Technical Field

[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to a support device, a robotic arm, and PCB processing equipment. Background Technology

[0002] The existing drilling rig is equipped with an automatic loading and unloading system. The robotic arm picks up the plates from the semi-finished material bin and sends them to the main platform for processing. After processing, the robotic arm picks up the plates and puts them into the finished product bin.

[0003] After mechanical drilling, PCBs are often riddled with through-holes. When existing robotic arms use suction cups to grasp PCBs, if some suction cups cover these through-holes, the negative pressure environment is disrupted, causing a significant weakening or even complete loss of suction power in some cups. Once the robotic arm picks up the PCB, the reduced suction power due to the through-holes becomes apparent during movement, easily leading to production anomalies such as PCBs falling off and becoming unusable. Summary of the Invention

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1 to 5As shown, an embodiment of the present invention provides a support device 100, including a driving member 1, a first connecting member 2, a support member 3 and a first connecting rod 4; the driving member 1 includes a housing 11 and a driving shaft 12, the housing 11 is adapted to connect a robot arm, the first connecting member 2 is installed on the housing 11 of the driving member 1 or the robot arm, one end of the first connecting rod 4 is rotatably connected to the first connecting member 2, and the other end of the first connecting rod 4 is connected to the support member 3.

[0021] The drive shaft 12 can drive the first link 4 to rotate, so that the support 3 is supported under the material plate 500.

[0022] The other end of the first link 4 is connected to the support member 3. The drive shaft 12 drives the first link 4 to rotate, which in turn causes the position of the support member 3 to change. After the robot arm finishes picking up the material, when the drive shaft 12 drives the first link 4 to rotate inward towards the material plate, the support member 3 moves inward with the end of the first link 4, eventually extending into the space below the material plate 500. At this time, the top surface of the support member 3 is in contact with the bottom surface of the material plate 500, forming a support for the material plate and preventing the material plate from falling during the movement of the robot arm.

[0023] In this embodiment, when the suction force of the robot's suction cup weakens, the support member 3 supports the material plate, making it less likely to fall off and reducing the possibility of the material plate falling off and being damaged or scrapped.

[0024] In one embodiment, one end of the first connecting rod 4 is rotatably connected to the first connecting member 2 about the first axis a. The drive shaft 12 can drive the first connecting rod 4 to rotate about the first axis a, thereby moving the support member 3 between a first position and a second position. When the support member 3 is in the first position, it can avoid the material plate 500 when the robot arm picks up or puts down materials. When the support member 3 is in the second position, it supports the material plate 500 from below.

[0025] When the drive shaft 12 drives the first connecting rod 4 to rotate outward of the material plate 500, the support member 3 can move upward and outward in the vertical direction along with the end of the first connecting rod 4, so that the support member 3 stays at the first position. At this time, the support member 3 is above the material plate and does not contact the material plate 500. When the robot arm removes the material plate 500, the support member 3 does not interfere with the material plate 500.

[0026] When the drive shaft 12 drives the first connecting rod 4 to rotate inward toward the material plate, the support member 3 moves downward and inward in the vertical direction along with the end of the first connecting rod 4, gradually passing over the edge of the material plate from above, and finally extending into the space below the material plate 500 (i.e., moving from the first position to the second position), so that the support member 3 can support the material plate.

[0027] In practical applications, the supporting device 100 is mounted on a robotic arm, which is equipped with an adsorption unit 300. When the robotic arm picks up material, the support member 3 is in the first position, above the material plate. The adsorption unit 300 can pick up and place the material plate without interfering with the robotic arm's operation. After the adsorption unit 300 finishes picking up material, the drive member 1 moves the support member 3 to the second position. At this position, the support member 3 is below the material plate, supporting it and preventing it from falling when the adsorption unit 300's suction weakens. Figure 4 The diagram shown is a schematic of the support member 3 supporting the material plate.

[0028] In one embodiment, the driving component 1 is a cylinder, the housing 11 is the cylinder body, and the driving shaft 12 is a piston rod that can extend and retract along the cylinder body. The first connecting component 2 is mounted on the cylinder body or the robotic arm, and the end of the first connecting component 2 away from the cylinder body is rotatably connected to the first connecting rod 4 about the first axis a. When the piston rod extends or retracts, it can apply a pushing or pulling force to the first connecting rod 4, driving the first connecting rod 4 to rotate about the first axis a, thereby driving the support component 3 to switch positions.

[0029] In one embodiment, such as Figure 1 , Figure 2 As shown, the other end of the first connecting rod 4 is rotatably connected to the support member 3 about the second axis b, and the first axis a is parallel to the second axis b. The drive shaft 12 can drive the first connecting rod 4 to rotate about the first axis a, and drive the support member 3 to rotate relative to the first connecting rod 4 about the second axis b.

[0030] By rotating the first link 4 away from the first connector 2 and the support 3, when the first link 4 rotates around the first axis a, the support 3 can not only move with the first link 4, but also rotate relative to the first link 4, so that the support 3 can adjust its own posture and adapt to more complex working scenarios.

[0031] As an example, one end of the first link 4 is rotatably connected to the first connector 2 about the first axis a, and the other end of the first link 4 is rotatably connected to the support 3 about the second axis b. Under the driving action of the drive member 1, the first link 4 rotates relative to the first connector 2 about the first axis a, and the support 3 moves with the first link 4. At the same time, the support 3 can rotate relative to the first link 4 about the second axis b.

[0032] In one embodiment, such as Figure 1 , Figure 2 As shown, the support device 100 also includes a second link 5, one end of which is connected to the drive shaft 12, and the other end of which is connected to the first link 4. The drive member 1 can drive the first link 4 to rotate around the first axis a through the second link 5.

[0033] The second link 5 connects the drive shaft 12 and the first link 4. The drive shaft 12 can drive the second link 5 to move, thereby driving the first link 4 to rotate. The drive shaft 12 performs linear motion (extension and retraction of the piston rod), which is converted into rotational motion of the first link 4 by the second link 5. Furthermore, by using the second link 5 as an intermediate transmission component, the drive component 1 can remain stationary throughout the entire movement, without occupying additional space, making the overall structure of the support device 100 more compact.

[0034] In one embodiment, one end of the second link 5 is rotatably connected to the middle of the first link 4 about the third axis c, and the other end of the second link 5 is rotatably connected to the drive shaft 12 of the drive member 1 about the fourth axis d. The third axis c is located between the first axis a and the second axis b.

[0035] In the first position, such as Figure 5 As shown, the first link 4 extends along the first direction, and the second link 5 extends along the second direction. In the second position, as... Figure 4 As shown, the first link 4 extends along the second direction, and the second link 5 extends along the first direction, with the first direction intersecting the second direction.

[0036] The linear motion of the drive shaft 12 of the drive component 1 can drive the second link 5 to rotate relative to the drive shaft 12 of the drive component 1 around the fourth axis d. Since the other end of the second link 5 is rotatably connected to the middle of the first link 4, the second link 5 will exert a pushing and pulling force on the first link 4, causing the first link 4 to rotate around the fixed first axis a, thereby realizing the switching between the first position and the second position.

[0037] Among them, such as Figure 2 As shown, the first direction X is horizontal, the second direction Y is vertical, and the drive shaft 12 of the drive member 1 moves in the vertical direction. When the support member 3 is in the first position, the first connecting rod 4 is placed horizontally, the second connecting rod 5 is placed vertically, and at this time, the support member 3 is tilted.

[0038] When the drive shaft 12 of the drive member 1 moves downward, it can push the second link 5 downward. Due to the interference of the first link 4 on the second link 5, while the second link 5 moves downward, one end of the second link 5 rotates relative to the drive shaft 12 of the drive member 1 around the fourth axis d, and the other end of the second link 5 rotates relative to the first link 4 around the third axis c. At the same time, the second link 5 will push the first link 4, causing the first link 4 to rotate around the first axis a. The support member 3 will move downward and inward, so that the support member 3 passes over the edge of the material plate 500 and moves from above the material plate to below the material plate, forming support for the material plate 500. Finally, the support member 3 moves from the first position to the second position.

[0039] After reaching the second position, the first link 4 is placed vertically and the second link 5 is placed horizontally.

[0040] Conversely, when the drive shaft 12 of the drive component 1 moves upward, it will pull the second link 5 upward. Due to the interference of the first link 4 on the second link 5, while the second link 5 moves upward, one end of the second link 5 rotates relative to the drive shaft 12 of the drive component 1 around the fourth axis d, and the other end of the second link 5 rotates relative to the first link 4 around the third axis c. At the same time, the second link 5 will pull the first link 4, causing the first link 4 to rotate around the first axis a. The support component 3 will move outward and upward, realizing the movement of the support component 3 from the second position to the first position.

[0041] In this embodiment, the fourth axis d is located at the end of the second connecting rod 5 near the driving member 1, the third axis c is located at the connection between the middle of the first connecting rod 4 and the end of the second connecting rod 5 away from the driving member 1, the first axis a is located at the end of the first connecting rod 4 near the first connecting member 2, and the second axis b is located at the end of the first connecting rod 4 away from the first connecting member 2. During the position change of the support member 3, the third axis c is located between the first axis a and the second axis b, and the positional relationship of the three remains unchanged. When the support member 3 is in the first position, the first connecting rod 4 is placed horizontally, the second connecting rod 5 is placed vertically, the projections of the first axis a, the second axis b, and the third axis c in the vertical direction overlap, and the projections of the third axis c and the fourth axis d in the horizontal direction overlap.

[0042] When the support member 3 is in the second position, the first connecting rod 4 is placed vertically, the second connecting rod 5 is placed horizontally, the projections of the first axis a, the second axis b and the third axis c in the horizontal direction overlap, and the projections of the third axis c and the fourth axis d in the vertical direction overlap.

[0043] In one embodiment, such as Figure 1 , Figure 2 As shown, the support device 100 also includes a second connector 6 and a third link 7. The second connector 6 is mounted on the drive shaft 12 of the drive member 1. One end of the third link 7 is rotatably connected to the second connector 6 about the fifth axis e. One end of the third link 7 can rotate relative to the second connector 6. The other end of the third link 7 is rotatably connected to the support member 3 about the sixth axis f. The other end of the third link 7 can rotate relative to the support member 3.

[0044] The third link 7 connects the second connector 6 and the support 3, which can constrain the support 3 and prevent irregular swaying when the support 3 is connected to the second link 5 at a single point. In addition, since the second connector 6 and the second link 5 are both connected to the drive shaft 12 of the drive member 1, when the drive shaft 12 of the drive member 1 moves in a straight line in the vertical direction, it can drive the second link 5 and the third link 7 to move simultaneously. The third link 7 also has a certain pushing and pulling effect on the support 3, which helps to realize the switching between the first position and the second position.

[0045] The second connecting member 6 is mounted on the drive shaft 12 of the drive member 1, and the second connecting member 6 is fixed relative to the drive shaft 12 of the drive member 1. The second connecting rod 5 is rotatably connected to one end of the second connecting member 6, and the third connecting rod 7 is rotatably connected to the other end of the second connecting member 6.

[0046] In one specific embodiment, the supporting device 100 includes a driving member 1, a first connecting member 2, a second connecting member 6, a support member 3, a first connecting rod 4, a second connecting rod 5, and a third connecting rod 7. The first connecting member 2 is connected to the fixing component of the driving member 1, and the second connecting member 6 is connected to the drive shaft 12 of the driving member 1. The first connecting member 2 extends vertically, the first connecting rod 4 connects the lower end of the first connecting member 2 and the support member 3, the second connecting rod 5 connects the second connecting member 6 and the first connecting rod 4, and the third connecting rod 7 connects the second connecting member 6 and the support member 3.

[0047] Driven by the drive component 1, the two ends of the first link 4 rotate around their respective axes, the two ends of the second link 5 rotate around their respective axes, and the two ends of the third link 7 rotate around their respective axes, so that the support component 3 can gradually return to the upright position from the tilted state and finally smoothly support the material plate 500, and gradually tilt from the horizontal support posture and finally detach from the material plate 500. In this embodiment, the links form an organic linkage through multi-axis rotation, which not only ensures the stability of the posture adjustment of the support component 3, but also ensures the switching between supporting and releasing the material plate.

[0048] In one embodiment, such as Figure 1 As shown, the support member 3 includes a connecting part 31 and a support part 32. The connecting part 31 is connected to the support part 32. The first connecting rod 4 is connected to the end of the connecting part 31 near the support part 32. The support part 32 is used to support the material plate 500.

[0049] In this embodiment, the connection between the first link 4 and the support member 3 is achieved by adapting the connecting part 31 to the connection requirements of the first link 4. The support part 32 can abut against the bottom of the material plate 500 to provide support.

[0050] The third link 7 is rotatably connected to the end of the connecting part 31 away from the support part 32.

[0051] In one embodiment, a protective pad 321 is provided on the support portion 32 so that when the support portion 32 comes into contact with the material plate 500, it can protect the material plate from being scratched and reduce the occurrence of local indentations on the surface of the material plate.

[0052] Preferably, the protective gasket 321 is a rubber gasket, a silicone gasket, or a soft plastic gasket.

[0053] In one embodiment, such as Figure 1 , Figure 2 As shown, the support device 100 also includes a mounting plate 8, the fixed part of the drive component 1 is connected to the mounting plate 8, and the mounting plate 8 is connected to the robot arm. The mounting plate 8 can provide a stable mounting base for the drive component 1, realize the installation of the drive component 1 on the robot arm, and the mounting position of the drive component 1 can be flexibly adjusted through the mounting plate 8.

[0054] Among them, the driving component 1 is a cylinder, and the cylinder body is fixed on the mounting plate 8.

[0055] On the other hand, such as Figure 3 As shown, this utility model embodiment provides a robotic arm, including a mounting frame 200, an adsorption unit 300, and a plurality of support devices 100 according to any of the above embodiments. The adsorption unit 300 and the support devices 100 are disposed on the mounting frame 200. The adsorption unit 300 is used to pick up the material plate 500, and the support devices 100 are used to support the material plate 500 picked up by the adsorption unit 300.

[0056] The adsorption unit 300 can adsorb the material plate 500. When the adsorption unit 300 adsorbs the material plate 500, the support member 3 is in the first position and will not interfere with the adsorption unit 300's material suction or discharge operation. After the adsorption unit 300 picks up the material plate, the first connecting rod 4 is driven by the driving member 1 to move, so that the support member 3 moves to the second position and supports the material plate 500, preventing the material plate 500 from falling when the suction force of the adsorption unit 300 weakens or disappears during the robot's transport of the material plate.

[0057] In this embodiment, multiple supporting devices 100 can enhance the support of the material plate 500 and prevent the material plate from falling. Here, "multiple" refers to two or more.

[0058] In one embodiment, multiple adsorption units 300 are provided, arranged around the mounting frame 200. The adsorption effect on the material plate 500 is increased by multiple adsorption units 300. Generally, the multiple adsorption units 300 are distributed in the outer edge area and the middle position of the material plate to ensure uniform adsorption of the material plate 500.

[0059] In one embodiment, the robotic arm further includes a lifting assembly 400, the output end of which is connected to the mounting frame 200. The lifting assembly 400 can drive the mounting frame 200 to rise and fall. When the lifting assembly 400 drives the mounting frame 200 to rise, the adsorption unit 300 moves away from the material plate 500; when the lifting assembly 400 drives the mounting frame 200 to fall, the adsorption unit 300 moves closer to the material plate 500, enabling the adsorption unit 300 to perform a suction operation.

[0060] In this embodiment, the lifting component 400 can be a linear module motor or a cylinder. The lifting component 400 is an existing structure and will not be described in detail here.

[0061] On the other hand, this utility model provides a PCB processing equipment, including a worktable, a processing body and a robot arm of any of the above embodiments. The processing body is used to process the material board 500 on the worktable, and the robot arm is used to pick up the material board 500 onto the worktable and to drive the material board 500 away from the worktable after the processing body has finished processing.

[0062] After the suction unit 300 of the robotic arm picks up the material plate 500, it transfers the material plate 500 to the worktable. The processing body can then drill holes in the material plate 500. After processing, the robotic arm unloads the material. In this embodiment, the suction unit 300 enables the gripping and releasing of the material plate 500. After the suction unit 300 picks up the material plate, the robotic arm moves towards the worktable. Multiple supporting devices 100 support the material plate to prevent it from falling, allowing the material plate 500 to be smoothly transported to the worktable or from the worktable to the next work station.

[0063] In one embodiment, the PCB processing equipment is a drilling machine or a milling machine.

[0064] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
