Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to a numerical measurement test box. Background Art

[0002] In the assembly process of electronic components and electronic products, welding assembly processes are gradually being replaced by glue bonding processes due to many limitations such as spatial positioning, heat source diffusion, complex curved surfaces, and refined control. It can be foreseen that the dispensing process will play an increasingly important role in the manufacturing process of consumer electronics and their components due to its advantages such as flexible operation, reliable performance, design freedom, and no heat radiation to components.

[0003] After searching, the Chinese patent publication number CN212820795U discloses "a glue dispensing machine, including a linear supply mechanism for continuously outputting glue, a heating chamber for heating the glue, and a glue dispensing nozzle for outputting the heated glue, the input end of the heating chamber is connected to the linear supply mechanism, and the output end of the heating chamber is connected to the glue dispensing nozzle."

[0004] The above patent introduces glue into the dispensing nozzle through the feed bin, and then dispenses glue to the electronic components through the dispensing nozzle. Although the dispensing nozzle can continuously dispense glue to the electronic components, the amount of glue dispensed by the dispensing nozzle each time cannot be determined, and it cannot be guaranteed that the glue dispensed each time is the same, which may cause the problem of insufficient glue dispensed to some electronic components. In addition, there are intervals when dispensing glue to different electronic components. If the dispensing nozzle continues to dispense glue during this process, it will cause waste of glue.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 2 The utility model provides a numerical measurement test box, including a box body 1, one end of the box body 1 is fixedly connected to a rubber outlet pipe 3, one end of the bottom of the box body 1 is fixedly connected to a rubber inlet pipe 2, a corresponding control valve is fixedly installed on the rubber inlet pipe 2, the inner side of the box body 1 is slidably connected to a piston plate 4, one side of the piston plate 4 is fixedly connected to a screw 5, one end of the screw 5 away from the piston plate 4 penetrates the side wall of the box body 1 and extends to the outside of the box body 1, the screw 5 is slidably connected to the side wall of the box body 1, the outer wall of the box body 1 is provided with a driving mechanism 6 for driving the screw 5 to slide, and the end of the screw 5 away from the piston plate 4 is provided with a measuring mechanism 7 for measuring the rubber output amount of the rubber outlet pipe 3.

[0024] The driving mechanism 6 drives the screw 5 to slide into the box body 1, which makes the screw 5 push the piston plate 4 to slide close to the glue outlet pipe 3, which increases the pressure inside the box body 1, so that the glue inside the box body 1 is discharged from the glue outlet pipe 3. At the same time, the measuring mechanism 7 can measure the glue discharged from the glue outlet pipe 3, and then determine whether the glue discharged from the glue outlet pipe 3 is consistent each time, which is beneficial to improve the dispensing quality of the glue dispensing machine for electronic components.

[0025] Reference Figure 3 The measuring mechanism 7 includes two parallel guide seats 71, both of which are fixedly connected to the top wall of the box body 1, and a measuring block 72 is slidably connected between the two guide seats 71. The measuring block 72 is arranged in parallel with the piston plate 4, and one side of the measuring block 72 is in the same vertical plane as one side of the piston plate 4. One end of the measuring block 72 is fixedly connected to a movable rod 73, and one end of the movable rod 73 away from the measuring block 72 is fixedly connected to a connecting plate 74, and the bottom end of the connecting plate 74 is fixedly connected to the end of the screw 5, and the top surfaces of the two guide seats 71 are fixedly connected to dials 75. When the screw 5 pushes the piston plate 4 to slide close to the rubber outlet pipe 3, the screw 5 drives the connecting plate 74 to move synchronously at the same time, which makes the movable rod 73 push the measuring block 72 to slide along the guide seat 71. Since the measuring block 72 and the side of the piston plate 4 are in the same vertical plane, the displacement change of the measuring block 72 is also the displacement of the piston plate 4. The displacement of the measuring block 72 can be observed through the dial 75, so that the displacement of the piston plate 4 can be determined, and then the reduction of the rubber inside the box body 1 can be calculated, and the amount of rubber discharged from the rubber outlet pipe 3 can be obtained.

[0026] Reference Figure 4 - Figure 5The driving mechanism 6 includes an internal threaded sleeve 61, which is rotatably connected to the outer wall of the box body 1 and is threadedly connected to the screw 5. One end of the internal threaded sleeve 61 is fixedly connected to a ratchet 62. One end of the outer wall of the box body 1 is provided with a power component 63 for driving the ratchet 62 to rotate intermittently. The power component 63 includes a rotating seat 631. The bottom end of the rotating seat 631 is rotatably connected to the outer wall of the box body 1 through a pin shaft. One end of the top of the rotating seat 631 is rotatably connected to a pawl 632. The pawl 632 is slidably matched with the tooth groove of the ratchet 62. The other end of the top of the rotating seat 631 is rotatably connected to a connecting piece 635. A motor 633 is fixedly installed on the top of the outer wall of the box body 1. The output shaft of the motor 633 is fixedly connected to an eccentric wheel 634. The outer edge of the eccentric wheel 634 is rotatably connected to one end of the connecting piece 635. By starting the motor 633 to drive the eccentric wheel 634 to rotate, the connecting piece 635 drives the rotating seat 631 to swing back and forth, so that the pawl 632 intermittently slides with the tooth groove of the ratchet 62. When the pawl 632 cooperates with the tooth groove of the ratchet 62, the ratchet 62 is driven to rotate, which makes the ratchet 62 rotate intermittently, and then the internal threaded sleeve 61 rotates intermittently, which makes the screw 5 intermittently drive the piston plate 4 to slide close to the rubber outlet pipe 3, which increases the pressure inside the box body 1, so that the rubber inside the box body 1 is discharged from the rubber outlet pipe 3.

[0027] Reference Figure 6 The connecting member 635 includes a connecting rod 6351, one end of which is rotatably connected to the outer edge of the eccentric wheel 634 through a pin shaft, and one end of the top of the rotating seat 631 is rotatably connected to a connecting screw 6353, one end of the connecting screw 6353 penetrates the connecting rod 6351 and extends to the outside of the connecting rod 6351, and the threaded section of the connecting screw 6353 is threadedly connected to a locking nut 6354, and the locking nut 6354 is in conflict with the side wall of the connecting rod 6351, and a sliding groove 6352 is opened on the side wall of the connecting rod 6351 along the length direction of the connecting rod 6351, and the connecting screw 6353 is slidably connected to the inner wall of the sliding groove 6352. By loosening the locking nut 6354, the connecting screw 6353 can slide along the slide groove 6352, so that the distance between the connecting screw 6353 and the eccentric wheel 634 can be adjusted, thereby adjusting the swing period of the rotating seat 631, and further adjusting the rotation period of the ratchet 62 and the internal threaded sleeve 61, and thus adjusting the sliding interval time of the piston plate 4. In this way, the interval time of discharging the material from the hose 3 can be determined by the switching time of different electronic components at equal intervals.

[0028] The working principle of the utility model is as follows: by starting the motor 633 to drive the eccentric wheel 634 to rotate, the connecting member 635 drives the rotating seat 631 to swing back and forth, so that the pawl 632 intermittently slides with the tooth groove of the ratchet 62, and the pawl 632 cooperates with the tooth groove of the ratchet 62 to drive the ratchet 62 to rotate, which also makes the ratchet 62 rotate intermittently, and then makes the internal threaded sleeve 61 rotate intermittently, which makes the screw 5 intermittently drive the piston plate 4 to slide close to the rubber outlet pipe 3, which increases the pressure inside the box body 1, so that the rubber inside the box body 1 is intermittently discharged from the rubber outlet pipe 3, so that the problem of rubber waste caused by the rubber being discharged during the switching process of different electronic components can be avoided;

[0029] When the screw 5 pushes the piston plate 4 to slide close to the rubber outlet pipe 3, the screw 5 drives the connecting plate 74 to move synchronously at the same time, which makes the movable rod 73 push the measuring block 72 to slide along the guide seat 71. Since the measuring block 72 and the side of the piston plate 4 are in the same vertical plane, the displacement change of the measuring block 72 is also the displacement of the piston plate 4. The displacement of the measuring block 72 can be observed through the dial 75, so that the displacement of the piston plate 4 can be determined, and then the reduction of the rubber inside the box body 1 can be calculated, and the amount of rubber discharged from the rubber outlet pipe 3 can be obtained.

[0030] 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 protection scope of the present invention.
