Referring to fig. 1 to 6, a paste ejection apparatus 100 according to an embodiment of the invention is shown.

As shown in fig. 1 and 6, the paste ejection apparatus 100 includes: a positioning mechanism 10 and a glue-extruding mechanism 20. The positioning mechanism 10 is used for fixing the head of the glue bottle 200, and the glue squeezing mechanism 20 is used for squeezing the two sides of the glue bottle 200 to force the glue to flow out from the glue outlet of the glue bottle 200.

Hereinafter, the above-mentioned paste ejection apparatus 100 will be further described with reference to fig. 2 to 6 on the basis of fig. 1.

As shown in fig. 2 and 3, in the present embodiment, the positioning mechanism 10 includes: a clamp 11 and an adjustable screw 12 connected to the clamp 11. The adjustable screw 12 is used to adjust the degree of clamping of the clamp 11. When fixing the glue bottle 200, the glue bottle 200 is first put into the clamp 11, and then the adjustable screw 12 is screwed to tighten the clamp 11 so as to fix the glue bottle 200.

In the present embodiment, the positioning mechanism 10 is operated by manual positioning. In other embodiments, the positioning mechanism 10 may also be implemented in other ways. For example, in other embodiments, the positioning mechanism 10 may include: clamping jaw and the clamp finger cylinder of connecting the clamping jaw. The clamping fingers are controlled by the clamping finger cylinder to be closed so as to clamp the glue bottle 200. For another example, in other embodiments, the clamp 11 may be configured to include: the fixing part and the movable part drive the movable part to move towards the fixing part by arranging a driver so as to lock the glue bottle 200.

As shown in fig. 4, in the present embodiment, the paste ejection mechanism 20 includes: a slide unit 21 and a paste ejection unit 22 mounted on the slide unit 21. The sliding unit 21 is used to drive the glue-squeezing unit 22 to move, and the glue-squeezing unit 22 is used to press the glue bottle 200 to force the glue to flow out.

There are various implementations possible for the slide unit 21.

For example, in the present embodiment, as shown in fig. 4, the slide unit 21 includes: a slide 211 connected to the paste ejection unit 22, and a first driver 212 connected to the slide 211. The first driver 212 is used for driving the sliding base 211 to move so as to drive the paste-ejecting unit 22 to move. By using the first driver 212 as a power source to drive the glue-extruding unit 22 to move, automatic glue extruding can be realized, and the working efficiency can be improved. In addition, in the present embodiment, the first driver 212 is a servo motor, and in other embodiments, the first driver 212 may also be a stepping motor or other motors with good controllability. The first driver 212 may also be a combination of a servo motor and a speed reducer if there is a high demand for torque and position locking of the output.

Further, in the present embodiment, the first driver 212 is connected to the sliding base 211 through a lead screw structure, for example, the first driver 212 is connected to the lead screw, the sliding base 211 is connected to a nut sleeve sleeved on the lead screw, the first driver 212 drives the lead screw to rotate to drive the nut sleeve to move linearly, and further drives the sliding base 211 to move linearly. In other embodiments, the first driver 212 and the sliding base 211 can be connected by a rack structure, for example, the first driver 212 is connected to a gear, the sliding base 211 is connected to a rack of a meshing gear, and the first driver 212 drives the gear to rotate to drive the rack to move linearly, thereby driving the sliding base 211 to move linearly.

It should be noted that, in the present embodiment, the movement track of the sliding unit 21 is a linear movement, which conforms to the design shape of most glue bottles 200 and facilitates controlling the glue discharging of the glue bottles 200. It is understood that the motion track of the sliding unit 21 may be a curve for a special shaped glue bottle 200 or for a special requirement on the glue discharging speed. For the motion trail of the curve, a cam structure can be adopted.

Various implementations are also possible for the paste ejection unit 22.

For example, in the present embodiment, as shown in fig. 4, the paste ejection unit 22 includes: a first rolling member 221 and a second rolling member 222 disposed in parallel to the first rolling member 221. The first rolling member 221 and the second rolling member 222 serve to press both sides of the glue bottle 200.

As for the first rolling member 221 and the second rolling member 222, a roller or a roller shaft may be used, and the specific choice may be determined according to the width of the glue bottle 200, or a roller set or a roller shaft set may be used.

In practical applications, the distance between the first rolling member 221 and the second rolling member 222 needs to be adjusted adaptively to take account of the fact that the thickness of different glue bottles 200 may be different. For the purpose of adjustability, manual or automated settings may be used.

Taking an automated arrangement as an example, as shown in fig. 4, for example, in the present embodiment, the paste ejection unit 22 further includes: and a second driver 223 coupled to the sliding unit 21. The second driver 223 is connected to the first roller 221 and/or the second roller 222. The second driver 223 is used to adjust the distance between the first roller 221 and the second roller 222. The distance between the first rolling member 221 and the second rolling member 222 can be adjusted to adapt to glue bottles 200 of different sizes by using the second driver 223 as a power source to drive the first rolling member 221 and the second rolling member 222 to move close to or away from each other. Further, in the present embodiment, the second actuator 223 is connected to the first roller 221 and the second roller 222, respectively, and thus, the second actuator 223 is a finger clamping cylinder. In other embodiments, the second actuator 223 may be coupled to one of the first roller 221 and the second roller 222, in which case the second actuator 223 may select a single-side push cylinder.

For the manual setting, the paste ejection unit 22 may further include: a bracket slidably coupling the first roller 221 and the second roller 222. The bracket is provided with a sliding groove for sliding the first rolling member 221 and the second rolling member 222, and is correspondingly provided with a locking member.

For the glue bottle 200 with a large length, when the glue squeezing unit 22 works, the glue bottle 200 is easily bent due to rolling extrusion of the first rolling member 221 and the second rolling member 222, that is, a bulge occurs between the head of the glue bottle 200 and the squeezed place of the glue bottle 200 due to rolling extrusion, which may cause the glue squeezing unit 22 to be stuck or prevent the glue of the glue bottle 200 from flowing out or affect the control of the glue output of the glue bottle 200. Therefore, as shown in fig. 1, in the present embodiment, the paste ejection apparatus 100 further includes: an auxiliary mechanism 30 for fixing the tail of the glue bottle 200. For the glue bottle 200 with a large length or a small hardness, in the process of rolling and pressing the glue bottle 200 by the first rolling member 221 and the second rolling member 222, the glue bottle 200 may be bent under the action of the first rolling member 221 and the second rolling member 222, so that the glue bottle is stuck or difficult to discharge glue. Therefore, the auxiliary mechanism 30 is arranged to fix the tail of the glue bottle 200, so that the glue bottle 200 can be prevented from being bent in the glue squeezing process.

Further, as shown in fig. 5, in the present embodiment, the assist mechanism 30 includes: the clamping unit 31 is used for clamping the clamping unit 31 at the tail of the glue bottle 200. The tail of the glue bottle 200 is clamped by the clamping unit 31, so that the tail of the glue bottle 200 is fixed.

Further, in the present embodiment, the clamping unit 31 includes: a first clamping block 311, a second clamping block 312 arranged parallel to the first clamping block 311, and a third driver 313 connecting the first clamping block 311 and/or the second clamping block 312. The third driver 313 is used to adjust the distance between the first clamping block 311 and the second clamping block 312. When the tail of the glue bottle 200 needs to be clamped, the third driver 313 drives the first clamping block 311 and the second clamping block 312 to approach each other, so that the first clamping block 311 and the second clamping block 312 clamp the tail of the glue bottle 200.

In other embodiments, the clamping unit 31 may include: the clamping finger cylinder and the clamping jaw arranged on the clamping finger cylinder can also achieve the purpose of clamping and fixing the tail part of the glue bottle 200.

It is understood that in other embodiments, the clamping unit 31 may also include: a pincer or clip for holding the tail of the glue bottle 200.

In addition, in order to be suitable for glue bottles 200 with different lengths, the clamping unit 31 may be a sliding device, which can be adjusted in position according to the glue bottles 200 with different lengths.

As shown in fig. 1, in the present embodiment, the paste ejection apparatus 100 further includes: the sensor 40 of the first driver 212 is electrically connected. A sensor 40 is arranged towards the positioning means 10 to detect the position of the glue extrusion. As shown in fig. 6, when the sensor 40 detects that the extrusion amount of the glue has reached the preset required amount during the process that the first driver 212 drives the glue extrusion unit 22 to extrude the glue, the sensor 40 sends a pause signal to the first driver 212, and the first driver 212 pauses operation.

Further, in this embodiment, the sensor 40 is a non-contact laser sensor 40, and the sensor 40 is triggered when the amount of glue squeezed out reaches a predetermined amount.

When the glue-squeezing device 100 is used, the head of the glue bottle 200 is fixed to the positioning mechanism 10. Then, the sliding unit 21 in the glue-squeezing unit 22 drives the glue-squeezing unit 22 to move, so that the first rolling member 221 and the second rolling member 222 on the glue-squeezing unit 22 roll and squeeze two sides of the glue bottle 200, the glue in the glue bottle 200 is forced to flow out from the positioning mechanism 10, and the glue-discharging amount can be controlled by controlling the moving distance of the sliding unit 21. Through the design, the mechanized glue extruding operation is realized, the glue is prevented from being stuck on the hand of a user when being extruded, the safety is improved, the continuity and the stability of the mechanized operation are good, and the improvement of the working efficiency is facilitated.

Example two

Fig. 7 shows a paste ejection apparatus 100a according to another embodiment of the invention.

The difference between this embodiment and the first embodiment is: in this embodiment, the paste ejection apparatus 100a further includes: and a sealing mechanism 50 for blocking the glue outlet of the glue bottle 200. When the standby waiting adhesive operation is needed, if the glue outlet of the glue bottle 200 is exposed in the air for a long time, the glue outlet is easily blocked due to the solidification of the glue, and at this time, the glue outlet of the glue bottle 200 can be blocked by the sealing mechanism 50.

Further, there may be a variety of specific implementations for the sealing mechanism 50.

For example, as shown in fig. 7, in the present embodiment, the sealing mechanism 50 includes: a cover 51 and a fourth driver 52 connected to the cover 51. The fourth driver 52 is used to drive the cover 51. The fourth driver 52 is used for driving the sealing cap 51 to move so as to adjust the position of the sealing cap 51, thereby realizing the sealing of the glue outlet of the glue bottle 200 or keeping away from the glue outlet of the glue bottle 200. In this embodiment, the fourth driver 52 is a rotary pressing cylinder, and when the sealing cap 51 needs to be cleared from the glue outlet of the glue bottle 200, the fourth driver 52 drives the sealing cap 51 to ascend and rotate to one side of the glue bottle 200.

For another example, in other embodiments, the sealing mechanism 50 may include: the flip cover is hinged on the positioning mechanism 10, and the position of the flip cover is controlled in a manual turnover mode.

Other structures of the present embodiment are the same as those of the first embodiment, and the beneficial effects of the first embodiment can also be achieved.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only express preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
