Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic glass production equipment, and in particular to a defective product transfer mechanism. Background Art

[0002] During the photovoltaic glass production process, finished products must be inspected and defective products removed to prevent them from flowing into subsequent production processes and wasting resources. Prior art techniques involve transferring defective products by positioning a robotic arm on the side of a conveyor. However, because the robotic arm's operating speed cannot match the conveyor's conveying rate, in practice, when a continuous stream of products is defective, the robotic arm is unable to transfer all of the defective products, causing them to flow into subsequent processes.

[0003] In order to improve the transfer efficiency of defective products, some existing transfer mechanisms (for example, the authorization announcement number is: CN221459128U, and the name is a transfer mechanism) include a main frame, on which two clamps are provided for grabbing the materials to be transported; a rotating mechanism for driving the two clamps to switch positions with each other; and a lifting mechanism for driving the two clamps to move up and down. The clamps are adjusted to the correct height by the lifting mechanism, the defective products are grabbed by the clamps, and the defective products are transferred by rotation. At the same time, after the rotation is completed, the second clamp can grab the next defective product. This setting can greatly improve the transfer efficiency. However, this mechanism drives the main shaft to rotate through a motor, and the main shaft and the main frame are directly connected to drive the main frame to rotate, which results in excessive rotation speed and prone to inaccurate positioning problems.

[0025] like Figure 1 and Figure 2 As shown, the embodiment relates to a defective product transfer mechanism, comprising: a support base 10, a driving structure 20, a grabbing structure 30 and a driven structure 40. The driving structure 20 is arranged on the support base 10, and the driving structure 20 includes a first rotating shaft. The grabbing structure 30 includes at least two groups of grabbing claws 31. The driven structure 40 includes a driving gear 41, a driven gear 42 and a mounting member 43. The driving gear 41 is sleeved on the circumferential outer side of the first rotating shaft. The driving gear 41 and the driven gear 42 are both rotatably arranged on the support base 10. The driving gear 41 and the driven gear 42 are meshed with each other, the mounting member 43 is connected to the driven gear 42, and the two groups of grabbing claws 31 are both connected to the mounting member 43.

[0026] Using the technical solution of this embodiment, the defective product transfer mechanism includes a support base 10, a drive structure 20, a gripping structure 30, and a driven structure 40. The drive structure 20 is mounted on the support base 10 and is configured to output a driving force. The drive structure 20 includes a first rotating shaft. The gripping structure 30 includes at least two sets of gripping jaws 31, which are used to grasp defective products for transfer. The driven structure 40 includes a driving gear 41, a driven gear 42, and a mounting member 43. The driving gear 41 is sleeved on the circumferential outer side of the first rotating shaft.

The two sets of grabbing jaws 31 are both connected to the mounting member 43. The mounting member 43 rotates as the driven gear 42 rotates to realize the position exchange of the grabbing jaws 31, thereby achieving efficient capture of defective products. At the same time, the meshing of the driving gear 41 and the driven gear 42 can slow down the rotation speed of the grabbing jaws 31, and the grasping positioning accuracy is higher. The technical solution of this embodiment effectively solves the problem of low grasping positioning accuracy when transferring defective products in the prior art.

[0027] like Figure 1 As shown, in some embodiments, the driven structure 40 further includes two sets of bearing seats 44, bearings, and a second rotating shaft 45. The two sets of bearing seats 44 and the two sets of bearings are arranged in a one-to-one correspondence, and the bearings are arranged in the bearing seats 44. Both sets of bearing seats 44 are arranged on the support seat 10. The first rotating shaft is inserted into the first set of bearings, and the second rotating shaft 45 is inserted into the second set of bearings, which plays a role in reducing friction and makes the first and second rotating shafts 45 more stable during rotation. The driven gear 42 is sleeved in the second rotating shaft 45. The second rotating shaft 45 rotates under the drive of the driven gear 42. The diameter of the driven gear 42 is larger than the diameter of the driving gear 41. The purpose of this arrangement is to slow down the rotation speed of the grasping jaw 31, so that the positioning accuracy is high when grasping defective products.

[0028] like Figure 1 As shown, in some embodiments, the driven structure 40 also includes a third rotating shaft 46, a first pulley, a second pulley and a belt 47. The first pulley is arranged on the circumferential outer side of the second rotating shaft 45, and the first pulley rotates synchronously with the rotation of the second rotating shaft 45. The second pulley is arranged on the circumferential outer side of the third rotating shaft 46.

[0030] like Figure 1 As shown, in some embodiments, the grasping structure 30 further includes two sets of lifting cylinders 32, which are provided in a one-to-one correspondence with the two sets of grasping jaws 31. The cylinder body of the first set of lifting cylinders 32 is connected to the third rotating shaft 46 and can rotate with the rotation of the third rotating shaft 46. The cylinder rod of the first set of lifting cylinders 32 is connected to the first set of grasping jaws 31 to achieve height adjustment of the first set of grasping jaws 31. The cylinder body of the second set of lifting cylinders 32 is connected to the second mounting plate 432, and the cylinder rod of the second set of lifting cylinders 32 is connected to the second set of grasping jaws 31 to achieve height adjustment of the second set of grasping jaws.

[0031] It should be noted that as the third rotating shaft 46 rotates, every time the two groups of grabbing jaws 31 exchange positions, the first group of grabbing jaws 31 rotates 360° driven by the third rotating shaft 46. At this time, the grabbing jaws 31 can match the defective products on the conveying device 100, and are more secure when grabbing.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the driving structure 20 also includes a driving motor 21, a driving shaft and a coupling 22. The driving motor 21 and the driving shaft are connected in a transmission manner, and the coupling 22 is connected to the driving shaft and the first rotating shaft. The driving motor outputs a driving force, and the driving shaft drives the first rotating shaft to rotate. The driving gear 41 rotates with the rotation of the first rotating shaft, and the driven gear 42 engages with the driving gear 41 to realize rotation. The first mounting plate 431 rotates with the rotation of the driven gear 42, thereby realizing position exchange and transferring defective products.

[0033] like Figure 1 and Figure 2As shown, in some embodiments, the support seat 10 includes a first support plate 11, a second support plate 12 and a connecting rod 13. The first support plate 11 and the second support plate 12 are connected by the connecting rod 13. The first support plate 11 has a through hole, and the first rotating shaft is passed through the through hole. The second support plate 12 has a mounting hole, and the drive motor 21 is passed through the mounting hole and connected to the inner wall of the mounting hole. The first support plate 11 supports the driven structure 40, and the second support plate 12 supports the driving structure 20. The second support plate can be connected to the support frame to place the defective product transfer mechanism on one side of the conveying device 100 for easy grasping.

[0034] In some embodiments, the grabbing jaws 31 are pneumatic jaws.

[0035] In some embodiments, the defective product transfer mechanism also includes an external gas source, a connecting pipe and a solenoid valve. The gas source is connected to the grabbing clamp 31 through the connecting pipe. The gas source delivers high-pressure gas to enable the grabbing clamp 31 to grab. The solenoid valve is set on the connecting pipe, and the gripping force of the grabbing clamp 31 can be controlled by controlling the amount of gas delivered.

[0036] It should also be noted that the gas source is also connected to the lifting cylinder 32, and high-pressure gas is delivered to the lifting cylinder through the gas source to achieve adjustment of the lifting height.

[0037] In some embodiments, the defective product transfer mechanism further includes a control module, which includes an inspection camera, a data processor, and a PLC controller. The inspection camera is electrically connected to the data processor, which is electrically connected to the PLC controller. The PLC controller is electrically connected to the drive structure 20, the air source, and the solenoid valve. Specifically, the PLC controller is electrically connected to the drive motor 21.

[0038] The specific control process is as follows: the detection camera detects the products on the conveying device 100 and transmits the detection data to the data processor. The data processor determines whether the product is a defective product and transmits the processing result to the PLC controller. The PLC controller controls the opening of the solenoid valve to adjust the amount of gas output by the gas source, thereby realizing the grasping of defective products. When all continuous products are defective products, the PLC controller controls the drive motor 21 to work, realize position exchange, and realize high-efficiency grasping of defective products.
