[0074] The full-automatic circuit detection device 1 includes a fixed carrier 10, a main positioning structure 20, and a sub positioning structure 30.

[0075] Please refer to Figure 2 and Figure 3 , Figure 2A perspective view of the fixing carrier 10, Figure 3 A perspective view of the fixing carrier 10, Figure 2 An enlarged view of III. The fixing carrier 10 is used to carry and clamp the circuit board to be tested. The fixing carrier 10 comprises a cover plate assembly 11, a carrying assembly 12, and a plurality of clamping assemblies 13. The cover plate assembly 11 is arranged on the carrying assembly 12. The cover plate assembly 11 comprises a cover plate 111 and a frame 112. The connecting end of the cover plate 111 is rotatably connected to the frame 112. The cover plate 111 is provided with at least two openings 1110. The two openings 1110 are respectively used to expose the main antenna structure and the auxiliary antenna structure on the circuit board to be tested relative to the cover plate assembly 11. Under the action of an external force, the cover plate 111 can rotate relative to the frame 112, thereby allowing the circuit board to be tested to be placed on the carrying assembly 12. When the cover plate 111 is clamped with the frame 112, the circuit board to be tested is clamped on the cover plate 111 and the carrying assembly 12. The frame 112 is fixedly arranged on the carrying assembly 12. The end of the frame 112 opposite to the connecting end of the cover plate 111 is clamped and fixed with the carrying assembly 12.

[0076] The carrying assembly 12 is used to carry the circuit board to be tested. The carrying assembly 12 can also be used to carry a display screen electrically connected with the circuit board to be tested. The carrying assembly 12 is provided with a display screen carrying area 122. The circuit board carrying area is used to carry the circuit board to be tested. The display screen carrying area 122 is used to carry the display screen electrically connected with the circuit board to be tested.

[0077] The clamping assembly 13 is vertically fixedly arranged on the cover plate 111 and arranged adjacent to the opening 1110. The clamping assembly 13 is clamped with the main positioning structure 20 to lock the main positioning structure 20 on the cover plate assembly 11. In at least one embodiment of the present application, the clamping assembly 13 is substantially in the shape of a trapezoidal plate. The clamping assembly 13 comprises two positioning arms 131, two connecting arms 132, and a clamping arm 134. The two positioning arms 131 are symmetrically arranged on both sides of the clamping arm 134 and connected with the clamping arm 134 through one connecting arm 132 respectively. The positioning arm 131 is provided with a fixing hole 1312. The fixing hole 1312 is used to cooperate with a fixing screw to fix the clamping assembly 13 on the cover plate assembly 11. The clamping arm 134 has a guide surface 1341. The guide surface 1341 is an inclined surface and is used to guide the moving direction of the main positioning structure 20 or the auxiliary positioning structure 30 when the main positioning structure 20 or the auxiliary positioning structure 30 is installed on the cover plate assembly 11.

[0078] Please refer to Figure 4Fig. 9 is a partial exploded view of the main positioning structure 20. The main positioning structure 20 is placed at the opening 1110 and is clamped with the cover plate assembly 11. After being clamped on the cover plate assembly 11, the main positioning structure 20 is opposite to the main antenna structure on the circuit board to be tested. The main positioning structure 20 is used to position the main adapter jig. The main positioning structure 20 comprises a main base 21, two locking components 23 and an elastic component 24.

[0079] The main base 21 comprises a main body 211, two receiving portions 212 and a main positioning portion 213. The main body 211 is generally in the shape of a cube. The lower surface of the main body 211 is inwardly recessed to form a plurality of receiving holes 2112 (as shown in Fig. 9). The plurality of receiving holes 2112 are uniformly distributed on the main body 211. In at least one embodiment of the present application, four receiving holes 2112 are formed on the main body 211 (as shown in Fig. 9). The plurality of receiving holes 2112 are used to elastically receive the elastic component 24. Figure 4 Figure 5 The two receiving portions 212 are symmetrically arranged on the two sides of the main body 211 and are embedded in the side surface of the main body 211. The receiving portion 212 comprises two oppositely arranged side walls 2121 and a positioning wall 2123. The two side walls 2121 and the positioning wall 2123 enclose a receiving groove 2124. The side walls 2121 and the positioning wall 2123 extend in a direction perpendicular to the cover plate 111 and the upper half thereof exceeds the upper surface of the main body 211. Symmetrically arranged positioning holes 2125 are formed on the two side walls 2121. The positioning holes 2125 are used to position the locking component 23 in the receiving groove 2124. The main positioning portion 213 extends from the side of the main body 211 between the two receiving portions 212 in a direction away from the main body 211. The main positioning portion 213 is provided with a main positioning groove 2131. The main positioning groove 2131 is generally in the shape of a C. The main positioning groove 2131 is used to receive and position the main adapter jig.

[0080] The two locking components 23 correspond to the two receiving grooves 2124 respectively. The locking component 23 is received in the receiving groove 2124 and the top thereof is exposed outside the receiving groove 2124. Each locking component 23 corresponds to a clamping component 13. When the locking component 23 is clamped with the corresponding clamping component 13, the main positioning structure 20 is clamped with the cover plate assembly 11. When the locking component 23 is separated from the corresponding clamping component 13, the main positioning structure 20 is separated from the cover plate assembly 11 and can rotate relative to the cover plate assembly 11. The locking component 23 comprises a clamping hook portion 231, a rotating shaft 232 and an elastic portion 234.

[0081] ​The clamping portion 231 is substantially a rectangular plate. The clamping portion 231 is rotatably fixed to the main base 21 by a rotating shaft 232. The clamping portion 231 is rotatable around the rotating shaft 232 under the action of an external force. The side of the clamping portion 231 opposite to the positioning wall 2123 is provided with a shaft hole 2311. The side of the clamping portion 231 opposite to the positioning wall 2123 is further provided with a receiving hole 2312. The receiving hole 2312 is located above the shaft hole 2311. The receiving hole 2312 is used to accommodate the elastic portion 234. The clamping portion 231 further includes a pressing end 2313 and a clamping end 2314, and the two are oppositely arranged. The pressing end 2313 is arranged away from the cover plate assembly 11 and is exposed relative to the receiving groove 2124. The pressing end 2313 serves as an operation end and is used to drive the clamping end 2314 to move away from the positioning wall 2123 when pressed by an external force. The clamping end 2314 can be accommodated in the receiving groove 2124 and is used to be clamped with the clamping assembly 13. The clamping end 2314 is substantially hook-shaped. In the locked state, the clamping end 2314 is clamped with the clamping assembly 13; in the unlocked state, the clamping end 2314 is separated from the clamping assembly 13.

[0082] The rotating shaft 232 is accommodated in the shaft hole 2311, and the two opposite ends are respectively accommodated in the positioning hole 2125.

[0083] One end of the elastic portion 234 is fixed on the positioning wall 2123, and the other end is exposed through the receiving hole 2312. The elastic portion 234 is used to be compressed and store elastic force when the clamping portion 231 is driven to move close to the positioning wall 2123 by an external force, and provide elastic force to the pressing end 2313 when the external force is removed, so as to drive the clamping portion 231 to move away from the positioning wall 2123 and restore to the initial position.

[0084] The elastic assembly 24 is used to be compressed and store elastic force when the main base 21 is driven to move close to the cover plate assembly 11 by an external force, and provide elastic force to the main base 21 when the external force is removed, so as to drive the main base 21 to move away from the cover plate assembly 11 and disconnect the electrical connection between the main adapter fixture and the main antenna structure. The elastic assembly 24 includes four elastic members 241. The four elastic members 241 are respectively accommodated in the corresponding receiving holes 2112 and one end is exposed relative to the main body 211. In at least one embodiment of the present application, the elastic member 241 is a compressible spring.

[0085] Please see Figure 6 and Figure 7 , Figure 6 for a perspective view of the secondary positioning structure 30, Figure 7Fig. 6 is a partially exploded schematic view of the sub-positioning structure 30. The sub-positioning structure 30 is opposite to the position of the sub-antenna structure on the circuit board under test, and is used to position the adapter jig electrically connected to the sub-antenna structure. The structure of the sub-positioning structure 30 is similar to that of the main positioning structure 20. The sub-positioning structure 30 includes a sub-base 31, two locking assemblies 23, and an elastic assembly 24. The structures of the locking assemblies 23 and the elastic assembly 24 in the sub-positioning structure 30 are consistent with those in the main positioning structure 20, and will not be described here. The main difference between the sub-positioning structure 30 and the main positioning structure 20 is the sub-base 31.

[0086] The sub-base 31 includes a sub-body 311, a sub-positioning portion 312, and a locking portion 314. The sub-body 311 is provided with a receiving groove 3113. The sub-body 311 is also provided with the receiving hole 2112 and has two receiving portions 212, and the specific structure and arrangement are consistent with those of the main body 211, which will not be described here. The receiving groove 3113 is provided at the edge of the sub-body 311 and is recessed inward from the upper surface of the sub-body 311. The receiving groove 3113 is approximately semicircular. The sub-positioning portion 312 is received in the receiving groove 3113 and partially exposed outside the receiving groove 3113. The sub-positioning portion 312 is used to position the sub-adapter jig so that it is opposite to the sub-antenna structure of the circuit board under test. The sub-positioning portion 312 is provided with a through hole 3121 and a sub-positioning groove 3122. The through hole 3121 is provided in the part of the sub-positioning portion 312 located in the receiving groove 3113. The sub-positioning groove 3122 is provided in the part of the sub-positioning portion 312 exposed relative to the sub-body 311 and is opposite to the sub-antenna structure of the circuit board under test fixed on the fixing carrier 10. The locking portion 314 is screwed with the sub-body 311 through the through hole 3121 to lock the sub-positioning portion 312 on the sub-body 311.

[0087] Further, the fixing carrier 10 is also provided with a plurality of wire bundling structures 14. The wire bundling structures 14 are used to bundle a plurality of connection wires electrically connected to the circuit board under test at a specified position, so that the connection wires on the full-automatic circuit detection device 1 are arranged in order. At the same time, the wire bundling structures 14 can avoid the disordered arrangement of the connection wires on the full-automatic circuit detection device 1, and can improve the efficiency when the circuit board under test is removed or connected to the external signal source. In at least one embodiment of the present application, the number of the wire bundling structures 14 can be adapted to the number of external devices needed to be connected to the circuit board under test.

[0088] The assembly process of the full-automatic circuit detection device 1 will be described below. Since the structures of the locking assemblies 23 in the main positioning structure 20 and the sub-positioning structure 30 are consistent, the operation processes of the two are also similar, and only the locking assembly 23 in the main positioning structure 20 will be described below.

[0089] When an external force is applied, the engagement between the cover plate assembly 11 and the bearing assembly 12 is released, and the cover plate assembly 11 is arranged at an angle with the bearing assembly 12. The circuit board to be tested is placed on the bearing assembly 12. Then, the cover plate assembly 11 is rotated to engage and fix the cover plate assembly 11 with the bearing assembly 12. The corresponding main adapter jig is clamped in the main positioning groove 2131 of the main positioning part 213. The main positioning structure 20 is placed at one of the openings 1110, so that the corresponding main adapter jig is opposite to the main antenna structure on the circuit board to be tested. Under the action of an external force (for example, the downward pressure provided by a mechanical hand), the hook part 231 rotates around the rotating shaft 232, the hook end 2314 moves along the guide surface 1341 to the direction close to the cover plate assembly 11, and the elastic part 234 is compressed. At the same time, the elastic member 241 accommodated in the main body 211 is compressed to store elastic force. After the hook end 2314 is separated from the guide surface 1341, the hook part 231 returns to be perpendicular to the cover plate assembly 11 under the action of the elastic part 234, so that the locking assembly 23 is engaged with the corresponding clamping arm 134. At this time, the main positioning structure 20 is fixedly arranged on the cover plate assembly 11 and located at one of the openings 1110. At the same time, the corresponding main adapter jig is electrically connected with the main antenna structure on the circuit board to be tested.

[0090] When disassembly is needed, the two pressing ends 2313 of the locking assembly 23 are driven to move towards each other under the action of an external force, the hook part 231 rotates around the rotating shaft 232, the hook end 2314 moves away from the cover plate assembly 11 under the action of the hook part 231, and the elastic part 234 is compressed. When the hook end 2314 is separated from the clamping arm 134, the elastic force stored by the elastic member 241 drives the locking assembly 23 to move away from the cover plate assembly 11, so that the locking assembly 23 is separated from the cover plate assembly 11.

[0091] The full-automatic circuit detection device 1 can ensure that the main adapter jig and the auxiliary adapter jig are respectively opposite to and electrically connected with the main antenna structure and the auxiliary antenna structure of the circuit board to be tested during the detection process through the arrangement of the main positioning structure 20 and the auxiliary positioning structure 30. The main positioning structure 20 and the auxiliary positioning structure 30 can be detachably fixed on the fixed carrier 10 through the locking assembly 23. After the main positioning structure 20 and the auxiliary positioning structure 30 are placed at the specified positions on the fixed carrier 10, the locking and fixing can be realized through the downward pressing operation of the automatic mechanical hand, and thus the automatic operation is realized.

[0092] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
