[0048] The correcting device 400 is arranged at least at the bearing position 30a of the first point gluing station and comprises a correcting driving member 410 arranged on the frame 100 and a pushing member 420 drivingly connected to the correcting driving member 410, wherein the correcting driving member 410 is used to drive the pushing member 420 to move so as to push the workpiece by the pushing member 420 to correct the position of the workpiece on the bearing position 30a.

[0049] In the technical scheme, the three bearing positions 30a are arranged at the first point gluing station, the glue applying station and the second point gluing station respectively, so that the first point gluing device 210, the glue applying device 220 and the second point gluing device 230 can simultaneously process the workpieces arranged on the three bearing positions 30a respectively, and the rotating driving member 310 drives the bearing member 320 to rotate the bearing position 30a arranged at the first point gluing station to the glue applying station so as to apply glue to the workpiece by the glue applying device 220.

[0051] Further, in the embodiment, the carrier arm assembly 321 is provided with a negative pressure hole 32a, the negative pressure hole 32a is arranged at the carrier position 30a, one end of the negative pressure hole 32a is arranged at the side of the carrier arm assembly 321 close to the workpiece, and the point paste and gluing machine further comprises an air connector 330 arranged at the other end of the negative pressure hole 32a, the air connector 330 is used to extract the gas in the negative pressure hole 32a, so as to form negative pressure in the negative pressure hole 32a, thereby adsorbing the workpiece, so as to avoid the workpiece from being offset relative to the carrier position 30a when being processed; specifically, in the embodiment, the negative pressure hole 32a comprises a plurality of negative pressure holes and a suction hole in communication with the plurality of negative pressure holes, the negative pressure holes are arranged at the side of the carrier arm assembly 321 close to the workpiece, the suction hole is arranged at the side of the carrier arm assembly 321 away from the workpiece, and the air connector 330 is connected with the suction hole, in this way, only one air connector 330 can form negative pressure in the plurality of negative pressure holes, and the plurality of negative pressure holes can adsorb the workpiece at multiple positions, thereby avoiding the workpiece from being offset relative to the carrier position 30a when being processed; however, the design is not limited thereto, and in other embodiments, the carrier arm assembly is provided with a positioning recess matched with the workpiece, and the positioning recess is arranged at the carrier position for placing the workpiece.

[0052] Further, in the embodiment, the bearing arm assembly 321 comprises a bearing arm 321a drivingly connected to the rotating driving member 310 and a suction member 321b arranged on the side of the bearing arm 321a close to the workpiece, and the negative pressure hole is arranged on the suction member 321b. It can be understood that the suction member 321b can be configured in different sizes to adapt to workpieces of different sizes, and the suction member 321b can be directly replaced when the suction member 321b is damaged or blocked, which is very convenient.

[0053] Optionally, in the embodiment, the bearing arm assembly 321 is provided with a mounting hole 32b for mounting the air connector 330, and the mounting hole 32b is arranged on the side of the bearing arm assembly 321 away from the workpiece. In this way, when the rotating device 300 rotates, the air connector 330 can be avoided from being damaged by foreign matter. Specifically, in the embodiment, the mounting hole 32b is arranged on the bearing arm 321a. Of course, in other embodiments, the point glue spreading machine is also provided with a mounting shell arranged on the side of the bearing arm assembly away from the workpiece, and the mounting shell is provided with a receiving cavity for receiving the air connector.

[0054] Further, in the embodiment, the correction driving member 410 comprises a first correction cylinder 411 arranged on the rack 100 and a second correction cylinder 412 arranged on the rack 100, and the pushing member 420 comprises a first pushing member 421420 drivingly connected to the first correction cylinder 411 and a second pushing member 422420 drivingly connected to the second correction cylinder 412. The first correction cylinder 411 drives the first pushing member 421420 to push the workpiece to correct the position of the workpiece on the bearing position 30a. The second correction cylinder 412 drives the second pushing member 422420 to push the workpiece to correct the position of the workpiece on the bearing position 30a. The pushing direction of the first pushing member 421420 is different from the pushing direction of the second pushing member 422420. In this way, the correction device 400 can give the workpiece a force in at least two directions, that is, can drive the workpiece to move in at least two directions. The position of the workpiece on the bearing position 30a is adjusted by changing the force on the workpiece, so as to correct the position of the workpiece on the bearing position 30a. Specifically, in the embodiment, the two pushing directions are both in the horizontal plane and perpendicular to each other. However, the design is not limited thereto. In other embodiments, the first correction cylinder and the second correction cylinder can be replaced by a first electric cylinder and a second electric cylinder with higher precision.

It can be understood that when the pushing member 420 pushes the workpiece, it directly or indirectly gives the rotating device 300 a force, which may cause the rotating device 300 to deflect, and thus the correction effect of the correction device 400 is poor. Therefore, the stop cylinder 510 drives the mounting member 520 to stop the rotating device 300, that is, the mounting member 520 and the rotating device 300 will generate a friction force due to the force given by the pushing member 420 to the rotating device 300, to stop the rotating device 300, thereby ensuring the correction effect of the correction device 400. Specifically, in the embodiment, the first correction cylinder 411 is arranged on one side of the mounting member 520 close to the workpiece, and the second correction cylinder 412 is arranged on the other side of the mounting member 520 away from the workpiece. When the stop cylinder 510 drives the mounting member 520 to abut against the rotating device 300 to stop the rotating device 300, the side of the second pushing block close to the workpiece exceeds the side of the workpiece close to the rotating device 300, that is, the stop cylinder 510 drives the mounting member 520 to rise to stop the rotating device 300, and the correction device 400 rises to the vicinity of the workpiece with the mounting member 520 to correct the position of the workpiece. In this way, the mounting member 520 stops the rotating device 300 first, and then the correction device 400 corrects the position of the workpiece, which can ensure that the rotating device 300 will not deflect when the correction device 400 directly or indirectly gives the rotating device 300 a force, thereby ensuring the correction accuracy of the workpiece.

[0056] Optionally, in the embodiment, the point paste coating machine further comprises a feeding device 600 for feeding the workpiece to the first point paste station.

Specifically, in the embodiment, the sensor is an optical fiber sensor, and the manipulator feeds the workpiece to the first point paste station by means of negative pressure adsorption.

[0057] Optionally, in the embodiment, the point paste coating machine further comprises a discharging device configured to move the workpiece away from the rotating device 300, the discharging device is arranged on the frame 100, and in the embodiment, the discharging device is arranged corresponding to the discharging station, and the discharging device comprises a discharging manipulator configured to adsorb the workpiece by negative pressure adsorption to move the workpiece away from the rotating device 300.

[0058] Optionally, in the embodiment, the feeding device 600 further comprises a positioning cylinder arranged on either side of the conveying belt assembly along the conveying direction of the workpiece and a positioning block drivingly connected to the positioning cylinder, the positioning cylinder drives the positioning block to push the workpiece to move away from the side of the positioning cylinder, so that the sensor can detect the workpiece when the workpiece is conveyed to the end of the conveying belt assembly.

[0060] It should be noted that the first point paste device 210 and the second point paste device 230 are similar in structure and can achieve similar technical effects, and only the first point paste device 210 is described here, and the second point paste device 230 will not be described in detail, and the first point paste device 210 is referred to as a point paste device.
