[0029] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] In the related art, the glue dispensing machine realizes the glue dispensing operation of the light strip by means of transmission, wherein the light strip is transmitted on the carrier of the glue dispensing machine through the transport mechanism in the glue dispensing machine, and through the transmission of the light strip, the glue dispensing of the long light strip can be realized based on the small-sized glue dispensing machine, which can effectively reduce the floor space occupied by the light strip. However, since the light strip needs to be transmitted, the connection between the light strip and the carrier is not tight, and the light strip may undergo unexpected deformation during the glue dispensing process, resulting in low glue dispensing accuracy and low product yield.

[0032] Based on this, the present application hopes to provide a solution that can solve the above-mentioned technical problems, the details of which will be described in the subsequent embodiments.

[0033] This application embodiment provides a feeding machine, please refer to Figure 1-4 , the loader includes a carrier plate 11, a pressing plate 12, an assembly clamp 13 and an X-axis driving unit 14;

[0034] The carrier plate 11 is mounted on the frame 20 of the dispensing machine, and the carrier plate 11 reciprocates along the X-axis direction under the control of the X-axis driving unit 14;

[0035] The pressing plate 12 is fixed on the carrier plate 11 and forms an adjustable movable connection with the carrier plate 11; the assembly clamp 13 is fixedly arranged on the frame; when the pressing plate 12 clamps and fixes the light strip on the carrier plate 11, the assembly clamp 13 releases the clamping of the light strip, and the carrier plate 11 drives the light strip to perform mobile dispensing operation; when the pressing plate releases the clamping of the light strip on the carrier plate, the assembly clamp clamps and fixes the light strip, and the carrier plate and the pressing plate retreat to the area of ​​the light strip to be glued;

[0036] The feeder in the embodiment of the present application is used to carry and transport the light strip located on the feeder so that the glue dispenser can cover the encapsulation colloid on the light chip of the light strip to form the required COB light strip. Among them, the specific types of COB light strips include but are not limited to linear light strips, point-break light strips, CSP light strips, etc. Specifically, the linear light strip refers to the fluorescent glue covering each light-emitting chip on the light strip connected as a whole. Under the premise of sufficient output power, the linear light strip will emit light as a continuous line. The point-break light strip refers to the fluorescent glue on the light strip is discretely distributed, each light-emitting chip can correspond to an independent fluorescent glue, or multiple adjacent chips are coated with the same fluorescent glue. The shape presented by this light strip is a light string formed by multiple point light sources. The CSP light strip refers to the light-emitting chip of the light strip is a CSP chip pre-encapsulated by fluorescent glue. The characteristic of the CSP chip is that it does not have a bracket and has been mixed with fluorescent glue. Therefore, the glue dispensed by the glue dispenser can be a packaging glue including transparent glue, but not limited to fluorescent glue.

[0037] The feeder carries the light strip, which means that when the light strip is placed on the feeder, the light-emitting surface of the light strip is exposed, and the back of the light-emitting surface faces the carrying mechanism of the feeder. In the embodiment of the present application, the carrying mechanism of the feeder is the carrier 11. When the light-emitting surface is exposed, the glue dispensing head on the glue dispensing machine can apply the encapsulation colloid to the corresponding position during the process of the feeder carrying and transmitting the light strip, thereby realizing the glue dispensing operation.

[0038] In order to ensure the stability of the carrier 11 in conveying the light strip, the carrier 11 is controlled by the X-axis drive unit 14, and the carrier 11 under the control of the X-axis drive unit 14 moves along its length direction, including moving forward along the length direction, and moving backward along the length direction. In other words, the X-axis in the embodiment of the present application refers to the direction axis corresponding to the length direction of the carrier 11. The control operation of the X-axis drive unit 14 is performed based on the control signal issued by the control unit set on the dispensing machine.

[0039] During the process of the carrier 11 conveying the light strip, the relative position relationship between the light strip and the carrier 11 is locked to each other, that is, the light strip maintains a synchronous motion relationship with the carrier 11. In this process, in order to improve the accuracy of the light strip dispensing process, it is necessary to ensure that the position relationship between the light strip and the carrier 11 is very stable. In the embodiment of the present application, in order to improve this stability, a pressure plate 12 is provided, and the light strip is clamped and fixed by the cooperation between the pressure plate 12 and the carrier 11, thereby directly locking the relative position between the light strip and the carrier 11 and the pressure plate 12. Before the clamping and fixing of the light strip by the pressure plate 12 and the carrier 11 is released, the light strip will not have any relative displacement with the carrier 11, so that the light strip can be guaranteed to the maximum extent during the dispensing process of the dispensing machine, and the light strip will not move unexpectedly, thereby performing the dispensing operation on the corresponding area of ​​the light strip. Therefore, at this time, a set of clamps are formed between the pressure plate 12 and the carrier 11, and the clamps are used to achieve a fixed connection to the light strip. Among them, in the dispensing operation on the corresponding area of ​​the light strip, the corresponding area refers to the area where the working area of ​​the carrier 11 corresponds to the light strip when the light strip and the carrier 11 are relatively locked, and the working area of ​​the carrier 11 refers to the area corresponding to the dispensing range of the glue dispenser.

[0040] In some optional embodiments, in order to ensure the stability of dispensing, a corresponding platform needs to be set in the working area of ​​the carrier board 11 to ensure that the light strip can be leveled, while there is no restriction outside the working area of ​​the carrier board 11; for details, please refer to Figure 2 The component structure of the carrier 11 may include a workbench 111 and a guide bar 112. The workbench 111 is located in the working area of ​​the carrier 11. The guide bars 112 are arranged in pairs on the loading side and / or the unloading side of the carrier 11. The workbench 111 is flush with the bearing surface of the guide bar 112. The workbench 111 corresponds to the area where the glue dispenser can dispense glue, that is, the working area. The size of the area is relatively fixed in each glue dispensing process, and different sizes of working areas can be used for different glue dispensing processes. During the glue dispensing process, the motion range of the glue dispensing head on the glue dispensing machine is relatively small. Usually, the main movement of the glue dispensing head is to reciprocate up and down along the Z axis, while only fine-tuning is done on the X and Y axes. Usually, the position compensation of the light strip glue dispensing is performed based on the image of the light strip captured by the camera. Therefore, during the dispensing process, the dispensing of the light strip is mainly achieved by the movement of the working area, that is, the working area will move with the movement of the carrier board 11, with the entrance of the working area opposite to the dispensing head, and gradually move to the exit of the working area opposite to the dispensing head, wherein the entrance of the working area is close to the feed port of the carrier board 11, and the exit of the working area is close to the discharge port of the carrier board 11.

[0041] In some optional embodiments, in order to improve the flatness of the light strip during the dispensing process, thereby improving the processing accuracy, please continue to refer to Figure 2The workbench 111 may also be provided with a vacuum suction plate 1111, and the vacuum suction plate 1111 can level the light strip fixed in the work area by vacuuming.

[0042] In addition to the workbench 111 needing to provide a flat surface for the light strip to be leveled for easy glue dispensing, the rest of the carrier 11 may not be provided with a whole flat surface, but instead, the guide strips 112 arranged in pairs can be used to simply carry the light strip and guide the direction of movement of the light strip. For the carrier 11, the longer its overall length is, the less likely the light strip will deviate to the side. Therefore, by setting the guide strips 112 at at least one end of the two ends of the workbench 111 in the length direction, the length of the carrier 11 can be increased without increasing the area of ​​the workbench 111, thereby improving the stability of the light strip transmission and saving product space.

[0043] In some optional embodiments, please continue to refer to Figure 2 In order to adapt the carrier 11, especially to match the combined structure of the workbench 111 and the guide bar 112 of the carrier 11, the pressing plate 12 may specifically include a main plate 121 and a sub-plate 122, and the main plate 121 and the sub-plate 122 are matched with the workbench 111 and the guide bar 112 respectively. In other words, in the pressing plate 12, the main plate 121 is arranged on the workbench 111, and cooperates with the workbench 111 to clamp and release the light strip; the sub-plate 122 is arranged on the guide bar 112, and cooperates with the guide bar 112 to clamp and release the light strip, and the states of the main plate 121 and the sub-plate 122 are synchronized. For the dispensing operation, generally, it is only necessary to ensure the clamping and releasing operation between the main plate 121 and the workbench 111 to achieve reliable dispensing, and the provision of the sub-plate 122 can further improve the flatness and connection stability of the light strip.

[0044] In some optional embodiments, please continue to refer to Figure 2 The purpose of setting the pressing plate 12 is to cooperate with the carrier plate 11 to clamp and release the light strip. In order to avoid interference with the light strip during the clamping process of the pressing plate 12, the structure of the pressing plate 12 may specifically include sub-plates 123 symmetrically arranged on both sides of the width direction of the carrier plate 11, and the length of the sub-plates 123 matches the length of the working area of ​​the carrier plate 11. By arranging the sub-plates 123 in pairs, the area in the middle of the sub-plates 123 can be vacated, so that the glue dispenser can directly perform the glue dispensing operation on the light strip located below the sub-plates 123 based on the gap between the sub-plates 123 during the glue dispensing process, avoiding the sub-plates 123 from blocking the light strip. The length of the sub-plate 123 matches the length of the working area, which can ensure that when the sub-plate 123 cooperates with the carrier plate 11 to clamp the light strip, the light strip in the entire working area is stable and flat, thereby improving the accuracy of the glue dispensing of the light strip.

[0045] In some alternative embodiments, please refer to Figure 3In order to reduce the difficulty of smooth matching between the sub-board 123 and the carrier board 11, the sub-board 123 includes an extension portion 1231 extending laterally to the middle of the carrier board 11, and a bending portion 1232 arranged at the end of the extension portion 1231, and the bottom of the bending portion 1232 is a smooth plane or a curved surface. The sub-board 123 is set as a structure in which the horizontal extension portion 1231 and the longitudinal bending portion 1232 match each other, which can reduce the difficulty of processing the sub-board 123 itself. It only needs the bottom of the bending portion 1232 to be a smooth plane or a curved surface to achieve smooth clamping of the light strip, which is equivalent to the contact between the sub-board 123 and the light strip being close to the contact between the line and the surface, avoiding the high processing difficulty required for the surface-to-surface contact, and can effectively reduce the manufacturing cost of the equipment. In addition, the material of the sub-board 123 can also be set to have a certain elasticity, and the elasticity can be matched with the hard carrier board 11 to achieve a clamping operation with higher freedom and stability.

[0046] In some optional embodiments, in order to avoid interference of the pressing plate 12 with the light strip, the pressing plate 12 can also be arranged to be located above the working area of ​​the carrier plate 11 as a whole, and a plurality of through holes corresponding to the glue dispensing areas of the light strip are arranged on the pressing plate 12. The through holes arranged on the pressing plate 12 can provide space for glue dispensing of the light strip, and the glue dispensing head can apply the packaging glue on the light strip through the through holes.

[0047] Although the pressure plate 12 and the carrier plate 11 can be used to fix the light strip, the size of the glue dispenser and the feeder is limited. Under the limited size, if the pressure plate 12 and the carrier plate 11 are always clamped and fixed to the light strip, the length of the light strip will inevitably be limited. Therefore, in the embodiment of the present application, the clamping operation of the pressure plate 12 and the carrier plate 11 on the light strip can be released. When released, the relative position between the light strip and the carrier plate 11 is not locked, and relative displacement can occur between the two. Please refer to Figure 4 In this case, in the embodiment of the present application, an assembly clamp 13 fixed on the frame 20 is provided, and the assembly clamp 13 clamps the light strip, so that the light strip is fixedly connected to the assembly clamp 13, that is, fixedly connected to the frame 20; and the carrier plate 11 can move along the X-axis direction, so that the relative position between the light strip and the carrier plate 11 changes, and different areas on the light strip can be switched for glue dispensing operations, that is, different areas of the light strip are correspondingly locked with the working area of ​​the carrier plate 11.

[0048] The assembly clamp 13 can be set on the loading side of the carrier 11, or on the unloading side of the carrier 11, or on both the loading side and the unloading side, that is, the assembly clamp 13 can be set on the loading side and / or the unloading side of the carrier 11.

[0049] In some optional embodiments, in order to achieve glue dispensing of long light strips, during the glue dispensing operation, the assembly clamp 13 releases the light strip, the pressure plate 12 and the carrier plate 11 cooperate to clamp and fix the light strip, and the carrier plate 11 drives the light strip to move toward the discharge side until the carrier plate 11 reaches the first preset position, at which time the glue dispensing head performs the glue dispensing operation on the light strip; in the gap between glue dispensing operations, the pressure plate 12 and the carrier plate 11 release the light strip, and the assembly clamp 13 clamps the light strip, and the carrier plate 11 and the pressure plate 12 retreat synchronously to the area of ​​the light strip to be glued, that is, the area of ​​the light strip to be glued in the next stage. Among them, during the dispensing operation, the positions of the pressing plate 12, the carrier plate 11 and the light strip are fixed to each other, and the carrier plate 11 drives the light strip to move toward the discharge side along the length direction of the carrier plate 11. At this time, the dispensing head performs the dispensing operation based on the movement of the carrier plate 11. The dispensing operation can be continuous dispensing to form a linear light strip. In this case, the dispensing head generally will not be adjusted in the Z-axis direction, and the Y-axis direction will be fine-tuned based on the image taken by the camera, and the carrier plate 11 moves toward the discharge side at a uniform speed until this part of the dispensing operation is completed; or it can be intermittent dispensing, in which case the dispensing head will periodically reciprocate in the Z-axis direction, that is, it will move up and down, and dispense glue when it is closest to the light strip, and stop dispensing glue when it is away from the light strip, and the carrier plate 11 will make a matching stepping motion with the dispensing head, that is, when the dispensing head is closest to the light strip, the carrier plate 11 stops moving, and the carrier plate 11 moves toward the discharge side during the process of the dispensing head moving away from the light strip upward and approaching the light strip downward again. When the working area of ​​the carrier 11 reaches the end, the carrier 11 and the light strip need to be untied from each other, so that the carrier 11 can move back relative to the light strip, while the light strip remains stationary under the clamping of the assembly clamp 13. In this way, the light strip moves "forward" relative to the carrier 11, and the part of the light strip that has been glued will move forward out of the working area, and the area to be glued on the light strip will gradually move forward into the working area. When the area to be glued on the light strip is in place, the pressure plate 12 and the carrier 11 can clamp the light strip again, and the assembly clamp 13 releases the light strip again. The light strip continues to move forward synchronously with the carrier 11 and performs glue dispensing under the drive of the carrier 11, thereby realizing the glue dispensing operation of the long light strip.

[0050] In some optional embodiments, in order to prevent the light strip from being lateral dislocation, tilt, etc., the light strip may further include limit blocks 15, which are arranged on both sides of the length direction of the carrier plate 11. The limit blocks 15 can limit the light strip between the limit blocks 15, and the limit blocks 15 can simply limit the light strip in advance, and then clamp the light strip by means including the pressure plate 12. In order to adapt to light strips of different widths and different numbers, the gap between the limit blocks 15 can be adjusted.

[0051] The present application provides a material loader and a glue dispensing machine, wherein the material loader comprises a carrier plate 11, a pressing plate 12, an assembly clamp 13 and an X-axis driving unit 14; the carrier plate 11 is mounted on a frame 20 of the glue dispensing machine, and the carrier plate 11 reciprocates along the X-axis direction under the control of the X-axis driving unit 14;

[0052] The pressing plate 12 is fixed on the carrier plate 11 and forms an adjustable movable connection with the carrier plate 11; the assembly clamp 13 is fixedly arranged on the frame; when the pressing plate 12 clamps and fixes the light strip on the carrier plate 11, the assembly clamp 13 releases the clamping of the light strip, and the carrier plate 11 drives the light strip to move and dispense glue; when the pressing plate 12 releases the clamping of the light strip on the carrier plate 11, the assembly clamp 13 clamps and fixes the light strip, and the carrier plate 11 and the pressing plate 12 retreat to the area of ​​the light strip to be dispensed glue, so that by arranging the pressing plate 12 on the feeding machine, the pressing plate 12 can clamp and fix the light strip during the dispensing process, thereby improving the stability of the light strip during the dispensing process, thereby improving the dispensing accuracy and improving the product yield; and by releasing the clamping of the light strip by the pressing plate 12, the light strip can be temporarily fixed, thereby moving the carrier plate 11, so that the light strip can be transmitted along the carrier plate 11, meeting the dispensing requirements of light strips of any length.

[0053] The present application also provides a dispensing machine, please refer to Figure 5 , which includes a frame 20, a dispensing mechanism 30, a camera, a control unit and a feeder 10 in the embodiment of the present application; wherein:

[0054] The feeder 10 is mounted on a frame 20;

[0055] The glue dispensing mechanism 30 includes a glue dispensing head and a driving mechanism. The glue dispensing head is mounted on the frame 20 through the driving mechanism, and the glue dispensing head is controlled to move by the driving mechanism.

[0056] The camera is disposed above the carrier plate 11 of the feeder 10 and is used to capture the image of the light strip located on the carrier plate 11;

[0057] The control unit is used to control the feeder 10 and the glue dispensing mechanism 30 according to the image, so as to dispense glue to the light strip.

[0058] The glue dispensing machine in the embodiment of the present application functions to perform glue dispensing operations for the light strip. During the glue dispensing process, the light strip is driven to move by the loader 10, and the glue dispensing head performs glue dispensing operations in the corresponding area of ​​the light strip, thereby forming the required COB light strip.

[0059] The composition structure of the glue dispensing machine includes a frame 20 as a main body and support, a loader 10 for carrying and transporting the light strip, a glue dispensing mechanism 30 for glue dispensing, a camera for calibrating glue dispensing, and a control unit for controlling each component.

[0060] The loader 10 is installed on the frame 20. In the composition structure of the loader 10, its carrier 11 can move in the X-axis direction relative to the frame 20, which is realized by the X-axis driving unit 14. The X-axis driving unit 14 controls the movement of the carrier 11 based on the execution of the control signal sent by the control unit.

[0061] The dispensing mechanism 30 includes a dispensing head for dispensing glue, and a driving mechanism for controlling the movement of the dispensing head, and the dispensing head is installed on the frame 20 through the driving mechanism. The driving mechanism is also based on the control signal sent by the control unit to further control the corresponding movement of the dispensing head, including the up and down movement of the dispensing head in the Z-axis direction, and the fine-tuning movement of the dispensing head in the plane direction. Generally speaking, the up and down movement of the dispensing head in the Z-axis direction is directly related to whether the glue is dispensed or not, and the fine-tuning movement in the plane direction is suitable for compensating the dispensing position according to the light strip image captured by the camera, thereby ensuring the accuracy of the dispensing.

[0062] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
