[0002] Currently, the production and manufacturing of most products are basically completed on automated equipment. Due to the large number of components of the products, it is necessary to position the products on the automated equipment to ensure the assembly accuracy of the products. Currently, the common positioning method is to place the products on a fixture / jig that is relatively stationary with respect to the automated equipment. The fixture / jig has positioning holes that are shaped according to the product to achieve the positioning of the product on the fixture / jig. Generally, the shaped positioning holes and the product are in clearance fit. Therefore, once the automated equipment vibrates due to inevitable reasons, the position of the product in the fixture / jig may change, resulting in inaccurate positioning. The change in the position of the product will cause the production and manufacturing reference to be inconsistent, and then the phenomenon of poor product assembly will occur.

[0032] An auxiliary positioning mechanism 100 provided by the present invention is used for an automated production device and is specifically used to fix the product 70 in the positioning hole to prevent the product 70 and the positioning hole from being misaligned due to vibration.

[0033] Refer to Figure 1, in the first aspect of the present invention, an auxiliary positioning mechanism 100 is provided, including a substrate 10 and a positioning mechanism. Specifically, the substrate 10 is movably arranged corresponding to the positioning hole of the automated production equipment; the positioning mechanism includes a gas adsorption component 20 and a magnetic adsorption component 30 arranged on the substrate 10, wherein the substrate 10 can move relative to the positioning hole according to the shape and / or material characteristics of the product 70, so that the gas adsorption component 20 and the magnetic adsorption component 30 are activated separately or simultaneously to fix the product 70 in the positioning hole.

[0034] Specifically, a tooling 60 is provided on the automated production equipment. The tooling 60 has a positioning hole for receiving and defining the product 70. A hollow area corresponding to the positioning hole is also formed on the tooling 60, and at least part of the positive projection of the hollow area coincides with the positioning hole and / or is arranged around the outer periphery of the positioning hole.

[0035] The substrate 10 is formed into a plate structure with a certain thickness, and the gas adsorption component 20 and the magnetic adsorption component 30 arranged corresponding to the positioning hole are provided thereon. The gas adsorption component 20 has an adsorption function and can fix the product 70 in the positioning hole by adsorbing the product 70 to be fixed. The magnetic adsorption component 30 has a magnetic adsorption function and can attract the product 70 made of a specific material to fix the product 70 in the positioning hole.

[0036] The substrate 10 is arranged corresponding to the automated production equipment and can drive the gas adsorption component 20 and the magnetic adsorption component 30 to move relative to the positioning hole together to adjust the gas adsorption component 20 and the magnetic adsorption component 30 to the optimal positions. It should be noted that the relative movement of the substrate 10 includes moving along the horizontal axis, the vertical axis and / or the vertical axis. The optimal position refers to the positions of the gas adsorption component 20 and the magnetic adsorption component 30 in the optimal fixing scheme determined based on the shape and / or material characteristics of the product 70 to be fixed. The optimal fixing scheme includes fixing the product 70 only by using the gas adsorption component 20, fixing the product 70 only by using the magnetic adsorption component 30, and using the gas adsorption component 20 and the magnetic adsorption component 30 to cooperate to fix the product 70. By moving the substrate 10 to the optimal position and implementing the optimal fixing scheme to fix the product 70 in the positioning hole, the relative movement between the product 70 and the automated production equipment can be avoided, thereby ensuring the unity of the reference in the subsequent assembly process of the product 70 and facilitating the subsequent assembly.

[0037] In an embodiment of the present invention, an auxiliary positioning mechanism 100 is added corresponding to the positioning holes of the automated production equipment, and the auxiliary positioning mechanism 100 includes a substrate 10 and a positioning mechanism. The positioning mechanism includes a gas adsorption assembly 20 and a magnetic adsorption assembly 30. Thus, by moving the substrate 10, the gas adsorption assembly 20 and / or the magnetic adsorption assembly 30 can be adsorbed and connected to the product 70 placed in the positioning hole, thereby fixing the product 70 in the positioning hole. In this way, the relative movement between the product 70 and the automated production equipment can be avoided, and further, the reference can be unified during the subsequent assembly process of the product 70, thus facilitating the subsequent assembly.

[0038] In one embodiment, the gas adsorption assembly 20 includes a suction cup 22 provided on the substrate 10 and a vacuum generator 21 communicated with the suction cup 22. The suction cup 22 is adapted to be adsorbed and connected to the product 70.

[0039] Specifically, the suction cup 22 is made of rubber material. It is provided on the side of the substrate 10 facing the positioning hole and is connected to the vacuum generator 21 through a connecting pipe. During adsorption, the suction cup 22 contacts the outer surface of the product 70. At the same time, the vacuum generator 21 works and evacuates the air between the suction cup 22 and the product 70, so that the suction cup 22 is adsorbed on the product 70. And since the suction cup 22 is relatively fixed to the substrate 10, the product 70 is also relatively fixed to the substrate 10 and the positioning hole.

[0040] In one embodiment, the magnetic adsorption assembly 30 includes a magnetic component provided on the substrate 10 and an ejector cylinder 31 connected to the substrate 10. The magnetic member 33 is adapted to be magnetically adsorbed and connected to the product 70, and the ejector cylinder 31 is adapted to provide a two-way thrust when connecting and separating the magnetic member 33 and the product 70.

[0041] Specifically, the magnetic component can be embedded in the substrate 10 or pasted on the side of the substrate 10 facing the positioning hole. The magnetic component has magnetism and can adsorb the product 70 containing metals such as iron, cobalt, and nickel through magnetic force. The ejector cylinder 31 is a two-way ejector cylinder 31 with two-way ejector posts. One ejector post is connected to the substrate 10, and the other ejector post is adapted to contact the product 70. Thus, when it is necessary to separate the magnetic component and the product 70, the ejector cylinder 31 is activated and applies forces to the substrate 10 and the product 70 at the same time. This force overcomes the magnetic force between the magnetic component and the product 70 to separate the magnetic component and the product 70. And when it is necessary to use the magnetic adsorption assembly 30 for adsorption, the two ejector posts of the ejector cylinder 31 contract towards each other to avoid interfering with the connection between the magnetic component and the product 70.

[0042] In one embodiment, the suction cups 22 are a plurality of suction cups 22 arranged in an array. The plurality of suction cups 22 are communicated with the vacuum generator 21 through an adjustable air path, and the plurality of suction cups 22 can dynamically adjust the adsorption area according to the shape and size of the product 70.

[0043] In this embodiment, suction cups 22 arranged in an array are provided and connected to a vacuum generator 21 through an adjustable air path, so that fine control of the suction cups 22 can be achieved, and thus vacuum adsorption control of regular products 70 and irregular products 70 can be realized. At the same time, the mutual interference between the magnetic adsorption assembly 30 and the suction cups 22 can also be reduced.

[0044] In one embodiment, the magnetic member 33 is an electromagnetic member with adjustable magnetic force, and the electromagnetic member can adjust the magnetic force based on the product 70 to fix the product 70 in the positioning hole.

[0045] In this embodiment, by setting the electromagnetic member as an electromagnetic member with adjustable magnetic force, the electromagnetic member adjusts its magnetism based on the size of the product 70 and / or the proportion of the mass of metals such as iron, cobalt, and nickel in the product 70 that can be adsorbed by the electromagnetic member, so as to adjust the magnetic attraction force between the electromagnetic member and the product 70, thereby improving the reliability of the magnetic adsorption assembly 30. Specifically, when the shape of the product 70 is larger or the proportion of the mass of metals such as iron, cobalt, and nickel in the product 70 that can be adsorbed by the electromagnetic member is smaller, the electromagnetic force of the electromagnetic member can be increased, thereby increasing the magnetic attraction force between the adjusted electromagnetic member and the product 70. Conversely, the electromagnetic force of the electromagnetic member is reduced, thereby reducing the magnetic attraction force between the adjusted electromagnetic member and the product 70.

[0046] In one embodiment, the positioning mechanism further includes a clamping assembly 40. The clamping assembly 40 includes a clamping cylinder 41 connected to the substrate 10 and an adaptive jaw 42 provided at the end of the clamping cylinder 41. The clamping cylinder 41 is adapted to drive the adaptive jaw 42 to deform according to the outer contour of the product 70 and clamp and fix the product 70.

[0047] Specifically, the clamping cylinder 41 and the adaptive jaw 42 provided at the end of the clamping cylinder 41 together form a pneumatic jaw (also known as a pneumatic finger) and can drive the adaptive jaw 42 to clamp the product 70 from the side of the product 70. The adaptive jaw 42 can be a parallel jaw, a swing jaw, or a three-point jaw. In this embodiment, it is preferably a parallel jaw.

[0048] In this embodiment, by providing the clamping assembly 40, the ability of the auxiliary positioning mechanism 100 to fix the product 70 in the positioning hole is further improved, thereby further improving the reliability of the auxiliary positioning mechanism 100.

[0049] In one embodiment, avoidance holes corresponding to the adaptive jaw 42 are provided on both the substrate 10 and the automated production equipment, and the end of the adaptive jaw 42 away from the clamping cylinder 41 is located in the avoidance hole.

[0050] Specifically, there are two avoidance holes on the substrate 10, which are respectively arranged on both sides of the substrate 10, so as to form a notch on the substrate 10 for the adaptive gripper 42 to move. The avoidance holes on the automated production equipment are located on the outer periphery of the positioning cavity, so that the adaptive gripper 42 can insert and clamp the product 70 located in the positioning cavity.

[0051] In one embodiment, the ejecting cylinder 31 is a sliding table cylinder, and the clamping cylinder 41 is installed on the sliding table of the ejecting cylinder 31.

[0052] In one embodiment, a position adjusting mechanism 50 is further included. The position adjusting mechanism 50 is connected to the substrate 10 and is adapted to adjust the position of the substrate 10 to be adapted to the positioning cavity.

[0053] Specifically, the adjusting mechanism can be used to realize the up-down, left-right and front-back position adjustment of the substrate 10, and then adjust the positioning mechanism corresponding to the product 70 to a position corresponding to the product 70, so as to facilitate the fixation of the product 70.

[0054] Through the above settings, the adjusting mechanism can have the adjusting ability in three directions of X, Y and Z, which is convenient for adjusting the substrate 10.

[0055] In one embodiment, the position adjusting structure includes a bottom plate 51, an X-direction cylinder 52, a Y-direction cylinder 53 and a Z-direction cylinder 54. The X-direction cylinder 52 is connected to the bottom plate 51, the Y-direction cylinder 53 is connected to the X-direction cylinder 52, and the Z-direction cylinder 54 is connected between the Y-direction cylinder 53 and the substrate 10.

[0056] Specifically, the X-direction cylinder 52, the Y-direction cylinder 53 and the Z-direction cylinder 54 are all sliding table cylinders. Among them, the cylinder barrel of the X-direction cylinder 52 is installed on the bottom plate 51, the Y-direction cylinder 53 is connected to the sliding table of the X-direction cylinder 52, the Z-direction cylinder 54 is connected to the sliding table of the Y-direction cylinder 53, and the substrate 10 is fixedly connected to the sliding table of the Z-direction cylinder 54.

[0057] At the same time, the ejecting cylinder 31 is also connected to the sliding table of the Z-direction cylinder 54. In this way, the two relatively sliding parts of the ejecting cylinder 31 can respectively act on the substrate 10 and the product 70, so as to realize the separation of the two.

[0058] Furthermore, a ejecting rod 32 is formed at one end of the ejecting cylinder 31 for adapting to the product 70. The ejecting rod 32 is located between the two adaptive grippers 42, and the sliding table of the ejecting cylinder 31 is connected to the ejecting rod 32 through an L-shaped adapter.

[0059] In the second aspect of the present invention, an automated production device is further provided, which includes the auxiliary positioning mechanism 100 of any one of the above. The auxiliary positioning mechanism 100 refers to the above embodiments and will not be elaborated here. Since the automated production device in this embodiment includes the above auxiliary positioning mechanism 100, it also has at least the beneficial effects of the above auxiliary positioning mechanism 100.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
