Description

Technical Field

[0001] This invention relates to the field of automated assembly and welding, and more specifically, to a high-definition connector assembly and welding mechanism. Background Technology

[0002] In the automated production of ultra-high-definition connectors, multiple components (such as the lower housing and upper cover) need to be positioned, assembled, and connected and fixed using lasers and other means.

[0003] Currently, in the automated production of ultra-high-definition connectors, fixtures are typically used in conjunction with general clamping structures. However, existing technologies for welding these products (such as the lower housing, upper housing, and internal wire binding structures) are prone to thermal deformation due to the thin-walled nature of the components and the localized high temperatures during welding. Existing equipment often relies solely on a single top clamping block for clamping, lacking lateral restraint on the housing and failing to effectively position internal details such as curved clamps. This results in product displacement or deformation during welding, impacting final assembly accuracy and yield. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a high-definition connector joint assembly and welding mechanism.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0007] Furthermore, a first pressure plate is fixedly connected to the inner wall of the hollow groove, and the first pressure plate has multiple first welding point grooves corresponding to the welding area of ​​the material.

[0008] Furthermore, the lower end of the first pressure plate is provided with a plurality of weld side limiting support components for constraining the lateral thermal deformation of the material. The weld side limiting support components include a first movable groove opened at the lower end of the first pressure plate, a slider slidably connected in the first movable groove, a side support piece fixed to the lower end of the slider, a chamfer opened at the lower end of the side support piece, and a second spring between the slider and the inner wall of the first movable groove.

[0009] Furthermore, the lower end of the pressure block is symmetrically provided with two side support inserts for constraining the tail clamps of the material. The side support inserts include an insert plate fixed to the lower end of the pressure block, a movable plate movably inserted inside the insert plate and extending out of the insert plate, a second pressure plate rotatably connected to one side of the insert plate, a hinge seat fixed to the upper end of the movable plate, a connecting plate with one end rotatably connected to the hinge seat and the other end rotatably connected to the second pressure plate, and a reset component disposed inside the insert plate for driving the movable plate to reset.

[0010] Furthermore, the reset component includes two movable blocks fixed on both sides of the movable plate and slidably connected inside the insert plate, two guide rods symmetrically fixed inside the insert plate, and two third springs respectively sleeved on the outside of the two guide rods and connected at both ends to the inner wall of the insert plate and the movable blocks, with the two movable blocks respectively movably sleeved on the outside of the two guide rods.

[0011] Furthermore, the pre-pressing positioning component includes a first bracket fixed to the upper end of the transfer machine platform, a first pressing part disposed on one side of the first bracket, and a positioning part disposed on the other side of the first bracket.

[0012] Furthermore, the rear cover cutting assembly includes a feeding section fixed to the upper end of the conveyor platform, an upper iron shell cutting section disposed on one side of the feeding section, and a transport assembly section disposed on one side of the upper iron shell cutting section.

[0013] Furthermore, the first detection component includes a first camera fixed to the upper end of the transfer machine platform and a second pressing part disposed on one side of the first camera.

[0014] Furthermore, the hot riveting part includes a three-axis moving module fixed to the upper end of the transfer machine platform and a hot melt welding part fixed to the moving end of the three-axis moving module.

[0015] Furthermore, the second detection component includes a frame fixed to the upper end of the transfer machine platform, a second single-axis moving module fixed to one side of the frame, and a second camera fixed to the moving end of the second single-axis moving module.

[0019] (3) By using the side support plug at the lower end of the pressure block, when the pressure block presses the upper cover shell, the side support plug can synchronously drive the second pressure plate to apply pressure to the line body hoop, thereby effectively constraining the tail structure of the product and ensuring that the hoop maintains an ideal tightening position when welding with the upper cover shell, thus reducing the welding defect rate.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 17 A high-definition connector assembly and welding mechanism includes a transfer machine 1, a pre-pressure positioning component 2, a rear cover cutting component 3, a first detection component 4, multiple laser welding components 5, a hot riveting part 6, a second detection component 7, a transfer component 8, and a fixture body 9. A lower housing 92 and an upper cover 93 located on the lower housing 92 are placed on the fixture body 9. Second welding grooves 91 are provided on both sides of the fixture body 9. The second welding grooves 91 facilitate the passage of laser light to weld the connection points between the lower housing 92 and the upper cover 93.

[0024] Multiple laser welding components 5 are used to weld the upper end and left and right sides of the material on the fixture body 9 respectively. The laser welding component 5 includes a second bracket 51 fixed to the upper end of the transfer machine table 1, a laser head 52 fixed to the second bracket 51, and a fixture flipping part 53 disposed on one side of the second bracket 51.

[0025] The jig flipping part 53 includes a first single-axis moving module 531 fixed to one side of the second bracket 51, a flipping module 532 fixed to the moving end of the first single-axis moving module 531, a frame plate 533 fixed to the flipping part of the flipping module 532, two first cylinders 534 symmetrically fixed to one side of the frame plate 533, two clamping arms 535 symmetrically slidable to one side of the frame plate 533 and respectively connected to the telescopic ends of the two first cylinders 534, a second cylinder 536 fixed to the frame plate 533, a pressure seat 537 connected to the lower telescopic end of the second cylinder 536, a pressure block 538 slidable to one side of the pressure seat 537, a first spring 539 with one end connected to the upper end of the pressure block 538 and the other end connected to the side wall of the pressure seat 537, and a hollow groove 540 opened at the lower end of the pressure block 538.

[0026] When the fixture body 9 moves below the second support 51, the first single-axis moving module 531 operates, driving the flipping module 532, the frame plate 533, and the structure mounted on the frame plate 533 to move downwards. The two first cylinders 534 retract and drive the two clamping arms 535 to move towards each other, clamping the fixture body 9. Then, the second cylinder 536 is controlled to operate, driving the pressure seat 537 to move downwards, so that the lower end of the pressure block 538 can press against the upper surface of the upper cover shell 93. The first spring 539 applies a pushing force to the pressure block 538, pressing the pressure block 538 against the upper surface of the upper cover shell 93, completing the positioning of the lower shell 92 and the upper cover shell 93, preventing displacement during welding, lifting, and flipping movements. Subsequently, the first single-axis moving module 531 works to drive the fixture body 9 to rise, and the flipping module 532 works to drive the frame plate 533 and the fixture body 9 to rotate, so that the fixture body 9 changes from a horizontal state to an inclined state. At this time, the laser output by the laser head 52 passes through the second welding point groove 91 to weld the connection between the upper cover shell 93 and the lower shell 92.

[0027] The welding at the connection points of the upper cover shell 93 and the lower shell 92 on the left and right sides is completed by two independently set laser welding components 5. That is, the left side is welded first by one laser welding component 5, and then the right side is welded by the other laser welding component 5. After the welding of the left and right sides is completed, the front welding is performed by the last laser welding component 5. That is, when the last laser welding component 5 is welding, the flipping module 532 does not need to drive the frame plate 533 and the fixture body 9 to flip. The laser output by the laser head 52 can directly act on the upper end of the upper cover shell 93 through the hollow groove 540, and weld the connection point of the upper cover shell 93 and the lower shell 92 from the front.

[0028] like Figure 8 and Figure 9 As shown, a first pressure plate 541 is fixed to the inner wall of the hollow groove 540, and multiple first welding point grooves 542 are formed on the first pressure plate 541. When the lower end of the pressure block 538 presses on the upper cover shell 93, the lower end of the first pressure plate 541 can also press on the upper cover shell 93. The positions of the first welding point grooves 542 correspond to the welding area between the upper cover shell 93 and the lower shell 92. This design can provide stable pressure on the welding area of ​​the upper cover shell 93 through the first pressure plate 541, ensuring the stability of the upper cover shell 93 during the welding process and restraining the thermal deformation of the upper cover shell 93 caused by the temperature rise during the welding process.

[0029] like Figures 11 to 13 , Figures 18 to 20As shown, a plurality of welding side limiting support assemblies 55 are provided at the lower end of the first pressure plate 541. Each welding side limiting support assembly 55 includes a first movable groove 551 opened at the lower end of the first pressure plate 541, a slider 552 slidably connected in the first movable groove 551, a side support piece 553 fixed to the lower end of the slider 552, a chamfer 555 opened at the lower end of the side support piece 553, and a second spring 554 provided in the first movable groove 551. The two ends of the second spring 554 are respectively connected to one side of the slider 552 and the inner wall of the first movable groove 551.

[0030] like Figure 18 and Figure 20 As shown, two vertically erected plate-like structures 921 are provided on both sides of the lower housing 92. The upper end of the plate-like structure 921 is flush with the upper end of the upper cover shell 93 assembled on the lower housing 92, and there are weld points at the connection between the upper end of the plate-like structure 921 and the upper end of the upper cover shell 93 (weld points are present on the front and both sides). Figure 11 As shown, when the lower housing 92 is placed on the fixture body 9, the height of the fixture body 9 limiting the lower housing 92 cannot completely cover the height of the entire plate structure 921. Due to the setting of the first pressure plate 541, the upper end of the weld between the upper end of the plate structure 921 and the upper end of the upper cover 93 can be constrained by the first pressure plate 541 to prevent deformation during the welding process.

[0031] As the first pressure plate 541 descends and is about to press against the upper end of the upper cover shell 93, the chamfer 555 at the lower end of the side support piece 553 first contacts the upper end of the plate structure 921. Subsequently, the plate structure 921 applies a force to the side support piece 553, pushing the side support piece 553 and the slider 552 to move. The slider 552 slides in the first movable groove 551 and applies a force to the second spring 554, causing the second spring 554 to store energy. After the first pressure plate 541 presses against the upper end of the upper cover shell 93, one side of the side support piece 553 will contact the outer edge of the plate structure 921. When in side contact, the second spring 554 can apply a force to the slider 552. This force is transmitted to the plate structure 921 through the slider 552 and the side support plate 553, thus becoming a constraint force applied to the side of the plate structure 921. Through the design of the second spring 554, the side support plate 553 and the slider 552, the side of the weld between the upper end of the plate structure 921 and the upper end of the upper cover shell 93 can be constrained, improving the stability during the welding process and reducing the deformation rate of the weld between the plate structure 921 and the upper cover shell 93 during the welding process.

[0032] like Figures 14 to 18As shown, two side support plugs 56 are symmetrically arranged at the lower end of the pressure block 538. The side support plugs 56 include a plug plate 561 fixed to the lower end of the pressure block 538, a movable plate 562 movably inserted into the plug plate 561 and extending from the lower end of the plug plate 561, a second pressure plate 563 rotatably connected to the lower part of the outer wall of the plug plate 561 at its bottom end, a hinge seat 564 fixed to the upper end of the movable plate 562, a connecting plate 565 whose two ends are respectively rotatably connected to the hinge seat 564 and the middle part of the second pressure plate 563, and a reset member disposed inside the plug plate 561 for driving the movable plate 562 to reset.

[0033] The lower end of the movable plate 562 extends from the lower end of the insert plate 561, and the lower end of the second pressure plate 563 is rotatably connected to one side of the insert plate 561.

[0034] like Figure 18 As shown, the lower housing 92 has two arc-shaped clamps 922 at its tail for tightening the wire. The free ends of these two arc-shaped clamps 922 need to be welded together simultaneously when welding the upper housing 93 to the front, so that the upper housing 93 can be connected to the two arc-shaped clamps 922 (see...). Figure 16 To ensure the two arc-shaped clamping plates 922 maintain their binding effect on the wire body during welding, when the pressure block 538 is pressed against the upper cover shell 93, the two insert plates 561 at the lower end of the pressure block 538 can be inserted into the gap between the inner wall of the fixture body 9 and the two arc-shaped clamping plates 922. During the insertion process, the lower end of the movable plate 562 extending from the lower end of the insert plate 561 contacts the inner bottom wall of the fixture body 9. The bottom end of the movable plate 562 first abuts against the inner bottom surface of the fixture body 9 and is pushed upward relative to it. The hinge seat 564 rises accordingly and pulls / pushes the second pressure plate 563 around the hinge axis at its bottom through the connecting plate 565, thereby making the pressing surface of the second pressure plate 563 close to and hold the arc-shaped clamping plate 922, realizing accurate lateral positioning and constraint of the thin-walled clamping plate before welding. This ensures its stability during the welding process with the upper cover shell 93 and avoids deformation.

[0035] like Figure 17As shown, the reset component includes two movable blocks 568 fixed on both sides of the movable plate 562 and slidably connected inside the insert plate 561, two guide rods 566 symmetrically fixed inside the insert plate 561, and two third springs 567 respectively sleeved on the outside of the two guide rods 566. The two movable blocks 568 are respectively movably sleeved on the outside of the two guide rods 566. The two ends of the third springs 567 are respectively connected to the inner wall of the insert plate 561 and the movable blocks 568. When the movable plate 562 moves upward inside the insert plate 561, the movable blocks 568 move with the movable plate 562 and squeeze the third springs 567. The third springs 567 store energy. When the insert plate 561 is pulled out from the gap between the inner wall of the fixture body 9 and the two arc-shaped clamps 922, the third springs 567 apply a force to the movable blocks 568, pushing the movable blocks 568 and the movable plate 562 downward, so that the lower end of the movable plate 562 extends out from the lower end of the insert plate 561 and resets, waiting for the next constraint action.

[0036] like Figure 1 and Figure 2 As shown, the pre-pressing positioning assembly 2 includes a first bracket 21 fixed to the upper end of the transfer machine table 1, a first pressing part 22 disposed on one side of the first bracket 21, and a positioning part 23 disposed on the other side of the first bracket 21. Both the first pressing part 22 and the positioning part 23 use a universal cylinder to extend and retract to drive the pressing head to move. When the fixture body 9 moves on the transfer machine table 1 to the position of the first bracket 21, the universal cylinder drives the pressing head to move and press it onto the lower housing 92, thereby performing pre-pressing positioning.

[0037] like Figure 1 and Figure 3 As shown, the back cover cutting assembly 3 includes a feeding section 31 fixed to the upper end of the transfer table 1, an upper iron shell cutting section 32, and a transport assembly section 33. The feeding section 31 is equipped with a material roll, which can feed the material roll so that the material strip can enter the upper iron shell cutting section 32. The upper iron shell cutting section 32 consists of upper and lower molds, a cutter set in the molds, and a universal cylinder that drives the cutter to rise and fall. The material strip passes between the upper and lower molds, and the universal cylinder drives the cutter to fall and cut the upper cover 93 on the material strip. The transport assembly section 33 includes a multi-axis motion platform and a suction cup mounted on the multi-axis motion platform. By adjusting the position of the suction cup, the suction cup can pick up the cut upper cover 93, and then transport the upper cover 93 to the top of the fixture body 9. The suction cup falls and mounts the upper cover 93 above the lower housing 92 inside the fixture body 9, completing the assembly operation.

[0038] like Figure 1 and Figure 3As shown, the first detection component 4 includes a first camera 41 and a second pressing part 42 fixed on the upper end of the transfer table 1. The first camera 41 is a CCD camera used to detect the material on the fixture body 9 transferred from the rear cover cutting component 3, and to detect whether the assembly position of the lower shell 92 and the upper cover 93 on the fixture body 9 is correct. The second pressing part 42 is a universal cylinder and a pressing part installed on the telescopic end of the universal cylinder. When the fixture body 9 is transferred to the area below the second pressing part 42, the universal cylinder extends to drive the pressing part to descend and press on the upper cover 93, completing the secondary pressing assembly of the upper cover 93 and the lower shell 92.

[0039] like Figure 1 , Figure 5 and Figure 6 As shown, the hot riveting part 6 includes a three-axis moving module 61 fixed on the upper end of the transfer machine table 1 and a hot melt welding part 62 fixed on the moving end of the three-axis moving module 61. After the fixture body 9 is laser welded by the laser welding assembly 5, it moves to the bottom of the hot melt welding part 62. The three-axis moving module 61 drives the hot melt welding part 62 to move, and the hot melt welding part 62 performs supplementary hot melt welding on the upper cover shell 93.

[0040] The second inspection component 7 includes a frame 71 fixed to the upper end of the transfer table 1, a second single-axis moving module 72 fixed to one side of the frame 71, and a second camera 73 fixed to the moving end of the second single-axis moving module 72. The second camera 73 is also a CCD camera. When the fixture body 9 flows from the hot riveting part 6 to the second inspection component 7 process, the second camera 73 can inspect the hot riveting weld points and laser weld points on the upper surface of the upper cover shell 93. After being inspected by the second inspection component 7, the fixture body 9 flows to the underside of the transfer component 8. The transfer component 8 consists of a multi-axis motion platform and a robot. If the second inspection component 7 detects that the welding is unqualified, the transfer component 8 can clamp the fixture body 9 and place it on the NG (unqualified) conveyor belt; if the second inspection component 7 detects that the welding is qualified, it is directly removed from under the transfer component 8 and enters the next process.

[0041] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
