[0058] Research has found that the dispensing head of existing dispensing equipment is prone to clogging during use, requiring manual disassembly and cleaning of the dispensing head, which affects the overall dispensing efficiency.
[0059] Based on the above research, this disclosure provides a dispensing device and a dispensing head unblocking mechanism, including but not limited to applications on a glue dispensing machine. By providing an unblocking component, when the dispensing head becomes clogged during operation, the dispensing head is moved to engage with the unblocking component, and when the dispensing head is reset, the unblocking component removes the glue clogging the dispensing head to achieve unblocking.
[0060] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0061] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0062] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0063] In some embodiments, such as Figure 1 As shown, during normal operation, the rotary motor 45 is started, and its output end drives the lead screw 46 to rotate, which in turn drives the moving part 40, which meshes with the lead screw 46, to move along the axis of the lead screw 46. The moving part 40 is equipped with a cylinder 48, and the output end 49 of the cylinder is connected to the bottom of the rotary driver 41. The cylinder drives the rotary driver 41 and its components to move vertically. When a blockage occurs, the rotary driver 41 drives the dispensing head 30 to rotate to the waste glue collection box 24, and then retracts it through the cylinder, so as to move the dispensing head 30 down into the waste glue collection box 24 to clear the blockage.
[0064] As another embodiment, the movement of the dispensing head 30 may include, but is not limited to, using a three-axis kinetic pair drive.
[0065] The top of the dispensing head 30 is connected to the dispensing pump device, which is an existing device, and the connection between the dispensing pump device and the dispensing head 30 is existing technology, which will not be described in detail here. Preferably, a sensor can be installed in the dispensing head 30 to detect the flow of glue in the dispensing head 30. When the sensor detects that the glue has stopped flowing, the control module controls the dispensing pump device to stop pumping glue, and at the same time controls the moving part 40 to move to the side of the waste glue collection box 24. The rotary driver 41 is started to drive the rotating shaft 42 to rotate. The dispensing head 30 is moved above the unblocking part 20 through the connecting part 43, so that the axis of the dispensing head 30 is collinear with the axis of the unblocking part 20. The cylinder 48 drives the dispensing head 30 to move down and insert it into the unblocking part 20 to unblock the dispensing head 30.
[0066] In some embodiments, such as Figure 2As shown, the dispensing head 30 moves along the F1 direction to be inserted into the unblocking component 20. The cross-section of the unblocking component 20 is preferably conical. After the unblocking component 20 is inserted into the glue inside the dispensing head 30, as the dispensing head 30 is reset, the lower end face of the unblocking component 20 pulls the blocked glue away from the dispensing head 30 to unblock the dispensing head 30.
[0067] like Figure 3 As shown, a combination spring is installed inside the unclogging bottom cylinder 22. When the unclogging part 20 is inserted into the glue inside the dispensing head 30, as the dispensing head 30 resets along the F2 direction, the unclogging part 20 will be moved upward because the glue that is blocking it wraps around it. At this time, the unclogging part 20 will move the threaded rod 21. Since the threaded rod 21 is engaged with the thread on the inner wall of the unclogging bottom cylinder 22, the unclogging part 20 and the threaded rod 21 are in a state of rotation and upward movement. The unclogging groove opened on the surface of the unclogging part 20 will twist the glue that is blocking the dispensing head 30, which will further improve the effect of removing the blockage. After the dispensing head 30 and the unclogging part 20 are separated, the threaded rod 21 will be rotated and reset by gravity.
[0068] Furthermore, a combined spring 23 can be installed inside the bottom tube 22, and the combined spring 23 is connected to the bottom of the threaded rod 21 to promote the reset of the threaded rod 21.
[0069] In some embodiments, such as Figure 4 As shown, one end of each of the two clamping members 31 is connected to the connector 32 by a bearing, meaning that both clamping members 31 can rotate freely around the connection point with the connector 32. Several arc-shaped notches 33 are symmetrically provided on the opposite side of the two clamping members 31. The radius of each arc-shaped notch 33 is designed to follow the diameter of the dispensing head 30 to be clamped, thereby adapting to dispensing heads 30 of different diameters. The dispensing head 30 is placed in the arc-shaped notch 33 and the two clamping members 31 are manually closed to clamp the dispensing head 30. Then, the two clamping members 31 are connected by bolts 35 and locked with matching nuts. The connection direction between the connector 32 and the connector 43 includes, but is not limited to, the form of plugging.
[0070] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0071] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0072] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0073] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0074] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
