[0030] This application proposes a positioning device, referring to... Figures 1 to 3The positioning device includes: a conveying mechanism comprising two parallel conveyor belts 11; a pushing mechanism 20 comprising multiple pushing members 21 disposed between the two conveyor belts 11, the pushing members 21 being arranged along the conveying direction of the conveyor belts 11, and the pushing mechanism 20 further comprising a first driving member 22 for driving the pushing members 21 to move synchronously along the conveying direction; a lifting mechanism 30 disposed below the conveyor belts 11 for driving the pushing members 21 to lift and lower; and a positioning mechanism 40 comprising clamping members 41 disposed on the outer sides of the two conveyor belts 11 facing away from each other, and a second driving member 42 for driving the clamping members 41 on both sides to move toward the conveyor belts 11 to center and clamp workpiece A; the pushing members 21 are located between the clamping members 41 on both sides, and the clamping members 41 can clamp multiple workpieces A synchronously.

[0031] In this embodiment, the positioning device includes a conveying mechanism, a pushing mechanism 20, a lifting mechanism 30, and a positioning mechanism 40. The conveying mechanism includes two parallel conveyor belts 11. The pushing mechanism 20 includes multiple pushing members 21 arranged between the two conveyor belts 11 and along the conveying direction, and a first driving member 22 for driving the pushing members 21 to move along the conveying direction. The pushing members 21 can push multiple workpieces A to move synchronously, so that the workpieces A on the conveyor belts 11 maintain a set spacing. The pushing mechanism 20 is normally located below the conveyor belts 11 to avoid the workpieces A. The lifting mechanism 30 can drive the pushing members 21 to move upward to the conveyor belt, so that they can abut against the side of the workpieces A under the drive of the first driving member 22. The positioning mechanism 40 includes a clamping member 41 located on the outer side of the two conveyor belts 11 that are opposite to each other, and a second driving member 42 for driving the clamping member 41 to center and clamp the workpieces A. After the pushing members 21 complete the pushing and spacing adjustment of the multiple workpieces A, the clamping member 41 can synchronously clamp the multiple workpieces A and completely position them. The aforementioned complete positioning refers to the unique determination of the workpiece's spatial position, and that the workpiece is clamped and fixed in that position and will not easily move under external force.

[0032] Furthermore, since the clamping members 41 on both sides position the workpiece A by centering clamping, workpieces A of different sizes can be positioned. When processing different batches of workpieces A, the size of workpieces A in a single batch is consistent, but the size of workpieces A in different batches varies. The positioning mechanism can also center clamp workpieces A of different sizes before and after line changes (changing processing batches), and workpiece A can still maintain centering positioning; only the clamping distance needs to be adjusted. Of course, some second driving components, such as the clamping distance of the clamping cylinder, can also adaptively clamp based on the size of workpiece A. Therefore, the positioning device in this embodiment has a certain degree of universality for the size of workpiece A. It is worth noting that the workpiece A in this embodiment is generally a rectangular workpiece A, which can be a PCB board, glass plate, metal plate, or other material plate.

[0033] In some embodiments, refer to Figures 1 to 3 The pushing mechanism 20 also includes a first mounting frame 23, with the pushing component 21 mounted on the first mounting frame 23. The first driving component 22 includes a pushing cylinder that is driven and connected to the first mounting frame 23. The lifting mechanism 30 includes a lifting cylinder that is driven and connected to the pushing cylinder. In this embodiment, the first mounting frame 23 can be directly connected to the pushing cylinder, and then the lifting cylinder can drive the pushing mechanism 20 to move as a whole. Alternatively, the driving end of the lifting cylinder can be directly connected to the first mounting frame 23, and then the pushing cylinder can drive the lifting cylinder and the first mounting frame 23 to move as a whole. These two methods only involve switching the positions of the lifting cylinder and the pushing cylinder, and both can achieve the functions of lifting and pushing. The first mounting frame 23 includes a first mounting rod arranged along the conveying direction, and the pushing component 21 is arranged along the length direction of the first mounting rod. In this application, "multiple" refers to two or more. That is, two or more pushing components 21 can be provided on the first mounting rod. The first driving component 22 and the lifting mechanism 30 use cylinders, and the overall structure is relatively simple.

[0034] In some embodiments, refer to Figures 1 to 3 The second driving component 42 includes a clamping cylinder, which comprises two driving parts. The positioning mechanism 40 also includes a second mounting bracket 43 mounted on the driving part. Each second mounting bracket 43 has a row of clamping parts 41 arranged along the conveying direction. In this embodiment, the second mounting bracket 43 includes a T-beam 432 and a connecting part 431 connecting the lower end of the T-beam 432 to the driving part of the clamping cylinder. The crossbeam of the T-beam 432 is parallel to the conveyor belt 11 and is used to mount the clamping parts 41. The two T-beams 432 are arranged one-to-one with the two driving parts, which can complete the centering and clamping of the workpiece A in the middle. It is worth noting that in addition to using a clamping cylinder, the second driving component 42 can also use a screw mechanism including two sections with opposite rotation directions. The screw is driven by a motor to drive the nuts on the two sections to move in opposite directions, which can also achieve centering and clamping. Of course, a linkage mechanism can also be used to slide the clamping member 41 along the clamping direction, and then drive the double-headed crank to rotate through the motor located in the middle. The double-headed crank and the clamping member 41 are connected by a linkage, which can also complete the centering clamping action.

[0035] In some embodiments, refer to Figures 1 to 3The clamping members 41 on the two second mounting brackets 43 are arranged one-to-one. The one-to-one arrangement of the two rows of clamping members 41 ensures that the force is balanced when clamping workpiece A and avoids deflection. Of course, in order to further ensure stable clamping, one side of each workpiece A must abut against more than two clamping members 41. In some embodiments, the pushing mechanism 20 includes two pushing members 21, and the positioning mechanism 40 includes eight clamping members 41, with four clamping members 41 provided on each second mounting bracket 43. The two pushing members 21 can push and position the two workpieces A, completing the positioning of the two in the conveying direction. Then, the clamping members 41 located on both sides clamp and position the workpiece A in another direction. Each side of each workpiece A is clamped by a pair of clamping members 41, so that the eight clamping members 41 can clamp and position the two workpieces A.

[0036] Furthermore, the clamping member 41 is also equipped with a roller 44, the axis of rotation of which is set vertically, and the circumference of the roller 44 is used to abut against the workpiece A. The clamping member 41 does not directly clamp the workpiece A, but indirectly clamps it through the roller 44. The roller 44 can be a rubber roller 44 or a plastic roller 44, which can elastically abut against the side of the workpiece A, avoiding damage to the workpiece A caused by rigid clamping. At the same time, the setting of the roller 44 can reduce the friction on the side of the workpiece A, especially for some fragile materials such as glass plates and PCB boards, which can further reduce the risk of damage. Of course, the positioning mechanism 40 can first center and clamp the workpiece A, and control a small clamping force to ensure that the workpiece A can still move along the conveying direction under the push of the pusher. Then the pusher mechanism 20 drives the pusher 21 to push the workpiece A to move, completing the positioning in the conveying direction. The roller 44 mentioned above serves as a clamping and guiding element. Therefore, the clamping and positioning process and the pushing process can be interchanged, as long as complete horizontal positioning can be achieved.

[0037] In some embodiments, refer to Figures 1 to 3 The clamping member 41 is also provided with a strip-shaped hole 45, which is set along the driving direction of the second driving member 42. The strip-shaped hole 45 allows for easy adjustment of the position of the clamping member 41, enabling fine-tuning of the clamping force and clamping distance. Alternatively, the second mounting bracket 43 may also be provided with a through slot for mounting the clamping member 41, the length of which is parallel to the driving direction of the second driving member 42. The through slot prevents the clamping member 41 from swaying during adjustment, thus affecting positioning accuracy. Therefore, the strip-shaped hole 45 and the through slot ensure that the positioning mechanism 40 provides high positioning accuracy.

[0038] In some embodiments, refer to Figures 1 to 3The conveying mechanism also includes two third mounting brackets 12 arranged side by side, with conveyor belts 11 respectively located on the inner sides of the two third mounting brackets 12 close to each other. The conveying mechanism also includes a drive shaft 13 connecting the two conveyor belts 11, and a third driving component connected to the drive shaft 13. In this embodiment, a single motor can drive the drive shaft 13 and the two conveyor belts 11 to move synchronously. It is worth noting that the aforementioned conveyor belts 11 can be synchronous belts to further improve the transmission accuracy.

[0039] Reference Figures 1 to 3 This application also proposes a processing apparatus, which includes the aforementioned positioning device, and further includes a machine base for mounting the positioning device. The processing apparatus in this application embodiment can be a laser cutting device or a laser marking device, etc., used for cutting or marking plates. It can also be a screen printing device, capable of screen printing processing on the surface of workpiece A, etc.

[0040] In this embodiment, the working principle of the positioning device and processing equipment is as follows: The conveying mechanism in this embodiment includes two parallel conveyor belts 11, and the pushing mechanism 20 includes multiple pushing members 21 arranged between the two conveyor belts 11 and along the conveying direction, and a first driving member 22 for driving the pushing members 21 to move along the conveying direction; the pushing members 21 can push multiple workpieces A to move synchronously, so that the workpieces A on the conveyor belt 11 maintain a set spacing; the pushing mechanism 20 is normally located below the conveyor belt 11 to avoid the workpieces A; the lifting mechanism 30 can drive the pushing members 21 to move upward to the transmission belt so that they can abut against the side of the workpieces A; the positioning mechanism 40 includes a clamping member 41 arranged on the outer side of the two conveyor belts 11 that are opposite to each other, and a second driving member 42 for driving the clamping member 41 to center and clamp the workpieces A; after the pushing members 21 complete the pushing and spacing adjustment of multiple workpieces A, the clamping member 41 can synchronously clamp the multiple workpieces A and completely position them.
