[0023] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1, the present utility model provides a dispensing device for realizing the automation of the dispensing process. Specifically, the dispensing device includes: a glue storage barrel 10, a conveying mechanism, and a dispensing mechanism 31. Among them, the glue storage barrel 10 is used to store glue; the conveying mechanism includes a connector 21, a hose 22, and a dispensing head 23. The connector 21 is communicated with the glue storage barrel 10, one end of the hose 22 is communicated with the connector 21, and the other end of the hose 22 is communicated with the dispensing head 23. Thus, the glue in the glue storage barrel 10 sequentially passes through the connector 21, the hose 22, and the dispensing head 23, and finally flows out from the dispensing head 23 and drops on the target position of the workpiece. The dispensing mechanism 31 includes a pair of opposing extrusion roller groups and a baffle 32. The hose 22 of the conveying mechanism is arranged between the extrusion roller groups and the baffle 32. Specifically, the extrusion roller groups include a plurality of extrusion rollers 311, and the plurality of extrusion rollers 311 are arranged at intervals in the length direction of the hose 22. The extrusion rollers 311 can be perpendicular to the hose 22, and each extrusion roller 311 can be individually moved in a direction perpendicular to the baffle 32 to extrude or release the hose 22.

[0025] That is to say, by arranging the hose 22 between the plurality of extrusion rollers 311 and the baffle 32, when the extrusion rollers 311 move towards the hose 22, due to the limiting effect of the baffle 32, the hose 22 cannot move, and the extrusion rollers 311 and the baffle 32 together form an extrusion on the hose 22, so that the glue in the hose 22 is extruded and then flows out from the dispensing head 23. When the plurality of extrusion rollers 311 respectively extrude the hose 22, if the displacement amounts of different extrusion rollers 311 are controlled to be different, the plurality of extrusion rollers 311 act together to cause the hose 22 to deform, and the cavity volume at the deformed part of the hose 22 is also basically fixed. That is, a fixed amount of glue in the hose 22 is separated, and then the fixed amount of glue is extruded through the movement of the plurality of extrusion rollers 311, so that the amount of glue extruded in each dispensing action is almost the same.

[0026] The numbers of the connector 21, the hose 22, and the dispensing head 23 can all be multiple. Each connector 21 can be communicated with one end of a corresponding hose 22, and the other end of each hose 22 can be respectively communicated with a dispensing head 23. The plurality of hoses 22 can be arranged on the side of the baffle 32 close to the extrusion rollers 311, and the plurality of hoses 22 can be arranged in parallel at intervals. The extrusion rollers 311 can simultaneously extrude the plurality of hoses 22 so that multiple hoses can be dispensed simultaneously. The interval distance of the plurality of hoses 22 in the length direction of the extrusion rollers 311 can be adjusted to achieve different dispensing positions. The surface of the extrusion rollers 311 can be provided with scale lines distributed in the length direction of the extrusion rollers 311, and through the scale lines, it is convenient to observe and adjust the interval distance and position of adjacent hoses 22 in the length direction of the extrusion rollers 311.

[0027] Such as Figure 2As shown, a limiting groove can be provided on the side of the baffle 32 close to the extrusion roller 311. The hose 22 can be arranged in the limiting groove. The inner wall surface of the limiting groove can be an arc-shaped curved surface. The depth of the limiting groove can be less than the radius of the hose 22, which can limit the hose 22 to prevent sliding, and at the same time prevent the extrusion roller 311 from over-extruding the hose during the extrusion process.

[0028] Thus, in the present utility model, by using a plurality of extrusion rollers 311 that can be individually controlled to extrude the soft glue for conveying glue, the control of different dispensing amounts can be achieved, the control accuracy of the glue amount is improved, and thus the effect of the dispensing process is enhanced.

[0029] In some embodiments, optionally, the extrusion roller group further includes a driving unit. The driving unit is in transmission connection with the extrusion roller 311, and the driving unit is used to drive each extrusion roller 311 to move individually in a direction perpendicular to the baffle 32. By providing the driving unit, the automatic control of the extrusion roller 311 is realized, and thus the automation of the dispensing process is achieved, and the dispensing efficiency is improved.

[0030] In other embodiments, optionally, the driving unit includes the same number of motors 312 as the extrusion rollers 311, and each motor 312 is in transmission connection with an extrusion roller 311. That is to say, a motor 312 is individually configured for each extrusion roller 311, so as to conveniently realize the individual control of each extrusion roller 311. Thus, all the motors 312 can be jointly adjusted so that the multiple motors 312 cooperate to drive the multiple extrusion rollers 311 to extrude the hose 22, making the deformation of the hose 22 almost the same each time. Exemplarily, the above-mentioned multiple motors 312 can all perform a same-frequency reciprocating motion, so that the motion trajectory formed by all the extrusion rollers 311 is wavy, or in the shape of a sine wave / cosine wave. There is the same phase difference between adjacent motors 312, and five phase differences just form a cycle. The 5 motors 312 complete a cycle of motion, thereby realizing the control of the dispensing amount within a single cycle.

[0031] In this embodiment, optionally, the dispensing mechanism 31 further includes a control unit. The control unit is electrically connected to the driving unit, and the control unit is used to control the displacement amount and moving speed of the driving unit to drive the extrusion roller 311. Through the control unit, the displacement amount and moving speed of the extrusion roller 311 can be conveniently controlled, and then the control of the dispensing amount and dispensing speed can be realized. Exemplarily, when it is necessary to change the dispensing amount, the displacement amount of the extrusion roller 311 can be controlled to change the amplitude of the periodic motion, thereby changing the dispensing amount within each cycle. And when it is necessary to change the dispensing speed, the moving speed of the extrusion roller 311 can be controlled to change the frequency, and then the speed of the dispensing can be controlled.

[0032] In some embodiments, optionally, the motor 312 is a voice coil motor. The voice coil motor has the characteristics of simple structure, small volume, high speed, high acceleration and fast response, which can reduce the volume of the dispensing device, reduce the noise generated by the dispensing device, and help improve the precision control of the dispensing amount and the precision control of the dispensing speed.

[0033] In some embodiments, optionally, the extrusion roller 311 is cylindrical. The cylindrical extrusion roller 311 can better push the hose 22. Since there are fewer parts in contact with the hose 22, it is convenient for the extruded glue to flow under the extrusion of multiple extrusion rollers 311. The drive shaft of the motor 312 is connected to the extrusion roller 311. The extrusion roller 311 can be driven to move through the drive shaft of the motor 312. Scale lines distributed along the length direction of the drive shaft can be provided on the outer surface of the drive shaft to facilitate judging the distance between the extrusion roller 311 and the baffle 32.

[0034] In some embodiments, optionally, the connector 21 is a Luer connector 21. The Luer connector 21 is a standardized micro leak-free connector 21, which can be conveniently connected to the glue storage barrel 10 and can control the amount of glue flowing into the hose 22.

[0035] In other embodiments, optionally, the number of the extrusion rollers 311 is at least 5. At least 5 extrusion rollers 311 can just form a complete cycle, thereby realizing the control of the dispensing amount. Of course, the number of extrusion rollers can also be more. In the case of having more extrusion rollers 311, the control of the dispensing amount will be more accurate.

[0036] Optionally, the dispensing device further includes a pressurizing mechanism, which is communicated with the glue storage barrel 10 and is used to apply air pressure to the glue storage barrel 10. That is to say, since the glue has a certain viscosity, by applying a certain air pressure to the glue storage barrel 10 through the pressurizing mechanism, the preliminary supply of the glue can be realized, so that the glue flows out from the Luer connector 21 into the hose 22.

[0037] Optionally, one side of the hose 22 facing the baffle 32 is fixedly connected to the baffle 32. In this embodiment, the baffle 32 is used to fix the hose 22, that is, one side of the hose 22 facing the baffle 32 is fixedly connected to the baffle 32. During the movement of the extrusion roller 311, the contact position between the hose 22 and the baffle 32 always remains fixed, avoiding the inconsistent deformation amount of the hose 22 squeezed by the extrusion roller 311, which may cause inconsistent dispensing amounts. Exemplarily, the hose 22 can be adhered to the baffle 32 by means of glue bonding.

[0038] In summary, in the present utility model, by extruding the soft glue for conveying glue through a plurality of separately controllable extrusion rollers, the control of different dispensing amounts can be achieved, the control accuracy of the glue amount is improved, and thus the effect of dispensing processing is enhanced.
