Description

Technical Field This utility model relates to chip punching technology, and more particularly to a flexible strip punching device. Background Technology Currently, on the communication production line in the communication workshop, chip strips need to be initialized. During the initialization process, the chip strips that have not been written or have failed the test need to be identified by punching holes. Since the chip strips are usually distributed in two or three columns, if a fixed cylinder punching station is used, multiple punching stations need to be installed for different punching positions. This not only occupies too much equipment space, but also makes it difficult for the long-term stable operation of the equipment due to the poor precision of the cylinder-driven punch and the high noise during the operation. It may also cause subtle occupational injuries to the operators.

[0001] Moreover, existing chip punching and pressing devices are not very precise and have complex structures, making it difficult to ensure that the strip chip will not be displaced on the transport belt at the moment of punching. This can affect the flatness of the punching surface and cause adjacent good chips to be affected and damaged during punching. Utility Model Content This utility model provides a flexible strip punching device, which enables a single workstation to punch holes at different positions on a chip strip, effectively improving punching accuracy and preventing damage to the punch or punching the wrong chip.

[0002] The technical solution adopted by this utility model to solve its technical problem is: A flexible punching device for chip strips transported on a track is used to punch holes at different positions of chip strips. It includes a linear drive mechanism, a punch mechanism and an eccentric drive mechanism. The chip strip enters the upper and lower corresponding punching cavities of the punch mechanism along the track. The linear drive mechanism drives the punch mechanism to move laterally along the X-axis along the feed direction of the chip strip and controls the chip strip to move horizontally along the Y-axis under the track drive to adjust the punching positions of the chip on the chip strip. The eccentric drive mechanism is mounted on the lower side of the punch mechanism and drives the punches on the punch mechanism to punch holes at different positions on the chip strip.

[0003] Preferably, the eccentric drive mechanism includes a hanging plate frame, an eccentric stepper drive motor, an eccentric wheel, and an eccentric linkage plate. The hanging plate frame is suspended and fixed to the bottom side of the punch mechanism. The eccentric stepper drive motor is fixed to the side of the hanging plate frame via a connecting plate. The eccentric wheel is rotatably mounted on the lower side of the eccentric linkage plate via an eccentric bearing. The output shaft of the eccentric stepper drive motor is coaxially connected to the upper wheel shaft of the eccentric wheel and drives the eccentric linkage plate, which is located in the middle of the hanging plate frame, to move up and down. The eccentric linkage plate synchronously drives the punch on the punch mechanism to perform up and down punching actions.

[0004] Preferably, the punch mechanism includes a punch holder, an upper punching disc, a lower punching disc, multiple return springs, a punching cylinder, and a punching pressure plate. The punching cylinder is slidably mounted on the lower base plate of the punch holder. The punching pressure plate is fixed to the bottom end of the punching cylinder, and the bottom end of the punching pressure plate is hinged to the eccentric linkage plate on the eccentric drive mechanism via a connecting shaft. The lower punching disc is slidably mounted on the top end of the punching cylinder. A pair of punches for punching chips on the chip strip are installed at the center of the punching cylinder. Multiple return springs are evenly installed circumferentially between the lower side of the lower punching disc and the top end of the punching cylinder, and drive the upper side of the lower punching disc to be flush with the punches before punching. The upper punching disc is installed on the lower side of the upper top plate of the punch holder and is directly opposite the lower punching disc on the lower side. A punching channel for the chip strip to pass through is formed between the upper punching disc and the lower punching disc.

[0005] Preferably, the linear drive mechanism includes a linear stepper drive motor and a linear lead screw sliding assembly. The slider on the linear lead screw sliding assembly is connected and fixed to the punch holder of the punch mechanism through a support plate. The linear stepper drive motor drives the punch mechanism connected to the linear lead screw sliding assembly to move laterally along the X-axis for adjustment.

[0006] The beneficial effects of this utility model are: The existing punching equipment uses a fixed cylinder punching method, which requires the installation of multiple punching stations for different punching positions. Furthermore, the punching positions are different for different specifications of strips, requiring the removal and adjustment of the fixing screws to adjust the punching position. This method occupies too much equipment space, consumes a lot of time, and is cumbersome to operate, thus failing to effectively improve production efficiency.

[0007] In operation, the linear drive mechanism drives the punch mechanism to move laterally along the X-axis along the feed direction of the chip strip, while the track drive controls the chip strip to move horizontally along the Y-axis to adjust the punching positions of the chip on the chip strip. The eccentric drive mechanism drives the punches on the punch mechanism to punch different positions of the chip strip, realizing that one workstation can punch different positions of the chip strip. The punching process is more precise and stable, effectively improving the accuracy of punching and preventing the punches from being damaged or punching the wrong chip.

[0009] A flexible strip punching device, such as Figures 1 to 3 As shown, the punching mechanism for different positions of the chip strip 1 transported on the track includes a linear drive mechanism 2, a punch mechanism 3, and an eccentric drive mechanism 4. The chip strip 1 enters the corresponding punching cavities above and below the punch mechanism 3 along the track (not shown). The linear drive mechanism 2 drives the punch mechanism 3 to move laterally along the X-axis in the feed direction of the chip strip 1 and controls the chip strip 1 to move horizontally along the Y-axis under the drive of the track to adjust the punching of the chip at different punching positions on the chip strip 1. The linear drive mechanism 2 includes a linear stepper drive motor 20 and a linear lead screw sliding assembly 21. The slider on the linear lead screw sliding assembly 21 is connected and fixed to the punch holder 30 of the punch mechanism 3 through a support plate 5. The linear stepper drive motor 20 drives the punch mechanism 3 connected to the linear lead screw sliding assembly 21 to move laterally along the X-axis. The eccentric drive mechanism 4 is mounted on the lower side of the punch mechanism 3 and drives the punch on the punch mechanism 3 to punch different positions of the chip strip 1.

[0010] like Figures 1 to 3As shown, the eccentric drive mechanism 4 includes a hanging plate frame 40, an eccentric stepper drive motor 41, an eccentric wheel 42, and an eccentric linkage plate 43. The hanging plate frame 40 is suspended and fixed to the bottom side of the punch mechanism 3. The eccentric stepper drive motor is fixed to the side of the hanging plate frame 40 through a connecting plate. The eccentric wheel 42 is rotatably mounted on the lower side of the eccentric linkage plate 43 through an eccentric bearing 44. The output shaft of the eccentric stepper drive motor is coaxially connected to the upper wheel shaft 420 of the eccentric wheel 42 and drives the eccentric linkage plate 43, which is located in the middle of the hanging plate frame 40, to move up and down. The eccentric linkage plate 43 synchronously drives the punch on the punch mechanism 3 to perform up and down punching action.

[0011] like Figures 1 to 3 As shown, the punch mechanism 3 includes a punch holder 30, an upper punching disc 31, a lower punching disc 32, multiple return springs 33, a punching cylinder 34, and a punching pressure plate 35. The punching cylinder 34 is slidably mounted on the lower base plate of the punch holder 30. The punching pressure plate 35 is fixed to the bottom end of the punching cylinder 34, and the bottom end of the punching pressure plate 35 is hinged to the eccentric linkage plate 43 of the eccentric drive mechanism 4 via a connecting shaft 36. The lower punching disc 32 is slidably mounted on the top end of the punching cylinder 34. A pair of punches 37 for punching chips on chip strip 1 are installed at the center of 34. Multiple return springs 33 are evenly installed circumferentially between the lower side of the punching lower disk 32 and the top surface of the punching cylinder 34, and drive the upper side of the punching lower disk 32 to be flush with the punches 37 before punching. The punching upper disk 31 is installed on the lower side of the upper top plate of the punching base 30 and is directly opposite the punching lower disk 32 on the lower side. A punching channel for chip strip 1 to pass through is formed between the punching upper disk 31 and the punching lower disk 32.

[0012] In this embodiment, the linear drive mechanism 2 drives the punch mechanism 3 to move laterally along the X-axis along the feed direction of the chip strip 1. At the same time, under the track drive, the chip strip 1 is controlled to move horizontally along the Y-axis to adjust the punching position of the chip on the chip strip 1. After the chip strip 1 is adjusted to the corresponding punching position, the eccentric stepper drive motor 41 drives the eccentric wheel 42 to rotate. The eccentric wheel 42 drives the punch mechanism 3 to perform punching work. The punching operation process can be adjusted by changing the parameters of the eccentric stepper drive motor 41. When the eccentric wheel 42 drives the punching plate 35 to move upward through the eccentric linkage plate 43, the upper punching disc 31 contacts the lower punching disc 32, pressing and fixing the chip strip 1. Then, the reset spring 33 contracts to make the punch protrude, and punches the chip on the chip strip 1. After the punching process is completed, the spring returns, and the punch retracts into the lower punching disc 32, waiting for the next punching command. In the whole process, only one workstation is needed to punch different positions of the chip strip 1. The punching action is more precise and stable, effectively improving the accuracy of punching and preventing the punch from being damaged or punching the wrong chip.

All equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
