Abstract
Description
Technical Field
[0001] The utility model relates to a guide frame compatible with products of multiple sizes, belonging to the technical field of product installation. Background Art
[0002] During the chip production process, chip manufacturers set up guide frames for chip placement to facilitate component assembly, quality testing and final product packaging. Different types of chips require guide frames of matching sizes. Although chip design companies specify the chip size and corresponding tolerance range at the beginning of chip design, there are still great differences in actual production results. This out-of-tolerance design is gradually unified in production, resulting in the inability of the test socket industry to achieve batch compatibility with the chip limit guide frame.
[0003] In the existing guide frame production, the test socket manufacturer produces the guide frame according to the standard size of the chip. This will cause the chip with a large dimensional tolerance to be unable to be placed in the guide frame during testing, causing material jamming. For chips with a small dimensional tolerance, the guide frame size is larger than the chip, and the chip cannot be limited, so that during testing, the probe cannot perfectly contact the chip's PAD point.
[0004] In order to solve the problem that chips of different sizes cannot be effectively installed for testing due to chip tolerance, the solution currently adopted by test socket manufacturers is to design guide frames of various sizes so that the guide frames can be replaced when testing chips of different types and sizes. This solution is a compromise to the current testing industry. At the same time, since chips of different tolerance sizes need to be classified in advance, the work of test socket manufacturers has undoubtedly increased, resulting in increased costs. Therefore, there is an urgent need for a product guide frame to solve the problem that when testing chips, guide frames of various sizes need to be designed for chips of different sizes, resulting in low applicability of guide frame products and high production costs. Utility Model Content
[0005] The purpose of the utility model is to provide a guide frame compatible with products of multiple sizes, so as to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide frame compatible with products of multiple sizes, including a mounting seat and a pressure block, the number of the pressure blocks is at least two, all the pressure blocks are relatively installed on the mounting seat, and form a mounting groove with a shape that matches the shape of the product. At least one of the pressure blocks is slidably installed on the mounting seat to adjust the size of the mounting groove; a locking element is installed on the pressure block slidably installed on the mounting seat, which is used to push the pressure block against the product to lock the product.
[0007] Specifically, the mounting seat is provided with mounting tracks with the same number as the number of the pressing blocks in a direction away from the mounting slot, with the pressing blocks being installed in the mounting tracks one by one. By providing mounting tracks for installing the pressing blocks, the pressing blocks slidably mounted on the mounting seat can slide along the mounting tracks when sliding, and the pressing blocks will not be offset, thereby ensuring that the pressing blocks slide smoothly and stably abut against the product, thereby avoiding damage to the product.
[0008] Specifically, the pressing block slidably mounted on the mounting seat is defined as a movable pressing block; a locking block is installed on the upper mounting seat of the mounting track where the movable pressing block is located; and a movable track for sliding the movable pressing block is formed between the locking block and the mounting track.
[0009] Specifically, the groove walls on both sides of the mounting rail at the position of the movable rail are respectively recessed inward to form a T-shaped rail; the two sides of the end of the movable pressure block on one side of the T-shaped rail are respectively protruded outward to form a T-shaped limiting portion that forms a concave-convex fit with the T-shaped rail; the movable pressure block is slidably installed on the T-shaped rail through the T-shaped limiting portion, and is slidably installed on the mounting seat under the radial limitation of the locking block.
[0010] Specifically, one end of the locking block located at the T-shaped track position extends radially toward the T-shaped track to form an extended end, and the extended end is located within the sliding track of the movable pressing block to limit the sliding stroke of the movable pressing block; a locking element is installed between the extended end and the movable pressing block. By setting the locking block to form a movable track, the pressing block can slide within a certain stroke.
[0011] Specifically, the locking element is an elastic member; the two ends of the elastic member are respectively against the extension end and the movable pressure block. By arranging the elastic member between the locking block and the pressure block, it is achieved that when the chip is installed, the chip pushes the movable pressure block to slide, and the size of the installation slot is adjusted, so that the chip can be installed in the guide frame to adapt to the diversity of chip sizes caused by chip size tolerance problems. At the same time, when the chip is installed, the sliding of the movable pressure block will compress the elastic member to deform and generate elastic potential energy. The reaction force of the elastic potential energy can be used to press and clamp the chip to ensure that the chip remains stably placed during testing and packaging. The elastic member of the present application can be selected from elastic deformation members such as springs and shrapnel in the prior art, and springs are preferred.
[0012] Specifically, a wedge-shaped structure is provided on one side of the mounting groove of the pressing block, and all the pressing blocks are surrounded by the wedge-shaped structure to form a mounting groove with a draft angle. This arrangement ensures that the chip can remain stable during the placement or removal of the chip, and the reaction force of the pressing block on the chip is relatively uniform, without causing wear to the chip.
[0013] Specifically, the end of the wedge-shaped structure of the pressing block is concave radially inward to form an abutting end against the product. This arrangement enables the abutting end of the vertical structure to stably abut against the chip under the action of the elastic member after the chip is placed, thereby maintaining stable clamping during the test process.
[0014] Specifically, the number of the pressing blocks and the number of the mounting rails are both four; the four mounting rails are evenly spaced on the mounting seat, and the four pressing blocks are respectively installed in the mounting rails in a one-to-one correspondence to form a square mounting groove.
[0015] Specifically, the four pressing blocks are slidably installed in the installation rails respectively. In this way, when the chip is placed, the square structure of the chip can simultaneously push the movable pressing blocks to slide and clamp the chip, thereby ensuring the stability of chip placement.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] 1. The present application sets at least two pressing blocks to be installed relative to each other to enclose a mounting groove that matches the shape of the chip, and slides at least one of the pressing blocks on the mounting seat to adjust the size of the mounting groove. This allows the installation of chips of various sizes due to tolerance deviations to be completed with only one guide frame. There is no need to produce guide frames of various sizes for replacement, which reduces production costs and improves the efficiency of chip packaging. In order to ensure that the chip is evenly stressed and stably placed during chip installation, the present application sets four pressing blocks to be slidably installed on the mounting seat, and sets elastic members, so that the four sides of the chip simultaneously push the pressing blocks to slide, and compress the elastic members to deform to generate elastic force to clamp the chip.
[0018] 2. On the basis of the foregoing, the present application sets a wedge-shaped structure and a radial abutment end at the end of the movable pressing block to achieve that when the chip is installed, the chip slides along the wedge-shaped structure of the pressing block, and the pressing block slides as the chip is placed, so that the force is evenly distributed and the wear is small. After the chip is placed, the abutment end of the vertical structure of the pressing block can be tightly attached to the chip under the action of elastic force, so as to clamp and fix the chip, so as to ensure that the chip is stably placed during the test and improve the test quality.

[0025] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.
[0026] See also Figure 1-6 A guide frame compatible with products of multiple sizes includes a mounting seat 1 and a pressing block 2, the number of the pressing blocks 2 is at least two, all the pressing blocks are relatively mounted on the mounting seat, and a mounting groove 3 whose shape is adapted to the shape of the product is enclosed between them, at least one of the pressing blocks is slidably mounted on the mounting seat to adjust the size of the mounting groove; a locking element is installed on the pressing block slidably mounted on the mounting seat, which is used to push the pressing block against the product to lock the product 4.
[0027] The mounting seat of this embodiment is centered on the mounting groove, and a number of mounting tracks equal to the number of pressing blocks is opened in the direction away from the mounting groove, and the pressing blocks are installed in the mounting tracks one by one. Specifically, the number of pressing blocks and mounting tracks of this embodiment is four; the four mounting tracks are evenly spaced on the mounting seat, and the four pressing blocks are installed in the mounting tracks one by one to form a square mounting groove, and the four pressing blocks are slidably installed in the mounting tracks.
[0028] In this embodiment, the pressing block slidably mounted on the mounting seat is defined as a movable pressing block; a locking block 5 is installed on the upper mounting seat of the mounting track where the movable pressing block is located; a movable track for sliding the movable pressing block is formed between the locking block and the mounting track. Among them, the groove walls on both sides of the mounting track where the movable track is located are respectively recessed inward to form a T-shaped track; the two sides of the end of the movable pressing block located on one side of the T-shaped track are respectively convex outward to form a T-shaped limiting portion that forms a concave-convex match with the T-shaped track; the movable pressing block is slidably mounted on the T-shaped track through the T-shaped limiting portion, and is slidably mounted on the mounting seat under the radial limit of the locking block. One end of the locking block located at the T-shaped track position extends radially toward the T-shaped track to form an extension end, and the extension end is located in the sliding track of the movable pressing block to limit the sliding stroke of the movable pressing block; a locking element is installed between the extension end and the movable pressing block. The locking element of this embodiment is a spring 6; the two ends of the spring are respectively against the extension end and the movable pressing block 2.
[0029] In addition, a wedge-shaped structure is provided on one side of the mounting groove of the pressing block 2 of the present embodiment, and all the pressing blocks are surrounded by the wedge-shaped structure to form a mounting groove with a draft angle.
[0030] Furthermore, the end of the wedge-shaped structure of the pressing block is recessed radially inward to form an abutting end abutting against the product.
[0031] Working principle: When using the guide frame compatible with multiple-size products of this embodiment, first select a spring with a suitable elastic coefficient according to the type and size of the chip. Then fix the pressing block and the locking block one by one in the mounting track of the mounting seat. It should be noted here that before tightening the locking block, the spring needs to be compressed and pressed against the extension end of the pressing block and the locking block. After all four pressing blocks and the locking block are installed in the mounting seat, the installation of the guide frame components is completed. When in use, when the chip is transferred from the discharge device to the test station, the chip is slowly placed into the guide frame by the discharge device, and the four sides of the chip are in contact with the wedge-shaped slopes of the four pressure blocks at the same time. At this time, the pressure block slides in the direction away from the installation slot as the chip moves downward. The spring is compressed while the pressure block slides, and the spring deformation generates elastic potential energy. As the chip continues to move downward to a fixed position, the four sides of the chip are in contact with the abutting end of the pressure block, and the pressure block no longer slides. The pressure block presses the chip against the reaction force of the elastic potential energy of the spring to clamp the chip. Then the chip can be tested. During the test, the chip will not be displaced due to the contact of the probe, ensuring the accuracy of the test. After the test is completed, the chip is taken away by the material removal device. During the removal process, the pressure block is always in contact with the chip under the elastic force of the spring, ensuring that the chip is always evenly stressed until the chip is taken away and the pressure block is reset.
[0032] The implementation methods of the utility model are described in detail above in conjunction with the embodiments, but the utility model is not limited to the above-mentioned implementation methods. For ordinary technicians in this technical field, after knowing the contents recorded in the utility model, they can make several equivalent changes and substitutions thereto without departing from the principle of the utility model. These equivalent changes and substitutions should also be regarded as belonging to the protection scope of the utility model.
