[0015] Figure 1 This is a schematic structural diagram from a first perspective of an automatic material pulling device according to an embodiment of the present invention.

[0016] Figure 2 This is a schematic structural diagram from a second perspective of an automatic material pulling device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0017] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] The utility model provides an automatic material pulling device, such as Figure 1-2As shown, an automatic material pulling device of one embodiment includes a positioning assembly 10, a guide assembly 20 and a material pulling drive 30. The positioning assembly 10 includes a first drive 11 and a positioning pin 12. The first drive 11 can drive the positioning pin 12 to move closer to or away from the material strip 70 to achieve a working state or a waiting state. The guide assembly 20 includes a slider 21 and a slide rail 22. The slider 21 is slidably connected to the slide rail 22. The slide rail 22 has a length extending along a first direction. The slider 21 is relatively fixedly connected to the first drive 11. The material pulling drive 30 can drive the slider 21 to move in the first direction. When the positioning pin 12 is in the working state, the positioning pin 12 is connected to the positioning hole on the material strip 70 in a convex-concave manner; after the positioning pin 12 completes its work, the first drive 11 drives the positioning pin 12 to move in a direction away from the material strip 70 to switch to the waiting state.

[0019] In the automatic material pulling device of the present invention, positioning is achieved by the positioning pin 12 of the positioning component 10 cooperating with the positioning hole on the material strip 70. The material pulling drive 30 drives the positioning component 10 to move to drive the material strip 70 to move, and combined with the precise guidance of the guide component 20, it can achieve accurate, smooth and fast material pulling of the material strip 70 after stamping, thereby improving production efficiency and product quality.

[0020] It should be noted that the first direction is the direction of travel of the material strip 70. The automatic material pulling device is used to pull the material strip 70 during the stamping process in the stamping die. After the stamping die completes a stamping process, the automatic material pulling device pulls the material strip 70 a certain distance, pulling the remaining portion of the material strip 70 that has not yet been stamped to the stamping station for stamping. After the stamping process is completed, the material strip 70 is pulled again and the above process is repeated.

[0021] For ease of description and understanding, the first direction is positioned as the left-right direction. It can be understood that when the automatic material pulling is switched to pulling the material belt 70 to move right, the moving direction of the material belt 70 is right.

[0022] In this embodiment, the end of positioning pin 12 can be tapered to facilitate insertion into the positioning hole of strip 70. When positioning pin 12 is in the active state, first drive member 11 drives positioning pin 12 toward strip 70, where it forms a convex-concave connection with the positioning hole on strip 70. Subsequently, the material pulling drive member 30 drives first drive member 11 to the right, synchronously pulling strip 70 to the right with positioning pin 12. After pulling a certain distance, first drive member 11 drives positioning pin 12 away from strip 70, switching to the standby state.

[0023] In this embodiment, the automatic material pulling device further includes two limiters 40 , which are respectively located at both ends of the slide rail 22 and are used to limit the position of the slider 21 moving in the length direction of the slide rail 22 .

[0024] Specifically, the distance between the two limiting members 40 is the length that the stamping die completes a stamping process on the material strip 70. After the stamping die completes the stamping process on one end of the material strip 70, the positioning assembly 10 works so that the positioning pin 12 cooperates with the positioning hole on the material strip 70 to complete the positioning, and the pulling drive 30 drives the positioning assembly 10 to move to the right until the positioning assembly 10 abuts against the limiting member 40 on the right and stops moving. It should be noted that the pulling drive 30 drives the positioning assembly 10 to move from the limiting member 40 on the left to the moving member on the right, and the distance the positioning assembly 10 moves is the distance between the two limiting members 40. The distance that the material strip 70 travels after a stamping process is the distance between the two limiting members 40.

[0025] In this embodiment, the automatic material pulling device also includes a cover plate 50, which is provided with a material guide groove 51. The material guide groove 51 has a length extending in the left and right directions. The material belt 70 is placed in the material guide groove 51, and the material belt 70 passes through the material guide groove 51. When the positioning needle 12 is in the working state, the material pulling drive 30 drives the slider 21 to drive the positioning assembly 10 to move in the first direction, and the positioning needle 12 of the positioning assembly 10 pulls the material belt 70 to move.

[0026] Specifically, the guide trough 51 is used to guide the direction of movement of the material strip 70, preventing the material strip 70 from shifting during its movement, preferably in the left-right direction. The width of the guide trough 51 is greater than or equal to the width of the material strip 70. Preferably, the width of the guide trough 51 is slightly greater than the width of the material strip 70, and a gap exists between the material strip 70 and the groove walls on both sides of the guide trough 51, reducing friction between the material strip 70 and the groove walls during movement.

[0027] In this embodiment, the cover plate 50 is provided with an escape hole 52 for the positioning pin 12 to pass through to approach or move away from the material strip 70. The escape hole 52 has a length extending in the left-right direction, and the length of the escape hole 52 is greater than or equal to the distance between the two stoppers 40.

[0028] In another preferred embodiment, there are two positioning pins 12, both fixedly mounted on a pin holder 13. The pin holder 13 is connected to the driving end of the first driving member 11. The first driving member 11 can drive the pin holder 13 toward or away from the cover plate 50, thereby driving the positioning pins 12 toward or away from the material strip 70. The two positioning pins 12 move toward the material strip 70 and respectively engage with the positioning holes on both sides of the material strip 70, allowing the material strip 70 to move more smoothly during the pulling process.

[0029] In this embodiment, the guide assembly 20 further includes a sliding seat 23, two slide rails 22, and two sliders 21. The two slide rails 22 are located on either side of the cover plate 50, and each slider 21 is slidably connected to a slide rail 22. The sliding seat 23 is fixedly connected to the two sliders 21, and the first drive member 11 is mounted and connected to the sliding seat 23. The provision of two sets of sliders 21 and slide rails 22, distributed on either side of the cover plate 50 (material strip 70), ensures smooth movement, reduces impact and vibration, and is less likely to cause creeping, thereby improving working accuracy.

[0030] In this embodiment, the automatic material pulling device further includes a material pressing assembly 60, which is used to press the material strip 70 to prevent it from loosening. Specifically, after the material strip 70 moves the required distance, the positioning pins 12 will move away from the material strip 70. During this process, the material pressing assembly 60 will press the material strip 70 to prevent the positioning pins 12 from separating from the positioning holes in the material strip 70 and lifting the material strip 70. At the same time, when the stamping die is stamping the material strip 70, the material pressing assembly 60 will press the material strip 70 tightly to prevent it from loosening and affecting the process effect.

[0031] Specifically, the pressing assembly 60 includes a second driving member 61 and a pressing member 62 . The second driving member 61 can drive the pressing member 62 to move closer to or away from the material belt 70 . The second driving member 61 drives the pressing member 62 to move closer to the material belt 70 to press the material belt 70 .

[0032] It should be noted that the first driving member 11, the second driving member 61 and the material pulling driving member 30 can all be air cylinders or oil cylinders, and in this embodiment, air cylinders are preferred.

[0033] In this embodiment, the positioning assembly 10 also includes a sensor for detecting the position of the positioning pin 12 when inserted into the positioning hole of the material strip 70 and feeding back a signal to the control unit. The control unit confirms the position of the positioning pin 12 based on the signal to prevent the positioning pin 12 from damaging the material strip 70 or breaking the material strip 70 due to incorrect positioning. The control unit is connected to the first drive member 11 and controls the extension, retraction, and start / stop of the first drive member 11 based on a preset program and the received sensor signal.

[0034] In this embodiment, the automatic material pulling device further includes a base 80 , and the positioning assembly 10 , the guide assembly 20 and the material pulling driving member 30 are all installed on the base 80 .

[0035] During operation, the control unit activates the material pull drive 30, which extends and drives the slide 23 toward the initial position of the material strip 70. The slide 23 stops when it contacts the left stop 40, and the sensor transmits a signal indicating the position is in place. The second drive 61 drives the pressure member 62 toward the material strip 70, pressing it and preventing it from moving left or right. The stamping die closes, and the locating pins in the die penetrate the locating holes in the material strip 70, sending a signal to the second drive 61 of the pressure assembly 60 to drive the pressure member 62 away from the material strip 70, relying on the die for precise positioning. The stamping die opens after completing the stamping process, and a signal is sent when the die positioning pin leaves the positioning hole of the material strip 70. The first driving member 11 of the positioning assembly 10 drives the positioning pin 12 to move toward the direction close to the material strip 70 and insert it into the positioning hole of the material strip 70. Then the pulling driving member 30 retracts, driving the sliding seat 23 to move to the right until it contacts the limit member 40 on the right and stops, pulling the material strip 70 out to the specified position.
