It can be understood that the detachable connection of the first clamping piece 34aa and the second clamping piece 34ab is conducive to directly replacing the point pulp needle 342a when the point pulp needle 342a is damaged, thereby saving the cost of replacing the damaged components for the user. Of course, in other embodiments, the first clamping piece, the second clamping piece and the point pulp needle are integrally and non-detachably connected, so that the structural stability of the whole is improved.

[0050] Further, in the embodiment, the point pulp assembly 340a further comprises a turnover plate 343 arranged on the mounting assembly 330a, and the clamping piece is detachably connected to the turnover plate 343.

[0052] Further, in the embodiment, the support assembly 310a comprises a support plate 311a arranged on the driving module 200a and a rotating shaft 312a arranged on the support plate 311a, the point glue driving element 320a is arranged on the support plate 311a, and the mounting assembly 330a is rotatably connected to the rotating shaft 312a, the support plate 311a provides a mounting position for the point glue driving element 320a, so that the point glue driving element 320a is more firmly mounted, and the mounting assembly 330a is rotatably connected to the rotating shaft 312a, in the embodiment, the mounting assembly 330a rotates with the rotating shaft 312a, of course, in other embodiments, the mounting assembly can rotate around the rotating shaft; however, the design is not limited thereto, and in other embodiments, the support assembly comprises a support plate arranged on the driving module and a first gear fixedly arranged on the support plate, the point glue driving element is arranged on the support plate, and the mounting assembly is provided with a second gear in transmission connection with the first gear.

[0053] Further, in the embodiment, the support assembly 310a further comprises a bearing seat 313a for the rotation shaft 312a, the bearing seat 313a is arranged on the support plate 311a, and it can be understood that the bearing seat 313a provides support for the rotation shaft 312a, and the bearing seat 313a has the characteristics of rotation sensitivity, which can make the installation assembly 330a more smoothly follow the rotation of the rotation shaft 312a, so that the spot glue device can better perform the spot glue operation, specifically, in the embodiment, the bearing seat 313a is provided with two, which are arranged at both ends of the rotation shaft 312a for the rotation shaft 312a; however, the design is not limited to this, and in other embodiments, the support plate is provided with two opposite shaft holes for the rotation shaft.

If the Z-axis electric cylinder 222a is arranged on the support and the X-axis electric cylinder 221a is arranged on the Z-axis electric cylinder 222a, the Z-axis electric cylinder 222a is easy to be damaged by the gravity of the X-axis electric cylinder 221a due to the small length direction support of the Z-axis electric cylinder 222a. Therefore, in the embodiment, the support can provide good support for the X-axis electric cylinder 221a, thereby better guaranteeing the structural stability of the driving module 200a when the driving module 200a is running. In addition, the electric cylinder form of the moving part 220a can improve the displacement accuracy of the spot glue coater relative to the workpiece.

Of course, in other embodiments, the driving part can also be configured as a stepper motor.

[0056] The application further provides a point glue coating machine, which comprises a point glue coating device, and the specific structure of the point glue coating device is referred to the above-mentioned embodiments. Since the point glue coating machine adopts all the technical solutions of the above-mentioned embodiments, it has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0057] It should be noted that in the embodiment, the point glue coating machine is provided with two point glue coating devices, namely a first point glue coating device and a second point glue coating device.

[0058] Specifically, referring to Figures 1 to 9 In the embodiment, the point glue coating machine comprises:

[0059] a rack 100, which is provided with a first point glue coating station, a glue coating station and a second point glue coating station;

[0060] a first point glue coating device 210, which is arranged on the rack 100 and corresponds to the first point glue coating station;

[0061] a glue coating device 220, which is arranged on the rack 100 and corresponds to the glue coating station;

[0062] a second point glue coating device 230, which is arranged on the rack 100 and corresponds to the second point glue coating station;

[0063] a rotating device 300, which comprises a rotating driving member 310 arranged on the rack 100 and a carrying member 320 drivingly connected to the rotating driving member 310, the carrying member 320 is provided with at least three carrying positions 30a, the carrying positions 30a are used to carry workpieces, the three carrying positions 30a are arranged in sequence along the rotating direction of the carrying member 320, and the three carrying positions 30a are arranged at the first point glue coating station, the glue coating station and the second point glue coating station respectively; and

[0064] a correction device 400, which is arranged at least at the carrying position 30a located at the first point glue coating station and comprises a correction driving member 410 arranged on the rack 100 and a pushing member 420 drivingly connected to the correction driving member 410, the correction 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 carrying position 30a.

[0065] In the technical scheme, the at least three bearing positions 30a are arranged at the first sizing station, the gluing station and the second sizing station, so that the first sizing device 210, the gluing device 220 and the second sizing device 230 can simultaneously process the workpieces located at the three bearing positions 30a, respectively, and the bearing member 320 is driven by the rotating driving member 310 to rotate the bearing position 30a arranged relative to the first sizing station to the gluing station, so that the gluing device 220 can glue the processed workpiece. It can be understood that the processed workpiece located at the bearing position 30a can be sequentially sized by the first sizing device 210, glued by the gluing device 220 and sized by the second sizing device 230, thereby improving the processing efficiency of the sizing and gluing machine on the processed workpiece. The correction driving member 410 drives the pushing member 420 to push the processed workpiece placed at the sizing station, so as to correct the position of the processed workpiece on the bearing position 30a, thereby realizing the function of positioning the processed workpiece. In this way, the deviation of the sizing position of the first sizing device 210, the gluing position of the gluing device 220 and the sizing position of the second sizing device 230 from the position to be processed of the processed workpiece before correction can be basically eliminated, thereby improving the sizing and gluing accuracy of the sizing and gluing machine.

[0066] Further, in the embodiment, the bearing member 320 includes at least three bearing arm assemblies 321 drivingly connected with the rotating driving member 310, and the bearing positions 30a are arranged at the bearing arm assemblies 321. One bearing arm assembly 321 corresponds to one bearing position 30a. It can be understood that there is a gap between adjacent bearing arms 321a, that is, the form of bearing arm 321a is beneficial to save the material of the bearing member 320. On the one hand, the weight of the bearing member 320 can be reduced, thereby reducing the driving power required by the rotating driving member 310, that is, a driving member with smaller driving power can be selected to save costs. On the other hand, the gap is beneficial to provide more space for the first sizing device 210, the gluing device 220 and the second sizing device 230 to process the workpiece. For example, a sizing box for placing the processed material is arranged in the gap. The sizing box is also arranged at the rack 100, below the bearing member 320 and between the first sizing station and the gluing station. The first sizing device 210 replenishes the processed material of the first sizing device 210 by dipping the processed material in the sizing box after completing the sizing operation on the processed workpiece. Specifically, in the embodiment, the sizing and gluing machine also has a discharging station, and the bearing member 320 has four bearing arm assemblies 321 arranged at four sides of the rotating driving member 310. The four bearing arm assemblies 321 are arranged at the first sizing station, the gluing station, the second sizing station and the discharging station. However, the design is not limited thereto. In other embodiments, the bearing member can also have at least three bearing grooves, and one bearing groove corresponds to one bearing position.

[0067] Further, in the embodiment, the bearing arm assembly 321 is provided with a negative pressure hole 32a, the negative pressure hole 32a is arranged at the bearing position 30a, one end of the negative pressure hole 32a is arranged at the side of the bearing arm assembly 321 close to the workpiece, and the point glue coating machine further comprises an air joint 330 arranged at the other end of the negative pressure hole 32a, the air joint 330 is used to extract the gas in the negative pressure hole 32a, so as to form a negative pressure in the negative pressure hole 32a, so as to adsorb the workpiece, thereby avoiding the workpiece from being offset relative to the bearing position 30a when the workpiece is processed. Specifically, in the embodiment, the negative pressure hole 32a comprises a plurality of adsorption holes and an air extraction hole in communication with the plurality of adsorption holes, the adsorption holes are arranged at the side of the bearing arm assembly 321 close to the workpiece, the air extraction hole is arranged at the side of the bearing arm assembly 321 away from the workpiece, and the air joint 330 is connected to the air extraction hole. In this way, only one air joint 330 is needed to form a negative pressure in the plurality of adsorption holes, and the plurality of adsorption holes can adsorb the workpiece at multiple positions, thereby avoiding the workpiece from being offset relative to the bearing position 30a when the workpiece is processed. However, the design is not limited thereto, and in other embodiments, the bearing arm assembly is provided with a positioning groove matched with the workpiece, and the positioning groove is arranged at the bearing position for placing the workpiece.

[0068] Further, in the embodiment, the bearing arm assembly 321 comprises a bearing arm 321a drivenly connected to the rotary driving member 310 and a suction member 321b arranged at the side of the bearing arm 321a close to the workpiece, and the adsorption holes are arranged at 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 when the suction member 321b is damaged or clogged, the suction member 321b can be directly replaced, which is very convenient.

[0069] Optionally, in the embodiment, the bearing arm assembly 321 is provided with a mounting hole 32b for mounting the air joint 330, the mounting hole 32b is arranged at the side of the bearing arm assembly 321 away from the workpiece, so that the air joint 330 mounted in the mounting hole 32b can avoid being damaged by foreign matter when the rotary device 300 rotates. Specifically, in the embodiment, the mounting hole 32b is arranged at the bearing arm 321a. Of course, in other embodiments, the point glue coating machine is further provided with a mounting shell arranged at 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 joint.

[0070] Further, in the present 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, the pushing member 420 comprises a first pushing member 421 420 drivingly connected with the first correction cylinder 411 and a second pushing member 422 420 drivingly connected with the second correction cylinder 412, the first correction cylinder 411 drives the first pushing member 421 420 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 422 420 to push the workpiece to correct the position of the workpiece on the bearing position 30a, the pushing direction of the first pushing member 421 420 is different from the pushing direction of the second pushing member 422 420, thus the correction device 400 can give the workpiece force in at least two directions, that is, can drive the workpiece to move in at least two directions, and adjust the position of the workpiece on the bearing position 30a by changing the force on the workpiece, so as to correct the position of the workpiece on the bearing position 30a. Specifically, in the present embodiment, the two pushing directions are both in the horizontal plane and perpendicular to each other; however, the design is not limited thereto, and 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.

[0071] Further, in the embodiment, the point paste coating machine further comprises a stop cylinder 510 arranged on the rack 100 and a mounting member 520 drivingly connected with the stop cylinder 510, the mounting member 520 is arranged below the rotating mechanism, and the stop cylinder 510 drives the mounting member 520 to abut against the rotating device 300 to stop the rotating device 300. 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, at this time, 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.
