[0059] The following is combined with Figure 1-8 The technical solution of the present invention is further illustrated by specific implementation methods.

[0060] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0061] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, which can be said to be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] A glue dispensing machine for AB glue, comprising a mounting plate 1, a control console 2, a glue conveying mechanism 3, a glue supply device 4 and a glue mixing tube 5;

[0063] The glue delivery mechanism 3 and the control console 2 are installed adjacent to each other on the mounting plate 1 in front and back;

[0064] The glue delivery mechanism 3 includes a base plate 31 and two glue delivery units 32; the glue delivery unit 32 includes a glue storage cylinder 321, a gear pump 326, a glue delivery plate 328 and a glue back-suction valve 324;

[0065] The base plate 31 is rotatably mounted on the top surface of the console 2; the two glue delivery plates 328 are adjacently mounted on the top surface of the base plate 31; the gear pump 326 and the cylinder body 3211 are respectively mounted on the top surfaces of the glue delivery plates 328;

[0066] The glue storage cylinder 321 includes a cylinder body 3211 and a glue discharging piston 3212; a storage chamber 32110 is provided in the cylinder body 3211, and the storage chamber 32110 is used to store glue A or glue B; a glue delivery channel 3280 is provided in the glue delivery plate 328; the bottom of the storage chamber 32110 is connected to the middle of the glue delivery channel 3280, and the glue discharging piston 3212 is installed above the cylinder body 3211, and the output end of the glue discharging piston 3212 extends into the storage chamber 32110 from the top;

[0067] One end of the glue delivery channel 3280 is connected to the glue supply device 4 to input glue A or glue B; the gear pump 326 is provided with an adjacent and connected suction chamber and a discharge chamber, and the suction chamber and the discharge chamber are both equipped with gears; the two gears are meshed with each other, the input port of the suction chamber is connected to the other end of the glue delivery channel 3280, and the output port of the discharge chamber is connected to the input port of the glue back-suction valve 324 and outputs glue A or glue B to the glue back-suction valve 324.

[0068] Figure 1 The structure diagram of an embodiment of a dispensing machine for AB glue of the present invention is shown in FIG. Figure 2The two glue delivery units 32 shown in the figure are adjacently arranged above the base plate 31, and the mixed glue A and glue B can be output outward through the output port at the lower end of the glue mixing pipe 5 and applied to the bonding position of the workpiece.

[0069] like Figure 2 and Figure 3 As shown, in a glue dispensing machine for AB glue of the present invention, glue A or glue B in the storage chamber 32110 of the glue storage cylinder 321 enters the glue delivery channel 3280 from the middle under the action of the glue discharge piston 3212, and then flows into the corresponding suction chamber of the gear pump 326. The glue A or glue B entering the suction chamber is squeezed by two gears meshing with each other, and is delivered from the output port of the discharge chamber to the input port of the glue return valve 324, and then the glue A and glue B are mixed in the glue mixing tube 5; since the volumes of the suction chamber and the discharge chamber of the gear pump 326 are unchanged, the glue output of the gear pump 326 is linearly related to the rotation speed of the gear pump 326, so by controlling the rotation speed of the gear pump 326, the output of glue A or glue B per unit time of the glue delivery channel 3280 can be controlled, and then the ratio of glue A and glue B can be controlled.

[0070] By controlling the start and stop of the gear pump 326, the opening and closing of the other end of the glue delivery channel 3280 can also be controlled; when the remaining amount of glue in the glue storage cylinder 321 is small and glue needs to be replenished, the two gear pumps 326 and the two glue discharge pistons 3212 can be shut down, and at the same time, the glue supply device 4 is started, and glue A or glue B is input into the corresponding glue storage cylinder 321.

[0071] Furthermore, the glue delivery unit 32 also includes a temperature controller 322 and an air pressure regulator 323;

[0072] The outer periphery of the cylinder body 3211 is covered with an electric heating sleeve 32111; the temperature controller 322 is mounted above the glue conveying plate 328; the electric heating sleeve 32111 is electrically connected to the temperature controller 322;

[0073] The air pressure regulator 323 is mounted above the glue conveying plate 328 ; the glue discharging piston 3212 is driven by a power air source, and the air pressure regulator 323 is used to control the output air pressure of the power air source.

[0074] like Figure 3 and Figure 4As shown, the outer periphery of the cylinder body 3211 is covered with an electric heating sleeve 32111, which can heat the glue A or glue B stored in the storage chamber 32110 of the glue storage cylinder 321, and the heating temperature of the electric heating sleeve 32111 can be controlled by the temperature controller 322, so that the glue A and glue B located in the two storage chambers 32110 have a more suitable temperature and viscosity, thereby enabling the glue A and glue B to obtain a more suitable fluidity.

[0075] The output air pressure of the power air source that drives the glue discharging piston 3212 is controlled by the air pressure regulator 323, and the output air pressure is kept constant, so that the glue A and glue B in the two storage chambers 32110 are in a constant temperature and pressure state, which can further improve the viscosity stability of the output glue A or glue B and prevent the glue in the glue delivery channel 3280 from being interrupted and generating bubbles.

[0076] Furthermore, the glue delivery unit 32 also includes a high-pressure air valve 325 and a solenoid valve 327;

[0077] The solenoid valve 327 is disposed close to the corresponding glue storage cylinder 321, and the solenoid valve 327 is used to control the on-off of the delivery pipeline of the power gas source;

[0078] The high-pressure air valve 325 is installed close to the end of the glue delivery plate 328 away from the glue back-sucking valve 324;

[0079] The output end of the high-pressure air valve 325 is connected to one end of the glue delivery channel 3280 , and the input end of the high-pressure air valve 325 is connected to the glue supply device 4 to input glue A or glue B.

[0080] like Figure 3 and Figure 4 As shown, the solenoid valve 327 is used to control the on / off of the delivery pipeline of the power air source that drives the glue discharging piston 3212, so that the glue storage cylinder 321 is in a pressure maintaining state or a pressure relief state, and then the glue delivery channel 3280 outputs glue, or the glue storage cylinder 321 obtains glue replenishment.

[0081] like Figure 3 and Figure 4 As shown, the opening and closing of one end of the glue delivery channel 3280 can be controlled by the high-pressure air valve 325; when the glue delivery channel 3280 delivers glue A or glue B to the glue suction valve 324, the corresponding high-pressure air valve 325 is closed; when the remaining amount of glue in the glue storage cylinder 321 is lower than the limit position and glue needs to be replenished, the gear pump 326 stops and the corresponding high-pressure air valve 325 is opened, and the glue supply device 4 can input glue A or glue B to the glue storage cylinder 321 through the high-pressure air valve 325.

[0082] Furthermore, the glue storage cylinder 321 also includes a cover 3214, a sensor 3215 and a trigger rod 3216;

[0083] The glue discharging piston 3212 includes an upper piston rod 32121 and a lower piston rod 32122;

[0084] The cover body 3214 is vertically installed above the cylinder body 3211; the lower end of the lower piston rod 32122 extends downward and extends into the storage chamber 32110, the upper end of the lower piston rod 32122 is connected to the lower end of the upper piston rod 32121, and the upper end of the upper piston rod 32121 extends upward and extends into the cover body 3214;

[0085] The sensor 3215 is installed on the top surface of the upper piston rod 32121; the trigger rod 3216 is installed on the side of the upper piston rod 32121 and close to the upper end of the upper piston rod 32121, the upper end of the trigger rod 3216 is connected to the sensor 3215, and the lower end of the trigger rod 3216 is a free end;

[0086] The sensor 3215 is signal-connected to the gear pump 326 , the solenoid valve 327 and the high-pressure gas valve 325 , respectively.

[0087] like Figure 3 and Figure 4 The glue storage cylinder 321 shown is a double-discharging-shaft cylinder, wherein the glue discharging piston 3212 includes an upper piston rod 32121 and a lower piston rod 32122 which can move up and down synchronously.

[0088] When the upper piston rod 32121 is pressed down and glue A or glue B is delivered to the glue back-suction valve 324 through the glue delivery channel 3280, the corresponding high-pressure air valve 325 is in a closed state and the gear pump 326 is in an operating state. Then, when the glue liquid level in the cylinder body 3211 drops and reaches a limited position, the lower end of the upper piston rod 32121 is close to the top surface of the cylinder body 3211, and the lower end of the trigger rod 3216 contacts and is subjected to force on the top surface of the cylinder body 3211. The trigger rod 3216 triggers the sensor 3215. The triggered sensor 3215 simultaneously sends signals to the gear pump 326, the solenoid valve 327 and the high-pressure air valve 325 respectively. The gear pump 326 is closed, the high-pressure air valve 325 is opened, and the solenoid valve 327 disconnects the pipeline for delivering the power air source, and the glue storage cylinder 321 is depressurized. Subsequently, the glue supply device is started and glue A or glue B is input into the glue storage cylinder 321 through the high-pressure air valve 325.

[0089] Afterwards, as the glue in the cylinder 3211 is replenished, the glue discharging piston 3212 is pushed up by the replenished glue. When the upper end of the upper piston rod 32121 is close to the top of the cover body 3214 and the sensor 3215 contacts and triggers the top of the cover body 3214, the sensor 3215 simultaneously sends signals to the gear pump 326, the solenoid valve 327 and the high-pressure air valve 325 respectively. The high-pressure air valve 325 is closed, and the solenoid valve 327 makes the air pipe of the power air source that drives the glue discharging piston 3212 open, and pressurizes the glue storage cylinder 321 to the set pressure value. Then the gear pump 326 starts and delivers glue A or glue B to the glue suction valve 324.

[0090] In some embodiments, the glue storage cylinder 321 further includes an indicator sheet 3213 , the cover body 3214 is made of a transparent material, and scale lines are provided on the circumference of the cover body 3214 ; the indicator sheet 3213 is installed between the sensor 3215 and the top surface of the upper piston rod 32121 .

[0091] like Figure 3 and Figure 4 As shown, by observing the position of the indicator sheet 3213 and the corresponding scale line, the remaining amount of glue in the cylinder body 3211 can be indirectly known.

[0092] In some embodiments, the indicator sheet 3213 is red or orange-yellow. The indicator sheet 3213 is red or orange-yellow, which can improve the recognition of the indicator sheet 3213 and the convenience of reading the corresponding scale.

[0093] Furthermore, the glue supply device 4 includes a lifting assembly 42, a mounting frame 43, two glue pumps 44 and two glue buckets 41;

[0094] The mounting frame 43 includes a mounting plate 431 and a connecting frame 432;

[0095] The bottom surface of the lifting assembly 42 is fixed to the mounting plate 1, and the output end of the lifting assembly 42 is arranged upward; the upper end of the connecting frame 432 is connected to the output end of the lifting assembly 42, and the lower end of the connecting frame 432 is connected to the mounting plate 431;

[0096] The two glue barrels 41 are placed on the mounting plate 1 at intervals on the left and right, and are located below the mounting plate 431;

[0097] The two glue pumps 44 are inserted into the mounting plate 431 at intervals on the left and right. The input end of the glue pump 44 passes downward through the mounting plate 431 and extends into the bottom of the corresponding glue bucket 41. The output end of the glue pump 44 is connected to the input end of the corresponding high-pressure air valve 325.

[0098] Figure 6 and Figure 7It is a schematic structural diagram of an embodiment of the glue supply device 4 of the present invention, and two glue buckets 41 are used to contain glue A and glue B respectively.

[0099] When the remaining amount of glue in the glue bucket 41 reaches a limited value and the two glue buckets 41 need to be replaced, the lifting assembly 42 can be started, and the lifting assembly 42 can drive the mounting plate 32 and the two glue pumps 44 to rise synchronously through the connecting frame 432. After the two glue pumps 44 are raised to above the two glue buckets 41, the two glue buckets 41 can be taken out from under the mounting plate 431, and the two glue buckets 41 filled with glue can be replaced. Then, the lifting assembly 42 is turned off and the mounting plate 32 and the two glue pumps 44 are synchronously driven to reset, and the operation of the two glue buckets 41 can be completed.

[0100] like Figure 6 In the illustrated embodiment, the output end of the glue pump 44 can be connected to the input end of the high-pressure air valve 325 by connecting the pipe 47, the first glue pipe and the second glue pipe to improve the convenience of disassembly and assembly.

[0101] Furthermore, the glue supply device 4 also includes two liquid level detectors 45;

[0102] The two liquid level detectors 45 are inserted into the mounting plate 431 at intervals on the left and right, and the bottom ends of the liquid level detectors 45 pass downward through the mounting plate 431 and extend into the bottom of the corresponding glue bucket 41 .

[0103] like Figure 7 As shown, the liquid level detector 45 can detect whether the glue liquid level in the glue bucket 41 is lower than the limit position. When the glue liquid level is lower than the limit position, it means that the remaining amount of glue reaches the limit value, that is, the corresponding glue bucket 41 needs to be replaced.

[0104] Further, the lifting assembly 42 includes a mounting base 426, a lifting cylinder 421 and a connecting plate 424;

[0105] The bottom surface of the mounting base 426 is used to be fixed to the AB glue dispensing machine, the lower end of the lifting cylinder 421 is mounted on the mounting base 426, and the output end of the lifting cylinder 421 is arranged upward;

[0106] The bottom surface of the connecting plate 424 is connected to the output end of the lifting cylinder 421 , and the top surface of the connecting plate 424 is in contact with the upper end of the connecting frame 432 .

[0107] like Figure 7 and Figure 8 As shown, by the abutment between the connecting plate 424 and the connecting frame 432 , the force bearing area of ​​the connecting frame 432 can be expanded, and the lifting and lowering stability of the connecting frame 432 can be improved.

[0108] Furthermore, the lifting assembly 42 also includes a guide seat 425, a support plate 428, two guide columns 422 and a plurality of support columns 427;

[0109] A plurality of support columns 427 are vertically arranged around the lifting cylinder 421, the lower ends of the support columns 427 are connected to the mounting base 2, the upper ends of the support columns 427 are connected to the support plate 428, and the guide seat 425 is mounted above the support plate 428; the output end of the lifting cylinder 421 passes through the support plate 428 and the guide seat 425 in sequence upward, and then is connected to the bottom surface of the connecting plate 424;

[0110] The two guide posts 422 are spaced apart from each other, the upper ends of the guide posts 422 are connected to the connecting plate 424 , and the lower ends of the guide posts 422 pass through the guide seat 425 and extend downward.

[0111] like Figure 7 and Figure 8 As shown, the guiding effect of the connecting plate 424 connected to the two guide posts 422 can prevent the lifting cylinder 421 from shaking left and right during the lifting process, thereby improving the lifting stability of the lifting cylinder 421 and the mounting frame 43.

[0112] Furthermore, the glue supply device 4 also includes a cylinder control valve 46;
