[0024] Reference Figures 1 to 3 As shown, an embodiment of a dispensing device for a circuit board workbench of the present invention comprises a workbench 1, a bracket 2 is arranged on the workbench 1, a longitudinal moving component is arranged on the top of the bracket 2, a mounting plate 3 is arranged on the longitudinal moving device, and a lifting and moving dispensing component 4 is arranged on the mounting plate 3; a bottom plate 5 is arranged at the bottom of the longitudinal moving component on the workbench 1, an auxiliary moving device 6 is arranged on the bottom plate 5, a moving frame 7 is arranged on the auxiliary moving device 6, vertical frames 8 are arranged on both sides of the auxiliary moving device 6, a moving track 9 is arranged between the vertical frames 8, a glue head placement plate 10 is arranged in the moving track 9, a driving device 11 is arranged on one side of the moving track 9, a main lifting cylinder 12 is arranged on the moving frame 7, a limiting lifting plate 13 is arranged on the output end of the main lifting cylinder 12 through a connecting plate, and the limiting lifting plate 13 is arranged in the moving track 9, and a guide limiting plate 14 is arranged on both sides of the moving track 9 on the top of the moving frame 7, and a carrier moving component is arranged on the workbench 1.

[0025] When in use, place the bottom plate 5 carrying the circuit board to be processed on the carrier moving assembly to adjust the position, then start the top longitudinal moving assembly to adjust the position of the mounting plate 3, then adjust the lifting and moving dispensing assembly 4 to change the position of the dispensing head so that it can be aligned with the position to be processed for processing. After the processing is completed, continue to use the longitudinal moving assembly and the lifting and moving dispensing assembly 4 to change the position of the dispensing head so that it enters the side glue head placement plate 10 for protection to prevent it from being damaged. The replacement and fixing process of the glue head placement plate 10 is as follows: Starting the auxiliary moving device 6 on one side can drive the moving frame 7 to move along the direction of the moving track 9 and stop when it moves to the preset position. At this time, a glue head placement plate 10 is added to the end of the moving track 9, and the driving device 11 on the side is started to drive the glue head placement plate 10 to move along the moving track 9. Then the main lifting cylinder 12 is started to drive the limiting lifting plate 13 to rise until it partially protrudes from the moving track 9. At this time, the glue head placement plate 10 continues to move forward until it encounters the limiting lifting plate 13 and cannot move. At this time, the driving device 11 is stopped, and the guide limiting plates 14 on both sides facilitate the glue head placement plate 10 to enter the preset position, that is, the top of the moving frame 7.

[0026] An auxiliary lifting cylinder 15 is arranged on the other side of the movable frame 7, and the output end of the auxiliary lifting cylinder 15 is also connected to the limit lifting plate 13. If there is a problem with the main lifting cylinder 12, the auxiliary lifting cylinder 15 can also drive the limit lifting plate 13 to move upward to complete the limit operation.

[0027] The longitudinal moving component includes two transverse plates 16 arranged on the top of the bracket 2, and the transverse plates 16 are each provided with a first shift rail 17. Two pulley seats 18 are arranged on both sides of the first shift rail 17, and a driving wheel 19 and a driven wheel 20 are respectively arranged. A transmission belt 44 is arranged between the driving wheel 19 and the driven wheel 20, and a synchronous shaft 22 is arranged between the two driving wheels 19. One of the driving wheels 19 is connected to a first motor 23, and a moving plate 24 adapted to the transmission belt 44 is arranged on the first shift rail 17. The mounting plate 3 is arranged on the moving plate 24. The first motor 23 is started to drive the driving wheel 19 to rotate. The driving wheel 19 rotates and drives the transmission belts 44 on both sides to move synchronously through the cooperation with the driven wheel 20 and the synchronous shaft 22, so as to drive the moving plate 24 to move forward and backward.

[0028] The lifting and moving dispensing assembly 4 includes a second shift rail 41 and a second motor 42 arranged on the mounting plate 3, a transmission wheel 43 is arranged on the output end of the second motor 42 and the mounting plate 3, and a transmission belt 44 is also arranged between the transmission wheels 43, a lifting plate 45 used in conjunction with the transmission belt 44 is arranged on the second shift rail 41, and an upper plate 46 and a lower plate 47 are arranged on the lifting plate 45, a transfer seat 48 is arranged on the top of the mounting plate 3, a feeding pipe 49 is arranged between the dispensing head and the transfer seat 48, and a feeding channel 410 is arranged on the other side of the transfer seat 48, The feed pipe 49 passes through the adapter 48, and a buffer spring 411 is arranged between the upper plate 46 and the lower plate 47 on the circumferential side of the feed pipe 49. The dispensing heads are evenly spaced on the lower plate 47. The second motor 42 is started to drive the transmission belt 44 to move through the transmission effect of the transmission wheel 43, thereby driving the lifting plate 45 to move up and down to adjust the position of the dispensing head. The loading channel 410 is connected to an external feeding device to provide colloid. It is inevitable to encounter resistance during the placement or dispensing process of the dispensing head. At this time, the buffer spring 411 can shrink as the feed pipe 49 moves to absorb the buffer force and prevent it from causing damage.

[0029] A limit sensor 25 is arranged on the top of the bracket 2, which can monitor the position of the top movable plate 24 in real time and play a certain limit effect.

[0030] A material blocking cylinder 26 is provided on one of the vertical frames 8, and a material blocking plate 27 is provided at the output end of the material blocking cylinder 26. The material blocking plate 27 is arranged between the two moving rails 9. After there is a glue head placement plate 10 between the two moving rails 9, the material blocking cylinder 26 is started to drive the material blocking plate 27 to rise and block the position between the two moving rails 9 to prevent repeated loading.

[0031] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention.
