[0031] It should be noted that the embodiments and the features and technical solutions in the embodiments in the utility model can be combined with each other without conflict.
[0032] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0033] The utility model board SMT tray fixture's embodiment one
[0034] Please refer to Figures 1-2 The utility model board SMT tray fixture includes: fixture main part 1, the top surface of fixture main part 1 is equipped with sub -board positioning slot 101 and the mainboard positioning slot 102 in sub -board positioning slot 101 one side, and mainboard positioning slot 102 is used for the positioning of mainboard, and sub -board positioning slot 101 is used for the positioning of sub -board, to realize the board SMT of mainboard and sub -board;
[0035] Through the jig body 1, the vice plate positioning groove 101 and the main plate positioning groove 102, the main plate and the vice plate are combined to achieve the SMT production mode of the main plate and the vice plate, that is, the SMT production mode of the main plate + the first face of the vice plate sharing the jig, in the actual production scene, when the main plate and the vice plate are produced respectively, independent clamps and steel nets need to be prepared for the two, which undoubtedly increases the material procurement and management cost, and occupies a large amount of storage space, and after adopting the SMT production mode, only one set of clamp and steel net is needed, at the same time, the process of producing the main plate and the vice plate respectively and then assembling is simplified, the connection time and the operation steps of the production link are reduced, the overall production efficiency is significantly improved, furthermore, since the main plate and the vice plate have been combined and produced on the first face, the relative position of the two is preliminarily fixed, and there is no need to perform complex alignment operation, the debugging steps are greatly reduced, the defective products caused by inaccurate alignment and debugging are effectively reduced, the product direct-through rate is improved, and the production convenience and efficiency are further improved, and the production cost and quality risk are reduced.
[0036] Further, as shown in Figures 1-2 The corner of the vice plate positioning groove 101 and the main plate positioning groove 102 is provided with an avoiding groove 106, and the avoiding groove 106 is cleverly arranged to solve the corner protection problem of the main plate and the vice plate during taking and placing. On the production line, taking and placing operation is inevitable. If there is no avoiding groove 106, the corners of the main plate and the vice plate are easy to be scratched and collided with the jig. Once the corners are damaged, problems such as line breakage and component loosening of the main plate or the vice plate may occur, and even the entire product may be scrapped. The existence of the avoiding groove 106 provides sufficient space for the corners, effectively reduces the damage of the corners of the main plate and the vice plate during taking and placing, greatly improves the qualified rate of the product, guarantees the stability and continuity of the production, and reduces the economic loss and production delay caused by product damage.
[0037] Further, as shown in Figures 1-2 The bottom of the inner cavity of the vice plate positioning groove 101 and the main plate positioning groove 102 is fixedly connected with a positioning column 2, the positioning column 2 is used for inserting into the hole position on the main plate and the vice plate to limit the main plate and the vice plate, in the SMT patching and welding process, the high-precision operation of the equipment requires that the main plate and the vice plate are stably and accurately positioned, the positioning column 2 is inserted into the hole position on the main plate and the vice plate, which effectively limits the horizontal displacement of the main plate and the vice plate, reduces the problems such as component mounting deviation and inclination caused by inaccurate positioning, and further improves the accuracy and reliability of the patching, reduces the scrap rate caused by inaccurate positioning, and improves the production benefit.
[0038] Embodiment two of the combined SMT tray jig
[0039] Further, as shown in Figures 1-4As shown, the bottom of the inner cavity of the sub-plate positioning groove 101 and the main-plate positioning groove 102 is provided with an opening 107, and the opening 107 is designed for the main plate and the sub-plate with protruding components on the bottom surface. In the SMT production process, if there is no opening 107, when the main plate and the sub-plate are placed on the jig, the protruding components on the bottom surface will directly contact the bottom of the jig. In the case of slight vibration during taking, placing, transporting and production, friction and collision between the components and the jig are easily caused, which may cause the pins of the components to be deformed, broken or the surface coating to be worn, affecting the electrical performance and reliability. The existence of the opening 107 effectively avoids the direct contact between the jig and the components, provides a safe space for the protruding components, ensures the integrity and functionality of the product, greatly reduces the risk of failure caused by component damage, improves the yield of the product, and reduces the after-sales maintenance cost and customer complaints due to quality problems.
[0040] Further, as shown in Figures 1-2 Two openings 107 are provided with support members, which provide a solid support basis for the placement of the main plate and the sub-plate on the jig. In the SMT production line, the operation of various equipment will produce a certain vibration and impact force, such as the scraper movement of the solder paste printer and the suction nozzle taking and placing action of the chip mounter. The support members support the main plate and the sub-plate to maintain the stable state of the main plate and the sub-plate, ensure the accurate performance of the SMT process, and improve the production quality and consistency of the product, reduce the scrap rate caused by unstable factors in the production process, and improve the production efficiency and economic benefits.
[0041] Further, as shown in Figures 1-2 The support member is a support rod 103, which is arranged in the opening 107 and located in the middle region. Arranging the support rod 103 in the middle region has a significant advantage. Under the action of the gravity of the main plate and the sub-plate and external forces in the production process, the middle region is the most prone to deformation. Due to the lack of sufficient support in the middle, it may be concave downward, which will seriously affect the precision of the SMT production. The support rod 103 located in the middle region can effectively support the weak link of the main plate and the sub-plate, enhance the anti-deformation ability of the main plate and the sub-plate in the production process, reduce the processing error caused by deformation, improve the precision and reliability of the product, ensure that the product quality meets the high standard requirements, and reduce the rework rate and cost caused by product quality problems.
[0042] Embodiment three of the spliced board SMT tray jig
[0043] Further, as shown in Figures 1-2As shown, the side of the sub-plate positioning groove 101 and the main-plate positioning groove 102 away from each other is provided with a through opening 104, and the through opening 104 is provided for the main-plate and the sub-plate to provide a finger operation space, and the operator can easily put his fingers into the main-plate and the sub-plate, and accurately grasp the main-plate and the sub-plate, thereby improving the convenience and accuracy of taking and placing, which not only reduces the taking and placing time and improves the production efficiency, but also effectively reduces the risk of damage to the main-plate and the sub-plate due to inconvenience in taking and placing, thereby ensuring the quality of the product and the smooth production, and reducing the waste and maintenance costs caused by human operation errors.
[0044] Further, as shown in the figure, Figures 1-2 The top of the jig body 1 is provided with a groove 105, and the groove 105 is connected between the sub-plate positioning groove 101 and the main-plate positioning groove 102, and in cooperation with the through opening 104, the groove 105 provides a wider and more ergonomic finger operation space, and when the operator takes and places the main-plate and the sub-plate, the force and direction of grasping are better controlled, and the taking and placing process is more smooth and accurate, which further improves the taking and placing efficiency, shortens the production cycle of a single product, and increases the output per unit time.
[0045] Further, as shown in the figure, Figures 1-2 The jig body 1 is provided with an indication part, and the indication part is used to indicate the SMT direction. In the modern SMT production line, the production process is complex and involves the cooperation of multiple processes and equipment. For the operator, it is very important to accurately grasp the SMT direction. If there is no indication part, the operator may misplace the main-plate and the sub-plate due to misunderstanding of the production direction, or perform the process such as patching and welding in the wrong direction during SMT operation, which will cause serious quality problems in the produced products, such as component reverse patching and welding misplacement, etc. A large amount of waste will cause material waste, production time delay and cost increase, and the indication part can clearly and intuitively indicate the SMT direction for the operator, ensuring that the operator can operate in the correct direction at each link, improving the production accuracy and one-time pass rate, reducing material waste, production stagnation and rework costs caused by incorrect direction, and ensuring efficient and orderly production.
[0046] Further, as shown in the figure, Figures 1-2 The indication part is an indication arrow 3, which is arranged on the top of the jig body 1, and the indication arrow 3 has a high visual recognition degree as an indication part. In the complex environment of the production workshop, the operator needs to quickly and accurately obtain the SMT direction information, so that the worker can quickly understand the SMT direction requirement.
[0047] In use, the main plate is placed in the main plate positioning groove 102, the auxiliary plate is placed in the auxiliary plate positioning groove 101, the hole positions on the main plate and the auxiliary plate are inserted and positioned with the positioning columns 2, and then SMT is performed.
[0048] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The preferred embodiments of the present application are shown in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
