Description

Technical Field

[0001] The utility model relates to the technical field of defoaming equipment, in particular to a bubble-breaking pump device. Background Art

[0002] In the printed circuit board industry, in the existing PCB board manufacturing process, a large amount of foam will be generated in the developing process of the PCB board (sodium carbonate / potassium carbonate). These foams directly affect the board manufacturing effect, and will cause the PCB board surface to stick with oil (a kind of solvent), or there is a phenomenon of foam overflow.

[0003] The usual way to eliminate foam is to add an antifoaming agent to eliminate the foam; however, the addition of the antifoaming agent is often carried out by an automatic device, and the manufacturing cost is relatively high. If manual addition is used, it requires labor cost, and the addition interval time is not easy to control; moreover, the consumption of the antifoaming agent is large, and it has a certain adverse effect on the quality of the PCB board surface. To solve the above problems, circuit factories usually use a defoaming pump, also called a bubble-breaking pump, for mechanical defoaming operation;

[0004] The pump cover and the pump body of the existing bubble-breaking pump are usually fixed by bolts. When it is necessary to disassemble the impeller in the pump body, the staff needs to remove the bolts on the pump cover one by one, which takes a long time, slows down the replacement speed of the bubble-breaking impeller in the pump body, and reduces the convenience of disassembly and assembly of the pump cover, thus reducing the maintenance speed of the bubble-breaking pump. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages that the pump cover and the pump body of the existing bubble-breaking pump are usually fixed by bolts. When it is necessary to disassemble the impeller in the pump body, the staff needs to remove the bolts on the pump cover one by one, which takes a long time, slows down the replacement speed of the bubble-breaking impeller in the pump body, reduces the convenience of disassembly and assembly of the pump cover, and reduces the maintenance speed of the bubble-breaking pump, and a bubble-breaking pump device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A bubble-breaking pump device includes a power source, a pump body fixing seat and a bubble-breaking impeller assembly. A pump body assembly is arranged outside the bubble-breaking impeller assembly. The pump body assembly includes a housing and a first through hole and a second through hole circumferentially arranged on the housing. Miniature bearings are installed in both the first through hole and the second through hole. A driving gear connected to the miniature bearing is arranged on the first through hole, and a driven gear connected to the miniature bearing is arranged on the second through hole. Connecting columns are installed at the bottoms of the driving gear and the driven gear, and threaded grooves are formed at the ends of the connecting columns. A pump cover assembly is arranged below the pump body assembly.

[0008] By adopting the above technical solution, the foam-breaking impeller assembly includes a foam-breaking impeller and a coupling connected to a power source. The power source rotates at a high speed to drive the coupling to drive the foam-breaking impeller to rotate, generating suction force to suck in the foam. Then, due to the centrifugal force of the foam-breaking impeller, the foam is hit on the inner wall of the foam-breaking cavity to form liquid outflow. When it is necessary to disassemble the foam-breaking impeller assembly, the adjusting frame can be operated to drive the driving gear to rotate, so that the driven gear and the transmission chain that are in transmission connection with the driving gear rotate synchronously. As a result, multiple connecting columns cooperate with the threaded grooves and the multiple stud bolts to perform the screwing-out operation synchronously, completing the rapid disassembly operation of the pump cover assembly and the pump body assembly, which is beneficial to improving the disassembly efficiency of the foam-breaking impeller assembly.

[0009] Further, a transmission chain is provided between the driving gear and the driven gear, a tensioning wheel is installed on the transmission chain, and multiple groups of driven gears are distributed.

[0010] Further, the driving gear, the driven gear and the transmission chain are in transmission connection. A matching cover plate is provided on the pump body assembly, and an adjusting frame connected to the end face of the driving gear is provided on the cover plate.

[0011] Further, the pump cover assembly includes a suction port, stud bolts and a baffle. The thread of the stud bolt matches the threaded groove of the connecting column.

[0012] Further, a plurality of the liquid discharge ports are provided between the stud bolt and the connecting column, and the baffle is located inside the suction port.

[0013] Further, the foam-breaking impeller assembly is installed below the pump body fixing seat and connected to the output end of the power source.

[0014] Further, the pump body fixing seat and the power source are detachably connected by a first bolt, and the pump body fixing seat and the pump body assembly are detachably connected by a second bolt.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, by operating the adjusting frame to rotate the driving gear, the driving gear cooperates with the transmission chain to drive the driven gear to synchronously transmit, so that multiple groups of connecting columns perform the screwing-out action on the corresponding stud bolts, completing the rapid disassembly operation of the pump cover assembly and the pump body assembly, which is beneficial to improving the disassembly efficiency of the foam-breaking impeller assembly; moreover, through this structural design, the opening size of the liquid discharge port can be adjusted, facilitating the adjustment of the liquid discharge amount according to the use requirements, and having high practicability.

[0017] 2. In the present utility model, during the foam-breaking operation, through the setting of the baffle, the broken foam liquid can be prevented from flowing back from the suction port, avoiding affecting the foam suction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Refer to Figures 1-4 , a bubble-breaking pump device, including a power source 1, a pump body fixing seat 2 and a bubble-breaking impeller assembly 3. A pump body assembly 4 is provided outside the bubble-breaking impeller assembly 3. The pump body assembly 4 includes an outer shell 5 and a first through hole 11 and a second through hole 14 circumferentially arranged on the outer shell 5. Miniature bearings 17 are installed in both the first through hole 11 and the second through hole 14. A driving gear 12 connected to the miniature bearing 17 is provided on the first through hole 11, and a driven gear 15 connected to the miniature bearing 17 is provided on the second through hole 14. Connecting columns 18 are installed at the bottoms of the driving gear 12 and the driven gear 15, and thread grooves 21 are formed at the ends of the connecting columns 18. A pump cover assembly 6 is provided below the pump body assembly 4.

[0026] By adopting the above technical solution, the foam-breaking impeller assembly 3 includes a foam-breaking impeller and a coupling connected to the power source 1. After the power source 1 operates at high speed to drive the coupling to drive the foam-breaking impeller to rotate, suction is generated to suck in the foam. Then, due to the centrifugal force of the foam-breaking impeller, the foam is hit on the inner wall of the foam-breaking cavity, forming a liquid that flows out. When it is necessary to disassemble the foam-breaking impeller assembly 3, the adjusting frame 16 can be operated to drive the driving gear 12 to rotate, so that the driven gear 15 and the transmission chain 13 that are in transmission connection with the driving gear 12 rotate synchronously. As a result, the multiple connecting columns 18 cooperate with the threaded grooves 21 to synchronously screw out the multiple stud bolts 19, completing the rapid disassembly operation of the pump cover assembly 6 and the pump body assembly 4, which is beneficial to improving the disassembly efficiency of the foam-breaking impeller assembly 3.

[0027] A transmission chain 13 is provided between the driving gear 12 and the driven gear 15, and a tensioning wheel 22 is installed on the transmission chain 13. The driven gears 15 are distributed in several groups.

[0028] Through the action of the tensioning wheel 22, the transmission chain 13 can effectively transmit power in cooperation with the driving gear 12 and the driven gear 15, enabling the driving gear 12 and the driven gear 15 to rotate synchronously. In this way, the connecting column 18 and the stud bolt 19 cooperate to quickly complete the disassembly and installation operations of several groups of stud bolts 19 and connecting columns 18.

[0029] The driving gear 12, the driven gear 15 and the transmission chain 13 are in transmission connection. A matching cover plate 23 is provided on the pump body assembly 4, and an adjusting frame 16 connected to the end face of the driving gear 12 is provided on the cover plate 23.

[0030] The cover plate 23 provides dust-proof and protection functions for the driving gear 12, the driven gear 15, the tensioning wheel 22 and the transmission chain 13, preventing chips from accumulating on the transmission chain 13, the driving gear 12 and the driven gear 15 and affecting their transmission efficiency. The adjusting frame 16 and the cover plate 23 are movably connected, enabling the operation of the adjusting frame 16 to smoothly drive the driving gear 12 to rotate.

[0031] The pump cover assembly 6 includes a suction port 10, stud bolts 19 and a baffle 20. The threads of the stud bolts 19 match the threaded grooves 21 of the connecting columns 18.

[0032] The suction port 10 is used to suck in the foam, allowing the foam to enter the foam-breaking impeller assembly 3. After the centrifugal force of the foam-breaking impeller, the foam is hit on the inner wall of the foam-breaking cavity to complete the foam-breaking operation. The stud bolts 19 can be made of alloy or plastic. The present utility model does not make specific restrictions on the specifications and materials of the stud bolts 19.

[0033] A plurality of liquid discharge ports 8 are provided between the stud bolts 19 and the connecting columns 18, and the baffle 20 is located inside the suction port 10.

[0034] The liquid discharge port 8 is used to discharge the liquid formed by defoaming the foam. Through the action of the baffle 20, the defoamed liquid can be prevented from flowing back from the suction port 10, avoiding affecting the foam suction efficiency.

[0035] The defoaming impeller assembly 3 is installed below the pump body fixing seat 2 and connected to the output end of the power source 1.

[0036] The power source 1 can adopt a stepping motor or a servo motor. The present invention does not make specific restrictions on the specifications and types of the power source 1. The defoaming impeller assembly 3 is driven by the power source 1 to rotate, so that the defoaming impeller generates suction force, enabling the foam to enter from the suction port 10 and performing defoaming operations on the foam.

[0037] The pump body fixing seat 2 and the power source 1 are detachably connected by bolt 1 7, and the pump body fixing seat 2 and the pump body assembly 4 are detachably connected by bolt 2 9.

[0038] By disassembling and installing bolt 1 7, the pump body fixing seat 2 and the power source 1 can be disassembled and installed, and the power source 1 can be repaired or replaced. By disassembling and installing bolt 2 9, the pump body fixing seat 2 and the pump body assembly 4 can be quickly disassembled and installed.

[0039] In summary: Install this device on the equipment that needs defoaming. The defoaming impeller is driven by the power source 1 to rotate at a high speed in the pump body assembly 4, so that the foam enters the defoaming space from the suction port 10 on the pump cover assembly 6 for defoaming. The defoamed liquid is discharged from the liquid discharge port 8 between the pump cover assembly 6 and the pump body assembly 4. Then, when the pump cover assembly 6 needs to be disassembled, the staff operates the adjusting frame 16 to rotate the driving gear 12, so that the driven gear 15 and the transmission chain 13 that are drivingly connected to the driving gear 12 rotate synchronously, so that the multiple connecting columns 18 cooperate with the threaded grooves 21 and the multiple stud bolts 19 to synchronously screw out, completing the quick disassembly operation of the pump cover assembly 6 and the pump body assembly 4, which is beneficial to improving the disassembly efficiency of the defoaming impeller assembly 3. And, through the cooperation of the connecting column 18 and the stud bolt 19, the height of the liquid discharge port 8 can be adjusted according to the liquid discharge volume, effectively improving the foam removal efficiency and increasing the liquid discharge volume.
