Abstract
Description
Technical Field
[0001] This application relates to the technical field of circuit board manufacturing, and in particular to a sensor bracket structure. Background Technology
[0002] In the process of circuit board manufacturing, it is often necessary to pick up and transfer circuit boards between various manufacturing equipment on automated production lines. This is usually done using robotic arms, which are equipped with suction cups and sensors. When the sensors detect a circuit board on the conveyor belt, the suction cups are used to pick it up.
[0003] Sensors are typically mounted on the robotic arm via a support frame, see reference. Figure 1 , Figure 2 The support body is typically an L-shaped sensor support. It includes a first plate for fixing to the upper surface of the robotic arm's central support rod and a second plate perpendicular to the first plate for fixing to the sensor. The distance between the suction nozzle at the outermost edge and the sensor is the smallest circuit board size that can be detected. The placement of circuit boards of different sizes is based on... Figure 1 The upper right or upper left corner is used as the base point.
[0004] Because the sensor's position is relatively fixed, once the outermost edge of the circuit board moves out of the sensor's sensing range, the sensor will fail to detect the circuit board and thus cannot complete the board grasping action. Furthermore, since various types of circuit boards vary in size, the sensor's position limits the range of circuit boards that can be manufactured, thus requiring further improvement. Utility Model Content
[0005] To improve the compatibility between sensors and circuit boards of different sizes, this application provides a sensor support structure.
[0006] This application provides a sensor bracket structure, which adopts the following technical solution:
[0007] A sensor support structure includes a support body, the support body including a first plate for connecting to the upper surface of a middle support rod of a robotic arm and a second plate disposed perpendicular to the first plate for connecting to a sensor, the sensor being disposed on the side of the second plate away from the first plate; the first plate is provided with an extension portion in the direction away from the sensor, the extension portion is provided with mounting points detachably connected to the upper surface of the support rod, and a plurality of mounting points are spaced apart along the length direction of the extension portion.
[0008] By adopting the above technical solution, and by providing an extension section with several mounting points that are detachably connected to the upper surface of the support rod, the position of the sensor can be adjusted according to the size of the circuit board to be produced, thereby improving the compatibility between the sensor and circuit boards of different sizes.
[0009] Preferably, it also includes several fixing members, the first plate is detachably connected to the support rod through the fixing members, the sensor is also detachably connected to the second plate through the fixing members, and the extension is also detachably connected to the support rod through the fixing members.
[0010] By adopting the above technical solution, the bracket body and extension are detachably connected to the support rod by a fastener, and it is also used to detachably connect the sensor to the second plate.
[0011] Preferably, the fixing member is a fixing bolt and a fixing nut threaded to the fixing bolt. The first plate has a first through hole through its own thickness for the fixing bolt to pass through. The fixing bolt on the first plate is threaded to the support rod. The second plate has a second through hole through its own thickness for the fixing bolt to pass through.
[0012] Preferably, the extension portion is an extension plate integrally formed with the second plate body, the mounting point is a third through hole opened through the upper surface of the extension plate, a plurality of third through holes are interconnected and connected with the first through hole to form a strip hole, the upper surface of the support rod is provided with a first tooth groove, the lower surface of the first plate body near the support rod is provided with a second tooth groove that engages with the first tooth groove, and the extension plate is also provided with a second tooth groove that engages with the first tooth groove.
[0013] By adopting the above technical solution, several third perforations are interconnected and connected with the first perforation to form a strip hole, which increases the adjustable range. Although the extension plate is tightened by fixing bolts, the first plate or the extension plate moves along the width of the support rod. The movement is restricted by the meshing between the first and second tooth grooves, which increases the fixing effect of the sensor.
[0014] Preferably, the extension includes a plurality of extension plates that are rotatably connected in sequence, with the extension plate closest to the first plate being rotatably connected to the first plate, and the extension plate being rotatably foldable to the first plate or the other extension plates.
[0015] By adopting the above technical solution, although the length of the first plate is extended by the extension part, it can be seen from the figure that if the extension part is too long, it may affect the robotic arm's gripping of the circuit board on the other side of the support rod. In this regard, the extension part includes several rotatably connected extension plates for folding and fixing, and it is also convenient to add the corresponding number of extension plates as needed to adapt to circuit boards of different sizes.
[0016] Preferably, the mounting point is a third through hole that penetrates the upper surface of the extension plate. When several extension plates are folded, the third through holes on adjacent extension plates are interconnected. When folded onto the first plate, the third through hole and the first through hole are interconnected, and the fixing bolt is inserted through the third through hole.
[0017] By adopting the above technical solution, when there are a large number of extension plates, since the extension plates are rotatably connected, in order to reduce the impact on the movement of the robotic arm when the extension plates rotate freely, the third perforations on the folded extension plates are interconnected so that fixing bolts can be inserted through the third perforations of several extension plates, thereby connecting with the support rod threadedly to adjust the position of the required sensor.
[0018] Preferably, the third perforation is provided as an oblong perforation.
[0019] By adopting the above technical solution, the third perforation is set as an oblong hole so that it can be finely adjusted along the length direction of the extension.
[0020] Preferably, the length direction of a plurality of the first plates is parallel to the width direction of the support rod, the length of the first plate is less than the width of the support rod, and the length or width of the extension plate is less than the width of the support rod.
[0021] By adopting the above technical solution, the length of the first plate is less than the width of the support rod, and the length or width of the extension plate is less than the length of the support rod, so as to reduce the possibility of the extension part being exposed on the side away from the first plate.
[0022] Preferably, the extension portion is provided with a limiting member to restrict the rotation of the extension plate.
[0023] By adopting the above technical solution, the extended plate that is connected to the first plate but is not bolted may rotate due to its rotatable connection with the first plate, which may affect the normal use of the sensor. To address this, a limiter is provided to restrict the rotation of the extended plate, thereby ensuring the stability of the sensor during use.
[0024] Preferably, anti-slip pads are provided on both opposite surfaces of the extension plate.
[0025] By adopting the above technical solution and by setting anti-slip pads, the friction between the two extended plates and the support rod or the first plate is increased, thereby improving the installation stability of the sensor during use.
[0026] In summary, this utility model has the following beneficial effects:
[0027] By providing an extension section with several mounting points that can be detachably connected to the upper surface of the support rod, the position of the sensor can be adjusted according to the size of the circuit board to be produced, thereby improving the compatibility between the sensor and circuit boards of different sizes.

[0037] The following is in conjunction with the appendix Figure 1-8This application will be described in further detail below.
[0038] This application discloses a sensor bracket structure.
[0039] Example 1:
[0040] A sensor bracket structure, as shown in the reference Figure 3 The system includes a support body 4, which comprises a first plate 5 for connecting to the upper surface of the intermediate support rod 11 of the robotic arm 1, a second plate 6 perpendicular to the first plate 5 for connecting to the sensor 3, and several fasteners 7. The first plate 5 is detachably connected to the support rod 11 via the fasteners 7, and the sensor 3 is also detachably connected to the second plate 6 via the fasteners 7.
[0041] In this embodiment, the length direction of the first plate 5 is parallel to the length direction of the support rod 11, and the width direction of the first plate 5 is parallel to the width direction of the support rod 11. A first through hole 51 is formed through the upper surface of the first plate 5. The first through hole 51 is set in an oblong shape along the width direction of the first plate 5, and several first through holes 51 are spaced apart along the length direction of the first plate 5, specifically two. The fixing member 7 specifically includes a fixing bolt 71, which passes through the first through hole 51. The upper surface of the support rod 11 has a threaded hole (not shown in the figure) for threaded connection of the fixing bolt 71, so as to install the sensor 3 bracket on the support rod 11.
[0042] The sensor 3 is located on the side of the second plate 6 away from the first plate 5 and close to the suction cup 2. The second plate 6 has a second through hole extending along its thickness direction, and two second through holes are spaced apart along the width direction of the second plate 6. The sensor 3 has two protruding fixing rings 31, each corresponding to one of the two second through holes. The fixing component 7 also includes a fixing nut 72, wherein a fixing bolt 71 passes through the fixing rings 31 and the second through hole to be threadedly connected to the fixing nut 72, thereby mounting the sensor 3 to the second plate 6 and to the support rod 11.
[0043] Furthermore, to improve the compatibility between the sensor 3 and circuit boards of different sizes, in this embodiment, the first plate 5 is provided with an extension portion 8 in a direction away from the sensor 3. The extension portion 8 is also detachably connected to the support rod 11 via a fastener 7. The extension portion 8 is provided with mounting points 81 that are detachably connected to the upper surface of the support rod 11. Several mounting points 81 are spaced apart along the length direction of the extension portion 8. In this embodiment, the extension portion 8 is an extension plate 82. The length direction of the extension plate 82 is parallel to the length direction of the first plate 5. The extension plate 82 and the first plate 5 are integrally formed, and one end of the extension plate 82 away from the first plate 5 is exposed on the support rod 11. In this embodiment, the mounting point 81 is a third through hole penetrating the upper surface of the extension plate 82. The third through hole is also oblong-shaped. Several third through holes are spaced apart along the length direction of the extension plate 82, and two are spaced apart along the width direction of the extension plate 82.
[0044] Reference Figure 3 , Figure 4 Furthermore, several third through holes can be connected and connected to the first through hole 51 originally set on the first plate 5 to form a strip hole. To improve installation stability, a first toothed groove 12 is opened on the upper surface of the support rod 11, and a second toothed groove 52 that engages with the first toothed groove 12 is opened on the lower surface of the first plate 5 near the support rod 11. A second toothed groove 52 that engages with the first toothed groove 12 is also opened on the extension plate 82 to limit the possibility of the first plate 5 sliding along the width direction of the support rod 11.
[0045] The implementation principle of a sensor bracket structure in this application embodiment is as follows: according to the requirements, the extension plate 82 is moved to align the corresponding third through hole with the threaded hole, and then the fixing bolt 71 is passed through the third through hole to be threadedly connected with the threaded hole, so as to adjust the position of the sensor 3 according to the size of the circuit board to be produced, thereby improving the compatibility between the sensor 3 and circuit boards of different sizes.
[0046] Example 2:
[0047] Reference Figure 5 , Figure 6The difference from Embodiment 1 is that the extension portion 8 includes several extension plates 83 rotatably connected in sequence. The extension plate 83 near the first plate body 5 is rotatably connected to the first plate body 5. The length or width of the extension plate 83 is less than the width of the support rod 11. Specifically, depending on the number of extension plates 83 provided, the extension plate 83 can be rotatably folded to the first plate body 5 or the other extension plates 83, and the folded state is S-shaped. In this embodiment, the first plate body 5 and the extension plates 83, as well as adjacent extension plates 83, can be rotatably connected by hinges. The hinges can be 180-degree folding hinges, 360-degree folding hinges, or foldable plastic hinges, to connect the first plate body 5 and the extension plates 83 and adjacent extension plates 83, depending on the requirements. The provided second toothed groove 52 can extend to the surface of the extension plate 83 near the support rod 11, that is, the lower surface after unfolding.
[0048] It should be noted that when the hinge is a 180-degree folding hinge, during use, the extension plate 82, which is not an extension of the first plate 5, may rotate under the first plate 5. This may cause a height difference between the first plate 5 and the support rod 11, affecting the height direction of the sensor 3. To address this, an anti-slip pad 84 can be fixedly connected to the surface of the extension plate 83. In this embodiment, the anti-slip pad 84 is made of plastic, rubber, or foam, depending on the requirements. Furthermore, during subsequent use, the connection between the anti-slip pad 84 and the first toothed groove 12 ensures relatively high installation strength for the sensor 3, making slippage less likely. If the impact is significant, a 360-degree folding hinge can be used, or a foldable plastic material can be used.
[0049] At this time, the third perforation is set on the extension plate 83. When several extension plates 83 are folded, the third perforations on adjacent extension plates 83 are connected to each other. When folded onto the first plate 5, the third perforation and the first perforation 51 are connected, and the fixing bolt 71 is inserted through the third perforation.
[0050] Reference Figure 7 , Figure 8 Furthermore, the extension plate 83, which is connected to the first plate 5 but is not fixed by bolts 71, may rotate and affect the normal use of the sensor 3 because it is rotatably connected to the first plate 5. In this embodiment, a limiting member 9 is provided on the extension part 8 to restrict the rotation of the extension plate 83.
[0051] The limiting member 9 can be a dovetail clamp, which can clamp the sides of the first plate 5 and the extension plate 83, or clamp the sides of the two extension plates 83. It can be set on both sides to increase the clamping effect.
[0052] In this embodiment, the limiting member 9 specifically includes a first limiting plate 91, a second limiting plate 92 disposed below the first limiting plate 91, and a connecting plate 93 fixedly connected to the first limiting plate 91 and the second limiting plate 92. The first limiting plate 91 abuts against the upper surface of the first plate body 5, and the second limiting plate 92 abuts against the lower surface of the first plate body 5. The length of the first limiting plate 91 is longer than the length of the second limiting plate 92 and extends to the upper surface of the extension portion 8. A fourth through hole is provided through the second limiting plate 92, and several fourth through holes are spaced apart along the length direction of the second limiting plate 92 for the fixing bolt 71 to pass through. It should be noted that due to the thickness of the hinge itself, there may be a gap between the limiting plate and the first plate body 5 or the extension plate 83. To address this, an anti-slip pad 84 or a second toothed groove 52 can be provided on the surface of the first limiting plate 91 near the first plate body 5, depending on the requirements, thereby improving installation stability.
[0053] It should be noted that there may be two first plates 5 and two second plates 6. The two first plates 5 are arranged close to each other, and the extension 8 is arranged between the two first plates 5 and connected to the two first plates 5.
[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
