Description

Technical Field

[0001] This utility model relates to the field of aging board technology, specifically an adjustable aging board capacitor tray positioning fixture. Background Technology

[0002] Before capacitor aging tests, a large number of capacitors need to be accurately installed onto the corresponding positions on the aging board, i.e., tray mounting, ensuring precise alignment of capacitor leads with pads to avoid cold solder joints or short circuits. Current tray mounting processes typically rely on manual visual positioning or the use of fixed-specification positioning fixtures, which has the following drawbacks:

[0003] First, manual positioning is inefficient, especially for small surface-mount capacitors, where visual fatigue can easily lead to positioning errors. Second, fixed fixtures are only compatible with a single type of capacitor and aging board; when the layout of the aging board workstation changes, the entire fixture needs to be replaced, increasing production costs. Therefore, it is necessary to design an adjustable positioning fixture to adapt to the tray loading requirements of aging boards with different layouts, improving positioning accuracy and versatility. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable aging board capacitor tray positioning fixture to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An adjustable aging board capacitor tray positioning fixture includes a base, a positioning frame on the top surface of the base, sliding grooves on both sides of the positioning frame, a plurality of connecting frames sliding inside the positioning frame, and sliding rods installed at both ends of each connecting frame. The sliding rods slide within the sliding grooves, and pressure blocks are engaged with the outer sides of the sliding rods, pressing against the sides of the positioning frames. A limit groove is formed on one inner wall of each connecting frame, and a magnet is embedded in the other inner wall of each connecting frame. A plurality of positioning blocks slide within the connecting frames, and a limit groove is installed on one side of each positioning block. The positioning strip slides within the positioning groove, and an iron sheet is embedded on the other side of the positioning block. The magnet attracts the iron sheet, and the top surface of the positioning block has a through hole. The sliding of the connecting frame adjusts the row spacing, and the sliding of the positioning block adjusts the column spacing. This design is adaptable to the workstation layout of aging boards of different specifications, solving the problem of poor universality of the fixing fixture. At the same time, the cooperation between the positioning strip and the positioning groove limits the offset of the positioning block, and the attraction between the magnet and the iron sheet ensures that the positioning block is not easily loosened after fine adjustment. The through hole guides the capacitor to be accurately aligned, and the connecting frame can be fixed by tightening the pressure block.

[0007] Furthermore, the free end of the slide rod extends out of the slide groove, and the part extending out of the slide groove is threaded. The pressure block is a nut, and the pressure block is connected to the slide rod by thread engagement. The threaded connection has self-locking properties, and the pressure block is not easily loosened by vibration after being tightened.

[0008] Furthermore, the bottom surfaces of the positioning frame, the connecting frame, and the pressure block are all flush, providing a stable reference surface for capacitor positioning and further improving positioning accuracy.

[0009] Furthermore, four sets of positioning rods are installed on the top surface of the base, and the positioning frame has four sets of positioning holes. The positioning holes slide within the positioning rods. The cooperation between the positioning rods and the positioning holes makes the position of the positioning frame on the base controllable, avoiding errors in the subsequent capacitor positioning reference due to the offset of the positioning frame.

[0010] Furthermore, the cross-section of the limiting groove is a T-shaped structure, and the cross-section of the limiting strip is adapted to the limiting groove. The anti-detachment design of the T-shaped structure makes the connection between the positioning block and the connecting frame more reliable, preventing the positioning block from falling off during adjustment or tray loading.

[0011] Furthermore, the side of the connecting frame is provided with scale lines, and the minimum division value of the scale lines is 1mm. The side of the positioning block is provided with indicator lines aligned with the scale lines. The cooperation between the scale lines and the indicator lines allows the spacing adjustment of the positioning blocks to be accurate to 1mm, meeting the requirements of high-precision tray loading and solving the problem of size deviation caused by manual visual estimation.

[0012] Furthermore, the bottom surface of the base is provided with four sets of anti-slip feet. The anti-slip feet effectively prevent the tooling from moving during capacitor placement, pressing and other operations, and avoid capacitor positioning deviation caused by tooling displacement.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable aging board capacitor mounting and positioning fixture, through the sliding adjustment of the connecting frame along the positioning frame groove and the sliding adjustment of the positioning block within the connecting frame, combined with the scale line quantization reference, T-type limit, magnetic adsorption and other structures, achieves precise adaptation to the station layout of different models of aging boards. It can ensure that the alignment deviation between the capacitor pins and the pads is controlled within the requirements, and there is no need to customize special fixtures for each type of aging board, thereby improving the mounting efficiency and quality and reducing production costs.

[0022] 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.

[0023] Please see Figure 1 - Figure 7This utility model provides a technical solution: an adjustable aging board capacitor tray positioning fixture, including a base 1, a positioning frame 3 on the top surface of the base 1, sliding grooves 4 on both sides of the positioning frame 3, a plurality of connecting frames 5 sliding inside the positioning frame 3, sliding rods 6 installed at both ends of the connecting frames 5, the sliding rods 6 sliding in the sliding grooves 4, a pressure block 7 engaging with the outer side of the sliding rods 6, the pressure block 7 pressing the side of the positioning frame 3, a limit groove 11 is formed on one side of the inner wall of the connecting frame 5, a magnet 14 is embedded in the other side of the inner wall of the connecting frame 5, a plurality of positioning blocks 8 sliding inside the connecting frame 5, a limit strip 13 is installed on one side of the positioning block 8, the limit strip 13 sliding in the limit groove 11, an iron sheet 12 is embedded in the other side of the positioning block 8, the magnet 14 attracts the iron sheet 12, and the positioning block 8... The top surface of the connecting frame 5 has a through hole 10, which is connected by a threaded connection with the sliding rod 6. The connecting frame 5 slides in the sliding groove 4 of the positioning frame 3 through the sliding rods 6 at both ends, so as to adjust the position of the connecting frame 5 in the positioning frame 3 to adapt to the workstation layout with different row spacing on the aging board. After the adjustment is in place, tighten the pressure block 7 to press the side of the positioning frame 3 and fix the position of the connecting frame 5 by friction. The positioning block 8 slides in the connecting frame 5, and the limiting strip 13 on one side moves along the limiting groove 11 of the connecting frame 5 to ensure the stability of the sliding direction of the positioning block 8. The iron plate 12 on the other side is attracted to the magnet 14 on the inner wall of the connecting frame 5 to fix the position of the positioning block 8 for easy fine adjustment. The through hole 10 on the top surface of the positioning block 8 is used to accommodate the capacitor to be installed, so that the capacitor pins can be accurately aligned with the solder pads on the aging board.

[0024] As an embodiment of this utility model, the free end of the slide rod 6 extends out of the slide groove 4, and the part extending out of the slide groove 4 is threaded. The pressure block 7 is a nut. The part of the slide rod 6 extending out of the slide groove 4 is threaded, and the pressure block 7 engages with the slide rod 6 through the thread. After the position of the connecting frame 5 is adjusted to the correct position, the pressure block 7 is rotated clockwise to move it closer to the side of the positioning frame 3 and press it tightly. The friction between the pressure block 7 and the positioning frame 3 is used to fix the slide rod 6, thereby locking the position of the connecting frame 5. Rotating the pressure block 7 counterclockwise can loosen the fixation and facilitate readjustment of the position of the connecting frame 5.

[0025] As an embodiment of this utility model, the bottom surfaces of the positioning frame 3, the connecting frame 5, and the pressure block 7 are all flush, and are on the same horizontal plane. When the aging board is placed on the base 1, the top surface of the aging board can simultaneously contact the top surface of the positioning frame 3, the bottom surface of the connecting frame 5, and the bottom surface of the pressure block 7, ensuring that the aging board is subjected to uniform force and is in a horizontal state, thus avoiding the impact of local height differences on the capacitor positioning accuracy.

[0026] As an embodiment of this utility model, the top surface of the base 1 is further provided with four sets of positioning rods 2, and the positioning frame 3 has four sets of positioning holes 9. The positioning holes 9 slide in the positioning rods 2. The cooperation between the positioning rods 2 and the positioning holes 9 restricts the horizontal displacement of the positioning frame 3, ensuring that the positioning frame 3 can only move along the vertical direction or a preset trajectory, thus providing a stable installation reference for the connecting frame 5 and the positioning block 8.

[0027] As an embodiment of this utility model, the cross-section of the limiting groove 11 is T-shaped, and the cross-section of the limiting strip 13 is adapted to the limiting groove 11. The T-shaped limiting groove 11 and the adapted limiting strip 13 cooperate, and the limiting strip 13 can slide along the limiting groove 11. At the same time, the T-shaped structure can prevent the limiting strip 13 from disengaging from the limiting groove 11, ensuring that the positioning block 8 always remains connected to the connecting frame 5 and will not fall off or shift during the sliding process.

[0028] As an embodiment of this utility model, the connecting frame 5 is further provided with scale lines on its side, and the minimum division value of the scale lines is 1mm. The positioning block 8 is provided with indicator lines aligned with the scale lines on its side. The scale lines on the side of the connecting frame 5 provide a quantitative reference for the position adjustment of the positioning block 8. The indicator lines on the side of the positioning block 8 are aligned with the scale lines. The operator can accurately control the spacing of the positioning block 8 by reading the scale values, providing data support for the subsequent adjustment of the position of the positioning block 8.

[0029] As an embodiment of this utility model, the bottom surface of the base 1 is provided with four sets of anti-slip feet. The four sets of anti-slip feet on the bottom surface of the base 1 are made of rubber or other high friction coefficient materials, which can generate a large friction force when in contact with the workbench surface, preventing the base 1 from sliding or shifting during the loading operation, and ensuring the stability of the entire fixture.

[0030] On the other hand, this device is designed with multiple models based on the size, number of workstations, and layout differences of different specifications of aging boards. The overall dimensions of the base 1 and positioning frame 3 are different for different models. For example, for models with small aging boards, the length and width of the base 1 are smaller; while for models adapted to large aging boards, the dimensions of the base 1 and positioning frame 3 are increased accordingly to ensure that the aging board can be completely placed on the base 1 and that the positioning frame 3 can completely cover the capacitor mounting area of ​​the aging board. For models adapted to aging boards with fewer workstation rows, fewer connection frames 5 are configured. For aging boards with multiple rows and columns, models with more connection frames 5 are used. By increasing the number of connection frames 5, all rows of workstations are covered, meeting the requirements for multiple rows of capacitors to be mounted. Similarly, the number of positioning blocks 8 in each model matches the number of connection frames 5 and the number of columns of aging boards, that is, the number of positioning blocks 8 and connection frames 5 is greater than the required number.

[0031] Specifically, place base 1 on the workbench, using its four anti-slip feet to ensure stability and prevent slippage. Place the aging board (to be used for capacitor mounting) smoothly on the top surface of base 1, ensuring it is level. Pick up positioning frame 3, aligning its four positioning holes 9 with the four positioning rods 2 on the top surface of base 1, and slide positioning frame 3 downwards, pressing it against the aging board to fix it in place. Based on the row spacing of the solder pads on the aging board, slide connecting frame 5. The sliding rods 6 at both ends of connecting frame 5 will slide synchronously within the sliding grooves 4 on both sides of positioning frame 3. Once connecting frame 5 is in the correct position, tighten the clamping blocks 7 on the outer sides of the sliding rods 6, pressing the sides of positioning frame 3 to fix its position. Based on the column spacing of the solder pads on the aging board, within connecting frame 5... The sliding positioning block 8 has a limiting strip 13 on one side that slides within the limiting groove 11 on the inner wall of the connecting frame 5, ensuring the accuracy of the sliding direction of the positioning block 8. At the same time, observe the scale lines on the side of the connecting frame 5 and the indicator lines on the side of the positioning block 8 to ensure that the positioning block 8 is accurately moved to a position aligned with the solder pads on the aging board. Then, the iron plate 12 embedded on the other side of the positioning block 8 will be attracted by the magnet 14 embedded on the inner wall of the other side of the connecting frame 5, temporarily fixing the position of the positioning block 8. With the capacitor leads facing down, align them with the through hole 10 on the top surface of the positioning block 8 and place the capacitor into the through hole 10, so that the capacitor leads pass through the through hole 10 and are aligned with the solder pads on the aging board. After confirming that all capacitors have been accurately placed, slide the positioning frame 3 upward along the positioning rod 2 and remove it. Finally, perform the soldering operation on the capacitor to complete the process of mounting the capacitor on the aging board.

[0032] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
