Description

[0001] This application is a divisional application of the invention patent application with the application date of April 29, 2025, application number 2025105511548, and invention name “Pressing equipment, pressing method and assembly equipment for the center board and frame of the Type-C interface”. Technical Field

[0002] The present invention belongs to the field of automated machinery technology, and in particular relates to an assembly device for a center plate and a frame of a Type-C interface. Background Art

[0003] Existing press-fitting equipment for Type-C connectors, such as the center plate and frame, cannot achieve automated press-fitting, resulting in poor precision and low efficiency. Existing press-fitting equipment cannot clamp the center plate or frame in three directions (X, Y, and Z) within the same device, making it impossible to achieve high-precision and efficient press-fitting between the center plate and frame. Summary of the Invention

[0004] In view of this, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a press-fitting device for the center plate and the frame of the Type-C interface, so as to realize automatic and high-precision press-fitting of the center plate and the frame.

[0005] In order 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 includes a positioning device, a first-direction clamping device, a second-direction clamping device, and a pressing device. The positioning device includes a positioning platform, a positioning member, and a positioning member driving assembly for driving the positioning member to move relative to the positioning platform. The positioning platform is used to support the center plate and the frame. The positioning member passes through the positioning platform and is used to position the center plate and the frame. The first-direction clamping device is used to press the frame onto the center plate in a first direction. The second-direction clamping device is used to press the frame onto the center plate in a second direction. The pressing device is used to press the center plate and the frame into one.

[0006] The first direction and the second direction 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.

[0007] According to some preferred embodiments of the present invention, the positioning platform has a first plane for supporting the center plate and / or a second plane for supporting the frame, and the first plane is higher than the second plane. Since the frame is thicker than the center plate, the center plate needs to be positioned at the center of the frame thickness after press-fitting. Therefore, during support before press-fitting, the center plate needs to be positioned at the center of the frame thickness, i.e., the height difference between the first plane and the second plane is one-half the thickness of the frame minus the thickness of the center plate.

[0008] According to some preferred embodiments of the present invention, the positioning member includes a first insert for positioning the outside of the frame, the first insert being located on the outside of the frame after passing through the positioning platform; and / or a second insert for positioning the side of the center plate and the inside of the frame, the second insert being located between the side of the center plate and the inside of the frame after passing through the positioning platform; and / or a third insert for positioning the center plate, the third insert passing through the positioning platform and continuing to pass through the middle of the center plate. That is, the first insert, the second insert, and the third insert are preferably arranged on the outside of the frame, the inside of the frame (between the frame and the center plate), and the inside of the center plate, respectively, to realize the positioning and limiting of the frame and the center plate. The first insert and the second insert are both symmetrically arranged in two numbers, and the third insert passes through the middle of the center plate and is arranged in one number.

[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 platform to limit the protruding length of the positioning member to avoid interference with components.

[0010] Furthermore, the top side of the positioning member is inclined or arc-shaped to facilitate its penetration through the positioning platform and through the frame and center plate, thereby avoiding contact damage to the positioning platform, frame or center plate.

[0011] According to some preferred embodiments of the present invention, the pressing device includes a pre-pressing device for pre-pressing the center plate and / or the frame before the pressing device is actuated, and the pre-pressing device includes a pre-pressing block and a pre-pressing drive 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 center plate, placing the frame, actuating and clamping the clamping device in the first direction, actuating and clamping the clamping device in the second direction, etc., each action is not performed simultaneously, which may cause a positional offset between the frame and the center plate, thereby affecting subsequent pressing and product. Therefore, the present invention is provided with a pre-pressing device to pre-press the frame and / or the center plate after certain actions to ensure that the relative position between the frame and the center plate is fixed, thereby ensuring the pressing and product quality.

[0012] According to some preferred embodiments 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 and third planes cooperate to pre-press the center plate, and the second and fourth planes cooperate to pre-press the frame. Due to the different thicknesses of the frame and the center plate, during pre-pressing, the center plate is accommodated between the first and third planes, and the frame is accommodated between the second and fourth planes. After pre-pressing, the center plate is tightly attached to the first plane. The pre-pressing block is provided with an escape hole for evading the second and third inserts.

[0013] According to some preferred embodiments of the present invention, the prestressing drive assembly includes a rotating wheel, a prestressing driver for driving the rotating wheel to rotate, and a vertical driving mechanism for driving the prestressing block to move in a vertical direction. A vertical driving groove is provided on the end surface of the rotating wheel. The vertical driving mechanism includes a vertical driving block and a vertical driving rod. The vertical driving block is used to connect the prestressing block. A horizontal groove is provided on the vertical driving block. One end of the vertical driving rod moves in cooperation in the horizontal groove, and the other end of the vertical driving rod moves in cooperation in the vertical driving groove. The vertical driving groove is used to drive the vertical driving rod to move in the vertical direction.

[0014] Furthermore, rollers are provided at each end of the vertical drive rod, housed in the vertical drive slot of the rotating wheel and the horizontal slot of the vertical drive block, respectively. The vertical drive slot is located on a vertical plane, and the horizontal slot extends along the Y direction. The vertical drive rod is constrained to move vertically. Rotation of the vertical drive slot drives the vertical drive rod up and down, thereby driving the preload block vertically away from or closer to the positioning platform, thereby achieving preloading.

[0015] According to some preferred embodiments of the present invention, the pre-stressing drive assembly includes a transverse drive mechanism for driving the pre-stressing block to move in the horizontal direction, a transverse drive groove is provided on the circumference of the rotating wheel, and the transverse drive mechanism includes a mounting plate and a transverse drive rod located on the mounting plate, one end of the transverse drive rod is fixed to the mounting plate, and the other end of the transverse drive rod moves in cooperation in the transverse drive groove, and the transverse drive groove is used to drive the transverse 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 transverse drive rod, and the roller is accommodated in the transverse drive groove. The rotating wheel rotates, and through the arrangement of the transverse drive groove, the roller and the transverse drive rod, the mounting plate is driven horizontally toward or away from the positioning platform, thereby driving the pre-stressing block horizontally toward or away from the positioning platform.

[0016] According to some preferred embodiments of the present invention, the vertical drive groove is annular and includes a first action section and a first static section. When the vertical drive rod is located in the first action section, the pre-load block pre-loads the center plate and / or the frame. When the vertical drive rod is located in the first static section, the horizontal height of the vertical drive rod remains unchanged. The annular vertical drive groove rotates with the rotation of the rotating wheel. When the pre-load block moves horizontally, the roller at the bottom of the vertical drive rod is located in the first static section, which is a section of a circular ring. When the pre-load block moves vertically, the top of the inner wall of the vertical drive groove in the first action section descends, pressing the roller downward, driving the vertical drive rod, the vertical drive block, and the pre-load block to move vertically downward to contact the center plate or frame to achieve pre-load. After pre-load is completed, the top of the inner wall of the vertical drive groove in the first action section rises and connects with the first static section, allowing the vertical drive rod, the vertical drive block, and the pre-load block to move vertically upward and away from the center plate or frame.

[0017] According to some preferred embodiments of the present invention, the transverse drive groove includes a second action section and a second static section. More specifically, the second action section includes a forward section and a backward section. The forward section is used to drive the preload block forward toward the positioning device, the backward section is used to drive the preload block backward away from the positioning device, and the second static section is used to maintain the projected position of the preload block on the horizontal plane unchanged. The transverse drive groove is opened on the circumference of the rotating wheel, wherein the second static section is located on the same vertical plane. When the roller at the lower end of the transverse drive rod is located on the second static section, the horizontal position of the mounting plate and the preload block remains stationary, and the vertical drive rod drives the vertical drive block to move up and down, thereby driving the preload block to move up and down. The forward section and the backward section are inclined. When the roller at the lower end of the transverse driving rod is located in the forward section, as the rotating wheel rotates, the force between the groove wall in the forward section and the roller pushes the mounting plate and the pre-loaded block thereon to move in the horizontal direction toward the positioning platform; similarly, when the roller at the lower end of the transverse driving rod is located in the backward section, as the rotating wheel rotates, the force between the groove wall in the backward section and the roller pushes the mounting plate and the pre-loaded block thereon to move in the horizontal direction away from the positioning platform.

[0018] According to some preferred embodiments of the present invention, the first action section of the vertical drive trough corresponds to the second static section of the transverse drive trough, and the first static section of the vertical drive trough corresponds to the forward section and the backward section of the transverse drive trough. The forward section and the backward section are symmetrically arranged on either side of the second static section.

[0019] In order to avoid interference of the pre-stressing device with other components, the pre-stressing device approaches the positioning table and performs pre-stressing only when pre-stressing is required. The vertical drive mechanism is used to drive the pre-stressing block towards or away from the positioning table in the vertical direction, and the horizontal drive mechanism is used to drive the pre-stressing block towards or away from the positioning table in the horizontal direction.

[0020] When the transverse drive mechanism drives the pre-load block to move horizontally, the horizontal height of the pre-load block remains unchanged; when the vertical drive mechanism drives the pre-load block to move vertically, the projection of the pre-load block on the horizontal plane remains unchanged. At the same time, the pre-load block of the present invention is indirectly fixedly connected to the vertical drive block and the mounting plate. When the mounting plate moves, the pre-load block and the vertical drive block move synchronously. The present invention provides a horizontal groove on the vertical drive block, and the roller at the top of the vertical drive rod is accommodated in the horizontal groove. The shape of the vertical drive groove is set so that when the vertical drive block moves and the rotating wheel rotates, the position of the vertical drive rod remains unchanged, thereby realizing the use of the same rotating wheel and pre-load driver to simultaneously drive the vertical drive mechanism and the transverse drive mechanism. The structure is compact and the cost is low, and no additional components are added to further increase the risk of interference.

[0021] Furthermore, an elastic reset member is provided on the mounting plate, and the elastic reset member is used to make the mounting plate have a tendency to move in a direction away from the positioning platform.

[0022] According to some preferred embodiments of the present invention, the first-direction clamping device includes a fixed block, a movable block, and an elastic member located between the movable block and the fixed block, the two ends of the elastic member acting on the fixed block and the movable block respectively, the movable block is used to press the two sides of the frame onto the two sides of the center plate, the movable block includes a first movable block and a second movable block respectively located on both sides of the frame, and the elastic member is used to drive the first movable block and the second movable block to approach each other and clamp the frame. Each group of fixed blocks includes two fixed blocks corresponding to the first movable block and the second movable block. The fixed blocks are fixed and stationary, and the elastic member is used to drive the first movable block and the second movable block away from the corresponding fixed blocks to clamp the frame.

[0023] Furthermore, the positioning platform and the fixed block are both fixed on a working plate, the working plate is further provided with a guide rail, the fixed block is fixed on the guide rail, and the moving block is slidably provided on the guide rail. By providing the guide rail, the stability of the moving block is achieved.

[0024] According to some preferred embodiments of the present invention, the first-direction clamping device includes a first driving assembly for driving the first movable block and the second movable 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 bevel, the first movable block and the second movable block have a matching bevel that matches the driving bevel, and after the driving bevel moves upward and contacts the matching bevel, the first movable block and the second movable block are driven to move away from each other. The first driver drives the top block to move upward and pass through the working plate, and pushes the matching bevel outward through the driving bevel, thereby pushing the movable block closer to the fixed block, and the spacing between the two movable blocks increases, that is, the two movable blocks are opened, and the frame is no longer clamped between the two movable blocks.

[0025] According to some preferred embodiments 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 toward the frame in the Y direction to press the frame against the center plate.

[0026] According to some preferred embodiments of the present invention, the press-fitting device includes a frame conveying device for conveying the frame, the frame conveying device including a clamping jaw assembly for clamping the frame and a first movable assembly for driving the clamping jaw assembly to move. The clamping jaw assembly is capable of clamping the frame at its front end and moving it above the positioning platform via the first movable assembly, after which it descends and releases the frame. In other words, the first movable assembly is capable of simultaneous horizontal and vertical movement.

[0030] Furthermore, the central plate conveyor device includes a support plate and a cover plate positioned above the support plate, with a passage formed between the support plate and the cover plate for the edge of the material strip to pass through. Simultaneously, a through-hole for a clamping block in the second-direction clamping device to pass through is provided on the side of the support plate corresponding to the positioning platform. At the appropriate clamping opportunity, the second drive assembly drives the clamping block through the through-hole to compress the frame.

[0031] According to some preferred embodiments 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.

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention. Example 1

[0043] Reference Figures 1 to 22 The assembly equipment for the center plate 11 and the frame 12 of the Type-C interface of this embodiment includes a press-fitting device for press-fitting the center plate 11 and the frame 12 into one piece, a detection device 2 for detecting the pressed product, and a welding device 1 for welding the pressed frame 12 and the center plate 11. 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 that of the center plate 11. After the press-fitting device is pressed, the center plate 11 needs to be located at the center of the thickness of the frame 12.

[0044] The pressing 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 center plate conveying device 8. Among them, the positioning device 3 is used to support and position the center plate 11 and the frame 12, the first-direction clamping device 5 is used to press the frame 12 onto the center plate 11 in the first direction, the second-direction clamping device 6 is used to press the frame 12 onto the center plate 11 in the second direction, the pressing device 9 is used to press the center plate 11 and the frame 12 into one, the frame conveying device 7 is used to convey the frame 12, the center plate conveying device 8 is used to convey the center plate 11, and the pre-pressing device 4 is used to pre-press the center plate 11 and / or the frame 12 before the pressing device 9 is actuated. In this embodiment, the first direction and the second direction are set 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 order to further improve the efficiency and accuracy of press-fitting in this embodiment, a material strip 10 is used for transmission. Positioning holes 101 are provided on the edge of the material strip 10. A plurality of center plates 11 are evenly spaced and arranged on the material strip 10. During press-fitting, the plurality of center plates 11 and the frame 12 are press-fitted simultaneously. 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, resulting in 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 and the center plate conveying device 8 and the product on the positioning device 3 to move together to the detection device 2 for detection or to move to the welding device 1 for welding between the frame 12 and the center plate 11.

[0046] The following is a detailed introduction to the structure of each component: The positioning device 3 includes a positioning platform 31, a positioning member, a positioning member driving assembly 33 for driving the positioning member to move relative to the positioning platform 31, and a positioning pin 313 located on the positioning platform 31. The positioning platform 31 is used to support the center plate 11 and the frame 12. The positioning member passes through the positioning platform 31 and is used to position the center plate 11 and the frame 12. The positioning pin 313 cooperates with the positioning hole 101 on the edge of the material strip 10 and is used to insert into the positioning hole 101 to position and limit the material strip 10 during press-fitting.

[0047] The positioning platform 31 has a first flat surface 311 for supporting the center panel 11 and a second flat surface 312 for supporting the frame 12. The first flat surface 311 is higher than the second flat surface 312. Because press-fitting requires the center panel 11 to be centered within the thickness of the frame 12, the support prior to press-fitting ensures that the center panel 11 is centered within the thickness of the frame 12. Specifically, the height difference between the first flat surface 311 and the second flat surface 312 is one-half the thickness of the frame 12 minus the thickness of the center panel 11.

[0048] The top of the positioning member is smaller than the main body of the positioning member, forming a limiting step. This step, in conjunction with the positioning platform 31, limits the positioning member's extension relative to the positioning platform 31, preventing interference with other components. Furthermore, the top side of the positioning member is beveled or curved to facilitate its passage through the positioning platform 31, the frame 12, or the center panel 11, avoiding contact damage to the positioning platform 31, the frame 12, or the center panel 11.

[0049] The positioning members 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 platform 31 and is located on the outer side of the frame 12. The second insert 322 passes through the positioning platform 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 platform 31 and continues through the middle of the center plate 11. Specifically, the first insert 321, the second insert 322, and the third insert 323 are preferably positioned 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 the interior of the center plate 11, respectively, to position and limit the frame 12 and the center plate 11. The first insert 321 and the second insert 322 are both symmetrically arranged in pairs, while the third insert 323 passes through the middle of the center plate 11 and is arranged in pairs.

[0050] The pre-pressing device 4 includes a pre-pressing block 41 and a pre-pressing drive assembly for driving the pre-pressing block 41 to perform a pre-pressing action. Since the press-fitting process includes multiple action processes, such as placing the center plate 11, placing the frame 12, actuating and clamping the first-direction clamping device 5, actuating and clamping the second-direction clamping device 6, etc., each action is not performed simultaneously, which may cause the position of the frame 12 and the center plate 11 to shift, thereby affecting the subsequent press-fitting and product. Therefore, the present embodiment is provided with a pre-pressing device 4 to pre-press the frame 12 and / or the center plate 11 after certain actions to ensure that the relative position between the frame 12 and the center plate 11 is fixed, thereby ensuring press-fitting and product quality.

[0051] The pre-pressing 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 pre-press the center plate 11, and the second plane 312 and the fourth plane cooperate to pre-press the frame 12. Due to the different thicknesses of the frame 12 and the center plate 11, during pre-pressing, 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 pre-pressing, the center plate 11 is tightly attached to the first plane 311. The pre-pressing block 41 is provided with a clearance hole for accommodating 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 driving mechanism for driving the preloading block 41 to move in the vertical direction, and a transverse driving mechanism for driving the preloading block 41 to move in the horizontal direction.

[0053] A vertical driving groove 4211 is provided on the end face of the rotating wheel 421, and 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 pre-load block 41. A horizontal groove 4221 is provided on the vertical driving block 422. One end of the vertical driving rod 423 moves in the horizontal groove 4221, and the other end of the vertical driving rod 423 moves 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.

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

[0055] The vertical drive groove 4211 is arranged in an annular shape, including a first action section 4212 and a first stationary section 4213. When the vertical drive rod 423 is located on the first action section 4212, the pre-compression block 41 pre-compresses the center plate 11 and / or the frame 12; when the vertical drive rod 423 is located on the first stationary section 4213, the horizontal height of the vertical drive rod 423 remains unchanged. The annular vertical driving groove 4211 rotates with the rotation of the rotating wheel 421. When the pre-compression 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 pre-compression block 41 needs to move vertically, the top position height of the inner wall of the vertical driving groove 4211 corresponding to the first action section 4212 is lowered to press down the roller 43, thereby 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 causing the pre-compression block 41 to move vertically downward to contact the center plate 11 or the frame 12 to achieve pre-compression. After the pre-compression is completed, the top position of the inner wall of the vertical driving groove 4211 of the first action section 4212 rises and connects with the first static section 4213, so that the vertical driving rod 423 and the vertical driving block 422 and the pre-compression block 41 move vertically upward and separate from the center plate 11 or the frame 12.

[0056] A transverse drive slot 4214 is defined around the circumference 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 moves in conjunction with the transverse drive slot 4214. The transverse drive slot 4214 is used to drive the transverse drive rod 425 and the mounting plate 424 to move horizontally. Preferably, an elastic reset member 44 is provided on the mounting plate 424 to cause the mounting plate 424 to move horizontally away from the positioning platform 31. A roller 43 is provided at the bottom of the transverse drive rod 425 and is accommodated in the transverse drive slot 4214. As the rotating wheel 421 rotates, the transverse drive slot 4214, roller 43, and transverse drive rod 425 drive the mounting plate 424 to move horizontally toward or away from the positioning platform 31, thereby driving the preload block 41 to move horizontally toward or away from the positioning platform 31. At the same time, due to the arrangement of the horizontal slot 4221 on the vertical driving block 422 , although the vertical driving block 422 moves in the horizontal direction, the projected position of the vertical driving rod 423 on the horizontal plane remains stationary.

[0057] 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 preload block 41 forward toward the positioning device 3, the backward section is used to drive the preload block 41 backward away from the positioning device 3, and the second stationary section 4216 is used to maintain the projected position of the preload block 41 on the horizontal plane. The transverse drive groove 4214 is provided on the circumference of the rotating wheel 421, wherein the second stationary section 4216 is located on 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 position of the mounting plate 424 and the preload block 41 remains stationary, and the vertical drive rod 423 drives the vertical drive block 422 to move up and down, thereby driving the preload 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 driving rod 425 is located in the forward section, as the rotating wheel 421 rotates, the force between the groove wall in the forward section and the roller 43 pushes the mounting plate 424 and the pre-loaded block 41 thereon to move in the horizontal direction toward the positioning platform 31; similarly, when the roller 43 at the lower end of the transverse driving rod 425 is located in the backward section, as the rotating wheel 421 rotates, the force between the groove wall in the backward section and the roller 43 pushes the mounting plate 424 and the pre-loaded block 41 thereon to move in the horizontal direction away from the positioning platform 31.

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

[0059] In order to avoid interference of the pre-stressing device 4 with other components, the pre-stressing device 4 approaches the positioning platform 31 and performs pre-stressing only when pre-stressing is required. The vertical drive mechanism is used to drive the pre-stressing block 41 towards or away from the positioning platform 31 in the vertical direction, and the horizontal drive mechanism is used to drive the pre-stressing block 41 towards or away from the positioning platform 31 in the horizontal direction.

[0060] When the transverse drive mechanism drives the pre-load block 41 to move horizontally, the horizontal height of the pre-load block 41 remains unchanged; when the vertical drive mechanism drives the pre-load block 41 to move vertically, the projected position of the pre-load block 41 on the horizontal plane remains unchanged. Furthermore, in this embodiment, the multiple pre-load blocks 41 are indirectly fixedly connected to the vertical drive block 422 and the mounting plate 424. When the mounting plate 424 moves, the pre-load blocks 41, the connecting plate, and the vertical drive block 422 move synchronously. In this embodiment, a horizontal groove 4221 is provided on the vertical drive block 422, and the roller 43 at the top of the vertical drive rod 423 is accommodated in the horizontal groove 4221. Furthermore, the shape of the vertical drive groove 4211 is configured so that when the rotating wheel 421 rotates and the mounting plate 424 drives the vertical drive block 422 to move forward and backward, the vertical drive rod 423 remains in its vertical position. This allows the use of the same rotating wheel 421 and pre-load driver 426 to simultaneously drive the vertical drive mechanism and the transverse drive mechanism. This structure is compact and low-cost, and does not add additional components that increase the risk of interference.

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

[0062] The first drive assembly includes a top block 54 and a first driver 55 for driving the top block 54. The top block 54 has a driving bevel 561. The first and second movable blocks 531 and 532 have mating bevels 562 that mate with the driving bevel 561. After the driving bevel 561 moves upward and abuts against the mating bevel 562, the first and second movable blocks 531 and 532 are driven away from each other. The first driver 55 drives the top block 54 upward and through the working plate 13. The driving bevel 561 pushes the mating bevel 562 outward, thereby pushing the movable blocks toward the fixed block 51. The spacing between the two movable blocks increases, i.e., the space between the two movable blocks opens, and the frame 12 is no longer clamped between the two movable blocks.

[0063] Furthermore, the positioning platform 31 and the fixed block 51 are fixed on the working plate 13, and the working plate 13 is further provided with a guide rail 14. The fixed block 51 is fixed on the guide rail 14, and the moving block is slidably provided 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 described in detail 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. A synchronously rotating disc is mounted on the motor's output shaft. The disc has an eccentric rod, whose axis is aligned with that of the motor's output shaft. A horizontally disposed slot 921 is provided on the drive plate 92, into which the end of the eccentric rod is positioned. The motor's operation causes the eccentric rod to move within the slot 921, driving the drive plate 92 and the clamping block 91 to move vertically, thereby performing the clamping operation.

[0067] Furthermore, the press-fitting apparatus includes a lifting drive 15, which synchronizes the movement of the positioning device 3, the first-direction clamping device 5, and the working plate 13. After the strip 10 is moved into position, the lifting drive 15 drives the positioning device 3, the first-direction clamping device 5, and the working plate 13 upward to support and clamp the center panel 11 or the frame 12. Simultaneously with the movement of the lifting drive 15, the positioning member drive assembly 33 operates 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 raising the height of the driving wheel 81. The driving wheel 81 has a driving block protruding outward on its circumference. The height driver 85 raises the height of the driving wheel 81 and inserts the driving block of the driving wheel 81 into the positioning hole 101 at the edge of the material belt 10 to drive the material belt 10 forward. A channel for the edge of the material belt 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 of the second direction clamping device 6 to pass through is opened on the side of the support plate 83 corresponding to the positioning platform 31, so that when the corresponding clamping opportunity occurs, the second driving component 62 drives the clamping block 61 through the through hole to press the frame 12.

[0069] The frame conveyor 7 includes a clamping jaw assembly 71 for gripping the frame 12 and a first moving assembly 72 for driving the clamping jaw assembly 71. The clamping jaw assembly 71 can grip the frame 12 at the front end of the device and move it above the positioning platform 31 via the first moving assembly 72. After that, it descends and releases the frame 12. In other words, the first moving assembly 72 includes two sets of actuators to achieve horizontal and vertical movement.

[0070] In this embodiment, multiple center plates 11 are arranged on the material belt 10 and are transported and pressed in the form of the material belt 10. Correspondingly, multiple groups of clamps, pre-pressing blocks 41, clamping blocks 91, positioning parts, fixed blocks 51, moving blocks, clamping blocks 61, etc. are provided to achieve high-speed automated assembly. Example 2

[0071] This embodiment provides a method for press-fitting a Type-C interface center plate 11 and a 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 platform 31 supports the center plate and the frame 12. The positioning member driving assembly 33 drives the positioning member to pass through the positioning platform 31 to position the center plate and the frame 12. The first-direction clamping device 5 is actuated to press the frame 12 against the center plate 11 in the first direction, and the second-direction clamping device 6 is actuated to press the frame 12 against the center plate 11 in the second direction; The pressing device 9 is actuated to press the center plate 11 and the frame 12 into one body.

[0072] Specifically, in combination with the structure of the assembly device in Example 1 and the steps of the above-mentioned press-fitting method, the method for assembling the center plate 11 and the frame 12 of the Type-C interface in this embodiment includes the following steps: Step 1: Feeding the center plate 11 The material belt 10 enters between the support plate 83 and the cover plate 84, and 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 on the edge of the material belt 10. The conveying driver 82 drives the driving wheel 81 to rotate and transports the material belt 10 forward to the top of the positioning device 3.

[0073] Step 2: Positioning When the material strip 10 is conveyed to the top 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.

[0074] As the positioning platform 31 is raised, the positioning member drive assembly 33 drives the positioning members (first insert 321, second insert 322, and third insert 323) to move upward, penetrate the positioning platform 31, and continue to rise above the center plate 11. The second insert 322 and the third insert 323 position and limit the center plate 11.

[0075] Step 3: First pre-compression The preloading drive assembly operates, and 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. It then moves downward to contact the center plate 11 and presses it down, pressing it tightly against the first flat surface 311 of the positioning platform 31. After the first preloading is completed, the preloading device 4 is reset.

[0076] Step 4: Place the border 12 The jaw assembly 71 grips the frame 12. The number of jaws and the number of frames 12 gripped equals the number of press-fit center panels 11 in a set, corresponding to the number of first flat surfaces 311 on the positioning platform 31. After the first moving assembly 72 drives the jaw assembly 71 horizontally to above the positioning platform 31, the jaw assembly 71 moves downward onto the positioning platform 31 and releases its jaws, placing the frame 12 on the second flat surface 312 of the positioning platform 31. The jaw assembly 71 then resets and awaits the next grasping operation.

[0077] Step 5: Second pre-pressing The preloading drive assembly operates, and 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. It then moves downward to contact the center plate 11 and the frame 12, pressing the center plate 11 tightly against the first plane 311 of the positioning platform 31 and the frame 12 tightly against the second plane 312 of the positioning platform 31. This causes the first insert 321 to be located on the outside of the frame 12, and the second insert 322 to be located between the side of the center plate 11 and the inside of the frame 12. The first insert 321, the second insert 322, and the third insert 323 achieve positioning and limiting of the frame 12 and the center plate 11. The preloading device 4 does not reset after the second preloading.

[0078] Step 6: The second direction clamping device 6 moves The second driving 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 , so as to press the frame 12 onto the center plate 11 .

[0079] Step 7: The first direction clamping device 5 moves In the first six steps, the first driver 55 always drives the top block 54 upward, and pushes the matching slope 562 of the moving block through the driving slope 561 of the top block 54. 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 platform 31.

[0080] After waiting for step 6 to complete, the first driver 55 drives the top block 54 to move downward. Through the resetting action of the elastic member 52 between the fixed and movable blocks, the distance between the two movable blocks is reduced, and the frame 12 is finally clamped on the center plate 11, thereby fixing the frame 12 in the X direction.

[0081] Step 8: Reset the pre-loading device 4 When the first direction clamping device 5 and the second direction clamping device 6 are in action, the pre-pressing block 41 always presses the frame 12 and the center plate 11. After the moving block clamps the frame 12, the pre-pressing block 41 separates from the center plate 11, and the pre-pressing device 4 is reset through the cooperation of the rotating wheel 421, the vertical drive mechanism and the horizontal drive mechanism.

[0082] Step 9: Detection The positioning device 3 and the frame 12 and the center plate 11 thereon are moved to the bottom of the detection device 2 by the second moving assembly 16 for detection to check whether the frame and the center plate are press-fitted into place.

[0083] Step 10: Press-fit During the inspection in step 9, the pressing device 9 moves along with it, and the second moving assembly 16 does not need to move again in step 10. The horizontal pressing actuator 94 pushes the pressing block 91 forward, and the vertical pressing actuator 93 drives the driving plate 92 and the sliding groove 921 thereon to move the driving plate 92 and the pressing block 91 downward, pressing the frame 12 and the center plate 11.

[0084] Step 11: The first direction clamping device 5 and the second direction clamping device 6 are reset and then operated again The pressing device 9 in step 10 is used to press 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 achieving clamping and fixing of the frame 12 and the center plate 11 in the three directions of X, Y and Z.

[0085] Step 12: Soldering 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 to the welding device 1 by the second moving assembly 16 to weld the frame 12 and the center plate 11. Multiple welding devices can be provided to weld multiple positions simultaneously.

[0086] Since the material strip 10 on the positioning table 31 has a plurality of center plates 11 , after each set of center plates 11 and frame 12 is welded, the second moving assembly 16 is driven to move and weld the next set of center plates 11 and frame 12 .

[0087] 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 the welding.

[0088] Step 13: Reset After all center panels 11 and frames 12 on positioning platform 31 are welded, pressing device 9 is reset, and pressing block 91 is disengaged from frame 12 and center panel 11. First-direction clamping device 5 and second-direction clamping device 6 are reset, and clamping block 61 and moving block are disengaged from frame 12 and center panel 11. The positioning member in positioning device 3 moves downward, disengaging from frame 12 and center panel 11. The material strip 10 is transported backward via drive wheel 81 and conveyor drive 82.

[0089] The pressing device 9 , the first direction clamping device 5 , the second direction clamping device 6 , and the positioning device 3 are moved toward the pre-pressing device 4 by the second moving assembly 16 to perform the next cycle.

[0090] The press-fitting device for the Type-C interface center plate 11 and frame 12 of this embodiment supports the center plate 11 and frame 12 via a positioning platform 31. A positioning member driving assembly 33 drives the positioning member through the positioning platform 31 to position the center plate 11 and frame 12. Simultaneously, a first-direction clamping device 5 and a second-direction clamping device 6 respectively press the frame 12 against the center plate 11 in the first and second directions. This achieves multi-directional position fixation between the center plate 11 and frame 12 for multiple products, ensuring assembly accuracy between the center plate 11 and the U-shaped frame. Finally, a pressing device 9 presses the center plate 11 and frame 12 together and maintains the pressed state for welding. This achieves automatic, highly stable, high-precision, and efficient press-fitting and welding of the center plate 11 and frame 12. This solves the problems of unstable dimensional accuracy, low yield, and slow welding speed in the assembly and welding of the Type-C interface center plate 11 and frame 12.
