Description
Technical Field
[0001] The invention relates to the technical field of circuit board dispensing, and more specifically to an efficient dispensing device for SMT patches. Background Art
[0002] SMT placement machine is a machine that processes a series of processes based on PCB printed circuit boards. SMT is surface mount technology (surface mount technology), which is the most popular technology and process in the electronic assembly industry. At the same time, the placement machine is a combination of mechanical, electrical, optical and computer control technology. It can quickly and accurately mount SMD components to the pad positions specified by the PCB board through functions such as absorption, displacement, positioning and placement. In the manufacturing process of electronic products, dispensing technology is usually required to achieve bonding between two workpieces.
[0003] Among them, the patent with publication number CN221768636U discloses a dispensing device for SMT patches, including a base, a workbench is provided above the base, and a clamping groove is provided on the top of the workbench, a sealing plate is fixedly connected to the top of the workbench, a clamping mechanism is provided on the top of the sealing plate, a second electric slide rail is fixedly connected to the top of the sealing plate near the left and right sides, the inner cavities of the two second electric slide rails are slidably connected to the first electric slider near the rear side, the tops of the two first electric sliders are fixedly connected to the sliding plate, and the front side of the sliding plate is fixedly connected to the first electric slide rail near the top; When this structure is in use, the workpiece can be clamped and fixed through the mutual cooperation between the clamping plate, the first rack plate, the worm wheel, the second rack plate, the worm, the first servo motor and the movable gear, thereby improving the stability during dispensing, improving the efficiency of use, and facilitating the height adjustment of the dispensing barrel, which facilitates the dispensing work. However, when dispensing, this structure can easily cause the glue to accumulate together, which can easily cause uneven dispensing, resulting in poor dispensing effect and subsequent loose bonding between the two workpieces. Summary of the invention
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an efficient SMT patch dispensing device, aiming to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an efficient SMT patch dispensing device, comprising a base, on which a dispensing component is arranged.
[0006] The dispensing assembly includes a protective box arranged on the top of the base. One side of the protective box is provided with a support frame. One side of the support frame is provided with a top plate located on the top of the base. The bottom of the support frame is provided with two first electric push rods, and the output ends of each of the first electric push rods are fixed on one side of the support frame. The other end of the first electric push rod is arranged at the bottom of the top plate. Connecting frames are arranged on both sides of the dispenser, and the connecting frames are installed on the protective box through bolts. The top plate is slidably connected to the support frame, and the top plate is slidably connected to the base.
[0007] It can be seen that in the above technical solution, when dispensing the circuit board, it is placed on the dispensing table. The screw hole block is driven by the screw drive module to drive various structures on the top plate and the support frame to adjust the position on the base, so that the dispensing table can approach the protective cover. The vibration motor and the elastic abutting block are driven to displace by the third electric push rod, so that the elastic abutting block can abut against the workpiece. The amplitude generated by the start of the vibration motor is transmitted to the elastic abutting block, so that the glue liquid can be quickly flattened and dispersed due to the workpiece being affected by the amplitude, making the subsequent bonding of the two workpieces more firm.
[0008] A dispenser is arranged inside the protective box. A pump for pressurization is arranged on the dispenser. One end of the dispenser is provided with a delivery conduit. One end of the delivery conduit is provided with a protective cover. A dispensing head communicated with the delivery conduit is arranged inside the protective cover. An inclined plate is arranged on the top of the top plate. Two third electric push rods are arranged on the inclined plate. The output ends of the two third electric push rods are both provided with vibration motors, and elastic abutting blocks are arranged on each of the vibration motors. A second electric push rod for driving the displacement of the delivery conduit is arranged on one side of the delivery conduit, and the second electric push rod is installed on the dispenser.
[0009] A screw hole block is arranged at the bottom of the top plate. A screw drive module for driving the displacement of the screw hole block is arranged on the screw hole block. The screw drive module is installed at the bottom of the base through bolts. First belt pulleys are arranged on both sides of the screw hole block, and a second belt pulley is fixedly arranged at the bottom of one of the first belt pulleys. A drive motor is installed at one side of the bottom of the screw hole block through bolts. The drive motor is connected to the second belt pulley and the two first belt pulleys through belt drives. Dispensing tables are fixedly arranged on the two first belt pulleys, and each of the dispensing tables penetrates through the top plate and extends to the bottom of the top plate.
[0010] It can be seen that in the above technical solution, after the driving motor is started, the second pulley is driven to rotate by the belt, and then each first pulley can rotate through the belt, enabling the dispensing table to rotate in the middle of the limiting cylinder, realizing the functions of angle and position adjustment for dispensing the workpiece on the dispensing table. At the same time, by adjusting the angle of the shaft pin part, and then fixing the shaft pin part on the shaft pin seat with bolts, the angle of the elastic abutting block is adjusted. Then, in combination with the rotation of the dispensing table and the position adjustment of the elastic abutting block, and at the same time, the top plate is driven to move upward by the first electric push rod, so that the elastic abutting block can contact different positions of the workpiece, avoiding interference during dispensing and ensuring the convenience and efficiency during dispensing.
[0011] Technical effects and advantages of the present invention: In the present invention, the screw drive module drives the threaded hole block to drive each structure on the top plate and the support frame to adjust the position on the base, and then the dispensing table can approach the protective cover. At the same time, the second electric push rod drives the conveying conduit to drive the protective cover and the dispensing head to extend, so that the protective cover can be located on the circuit board, facilitating dispensing at different positions of the circuit board. At the same time, during dispensing, the protective cover blocks the dispensing head to avoid deviation of the dispensing trajectory caused by external interference. In the present invention, the third electric push rod drives the vibration motor and the elastic abutting block to displace, so that the elastic abutting block can abut against the workpiece. The amplitude generated by the start of the vibration motor is transmitted to the elastic abutting block, and due to the amplitude, the glue can be quickly flattened and dispersed, making the subsequent bonding of the two workpieces more firm. In the present invention, after the driving motor is started, the second pulley is driven to rotate by the belt, and then each first pulley can rotate through the belt, enabling the dispensing table to rotate in the middle of the limiting cylinder, realizing the functions of angle and position adjustment for dispensing the workpiece on the dispensing table and achieving diversity during dispensing. In the present invention, by adjusting the angle of the shaft pin part, and then fixing the shaft pin part on the shaft pin seat with bolts, the angle of the elastic abutting block is adjusted. Then, in combination with the rotation of the dispensing table and the position adjustment of the elastic abutting block, and at the same time, the top plate is driven to move upward by the first electric push rod, so that the elastic abutting block can contact different positions of the workpiece, avoiding interference during dispensing and ensuring the convenience and efficiency during dispensing. In summary, through the corresponding cooperation of each structure, the protective cover can be located on the circuit board, facilitating dispensing at different positions of the circuit board. At the same time, during dispensing, the protective cover blocks the dispensing head to avoid deviation of the dispensing trajectory caused by external interference. The elastic abutting block can abut against the workpiece, and the amplitude generated by the start of the vibration motor is transmitted to the elastic abutting block, and due to the amplitude, the glue can be quickly flattened and dispersed, making the subsequent bonding of the two workpieces more firm. The elastic abutting block can contact different positions of the workpiece, avoiding interference during dispensing and ensuring the convenience and efficiency during dispensing.

[0025] As shown in the attached Figure 1 - Figure 8An efficient dispensing device for SMT chip mounting is shown. Through the dispensing assembly provided on the base 1, the protective cover 203 can be located on the circuit board, facilitating dispensing at different positions of the circuit board. At the same time, during dispensing, the dispensing head 204 is blocked by the protective cover 203 to avoid deviation of the dispensing trajectory caused by external factors. The elastic abutting block 209 can abut against the workpiece. The amplitude generated by starting the vibration motor 208 is transmitted to the elastic abutting block 209, causing the glue liquid to quickly flatten and disperse due to the workpiece being affected by the amplitude, making the subsequent bonding of two workpieces more firm. The elastic abutting block 209 can contact different positions of the workpiece, avoiding interference during dispensing, ensuring the convenience and efficiency during dispensing, and the specific structure of the assembly is as follows; The dispensing assembly includes a protective box 101 provided on the top of the base 1. One side of the protective box 101 is provided with a support frame 102. One side of the support frame 102 is provided with a top plate 104 located on the top of the base 1. The bottom of the support frame 102 is provided with two first electric push rods 103, and the output ends of each first electric push rod 103 are fixed on one side of the support frame 102. The other end of the first electric push rod 103 is arranged at the bottom of the top plate 104. Connecting frames 105 are arranged on both sides of the dispenser 2, and the connecting frames 105 are installed on the protective box 101 by bolts. The top plate 104 is slidably connected to the support frame 102, and the top plate 104 is slidably connected to the base 1.
[0026] The inside of the protective box 101 is provided with a dispenser 2. The dispenser 2 is provided with a pump 201 for pressurization. One end of the dispenser 2 is provided with a delivery conduit 202. One end of the delivery conduit 202 is provided with a protective cover 203. Inside the protective cover 203 is provided a dispensing head 204 communicated with the delivery conduit 202. The top of the top plate 104 is provided with an inclined plate 206. Two third electric push rods 207 are arranged on the inclined plate 206. The output ends of the two third electric push rods 207 are both provided with vibration motors 208, and each vibration motor 208 is provided with an elastic abutting block 209. One side of the delivery conduit 202 is provided with a second electric push rod 205 for driving the displacement of the delivery conduit 202, and the second electric push rod 205 is installed on the dispenser 2.
[0027] A thread hole block 3 is provided at the bottom of the top plate 104, and a screw transmission module 301 for driving the thread hole block 3 to move is provided on the thread hole block 3, and the screw transmission module 301 is installed on the bottom of the base 1 by bolts, and first pulleys 302 are provided on both sides of the thread hole block 3, and a second pulley 304 is fixedly provided at the bottom of one of the first pulleys 302, and a driving motor 305 is installed on one side of the bottom of the thread hole block 3 by bolts, and the driving motor 305 is connected to the second pulley 304 and the two first pulleys 302 by belt 303 transmission, and a glue dispensing platform 307 is fixedly provided on the two first pulleys 302, and each glue dispensing platform 307 passes through the top plate 104 and extends to the bottom of the top plate 104.
[0028] According to the above structure, when in use, the staff installs the device at the designated position, places it on the glue dispensing table 307 when dispensing glue on the circuit board, drives the thread hole block 3 through the screw transmission module 301 to drive the top plate 104 and the various structures on the support frame 102 to adjust their positions on the base 1, and then enables the glue dispensing table 307 to be close to the protective cover 203.
[0029] At the same time, the second electric push rod 205 drives the delivery conduit 202 to extend the protective cover 203 and the dispensing head 204, so that the protective cover 203 can be located on the circuit board, which is convenient for dispensing glue at different positions of the circuit board. At the same time, the dispensing head 204 is blocked by the protective cover 203 during dispensing to prevent it from being disturbed by external factors and causing deviations in the dispensing trajectory.
[0030] At the same time, when the glue dispensing is completed, the third electric push rod 207 drives the vibration motor 208 and the elastic block 209 to move, so that the elastic block 209 can contact the workpiece, and the amplitude generated by the start-up of the vibration motor 208 is transmitted to the elastic block 209, so that the workpiece is affected by the amplitude, so that the glue can be quickly flattened and dispersed, so that the subsequent two workpieces are bonded more firmly.
[0031] And after the driving motor 305 is started, the second pulley 304 is driven to rotate via the belt 303, and then each first pulley 302 can rotate via the belt 303, so that the dispensing table 307 can rotate in the middle of the limiting cylinder 306, and the function of adjusting the angle and position of the workpiece during dispensing on the dispensing table 307 is realized. At the same time, by adjusting the angle of the axle pin 107, the axle pin 107 is fixed to the axle pin seat 106 by bolts, and then the angle of the elastic stop block 209 is adjusted, and then the dispensing table 307 rotates and the elastic stop block 209 is adjusted. The position is adjusted, and at the same time, the top plate 104 is driven to move upward by the first electric push rod 103, so that the elastic stop block 209 can contact with different positions of the workpiece to avoid interference during dispensing, thereby ensuring the convenience and efficiency of dispensing.
[0032] Different from the prior art, the present application discloses an efficient dispensing device for SMT patching. The protective cover 203 can be located on the circuit board, facilitating dispensing at different positions of the circuit board. Meanwhile, during dispensing, the protective cover 203 shields the dispensing head 204 to prevent it from being interfered by external factors and causing deviation in the dispensing trajectory. The elastic abutting block 209 can abut against the workpiece. The amplitude generated by starting the vibration motor 208 is transmitted to the elastic abutting block 209, causing the glue liquid to quickly flatten and disperse due to the amplitude acting on the workpiece, making the subsequent bonding of the two workpieces more firm. The elastic abutting block 209 can contact different positions of the workpiece, avoiding interference during dispensing and ensuring the convenience and efficiency during dispensing.
[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
