[0028] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] The utility model discloses a kind of mechanical arm large arm installation protection devices, including support main body 1 and support block 2. Figure 1 Support main body 1 is provided with first end face 11 and second end face 12, second end face 12 is provided with installation through hole 13. Support block 2 is arranged on second end face 12, and the bottom surface of support block 2 is parallel to second end face 12, and the end of installation through hole 13 away from support block 2 is provided with opening.

[0030] Please refer to Figures 1 to 4 In the embodiment, mechanical arm large arm 4 is placed by support main body 1. Therefore, support main body 1 is provided with first end face 11 and second end face 12, first end face 11 is used to place mechanical arm large arm 4. And mechanical arm large arm 4 is placed on first end face 11 by the plane of bottom, so that mechanical arm large arm 4 is attached to first end face 11, to ensure that first end face 11 is parallel to mechanical arm large arm 4.

[0031] Then the substrate 3 is placed below the support body 1, and the second end surface 12 abuts against the substrate 3. Similarly, the substrate 3 is attached to the second end surface 12 by the top plane, so that the substrate 3 and the second end surface 12 are parallel to each other. Because of the first end surface 11 and the second end surface 12, the substrate 3 is guaranteed to be parallel to the robot arm 4.

[0032] At this time, the robot arm 4 is placed on the support body 1, and the support body 1 is pressed down by gravity. The substrate 3 is placed below the support body 1, so the support body 1 transmits the force to the substrate 3, thereby generating pressure on the substrate 3. Then, by pressing the substrate 3 with the robot arm 4, it is possible to cause bruising to the substrate 3.

[0033] In the present embodiment, the support block 2 is provided on the second end surface 12 below the support body 1, and the support block 2 is located on the same side of the support body 1 as the substrate 3. The support block 2 is connected to the second end surface 12, so that the support body 1 is supported by the support block 2. When the robot arm 4 is placed on the first end surface 11 of the support body 1, the robot arm 4 presses the support body 1 downward by gravity, and then the support body 1 transmits the pressure downward to the support block 2, and the support block 2 provides upward support force to counteract the gravity of the robot arm 4.

[0034] Generally, first, the substrate 3 is placed on the table, and then the robot arm mounting protection device is placed on the substrate 3 with the second end surface 12 facing the substrate 3. After the robot arm mounting protection device is connected to the substrate 3 in alignment, the robot arm 4 is placed on the first end surface 11. When the robot arm 4 is pressed down, the robot arm mounting protection device and the substrate 3 are brought down together. In order to ensure that the robot arm mounting protection device contacts the table first and provides support force, the height of the support block 2 is designed to be greater than or equal to the height of the substrate 3. Because the support block 2 and the substrate 3 are both provided on the second end surface 12, i.e., in the height direction, the upper end of the support block 2 and the upper end of the substrate 3 are both on the second end surface 12, so when the second end surface 12 brings the support block 2 and the substrate 3 down together, the support block 2 will touch the table first, thereby providing support force through the support block 2.

[0035] It can be understood that generally the upper and lower surfaces of the substrate 3 are parallel, and the upper and lower surfaces of the substrate 3 are flat. Therefore, when the substrate 3 is placed on the table, the lower surface of the substrate 3 is attached to the table. Similarly, the bottom surface of the support block 2 is also flat, so when the support block 2 is placed on the table, the bottom surface of the support block 2 is also attached to the table. The bottom surface of the support block 2 is parallel to the second end surface 12, so the second end surface 12 is parallel to the lower surface of the substrate 3, and the second end surface 12 is also parallel to the upper surface of the substrate 3.

[0036] Meanwhile, the robot arm 4 is placed on the first end surface 11, so the robot arm 4 is parallel to the first end surface 11. Since the first end surface 11 is parallel to the second end surface, the second end surface 12 is parallel to the upper surface of the substrate 3, so the robot arm 4 is parallel to the upper surface of the substrate 3, and then the installation can be performed.

[0037] The mounting through hole 13 is formed in the second end surface 12, so during the installation, the connecting piece passes through the mounting through hole 13 to connect the robot arm 4 and the substrate 3 together. Then after the installation is completed, the connecting piece will abut against the inner wall of the mounting through hole 13, so that the robot arm installation protection device cannot be taken out. In the embodiment, an opening is arranged at the end of the mounting through hole 13 away from the support block 2. Since the support block 2 will abut against the substrate 3 to limit the position, the robot arm installation protection device can only be taken out in the direction away from the substrate 3 along the support block 2. Then the opening arranged at the end of the mounting through hole 13 away from the support block 2 can make the connecting piece separate from the support body 1 through the opening when the robot arm installation protection device is taken out, and the connecting piece and the support body 1 will not abut against each other.

[0038] Then in the embodiment, the substrate 3 and the support block 2 are placed on the table, the support body 1 is placed on the support block 2, and the robot arm 4 is placed on the support body 1, so that the parallelism between the robot arm 4 and the substrate 3 can be ensured, and the installation position accuracy of the robot arm 4 and the substrate 3 can be ensured. Then the support block 2 is used to support the robot arm 4, so that the robot arm 4 will not cause bruising to the substrate 3, and the integrity of the substrate 3 can be ensured.

[0039] In an embodiment, the robot arm installation protection device includes two support bodies 1, and each support body 1 is formed with a semicircular mounting through hole 13. The two support bodies 1 are connected in alignment, so that the two mounting through holes 13 are aligned to form a circle.

[0040] Please refer to Figure 2 and Figure 3 together. In the embodiment, the two support bodies 1 are arranged symmetrically with each other. After the substrate 3 is installed on the table, the two support bodies 1 are connected in alignment on the substrate 3 from both sides. After the positions of the two support bodies 1 and the substrate 3 are arranged accurately, the robot arm 4 is placed on the two support bodies 1, and the two support bodies 1 are pressed tightly together by the gravity of the robot arm 4, so that the positional deviation of the two support bodies 1 is avoided. Since the substrate 3 and the robot arm 4 need to have a circular through hole for connection in the embodiment, each mounting through hole 13 is semicircular.

[0041] After the two support bodies 1 are aligned and connected, the two mounting through holes 13 are combined into a circle, providing sufficient space for the connection of the substrate 3 and the robot arm 4. After the connection of the substrate 3 and the robot arm 4 is completed, the two support bodies 1 only need to be taken out from both sides between the substrate 3 and the robot arm 4.

[0042] In the embodiment, by dividing the support body 1 into two symmetrical bodies, the process of opening the mounting through hole 13 is avoided, and the taking out of the support body 1 is also simpler.

[0043] In an embodiment, the two support bodies 1 are detachably connected. In an embodiment, one of the two support bodies 1 is provided with a positioning hole, and the other is provided with a positioning pin, and the two support bodies 1 are connected by the positioning pin and the positioning hole.

[0044] In the embodiment, the two support bodies 1 are detachably connected, and the connection methods include but are not limited to mortise and tenon connection, pin shaft connection, and buckle connection, etc. Because the two support bodies 1 need to ensure accurate positioning, and then be pressed by the robot arm 4 to prevent the position deviation of the two support bodies 1. During the placement process, it is difficult for manual to align the two support bodies 1. Therefore, through the detachable connection method, the relative position of the two support bodies 1 remains accurate after connection. At the same time, after the installation of the substrate 3 and the robot arm 4 is completed, the two support bodies 1 can be detached and then separated.

[0045] Further, in the embodiment, the pin shaft connection of the two support bodies 1 is taken as an example. Along the direction of the alignment and connection of the two support bodies 1, a positioning hole (not shown in the figure) is formed on one of the support bodies 1, and a positioning pin (not shown in the figure) is arranged on the other support body 1. During installation, the positioning pin on one of the support bodies 1 is aligned with the positioning hole on the other support body 1, and the positioning pin is inserted into the positioning hole, so as to ensure the accurate positioning of the two support bodies 1 during connection.

[0046] In an embodiment, the side of the support block 2 facing the mounting through hole 13 is a circular arc side, and the support block 2 is attached to the substrate 3 through the side. In an embodiment, the side of the support block 2 is coaxial with the mounting through hole 13.

[0047] Please refer to Figures 1 to 4Since both the support block 2 and the substrate 3 are located on the second end face 12, they are arranged adjacent to each other. The mounting through hole 13 is used to connect the substrate 3 to the robotic arm 4, so the substrate 3 is located below the mounting through hole 13. The side of the support block 2 facing the mounting through hole 13, i.e., the side of the support block 2 facing the substrate 3, is arc-shaped. Because the outer contour of the substrate 3 is also arc-shaped, the support block 2 can abut against the substrate 3 through its side. Therefore, after the substrate 3 is mounted on the table, during the installation of the support block 2, the side of the support block 2 can abut against the substrate 3, thus ensuring accurate positioning of the support block 2.

[0048] Furthermore, in this embodiment, the side of the support block 2 is coaxial with the mounting through hole 13. Since the side of the support block 2 abuts against the substrate 3, the substrate 3 is also coaxial with the mounting through hole 13. Therefore, during the connection process between the substrate 3 and the robotic arm 4, the mounting through hole 13 provides more precise installation space, ensuring that the connection between the substrate 3 and the robotic arm 4 is not affected.

[0049] In one embodiment, the first end face 11 is used to support the robotic arm 4, the length of the supporting body 1 is greater than or equal to two-thirds of the length of the robotic arm 4, and the length of the supporting block 2 is greater than or equal to half the length of the supporting body 1. In one embodiment, the height of the supporting block 2 is equal to the height of the substrate 3, and the upper surface of the substrate 3 is in contact with the second end face 12.

[0050] like Figure 4 As shown, in this embodiment, the robotic arm 4 is not completely placed on the support body 1; the left side of the robotic arm 4 is suspended in the air. In this embodiment, as long as the length of the support body 1 is greater than or equal to two-thirds of the length of the robotic arm 4, it is sufficient to ensure that the robotic arm 4 will not wobble after being placed on the support body 1. Because most of the robotic arm 4 is located on the support body 1, and the suspended portion of the robotic arm 4 is small, the center of gravity of the robotic arm 4 is located on the support body 1, which enables the robotic arm 4 to remain stable.

[0051] Furthermore, in this embodiment, the length of the support block 2 is greater than half the length of the support body 1, because the support body 1 is supported by the support block 2. Similarly, in order to keep the support body 1 stable on the support block 2, it is also necessary to make most of the support body 1 located on the support block 2.

[0052] like Figure 4As shown, after the support body 1 is arranged on the substrate 3, the bottom surface of the support block 2 is in the same horizontal position as the bottom surface of the substrate 3. Since the support body 1 is supported by the support block 2, the top surface of the support block 2 is attached to the second end surface 12. Since the height of the support block 2 is equal to the height of the substrate 3, the top surface of the substrate 3 is attached to the second end surface 12. Therefore, when the robot arm mounting protection device and the substrate 3 are assembled, the upper surface of the substrate 3 is directly attached to the second end surface 12, and there is no need to use additional devices to attach the upper surface of the substrate 3 to the second end surface 12.

[0053] In an embodiment, the thickness of the support body 1 is equal to the distance between the substrate 3 and the robot arm 4. As shown, the thickness of the support body 1 in this embodiment is 0.5 mm, and the distance between the substrate 3 and the robot arm 4 is also 0.5 mm. Therefore, when the substrate 3 and the robot arm 4 are assembled, the gap between the substrate 3 and the robot arm 4 is sufficient for the support body 1 to be removed. Figure 4

[0054] In an embodiment, the first end surface 11 and the second end surface 12 are both provided with a wear-resistant protective layer. In this embodiment, the support body 1 and the support block 2 are both made of POM acetal copolymer, so as to avoid the problem of scratching and damaging the substrate 3 or the robot arm 4 by the support body 1 and the support block 2.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.​
