Description

Technical Field

[0001] The utility model belongs to the technical field of mobile phone frame welding, and particularly relates to a welding automatic assembly device. Background Art

[0002] See Figure 1 As shown, due to the manufacturing process requirements of the mobile phone frame blank, two alloy extrusion materials (titanium-aluminum alloy) long strip materials 11 and square small parts 12 (BOSS columns) need to be fixed in a carrier 13 at specified positions and loaded into a laser welding machine for welding. This method can minimize the production difficulty of the extrusion materials, improve the overall straightness and flatness requirements, and reduce the blank production cost.

[0003] The existing carrier 13 is as Figure 1 shown. It includes a base 131 and a pressing cover 132. Placement grooves 1311 are correspondingly opened on the base 131 according to the sizes and shapes of the long strip material 11 and the small parts 12. In order to facilitate the pressing cover 132 to be covered on the base 131, positioning pins 133 are vertically embedded on the base 131, and positioning holes 1321 are correspondingly opened on the pressing cover 132. In order to squeeze and fix the long strip material 11 and the small parts 12 in the placement grooves 1311, a handle 134 is provided on the base 131. Rotating the handle 134 can drive the corresponding linkage mechanism to squeeze and fix the long strip material 11 and the small parts 12. In order to fix the pressing cover 132 when the pressing cover 132 is covered on the base 131, eccentric locking mechanisms 135 of the existing structure are rotatably connected to both sides of the base 131. After the eccentric locking mechanisms 135 are flipped, the pressing cover 132 can be pressed to fix it on the base 131 and press the blank.

[0004] During the existing production process, it is necessary for workers to separately place the long strip material 11 and the small parts 12 in the placement grooves 1311, rotate the handle 134 to squeeze the blank, then place the pressing cover 132, flip the handle 1351 of the eccentric locking mechanism 135, and then send it to the welding equipment for welding. In this process, a large amount of manpower is required, the labor intensity is high, and the work efficiency is low, which is not suitable for large-scale assembly and welding requirements. Based on this, it is urgent to design an automated assembly device that integrates the above assembly processes. Summary of the Utility Model

The corresponding working stations of the above devices on the circulating conveyor device 3 are as follows: the feeding device 4 corresponds to the long strip material feeding station and the small part feeding station, the material tightening device 51 corresponds to the material tightening station, the upper cover device 61 corresponds to the upper cover station, the gland pressing device 71 corresponds to the gland pressing station, the vision inspection device 9 corresponds to the vision inspection station, the gland loosening device 72 corresponds to the gland loosening station, the lower cover device 62 and the gland brushing device 63 correspond to the lower cover station, the material loosening device 52 corresponds to the material feeding station, the discharging device 81 corresponds to the discharging station, the carrier brushing device 82 corresponds to the carrier brushing station. In addition, a robot picking and placing station is also arranged between the vision inspection station and the gland loosening station.

[0061] See Figure 4 、 5 、6, the circulating conveyor device 3 includes an annular track circulating line 32 of an existing structure driven by a driving motor 31 and a plurality of bottom plates 33 driven by the annular track circulating line 32. The bottom plate 33 includes a transfer plate 331 circulating and conveying on the annular track circulating line 32 and a carrier placing plate 332 fixedly connected to the transfer plate 331 by bolts. The base 131 and the gland 132 can be placed left and right on each carrier placing plate 332. In order to position the base 131 and the gland 132, both the base 131 and the gland 132 can be positioned on the carrier placing plate 332 through a positioning pin shaft structure.

[0062] In this embodiment, 12 bottom plates 33 are correspondingly arranged on the annular track circulation line 32 corresponding to the above-mentioned workstations, and can accurately circulate and stay at each workstation. In order to ensure the repeatability of the circulation position of each bottom plate 33 at each workstation, positioning grooves 3311 are opened on the outer sides of each transfer plate 331. Positioning cylinders 34 are hinge-connected to the corresponding positions of the frame 2. A rotating shaft 35 is rotatably connected to the frame 2. A positioning block 36 is fixedly connected to the rotating shaft 35. The guide rod of the positioning cylinder 34 is hinge-connected to the positioning block 36. When the guide rod of the positioning cylinder 34 extends, it can drive the positioning block 36 to flip so that the positioning block 36 is clamped in the positioning groove 3311.

[0063] See Figure 7 As shown, the feeding device 4 includes a magazine 41 for stacking and placing the long strips 11, a lifting mechanism 42 for lifting the long strips 11 in the magazine 41, a long strip feeding device 43 for sucking the long strips 11 in the magazine 41 and transporting them to the placement groove 1311 of the corresponding base 131, a vibrating disk alignment device 44 for aligning and outputting the small parts 12, and a small part feeding device 45 for sucking the aligned small parts 12 and transporting them to the placement groove 1311 of the corresponding base 131. The vibrating disk alignment device 44 is a prior art and will not be elaborated here.

[0064] See Figure 8 As shown, in this embodiment, the magazine 41 is a long strip-shaped double magazine structure. After one magazine is used up, the spare magazine can be directly rotated for use. After the empty magazine rotates out, it is convenient for manual filling. Therefore, the magazine 41 includes a magazine mounting plate 411, a magazine one 412 and a magazine two 413 vertically and fixedly mounted on the magazine mounting plate 411, and a magazine motor 414 fixedly mounted on the frame 2 below the magazine mounting plate 411. The output shaft of the magazine motor 414 can drive the magazine mounting plate 411 to rotate, thereby driving the magazine one 412 and the magazine two 413 to rotate.

[0065] In order to keep the uppermost long strip 11 in the magazine 41 at the same height all the time, the lifting mechanism 42 includes a lifting linear module 421 vertically and fixedly mounted on the frame 2, and a top rod 422 vertically and fixedly mounted on the moving part of the lifting linear module 421. The top rod 422 can slide through the magazine mounting plate 411 and selectively extend into the magazine one 412 and the magazine two 413 during feeding. Driven by the lifting linear module 421, the top rod 422 can lift the long strip 11.

[0066] See Figure 9As shown in the figure, the long-strip feeding device 43 includes a long-strip feeding bracket 431 fixedly connected to the frame 2 by bolts, a long-strip feeding rodless cylinder 432 horizontally fixed on the long-strip feeding bracket 431, a long-strip feeding pressing cylinder 433 vertically fixedly connected to the moving part of the long-strip feeding rodless cylinder 432, a long-strip feeding plate 434 fixedly connected to the guide rod of the long-strip feeding pressing cylinder 433, and a plurality of long-strip feeding suction nozzles 435 vertically fixedly embedded on the long-strip feeding plate 434. The long-strip feeding pressing cylinder 433 drives the long-strip feeding suction nozzles 435 to move up and down. The long-strip feeding suction nozzles 435 adsorb two long-strip materials 11 in the material bin 41 through a pneumatic suction device. The long-strip feeding rodless cylinder 432 transfers the long-strip materials 11 to the placement groove 1311 of the base 131 staying at the long-strip material feeding station.

[0067] See Figure 10 As shown in the figure, the small-piece feeding device 45 includes a small-piece feeding bracket 451 fixedly connected to the frame 2, a feeding linear module 452 horizontally arranged on the small-piece feeding bracket 451, and a feeding cylinder 453 vertically fixedly connected to the moving part of the feeding linear module 452. A feeding frame 454 is fixedly installed on the guide rod of the feeding cylinder 453. Since in this embodiment, two groups of long-strip materials 11 and small-piece materials 12 are placed in each carrier 13, accordingly, a feeding rotary cylinder 455 is horizontally fixedly installed on the feeding frame 454 by bolts. A variable pitch mechanism 457 is arranged on the guide rod of the feeding rotary cylinder 455, and a small-piece feeding suction nozzle 456 is fixedly connected to the moving part of the variable pitch mechanism. By setting the variable pitch mechanism, it is adapted to the different distances between the small-piece materials 12 in the placement groove 1311 and the distances between the small-piece materials 12 sorted by the vibrating disk alignment device 44.

[0068] See Figure 11 As shown in the figure, in this embodiment, the variable pitch mechanism 457 includes a variable pitch connecting plate 4571 fixedly installed on the rotating part of the feeding rotary cylinder 455, a variable pitch cylinder 4572 fixedly installed on the variable pitch connecting plate 4571, a variable pitch block 4573 horizontally slid on the lower part of the variable pitch connecting plate 4571, a guide post 4574 fixedly connected to the upper end of the variable pitch block 4573, a variable pitch plate 4575 vertically fixedly connected to the guide rod of the variable pitch cylinder 4572, and a variable pitch chute 4576 obliquely opened on the variable pitch plate 4575. The guide post 4574 can slidably penetrate through the variable pitch chute 4576. Thus, through the above structure, when the guide rod of the variable pitch cylinder 4572 extends and retracts, it can drive the two variable pitch blocks 4573 on both sides to slide left and right. Of course, other existing technologies can be selected for the variable pitch mechanism.

[0069] See Figure 12As shown in the figure, the material clamping device 51 is used to rotate the handle 134 to clamp the long strip material 11 and the small part material 12. Specifically, the material clamping device 51 includes a material clamping bracket 511 fixedly connected to the frame 2, a material clamping cylinder 512 vertically and fixedly connected to the material clamping bracket 511, a material clamping plate 513 fixedly connected to the guide rod of the material clamping cylinder 512, two obliquely arranged material clamping rotary cylinders 514 fixedly connected to the material clamping plate 513, and a rotary sleeve 515 arranged on the rotating part of the material clamping rotary cylinder 514. The rotary sleeve 515 can be sleeved on the handle 134. When the material clamping rotary cylinder 514 drives the rotary sleeve 515 to rotate, the rotary sleeve 515 can drive the handle 134 to rotate, so as to lock the long strip material 11 and the small part material 12 in the placement groove 1311.

[0070] See Figure 13 As shown in the figure, the upper cover device 61 is used to clamp the gland 312 and transfer it to the base 131. Specifically, the upper cover device 61 includes an upper cover bracket 611 fixedly connected to the frame 2, an upper cover side-shifting cylinder 612 horizontally and fixedly connected to the upper cover bracket 611, an upper cover pressing cylinder 613 vertically and fixedly connected to the guide rod of the upper cover side-shifting cylinder 612, an upper cover plate 614 fixedly connected to the guide rod of the upper cover pressing cylinder 613, two upper cover clamping cylinders 615 arranged back to back on the upper cover plate 614, and upper cover claws 616 fixedly connected to the guide rods of the two upper cover clamping cylinders 615. The upper cover side-shifting cylinder 612 can drive the upper cover clamping cylinder 615 to move horizontally, the upper cover pressing cylinder 613 can drive the upper cover clamping cylinder 615 to move longitudinally, and the upper cover clamping cylinder 615 can drive the upper cover claws 616 to move relatively to clamp the gland 312.

[0071] See Figure 14 、 15 As shown in Figures 16 and 17, the gland device 71 is used to lock the gland on the base 131 and includes a lifting handle mechanism for lifting the handle 1351 and a rotating handle mechanism for rotating the handle 1325. Specifically, the gland device 71 includes a gland bracket 711 fixedly connected to the frame 2, and a lifting handle mechanism and a rotating handle mechanism arranged on the gland bracket 711.

[0072] The lifting handle mechanism includes a gland pressing cylinder 712 vertically and fixedly connected to the upper end of the gland support 711, a lifting plate 7121 vertically and fixedly connected to the guide rod of the gland pressing cylinder 712, two lifting and rotating cylinders 713 relatively fixed on the lifting plate 7121, a connecting rod 7131 fixedly connected to the rotating member of the lifting and rotating cylinder 713, and a clamping assembly 714 rotatably connected to the connecting rod 7131 for clamping the handle. The clamping assembly 714 includes a slide rail 7141 rotatably connected to the connecting rod 7131, a slider 7142 vertically and fixedly connected to the guide plate 7122. The slide rail 7141 is slidably inserted through the slider 7142. A clamping plate 7143 is fixedly connected to the slide rail 7141. A clamping and pressing cylinder 7144 is vertically and fixedly connected to the upper part of the clamping plate 7143. A sliding column 7145 is arranged on the guide rod of the clamping and pressing cylinder 7144. Clamping blocks 7146 are relatively horizontally slid on the lower part of the clamping plate 7143. An obliquely crossed cross plate 7147 is integrally and fixedly connected to the upper ends of the two clamping blocks 7146. A cross through groove 7148 is formed along the length of the cross plate 7147. The sliding column 7145 is slidably inserted through the cross through grooves 7148 of the two cross plates 7147. Thus, the telescopic movement of the guide rod of the clamping and pressing cylinder 7144 can drive the clamping blocks 7146 to move towards or away from each other, so as to clamp and release the handle 3151. Of course, the clamping assembly 714 can select an existing clamping cylinder structure and corresponding jaws to realize the clamping of the handle 3151.

[0073] In order to support the connecting rod 7131 when it rotates, a guide plate 7122 is vertically and fixedly connected to the lifting plate 7121. An arc through groove 7123 is formed on the guide plate 7122. The connecting rod 7131 is slidably inserted through the arc through groove 7123. Thus, through the above structure, the lifting and rotating cylinder 713 drives the connecting rod 7131 to rotate, thereby driving the two clamping assemblies to move towards each other, and further realizing the lifting of the handle 1351.
