The USB Type-C interface (called Type-C for short) is a hardware interface form of a Universal Serial Bus (USB), and the largest characteristic of the Type-C double-sided pluggable interface is to support double-sided insertion of the USB interface. The Type-C Type connector in the current industry is designed in double rows of pins, the SMT production process of the Type-C Type connector needs to be designed by straddling, the Type-C Type connector is assembled on a bonding pad of a PCB in advance in a crimping mode before welding, and meanwhile the Type-C Type connector is accurately aligned with X & Y directions of a TOP and BOT two-sided Pin bonding pad of the PCB, and a certain levelness is kept with the PCB in the Z direction. However, the conventional SMT mounting process with straight up and down cannot be used. However, the use of manual hand swing has the problems of low efficiency and poor welding yield due to insufficient alignment accuracy.

Referring to fig. 1 to 13, in an implementation manner, the batch crimping fixture for the straddle Type double-sided pin Type-C connector may include: the workbench 1 comprises a boss 13 and thrust components 11 arranged on two sides of the boss; the carrier 2 is detachably arranged on the boss 13, and the carrier 2 is used for bearing the PCB 5; the capping mechanism 3 includes a press block 33 movable relative to the boss for applying a certain pressure to the PCB 5. According to the embodiment, the carrier is used for simultaneously forming effective support for the PCB 5 and the Type-C element 4, so that the PCB 5 and the Type-C element 4 are conveniently centered; the thrust components 11 on two sides of the boss 13 can push multiple groups of Type-C elements, so that batch plugging operation of multiple groups of PCB boards and Type-C elements can be realized; the gland mechanism 3 is used for fixing the PCB 5 in the vertical direction, so that the displacement in the vertical direction is prevented when the thrust component acts.

In one possible embodiment, as shown in fig. 2 and 3, the thrust assemblies 11 are symmetrically arranged on both sides of the boss 13 with the boss 13 as a center. The thrust assembly 11 may include a first moving mechanism and a push head disposed on the first moving mechanism, and the push head may be close to or far from the boss 13 under the action of the first moving mechanism. The first moving mechanism can move under the operation of a technician, but in the operation process, the force of the pushing head pair needs to be ensured to be kept in a specific direction, for example, when the pushing head pair is pushed horizontally, the force of the pushing head needs to be ensured not to deviate from the horizontal direction, otherwise, the corresponding deviation is possibly caused by the deviation of the pushing force of the pushing head, so that the plugging of the PCB and the Type-C element is also caused.

To solve the above-mentioned problem, as shown in fig. 2, in one possible embodiment, the first moving mechanism may include a first guide rail 111 and a first slider 112 slidably engaged therewith. Specifically, the first rail 111 is fixed, and the first slider 112 is used as an output end, and displacement is realized on the first rail 111; it will be appreciated that it is also possible to fix the first slider 112 and to displace the first rail 111 as output on the first slider. The first rail 111 and the first slider 112 may be fixed to the table top 10 as separate components; alternatively, the table top and the first rail 111 (or the first slider 112) may be designed as a single structure, for example, the first rail 111 (or the first slider 112) may be directly machined on the table top 10, which is not limited herein. The cooperation of the first guide rail 111 and the first sliding block 112 can realize stable movement, improve centering precision, ensure that the acting force of thrust is on a preset straight line and avoid deviation in the plugging process.

Because the grafting of PCB board and Type-C component needs certain precision, when manual operation thrust subassembly 11, if the strength is too little or the displacement can cause the grafting not put in place, and the too big or too big can cause the grafting too deep even cause the damage of PCB board and Type-C component of displacement.

To solve the above-mentioned problem, in one possible embodiment, as shown in fig. 3, the first driving mechanism 12 is also symmetrically provided. The first driving structures 12 are respectively connected with the output ends of the first moving mechanisms, can replace manual operation, apply uniform force to the output ends of the first moving mechanisms, and realize preset displacement. The first driving mechanism may be a transmission mechanism comprising: the electric push rod, the electric cylinder, the pneumatic cylinder, the hydraulic cylinder, the linear motor and the like can be selected and matched according to production requirements. Taking the first driving mechanism 12 as an example of selecting a hydraulic cylinder, the first cylinder 121 may be fixed on the first guide rail 111, the first piston rod 122 may be fixed on the first slider 112, and the first slider 112 may be close to or far from the boss 13 along with the expansion and contraction of the first piston rod 122 in the first cylinder 121. Therefore, the applied thrust is more stable, and the feeding speed and the stroke are easier to control accurately.

To reduce vibration of the thrust assembly when pushing the Type-C element, to provide a buffer during pushing and to ensure a more uniform force of each pusher, in one possible embodiment, the pusher includes a base 113 and a nose 114, as shown in fig. 4. The base 113 is provided at the output end of the first moving mechanism, and here, the first guide 111 is fixed, and the first slider 112 is described as an output end. The base 113 is fixedly connected to the first slider 112 and is displaceable on the first guide rail 111 with the first slider 112. The base 113 and the first slider 112 are detachably connected, so that bases with different sizes and different numbers can be arranged on the first slider 112 according to actual production needs, that is, in an actual application scene, the types, specifications, numbers and positions of the push heads can be increased or decreased according to production needs, and the number is not limited to that shown in the drawings, so that the application range of the workbench can be improved. The base 113 is of a hollow structure and comprises a cavity, the root of the raised head 114 is positioned in the cavity, and the head of the raised head 114 extends outwards of the cavity. A first resilient element 115 is provided between the root and the base 113, i.e. the root of the nose and the first resilient element 115 are both substantially located in the mould cavity. The first elastic member 115 may be a spring, a cushion, or the like.

In one implementation manner, to prevent the root of the nose 114 from coming out of the cavity, the first elastic member 115 may be fixedly connected to the root of the nose 114 and the inner wall of the cavity, respectively, or the nose 114 may be configured as a table structure, where the area of the cross section of the root of the nose 114 is larger than the area of the opening of the cavity, and the area of the opening of the cavity is larger than the area of the head of the nose, or a limiting portion may be disposed at the root to prevent the nose 114 from ejecting from the cavity.

In one implementation, as shown in fig. 4, the first elastic member 115 may be a foolproof spring, and the force required for crimping each Type-C element to the assembly required position is calculated by using a thrust test, so that the force and the moving stroke of the pushing head calculate the required spring coefficient, and a corresponding spring with a suitable model is selected, the elastic force of which is consistent with the required thrust force of the crimping connector, so as to ensure that each element is not affected by the interference of the tolerance, and can be assembled in place according to the design stroke.

In one implementation, as shown in fig. 5 and 6, the carrier 2 includes a base plate 20, and thrust plates 21 disposed on both sides of the base plate 20. A plurality of clamping grooves 22 are formed between the thrust plates 21. The number of thrust plates 21 may be set according to actual production requirements and is not limited to the number shown in the drawings. When the straddling Type double-sided pin Type-C connector is in press-connection, the clamping groove 22 is used for bearing the Type-C element 4, and the opening of the clamping groove 22 faces the PCB 5. The thrust plate 21 can limit the Type-C element 4 to ensure that it is displaced on a prescribed path, preventing it from shifting the prescribed path. In this way, when the pushing component applies pushing force to the Type-C element 4, the Type-C element 4 is limited by the pushing plate 21 in the clamping groove 22, so that the pin plate 51 of the PCB board 5 can be accurately aligned with and inserted into the Type-C element.

In one implementation manner, the carrier 2 includes the hollowed-out portion 25, and the hollowed-out portion 25 is used for only supporting the substrate 52 when the PCB board is placed on the carrier, so that the pin board 51 is located in the hollowed-out portion and is in a suspended state, and therefore the pin board 51 of the PCB board 5 and the Type-C element are not affected by the force in the vertical direction of the carrier in the plugging process.

In order to further improve the working accuracy, ensure that the thrust component is more accurate when applying the thrust to the Type-C element 5, in one possible embodiment, as shown in fig. 2, 5 and 7, the boss 13 and the carrier 2 are respectively provided with a positioning portion that is mutually matched. Specifically, the positioning portion may include a first positioning protrusion 131 disposed on the boss, and a first positioning hole 23 disposed on the carrier, where the first positioning protrusion 131 and the first positioning hole 23 are matched with each other, so as to perform positioning when the carrier 2 is placed on the boss 13. The first positioning protrusion 131 and the first positioning hole 23 may be provided in one group or in a plurality of groups, which is not limited in the present invention.

It will be appreciated that the positioning portions are not limited to the first positioning projections 131 and the first positioning holes 23 described above. In one implementation manner, the carrier 2 may be provided with a placement portion for carrying the PCB 5, where the placement portion may be concavely disposed on the carrier, and the shape of the placement portion exactly matches with the shape of the base 52, so that the base 52 may be exactly placed in the concaved placement portion, and thus, positioning between the PCB 5 and the concaved placement portion may be completed through cooperation.

In order to further improve the operation accuracy, in one possible embodiment, as shown in fig. 5 to 6, the PCB 5 may be processed with a second positioning hole 50, and the carrier 2 may be provided with a second positioning protrusion 24 that is matched with the second positioning hole 50, so that the PCB 5 may be precisely placed at a predetermined position and displaced in the plane direction of the PCB during the press-connection process.

In one possible embodiment, the capping mechanism 3 comprises a press block 33 that is movable relative to the boss 13. In actual production, the pressing block 33 can be pressed on the base body 52 of the PCB 5 by manually operating the pressing cover mechanism 3 so as to apply pressure to the PCB in the direction perpendicular to the plane of the PCB, fix the PCB and prevent the PCB from being displaced perpendicular to the PCB surface under the thrust action of the thrust component. However, during manual operation, the attention and physical strength of the personnel often affect the processing efficiency and the processing quality.

In order to solve the above-described problem, in one possible embodiment, as shown in fig. 8, the capping mechanism 3 includes a second moving mechanism. The pressing block 33 is fixed on the output end of the second moving mechanism. The second moving mechanism may include a second guide rail 35, a second slider 30, and a pressing block 33 fixed to the second slider 30. The cooperation of the second guide rail 35 and the second slider 30 can realize that the moving track of the pressing block 33 cannot deviate in the pressing process, and the direction of the pressing force of the pressing block 33 is kept perpendicular to the plane of the PCB. The second guide rail 35 can be fixed on the upright post 36, and the upright post 36 can be arranged beside the workbench according to the requirement, so that the pressing block 33 can be accurately pressed on the PCB. In one implementation manner, a second driving mechanism may be further provided, where the second driving mechanism may be selected from the following transmission mechanisms, including: the electric push rod, the electric cylinder, the pneumatic cylinder, the hydraulic cylinder, the linear motor and the like can be selected and matched according to production requirements. Taking a hydraulic cylinder as an example, the second driving mechanism may include a second cylinder 38, a second piston rod 39, where the second piston rod 39 is fixed on the second slider 30, and the second cylinder 38 may be fixed on the second guide rail 35, so that the second slider 30 may displace on the second guide rail 35 along with the expansion and contraction of the second piston rod 39 in the second cylinder 38, so as to drive the pressing block 33 to press on the PCB board and apply pressure to the PCB board, or be far away from the PCB board.

In one possible embodiment, as shown in fig. 9, the capping mechanism 3 may include a second drive mechanism and a press 33. The second driving mechanism may be an electric push rod, an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, a linear motor, or the like, and taking the second driving mechanism as an example, the hydraulic cylinder is selected as the second driving mechanism, the pressing block 33 may be fixed on the second piston rod 39, the second cylinder 38 is fixed on the bracket 37, and the movement direction of the second piston rod 39 is perpendicular to the plane of the PCB board. In this way, the pressing block 33 can be driven by the second piston rod 39 to press on the PCB board and apply pressure to the PCB board, or be far away from the PCB board. The bracket 37 can be fixed on the upright 36, and the upright 36 can be arranged beside the workbench 1; or the bracket 37 may be provided directly above the table 1.

The second elastic member 32 is disposed in the housing 31, one end of the second elastic member 32 is connected to the inner wall of the housing, and the other end is connected to one end of the pressing block 33 away from the boss.

In one embodiment, to prevent the pressing block 33 from being separated from the housing 31, the second elastic member 32 may be fixedly connected to the pressing block 33 and the inner wall of the housing 31, respectively, or the pressing block 33 may be configured as a table structure, wherein the area of the cross section of the portion located in the housing 31 is larger than the area of the opening of the housing 31, and the area of the opening of the housing is larger than the area of the cross section of the portion of the pressing block 33 extending out of the housing, or a limit portion 331 may be provided at the portion of the pressing block 33 located in the housing to prevent the pressing block 33 from being separated from the housing.

The length of the pressing block 33 is greater than the length of the PCB 5, that is, the distance between the positioning mechanisms 332 at two sides of the pressing block 33 is greater than the length of the PCB 5, so that the pressing block 33 can be completely attached to the PCB, and the positioning plates 332 can abut against two sides of the PCB 5. The length of the positioning plate 332 extending out of the working surface (i.e. the surface facing the PCB) of the pressing block 33 is equal to the thickness of the PCB. The positioning plate 332 may be made of a material with magnetic force, and the carrier 2 may be made of a material with magnetic force, or a magnetic part may be disposed at a position contacting with the positioning plate 332, so that the carrier may just be attracted to the positioning plate 332, to increase the pressure of the pressing block 33 on the PCB, and to enhance the fixing effect.
