[0043] The utility model embodiment provides a sheet material holding mechanism,

[0044] A support 1, one end of which is provided with a first elastic component 11;

[0045] A rocker 2 extends in the length direction, the rocker 2 is rotatably connected to the support 1, one end of the rocker 2 is connected to the first elastic component 11, and the other end of the rocker 2 is provided with a suction head component 12, and the suction head component 12 is used to suck or release the sheet;

[0046] A pressure plate, which is arranged on a side of the rocker 2 away from the support 1 and is close to or away from the support 1 in the height direction;

[0047] When the pressing plate is close to the support 1, the pressing plate can make one end of the rocker 2 close to the support 1 and the other end of the rocker 2 away from the support 1;

[0048] When the pressure plate is away from the support 1 , the first elastic component 11 causes one end of the rocker 2 to be away from the support 1 and the other end of the rocker 2 to be close to the support 1 .

[0049] The present application can be used in the field of laminated capacitors to hold or release laminated welding machine foil. In a specific embodiment, as shown in the figure, the middle section of the rocker 2 is rotatably connected to the support 1, the left end of the rocker 2 is provided with the suction head assembly 12, the right end and the support 1 are provided with the first elastic assembly 11, and the upper right end is provided with the pressure plate (not shown).

[0050] When the pressing plate moves upward, the right end of the rocker 2 moves upward and the left end moves downward under the action of the first elastic component 11, and at this time, the suction head component 12 on the left end sucks the sheet;

[0051] When the pressing plate moves downward, the right end of the rocker 2 moves downward close to the support 1, and the suction head assembly 12 at the left end moves upward. At this time, the suction head assembly 12 can drive the sheet to move upward and then release the sheet.

[0052] The rocker 2 is rotatably connected to the support 1. In a specific embodiment, as shown in the figure, the support 1 is provided with a through slot 13, the through slot 13 extends along the length direction, and the rocker 2 is arranged in the through slot 13;

[0053] The support 1 also includes:

[0054] A rotating shaft 14 extends along the width direction and is disposed in the through slot 13, and the rocker 2 is sleeved with the rotating shaft 14;

[0055] A first bearing 15 is disposed at one side of the through slot 13, and an inner ring of the first bearing 15 is sleeved with one end of the rotating shaft 14;

[0056] A second bearing 16 is arranged on the other side of the through groove 13, and the inner ring of the second bearing 16 is sleeved with the other end of the rotating shaft 14. This structural design is beneficial to the stability of the rocker 2 during rotation. Furthermore, the support 1 also includes a first mounting screw 17. A first assembly hole is provided on the support 1, and a first mounting hole is provided on the rotating shaft 14. The first mounting screw 17 passes through the first assembly hole and is threadedly connected to the first mounting hole. This structure avoids the position of the rotating shaft 14 from being offset, thereby ensuring the stability of the sheet holding mechanism during operation.

[0057] Furthermore, a first groove is provided on a side of the rocker 2 close to the support 1, and a second groove is provided on a side of the support 1 close to the rocker 2;

[0058] The first elastic component 11 includes a first spring, which extends in the height direction. One end of the first spring is disposed in the first slot body, and the other end of the first spring is disposed in the second slot body. The first spring is in a compressed state.

[0059] As shown in the figure, the upper end of the first spring is arranged in the first slot of the rocker 2, and the lower end is arranged in the second slot of the support 1. Since the first spring is in a compressed state, the first spring has a tendency to return to its original state, and thus in the initial state, the first spring can make the left end of the rocker 2 lower than the right end. During operation, the pressure plate moves downward, driving the right end of the rocker 2 to move downward and further compressing the first spring. When the pressure plate moves upward, the elastic force of the first spring drives the right end of the rocker 2 to move upward, and at the same time the left end of the rocker 2 moves downward, so that the rocker 2 can swing.

[0060] Furthermore, a pressing block assembly is further provided at one end of the rocker 2 close to the first elastic assembly 11, and the pressing block assembly includes:

[0061] The shaft body 21 extends along the length direction, part of the shaft body 21 is disposed in the rocker 2 and fixedly connected to the rocker 2, and another part of the shaft body 21 is disposed outside the rocker 2;

[0062] The pressing block 22 is arranged outside the rocker 2 and sleeved on the shaft 21 .

[0063] As shown in the figure, the connection method between the shaft body 21 and the rocker 2 is not limited. In a specific embodiment, the support 1 also includes a second mounting screw 18, the rocker 2 is provided with a second assembly hole, and the shaft body 21 is provided with a second mounting hole. The second mounting screw 18 passes through the second assembly hole and is threadedly connected to the second mounting hole, so that the shaft body 21 can be fixedly set on the right end of the rocker 2.

[0064] The pressing block 22 is sleeved on the shaft 21, which is conducive to the pressing plate pressing down the right end of the rocker 2. The shape of the pressing block 22 is not limited. Further, the shape of the pressing block 22 is a sphere, which can reduce the wear between the pressing block 22 and the pressing plate. Furthermore, the material of the pressing block 22 is steel, which is wear-resistant.

[0065] Furthermore, it also includes a second elastic component 3, wherein the second elastic component 3 includes:

[0066] A plug 31, the support 1 is provided with a through hole, the through hole extends in the width direction, the plug 31 passes through the through hole, the inner end of the plug 31 is closely attached to the rocker 2, and the outer end of the plug 31 is arranged outside the support 1;

[0067] A top cap 32 is sleeved on the outer end of the top cap 31 and is fixedly connected to the support 1;

[0068] The second spring 33 is disposed between the outer end of the plug 31 and the plug cap 32 , and the second spring 33 is in a compressed state.

[0069] As shown in the figure, when installing the sheet material holding mechanism, in order to make the rocker 2 arranged in the through slot 13 of the support 1, the width of the rocker 2 should be slightly smaller than the width of the through slot 13, so the rocker 2 is easy to deflect in the width direction when swinging. The second elastic component 3 is arranged on the side of the support 1. Since the top cap 32 is fixedly connected to the support 1, the second spring 33 is arranged between the top head 31 and the top cap 32, and the second spring 33 is in a compressed state, so that the second spring 33 has a tendency to restore to its original state, and generates a pre-tightening force on the top head 31, and can make the inner end of the top head 31 close to the rocker 2, ensuring that the rocker 2 is close to the inner wall of the channel when swinging, thereby avoiding the rocker 2 from deflecting in the width direction. This structure can ensure the stability of the rocker 2 during operation.

[0070] Furthermore, the second elastic component 3 also includes a positioning pin 34,

[0071] The outer end of the plug 31 is provided with a third groove body, and the third groove body extends along the width direction.

[0072] A fourth slot is provided on the inner side of the top cap 32, one end of the positioning pin 34 is provided in the third slot, and the other end of the positioning pin 34 is provided in the fourth slot;

[0073] The second spring 33 is sleeved on the positioning pin 34 .

[0074] In a specific embodiment, as shown in the figure, the positioning pin 34 can limit the position of the second spring 33 to prevent the second spring 33 from being offset, and the structure is stable.

[0075] Furthermore, the rocker 2 includes an extension portion, the extension portion is provided with a limiting through hole, and the limiting through hole penetrates the extension portion along the height direction.

[0076] The sheet material holding mechanism further comprises a limiting screw 4 , wherein the limiting screw 4 passes through the limiting through hole, and a limiting nut is provided on a side of the limiting screw 4 close to the support 1 .

[0077] As shown in the figure, when the pressure plate moves upward, the right end of the rocker arm 2 moves upward under the action of the first spring, and the left end of the rocker arm 2 moves downward. At this time, the limiting nut on the limiting screw can limit the downward extreme position of the left end of the rocker arm 2, ensuring that the suction head assembly 12 at the left end of the rocker arm 2 can reach the position where the sheet is located.

[0078] Furthermore, the suction head assembly 12 includes a suction head 121,

[0079] An air channel 122 is provided on the rocker 2 , one end of the air channel 122 is used to connect to a vacuum valve, and the other end of the air channel 122 is used to set the suction head 121 .

[0080] As shown in the figure, the air duct 122 is connected to the vacuum pump. During operation, when the left end of the rocker arm 2 moves downward, the vacuum pump is turned on, and the suction head 121 can suck the sheet. Then the pressure plate presses the pressure block 22 downward, so that the right end of the rocker arm 2 drops, and the left end of the rocker arm 2 rises and drives the sheet to the required height. At this time, the vacuum pump is turned off, and the suction head 121 releases the sheet to realize the suction operation of the sheet.

[0081] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
