Description

Technical Field

[0001] The invention relates to the technical field of processing machinery, in particular to a material shaking mechanism which utilizes material shaking to realize the material breaking operation of easily-broken structural hardware. Background Art

[0002] In today's era of rapid technological development, electronic products are moving towards miniaturization and precision. In order to realize the diversified functions of electronic products, the small precision hardware designed plays a vital role. Although these precision hardware are small in size, they play a key role in the performance and stability of electronic products.

[0003] However, there are many thorny problems in the assembly and welding process of precision hardware. On the one hand, due to the small size and precise structure of precision hardware, it is extremely difficult to grasp and fix it, which brings severe challenges to automated assembly and welding. To solve this problem, a method of punching out an extension section when processing precision hardware is often used. Through this extension section, the precision hardware can be grasped and assembled or positioned to the corresponding position for welding more conveniently. After welding is completed, the extension section is disconnected.

[0004] On the other hand, the traditional method of disconnecting the extension section has obvious defects. In the past, a breakable wire was mainly set between the extension section and the precision hardware, and disconnection was achieved by pulling or breaking. However, this operation method will exert excessive tension on the precision hardware, causing a large degree of elastic deformation of the precision hardware, which is very likely to cause irreversible tensile deformation of the precision hardware, which will seriously affect its accuracy and increase the product defect rate.

[0005] In order to overcome the drawbacks of traditional pulling and breaking methods, a shaking method has been introduced on the market to disconnect the extension. This method uses the easy-to-break wire to automatically break under repeated force by swinging the extension back and forth, effectively avoiding excessive tension on precision hardware. However, during the working process, the shaking mechanism takes a certain amount of time to swing back and forth, resulting in its processing rate being significantly lower than the pulling or breaking method. In the modern manufacturing industry that pursues efficient production, this low processing rate has undoubtedly become a bottleneck restricting industrial development.

[0006] In summary, the existing precision hardware extension segment disconnection technologies all have their own shortcomings and cannot simultaneously meet the requirements of ensuring the precision of precision hardware and improving the processing rate. Therefore, developing a new extension segment disconnection technology that can effectively avoid damage to precision hardware and significantly improve processing efficiency has become a key issue that needs to be urgently solved in the current precision hardware processing field.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0023] See also Figure 1-5 In an embodiment of the present invention, a shaking material mechanism for realizing the breaking operation of easily-broken structural hardware by shaking material comprises a fixedly installed workpiece positioning unit 10, a first workpiece shaking material unit 20 and a second workpiece shaking material unit 30; the workpiece positioning unit 10 has a workpiece picking and placing area 101 and two workpiece processing areas 102 respectively located on both sides of the workpiece picking and placing area 101, the workpiece positioning unit 10 is provided with two movable workpiece positioning grooves 11 and a reciprocating power mechanism 12 for simultaneously driving the two workpiece positioning grooves 11 to move, wherein the two workpiece positioning grooves 11 correspond to the two workpiece processing areas 102 respectively, the reciprocating power mechanism 12 simultaneously drives the two workpiece positioning grooves 11 by reciprocating movement, so that the two workpiece positioning grooves 11 reciprocate between the workpiece picking and placing area 101 and the corresponding workpiece processing area 102, and the workpiece positioning unit 10 is also provided with two workpiece clamping mechanisms 13 respectively acting on the two workpiece processing areas 102, the workpiece clamping mechanism 13 is used to clamp the workpiece placed in the workpiece positioning groove 11; The first workpiece shaking machine group 20 and the second workpiece shaking machine group 30 act on two workpiece processing areas 102 respectively. The first workpiece shaking machine group 20 and the second workpiece shaking machine group 30 are both provided with a clamping mechanism 21 which can be raised and lowered, an eccentric wheel power mechanism 22 for driving the clamping mechanism 21 to move reciprocally up and down, and a waste trough 23 for receiving waste. The clamping mechanism 21 is used to clamp the workpiece on the workpiece processing area 102.

[0024] The working principle of the above technical solution is as follows: Initial placement: In the workpiece placement area 101 , the operator places the hardware with a fragile structure to be processed into one of the workpiece positioning grooves 11 . At this time, another workpiece positioning groove 11 is located in another workpiece processing area 102 .

[0025] First movement: The reciprocating power mechanism 12 is started, driving the workpiece positioning slot 11 with the hardware to move from the workpiece placement area 101 to the corresponding workpiece processing area 102. At the same time, another workpiece positioning slot 11 is synchronously moved from the workpiece processing area 102 to the workpiece placement area 101.

[0026] First processing: When the workpiece positioning groove 11 equipped with hardware reaches the workpiece processing area 102, the corresponding workpiece clamping mechanism 13 quickly acts to firmly clamp and fix the hardware in the workpiece positioning groove 11 to prevent displacement during the processing. Subsequently, the first workpiece shaking unit 20 set corresponding to the workpiece processing area 102 that has moved this time starts to work. The eccentric wheel power mechanism 22 operates, driving the clamping mechanism 21 to move back and forth. The clamping mechanism 21 descends and clamps the workpiece, and by continuously lifting and reciprocating, it simulates the shaking action, so that the fragile structure of the workpiece is gradually broken under repeated force.

[0027] Secondary placement and processing: while the hardware moved for the first time is being processed, a new hardware to be processed is placed in another workpiece positioning groove 11 just moved to the workpiece placement area 101 by a robot.

[0028] Transposition and circulation: When the hardware that is moved to the workpiece processing area 102 for the first time completes the material cutting operation, the reciprocating power mechanism 12 operates again to move the workpiece positioning groove 11 where the processed hardware is located from the workpiece processing area 102 back to the workpiece pick-up and placement area 101, and at the same time, the workpiece positioning groove 11 with the new hardware is moved from the workpiece pick-up and placement area 101 to another workpiece processing area 102. At this time, the robot can remove the processed workpiece and put the new hardware to be processed into the vacated workpiece positioning groove 11. The robot can use a PPU robot to achieve synchronous material picking and placing operations. Subsequently, the second workpiece shaking unit 30 corresponding to the workpiece processing area 102 that has moved this time begins to process the newly placed hardware, and this cycle is repeated to achieve continuous production.

[0029] The shaking mechanism proposed in the technical solution adopts a unique shaking and breaking method. The eccentric wheel power mechanism 22 drives the clamping mechanism 21 to reciprocate and rise and fall. During this process, the fragile structure of the workpiece is gradually broken under continuous and uniform force, which completely avoids the excessive pulling force applied instantly by the traditional method, and eliminates the irreversible tensile deformation of the workpiece caused by uneven force, thereby greatly improving the product quality and meeting the strict precision requirements of modern electronic products for precision components.

[0030] In terms of improving the processing speed, the shaking mechanism, through the two workpiece positioning grooves 11 and the two workpiece processing areas 102, cooperates with the reciprocating power mechanism 12, so that the two workpiece positioning grooves 11 can be moved alternately and efficiently between the workpiece picking and placing area 101 and the workpiece processing area 102. When one workpiece is being shaken and cut in the processing area, the other workpiece can be quickly loaded and unloaded in the picking and placing area, realizing continuous operation. When paired with the PPU manipulator, its synchronous picking and placing function further optimizes the entire workflow. The PPU manipulator can accurately and quickly complete the picking and placing actions in the workpiece picking and placing area 101, which is consistent with the processing rhythm of the shaking mechanism, reduces the idle time of the equipment, and can greatly improve the overall processing efficiency.

[0031] From the perspective of stability and reliability, the overall layout of the shaking mechanism is compact and reasonable, and the various components work together well, achieving a high degree of automation. The automated operation process reduces manual intervention and labor intensity, while avoiding processing errors and fluctuations caused by human factors. Each workpiece can be processed under the same stable conditions, ensuring a high degree of consistency in product quality.

[0032] In addition, the compact structure of the material shaking mechanism occupies a small area and can be arranged more flexibly in the production workshop, effectively improving the utilization rate of the production space.

[0033] To sum up, the shaking mechanism proposed in the technical solution fundamentally solves the problems of damaged precision and low processing rate when precision hardware is cut, and the layout of the structure can introduce a PPU manipulator to pick and place hardware, that is, when the hardware flows into the shaking mechanism from the previous station, a docking station for the flow of the previous station can be set in front of the workpiece positioning unit 10, and the PPU manipulator picks up and places the hardware from the docking station along the rear to the workpiece picking and placing area 101, and after the hardware processing is completed, it continues to move to the workpiece picking and placing area 101, and then the PPU manipulator moves the hardware in the workpiece picking and placing area 101 to the rear for unloading. The PPU manipulator is a manipulator based on a parallel mechanism. By connecting two heads for picking and placing hardware in parallel, it can simultaneously complete the entry operation of the processed hardware and the outflow operation of the processed hardware, providing an efficient, reliable and accurate new solution for the processing of precision hardware, and has broad market application prospects.

[0034] See also Figure 1-2On the basis of the above technical solution, it is further proposed that the workpiece positioning unit 10 also includes a first fixed seat 14 for fixed installation, a first linear guide 15 arranged horizontally on the first fixed seat 14, and a workpiece positioning plate 16 slidably connected to the first linear guide 15, the workpiece pick-up and placement area 101 and the workpiece processing area 102 are both arranged on the first fixed seat 14, the two workpiece positioning grooves 11 are both arranged on the workpiece positioning plate 16, the reciprocating power mechanism 12 is provided with a lateral push cylinder fixedly installed on the workpiece positioning plate 16, the lateral push cylinder is connected to the workpiece positioning plate 16 by power, and the workpiece clamping mechanism 13 includes a downward pressure cylinder 131 fixedly installed on the first fixed seat 14 and a downward pressure block 132 connected to the downward pressure cylinder 131 by power and corresponding to the workpiece processing area 102. The first fixed seat 14 provides a stable foundation for the entire workpiece positioning unit 10, ensuring that no displacement and shaking will occur during the processing process, thereby ensuring the processing accuracy. The sliding connection between the first linear guide 15 and the workpiece positioning plate 16 makes the movement of the workpiece positioning plate 16 more stable and accurate. The lateral push cylinder is directly fixed on the workpiece positioning plate 16 and is connected to the workpiece positioning plate 16 by power, and can quickly and powerfully push the workpiece positioning plate 16 to move on the first linear guide rail 15. When the pressing cylinder 131 is working, the pressing block 132 can quickly and accurately press the workpiece in the workpiece positioning groove 11. This design ensures that the workpiece always remains fixed during the material shaking and cutting process, avoiding the impact of the processing accuracy or the failure of the processing due to the shaking of the workpiece. Even in the case of high-speed shaking, the stability of the workpiece can be guaranteed, which is suitable for the processing of precision hardware of various shapes and materials.

[0035] See also Figure 1 and Figure 3On the basis of the above technical solution, it is further proposed that the first workpiece shaking material unit 20 and the second workpiece shaking material unit 30 further include a second fixed seat 24 for fixed installation, a second linear guide rail 25 vertically installed on the second fixed seat 24, and a connecting plate 26 slidably connected to the second linear guide rail 25, the clamping mechanism 21 is installed on the connecting plate 26, and the eccentric wheel power mechanism 22 is dynamically connected to the connecting plate 26. The clamping mechanism 21 includes a vertical plate 211 fixedly connected to the connecting plate 26, a clamping cylinder 212 installed on the vertical plate 211 and located directly above the second linear guide rail 25, and two clamping blocks 213 dynamically connected to the clamping cylinder 212 and cooperating with each other, the rear side of the workpiece positioning groove 11 is exposed to the rear side of the workpiece positioning plate 16, so as to expose the part of the workpiece to be disconnected from the rear side of the workpiece positioning groove 11 to be in a suspended state, and the two clamping blocks 213 are corresponding to the rear of the workpiece positioning groove 11 to clamp the part of the workpiece to be disconnected. The second fixed seat 24 provides a solid installation foundation for the entire unit, ensuring that no shaking or displacement occurs during operation, thereby improving the stability of the equipment. The second linear guide rail 25 installed vertically cooperates with the slidingly connected connecting plate 26, so that the clamping mechanism 21 can perform precise lifting and lowering movements along the guide rail. The vertical plate 211 firmly fixes the clamping cylinder 212 on the connecting plate 26. The clamping cylinder 212 is located directly above the second linear guide rail 25. The design is very clever, which not only facilitates power transmission, but also makes the entire clamping process more stable. The two mutually cooperating clamping blocks 213 can accurately clamp the part of the workpiece that needs to be disconnected under the drive of the clamping cylinder 212. This precise clamping operation can effectively avoid shaking or offsetting of the workpiece during the shaking process, thereby ensuring the accuracy and quality of the material cutting. The design of the exposed rear side of the workpiece positioning groove 11 makes the part of the workpiece that needs to be disconnected in a suspended state, which is convenient for the clamping block 213 to clamp from the rear. Such a design not only facilitates the clamping operation, but also avoids unnecessary damage to other parts of the workpiece during the clamping process. At the same time, the design of the suspended state enables the fragile structure of the workpiece to better withstand stress when shaking the material, which is conducive to the smooth disconnection of the extended section.

[0036] See also Figure 3On the basis of the above technical solution, it is further proposed that a longitudinal long hole 214 is provided at the lower part of the vertical plate 211, and a transverse long hole 215 is provided at the upper part of the vertical plate 211. The vertical plate 211 is connected to the connecting plate 26 by screws that can be adjusted longitudinally through the longitudinal long hole 214. The vertical plate 211 is connected to the clamping cylinder 212 by screws through the transverse long hole 215, so that the clamping cylinder 212 can be fine-tuned transversely along the transverse long hole 215. The design of the longitudinal long hole 214 and the transverse long hole 215 on the vertical plate 211 greatly enhances the adjustment flexibility of the equipment. Among them, the longitudinal long hole 214 enables the vertical plate 211 to be adjusted longitudinally on the connecting plate 26, and the longitudinal position of the clamping mechanism 21 can be flexibly adjusted according to the precision hardware of different sizes or types, so as to ensure that the clamping block 213 can accurately correspond to the part of the workpiece to be disconnected, thereby improving the accuracy of the clamping. The transverse long hole 215 allows the clamping cylinder 212 to be fine-tuned transversely, further optimizing the clamping position. When faced with some special workpieces that require extremely high clamping position accuracy, the operator can easily fine-tune the clamping cylinder 212 laterally to make the clamping block 213 accurately clamp the workpiece, avoiding problems such as loose clamping or damage to the workpiece due to position deviation, effectively improving the versatility and adaptability of the equipment to different workpieces.

[0037] See also Figure 3-4 , two clamping blocks 213 correspond to each other up and down, waste through holes 216 penetrating the upper and lower ends are provided on the two clamping blocks 213, waste troughs 23 are fixedly connected to the first fixing seat 14 or the second fixing seat 24, and waste troughs 23 correspond to the lower part of waste through holes 216, the front parts of the two clamping blocks 213 are used to clamp the part of the workpiece that needs to be disconnected, and after clamping the part of the workpiece that needs to be disconnected, the part of the workpiece that needs to be disconnected occupies a larger vertical projection area corresponding to the waste through holes 216, and the front position corresponding to the clamping block 213 located below has a guide slope 217 inclined along the waste through holes 216, so as to guide the part of the workpiece that needs to be disconnected to fall along the waste through holes 216. During the shaking process, when the extended section of the workpiece is disconnected, the waste can directly fall to the waste trough 23 below through the waste through holes 216. This design avoids the accumulation of waste around the clamping block 213, reduces the interference of waste on the clamping operation and the shaking process, and ensures the continuous and stable operation of the equipment. At the same time, the guide slope 217 located on the lower clamping block 213 can guide the disconnected waste to fall more smoothly along the waste through hole 216, prevent the waste from being stuck in the through hole, and improve the efficiency of waste cleaning. The layout design of the waste trough 23 corresponding to the bottom of the waste through hole 216 makes the waste collection more orderly. Whether it is fixedly connected to the first fixed seat 14 or the second fixed seat 24, it can ensure that the waste falls accurately into the waste trough 23, which is convenient for centralized processing. This not only keeps the processing area clean and tidy, reduces the workload of manual waste cleaning, but also reduces the risk of equipment failure caused by waste residue, and extends the service life of the equipment.

[0038] See also Figure 5 On the basis of the above technical solution, it is further proposed that the eccentric wheel power mechanism 22 includes a motor 221 fixedly mounted on the second fixed seat 24, a rotating block 222 that is dynamically connected to the motor 221, an eccentric shaft 223 that is arranged on the rotating block 222 and deviates from the rotating axis of the motor 221, and a transmission block 224 that is mounted on the lower end of the connecting plate 26, and a movable groove 225 with a height corresponding to the radial direction of the eccentric shaft 223 is transversely opened on the transmission block 224, and the eccentric shaft 223 is movably docked with the movable groove 225. The motor 221 drives the rotating block 222 to rotate, and the eccentric shaft 223 on the rotating block 222 that deviates from the rotating axis of the motor 221 is movably docked with the movable groove 225 on the transmission block 224. This structure can smoothly and efficiently convert the circular motion of the motor 221 into the reciprocating lifting motion of the connecting plate 26. In this way, the clamping mechanism 21 can achieve a stable material shaking action, ensuring that the easily breakable structure of the workpiece is broken under uniform force, avoiding the problem of poor material breaking effect or additional damage to the workpiece caused by unstable power transmission. Compared with the traditional power transmission method, the design of the eccentric wheel power mechanism 22 is more concise and reliable, reducing the intermediate transmission links, reducing energy loss and the probability of failure, and improving the overall operation efficiency and stability of the equipment.

[0039] In addition, an adjustment slot 226 is provided at the end of the rotating block 222, and an adjustment block 227 that can be slidably adjusted along the adjustment slot 226 is tightly connected to the adjustment slot 226 by screws, and the eccentric shaft 223 is fixed on the adjustment block 227. The design of the adjustment slot 226 and the adjustment block 227 brings high flexibility and adjustability to the material shaking mechanism. Since the eccentric shaft 223 is fixed on the adjustment block 227 that can be slidably adjusted along the adjustment slot 226, the operator can change the distance between the eccentric shaft 223 and the rotating axis of the motor 221, that is, change the eccentricity, by adjusting the position of the adjustment block 227 in the adjustment slot 226 according to the characteristics and processing requirements of different workpieces. The change of the eccentricity will directly affect the lifting stroke and speed of the connecting plate 26, and then adjust the amplitude and frequency of the shaking material. For some fragile workpieces, the eccentricity can be appropriately reduced, the force and frequency of shaking can be reduced to avoid damage to the workpiece due to excessive force; while for fragile structures that are difficult to break, the eccentricity can be increased, the force and frequency of shaking can be increased to ensure that the breaking operation can be completed smoothly. This adjustable design allows the shaking mechanism to adapt to the processing needs of various types and specifications of precision hardware, greatly improving the versatility and applicability of the equipment.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
