DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0032] Please refer to Figures 1-7In the embodiment of the application, a universal charger turnover jig applied to an electronic detection system is used for batch positioning and leading out test terminals of chargers 1 in the electronic detection system, so that the batch positioned chargers 1 can be turned over in the electronic detection system to realize semi-automatic or fully automatic operation of the charger 1 electronic detection system. In the universal technical solution of the turnover jig, the turnover jig comprises a base 10 and at least one quick-change plate 20 arranged above the base 10. A plurality of material placing grooves 11 for placing the chargers 1 are formed in the base 10. A replaceable silica gel sheath 30 is arranged in each material placing groove 11. The silica gel sheath 30 is used for controlling the height of the charger 1 and positioning the charger 1. A fixing part 12 is also arranged beside each material placing groove 11 on the base 10. The fixing part 12 is provided with a plurality of first conductive contacts 121 facing upward and a USB connecting terminal 122 electrically connected to the first conductive contacts 121. The USB connecting terminal 122 is used for connecting the output end of the charger 1 positioned on the silica gel sheath 30. An elevated seat 13 is also arranged on the base 10. The elevated seat 13 is provided with a positioning buckle 14 connected to the quick-change plate 20. The quick-change plate 20 is arranged above the material placing groove 11 through cooperation with the positioning buckle 14. A plurality of conductive probes 21 facing downward and connected to the input end of the charger 1 and a plurality of second conductive contacts 22 facing upward and electrically connected to the conductive probes 21 are arranged on the quick-change plate 20.

[0033] The technical solution is mainly used for turning over this type of charger 1 with the output end and the input end arranged on two adjacent right-angled surfaces. The USB connecting terminal 122 and the conductive probe 21 are arranged according to the direction of the input end and the output end of the charger 1. The USB connecting terminal 122 is commonly a usb type-c connecting terminal, but it can also be other types of connecting terminals, which are configured according to actual needs. The working principle is as follows:

[0034] The corresponding silicone sheath 30 is pre-configured according to the size of the charger 1, and then the charger 1 produced on the previous assembly line is positioned and placed on the silicone sheath 30. During the placement process, the output end of the charger 1 is docked with the USB connection terminal 122. After placement, the charger 1 can be firmly grasped and positioned by the material properties of the silicone sheath 30 itself. Then, the corresponding quick-change plate 20 is configured according to the specifications of the charger 1, and the quick-change plate 20 is fixed to the lifting seat 13 through the positioning buckle 14. After fixation, the conductive probe 21 can be docked with the output end (pin) of the charger 1. In order to ensure the reliability of the electrical connection after docking, the probe of the conductive probe 21 adopts an elastic and retractable structure design, and the probe is also expanded to ensure full contact with the pin of the charger 1; after the charger 1 is positioned and the test end is brought out through the USB connection terminal 122 and the conductive pin, the charger 1 turnover fixture can be used in the electronic testing system. The electronic testing process can detect the charger 1 on the fixture by docking the first conductive contact 121 and the second conductive contact 22.

[0035] In the above technical solution, by cleverly utilizing the structural features of the output and input ends of the charger 1 and based on the structural features of the USB Type-C interface commonly used at the output end of the current charger 1, the structure of the output end of the charger 1 is uniformly set, and then the optional silicone sheath 30 is used to adapt to chargers 1 of different sizes. The silicone sheath 30 can control the output end of the charger 1 at the same position, so that chargers 1 of different sizes can be docked with the USB connection terminal 122 at the same position; on this basis, a quick-change plate 20 is used to set a conductive probe 21 that is docked to the input end of the charger 1. The quick-change plate 20 is detachably set by using a lifting seat 13 in combination with a positioning buckle 14, so that the turnover fixture can be selectively configured with a quick-change plate 20 of corresponding specifications according to chargers 1 of different specifications.

[0036] This arrangement eliminates the need for adjustment structures between adjacent chargers 1 for chargers 1 of different sizes, allowing multiple chargers 1 to be positioned closely together on the same turnover jig. This allows the turnover jig of the same size using this technical solution to accommodate a greater number of chargers 1.

[0037] In terms of replacement convenience, the silicone sheath 30 itself has certain deformation characteristics and can be directly put into the discharge trough 11 without the need for other fixing structures, making it easy to disassemble and assemble. The quick-change plate 20 adopts a snap-on structure to achieve disassembly and assembly, which can also achieve the purpose of quick disassembly and assembly. In addition, for chargers 1 of different sizes and specifications, there is no need to remove the base 10 fixed to the device. Instead, chargers 1 of other sizes and specifications can be adapted by simply replacing the silicone sheath 30 and the quick-change plate 20, thereby effectively reducing the downtime of the electronic detection system.

[0038] In detection, the first conductive contact 121 and the second conductive contact 22 are arranged upwardly, so that the charger 1 turntable can be docked with the first conductive contact 121 and the second conductive contact 22 from the same direction in the detection equipment, and the detection equipment can more conveniently dock the charger 1 turntable.

[0039] Please refer to Figures 6-7On the basis of the above technical solutions, preferably, the silica gel sheath 30 has a base 31 and a positioning edge 32 formed around the base 31, the silica gel sheath 30 controls the height of the charger 1 by changing the thickness of the base 31, and the silica gel sheath 30 positions the charger 1 by changing the thickness of the positioning edge 32. In order to facilitate the disassembly and assembly of the silica gel sheath 30, the silica gel sheaths 30 of adjacent discharge grooves 11 are connected by the positioning edges 32, so that multiple silica gel sheaths 30 can be connected together, thereby facilitating unified disassembly and assembly and unified storage. In terms of size, the discharge groove 11 obtains the size range of the charger 1 according to the size of the charger 1, sets the maximum size as the size of the discharge groove 11, and when the charger 1 has the maximum height, the silica gel sheath 30 can not be provided with the base 31 but only with the positioning edge 32. When the charger 1 has the maximum width and length, the silica gel sheath 30 can not be provided with the positioning edge 32 but only with the base 31. When the charger 1 has the maximum height, width and length, the silica gel sheath 30 can not be used directly, and the charger 1 can be directly placed in the discharge groove 11. In terms of height, the discharge groove 11 satisfies that the output end of the charger 1 can be higher than the base 10 after being placed in the discharge groove 11, so that the output end of the charger 1 can be horizontally connected with the USB connecting terminal 122. The silica gel sheath 30 needs to position the charger 1 to a certain extent, and the height thereof can be set to cover the output end of the charger 1, and then a notch 33 is formed at one end of the silica gel sheath 30 along the positioning edge 32 for the output end of the charger 1 to be connected with the USB connecting terminal 122.In addition, in order to make the charger 1 output end and the USB connecting terminal 122 dock more smoothly in the process of positioning the charger 1 in the silica gel sheath 30, the other end of the silica gel sheath 30 is extended to form a reserved section 34, which is used for placing the charger 1 and then pushing to make the charger 1 output end and the USB connecting terminal 122 dock. Through this setting, the charger 1 output end and the USB connecting terminal 122 can be docked by placing the charger 1 in the silica gel sheath 30 and then pushing horizontally. In addition, the positioning edge 32 is internally formed with reinforcing ribs 35 for abutting against both sides of the charger 1. The base 31 is formed with a sliding strip 36 for assisting the pushing operation after the charger 1 is placed, which can make the charger 1 slide more smoothly in the process of positioning in the silica gel sheath 30. The reinforcing ribs 35 are located close to the gap 33 and away from the reserved section 34, so that the charger 1 does not contact the reinforcing ribs 35 when being placed in the silica gel sheath 30, but is pressed by the reinforcing ribs 35 in the process of pushing the charger 1 to dock the output end with the USB connecting terminal 122, so that the charger 1 can be pushed to dock the USB connecting terminal 122 more smoothly, and after docking the USB connecting terminal 122, the charger 1 can be tightly abutted by the reinforcing ribs 35 with greater force, so that the charger 1 can be firmly constrained by the silica gel sheath 30 after being completely positioned in the silica gel sheath 30. Therefore, the above ingenious structural design of the silica gel sheath 30 can make the operation of positioning the charger 1 in the charger 1 rotating jig more convenient and efficient.

[0040] Please refer to Figure 6 On the basis of the above technical solution, preferably, the fixing member 12 comprises a lower shell 123 and an upper shell 124 fixedly covered with each other, a first PCBA board 125 is arranged between the lower shell 123 and the upper shell 124, and the first conductive contact 121 and the USB connecting terminal 122 are integrally arranged on the first PCBA board 125. The quick-change board 20 is provided with a second PCBA board 23, and the conductive probe 21 and the second conductive contact 22 are integrally arranged on the PCBA board. The first conductive contact 121 and the second conductive contact 22 are made of conductive material, such as copper column, which can be directly welded on the PCBA board. The first PCBA board 125 is fixed by the lower shell 123 and the upper shell 124, so that the first PCBA board 125 can be firmly arranged on the base 10, and the firmness of the charger 1 output end and the USB connecting terminal 122 docking is ensured.

[0041] Please refer to Figures 1-4On the basis of the above technical scheme, the plurality of feeding grooves 11 are uniformly arranged into at least one row, preferably two rows in the figure, and the lifting seats 13 are arranged in pairs and located on both sides of the whole row of feeding grooves 11. The two ends of the quick-change plate 20 are butted against the positioning buckles 14 on the lifting seats 13, so that the quick-change plate 20 is arranged directly above the whole row of feeding grooves 11. In the position design of the fixing member 12, the fixing member 12 is located between the two rows of feeding grooves 11, so that the overall structure is compact, and the charger 1 is convenient to position and place. The positioning buckle 14 comprises a positioning seat 141 mounted on the lifting seat 13 and a rotating shaft seat 142. The positioning seat 141 is provided with a positioning pin 143 butted against the quick-change plate 20. The rotating shaft seat 142 is rotatably connected with a turnover buckle 144. The turnover buckle 144 and the rotating shaft seat 142 are provided with a spring 145. The two ends of the quick-change plate 20 are in clamping cooperation with the turnover buckle 144. The turnover buckle 144 is provided with a slope guiding structure, so that when the quick-change plate 20 is clamped, the turnover buckle 144 does not need to be bent, and only needs to be put into the quick-change plate 20 along the positioning pin 143. The turnover buckle 144 will be automatically guided to clamp the quick-change plate 20. When the quick-change plate 20 is removed, the turnover buckle 144 is bent, and the quick-change plate 20 can be easily taken out. In addition, the lower end of the quick-change plate 20 is also provided with a supporting rod member 24 for abutting against the base 10. The supporting rod member 24 is in cooperation with the feeding groove 11, which can enhance the firmness and reliability of the cooperation between the quick-change plate 20 and the base 10.

[0042] It will be obvious to a person skilled in the art that, without departing from the spirit or essential characteristics of the application, the present application can be implemented in other specific forms. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
