[0036] from Figure 2It can be seen that the assembly carrier S has an assembly area, and the assembly area includes a positioning structure for the outer shell S1; before the inner shell S2 is installed, the outer shell S1 is pre-placed in the positioning structure D1.

[0037] Figure 3 It is a schematic diagram of the utility model after being used in coordination with the assembly carrier S on the rotating platform.

[0038] like Figure 3-21 As shown, it is not difficult to see that the two parts of the inner shell punching mechanism F1 and the inner shell feeding mechanism F2 in the utility model are both close to the edge of the rotating platform. This is because the feeding platform 1 of the inner shell feeding mechanism F2 is provided with a guide groove 2 adapted to the inner shell S2, and a pushing member 3 located in the guide groove 2. When the inner shell S2 is located in the guide groove 2, the pushing member 3 performs linear motion along the guide groove 2, and the inner shell S2 is pushed out of the feeding platform 1 through the guide groove 2. When assembling, the inner shell S2 in the guide groove 2 corresponds to the assembly area on the assembly carrier S.

[0039] Preferably, the punching area of ​​the inner shell punching mechanism F1 is adjacent to the feeding table 1, which can shorten the distance between the inner shell S2 transferred from the inner shell punching mechanism F1 to the feeding table 1, and a feeding mechanism F3 is provided between the inner shell punching mechanism F1 and the inner shell feeding mechanism F2 for implementing the transfer of the inner shell S2.

[0040] It can be seen that the above-mentioned components constitute an inner shell delivery device suitable for assembling the carrier S.

[0041] The feeding mechanism F3 clamps the inner shell S2 by the clamping end C to achieve the transfer of the inner shell S2. A notch structure 1a opposite to the clamping end C is provided in the area adjacent to the guide groove 2 on the feeding table 1. A step is formed between the notch structure 1a and the guide groove 2. During the transfer, the clamping end C directly enters the notch structure 1a. The purpose of setting the notch structure 1a is to guide the clamping end C to accurately place the inner shell S2 into the guide groove 2. The clamping end C is constrained by the two sides of the notch structure 1a to ensure that when the clamping end C releases the inner shell S2, the inner shell S2 is placed in the guide groove 2 at a preset position.

[0042] Since the positioning structure D1 on the assembly carrier S only positions the side of the outer shell S1, when the inner shell S2 enters the outer shell S1, a resultant external force will be generated on the outer shell S1. This resultant external force will cause the outer shell S1 to shift to the top of the positioning structure D1. This problem will affect the subsequent assembly process and lose the basic function of the positioning structure D1. By providing a baffle 4 covering the top of the guide groove 2 at the outlet near the guide groove 2, the baffle 4 extends to the outside of the feeding table 1. When the inner shell S2 is fed, the baffle 4 covers the outer shell S1. When the inner shell S2 is fed into the outer shell S1, the baffle 4 has a positioning effect, thereby constraining the outer shell S1 within the positioning structure D1.

[0043] It should be noted that a window structure is provided on the baffle 4, and the window structure allows the clamping end C to enter the notch structure 1a.

[0044] The inner shell feeding mechanism F2 also includes a first pushing cylinder 5 arranged on the feeding platform 1. The guide grooves 2 are distributed in a local area of ​​the surface of the feeding platform 1. The first pushing cylinder 5 is arranged on other areas of the surface of the feeding platform 1 and is connected to the pushing member 3.

[0045] The rotating platform will transfer the assembly carrier S to different processes. Therefore, there is a gap between the inner shell feeding mechanism F2 and the assembly carrier S, otherwise there will be a risk of mutual interference. Sufficient space needs to be reserved to prevent the above problems: the feeding table 1 is arranged on a table part 7 with a first sliding component 6, and a second pushing cylinder 8 is provided on the table part 7. The piston rod of the second pushing cylinder 8 is connected to the above-mentioned feeding table 1, and the feeding table 1 is controlled by the first sliding component 6 to approach or move away from the assembly carrier S.

[0046] The feeding mechanism F3 is a robot arm, which is arranged on a linear moving mechanism. The linear moving mechanism is a prior art, so its specific structure is not described in detail.

[0047] The punching action of the inner shell punching mechanism F1 is performed from bottom to top to avoid interference with the feeding mechanism F3.

[0048] The inner shell punching mechanism F1 includes a feeding plate 9, a punching head 10, and a driving assembly 11:

[0049] A feeding trough 9a is provided on the feeding plate 9, and an opening structure is provided at the end of the feeding trough 9a. The punching head 10 is located below the end of the feeding trough 9a and is maintained in a relative state with the opening structure. A stopper 12 is also provided on the feeding plate 9 and is located above the opening structure. When punching the inner shell S2, the stopper 12 serves to prevent the inner shell S2 from being pushed out further. The connecting edge between the inner shell S2 and the edge material L is cut off by the action of the stopper 12 and the punching head 10.

[0050] In the embodiment, the driving assembly 11 for driving the punching head 10 includes a driving motor 13, a belt, a driven roller 14, a turntable 15, a movable rod 16, and a mounting base 17. The driving motor 13 drives the driven roller 14 to rotate through the belt. A pair of turntables 15 are provided and are sleeved on the driven roller 14. There is a gap between the turntables 15. The sides opposite to each other between the turntables 15 are provided with a notch structure. A cam 18 is provided in the notch structure. A guide track 19 is formed between the cam 18 and the notch structure. The middle or near-middle area of ​​the movable rod 16 is rotatably connected to the mounting base 17. A bearing 20 is provided at one end thereof and is slidably connected to the guide track 19. The other end is connected to the punching head 10. The cam 18 has a Or multiple lowest points and highest points, when the bearing 20 is at the lowest point, it will be guided to press the bearing 20 downward. At this time, the punching head 10 is lifted up, pushing the punching head 10 to press the connecting edge onto the stopper 12. In addition, the inner circumference of the recessed structure corresponds to the outer circumference of the cam 18. Under the action of the driving motor 13, the turntable 15 rotates, and the movable rod 16 is rotated by pulling the guide track 19. Due to the small space under the feeding plate 9, the use of a universal cylinder to drive the punching head 10 will result in insufficient sliding stroke, resulting in the punching head 10 being unable to withdraw from the opening structure. The advantage of the drive assembly 11 of the utility model is that the structure is laterally distributed, simple and compact, and can accurately realize the required motion law.

[0051] The feeding plate 9 corresponding to the punching area is supported by a supporting member 21 below. A second sliding assembly is provided on the supporting member 21, and the punching head 10 is arranged on a slide block of the second sliding assembly.

[0052] A feeding assembly is also provided on the feeding plate 9, and the feeding assembly includes a feeding cylinder 22, a feeding slider (not shown in the figure), a feeding slide rail 24, a feeding rotary block 25, and a feeding connecting seat 26. The feeding slider and the feeding cylinder 22 are arranged on the area of ​​the feeding plate 9 close to the feeding slot 9a, and the feeding connecting seat 26 is connected to the feeding slider. The feeding connecting seat 26 has an area covering the upper part of the material belt and is provided with a mounting groove opposite to the edge material L. The feeding rotary block 25 is arranged in the mounting groove and is rotatably connected to the mounting groove to ensure that the tip 25' at the bottom of the feeding rotary block 25 can be against the edge material L on the material belt. The feeding cylinder 22 The piston rod is connected to the feeding connection seat 26. Under the action of the feeding cylinder 22, the feeding connection seat 26 moves along with the feeding slider, and the feeding rotary block 25 connected thereto also moves on the edge material L. A plurality of openings L' are reserved on the edge material L. When the tip 25' moves to the opening L', it is naturally screwed into the opening L' under the influence of its own weight, and the tip 25' is stuck in the opening L'. As the feeding cylinder 22 continues to push, the material belt is pushed by the tip 25'; that is, the tip 25' is screwed into the opening L', and under the constraint of the opening L', the feeding rotary block 25 pushes the material belt stably.

[0053] The above is the use process of a single material pushing. When in use, the feeding cylinder 22 continuously makes a reciprocating motion to bring the tip 25' to the opening L' behind the material belt; when the feeding cylinder 22 retreats, the tip 25' rotates in the opposite direction and rotates out from the opening L', and enters the opening L' behind the material belt without affecting the position of the material belt.

[0054] The above-mentioned feeding assembly also includes a guide seat 27, which is arranged on the area of ​​the feeding plate 9 close to the feeding groove 9a and extends above the material belt. The guide seat 27 is provided with a guide groove 27' corresponding to the edge material L, and the tip 25' passes through the guide groove 27' and enters into the opening L'; the purpose of using the guide seat 27 is to constrain the tip 25', and this constraint can ensure that the tip 25' can enter the opening L' of the material belt every time.
