[0044] In the present embodiment, the workpiece is a PAD product, and in other embodiments, the workpiece can be any product that needs to be dispensed, which is not limited in the present embodiment.

[0045] Specifically, the rotating jig further comprises a clamping mechanism, which is used for fixing the workpiece on the bearing plate 2. The clamping mechanism can clamp and fix the workpiece on the bearing plate 2, prevent the workpiece from shifting or falling off when rotating with the bearing plate 2, and ensure the accuracy of the position of the workpiece in the subsequent dispensing process.

[0046] In an optional embodiment, as shown in the accompanying drawings, Figure 1 The clamping mechanism comprises a plurality of limiting assemblies, each limiting assembly comprising two limiting members 511 arranged oppositely, the workpiece being arranged between the two limiting members 511, and at least one limiting member 511 being capable of moving towards the other limiting member 511 to clamp the workpiece. Through the relative movement of the two limiting members 511, the workpiece can be accurately positioned and clamped, ensuring the positional stability of the workpiece; and since at least one limiting member 511 can move towards the other limiting member 511, the limiting assembly can be applied to workpieces of different sizes and shapes, and various specifications of workpieces can be clamped and fixed by adjusting the distance between the two limiting members 511, thereby improving the versatility and flexibility of the rotating jig.

[0047] It should be noted that the number of limiting assemblies can be determined according to actual requirements, which is not limited in the present embodiment. For example, the number of limiting assemblies in the present embodiment is four, and two of them are arranged along the length direction of the bearing plate 2, and the other two are arranged along the width direction of the bearing plate 2, so that the workpiece placed on the bearing plate 2 can be clamped in the length direction and the width direction by the limiting assemblies, ensuring the omnibearing clamping of the workpiece on the bearing plate 2, and improving the positional stability and processing precision of the workpiece.

[0048] In some embodiments, the two limiters 511 in one set of limiting assemblies are capable of moving towards each other. In the present embodiment, one limiter 511 in one set of limiting assemblies is fixed on the bearing plate 2, and the other limiter 511 is capable of moving towards the fixed limiter 511. It should be noted that the specific setting manner is determined according to actual needs, and the present embodiment does not limit this.

[0049] Specifically, as shown in Figure 1 , Figure 3 The clamping mechanism further includes a second driving member 52 for driving the movement of the limiter 511. Specifically, the second driving member 52 is fixed on the side of the bearing plate 2 away from the workpiece, the limiter 511 is connected with the output end of the second driving member 52, and the bearing plate 2 is provided with a guide groove, and the limiter 511 is located in the guide groove, so that the limiter 511 can slide along the guide groove to approach or move away from the other limiter 511 under the driving of the second driving member 52.

[0050] In the present embodiment, the second driving member 52 is a pneumatic cylinder; in other embodiments, the second driving member 52 is a motor. It should be noted that any structure capable of driving the movement of the limiter 511 in the prior art can be used as the second driving member 52 in the present embodiment, and the present embodiment does not limit this.

[0051] In the present embodiment, the workpiece includes 11-inch PAD products and 12-inch PAD products, in order to ensure that the clamped PAD products can be located in the center of the bearing plate 2, the limiter 511 fixed on the bearing plate 2 is arranged in a detachable form on the bearing plate 2, and the bearing plate 2 is provided with mounting positions adapted to the 11-inch PAD products and the 12-inch PAD products. The limiter 511 can be mounted to the corresponding mounting position according to the size of the PAD product, thereby ensuring that the clamped PAD product is located in the center of the bearing plate 2.

[0052] Further, as shown in Figure 1 , two diagonal corners of the bearing plate 2 in the present embodiment are provided with avoiding grooves for avoiding the lens of the PAD product. By providing two avoiding grooves, the lens of the PAD product can be stably placed when it is located in the upper left corner or the lower right corner, without the need to disassemble and adjust the position of the bearing plate 2, which is convenient for on-site debugging and saves time. In addition, in order to prevent the PAD product from being placed upside down, the present rotating jig further includes a first foolproof member 71 and a second foolproof member 72. The first foolproof member 71 can block the avoiding groove in the upper left corner, and the second foolproof member 72 can block the avoiding groove in the lower right corner, preventing the operator from placing the PAD product upside down. If it is required to make the lens of the PAD product located in the upper left corner, the second foolproof member 72 is used to block the avoiding groove in the lower right corner.

[0053] Specifically, as shown in Figure 1As shown, the carrier plate 2 is provided with a plurality of suction members 21 in front, which are used to suck and hold the workpiece on the carrier plate 2. The suction members 21 fix the workpiece on the carrier plate 2 by generating suction force, ensuring the high stability of the workpiece during rotation and not causing damage to the surface of the workpiece. In this embodiment, the suction members 21 are vacuum suction cups.

[0054] Specifically, as shown in Figure 1 、 Figure 2 , the base assembly 1 includes a base body 11 and two vertical plates 12, which are spaced apart on the base body 11, and the two ends of the carrier plate 2 are rotatably arranged on the vertical plates 12. By arranging two spaced-apart vertical plates 12, a stable support structure is provided for the carrier plate 2, so that the carrier plate 2 can be rotated under the drive of the first driving member 3.

[0055] In this embodiment, as shown in Figure 1 、 Figure 3 , the two ends of the carrier plate 2 are provided with mounting shafts 22, which are arranged through the vertical plates 12 so that the carrier plate 2 is rotatably arranged between the two vertical plates 12. The first driving member 3 is fixedly arranged on the vertical plate 12, and its output end is connected with the mounting shaft 22. The first driving member 3 drives the mounting shaft 22 to rotate around its own axis, thereby driving the carrier plate 2 to rotate.

[0056] Further, as shown in Figure 1 、 Figure 3 , a bearing 8 is arranged between the mounting shaft 22 and the vertical plate 12. The bearing 8 can support the mounting shaft 22 and reduce the direct contact between the mounting shaft 22 and the vertical plate 12, thereby reducing the friction and wear during rotation, and making the carrier plate 2 rotate more smoothly, reducing vibration and noise. In addition, the bearing 8 can also bear radial force, ensuring that the first driving member 3 and the carrier plate 2 are not subjected to radial force, thereby improving the durability of the rotary jig.

[0057] In this embodiment, the first driving member 3 is a pneumatic cylinder; in other embodiments, the first driving member 3 is an electric motor. It should be noted that any structure capable of driving the carrier plate 2 to rotate in the prior art can be used as the first driving member 3 of this embodiment, which is not limited in this embodiment.

[0058] Specifically, as shown in Figure 1 、 Figure 2As shown, the limiting mechanism comprises an angle adjustment limiting assembly 41, which is slidably arranged on the base body 11. The bearing plate 2 can abut against the angle adjustment limiting assembly 41 to position the bearing plate 2 at a rotation angle, and the sliding angle adjustment limiting assembly 41 can change the rotation angle. Under the driving of the first driving member 3, the bearing plate 2 starts to rotate. When the bearing plate 2 rotates to abut against the angle adjustment limiting assembly 41, the bearing plate 2 cannot continue to rotate, and thus the bearing plate 2 remains at this angle. At this time, the dispensing machine can be used to dispense the workpiece. By sliding the angle adjustment limiting assembly 41 to the desired position, the bearing plate 2 can be rotated to the desired angle and remain at the desired angle.

[0059] In this embodiment, as shown in Figure 1 、 Figure 2 , the angle adjustment limiting assembly 41 comprises a fixed part 411 and a limiting part 412, which are arranged at an angle. The fixed part 411 can be slidably connected with the base body 11, and the limiting part 412 can abut against the bearing plate 2 to limit the rotation of the bearing plate 2. Specifically, a plurality of first fixing holes are arranged on the base body 11 at intervals, and a second fixing hole is arranged on the fixed part 411. The fixed part 411 is slid to connect the second fixing hole with the corresponding first fixing hole according to the required rotation angle of the bearing plate 2. Then, the first locking member 413 is sequentially inserted through the second fixing hole and the first fixing hole to fix the angle adjustment limiting assembly 41 at the desired position. When the bearing plate 2 rotates to the set angle, the limiting part 412 can abut against the bearing plate 2 to keep the bearing plate 2 at the angle.

[0060] Further, as shown in Figure 1 、 Figure 2 , the limiting mechanism further comprises a secondary limiting assembly 42, which is slidably arranged on one side of the angle adjustment limiting assembly 41. The secondary limiting assembly 42 is used to limit the movement of the angle adjustment limiting assembly 41. When the bearing plate 2 rotates to abut against the angle adjustment limiting assembly 41, a certain impact force is generated. The secondary limiting assembly 42 can limit the movement of the angle adjustment limiting assembly 41 to prevent the angle adjustment limiting assembly 41 from being displaced under the impact force.

[0061] In this embodiment, as shown in Figure 1 、 Figure 2 , the secondary limiting assembly 42 comprises a mounting seat 421, which is slidably arranged on the base body 11 and located on one side of the angle adjustment limiting assembly 41. A limiting screw 422 is arranged in the mounting seat 421. The position of the mounting seat 421 is adjusted to make the end of the limiting screw 422 abut against the fixed part 411 of the angle adjustment limiting assembly 41. Then, a second locking member 423 is used to fix the mounting seat 421 on the base body 11.

[0062] Specifically, as shown in Figure 1、 Figure 2 As shown, the limiting mechanism further comprises a horizontal limiting member 43, which can limit and support the bearing plate 2 to be in a horizontal position. Specifically, the horizontal limiting member 43 is located at one side of the bearing plate 2 to prevent interference caused by rotation of the bearing plate 2.

[0063] Specifically, as shown in Figure 1 、 Figure 2 The rotary jig further comprises a buffer assembly 6, which is slidably arranged on the base body 11 and used to provide buffering when the bearing plate 2 abuts against the angle adjusting limiting assembly 41. When the bearing plate 2 rotates to abut against the angle adjusting limiting assembly 41, the buffer assembly 6 can effectively absorb impact energy, reduce direct collision between the bearing plate 2 and the angle adjusting limiting assembly 41, and prolong the service life of the rotary jig.

[0064] Specifically, as shown in Figure 1 、 Figure 2 The buffer assembly 6 comprises a bracket base 61 and a rotating component 62, the rotating component 62 is rotatably arranged on the bracket base 61, the bracket base 61 is slidably arranged on the base body 11, and an oil pressure buffer 63 is arranged on the rotating component 62, which can provide buffering when the bearing plate 2 abuts against the angle adjusting limiting assembly 41. After sliding the bracket base 61 to the desired position and fixing it, the rotating component 62 is rotated to the appropriate position. It should be noted that during use, the rotating component 62 needs to be adjusted according to the angle at which the bearing plate 2 needs to be rotated, so that the bearing plate 2 is parallel to the rotating component 62 when it abuts against the angle adjusting limiting assembly 41, at which time the oil pressure buffer 63 can work normally and is not prone to jamming or failure.

[0065] In this embodiment, as shown in Figure 1 The rotary jig further comprises a sensing assembly 9, which comprises a sensor 91 and a sensing member 92, the sensor 91 is arranged on the inner side of the main plate, and the sensing member 92 is arranged on the bearing plate 2. The sensing member 92 can be sensed by the sensor 91, and the positions of the sensor 91 and the sensing member 92 can be set according to the angle at which the bearing plate 2 needs to be rotated, so that when the bearing plate 2 is rotated to the position, the sensor 91 can sense the sensing member 92, so that the operator can confirm that the bearing plate 2 has been rotated to the position, preventing the situation that the subsequent dispensing cannot be smoothly carried out due to the error of the rotation angle of the bearing plate 2.

[0066] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
