Description

Technical Field

[0001] The present application relates to the technical field of slicing devices, and in particular to a slicing machine for conductive gaskets. Background Art

[0002] The conductive gasket is composed of an elastic core and a conductive layer wrapped thereon. During the processing of the conductive gasket material, a slicer is usually used to cut the conductive gasket into required lengths.

[0003] The more common slicing method in the current process is to drop the cutting blade directly vertically and use pressure to cut off the conductive gasket. However, for some conductive gaskets with higher hardness, the greater pressure during the slicing process will wrinkle the conductive layer on the surface of the conductive gasket, and will also cause the conductive layer to have an uneven and jagged surface. These problems will lead to a low yield rate of the conductive gasket, seriously reducing production efficiency and increasing production costs. Utility Model Content

[0004] The purpose of the present application is to provide a slicer for conductive gaskets, so as to improve the technical problems that the conductive layer on the surface of the conductive gasket is wrinkled, the cutting edge of the conductive layer is uneven and jagged, and the yield rate of the conductive gasket is low when the existing slicer cuts the conductive gasket.

[0005] In the first aspect, an embodiment of the present application provides a slicer for a conductive gasket, comprising: a supporting platform for placing the conductive gasket, a cutting assembly, a first drive device and a second drive device, the cutting assembly comprising a blade, the blade having a blade edge, for cutting the conductive gasket placed on the supporting platform; the first drive device is connected to the blade and drives the blade to reciprocate along the extension direction of the blade; the second drive device is connected to the blade and is used to drive the blade to reciprocate up and down.

[0006] During the above implementation process, while the second driving device drives the blade to reciprocate up and down, the first driving device simultaneously drives the cutting assembly to reciprocate along the extension direction of the blade. When cutting the conductive gasket, the blade is first controlled to contact the conductive gasket downward, and then the first driving device causes the blade to reciprocate along its extension direction. The blade can move downward while grinding and cutting the conductive gasket, and the pressure can be reduced during cutting, thereby reducing the wrinkling of the conductive layer on the surface of the conductive gasket and the uneven and jagged surface of the conductive layer cut.

[0007] In a possible implementation, the first drive device includes a first driver and a first eccentric wheel, one end of the first driver is connected to the axis of the first eccentric wheel, the first eccentric wheel is connected to the blade, and the axis of the first eccentric wheel is perpendicular to the blade. The first driver drives the first eccentric wheel to rotate around the axis, and the axis of the eccentric wheel is not at the center of the circle, so the rotation of the first eccentric wheel drives the cutting assembly to reciprocate along the extension direction of the blade, thereby reciprocatingly cutting the conductive gasket along the extension direction of the blade.

[0008] In a possible implementation, the cutting assembly further includes a connecting plate, the blade is fixed to one end of the connecting plate, the end of the connecting plate away from the blade has a connecting hole, and a first mounting ring for mounting the first eccentric wheel is arranged in the connecting hole. The first eccentric wheel rotates in the first mounting ring, thereby driving the first mounting ring, the connecting plate, and the blade to reciprocate in an integral manner along the extension direction of the blade.

[0009] In a possible implementation, the second drive device includes a second driver, a second eccentric wheel and a connecting frame, one end of the second driver is connected to the axis of the second eccentric wheel, one end of the connecting frame is connected to the second eccentric wheel, the other end of the connecting frame is connected to the connecting plate, and the connecting plate is connected to the connecting frame in a sliding manner along the extension direction of the blade through a first sliding component, and the connecting frame is connected to the support platform in an up-and-down sliding manner through a second sliding component. The second driver drives the second eccentric wheel to rotate around the axis, and the axis of the eccentric wheel is not at the center of the circle, so the rotation of the second eccentric wheel drives the connecting frame, the connecting plate, and the blade to move up and down as a whole; at the same time, the connecting plate and the blade are guided by the first sliding component when they reciprocate in the extension direction of the blade as a whole, and are guided by the second sliding component when the connecting plate and the blade move up and down as a whole.

[0010] In a possible implementation, the connection frame is provided with a limiting hole, a second mounting ring for mounting the second eccentric wheel is provided in the limiting hole, and the second mounting ring is slidably connected to the hole wall of the limiting hole. The second eccentric wheel rotates in the second mounting ring, thereby driving the second mounting ring, the connection frame, the connection plate, and the blade to move up and down as a whole.

[0011] In a possible implementation, the connection hole is a strip hole, and the length direction of the strip hole is the up-down direction, and the first mounting ring is slidably connected to the hole wall of the strip hole. When the connection frame, the connection plate, and the blade are driven to move up and down as a whole, the first eccentric wheel and the first mounting ring can move up and down relatively in the strip hole.

[0012] In a possible implementation, the maximum distance between the axis of the second eccentric wheel and the circumference is smaller than the length of the connection hole, and the maximum distance between the axis of the second eccentric wheel and the circumference is matched with the maximum distance between the edge of the blade and the top surface of the support platform. The length of the connection hole can accommodate the amplitude of the up and down movement of the first eccentric wheel and the first mounting ring, and the amplitude of the up and down movement of the connecting frame, the connecting plate, and the blade driven by the rotation of the second eccentric wheel is matched with the maximum distance between the edge of the blade and the top surface of the support platform, so that the blade can cut the conductive gasket placed on the support platform.

[0013] In a possible implementation, an infrared sensor is disposed on the outer side of the connecting plate to sense the swing amplitude of the cutting assembly reciprocating along the extending direction of the blade, thereby preventing the cutting assembly from causing damage to the machine due to excessive swing amplitude of the reciprocating motion along the extending direction of the blade.

[0014] In a possible implementation, the slicer further includes a control device, which is electrically connected to the first drive device, the second drive device and the infrared sensor respectively, and controls the first drive device, the second drive device and the infrared sensor to work or stop.

[0015] In a possible implementation, the control device includes two servo drivers, a control panel, and an alarm light. One servo driver is electrically connected to the first driver, and the other servo driver is electrically connected to the second driver. The two servo drivers are electrically connected to the control panel respectively, and the infrared sensor is electrically connected to the alarm light. The control panel is electrically connected to the first driver and the second driver to control the operation of the first driver and the second driver. The servo driver is controlled by the control panel to adjust the motion position, motion speed, and motion torque of the first driver and the second driver. When the infrared sensor senses that the swing amplitude of the reciprocating motion of the cutting assembly along the extension direction of the blade is too large, it transmits information to light up the alarm light.

[0026] Example

[0027] The more common slicing method in the current process is to drop the cutting blade directly vertically and use pressure to cut off the conductive gasket. However, for some conductive gaskets with higher hardness, the greater pressure during the slicing process will wrinkle the conductive layer on the surface of the conductive gasket, and also cause the conductive layer to have an uneven and jagged surface at the cutting blade, resulting in unqualified cut conductive gaskets, which seriously reduces production efficiency and increases production costs.

[0028] The present application intends to improve the technical problems that the conductive layer on the surface of the conductive gasket is wrinkled, the cutting edge of the conductive layer is uneven and jagged, and the yield rate of the conductive gasket is low when the conductive gasket is cut by the existing slicer. A slicer for conductive gaskets is proposed, such as Figure 1 As shown, it includes: a supporting platform 1 for placing a conductive gasket, a cutting component 2, a first driving device 3 and a second driving device 4, the cutting component 2 includes a blade 21, the blade 21 has a blade edge, and is used to cut the conductive gasket placed on the supporting platform 1; the first driving device 3 is connected to the blade 21, and drives the blade 21 to reciprocate along the extension direction of the blade; the second driving device 4 is connected to the blade 21, and is used to drive the blade to reciprocate up and down.

[0029] The second drive device 4 drives the blade to reciprocate up and down. At the same time, the first drive device 3 drives the cutting assembly 2 to reciprocate along the extension direction of the blade. When cutting the conductive gasket, the blade is first controlled to contact the conductive gasket downward. Then, the first drive device causes the blade to reciprocate along its extension direction. The blade can move downward while grinding and cutting the conductive gasket. The pressure can be reduced during cutting, thereby reducing the wrinkling of the conductive layer on the surface of the conductive gasket and the uneven and jagged surface of the conductive layer cut.

[0030] In some embodiments, the first driving device 3 includes a first driver 31 and a first eccentric wheel 32, one end of the first driver 31 is connected to the axis of the first eccentric wheel 32, the first eccentric wheel 32 is connected to the blade 21, and the axis of the first eccentric wheel 32 is perpendicular to the blade. It should be noted that the axis of the first eccentric wheel 32 is not necessarily perpendicular to the blade at a standard 90°, and there may be some deviations, but it can be achieved that when rotating, the blade can be reciprocated along the extension direction of the blade. In other embodiments, the first driving device 3 can also use a cylinder or a motor and a screw. It can be achieved that the blade can be reciprocated along the extension direction of the blade.

[0031] like Figure 2As shown, the cutting assembly 2 also includes a connecting plate 22, the blade 21 is fixed to one end of the connecting plate 22, and the end of the connecting plate 22 away from the blade 21 has a connecting hole 221, and a first mounting ring 33 for mounting the first eccentric wheel 32 is arranged in the connecting hole 221. The first driver 31 drives the first eccentric wheel 32 to rotate around the axis core, and the first eccentric wheel 32 rotates in the first mounting ring 33. The axis center of the eccentric wheel is not at the center of the circle. Therefore, the rotation of the first eccentric wheel 32 drives the first mounting ring 33, the connecting plate 22, and the blade 21 to reciprocate in the extension direction of the blade; when the maximum distance between the axis center of the first eccentric wheel 32 and the circumference of the wheel rotates to the left, the first mounting ring 33, the connecting plate 22, and the blade 21 are driven to move in the left extension direction of the blade. When the maximum distance between the axis center of the first eccentric wheel 32 and the circumference of the wheel rotates to the right, the first mounting ring 33, the connecting plate 22, and the blade 21 are driven to move in the right extension direction of the blade. The circular rotation realizes the reciprocating movement of the first mounting ring 33, the connecting plate 22, and the blade 21 in the extension direction of the blade.

[0032] Specifically, the first driver 31 is a motor, and the output shaft of the motor is connected to the axis of the first eccentric wheel 32. The output shaft of the motor is perpendicular to the blade. It should be noted that the output shaft of the motor is not necessarily perpendicular to the blade at a standard 90°, and there may be some deviations, but when the output shaft of the motor drives the first eccentric wheel 32 to rotate, the blade can be reciprocated along the extension direction of the blade. The motor can be fixed on a motor bracket. It should be noted that in other embodiments, the motor can be fixed according to actual needs, and the motor can be fixed. This application does not limit the fixing method of the motor.

[0033] In some embodiments, the second driving device 4 includes a second driver (not shown in the figure), a second eccentric wheel 41 and a connecting frame 42, one end of the second driver is connected to the axis of the second eccentric wheel 41, one end of the connecting frame 42 is connected to the second eccentric wheel 41, the other end of the connecting frame 42 is connected to the connecting plate 22, and the connecting plate 22 is slidably connected to the connecting frame 42 along the extension direction of the blade through the first sliding component, and the connecting frame 42 is slidably connected to the supporting platform 1 up and down through the second sliding component. The connecting frame 42 is provided with a limited hole, and a second mounting ring 421 for mounting the second eccentric wheel 41 is provided in the limited hole, and the second mounting ring 421 is slidably connected to the hole wall of the limited hole. In other embodiments, the second driving device 4 can also adopt a cylinder or a motor and a screw. It can be achieved that the blade can reciprocate up and down.

[0034] The second driver drives the second eccentric wheel 41 to rotate around the axis core, and the second eccentric wheel 41 rotates in the second mounting ring 421. The axis center of the eccentric wheel is not at the center of the circle. Therefore, the rotation of the second eccentric wheel 41 drives the second mounting ring 421, the connecting frame 42, the connecting plate 22, and the blade 21 to reciprocate up and down as a whole; when the maximum distance between the axis center of the second eccentric wheel 41 and the circumference of the wheel rotates to the upper side, the second mounting ring 421, the connecting frame 42, the connecting plate 22, and the blade 21 are driven to move upward to the highest point as a whole. When the maximum distance between the axis center of the second eccentric wheel 41 and the circumference of the wheel rotates to the lower side, the second mounting ring 421, the connecting frame 42, the connecting plate 22, and the blade 21 are driven to move downward to the lowest point as a whole. The circular rotation realizes the driving of the second mounting ring 421, the connecting frame 42, the connecting plate 22, and the blade 21 to reciprocate up and down as a whole. At the same time, the connecting plate 22 and the blade 21 are slidably guided by the first sliding assembly when they reciprocate in the extending direction of the blade as a whole, and are slidably guided by the second sliding assembly when they move up and down as a whole.

[0035] Specifically, the second driver is a motor. The motor can be fixed on a motor bracket. It should be noted that in other embodiments, the motor can be fixed according to actual needs, and the motor can be fixed. The present application does not limit the fixing method of the motor. Specifically, the first sliding assembly and the second sliding assembly can be slide rails. In other embodiments, the first sliding assembly and the second sliding assembly can also be other structures that can achieve sliding. The second sliding assembly can be arranged on both sides of the support platform 1, or on another fixing member, and the connecting frame 42 can be slid up and down relative to the support platform 1 through the second sliding assembly. The present application does not limit the fixing method of the second sliding assembly.

[0036] In some embodiments, the connection hole 221 is a strip hole, and the length direction of the strip hole is the up-down direction, and the first mounting ring 33 is slidably connected to the hole wall of the strip hole. Among them, the maximum distance between the axis of the second eccentric wheel 41 and the wheel circumference is less than the length of the connection hole 221, and the maximum distance between the axis of the second eccentric wheel 41 and the wheel circumference is adapted to the maximum distance between the edge of the blade and the top surface of the carrier 1. When the second driver drives the connection frame 42, the connection plate 22, and the blade 21 to move up and down as a whole, the first eccentric wheel 32 and the first mounting ring 33 can move up and down in the strip hole relatively. The length of the connection hole 221 can accommodate the amplitude of the up-down movement of the first eccentric wheel 32 and the first mounting ring 33, and the second eccentric wheel 41 rotates to drive the second mounting ring 421, the connection frame 42, the connection plate 22, and the blade 21 to move up and down as a whole, and the amplitude of the up-down movement of the second eccentric wheel 41 and the second mounting ring 421, the connection frame 42, the connection plate 22, and the blade 21 is adapted to the maximum distance between the edge of the blade and the top surface of the carrier 1, so that the blade can cut the conductive pad placed on the carrier 1.

[0037] In some embodiments, the carrier 1 can be a rectangular parallelepiped structure, and the top surface of the carrier 1 is a plane, on which the conductive gasket can be placed directly. In order to cut the conductive gasket more accurately, a clamp for fixing the conductive gasket can be provided on the carrier 1. In other embodiments, the carrier 1 can have a through groove for placing the conductive gasket in the horizontal direction, and a notch is provided on the top surface of the carrier 1, which is connected to the through groove, and the notch extends along the direction of the blade, and the blade can cut the conductive gasket placed in the through groove through the notch. In order to further improve work efficiency, the through groove is arranged along the front-to-back direction of the carrier 1, and a conveying member is arranged in the through groove, so that the conductive gasket can be conveyed while being cut, and the cut and separated conductive gasket is conveyed out of the through groove.

[0038] In some embodiments, an infrared sensor 5 is provided on the outside of the connecting plate 22. The slicer also includes a control device 6, which is electrically connected to the first drive device 3, the second drive device 4 and the infrared sensor 5 respectively. The control device 6 includes two servo drivers 61, a control panel 62 and an alarm light 63, one servo driver 61 is electrically connected to the first drive device 3, the other servo driver 61 is electrically connected to the second drive device 4, the two servo drivers 61 are electrically connected to the control panel 62 respectively, the control panel 62 is electrically connected to the first drive device 3 and the second drive device 4, and the infrared sensor 5 is electrically connected to the alarm light 63. Specifically, the control panel 62 is electrically connected to the first driver 31 and the second driver, one servo driver 61 is electrically connected to the first driver 31, and the other servo driver 61 is electrically connected to the second driver.

[0039] When working, the machine is turned on by operating the control panel 62, and the two servo drivers 61 and the first driver 31 and the second driver are started. After the first driver 31 is started, it drives the first eccentric wheel 32 to rotate, thereby driving the first mounting ring 33, the connecting plate 22, and the blade 21 to reciprocate in the extension direction of the blade; the movement position, movement speed and movement torque of the first driver 31 are adjusted by a servo driver 61 to adjust the swing amplitude, reciprocating frequency, etc. of the reciprocating motion of the blade 21 in the extension direction of the blade; at the same time, after the second driver is started, it drives the second eccentric wheel 41 to rotate, thereby driving the second mounting ring 421, the connecting frame 42, the connecting plate 22, and the blade 21 to reciprocate up and down in an integrated manner; the movement position, movement speed and movement torque of the second driver are adjusted by another servo driver 61 The torque is used to adjust the swing amplitude, reciprocating frequency, etc. of the up and down reciprocating motion of the blade 21; so that the blade can reciprocate and reciprocate up and down in the extension direction of the blade at the same time, and reciprocate along the extension direction of the blade while cutting the conductive gasket, so that the blade can move downward while grinding and cutting the conductive gasket; if the swing amplitude of the reciprocating motion of the cutting component 2 in the extension direction of the blade is too large, the infrared sensor 5 senses the signal that the swing amplitude of the reciprocating motion of the cutting component 2 in the extension direction of the blade is too large, and transmits information to make the alarm light 63 light up to alarm, at this time, the servo driver 61 can be controlled by the operation control panel 62 to adjust the movement position of the first driver 31, so as to adjust the swing amplitude of the reciprocating motion of the cutting component 2 in the extension direction of the blade, so as to avoid damage to the machine caused by excessive swing amplitude.

[0040] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
