When dealing with workpieces requiring simultaneous multi-point and multi-line coating, this type of equipment must complete the task through repeated movement and dispensing actions, resulting in low production efficiency. Utility Model Content
[0003] Therefore, it is necessary to provide a dispensing mechanism and dispensing machine that can improve dispensing efficiency.
[0004] A glue-separating mechanism, comprising: Connector, the connector having an adhesive inlet; and The glue dispensing seat is connected to the connecting seat. The glue dispensing seat includes a main glue channel and a plurality of dispensing channels that communicate with the main glue channel. The glue inlet is connected to the main glue channel, and each of the dispensing channels has a glue outlet protruding outward at its outlet position. The spacing between the dispensing nozzles is adjustable; and / or, the dispensing base has multiple types, each with a different dispensing channel distribution pattern, and the connecting base can be selectively and detachably connected to the dispensing base of different types.
[0005] In one embodiment, the dispensing base includes multiple dispensing bases, and the connecting base is sequentially connected to the multiple dispensing bases along the height direction of the dispensing mechanism. The main glue channel of one dispensing base is connected to the main glue channel and each of the dispensing channels of the adjacent dispensing base. The glue inlet is connected to the main glue channel of the dispensing base closest to the connecting base. The dispensing nozzle is provided outwardly at the outlet position of each of the dispensing channels of the dispensing base farthest from the connecting base.
[0006] In one embodiment, all of the glue-separating seats are of the same type or at least two of the glue-separating seats are of different types.
[0007] In one embodiment, the connecting seat is provided with a first connecting hole, the glue separating seat is provided with a second connecting hole, and the glue separating mechanism further includes a fastener for passing through the first connecting hole and the second connecting hole to fix the connecting seat and the glue separating seat.
[0008] A dispensing machine includes: a glue supply mechanism and the aforementioned glue dispensing mechanism, wherein the glue supply mechanism is connected to the connecting seat, and the dispensing head of the glue supply mechanism is in communication with the glue inlet of the connecting seat.
[0009] In one embodiment, the glue supply mechanism further includes a screw valve connected to the dispensing head, the screw valve being used to control the flow rate and timing of the glue output from the dispensing head.
[0010] In one embodiment, the glue supply mechanism and the glue dispensing mechanism together constitute a dispensing mechanism. The dispensing machine further includes an X motion platform, a Y motion platform, and a Z motion platform. The dispensing mechanism is connected to the Z motion platform, the Z motion platform is connected to the X motion platform, and the X motion platform is connected to the Y motion platform. The X motion platform is used to drive the dispensing mechanism to move along the X direction, the Y motion platform is used to drive the dispensing mechanism to move along the Y direction, and the Z motion platform is used to drive the dispensing mechanism to move along the Z direction.
[0011] In one embodiment, the dispensing machine further includes a detection module connected to the dispensing mechanism. The detection module is used to detect the three-dimensional coordinate information of the preset dispensing points on the dispensing workpiece in the X, Y, and Z directions.
[0012] In one embodiment, the detection module includes a contact detector or a non-detection detector, wherein the non-detection detector includes any one of a laser displacement sensor, an ultrasonic detection head, and a 3D vision sensor.
[0013] In one embodiment, the dispensing machine further includes an industrial control computer, which is communicatively connected to the X motion platform, the Y motion platform, the Z motion platform, the detection module, and the dispensing mechanism. The industrial control computer is used to compare the actual coordinate value of the preset dispensing point in the Z direction detected by the detection module with the preset theoretical coordinate value in the Z direction of the preset dispensing point, and calculate the height deviation value of the preset dispensing point in the Z direction. The industrial control computer is also used to calculate the compensation displacement in the Z direction of the preset dispensing point based on the height deviation value in the Z direction of the preset dispensing point and the preset ideal gap between the dispensing mechanism and the dispensing workpiece in the Z direction. The industrial control computer is also used to control the X motion platform, the Y motion platform, and the Z motion platform to move the dispensing mechanism along the X, Y, and Z directions respectively, based on the three-dimensional coordinate information of the preset dispensing point and the compensation displacement in the Z direction of the preset dispensing point, so that the dispensing mechanism can perform dispensing operations on the preset dispensing point.
[0014] The dispensing mechanism provided in this application has a main dispensing channel and multiple dispensing channels connected to the main dispensing channel. The inlet of the connecting seat is connected to the main dispensing channel, and each dispensing channel has a dispensing nozzle protruding outward at its outlet. Thus, when a user injects a single stream of glue into the inlet of the connecting seat, the single stream injected into the inlet can be diverted to multiple dispensing nozzles through the combined diversion effect of the main dispensing channel and multiple dispensing channels, achieving simultaneous dispensing at multiple points. This effectively improves dispensing efficiency and overcomes the low efficiency of single-nozzle dispensing, meeting the high-cycle requirements of modern production lines. In addition, since the spacing between the dispensing nozzles in this application is adjustable, and / or the dispensing seat has multiple types with different dispensing channel distribution patterns, the connecting seat can be selectively and detachably connected to different types of dispensing seats. This allows the dispensing mechanism to flexibly adjust the spacing between the dispensing nozzles and / or select different types of dispensing seats according to actual dispensing needs, adapting to the dispensing position layout of different dispensing workpieces, greatly expanding the applicability of the dispensing mechanism.

[0020] like Figure 1 and Figure 2 As shown, this application provides a glue dispensing mechanism 100, which includes a connecting seat 110 and a glue dispensing seat 120. The connecting seat 110 has a glue inlet 111. The glue dispensing seat 120 is connected to the connecting seat 110 and includes a main glue channel 121 and a plurality of glue dispensing channels 122 communicating with the main glue channel 121. The glue inlet 111 is communicating with the main glue channel 121. Each glue dispensing channel 122 has a glue outlet 123 protruding outward at its outlet position. The spacing between the glue outlets 123 is adjustable. And / or, the glue dispensing seat 120 has multiple types, and different types of glue dispensing seats 120 have different glue channel distribution patterns. The connecting seat 110 can be selectively and detachably connected to different types of glue dispensing seats 120.
[0021] The dispensing mechanism 100 provided in this application includes a dispensing base 120 having a main dispensing channel 121 and multiple dispensing channels 122 connected to the main dispensing channel 121. The inlet 111 of the connecting base 110 is connected to the main dispensing channel 121. Each dispensing channel 122 has a protruding nozzle 123 at its outlet. Thus, when a user injects a single stream of glue into the inlet 111 of the connecting base 110, the single stream injected into the inlet 111 can be diverted to multiple nozzles 123 through the combined diversion effect of the main dispensing channel 121 and the multiple dispensing channels 122, achieving simultaneous dispensing at multiple points. This effectively improves dispensing efficiency and overcomes the limitations of single-nozzle dispensing. The low dispensing efficiency of this device meets the high-speed requirements of modern production lines. Furthermore, the spacing between the dispensing nozzles 123 is adjustable, and / or the dispensing base 120 has various types with different dispensing channel distributions. The connecting seat 110 can be selectively and detachably connected to different types of dispensing bases 120, allowing the dispensing mechanism 100 to flexibly adjust the spacing between the dispensing nozzles 123 and / or select different types of dispensing bases 120 according to actual dispensing needs. This adapts to the dispensing layout of different dispensing workpieces, greatly expanding the applicability of the dispensing mechanism 100.
[0022] Specifically, the connecting seat 110 has a square structure, and an inlet 111 is provided in the middle of the connecting seat 110. Further, the dispensing seat 120 can also have a square structure. Multiple dispensing seats 120 are included, and the connecting seat 110 and the multiple dispensing seats 120 are sequentially connected along the height direction of the dispensing mechanism 100. The main glue channel 121 of one dispensing seat 120 is connected to the main glue channel 121 and each dispensing channel 122 of the adjacent dispensing seat 120. The inlet 111 is connected to the main glue channel 121 of the dispensing seat 120 closest to the connecting seat 110. The outlet positions of each dispensing channel 122 of the dispensing seat 120 furthest from the connecting seat 110 have outwardly protruding glue nozzles 123. All dispensing seats 120 are of the same type, or at least two dispensing seats 120 are of different types.
[0023] like Figure 1 As shown, in this embodiment, the glue dispensing mechanism 100 includes a first glue dispensing seat 124. The first glue dispensing seat 124 includes a main glue channel 121 and four glue dispensing channels 122 connected to the main glue channel 121. The main glue channel 121 is located in the middle of the first glue dispensing seat 124 and has a circular cross-section. The four glue dispensing channels 122 are spaced around the main glue channel 121. Both the main glue channel 121 and the glue dispensing channels 122 extend along the height direction of the glue dispensing mechanism 100. The length of the main glue channel 121 in the height direction of the glue dispensing mechanism 100 and the length of each glue dispensing channel 122 in the height direction of the glue dispensing mechanism 100 are equal, and the distance from the center of each glue dispensing channel 122 to the center of the main glue channel 121 is equal.
[0024] Furthermore, the dispensing mechanism 100 also includes a second dispensing seat 125. The connecting seat 110 is sequentially connected to the first dispensing seat 124 and the second dispensing seat 125 along the height direction of the dispensing mechanism 100. The second dispensing seat 125 includes a main dispensing channel 121 and eight dispensing channels 122 connected to the main dispensing channel 121. The main dispensing channel 121 is located in the middle of the second dispensing seat 125, and the eight dispensing channels 122 are spaced apart on the bottom wall of the main dispensing channel 121. Specifically, the inlet 111 of the connecting seat 110 is connected to the main dispensing channel 121 of the first dispensing seat 124, and each dispensing channel 122 of the second dispensing seat 125 has an outlet nozzle 123 protruding outward. Specifically, the orifice size of each dispensing channel is the same, so that uniform dispensing can be achieved under pressure, thereby achieving synchronous, precise, and uniform dispensing from multiple dispensing points and ensuring product consistency.
[0025] Furthermore, the dispensing nozzles 123 can be of a uniform specification to facilitate mass production and easy replacement. The dispensing nozzles 123 are detachably installed at the outlet of the dispensing channel 122, so if individual dispensing nozzles 123 are damaged or blocked, only one dispensing nozzle 123 needs to be replaced, resulting in low maintenance costs and easy cleaning.
[0026] like Figure 1 As shown, the connecting seat 110 is further provided with a first connecting hole 112, and the dispensing seat 120 is provided with a second connecting hole 126. The dispensing mechanism 100 also includes fasteners, which may be, but are not limited to, threaded fasteners. The fasteners are used to pass through the first connecting hole 112 and the second connecting hole 126 to fix the connecting seat 110 and the dispensing seat 120. Specifically, the four corners of the connecting seat 110 are provided with first connecting holes 112 for the fasteners to pass through, and the four corners of each dispensing seat 120 are provided with second connecting holes 126 for the fasteners to pass through, so as to facilitate a stable fixed connection between the connecting seat 110 and each dispensing seat 120.
[0027] like Figure 3 and Figure 4 As shown, this application also provides a dispensing machine for dispensing adhesive to workpieces. The dispensing machine includes a glue supply mechanism 200 and the aforementioned glue dispensing mechanism 100. The glue supply mechanism 200 is connected to a connecting base 110, and the dispensing head 210 of the glue supply mechanism 200 communicates with the glue inlet 111 of the connecting base 110. It should be noted that, in this embodiment, the workpiece to be dispensed can specifically be a chip or a PCB board, etc.
[0028] Furthermore, the glue supply mechanism 200 also includes a screw valve 220, which is connected to the dispensing head 210. The screw valve 220 is used to control the flow rate and dispensing timing of the glue output from the dispensing head 210. Specifically, the screw valve 220 is precisely driven by a servo motor to rotate its rotor. Its core function is to control the flow rate and dispensing timing of the glue output from the dispensing head 210 with extremely high repeatability, thus preventing dripping and stringing from occurring at the dispensing head 210.
[0029] like Figure 4 As shown, the glue supply mechanism 200 further includes a glue tank 230, which is connected to the dispensing head 210 via a pipeline. The glue stored in the glue tank 230 can be dispensed to the dispensing head 210. Furthermore, the glue tank 230 is used to receive a compressed air source, which provides power to the entire glue supply mechanism 200, so that the glue in the glue tank 230 can be smoothly dispensed to the dispensing head 210 through the pressurization effect of the compressed air source.
[0030] like Figure 5 and Figure 6 As shown, the glue supply mechanism 200 and the glue dispensing mechanism 100 together constitute the dispensing mechanism 10. The dispensing machine also includes an X motion platform 20, a Y motion platform 30 and a Z motion platform 40. The dispensing mechanism 10 is connected to the Z motion platform 40, the Z motion platform 40 is connected to the X motion platform 20, and the X motion platform 20 is connected to the Y motion platform 30. The X motion platform 20 is used to drive the dispensing mechanism 10 to move in the X direction, the Y motion platform 30 is used to drive the dispensing mechanism 10 to move in the Y direction, and the Z motion platform 40 is used to drive the dispensing mechanism 10 to move in the Z direction.
[0031] Specifically, the X motion platform 20, Y motion platform 30 and Z motion platform 40 together constitute a three-axis (XYZ) motion platform, which is responsible for driving the entire dispensing mechanism 10 to move along a preset trajectory. Among them, the Z motion platform 40 undertakes the key task of controlling the dispensing mechanism 10 to precisely lift or lower along the Z direction according to the compensation command. The specific details will be described in detail later.
[0032] Furthermore, the aforementioned dispensing machine also includes a detection module 50, which is connected to the dispensing mechanism 10. The detection module 50 is used to detect the three-dimensional coordinate information of the preset dispensing points on the workpiece in the X, Y, and Z directions. Specifically, the detection module 50 can be fixedly installed on one side of the dispensing mechanism 10, and its core function is to detect the three-dimensional coordinate information of each preset dispensing point on the workpiece in the X, Y, and Z directions before dispensing.
[0033] Furthermore, the detection module 50 includes a contact detector or a non-detection detector, wherein the non-detection detector includes any one of a laser displacement sensor, an ultrasonic detection head, and a 3D vision sensor.
[0034] Specifically, when the detection module 50 uses a laser displacement sensor, the spot position of the laser displacement sensor coincides with or has a fixed mapping relationship with the working point position of the dispensing mechanism 10 in the XY plane. Its core function is to non-contactly measure the three-dimensional coordinate information of each preset dispensing point on the dispensing workpiece in the X, Y, and Z directions before dispensing. Specifically, before dispensing, the X motion platform 20, Y motion platform 30, and Z motion platform 40 can respectively drive the laser displacement sensor to move along the X, Y, and Z directions, so that the laser displacement sensor can move above each preset dispensing point on the dispensing workpiece, thereby collecting and recording the coordinate information of each preset dispensing point on the dispensing workpiece in the X, Y, and Z directions.
[0035] Furthermore, the aforementioned dispensing machine also includes an industrial control computer, which is communicatively connected to the X motion platform 20, Y motion platform 30, Z motion platform 40, detection module 50, and dispensing mechanism 10. The industrial control computer integrates a motion control card, PLC, vision processing module, and human-machine interface. It is not only the command center but also the data processing and compensation center, responsible for receiving data collected by the detection module 50 and coordinating the three-axis (XYZ) motion platform and dispensing mechanism 10 in real time.
[0036] It should be noted that existing dispensing equipment typically assumes the surface of the workpiece to be dispensed is flat, or dispenses adhesive at a preset fixed height. However, in actual production, due to PCB warping, inconsistent component heights, or fixture errors, the actual height of the dispensing position varies, causing changes in the gap (height) between the nozzle and the workpiece. This severely affects the shape, size, and consistency of the adhesive dots, and may even lead to nozzle collisions or stringing.
[0037] To address the aforementioned problems, the dispensing machine of this application has the following improvements, specifically: The industrial control computer is used to compare the actual coordinate value of the preset dispensing point in the Z direction detected by the detection module 50 with the preset theoretical coordinate value in the Z direction of the preset dispensing point, and calculate the height deviation value of the preset dispensing point in the Z direction. The industrial control computer is also used to calculate the compensation displacement of the preset dispensing point in the Z direction based on the height deviation value of the preset dispensing point in the Z direction and the preset ideal gap between the dispensing mechanism 10 and the dispensing workpiece in the Z direction. The industrial control computer is also used to control the X motion platform 20, Y motion platform 30 and Z motion platform 40 to drive the dispensing mechanism 10 to move along the X direction, Y direction and Z direction respectively, so that the dispensing mechanism 10 performs dispensing operation on the preset dispensing point.
[0038] Specifically, the working principle of the dispensing machine in this application is as follows: (1) Measurement and scanning stage: Before the dispensing action begins, the industrial control computer controls the X motion platform 20, Y motion platform 30 and Z motion platform 40 to drive the detection module 50 to move along the X direction, Y direction and Z direction respectively, so that the detection module 50 can move above each preset dispensing point on the dispensing workpiece, thereby collecting and recording the coordinate information of each preset dispensing point on the dispensing workpiece in the X direction, Y direction and Z direction.
[0039] (2) System compensation calculation: The industrial control computer compares the actual coordinate value of the preset dispensing point in the Z direction detected by the detection module 50 with the preset theoretical coordinate value in the Z direction of the preset dispensing point, calculates the height deviation value in the Z direction of the preset dispensing point, and then calculates the compensation displacement in the Z direction of the preset dispensing point based on the height deviation value in the Z direction of the preset dispensing point and the preset ideal gap between the dispensing mechanism 10 and the dispensing workpiece in the Z direction.
[0040] (3) Adaptive dispensing execution: At the beginning of the dispensing process, the industrial control computer not only controls the X motion platform 20 and the Y motion platform 30 to drive the dispensing mechanism 10 to move along the preset X and Y directions (i.e., the dispensing coordinates in the X and Y directions when the dispensing mechanism 10 is aligned with the preset dispensing point on the dispensing workpiece), but also controls the Z motion platform 40 to drive the dispensing mechanism 10 to move up and down in the Z direction in real time according to the dispensing coordinates in the Z direction of the preset dispensing point and the compensation displacement in the Z direction of the preset dispensing point. This ensures that the gap between the dispensing mechanism 10 and the dispensing workpiece in the Z direction remains constant under any surface undulation. Under this stable gap, the screw valve 220 controls the dispensing head 210 to dispense glue, thereby ensuring that the shape, size and tearing effect of each glue dot on the dispensing workpiece are highly consistent.
[0041] Therefore, the dispensing machine of this application has at least the following beneficial effects: (1) Extremely high consistency: Through real-time height compensation, the problem of uneven glue dot size caused by uneven surface of the glued workpiece is fundamentally eliminated, significantly improving product yield; (2) High efficiency: The simultaneous dispensing of glue from multiple nozzles combined with the flying camera height measurement does not take up extra time for measurement, and the efficiency is several times higher than that of single nozzle dispensing; (3) High flexibility and intelligence: The system can adapt to various uneven dispensing workpieces, reducing the precision requirements of the fixtures and making production change and debugging simpler; (4) High precision and reliability: "Laser displacement sensor ranging + screw valve precision measurement + constant gap control" form a three-in-one precision guarantee, which is especially suitable for high-end fields such as chip packaging and Mini-LED.
[0042] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
