Abstract
Description
Technical Field
[0001] This invention belongs to the field of rolling bearing processing technology and relates to an automatic stamping and typing production line. Background Technology
[0002] As a core component of mechanical transmission, rolling bearings require surface stamping to display key information such as model number, specifications, and production details. This process directly impacts product traceability and brand image. Currently, the industry commonly uses a manual operation of traditional stamping and typing machines, which has the following significant drawbacks: 1) Poor positioning accuracy: Relying on manual visual positioning of the bearings, the typing position has a large dispersion (the typing offset of the same model of product can reach ±2mm), which cannot guarantee the uniformity of the markings; 2) Poor processing consistency: Manual control of stamping pressure results in a fluctuation range of 0.1-0.3mm in the depth of the characters. Some markings are too shallow and easily wear out, while some are too deep and cause stress concentration on the bearing surface. 3) Low production efficiency: Each process requires 1-2 workers to complete the feeding, positioning, typing and stacking operations, with an average output of ≤300 pieces / hour per person. Moreover, the labor intensity is high and fatigue can further reduce efficiency. 4) High product damage rate: During manual stacking, bearings are directly stacked, and the surface scratches and edge damage caused by collisions are ≥5%, increasing the cost of subsequent screening. 5) Poor adaptability to model changes: When changing bearing models, the positioning reference needs to be readjusted, and manual adjustment takes ≥120 minutes, which cannot meet the needs of multi-variety small-batch production. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing an automatic stamping and typing production line for fully automatic directional conveying, precise stamping and typing, and material stacking of rolling bearings. This solves the technical problems of large typing position deviation, uneven typing depth, low production efficiency, easy collision damage to products, and difficulty in post-processing caused by the reliance on manual operation for stamping and typing of rolling bearings.

The identification sensor cooperates with the limiting cylinder to identify whether the printed side of the workpiece is facing upwards. The positioning component is used to intercept the workpiece at the end of the conveyor belt. Because the two end faces of the bearing are not the same, that is, the printed side and the non-printed side have identifiable structural differences, the identification sensor determines whether the currently upward-facing end face is the printed side by detecting the structural feature differences.

[0043] The working method of an automated stamping and typing production line includes: 1) Feeding: ① Start the feeding mechanism, the motor drives the conveyor belt. The transmission directions of adjacent conveyor belts are opposite. With the cooperation of the reversing track and the limiting track on the same side of the adjacent conveyor belts, the workpiece enters the next conveyor belt until it is moved to the output section of the last conveyor belt. ②When the first position sensor detects the workpiece, the first cylinder drives the limit rod to lift up to release the workpiece; Subsequently, the second cylinder drives the limit block to descend and press the workpiece, while the first cylinder drives the limit rod to descend to prevent subsequent workpieces from moving forward. The identification sensor identifies whether the workpiece at the second cylinder is facing up or not, and transmits the data on whether the workpiece is facing up or not to the PLC controller. After the identification is completed, the second cylinder drives the limit block to lift up to release the workpiece; ③ When the identified workpiece moves to the second position sensor under the action of the conveyor belt, the positioning cylinder drives the positioning block to descend and stop the workpiece at the end of the conveyor belt, waiting for the arrival of the conveying mechanism; At this time, the first cylinder drives the limit rod to lift up to release the next workpiece, and repeats the above action; 2) Conveying: After the feeding mechanism moves the workpiece to the end of the conveyor belt, the first feeding cylinder is activated to drive the clamping plate to move along the X-axis guide rail towards the positioning component. Then the second feeding cylinder drives the clamping plate to move along the Y-axis guide rail towards the positioning component. At the same time, the positioning cylinder drives the positioning block to rise, and the leftmost positioning clamp on the clamping plate clamps the workpiece at the end of the conveyor belt. The first feeding cylinder drives the clamping plate to move along the X-axis guide rail toward the flipping assembly, so that the workpiece enters the limiting groove of the flipping assembly; then, the second feeding cylinder drives the clamping plate to move away from the limiting groove along the Y-axis guide rail. Complete one cycle of operation for the conveying mechanism; 3) Stamping and typing ① When the workpiece enters the limit groove, the PLC controller uses the data from the recognition sensor to determine whether the printed side of the workpiece is facing up. If the non-printed side of the workpiece is facing up, the PLC controller controls the upper and lower jaws of the gripper cylinder to clamp and fix the workpiece, and controls the rotary motor to rotate 180° so that the printed side of the workpiece faces up. If the printed side of the workpiece is facing up, the gripper cylinder and the rotary motor do not operate. ② After that, the conveying mechanism completes the second action cycle. During this process, the first positioning fixture on the left side of the fixture plate moves the second workpiece from the end of the conveyor belt to the limiting groove of the flipping component, and the second positioning fixture on the left side moves the first workpiece from the limiting groove of the flipping component to the transition station. The transition station is located between the flipping component and the stamping and typing component. There is no movement at this station. ③ Next, the conveying mechanism completes the third action cycle. During this process, the first positioning fixture on the left side of the fixture plate moves the third workpiece from the end of the conveyor belt to the limiting groove of the flipping component, the second positioning fixture on the left side moves the second workpiece from the limiting groove of the flipping component to the transition station, and the third positioning fixture on the left side moves the first workpiece from the transition station to below the stamping head. ④ Under the action of the limiting plate and the base plate, the pressure cylinder drives the stamping head to move downward to stamp and type the first workpiece; ⑤ After the first workpiece is typed, the conveying mechanism completes its fourth cycle. During this process, the first positioning fixture on the left side of the clamping plate moves the fourth workpiece from the end of the conveyor belt to the limiting groove of the flipping component. The second positioning fixture on the left side moves the third workpiece from the limiting groove of the flipping component to the transition station. The third positioning fixture on the left side moves the second workpiece from the transition station to below the stamping head. The fourth positioning fixture on the left side moves the first workpiece from below the stamping head to the front of the conveying channel of the stacking mechanism (at the edge of the bottom plate). ⑥ After the second workpiece is typed, the conveying mechanism completes its fifth cycle. During this process, the first positioning fixture on the left side of the fixture plate moves the fifth workpiece from the end of the conveyor belt to the limiting groove of the flipping component. The second positioning fixture on the left side moves the fourth workpiece from the limiting groove of the flipping component to the transition station. The third positioning fixture on the left side moves the third workpiece from the transition station to below the stamping head. The fourth positioning fixture on the left side moves the second workpiece from below the stamping head to the front of the conveying channel of the stacking mechanism. The first workpiece enters the conveying channel of the stacking mechanism under the push of the right edge of the fixture plate. Complete one cycle of the stamping typing mechanism; 4) Material stacking ① When the workpiece enters the stacking mechanism, the conveyor belt on the conveying channel rotates under the drive of the motor. At this time, the counting sensor counts each workpiece that enters the stacking mechanism. ②When the number of workpieces reaches the preset value, the lifting cylinder drives the baffle to rise. After the baffle rises, the push cylinder drives the push plate to push the workpieces in the conveying channel into the stacking platform. ③Then the lifting cylinder drives the baffle to descend, and the top plate and vertical plate of the baffle arrange the workpieces on the stacking platform so that the front row of workpieces are arranged neatly. ④ Once the number of workpieces reaches the preset value, repeat the above actions. When the second batch of workpieces enters the stacking platform, push the first batch of workpieces deeper into the stacking platform. ⑤ Continue repeating the above actions until the workpieces fill the stacking platform. At this point, the photoelectric switch at the end of the stacking platform will send a signal to the PLC controller because it is blocked by the workpieces. The equipment will then alarm, indicating that the stacking is full and the workpieces need to be collected.
