Description

Technical Field

[0001] The present invention relates to the technical field of electronic detection, and in particular to a universal charger turnover fixture used in an electronic detection system. Background Art

[0002] The charger turnover fixture is a key auxiliary tool in the electronic testing system. It is used for handling, positioning and testing of chargers to ensure the stability and consistency of the testing process. Its main functions include precise fixation, electrical connection, protection of chargers and improved testing efficiency. It is widely used in production line testing, quality control and R&D testing. The fixture design needs to focus on precision, durability, compatibility and safety to ensure the accuracy of the test results and meet the needs of different models of chargers. Through standardized design, the charger turnover fixture significantly improves the testing efficiency and quality control level.

[0003] However, in electronic detection systems, in order to improve detection efficiency and enable detection equipment to meet the detection of chargers of different sizes or specifications, people have increasingly higher requirements for the universal design of the system. At present, some compatibility designs have also been introduced in charger turnover jigs. Through adjustable positioning blocks and clamping devices, the jig can adapt to chargers of various sizes and shapes. The adjustment range of the positioning blocks can cover the length, width and height dimensions of common chargers, meeting the turnover needs of chargers of different brands and models.

[0004] However, the inventors have found that these compatibility designs will greatly increase the overall complexity of the fixture, especially the adjustable designs of the positioning blocks and clamping devices. These structures will occupy a large area on the fixture, resulting in the same size fixture being unable to accommodate multiple chargers at the same time; in addition, there are great differences in the specifications of charger pins in some different countries, resulting in the need to set up turnover fixtures of different specifications for chargers of different specifications, which will increase the cost of the fixture and occupy a large space in the workshop. Moreover, when the installation of the turnover fixtures set on some equipment in the electronic detection system is more troublesome, the operation of replacing the entire turnover fixture will cause the electronic detection system to be down for a long time, affecting the work efficiency of the entire production line. Therefore, it is necessary to propose an improved technical solution to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-7In an embodiment of the present invention, a universal charger turnover fixture used in an electronic detection system is used to position chargers 1 in batches in the electronic detection system and lead out test terminals, so that the chargers 1 positioned in batches can be turned over in the electronic detection system to achieve semi-automatic or fully automatic operation of the electronic detection system of the charger 1; in the universal technical solution setting of the turnover fixture, the turnover fixture includes a base 10 and at least one quick-change plate 20 arranged above the base 10, and a plurality of discharge troughs 11 for placing the chargers 1 are provided on the base 10, and a replaceable silicone sheath 30 is provided in each discharge trough 11, and the silicone sheath 30 is used to control the height of the charger 1 and position the charger 1; A fixing part 12 is also provided on the base 10 beside each discharge trough 11. The fixing part 12 is provided with a plurality of first conductive contacts 121 facing upward and a USB connection terminal 122 electrically connected to the first conductive contact 121. The USB connection terminal 122 is used to dock with the output end of the charger 1 positioned on the silicone sheath 30. A lifting seat 13 is also provided on the base 10. A positioning buckle 14 docking with the quick-change plate 20 is provided on the lifting seat 13. The quick-change plate 20 corresponds to the top of the discharge trough 11 by cooperating with the positioning buckle 14. A plurality of conductive probes 21 facing downward and docking with 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 provided on the quick-change plate 20.

[0023] This technical solution is mainly used for rotating the charger 1 of this type whose output and input terminals are arranged at two adjacent right-angled surfaces. The corresponding USB connection terminal 122 and the conductive probe 21 are arranged according to the direction of the input and output terminals of this type of charger 1. The USB connection terminal 122 generally adopts a USB type-C connection terminal, and can also be other types of connection terminals, which are configured according to actual needs. The working principle is as follows: The corresponding silicone sheath 30 is pre-configured according to the size of the charger 1, and then the charger 1 manufactured 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, and 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 structural 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 led out through the USB connection terminal 122 and the conductive pin, the charger 1 turnover fixture can be used in the electronic detection system, and the electronic detection process can detect the charger 1 on the fixture by docking the first conductive contact 121 and the second conductive contact 22.

[0024] 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 conductive probe 21 docked at the input end of the charger 1 is set by using a quick-change plate 20, which uses a lifting seat 13 combined with a positioning buckle 14 to detachably set the quick-change plate 20, so that the turnover fixture can selectively configure a quick-change plate 20 of corresponding specifications according to chargers 1 of different specifications.

[0025] Through this arrangement, in terms of compactness, the adjustment structure required for chargers 1 of different sizes is removed between adjacent chargers 1, which can achieve that multiple chargers 1 are positioned closely on the same turnover fixture, so that the turnover fixture using the technical solution of the same size can accommodate more chargers 1; In terms of replacement convenience, the silicone sheath 30 itself has certain deformation characteristics and can be directly sleeved in the discharge trough 11 without setting other fixing structures, and its disassembly and assembly are convenient; and 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, and for chargers 1 of different sizes and specifications, it is not necessary to disassemble the base 10 fixed on the device, but only by simply replacing the silicone sheath 30 and the quick-change plate 20, it can adapt to chargers 1 of other sizes and specifications, thereby effectively reducing the downtime of the electronic detection system; In detection, by using the first conductive contact 121 and the second conductive contact 22 set upward, the charger 1 turnover jig can be docked with the first conductive contact 121 and the second conductive contact 22 from the same direction in the detection device, so that the detection device can more conveniently dock with the charger 1 turnover jig.

[0026] See also Figure 6-7On the basis of the above technical solution, the silicone sheath 30 preferably has a base 31 and a positioning edge 32 formed around the base 31. The silicone sheath 30 controls the height of the charger 1 by changing the thickness of the base 31, and the silicone 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 silicone sheath 30, the silicone sheaths 30 of adjacent discharge troughs 11 can be arranged in a connected manner through the positioning edge 32, so that multiple silicone sheaths 30 can be connected together, thereby facilitating unified disassembly and assembly and unified storage; in terms of size setting of the discharge trough 11, the size range of the charger 1 is obtained according to the size of different chargers 1, and the maximum size is set to the size of the discharge trough 11. When the height of the charger 1 is the largest, the silicone sheath 30 can be provided without the base 31 and only retain Positioning edge 32; when the width and length of the charger 1 are at the maximum, the positioning edge 32 may not be set and only the base 31 may be retained; when the height, width and length of the charger 1 are at the maximum, the silicone sheath 30 may not be used directly, and the charger 1 may be directly placed in the discharge trough 11; the height of the discharge trough 11 is designed to ensure that the output end of the charger 1 can be higher than the base 10 after the charger 1 is placed therein, thereby ensuring that the output end of the charger 1 can be laterally docked with the USB connection terminal 122, and the silicone sheath 30 needs to position the charger 1 to a certain extent, and its height can be set to cover the output end of the charger 1, and then a notch 33 is opened at one end of the silicone sheath 30 along the positioning edge 32 for docking the output end of the charger 1 with the USB connection terminal 122.In addition, in order to enable the output end of the charger 1 to be more smoothly connected to the USB connection terminal 122 during the process of positioning the charger 1 in the silicone sheath 30, the other end of the silicone sheath 30 is extended to form a reserved section 34, and the reserved section 34 is used for pushing the charger 1 after it is placed in order to connect the output end of the charger 1 with the USB connection terminal 122. Through this arrangement, the charger 1 can be placed in the silicone sheath 30 and then pushed horizontally to connect the output end of the charger 1 with the USB connection terminal 122; in addition, the inner side of the positioning edge 32 is formed with a reinforcing rib 35 for tightening the two sides of the charger 1; the base 31 is formed with a slide bar 36 for pushing the auxiliary charger 1 after it is placed in, which can enable the charger 1 to be positioned in the silicone sheath 30. The reinforcing rib 35 is located close to the notch 33 and away from the reserved section 34, so that the charger 1 will not contact the reinforcing rib 35 when it is placed in the silicone sheath 30, and is squeezed by the reinforcing rib 35 in the process of pushing the charger 1 so that its output end is connected to the USB connection terminal 122, so that the charger 1 can be pushed and connected to the USB connection terminal 122 more smoothly, and after the USB connection terminal 122 is connected, the reinforcing rib 35 can be used to tighten the charger 1 with greater force, so that the charger 1 can be firmly constrained by the silicone sheath 30 after it is fully positioned on the silicone sheath 30; therefore, the above-mentioned ingenious structural design of the silicone sheath 30 can make the operation of positioning the charger 1 on the charger 1 turnover fixture more convenient and efficient.

The first conductive contact 121 and the second conductive contact 22 are made of conductive materials, such as copper pillars, and 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 set on the base 10, ensuring the firmness of the connection between the output end of the charger 1 and the USB connection terminal 122.
