[0018] To provide a better understanding of the purpose, structure, features and functions of this utility model, detailed descriptions are provided below with reference to the embodiments.

[0019] Please refer to Figures 1-2 , Figure 1 This is a schematic diagram of the residual adhesive cleaning and recycling device of this utility model when the adhesive application head is performing adhesive application operations. Figure 2 This is a schematic diagram of the residual adhesive cleaning and recycling device of this utility model when the adhesive applicator is not performing adhesive application. Figure 1 As shown, this utility model proposes a residual adhesive cleaning and recycling device 1 for cleaning and recycling residual adhesive generated by the coating head 2 during the operation of a sealing machine. The residual adhesive cleaning and recycling device 1 includes a residual adhesive adsorption connector 11, a residual adhesive recycling bottle 12, a vacuum pump 13, and a drive assembly 14. The residual adhesive adsorption connector 11 has an adhesive suction hole 111, the shape and size of which match the shape and size of the coating head 2. The residual adhesive recycling bottle 12 is connected to the adhesive suction hole 111 of the residual adhesive adsorption connector 11 through a first connecting pipe 15, and the vacuum pump 13 is connected to the residual adhesive recycling bottle 12 through a second connecting pipe 16. The drive assembly 14 is connected to the residual adhesive adsorption connector 11 and is used to drive the residual adhesive adsorption connector 11 to move.

[0020] like Figure 1 As shown, when the glue applicator 2 is performing the glue applicator operation, the residual glue adsorption connector 11 is located in the first position and separated from the glue applicator 2 to ensure the normal operation of the glue applicator 2; as Figure 2As shown, when the glue head 2 completes the glue coating operation of the current product, the driving assembly 14 drives the residual glue adsorption connector 11 to move to the second position to be tightly sleeved with the glue head 2, so as to timely and accurately adsorb and recover the residual glue on the glue head 2. After the residual glue adsorption connector 11 is tightly sleeved with the glue head 2, the vacuum pump 13 is started for a preset time to adsorb the residual glue on the glue head 2 and transport the residual glue to the residual glue recovery bottle 12 through the first connecting pipe 15, so as to complete the cleaning and recovery of the residual glue. The residual glue cleaning and recovery device 1 of the utility model can timely and effectively clean the residual glue of the glue head 2, improve the glue coating condition, avoid the abnormal glue drop in the glue coating operation process, and the recovered residual glue can be used secondly, so as to effectively save the consumption of glue and reduce the production cost.

[0021] Further, as shown in Figure 1 and Figure 2 , when the glue head 2 performs the glue coating operation, the driving assembly 14 drives the residual glue adsorption connector 11 to move to the first position and be separated from the glue head 2, the glue head 2 coats glue along the preset path, and the driving assembly 14 also drives the residual glue adsorption connector 11 to move along the preset path to keep synchronous movement with the glue head 2. In an embodiment, the glue head 2 is fixedly connected with the driving assembly 14, when the glue head 2 coats glue along the preset path, the glue head 2 drives the driving assembly 14 to synchronously move, and the driving assembly 14 further drives the residual glue adsorption connector 11 to move along the preset path.

[0022] In an embodiment, the driving assembly 14 comprises a first driving part 141 and a second driving part 142, the first driving part 141 is used to drive the residual glue adsorption connector 11 to move along the first direction F1, and the second driving part 142 is used to drive the residual glue adsorption connector 11 to move along the second direction F2, wherein the first direction F1 intersects with the second direction F2. Further, the first direction F1 is perpendicular to the second direction F2. In the utility model, when the glue head 2 completes the glue coating operation of the current product, the first driving part 141 and / or the second driving part 142 cooperates to drive the residual glue adsorption connector 11 to move to the second position to be tightly sleeved with the glue head 2, by the arrangement of the first driving part 141 and the second driving part 142, the residual glue adsorption connector 11 timely adsorbs the residual glue on the glue head 2 with high precision, and the accuracy of the residual glue cleaning and recovery device 1 is improved. In an embodiment, the first direction F1 is a linear direction, and the embodiment shown in Figure 1 and Figure 2 , the first direction F1 can be a vertical direction, and the second direction F2 is a horizontal direction, but it is not limited thereto.

[0023] In an embodiment, the product to be coated with glue is a display panel, and the display panel is horizontally placed, the glue head 2 acts in a straight line to perform the glue coating operation along the four peripheral sides of the display panel, and the residual glue adsorption connector 11 is tightly sleeved with the glue head 2 to adsorb the residual glue on the glue head 2. Figure 1 and Figure 2In the shown embodiment, the preset path is a plane closed shape formed in a horizontal direction and a direction perpendicular to the paper surface, and at this time, the excess glue adsorption joint 11 is located at the first position relative to the glue applying head 2, and the vertical projections of the excess glue adsorption joint 11 on the first direction F1 and the second direction F2 do not overlap with the vertical projections of the glue applying head 2 on the first direction F1 and the second direction F2, respectively, for example, the excess glue adsorption joint 11 is located obliquely above or below the glue applying head 2, so as to avoid affecting the glue applying operation of the glue applying head 2 when the excess glue adsorption joint 11 moves synchronously with the glue applying head 2.

[0024] In an embodiment, the excess glue recovery bottle 12 is provided with a liquid level sensor 121 for detecting the liquid level of the glue in the excess glue recovery bottle 12. The liquid level sensor 121 can be located on the inner wall of the excess glue recovery bottle 12, but is not limited thereto. In actual operation, the excess glue cleaning and recovery device 1 of the present application further comprises an alarm (not shown), and the liquid level sensor 121 is electrically connected to the alarm (not shown). When the liquid level sensor 121 detects that the glue in the excess glue recovery bottle 12 reaches a preset liquid level, the alarm sends an alarm to prompt the staff to replace the excess glue recovery bottle 12 in time, so as to avoid the glue in the excess glue recovery bottle 12 being too full to cause the vacuum pump 13 to be damaged due to back suction when the vacuum pump 13 is started.

[0025] In an embodiment, the excess glue cleaning and recovery device 1 further comprises a first detection assembly (not shown), which comprises a first emitting part and a first receiving part. One of the first emitting part and the first receiving part is arranged on the glue applying head 2, and the other of the first emitting part and the first receiving part is arranged on the excess glue adsorption joint 11. For example, the first emitting part is arranged on the glue applying head 2, and the first receiving part is arranged on the excess glue adsorption joint 11. When the glue applying head 2 starts the glue applying operation, the first receiving part on the excess glue adsorption joint 11 receives the optical signal from the first emitting part on the glue applying head 2, so that the first driving part 141 drives the excess glue adsorption joint 11 to move along the preset path synchronously with the glue applying head 2. For another example, the first emitting part is arranged on the glue applying head 2 and is used for emitting an optical signal, and the first receiving part is arranged on the excess glue adsorption joint 11 and is used for receiving the optical signal. When the glue applying head 2 starts the glue applying operation, the first receiving part on the excess glue adsorption joint 11 cannot receive the optical signal from the first emitting part on the glue applying head 2 due to the shielding of the current product, and accordingly generates a control signal. The control signal can drive the first driving part 141 to drive the excess glue adsorption joint 11 to move along the preset path (the movement is synchronous with the glue applying head 2). When the glue applying head 2 completes the glue applying operation of the current product, the current product is moved away, the first receiving part receives the optical signal from the first emitting part and generates another control signal. The another control signal can drive the second driving part 142 to drive the excess glue adsorption joint 11 to move along the second direction F2 and tightly wrap the glue applying head 2.

[0026] In an embodiment, the excess glue cleaning and recycling device 1 further comprises an elastic member 17, two ends of the elastic member 17 are connected with the second driving part 142 and the excess glue adsorption connector 11 respectively, the elastic member 17 is, for example, a telescopic spring and has a certain rigidity, when the second driving part 142 drives the excess glue adsorption connector 11 to move along the second direction F2 to be tightly sleeved with the glue applying head 2, the elastic member 17 can provide a buffering effect, avoiding the damage of the excess glue adsorption connector 11 to the glue applying head 2 caused by collision.

[0027] In an embodiment, the cross section of the glue adsorption hole 111 is circular, and the inner wall surface of the glue adsorption hole 111 is smooth, thereby reducing the glue attached to the inner wall surface of the glue adsorption hole 111. In another embodiment, the excess glue adsorption connector 11 is made of rubber material, thereby enhancing the tightness of the connection when the excess glue adsorption connector 11 is tightly sleeved with the glue applying head 2, and further improving the working efficiency of the excess glue cleaning and recycling device 1, and providing further buffering effect when the excess glue adsorption connector 11 is tightly sleeved with the glue applying head 2.

[0028] In an embodiment, continuing to refer to Figure 1 and Figure 2 , the excess glue adsorption connector 11 has opposite first and second end surfaces D1 and D2, and a first surface S1 connecting the first and second end surfaces D1 and D2, the elastic member is connected to the second end surface D2, the glue adsorption hole 111 is located inside the excess glue adsorption connector 11 and comprises a first part 1111 and a second part 1112 connected with each other, the first part extends along the second direction F2 and is exposed from the first end surface D1, the shape and size of the first part 1111 are matched with the shape and size of the glue applying head 2, the second part 1112 extends along a third direction and is exposed from the first surface S1 to connect the first connecting pipe 15, wherein the third direction intersects with the second direction F2. In this embodiment, the third direction is parallel to the first direction F1, but is not limited thereto.

[0029] In an embodiment, the excess glue recycling bottle 12 comprises a bottle body and a bottle cap which are detachably connected, the first connecting pipe 15 and the second connecting pipe 16 are inserted into the excess glue recycling bottle 12 from the bottle cap, the end of the second connecting pipe 16 inserted into the excess glue recycling bottle 12 is higher than the end of the first connecting pipe 15, which can avoid the glue transported from the end of the first connecting pipe 15 into the excess glue recycling bottle 12 being directly sucked by the vacuum pump 13, and the installation height of the liquid level sensor 121 is higher than the end of the first glass pipe 152 and lower than the end of the second glass pipe 162.

[0030] In an embodiment, the first connecting pipe 15 comprises a first hose 151 connected with the outlet of the glue suction hole 111 of the residual glue suction head 11 and a first glass pipe 152 in L shape, one end of which is inserted into the residual glue recovery bottle 12 and the other end of which is connected with the first hose 151. Correspondingly, the second connecting pipe 16 comprises a second hose 161 connected with the vacuum pump 13 and a second glass pipe 162 in L shape, one end of which is inserted into the residual glue recovery bottle 12 and the other end of which is connected with the second hose 161.

[0031] In an embodiment, the residual glue cleaning and recovery device 1 further comprises a controller (not shown), for example, a programmable logic controller (PLC). The glue applying head 2, the driving assembly 14 and the vacuum pump 13 are electrically connected with the controller. When the glue applying head 2 performs the glue applying operation, the glue applying head 2 sends a first signal to the controller, and the controller controls the driving assembly 14 to drive the residual glue suction head 11 to move to the first position and separate from the glue applying head 2 after receiving the first signal from the glue applying head 2. When the glue applying head 2 completes the glue applying operation for the current product, the controller receives a second signal from the glue applying head 2 and controls the driving assembly 14 to drive the residual glue suction head 11 to move to the second position to tightly fit with the glue applying head 2. After the residual glue suction head 11 and the glue applying head 2 are tightly fitted, the controller controls the vacuum pump 13 to be turned on for a preset time to suction the residual glue on the glue applying head 2 and transport the residual glue to the residual glue recovery bottle 12 through the first connecting pipe 15, so that the cleaning and recovery of the residual glue are accurately and quickly realized in an automatic manner, and the production cost is reduced.

[0032] In an embodiment, the preset time for which the vacuum pump 13 is turned on is 15-20s. In actual operation, the length of the preset time for which the vacuum pump 13 is turned on can also be adjusted according to the cleaning and recovery state of the residual glue.

[0033] In an embodiment, a buffer bottle (not shown) is further connected between the vacuum pump 13 and the second connecting pipe 16, and the buffer bottle is connected with the vacuum pump 13 through a third connecting pipe. By arranging the buffer bottle, on the one hand, the impact and damage of the residual glue cleaning and recovery device 1 caused by the unstable airflow due to the excessively high suction speed of the vacuum pump 13 can be prevented, and on the other hand, the damage of the vacuum pump 13 caused by the glue entering the vacuum pump 13 during the vacuumization can be effectively prevented.
