Description

Technical Field

[0001] The present invention relates to the technical field of circuit board dispensing, and more particularly to a high-efficiency dispensing device for SMT patches. Background Art

[0002] An SMT placement machine is a machine that performs a series of process steps on printed circuit boards (PCBs). SMT, standing for surface mount technology, is one of the most popular techniques and processes in the electronics assembly industry. A placement machine is a combination of mechanical, electrical, optical, and computer-controlled technologies. Through suction, displacement, positioning, and placement, it quickly and accurately places SMD components onto designated pads on PCBs. During the manufacturing of electronic products, dispensing glue is often required to achieve bonding between two workpieces.

[0003] Among them, the patent 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 cavity of the two second electric slide rails are slidably connected to the first electric slider near the rear side, the top 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;

[0004] When this structure is in use, the workpiece is clamped and fixed by the mutual cooperation between the clamping plate, the first rack plate, the worm gear, 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 weak bonding between the two subsequent workpieces. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an efficient SMT patch dispensing device, which aims to solve the problems raised in the above-mentioned background technology.

[0006] 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 provided.

[0007] The dispensing assembly includes a protective box arranged on the top of the base, a support frame is arranged on one side of the protective box, a top plate located on the top of the base is arranged on one side of the support frame, two first electric push rods are arranged at the bottom of the support frame, and the output end of each of the first electric push rods is fixed on one side of the support frame, and the other end of the first electric push rod is arranged at the bottom of the top plate, connecting frames are provided on both sides of the dispensing machine, and the connecting frames are installed on the protective box by bolts, the top plate is slidably connected to the support frame, and the top plate is slidably connected to the base.

[0008] It can be seen that in the above technical solution, the circuit board is placed on the dispensing table when dispensing glue, and the screw transmission module drives the wire hole block to drive the top plate and the various structures on the support frame to adjust their positions on the base, so that the dispensing table can be close to the protective cover, and the third electric push rod drives the vibration motor and the elastic block to move, so that the elastic block can contact the workpiece, and the amplitude generated by the start-up of the vibration motor is transmitted to the elastic block, so that the workpiece is affected by the amplitude, so that the glue can be quickly flattened and dispersed, so that the subsequent bonding of the two workpieces is more firmly.

[0009] A dispensing machine is provided inside the protective box, and a pump for pressurizing is provided on the dispensing machine. A delivery tube is provided at one end of the dispensing machine, and a protective cover is provided at one end of the delivery tube. A dispensing head connected to the delivery tube is provided in the protective cover, and an inclined plate is provided on the top of the top plate, and two third electric push rods are provided on the inclined plate. The output ends of the two third electric push rods are provided with vibration motors, and each of the vibration motors is provided with an elastic block. A second electric push rod for driving the displacement of the delivery tube is provided on one side of the delivery tube, and the second electric push rod is installed on the dispensing machine.

[0010] A wire hole block is provided at the bottom of the top plate, and a screw transmission module for driving the wire hole block to be displaced is provided on the wire hole block, and the screw transmission module is installed at the bottom of the base by bolts, and a first pulley is provided on both sides of the wire hole block, and a second pulley is fixedly provided at the bottom of one of the first pulleys, and a driving motor is installed on one side of the bottom of the wire hole block by bolts, and the driving motor is connected to the second pulley and the two first pulleys by belt transmission, and a dispensing platform is fixed on the two first pulleys, and each of the dispensing platforms passes through the top plate and extends to the bottom of the top plate.

[0011] It can be seen that in the above technical solution, the driving motor is started to drive the second pulley to rotate via the belt, and then each first pulley can be rotated via the belt, so that the dispensing table can rotate in the middle of the limit cylinder, and the function of adjusting the angle and position of the workpiece during dispensing on the dispensing table is realized. At the same time, by adjusting the angle of the axle pin part, and then fixing the axle pin part on the axle pin seat by bolts, the angle of the elastic block is adjusted, and then the position is adjusted in conjunction with the rotation of the dispensing table and the elastic block. At the same time, the top plate is driven to move upward by the first electric push rod, so that the elastic block can contact with different positions of the workpiece, avoiding interference during dispensing, and ensuring convenience and efficiency during dispensing.

[0012] The technical effects and advantages of the present invention are as follows:

[0013] The present invention drives the thread hole block through the screw transmission module to drive the top plate and various structures on the support frame to adjust their positions on the base, thereby allowing the dispensing platform to 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, making it convenient to dispense glue at different positions of the circuit board. At the same time, the protective cover blocks the dispensing head during dispensing, preventing it from being disturbed by external factors and causing deviation in the dispensing trajectory.

[0014] In the present invention, the third electric push rod drives the vibration motor and the elastic block to move, so that the elastic block can contact the workpiece. The amplitude generated by the start-up of the vibration motor is transmitted to the elastic block, so that the workpiece is subjected to the amplitude, which enables the glue to be quickly flattened and dispersed, so that the subsequent bonding of the two workpieces is more firmly.

[0015] The present invention starts the driving motor and drives the second pulley to rotate via the belt, which in turn enables each first pulley to rotate via the belt, so that the dispensing table can rotate in the middle of the limiting cylinder, thereby realizing the function of adjusting the angle and position of the workpiece during dispensing on the dispensing table, and realizing diversity in dispensing.

[0016] The present invention adjusts the angle of the shaft pin and then fixes the shaft pin on the shaft pin seat by means of bolts, thereby adjusting the angle of the elastic stop block. The position of the elastic stop block is then adjusted in conjunction with the rotation of the dispensing table and the elastic stop block. At the same time, the top plate is driven upward by the first electric push rod, so that the elastic stop block can contact different positions of the workpiece, thereby avoiding interference during dispensing and ensuring convenience and efficiency during dispensing.

[0017] To sum up, through the corresponding coordinated use of various structures, the protective cover 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 is blocked by the protective cover during dispensing to prevent it from being interfered with by external factors and causing deviations in the dispensing trajectory. The elastic block can contact the workpiece, and the amplitude generated by the start-up of the vibration motor is transmitted to the elastic block, so that the workpiece is affected by the amplitude, which enables the glue to be quickly flattened and dispersed, making the subsequent bonding of the two workpieces more firmly. The elastic block can contact different positions of the workpiece to avoid interference during dispensing, thereby ensuring convenience and efficiency during dispensing.

[0034] As attached Figure 1 - Figure 8The illustrated embodiment shows an efficient SMT patch dispensing device. Through the dispensing assembly provided on the base 1, the protective cover 203 can be positioned on the circuit board, making it convenient to dispense 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 interfered with by external factors and causing deviation in the dispensing trajectory. The elastic stop 209 can abut against the workpiece. The amplitude generated by the start-up of the vibration motor 208 is transmitted to the elastic stop 209, so that the workpiece is subjected to the amplitude, causing the glue to be quickly flattened and dispersed, making the subsequent bonding of the two workpieces more firmly. The elastic stop 209 can contact different positions of the workpiece to avoid interference during dispensing, thereby ensuring convenience and efficiency during dispensing. The specific structural arrangement of the assembly is as follows;

[0035] The dispensing assembly includes a protective box 101 arranged on the top of the base 1, a support frame 102 is arranged on one side of the protective box 101, and a top plate 104 located on the top of the base 1 is arranged on one side of the support frame 102. Two first electric push rods 103 are arranged at the bottom of the support frame 102, and the output end of each first electric push rod 103 is fixed on one side of the support frame 102, and the other end of the first electric push rod 103 is arranged at the bottom of the top plate 104. Connecting frames 105 are provided on both sides of the dispensing machine 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.

[0036] A dispensing machine 2 is provided inside the protective box 101, and a pump 201 for pressurizing is provided on the dispensing machine 2. A delivery tube 202 is provided at one end of the dispensing machine 2, and a protective cover 203 is provided at one end of the delivery tube 202. A dispensing head 204 connected to the delivery tube 202 is provided in the protective cover 203. An inclined plate 206 is provided on the top of the top plate 104, and two third electric push rods 207 are provided 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 block 209. A second electric push rod 205 for driving the displacement of the delivery tube 202 is provided on one side of the delivery tube 202, and the second electric push rod 205 is installed on the dispensing machine 2.

[0037] A wire hole block 3 is provided at the bottom of the top plate 104, and a screw transmission module 301 for driving the wire hole block 3 to move is provided on the wire hole block 3. The screw transmission module 301 is installed on the bottom of the base 1 by bolts. A first pulley 302 is provided on both sides of the wire hole block 3, and a second pulley 304 is fixedly provided at the bottom of one of the first pulleys 302. A driving motor 305 is installed on one side of the bottom of the wire hole block 3 by bolts. The driving motor 305 is connected to the second pulley 304 and the two first pulleys 302 by belt transmission 303. A dispensing platform 307 is fixed on the two first pulleys 302, and each dispensing platform 307 passes through the top plate 104 and extends to the bottom of the top plate 104.

[0038] When using the above structure, the staff installs the device at the designated position and places it on the dispensing table 307 when dispensing glue on the circuit board. The screw transmission module 301 drives the wire hole block 3 to drive the top plate 104 and the various structures on the support frame 102 to adjust their positions on the base 1, thereby allowing the dispensing table 307 to be close to the protective cover 203.

[0039] At the same time, the second electric push rod 205 drives the delivery tube 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 protective cover 203 blocks the dispensing head 204 during dispensing to prevent it from being interfered with by external factors and causing deviations in the dispensing trajectory.

[0040] At the same time, when the 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.

[0041] 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 be rotated via the belt 303, so that the dispensing platform 307 can rotate in the middle of the limiting cylinder 306, realizing the function of adjusting the angle and position of the workpiece during dispensing on the dispensing platform 307. At the same time, by adjusting the angle of the axle pin 107, and then fixing the axle pin 107 on the axle pin seat 106 by bolts, the angle of the elastic block 209 is adjusted, and then the position of the dispensing platform 307 and the elastic block 209 are adjusted. At the same time, the top plate 104 is driven to move upward by the first electric push rod 103, so that the elastic block 209 can contact different positions of the workpiece, avoiding interference during dispensing, and ensuring convenience and efficiency during dispensing.

[0042] Different from the prior art, the present application discloses an efficient SMT patch dispensing device, which can be located on the circuit board through the protective cover 203, making it convenient to dispense 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 interfered with by external factors and causing deviation in the dispensing trajectory. The elastic block 209 can abut against 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, which enables the glue to be quickly flattened and dispersed, making the subsequent bonding of the two workpieces more firmly. The elastic block 209 can contact different positions of the workpiece to avoid interference during dispensing, thereby ensuring convenience and efficiency during dispensing.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
