Description

Technical Field

[0001] The utility model relates to the field of loading anodic oxidation parts, in particular to a positioning device and a loading device for anodic oxidation parts. Background Art

[0002] When manufacturing the outer shell parts of electronic products (such as computer cases, mobile phone cases, etc.), the surface of the outer shell parts is usually subjected to anodic oxidation treatment. Anodic oxidation (electrochemical oxidation of metals or alloys) refers to the process of forming an oxide film on a metal material under the action of an externally applied current in a corresponding electrolyte and process conditions. In the existing anodic oxidation process, several metal outer shell parts are hung on the same anodic fixture by a robotic arm, and the anodic fixture plays the roles of conducting electricity, installing, and fixing. An externally applied current is applied to the anodic fixture, so as to perform anodic oxidation treatment on all the metal outer shell parts on the anodic fixture.

[0003] To ensure the unity of the robotic arm in grasping the metal outer shell parts, the position of the metal outer shell parts is limited and positioned before the robotic arm grasps the metal outer shell parts. For example, in the Chinese utility model patent with the patent name "Anode Automatic Loading and Unloading Machine" and the patent number ZL202321880292.3 applied by the applicant on July 17, 2023, after the metal outer shell parts are placed on the bottom plate, the first push rod and the second push rod move towards the first fixed side and the second fixed side, so that the metal outer shell parts can be adjusted to a unified and fixed position for the robotic arm to grasp. The first fixed side, the second fixed side, the first push rod, and the second push rod form a region that surrounds the metal outer shell parts in four directions.

[0004] In the prior art, the first fixed side, the second fixed side, the first push rod, and the second push rod surround the metal outer shell parts, that is, the fixed sides and push rods for positioning the metal outer shell parts are in contact with the outer edge of the metal outer shell parts, which easily causes scratches and other abrasions on the outer edge of the metal outer shell parts, affecting the aesthetics of the parts. For electronic products, the aesthetics of the outer shell has a great impact on the user experience, and the scratches and abrasions on the outer shell will seriously reduce the visual experience of users. Summary of the Utility Model

[0005] Aiming at the above-mentioned deficiencies or defects in the prior art, the utility model provides a positioning device for anodic oxidation parts. During the positioning process of the parts, the positioning member abuts against the inner side of the parts, avoiding scratches and abrasions on the outer side of the parts due to positioning contact and affecting the aesthetics.

[0006] To achieve the above purpose, the utility model provides a positioning device for anodic oxidation parts, including a positioning assembly. The positioning assembly includes two positioning members that move relative to each other. The end faces of the positioning members that are away from each other along the relative movement direction are contact surfaces for abutting against the inner side of the parts.

[0007] In some embodiments, the positioning device further includes a loading table, the loading table has a loading surface for loading parts, and the relative movement direction of the positioning member is parallel to the loading surface and perpendicular to the contact surface.

[0008] In some embodiments, there are two or more sets of the positioning assemblies.

[0009] In some embodiments, the relative movement directions of the positioning members in at least two sets of the positioning assemblies intersect.

[0010] In some embodiments, the relative movement directions of the positioning members in at least two sets of the positioning assemblies are perpendicular to each other.

[0011] In some embodiments, the positioning device further includes a driving member, one of the positioning members in the positioning assembly is driven by the driving member to move, and the position of the other positioning member is fixed.

[0012] In some embodiments, when there are two or more sets of the positioning assemblies, the driving member simultaneously drives the positioning members in all the positioning assemblies to move relatively;

[0013] Or

[0014] The driving member independently drives the positioning members in each group of the positioning assemblies to move relatively.

[0015] In some embodiments, a pressure sensor is provided on the contact surface, and the pressure sensor is electrically connected to the driving member.

[0016] In some embodiments, a moving space for the positioning member to move is provided on the loading table.

[0017] The present utility model also provides a feeding device for anodized parts, including the positioning device for anodized parts as described above.

[0018] Applying the above technical solution of the present utility model to a positioning device for anodized parts has the following effects: The positioning assembly is provided, and the parts are positioned by the relative movement of the two positioning members in the positioning assembly. The positioning members in the positioning assembly abut against the inner side of the parts, eliminating abrasions such as scratches on the outer surface of the parts caused by positioning, and ensuring the aesthetics of the parts.

[0019] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation section. Brief Description of the Drawings

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, 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 only used to explain the present utility model and are not used to limit the present utility model.

[0028] Combined with the attached Figure 1 and the attached Figure 2 and the attached Figure 3 , the present utility model discloses a positioning device 1 for anodic oxidation parts, including a loading table 11 and a positioning component 13. The loading table 11 has a loading surface 12 for loading parts. The positioning component 13 positions the parts on the loading surface 12 and is used to position the parts on the loading surface 12 to a specific position. The robotic arm can grasp the parts from the specific position on the loading surface 12, so as to ensure that the positions of the parts grasped and installed on the fixture by the robotic arm are consistent.

[0029] For the positioning component 13, it includes two positioning members 14 that move relative to each other. The end faces of the positioning members 14 that are away from each other along the relative movement direction are contact surfaces 15 for abutting against the inner side of the part. Since the end faces of the two positioning members 14 that are away from each other along the relative movement direction are used to abut against the inner side of the part, during the movement of the positioning members 14, the positioning members 14 only contact the inner side of the part, thus avoiding scratches and wear on the outer surface of the part and ensuring the appearance beauty of the part after positioning.

[0030] In a further setting, the relative movement direction of the positioning members 14 is parallel to the loading surface 12 and both are perpendicular to the contact surface 15. Generally, the loading surface 12 of the loading platform 11 needs to have a certain smoothness and flatness to ensure the movement flexibility of the part on the loading surface 12. And the smooth loading surface 12 can reduce the friction wear and friction noise between the part and the loading platform 11.

[0031] In addition, during the movement and positioning of the part, the inner side of the part needs to abut against the positioning members 14 and the part moves and positions under the pushing action of the positioning members 14. Since the relative movement direction of the positioning members 14 is parallel to the loading surface 12 and both are perpendicular to the contact surface 15, the pushing force direction of the positioning members 14 on the part is parallel to the relative movement direction of the positioning members 14 and the loading surface 12.

[0032] If the force of the positioning members 14 on the part has a component force in the direction perpendicular to the loading surface 12, it will increase the friction force when the part slides on the loading surface 12, affecting the positioning effect and increasing the wear of the part.

[0033] Two or more sets of positioning components 13 are provided to ensure the positioning effect of the part. When the number of the positioning components 13 is two or more, the relative movement directions of the positioning members 14 in at least two sets of the positioning components 13 intersect. It should be noted that generally the loading surface 12 is horizontally arranged. When the part is placed on the loading platform 11, the loading platform 11 restricts the degree of freedom of the part vertically downward, while the degree of freedom of the part vertically upward does not need to be restricted. The positioning components 13 then restrict the degree of freedom and position the part in the horizontal direction. When two sets of positioning components 13 are provided, the positioning directions of the two sets of positioning components 13 for the part are different, that is, the horizontal position of the part can be restricted in terms of degree of freedom and positioned. When three or more sets of positioning components 13 are provided, over-positioning can be performed on the part in the horizontal direction. When the positioning accuracy of one set or more sets of the positioning components 13 deviates, the positioning accuracy of the part can still be ensured, improving the positioning error tolerance rate.

[0034] In a further preferred embodiment, when the number of the positioning components 13 is more than two groups, the relative movement directions of the positioning members 14 in at least two groups of the positioning components 13 are perpendicular to each other, so as to eliminate the mutual interference of different groups of positioning components 13 on the positioning of the parts. The specific description is as follows: When the relative movement directions of the positioning members 14 in two groups of the positioning components 13 form an acute angle, the relative movement direction of the positioning member 14 in one group of the positioning components 13 has a component in the relative movement direction of the positioning member 14 in the other group of the positioning components 13, so that the two groups of positioning components 13 will affect each other when positioning the parts. When the relative movement directions of the positioning members 14 in the two groups of the positioning components 13 are perpendicular to each other, the mutual influence can be eliminated.

[0035] Of course, the number of the positioning components 13 is proportional to the device cost, and the number of the positioning components 13 can be set according to the actual application requirements. In the subsequent description of this application, two groups of the positioning components 13 will be introduced in detail.

[0036] In a further setting, the positioning device 1 further includes a driving member 16. One of the positioning members 14 in the positioning component 13 is driven by the driving member 16 to move, and the position of the other positioning member 14 is fixed. The driving member 16 can adopt a linear cylinder, a linear motor, etc., which can not only improve the automation degree of the device and be applicable to industrial production, but also ensure the moving distance accuracy of the positioning member 14, so as to ensure the positioning accuracy of the parts.

[0037] In a further setting, a moving space 18 for the movement of the positioning member 14 is provided on the loading table 11. The setting of the moving space 18 plays a limiting role and can improve the stability of the positioning member 14 during the sliding process.

[0038] In a further setting, a pressure sensor 17 is provided on the contact surface 15, and the pressure sensor 17 is electrically connected to the driving member 16. The positioning member 14 abuts against the part through the contact surface 15 and pushes the part to move, and the pressure sensor 17 is used to monitor the pressure between the positioning member 14 and the part, and perform real-time monitoring and feedback on the pressure between the positioning member 14 and the part. Specifically, when the pressure between the positioning member 14 and the part is too large, the driving member 16 receives the pressure information fed back by the pressure sensor 17 and stops driving the positioning member 14, so as to avoid obvious deformation of the part due to excessive pressure.

[0039] Specifically, the following embodiments are provided in this application.

[0040] There are two groups of the positioning components 13, and the relative movement directions of the positioning members 14 in the two groups of the positioning components 13 are perpendicular to each other. One of the positioning members 14 in the positioning component 13 is fixedly connected to the loading table 11, and the other positioning member 14 is connected to the driving member 16 and is slidably matched with the loading table 11.

[0041] For the convenience of description, in this embodiment, the two groups of positioning components 13 are respectively referred to as the first positioning component 13a and the second positioning component 13b. The first positioning component 13a includes a first positioning member 14a and a second positioning member 14b, and the first positioning member 14a and the second positioning member 14b move relative to each other along the X direction. The second positioning component 13b includes a third positioning member 14c and a fourth positioning member 14d, and the third positioning member 14c and the fourth positioning member 14d move relative to each other along the Y direction. In this embodiment, the X direction and the Y direction are perpendicular to each other and both are in the horizontal plane. The first positioning member 14a and the third positioning member 14c are slidably engaged with the loading table 11, while the second positioning member 14b and the fourth positioning member 14d are fixedly connected to the loading table 11.

[0042] The moving space 18 is divided into a first moving space 18a and a second moving space 18b. The first moving space 18a is for the first positioning member 14a to slide, and the second moving space 18b is for the third positioning member 14c to slide.

[0043] The positioning member 14 is fixedly connected to the cylinder through a connecting rod 10. The moving space 18 not only serves as a guiding space for the movement of the positioning member 14 but also can be used as a space to accommodate the connecting rod 10. Since the positioning member 14 needs to abut against the inner side of the part, to avoid contact between the connecting rod 10 and the part, the connecting rod 10 is accommodated in the moving space 18.

[0044] In this embodiment, the driving member 16 includes a first driving member 16a for driving the first positioning member 14a to move and a second driving member 16b for driving the third positioning member 14c to move. Specifically, both the first driving member 16a and the second driving member 16b adopt linear cylinders. The first positioning member 14a and the third positioning member 14c are respectively driven independently by the first driving member 16a and the second driving member 16b. Through the start-stop cooperation of the first driving member 16a and the second driving member 16b, multiple positioning modes can be realized, such as first positioning the part along the X direction and then along the Y direction, first positioning along the Y direction and then along the X direction, or positioning along the X and Y directions simultaneously, meeting different application requirements.

[0045] In other embodiments, a single driving member 16 can be used to drive the first positioning member 14a and the third positioning member 14c to move simultaneously, reducing the number of driving members 16 and ensuring the positioning efficiency and the positioning synchronism in the X and Y directions.

[0046] In summary, when there are two or more groups of positioning components 13, a single driving member 16 can be used to drive the positioning members 14 in all positioning components 13 to move relative to each other simultaneously. Or multiple driving members 16 can be used to independently drive the positioning members 14 in each group of positioning components 13 to move relative to each other. It should be noted that the positioning members 14 in the positioning components 13 driven by the driving member 16 mentioned here refer to the movable positioning members 14 in the positioning components 13.

[0047] Combined with the attached Figure 4 , the implementation principle of this embodiment is as follows: The shell-shaped part is placed upside down on the loading table 11, and the positioning member 14 is located inside the part. At this time, neither the positioning member 14 nor the inner side of the part is in contact. Initially, the distance between the first positioning member 14a and the second positioning member 14b is the smallest, and the distance between the third positioning member 14c and the fourth positioning member 14d is the smallest.

[0048] Drive the first positioning member 14a to move along the X direction and away from the second positioning member 14b through the first driving member 16a. The first positioning member 14a abuts against the inner side of the shell and pushes the part to move along the X direction until the inner side of the part abuts against the second positioning member 14b, completing the positioning of the part in the X direction;

[0049] Drive the third positioning member 14c to move along the Y direction and away from the fourth positioning member 14d through the second driving member 16b. The third positioning member 14c abuts against the inner side of the shell and pushes the part to move along the Y direction until the inner side of the part abuts against the fourth positioning member 14d, completing the positioning of the part in the Y direction.

[0050] As shown in the attached Figure 5 , this application also provides a feeding device for anodized parts, including the positioning device 1 for anodized parts as described above. Through the feeding device, automatic feeding can be achieved onto the loading table 11.

[0051] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
