[0002] SMT (Surface Mount Technology) is a precision manufacturing technology for mounting various chip-type electronic components onto a printed circuit board or mounting bare chips onto a packaging substrate. Due to the advantages of high efficiency, high qualification rate, and low cost of the SMT (Surface Mount Technology) chip mounting technology, this technology is widely used in the production and manufacturing process of electronic products.

[0003] The USB Type-C interface (abbreviated as Type-C) is a hardware interface form of the Universal Serial Bus (USB).

[0011] Further, the carrier includes a substrate, and a plurality of thrust plates oppositely disposed on both sides of the substrate. The plurality of thrust plates enclose a plurality of card slots.

[0012] Further, the capping mechanism includes a second moving mechanism, and the pressing block is fixed to the output end of the second moving mechanism.

[0013] Further, the output end of the second moving mechanism includes a housing. A second elastic member is disposed in the housing.

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0034] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0035] Unless otherwise clearly defined and limited, the terms "installation", "connection", "attachment", and "fixation" shall be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. It can be the internal communication between two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may include direct contact between the first feature and the second feature, or may include the situation where the first feature and the second feature are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath", and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature.

[0037] The USB Type-C interface (abbreviated as Type-C) is a hardware interface form of the Universal Serial Bus (USB). The biggest feature of the Type-C double-sided pluggable interface is that it supports double-sided insertion of the USB interface. Currently, all connectors of the Type-C type in the industry are designed with double-row pins. Its SMT production process requires a straddle design. Before soldering, it needs to be assembled on the pads of the PCB by crimping in advance, and at the same time, it needs to be accurately aligned with the pad pins on both the TOP and BOT sides of the PCB in the X and Y directions and maintain a certain levelness with the PCB in the Z direction. However, the above process cannot use the conventional up-and-down SMT mounting process. And using manual placement has problems such as low efficiency and poor soldering yield due to insufficient alignment accuracy.

[0038] Please also refer to Figures 1 to 13In an achievable implementation, a straddle-type double-sided pin Type-C connector batch crimping jig may include: a workbench 1, the workbench includes a boss 13, and thrust assemblies 11 arranged on both sides of the boss; a carrier 2, the carrier 2 is detachably arranged on the boss 13, and the carrier 2 is used to carry a PCB board 5; a pressing mechanism 3, including a pressing block 33 that can move relative to the boss, and the pressing block is used to apply a certain pressure to the PCB board 5. In this embodiment, the carrier is used to form an effective support for the PCB board 5 and the Type-C component 4 at the same time, which is convenient for the centering of the PCB board 5 and the Type-C component 4; the thrust assemblies 11 on both sides of the boss 13 can push multiple groups of Type-C components, so as to realize the batch plug-in operation of multiple groups of PCB boards and Type-C components; the pressing mechanism 3 is used to fix the PCB board 5 in the vertical direction to prevent it from being displaced in the vertical direction when the thrust assembly acts.

[0039] In one possible implementation, Figure 2 and Figure 3 As shown, the thrust assembly 11 is symmetrically arranged on both sides of the boss 13 with the boss 13 as the center. The thrust assembly 11 may include a first moving mechanism and a push head arranged on the first moving mechanism, and the push head may approach or move away from the boss 13 under the action of the first moving mechanism. The first moving mechanism may be moved under the operation of a technician, but during the operation, it is necessary to ensure that the force of the push head is maintained in a specific direction. For example, when pushing horizontally, it is necessary to ensure that the force of the push head cannot deviate from the horizontal direction, otherwise the insertion of the PCB board and the Type-C component may also be deviated accordingly due to the deviation of the push head thrust.

[0040] To solve the above problems, Figure 2 As shown, in an achievable embodiment, the first moving mechanism may include a first guide rail 111 and a first slider 112 that slides with the first guide rail 111. Specifically, the first guide rail 111 is fixed, and the first slider 112 is used as an output end to achieve displacement on the first guide rail 111; it is understandable that the first slider 112 may also be fixed, and the first guide rail 111 is used as an output end to achieve displacement on the first slider. The first guide rail 111 and the first slider 112 may be fixed on the table 10 as separate components; or the table and the first guide rail 111 (or the first slider 112) may be designed as an integrated structure, for example, the first guide rail 111 (or the first slider 112) may be directly machined on the table 10, and the present invention is not limited thereto. The cooperation between the first guide rail 111 and the first slider 112 may achieve smooth movement, improve centering accuracy, ensure that the thrust force is on a predetermined straight line, and avoid displacement during the plug-in process.

[0041] Since the insertion of the PCB board and the Type-C component requires a certain degree of precision, when manually operating the thrust assembly 11, if the force is too small or the displacement is insufficient, the insertion may not be in place. If the force is too large or the displacement is excessive, the insertion may be too deep, even causing damage to the PCB board and the Type-C component.

[0042] To solve the above problems, in one feasible implementation, as Figure 3 shown, a first driving mechanism 12 is also symmetrically provided. The first driving structure 12 is respectively connected to the output end of the first moving mechanism, which can replace manual operation, apply a uniform force to the output end of the first moving mechanism, and achieve a predetermined displacement. The first driving mechanism can select the following transmission mechanisms, including: electric push rods, electric cylinders, pneumatic cylinders, hydraulic cylinders, linear motors, etc., which can be specifically selected according to production needs. Taking the first driving mechanism 12 selecting a hydraulic cylinder as an example, the first cylinder barrel 121 can be fixed on the first guide rail 111, the first piston rod 122 can be fixed on the first slider 112, and the first slider 112 can then approach or move away from the boss 13 along with the telescopic movement of the first piston rod 122 in the first cylinder barrel 121. In this way, the applied thrust can be made more stable, and the feed speed and stroke are easier to accurately control.

[0043] To reduce the vibration of the thrust assembly when pushing the Type-C component, provide a buffer during the pushing process, and ensure that the forces of each push head are more uniform, in one feasible implementation, as Figure 4 shown, the push head includes a base 113 and a convex head 114. The base 113 is arranged at the output end of the first moving mechanism. Here, taking the first guide rail 111 being fixed and the first slider 112 as the output end as an example for illustration. The base 113 is fixedly connected to the first slider 112 and can move along with the first slider 112 on the first guide rail 111. The base 113 and the first slider 112 are detachably connected. Therefore, bases of different sizes and numbers can be set on the first slider 112 according to actual production needs. That is, in actual application scenarios, the types, specifications, numbers, and positions of the push heads can all be increased or decreased according to production needs, and are not limited to the quantities shown in the drawings. Thus, the applicable range of the workbench can also be improved. The base 113 is a hollow structure, including a cavity. The root of the convex head 114 is located in the cavity, and the head of the convex head 114 extends outward beyond the cavity. A first elastic member 115 is arranged between the root and the base 113. That is to say, the root of the convex head and the first elastic member 115 are actually both located in the cavity. The first elastic member 115 can be a spring, a shock pad, etc.

[0044] In an implementable embodiment, to prevent the root of the convex head 114 from disengaging from the cavity, the first elastic member 115 can be fixedly connected to the root of the convex head 114 and the inner wall of the cavity respectively, or the convex head 114 can be configured as a frustum structure. Wherein, the cross-sectional area of the root of the convex head 114 is greater than the area of the opening of the cavity, and the area of the opening of the cavity is greater than the area of the head of the convex head. Alternatively, a limiting portion can also be provided at the root to prevent the convex head 114 from popping out of the cavity.

[0045] In an implementable embodiment, as Figure 4 shown, the first elastic member 115 can be an anti-fooling spring. By using a thrust test to calculate the force required for each Type-C component to be crimped to the assembly required position, the required spring coefficient is calculated from this force and the push head movement stroke, and a corresponding spring of a suitable model is selected. Its elastic force is consistent with the required thrust of the crimping connector, ensuring that each component is not interfered by cumulative tolerances and can be assembled in place according to the designed stroke.

[0046] In an implementable embodiment, as Figure 5 and Figure 6 shown, the carrier 2 includes a substrate 20 and thrust plates 21 provided on both sides of the substrate 20. A plurality of card slots 22 are defined between the thrust plates 21. The number of thrust plates 21 can be set according to actual production needs and is not limited to the number shown in the drawings. When performing the crimping operation on the double-sided pin Type-C connector with straddle type, the card slots 22 are used to carry the Type-C components 4, and the openings of the card slots 22 face the PCB board 5. The thrust plates 21 can limit the Type-C components 4 to ensure their displacement along the specified route and prevent them from deviating from the predetermined route. In this way, when the thrust assembly applies a thrust to the Type-C components 4, the Type-C components 4 are limited by the thrust plates 21 in the card slots 22, so that they can be accurately aligned with the pin board 51 of the PCB board 5 and inserted into the Type-C components.

[0047] In an implementable embodiment, the carrier 2 includes a hollow portion 25. The hollow portion 25 is used to only support the substrate 52 when the PCB board is placed on the carrier, while the pin board 51 is located in the hollow portion and is in a suspended state. In this way, the pin board 51 of the PCB board 5 will not be affected by the force in the vertical direction of the carrier during the insertion process with the Type-C components.

[0048] To further improve the operation accuracy and ensure that the thrust assembly is more precise when applying a thrust to the Type-C components 5, in an implementable embodiment, as Figure 2 、 Figure 5 、 Figure 7As shown, the boss 13 and the carrier 2 are respectively provided with positioning parts that cooperate with each other. Specifically, the positioning parts may include a first positioning bump 131 provided on the boss and a first positioning hole 23 provided on the carrier. The first positioning bump 131 and the first positioning hole 23 cooperate with each other to perform positioning when the carrier 2 is placed on the boss 13. The first positioning bump 131 and the first positioning hole 23 may be provided in one group or multiple groups, and the present invention does not limit this.

[0049] It can be understood that the positioning parts are not limited to the above-mentioned first positioning bump 131 and first positioning hole 23. In a feasible implementation manner, the carrier 2 may be provided with a placement part for carrying the PCB board 5. The placement part may be recessed on the carrier, and its shape exactly matches the shape of the base 52, so that the base 52 can be exactly placed in the recessed placement part. Thus, the PCB board 5 and the recessed placement part can complete positioning through cooperation.

[0050] In order to further improve the operation accuracy, in a feasible implementation manner, as Figures 5 to 6 shown, the PCB board 5 may be processed with a second positioning hole 50, and the carrier 2 may be provided with a second positioning bump 24 that cooperates with the second positioning hole 50, so that the PCB board 5 can be accurately placed at a predetermined position and prevent it from generating displacement in the plane direction of the PCB board during the crimping process.

[0051] In a feasible implementation manner, the capping mechanism 3 includes a pressing block 33 that can move relative to the boss 13. In actual production, the capping mechanism 3 can be manually operated to press the pressing block 33 on the base 52 of the PCB board 5, so as to apply pressure to the PCB board in the direction perpendicular to the plane of the PCB board to fix it and prevent it from generating displacement perpendicular to the plane of the PCB board under the thrust of the thrust component. However, during manual operation, the attention and physical strength of the personnel often affect the processing efficiency and processing quality.

[0052] To solve the above problems, in a feasible implementation manner, as Figure 8As shown, the gland mechanism 3 includes a second moving mechanism. The pressing block 33 is fixed to the output end of the second moving mechanism. The second moving mechanism may include a second guide rail 35 and a second slider 30, and the pressing block 33 is fixed to the second slider 30. The cooperation between the second guide rail 35 and the second slider 30 can ensure that the running track of the pressing block 33 does not deviate during the pressing process, and ensure that the direction of the pressure of the pressing block 33 is perpendicular to the plane of the PCB board. The second guide rail 35 can be fixed to the column 36, and the column 36 can be arranged beside the workbench as required to ensure that the pressing block 33 can accurately press on the PCB board. In an implementable embodiment, a second driving mechanism may also be provided. The second driving structure can select the following transmission mechanisms, including: electric push rod, electric cylinder, pneumatic cylinder, hydraulic cylinder, linear motor, etc., and can be specifically selected according to production needs. Taking the hydraulic cylinder as an example, the second driving mechanism may include a second cylinder barrel 38 and a second piston rod 39. The second piston rod 39 is fixed to the second slider 30, and the second cylinder barrel 38 can be fixed to the second guide rail 35. In this way, the second slider 30 can move on the second guide rail 35 with the telescopic movement of the second piston rod 39 in the second cylinder barrel 38, and then drive the pressing block 33 to press on the PCB board and apply pressure to it, or move away from the PCB board.

[0053] In an implementable embodiment, as Figure 9 shown, the gland mechanism 3 may include a second driving mechanism and a pressing block 33. The second driving mechanism can select an electric push rod, an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc. Taking the second driving mechanism selecting a hydraulic cylinder as an example, the pressing block 33 can be fixed to the second piston rod 39, the second cylinder barrel 38 is fixed to the bracket 37, and the moving 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 it, or move away from the PCB board. The bracket 37 can be fixed to the column 36, and the column 36 can be arranged beside the workbench 1; or the bracket 37 can also be directly arranged above the workbench 1.

[0054] The PCB board is currently developing towards high density, lightweight, and thinness. Therefore, in an implementable embodiment, to prevent damage to the PCB board during the process of applying pressure by the gland mechanism, a housing 31 can be provided, and the pressing head 33 is arranged inside the housing 31. In an implementable embodiment, the housing 31 is fixed to the output end of the second moving mechanism. For example, in Figure 8 it, the housing 31 is fixed to the second slider 30; or in another implementable embodiment, the housing 31 can also be fixed to the second piston rod 39 as Figure 9 shown. A second elastic member 32 is arranged inside 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 the end of the pressing block 33 away from the boss.

[0055] In an implementable embodiment, to prevent the pressing block 33 from disengaging from the housing 31, the second elastic member 32 can be fixedly connected to the pressing block 33 and the inner wall of the housing 31 respectively, or the pressing block 33 can be configured as a frustum structure, wherein the cross-sectional area of the part located inside 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 cross-sectional area of the part of the pressing block 33 protruding outside the housing, or a limiting portion 331 can also be provided on the part of the pressing block 33 located inside the housing to prevent the pressing block 33 from disengaging from the housing.

[0056] In an implementable embodiment, please refer to Figure 11 and Figure 12 , the pressing cover mechanism 3 can include a pressing block 33 and a positioning plate 332. The pressing block 33 can be configured in a long strip shape, the width of the pressing block is smaller than the distance between the two side pin boards 51 of the PCB board, and it only contacts the base body 52 of the PCB board 5 and does not contact the two side pin boards, so as to prevent affecting the batch insertion operation of the PCB board 5 and the Type-C component 4. The length of the pressing block 33 is greater than the length of the PCB board 5, that is, the distance between the positioning mechanisms 332 on both sides of the pressing block 33 is greater than the length of the PCB board 5, so that the pressing block 33 can completely fit on the PCB board, and at the same time, the positioning plate 332 can abut against both sides of the PCB board 5. The length of the positioning plate 332 protruding from the working surface of the pressing block 33 (i.e., the side facing the PCB board) is equal to the thickness of the PCB board. The positioning plate 332 can be made of a material with magnetism, and the carrier 2 can also be made of a material with magnetism, or a magnetic portion can be provided at the part in contact with the positioning plate 332, so that the carrier can just be attracted to the positioning plate 332, increasing the pressure of the pressing block 33 on the PCB and enhancing the fixing effect.

[0057] In an implementable embodiment, please refer to Figure 13 , the pressing cover mechanism 3 can include a pressing block 33 and a hinge mechanism 333. One end of the hinge mechanism 333 is fixedly connected to one end of the pressing block 33, and the other end is fixedly connected to the carrier 2, so that the end of the pressing block 33 away from the hinge can rotate around the hinge, so that the pressing block 33 approaches or moves away from the carrier 2. It can be understood that one end of the hinge can also be fixed on the boss 13 of the workbench 1.

[0058] For the above technical problems, based on the same inventive concept, please refer to Figure 1, in an implementable embodiment, a method for batch crimping of a cross-riding double-sided pin Type-C connector is further provided, including the following steps: Step 1, fixing the PCB board 5 and the Type-C component 4 at specific positions on the carrier; Step 2, fixing the carrier with the PCB board 5 and the Type-C component 4 at a predetermined position on the workbench boss; Step 3, moving the pressing cover mechanism 3 to make the pressing block 33 of the pressing cover mechanism 3 press on a specific position of the PCB board 5; Step 4, the thrust assembly 11 pushes the Type-C component 4 to insert the PCB board 5 into the Type-C component 4.

[0059] In an implementable embodiment, the Type-C component 4 is placed in the card slot 22, and the PCB board 5 is installed at a specific position on the carrier 2 through the cooperation of the second positioning hole 50 and the second positioning projection 24 on the carrier. The carrier 2 is positioned through the cooperation of the first positioning hole 23 and the first positioning projection 131 on the boss and is placed at a specific position on the boss. The push head approaches the Type-C component 4 on the carrier 2 under the action of the first slider 112, and makes the Type-C component 4 be inserted in place with the pin board 51 of the PCB board 5 under the action of the convex head 114. In this embodiment, the Type-C component is limited by the card slot 22, and the accurate placement of each workpiece is achieved by the double positioning of the carrier and the PCB board, and the carrier and the boss; through the support of the PCB board and the Type-C component, effective support is formed for each component body; with the cooperation of the pressing cover mechanism, displacement in the direction perpendicular to the PCB board is ensured not to occur; within the range of assembly error allowing the horizontal degree of the Type-C component and the PCB board to be maintained, the double-way thrust of the thrust assembly is used to successfully achieve the process of batch crimping assembly.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
