[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form.

[0035] Embodiment 1, as Figures 1 to 9 As shown, the semi-automatic ultrasonic seam welding machine described in the present application includes a support frame 11, at the bottom of the support frame 11 is provided with an equipment part 12 for providing external power supply and power control, at the top of the equipment part 12 is installed a base plate 10, on the base plate 10 is vertically stacked bottom mold device 8 and seam welding device 9.

[0036] The difference from the prior art is that a slide plate device 13 is provided on the bottom plate 10 for carrying the tab 17 and the base material 16 and reciprocating the two in the horizontal direction to between the bottom mold device 8 and the roll welding device 9 in the vertical direction for the roll welding operation;

[0037] The skateboard device 13 comprises a skateboard bracket 14 mounted and fixed on the bottom plate 10, and a sliding plate 1 is arranged on the skateboard bracket 14 and reciprocates in the horizontal direction through the driving device 7;

[0038] Two sets of first positioning ribs 2-1 and second positioning ribs 2-2 with the same structure and symmetrically arranged along the longitudinal center line of the sliding plate 1 are arranged in the longitudinal direction of the sliding plate 1, and a base material placement plate 19 for placing the base material 16 and a tab placement plate 18 for placing the tab 17 are arranged between the first positioning ribs 2-1 and the second positioning ribs 2-2 in the transverse direction, as well as two sets of front positioning members 20 arranged opposite to each other;

[0039] The first positioning rib 2-1 is used to provide manual positioning of the pole lug 17 along the longitudinal direction when the first pole lug 17 is welded on one side of the base material 16; the second positioning rib 2-2 is used to provide manual positioning of the base material 16 along the longitudinal direction when the second pole lug 17 is welded on the other side of the base material 16;

[0040] The first positioning rib 2-1 is provided with movable pressure plates 4 and clamping devices 5 for vertically positioning and pressing the pole ear 17, and movable baffles 3 and base material pressure plate devices 6 for horizontally and longitudinally positioning and vertically pressing the base material 16 on its two lateral sides.

[0041] The first positioning rib 2-1 includes a first tab baffle 2-11 arranged in the longitudinal direction and used to position the longitudinal edge of the parent material 16 when placing the parent material 16. The first tab baffle 2-11 is used to cooperate with the movable baffle 3 and the movable pressure plate 4 to position the parent material 16 and the tab 17.

[0042] The longitudinal ends of the first tab baffle 2-11 are respectively fixedly connected to a group of baffle fixing edges 2-12, and the outer side edges of each group of baffle fixing edges 2-12 abut against the inner side edges of a group of positioning baffles 2-14 fixedly mounted on the sliding plate 1;

[0043] A set of adjustment blocks 2-13 are respectively arranged on both lateral sides of each set of baffle fixing edges 2-12, and each set of adjustment blocks 2-13 is connected with a set of adjustment screws and nuts 2-14 through internal and external threads;

[0044] The above-mentioned first positioning rib 2-1 has a lateral position adjustment function. The two groups of adjustment blocks 2-13 arranged on the lateral sides of the baffle fixing edge 2-12 enable the first positioning rib 2-1 to have a position adjustment range in two directions in the lateral direction, thereby adjusting the lateral spacing between the first positioning rib 2-1 and the second positioning rib 2-2, thereby realizing the roll welding processing and preparation of at least two groups of base materials 16 and pole ears 17 of specified sizes.

[0045] Specifically, when producing plates of the same specification and size, the first positioning rib 2-1 and the second positioning rib 2-2 are fixed and kept at a constant distance to ensure that the width of the plate after welding the parent material 16 and the tab 17 are the same, and maintain good consistency;

[0046] When it is necessary to replace the production of plates of different specifications, according to the actual situation of size processing or reduction, select a group of adjustment blocks 2-13 on the lateral side of the baffle fixing edge 2-12, and rotate the screws of the adjusting screw and nut group 2-14 to push the baffle fixing edge 2-12 to slide along the inner side of the positioning baffle 2-14, thereby driving the first pole ear baffle 2-11 to slide from one side to the other in the lateral direction; during the adjustment process, the positioning baffle 2-14 provides guidance and regulation of the sliding trajectory in the lateral direction, thereby ensuring that the adjusted first pole ear baffle 2-11 always remains parallel to the welding head 9-1 of the rolling welding device 9.

[0047] Furthermore, in order to facilitate the operator to observe the accuracy of the first tab baffle 2-11 in locating the tab 17, a plurality of concave first through grooves 2-16 are provided on the inner side of the first tab baffle 2-11. When the outer side of the tab 17 abuts against the inner side of the first tab baffle 2-11, the operator can observe whether the above positioning of the two is accurate through the first through grooves 2-16.

[0048] The second positioning rib 2-2 includes a second tab baffle 2-21 arranged in the longitudinal direction and used to position the longitudinal edge of the parent material 16 when placing the parent material 16;

[0049] The longitudinal ends of the second tab baffle 2-21 are respectively fixedly connected to a group of baffle fixing edges 2-12, and the outer side of each group of baffle fixing edges 2-12 abuts against the inner side edge of a group of positioning baffles 2-14 fixedly mounted on the sliding plate 1;

[0050] A set of adjustment blocks 2-13 are respectively arranged on both lateral sides of each set of baffle fixing edges 2-12, and each set of adjustment blocks 2-13 is connected with a set of adjustment screws and nuts 2-14 through internal and external threads;

[0051] The second positioning baffle 2-2 has the same lateral position adjustment means as the above-mentioned first positioning baffle 2-1. Specifically, according to the actual situation of size processing or reduction, a group of adjustment blocks 2-13 are selected on the lateral side of the baffle fixing edge 2-12. By rotating the screws of the adjusting screw and nut group 2-14, the baffle fixing edge 2-12 is pushed to slide along the inner side edge of the positioning baffle 2-14, thereby driving the second pole ear baffle 2-21 to slide from one side to the other in the lateral direction.

[0052] Furthermore, in order to facilitate the operator to observe the accuracy of the second tab baffle 2-21 positioning the base material 16, a concave second through groove 2-26 is provided on the inner side of the second tab baffle 2-21. When the outer side of the base material 16 abuts against the inner side of the second tab baffle 2-21, the operator can observe whether the positioning of the two is accurate through the second through groove 2-26, and then perform the roll welding operation of the second tab 17 and the base material 16.

[0056] Furthermore, an array of guide shafts 6-4 is fixedly arranged on the sliding plate 1, and each group of guide shafts 6-4 is vertically connected to the mounting frame 6-1 and the mother material pressure plate 6-3; when the rotating compression screw and nut group 6-2 is used to vertically drive the mother material pressure plate 6-3, the guide shaft 6-4 provides auxiliary guidance during the lifting and lowering process of the mother material pressure plate 6-3.

[0057] On the inner side of the first positioning rib 2-1, the movable baffle 3 and the base material pressing plate device 6 cooperate to implement the positioning and pressing and fixing of the base material 16. Specifically, firstly, according to the specifications and dimensions of the produced plate, a suitable movable baffle 3 is selected and placed on the pole ear plate 18, and the position of the movable baffle 3 is adjusted so that its outer side in the horizontal direction is against the inner side of the first pole ear baffle 2-11; then, the base material 16 is placed on the base material plate 19, and the position of the base material 16 is adjusted so that its outer side in the horizontal direction is against the inner side of the movable baffle 3, and at the same time, one side end of the base material 16 in the longitudinal direction is against a group of front positioning parts 20, so that the overall position of the base material 16 can be determined and successfully positioned; finally, the base material pressing plate device 6 is adjusted, and the base material 16 is vertically pressed by the base material pressing plate 6-3 to complete the locking of the base material 16.

[0058] The clamp device 5 is arranged on the outer side of the first positioning rib 2-1, and comprises a clamp mounting plate 5-2 fixed on the sliding plate 1, and a plurality of clamps 5-1 are arranged on the clamp mounting plate 5-2 along the longitudinal direction of the sliding plate 1, and the working end of each group of clamps 5-1 faces the inner side of the first positioning rib 2-1;

[0059] On the inner side of the first positioning rib 2-1, the movable pressing plate 4 and the clamp device 5 cooperate to implement the positioning and pressing and fixing of the pole lug 17. Specifically, first open the working ends of all clamps 5-1; secondly, place the pole lug 17 on the pole lug placement plate 18, adjust the outer side of the pole lug 17 in the horizontal direction to abut against the inner side of the first pole lug baffle 2-11, and at this time, the inner side of the pole lug 17 in the horizontal direction abuts against the outer side of the above-mentioned parent material pressing plate 6-3, thereby completing the preliminary positioning of the pole lug 17; then, press the pole lug 17 vertically with the movable pressing plate 4, and the L-shaped bending part of the movable pressing plate 4 vertically presses the first pole lug baffle 2-11; finally, close the working ends of all clamps 5-1 to press and lock the movable pressing plate 4 in the gravity direction, thereby achieving the pressing of the pole lug 17. At this time, a certain gap is left between the inner edge of the movable pressure plate 4 and the outer edge of the above-mentioned base material pressure plate 6-3. When the subsequent rolling welding operation is performed, the welding head 9-1 of the welding machine device 9 moves along the gap to weld the vertically overlapping part of the pole ear 17 and the base material 16.

[0060] Furthermore, an array of magnet units 21 arranged in a matrix is ​​provided on the tab placement plate 18 . When the tab 17 is placed on the tab placement plate 18 , the tab 17 is magnetically adsorbed by the magnet unit 21 to provide preliminary adsorption and auxiliary positioning.

[0061] The driving device 7 comprises a driving motor 7-1 and a set of slide rails 7-6 fixedly mounted on the slide bracket 14, and a driving wheel group 7-2 and a driven wheel group 7-3 which are axially arranged and rotatable. The output end of the driving motor 7-1 is drivingly connected to the driving wheel group 7-2. A synchronous belt 7-3 is wound in a closed loop between the driving wheel group 7-2 and the driven wheel group 7-3. The synchronous belt 7-3 is sleeved and fixedly connected to a belt connector 7-4 mounted on the sliding plate 1. At the same time, a slider which is meshed and connected to the slide rail 7-6 is provided at the bottom of the sliding plate 1 (due to Figure 7 viewing angle and not shown).

[0062] Driven by the driving motor 7-1, the synchronous belt 7-3 drives the sliding plate 1 as a whole to reciprocate in the longitudinal direction through the belt connector 7-4, so as to send the vertically overlapping part of the pole ear 17 and the base material 16 after the above-mentioned positioning and compression locking to the rolling welding device 9 and the bottom mold device 8 for welding.

[0063] Furthermore, an array of photoelectric detection switch components can be provided on the skateboard bracket 14 to dynamically detect and feedback the distance and speed of the sliding plate 1 driven by the driving device 7, so as to know the real-time position of the vertical overlap of the pole ear 17 and the base material 16 relative to the roll welding device 9, so as to facilitate the overall control of the implementation of the roll welding process.

[0064] The bottom mold device 8 comprises a set of sliding guide rails 8-4 fixedly mounted on the bottom plate 10, the mounting plate 8-3 is meshedly connected to the sliding guide rails 8-4 through the bottom mold slider 8-8 at the bottom thereof, a lifting drive assembly 8-2 is mounted on the mounting plate 8-3, and the output end of the lifting drive assembly 8-2 is driven and connected to the bottom mold 8-1 through the pressure detection assembly 8-5;

[0066] During welding, the pressure detection component 8-5 detects in real time the pressure value exerted on the bottom mold 8-1 due to contact with the base material 16, and feeds back the pressure value to the PLC to dynamically adjust the driving force output by the lifting drive component 8-2, thereby stably providing the pressure required for welding and effectively protecting the bottom mold 8-1, the base material 16 and the tab 17 from damage due to excessive pressure.

[0067] According to the process requirements of the size and specifications of the plate production, during the process of selecting and adjusting the appropriate bottom mold 8-1, the fixed block 8-6 is used to limit the installation device from the far end, and the fixed clamp 8-7 is used to position and press and lock the installation plate 8-3. During welding, the position of the installation plate 8-3 is relatively fixed; when the bottom mold 8-1 needs to be replaced, the fixed clamp 8-7 is first opened to release the installation plate 8-3, and it is pulled out along the sliding guide rail 8-4. After the bottom mold 8-1 is replaced, it is pushed back to the fixed block 8-6 and re-locked by the fixed clamp 8-7.

[0070] Furthermore, welding head adjustment screws 9-7 and detection tables 9-8 are respectively installed on the lateral sides of the welding machine bracket 9-6, so that the positions of the two side ends can be manually adjusted when the welding machine 9-10 is connected to the bottom of the welding machine bracket 9-6, thereby controlling the welding machine bracket 9-6 to remain relatively parallel to the above-mentioned sliding plate 1. The position accuracy of the welding machine bracket 9-6 can be fine-tuned by the welding head adjustment screws 9-7 to within 0.02mm.

[0071] Further, multiple sets of bearings 9-61 and welding machine adjustment screws 9-62 are symmetrically arranged on both sides of the bottom of the welding machine bracket 9-6, and the welding machine 9-10 is pushed in along the bearings 9-61 and fixed to the bottom of the welding machine bracket 9-6, and the welding machine adjustment screws 9-62 are against the lateral sides of the welding machine 9-10.
