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:

[0005] A press-fitting device for a center plate and a frame of a Type-C interface includes 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 passes 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.

[0006] The first direction and the second direction are arranged at an angle. 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.

[0007] 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, when supporting before 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.

[0008] 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 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 to realize the positioning and limiting of the frame and 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.

[0009] 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.

[0010] 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 avoid contact damage to the positioning table, the frame or the central plate.

[0011] 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 assembly 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 carried out 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 fixation between the frame and the central plate, and then ensure the pressing and product quality.

[0012] 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.

[0013] 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 surface 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.

[0014] Further, rollers are respectively provided 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, the vertical drive rod is restricted to move in the vertical direction, and through the rotation of the vertical drive groove, the vertical drive rod is driven to move up and down in the vertical direction, thereby driving the preloading block to move away from or close to the positioning table in the vertical direction, and further realizing the preloading action.

[0015] 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 on the circumference 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 to 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 provided 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 move horizontally close to or away from the positioning table, and further the preloading block is driven to move horizontally close to or away from the positioning table.

[0016] According to some preferred implementation aspects of the present invention, the vertical drive groove is annularly arranged and includes a first action section and a first stationary section. When the vertical drive rod is located on the first action section, the preloading block preloads the central plate and / or the frame. When the vertical drive rod is located on the first stationary section, the horizontal height of the vertical drive rod remains unchanged. The annularly arranged vertical drive groove rotates with the rotation of the rotating wheel. When the preloading block moves horizontally, the roller at the lower part of the vertical drive 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 drive groove of the first action section decreases to press down the roller, driving the vertical drive rod, the vertical drive 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 drive groove of the first action section rises and communicates with the first stationary section, realizing the vertical upward movement of the vertical drive rod, the vertical drive block, and the preloading block away from the central plate or the frame.

[0017] According to some preferred implementation aspects of the present invention, the horizontal drive 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 drive 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 drive 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 drive rod drives the vertical drive 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 drive rod is located in 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 drive rod is located in 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.

[0018] According to some preferred implementation aspects of the present invention, the first action section of the vertical drive groove corresponds to the second stationary section of the horizontal drive groove, and the first stationary section of the vertical drive groove corresponds to the forward section and the backward section of the horizontal drive groove. The forward section and the backward section are symmetrically arranged on both sides of the second stationary section.

[0019] 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.

[0020] 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 driving the vertical driving mechanism and the horizontal driving mechanism to act simultaneously by using 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 stationary; the structure is compact and the cost is low, and no additional components are added to further increase the risk of interference.

[0021] 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.

[0022] 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. 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 central 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.

[0023] Further, the positioning table and the fixed block are both fixed on the working plate, and a guide rail is also 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 movement is realized.

[0024] 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.

[0025] 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.

[0026] 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 direction and the vertical direction.

[0027] 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 strip, and positioning holes are provided in the strip. The driving wheel has driving blocks protruding outward in the circumferential direction, and the driving blocks are inserted into the positioning holes to drive the strip to move.

[0028] Further, 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 strip to move forward.

[0029] In order to further improve the press-fitting efficiency, a strip is adopted in the present invention. A plurality of center plates are evenly spaced and arranged on each strip. 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 automatic assembly.

[0030] Further, the central plate conveying device includes a support plate and a cover plate located on the support plate. A channel for the edge of the tape to pass through is formed between the support plate and the cover plate. Meanwhile, a through hole for the clamping block in the second-direction clamping device to pass through is formed in the side of the support plate corresponding to the positioning table, so that when clamping is performed at the corresponding time, the second driving component drives the clamping block to pass through the through hole to press the frame.

[0031] According to some preferred embodiments of the present invention, a positioning pin matching with the positioning hole is provided on the positioning table, and the positioning pin is used to insert into the positioning hole to position the tape during press-fitting.

[0032] According to some preferred embodiments of the present invention, the pressing device includes a pressing block and a pressing driving component for driving the pressing block to move; the pressing driving component includes a driving plate, a vertical pressing driver for driving the driving plate to move vertically, and a horizontal pressing driver for driving the driving plate to move horizontally. The driving plate is used to connect with the pressing block. Similar to the aforementioned pre-pressing block, due to the different thicknesses of the frame and the central plate, a stepped surface similar to the first plane and the second plane is also provided on the bottom surface of the pressing block to press the frame and the central plate respectively. At the same time, avoidance holes for avoiding the second insert and the third insert are also formed in the pressing block, which will not be elaborated here.

[0033] Further, a sliding groove is formed in the driving plate, and the output shaft of the vertical pressing driver is arranged in the sliding groove, and the sliding groove is horizontally arranged.

[0034] Further, the press-fitting device includes a lifting driver. The positioning device, the first-direction clamping device and the working plate move synchronously. After the tape moves into place, the lifting driver drives the positioning device, the first-direction clamping device and the working plate to move upward to perform supporting and clamping actions on the central plate or the frame.

[0035] The present invention also provides a method for press-fitting the central plate and the frame of a Type-C interface by using the press-fitting device as described above, including the following steps:

[0036] Place the central plate and the frame on the positioning device. The positioning table supports the central plate and the frame, and the positioning member driving component drives the positioning member to penetrate through the positioning table and then position the central plate and the frame.

[0037] The first-direction clamping device acts to press the frame against the central plate in the first direction, and / or the second-direction clamping device acts to press the frame against the central plate in the second direction.

[0038] The pressing device acts to press-fit the central plate and the frame into one body.

[0039] 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.

[0040] According to some preferred embodiments 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.

[0041] 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. The assembly device includes a second moving component, which is used to drive the integrated positioning device, the first-direction clamping device, the second-direction clamping device, the pressing device, and the center plate conveying device to move together into the detection device for detection or move into the welding device for welding between the frame and the center plate.

At the same time, the frame is pressed against the center plate in the first direction and the second direction by the first-direction clamping device and the second-direction clamping device respectively, so as to fix the positions between the center plate and the frame. Finally, the center plate and the frame are press-fitted into one body by the pressing device; realizing automatic, high-precision, and high-efficiency press-fitting of the center plate and the frame.

Detailed implementation manners

[0067] To enable those skilled in the art to better understand the technical solution 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0068] Embodiment 1

[0069] Referring 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.

[0070] 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-pressing 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 against the central board 11 in the first direction, the second-direction clamping device 6 is used to press the frame 12 against 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-pressing device 4 is used to pre-press the central board 11 and / or the frame 12 before the pressing device 9 operates. The first direction and the second direction in this embodiment are arranged at an angle. 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.

[0071] In this embodiment, in order to further improve the pressing efficiency and accuracy, a form of transporting with a strip 10 is adopted. Positioning holes 101 are formed on the edge of the strip 10, and a plurality of center plates 11 are arranged at equal intervals on the strip 10. During pressing, a plurality of center plates 11 and the frame 12 are pressed 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 center plate conveying device 8 are integrated together, with a compact structure. The assembly equipment 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 center plate conveying device 8, and the product on the positioning device 3 to move together under the detection device 2 for detection or move to the welding device 1 for welding between the frame 12 and the center plate 11.

[0072] The structures of each component are introduced in detail as follows:

[0073] The positioning device 3 includes a positioning table 31, a positioning member, a positioning member driving component 33 for driving the positioning member 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 member penetrates through the positioning table 31 and is used to position the center plate 11 and the frame 12. The positioning pins 313 cooperate with the positioning holes 101 on the edge of the strip 10 and are used to insert into the positioning holes 101 during pressing to position and limit the strip 10.

[0074] 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 the horizontal height of the second plane 312. Since pressing 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 pressing, 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.

[0075] 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 extending length of the positioning member relative to the positioning table 31 and avoid interference of components. At the same time, the side of the top of the positioning member is provided with an inclined surface or an arc to facilitate passing 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.

[0076] The positioning components in this embodiment 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 passes through the positioning table 31 and is located on the outer side of the frame 12. The second insert 322 passes through the positioning table 31 and is located between the side of the center plate 11 and the inner side of the frame 12. The third insert 323 passes through the positioning table 31 and then continues to pass through the middle position of the center plate 11. That is, preferably, the first insert 321, the second insert 322, and the third insert 323 are respectively arranged to position and limit the frame 12 and the center plate 11 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. Among them, the first insert 321 and the second insert 322 are both provided in two symmetrical quantities, and the third insert 323 passes through the middle position of the center plate 11 and is provided in one quantity.

[0077] The preloading device 4 includes a preloading block 41 and a preloading drive assembly for driving the preloading block 41 to perform a preloading action. 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 the offset of the position between the frame 12 and the center plate 11, and further affect 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 fixation of the relative position between the frame 12 and the center plate 11, and further ensure the pressing and product quality.

[0078] 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.

[0079] 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.

[0080] A vertical driving groove 4211 is formed on the end face of the rotating wheel 421. The vertical driving mechanism includes a vertical driving block 422 and a vertical driving rod 423. The vertical driving block 422 is used to connect the preloading block 41. A horizontal groove 4221 is formed on the vertical driving block 422. One end of the vertical driving rod 423 is movably fitted in the horizontal groove 4221, and the other end of the vertical driving rod 423 is movably fitted in the vertical driving groove 4211. The vertical driving groove 4211 is used to drive the vertical driving rod 423 to move in the vertical direction.

[0081] Further, rollers 43 are respectively arranged at both ends of the vertical driving rod 423. The two rollers 43 are respectively received in the vertical driving groove 4211 of the rotating wheel 421 and the horizontal groove 4221 of the vertical driving block 422. The vertical driving groove 4211 is located in a vertical plane, and the horizontal groove 4221 is opened along the Y direction. The vertical driving rod 423 is restricted to move in the vertical direction. By the rotation of the vertical driving groove 4211, the vertical driving 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, realizing the preloading action.

[0082] The vertical driving groove 4211 is annularly arranged and includes a first action section 4212 and a first static section 4213. When the vertical driving rod 423 is located on the first action section 4212, the preloading block 41 preloads the center plate 11 and / or the frame 12. When the vertical driving rod 423 is located on the first static section 4213, the horizontal height of the vertical driving rod 423 remains unchanged. The annularly arranged vertical driving groove 4211 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 static section 4213, and the first static 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 decreases 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, thereby enabling the preloading block 41 to move vertically downward to contact the center plate 11 or the frame 12 to realize 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 static section 4213, realizing the vertical upward movement of the vertical driving rod 423, the vertical driving block 422 and the preloading block 41 to separate from the center plate 11 or the frame 12.

[0083] A transverse drive groove 4214 is provided in the circumferential direction of the rotating wheel 421. The transverse drive mechanism includes a mounting plate 424 and a transverse drive rod 425 located on the mounting plate 424. One end of the transverse drive rod 425 is fixed to the mounting plate 424, and the other end of the transverse drive rod 425 movably cooperates in the transverse drive groove 4214. The transverse drive groove 4214 is used to drive the transverse drive rod 425 and the mounting plate 424 to move in the horizontal direction. Preferably, an elastic reset member 44 is provided on the mounting plate 424. The elastic reset 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 provided at the lower part of the transverse drive rod 425, and the roller 43 is received in the transverse drive groove 4214. When the rotating wheel 421 rotates, through the arrangement of the transverse drive groove 4214, the roller 43 and the transverse drive rod 425, the mounting plate 424 is driven to approach or move away from the positioning table 31 horizontally, and further drives the preloading block 41 to approach or move away from the positioning table 31 horizontally. At the same time, due to the arrangement of the horizontal groove 4221 on the vertical drive block 422, although the vertical drive block 422 moves in the horizontal direction, the projection position of the vertical drive rod 423 on the horizontal plane remains unchanged.

[0084] The transverse 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 transverse drive groove 4214 is provided 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 transverse 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 transverse drive rod 425 is located in the forward section, as the rotating wheel 421 rotates, the mounting plate 424 and the preloading block 41 thereon are pushed to move in the horizontal direction towards the direction close to the positioning table 31 through the acting force between the inner wall of the forward section and the roller 43; similarly, when the roller 43 at the lower end of the transverse drive rod 425 is located in the backward section, as the rotating wheel 421 rotates, the mounting plate 424 and the preloading block 41 thereon are pushed to move in the horizontal direction away from the positioning table 31 through the acting force between the inner wall of the backward section and the roller 43.

[0085] The first action section 4212 of the vertical drive groove 4211 corresponds to the second stationary section 4216 of the horizontal 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 horizontal drive groove 4214. The forward section and the backward section are symmetrically arranged on both sides of the second stationary section 4216.

[0086] 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 horizontal drive mechanism is used to drive the preloading block 41 to approach or move away from the positioning table 31 in the horizontal direction.

[0087] When the horizontal drive mechanism drives the preloading block 41 to move horizontally, the horizontal height of the preloading block 41 remains unchanged; when the vertical drive 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 of this embodiment are indirectly fixedly connected to the vertical drive block 422 and the mounting plate 424. When the mounting plate 424 moves, the preloading block 41, the connecting plate, and the vertical drive block 422 move synchronously. In this embodiment, by opening a horizontal groove 4221 on the vertical drive block 422, the roller 43 at the top of the vertical drive rod 423 is accommodated in the horizontal groove 4221, and through the shape setting of the vertical drive groove 4211, when the rotating wheel 421 rotates and the mounting plate 424 drives the vertical drive block 422 to move back and forth, the vertical position of the vertical drive rod 423 remains stationary, thereby realizing the simultaneous driving of the vertical drive mechanism and the horizontal drive 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 are added to further increase the risk of interference.

[0088] 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 assembly for driving the first moving block 531 and the second moving block 532 to move away from each other. Both 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.

[0089] The first driving assembly includes a top block 54 and a first driver 55 for driving the movement of the top block 54. The top block 54 has a driving inclined surface 561, and the first moving block 531 and the second moving block 532 have mating inclined surfaces 562 that cooperate 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 by pushing the mating inclined surface 562 through the driving inclined surface 561, it further pushes the moving blocks towards the fixed block 51, increasing the distance between the two moving blocks, that is, the two moving blocks are opened, and the frame 12 is no longer clamped between the two moving blocks.

[0090] Furthermore, the positioning table 31 and the fixed block 51 are both fixed on the working plate 13. 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 blocks are slidably arranged on the guide rail 14. By providing the guide rail 14, the stability of the movement of multiple moving blocks is achieved.

[0091] 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 towards the frame 12 in the Y direction to press the frame 12 against the center plate 11.

[0092] The pressing device 9 includes a pressing block 91 and a pressing driving assembly for driving the movement of the pressing block 91; the pressing driving assembly includes a driving plate 92, a vertical pressing driver 93 for driving the driving plate 92 to move up and down, and a horizontal pressing driver 94 for driving the driving plate 92 to move horizontally. The driving plate 92 is used to connect with the pressing block 91. Similar to the aforementioned pre-pressing block 41, due to the different thicknesses of the frame 12 and the center plate 11, the bottom surface of the pressing block 91 also has stepped surfaces similar to the first plane 311 and the second plane 312 to press the frame 12 and the center plate 11 respectively; the pressing block 91 is also provided with avoidance holes for avoiding the second insert 322 and the third insert 323, which will not be elaborated here. At the same time, during welding, the pressing block 91 always presses the frame 12 and the center plate 11, so the position corresponding to the welding on the pressing block 91 is hollowed out to avoid affecting the welding.

[0093] Furthermore, the vertical pressing driver 93 is designed as an eccentric motor. A synchronously rotating disk is provided on the output shaft of the motor. The disk has an eccentric rod, and its axis line is located on a different straight line from the axis line of the motor output shaft. A chute 921 is opened on the driving plate 92, and the end of the eccentric rod is arranged in the chute 921, and the chute 921 is horizontally arranged. Through the operation of the motor, the eccentric rod moves in the chute 921 and drives the driving plate 92 and the pressing block 91 to move in the vertical direction to perform the pressing action.

[0094] Further, the press-fitting device includes a lifting driver 15. The positioning device 3, the first-direction clamping device 5, and the working plate 13 move synchronously. After the 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 perform a supporting and clamping action on the center plate 11 or the frame 12. While the lifting driver 15 operates, the positioning member driving assembly 33 operates to lift the height of the positioning member.

[0095] 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 at the corresponding clamping timing, the second driving assembly 62 drives the clamping block 61 to pass through the through hole to press the frame 12.

[0096] The frame conveying device 7 includes a jaw assembly 71 for gripping the frame 12 and a first moving assembly 72 for driving the jaw assembly 71 to move. The jaw assembly 71 can grip the frame 12 at the front end of the device and 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.

[0097] 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 automated assembly.

[0098] Embodiment 2

[0099] This embodiment provides a method for press-fitting the center plate 11 and the frame 12 of a Type-C interface by using the press-fitting device in Embodiment 1, including the following steps:

[0100] 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.

[0101] 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;

[0102] The pressing device 9 acts to press - fit the center plate 11 and the frame 12 into one body.

[0103] Specifically, combining the structure of the assembly device in Embodiment 1 and the steps of the above - mentioned press - fitting method, the assembly method of the center plate 11 and the frame 12 of the Type - C interface in this embodiment includes the following steps:

[0104] Step 1: Feeding the center plate 11

[0105] The tape 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 block on the circumference of the driving wheel 81 is inserted into the positioning hole 101 at the edge of the tape 10. The conveying driver 82 drives the driving wheel 81 to rotate, and conveys the tape 10 forward to the upper part of the positioning device 3.

[0106] Step 2: Positioning

[0107] When the tape 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.

[0108] While the height of the positioning table 31 is being 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 achieve the positioning and limiting of the center plate 11.

[0109] Step 3: First pre - pressing

[0110] The pre - pressing driving assembly acts. 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, then moves downward to contact the center plate 11 and presses it down to make the center plate 11 closely adhere to the first plane 311 of the positioning table 31. After the first pre - pressing is completed, the pre - pressing device 4 resets.

[0111] Step 4: Placing the frame 12

[0112] 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 a set of press-fitting center plates 11, 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 horizontally move 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.

[0113] Step 5: Second pre-pressing

[0114] The pre-pressing driving assembly acts. 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 the frame 12, and then moves downward to contact the center plate 11 and the frame 12, and presses downward to tightly press the center plate 11 against the first plane 311 of the positioning table 31 and the frame 12 against 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 realize the positioning and limiting of the frame 12 and the center plate 11. After the second pre-pressing, the pre-pressing device 4 does not reset.

[0115] Step 6: The second-direction clamping device 6 acts

[0116] The second driving assembly 62 drives the clamping block 61 to extend towards 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.

[0117] Step 7: The first-direction clamping device 5 acts

[0118] In the previous 6 steps, the first driver 55 always drives the top block 54 to move upward. Through the cooperation of the driving inclined surface 561 of the top block 54 and 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.

[0119] 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, realizing the fixation of the frame 12 in the X direction.

[0120] Step 8: The pre-pressing device 4 resets

[0121] When the first-direction clamping device 5 and the second-direction clamping device 6 act, the preloading block 41 always presses tightly against 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 the preloading device 4 resets through the cooperation of the rotating wheel 421, the vertical driving mechanism, and the horizontal driving mechanism.

[0122] Step 9, Detection

[0123] The positioning device 3 and the frame 12 and the center plate 11 thereon are moved below the detection device 2 by the second moving assembly 16 for detection to check whether the frame and the center plate are pressed and installed in place.

[0124] Step 10, Pressing and Installing

[0125] During the detection in Step 9, the pressing device 9 moves along with it. In Step 10, the second moving assembly 16 does not need to act again. The horizontal 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 to press and install the frame 12 and the center plate 11.

[0126] Step 11, The first-direction clamping device 5 and the second-direction clamping device 6 reset and then act again

[0127] The pressing device 9 in Step 10 presses the frame 12 and the center plate 11 tightly in the Z direction. On this basis, the first-direction clamping device 5 and the second-direction clamping device 6 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.

[0128] Step 12, Welding

[0129] 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 are moved into the welding device 1 by the second moving assembly 16 for welding between the frame 12 and the center plate 11. Multiple welding devices can be set to weld multiple positions simultaneously.

[0130] Since the strip 10 on the positioning table 31 has multiple center plates 11, after each group of center plates 11 and the frame 12 are welded, the second moving assembly 16 drives to move and weld the next group of center plates 11 and the frame 12.

[0131] 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.

[0132] Step 13, Reset

[0133] After all the center plates 11 and the frames 12 on the positioning table 31 are completely welded, the pressing device 9 resets, 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 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.

[0134] The pressing device 9, the first-direction clamping device 5, the second-direction clamping device 6, and the positioning device 3 are moved in the direction of the pre-pressing device 4 through the second moving assembly 16 to perform the next cycle.

[0135] The press-fitting device for the center plate 11 and the frame 12 of the Type-C interface in this embodiment uses the positioning table 31 to carry the center plate 11 and the frame 12, and drives the positioning member to penetrate the positioning table 31 through the positioning member driving assembly 33 to position the center plate 11 and the frame 12. At the same time, the first-direction clamping device 5 and the second-direction clamping device 6 press the frame 12 onto the center plate 11 in the first direction and the second direction respectively, realizing the fixation of the positions between the center plate 11 and the frame 12 of multiple products 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 through the pressing device 9, and are welded while maintaining the pressing state; realizing the automatic, highly stable, high-precision, and high-efficiency press-fitting and welding of the center plate 11 and the frame 12. 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.
