DETAILED DESCRIPTION

[0024] In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the utility model are described in detail with reference to the accompanying drawings for the preferred embodiments of the utility model and their features and functions.

[0025] As attached Figure 1-3 As shown, the utility model provides a three-axis positioning mechanism of an energy storage type sealing and welding machine, including an X-axis motion mechanism, a Y-axis motion mechanism, a Z-axis motion mechanism, a clamping mechanism and a grating ruler.

[0026] The Y-axis motion mechanism includes a base plate 1, a rolling guide 2, a slide 3 and a linear motor 4. Two rolling guides 2 are provided, which are symmetrically arranged on the base plate 1. The slide 3 is arranged on the slider of the rolling guide 2, and the linear motor 4 is arranged between the two rolling guides 2. The stator of the linear motor 4 is parallel to the rolling guide 2 and fixedly connected to the base plate 1. The mover of the linear motor 4 is fixedly connected to the slide 3, so that the slide 3 is driven to slide on the rolling guide 2 by the linear motor 4. The scale grating of the grating ruler 19 is arranged on the side wall of the base plate 1 and parallel to the rolling guide 2. The grating degree head of the grating ruler 19 is arranged on the slide 3 and adapted to the scale grating, so as to detect the moving distance of the slide 3.

[0027] The X-axis motion mechanism is arranged on the slide 3 of the Y-axis motion mechanism. The structure of the X-axis motion mechanism is the same as that of the Y-axis motion mechanism. The motion direction of the mover of the linear motor 4 of the X-axis motion mechanism is perpendicular to the motion direction of the mover of the linear motor 4 of the Y-axis motion mechanism.

[0028] The Z-axis motion mechanism comprises a guide column 5, a locking block 6, a workbench 7, a lifting screw 8 and a lifting nut 9. Four guide columns 5 are provided, evenly distributed on the four corners of the slide table 3 of the X-axis motion mechanism.

[0029] The lifting nut 9 is arranged at the center of the slide 3 of the X-axis motion mechanism, and the lifting screw 8 is arranged on the lifting nut 9 and is screwed with the lifting nut 9. The workbench 7 is provided with an opening adapted to the guide column 5 and the lifting screw 8, and the workbench 7 is sleeved on the guide column 5 and the lifting screw 8 through the opening, and the workbench 7 is slidably connected with the guide column 5, and the workbench 7 is fixedly rotatably connected with the lifting screw 8, so that the workbench 7 can slide on the guide column 5, and can rotate relative to the lifting screw 8 while the relative position with the lifting screw 8 does not change. The bottom of the workbench 7 is provided with a locking block 6, and the center of the locking block 6 is a circular hole adapted to the diameter of the guide column 5, and the locking block 6 is sleeved on the guide column 5 through the circular hole. One end of the locking block 6 is a slot that divides the locking block 6 into two parts on the left and right, and the circular hole can be connected to the outside through the slot, and both ends of the slot are provided with screw holes, and the two ends of the slot are connected by bolts inserted into the screw holes, and the ends of the bolts are threadedly connected with nuts. The operator can rotate the lifting screw 8 to adjust the distance that the lifting screw 8 is screwed into the lifting nut 9, thereby adjusting the height of the lifting screw 8, and then adjusting the height of the workbench 7 fixedly rotatably connected to the lifting screw 8. After determining the height of the workbench 7, the two ends of the slot on the locking block 6 are clamped by tightening the nut on the bolt, and then the locking block 6 is locked on the guide column 5, so that the workbench 7 and the locking block 6 cannot slide on the guide column 5.

[0030] The clamping mechanism includes a claw rolling guide rail 10, a claw cylinder 11, a claw bracket 12 and a claw 13. The claw rolling guide rail 10 and the claw cylinder 11 are arranged on the workbench 7. Two claw cylinders 11 are provided, which are relatively arranged on the same side of the claw rolling guide rail 10. A positioning block 14 fixedly connected to the workbench 7 is provided in the center of the two claw cylinders 11. The piston rods of the two claw cylinders 11 are collinear and close to the positioning block 14. The positioning block 14 is provided with an opening adapted to the piston rod. Two claw brackets 12 are also provided, corresponding to the claw cylinders 11 one by one. The middle part of the claw bracket 12 is fixedly connected to the slider of the claw rolling guide rail 10, one end is connected to the piston rod of the adjacent claw cylinder 11, and the other end is connected to the claw 13.

[0031] In actual use, before work, the operator needs to adjust the height of the claw 13 according to the height of the material carrier of the batch, so that the claw 13 can freely clamp the material on the material carrier. When adjusting, first manually rotate the lifting screw 8 to change the length of the lifting screw 8 screwed into the lifting nut 9. At this time, the height of the workbench 7 fixedly connected to the lifting screw 8 changes with the change of the length of the lifting screw 8 screwed into the lifting nut 9. At this time, the workbench 7 and the locking block 6 slide on the guide column 5. When the claw 13 on the workbench 7 reaches the height suitable for the material carrier of the batch, stop rotating the lifting screw 8 and tighten the nut on the locking block 6, so that the locking block 6 locks the guide column 5, and then the position of the workbench 7 is fixed, and the position of the claw 13 is fixed accordingly, ready to start work.

[0032] During operation, the claw cylinder 11 is first started, the piston rod of the claw cylinder 11 is contracted, and the two claws 13 are spaced a certain distance apart. Then the linear motor 4 is started to move the claws 13 on the X-axis and the Y-axis to make the claws 13 reach the picking position. Then the piston rod of the claw cylinder 11 is extended to clamp the material on the material carrier. Then the linear motor 4 is started again to continue to adjust the position of the claws 13 on the X-axis and the Y-axis to move the material to the process position. According to the actual process requirements, the claws 13 are opened or continue to clamp the material. After the main process equipment completes welding or mounting, the claws 13 are returned to the material carrier to clamp the next material and perform the next work cycle.

[0033] The two claw cylinders 11 of the present invention can be controlled separately. When clamping materials, the piston rod of one claw cylinder 11 can be extended first so that the claw bracket 12 on it is attached to the positioning block 14 to ensure accurate positioning. Then, the piston rod of the other claw cylinder 11 is extended so that the two claws 13 clamp the materials, thereby reducing the impact on the materials when clamping them and reducing the material loss.

[0034] In another embodiment, the claw cylinder 11 that is extended first has a larger cylinder diameter, and the claw cylinder 11 that is extended later has a smaller cylinder diameter, so as to further reduce the impact on the material when clamping the material.

[0035] In another embodiment, the Z-axis motion mechanism further includes a buckle 17, a countersunk hole is provided on the workbench 7, the size of the countersunk head of the countersunk hole is adapted to the buckle 17, the lifting screw 8 is sleeved on the workbench 7 through the countersunk hole, a rotating head 18 is provided on the top of the lifting screw 8, the buckle 17 is clamped on the rotating head 18, the buckle 17 is arranged in the countersunk head of the countersunk hole and is fixedly connected to the workbench 7. In this way, the lifting screw 8 can rotate relative to the workbench 7 while the positional relationship between the two does not change, so that when the lifting screw 8 rotates on the lifting nut 9, the workbench 7 can be kept from rotating while the height of the workbench 7 can be changed.

[0036] In another embodiment, proximity sensors 15 are provided at both ends of the bottom plate 1, and a sensing sheet 16 adapted to the proximity sensors 15 is provided at one end of the slide 3. In this way, the moving range of the device on the X-axis and the Y-axis is determined. When the bottom plate 1 is about to slide out of the rolling guide rail 2, the proximity sensor 15 will sound an alarm, and the staff can immediately stop the linear motor 4 to reduce the occurrence of accidents.

[0037] The above description is only the preferred embodiment of the utility model, not all embodiments. Anyone should be aware that structural changes made under the inspiration of the utility model, and all technical solutions that are the same or similar to the utility model, belong to the protection scope of the utility model.
