Description

Technical Field

[0001] This utility model relates to the field of optical module processing technology, and in particular to a dispensing device for assembling optical modules. Background Technology

[0002] Currently, the dispensing process for optical modules still relies heavily on manual operation in many production scenarios. However, operators struggle to precisely control the amount of adhesive dispensed each time, easily leading to uneven application. Excessive adhesive in some areas may result in overflow and waste, while insufficient adhesive in others fails to meet heat dissipation requirements. Furthermore, variations in the force and angle of manual operation can cause inconsistent adhesion between the thermally conductive gel and the workpiece surface, leading to the gel easily detaching and disrupting the heat dissipation path of the optical module, thus reducing the equipment's heat dissipation efficiency.

[0003] To address the aforementioned technical problems associated with manual dispensing, existing technologies have yielded relevant improvements, such as the "Optical Module Dispensing Device" (application number CN202421397063.0). This existing solution primarily comprises four core components: a frame, a displacement component, a dispensing component, and a fixture. The displacement component is mounted on the frame, and the dispensing component is mounted on it. Movement of the displacement component allows the dispensing component to adjust its position, enabling dispensing of different workpieces. The fixture is used to fix the workpiece in place and is pre-installed in a preset position to facilitate rapid workpiece positioning by the displacement component. From a design perspective, this solution, through the fixture's limiting effect on the workpiece, prevents displacement during transportation or dispensing, ensuring dispensing accuracy. Furthermore, by using the displacement component to drive the dispensing component to dispense dispensing onto multiple workpieces, and by utilizing the pre-installed fixture in a preset position, the step of repositioning the fixture and workpiece by the displacement component is eliminated. Theoretically, this can improve the shortcomings of manual dispensing to a certain extent, enhancing dispensing efficiency and quality.

[0004] However, in practical applications, the existing technical solution still has the following drawbacks: before the dispensing operation starts, the workpieces to be processed need to be manually or mechanically loaded into the fixture one by one, which is a cumbersome operation; secondly, the fixture with the workpieces loaded needs to be transferred to the preset dispensing position by manual handling or robotic arm transfer, which adds extra operation steps and reduces production efficiency. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a dispensing device for assembling optical modules, comprising: Dispensing mechanism; A workpiece conveying mechanism, which is integrally positioned below the dispensing mechanism, includes: The workpiece conveyor adopts a double belt conveyor structure, and guide structures parallel to the double belt conveyor structure are provided on both sides of the load-bearing section of the double belt conveyor structure. The blocking mechanism includes a second power unit and a stop block. The stop block is disposed between two sets of conveyor belts in the double belt conveyor structure, and the second power unit drives the stop block to move up and down.

[0006] This invention achieves continuous workpiece transport through a workpiece conveyor with a dual-belt conveyor structure. The optical module workpiece to be glued can be directly placed on the dual-belt conveyor structure without the need for separate tooling, eliminating the cumbersome workpiece clamping steps of existing technologies. Simultaneously, the dual-belt conveyor structure can directly transport the workpiece to the preset glue-dispensing position below the glue-dispensing mechanism, eliminating the need for additional manual or robotic arm transfer of tooling, thus improving operational continuity and production efficiency. The guide structure can laterally limit the workpiece during transport, reducing lateral deviation. A second power device drives the stop to rise and fall: when the workpiece is transported to the preset position directly below the glue-dispensing mechanism, the stop rises, preventing further movement and fixing the workpiece at the glue-dispensing position. This eliminates the need for frequent position adjustments by the glue-dispensing mechanism. Furthermore, the glue-dispensing mechanism can output thermally conductive gel in the preset area requiring heat dissipation from the optical module, achieving automatic glue dispensing.

[0007] Furthermore, the workpiece conveying mechanism also includes: The lower positioning mechanism includes a third power device and a lower positioning column. The lower positioning column is set to correspond to the positioning hole on the lower surface of the workpiece and matches the positioning hole on the lower surface of the workpiece. The third power device drives the positioning column to move vertically. The upper positioning mechanism includes a first power device and an upper positioning column. The upper positioning column is set corresponding to the positioning hole on the upper surface of the workpiece and matches the positioning hole on the upper surface of the workpiece. The first power device drives the upper positioning column to move vertically.

[0008] The lower positioning column is vertically raised by the third power device and inserted into the positioning hole on the lower surface of the workpiece to achieve bottom positioning. At the same time, the upper positioning column is vertically lowered by the first power device and inserted into the positioning hole on the upper surface of the workpiece to complete top positioning. This restricts the vertical movement of the workpiece and also constrains the horizontal deviation of the workpiece, thus improving the accuracy of dispensing.

[0009] Furthermore, the dispensing mechanism includes: A dispensing device, wherein there are two sets of dispensing devices arranged opposite to each other; The fifth power unit drives the two sets of dispensing devices to rotate in opposite directions.

[0010] Furthermore, the two sets of dispensing devices are connected to the fifth power unit via a gear and rack mechanism.

[0011] Driven by the fifth power unit, the two sets of dispensing units can synchronously adjust their angles in opposite directions to dispense glue to symmetrical areas of the same optical module workpiece, achieving "zonal coverage". One set processes the left side of the workpiece, while the other set processes the right side simultaneously, reducing the time wasted caused by repeated movement of a single dispensing unit and improving dispensing efficiency.

[0012] Furthermore, the dispensing device also includes a lifting mechanism, on which the dispensing mechanism is mounted and drives the dispensing mechanism to move vertically.

[0013] Furthermore, the lifting mechanism includes: Fourth power unit; The third slider is connected to the fourth power unit via a synchronous belt pulley structure.

[0014] The vertical movement of the dispensing mechanism, driven by the lifting mechanism, allows for flexible adjustment of the distance between the dispensing device and the workpiece surface, enhancing the device's compatibility with workpieces requiring dispensing at different heights.

[0015] This utility model has the following advantages: This invention achieves continuous workpiece transport through a workpiece conveyor with a dual-belt conveyor structure. The optical module workpiece to be glued can be directly placed on the dual-belt conveyor structure without the need for separate tooling, eliminating the cumbersome workpiece clamping steps of existing technologies. Simultaneously, the dual-belt conveyor structure can directly transport the workpiece to the preset glue-dispensing position below the glue-dispensing mechanism, eliminating the need for additional manual or robotic arm transfer of tooling, thus improving operational continuity and production efficiency. The guide structure can laterally limit the workpiece during transport, reducing lateral deviation. A second power device drives the stop to rise and fall: when the workpiece is transported to the preset position directly below the glue-dispensing mechanism, the stop rises, preventing further movement and fixing the workpiece at the glue-dispensing position. This eliminates the need for frequent position adjustments by the glue-dispensing mechanism. Furthermore, the glue-dispensing mechanism can output thermally conductive gel in the preset area requiring heat dissipation from the optical module, achieving automatic glue dispensing.

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0020] As described in the background section, before starting the dispensing operation, the workpieces to be processed must be manually or mechanically loaded into the fixture one by one, which is a cumbersome operation. Secondly, the fixture with the workpieces loaded must be transferred to the preset dispensing position by manual handling or robotic arm transfer, which adds extra operation steps and reduces production efficiency.

[0021] Example 1: Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a dispensing device for assembling optical modules, such as... Figure 1 As shown, the dispensing device includes: Dispensing mechanism 400; The workpiece conveying mechanism 100 is integrally positioned below the dispensing mechanism, as shown below. Figure 2 , 3 As shown, the workpiece conveying mechanism includes: The workpiece conveyor 110 adopts a double belt conveyor structure, and guide structures parallel to the double belt conveyor structure are provided on both sides of the load-bearing section of the double belt conveyor structure. Blocking mechanism 130, such as Figure 4 As shown, the blocking mechanism includes a second power unit 131 and a stop block 132. The stop block is disposed between two sets of conveyor belts in the double belt conveyor structure, and the second power unit drives the stop block to move up and down.

[0022] Specifically, in this embodiment, during use, the operator or automated feeding equipment places the optical module workpiece to be glued onto the double-belt conveyor structure of the workpiece conveyor. The double-belt conveyor structure moves the workpiece towards the preset glue-dispensing position below the glue-dispensing mechanism. During this process, because the guide structure is parallel to the double-belt conveying direction and the spacing is adapted to the workpiece width, it can laterally limit the moving workpiece and constrain its lateral displacement. When the workpiece, driven by the double-belt conveyor structure, approaches the preset glue-dispensing position directly below the glue-dispensing mechanism, the device's position detection sensor (such as a photoelectric sensor, preset in front of the glue-dispensing position) triggers a signal and feeds back the information "workpiece is about to arrive" to the control system. After receiving the signal, the control system immediately sends an action command to the second power unit of the blocking mechanism. The second power unit drives the stop block located between the two sets of conveyor belts of the double-belt conveyor structure to rise vertically until the top of the stop block is higher than the bearing surface of the double-belt conveyor structure. At this time, the workpiece that has moved to this position will abut against the stop block, be blocked from continuing to move forward, and stop at the preset glue-dispensing position directly below the glue-dispensing mechanism. After the workpiece is fixed at the preset dispensing position by the stop, the position detection sensor sends a "workpiece positioning complete" signal back to the control system. The control system then simultaneously triggers the dispensing mechanism to start, dispensing thermally conductive gel to the target area of ​​the workpiece. After completing a single dispensing operation, the dispensing mechanism sends a "dispensing complete" signal to the control system. The control system then instructs the second power unit to drive the stop vertically downwards to reset (returning to the space between the two belts of the dual-belt conveyor structure, without obstructing workpiece movement). After the stop resets, the dual-belt conveyor structure continues to move the dispensed workpiece forward, transporting it to the unloading area of ​​the device (or connecting to the next production process, such as the gel curing process). In this embodiment, the second power unit includes, but is not limited to, cylinders, electric cylinders, hydraulic cylinders, or other devices capable of driving linear motion of components. Furthermore, the dispensing device may also include a bracket 200, on which both the workpiece conveying mechanism and the dispensing mechanism are mounted.

[0023] This embodiment achieves continuous workpiece transport through a workpiece conveyor with a dual-belt conveyor structure. The optical module workpiece to be glued can be directly placed on the dual-belt conveyor structure without the need for separate tooling, eliminating the cumbersome workpiece clamping steps in existing technologies. Simultaneously, the dual-belt conveyor structure can directly transport the workpiece to the preset glue dispensing position below the glue dispensing mechanism, eliminating the need for additional manual or robotic arm transfer of tooling, thus improving operational continuity and production efficiency. The guide structure can laterally limit the workpiece during transport, reducing lateral deviation. A second power device drives the stop to rise and fall: when the workpiece is transported to the preset position directly below the glue dispensing mechanism, the stop rises, preventing further movement and fixing the workpiece at the glue dispensing position. This eliminates the need for frequent position adjustments by the glue dispensing mechanism. Furthermore, the glue dispensing mechanism can output thermally conductive gel in the preset area requiring heat dissipation from the optical module, achieving automatic glue dispensing.

[0024] In this embodiment, as Figure 3 As shown, the workpiece conveying mechanism further includes: Lower positioning mechanism 140, such as Figure 6 As shown, the lower positioning mechanism includes a third power device 141 and a lower positioning column 143. The lower positioning column is set corresponding to the positioning hole on the lower surface of the workpiece and matches the positioning hole on the lower surface of the workpiece. The third power device drives the positioning column to move vertically. Upper positioning mechanism 120, such as Figure 5 As shown, the upper positioning mechanism includes a first power device 121 and an upper positioning column 124. The upper positioning column is set corresponding to the positioning hole on the upper surface of the workpiece and matches the positioning hole on the upper surface of the workpiece. The first power device drives the upper positioning column to move vertically.

[0025] Specifically, the first and third power devices include, but are not limited to, cylinders, electric cylinders, hydraulic cylinders, or other devices capable of driving linear motion of components, such as... Figure 5As shown, the upper positioning mechanism may further include a first slider 122, which slides in cooperation with the bracket via a guide mechanism (e.g., a guide rail-slider mechanism, a guide rod-slider mechanism, etc.). An upper positioning plate 123 is fixed on the top of the first slider. The upper positioning plate is horizontally positioned above the workpiece conveyor and is U-shaped. Upper positioning posts are fixed at both ends of the upper positioning plate. Furthermore, the lower positioning mechanism may also include a second slider 142, which also slides in cooperation with the bracket via a guide mechanism (e.g., a guide rail-slider mechanism, a guide rod-slider mechanism, etc.). The second slider is integrally positioned between the two sets of conveyor belts of the workpiece conveyor, and the lower positioning post is fixed on the top of the second slider. When the workpiece approaches a preset position below the dispensing mechanism, the position detection sensor triggers a signal, and the control system controls the second power device of the blocking mechanism to drive the stop block upward, preventing the workpiece from continuing to move and causing the workpiece to stop in the preset positioning area. Subsequently, the control system controls the third power device to drive the second slider to rise vertically, and the lower positioning post fixed on the top of the second slider rises synchronously and inserts into the positioning hole on the lower surface of the workpiece. At the same time, the first power unit drives the first slider to descend vertically, which in turn drives the upper positioning posts fixed at both ends of the U-shaped upper positioning plate to descend synchronously, and the upper positioning posts are inserted into the positioning holes on the upper surface of the workpiece.

[0026] The lower positioning column is vertically raised by the third power device and inserted into the positioning hole on the lower surface of the workpiece to achieve bottom positioning. At the same time, the upper positioning column is vertically lowered by the first power device and inserted into the positioning hole on the upper surface of the workpiece to complete top positioning. This restricts the vertical movement of the workpiece and also constrains the horizontal deviation of the workpiece, thus improving the accuracy of dispensing.

[0027] In this embodiment, as Figure 8 As shown, the dispensing mechanism includes: Dispenser 430, which has two sets of dispensers arranged opposite to each other; The fifth power unit 420 drives the two sets of dispensing devices to rotate in opposite directions.

[0028] The two sets of dispensing devices are connected to the fifth power unit via a gear and rack mechanism 440.

[0029] In this embodiment, the dispensing mechanism may further include a fixed block 410. The fifth power device is fixedly installed on the fixed block. The fifth power device includes, but is not limited to, a cylinder, an electric cylinder, a hydraulic cylinder, or other devices capable of driving linear motion of components. A rack is installed on the output end of the fifth power device. The rack has a double-sided rack structure. The dispensing device is rotatably installed on the fixed block. A gear is installed on the shaft between the dispensing device and the fixed block. The gear meshes with the rack. In addition, the fifth power device in this embodiment may also be a motor, which directly drives one set of dispensing devices to rotate. The two sets of dispensing devices are connected by a gear transmission mechanism.

[0030] Driven by the fifth power unit, the two sets of dispensing devices can synchronously adjust their angles in opposite directions to dispense adhesive to symmetrical areas of the same optical module workpiece, achieving "zonal coverage". One set processes the left side of the workpiece, while the other set processes the right side simultaneously, reducing the time wasted caused by repeated movement of a single dispensing device and improving dispensing efficiency.

[0031] like Figure 1 As shown, the dispensing device also includes a lifting mechanism 300, on which the dispensing mechanism is mounted and drives the dispensing mechanism to move vertically.

[0032] like Figure 7 As shown, the lifting mechanism includes: Fourth power unit 310; The third slider 330 is connected to the fourth power unit via a synchronous belt pulley structure.

[0033] In this embodiment, the fourth power device is an electric motor, which directly drives the synchronous belt pulley structure. The third slider is connected to the belt of the synchronous belt pulley transmission structure. Furthermore, the lifting mechanism may include a mounting part 320, on which the fourth power device can be fixedly mounted. The third slider can slide with the mounting part through a guide structure, and the mounting part is fixed to a bracket. Of course, in addition to the synchronous belt structure, a screw drive structure, a rack and pinion drive structure, or other transmission mechanisms capable of achieving linear displacement of components can also be used. The fourth power device can also be a cylinder, an electric cylinder, a hydraulic cylinder, or other devices capable of achieving linear displacement of components.

[0034] The vertical movement of the dispensing mechanism, driven by the lifting mechanism, allows for flexible adjustment of the distance between the dispensing device and the workpiece surface, enhancing the device's compatibility with workpieces requiring dispensing at different heights.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
