DETAILED DESCRIPTION

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] See also Figure 1-3 The present embodiment provides a semi-automatic soldering pin tool, comprising a carrier block 1, the carrier block 1 being provided with a limiting groove 101 for limiting a PCB board, and the carrier block 1 being provided with a plurality of insertion holes, all of which are located within the limiting groove 101. The plurality of insertion holes are matched one-to-one with the slots on the PCB board, and the pins are inserted into the corresponding insertion holes through the slots on the PCB board. The present solution provides the limiting groove 101, and the PCB board is placed within the limiting groove 101, thereby limiting the movement of the PCB board. This prevents the PCB board from sliding during the subsequent insertion of the pins into the PCB board by the operator, and during the process of the operator soldering the pins to the PCB board. This improves the soldering effect of the pins on the PCB board, and solves the problem that the existing pin soldering device is provided with a supporting area for placing the PCB board, which facilitates the operator to directly insert the pins into the PCB board and then solder the pins to the PCB board. Because the supporting area on the existing pin soldering device does not have a limiting structure, the PCB board still shakes when placed on the supporting area, thereby affecting the operator's soldering effect on the PCB board.

[0028] In order to further improve the limiting effect of the carrier block 1 on the PCB board, the present invention also includes a limiting component, which includes a pressing block 2, a connecting rod unit 3 and a sliding block 4. The interior of the carrier block 1 is hollow, and the carrier block 1 is provided with a lifting groove and a pressing groove. The lifting groove and the pressing groove are both located in the limiting groove 101. Specifically, the lifting groove is located on the bottom surface of the limiting groove 101, and the pressing groove is located on the side wall surface of the limiting groove 101. The lifting groove and the pressing groove are both interconnected with the interior of the carrier block 1. The sliding block 4 can be slidably arranged in the lifting groove, and the pressing block 2 can be extended. The shrinking part is set in the pressing groove, and the two ends of the connecting rod unit 3 are respectively connected to the sliding block 4 and the pressing block 2. The pressing block 2 can lock or release its abutting and fitting relationship with the PCB board. Through such a setting, when the PCB board is placed in the limiting groove 101, the PCB board will press the sliding block 4. Since the connecting rod unit 3 is respectively connected to the sliding block 4 and the pressing block 2, the sliding block 4 will drive the connecting rod unit 3 to control the pressing block 2 to extend out of the pressing groove, so that the pressing block 2 is fitted to the top surface of the PCB board, further limiting the movement of the PCB board. It is worth noting that the bottom surface of the pressing groove of this solution is flush with the surface of the PCB board, thereby ensuring that when the pressing block 2 is extended from the corresponding pressing groove, the pressing block 2 will fit the top surface of the PCB board, thereby limiting the vertical freedom of the PCB board.

[0029] Specifically, the connecting rod unit 3 of this scheme includes a bottom hinge rod 301, a vertical rod 302 and a side hinge rod 303. The vertical rod 302 can be vertically slidably arranged in the bearing block 1. The middle end of the bottom hinge rod 301 is hingedly arranged in the bearing block 1. The two ends of the bottom hinge rod 301 are respectively abutted against the bottom end of the sliding block 4 and the bottom end of the vertical rod 302. The two ends of the side hinge rod 303 are respectively hinged to the vertical rod 302 and the pressing block 2. The side hinge rod 303 can lock or release its horizontal setting state. It should be noted that, in the initial state, the side hinge rod 303 and the bottom hinge rod 301 are both tilted, and the bottom hinge rod 301 is close to the bottom hinge rod 301. The height of one end near the sliding block 4 is higher than the height of the bottom hinge rod 301 near the vertical rod 302; when the sliding block 4 is pressed by the PCB board, the sliding block 4 presses toward the bottom, causing the bottom hinge rod 301 to rotate, and it is transformed from an inclined state to a horizontal state, thereby enabling the bottom hinge rod 301 to lift the vertical rod 302, thereby causing the vertical rod 302 to move toward the top. Since the side wall hinge rod and the vertical rod 302 are hinged to each other, as the vertical rod 302 moves toward the top, the side wall hinge rod is transformed from an inclined state to a horizontal state, thereby enabling the pressing block 2 hinged to the side wall hinge rod to move in the direction of extending out of the pressing groove, so that the pressing block 2 extends out of the pressing groove.

[0030] In addition, the connection unit of the present scheme also includes a lifting spring 304, which is arranged in the supporting block 1. The two ends of the lifting spring 304 are respectively connected to the supporting block 1 and the end of the bottom hinged rod 301 close to the sliding block 4. The initial state of the bottom hinged rod 301 is tilted, and the end of the bottom hinged rod 301 close to the sliding block 4 is higher than the end of the bottom hinged rod 301 close to the vertical rod 302; by providing the lifting spring 304, when the PCB board is moved out of the supporting block 1, the lifting spring 304 can reset the bottom hinged rod 301, and then the entire connecting rod unit 3 can be reset, preparing for the next new PCB board welding.

[0031] In addition, in order to ensure that the pressing block 2 fits the PCB board after the PCB board is placed in the limiting groove 101, the pressing block 2 of this solution is tilted at the bottom of one end close to the PCB board, and the vertical height of the pressing block 2 gradually decreases along the sliding direction of the pressing block extending out of the pressing groove.

[0032] According to the above embodiment, it can be known that when the pressing block 2 is in contact with the top surface of the PCB board, the side hinged rod 303 is in a horizontal state; if you want to reset the connecting rod unit 3, you need to first push the pressing block 2 toward the inside of the pressing groove. However, since the side hinged rod 303 is in a horizontal state at this time, it is impossible to push the pressing block 2. In order to reset the connecting rod unit 3, the connecting rod unit 3 of this solution also includes a reset rod 305 and a reset spring 306. The vertical rod 302 is provided with a reset groove along its central axis. The reset rod 305 is slidably arranged in the reset groove, and the reset spring 306 is arranged in the reset groove. The two ends of the reset spring 306 are respectively connected to the vertical rod 302 and the reset The cam 305 is connected to the support block 1 by the lever 305, and the end of the side hinged lever 303 away from the pressing block 2 is hingedly arranged with one end of the reset lever 305. A connecting groove is provided on the side wall of the support block 1, and the central axis of the connecting groove is parallel to the central axis of the reset groove. The other end of the reset lever 305 passes through the connecting groove and extends out of the support block 1. Through such an arrangement, after the PCB board and the pin are welded, the operator presses the reset lever 305, and the reset lever 305 moves toward the bottom, so that the side hinged lever 303 is transformed from a horizontal state to an inclined state, thereby driving the pressing block 2 hinged to the side hinged lever 303 to move toward the inside of the pressing groove, so that the pressing block 2 releases its fitting relationship with the PCB board.

[0033] According to the above embodiment, the PCB board is taken out because the operator has completed the welding of the pins and the PCB board. In actual situations, the operator may insert an incorrect number of pins into the PCB board, which may cause the PCB board to be unable to be used normally. Based on this, in order to ensure that the number of pins inserted is correct, a plurality of limiting holes are opened at the bottom of the sliding block 4 of this scheme, and the plurality of limiting holes are arranged at equal intervals along the axial direction of the sliding block 4. In addition, when viewed from top to bottom, the positions of the plurality of limiting holes projected to the bottom surface do not overlap with each other. It also includes a plurality of limiting rods 5, and the plurality of limiting rods 5 are matched one-to-one with the plurality of limiting holes. The limiting rods 5 are horizontally slidably arranged in the carrier block 1, and one end of any limiting rod 5 can lock or release its matching relationship with the corresponding limiting hole; and the plurality of limiting rods 5 are matched one-to-one with the plurality of jacks, and the other end of any limiting rod 5 can be horizontally The pins are slidably disposed within corresponding receptacles, with the other end of the limiting rod 5 being able to lock or release them within the corresponding receptacles. Furthermore, it is worth noting that the pins also include a plurality of limiting springs 6, each corresponding to the plurality of limiting rods 5. The two ends of each limiting spring 6 are respectively connected to the corresponding limiting rod 5 and the interior of the support block 1. The limiting rod 5 is tilted at the top of one end near the receptacle, allowing the pins to lock or release their engagement with the corresponding limiting rod 5. With this arrangement, when a pin is inserted into a corresponding receptacle, the pin drives the corresponding limiting rod 5 to slide, releasing the corresponding limiting rod 5 from its engagement with the sliding block 4. Only when all pins are placed within their corresponding receptacles can the sliding block 4 slide; otherwise, the sliding block 4 will be unable to slide due to interference with the limiting rod 5. This arrangement ensures that all pins are inserted into their corresponding receptacles. Furthermore, the limiting springs 6 of this solution are used to ensure that after the soldered PCB is removed, the limiting rod 5 returns to its original position, re-establishing its engagement with the sliding block 4.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
