[0041] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, the utility model discloses a glue mixing device, which includes a housing 100, a first driving mechanism 200, a second driving mechanism 300 and a mixing mechanism 400; the housing 100 has a first discharge channel 110, a second discharge channel 120 and a mixing channel 130; the first discharge channel 110 has a first discharge port 111; the second discharge channel 120 has a second discharge port 121; both the first discharge port 111 and the second discharge port 121 are communicated with the mixing channel 130; the first driving mechanism 200 is connected to the housing 100 and can convey the liquid in the first discharge channel 110 to the first discharge port 111; the second driving mechanism 300 is connected to the housing 100 and can convey the liquid in the second discharge channel 120 to the second discharge port 121; the mixing mechanism 400 is connected to the housing 100 and includes a mixing part 410, and the mixing part 410 is accommodated in the mixing channel 130 and is used for mixing the liquid in the mixing channel 130.
[0042] Inside the housing 100, there are a first discharge channel 110, a second discharge channel 120 and a mixing channel 130 that are interconnected. The first driving mechanism 200 and the second driving mechanism 300 can make the liquid flow directly from the inside of the first discharge channel 110 and the inside of the second discharge channel 120 to the mixing channel 130. The mixing mechanism 400 directly mixes the liquid entering the mixing channel 130, so that the conveyance and mixing of the liquid are both carried out inside the housing 100, and the overall structure of the glue mixing device is more compact, thereby enabling the overall specification of the glue mixing device to be reduced.
[0043] Please refer to Figure 1 As shown in the figure, in some embodiments, the glue mixing device can be arranged inside a box body 700. A handle 710 is connected to the outer surface of the box body 700 and a glue outlet 720 communicated with the mixing channel 130 is provided. The housing 100 is fixedly connected inside the box body 700. Then, the staff can move the box body 700 by holding the handle 710 according to actual needs, thereby realizing the portable movement and handling of the glue mixing device.
[0044] Of course, it can be understood that since the overall structure of the glue mixing device of the present utility model is relatively compact and suitable for overall movement, based on this, in some alternative embodiments, the glue mixing device can be connected to a movable module through the housing 100 and cooperate with the dispensing device on the module, so that the entire glue mixing device can move along with the module to perform dispensing on different parts of the product. Since the glue mixing device of the present utility model is more compact than the glue mixing devices in the prior art, it can further increase the flexibility of the dispensing device for dispensing. For the solution of realizing the movement of the glue mixing device along with the module, without departing from the inventive concept of the present utility model, the module can be a manipulator, an electromagnetic chuck or a magnetic drive wire conveying system, etc. The module can preset a dispensing trajectory according to the dispensing requirements of the product. When the housing 100 is installed on the module, the glue mixing device can be driven by the module to move along the preset dispensing trajectory to realize the dispensing function.
[0045] For the solution of realizing the mixing of liquids by the mixing part 410, please refer to Figure 4 As shown, in some embodiments, the mixing part 410 is a common spiral blade. The spiral blade can rotate around the axis of the mixing channel 130 and stir the liquid in the mixing channel 130 to achieve a mixing effect. Without departing from the inventive concept of the present utility model, the mixing part 410 can also be a structure with other shapes that meet the stirring function.
[0046] Please refer to Figure 2 、 Figure 3 、 Figure 4 As shown, in some embodiments, both the first driving mechanism 200 and the second driving mechanism 300 are screw pumps. The screw pump can extrude the liquid in the stator channel to the discharge channel through the rotation of the rotor, thereby further squeezing the liquid originally in the discharge channel, so that the liquid gradually flows to the discharge port; in some other embodiments, both the first driving mechanism 200 and the second driving mechanism 300 are peristaltic pumps. The peristaltic pump pumps the liquid to the discharge channel through internal rotation, thereby further squeezing the rated liquid originally in the discharge channel, so that the liquid gradually flows to the discharge port. Without departing from the inventive concept of the present utility model, those skilled in the art can freely select the structural forms of the first driving mechanism 200 and the second driving mechanism 300, and the structural forms of the first driving mechanism 200 and the second driving mechanism 300 can also be different.
[0047] It should be noted that when the driving mechanism is a screw pump, in some embodiments, the structure for forming the stator channel of the screw pump can be integrally connected to the housing 100; in some other embodiments, the stator channel of the screw pump is directly formed inside the housing 100; the above embodiments can further reduce the assembly gap between the driving mechanism and the housing 100 and further increase the compactness of the glue mixing device.
[0048] Furthermore, please refer toFigure 2 , Figure 3 , Figure 4 As shown in Figure 4 , in some embodiments, the extending direction of the first discharge channel 110 is the direction from one end to the other end of the first discharge channel 110 on the axis of the first discharge channel 110; the extending direction of the second discharge channel 120 is the direction from one end to the other end of the second discharge channel 120 on the axis of the second discharge channel 120. That is to say, both the first discharge channel 110 and the second discharge channel 120 are straight extending channels, rather than curved extending channels. Through the above solution, the liquid in the discharge channel can directly move along the extending direction of the discharge channel to the discharge port and enter the mixing channel 130. During the transportation process of the liquid in the discharge channel, it will not be subjected to the supporting force from the inner wall of the discharge channel in the opposite direction to the transportation direction, reducing the power loss of the liquid during the transportation process, and thus being beneficial to reducing the power requirement of the driving mechanism and saving energy.
[0049] Further, please refer to Figure 2 , Figure 3 , Figure 4 As shown in Figure 4 , in some embodiments, the first driving mechanism 200 is a screw pump, including a first rotor 210, and further having a first stator channel 220. The first stator channel 220 is in communication with the first discharge channel 110 and has the same extending direction. The first rotor 210 is accommodated in the first stator channel 220 and can rotate relative to the inner wall of the first stator channel 220 to transport the liquid in the first stator channel 220 along the extending direction of the first discharge channel 110. Since the rotation of the first rotor 210 causes the liquid in the first stator channel 220 to be transported along the extending direction of the first discharge channel 110, when the liquid in the first stator channel 220 moves to the first discharge channel 110, the inner wall of the first discharge channel 110 will not exert a supporting force on the liquid in the opposite direction to the transportation direction of the first mover, reducing the power loss of the liquid during the transfer from the first stator channel 220 to the first discharge channel 110, and thus further being beneficial to reducing the power requirement of the first driving mechanism 200 and saving energy.
[0050] In some embodiments, the second driving mechanism 300 is a screw pump, including a second rotor 310, and further having a second stator channel 320. The second stator channel 320 communicates with the second discharge channel 120 and has the same extending direction. The second rotor 310 is accommodated in the second stator channel 320 and can rotate relative to the inner wall of the second stator channel 320 to convey the liquid in the second stator channel 320 along the extending direction of the second discharge channel 120. Since the rotation of the second rotor 310 causes the liquid in the second stator channel 320 to be conveyed along the extending direction of the second discharge channel 120, when the liquid in the second stator channel 320 moves to the second discharge channel 120, the inner wall of the second discharge channel 120 will not exert a supporting force on the liquid in the direction opposite to the conveying direction of the second mover, reducing the power loss of the liquid during the transfer from the second stator channel 320 to the second discharge channel 120, thereby further facilitating the reduction of the power requirement of the second driving mechanism 300 and saving energy.
[0051] Further, please refer to Figure 3 、 Figure 4 As shown, in some embodiments, the axes of the first discharge channel 110, the second discharge channel 120, and the mixing channel 130 intersect at a point, and the intersection point is located in the mixing channel 130. Through the above scheme, the liquid in the first discharge channel 110 can directly flow along the extending direction of the first discharge channel 110 to the axis in the mixing channel 130, and the liquid in the second discharge channel 120 can directly flow along the extending direction of the second discharge channel 120 to the axis in the mixing channel 130; the liquid in the first discharge channel 110 and the liquid in the second discharge channel 120 can directly contact each other at the axis in the mixing channel 130, which is beneficial to the mixing of the liquid in the mixing channel 130 and increases the mixing efficiency.
[0052] Further, please refer to Figure 3 、 Figure 4 As shown, in some embodiments, the first discharge channel 110 and the second discharge channel 120 are symmetrically arranged with respect to the plane passing through the axis of the mixing channel 130. The above scheme can further simplify the channel design inside the housing 100 and simplify the process of machining the housing 100.
[0053] As previously mentioned, the driving mechanism can be a screw pump and can convey the liquid in the stator channel along the extending direction of the discharge channel; in some preferred embodiments, the first driving mechanism 200 and the second driving mechanism 300 are symmetrically arranged with respect to the plane passing through the axis of the mixing channel 130, so as to further simplify the form of the driving mechanism. The first driving mechanism 200 and the second driving mechanism 300 can use screw pumps of the same specification, reducing the cost of the rubber mixing device.
[0054] Further, please refer to Figure 3 、Figure 4 As shown, in some embodiments, the first discharge port 111 is located at the lower end of the first discharge channel 110, the second discharge port 121 is located at the lower end of the second discharge channel 120, and the mixing channel 130 extends downward relative to the first discharge port 111 and the second discharge port 121. Through the above solution, the liquid flowing out of the discharge port continues to flow downward under the action of gravity, thereby reducing the residue of the liquid at the discharge port and reducing the power required for the driving mechanism to transport the liquid.
[0055] As a preferred solution, please refer to Figure 4 As shown, on the basis of the above solution, the extending direction of the first discharge channel 110 is the direction from one end to the other end of the first discharge channel 110 on the axis of the first discharge channel 110, and the extending direction of the second discharge channel 120 is the direction from one end to the other end of the second discharge channel 120 on the axis of the second discharge channel 120; the axes of the first discharge channel 110, the second discharge channel 120, and the mixing channel 130 intersect at a point and the intersection point is located in the mixing channel 130, and the first discharge channel 110 and the second discharge channel 120 are symmetrically arranged with respect to the plane passing through the axis of the mixing channel 130. Through the above solution, please refer to Figure 4As shown, taking the intersection of the axis of the first discharge channel 110, the axis of the second discharge channel 120, and the axis of the mixing channel 130 as the upper and lower boundary, the upper half of the axis of the first discharge channel 110 and the lower half of the axis of the mixing channel 130 form an obtuse angle, and the upper half of the axis of the second discharge channel 120 and the lower half of the axis of the mixing channel 130 form an obtuse angle, so that the first discharge channel 110 and the second discharge channel 120 utilize the space above the mixing channel 130, thereby reducing the space occupied by the first discharge channel 110 and the second discharge channel 120 in the horizontal direction, and the overall layout is more compact. Further, the included angle between the upper half of the axis of the first discharge channel 110 and the lower half of the axis of the mixing channel 130 is 160 - 170°, for example, the included angle between the upper half of the axis of the first discharge channel 110 and the lower half of the axis of the mixing channel 130 is 160°, 162°, 165° or 170°. The included angle between the upper half of the axis of the second discharge channel 120 and the lower half of the axis of the mixing channel 130 is 160 - 170°, for example, the included angle between the upper half of the axis of the second discharge channel 120 and the lower half of the axis of the mixing channel 130 is 160°, 162°, 165° or 170°. The above range can preferably incline the first discharge channel 110 and the second discharge channel 120, making it easier for the liquid to slide down along the discharge channel; and avoiding interference between the first driving mechanism 200 and the second driving mechanism 300. In some preferred embodiments, the included angle between the upper half of the axis of the first discharge channel 110 and the lower half of the axis of the mixing channel 130 is 165°, and the included angle between the upper half of the axis of the second discharge channel 120 and the lower half of the axis of the mixing channel 130 is 165°.
[0056] Further, please refer to Figure 1 , Figure 5 As shown, in some embodiments, the glue mixing device further includes a storage mechanism 500. The storage mechanism 500 includes a first glue bucket 510 and a first valve 530. The first glue bucket 510 has a first accommodating cavity, and the first accommodating cavity communicates with the first discharge channel 110. The first valve 530 is used to switch the on-off between the first accommodating cavity and the first discharge channel 110. The above solution enables the glue mixing device to store a kind of liquid in the first glue bucket 510, and enables the staff to switch the first valve 530 to adjust whether the liquid in the first glue bucket 510 flows into the first discharge channel 110.
[0057] Further, please refer to Figure 5 As shown, wherein Figure 5Only the first vacuum pump interface 550 for connecting the first vacuum pump is shown. In some embodiments, the storage mechanism 500 further includes a first vacuum pump. The first vacuum pump is communicated with the first accommodating cavity through the first vacuum pump interface 550 and is used to extract the air in the first accommodating cavity when the first valve 530 cuts off the connection between the first accommodating cavity and the first discharge channel 110. When the first valve 530 is cut off, the first vacuum pump can extract the air in the first accommodating cavity and reduce the air content in the first accommodating cavity. Then, when the first valve 530 is opened, the air content in the liquid in the first accommodating cavity is lower, and it is less likely to generate bubbles inside after mixing with the liquid in the second discharge channel 120, thereby improving the quality of the glue.
[0058] Please refer to Figure 1 、 Figure 6 As shown, in some embodiments, the storage mechanism 500 includes a second glue bucket 520 and a second valve 540. The second glue bucket 520 has a second accommodating cavity, and the second accommodating cavity is communicated with the second discharge channel 120. The second valve 540 is used to switch the connection between the second accommodating cavity and the second discharge channel 120 on and off. The above solution enables the glue mixing device to store a kind of liquid through the second glue bucket 520, and enables the staff to open and close the second valve 540 to adjust whether the liquid in the second glue bucket 520 flows into the second discharge channel 120.
[0059] Please refer to Figure 6 As shown, further, among which Figure 6 Only the second vacuum pump interface 560 for connecting the second vacuum pump is shown. In some embodiments, the storage mechanism 500 further includes a second vacuum pump. The second vacuum pump is communicated with the second accommodating cavity through the second vacuum pump interface 560 and is used to extract the air in the second accommodating cavity when the second valve 540 cuts off the connection between the second accommodating cavity and the second discharge channel 120. When the second valve 540 is cut off, the second vacuum pump can extract the air in the second accommodating cavity and reduce the air content in the second accommodating cavity. Then, when the second valve 540 is opened, the air content in the liquid in the second accommodating cavity is lower, and it is less likely to generate bubbles inside after mixing with the liquid in the first discharge channel 110, thereby improving the quality of the glue.
[0060] On the premise of not departing from the inventive concept of the present invention, in some embodiments, the storage mechanism 500 includes a first glue bucket 510, a first valve 530, a first vacuum pump, a second glue bucket 520, a second valve 540 and a second vacuum pump at the same time.
[0061] Further, please refer to Figure 1 、 Figure 7As shown, in some embodiments, the glue mixing device further includes a waste discharging mechanism 600. The waste discharging mechanism 600 includes a bubble sensor, a bubble detection pipeline 610, and a three-way valve 620. The bubble detection pipeline 610 includes a detection pipeline 611, an output pipeline 612, and a waste discharging pipeline 613. The detection pipeline 611 has a detection channel 614, the output pipeline 612 has an output channel 615, and the waste discharging pipeline 613 has a waste discharging channel 616. One end of the detection channel 614, one end of the output channel 615, and one end of the waste discharging channel 616 are connected through the three-way valve 620. The other end of the detection channel 614 is connected to the mixing channel 130. The output channel 615 is for discharging glue. The bubble sensor is located outside the bubble detection pipeline 610 to detect the bubbles in the liquid in the detection channel 614. The bubble sensor is signal-connected to the three-way valve 620. The three-way valve 620 connects the detection channel 614 and the waste discharging channel 616 when the bubble sensor detects bubbles, and connects the detection channel 614 and the output channel 615 when the bubble sensor does not detect bubbles. When the bubble sensor detects bubbles in the glue, the three-way valve 620 connects the detection channel 614 and the waste discharging channel 616, so that the glue with bubbles in the detection channel 614 is transported to the waste discharging channel 616. When the bubble sensor detects bubbles in the glue, the three-way valve 620 connects the detection channel 614 and the output end, so that the glue without bubbles enters the output channel 615. The above solution can realize the quality detection function of the glue mixing device, avoid using the glue with bubbles for small parts, and thus ensure the glue coating quality.
[0062] In some embodiments, the bubble sensor is an ultrasonic bubble sensor. The ultrasonic bubble sensor is divided into an ultrasonic transmitter and an ultrasonic receiver. Both the ultrasonic transmitter and the ultrasonic receiver are attached to the outside of the bubble detection channel 614 and are located at opposite ends. The ultrasonic transmitter continuously emits ultrasonic waves into the detection channel 614. When there are no bubbles in the glue in the detection channel 614, the ultrasonic waves can pass through the detection channel 614 and be received by the ultrasonic receiver. The three-way valve 620 connects the detection channel 614 and the conveying section according to the behavior that the ultrasonic receiver receives the ultrasonic waves, so that the glue without bubbles enters the output channel 615. When there are bubbles in the glue in the detection channel 614, the ultrasonic waves cannot pass through the detection channel 614, and the ultrasonic receiver cannot receive the ultrasonic waves. The three-way valve 620 connects the detection channel 614 and the conveying section according to the behavior that the ultrasonic receiver does not receive the ultrasonic waves, so that the glue with bubbles enters the output channel 615.
[0063] Further, in some embodiments, the waste discharging mechanism 600 further includes a collection bin 630. The collection bin 630 is placed below the bubble detection pipeline 610 and has a collection chamber. The collection chamber has an opening 640. The opening 640 of the collection chamber faces upward and is located below the end opening of the waste discharging channel 616. When the glue with bubbles enters the opening of the waste discharging channel 616, it will fall into the collection chamber automatically due to the gravity traction, so that the waste discharging channel 616 can receive new glue with bubbles.
[0064] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present utility model within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
