Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, and in particular to a dispensing machine for circuit board processing. Background Technology

[0002] Dispensing is a process, also known as gluing, coating, potting, and dripping, in which electronic adhesives, oils, or other liquids are applied, potted, or dripped onto a product to achieve functions such as adhesion, potting, insulation, fixation, and surface smoothing.

[0003] The existing patent publication number is CN221288478U, which discloses a dispensing machine for circuit board processing. This utility model uses a dispensing table, slot, pressure plate, top rod, support and insert plate in cooperation. After the dispensing is completed, the slide table retracts. At this time, the insert plate on one side of the top of the support will be inserted into the slot, and then the pressure plate will be pushed up. After the pressure plate is pushed up, it will drive the top rod to lift one side of the circuit board held in the dispensing table, which makes disassembly faster and more convenient.

[0004] However, the dispensing machine for circuit board processing disclosed in the above patent requires the dispensing machine to be turned off and the circuit board replaced after dispensing is completed. This is inconvenient, time-consuming, and labor-intensive, reducing processing efficiency. Therefore, we propose a dispensing machine for circuit board processing to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 An embodiment of this utility model provides a dispensing machine for circuit board processing, including a lifting block 4, a column 9 fixedly mounted on the top of the lifting block 4, a processing table 5 fixedly mounted on the front end of the lifting block 4, a slide groove 6 fixedly opened in the middle of the processing table 5, a slide rod 7 slidably mounted inside the slide groove 6, the slide groove 6 passing through the left and right sides of the processing table 5, a placement plate 8 fixedly mounted on the top of the slide rod 7, the lower surface of the placement plate 8 movably fitting against the upper surface of the processing table 5, a rack 12 fixedly mounted on the rear end of the top of the placement plate 8, a motor 10 fixedly mounted on the rear side of the column 9, a gear 11 rotatably mounted on the front side of the column 9, the drive end of the motor 10 movably passing through the front side of the column 9 and fixedly connected to the gear 11, the gear 11 and the rack 12 meshing with each other, and two limiting frames 20 fixedly mounted on the upper surface of the placement plate 8, the two limiting frames 20 being symmetrically distributed about the center line of the placement plate 8.

[0031] Furthermore, a dispensing assembly is provided on the top of the column 9. The dispensing assembly includes a horizontal column 15, which is fixedly installed on the top of the column 9. A second motor 16 is fixedly installed at the rear end of the horizontal column 15. A movable groove is fixedly opened inside the horizontal column 15. A screw 17 is rotatably installed inside the movable groove. The drive end of the second motor 16 extends into one end of the movable groove and is fixedly connected to the screw 17. A movable block is threadedly connected to the outer ring of the screw 17. An electric push rod 18 is fixedly installed at the bottom of the movable block. A dispensing machine body 19 is installed at the telescopic end of the electric push rod 18.

[0032] In use, this invention places two circuit boards to be processed on two limiting frames 20 respectively. The electric push rod 18 is activated, causing the dispensing machine body 19 to move downwards, dispensing one circuit board. After processing the circuit board, the motor 10 is activated, driving the gear 11 to rotate, which in turn moves the rack 12, the placement plate 8, and the limiting frame 20 onto the processing table 5, thereby moving the other circuit board to the processing position on the dispensing machine body 19. This allows for rapid replacement of the circuit board. The processed circuit board is then removed, and a new circuit board is placed on top. This process is repeated, solving the problem that existing dispensing machines for circuit board processing require shutting down the dispensing machine body 19 to replace the circuit board after dispensing, which is inconvenient, time-consuming, labor-intensive, and reduces processing efficiency.

[0033] When different positions on the circuit board need to be processed, the second motor 16 is started, which drives the screw 17 to rotate, thereby causing the movable block, electric push rod 18 and dispensing machine body 19 to move on the horizontal column 15, thereby adjusting the position of the dispensing machine body 19. In addition, after starting the first motor 10, the limit frame 20 is moved. In this way, the dispensing machine body 19 can process different positions on the circuit board, improving the practicality of the device.

[0034] To reduce the harm of adhesive dispensing odors to employees, a filter assembly is installed on the column 9. The filter assembly includes an air hood 13 and a filter 14. The filter 14 is fixedly installed on the rear side of the column 9, and the air hood 13 is fixedly installed on the front side of the column 9. An air inlet is fixedly opened inside the column 9. The air hood 13, the air inlet, and the filter 14 are interconnected. The air hood 13 is located above the gear 11. During the operation of the dispensing machine body 19, the filter 14 is activated to draw outside air into the air hood 13 and the air inlet. After being filtered by the filter 14, the air is discharged to the outside, thereby preventing the adhesive dispensing odors from spreading and effectively reducing the harm of adhesive dispensing odors to employees.

[0035] Considering the different heights of employees, a lifting assembly is installed on the lifting block 4. The lifting assembly includes a base plate 1, with two guide rails 2 fixedly installed on the top of the base plate 1. The lifting block 4 is slidably positioned between the two guide rails 2. A hydraulic cylinder 3 is fixed on the base plate 1 between the two guide rails 2. The telescopic end of the hydraulic cylinder 3 is fixedly connected to the bottom of the lifting block 4. The left and right sides of the column 9 are respectively in contact with the two guide rails 2. When it is necessary to adjust the height of the processing table 5, the hydraulic cylinder 3 is activated, which drives the lifting block 4 to move between the two guide rails 2, thereby adjusting the height of the processing table 5. This makes it easier for people of different heights to operate on the processing table 5 and improves the flexibility of the device.

[0036] Furthermore, it also includes a controller. The hydraulic cylinder 3, motor 10, filter 14, motor 2 16 and dispensing machine body 19 are all electrically connected to the controller. The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] Working principle: When using this utility model, two circuit boards to be processed are placed on two limiting frames 20 respectively. The electric push rod 18 is started, which drives the dispensing machine body 19 to move downward to dispense glue to one of the circuit boards. After the processing of the circuit board is completed, the motor 10 is started, which drives the gear 11 to rotate, thereby driving the rack 12, the placement plate 8 and the limiting frame 20 to move on the processing table 5, thereby moving the other circuit board to the processing position of the dispensing machine body 19, thus realizing the rapid replacement of the circuit board. The processed circuit board is then removed and a new circuit board is placed on it, and this process is repeated.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
