DETAILED DESCRIPTION

[0021] The utility model will be combined with specific implementation and description drawings to make further detailed description to the utility model and its beneficial effect, but, the specific implementation of the utility model is not limited to this.

[0022] As shown in Figure 1 and Figure 2 , it is the glue wiping mechanism of the glue dispensing machine, applied to glue dispensing equipment, comprising a glue wiping bottom plate 5, a dust-free cloth 6, a dust-free cloth placing table 7, a material receiving assembly 1, a material placing assembly 2, a tensioning detection assembly 3 and a glue cup assembly 4, the material receiving assembly 1 comprises a stepping motor 11, a motor shaft 12, a material receiving disc 13 and a first pressing cover 14, the material placing assembly 2 comprises a permanent magnet brake 21, a brake shaft 22, a material placing disc 23 and a second pressing cover 24, the tensioning detection assembly comprises a first photoelectric sensor 31, a second photoelectric sensor 32, a tensioning wheel 33 and an inductive sheet 34, and the glue cup assembly 4 comprises a glue cup fixing plate 41 and a glue cup 42.

[0023] Preferably, the stepper motor 11 of the receiving assembly 1 is mounted on the adhesive wiping base plate 5 and connected to the receiving tray 13 via the motor shaft 12. The lint-free cloth 6 is fixed on the receiving tray 13 using the first clamping cover 14.

[0024] Preferably, the permanent magnet brake 21 of the feeding assembly 2 is mounted on the adhesive wiping base plate 5 and connected to the feeding tray 23 through the brake shaft 22. The lint-free cloth 6 is fixed on the feeding tray 23 using the second clamping cover 24.

[0025] Preferably, the tensioning wheel 33 of the tensioning detection assembly 3 tensions the cleanroom cloth 6. The tensioning wheel 33 is connected to the tensioning wheel shaft 37 through the first bearing 35 and the second bearing 36 in the middle. The outer side of the first bearing 35 is fixed by the shaft retaining ring 38. The tensioning wheel shaft 37 is bolted to the adhesive wiping base plate 5.

[0026] Preferably, the sensing element 34 of the tension detection component 3 is mounted on the tension wheel shaft 37, and a first photoelectric sensor 31 is mounted on the adhesive wiping base plate 5 next to it for monitoring the movement status of the cleanroom cloth; a second photoelectric sensor 32 is installed on the underside of the cleanroom cloth 6 placement table for empty material alarm.

[0027] Preferably, the glue cup fixing plate 41 of the glue cup assembly 4 is installed flush with the cleanroom cloth placement table 7, and the glue cup 42 is placed on the glue cup fixing plate 41.

[0028] The specific working principle is that a glue-applying mechanism of a dispensing machine, such as... Figure 1 , Figure 2 As shown, the permanent magnet brake 21 passes through the adhesive wiping base plate 5 and is connected to the feeding tray 23. The stepper motor 11 passes through the adhesive wiping base plate 5 and is connected to the receiving tray 13 via the motor shaft 12. A new roll of cleanroom wipes is placed on the feeding tray 23 and pressed down with the second clamping cover 24. One end of the cleanroom wipes is pulled out, passes through the tension wheel 33 and the cleanroom wipe placement platform 7, and is installed on the receiving tray 13. The first clamping cover 14 is then placed on top to complete the installation of the cleanroom wipes.

[0029] The cup fixing plate 41 has two circular holes. The outer diameter of the cup 42 is slightly larger than the circular holes, so the cup can be placed on the cup fixing plate 41 more easily and can be easily removed and replaced.

[0030] When the dispensing head moves and comes into close contact with the cleanroom cloth above the cleanroom cloth placement table 7, the adhesive is wiped off. The stepper motor 11 rotates at a certain angle, causing the cleanroom cloth to move a certain distance relative to the dispensing head. Because the feeding tray 23 is connected to the permanent magnet brake 21, it hinders the movement of the cleanroom cloth, keeping it taut and cleaning away any remaining adhesive from the outside of the dispensing head. If the machine is not used for dispensing for a period of time, to prevent adhesive from solidifying on the dispensing head, any remaining adhesive inside the dispensing head must first be sprayed clean above the adhesive cup 42 before moving to the cleanroom cloth placement table 7. The stepper motor 11 then drives the cleanroom cloth to clean the dispensing head.

[0031] Specifically, the tensioning assembly sectional view of the glue wiping mechanism of the glue dispensing machine is as shown in Figure 3 The tensioning wheel 33 is in close contact with the dust-free cloth, and the tensioning wheel 33 is connected with the tensioning wheel shaft 37 through the first bearing 35 and the second bearing 36 in the middle, so that the tensioning wheel 33 can move relatively smoothly relative to the tensioning wheel shaft 37. The first bearing is fixed through the shaft retainer 38 on the outside, and the tensioning wheel shaft is bolted with the glue wiping bottom plate. The inductive sheet 34 is tightly connected with the tensioning wheel 33 through small bolts, the installation position of the first photoelectric sensor 31 is matched with the inductive sheet 34, and the number of rotation of the inductive sheet can be recorded to calculate the running speed of the dust-free cloth. In combination with the available length of each roll of dust-free cloth, when the dust-free cloth is about to be used up, the alarm can be sent in time to inform the operator to replace the dust-free cloth.

[0032] Further, if the dust-free cloth has been used up, but the data recorded by the first photoelectric sensor does not make the equipment alarm in advance, the second photoelectric sensor 32 also monitors the dust-free cloth. When the second photoelectric sensor 32 does not detect the dust-free cloth in the installed position, an alarm will also be sent to inform the operator to replace the dust-free cloth. Double insurance ensures that the empty material alarm function of the equipment is normally used.

[0033] As described above, the glue dispensing machine provided by the utility model comprises an automatic glue wiping mechanism, the automatic glue wiping mechanism comprises a material receiving assembly 1, a material placing assembly 2, a tensioning wheel 33 and a dust-free cloth placing table 7, the material receiving assembly 1 comprises a material receiving disc 13, a first pressing cover 14 and a stepping motor 11 for driving and speed control, the material placing assembly 2 comprises a material placing disc 23, a second pressing cover 24 and a permanent magnet brake 21 for increasing damping, and further comprises a full-automatic empty material monitoring double-alarm device, a first detection device is arranged at the tensioning wheel 33 and used to detect the conveying speed and use condition of the dust-free cloth to send a first heavy material replacement alarm signal when the dust-free cloth is about to be used up, and a second detection device is arranged at the dust-free cloth placing table 7 and used to detect the arrival condition of the dust-free cloth on the dust-free cloth placing table to send a second heavy material replacement alarm signal when there is no material.

[0034] Preferably, the first detection device and the second detection device adopt photoelectric sensors, that is, the first detection device comprises a first photoelectric sensor 31 and the second detection device comprises a second photoelectric sensor 32, and the second detection device is used to detect whether there is dust-free cloth on the dust-free cloth placing table 7 to send an alarm signal in time when there is no material.

[0035] Preferably, the first detection device is matched with the inductive sheet 34, the inductive sheet 34 is fixedly connected with the tensioning wheel 33, and the number of rotation of the inductive sheet 34 is recorded to calculate the use speed of the dust-free cloth in combination with the available length of each roll of dust-free cloth, so that an alarm signal can be sent in time when the dust-free cloth is about to be used up.
