Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board production equipment, specifically relating to a punch press with automatic reversing punching capability. Background Technology

[0002] Currently, the flexible circuit boards used in the new energy industry are mostly long and symmetrically distributed, making the processing of these long flexible circuit boards quite challenging. There are generally two methods for processing such flexible circuit boards: one is to process both ends simultaneously, using a single machine to punch both ends of the flexible circuit board at the same time. This type of equipment is bulky, has high mold costs, and occupies a large space. Furthermore, since a large area in the middle of the product does not require punching, processing both ends simultaneously may cause the product itself to expand or contract, making it difficult to guarantee processing accuracy. The other method is to use a punch press to process one end of the flexible circuit board first, and then manually reverse the product to process the other end. Due to the length of the flexible circuit board, manual reversal is very inconvenient and difficult to position correctly. Summary of the Invention

[0003] In view of the problems existing in the prior art, the main purpose of this utility model is to provide a punch press that can automatically change direction for punching.

[0004] To achieve the above-mentioned main objectives, this utility model provides a stamping die assembly including a frame and a stamping die assembly installed in the frame. The stamping die assembly includes an upper die assembly that can move up and down and a lower die assembly that can move horizontally between a loading position and a stamping position. The stamping press includes a loading and unloading robot for placing the product to be stamped onto the lower die assembly located at the loading position, reversing the direction of the product that has been stamped at one end, and removing the stamped product.

[0005] As can be seen from the above solutions, the products to be punched can be placed by the loading and unloading robot, the products that have been punched at one end can be reversed, and the punched products can be taken away without manual intervention, which can facilitate reversal and positioning.

[0006] According to a specific embodiment of this utility model, the loading and unloading robot includes a Y-axis moving module that can move horizontally along the Y-axis direction, wherein the Y-axis direction is perpendicular to the moving direction of the lower mold assembly. Two Y-axis moving tracks are arranged on the frame to guide the movement of the Y-axis moving module, respectively supporting both ends of the Y-axis moving module and guiding it to move horizontally along the Y-axis. A rotating module is provided on the Y-axis moving module. An X-axis horizontal moving track is provided on the rotating module. A first X-axis moving module and a second X-axis moving module that can move horizontally along the X-axis moving track are provided on the X-axis horizontal moving track. A first Z-axis moving module is provided on the first X-axis moving module, and a second X-axis moving module is provided on the second X-axis moving module. The second Z-axis moving module has a first gripping mechanism and a second gripping mechanism respectively mounted on the first Z-axis moving module and the second Z-axis moving module, and can move independently along the X-axis and Z-axis directions. The rotating module also has a third Z-axis moving module, which is fixedly mounted between the first Z-axis moving module and the second Z-axis moving module and has a third gripping mechanism. The first gripping mechanism, the second gripping mechanism and the third gripping mechanism can perform gripping and releasing actions independently. When the loading and unloading robot grips the product to be punched, the first gripping mechanism and the second gripping mechanism grip the two ends of the product to be punched, and the third gripping mechanism grips the middle part of the product to be punched.

[0007] As can be seen from the above scheme, by moving horizontally along the Y-axis moving track, the loading and unloading robot can grasp and transfer products. By setting up the rotating module, the direction of the product to be punched can be changed. By moving the first X-axis moving module and the second X-axis moving module along the X-axis moving track, the length of the product to be punched in the horizontal direction can be extended or retracted. By moving the three Z-axis moving modules independently in the vertical direction, the ungrabbed part of the product is kept flat during extension and retraction, so that the product is not easily deformed.

[0008] According to a specific embodiment of this utility model, a first positioning camera is provided on the first X-axis moving module, and a second positioning camera is provided on the second X-axis moving module. The first positioning camera and the second positioning camera are used to position the two ends of the product to be processed for punching, so as to accurately position and precisely punch.

[0009] According to a specific embodiment of this utility model, the first gripping mechanism is a first suction cup, the second gripping mechanism is a second suction cup, and the third gripping mechanism is a third suction cup. Each suction cup includes multiple suction nozzles whose relative positions are movable. The relative positions of the multiple suction nozzles can be adjusted according to the specific dimensions of the product to be punched.

[0010] According to a specific embodiment of this utility model, the lower die assembly includes a lower die and a die platform detachably connected to the lower die. A waste material receiving portion is provided on the die platform, into which the punched waste material falls. Waste material is collected through the waste material receiving portion.

[0011] According to a specific embodiment of this utility model, the mold platform includes a cover plate with a handle. The cover plate can be opened via the handle to expose the waste material receiving portion. By opening the waste material receiving portion via the handle, the waste material contained therein can be removed.

[0012] According to a specific embodiment of this utility model, the punch press further includes a carrier receiving section, and the loading / unloading robot moves the carrier after transferring the products to be punched to the carrier receiving section. The carrier is collected through the carrier receiving section.

[0013] According to a specific embodiment of this utility model, the punch press further includes a discharge conveyor track. After punching is completed, the loading and unloading robot places the punched product onto the discharge conveyor track. The punched product is output via the discharge conveyor track.

[0014] According to a specific embodiment of this utility model, the punch press is provided with a loading platform, which can move between a product placement position and a product to be gripped position. The product placement position can be located outside the punch press to facilitate the placement of the product to be punched.

[0015] According to a specific embodiment of this utility model, the loading platform further includes a vertical moving component, enabling the loading platform to move vertically. The height of the loading platform can be adjusted according to the stacking height of the products to be punched.

[0016] To more clearly illustrate the above-mentioned objectives, technical solutions, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0023] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, it will be readily apparent to those skilled in the art that the present invention may be implemented in other ways different from those described herein. Therefore, other possible implementations that can be obtained by those skilled in the art based on the embodiments described herein are all within the scope of protection of this application.

[0024] In this embodiment, terms such as "front," "back," "left," and "right" are used to indicate direction for clarity and do not necessarily indicate location or orientation. The positional relationships of various devices and mechanisms may differ in other specific embodiments.

[0025] The product processed in this embodiment of the invention is a flexible circuit board with a relatively long length. Both ends need to be processed and are centrally symmetrical. After the stamping device punches one end, it is rotated 180 degrees so that the other end is brought to the stamping device for further punching. The specific structure of this embodiment of the invention is described below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, the automatically reversible punch press 100 includes a housing and a frame 11. The housing has been removed for the purpose of showing the internal structure. A loading / unloading robot 20 is installed at the middle position on the top 111 of the frame 11, and the punching device 30 is installed on the left side of the middle 112 of the frame.

[0027] like Figure 3As shown, the stamping device 30 includes an upper die assembly 31 and a lower die assembly 32. The upper die assembly 31 can move up and down, and the lower die assembly 32 can move left and right along a sliding track 33 between the stamping position and the loading position. The lower die assembly 32 is shown in the loading position, where the loading / unloading robot 20 places the product to be stamped. A loading platform 12 for placing the product to be stamped is located at the rear of the stamping device 30, while a carrier receiving portion 13 for collecting the product carrier is located at the front of the stamping device 30, with its length parallel to the moving direction of the lower die assembly 32. The loading platform 12 can be configured to move between a product placement position and a product gripping position. The product placement position can be located outside the frame to facilitate placing the product to be stamped. Additionally, the loading platform 12 may include a vertical moving component, allowing the loading platform 12 to move vertically to adjust the height of the top product according to the stacking of products on it. The discharge conveyor track 14 for outputting punched finished products can be set on the right side of the punching device 30.

[0028] like Figure 4 and Figure 5 As shown, the loading / unloading robot 20 is mounted and fixed on the top 111 of the frame, supporting and fixing the Y-axis moving track 21 of the loading / unloading robot 20. Two Y-axis moving tracks 21 are provided, respectively supporting the two ends of the Y-axis moving module 22 and guiding it to move horizontally along the Y-axis direction. The rotating module 23 of the loading / unloading robot 20 is mounted below the Y-axis moving module 22, and an X-axis horizontal moving track 24 is provided on it. A first X-axis moving module 251 and a second X-axis moving module 252, which can move horizontally along the X-axis, are provided on the X-axis horizontal moving track 24. A first Z-axis moving module 261 is provided on the first X-axis moving module 251, and a second Z-axis moving module 262 is provided on the second X-axis moving module 252. A third Z-axis moving module 263 is also provided below the rotating module 23, and the third Z-axis moving module 263 is positioned between the first Z-axis moving module 261 and the second Z-axis moving module 262, serving as the first... The first suction cup 281, the second suction cup 282 (as a second gripping mechanism), and the third suction cup 283 (as a third gripping mechanism) are respectively mounted on the first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module 263. They can move relatively independently along the X-axis (the third gripping mechanism cannot move along the X-axis) and the Z-axis, and perform gripping and releasing actions independently. Each suction cup includes multiple suction nozzles with movable relative positions to accommodate products of different sizes. The first X-axis moving module 261 is equipped with a first positioning camera 271, and the second X-axis moving module 262 is equipped with a second positioning camera 272.

[0029] Since the X-axis moving track 24 is set on the rotating module 23, the direction of the X-axis can change as the rotating module rotates. In actual operation, except during the reversal rotation process, the X-axis direction remains perpendicular to the Y-axis direction, that is, parallel to the moving direction of the lower mold assembly 32. When the first X-axis moving module 251 and the second X-axis moving module 252 move in opposite directions to the two far ends of the X-axis horizontal moving track, the first X-axis moving module 251 and the second X-axis moving module 252 are in an extended state; when the first X-axis moving module 251 and the second X-axis moving module 252 move towards each other to near the third Z-axis moving module, the first X-axis moving module 251 and the second X-axis moving module 252 are in a retracted state.

[0030] The lower mold assembly 32 includes a lower mold and a mold platform 321 detachably connected to the lower mold, such as Figure 6 As shown, the mold platform 321 is provided with a cover plate 322 and a waste material receiving part 323. The cover plate 322 is provided with a handle 3221. When the cover plate 322 is pulled open, the waste material receiving part 323 can be exposed. After the punching process is completed and the lower die is removed from the mold platform, the cover plate can be pulled open by the handle 3221 to open the waste material receiving part 323 and remove the waste material contained therein.

[0031] The following describes the process flow for punching flexible circuit boards using an embodiment of this utility model. The product to be punched, placed on a carrier such as a separator, is placed on the loading platform 12 along with the carrier. Then, the loading platform 12 moves from the product placement position to the product gripping position. At this time, the first X-axis moving module 251 and the second X-axis moving module 252 are in an extended state. The loading and unloading robot 20 moves along the Y-axis to above the product to be punched. The first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module 263 move downwards. The first suction cup 281 and the second suction cup 282 respectively pick up the A and B ends of the product to be punched, and the third suction cup 283 picks up the middle part of the product that does not need to be processed. The first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module 263 move the product to be punched upwards to a certain position. The first X-axis moving module 251 and the second X-axis moving module 252 move inwards towards the middle of the X-axis moving track 24 to a retracted state. At the same time, the third Z-axis moving module 263 continues to rise, so that the product to be punched is stretched into a Z-shape to keep the ungrabbed part of the product to be punched flat. The Y-axis moving module 22 moves along the Y-axis to a position consistent with the front and back direction of the stamping device 30. At this time, the lower die assembly 32 of the stamping device is located at the loading position, and the first X-axis moving module 251 is located directly above the lower die assembly 32. The first positioning camera 271 accurately positions the A end of the product to be punched.

[0032] Then, the first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module descend synchronously until end A of the product to be punched is placed on the lower die assembly 32. After the first suction cup 281 releases the product to be punched, the first Z-axis moving module 261 drives the first suction cup 281 to move upward. The lower die assembly 32 moves end A of the product to be punched toward the punching position. At the same time, the third Z-axis moving module 263 moves the middle part of the product to be punched downward. The second X-axis moving module 262 drives end B of the product to be punched to move outward. The product to be punched is gradually flattened until the lower die assembly 32 moves to the punching position. The second suction cup 282 and the third suction cup 283 maintain the suction of the product to be punched.

[0033] The upper die assembly 31 of the stamping device 30 moves downward to punch the product to be punched. The punched waste enters the waste receiving part 323 through the lower die. After punching, the upper die assembly 31 moves upward, and the lower die assembly 32 moves from the punching position to the material feeding position. At the same time, the third Z-axis moving module 263 moves upward, and the second X-axis moving module 252 moves inward. The product is pulled back into a square shape. The first Z-axis moving module 261 moves downward, and the first suction cup 281 picks up the A end of the product again. The first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module 263 rise synchronously to a certain position. The rotating module 23 drives the X-axis moving track 24, each X-axis moving module, each Z-axis moving module, and the product to rotate 180 degrees. At this time, the second X-axis moving module 252 is located directly above the lower die assembly 32, and the second positioning camera 272 accurately positions the B end of the product.

[0034] Then, the first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module 263 descend synchronously until the B end of the product to be punched is placed on the lower die assembly 32. After the second suction cup 282 releases the product to be punched, the second Z-axis moving module 262 drives the second suction cup 282 to move upward. The lower die assembly 32 moves the B end of the product to be punched toward the punching position. At the same time, the third Z-axis moving module 263 moves the middle part of the product to be punched downward. The first X-axis moving module 251 drives the A end of the product to be punched to move outward. The product to be punched is gradually flattened until the lower die assembly 32 moves to the punching position. The first suction cup 281 and the third suction cup 283 maintain the suction of the product to be punched.

[0035] The upper die assembly 31 of the stamping device moves downward to punch the product to be punched. The punched waste enters the waste receiving part 323 through the lower die. After punching, the upper die assembly 31 moves upward and the lower die assembly 32 moves from the punching position to the material feeding position. At the same time, the third Z-axis moving module 263 moves upward and the first X-axis moving module 251 moves inward. The product is pulled back into a jig shape. The second Z-axis moving module 262 moves downward and the second suction cup 282 picks up the B end of the punched product again. The punching process of the product is completed.

[0036] The first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module 263 rise synchronously. The Y-axis moving module 22 moves to the receiving position. When the center of the discharge conveying track 14 is aligned with the center of the stamping device, the Y-axis moving module does not need to move. Then, the first Z-axis moving module 261, the second Z-axis moving module 262, and the third Z-axis moving module 263 descend synchronously until end A of the punched product is placed on the discharge conveying track 14. The first suction cup 281 releases the product. The third Z-axis moving module 263 descends until the middle of the punched product is also placed on the discharge conveying track 14. The third suction cup 283 releases the product. The second X-axis moving module 252 moves inward, and the second Z-axis moving module 262 moves downward until end B of the punched product is also placed on the conveying track 14. The second suction cup 282 releases the product, and the punched product is further conveyed outside the punch press.

[0037] Then the Y-axis moving module 22 moves above the loading platform 12. At this time, the first X-axis moving module 251 and the second X-axis moving module 252 are in an extended state. The three Z-axis moving modules descend to contact the carrier on which the product to be punched has been removed. After the three suction cups adsorb the carrier, the three Z-axis moving modules rise. The Y-axis moving module 22 drives the three Z-axis moving modules and the carrier to move above the carrier receiving part 13. After the three Z-axis moving modules descend and place the carrier, each suction cup detaches from the carrier and rises. Then, they move along the Y-axis to the product loading position to pick up the next product to be punched.

[0038] As can be seen from the above, during product punching, except for the punching end, the middle and other ends of the product are fixed by suction cups. Therefore, no displacement occurs during the punching process, resulting in precise product positioning and high processing accuracy. When reversing the product's orientation, each suction cup maintains its grip on the product, and the reversal operation does not cause any movement between the product and the suction cups, making product positioning easy. When the product's punching end is placed on the lower die assembly and moves with the lower die assembly, the third Z-axis moving module moves up and down accordingly, ensuring that the punching end does not move relative to the lower die assembly, thus guaranteeing processing accuracy.

[0039] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the scope of the invention. Any person skilled in the art may make modifications without departing from the scope of the invention; all variations or modifications made in accordance with the present invention shall be covered by the protection scope of the present invention.
