feeding conveyor 11 also conveys the pallet containing the workpiece to the left. The workpiece tray is brought close to the R1 robot 9. Subsequently, the second photoelectric sensor 1316 on the left side also detects the workpiece tray and sends a signal to the controller 12. Upon receiving the signal, the controller 12 shuts down both the loading conveyor 11 and the filling conveyor 1312. At this time, the R1 robot 9 grabs the workpiece from the loading conveyor 11 and places it into the FCT test fixture 4. The FCT test fixture 4 performs an FCT test. If the FCT test fails, the R1 robot 9 places the failed workpiece onto the unloading conveyor 142. The third photoelectric sensor 143 on the left side detects the workpiece and sends a signal to the controller 12.After receiving the signal, the controller 12 controls the discharge conveyor 142 to operate. The discharge conveyor 142 transports the defective workpiece to the right. Subsequently, the third photoelectric sensor 143 on the right side also detects the defective workpiece and sends a signal to the controller 12. After receiving the signal, the controller 12 controls the discharge conveyor 142 to close. The baffle 144 can block the defective workpiece to prevent it from falling off the discharge conveyor 142. If the FCT test is qualified, the R1 robot 9 removes the workpiece from the FCT test fixture 4 and places it into the placement block 7. The electric slide rail 6 is controlled to move the placement block 7 forward, and the placement block 7 moves the workpiece forward. The workpiece will pass the CCD camera 8. Camera 8 can capture images of the workpiece and perform CCD testing. If the CCD test fails, robot R1 9 will place the defective workpiece onto the discharge conveyor 142 for easy removal by staff. If the CCD test passes, the qualified workpiece is conveyed out via electric slide rail 6. During the testing process, staff control the extension of the movable end of multi-stage cylinder 1310, causing lifting plate 139 to move upward. Lifting plate 139 then moves loading conveyor 1312 and unloading conveyor 1317 upward, aligning loading conveyor 1312 with the second-layer storage rack 131 and pulling the pallet containing the workpiece from the second-layer storage rack 131 onto loading conveyor 1312. Before each time a pallet containing workpieces in storage rack 131 is pulled onto the loading conveyor 1312, the telescopic cylinder 134 moves the stop block 135 backward, so that the stop block 135 no longer blocks the pallet containing workpieces. Then, the movable end of the multi-stage cylinder 1310 is shortened, causing the unloading conveyor 1317 to move downward, making the unloading conveyor 1317 level with the loading conveyor 11. After all the workpieces on the loading conveyor 11 have been inspected, the loading conveyor 11 reverses and transports the empty pallet to the unloading conveyor 1317. At this time, the operator shortens the movable end of the multi-stage cylinder 1310, causing the unloading conveyor 1317 to move downward, making the unloading conveyor 1317 level with the first-layer storage rack 131. The second electric guide rail 1318 drives the second cylinder 1319 and push block 1320 to move to the left, moving push block 1320 to the upper left of the empty tray. Then, the movable end of the second cylinder 1319 is extended, driving push block 1320 downward, moving push block 1320 to the left side of the empty tray. Then, the second electric guide rail 1318 drives the second cylinder 1319 and push block 1320 to the right, pushing push block 1320 to the right and pushing the empty tray into the storage rack 131 on the first layer. Indicator lights 1321 correspond one-to-one with storage racks 131. When a tray containing a workpiece is placed in storage rack 131, its corresponding indicator light 1321 lights up; when an empty tray is placed in storage rack 131, its corresponding indicator light 1321 turns off.Specifically, the above actions can be performed using weight sensors, photoelectric sensors, etc. Workers use indicator lights 1321 to determine if there are workpieces in the storage rack 131, then control the extension of the movable end of the multi-stage cylinder 1310, driving the loading conveyor 1312 upwards until it is aligned with the feeding conveyor 11. The loading conveyor 1312 then transports the pallet containing the workpieces to the feeding conveyor 11 for further inspection. This cycle repeats automatically, reducing manual intervention and thus lessening the workload of workers. Furthermore, rapid replenishment after unloading reduces the waiting time of the R1 robot 9, thereby improving work efficiency. The safety light emitted by the grating sensor 151 can cover the feed inlet on the right side of the bellows cover 10, and the cover plate 152 can cover the right side of the bellows cover 10. The feed inlet is sealed to prevent dust from entering the bellows-shaped protective cover 10. When it is necessary to replace the pallet in the storage rack 131, the cover plate 152 is opened, and then the empty pallet in the storage rack 131 is taken out and replaced with a pallet containing workpieces. The pallet can be replaced at any time without affecting the overall work rhythm. During the pallet replacement, the worker may come into contact with the safety light grid emitted by the grating sensor 151. At this time, the multi-stage cylinder 1310, the loading conveyor 1312, the first electric guide rail 1313, the unloading conveyor 1317, and the second electric guide rail 1318 all stop operating to prevent worker injury. When other objects come into contact with the safety light grid emitted by the grating sensor 151, the multi-stage cylinder 1310, the loading conveyor 1312, the first electric guide rail 1313, the unloading conveyor 1317, and the second electric guide rail 1318 will also stop operating.

[0040] refer to Figure 14 and Figure 15 It also includes a storage mechanism, which includes a storage plate 161, a telescopic support rod 162 and a limiting component. The storage plate 161 is hinged to the middle right side of the bellows cover 10. The telescopic support rod 162 is hinged to both the front and rear sides of the middle right side of the bellows cover 10. The right end of the telescopic support rod 162 is hinged to the bottom of the storage plate 161. The limiting component is used to limit the workpiece on the storage plate 161.

[0041] refer to Figure 14 and Figure 15 The limiting assembly includes a limiting plate 163, a fixing plate 164, and a limiting block 165. The top front and rear sides of the storage plate 161 are both connected to the limiting plate 163 by bolts. The right middle part of the bellows cover 10 is connected to the fixing plate 164 by bolts. The fixing plate 164 is located above the storage plate 161. The right middle part of the fixing plate 164 is connected to the limiting block 165 by bolts.

[0042] Workers can place the pallet containing the workpieces onto the storage plate 161 for storage, making it convenient for later retrieval. The limiting plate 163 and the limiting block 165 can limit the pallet containing the workpieces to prevent displacement. The telescopic support rod 162 has a damping function, which can support the storage plate 161 and keep it in a horizontal state. When the workpieces do not need to be tested, the storage plate 161 can be rotated downwards to retract it, saving space. At the same time, the telescopic support rod 162 can be shortened.

[0043] refer to Figure 16 It also includes a pressing mechanism, which includes a rotary cylinder 171 and a pressure block 172. Two rotary cylinders 171 are bolted to the top of the FCT test fixture 4. After the workpiece is placed in the FCT test fixture 4, the workpiece will be located between the two rotary cylinders 171. The rotary cylinders 171 are electrically connected to the controller 12. A pressure block 172 is connected to the movable end of each rotary cylinder 171.

[0044] The operator controls the movable end of the rotary cylinder 171 to extend and rotate, causing the pressure block 172 to move upward and rotate, opening the pressure block 172 to place the workpiece. After the R1 robot 9 places the workpiece into the FCT test fixture 4, it controls the movable end of the rotary cylinder 171 to shorten and rotate, causing the pressure block 172 to move downward and rotate, rotating the pressure block 172 above the workpiece and pressing it down to prevent the workpiece from shaking and improve the accuracy of the test.
