Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, specifically to a positioning fixture for communication electronic components. Background Technology

[0002] In the field of communication equipment manufacturing, the appearance quality inspection of circular electronic components is a key link to ensure product reliability. Among them, safety-certified Y capacitors, magnetic rod inductors, and toroidal inductors require comprehensive testing through precise positioning due to their structural characteristics.

[0003] Traditional techniques for positioning circular components typically employ fixed-size fixtures, where a pre-fabricated circular groove matching the component's outer diameter is placed on the testing stage, and positioning is achieved through fitting. This method relies on the dimensional matching between the component and the groove, is simple to operate, and has low cost, meeting basic requirements for single-specification mass production. However, the diverse applications of communication equipment necessitate adapting the same type of component to different power, frequency, and other parameters, resulting in various diameter specifications (e.g., the diameter of a magnetic rod inductor often ranges from 3mm to 25mm). When production batches change or specifications are adjusted, existing fixed-groove fixtures cannot accommodate components of different sizes, requiring the redesign and fabrication of dedicated fixtures. This not only increases fixture manufacturing costs and inventory pressure but also extends production preparation time due to frequent fixture changes, reducing the flexibility and efficiency of the testing process. Therefore, we propose a positioning fixture for communication electronic components to address these issues. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This application provides a positioning fixture for communication electronic components, mainly to solve the problem that existing fixed circular groove fixtures are incompatible with components of different sizes when production batches change or specifications are adjusted, requiring the redesign and fabrication of dedicated fixtures. This not only increases the manufacturing cost and inventory pressure of the fixture, but also prolongs production preparation time due to frequent fixture changes, reducing the flexibility and efficiency of the inspection process. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0024] A positioning fixture for communication electronic components, comprising:

[0025] A rectangular base 1 has a mounting groove 101 on one side. The mounting groove 101 is a right trapezoid with an inclined bottom surface. A tapered hole 102 is equally spaced in the middle of the top of the rectangular base 1. The tapered hole 102 is connected to the mounting groove 101. A rectangular channel 103 is inclined upward on the bottom side of the front of the rectangular base 1. The rectangular channel 103 is connected to the mounting groove 101.

[0026] Mounting block 2 is in the shape of a right trapezoid and is slidably embedded in the interior of mounting groove 101. A tapered groove 201 is provided on the top of mounting block 2 corresponding to the position of tapered hole 102, and the top of tapered groove 201 is connected to the bottom of tapered hole 102.

[0027] The detection component 3 is set on the top of the rectangular base 1. The detection component 3 is used to detect electronic components. The detection component 3 includes a fixing rod 301 fixed at the four corners of the top surface of the rectangular base 1. A mounting plate 302 is fixed on the top of the fixing rod 301. A strip hole 3021 is constructed in the middle of the mounting plate 302. A T-shaped block 303 is slidably embedded in the inside of the strip hole 3021. An electric push rod 304 is installed on one side of the mounting plate 302. The piston end of the electric push rod 304 is connected to the T-shaped block 303. A CCD appearance inspection instrument 305 is installed in the middle of the bottom of the T-shaped block 303.

[0028] Workflow Description

[0029] Preparation stage: The mounting block 2 is precisely and smoothly slid into the mounting groove 101 along the inclined bottom surface of the mounting groove 101. At this time, the conical groove 201 at the top of the mounting block 2 is accurately aligned with the conical hole 102 at the top of the rectangular seat 1, together forming a complete conical receiving cavity.

[0030] Material loading and positioning stage: The circular electronic components to be tested are slowly and one by one placed into the conical hole 102. Based on the conical structure characteristics formed by the combination of the conical hole 102 and the conical groove 201, the components will automatically and quickly slide towards the bottom of the cone under the action of gravity until they are stably stopped in the conical groove 201. During this process, the central axis of the component can be precisely aligned with the central axis of the conical cavity, thereby achieving high-precision positioning. This positioning method is not affected by the variation of the component diameter within a certain range. As long as the diameter is within the range that the conical hole 102 and the conical groove 201 can be adapted, it can be effectively positioned.

[0031] Inspection phase: When the inspection component 3 is turned on, the electric push rod 304 is powered on and started. Its piston end extends or retracts smoothly, driving the T-shaped block connected to it to slide horizontally in the strip hole 3021 of the mounting plate 302. The CCD appearance inspection instrument installed at the bottom of the T-shaped block moves accordingly to perform appearance inspection on the electronic components that have been positioned in the conical groove 201.

[0032] Discharge stage: After the inspection is completed, the components are discharged according to their position in the conical groove 201. If the diameter of the component is exactly equal to the diameter of the upper end of the conical groove 201, after the mounting block 2 is pulled out of the mounting groove 101, the component will naturally slide down along the rectangular channel 103 inclined upward on the bottom side of the front of the rectangular base 1 under its own gravity, realizing automatic material discharge; if the component is inserted into the conical hole 102 and the top is submerged in the conical groove 201, the operator can use tweezers or other tools to directly remove the component from above the conical hole 102; if the component is inserted into the conical hole 102 but the top is not submerged in the conical groove 201, the operator can pull the mounting block 2 from the mounting groove 101 smoothly by pulling the pull rod 202 fixed on the side of the mounting block 2 near the end of the rectangular groove. At this time, the component is exposed in the conical groove 201, which is convenient for the operator to remove. At the same time, the receiving groove 5 set on the bottom side of the front of the rectangular base 1 can collect the components that slide down from the rectangular channel 103 in a unified manner, which is convenient for subsequent sorting and circulation.

[0033] This communication electronic component positioning fixture abandons the traditional single-groove design of fixed-specification fixtures, creatively adopting a positioning structure composed of a conical hole 102 and a conical groove 201, which can accommodate circular components of various diameters. This innovative design breaks through the limitations of fixed size, enabling rapid and accurate positioning of circular electronic components of different diameters (such as magnetic rod inductors with diameters ranging from 3mm to 25mm) on the same fixture, greatly improving the versatility and applicability of the fixture, and effectively solving the problem of frequent fixture changes caused by the diversification of component specifications.

[0034] like Figure 3 As shown, in some embodiments, supplementary lights 306 are installed at the four corners of the bottom surface of the T-shaped block 303. More specifically, from the perspective of the installation position, the layout of the four corners of the supplementary lights 306 can form an all-round surround illumination range, which can accurately cover the electronic component inspection area located in the conical groove 201 below. In traditional inspection, if the lighting position is singular or the light distribution is uneven, shadows or dark areas are easily formed on the surface of the component, causing the CCD appearance inspection instrument to be unable to clearly capture subtle defects. However, when the supplementary lights 306 at the four corners work simultaneously, the light can illuminate the surface of the component from different angles, complementing each other to eliminate shadows and providing sufficient and uniform light for the inspection area.

[0035] like Figure 1 As shown, in some embodiments, a limiting member 4 is also included, disposed on the side wall of the rectangular base 1. The limiting member 4 is used to prevent the mounting block 2 from disengaging from the mounting groove 101. The limiting member 4 includes an L-shaped plate 401 fixed to one side of the side wall of the rectangular base 1, and a hinge plate 402 hinged to the other side of the side wall of the rectangular base 1. The hinge plate 402 is slidably embedded in the L-shaped plate 401. More specifically, in use, after the mounting block 2 is embedded in the mounting groove 101, the hinge plate 402 is rotated so that its edge aligns with the groove of the L-shaped plate, and the hinge plate 402 is pushed to slide into the L-shaped plate. At this time, the hinge plate 402 just seals the groove of the mounting groove 101, forming a mechanical block. This design, through a simple mechanical fitting structure, utilizes the hinge plate 402 and the L-shaped plate to achieve this. The fit of the template restricts the sliding trajectory of the mounting block 2, effectively preventing the mounting block 2 from detaching from the mounting groove 101 due to vibration or accidental contact during the testing process, ensuring that the conical hole 102 and the conical groove 201 are always accurately aligned, thus guaranteeing positioning stability and testing reliability.

[0036] like Figure 1As shown, in some embodiments, a pull rod 202 is fixed on one side of the mounting block 2 near the rectangular slot port, and an arc-shaped notch 4021 adapted to the pull rod 202 is constructed on the bottom side of the hinge plate 402. More specifically, when the mounting block 2 is embedded in the mounting slot 101 and limited by the hinge plate 402, the arc-shaped notch 4021 will naturally engage with the outer periphery of the pull rod 202 during the process of rotating the hinge plate 402 to embed it into the L-shaped plate. This fitting design does not affect the closing and limiting of the mounting slot 101 by the hinge plate 402.

[0037] like Figure 1 As shown, in some embodiments, a receiving groove 5 is provided on the bottom side of the front of the rectangular base 1. More specifically, when a component with a diameter equal to the diameter of the upper port of the conical groove 201 is detected, it will slide naturally down along the rectangular channel 103. The receiving groove 5 is located just below the outlet of the rectangular channel 103, which can accurately receive the sliding component and prevent it from falling directly and causing damage or loss.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
