[0029] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0030] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 8 As shown in the figure, an automatic bearing feeding device provided by this utility model includes a bearing outer ring placement platform 2. A bearing extraction mechanism 3 for moving the bearing outer ring is fixedly installed on the upper part of the bearing outer ring placement platform 2. A positioning mechanism 4 for fixing the bearing outer ring during the bearing extraction process is provided on one side of the bearing extraction mechanism 3. The positioning mechanism 4 is fixed on the bearing outer ring placement platform 2. The positioning mechanism 4 includes a cylinder seat 401. A drive cylinder 402 is fixedly installed on the upper part of the cylinder seat 401. A pin 407 is fixedly connected to the output end of the drive cylinder 402 through the cylinder seat 401. A first sensor 403 for detecting whether the pin 407 is in place is fixedly installed on one side of the cylinder seat 401. The cylinder seat 401 is fixed on the bearing outer ring placement platform 2.

[0032] In the aforementioned automatic bearing feeding equipment, the operator sequentially inserts the bearing outer rings into the bearing stop 202 on the bearing outer ring placement platform 2 to ensure that the feeding is complete. The drive cylinder 402 is in the initial position, the pin 407 is not extended, and the first sensor 403 does not detect the pin 407 being in place. After all initial signals are detected as normal, the automatic feeding process begins. When the drive cylinder 402 is activated, the pin 407 extends and inserts into the fixing hole or slot of the bearing outer ring to fix the position of the bearing outer ring. After the pin 407 is in place, the first sensor 403 detects in real time whether the pin 407 is fully inserted. If a signal is detected, the equipment's control system confirms that the bearing outer ring is successfully fixed. If no signal is detected, the control system issues an alarm and suspends operation.

[0033] The control system drives the bearing extraction mechanism 3 to perform the extraction action. The extraction head or clamp contacts the outer ring of the bearing and clamps the outer ring. The extraction mechanism smoothly moves the outer ring of the bearing from the placement table to the target position. During the extraction process, the position of the outer ring of the bearing and the status of the clamp are monitored by sensors to ensure that the extraction action is smooth and there is no risk of slippage or falling. During the extraction process, the first sensor 403 monitors the position of the outer ring of the bearing and the status of the clamp to ensure that the extraction action is smooth and there is no risk of slippage or falling.

[0034] In this embodiment, a pin seat 406 is fixedly connected to the upper part of the cylinder seat 401, and a pin 407 is slidably installed inside the pin seat 406. A sensing pin 405 is fixedly installed on one side of the lower part of the pin 407. The first sensor 403 monitors the position of the sensing pin 405 in real time. A first sensor bracket 404 is fixedly installed on one side of the cylinder seat 401, and the first sensor 403 is fixedly installed on the first sensor bracket 404.

[0035] The pin 407 is initially retracted under the control of the cylinder. At this time, the first sensor 403 is working, but no signal is detected from the sensing pin 405. After receiving the control signal, the cylinder pushes the pin 407 downward along the internal sliding trajectory of the pin seat 406. The pin 407 slides stably inside the pin seat 406 until the sensing pin 405 moves to the detection area of ​​the first sensor 403. When the pin 407 moves to the target position, the sensing pin 405 aligns with the first sensor 403. The first sensor 403 detects the signal and sends feedback to the control system. The control system confirms whether the pin 407 has reached the designated position through the signal from the first sensor 403. If the first sensor 403 does not detect the signal, the system pauses the current action and alarms to indicate abnormal operation. After the pin 407 is in place, it ensures that it accurately positions or fixes the outer ring of the bearing.

[0036] Then the control system sends a reset signal, and the cylinder drives the pin 407 to slide back to its initial position along the pin seat 406. After the pin is reset, the sensing pin 405 leaves the detection area of ​​the first sensor 403, and the system confirms that the pin 407 has completed the reset.

[0037] In this embodiment, a barcode scanner 5 for scanning and recording materials during material feeding is fixedly installed on one side of the bearing outer ring placement platform 2.

[0038] The operator places the bearing outer ring or other materials on the bearing outer ring placement platform 2, ensuring that the barcode on the material faces the scanning area of ​​the barcode scanner 5. The control system automatically detects the material placement signal, or the scanning action is initiated by the built-in trigger device of the barcode scanner 5. The barcode scanner 5 quickly scans the barcode and uploads the information to the control system. The scanned material barcode information is displayed on the system interface and checked against the archived information in the database. If the barcode information is valid, the system confirms that the material has been recorded; if the information is invalid, the system prompts to rescan or check the barcode. The correspondence between barcode information and materials is stored in the system, generating a unique tracking identifier, which facilitates subsequent production, assembly, and warehousing management. The barcode information guides the material into subsequent operation processes, such as automatic feeding or sorting. If subsequent stages require querying the material source or batch information, it can be quickly located in the system through the barcode.

[0039] In this embodiment, the bearing outer ring placement platform 2 includes a base 212 for placement on the ground. A support 211 and several guide supports 209 are fixedly installed on the upper part of the base 212. Guide bars 207 are fixedly installed on the guide supports 209 through guide fixing blocks 208. A rotary bearing 213 is fixedly installed on the upper part of the support 211. A placement base plate 203 is fixedly installed on the upper part of the rotating part of the rotary bearing 213. Several bearing limiting members are fixedly installed on the lower part of the placement base plate 203. The bearing limiting members include a stop bar 202 and a bearing upper cover 201. The stop bar 202 of the bearing limiting members is provided with There are three bearings, and one bearing cover 201. Several guide blocks 206 are fixedly installed on the lower part of the base plate 203. The guide blocks 206 rotate along the guide strip 207. A base sensor 204 for sensing the guide blocks 206 is fixedly installed on the sensor base bracket 205 fixed on one side of the base 212. A motor 210 is also fixedly installed on the upper part of the base 212. The output end of the motor 210 is fixedly connected to the rotating part of the rotary bearing 213. The baffle 202 is fixedly connected to the upper part of the base plate 203. The bearing cover 201 is fixedly connected to the upper part of the baffle 202.

[0040] The bearing outer ring placement platform 2 is driven by a motor 210 to rotate the bearing 213, which in turn rotates the placement base plate 203, enabling bearing loading at different workstations. During operation, the workpiece presence sensor 105 detects whether there is material in the current stop bar 202. If so, the positioning mechanism 4 locks the placement base plate 203, and the bearing extraction mechanism 3 removes the bearing outer ring and sends it to the next process. Subsequently, the motor 210 starts, rotating the placement base plate 203 to the next workstation. The guide block 206 slides along the guide strip 207 until the base sensor 204 detects that the bearing is in position, at which point the motor 210 stops, and the positioning mechanism 4 locks again to complete a new round of loading. After all workstations have been loaded with bearings, the system resets, ready for the next cycle. The design is simple and efficient, ensuring accurate positioning and continuous operation, and is suitable for mass production needs.

[0041] In this embodiment, the bearing extraction mechanism 3 includes a fixed base 305, which is fixed on the upper part of the bearing outer ring placement platform 2. A linear slide rail 304 is fixedly installed on the lower part of the transverse moving cylinder 303 fixedly mounted on the fixed base 305. A vertical moving cylinder 310 is fixedly mounted on the transverse moving cylinder 303 through a connecting block 309. The output end of the vertical moving cylinder 310 is fixedly connected to a workpiece support 3012. A workpiece initial sensor 302 fixedly mounted on one side of the fixed base 305 performs the initial state detection action of the cylinder. A sensing block 311 is fixedly mounted on one side of the workpiece initial sensor 302. The sensing block 311 performs the workpiece sensing action through a sensor 307. A sensor 307 is fixedly mounted on a sensing bracket 308 fixedly mounted on one side of the fixed base 305. A cable chain 306 for placing cables and air pipes is also fixedly mounted on one side of the sensing bracket 308. A final working sensor 313 and a camera mechanism 301 fixedly mounted on one side of the fixed base 305 perform the final detection action of the presence or absence of the workpiece.

[0042] The bearing extraction mechanism 3, through the cooperation of the up-and-down moving cylinder 310 and the lateral moving cylinder 303, achieves precise extraction and movement of the outer ring of the bearing. At the start of the operation, the initial workpiece sensor 302 detects whether there is a bearing ready for extraction. If detected, the lateral moving cylinder 303 drives the up-and-down moving cylinder 310 to the bearing position. The up-and-down moving cylinder 310 descends, and the workpiece support 3012 contacts the bearing and begins to rise, completing the extraction action. Subsequently, the lateral moving cylinder 303 drives the workpiece support 3012 to move the bearing to the designated position. At the end of the operation, the sensor 313 detects whether the bearing is in place. After confirmation, the lateral movement stops, the current cycle is completed, and the operation proceeds to the next station.

[0043] In this embodiment, a protective cover 1 is fixedly installed on the upper part of the bearing outer ring. The protective cover 1 includes a frame 102, and a protective cover 104 is mounted on the frame 102 via a nitrogen spring 103. A handle 108 is fixedly connected to the upper part of the protective cover 104. An upper limit 101 and a lower limit 107 for limiting the rotation of the protective cover 104 are fixedly connected to the upper and lower parts of the frame 102. A detection sensor 106 fixed on one side of the frame 102 detects the protective cover 104 when it is closed. A flat plate 109 fixed to the bottom of the frame 102 is used to temporarily place the workpiece, and a workpiece presence / absence sensor 105 fixed to one side of the bottom of the frame 102 is used to detect the presence or absence of the workpiece in real time.

[0044] The equipment protective cover 1, consisting of a frame 102 and a protective cover 104, forms a protective structure to ensure safety and convenience during operation. The protective cover 104 is connected to the frame 102 via a nitrogen spring 103 and is equipped with a limit device to prevent excessive rotation. A handle 108 is provided on the top for easy opening and closing. When the protective cover 104 is closed, a detection sensor 106 monitors its position to ensure that the protective measures are effective before the equipment is put into operation. A flat plate 109 is provided at the bottom of the frame 102 for temporarily placing workpieces. A workpiece presence sensor 105 detects the presence of workpieces in real time, providing a condition judgment for equipment operation.
