Description

Technical Field

[0001] The invention relates to the technical field of punching equipment, in particular to a punching and forming device and a forming method for notebook computer components. Background Art

[0002] With the development of science and technology, various electronic products have emerged, bringing great changes to people's lives. In particular, the use of computers has changed people's lifestyles and accelerated their pace of life. In recent decades, with the development of material science and the emergence of smaller integrated chips, computers have evolved from large desktop computers to small, thin, light and easy-to-carry laptops.

[0003] A laptop is a type of portable computer. Most of the laptops we see are handheld computers. A laptop is mainly composed of a screen, a motherboard, a keyboard and other components. The keyboard on a laptop is usually installed on the laptop shell through a keyboard frame to facilitate typing on the laptop.

[0004] As is known, the structure of the notebook keyboard frame is relatively simple, and is generally formed by high-precision punching equipment. The punching device of the keyboard frame in the prior art, such as the Chinese patent with application number 202120052760.6, authorization announcement number CN221515774U, and name of a notebook keyboard frame punching device, discloses a notebook keyboard frame punching device, including a punching seat, a hydraulic rod and a punching knife, a punching opening is opened on the top of the punching seat, and a side frame is fixed on the side of the punching seat, a hydraulic rod is fixed in the middle of the upper part of the side frame, and a movable plate is fixed at the output end of the hydraulic rod, and a punching knife is fixed in the middle of the lower part of the movable plate, positioning rods are fixed at both ends of the inner side of the side frame, a discharge block is arranged inside the punching knife, and positioning components are fixed at both ends of the movable plate, a discharge component is installed at the inner bottom end of the punching seat, and a feeding component is fixed on one side of the punching seat. In the above patent, when the punching knife is driven downward by the movable plate, the positioning component is driven to automatically fix the plate below, and the feeding component is used to improve the processing efficiency of the device.

[0005] Another example is the Chinese patent with application number 202320681297.7, authorization announcement number CN219188311U, and name of a mobile phone frame punching device. The above patent discloses a mobile phone frame punching device, including a base, on which a cylinder is fixedly mounted, the telescopic end of the cylinder is slidably connected to the base, and the telescopic end of the cylinder is fixedly connected to an upper mold body. In the above patent, the mobile phone frame accessories can be punched by setting the cylinder, upper mold body, lower mold body and other structures. Under the action of the guide plate, the upper mold body can be guided, which is convenient for operators to quickly dismantle and replace the lower mold body, avoiding the problem of disassembly and assembly using bolts and knobs in the prior art, which is inconvenient to use.

[0006] In the prior art, such as the above-mentioned patent, the efficiency of punching the sheet can be improved to a certain extent. It is known that before the keyboard frame is punched and formed, the keyboard frame sheet used for punching and forming is first punched from the predetermined raw material to facilitate the storage and transportation of the keyboard frame sheet. Since the size of the equipment for punching the keyboard frame is fixed, it is also necessary to punch the raw materials with wider sizes to meet the punching needs of the subsequent keyboard frame. However, in the prior art, when producing keyboard frame sheets, it is necessary to use a transmission device to transmit them to the punching station during the punching process, and the punching knife is driven by a driving member to slide downward to punch the sheet. When the punching knife is punching the sheet, the transmission device must stop working. After the punching is completed, the transmission device restarts to transfer the sheet. This method requires the setting of a complex program to control the coordination of the transmission device and the punching knife, and the long-term startup and closing of the transmission device will lead to an increase in the failure rate of the transmission device. At the same time, when the punching knife is punching the plate downward, in order to improve the stability of the plate during the punching operation, the prior art usually needs to set a fastening mechanism to fix the plate. After the punching operation is completed, the plate needs to be actively unlocked before subsequent operations can be performed, which increases the workload.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-10The present invention provides a technical solution: a notebook computer component punching and forming device, comprising a frame 1 and a mounting frame 2 mounted on the frame 1, a punching knife 5 is slidably connected to the mounting frame 2, a punching station is arranged on the frame 1 directly below the punching knife 5, a plate workpiece 3 is mounted on the frame 1, and a shift feeding mechanism is arranged on the frame 1, and the shift feeding mechanism intermittently drives the plate workpiece 3 to move; a servo cylinder 4 for driving the punching knife 5 to slide downward is arranged on the mounting frame 2, and the punching knife 5 is connected to the shift feeding mechanism through a driving mechanism 7; and the mounting frame 2 is also provided with There is a fastening mechanism 8, which intermittently abuts against the sheet workpiece 3; during operation, when the servo cylinder 4 drives the punching knife 5 to move downward, the linkage mechanism 9 drives the fastening mechanism 8 to fix the sheet workpiece 3, and the driving mechanism 7 drives the mobile feeding mechanism to unlock and reset the sheet workpiece 3; when the servo cylinder 4 drives the punching knife 5 to move upward, the driving mechanism 7 and the linkage mechanism 9 drive the fastening mechanism 8 to unlock the sheet workpiece 3, and the driving mechanism 7 also drives the mobile feeding mechanism to clamp the sheet workpiece 3 and then drives the sheet workpiece 3 to slide to one side of the punching station.

[0026] Specifically, the punching and forming device for notebook computer components includes a frame 1 and a mounting frame 2 installed on the frame 1. Specifically, a plurality of support members are arranged on the bottom of the frame 1, each support member includes a support leg fixedly connected to the bottom of the frame 1, and an anti-skid pad is arranged on the bottom of the support leg to improve the stability of the punching and forming device during operation. A controller 16 for controlling the operation of the entire device is arranged on the frame 1. The controller 16 is a PLC controller 16, which is a prior art, and the structure and working principle are not described in detail here. Specifically, a punching knife 5 is slidably connected to the mounting frame 2, wherein the punching knife 5 specifically includes a bearing plate and a tool unit installed on the bottom of the bearing plate. The installation method of the tool unit is set according to the needs of the working environment, and can ensure that the punching is completed in one time. At the same time, a punching station is arranged on the frame 1 directly below the punching knife 5, and a plate workpiece 3 is installed on the frame 1. When the punching knife 5 slides downward, the plate workpiece 3 located at the punching station is punched.

[0027] A shifting loading mechanism is provided on the frame 1, and the shifting loading mechanism intermittently drives the plate workpiece 3 to move, so as to drive the plate workpiece 3 to be loaded. The intermittent driving of the plate workpiece 3 to move means that there are two working states between the shifting loading mechanism and the plate workpiece 3 during the working process: first, when loading, the shifting loading mechanism fixes the workpiece for loading; second, when the shifting loading mechanism is reset, it will not drive the plate workpiece 3 to slide in the opposite direction, so the plate workpiece 3 that has been loaded will not be unloaded, thereby meeting the working needs.

[0028] The mounting frame 2 is provided with a servo cylinder 4 for driving the punching knife 5 to slide downward, providing power for the punching knife 5 to slide downward. The punching knife 5 is connected to the shifting feeding mechanism through a driving mechanism 7, so as to provide power for the movement of the mobile feeding mechanism, eliminating the need for manual feeding by workers, greatly improving the working efficiency of the punching and forming device, and eliminating the need for a separate driving source to drive the shifting feeding mechanism to move, thus saving energy and cost to a certain extent.

[0029] In addition, a fastening mechanism 8 is also provided on the mounting frame 2, and the fastening mechanism 8 intermittently abuts against the plate workpiece 3, that is, when the fastening mechanism 8 abuts against the plate workpiece 3, the stability of the plate workpiece 3 during the punching operation can be improved, and the plate workpiece 3 can be avoided from being offset during the punching operation, thereby improving the punching quality of the plate workpiece 3 and meeting the work needs; when the punching operation is completed, the shifting feeding mechanism drives the fastening mechanism 8 to separate from the plate workpiece 3, which is convenient for unloading the plate workpiece 3 after punching, reduces the influence of the fastening mechanism 8 on the unloading of the plate workpiece 3, further improves the practicability of the punching and forming device, and has a better use effect.

[0030] Specifically, the servo cylinder 4 drives the punching knife 5 to slide downward to perform the punching operation and reset upward to facilitate the next punching operation. The above operation process will generate two workstations respectively.

[0031] First, when the servo cylinder 4 drives the punching knife 5 to move downward, the linkage mechanism 9 drives the fastening mechanism 8 to fix the sheet workpiece 3; that is, during use, when the fastening mechanism 8 abuts against the sheet workpiece 3, it can improve the stability of the sheet workpiece 3 during the punching operation, avoid the offset of the sheet workpiece 3 during the punching operation, thereby improving the punching quality of the sheet workpiece 3 and meeting the work needs. At the same time, in this process, the fastening mechanism 8 fixes the sheet workpiece 3 in a completely passive manner, which is simple and convenient to operate, greatly facilitates later inspection and maintenance, and has a better use effect. During the downward movement of the punching knife 5, the driving mechanism 7 will drive the shifting feeding mechanism to unlock the sheet workpiece 3 and slide in the opposite direction, so that the shifting feeding mechanism is reset, which is convenient for the next feeding operation and greatly improves the use effect.

[0032] Second, when the servo cylinder 4 drives the punching knife 5 to move upward, the driving mechanism 7 and the linkage mechanism 9 drive the fastening mechanism 8 to unlock the sheet workpiece 3. The driving mechanism 7 also drives the mobile feeding mechanism to clamp the sheet workpiece 3 and then drives the sheet workpiece 3 to slide toward the punching station. That is, after the punching and forming operation is completed, the shift feeding mechanism drives the fastening mechanism 8 to separate from the sheet workpiece 3, which is convenient for the unloading of the sheet workpiece 3 after punching and reduces the influence of the fastening mechanism 8 on the unloading of the sheet workpiece 3. In this stroke, the driving mechanism 7 drives the shift feeding mechanism to fix the sheet workpiece 3 and then drives the subsequent sheet workpiece 3 to slide toward the punching station again, realizing the automatic loading of the sheet workpiece 3. In this process, there is no need for workers to manually load the material, which greatly improves the working efficiency of the punching and forming device. There is no need to set up a separate driving source to drive the shift feeding mechanism to move, which saves energy and cost to a certain extent.

[0033] In the embodiment provided by the present invention, the shifting feeding mechanism includes a clamping member 6 slidably connected to the mounting frame 2; wherein the clamping member 6 includes a clamping frame 6.1, the clamping frame 6.1 is in a "U" shape, and a clamping plate 6.2 is vertically slidably connected inside the clamping frame 6.1, and a plurality of groups of connecting springs 6.4 are arranged between the clamping plate 6.2 and the clamping frame 6.1; a guide rod 6.3 is fixedly connected to the clamping plate 6.2, and an avoidance groove is arranged on the side wall of the clamping frame 6.1, and the guide rod 6.3 slides vertically with the clamping frame 6.1 through the avoidance groove. A guide portion 10 is arranged between the guide rod 6.3 and the mounting frame 2, and the guide portion 10 includes a guide groove opened on the mounting frame 2, and the guide rod 6.3 moves inside the guide groove. Specifically, the guide groove includes a first station 10.1, a second station 10.2, a third station 10.3, and a fourth station 10.4, wherein the guide rod 6.3 slides inside the first station 10.1, the second station 10.2, the third station 10.3, and the fourth station 10.4.

[0034] Specifically, refer to Fig.10 In actual use, when the shifting feeding mechanism drives the plate workpiece 3 to feed, the guide rod 6.3 at this moment slides inside the first station 10.1, that is, the guide rod 6.3 drives the clamping plate 6.2 to abut against the plate workpiece 3 to fix the plate workpiece 3 (in this stroke, the connecting spring 6.4 is in a stretched state, that is, the connecting spring 6.4 has a certain elasticity). When the clamping frame 6.1 slides, it will drive the plate workpiece 3 to slide together; When the sheet workpiece 3 slides to the punching station, the guide rod 6.3 slides from the first station 10.1 to the second station 10.2. At this moment, the connecting spring 6.4 pulls the guide rod 6.3 upward in the process of restoring elastic deformation. At this moment, the guide rod 6.3 is located at the end of the second station 10.2; When the shifting feeding mechanism is reset, that is, when the clamping frame 6.1 slides in the reverse direction, the guide rod 6.3 at this moment will slide from the second station 10.2 to the third station 10.3. Since the second station 10.2 and the third station 10.3 are inclined, when the guide rod 6.3 slides from the second station 10.2 to the third station 10.3, the clamping plate 6.2 will slide upward. At this moment, the clamping plate 6.2 will not abut against the sheet workpiece 3, that is, when the clamping frame 6.1 slides in the reverse direction, the sheet workpiece 3 that has been loaded will not be unloaded. At the same time, when the guide rod 6.3 slides from the second station 10.2 to the third station 10.3, the connecting spring 6.4 will be in a compressed state, and the connecting spring 6.4 will still have a certain elasticity; When the guide rod 6.3 slides from the third station 10.3 to the fourth station 10.4, the connecting spring 6.4 at this moment restores its elastic deformation and drives the guide rod 6.3 to slide downward, so that the clamping plate 6.2 can continue to slide downward and abut against the plate workpiece 3 through the guide rod 6.3; When the shift feeding mechanism is loading, the guide rod 6.3 will slide from the fourth station 10.4 to the first station 10.1 at this moment. Since the connection between the fourth station 10.4 and the first station 10.1 is in a wedge shape, when the guide rod 6.3 slides from the fourth station 10.4 to the first station 10.1, it will continue to drive the clamping plate 6.2 to slide downward and continuously abut against the sheet workpiece 3, thereby increasing the friction between the clamping plate 6.2 and the sheet workpiece 3, fixing the sheet workpiece 3, and when the clamping frame 6.1 slides, the loading operation of the sheet workpiece 3 can be realized, and the use effect is better.

[0035] The above working process is repeated in a cycle to realize the automatic loading operation of the plate workpiece 3.

[0036] In the embodiment provided by the present invention, the driving mechanism 7 includes an annular plate 7.1 rotatably connected to the mounting frame 2, and the annular plate 7.1 is rotatably connected to the mounting frame 2 through a positioning rod to meet the working requirements. A spur gear 7.6 is installed on the positioning rod, and the punching knife 5 is provided with a bidirectional rack 7.2 through a connecting block, and one side of the bidirectional rack 7.2 is meshed with the spur gear 7.6; a fixing rod 7.3 is fixedly connected to the annular plate 7.1, and a driving ring 7.4 is sleeved on the fixing rod 7.3, and the fixing rod 7.3 slides inside the driving ring 7.4, and the driving ring 7.4 is fixedly connected to the clamping frame 6.1 through a fastening rod 7.5. Therefore, when the servo cylinder 4 drives the punching knife 5 to slide downward, the bidirectional rack 7.2 will drive the spur gear 7.6 to rotate, and then the ring plate 7.1 can be driven to rotate through the cooperation between the spur gear 7.6 and the positioning rod. During the rotation of the ring plate 7.1, the fixing rod 7.3 slides inside the driving ring 7.4, and the driving ring 7.4 and the fastening rod 7.5 drive the clamping frame 6.1 to slide, so that the clamping frame 6.1 can be driven to slide to the side away from the punching station, so as to realize the reset of the clamping frame 6.1. When the annular plate 7.1 slides upward, the bidirectional rack 7.2 drives the spur gear 7.6 to rotate in the opposite direction, and then the cooperation between the spur gear 7.6 and the positioning rod can drive the annular plate 7.1 to rotate. During the rotation of the annular plate 7.1, the fixing rod 7.3 slides inside the driving ring 7.4, and the cooperation between the driving ring 7.4 and the fastening rod 7.5 drives the clamping frame 6.1 to slide, so that the clamping frame 6.1 can be driven to slide toward the side close to the punching station. The loading operation of the plate workpiece 3 is realized through the cooperation between the clamping parts 6, etc., which is simple and convenient to operate and meets the working needs.

[0037] In the embodiment provided by the present invention, the fastening mechanism 8 includes a positioning frame 8.1 slidably connected to the mounting frame 2, and a clamping plate 8.3 is slidably connected to the positioning frame 8.1. Specifically, a plurality of limit rods 8.2 are fixedly connected to the clamping plate 8.3, and each limit rod 8.2 is slidably connected to the positioning frame 8.1 through a corresponding positioning groove, so as to improve the stability of the clamping plate 8.3 when sliding. More specifically, a pressure spring 8.4 is arranged between the limit rod 8.2 and the positioning groove, and the elastic force of the pressure spring 8.4 drives the clamping plate 8.3 to abut against the sheet workpiece 3. The linkage mechanism 9 drives the positioning frame 8.1 to slide toward the sheet workpiece 3 to fix the sheet workpiece 3. A reset spring 8.5 is also arranged between the clamping plate 8.3 and the mounting frame 2, and the elastic force of the reset spring 8.5 drives the positioning frame 8.1 away from the sheet workpiece 3. A wedge-shaped driving groove is provided on the positioning frame 8.1, and the linkage mechanism 9 includes a linkage gear 9.3 rotatably connected to the mounting frame 2, a gear ring 9.4 is fixedly connected to the outer side of the annular plate 7.1, and the gear ring 9.4 is meshed with the linkage gear 9.3; a linkage rack 9.2 is vertically slidably connected to the mounting frame 2, and a wedge-shaped driving block 9.1 is fixedly connected to the bottom of the linkage rack 9.2, and the linkage rack 9.2 is meshed with the other side of the linkage gear 9.3. Specifically, when the servo cylinder 4 drives the punching knife 5 to slide downward, the bidirectional rack 7.2 drives the spur gear 7.6 to rotate, and then the cooperation between the spur gear 7.6 and the positioning rod drives the annular plate 7.1 to rotate. The rotation of the annular plate 7.1 drives the clamping frame 6.1 to slide away from the punching station. The gear ring 9.4 is also driven to rotate, and then the linkage rack 9.3 drives the linkage rack 9.2 to slide downward, and the cooperation between the wedge drive block 9.1 and the wedge drive groove drives the positioning frame 8.1 to slide horizontally. The positioning frame 8.1 drives the clamping plate 8.3 to fix the sheet workpiece 3 to meet the working needs. When the servo cylinder 4 drives the punching knife 5 to slide upward, the linkage mechanism 9 drives the wedge drive block 9.1 to slide upward, and the positioning frame 8.1 loses pressure at this moment. At this moment, the reset spring 8.5 restores the elastic deformation and drives the clamping frame 6.1 to slide away from the sheet workpiece 3, unlocking the sheet workpiece 3, which is convenient for the subsequent unloading of the sheet workpiece 3 after punching.

[0038] In the embodiment provided by the present invention, a conveying mechanism for conveying the punched workpiece is also provided at the bottom of the frame 1, so as to further improve the practicality of the punching and forming device. The conveying mechanism includes a conveying frame 11 connected to the frame 1, and a plurality of conveying rollers 13 are rotatably connected to the conveying frame 11, and a conveyor belt 12 is sleeved between the plurality of conveying rollers 13, wherein the conveying rollers 13 and the conveyor belt 12 are prior art, and can realize that when the conveying rollers 13 rotate, the conveyor belt 12 rotates to convey the workpiece to a predetermined position. The driving mechanism 7 is connected to one of the conveying rollers 13 through an intermittent connection mechanism 14, so as to further improve the practicality of the punching and forming device, and achieve a better use effect. When the servo cylinder 4 drives the punching knife 5 to move upward, the driving mechanism 7 drives the intermittent connection mechanism 14 to drive the conveying roller 13 to rotate, and the workpiece after punching is conveyed to a predetermined position through the conveyor belt 12, so as to realize the unloading of the workpiece, so as to greatly improve the practicality of the punching and forming device.

[0039] In the embodiment provided by the present invention, the intermittent connection mechanism 14 includes a connecting rod 14.2 rotatably connected to the conveying frame 11, and a transmission gear 14.1 is installed on the connecting rod 14.2, and the transmission gear 14.1 is meshed with the side of the bidirectional rack 7.2 away from the spur gear 7.6; one of the conveying rollers 13 is fixedly connected to a mounting cylinder 15.1, and an intermittent connection unit 15 is arranged on the mounting cylinder 15.1, and the connecting rod 14.2 drives the intermittent connection unit 15 to move through a bevel gear transmission part. Specifically, the bevel gear transmission part includes a first bevel gear 14.3 installed on the connecting rod 14.2 and a second bevel gear 14.4 arranged on the mounting cylinder 15.1, and the first bevel gear 14.3 is meshed with the second bevel gear 14.4. When the servo cylinder 4 drives the punching knife 5 to move upward, the transmission gear 14.1 will be driven to rotate through the bidirectional rack 7.2, and then the connecting rod 14.2 will be driven to rotate. When the connecting rod 14.2 rotates, the first bevel gear 14.3 and the second bevel gear 14.4 will drive the installation cylinder 15.1 to rotate. When the installation cylinder 15.1 rotates, the intermittent connection unit 15 drives the conveying roller 13 to rotate, and the workpiece is conveyed. Therefore, the power of the servo cylinder 4 can be fully utilized, and there is still no need to set up a separate driving source to drive the conveying mechanism to move, which further achieves the effect of cost saving. At the same time, the intermittent conveying of the workpiece will not cause excessive consumption of energy, and is suitable for wide promotion and use.

[0040] In the embodiment provided by the present invention, the intermittent connection unit 15 includes a driving rod 15.2, and a plurality of bases are fixedly connected to the driving rod 15.2, and each base is rotatably connected to a ratchet 15.3. Specifically, a limiting portion is provided between the ratchet 15.3 and the base, and the limiting portion allows the ratchet 15.3 and the base to only rotate clockwise to a certain degree, and cannot rotate counterclockwise. A torque spring is provided between each ratchet 15.3 and the corresponding base, and a tooth groove 15.4 is provided on the mounting cylinder 15.1, and the elastic force of the torque spring drives the ratchet 15.3 to be clamped in the tooth groove 15.4. During use, when the servo cylinder 4 drives the punching knife 5 to move upward, it will drive the transmission gear 14.1 to rotate through the bidirectional rack 7.2, and then drive the connecting rod 14.2 to rotate. When the connecting rod 14.2 rotates, the cooperation between the first bevel gear 14.3 and the second bevel gear 14.4 drives the mounting cylinder 15.1 to rotate. Specifically, at this moment, the mounting cylinder 15.1 rotates counterclockwise. During the rotation stroke of the mounting cylinder 15.1, the driving rod 15.2 is driven to rotate through the cooperation between the tooth groove 15.4 and the ratchet 15.3. When the driving rod 15.2 rotates, it drives a conveying roller 13 connected to the driving rod 15.2 to rotate, and then the conveyor belt 12 can be driven to rotate through multiple groups of conveying rollers 13 to transport the workpiece, and the use effect is better. At the same time, when the punching knife 5 slides downward, the mounting cylinder 15.1 will rotate clockwise at this moment. At this time, the tooth groove 15.4 of the mounting cylinder 15.1 will abut against the back of the ratchet 15.3 when the mounting cylinder 15.1 rotates. At this moment, the ratchet 15.3 will also flip clockwise when the mounting cylinder 15.1 rotates. Therefore, it cannot drive the driving rod 15.2 to rotate, and then will not drive the conveying roller 13 to rotate, so it will not drive the workpiece to slide in the reverse direction, meeting the working needs.
