[0017] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Please refer to Figure 1 、 Figure 2, the present utility model provides a duplex dispensing and wiping mechanism, including: a duplex dispensing mechanism 1, and a wiping mechanism 2 disposed below the duplex dispensing mechanism 1. The duplex dispensing mechanism 1 includes two groups of dispensing heads 11. The wiping mechanism 2 includes: a frame plate 21 disposed below the duplex dispensing mechanism 1, and two groups of wiping assemblies 22 disposed on the frame plate 21. The two groups of wiping assemblies 22 respectively correspond to the two groups of dispensing heads 11 of the duplex dispensing mechanism 1. The wiping assembly 22 includes: a clamping jaw cylinder 221 disposed on the frame plate 21, and a cleaning wheel 222 disposed on the clamping jaw cylinder 221. The clamping jaw cylinder 221 drives the cleaning wheel 222 to actively clamp the dispensing head 11.

[0019] After the dispensing head 11 completes the dispensing work on the product, the duplex dispensing mechanism 1 moves the dispensing heads 11 to the corresponding positions of the wiping assemblies 22 respectively, and moves the dispensing heads 11 to the corresponding height positions of the cleaning wheels 222 on the clamping jaw cylinder 221. The clamping jaw cylinder 221 is started, and the cleaning wheel 222 clamps the dispensing head 11, and the dispensing head 11 is moved up and down at the clamping position of the cleaning wheel 222, so as to realize the cleaning of the dispensing head 11. After using different specifications of dispensing heads 11 for dispensing work, the clamping jaw cylinder 221 can drive the cleaning wheel 222 to clamp and wipe the dispensing head 11, ensuring the wiping effect on the dispensing head 11 and improving the versatility. Or different specifications of cleaning wheels 222 can be replaced according to the needle shape or nozzle size of the dispensing head 11, so as to meet the corresponding wiping work requirements.

[0020] In some embodiments, the wiping mechanism 2 further includes: a unwinding device 23 and a winding device 24 disposed on the frame plate 21. A dust-free belt is movably sleeved on the unwinding device 23. The dust-free belt extends out of the unwinding device 23, passes through the cleaning wheels 222 of the wiping assembly 22 in sequence, and is wound on the winding device 24. When wiping the dispensing head 11 through the wiping assembly 22, the winding device 24 is used to traction and pull the dust-free belt to move, so as to meet the work of wiping the end and periphery of the dispensing head 11. The cleaning wheel 222 clamps the dust-free belt and the dispensing head 11, increasing the friction between the dust-free belt and the dispensing head 11. While the dispensing head 11 moves up and down, the traction force provided by the winding device 24 is used to pull the dust-free belt to realize the wiping action, thereby effectively improving the wiping effect.

[0021] One group or two groups are respectively provided for the unwinding device 23 and the winding device 24.

[0022] When a set of unwinding device 23 and winding device 24 are provided on the frame plate 21, the unwinding device 23 and the winding device 24 can be arranged on the same side of the frame plate 21, or the unwinding device 23 and the winding device 24 can be respectively arranged on both sides of the frame plate 21. A group of dust-free belts are used to pass through the two wiping assemblies 22 at the same time, so as to reduce the space occupied by the overall equipment. Preferably, arranging the unwinding device 23 and the winding device 24 on the same side of the frame plate 21 can effectively reduce the space occupied by the whole, and leave one side of the frame plate 21 empty, which is convenient for the duplex dispensing mechanism 1 to move between the dispensing station and the wiping station, and avoid collision between the duplex dispensing mechanism 1 and the unwinding device 23 or the winding device 24 during the movement process.

[0023] When two sets of unwinding devices 23 and winding devices 24 are provided on the frame plate 21, the unwinding device 23, the winding device 24 and the wiping assembly 22 are in one-to-one correspondence, so as to ensure that during the wiping process, the dust-free belt will not adhere to the glue residue after the dispensing head 11 is wiped by the other wiping assembly 22, avoid the glue residue from contaminating the corresponding dispensing head 11 of the subsequent wiping assembly 22 and affecting the wiping effect, and can improve the utilization rate of each roll of dust-free belt and avoid waste of resources.

[0024] In some embodiments, the winding device 24 includes: a mounting plate 241 provided on the frame plate 21, a winding driving mechanism 242 provided on the mounting plate 241, a driving wheel 243 provided at the output end of the winding driving mechanism 242, a pressure wheel movably provided beside the driving wheel 243, and a winding shaft provided on the mounting plate 241. The dust-free belt passes through the contact surface between the driving wheel 243 and the pressure wheel 244 and is wound on the winding shaft 245. During feeding, the dust-free belt is passed through between the driving wheel 243 and the pressure wheel 244, the dust-free belt is pressed between the pressure wheel 243 and the driving wheel 244 by the pressure wheel 244, and the winding driving mechanism 241 is started to make the driving wheel 244 rotate, so as to drive the dust-free belt to be transported forward through the action of friction and wind the dust-free belt on the winding shaft 245. In some embodiments, the winding driving mechanism 242 adopts a motor, and the driving wheel 243 is driven to rotate by the operation of the motor.

[0025] In some embodiments, a crank 246 is hinged on the mounting plate 241. One end of the crank 246 is hinged on the mounting plate 241, and the other end is rotatably connected to the pressure wheel 244. By providing the crank, it is convenient to adjust the relative position between the pressure wheel 244 and the driving wheel 243, so as to facilitate the installation and replacement of the dust-free belt. At the same time, it is convenient to adjust the pressing effect between the pressure wheel 244 and the driving wheel 243, so as to adjust the traction force applied to the dust-free belt.

[0026] In some embodiments, a number of guide wheels 25 are provided on the frame plate 21, and the guide wheels 25 are respectively arranged beside the unwinding device 23, the winding device 24, and the wiping assembly 22. The guide wheels 25 provide guiding and deviation correction for the moving path of the dust-free belt, ensuring the running stability of the dust-free belt during movement, and can tighten the dust-free belt to ensure the wiping effect on the dispensing head 11.

By driving the dispensing head mounting plate 13 through the Z-axis moving module 12, the dispensing head 11 can move up and down along the Z-axis direction, so as to drive the dispensing head 1 to extend into the position between the cleaning wheels 222 of the corresponding wiping assembly 22, facilitating the effective wiping and cleaning work of the dispensing head 11 by the cleaning wheels 222.

[0028] In some embodiments, please refer to Figure 1 , Figure 3 , a number of silver paste dispensing heads 14 are provided on the duplex dispensing mechanism 1, the silver paste dispensing heads 14 are arranged beside the dispensing heads 11, and a silver paste bubble needle box 26 is correspondingly arranged on the frame plate 21 for the silver paste dispensing heads 14. The silver paste dispensing process is a common process method in the manufacturing of electronic components. By uniformly mixing silver powder and organic adhesive to form silver paste, and then using the silver paste dispensing heads 14 to perform dispensing work on the wire joints. After the silver paste dispensing heads 14 perform dispensing work, in order to ensure the effect of subsequent dispensing work, generally, the silver paste dispensing heads 14 need to be immersed in the silver paste. Therefore, by arranging the silver paste bubble needle box 26 on the frame plate 21, it is convenient to immerse the silver paste dispensing heads 14 in the silver paste bubble needle box 26 while the dispensing heads 11 are being wiped and cleaned, so that the front ends of the silver paste dispensing heads 14 are adhered with silver paste, facilitating subsequent silver paste dispensing work.
