[0089] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 is a schematic perspective view of a circuit board carrying jig according to an embodiment of the present application; Figure 2 is a schematic cross-sectional view of the circuit board carrying jig shown in Figure 1 along line A-A; Figure 3 is a schematic perspective view of a locking assembly in a locked state according to an embodiment of the present application; Figure 4is a perspective view of a locking assembly in an unlocked state according to an embodiment of the present application. An embodiment of the present application provides a circuit board carrying jig 1, which includes a connecting plate 11, a locking assembly 12, and an unlocking assembly 13. The locking assembly 12 includes a support 122, a pin 121, and a ball 123. The support 122 has a receiving cavity 122a and a through hole 122b, which communicates with the receiving cavity 122a. One end of the support 122 is fixedly connected to the connecting plate 11, and the other end is used to extend into a board hole of a circuit board. The pin 121 is partially received in the receiving cavity 122a and is movable relative to the support 122. The ball 123 cooperates with the pin 121 to enable the locking assembly 12 to have a locked state in which the ball 123 partially extends out of the through hole 122b, and an unlocked state in which the ball 123 is received in the receiving cavity 122a. The unlocking assembly 13 includes a pressing plate 131, which is located on a side of the connecting plate 11 that is away from the ball 123. The pressing plate 131 is used to drive the pin 121 to move in the receiving cavity 122a in a direction away from the pressing plate 131, so that the locking assembly 12 changes from the locked state to the unlocked state.

[0090] It can be understood that the circuit board carrying jig 1 provided by an embodiment of the present application is a circuit board extraction circuit board carrying jig 1. The extracted circuit board has a circuit board hole that can cooperate with the circuit board carrying jig 1. The locking assembly 12 of the circuit board carrying jig 1 can extend into the board hole of the circuit board and lock the circuit board carrying jig 1 and the extracted circuit board. The extraction and movement of the circuit board carrying jig 1 can achieve the extraction, movement, carrying, and assembly of the extracted circuit board. The positioning of the circuit board carrying jig 1 can further achieve the position determination of the extracted circuit board, thereby assisting the alignment and installation of the circuit board and other components. After the extracted circuit board is moved to a target position, the locking assembly 12 of the circuit board carrying jig 1 changes from the locked state to the unlocked state, so as to achieve the unlocking of the circuit board carrying jig 1 and the extracted circuit board. The above is an example of the application scenario of the circuit board carrying jig 1 provided by an embodiment of the present application, and should not be understood as a limitation of the application scenario of the circuit board carrying jig 1 according to an embodiment of the present application.

[0091] The circuit board carrying jig 1 comprises a connecting plate 11 and a locking assembly 12, one end of a supporting piece 122 of the locking assembly 12 is fixedly connected with the connecting plate 11. In an alternative embodiment, the connecting plate 11 comprises a lifting plate part 111 and a connecting part 112, the lifting plate part 111 is used to be lifted to realize the lifting, moving, carrying and assembling of the circuit board; the connecting part 112 is connected with the supporting piece 122, so as to realize the connecting and fixing of the connecting plate 11 and the locking assembly 12. In an alternative embodiment, the lifting plate part 111 is located at the center position of the connecting plate 11, and the connecting part 112 is located at the edge position of the connecting plate 11.

[0092] The unlocking assembly 13 comprises a pressing plate 131, which is used to drive the pin rod 121 to move in the receiving cavity 122a in a direction away from the pressing plate 131. It can be understood that the pressing plate 131 can move or rotate relative to the connecting plate 11 to abut against one side of the pin rod 121 away from the ball 123, so as to drive the pin rod 121 to move in the receiving cavity 122a in a direction away from the pressing plate 131.

[0093] The traditional taking and placing of the circuit board is operated by a clamping device, and the clamping jaw part in the clamping device clamps multiple parts of the circuit board to move the circuit board. However, since the clamping force of the clamping jaw part needs to be adjusted and controlled, if the clamping force is too small, the circuit board cannot be clamped, or the circuit board falls off during the clamping and moving process, and if the clamping force is too large, the circuit board will be crushed and damaged.

[0094] In the present application, when the circuit board carrying jig 1 is connected with the circuit board, the pressing plate 131 moves or rotates relative to the connecting plate 11 to drive the pin rod 121 to move in the receiving cavity 122a in a direction away from the pressing plate 131, so that the ball 123 is accommodated in the receiving cavity 122a, thereby further making the locking assembly 12 in an unlocked state. The supporting piece 122 of the locking assembly in the unlocked state extends into the board hole of the circuit board from the side away from the connecting plate 11 until the through hole 122b is located on the side of the circuit board away from the connecting plate 11; the pin rod 121 moves in the receiving cavity 122a in a direction towards the pressing plate 131, so that the ball 123 partially protrudes out of the through hole 122b, the ball 123 abuts against the pin rod 121 and partially protrudes out of the through hole of the supporting piece 122, at this time, the part of the ball 123 protruding out of the through hole 122b abuts against the inner wall of the board hole of the circuit board, and the locking assembly 12 is in a locked state, thereby further realizing the connection between the circuit board carrying jig 1 and the circuit board.

[0095] It can be understood that when the circuit board carrying jig 1 in the connected state is separated from the circuit board, the pressing plate 131 moves or rotates relative to the connecting plate 11, and the pin rod 121 moves in the direction away from the pressing plate 131 in the receiving cavity 122a, so that the ball 123 is received in the receiving cavity 122a, and the locking assembly 12 enters the unlocked state from the locked state. The support 122 of the locking assembly in the unlocked state protrudes from the board hole of the circuit board on the side away from the connecting plate 11, so as to realize the separation of the circuit board carrying jig 1 and the circuit board.

[0096] In summary, the circuit board carrying jig 1 provided by the embodiment of the application includes a connecting plate 11, a locking assembly 12, and an unlocking assembly 13. The connecting plate 11 can realize the connection of the locking assembly 12 and the unlocking assembly 13, and can be used to lift to realize the movement of the circuit board carrying jig 1; the locking assembly 12 can be used to lock the circuit board carrying jig 1 and the circuit board, preventing the circuit board from falling off during transportation; and the unlocking assembly 13 can be used to unlock the circuit board carrying jig 1 and the circuit board. The locking assembly 12 includes a support 122, a pin rod 121, and a ball 123, and the unlocking assembly 13 includes a pressing plate 131. The support rod can be inserted into the board hole of the circuit board to realize the connection of the circuit board carrying jig 1 and the circuit board, the ball 123 and the pin rod 121 can cooperate to realize the locking and unlocking of the circuit board carrying jig 1 and the circuit board, and the pressing plate 131 makes the unlocking of the circuit board carrying jig 1 more convenient, without the need to unlock the balls 123 one by one, but only by pressing the pressing plate 131 to realize the unlocking of the circuit board carrying jig 1 and the circuit board. The circuit board carrying jig 1 provided by the embodiment of the application can realize the quick extraction and safe transportation of the circuit board.
