Technical Field
[0001] The utility model relates to the technical field of electronic detection, in particular to a fixture structure for detecting electronic products. Background Art
[0002] Electronic product testing fixtures are specialized tools used to secure and position electronic components or circuit boards for various electrical performance, functional, and aging tests. Fixture design typically requires consideration of accuracy, versatility, stability, rapid replacement, safety, and affordability. While meeting testing requirements, fixture design should minimize costs. The design and manufacture of electronic product testing fixtures typically requires close collaboration with test engineers, mechanical engineers, and electronics engineers to ensure the fixture meets specific testing requirements.
[0003] Existing fixtures are generally customized, and one fixture only has one clamping effect. When the parts in different steps of the same process are the same but the clamping methods are different, another fixture needs to be prepared. When in use, the fixture structure needs to be further processed and improved, which increases the number of steps and reduces work efficiency. For this reason, the inventors have proposed a fixture structure for electronic product testing to solve the above-mentioned technical problems. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.
[0005] A fixture structure for electronic product testing includes a clamp seat, a clamp head and a sleeve, the clamp seat and the clamp head are an integrally formed structure, the clamp head is in an inwardly concave arc shape, the clamp head and the sleeve are detachable, the sleeve and the clamp head have the same curvature, a connecting groove for matching with the clamp head is provided in the middle of the sleeve, a connecting hole is provided on the surface of the clamp head, a connecting rod for matching with the connecting hole is provided on the surface of the connecting groove, a protective pad for assisting in clamping electronic products is installed at the end of the sleeve away from the connecting groove, the protective pad is in a convex shape, and the protective pad structure is symmetrically arranged at one end of the sleeve, a splint for assisting in clamping electronic products is provided at one end of the clamp head, one end of the splint is in a flat plate shape, and the splint and the clamp head are detachable.
[0006] Furthermore, one end of the clamping seat is connected to an anti-skid pad, and the surface of the anti-skid pad is provided with a plurality of anti-skid grooves for increasing friction. The anti-skid grooves are higher than the surface of the anti-skid pad, and the distance between two adjacent anti-skid pads is equidistant.
[0007] The anti-slip pad and anti-slip grooves can ensure that the force application points are increased during use, so that the friction between the anti-slip pad and the contact surface is uniform, thereby improving the stability and grip of the clamp. The anti-slip grooves further increase the force application points and reduce the probability of slipping during use. The equidistant structure also helps to distribute the force evenly and further increase the uniform friction.
[0008] Furthermore, the clamping seat and the clamping head are installed in pairs, the clamping seats are connected by locking screws, and two adjacent clamping seats are installed in a cross-arrangement;
[0009] The cross-mounting of two adjacent clamps can improve the stability and load-bearing capacity of the clamping system. The cross-mounting makes the connection between the clamps more secure, can evenly disperse the force, and reduce deformation or damage caused by excessive force on a single point. In addition, this structure can increase the clamping range, improve the clamping efficiency, and make the chuck more flexible during operation and adapt to workpieces of different sizes and shapes. At the same time, the cross-mounted clamps are more efficient in space utilization, which helps to save installation space and make the overall structure more compact. The installation method using locking screws facilitates quick disassembly between the clamps. When a single clamp or chuck surface is damaged, the clamp and chuck on one side can be replaced without replacing them in pairs. This reduces maintenance costs while saving costs and reducing processes, thereby improving work efficiency.
[0010] Furthermore, the edge of the chuck is provided with a plurality of teeth for increasing friction, the teeth are convex, the spacing between two adjacent teeth is equal, the surface of the connecting groove is provided with a pad for mounting in pair with the teeth, and the length of the connecting rod is set to avoid the installation position of the teeth, so as to avoid conflict between the chuck and the sleeve when the connecting rod is installed in the connecting hole, and at the same time avoid installation conflict between the connecting rod and the teeth;
[0011] The teeth help to grasp electronic products with curved surface structures, reducing the impact of electronic products falling or displacement that affects their detection accuracy, while the pad at one end of the sleeve prevents the sleeve from scratching the surface of the electronic product, further protecting the surface accuracy of the electronic product. When the chuck is connected to the sleeve, the teeth and the pad engage with each other, and the sleeve prevents the teeth from scratching the surface of the electronic product. During rough processing, the teeth can be used to grasp and clamp, which increases the gripping force and detection accuracy. When performing fine detection, the surface accuracy of the electronic product can be further protected by connecting the sleeve to facilitate the fine detection process.
[0012] Furthermore, the splint is connected to one end of the chuck via a rotating shaft, one end of the splint is a pressure block, the surface of the splint is provided with a reinforcing rib for increasing the supporting force of the splint to prevent deformation, the rotating shaft passes through the surfaces of both ends of the reinforcing rib, one end of the splint is in a convex shape, and the angle with the clamping end of the chuck is consistent, and the convex structure prevents the splint from having uneven clamping force or slipping when the chuck is connected to the splint;
[0013] The shaft reinforcement ribs can ensure that when the splint is subjected to pressure or torsion, there is good fixation and support between the shaft and the reinforcement ribs, thereby improving the overall structural stability of the splint and preventing deformation or damage due to stress concentration during use. At the same time, the presence of the reinforcement ribs increases the rigidity of the splint, making the chuck more stable when clamping objects, thereby improving the performance and reliability of the clamp.
[0014] Furthermore, one end of the flat plate is provided with a plurality of anti-slip grooves for assisting in gripping objects, the anti-slip grooves are concave in structure, and the distance between two adjacent anti-slip grooves is equidistant;
[0015] The anti-slip groove ensures that the clamp can apply uniform pressure when clamping electronic products of different sizes and shapes, thereby improving the stability and safety of the clamp. The equidistant setting also simplifies the design and manufacturing process of the clamp, reduces production costs, and makes the clamp more intuitive and easy to use. The flat-shaped clamp helps to clamp electronic products with flatness, reducing the impact of electronic products falling or displacement on their detection accuracy.
[0016] Compared with the prior art, the present invention has the following beneficial effects: a simple structure is used to complete a variety of different clamping processes; the concave arc-shaped chuck can clamp electronic products with curved surface structures; during rough processing, the chuck curved surface clamping method can be used to improve the clamping force and detection accuracy; the pad at one end of the jacket prevents the jacket from scratching the surface of the electronic product, further protecting the surface accuracy of the electronic product; when performing fine testing, the surface accuracy of the electronic product is further protected by connecting the jacket, so as to facilitate the fine testing process;
[0017] When the clamping plate is not installed at the front end of the chuck, it can grip soft plastic products. When the clamping plate is installed, the flat shape of the clamping plate helps to grip flat electronic products, reducing the probability of electronic products falling or moving and affecting their detection accuracy.

DETAILED DESCRIPTION
[0029] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0030] For this example, please refer to Figures 1-9The specific implementation of the fixture structure for electronic product testing includes a clamp base 1, a clamp head 2 and a sleeve 3. The clamp base 1 and the clamp head 2 are an integrally formed structure, the clamp head 2 is in the shape of an inward concave arc, the clamp head 2 and the sleeve 3 are detachable, the sleeve 3 and the clamp head 2 have the same curvature, a connecting groove 4 is provided in the middle of the sleeve 3 for matching with the clamp head 2, a connecting hole 5 is provided on the surface of the clamp head 2, and a connecting rod 6 is provided on the surface of the connecting groove 4 for matching with the connecting hole 5. A pad 7 for assisting the clamping of electronic products is installed at the end of the sleeve 3 away from the connecting groove 4. The pad 7 is in a convex shape, and the pad 7 is symmetrically arranged at one end of the sleeve 3. A splint 8 for assisting the clamping of electronic products is provided at one end of the clamp head 2. One end of the splint 8 is in the shape of a flat plate, and the splint 8 and the clamp head 2 are detachable.
[0031] One end of the clamping base 1 is connected to an anti-skid pad 9, and the surface of the anti-skid pad 9 is provided with a plurality of anti-skid grooves 10 for increasing friction. The anti-skid grooves 10 are higher than the surface of the anti-skid pad 9, and the distance between two adjacent anti-skid pads 9 is equidistant.
[0032] The anti-slip pad 9 and the anti-slip groove 10 can ensure that the force application points are increased during use, so that the friction between the anti-slip pad 9 and the contact surface is uniform, thereby improving the stability and gripping effect of the clamp 1, and the anti-slip groove 10 further increases the force application points and reduces the probability of slipping during use. The equidistant structure also helps to distribute the force evenly and further increase the uniform friction.
[0033] The clamping base 1 and the clamping head 2 are installed in pairs, the clamping base 1 is connected by a locking screw 11, and two adjacent clamping bases 1 are installed in a cross-arrangement;
[0034] The cross-mounting arrangement of two adjacent clamps 1 can improve the stability and load-bearing capacity of the clamping system. The cross-mounting makes the connection between the clamps 1 more secure, can evenly disperse the force, and reduce deformation or damage caused by excessive force on a single point. In addition, this structure can increase the clamping range, improve the clamping efficiency, and make the chuck 2 more flexible during operation and adapt to workpieces of different sizes and shapes; at the same time, the cross-mounted clamps 1 are more efficient in space utilization, which helps to save installation space and make the overall structure more compact; and the installation method using locking screws 11 facilitates quick disassembly between the clamps 1. When the surface of a single clamp 1 or chuck 2 is damaged, the clamp 1 and chuck 2 on one side can be replaced without replacing them in pairs, which reduces maintenance costs while saving costs and reducing processes, thereby improving work efficiency.
[0035] The edge of the chuck 2 is provided with a plurality of teeth 12 for increasing friction. The teeth 12 are convex, and the spacing between two adjacent teeth 12 is equal. The surface of the connecting groove 4 is provided with a pad 13 for mounting in pair with the teeth 12. The length of the connecting rod 6 is set to avoid the installation position of the teeth 12, so as to avoid the conflict between the chuck 2 and the sleeve 3 when the connecting rod 6 is installed in the connecting hole 5, and at the same time avoid the installation conflict between the connecting rod 6 and the teeth 12.
[0036] The latch 12 helps to grasp electronic products with a curved surface structure, reducing the impact of electronic products falling or displacement that affects their detection accuracy, and the protective pad 7 at one end of the sleeve 3 prevents the sleeve 3 from scratching the surface of the electronic product, further protecting the surface accuracy of the electronic product. When the chuck 2 is connected to the sleeve 3, the latch 12 and the pad 13 engage with each other, and at the same time the sleeve 3 prevents the latch 12 from scratching the surface of the electronic product. During rough processing, the latch 12 can be used to clamp the product to improve the clamping force and detection accuracy. When performing fine detection, the surface accuracy of the electronic product can be further protected by connecting the sleeve 3 to facilitate the fine detection process.
[0037] The splint 8 is connected to one end of the chuck 2 via a rotating shaft 14. One end of the splint 8 is a pressing block 15. The surface of the splint 8 is provided with a reinforcing rib 16 for increasing the supporting force of the splint 8 to prevent deformation. The rotating shaft 14 passes through the surfaces of both ends of the reinforcing rib 16. One end of the splint 8 is in a convex shape and is consistent with the angle of the clamping end of the chuck 2. The convex structure prevents the splint 8 from having uneven clamping force or slipping when the chuck 2 is connected to the splint 8.
[0038] The reinforcing ribs 16 of the rotating shaft 14 can ensure that the splint 8 is well fixed and supported by the rotating shaft 14 and the reinforcing ribs 16 when subjected to pressure or torsion, thereby improving the overall structural stability of the splint 8 and preventing deformation or damage due to stress concentration during use. At the same time, the presence of the reinforcing ribs 16 increases the rigidity of the splint 8, making the chuck 2 more stable when clamping an object, thereby improving the performance and reliability of the clamp.
[0039] The clamping plate 8 is provided with a plurality of anti-slip grooves 17 at one end thereof for assisting in gripping objects. The anti-slip grooves 17 are concave in structure, and the distance between two adjacent anti-slip grooves 17 is equidistant.
[0040] The anti-slip groove 17 can ensure that the clamping plate 8 can apply pressure evenly when clamping electronic products of different sizes and shapes, thereby improving the stability and safety of the clamping. The equidistant setting also simplifies the design and manufacturing process of the clamping plate 8, reduces production costs, and makes the clamping plate 8 more intuitive and easy to use. The flat-plate shape of the clamping plate 8 helps to clamp electronic products with flatness, reducing the effect of electronic products falling or displacing and affecting their detection accuracy.
[0041] The key points of the design of the present invention are: a simple structure is used to complete a variety of different clamping processes; the concave arc-shaped chuck 2 can clamp electronic products with curved surface structures; during rough processing, the clamping teeth 12 can be used to clamp, thereby improving the clamping force and detection accuracy; the protective pad 7 at one end of the jacket 3 prevents the jacket 3 from scratching the surface of the electronic product, further protecting the surface accuracy of the electronic product; when performing fine testing, the surface accuracy of the electronic product is further protected by connecting the jacket 3, so as to facilitate the fine testing process;
[0042] When the clamping plate 8 is not installed at the front end of the clamping head 2, it can grip products made of soft plastic materials. When the clamping plate 8 is installed, the flat shape of the clamping plate 8 helps to grip electronic products with flatness, reducing the probability of electronic products falling or moving and affecting their detection accuracy.
[0043] The process of plane clamping or arc clamping is completed through a simple structure, which reduces the manufacturing cost while compressing the fixture structure. The detachable structure further increases the flexibility and installation ease of the fixture, improves the installation efficiency, and plays a role in improving work efficiency.
