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.

[0020] Embodiment 1: As shown in the figure, a TYPE-C female socket defective tin connection repair device includes a frame 1 with a table top, a sliding frame 2 located above the table top of the frame 1 is slidably arranged on the frame 1, a heating rod 3 with its end facing the table top of the frame 1 and a scraper 4 located on one side of the heating rod 3 with its end facing the table top of the frame 1 is arranged on the sliding frame 2, an electric heating core is arranged in the heating rod 3, and a positioning plate 5 is arranged on the sliding frame 2 and is erected on one side of the sliding path of the sliding frame 2 and is parallel to the sliding path of the sliding frame 2. The spacing between the lower ends of the heating rod 3 and the scraper 4 and the table top of the frame 1 is adapted to the thickness of the circuit board. When the circuit board is placed on the table top of the frame 1, the lower ends of the heating rod 3 and the scraper 4 are against the circuit board.

[0021] Specifically, the sliding frame 2 is slidably arranged on the frame body 1: the frame body 1 is provided with two support rods 11 located above the table top of the frame body 1, the sliding frame 2 is penetrated by the support rods 11, and a sliding bearing is provided between the sliding frame 2 and the support rods 11 to ensure the stability and smoothness of the sliding frame 2 when sliding on the support rods 11, and a pushing handle 23 is fixedly connected to the sliding frame 2, so that the sliding frame 2 can be pushed to slide on the support rods 11 by holding the pushing handle 23.

[0022] Specifically, in order to enhance the stability of the circuit board when it is placed on the table top of the frame body 1, two clamps 6 perpendicular to the sliding path of the sliding frame 2 are arranged on the table top of the frame body 1, and two first adjustment grooves 12 parallel to the sliding path of the sliding frame 2 are opened on the table top of the frame body 1. The lower end of the clamp 6 is fixedly connected to a first adjustment rod 61 passing through the first adjustment groove 12, and the first adjustment nut 62 is screwed on the part of the first adjustment rod 61 passing through the first adjustment groove 12.

[0023] Specifically, in order to further enhance the stability of the circuit board when it is placed on the table top of the frame 1, a mounting portion 51 parallel to the table top of the frame 1 is formed at the upper end of the positioning plate 5, and a pressure plate 52 parallel to the table top of the frame 1 is provided on the mounting portion 51, and a first sliding rod 53 is fixedly connected to the pressure plate 52 and passes upward through the mounting portion 51, and the first sliding rod 53 is sleeved with a first spring 54 located between the mounting portion 51 and the pressure plate 52.

[0024] The TYPE-C female socket tinning defect repair process implemented by the TYPE-C female socket tinning defect repair device with the above structure: Step 1: Place the circuit board with the TYPE-C socket welded on it into the X-RAY inspection equipment for inspection to determine whether the TYPE-C socket has poor soldering. The X-RAY inspection equipment is an existing technology and will not be described in detail here. Step 2: Place the circuit board with poor tin connection of TYPE-C female seat screened in step 1 on the table of the frame 1 between the two clamping plates 6, and insert the TYPE-C female seat between the pressing plate 52 and the table of the frame 1 to press against the positioning plate 5, so that the pressing plate 52 is pressed against the TYPE-C female seat under the action of the first spring 54 to limit the TYPE-C female seat in the longitudinal direction, then loosen the first adjusting nut 62 and slide the clamping plate 6 in the first adjusting groove 12 through the first adjusting rod 61 to move toward the circuit board and press against the side end of the circuit board, and after tightening the first adjusting nut 62, the two clamping plates 6 are pressed against the two opposite side ends of the circuit board to limit the circuit board horizontally upward, so that the circuit board is fastened on the table of the frame 1 on one side of the sliding frame 2; Step three: energize the electric heating core so that it heats the heating rod 3 to a predetermined temperature, and then push the sliding frame 2 to slide on the support rod 11 toward the circuit board. When the sliding frame 2 slides from above the circuit board, the heating rod 3 slides with the sliding frame 2 so that the lower end of the heating rod 3 passes from one side of the TYPE-C mother seat and contacts the welding point between the pins of the TYPE-C mother seat and the circuit board, so that the heating rod 3 melts the tinned part of the welding point between the TYPE-C mother seat and the circuit board. While the heating rod 3 melts the tinned part, the scraper 4 moves with the sliding frame 2 and passes from one side of the TYPE-C mother seat, and the lower end of the scraper 4 contacts the welding point between the pins of the TYPE-C mother seat and the circuit board, so that the scraper 4 scrapes away the melted tinned part of the heating rod 3, thereby completing the repair of the poor tin connection at the welding point between the TYPE-C mother seat and the circuit board.

[0025] Step 4: Place the circuit board that has been repaired for poor soldering into the X-RAY inspection equipment for inspection to determine the poor soldering condition of the TYPE-C socket.

[0026] As a preferred solution of Embodiment 1, an adjustment portion 55 is formed at the lower end of the positioning plate 5 and is parallel to the table top of the frame body 1 and located below the table top of the frame body 1. The adjustment portion 55 is provided with two second adjustment grooves 56 that are perpendicular to the sliding path of the sliding frame 2. A second adjustment rod 13 is fixedly connected to the frame body 1 and passes downward through the second adjustment groove 56. A second adjustment nut 14 is screwed on the part of the second adjustment rod 13 that passes through the second adjustment groove 56.

[0027] In the above structure, after loosening the second adjusting nut 14, the second adjusting rod 13 slides in the second adjusting groove 56 to make the positioning plate 5 slide relative to the table surface of the frame body 1 in a direction perpendicular to the sliding path of the sliding frame 2, thereby adjusting the position of the positioning plate 5 relative to the sliding frame 2 and the heating rod 3 and the scraper 4 on the sliding frame 2, thereby adjusting the position of the TYPE-C mother seat relative to the heating rod 3 and the scraper 4 when it is on the positioning plate 5, and adjusting the position of the welding point between the TYPE-C mother seat and the circuit board relative to the heating plate and the scraper 4, to ensure that the lower ends of the heating rod 3 and the scraper 4 can accurately contact the welding point between the TYPE-C mother seat and the circuit board when the sliding frame 2 slides, so as to perform repair operations on poor tin connection.

[0028] As a preferred solution of Embodiment 1, a swing plate 7 is provided on the sliding frame 2, and the heating rod 3 is fixedly provided on the swing plate 7 and is inclined on a table surface of the frame body 1. A mounting sleeve 71 with closed ends is formed on the swing plate 7, and the heating rod 3 is inserted into the mounting sleeve 71 and a limiting portion 31 located in the mounting sleeve 71 is formed on the side surface of the heating rod 3, and a second spring 72 located between the limiting portion 31 and the upper end port of the mounting sleeve 71 is provided in the mounting sleeve 71.

[0029] In the above structure, the inclined setting of the heating rod 3 enables its lower end to better contact with the welding point between the TYPE-C mother seat and the circuit board, and under the cooperation of the second spring 72 and the limiting portion 31, the lower end of the heating rod 3 has a tendency to slide toward the circuit board, ensuring that the lower end of the heating rod 3 maintains contact with the welding point between the TYPE-C mother seat and the circuit board when the sliding frame 2 passes from one side of the TYPE-C mother seat, thereby ensuring that the tinning part at the lower end of the heating rod 3 is melted to achieve the repair of poor tinning.

[0030] As a preferred solution of Example 1, the end of the swing plate 7 close to the positioning plate 5 is rotatably connected to the sliding frame 2, and a circular arc-shaped fastening plate 21 is formed on the sliding frame 2 and located on the side of the end of the swing plate 7 away from the positioning plate 5. A swing groove 22 is provided on the fastening plate 21, and the end of the swing plate 7 away from the positioning plate 5 is fixedly connected with a swing rod 73 passing through the swing groove 22, and a swing handle 74 tightly pressed against the fastening plate 21 is screwed on the part of the swing rod 73 passing through the swing groove 22.

[0031] In the above structure, after loosening the swing handle 74, the swing plate 7 can be driven to swing on the sliding frame 2 by driving the swing rod 73 to swing in the swing groove 22, thereby driving the heating rod 3 to swing on the sliding frame 2. Its function is that after the scraper 4 moves with the sliding plate to scrape off the tinned part melted by the heating rod 3 for the first time, the heating rod 3 is swung to make its lower end leave the position of contact with the circuit board. When driving the sliding frame 2 to reset, the scraper 4 scrapes the welding part between the TYPE-C mother seat and the circuit board for the second time to ensure that there is no tinned part When the scraper 4 scrapes the tinned part for the second time, since the heating rod 3 has left the contact position with the circuit board, the heating plate will not cause secondary melting of the welding point between the TYPE-C mother seat and the circuit board when the sliding frame 2 is reset, thereby affecting the welding of the TYPE-C mother seat and the circuit board. In addition, the spacing between the lower end of the heating rod 3 and the table top of the frame 1 can be adjusted by swinging the heating rod 3, and the position of the positioning plate 5 can be adjusted to adapt to circuit boards of different thicknesses, thereby having better applicability.

[0032] As a preferred solution of Embodiment 1, the scraper 4 is made of a flexible material and has an X-shaped cross-section. The scraper 4 is perpendicular to the table top of the frame body 1 and the opening of the scraper 4 faces the sliding path of the sliding frame 2. A T-shaped connecting portion 41 is formed on the upper end of the scraper 4. A connecting groove 24 matching the connecting portion 41 is provided on the sliding frame 2. The connecting portion 41 is inserted into the connecting groove 24. A cover plate 25 that limits the connecting portion 41 in the connecting groove 24 is fixedly connected to the notch of the connecting groove 24 by bolts, thereby realizing a fixed connection between the scraper 4 and the sliding frame 2. The above-mentioned connection method between the scraper 4 and the sliding frame 2 enables the scraper 4 to be easily disassembled and assembled, and it is convenient to replace or maintain the scraper 4.

[0033] In the above structure, the flexible scraper 4 can better maintain contact with the circuit board when scraping the melted tin-connecting part to ensure that the melted tin-connecting part is scraped cleanly, and the scraper 4 with an X-shaped cross-section has a gathering effect on the melted tin-connecting part when scraping the tin-connecting part for the first and second time, preventing the melted solder from flowing freely when scraping the tin-connecting part and affecting other welding components on the circuit board.

[0034] It can be seen that the TYPE-C female socket defective tin connection repair device in the above embodiment can accurately and quickly remove the tin connection part of the welding point between the TYPE-C female socket and the circuit board through the cooperation of the positioning plate 5, the heating rod 3 and the scraper 4, thereby reducing the maintenance time and the difficulty of maintenance, and can meet the customer's requirements of low cost, saving labor hours and fast settlement of orders.

[0035] Embodiment 2: On the basis of Example 1, the sliding frame 2 is provided with a paste coating component 8 located on the other side of the heating plate relative to the scraper 4, and the paste coating component 8 includes a paste storage cylinder 81, a transfer wheel 82 and a brush wheel 83. The paste storage cylinder 81 is fixedly arranged on the sliding frame 2, and the transfer wheel 82 is rotatably arranged on the sliding frame 2 and abuts against the lower end opening of the paste storage cylinder 81. The brush wheel 83 is rotatably arranged on the sliding frame 2 and is located below the transfer wheel 82 and abuts against the transfer wheel 82. The transfer wheel 82 and the brush wheel 83 are transmission-connected with a motor 84 arranged on the sliding frame 2, wherein the transfer wheel 82 and the brush wheel 83 are transmission-connected by the cooperation of a synchronous wheel and a synchronous belt, and the transfer wheel 82 and the output shaft of the motor 84 are transmission-connected by the cooperation of a synchronous wheel and a synchronous belt.

[0036] In the above structure, when the heating rod 3 and the scraper 4 are driven by the sliding frame 2 to move toward the circuit board in the above step 3, the paste coating assembly 8 moves toward the circuit board with the sliding frame 2, so that the brush wheel 83 contacts the circuit board before the heating rod 3, and when the brush wheel 83 passes through one side of the TYPE-C mother seat, the motor 84 drives the transfer wheel 82 to rotate (the start of the motor 84 is achieved by the sensor provided on the sliding frame 2 detecting the TYPE-C mother seat when the sliding frame 2 moves), and the transfer wheel 82 drives the brush wheel 83 to rotate, and the rotating transfer wheel 8 2 The soldering paste placed in the paste storage tube 81 is adhered to the peripheral side surface of the transfer wheel 82 through the lower end opening of the paste storage tube 81, and the brush wheel 83 that rotates and contacts the transfer wheel 82 adheres the soldering paste adhered to the peripheral side surface of the transfer wheel 82 to the bristles of the brush wheel 83. When the brush wheel 83 passes from one side of the TYPE-C mother seat with the sliding frame 2, the soldering paste is applied to the welding point between the TYPE-C mother seat and the circuit board. Through the effect of the soldering paste, the subsequent heating rod 3 melts the tinned part faster and more thoroughly, ensuring the effect of repairing poor tinning.

[0037] As a preferred solution of Example 2, a sealing cover 85 is screwed on the upper opening of the paste storage tube 81, and a second sliding rod 86 is passed through the sealing cover 85, and the lower end of the second sliding rod 86 extends into the paste storage tube 81, and the lower end of the second sliding rod 86 is fixedly connected to a paste pressing plate 87 matching the inner diameter of the paste storage tube 81, and the second sliding rod 86 is sleeved with a third spring 88 located between the paste pressing plate 87 and the sealing cover 85.

[0038] In the above structure, the paste pressing plate 87, under the action of the third spring 88, presses against the flux paste placed in the paste storage tube 81 to squeeze the flux paste, so that the flux paste in the paste storage tube 81 tends to move toward the lower end opening of the paste storage tube 81, thereby ensuring that the flux paste in the paste storage tube 81 maintains contact with the transfer wheel 82 through the lower end opening of the paste storage tube 81, and is transferred to the brush wheel 83 under the action of the transfer wheel 82 for applying the flux paste.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
