Abstract

The application belongs to the technical field of PCB detection track, and discloses a double-side detection track conveying device, which comprises a track, a material pulling mechanism and a clamping mechanism. The material pulling mechanism is installed on the track. The clamping mechanism comprises a driving part, a rotating shaft and a clamping plate. The driving part is installed along the length direction or the width direction of the track. The rotating shaft is transmissionally connected to the output end of the driving part. The clamping plate is oppositely arranged with the material pulling mechanism and is connected to the rotating shaft. The clamping plate is located at the detection position of the track. The driving part can drive the rotating shaft to rotate with the clamping plate to compress the material, so as to facilitate the up-and-down double-side detection of the material. The driving part is installed along the length direction of the track, which can reduce the track blocking edge. The rotating shaft rotates with the clamping plate to compress the material. The height of the driving end is low, the light source is blocked less, and thus the detection effect of the edge element of the plate is improved.

Description

Technical Field

[0001] This invention relates to the field of PCB board inspection track technology, and in particular to a double-sided inspection track conveying device. Background Technology

[0002] Defects may occur on PCBs after wave soldering, such as insufficient solder, slag inclusion, and short circuits. Therefore, after soldering, the PCBs need to be transported to testing equipment for inspection. The inspection light source is located on the upper and lower sides of the track to achieve double-sided inspection. If the track is too thick (the distance between the imaging equipment and the PCB is too large), the light source on the side of the PCB closest to the track cannot be illuminated, that is, the track will block the light source. This may affect the inspection results of components on the edge of the board.

[0003] Based on the above situation, we urgently need to design a double-sided inspection track conveyor device to solve the above problems. Summary of the Invention

[0004] One object of the present invention is to provide a double-sided inspection track conveyor device that can reduce the track edge, thereby improving the inspection effect of material plate edge components.

[0008] A material pulling mechanism is installed on the track, and the material pulling mechanism is capable of conveying materials along the length of the track;

[0009] The clamping mechanism includes a drive component, a rotating shaft, and a clamping plate. The drive component is installed along the length or width direction of the track. The rotating shaft is driven to the output end of the drive component. The clamping plate is disposed opposite to the material pulling mechanism and connected to the rotating shaft. The clamping plate is located at the detection position of the track. The drive component can drive the rotating shaft to rotate the clamping plate in the forward direction to clamp or release the material.

[0010] As a preferred embodiment, the driving component is configured as a linear driving component, and the clamping mechanism further includes a linkage component. One end of the linkage component is connected to the output end of the linear driving component, and the other end is connected to the rotating shaft. The linkage component can convert the linear driving force of the linear driving component into a rotational driving force.

[0011] As a preferred embodiment, the linkage component includes:

[0012] A rotating component is rotatably mounted on the rotating shaft;

[0013] A push rod is provided with an abutment portion at its end near the rotating member. The height of the abutment portion in the track height direction gradually increases in the direction away from the rotating member. The abutment portion can abut against the rotating member to push the rotating member tangentially along the axis of rotation.

[0014] As a preferred embodiment, the rotating shaft is rotatably mounted on the track, and the linkage assembly further includes a reset component, one end of which is fixed to the rotating shaft and the other end of which is fixed to the track. The reset component can drive the rotating shaft to rotate in the opposite direction.

[0015] As a preferred embodiment, a mounting block extending toward the rotating shaft is installed on the track, the rotating shaft is rotatably connected to the mounting block, and the reset element is a torsion spring, which is sleeved on the rotating shaft and fixed at one end to the rotating shaft and at the other end to the mounting block.

[0016] As a preferred embodiment, the rotating components are installed at both ends of the rotating shaft, and the two linear drive components and the push rod are installed opposite each other on the track and located at both ends of the rotating shaft, with the two linear drive components driving asynchronously.

One end of the C-shaped clamping plate is connected to the rotating shaft, the middle part spans the track, and the other end can press the material on the inner side of the track.

[0018] As a preferred embodiment, the rotating shaft is configured as a prism, and the clamping plate has a polygonal insertion hole that mates with the prism, and the prism is inserted into the insertion hole.

[0019] As a preferred embodiment, the width of the track gradually decreases in the direction away from the material.

[0020] As a preferred embodiment, the material pulling mechanism includes:

[0021] Multiple rollers are rotatably connected to the end of the track away from the detection position;

[0022] The belt passes sequentially around the multiple rollers and is positioned opposite to the clamping plate;

[0023] A rotary drive is installed at the end of the track away from the detection position. The belt drive is connected to the output end of the rotary drive. The rotary drive can drive the belt to rotate so as to move the material along the length of the track.

[0036] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 and Figure 2As shown, this embodiment provides a double-sided detection track conveying device, including a track 1, a material pulling mechanism 2, and a clamping mechanism 3. Two tracks 1 are arranged in parallel. The material pulling mechanism 2 is installed on the track 1. In this embodiment, the material is a PCB board 4. The tray of the PCB board 4 is placed on the material pulling mechanism 2. The material pulling mechanism 2 can convey the material along the length direction of the track 1. The clamping mechanism 3 includes a drive component, a rotating shaft 32, and a clamping plate 33. The drive component can be installed along the length direction or the width direction of the track 1. In this embodiment, the drive component is installed on the side wall of the track 1 along the length direction of the track 1. The rotating shaft 32 is connected to the output end of the drive component. The clamping plate 33 is arranged opposite to the material pulling mechanism 2 and connected to the rotating shaft 32. It can be understood that a detection position 11 for detecting the PCB board 4 is provided on the track 1. Detection light sources are installed on the upper and lower sides of the detection position 11. In this embodiment, the clamping plate 33 is located at the detection position 11 of the track 1. When the material pulling mechanism 2 conveys the PCB board 4 to the detection position 11, the driving component can drive the rotating shaft 32 to rotate the clamping plate 33 in the forward direction, thereby pressing the PCB board 4 onto the material pulling mechanism 2 for easy detection. After the detection is completed, the rotating shaft 32 rotates in the reverse direction to release the PCB board 4, and the material pulling mechanism 2 conveys the PCB board 4 away from the detection position 11. During this process, since the light from the detection light source is diffused, if the edge of the track 1 is too high, it will block the detection light source, thus affecting the testing effect of the components on the edge of the PCB board 4. However, in this embodiment, the driving component is installed along the length of the track 1, which lowers the edge of the track 1. Furthermore, the driving component drives the rotating shaft 32 to rotate the clamping plate 33 to press the material. The clamping plate 33 is directly connected to the rotating shaft 32, which is also set along the length of the track 1. The low height of the rotating drive end further reduces the light blocking of the light source, thereby improving the detection effect of the components on the edge of the board. In other embodiments of the present invention, the clamping plate 33 can also press the PCB board 4 onto the track 1 by pressing against the material pulling mechanism 2.

[0041] In this embodiment, the driving component is a linear driving component 31, which can be a cylinder, thus occupying less space. The clamping mechanism 3 also includes a linkage component 34, one end of which is connected to the output end of the linear driving component 31, and the other end is connected to the rotating shaft 32. When the linear driving component 31 drives the linkage component 34 linearly along the length of the track 1, the linkage component 34 can convert the linear driving force into a rotational driving force and drive the rotating shaft 32 to rotate. In other embodiments of the present invention, the driving component can also be a motor, with the output end of the motor directly connected to the rotating shaft 32, thereby driving the rotating shaft 32 to rotate with the clamping plate 33.

[0042] like Figure 2 and Figure 3As shown, the linkage assembly 34 includes a rotating component 341, a base 342, and a push rod 343. The rotating component 341 can be configured as a roller or a bearing. In this embodiment, the base 342 is fitted onto the rotating shaft 32, allowing the rotating shaft 32 to rotate with the base 342. The bearing is mounted on the base 342 and located between the rotating shaft 32 and the track 1. The push rod 343 has an abutment portion 3431 at its end near the bearing. The height of the abutment portion 3431 gradually increases in the direction away from the bearing, meaning the abutment portion 3431 is configured as an inclined surface facing the bearing. When the linear drive component 31 drives the push rod 343 along the length direction of the track 1, the abutment portion 3431 of the push rod 343 abuts against the bearing. On one hand, the bearing rotates, thereby eliminating the driving force on the rotating shaft 32 along the length direction of the track 1. On the other hand, the bearing moves along the height direction of the track 1, that is, it pushes the bearing tangentially along the rotating shaft 32, thereby causing the rotating shaft 32 to rotate. In other embodiments of the present invention, the linear drive 31 is installed along the width direction of the track 1, and the linkage component 34 is configured as a double link. One end of the double link is hinged to the output end of the linear drive 31, and the other end is fixed to the rotating shaft 32, which can also drive the rotating shaft 32 to rotate.

[0043] In a preferred embodiment, the rotating shaft 32 is rotatably mounted on the track 1. The linkage assembly 34 also includes a reset member, one end of which is fixed to the rotating shaft 32 and the other end to the track 1. The linear drive member 31 can drive the rotating shaft 32 to rotate in the forward direction, and the reset member can drive the rotating shaft 32 to rotate in the reverse direction to reset it. The structure is simple. For example, the clamping plate 33 is initially in a pressed state. The linear drive member 31 can drive the rotating shaft 32 to rotate in the forward direction to loosen the clamping plate 33. When the PCB board 4 moves to the detection position 11, the reset member can drive the rotating shaft 32 to rotate in the reverse direction to make the clamping plate 33 press the PCB board 4. Of course, when the PCB board 4 moves to the detection position 11, the linear drive member 31 can drive the rotating shaft 32 to rotate in the forward direction to make the clamping plate 33 press the PCB board 4. After the detection is completed, the reset member drives the rotating shaft 32 to rotate in the reverse direction to make the clamping plate 33 release the PCB board 4. In other embodiments of the present invention, a driving member, a push rod 343 and a rotating member 341 may be provided at both ends of the rotating shaft 32. The abutting portions 3431 of the two push rods 343 are arranged opposite to each other. One driving member, push rod 343 and rotating member 341 can drive the rotating shaft 32 to rotate in the forward direction, and the other driving member, push rod 343 and rotating member 341 can drive the rotating shaft 32 to rotate in the reverse direction.

[0044] Specifically, an extended mounting block 12 is fixed on the track 1, and the two ends of the rotating shaft 32 are rotatably connected to the two mounting blocks 12 respectively. A collar 345 is fixedly sleeved on the rotating shaft 32. In this embodiment, the reset component is a torsion spring 344, which is sleeved on the rotating shaft 32 and has one end fixed to the collar 345 and the other end fixed to the mounting block 12, resulting in a simple structure. In other embodiments of the present invention, the reset component can also be a rubber band, with one end fixed to the track 1 and the other end fixed to the rotating shaft 32. The rubber band is initially in a taut state, and the linear drive 31 drives the rotating shaft 32 to rotate, causing the rubber band to wrap around the rotating shaft 32. Subsequently, under the action of the elasticity of the rubber band, the rotating shaft 32 can also be driven to reset.

[0045] In this embodiment, rotating members 341 are installed at both ends of the rotating shaft 32. Two linear drive members 31 and push rods 343 are mounted opposite each other on the track 1 and located at both ends of the rotating shaft 32. The abutment portions 3431 of the push rods 343 are arranged facing each other. One linear drive member 31 and push rod 343 can drive the rotating shaft 32 to rotate to press or release the first batch of PCB boards 4, and the other linear drive member 31 and push rod 343 can drive the rotating shaft 32 to rotate to press or release the second batch of PCB boards 4. The two linear drive members 31 and push rods 343 sequentially drive the rotating shaft 32 to rotate, thereby improving work efficiency.

[0046] like Figure 1 As shown, the drive unit is installed on the outer wall of the track 1. The clamp 33 is C-shaped. One end of the C-shaped clamp 33 is connected to the rotating shaft 32 on the outer side of the track 1, the middle part spans the track 1, and the other end is located on the inner side of the track 1. The structure is compact, and the clamp 33 with both ends facing downward can further reduce the edge of the track 1.

[0047] like Figure 3 As shown, specifically, the rotating shaft 32 is configured as a square prism, pentagonal prism, or hexagonal prism. In this embodiment, the rotating shaft 32 is configured as a hexagonal prism. The clamping plate 33 has hexagonal insertion holes 331 that mate with the prism. The prism is inserted into the insertion holes 331 to rotate the clamping plate 33 synchronously, resulting in a simple structure. In other embodiments of the present invention, the clamping plate 33 can also be fixed to the rotating shaft 32 with screws, and the rotating shaft 32 can also rotate the clamping plate 33.

[0048] As a preferred embodiment, the width of track 1 gradually decreases in the direction away from PCB board 4, and the two parallel tracks 1 are provided with outwardly flared slopes. It is understood that such a structural arrangement can further reduce the obstruction of the detection light source, thereby improving the detection effect of the components on the edge of PCB board 4.

[0049] like Figure 4 and Figure 5As shown, the double-sided detection track conveying device also includes a material pulling mechanism 2. The material pulling mechanism 2 includes rollers 21, belts 22, and a rotary drive component 23. The number of rollers 21 can be set according to actual needs. Multiple rollers 21 are rotatably connected to the side wall of the track 1 and form a ring. Multiple rollers 21 are all located at the end of the track 1 away from the detection position 11. The belt 22 passes around all the rollers 21 in sequence and passes through the detection position 11 of the track 1. The belt 22 located at the detection position 11 is arranged opposite to the clamping plate 33. The rotary drive component 23 can be set as a pneumatic motor or an electric motor. In this embodiment, the rotary drive component 23 is an electric motor. The electric motor is installed on the side wall of the track 1 and located at the end of the track 1 away from the detection position 11. Both the rollers 21 and the electric motor are installed at the end away from the detection position 11, which can further reduce the obstruction of the track 1 at the detection position 11 and reduce the obstruction of the detection light source. PCB board 4 is placed on belt 22. The motor drives belt 22 to rotate, and belt 22 can move PCB board 4 to detection position 11. Then, clamping plate 33 presses PCB board 4 onto belt 22 and track 1 to fix PCB board 4. In other embodiments of the present invention, a linear module can also be used to push PCB board 4 along track 1 along the length of track 1.

[0050] In a preferred embodiment, the feeding mechanism 2 further includes an adjusting block 24, wherein a first roller 21 is rotatably mounted on the adjusting block 24, a second roller 21 is provided on one side of the first roller 21, and a belt 22 passes sequentially around the bottom of the second roller 21 and the top of the first roller 21. The adjusting block 24 has a slotted hole 241, allowing it to be positionably mounted on the track 1, thus adjusting the distance between the first roller 21 and the second roller 21. It is understood that when the distance between the first roller 21 and the second roller 21 decreases, the belt 22 loosens; when the distance increases, the belt 22 tightens, thereby achieving adjustable belt tension and meeting diverse user needs.
