Description

Technical field

[0001] The present application relates to the technical field of pre-processing equipment, and in particular to a material strip cutting device. [Background Technology]

[0002] During the pre-processing of metal terminals for overmolding, the protective corners on the material strip need to be removed first, and then the material strip with terminals needs to be cut into single sections to obtain individual terminal workpieces, which facilitates subsequent cleaning, adhesive primer coating, and liquid silicone injection molding.

[0003] like Figure 1 As shown, the terminal strip 1 includes terminals 11, protective corners 13, and a connecting portion 15 fixedly connecting the terminals 11 and the protective corners 13. The connecting portion 15 is provided with a positioning hole 151. In order to accurately cut the strip, the cutting equipment provided in the related art usually has a positioning post at the workstation that matches the positioning hole 151 of the strip. The terminal strip 1 is inserted into the positioning post through the positioning hole 151 to quickly and accurately position and install it at the workstation of the cutting equipment.

[0004] However, after the cutting device completes the cutting operation, the terminal 11, the protective corner 13, and the connecting portion 15 are separated from each other, and the connecting portion 15, which is a waste material, is still mounted on the positioning post of the cutting device. Because the positioning post and the positioning hole match each other and are small in size, manual removal of the waste material is difficult, time-consuming, and labor-intensive, and the processing efficiency is low.

[0005] Moreover, there is no corresponding collecting device for the cut terminals 11 , and a large number of the terminals 11 need to be manually loaded onto other equipment before continuing subsequent operations, which is time-consuming and labor-intensive, and has low processing efficiency.

[0006] In summary, how to quickly remove waste and collect workpieces is a problem that those skilled in the art urgently need to solve. [Summary of the invention]

[0007] In order to solve the above problems, quickly remove waste materials and collect workpieces, the present application provides a strip cutting device.

[0009] In some embodiments, the material lifting module includes a lifting plate and a connecting member, and the lifting plate is fixedly connected to the cutting module through the connecting member to follow the movement of the first punch; the lifting plate is provided with an arm, and the arm is received in the receiving groove of the second punch. When the lifting plate moves, the arm leaves the receiving groove and lifts up the waste part of the material strip covering the receiving groove, and the waste part of the material strip is taken away from the second punch by the arm.

[0010] In some embodiments, the material lifting module further includes a bracket and a limiting member, wherein the bracket is fixedly connected to the lifting plate, and the bracket is provided with a through hole; one end of the limiting member is fixedly connected to the cutting module, and the other opposite end is provided with the through hole, the size of the through hole is larger than the size of the limiting member, and the limiting member limits the bracket to move with the lifting plate within a certain stroke.

[0011] In some embodiments, the collection module includes a support body and a baffle that are fixedly connected, and the support body and the baffle cooperate to form a slide rail groove.

[0012] In some embodiments, the slide rail groove includes a first sliding segment and a second sliding segment connected to each other, and the slope of the first sliding segment is greater than the slope of the second sliding segment.

[0013] In some embodiments, a workpiece carrier is further included, wherein the workpiece carrier is provided with a loading cavity corresponding to the slide rail groove, and the loading cavity is used to accommodate and load the workpiece.

[0014] In some embodiments, the support body is provided with a fixing groove, and the fixing groove is adapted to be arranged to fit the workpiece carrier so that an inner wall of the fixing groove engages with the workpiece carrier.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present application.

[0027] In addition, if there are descriptions involving "first," "second," etc. in the embodiments of this application, such descriptions are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0028] The strip cutting device 2 is used to cut the strip to obtain the workpiece to be processed, specifically, to cut the single-sided strip material, such as connector terminals. Figure 1 and Figure 2 , Figure 2 A material strip cutting device is provided in one embodiment of the present application, and is described by taking cutting the terminal material strip 1 as an example.

[0029] The material strip cutting device 2 includes a cutting module 21, a connecting structure 23, a lifting module 25, a collecting module 27 and a workpiece carrier 29. The cutting module 21 includes a first punch 211 and a second punch 213 arranged opposite to each other, and the terminal material strip 1 is fixedly mounted on the second punch 213. The connecting structure 23, the lifting module 25 and the collecting module 27 are respectively fixedly connected to the cutting module 21, and the workpiece carrier 29 is detachably connected to the collecting module 27. The connecting structure 23 is also connected to other driving devices (not shown in the figure), and is driven by the driving device to drive the first punch 211 toward or away from the second punch 213 to cut the cutting points 111 and 131 of the terminal material strip 1. The lifting module 25 moves synchronously with the first punch to lift the discarded connecting part 15, so that the waste material is separated from the cutting module 21 for easy removal. The cut terminals 11 fall into the collecting module 27 and are loaded onto the workpiece carrier 29 under the guidance of the collecting module 27. The workpiece carrier 29 allows batch transfer of the terminals between the cutting operation and other operation processes, resulting in efficient processing and saving time and effort.

[0030] It is understandable that the driving device can be an independent driving device, such as a motor, a cylinder or a hydraulic device; it can also utilize the driving device of other processing equipment, such as a servo drive system of a CNC (Computer Numerical Control)-based processing center.

[0031] See also Figure 3 , Figure 3 for Figure 2 The three-dimensional structure decomposition diagram of the material strip cutting device shown. The cutting module 21 includes the first punch 211, the second punch 213, the adjustment component 215 and the mounting base 217. The assembly of the first punch 211, the second punch 213 and the adjustment component 215 is detachably connected to the mounting base 217 and fixedly installed to the processing site through the mounting base 217, for example, by bolting or welding. In this embodiment, the second punch 213 is detachably connected to the mounting base 217 by bolting. The first punch 211 and the second punch 213 are respectively fixedly connected to the adjustment component 215, and the two realize relative movement toward or away from each other through the adjustment component 215, and cooperate to form a shear force to cut the cutting points 111 and 131 of the terminal material strip 1.

[0032] For the convenience of description or illustration, in this embodiment, it is defined that the first punch 211 and the second punch 213 move relative to each other along the first direction Z.

[0033] Specifically, refer to Figure 3 and Figure 4 , Figure 4 for Figure 2 The figure shows a schematic cross-sectional structure diagram of a strip cutting device. The adjustment assembly 215 includes a pre-pressing member 2151, a guide post 2153, and a guide sleeve 2155. The pre-pressing member 2151 is disposed between the first punch 211 and the second punch 213 and is fixedly connected to the first punch 211, for example, by bolts. The pre-pressing member 2151 has a first through-hole 21511, and the second punch 213 has a corresponding second through-hole 2131. The inner diameters of the first through-hole 21511 and the second through-hole 2131 match the dimensions of the guide sleeve 2155, which is respectively accommodated in the first through-hole 21511 and the second through-hole 2131. The guide sleeves 2155, which are respectively accommodated in the first through-hole 21511 and the second through-hole 2131, are sleeved on the same guide post 2153, and the guide sleeves 2155 and the guide post 2153 are arranged in a transitional fit.

[0034] The guide post 2153 is a cylindrical structural component that provides guidance for relative movement. One end of the guide post 21531 is a fixed end, and the other end is a guide end 21533. Multiple oil grooves 21535 are provided between the fixed end 21531 and the guide end 21533, and the multiple oil grooves 21535 are spaced apart. The fixed end 21531 is fixedly connected to the first punch 211. Specifically, the first punch 211 is provided with a third through hole 2111, and the guide post 2153 is partially received in the third through hole 2111. The centerlines of the first through hole 21511, the second through hole 2131, the third through hole 2111, the guide sleeve 2155, and the guide post 2153 overlap and are all arranged parallel to the first direction. The fixed end 21531 is fixedly connected to the inner wall of the third through hole 2111, for example, by welding or riveting.

[0035] The guide sleeve 2155 is a hollow tube structure that provides guidance for relative movement. The inner wall of the hollow tube is configured to transitionally fit with the guide post 2153 to achieve relative sliding. One end of the guide sleeve 2155 is a head 21551, which is fixedly connected to the inner wall of the first through hole 21511 or the second through hole 2131, for example, by riveting, to prevent the guide sleeve 2155 from being pulled out of the first through hole 21511 or the second through hole by the guide post 2153.

[0036] In this embodiment, there are two guide pins 2153 and four guide sleeves 2155. In other embodiments, the number of guide pins 2153 may be greater or lesser, but at least one. The number of guide pins 2153 is related to the overall specifications of the strip cutting device 2 and can be adjusted according to actual needs. The number of guide sleeves 2155 is related to the number of guide pins 2153 and is an integer multiple of the number of guide pins 2153.

[0037] Please refer to Figure 4 The pre-press 2151 and the second punch 213 are positioned so as to maintain alignment along a shear plane α. The shear plane α is parallel to the first direction Z and is the common plane where the cutting points 111 and 113 lie when the terminal strip 1 is loaded into the strip cutting device 2. It is understood that the cutting module 21 applies a shear force to the terminal strip 1 along the shear plane α.

[0038] The first punch 211 includes a main body 2113 and a blade 2115 that are fixedly connected. The main body 2113 has two opposite first and second ends. The first end is fixedly connected to the connecting structure 23, for example, by bolting or welding. One end of the blade 2115 is fixedly connected to the second end of the main body 2113, and the other end thereof abuts against the side of the pre-pressed part 2151 facing the shearing surface α. Figure 2 The blade body 2115 is provided with an escape groove 21151 on a side away from the shearing surface α. The shape and size of the escape groove 21151 are adapted to the terminal 11 to avoid the terminal 11. The number of the escape grooves 21151 corresponds to the number of the terminals 11, and the plurality of the escape grooves 21151 are arranged at intervals. In this embodiment, eight escape grooves 21151 are used as an example for illustration. It is understood that in other embodiments, the number of the escape groove 21151 can be more or less, but at least one.

[0039] In order to limit the shear force provided by the first punch 211, the cutting module 21 further includes a buffer 219, one end of which abuts the first punch 211, and the other end thereof abuts the pre-press 2151. The first punch 211 is driven by the connecting structure 23 to move, and after a certain movement, the pre-press 2151 abuts the second punch 213. The first punch 211 and the pre-press 2151 cooperate to compress the buffer 219. The buffer 219 provides an opposite force to partially offset the acceleration of the first punch 211, thereby limiting the shear force provided by the first punch 211 to the terminal strip 1. The buffer 219 is made of an elastic material, such as silicone, rubber, or a metal spring. In this embodiment, the buffer 219 can be silicone.

[0040] See also Figure 5 , Figure 5 for Figure 2 The partial assembly diagram of the strip cutting equipment in one state is shown. Figure 5 The assembly relationship between the terminal strip 1 and the strip cutting device 2 is shown. A positioning post 2133 is provided on the side of the second punch 213 near the pre-press 2151. The positioning post 2133 is adapted to the positioning hole of the terminal strip 1. The connecting portion 15 of the terminal strip 1 is sleeved onto the positioning post 2133 through the positioning hole 151, and the protective corner 1313 of the terminal strip 1 and the terminal 11 are suspended. After the cutting operation is completed, the terminal 11 is obtained as a workpiece, and the connecting portion 15 is discarded.

[0041] Please refer to Figure 4 and Figure 5 The collection module 27 includes a fixedly connected support body 271 and a baffle 273. The support body 271 is fixedly connected to the side of the mounting base 217 near the shear surface α, for example, by screwing or welding. The side of the support body 271 away from the mounting base 217 is an inclined arc surface. The baffle 273 is spaced apart from the inclined arc surface. The baffle 273 and the inclined arc surface cooperate to form a slide rail groove 275. The end of the slide rail groove 275 near the shear surface α is an entrance end 2751, and the other end opposite is an exit end 2753. The direction from the entrance end 2751 to the exit end 2753 is the sliding direction X of the terminal 11.

[0042] The slide rail groove 275 includes a first slide segment 2755 and a second slide segment 2757 connected along the slide direction X. The slope of the first slide segment 2755 is greater than the slope of the second slide segment 2757. In this embodiment, the first slide segment 2755 and the second slide segment 2757 are directly connected. In other embodiments, the first slide segment 2755 and the second slide segment 2757 can be indirectly connected via other slide segments. It will be understood that the inner wall of the slide rail groove 275 has a surface with a continuously changing curvature to prevent damage to the terminal 11 due to impact or excessive friction.

[0043] The support body 271 is provided with a fixing groove 277 on the side away from the shear surface α, and the fixing groove 277 is adapted to be arranged with the workpiece carrier 29 so that the inner wall of the fixing groove 277 engages with the workpiece carrier 29. The workpiece carrier 29 is provided with a loading cavity 291 corresponding to the slide rail groove 275, and the loading cavity 291 is used to accommodate the loaded terminal 11, and the loading cavity 291 is connected to the outside space through the opening 293. The depth of the fixing groove 277 is arranged to match the opening 293 so that the opening 293 is completely exposed. The workpiece carrier 29 is also provided with a gripping portion 295, and the gripping portion 295 protrudes outward and extends from the outer surface of the workpiece carrier 29. By gripping the gripping portion 295, the workpiece carrier 29 can be quickly transferred.

[0044] Please refer to Figure 3 、 Figure 4 and Figure 5 The lifting module 25 includes a bracket 251, a lifting plate 253, a connecting member 255 and a limiting member 257. The bracket 251 is disposed adjacent to the cutting module 21. Specifically, in this embodiment, the bracket 251 is disposed at an end of the cutting module 21 away from the shearing surface α.

[0045] The bracket 251 has a gantry structure and includes a crossbeam 2511 and legs 2513. The legs 2513 are fixedly connected to two opposite ends of the crossbeam 2511, and the lifting plate 253 is fixedly connected to one side of the crossbeam, for example, by bolting or welding. The lifting plate 253 is provided with an arm 2531. The end of the second punch 213 near the first punch 211 is correspondingly provided with a receiving groove 2135. The arm 2531 is received in the receiving groove 2135. The receiving groove extends from the side of the second punch 213 near the shear surface α to the opposite side through the receiving groove 2135. One end of the arm 2531 is fixedly connected to the lifting plate 253, and the opposite end extends toward the shear surface α.

[0046] Since the material strip 1 is fixedly mounted on the material strip cutting device through the positioning hole, the connecting portion 15 of the material strip 1 is covered on the receiving groove. The lifting plate 253 and the pre-pressing member 2151 are fixedly connected through the connecting member 255. The driving device drives the connecting structure 23 to drive the first punch 211 to move, thereby driving the pre-pressing member 2151 to move, thereby driving the connecting member 255 to move, and thereby driving the lifting plate 253. The connecting member 255 is a columnar structure, one side of the connecting member 255 is fixedly connected to the lifting plate 253, and the other adjacent side is fixedly connected to the first punch 211, for example, by bolting or riveting. When the lifting plate 253 moves, the arm 2531 of the lifting plate 253 leaves the receiving groove 2135 and lifts the connecting portion 15 of the terminal material strip 1, so that the connecting portion 15 is separated from the positioning column 2133, which facilitates the removal of waste.

[0047] The leg 2513 of the bracket 251 is provided with a through-hole 25131 extending from the side of the leg 2513 closest to the mounting base 217 to the side of the leg 2513 further away from the mounting base 217. One end of the stopper 257 is fixedly connected to the mounting base 217, for example, by bolting or riveting, while the other end is provided with the through-hole 25131. The through-hole 25131 is larger than the size of the stopper 257. When the bracket 251 is moved by the lifting plate 253, the stopper 257 allows the bracket 251 to move within a certain range. Further movement of the bracket 251 is prevented beyond this range. This configuration limits the movement of the lifting plate 253 to a certain range, preventing the lifting plate 253 from moving too far and potentially causing the connecting portion 15 to fall to another location on the device.

[0048] Please refer to Figures 1 to 6 , Figure 6 for Figure 2 The schematic diagram of partial assembly of the strip cutting device in another state is shown. The working process of the strip cutting device 2 is described as follows:

[0049] After the slitting operation, the terminal strip 11 obtained is Figure 1 The terminal strip 11 is fixedly mounted on the strip cutting device 2 through the positioning hole 151. The external driving device drives the connecting structure 23 to move the first punch 211 toward the second punch 213 to cut the terminal strip 1 at the cutting points 111 and 131.

[0050] After the cutting operation is completed, the terminals 11 fall into the inlet end 2751 of the collection module 27 and slide along the slide rail 275 to the outlet end 2753. Under the action of inertia, the terminals 11 pass through the opening 293 and enter the loading chamber 291 of the workpiece carrier 29. By moving the workpiece carrier 29, the terminals 11 are transferred in batches for further processing.

[0051] After the cutting operation is completed, the external driving device drives the connecting structure 23 to move the first punch 211 away from the second punch 213, thereby driving the pre-pressing member 2151 to move, and further driving the connecting member 255 to move, and further driving the lifting plate 253. As the lifting plate 253 moves, the arm 2531 of the lifting plate 253 leaves the receiving groove 2135 and lifts the connecting portion 15 of the terminal strip 1, so that the connecting portion 15 is separated from the positioning post 2133, facilitating the removal of waste material.

[0052] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
