Description

Technical Field

[0001] The present invention belongs to the technical field of automated machinery, and particularly relates to a press-fitting device for a center plate and a frame of a Type-C interface, a press-fitting method based on the press-fitting device, and an assembly device for a center plate and a frame of a Type-C interface including the press-fitting device. Background Art

[0002] Existing press-fitting devices for the center plate and the frame of a Type-C interface cannot achieve automated press-fitting, with poor press-fitting accuracy and low press-fitting efficiency. Existing press-fitting devices cannot achieve clamping of the center plate or the frame in three directions of X, Y, and Z in the same device, and cannot achieve high-precision and high-efficiency press-fitting between the center plate and the frame. Summary of the Invention

[0003] In view of this, in order to overcome the defects of the prior art, the object of the present invention is to provide a press-fitting device for a center plate and a frame of a Type-C interface, which realizes automatic and high-precision press-fitting of the center plate and the frame.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A press-fitting device for a center plate and a frame of a Type-C interface, comprising a positioning device, a first-direction clamping device, a second-direction clamping device, and a pressing device. The positioning device includes a positioning table, a positioning member, and a positioning member driving assembly for driving the positioning member to move relative to the positioning table. The positioning table is used to carry the center plate and the frame. The positioning member penetrates through the positioning table and is used to position the center plate and the frame. The first-direction clamping device is used to press the frame against the center plate in the first direction. The second-direction clamping device is used to press the frame against the center plate in the second direction. The pressing device is used to press-fit the center plate and the frame into one body.

[0005] An included angle is provided between the first direction and the second direction. Preferably, the first direction is the X direction in a three-dimensional coordinate system, and the second direction is the Y direction in a three-dimensional coordinate system, that is, the first direction and the second direction are perpendicular to each other.

[0006] According to some preferred embodiments of the present invention, the positioning table has a first plane for carrying the center plate and / or a second plane for carrying the frame. The horizontal height of the first plane is higher than the horizontal height of the second plane. Since the thickness of the frame is greater than the thickness of the center plate, after press-fitting, it is necessary to make the center plate located at the center position of the thickness of the frame. Therefore, during the support before the start of press-fitting, it is necessary to make the center plate located at the center position of the thickness of the frame, that is, the height difference between the first plane and the second plane is half of the difference between the thickness of the frame and the thickness of the center plate.

[0007] According to some preferred implementation aspects of the present invention, the positioning member includes a first insert for positioning the outer side of the frame, and the first insert is located on the outer side of the frame after passing through the positioning table; and / or, a second insert for positioning the side of the central plate and the inner side of the frame, and the second insert is located between the side of the central plate and the inner side of the frame after passing through the positioning table; and / or, a third insert for positioning the central plate, and the third insert continues to pass through the middle position of the central plate after passing through the positioning table. That is, preferably, the first insert, the second insert, and the third insert are respectively arranged to position and limit the frame and the central plate on the outer side of the frame, the inner side of the frame (between the frame and the central plate), and inside the central plate. Among them, the first insert and the second insert are both provided in two symmetrical quantities, and the third insert passes through the middle position of the central plate and is provided in one quantity.

[0008] Furthermore, the top size of the positioning member is smaller than the body size of the positioning member to form a limiting step, which cooperates with the positioning table to limit the protruding length of the positioning member and avoid interference of components.

[0009] Still further, the top side of the positioning member is provided with an inclined surface or an arc to facilitate its passing through the positioning table and passing through the frame and the central plate, and to avoid contact damage to the positioning table, the frame or the central plate.

[0010] According to some preferred implementation aspects of the present invention, the pressing device includes a pre-pressing device for pre-pressing the central plate and / or the frame before the pressing device operates. The pre-pressing device includes a pre-pressing block and a pre-pressing driving component for driving the pre-pressing block to perform a pre-pressing action. Since the pressing process includes multiple action processes, such as placing the central plate, placing the frame, the first-direction clamping device operates and clamps, the second-direction clamping device operates and clamps, etc., each action is not performed simultaneously, which may cause the position offset between the frame and the central plate, and then affect the subsequent pressing and the product. Therefore, the present invention provides a pre-pressing device to pre-press the frame and / or the central plate after certain actions to ensure the relative position between the frame and the central plate is fixed, and then ensure the pressing and product quality.

[0011] According to some preferred implementation aspects of the present invention, the pre-pressing block has a third plane corresponding to the first plane and / or a fourth plane corresponding to the second plane; the first plane and the third plane cooperate to pre-press the central plate, and the second plane and the fourth plane cooperate to pre-press the frame. Since the thicknesses of the frame and the central plate are different, during pre-pressing, the central plate is accommodated between the first plane and the third plane, and the frame is accommodated between the second plane and the fourth plane. After pre-pressing, the central plate is closely attached to the first plane. The pre-pressing block is provided with avoidance holes for avoiding the second insert and the third insert.

[0012] According to some preferred implementation aspects of the present invention, the preloading drive assembly includes a rotating wheel, a preloading driver for driving the rotation of the rotating wheel, and a vertical drive mechanism for driving the preloading block to move in the vertical direction. A vertical drive groove is formed on the end face of the rotating wheel. The vertical drive mechanism includes a vertical drive block and a vertical drive rod. The vertical drive block is used to connect the preloading block. A horizontal groove is formed on the vertical drive block. One end of the vertical drive rod is movably engaged in the horizontal groove, and the other end of the vertical drive rod is movably engaged in the vertical drive groove. The vertical drive groove is used to drive the vertical drive rod to move in the vertical direction.

[0013] Further, rollers are respectively arranged at both ends of the vertical drive rod, and the two rollers are respectively received in the vertical drive groove of the rotating wheel and the horizontal groove of the vertical drive block. The vertical drive groove is located in a vertical plane, the horizontal groove is formed along the Y direction, and the vertical drive rod is restricted to move in the vertical direction. By the rotation of the vertical drive groove, the vertical drive rod is driven to move up and down in the vertical direction, and then the preloading block is driven to move away from or close to the positioning table in the vertical direction, thereby realizing the preloading action.

[0014] According to some preferred implementation aspects of the present invention, the preloading drive assembly includes a lateral drive mechanism for driving the preloading block to move in the horizontal direction. A lateral drive groove is formed in the circumferential direction of the rotating wheel. The lateral drive mechanism includes a mounting plate and a lateral drive rod located on the mounting plate. One end of the lateral drive rod is fixed on the mounting plate, and the other end of the lateral drive rod is movably engaged in the lateral drive groove. The lateral drive groove is used to drive the lateral drive rod, the mounting plate, and the vertical drive block to move in the horizontal direction. A roller is arranged at the lower part of the lateral drive rod, and the roller is received in the lateral drive groove. When the rotating wheel rotates, through the arrangement of the lateral drive groove, the roller, and the lateral drive rod, the mounting plate is driven to approach or move away from the positioning table horizontally, and then the preloading block is driven to approach or move away from the positioning table horizontally.

[0015] According to some preferred implementation aspects of the present invention, the vertical driving groove is annularly arranged and includes a first action section and a first stationary section. When the vertical driving rod is located on the first action section, the preloading block preloads the central plate and / or the frame. When the vertical driving rod is located on the first stationary section, the horizontal height of the vertical driving rod remains unchanged. The annularly arranged vertical driving groove rotates with the rotation of the rotating wheel. When the preloading block moves horizontally, the roller at the lower part of the vertical driving rod is located on the first stationary section, and the first stationary section is a section of a circular ring. When the preloading block moves vertically, the height of the top position of the inner wall of the vertical driving groove of the first action section decreases to press down the roller, driving the vertical driving rod, the vertical driving block and the preloading block to move vertically downward to contact the central plate or the frame to achieve preloading. After the preloading is completed, the height of the top position of the inner wall of the vertical driving groove of the first action section rises and communicates with the first stationary section, realizing the vertical upward movement of the vertical driving rod, the vertical driving block and the preloading block away from the central plate or the frame.

[0016] According to some preferred implementation aspects of the present invention, the horizontal driving groove includes a second action section and a second stationary section. More specifically, the second action section includes a forward section and a backward section. The forward section is used to drive the preloading block to move forward close to the positioning device, and the backward section is used to drive the preloading block to move backward away from the positioning device. The second stationary section is used to keep the projection position of the preloading block on the horizontal plane unchanged. The horizontal driving groove is opened in the circumferential direction of the rotating wheel, and the second stationary section is located in the same vertical plane. When the roller at the lower end of the horizontal driving rod is located on the second stationary section, the horizontal positions of the mounting plate and the preloading block do not move, and the vertical driving rod drives the vertical driving block to move up and down, thereby driving the preloading block to move up and down. The forward section and the backward section are inclined. When the roller at the lower end of the horizontal driving rod is located on the forward section, with the rotation of the rotating wheel, the mounting plate and the preloading block thereon are pushed to move horizontally in the direction close to the positioning table through the acting force between the inner wall of the forward section and the roller. Similarly, when the roller at the lower end of the horizontal driving rod is located on the backward section, with the rotation of the rotating wheel, the mounting plate and the preloading block thereon are pushed to move horizontally in the direction away from the positioning table through the acting force between the inner wall of the backward section and the roller.

[0017] According to some preferred implementation aspects of the present invention, the first action section of the vertical driving groove corresponds to the second stationary section of the horizontal driving groove, and the first stationary section of the vertical driving groove corresponds to the forward section and the backward section of the horizontal driving groove. The forward section and the backward section are symmetrically arranged on both sides of the second stationary section.

[0018] To avoid interference of the preloading device with other components, the preloading device approaches the positioning table and performs preloading only when preloading is required. The vertical driving mechanism is used to drive the preloading block to approach or move away from the positioning table in the vertical direction, and the horizontal driving mechanism is used to drive the preloading block to approach or move away from the positioning table in the horizontal direction.

[0019] When the horizontal driving mechanism drives the preloading block to move horizontally, the horizontal height of the preloading block remains unchanged; when the vertical driving mechanism drives the preloading block to move vertically, the projection of the preloading block on the horizontal plane remains unchanged. At the same time, the preloading block of the present invention is indirectly fixedly connected to the vertical driving block and the mounting plate. When the mounting plate moves, the preloading block and the vertical driving block move synchronously. The present invention realizes the simultaneous driving of the vertical driving mechanism and the horizontal driving mechanism by the same rotating wheel and preloading driver by providing a horizontal groove on the vertical driving block, accommodating the roller at the top of the vertical driving rod in the horizontal groove, and setting the shape of the vertical driving groove, so that when the vertical driving block moves and the rotating wheel rotates, the position of the vertical driving rod remains unchanged. The structure is compact and the cost is low, without adding additional components to further increase the risk of interference.

[0020] Further, an elastic reset member is provided on the mounting plate, and the elastic reset member is used to make the mounting plate tend to move in a direction away from the positioning table.

[0021] According to some preferred embodiments of the present invention, the first-direction clamping device includes a fixed block, a moving block, and an elastic member located between the moving block and the fixed block. The two ends of the elastic member act on the fixed block and the moving block respectively. The moving block is used to press both sides of the frame against both sides of the center plate. The moving block includes a first moving block and a second moving block respectively located on both sides of the frame. The elastic member is used to drive the first moving block and the second moving block to approach each other and clamp the frame. Each group of fixed blocks includes two fixed blocks corresponding to the first moving block and the second moving block. The fixed block is fixed, and the elastic member is used to drive the first moving block and the second moving block away from the corresponding fixed block to clamp the frame.

[0022] Further, the positioning table and the fixed block are both fixed on the working plate, and a guide rail is further provided on the working plate. The fixed block is fixed on the guide rail, and the moving block is slidably arranged on the guide rail. By providing the guide rail, the stability of the moving block during movement is realized.

[0023] According to some preferred implementation aspects of the present invention, the first-direction clamping device includes a first driving assembly for driving the first moving block and the second moving block to move away from each other. The first driving assembly includes a top block and a first driver for driving the top block to move. The top block has a driving inclined surface, and the first moving block and the second moving block have mating inclined surfaces that cooperate with the driving inclined surface. After the driving inclined surface moves upward and abuts against the mating inclined surface, it drives the first moving block and the second moving block to move away from each other. The first driver drives the top block to move upward and penetrate the working plate, and by pushing the mating inclined surface outward through the driving inclined surface, it further pushes the moving block towards the fixed block, increasing the distance between the two moving blocks, that is, the two moving blocks are opened, and the frame is no longer clamped between the two moving blocks.

[0024] According to some preferred implementation aspects of the present invention, the second-direction clamping device includes a clamping block and a second driving assembly for driving the clamping block to move in the second direction. The second driving assembly drives the clamping block to extend towards the frame in the Y direction to press the frame against the center plate.

[0025] According to some preferred implementation aspects of the present invention, the press-fitting device includes a frame conveying device for conveying the frame. The frame conveying device includes a jaw assembly for gripping the frame and a first moving assembly for driving the jaw assembly to move. The jaw assembly can grip the frame at the front end and move to above the positioning table through the first moving assembly and then descend and release the frame. That is, the first moving assembly can achieve movement in both the horizontal and vertical directions.

[0026] According to some preferred implementation aspects of the present invention, the press-fitting device includes a center plate conveying device; the center plate conveying device includes a driving wheel and a conveying driver for driving the driving wheel to rotate. A plurality of center plates are arranged on the tape, and positioning holes are provided in the tape. The driving wheel has driving blocks protruding outward on its circumference, and the driving blocks are inserted into the positioning holes to drive the tape to move.

[0027] Furthermore, the center plate conveying device includes a height driver for lifting the height of the driving wheel to lift the height of the driving wheel, insert the driving block of the driving wheel into the positioning hole, and drive the tape to move forward.

[0028] In order to further improve the press-fitting efficiency, a tape is adopted in the present invention, and a plurality of center plates are arranged at uniform intervals on each tape. Correspondingly, multiple sets of jaws, pre-pressing blocks, pressing blocks, positioning members, fixed blocks, moving blocks, clamping blocks, etc. are provided to achieve high-speed automated assembly.

[0029] Furthermore, the central plate conveying device includes a support plate and a cover plate located on the support plate, and a channel for the edge of the material strip to pass through is formed between the support plate and the cover plate. At the same time, a through hole for the clamping block in the second direction clamping device to pass through is opened on the side of the support plate corresponding to the positioning table, so that at the corresponding clamping time, the second driving component drives the clamping block to pass through the through hole to press the frame.

[0030] According to some preferred implementation aspects of the present invention, the positioning platform has a positioning pin that matches the positioning hole, and the positioning pin is used to be inserted into the positioning hole to position the material strip during press-fitting.

[0031] According to some preferred embodiments of the present invention, the clamping device includes a clamping block and a clamping drive assembly for driving the clamping block to move; the clamping drive assembly includes a drive plate, a vertical clamping drive for driving the drive plate to move vertically, and a transverse clamping drive for driving the drive plate to move horizontally, and the drive plate is used to connect with the clamping block. Similar to the aforementioned pre-compression block, due to the different thicknesses of the frame and the center plate, the bottom surface of the clamping block also has a step surface similar to the first plane and the second plane to respectively clamp the frame and the center plate. At the same time, the clamping block is also provided with an avoidance hole for avoiding the second insert and the third insert, which will not be described in detail here.

[0032] Furthermore, a slide groove is provided on the driving plate, the output shaft of the vertical clamping driver is arranged in the slide groove, and the slide groove is arranged horizontally.

[0033] Furthermore, the pressing equipment includes a lifting drive, a positioning device, a first direction clamping device and a working plate that move synchronously. After the material strip moves into place, the lifting drive drives the positioning device, the first direction clamping device and the working plate to move upward to support and clamp the center plate or the frame.

[0035] The present invention also provides an assembly device for a center plate and a frame of a Type-C interface including the above-mentioned press-fitting device.

[0036] According to some preferred implementation aspects of the present invention, the assembly device includes a detection device for detecting the center plate and the frame after being press-fitted by the press-fitting device and / or a welding device for welding the frame and the center plate.

[0037] Furthermore, the aforementioned positioning device, the first-direction clamping device, the second-direction clamping device, the pressing device, and the center plate conveying device are integrated together.

[0041] In order to enable those skilled in the art of this technology to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1

[0043] Refer to Figures 1 to 22, the assembly device for the central board 11 and the frame 12 of the Type-C interface in this embodiment includes a press-fitting device for press-fitting the central board 11 and the frame 12 into one body, a detection device 2 for detecting the pressed product, and a welding device 1 for welding between the pressed frame 12 and the central board 11. Among them, the detection device 2 includes a lighting lamp and a detection camera, and the welding device 1 can be a welding device such as a laser. The frame 12 is a U-shaped frame, and the thickness of the frame 12 is greater than the thickness of the central board 11. After the press-fitting by the press-fitting device, the central board 11 needs to be located at the central position of the thickness of the frame 12.

[0044] The press-fitting device in this embodiment includes a positioning device 3, a first-direction clamping device 5, a second-direction clamping device 6, a pre-press device 4, a pressing device 9, a frame conveying device 7, and a central board conveying device 8. Among them, the positioning device 3 is used to support and position the central board 11 and the frame 12, the first-direction clamping device 5 is used to press the frame 12 onto the central board 11 in the first direction, the second-direction clamping device 6 is used to press the frame 12 onto the central board 11 in the second direction, the pressing device 9 is used to press-fit the central board 11 and the frame 12 into one body, the frame conveying device 7 is used to convey the frame 12, the central board conveying device 8 is used to convey the central board 11, and the pre-press device 4 is used to pre-press the central board 11 and / or the frame 12 before the pressing device 9 acts. The first direction and the second direction in this embodiment are arranged at an angle. Preferably, the first direction is the X direction in the three-dimensional coordinate system, and the second direction is the Y direction in the three-dimensional coordinate system, that is, the first direction and the second direction are perpendicular to each other.

[0045] In this embodiment, in order to further improve the press-fitting efficiency and accuracy, the form of tape 10 transmission is adopted. Positioning holes 101 are opened on the edge of the tape 10, and a plurality of central boards 11 are arranged at equal intervals on the tape 10. During press-fitting, a plurality of central boards 11 and frames 12 are press-fitted synchronously. At the same time, in this embodiment, the positioning device 3, the first-direction clamping device 5, the second-direction clamping device 6, the pressing device 9, and the central board conveying device 8 are integrated together, with a compact structure. The assembly device includes a second moving component 16, which is used to drive the integrated positioning device 3, the first-direction clamping device 5, the second-direction clamping device 6, the pressing device 9, the central board conveying device 8, and the product on the positioning device 3 to move under the detection device 2 for detection or move into the welding device 1 for welding between the frame 12 and the central board 11.

[0046] The structures of each component are introduced in detail below: The positioning device 3 includes a positioning table 31, positioning members, a positioning member driving assembly 33 for driving the positioning members to move relative to the positioning table 31, and positioning pins 313 located on the positioning table 31. The positioning table 31 is used to carry the center plate 11 and the frame 12. The positioning members penetrate through the positioning table 31 and are used to position the center plate 11 and the frame 12. The positioning pins 313 are engaged with the positioning holes 101 at the edge of the strip 10 and are used to insert into the positioning holes 101 during press-fitting to position and limit the strip 10.

[0047] The positioning table 31 has a first plane 311 for carrying the center plate 11 and a second plane 312 for carrying the frame 12. The horizontal height of the first plane 311 is higher than that of the second plane 312. Since the press-fitting requires the center plate 11 to be located at the center position of the thickness of the frame 12, during the support before the start of press-fitting, it is necessary to make the center plate 11 located at the center position of the thickness of the frame 12, that is, the height difference between the first plane 311 and the second plane 312 is half of the thickness of the frame 12 minus the thickness of the center plate 11.

[0048] The top size of the positioning member is smaller than the body size of the positioning member to form a limiting step, which cooperates with the positioning table 31 to limit the protruding length of the positioning member relative to the positioning table 31 and avoid interference of components. At the same time, the top side of the positioning member is provided with an inclined surface or an arc to facilitate its penetration through the positioning table 31 and passing through the frame 12 and the center plate 11, and avoid contact damage to the positioning table 31, the frame 12 or the center plate 11.

[0049] In this embodiment, the positioning members include a first insert 321 for positioning the outer side of the frame 12, a second insert 322 for positioning the side of the center plate 11 and the inner side of the frame 12, and a third insert 323 for positioning the center plate 11. The first insert 321 is located outside the frame 12 after penetrating through the positioning table 31. The second insert 322 is located between the side of the center plate 11 and the inner side of the frame 12 after penetrating through the positioning table 31. The third insert 323 continues to penetrate through the middle position of the center plate 11 after penetrating through the positioning table 31. That is, preferably, the first insert 321, the second insert 322, and the third insert 323 are respectively arranged on the outer side of the frame 12, the inner side of the frame 12 (between the frame 12 and the center plate 11), and inside the center plate 11 to realize the positioning and limiting of the frame 12 and the center plate 11. Among them, the first insert 321 and the second insert 322 are both provided in two symmetrical quantities, and the third insert 323 penetrates through the middle position of the center plate 11 and is provided in one quantity.

[0050] The preloading device 4 includes a preloading block 41 and a preloading drive assembly for driving the preloading block 41 to perform preloading actions. Since the pressing process includes multiple action processes, such as placing the center plate 11, placing the frame 12, the first-direction clamping device 5 acting and clamping, the second-direction clamping device 6 acting and clamping, etc., each action is not carried out simultaneously, which may cause a deviation in the position between the frame 12 and the center plate 11, thereby affecting the subsequent pressing and the product. Therefore, in this embodiment, the preloading device 4 is provided to preload the frame 12 and / or the center plate 11 after certain actions to ensure the relative position between the frame 12 and the center plate 11 is fixed, thereby ensuring the pressing and product quality.

[0051] The preloading block 41 has a third plane corresponding to the first plane 311 and a fourth plane corresponding to the second plane 312; the first plane 311 and the third plane cooperate to preload the center plate 11, and the second plane 312 and the fourth plane cooperate to preload the frame 12. Since the thicknesses of the frame 12 and the center plate 11 are different, during preloading, the center plate 11 is accommodated between the first plane 311 and the third plane, and the frame 12 is accommodated between the second plane 312 and the fourth plane. After preloading, the center plate 11 is closely attached to the first plane 311. The preloading block 41 is provided with avoidance holes for avoiding the second insert 322 and the third insert 323.

[0052] The preloading drive assembly includes a rotating wheel 421, a preloading driver 426 for driving the rotating wheel 421 to rotate, a vertical drive mechanism for driving the preloading block 41 to move in the vertical direction, and a horizontal drive mechanism for driving the preloading block 41 to move in the horizontal direction.

[0053] A vertical drive groove 4211 is provided on the end face of the rotating wheel 421. The vertical drive mechanism includes a vertical drive block 422 and a vertical drive rod 423. The vertical drive block 422 is used to connect the preloading block 41. A horizontal groove 4221 is provided on the vertical drive block 422. One end of the vertical drive rod 423 moves in cooperation in the horizontal groove 4221, and the other end of the vertical drive rod 423 moves in cooperation in the vertical drive groove 4211. The vertical drive groove 4211 is used to drive the vertical drive rod 423 to move in the vertical direction.

[0054] Further, rollers 43 are respectively provided at both ends of the vertical drive rod 423. The two rollers 43 are respectively accommodated in the vertical drive groove 4211 of the rotating wheel 421 and the horizontal groove 4221 of the vertical drive block 422. The vertical drive groove 4211 is located in a vertical plane, the horizontal groove 4221 is opened along the Y direction, and the vertical drive rod 423 is restricted to move in the vertical direction. By the rotation of the vertical drive groove 4211, the vertical drive rod 423 is driven to move up and down in the vertical direction, thereby driving the preloading block 41 to move away from or close to the positioning table 31 in the vertical direction to achieve the preloading action.

[0055] The vertical driving groove 4211 is arranged in a ring shape and includes a first action section 4212 and a first stationary section 4213. When the vertical driving rod 423 is located on the first action section 4212, the preloading block 41 preloads the central plate 11 and / or the frame 12; when the vertical driving rod 423 is located on the first stationary section 4213, the horizontal height of the vertical driving rod 423 remains unchanged. The vertically driving groove 4211 arranged in a ring shape rotates with the rotation of the rotating wheel 421. When the preloading block 41 moves horizontally, the roller 43 at the lower part of the vertical driving rod 423 is located on the first stationary section 4213, and the first stationary section 4213 is a section of a circular ring; when the preloading block 41 needs to move vertically, the height of the top position of the inner wall of the vertical driving groove 4211 corresponding to the first action section 4212 drops to press down the roller 43, driving the vertical driving rod 423 to move vertically downward. The top roller 43 of the vertical driving rod 423 drags the vertical driving block 422 to move vertically downward through the inner wall of the horizontal groove 4221, so that the preloading block 41 moves vertically downward to contact the central plate 11 or the frame 12 to achieve preloading. After the preloading is completed, the height of the top position of the inner wall of the vertical driving groove 4211 of the first action section 4212 rises and communicates with the first stationary section 4213, realizing the vertical upward movement of the vertical driving rod 423, the vertical driving block 422 and the preloading block 41 to disengage from the central plate 11 or the frame 12.

[0056] A transverse driving groove 4214 is formed in the circumferential direction of the rotating wheel 421. The transverse driving mechanism includes a mounting plate 424 and a transverse driving rod 425 located on the mounting plate 424. One end of the transverse driving rod 425 is fixed to the mounting plate 424, and the other end of the transverse driving rod 425 moves in cooperation in the transverse driving groove 4214. The transverse driving groove 4214 is used to drive the transverse driving rod 425 and the mounting plate 424 to move in the horizontal direction. Preferably, an elastic resetting member 44 is arranged on the mounting plate 424, and the elastic resetting member 44 is used to make the mounting plate 424 have a tendency to move in the horizontal direction away from the positioning table 31. A roller 43 is arranged at the lower part of the transverse driving rod 425, and the roller 43 is accommodated in the transverse driving groove 4214. When the rotating wheel 421 rotates, through the arrangement of the transverse driving groove 4214, the roller 43 and the transverse driving rod 425, the mounting plate 424 is driven to move horizontally close to or away from the positioning table 31, and further drives the preloading block 41 to move horizontally close to or away from the positioning table 31. At the same time, due to the arrangement of the horizontal groove 4221 on the vertical driving block 422, although the vertical driving block 422 moves in the horizontal direction, the projection position of the vertical driving rod 423 on the horizontal plane remains stationary.

[0057] The lateral drive groove 4214 includes a second action section 4215 and a second stationary section 4216. More specifically, the second action section 4215 includes a forward section and a backward section. The forward section is used to drive the preloading block 41 to move forward and approach the positioning device 3, and the backward section is used to drive the preloading block 41 to move backward and away from the positioning device 3. The second stationary section 4216 is used to keep the projection position of the preloading block 41 on the horizontal plane unchanged. The lateral drive groove 4214 is formed in the circumferential direction of the rotating wheel 421, and the second stationary section 4216 is located in the same vertical plane. When the roller 43 at the lower end of the lateral drive rod 425 is located on the second stationary section 4216, the horizontal positions of the mounting plate 424 and the preloading block 41 remain unchanged, and the vertical drive rod 423 drives the vertical drive block 422 to move up and down, thereby driving the preloading block 41 to move up and down. The forward section and the backward section are inclined. When the roller 43 at the lower end of the lateral drive rod 425 is located on the forward section, with the rotation of the rotating wheel 421, the acting force between the inner wall of the forward section and the roller 43 pushes the mounting plate 424 and the preloading block 41 thereon to move in the horizontal direction towards the positioning table 31. Similarly, when the roller 43 at the lower end of the lateral drive rod 425 is located on the backward section, with the rotation of the rotating wheel 421, the acting force between the inner wall of the backward section and the roller 43 pushes the mounting plate 424 and the preloading block 41 thereon to move in the horizontal direction away from the positioning table 31.

[0058] The first action section 4212 of the vertical drive groove 4211 corresponds to the second stationary section 4216 of the lateral drive groove 4214, and the first stationary section 4213 of the vertical drive groove 4211 corresponds to the forward section and the backward section of the lateral drive groove 4214. The forward section and the backward section are symmetrically arranged on both sides of the second stationary section 4216.

[0059] To avoid interference of the preloading device 4 with other components, the preloading device 4 approaches the positioning table 31 and performs preloading only when preloading is required. The vertical drive mechanism is used to drive the preloading block 41 to approach or move away from the positioning table 31 in the vertical direction, and the lateral drive mechanism is used to drive the preloading block 41 to approach or move away from the positioning table 31 in the horizontal direction.

[0060] When the horizontal driving mechanism drives the preloading block 41 to move horizontally, the horizontal height of the preloading block 41 remains unchanged; when the vertical driving mechanism drives the preloading block 41 to move vertically, the projection position of the preloading block 41 on the horizontal plane remains unchanged. At the same time, multiple preloading blocks 41 in this embodiment are indirectly fixedly connected to the vertical driving block 422 and the mounting plate 424. When the mounting plate 424 moves, the preloading block 41, the connecting plate and the vertical driving block 422 move synchronously. In this embodiment, a horizontal groove 4221 is formed in the vertical driving block 422, and the roller 43 at the top of the vertical driving rod 423 is received in the horizontal groove 4221. Through the shape setting of the vertical driving groove 4211, when the rotating wheel 421 rotates and the mounting plate 424 drives the vertical driving block 422 to move back and forth, the vertical position of the vertical driving rod 423 remains stationary, thereby realizing the simultaneous driving of the vertical driving mechanism and the horizontal driving mechanism by using the same rotating wheel 421 and the preloading driver 426; the structure is compact, the cost is low, and no additional components will be added to further increase the risk of interference.

[0061] The first-direction clamping device 5 includes a fixed block 51, a moving block, an elastic member 52 located between the moving block and the fixed block 51, and a first driving component for driving the first moving block 531 and the second moving block 532 to move away from each other. The two ends of the elastic member 52 act on the fixed block 51 and the moving block respectively. The moving block is used to press the two outer sides of the frame 12 against both sides of the center plate 11. The moving block includes a first moving block 531 and a second moving block 532 respectively located on both sides of the frame 12. The elastic member 52 is used to drive the first moving block 531 and the second moving block 532 to move closer to each other and clamp the frame 12. Each set of fixed blocks 51 includes two fixed blocks 51 corresponding to the first moving block 531 and the second moving block 532. The fixed block 51 is fixed, and the elastic member 52 is used to drive the first moving block 531 and the second moving block 532 away from the corresponding fixed block 51 to clamp the frame 12.

[0062] The first driving component includes a top block 54 and a first driver 55 for driving the top block 54 to move. The top block 54 has a driving inclined surface 561, and the first moving block 531 and the second moving block 532 have a mating inclined surface 562 that cooperates with the driving inclined surface 561. After the driving inclined surface 561 moves upward and abuts against the mating inclined surface 562, it drives the first moving block 531 and the second moving block 532 to move away from each other. The first driver 55 drives the top block 54 to move upward and penetrate through the working plate 13, and pushes the mating inclined surface 562 to move outward through the driving inclined surface 561, thereby pushing the moving block closer to the fixed block 51. The distance between the two moving blocks increases, that is, the two moving blocks are opened, and the frame 12 is no longer clamped between the two moving blocks.

[0063] Furthermore, the positioning platform 31 and the fixed block 51 are both fixed on the working plate 13, and the working plate 13 is also provided with a guide rail 14, the fixed block 51 is fixed on the guide rail 14, and the moving block is slidably arranged on the guide rail 14. By providing the guide rail 14, the stability of the movement of multiple moving blocks is achieved.

[0064] The second direction clamping device 6 includes a clamping block 61 and a second driving assembly 62 for driving the clamping block 61 to move in the second direction. The second driving assembly 62 drives the clamping block 61 to extend toward the frame 12 in the Y direction to press the frame 12 against the center plate 11.

[0065] The clamping device 9 includes a clamping block 91 and a clamping drive assembly for driving the clamping block 91 to move; the clamping drive assembly includes a drive plate 92, a vertical clamping drive 93 for driving the drive plate 92 to move up and down, and a horizontal clamping drive 94 for driving the drive plate 92 to move horizontally. The drive plate 92 is used to connect with the clamping block 91. Similar to the aforementioned pre-compression block 41, due to the different thicknesses of the frame 12 and the center plate 11, the bottom surface of the clamping block 91 also has a step surface similar to the first plane 311 and the second plane 312 to respectively clamp the frame 12 and the center plate 11; the clamping block 91 is also provided with an avoidance hole for avoiding the second insert 322 and the third insert 323, which will not be repeated here. At the same time, during welding, the clamping block 91 always presses the frame 12 and the center plate 11, so the corresponding welding position on the clamping block 91 is hollowed out to avoid affecting the welding.

[0066] Furthermore, the vertical clamping driver 93 is designed as an eccentric motor, and a synchronously rotating disc is arranged on the output shaft of the motor, and an eccentric eccentric rod is arranged on the disc, and its axis line is located on a different straight line from the axis line of the motor output shaft, and a slide groove 921 is provided on the driving plate 92, and the end of the eccentric rod is arranged in the slide groove 921, and the slide groove 921 is arranged horizontally. Through the operation of the motor, the eccentric rod moves in the slide groove 921, and drives the driving plate 92 and the clamping block 91 to move in the vertical direction to perform the clamping action.

[0067] Furthermore, the press-fitting device includes a lifting driver 15, and the positioning device 3, the first direction clamping device 5 and the working plate 13 move synchronously. After the material strip 10 moves into place, the lifting driver 15 drives the positioning device 3, the first direction clamping device 5 and the working plate 13 to move upward to support and clamp the center plate 11 or the frame 12. When the lifting driver 15 is in motion, the positioning member driving assembly 33 is in motion to raise the height of the positioning member.

[0068] The center plate conveying device 8 includes a support plate 83, a cover plate 84 located on the support plate 83, a driving wheel 81, a conveying driver 82 for driving the driving wheel 81 to rotate, and a height driver 85 for lifting the height of the driving wheel 81. The driving wheel 81 has driving blocks protruding outward in the circumferential direction. The height driver 85 lifts the height of the driving wheel 81, inserts the driving blocks of the driving wheel 81 into the positioning holes 101 at the edge of the strip 10, and drives the strip 10 to move forward. A channel for the edge of the strip 10 to pass through is formed between the support plate 83 and the cover plate 84. At the same time, a through hole for the clamping block 61 in the second-direction clamping device 6 to pass through is provided on the side of the support plate 83 corresponding to the positioning table 31, so that when clamping at the corresponding time, the second driving component 62 drives the clamping block 61 to pass through the through hole to press the frame 12.

[0069] The frame conveying device 7 includes a jaw assembly 71 for clamping the frame 12 and a first moving assembly 72 for driving the jaw assembly 71 to move. The jaw assembly 71 can clamp the frame 12 at the front end of the device, move to above the positioning table 31 through the first moving assembly 72, and then descend and release the frame 12. That is, the first moving assembly 72 includes two sets of drivers to achieve movement in the horizontal and vertical directions.

[0070] In this embodiment, multiple center plates 11 are arranged on the strip 10 and are conveyed and press-fitted in the form of the strip 10. Correspondingly, multiple sets of jaws, pre-pressing blocks 41, pressing blocks 91, positioning members, fixing blocks 51, moving blocks, clamping blocks 61, etc. are provided to achieve high-speed automatic assembly.

[0071] Embodiment 2

[0072] This embodiment provides a method for press-fitting the center plate 11 of a Type-C interface and the frame 12 using the press-fitting device in Embodiment 1, including the following steps: Place the center plate and the frame 12 on the positioning device 3. The positioning table 31 supports the center plate and the frame 12. The positioning member driving assembly 33 drives the positioning member to penetrate the positioning table 31 and then positions the center plate and the frame 12. The first-direction clamping device 5 acts to press the frame 12 against the center plate 11 in the first direction, and the second-direction clamping device 6 acts to press the frame 12 against the center plate 11 in the second direction. The pressing device 9 acts to press-fit the center plate 11 and the frame 12 into one body.

[0073] Specifically, combining the structure of the assembly device in Embodiment 1 and the steps of the above press-fitting method, the assembly method of the center plate 11 of the Type-C interface and the frame 12 in this embodiment includes the following steps: Step 1. Feeding of the center plate 11 The strip 10 enters between the support plate 83 and the cover plate 84. The height driver 85 raises the horizontal height of the conveying driver 82 and the driving wheel 81, so that the driving blocks on the circumference of the driving wheel 81 are inserted into the positioning holes 101 at the edge of the strip 10. The conveying driver 82 drives the driving wheel 81 to rotate, and conveys the strip 10 forward to the upper part of the positioning device 3.

[0074] Step 2: Positioning When the strip 10 is conveyed to the upper part of the positioning device 3, the lifting driver 15 drives the positioning device 3, the first-direction clamping device 5 and the working plate 13 to move upward. The positioning table 31 in the positioning device 3 contacts the center plate 11 to support the center plate 11.

[0075] While the height of the positioning table 31 is raised, the positioning member driving assembly 33 drives the positioning members (the first insert 321, the second insert 322, the third insert 323) to move upward through the positioning table 31 and continue to rise above the center plate 11. The second insert 322 and the third insert 323 realize the positioning and limiting of the center plate 11.

[0076] Step 3: First pre-pressing The pre-pressing driving assembly operates. Through the cooperation of the rotating wheel 421, the vertical driving mechanism and the horizontal driving mechanism, the pre-pressing block 41 extends forward and moves above the center plate 11, and then moves downward to contact the center plate 11 and presses down to press the center plate 11 tightly against the first plane 311 of the positioning table 31. After the first pre-pressing is completed, the pre-pressing device 4 resets.

[0077] Step 4: Place the frame 12 The jaw assembly 71 grabs the frame 12. The number of jaws and the number of frames 12 grabbed are the same as the number of center plates 11 in a set of press-fittings, corresponding to the number of the first planes 311 on the positioning table 31. After the first moving assembly 72 drives the jaw assembly 71 to move horizontally above the positioning table 31, the jaw assembly 71 moves downward to the positioning table 31 and releases the jaws, placing the frame 12 on the second plane 312 of the positioning table 31. Then the jaw assembly 71 resets and waits for the next grab.

[0078] Step 5: Second pre-pressing The preloading drive assembly operates. Through the cooperation of the rotating wheel 421, the vertical drive mechanism, and the horizontal drive mechanism, the preloading block 41 extends forward and moves above the center plate 11 and the frame 12, and then moves downward to contact the center plate 11 and the frame 12, and presses downward to closely attach the center plate 11 to the first plane 311 of the positioning table 31 and the frame 12 to the second plane 312 of the positioning table 31, so that the first insert 321 is located outside the frame 12, the second insert 322 is located between the side of the center plate 11 and the inside of the frame 12, and the first insert 321, the second insert 322, and the third insert 323 achieve the positioning and limiting of the frame 12 and the center plate 11. After the second preloading, the preloading device 4 does not reset.

[0079] Step 6: The second-direction clamping device 6 operates. The second drive assembly 62 drives the clamping block 61 to extend toward the frame 12 in the Y direction through the through hole between the support plate 83 and the cover plate 84 to press the frame 12 against the center plate 11.

[0080] Step 7: The first-direction clamping device 5 operates. In the previous 6 steps, the first driver 55 always drives the top block 54 to move upward. Through the driving inclined surface 561 of the top block 54 to push the mating inclined surface 562 of the moving block, the distance between the two moving blocks is greater than the width of the frame 12, so that the frame 12 can be placed on the positioning table 31.

[0081] After waiting for step 6 to end, the first driver 55 drives the top block 54 to move downward. Through the reset action of the elastic member 52 between the fixed and moving blocks, the distance between the two moving blocks decreases, and finally the frame 12 is clamped on the center plate 11 to achieve the fixation of the frame 12 in the X direction.

[0082] Step 8: The preloading device 4 resets. When the first-direction clamping device 5 and the second-direction clamping device 6 operate, the preloading block 41 always presses the frame 12 and the center plate 11. After the moving block clamps the frame 12, the preloading block 41 disengages from the center plate 11, and through the cooperation of the rotating wheel 421, the vertical drive mechanism, and the horizontal drive mechanism, the preloading device 4 resets.

[0083] Step 9: Detection The second moving component 16 moves the positioning device 3 and the frame 12 and the center plate 11 thereon to the lower part of the detection device 2 for detection to check whether the frame and the center plate are press-fitted in place.

[0084] Step 10: Press-fitting During the detection in Step 9, the pressing device 9 moves along with it. In Step 10, the second moving component 16 does not need to act again. The lateral pressing driver 94 pushes the pressing block 91 forward, and the vertical pressing driver 93 drives the driving plate 92 and the pressing block 91 to move downward through the driving plate 92 and the sliding groove 921 thereon, so as to press-fit the frame 12 and the center plate 11.

[0085] Step 11: After the first-direction clamping device 5 and the second-direction clamping device 6 are reset, they act again. The pressing device 9 in Step 10 presses the frame 12 and the center plate 11 in the Z direction. On this basis, the first-direction clamping device 5 and the second-direction clamping device 6 are first reset and then act again to clamp the frame 12 and the center plate 11 from the X direction and the Y direction, thereby realizing the clamping and fixing of the frame 12 and the center plate 11 in the three directions of X, Y, and Z.

[0086] Step 12: Welding The second moving component 16 moves the pressing device 9, the first-direction clamping device 5, the second-direction clamping device 6, the positioning device 3 and the frame 12 and the center plate 11 thereon to the welding device 1 for welding between the frame 12 and the center plate 11. Multiple welding devices can be set to weld multiple positions simultaneously.

[0087] Since there are multiple center plates 11 on the strip 10 on the positioning table 31, after each group of center plates 11 and frames 12 are welded, the second moving component 16 drives to move and weld the next group of center plates 11 and frames 12.

[0088] During welding, the frame 12 and the center plate 11 are clamped and fixed in the three directions of X, Y, and Z, with higher precision. The position corresponding to the welding on the pressing block 91 is hollowed out to avoid affecting welding.

[0089] Step 13: Reset After all the center plates 11 and frames 12 on the positioning table 31 are welded, the pressing device 9 is reset, and the pressing block 91 disengages from the frame 12 and the center plate 11; the first-direction clamping device 5 and the second-direction clamping device 6 are reset, and the clamping block 61 and the moving block disengage from the frame 12 and the center plate 11; the positioning member in the positioning device 3 moves downward and disengages from the frame 12 and the center plate 11. The strip 10 is transmitted backward through the driving wheel 81 and the conveying driver 82.

[0090] The second moving component 16 moves the pressing device 9, the first-direction clamping device 5, the second-direction clamping device 6, and the positioning device 3 in the direction of the pre-pressing device 4 for the next cycle.

[0091] The press-fitting device for the center plate 11 and the frame 12 of the Type-C interface in this embodiment uses a positioning table 31 to carry the center plate 11 and the frame 12, and drives a positioning member through the positioning table 31 by a positioning member driving assembly 33 to position the center plate 11 and the frame 12. At the same time, the frame 12 is pressed against the center plate 11 in the first direction and the second direction by a first-direction clamping device 5 and a second-direction clamping device 6 respectively, so as to fix the positions between the center plate 11 and the frame 12 in multiple products and in multiple directions, ensuring the assembly accuracy of the center plate 11 and the U-shaped frame. Finally, the center plate 11 and the frame 12 are press-fitted into one body by a pressing device 9 and welded while maintaining the pressed state; the automatic, highly stable, high-precision, and high-efficiency press-fitting and welding of the center plate 11 and the frame 12 are realized. It solves the problems of unstable assembly and welding dimensional accuracy, low yield rate, and slow welding speed of the center plate 11 and the frame 12 of the Type-C interface.
