Description

Technical Field

[0001] This utility model relates to the field of optical module processing technology, and in particular to an optical module packaging workbench. Background Technology

[0002] Currently, most packaging workstations employ an assembly line operation mode for PCB transport and placement. Specifically, this type of equipment continuously transports the PCB to be placed to a preset processing position via a conveyor line. Once the PCB arrives at the processing position, a lifting cylinder located below the conveyor line is activated, pushing a release plate connected to the cylinder's output end upwards along the inner side of the conveyor line, thus lifting the PCB off the conveyor line and freeing it from the support and transmission of the transport mechanism. In this state, the placement unit located above the processing position begins the component placement operation, placing the components onto the designated placement area on the PCB surface.

[0003] However, the aforementioned existing technical solutions have the following drawbacks in practical applications: After the PCB is lifted off the conveyor line by the detachment lifting plate, the PCB relies solely on the detachment lifting plate for bottom support, lacking an effective lateral limiting or positioning reinforcement structure. During the placement unit's placement action, the instantaneous contact between the components and the PCB surface generates a certain impact force. Simultaneously, vibrations and airflow disturbances that may occur during equipment operation can easily cause the PCB to shift or wobble horizontally at the processing position. This shift directly results in a mismatch between the placement unit's positioning reference and the PCB's actual position, leading to component placement deviations. This not only reduces product placement accuracy and yield but may also increase production costs due to rework, affecting the stability and efficiency of the packaging operation. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an optical module packaging workbench, comprising: Installation platform; An automatic feeding conveyor line is fixedly installed on the mounting platform. The placement unit is positioned above the automatic board feeding conveyor line. The automatic board feeding conveyor line includes: First transport; The second conveyor is arranged relative to the first conveyor and is parallel to the first conveyor. The first conveyor and the second conveyor together form a conveying mechanism that drives the PCB to move. A lifting mechanism is disposed between the first conveyor and the second conveyor; The pressure block is provided in two sets, which are respectively fixedly installed on the top of the first conveyor and the second conveyor, and partially extend above the belt of the first conveyor or the second conveyor.

[0005] This invention uses a lifting mechanism to lift the PCB. As the PCB rises, its upper edge gradually contacts the lower surface of the pressure block until they come into contact. This allows the pressure block to exert an auxiliary downward pressure on both sides of the PCB, reducing horizontal shift or wobbling of the PCB at the processing position. The structure is simple and improves the problem of mounting position deviation caused by PCB offset in the prior art.

[0006] Furthermore, a second oblong hole is provided on the surface of the pressure block, and a bolt is threadedly connected to the first or second conveyor through the second oblong hole from top to bottom to fix the pressure block.

[0007] This invention allows for horizontal displacement adjustment of the pressure block by loosening the bolts, enabling it to be adapted to the mounting width requirements of the PCB and improving the versatility and applicability of the packaging workbench.

[0008] Furthermore, the lifting mechanism includes: First power unit; The lifting plate is connected to the first power device, which drives the lifting plate to move vertically.

[0009] The first power unit drives the lifting plate to move vertically, so that the PCB is lifted to the preset processing height.

[0010] Furthermore, the lifting plate has a first waist-shaped hole extending in the vertical direction, and a slider is provided on the inner side of the first conveyor and the second conveyor corresponding to the position of the first waist-shaped hole, the slider being slidably engaged in the first waist-shaped hole.

[0011] When the first power unit drives the lifting plate to rise and fall, the slider slides along the inner wall of the first oblong hole, which can limit the movement trajectory of the lifting plate, reduce its horizontal deviation or swaying during vertical linear movement, and improve the movement accuracy of the lifting plate. Furthermore, the automatic feeding conveyor line also includes a clamping mechanism, which is mounted on the second conveyor corresponding to the lifting mechanism. The clamping mechanism includes: Second power unit; The clamping block slides on the top of the second conveyor and is driven by the second power device to move horizontally linearly along the conveying direction perpendicular to the second conveyor. The clamping block acts on one side of the PCB to make it press against the inner side of the first conveyor.

[0012] The second power unit drives the clamping block to move horizontally along the direction perpendicular to the conveying direction, which can push the PCB to the inside of the first conveyor to press it tightly, thereby reducing the lateral gap of the PCB on the conveying mechanism. In the process of mounting, in conjunction with the downward pressure of the pressure block, the PCB is fixed at the component mounting station, further improving the stability of the mounting process.

[0013] Furthermore, the lower surface of the portion of the pressure block located above the first or second conveyor belt and the contact surface between the clamping block and the PCB are covered with a flexible layer.

[0014] The flexible layer on the lower surface of the clamping block and the contact surface of the clamping block forms a buffer protection structure, preventing PCB edge impacts, surface scratches, or circuit damage caused by rigid contact or friction during the clamping block's positioning and clamping process. Furthermore, the flexible layer surface has a higher coefficient of friction than rigid materials, generating greater static friction when in contact with the PCB. Combined with the clamping force and positioning effect of the clamping block, this further restricts the PCB's tendency to slide during processing, reducing the risk of displacement due to mounting impact and equipment vibration.

[0015] Furthermore, the second conveyor slides into the mounting platform, and a lead screw is rotatably mounted on the mounting platform. The lead screw is threadedly connected to the second conveyor, and a handwheel is mounted at one end of the lead screw.

[0016] By rotating the handwheel to drive the lead screw, the second conveyor connected to the lead screw can slide along the mounting table, thereby adjusting the distance between the first and second conveyors. This allows it to adapt to PCB processing needs with a wider range of widths, expanding the applicable scenarios of the packaging workbench.

[0017] This utility model has the following advantages: This invention uses a lifting mechanism to lift the PCB. As the PCB rises, its upper edge gradually contacts the lower surface of the pressure block until they come into contact. This allows the pressure block to exert an auxiliary downward pressure on both sides of the PCB, reducing horizontal shift or wobbling of the PCB at the processing position. The structure is simple and improves the problem of mounting position deviation caused by PCB offset in the prior art. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] 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.

[0021] As described in the background section, when the placement unit performs the placement action, the instantaneous contact between the component and the PCB surface generates a certain impact force. Simultaneously, external forces such as vibrations and airflow disturbances that may occur during equipment operation can easily cause the PCB to shift or wobble horizontally at the processing position. This shift directly causes a mismatch between the positioning reference of the placement unit and the actual position of the PCB, leading to deviations in component placement. This not only reduces the placement accuracy and yield rate of the product but may also increase production costs due to rework, affecting the stability and efficiency of the packaging operation.

[0022] Example 1: Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides an optical module packaging workbench, such as... Figure 1 As shown, the workbench includes: 300 mounting platform; Automatic feeding conveyor line 200, which is fixedly installed on the mounting platform; The mounting unit 100 is positioned above the automatic board feeding conveyor line. like Figures 2-5 As shown, the automatic board feeding conveyor line includes: First conveyor 210; The second conveyor 220 is arranged relative to the first conveyor and is parallel to the first conveyor. The first conveyor and the second conveyor together form a conveying mechanism that drives the PCB to move. Lifting mechanism 240, which is disposed between the first conveyor and the second conveyor; Pressure block 280, which corresponds to the lifting mechanism, is provided in two sets. The two sets of pressure blocks are respectively fixedly installed on the top of the first conveyor and the second conveyor, and partially extend above the belt of the first conveyor or the second conveyor.

[0023] Specifically, in this embodiment, the first and second conveyor belts operate synchronously, forming a continuous conveying channel. The PCB to be mounted enters through the conveyor line inlet and, driven by the two conveyor mechanisms, travels along a preset path towards the processing position corresponding to the lifting mechanism. When the PCB reaches the processing position, the lifting mechanism lifts the PCB, causing it to gradually detach from the conveyor belt, and the upper surfaces of its two side edges gradually contact and abut against the lower surfaces of the corresponding pressure blocks. The pressure blocks exert an auxiliary downward pressure on the two side edges of the PCB, and combined with the bottom support of the lifting plate, constructs a "bottom support and top pressure" positioning structure, limiting the horizontal offset and sway of the PCB. After the PCB is positioned at the processing position, the mounting unit located above the automatic board feeding conveyor line starts and performs component mounting operations according to a preset program. After the component mounting operation of a single PCB is completed, the first power unit of the lifting mechanism drives the lifting plate to descend vertically, causing the PCB to return to the first and second conveyor belts. Driven by the conveyor mechanism, the board moves along the conveyor line toward the exit direction, completing the entire packaging process. Subsequent PCBs then repeat the above steps of board feeding, positioning, and mounting.

[0024] In this embodiment, the PCB is lifted by a lifting mechanism. As the PCB rises, its upper edge gradually contacts the lower surface of the pressure block until they come into contact. This allows the pressure block to exert an auxiliary downward pressure on both sides of the PCB, reducing horizontal offset or wobbling of the PCB at the processing position. The structure is simple and improves the problem of mounting position deviation caused by PCB offset in the prior art.

[0025] For example, such as Figure 5As shown, a second oblong hole 251 is provided on the surface of the pressure block. A bolt passes through the second oblong hole from top to bottom and is threadedly connected to the first or second conveyor to fix the pressure block.

[0026] By loosening the bolts, the position of the pressure block can be adjusted along the length of the oblong hole, thereby achieving horizontal displacement adjustment. This allows for adaptation to the PCB mounting width requirements, improving the versatility and applicability of the packaging workbench.

[0027] For example, such as Figure 5 As shown, the lifting mechanism includes: First power unit 241; The lifting plate 242 is connected to the first power device, which drives the lifting plate to move vertically.

[0028] Specifically, in this embodiment, the first power device can be selected as a cylinder, electric cylinder, hydraulic cylinder or other device that can drive the lifting plate to move linearly. In this embodiment, the first power device drives the lifting plate to move vertically so that the PCB is lifted to a preset processing height.

[0029] For example, such as Figure 5 As shown, the lifting plate has a first waist-shaped hole 243 extending in the vertical direction. A slider is provided on the inner side of the first conveyor and the second conveyor, corresponding to the position of the first waist-shaped hole. The slider is slidably engaged in the first waist-shaped hole.

[0030] When the first power unit drives the lifting plate to rise and fall, the slider slides along the inner wall of the first waist-shaped hole, which can limit the movement trajectory of the lifting plate, reduce its horizontal deviation or swaying in vertical linear movement, and improve the movement accuracy of the lifting plate.

[0031] In addition, such as Figure 3 , 5 As shown, the automatic feeding conveyor line also includes a clamping mechanism 270, which is mounted on the second conveyor corresponding to the lifting mechanism. The clamping mechanism includes: Second power unit 271; Clamping block 273 is slidably fitted on the top of the second conveyor. The clamping block is driven by the second power device to move horizontally linearly along the conveying direction perpendicular to the second conveyor. The clamping block acts on one side of the PCB to make it press against the inner side of the first conveyor.

[0032] In this embodiment, the second power device can be selected as a cylinder, electric cylinder, hydraulic cylinder or other device that can drive the clamping block to move linearly. In addition, multiple clamping blocks and second power devices can be provided, and multiple clamping blocks and second power devices can be fixedly installed on the second conveyor through the connecting part 272.

[0033] The second power unit drives the clamping block to move horizontally along the direction perpendicular to the conveying direction, which can push the PCB to the inside of the first conveyor to press it tightly, thereby reducing the lateral gap of the PCB on the conveying mechanism. During the placement operation, in conjunction with the downward pressing action of the pressure block, the PCB is fixed at the component placement station, further improving the stability of the placement process.

[0034] In this embodiment, the lower surface of the portion of the pressure block located above the first or second conveyor belt and the contact surface between the clamping block and the PCB are covered with a flexible layer.

[0035] The flexible layer on the lower surface of the clamping block and the contact surface of the clamping block forms a buffer protection structure, preventing PCB edge impacts, surface scratches, or circuit damage caused by rigid contact or friction during the clamping block's positioning and clamping process. Furthermore, the flexible layer surface has a higher coefficient of friction than rigid materials, generating greater static friction when in contact with the PCB. Combined with the clamping force and positioning effect of the clamping block, this further restricts the PCB's tendency to slide during processing, reducing the risk of displacement due to mounting impact and equipment vibration.

[0036] In this embodiment, as Figure 2 , 4 As shown, the second conveyor slides into the mounting platform, and a lead screw 260 is rotatably mounted on the mounting platform. The lead screw is threadedly connected to the second conveyor, and a handwheel 230 is mounted at one end of the lead screw.

[0037] By rotating the handwheel to drive the lead screw, the second conveyor connected to the lead screw can slide along the mounting table, thereby adjusting the distance between the first and second conveyors. This allows it to adapt to PCB processing needs with a wider range of widths, expanding the applicable scenarios of the packaging workbench.

[0038] 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. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
