[0062] The following detailed description is illustrative and non-limiting. It is intended to provide a basic understanding of the present application and is not intended to identify the key or decisive elements of the present application or to limit the scope of protection. As long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any manner.

[0063] When a component is referred to as being “disposed on” another component, it can be directly disposed on the other component or there may be a component intervening therebetween. When a component is referred to as being “connected to” another component, it can be directly connected to the other component or there may be a component intervening therebetween.

[0064] It can be understood that the term "perpendicular" is used to describe the ideal state between two components. In actual production or use, there may be a state between the two components that is approximately perpendicular or equal. For example, combined with numerical descriptions, perpendicular can refer to the angle between two straight lines being in the range of 90°±10°, perpendicular can also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicular can also refer to the angle between a straight line and a plane being in the range of 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0065] Unless otherwise defined, the term "plurality" herein, when used to describe the number of components, specifically means that the components are two or more.

[0066] An embodiment of the present application provides a dispensing device, comprising a conveying mechanism, a positioning mechanism, a lifting mechanism, a visual mechanism and a dispensing mechanism. The conveying mechanism is used to convey a carrier plate, in which a workpiece is placed, and the workpiece includes a connecting hole. The positioning mechanism is located above the conveying mechanism. The lifting mechanism is located in the conveying direction of the conveying mechanism, and is used to lift the carrier plate, so that the carrier plate is separated from the conveying mechanism, and the workpiece abuts the positioning mechanism. The visual mechanism is located above the conveying mechanism, and is used to photograph the position of the connecting hole. The dispensing mechanism is located above the conveying mechanism, and is used to dispense glue to the connecting hole according to the position of the connecting hole. By cooperating with the conveying mechanism, the positioning mechanism and the lifting mechanism to locate the position of the workpiece, the accuracy of the visual mechanism in photographing the position of the connecting hole is improved, thereby improving the dispensing efficiency and dispensing accuracy of the dispensing mechanism.

[0067] Some embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0068] See also Figure 1 and Figure 2 In one embodiment of the present application, a dispensing device 100 is provided, comprising a conveying mechanism 10, a positioning mechanism 20, and a lifting mechanism 30. The conveying mechanism 10 is used to convey a carrier 200, in which a workpiece 201 is placed, and the workpiece 201 includes a connecting hole 201a. The positioning mechanism 20 is located above the conveying mechanism 10. The lifting mechanism 30 is located in the conveying direction of the conveying mechanism 10 and is used to lift the carrier 200, so that the carrier 200 is separated from the conveying mechanism 10, and the workpiece 201 abuts against the positioning mechanism 20.

[0069] In some embodiments, the dispensing device 100 includes a vision mechanism 40 and a dispensing mechanism 50. The vision mechanism 40 is located above the conveying mechanism 10 and is used to capture the position of the connecting hole 201a. The dispensing mechanism 50 is located above the conveying mechanism 10 and is used to dispense glue to the connecting hole 201a based on the position of the connecting hole 201a.

[0070] This application uses the conveying mechanism 10, the positioning mechanism 20 and the lifting mechanism 30 to coordinate and locate the position of the workpiece 201, thereby improving the accuracy of the visual mechanism 40 in photographing the position of the connecting hole 201a, and thereby improving the dispensing efficiency and dispensing accuracy of the dispensing mechanism 50.

[0071] In some embodiments, the conveyor mechanism 10 includes a conveyor support 11, a conveyor belt 12, and a conveyor drive 13. The conveyor belt 12 is looped around the conveyor support 11. The conveyor drive 13 is connected to the conveyor belt 12, driving the conveyor belt 12 to rotate, thereby driving the carrier 200 to move along the conveyor belt 12 along a first direction X. The first direction X is the conveying direction of the conveyor mechanism 10.

[0072] In some embodiments, the dispensing device 100 includes a base 101 , and the conveying bracket 11 is fixed to the base 101 .

[0073] See also Figure 1 and Figure 2 In some embodiments, the positioning mechanism 20 includes a bracket 21 and a positioning block 22 . The bracket 21 is mounted above the conveying mechanism 10 . The positioning block 22 is fixed to a side of the bracket 21 facing the conveying mechanism 10 for abutting the workpiece 201 .

[0074] In some embodiments, the bracket 21 is fixedly connected to the base 101 .

[0075] In some embodiments, a plurality of positioning blocks 22 are provided, and the plurality of positioning blocks 22 are spaced apart along the second direction Y, thereby improving the stability of the workpiece 201 in the carrier 200 and facilitating improving the accuracy of positioning the workpiece 201 .

[0076] In some embodiments, the carrier 200 is a flexible structure, and the workpiece 201 includes a first surface 201b facing away from the carrier 200. The positioning block 22 is configured to abut against the first surface 201b. Using the first surface 201b as a positioning reference in the third direction Z prevents deformation of the carrier 200 from causing a change in the distance between the vision mechanism 40 and the workpiece 201 in the third direction Z, which could lead to unclear images and affect the accuracy of the position of the connecting hole 201a, as well as the compensation effect when the vision mechanism 40 is moved. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0077] See also Figure 1 and Figure 3 In some embodiments, the lifting mechanism 30 includes a lifting drive member 31, a connecting plate 32 and two lifting plates 33. The lifting drive member 31 is fixedly connected to the base 101. The connecting plate 32 is connected to the lifting drive member 31, and the connecting plate 32 is arranged in the annular structure of the conveyor belt 12. The lifting plate 33 is connected to the connecting plate 32. Along the second direction Y, the conveyor belt 12 is located between the two lifting plates 33. The lifting drive member 31 drives the connecting plate 32 to rise, and the connecting plate 32 drives the two lifting plates 33 to protrude from the conveyor belt 12 along the third direction Z, thereby lifting the carrier 200 and making the positioning block 22 abut against the first surface 201b. The lifting drive member 31 drives the connecting plate 32 to descend, and the connecting plate 32 drives the two lifting plates 33 to move to a position lower than the conveyor belt 12, so that the carrier 200 contacts and connects to the conveyor belt 12, and continues to drive the carrier 200 to move along the first direction X through the conveyor belt 12.

[0078] In some embodiments, the dispensing device 100 includes a first limiter 60 and a positioning member 70 . The first limiter 60 is used to limit the position of the carrier 200 along the first direction X, and the positioning member 70 is used to position the carrier 200 along the second direction Y.

[0079] In some embodiments, the first limiting member 60 includes a first limiting driver 61 and a first limiting block 62. The first limiting driver 61 is fixed to the base 101, and the first limiting block 62 is connected to the first limiting driver 61. The first limiting driver 61 drives the first limiting block 62 to rise, preventing the carrier 200 from moving on the conveyor belt 12 and positioning the carrier 200 above the lifting plate 33.

[0080] In some embodiments, the positioning member 70 includes a positioning driver 71 and a positioning plate 72. The positioning driver 71 is fixed to one side of the conveying bracket 11 along the second direction Y, and the positioning plate 72 is connected to the positioning driver 71. The positioning driver 71 drives the positioning plate 72 to move along the second direction Y. The positioning plate 72 pushes one side of the carrier 200 so that the other side of the carrier 200 abuts the conveying bracket 11, thereby positioning the carrier 200 in the second direction Y.

[0081] In some embodiments, the dispensing device 100 includes a second limiter 80 , which is fixed to the base 101 . Along the first direction X, the lifting mechanism 30 is located between the first limiter 60 and the second limiter 80 .

[0082] In some embodiments, the second limiting member 80 includes a second limiting driver 81 and a second limiting block 82. The second limiting driver 81 is fixed to the base 101, and the second limiting block 82 is connected to the second limiting driver 81. The second limiting driver 81 drives the first limiting block 62 to rise, preventing the subsequent carrier 200 from moving above the lifting plate 33.

[0083] In some embodiments, the dispensing device 100 includes an adsorption member 102, which is connected to the lifting plate 33 and is used to adsorb the carrier 200 on the lifting plate 33. When the positioning block 22 abuts the first surface 201b, the stability of the carrier 200 on the lifting plate 33 is improved, which is beneficial to improving the accuracy of the position of the connecting hole 201a captured by the visual mechanism 40, thereby improving the dispensing efficiency and dispensing accuracy of the dispensing mechanism 50.

[0084] In some embodiments, the dispensing device 100 includes a sensor disposed on the base 101 for sensing the position of the carrier 200. When the sensor senses the carrier 200, the first limit drive 61 drives the first limit block 62 to rise, preventing the carrier 200 from moving on the conveyor belt 12.

[0085] See also Figure 1In some embodiments, the dispensing device 100 includes a moving mechanism 90 located above the conveying mechanism 10, the visual mechanism 40 and the dispensing mechanism 50 are connected to the moving mechanism 90, and the moving mechanism 90 drives the visual mechanism 40 and the dispensing mechanism 50 to move along the first direction X, the second direction Y and the third direction Z.

[0086] In some embodiments, the moving mechanism 90 includes a first moving member 91, a second moving member 92 and a third moving member 93, the second moving member 92 connects the first moving member 91 and the third moving member 93, the first moving member 91 drives the second moving member 92 and the third moving member 93 to move along the first direction X, the second moving member 92 drives the third moving member 93 to move along the second direction Y, and the third moving member 93 connects the visual mechanism 40 and the dispensing mechanism 50, and is used to drive the visual mechanism 40 and the dispensing mechanism 50 to move along the third direction Z.

[0087] See also Figure 4 In some embodiments, the visual mechanism 40 includes an adjusting bracket 41 and a camera element 42. The adjusting bracket 41 is fixedly connected to the third movable member 93, and the camera element 42 is connected to the adjusting bracket 41. The adjusting bracket 41 is used to adjust the distance between the camera element 42 and the workpiece 201 along the third direction Z, which is conducive to clearly capturing the position of the connecting hole 201a.

[0088] In some embodiments, the camera 42 is further used to photograph the glue condition in the connection hole 201 a and detect whether the glue is located at the glue dispensing position.

[0089] In some embodiments, the camera 42 is also used to capture the number of the carrier 200 or the workpiece 201. When the glue detected by the camera 42 is not at the dispensing position, the control system of the dispensing device 100 records the corresponding number, so as to find the workpiece 201 that does not meet the requirements after the carrier 200 flows into the next workstation.

[0090] In some embodiments, the adjustment bracket 41 includes a fixed plate 411 and a sliding member 412 . The fixed plate 411 is fixedly connected to the third movable member 93 . The sliding member 412 is slidably connected to the fixed plate 411 . The camera 42 is fixedly connected to the sliding member 412 .

[0091] In some embodiments, the dispensing mechanism 50 includes a fixed bracket 51 and a dispensing member 52 . The fixed bracket 51 is fixed to the third movable member 93 , and the dispensing member 52 is fixed to the fixed bracket 51 .

[0092] In some embodiments, the dispensing device 100 includes two conveying mechanisms 10 arranged along the second direction Y, and both conveying mechanisms 10 are used to convey the carrier 200. When the camera 42 and the dispensing component 52 are photographing and dispensing the workpiece 201 on the carrier 200 of one conveying mechanism 10, the lifting mechanism 30, the first limiter 60, and the positioning component 70 are positioning the workpiece 201 on the carrier 200 of the other conveying mechanism 10. This alternating operation is beneficial to improving dispensing efficiency.

[0093] When the above-mentioned dispensing device 100 is in use, the carrier 200 of the previous workstation is first moved through the conveyor belt 12, the first limit driving component 61 drives the first limit block 62 to rise, blocking the carrier 200 from moving on the conveyor belt 12, and making the carrier 200 located above the lifting plate 33, the second limit driving component 81 drives the first limit block 62 to rise, blocking the subsequent carrier 200 from moving above the lifting plate 33. The positioning drive 71 drives the positioning plate 72 to move in the second direction Y. The positioning plate 72 pushes one side of the carrier 200, causing the other side of the carrier 200 to abut against the conveyor bracket 11, positioning the carrier 200 in the second direction Y. The suction element 102 adsorbs the carrier 200 onto the lifting plate 33. The lifting drive 31 drives the connecting plate 32 upward. The connecting plate 32 drives the two lifting plates 33 to protrude from the conveyor belt 12 in the third direction Z, raising the carrier 200 and causing the positioning block 22 to abut against the first surface 201b. The camera 42 captures the position of the connecting hole 201a. The glue dispensing component 52 dispenses glue into the connecting hole 201a based on the position of the connecting hole 201a. The camera 42 captures the glue in the connecting hole 201a to detect whether the glue is at the dispensing position. When the glue is at the dispensing position, the first limit drive 61 drives the first limit block 62 downward, and the carrier 200 moves to the next workstation on the conveyor belt 12.

[0094] This application uses the conveying mechanism 10, the positioning mechanism 20 and the lifting mechanism 30 to coordinate and locate the position of the workpiece 201, thereby improving the accuracy of the visual mechanism 40 in photographing the position of the connecting hole 201a, and thereby improving the dispensing efficiency and dispensing accuracy of the dispensing mechanism 50.

[0095] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments fall within the scope disclosed in the present application.
