Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0027] like Figures 1 to 7 As shown, an embodiment of the present invention provides a multi-station conductive foam cutting device, including a base 1, a support and guide assembly 5 is fixedly provided on the top of the base 1, a stacking frame 2 and a cutting action piece 3 are respectively provided above the support and guide assembly 5, the bottom of the stacking frame 2 is provided with a movable support assembly 6 elastically sleeved on the support and guide assembly 5, a movable workbench 7 located on the side of the movable support assembly 6 is slidably sleeved on the support and guide assembly 5, a driving and moving mechanism 10 is provided on the top of the base 1, and the driving and moving mechanism controls the lateral movement of the movable workbench 7, an elastically sleeved limiting grasping portion 11 is symmetrically provided on the top of the movable workbench 7, an auxiliary stabilizing plate 9 is provided above the support and guide assembly 5, and the movable workbench 7 moves back and forth along the bottom of the stacking frame 2, below the cutting action piece 3 and below the auxiliary stabilizing plate 9.

[0028] Embodiment 1: When in use, multiple groups of conductive sponges to be cut are stacked in the stacking frame 2, and the bottom layer of conductive sponges falls on the top of the movable support assembly 6. When cutting, the driving moving mechanism 10 is started, and the movable workbench 7 is first controlled to move from under the cutting action part 3 to under the stacking frame 2. As the movable workbench 7 slides along the support guide assembly 5, the movable support assembly 6 is first pushed out from the bottom of the stacking frame 2. As the spring 1 64 is compressed, the baffle 61 moves away from the bottom of the stacking frame 2, and the carrier 71 in the synchronous movable workbench 7 replaces the position of the baffle 61 and moves to the top of the stacking frame 2. The air pump 72 is started, and the air pump 72 inputs pressurized air into the connecting cavity 73. The air pressure inside the connecting cavity 73 increases, pushing the limit plate 111 in the limit grabbing part 11 to extend from the top of the carrier 71 The two extending limit plates 111 are symmetrically distributed on the outside of the bottom conductive sponge, driving the moving mechanism 10 to move in the opposite direction and reset, so that the movable workbench 7 grabs a group of conductive sponges through the limiting grasping part 11 and moves out along the bottom groove 4 at the bottom of the stacking frame 2. At the same time of moving out, the movable support component 6 elastically resets and re-supports to complete automatic material picking. After picking up the material, it moves to the bottom of the cutting action part 3 with the conductive sponge, and moves close to the left side below the cutting action part 3, starting the lifting action mechanism 32 to control the cutting knife 33 to move back and forth up and down, and completes step-by-step cutting in the process of the conductive sponge moving intermittently toward the right. As the cutting process progresses, the cut conductive sponge follows the carrier 71 to move to the bottom of the auxiliary stabilizing plate 9, and the cutting knife 33 cuts back and forth along the left end of the auxiliary stabilizing plate 9.

[0029] First, by utilizing the movable support assembly 6, the movable workbench 7, the limiting grabbing part 11 and the stacking frame 2, the movable support assembly 6 is coordinated with the stacking frame 2 to realize the stacking of the internal multi-layer conductive sponge plates, and after the movable workbench 7 is squeezed, the position switching of the movable workbench 7 and the movable support assembly 6 is realized, and the stacked conductive sponge is automatically grabbed in cooperation with the limiting grabbing part 11, and is moved to the cutting area for cutting, and the automatic loading area, cutting area and auxiliary stabilization area are coordinated to complete the rapid automatic loading processing under multi-station cutting, providing continuous cutting efficiency.

[0030] In addition, by utilizing the reciprocating movement of the movable workbench 7 and the limiting grasping part 11, the movable support component 6 is pushed open when moving to the left side, and the grasping of the conductive sponge is completed, and when it moves to the bottom of the cutting action part 3, the step-by-step cutting is completed, and after cutting, the external push plate is cooperated with the outside to directly push the conductive sponge out after cutting along the side of the top of the carrier 71, realizing multi-station continuous processing, completing automated continuous cutting operations, and improving production efficiency.

[0031] On the other hand, by utilizing the auxiliary stabilizing plate 9 provided above the support and guide assembly 5, and placing the auxiliary stabilizing plate 9 on one side of the cutting action part 3, when the movable workbench 7 drives the conductive sponge to advance intermittently and cooperates with the reciprocating cutting knife 33 to complete the cutting, it is ensured that the conductive sponge after the previous cut is restricted to the bottom of the auxiliary stabilizing plate 9, and cooperates with the limiting treatment of the limiting plates 111 on both sides to ensure that the conductive sponge after cutting maintains good contact with the uncut conductive sponge, thereby realizing the stable treatment of the conductive sponge during the continuous cutting process, avoiding the jumping and deviation of the conductive sponge after cutting, causing the uncut conductive sponge to lose the limiting support function and deviate, thereby comprehensively improving the stability during actual continuous cutting.

[0032] The stacking frame 2 is fixedly connected to the base 1 via a connecting rod. A bottom groove 4 is provided at the bottom of the stacking frame 2 , and the bottom groove 4 is adapted to the movable workbench 7 .

[0033] By utilizing the bottom groove 4 to adapt to the sleeve movement of the carrier 71 and the limiting plate 111, the conductive foam is ensured to be limited and grasped.

[0034] Among them, the cutting action part 3 includes a support arm 31, a lifting action mechanism 32 and a cutting knife 33. The support arm 31 is fixed to the side of the stacking frame 2, the lifting action mechanism 32 is fixed to the bottom of the support arm 31, and the cutting knife 33 is fixed to the bottom of the lifting action mechanism 32.

[0035] The lifting mechanism 32 can be an electric or start-up push rod to achieve reciprocating lifting control, so that the cutting knife 33 can cut the conductive foam.

[0036] Among them, the support and guide assembly 5 includes a support plate 51, a support column 52 and a fixing rod 53. The support plate 51 and the support column 52 are symmetrically fixed on the top of the base 1, and the fixing rod 53 is fixedly connected between the support plate 51 and the support column 52.

[0037] The support and guide assembly 5 provides support and guidance for the reciprocating movement of the movable support assembly 6 and the movable workbench 7 to avoid deviation.

[0038] Among them, the movable support assembly 6 includes a baffle 61, a top plate 62, a side block 63 and a spring 64. The side block 63 is symmetrically fixed on the front and back of the baffle 61, the top plate 62 is fixed on the left side of the top of the baffle 61, one end of the spring 64 is fixedly connected to the side block 63, and the other end of the spring 64 is fixedly connected to the support plate 51.

[0039] By utilizing the elasticity of spring 1 64, it is compressed during squeezing and quickly reset when the carrier 71 moves out from the bottom of the stacking frame 2. The top plate 62 and the baffle 61 cooperate to achieve a stable position of the conductive sponge at the bottom of the stack.

[0040] Among them, the movable workbench 7 includes a carrier 71, an air pump 72 and a connecting chamber 73. The air pump 72 is fixed to the bottom of the carrier 71 through a bracket. The connecting chamber 73 is opened inside the carrier 71. The air outlet end of the air pump 72 is connected to the connecting chamber 73. The outer side of the carrier 71 is provided with a connecting frame 8, which is movably connected to the fixed rod 53. The limiting grasping part 11 includes a limiting plate 111, a second spring 112 and a sealing frame 113. The top of the connecting chamber 73 passes through the top of the carrier 71. The limiting plate 111 is movably connected in the connecting chamber 73. One end of the second spring 112 is fixedly connected to the limiting plate 111, and the other end of the second spring 112 is fixedly connected in the connecting chamber 73. The sealing frame 113 is fixedly nested in the connecting chamber 73, and the sealing frame 113 is movably connected to the limiting plate 111.

[0041] By utilizing the movable workbench 7 and the limiting grabbing part 11, the conductive sponge can be grabbed and supported. The hidden limiting grabbing part 11 that can be moved up and down remains hidden before grabbing to avoid pushing the conductive sponge, and cooperates with the limiting plates 111 on both sides to ensure that the conductive sponge moves stably with the carrier 71, while maintaining stability during cutting, avoiding sliding of the conductive sponge, and ensuring that the conductive sponge is limited in the grabbing area for stable cutting.

[0042] Among them, the driving movement mechanism 10 is a screw mechanism, which includes a driving motor and a driving screw, and the driving screw is threadedly connected to the connecting frame 8. The driving motor drives the driving screw to rotate and controls the lateral movement of the connecting frame 8.

[0043] The working principle and use process of the present invention are as follows: when in use, multiple groups of conductive sponges to be cut are stacked in the stacking frame 2, and the bottom layer of conductive sponges falls on the top of the movable support assembly 6. When cutting, the driving moving mechanism 10 is started, and the movable workbench 7 is first controlled to move from under the cutting action part 3 to under the stacking frame 2. As the movable workbench 7 slides along the support guide assembly 5, the movable support assembly 6 is first pushed out from the bottom of the stacking frame 2. As the spring 1 64 is compressed, the baffle 61 moves away from the bottom of the stacking frame 2, and the carrier 71 in the synchronous movable workbench 7 replaces the position of the baffle 61 and moves to the top of the stacking frame 2. The air pump 72 is started, and the air pump 72 inputs pressurized air into the connecting cavity 73. The air pressure inside the connecting cavity 73 increases, pushing the limit plate 111 in the limit grabbing part 11 out of the carrier 7 1 extends from the top, and the two extended limit plates 111 are symmetrically distributed on the outside of the bottom conductive sponge, driving the moving mechanism 10 to move in the opposite direction and reset, so that the movable workbench 7 grabs a group of conductive sponges through the limit grabbing part 11 and moves out along the bottom groove 4 at the bottom of the stacking frame 2. While moving out, the movable support component 6 elastically resets and re-supports to complete automatic material picking. After picking up the material, it moves to the bottom of the cutting action part 3 with the conductive sponge and moves close to the left side of the bottom of the cutting action part 3. The lifting action mechanism 32 is started to control the cutting knife 33 to move up and down reciprocatingly, and completes step-by-step cutting in the process of the conductive sponge intermittently moving toward the right. As the cutting process progresses, the cut conductive sponge follows the carrier 71 to move to the bottom of the auxiliary stabilizing plate 9, and the cutting knife 33 cuts reciprocatingly along the left end of the auxiliary stabilizing plate 9.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
