Description

Technical Field

[0001] This utility model belongs to the technical field of inspection benches, and specifically relates to a circuit module pin trimming and testing bench. Background Technology

[0002] Existing circuit module pin trimming and testing stations have significant drawbacks due to their single fixing method, making them unsuitable for trimming various circuit modules. These drawbacks primarily manifest as poor adaptability, low operational efficiency, and unstable trimming quality. Because the fixing devices of the testing station are typically designed only for circuit modules of specific shapes and sizes, they cannot effectively achieve stable fixation when dealing with modules of different specifications. This can easily lead to displacement or tilting of the modules during trimming, thereby affecting the pin trimming accuracy and the reliability of the testing results.

[0003] To address the aforementioned issues, conventional solutions include equipping each module with a dedicated fixture to improve adaptability, or employing an adjustable fixing structure to accommodate different module requirements. However, these methods have certain drawbacks: while dedicated fixtures can ensure trimming accuracy, they significantly increase equipment costs and storage space requirements, and frequent fixture changes reduce production efficiency; while adjustable fixing structures improve flexibility, in some cases improper adjustment or insufficient fixing force may lead to decreased stability, thus affecting trimming quality. Therefore, we aim to design a circuit module testing station with a novel structure to solve this problem. Utility Model Content

[0024] 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.

[0025] As the first embodiment of this utility model:

[0026] Please see Figures 1 to 5 A circuit module pin trimming and testing station includes: a repair assembly 100, a fixing assembly 200 for fixing the circuit module is fixed at the upper end of the repair assembly 100, the repair assembly 100 includes a rotating repair table 140 for rotating the structure of different fixed circuit modules, a fixing block 130 for fixing the circuit module is movably inserted on the left side of the upper surface of the rotating repair table 140, and a fixing block 150 is movably inserted on the right side of the upper surface of the rotating repair table 140.

[0027] The fixing assembly 200 includes a lifting seat 210, a connecting plate 220 is fixed on the upper side between the two lifting seats 210, and a snap-fit ​​component 230 for pressing and fixing the circuit module is movably inserted into the inner side of the upper end of the two lifting seats 210.

[0028] The maintenance assembly 100 also includes a table 110, a rotating maintenance table 140 is placed on the upper side of the output shaft of the transmission box and fixedly connected thereto, the rotating maintenance table 140 is fixed on the upper side of the table 110 through the transmission box, and the input shaft of the transmission box is connected to the drive motor through a right-angle reducer.

[0029] On the upper surface of the table 110, there are storage racks 120 on the left and right sides respectively, for placing fixing blocks 130 and 150 of different sizes. The upper surface of each storage rack 120 is recessed downward to form two rows of rectangular grooves for placing fixing blocks 130 and 150. The number of rectangular grooves is the same as the sum of the number of fixing blocks 130 and 150. In actual use, the number of fixing blocks 130 and 150 is the same. Fixing block 130 uses its rectangular groove 131 to fix the upper part of the circuit module, while fixing block 130 uses multiple slots 151 that match the pins on the circuit module to fix the lower part of the circuit module. In this way, the upper and lower parts of the circuit module to be tested and repaired can be easily fixed, which facilitates the testing and repair of the upper and lower parts of the circuit module.

[0030] The upper surface of the fixing block 130 is recessed downward to form a rectangular groove 131. The lower surface of the fixing block 130 is provided with two rubber pillars. These two rubber pillars match the two blind holes reserved on the left side of the upper surface of the table 110. In actual use, the size of the fixing block 130 and the rectangular groove 131 on it, as well as the size of the fixing block 150 and the number and distribution of the card slots 151 on it, are all compatible with a variety of common circuit modules on the market. When testing and repairing uncommon circuit modules, they are fixed by the fixing component 200.

[0031] The upper surface of the second fixing block 150 is recessed downward to form two rows of slots 151. The size and distribution of the two rows of slots 151 match the cross-sectional size and distribution of the circuit module pins. The lower surface of the first fixing block 130 is provided with two rubber pillars, which match the two blind insertion holes reserved on the right side of the upper surface of the table 110.

[0032] Specifically, by setting up a maintenance assembly 100, and by setting up a rotating maintenance table 140 on it, in actual use, a first fixing block 130 and a second fixing block 150 are set on it. Since the upper surface of the first fixing block 130 is concave downward to form a rectangular groove 131, and the upper surface of the second fixing block 150 is concave downward to form two rows of slots 151, the size and distribution of the two rows of slots 151 match the cross-sectional size and distribution of the circuit module pins. When it is necessary to grind or repair the upper part of the circuit module, the user selects a suitable second fixing block 150, fixes it on the rotating maintenance table 140, and then fixes the circuit module through its pins. In this way, the upper part of the circuit module is exposed and fixed, which facilitates subsequent polishing and repair. If the pins need to be repaired or tested, the corresponding size fixing block 130 is taken out, and then the upper part of the circuit module without pins is inverted and placed in the rectangular groove 131 of the fixing block 130. In this way, the lower part of the circuit module with pins is exposed and fixed, which facilitates subsequent repair. The setting of fixing block 130 and fixing block 2150 can quickly fix the circuit module that needs to be tested and repaired, and the two together can quickly adjust the side that needs to be repaired, which helps to improve the efficiency and convenience of pin inspection and repair of the circuit module.

[0033] As a second embodiment of this utility model:

[0034] Please see Figures 1 to 5 The lifting seat 210 includes a base plate, on the upper side of which two vertical rods are fixed. Each vertical rod has a movable block installed on its upper side. The left and right ends of the connecting plate 220 are fixedly connected to the two movable blocks respectively.

[0035] Between each pair of vertical rods, a cylinder is installed on the upper side via two movable blocks. The cylinders on the two lifting seats 210 are arranged in a mirror symmetrical structure, and the inner end of each cylinder is movably inserted into the outer end of a snap-fit ​​component 230.

[0036] The snap-fit ​​component 230 includes a plug rod 231 for inserting and connecting with the piston rod of the cylinder. A mating block 232 is fixed to the inner end of the plug rod 231. The upper surface of the mating block 232 is recessed downward to form a fixing groove 233. The inner end and the upper side of the fixing groove 233 are both designed to be open.

[0037] Based on the first embodiment described above, further, in actual use, if a circuit module of an uncommon size is encountered, the rotating inspection table 140 is activated, causing the fixing component 200 to move to the inspection position. Then, one end of the circuit module is placed in the fixing slot 233 of the snap-fit ​​component 230 on either side. Subsequently, the two cylinders are activated to bring the two snap-fit ​​components 230 closer together to fix the circuit module (the two cylinders are synchronous cylinders, and their stroke distance is controllable). The two snap-fit ​​components 230 fix the circuit module through the fixing slot 233 on them, and then subsequent inspection work can be carried out. The setting of the fixing component 200 enriches the range of pin inspection for circuit modules of different sizes, which helps to improve the flexibility of the equipment in inspection and use.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
