Those skilled in the art can make similar modifications without deviating from the technical concepts of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0018] The present application provides a kind of for vehicle-mounted patch transformer joint, flat paste detection auxiliary tool (such as Figure 1The support plate 1 is provided with a front and rear distribution boss 2 in the middle part, in actual application, in order to ensure that the support plate 1 has sufficient structural strength to ensure that it will not be deformed during long-term use or during the transfer process, here, the support plate 1 and the boss 2 are of an integrated structure, and the material is 45 steel; a chip transformer placing groove 21 is arranged in the middle of the boss 2 in the front and rear direction, in actual application, the specification of the chip transformer placing groove 21 corresponds to the specification of the corresponding chip transformer that needs to be tested for pinning and flat pasting, so that the chip transformer placing groove 21 can realize the placement of the corresponding chip transformer, a plurality of pinning grooves 3 distributed along the front and rear direction of the support plate 1 are arranged at equal intervals on the left and right sides of the chip transformer placing groove 21, the pinning groove 3 can accommodate the horizontal outer end of the corresponding pin, in actual application, the outer ends of the pins on both sides of the vehicle-mounted chip transformer are horizontally distributed, so that the pin and the circuit board realize a stable pasting, thereby ensuring the stability of the power supply between the pin and the circuit board, the pinning grooves 3 on the left and right sides are symmetrically distributed and penetrate the boss 2, the pinning grooves 3 on the left and right sides are symmetrically distributed, which is convenient for corresponding to the pins symmetrically distributed on the chip transformer, thereby facilitating the simultaneous realization of pinning detection of all pins during pinning detection, and facilitating the smooth implementation of the next flat pasting detection after successful pinning detection; the center distance design standard between the front and rear of the two adjacent pinning grooves 3 is the same as the center distance design standard between the front and rear of the two pins of the detected vehicle-mounted chip transformer, for example, the center distance between the front and rear of the two adjacent pins is 6mm, and the center distance L1 of the corresponding two adjacent pinning grooves 3 is also set to 6mm; the front and rear width design standard of the pinning groove 3 is the same as the front and rear width design standard of the pin of the detected vehicle-mounted chip transformer, for example, the width of the pin is 2mm, and the width L2 of the pinning groove 3 is also 2mm, through the above design of the pinning groove 3, the width of the pinning groove 3 is adapted to the width of the corresponding pin, so that the qualified pins can be smoothly inserted into the pinning groove 3, and the standard interval distribution of the adjacent two pinning grooves 3 realizes the interval detection of the adjacent pins. During the pinning detection, when all the pins of the chip transformer can be inserted into the pinning groove 3 simultaneously, the pinning detection is passed, otherwise the pinning detection is failed, after all the pins can be inserted into the pinning groove 3 simultaneously, it can be observed whether the bottom plane of the horizontal outer end of all the pins is horizontally pasted with the upper plane 11 of the support plate, if they are pasted, the flat pasting detection is passed, thereby completing the pinning and flat pasting detection, when some pins are not pasted with the upper plane 11 of the support plate, the flat pasting detection is failed.
[0019] In practical application, the bottom plane of the vehicle-mounted chip transformer is generally in the same plane with the bottom horizontal plane of the horizontal outer end of the pin, so on the basis of the above embodiment, in order to improve the accuracy of the flat detection, the bottom plane of the chip transformer placing groove, the bottom plane 31 of the pin joint groove and the upper plane 11 of the support plate are in the same horizontal plane, which is beneficial to the stable horizontal placement of the chip transformer in the chip transformer placing groove, thereby ensuring the horizontal placement of the horizontal outer end of the pin.
[0020] Further, in order to facilitate the synchronous observation and detection of all the horizontal outer ends of the pins on one side of the chip transformer on both left and right sides of the boss 2, the length of the pin joint groove 3 in the left-right direction is less than the length of the horizontal outer end of the corresponding pin in the left-right direction, and through the above design, the horizontal outer end of the pin is exposed outside the pin joint groove 3, thereby facilitating the observation of the flatness of the horizontal outer end of the pin, for example, the length of the horizontal outer end of the pin is 8mm, and the left-right direction width distance L3 of the pin joint groove 3 is 4mm.
[0021] When the joint detection is performed, the pin of the chip transformer needs to be slowly placed into the corresponding pin joint groove 3 from top to bottom, in order to facilitate the smooth placement of the pin into the pin joint groove 3, the front and rear isolation between the front and rear adjacent two pin joint grooves 3 is realized by an isolation column 4, and a guide slope 41 is arranged on the upper front side edge and the upper rear side edge of the isolation column 4.
[0022] In practical application, two protrusions are downwardly protruded on the bottom plane of some vehicle-mounted chip transformers, in order to facilitate the protrusions not to affect the fit between the bottom of the vehicle-mounted chip transformer and the bottom plane 21 of the chip transformer placing groove, a containing hole 5 for containing the protrusions of the bottom of the chip transformer is arranged on the bottom plane 21 of the chip transformer placing groove.
