Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic component positioning fixture technology, specifically to an electronic component positioning fixture for offset correction. Background Technology
[0002] Precise positioning of electronic components (such as chips, resistors, capacitors, connectors, etc.) is a core aspect of the electronics manufacturing industry, directly affecting product assembly quality and functional stability. In scenarios such as surface mount technology (SMT), integrated circuit packaging, and precision instrument assembly, if the component positioning deviation exceeds 0.05mm, it may lead to problems such as poor soldering, short circuits, and abnormal signal transmission. Positioning fixtures are indispensable as key equipment for achieving precise positioning. Existing electronic component positioning fixtures typically use mechanical parts to position components from a horizontal position, with positioning accuracy being a key factor.
[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN216913562U, published on 2022-07-08) provides a positioning fixture for electronic component processing and manufacturing. First, based on the length of the electronic component, a first threaded rod is rotated, causing the inner side plate to slide on the base plate, thereby adjusting the distance between the two inner side plates. This ensures that the length of the electronic component to be processed matches the distance between the inner side plates. After adjustment, the electronic component is placed on a fixed plate. By rotating a second threaded rod, a moving plate is moved downwards and comes into contact with the electronic component, thus achieving clamping operation. The sliding adaptation between the second sliding groove and the second slider effectively ensures the stability of the moving plate when sliding on the inner side plate. A circular track is provided below the support frame, facilitating adjustments of the workpiece to be processed in different horizontal directions by the operator.
[0004] The above solution relies solely on mechanical structure to ensure accuracy during use, and cannot cope with random offsets during component placement. For example, if there are deviations during manual loading and placement, the tooling cannot automatically correct them, directly leading to the failure of subsequent processes. Utility Model Content
[0005] The purpose of this invention is to provide an electronic component positioning fixture for offset correction, in order to solve the problem that the existing electronic component positioning fixtures mentioned in the background art rely solely on mechanical structures to ensure accuracy during use, and cannot cope with random offsets during component placement, such as deviations during manual loading and placement, which the fixture cannot automatically correct, directly leading to the failure of subsequent processes.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic component positioning fixture for offset correction, comprising a base plate, a horizontal groove on the top of the base plate, a slider symmetrically slidably connected in the horizontal groove, a positioning plate fixed on the top of the slider, and a pressure plate slidably connected through the top of the positioning plate.
[0007] The positioning plate is symmetrically hinged to the front and rear sides with a correction component, and the correction component contacts the electronic component before the positioning plate.
[0008] The positioning plate has cleaning jet components symmetrically arranged on the front and rear sides of its top. These cleaning jet components spray air while positioning the electronic components, keeping them clean.
[0009] Furthermore, a motor is installed inside the left side of the base plate, and a reverse lead screw is connected to the output end of the motor. A slider is symmetrically threaded onto the reverse lead screw, and the slider drives the positioning plate to form a horizontal positioning structure.
[0010] Furthermore, the correction component includes a correction plate symmetrically hinged to the front and rear sides of the positioning plate, a torsion spring is installed at the connection between the correction plate and the positioning plate, and the correction plate is configured as a concave arc-shaped structure.
[0011] Furthermore, sleeves are symmetrically fixed on the front and rear sides of the positioning plate, and a sliding plate is slidably connected in the sleeve. The outer side of the sliding plate is fixedly connected to the outer side of the correction plate. A first air storage bag is installed inside the sleeve, and the sliding plate is in pressure contact with the first air storage bag.
[0012] Furthermore, the first air reservoir is connected to the interior of the correction plate via a connecting pipe. The interior of the correction plate is a hollow structure, and air jet holes are evenly spaced on the surface of the correction plate.
[0013] Furthermore, the positioning plate is equipped with an electric push rod inside, and a pressure plate is connected to the top of the electric push rod. The pressure plate is configured with a barb-shaped structure, and crossbars are symmetrically fixed on the front and rear sides of the pressure plate. The crossbars are slidably connected to a "Z"-shaped guide groove, which is correspondingly opened on the side of the connecting frame. The connecting frame is symmetrically rotatably connected to the top of the positioning plate.
[0014] Furthermore, the cleaning jet component includes a second air reservoir symmetrically installed inside the positioning plate. The bottom of the pressure plate presses against the second air reservoir. The second air reservoir is connected to the jet pipe through a connecting pipe. The jet pipe is fixedly installed on the top of the connecting frame, and the air outlet of the jet pipe is inclined towards the center line of the base plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This offset correction electronic component positioning fixture, during use, uses the correction plates on the front and rear sides of the positioning plate to push the electronic component to the centerline position before the positioning plate is positioned, thus keeping the electronic component from shifting in the initial state. Then, the horizontal positioning plate and the vertical pressure plate stably clamp and position the electronic component. At the same time as positioning, the surface of the electronic component is cleaned by blowing air to keep it clean and facilitate subsequent processes.
[0017] Furthermore, the motor drives the reverse lead screw to rotate, causing the slider and positioning plate in the transverse groove to move towards each other. The concave arc-shaped structure of the correction plate hinged to the front and rear sides of the positioning plate contacts the electronic component before the positioning plate. When its inner arc surface contacts the edge of the electronic component, it generates an inward thrust under the elastic force of the torsion spring, pushing the offset electronic component towards the center line of the base plate.
[0018] Furthermore, when the correction plate rotates outward under force, it causes the sliding plate inside the sleeve to squeeze the first air storage bag. The gas in the first air storage bag is transported to the internal hollow structure of the correction plate through the connecting pipe and is ejected from the air jet hole on the surface of the correction plate, which initially removes the floating dust on the surface of the component and at the same time avoids the component from being scratched due to friction during correction.
[0019] Furthermore, the positioning plate completes the initial positioning through horizontal clamping force, and the electric push rod drives the pressure plate to move to achieve vertical fixation. When the pressure plate moves down, the crossbar slides along the guide groove, causing the connecting frame to swing back and forth, so that the jet pipe sprays air to clean the electronic components. The pressure plate moves down to squeeze the second air storage bag, and the gas is delivered to the jet pipe through the connecting pipe. The air outlet of the jet pipe is tilted towards the center line of the base plate and aligned with the surface of the electronic components. The sprayed airflow can remove dust or impurities from the surface of the components. The cleaning process is carried out simultaneously with the positioning to avoid component displacement caused by secondary operations after positioning, and to ensure the smooth progress of subsequent processes such as welding and packaging.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solution: an electronic component positioning fixture for offset correction, comprising a base plate 1, a transverse groove 2 on the top of the base plate 1, a slider 5 symmetrically slidably connected in the transverse groove 2, a positioning plate 6 fixed on the top of the slider 5, a pressure plate 13 slidably connected through the top of the positioning plate 6, and a correction component symmetrically hinged to the front and rear sides of the positioning plate 6, wherein the correction component contacts the electronic component before the positioning plate 6, and a cleaning jet component symmetrically arranged on the front and rear sides of the top of the positioning plate 6, wherein the cleaning jet component sprays air while positioning to keep the electronic component clean.
[0029] In use, the device uses the base plate 1 as the supporting foundation. The reverse lead screw 3 drives the slider 5 to move the positioning plate 6 to achieve horizontal clamping and positioning. The correction components on the front and rear sides complete the centerline calibration of the electronic components before positioning, and the pressure plate 13 positions and fixes the electronic components in the vertical direction. The cleaning jet component on the top of the positioning plate 6 blows air to clean the surface of the components during the positioning process. The three are linked by mechanical transmission and air pressure to form an integrated process of "correction-positioning-cleaning", which solves the problem that traditional tooling cannot deal with random offset.
[0030] Example 2: Based on Example 1, a correction and positioning mechanism is also disclosed. Please refer to [link / reference]. Figure 1 - Figure 4As shown, its specific structure is as follows: a motor 4 is installed inside the left side of the base plate 1. The output end of the motor 4 is connected to a reverse lead screw 3. A slider 5 is symmetrically threaded on the reverse lead screw 3. The slider 5 drives the positioning plate 6 to form a horizontal positioning structure. The correction component includes a correction plate 7 symmetrically hinged to the front and rear sides of the positioning plate 6. A torsion spring 8 is installed at the connection between the correction plate 7 and the positioning plate 6. The correction plate 7 is set as an inwardly concave arc-shaped structure.
[0031] During use, the motor 4 drives the reverse lead screw 3 to rotate, causing the slider 5 and the positioning plate 6 in the transverse groove 2 to move towards each other. The concave arc structure of the correction plate 7, which is hinged on the front and rear sides of the positioning plate 6, contacts the electronic component before the positioning plate 6. When its inner arc surface contacts the edge of the electronic component, it generates an inward thrust under the elastic force of the torsion spring 8, pushing the offset electronic component towards the center line of the base plate 1.
[0032] As shown in the figure, sleeves 9 are symmetrically fixed on the front and rear sides of the positioning plate 6. A sliding plate 10 is slidably connected in the sleeve 9. The outer side of the sliding plate 10 is fixedly connected to the outside of the correction plate 7. A first air storage bag 19 is installed inside the sleeve 9. The sliding plate 10 and the first air storage bag 19 are in pressure contact. The first air storage bag 19 is connected to the inside of the correction plate 7 through a connecting pipe. The inside of the correction plate 7 is set as a hollow structure. Air jet holes 11 are opened at equal intervals on the surface of the correction plate 7.
[0033] During use, when the correction plate 7 is rotated outward under force, it causes the slide plate 10 inside the sleeve 9 to squeeze the first air storage bag 19. The gas inside the first air storage bag 19 is transported to the internal hollow structure of the correction plate 7 through the connecting pipe and is ejected from the air jet hole 11 on the surface of the correction plate 7, which initially removes the floating dust on the surface of the component and at the same time avoids the component from being scratched due to friction during correction.
[0034] Example 3: Based on Example 2, a cleaning jet mechanism is also disclosed. Please refer to [link / reference]. Figure 4 - Figure 6 As shown, its specific structure is as follows: An electric push rod 12 is provided inside the positioning plate 6. A pressure plate 13 is connected to the top of the electric push rod 12. The pressure plate 13 is configured with a barb-shaped structure. A crossbar 16 is symmetrically fixed on the front and rear sides of the pressure plate 13. The crossbar 16 is slidably connected to the "Z"-shaped guide groove 17. The guide groove 17 is correspondingly opened on the side of the connecting frame 14. The connecting frame 14 is symmetrically rotated and connected to the top of the positioning plate 6. The cleaning jet component includes a second air bladder 18 symmetrically installed inside the positioning plate 6. The bottom of the pressure plate 13 is pressed against the second air bladder 18. The second air bladder 18 is connected to the jet pipe 15 through a connecting pipe. The jet pipe 15 is fixedly installed on the top of the connecting frame 14. The air outlet of the jet pipe 15 is inclined towards the center line of the bottom plate 1.
[0035] During use, after the correction is completed, the positioning plate 6 and the pressure plate 13 cooperate to achieve rigid fixation of the component. The positioning plate 6 continues to move towards each other until its inner side is in contact with the edge of the component. The initial positioning is completed by the clamping force in the horizontal direction. The electric push rod 12 inside the positioning plate 6 drives the pressure plate 13 to move downward. Its barbed structure presses the component from above to achieve vertical fixation. When the pressure plate 13 moves down, the crossbars 16 on the front and rear sides slide along the "Z"-shaped guide grooves 17 on the side of the connecting frame 14, causing the connecting frame 14 to swing back and forth, so that the jet pipe 15 swings and cleans the electronic component. During the downward movement of the pressure plate 13, the second air storage bag 18 inside the positioning plate 6 is squeezed. The gas in the second air storage bag 18 is transported to the jet pipe 15 at the top of the connecting frame 14 through the connecting pipe. The air outlet of the jet pipe 15 is tilted towards the center line of the base plate 1 and aligned with the surface of the electronic component. The airflow can remove dust or impurities from the surface of the component. The cleaning process is carried out simultaneously with the positioning to avoid component displacement caused by secondary operation after positioning and to ensure the smooth progress of subsequent processes such as welding and packaging.
