[0002] At present, decorative plates are used in many places in decoration, and the decorative plates include a panel, an inner lining plate and a bottom plate. In the production process, the inner lining plate needs to be sprayed with glue by a glue spraying machine, and then bonded with the panel or the bottom plate respectively.

[0003] In the prior art, a common glue spraying machine is mainly a two-component glue spraying machine. The two-component glue spraying machine mainly comprises a rack fixedly installed on the ground, a glue spraying mechanism slidably installed on the rack, a processing table for placing a decorative plate fixedly installed on the rack, and the glue spraying mechanism is arranged above the processing table. The glue spraying mechanism is in communication with two glue tanks placed on the rack through two glue inlet pipes. In the process of glue spraying processing, an operator places a plate to be sprayed with glue on the workbench, and drives the glue spraying mechanism to pass through the plate at a constant speed through a glue spraying motor through a belt. The glue sprayed from the nozzle of the glue spraying machine can be uniformly coated on the surface of the plate. After the glue coating process is completed, the operator controls the glue spraying mechanism to stop glue discharge. After the operator replaces the plate, the glue spraying mechanism is restarted.

[0004] However, in the actual production process, the operator mainly manually closes or opens the glue spraying mechanism according to the position of the glue spraying mechanism, which is highly dependent on manual control and has low convenience, and there is room for improvement. CONTENT OF THE INVENTION

[0005] In order to improve the convenience of the operator using the glue spraying machine, the present application provides a rain curtain type two-component glue spraying machine.

[0006] The rain curtain type two-component glue spraying machine provided by the present application adopts the following technical scheme:

[0007] A rain curtain type two-component glue spraying machine comprises a rack, a processing table fixedly installed on the rack, a load support for placing a plate fixedly installed on the processing table, and the like.

[0008] A control panel is fixedly installed on the rack and used for inputting a plate length signal and a start signal.

[0009] A glue spraying mechanism is slidably installed on the rack and arranged above the load support.

[0010] A driving mechanism is installed on the rack, a signal input end is signal connected with a signal output end of the control panel, and the driving mechanism is used for driving the glue spraying mechanism to slide in different directions.

[0011] The glue spraying control module is installed on the nozzle of the glue spraying mechanism, and a signal input end is signal connected with a signal output end of the control panel, for receiving the start signal and the plate length signal and outputting a first control signal when detecting the plate and outputting a second control signal when the glue spraying length reaches the plate length.

[0012] The signal input end of the glue spraying mechanism is signal connected with the signal output end of the glue spraying control module, and the glue spraying mechanism receives the first control signal and sprays glue, and receives the second control signal and stops spraying glue.

After the driving mechanism receives the start signal, the glue spraying mechanism drives the glue spraying mechanism to pass above the plate, when the glue spraying mechanism passes above the plate, the glue spraying control module outputs the first control signal, and the glue spraying mechanism starts to spray glue. When the glue spraying mechanism completely passes the plate, the glue spraying control module outputs the second control signal, and the glue spraying mechanism stops spraying glue after receiving the second control signal. The technical effects of automatic detection of the plate and automatic start or stop of the glue spraying mechanism are realized, the convenience of the operator using the glue spraying machine to process the plate is improved, and the efficiency of using the glue spraying machine to process the plate is improved.

[0014] Preferably, a gantry is fixedly installed on the rack, and a mounting seat is slidably installed on the gantry, and the glue spraying mechanism is fixedly installed on the mounting seat.

[0017] By adopting the above technical scheme, the mounting seat, the glue spraying mechanism and the gantry are slidably connected through the cooperation of the slide rails and the slide blocks. The limiting grooves on the two sides of the slide rails and the limiting blocks in the slide grooves are matched and used, which can reduce the falling of the mounting seat from the slide rails and improve the stability of the sliding between the mounting seat and the glue spraying mechanism.

[0018] Preferably, the driving mechanism comprises a servo motor and a driving control module, a driving gear and a driven gear are rotatably installed on the gantry, a transmission tooth belt is installed on the driving gear and the driven gear, a mounting plate is fixedly installed on the mounting seat, and the mounting plate is fixedly connected with the transmission tooth belt.

[0019] The servo motor is fixedly installed on the gantry, and an end of a driving shaft of the servo motor is connected with the driving gear through a shaft coupling.

[0020] The signal input end of the driving control module is signal connected with the signal output end of the control panel, the signal output end of the driving control module is signal connected with the signal input end of the servo motor, the driving control module receives the starting signal and controls the servo motor to drive in different directions.

[0021] By using the above technical scheme, when the servo motor drives the mounting seat and the glue pouring mechanism to slide, the servo motor can drive the transmission tooth belt to move through the driving gear, and the transmission tooth belt moving can drive the mounting seat and the glue pouring mechanism to slide together; the servo motor driving in different directions can drive the transmission tooth belt, the mounting seat and the glue pouring mechanism to slide in different directions.

[0022] Preferably, the driving control module comprises:

[0023] An ultrasonic wave transmitting end is fixedly installed on the mounting plate, the signal input end is signal connected with the signal output end of the control panel, and the ultrasonic wave transmitting end is used for receiving the starting signal and transmitting ultrasonic waves;

[0024] An ultrasonic wave receiving end is fixedly installed on the gantry and oppositely arranged with the ultrasonic wave transmitting end, the signal input end is signal connected with the signal output end of the control panel, and the ultrasonic wave receiving end is used for detecting the distance between the mounting seat and outputting a first distance signal;

[0025] A first single-chip microcomputer is signal connected with the signal output ends of the control panel and the ultrasonic wave receiving end, and is used for receiving the starting signal and the first distance signal and outputting a third control signal or a fourth control signal, and outputting a fifth control signal when the change value of the first distance reaches a set value;

[0026] The signal output end of the first single-chip microcomputer is signal connected with the signal input end of the servo motor, the servo motor receives the third control signal and drives the mounting seat to drive in a direction away from the ultrasonic wave receiving end, receives the fourth control signal and drives the mounting seat to drive in a direction close to the ultrasonic wave receiving end, and receives the fifth control signal and stops driving.

[0027] By adopting the technical scheme, when the operator inputs the starting signal through the control panel, the ultrasonic wave emitted by the ultrasonic wave emitting end is received by the ultrasonic wave receiving end, the distance between the mounting seat, the glue pouring mechanism and the ultrasonic wave emitting end can be measured, if the mounting seat and the glue pouring mechanism are located at one end of the gantry close to the ultrasonic wave receiving end, the first single-chip microcomputer outputs the third control signal, and the servo motor receives the third control signal to drive the mounting seat and the glue pouring mechanism to slide away from the ultrasonic wave receiving end; if the mounting seat and the glue pouring mechanism are located at one end of the gantry away from the ultrasonic wave receiving end, the first single-chip microcomputer outputs the fourth control signal, and the servo motor receives the fourth control signal to drive the mounting seat and the glue pouring mechanism to slide towards the ultrasonic wave receiving end; in the process of the mounting seat and the glue pouring mechanism sliding towards the ultrasonic wave emitting end, the first distance measured by the ultrasonic wave distance sensor changes, when the change value of the first distance reaches the set value, the first single-chip microcomputer outputs the fifth control signal, and the servo motor receives the fifth control signal to stop driving, so that the servo motor drives the mounting seat and the glue pouring mechanism to slide between the two ends of the gantry to pass through the plate placed on the material support.

[0028] Preferably, the glue pouring control module comprises:

[0029] An infrared distance sensor is fixedly installed on the nozzle of the glue pouring mechanism, and is used for detecting the distance between the front shielding surface and outputting a second distance signal;

[0030] A comparator chip is signal-connected with the signal output end of the infrared distance sensor, and is used for receiving the second distance signal and outputting a high-level signal when the second distance is less than a set value;

[0032] By adopting the above technical solution, when the drive mechanism drives the mounting base and the glue-spraying mechanism to move directly above the board, since the board has a certain thickness, the second distance measured by the infrared ranging sensor is less than the set value. The comparator chip outputs a high-level signal, and the second microcontroller outputs a first control signal after recognizing the high-level signal. The glue-spraying mechanism automatically starts spraying after receiving the first control signal. Since the sliding speed of the servo motor driving the mounting base and the glue-spraying mechanism is uniform, and the length of the board is a known value, the spraying time is also a known value. The second microcontroller can calculate the duration of the high-level signal. When the duration of the high-level signal reaches the set time value of the glue-spraying mechanism passing through the board, it can be determined that the glue-spraying mechanism has completed the spraying process. The second microcontroller outputs a second control signal, and the spraying structure stops spraying glue after receiving the second control signal. This achieves the technical effect of accurately and automatically controlling the glue-spraying mechanism to start or stop automatically according to the preset length of the board, improving the convenience of operators using the glue-spraying machine.

[0033] Preferably, the material carrier includes a plurality of brackets fixedly installed on the surface of the processing table, and the plurality of brackets are arranged in parallel along the length direction of the processing table.

[0034] By adopting the above technical solution, the support frame can be used to easily place the sheet metal on the workbench.

[0035] In summary, the rain curtain type two-component coating machine of this application has at least one of the following beneficial technical effects:

[0036] 1. During actual production and processing, the operator places the board to be processed on the material carrier and inputs the required length of the board to be sprayed into the control panel. Then, a start signal is input through the control panel. Upon receiving the start signal, the drive mechanism drives the glue-spraying mechanism over the board. When the glue-spraying mechanism passes directly over the board, the glue-spraying control module outputs a first control signal, and the glue-spraying mechanism starts spraying glue. When the glue-spraying mechanism has completely passed the board, the glue-spraying control module outputs a second control signal, and the glue-spraying mechanism stops spraying glue upon receiving the second control signal. This achieves the technical effect of automatically detecting the board and automatically starting or stopping the glue-spraying mechanism, improving the convenience and efficiency of the glue-spraying process for operators.

[0037] 2. When the drive mechanism moves the mounting base and the glue-spraying mechanism directly above the board, because the board has a certain thickness, the second distance measured by the infrared ranging sensor is less than the set value. The comparator chip outputs a high-level signal, and the second microcontroller outputs a first control signal after recognizing the high-level signal. The glue-spraying mechanism automatically starts spraying after receiving the first control signal. Since the sliding speed of the servo motor driving the mounting base and the glue-spraying mechanism is uniform, and the length of the board is a known value, the spraying time is also a known value. The second microcontroller can calculate the duration of the high-level signal. When the duration of the high-level signal reaches the set time value for the glue-spraying mechanism to pass over the board, it can be determined that the glue-spraying mechanism has completed the spraying process. The second microcontroller outputs a second control signal, and the spraying structure stops spraying glue after receiving the second control signal. This achieves the technical effect of accurately and automatically controlling the glue-spraying mechanism to start or stop automatically according to the preset length of the board, improving the convenience of operators using the glue-spraying machine.

[0041] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0042] Example

[0043] This application discloses a rain curtain type two-component coating machine. (Refer to...) Figures 1-2 It mainly includes a frame 1, a processing table 11 fixedly installed on the frame 1, and a material carrier 16 for placing the plate fixedly installed on the processing table 11.

[0044] Reference Figure 1 and Figure 2The material support 16 includes several supports 16 fixedly installed on the table surface of the processing table 11, and the supports 16 are arranged parallel to each other along the length of the processing table 11. The supports 16 make it easy to place the sheet metal on the table surface of the processing table 11.

[0045] It also includes: a control panel 2, fixedly mounted on the frame 1, used to input the board length signal and the start signal; a glue-spreading mechanism 3, slidably mounted on the frame 1, and erected above the material carrier 16; a drive mechanism 4, mounted on the frame 1, with its signal input end connected to the signal output end of the control panel 2, used to drive the glue-spreading mechanism 3 to slide in different directions; and a glue-spreading control module, mounted on the nozzle of the glue-spreading mechanism 3, with its signal input end connected to the signal output end of the control panel 2, used to receive the start signal and the board length signal, and output a first control signal when the board is detected, and output a second control signal when the glue-spreading length reaches the board length.

[0046] The signal input terminal of the glue spraying mechanism 3 is connected to the signal output terminal of the glue spraying control module. The glue spraying mechanism 3 receives the first control signal and sprays the glue, and receives the second control signal and stops spraying the glue.

[0047] During actual production and processing, the operator places the board to be processed on the material carrier 16 and inputs the required length of the board to be sprayed into the control panel 2. Then, the operator inputs a start signal through the control panel 2. After receiving the start signal, the drive mechanism 4 drives the glue spraying mechanism 3 to pass over the board. When the glue spraying mechanism 3 passes directly over the board, the glue spraying control module outputs a first control signal, and the glue spraying mechanism 3 starts spraying glue. When the glue spraying mechanism 3 has completely passed the board, the glue spraying control module outputs a second control signal, and the glue spraying mechanism 3 stops spraying glue after receiving the second control signal. This achieves the technical effect of automatically detecting the board and automatically starting or stopping the glue spraying mechanism 3, improving the convenience of the operator in using the glue spraying machine to process the board and increasing the efficiency of using the glue spraying machine to process the board.

[0048] Reference Figure 1 and Figure 2 A gantry frame 12 is fixedly installed on the frame 1, and a mounting base 13 is slidably installed on the gantry frame 12. The glue-applying mechanism 3 is fixedly installed on the mounting base 13. Two slide rails 14 are fixedly installed on the side wall of the gantry frame 12, and two sliders 15 are fixedly installed on the side wall of the mounting base 13. Each slider 15 has a groove 151 that matches the two slide rails 14. Limiting grooves 141 are respectively opened on the side walls of the two slide rails 14, and limiting protrusions 152 are respectively provided on the opposite inner side walls of the two grooves 151. The limiting protrusions 152 are all embedded in the limiting grooves 141.

[0049] By cooperating with the slide rail 14 and the slider 15, the technical effect of sliding connection between the mounting base 13, the glue application mechanism 3 and the gantry frame 12 can be achieved. By cooperating with the limiting grooves 141 on both sides of the slide rail 14 and the limiting protrusions 152 in the slide groove 151, the occurrence of the mounting base 13 falling off the slide rail 14 can be reduced, and the sliding stability between the mounting base 13 and the glue application mechanism 3 can be improved.

[0050] Reference Figure 1 and Figure 2 The drive mechanism 4 includes a servo motor 41 and a drive control module. A drive gear 42 and a driven gear 43 are rotatably mounted on the gantry 12. A transmission toothed belt 44 is mounted on the drive gear 42 and the driven gear 43. A mounting plate is fixedly mounted on the mounting base 13 and is fixedly connected to the transmission toothed belt 44. The servo motor 41 is fixedly mounted on the gantry 12, and the drive shaft end of the servo motor 41 is connected to the drive gear 42 through a coupling.

[0051] The signal input terminal of the drive control module is connected to the signal output terminal of the control panel 2, and the signal output terminal of the drive control module is connected to the signal input terminal of the servo motor 41. The drive control module receives the start signal and controls the servo motor 41 to drive in different directions.

[0052] When the servo motor 41 drives the mounting base 13 to slide with the glue coating mechanism 3, the servo motor 41 can drive the transmission belt 44 to move through the drive gear 42. The movement of the transmission belt 44 can drive the mounting base 13 and the glue coating mechanism 3 to slide together. The servo motor 41 can drive the transmission belt 44, the mounting base 13 and the glue coating mechanism 3 to slide in different directions.

[0053] Reference Figure 1 and Figure 2 The drive control module includes: an ultrasonic transmitter 45, fixedly mounted on the mounting plate, with its signal input terminal connected to the signal output terminal of the control panel 2, for receiving a start signal and transmitting ultrasonic waves; an ultrasonic receiver 46, fixedly mounted on the gantry 12, positioned opposite to the ultrasonic transmitter 45, with its signal input terminal connected to the signal output terminal of the control panel 2, for detecting the distance between the receiver and the mounting base 13 and outputting a first distance signal; and a first microcontroller, with its signal input terminal connected to the signal output terminals of the control panel 2 and the ultrasonic receiver 46, for receiving the start signal and the first distance signal and outputting a third or fourth control signal, and outputting a fifth control signal when the change value of the first distance reaches a set value.

[0054] The signal output terminal of the first microcontroller is connected to the signal input terminal of the servo motor 41. The servo motor 41 receives the third control signal and drives the mounting base 13 to move away from the ultrasonic receiver 46, receives the fourth control signal and drives the mounting base 13 to move closer to the ultrasonic receiver 46, and receives the fifth control signal and stops driving.

[0055] When the operator inputs a start signal through control panel 2, the ultrasonic waves emitted by ultrasonic transmitter 45 are received by ultrasonic receiver 46. The distance between mounting base 13, glue application mechanism 3, and ultrasonic transmitter 45 can be calculated. If mounting base 13 and glue application mechanism 3 are located on the gantry frame 12 near the ultrasonic receiver 46, the first microcontroller outputs a third control signal. The servo motor 41 receives the third control signal and drives mounting base 13 and glue application mechanism 3 to slide away from the ultrasonic receiver 46. If mounting base 13 and glue application mechanism 3 are located on the gantry frame 12 away from the ultrasonic receiver 46, the first microcontroller outputs a third control signal. The fourth control signal is issued. After receiving the fourth control signal, the servo motor 41 drives the mounting base 13 and the glue coating mechanism 3 to slide towards the ultrasonic receiver 46. During the interaction between the mounting base 13 and the glue coating mechanism 3 towards or away from the ultrasonic transmitter 45, the first distance measured by the ultrasonic ranging sensor changes. When the change value of the first distance reaches the set value, the first microcontroller outputs the fifth control signal. After receiving the fifth control signal, the servo motor 41 stops driving, which allows the servo motor 41 to drive the mounting base 13 and the glue coating mechanism 3 to slide between the two ends of the gantry 12 to pass over the plate placed on the material carrier 16.

[0056] Reference Figure 1 and Figure 2 Figure 1 Figure 2 The glue application control module includes: an infrared distance sensor 5, fixedly mounted on the nozzle of the glue application mechanism 3, used to detect the distance between itself and the obstructing surface in front and output a second distance signal; a comparator chip, whose signal input terminal is connected to the signal output terminal of the infrared distance sensor 5, used to receive the second distance signal and output a high-level signal when the second distance is less than a set value; and a second microcontroller, whose signal input terminal is connected to the signal output terminal of the comparator chip and the control panel 2, used to receive the high-level signal and output a first control signal and a board length signal, and output a second control signal when the duration of the high-level signal reaches a set duration.

[0057] When the drive mechanism 4 drives the mounting base 13 and the glue-spraying mechanism 3 to move directly above the board, since the board has a certain thickness, the second distance measured by the infrared distance sensor 5 is less than the set value. The comparator chip outputs a high-level signal, and the second microcontroller outputs a first control signal after recognizing the high-level signal. The glue-spraying mechanism 3 automatically starts spraying after receiving the first control signal. Since the sliding speed of the servo motor 41 driving the mounting base 13 and the glue-spraying mechanism 3 is uniform, and the length of the board is a known value, the spraying time is a known value. The second microcontroller can calculate the duration of the high-level signal. When the duration of the high-level signal reaches the set time value of the glue-spraying mechanism 3 passing through the board, it can be determined that the glue-spraying mechanism 3 has completed the spraying process. The second microcontroller outputs a second control signal, and the spraying structure stops spraying glue after receiving the second control signal. This can achieve the technical effect of accurately and automatically controlling the glue-spraying mechanism 3 to start or stop automatically according to the preset length of the board, improving the convenience of operators using the glue-spraying machine.

[0058] The implementation principle of a rain curtain type two-component glue coating machine according to an embodiment of this application is as follows: During the actual production process, the operator places the board to be processed on the material carrier 16 and inputs the length of the board to be sprayed into the control panel 2. Then, the operator inputs a start signal through the control panel 2. After receiving the start signal, the drive mechanism 4 drives the glue coating mechanism 3 to pass over the board. When the glue coating mechanism 3 passes directly over the board, the glue coating control module outputs a first control signal, and the glue coating mechanism 3 starts spraying glue. When the glue coating mechanism 3 has completely passed the board, the glue coating control module outputs a second control signal, and the glue coating mechanism 3 stops spraying glue after receiving the second control signal. This achieves the technical effect of automatically detecting the board and automatically starting or stopping the glue coating mechanism 3, improving the convenience of the operator in using the glue coating machine to process the board and improving the efficiency of using the glue coating machine to process the board.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
