Description

Technical Field

[0001] This invention relates to the field of automated processing technology, and in particular to a punching and edge-removing device. Background Technology

[0002] When injection molding plastic products, smaller products are typically injected onto a carrier. After molding, they need to be punched off the carrier. During injection, sprue residue is left at the gate, which must be removed after molding, leaving only the finished product. Smaller products are not only difficult to punch, but also difficult to remove sprue residue. For example, small, thin sheets are prone to sticking together during punching. Therefore, many still require manual punching and sprue removal, which is inefficient and significantly impacts production efficiency.

[0003] The punched products are usually dropped directly for collection. When subsequent burr removal and size inspection are required, the product separation and positioning are very difficult, which brings inconvenience to the subsequent product inspection. Summary of the Invention

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0061] In this embodiment of the invention, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly. The terms "first," "second," etc., used in this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0062] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0063] The punching and trimming device of the present invention is used for punching and trimming sheet-shaped workpieces. The sheet-shaped workpiece 100 is a thin sheet product with small size and thickness, which can be an injection molded part or a metal sheet. In one embodiment, the sheet-shaped workpiece 100 is a plastic sealing ring. The shape of the sheet-shaped workpiece 100 in this application is shown in [reference needed]. Figures 1 to 4 , Figure 1 This is a schematic diagram of a sheet-like workpiece after injection molding (model 100). Figures 2 to 4 This is a schematic diagram of the sheet-like workpiece 100. The sheet-like workpiece 100 is injection molded, with an overall frustum shape and a hollow interior. A rectangular hole 101 is formed at the top of the frustum, serving as a seal for the atomizing inhaler. During injection molding, due to the mold design, 16 sheet-like workpieces 100 can be formed simultaneously, and these 16 workpieces 100 are evenly distributed circumferentially. The outer periphery of the sheet-like workpiece 100 forms its carrier 200, which is actually the sprue residue generated during injection molding. Due to its structural characteristics, plastic residue also remains in the rectangular hole 101 of the sheet-like workpiece 100 after injection molding. Therefore, after injection molding, the sheet-like workpiece 100 of this application requires a process to remove the sprue residue and a process to separate the sheet-like workpiece 100 from the surrounding carrier 200 by punching and edge-removing, thereby removing the plastic sprue residue on and around the sheet-like workpiece 100 to obtain the sheet-like workpiece 100 product.

[0064] Please see Figures 5 to 20 , Figure 5 This is a top view of the punching and edge-removing device of the present invention. The punching and edge-removing device includes a feeding assembly 1, a punching assembly 2, and a receiving assembly 3. The feeding assembly 1 is used to place and support the sheet-like workpiece 100 with remaining material and the carrier 200, conveying the sheet-like workpiece 100 to below the punching assembly 2. The punching assembly 2 is used to perform the punching and edge-removing process, separating the sheet-like workpiece 100 from the carrier 200. The receiving assembly 3 is used to receive material below the punching assembly 2 during punching, that is, to receive the punched sheet-like workpiece 100. After edge removal, the sheet-like workpiece 100 falls under gravity, directly landing on the receiving assembly 3, eliminating the risk of adhesion and deformation caused by free fall.

[0065] The feeding assembly 1 includes a power mechanism 11 and a feeding fixture 12. The feeding fixture 12 is used to place the sheet-like workpiece 100 and the carrier 200 that supports the sheet-like workpiece 100. For the specific structure, please refer to [reference needed]. Figure 8 The loading fixture 12 is circular in shape and has multiple through holes arranged in a circular pattern. The number and arrangement of the through holes correspond to the number and arrangement of the sheet workpieces 100. After the carrier 200 and the sheet workpieces 100 are placed on the loading fixture 12, the sheet workpieces 100 correspond one-to-one with the through holes. After being punched and de-edged by the punching assembly 2, the sheet workpieces 100 fall out of the through holes. The power mechanism 11 is used to drive the loading fixture 12 to translate. The punching assembly 2 and the receiving assembly 3 are located on the path of the translation of the loading fixture 12. Specifically, the punching assembly 2 and the receiving assembly 3 are located above and below the path of the translation of the loading fixture 12, respectively.

[0066] The punching assembly 2 includes a telescopic mechanism 21 and a first punch 22. The telescopic mechanism 21 can drive the first punch 22 to rise and fall. The first punch 22 has a hollow interior forming a punch hole, which is used to punch the edge of the sheet-like workpiece 100. The inner diameter of the punch hole is the same as the outer diameter of the sheet-like workpiece 100. The punching process separates the sheet-like workpiece 100 from the carrier 200. To adapt to actual production, the number of first punches 22 in this application is also 16, and they are evenly distributed in a circumferential shape, which is the same as the distribution of the sheet-like workpieces 100 on the carrier 200. 16 sheet-like workpieces 100 can be punched at one time, resulting in high production efficiency.

[0067] The receiving assembly 3 includes a receiving fixture 31 and a lifting assembly 32. The receiving fixture 31 is located below the first punch 22, and its top is provided with a receiving platform 311 for supporting the sheet-like workpiece 100. The lifting assembly 32 is used to lift and lower the receiving fixture 31, allowing it to rise to contact the bottom of the sheet-like workpiece 100. Before the punching assembly 2 punches the sheet-like workpiece 100, the lifting assembly 32 lifts the receiving fixture 31, causing the receiving platform 311 to contact the bottom of the sheet-like workpiece 100, serving as a lower receiving device. Afterward, the punching assembly 2 presses down, and the first punch 22 punches the sheet-like workpiece 100, which falls directly onto the receiving fixture 31 below.

[0068] With the above settings, during the punching process, the lifting component 32 synchronously drives the receiving fixture 31 to lift it to a specific height, so that the sheet workpiece 100 after edge removal falls directly onto the receiving surface formed by the receiving fixture 31. By dynamically matching the height, the risk of adhesion and deformation caused by the free fall of the product is eliminated, and the problem of coordinated control of adhesion and positioning accuracy during punching of thin sheet products is solved.

[0069] Please see Figures 9 to 11 In this application, the telescopic mechanism 21 includes a power source 211, an upper base 212, a punch mounting part 213 and a lower base 214. Specifically, the power source 211 drives the upper base 212 and the punch mounting part 213 to move downward in the vertical direction.

[0070] The punch mounting part 213 is fixedly connected to the upper base 212.

[0071] Both the upper base 212 and the lower base 214 are disc-shaped, arranged opposite each other with a certain space between them. Each base 212 and the lower base 214 has a corresponding first punch through-hole, through which the first punch 22 passes, and the diameter of the first punch 22 is slightly larger than its outer diameter. The number and distribution of the first punch through-holes match the first punch 22.

[0072] The first punch 22 is mounted on the punch mounting part 213, specifically on the side of the punch mounting part 213 facing the upper base 212, and the first punch 22 passes through the upper base 212 and the lower base 214 in sequence through the first punch through hole. In the initial position, the end of the first punch 22 is accommodated in the first punch through hole of the lower base 214.

[0073] A guide post 215 is provided between the upper base 212 and the lower base 214. One end of the guide post 215 is fixed to the lower base 214 by bolt connection, and the other end passes through the upper base 212. The end of the guide post 215 protruding from the upper base 212 is fixed by a limiting ring 216. The upper base 212 and the guide post 215 can slide relative to each other in the axial direction along the guide post 215. The sliding range is defined by the limiting ring 216 and the lower base 214. An elastic element 217 is sleeved on the guide post 215. The two ends of the elastic element 217 abut against the upper base 212 and the lower base 214, respectively. When the upper base 212 slides downward along the guide post 215, the elastic element 217 is compressed.

[0074] The elastic element 217 can be a spring.

[0075] The power source 211 is used to drive the upper base 212, the punch mounting part 213 and the first punch 22 on the punch mounting part 213 to move along the axial direction of the guide post 215. Specifically, it moves downward toward the lower base 214. The first punch 22 passes through the first punch through hole on the lower base 214 and is aligned with the sheet workpiece 100 to punch.

[0076] The power source 211 can be a cylinder.

[0077] During the downward punching process of the upper base 212, the punch mounting part 213, and the first punch 22 on the punch mounting part 213, the elastic element 217 located on the guide post 215 is compressed. After the punching is completed, the power source 211 releases power, the compressed elastic element 217 is released, and the upper base 212, the punch mounting part 213, and the first punch 22 on the punch mounting part 213 are driven by the elastic element 217 to rise along the guide post 215 until the top of the upper base 212 abuts against the limiting ring 216 located at the end of the guide post 215. The upper base 212, the punch mounting part 213, and the first punch 22 return to the initial position and stop rising.

[0078] In this application, the power mechanism 11 includes a servo motor 111 and a lead screw module 112 driven by the servo motor 111. The loading fixture 12 is fixed on the lead screw module 111 and moves along the plane with the lead screw module 112.

[0079] Please see Figure 12 In this application, the receiving fixture 31 also includes a main body 312, with receiving platforms 311 located on top of the main body 312. The number and arrangement of the receiving platforms 311 match the sheet-like workpiece 100, and they are respectively located directly below the first punch 22. Specifically, the receiving platform 311 is a cylindrical pin, and the top of the receiving platform 311 forms a cavity. The shape of the cavity matches the sheet-like workpiece 100 and is used to support the sheet-like workpiece 100.

[0080] With the above configuration, when punching the sheet workpiece 100, each receiving platform 311 corresponds to each of the first punches 22 located at the top. During cutting, the force is applied point-to-point, ensuring precise positioning. The punching force around each sheet workpiece 100 is greater and more concentrated, thus avoiding the problems of sticking and deformation of thin sheet products during punching. The punched product has an excellent appearance and meets the preset precision. At the same time, the punched product falls into the cavity at the top of the receiving platform 311, and the falling distance is extremely short, further eliminating the risk of deformation caused by free fall.

[0081] Please see Figure 13 In this application, the lifting assembly 32 includes a base 321, a slide cylinder 322, and a top plate 323. The base 321 is fixed on a plane, such as the end face of a platform or a flat ground. The slide cylinder 322 is used to drive the top plate 323 to rise and fall. The top plate 323 drives the receiving fixture 31 to rise and fall. Before the punching process, the lifting assembly 32 drives the receiving fixture 31 to rise to contact the bottom of the sheet workpiece 100. After punching, the lifting assembly 32 drives the receiving fixture 31 and the punched sheet workpiece 100 to fall back to the initial position.

[0082] In one embodiment, the base 321 includes a base plate 3211 disposed on a plane and a vertical plate 3212 fixed on the base plate 3211. It also includes a pressure plate 3213 with one end disposed on the plane and the other end extending above the base plate 3211 and pressing against the base plate 3211. The pressure plate 3213 is used to limit and abut against the base plate 3211 to maintain the stability of the structure during use.

[0083] The slide cylinder 322 is fixed on the vertical plate 3212 and arranged in the vertical direction, thereby driving the top plate 323 to move up and down.

[0084] The top plate 323 is installed on the top of the slide cylinder 322 and can be driven to rise and fall by the slide cylinder 322. The top plate 323 is used to drive the receiving fixture 31 to move.

[0085] In this application, the top plate 323 is provided with abutment members 324. The number and arrangement of abutment members 324 are the same as those of each receiving platform 311, and they are located directly below each receiving platform 311. The top of the abutment member 324 forms a cavity. In one embodiment, the abutment member 324 is a cylindrical pin. The above arrangement makes the force transmission between the lifting assembly 32 and the receiving fixture 31 a point-to-surface form, which makes the force transmission more precise and further enhances the punching accuracy, thereby avoiding the problems of sticking and deformation during punching of thin sheet products.

[0086] The punching and edge-removing device in this application also includes a turntable mechanism 4, which includes a turntable 41, a mounting base 42, and a power component 43. The mounting base 42 is disposed on a plane, which can be the end face of a platform or a flat ground. The turntable 41 is mounted on the top of the mounting base 42 and is rotatably connected to the mounting base 42. The power component 43 is used to drive the turntable 41 to rotate.

[0087] The turntable 41 has multiple mounting holes evenly distributed along its circumference. These mounting holes are through holes, penetrating the upper and lower end faces of the turntable 41 and located below the punching assembly 2, specifically between the receiving fixture 31 and the lifting assembly 32. The number of mounting holes can be 8 or 12. The receiving fixture 31 is placed inside the mounting holes, and the lifting assembly 32 is located below the mounting holes. This allows the lifting assembly 32 to pass through the mounting holes and apply an upward force to the bottom of the receiving fixture 31, pushing it upward to meet the punching assembly 2. After punching, the receiving fixture 31 is lowered by the lifting assembly 32, thus carrying the sheet workpiece 100 within the receiving fixture 31. The lifting assembly 32 lowers the receiving fixture 31 to its initial position, placing it inside the mounting holes. The turntable 41 is then rotated around the mounting base 42 by the power component 43 at a certain angle. At this time, the next empty receiving fixture 31 is moved to the area below the punching assembly 2. The above process is repeated until all the empty receiving fixtures 31 on the turntable 41 are carrying sheet workpieces 100. Then, the receiving fixtures 31 and sheet workpieces 100 are removed by a robot or manually, and the empty receiving fixtures 31 are placed in the mounting holes on the turntable 41.

[0088] Please see Figures 14 to 16 The punching and trimming device in this application also includes a scrap material cutting component 5, which is located on the path of the feeding fixture 12 and is used to cut the sprue residue on the sheet workpiece 100. Specifically, it cuts the injection molding residue inside the rectangular hole 101 on the sheet workpiece 100. Since the position of the sheet workpiece 100 has changed after it is separated from the carrier 200, it is not easy to position it accurately. Therefore, in actual application, the sprue residue cutting component is placed before the punching component 2. First, the injection molding residue inside the rectangular hole 101 on the sheet workpiece 100 is cut, and then the sheet workpiece 100 is separated from the carrier 200.

[0089] The scrap material cutting assembly 5 includes a drive component 51, a second punch 52, an upper cover plate 53, a punch carrier 54, and a lower cover plate 55. The structure of the scrap material cutting assembly 5 is similar to that of the punching assembly 2 described above, and the function is also the same. However, due to the different punching locations, the structure and position of the second punch 52 are different from those of the first punch 22.

[0090] The driving component 51 is used to drive the second punch 52 to move downward in the vertical direction to punch the sprue residue in the rectangular hole 101 on the sheet workpiece 100.

[0091] The punch carrier 54 is fixedly connected to the upper cover plate 53.

[0092] Both the upper cover plate 53 and the lower cover plate 55 are disc-shaped, arranged opposite each other with a certain space between them. Each of the upper cover plate 53 and the lower cover plate 55 has a corresponding second punch through-hole for the second punch 52 to pass through, and the diameter of the second punch 52 is slightly larger than its outer diameter. The number and distribution of the second punch through-holes are matched to the second punch 52.

[0093] The second punch 52 is mounted on the punch carrier 54, specifically on the side of the punch carrier 54 facing the upper cover plate 53, and the second punch 52 passes through the second punch through hole sequentially through the upper cover plate 53 and the lower cover plate 55. In the initial position, the end of the second punch 52 is accommodated in the second punch through hole of the lower cover plate 55.

[0094] A guide shaft 56 is provided between the upper cover plate 53 and the lower cover plate 55. One end of the guide shaft 56 is fixed to the lower cover plate 55 by bolt connection, and the other end passes through the upper cover plate 53. The end of the guide shaft 56 protruding from the upper cover plate 53 is fixed by a limiting member 57. The upper cover plate 53 and the guide shaft 56 can slide relative to each other in the axial direction along the guide shaft 56. The sliding range is defined by the limiting member 57 and the lower cover plate 55 respectively. A spring-loaded member 58 is sleeved on the guide shaft 56. The two ends of the spring-loaded member 58 abut against the upper cover plate 53 and the lower cover plate 55 respectively. When the upper cover plate 53 slides downward along the guide shaft 56, the spring-loaded member 58 is compressed.

[0095] The spring-loaded component 58 can be a spring.

[0096] The driving component 51 is used to drive the upper cover plate 53, the punch carrier 54 and the second punch 52 located on the punch carrier 54 to move axially along the guide shaft 56. Specifically, it moves downward toward the lower cover plate 55. The second punch 52 passes through the second punch through hole on the lower cover plate 55 and punches the sheet workpiece 100 to remove the sprue residue.

[0097] During the downward punching process of the upper cover plate 53, the punch carrier 54, and the second punch 52 located on the punch carrier 54, the spring-loaded member 58 located on the guide shaft 56 is compressed. After the punching is completed, the drive member 51 releases power, the compressed spring-loaded member 58 is released, and the upper cover plate 53, the punch carrier 54, and the second punch 52 located on the punch carrier 54 are driven by the spring-loaded member 58 to rise along the guide shaft 56 until the top of the upper cover plate 53 abuts against the limiting member 57 located at the end of the guide shaft 56. The upper cover plate 53, the punch carrier 54, and the second punch 52 return to the initial position and stop rising.

[0098] Please see Figure 18 and Figure 19The punching and edge-removing device in this application also includes a relay component 6, which is located below the scrap material cutting component and has a similar function to the receiving component 3 mentioned above. It is used to bear the punching force of the scrap material cutting component 5 and to receive the sprue scrap after punching.

[0099] The relay assembly 6, from bottom to top, includes a base plate 61, a first cylinder 62, a connecting sleeve 63, a ejector pin guide sleeve 64, and an ejector pin 65. The base plate 61 is set on a flat surface, such as the end face of a platform or a flat ground. The first cylinder 62 is mounted on the base plate 61 and is used to drive the connecting sleeve 63, the ejector pin guide sleeve 64, and the ejector pin 65 to rise and fall. The connecting sleeve 63 is connected to the output shaft of the first cylinder 62. The ejector pin guide sleeve 64 is mounted on the connecting sleeve. The ejector pin guide sleeve 64 has an ejector pin hole 641 inside, and the ejector pin 65 passes through the ejector pin hole 641. A spring 66 is also provided inside the ejector pin hole 641, and the end of the ejector pin 65 abuts against the spring 66.

[0100] Before cutting the sprue residue in the rectangular hole 101 of the sheet workpiece 100, the first cylinder 62 drives the ejector guide sleeve 64 to rise through the connecting sleeve 63 until the top of the ejector 65 abuts against the sprue residue in the upper sheet workpiece 100. Then the residue cutting assembly 5 punches downward, and the sprue residue is clamped by the ejector 65 and the second punch 52. It continues to move downward until the sprue residue is separated from the sheet workpiece 100. The ejector 65 is pressed downward, which drives the spring 66 to compress. The first cylinder 62 is driven by the spring 66 to descend to the initial position. Then the residue cutting assembly 5 rises, and the sprue residue is retained at the end of the ejector 65, thus completing the punching of the sprue residue in the sheet workpiece 100.

[0101] The above configuration enables point-to-point force transmission between the scrap cutting component 5 and the relay component 6, making force transmission more precise and further enhancing the punching accuracy. This avoids problems such as sticking and deformation during punching of thin sheet products, and the sprue scrap remains on the relay component 6 after punching.

[0102] Please see Figure 20 The punching and edge-removing device in this application also includes a scrap material collection component 7, which is located at the lower part of the scrap material cutting component 5 and is used to collect the sprue scrap after punching by the scrap material cutting component 5.

[0103] The waste material collection assembly 7 includes a second cylinder 71, a receiving plate 72, a vacuum connector 73, and a collection container 74. The second cylinder 71 is installed at the lower end of the receiving plate 72 and is used to drive the receiving plate 72 to rise and fall. In practical applications, the receiving plate 72 is set between the waste material cutting assembly 5 and the relay assembly 6. The waste material from the punched sprue is carried on the end of the ejector pin 65. A vacuum environment is formed through the vacuum connector 73, and the waste material is sucked into the collection container 74 for centralized processing.

[0104] The top of the receiving plate 72 has a collection groove 721, and the collection groove 721 has through holes 722. The number and layout of the through holes 722 are the same as those of the ejector pins 65. The ejector pins 65 are located below the through holes 722 and can pass through the through holes 722. One end of the collection groove 721 forms a downward passage 723. A vacuum connector 73 is installed at the lower end of the passage 723, and the vacuum connector 73 is connected to the collection container 74.

[0105] Before the scrap cutting process, the receiving plate 72 is lifted by the second cylinder 71 until its top is in contact with the feeding assembly 1. Then, during the scrap cutting process, the ejector pin 65 of the relay assembly 6 is lifted, passing through the through hole 722. The top of the ejector pin 65 abuts against the bottom of the sprue residue in the rectangular hole 101 on the sheet workpiece 100. At this time, the top of the collection trough 721 is in contact with the feeding assembly 1, with only a small gap between the through hole 722 and the outer wall of the ejector pin 65 connecting it to the outside atmosphere, temporarily creating a relatively sealed space within the collection trough 721. After the scrap cutting process begins, the scrap cutting assembly 5 descends to cut the sprue residue. The sprue residue falls onto the top of the ejector pin 65, and the relay assembly 6 is pressed down to its initial position by the scrap cutting assembly 5. At this time, the end of the ejector pin 65 is still located within the collection trough 721. Vacuum connector 73 is activated, drawing the residual material from the sprue in collection tank 721 into collection container 74 through passage 723. Then, the residual material cutting assembly 5 rises to its initial position, vacuum connector 73 closes, and the residual material collection assembly 7 is lowered to its initial position by the second cylinder 71, completing the residual material cutting and collection.

[0106] A sealing ring can be provided on the outer ring of the collection groove 721 to facilitate a tighter fit with the feeding assembly 1.

[0107] The collection container 74 can be a transparent steel wire hose, which is fitted onto the vacuum connector 73 with a clamp to facilitate observation of the internal collection situation, thereby allowing the residual material from the sprue to be collected and processed.

[0108] Using the punching and edge-removing device of the present invention, automatic punching of small-sized thin sheet products can be realized, solving the problems of easy sticking and insufficient precision during punching of small-sized thin sheet products. The receiving platform is raised to accurately receive and prevent displacement, ensuring that the product does not deform. The product is kept in its original posture for relevant appearance and size inspection, thereby improving production efficiency and product quality.

[0109] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
