Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a button-type battery sealing device. Background Art

[0002] A button-type battery consists of a housing and a top cover. When the top cover is placed on the housing, a circular opening forms where the two meet, requiring a sealing device to close the opening. The sealing operation involves a robotic arm placing the assembled button-type battery into the lower mold's loading slot, then pressing the upper mold downward to squeeze the ring-shaped opening closed.

[0003] When the robot places the button battery into the lower mold, the button battery is in a free-fall state when entering the loading slot. In addition, the peripheral edge of the loading slot is designed with a chamfered structure, which often causes the battery to be inaccurately positioned and offset in the loading slot. In this case, pressing down the upper mold to seal it will cause the battery to be scrapped and the upper mold will also be stuck. Utility Model Content

[0012] Furthermore, the button battery sealing device also includes a guide rail, a slide and a second cylinder. The guide rail is fixed to the bracket, the slide is fixed to the movable seat, the slide and the guide rail are slidably matched, the second cylinder is installed on the bracket, and the second cylinder drives the movable seat to move back and forth.

[0013] Furthermore, the button battery sealing device also includes two positioning structures, which are respectively arranged at both ends of the moving path of the movable seat; when the movable seat abuts against one positioning structure, the lower mold moves to the material receiving position, and when the movable seat abuts against the other positioning structure, the lower mold moves to the sealing position.

[0014] Furthermore, the positioning structure includes a positioning seat, a positioning rod and a positioning head. The positioning seat is fixed to the bracket. The positioning rod and the positioning seat are threadedly connected to adjust the relative position. The positioning head is arranged at one end of the positioning rod. The end face of the positioning head cooperates with the end face stop of the movable seat.

[0015] Furthermore, the upper mold has an upper through hole, and the button battery sealing device also includes a demoulding shaft, which is lifted and lowered through the upper through hole and is used to press the button battery located in the bearing groove.

[0016] Furthermore, the button battery sealing device also includes an upper guide sleeve and a third cylinder.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 5 As shown, an embodiment of the present invention provides a button battery sealing device, including a lower mold 10, an adsorption assembly 20 and an upper mold 30. The lower mold 10 has a supporting groove 11 and a lower through-hole 12 that are interconnected. The diameter of the lower through-hole 12 is smaller than the diameter of the supporting groove 11, and the lower through-hole 12 is located below the supporting groove 11; the adsorption assembly 20 can be raised and lowered to pass through the lower through-hole 12, and the upper end of the adsorption assembly 20 can extend out of the supporting groove 11 to receive and adsorb the button battery. After the upper end of the adsorption assembly 20 descends, the adsorbed button battery is left in the supporting groove 11; the upper mold 30 can be raised and lowered, and the upper mold 30 and the lower mold 10 cooperate to close the annular opening of the button battery by squeezing.

[0039] In this solution, since a liftable adsorption component 20 is provided, when the button battery is placed in the supporting groove 11 of the lower mold, the upper end of the adsorption component 20 extends above the supporting groove 11 to adsorb the button battery, and then the adsorption component 20 drives the button battery down into the supporting groove 11. This replaces the existing method of button batteries falling into the supporting groove 11 by free fall. In this method, during the placement of the button battery, the button battery is smoothly moved down into the supporting groove 11 under the support of the adsorption component 20, and the position is accurate, thereby avoiding the problem of button battery displacement and improving the product yield of the sealing operation.

[0040] like Figure 2 and Figure 3 As shown, the suction assembly 20 includes a suction head 21 and a lifting rod 22. The lifting rod 22 is a hollow structure. The suction head 21 is mounted on the top of the lifting rod 22. The lifting rod 22 is connected to a negative pressure source, and the suction head 21 uses the negative pressure to attract the button battery. The lifting rod 22 drives the suction head 21 to move. When the suction head 21 is connected to the negative pressure source, the suction head 21 attracts the button battery. When the suction head 21 is disconnected from the negative pressure source, the suction head 21 releases the button battery.

[0041] In other embodiments not shown, the adsorption component 20 may adopt an electromagnetic adsorption structure. When the power is on, the adsorption component 20 generates magnetic force to adsorb the button battery, and when the power is off, the magnetic force disappears.

[0042] Furthermore, the suction assembly 20 also includes a lower guide sleeve 23 and a first cylinder 24. The lower guide sleeve 23 is located below the lower mold 10. The lifting rod 22 passes through the lower guide sleeve 23, and the first cylinder 24 drives the lifting rod 22 up and down. The action of the first cylinder 24 drives the lifting rod 22 and the suction head 21 up and down, and the lower guide sleeve 23 guides the lifting rod 22, ensuring smooth movement.

[0043] like Figure 2 and Figure 4 As shown, the button battery sealing device also includes a bracket 40 and a movable seat 51. The lower mold 10 and the adsorption assembly 20 are both installed on the movable seat 51. The movable seat 51 is movably installed on the bracket 40. The lower mold 10 has a sealing position located directly below the upper mold 30 and a material receiving position located outside the sealing position. The lower mold 10 and the adsorption assembly 20 receive the button battery at the material receiving position, and the movable seat 51 drives the lower mold 10 to switch positions.

[0044] This allows the lower mold 10 to be positioned so that when a button battery is inserted, the lower mold 10 is positioned outside the sealing position, preventing obstruction by structures such as the upper mold 30. After the button battery is inserted, the movable base 51 moves the lower mold 10 to the sealing position, where it cooperates with the upper mold 30 to perform the sealing operation.

[0045] During the movement of the lower mold 10, the suction assembly 20 moves along with the lower mold 10. To prevent the button battery from shifting due to shaking during the movement of the lower mold 10, the suction assembly 20 maintains suction on the button battery during the movement, thereby limiting the position of the button battery in the lower mold 10 and preventing it from shaking, ensuring accurate positioning.

[0046] like Figure 4 As shown, the button battery sealing device also includes a guide rail 52, a slide 53, and a second cylinder 54. The guide rail 52 is fixed to the bracket 40, and the slide 53 is fixed to the movable base 51. The slide 53 and the guide rail 52 slide together. The second cylinder 54 is mounted on the bracket 40 and drives the movable base 51 to move back and forth. The cooperation between the guide rail 52 and the slide 53 allows the movable base 51 to move back and forth smoothly.

[0047] In this solution, the button battery sealing device also includes two positioning structures 60, which are respectively arranged at both ends of the moving path of the movable seat 51; when the movable seat 51 abuts against one positioning structure 60, the lower mold 10 moves to the material receiving position, and when the movable seat 51 abuts against the other positioning structure 60, the lower mold 10 moves to the sealing position.

[0048] The positioning structure 60 ensures that the lower mold 10 can be accurately moved to the material receiving position or the sealing position, avoiding position deviation, which is conducive to realizing automated production. The lower mold 10 cooperates with the feeding robot at the material receiving position and cooperates with the upper mold 30 at the sealing position.

[0049] Specifically, the positioning structure 60 includes a positioning seat 61, a positioning rod 62 and a positioning head 63. The positioning seat 61 is fixed to the bracket 40. The positioning rod 62 and the positioning seat 61 are threadedly connected to adjust the relative position. The positioning head 63 is arranged at one end of the positioning rod 62, and the end face of the positioning head 63 cooperates with the end face stop of the movable seat 51.

[0050] That is, the end face of the positioning head 63 cooperates with the end face stop of the movable seat 51 to achieve the position limitation of the movable seat 51, thereby accurately limiting the position of the lower mold 10. The positioning rod 62 and the positioning seat 61 are threadedly connected to adjust the position of the positioning head 63 to eliminate assembly errors.

[0051] like Figure 3 and Figure 5 As shown, the upper mold 30 has an upper through-hole 31. The button battery sealing device also includes a demolding shaft 71, which is movably disposed through the upper through-hole 31 and is used to press the button battery in the supporting groove 11. The demolding shaft 71 is used to press the button battery during the sealing process, ensuring that the button battery does not move during the sealing process and ensuring the sealing quality.

[0052] Specifically, after the lower mold 10 moves directly below the upper mold 30, the ejector shaft 71 moves downward to press the button battery to position it, and then the suction assembly 20 releases the suction on the button battery. The upper mold 30 then presses down to seal the button battery. After sealing is completed, the ejector shaft 71 remains stationary, continuing to press the button battery while the upper mold 30 moves upward, separating the button battery from the upper mold 30. This prevents the button battery from becoming stuck in the upper mold 30 and becoming unable to separate from it. After the button battery is separated from the upper mold 30, the ejector shaft 71 moves upward again.

[0053] The demolding shaft 71 comprises a demolding rod and a pressing head. The demolding rod passes through the upper through-hole 31, and the pressing head is fixed to the lower end of the demolding rod. The demolding rod is arranged to be raised and lowered to drive the pressing head. The pressing head is used to press the button battery. The pressing head is made of a corrosion-resistant non-metallic material to avoid damaging the button battery.

[0054] like Figure 1 and Figure 5 As shown, the button battery sealing device also includes an upper guide sleeve 72 and a third cylinder 73. The upper guide sleeve 72 is located above the upper mold 30, and the demolding shaft 71 passes through the upper guide sleeve 72. The third cylinder 73 is connected to the upper end of the demolding shaft 71 to drive the demolding shaft 71 up and down. The third cylinder 73 drives the demolding shaft 71 up and down, and the upper guide sleeve 72 guides the demolding shaft 71, ensuring smooth elevation of the demolding shaft 71.

[0055] In this embodiment, the button battery sealing device further includes a support 40, a lifting base 81, a guide structure 82, and a drive structure 90. The upper mold 30 is fixed to the underside of the lifting base 81. The lifting base 81 is movably mounted to the support 40 via the guide structure 82. The drive structure 90 is mounted on the support 40 and drives the lifting base 81 up and down. This arrangement enables the upper mold 30 to be raised and lowered, thereby performing the sealing operation.

[0056] Specifically, if Figure 5 As shown, the driving structure 90 includes a support base 91, a transmission member 92 and a fourth cylinder 93. The support base 91 is fixed to the bracket 40. The middle part of the transmission member 92 is hinged to the support base 91. The first end of the transmission member 92 is movably connected to the lifting base 81. The second end of the transmission member 92 is movably connected to the fourth cylinder 93. The fourth cylinder 93 is installed on the bracket 40. The fourth cylinder 93 drives the second end of the transmission member 92 to rise and fall, and the first end of the transmission member 92 drives the lifting base 81 to rise and fall.

[0057] The above arrangement forms a lever structure, which can increase the pressure of the upper mold 30 while reducing the stroke of the fourth cylinder 93 and reducing the setting size of the fourth cylinder 93.

[0058] like Figure 1As shown, the button battery sealing device also includes a bracket 40, and the button battery sealing device includes two lower molds 10, two adsorption components 20 and two upper molds 30. The two upper molds 30 are spaced apart on both sides of the bracket 40, and the two lower molds 10 correspond to the two upper molds 30 one by one, and the two adsorption components 20 correspond to the two lower molds 10 one by one.

[0059] In this way, the button battery sealing device can perform sealing operations on two button batteries at two spaced positions respectively, thereby improving production efficiency.
