Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a button battery, a skirt shaping component and an electronic device. Background Art

[0002] Button cells, also known as button cells, refer to batteries that are shaped like a small button. Compared to cylindrical batteries, button cells have a larger diameter and a thinner thickness. The cells of traditional button cells are generally wrapped with aluminum-plastic film. Since the sides of the cells are arc-shaped, the aluminum-plastic film will form side sealing skirts on the sides of the cells, making it difficult to control the diameter of the button cells, resulting in large molding tolerances and packaging difficulties. In related technologies, in order to solve the above problems, a circle of outer tape is usually pasted on the side surfaces of the cells with trademark stickers attached to compress the raised side sealing skirts of the cells to achieve shaping and protection of the side sealing skirts. However, due to the small size of the cells, automated equipment cannot be used for automated attachment and pasting. Therefore, the above packaging process still requires manual work, which makes the packaging efficiency of button cells low and the consistency of product size poor. Utility Model Content

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0034] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can recognize the applicability of other processes and / or the use of other materials.

[0035] For ease of description, spatially relative terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or change in motion state, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will subsequently be oriented as "above" or "over" other elements or features. Thus, the exemplary term "below" can include both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatially relative descriptors used in the text are interpreted accordingly.

[0036] In the traditional technology, after the button cell is wrapped by an aluminum plastic film, a wavy corrugated skirt will be formed on the side of the cell. This corrugated skirt will warp or fly up, increasing the difficulty of controlling the outer diameter size of the entire button battery, resulting in a large tolerance for the semi-finished battery and affecting subsequent packaging. To solve the above problems, the traditional battery packaging process generally attaches a trademark axially to the semi-finished battery to strengthen the fixed shaping of the semi-finished product axially; then, a peripheral tape is wrapped around the semi-finished battery circumferentially to press the corrugated skirt to prevent it from warping or flying up, realizing the circumferential shaping and fixing of the semi-finished product. However, the trademark design involved in the above packaging process is complex, and the trademark and the peripheral tape are small in size (the diameter of the cell is generally 5 mm to 15 mm, so the sizes of the trademark and the peripheral tape arranged on the outside are also small), and they cannot be attached automatically by equipment and need to be attached manually, which makes the packaging efficiency of the button battery low; moreover, the obtained formed products are generally limited by the experience and proficiency of the operators, and the consistency is poor. Based on this, the present application provides a button battery, which can not only reduce the packaging process of the traditional button battery and improve the packaging efficiency, but also reduce the experience error and improve the consistency and yield rate of the finished button battery.

[0037] An embodiment of the present application provides a button battery, as Figures 1 to 6 shown, which includes: a cell 100, including a core body 110, a side sealing skirt 120 and an ear 130, the side sealing skirt 120 is wrapped around the circumferential side of the core body 110, and one end of the ear 130 extends out of the side sealing skirt 120; a first insulating protection member 200 is disposed on the top of the core body 110, and the part of the ear 130 extending out is located on the side of the first insulating protection member 200 facing away from the top of the core body 110; and a first encapsulation adhesive 400 is disposed on the outer periphery of the first insulating protection member 200 and at least covers the gap between the top of the core body 110 and the side sealing skirt 120.

[0038] In this embodiment, the first insulating protection member 200 is disposed between the top surface of the tab 130 and the core 110 to prevent the tab 130 from scratching or piercing the top surface of the core 110, resulting in leakage of the electrode material in the core 110, improving the mechanical protection of the core 110, and enhancing the safety of use of the button cell. At the same time, the first encapsulating adhesive 400 is disposed at the outer peripheral edge of the first insulating protection member 200 and at least covers the gap between the core 110 and the side sealing skirt 120, so as to improve the connection tightness between the first insulating protection member 200, the core 110 and the side sealing skirt 120 at least at the top surface of the battery cell 100, and enhance the sealing performance between the core 110 and the side sealing skirt 120. In this way, on the one hand, the shape of the top of the side sealing skirt 120 can be fixed at least by the first encapsulating adhesive 400, preventing the side sealing skirt 120 at this position from warping or flying up, resulting in inconsistent radial dimensions of the button cell, and improving the forming consistency and yield rate of the button cell. On the other hand, it can prevent the electrode material from leaking from the gap between the side sealing skirt 120 and the core 110, and improve the safety of use of the button cell. In addition, compared with the traditional encapsulation process of encapsulating the battery cell 100 with multiple layers of tapes, the encapsulation operation of the button cell provided in this application simplifies at least the encapsulation processes such as attaching trademarks and pasting peripheral tapes on the outside of the battery cell 100, and only needs to arrange the first encapsulating adhesive 400 on the top of the battery cell 100. The encapsulation process of the entire button cell has fewer steps, high encapsulation efficiency, and good consistency of the encapsulated products.

[0039] Specifically, the button cell is configured as a combined component at least including a battery cell 100, a first insulation protection member 200, and a first encapsulation adhesive 400. The battery cell 100 can be approximated as a flat cylindrical structure with a relatively large diameter and a relatively thin thickness. It is configured as a combined component at least including a core body 110, a side-sealing skirt 120, and a tab 130. The core body 110 is internally encapsulated with electrode materials for providing power. The side-sealing skirt 120 can be made of aluminum-plastic film and is wrapped around the arc-shaped cylindrical side of the core body 110, forming certain wrinkles in the circumferential direction of the battery cell 100. The tab 130 can be a rectangular metal block, one end of which is connected to the top of the side-sealing skirt 120 and can be folded over the side-sealing skirt 120. In this way, during the encapsulation process, the operator can fold the tab 130 outward to reserve an installation space for the first insulation protection member 200 on the top surface of the core body 110. Then, after the first insulation protection member 200 is assembled, the tab 130 is folded inward so that the free end of the tab 130 abuts against the top surface of the first insulation protection member 200. In this way, it can not only prevent the free end of the tab 130 from piercing the top of the core body 110 through the first insulation protection member 200, improving the yield rate of the button cell, but also further improve the connection tightness between the first insulation protection member 200 and the core body 110 through the abutment of the tab 130, improving the structural reliability of the button cell. Two tabs 130 can be configured, and the two tabs 130 respectively lead out the positive and negative poles of the core body 110. The first insulation protection member 200 can be NOMEX adhesive paper, which can be circular and slightly smaller in size than the top surface of the core body 110 to reserve a space for dispensing glue at the peripheral edge of the top surface of the core body 110. The first insulation protection member 200 can be connected to the core body 110 by pasting. The first encapsulation adhesive 400 can be a flowing colloid, which at least has a flowing state and a fixed state. The operator or automated equipment can first place the semi-finished battery cell 100 into a designated encapsulation and shaping mold, and then dispense the flowing first encapsulation adhesive 400 to the designated position, let it stand, and wait for it to solidify to form the required first encapsulation adhesive 400. At this time, the solid first encapsulation adhesive 400 is distributed on the outer periphery of the first insulation protection member 200 in the radial direction of the battery cell 100 to prevent dust and debris from entering between the first insulation protection member 200 and the core body 110 from the outer periphery of the first insulation protection member 200, realizing dust isolation protection for the outer periphery of the first insulation protection member 200 and improving the connection tightness between the first insulation protection member 200 and the core body 110. At the same time, the first encapsulation adhesive 400 covers at least the gap between the core body 110 and the side-sealing skirt 120 in the circumferential direction of the battery cell 100. In this way, it can not only prevent the electrode materials in the core body 110 from leaking out, improving the use safety of the button cell, but also prevent external dust and debris from entering the battery cell 100 and affecting the performance of the battery cell 100. This kind of encapsulation process is simple to operate. Only simple dispensing operations are required to simultaneously complete the processing and assembly of the first encapsulation adhesive 400, reducing the encapsulation difficulty and saving the processing time of the first encapsulation adhesive 400.

[0040] Of course, in other embodiments, the first packaging glue 400 can also be a solid colloid layer. In this case, in order to ensure the sealing performance between it and the first insulating protection member 200, the top outer periphery of the core 110, the gap between the core 110 and the side sealing skirt 120, and the top of the side sealing skirt 120, etc., the position contacting the first packaging glue 400 can be slightly heated to melt part of the first packaging glue 400 and have greater viscosity, thereby improving the connection tightness between the above components. In this packaging process, the first packaging glue 400 can be processed in batches in advance, and the first packaging glue 400 can be directly used during assembly, which can save the packaging time of waiting for the first packaging glue 400 to solidify and improve the packaging efficiency.

[0041] It should be explained that the inner side mentioned in the present application refers to the side of the component close to or facing the axis of the button battery, and the outer side refers to the side of the component far away from or away from the axis of the button battery.

[0042] In one possible embodiment, the first packaging glue 400 includes an annular body 410, the inner side of the annular body 410 abuts against the outer side of the first insulating protection member 200, the outer side of the annular body 410 is accommodated in the outer side of the battery cell 100, or the outer side of the annular body 410 is flush with the outer side of the battery cell 100.

[0043] In this embodiment, the specific configuration of the first packaging glue 400 is optimized. Specifically, the first packaging glue 400 body is configured into a ring-shaped structure, and its axially unfolded figure is a rectangle, the upper and lower surfaces are both flat, and the inner and outer side surfaces are arc-shaped surfaces. The top surface of the first packaging glue 400 is flush with the top surface of the first insulating protection member 200 or lower than the top surface of the first insulating protection member 200, so as to reduce the use of the first packaging glue 400, save packaging materials and packaging time, and improve packaging efficiency. The bottom surface of the first packaging glue 400 is flush with the top surface of the core 110 and the top surface of the side sealing skirt 120, or the first packaging glue 400 can be allowed to extend slightly downward from the top surfaces of the two in the gap between the two, so as to increase the contact area between the first packaging glue 400 and the surface of the battery cell 100, and improve the connection tightness and sealing waterproofness between the first packaging glue 400 and the core 110 and the side sealing skirt 120. The inner side wall of the first packaging glue 400 is attached and bonded to the outer side wall of the first insulating protection member 200, which can improve the connection tightness between the first packaging glue 400 and the first insulating protection member 200 and improve the structural stability of the button battery. The outer side wall of the first packaging glue 400 is flush with the outer side wall of the battery cell 100 or is accommodated in the outer side wall of the battery cell 100 to improve the appearance of the button battery.

[0044] In a possible implementation, in the radial direction of the battery cell 100, the width of the annular body 410 is 0.5 mm to 2 mm. With such a setting, it can avoid the first encapsulating adhesive 400 being too narrow to completely cover the gap between the core body 110 and the side sealing skirt 120, or being unable to achieve firm connection between the core body 110 and the side sealing skirt 120 after being too narrow, improve the shaping and fixing of the side sealing skirt 120, and avoid the side sealing skirt 120 from warping or flying up. Also, it can avoid the first encapsulating adhesive 400 occupying too much assembly space of the first insulating protection member 200, make the width of the first encapsulating adhesive 400 within a suitable range, improve the rationality of the internal layout of the button battery, and make the structure more compact.

[0045] In a possible implementation, in the axial direction of the battery cell 100, the thickness of the annular body 410 is 0.5 mm to 1.5 mm. With such a setting, it can avoid the first encapsulating adhesive 400 being too thin to cause glue detachment, improve the sealing performance between the core body 110 and the side sealing skirt 120, and improve the service safety and service life of the button battery. Also, it can avoid the first encapsulating adhesive 400 being too thick to make the overall thickness of the button battery unable to meet the usage scenarios with requirements for installation thickness, make the thickness of the first encapsulating adhesive 400 within a suitable range, and increase the applicable range of the button battery while ensuring the miniaturization of the button battery. For example but not limited to, the thickness of the annular body 410 can be set to 1 mm.

[0046] In a possible implementation, the first encapsulating adhesive 400 further includes an insertion part 420, and the insertion part 420 is arranged below the annular body 410 and extends into the gap between the core body 110 and the side sealing skirt 120.

[0047] In this embodiment, the specific configuration of the first encapsulating adhesive 400 is optimized. Specifically, the first encapsulating adhesive 400 is configured as a composite structure including at least an annular body 410 and an insertion part 420. The insertion part 420 is used to insert and connect to seal the gap between the core body 110 and the side sealing skirt 120, improve the shaping and fixing of the side sealing skirt 120, and it can be an irregular sheet structure, such as a long strip-shaped water droplet shape, a special-shaped shape with different thicknesses, a wedge shape, etc. The shape of the insertion part 420 is adapted to the shape of the gap between the core body 110 and the side sealing skirt 120, and is not limited.

[0048] In a possible implementation, as Figure 2As shown in the figure, in the radial direction of the battery cell 100, the insertion part 420 is located at the position of 1 / 2 to 2 / 3 of the annular body 410. With such a setting, by arranging the insertion part 420 at the middle position or an outer position of the annular body 410, half or most of the radial area of the annular body 410 can be connected to the core body 110, and the other half or a small part of the radial area can overlap on the gap and the side seal skirt 120. In this way, not only can the position stability of the first encapsulation adhesive 400 be improved, but also the top of the side seal skirt 120 can be firmly connected to the core body 110 through the stable first encapsulation adhesive 400, enhancing the shaping and fixing of the side seal skirt 120, effectively avoiding the top of the side seal skirt 120 from warping or flying up, and ensuring the consistency of the radial dimensions of the finished button battery.

[0049] In a possible implementation manner, as Figure 3 shown, the insertion part 420 is continuously distributed along the circumferential direction of the battery cell 100 between the gap of the core body 110 and the side seal skirt 120. With such a setting, by unfolding the insertion part 420 into a one-piece structure along its axial direction, the insertion part 420 can completely fill the gap between the core body 110 and the side seal skirt 120, improving the connection tightness and sealing performance between the core body 110 and the side seal skirt 120, and having a better shaping and fixing effect on the side seal skirt 120.

[0050] In a possible implementation manner, as Figure 4 shown, the insertion part 420 is spaced along the circumferential direction of the battery cell 100 between the gap of the core body 110 and the side seal skirt 120. With such a setting, by unfolding the insertion part 420 into an intermittent multi-point structure along its axial direction, the insertion part 420 can partially fill the gap between the core body 110 and the side seal skirt 120, saving the raw materials of the first encapsulation adhesive 400, saving the encapsulation time, and improving the encapsulation efficiency.

[0051] In a possible implementation manner, it further includes a lead-out member 300. One end of the lead-out member 300 is electrically connected to the tab 130, and the other end extends in a direction away from the battery cell 100.

[0052] In this embodiment, the specific configuration of the button battery is further optimized. Specifically, the button battery is configured as a combined component at least including the battery cell 100, the first insulation protection member 200, the first encapsulation adhesive 400, and the lead-out member 300. The lead-out member 300 can be a lead-out wire, one end of which can be electrically connected to the tab 130 by spot welding, and the other end extends outward to be electrically connected to external electrical components; two lead-out members 300 can be provided, and the two lead-out members 300 respectively lead out the positive and negative poles of the battery cell 100. In this example, the electrical connection end of the button battery is led out of the battery cell 100 through the lead-out member 300, which is beneficial to improving the compactness of the internal components of the button battery and facilitating the encapsulation of the button battery.

[0053] In a possible implementation, a second encapsulating adhesive 500 is further included, and the second encapsulating adhesive 500 is disposed outside the tab 130 and the lead-out member 300.

[0054] In this embodiment, the specific configuration of the button cell is further optimized. Specifically, the button cell is configured as a combined component including at least the battery cell 100, the first insulating protection member 200, the lead-out member 300, the first encapsulating adhesive 400, and the second encapsulating adhesive 500. The second encapsulating adhesive 500 can be a flowing colloid, which has at least a flowing state and a fixed state. An operator or an automated device can first place the semi-finished battery cell 100 into a specified encapsulating and shaping mold, and then dispense the flowing second encapsulating adhesive 500 onto the specified positions of the tab 130, the lead-out member 300, and their connection parts, and let it stand still until it solidifies to form the required second encapsulating adhesive 500. At this time, the solid second encapsulating adhesive 500 wraps outside the tab 130 and the lead-out member 300 connected to the tab 130 to achieve insulation protection for the tab 130 and at least part of the lead-out member 300. The outside of the second encapsulating adhesive 500 can be connected to the first encapsulating adhesive 400 to further improve the insulation protection of the lead-out member 300 corresponding to the first encapsulating adhesive 400. This kind of encapsulation process is simple in operation. Only simple dispensing operation is required to complete the processing and assembly of the second encapsulating adhesive 500 at the same time, reducing the encapsulation difficulty and saving the processing time of the second encapsulating adhesive 500.

[0055] Of course, in other embodiments, the second encapsulating adhesive 500 can also be a solid colloid layer. At this time, to ensure the sealing performance between it and the tab 130, the lead-out member 300, and the connection part between the tab 130 and the lead-out member 300, the position in contact with the second encapsulating adhesive 500 can be slightly heated to make part of the second encapsulating adhesive 500 melt and have greater adhesiveness, improving the connection tightness between the above components. This kind of encapsulation process can pre-process the second encapsulating adhesive 500 in batches, and the second encapsulating adhesive 500 can be directly used during assembly, which can save the encapsulation time for waiting for the second encapsulating adhesive 500 to solidify and improve the encapsulation efficiency.

[0056] In a possible implementation, a second insulating protection member 600 is further included, and the second insulating protection member 600 is disposed at the bottom of the battery cell 100.

[0057] In this embodiment, the specific configuration of the button cell is further optimized. Specifically, the button cell is configured as a combined component including at least the battery cell 100, the first insulating protection member 200, the lead-out member 300, the first encapsulating adhesive 400, and the second insulating protection member 600. The second insulating protection member 600 can be a double-sided adhesive, which is disposed at the bottom of the battery cell 100 for insulating protection of the bottom of the battery cell 100, and at the same time, the button cell can be adhered to a specified position of the electronic device through the second insulating protection member 600, facilitating the installation of the button cell.

[0058] In one example, the second insulating protection member 600 is configured to include at least a combined member of a double-sided adhesive layer and a protective adhesive paper. The double-sided adhesive layer is disposed on the protective adhesive paper, and the area of the double-sided adhesive layer is smaller than that of the protective adhesive paper. The protective adhesive paper is disposed on the side of the double-sided adhesive layer away from the battery cell 100 to protect the double-sided adhesive layer and prevent its viscosity from decreasing after being removed when adhered to a non-designated position, facilitating the transportation and handling of the button battery.

[0059] In a possible implementation manner, at least a part of the second insulating protection member 600 protrudes from the battery cell 100 in the radial direction of the battery cell 100. With such a setting, the second insulating protection member 600 can be assembled to the bottom surface of the battery cell 100 through the protruding part, and when assembling the button battery, the button battery can be assembled to the designated position of the electronic device by tearing off the protruding part. The disassembly and assembly are convenient and the efficiency is high.

[0060] In addition, the present application also provides a skirt shaping assembly applied to the button battery as described above. The skirt shaping assembly includes a fixing member 10 and a shaping seat 20. The fixing member 10 is provided with a receiving cavity, and the shaping seat 20 is movably disposed in the receiving cavity. The shaping seat 20 has a first opening 21 and a second opening 22 disposed opposite to each other, and the second opening 22 faces the bottom of the receiving cavity; the battery cell 100 of the button battery is inserted into the shaping seat 20 through the first opening 21, the outer peripheral side of the side sealing skirt 120 of the battery cell 100 abuts against the inner peripheral side of the shaping seat 20, the first insulating protection member 200 of the button battery protrudes from the first opening 21, and the first encapsulation adhesive 400 of the button battery is disposed between the shaping seat 20 and the first insulating protection member 200 and is located on the top of the battery cell 100.

[0061] In this embodiment, in order to achieve the encapsulation plasticity of the first encapsulation adhesive 400, a skirt shaping assembly applied to the button battery in this embodiment is specifically proposed. The skirt shaping assembly can be used to accommodate the battery cell 100 and shape the side sealing skirt 120 of the battery cell 100. After the battery cell 100 is fixed in the skirt shaping assembly, the first encapsulation adhesive 400 is dispensed from the side of the first opening 21 of the shaping seat 20 to the top of the side sealing skirt 120, the top of the core body 110, and above the gap between the side sealing skirt 120 and the core body 110. After it solidifies, the first encapsulation adhesive 400 can be assembled to the battery cell 100; then, the second encapsulation adhesive 500 can be dispensed from the side of the first opening 21 of the shaping seat 20 to the outside of the ear 130, the lead-out member 300, and the connection between the ear 130 and the lead-out member 300 to insulatively wrap the ear 130 and the lead-out member 300; then, the encapsulated button battery cell 100 is ejected from the side of the second opening 22 of the shaping seat 20, and the second insulating protection member 600 can be pasted on the bottom of the button battery cell 100 to complete the encapsulation of the button battery cell 100.

[0062] Specifically, the skirt shaping component is configured to include at least a combined component of a fixing member 10 and a shaping base 20. The fixing member 10 can be a cylindrical frame with an open end. The internal dimensions of the cylindrical frame are adapted to the external dimensions of the shaping base 20. The shaping base 20 can be inserted into the fixing member 10 from the open end of the fixing member 10. The shaping base 20 can be a cylindrical tube structure with open ends at both ends. The second opening 22 end of the cylindrical tube structure protrudes inward, so that the radial dimension of the second opening 22 is smaller than the radial dimension of the first opening 21, which can prevent the battery cell 100 assembled into the shaping base 20 from falling out from the second opening 22 side. The internal cavity dimensions of the shaping base 20 are adapted to the external dimensions of the battery cell 100. When the battery cell 100 is assembled into the shaping base 20, the outermost side-sealing skirt 120 of the battery cell 100 abuts against the inner wall of the shaping base 20 and is shaped and fixed by it. The first insulation protection member 200 at the top of the battery cell 100 extends out of the first opening 21, and the lead-out member 300 and the pole ear 130 buckled on the first insulation protection member 200 both extend out of the first opening 21. At this time, the peripheral edge of the top of the shaping base 20 is slightly higher than the top surfaces of the core body 110 and the side-sealing skirt 120. The first encapsulation glue 400 can be dispensed at the peripheral edge of the shaping base 20. A dispensing cavity for the first encapsulation glue 400 is formed by enclosing the inner wall of the top of the shaping base 20, the top of the side-sealing skirt 120, the peripheral edge of the top of the core body 110, and the outer wall of the first insulation protection member 200, and the first encapsulation glue 400 is plastically encapsulated.

[0063] Moreover, for the specific structure of the button battery, refer to the above-mentioned embodiments. Since the skirt shaping component applied to the button battery as described above adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.

[0064] In a possible implementation manner, the fixing member 10 includes a fixing base 11 and a push rod 12. The accommodating cavity is arranged in the fixing base 11. The push rod 12 is movably connected below the fixing base 11 and is used to eject the shaping base 20 located in the accommodating cavity.

[0065] In this embodiment, the specific configuration of the fixing member 10 is optimized. Specifically, the fixing member 10 is configured as a combined member including at least a fixing base 11 and a push rod 12. The fixing base 11 can be a cylindrical frame with an open end, and an activity hole is provided at its bottom. The push rod 12 can be a rod-shaped structure, which includes a rod portion and a limiting plate connected in a T shape. The limiting plate can be a circular plate, which is movably received in the fixing base 11 and has a size larger than that of the activity hole to prevent the push rod 12 from detaching from the fixing base 11. The rod portion can be a thin cylindrical rod, one end of which can be connected below the limiting plate by welding or other means, and the other end is a free end extending out of the fixing base 11. By pushing the rod portion upward, the limiting plate can be driven to move upward, so as to eject the shaping base 20 and the button cell 100, and realize the collection and arrangement of the button cell 100. The structure of the whole fixing member 10 is simple and convenient to operate, which is beneficial to industrial production.
