Description

Technical Field

[0001] This utility model relates to the field of error-proof fixtures, and in particular to an error-proof fixture for magnetic products. Background Technology

[0002] The magnetic products involved in this application are widely used in the manufacturing of core components for 3C electronic products such as mobile phones, computers, and tablets. These magnetic products require magnetization through a magnetization process, followed by multiple subsequent processing steps before they can be manufactured into precision parts suitable for 3C electronic products.

[0003] In subsequent processes, the magnetized magnetic products must first be placed into a fixture for positioning. However, due to the small size of these magnetic products, it is difficult for humans to accurately identify their magnetic pole orientation (N pole / S pole), i.e., the orientation of the magnetic product. This often leads to the problem of the magnetic pole orientation being reversed during operation, which seriously affects subsequent processes.

[0004] In addition, the existing methods of fixing fixtures and platforms mostly rely on fasteners such as bolts and clips, which require each fixture to be aligned and tightened or snapped together during assembly, which takes a long time and reduces the production efficiency of the production line.

[0005] Therefore, this application proposes a magnetic product error-proof fixture to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a magnetic product error-proof fixture, in which the fixture plate and the platform can be quickly connected or separated, and the magnetic sheet attracts the correctly placed magnetic products on the fixture plate and repels the incorrectly placed magnetic products. The operator can place the magnetic products correctly without thinking or judging.

[0007] To achieve the above objectives, the solution of this utility model is: a magnetic product error-proof fixture, comprising a stage, a fixture plate, and a magnetic sheet; The platform is used to place the fixture plate, which is connected to the platform via a mortise and tenon joint. The bottom surface of the fixture plate has a magnetic sheet, and the top surface of the fixture plate, corresponding to the area of ​​the magnetic sheet, has several contour mounting slots. These slots are used to place magnetic products. When a magnetic product is placed in a contour mounting slot, the magnetic sheet attracts the side of the magnetic product with a polarity different from its own. When the magnetic product is correctly oriented, the polarity of the contact surface between the magnetic product and the contour mounting slot is different from the polarity of the top surface of the magnetic sheet, thus the magnetic sheet attracts the correctly positioned magnetic product.

[0008] Furthermore, the top surface area of ​​the magnetic sheet is smaller than the bottom surface area of ​​the jig plate. The bottom surface of the jig plate is provided with a dovetail groove, and the top surface of the platform is provided with a dovetail tenon. The dovetail groove of the jig plate slides along the dovetail tenon of the platform, and the jig plate is slidably connected to the platform.

[0009] Furthermore, a boss is provided at one end of the top surface of the platform, which is used to limit the fixture plate.

[0010] Furthermore, the boss is provided with a mortise corresponding to the magnetic piece, and the magnetic piece is inserted into the mortise of the boss.

[0011] Furthermore, it also includes a through groove that runs horizontally through the contact surface between the fixture plate and the platform. The magnetic sheet passes through the through groove in a direction parallel to the fixture plate and is placed between the platform and the fixture plate. The top surface of the magnetic sheet is flush with the bottom surface of the fixture plate.

[0012] Furthermore, a handle is provided at one end of the magnetic sheet along the insertion slot direction, making it convenient for the operator to hold the magnetic sheet and insert it into the slot.

[0013] Furthermore, the fixture plate is provided with a tenon, and the platform is provided with a corresponding mortise, and the tenon of the fixture plate is inserted into the mortise of the platform.

[0014] Furthermore, the fixture plate is provided with recessed handholds on both opposite sides, which facilitates the operator or robot arm to install the fixture plate onto the platform.

[0015] Furthermore, several contoured mounting slots are arranged in a rectangular array on the fixture plate.

[0016] Furthermore, a connecting groove is provided between the longitudinally aligned contour mounting grooves, or between the transversely aligned contour mounting grooves.

[0017] The advantages of this solution are as follows: the fixture plate and the platform are connected or separated quickly using a mortise and tenon structure; the magnetic sheet can identify the placement status of magnetic products—it generates an attractive magnetic force for magnetic products that are correctly placed on the fixture plate, and a repulsive magnetic force for those that are incorrectly placed. Through this "attractive-repulsive" mechanism, the operator can complete the correct placement of magnetic products without additional judgment. Attached Figure Description

[0020] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are illustrative of this application but are not intended to limit the scope of this application.

[0021] It should be understood that the orientation indicated by terms such as "top surface," "bottom surface," "longitudinal," and "lateral" in this application is based on the orientation shown in the accompanying drawings and is only for the purpose of description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] A foolproof fixture for magnetic products 5 includes a platform 1, a fixture plate 2, and a magnetic sheet 3. The platform 1 is used to place the fixture plate 2, and the fixture plate 2 is connected to the platform 1 by a mortise and tenon structure. The bottom surface of the fixture plate 2 is provided with the magnetic sheet 3, and the top surface of the fixture plate 2, corresponding to the area of ​​the magnetic sheet 3, is provided with several contour mounting grooves 21. The contour mounting grooves 21 are used to place the magnetic products 5. When the magnetic product 5 is placed in the contour mounting groove in the correct direction, the bottom of the magnetic product 5 is close to the top of the magnetic sheet 3. Since the polarities of the two are different, like repels like and unlike attracts, so the magnetic sheet 3 attracts the correctly placed magnetic product 5. Conversely, if the magnetic product 5 is placed in the contour mounting groove in the wrong direction, the top of the magnetic product 5 is close to the top of the magnetic sheet 3. Since the polarities of the two are the same, the magnetic product 5 is ejected from the contour mounting groove under the action of repulsion. The operator can screen out the incorrectly placed magnetic product 5 without judgment or thought. It should be noted that magnetic field lines have a certain penetrating power, so the magnetic field lines of the magnetic sheet 3 can penetrate the bottom of the contour mounting groove 21 and act on the magnetic product 5.

[0023] like Figure 1 and Figure 2 In one embodiment shown, the top surface area of ​​the magnetic sheet 3 is smaller than the bottom surface area of ​​the jig plate 2. The two opposite sides of the bottom surface of the jig plate 2 protrude to form dovetail grooves 12, and the two opposite sides of the top surface of the platform 1 are recessed to form dovetail tenons 22. During installation, one end of the dovetail groove 12 of the jig plate 2 is first engaged with one end of the dovetail tenon 22 of the platform 1. Then, the dovetail groove 12 of the jig plate 2 slides along the dovetail tenon 22 of the platform 1, and the jig plate 2 is slidably connected to the platform 1. When disassembling and replacing the jig plate 2, it can be slid out in the opposite direction. The jig plate 2 can be quickly disassembled and installed, and the operation is convenient.

[0024] One end of the top surface of the platform 1 is provided with a boss 15, which is used to limit the fixture plate 2.

[0025] The magnetic sheet 3, positioned between the platform 1 and the fixture plate 2, already serves a fixing function. Further optimization involves providing a mortise 13 on the boss 15 of the platform 1, corresponding to the magnetic sheet 3. The cross-sectional dimensions of the mortise 13 are the same as those of the magnetic sheet 3, ensuring a tight fit between the magnetic sheet 3 and the mortise 13. Figure 1 The magnetic piece 3 shown is inserted horizontally into the mortise 13, which provides a better fixing effect.

[0026] like Figure 3 and Figure 4 In one embodiment shown, a through groove 4 is further provided that extends laterally through the contact surface between the fixture plate 2 and the platform 1. The magnetic sheet 3 passes through the through groove 4 in a direction parallel to the fixture plate 2 and is placed between the platform 1 and the fixture plate 2. The top surface of the magnetic sheet 3 is flush with the bottom surface of the fixture plate 2. The cross-sectional dimensions of the through groove 4 are the same as those of the magnetic sheet 3, ensuring that the magnetic sheet 3 and the through groove 4 fit together tightly.

[0027] The magnetic plate 3 has a handle 31 at one end along the insertion slot 4, which makes it easy for the operator to hold the magnetic plate 3 and insert it into the slot 4. This insertion design also enhances the versatility of the fixture. For example, when a magnetic product 5 with a different polarity is placed on the fixture plate 2, even if the other magnetic product 5 is placed correctly, the magnetic plate 3 will still repel the other magnetic product 5. At this time, the operator can remove the magnetic plate 3 and replace it with another magnetic plate 3 that matches the other magnetic product 5. Then the fixture can still prevent the magnetic product 5 from being placed incorrectly.

[0028] like Figure 3 As shown, the jig plate 2 is provided with a tenon 24, and the platform 1 is provided with a corresponding mortise 14. The tenon 24 of the jig plate 2 is inserted into the mortise 13 of the platform 1. This tenon-mortise connection facilitates the quick assembly and disassembly of the jig plate 2 onto the platform 1, and effectively enhances the fixation between the two.

[0029] The fixture plate 2 is provided with recessed handholds 31 on both opposite sides. When the operator and the robot arm disassemble or assemble the fixture plate 2, they hold the opposite recessed handholds 31 to disassemble or assemble the fixture plate 2 onto the platform 1.

[0030] Several contour mounting slots 21 are arranged in a rectangular array on the fixture plate 2. A connecting slot 4 is provided between the longitudinally aligned contour mounting slots 21, or between the transversely aligned contour mounting slots 21. The design of the connecting slot 4 is mainly to reserve space for the robot arm to grip the magnetic product 5 in subsequent processes, so as to avoid interference between the robot arm and the fixture plate 2 structure.

[0031] The basic principles, main features and advantages of this utility model have been described above. It is obvious to those skilled in the art that this utility model is not limited to the details of the preferred embodiments described above. The embodiments should be regarded as exemplary and non-limiting. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims within this utility model.
