Description

Technical Field

[0001] The invention relates to the technical field of thermal battery pole piece processing, in particular to a disposable thermal battery annular pole piece demoulding device. Background Art

[0002] Disposable thermal batteries, also known as heat-activated batteries, are widely used in military and defense, aviation and aerospace, industry and scientific research, medical equipment, deep-sea exploration, polar exploration and other fields because of their high energy density, long storage life and rapid activation and discharge.

[0003] A disposable thermal battery consists of electrodes, an activation device, an insulation layer, a stainless steel metal shell and external terminals. Since a thermal battery needs to be stacked with multiple electrodes, the amount of electrodes used in a disposable thermal battery is very large.

[0004] During the production of thermal battery pole pieces, the pole powder of the thermal battery needs to be formed into thin disc-shaped battery pole pieces in the mold by the servo press under high pressure, and then the battery pole pieces are removed from the mold by the servo press. The current production line uses a method of directly pushing the suspended demolding with a pressure head. The demolding principle is as follows: Figure 1 As shown, the die 26 is set on the pad 45, and the ram 27 is movably set in the die 26. The ram 27, the die 26 and the pad 45 are all located between the servo press upper template 43 and the servo press lower template 44. When the ram 27 moves vertically downward, the hot battery electrode 37 at the bottom of the ram 27 is discharged from the middle through hole of the die 26 and the pad 45.

[0005] The current demoulding device leaves the bottom of the thermal battery electrode in an unconstrained suspended state during the demoulding process. Since the thermal battery electrode is hard and brittle after high-pressure forming, the thermal battery electrode is subjected to uneven force when being removed from the mold, which can easily cause cracks or breakage, resulting in a high defective rate of the thermal battery electrode. A high defective rate means a waste of raw materials and an increase in the company's production and time costs. Therefore, how to improve the demoulding equipment has become a difficult problem that companies urgently need to solve. Summary of the Invention

[0053] A fixing assembly is provided on the mounting plate 1 and is used to fix the mold base 25;

[0054] In this example, see Figure 3-Figure 8 The support member is used to support the mounting plate 1 so that the mounting plate 1 has a certain distance from the plane on which the device is placed, thereby enabling the core shaft 28 in the demoulding assembly to be withdrawn from the elastic stripping assembly 24;

[0055] The electric push rod 4 is vertically downwardly arranged on the housing assembly.

A second shell 1-2 is also provided at the top of the first shell 1-1 and located on the outside of the pair of support plates 2. The second shell 1-2 closes the pair of support plates 2 and the electric push rod 4 arranged on its inner side.

[0063] As an embodiment of the present invention, the telescopic end of the electric push rod 4 is connected to the main pressure rod 5 through the connecting pin 6, and a first slot-shaped photoelectric switch 8 is provided on one of the support plates 2. The first slot-shaped photoelectric switch 8 can sense the position of the connecting pin 6 and send a position signal. The bottom of the main pressure rod 5 is threadedly connected to the adjustable ejector rod 12;

[0064] In this example, see Figure 3 and Figure 4 The main pressure rod 5 is hinged to the telescopic end of the electric push rod 4 through a connecting pin 6, and the connecting pin 6 is fixed by a cotter pin. The connecting pin 6 also serves as a stroke sensor of the electric push rod 4. A slot-type photoelectric switch mounting plate 7 is provided on one of the support plates 2 (the support plate 2 on the right side in the figure of the present invention). A long hole is opened on the slot-type photoelectric switch mounting plate 7.

A pair of through grooves are provided on both sides of the locator 22. The left support clamp 20 and the right support clamp 21 can be embedded in the pair of through grooves to fix the mold base 25.

[0075] In this example, see Figure 3 and Figure 4The motor 15 is preferably a stepper motor, but can also be other motors that can achieve precise control effects. The forward and reverse screws 17 are threadedly connected to the left support clamp 20 and the right support clamp 21. When the motor 15 is started, the motor 15 drives the forward and reverse screws 17 to rotate, and the forward and reverse screws 17 drive the threaded left support clamp 20 and the right support clamp 21 to move toward or away from each other. When the left support clamp 20 and the right support clamp 21 move toward each other, they can be embedded in a pair of through grooves opened on both sides of the locator 22 to clamp the mold base 25.

[0080] The above electrical components are connected through wires. The specific connection and control sequence should refer to the following working principle. The electrical connection between the electrical components is completed in the working order. The detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0081] The working principle and use process of the present invention:

[0082] Before demoulding the hot battery electrode 37, adjust the position of the positioner 22, such as Figure 15 As shown, specifically: turn on the power of the device, install the ejector rod calibrator 42 on the main pressure rod 5, and lock the ejector rod calibrator 42 by the clamping screw 11, push the locator 22 to the predetermined position (do not tighten it first), and then push the process mold base 48, process die 47 and process pressure head 46 used for calibration to the bottom of the main pressure rod 5 (the process mold base 48, process die 47 and process pressure head 46 are completely consistent with the mold base 25, die 26 and pressure head 27 in the demoulding component of this device in terms of appearance, size and installation form. The mold base 25, die 26 and pressure head 27 in the demoulding component of this device need to be heat treated, while the process mold base 48, process die 47 and process pressure head 46 do not need to be heat treated. The process mold base 48, process die 47 and process pressure head 46 The process pressure head 46 is only used for alignment and calibration). At this time, the process die base 48 is stuck in the locator 22, the process die 47 is above the locator 22, the process pressure head 46 is in the mounting hole of the process die 47 and above the process die base 48, and the electric push rod 4 is in the jog state to push the ejector rod calibrator 42 into the core shaft hole 27-1 opened on the process pressure head 46, so that the ejector rod calibrator 42 is aligned with the core shaft hole 27-1, and the locator 22 is fitted with the surface of the process die base 48 and then fixed to the mounting plate 1 by screws. The ejector rod calibrator 42, the process die base 48, the process die 47 and the process pressure head 46 are removed, and the adjustable ejector rod 12 is installed on the main pressure rod 5. The demoulding stroke of the adjustable ejector rod 12 is adjusted according to product requirements and then locked.

[0083] When the hot battery pole piece 37 is demoulded, Figure 3 and Figure 10-12 As shown, push the demoulding assembly (containing the pressed annular thermal battery electrode 37) into the positioning surface of the positioner 22, press the lighted button 13, the motor 15 starts, the motor 15 drives the forward and reverse screws 17 to rotate, the forward and reverse screws 17 drive the left support clamp 20 and the right support clamp 21 to move to clamp the mold base 25, the electric push rod 4 pushes the main pressure rod 5 and the adjustable ejector rod 12 to move downward, the adjustable ejector rod 12 withdraws the pressure head 27 and the core shaft 28 in the mold base 25 (please refer to the process of withdrawing the core shaft 28) Figure 10 and Figure 11 ), the electric push rod 4 will pause for 1.5 seconds. At this time, the motor 15 will reverse and drive the left support clamp 20 and the right support clamp 21 to move back and away from the mold base 25 to release the fixation of the mold base 25. After 1.5 seconds, the electric push rod 4 will continue to push down. Figure 12As shown, at this time, the horizontal raised portion of the adjustable ejector rod 12 will be pressed onto the pressure head 27, and the adjustable ejector rod 12 will drive the pressure head 27 to move vertically downward. Since the positioner 22 is fixed to the mounting plate 1 by screws, and the die 26 is arranged above the positioner 22, the pressure head 27 will move the die base 25 when it moves vertically downward, and the die base 25 will move the push shaft 30 downward, and the push shaft 30 will compress the spring 32. The positioner 22 supports the die 26 and cannot move vertically downward, thereby causing the hot battery electrode 37 located below the pressure head 27 to be pushed out of the die 26. During the entire demoulding process, under the elastic force of the spring 32, The top of the push shaft 30 is always in contact with the bottom of the mold base 25, so that the mold base 25 continues to support the thermal battery electrode 37, that is, the pressure head 27 and the mold base 25 are always in a compressed state on the thermal battery electrode 37, thereby preventing the bottom of the thermal battery electrode 37 from being in a suspended state during the demoulding process and causing cracks or breakage, thereby improving the product qualification rate. After the thermal battery electrode 37 is pushed out of the die 26, the telescopic end of the electric push rod 4 contracts and drives the adjustable ejector rod 12 to move vertically upward and withdraw from the core shaft hole 27-1. The personnel manually remove the pressure head 27 and the die 26, and then take out the thermal battery electrode 37, thus completing the entire demoulding process.
