[0035] Reference Figures 1 to 4 , an embodiment of the present application provides a core-to-shell device.
[0036] The core-to-shell device comprises:
[0037] A bottom plate 1 and a first driving member 2, wherein the bottom plate 1 is used to place the pole core 001 and the aluminum shell 002, and the first driving member 2 is arranged on the bottom plate 1, and the first driving member 2 can drive the pole core 001 to move;
[0038] The first positioning member 3 is arranged on the bottom plate 1, and the first positioning member 3 includes a first side 31 and a second side 32 opposite to each other. The first positioning member 3 is provided with an opening, and the opening connects the first side 31 and the second side 32. The first side 31 is used to position the aluminum shell 002, and the second side 32 is used to penetrate the pole core 001 and enable the pole core 001 to pass through the opening into the aluminum shell 002.
[0039] Specifically, the bottom plate 1 may be provided with a core placement plate and an aluminum shell placement plate, respectively. The core placement plate is used to place the core 001, and the aluminum shell placement plate is used to place the aluminum shell 002, which can avoid the abnormal material collection caused by the disorder of placing the core 001 and the aluminum shell 002 on the bottom plate 1, thereby facilitating the assembly of the core 001 and the aluminum shell 002. Among them, grooves may be formed on the core placement plate and the aluminum shell placement plate, respectively, to accommodate and fix the core 001 and the aluminum shell 002.
[0040] like Figure 1 As shown, the first driving member 2 is disposed on the bottom plate 1, and the first driving member 2 may include a combination of a motor and a screw rod, or may include a combination of a motor and a slider. The first driving member 2 may be connected to the pole core placement plate, and drive the pole core 001 thereon to move by driving the pole core placement plate to move, so that the pole core 001 can approach the aluminum shell 002 until it enters the aluminum shell 002.
[0041] like Figures 1 to 3As shown, a first positioning member 3 is also provided on the bottom plate 1 , and the first positioning member 3 is usually located in the middle of the bottom plate 1 , so that the assembly part (ie, the shell insertion part) of the pole core 001 and the aluminum shell 002 can be positioned by using the two sides of the first positioning member 3 .
[0042] Specifically, the first positioning member 3 may include a first side 31 and a second side 32 opposite to each other, and the first side 31 and the second side 32 are two opposite side surfaces of the first positioning member 3. The first side 31 is close to the aluminum shell placement plate, and the second side 32 is close to the pole core placement plate. The first side 31 can position the aluminum shell 002, and the second side 32 can position the pole core 001, so as to improve the positioning accuracy of the assembly part (i.e., the shell entry part) of the pole core 001 and the aluminum shell 002, thereby improving the shell entry yield and stability of the pole core shell entry device.
[0043] In addition, the first positioning member 3 is provided with an opening, which connects the first side 31 and the second side 32. Under the drive of the first driving member 2, the pole core 001 can pass through the opening from the second side 32 and enter the aluminum shell 002. That is, the movement of the pole core 001 can be directed and guided by the opening on the first positioning member 3, thereby reducing the risk of failure of the pole core 001 to enter the shell due to the movement deviation of the pole core 001, and also improving the shell entry yield and stability of the pole core shell entry device.
[0044] Optionally, the first side 31 has a limiting flange 311 , and the limiting flange 311 can abut against the aluminum shell 002 .
[0045] like Figure 3 As shown, the limiting flange 311 extends inwardly along the side wall of the opening, so that when the aluminum shell 002 is penetrated, the limiting flange 311 can be against the outer wall of the aluminum shell 002 and position the aluminum shell 002, thereby avoiding the shaking or inaccurate positioning of the aluminum shell 002, and also improving the positioning accuracy of the assembly part of the pole core 001 and the aluminum shell 002 (that is, the shell insertion part).
[0046] The limiting flange 311 may be disposed on one side wall of the opening, or on two opposite side walls of the opening, or on four side walls of the opening to meet different positioning requirements.
[0047] Optionally, the limiting flange 311 and the side wall of the opening form a limiting space, and the limiting space is used to form circumferential positioning for the aluminum shell 002.
[0048] Specifically, the opening side wall and the limiting flange 311 on the first positioning member 3 together form a limiting space, which is also the penetration space of the aluminum shell 002. The clearance between the aluminum shell 002 and the limiting space can facilitate the penetration process of the aluminum shell 002, while avoiding the shaking or inaccurate positioning of the aluminum shell 002, and can also improve the positioning accuracy of the assembly part (i.e., the shell insertion part) of the pole core 001 and the aluminum shell 002.
[0049] Optionally, the second side 32 has a guiding slope 321 , and the guiding slope 321 is used to guide the movement of the pole core 001 .
[0050] like Figure 4 As shown, the guide slope 321 can be formed by chamfering the opening, and the guide slope 321 can be used to guide the movement of the pole core 001, thereby reducing the risk of shell insertion failure caused by the movement deviation of the pole core 001, and also improving the shell insertion yield and stability of the pole core shell insertion device.
[0051] Optionally, the angle between the guide slope 321 and the bottom plate 1 ranges from 25 degrees to 35 degrees. For example, the angle between the guide slope 321 and the bottom plate 1 can be 25 degrees, 30 degrees, 35 degrees or other suitable angles, so that the formed guide slope 321 can conveniently guide the movement of the pole core 001, and the formation process of the guide slope 321 is simple and convenient to process.
[0052] Optionally, the four side walls of the opening located on the second side 32 all have the guiding slope 321 to guide the movement of the pole core 001 from the circumferential direction, so that the movement of the pole core 001 into the shell is more convenient and easy.
[0053] Optionally, the second side 32 further has a transition arc surface 322 , and the transition arc surface 322 is adjacent to the guiding inclined surface 321 .
[0054] like Figure 4 As shown, the portion of the opening located on the second side 32 is sequentially processed with a transition arc surface 322 and a guide slope 321, so that the contact portion between the pole core 001 and the second side 32 is smooth and rounded, which can protect the movement of the pole core 001 into the shell, reduce the risk of damage to the pole core 001 caused by the contact between the edges of the pole core 001 and the second side 32, and also facilitate the processing and formation of the guide slope 321.
[0055] Among them, the four side walls of the opening located on the second side 32 can be arranged to have a transition arc surface 322 and a guide slope 321, so as to protect the movement of the pole core 001 into the shell from the circumferential direction, and further reduce the risk of damage to the pole core 001 caused by the contact between the pole core 001 and the edges of the second side 32.
[0056] Optionally, a second positioning member 4 is further included, and the second positioning member 4 is arranged on the base plate 1. The second positioning member 4 includes a second positioning block and a second driving member. The second positioning block can be driven by the second driving member to abut against the pole core 001 and realize the positioning of the pole core 001 in the width direction.
[0057] like Figure 1 As shown, the second positioning member 4 is located on one side of the pole core 001, and the second positioning member 4 is used to roughly position the pole core 001. The second positioning member 4 includes a second positioning block and a second driving member, the second driving member can be a driving cylinder, the second positioning block can be a slider, a baffle, etc., and the second positioning block is connected to the driving end of the second driving member. Under the drive of the second driving member, the second positioning block can be against the pole core 001 to achieve rough positioning of the pole core 001 in the width direction.
[0058] Optionally, there are two second positioning members 4, and the two second positioning members 4 are used to realize the positioning of the pole core 001 in the width direction from opposite sides.
[0059] like Figure 1 As shown, two second positioning members 4 are provided and located at both sides of the pole core 001 in the width direction. Driven by the second driving member, the two second positioning blocks can extend from opposite sides and abut against the two ends of the pole core 001, thereby achieving rough positioning of the pole core 001 in the width direction.
[0060] Optionally, a third positioning member 5 is further included, and the third positioning member 5 is arranged on the base plate 1. The third positioning member 5 includes a third positioning block and a third driving member. The third positioning block can be driven by the third driving member to abut against the aluminum shell 002 and realize the positioning of the aluminum shell 002 in the length direction.
[0061] like Figure 1 As shown, the third positioning member 5 is located at the end of the aluminum shell 002, and the third positioning member 5 is used to roughly position the aluminum shell 002. The third positioning member 5 includes a third positioning block and a third driving member, the third driving member can be a driving cylinder, the third positioning block can be a slider, a baffle, etc., and the third positioning block is connected to the driving end of the third driving member. Under the drive of the third driving member, the third positioning block can be against the aluminum shell 002 to achieve rough positioning of the aluminum shell 002 in the length direction.
[0062] Optionally, it further includes an adsorption member 6 , which is disposed on the bottom plate 1 and is used to adsorb two opposite sides of the aluminum shell 002 .
[0063] like Figure 1As shown, along the height direction of the bottom plate 1, that is, the up and down direction, the adsorption component 6 is arranged on the upper and lower sides of the aluminum shell 002. The adsorption component 6 can adsorb the upper and lower surfaces of the aluminum shell 002 to expand the opening of the aluminum shell 002 on the side facing the pole core 001 to facilitate the pole core 001 to enter the aluminum shell 002.
